for federal income tax purposes to a Participant (or his or her Beneficiary)
prior to the actual payment of benefits under the Plans; and

II.  ESTABLISHMENT OF THE TRUST

     2.1 Trust. The Company hereby establishes the Trust with the Trustee,
which Trust shall consist of such sums of money and other property acceptable
to the Trustee as from time to time have been and shall be paid or delivered by
the Company to the Trustee as provided herein. All such money and other
property, all investments and reinvestments made therewith, or the proceeds
thereof, and all investment earnings and profits thereon, less all payments and
charges as authorized herein, shall constitute the Trust Fund. The Trust Fund
shall be held in trust by the Trustee, and shall be dealt with in accordance
with the provisions of this Trust.

     2.2 Description of Trust. The Company represents and agrees that:




                                     - 7 -

 
<PAGE>   13

           (a) the Trust is intended to be a grantor trust under IRC Section
      Section  671-678, and shall be construed accordingly. The Company intends
      and agrees that it is the "owner" or grantor of the Trust in its
      entirety, as that term is defined in subpart E, part I, subchapter J,
      chapter 1, subtitle A of the IRC and that, for income tax purposes, all
      income, deductions, and credits of the Trust Fund belong to it as owner,
      and will be included on its income tax or other required tax returns, and
      any income tax determined to be payable as a result thereof will be the
      sole obligation of, and will be paid by, the Company;

           (b) a true and correct copy of the Plan, as in effect on the
      Effective Date hereof, is attached hereto as Exhibit A. The Company shall
      file with the Trustee, promptly upon its adoption, a true and correct
      copy of each amendment to the Plan;

           (c) the Trust Fund is to be used to satisfy the legal obligations of
      the Company to Participants under the Plan as provided herein, subject to
      the claims of General Creditors in the event of Insolvency, and the
      balance of the Trust Fund, if any, remaining after payment of the
      Company's obligation to Participants under the Plan will revert to the
      Company in accordance with the Trust;            

           (d) contributions by the Company to the Trust which are made
      coincident with and subsequent to the Effective Date shall be in amounts
      determined under Article III hereof. The Company agrees to fund the Trust
      as provided therein;

           (e) the principal of the Trust, and any earnings thereon shall be
      held by the Trustee separate and apart from other funds of Company, and
      shall be used exclusively for the uses and purposes as herein set forth;

           (f) the Trust established under this agreement does not fund and is
      not intended to fund the Plan, or any other benefit plan or program of
      the Company. Neither the establishment of the Trust, nor the payment or
      delivery of assets to the Trustee shall vest any Participant in any
      right, title, or interest in or to any assets of the Trust Fund;

           (g) participants shall have no preferred claim on, or any beneficial
      ownership interest in, assets of the Trust. To the extent that any
      Participant



                                     - 8 -

 
<PAGE>   14


      acquires the right to receive payment(s) under the Plan, any
      such right shall be mere unsecured contractual rights of Participants
      against the Company, and such Participants (or their Beneficiary(ies))
      shall have only the unsecured promise of the Company that such payment(s)
      will be made. Any assets held by the Trust will be subject to the claims
      of General Creditors under federal and state law in the event of
      Insolvency, as defined herein, with no preference whatsoever given to
      claims of employees or Participants over claims of other unsecured
      creditors of the Company; and

           (h) to the extent the Plan is covered by ERISA, the Plan is a plan
      for a select group of management or highly compensated employees, and as
      such are exempt from the application of ERISA except for the disclosure
      requirements applicable to such plan, for which the Company bears full
      responsibility as to compliance. The Company further represents that the
      Plan is not qualified under IRC Section  401  and therefore, is not
      subject to any IRC requirements applicable to tax-qualified plans.

      2.3 Irrevocability. Except as provided in Article 9 and this Section
2.3, the Trust shall be irrevocable from the effective date, and the assets of
the Trust Fund shall be held in accordance with the provisions hereof for the
exclusive purpose of providing for the payment of the Company's obligations to
pay benefits to Participants under the Plan and to satisfy the claims of General
Creditors in the event of Insolvency, and defraying the expenses of the Trust. 
Except as provided in Section 6.6 and Section 6.8 and in the event of
Insolvency, no part of the income or corpus of the Trust Fund shall be
recoverable by or for the benefit of the Company.

     2.4 Acceptance by the Trustee.  The Trustee accepts the Trust established
under this Trust Agreement on the terms and subject to the provisions set forth
herein, and agrees to discharge and perform fully and faithfully all of the
duties and obligations imposed upon it under this Trust.

III. CONTRIBUTIONS

     3.1 Calculations of Funding Amount.  By September 30, 1995, the Company
shall contribute to the Trust the Funding Amount as determined on the first
Valuation Date. As of each Valuation Date, and until the entire Trust Fund has
been distributed, the Company (or, after a Change of Control, the Company's
independent public accountants) shall recalculate the Funding Amounts.



                                     - 9 -

 
<PAGE>   15


     3.2 Contributions as of Each Valuation Date.  During the life of the Trust
but no later than September 30 of each year, commencing no later than September
30, 1996, the Company shall contribute to the Trust such amount as is necessary
to make trust assets equal the Funding Amount as of the previous Valuation
Date. The Plan Administrator or its delegate (or, after a Change of Control,
the Company's independent public accountants) shall provide the Trustee with
written notice of the amount of the necessary contribution on or before the
date such contribution is due to the Trust. Any such payments to the Trustee do
not discharge or release the Company of its obligation under the Plan or
Section 6.2 to pay benefits to Participants under the Plan, and shall at all
times be subject to the provisions of Article VII.

     3.3 Reserved.

     3.4 No Dilution of Trust.  After a Change of Control, the Exhibit B in
effect on the date of a Change of Control shall not be amended to include a
Participant not named in the Exhibit B in effect on the date of a Change of
Control, unless pursuant to the requirements of this Section 3.4, at the time
of delivery to the Trustee of a proposed amended Exhibit B (the "Delivery
Date"), the Company shall deliver to the Trustee a determination by the
Company's independent public accountants as of the Delivery Date of the 
proposed amended Exhibit B of the Funding Amount calculated based on the 
Participants named in the Exhibit B in effect on the Date of the Change
of Control and any new or additional Participants named in the proposed amended
Exhibit B (the "New Funding Amount") and (b), assets in an amount necessary to
make the trust assets equal the New Funding Amount. If the Trustee determines
that assets of the Trust Fund, including such assets as are delivered by the
Company on the Delivery Date, equal or exceed the New Funding Amount, the
Trustee shall accept the amended Exhibit B. Any amended Exhibit B so accepted
shall be deemed incorporated with the same effect as if otherwise included
herein. Unless an Exhibit B amended after a Change of Control is accepted by the
Trustee as provided in this Section, the Trustee shall have no liability,
responsibility, or obligation with respect to a Participant named in any amended
Exhibit B unless such Participant is named in the Exhibit B then in effect on
the date of a Change of Control.

     3.5 Collection.  In the event the Company fails to pay over to the Trustee
within one hundred and twenty (120) days of notice and demand from the Trustee
(or, upon the occurrence of a Potential Change of Control or a Change of
Control, within seven (7) days of notice and demand from the Trustee), any
amount determined to be payable by the Company to the Trustee under Sections
3.2, 6.5 or 7.4(a) of the Trust, the Trustee may commence legal action, (which
is expressly deemed to include without


                                     - 10 -

 
<PAGE>   16

limitation an alternate dispute resolution proceeding), to compel the Company to
pay to the Trustee any amount determined to be payable to it under the Trust.
The Trustee may bring such action against the Company in any court of competent
jurisdiction, and shall be entitled to recover for the benefit of the Trust from
the Company such amount, plus interest for each day at the rate of interest per
annum of five (5) percentage points in excess of the prime lending rate as
announced by NBD Bank, from the due date specified in the Trustee's notice
and demand (or the date(s) from which pro rata payments were made, if such
action is brought by the Trustee pursuant to Section 6.5 hereof) to the date of
payment, plus all costs of collection, including reasonable attorneys fees and
costs of litigation. The Trustee is authorized to bring action to compel payment
by the Company, and, in connection with reasonable claims for delinquent
contributions by the Company, to retain, at the expense of the Company, counsel
and other appropriate experts, including actuaries and accountants, to aid it in
pursuing litigation for collection against the Company. The Trustee's
anticipated reasonable costs and expenses incurred pursuant to this Section 3.5
are payable by the Company in advance; and should the Company not make timely
payment, the Trustee may charge the Trust Fund for such reasonably anticipated
costs and expenses. The Trustee shall in no event be required to advance or
expend its own funds in order to comply with the provisions of this Section 3.5.

IV.  ACCOUNTING AND ADMINISTRATION

     4.1 Trustee Recordkeeping.  The Trustee shall keep or cause to be kept
accurate and detailed records of any investments, receipts, disbursements, and
all other transactions required to be made by the Trustee hereunder, in
accordance with such rules as may be established by the Company, including such
specific records as shall be agreed upon in writing between the Company and the
Trustee. All accounts, books, and records relating thereto shall be open to
inspection and audit at all reasonable times by any person designated by the
Company. All such accounts, books, and records shall be preserved (in original
form, or on microfilm, magnetic tape, or any other similar process) for such
period as the Company may determine, and the Trustee may only destroy such
accounts, books, and records after first notifying the Company in writing of
its intention to so, and transferring to the Company any of such accounts,
books, and records requested by the Company.

     4.2 Company Recordkeeping.  The Company shall keep full, accurate, and
detailed books and records with respect to the Participants and benefits paid

     4.3 Periodic Accounting.  Within sixty (60) days following a Valuation
Date, the Trustee shall deliver to Company a written accounting, dated as of
the Valuation Date, of its administration of the Trust Fund during such year or
during the period from the most recent Valuation Date to the date of such
current Valuation Date, which accounting shall be in accordance with the
following provisions:

           (a) Such accounting shall set forth all investments, receipts,
      disbursements, and other transactions effected the by Trust Fund during
      the preceding year, or during the period from the most recent Valuation
      Date to the date of such current Valuation Date, including a description
      of all securities and investments purchased and sold, with the cost or
      net proceeds of such purchases or sales (accrued interest paid or
      receivable being shown separately), and showing all cash, securities or
      other property held in the Trust Fund, less liabilities known to the
      Trustee (other than liabilities to Participants entitled to benefits 
      under the Plans) at the end of such year or other period, as the case
      may be. In making a valuation, all cash, securities or other property
      held in the Trust Fund shall be valued at their then fair market value,
      and shall be in a format as may be established by the Company. A copy of
      each accounting so delivered to the Company shall be open to inspection
      at the office of the Trustee during normal business hours.

           (b) If within ninety (90) days after the filing of such written
      accounting, the Company has not delivered to the Trustee notice of any
      objection to any act or transaction of the Trustee, the initial
      accounting shall become an account stated as between the Trustee and the
      Company. If any objection has been delivered to the Trustee by the
      Company, and if the Company is satisfied that it should be withdrawn, the
      Company shall signify its approval of the accounting in writing filed
      with the Trustee, and the accounting shall become an account stated as
      between the Trustee and the Company. If the accounting is adjusted
      following an objection thereto, the Trustee shall file and deliver the
      adjusted accounting to the Company. If within fifteen (15) days after
      such filing of an adjusted accounting, the Company has not delivered to
      the Trustee notice of any objection to the transactions as so adjusted,
      the adjusted accounting shall become an account stated as between the
      Trustee and the Company.

           (c) Unless an accounting is fraudulent, when it becomes an account
      stated, it shall be finally settled, and the Trustee shall, to the extent
      permitted by applicable law, be forever released and discharged from all
      liability  and


                                     - 12 -

 
<PAGE>   18

     accountability with respect to the propriety of its acts and 
     transactions shown in such accounting.

     4.4 Administrative Powers of Trustee.  Except to the extent that authority
with respect to the administration of the Trust has been allocated to others in
accordance with this Trust, and subject to Article V, the Trustee shall have
exclusive authority and discretion to manage and administer the Trust. The
Trustee shall act with the care, skill, prudence and diligence under the
circumstances then prevailing that a prudent person acting in like capacity and
familiar with such matters would use in the conduct of an enterprise of like
character and with like aims, provided, however, that Trustee shall incur no
liability to any person for any action taken pursuant to a direction, request

notice to the Investment Manager and the Trustee.

     The Company may by written notice to the Trustee assume investment

     5.4 Reserved.

     5.5 Single Fund.  All assets of the Trust Fund and of each investment
fund, and the income thereon, shall be held and invested as a single fund, and
the Trustee shall not make any separate investment of the Trust Fund, or make
any separate investment fund, for the account of any Participant or other
General Creditors prior to receipt of directions to make payments to such

in conformance with the provisions of Section 6.3. Payments to Participants
pursuant to this Article VI shall be made by the Trustee to the extent that
funds in the Trust Fund are sufficient for such purpose, and shall at all times
be subject to the provisions of Article VII. In the event the Company
determines that it will pay benefits directly to Participants as they become
due under the terms of the Plan, the Company shall notify Trustee of its
decision prior to the time amounts are payable to Participants.

                                     - 20 -



 
<PAGE>   26


     6.2 Obligation of the Company to Make Payments to Participants.
Notwithstanding anything in the Trust to the contrary, the Company shall remain
primarily liable to pay benefits under the Plan. Distributions to Participants
from the Trust Fund shall discharge, reduce, and offset the Company's
obligation to pay benefits to or on behalf of the Participant, to the extent of
the distributions, with respect to the Plan. If the Company's obligation to pay
a benefit under the Plan is not fully discharged, reduced, and offset by a
distribution from the Trust, then the Company shall make the balance of each
such benefit payment as it becomes due.

     6.3 Distributions to Participants.  Distributions which shall be made from
the Trust Fund to pay benefits in accordance with the Plan shall be initiated
by:

           (a) written direction to the Trustee from the Plan Administrator,
      which direction shall certify that such distribution(s) is (are) in
      accordance with the Plan, and specify the timing, form, payee, and amount
      of such benefit payments, including any federal, state, or local income
      taxes to be withheld, and the Trustee shall make or commence the directed
      distributions after receipt of such written direction; or

           (b) by the submission to the Trustee by a Participant of a certified
      copy of the non-appealable order of an appropriate forum with
      jurisdiction to settle a claim for payment(s) under the Plan.

     6.4 Reserved.

     6.5 Insufficient Trust Fund Assets.  If at any time the Trustee determines
or is advised that the Trust Fund does not have sufficient assets to permit the
Trustee to make a payment property directed pursuant to this Trust, including 
a payment provided for under Section 10.7 of this Trust, the Trustee shall pay
any benefits due (if otherwise payable hereunder) to Participants on a pro rata
basis as directed by the Plan Administrator, and the Company shall make the 
balance of such payments as they become due. If the Plan Administrator 
determines that the Trust Fund does not have sufficient funds to provide for
the payment of all amounts otherwise payable to Participants (or their 
Beneficiary(ies)) from the Trust under the Plans, it shall notify the Company
and the Trustee of the amount of the deficiency, and, within forty-five (45)
days of such notice, the Company deposit in trust with the Trustee the
additional amounts needed to make such payments. Upon receipt of such amount by
the Trustee from the Company, proceeds shall first be used by the Trustee to
pay any benefits

                                     - 21 -


 
<PAGE>   27

previously due remaining unpaid, in the order in which they were due,
pursuant to Plan Administrator instructions.

     6.6 Payment of Excess Assets to Company.  Subject to Article VII, and
except as otherwise provided in this Section and Section 6.8 hereof, the
Company shall have no right or power to direct the Trustee to return to the
Company or to divert to others any of the Trust Fund before payment of all
benefits due or to become due have been made to Participants (or their
Beneficiary(ies)) pursuant to the terms of the Plan. If, as of a Valuation
Date, and based on the fair market value of the Trust Fund as determined by the
Trustee in accordance with Section 4.3 hereof, the Trust Fund holds Excess
Assets, then in the event the Trustee has received within ninety (90) days
after the most recent Valuation Date a written request executed by the Company,
the Trustee shall transfer to the Company, within thirty (30) days after the
receipt of the request, and provided that a Potential  Change of Control Period
does not exist on the date of the transfer, such assets of the Trust Fund
selected by the Company which have a fair market value equal to the amount of
such Excess Assets, after converting such assets to cash if requested by the
Company. Any payment of Excess Assets to the Company under this Section shall
not discharge or release the Company of its obligation to make any contribution
required under Article III (including the requirement of a Company contribution
to the Trust upon the occurrence of a Potential Change of Control or a Change
of Control), and its obligation to pay benefits to Participants under the Plan.
Any payment of Excess Assets in accordance with this Section shall be subject
to the provisions of Article VII.

     6.7 Company to Pay Withholding and Employment Taxes.  Any amount paid to
a Participant by the Trustee in accordance with this Article VI shall be reduced
by the amount of taxes required to be withheld pursuant to Plan Administrator
instructions, and the Trustee shall inform the Company of all amounts so        
withheld. The Company shall direct that the Trustee shall either 

           (a) pay to the Company a sum equal to the amount of such taxes as are
      required to be withheld, whereupon the Company shall have full 
      responsibility for the payment of all withholding taxes to the 
      appropriate taxing authorities, or

           (b) pay such taxes directly to the appropriate taxing authorities
      for the benefit of the Company.

The Company shall be solely responsible for the payment of any employment taxes
for which it is directly liable as a result of payments by the Trustee. The
Company shall

                                     - 22 -


 
<PAGE>   28

furnish each Participant with the appropriate tax information form evidencing
payments under the Trust and the amount(s) thereof.

     6.8 Payment in Reversion to Company.  Subject to Article VII, upon receipt
of written certification from the Company that all obligations of the Company
to Participants with respect to the Plan have been satisfied, and if the Trust
Fund shall have any assets remaining, the Trustee shall distribute such
remaining assets of the Trust Fund to the Company, after converting such assets
to cash if requested by the Company, subject to the Trustee's right to retain
such reasonable amount for compensation and expenses as provided in Section
10.7. The Trust shall thereafter terminate as provided in Section 9.2.


     6.9 Reserved.

VII. PAYMENTS ON INSOLVENCY OF THE COMPANY


     7.1 No Security Interest.  No Participant shall have any claim on or
beneficial ownership interest in the Trust Fund before such assets are paid to
the Participant, except as an unsecured creditor of the Company. The Company
shall not create a security interest in the Trust Fund in favor of any
Participant or any other General Creditor.  At all times during the continuance
of this Trust, as provided in this Article VII hereof, the principal and income
of the Trust Fund shall be subject to the claims of General Creditors under
federal and state law. If at any time the Trustee has received notice as
provided below that Company is Insolvent, Trustee shall discontinue payments to
Participants, and shall hold assets of the Trust Fund for the benefit of the
Company's General Creditors, pursuant to the provisions of Section 7.3, with no
preference whatsoever given claims of employees or Participants over claims of
other unsecured creditors of the Company.

     7.2 Determination of Insolvency.  Notwithstanding any other provisions of
this Trust, the following provisions shall apply:

           (a) The Board of Directors and the Chief Executive Officer of the
      Company shall have the fiduciary duty and responsibility on behalf of
      General Creditors to notify the Trustee promptly in writing in the event
      the Company is Insolvent, and the Trustee shall have the right to rely
      thereon to the exclusion of all directions or claims for payment made
      thereafter by Participants.

           (b) If the Trustee has actual knowledge that the Company is
      Insolvent, the Trustee shall act in accordance with Section 7.3 hereof.

           (c) Unless the Trustee receives written notice from the Board of
      Directors or the Chief Executive Officer of the Company that the Company
      is Insolvent, or from a person claiming to be a General Creditor and
      claiming that the Company is Insolvent, the Trustee shall have no duty to
      inquire whether the Company is Insolvent. If the Trustee receives a
      written allegation from a person claiming to be a General Creditor that
      the Company is Insolvent, the Trustee's only duty of inquiry shall be to
      request that the Company's independent public accountants determine
      whether the Company is Insolvent, and shall suspend benefit payments
      pending such determination. If the Company's independent public
      accountants advise the Trustee that the Company is not Insolvent, it
      shall resume payments in accordance with this Trust. If the Trustee
      receives notice of the Company's Insolvency pursuant to this Section
      7.2(c), it shall act in accordance with this Section and Section 7.3
      hereof.

     7.3 Payments When Company Is Insolvent.  Notwithstanding any other
provision of this Trust to the contrary, if the Trustee has actual knowledge as
described in 7.2(b), has been advised pursuant to 7.2(c) or receives actual
notice described in Section 7.2(a) that the Company is Insolvent

           (a) by reason of Section 1.11(b), the Trustee shall suspend payments 
      to Participants and shall notify Participants of the suspension, and shall
      hold the Trust Fund for the benefit of the General Creditors, and shall
      pay and deliver the entire amount of the Trust Fund only as a court
      competent jurisdiction, or duly appointed receiver or  other person
      authorized to act by such court, may order or direct to make the Trust
      Fund available to satisfy the claims of the General Creditors (payments to
      Participants in accordance with the terms of the Plan may be resumed
      only pursuant to Section 7.4 hereof); or

           (b) by reason of Section 1.11(a), the Trustee shall suspend payments
      to Participants and shall notify Participants of the suspension, and
      shall (i) hold the Trust Fund for the benefit of General Creditors or
      (ii) pay over all or a portion of the Trust Fund to General Creditors if
      directed by the Company or an appropriate judicial forum.

Nothing in this Trust Agreement shall in any way diminish any rights of
Participants to pursue their rights as unsecured creditors of Company with
respect to benefits under the Plan, or otherwise.

7.4  Resumption of Duties after Insolvency.  In the absence of notice of a
Court order to the contrary, the Trustee shall resume all of its duties and
responsibilities under the Trust, including payments to Participants if
otherwise provided for herein, within thirty (30) days of the Trustee's receipt
of a determination from the Company's independent public accounting firm that
the Company is no longer Insolvent.

           (a) Trust Recovery of Payments to Creditors. In the event that
      amounts are paid from the Trust Fund to General Creditors of the Company,
      then as soon as practicable after the Company is no longer Insolvent, the
      Company shall deposit into the Trust Fund a sum to equal to the Funding
      Amount, determined as of the date the Company is no longer Insolvent,
      which date shall be a Valuation Date. The Company (or, after a Change of
      Control, the Company's independent public accountants) shall provide the
      Trustee with written certification of such Funding Amount. If the Funding
      Amount is not paid by the Company within ninety (90) days of the
      Trustee's receipt of such notice, the Trustee shall demand payment and
      the provisions of Section 3.5 shall apply.

           (b) Determination of Payment Amount; Resumption of Payments.
      Provided that there are sufficient assets of the Trust Fund, if Trustee
      discontinues the payment of benefits from the Trust pursuant to Section
      7.3 and subsequently resumes such payments, the first payment following
      such discontinuance shall include the aggregate amount of all payments
      due to Participants under the terms of the Plan for the period of such
      discontinuance, as determined by the Plan Administrator, less the
      aggregate amount of any payments made to Participants by the Company in
      lieu of the payments provided for hereunder during any such period of
      discontinuance. If the Trustee suspends a payment to a Participant under
      this Section, and subsequently makes such payment, the payment shall
      include interest at the rate of interest per annum equal to the prime
      rate as published by NBD Bank for each day from the date of suspension to
      the date of payment, as calculated by the Plan Administrator.

VIII.  RESIGNATION OR REMOVAL OF TRUSTEE


     8.1 Resignation or Removal of Trustee.  The Trustee may resign for any
reason or for no reason and at any time by giving thirty (30) days prior
written notice to the Company (or such shorter notice as may be agreed to by
the Company and the Trustee). Subject to Section 8.2(b) hereof, the Company may
remove the Trustee, for any reason and with or without cause, by giving thirty
(30) days prior written notice to the Trustee (or such shorter notice as may be
agreed to by the Company and the Trustee).

     8.2 Successor Trustee.  In the event of the resignation or removal of a
Trustee, a successor Trustee shall be appointed. Any successor Trustee
appointed pursuant to this Section must be a corporation which is not an
affiliate of the Company and which is authorized under the laws of the United
States or of any state to administer trusts and has at the time of its
appointment total capital and surplus of at least Fifty Million Dollars
($50,000,000). The Company shall give notice of any such appointment to the
retiring Trustee and the successor Trustee. A successor Trustee shall be
appointed in accordance with the following provisions:

           (a) At any time prior to a Change of Control, a successor Trustee
      shall be appointed by the Company. If a Trustee should resign or be
      removed, and the Company does not notify the Trustee of the appointment
      of a successor Trustee within forty-five (45) days of its notice of its
      resignation or removal, then the Company shall be deemed to have failed
      to have appointed a successor Trustee, and the Trustee shall apply to a
      court of competent jurisdiction for appointment of a successor Trustee.

           (b) After the occurrence of a Change of Control, the Trustee who is
      the Trustee on the date of the Change of Control may be removed by the
      Company for three (3) years from the date of the Change of Control. If a
      Trustee resigns or is removed at any time after the date of a Change of
      Control, the Trustee shall apply to a court of competent jurisdiction for
      appointment of a successor Trustee.

Notwithstanding Section 8.1, no resignation by or removal of the Trustee shall
be effective prior to the effective date of the appointment of a successor
Trustee by the Company or a court of competent jurisdiction.

     8.3 Duties of Retiring and Successor Trustees.  In the event of the
resignation or removal of a Trustee, the retiring Trustee shall within thirty
(30) days after the effective date of resignation or removal furnish to the
successor Trustee and the Company a final accounting of its administration of
the Trust. A successor Trustee shall succeed to the right and title of the
predecessor Trustee in the assets of the Trust Fund and the retiring Trustee
shall deliver the property comprising the assets of the Trust Fund (less any
unpaid fees and expenses of the retiring trustee) to the successor Trustee,
together with any instruments of transfer, conveyance, assignment, and further
assurance as the successor Trustee may reasonably require. All of the
provisions of the Trust set forth herein with respect to the Trustee shall
relate to each successor Trustee with the same force and effect as if such
successor Trustee had been originally named as the Trustee hereunder. To the
extent permitted by law, neither the Trustee nor the successor Trustee shall be
liable for any act or failure to act, and shall not be required to examine the
accounts, records, or acts of the other.

     8.4 Reserved.

IX.  AMENDMENT AND TERMINATION OF TRUST


     9.1 Amendment. Except as otherwise provided in Section 2.3 of this Trust,
the Trust may be amended (but may not be not revoked unless all of the
Company's obligations with respect to the Plan have been satisfied) in writing
from time to time by delivery to the Trustee of such amendment executed by the
Company, which amendment shall include the effective date of such amendment.
Any amendment of the Trust may be made:

           (a) prior to a Change of Control, without limitation and in any
      manner and effective as of any date, including a retroactive effective
      date, if accompanied by the written certification that no Change of
      Control has occurred;

           (b) after a Change of Control, only if a period of three (3) years
      has elapsed since the Change of Control, and either:

                 (1) such amendment is accompanied by the specific written
            consent to the amendment by Participants whose actuarial interests
            under the Plan, computed by the Company's independent public
            accountants as of the effective date of such amendment, represent
            at least 51% of the total of all actuarial interests under the
            Plan; or


                                     - 27 -


 
<PAGE>   33


                 (2) such amendment is accompanied by the opinion of legal
            counsel satisfactory to the Trustee that the amendment is necessary
            for the purpose of conforming the Trust to any present or future
            federal or state law (including revenue laws) relating to trusts of
            this or similar nature, as such laws may be amended from time to
            time, and a certification that a copy of such notice and opinion of
            counsel has been delivered to each Participant.

No amendment shall conflict with the terms of the Plan subject to amendment,
and no amendment may reduce the "Funding Amount" or the contribution
requirements of Article III to less than 50% of the actual benefit obligation
on the books of the Company; provided such amendment shall be effective prior
to a Potential Change of Control or a Change of Control. No amendment shall
operate to change the duties and liabilities of the Trustee without its
consent, or make the Trust revocable after it has become irrevocable in
accordance with Section 2.3 hereof unless the Company has satisfied all
obligations it may have with respect to the Plan as of the date of such
amendment. The Company and the Trustee shall execute such amendments of the
Trust as shall be necessary to give effect to any amendment made in accordance
with this Section.

     9.2 Termination.  After all assets of the Trust Fund have been distributed
by the Trustee to the Participants or their Beneficiaries in accordance with
Article VI, the Trustee shall render an accounting, which shall be the final
accounting, in the manner provided for in Section 4.3. Upon acceptance of the
accounting by  the Company, any assets remaining in the Trust Fund, after
deduction of such reasonable amount for compensation and expenses as provided
for in Section 10.7, shall be returned to the Company in the manner provided in
Section 6.8, and the Trust shall terminate thereupon. The Trust and all the
rights, titles, powers, duties, discretions and immunities imposed on or
reserved to the Trustee and the Company, shall continue in effect until all
assets of the Trust Fund have been distributed as provided herein.

     9.3 Reserved.

X. GENERAL PROVISIONS

     10.1 Coordination with Plan.  The responsibilities of the Trustee shall be
governed solely by the terms of this Trust Agreement.

     10.2 Litigation.  In any action or proceeding regarding the Trust, the
Company, any assets of the Trust Fund, or the administration of the Trust, any
creditors who are not parties to such action or proceedings and any other
persons having or claiming to have a beneficial interest in the Trust shall not
be necessary parties and shall not be entitled to any notice of process. Any
final judgment which is not appealed or appealable and which may be entered in
any such action or proceeding shall be binding and conclusive on the parties
hereto and all persons having or claiming to have a beneficial interest in the
Trust. Acceptance by a creditor of assets of the Trust Fund shall constitute a
release of an equal amount of any obligations of the Company to such creditor.

     10.3 Trustee's Action Conclusive.  The Trustee's exercise or non-exercise
of its powers and discretion in good faith shall be conclusive on all persons.
No one other than the Company shall be obliged to see to the application of any
money paid or property delivered to the Trustee. The certificate of the Trustee
that it is acting according to this Trust will fully protect all persons
dealing with the Trustee.

     10.4 No Guarantee or Responsibility.  Notwithstanding any other provision  
of this Trust to the contrary, the Trustee does not guarantee payment of any
amount which may become due and payable to a Participant. The Trustee shall have
no responsibility for the disclosure to Participants regarding the terms of the
Plan or of this Trust, or for the validity thereof. The Trustee shall not be
responsible for administrative functions under the Plan and shall have only such
responsibilities under this Trust Agreement as specifically set forth herein.
The Trustee will be under no liability or obligation to anyone with respect to
any failure on the part of the Company, the Plan Administrator, the Company's
independent public accounting firm, an Investment Manager, or a Participant to
perform any of their respective obligations under the Plan or this Trust. The
Trustee shall be fully protected in relying upon any notice or direction
provided to it from any party in connection with the Trustee's duties hereunder
which the Trustee in good faith believes to be genuine, and executed and 
delivered in accordance with this Trust. Nothing in this Trust shall be
construed as requiring the Trustee to make any payment in excess of the amounts
held in the Trust Fund at the time of such payment or otherwise to risk or
expend its own funds.

     10.5 Liabilities Mutually Exclusive.  Each of the Trustee and the Company
shall be responsible only for its own acts or omissions.

     10.6 Indemnification.  The Company agrees to indemnify to the extent
permitted by law the Trustee and hold it harmless against Trustee's costs,
expenses and


                                     - 29 -

 
<PAGE>   35

liabilities (including, without limitation, attorneys' fees and
expenses) arising out of or in connection with the performance of the Trustee's
duties arising hereunder (but excluding costs arising as a result of the
Trustee's bad faith or gross negligence in the performance of its
responsibilities hereunder), and to be primarily liable for such payments. If
the Company does not pay such costs, expenses and liabilities in a reasonably
timely manner, Trustee may obtain payment from the Trust. This Section shall
survive the termination of the Trust.

     10.7 Expenses and Compensation.  The Trustee shall be paid compensation by
the Company in an amount agreed to by the Company and the Trustee. The Trustee
shall be reimbursed by the Company for reasonable expenses incurred by it in
the management and administration of this Trust Agreement, including the
reasonable compensation of the Trustee's counsel and other agents; and if the
Trustee is not timely reimbursed with respect to amounts due pursuant to this
Section 10.7 (or in the case of expenses to be incurred pursuant to Section 3.5
hereof), the Trustee may charge such amounts against the Trust Fund. Any
compensation or expenses so agreed upon or otherwise payable not paid by the
Company on a timely basis may be charged to the Trust Fund no more frequently
than quarter-annually upon notice to the Company.

     10.8 Reserved.

     10.9 Notice.  Any notice to the Trustee or to the Company required or
permitted under this Trust shall be duly and properly given and delivered if
sent by certified United States mail, return receipt requested, to the Trustee

or invalid, such illegality or invalidity shall not affect the remaining
provisions of this Trust, which shall be construed and enforced as if such
illegal or invalid provisions had never been inserted herein.

     10.17 Applicable Law. The Trust shall be governed by and construed in
accordance with the laws of the State of Michigan with respect to the Company's
