               is not the continuing or surviving corporation or pursuant to

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 employee 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 acquires the right to receive payment(s) under the Plan, any
     such right shall be





                                     - 8 -
<PAGE>   14

     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
     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

<PAGE>   17


     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 -

     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 or approval given by Company which is contemplated by, and in
conformity with, the terms of the Trustee's responsibilities under this Trust,
and is given in writing by Company. The responsibility for maintenance of
individual benefit records shall be retained by the Company, and may be
delegated to such person or entity as the Company may employ from time to time.
Except as otherwise provided herein, the Trustee shall have, without exclusion,
all powers conferred on trustees by law and, without limiting the foregoing,
shall have the following administrative powers, rights, and duties in addition
to those provided elsewhere in this Trust:

          (a)  to manage, sell, insure, and otherwise deal with all assets held
     by the Trustee on such terms and conditions as the Trustee shall decide;
     provided however, that if the Company delivers written instructions to the
     Trustee, the Trustee shall follow such instructions;

          (b)  when directed by the Company or requested by a Participant
     pursuant to Article VI, to make payments from the Trust Fund to
     Participants and, when required by Article VII, to make payments from the
     Trust Fund to General Creditors entitled to payments thereunder;

          (c)  except as provided in Article VI and Article VII, to waive,
     modify, reduce, compromise, release, contest, submit to arbitration, or
     settle or extend the time of payment of any claims, debts, damages, or
     demands of any nature in favor of or against the Trustee or all or any
     part of the Trust Fund;

          (d)  to retain any disputed property until an appropriate final
     adjudication or release is obtained, and to represent the Trust in, or
     commence or defend, any litigation the Trustee considers in its discretion
     necessary in connection with the Trust Fund;





                                     - 13 -
<PAGE>   19


          (e)  to withhold, if the Company so directs, all or any part of any
     payment required to be made hereunder as may be necessary and proper to
     protect the Trustee or the Trust Fund against any liability or claim on
     account of any estate, inheritance, income or other tax or assessment
     attributable to any amount payable hereunder, and to discharge any such
     liability with any part or all of such payment so withheld in accordance
     with Section 6.7;

          (f)  to maintain records reflecting all receipts and payments under
     this Trust and such other records as the Company may specify and to which

          (r)  generally to do all acts, whether or not expressly authorized,
     that the Trustee deems necessary or desirable for the protection of the
     Trust Fund, and to carry out the purposes of the Trust.

     5.3  Investment Managers.  The Company may appoint one or more Investment
Managers to direct the investment of any part or all of the assets of the Trust
Fund by the Trustee. Appointment of an Investment Manager shall be made by
written notice to the Investment Manager(s) and to the Trustee, which notice
shall specify those powers, rights, and duties of the Trustee under this Trust
that are allocated to the Investment Manager(s) and the portion of the assets
of the Trust Fund subject to the Investment Manager(s).  After it receives

diversification of any assets managed by Investment Managers of the Company,
each of which shall be solely the responsibility of the Company. An Investment
Manager may resign at any time upon written notice to the Trustee and the
Company. The Company may remove an Investment Manager at any time by written
notice to the Investment Manager and the Trustee.

     The Company may by written notice to the Trustee assume investment
responsibility for any portion or all of the Trust assets. The Trustee shall
have no responsibility for any investments or review of such investments and
shall act with respect to such assets only as directed by the Company.

     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
Participant or other General Creditors in accordance with Article VI or Article
VII. All rights associated with assets of the Trust shall be exercised by
Trustee or the person designated by Trustee, and shall in no event be
exercisable by or rest with Participants.

VI.  PAYMENTS FROM THE TRUST

     6.1  Obligation of Trustee to Make Payments to Participants.  The
Trustee's obligation to distribute to any Participant out of the assets of the
Trust Fund shall be limited to payment at such times and in such amounts as are
properly 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 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.





                                     - 23 -
<PAGE>   29


          (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.





                                     - 24 -
<PAGE>   30


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

         10.16       Severability. If any provision of this Trust is held to be
illegal or invalid, such illegality or invalidity shall not affect the
remaining provisions of this Trust, which shall be construed and enforced as if

construed in accordance with the laws of the State of Michigan with respect to
the Company's obligations and in accordance with the laws of the State of
