                           THE DETROIT EDISON COMPANY

                           IRREVOCABLE GRANTOR TRUST

                         FOR THE DETROIT EDISON COMPANY

                            SAVINGS REPARATION PLAN


         THIS TRUST AGREEMENT is made this 24th day of July, 1995, as restated
in its entirety effective January 1, 1996, by and between The Detroit Edison
Company, a Michigan corporation, and The Northern Trust Company, an Illinois
corporation, of Chicago, Illinois ("Trustee"), and any successor provided for
in the Trust hereby evidenced, as Trustee.

WITNESSETH THAT:

         WHEREAS, the Company has established and maintains the Savings
Reparation Plan ("Plan"), an unfunded benefit plan, a copy of which is attached
hereto as Exhibit A, for the benefit of certain Company Executives listed on
Exhibit B hereto, which Exhibits may be amended from time to time by the
Company prior to a potential Change of Control and/or Change of Control, and
without the Trustee's consent; and

         WHEREAS, the Company has incurred and expects to continue to incur
liabilities pursuant to the terms of the Plan, and wishes to establish an
irrevocable trust by placing assets in trust, subject to the claims of the
Company's creditors in the event the Company becomes Insolvent, to pay benefits
under the Plan or to be applied as otherwise provided for herein; and

         WHEREAS, it is the intention of the Company that amounts transferred
to the Trust and the earnings thereon shall be used by the Trustee, subject to
the claims of the Company's creditors in the event the Company becomes
Insolvent, to satisfy the liabilities of the Company in accordance with the
provisions hereof; and, upon satisfaction of all liabilities of the Company
with respect to all Participants (and their Beneficiaries, if applicable), the
assets, if any, remaining in the Trust shall revert to the Company; and

         WHEREAS, the Company intends that the existence of the Trust shall not
alter the characteristics of the Plan as an unfunded plan maintained primarily
for the purpose of providing deferred compensation for a select group of
management and/or highly-compensated employees, and shall not be construed to
provide income for federal income tax purposes to a Participant (or his or her
Beneficiary) prior to the actual payment of benefits under the Plans; and

         WHEREAS, the Trustee has agreed to serve as trustee of such trust;

NOW, THEREFORE, in consideration of the mutual undertakings of  the Company and
the Trustee, the parties do hereby establish the Trust, and agree that the
Trust shall be comprised, held, and disposed of as follows:

         any successor provisions, whether or not the Company is then subject
         to such reporting requirement; or

         (b)     any "person" (as such term is used in Sections 13(d) and 14(d)

                          such change, or

                          same proportionate ownership of common stock of the
                          surviving corporation immediately after the merger,
                          or

                 (2)      any sale, lease, exchange, or other transfer (in one

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.

<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

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

specific records as shall be agreed upon in writing between the Company and the

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,

         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:

         instructions;

         conversion of the policy from a different form) other than to a
         successor Trustee, or to loan to any person the proceeds of any
         borrowing against such policy. Notwithstanding the preceding sentence,
         the Trustee may loan to the Company the proceeds of any borrowing

                 (h)      to furnish the Company with such information for tax

assets of the Trust Fund subject to the Investment Manager(s). After it
receives written notice of such appointment, the Trustee shall have no
obligation or responsibility for those investment duties which are allocated to
an Investment Manager. An Investment Manager so appointed pursuant to this
paragraph shall be either a registered investment adviser under the Investment
Advisers Act of 1940, a bank, as defined in said Act, or an insurance company
qualified to

manage, acquire and  dispose of the assets of the Plans under the laws of more
than one state of the United States. Any such Investment Manager shall
acknowledge to the Company in writing that is accepts such appointment. The
Trustee shall not be liable for any loss or diminution of any assets managed by
an Investment Manager, including without limitation, any loss or diminution
caused by any action or inaction taken or omitted by it at the direction of an
Investment Manager. In addition, the Trustee shall not be liable for the
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.

         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 -

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.

<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.

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.

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.

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.

<PAGE>   34


         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
