                             SUN COMPANY, INC.
                 DEFERRED COMPENSATION AND BENEFITS TRUST


     TRUST AGREEMENT (the "Trust"), dated February 1, 1996, by and between
Sun Company, Inc., a Pennsylvania corporation (the "Company"), Mellon Bank,
N.A. (the "Trustee") and Towers Perrin (the "Recordkeeper").

     WHEREAS, the Company (or certain of its subsidiaries) is or may become
obligated under certain employee benefit plans or agreements to make
payments to certain persons who at any time prior to the occurrence of a
"Change in Control" of the Company (as defined herein) were employees of
the Company (or certain of its subsidiaries) (the "Executives") and their
beneficiaries; and

     WHEREAS, in order to assure that future payment of such amounts would
not be improperly withheld in the event of a Change in Control of the
Company, the Company has previously established a trust (hereinafter called
"Trust") the assets of which are subject to the claims of Company's
creditors in the event of Company's Insolvency (as herein defined in
section 5 (a)) until paid to Plan participants and their beneficiaries in
such manner and at such times as specified in the Plans; and

     WHEREAS, the Company has determined to amend and restate such Trust in
its entirety, effective as of February 1, 1996, in order to meet the
requirements established in Revenue Procedure 92-64 of the United States
Internal Revenue Service; and 

     WHEREAS, it is the intention of the parties that this Trust, as so
amended and restated, shall constitute an unfunded arrangement and shall
not affect the status of the Plans as unfunded plans maintained to provide
deferred compensation for a select group of management or highly
compensated employees for purposes of Title I of the Employee Retirement
Income Security Act of 1974;

     WHEREAS, it is the intention of Company to make contributions to such
amended and restated Trust to provide itself with a source of funds to
assist it in the meeting of its liabilities under the Plans;

     NOW, THEREFORE, the parties do hereby amend and restate the Trust in
its entirety, and agree that such amended and restated Trust shall be
comprised, held and disposed of as follows:

 
2

Section 1.  The Plans

(a)  The plans and/or agreements that are subject to this Trust
     (collectively referred to as the "Plans") are listed on Appendix A
     hereto.  Prior to a Change in Control of the Company, the Compensation
     Committee of the Board of Directors of the Company (the "Compensation
     Committee") may from time to time designate additional plans and/or
     agreements that are subject to this Trust (collectively referred to as
     the "Plans") or delete any Plan from this Trust.

(b)  The Company (or certain of its subsidiaries) shall continue to be
     liable to the Executives to make all payments required under the terms
     of the Plans to the extent such payments have not been made pursuant
     to this Trust.  Distributions made from the Trust to or for Executives
     in respect of the Plans pursuant to Section 4 hereof, shall, to the
     extent of such distributions, satisfy the Company's (or certain of its
     subsidiaries') obligation to pay benefits to such Executives under the
     Plans.

Section 2.  Establishment of Trust

(a)  Company hereby deposits with Trustee in trust the sum of $100 in cash
     which shall become the principal of the Trust to be held, administered
     and disposed of by Trustee as provided in this Trust Agreement.  

(b)  The Trust hereby established is revocable by Company; it shall become
     irrevocable upon a Change of Control, as defined herein.

(c)  The Trust is intended to be a grantor trust, of which Company is the
     grantor, within the meaning of subpart E, part I, subchapter J,
     chapter 1, subtitle A of the Internal Revenue Code of 1986, as
     amended, and shall be construed accordingly.

(d)  The principal of the Trust, and any earnings thereon shall be held
     separate and apart from other funds of Company and shall be used
     exclusively for the uses and purposes of Plan participants and general
     creditors as herein set forth.  Plan participants and their
     beneficiaries shall have no preferred claim on, or any beneficial
     ownership interest in, any assets of the Trust.  Any rights created
     under the Plans and this Trust Agreement shall be mere unsecured
     contractual

 
3

     rights of Plan participants and their beneficiaries against Company. Any
     assets held by the Trust will be subject to the claims of Company's general
     creditors under federal and state law in the event of Insolvency, as
     defined in Section 5(a) herein.

(e)  In the event of a Potential Change in Control of the Company, an additional
     amount of cash (or property acceptable to the Trustee having a fair market
     value equal to such amount, or some combination thereof), representing the
     sum of the amounts, determined as provided below, plus an amount equal to
     5% of that amount to provide for expenses and other costs of maintaining
     the Trust (collectively, the "Required Funding Amount"), shall be delivered
     not later than 30 days after the occurrence of a Potential Change in
     Control of the Company (as defined in Section 13(e) hereof).

(f)  In the event the Compensation Committee designates additional Plans that
     are subject to this Trust and/or Plans subject to this Trust are amended
     after a Potential Change in Control of the Company, the Treasurer shall,
     unless the Trust Corpus shall theretofore have been released pursuant to
     Section 6(a) hereof, recalculate the Required Funding Amount. If the amount
     so calculated exceeds the fair market value of the assets then held in
     trust, the Company shall promptly (and in no event later than 30 days from
     the date of such recalculation) pay to the Trustee an amount of cash (or
     property acceptable to the Trustee having a fair market value equal to such
     amount, or some combination thereof) equal to such excess. If the Required
     Funding Amount so calculated is less than the fair market value of the
     assets held in trust, the Trustee shall retain such difference.

(g)  If, subsequent to a Control Transaction which has not been expressly
     approved by at least a majority vote of the Continuing Directors, there is
     a Change in Control, Company shall, as soon as possible, but in no event
     longer than one (1) day following the Change in Control, as defined herein,
     make an irrevocable contribution to the Trust in an amount that is
     sufficient to pay each Plan participant or beneficiary the benefits to
     which Plan participants or their beneficiaries would be entitled pursuant
     to the terms of the Plans as of the date on which the Change of Control
     occurred. This Required Funding Amount shall be determined in a way that
     will provide the Trust with sufficient assets, taking into consideration
     Section 3(e), to pay all benefits accrued by the Executives through the
     date of the Change in Control of the Company under the terms of the Plans
     in effect on such date. The Company agrees not to challenge the Treasurer's
     calculation of the required Funding Amount upon and after a Change in
     Control of the Company.


 
4

(h)  The Company agrees to pay interest on any delinquent payment of the
     Required Funding Amount from the date of a Change in Control of the
     Company, based upon the daily average of the prime rate charged by the
     Trustee.

(i)  In determining the Required Funding Amount with respect to any payment
     or series of payments expected to be due more than one year after the
     date as of which the required Funding Amount is to be determined, the
     present value of such payment or series of payments shall be
     calculated by using a discount rate equal to one percentage point less
     than the then lowest annual yield to maturity on United States
     Treasury obligations having then remaining maturities approximately
     equal to the maturity of the payment or payments being valued.

(j)  Payment by the Company pursuant to Section 2(a) and 2(e) hereof shall
     be accompanied by a schedule delivered to the Recordkeeper (as
     described in Section 4(d) of the individual Plans for whose accounts
     such payment is being made, which schedule sets forth the amounts
     delivered in respect of each of the Plans.  The Recordkeeper shall
     maintain in an equitable manner an account for each Plan (the
     "Account").  Each Account shall consist of contributions to and
     payments from the Trust Corpus which are allocable to the Plan, and
     earnings thereon, less disbursements therefrom attributable to the
     interest of the Plan in the entire Trust Corpus.

Section 3.  Investment Authority

(a)  As used herein, the term "Trust Corpus" shall mean the amounts
     delivered to the Trustee pursuant to the terms hereof, less amounts
     distributed from the Trust pursuant to the terms hereof,  plus all
     income earned by the Trust, in whatever form held or invested as
     provided herein.

(b)  Trustee may invest in securities (including stock or rights to acquire
     stock) or obligations issued by Company.  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 Plan participants.  Subject to investments guidelines agreed to
     in writing from time to time by the Trustee and the Benefit Plans
     Investment Committee until a Change in Control occurs, the Trustee
     shall have the following powers and discretion in addition to those
     conferred by law:

 
5

     (1)  To invest and reinvest the Trust Corpus in such stocks (of any
          classification, including common and preferred stocks), bonds, or
          other property (real, personal or mixed) and interests in
          investment companies and investment trusts;

     (2)  To sell, exchange, convey, transfer or dispose of, and also to
          grant options with respect to, any property, whether real or
          personal, at any time held by it by private contract or by public
          auction, for cash or upon credit, or partly for cash and partly
          upon credit, as the Trustee may deem best, and no person dealing
          with the Trustee shall be bound to see to the application of the
          purchase money or to inquire into the validity, expediency or
          propriety of any such sale or other disposition;

     (3)  To acquire, hold and dispose of any real estate, at such time, in
          such manner and upon such terms as the Trustee may deem
          advisable; to retain, manage, operate, repair, improve,
          partition, mortgage or lease for any term or terms of years any
          such real estate, or to exchange all or any part thereof for
          other real estate, upon such terms and conditions as the Trustee
          deems proper, using other trust assets for any of such purposes
          if deemed advisable;

     (4)  To compromise, compound and settle any debt or obligation due to
          or from the Trust and to reduce the rate of interest thereon, to
          extend or otherwise modify, or to foreclose upon default or
          otherwise enforce or act with respect to any such obligation as
          the Trustee may deem advisable;

     (5)  With respect to stocks, bonds or securities excluding stocks,
          bonds or securities of the Company, to vote, in person or by
          general or limited proxy, any stocks or other securities at any
          time held in the Trust Corpus, at any meeting of stockholders or
          security holders, in respect to any business which may come
          before the meeting; to exercise any options appurtenant to any
          stocks, bonds or other securities for the conversion thereof into
          other stocks, bonds or securities; to exercise or sell any
          conversion or subscription rights appurtenant to any stocks,
          bonds or other securities at any time held in the Trust Corpus,
          and to make any and all necessary payments therefor; to join in,
          and to approve, or to dissent from and to oppose, any

 
6

          corporate act or proceeding, including any reorganization,
          recapitalization, consolidation, merger, dissolution,
          liquidation, sale of assets or other action by or plan in respect
          of corporations or properties, the stocks or securities of which
          may at any time be held in the Trust Corpus; to deposit with any
          committee or depository, pursuant to any plan or agreement of

          payment from the Trust Corpus of any charges or assessments
          imposed by the terms of any such plan or agreement; 

     (6)  With respect to stocks, bonds or securities of the Company, the
          Trustee shall exercise the powers under Section 3(b)(5) at its
          discretion.

     (7)  To accept and hold any securities or other property received by
          it under the provisions of any of the subdivisions of this
          Article whether or not the Trustee would be authorized hereunder
          then to invest therein;

     (8)  To borrow money upon such terms and conditions at the Trustee
          shall deem advisable to carry out the purposes of the Trust and
          to pledge securities or other property of the Trust Corpus in
          repayment of any such loan;

     (9)  To enforce any right, obligation or claim and in general to
          protect in any way the interest of the Trust Corpus, either
          before or after default, and in case the Trustee shall, in its
          discretion, consider such action for the best interest of the
          Trust Corpus, to abstain from the enforcement of any right,
          obligation or claim and to abandon any property, whether real or
          personal which at any time may be held by the Trustee;

     (10) To make, execute, acknowledge and deliver any and all deeds,
          leases, assignments transfers, conveyances and any and all other
          instruments necessary or appropriate to carry out any powers
          herein granted;

     (11) To cause any investments from time to time held by it hereunder
          to be registered in, or transferred into, its name as Trustee or
          the name of its nominee or nominees, and with or without
          designation of fiduciary capacity, or to retain any investments
          unregistered or in form permitting transfer by delivery, but the
          books and records of the Trustee shall at all times show that all
          such investments are part of the Trust Corpus;

 
7

     (12) To hold any part or all of the Trust Corpus uninvested; and

     (13) To do all acts which may be necessary or proper and to exercise
          any and all of the powers of the Trustee under this Agreement
          upon such terms and conditions as to the Trustee may seem in the
          best interests of the Trust Corpus.

(c)  Upon and after a Change in Control, the Trustee shall use its good
     faith efforts to invest or reinvest all or such part of the Trust
     Corpus as it believes prudent under the circumstances (taking into
     account, among other things, anticipated cash requirements for the
     payment of benefits under the Plans communicated to the Trustee by the
     Recordkeeper) solely in direct obligations of the United States of
     America or agencies thereof or obligations unconditionally and fully
     guaranteed as to principal and interest by the United States of
     America, and with respect to such investments the Trustee shall have
     the powers and discretion set forth in Section 3(b) in addition to
     those conferred by law; provided, however, that the Trustee shall not
     be liable for any failure to maximize the income earned on that
     portion of the Trust Corpus as is from time to time invested or
     reinvested as set forth under Section 3(c), nor for any loss of income
     due to liquidation of any investment which liquidation is necessary to
     make payments or to reimburse expenses under the terms of this Trust.

(d)  All losses of income or principal in respect of, and expenses
     (including taxes and, as provided in Section 9   hereof, any expenses
     of the Trustee) charged against, the Trust Corpus shall be for the
     account of the Company and the Company shall be obligated to reimburse
     the Trust Corpus for any loss in principal amount of, or expense
     charged against, the Trust Corpus except to the extent that such
     amounts have been applied to reduce amounts payable by the Company (or
     certain of its subsidiaries) pursuant to Section 4 hereof.  The
     Trustee shall promptly notify the Company in writing of the amount of
     such reimbursement.  The Company agrees that, upon receipt of such
     notice, it will deliver to the Trustee to be held in the Trust an
     amount in cash equal to any reimbursement amount specified by the
     Trustee, together with interest from the date of receipt of such
     notice based upon the daily average of the prime rate charged by the
     Trustee.

 
8

(e)  Company shall have the right at any time, and from time to time in its
     sole discretion, to substitute assets of equal fair market value for
     any asset held by the Trust.  This right is exercisable by Company in
     a nonfiduciary capacity without the approval or consent of any person
     in a fiduciary capacity.  

Section 4.  Payments to Plan Participants and Their Beneficiaries

(a)  By its acceptance of this Trust the Trustee hereby agrees to the
     designation by the Company of Towers Perrin as its recordkeeper
     ("Recordkeeper") under this Trust.  It is recognized that the Trustee
     shall have no responsibility hereunder for the continued retention of
     the Recordkeeper and/or any responsibility assigned to said
     Recordkeeper or its performance thereof.  Upon and after a Change in
     Control of the Company, the Trustee shall have the sole authority to
     retain, dismiss or appoint the Recordkeeper for the Trust on such
     terms and conditions as the Trustee deems appropriate.  The Company
     shall pay or reimburse the Trustee for all fees and expenses of the
     Recordkeeper.

(b)  Except for the records dealing solely with the Trust Corpus and its
     investment, which shall be maintained by the Trustee, the Recordkeeper
     shall maintain all the records contemplated by this Agreement,
     including the maintenance of the separate Accounts of each Plan under
     this Trust and the maintenance of Executives' Plan interests.  The
     Recordkeeper shall also be responsible for information with respect to
     payments to Executives and shall perform such other duties and
     responsibilities as the Trustee determines are necessary or advisable
     to achieve the objectives of this Trust.

(c)  Upon the establishment of this Trust or as soon thereafter as practicable,
     the Company shall furnish to the Recordkeeper all the information necessary
     to determine the benefits payable to or with respect to each Executive in
     each Plan, including any benefits payable after the Executive's death and
     the recipient of same. The Company shall regularly, at least annually,
     furnish revised up-dated information to the Recordkeeper. In the event the
     Company refuses or neglects to provide updated Executive information, as
     contemplated herein, the Recordkeeper shall be entitled to rely upon the
     most recent information furnished to it by the Company.

 
9

(d)  The Recordkeeper, on behalf of the Company, shall deliver to Trustee a
     schedule (the "Payment Schedule") that indicates the amounts payable in
     respect of each Plan participant (and his or her beneficiaries), that
     provides a formula or other instructions acceptable to Trustee for
     determining the amounts so payable, the form in which such amount is to be
     paid (as provided for or available under the Plans), and the time of
     commencement for payment of such amounts. Except as otherwise provided
     herein, Trustee shall make payments to the Plan participants and their
     beneficiaries in accordance with such Payment Schedule. The Trustee shall
     make provision for the reporting and withholding of any federal, state or
     local taxes that may be required to be withheld with respect to the payment
     of benefits pursuant to the terms of the Plans and shall pay amounts
     withheld to the appropriate taxing authorities or determine that such
     amounts have been reported, withheld and paid by Company.

(e)  The entitlement of a Plan participant or his or her beneficiaries to
     benefits under the Plans shall be determined by the Recordkeeper, on
     behalf of the Company, and any claim for such benefits shall be
     considered and reviewed under the procedures set out in the Plans and
     this Trust Agreement.

(f)  The Company may make payment of benefits directly to Plan participants or
     their beneficiaries as they become due under the terms of the Plans.
     Company shall notify Trustee and Recordkeeper of its decision to make
     payment of benefits directly prior to the time amounts are payable to
     participants or their beneficiaries. In addition if the principal of the
     Trust, and any earnings thereon, are not sufficient to make payments of
     benefits in accordance with the terms of the Plans, Company shall make the
     balance of each such payment as it falls due. Trustee shall notify Company
     where principal and earnings are not sufficient.

(g)  The Recordkeeper shall notify the Executive or the beneficiary of a
     deceased Executive that Executive's benefits under a Plan have become
     payable.  Such notice shall include the amount of such benefits, the
     manner of payment and the name, address and social security number of
     the Executive.  

 
10

(h)  All benefits payable from the Trust Corpus to an Executive or his
     beneficiary under a Plan shall be paid solely from the Account of such
     Plan. Upon the satisfaction of all liabilities under a Plan in respect of
     Executives under a Plan, the Recordkeeper shall prepare a certification to
     the Trustee showing the balance, if any, remaining in the Account for such
     Plan. Such balance shall thereupon be reallocated ratably by the
     Recordkeeper to the Accounts of other Plans covered by this Agreement
     (including Accounts which may have previously been reduced to a zero
     balance) in the ratio that liabilities in respect of each such Plan bear to
     the total liabilities of all such Plans. Upon the satisfaction of all
     liabilities of the Company under all Plans, the Recordkeeper shall prepare
     a certification to the Trustee and the Trustee shall thereupon distribute
     the Trust Corpus to the Company. The Trustee and the Recordkeeper shall
     have no responsibility for determining whether any Executive or beneficiary
     has died and shall be entitled to rely upon information furnished by the
     Company.

(i)  Except as otherwise provided herein, in the event of any final
     determination by the Internal Revenue Service or a court of competent
     jurisdiction, which determination is not appealable or with respect to
     which the time for appeal has expired, or the receipt by the Trustee
     of a substantially unqualified opinion of tax counsel selected by the
     Trustee, which determination determines, or which opinion opines, that
     the Executives or any particular Executive, is subject to federal
     income taxation on amounts held in Trust hereunder prior to the
     distribution to the Executives or Executive of such amounts, the
     Trustee, on receipt by the Trustee, of such opinion or notice of such
     determination, shall pay to each Executive the portion of the Trust
     Corpus includible in such Executive's federal gross income.

(j)  The Company agrees to indemnify and hold harmless the Recordkeeper
     from and against any and all damages, losses, claims, fees or expenses
     as incurred (including expenses of investigation and fees or expenses
     as incurred (including expenses of investigation and fees and
     disbursements of counsel to the Recordkeeper) arising out of or in
     connection with the performance by the Recordkeeper of its duties
     hereunder.  Any amount payable to the Recordkeeper under paragraph (a)
     of this Section 4 or this paragraph (j) and not previously paid by the
     Company shall be paid by the Company promptly upon demand therefore by
     the Trustee or, if not paid by the Company within 30 days of the
     Trustee's demand, from the Trust Corpus.  In the event that payment is
     made hereunder to the Recordkeeper from the Trust Corpus,

 
11

     the Trustee shall promptly notify the Company in writing of the amount of
     such payment. The Company agrees that, upon receipt of such notice, it will
     deliver to the Trustee to be held in the Trust an amount in cash equal to
     any payments made from the Trust Corpus to the Trustee pursuant to
     paragraph (a) of this Section 4 or this paragraph (j), together with
     interest from the date of receipt of such notice based upon the daily
     average of the prime rate charged by the Trustee. The failure of the
     Company to transfer any such amount shall not in any way impair the
     Recordkeeper's right to indemnification, reimbursement and payment pursuant
     to paragraph (a) of this Section 4 or this paragraph (j).

(k)  The Recordkeeper may resign and be discharged from its duties hereunder at
     any time by giving notice in writing of such resignation to the Company, or
     if a Change in Control shall previously have occurred, the Trustee,
     specifying a date (not less than 30 days after the giving of such notice)
     when such resignation shall take effect. Promptly after such notice, the
     Company, or if a Change in Control shall previously have occurred, the
     Trustee, shall appoint a successor recordkeeper, such recordkeeper to
     become Recordkeeper hereunder upon the resignation date specified in such
     notice. If the Company or the Trustee is unable to appoint a successor
     recordkeeper within 60 days after such notice, the Recordkeeper shall be
     entitled, at the expense of the Company, to petition a United States
     District Court or any court of competent jurisdiction in the state in which
     the Recordkeeper maintains its principal place of business to appoint its
     successor. The Recordkeeper shall continue to serve until its successor
     accepts the responsibility of recordkeeper. The Company, or if a Change in
     Control shall previously have occurred, the Trustee, may at any time
     substitute a new recordkeeper by giving 15 days notice thereof of the
     Recordkeeper then acting. In the event of such removal or resignation, the
     Recordkeeper shall provide its successor with the records and information
     in its possession relating to the performance of its duties under this
     Trust.

Section 5.  Trustee Responsibility Regarding Payments to Trust Beneficiary
When Company Is Insolvent.

(a)  Trustee shall cease payment of benefits to Plan participants and their
     beneficiaries if the Company is Insolvent.  Company shall be
     considered "Insolvent" for purposes of this Trust Agreement if (i)
     Company is unable to pay its debts as they become due, or (ii) Company
     is subject to a pending proceeding as a debtor under the United States
     Bankruptcy Code.

 
12

(b)  At all times during the continuance of this Trust, as provided in
     Section 1(D) hereof, the principal and income of the Trust shall be
     subject to claims of general creditors of Company under federal and
     state law as set forth below.

     (1)  The Board of Directors and the Chief Executive Officer of Company
          shall have the duty to inform Trustee in writing of Company's
          insolvency.  If a person claiming to be a creditor of Company
          alleges in writing to Trustee that Company has become Insolvent,
          Trustee shall determine whether Company is Insolvent and, pending
          such determination, Trustee shall discontinue payment of benefits
          to Plan participants or their beneficiaries.

     (2)  Unless Trustee has actual knowledge of Company's insolvency, or
          has received notice from Company or a person claiming to be a
          creditor alleging that Company is Insolvent, Trustee shall have
          no duty to inquire whether Company is Insolvent.  Trustee may in
          all events rely on such evidence concerning Company's solvency as
          may be furnished to Trustee and that provides Trustee with a
          reasonable basis for making a determination concerning Company's
          solvency.

     (3)  If at any time Trustee has determined that Company is Insolvent,
          Trustee shall discontinue payments to Plan participants or their
          beneficiaries and shall hold the assets of the Trust for the
          benefit of Company's general creditors.  Nothing in this Trust
          Agreement shall in any way diminish any rights of Plan
          participants or their beneficiaries to pursue their rights as
          general creditors of Company with respect to benefits due under
          the Plans or otherwise.

     (4)  Trustee shall resume the payments of benefits to Plan
          participants or their beneficiaries in accordance with Section 4
          of this Trust Agreement only after Trustee has determined that
          Company is not Insolvent (or is no longer Insolvent).

 
13

(c)  Provided that there are sufficient assets, if Trustee discontinues the
     payment of benefits from the Trust pursuant to Section 5(b) hereof and
     subsequently resumes such payments, the first payment following such
     discontinuance shall include the aggregate amount of all payments due to
     Plan participants or their beneficiaries under the terms of the Plans for
     the period of such discontinuance, less the aggregate amount of any
     payments made to Plan participants or their beneficiaries by Company in
     lieu of the payments provided for hereunder during any such period of
     discontinuance.

Section 6.  Payments to Company

(a)  In the event the Company delivers the Required Funding Amount to the
     Trustee because of a Potential Change in Control, the Trust Corpus shall be
     returned to the Company one year after delivery of the Required Funding
     Amount to the Trustee unless a Change in Control shall have occurred during
     such one-year period. Such one-year period shall recommence in the event of
     and upon the date of any subsequent Potential Change in Control. If another
     Potential Change in Control should occur after the Trust Corpus has been
     returned to the Company as provided in this Section 6(a), the Company shall
     deliver a new Required Funding Amount to the Trustee pursuant to Section 2.
     The Company shall notify the Trustee of the occurrence of a Potential
     Change in Control and Change in Control and the Trustee may rely on such
     notice.

(b)  Except as provided in Section 5 hereof, after the trust has become
     irrevocable, Company shall have no right or power to direct Trustee to
     return to Company or to divert to others any of the Trust assets before all
     payment of benefits have been made to Plan participants and their
     beneficiaries pursuant to the terms of the Plans.

Section 7.  Disposition of Income.

During the term of this trust, all income received by the Trust, net of
expenses and taxes, shall be accumulated and reinvested.

Section 8.  Claims Procedures

(a)  The Company agrees that by establishment of this Trust it hereby forgoes
     any review (judicial or otherwise) of certifications by the Recordkeeper as
     to the benefit payable to any persons hereunder.

 
14

(b)  If a dispute arises as to the amounts or timing of any benefits or the
     persons entitled thereto under this Trust, such dispute shall be resolved
     under a claims review procedure established and maintained by the
     Recordkeeper that includes the following:

     (1)  The manner in which a claim is made.

     (2)  Provisions to the effect that, in the event of a denial of a claim as
          to the amount of any distribution and/or the method of payment under
          any Plan by the Recordkeeper, a claimant will be given notice in
          writing of such detail within 90 days, which notice will set forth the
          reason for the denial, the pertinent Plan provision on which the
          denial is based, a description of the information necessary to perfect
          the claim and an explanation of why such information is necessary, and
          appropriate steps to be taken by the claimant to submit the claim for
          review.

     (3)  Provisions to the effect that the claimant may request a review of
          such denial by filing notice in writing with the Recordkeeper, within
          60 days after receipt of such denial, may review pertinent documents
          and may submit issues and comments in writing.

     (4)  Provisions for the Recordkeeper, in its discretion, to request a
          meeting to clarify an immediate matters it deems appropriate.

     (5)  Provisions to the effect that all interpretations, determinations, and
          decisions of the Recordkeeper in respect to any matter will be final,
          conclusive, and binding upon the claimant.

(c)  By making a Plan subject to the Trust, the claims review procedures of
     paragraph (b) of this Section 8 supersede any claims review procedures in
     the Plan to the extent of any benefits payable from the Trust.

Section 9.  Trustee

(a)  The duties and responsibilities of the Trustee shall be limited to those
     expressly set forth in this Trust, and no implied covenants or obligations
     shall be read into this trust against the Trustee.

 
15

(b)  The Trustee shall maintain such books, records and accounts as may be
     necessary for the proper administration of the Trust Corpus and shall
     render to the Company (and the Executives after a Change in Control of the
     Company has occurred), on or prior to each April 1 following the date this
     Trust was created until the termination of this Trust (and on the date of
     such termination), an accounting with respect to the Trust Corpus as of the
     end of the then most recent calendar year (and as of the date of such
     termination). Unless the Company (or any Executive after a Change in
     Control of the Company has occurred) shall have filed with the Trustee
     written exceptions or objections to any such statement and account within
     180 days after receipt thereof, the Company or any Executive, as the case
     may be, shall be deemed to have approved such statement and account, and in
     such case the Trustee shall be forever released and discharged with respect
     to all matters and things reported in such statement and account as though
     it had been settled by a decree of a court of competent jurisdiction in an
     action or proceeding to which the Company and any Executive were parties.

(c)  The Trustee shall not be liable for any act taken or omitted to be taken
     hereunder if taken or omitted to be taken by it in good faith. The Trustee
     shall also be fully protected in relying upon any notice given hereunder
     which it in good faith believes to be genuine and executed and delivered in
     accordance with this Trust.

(d)  The Trustee may consult with legal counsel to be selected by it, and the
     Trustee shall not be liable for any action taken or suffered by it in good
     faith in accordance with the advice of such counsel.

(e)  The Trustee shall be reimbursed by the Company for its reasonable expenses,
     including without limitation any expenses incurred under paragraph (g) of
     this Section 9, incurred in connection with the performance of its duties
     hereunder and shall be paid such fees for the performance of such duties as
     may be agreed upon in writing from time to time between the Company and the
     Trustee. After a Change in Control of the Company has occurred, the fees of
     the Trustee shall be determined by the application of the current rates
     then charged by the Trustee for the provision of the types of investment
     and trustee services contemplated in this Trust to trusts of a similar
     character. The Trustee's reasonable expenses and fees shall be paid in the
     manner provided by paragraph (f) of this Section 9.

 
16

(f)  The Company agrees to indemnify and hold harmless the Trustee from and
     against any and all damages, losses, claims or expenses as incurred
     (including expenses of investigation and fees and disbursements of counsel
     to the Trustee and any taxes imposed on the Trust Corpus or income of the
     Trust) arising out of or in connection with the performance by the Trustee
     of its duties hereunder. Any amount payable to the Trustee under paragraph
     (e) of this Section 9 or this paragraph (f) and not previously paid by the
     Company shall be paid by the Company promptly upon demand therefore by the
     trustee or, if the Trustee so chooses in its sole discretion, from the
     Trust Corpus. In the event that payment is made hereunder to the Trustee
     from the Trust Corpus, the Trustee shall promptly notify the Company in
     writing of the amount of such payment. The Company agrees that, upon
     receipt of such notice, it will deliver to the Trustee to be held in the
     Trust an amount in cash equal to any payments made from the Trust Corpus to
     the Trustee pursuant to paragraph (e) of this Section 9 or this paragraph
     (f), together with interest from the date of receipt of such notice based
     upon the daily average of the prime rate charged by the Trustee. The
     failure of the Company to transfer any such amount shall not in any way
     impair the Trustee's right to indemnification, reimbursement and payment
     pursuant to paragraph (e) of this Section 5.01 or this paragraph (f).

(g)  The Trustee is specifically authorized and required to take such action as
     may be necessary or appropriate, including the institution of litigation or
     other legal process, to enforce the Company's obligations hereunder or
     under the Plans on behalf of either itself or the Executives, and any
     expenses thus incurred by the Trustee shall be paid or reimbursed by the
     Company pursuant to paragraphs (e) and (f) of this Section 9.

(h)  Trustee shall have, without exclusion, all powers conferred on Trustees by
     applicable law, unless expressly provided otherwise herein, provided,
     however, that if an insurance policy is held as an asset of the Trust,
     Trustee shall have no power to name a beneficiary of the policy other than
     the Trust, to assign the policy (as distinct from conversion of the policy
     to a different form) other than to a successor Trustee, or to loan to any
     person the proceeds of any borrowing against such policy.

 
17

(i)  Notwithstanding any powers granted to Trustee pursuant to this Trust
     Agreement or to applicable law, Trustee shall not have any power that could
     give this Trust the objective of carrying on a business and dividing the
     gains therefrom, within the meaning of Section 301.7701-2 of the Procedure
     and Administrative Regulations promulgated pursuant to the Internal Revenue
     Code.

Section 10.  Resignation and Removal of Trustee.

(a)  The Trustee may resign at any time by written notice to the Company, which
     shall be effective 30 days after receipt of such notice unless Company and
     Trustee agree otherwise. If a Change of Control shall previously have
     occurred, the Trustee shall give such resignation notice, in writing, to
     the Company and the Executives, specifying a date (not less than 30 days
     after the giving of such notice) when such resignation shall take effect.
     Promptly after such notice, the Company, or if a Change in Control shall
     previously have occurred, the Company and at least 80% of the Executives
     then entitled to receive payments hereunder, shall appoint a successor
     trustee, such trustee to become Trustee hereunder upon the resignation date
     specified in such notice. If the Company and such Executives are unable to
     appoint a successor trustee within 60 days after such notice, the Trustee
     shall be entitled, at the expense of the Company, to petition a United
     States District Court or any court of competent jurisdiction in the state
     in which the Trustee maintains its principal place of business to appoint
     its successor, in accordance with section 10(c). The Trustee shall continue
     to serve until its successor accepts the Trust and receives delivery of the
     Trust Corpus. The Company, or if a Change in Control shall previously have
     occurred, the Company and at least 80% of the Executives then entitled to
     receive payments hereunder, may at any time substitute a new trustee by
     giving 15 days notice thereof to the Trustee then acting. In the event of
     such removal or resignation, the Trustee shall duly file with the Company
     and, on and after a Change in Control, the Executives, a written statement
     or statements of accounts and proceedings as provided in Section 9(b)
     hereof for the period since the last previous annual accounting of the
     Trust, and if written objections to such account are not filed as provided
     in Section 9(b) hereof, the Trustee shall to the maximum extent permitted
     by applicable law be forever released and discharged from all liability and
     accountability with respect to the propriety of its acts and transactions
     shown in such account. The Trustee and any successor thereto appointed
     hereunder shall be a corporate professional trustee which is not an
     affiliate of the Company but which has equity in excess of $100,000,000.00.

 
18

(b)  Upon resignation or removal of Trustee and appointment of a successor
     Trustee, all assets shall subsequently be transferred to the successor
     Trustee. The transfer shall be completed within 30 days after receipt of
     notice of resignation, removal or transfer, unless Company extends the time
     limit.

(c)  If Trustee resigns or is removed, a successor shall be appointed, in
     accordance with Section 10 hereof, by the effective date of resignation or
     removal under paragraph (a) of this section. If no such appointment has
     been made, Trustee may apply to a court of competent jurisdiction for
     appointment of a successor or for instructions. All expenses of Trustee in
     connection with the proceeding shall be allowed as administrative expenses
     of the Trust.

Section 11.  Termination

Except as provided herein, this Trust shall be irrevocable. At any time prior to
a Change in Control of the Company, this Trust may be terminated by the
Compensation Committee. Upon or after a Change in Control of the Company, this
trust shall not terminate until the date on which Plan participants and their
beneficiaries are no longer entitled to benefits pursuant to the terms of the
Plans unless sooner revoked in accordance with Section 2(b) hereof. Upon
termination of the Trust any assets remaining in the Trust shall be returned to
Company.

Section 12.  Amendment or Waiver

(a)  This Trust may be amended by a written instrument executed by Trustee and
     Company. Notwithstanding the foregoing, no such amendment shall conflict
     with the terms of the Plans or shall make the Trust revocable after it has
     become irrevocable in accordance with Section 2(b) hereof.

(b)  Upon and after a Change in Control of the Company, the following rules will
     govern amendments and waivers: (1) this Trust may not be amended except by
     an instrument in writing signed on behalf of the parties hereto together
     with the written consent of at least 80% of the Executives then entitled to
     receive payments hereunder; (2) the parties hereto, together with the
     consent of not less than 80% of the Executives then entitled to receive
     payments hereunder, may at any time waive compliance with any of the
     agreements or conditions contained herein; (3) any agreement on the part of
     a party hereto or an Executive to any such waiver shall be valid if set
     forth in an instrument in writing signed on behalf of such party or
     Executive; and (4) no such

 
19

     amendment or waiver relating to this Trust may be made with respect to a
     particular Executive unless such Executive has agreed in writing to such
     amendment or waiver.

Section 13.  Miscellaneous.

     ineffective to the extent of any such without invalidating the remaining
     provisions hereof.

(b)  Benefits payable to plan participants and their beneficiaries under this
     Trust Agreement may not be anticipated, assigned (either at law or in

          this Plan, if (A) Continuing Directors cease, within one year of a

     the Company; (2) and Person becomes the beneficial owner, directly or

     time be amended; (3) the submission of a nominee or nominees for the
     position of director of the Company by a shareholder or shareholders in a
