                              RABBI TRUST AGREEMENT


          CONOCO INC., formerly Conoco Energy Company (the "Company"), and U.S.
TRUST COMPANY, NATIONAL ASSOCIATION (the "Trustee") have as of December 17, 1999
(the "Effective Date"), entered into this grantor trust agreement ("Trust
Agreement"), established under the Company's nonqualified deferred compensation
plans included in the list set forth in Exhibit A attached hereto (the "Plan" or
"Plans"), as herein set forth.

          WHEREAS, the Company and/or one or more of the Company's affiliates
have adopted certain nonqualified deferred compensation Plans; and

          WHEREAS, the Company and/or one or more of the Company's affiliates
have incurred or expect to incur liability under the terms of such Plans with
respect to the individuals participating in such Plans ("Participants"); and

          WHEREAS, the Company wishes to establish a trust (the "Trust") and to
contribute to the Trust assets that shall be held therein, subject to the claims
of the Company's creditors in the event of the Company's Insolvency, as herein
defined, until paid to the Participants and their beneficiaries in such manner
and at such times as specified in the Plans; and

          WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of each Plan
as an unfunded plan maintained for the purpose of providing 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,
as amended ("ERISA"), an unfunded excess benefit plan, or a plan not subject to
ERISA; and

          WHEREAS, it is the intention of the Company to make contributions to
the Trust to provide a source of funds to assist it in the meeting of
Liabilities under the Plans;

          NOW, THEREFORE, the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:

     1.   ESTABLISHMENT OF TRUST:

          (a) The Company hereby deposits with Trustee in trust $2 million,
     which shall become the principal of the Trust to be held, administered and
     disposed of by the Trustee as provided in this Trust Agreement.

          (b) The Trust hereby established is revocable by the Company. It shall
     become irrevocable automatically upon the occurrence of a Change of
     Control. Upon the occurrence of a Change of Control or a Potential Change
     of Control, the Company shall promptly give written notice thereof to the
     Trustee.


                                       1
<PAGE>   2


          (c) The Trust is intended to be a grantor trust, of which the 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 (the
     "Code"), and shall be construed accordingly.

          (d) The principal of the Trust, and any earnings thereon (the "Trust
     Fund"), shall be held separate and apart from the Company's other funds and
     shall be used exclusively for the uses and purposes of Participants and the
     Company's general creditors as herein set forth. 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 Plan and
     this Trust Agreement shall be mere unsecured contractual rights of
     Participants and their beneficiaries against the Company. Any assets held
     by the Trust will be subject to the claims of the Company's general
     creditors under federal and state law in the event the Company is
     Insolvent, as defined in Section 3(a) herein.

          (e) Prior to a Change of Control, the Company, in its sole discretion,
     may at any time, or from time to time, make additional deposits of cash or
     other property in trust with the Trustee to augment the principal to be
     held, administered and disposed of by the Trustee as provided in this Trust
     Agreement. Prior to a Change of Control, neither the Trustee nor any
     Participant or beneficiary shall have any right or duty to compel such
     additional deposits or determine the sufficiency thereof.

          (f) Within 30 days following the end of each calendar year, the
     Company shall provide the Trustee with a written statement of all
     Liabilities as of the close of such calendar year, together with supporting
     calculations. Upon a Change of Control, the Company shall, as soon as
     practicable, but in no event later than the effective date of the Change of
     Control, (i) make an irrevocable contribution to the Trust in an amount
     equal to at least 100% of the Liabilities as determined by the Company in
     good faith in accordance with the methodology specified in Exhibit B as of
     the date on which the Change of Control occurred, plus the projected
     administrative expenses of the Trust for the one-year period following such
     funding, and (ii) provide the Trustee a written statement of such
     Liabilities and projected expenses, together with supporting calculations.

          (g) Within 30 days following the end of each calendar year ending
     after the Trust has become irrevocable pursuant to Section 1(b) hereof, the
     Company shall (i) irrevocably deposit cash, or other property acceptable to
     the Trustee, with the Trustee in an amount, when added to the assets then
     held by the Trustee, adequate to satisfy all Liabilities as of the close of
     such calendar year, as determined by the Company in good faith in
     accordance with the methodology specified in Exhibit B plus the projected
     administrative expenses of the Trust for the following calendar year, and
     (ii) provide the Trustee a written statement of such Liabilities and
     projected expenses, together with supporting calculations.


                                       2

          (h) The Company shall at all times ensure that the Plans and this
     Trust each shall have characteristics supporting a determination that they
     are not subject to ERISA, or are arrangements constituting unfunded plans
     maintained for the purpose of providing deferred compensation to a select
     group of management or highly compensated employees for purposes of Title I
     of ERISA.

     2.   PAYMENTS TO PARTICIPANTS AND THEIR BENEFICIARIES:

          (a) Annually, prior to a Change of Control, the Company shall deliver
     to the Trustee a schedule (the "Payment Schedule") that indicates the
     amounts payable in respect of each Participant (and his or her
     beneficiaries), that provides a formula or other instructions acceptable to
     Trustee for determining the amounts so payable, that indicates the form in
     which amounts are to be paid (as provided for or available under the
     appropriate Plan), and that indicates the time of commencement for payment
     of such amounts. Except as otherwise provided in Section 2(e) hereof or
     elsewhere herein, Trustee shall make payments to the Participants and their
     beneficiaries in accordance with such Payment Schedule. The Company shall
     provide in writing to the Trustee any and all information the Trustee
     reasonably believes necessary for the Trustee or its agent to make any
     determination as to payments to Participants, tax reporting, tax
     withholding or otherwise not less than 30 calendar days prior to the time
     the payments must be made. Within 20 days after a Change of Control, the
     Company shall deliver to the Trustee a then current Payment Schedule of
     benefits due under the Plans. Thereafter, the Trustee shall pay benefits
     due in accordance with such Payment Schedule. After a Change of Control,
     the Company shall continue to make the determination of benefits due to
     Participants or their beneficiaries and shall provide the Trustee with an
     updated Payment Schedule whenever appropriate; provided, however, that
     Participants or their beneficiaries may make application to the Trustee for
     an independent decision as to the amount or form of their benefits due
     under the Plans. In making any determination required or permitted to be
     made by the Trustee under this Section 2, the Trustee shall, in each such
     case, reach its own independent determination, in its absolute and sole
     discretion, as to the Participant's or beneficiary's entitlement to a
     payment hereunder. In making its determination, the Trustee may consult
     with and make such inquiries of such persons, including the Participant or
     beneficiary, the Company, legal counsel, actuaries or other persons, as the
     Trustee may reasonably deem necessary. Any reasonable costs incurred by the
     Trustee in arriving at its determination shall be reimbursed by the Company
     and, to the extent not paid by the Company within a reasonable time, shall
     be charged to the Trust. The Company waives any right to contest any amount
     paid over by the Trustee hereunder pursuant to a good faith determination
     made by the Trustee, notwithstanding any claim by or on behalf of the
     Company (absent a manifest abuse of discretion by the Trustee) that such
     payments should not be made or should not have been made.

          (b) The Trustee agrees that it will not itself institute any action at
     law or at equity, whether in the nature of an accounting, interpleading
     action, request


                                       3
<PAGE>   4


     for a declaratory judgment or otherwise, requesting a court or
     administrative or quasi-judicial body to make the determination required to
     be made by the Trustee under this Section 2 in the place and stead of the
     Trustee. The Trustee shall institute, and vigorously pursue, an action to
     collect a contribution due the Trust following a Change of Control or in
     the event that the Trust should ever experience a shortfall in the amount
     of assets necessary to make payments pursuant to the terms of the Payment
     Schedule following a Change of Control.

          (c) The Trustee shall make provision for the reporting and withholding
     of any federal taxes that may be required to be withheld with respect to
     the payment of benefits pursuant to the terms of a Plan and shall pay
     amounts withheld to the appropriate taxing authorities or determine that
     such amounts have been reported, withheld and paid by the Company. The
     Trustee shall make provision for the reporting and withholding of any state
     or local taxes that may be required with respect to the payment of benefits
     only as directed by the Company.

          (d) The Company shall, from time to time, pay taxes of any and all
     kinds whatsoever that at any time are lawfully levied or assessed upon or
     become payable in respect of the Trust Fund, the income or any property
     forming a part thereof or any security transaction pertaining thereto. To
     the extent that any taxes lawfully levied or assessed upon the Trust Fund
     are not paid by the Company, the Trustee shall have the power to pay such
     taxes out of the Trust Fund and shall seek reimbursement from the Company.
     Prior to making any payment, the Trustee may require such releases or other
     documents from any lawful taxing authority as it shall deem necessary. The
     Trustee shall contest the validity of taxes in any manner deemed
     appropriate by the Company or its counsel, but at the Company's expense,
     and only if it has received an indemnity bond or other security
     satisfactory to it to pay any such expenses. The Trustee shall not be
     liable for any nonpayment of tax when it distributes an interest hereunder
     on directions from the Company.

          (e) The Company may make payment of benefits directly to Participants
     or their beneficiaries as they become due under the terms of the relevant
     Plan. The Company shall notify the Trustee of its decision to make payment
     of benefits directly prior to the time amounts are payable to Participants
     or their beneficiaries and the Trustee's obligation to make payments under
     the Payment Schedule provided pursuant to Section 2(a) shall be modified
     accordingly. 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 Payment Schedule, the Company shall make the balance of
     each such payment as it falls due. The Trustee shall notify the Company in
     the event that principal and earnings are not sufficient (in addition to
     instituting and pursuing a collection action as described in Section 2(b),
     if applicable).

          (f) Notwithstanding anything contained in this Trust Agreement to the
     contrary, if at any time the Trust is finally determined by the Internal
     Revenue


                                       4
<PAGE>   5


     Service (the "IRS") not to be a "grantor trust" with the result that the
     income of the Trust Fund is not treated as income of the Company pursuant
     to Sections 671 through 679 of the Code, or if a tax is finally determined
     by the IRS to be payable by one or more Participants or beneficiaries with
     respect to any interest in the Plan or the Trust Fund prior to payment of
     such interest to such Participant or beneficiary, then the Trust shall
     automatically terminate 90 days following such final determination unless
     the Trustee has been provided written notice of the Company's,
     Participant's or beneficiary's intent to appeal such determination in which
     event the Trust shall automatically terminate 90 days following the
     determination of the IRS becoming final on appeal. Upon termination, the
     Trustee shall immediately distribute such interest in a lump sum to each
     Participant or beneficiary entitled thereto regardless of whether such
     Participant's employment has terminated and regardless of the form and time
     of payments specified in or pursuant to the relevant Plan as directed by
     the Company. Any remaining assets (less any expenses or costs due under
     Sections 9 and 13 of this Trust Agreement) shall then be paid by the
     Trustee to the Company in such amounts and in the manner instructed by the
     Company.

     3.   TRUSTEE RESPONSIBILITY REGARDING PAYMENTS WHEN THE COMPANY IS
INSOLVENT:

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

          (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 the Company under federal and state law
     as set forth below.

               (i) Each member of the Board of Directors acting in such capacity
          shall have the duty to inform the Trustee in writing of the Company's
          Insolvency; provided, however, such duty shall exist only if the
          Trustee has actual knowledge of the Company's Insolvency, or has
          received notice from a member of the Board of Directors or a person
          claiming to be a creditor alleging that the Company is Insolvent. If a
          person claiming to be a creditor of the Company notifies the Trustee
          that the Company has become Insolvent, the Trustee shall provide the
          Board of Directors with a copy of such writing, and absent the
          Company's provision of an independent expert's opinion satisfactory to
          the Trustee that the Company is not Insolvent, the Trustee shall
          discontinue payment of benefits to Participants or their
          beneficiaries.


                                       5
<PAGE>   6


               (ii) Unless the Trustee has actual knowledge of the Company's
          Insolvency, or has received notice from a member of the Board of
          Directors or a person claiming to be a creditor alleging that the
          Company is Insolvent, the Trustee shall have no duty to inquire
          whether the Company is Insolvent.

               (iii) If at any time the Trustee has received a written notice
          containing information or allegations described in Section 3(b)(i)
          that the Company is Insolvent, the Trustee shall discontinue payments
          to Participants and their beneficiaries and shall hold the assets of
          the Trust for the benefit of the Company's general creditors. Nothing
          in this Trust Agreement shall in any way diminish any rights of
          Participants or their beneficiaries to pursue their rights as general
          creditors of the Company with respect to benefits due under the Plan
          or otherwise.

               (iv) The Trustee shall resume the payment of benefits to
          Participants or their beneficiaries in accordance with Section 2 of
          this Trust Agreement only after it has been demonstrated to the
          Trustee's satisfaction that the Company is not Insolvent (or is no
          longer Insolvent).

          (c) Provided that there are sufficient assets, if the Trustee
     discontinues the payment of benefits from the Trust pursuant to Section
     3(b) hereof and subsequently resumes such payments, the first payment
     following such discontinuance shall include the aggregate amount of all
     payments due to Participants and their beneficiaries under the terms of the
     Plans for the period of such discontinuance plus, in each case, interest on
     any delayed payment at the annual percentage rate which is three percentage
     points above the interest rate shown as the Prime Rate in the Money Rates
     column in the then most recently published edition of The Wall Street
     Journal (Southwest Edition), or, if such rate is not then so published on
     at least a weekly basis, the interest rate announced by Chase Bank Texas,
     N.A. (or its successor), from time to time, as its "Base Rate" (or prime
     lending rate), from the date those amounts were required to have been paid
     until those amounts are finally and fully paid; provided, however, that in
     no event shall the amount of interest contracted for, charged or received
     hereunder exceed the maximum non-usurious amount of interest allowed by
     applicable law, less the aggregate amount of any payments made to
     Participants and their beneficiaries by the Company in lieu of the payments
     provided for hereunder during any such period of discontinuance.

     4.   PAYMENTS TO THE COMPANY:

          Except as provided in Sections 3, 8, 9 and 13 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


                                       6
<PAGE>   7


Trust assets before all payments of benefits have been made to Participants and
their beneficiaries pursuant to the terms of the Plans.

     5.   INVESTMENT AUTHORITY:

          The Trustee shall have, without exclusion, all powers conferred on the
Trustee by applicable law, unless expressly provided otherwise herein, and all
rights associated with assets of the Trust shall be exercised by the Trustee and
shall in no event be exercisable by or rest with Participants. The Trustee shall
have full power and authority to invest and reinvest the Trust Fund in any
investment permitted by law, subject to any investment guidelines provided in
Exhibit C hereto and any amendment to such Exhibit, exercising the judgment and
care that persons of prudence, discretion and intelligence would exercise under
the circumstances then prevailing considering the probable income and safety of

     or any state;

          (c) To hold, manage, improve and control all property, real or
     personal, forming part of the Trust Fund and to sell, convey, transfer,
     exchange, partition, lease for any term, even extending beyond the duration
     of this Trust, and otherwise dispose of the same from time to time in such
     manner for such consideration and upon such terms and conditions as the
     Trustee shall determine;

          (d) To have, respecting securities, all the rights, powers and
     privileges of an owner, including the power to give proxies, pay
     assessments and other sums deemed by the Trustee to be necessary for the
     protection of the Trust Fund, to vote any corporate stock either in person
     or by proxy, with or without power of substitution for any purpose; to
     participate in voting trusts, pooling agreements, foreclosures,
     reorganizations, consolidations, mergers and liquidations and, in
     connection therewith, to deposit securities with and transfer title to any
     protective or other committee under such terms as the Trustee may deem
     advisable; to exercise or sell stock subscriptions or conversion rights;
     and regardless of any limitation elsewhere in this document relative to
     investment by the Trustee, to accept and retain as an investment any
     securities or other property received through the exercise of any of the
     foregoing powers;


                                       7
<PAGE>   8


          (e) To hold in cash, without liability for interest, such portion of
     the Trust Fund which, in its discretion, shall be reasonable under the
     circumstances, pending investments or payments of expenses or the
     distribution of benefits;

          (f) To take such actions as may be necessary or desirable to protect
     the Trust Fund from loss due to the default on mortgages held in the Trust,
     including the appointment of agents or trustees in such other jurisdictions
     as the Trustee may deem desirable, to transfer property to such agents or
     trustees, to grant such powers as are necessary or desirable to protect the
     Trust or its assets, to direct such agents or trustees, or to delegate such
     power to direct and to remove such agents or trustees;

          (g) To employ such agents, including investment advisors, custodians,

          (h) To cause title to property of the Trust to be issued, held or
     registered in the individual name of the Trustee or in the name of its

          (i) To exercise all of the further rights, powers, options and
     privileges granted, provided for or vested in trustees generally under the
     laws of the State of California, so that powers conferred upon the Trustee
     herein shall not be in limitation of any authority conferred by law, but
     shall be in addition thereto;

          (j) To borrow money from any source (including the Trustee) and to
     execute promissory notes, mortgages or other obligations and to pledge or

          (m) To use securities, depositories or custodians and to allow such
     securities as may be held by a depository or custodian to be registered in
     the name of such depository or its nominee or in the name of such custodian
     or its nominee;

          (n) To invest the Trust Fund from time to time in one or more
     investment funds registered under the Investment Company Act of 1940
     (including companies with respect to which the Trustee or an affiliate is
     the investment adviser or provides other services);


                                       8
<PAGE>   9


          (o) To delegate its investment responsibility, in its sole discretion,
     to an investment manager who may be an affiliate of the Trustee. In the
     event the Trustee shall exercise this right, the Trustee shall remain, at
     all times, responsible for the acts of an investment manager;

          (p) To purchase an insurance policy or an annuity to fund the benefits
     of the Plans; and

          (q) To do all other acts necessary or desirable for the proper
     administration of the Trust Fund, as if the Trustee were the absolute owner
     thereof. However, nothing in this Section 5 shall be construed to mean the
     Trustee assumes any responsibility for the performance of any investment
     made by the Trustee in its capacity as trustee under this Trust Agreement.
     Notwithstanding any powers granted to the Trustee pursuant to this Trust
     Agreement or applicable law, the 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 Code.

In no event may the Trustee invest in securities (including stock or rights to
acquire stock) or obligations issued by the Company, other than a de minimis
amount held in common investment vehicles in which the Trustee invests.

     6.   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.

     7.   ACCOUNTING BY THE TRUSTEE:

          The Trustee shall keep accurate and detailed records of all
investments, receipts, disbursements and all other transactions required to be
made, including such specific records as shall be agreed upon in writing between
the Company and the Trustee. Within 120 days following the close of each
calendar year and within 120 days after the removal or resignation of the
Trustee, the Trustee shall deliver to the Company a written account of its
administration of the Trust during such year or during the period from the close
of the last preceding year to the date of such removal or resignation, setting
forth all investments, receipts, disbursements and other transactions effected
by it, 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 and
other property held in the Trust at the end of such year or as of the date of
such removal or resignation, as the case may be.

     8.   RESPONSIBILITY OF THE TRUSTEE:

          (a) The Trustee shall act with the care, skill, prudence and diligence
     under the circumstances then prevailing that a prudent person acting in
     like


                                       9

     capacity and familiar with such matters would use in the conduct of an
     enterprise of a like character and with like aims; provided, however, that
     the Trustee shall incur no liability to any person for any action taken
     pursuant to a direction, request or approval given in writing by the Board
     of Directors which is contemplated by, and in conformity with, the terms of
     the relevant Plan or this Trust Agreement. In the event of a dispute
     between the Company and another party, the Trustee may apply to a court of
     competent jurisdiction to resolve the dispute.

          (b) If the Trustee undertakes or defends any administrative,
     adversarial or other litigation or proceeding arising in connection with
     this Trust, the Company agrees to indemnify the Trustee against the
     Trustee's costs, expenses and liabilities (including, without limitation,
     attorneys' fees and expenses) relating thereto and the Company shall be
     primarily liable for such payments. The Company will, upon notice, pay
     monthly, in arrears, to or on behalf of the Trustee, all reasonable
     attorneys' fees and expenses incurred by the Trustee. If the Company does
     not pay such costs, expenses and liabilities in a reasonably timely manner,
     the Trustee may obtain payment from the Trust without notice to any party.

          (c) Prior to a Change of Control, the Trustee may consult with legal
     counsel (who may also, but need not, be counsel for the Company) generally
     with respect to any of its duties or obligations hereunder at the Company's
     expense which, should it remain unpaid, may be paid from the Trust without
     notice to any party. Following a Change of Control, the Trustee shall
     select independent legal counsel and may consult with counsel or other
     persons with respect to its duties and with respect to the rights of
     Participants or their beneficiaries under the Plans. The Trustee shall
     incur no liability to any person for acting or refraining from acting in
     accordance with the advice of such counsel.

          (d) The Trustee may hire agents, accountants, actuaries, investment
     advisors, financial consultants or other professionals to assist it in
     performing any of its duties or obligations hereunder at the Company's
     expense which, should it remain unpaid, may be paid from the Trust without
     notice to any party. The Trustee shall incur no liability to any person for
     acting or refraining from acting in accordance with the advice of such
     agents, accountants, actuaries, investment advisors, financial consultants
     or other professionals.

          (e) The 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. The
     Trustee shall not be liable for the failure or inability of an insurance
     company to pay the proceeds of any policy when due.


                                       10

          (f) The Company shall indemnify and hold the Trustee harmless from and
     against all loss or liability (including expenses and reasonable attorneys'
     fees), to which it may be subject by reason of its execution of its duties
     under this Trust, or by reason of any acts taken in good faith in
     accordance with any directions, or acts omitted in good faith due to
     absence of directions, from the Company or a Participant unless, and only
     to the extent, such loss or liability is due to the Trustee's negligence or
     willful misconduct.

          (g) The Company has represented to the Trustee that each Plan (i) is
     not subject to ERISA or (ii) qualifies as either (A) an excess benefit plan
     within the meaning of Section 4(b) of ERISA or (B) a "top-hat" plan
     maintained primarily for the purpose of providing deferred compensation for
     a select group of management or highly compensated employees, which is
     exempt from the provisions of Part 4 of Title I of ERISA. The Trustee is
     entering into this Trust Agreement in reliance upon the Company's
     representation. Accordingly, in the event that any Plan fails to meet one
     of the foregoing criteria then, notwithstanding any other provision of this
     Trust Agreement to the contrary, the Company will indemnify and hold the
     Trustee harmless from all liabilities, damages, costs and expenses
     (including, without limitation, reasonable attorneys' fees and expenses)
     that the Trustee incurs as a result of a breach of fiduciary duty under
     ERISA arising from any action taken, or omitted to be taken, by the Trustee
     in good faith in accordance with this Trust Agreement. In such event, the
     Company will, upon notice, pay monthly, in arrears to or on behalf of the
     Trustee, all reasonable attorneys' fees and expenses incurred by the
     Trustee. In the event that the Trustee is determined to have incurred any
     liability as a result of the Trustee's negligence or willful misconduct,
     the Trustee will promptly reimburse the Company for all legal fees and
     expenses paid by the Company to or on behalf of the Trustee.

          (h) In the event that the Trustee is named as a defendant in a lawsuit
     or proceeding involving any Plan or the Trust Fund, the Trustee shall be
     entitled to receive payments on a current basis pursuant to the indemnity
     provisions provided for in this Section 8; provided however, that if the
     final judgment entered in the lawsuit or proceeding holds that Trustee is
     guilty of negligence or willful misconduct with respect to the Trust Fund,
     the Trustee shall be required to refund the indemnity payments that it has
     received.

          (i) All releases and indemnities provided in this Trust Agreement
     shall survive the termination of this Trust Agreement. The Company shall
     indemnify and hold harmless the Trustee for any actions of a prior trustee.

     9.   COMPENSATION AND EXPENSES OF TRUSTEE:

          (a) The Trustee shall be entitled to reasonable compensation for its
     services as agreed upon between the Trustee and the Company and as set
     forth from time to time in Exhibit D attached hereto and incorporated
     herein by this reference. If the Trustee and the Company fail to agree upon
     a compensation


                                       11
<PAGE>   12


     agreement, the Trustee shall be entitled to compensation at a rate equal to
     the rate charged by the Trustee for similar services rendered by it during
     the current fiscal year for other trusts similar to this Trust. The
     Trustee's compensation and expenses shall be paid by the Company. The
     Trustee is authorized to withdraw such amounts from the Trust Fund if the
     Company fails to pay such amounts within 60 days of presentation of a
     statement of the amounts due.

          (b) Upon the occurrence of an extraordinary event, such as a Change of
     Control, or any other matter which in the Trustee's discretion requires the
     Trustee to perform material services in addition to the Trustee's custodial
     and investment responsibilities under this Trust Agreement (an "Event"),
     the Trustee shall be entitled to an additional fee, as of the date of the
     Event, calculated as follows: (i) for administrative services related to
     the Event, a fee negotiated in good faith within 10 days of the Event, plus
     compensation at the Trustee's normal hourly rates for services not
     contemplated by the negotiated fee; and (ii) for investment management
     services, the applicable published fee schedule of the Trustee.

          (c) The Trustee is authorized to incur reasonable expenses in
     connection with the administration of the Trust, including, but not limited
     to, fees and expenses incurred pursuant to Section 8(c) and Section 8(d).
     Such expenses shall be paid by the Company. The Trustee is authorized to
     pay such amounts from the Trust Fund if the Company fails to pay them
     within 60 days of presentation of a statement of the amounts due.

     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 the Company and the Trustee agree otherwise; provided, however, that
     any such resignation shall be effective only after the appointment of a
     successor trustee.

          (b) The Trustee may be removed by the Company on 30 days' written
     notice or upon shorter written notice accepted by the Trustee prior to a
     Change of Control. Subsequent to a Change of Control, the Trustee may be
     removed by the Company only with the consent of a majority of the
     Participants.

          (c) If the Trustee resigns within two years after a Change of Control,
     the Company, or, if the Company fails to act within a reasonable period of
     time following such resignation, the Trustee shall apply to a court of
     competent jurisdiction for the appointment of a successor trustee or for
     instructions.

          (d) Upon resignation or removal of the Trustee and appointment of a
     successor trustee, all assets shall subsequently be transferred to the
     successor trustee. The transfer shall be completed within 60 days after
     receipt of notice of resignation, removal or transfer, unless the Company
     extends the time limit.


                                       12
<PAGE>   13


          (e) If the Trustee resigns or is removed, a successor shall be
     appointed, in accordance with Section 11 hereof, by the effective date of
     resignation or removal under paragraph (a) or (b) of this Section. If no
     such appointment has been made, the Trustee may apply to a court of
     competent jurisdiction for appointment of a successor or for instructions.
     All expenses of the Trustee in connection with the proceeding shall be
     allowed as administrative expenses of the Trust.

     11.  APPOINTMENT OF SUCCESSOR:

          (a) If the Trustee resigns or is removed in accordance with Section 10
     hereof, the Company or the Trustee, as applicable, may appoint or apply to
     a court for appointment, subject to Section 10, of any independent third
     party national banking association with a market capitalization exceeding
     $100,000,000 to replace the Trustee upon resignation or removal. The
     appointment shall be effective when accepted in writing by the new trustee,
     who shall have the rights and powers of the former trustee, including
     ownership rights in the Trust assets, upon transfer of same to the new
     trustee. The former trustee shall execute any instrument necessary or
     reasonably requested by the Company or the successor trustee to evidence
     the transfer.

          (b) The successor trustee need not examine the records and acts of any
     prior trustee and may retain or dispose of existing Trust assets, subject
     to Sections 7 and 8 hereof. The successor trustee shall not be responsible
     for, and the Company shall indemnify and defend the successor trustee from,
     any claim or liability resulting from any action or inaction of any prior
     trustee or from any other past event, or any condition existing at the time
     it becomes successor trustee.

     12.  AMENDMENT OR TERMINATION:

          (a) This Trust Agreement may be amended by a written instrument
     executed by the Trustee and the Company. Notwithstanding the foregoing, no
     such amendment shall (i) conflict with the terms of any Plan, (ii) make the
     Trust revocable after it has become irrevocable in accordance with Section
     1(b) hereof, (iii) cause the Trust not to qualify as a grantor trust, or
     (iv) be made to Section 13 during any Legal Defense Fund Period or to any
     provision of this Trust Agreement after the Trust has become irrevocable in
     accordance with Section 1(b) hereof, if, in either case, such amendment
     would, in the judgment of the Trustee, be adverse to the interests of any
     Participant.

          (b) The Trust shall not terminate until the date on which Participants
     and their beneficiaries are no longer entitled to benefits pursuant to the
     terms of any Plan and all liabilities have been satisfied. Upon termination
     of the Trust, any assets remaining in the Trust shall be returned to the
     Company. Such remaining assets shall be paid by the Trustee to the Company
     in such amounts and in the manner instructed by the Company, whereupon the
     Trustee shall be


                                       13
<PAGE>   14


     released and discharged from all obligations hereunder. From and after the
     date of termination, and until final distribution of the Trust Fund, the
     Trustee shall continue to have all of the powers provided herein as are
     necessary or expedient for the orderly liquidation and distribution of the
     Trust Fund.

     13.  LEGAL DEFENSE FUND:

          (a) The Trustee shall establish within the Trust Fund a separate fund,
     hereinafter referred to as a "Legal Defense Fund." The Legal Defense Fund
     shall consist of such portions of the contributions to the Trust as the
     Company shall specify in writing at the time of contribution, together with
     all income, gains and losses and proceeds from the investment, reinvestment
     and sale thereof, less all payments therefrom and expenses charged thereto
     in accordance with the provisions of this Section 13. Subject to Section 3,
     the Legal Defense Fund shall be held and administered by the Trustee for
     the purpose of defraying the costs and expenses incurred by Participants
     and beneficiaries associated with the enforcement of their rights under any
     Plan by litigation or other legal action and the Trustee in performing its
     duties under this Section. Upon the initial contribution ("Legal Defense
     Fund Date") by the Company designated as constituting a part of the Legal
     Defense Fund, the portion of this Trust so designated, together with
     earnings allocable thereto, shall be held exclusively for use of the Legal
     Defense Fund for a period of not less than five years from the Legal
     Defense Fund Date ("Legal Defense Fund Period"). At each anniversary of the
     Legal Defense Fund Date, the Legal Defense Fund Period shall be extended
     for an additional year unless the Board has determined in good faith and
     the Trustee concurs in writing, that (i) no Change of Control has occurred
     or if such an event has occurred all Liabilities have been satisfied, (ii)
     at that time there is no Potential Change in Control Period, and (iii) if
     the Trust has become irrevocable pursuant to Section 1(b), all Liabilities
     have been satisfied.

          (b) The Legal Defense Fund shall be maintained and administered as a
     separate segregated amount; provided, however, that the assets of the Legal
     Defense Fund may be commingled with all other assets of the Trust, and with
     the assets of any other trust, solely for investment purposes.

          (c) If, at any time after a Change of Control or during a Potential
     Change of Control Period, legal proceedings are brought against the Trustee
     by the Company or another party seeking to invalidate any of the provisions
     of this Trust Agreement as they relate to the Trust, or seeking to enjoin
     the Trustee from paying any amounts from any trust or from taking any other
     action otherwise required or permitted to be taken by the Trustee under
     this Trust Agreement with respect to any trust, the Trustee shall take all
     steps that may be necessary in such proceeding to uphold the validity and
     enforceability of the provisions of this Trust Agreement as they relate to
     such trust. The Trustee shall be empowered to retain counsel and other
     appropriate experts, including actuaries and accountants, to assist it in
     making any determination under this Section 13. All costs and expenses
     incurred by the Trustee in connection with any such proceeding


                                       14
<PAGE>   15


     (including, without limitation, the payment of reasonable fees, costs and
     disbursements of any counsel, actuaries, accountants or other experts
     retained by the Trustee in connection with such proceeding) shall be
     charged to and paid from the Legal Defense Fund. To the extent the
     Trustee's legal fees and expenses exceed the amount available in the Legal
     Defense Fund, such fees and expenses shall be paid by the Trustee from the
     assets of the Trust Fund.

          (d) If, at any time after a Change of Control, a Participant or
     beneficiary notifies the Trustee in writing that the Company has refused to
     pay a claim asserted by such Participant or beneficiary under any Plan, the
     Participant or beneficiary ("Claimant") may demand payment from the Legal
     Defense Fund with respect to expenses incurred in connection with the
     initiation or defense of any litigation or other legal action by or against
     the Company or any director, officer, stockholder or other person
     affiliated with the Company with respect to such claim. Such demand shall
     be made in writing, by delivering to the Trustee, within 90 days of the
     date the Claimant incurs such expenses, (i) a certification signed by the
     Claimant that the Company is in default in paying its obligations under the
     Plan and (ii) itemizing in reasonable detail in a form acceptable to the
     Trustee the expenses payable by the Legal Defense Fund.

          (e) In the event that, on the date a Claimant's expenses are to be
     paid from the Legal Defense Fund, other expenses have been claimed but not
     yet paid and the aggregate amount of all claims exceeds the amount
     available in the Legal Defense Fund, the Company shall be obligated to make
     an additional contribution to the Legal Defense Fund. In the event the
     Company fails to make such additional contribution, the Trustee shall
     promptly advise the Claimant and shall only pay that portion of the amount
     of the claim to each Claimant determined by multiplying such Claimant's
     expenses by a fraction, the numerator of which is the amount held in the
     Legal Defense Fund and the denominator of which is the aggregate expenses
     claimed by all Claimants.

          (f) Notwithstanding any provision herein to the contrary, the Trustee
     shall be required to act under this Section only to the extent there are
     sufficient amounts available in the Legal Defense Fund to defray the costs
     and expenses the Trustee reasonably anticipates will be incurred in
     connection with such action.

          (g) The Company's Legal Defense Fund shall continue to be held and
     administered by the Trustee for the purposes described in this Section 13
     until such time as all liabilities for benefits to which all Participants
     are entitled under all Plans shall have been paid in full to such
     Participants or their beneficiaries. Any balance then remaining in the
     Legal Defense Fund shall be distributed to the Company.

     14.  MISCELLANEOUS:

          (a) Any provision of this Trust Agreement prohibited by law shall be
     ineffective to the extent of any such prohibition, without invalidating the
     remaining provisions hereof.

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

     respective successors and assigns of the Company and the Trustee. Any
     corporation that succeeds to substantially all of the business of the
     Trustee by merger, consolidation, purchase or otherwise shall, upon
     succession and without appointment or other action by the Company, be and
     become successor Trustee hereunder. The Board may delegate any or all of
     its responsibilities or authority hereunder, or that of any of its members
     hereunder, to any officer of the Company by providing written notice to the
     Trustee of such delegation.

          (e) Any communication to the Trustee, including any notice, direction,
     designation, certification, order, instruction or objection, shall be in

     Agreement that governs same. The Trustee shall be fully protected and
     indemnified by the Company in acting in accordance with such written
     communications. Any notice required or permitted to be given hereunder
     shall be deemed given if written and hand delivered, mailed, postage
     prepaid, certified mail, return receipt requested or transmitted by

          (a) such Person or any of such Person's Affiliates and Associates,
     directly or indirectly, is the "beneficial owner" of (as determined

     Exchange Act, as in effect on the date of this Trust Agreement) such
     securities or otherwise has the right to vote or dispose of such

     understanding (whether or not in writing); provided, however, that a Person
     shall not be deemed the "Beneficial Owner" of, or to "beneficially own,"
     any security under this subsection (a) as a result of an agreement,
     arrangement or understanding to vote such security if such agreement,

     consent given in response to a public (i.e., not including a solicitation
     exempted by Rule 14a-2(b)(2) of the General Rules and Regulations under the
     Exchange Act) proxy or consent solicitation made pursuant to, and in

<PAGE>   18


          (b) such Person or any of such Person's Affiliates and Associates,
