         WHEREAS, the Company (or certain of its subsidiaries) is or may become
     obligated under certain employee benefit plans, agreements, or other
     arrangements, to make payments to certain persons who at any time prior to
     the occurrence of a change in control of the Company were employees of the
     Company (or certain of its subsidiaries) (the "Plan Participants") and
     their beneficiaries; and

         WHEREAS, in order to: (1) provide an alternative source of funds to
     assist the Company in meeting its liabilities under the applicable employee

     applicable employee benefit plans, agreements, or other arrangements; and

         WHEREAS, it is the intention of the parties that this Trust 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, as amended
     ("ERISA"); and

         WHEREAS, Bankers Trust Company is willing to act as Trustee of the

                            Establishment of Trust

     3.1  Principal of Trust. The Company hereby deposits with the Trustee in
          ------------------
trust the sum of One Hundred Dollars ($100.00) in cash which shall become the
principal of the Trust to be held, administered and disposed of by the Trustee
as provided in this Trust Agreement.

     3.2  Term and Revocability. The Trust hereby established is revocable by
          ---------------------
the Company, but shall become irrevocable upon the occurrence of a Potential
Change in Control or a Change in Control. At any time following the occurrence
of a Potential Change in Control, this Trust may not be terminated either by the
Company or the Board of Directors (or any member or committee thereof). Upon or
after a Change in Control, 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. Upon termination of the Trust any
assets remaining in the Trust shall be returned to the Company.

          -----------------------------------------

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 shall be mere unsecured contractual rights of Plan
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 of Insolvency.

                            Administration of Trust

     4.1  Authority and Duties of the Committee. It shall be the duty of the
          -------------------------------------
Committee, on the basis of information supplied to it by the Company, to
determine

          (a)  the eligibility of each Plan Participant to receive payment of
     benefits under this Trust with respect to each Plan; and

          (b)  the manner and time of payment of the benefits payable hereunder.

                                       6
<PAGE>

     The Recordkeeper shall determine, on behalf of the Committee, the amount of
any benefit payable under this Trust to which each Plan Participant may be
entitled. The Trustee, on behalf of the Company, shall make such payments as the
Committee instructs the Trustee to pay, to Plan Participants. The Committee
shall have the full power and authority to manage claims and appeals as set
forth in the respective Plan, and to construe, interpret and administer such
Plan in accordance with its terms and provisions.

     Prior to any Change in Control, the non-employee members of the Committee
(if any) shall be compensated by the Company at a rate to be determined by the
Chief Executive Officer. Following a Change in Control, any member of the
Committee whose employment with the Company has terminated in connection with
the Change in Control shall be compensated for services performed under this
Trust at the rate in effect for any non-employee members immediately preceding a
Change in Control, or, if no such rate is in effect, in an amount not to exceed
25% of such individual's annual base salary as paid by the Company immediately
prior to his or her employment termination date. Following a Change in Control,
such compensation shall be paid from the Trust assets.

     4.2 Action by the Committee. A majority of the members of the Committee
         -----------------------
shall constitute a quorum for the transaction of business at a meeting of the
Committee. Any action of the Committee may be taken upon the affirmative vote of
a majority of the members of the Committee at a meeting, or without a meeting by
mail, telegraph, telephone or electronic communication device; provided,
however, that all of the members of the Committee are informed of their right to
vote on the matter before the Committee and of the outcome of the vote thereon.

     4.3 Records, Reporting and Disclosure. The Committee shall keep all
         ---------------------------------
individual and group records relating to Plan Participants and former Plan
Participants and all other records necessary for the proper administration and
operation of the Trust. Such records shall be made available to the Company and
to each Plan Participant for examination during business hours except that a
Plan Participant shall examine only such records as pertain exclusively to the
examining Plan Participant and to the Plan, in general. The Committee shall
prepare and shall file as required by law or regulation all reports, forms,
documents and other items required by the Internal Revenue Code, and every other
applicable statute, each as amended, and all regulations thereunder (except that
the Company, as payer of the benefits, shall prepare and distribute to the
proper recipients all forms relating to withholding of income or wage taxes,
Social Security taxes, and other amounts which may be similarly reportable).

     All income, deductions and credits attributable to the Trust belong to the
Company and will be included on the Company's income tax returns. The Company
shall pay any federal, state, local, or other taxes imposed or levied with
respect to the assets and/or income of the Trust or any part thereof under
existing or future laws. Upon furnishing the Trustee with evidence reasonably
re-

                                       7
<PAGE>

quired by the Trustee of any such tax payments made directly by the Company, the
Company shall be entitled to receive reimbursement from the assets of the Trust
for the full amount of such taxes paid by it.

     4.4 Bonding. The Committee shall arrange any bonding that may be required
         -------
by law, but no amount in excess of the amount required by law (if any) shall be
required by the Trust.

                                   ARTICLE V

                Potential Change in Control; Change in Control

     5.1 Potential Change in Control. If a Potential Change in Control occurs,
         ---------------------------
the Company shall immediately notify the Trustee and Recordkeeper and shall
cause the Required Funding Amount to be remitted to the Trustee as a
contribution to the Trust. The Required Funding Amount shall be paid to the
Trust not later than thirty (30) days after the Potential Change in Control.

     5.2 Change in Control. Whenever a Change in Control is expected to occur,
         -----------------
if the date it will occur (the "CIC Date") is reasonably ascertainable, then (i)
the Company shall notify the Trustee and the Recordkeeper of the CIC Date, (ii)
the Legal Defense Fund Amount and the Required Funding Amount shall be
determined as of the CIC Date, and (iii) to the extent that the amount then held
in the Legal Defense Fund or the balance of the Trust Corpus is less than the
Legal Defense Fund Amount or the Required Funding Amount, respectively, the
Company shall cause the amount of the shortfall to be remitted to the Trustee as
an irrevocable contribution to the Trust not later than one (1) business day
before the CIC Date. If a Change in Control occurs, the Company shall
immediately notify the Trustee and Recordkeeper. In addition, the Required
Funding Amount shall be determined as of the actual date of the Change in
Control and, to the extent that the amount then held in the Trust Corpus (other
than the Legal Defense Fund) is less than the Required Funding Amount, the
Company shall immediately cause the amount of the shortfall to be remitted to
the Trustee, as an irrevocable contribution to the Trust, not later than one (1)
business day after the Change in Control.

     5.3 Method of Funding. The contribution of the Required Funding Amount
         -----------------
shall be made in cash or in property acceptable to the Trustee having a fair
market value equal to the Required Funding Amount, or in a combination of the
two. The Board of Directors may determine that all or a portion of the Required
Funding Amount and the Legal Defense Fund Amount may be represented by a
standby, irrevocable (except as provided in Section 9.1) letter of credit, drawn
on a bank acceptable to the Trustee, against which the Trustee may draw
sufficient funds that, with the amounts contributed in cash or other property,
will enable the Trustee to make the payments due under the Plans, together with
the fees and expenses described in Section 5.1 above.

     5.4 Additional Contributions; Sufficiency of Funds. The Company shall be
         ----------------------------------------------
obligated to continue to cause additional contributions (or increases to the
amount that may be drawn against the letter of

                                       8
<PAGE>

credit) to be made as may be necessary from time to time to insure that at all
times following a Change in Control, the Trust contains sufficient funds, on a
current basis, to pay all benefits due to the Plan Participants (or their
designated beneficiaries) under the Plans, together with the fees and expenses
described in Section 5.1. The Trustee shall be under no duty to determine the
sufficiency, or to enforce the making, of such contributions by the Company.

     5.5 Additional Plans. In the event the Compensation Committee designates
         ----------------
additional Plans that are subject to this Trust Agreement, or the Plans subject
to this Trust Agreement are amended, after a Potential Change in Control or
Change in Control, the Treasurer of the Company shall, unless the Trust Corpus
shall theretofore have been released pursuant to Section 9.1 hereof, recalculate
the Required Funding Amount. If the amount so calculated exceeds the fair market
value of the assets then held in trust (excluding the Legal Defense Fund), the
Company shall promptly (and in no event later than thirty (30) days from the
date of such recalculation):

         (a) 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; or

         (b) increase the amount that may be drawn against the letter of credit
     described in Section 5.3, above, to cover 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.

     5.6 Calculation of Required Funding Amount. As soon as practicable, but in
         --------------------------------------
no event later than fifteen (15) days following the occurrence of any Potential
Change in Control, the Treasurer of the Company shall compute the Required
Funding Amount. Immediately thereafter, the Recordkeeper shall review the
Treasurer's calculations of the Required Funding Amount (including without
limitation the calculations under Section 5.5 hereof). The Recordkeeper shall
complete its review prior to the thirtieth (30th) day following any Potential
Change in Control. If the Recordkeeper concludes that the amounts calculated by
the Treasurer are not sufficient to permit the Trustee to make all payments due
or to become due under the Plans, together with the fees and expenses described
in Section 5.1 above, the Treasurer shall increase the Required Funding Amount
to the amount so calculated by the Recordkeeper. The Company agrees not to
challenge the calculations of the Treasurer, and both the Company and the
Treasurer agree not to challenge the calculations of the Recordkeeper, and the
Trustee shall have no right or obligation to challenge or question such
calculation with regard to the Required Funding Amount (including, without
limitation, the amount determined under Section 5.5 hereof) upon and after a
Potential Change in Control or Change in Control. No Plan Participant shall have
the right to challenge the calculations of either the Treasurer or the
Recordkeeper with respect to the Required Funding Amount.

                                       9
<PAGE>

     5.7 Payment of Required Funding Amount.
         ----------------------------------

         (a) Interest on Delinquent Payments. The Company agrees to pay interest
     on any delinquent payment of the Required Funding Amount from the date on
     which such payment is required to be made pursuant to this Article V, based
     upon the daily average of the prime rate charged by Trustee, or its United
     States banking affiliate, during the period of such deficiency.

         (b) Discount Rate for Distributions Due Later. In determining the
     Required Funding Amount with respect to any payment or series of payments
     expected to be due more than one (1) 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.

         (c) Schedule of Accounts. Each payment by the Company pursuant to this
     Article V shall be accompanied by a schedule delivered to the Recordkeeper
     (as described in Section 7.4 hereof) 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. On a monthly basis, the Trustee shall advise the
     Recordkeeper in writing regarding the actual amounts received by the Trust
     from the Company, and paid out from the Trust, in respect of each of the
     Plans.

     5.8 Legal Defense Fund. The Trustee shall establish a separate account (the
         ------------------
"Legal Defense Fund") to provide for the payment of legal expenses and
liabilities incurred by the Trustee with respect to which it is entitled to
reimbursement under Sections 10.3 and 10.4, or for which a Plan Participant is
entitled to reimbursement under Section 10.5, and to protect Plan Participants'
rights to benefits after a Change in Control. Upon a Potential Change in
Control, the Company shall contribute cash to the Legal Defense Fund in an
amount equal to the greater of ten percent (10%) of the Required Funding Amount
(or a reasonable estimate thereof) and $5,000,000 (the "Legal Defense Fund
Amount"). The Legal Defense Fund shall not be used to pay benefits due under any
Plan.

     5.9 Sunset Provision. Subject to Section 9.3, anything to the contrary in
         ----------------
this Trust Agreement or the Plans notwithstanding, in the event of a Potential
Change in Control, the procedures, rules and responsibilities that apply under
this Article V and under Sections 2.1, 3.2, 6.4, 7.3, 7.4, 10.2

                                       10
<PAGE>

and 14.3(b) hereof solely as a result of the occurrence of such Potential Change
in Control shall cease to apply six (6) months after delivery of the Required
Funding Amount to the Trustee if no Change in Control shall have occurred during
such six-month period, and the Board of Directors determines, and so certifies
to the Trustee, that a Change in Control is not imminent, pending, or reasonably
expected to occur (or upon such certification by non-employee members of the
Board of Directors acting unanimously before the expiration of such six-month
period), or upon the earlier termination of this Trust in a manner consistent
with Section 3.2 hereof. Such six-month period shall recommence in the event of
and upon the date of any subsequent Potential Change in Control.

                                  ARTICLE VI

                             Investment Authority

     6.1 Authority of Trustee. 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 One Hundred Million Dollars
($100,000,000.00). Discretionary authority for the management and control of the
assets of the Trust shall be retained by the Trustee, and all rights associated
with assets of the Trust shall be exercised by the Trustee or the person
designated by the Trustee, and shall in no event be exercisable by, or rest
with, the Plan Participants.

     The assets of the Trust shall be invested and re-invested, without
distinction between principal and income, at such time or times in such
investments, pursuant to such investment strategies or courses of action and in
such shares and proportions as the Trustee, in its sole discretion shall deem
advisable, subject to the applicable investment policies and related guidelines
established by the Committee. These investment policies and related guidelines
shall be communicated by the Committee to the Trustee. The Committee shall
monitor compliance with such investment policies and related guidelines.

     Subject to the applicable investment policies and related guidelines, and
subject to the requirements of Section 6.2 hereof after a Change in Control, the
Trustee shall have the following powers and discretions in addition to those
conferred by law:

     as the Trustee may deem best, and no person dealing with the Trustee shall

     the validity, expediency or propriety of any such sale or other
     disposition;

         (c)  Settlement of Debts. To compromise, compound and settle any debt
     or obligation (except claims by Plan Participants for benefits under any
     Plan) due to or from the Trust and to reduce the rate of interest thereon,

         meeting of stockholders or security holders, in respect to any business
         which may come before the meeting;

              (2) to exercise any options appurtenant to any stocks, bonds or
         other securities for the conversion thereof into other stocks, bonds or
         securities;

              (3) 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

              (4) to join in, and to approve, or to dissent from and to oppose,
         any corporate act or proceeding, including any reorganization,

         in the Trust Corpus;

              (5) to deposit with any committee or depository, pursuant to any

         and

              (6) to make payment from the Trust Corpus of any charges or
         assessments imposed by the terms of any such plan or agreement;

     such terms and conditions as 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;

         (h) Enforcement Authority. 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;

         (i) Execution of Instruments. 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;

         (j) Registration and Transfer of Investments. 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, to retain securities at a
     qualified central depository or Federal Reserve Bank 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;

         (k) Uninvested Assets. To hold any part or all of the Trust Corpus
     uninvested; and

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

     6.2 Investment Following Change in Control. 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 the Trustee believes prudent under the
circumstances (taking into account, among other things, the anticipated cash
requirements for the payment of benefits under the Plans communicated to the
Trustee by the Recordkeeper) solely in:

         (a) direct obligations of the United States of America or agencies
     thereof;

         (b) obligations unconditionally and fully guaranteed as to principal
     and interest by the United States of America; or

                                       13
<PAGE>

         (c) any registered investment fund, including a fund for which the
     Trustee serves as investment manager and/or custodian, established and
     maintained as a vehicle for short-term investment.

     With respect to such investments, the Trustee shall have the powers and
discretion set forth in Section 6.1 hereof, in addition to those conferred by
law; provided, however, that the Trustee shall not be liable for: (1) any losses
to the Trust resulting from compliance with the investment and diversification
limitations imposed by this Section 6.2, or (2) 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 Agreement.

     6.3 Investment of Trust Income. During the term of this Trust, income
         --------------------------
received by the Trust, net of expenses and taxes, shall be accumulated and
reinvested.

     6.4 Losses Charged Against Trust Corpus. All losses of income or principal
         -----------------------------------
in respect of, and expenses (including without limitation taxes and, as provided
in Article XI 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 following a Potential Change in Control
or a Change in Control for any loss in principal amount of, or expense charged
against, the Trust Corpus except to the extent that the fair market value of the
Trust Corpus as of that date equals or exceeds the Required Funding Amount as of
that date. 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.

                                   ARTICLE VII

              Payments to Plan Participants and Their Beneficiaries

     7.1 Appointment of Recordkeeper. It is recognized that the Trustee shall
         ---------------------------
have no responsibility hereunder for the continued retention of the Recordkeeper
and/or any responsibility assigned to the Recordkeeper or its performance
thereof. The Company shall pay the Trustee for all fees and expenses of the
Recordkeeper.

     7.2 Maintenance of Records. 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 Trust
Agreement, including the maintenance of records for the separate Accounts of
each Plan under this Trust Agreement and the maintenance of Plan Participants'
Plan interests. The Recordkeeper shall maintain individual records with respect
to each Plan Participant's interest under each Plan.

                                       14
<PAGE>

     7.3 Company Information. As soon as practicable, but in no event later than
         -------------------
fifteen (15) days following the occurrence of any Potential Change in Control,
the Recordkeeper shall identify to the Company in writing the information deemed
necessary to enable the Recordkeeper to determine the amount of benefits payable
to or with respect to each Plan Participant in each Plan, including any benefits
payable after the Plan Participant's death, and the recipient. As soon as
reasonably practicable after receiving such communication from the Recordkeeper
following any Potential Change in Control, the Company shall furnish the
information needed by the Recordkeeper in order to determine the amount of any
such benefit, and shall deliver to the Recordkeeper a letter of instructions:

         (a) describing the terms of each Plan;

         (b) enclosing a copy of each Plan;

         (c) listing the names, addresses, and Hay points or grade levels under
     the salary administration program then in effect, for the Plan Participants
     (and beneficiaries) covered by each Plan;

         (d) setting forth the timing, form of distributions, and formula or
     other methodology for determining the amounts to be paid to each Plan
     Participant and beneficiary under each Plan; and

         (e) instructing the Recordkeeper how and from whom to get any other
     information needed to compute benefits under each Plan.

     Thereafter, 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 Plan Participant information, as contemplated
herein, the Recordkeeper shall be entitled to rely upon the most recent
information furnished to it by the Company.

     7.4 Payment Schedule. Within forty-five (45) days following a Change in
         ----------------
Control or Potential Change in Control (or when the Company otherwise makes
contributions to the Trust), the Recordkeeper, on behalf of the Company, shall
deliver to the Trustee a schedule (the "Payment Schedule") that indicates:

         (a) in the case of all Plans, except the Special Employee Severance
     Plan, the amounts payable (including the fees and expenses incurred by the
     Plans) in respect of each Plan Participant (and his or her beneficiaries);
     and

         (b) in the case of the Special Employee Severance Plan, the amount
     reasonably expected to be payable thereunder, in order to fully fund the
     benefits due to those Participants then in grades 11 through 13, together
     with an explanation of the assumptions used by the Recordkeeper in
     performing its calculation.

         The Payment Schedule shall be updated by the Recordkeeper as necessary,
but on at least an annual basis, in order to reflect changes therein. Upon the
termination of employees entitled to

                                       15
<PAGE>

benefits under the Plans, the Company will notify the Recordkeeper, and the
Recordkeeper will update the Payment Schedule to indicate those Plan
Participants to whom benefits have become payable. Except as otherwise provided
herein, the Trustee shall make payments to the Plan Participants and their
beneficiaries in accordance with such Payment Schedule and shall pay such fees
and expenses, unless paid by the Company. 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 the Company.

     7.5 Entitlement to Benefits. The entitlement of a Plan Participant or his
         -----------------------
or her beneficiaries to benefits under the Plans shall be determined promptly by
the Committee, and any claim for such benefits shall be considered and reviewed
by the Committee under the procedures set out in the Plans. As soon as is
reasonably practicable following any such review or determination by the
Committee, the Committee shall give notice of its findings to the Recordkeeper,
together with updated information as needed, in order to permit the Recordkeeper
to make a final determination of the benefits to be paid. Upon notice of such
findings by the Committee, the Recordkeeper promptly will make a final
determination of the amounts payable and will notify the Committee.

     7.6 Payment of Benefits. The Company may make payment of benefits directly
         -------------------
to Plan Participants or their beneficiaries as they become due under the terms
of the Plans. The Company shall notify the Trustee and Recordkeeper of its
decision to make payment of benefits directly prior to the time amounts are
payable to Participants or their beneficiaries. Within thirty (30) days of
making of any such direct payment, the Company shall provide the Trustee and the
Recordkeeper with a certification, in a form acceptable to each, indicating the
date and amount of such direct payment of benefits by the Company.

     7.7 Notice of Benefits Payable. The Recordkeeper shall notify the Plan
         --------------------------
Participant or the beneficiary of a deceased Plan Participant that the Plan
Participant's benefits under a Plan have become payable. Such notice shall
include the amount of such benefits, the manner of payment (or, where
appropriate, the various payment options available) and the name, address and
social security number of the Plan Participant. Neither the Trustee nor the
Recordkeeper shall have any responsibility for determining whether any Plan
Participant or beneficiary has become entitled to any benefit under any of the
Plans, or whether any Plan Participant or beneficiary has died, and each of the
Trustee and the Recordkeeper shall be entitled to rely solely upon information
furnished by the Committee.

     7.8 Source of Payments. All benefits payable from the Trust Corpus to a
         ------------------
Plan Participant 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 Plan Participants under a Plan, the Recordkeeper shall

                                       16
<PAGE>

prepare and deliver to the Trustee a certification 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 Trust (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 and
deliver a certification to the Trustee and the Trustee shall thereupon
distribute the Trust Corpus to the Company.

    7.9  Tax on Amounts Held in Trust Prior to Distribution. 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 Plan Participants or any particular Plan Participant is subject
to federal income taxation on amounts held in trust hereunder prior to the
distribution to the Plan Participants or Plan Participant of such amounts, the
Trustee, on receipt by the Trustee of such opinion or notice of such
determination, shall pay to each Plan Participant the portion of the Trust
Corpus includable in such Plan Participant's federal gross income, less
applicable taxes. The Trustee shall not be required to obtain such opinion of
tax counsel unless the Internal Revenue Service, the Company, or the
Recordkeeper suggests to the Trustee that any of the Plan Participants may be
subject to income taxation on amounts held in the Trust prior to a distribution
hereunder and Trustee has doubts with respect thereto.

    7.10 Indemnification of Recordkeeper by Company. 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 and disbursements of counsel to the Recordkeeper) arising
out of or in connection with the performance by the Recordkeeper of its duties
hereunder. In the event that payment is required to be made to the Recordkeeper
from the Trust Corpus, as provided in Section 7.1 hereof, or this Section 7.10,
the Trustee shall promptly pay such amount and 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 this
Section 7.10, together with interest from the date of receipt of such notice
based upon the daily average of the prime rate charged by the Trustee, or its
United States banking affiliate. 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 Section 7.1 hereof or this Section 7.10.

    7.11 Resignation, Discharge & Replacement of Recordkeeper. 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, to the Company and

                                       17
<PAGE>

the Trustee, specifying a date (not less than sixty (60) 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 members of the Incumbent Board then serving on the Board of Directors (or,
if there are no members of the Incumbent Board then serving on the Board of
Directors, then by affirmative vote of at least three fourths (3/4) of the
current Board of Directors) shall appoint a successor recordkeeper, such
successor recordkeeper to become Recordkeeper hereunder upon the resignation
date specified in such notice. If a successor recordkeeper is not appointed
within sixty (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 members of the Incumbent Board then serving on the Board of
Directors (or, if there are no members of the Incumbent Board then serving on
the Board of Directors, then by affirmative vote of at least three fourths (3/4)
of the current Board of Directors) may at any time substitute a new recordkeeper
by giving fifteen (15) days' notice thereof to 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 Agreement.

     On or after a Change in Control, any successor recordkeeper appointed under
this Section 7.11, shall be an actuarial firm (or other third party providing
such services) by reputation and experience comparable to, and at least as
well-recognized as, the former Recordkeeper.

                                 ARTICLE VIII

            Payments to Trust Beneficiary When Company Is Insolvent

     8.1 Responsibilities of Trustee in Insolvency. At all times during the
         -----------------------------------------
continuance of this Trust as provided in Section 3.4 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:

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

         (b) Unless the Trustee has actual knowledge of the Company's
     Insolvency, or has received notice from the Company 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

                                       18
<PAGE>

     Insolvent. The Trustee may in all events rely on such evidence concerning
     the Company's solvency as may be furnished to the Trustee and that provides
     the Trustee with a reasonable basis for making a determination concerning
     the Company's solvency.

         (c) If at any time the Trustee has determined that the Company is
     Insolvent, the Trustee shall discontinue payments to Plan Participants or
     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 Plan Participants or their beneficiaries
     to pursue their rights as general creditors of the Company with respect to
     benefits due under the Plans or otherwise.

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

     8.2 Resumption of Discontinued Payments. Provided that there are sufficient
         -----------------------------------
assets, if the Trustee discontinues the payment of benefits from the Trust
pursuant to Section 8.1 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 the Company in lieu
of the payments provided for hereunder during any such period of discontinuance.

                                   ARTICLE IX

                             Payments to the Company

     9.1 Reversion of Funds to Company. Subject to Section 9.3, 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
six (6) months after delivery of the Required Funding Amount to the Trustee if
no Change in Control shall have occurred during such six-month period, and the
Board of Directors determines, and so certifies to the Trustee, that a Change in
Control is not imminent, pending, or reasonably expected to occur (or upon such
earlier certification by the non-employee members of the Board of Directors
acting unanimously), or upon the earlier termination of this Trust in a manner
consistent with Section 3.2 hereof. Such six-month 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 9.1, the Company shall
deliver a new Required Funding Amount (and a new Legal Defense Fund Amount, if
such amount has previously been returned to the Company) to the Trustee pursuant
to Article V above. The Company shall notify the Trustee of

                                       19
<PAGE>

the occurrence of a Potential Change in Control and Change in Control and the
Trustee may rely on such notice.

     9.2 Limitation Upon Company's Ability to Direct Payments. After the Trust
         ----------------------------------------------------
has become irrevocable, the Company shall have no right or power to direct the
Trustee to return to the Company or to divert to others any of the Trust assets
before all payments of benefits have been made to Plan Participants and their
beneficiaries pursuant to the terms of the Plans.

     9.3 Limitation on Reversion of Legal Defense Fund Amount. If any legal
         ----------------------------------------------------
claims have been instituted pursuant to Section 10.5, or the Trustee reasonably
believes that such claims are likely to be made, no part of the Legal Defense
Fund Amount shall be returned to the Company at a time that any such claim is
pending or any expense associated with such claim has not been reimbursed. In
addition, in no event shall the Legal Defense Fund Amount be returned to the
Company earlier than the expiration of the six-month period described in the
first sentence of Section 9.1.

                                    ARTICLE X

                  Powers, Duties & Responsibilities of Trustee

    10.1 Limitation of Liability. The duties and responsibilities of the
         -----------------------
Trustee shall be limited to those expressly set forth in this Trust Agreement,
and no implied covenants or obligations shall be read into this Trust Agreement
against the Trustee. 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 Agreement. 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.

    10.2 Maintenance of Administrative Records. 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 on a monthly basis commencing
on the first day of the month following the date this Trust Agreement was
created until the termination of the Trust (and as of the date of such
termination), an accounting with respect to the Trust Corpus as of the end of
such month (and as of the date of such termination). After a Change in Control
or a Potential Change in Control has occurred, and once the Required Funding
Amount has been contributed to the Trust, the Recordkeeper shall receive a
monthly accounting, and the Plan Participants may request an annual accounting
with respect to the Trust Corpus. Unless the Company (or any Plan Participant
after a Change in Control has occurred) shall have filed with the Trustee
written exceptions or objections to any such statement and account within one
hundred eighty (180) days after receipt thereof, the Company and all Plan
Participants 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

                                       20
<PAGE>

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 all Plan Participants were parties.

     The Trustee shall have the right, at the expense of the Trust, to apply at
any time to a court of competent jurisdiction for judicial settlement of any
account of the Trustee not previously settled as herein provided or for the
determination of any question of construction or for instructions. In any such
action or proceeding it shall be necessary to join as parties only the Trustee
and the Company (although the Trustee may also join such Plan Participants as it
may deem appropriate), and any judgment or decree entered therein shall be
conclusive.

     10.3 Reimbursement of Costs & Expenses. The Trustee shall be reimbursed by
          ---------------------------------
the Company for its reasonable expenses incurred in connection with the
performance of its duties hereunder (including, without limitation, legal fees
and expenses under Section 10.5 hereof) 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 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 Agreement to Trusts of a similar
character. The Trustee's entitlement to reimbursement hereunder shall not be
affected by the resignation or removal of the Trustee or the termination of the
Trust.

     10.4 Indemnification of Trustee by Company. The Company agrees to indemnify
          -------------------------------------
and hold harmless the Trustee from and against any and all liabilities, 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 Section 10.3 hereof, or under this Section 10.4, and not
previously paid by the Company shall be paid by the Company promptly upon demand
therefor 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
Section 10.3 hereof, or pursuant to this Section 10.4, 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 Section 10.3 hereof, or pursuant to this
Section 10.4.

     10.5 Institution of Litigation. Following a Change in Control, the Trustee
          -------------------------
is specifically authorized and required to take such action as may be necessary
or appropriate, including the institution

                                       21
<PAGE>

of litigation or other legal process, to enforce the Company's obligations
hereunder or under the Plans on behalf of either itself or the Plan Participants
(or their beneficiaries) and all claims for benefits by individual Plan
Participants against the Company, other than those pursued by a Plan Participant
pursuant to the last sentence of this Section 10.5 and those which the Trustee
reasonably believes to be frivolous, and shall not compromise or settle any such
claim, unless approved by the affected Plan Participants. Any expenses thus
incurred by the Trustee shall be paid or reimbursed by the Company pursuant to
Section 10.3 and 10.4 hereof. In addition, following a Change in Control, any
Plan Participant in Grade 18 or higher shall be entitled to be reimbursed for
any legal expenses he or she incurs in pursuing an independent legal proceeding
with respect to his or her rights under the Plans or this Trust in connection
with such Change in Control; provided, that such Plan Participant promptly
notifies the Trustee of his or her decision to pursue such proceeding, so as to
avoid duplication of expenses. In such event, the Trustee, in the exercise of
its sole discretion, may elect not to pursue a claim seeking similar relief
against the Company.

     10.6 Powers of Trustee. 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 upon direction of the Company, the 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. 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 Internal
Revenue Code.

                                   ARTICLE XI

                       Resignation and Removal of Trustee

     11.1 Resignation of Trustee. The Trustee may resign at any time by written
          ----------------------
notice to the Company, which shall be effective sixty (60) days after receipt of
such notice unless the Company and Trustee agree otherwise. If a Change in
