                           PETROLEUM HELICOPTERS, INC.
                       OFFICER DEFERRED COMPENSATION PLAN

         1. Purpose. The purpose of this Petroleum Helicopters, Inc. Officer
Deferred Compensation Plan (the "Plan") is to provide certain officers of
Petroleum Helicopters, Inc. and its subsidiaries and affiliates (hereinafter
collectively referred to as "PHI") designated by the Compensation Committee of
the Board of Directors of Petroleum Helicopters, Inc. (the "Committee") with an
opportunity to defer compensation in order to assist said officers in their
individual financial planning.

         2. Effective Date and Term of Plan and Effect on Other Plans. The
effective date of the Plan shall be January 1, 2001 and the Plan shall remain in
effect until terminated by the Board. This Plan shall supersede and replace
those certain officer deferred compensation plans listed on Schedule A, attached
hereto and made a part hereof (the "Old Plan(s)"), which Old Plans have been
terminated by the Board and, pursuant to such terminations, are null and void
and of no further force and effect as of the effective date of this Plan.

         3. Plan Administration. The Plan shall be administered by the
Committee. The Committee shall have full and final authority to interpret the
Plan; adopt, amend and rescind rules and regulations relating to the Plan,
determine the rights of employees and beneficiaries to benefits under the Plan;
and make all other determinations and take all other actions necessary and
advisable for the administration of the Plan.

         4. Deferral of Compensation.

                  4.1 Deferral Elections. Each officer of PHI (hereinafter
referred to as "Officer") may elect to defer up to twenty five percent (25%) of
his annual salary in one percent (1%) increments and up to one hundred percent
(100%) of any bonus received for services provided to PHI in one percent (1%)
increments up to twenty-five percent (25%) of said bonus and in five percent
(5%) increments thereafter. An Officer's annual salary and any bonus that may be
awarded are hereinafter collectively referred to as "Compensation."

                  4.2 Deferral Election Forms. An election to defer Compensation
hereunder shall be made by the Officer by means of a deferral election form
provided by PHI (the "Deferral Election Form"). Deferrals of Compensation shall
be effective only if the Officer makes a deferral election on a Deferral
Election Form and such Deferral Election Form is received by the Committee prior
to January 1 of the calendar year with respect to which said Compensation shall
be paid; provided, however, that if an officer of PHI first becomes eligible to
participate in the Plan after January 1 of a particular year, he may, in that
year only, make an election, within thirty (30) days after the date on which
such officer becomes eligible to participate in the Plan, to defer Compensation
to be paid for services that he will perform after the date of said election and
until the end of such year. An Officer shall make a new deferral election with
respect to each calendar year

                                       1
<PAGE>   2

for which he wishes to defer Compensation by completing and returning a Deferral
Election Form to the Committee prior to January 1 of the year to which the
deferral applies.

                  4.3 Revocation of Election. An Officer's deferral election
made pursuant to Section 4.2 of this Plan may be revoked only if such revocation
is in writing and received by the Committee prior to January 1 of the calendar
year with respect to which the services generating the Compensation that would
have been deferred will be performed. Any such revocation shall also be subject
to such other rules as may be established by the Committee. If an Officer
revokes an election to defer Compensation, the Officer may not again participate
in the Plan in the calendar year with respect to which the election to defer was
revoked.

         5. Deferred Compensation Accounts.

                  5.1 Establishment of Deferred Compensation Accounts. A
separate book reserve account shall be established for each Officer who executes
a Deferral Election Form (the "Deferred Compensation Account").

                  5.2 Unfunded Plan. This Plan is an unfunded arrangement,
maintained primarily to provide deferred compensation benefits to Participants
who are officers of PHI. Should PHI elect to set aside assets for any
obligations under this Plan through the purchase of mutual funds, such assets
shall not constitute funding for the Plan, shall be owned by PHI and shall be
subject to the claims of PHI's creditors. PHI reserves the right in its sole and
absolute discretion to sell any such assets, in whole or in part, at any time.
Notwithstanding anything to the contrary contained herein, PHI shall not be
required to purchase, set aside or segregate any assets of any kind to meet any
obligations that it may have hereunder; and any obligation of PHI to pay
benefits hereunder shall be an unsecured promise only, and a Participant's right
to enforce such obligation shall be solely as a general unsecured creditor of
PHI. Any and all references in this paragraph 5.2 to the Plan and to the
Deferred Compensation Accounts shall include the Old Plan and any deferred
compensation accounts established thereunder.

                  5.3 Crediting of Deferrals. An Officer's Deferred Compensation
Account shall be credited with an amount equal to that portion of the Officer's
Compensation that he has elected to defer pursuant to Section 4.1. Such credit
shall be made, as of the date such Compensation would otherwise have been paid
to the Officer. If an Officer participated in an Old Plan listed on Schedule A,
said Officer's Deferred Compensation Account shall, in consideration of the
cancellation of such Old Plan, also be credited, as of effective date of this
Plan, with the value of his deferred compensation account(s) under the Old Plan.
The value of said Officer's deferred compensation account(s) under the Old Plan
shall be determined as of the effective date of this Plan in the manner provided
for in the Old Plan.

                  5.4 Crediting Income.

                           (a) Each Officer's Deferred Compensation Account
created pursuant to Section 5.1 of this Plan shall be deemed to have been
invested and reinvested from time to time

                                       2
<PAGE>   3

in such Eligible Securities as the Officer shall designate from a list of
Eligible Securities provided by the Committee. The term "Eligible Securities"
shall mean (i) mutual funds; (ii) common and preferred stocks listed on a
national securities exchange; and (iii) corporate or governmental bonds, notes
and debentures that are either listed on a national securities exchange or for
which price quotations are published in newspapers of general circulation,
including "The Wall Street Journal."

                           (b) Each Officer shall have the right to designate
Eligible Securities that shall be deemed to have been purchased or sold for his
Deferred Compensation Account on the date of reference. In the case of any
deemed purchase, said Deferred Compensation Account shall be charged with a
dollar amount equal to the quantity and kind of securities deemed purchased
multiplied by the Fair Market Value of such Eligible Securities on the date of
reference and shall be credited with the quantity and kind of Eligible
Securities deemed to have been purchased. In the case of any deemed sale, said
Deferred Compensation Account shall be charged with the quantity and kind of
Eligible Securities deemed purchased multiplied by the Fair Market Value of such
Eligible Securities on the date of reference. For purposes of this Plan the term
"Fair Market Value" means, in the case of a listed security, the closing price
on the date of reference, or if there were no sales on such date, then the
closing price on the nearest preceding day on which there were sales; and in the
case of an unlisted security, the mean between the bid and asked prices on the
date of reference, or if no such prices are available on such date, then the
mean between the bid and asked prices on the nearest preceding day for which
such prices are available.

                           (c) Each Officer's Deferred Compensation Account
shall be credited with dollar amounts equal to cash dividends paid from time to
time upon the Eligible Securities deemed held therein. Dividends shall be
credited as of the payment date. Said Deferred Compensation Account shall
similarly be credited with interest payable on interest-bearing Eligible
Securities deemed held therein. Interest shall be credited as of the payment
date, except that in the case of a deemed purchase of interest-bearing Eligible
Securities, said Deferred Compensation Account shall be charged with the dollar
amount of interest accrued to the date of said deemed purchase and in the case
of deemed sales, the Deferred Compensation Account shall be credited with the
dollar amount of interest accrued to the date of the deemed sale.

                           (d) An Officer shall have the same rights and
obligations with respect to the deemed investment and reinvestment of dividends
and interest as he has with respect to the deemed investment and reinvestment of
the other amounts deemed held in his Deferred Compensation Account under the
terms of this Plan. Said Officer's Deferred Compensation Account shall be
equitably adjusted to reflect stock dividends, stock splits, recapitalizations,
mergers, consolidations, reorganizations and other changes affecting the
Eligible Securities deemed to be held therein.

                           (e) PHI shall not be required to purchase, hold, sell
or otherwise dispose of any of the Eligible Securities designated by an Officer;
provided, however, that if PHI

                                       3
<PAGE>   4

elects to purchase or sell any such Eligible Securities, said Officer's Deferred
Compensation Account shall be charged with brokerage fees and stock transfer
taxes with respect to such purchases and sales, but no other costs of PHI. PHI's
only obligation under this Plan is to make payments to each Officer who
participates herein measured as set forth herein. If PHI purchases Eligible
Securities to mirror the Participant's designations made under paragraph 5.4(b),
then the prices used in determining the Participant's Deferred Compensation
Account value shall be the actual purchase and sale prices of Eligible
Securities and not the closing prices referenced in that paragraph. To the
extent that PHI does, in its sole and absolute discretion, purchase any of the
Eligible Securities designated by an Officer, said Eligible Securities shall
remain the sole property of PHI, subject to the claims of PHI's general
creditors, and shall not be deemed to form a part of any Deferred Compensation
Account established under this Plan. Neither an Officer nor his legal
representative nor any beneficiary of said Officer shall have any right with
respect to any portion of his Deferred Compensation Account, other than the
right of an unsecured general creditor of PHI.

                           (f) As of the first date on which an Officer or an
Officer's estate is entitled to a distribution under this Plan (and on every
date on which a payment to an Officer is due thereafter if the Officer elected
to receive his distribution in installments), said Officer's Deferred
Compensation Account shall be valued by adding to the dollar amount credited to
the Deferred Compensation Account the Fair Market Value of the Eligible
Securities deemed to be held in said Deferred Compensation Account on the
payment date and deducting therefrom all brokerage fees and transfer taxes on
Eligible Securities deemed to be held in the Deferred Compensation Account.

                           (g) An Officer's Deferred Compensation Account shall
be reduced by the amount of any distributions made pursuant to this Plan.

                  5.5 Distribution of Amounts Credited to Deferred Compensation
Accounts. Except as provided in this Plan, amounts credited to an Officer's
Deferred Compensation Account shall be distributed in either a single lump sum
or annual installments (not to exceed twenty (20) installments), as designated
by the Officer in his Deferral Election Form. Distribution of the amounts
credited to a Deferred Compensation Account shall be made (in the case of a lump
sum payment) or commence (in the case of installment payments) thirty (30) days
following the date chosen by the Officer, which chosen date shall be no earlier
than January 2 of the calendar year following the year with respect to which an
Officer deferred his Compensation (or his annual salary only or his bonus only);
provided, however, that if an Officer ceases to be employed by PHI for any
reason other than death, said distribution may be made at any time after thirty
(30) days following the date that said Officer's employment ceases. If an
Officer elects to have the amounts credited to his Deferred Compensation Account
distributed in installments, the amount of the first installment shall be a
fraction of the value of the Officer's Deferred Compensation Account, the
numerator of which is one and denominator of which is the total number of
installments elected, and the amount of each subsequent installment shall be a
fraction of the value of the Deferred Compensation Account on the date preceding
each subsequent payment, the

                                       4
<PAGE>   5

numerator of which is one and the denominator of which is the total number of
installments elected minus the number of installments previously paid.

                  5.6 Distribution Upon Death. In the event of the death of an
Officer prior to the distribution in full of the amount credited to his Deferred
Compensation Account, the value of such Deferred Compensation Account shall be
determined as of the day immediately preceding distribution and such amount
shall be distributed in a single lump sum payment to the Officer's estate as
soon as administratively feasible following the officer's death.

                  5.7 Distribution Upon Unforeseeable Emergency. Upon the
application of an Officer (or the Officer's personal representative if the
Officer is unable to make such application), PHI shall have the power and
discretion to make a payment to the Officer (or his personal representative)
from the Officer's Deferred Compensation Account in the event of an
unforeseeable emergency caused by an unanticipated event beyond the control of
the Officer if such event will result in severe financial hardship to the
Officer if the payment is not granted. Any such payment shall be limited to the
amount necessary to meet said unanticipated emergency.

                  5.8 Statement of Account. Each Officer who has executed a
Deferral Election Form shall be provided with a statement of his Deferred
Compensation Account not less frequently than one (1) time per year.

         6. No Right To Continue As an Officer or an Employee. Neither this Plan
nor any action taken pursuant to this Plan shall constitute evidence of any
agreement or understanding, express or implied, that PHI will retain an Officer
in the capacity of an officer or as an employee in any capacity for any period
of time, or at any particular rate of compensation.

         7. No Trust. Except as provided in Section 8 of this Plan, nothing
contained herein and no action taken pursuant to the provisions hereof shall
create or be construed to create a trust of any kind for the benefit of any
Officer or any other person entitled to or claiming benefits hereunder.

         8. Change in Control.

                  8.1 Trust Upon a Change in Control. PHI shall, on or before
the date of a Change in Control, enter into a trust agreement (the "Trust
Agreement") with Whitney National Bank as trustee (the "Trustee") pursuant to
which PHI shall contribute to a trust (the "Trust") (i) Eligible Securities
actually purchased by PHI which reflect the Eligible Securities in Officers'
Deferred Compensation Accounts; or (ii) cash which shall be equal to the total
value of Officers' Deferred Compensation Accounts on the date preceding the
transfer date.

                  8.2 Form of Trust. The Trust Agreement shall be in the form of
the model trust agreement set forth in Internal Revenue Service Revenue
Procedure 92-64 or any successor to or replacement of such Revenue Procedure,
and may be substantially in the form of Exhibit 1,

                                       5
<PAGE>   6

attached hereto and made a part hereof, to the extent that said Exhibit 1
conforms to said Internal Revenue Service model trust agreement.

                  8.3 Trust Assets Subject to PHI's Creditors. All of the assets
of the Trust shall be subject to the creditors of PHI in the event of
insolvency. Any assets of the Trust remaining after all obligations with respect
to the Officers have been satisfied shall be paid to PHI.

                  8.4 Definition of "Change in Control." For purpose of this
Plan, the term "Change in Control" means:

                           (a) the purchase or other acquisition by any person,
entity or group of persons of beneficial ownership of forty-five percent (45%)or
more of either (i) PHI's outstanding shares of common stock; or (ii) the
combined voting power of PHI's then outstanding securities entitled to vote
generally; or

                           (b) the approval by the shareholders of PHI of a
reorganization, merger or consolidation with respect to which persons or
entities who were shareholders of PHI immediately prior to such reorganization,
merger or consolidation do not, immediately thereafter, own more than fifty
percent (50%) of the combined voting power entitled to vote; or

                           (c) the liquidation or dissolution of PHI or the sale
of all or substantially all of PHI's assets.

                  8.5 Successors Included. For purpose of this Section 8, any
reference to PHI includes any successor to PHI that results from a Change in
Control.

         9. Gender. Whenever used in this Plan, the masculine gender includes
the feminine and the feminine gender includes the masculine.

         10. Amendment, Modification, and Termination. The Board may at any time
terminate, amend or modify this Plan. No amendment, modification or termination
of the Plan shall in any manner adversely affect the rights of any Officer with
respect to amounts that have been credited to his Deferred Compensation Account
prior to such amendment, modification or termination.

         11. Nonalienation of Benefits. No Officer shall have any power or right
to transfer, assign, anticipate, pledge, hypothecate or otherwise encumber all
or any part of any amount credited to his Deferred Compensation Account or any
right to payment or benefits hereunder, which credits, benefits and rights are
expressly declared to be nonassignable and nontransferable.

         12. Notices. Unless otherwise expressly provided by applicable federal
law, if any, any notice, consent or demand required or permitted to be given
under the provisions of this Plan shall be in writing and shall be signed by the
party giving or making the same. If such notice, consent

its principal place of business at the time of the mailing of such notice,

                CERTAIN NONQUALIFIED DEFERRED COMPENSATION PLANS
                         OF PETROLEUM HELICOPTERS, INC.

         THIS AGREEMENT (the "Trust Agreement") made this _____ day of
__________, __________ by and between Petroleum Helicopters, Inc., a corporation
organized under the laws of the State of Louisiana, ("PHI") with its principal
place of business at 113 Borman Drive, Lafayette, Louisiana 70508 (the
"Company") and Whitney National Bank, a______________________, with its
principal place of business at ___________________, New Orleans, Louisiana
___________ (the "Trustee");

                                   WITNESSETH:

         WHEREAS, Company has adopted the nonqualified deferred compensation
plans listed in Appendix A, attached hereto and made a part hereof (the
"Plans"); and

         WHEREAS, Company has incurred or expects to incur liability under the
terms of such Plans with respect to the individuals participating in such Plans;
and

         WHEREAS, Company wishes to establish a trust (hereinafter called the
"Trust") and to contribute to the Trust assets that shall be held therein,
subject to the claims of Company's creditors in the event of Company's
Insolvency, as herein defined, until paid to Plan 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 hereto that this Trust
shall constitute an unfunded arrangement and shall not affect the status of the
Plans as unfunded plans 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;
and

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

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

         SECTION 1. ESTABLISHMENT OF TRUST.

         (a) Company hereby deposits with Trustee in trust __________ [INSERT
AMOUNT DEPOSITED], which shall become the principal of the Trust to be held,
administered and disposed of by Trustee as provided in this Trust Agreement.

                                       2
<PAGE>   12

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

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

         (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of Company and shall be used exclusively for
the uses and purposes of Plans participants and general creditors as herein set
forth. Plan participants and their beneficiaries shall have no preferred claim
on, or any beneficial ownership interest in, any assets of the Trust. Any rights
created under the Plans and this Trust Agreement shall be mere unsecured
contractual rights of Plan participants and their beneficiaries against Company.
Any assets held by the Trust will be subject to the claims of Company's general
creditors under federal and state law in the event of Insolvency, as defined in
Section 3(a) herein.

         (e) Upon a Change of Control, Company shall, by not later than the date
of a Change of Control, as defined herein, make an irrevocable contribution to
the Trust in an amount that is sufficient to pay each Plan participant or
beneficiary the benefits to which Plan participants or their beneficiaries would
be entitled pursuant to the terms of the Plans as of the date on which the
Change of Control occurred. To the extent that the Plans or any agreement
between the participants in and/or beneficiaries of the Plans and the Company
provide for a method of determining the amount to be contributed to the Trust,
said method shall be employed to determine the amount that shall be contributed
to the Trust pursuant to this Section 1(e).

         (f) 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 Trustee
to augment the principal to be held, administered and disposed of by Trustee as
provided in this Trust Agreement. Neither Trustee nor any Plan participant or
beneficiary shall have any right to compel such additional deposits.

         SECTION 2. PAYMENTS TO PLAN PARTICIPANTS AND THEIR BENEFICIARIES.

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

                                       3
<PAGE>   13

         (b) The entitlement of a Plan participant or his or her beneficiaries
to benefits under the Plans shall be determined by Company or such party as it
shall designate under the Plans, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plans.

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

         (d) Notwithstanding anything to the contrary contained herein or in the
Plans, (a) in the event that the Service prevails in its claim that amounts
contributed to and held in the Trust Fund, and/or earnings thereon, constitute
taxable income to participant or his beneficiary for any taxable year of him or
her, prior to the taxable year in which such contributions and/or earnings are
distributed to him or her, or (b) in the event that legal counsel satisfactory
to the Company, the Trustee and the applicable participant or his beneficiary
renders an opinion that the Service would likely prevail in such a claim, the
assets in the Trust Fund, to the extent constituting taxable income, shall be
immediately distributed to the participant or his beneficiary. For purposes of
this Section 2(d), the Service shall be deemed to have prevailed in a claim if
such claim is upheld by a court of final jurisdiction, or if the Trustee, based
upon an opinion of legal counsel satisfactory to the Company, the Trustee and
the participant or his beneficiary, fails to appeal a decision of the Service,
or a court of applicable jurisdiction, with respect to such claim, to an
appropriate Service appeals authority or to a court of higher jurisdiction
within the appropriate time period.

         SECTION 3. TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST
BENEFICIARY WHEN COMPANY IS INSOLVENT.

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

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

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

                                       4
<PAGE>   14

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

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

                  (4) Trustee shall resume the payment of benefits to Plan
participants or their beneficiaries in accordance with Section 2 of this Trust
Agreement only after Trustee has determined that Company is not Insolvent (or is
no longer Insolvent).

         (c) Provided that there are sufficient assets, if 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 Plan
participants or their beneficiaries under the terms of the Plans for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
participants or their beneficiaries by Company in lieu of the payments provided
for hereunder during any such period of discontinuance.

         SECTION 4. PAYMENTS TO COMPANY.

         Except as provided in Section 3 hereof, after the Trust has become
irrevocable, Company shall have no right or power to direct Trustee to return to
Company or to divert to others any of the Trust assets before all payment of
benefits have been made to Plan participants and their beneficiaries pursuant to
the terms of the Plans.

         SECTION 5. INVESTMENT AUTHORITY.

         In no event may Trustee invest in securities (including stock or rights
to acquire stock) or obligations issued by Company, other than a de minimis
amount held in common investment vehicles in which Trustee invests. All rights
associated with assets of the Trust shall be exercised by Trustee or the person
designated by Trustee, and shall in no event be exercisable by or rest with Plan
participants.

         SECTION 6. DISPOSITION OF INCOME.

                                       5

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.

         SECTION 8. RESPONSIBILITY OF TRUSTEE.

                  (a) Trustee shall act with the care, skill, prudence and
diligence under the circumstances then prevailing that a prudent person acting
in like capacity and familiar with such matters would use in the conduct of an
enterprise of a like character and with like aims, provided, however that
Trustee shall incur no liability to any person for any action taken pursuant to
a direction, request or approval given by Company which is contemplated by, and
in conformity with, the terms of the Plans or this Trust and is given in writing
by Company. In the event of a dispute between Company and a party, Trustee may
apply to a court of competent jurisdiction to resolve the dispute.

                  (b) If Trustee undertakes or defends any litigation arising in
connection with this Trust, Company agrees to indemnify Trustee against
Trustee's costs, expenses and liabilities (including, without limitation,
attorneys' fees and expenses) relating thereto and to be primarily liable for
such payments. If Company does not pay such costs, expenses and liabilities in a
reasonably timely manner, Trustee may obtain payment from the Trust.

in performing any of its duties or obligations hereunder.

                  (e) 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.

                  (f) Notwithstanding any powers granted to Trustee pursuant to
this Trust Agreement or to applicable law, Trustee shall not have any power that
