                            LYONDELL CHEMICAL COMPANY
                      NON-EMPLOYEE DIRECTORS BENEFIT PLANS
                                 TRUST AGREEMENT

     THIS AGREEMENT, as adopted as of January 1, 2002, between LYONDELL CHEMICAL
COMPANY (the "Company"), and WILMINGTON TRUST COMPANY (the "Trustee");

                                 R E C I T A L S

     A. Effective August 1, 2001, the Company and the Trustee enter into this
Agreement to create a Trust (defined under Section 1 of this Trust Agreement)
for purposes of the Lyondell Chemical Company Retirement Plan for Non-Employee
Directors, the Lyondell Chemical Company Elective Deferral Plan for Non-Employee
Directors and any benefit plans that may be established and maintained by the
Company for its non-employee directors after the effective date of this Trust
and that permit funding by this Trust. The benefit plans that may be funded by
this Trust are listed in Appendix A attached hereto and shall hereinafter be
referred to as the "Participating Plans".

     B. The amount and timing of benefit payments ("Benefits") to which the
participants of the Participating Plans (the "Trust Beneficiaries") are or may
become entitled under each of the Participating Plans are set forth in the
Participating Plans.

     C. The Company established this trust fund to assist it in accumulating the
amounts necessary to satisfy its contractual liability to pay Benefits under the
Participating Plans.

     D. The Company is obligated to pay all Benefits from its general assets to
the extent not paid by this Trust and this Trust Agreement shall not reduce or
otherwise affect the Company's continuing liability to pay Benefits from such
assets, except that the Company's liability shall be offset by actual benefit
payments made from this Trust.

     E. This trust is intended to be a "grantor trust" with the result that the
corpus and income of the Trust shall be treated as assets and income of the
Company pursuant to Sections 671 through 679 of the Internal Revenue Code of
1986, as amended (the "Code").
<PAGE>

     F. The Company intends that the Trust shall at all times be subject to the
claims of the Company's creditors as herein provided and that the Participating
Plans shall not be deemed funded within the meaning of the Employee Retirement
Income Security Act of 1974, as amended, ("ERISA") solely by virtue of the
existence of this Trust Agreement.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
the parties hereto agree as follows:

                                    SECTION 1

                              CREATION OF THE TRUST

     There is hereby established and continued with the Trustee a trust
consisting of all sums paid to it for purposes of the Participating Plans,
investments thereof and any earnings, appreciations or losses thereon, which,
less disbursements made by Trustee, and amounts paid to the Company as provided
in Section 2 of this Trust Agreement, are referred to herein as the "Trust" and
shall be dealt with as provided in this Trust Agreement. The Trust shall be held
for the exclusive purpose of providing payments to Trust Beneficiaries in
accordance with the provisions of the Participating Plans, and defraying
reasonable expenses of administration in accordance with the provisions of this
Trust Agreement until all such payments required by this Trust Agreement have
been made, subject to the provisions on the use of Funds under Section 2 of this
Trust Agreement, and to the requirement that the Trust shall at all times be
subject to the claims of the general creditors of the Company as set forth in
Sections 21.1 and 21.2 of this Trust Agreement. The Trustee shall have no duty
or authority to inquire into the correctness of amounts tendered to it or to
enforce the collection of any contribution by the Company.

         The Company shall direct the Trustee to establish a separate subtrust
("Subtrust") for each Plan to which the Trustee shall credit contributions it
receives which are earmarked for that Plan and Subtrust. Each Subtrust shall
reflect an undivided interest in assets of the trust fund and shall not require
any segregation of particular assets. When Subtrusts are established, all
contributions shall be designated by the Company for a particular Subtrust.
However, any contribution received by the Trustee which is not designated by the
Company for a particular Subtrust before a Change in Control shall be allocated
among the Subtrusts in proportion to each Participating Plan's pro rata interest
in the Trust, as calculated during the last Valuation. When a Subtrust

                                       2
<PAGE>

is established at a date subsequent to execution of this Agreement, the Trustee
shall allocate the Trust assets among the separate Subtrusts as directed by the
Company prior to a Change in Control.

     The Company may direct the Trustee, or the Independent Plan Administrator
may determine on its own initiative after a Change in Control, to maintain a
separate sub-account within each Subtrust for a Plan for each Participant who is
covered by the Subtrust. If so directed, each sub-account in a Subtrust shall
reflect an individual interest in assets of the Subtrust and, as much as
possible, shall operate in the same manner as if it were a separate Subtrust.

     The Trustee shall allocate investment earnings and losses and expenses of
the trust fund as of a valuation date among the Subtrusts in proportion to their
balances. Payments to creditors as directed by a court of competent jurisdiction
in the event of the Company's insolvency shall be charged against the Subtrusts
in proportion to their balances, except that payment of Plan benefits to a
Participant as a general creditor shall be charged against the Subtrust for that
Plan.

     Assets allocated to a Subtrust for one Plan may not be used to provide
benefits under any other Plans until all benefits under such Plan have been paid
in full, except that excess assets of a Subtrust may be transferred to other
Subtrusts.

                                    SECTION 2

                           LIMITATION ON USE OF FUNDS

     No part of the corpus of the Trust shall be recoverable by the Company,
borrowed by or against for the benefit of the Company or used for any purpose
other than for the exclusive purpose of providing payments to Trust
Beneficiaries in accordance with the provisions of the Participating Plans and
defraying reasonable expenses of administration in accordance with the
provisions of this Trust Agreement until all such payments required by this
Trust Agreement have been made; provided, however, that (i) nothing in this
Section 2 shall be deemed to limit or otherwise prevent the payment from the
Trust of (a) amounts described in Section 5 of this Trust Agreement, (b)
expenses and other charges as provided in Section 17 and 18 of this Trust
Agreement, or (c) the application of the Trust as provided in Sections 15.5 or
28 of this Trust Agreement, and (ii) the Trust shall at all times be subject to
the claims of the general creditors of the Company as

                                        3
<PAGE>

set forth in Section 21.1 and 21.2 of this Trust Agreement.

                                    SECTION 3

                                CHANGE IN CONTROL

     Section 3.1. General. Various provisions of this Trust Agreement provide
     ------------
for certain rights and obligations upon and following a Change in Control of the
Company.

     Section 3.2. Definition of "Change in Control". For purposes of this Trust
     ------------
Agreement, a "Change in Control" shall be deemed to have occurred as of the date
that one or more of the following occurs:

     (i) Individuals who, as of February 1, 1999, constitute the entire Board
("Incumbent Directors") cease for any reason to constitute at least a majority
of the Board; provided, however, that any individual becoming a director
              --------  -------
subsequent to the date hereof whose election, or nomination for election by the
Company's shareholders, was approved by a vote of at least a majority of the
then Incumbent Directors shall be considered as though such individual was an
Incumbent Director, but excluding, for this purpose any such individual whose
initial assumption of office occurs as a result of either an actual or
threatened election contest, as such terms are used in Rule 14a-11 under the
Securities Exchange Act of 1934, as amended or other actual or threatened
solicitation of proxies or consents by or on behalf of any Person (as defined
below) other than the Board;

     (ii) The stockholders of the Company shall approve any merger,
consolidation or recapitalization of the Company (or, if the capital stock of
the Company is affected, any subsidiary of the Company), or any sale, lease, or
other transfer (in one transaction or a series of transactions contemplated or
arranged by any party as a single plan) of all or substantially all of the
assets of the Company (each of the foregoing being an "Acquisition Transaction")
where (1) the shareholders of the Company immediately prior to such Acquisition
Transaction would not immediately after such Acquisition Transaction
beneficially own, directly or indirectly, shares or other ownership interests
representing in the aggregate eighty percent (80%) or more of (a) the then
outstanding common stock or other equity interests of the corporation or other
entity surviving or resulting from such merger, consolidation or
recapitalization or acquiring such assets of the Company, as the case may be, or
of its ultimate parent corporation or other entity, if any (in either case, the

                                        4
<PAGE>

"Surviving Entity"), and (b) the Combined Voting Power of the then outstanding
Voting Securities of the Surviving Entity or (2) the Incumbent Directors at the
time of the initial approval of such Acquisition Transaction would not
immediately after such Acquisition Transaction constitute a majority of the
Board of Directors, or similar managing group, of the Surviving Entity;
provided, however, that, notwithstanding the foregoing, a Change of Control
--------  -------
shall not be deemed to have occurred for purposes of this Subsection (ii) if
each of the following conditions are met: (a) the Acquisition Transaction is
between the Company and/or its Affiliates, on the one hand, and Millennium
Chemicals Inc. ("Millennium") and/or its Affiliates, on the other hand, (b) the
Company or an entity that was a wholly owned subsidiary of the Company prior to
the Acquisition Transaction has a class of equity securities registered under
Section 12 of the Securities Exchange Act of 1934, as amended, immediately after
completion of the Acquisition Transaction, (c) Millennium or an entity that was
a wholly owned subsidiary of Millennium prior to the Acquisition Transaction has
a class of equity securities registered under Section 12 of the Securities
Exchange Act of 1934, as amended, immediately after completion of the
Acquisition Transaction, and (d) as a result of the Acquisition Transaction, the
Company or its Affiliates own a greater percentage equity interest in Equistar
Chemicals, LP ("Equistar") than was owned, directly or indirectly, by the
Company immediately prior to such Acquisition Transaction;

     (iii) The stockholders of the Company shall approve any plan or proposal
for the liquidation or dissolution of the Company; or

     (iv) Any Person shall be or become the beneficial owner (as defined in
Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, as amended),
directly or indirectly, of securities of the Company representing in the
aggregate more than twenty percent (20%) of either (A) the then outstanding
shares of common stock of the Company ("Common Shares") or (B) the Combined
Voting Power of all then outstanding Voting Securities of the Company; provided,
                                                                       --------
however, that notwithstanding the foregoing, a Change in Control shall not be
-------
deemed to have occurred for purposes of this Subsection (iv):

     (1) Solely as a result of an acquisition of securities by the Company
     which, by reducing the number of Common Shares or other Voting Securities
     outstanding, increases (a) the proportionate number of Common Shares
     beneficially owned by any Person to more than twenty percent (20%) of the
     Common Shares then outstanding, or (b) the proportionate voting power
     represented by the Voting Securities beneficially

                                        5
<PAGE>

     owned by any Person to more than twenty percent (20%) of the Combined
     Voting Power of all then outstanding Voting Securities;

     (2) Solely as a result of an acquisition of securities directly from the
     Company, except for any conversion of a security that was not acquired
     directly from the Company; or

     (3) Solely as a result of a direct or indirect acquisition by Occidental
     Petroleum Corporation ("Occidental") or Millennium, or any Affiliate of
     either of them, of beneficial ownership of securities representing, (x) in
     the case of Occidental (with its Affiliates), no more than forty percent
     (40%), (y) in the case of Millennium (with its Affiliates), no more than
     forty percent (40%), and (z) in the case of Occidental (with its
     Affiliates) and Millennium (with its Affiliates) in the aggregate, no more
     than forty-nine percent (49%), of either (A) the then outstanding Common
     Shares or (B) the Combined Voting Power of all then outstanding Voting
     Securities of the Company, pursuant to or as contemplated under any
     agreement between the Company and Occidental and/or Millennium or
     Affiliates of either of them (including any subsequent related transaction
     or series of related transactions or acquisitions of Voting Securities of
     the Company by Occidental and/or Millennium or their Affiliates or
     assignees approved by the Incumbent Directors prior to the consummation of
     such transaction or series of related transactions) where, as a result of
     such transaction or series of related transactions, the Company or a
     Surviving Entity owns, directly or indirectly, a greater percentage equity
     interest in Equistar than was owned, directly or indirectly, by the Company
     immediately prior to such transaction or series of related transactions;

     provided, further, that if any Person referred to in paragraph (1) or (2)
     of this Subsection (iv) shall thereafter become the beneficial owner of
     additional shares or other ownership interests representing one percent
     (1%) or more of the outstanding Common Shares or one percent (1%) or more
     of the Combined Voting Power of the Company (other than (x) pursuant to a
     stock split, stock dividend or similar transaction or (y) as a result of an
     event described in paragraph (1), (2) or (3) of this Subsection (iv)), then
     a Change in Control shall be deemed to have occurred for purposes of this
     Subsection (iv).

                                        6

                                        7
<PAGE>

     Section 3.4. For purposes of Section 3.1 of this Trust Agreement:
     -----------

          A. "Combined Voting Power" shall mean the aggregate votes entitled to
     be cast generally in the election of the Board of Directors, or similar
     managing group, of a corporation or other entity by holders of then
     outstanding Voting Securities of such corporation or other entity.

          B. "Person" shall mean any individual, entity (including, without

     the Company or LYONDELL-CITGO Refining LP ("LCR") or Equistar or any of

          C. "Voting Securities" shall mean all securities of a corporation or

                                    SECTION 4

                         INDEPENDENT PLAN ADMINISTRATOR

     Various provisions of this Trust Agreement refer to the term "Independent
Plan Administrator" which shall mean, unless stated otherwise in a specific
provision of this Trust Agreement, and, except as provided below, an entity
which is unrelated to, and unaffiliated with, the Company, and which, prior to a
Change in Control has accepted in writing the position of Independent Plan
Administrator under this Trust Agreement. The Independent Plan Administrator
shall not be considered to be related to or affiliated with the Company solely
as a result of an agreement between the Independent Plan Administrator and the
Company to provide individual financial counseling services to specified Company
executives or to provide financial counseling services to survivors of deceased
Company employees. The Independent Plan Administrator shall be appointed by the
Company and shall have its

                                        8
<PAGE>

duties specified in an agreement executed by the Company and the Independent
Plan Administrator prior to a Change in Control. The Trustee shall be given
advance written notification of such appointment by the Company. Following a
Change in Control, if the Company had failed to designate an Independent Plan
Administrator prior to a Change in Control, the Independent Plan Administrator
shall be appointed by the Trustee following a Change in Control and shall have
its duties specified in an agreement executed by the Trustee and the Independent
Plan Administrator. In the event the Independent Plan Administrator fails to
act, provides services to the Company other than in its capacity as Independent
Plan Administrator other than as provided above, or resigns, the Company prior
to a Change in Control, or the Trustee after a Change in Control, shall retain a
successor Independent Plan Administrator. Notwithstanding any other provision of
this Trust Agreement, the Trustee shall be responsible only for the prudent
selection of an Independent Plan Administrator after a Change in Control (i)
following notice by the Company or the Independent Plan Administrator of
disqualification of the Independent Plan Administrator through the provision of
services to the Company other than in its capacity as Independent Plan
Administrator, (ii) upon resignation or failure to act by the Company-appointed
Independent Plan Administrator, or (iii) in the event the Company failed to
appoint an Independent Plan Administrator prior to a Change in Control. The
Trustee shall be entitled to conclusively rely on the determinations of a
qualified Independent Plan Administrator.

                                    SECTION 5

                                EXCESS REVERSION

     Prior to a Change in Control, upon a determination that the assets of the
Trust have a value exceeding one hundred twenty-five percent (125%) of the
actuarial present value of accrued but unpaid benefits of the Participating
Plans, considered on the basis of assets being allocated to Participating Plans,
all or a portion of the amount of such assets which constitute the "Excess
Reversion" (as defined below) may be repaid to the Company upon direction of the
Company. However, prior to any such repayment, the Company must deliver to the
Trustee a certified statement by an actuary who is an Enrolled Actuary under
ERISA and who is not affiliated with the Company of (i) the amount equal to one
hundred (100%) percent of the actuarial present value of the accrued but unpaid
benefits under the Participating Plans, calculated on an individual plan basis,
as described above, (the "Certified Benefit Values"), (ii) the value of the
Trust assets, allocated to each

                                        9
<PAGE>

Participating Plan, as described above, and (iii) the amount, if any, by which
the value of the Trust assets under (ii) exceeds the Certified Benefit Values
under (i), and (iv) the amount, if any, by which the value of the Trust assets
under (ii) exceeds one hundred twenty-five (125%) percent of the Certified
Benefit Values (the "Excess Reversion"). The actuary shall make each
determination required to prepare the certified statement based on reasonable
factors, assumptions and tables (as determined solely by such actuary). The
Trustee shall repay assets of the Trust to the Company as directed by the
Company and in an amount up to but not greater than the Excess Reversion. Any
repayment of assets of the Trust to the Company may be made only prior to a
Change in Control and shall be made within thirty (30) days (or as soon as
practicable) after the later of the Trustee's receipt of the certified statement
by the actuary and the Company's direction to make such a payment. Any separate
allocations of assets pursuant to this Section 5 shall be solely for the purpose
of completing the valuation tests described in this Section and shall not
reflect any legal commitment of assets to any Trust Beneficiary under a
particular Participating Plan.

                                    SECTION 6

                         AUTHORITY OF INVESTMENT OFFICER

     Prior to a Change in Control, the Trustee shall be subject to the direction
of the Investment Officer (as defined below) of the Company with respect to the
investment of the assets of the Trust. Unless the Company and the Trustee have
mutually agreed in a separate writing that the Trustee shall have and exercise
investment discretion with respect to all or a portion of the assets of the
Trust, the Company shall have complete discretion with respect to the investment
of such assets at all times prior to a Change in Control, and shall direct the
Trustee accordingly. From time to time, the Trustee shall be notified in a
writing signed by an officer of the Company of the person or persons
constituting the "Investment Officer" for purposes of this Section and the
Trust. In each such notice, the Company shall warrant that all directions given
by the Investment Officer are proper. The Trustee shall have no responsibility
to review, or to consider the propriety of holding or selling any life
insurance, retirement income or annuity policies or contracts.

     Notwithstanding the Company's discretion to invest the Trust assets, the
Company shall not exercise this discretion to reacquire part or all of the
assets held in the Trust by substitution of or exchange for any other property
held by the Company directly or indirectly through any third party, related or

                                       10

unrelated, and whether or not the property is equivalent, marketable, liquid, or
secured.

investments specified in Section 14 of this Trust Agreement ("Investment Grade
Securities") with the power to appoint any independent investment manager to

Trustee, (ii) the Independent Plan Administrator shall have sole power on and
after a Change in Control regarding the management, including the purchase, sale

contracts, (iii) any such powers of the Trustee or Independent Plan
Administrator described above may not be delegated, in whole or in part, after a
Change in Control to the Company or any affiliate of the Company, and (iv) the
Trustee shall not be required to liquidate any investments that were made
pursuant to the directions of the Investment Officer that are not Investment

     A. To invest and reinvest the Trust, without distinction between principal
     and income, in any form of domestic or foreign real or personal property,
     whether or not productive of income or consisting of wasting assets,

                                    SECTION 8

                   ADDITIONAL POWERS AND DUTIES OF THE TRUSTEE

     Following a Change in Control, should the Company attempt to enjoin any
benefit payment (other than for reasons of manifest error) that the Trustee has
been directed to make under the terms of this Trust Agreement, the Trustee shall
commence legal action to allow such payment. The Trustee may withdraw from the
Trust assets any amounts it deems necessary to pay legal expenses, including
attorneys' fees, incurred in the course of such legal action. Under no
circumstances shall the Trustee be required to make such payments for benefits
or expenses from any source other than the Trust. Except as otherwise limited by
Section 6, the Trustee shall also have the following powers:

     A. To cause any asset, real or personal, to be held in a corporate
     depository or federal book entry account system or registered in the
     Trustee's name or in the name of a nominee or in such other form as the
     Trustee deems best without disclosing the trust relationship; provided,
     however, that nothing contained in this Section shall be deemed to relieve
     the Trustee of any custodial responsibility allocated to it

                                       13
<PAGE>

     under this Trust Agreement;

     B. To employ agents in the management of the Trust, including employees of
     the Company and its subsidiaries and affiliates prior to a Change in

                                    SECTION 9

                        INSURANCE POLICIES AND CONTRACTS

     Prior to a Change in Control, the Company reserves the right to transfer
life insurance, retirement income or annuity policies or contracts, to the
Trust, regardless of the nature or type of such contract and regardless of the
Company's interest in, or power to direct the investments under, such policies
or contracts, or prior to a Change in Control, to direct the Trustee to purchase
any such policies or contracts, and following a Change in Control the
Independent Plan Administrator shall have the same powers regarding such
insurance policies and contracts. Any such policy or contract shall be an asset
of the Trust subject to the claims of the Company's creditors in the event of
insolvency, as specified in Sections 21.1 and 21.2 of this Trust Agreement. The
proceeds of any life insurance policy shall, upon the death of the insured, be
paid to the Trust. The Trustee shall be under no duty to question any direction
of the Company or the Independent Plan

                                       14
<PAGE>

Administrator, to review the form of any such policies or contracts or the
selection of the issuer thereof, or to make suggestions to the Company, the
Independent Plan Administrator or to the issuer thereof with respect to the form
of such policies or contracts prior to a Change in Control, or to question any
such directions, to review such policies, forms or selections or to make such
suggestions to the Independent Plan Administrator following a Change in Control.
Prior to a Change in Control, the Company may direct the Trustee to exercise the
powers of the contract holder under any such policies or contracts, and the
Trustee shall exercise such powers only upon the direction of the Company.
Following a Change in Control, the Independent Plan Administrator may direct the
Trustee to exercise the powers of the contract holder under any such policies or
contracts and the Trustee shall exercise such powers only upon direction of the
Independent Plan Administrator. Notwithstanding anything to the contrary
contained in any Participating Plan, the Trustee (i) shall be fully protected in
acting in accordance with written directions of the Company prior to a Change in
Control and with the written directions of the Independent Plan Administrator
following a Change in Control, and (ii) shall be under no liability for any loss
of any kind that may result by reason of any action taken or omitted by it in
accordance with such direction of the Company or the Independent Plan
Administrator, or by reason of inaction in the absence of such written
directions from the Company or the Independent Plan Administrator. No insurance
carrier shall for any purpose be deemed a party to this Trust Agreement or be
responsible for the validity or sufficiency hereof. Notwithstanding the fact
that it may have knowledge of the terms of this Trust, the obligations of such
insurance carrier shall be measured and determined solely by the terms and
conditions of the policies or contracts issued by it. Any such insurance carrier
shall not be under any obligation to any person, partnership, corporation, trust
or association other than as stated in such policies or contracts.

                                   SECTION 10

                           PARTICIPATING PLAN RECORDS

     A separate written record of the accrued and vested benefit, as applicable,
for each Trust Beneficiary of each Participating Plan, based on a certified
listing provided by the Company prior to a Change in Control and by the
Independent Plan Administrator following a Change in Control, shall be
maintained. The Company or the Independent Plan Administrator, as applicable,
shall provide such certified listing at least once each calendar year to the
Trustee.

                                    VALUATION

     The Trust shall be revalued by the Trustee at current values, as determined
by the Trustee, as of the last business day of each calendar year and as of such
additional dates as the Trustee and Company shall determine to be appropriate
("Valuation"). The Company prior to a Change in Control and the Independent Plan
Administrator following a Change in Control annually shall provide a
certification of value for each life insurance, retirement income or annuity
policy or contract held as an asset of the Trust. The Trustee may rely upon the
certification of value received from the Company prior to a Change in Control or
the Independent Plan Administrator following a Change in Control for each such
policy or contract held as an asset of the Trust.

                                   SECTION 12

         PARTICIPANT RECORDS PRIOR TO AND FOLLOWING A CHANGE IN CONTROL

     Section 12.1. In addition to the records maintained under Section 10, the
     -------------
Company shall maintain a separate written record that reflects for each Trust
Beneficiary, the Trust Beneficiary's vested benefits under each Participating
Plan and the portion of the Trust or Subtrust allocated to such Trust
Beneficiary (a "Participant Record"). Prior to a Change in Control, the Trustee
shall certify to the Company the results of each Valuation. Following receipt of
a Valuation, each Participant Record shall be equitably adjusted by the Company
to reflect its share of the income, expense, appreciation and depreciation since
the preceding Valuation date. Such Participant Records shall be maintained
solely for record keeping purposes prior to a Change in Control, without any
legal entitlement of a Trust Beneficiary to amounts allocated to his or her
Participant Record.

     Section 12.2. On and after a Change in Control, the Independent Plan
     -------------
Administrator (i) shall continue to maintain the Participant Records and the
records described in Section 10 of this Trust Agreement, (ii) shall thereafter
be solely responsible for the updating of such Participant Records and for
requesting the Trustee to make any additional Valuations the Trustee and
Independent Plan Administrator deem appropriate, and (iii) shall be entitled to
rely on the most recent certified listing delivered by the Company to the
Trustee prior to a Change in Control in the

                                       16
<PAGE>

maintenance and updating of such Participant Records following a Change in
Control. No new Participant Records may be established following a Change in
Control. The Independent Plan Administrator may, but is not required to, rely on
any certified listing provided by the Company pursuant to Section 10 following a
Change in Control. Following a Change in Control, the sole source of Trust
assets from which the Independent Plan Administrator may direct that a Trust
Beneficiary's Benefits be paid to the extent the Trustee, rather than the
Company, pays the Benefits shall be that portion of the assets of the Trust or
Subtrust allocated to the Participant Record of such Trust Beneficiary.

                                   SECTION 13

                                TRUSTEE ACCOUNTS

     Within 120 days after the close of each fiscal year of the Trust and any
other period agreed upon by the Trustee and the Company, and within ninety (90)
days of the date of the removal or resignation of the Trustee, the Trustee shall
file with the Company a written account ("Trustee Account") setting forth all
investments, receipts, disbursements, withdrawals and other transactions
effected by it during the period from the date of its last such Trustee Account
and a list of the assets of the Trust at the close of such period. Such Trustee
Account may be in the form of monthly or quarterly statements which taken
together reflect the matters set forth in the preceding sentence. As between the
Company and the Trustee, the Trustee shall be forever released and discharged
from all liability with respect to the propriety of acts and transactions shown
in such Trustee Account following a Change in Control, and shall be forever
released and discharged from all liability with respect to the propriety of acts
and transactions shown in such Trustee Account prior to a Change in Control
except with respect to any such act or transaction as to which the Company
shall, within a 90-day period of receipt of the Trust Account, file written
objections with the Trustee and except that no such accounting shall foreclose
any liability of the Trustee to the Company arising under Section 23.3 of this
Trust Agreement.

                               INVESTMENT OF CASH

     Prior to a Change in Control, the Trustee shall keep any cash held
hereunder from time to time on deposit in its own banking department or
elsewhere as the Trustee elects, consistent with instructions provided by the
Investment Officer of the Company regarding specific types of permissible
investments and permissible depositories. Prior to a Change in Control, in the
absence of contrary instructions from the Investment Officer, and following a
Change in Control, in the absence of contrary instructions from the Independent
Plan Administrator regarding insurance, retirement income or annuity policies or
contracts, and anything herein to the contrary notwithstanding, the Trustee,
without obtaining any prior approvals, may at its discretion invest cash
balances held by the Trustee from time to time in deposits in its own banking
department, in short-term cash equivalents having ready marketability, including
but not limited to U.S. Treasury bills, commercial paper rated not less than
A1/P1 (including such forms thereof as may be available through the Trustee's
own trust department), certificates of deposit, and similar type securities,
having a maturity of 18 months or less, including participation in common or
collective funds composed thereof. Prior to a Change in Control, the Trustee may
sell any such short-term investments as may be necessary to carry out the
instructions of the Investment Officer of the Company regarding more permanent
type investments or to permit any distributions or transfers directed hereunder.
The Trustee may make any such sales it deems appropriate following a Change in
Control, including sales necessary to carry out the instructions of the
Independent Plan Administrator.

                             PAYMENTS BY THE TRUSTEE

     Section 15.1. The establishment of the Trust and the payment or delivery to
     -------------
the Trustee of money or other property acceptable to the Trustee shall not vest
in any Trust Beneficiary any right, title or interest in or to any assets of the
Trust.

     Section 15.2. The Trustee shall be directed as to the amount, timing, and
     -------------
form of benefits to be paid to any Trust Beneficiary. Prior to a Change in
Control, the Company shall so direct the Trustee and by giving such directions
shall be deemed to warrant their propriety. Following a Change in Control, the
Independent

                                       18
<PAGE>

Plan Administrator shall so direct the Trustee and by giving such directions,
shall be deemed to warrant their propriety.

     Section 15.3. The Trustee shall withhold all or any part of any payment for
     -------------
the payment of any tax liability and the Trustee shall discharge such liability
as and when directed by the Company prior to a Change in Control and by the
Independent Plan Administrator following a Change in Control. All withholding,
related filings and reports are the responsibility of the Company.

     Section 15.4. The Company intends to make benefit payments from its assets
     -------------
as it deems appropriate, in its sole discretion, provided, that, notwithstanding
this intent, if the Trust is not sufficient, before or after a Change in
Control, to make one or more payments of Benefits to the Trust Beneficiaries
under the relevant Participating Plan, the Company shall make the balance of
each such payment as it falls due.

     Section 15.5. 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 the time for appeal or
protest of which has expired, or the receipt by the Trustee of an unqualified
opinion of tax counsel selected by the Trustee or Company, which determination
determines, or which opinion concludes, that any Trust Beneficiary is subject to
federal income taxation on amounts held in trust to pay Benefits hereunder prior
to the distribution to the Trust Beneficiary of such Benefits, the Trustee
shall, on receipt by the Trustee of such opinion or actual notice of such
determination, pay to such Trust Beneficiary the portion of the Trust corpus
includible in such Trust Beneficiary's federal gross income, and the Trust
Beneficiary's Benefits shall be canceled to the extent of such payment, provided
that the amount, form and timing of such payments and the amount and method of
such cancellation shall be as directed by the Company prior to a Change in
Control and by the Independent Plan Administrator following a Change in Control.

                                   SECTION 16

                       DETERMINATION OF CHANGE IN CONTROL

     The Company shall immediately notify the Trustee in writing of the
occurrence of a Change in Control as the result of any event specified in
Section 3.1 of this Trust Agreement. If the Trust Department of the Trustee
receives written notice from a third party (including the Company's outside
auditors) of the alleged occurrence of a Change in Control as the result of any

                                       19
<PAGE>

event specified in Section 3.1 of this Trust Agreement, the Trustee shall
request the Company to confirm or deny such occurrence and the Company shall
make such confirmation or denial within forty-five (45) days following receipt
of the Trustee's request. In order to deny that a Change in Control as the
result of any event specified in Section 3.1 of this Trust Agreement has
occurred, the Company shall provide with its notice a certificate, in a form
reasonably satisfactory to the Trustee, from an independent accounting firm,
which firm may be the accounting firm engaged by the Company to be its outside
auditors, certifying that a Change in Control as the result of an event
specified in Section 3.1 of this Trust Agreement has not occurred. Pending the
Company's response, the Trustee shall not repay, pursuant to Section 5 of this
Trust Agreement, any assets of the Trust to the Company and no new Trust
Beneficiaries may be added to the Trust. The Trustee shall be entitled to
conclusively rely upon such confirmation or denial.

                                   SECTION 17

                     TRUSTEE COMPENSATION AND TRUST EXPENSES

     The Trustee shall be paid such reasonable compensation for its service as
Trustee as shall from time to time be agreed upon by Company and Trustee. This
compensation and all expenses incurred by the Trustee in the management and
protection of the Trust, including administration, accounting and legal fees,
shall be reimbursed by the Company within 30 days after the Company's receipt of
a bill from the Trustee for any fees and expenses paid from the Trust assets. To
the extent the Company fails to reimburse the Trustee, this compensation and
extraordinary and non-recurring expenses shall be charged by the Trustee against
the Trust.

                                   SECTION 18

                           PAYMENT OF TAXES BY TRUSTEE

     Prior to a Change in Control, to the extent that any taxes levied or
assessed upon the Trust are not paid by the Company, the Trustee shall pay such
taxes out of the Trust as directed by the Company. The Trustee shall, if
requested by the Company prior to a Change in Control, and solely in its
discretion following a Change in Control, contest the validity or amount of any
tax assessment, claim or demand respecting the Trust or any part thereof. The
Company itself may contest the validity of any such taxes prior to a Change in
Control.

                              CUSTODIANS AND AGENTS

     When so instructed by the Company prior to a Change in Control with respect
to Trust assets for which the Company has investment responsibility, and at the
Trustee's sole discretion with respect to assets for which the Trustee has
investment responsibility, the Trustee shall deposit any assets held by it with
a custodian, which may not include the Company or an affiliate of the Company,
and the Company shall hold harmless and defend the Trustee against any liability
arising or asserted to arise out of the Trustee's compliance with directions
under this Section 19 of this Trust Agreement.

                         LIABILITY FOR BENEFIT PAYMENTS

     The Company shall remain primarily liable to pay Benefits under the
Participating Plans. However, the Company's liability under the Participating
Plans shall be reduced or offset to the extent Benefit payments are made from
the Trust.

purposes of this Trust Agreement in the event of the following:

     A. the Company's inability to pay debts as they mature;

     B. a general assignment for the benefit of the Company's creditors;

     C. the voluntary commencement by the Company of any proceeding under Title
     11 of the United States Code or any

     other law of any jurisdiction for the relief, liquidation or rehabilitation
     of debtors (all of which proceedings are hereinafter collectively referred

     D. the making of an admission by the Company of any of the material
     allegations of, or consenting to, or acquiescing in, a petition,
     application, motion or complaint commencing an Insolvency Proceeding or the
     seeking by the Company of the appointment of, or the taking of possession
     by, a receiver, custodian, trustee, liquidator or similar official of or
     for it or for a substantial part of its assets;

     E. the involuntary commencement of an Insolvency Proceeding against the
     Company which is not fully stayed, timely controverted or dismissed within
     one hundred twenty (120) days after the filing thereof; or

     F. the appointment of, or the taking of possession by, a receiver,
     custodian, trustee, liquidator or similar official of or for the Company or
     of or for all or substantially all of its assets.

     If the Trust Department of the Trustee receives a written allegation from a
third party that the Company has become insolvent, the Trustee shall appoint an
independent accounting firm to determine within sixty (60) days whether the
Company is insolvent under the terms of this Trust Agreement and, pending such
determination, the Trustee shall discontinue payments of Benefits to Trust
Beneficiaries, shall hold the Trust assets for the benefit of the Company's
general creditors, and shall resume payments of Benefits to Trust Beneficiaries
only after such independent accounting firm, has determined that the Company is
not insolvent (or is no longer insolvent, assuming the independent accounting
firm initially determined the Company to be insolvent) or after receipt of an
order of a court of competent jurisdiction. In making its determination, such
independent accounting firm, may rely on a letter from the Company's Controller,
or its Independent Auditors, or on relevant information concerning the Company's
solvency which has been furnished to the Trustee by any other person.
Notwithstanding any other provision of this Trust Agreement, the Trustee shall
be responsible only for the prudent selection of the independent accounting
firm, and shall conclusively rely on such firm's determination. Nothing in this
Trust Agreement shall in any way enlarge or diminish the rights of the Trust
Beneficiaries in the event the Company is insolvent to pursue their rights as
general creditors of the Company with respect to their Benefits or otherwise.

the determination of insolvency by an independent accounting firm as provided in
Section 21.1 of this Trust Agreement, the Trustee shall deliver any
undistributed principal and income in the Trust to satisfy claims of the

have been made to such Trust Beneficiary in accordance with the relevant
Participating Plan during the period of such discontinuance, less the aggregate
amount of payments of Benefits made to such Trust Beneficiary by the Company
during any such period of discontinuance. Prior to a Change in Control, the
Trustee shall be directed as to the amount, timing, form and payee of all such
payments by the Company. Following a Change in Control, the Trustee shall be so
directed by the Independent Plan Administrator.

                              AND INDEMNIFICATIONS

     Section 23.1. Trustee shall perform all of its functions hereunder (i) with
     -------------
the care, skill, prudence, and diligence which under the circumstances then
prevailing a prudent man acting in a like capacity and familiar with such

from time to time by law, and shall not be liable for any conduct on its part
(including reliance on advice of counsel) which conforms to that standard.

     Section 23.2. The Company (which has the authority to do so under the laws
     -------------
of its state of incorporation) shall indemnify the Trustee and defend it and
hold it harmless from and against any and all direct liabilities, losses,
claims, suits or expenses (including attorney's fees) of whatsoever kind and
nature which may be imposed upon, asserted against or incurred by the Trustee at
any time by reason of its carrying out its responsibilities or providing
services hereunder or by reason of any act or failure to act under this Trust
Agreement, except to the extent that any such liability, loss, claim, suit or
expense arises directly from the Trustee's gross negligence or willful
misconduct in the performance of responsibilities specifically allocated to it
under this Trust Agreement. The provisions of this Section 23.2 shall survive
the termination of this Trust Agreement.

     Section 23.3. The Trustee (which has the authority to do so under the laws
     -------------
of its state of incorporation) shall indemnify the Company and defend it and
hold it harmless from and against any and all direct liabilities, losses,
claims, suits or expenses (excluding indirect, consequential special and

which may be imposed upon, asserted against or incurred by the Company at any
time directly by reason of the Trustee's gross negligence or willful misconduct
in the performance of responsibilities specifically allocated to it under this
Trust Agreement. The provisions of this Section 23.3 shall survive the
termination of this Trust Agreement.

     Prior to a Change in Control, Trustee may be removed by the Company at any
time upon not less than thirty (30) days' written notice. The Trustee may resign
at any time prior to or following a Change in Control, upon not less than ninety
(90) days' written notice. In either case, such notice may be wholly or
partially waived by the party to whom it is due. Upon Trustee's removal or
resignation prior to a Change in Control, the Company shall appoint a successor
Trustee, who shall have no responsibility for the acts or omissions of any
predecessor trustee, and upon the Trustee's resignation following a Change in
Control the Trustee shall petition a court of competent jurisdiction to name a
successor trustee which in no event may be the Company or an affiliate of the
Company or a successor thereto; provided, however, that the successor trustee in
either case shall have the same powers and duties as those conferred upon the
Trustee hereunder, and upon acceptance of such appointment by the successor
Trustee, the Trustee shall assign, transfer and pay over to such successor
Trustee the Trusts and properties then constituting the Trust. If the Company
fails within a reasonable time to name a successor Trustee or otherwise direct
proper disbursement of the Trust prior to a Change in Control, the Trustee may
apply to any court of competent jurisdiction for appropriate relief. The Trustee
may in any event reserve such reasonable sum of money as it may deem advisable,
to provide for any charges against the Trust for which it may be liable, and for
payment of its fees and expenses in connection with the settlement of its
account or otherwise. Any balance of such reserve remaining after the payment of
such fees and expenses shall be paid over as aforesaid.

     If a Participating Plan is wholly or partially terminated prior to a Change
in Control, the Trustee shall disburse the portion of the Trust affected by the
termination as directed by the Company. If a Participating Plan is wholly or
partially terminated following a Change in Control, Trustee shall disburse the
portion of the Trust affected by the termination as directed by the Independent
Plan Administrator.

     Section 27.1. Prior to a Change in Control, the Company may amend this

Trust Agreement by an instrument in writing signed by an authorized officer of

payments under Sections 2 or 5 of this Trust Agreement, or defrayal of
reasonable expenses of administering the Participating Plans. The Trustee's
consent shall be required for any amendment affecting its duties,
responsibilities or rights. No amendment affecting the duties, responsibilities
or rights of the Trustee shall take effect until thirty (30) days after a copy
of said amendment is furnished to the Trustee or, if the Trustee gives notice of
resignation within such 30 day period, until the resignation becomes effective,

                              TERMINATION OF TRUST

     Section 28.1. Prior to a Change in Control, the Company may not terminate
     -------------
this Trust for reasons other than those provided in (A) and (B) below.
Otherwise, this Trust shall be irrevocable. Removal or resignation of a Trustee
pursuant to Section 24 shall not be deemed a termination of this Trust
Agreement.

     A. This Trust will terminate if a federal court determines, after
     exhaustion of all appeals, that the Trust causes any of the Participating
     Plans to cease to be "unfunded" under the provisions of ERISA.

     B. The Company may terminate this Trust if the Company determines, based on
     advice of legal counsel satisfactory to the Trustee, that there is a
     significant risk that the Trust would cause any of the Participating Plans
     to be cease to be unfunded under ERISA prior to actual payment of any
     Benefits. For purposes of this section, "significant risk" shall be based
     on (i) judicial authority or opinion of the U.S. Department of Labor,
     Treasury Department or Internal Revenue Service or (ii) a required
     amendment under ERISA or the Internal Revenue Code, which failure to amend
     could result in significant penalty to the Company.

     If this Trust Agreement is terminated under (A) or (B), the Trust assets
shall be distributed, in accordance with the Company's written direction, as
follows:

     (i) If the Company determines it is possible to create a new trust which
     does not result in a Trust Beneficiary's constructive receipt of Benefits
     under any Participating Plan or which will retain the Participating Plan's
     status as "unfunded" under ERISA, Trust assets shall be transferred to the
     new trust. The terms of the new trust shall be similar in all other
     respects to this Trust.

     (ii) If the Company determines that it is not possible to create a new
     trust, then the assets shall be distributed according to the allocation to
     the Trust Beneficiaries under Section 12.1.

     When all payments which have or may become payable pursuant to the terms of
this Trust have been made or the Trust has been exhausted pursuant to a
termination of this Trust Agreement under (A) or (B) above prior to a Change in
Control, the Trustee shall

                                       27
<PAGE>

pay all remaining assets to the Company upon the Company's certification of
payments, subject to the Trustee's right to reserve such amounts it reasonably
determines to be necessary to pay outstanding and accrued charges against the
Trust.

     Section 28.2. On and after the occurrence of a Change in Control, the
     -------------
Independent Plan Administrator may in its discretion direct the Trustee to
terminate this Trust Agreement and in conjunction therewith the Independent Plan
Administrator shall direct the Trustee as to the names of the Trust
Beneficiaries who are to receive payments and the time, amount and form of
payment of Benefits and any remaining assets of the Trust, subject to the
Trustee's right to reserve such amounts the Trustee determines necessary for
outstanding and accrued charges against the Trust.

                                   SECTION 29

                                   SUCCESSORS

     Any successor in interest to the Trustee shall automatically become Trustee
under this Trust Agreement.

                                   SECTION 30

                                 COMMUNICATIONS

     Any communications (including notices, instructions, or directions)
required or permitted hereunder to be given by the Company shall be given in
writing addressed to the Trustee and signed by an officer of the Company or
other person or persons whom the Company notifies the Trustee are from time to
time authorized to sign such communications, and the Company warrants that all
communications given pursuant to this Section 30 may be relied upon by the
Trustee. The Company shall furnish the Trustee specimen signatures of all
persons authorized to sign communications to the Trustee.

                                   SECTION 31

                             UNCLAIMED DISTRIBUTIONS

     If any benefit payment mailed by regular U.S. Mail to the last address of
the payee furnished by the Company is returned unclaimed, the Trustee shall so
notify the Company and shall discontinue further payments to such payee until it
receives further instructions of the Company.

                           PROHIBITION OF ASSIGNMENTS

     Except insofar as applicable law may otherwise require and subject to
Sections 1, 2, 21.1 and 21.2 of this Trust Agreement, (i) no amount payable to
or in respect of any Trust Beneficiary at any time under the Trust shall be
subject in any manner to direction by anticipation, sale, transfer, assignment,
bankruptcy, pledge, attachment, or charge of any kind, and any attempt to so
alienate, sell, transfer, assign, pledge, attach, change or otherwise encumber
any such amount, whether presently or thereafter payable, shall be void and (ii)
the Trust shall in no manner be liable for or subject to the debts or
liabilities of any Trust Beneficiary. No amount held under this Trust Agreement
shall be subject to voluntary or involuntary alienation.

                                   SECTION 33

                                  GOVERNING LAW

Lyondell Chemical Company

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

STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

As Adopted Effective February 3, 2000
<PAGE>

                            LYONDELL CHEMICAL COMPANY
                  STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

1.   Purpose.
     -------

     The Stock Option Plan for Non-Employee Directors of Lyondell Chemical
     Company (the "Plan") is intended to provide non-employee directors of
     Lyondell Chemical Company (the "Company") with an increased proprietary
     interest in the Company's success and progress by granting them options to
     acquire shares of the Company's Common Stock ("Common Stock") in accordance
     with the terms and conditions set forth below. The Plan is intended to
     increase the alignment of non-employee directors with the Company's
     shareholders.

2.   Administration.
     --------------

     The Plan is to be administered by the Board of Directors of the Company
     (the "Board"). The Directors Benefit Committee shall have all necessary
     authority and discretion to interpret any provision of this Plan or to
     determine any question regarding grants of options under this Plan. Any
     determination or interpretations of the Directors Benefits Committee shall
     be final, conclusive and binding on all persons.

3.   Eligibility.
     -----------

     All current or subsequently elected members of the Board who at the time
     such service began were not, and for the preceding ten years had not been,
     executive officers or employees of the Company or any of its subsidiaries
     ("Eligible Directors") shall be eligible to participate in the Plan.

4.   Grants.
     ------

     The Board shall have full discretion to grant Options to individuals who
     are Eligible Directors at the time the Option is granted. In exercising
     such discretion, the Board shall obtain the advice of the Corporate
     Governance Committee of the Board. The Board may, in its discretion,
     provide for the extension of the exercisability of an Option, accelerate
     the vesting or exercisability of an Option, eliminate or make less
     restrictive any restrictions contained in an Award Agreement, waive any
     restriction or other provision of this Plan or an Award Agreement or
     otherwise amend or modify an Option in any manner that is either (i) not
     adverse to the Eligible Director holding the Option or (ii) consented to by
     such Eligible Director. The grant of options to acquire Common Stock
     awarded to non-employee directors of the Company at the meeting of the
     Board on February 3, 2000 shall be included in this Plan for administration
     purposes.

                                       2
<PAGE>

5.   Terms and Conditions of Options.
     -------------------------------

          (a) Award Agreement. Each Option granted hereunder shall be described
              ---------------
     in an Award Agreement, which shall be subject to the terms and conditions
     of the Plan and shall be signed by the Eligible Director and by the
     appropriate officer for and on behalf of the Company.

          (b) General Terms. Options granted hereunder shall be nonqualified
              -------------
     options within the meaning of Section 83 of the Internal Revenue Code of
     1986, as amended (the "Code"). The Option shall contain such terms and
     conditions as may be approved by the Board. Notwithstanding the foregoing,
     however, the exercise price of an Option shall not be less than the "Fair
     Market Value" (as hereinafter defined) of a share of Common Stock on the
     date of grant of the Option, and shall not be less than the Fair Market
     Value of a share of Common Stock on the date of grant of any outstanding
     Option that is relinquished in connection with the grant of a new Option.
     For purposes of this Plan, the term "Fair Market Value" shall have the
     meaning given such term under the Company's 1999 Long-Term Incentive Plan.

          (c) Termination of Service. Upon the Eligible Director's termination
              ----------------------
     of service as a member of the Board, any unexercised Options shall be
     treated as provided in the specific Award Agreement evidencing the Option.
     Unless otherwise specifically provided in the Award Agreement, each Option
     granted pursuant to this Plan shall immediately terminate to the extent the
     Option is not vested (or does not become vested as a result of such
     termination of service as a member of the Board) on the date the Eligible
     Director terminates service as a member of the Board.

          (d) Disability or Retirement. Notwithstanding the provisions of
              ------------------------
     subsection 5(c), if an Eligible Director ceases to be a member of the Board
     by reason of death, Disability or Retirement, the Options granted to such
     Eligible Director shall become immediately vested and exercisable.

          For purposes of this section, the following definitions apply:

          (i) "Disability" shall mean a permanent and total disability as
          defined in Section 22(e)(3) of the Code.

          (ii) "Retirement" shall mean ceasing to be a director of the Company
          (i) on or after age 72 or (ii) at any time prior to age 72 with the
          consent of a majority of the members of the Board other than the
          Eligible Director.

6.   Stock Option Exercise.
     ---------------------
     The price at which shares of Common Stock may be purchased under an Option
     shall be paid in full at the time of exercise in cash or, if permitted by
     the Board, by means of tendering Common Stock or surrendering Restricted
     Stock awarded under the Restricted Stock Plan for Non-Employee Directors,
     valued at Fair Market Value on the date of

                                       3
<PAGE>

     exercise, or any combination thereof. The Board shall determine acceptable
     methods for tendering Common Stock or Restricted Stock to exercise an
     Option as it deems appropriate. The Board may provide for procedures to
     permit the exercise of an Option by use of the proceeds to be received from
     the sale of Common Stock issuable pursuant to the exercise of the Option.
     Unless otherwise provided in the applicable Award Agreement, in the event
     shares of Restricted Stock are tendered as consideration for the exercise
     of an Option, a number of the shares issued upon the exercise of the
     Option, equal to the number of shares of Restricted Stock used as
     consideration therefor, shall be subject to the same restrictions as the
     Restricted Stock so submitted as well as any additional restrictions that
     may be imposed by the Board.

7.   Shares Available Under the Plan
     -------------------------------

     The Common Stock to be delivered upon exercise of an Option shall be
     limited to treasury shares.

     Any shares of Common Stock that are subject to Options under this plan that
     are terminated, forfeited or surrendered or which expire unexercised will
     again be available for option awards under this Plan.

8.   Adjustments.
     -----------

          (a) The existence of outstanding Options shall not affect in any
     manner the right or power of the Company to make or authorize any or all
     adjustments, recapitalization, reorganizations or other changes in the
     ownership of the Company or its business or any merger or consolidation of
     the Company, or any issue of bonds, debentures, preferred or prior
     preference stock (whether or not such issue is prior to, on a parity with
     or junior to the Common Stock) or other obligations, or the dissolution or
     liquidation of the Company, or any sale or transfer of all or any part of
     its assets or business, or any other Company act or proceeding of any kind,
     whether or not of a character similar to that of the acts or proceedings
     enumerated above.

          (b) In the event of any Common Stock distribution or split,
     recapitalization, extraordinary distribution, merger, consolidation,
     combination or exchange of shares of Common Stock or similar change or upon
     the occurrence of any other event that the Board, in its sole discretion,
     deems appropriate, the (i) the number of shares of Common Stock covered by
     outstanding Options; and (ii) the Exercise Price in respect of such Options
     shall be adjusted as appropriate.

          (c) In the event of a corporate merger, consolidation, acquisition of
     property or stock, separation, reorganization or liquidation (such event
     hereinafter referred to as a "Transaction"), the Board shall be authorized
     (i) to issue or assume Options by means of substitution of new Options, as
     appropriate, for previously issued Options or to assume previously issued
     Options as part of such adjustment, (ii) to make provision, prior to the
     Transaction, for the acceleration of the vesting and exercisability of, or
     lapse of restrictions with respect to, Options or (iii) in the event of a
     Transaction of which the Company is not

                                       4
<PAGE>

     the surviving corporation, to (A) cancel Options and give the Eligible
     Director an opportunity to exercise for 30 days prior to such cancellation
     or (B) settle an Option by a cash payment equal to the difference between
     the Fair Market Value per share of Common Stock on the date of the
     Transaction and the exercise price of the Option, multiplied by the number
     of shares subject to the Option.

9.   Assignability.
     -------------

     Except as otherwise provided herein, no Option granted under this Plan
     shall be sold, transferred, pledged, assigned or otherwise alienated or
     hypothecated by an Eligible Director other than by will or the laws of
     descent and distribution, and during the lifetime of an Eligible Director,
     any Option shall be exercisable only by him, or, in the case of an Eligible
     Director who is mentally incapacitated, the Option shall be exercisable by
     his guardian or legal representative. The Board may prescribe and include
     in applicable Award Agreements other restrictions on transfer. Any
     attempted assignment or transfer in violation of this Section shall be null
     and void. Upon the Eligible Director's death, the personal representative
     or other person entitled to succeed to the rights of the Eligible Director
     (the "Successor Optionee") may exercise such rights. A Successor Optionee
     must furnish proof satisfactory to the Company of his or her right to
     exercise the Option under the Eligible Director's will or under the
     applicable laws of descent and distribution.

     Subject to approval by the Board in its sole discretion, all or a portion
     of the Option granted to an Eligible Director under the Plan may be
     transferable by the Eligible Director, to the extent and only to the extent
     specified in such approval, to (i) the children or grandchildren of the
     Eligible Director ("Immediate Family Members"), (ii) a trust or trusts for
     the exclusive benefit of such Immediate Family Members ("Immediate Family
     Member Trusts"), or (iii) a partnership or partnerships in which such
     Immediate Family Members have at least ninety-nine percent (99%) of the
     equity, profit and loss interests ("Immediate Family Member Partnerships");
     provided that the Award Agreement pursuant to which such Awards are granted
     (or an amendment thereto) must expressly provide for transferability in a
     manner consistent with this Section. Subsequent transfers of transferred
     Awards shall be prohibited except by will or the laws of descent and
     distribution, unless such transfers are made to the original Eligible
     Director or a person to whom the original Eligible Director could have made
     a transfer in the manner described herein. No transfer shall be effective
     unless and until written notice of such transfer is provided to the Board,
     in the form and manner prescribed by the Board. Following transfer, any
     such Options shall continue to be subject to the same terms and conditions
     as were applicable immediately prior to transfer, and, except as otherwise
     provided herein, the term "Eligible Director" shall be deemed to refer to
     the transferee. The consequences of termination of service as a director
     shall continue to be applied with respect to the original Eligible
     Director, following which the Options shall be exercisable by the
     transferee only to the extent and for the periods specified in this Plan
     and the Award Agreement.

10.  Termination or Amendment of the Plan.
     ------------------------------------

     The Board may at any time terminate the Plan and may from time to time
     alter or amend the

                                       5
<PAGE>

     Plan or any part hereof (including any amendment deemed necessary to ensure
     that the Company may comply with any regulatory requirement) without
     shareholder approval, unless otherwise required by law or by the rules of
     the Securities and Exchange Commission or New York Stock Exchange. No
     termination or amendment of the Plan may, without the consent of an
     Eligible Director, impair the rights of such director with respect to
     Options previously granted under the Plan.

11.  Miscellaneous.
     -------------

     (a)  Nothing in the Plan shall be deemed to create any obligation on the
          part of the Board to nominate any director for re-election by the
          Company's shareholders.

     (b)  The Company shall have the right to require, prior to the issuance or
          delivery of any Common Stock upon exercise of an Option, payment by an
          Eligible Director of any taxes required by law with respect to the
          issuance or delivery of such shares.

12.  Governing Law.
     -------------

     The Plan shall be construed according to the law of the State of Texas to
     the extent federal law does not supersede and preempt state law.

13.  Effective Date.
     --------------

     The Plan was originally effective as of February 1, 2000.
