Committee may at any time during a Plan Year on 60 days' notice to a Participant

                  4.1 ESTABLISHING A PARTICIPANT'S ACCOUNT. The Committee shall
establish an Account for each Participant in a special Foreign Deferred

time.

                  4.2 BASIC BENEFIT ACCOUNT. The Basic Benefit shall be credited

<PAGE>   9

                  4.3 GAUGE FOR DETERMINING BENEFITS. The Basic Benefit credits
described in Section 4.2 shall be credited in non-monetary units equal to the
number of whole shares of Common Stock that could have been purchased at a price
equal to the average closing sale price of a share of Common Stock during the
calendar month for which the allocation is made as reported by the principal
national securities exchange on which the Common Stock is then listed, if the
Common Stock is listed on a national securities exchange, or the average of the
bid and asked price of a share of Common Stock during such month as reported in
the National Association of Securities Dealers Automated Quotation National
Market System (or successor system) listing if the Common Stock is not then
listed on a national securities exchange, provided that if no such closing price
or quotes are so reported during that month or if, in the discretion of the
Committee, another means of determining the fair market value of the Common
Stock for such month shall be necessary and advisable, the Committee may provide
for another means of determining such value, and in monetary units for any
amount that is less than the value of a whole share. Any monetary unit credited
to an Account will be added to the next such amount credited to the Account and
converted into a non-monetary unit as quickly as possible. The value of each
unit credited to an Account and therefore the ultimate value of the deferred
compensation payable to each Participant will increase or decrease in proportion
to the change in the value of a share of Common Stock between the date of the
initial crediting of a unit and the date that the unit is valued for
distribution under Article VI of the Plan.

                                    ARTICLE V

                                     VESTING

                  Upon his Retirement, death or Disability while employed with
the Company, a Participant will have a 100 percent nonforfeitable interest in
the Basic Benefit credited to his Account together with any increase in the
accruals as a result of the rise in the value of the non-monetary units after
they have been initially credited, except for the events of forfeiture described
in Section 6.5. In addition, a Participant's interest in the Basic Benefit
credited to his Account together with any increase in the accruals as a result
of the rise in the value of the non-monetary units after they have been
initially credited shall vest at the rate set out in the vesting schedule below,
except for events of forfeiture described in Section 6.5 and upon termination of
the Plan as provided in Section 9.3.

                                  DISTRIBUTIONS

                  6.1 DEATH. Upon the death of a Participant, his Beneficiary or
Beneficiaries shall receive the value of the amounts credited to the
Participant's Accounts in the Foreign Deferred Compensation Ledger determined
under Section 6.7, and in the discretion of the Committee, the distribution
shall be made in shares of Common Stock or in one lump sum payment in cash, or
in a combination of shares of Common Stock and cash, or in a combination of
shares of Common Stock and cash. The distribution shall be made within 90 days
after the Participant's death. Unless otherwise provided by the Committee, all
Distributions shall be made in shares of Common Stock.

                  Each Participant, upon notification of his participation in
the Plan, shall file with the Committee a designation of a Beneficiary or
Beneficiaries to whom distributions otherwise due the Participant shall be made
in the event of his death prior to the distribution of the amount credited to
his Accounts in the Foreign Deferred Compensation Ledger. The designation will
be effective upon receipt by the Committee of a properly executed form which the
Committee has approved for that purpose. The Participant may from time to time
revoke or change any designation of Beneficiary by filing another approved
Beneficiary designation form with the Committee. If there is no valid
designation of Beneficiary on file with the Committee at the time of the
Participant's death, or if all of the Beneficiaries designated in the last
Beneficiary designation have predeceased the Participant or otherwise ceased to
exist, the Beneficiary will be the Participant's spouse, if the spouse survives
the Participant, or otherwise the Participant's estate.

                  6.2 DISABILITY. Upon the Disability of a Participant, the
Participant shall receive the value of the amounts credited to the Participant's
Accounts in the Foreign Deferred Compensation Ledger determined under Section
6.7, and in the discretion of the Committee, the distribution shall be made in
shares of Common Stock or in one lump sum payment in cash, or in a combination
of shares of Common Stock and cash.. The distribution shall be made within 90
days after the Participant becomes disabled.

                  6.3 RETIREMENT. Upon the Retirement of a Participant on or
after attaining age 60, the Participant shall receive the value of the amounts
credited to his Accounts in the Foreign Deferred Compensation Ledger determined
under Section 6.7, and at the discretion of the

                                       5
<PAGE>   11

Committee, the distribution shall be made in shares of Common Stock or in one
lump sum payment in cash, or in a combination of shares of Common Stock and
cash. The distribution shall be made within 90 days after the Participant's
Retirement.

                  6.4 TERMINATION PRIOR TO DEATH, DISABILITY OR RETIREMENT. Upon
a Participant's termination from the employ of all Companies prior to death,
Disability or Retirement, the Participant shall receive the portion of the
amount credited to his Accounts in the Foreign Deferred Compensation Ledger,
determined under Section 6.7, which is vested under Article V, and at the
discretion of the Committee, the distribution shall be made in Common Stock or
in one lump sum payment in cash, or in a combination of shares of Common Stock
and cash. Distribution shall be made within 90 days after the Participant's
termination. Any amounts not then vested shall be forfeited.

                  6.5 FORFEITURE FOR CAUSE. If the Committee finds, after full
consideration of the facts presented on behalf of both the Company and a former
Participant, that the Participant was discharged by the Company for fraud,
embezzlement, theft, commission of a felony, proven dishonesty in the course of
his employment by the Company which damaged the Company, or for disclosing trade
secrets of the Company, the entire amount credited to his Accounts in the
Foreign Deferred Compensation Ledger shall be forfeited even though it may have
been previously vested under Article V. The decision of the Committee as to the
cause of a former Participant's discharge and the damage done to the Company
shall be final. No decision of the Committee shall affect the finality of the
discharge of the Participant by the Company in any manner.

                  6.6 RESPONSIBILITY FOR DISTRIBUTIONS AND WITHHOLDING OF TAXES.
The Committee shall furnish information to the Company last employing the
Participant concerning the amount and form of distribution to any Participant
entitled to a distribution so that the Company may make the distribution
required. It will also calculate the deductions, if any, from the amount of the
benefit paid under the Plan for any taxes required to be withheld by any
government or similar authority and will cause them to be withheld and paid to
the appropriate authority. If a Participant earns deferred compensation under
the Plan while in the service of more than one Company, each Company for which
the Participant worked shall pay the amount attributable to the period the
Participant was in the service of that Company.

                  6.7 DISTRIBUTION DETERMINATION DATE. For purposes of all
distributions described in this Article VI, the determination date for valuing
the amounts credited to a Participant's Accounts shall be the day which triggers
the beginning of the 90-day period described in Section 6.1, 6.2, 6.3, or 6.4,
as applicable. For purposes of all distributions in shares of Common Stock
described in this Article VI, the determination date shall be the date of the
actual direction by the Company in writing to the transfer agent to issue a
certificate for the Common Stock to the Participant or his Beneficiary, and the
number of shares issued shall be equal to the vested non-monetary units credited
to the Participant's Accounts.

                  6.8 VALUATION OF ACCOUNTS FOR CASH DISTRIBUTIONS. For purposes
of all distributions in cash described in this Article VI, the Committee shall
determine the fair market value of the non-monetary units of Common Stock deemed
credited to a Participant's Account as of the

                                       6
<PAGE>   12

determination date specified in Section 6.7. For this purpose, the fair market
value of a share of Common Stock shall be the average closing price of a share
of Common Stock during the month in which the determination date described in
Section 6.7 occurs, as reported by the principal national securities exchange on
which the Common Stock is then listed if it is listed on a national securities
exchange or the average of the bid and asked price of a share of Common Stock
during such month as reported in the National Association of Securities Dealers
Automated Quotation National Market System (or successor system) listing if the
Common Stock is not then listed on a national securities exchange, provided that
if no such closing price or quotes are so reported during that month or if, in
the discretion of the Committee, another means of determining the fair market
value of the Common Stock for such month shall be necessary and advisable, the
Committee may provide for another means of determining such value.

majority of the members of the Committee shall constitute a quorum for the
transaction of business and the vote of a majority of the members present at any

Committee may decide any question by a vote, taken without a meeting, of a
majority of its members. A member of the Committee who is also a Participant

                  7.3 POWERS OF THE COMMITTEE. The Committee shall have the
exclusive responsibility for the general administration of the Plan according to

<PAGE>   13

                  (c) to correct any defect, supply any omission or reconcile
         any inconsistency that may appear in the Plan in the manner and to the
         extent it deems expedient to carry the Plan into effect;

                  (d) to designate the persons eligible to become Participants;

                  (e) to determine all controversies relating to the
         administration of the Plan, including but not limited to:

                           (1) differences of opinion arising between the
                  Company and a Participant; and

                           (2) any question it deems advisable to determine in
                  order to promote the uniform administration of the Plan for
                  the benefit of all parties at interest; and

                  (f) to delegate by written notice those clerical and
         recordation duties of the Committee, as it deems necessary or advisable
         for the proper and efficient administration of the Plan.

                  7.4 COMMITTEE DISCRETION. The Committee in exercising any
power or authority granted under the Plan or in making any determination under
the Plan shall perform or refrain from performing those acts using its sole
discretion and judgment. Any decision made by the Committee or any refraining to
act or any act taken by the Committee in good faith shall be final and binding
on all parties and shall not be subject to de novo review.

                  7.5 ANNUAL STATEMENTS. The Committee shall cause each
Participant to receive an annual statement as soon as administratively feasible
after the conclusion of each Plan Year containing a statement of the
Participant's Accounts in the Foreign Deferred Compensation Ledger through the
end of that Plan Year. The statement shall include a report of the Basic Benefit
and the number of units credited to each Participant's Account for that Plan
Year.

                  7.6 REIMBURSEMENT OF EXPENSES. The Committee shall serve
without compensation for their services but shall be reimbursed by GP for all
expenses properly and actually incurred in the performance of its duties under
the Plan.

                                  ARTICLE VIII

                            ADOPTION BY SUBSIDIARIES

                  8.1 PROCEDURE FOR AND STATUS AFTER ADOPTION. Any Subsidiary
may, with the approval of the Committee, adopt the Plan by appropriate action of
its board of directors. The terms of the Plan will apply separately to each
Subsidiary adopting the Plan and its Participants in the same manner as is
expressly provided for GP and its Participants except that the powers of the
Board of

                                       8
<PAGE>   14

Directors and the Committee under the Plan shall be exercised by the Board of
Directors of GP alone. GP and each Subsidiary that adopts the Plan shall bear
the cost of providing plan benefits for its own Participants. It is intended
that the obligation of GP and each Subsidiary with respect to its Participants
shall be the sole obligation of the company that is employing the Participant
and shall not bind any other company.

                  8.2 TERMINATION OF PARTICIPATION BY ADOPTING SUBSIDIARY. Any
Subsidiary that adopts the Plan may, by appropriate action of its board of
directors, terminate its participation in the Plan. The Committee may, in its
discretion, also terminate a Subsidiary's participation in the Plan at any time.
The termination of the participation in the Plan by a Subsidiary shall not,
however, affect the rights of any Participant who is working or has worked for
the Subsidiary as to amounts and/or units previously standing to his credit in
his Accounts in the Foreign Deferred Compensation Ledger.

                                   ARTICLE IX

                          AMENDMENT AND/OR TERMINATION

                  9.1 AMENDMENT OR TERMINATION OF THE PLAN. The Board of
Directors may amend or terminate the Plan at any time by an instrument in
writing without the consent of any adopting Company or any Participant.

                  9.2 NO RETROACTIVE EFFECT ON AWARDED BENEFITS. No amendment
shall affect the rights of any Participant to the amounts and/or units then
standing to his credit in his Accounts in the Foreign Deferred Compensation
Ledger. However, the Board of Directors shall retain the right to change at any
time and in any manner the method of calculating all Basic Benefits to be
accrued in the future, and the gauge to be used to determine future increases or
decreases in amounts accrued after the date of the amendment.

                  9.3 EFFECT OF TERMINATION. If the Plan is terminated, all
amounts of Basic Benefits accrued by the Company and credited to a Participant's
Accounts shall immediately vest as if the Participant were entitled to and did
retire on the date the Plan terminated. Distribution would then commence in
accordance with Section 6.3. However, the forfeiture provisions of Section 6.5
would continue to apply until the actual date of distribution.

                                    ARTICLE X

                                     PAYMENT

                  10.1 PAYMENTS UNDER THIS AGREEMENT ARE THE OBLIGATION OF THE
COMPANY. The Company shall be liable for all benefits due the Participants under
the Plan.

                                       9
<PAGE>   15

                  10.2 PARTICIPANTS MUST RELY ONLY ON GENERAL CREDIT OF THE
COMPANY. The Plan is only a general corporate commitment and each Participant
must rely upon the general credit of the Company for the fulfillment of its
obligations under the Plan. Under all circumstances the rights of Participants
to any asset held by the Company shall be no greater than the rights expressed
in this agreement. Nothing contained in the Plan shall constitute a guarantee by
the Company that the assets of the Company will be sufficient to pay any
benefits under the Plan or would place the Participant in a secured position
ahead of general creditors and judgment creditors of the Company.

                                   ARTICLE XI

                                  MISCELLANEOUS

                  11.1 LIMITATION OF RIGHTS. Nothing in the Plan will be
construed:

                  (a) to give any employee of any Company any right to be
         designated a Participant in the Plan;

                  (b) to give a Participant any right with respect to the Basic
         Benefit accrued except in accordance with the terms of the Plan;

                  (c) to limit in any way the right of the Company to terminate
         a Participant's employment with the Company at any time;

                  (d) to evidence any agreement or understanding, expressed or
         implied, that the Company will employ a Participant in any particular
         position or for any particular remuneration; or

                  (e) to give a Participant or any other person claiming through
         him any interest or right under the Plan other than that of any
         unsecured general creditor of the Company.

                  11.2 DISTRIBUTION TO MINOR OR INCAPACITATED PERSON. If the
Committee determines that any person to whom a payment is due is a minor or
unable to care for his affairs because of physical or mental disability, it
shall have the authority to cause his payments under the Plan to be made to his
parent, legal guardian, spouse, brother, sister or other person whom the
Committee determines. The Committee shall not be responsible to oversee the
application of those payments. Payments made pursuant to this power shall be a
complete discharge of all liability under the Plan and the obligations of the
Company and the Committee.

                  11.3 NONALIENATION OF BENEFITS. No right or benefit provided
in the Plan shall be transferable by the Participant except, upon his death, to
a named Beneficiary as provided in the Plan. No right or benefit under the Plan
shall be subject to anticipation, alienation, sale, assignment, pledge,
encumbrance or charge, and any attempt to anticipate, alienate, sell, assign,
pledge, encumber, or charge the same shall be void. No right or benefit under
the Plan shall in any manner

                                       10
<PAGE>   16

be liable for or subject to any debts, contracts, liabilities or torts of the
person entitled to such benefits. If any Participant or any Beneficiary becomes
bankrupt or attempts to anticipate, alienate, sell, assign, pledge, encumber or
charge any right or benefit under the Plan, that right or benefit shall, in the
discretion of the Committee, cease. In that event, the Committee may have the
Company hold or apply the right or benefit or any part of it to the benefit of
the Participant or Beneficiary, his or her spouse, children or other dependents
or any of them in any manner and in any proportion the Committee believes to be
proper in its sole and absolute discretion, but is not required to do so.

                  11.4 RELIANCE UPON INFORMATION. The Committee shall not be
liable for any decision or action taken in good faith in connection with the
administration of the Plan. Without limiting the generality of the foregoing,
any decision or action taken by the Committee when it relies upon information
supplied it by any officer of the Company, the Company's legal counsel, the
Company's independent accountants or other advisors in connection with the
administration of the Plan shall be deemed to have been taken in good faith.

                  11.5 SEVERABILITY. If any term, provision, covenant or
condition of the Plan is held to be invalid, void or otherwise unenforceable,
the rest of the Plan shall remain in full force and effect and shall in no way
be affected, impaired or invalidated.

                  11.6 NOTICE. Any notice or filing required or permitted to be
given to the Committee or a Participant shall be sufficient if in writing and
hand delivered or sent by mail (postage prepaid) to the principal office of the
Company or to the residential mailing address of the Participant. Notice shall
be deemed to be given as of the date of hand delivery or if delivery is by mail,
as of the date shown on the postmark.

                  11.7 GENDER AND NUMBER. If the context requires it, words of
one gender when used in the Plan will include the other genders, and words used
in the singular or plural will include the other.

                  11.8 GOVERNING LAW. The Plan will be construed, administered
and governed in all respects by the laws of the State of Texas, United States of
America.

                  11.9 EFFECTIVE DATE. The Plan will be operative and effective
on the effective date of the distribution by Weatherford International, Inc. to
its stockholders of all the outstanding shares of stock of GP.

                      EXECUTIVE DEFERRED COMPENSATION PLAN

         WHEREAS, Grant Prideco, Inc. desires to adopt a deferred compensation
plan for a select group of management and highly compensated employees;

         WHEREAS, as a result of the distribution by Weatherford International,
Inc. to its stockholders of all of the outstanding shares of stock of Grant
Prideco, Inc. (the "Spin-Off"), Grant Prideco, Inc. shall no longer be a
subsidiary of Weatherford International, Inc. as of the effective date of the
Spin-Off;

                         DEFERRALS AND BENEFIT ACCRUALS

         3.1 BASIC BENEFIT ACCRUAL. Subject to Section 3.4, the Company shall
accrue an amount for the benefit of each Participant equal to 7 1/2 percent of
the Participant's Compensation for the Plan Year.

         3.2 DEFERRAL ELECTION. A Participant may elect, within 30 days of
notification that he is eligible to participate in the Plan, and not less than
six months prior to the effective date of the first deferral, and thereafter not
later than June 30 preceding the next Plan Year, the percentage, if any, of his
Compensation to be earned during the ensuing Plan Year, that is to be deferred
under the Plan. A Participant may defer a minimum of one percent but not more
than 7 1/2 percent of his Compensation for the Plan Year. Prior to the election
period the Committee shall notify all eligible Participants of their right to
make a deferral election. Once an election has been made as to the percentage to
be deferred, it becomes irrevocable for the Plan Year. The election to defer a
percentage of Compensation shall be effective only upon the timely receipt by
the Committee of the Participant's percentage deferral election on such form as
will be determined by the Committee from time to time. Except with respect to
the election by a newly eligible Participant as described above, if the
Committee fails to receive a properly filed election form on or prior to June 30
of the year immediately preceding the Plan Year to which the election applies,
revoking or modifying a prior election, the prior election shall remain in
effect. If a timely election form is not received, the Participant shall be
deemed to have elected not to defer any part of his Compensation

                                      III-1

<PAGE>   12

for that Plan Year. An election to defer for one Plan Year shall remain
effective for subsequent Plan Years until modified or revoked in accordance with
this Section 3.2.

         3.3 COMPANY MATCH ACCRUAL. Subject to Section 3.4, each Plan Year the
Company shall credit the Company Match Account of each Participant who elects to
defer a portion of his Compensation under the Plan with an amount equal to 100
percent of the amount that he defers for the Plan Year.

         3.4 REDUCTION OF ACCRUALS. The Committee may reduce the percentage of
the Basic Benefit accrual and/or the Company Match accrual upon written notice
to a Participant. Such reduction shall apply only as to Plan Years following
such notice, or in the case of a new Participant, beginning on the date that the
Participant first receives credit under Section 3.1, 3.2 or 3.3.

                                      III-2

                                   ARTICLE IV

                                     ACCOUNT

         4.1 ESTABLISHING A PARTICIPANT'S ACCOUNT. The Committee shall establish
an Account for each Participant in a special Deferred Compensation Ledger which
shall be maintained by the Company. The Account shall reflect the amount of the
Company's obligation to the Participant at any given time.

         4.2 Basic Benefit Account. The Basic Benefit shall be credited to each
Participant's Basic Benefit Account as of the last day of each month of each
Plan Year for the accrual attributable to Compensation paid during that month.

         4.3 Deferral Account. The amount deferred by a Participant, if any,
shall be credited to each Participant's Deferral Account as of the last day of
each month in which the Participant would have received the amount deferred but
for his election to defer.

         4.4 Company Match Account. The Company Match shall be credited to each
Participant's Company Match Account coincident with the crediting of the
Participant's Deferral to the Participant's Deferral Account.

         4.5 Gauge for Determining Benefits. The Basic Benefit, Deferral and
Company Match credits described in Sections 4.2, 4.3 and 4.4 shall be deemed to
be credited in non-monetary units equal to the number of whole shares of Common
Stock that could have been purchased at a price equal to the average closing
sale price of a share of Common Stock during the calendar month for which the
allocation is made as reported by the principal national securities exchange on
which the Common Stock is then listed if the Common Stock is listed on a
national securities exchange or the average of the bid and asked price of a
share of Common Stock during such month as reported

                                      IV-1

<PAGE>   14

in the National Association of Securities Dealers Automated Quotation National
Market System (or successor system) listing if the Common Stock is not then
listed on a national securities exchange, provided that if no such closing price
or quotes are so reported during that month or if, in the discretion of the
Committee, another means of determining the fair market value of the Common
Stock for such month shall be necessary and advisable, the Committee may provide
for another means of determining such value, and in monetary units for any
amount that is less than the value of a whole share. Any monetary unit credited
to an Account will be added to the next such amount credited to the Account and
converted into a non-monetary unit as quickly as possible. The value of each
unit credited to an Account, and therefore the ultimate value of the deferred
compensation payable to each Participant, will increase or decrease in
proportion to the change in the value of a share of Common Stock between the
date of the initial crediting of a unit and the date that the unit is valued for
distribution under Article VI of the Plan.

         5.1 DEFERRALS. A Participant shall have a 100 percent nonforfeitable
interest in his Deferrals under the Plan at all times. A Participant will also
have a 100 percent nonforfeitable interest in any increase in the Deferral as a
result of the rise in the value of the non-monetary units after his Deferral has
been initially credited.

         5.2 BASIC BENEFIT AND COMPANY MATCH. Upon his Retirement, death or
Disability while employed with the Company, a Participant will have a 100
percent nonforfeitable interest in the Basic Benefit and Company Match credited
to his Account together with any increase in the accruals as a result of the
rise in the value of the non-monetary units after they have been initially
credited, except for the events of forfeiture described in Section 6.5. In
addition, a Participant's interest in the Basic Benefit and Company Match
credited to his Account together with any increase in the accruals as a result
of the rise in the value of the non-monetary units after they have been
initially credited shall vest at the rate set out in the vesting schedule below,
except for events of forfeiture described in Section 6.5 and upon termination of
the Plan as provided in Section 9.3.

         6.1 DEATH. Upon the death of a Participant, his Beneficiary or
Beneficiaries shall receive the value of the amounts credited to the
Participant's Accounts in the Deferred Compensation Ledger determined under
Section 6.7, and in the discretion of the Committee, the distribution shall be
made in shares of Common Stock or in one lump sum payment in cash, or in a
combination of shares of Common Stock and cash. The distribution shall be made
within 30 days after the Participant's death.

         Each Participant, upon notification of his participation in the Plan,
shall file with the Committee a designation of a Beneficiary or Beneficiaries to
whom distributions otherwise due the Participant shall be made in the event of
his death prior to the distribution of the amount credited to his Accounts in
the Deferred Compensation Ledger. The designation will be effective upon receipt
by the Committee of a properly executed form which the Committee has approved
for that purpose. The Participant may from time to time revoke or change any
designation of Beneficiary by filing another approved Beneficiary designation
form with the Committee. If there is no valid designation of Beneficiary on file
with the Committee at the time of the Participant's death, or if all of the
Beneficiaries designated in the last Beneficiary designation have predeceased
the Participant or otherwise ceased to exist, the Beneficiary will be the
Participant's spouse, if the spouse survives the Participant, or otherwise the
Participant's estate. Any Beneficiary designation which designates any person or
entity other than the Participant's spouse must be consented to in writing by
the spouse in a form acceptable to the Committee in order to be effective.

         6.2 DISABILITY. Upon the Disability of a Participant, the Participant
shall receive the value of the amounts credited to the Participant's Accounts in
the Deferred Compensation Ledger determined under Section 6.7, and at the
discretion of the Committee, the distribution shall be made in shares of Common

made in Common Stock or in one lump sum payment in cash, or in a combination of
shares of Common Stock and cash. The distribution shall be made within 30 days
after the Participant's Retirement.

         6.4 TERMINATION PRIOR TO DEATH, DISABILITY OR RETIREMENT. Upon a

discretion of the Committee, the distribution shall be made in shares of Common
Stock or in one lump sum payment in cash, or in a combination of shares of

         6.5 FORFEITURE FOR CAUSE. If the Committee finds, after full
consideration of the facts presented on behalf of both the Company and a former
Participant, that the Participant was discharged by the Company for fraud,
embezzlement, theft, commission of a felony, proven dishonesty in the course of
his employment by the Company which damaged the Company, or for disclosing trade
secrets of the Company, the entire amount credited to his Basic Benefit Account
and Company Match Account in the Deferred Compensation Ledger shall be forfeited
even though it may have been previously vested under Section 5.2. The decision
of the Committee as to the cause of a former Participant's discharge and the
damage done to the Company shall be final. No decision of the Committee shall
affect the finality of the discharge of the Participant by the Company in any
manner.

         6.6 RESPONSIBILITY FOR DISTRIBUTIONS AND WITHHOLDING OF TAXES. The
Committee shall furnish information to the Company employing the Participant
concerning the amount and form of distribution to any Participant entitled to a
distribution so that the Company may make or cause the rabbi trust to make the
distribution required. It will also calculate the deductions from the amount of
the benefit paid under the Plan for any taxes required to be withheld by
federal, state or local government and will cause them to be withheld and paid
to the appropriate authority. If a Participant has deferred compensation under
the Plan while in the service of more than one Company, each Company for which
the Participant worked shall pay the amount attributable to the period the
Participant was in the service of that Company, except to the extent the Company
paid an amount to the Trust which was paid the Participant.

         6.7 DISTRIBUTION DETERMINATION DATE. For purposes of all distributions
described in this Article VI, the determination date for valuing the amounts
credited to a Participant's Accounts shall be the day which triggers the

                                      VI-3

or 6.4, as applicable. For purposes of all distributions in Common Stock and
Grant Stock described in this Article VI, the determination date shall be the

non-monetary units allocated to the Participant's Accounts.

         6.8 VALUATION OF ACCOUNTS FOR CASH DISTRIBUTIONS. For purposes of all
distributions in cash described in this Article VI, the Committee shall
determine the fair market value of the non-monetary units of Common Stock deemed
credited to a Participant's Account as of the determination date specified in
Section 6.7. For this purpose, the fair market value of a share of Common Stock
shall be the average closing price of a share of Common Stock during the month
in which the determination date described in Section 6.7 occurs, as reported by
the principal national securities exchange on which the Common Stock is then
listed if it is listed on a national securities exchange or the average of the
bid and asked price of a share of Common Stock during such month as reported in
the National Association of Securities Dealers Automated Quotation National
Market System (or successor system) listing if the Common Stock is not then
listed on a national securities exchange, provided that if no such closing price
or quotes are so reported during that month or if, in the discretion of the
Committee, another means of determining the fair market value of the Common
Stock for such month shall be necessary and advisable, the Committee may provide
for another means of determining such value.

that adopts the Plan may, by appropriate action of its board of directors,
terminate its participation in the Plan. The Committee may, in its discretion,
also terminate a Subsidiary's participation in the Plan at any time. The
termination of the participation in the Plan by a Subsidiary shall not, however,
affect the rights of any Participant who is working or has worked for the
Subsidiary as to amounts and/or units previously standing to his credit in his
Accounts in the Deferred Compensation Ledger.

                          AMENDMENT AND/OR TERMINATION

         9.1 AMENDMENT OR TERMINATION OF THE PLAN. The Board of Directors may
amend or terminate the Plan at any time by an instrument in writing without the
consent of any adopting Company or any Participant.

         9.2 NO RETROACTIVE EFFECT ON AWARDED BENEFITS. No amendment shall
affect the rights of any Participant to the amounts and/or units then standing
to his credit in his Accounts in the Deferred Compensation Ledger. However, the
Board of Directors shall retain the right to change at any time and in any
manner the method of calculating all Basic Benefits to be accrued in the future,
all amounts deferred by a Participant and all amounts matched by the Company and
the gauge to be used to determine future increases or decreases in amounts
accrued or deferred after the date of the amendment.

         9.3 EFFECT OF TERMINATION. If the Plan is terminated, all amounts of
Basic Benefits accrued by the Company, deferred by Participants and matched by
the Company and credited to a Participant's Accounts shall immediately vest as
if the Participant were entitled to and did retire on the date the Plan
terminated. Distributions would then commence in accordance with Section 6.3.
However, the forfeiture provisions of Section 6.5 would continue to apply until
the actual date of distribution.

                                     PAYMENT

         10.1 PAYMENTS UNDER THIS AGREEMENT ARE THE OBLIGATION OF THE COMPANY.
The Company shall be liable for all benefits due the Participants under the
Plan.

         10.2 PAYMENTS MAY BE MADE TO A RABBI TRUST. Under all circumstances,
the rights of the Participants to the assets held in any rabbi trust created
with respect to the Plan shall be no greater than the rights expressed in this
agreement. Nothing contained in the trust agreement which creates any such rabbi
trust shall constitute a guarantee by any Company that the amounts transferred
by it to the trust shall be sufficient to pay any benefits under the Plan or
would place the Participant in a secured position ahead of judgment and/or
general creditors should the Company become insolvent or bankrupt. Any trust
agreement established with respect to a Plan must specifically set out these
principles so it is clear in the trust agreement that the Participants are only
unsecured general creditors of the Company with respect to their benefits under
the Plan.

         10.3 PARTICIPANTS MUST RELY ONLY ON GENERAL CREDIT OF THE COMPANY. The
Plan is only a general corporate commitment and each Participant must rely upon
the general credit of the Company for the fulfillment of its obligations under
the Plan. Under all circumstances the rights of Participants to any asset held
by the Company shall be no greater than the rights expressed in this agreement.
Nothing contained in this agreement shall constitute a guarantee by the Company
that the assets of the Company will be sufficient to pay any benefits under the
Plan or would place the Participant in a secured position ahead of general
creditors and judgment creditors of the Company. Though the Company may
establish or become a signatory to a rabbi trust to accumulate assets to help
fulfill its obligations, the Plan and any trust created, shall not create any
lien, claim, encumbrance, right, title or other interest of any kind in any
Participant in any asset held by the

                                      X-1

Company, contributed to any trust created, or otherwise be designated to be used
for payment of any of its obligations created in this agreement. No specific
assets of the Company have been or will be set aside, or will be transferred to
a trust or will be pledged for the performance of the Company's obligations
under the Plan which would remove those assets from being subject to the general
creditors and judgment creditors of the Company.

         10.4 PLAN UNFUNDED. It is intended that the Plan shall be unfunded for
tax purposes and for purposes of Title I of ERISA.

                                   ARTICLE XI

                                  MISCELLANEOUS

         11.1 LIMITATION OF RIGHTS. Nothing in the Plan will be construed:

         (a) to give any employee of any Company any right to be designated a
     Participant in the Plan;

         (b) to give a Participant any right with respect to the Basic Benefit
     accrued, the Deferral, or the Company Match accrued except in accordance
     with the terms of the Plan;

         (c) to limit in any way the right of the Company to terminate a
     Participant's employment with the Company at any time;

         (d) to evidence any agreement or understanding, expressed or implied,
     that the Company will employ a Participant in any particular position or
     for any particular remuneration; or

         (e) to give a Participant or any other person claiming through him any
     interest or right under the Plan other than that of any unsecured general
     creditor of the Company.

         11.2 DISTRIBUTION TO MINOR OR INCAPACITATED PERSON. If the Committee
determines that any person to whom a payment is due is a minor or unable to care
for his affairs because of physical or mental disability, it shall have the
authority to cause his payments under the Plan to be made to his parent, legal
guardian, spouse, brother, sister or other person whom the Committee determines.
The Committee shall not be responsible to oversee the application of those
payments. Payments made pursuant to this power shall be a complete discharge of
all liability under the Plan and the obligations of the Company and the
Committee.

         11.3 NONALIENATION OF BENEFITS. No right or benefit provided in the
Plan shall be transferable by the Participant except, upon his death, to a named
Beneficiary as provided in the Plan. No right or benefit under the Plan shall be
subject to anticipation, alienation, sale, assignment,

                                      XI-1

<PAGE>   28

pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell,
assign, pledge, encumber, or charge the same shall be void. No right or benefit
under the Plan shall in any manner be liable for or subject to any debts,
contracts, liabilities or torts of the person entitled to such benefits. If any
Participant or any Beneficiary becomes bankrupt or attempts to anticipate,
alienate, sell, assign, pledge, encumber or charge any right or benefit under
the Plan, that right or benefit shall, in the discretion of the Committee,
cease. In that event, the Committee may have the Company hold or apply the right
or benefit or any part of it to the benefit of the Participant or Beneficiary,
his or her spouse, children or other dependents or any of them in any manner and
in any proportion the Committee believes to be proper in its sole and absolute
discretion, but is not required to do so.

         11.4 RELIANCE UPON INFORMATION. The Committee shall not be liable for
any decision or action taken in good faith in connection with the administration
of the Plan. Without limiting the generality of the foregoing, any decision or
action taken by the Committee when it relies upon information supplied it by any
officer of the Company, the Company's legal counsel, the Company's independent
accountants or other advisors in connection with the administration of the Plan
shall be deemed to have been taken in good faith.

         11.5 SEVERABILITY. If any term, provision, covenant or condition of the
Plan is held to be invalid, void or otherwise unenforceable, the rest of the
Plan shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.

         11.6 NOTICE. Any notice or filing required or permitted to be given to
the Committee or a Participant shall be sufficient if in writing and hand
delivered or sent by U.S. mail to the principal office of the Company or to the
residential mailing address of the Participant. Notice shall be deemed to be
given as of the date of hand delivery or if delivery is by mail, as of the date
shown on the postmark.

governed in all respects by the laws of the State of Texas.
