Administrative Committee shall have no authority to add to, delete from or

     (a) Each Non-Employee Director may from time to time execute and deliver to
the Secretary an appropriate election form designating a portion of the
Non-Employee Director's future Compensation to be deferred under the Plan up to
a maximum of 7.5 percent of such Compensation. Any election shall be applicable
only to designated Compensation earned on or after the first day of the month

Administrative Committee and until the effective date of any revocation thereof.

<PAGE>   3

or begin as provided in Section 7, which date shall be a date not less than one
year after the effective date of the election.

     (b) In the event a Participant elects to defer a portion of his
Compensation under the Plan that is equal to or greater than five percent of his
Compensation, the Company shall, during the period during which the
Participant's Compensation is being deferred, make an additional credit to the
Participant's Share Account in an amount equal to the sum of (i) 7.5 percent of
the Participant's Compensation during the period during which the Participant's
Compensation is being deferred and (ii) a percentage of such Compensation equal
to the percentage of Compensation then being deferred by the Participant under
the Plan up to a maximum of 7.5 percent of the Participant's Compensation.

     (c) Each election to defer payment of Compensation by a Participant shall
continue in effect until revoked in writing upon not less than six months' prior
notice. No revocation shall be effective with respect to any Deferred Amount
credited with respect to Compensation prior to the effective date of the new
election. The amount, if any, of the Company's additional credit to a
Participant's Share Account shall be adjusted effective as of the effective date
of each new election under the Plan by a Participant.

4.   ACCOUNTING.

     (a) The Company shall establish on its books appropriate bookkeeping
accounts for each Participant that will accurately reflect the Deferred Amount
of each Participant, including the number of Credited Shares in the
Participant's Share Account and the number of Grant Shares in the Participant's
Grant Account.

     (b) The Administrative Committee shall furnish each Participant with a
statement of the Deferred Amount, including the number of Credited Shares in the
Participant's Share Account and the number of Grant Shares in the Participant's
Grant Account, as of the end of each calendar year promptly following the end of
each calendar year.

5.   SHARE ACCOUNT.

     (a) Each Share Account shall consist of the cash amounts credited in
respect of a specific election to defer Compensation and the Credited Shares
into which prior credited amounts in the Share Account have been converted.
Except as provided in this Section 5, any cash amount credited to a Share
Account in a calendar month shall be converted, as of the end of that calendar
month, into the maximum whole number of Credited Shares that the amount so
credited would have purchased at the then Market Value.

     (b) As of the end of the calendar month during which the Company pays any
dividend on its common stock, either in cash or property other than its common
stock, each Share Account shall be credited with an amount equal to the cash
dividend per share or the cash value per share (as

                                       3
<PAGE>   4

conclusively determined by the Board) of the dividend in property other than its
common stock, times the Credited Shares in the Share Account on the dividend
record date. The amount so credited will be converted into the maximum whole
number of Credited Shares that the amount so credited could have purchased at
the then Market Value. If the Company pays any stock dividend, the Share Account
shall be credited, as of the end of the calendar month during which the stock
dividend is paid, with a number of Credited Shares equal to the number of shares
or fraction of a share of common stock paid per share of common stock as a
dividend times the Credited Shares in the Share Account on the dividend record
date.

     (c) If any distribution other than a dividend is made on, or with respect
to, the Company's common stock, or in the event of a stock split,
recapitalization, merger, consolidation or other adjustment of the Company's
common stock, an appropriate adjustment shall be made to the number of Credited
Shares in a Share Account or to the cash credited to the Share Account on the
same basis as would have been made had the Credited Shares then actually been
issued and outstanding on the record date. The Board shall resolve any questions
as to the appropriateness of any such adjustment, including, but not limited to,
values and exchange ratios, and its determination shall be binding and
conclusive.

     (d) All conversions into Credited Shares under Sections 5(a) through (c)
shall be made in full shares. Amounts not so converted shall be reflected as
credited cash in a Share Account and shall be added to any additional amounts of
credited cash subsequently available for conversion; provided, however, that in
the event the Share Account reflects only credited cash and interest thereon as
provided in Section 5(e), the cash value of such account shall not be converted
into Credited Shares.

     (e) In the event the Company's common stock is at any time not publicly
traded so as to permit the determination of the Market Value of the Credited
Shares, such value shall be determined based on such factors and criteria as the
Board shall determine in good faith to be appropriate under the circumstances.
In the event the Company's common stock shall have been converted into or
exchanged for cash, securities (other than the Company's common stock) or other
property by virtue of a merger, consolidation, share exchange, reclassification
or other similar transaction, the value of such cash, securities and other
property received by the holders of the Company's common stock per share of
common stock shall be fixed as the cash value for each Credited Share in each
Participant's Share Account and such cash value shall be credited in such Share
Account and thereafter remain credited in the Participant's Share Account until
distributed and such account shall thereafter be credited by an amount equal to
the interest that would have been earned thereon at an annual rate equal to the
published prime lending rate at the beginning of each calendar quarter at Chase
Bank of Texas, National Association computed quarterly until the cash value of
such account shall be distributed as provided in Section 7. In such event, no
further deferrals of Compensation may be made by the Participant under the Plan
and no further additional credits shall be made by the Company as provided in
Section 3(b) and any cash credits in the Share Account shall not thereafter be
converted into Credited Shares.

                                       4
<PAGE>   5

     (f) When a distribution is to commence pursuant to Section 7, a stock
certificate(s) representing the Credited Shares in the Share Account on the last
business day of the month preceding the date distribution is to commence, and
the amount of any credited cash in such Share Account will be distributed as
provided in Section 7, provided that all cash in the Share Account shall be
distributed at the time of the first distribution of stock representing Credited
Shares.

6.   GRANT ACCOUNT.

     (a) Following the Grant Spin-Off, the Committee shall credit to a
Participant's Account one non-monetary unit equal to one share of Grant Stock
for every one non-monetary unit equal to one share of Common Stock that is
deemed to be credited to his Account as of the date of the Grant Spin-Off or
subsequently credited to his Account for Compensation earned through the date of
the Grant Spin-Off.

     (b) As of the end of the calendar month during which Grant Prideco, Inc.
pays any dividend on its common stock, either in cash or property other than its
common stock, a Participant's Grant Account shall be credited with an amount
equal to the cash dividend per share or the cash value per share (as
conclusively determined by the Board) of the dividend times the Grant Shares in
the Grant Account on the dividend record date. The amount so credited will be
converted into the maximum whole number of Grant Shares that the amount so
credited could have purchased at the then Market Value. If Grant Prideco, Inc.
pays any stock dividend, the Grant Account shall be credited, as of the end of
the calendar month during which the stock dividend is paid, with a number of
Grant Shares equal to the number of shares or fraction of a share of common
stock paid per share of common stock as a dividend times the Grant Shares in the
Grant Account on the dividend record date.

     (c) If any distribution other than a dividend is made on, or with respect
to, the Grant Prideco, Inc.'s common stock, or in the event of a stock split,
recapitalization, merger, consolidation or other adjustment of Grant Prideco,
Inc.'s common stock, an appropriate adjustment shall be made to the number of
Grant Shares in a Grant Account or to the cash credited to the Grant Account on
the same basis as would have been made had the Grant Shares then actually been
issued and outstanding on the record date. The Board shall resolve any questions
as to the appropriateness of any such adjustment, including, but not limited to,
values and exchange ratios, and its determination shall be binding and
conclusive.

     (d) All conversions into Grant Shares under Sections 6(a) through (c) shall
be made in full shares. Amounts not so converted shall be reflected as credited
cash in a Grant Account and shall be added to any additional amounts of credited
cash subsequently available for conversion; provided, however, that in the event
the Grant Account reflects only credited cash and interest thereon as provided
in Section 6(e), the cash value of such account shall not be converted into
Grant Shares.

                                       5
<PAGE>   6

     (e) In the event Grant Prideco, Inc.'s common stock is at any time not
publicly traded so as to permit the determination of the Market Value of the
Grant Shares, such value shall be determined based on such factors and criteria
as the Board shall determine in good faith to be appropriate under the
circumstances. In the event Grant Prideco, Inc.'s common stock shall have been
converted into or exchanged for cash, securities (other than Grant Prideco,
Inc.'s common stock) or other property by virtue of a merger, consolidation,
share exchange, reclassification or other similar transaction, the value of such
cash, securities and other property received by the holders of Grant Prideco,
Inc.'s common stock per share of common stock shall be fixed as the cash value
for each Grant Share in each Participant's Grant Account and such cash value
shall be credited in such Grant Account and thereafter remain credited in the
Participant's Grant Account until distributed and such account shall thereafter
be credited by an amount equal to the interest that would have been earned
thereon at an annual rate equal to the published prime lending rate at the
beginning of each calendar quarter at Chase Bank of Texas, National Association
computed quarterly until the cash value of such account shall be distributed as
provided in Section 7.

     (f) When a distribution is to commence pursuant to Section 7, a stock
certificate(s) representing the Grant Shares in the Grant Account on the last
business day of the month preceding the date distribution is to commence, and
the amount of any credited cash in such Grant Account will be distributed as
provided in Section 7, provided that all cash in the Grant Account shall be
distributed at the time of the first distribution of stock representing Grant
Shares.

7.   DISTRIBUTION.

     (a) Except in the case of the death of a Participant, distribution shall
commence as of the first day of the calendar quarter coincident with or next
following the date irrevocably specified by the Participant in the applicable
election to defer.

     (b) Except in the case of the death of the Participant, distribution(s) of
stock certificate(s) representing the number of shares in the Share Account and
the Grant Account shall be either in the form of a single distribution of shares
or in approximately equal quarterly installments over a period not to exceed ten
years as irrevocably selected by the Participant in the applicable election to
defer. In the event the Participant elects to receive the deferred compensation
of shares of stock through quarterly installments, the undistributed Credited
Shares and Grant Shares shall accrue dividends when paid which will be connected
to additional Credited Shares and Grant Shares in accordance with Plan terms.
Cash in the Share Account and the Grant Account representing fractured shares
shall be distributed at the time of the next distribution of Credited Shares and
Grant Shares.

     (c) In the event of the Participant's death prior to the date specified for
his distribution or after distribution to the Participant has commenced but
before full distribution has been made, the number of the then remaining shares
in the Share Account and the Grant Account shall be paid in a single
distribution to the beneficiary or contingent beneficiary designated in the
applicable election to defer, or to the estate of the deceased Participant if
there is no surviving beneficiary or contingent

                                       6
<PAGE>   7

beneficiary. In either such event the single distribution shall be made as of
the first day of the calendar quarter following the Participant's date of death.
A Participant may change the beneficiary or contingent beneficiary from time to
time with respect to any election to defer by filing with the Administrative
Committee a notice of change of beneficiary. No change shall be effective unless
received by the Administrative Committee prior to the date of the Participant's
death.

8.   MISCELLANEOUS.

     (a) The Board may amend or terminate the Plan at any time; provided,
however, (i) no amendment may be made that would accelerate or change the date
of distribution with respect to Compensation theretofore deferred, and (ii) any
amendment or termination of the Plan shall not affect the rights of Participants
or beneficiaries to payment, in accordance with Section 7, of amounts credited
to Participants' account hereunder at the time of such amendment or termination.

     (b) The Plan does not create a trust in favor of a Participant, his
designated beneficiary or beneficiaries, or any other person claiming on his
behalf, and the obligation of the Company is solely a contractual obligation to
make payments due hereunder. In this regard, the balance in any account shall be
considered a liability of the Company and the Participant's right thereto shall
be the same as any unsecured general creditor of the Company. Neither the
Participant nor any other person shall acquire any right, title, or interest in
or to any Deferred Amount outstanding under the Plan other than the actual
payment of such Deferred Amount in accordance with the terms of the Plan.

     (c) 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 hereunder shall in any manner be liable for or subject
to the debts, contracts, liabilities or torts of the person entitled to such
benefit. If any Participant or beneficiary shall become bankrupt or attempt to
anticipate, alienate, sell, assign, pledge, encumber or charge any right or
benefit hereunder, then such right or benefit shall in the discretion of a
majority of the Board, excluding the affected Participant, cease and terminate;
and in such event, the Company may hold or apply the same or any part thereof
for the benefit of the Participant or his beneficiary, his spouse, children or
other dependents, at any time and in such proportion as a majority of the Board,
excluding the affected Participant, may deem proper. Any statement to the
contrary notwithstanding, the Company may apply any Deferred Amount to satisfy,
in whole or in part, any indebtedness of a Participant to the Company.

     (d) The terms of the Plan shall be binding upon the heirs, executors,
administrators, personal representatives, successors and assigns of all parties
in interest.

     (e) The headings have been inserted for convenience only and shall not
affect the meaning or interpretation of the Plan.

                                       7
<PAGE>   8
     (f) Each Participant shall submit to the Administrative Committee his
current mailing address. It shall be the duty of each Participant to notify the
Administrative Committee of any change of address. In the absence of such
notice, the Administrative Committee shall be entitled for all purposes to rely
on the last-known address of the Participant.

     (g) Any amount payable to or for the benefit of a minor, an incompetent
person or other person incapable of receipting therefor shall be deemed paid
when paid to such person's guardian or to the party providing or reasonably
appearing to provide for the care of such person, and such payment shall fully
discharge the Company and the Board with respect thereto.

     (h) Nothing in the Plan or any amendment thereto shall give a Participant,
or any beneficiary of a Participant, a right not specifically provided therein.
Nothing in the Plan or any amendment thereto shall be construed as giving a
Participant the right to be retained as a member of the Board.

     (i) If the context requires it, words of one gender when used in the Plan
will include the other gender, and words used in the singular or plural will
include the other.

     (j) The Plan will be construed, administered and governed in all respects
by the laws of the State of Texas.

     IN WITNESS WHEREOF, the Company caused this Agreement to be executed this
13th day of April, 2000.

                       AMENDMENT TO STOCK OPTION PROGRAMS

     WHEREAS, the Board of Directors of Weatherford International, Inc. (the
"Company") has approved of the distribution to the Company's stockholders of all
of the stock of Grant Prideco, Inc. (the "Spin-Off") pursuant to the terms and
conditions set forth in the Distribution Agreement by and between the Company
and Grant Prideco, Inc. (the "Distribution Agreement");

     NOW, THEREFORE, the Company agrees as follows:

     (1) Effective as of the Distribution Date as defined in the Distribution
Agreement (the "Distribution Date"), the Energy Ventures, Inc. Employees' Stock
Option Plan, the Energy Ventures, Inc. 1992 Employee Stock Option Plan, the
Weatherford Enterra, Inc. 1991 Stock Option Plan, Taro Industries Limited Stock
Option Plan and the Weatherford International, Inc. 1998 Employee Stock Option
Plan are hereby amended by adding to each the following provisions:

     Notwithstanding any other provision of the Plan, the per-share exercise
price of each option granted under the Plan prior to September of 1998 shall be
adjusted pursuant to the application of the following formula: E (W-G)/W where E
is the original exercise price of the option; W is the market value per share of
Weatherford International, Inc.'s common stock, $1.00 par value ("WII Common
Stock"), as of the close of market on the last trading day before
"when-distributed" trading begins as reported by the New York Stock Exchange
("NYSE"); and G is the market value of a share of Grant Prideco, Inc. common
stock, $.01 par value ("GP Common Stock") determined initially by taking the
average of the high and low trading prices on the NYSE on the first full trading
date after "when-distributed" trading begins; and, following 30 consecutive
trading days after "when-distributed" trading begins, for options outstanding on
such date, the average of the last sales price per share of GP Common Stock on
the NYSE for each of the 30 consecutive trading days beginning on the date
"when-distributed" trading begins. Notwithstanding any other provision of the
Plan, if an optionee continues to be an employee of Grant Prideco, Inc. or any
of its affiliates (a "Grant Company") after the date as of which the
distribution by Weatherford International, Inc. to its stockholders of the stock
of Grant Prideco, Inc. is effective (the "Distribution Date"), he shall not be
deemed to terminate employment with Weatherford International, Inc. or its
subsidiaries within the meaning of the Plan until he is no longer an employee of
any Grant Company.

     Further, notwithstanding any other provision of the Plan, each option
granted under the Plan after August 31, 1998 to an optionee who continues to be
an employee of a Grant Company after the Distribution Date shall be canceled
upon the Distribution Date.

     Further, notwithstanding any other provision of the Plan, any option
granted under the Plan after August 31, 1998 to an optionee who remains an
employee of Weatherford International, Inc.

<PAGE>   2

or any of its subsidiaries or other affiliates, other than a Grant Company,
after the Distribution Date shall be adjusted as follows. The number of shares
of WII Common Stock for which such an option will be exercisable and the
exercise price for such option will be determined as provided in the following
formula:

    The adjusted exercise price for the option will equal             E (W-G)/W

    The number of shares of WII Common Stock subject to the
    adjusted option will equal                                        NE/Pw

    Where   E  =  The original exercise price of the option;

            N  =  The original number of shares of WII Common Stock subject to
                  the option;

            G  =  The market value of a share of GP Common
                  Stock (a) initially based on the average of the high and low
                  trading prices on the NYSE on the first full trading date
                  after "when-distributed" trading begins, and (b) following 30
                  consecutive trading days after "when-distributed" trading
                  begins, for options remaining outstanding on such date, the
                  average of the last sales price per share of GP Common Stock
                  on the NYSE for each of the 30 consecutive trading days
                  beginning on the date "when-distributed" trading begins; and

            W  =  The market value per share of WII Common Stock as of the close
                  of market on the last trading day before "when-distributed"
                  trading begins as reported by the NYSE; and

            Pw =  The adjusted exercise price of the option determined in
                  accordance with the formula set forth above.

     (2) Effective as of the Distribution Date, the Energy Ventures, Inc.
Amended and Restated Non-Employee Director Stock Option Plan and the Energy
Ventures, Inc. 1991 Non-Employee Director Stock Option Plan are hereby amended
by adding thereto the following provisions:

     Notwithstanding any other provision of the Plan, the per-share exercise
price of each option granted under the Plan shall be adjusted pursuant to the
application of the following formula: E (W-G)/W where E is the original exercise

following 30 consecutive trading days after "when-distributed" trading begins,
for options outstanding on such date, the average of the last sales price per

     (3) Effective as of the Distribution Date, each option agreement and
warrant agreement entered into by the Company after August 31, 1998 with respect
to an optionee who remains an employee of the Company or any of its subsidiaries
or other affiliates other than Grant Prideco, Inc. or any of its subsidiaries or
other affiliates after the Distribution Date or who remains a non-employee

Stock"), for which such an option will be exercisable and the exercise price for
such option will be determinated as provided in the following formula:
