                     PROVISIONS RELATING TO SPECIFIC OPTIONS

         2.1 AUTOMATIC GRANTS EVERY THREE YEARS. Subject to the availability

                                   ARTICLE III

                   GENERAL PROVISIONS RELATING TO ALL OPTIONS

         3.1 DEDICATED SHARES. The total number of shares of Stock with respect
to which Options may be granted under the Plan shall be 780,000 shares. The
shares may be treasury shares or authorized but unissued shares. The number of
shares stated in this Section 3.1 shall be subject to adjustment in accordance
with the provisions of Section 3.7.

         If any outstanding Option expires or terminates for any reason or any
Option is surrendered, the shares of Stock allocable to the unexercised portion
of that Option may again be subject to an Option under the Plan.

         3.2 OPTION PRICE. The price for which Stock may be purchased under an
Option shall be 100 percent of the Fair Market Value of the Stock on the Date of
Grant.

         3.3 AMOUNT EXERCISABLE. Each Option Agreement shall contain the
following terms of exercise:

                  (a) Except as specified below, an Option may not be exercised
         until the Optionee has served as a director of the Company for three
         years following the Date of Grant.

                  (b) If the Non-Employee Director ceases to serve on the Board
         of Directors prior to three years from the Date of Grant, for any
         reason, with or without cause, other than for death, Retirement, or
         severance for Disability, the Option shall terminate and be immediately
         forfeited. If the Non-Employee Director ceases to serve on the Board of
         Directors for any reason, with or without cause, other than for death,
         Retirement, or severance for Disability on or after three years from
         the Date of Grant, the Option shall continue in effect until ten years
         from the Date of Grant.

                  (c) If the Non-Employee Director dies prior to three years
         from the Date of Grant, the Option shall be immediately exercisable and
         shall continue in effect until ten years following the date of his
         death. If the Non-Employee Director dies on or after three years from
         the Date of Grant, the Option shall continue in effect until ten years
         from the Date of Grant. After the death of the Non-Employee Director,
         his executors, administrators or any persons to whom the Option may be
         transferred by will or by the laws of descent and distribution shall
         have the right, at any time prior to the Option's expiration to
         exercise it.

                  (d) If the Non-Employee Director Retires prior to three years
         from the Date of Grant, he shall become entitled to exercise that
         portion of the Option determined by multiplying the number of shares of
         Stock subject to the Option by a fraction, the numerator of which is
         his total whole years of service as a director of the

                                      III-1
<PAGE>   8

         Company since the Date of Grant and the denominator of which is three.
         To the extent that the Option is exercisable under the preceding
         sentence, the Option shall be exercisable until ten years following the
         date of the Non-Employee Director's Retirement and the remainder of the
         Option shall terminate immediately. If the Non-Employee Director
         Retires on or after three years from the Date of Grant, the Option
         shall continue until ten years from the Date of Grant.

                  (e) If the Non-Employee Director ceases to be a director of
         the Company due to Disability prior to three years from the Date of
         Grant, the Option shall be immediately exercisable and shall continue
         in effect until ten years following the date the Non-Employee Director
         ceased to be a director of the Company due to a Disability. If the
         Non-Employee Director ceases to be a director of the Company due to
         Disability on or after three years from the Date of Grant, the Option
         shall continue in effect until ten years from the Date of Grant.

         3.4 EXERCISE OF OPTIONS. An Optionee may exercise his Option by
delivering to the Company a written notice stating (i) that he wishes to
exercise the Option on the date the notice is delivered, (ii) the number of
shares of Stock with respect to which the Option is to be exercised, (iii) the
address to which the certificate representing such shares of Stock should be
mailed, and (iv) his social security number. In order to be effective, such
written notice shall be accompanied by (i) payment of the Option price of such
shares of Stock and (ii) payment of an amount of money necessary to satisfy any
withholding tax liability that may result from the exercise of the Option. Each
such payment shall be made by cashier's check drawn on a national banking
association and payable to the order of the Company in United States dollars.

         Unless otherwise provided in an Agreement, if, at the time of receipt
by the Company of such written notice, (i) the Company has unrestricted surplus
in an amount not less than the Option price of such shares of Stock, (ii) all
accrued cumulative preferential dividends and other current preferential
dividends on all outstanding shares of preferred stock of the Company have been
fully paid, (iii) the acquisition by the Company of its own shares of Stock for
the purpose of enabling such Optionee to exercise such Option is otherwise
permitted by applicable law and without any vote or consent of any stockholder
of the Company, and (iv) there shall have been adopted, and there shall be in
full force and effect, a resolution of the Board of Directors authorizing the
acquisition by the Company of its own shares of Stock for such purpose, then the
Optionee may deliver to the Company, in payment of the Option price of the
shares of Stock with respect to which the Option is exercised, (x) certificates
registered in the name of the Optionee that represent a number of shares of
Stock legally and beneficially owned by the Optionee (free of all liens, claims
and encumbrances of every kind) and having a fair market value on the date of
receipt by the Company of such written notice that is not greater than the
Option price of the shares of Stock with respect to which the Option is to be
exercised, such certificates to be accompanied by stock powers duly endorsed in
blank by the record holder of the shares of Stock represented by such
certificates, with the signature of such record holder guaranteed by a national
banking association (or in lieu of such certificates, other arrangements for the
transfer of such shares to the Company which are satisfactory to the Company),
and (y) if the Option price of the shares of Stock with respect to which such
Option is to be exercised exceeds such fair market value, a cashier's check
drawn on a national banking

                                      III-2
<PAGE>   9

association and payable to the order of the Company in an amount, in United
States dollars, equal to the amount of such excess plus the amount of money
necessary to satisfy any withholding tax liability that may result from the
exercise of the Option. Notwithstanding the provisions of the immediately
preceding sentence, the Committee, in its sole discretion, may refuse to accept
shares of Stock in payment of the Option price of the shares of Stock with
respect to which the Option is to be exercised and, in that event, any
certificates representing shares of Stock that were received by the Company with
such written notice shall be returned to the Optionee, together with notice by
the Company to the Optionee of the refusal of the Committee to accept such
shares of Stock. Unless otherwise provided in the Agreement, the Company, upon
approval of the Committee and in its sole discretion, upon the request of the
Optionee, may retain shares of Stock which would otherwise be issued upon
exercise of an Option to satisfy any withholding tax liability that may result
from the exercise of such Option, which shares shall be valued for such purpose
at their then Fair Market Value. If, at the expiration of seven business days
after the delivery to the Optionee of such written notice from the Company, the
Optionee shall not have delivered to the Company a cashier's check drawn on a
national banking association and payable to the order of the Company in an
amount, in United States dollars, equal to the Option price of the shares of
Stock with respect to which the Option is to be exercised, such written notice
from the Optionee to the Company shall be ineffective to exercise the Option.

         As promptly as practicable after the receipt by the Company of (i) such
written notice from the Optionee, (ii) payment, in the form required by the
foregoing provisions of this Section 3.4, of the Option price of the shares of
Stock with respect to which the Option is to be exercised, and (iii) payment, in
the form required by the foregoing provisions of this Section 3.4, of an amount
of money necessary to satisfy any withholding tax liability that may result from
the exercise of the Option, a certificate shall be issued representing the
number of shares of Stock with respect to which the Option has been so
exercised, reduced, to the extent applicable by the number of shares retained by
the Company as provided above to pay any required withholding tax, such
certificate to be registered in the name of the Optionee, provided that such
delivery shall be considered to have been made when such certificate shall have
been mailed, postage prepaid, to such optionee at the address specified for such
purpose in such written notice from the Optionee to the Company.

         3.5 NON-TRANSFERABILITY. Except as expressly provided otherwise in an
Optionee's Option Agreement, Options shall not be transferable by the Optionee
otherwise than by will or under the laws of descent and distribution, and shall
be exercisable, during the Optionee's lifetime, only by him.

         3.6 REQUIREMENTS OF LAW. The Company shall not be required to sell or
issue any shares on the exercise of the Option if the issuance of such shares
shall constitute a violation by the Non- Employee Director or the Company of any
provisions of any law or regulation of any governmental authority. The Option
shall be subject to the requirements that, if at any time the Board of Directors
shall determine that the listing, registration or qualification of the shares
subject thereto upon any securities exchange or under any state or federal law
of the United States or of any other country or governmental subdivision
thereof, or the consent or approval of any governmental regulatory body, or
investment or other representations, are necessary or desirable in connection
with the issue or purchase of shares subject thereto, the Option may not be
exercised in whole or in part unless such

                                      III-3
<PAGE>   10

listing, registration, qualification, consent, approval or representation shall
have been effected or obtained free of any condition not acceptable to the Board
of Directors. If required at any time by the Board of Directors, the Option may
not be exercised until the Non-Employee Director has delivered an investment
letter to the Company. In addition, specifically in connection with the
Securities Act of 1933 (as now in effect or hereafter amended), upon exercise of
the Option, the Company shall not be required to issue the underlying shares
unless the Board of Directors has received evidence satisfactory to it to the
effect that the Non-Employee Director will not transfer such shares except
pursuant to a registration statement in effect under such Act or unless an
opinion of counsel satisfactory to the Board of Directors has been received by
the Company to the effect that such registration is not required. Any
determination in this connection by the Board of Directors shall be final,
binding and conclusive. In the event the shares issuable on exercise of the
Option are not registered under the Securities Act of 1933, the Company may
imprint on the certificate for such shares the following legend or any other
legend which counsel for the Company considers necessary or advisable to comply
with Securities Act of 1933:

                  The shares of stock represented by this certificate have not
                  been registered under the Securities Act of 1993 or under the
                  securities laws of any state and may not be sold or
                  transferred except upon such registration or upon receipt by
                  the Corporation of an opinion of counsel satisfactory to the
                  Corporation, in form and substance satisfactory to the
                  Corporation, that registration is not required for such sale
                  or transfer.

         The Company may, but shall in no event be obligated to, register any
securities covered hereby pursuant to the Securities Act of 1933. The Company
shall not be obligated to take any other affirmative action in order to cause
the exercise of the Option or the issuance of shares of Stock pursuant thereto
to comply with any law or regulation of any governmental authority.

         3.7 CHANGES IN THE COMPANY'S CAPITAL STRUCTURE. The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its stockholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issue of bonds, debentures, preferred or prior preference stock ahead of or
affecting the Stock or the rights thereof, 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 corporate act or proceeding, whether of a similar
character or otherwise.

         If the Company shall effect a subdivision or consolidation of shares or
other capital adjustment of, or the payment of a dividend in capital stock or
other equity securities of the Company on its Stock, or other increase or
reduction of the number of shares of the Stock without receiving consideration
therefor in money, services, or property, or the reclassification of its Stock,
in whole or in part, into other equity securities of the Company, then (a) the
number, class and per share price of shares of Stock subject to outstanding
Options hereunder shall be appropriately adjusted (or in the case of the
issuance of other equity securities as a dividend on, or in a reclassification
of, the Stock, the Options shall extend to such other securities) in such a
manner as to entitle an Optionee to receive, upon exercise of an Option, for the
same aggregate cash

                                      III-4
<PAGE>   11

consideration, the same total number and class or classes of shares (or in the
case of a dividend of, or reclassification into, other equity securities, such
other securities) he would have held after such adjustment if he had exercised
his Option in full immediately prior to the event requiring the adjustment, or,
if applicable, the record date for determining stockholders to be affected by
such adjustment; and (b) the number and class of shares then reserved for
issuance under the Plan (or in the case of a dividend of, or reclassification
into, other equity securities, such other securities) shall be adjusted by
substituting for the total number and class of shares of stock then received,
the number and class or classes of shares of stock (or in the case of a dividend
of, or reclassification into, other equity securities, such other securities)
that would have been received by the owner of an equal number of outstanding
shares of Stock as a result of the event requiring the adjustment. Comparable
rights shall accrue to each Optionee in the event of successive subdivisions,
consolidations, capital adjustments, dividends or reclassifications of the
character described above.

         If the Company shall distribute to all holders of its shares of Stock
(including any such distribution made to non-dissenting stockholders in
connection with a consolidation or merger in which the Company is the surviving
corporation and in which holders of shares of Stock continue to hold shares of
Stock after such merger or consolidation) evidences of indebtedness or cash or
other assets (other than cash dividends payable out of consolidated retained
earnings not in excess of, in any one year period, the greater of (a) an amount
per share of Stock equal to $.01 per share of Stock (as the same may be adjusted
from time to time by the Board of Directors to reflect the effect of changes in
capitalization) and (b) two times the aggregate amount of dividends per share
paid during the preceding calendar year and dividends or distributions payable
in shares of Stock or other equity securities of the Company described in the
immediately preceding paragraph, but including stock or other securities of any
corporation or other entity owned by the Company), then in each case the Option
price shall be adjusted by reducing the Option price in effect immediately prior
to the record date for the determination of stockholders entitled to receive
such distribution by the fair market value, as determined in good faith by the
Board of Directors (whose determination shall be described in a statement filed
in the Company's corporate records and be available for inspection by any holder
of an Option) of the portion of the evidence of indebtedness or cash or other
assets so to be distributed applicable to one share of Stock; provided that in
no event shall the Option price be less than the par value of a share of Stock.
In the event such adjustment would result in the Option price being less than
the par value of a share of Stock but for the foregoing proviso, the terms of
the Option shall be appropriately adjusted so as to maintain the economic value
of the Option, including through an adjustment to the number of shares of Stock
subject to the Option and through a provision allowing the holder of the Option
to receive the evidence of indebtedness or cash or other assets so to be
distributed applicable to one share of Stock for each share of Stock that may be
purchased on the exercise of the Option. Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the date of the
distribution retroactive to the record date for the determination of the
stockholders entitled to receive such distribution. In addition, in the event
the Company distributes shares or other securities of a subsidiary corporation
or other entity to the holders of the Stock, the Board of Directors may, in lieu
of the adjustment provided above, make provision allowing the holder of the
Option to receive the shares or securities of the corporation or entity that is
subject to the distribution. Comparable adjustments shall be made in the event
of successive distributions of the character described above.

                                      III-5
<PAGE>   12

         If the Company shall make a tender offer for, or grant to all of its
holders of its shares of Stock the right to require the Company or any
subsidiary of the Company to acquire from such stockholders shares of Stock, at
a price in excess of the Current Market Price (a "Put Right"), or the Company
shall grant to all of its holders of its shares of Stock the right to acquire
shares of Stock for less than the Current Market Price (a "Purchase Right")
then, in the case of a Put Right, the Option price shall be adjusted by
multiplying the Option price in effect immediately prior to the record date for
the determination of stockholders entitled to receive such Put Right by a
fraction, the numerator of which shall be the number of shares of Stock then
outstanding minus the number of shares of Stock which could be purchased at the
Current Market Price for the aggregate amount which would be paid if all Put
Rights are exercised and the denominator of which is the number of shares of
Stock which would be outstanding if all Put Rights are exercised; and, in the
case of a Purchase Right, the Option price shall be adjusted by multiplying the
Option price in effect immediately prior to the record date for the
determination of the stockholders entitled to receive such Purchase Right by a
fraction, the numerator of which shall be the number of shares of Stock then
outstanding plus the number of shares of Stock which could be purchased at the
Current Market Price for the aggregate amount which would be paid if all
Purchase Rights are exercised and the denominator of which is the number of
shares of Stock which would be outstanding if all Purchase Rights are exercised.
In addition, the number of shares subject to the Option shall be increased by
multiplying the number of shares then subject to the Option by a fraction which
is the inverse of the fraction used to adjust the Option price. Notwithstanding
the foregoing, if any such Put Rights or Purchase Rights shall terminate without
being exercised, the Option price and number of shares subject to the Option
shall be appropriately readjusted to reflect the Option price and number of
shares subject to the Option which would have been in effect if such unexercised
Put Rights or Purchase Rights had never existed. Comparable adjustments shall be
made in the event of successive transactions of the character described above.

         After the merger of one or more corporations into the Company, after
any consolidation of the Company and any one or more corporations, or after any
other corporate transaction described in section 424(a) of the Code in which the
Company shall be the surviving corporation, each Optionee, at no additional
cost, shall be entitled to receive, upon any exercise of his Option, in lieu of
the number of shares as to which the Option shall then be so exercised, the
number and class of shares of stock or other equity securities to which the
Optionee would have been entitled pursuant to the terms of the agreement of
merger or consolidation if at the time of such merger or consolidation such
Optionee had been a holder of a number of shares of Stock equal to the number of
shares as to which the Option shall then be so exercised and, if as a result of
such merger, consolidation or other transaction, the holders of Stock are not
entitled to receive any shares of Stock pursuant to the terms thereof, each
Optionee, at no additional cost, shall be entitled to receive, upon exercise of
his Option, such other assets and property, including cash, to which he would
have been entitled if at the time of such merger, consolidation or other
transaction he had been the holder of the number of shares of Stock equal to the
number of shares as to which the Option shall then be so exercised. Comparable
rights shall accrue to each Optionee in the event of successive mergers or
consolidations of the character described above.

         After a merger of the Company into one or more corporations, after any
consolidation of the Company and any one or more corporations, or after any
other corporate transaction described in

                                      III-6
<PAGE>   13

section 424(a) of the Code in which the Company is not the surviving
corporation, each Optionee shall, at no additional cost, be entitled, at the
option of the surviving corporation, (i) to have his then existing Option
assumed or to have a new option substituted for the existing Option by the
surviving corporation to the transaction which is then employing him, or a
parent or subsidiary of such corporation, on a basis where the excess of the
aggregate fair market value of the shares subject to the option immediately
after the substitution or assumption over the aggregate option price of such
option is equal to the excess of the aggregate fair market value of all shares
subject to the Option immediately before such substitution or assumption over
the aggregate Option price of such shares, provided that the shares subject to
the new option must be traded on the New York or American Stock Exchange or
quoted on the National Association of Securities Dealers Automated Quotation
National Market System (or successor system) or (ii) to receive upon any
exercise of his Option, in lieu of the number of shares as to which the Option
shall then be so exercised, the securities, property and other assets, including
cash, to which the Optionee would have been entitled pursuant to the terms of
the agreement or merger or consolidation or the agreement giving rise to the
other corporate transaction if at the time of such merger, consolidation or
other transaction such Optionee had been the holder of the number of shares of
Stock equal to the number of shares as to which the Option shall then be so
exercised.

         If a corporate transaction described in section 424(a) of the Code
which involves the Company is to take place and there is to be no surviving
corporation while an Option remains in whole or in part unexercised, it shall be
cancelled by the Board of Directors as of the effective date of any such
corporate transaction but before the date each Optionee shall be provided with a
notice of such cancellation and each Optionee shall have the right to exercise
such Option in full (without regard to any limitations on exercise set forth in
or imposed by the Agreement pursuant to which such Option was granted) to the
extent it is then still unexercised during a 30-day period preceding the
effective date of such corporate transaction.

         In the event (i) the Company were to distribute to its stockholders or
otherwise divest of a majority of the stock of a subsidiary corporation that is
the principal employer of the Employee and (ii) following such distribution or
divestment the stock of the subsidiary corporation or any parent corporation of
such subsidiary corporation is listed or authorized for listing on a national
securities exchange or authorized for quotation on the National Association of
Securities Dealers Automated Quotation National Market System (or successor
system), the Board of Directors may, but shall not be required to, adjust the
terms of the Option to provide that such Option shall only represent a right to
purchase shares in such subsidiary corporation or parent corporation and the
number of shares and exercise price will be appropriately adjusted so as to
maintain the economic value of the Option. This adjustment would be in lieu of
any adjustment that might otherwise be required under this Section 3.7 for that
transaction.

         Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Stock then subject to
outstanding Options.

         For purposes of this Section 3.7, Current Market Price per share of
Stock shall mean the closing price of a share of Stock as reported by the
principal national securities exchange on which the Stock is then listed if the
Stock is then listed on a national securities exchange, or the average bid and
asked prices of a share of Stock as reported in the National Association of
Securities Dealers Automated Quotation National Market System (or successor
system) listing if the Stock is not then listed on a national securities
exchange, on the trading day immediately preceding the first trading day on
which, as a result of the establishment of a record date or otherwise, the
trading price reflects that an acquiror of Stock in the public market will not
participate in or receive the payment of any applicable dividend or
distribution.

         Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Stock then subject to
outstanding Options.

         3.8 FORM OF OPTIONS. All Options granted under this Plan will be
nonqualified stock options that are not intended to qualify as incentive stock
options under section 422 of the Internal Revenue Code of 1986, as amended.

Option Agreement which shall be subject to the terms and conditions of the Plan
and shall be signed by the Optionee and by an officer of the Company.

stockholder with respect to Stock covered by his Option until the date a stock
certificate is issued for the Stock.

                                                          Option Pursuant to the

                             STOCK OPTION AGREEMENT

         THIS STOCK OPTION AGREEMENT (this "Agreement") is made as of
____________, 2000, between GRANT PRIDECO, INC., a Delaware corporation (the
"Company"), and ________________________ (the "Optionee").

                              W I T N E S S E T H:

         WHEREAS, the Optionee serves on the Board of Directors of Weatherford
International, Inc. ("Weatherford");

         WHEREAS, on ______________________ Weatherford granted to the Optionee
an option to purchase ______ shares of Weatherford's common stock under the
[Energy Ventures, Inc. 1991 Non-Employee Director Stock Option Plan] [Energy
Ventures, Inc. Amended and Restated Non- Employee Director Stock Option Plan]
(an "Old Weatherford Option");

         WHEREAS, the Distribution Agreement by and between Weatherford
International, Inc. and the Company provides that the Company shall grant to the
Optionee an option to purchase shares of the Company's common stock, $.01 par
value ("Common Stock");

         NOW, THEREFORE, in consideration of the premises and the covenants and
agreements herein contained and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the
Optionee hereby agree as follows:

         1. Grant. (a) The Company hereby grants to the Optionee an option (the
"Option") on ______________, 2000 (the "Date of Grant") to purchase ________
shares of the Company's common stock, $.01 par value ("Common Stock"). The
Company and the Optionee agree that the Option shall be subject to the terms of
this Agreement.

         (b) The Option shall not be exercisable after __________, the term of
the Old Weatherford Option.

         (c) Subject to the terms and conditions of this Agreement, the Option
provides the Optionee with the option to purchase ________ shares of Common
Stock at a price of $_______ per share (the "Option Price").

         (d) The Option shall be considered to be a non-statutory option that is
not intended to be an incentive stock option within the meaning of section 422
of the Internal Revenue Code of 1986, as amended (the "Code").

         (e) The Option shall be immediately exercisable upon the Date of Grant.

         (f) The Optionee may exercise the Option by delivering to the Company a
written notice stating (i) that he wishes to exercise the Option on the date
such notice is so delivered, (ii) the number of shares of stock with respect to
which the Option is to be exercised, (iii) the address to

<PAGE>   2

which the certificate representing such shares of stock should be mailed, and
(iv) his social security number. In order to be effective, such written notice
shall be accompanied by payment of the Option Price. Such payment shall be made
by cashier's check drawn on a national banking association and payable to the
order of the Company in United States dollars.

         If, at the time of receipt by the Company of such written notice, (i)
the Company has unrestricted surplus in an amount not less than the Option
Price, (ii) all accrued cumulative preferential dividends and other current
preferential dividends on all outstanding shares of preferred stock of the
Company have been fully paid, (iii) the acquisition by the Company of its own
shares of stock for the purpose of enabling the Optionee to exercise the Option
is otherwise permitted by applicable law and without any vote or consent of any
stockholder of the Company, and (iv) there shall have been adopted, and there
shall be in full force and effect, a resolution of the Board of Directors of the
Company authorizing the acquisition by the Company of its own shares of stock
for such purpose, then the Optionee may deliver to the Company, in payment of
the Option Price with respect to the Option, (x) certificates registered in the
name of the Optionee that represent a number of shares of stock legally and
beneficially owned by the Optionee (free of all liens, claims and encumbrances
of every kind) and having a fair market value on the date of receipt by the
Company of such written notice that is not greater than the Option Price, such
certificates to be accompanied by stock powers duly endorsed in blank by the
record holder of the shares of stock represented by such certificates, with the
signature of such record holder guaranteed by a national banking association (or
in lieu of such certificates, other arrangements for the transfer of such shares
to the Company which are satisfactory to the Company), and (y) if the Option
Price exceeds such fair market value, a cashier's check drawn on a national
banking association and payable to the order of the Company in an amount, in
United States dollars, equal to the amount of such excess. Notwithstanding the
provisions of the immediately preceding sentence, the Committee, in its sole
discretion, may refuse to accept shares of stock in payment of the Option Price
and, in that event, any certificates representing shares of stock that were
received by the Company with such written notice shall be returned to the
Optionee, together with notice by the Company to the Optionee of the refusal of
the Committee to accept such shares of stock. If, at the expiration of seven
business days after the delivery to the Optionee of such written notice from the
Company, the Optionee shall not have delivered to the Company a cashier's check
drawn on a national banking association and payable to the order of the Company
in an amount, in United States dollars, equal to the Option Price, such written
notice from the Optionee to the Company shall be ineffective to exercise the
Option.

         As promptly as practicable after the receipt by the Company of (i) such
written notice from the Optionee and (ii) payment, in the form required by the
foregoing provisions of this Paragraph 1(f) of the Option Price, a certificate
representing the number of shares of stock with respect to which the Option has
been so exercised, such certificate to be registered in the name of the
Optionee, provided that such delivery shall be considered to have been made when
such certificate shall have been mailed, postage prepaid, the Optionee at the
address specified for such purpose in such written notice from the Optionee to
the Company.

         2. Changes in the Company's Capital Structure. The existence of the
Option shall not affect in any way the right or power of the Company or its
stockholders to make or authorize any or all adjustments, recapitalizations,
reorganizations or other changes in the Company's capital structure

                                       -2-
<PAGE>   3

or its business, or any merger or consolidation of the Company, or any issue of
bonds, debentures, preferred or prior preference stock ahead of or affecting the
Common Stock or the rights thereof, 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 corporate act or proceeding, whether of a similar character or
otherwise.

         If the Company shall effect a subdivision or consolidation of shares or
other capital adjustment of, or the payment of a dividend in capital stock or
other equity securities of the Company on, its Common Stock, or other increase
or reduction of the number of shares of the Common Stock without receiving
consideration therefor in money, services, or property, or the reclassification
of its Common Stock, in whole or in part, into other equity securities of the
Company, then (a) the number, class and per share price of shares of stock
subject to outstanding the Option shall be appropriately adjusted (or in the
case of the issuance of other equity securities as a dividend on, or in a
reclassification of, the Common Stock, the Option shall extend to such other
securities) in such a manner as to entitle the Optionee to receive, upon
exercise of the Option, for the same aggregate cash consideration, the same
total number and class or classes of shares (or in the case of a dividend of, or
reclassification into, other equity securities, such other securities) he would
have held after such adjustment if he had exercised the Option in full
immediately prior to the event requiring the adjustment, or, if applicable, the
record date for determining stockholders to be affected by such adjustment; and
(b) the number and class of shares then reserved for issuance under this
Agreement (or in the case of a dividend of, or reclassification into, other
equity securities, such other securities) shall be adjusted by substituting for
the total number and class of shares of stock then received, the number and
class or classes of shares of stock (or in the case of a dividend of, or
reclassification into, other equity securities, such other securities) that
would have been received by the owner of an equal number of outstanding shares
of Common Stock as a result of the event requiring the adjustment. Comparable
rights shall accrue the Optionee in the event of successive subdivisions,
consolidations, capital adjustments, dividends or reclassifications of the
character described above.

         If the Company shall distribute to all holders of its shares of Common
Stock (including any such distribution made to non-dissenting stockholders in
connection with a consolidation or merger in which the Company is the surviving
corporation and in which holders of shares of Common Stock continue to hold
shares of Common Stock after such merger or consolidation) evidences of
indebtedness or cash or other assets (other than cash dividends payable out of
consolidated retained earnings not in excess of, in any one year period, the
greater of (a) in an amount per share of Common Stock equal to $.01 per share of
Common Stock (as the same may be adjusted from time to time by the Board of
Directors of the Company to reflect the effect of changes in capitalization) and
(b) two times the aggregate amount of dividends per share paid during the
preceding calendar year and dividends or distributions payable in shares of
Common Stock or other equity securities of the Company described in the
immediately preceding paragraph, but including stock or other securities of any
corporation or other entity owned by the Company), then in each case the Option
Price shall be adjusted by reducing the Option Price in effect immediately prior
to the record date for the determination of stockholders entitled to receive
such distribution by the fair market value, as determined in good faith by the
Board of Directors of the Company (whose determination shall be described in a
statement filed in the Company's corporate records) of the portion of the
evidence of indebtedness or cash or other assets so to be distributed applicable
to one share of Common Stock;

                                       -3-
<PAGE>   4

provided that in no event shall the Option Price be less than the par value of a
share of Common Stock. In the event such adjustment would result in the Option
Price being less than the par value of a share of Common Stock but for the
foregoing proviso, the terms of the Option shall be appropriately adjusted so as
to maintain the economic value of the Option, including through an adjustment to
the number of shares of Common Stock subject to the Option and through a
provision allowing the holder of the Option to receive the evidence of
indebtedness or cash or other assets so to be distributed applicable to one
share of Common Stock for each share of Common Stock that may be purchased on
the exercise of the Option. Such adjustment shall be made whenever any such
distribution is made, and shall become effective on the date of the distribution
retroactive to the record date for the determination of the stockholders
entitled to receive such distribution. In addition, in the event the Company
distributes shares or other securities of a subsidiary corporation or other
entity to the holders of the Common Stock, the Board of Directors may, in lieu
of the adjustment provided above, make provision allowing the holder of the
Option to receive the shares or securities of the corporation or entity that are
subject to the distribution. Comparable adjustments shall be made in the event
of successive distributions of the character described above.

         If the Company shall make a tender offer for, or grant to all of its
holders of its shares of Common Stock the right to require the Company or any
subsidiary of the Company to acquire from such stockholders shares of, Common
Stock, at a price in excess of the Fair Market Value (a "Put Right") or the
Company shall grant to all of its holders of its shares of Common Stock the
right to acquire shares of Common Stock for less than the Fair Market Value (a
"Purchase Right") then, in the case of a Put Right, the Option Price shall be
adjusted by multiplying the Option Price in effect immediately prior to the
record date for the determination of stockholders entitled to receive such Put
Right by a fraction, the numerator of which shall be the number of shares of
Common Stock then outstanding minus the number of shares of Common Stock which
could be purchased at the Fair Market Value for the aggregate amount which would
be paid if all Put Rights are exercised and the denominator of which is the
number of shares of Common Stock which would be outstanding if all Put Rights
are exercised; and, in the case of a Purchase Right, the Option Price shall be
adjusted by multiplying the Option Price in effect immediately prior to the
record date for the determination of the stockholders entitled to receive such
Purchase Right by a fraction, the numerator of which shall be the number of
shares of Common Stock then outstanding plus the number of shares of Common
Stock which could be purchased at the Fair Market Value for the aggregate amount
which would be paid if all Purchase Rights are exercised and the denominator of
which is the number of shares of Common Stock which would be outstanding if all
Purchase Rights are exercised. In addition, the number of shares subject to the
Option shall be increased by multiplying the number of shares then subject to
the Option by a fraction which is the inverse of the fraction used to adjust the
Option Price. Notwithstanding the foregoing, if any such Put Rights or Purchase
Rights shall terminate without being exercised, the Option Price and number of
shares subject to the Option shall be appropriately readjusted to reflect the
Option Price and number of shares subject to the Option which would have been in
effect if such unexercised Put Rights or Purchase Rights had never existed.
Comparable adjustments shall be made in the event of successive transactions of
the character described above.

         After the merger of one or more corporations into the Company, after
any consolidation of the Company and any one or more corporations, or after any
other corporate transaction described in section 424(a) of the Code in which the
Company shall be the surviving corporation, the Optionee,

                                       -4-
<PAGE>   5

at no additional cost, shall be entitled to receive, upon any exercise of the
Option, in lieu of the number of shares as to which the Option shall then be so
exercised, the number and class of shares of stock or other equity securities to
which the Optionee would have been entitled pursuant to the terms of the
agreement of merger or consolidation if at the time of such merger or
consolidation the Optionee had been a holder of a number of shares of Common
Stock equal to the number of shares as to which the Option shall then be so
exercised and, if as a result of such merger, consolidation or other
transaction, the holders of Common Stock are not entitled to receive any shares
of Common Stock pursuant to the terms thereof, the Optionee, at no additional
cost, shall be entitled to receive, upon exercise of the Option, such other
assets and property, including cash, to which he would have been entitled if at
the time of such merger, consolidation or other transaction he had been the
holder of the number of shares of Common Stock equal to the number of shares as
to which the Option shall then be so exercised. Comparable rights shall accrue
to each optionee in the event of successive mergers or consolidations of the
character described above.

         After a merger of the Company into one or more corporations, after any
consolidation of the Company and any one or more corporations, or after any
other corporate transaction described in section 424(a) of the Code in which the
Company is not the surviving corporation the Optionee shall, at no additional
cost, be entitled, at the option of the surviving corporation, (i) to have the
Option assumed or to have a new option substituted for the Option by the
surviving corporation to the transaction, or a parent or subsidiary of such
corporation, on a basis where the excess of the aggregate fair market value of
the shares subject to the Option immediately after the substitution or
assumption over the aggregate option price of the option is equal to the excess
of the aggregate fair market value of all shares subject to the Option
immediately before such substitution or assumption over the aggregate Option
Price, provided that the shares subject to the new option must be traded on the
New York or American Stock Exchange or quoted on the National Association of
Securities Dealers Automated Quotation National Market System (or successor
system), or (ii) to receive upon any exercise of the Option, in lieu of the
number of shares as to which the Option shall then be so exercised, the
securities, property and other assets, including cash, to which the Optionee
would have been entitled pursuant to the terms of the agreement or merger or
consolidation or the agreement giving rise to the other corporate transaction if
at the time of such merger, consolidation or other transaction the Optionee had
been the holder of the number of shares of Common Stock equal to the number of
shares as to which the Option shall then be so exercised.

         If a corporate transaction described in section 424(a) of the Code
which involves the Company is to take place and there is to be no surviving
corporation while the Option remains in whole or in part unexercised, it shall
be cancelled by the Board of Directors of the Company as of the effective date
of any such corporate transaction but before the date the Optionee shall be
provided with a notice of such cancellation and the Optionee shall have the
right to exercise the Option in full (without regard to any limitations on
exercise set forth in or imposed by this Agreement) to the extent it is then
still unexercised during a 30-day period preceding the effective date of such
corporate transaction.

         For purposes of this Paragraph 2, Fair Market Value per share of Common
Stock shall mean the closing price of a share of Common Stock as reported by the
principal national securities exchange on which the Common Stock is then listed
if the Common Stock is then listed on a national securities exchange, or the
average bid and asked prices of a share of Common Stock as

                                       -5-
<PAGE>   6

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, on the trading day immediately
preceding the first trading day on which, as a result of the establishment of a
record date or otherwise, the trading price reflects that an acquiror of Common
Stock in the public market will not participate in or receive the payment of any
applicable dividend or distribution.

         Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock then
subject to the Options.

         3. Exercise of the Option. The Option may be exercised from time to
time as to the total number of shares that may then be issuable upon the
exercise thereof or any portion thereof in the manner and subject to the
limitations provided for in Paragraph 1 hereof.

         4. Assignment. The Option may not be transferred or assigned in any
manner by the Optionee except by will or the laws of descent and distribution,
and shall be exercisable during the Optionee lifetime only by him.

         5. Requirement of Law. The Company shall not be required to sell or
issue any shares on the exercise of the Option if the issuance of such shares
shall constitute a violation by the Optionee or the Company of any provisions of
any law or regulation of any governmental authority. The Option shall be subject
to the requirements that, if at any time the Board of Directors of the Company
shall determine that the listing, registration or qualification of the shares
subject thereto upon any securities exchange or under any state or federal law
of the United States or of any other country or governmental subdivision
thereof, or the consent or approval of any governmental regulatory body, or
investment or other representations, are necessary or desirable in connection
with the issue or purchase of shares subject thereto, the Option may not be
exercised in whole or in part unless such listing, registration, qualification,
consent, approval or representation shall have been effected or obtained free of
any condition not acceptable to the Board of Directors of the Company. If
required at any time by the Board of Directors of the Company, the Option may
not be exercised until the Optionee has delivered an investment letter to the
Company. In addition, specifically in connection with the Securities Act of 1933
(as now in effect or hereafter amended), upon exercise of the Option, the
