                                   ARTICLE I

                      PURPOSE, SHARE COMMITMENT AND INTENT

     1.1  PURPOSE.  The purpose of the Plan is to provide Employees of the
Company and its Affiliates that adopt the Plan an opportunity to purchase shares
of Stock through periodic offerings of options to purchase shares of Stock at a
discount and thus develop a stronger incentive to work for the continued success
of the Company and its Affiliates.

     1.2  SHARE COMMITMENT.  The aggregate number of shares of Stock authorized
to be sold pursuant to Options granted under the Plan is 1,200,000, subject to
adjustment as provided in this Section. In computing the number of shares of
Stock available for grant, any shares of Stock relating to Options which are
granted, but which subsequently lapse, are cancelled or are otherwise not
exercised by the final date for exercise, shall be available for future grants
of Options.

     In the event of any stock dividend, split-up, recapitalization, merger,
consolidation, combination or exchange of shares, or the like, as a result of
which shares shall be issued in respect of the outstanding shares of Stock, or
the shares of Stock shall be changed into the same or a different number of the
same or another class of stock, the total number of shares of Stock authorized
to be committed to the Plan, the number of shares of Stock subject to each
outstanding Option, the Option Price applicable to each Option, and/or the
consideration to be received upon exercise of each Option shall be appropriately
adjusted by the Committee. In addition, the Committee shall, in its sole
discretion, have authority to provide for (a) acceleration of the Exercise Date
of outstanding Options or (b) the conversion of outstanding Options into cash or
other property to be received in certain of the transactions specified in this
paragraph above upon the completion of the transaction.

     1.3  INTENT.  It is the intention of the Company to have the Plan qualify
as an "employee stock purchase plan" under section 423 of the Code. Therefore,
the provisions of the Plan are to be construed to govern participation in a
manner consistent with the requirements of section 423 of the Code.

     1.4  SHAREHOLDER APPROVAL.  To be effective, the Plan must be approved by
the shareholders of the Company within 12 months after the Plan is adopted. The
approval of shareholders must comply with all applicable provisions of the
corporate charter, bylaws and applicable laws of the jurisdiction prescribing
the method and degree of shareholder approval required for the issuance of
corporate stock or options.

                                   ARTICLE II

                                  DEFINITIONS

     The words and phrases defined in this Article shall have the meaning set
out in these definitions throughout the Plan, unless the context in which any
word or phrase appears reasonably requires a broader, narrower, or different
meaning.

     2.1  "AFFILIATE" means any parent corporation and any subsidiary
corporation. The term "parent corporation" means any corporation (other than the
Company) in an unbroken chain of corporations ending with the Company if, at the
time of the action or transaction, each of the corporations (other than the
Company) owns stock possessing 50 percent or more of the total combined voting
power of all classes of stock in one of the other corporations in the chain. The
term "subsidiary corporation" means any corporation (other than the Company) in
an unbroken chain of corporations beginning with the Company if, at the time of
the granting of the Option, each of the corporations other than the last
corporation in the unbroken chain owns stock possessing 50 percent or more of
the total combined voting power of all classes of stock in one of the other
corporations in the chain.

     2.2  "AUTHORIZED LEAVE OF ABSENCE" means a bona fide leave of absence from
service with the Company or an Affiliate if the period of the leave does not
exceed 90 days, or, if longer, so long as the individual's right to reemployment
with the Company or an Affiliate is guaranteed either by statute or contract.

     2.14  "FIVE PERCENT OWNER" means an owner of five percent or more of the
total combined voting power of all classes of stock of the Company or any
Affiliate. An individual is considered to own any stock that is owned directly
or indirectly by or for his brothers and sisters (whether by whole or

indirectly, by or for a corporation, partnership, estate or trust is considered
as owned proportionately by or for its shareholders, partners, or beneficiaries.
An individual is considered to own stock that he may purchase under outstanding
options. The determination of the percentage of the total combined voting power
of all classes of stock of the Company or any Affiliate that is owned by an
individual is made by comparing the voting power or value of the shares owned
(or treated as owned) by the individual to the aggregate voting power of all
shares actually issued and outstanding immediately after the grant of the option
to the individual. The aggregate voting power or value of all shares actually
issued and outstanding immediately after the grant of the option does not
include the voting power or value of treasury shares or shares authorized for
issue under outstanding options held by the individual or any other person.

the day the Committee grants all eligible Employees an Option under the Plan.

Stock at the Option Price on the Exercise Date.

     2.18  "OPTION PRICE" means the price to be paid for each share of Stock
upon exercise of an Option, which shall be 85 percent of the lesser of (a) the
Fair Market Value of a share of Stock on the Grant Date or (b) the Fair Market
Value of a share of Stock on the Exercise Date.

employment with his Employer is more than 20 hours per week and more than 5
months during any calendar year.

     2.22  "RETIREMENT" means the occurrence of the Participant's voluntary
termination of employment with the Company and all Affiliates after he has
attained the age of 65 and completed ten years of uninterrupted employment with
the Company and/or any Affiliate, including any predecessor thereto.

share, or, in the event that the outstanding shares of common stock are later
changed into or exchanged for a different class of shares or securities of the
Company or another corporation, that other share or security. Shares of Stock,
when issued, may be represented by a certificate or by book or electronic entry.

     2.24  "TRADING DAY" means a day on which the principal securities exchange
on which the shares of Stock are listed is open for trading.

                                  ARTICLE III

                                  ELIGIBILITY

     3.1  GENERAL REQUIREMENTS.  Subject to Section 3.2, each Regular, Full Time
Employee of each Employer is eligible to participate in the Plan for a given
Offering Period if he is in the employ of an Employer on the Grant Date and he
enrolls in the Plan and authorizes payroll deductions for such Offering Period
in accordance with procedures established by the Committee. Participation in the
Plan is voluntary.

     3.2  LIMITATIONS UPON PARTICIPATION.  No Employee shall be granted an
Option to the extent that the Option would:

          (a)  cause the Employee to be a Five Percent Owner immediately after
     the grant;

          (b)  permit the Employee to purchase shares of Stock under all
     employee stock purchase plans, as defined in section 423 of the Code, of
     the Company and all Affiliates at a rate which exceeds $25,000 in Fair
     Market Value of the shares of Stock (determined at the time the Option is
     granted) for each calendar year in which the option granted to the Employee
     is outstanding at any time as provided in sections 423 and 424 of the Code;
     or

          (c)  permit the Employee to purchase shares of Stock in excess of the
     number of shares of Stock determined under Section 4.1.

In addition, no Option shall be granted to an Employee who resides in a country
whose laws make participation in the Plan impractical.

                                   ARTICLE IV

                                 PARTICIPATION

     4.1  GRANT OF OPTION.  Effective as of the Grant Date of each Offering
Period, the Committee shall grant an Option to each Participant which shall be
exercisable on the Exercise Date only through funds accumulated by the Employee
through payroll deductions made during the Offering Period. The Option shall be
for that number of whole shares of Stock that may be purchased by the amount in
the Participant's payroll deduction account on the Exercise Date at the Option
Price. The Committee may establish and announce to Employees prior to an
Offering Period, a maximum number of shares of Stock that may be purchased by an
Employee during the Offering Period. If the Committee does not specify a maximum
number of shares of
                                       B-3
<PAGE>

Stock that may be purchased during an Offering Period, the maximum number of
shares shall be that number of shares that may be purchased with the aggregate
amount of payroll deductions for the Offering Period authorized by the Employee
(determined assuming that the Employee will continue payroll deductions at the
same rate in effect on the Grant Date throughout the Offering Period) assuming
that the purchase price per share is 85 percent of the Fair Market Value of a
share of Stock on the Date of Grant.

     4.2  PAYROLL DEDUCTION.  For an Employee to participate during a given
Offering Period, he must authorize deductions from his Base Pay prior to the
beginning of the Offering Period in accordance with procedures established by
the Committee. Unless the Participant changes the rate of his payroll
deductions, his payroll deductions shall continue through the last pay date
prior to the Exercise Date. A Participant may not make additional payments to
his Plan account.

     4.3  PAYROLL DEDUCTIONS CONTINUING.  A Participant's payroll deduction
authorization shall remain in effect for all ensuing Offering Periods until
changed by him in accordance with procedures established by the Committee.

     4.4  RIGHT TO STOP PAYROLL DEDUCTIONS.  A Participant shall have the right
to discontinue his payroll deduction authorization in accordance with procedures
established by the Committee.

     4.5  ACCOUNTING FOR FUNDS.  As of each payroll deduction period, the
Employer shall cause to be credited to the Participant's payroll deduction
account in a ledger established for that purpose the funds withheld from and
attributable to the Employee's cash compensation for that period. No interest
shall be credited to the Participant's payroll deduction account at any time.
The obligation of the Employer to the Participant for this account shall be a
general corporate obligation and shall not be funded through a trust nor secured
by any assets which would cause the Participant to be other than a general
creditor of the Employer.

     4.6  EMPLOYER'S USE OF FUNDS.  All payroll deductions received or held by
an Employer may be used by the Employer for any corporate purpose, and the
Employer shall not be obligated to segregate such payroll deductions.

     4.7  RETURN OF FUNDS.  Except as specified herein, as soon as
administratively practicable after the expiration of an Offering Period, payroll
deductions that are not used to purchase Stock during such Offering Period will
be refunded to the Participants. In accordance with procedures established by
the Committee, an Employer may be permitted to apply a Participant's unused
payroll deductions to purchase additional shares of Stock during a subsequent
Offering Period, but only if the amount so applied does not exceed the value of
a fractional share that the Participant could not purchase during the preceding
Offering Period (because purchases of fractional shares are not permitted under
the Plan).

                                   ARTICLE V

                  IN SERVICE WITHDRAWAL, TERMINATION OR DEATH

     5.1  IN SERVICE WITHDRAWAL.  A Participant may, at any time on or before 15
days prior to the Exercise Date, or such other date as shall be selected by the
Committee from time to time, elect to withdraw all of the funds then credited to
his Plan account by giving notice in accordance with the rules established by
the Committee. The amount elected to be withdrawn by the Participant shall be
paid to him as soon as administratively feasible. Any election by a Participant
to withdraw his cash balance under the Plan terminates his right to exercise his
Option on the Exercise Date and his entitlement to elect any further payroll
deductions for the then-current Offering Period. If the Participant wishes to
participate in any future Offering Period, he must file a new payroll deduction
election within the time frame required by the Committee for participation for
that Offering Period.

     5.2  TERMINATION OF EMPLOYMENT FOR ANY REASON OTHER THAN DEATH; OR
RETIREMENT OR DISABILITY WHICH OCCURS MORE THAN THREE MONTHS PRIOR TO THE
EXERCISE DATE.  If a Participant's employment with the Company and all
Affiliates is terminated for any reason other than death prior to the Exercise
Date, or if the Participant's employment with the Company and all Affiliates is
terminated more than three months prior to the Exercise Date as a result of
Retirement of Disability, the Option granted to the Participant for that
                                       B-4
<PAGE>

Offering Period shall lapse. If a Participant is on an Authorized Leave of
Absence, for purposes of the Plan, the Participant's employment with the Company
and all Affiliates shall be deemed to be terminated on the later of the 91st day
of such leave or the date through which the Participant's employment is
guaranteed either by statute or contract. The Participant's funds then credited
to his Plan Account shall be returned to him as soon as administratively
feasible.

     5.3  TERMINATION OF EMPLOYMENT DUE TO DEATH.  If a Participant's employment
with the Company and all Affiliates is terminated due to death, the
Participant's Beneficiary (or such other person as may be entitled to amounts
credited to the Participant's account under Section 10.1) will have the right to
elect, either to:

          (a)  withdraw all of the funds then credited to his Plan account as of
     his termination date; or

          (b)  exercise the Option for the maximum number of whole shares of
     Stock that can be purchased at the Option Price on the last day of the
     Offering Period (in which the Participant's termination of employment with
     the Company and all Affiliates occurs).

     The Participant's Beneficiary (or such other person as may be entitled to
amounts credited to the Participant's account under Section 10.1) must make such
election by giving written notice to the Committee in accordance with procedures
established by the Committee. In the event the Beneficiary (or such other person
as may be entitled to amounts credited to the Participant's account under
Section 10.1) elects to withdraw the funds, any accumulated funds credited to
the Participant's Plan account as of the date of his termination of employment
with the Company and all Affiliates will be delivered as soon as
administratively practicable thereafter.

     5.4  TERMINATION OF EMPLOYMENT DUE TO RETIREMENT OR DISABILITY WITHIN THREE
MONTHS PRIOR TO THE EXERCISE DATE.  If a Participant's employment with the
Company and all Affiliates is terminated, within three months prior to the
Exercise Date, due to Retirement or Disability, the Participant (or the
Participant's personal representative or legal guardian in the event of
Disability) will have the right to elect either to:

          (a)  withdraw all of the funds then credited to his Plan account as of
     his termination date; or

          (b)  exercise the Option for the maximum number of whole shares of
     Stock that can be purchased at the Option Price on the last day of the
     Offering Period (in which the Participant's termination of employment with
     the Company and all Affiliates occurs).

     5.5  The Participant (or, if applicable, such other person designated in
the first paragraph of this Section 5.4) must make such election by giving
written notice to the Committee in accordance with procedures established by the
Committee. Any accumulated funds credited to the Participant's Plan account as
of the date of his termination of employment with the Company and all Affiliates
will be delivered to or on behalf of the Participant as soon as administratively
practicable thereafter.

                                   ARTICLE VI

                               EXERCISE OF OPTION

     6.1  PURCHASE OF SHARES OF STOCK.  Subject to Section 3.2, on the Exercise
Date of each Offering Period, each Participant's payroll deduction account shall
be used to purchase the maximum number of whole shares of Stock that can be
purchased at the Option Price for that Offering Period. If in any Offering
Period the total number of shares of Stock to be purchased by all Participants
exceeds the number of shares of Stock committed to the Plan, then each
Participant shall be entitled to purchase only his pro rata portion of the
shares of Stock remaining available under the Plan based on the balances in each
Participant's payroll deduction account as of the Exercise Date. After the
purchase of all shares of Stock available on the Exercise Date, all Options
granted for the Offering Period to the extent not used are terminated because no
Option shall remain exercisable after the Exercise Date.

     6.2  ACCOUNTING FOR SHARES OF STOCK.  After the Exercise Date of each
Offering Period, a report shall be given to each Participant stating the amount
of his payroll deduction account, the number of shares of Stock purchased and
the Option Price.

                                       B-5
<PAGE>

     6.3  ISSUANCE OF SHARES OF STOCK.  As soon as administratively feasible
after the end of the Offering Period, the Committee shall advise the appropriate
officer of the Company that the terms of the Plan have been complied with and
that it is appropriate for the officer to cause to be issued the shares of Stock
upon which Options have been exercised under the Plan. The Committee may
determine in its discretion the manner of delivery of the shares of Stock
purchased under the Plan, which may be by electronic account entry into new or
existing accounts, delivery of shares of Stock certificates or any other means
as the Committee, in its discretion, deems appropriate. The Committee may, in
its discretion, hold the shares of Stock certificate for any shares of Stock or
cause it to be legended in order to comply with the securities laws of the
applicable jurisdiction, or should the shares of Stock be represented by book or
electronic account entry rather than a certificate, the Committee may take such
steps to restrict transfer of the shares of Stock as the Committee considers
necessary or advisable to comply with applicable law.

                                  ARTICLE VII

                                 ADMINISTRATION

     7.1  POWERS.  The Committee has the exclusive responsibility for the
general administration of the Plan, and has all powers necessary to accomplish
that purpose, including but not limited to the following rights, powers, and
authorities:

          (a)  to make rules for administering the Plan so long as they are not
     inconsistent with the terms of the Plan;

          (b)  to construe all provisions of the Plan;

          (c)  to correct any defect, supply any omission, or reconcile any
     inconsistency which may appear in the Plan;

          (d)  to select, employ, and compensate at any time any consultants,
     accountants, attorneys, and other agents the Committee believes necessary
     or advisable for the proper administration of the Plan;

          (e)  to determine all questions relating to eligibility, Fair Market
     Value, Option Price and all other matters relating to benefits or
     Participants' entitlement to benefits;

          (f)  to determine all controversies relating to the administration of
     the Plan, including but not limited to any differences of opinion arising
     between an Employer and a Participant, and any questions it believes
     advisable for the proper administration of the Plan; and

          (g)  to delegate any clerical or recordation duties of the Committee
     as the Committee believes is advisable to properly administer the Plan.

     7.2  QUORUM AND MAJORITY ACTION.  A majority of the Committee constitutes a
quorum for the transaction of business. The vote of a majority of the members
present at any meeting shall decide any question brought before that meeting. In
addition, the Committee may decide any question by a vote, taken without a
meeting, of a majority of its members via telephone, computer, fax or any other
media of communication.

     7.3  STANDARD OF JUDICIAL REVIEW OF COMMITTEE ACTIONS.  The Committee has
full and absolute discretion in the exercise of each and every aspect of its
authority under the Plan. Notwithstanding anything to the contrary, any action
taken, or ruling or decision made by the Committee in the exercise of any of its
powers and authorities under the Plan shall be final and conclusive as to all
parties other than the Company, including without limitation all Participants
and their beneficiaries, regardless of whether the Committee or one or more of
its members may have an actual or potential conflict of interest with respect to
the subject matter of the action, ruling, or decision. No final action, ruling,
or decision of the Committee shall be subject to de novo review in any judicial
proceeding; and no final action, ruling, or decision of the Committee may be set
aside unless it is held to have been arbitrary and capricious by a final
judgment of a court having jurisdiction with respect to the issue.

                                  ARTICLE VIII

                      ADOPTION OF PLAN BY OTHER EMPLOYERS

     8.1  ADOPTION PROCEDURE.  With the approval of the Committee, any Affiliate
may adopt the Plan for all or any classification of its Employees by depositing
with the Sponsor:

          (a)  a duly executed adoption agreement setting forth agreement to be
     bound as an Employer by all the terms, provisions, conditions and
     limitations of the Plan except those, if any, specifically set forth in the
     adoption agreement;

          (b)  all other information required by the Sponsor; and

          (c)  the written consent of the Sponsor to the adoption of the Plan.

     8.2  NO JOINT VENTURE IMPLIED.  The document which evidences the adoption
of the Plan by an Affiliate shall become a part of the Plan. However, neither
the adoption of the Plan by an Affiliate nor any act performed by it in relation
to the Plan shall create a joint venture or partnership relation between it and
the Company or any other Affiliate.

                                   ARTICLE IX

                     TERMINATION AND AMENDMENT OF THE PLAN

     9.1  TERMINATION.  The Company may, by action of the Committee, terminate
the Plan at any time and for any reason. The Plan shall automatically terminate
upon the purchase by Participants of all shares of Stock committed to the Plan,
unless the number of shares of Stock committed to the Plan is increased by the
Committee or the Board and approved by the shareholders of the Company. Upon
termination of the Plan, as soon as administratively feasible there shall be
refunded to each Participant the remaining funds in his payroll deduction
account. The termination of the Plan shall not affect the current Options
already outstanding under the Plan to the extent there are shares of Stock
committed, unless the Participants agree.

     9.2  AMENDMENT.  The Committee has the right to modify, alter or amend the
Plan at any time and from time to time to any extent that it deems advisable,
including, without limiting the generality of the foregoing, any amendment to
the Plan deemed necessary to ensure compliance with section 423 of the Code. The
Committee may suspend the operation of the Plan for any period as it may deem
advisable. However, no amendment or suspension shall operate to reduce any
amounts previously allocated to a Participant's payroll deduction account, to
reduce a Participant's rights with respect to shares of Stock previously
purchased and held on his behalf under the Plan nor to affect the current Option
a Participant already has outstanding under the Plan without the Participant's
agreement. Any amendment changing the aggregate number of shares of Stock to be
committed to the Plan, the class of employees eligible to receive Options under
the Plan or the description of the group of corporations eligible to adopt the
Plan must have shareholder approval as set forth in Section 1.4.

                                   ARTICLE X

                                 MISCELLANEOUS

     10.1  DESIGNATION OF BENEFICIARY.

          (a)  A Participant may file a written designation of a Beneficiary who
     is to receive any cash and shares of Stock credited to the Participant's
     account under the Plan. If a Participant is married and the designated
     Beneficiary is not the Participant's spouse, written spousal consent shall
     be required for the designation to be effective.

          (b)  A Participant may change his designation of a Beneficiary at any
     time by written notice. If a Participant dies when he has not validly
     designated a Beneficiary under the Plan, the Company shall deliver such
     shares of Stock and cash to the executor or administrator of the estate of
     the Participant, or if

                                       B-7
<PAGE>

     no such executor or administrator has been appointed (to the knowledge of
     the Company), the Company, in its discretion, may deliver such shares of
     Stock and cash to the spouse or to any one or more dependents or relatives
     of the Participant, or if no spouse, dependent or relative is known to the
     Company, then to such other person as the Company may designate.

     10.2  PLAN NOT AN EMPLOYMENT CONTRACT.  The adoption and maintenance of the
Plan is not a contract between any Employer and its Employees which gives any
Employee the right to be retained in its employment. Likewise, it is not
intended to interfere with the rights of any Employer to discharge any Employee
at any time or to interfere with the Employee's right to terminate his
employment at any time.

     10.3  ALL PARTICIPANTS' RIGHTS ARE EQUAL.  All Participants will have the
same rights and privileges under the Plan as required by section 423 of the Code
and Department of Treasury Regulation section 1.423-2(f).

     10.4  OPTIONS ARE NOT TRANSFERABLE.  No Option granted a Participant under
the Plan is transferable by the Participant otherwise than by will or the laws
of descent and distribution, and must be exercisable, during his lifetime, only
by him. In the event any Participant attempts to violate the terms of this
Section, any Option held by the Participant shall be terminated by the Company
and, upon return to the Participant of the remaining funds in his payroll
deduction account, all of his rights under the Plan will terminate.

     10.5  VOTING OF SHARES OF STOCK.  Shares of Stock held under the Plan for
the account of each Participant shall be voted by the holder of record of those
shares of Stock in accordance with the Participant's instructions.

     10.6  NO RIGHTS OF SHAREHOLDER.  No eligible Employee or Participant shall
by reason of participation in the Plan have any rights of a shareholder of the
Company until he acquires shares of Stock as provided in the Plan.

     10.7  GOVERNMENTAL REGULATIONS.  The obligation to sell or deliver the
shares of Stock under the Plan is subject to the approval of all governmental
authorities required in connection with the authorization, purchase, issuance or
sale of the shares of Stock.

     10.8  NOTICES.  All notices and other communication in connection with the
Plan shall be in the form specified by the Committee and shall be deemed to have
been duly given when sent to the Participant at his last known address or to his
designated personal representative or beneficiary, or to the Employer or its
designated representative, as the case may be.

     10.9  INDEMNIFICATION OF COMMITTEE.  In addition to all other rights of
indemnification as they may have as directors or as members of the Committee,
the members of the Committee shall be indemnified by the Company against the
reasonable expenses, including attorneys' fees, actually and necessarily
incurred in connection with the defense of any action, suit or proceeding, or in
connection with any appeal, to which they or any of them may be a party by
reason of any action taken or failure to act under or in connection with the
Plan or any Option granted under the Plan, and against all amounts paid in
settlement (provided the settlement is approved by independent legal counsel
selected by the Company) or paid by them in satisfaction of a judgment in any
action, suit or proceeding, except in relation to matters as to which it is
adjudged in the action, suit or proceeding, that the Committee member is liable
for gross negligence or willful misconduct in the performance of his duties.

     10.10  TAX WITHHOLDING.  At the time a Participant's Option is exercised or
at the time a Participant disposes of some or all of the shares of Stock
purchased under the Plan, the Participant must make adequate provision for the
Employer's federal, state or other tax withholding obligations, if any, which
arise upon the exercise of the Option or the disposition of the shares of Stock.
At any time, the Employer may, but shall not be obligated to, withhold from the
Participant's compensation the amount necessary for the Employer to meet
applicable withholding obligations.

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

                                       B-8
<PAGE>

     10.12  SEVERABILITY.  Each provision of the Plan may be severed. If any
provision is determined to be invalid or unenforceable, that determination shall
not affect the validity or enforceability of any other provision.

     10.13  PERSONS BASED OUTSIDE OF THE UNITED STATES.  Notwithstanding any
provision of the Plan to the contrary, in order to comply with the laws in other
countries in which the Company and its Affiliates operate or have Employees, the
Committee, in its sole discretion, shall have the power and authority to:

          (a)  determine which Affiliates shall be covered by the Plan;

          (b)  determine which persons employed outside the United States are
     eligible to participate in the Plan;

          (c)  modify the terms and conditions of any Option granted to persons
     who are employed outside the United States to comply with applicable
     foreign laws;

          (d)  establish subplans and modify exercise procedures and other terms
     and procedures to the extent such actions may be necessary or advisable;
     and

          (e)  take any action, before or after an Option is granted, that it
     deems advisable to obtain or comply with any necessary local government
     regulatory exemptions or approvals.

     Notwithstanding the foregoing, the Committee may not take any actions
hereunder, and no Options shall be granted, that would violate section 423 of
the Code, any securities law or governing statute or any other applicable law.
Any income derived under the Plan shall not be treated as a part of an
Employee's regular compensation or salary for purposes of computing statutorily
mandated severance benefits or other statutorily mandated benefits in foreign
jurisdictions.

     Any subplans and modifications to Plan terms and procedures established
under this Section 10.13 by the Committee shall be attached to the Plan document
as Appendices.

     10.14  GOVERNING LAW; PARTIES TO LEGAL ACTIONS.  The provisions of the Plan
shall be construed, administered, and governed under the laws of the State of
Texas and, to the extent applicable, by the securities, tax, employment and
other laws of the United States.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (this "Agreement") by and between Grant
Prideco, Inc., a Delaware corporation (the "Company"), and Matthew Fitzgerald
(the "Executive"), is effective as of January 12, 2004.

                              W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that it is in the best interests of the Company and its stockholders
to retain the Executive and to induce the employment of the Executive for the
long term benefit of the Company;

         WHEREAS, the Board does not contemplate the termination of the
Executive during the term hereof and the Board and the Executive expect that the
Executive will be retained for at least the three year period contemplated
herein; and

         WHEREAS, to accomplish these objectives, the Board has caused the
Company to enter into this Agreement.

         NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

1.       Employment.

                  (a)      The Company hereby agrees that the Company or an
affiliated company will continue the Executive in its employ, and the Executive
hereby agrees to remain in the employ of the Company or an affiliate subject to
the terms and conditions of this Agreement, during the Employment Period (as
defined below).

                  (b)      The "Employment Period" shall mean the period
commencing on the date hereof and ending on the second anniversary of the date
hereof.; provided, however, that commencing on the date one year after the date
hereof, and on each annual anniversary of such date (such date and each annual
anniversary thereof shall be hereinafter referred to as the "Renewal Date"),
unless previously terminated, the Employment Period shall be automatically
extended so as to terminate two years after such Renewal Date, unless at least
60 days prior to the Renewal Date the Company shall give notice to the Executive
that the Contract Period shall not be so extended.

         2.       Terms of Employment.

                  (a)      Position and Duties.

                           (i)      During the Employment Period, (A) the
         Executive's position (including status, offices, titles and reporting
         requirements, authority, duties and responsibilities) shall be Senior
         Vice President and Chief Financial Officer of the Company and such
         other executive positions as may be assigned to him and (B) the
         Executive's services shall be performed at any location within 50 miles
         from downtown, Houston, Texas.

<PAGE>

                           (ii)     During the Employment Period, and excluding
         any periods of vacation and sick leave to which the Executive is
         entitled, the Executive agrees to devote reasonable attention and time
         during normal business hours to the business and affairs of the Company
         and, to the extent necessary to discharge the responsibilities assigned
         to the Executive hereunder, to use the Executive's reasonable best
         efforts to perform faithfully and efficiently such responsibilities.
         During the Employment Period it shall not be a violation of this
         Agreement for the Executive to (A) serve on corporate, civic or
         charitable boards or committees, (B) deliver lectures, fulfill speaking
         engagements or teach at educational institutions and (C) manage
         personal investments, so long as such activities do not significantly
         interfere with the performance of the Executive's responsibilities as
         an employee of the Company in accordance with this Agreement. It is
         expressly understood and agreed that to the extent that any such
         activities have been conducted by the Executive prior to the date
         hereof, the continued conduct of such activities (or the conduct of
         activities similar in nature and scope thereto) subsequent to the date
         hereof shall not thereafter be deemed to interfere with the performance
         of the Executive's responsibilities to the Company.

                  (b)      Compensation.

                           (i)      Base Salary. During the Employment Period,
         the Executive shall receive an annual base salary of $275,000 ("Annual
         Base Salary"), which shall be paid at a monthly rate. During the
         Employment Period, the Annual Base Salary shall be reviewed at least
         annually; provided, however, that a salary increase shall not
         necessarily be awarded as a result of such review. Any increase in
         Annual Base Salary may not serve to limit or reduce any other
         obligation to the Executive under this Agreement. Annual Base Salary
         shall not be reduced after any such increase. The term Annual Base
         Salary as utilized in this Agreement shall refer to Annual Base Salary
         as so increased.

                           (ii)     Annual Bonus. The Executive shall be
         eligible for an annual bonus (the "Annual Bonus") for each fiscal year
         ending during the Employment Period on the same basis as other
         executive officers under the Company's executive officer annual
         incentive program. Each such Annual Bonus shall be paid no later than
         the end of the third month of the fiscal year next following the fiscal
         year for which the Annual Bonus is awarded or at such time as bonuses
         are paid generally to the employees of the Company, unless the
         Executive shall elect to defer the receipt of such Annual Bonus
         pursuant to a Company sponsored deferred compensation plan in effect.

                           (iii) Incentive, Savings and Retirement Plans. During
         the Employment Period, the Executive shall be entitled to participate
         in all incentive, savings and retirement plans, practices, policies and
         programs applicable generally to the Executive's peer executives of the
         Company and its affiliated companies, but in no event shall such plans,
         practices, policies and programs provide the Executive with incentive
         opportunities (measured with respect to both regular and special
         incentive opportunities, to the extent, if any, that such distinction
         is applicable), savings opportunities and retirement benefit
         opportunities, in each case, less favorable, in the aggregate, than the
         most favorable of those provided by the Company and its affiliated
         companies for the Executive under such plans, practices, policies and
         programs as in effect on the date hereof. As used in this Agreement,

                                        2
<PAGE>

         the term "affiliated companies" shall include any company controlled
         by, controlling or under common control with the Company.

                           (iv)     Welfare Benefit Plans. During the Employment
         Period, the Executive and/or the Executive's family, as the case may
         be, shall be eligible to participate in and shall receive all benefits
         under welfare benefit plans, practices, policies and programs provided
         by the Company and its affiliated companies (including, without
         limitation, medical, prescription, dental, disability, salary
         continuance, employee life, group life, accidental death and travel
         accident insurance plans and programs) to the extent applicable
         generally to the Executive's peer executives of the Company and its
         affiliated companies, but in no event shall such plans, practices,
         policies and programs provide the Executive with benefits that are less
         favorable, in the aggregate, than such plans, practices, policies and
         programs as may be in effect from time to time.

                           (v)      Expenses. During the Employment Period, the
         Executive shall be entitled to receive prompt reimbursement for all
         reasonable expenses incurred by the Executive in accordance with the
         most favorable policies, practices and procedures of the Company and
         its affiliated companies as may be in effect from time to time.

                           (vi)     Fringe Benefits. During the Employment
         Period, the Executive shall be entitled to fringe benefits (including,
         without limitation, financial planning services, payment of club dues,
         a car allowance or use of an automobile and payment of related
         expenses, as appropriate) in accordance with the most favorable plans,
         practices, programs and policies of the Company as may be in effect
         from time to time.

                           (vii)    Vacation. During the Employment Period, the
         Executive shall be entitled to paid vacation in accordance with the
         most favorable plans, policies, programs and practices of the Company
         and its affiliated companies as may be in effect from time to time
         (provided a minimum of three weeks vacation per year is provided).

         3.       Termination of Employment.

                  (a)      Death or Disability. The Executive's employment shall
terminate automatically upon the Executive's death during the Employment Period.
If the Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below), it may give to the Executive written notice in accordance with
Section 10(b) of this Agreement of its intention to terminate the Executive's
employment. In such event, the Executive's employment with the Company shall
terminate effective 30 days after receipt of such notice by the Executive (the
"Disability Effective Date"), provided that within the 30-day period after such
receipt, the Executive shall not have returned to full-time performance of the
Executive's duties. For purposes of this Agreement, "Disability" shall mean the
absence of the Executive from the Executive's duties with the Company on a
full-time basis for 180 calendar days as a result of incapacity due to mental or
physical illness that is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Executive or the
Executive's legal representative.

                                       3
<PAGE>

                  (b)      Cause. The Company may terminate the Executive's
employment during the Employment Period for Cause. For purposes of this
Agreement, "Cause" shall mean:

                           (i)      the willful and continued failure of the
         Executive to perform substantially the Executive's duties with the
         Company or one of its affiliates (other than any such failure resulting
         from incapacity due to physical or mental illness), after a written
         demand for substantial performance is delivered to the Executive by the
         Board or the Chief Executive Officer of the Company that specifically
         identifies the manner in which the Board or Chief Executive Officer
         believes that the Executive has not substantially performed the
         Executive's duties, or

                           (ii)     the willful engaging by the Executive in
         illegal conduct or gross misconduct that is materially and demonstrably
         injurious to the Company.

                  For purposes of this provision, no act, or failure to act, on
the part of the Executive shall be considered "willful" unless it is done, or
omitted to be done, by the Executive in bad faith or without reasonable belief
that the Executive's action or omission was in the best interests of the
Company. Any act, or failure to act, based upon authority given pursuant to a
resolution duly adopted by the Board or upon the instructions of the Chief
Executive Officer or based upon the advice of counsel for the Company shall be
conclusively presumed to be done, or omitted to be done, by the Executive in
good faith and in the best interests of the Company. The cessation of employment
of the Executive shall not be deemed to be for Cause unless and until there
shall have been delivered to the Executive a copy of a resolution duly adopted
by the affirmative vote of not less than three-quarters of the entire membership
of the Board at a meeting of the Board called and held for such purpose (after
reasonable notice is provided to the Executive and the Executive is given an
opportunity, together with counsel, to be heard before the Board), finding that,
in the good faith opinion of the Board, the Executive is guilty of the conduct
described in subparagraph (i) or (ii) above, and specifying the particulars
thereof in detail.

                  (c)      Good Reason. The Executive's employment may be
terminated by the Executive during the Employment Period for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean:

                           (i)      the assignment to the Executive of any
         duties inconsistent in any respect with the Executive's position
         (including status, offices, titles and reporting requirements),
         authority, duties or responsibilities as contemplated by Section 2(a)
         of this Agreement, or any other action by the Company that results in a
         diminution in such position, authority, duties or responsibilities,
         excluding for this purpose an isolated, insubstantial and inadvertent
         action not taken in bad faith and that is remedied by the Company
         promptly after receipt of notice thereof given by the Executive;

                           (ii)     the assignment to the Executive of any
         duties inconsistent in any respect with the Executive's position
         (including status, offices, titles and reporting requirements),
         authority, duties or responsibilities as contemplated by Section 2(a)
         of this Agreement, or any other action by the Company that results in a
         diminution in such position, authority, duties or responsibilities, if
         there were to occur a merger, consolidation or other business
         combination involving the Company where the Company ceases to be
         publicly

                                       4
<PAGE>

         traded and following the transaction the Executive does not have the
         status, office, title and reporting requirements at the ultimate parent
         company that are substantially similar to that which the Executive has
         with the Company;

                           (iii)    any failure by the Company to comply with
         any of the provisions of Section 2(b) of this Agreement, other than an
         isolated, insubstantial and inadvertent failure not occurring in bad
         faith and that is remedied by the Company promptly after receipt of
         notice thereof given by the Executive;

                           (iv)     the Company's requiring the Executive to be
         based at any office or location other than as provided in Section
         2(a)(i)(B) hereof or the Company's requiring the Executive to travel on
         Company business to a substantially greater extent than reasonably
         required in the conduct of Executive's duties hereunder;

                           (v)      any purported termination by the Company of
         the Executive's employment otherwise than as expressly permitted by
         this Agreement; or

                           (vi)     any failure by the Company to comply with
         and satisfy Section 9(c) of this Agreement.

                  For purposes of this Section 3(c), any good faith
determination of "Good Reason" made by the Executive shall be conclusive.

                  (d)      Notice of Termination. Any termination during the
Employment Period by the Company for Cause, or by the Executive for Good Reason,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 10(b) of the Agreement. For purposes of this
Agreement, a "Notice of Termination" means a written notice that (i) indicates
the specific termination provision in this Agreement relied upon, (ii) to the
extent applicable, sets forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated and (iii) if the Date of Termination (as defined
below) is other than the date of receipt of such notice, specifies the
termination date (which date shall be not more than 30 days after the giving of
such notice). The failure by the Executive or the Company to set forth in the
Notice of Termination any fact or circumstance that contributes to a showing of
Good Reason or Cause shall not waive any right of the Executive or the Company,
respectively, from asserting such fact or circumstance in enforcing the
Executive's or the Company's rights hereunder.

                  (e)      Date of Termination. "Date of Termination" shall
mean:

                           (i)      if the Executive's employment is terminated
         by the Company for Cause, or by the Executive for Good Reason, the date
         of receipt of the Notice of Termination or any later date specified
         therein, as the case may be;

                           (ii)     if the Executive's employment is terminated
         by the Company other than for Cause, death or Disability, the Date of
         Termination shall be the date on which the Company notifies the
         Executive of such termination; and

                                       5
<PAGE>

                           (iii)    if the Executive's employment is terminated
         by reason of death or Disability, the Date of Termination shall be the
         date of death of the Executive or the Disability Effective Date, as the
         case may be.

         4.       Obligations of the Company Upon Termination.

                  (a)      Good Reason; Other than For Cause, Death or
Disability: Not Following a Change of Control. If, during the Employment Period,

                           (i)      The Company shall pay to the Executive in a
         lump sum in cash within 30 days after the Date of Termination the
         aggregate of the following amounts:

                                    (A)      the sum of (1) the Executive's
                  Annual Base Salary through the Date of Termination to the
                  extent not theretofore paid, (2) the product of (x) the higher
                  of (I) the highest Annual Bonus received by the Executive from
                  the Company over the preceding two year period, including any
                  bonus or portion thereof that has been earned but deferred and
                  (II) in the event a bonus has been earned but not yet paid in
                  connection with the most recently completed fiscal year during
                  the Employment Period, the amount of such bonus that has been
                  earned plus any portion thereof that has been earned but
                  deferred , if any (such higher amount being referred to as the
                  "Highest Annual Bonus" for purposes of Section 4(a), (b), (c)
                  and (d)) and (y) a fraction, the numerator of which is the
                  number of days in the current fiscal year through the Date of
                  Termination, and the denominator of which is 365, and (3) any
                  compensation previously deferred by the Executive under a plan
                  sponsored by the Company (together with any accrued interest
                  or earnings thereon), and any accrued vacation pay, in each
                  case to the extent not theretofore paid (the sum of the
                  amounts described in clauses (1), (2) and (3) shall be
                  hereinafter referred to as the "Accrued Obligations" for
                  purposes of this Sections 4(a), (b), (c) and (d)), and

                                    (B)      an amount equal to two times the
                  sum of (i) the then current Annual Base Salary of the
                  Executive and (ii) the Highest Annual Bonus, and

                                    (C)      an amount equal to the total of the

                  under the Company's 401(k) Savings Plan (the "401(k) Plan") or
                  any other deferred compensation plan during the 12-month
                  period immediately preceding the month of the Executive's Date
                  of Termination multiplied by two, such amount to be grossed up
                  so that the amount the Executive actually receives after
                  payment of any federal or state taxes payable thereon equals
                  the amount first described above.

                           (ii)     For a period of two years from the
         Executive's Date of Termination (the "Remaining Contract Term" for
         purposes of this Sections 4(a), (b) and (c)) or such longer period as
         may be provided by the terms of the appropriate plan, program, practice
         or policy, the Company shall continue benefits to the Executive and/or
         the Executive's family

                                       6

         equal to those that would have been provided to them in accordance with
         the plans, programs, practices and policies described in Section
         2(b)(iv) of this Agreement if the Executive's employment had not been
         terminated; provided, however, that with respect to any of such plans,
         programs, practices or policies requiring an employee contribution, the
         Executive shall continue to pay the monthly employee contribution for
         same, and provided further, that if the Executive becomes reemployed by
         another employer and is eligible to receive medical or other welfare
         benefits under another employer provided plan, the medical and other
         welfare benefits described herein shall be secondary to those provided
         under such other plan during such applicable period of eligibility;

                           (iii)    The Company shall, at its sole expense as
         incurred, provide the Executive with outplacement services, the scope
         and provider of which shall be selected by the Executive in his sole
         discretion;

                           (iv)     All benefits under the Company's Executive
         Deferred Compensation Plan , 401(k) Plan, stock compensation plans and
         any other similar plans, including without limitation any stock options
         or restricted stock held by the Executive, not already vested shall be
         100% vested, to the extent such vesting is permitted under the Code (as
         defined below);

                           (v)      All country club memberships, luncheon clubs
         and other memberships that the Company was providing for the
         Executive's use at the time Notice of Termination is given shall, to
         the extent possible, be transferred and assigned to the Executive at no
         cost to the Executive (other than income taxes owed), the cost of
         transfer, if any, to be borne by the Company;

                           (vi)     The Company shall either transfer to the
         Executive ownership and title to the Executive's company car at no cost
         to the Executive (other than income taxes owed) or, if the Executive
         receives a monthly car allowance in lieu of a Company car, pay the
         Executive a lump sum in cash within 30 days after the Executive's Date
         of Termination equal to the Executive's annual car allowance multiplied
         by two;

                           (vii)    To the extent not theretofore paid or
         provided, the Company shall timely pay or provide to the Executive any
         other amounts or benefits required to be paid or provided or that the
         Executive is eligible to receive under any plan, program, policy or
         practice or contract or agreement of the Company and its affiliated
         companies (such other amounts and benefits shall be hereinafter
         referred to as the "Other Benefits" for purposes of this Sections 4(a),
         (b), (c) and (d)); and

                           (viii)   The foregoing payments are intended to
         compensate the Executive for a breach of the Company's obligations and
         place Executive in substantially the same position had the employment
         of the Executive not been so terminated as a result of a breach by the
         Company.

                  (b)      Death. If Executive's employment is terminated by
reason of the Executive's death during the Employment Period, this Agreement
shall terminate without further obligations to the Executive's legal
representatives under this Agreement, other than for payment of Accrued

                                       7
<PAGE>

Obligations and the timely payment or provision of Other Benefits. Accrued
Obligations shall be paid to the Executive's estate or beneficiaries, as

With respect to the provision of Other Benefits, the term Other Benefits as
utilized in this Section 4(b) shall include, without limitation, and the

programs, practices and policies relating to death benefits, if any, in effect
generally on the date hereof or, if more favorable, those in effect on the date
of the Executive's death.

                  (c)      Disability. If the Executive's employment is
terminated by reason of the Executive's Disability during the Employment Period,
this Agreement shall terminate without further obligations to the Executive,
other than for payment of Accrued Obligations and the timely payment or
provision of Other Benefits. Accrued Obligations shall be paid to the Executive
in a lump sum in cash within 30 days after the Date of Termination. With respect
to the provision of Other Benefits, the term Other Benefits as utilized in this
Section 4(c) shall include, without limitation, and the Executive shall be
entitled after the Disability Effective Date to receive, disability and other
benefits at least equal to the most favorable benefits generally provided by the
Company and its affiliated companies to the Executive's disabled peer executives
and/or their families in accordance with such plans, programs, practices and
policies relating to disability, if any, in effect generally on the date hereof
or, if more favorable, those in effect at the time of the Disability.

                  (d)      Cause; Other Than for Good Reason. If the Executive's
employment is terminated for Cause during the Employment Period, this Agreement
shall terminate without further obligations to the Executive, other than the
obligation to pay to the Executive (x) his or her Annual Base Salary through the
Date of Termination, (y) the amount of any compensation previously deferred by
the Executive and (z) Other Benefits, in each case to the extent theretofore
unpaid. If the Executive voluntarily terminates employment during the Employment
Period, excluding a termination for Good Reason, this Agreement shall terminate
without further obligations to the Executive, other than for Accrued Obligations
and the timely payment or provision of Other Benefits. In such case, all Accrued
Obligations shall be paid to the Executive in a lump sum in cash within 30 days
after the Date of Termination subject to such other options or restrictions as
provided by law.

                  (e)      Good Reason; Other than For Cause, Death or
Disability: Following a Change of Control. If, during the Employment Period, the
Company shall terminate the Executive's employment other than for Cause, death
or Disability, or the Executive shall terminate employment for Good Reason, in

         lump sum in cash within 30 days after the Date of Termination the
         aggregate of the following amounts:

                                    (A)      the sum of (1) the Executive's
                  Annual Base Salary through the Date of Termination to the
                  extent not theretofore paid, (2) the product of (x) the higher
                  of (I) the highest Annual Bonus received by the Executive from
                  the Company over the preceding three year period, including
                  any bonus or portion thereof that has been earned but deferred
                  and (II) in the event a bonus has been earned but not yet

                                       8

                  year during the Employment Period, the amount of such bonus
                  that has been earned plus any portion thereof that has been
                  earned but deferred , if any (such higher amount being
                  referred to as the "Highest Annual Bonus" for purposed of this
                  section 4(e)) and (y) a fraction, the numerator of which is
                  the number of days in the current fiscal year through the Date
                  of Termination, and the denominator of which is 365, and (3)
                  any compensation previously deferred by the Executive under a
                  plan sponsored by the Company (together with any accrued
                  interest or earnings thereon), and any accrued vacation pay,
                  in each case to the extent not theretofore paid, and

                                    (B)      an amount equal to three times the
                  sum of (i) the then current Annual Base Salary of the
                  Executive and (ii) the Highest Annual Bonus, and

                                    (C)      an amount equal to the total of the
                  employer matching contributions credited to the Executive
                  under the Company's 401(k) Savings Plan (the "401(k) Plan") or
                  any other deferred compensation plan during the 12-month
                  period immediately preceding the month of the Executive's Date
                  of Termination multiplied by three, such amount to be grossed
                  up so that the amount the Executive actually receives after
                  payment of any federal or state taxes payable thereon equals
                  the amount first described above.

                           (ii)     For a period of three years from the
         Executive's Date of Termination (the "Remaining Contract Term" for
         purposes of this Section 4(e)) or such longer period as may be provided
         by the terms of the appropriate plan, program, practice or policy, the
         Company shall continue benefits to the Executive and/or the Executive's
         family equal to those that would have been provided to them in
         accordance with the plans, programs, practices and policies described
         in Section 2(b)(iv) of this Agreement if the Executive's employment had
         not been terminated; provided, however, that with respect to any of
         such plans, programs, practices or policies requiring an employee
         contribution, the Executive shall continue to pay the monthly employee
         contribution for same, and provided further, that if the Executive
         becomes reemployed by another employer and is eligible to receive
         medical or other welfare benefits under another employer provided plan,

                           (iv)     All benefits under the Company's Executive
         Deferred Compensation Plan and the 401(k) Plan and any other similar
         plans, but excluding any stock options or restricted stock held by the
         Executive (the terms of such stock options or restricted stock to be
         governed by the agreements and plans governing such grants), not
         already vested shall be 100% vested, to the extent such vesting is
         permitted under the Code (as defined below);

                           (v)      All country club memberships, luncheon clubs

         Executive's use at the time Notice of Termination is

                                       9
<PAGE>

         given shall, to the extent possible, be transferred and assigned to the
         Executive at no cost to the Executive (other than income taxes owed),

                           (vii)    To the extent not theretofore paid or
         provided, the Company shall timely pay or provide to the Executive any
         other amounts or benefits required to be paid or provided or that the
         Executive is eligible to receive under any plan, program, policy or
         practice or contract or agreement of the Company and its affiliated
         companies, and

                           (viii)   The foregoing payments are intended to
         compensate the Executive for a breach of the Company's obligations and
         place Executive in substantially the same position had the employment
         of the Executive not been so terminated as a result of a breach by the
         Company.

         5.       Other Rights. Except as provided hereinafter, nothing in this
Agreement shall prevent or limit the Executive's continuing or future
participation in any plan, program, policy or practice provided by the Company
or any of its affiliated companies and for which the Executive may qualify, nor
shall anything herein limit or otherwise affect such rights as the Executive may

practice or program of or any contract or agreement with the Company or any of
its affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or contract or
agreement. It is expressly agreed by the Executive that he or she shall have no
right to receive, and hereby waives any entitlement to, any severance pay or
similar benefit under any other plan, policy, practice or program of the
Company. In addition, if the Executive has an employment or similar agreement
with the Company at the Date of Termination, he or she agrees that he or she
shall have the right to receive all of the benefits provided under this
Agreement or such other agreement, whichever one, in its entirety, the Executive
chooses, but not both agreements, and when the Executive has made such election,
the other agreement shall be superseded in its entirety and shall be of no
further force and effect. The Executive also agrees that to the extent he or she
may be eligible for any severance pay or similar benefit under any laws
providing for severance or termination benefits, such other severance pay or
similar benefit shall be coordinated with the benefits owed hereunder, such that
the Executive shall not receive duplicate benefits.

         6.       Full Settlement.

                  (a)      No Rights of Offset. The Company's obligation to make
the payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be

                                       10
<PAGE>

affected by any set-off, counterclaim, recoupment, defense or other claim, right
or action that the Company may have against the Executive or others.

                  (b)      No Mitigation Required. In no event shall the
Executive be obligated to seek other employment or take any other action by way
of mitigation of the amounts payable to the Executive under any of the
provisions of this Agreement and such amounts shall not be reduced whether or
not the Executive obtains other employment.

                  (c)      Legal Fees. The Company agrees to pay as incurred, to
the full extent permitted by law, all legal fees and expense that the Executive
may reasonably incur as a result of any contest (regardless of the outcome
thereof) by the Company or the Executive of the validity or enforceability of,
or liability under, any provision of this Agreement or any guarantee of
performance thereto (including as a result of any contest by the Executive about
the amount of any payment pursuant to this Agreement), plus in each case
interest on any delayed payment at the applicable Federal rate provided for in
Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended (the
"Code").

         7.       Certain Additional Payments by the Company.

                  (a)      Although this Agreement is not being entered into in
connection with or contingent upon a change of control of the Company, anything
in this Agreement to the contrary notwithstanding and except as set forth below,
in the event it shall be determined that any payment or distribution by the
Company to or for the benefit of the Executive (whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise, but determined without regard to any additional payments required
under this Section 7) (a "Payment") would be subject to the excise tax imposed
by Section 4999 of the Code or any interest or penalties are incurred by the
Executive with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including, without limitation, any income taxes (and any
interest and penalties imposed with respect thereto) and Excise Tax imposed upon
the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payments. Notwithstanding the foregoing
provisions of this Section 7(a), if it shall be determined that the Executive is
entitled to a Gross-Up Payment, but that the Executive, after taking into
account the Payments and the Gross-Up Payment, would not receive a net after-tax
benefit of at least $50,000 (taking into account both income taxes and any
Excise Tax) as compared to the net after-tax proceeds to the Executive resulting
from an elimination of the Gross-Up Payment and a reduction of the Payments, in
the aggregate, to an amount (the "Reduced Amount") such that the receipt of
Payments would not give rise to any Excise Tax, then no Gross-Up Payment shall
be made to the Executive and the Payments, in the aggregate, shall be reduced to
the Reduced Amount.

                  (b)      Subject to the provisions of Section 7(c), all
determinations required to be made under this Section 7, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by Ernst & Young LLP or, as provided below, such other certified public
accounting firm as may be designated by the Executive (the "Accounting Firm"),
which shall
<PAGE>

provide detailed supporting calculations both to the Company and the Executive
within 15 business days after the receipt of notice from the Executive that
there has been a Payment, or such earlier time as is requested by the Company.
In the event that the Accounting Firm is serving as accountant or auditor for
the individual, entity or group effecting the change of control, the Executive
shall appoint another nationally recognized accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accounting Firm hereunder). All fees and expenses of the Accounting
Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined
pursuant to this Section 7, shall be paid by the Company to the Executive within
five days after the receipt of the Accounting Firm's determination. Any
determination by the Accounting Firm shall be binding upon the Company and the
Executive. As a result of the uncertainty in the application of Section 4999 of
the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Gross-Up Payments that will not have been made by
the Company should have been made ("Underpayment"), consistent with the
calculations required to be made hereunder. In the event that the Company
exhausts its remedies pursuant to Section 7(c) and the Executive thereafter is
required to make a payment of any Excise Tax, the Accounting Firm shall
determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for the benefit of the
Executive.

                  (c)      The Executive shall notify the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment (or an additional Gross-Up
Payment) in the event the IRS seeks higher payment. Such notification shall be
given as soon as practicable, but no later than ten business days after the
Executive is informed in writing of such claim, and shall apprise the Company of
the nature of such claim and the date on which such claim is requested to be
paid. The Executive shall not pay such claim prior to the expiration of the
30-day period following the date on which he gives such notice to the Company
(or such shorter period ending on the date that any payment of taxes with
respect to such claim is due). If the Company notifies the Executive in writing
prior to the expiration of such period that it desires to contest such claim,
the Executive shall:

                           (i)      give the Company any information reasonably
         requested by the Company relating to such claim,

                           (ii)     take such action in connection with
         contesting such claim as the Company shall reasonably request in
         writing from time to time, including, without limitation, accepting
         legal representation with respect to such claim by an attorney
         reasonably selected by the Company,

                           (iii)    cooperate with the Company in good faith
          effectively to contest such claim, and

                           (iv)     permit the Company to participate in any
         proceedings relating to such claims; provided, however, that the
         Company shall bear and pay directly all costs and expenses (including
         additional interest and penalties) incurred in connection with such
         costs and shall indemnify and hold the Executive harmless, on an
         after-tax basis, for any Excise Tax or income tax (including interest
         and penalties with respect thereto) imposed as a result of such
         representation and payment of costs and expenses. Without limitation on
         the foregoing provisions of this Section 7(c), the Company shall
         control all proceedings taken in
<PAGE>

         connection with such contest and, at its sole option, may pursue or
         forego any and all administrative appeals, proceedings, hearings and
         conferences with the taxing authority in respect of such claim and may,
         at its sole option, either direct the Executive to pay the tax claimed
         and sue for a refund or contest the claim in any permissible manner,
         and the Executive agrees to prosecute such contest to determination
         before any administrative tribunal, in a court of initial jurisdiction
         and in one or more appellate courts, as the Company shall determine;
         provided, however, that if the Company directs the Executive to pay
         such claim and sue for a refund, the Company shall advance the amount
         of such payment to the Executive, on an interest-free basis, and shall
         indemnify and hold the Executive harmless, on an after-tax basis, from
         any Excise Tax or income tax (including interest or penalties with
         respect thereto) imposed with respect to such advance or with respect
         to any imputed income with respect to such advance; and further
         provided that any extension of the statute of limitations relating to
         payment of taxes for the taxable year of the Executive with respect to
         which such contested amount is claimed to be due is limited solely to
         such contested amount. Furthermore, the Company's control of the
         contest shall be limited to issues with respect to which a Gross-Up
         Payment would be payable hereunder and the Executive shall be entitled
         to settle or contest, as the case may be, any other issues raised by
         the Internal Revenue Service or any other taxing authority.

                  (d)      If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 7(c), the Executive becomes entitled
to receive any refund with respect to such claim, the Executive shall (subject
to the Company's complying with the requirements of Section 7(c)) promptly pay
to the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the receipt by the
Executive of an amount advanced by the Company pursuant to Section 7(c), a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then such advance shall be forgiven and
shall not be required to be repaid and the amount of such advance shall offset,
to the extent thereof, the amount of Gross-Up Payment required to be paid.

         8.       Confidential Information. The Executive shall hold in a
fiduciary capacity for the benefit of the Company all secret or confidential
information, knowledge or data relating to the Company or any of its affiliated
companies, and their respective businesses, that shall have been obtained by the
Executive during the Executive's employment by the Company or any of its
affiliated companies, provided that it shall not apply to information that is or
shall become public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement), information
that is developed by the Executive independently of such information, or
knowledge or data or information that is disclosed to the Executive by a third
party under no obligation of confidentiality to the Company. After termination
of the Executive's employment with the Company, the Executive shall not, without
the prior written consent of the Company or as may otherwise be required by law
or legal process, communicate or divulge any such information, knowledge or data
to anyone other than the Company and those designated by it. In no event shall
an asserted violation of the provisions of this Section 8 constitute a basis for
deferring or withholding any amounts otherwise payable to the Executive under
this Agreement.

         9.       Successors.

                  (a)      This Agreement is personal to the Executive and shall
not be assignable by the Executive otherwise than by will or the laws of descent
and distribution. This Agreement shall inure to the benefit of and be
enforceable by the Executive's legal representatives.

<PAGE>

                  (b)      This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns.

                  (c)      The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid that assumes and agrees to perform this Agreement by operation of law,
or otherwise.

         10.      Miscellaneous.

                  (a)      THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REFERENCE TO PRINCIPLES
OF CONFLICT OF LAWS. The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect. This Agreement may not be
amended or modified otherwise than by a written agreement executed by the

under this Agreement such Federal, state, local or foreign taxes as shall be
required to be withheld pursuant to any applicable law or regulation.

                  (e)      The Executive's or the Company's failure to insist
upon strict compliance with any provision of this Agreement or the failure to
assert any right the Executive or the Company may have hereunder, including,
without limitation, the right of the Executive to terminate employment for Good
Reason pursuant to Section 3(c)(i)-(v) of this Agreement, shall not be deemed to
be a waiver of such provision or right or any other provision or right of this
Agreement.

                  (f)      A "Change of Control" shall mean:

                           (i)      The acquisition by any individual, entity or
group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person") of
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) of 50 percent or more of either (A) the then outstanding shares of
common stock of the Company (the "Outstanding Company Common Stock") or (B) the
combined voting power of the then outstanding voting securities of the Company
entitled to vote generally in the election of directors (the "Outstanding
Company Voting Securities"); provided, however, that for purposes of this
subsection (i), the following acquisitions shall not constitute a Change of
Control:

                                    (A)      any acquisition directly from the
Company; or

                                    (B)      any acquisition by the Company; or

                                    (C)      any acquisition by any employee
benefit plan (or related trust) sponsored or maintained by the Company or any
corporation controlled by the Company; or

                                    (D)      any acquisition by any corporation
pursuant to a transaction that complies with clauses (A), (B) and (C) of
subsection (iii) of this Section 1(c); or

                           (ii)     Individuals, who, as of the date hereof,
constitute the Board (the "Incumbent Board") cease for any reason to constitute
at least a majority of the Board; provided, however, that any individual
becoming a director subsequent to the date hereof whose election, or nomination
for election by the Company's stockholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual was a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

                           (iii)    Consummation of a reorganization, merger or
consolidation or sale or other disposition of all or substantially all of the
assets of the Company (a "Corporate Transaction") in each case, unless,
following such Corporate Transaction, (A) all or substantially all of the
individuals and entities who were the beneficial owners, respectively, of the
Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Corporate
<PAGE>

Transaction beneficially own, directly or indirectly, more than 60 percent of,
respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Corporate Transaction (including, without limitation, a
corporation that as a result of such transaction owns the Company or all or
substantially all of the Company's assets either directly or through one or more
subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Corporate Transaction, of the Outstanding Company
Common Stock and the Outstanding Company Voting Securities, as the case may be,
(B) no Person (excluding any corporation resulting from such Corporate
Transaction or any employee benefit plan (or related trust) of the Company or
such corporation resulting from such Corporate Transaction) beneficially owns,
directly or indirectly, 20 percent or more of, respectively, the then
outstanding shares of common stock of the corporation resulting from such
Corporate Transaction or the combined voting power of the then outstanding
voting securities of such corporation except to the extent that such ownership
existed prior to the Corporate Transaction and (C) at least a majority of the
members of the board of directors of the corporation resulting from such
Corporate Transaction were members of the Incumbent Board at the time of the
execution of the initial agreement, or of the action of the Board, providing for
such Corporate Transaction; or

                           (iv)     Approval by the stockholders of the Company
of a complete liquidation or dissolution of the Company.

Anything in this Agreement to the contrary notwithstanding, if a Change of
Control occurs and if the Executive's employment with the Company is terminated
prior to the date on which the Change of Control occurs, and if it is reasonably
demonstrated by the Executive that such termination of employment (i) was at the
request of a third party who has taken steps reasonably calculated to effect a
Change of Control or (ii) otherwise arose in connection with or anticipation of
a Change of Control, then for all purposes of this Agreement the date upon which
the Change of Control occurred shall mean the date immediately prior to the date
of such termination of employment.
