         This Option will terminate and cease to be exercisable upon Employee's
termination of employment with the Company, except that:

                  (a) If Employee's employment with the Company terminates by
          reason of disability (within the meaning of section 22(e)(3) of the
          Code) or retirement, this Option may be exercised in full by Employee
          at any time during the period of one year following such termination,
          or by Employee's estate (or the person who acquires this Option by
          will or the laws of descent and distribution or otherwise by reason of
          the death of Employee) during a one year period following Employee's
          death if Employee dies during the one year period following such
          termination. As used in this paragraph, "retirement" shall mean the
          termination of Employee's employment with the Company for reasons
          other than cause (as defined in (c) below) on or after attainment of
          age 65 or, with the express written consent of the Committee, on or
          after the age of 55.

                  (b) If Employee dies while in the employ of the Company,
          Employee's estate, or the person who acquires this Option by will or
          the laws of descent and distribution or otherwise by reason of the
          death of Employee, may exercise this Option in full at any time during
          the period of one year following the date of Employee's death.

                  (c) If Employee's employment with the Company terminates for
          any reason other than as described in (a) or (b) above, unless such
          employment is terminated for cause, this Option may be exercised by
          Employee at any time during the period of three months following such
          termination, or by Employee's estate (or the person who acquires this
          Option by will or the laws of descent and distribution or otherwise by
          reason of the death of Employee) during a period of one year following
          Employee's death if Employee dies during such three-month period, but
          in each case only as to the number of shares Employee was entitled to
          purchase hereunder as of the date Employee's employment so terminates.
          As used in this paragraph, the term "cause" shall mean Employee (i)
          has been convicted of a misdemeanor involving moral turpitude or of a
          felony, (ii) has engaged in gross negligence or willful misconduct in
          the performance of the duties of Employee's employment, (iii) has
          willfully disregarded any written corporate policies established by
          the Company, or (iv) has materially breached any material provision of
          any written agreement between Employee and the Company or any of its
          Affiliates.

         This Option shall not be exercisable in any event after the expiration
of six years from the date of grant hereof. The purchase price of shares as to
which this Option is exercised shall be paid in full at the time of exercise (a)
in cash (including check, bank draft or money order payable to the order of the
Company), (b) by constructively tendering to the Company shares of Stock having
a fair market value equal to the purchase price and which shares, if acquired
pursuant to a Company granted option, have been held by Employee for more than
six months, (c) if the Stock is readily tradeable on a national securities
market, through a "cashless-broker" exercise in accordance with a
Company-established policy or program for the same, or (d) any combination of
the foregoing. No fraction of a share of Stock shall be issued by the Company
upon exercise of an Option or accepted by the Company in payment of the exercise
price thereof; rather, Employee shall provide a cash payment for such amount as
is necessary to affect the issuance and acceptance of only whole shares of
Stock. Unless and until a certificate or



                                       2

certificates representing such shares shall have been issued by the Company to
Employee, Employee (or the person permitted to exercise this Option in the event
of Employee's death) shall not be or have any of the rights or privileges of a
shareholder of the Company with respect to shares acquirable upon an exercise of
this Option.

         4. WITHHOLDING OF TAX. To the extent that the exercise of this Option
or the disposition of shares of Stock acquired by exercise of this Option
results in compensation income to Employee for federal or state income tax
purposes, Employee shall deliver to the Company at the time of such exercise or
disposition such amount of money or, with the consent of the Committee, shares
of Stock as the Company may require to meet its minimum withholding obligations
under applicable tax laws or regulations, provided that if, when the Option is
exercised, Employee is subject to Section 16(b) of the Securities Exchange Act
of 1934, as amended, by reason of being a current or former officer or director
of the Company or an Affiliate, Employee may direct the Company to withhold a
number of Option shares for the exercise sufficient to satisfy such minimum tax
withholding requirements. No exercise of this Option shall be effective until
Employee (or the person entitled to exercise the option, as applicable) has made
arrangements approved by the Company to satisfy all applicable minimum tax
withholding requirements of the Company.

         5. STATUS OF STOCK. The Company has registered for issuance under the
Securities Act of 1933, as amended (the "Act"), the shares of Stock acquirable
upon exercise of this Option, and intends to keep such registration effective
throughout the period this Option is exercisable. In the absence of such
effective registration or an available exemption from registration under the
Act, issuance of shares of Stock acquirable upon exercise of this Option will be
delayed until registration of such shares is effective or an exemption from
registration under the Act is available. The Company intends to use its
reasonable best efforts to ensure that no such delay will occur. In the event
exemption from registration under the Act is available upon an exercise of this
Option, Employee (or the person permitted to exercise this Option in the event
of Employee's death or incapacity), if requested by the Company to do so, will
execute and deliver to the Company in writing an agreement containing such
provisions as the Company may require to assure compliance with applicable
securities laws.

         Employee agrees that the shares of Stock which Employee may acquire by
exercising this Option will not be sold or otherwise disposed of in any manner
which would constitute a violation of any applicable securities laws, whether
federal or state. Employee also agrees (i) that the certificates representing
the shares of Stock purchased under this Option may bear such legend or legends
as the Committee deems appropriate in order to assure compliance with applicable
securities laws, and (ii) that the Company may refuse to register the transfer
of the shares of Stock purchased under this Option on the stock transfer records
of the Company if such proposed transfer would in the opinion of counsel
satisfactory to the Company constitute a violation of any applicable securities
laws and (iii) that the Company may give related instructions to its transfer
agent, if any, to stop registration of the transfer of the shares of Stock
purchased under this Option.

         6. EMPLOYMENT RELATIONSHIP. Employee shall be considered to be in the
employment of the Company as long as Employee remains an Employee, Director or
consultant of the Company or any of its Affiliates. Any question as to whether
and when there has been a termination of such employment, and the cause of such
termination, shall be determined by the Committee and its determination shall be
final.

         7. BINDING EFFECT. This Agreement shall be binding upon and inure to
the benefit of any successors to the Company and all persons lawfully claiming
under Employee.

         8. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Texas, without regard to conflicts of
law principles thereof.

executed by its officer thereunto duly authorized, and Employee has executed
this Agreement, all as of the day and year first above written.
