SECTION 3. Administration

     The Plan shall be administered by the Committee. The Committee shall have
sole and complete authority to adopt, alter and repeal such administrative

participation in the Plan is voluntary and only those persons that agree to
participate in the Plan will actually participate.

SECTION 5. Maximum Amount Available for Stock Grants

Grants may be made under the Plan shall be a total of Six Hundred Thousand
shares of Common Stock. Shares of Common Stock may be made available from the

equitable adjustment will be made in the number or kind of shares available for
grant.

SECTION 6. Stock Grants

     Subject to the provisions of the Plan and subject to compliance with
applicable securities and other laws, on the day that a salary, bonus, or
commission compensation payment is to be paid to the Participant, the Company,
at its discretion, shall grant to the Participant a number of shares of Common
Stock having a Fair Market Value, measured as of the business day immediately
preceding the day of the grant of the Common Stock, equal to 100% of the salary,
bonus, or commission compensation payable to the Participant for the relevant
period or situation. The Company may also, in its discretion, determine to grant
an additional number of shares of Common Stock to mitigate the market risk Plan
participants will be subject to and to cover brokerage commissions and other
incidental expenses that might be incurred by Plan participants in connection
with the sale of the Stock Grant shares. The Company shall not be required to
issue any fractional shares. Stock Grants under the Plan will be rounded up to
the nearest whole number.

     The Company will deposit the Stock Grant shares in a brokerage account in
the name of the Participant. The Participants will control the decision of
whether or not to sell the shares and the timing of such sales. The Participant
will promptly pay to the Company or a Subsidiary, as applicable, all Withheld
Amounts.

SECTION 7. General Provisions

     (a)  The Company and its Subsidiaries expressly reserve the right at any
time to terminate the employment of any Participant free from any liability, or
any claim under the Plan. Neither the Plan nor any Stock Grant is intended to
confer upon any Participant any rights with respect to continuance of employment
or other utilization of his or her services by the Company or by a Subsidiary,
nor to interfere in any way with his or her right or that of his or her employer
to terminate his or her employment or other services at any time (subject to the
terms of any applicable contract).

shall be determined solely in accordance with the laws of the State of Texas
(without giving effect to its conflicts of laws rules) and, to the extent
applicable, federal law.

Company's Shareholders.

shares of Common Stock pertaining to any Stock Grant upon any securities
exchange or under any federal or state law or the effecting or obtaining of any
consent or approval of any governmental body.

     (e)  The Board of Directors may amend, abandon, suspend or terminate the
Plan or any portion thereof at any time in such respects as it may deem
advisable in its sole discretion, provided that no amendment shall be made
without stockholder approval (including an increase in the maximum number of
shares of Common Stock in respect of which Stock Grants may be made under the
Plan) if such stockholder approval is necessary to comply with any tax or
regulatory requirement or self regulatory organization rules (e.g., NYSE, NASD),
including for these purposes any approval requirement that is a prerequisite for
exemptive relief under Section 16(b) of the Exchange Act.

     IN WITNESS WHEREOF, the Company has caused this Amended and Restated Plan
to be executed on its behalf as of October 15, 2003.
