defined in Section  411(a)(13) of the Code or Section  206(d)(3) of the Employee
Retirement  Income Security Act of 1974, as amended),  provided that in the case

extent it will not result in  disqualifying  such option as an  incentive  stock
option under Section 422 of the Code, or any other successor provision.

     9.  Rights  as  Stockholder.  The  Option  Holder  will have no rights as a

     10.  Adjustment of Number of shares and Related Matters.  The Option Holder
understands  that in the  event of a stock  dividend,  stock  split,  change  of
control,  merger,  consolidation,  reorganization  or  recapitalization  of  the
Company, the number of shares which may be purchased upon exercise of this Stock
option, the time at which any Stock Option may be exercisable,  and the exercise
price thereof may be adjusted in accordance with the Plan.

     11. Option Holder's Representations.  Notwithstanding any of the provisions
hereof,  the Option  Holder  hereby  agrees that he or she will not exercise the
Stock Option granted hereby, and that the Company will not be obligated to issue
any  shares to the  Option  Holder  hereunder,  if the  exercise  thereof of the
issuance of such shares shall constitute a violation by the Option Holder or the
company of any provision or any law or regulation of any governmental  authority
or shall not be in compliance with the listing  requirements of a stock exchange
or an interdealer quotations system. Any determination in this connection by the
board shall be final, binding and conclusive. The obligations of the company and
the rights of the Option Holder are subject to all  applicable  laws,  rules and
regulations  including,   without  limitation,  the  1934  Act,  the  Code,  any
successors thereto, and any other applicable laws.

her in a transaction  registered under  applicable  federal and state securities
laws, by his or her execution hereof,  the Option Holder represents and warrants
to the Company that all Common Stock which may be  purchased  hereunder  will be
acquired by the Option Holder for investment purposes for his or her own account
and not with any intent for resale or  distribution  in  violation of federal or
estate  securities  laws.  Unless  the  Common  Stock  is  issued  to  him  in a
transaction  registered under applicable  federal and state securities laws, all
certificates  issued with respect to the Common Stock shall bear an  appropriate
restrictive investment legend.

     13. Disqualifying Disposition. In the event that Common Stock acquired upon
exercise  of a Stock  Option  pursuant  to this  Agreement  is disposed of by an
Option  Holder prior to the  expiration of either two (2) years from the Date of
Grant of such Stock  option or one (1) year from the  transfer  of shares to the
Option Holder pursuant to the exercise of such Stock option,  such Option Holder
shall notify the company in writing of the date and terms of such disposition.

     14.  Governing Law. This Agreement is intended to be performed in the State
of Texas and shall be construed and enforced in accordance  with and governed by
the laws of the  State of  Texas  without  reference  to the  conflicts  of laws
provisions thereof.

     15. No Rights to Continue  Employment.  Nothing in this  Agreement  confers
upon the Option Holder the right to continue in the employ of the company or any
subsidiary or  interferes  with or restricts in any way the right of the Company
to discharge the Option  Holder at any time  (subject to any contract  rights of
the Option Holder).

     16.  Invalidity of Provision.  The  invalidity or  unenforceability  of any
provision of this Agreement in any jurisdiction shall not affect the validity or
enforceability  of the remainder of this Agreement in that  jurisdiction  or the
validity or enforceability of this Agreement,  including that provision,  in any
other  jurisdiction.  If any  provision  of this  Agreement  shall  be  adjudged
unreasonable  in  any  judicial  or  administrative  proceeding,  the  court  or
administrative  body shall have the power to reform such  provision  and, in its
changed form, such provision shall then be enforceable and shall be enforced.

     In witness Whereof, the Company has caused this Agreement to be executed by
its duly  authorized  officer,  and the Option  Holder,  to evidence  his or her
consent and approval of all the terms hereof,  has duly executed this  Agreement

upon the Option Holder the right to continue in the employ of the company or any
subsidiary or  interferes  with or restricts in any way the right of the Company
to discharge the Option  Holder at any time  (subject to any contract  rights of
the Option Holder).

     16.  Invalidity of Provision.  The  invalidity or  unenforceability  of any
provision of this Agreement in any jurisdiction shall not affect the validity or
