  services are important to it and it therefor wishes to provide for the
  secure continued employment of the Employee and to formalize its agreements
  with the Employee on the scope of his duties, his compensation and the

                 NOW, THEREFORE, the Company agrees to employ the Employee,
  and the Employee agrees to be employed, upon the following terms and
  conditions:
  
       1.        The Company shall employ the Employee as Chief Executive
  Officer and Chairman of the Board for the Term (as hereinafter defined),

  assigned to him by the Board of Directors of the Company (the "Board"). 
  During the Term, the Employee shall devote substantially all of his
  attention, knowledge, skill and working time to the business of the Company
  and to the promotion of its interests (with the exception of absences
  because of vacations or illness).  During the Term, the Employee will not
  engage in, be employed by, be a director of (excluding service as a

  is not required to be at the Company's offices in Irving, Texas, each
  working day.
  
       2.        During the first year of the Term, the Company shall pay the
  Employee a base salary of $500,000 per year (payable periodically in
  accordance with the Company's regular payroll practices), subject to any
  required deductions or withholdings.  During the second year of the Term,
  Employee's base salary shall be increased, but not decreased, in the
  discretion of the Board, but not less than the percentage increase in the
  cost of living for the year 1996.
  
       3.        The Employee shall be entitled to such reasonable vacations
  during each year of his employment hereunder as may be allowed by the Board
  in accordance with its general practices applicable to the Company's senior
  executives.
  
       4.        The Company shall reimburse the Employee for all reasonable

  he incurs in the course of his duties during the Term.  Such reimbursable
  expenses shall include those incurred by Employee's spouse when she
  accompanies him on business travel.  The Company shall also provide a
  suitable automobile and driver for Employee's commute to and from the
  Company's offices and local business travel.

  termination of employment, (iii) the death of the Employee or (iv) the
  termination of his employment by the Company pursuant to Paragraph 6.
  
                (b)     In addition to the payment of Employee's salary
  pursuant to Paragraph 2, if the Employee's employment is terminated by the
  Company prior to the expiration of the Term, other than under circumstances
  described in Paragraph 6, or if Employee terminates his employment for good
  reason, as provided in Paragraph 7, Employee shall be entitled to a
  severance payment in accordance with the following schedule:
  
                Termination Occurring                    Amount of Payment

       6.       The Company may terminate the employment of the Employee at
  any time for "cause," which shall mean (i) the willful and continued failure
  by Employee to attempt to perform substantially his duties with the Company
  (other than such failure resulting from Employee's incapacity due to
  physical or mental illness), (ii) commission of a material willful breach of
  the terms of this Agreement, (iii) gross negligence or willful misconduct in
  the performance of assigned duties or (iv) conviction of a felony or other
  crime involving fraud or moral turpitude.  Any such termination shall occur
  only after at least 90 days' written notice by the Board of Directors of the
  Company to the Employee, which notice shall specifically identify the cause
  for termination and shall include, in any instance other than under clause
  (iv) above, a demand for cure by the Employee.  If Employee fails to
  eliminate the cause for termination within the 90-day period, his
  termination shall then be effective.
  
        7.       At any time during the Term, Employee shall be entitled to
  terminate his employment for "good reason" which for the purposes of this
  Agreement shall mean (i) a reduction or diminution of his position, titles,
  offices, duties, responsibilities or status with the Company without cause
  and without the Employee's express written consent, (ii) a reduction by the
  Company in the Employee's base salary in effect at the time in accordance
  with Paragraph 2 hereof, (iii) relocation of the Company's executive offices
  to a site outside Dallas County or Tarrant County, Texas or (iv) any other
  breach by the Company of its obligations under this Agreement, which the
  Company fails to cure within a reasonable period of time after receipt of
  written notice of such breach, which period is not to exceed 90 days unless
  agreed upon in writing by both parties.  Any amount owing to Employee in
  such case pursuant to Paragraph 5(b) shall be paid to Employee within 10
  business days following his termination of employment.
  
         8.       The Employee shall be entitled to participate in such
  insurance, pension, profit-sharing and other benefits as are or may become
  available generally to executive officers and/or other employees of the
  Company on a basis comparable to that of such other executive officers and
  employees of the Company to the extent permitted by applicable laws or
  governmental regulations.  Employee shall be entitled to participate in the
  Company's Stock Option Plan in accordance with the agreement entered into
  between Employee and the Company under that Plan.  Employee shall be
  entitled to participate in the Company's retiree medical program without
  regard to any length of service requirement.
  
         9.       The Employee shall be, and he represents that he is, free to
  enter into this Agreement with the Company, and not under any contractual
  restraint that would prohibit him from satisfactorily performing his duties
  to the Company hereunder.
  
       10.       This Agreement shall inure to the benefit of and shall bind
  all successors to the Company by merger, consolidation or sale of all or
  substantially all of the Company's present principal business.  This
  Agreement is personal to both parties and may not be assigned by either of
