      and liabilities, of whatever kind or nature, in law or in equity, of the
      Borrower, whether now known or unknown to the Borrower, which may have

      outlined above, and shall not be construed as an agreement to change any
      other terms or provisions of the Credit Agreement. This agreement shall
      not establish a course of dealing or be construed as evidence of any
      willingness on the Bank's part to grant other or future agreements, should
      any be requested.

            


    


    
      
         


      

      
         


        
          

        

      

      
         


      

    


    
      	
              8.

            	
              INTEGRATION, ENTIRE AGREEMENT,
      CHANGE, DISCHARGE, TERMINATION, OR WAIVER. The Credit Agreement, as
      modified by this agreement, and the other Related Documents contain the
      complete understanding and agreement of the Borrower and the Bank in
      respect of the Credit Facilities and supersede all prior understandings
      and negotiations. No provision of the Credit Agreement, as modified by
      this agreement, or the other Related Documents, may be changed,
      discharged, supplemented, terminated, or waived except in a writing signed
      by the party against whom it is being
enforced.

            


    

    


    
      	
              9.

            	
              Governing Law and Venue.
      This agreement shall be governed by and construed in accordance with the
      laws of the State of Texas (without giving effect to its laws of
      conflicts). The Borrower agrees that any legal action or proceeding with
      respect to any of its obligations under this agreement may be brought by
      the Bank in any state or federal court located in the State of Texas, as
      the Bank in its sole discretion may elect. By the execution and delivery
      of this agreement, the Borrower submits to and accepts, for itself and in
      respect of its property, generally and unconditionally, the non-exclusive
      jurisdiction of those courts. The Borrower waives any claim that the State
      of Texas is not a convenient forum or the proper venue for any such suit,
      action or proceeding.

            


    

    


    
      	
              10.

            	
              NOT A NOVATION. This
      agreement is a modification only and not a novation. Except as expressly
      modified by this agreement, the Credit Agreement, any other Related
      Documents, and all the terms and conditions thereof, shall be and remain
      in full force and effect with the changes herein deemed to be incorporated
      therein. This agreement is to be considered attached to the Credit
      Agreement and made a part thereof. This agreement shall not release or
      affect the liability of any guarantor of any promissory note or credit
      facility executed in reference to the Credit Agreement or release any
      owner of collateral granted as security for the Credit Agreement. The
      validity, priority and enforceability of the Credit Agreement shall not be
      impaired hereby. To the extent that any provision of this agreement
      conflicts with any term or condition set forth in the Credit Agreement, or
      any other Related Documents, the provisions of this agreement shall
      supersede and control. The Bank expressly reserves all rights against all
      parties to the Credit Agreement and the other Related
      Documents.

AGREEMENTS OF THE PARTIES.
