                                    AGREEMENT

     Termination  Because  of  Change  in  Control.  In the event of a Change in
          Control (as  hereinafter  defined)  of the  Company,  and  Employee is
          either not  employed  by the  acquiring  corporation  in a  comparable
          position at a comparable salary, then (i) the Company or the acquiring
          corporation, as the case may be, shall be obligated to pay to Employee

          several   payments  or   obligations   owed  to  Employee  under  such
          circumstances   and  shall   supersede  any   severance   payments  or
          obligation.

     This Agreement  in relation  to Stock Grant
          As a portion of the Employment Agreement the parties have entered into
          a Stock Grant Agreement.  The terms of the Stock Grant are intended to
          govern a share  exchange for a  Consolidation  or Merger.  Neither the
          Stock Grant or this Agreement are intended to be exclusive remedies in
          a Change of Control. It is not the parties intent that the Stock Grant
          limit this  Agreement  in any way, nor is this  Agreement  intended to
          limit the Stock Grant in any way.




          Paragraph  5(d) of the Stock  Grant is  included  below for  reference
     purposes only.

     (d)  Notice of  Consolidation  or  Merger  and Stock  Grant  Exchange.  The
          Company shall not, at any time after the date hereof, effect a merger,
          consolidation,  exchange of shares, recapitalization,  reorganization,
          or other  similar  event,  as a result of which shares of Common Stock
          shall be changed into the same or a different  number of shares of the
          same or  another  class or  classes  of stock or  securities  or other
          assets of the  Company or another  entity or there is a sale of all or
          substantially all the Company's assets (a "Corporate Change"),  unless
          the resulting  successor or acquiring entity (the "Resulting  Entity")
          assumes by written  instrument  the Company's  obligations  under this
          Stock Grant,  including but not limited to the Stock Grant Price reset
          provisions as provided  herein during the term of the resultant  Stock
          Grants,  and agrees in such written  instrument  that this Stock Grant
          shall be  exercisable  into such class and type of securities or other
          assets of the  Resulting  Entity as Holder  would  have  received  had
          Holder fully  Vested  under the terms of this Stock Grant  immediately
          prior to such  Corporate  Change,  and the Stock  Grant  Price of this
          Stock Grant shall be  proportionately  increased  (if this Stock Grant
          shall be  changed  into or become  exchangeable  for a Stock  Grant to
          purchase a smaller  number of shares of Common Stock of the  Resulting
          Entity) or shall be  proportionately  decreased  (if this Stock  Grant
          shall be changed or become  exchangeable for a Stock Grant to purchase
          a larger  number of shares of Common Stock of the  Resulting  Entity);
          provided,  however,  that Company may not affect any Corporate  Change
          unless it first  shall  have  given  three  (3) days  notice to Holder
          hereof of any Corporate Change.


     Excluded  Transaction.  The purposed  transactions set forth in Exhibit "A"
          are hereby  specifically  not to be deemed a Change of Control for the
          purposes of this Agreement.





    Applicable Law.

          This Change of Control Agreement shall for all purposes be governed by
     and construed in accordance with the laws of the state of Oklahoma, without
     giving effect to conflict of law provisions thereof.

     Control Agreement as of the 21st day of January 2003.
