          2.   Representations by Superior.  Superior has the full and perfected
               right to issue to Foster the shares of common  stock of  Superior
               described in this Agreement.  In this regard, it has obtained the
               approval of its board of directors.

          3.   Purchase and Sale of the Properties.  Superior agrees to purchase
               from  Foster,  and  Foster  agrees  to  sell  to  Superior,   the
               Properties in  consideration of the issuance to Foster of 300,000
               newly-issued shares of common stock of Superior ("the Shares").

          4.   Warranty of Title to the  Properties.  Foster  warrants  that the
               title to the  Properties  is good and  marketable  and  agrees to
               defend such title at his own expense should it be challenged.

          5.   Closing.   The  parties   shall  close  the   Purchase  and  Sale
               transaction  described herein at a mutually agreeable time within
               one week from the date of this  Agreement or as otherwise  agreed
               to  between  the  parties.  Prior to the  Closing,  Foster  shall
               deliver to Superior copies of executed, acknowledged and recorded
               oil and gas leases or  assignments  of leases that  evidence  the
               title of Foster or his alter egos to the Properties and the right
               to transfer to Superior the Properties.

          6.   Applicable Law,  Arbitration and Sole Agreement.  The laws of the
               state of Kansas shall apply to all issues  regarding title to the
               Properties.  The  laws of  Oklahoma  shall  apply  to all  issues
               regarding the legal effect and meaning of the  provisions of this
               Agreement.  Disputes  between  the  parties  shall be resolved by
               binding arbitration  employing rules of the American  Arbitration
               Association or other rules agreed to by the parties.  This is the
               sole agreement between the parties relating to the Properties.

          7.   Restricted   Nature  of  the  Shares.   In  accordance  with  the
               regulations of the U.S.  Securities and Exchange Commission ("the
               Commission"),  the Shares will be "restricted  securities" within
               the  meaning  of the  Commission's  Rule  144.  As  such,  absent
               registration   or  the   availability   of  an   exemption   from
               registration,  they  cannot  be  transferred  for value by Foster
               during the first full year after the  Closing.  During the second
               year after the Closing they can be transferred  for value without
               registration  pursuant to the provisions of Rule 144. Thereafter,
               provided  Foster is not an affiliate of Superior and has not been
               as  affiliate  of  Superior  during the 90 days before a proposed
               transfer  for value,  Foster  can  transfer  the  Shares  without
               registration  and without  complying  with the provisions of Rule
               144.
