Dear Ken:

This  LETTER  AGREEMENT  shall  set forth  the  terms  and  conditions  for your
participation  in the  RANKEN  ENERGY  CORPORATION  ("REC")  OWL CREEK  PROSPECT
located  in  Garvin & McClain  Counties,  Oklahoma.  Specifically,  you agree to
participate with a 70% Working Interest, subject to the following:

1).      You agree to purchase an undivided 70% Working  Interest in the REC OWL
         CREEK PROSPECT for a total Buy-In Cost of $211,750.00  ($302,500 x .70)
         which is your proportionate share.

2).      All future leasehold costs shall  be  billed  to  the  Joint Account at
         $350/acre at a 78% net revenue basis.

3).      Your initial Buy-In Cost includes all current  leasehold  (820.42 + net
         acres),  whether force pooled or leased,  in support of the two initial
         re-entry test wells,  geologic  expenses,  brokerage costs, 3-D seismic
         usage, geophysical interpretations, and overhead, etc.

4).      You agree to pay your  Buy-In  Cost upon the  execution  of this LETTER
         AGREEMENT,  as well as your proportionate  share of the estimated costs
         to casing point for:

                  DRILLING:                 JOHNSON #1 RE-ENTRY
                  DRILLING:                 POWELL #1 RE-ENTRY

5).      You agree to  participate in the  Drilling Operations (to casing point)
         in the wells as specified in Item #3 above, with your interest, bearing
         your  proportionate  share of a 20% carried Working  Interest in all of
         these  operations.  The carried  working  interest in these two initial
         Re-Entry  wells  shall be  defined  as  those  costs  incurred  for the
         drilling and  setting/cementing  of production casing. All future costs
         shall be billed to the Joint Account on a "heads up" basis. Your Before
         Casing Point  Interest "BCP" shall be 87.5% and your After Casing Point
         Interest "ACP" shall be 70%. This carried  Working  Interest shall only
         apply to the two initial  re-entry  test wells  listed in  paragraph #4
         above.  However,  should the primary  objective  (Viola) in each of the
         initial  Re-Entry  wells not be reached due to any down hole  problems,
         then you agree to drill a replacement  well or wells, on the same terms
         and obligations as set forth in this LETTER AGREEMENT.
