RE:  Reserve Evaluation and
     Net Income Projection
     Farmers and Snyder Assets

Gentlemen:

     As an extension of the reserve  evaluation and cash flow projections I have
done for Comerica Bank-Texas,  you have requested additional economic runs using
your proprietary oil and gas price schedules.  With Comerica's permission to use
the data  base  and  projections  prepared  on their  behalf,  attached  are the
economic runs you requested.

     I have made  these  reserve  determinations  and cash flow  projections  in
conformance  with the  definitions  and  procedures  approved  by the Society of
Petroleum  Evaluation  Engineers.  The  projections  have been made  using  your
requested price and cost forecasts as follows:

     Oil:    $21.00/bbl plus or minus historical differentials for location and
             quality plus applicable bonuses through the life of the bonus 
             contract, escalating at 3% per year.

     Gas:    $2.25/mcf plus or minus historical differentials for location and
             quality, escalating at 3% per year.

     LOE:    Historical costs escalating at 3% per year.

     I have  independently  evaluated the subject reserves for Comerica Bank and
for Jay Resources and confirm that no employee of Riseden  Services,  Inc. has a
financial interest in the results of this evaluation.
