Attention:  Mr. Dennis Hedke
            Acting President and CEO

Dear Mr. Hedke:

           As  requested,  we have made an estimate of the  reserves  and future
production and income  attributable to certain leasehold  interests of Diasu Oil
and Gas  (Diasu) as of October 1, 2000.  The proved  reserves  included  in this
report conform to the guidelines of the Society of Petroleum Engineers (SPE) and
the Society of Petroleum  Evaluation  Engineers  (SPEE).  The probable  reserves
conform to the  guidelines  of the SPE and SPEE.  This report has been  prepared
using  constant  prices and costs  provided by Trinity  Energy  Resources,  Inc.
(Trinity) and are detailed in this letter. The subject properties are located in
the  states of  Louisiana,  Texas and  Wyoming.  The  results  of this study are
summarized below:

Reserve Definitions

           The proved reserves included herein conform to the definitions as set
forth in the Securities and Exchange  Commission's  Regulation S-X Part 210.4-10
(a) as clarified by various  Commission  Staff  Accounting  Bulletins and to the
definitions endorsed by the Society of Petroleum Engineers (SPE) and the Society
of Petroleum  Evaluation  Engineers  (SPEE).  Definitions  of these reserves are
included immediately following this letter.

Estimate of Reserves

           Estimates  of reserves  were  prepared by the use of  geological  and
engineering methods generally accepted by the petroleum industry.  The method or
combination  of methods  utilized in the analysis of each reservoir was tempered
by experience in the area,  stages of development,  quality and  completeness of
basic data, and production history.

           Where applicable,  the volumetric method was employed for determining
the original  quantities of hydrocarbons in place.  Where sufficient  geological
data was  available,  structural  maps were prepared to delineate each reservoir
and isopachous maps were constructed to determine reservoir volumes.  Electrical
logs, core analysis, and other available data were used to prepare these maps as
well as to determine  representative  values for porosity and interstitial water
saturation. Reserves based upon volumetric calculations or other methods such as
analogy with offset  wells are usually  subject to greater  revision  than those
based upon production  and/or pressure  performance data.  Therefore,  it may be
necessary  to revise these  estimates up or down in the future as more  reliable
engineering data becomes available.

           Reserves of  depletion-type  reservoirs  or those  whose  performance
disclosed  reliable  decline  in  production-rate  trends  or  other  diagnostic
characteristics  were estimated by the application of appropriate decline curves
or other  performance  relationships.  In the  analysis  of  production  decline
curves, reserves were estimated only to a calculated economic limit.

Estimate of Future Producing Rates

           Initial  production  rates were based on the current  rates for those
reservoirs now on production. If no production decline trend was established,  a
decline  profile  analogous to similar  wells was used.  If a decline  trend was
established, this trend was used as the basis for estimating future rates.

Product Prices

           Liquid Prices

           Trinity provided the liquid  hydrocarbon  prices.  For the purpose of
this report, the prices were held constant over the life of the reserves with no
future  price  escalation.  The  resulting  overall  average  price  for oil and
condensate  reserves  is $23.00  per  barrel.  The oil and  condensate  reserves
account for 52.7 percent of the future gross income from all proved reserves.

           Gas Prices

           Trinity provided the gas prices.  For the purpose of this report, the
prices were held  constant  over the life of the  reserves  with no future price
escalation.  The resulting  overall  average price for gas reserves is $3.00 per
MCF. Gas  reserves  account for 47.3 percent of the future gross income from all
proved reserves.

Income Data

           The future gross revenue is determined before deduction of production
taxes.  Future net income is determined  after  deduction of the normal costs of
operating the wells,  recompletion  and development  costs. The operating costs,
recompletion  and  development  costs  were  held  constant  for the life of the
reserves with no future cost escalation due to inflation.  The future net income
is before the  deduction  for state and  federal  income  taxes and has not been
adjusted  for  outstanding  loans  which  may  exist.  It does not  include  any
adjustment for cash on hand or undistributed income.

           Table A  presents  a  summary  of the  8/8ths  reserves,  prices  and
interests for the subject properties by state, field and lease. Table B presents
a summary of net reserves and income data for the subject  properties  by state,
field and lease.  Table C presents  a summary  of the  proved net  reserves  and
income data ranked by discounted  future net income.  Tables 1 through 7 are the
grand  summaries and Tables 8 through 55 are the field  summaries and individual
well cash flow tables. A production decline curve for the producing  properties,
which  graphically  illustrates  past  hydrocarbon  production  history  and our
estimated projection of future production, follows at the end.

General

           The reserves  included in this report are  estimates  only and should
not be  construed  as being  exact  quantities.  They may or may not be actually
recovered and, if recovered, the revenues therefrom and the actual costs related
thereto  could  be  more  or  less  than  the  estimated  amounts.   Because  of
governmental  policies and uncertain ties of supply and demand, the actual sales
volumes and the prices received from the reserves, along with the costs incurred
in recovering such reserves,  may vary from those  assumptions  included in this
report.  Also,  estimates  of reserves  may  increase or decrease as a result of
future operations.

           We are qualified to perform engineering  evaluations and do not claim
expertise  in  accounting  or legal  matters.  As in all  aspects of oil and gas
evaluation,   there  are  uncertainties   inherent  in  the   interpretation  of
engineering data and therefore,  our conclusions  necessarily represent only our
best informed professional judgments.

           The titles to the  properties  have not been examined by R. A. Lenser
and  Associates,  Inc. nor has the actual degree or type of interest  owned been
independently  confirmed.  The data used in our  estimates  were  obtained  from
Trinity and were accepted as accurate.  For the purposes of this report, a field
inspection of the properties was not performed nor was the mechanical  operation
or condition of the wells and their  related  facilities  examined.  We have not
investigated  possible  environmental  liability  related to the properties and,
therefore,  our  estimates do not include any costs which may be incurred due to
such possible liability.

           We are independent petroleum engineers and geologists;  we do not own
an interest in these  properties  and are not  employed on a  contingent  basis.
Basic geologic and field  performance  data together with our  engineering  work
sheets are maintained on file in our office and are available for review.

                                               Very truly yours,
