     ("RG-Desert")

     Rio Grande Offshore, Ltd.      Partnership         80%             100%
     ("Offshore")

     Rio Grande GulfMex, Ltd.       Partnership         N/A              80%
     ("GulfMex")

          Prior to February 1, 1996,  Drilling's  ownership  interest in the oil
          and gas  properties  acquired by Offshore was 80%.  Robert A. Buschman
          ("Buschman"),  H. Wayne  Hightower  and H. Wayne  Hightower,  Jr. (the
          "Hightowers")  owned the remaining  20%  interest.  As a result of the
          Company's 80% ownership interest, Offshore's financial statements were
          combined  with  the  Company's  financial  statements  prepared  as of
          January 31, 1996.

          Effective  February 1, 1996,  Buschman  and the  Hightowers  agreed to
          restructure  Offshore  whereby  the  aggregate  20%  minority  limited
          partnership   interests  of  Buschman  and  the  Hightowers  would  be
          redeemed,  and as a result of in kind distributions,  Buschman and the
          Hightowers became proportionate working interest owners of the onshore
          oil and gas  properties  previously  held by  Offshore.  All  existing
          interest in the oil and gas properties located offshore Louisiana held
          by Offshore at January 31, 1996, were conveyed to GulfMex, a newly

                                       -5-

          formed Texas  limited  partnership,  which has the same  proportionate
          ownership  structure as that of Offshore  prior to the  restructuring.
          Buschman and the Hightowers no longer are limited partners of Offshore
          and are now 20% limited partners in GulfMex. Subsequent to January 31,
          1996,  Offshore is 100% indirectly owned by the Company and GulfMex is
          80%  indirectly  owned  by  the  Company  which  is  reflected  in the
          condensed combined financial statements prepared subsequent to January
          31, 1996. The minority interests of Buschman and the Hightowers, prior
          to and after the restructure,  are set forth separately in the balance
          sheet and the statements of operations of the Company.

          All intercompany balances and transactions have been eliminated in the
          combined condensed financial statements.

          In  the  opinion  of  management,  the  condensed  combined  financial
          statements  reflect all  adjustments  which are  necessary  for a fair
          presentation  of the  financial  position  and results of  operations.
          Adjustments  made for the  nine  months  ended  October  31,  1996 are
          considered normal and recurring in nature.

          The Company  utilizes the successful  efforts method of accounting for
          its oil and gas properties.  Under this method,  the acquisition costs
          of  oil  and  gas  properties   acquired  with  proven   reserves  are
          capitalized  and  amortized  on  the   unit-of-production   method  as
          produced.  Development  costs or exploratory costs are capitalized and
          amortized  on the  unit-of-production  method if proved  reserves  are
          discovered, or expensed if the well is a dry hole.

          Earnings  per share  computations  are based on the  weighted  average
          number of shares and  dilutive  common stock  equivalents  outstanding
          during the respective  periods.  Fully dilutive  earnings per share is
          the same as earnings per common and common equivalent shares.

(2)       Acquisition of Oil and Gas Properties

          On March 11, 1996,  Offshore acquired a 3.125% leasehold interest in a
          non-operated  producing federal oil and gas lease and platform ("Block
          76") located offshore  Louisiana for approximately  $932,000.  On July
          30,  1996,  Offshore  acquired  an  additional  leasehold  interest of
          1.041667%  in Block 76 for  $270,000.  Effective  with that  purchase,
          Offshore's total leasehold interest in Block 76 is equal to 4.16667%.

          On March 26, 1996,  Offshore acquired leasehold interests in three gas
          wells  located in Wheeler  County,  Texas for a net purchase  price of
          approximately $370,500. The total net proved reserves acquired by this
          acquisition were 3,000 bbls oil and condensate and 868,000 mcf gas.
          Drilling operates these gas wells.

          On April 12, 1996, Offshore acquired various leasehold interests in 31
          oil  wells  located  in   Mississippi   and  Louisiana   ("Mississippi
          Properties")  for a net purchase  price of  approximately  $2,800,000,
          which includes 23 wells to be operated by Drilling.  Due to the timing
          of closing the acquisition,  the March 1996 revenues and related lease
          operating  expenses  have  been  recorded  as  an  adjustment  to  the
          acquisition price.

Item 1.  FINANCIAL STATEMENTS (continued)

(3)      Long-Term Debt

          On March 8, 1996, the Company  executed a loan agreement with Comerica
          Bank - Texas  ("Comerica") which provides a new senior credit facility
          ("Senior Credit  Facility") in an aggregate  principal amount of up to
          $10,000,000,  with an initial  borrowing  facility of $4,967,000  (the
          "Borrowing  Base").  The Senior Credit  Facility was used to refinance
          the Company's  existing senior  indebtedness of $1,575,000 and provide
          $900,000 to purchase the 3.125% working  interest in Block 76 on March
          11, 1996.

          On March 26, 1996, the Company acquired various leasehold interests in
          three gas wells  located in Wheeler  County,  Texas for a net purchase
          price of approximately  $370,500, of which approximately  $320,500 was
          financed with Comerica.

          Comerica   financed   approximately   $1,100,000  of  the  approximate
          $2,800,000  acquisition  price of the Mississippi  Properties on April
          12, 1996. Approximately,  $300,000 was funded from working capital for
          the closing on April 12,  1996.  By  agreement  with the  seller,  the
          remaining  balance  of  approximately  $1,405,000  was  financed  by a
          seller's note ("Sellers Note") due with interest on August 30, 1996.

          Under terms of the Senior Credit Facility,  the Borrowing Base will be
          redetermined  by the lender  each year on  February  1, or sooner,  if
          requested  by the  Company.  In August  1996,  the  Company  requested
          Comerica to increase  the  Borrowing  Base to  facilitate  funding the
          Sellers Note due on August 30, 1996. On August 30, 1996,  Comerica and
          the Company agreed to increase the Borrowing  Base to $5,350,000.  The
          Borrowing  Base is determined by the lender,  in its sole  discretion,
          using  procedures and standards  customary for its petroleum  industry
          customers,  and  represents  the  amount  of  borrowings  which in the
          lender's opinion the Company's oil and gas properties will support. On
          August 30, 1996, the Sellers Note of approximately $1,451,000 was paid
          with $1,200,000 of additional  financing from Comerica and $251,000 of
          the Company's  working capital.  As of October 31, 1996, the Company's
          outstanding balance under the Senior Credit Facility is $5,275,000.

          Under the terms of the Senior  Credit  Facility,  the initial  monthly
          reductions to the Borrowing  Base of $82,000  commenced  April 1, 1996
          and continued to August 1, 1996. On August 30, 1996, Comerica adjusted
          the monthly  reductions to the  Borrowing  Base to $75,000 to commence
          October 1, 1996 through February 1, 1997. Beginning March 1, 1997, the
          Borrowing  Base will be  subject  to monthly  reductions  of  $110,000
          through  January 1, 1998.  When the  outstanding  principal  under the
          Senior Credit  Facility  exceeds the Borrowing  Base, the Company must
          make principal payments to reduce the outstanding  balance equal to or
          less then the  Borrowing  Base.  On  February  1,  1998,  which is the
          maturity  date of the  Senior  Credit  Facility,  the  principal  then
          outstanding shall be due and payable.  The interest rate to be charged
          on the outstanding principal balance is based on Comerica's prime rate
          plus 1%.  All of the  Company's  interests  (direct  or  indirect)  in
          existing oil and gas properties,  miscellaneous assets, and future oil
          and gas property  acquisitions will serve as collateral for the credit
          facility.  The Senior Credit Facility  contains  various  restrictions
          including,  but not limited to,  restrictions on payments of dividends
          or  distributions  other than those capital  distributions to Buschman
          and  the  Hightowers  in  GulfMex,  maintenance  of  positive  working
          capital,  and no change in the majority ownership or current President
          of the Company.

          Comerica's  commitment to provide the Company a Senior Credit Facility
          required that the Company obtain certain  modifications and amendments
          from the holders ("Holders") of the 11.50% Subordinated

                                       -7-
<PAGE>


          Notes (the "Notes") dated  September 27, 1995 before the Comerica loan
          agreement  could be  concluded.  Such  consents  and  amendments  were
          approved by the Holders on March 8, 1996.  The repayment  terms of the
          Notes were amended to provide for a final  maturity on  September  30,
          2002 (instead of September 30, 2000) and the quarterly amortization of
          principal  over four years,  commencing  in December  1998,  at annual
          rates of  12.5%,  12.5%,  37.5% and  37.5% of the  original  principal
          amount  (instead  of  amortization  of  principal  over  three  years,
          commencing in December  1997, at annual rates of 12.5%,  37.5% and 50%
          of the original principal amount).


Item 2.   MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND
          RESULTS OF OPERATIONS.

                  1.       Material Changes in Financial Condition.

                           The Company's financial condition for the nine months
                           ended October 31, 1996 has changed significantly from
                           the fiscal year ended January 31, 1996 as a result of
                           three  major  acquisitions  of  various  oil  and gas
                           properties,  the restructuring of subordinated  debt,
                           and the  execution  and  the  funding  of a new  loan
                           agreement   with   Comerica   which   increased   the
                           outstanding debt of the Company as described herein.

                  2.       Material Changes in Results of Operations.

                           Oil and Gas Production Segment

                           For the  quarter and nine  months  ended  October 31,
                           1996,  revenues  from  oil  and gas  production  were
                           approximately      $1,340,000     and     $3,733,000,
                           respectively, as compared to $777,000 and $2,706,000,
                           respectively,  for the quarter and nine months  ended
                           October 31, 1995.  Production  operating expenses for
                           the quarter and nine  months  ended  October 31, 1996
                           were    approximately    $683,000   and   $1,830,000,
                           respectively, as compared to the production operating
                           expenses of $472,000  and  $1,458,000,  respectively,
                           for the  quarter and nine  months  ended  October 31,
                           1995.  The  increase in revenues is due  primarily to
                           additional   revenues  of  approximately   $1,223,000
                           earned as the  result  of the oil and gas  properties
                           acquired  in March and April  1996.  The  increase in
                           production   operating   expenses   is   due  to  the
                           additional   properties  acquired  during  the  first
                           quarter of 1996 but was  partially  offset by reduced
                           production operating expenses on existing properties.

                           The Company utilizes the successful efforts method of
                           accounting   for  its   oil   and   gas   properties.
                           Amortization expenses for the quarter and nine months
                           ended    October    31,    1996    based    on    the
                           unit-of-production method were approximately $270,000
                           and  $721,000,  respectively,  for 498 and 1,354 MMCF
                           equivalent units of production. Amortization expenses
                           for the  quarter and nine  months  ended  October 31,
                           1995,  were  approximately   $312,000  and  $957,000,
                           respectively,  for 407  and  1,374,  MMCF  equivalent
                           units of production.

                           Interest  expense  for the  quarter  and nine  months
                           ended October 31, 1996 was approximately $222,000 and
                           $489,000,  respectively.  Interest  expense  for  the
                           quarter  and nine months  ended  October 31, 1995 was
                           approximately $71,000 and $214,000, respectively. For
                           the  quarter and the nine  months  ended  October 31,
                           1996,  interest expense increased due to the addition
                           of  bank  debt  of   approximately   $1,200,000   and
                           $3,775,000,  respectively,  which  was  used  for the
                           acquisition of oil and gas properties, the $1,405,000
                           Sellers Note executed in April 1996, and the issuance
                           in September 1995 of approximately $2,000,000, 11.50%
                           subordinated  notes to finance a development  program
                           on certain oil and gas  properties  located in Texas.
                           The  average  interest  rate  incurred on senior debt
                           during the quarter and nine months ended  October 31,
                           1996   was    approximately    10.25%   and   10.18%,
                           respectively.

                           During the quarter and nine months ended  October 31,
                           1996,  Offshore sold various producing  properties in
                           Montana and Texas with proceeds totaling $451,000 and
                           gain on sale of assets of $183,000.

                           For  the  nine  months   ended   October  31,   1996,
                           distributions to limited partners of $132,000 reflect
                           only GulfMex's operations.  For the nine months ended
                           October 31, 1995,  distributions  to limited partners
                           of $420,000 reflect Offshore's operations of offshore
                           and onshore properties held by the partnership before
                           the restructuring in February 1996.

                           Recent Operating Developments

                           Operations

                           The  Company  operates  a number  of wells in the KWB
                           Field  in  West   Texas,   in  which   Offshore   has
                           approximately  80%  of  the  working  interest.   The
                           Company   initiated   a  pilot   secondary   recovery
                           waterflood  project in that field by drilling a pilot
                           development    well   and   converting    surrounding
                           production   wells  to  water  injection  wells.  The
                           waterflood  pilot  test  was  initially   delayed  in
                           December  1995  but  the  water  injection  has  been
                           proceeding   since  January  1996.  While  the  water
                           injection  wells are causing a build-up in  reservoir
                           pressure,  no  material  additional  incremental  oil
                           production   has  been   experienced   in  the  pilot
                           development   well  since  the  well  was   initially
                           drilled.

                           The  Company  expected  that it would  take  from six
                           months to one year before any noticeable  increase in
                           secondary  recovery  production,  if  any,  would  be
                           realized.  If the waterflood pilot proves successful,
                           the projected number of additional  development wells
                           drilled would be 29 with projected  development costs
                           to the  Company  of  approximately  $5,800,000  and a
                           projected  increase in reserves of 1,100,000  bbls of
                           oil equivalent.  Should the waterflood pilot prove to
                           be uneconomical, the Company would likely abandon the
                           field.  The  Company  anticipates  that  the  sale of
                           salvageable   equipment  would  exceed  plugging  and
                           abandonment  expense for the existing  production and
                           water  injection  wells.  The  Company  has  expended
                           approximately  $303,000  to date  for  the KWB  pilot
                           waterflood.

                           The Company  attempted  reworking  three gas wells in
                           Wheeler County, Texas during 1996 by recompleting the
                           wells  in  the  Granite  Wash  production  intervals.
                           Although drilling logs and information  gathered from
                           adjacent gas wells which produced in the same horizon
                           indicated  good  production  potential,  the  Company
                           encountered  unexpected  conditions  in the  wellbore
                           which  caused an incursion  of water.  The  Company's
                           effort to remedy the water  incursion in the targeted
                           production intervals proved unsuccessful.  Two of the
                           gas wells are producing  from the Granite  Wash,  but
                           the production is marginally economical.  The Company
                           expended  approximately $336,000 for the workover and
                           completion   efforts   of  these   wells,   of  which
                           approximately $134,000 was expensed as dry hole costs
                           in the current fiscal year.

                           On  April  30,  1996,  production  from  Block 76 was
                           suspended  due to mechanical  problems  incurred with
                           the  production  equipment.  In late June  1996,  the
                           operator  of Block 76 began a major  workover  to the
                           well which was successfully completed


<PAGE>



                           in mid-July 1996. The total cost for the workover was
                           budgeted at approximately  $1.6 million,  however the
                           actual  workover  cost  incurred  was   approximately
                           $2,520,000   of  which   the   Company's   share  was
                           approximately  $84,000.  Production from Block 76 has
                           been restored to the level of production prior to the
                           shut-in.

                           Liquidity and Capital Resources

                           In March 1996, the Company  entered into a commitment
                           letter  with a new  lender to replace  the  Company's
                           then  existing  bank  indebtedness  of  approximately
                           $1,575,000.  The commitment  letter required that the
                           Company obtain certain  modifications  and amendments
                           from the Holders before the new credit facility could
                           be  concluded.  Such  consents  and  amendments  were
                           approved by the Holders on March 8, 1996. As amended,
                           the Notes  provide for a final  maturity on September
                           30, 2002  (instead  of  September  30,  2000) and the
                           quarterly  amortization of principal over four years,
                           commencing  in  December  1998,  at  annual  rates of
                           12.5%,   12.5%,  37.5%  and  37.5%  of  the  original
                           principal   amount   (instead  of   amortization   of
                           principal  over three years,  commencing  in December
                           1997, at annual rates of 12.5%,  37.5% and 50% of the
                           original  principal  amount).  In  addition  to other
                           provisions   amended,   the  exercise  price  of  the
                           warrants  granted was reduced  from $.40 per share to
                           $.20 per share.

                           The Company's new Senior Credit Facility provides for
                           up  to   $10,000,000   in   borrowings,   subject  to
                           limitations  on  availability  as  a  result  of  the
                           Borrowing Base determination. Under the Senior Credit
                           Facility,  the  initial  borrowing  base  ("Borrowing
                           Base") was  $4,967,000.  The  Borrowing  Base will be
                           redetermined by the lender each year on February 1 or
                           sooner,  if specially  requested by the Company.  The
                           Borrowing  Base is an  amount  as  determined  by the
                           lender, at its sole discretion,  using procedures and
                           standards   customary  for  its  petroleum   industry
                           customers,  as the amount which the Company's oil and
                           gas  properties  will support the  principal  balance
                           outstanding  under the  Senior  Credit  Facility.  In
                           August 1996, the Company requested an increase of the
                           Borrowing  Base.   Effective  August  30,  1996,  the
                           Borrowing Base was increased to  $5,350,000.  Initial
                           proceeds  from  the  Borrowing   Base  were  used  to
                           refinance the Company's existing senior  indebtedness
                           of $1,575,000 on March 11, 1996 and provide  $900,000
                           to  purchase a 3.125%  working  interest  in Block 76
                           located offshore Louisiana.  The Block 76 acquisition
                           increased  the  Company's  net proved gas reserves by
                           927,000  mcf.  Block 76 consists of only one offshore
                           well and therefore  presents a greater degree of risk
                           than the acquisition of multiple properties.

                           On  March  26,  1996,   Offshore  acquired  leasehold
                           interests  in three  gas  wells  located  in  Wheeler
                           County,   Texas   for  a  net   purchase   price   of
                           approximately  $370,500.  Funds of $320,500  from the
                           Borrowing  Base and working  capital of $50,000  were
                           used by the Company to make the  acquisition of these
                           wells. The total net proved reserves acquired by this
                           acquisition  were 3,000 bbls oil and  condensate  and
                           868,000 mcf gas. Drilling operates these gas wells.

                           On April 12, 1996,  Offshore acquired the Mississippi
                           Properties,  which  includes  23  wells  operated  by
                           Drilling,  for an acquisition  price of approximately
                           $2,800,000.  The total net proved  reserves  acquired
                           were 725,000 bbls oil and condensate. At closing, the
                           Company  funded  half of the  acquisition  price with
                           approximately


<PAGE>



                           $1,100,000 from the Borrowing Base and  approximately
                           $300,000 of working  capital.  By agreement  with the
                           seller,  the remaining half of the acquisition  price
                           of  approximately  $1,405,000  was  financed  by  the
                           Sellers Note payable with interest at prime which was
                           paid in full on August 30, 1996.

                           On July 31,  1996,  Offshore  acquired an  additional
                           1.041667%  working  interest in Block 76 for $270,000
                           which  was  financed  by  Comerica.  This  additional
                           working  interest  increased the Company's net proved
                           gas reserves by approximately 300,000 mcf.

                           Under  the  terms  of  the  Senior  Credit  Facility,
                           monthly  reductions to the Borrowing  Base of $82,000
                           commenced April 1, 1996 and continued  through August
                           1, 1996.  Beginning  October 1, 1996 through February
                           1,  1997,  the  Borrowing  Base is subject to monthly
                           reductions of $75,000.  Beginning  March 1, 1997, the
                           Borrowing Base will be subject to monthly  reductions
                           of  $110,000   through  January  1,  1998.  When  the
                           outstanding   principal   under  the  Senior   Credit
                           Facility exceeds the Borrowing Base, the Company must
                           make  principal  payments  to reduce the  outstanding
                           balance equal to or less then the Borrowing  Base. On
                           February 1, 1998,  which is the maturity  date of the
                           Senior  Credit  Facility,  the  principal  debt  then
                           outstanding  shall be due and  payable.  The interest
                           rate  to be  charged  on  the  outstanding  principal
                           balance is based on the lender's  prime rate plus 1%.
                           All of the Company's  interests (direct and indirect)
                           in  existing  oil and gas  properties,  miscellaneous
                           assets, and future oil and gas property  acquisitions
                           serve as collateral  for the Senior Credit  Facility.
                           The   Senior   Credit   Facility   contains   various
                           restrictions   including,   but   not   limited   to,
                           restrictions    on   payments   of    dividends    or
                           distributions  other than  capital  distributions  to
                           Buschman and the  Hightowers in GulfMex,  maintenance
                           of  positive  working  capital,  and no change in the
                           majority ownership or the President of the Company.

                           RECENT DEVELOPMENTS

                           Louisiana  Acquisition.  Offshore executed a purchase
                           and  sale  agreement  on  November  20,  1996  with a
                           Louisiana   corporation   for  the   acquisition   of
                           producing  oil and gas  properties  in the  Righthand
                           Creek  Field  ("Righthand  Creek")  located  in Allen
                           Parish,   Louisiana.   The  effective   date  of  the
                           Righthand Creek  acquisition is November 1, 1996 with
                           the closing  anticipated to occur on or about January
                           16,  1997,  subject to  customary  due  diligence  by
                           Offshore.  The  Company  has  deposited  $250,000  as
                           earnest  money which is subject to  forfeiture to the
                           sellers if the  acquisition  is not  concluded  on or
                           before  January 16, 1997. The  acquisition  price for
                           Righthand  Creek is  approximately  $15  million  for
                           total proved  producing  reserves of  approximately 2
                           million  barrels of oil and 2 Bcf  natural gas net to
                           Offshore's  interest.  Drilling  will be the operator
                           for the  seven  wells  currently  producing  from the
                           Wilcox formation.

                           The  purchase  and  sale   agreement   provides  that
                           Offshore will conduct certain drilling  operations on
                           undeveloped  leasehold  acreage  within  twelve  (12)
                           months of the closing  date.  Offshore  must commence
                           the spud-in of two (2) wells within  twelve months of
                           closing  to  test  the  Wilcox  "B"  Sand,   however,
                           Offshore does have the option to re-enter an existing
                           well located on the  undeveloped  acreage which would
                           count as one well. In the event that  Offshore  fails
                           to drill either of the  required  wells to the Wilcox
                           "B"  formation,  the  seller has the right to require
                           

<PAGE>



                           Offshore  to convey to the seller a working  interest
                           in the unearned acreage.

                           In connection with Offshore's  requirement to develop
                           the undeveloped leasehold acreage, the seller has the
                           option to obtain a working  interest  ranging from 10
                           to 20 percent in all wells  completed  effective upon
                           Offshore obtaining project payout. Project payout for
                           the wells  completed  by  Offshore  as defined by the
                           purchase and sale agreement would occur when Offshore
                           has received proceeds from the wells drilled equal to
                           all   actual   costs   of    drilling,    completing,
                           re-completing,  equipping, maintaining, producing and
                           operating the wells drilled.  The sellers'  option to
                           obtain such working  interest  would remain in effect
                           until  the  sellers  have  recovered   proceeds  from
                           production  sales net of revocable costs and expenses
                           proportionate  to their working interest in the wells
                           drilled.   The  working  interests  obtained  by  the
                           sellers  as  described  above  would  revert  back to
                           Offshore  at  such  time  that  the  sum of  the  net
                           proceeds received by the sellers equals $7 million.

                           In  connection  with  the  proposed  Righthand  Creek
                           acquisition,  the Company has  obtained a  commitment
                           from Comerica to increase the Senior Credit  Facility
                           from $10 million to $25 million  which would  provide
                           for  an  increase  in  the   Borrowing   Base  up  to
                           approximately  $17 million.  The $12 million increase
                           in  Borrowing  Base would be subject to a loan fee of
                           $75,000.  The  interest  rate  to be  charged  on the
                           outstanding  principal  balance would be based on the
                           lender's   prime  rate  plus  1/2%.   The  commitment
                           provides for monthly reductions in the Borrowing Base
                           of approximately $330,000 effective April, 1997.

                           Comerica's  commitment  to increase the Senior Credit
                           Facility and Borrowing  Base is  contingent  upon the
                           successful  placement  and  funding  of at least  $10
                           million of additional equity in the Company.

                           Proposed Private Placement.

                            The Company has engaged Reid Securities  Corporation
                           ("Reid") as its exclusive agent to assist the Company
                           in effectuating the sales of equity in the Company by
                           means   of   private   placement   to   institutional
                           investors. The Company will pay Reid a fee equal to 2
                           1/2%  of  the  aggregate  proceeds  received  by  the
                           Company through any such private placement.

                           Recently the Company entered into a nonbinding letter
                           of  intent  with  an   unrelated   third  party  (the
                           "Investor")   introduced   to  the  Company  by  Reid
                           providing  for the  purchase  by the  Investor  of an
                           aggregate  of $10 million in newly  issued  preferred
                           stock of the Company.  The  preferred  stock would be
                           issued in two $5 million  series,  one of which would
                           pay a cumulative dividend of 15% per annum and one of
                           which would pay a cumulative cash or in-kind dividend
                           of  14%  and  be   convertible   into  common   stock
                           representing   approximately  24%  of  the  Company's
                           outstanding  common stock on a fully  diluted  basis,
                           assuming   exercise  of  all  currently   outstanding
                           warrants  and  options.  One series of the  preferred
                           stock would be mandatorily  redeemable by the Company
                           upon the occurrence of certain events, and the entire
                           issuance would be redeemable in certain circumstances
                           at the  option  of the  Investor.  In  addition,  the
                           preferred   stock  would  have  the  right  to  elect
                           one-third of the  Company's  directors.  The proposed
                           transaction   is  subject  to  a   satisfactory   due
                           diligence   review,   negotiation  and  execution  of
                           


<PAGE>


                           mutually   satisfactory   definitive   documentation,
                           approval of the final terms by the Company's Board of
                           Directors  and  the  Investor,  consummation  of  the
                           Righthand  Creek  acquisition,  and  other  customary
                           conditions.  The Company  expects to use the proceeds
                           of the  preferred  stock  transaction  to  provide  a
                           portion of the  acquisition  price of Righthand Creek
                           and to reduce  indebtedness,  including prepayment of
                           the Company's $2 million 11.5% Subordinated Notes due
                           2002.

                           Expected  Closings.  Management expects the Righthand
                           Creek acquisition, the Comerica restructuring and the
                           preferred   stock   transaction   to  be  consummated
                           contemporaneously  in early January. In the event the
                           preferred stock  transaction is not consummated,  the
                           Company  would  owe  certain   breakup  fees  to  the
                           Investor  which could  aggregate up to $100,000.  The
                           Company would  promptly seek  alternative  sources of
                           equity or debt  financing in order to consummate  the
                           Righthand   Creek   acquisition  and  effectuate  the
                           Comerica restructuring. While management believes the
                           currently proposed  transactions will be successfully
                           concluded,   no  assurance  can  be  given  that  the
                           preferred  stock  transaction  will  be  successfully
                           concluded   or  that   if  it  is  not   successfully
                           concluded,  alternative  debt or equity  financing to
                           permit    consummation   of   the   Righthand   Creek
                           acquisition will be available.

RIO GRANDE, INC.
10101 Reunion Place, Suite 210
San Antonio, TX 78216-4156

Attention:        Guy Bob Buschman President

Gentlemen:

 In connection with the proposed issue and sale (by means of a private placement
to institutional investors) by Rio Grande, Inc. (the "Company") of approximately
$10 to $15 million of subordinated  debt,  preferred stock or any other security
issued by the  Company  (the  "Securities"),  the  Company  and Reid  Securities
Corporation ("Reid") agree:

 1.  (a)  Prior  to the  sale of the  Securities  to any  prospective  purchaser
("Offeree"),  the authorized employees of the Company shall: (i) furnish or make
available  to each  Offeree and any person  advising  such  Offeree all relevant
information  pertaining  to the  Company  and the  Securities  and the terms and
conditions of the offering,  and (ii) give each Offeree and any person  advising
such Offeree the opportunity to ask questions and receive answers concerning the
Company and the Securities and the terms and conditions of the offering.

 (b) To the best of the  Company's  knowledge  all written  information  or oral
information  provided  to  Offerees or to Reid by  authorized  employees  of the
Company  will not contain  any untrue  statement  of a material  fact or omit to
state a material fact necessary to make such information not misleading.

 (c) The Company covenants that it shall promptly advise Reid if, because of the
occurrence of any event or condition, the passing of time or otherwise,  written
information or oral  communications of the Company and its employees to Offerees
which  relate  to the  offer  and  sale of the  Securities  contain  any  untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements,  in light of the  circumstances  under which they were made, not
misleading,  and the written  information  (and attendant  oral  communications)
shall be amended in form and substance satisfactory to Reid so that after giving
effect  to  such  amendment,   the  written   information  (and  attendant  oral
communications) will not contain any untrue statement of a material fact or omit
to state a material fact necessary to make the  statements,  in the light of the
circumstances under which they were made, not misleading.

 2. The Company hereby  appoints Reid as its exclusive  agent to effect sales of
the Securities on a best efforts basis during the period  commencing on the date
of this engagement letter and ending December 31, 1996 (the 'Offering  Period"),
which may be mutually  extended  by written  agreement  of the  parties  hereto.
Subject  to the terms  and  conditions  herein  set  forth,  Reid  accepts  such
appointment  and shall use its best  efforts to find  purchasers  for all of the
Securities.  Reid's  agency  hereunder  is coupled  with an interest  and is not
terminable by the Company without Reid's permission;  such agency shall continue
until the termination of the Offering Period,  except that if subscriptions  for
all of the  Securities  are received  prior to the  termination  of the Offering
Period,  Reid's  agency  shall  terminate  at the date of the  last  sale of the
Securities.  In the  event the  offering  of the  Securities  is  commenced  and
subscriptions  for the  Securities  are not  received by the end of the Offering
Period,  Reid's  agency  and this  Agreement  shall  terminate  without  further
obligation of either Reid or the Company to the other except as provided in this
paragraph 2 and in  paragraphs  4, 6 and 7. The Company  shall have the right to
reject any and all  proposed  purchasers  of the  Securities  for any reason the
Company deems reasonable.  Notwithstanding the foregoing, in the event that Reid
contacts an Offeree and  introduces the Offeree to the Company and its employees
and the Offeree  purchases the  Securities  from the Company within 1 year after
the expiration of the Offering Period,  Reid shall be entitled to the same sales
commission  provided  for in  paragraph 5 hereof with  respect to such  purchase
which would have been due had the purchase occurred during the Offering Period.

3. (a) The Company shall not,  directly or  indirectly  (except  through  Reid),
offer or sell,  or  attempt to offer or sell,  or  solicit  any offer to buy the
Securities.  As used in this  Agreement  the terms "offer" and "sale" shall have
the meanings specified in Section 2(3) of the Securities Act of 1933.

     (b) The Company and Reid shall approve in advance,  and if requested by the
Company,  shall have its counsel  review in  advance:  (i) every form of letter,
memorandum,  circular,  notice  or other  written  information  provided  to the
Offerees;  and (ii)  each  person  to whom  each  written  information  is to be
addressed or delivered.  Neither Reid nor the Company shall offer any Securities
for sale to, or solicit any offer to purchase any  Securities  from,  any person
that has not  previously  been  approved  for such  purpose by both Reid and the
Company.  The Company  and Reid shall  promptly  review all written  information
submitted by the other for approval,  and they shall use their  respective  best
efforts  promptly  to prepare  all written  information  reasonably  required in
connection with the offer and sale of the Securities.

 4. The Company will  reimburse  Reid on a monthly basis as incurred by Reid and
billed  to the  Company  for all costs and  other  expenses  relating  to Reid's
offering of the Securities, including without limitation all direct expenses for
travel and all other reasonable and necessary costs and expenses associated with
the offering and sale of the  Securities.  In the event the  Securities  are not
sold, the Company shall reimburse Reid for the costs and expenses incurred by it
as described in the foregoing sentence.

 5. As  compensation  for its services the Company  shall pay to Reid a cash fee
equal to 2 1/2% of the aggregate  proceeds received by the Company from the sale
of the  Securities.  Such fee shall be  contingent  upon the  consummation  of a
sale(s) and payable to Reid promptly following the closing thereof. In the event
that the transactions  contemplated by this agreement are not consummated by the
end of the Offering Period, the Company shall pay Reid a cash fee of $25,000.

 6. In  addition to the  amounts  which the Company has herein  agreed to pay to
Reid, the Company shall indemnify and hold Reid (and its directors, officers and
employees) harmless against any losses,  claims, damages or liabilities to which
Reid may become subject in connection with the transactions  contemplated hereby
and  shall  reimburse  Reid or such  person  for any  legal  or  other  expenses
reasonably incurred in connection with investigating,  settling or defending any
action or claim in  connection  therewith;  provided  however,  that the Company
shall not be liable in any such case to the extent  that any such  loss,  claim,
damage  or  liability  is found  in a final  judgment  of a court  of  competent
jurisdiction to have resulted from a breach of Reid's obligations to the Company
in connection  with the  performance by Reid of the services  pursuant hereto or
from Reid's gross negligence or willful misfeasance in performing such services.

 7. The indemnity  agreement contained in paragraph 6 shall remain operative and
in full force and effect  regardless of any  termination of this Agreement or of
any investigation made by or on behalf of the Company or Reid, and shall survive
the delivery of and payment for the Securities for a period of one year.

 8. This Agreement is made solely for the benefit of Reid, the Company and their
respective  successors and permitted assigns,  and no other person shall acquire
or have any right by  virtue of this  Agreement,  and the term  'successors  and
permitted  assigns" as used  herein  shall not  include  any  purchasers  of the
Securities.

                    Buyer's obligation to commence actual

                    drilling  operations (i.e.,  "spudding-in") of the following
                    "Prescribed  Wells" and prosecute the drilling  thereof with
                    all reasonable  care and diligence are,  together,  material
                    and moving  consideration  in favor of Seller  without which
                    consideration  Seller  would  not  have  entered  into  this
                    Agreement to sell the Undeveloped Assets.

               (b)  Schedule and Manner of Drilling of Prescribed Wells.  Within
                    the twelve (12) month period following Closing, Seller shall
                    commence the drilling  ("spudding-in")  of two (2) wells and
                    drill such wells with all due care and  diligence to a depth
                    sufficient  to test the  Wilcox  "B"  Sand,  as such sand is
                    found in other wells  producing  within the said U WX RD SU.
                    In the event that Buyer experiences  mechanical or equipment
                    failures or  unforseen  downhole  conditions  or  encounters
                    heaving shale or other impenetrable formation which preclude
                    or make  further  operations  unjustified,  Seller may cease
                    such  operations  and still satisfy the  requirement of this
                    provision by commencing  the drilling  ("spudding-in")  on a
                    substitute  well within ninety (90) days and  continuing the
                    drilling  thereof in same manner  required  of the  original
                    well or wells, and, in like manner, continue the prosecution
                    of such wells or  substitutes  therefor until the prescribed
                    drilling obligation has been satisfied.

                    In lieu of the requirement to drill one of the two wells, as
                    specified above, Buyer shall have the option to re-enter and
                    attempt the testing of the Wilcox "B" Sand, as found between
                    the depths of 11,032  feet and 11,102  feet on the  electric
                    log in the  existing  Magnolia-Ragley  No. 1 Well located in
                    Section 29, T5S,R7W, Allen Parish,  Louisiana. If attempted,
                    such  operation  shall be commenced  within said twelve (12)
                    month  period and  conducted  by Buyer with all due care and
                    diligence  to test the  Wilcox "B" Sand as found in the said
                    well  or a  sidetrack  thereof.  In the  event  that  due to
                    mechanical  or  equipment   failures  or  adverse   downhole
                    conditions which make the re-entry  operation or a sidetrack
                    operation  unjustified  and the  objective  of  testing  the
                    Wilcox "B" Sand is not met,  Buyer may cease such  operation
                    and still satisfy the drilling requirement of this provision
                    by commencing drilling operations ("spudding-in") on another
                    well within ninety (90) days of such cessation of operations
                    and continuing  such  operations in the same manner required
                    hereinabove. For purposes of this provision, commencement of
                    re-entry operations shall mean that point in time when a rig
                    capable of conducting  such  re-entry  operation is moved on
                    the  location of said  Magnolia-  Ragley No. 1 Well and such
                    re-entry  operation  is  prosecuted  with  all due  care and
                    diligence.

               (c)  In the event Buyer fails to drill the two prescribed  wells,
                    as set forth in subparagraph (b) above, then as its sole and
                    exclusive  remedy for such  failure,  each Seller shall have
                    the  right  to  obtain  reassignment  of  its  proportionate
                    working interest in the "Unearned Acreage," being all of the
                    Undeveloped  Assets  assigned to Buyer,  save and except the
                    acreage  assigned to any  drilling or  proration  unit for a
                    well drilled or recompleted by Buyer.  If at the end of such
                    12 month period for drilling the prescribed wells, the Buyer
                    has not spudded-in such two wells or if Buyer fails to drill
                    either of such  wells or  substitute  wells to the  required
                    depth,  then each  Seller  shall  have the option to provide
                    written  notice  to Buyer to  reconvey  to such  Seller  its
                    proportionate  undivided  interest  in all  of the  Unearned
                    Acreage.  Such  written  notice  must be  received  by Buyer
                    within 545 days after the date of this  Agreement  or within
                    100  days  after  Buyer  ceases  the   continuous   drilling
                    operations set forth in subparagraph  (b), above,  whichever
                    is later,  or such right to a  reassignment  shall be waived
                    and be of no  further  force and  effect.  Within 30 days of
                    receiving  notice,  Buyer  shall  deliver to each Seller who
                    properly and timely  requests a  reassignment,  an executed,
                    recordable    Assignment     reassigning    such    Seller's
                    proportionate working interest in the Unearned Acreage.

               (d)  In the event any lease within the Undeveloped  Assets is due
                    to expire  due to the  failure  of Buyer to drill  wells and
                    extend the primary term thereof and if Buyer does not choose
                    to pay delay  rentals or to extend or renew  such  leases or
                    obtain new leases on such  acreage,  then Buyer shall notify
                    Seller  accordingly  at least  sixty  (60) days prior to the
                    date such delay  rental is due or such lease is scheduled to
                    expire.  If Seller  requests in writing that Buyer  reassign
                    such lease,  Buyer shall promptly  reassign to Seller all of
                    Buyer's  right,  title and  interest in such  lease.  In the
                    event  Buyer  elects to extend or renew any  expiring  lease
                    within  the  Undeveloped  Assets  or  obtains  a  new  lease
                    covering the same lands within  twelve (12) months after the
                    date such lease  expires,  the  rights of Seller  under this
                    Paragraph 2.03 shall continue in effect for such  extension,
                    renewal or new lease.

               (e)  Seller's  Option  to  Assume  Interest.   Each  Seller,   as
                    identified on Exhibit "A," attached  hereto,  shall have the
                    same  separate  and  independent  option to assume each such
                    Seller's proportionate share of an undivided

                    (i)  twenty (20%)  working  interest in all wells drilled or
                         recompleted on the Undeveloped  Assets exclusive of the
                         Ballard Well,  included above as a Developed Asset, and
                         further  exclusive of that  portion of the  Undeveloped
                         Assets located  within the surface  boundaries of the U
                         WX RB SUA created by Louisiana  Office of  Conservation
                         Order No. 1041-C; and,

                    (ii) ten (10%) percent working interest in all wells drilled
                         or  recompleted  on  the  Undeveloped  Assets  situated
                         within  the  surface  boundaries  of  said U WX RB SUA,
                         excluding said Ballard Well; provided,  however, in the
                         event  that  said  U  WX  RB  SUA  is  revised  or,  if
                         terminated,  replaced by a new unit of a  configuration
                         that, by unit survey,  would include within its surface
                         boundaries  additional  acreage which is not subject to
                         the terms of any farmout described in Exhibit "B," such
                         additional  included acreage shall, for the purposes of
                         this  Agreement,  be  deemed  Undeveloped  Assets  and,
                         accordingly,  Seller's  working  interest  as  to  such
                         included acreage shall be twenty (20%) percent.

                    such option to become effective upon "Project Payout" and to
                    continue  in effect  until  each such  electing  Seller  has
                    received  such  Seller's  proportionate  share  of  the  7MM
                    Payout, defined below, attributable to such working interest
                    as set forth below.  The "Project  Payout"  shall occur when
                    Buyer has received from the proceeds of production  from the
                    wells  on the  Undeveloped  Acreage,  a sum  equal to all of
                    Buyer's  Recoverable  Costs and Expenses  incurred  prior to
                    date Project  Payout first occurs.  Buyer shall provide each
                    Seller  with  quarterly  statements  showing  the  status of
                    Project Payout,  and upon attaining  Project  Payout,  Buyer
                    shall promptly provide each Seller with written notification
                    thereof,  via  certified  mail,  and each Seller  shall have
                    thirty (30) days after receipt of such written  notification
                    within  which to notify Buyer of such  Seller's  election to
                    assume such proportionate share of an undivided twenty (20%)
                    working  interest  in such  wells.  Failure  of a Seller  to
                    notify Buyer of such election  shall  constitute an election
                    not be  assume  such  Seller's  proportionate  share of said
                    working  interest.  Recoverable  Costs  and  Expenses  shall
                    include   all   actual   costs  of   drilling,   completing,
                    re-completing, equipping, maintaining, connecting, producing
                    and operating the wells located on the  Undeveloped  Assets,
                    specifically   including   the  actual  costs  to  Buyer  of
                    conducting  and   interpreting  a  3-D  seismic   reasonably
                    necessary to evaluate the Assets,  should Buyer conduct such
                    seismic survey, as well as all ad valorem taxes burdening

                    the working  interests and all severance  taxes,  production
                    taxes,  royalties and overriding royalties,  in existence on
                    the date of Closing and  described on said Exhibit "B" which
                    burden or are chargeable to such interests or the production
                    of proceeds  therefrom.  Operating costs shall be determined
                    as set  forth in that  certain  currently  applicable  Joint
                    Operating  Agreement ("JOA"),  dated January 20, 1993 by and
                    between  Brechtel  Energy  Corporation,  Operator,  and Team
                    America, et al,  Non-Operator;  provided,  however,  that at
                    Closing Rio Grande  Drilling  Company shall become  Operator
                    under such JOA, and Buyer shall be included as an additional
                    party.  However,  with respect to this Article  2.03(e),  no
                    non-consent  penalties  shall be included in the Recoverable
                    Costs and Expenses.  After the occurrence of Project Payout,
                    the each party's  proportionate  undivided  working interest
                    shall be  subject  to such JOA,  including  the  non-consent
                    penalties on a well by well basis.  Each  electing  Seller's
                    proportionate  share  of such  20%  working  interest  shall
                    automatically revert to Buyer on the date when such electing
                    Seller has recovered  from the proceeds of production  sales
                    derived from the subject  wells (net of revocable  costs and
                    expenses paid by such Seller after  Project  Payout) of such
                    Seller's  proportionate  share of the sum of  Seven  Million
                    Dollars  ($7,000,000.00) (the "7MM Payout"). If any electing
                    Seller should make a non-consent  election for any operation
                    under  the JOA,  neither  the  proceeds  nor the  costs  and
                    expenses associated with the applicable  non-consent penalty
                    shall be applied  toward  the 7MM  Payout for such  Seller's
                    interest.

               f.   Prescribed Wells - Additional Covenants. With respect to any
                    well drilled  pursuant to the  provisions of this  Paragraph
                    2.03, the Buyer and Seller further agree that:

                    (a)  Should  Buyer  sell any or all of its  interest  in the
                         Assets prior to the  occurrence of the 7MM Payout,  the
                         provisions  of this  Paragraph  2.03  shall  become  an
                         obligation  running  with the land and shall  remain an
                         obligation of, and  encumbrance  upon, the interests of
                         each subsequent Assignee. Until such 7MM Payout occurs,
                         Rio Grande Drilling Company,  or an affiliate  thereof,
                         shall  remain as  Operator of the  Undeveloped  Assets;
                         provided,   however,   that  another   company  may  be
                         substituted as Operator, with Seller's written consent,
                         which shall not be unreasonably withheld.  Should Buyer
                         sell any or all of its interest in the Assets after the
                         occurrence of Project Payout, Buyer agrees to use
                         its best  efforts  to gain for  Seller  the  option  of
                         Seller  to  sell  its   interest   in  the   Assets  in
                         conjunction with Buyer's sale.

                    (b)  With  respect  to  any  well  drilled  pursuant  to the
                         provisions  of  this  Article  2.03  prior  to  Project
                         Payout,  as to which Buyer elects not to set production
                         casing,  the  Operator  shall  provide each Seller with
                         notice of such  election,  as provided in the JOA,  and
                         each  Seller  shall have a period of  forty-eight  (48)
                         hours after receipt of such written notification within
                         which  to elect to make a  completion  attempt  on such
                         well at those  electing  Sellers'  sole cost,  risk and
                         expense  pursuant to the  provisions of Article VI.6 of
                         the JOA, as modified by this subparagraph. Likewise, if
                         Seller's  completion  attempt is  unsuccessful,  Seller
                         shall also plug and abandon such well at Seller's  sole
                         cost, risk and expense.  If Seller's completion attempt
                         results in a well capable of  producing  in  commercial
                         quantities,  Seller  shall be  entitled  to receive all
                         proceeds  derived from the sale of all production  from
                         said  well  until  Seller  has  recovered,  out of such
                         proceeds,  three  hundred  (300%)  percent  of  all  of
                         Seller's  costs and expenses of  drilling,  completing,
                         equipping and operating said well to point of "payout."
                         At payout, Buyer shall have the right to assume a fifty

                         (50%)percent   working   interest   in  such  well  and
                         thereafter all costs and benefits  attributable  to the
                         working interest in such well shall be shared:  Seller,
                         fifty (50%) percent and Buyer fifty (50%) percent,  and
                         all  subsequent   operations  on  such  well  shall  be
                         governed by the JOA.  Any  proceeds  received  from the
                         sale of  production  derived from any well  operated by

                         election  following  Project Payout shall be applicable
                         to  the  Buyer's  fifty  (50%)   percent   reversionary
                         interest in any well  completed  by Seller  pursuant to
                         this  article;   (ii)  Buyer's  actual  costs  paid  in
                         connection with Buyer's  working  interest in such well
                         shall be included in the calculation of Project Payout;
                         and  (iii)  the  proceeds  derived  from  the  sale  of
                         production  attributable  to that  portion  of  Buyer's
                         working  interest  in such well  which is  acquired  by
                         Seller after Project Payout occurs (up to 10% of 8/8ths
                         thereof)  shall be included in the  calculation  of the

          Agreement,  Buyer and Seller  shall enter into an Escrow  Agreement in
          substantially  the form attached  hereto as Exhibit "D" but including,
          among its other terms and  conditions,  the following  procedures  for
          instructing the Escrow Agent to distribute the escrow funds:

          (a)  In the event  Closing  does  occur,  the  Escrow  Agent  shall be
               authorized to immediately  transfer all Escrow Funds, less escrow
               expenses but plus all interest accruing thereon,  from the Escrow
               Account into an account  designated,  in writing,  by Seller. The
               Escrow  Agent's   authority   shall  be  represented  by  written
               instructions  conveyed to Escrow Agent by facsimile  transmission
               from Buyer on Closing date.

          (b)  In the event  Closing does not occur and such failure to Close is
               not as a result of any of the exceptions to non-refundability set
               out in 2.01(b),  infra,  Buyer shall  instruct  Escrow Agent,  in
               writing  by  facsimile  transmission,  to  immediately  pay to an
               account designated by Brechtel Energy Corporation,  as Agent, the

          (c)  In the event  that  Closing  does not occur and such  failure  to
               close is a  result  of the  occurrence  of any one or more of the
               exceptions to  non-refundability  set forth in subparagraph  (b),
               Seller shall  promptly  instruct the Escrow Agent to  immediately
               pay the Escrow Fund to Buyer, plus all interest accruing thereto.

          (d)  In the event of the  occurrence  of  either of the  circumstances
               described in subparagraphs  (b) and (c) and the party required to
               provide  notice to the  Escrow  Agent  fails to do so,  the party
               entitled to the distribution of funds from the Escrow Account may
               provide the Escrow Agent with a sworn affidavit  attesting to the
               particular  circumstances  whereupon the Escrow Agent,  after the
               expiration  of five (5) days  written  notice  given to the other
               party,  shall promptly  release the escrow funds to the attesting
               party.

<PAGE>



          Price allocated to such singular Developed Asset identified on Exhibit
          "B-1",  increased  or decreased in the manner  described  herein.  Any
          adjustments  to  the  Closing   Purchase   Price,   other  than  those
          adjustments provided for in Article V, Title Matters, shall be applied
          on a pro rata basis to the Allocated  Value for all Developed  Assets.
          After  such  adjustments  are made,  any  adjustments  to the  Closing
          Purchase  Price  made  pursuant  to  Article V shall be applied to the
          Allocated Value for the particular Developed Asset(s) affected.

                    measured by, the  ownership of the Assets or the  production
                    of hydrocarbons or the receipt of proceeds  therefrom,  paid
                    by, or on behalf of, Seller in connection with the operation
                    of  the  Assets,  in  accordance  with  generally   accepted
                    accounting  principles and the JOA and  attributable  to the
                    period after the  Effective  Date until  Closing,  expressly

               (3)  with  respect  to the  interest  in the Assets  conveyed  to
                    Buyer, an amount equal to all prepaid expenses  attributable

                    are,  in  accordance  with  generally  accepted   accounting
                    principles and the JOA, attributable to the period after the
                    Effective  Date,  including,  without  limitation,   prepaid

               (4)  with  respect  to the  interest  in the Assets  conveyed  to
                    Buyer,  by  the  value  of  each  one-percent  (or  fraction
                    thereof) of increase in net revenue  interest  ("NRI") above
                    that set forth in Exhibit "B," attached  hereto,  such value
                    to be calculated by dividing the applicable  Allocated Value
                    by the NRI set forth in said Exhibit "B" and multiplying the
                    result thereof by the increase in NRI.

    (b)       With respect to the interest in the Assets conveyed to Buyer,  the
              Closing Purchase Price shall be adjusted downward as follows:

                    (1)  the  aggregate  amount of  proceeds  received by Seller

                         way  attributable  to the Assets  between the Effective
                         Date and Closing  (using  actual  sales,  not  Seller's
                         entitlement,  where such sales are greater than or less
                         than Seller's entitlement);

                    (2)  the  aggregate  amount of royalty  payments  payable to
                         third  parties  but held in  suspense  by  Seller as of
                         Closing;

                    (3)  the  amount of all  payments  made as  provided  for in
                         Article 2.02(a)(i), infra; and

                    (4)  by the value of each one-percent (or fraction  thereof)
                         of decrease in net revenue  interest ("NRI") above that
                         set forth in Exhibit "B," attached  hereto,  such value
                         to be calculated by dividing the  applicable  Allocated
                         Value of a well by the NRI set  forth  in said  Exhibit
                         "B" for such well and multiplying the result thereof by
                         the decrease in NRI.

               The adjustment described in Article 2.06(a)(2)and (3) shall serve
               to satisfy up to the amount of the adjustment, Buyer's obligation

               the adjustments  described in Article  2.06(a)(1)  shall serve to
               provide Buyer, up to the amount of the adjustment, with the value
               of the oil, gas and other  minerals and the proceeds and products
               from the Assets to which Buyer is entitled  between the Effective
               Date and Closing, and Buyer shall not have any separate rights to
               receive the production, proceeds and products affected.

               Buyer  and  Seller   shall   execute  and  deliver  a  settlement
               statement,   prepared  in  accordance  with  this  Agreement  and
               generally   accepted   accounting   principles   and   JOA   (the
               "Preliminary  Settlement  Statement"),  prepared  by Seller  that
               shall  set  forth  the   Preliminary   Purchase  Price  and  each
               adjustment  and  the  calculation  of  such  adjustment  used  to
               determine  such  amount.  Seller  shall  provide  Buyer  with the
               Preliminary  Settlement  Statement  not less than  three (3) days
               prior to  Closing  for  Buyer's  review  and  approval.  The term
               "Preliminary  Purchase  Price"  shall  mean the  Purchase  Price,
               adjusted  as  approved  by the parties and as provided in Article
               2.06,  using for such  adjustments  actual  costs,  except  where
               unavailable,  whereupon  Seller will use estimates of such costs.
               The  Preliminary  Settlement  Statement  shall also  contain wire
               transfer instructions  concerning the delivery of the Preliminary
               Purchase Price at Closing.

          of the  percentage  interest  in the  Assets  conveyed  to Buyer,  all
          proceeds  from  production,  accounts  receivable,  income  and  other
          revenues  with  respect to the Assets  which are  attributable,  under

          to the  Effective  Date shall  belong to Seller,  and those  which are
          attributable,  under generally accepted accounting principles and JOA,

                    currently  being paid  directly to Seller or its  authorized

                    to  respond  to a  release  or  discharge  of any  toxic  or

               (20) There  are  no  outstanding  unpaid  AFE's  respecting  work
                    conducted  upon the  Assets  for which  Buyer  could be held

                    materials  incidental  to, or occurring in connection  with,
                    such operations and that physical changes in the land and/or
                    water bottoms may have occurred as a result of such uses and

               (3)  Buyer  represents  that it is not otherwise  prevented  from
                    having  the Assets  transferred  to Buyer,  and its  General

                    public   records  and  Seller's   files  for  all  purposes,
                    including,  without limitation, for the purpose of detecting
                    the  presence  and   concentration  of   naturally-occurring
                    radioactive   materials   ("NORM")   and  asbestos  and  has
                    satisfied itself as to the physical  condition and potential
                    environmental  condition  of the  Assets,  both  surface and
                    sub-surface. Buyer acknowledges that no representations have
                    been made by Seller  regarding  environmental  conditions or

                    producing  oil  and gas or  other  valuable  minerals  as an

                    knowledgeable  in the evaluation and  acquisition of oil and
                    gas  properties.  Furthermore,  Buyer has been informed that
                    the  solicitations  of offers  and the sale of the Assets by

                    commission,  state or federal, and Buyer hereby specifically
                    agrees that neither Buyer nor its  directors,  shareholders,
                    employees,  representatives  or agents  shall  initiate  any
                    proceeding  based upon the  assertion or claim that the sale
                    contemplated hereunder is the sale of a security.

               (6)  Buyer  is  acquiring  the  Assets  for its own  benefit  and
                    account and not with the intent of selling  such Assets in a
                    manner that would be subject to regulation  under federal or

                                      E-24

<PAGE>



          during normal  business hours for  examination by Buyer.  Seller shall
          not be  obligated  to  perform  any  additional  title  work,  and any
          additional  abstracts  and title  opinions will not be made current by
          Seller.

               NO WARRANTY  OF ANY KIND IS MADE BY SELLER AS TO THE  INFORMATION
               SO SUPPLIED,  EXCEPT THAT ANY SUCH  DOCUMENTS  PROVIDED BY SELLER
               ARE  TRUE  AND  CORRECT  COPIES  OF  MATERIALS  PROVIDED  OR MADE
               AVAILABLE.  BUYER  AGREES THAT ANY  CONCLUSIONS  DRAWN  THEREFROM
               SHALL BE THE RESULT OF ITS OWN INDEPENDENT REVIEW AND JUDGMENT.

     5.02 Title Defect Defined.  The term "Title Defect", as used herein,  shall
          mean any encumbrance,  defect in or objection to Seller's title to the
          Assets  which,  alone or in  combination  with  other  defects,  would
          unreasonably  interfere  with  Buyer's  enjoyment of the Assets to the
          extent that Buyer would not have the same degree of  enjoyment  of the
          Assets as did Seller  immediately  prior to  Closing or which  impairs
          Seller's  special and limited  warranty of title or which results in a
          reduction of the NRI or WI decimals set forth on Exhibit "B."

     5.03 Notice of and Remedies for Title Defect.

          (a)  Upon  discovery of a Title Defect,  Buyer shall  promptly  notify
               Seller  in  writing  of the  nature of the  Title  Defect,  shall
               furnish Seller with Buyer's basis for the assertion of such Title
               Defect and data in support  thereof and shall furnish Seller with
               the proposed reduction in the Purchase Price attributable to such
               Title Defect,  and, in the event that the Buyer's estimate of the
               effects of such Title  Defect(s)  would cause a reduction  in the
               Purchase  Price in an amount in excess of twenty  (20%)  percent,
               advise  Seller,  subject to Seller's right to cure such defect(s)
               prior to Closing, of Buyer's decision to terminate this Agreement
               in accordance  with the  provisions  of Article  10.01(b) of this
               Agreement.

          (b)  Upon receipt of such notice,  Seller,  at its  discretion,  shall
               have the right to choose one of the following options:

               (1)  to cure  the  Title  Defect  at  Seller's  expense  prior to
                    Closing  thereby  eliminating  the need for a  reduction  in
                    Purchase Price; or

               (2)  to reduce the Purchase  Price by an amount  mutually  agreed
                    upon; or

               (3)  exclude the affected  Asset(s)  from the sale and reduce the
                    Purchase  Price  by an  amount  equal  to the  value  of the
                    excluded Asset(s) as set forth on Exhibit "B."

          (c)  Any Title Defect which is not  disclosed to Seller by Buyer on or
               before  December 31, 1996 shall  conclusively be deemed waived by
               Buyer for all purposes.

     5.04 If a Title  Defect is based upon  Buyer's  notice  that  Seller owns a
          lesser interest or the notice is from Seller to the effect that Seller
          owns a greater  interest  than  that  shown on  Exhibit  "B," then the
          Purchase Price shall be reduced or increased,  as  appropriate,  based
          upon  the  amount  allocated  to the  affected  Asset on  Exhibit  "B"
          attached  hereto.  In the event of a Title Defect which Seller,  after
          notification  as  hereinbelow  provided,  elects  not to cure prior to
          Closing,  or cannot cure prior to  Closing,  and which would cause the
          reduction  of the Purchase  Price by more than twenty  (20%)  percent,
          then either Seller or Buyer may

                                      E-25

<PAGE>



          terminate  this  Agreement  without any  liability  whatsoever  to the
          other,  and the Performance  Deposit,  as provided for in Article 2.02
          shall be refunded to Buyer in accordance with the Escrow Agreement.

                                       VI.
                            ENVIRONMENTAL CONDITIONS

     6.01 Buyer's Access to Assets.  Buyer and its employees and representatives
          shall, subject to any necessary third party approvals,  and at Buyer's
          sole risk and expense, be given access to all facilities,  properties,
          personnel,  books, records and other pertinent  information within the
          possession of Seller relating to the operation of the Assets.  Buyer's
          investigation  shall be  conducted  in a  manner  that  minimizes  any
          interference  with the  normal  operation  of the  Assets.  Buyer  may
          photocopy  information  that it  reviews  at  Buyer's  expense.  Buyer
          further and  specifically  waives any cause of action against  Seller,
          its directors,  shareholders,  employees,  representatives  and agents
          based upon a claim for damages,  losses,  costs,  expenses (including,
          attorneys' fees and court costs) arising out of,  resulting from or on
          account of, Buyer's  investigation of the  environmental  condition of
          the Assets prior to Closing. Neither Buyer nor agents, representatives
          or  consultants  of Buyer shall conduct any  environmental  testing or
          sampling on, or with respect to, the Assets prior to Closing,  without
          the prior written consent of Seller. Any information obtained by Buyer
          under this  Article 6.01 shall  remain  confidential  and shall not be
          disclosed,   except  to  Seller  and  Buyer's  agents,   partners  and
          consultants,  without Seller's prior written consent,  unless required
          pursuant to order of a court or governmental  agency exercising proper
          jurisdiction  over the Assets and the  environmental  matters relating
          thereto.

     6.02 Notice   of  and   Remedies   for   Material   Adverse   Environmental
          Condition(s).  Upon  discovery  of a  Material  Adverse  Environmental
          Condition(s) (being a condition which (1) is required to be remediated
          under  applicable  environmental  laws in effect on the Effective Date
          and (2) the cost to remediate  said  condition to lawfully  acceptable
          levels  together with the cost to remediate all such  conditions  will
          cost in total in excess of ten (10%) percent of the Purchase Price for
          the Buyer's share of such remediation costs and (3) said condition, or
          the severity thereof,  was not previously known, or made known, to the
          Buyer prior to execution of this Agreement),  Buyer shall  immediately
          notify  Seller in writing of the  nature of such  condition  and shall
          furnish Seller with Buyer's basis for the assertion of same along with
          data in support thereof.  In the event the Buyer has properly notified
          Seller  of  one or  more  environmental  conditions  which,  alone  or
          together,  constitute  a  Material  Adverse  Environmental  Condition,
          Seller  shall  select  one  of  the  following  options  at  its  sole
          discretion:

          (i)  agree to remedy the Material Adverse  Environmental  Condition(s)
               at its own  expense  prior to  Closing  or as soon as  thereafter
               practicable; or

          (ii) reduce the Purchase Price by an amount mutually agreed upon; or

          (iii)exclude the affected Assets from the sale and reduce the Purchase
               Price by an amount  equal to the value of the  Assets as shown on
               Exhibit "B-1"; or

          (iv) Seller may indemnify Buyer for the Material Adverse Environmental
               Condition, and the Purchase Price shall not be reduced; or

          (v)  Seller   may   terminate    this    Agreement;    provided   that
               notwithstanding the foregoing, in the event that Buyer's share of
               the cost of remediating a Material Adverse Environmental

                                      E-26

<PAGE>



               Condition will exceed twenty (20%) percent of the Purchase Price,
               Buyer shall have the option to terminate this  Agreement  without
               further liability, and the Performance Deposit shall be refunded.

               Any  Material  Adverse  Environmental   Condition  which  is  not
               disclosed by Buyer to Seller on or before December 31, 1996 shall
               conclusively be deemed waived by Buyer for all purposes.

               Notification  to Seller by Buyer of the  presence in the wellbore
               of naturally occurring  radioactive material ("NORM") or asbestos
               shall not be cause to  invoke  any of the  remedies  set forth in
               this Article 6.02.

     6.03 BUYER'S  RELEASE AND  INDEMNITY.  BUYER HEREBY  RELEASES  SELLER,  ITS
          OFFICERS,  DIRECTORS,  SHAREHOLDERS,  EMPLOYEES,  REPRESENTATIVES  AND

          WHEN SUCH  CONDITION IS CAUSED BY EVENTS OR  OPERATIONS  OR ACTIVITIES
          OCCURRING  AFTER  THE  EFFECTIVE  DATE  AND,  FURTHER,  FOLLOWING  THE
          EXPIRATION  OF A PERIOD OF TWO (2) YEARS  AFTER  THE  EFFECTIVE  DATE,

                                  ARTICLE VII.
                              ADDITIONAL AGREEMENTS

     7.01 Seller's Disclaimer.  Except as otherwise set forth in this Agreement,
          Seller  disclaims all liability or  responsibility  for any statement,
          information  or data made or  communicated  (orally or in  writing) to
          Buyer,  its  affiliates,  or  any  stockholder,   officer,   director,


                                      E-27

<PAGE>



          employee,  agent, advisor or representative of either (including,  but
          not limited to, any opinion, information or advice which may have been
          provided  to any such  party by any  representative  of  Seller or any
          other party), wherever or however made. Seller makes no representation
          or warranty as to (i) the amounts,  value,  quality, or deliverability
          of hydrocarbons from the Assets,  (ii) any geological,  geophysical or
          other  interpretations  with  respect  to the  Assets  and  (iii)  any
          economic  forecasts,  in each case  whether  contained in any material
          furnished  to Buyer by Seller,  its  officers,  directors,  employees,
          agents,  advisors,   representatives  or  otherwise.  Buyer  expressly
          acknowledges and accepts Seller's disclaimer.

     7.02 Operations  Prior to  Closing.  After the date of this  Agreement  and
          prior to Closing,  Seller shall use and maintain the Assets (including
          the  continuance  of  insurance  coverage) in  substantially  the same
          manner  in which  they have  been  used and  maintained  prior to this
          Agreement.  Unless Seller and Buyer otherwise agree,  Seller shall not
          enter into any  agreement  or  transaction  in relation to the Assets,
          excepting those with unaffiliated third parties which (i) individually
          involve a fair market  value of less than Fifteen  Thousand  ($15,000)
          Dollars and (ii) are entered into in the  ordinary  course of business
          in a manner  consistent  with  prudent  oil field  practices  and JOA;
          provided,  however,  if in  the  sole  judgment  of  the  Seller  such
          conditions  occur with respect to the Assets which would constitute an
          imminent  hazard to property or person or  jeopardize  the  productive
          status of the Assets,  Seller shall act as a  reasonable  operator and
          take such action as is reasonably necessary and make such expenditures
          as are  required  without  the  necessity  of securing  Buyer's  prior
          consent. Buyer shall bear the cost of all expenditures permitted under
          the preceding  sentence in connection  with the operation of the field
          between the date of this  Agreement and Closing.  In the event that an
          expenditure for purposes other than that incurred in normal day-to-day
          operations  is  proposed or  contemplated,  Seller  shall  submit such
          proposal to Buyer for written  concurrence,  absent which Seller shall
          not make such expenditures. Buyer will assume the risk of, and release
          Seller  from,  any  consequences  which  arise as a result of  Buyer's
          failure or refusal to approve and pay such  expenditure.  Unless Buyer
          and Seller otherwise agree, Seller shall not sell,  encumber,  dispose
          of or materially  alter the Assets (other than the use of supplies and
          consumables) or remove any  improvements,  equipment or property which
          comprise the Assets (other than the use of supplies and  consumables),
          with the  exception of  individual  assets (i) involving a fair market
          value of less than Two Thousand  ($2,000.00)  Dollars and (ii) sold or
          transferred to unaffiliated  third parties or consumed in the ordinary
          course of business,  except the sale of oil and/or gas  production  in
          the ordinary course of business.

     7.03 Assumption of Liabilities and Indemnification. Buyer expressly assumes
          all costs,  expenses,  obligations and liabilities associated with the
          Assets after the Effective  Date,  including,  but by no means limited
          to, the proper and lawful plug and  abandonment and  reabandonment  of
          all wells and  facilities  on lands  covered  by the  Leases or pooled
          therewith,  closure of all pits, removal of all flowlines,  pipelines,
          shell pads and pilings, whether now or hereafter, located on the lands
          to be transferred  hereunder in accordance with all requirements under
          law,  including,  but not  limited  to,  the  rules,  regulations  and
          requirements  of  any  governmental   authority  having   jurisdiction
          thereof, specifically including the Department of Conservation,  State
          of  Louisiana  and in  accordance  with all  obligations,  express  or
          implied,  in any agreement  (including  the  applicable  leases) which
          Buyer is required to assume  hereunder  or hereby,  whether or not any
          such  obligations  arise prior to or after the Effective  Date.  BUYER
          SHALL   INDEMNIFY  AND  DEFEND   SELLER,   ITS  OFFICERS,   DIRECTORS,
          SHAREHOLDERS,  AGENTS,  REPRESENTATIVES  AND EMPLOYEES AGAINST ANY AND
          ALL  SUCH  LOSSES,  CLAIMS,  SUITS,  CONTROVERSIES,   LIABILITIES  AND
          EXPENSES,  ARISING OUT OF, OR IN CONNECTION WITH,  OBLIGATIONS ASSUMED
          UNDER THIS PARAGRAPH,  INCLUDING, WITHOUT LIMITATION, THE PLUGGING AND
          ABANDONING AND  REABANDONING OF ANY WELLS,  REMOVAL OR MODIFICATION OF
          FACILITIES, INCLUDING, BUT NOT LIMITED TO, FLOWLINES AND PIPELINES,


                                      E-28

<PAGE>



          CLOSURE OF PITS AND RESTORATION OF SURFACE,  REGARDLESS OF WHETHER THE
          OBLIGATION TO PLUG AND ABANDON AND REABANDON, REMOVE, MODIFY, CLOSE OR
          RESTORE AROSE PRIOR TO, OR SUBSEQUENT TO, THE EFFECTIVE DATE, AND SUCH
          INDEMNIFICATION SHALL EXTEND TO AND INCLUDE CLAIMS OR CAUSES OF ACTION
          BASED  UPON  THE  NEGLIGENCE  OR  STRICT  LIABILITY  OF  SELLER,   ITS
          DIRECTORS,  SHAREHOLDERS,  EMPLOYEES,  REPRESENTATIVES  OR AGENTS. THE
          SALE  WILL BE MADE  EXPRESSLY  SUBJECT  TO THE  TERMS OF ALL  EXISTING
          OPERATING  AGREEMENTS,  UNIT AGREEMENTS,  FARMOUT AGREEMENTS,  LEASES,
          SUBLEASES  AND  ASSIGNMENTS  AS WELL AS ANY AND ALL OTHER  AGREEMENTS,
          WHETHER RECORDED OR UNRECORDED, AFFECTING THE ASSETS.

               Buyer  further  agrees to release and to defend and hold  Seller,
               its officers, directors, shareholders, representatives, employees
               and agents harmless from and against any and all damages, losses,
               expenses (including,  but not limited to, court costs, attorneys'
               fees,  consultant  fees and  investigative  costs and fees),  and
               other  costs  and  liabilities  arising  as a result  of  claims,
               demands and all other  causes of action  (excluding  such claims,
               demands or causes of action made by Seller's  employees,  agents,
               contractors or  representatives)  whether arising out of an event
               or  omission  occurring  subsequent  to the  Effective  Date  and
               without  regard  as to  whether  such  claims  arise  out  of the
               operation  of the Assets by Seller or a third  party and  without
               regard as to whether  such  claims are  asserted by a third party
               (including a governmental  agency) for death,  injury,  damage to
               property or, further,  without regard as to whether such claim is
               based upon the negligence or the strict liability of Seller,  its
               officers, directors, representatives, employees or agents.

     7.04 Use of and Access to Certain Facilities. Certain production, gathering
          and storage facilities  presently existing which serve that portion of
          the Assets described as Righthand Creek Field in Exhibit "B," attached
          hereto,  may be necessary or useful in performing similar services for
          production  derived from East  Righthand  Creek  Prospect.  Therefore,
          Seller shall reserve the right to use such  facilities as capacity may
          permit  and/or erect new  facilities  and/or  construct an  additional
          pipeline  traversing  the Leases to the extent  Seller shall have,  or
          shall obtain,  the third party easements,  surface leases or rights of
          way  entitling  Seller  to use the  surface  of such  lands  for these
          purposes.  The Seller shall expressly  reserve the right of access and
          use of that  certain  gas  pipeline  situated  in  Sections 30 and 31,
          T5S,R7W and in Sections 6 and 7, T6S,R7W,  Allen Parish,  Louisiana to
          the extent  necessary  and to the extent  capacity  is  available,  to
          service  production  derived from East Righthand Creek  Prospect.  The
          location of said gas  pipeline  is  depicted  on Exhibit "H"  attached
          hereto.  In connection  with Seller's use of the  facilities as herein
          provided,  Buyer and Seller  agree to enter into a mutually  agreeable
          facilities use agreement  containing,  among other customary terms and
          conditions, provisions which call for Seller to bear its proportionate
          share  of the  actual  costs  of  operation  and the  actual  costs of
          adapting the facilities for Seller's usage, if necessary.

     7.05 Requested  Data.  Seller  hereby  agrees to provide  true and accurate
          copies of any data or  information  in  Seller's  possession  which is

          a result of automatic  termination or any party hereto  exercising its
          rights to terminate  pursuant to Article  10.01,  then this  Agreement
          shall be null and void and, except as expressly  provided  herein,  no

               the arbitrator(s) within 120 days of the request for arbitration,
               the arbitrator  shall be selected in accordance  with  reasonable
               rules  established by the arbitrators.  The arbitration  shall be
               conducted in accordance with reasonable rules  established by the
               arbitrators. Any award by the arbitrators shall be final, binding
               and  non-appealable,  and judgment may be entered  thereon in any
               court of competent jurisdiction.

     11.16NORM.  It is  expressly  recognized  that the water  bottoms  and land
          masses  comprising  the  Assets,  along with  surface  facilities  and
          production  equipment located thereon,  having been used in connection
          with  oil  and  gas  production  activities,   may  contain  naturally
          occurring   radioactive   materials   (NORM)  as  a  result  of  these
          operations.  Accordingly, lands, water bottoms, surface facilities and
          production  equipment  transferred  herein  are  transferred  with the
          restriction that they will be used only in connection with oil and gas
          producing  activities  associated  with  these  leases and will not be
          subsequently    transferred   for   unrestricted   use,   unless   the
          concentrations  of NORM  associated  therewith  are below  the  levels
          specified as allowable  for  unrestricted  transfer by the  applicable
          regulations  or laws  of the  state  and/or  federal  agencies  having
          regulatory  jurisdiction  there over.  Buyer further agrees to include
          the provisions of this clause in any subsequent  sale or assignment of
          any interest in the Assets herein transferred.

     11.17Seller's  Option to Make  "Like-Kind"  Exchange.  At any time prior to
          Closing,  Seller,  or any one or more of them,  may  elect by  written
          notice to Buyer to  receive  all or a portion  of the  Purchase  Price
          through an escrow  agent  designated  by Seller  pursuant to an escrow
          agreement  to be  established  for  purposes of  effecting a tax free,
          like-kind  exchange under Section 1031 of the Internal Revenue Code of
          1986,  as  amended.  Buyer  agrees to  cooperate  with all  reasonable
          requests of Seller in order to establish and create

                                      E-36

<PAGE>



          sufficient  documentation  to support  such  federal tax  treatment by
          Seller,  provided  that Buyer shall have no obligation to incur or pay
          any cost or expense in such connection,  and provided,  further,  that
          Buyer shall have no obligation to acquire any  properties  (other than
          the  Assets) in  connection,  with such  exchange  or to  execute  any
          agreements or other documents or to undertake any other action whereby
          Buyer might incur or assume any  indebtedness  or other  liability  in
          connection with such exchange.

          If Seller appoints an Intermediary pursuant to this paragraph,  it may
          transfer  the  Assets  to  the  Intermediary,   and  at  Closing,  the
          Intermediary  shall  transfer  the  Assets to the  Buyer  and  receive
          consideration  payable at Closing  from  Buyer,  all  pursuant to this
          Agreement.   The  payment  by  Buyer  of  such  consideration  to  the
          Intermediary  shall be treated as satisfaction of Buyer's  obligations
          under the  Agreement  to the same  extent as if such  payment had been
          made directly to Seller. Seller agrees that the transfer of the Assets
          to the  Intermediary  shall expressly be subject to this Agreement and
          that Seller shall remain liable for  performance  under this Agreement
          and all  documents to be delivered at Closing to the same extent as if
          it  had  not  appointed  an   Intermediary.   If  Seller  appoints  an
          Intermediary,  Buyer  shall  not be  obligated  to pay any  additional
          costs, or incur any additional obligations,  in the acquisition of the
          Assets,  and Seller shall  indemnify and hold Buyer and its affiliates
          harmless from and against all claims, expenses, losses and liabilities
          resulting from the Intermediary's participating in the purchase.

     11.18Broker's  Commission.  Buyer  shall pay in full by wire  transfer,  in
          immediately  available  funds, all commissions due at Closing to Burks
          Oil and Gas Properties,  Inc. or to its designees,  such payment to be
          made  in the  same  manner  as,  and  concurrently  with,  any and all
          payments made to Seller.

     11.19Further Assurances.  After Closing,  each party hereto, at the request
          of the other, shall from time to time without additional consideration
          execute  and  deliver  such  further  agreements  and  instruments  of
          conveyance  and take such other  action as the other party  hereto may
          reasonably  request in order to convey and deliver the Assets to Buyer
          and to  otherwise  accomplish  the  transactions  contemplated  by the
          Agreement.

     11.20No Punitive  Damages.  Under no  circumstances  shall  either Party be
          liable  to the  other  for  any  indirect,  consequential,  unforseen,
          exemplary or punitive damages of any nature.

     7.   ESCROW AGENT. Escrow Agent acts hereunder solely as a depository,  and
          the  responsibility  of the Escrow  Agent  extends  only to the duties
          affirmatively stated in this Agreement and to the exercise of ordinary
          diligence.  No implied  duties or obligations of Escrow Agent shall be
          read into this  Escrow  Agreement,  and Escrow  Agent shall not in any
          event be required to  construe  or  determine  the rights of any party
          under this Agreement.

          Escrow Agent shall in no way be responsible for, nor shall it have any
          duty to notify, any party hereto or any other party interested in this
          Escrow Agreement of any payment  required or maturity  occurring under
          this Escrow  Agreement or under the terms of any instrument  deposited
          hereunder.

          Escrow  Agent  may  consult  with  its  attorneys  as to  any  matters
          incidental to duties  hereunder and shall be fully protected and incur
          no liability when acting thereon in accordance  with the advice of its
          attorneys.  Escrow  Agent  shall  not be  responsible  for  any act or
          omission,  except for actual fraud,  dishonesty  or bad faith.  Escrow
          Agent may rely upon any such  instructions and deliver the Escrow Fund
          as  directed  without  further  investigation.  Escrow  Agent shall be
          protected in acting upon any written notice, request, waiver, consent,
          certificate, receipt, authorization,  power of attorney or other paper
          or document that Escrow Agent,  in good faith,  believes to be genuine
          and what it purports  to be,  including,  but not  limited  to,  items
          directing  investment or non-investment of funds,  items requesting or
          authorizing  release,  disbursement or retainage of the subject matter
          of Escrow  Agreement  and  items  amending  the  terms of this  Escrow
          Agreement.

          In the event of dispute  arising  between and/or among any two or more
          of the parties  hereto,  or if a claim is asserted with respect to the
          Escrow Fund, the Escrow Agent may withhold any requested  action until
          the dispute is amicably resolved.  In any event, Escrow Agent reserves
          the right to deposit all property in its possession in connection with
          this Agreement into the registry of a court of competent  jurisdiction
          in a  concursus  or other  proceeding,  upon  directing  Notice to the
          parties as provided hereinabove,  and thereby shall be relieved of any
          further responsibility under this Agreement. The Escrow Agent shall be
          entitled to reimbursement  for all legal fees and costs incurred by it
          in connection  with any concursus,  interpleader or other action filed
          by Escrow Agent  hereunder and in connection with any dispute or claim
          involving the distribution of the Escrow Fund.

          Each  person  comprising  Principal  hereby  jointly,   severally  and
          solidarily agrees to indemnify and hold harmless the Escrow Agent from
          and against all losses, costs, claims,  demands,  expenses and damages
          and attorneys fees suffered or incurred by Escrow Agent as a result of
          any  litigation or cause of action  arising  from,  or in  conjunction
          with, this Agreement or involving the subject matter hereof.

          If any party to this  Agreement is a legal entity other than a natural
          person, the Escrow Agent may conclusively presume that the undersigned
          representative  of such party has full power and authority to instruct
          Escrow  Agent on behalf of such party,  unless  written  notice to the
          contrary is delivered to Escrow Agent.

     8.   *COMPENSATION, FEES, ETC. Escrow Agent shall be entitled to reasonable
          compensation for its services  hereunder and to reimbursement  for its
          costs and  expenses in  connection  with its  performance  of services
          under this Agreement (including amounts  representing  reasonable fees

                                       E-4

<PAGE>



          and  expenses  of  Escrow  Agent's  counsel  and  accountants).   Such
          compensation,  fees,  costs and expenses shall be paid from the income
          earned on the Escrow Fund, but if such amounts are unpaid, in whole or
          in part,  the Escrow  Agent shall be  entitled to deduct such  amounts
          from the Escrow Fund.

     9.   ASSIGNMENT. No assignment of the rights of any party to this Agreement
          shall be valid and  enforceable  without the prior written  consent of
          all of the parties hereto.

     10.  SUCCESSOR ESCROW AGENT.  Escrow Agent may resign at any time by giving
          written  notice to the other parties  hereto,  whereupon  such parties
          agree  to  immediately  appoint  a  successor  escrow  agent.  Until a
          successor  escrow agent has been named and accepts its  appointment or
          until another  disposition  of the Escrow Fund has been agreed upon by
          all parties  hereto,  Escrow Agent shall be  discharged  of all of its
          duties hereunder save to keep the Escrow Fund whole.

*      Such compensation not to exceed the sum of $1,000.00.
*      Such fees not to exceed the sum of $500.00.

     12.  CONTROLLING  LAW. The validity of this Agreement,  the construction of
          its  terms  and the  determination  of the  rights  and  duties of the
          parties hereto shall be governed by, and construed in accordance with,
          the laws of the State of Louisiana.
