(a)      On  November  16,  1998,  Abraxas  Petroleum   Corporation,   a  Nevada
         corporation (the "Company"),  sold its natural gas producing properties
         in the Wamsutter area of  southwestern  Wyoming's  Green River Basin to
         Abraxas Wamsutter L.P., a Texas limited partnership (the "Partnership")
         for  consideration  of $58.6 million and a minority  equity interest in
         the Partnership. A subsidiary of the Company, Wamsutter Holdings, Inc.,
         a Wyoming  corporation,  (the "General Partner"),  will initially own a
         one percent interest and act as the general partner of the Partnership.

         subsidiary of GE Capital  Structure  Finance Group, will be the limited
         partner and initially own ninety-nine percent of the Partnership. After
         certain payback requirements are satisfied, the Company's interest will
         increase to 35%  initially  and could  increase to as high as 65%.  The
         Company  will also receive a 1%  management  fee and  reimbursement  of

         Section  4.7.  Basic  Documents.  The oil, gas and/or  mineral  leases,
Seller's  interests in which comprise parts of the Oil and Gas  Properties,  and
all other material  contracts and agreements,  licenses,  permits and easements,
rights-of-way  and  other  rights-of-surface  use  comprising  any  part  of  or
otherwise  relating to the Properties  including,  but not by way of limitation,
the TGas  Contracts  (such  leases  and  such  material  contracts,  agreements,
licenses,  permits,  easements,  rights-of-way and other  rights-of-surface  use
being herein called the "Basic Documents"), are in all material respects in full
force and effect and  constitute  valid and binding  obligations  of the parties
thereto.  All material  contracts and agreements  which are Basic  Documents are
disclosed on Exhibit II in connection  with the  descriptions of the Oil and Gas
Properties  to which they  relate.  Seller is not in breach or  default  (and no
situation exists which with the passing of time or giving of notice would create
a breach or default) of its obligations  under the Basic Documents,  and (to the
best of  Seller's  knowledge)  no  breach  or  default  by any  third  party (or
situation  which  with the  passage of time or giving of notice  would  create a
breach or default)  exists,  to the extent  such  breach or default  (whether by
Seller  or such a third  party)  could  reasonably  be  expected  to  materially
adversely  affect  the  ownership,  operation,  value  or use of any Oil and Gas
Property after the Effective Date. All payments (including,  without limitation,
all delay rentals,  royalties,  shut-in royalties and valid calls for payment or
prepayment under operating agreements) owing under Basic Documents have been and
are being made (timely,  and before the same became delinquent) by Seller in all
material  respects  (and,  where the  non-payment of same by a third party could
materially adversely affect the ownership, operation, value or use of an Oil and
Gas Property after the Effective Date, have been and are being made, to Seller's
knowledge,  by such third  parties).  For the  purposes  of the  representations
contained in this Section (and without limitation of such representations),  the
non-payment  of an  amount,  or  non-performance  of an  obligation,  where such
non-payment,  or non-performance,  could result in the forfeiture or termination
of rights of Seller under a Basic Document, shall be considered material.

         Section 4.8.  Commitments,  Abandonments  or  Proposals.  Except as set
forth in Section 4.8 of the Seller Disclosure Schedule:  (a) Seller has incurred
no  expenses,  and has  made no  commitments  to make  expenditures  (including,
without  limitation,  Seller  has not  entered  into any  agreements  that would
obligate  Buyer  to  make  expenditures),  in  connection  with  (and  no  other
obligations or liabilities have been incurred which would adversely  affect) the
ownership or operation of the Properties  after the Effective  Date,  other than
routine  expenses  incurred in the normal operation of existing wells on the Oil
and Gas  Properties;  (b) Seller has not  abandoned  any wells (or  removed  any
material items of equipment,  except those replaced by items of materially equal
suitability) on the Oil and Gas Properties  since the Effective Date; and (c) no
proposals  are  currently  outstanding  (whether  made by Seller or by any other
party) to drill  additional  wells, or to deepen,  plug back, or rework existing
wells,  or to conduct other  operations  for which consent is required under the
applicable  operating  agreement,  or to conduct any other operations other than
normal operation of existing wells on the Oil and Gas Properties,  or to abandon
any wells, on the Oil and Gas Properties.

         Section 4.9.  Production Sales Contracts.  There exist no agreements or
arrangements  for  the  sale of  production  from  the  Oil  and Gas  Properties
(including  without   limitation,   calls  on,  or  other  rights  to  purchase,
production,  whether or not the same are currently being  exercised)  other than
(a) production sales contracts (in this Section, the "Scheduled Production Sales
Contracts")  disclosed in Section 4.9 of the Seller  Disclosure  Schedule or (b)
agreements  or  arrangements  which  are  cancelable  on 90 days  notice or less
without  penalty or  detriment.  Seller is  presently  receiving a price for all
production  from (or  attributable  to) each Oil and Gas  Property  covered by a
Scheduled  Production Sales Contract as computed in accordance with the terms of
such contract, and is not having deliveries of gas from any Oil and Gas Property
subject to a Scheduled  Production Sale Contract curtailed  substantially  below
such property's delivery capacity.

         Section  4.10.  Plugging  and  Abandonment.  Except for wells listed in
Section 4.10 of the Seller Disclosure Schedule,  there are no dry holes, or shut
in or otherwise  inactive  wells,  located on the Oil and Gas  Properties  or on
lands pooled or unitized therewith,  except for wells that have been plugged and
abandoned,  and except for wells  drilled to depths not included  within the Oil
and Gas  Properties  or  within  units  in  which  the  Oil  and Gas  Properties
participate which have never been completed in such depths.

         Section  4.11.  Licenses  and  Permits.  Seller  has  all  governmental
licenses and permits  necessary or appropriate to own and operate the Properties
as presently  being owned and  operated,  if the failure to have such license or
permit would have a material adverse affect with respect to the Properties,  and
such  licenses,  permits  and  filings  are in full  force and  effect  (and are
transferrable  to Buyer or are subject to being routinely  replaced by a license
or permit issued to Buyer as a successor  owner of the  Properties),  and Seller
has not  received  written  notice  of any  violations  in  respect  of any such
licenses or permits.

         Section  4.12.  Area of  Mutual  Interest  and  Other  Agreements;  Tax
Partnerships.  No Oil and Gas  Property is subject to (or has related to it) any
area of mutual  interest  agreements.  No Oil and Gas Property is subject to (or
has  related to it) any  farm-out  or farm-in  agreement  under  which any party
thereto  is  entitled  to  receive  assignments  not yet  made,  or  could  earn
additional  assignments  after the  Effective  Date.  No Oil and Gas Property is
subject to (or has related to it) any tax partnership.

         Section 4.13.  Payment of Expenses.  All expenses  (including,  without
limitation,  all bills for labor,  materials  and supplies used or furnished for
use in  connection  with  the  Properties,  and all  severance,  production,  ad
valorem,  windfall  profit and other similar taxes) relating to the ownership or
operation of the Properties,  have been, and are being, paid (timely, and before
the same become  delinquent)  by Seller,  except such  expenses and taxes as are
disputed  in good faith by Seller and for which an adequate  accounting  reserve
has been established by Seller.

         Section 4.14. Compliance with Laws. As to Properties operated by Seller
and, to Seller's knowledge with respect to Properties operated by third parties,
the   ownership   and   operation  of  the   Properties,   to  the  extent  that
non-conformance  could adversely affect the ownership,  operation,  value or use
thereof  after the  Effective  Date (or  otherwise  affect  Buyer),  has been in
conformity,  in all  material  respects,  with  all  applicable  laws,  and  all
applicable  rules,  regulations and orders of all  governmental  agencies having
jurisdiction,  relating  to the  Properties.  Without  in any way  limiting  the
foregoing representations, the Properties are not in violation of (or subject to
any  existing,   pending  or,   threatened   investigation  or  inquiry  by  any
governmental  authority,  or to any remedial  obligations  under) any applicable
laws,  rules,  regulations  or orders  pertaining to health or the  environment,
including those relating to waste materials or hazardous substances (hereinafter
sometimes   collectively  called  "applicable   environmental   laws").   Seller
undertook,  at the  times  of its  respective  acquisitions  of the  Properties,
appropriate  inquiry  into the  previous  ownership  and uses of the  Properties
consistent  with good  commercial  or customary  practice,  and Seller has taken
reasonable  steps  necessary to determine and has  determined  that no hazardous
substances  or solid wastes (as defined in the  applicable  environmental  laws)
have been  disposed  of or  otherwise  released  on or to the  Properties.  Also
without limitation of the foregoing,  all oil and gas wells comprising a part of
the  Properties  have been drilled and  completed  within the  boundaries of the
applicable  leases  or  within  limits  otherwise   permitted  by  a  valid  and
enforceable pooling,  unit, or other agreement or contract or by applicable law,
and no well comprising a part of the Properties is or was subject to any penalty
on allowables  after the Effective Date because of any  over-production  (or any
other  judgments,  orders or decrees of any court or  governmental  authority or
agency)  which would (or did) prevent such well from being  entitled to its full
legal and regular  allowable (as prescribed by any court or governmental body or
agency) from and after the Effective Date.

         Section 4.15. Information furnished to Cawley,  Gillespie & Associates.
All information furnished by Seller or its representatives to Cawley,  Gillespie
& Associates,  Inc. in connection  with the  preparation of the initial  reserve
report was true and correct in all material respects.

         Section 4.16. Disclaimer of Warranties.  Other than those expressly set
out in this Article IV or in Exhibit 9.2(a),  Seller hereby expressly  disclaims
any and all  representations or warranties with respect to the Properties or the
transaction  contemplated hereby, and Buyer agrees that the Properties are being
sold by Seller "where is" and "as is", with all faults.  Specifically  as a part
of (but not in limitation of) the foregoing,  Buyer acknowledges that Seller has
not made, and Seller hereby expressly disclaims,  any representation or warranty
(express,  implied,  under  common  law,  by  statute  or  otherwise)  as to the
condition of the Properties (INCLUDING WITHOUT LIMITATION,  SELLER DISCLAIMS ANY
IMPLIED  OR  EXPRESS  WARRANTY  OF  MERCHANTABILITY,  FITNESS  FOR A  PARTICULAR
PURPOSE, OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS).

         Buyer  acknowledges  that it has made its own independent  examination,
investigation,  analysis and evaluation of the Properties, including Buyer's own
estimate  of the  value  of  the  Properties.  Buyer  acknowledges  that  it has
undertaken such due diligence as Buyer deems adequate,  including that described
above.  Buyer  acknowledges  and  agrees  that  neither  Seller  nor  any of its
shareholders,   officers,   directors,   employees   or  other   representatives
(collectively,   the  "Seller  Parties")  shall  be  deemed  to  have  made  any
representation  or warranty  other than as expressly set forth  herein.  Without
limiting the  generality  of the  foregoing  and  notwithstanding  any otherwise
express representations and warranties made by any of the Seller Parties herein,
the Seller Parties make no representation or warranty with respect to:

                  (a) any projections, estimates or budgets heretofore delivered
                  to or made available to Buyer of future revenues,  expenses or
                  expenditures or future results of operations; or

                  (b)  except  as  expressly  covered  by a  representation  and
                  warranty  contained herein, any other information or documents
                  (financial  or  otherwise)  made  available  to  Buyer  or its
                  counsel, accountants, advisers or representatives.

                                   ARTICLE VI

                   Certain Covenants of Seller Pending Closing

         Section  6.1.  Access to Files.  From the date  hereof  until  Closing,
Seller will give Buyer, and its attorneys and other  representatives,  access at
all reasonable times to the Properties and to any contract files, lease or other
title files,  production  files, well files and other files of Seller pertaining
to the ownership  and/or  operation of the  Properties,  and Seller will use its
reasonable  best  efforts to  arrange  for Buyer,  and its  attorneys  and other
representatives,  to have  access to any such  files in the  office  of  Seller.
Seller  shall not be  obligated  to provide  Buyer with access to any records or
data which Seller cannot  provide to Buyer  without,  in its opinion,  breaching
confidentiality agreements with other parties.

         All  access  to the  Properties  shall  be at the sole  cost,  risk and
expense of Buyer,  and Buyer agrees to indemnify  Seller from any and all losses
which may  result,  directly  or  indirectly,  from  Buyer's  inspection  of the
Properties.  All  information  obtained by Buyer shall be  maintained  in strict
confidence,  for use solely in connection with its evaluation of the Properties,
and shall not be disclosed to any other party  without  Seller's  prior  written
consent.

<PAGE>
         Section  6.2.  Conduct of  Operations.  Seller  will (a)  continue  the
routine  operation of the  Properties in the ordinary  course of business and as
would a prudent  operator,  (b) operate the  Properties  in  conformity  (in all
material   respects)  with  all  applicable  laws,  and  all  applicable  rules,
regulations and orders of all governmental agencies having jurisdiction,  and in
conformity  with all oil, gas and/or mineral  leases,  and in conformity (in all
material  respects)  with all Basic  Documents  other than such leases,  and (c)
fulfill all obligations  (including  without  limitation all obligations to make
payments under leases or other Basic Documents)  under such leases,  and (in all
material  respects)  under  such  other  Basic  Documents  and (in all  material
respects) under such laws, rules,  regulations and orders (without limitation of
the  foregoing,  the failure to perform an  obligation,  when such failure could
result in forfeiture or termination of rights of Seller under a Basic  Document,
shall be considered material).

         Section 6.3. Restrictions on Certain Actions.  Seller will not, without
Buyer's prior consent:

         (a)  expend  any  funds,  or  make  any  commitments  to  expend  funds
(including,  without  limitation,  entering  into  new  agreements  which  would
obligate Seller to expend funds),  or otherwise  incur any other  obligations or
liabilities,  in connection  with the  ownership or operation of the  Properties
after the Effective  Date,  other than routine  expenses  incurred in the normal
operation of the  existing  wells on the Oil and Gas  Properties,  except in the
event of an emergency requiring immediate action to protect life or preserve the
Properties;

         (b) except where necessary to prevent the termination of an oil and gas
lease or other material agreement governing Seller's interest in the Properties,
propose the drilling of any additional wells, or propose the deepening, plugging
back or reworking of any existing  wells, or propose the conducting of any other
operations which require consent under the applicable  operating  agreement,  or
propose the conducting of any other  operations  other than the normal operation
of the existing wells on the Oil and Gas Properties,  or propose the abandonment
of any  wells on the Oil and Gas  Properties  (and  Seller  agrees  that it will
advise  Buyer of any such  proposals  made by third  parties and will respond to
each such proposal made by a third party in the manner requested by Buyer),;

         (c) sell,  transfer or abandon any portion of the Properties other than
items  of  materials,  supplies,  machinery,  equipment,  improvements  or other
personal property or fixtures forming a part of the Properties (and then only if
the same is replaced with an item of substantially  equal  suitability,  free of
liens and security interests, which replacement item will then, for the purposes
of this Agreement, become part of the Properties) ; or

         (d)  release (or permit to  terminate),  or modify or reduce its rights
under,  any oil,  gas  and/or  mineral  lease  forming a part of the Oil and Gas
Properties,  or any other Basic Document, or enter into any new agreements which
would be Basic Documents,  or modify any existing  production sales contracts or
enter into any new production  sales contracts,  except contracts  terminable by
Seller with notice of sixty (60) days or less.

production,  windfall  profit and similar  taxes)  relating to the  ownership or
operation of the Properties prior to the date of Closing to be promptly paid and
discharged, except for expenses disputed in good faith.

<PAGE>
         Section 6.5. Preferential Rights and Third Party Consents.  Seller will
request,  from the  appropriate  parties (and in  accordance  with the documents
creating such rights and/or requirements), waivers of the preferential rights to
purchase,  or  requirements  that consent to assignment  be obtained,  which are
identified on Exhibit 6.5. Seller shall have no obligation  hereunder other than
to so request such waivers (i.e., Seller shall have no obligation to assure that
such waivers are  obtained),  and if all such  waivers (or any other  waivers of
preferential  rights to purchase  or  requirements  that  consent be obtained to
assignment,  even if the  same  are not  listed  on such  Exhibit  6.5)  are not
obtained,  Buyer may treat any waiver  which is not  obtained as a matter  which
causes  Seller's  title to not be  sufficient to meet the standards set forth in
Article VII; provided,  however,  that if the unobtained waiver is a waiver of a
preferential  right to  purchase,  and if both  Buyer and  Seller  agree to this
treatment  of such  matter  (and agree  upon an  appropriate  allocation  of the
Purchase  Price),  Seller  will tender (at the agreed  allocated  portion of the
Purchase Price) the required  interest in the Property affected by such unwaived
preferential right to purchase to the holder, or holders, of such right who have
elected not to waive such  preferential  right to  purchase,  and if, and to the
extent that, such  preferential  right to purchase is exercised by such party or
parties,  such interest in such  Property will be excluded from the  transaction
contemplated  hereby and the Purchase  Price will be reduced by the amount paid,
or to be paid, by the party exercising such preferential  right to purchase (and
Seller shall collect such amount from such purchaser).


                                   ARTICLE VII

                            Due Diligence Examination

         Section 7.1.  Inspection and Assertion of Defects.

         (a) Buyer may, to the extent it deems appropriate, conduct, at its sole
cost, such title  examination or  investigation as it may choose to conduct with
respect  to  the  Properties.  Should,  as a  result  of  such  examination  and
investigation,  or  otherwise,  matters  come to Buyer's  attention  which would
constitute "Defects" (as below defined), and should there be one or more of such
Defects  which  Buyer  determines  it  is  unwilling  to  waive  and  close  the
transaction  contemplated  hereby  notwithstanding  the fact that  such  Defects
exist,  Buyer  shall  notify  Seller in writing  of such  Defects at or prior to
Closing.  Such  Defects of which  Buyer so  provides  notice  are herein  called
"Asserted  Defects."  All Defects  with  respect to which Buyer fails to so give
Seller notice will be deemed  waived for all  purposes.  In the event that Buyer
notifies  Seller of Asserted  Defects,  Seller shall have the right (but not the
obligation)  to  attempt  to  cure,  such  Asserted  Defects  to the  reasonable
satisfaction  of Buyer,  and for the  purpose of curing such  Asserted  Defects,
Seller may on written notice to Buyer elect to delay Closing for a period not to
exceed 14 days.

         (b) The term "Defect" as used in this Section shall mean the following:

                  (i) Seller's  ownership of the  Properties is such that,  with
         respect to a well listed on Exhibit  7.1(b)(i)  hereto, it (A) entitles
         Seller  to  receive  a  percentage  share  of the  oil,  gas and  other
         hydrocarbons  produced  from,  or allocated to, such well which is less
         than the percentage share set forth on Exhibit  7.1(b)(i) in connection
         with such well in the column  headed  "NRI" or (B) causes  Seller to be
         obligated to bear a  percentage  share of the cost of operation of such
         well greater than the percentage  share set forth on Exhibit  7.1(b)(i)
         in  connection  with such well in the column  headed  "WI"  (unless the
         share of  production  from such well to which  Seller  is  entitled  is
         proportionately  larger  than the "NRI"  shown for such well on Exhibit
         7.1(b)(i)); or

                  (ii) Seller's  ownership of an Oil and Gas Property is subject
         to a lien other than (A) a lien for taxes not yet delinquent,  or (B) a
         mechanic's or  materialmen's  lien (or other similar  lien),  or a lien
         under an operating  agreement or similar  agreement,  to the extent the
         same relates to expenses incurred which are not yet due; or

                  (iii) Seller's ownership of an Oil and Gas Property is subject
         to a preferential right to purchase such property or a requirement that
         consent to assignment of such property be obtained,  unless a waiver of
         such  right  has  been  obtained   with  respect  to  the   transaction
         contemplated  hereby  or,  in  the  case  of a  preferential  right  to
         purchase,  an appropriate  tender of the  applicable  interest has been
         made to the party  holding  such right and the period of time  required
         for such party to exercise  such right has expired  without  such party
         exercising such right; or

                  (iv) Seller's  ownership of an Oil and Gas Property is subject
         to an imperfection  in title which, if asserted,  would cause a Defect,
         as  defined in clause (i) above,  to exist,  and such  imperfection  in
         title is not such as would normally be waived by persons engaged in the
         oil and gas business who are purchasing producing properties; or

                  (v) An Oil and Gas Property is subject to a makeup  obligation
         to satisfy  take-or-pay  payments or other  prepayments  for production
         previously received by Seller; or

                  (vi) Seller is in an overproduced  position with respect to an
         Oil and Gas Property  (e.g.,  Seller and/or its  predecessors  in title
         have taken more gas than their  ownership  in such Oil and Gas Property
         would entitle them to take), and such overproduced  position is greater
         than that shown on Exhibit 7.1(b)(vi).

                  Buyer  acknowledges  that the wells indicated with an asterisk
         (*) on Exhibit 7.1(b)(i) are subject to that certain  Assignment of Oil
         and Gas Leases with  Reservation of Production  Payment dated effective
         as of  August  1,  1995,  from  Dalen  Resources  Oil & Gas Co. to TGas
         Investments  LLC,  and  Buyer  agrees  that such  Assignment  shall not
         constitute a Defect as provided in Section 7.1(b)(i), provided that the
         Net Profits Account upon which the Production  Payment reserved therein
         is payable  shall be credited  with a percentage  share of the oil, gas
         and other hydrocarbons  produced from, or allocated to, such well which
         is not less than the percentage share set forth on Exhibit 7.1(b)(i) in
         connection  with  such  well in the  column  headed  "NRI" and shall be
         charged with a  percentage  share of the cost of operation of such well
         not greater than the percentage share set forth on Exhibit 7.1(b)(i) in
         connection  with such  well in the  column  headed  "WI",  and  further
         provided  that the option to  purchase  such wells which is included in
         the TGas Contracts,  if exercised,  would entitle Buyer to a percentage
         share  of the  oil,  gas  and  other  hydrocarbons  produced  from,  or
         allocated  to,  such  well  which is not less than the NRI set forth on
         Exhibit  7.1(b)(i) and would obligate Buyer to bear a percentage  share
         of the cost of operation of such well not greater than the WI set forth
         on Exhibit 7.1(b)(i) in connection with such wells.

         Section 7.2.  Certain Price Adjustments.

         (a) In the event that, as a part of the due diligence  review  provided
for in Section 7.1 above, Asserted Defects are presented to Seller and Seller is
unable (or unwilling) to cure such Asserted Defects prior to Closing,  or in the
event that  Buyer has  elected to treat an Oil and Gas  Property  affected  by a
casualty  loss as if it was an Oil  and Gas  Property  affected  by an  Asserted
Defect (as provided in Article XII), then:

                  (i) Buyer and Seller  shall,  with respect to each Oil and Gas
         Property  affected by one or more  Asserted  Defects,  attempt to agree
         upon an  appropriate  adjustment  to the Purchase  Price to account for
         such Asserted Defects; and

                  (ii) with  respect  to each Oil and Gas  Property  as to which
         Buyer and Seller are  unable to agree  upon an  appropriate  adjustment
         with  respect  to all  Asserted  Defects  affecting  such  Oil  and Gas
         Property,  such  Oil  and  Gas  Property  will  be  excluded  from  the
         transaction contemplated hereby, and the Purchase Price will be reduced
         by the amount attributed on Exhibit 7.2 to such Oil and Gas Property.

Notwithstanding  anything herein to the contrary,  Buyer may elect to specify as
an appropriate  adjustment to the Purchase  Price (A) for an Asserted  Defect of
the type which is specified  in Section  7.1(b)(i)  or Section  7.1(b)(iv),  and
which  relates to the NRI specified on Exhibit  7.1(b)(i),  an amount equal to X
multiplied  by Y, where "X" is the amount  specified  on Exhibit 7.2 for the Oil
and  Gas  Property  to  which  such  Defect  relates,   and  where  "Y"  is  the
proportionate  reduction  in such NRI  (e.g.,  the  amount by which the share of
production  to which Seller is actually  entitled is less than the NRI specified
for  such  Oil and Gas  Property  on  Exhibit  7.1(b)(i),  divided  by such  NRI
specified on Exhibit  7.1(b)(i)),  or (B) for a Defect of the type  specified in
Section  7.1(b)(ii),  Section  7.1(b)(v),  or  Section  7.1(b)(vi),  the  amount
required  to  discharge  such  lien,  or the amount  represented  by the loss of
volumes required to discharge such make up obligation or overproduced  position,
which  amounts  shall,  in the  case of a make  up  obligation  or  overproduced
position,  be the discounted  present value of the volumes required to discharge
such  obligation,  determined by using a 10% discount rate and assuming the same
would be  discharged  as  promptly as  possible  (under the terms of  applicable
agreements)  after the Closing Date assuming  production occurs at the same rate
as projected in projections of production furnished by Buyer as (and represented
by Buyer to be) its  projections  used in making its  decision to purchase  (and
valuing  such   production   using  prices  for  production   utilized  in  such
projections).


                                       17
<PAGE>


         (b) Should Seller  determine (or should Buyer, in the course of its due
diligence review  contemplated by Section 7.1,  determine) that the ownership of
the Properties by Seller  entitles  Seller to a share of the  production  from a
well  listed on Exhibit  7.1(b)(i)  greater  than the share  shown for such well
under the column  headed  "NRI" on Exhibit  7.1(b)(i),  or that  Seller is in an
underproduced  position  with respect to an Oil and Gas Property  (e.g.,  Seller
and/or its  predecessors  in title have taken less gas than their  ownership  in
such Oil and Gas Property would entitle them to take),  or is in an overproduced
position  less than that  shown on  Exhibit  7.1(b)(vi),  then  Seller  shall be
entitled to an upward  adjustment to the Base Purchase Price to account for such
fact,  in which case such  adjustment  shall be  handled in a similar  manner as
provided above with respect to adjustments for Asserted  Defects;  provided that
the party making such determination shall notify the other party of the proposed
upward adjustment at or prior to Closing.

         Section 7.3. Waiver.  Without limiting Section 7.1 and  notwithstanding
anything else herein to the contrary, all Defects not raised by Buyer within the
time period  specified in Section 7.1 shall be waived by Buyer for all purposes,
and Buyer shall have no right to seek an adjustment to the Purchase Price,  make
a claim against Seller or seek indemnification from Seller with respect thereto,
and all proposed upward  adjustments not raised by Seller within the time period
specified in Section 7.1 shall be waived by Seller for all purposes,  and Seller
shall have no right to seek an  adjustment to the Purchase  Price,  make a claim
against Buyer or seek indemnification from Buyer with respect thereto.

obligations  hereunder,   this  Agreement  may,  at  the  option  of  Buyer,  be
terminated,  in which case the parties shall have no further  obligations to one
another  hereunder  (other than the  obligations  under  Article XIV and Section

transactions contemplated hereby are financially fair.

         (f) Buyer and Seller shall have entered into a mutually acceptable AAPL
Form 610 (1982) Model Form Contract  Operating  Agreement  designating Seller as
contract  operator  under those Oil and Gas Properties  currently  owned 100% by

to the Partnership Agreement.

         (g) Seller shall have  received the consent of its lenders  pursuant to

1996,  by and  among  Seller,  Bankers  Trust  Company  and ING  (U.S.)  Capital
Corporation, as Co-Agents, and the Banks named therein, as amended.

If any such  condition on the  obligations of Seller under this Agreement is not
met as of the Closing  Date,  or in the event the  Closing  does not occur on or
before the Closing  Date,  and (in either  case)  Seller is not in breach of its
obligations  hereunder  in the  absence  of Buyer  also  being in  breach of its
obligations  hereunder,  this  Agreement  may,  at  the  option  of  Seller,  be
terminated,  in which case the parties shall have no further  obligations to one
another  hereunder  (other than the  obligations  under  Article XIV and Section
15.5, which will survive such termination).

                         Certain Accounting Adjustments.


                                       21
<PAGE>


         Section  10.1.  Adjustments.  Appropriate  adjustments  shall  be  made
between  Buyer  and  Seller  so  that  (a)  all  expenses  (including,   without
limitation,  all  drilling  costs,  all capital  expenditures,  and all overhead
charges under applicable  operating  agreements,  and all other overhead charges
actually  charged by third  parties)  which are incurred in the operation of the
Properties  after the  Effective  Date will be borne by Buyer,  and all proceeds
(net of applicable  production,  severance,  and similar taxes) from the sale of
oil, gas and/or other minerals  produced from the Oil and Gas  Properties  after
the  Effective  Date will be received by Buyer,  and (b) all expenses  which are
incurred in the operation of the  Properties  before the Effective  Date will be
borne by Seller and all proceeds (net of applicable production,  severance,  and
similar  taxes)  from  the  sale of oil,  gas  and/or  other  minerals  produced
therefrom  before the  Effective  Date will be received by Seller.  It is agreed
that,  in making such  adjustments:  (i) oil which was produced from the Oil and
Gas Properties and which was, on the Effective Date,  stored in tanks located on
the Oil and Gas Properties (or located  elsewhere but used to store oil produced
from the Oil and Gas Properties  prior to delivery to oil  purchasers) and above
pipeline  connections shall be deemed to have been produced before the Effective
Date (it is recognized that such tanks were not gauged on the Effective Date for
the purposes of this Agreement and that  determination of the volume of such oil
in  storage  will be  based  on the  best  available  data,  which  may  include
estimates),  and (ii) ad valorem  taxes  assessed with respect to a period which
the Effective  Date splits shall be prorated based on the number of days in such
period which fall on each side of the Effective  Date (with the day on which the
Effective Date falls being counted in the period after the Effective  Date), and
(iii) no consideration  shall be given to the local, state or federal income tax
liabilities of any party.

         Section 10.2.  Closing and Post-Closing Accounting Settlements.

         (a) At or before Closing,  the parties shall determine,  based upon the
best  information  reasonably  available to them, the amount of the  adjustments
provided for in Section 10.1. If the amount of adjustments  so determined  which
would result in a credit to Buyer exceed the amount of adjustments so determined
which would result in a credit to Seller,  Buyer shall receive a credit, for the
amount of such excess, against the Purchase Price to be paid at Closing, and, if
the  converse  is true,  Buyer shall pay to Seller,  at Closing (in  addition to
amounts otherwise then owed), the amount of such excess.

         (b) On or before 90 days after  Closing,  Buyer and Seller shall review
any  additional  information  which  may  then be  available  pertaining  to the
adjustments  provided for in Sections  10.1,  shall  determine if any additional
adjustments  (whether  the same be made to account for  expenses or revenues not
considered in making the adjustments made at Closing,  or to correct errors made
in such adjustments) should be made beyond those made at Closing, and shall make
any such adjustments by appropriate  payments from Seller to Buyer or from Buyer
to Seller.  Following such additional adjustments,  no further adjustments shall
be made under this Article X.

                         Assumption and Indemnification

         Section 11.1. Seller's  Indemnification  Obligations.  Seller shall, on
the date of Closing, agree (and, upon delivery to Buyer of the Assignment, shall
be deemed to have agreed),  subject to the limitations and procedures  contained
in this Article XI and in Section 15.1,  following the Closing, to indemnify and
hold Buyer harmless from and against any and all claims,  obligations,  actions,
liabilities, damages or expenses (collectively,  "Buyer's Losses") (a) resulting
from any  misrepresentation or breach of any warranty,  covenant or agreement of
Seller contained in this Agreement or any certificate delivered by Seller at the
Closing,  or (b) relating to injuries (including death) to persons or damages to
property  (including  environmental  damage),  failure to make required payments
under the applicable leases governing the Oil and Gas Properties  arising out of
operations  prior to the Effective  Date, or the  obligations  of Seller arising
prior to the Effective Date under any of the contracts or agreements  assumed by
Buyer pursuant hereto.

         Section 11.2. Buyer's Indemnification Obligations.  Buyer shall, on the
date of Closing, agree (and, upon delivery to Buyer of the Assignment,  shall be
deemed to have agreed),  subject to the limitations and procedures  contained in
this Article XI and in Section  15.1,  following  the Closing,  to indemnify and
hold Seller harmless from and against any and all claims, obligations,  actions,
liabilities, damages, costs or expenses,  (collectively,  "Seller's Losses") (a)
resulting  from any  misrepresentation  or breach of any  warranty,  covenant or
agreement of Buyer contained in this Agreement or any  certificate  delivered by
Buyer at the Closing,  or (b) relating to injuries  (including death) to persons
or  damages  to  property  (including  environmental  damage),  failure  to make
required  payments  under  the  applicable  leases  governing  the  Oil  and Gas
Properties   arising  out  of  operations  after  the  Effective  Date,  or  the
obligations of Buyer arising after the Effective Date under any of the contracts
or agreements assumed by Buyer pursuant hereto.

         Section  11.3.  Net  Amounts.  Any  amounts  recoverable  by any  party
pursuant to this Article XI with  respect to any Buyer's Loss or Seller's  Loss,
as the case may be, shall be  increased by any net tax costs to the  indemnified
party (taxes  incurred with respect to any  indemnity  payment less tax benefits
resulting from the  circumstances  serving as the basis for such Buyer's Loss or
Seller's  Loss,  as the case may be) and shall be  decreased  by (i) any net tax
benefit to the indenified party (tax benefits less taxes incurred, as calculated
above),  and (ii) insurance  proceeds or other amounts  relating to such Buyer's
Loss or Seller's Loss, as the case may be, paid to such indemnified party by any
person (other than any affiliate of such indemnified  party) not a party to this
Agreement.

         Section 11.4. Notice of Claim. If  indemnification  pursuant to Section
11.1 or 11.2 is sought,  the party seeking  indemnification  (the  "Indemnitee")
shall give written notice to the  indemnifying  party of an event giving rise to
the obligation to indemnify,  describing in reasonable  detail the factual basis
for such claim, and shall allow the indemnifying party to assume and conduct the
defense  of the claim or action  with  counsel  reasonably  satisfactory  to the
Indemnitee,  and cooperate with the  indemnifying  party in the defense thereof;
provided,  however,  that the  omission to give such notice to the  indemnifying
party shall not relieve the  indemnifying  party from any liability which it may
have to the  Indemnitee,  except to the extent  that the  indemnifying  party is
prejudiced  by the failure to give such notice.  The  Indemnitee  shall have the
right to employ  separate  counsel to represent the Indemnitee if the Indemnitee
is advised by counsel that an actual conflict of interest makes it advisable for
the Indemnitee to be represented by separate counsel and the reasonable expenses
and fees of such separate counsel shall be paid by the indemnifying party.

         Section  11.5.   Indemnification   Exclusive  Remedy.   Indemnification
pursuant to the  provisions of this Article XI shall be the exclusive  remedy of
the parties hereto for any misrepresentation or breach of any warranty, covenant
or agreement contained in this Agreement or in any closing document executed and
delivered  pursuant  to the  provisions  hereof or  thereof,  or any other claim
arising out of the transactions contemplated by this Agreement.

         Section 11.6. No Assumption.  Notwithstanding  anything provided herein
to the contrary,  Buyer does not assume any  obligation or liability  whatsoever
arising out of or relating to the TGas Contracts,  to the extent such obligation
or liability is associated with Credit  Payments,  the Recourse Note, Tax Audits
(as  defined in the TGas  Contracts),  or other tax  issues,  and Seller  hereby
agrees to indemnify and hold Buyer harmless from and against any and all claims,
obligations,  actions,  liabilities,  damages, or expenses, including reasonable
attorney's or  consultant's  fees and expenses,  so arising,  whether  before or
after Closing.

                                  Casualty Loss

         In the  event of  damage by fire or other  casualty  to the  Properties
after the Effective  Date and prior to the Closing,  then this  Agreement  shall
remain in full force and effect,  and (unless  Buyer and Seller shall  otherwise
agree) in such event

         (a) as to  each  such  Property  so  damaged  which  is an Oil  and Gas
Property,  then, at Buyer's election,  either (i) such Property shall be treated
as if it had an Asserted Defect  associated  with it and the procedure  provided
for in Article 7 shall be applicable thereto, or (B) the Purchase Price will not
be  adjusted,  and if Seller  should be  entitled  to make any claims  under any
insurance  policy  with  respect  to such  damage,  Seller  shall,  at  Seller's
election,  either collect (and when  collected pay over to Buyer),  or assign to
Buyer, such claims, and

         (b) as to  each  such  Property  which  is  other  than  an Oil and Gas
Property, Seller shall, at Seller's election, either collect (and when collected
pay over to Buyer), or assign to Buyer, any and all insurance claims relating to
such loss,  and Buyer  shall take title to the  Property  affected  by such loss
without reduction of the Purchase Price.

                              Miscellaneous Matters

         Section  15.1.   Survival  of  Provisions.   All   representations  and
warranties of Seller or Buyer  contained in this  Agreement,  any Schedule or in
any certificate  delivered at the Closing shall survive the Closing for a period
of two years from the Closing Date (the "Indemnification Period"). Any claim for
indemnification  for a breach of  representation  or  warranty  pursuant to this
Agreement  must be made prior to the expiration of the  Indemnification  Period.
Notwithstanding  the  foregoing,  (i) the  obligation  of each  party  hereto to
indemnify  any other party hereto shall  continue  after the  expiration  of the
Indemnification  Period  with  respect  to any  matter  which the party  seeking
indemnity  hereunder  shall  have  given the other  party  written  notice of as
provided herein prior to the expiration of the Indemnification  Period, and (ii)
the  obligations  of  Seller  to  indemnify  Buyer  under  Section  11.6 of this
Agreement  shall  continue  until the  expiration  of all  applicable  state and
federal statutes of limitation that may apply to any party having an interest in
the TGas Contracts.

         Section  15.2.  Further  Assurances.  After the  Closing,  Seller shall
execute and deliver,  and shall  otherwise  cause to be executed and  delivered,
from time to time, such further instruments,  notices, division orders, transfer

may be  reasonably  necessary to more fully and  effectively  grant,  convey and
assign the Properties to Buyer.

         Section 15.3.  Binding  Effect;  Successors and Assigns.  The Agreement
shall be  binding on the  parties  hereto and their  respective  successors  and
permitted assigns. Neither party shall have the right to assign its rights under
this  Agreement,  without  the prior  written  consent of the other  party first
having been obtained.

delivery to Buyer of the  Assignments),  Buyer shall  succeed to the position of
Seller with respect to all gas imbalances.  As a result of such succession Buyer
shall (i) be  entitled to receive any and all  benefits,  including  payments of
proceeds of production in excess of amounts which it would otherwise be entitled
to produce and  receive by virtue of  ownership  of the Oil and Gas  Properties,
which Seller would have been entitled to receive by virtue of such positions and
(ii) shall be  obligated  to suffer any  detriments  (whether the same be in the
form of  obligations  to deliver  production  which  would have  otherwise  been
attributable  to its ownership of the Oil and Gas Properties  without  receiving
full payment  therefor,  or be in the form of the  obligation to make payment in
cash)  which  Seller  would  have  been  obligated  to  suffer by virtue of such
positions.

         Section  15.5.  Expenses.  Each party  shall bear and pay all  expenses
incurred  by  it  in  connection  with  the  transaction  contemplated  by  this
Agreement.

understanding  of the parties  hereto with respect to subject  matter hereof and
supersedes all prior agreements,  understandings,  negotiations, and discussions
among the parties with respect to such subject matter. Time is of the essence in
this Agreement.

         Section 15.7.  Public  Statements.  Seller and Buyer shall consult with
each  other  with  regard to all  publicity  and other  releases  at or prior to
Closing concerning this Agreement and the transactions  contemplated hereby and,
except as required by applicable law or the  applicable  rules or regulations of
any governmental body or stock exchange, neither party shall issue any publicity
or other release without the prior consent of the other party.

         Section 15.8.  Injunctive  Relief.  The parties hereto  acknowledge and
agree that irreparable  damage would occur in the event any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of the provisions
of this Agreement,  and shall be entitled to enforce specifically the provisions
of this Agreement, in any court of the United States or any state thereof having
jurisdiction,  in  addition  to any other  remedy to which  the  parties  may be
entitled under this Agreement or at law or in equity.

         Section 15.9.  Amendments.  This  Agreement  may be amended,  modified,
supplemented,  restated or discharged (and provisions hereof may be waived) only
by an instrument in writing signed by the party against whom  enforcement of the
amendment,  modification,  supplement,  restatement  or discharge (or waiver) is
sought.

         Section 15.10.  Governing Law. This Agreement  shall be governed by and
construed in accordance with the laws of the State of Texas.

         Section  15.11.  Counterparts.   This  Agreement  may  be  executed  in

         Section 15.12.  Arbitration.  Any dispute arising out of or relating to
this  Agreement,  any schedule,  certificate or other document  delivered by any
party  in  connection  with  this  Agreement  or  incident  to the  transactions
contemplated  hereby  or  thereby  or the  breach,  inaccuracy,  termination  or
validity  hereof or thereof  or  otherwise  arising  out of or  relating  to the
transactions  contemplated hereby and thereby, or any other agreement among them
or between any of them,  whether  entered into prior to, on or subsequent to the
date of this  Agreement or those arising under any federal,  state or local law,
regulation  or  ordinance,   shall  be  determined  by  binding  arbitration  in
accordance with the then current  Commercial  Arbitration  Rules of the American
Arbitration Association. If the amount in controversy in the arbitration exceeds
Two Hundred Fifty Thousand Dollars ($250,000), exclusive of interest, attorneys'
fees and costs, or if a single neutral  arbitrator  cannot be agreed upon within
thirty (30)  calendar  days after a dispute has arisen which is to be decided by
arbitration,  the arbitration shall be conducted by a panel of three (3) neutral
arbitrators.  Otherwise,  the arbitration shall be conducted by a single neutral
arbitrator.  The parties shall endeavor to select neutral  arbitrators by mutual
agreement.  If such agreement cannot be reached within thirty (30) calendar days
after a dispute  has arisen  which is to be decided by  arbitration,  each party
shall select its own neutral arbitrator within 15 days of the expiration of such
30-day period and the two neutral  arbitrators  so selected shall select a third
neutral arbitrator within 10 days of the expiration of such 15-day period. The 3
persons thus selected shall be the  arbitrators for such  arbitration.  If three
(3)  arbitrators  are selected,  the  arbitrators  shall elect a chairperson  to
preside at all meetings and  hearings.  If a dispute is to be resolved by a sole
arbitrator  in  accordance  with the terms  hereof,  or if the  dispute is to be
resolved by a panel of three (3) arbitrators as provided hereinabove,  then such
sole arbitrator or the chairperson of such panel, as the case may be, shall be a
member of a state bar engaged in the  practice of law in the United  States or a
retired  member of a state or the federal  judiciary in the United  States.  The
award of the  arbitrator(s)  shall require a majority of the  arbitrators in the
case of a panel of arbitrators, shall be in writing and reasoned, shall be based
on the evidence admitted and the substantive law of the State of Texas and shall
contain an award for each issue and counterclaim. The award shall be made within
thirty (30) days  following the close of the final hearing and the filing of any
post  hearing  briefs  authorized  by  the  arbitrator(s).   The  award  of  the
arbitrator(s)  shall be final and binding on the parties  hereto and the subject
matter.  Judgment upon the award rendered by the arbitrator(s) may be entered by
any court  having  jurisdiction.  The place of  arbitration  shall be in Dallas,
Texas.  Each party  shall be  entitled  to inspect and obtain a copy of relevant
documents  in  the  possession  or  control  of the  other  party  and  to  take
depositions  of  the  other  parties'  employees,  agents,  representatives  and
witnesses  (including  expert  witnesses).   All  such  discovery  shall  be  in
accordance  with  procedures  approved by the  arbitrator(s).  Unless  otherwise
provided  in the award,  each party shall bear its own costs of  discovery.  All
discovery  shall be expedited,  consistent with the nature and complexity of the
claim or dispute and  consistent  with fairness and justice.  The  arbitrator(s)
shall have the power to compel any party to comply  with  discovery  requests of
the other parties and to issue binding orders relating to any discovery  dispute
which shall be enforceable in the same manner as awards.  The arbitrator(s) also
shall  have the  power to  impose  sanctions  for  abuse or  frustration  of the
arbitration  process,  including without limitation,  the refusal to comply with
orders of the arbitrator(s) relating to discovery and compliance with subpoenas.
Each of the parties hereto hereby irrevocably submits to the jurisdiction of the
courts of the State of Texas for entry of any arbitration  decision or to obtain
any  preliminary  relief  which may be  necessary  and  hereby  consents  to the
enforcement by such courts of any award rendered in such arbitration.

         Section III.3. Request for Additional Capital  Contributions of Limited
Partner.

        (a)  Subject  to this  Section  3.3 and the other  terms and  provisions
hereof, the General Partner may request  additional  Capital  Contributions from
the Limited  Partner to be used  exclusively  for the  payment of its  allocated
share  (pursuant to Section 4.1) of (i) Capital  Costs of the type  described in
clause (a) of the definition  thereof,  (ii) Capital Costs of the type described
in  clause  (b) of the  definition  thereof,  (iii)  Capital  Costs  of the type
described in clause (c) of the  definition  thereof,  (iv) Capital  Costs of the
type described in clause (d) of the definition thereof, (v) Capital Costs of the
type  described in clause (e) of the definition  thereof,  (vi) Capital Costs of
the type described in clause (f) of the definition thereof and (vii) Acquisition
Costs under the  circumstances  described in Section 5.3. Each of the categories
of expenditures described in clauses (i), (ii), (iii), (iv), (v), (vi) and (vii)
of this  Section  3.3(a) may  include  such  contingent  amounts as the  General
Partner in good faith shall determine to be appropriate under the circumstances.

        (b)  Requests  for  additional  Capital  Contributions  pursuant to this
Section  3.3 shall be made by the  General  Partner and agreed to by the Limited
Partner  separately  with  respect to each of the Capital  Costs or  Acquisition
Costs specified in subsection (a) above.  Requests  pursuant to this Section 3.3
shall not be made more often than  quarterly  each year (i) except for  requests
pursuant to clause (vii) of subsection  (a) above,  (ii) except in the event the
request is  attributable  to a proposal  from an unrelated  third party or (iii)
unless an  emergency  or some other  urgent need for funds exist  outside of the
reasonable  control of the General Partner.  Payments of any additional  Capital
Contributions  agreed to be made by the Limited Partner pursuant to this Section
3.3 shall be requested by the General Partner and made by the Limited Partner in
the manner provided for in Section 3.5(d).


                                       15
<PAGE>
        (c) Notice of any request for additional  Capital  Contributions made by
the General  Partner shall be in writing and sent to the Limited  Partner at its
address as  provided  in Section  12.1.  With  respect to the  category of costs
described in clauses (i), (ii),  (iii),  (iv),  (v) and (vi) of Section  3.3(a),
each request shall cover all of the Capital Costs intended to be incurred during
the next three  months  (and with  respect to any  Partnership  well or Enhanced
Recovery Operation or facility, the costs estimated to be incurred in connection
with such well or operation or facility).  With respect to the category of costs
described in clause (vii) of Section  3.3(a),  each  request  shall  contain the
information specified in Section 5.3. Each such request shall also set forth (i)
the date by  which  the  Limited  Partner  must  elect  in  writing  to make the
requested additional Capital Contributions, which date shall not be less than 30
days from the date the General  Partner  mails or sends such  request,  unless a
shorter  period  is  provided  to  the  General  Partner  under  any  applicable
"authority  for  expenditure"  submitted  by an operator  other than the General
Partner or an  Affiliate,  in which  event  such  shorter  period  shall also be
applicable to the election  period of the Limited  Partner  (provided that in no
event  shall  such  shorter  period be less than 15 days),  (ii) the  purpose or
purposes  for  which  the   proceeds  of  the   requested   additional   Capital
Contributions are to be used, (iii) to the extent practicable,  a summary of the
pertinent  geological  data  relating to each well or operation  with respect to
which  the  proceeds  that  are  requested  are  to be  expended  and  financial
projections  with  respect  to  the  expenditure  of  such  additional   Capital
Contributions  and the revenue  projected  to be received  therefrom  and (iv) a
summary of the action that the General  Partner  anticipates  it will take under
Section 3.3(d) and any  applicable  operating  agreement if the Limited  Partner
does not elect to make  such  requested  additional  Capital  Contributions.  In
connection with any request  pertaining to an Enhanced Recovery  Operation,  the
General Partner shall endeavor to confine such request to the extent possible in
accordance with generally  accepted industry standards to those matters or items
which  should be  conducted  in  conjunction  with each other.  Thereafter,  the
General  Partner shall promptly  furnish to the Limited  Partner such additional
information  concerning  the use and  application  of the  requested  additional
Capital  Contributions as the Limited Partner shall reasonably  request.  In the
event  the  Limited  Partner  does  not  elect to pay all of the  categories  of
requested additional Capital Contributions (or operations or acquisitions within
a  given  category),  it may  elect  to pay  all  of the  Capital  Contributions
requested to be used for any of the remaining  categories of costs designated in
the General Partner's request as provided above (or, as to a given category, the
costs associated with any other operation or acquisition  within such category).
The General  Partner shall not use any Capital  Contributions  received from the
Limited  Partner  pursuant to this Section 3.3 and designated for payment of one
category of costs to pay any other category of costs.

        (d) If the  Limited  Partner  declines  to make any  additional  Capital
Contributions (or any part thereof) requested by the General Partner or fails to
give timely notice to the General  Partner  pursuant to a request for additional
Capital  Contributions  made pursuant to Section 3.3(a), the General Partner may
elect to take any action  specified  in  paragraphs  (1)  through (6) below with
respect  to each  Lease,  Partnership  well,  operation  or project to which the
request pertains, if appropriate:

                                       16
<PAGE>

                  (1) With  respect to the  acquisition  of Leases  pursuant  to
        Section  5.3,  the General  Partner or its  Affiliates  may  purchase or
        retain  for its or their own  account  the Leases  not  acquired  by the
        Partnership.

                  (2) The  General  Partner  may cause the  Partnership  (to the
        extent it can do so under any applicable operating agreement) to abandon
        the operation or project,  in which event all costs (if any)  thereafter
        incurred in  abandoning  the  operation or project shall be borne by the
        Partnership.

                  (3) The  General  Partner may cause the  Partnership  to sell,
        farm-out or  otherwise  dispose of the well or Lease (or the  applicable
        part thereof) to which such operation or project pertains to any person;
        provided,  however, that no such sale, farm-out or other disposition may
        be made to the  General  Partner or any  Affiliate  thereof  without the
        prior written consent of the Limited Partner.

                  (4) In the  event a well  or  Lease  to  which  such  proposed
        operation or project  pertains is subject to an  operating  agreement to
        which one or more third persons (which are not Affiliates of the General
        Partner) are parties,  the General  Partner may cause the Partnership to
        elect not to  participate  in the proposed  operation  and to assume the
        status of a  "non-consenting  party"  under  such  operating  agreement;
        provided,  however,  that  neither  the  General  Partner nor any of its
        Affiliates  shall be  permitted  to pay or shall  pay the  Partnership's
        non-consenting  share of  costs or  expenses  or any part  thereof  with
        respect to such operation or project under such operating agreement.

                  (5) With respect to any well, the General  Partner may pay the
        requested additional Capital  Contributions the Limited Partner declined
        to pay,  and the amount so paid by the General  Partner  with respect to
        such well  shall be  credited  to a  separate  account,  which  separate
        account shall be charged and credited as follows:

                           (x)  Subject  to  subparagraph  (y) of  this  Section
                  3.3(d)(5),  all of the  Limited  Partner's  share of costs and
                  expenses  with  respect  to such well shall be charged to such
                  separate account,  and such separate account shall be credited
                  with the Limited  Partner's  share of revenues  from such well
                  (after deducting all production, severance, excise and similar
                  taxes relating  thereto).  Until the total amount  credited to
                  such  separate   account   equals  the  amount   specified  in
                  subparagraph  (y) of this  Section  3.3(d)(5)  with respect to
                  such well,  the General  Partner shall be allocated all of the
                  costs and expenses charged to such separate  account,  and the
                  Limited  Partner shall be deemed to have  relinquished  to the
                  General Partner,  and the General Partner shall have allocated
                  to it and be entitled to receive, all of the revenues credited
                  to such separate account.

                           (y) If,  as and when the  total  amount  of  revenues
                  received by and credited and allocated to the General  Partner
                  under  subparagraph (x) of this Section  3.3(d)(5) shall equal
                  the sum of the following to the extent they are appropriate:

                                       17
<PAGE>

                                     a.  300%  of the  amount  charged  to  such
                           separate account for Capital Costs; and

                                     b.  100%  of the  amount  charged  to  such
                           separate  account for Lease  Operating and Production
                           Costs;

                  no  further  amounts  shall be  charged  or  credited  to such
                  separate  account,  and the  Limited  Partner's  share  of all
                  revenues and costs and expenses thereafter arising or accruing
                  with  respect to such well  shall be  allocated,  charged  and
                  credited to the Limited Partner.

                  (6) The General  Partner may take such other actions as may be
         mutually agreed upon by the Partners.

        Section III.4. Reduced Capital  Contributions of Limited Partner. In the
event the Partnership or the General Partner  properly  retains a portion of the
Limited  Partner's  share of Partnership  revenues for the purpose of paying any
Acquisition  Costs,  Capital Costs, Hedge Costs, or Organization Costs allocated
to the Limited  Partner  hereunder in accordance with Section 4.4, the amount so
retained  and not  distributed  shall  reduce  pro tanto the  amount of  Capital
Contributions the Limited Partner is required to thereafter make.

        Section III.5.     Payments of Capital Contributions.

        (a) The Limited Partner shall pay the Capital Contribution referenced in
Section  3.2(a) on the Delivery  Date and, if and to the extent the  Partnership
owes the  Seller  an  amount  under  Article X of the  Purchase  Agreement  as a
post-closing  adjustment,  on the date on which such post-closing  adjustment is
due under the Purchase Agreement.

        (b) The Limited Partner shall pay the Capital  Contributions  referenced
in Section 3.2(b) within five business days of the Limited  Partner's receipt of
a request from the General Partner for such purpose.

        (c) The Limited Partner shall pay the Capital  Contributions  referenced
in Section 3.2(c)  promptly after receipt of a request from the General  Partner
for such purpose.

        (d) Except as otherwise  provided in subsections (a), (b) and (c) above,
the Limited Partner shall pay its Capital  Contributions monthly upon request by
the  General  Partner in such  amounts as are  required  to pay its share of all
costs and expenses properly  allocated to it hereunder.  The General Partner may
request on a monthly  basis  additional  payments of the  Capital  Contributions
agreed to be made by the Limited Partner for the Limited  Partner's share of (i)
all costs and  expenses  estimated  to have been  and/or to be  incurred  by the
Partnership  during that  calendar  month except those for which  advances  have
previously  been made or for which payment will be made from another  source and
(ii) those costs and expenses estimated to be incurred by the Partnership during
the next succeeding  calendar  month.  Each monthly request for payment shall be
adjusted  to the  extent  the  Limited  Partners'  cumulative  share  of  actual


                                       18
<PAGE>

Partnership  disbursements for the preceding calendar month's costs and expenses
is either greater or less than the amounts previously contributed by the Limited
Partner for such  purpose.  Any  request  for payment by the Limited  Partner of
Capital  Contributions  shall be in  writing  and  shall set forth (1) the type,
nature or items of Partnership  costs or expenses for which such payment will be
used by the Partnership,  including  without  limitation a division of the costs
and expenses as  contemplated in clauses (i) and (ii) of this Section 3.5(d) and
the  adjustment  referred to in this Section  3.5(d),  (2) the net amount of the
Capital  Contributions  to be paid by the  Limited  Partner  and (3) the date by
which payment of such Capital  Contributions shall be received,  which shall not
be less than five  business  days from the date the  notice is  received  by the
Limited Partner.

        (e) Payments by the Limited Partner of its Capital  Contributions  shall
be made by wire transfer of  immediately  available  funds to the  Partnership's
account as  designated by the General  Partner by notice to the Limited  Partner
pursuant to Section 12.1.

        (f)  Any  additional  Capital  Contributions  agreed  to be  made by the
Limited Partner  pursuant to Section 3.3 may be requested only during the period
commencing  on the date they were  originally  requested by the General  Partner
under  Section 3.3 and ending  three months  thereafter  with respect to Capital
Contributions to be used to pay Acquisition Costs and six months thereafter with
respect to Capital  Contributions to be used to pay Capital Costs and shall only
be  requested  for and expended on the  respective  purposes for which they were
agreed to be made.

        Section III.6.     Non-payment of Capital Contributions.

        (a)  Except  as  otherwise  provided  in  the  following  sentence,  the
Partnership  shall  have the  right to pursue  the  remedies  described  in this
Section 3.6 and any remedy  existing at law or in equity for the  collection  of
the unpaid amount of the Capital Contributions agreed to be made in Sections 3.1
and 3.2 or hereafter agreed to be made in accordance with Section 3.3, including
without  limitation the prosecution of a suit against a defaulting  Partner.  In
the  event  of a  default  by a  Partner  of  its  obligation  to  make  Capital
Contributions  with respect to its allocable share hereunder of Hedge Costs, the
provisions  of  subsection  (d)  below  shall  be the  exclusive  remedy  of the
Partnership and the other Partner.

        (b) In the event that the Limited  Partner fails or refuses to make when
due its share of Capital  Contributions,  the General  Partner shall be entitled
(but  shall  not  be  obligated)  to  make  such  Capital  Contributions  to the
Partnership  which the Limited  Partner is  obligated  to make and the amount so
advanced  shall be  treated  as a loan to the  Limited  Partner  and shall  bear
interest  from the date of such advance at a rate equal to the Agreed Rate.  The
General Partner shall notify the Limited Partner of any such advance and request
payment by the Limited Partner of the amount so advanced, together with interest
thereon from the date of the advance. If the Limited Partner fails or refuses to
pay to the  General  Partner  the amount so  advanced,  together  with  interest
thereon  from the date of the advance,  and if such failure or refusal  persists
for a period of 30 days following notice from the General Partner to the Limited
Partner (such occurrence being called herein an "Event of Default"), the General
Partner shall be entitled to proceed under this Section  3.6(b).  In addition to
the  rights  in  Section  3.6(a),  the  Limited  Partner  hereby  grants  to the
Partnership a lien upon and security interest in the Limited Partner's  interest


                                       19
<PAGE>

in the Partnership  and in or to all assets  attributable to and proceeds of and
from such  interest in the  Partnership  to secure the payment of  contributions
required under this  Agreement,  and authorizes  the General  Partner,  upon the
occurrence  of an  Event  of  Default,  if  it  elects  to  proceed  under  this
alternative,  to foreclose such lien or security interest in any manner provided
for by the laws of the  State  of  Texas  for the  foreclosure  of such  lien or
security interest  (including without limitation the exercise of the rights of a
secured party under the Texas Uniform  Commercial  Code). If the General Partner
elects this  alternative,  the Limited Partner shall be liable for all costs and
expenses of the General  Partner in  instituting  and  prosecuting  such suit or
foreclosing such lien or security interest,  including all reasonable attorneys'
fees expended in connection  therewith.  The Limited  Partner hereby agrees that
the General  Partner may file one or more financing  statements  with respect to
the security interest granted hereby in order to perfect such security interest,
and the Limited  Partner hereby agrees to execute such  financing  statements at
the request of the General Partner.  The Limited Partner further hereby appoints
the General Partner as its agent and attorney-in-fact for the purpose of signing
and filing any such financing  statements,  which appointment is coupled with an
interest  and  expressly  made  irrevocable.  In  the  event  of a  non-judicial
foreclosure,  the proceeds of the disposition of the Partnership interest of the
Limited  Partner  shall be applied as  follows:  (i)  first,  to the  reasonable
expenses incurred by the Partnership in collecting such proceeds; and (ii) next,
to the satisfaction of the portion of the Limited  Partner's  contribution  then
due. The Limited  Partner  shall be liable for any  deficiency,  and the General
Partner shall account to the Limited  Partner for any surplus.  Any purchaser of
the Limited  Partner's  interest in the Partnership shall assume the obligations
of the Limited  Partner  under this  Agreement and shall succeed to the right of
the  Limited  Partner as to the  allocation  of profits and losses of, and as to
distributions from, the Partnership  thereafter.  The defaulting Limited Partner
hereby  grants the General  Partner an  irrevocable  special  power of attorney,
coupled with an interest,  which shall survive the dissolution,  bankruptcy,  or
legal  disability of the Limited Partner,  to take all actions  necessary on its
behalf to sell,  assign or  transfer  the  Partnership  interest  of the Limited
Partner to such person or persons as shall acquire such Partnership  interest as
provided  in this  Section  3.6(b)  should an Event of Default be deemed to have
occurred  with  respect to the  Limited  Partner.  In the event that the General
Partner  elects  to  foreclose  upon  the  Limited  Partner's  interest  in  the
Partnership,  the Partners  agree that 30 days prior notice shall be  reasonable
notice of any proposed public or private  foreclosure sale.  Notwithstanding the
foregoing,  the General  Partner  shall not  foreclose  upon the interest of the
Limited  Partner in the  Partnership  if the Event of Default giving rise to the
exercise of remedies  under this  Section 3.6 arises out of a bona fide  dispute
regarding the interpretation or implementation of this Agreement.

        (c) The Partnership may retain any revenues  otherwise  distributable to
the Limited Partner  pursuant to this Agreement in an amount equal to the amount
the Limited Partner failed or refused to contribute as required  pursuant to the
terms of this  Agreement,  together with interest on such past-due  amounts at a
rate equal to the Agreed Rate. Any amount so withheld  shall be deemed,  for all
purposes of this Agreement, to have been distributed to the Limited Partner and,
other than that portion of such amounts representing interest, be deemed to have
been  recontributed by the Limited Partner to the capital of the Partnership for
the purposes for which contributions were initially requested. If any dispute as
to whether  an Event of Default  existed  is  resolved  in favor of the  Limited


                                       20

Partner,  then the General Partner shall pay to the Partnership for distribution
to the  Limited  Partner  an amount  equal to any  amounts  wrongly  paid by the
Limited  Partner to the  Partnership  which should have instead been paid to the
Partnership  by  the  General  Partner,   or  any  amounts  distributed  by  the
Partnership to the General Partner instead of the Limited Partner, in connection
with such Event of Default together with interest thereon at a rate equal to the
Agreed Rate, and all costs and expenses of the Limited Partner in resolving such
dispute,  including all attorneys'  fees expended in connection  therewith.  The
General  Partner  shall give notice of its election of the  alternatives  listed
above to the Limited Partner,  and if the General Partner elects the alternative
provided under Section 3.6(a) and/or Section  3.6(b),  the General Partner shall
be free at any time also to proceed under this Section 3.6(c).

        (d0 If a Partner  (the  "Defaulting  Partner")  fails or refuses to make
Capital Contributions to the Partnership hereunder when due to pay its allocable
share  hereunder  of  Hedge  Costs  and the  other  Partner  (the  "Contributing
Partner") in the Defaulting Partner's stead makes such Capital  Contributions to
the  Partnership,  then the terms and provisions of this Section 3.6(d) shall be
operative.  Specifically,  in the instance  described  above,  the  Contributing
Partner  may  treat  the  payment  by it of  the  Defaulting  Partner's  Capital
Contributions as Capital  Contributions from the Contributing  Partner, in which
case  the  Contributing  Partner  shall  be  entitled  to  receive  all  of  the
distributions  that would otherwise be paid to the Defaulting  Partner hereunder
until that point in time at which the  Contributing  Partner has  received  from
such  distributions  an  amount  equal  to 300%  of the  amount  of the  Capital
Contributions  made by the  Contributing  Partner  in the  Defaulting  Partner's
stead;  provided,  however,  that if this  option  is  elected,  the  Defaulting
Partner's share of the Hedge Costs paid with such Capital Contributions, and any
deductions or losses relating  thereto for state or federal income tax purposes,
shall be allocated to the Contributing  Partner; and provided further,  that the
Defaulting  Partner's  share of  Partnership  revenues,  and any  income or gain
relating thereto for state or federal income tax purposes, shall be allocated to
the Contributing Partner until the revenues so allocated equal the distributions
to be made to the Contributing Partner under this paragraph (ii).

        Section III.7.     Interest on and Return of Capital Contributions.

        (a) No interest shall accrue on any  contributions to the capital of the
Partnership;  however,  all interest which accrues on Partnership funds shall be
allocated and credited to the Partners in accordance with Section 4.2.

        (b) No Partner shall have the right to withdraw or be repaid any capital
contributed  by such Partner except (a) as provided in Sections 10.2 and 10.3 or
(b) in the instance when the  Partnership  receives a return of cash funds under
the Purchase  Agreement due to an adjustment to the Adjusted  Purchase Price (in
which  event  the  General   Partner  shall  cause  the  Partnership  to  refund
immediately to the Limited Partner its allocable share of such cash funds).

         Section IV.1.  Allocation of Costs and Expenses.  Except as provided in
Sections  3.3 and 3.6,  all  costs  and  expenses  of the  Partnership  shall be
allocated and charged to the Partners as follows:

        (a) All Catastrophe Costs incurred by the Partnership shall be allocated
100% to the General Partner.

        (b) The  Adjusted  Purchase  Price shall be  allocated 1% to the General
Partner and 99% to the Limited Partner.

        (c) All other costs and  expenses of the  Partnership  not  specifically
allocated above shall be allocated (i) to the General Partner in accordance with
its GP Sharing  Percentage  for the month in which such costs and  expenses  are
paid  and  (ii)  to the  Limited  Partner  in  accordance  with  its LP  Sharing
Percentage for the month in which such costs and expenses are paid.

        Section IV.2.      Allocation of Revenues.

        (a0 Except as  provided  in Sections  3.3 and 3.6,  all  revenues of the
Partnership  (which  shall not include  Capital  Contributions  and loans to the
Partnership) shall be allocated and credited to the Partners as follows:

                  (i) Insurance  proceeds,  to the extent not otherwise expended
        by the Partnership to preserve,  protect or replace Partnership property
        in the event of an accident or other  occurrence  or to pay  Partnership
        liabilities  or other  obligations  arising  from an  accident  or other
        occurrence,  shall be allocated  between the Partners in the same manner
        as the revenues  from the sale of the  property to which such  insurance
        proceeds related would be allocated under this Section 4.2. The proceeds
        of any Catastrophe Costs Recovery shall be allocated 100% to the General
        Partner.

                  (ii) All  revenues  used to repay any  principal,  interest or
        other  amounts  owing with  respect  to any  Partnership  borrowings  or
        indebtedness  shall be allocated to the Partners in the same proportions
        as the costs and expenses paid with such borrowings or indebtedness were
        allocated to the Partners  (and,  with  respect to any  indebtedness  to
        which any property acquired by the Partnership is subject at the time of
        its  acquisition,  in the same  proportions as costs are allocated under
        Section   4.1(b)  at  the  time  such   property   is  acquired  by  the
        Partnership).

                  (iii)  After  making the  allocation  provided  for in Section
        4.2(a)(ii) and taking into account the revenues allocated  therein,  all
        additional  revenues  resulting  from the sale or other  disposition  of
        Depletable Property (as defined in Section 4.3(b)) shall be allocated to
        the Partners in the same  percentages  as the costs of the property sold
        were  allocated,  to the extent such  revenues  constitute a recovery of
        Simulated  Basis of such Depletable  Property,  up to an amount equal to
        the  Partnership's  Simulated Basis in such property at the time of such
        sale or disposition.  Thereafter,  revenues resulting from any such sale
        or disposition shall be allocated to the Partners in a manner which will


                                       22
<PAGE>

        cause the aggregate of all revenues  allocated to the Partners from such
        sale or disposition (to the extent  possible) to equal the amounts which
        would have been  allocated  under  Section  4.2(a)(iv) in the absence of
        this Section 4.2(a)(iii).

                  (iv) All other revenues of the  Partnership  not  specifically
        allocated  above  shall  be  allocated  (A) to the  General  Partner  in
        accordance  with its GP Sharing  Percentage  for the month in which such
        revenues are received and (B) to the Limited  Partner in accordance with
        its LP  Sharing  Percentage  for the month in which  such  revenues  are
        received.

        (b) All dry hole and bottom hole and similar  contributions shall not be
considered  to be revenues  hereunder but shall be applied to reduce the Capital
Costs of the respective wells to which they relate.

        Section  IV.3.  Income Tax  Allocations.  Except as  otherwise  provided
herein, for purposes of any applicable  federal,  state or local income tax law,
rule or regulation items of income,  gain,  deduction,  loss,  credit and amount
realized shall be allocated to the Partners as follows:

        (a) Income from the sale of oil or gas  production  and any credits,  if
any,  allowed by Section 29 of the Internal  Revenue Code relating thereto shall
be allocated in the same manner as revenue  therefrom is allocated  and credited
pursuant to Section 4.2.

        (b) Cost and percentage depletion deductions and the gain or loss on the
sale or other  disposition of property the  production  from which is subject to
depletion  (herein  sometimes  called  "Depletable  Property") shall be computed
separately by the Partners rather than the Partnership.  For purposes of Section
613A(c)(7)(D) of the Internal Revenue Code, the Partnership's  adjusted basis in
each  Depletable  Property  shall be allocated to the Partners in  proportion to
each Partner's respective share of the costs and expenses which entered into the
Partnership's  adjusted  basis  for each  Depletable  Property,  and the  amount
realized on the sale or other  disposition of each Depletable  Property shall be
allocated to the Partners in proportion to each  Partner's  respective  share of
the revenue from the sale or other  disposition of such property provided for in
Section  4.2(a)(iii)  or Section  4.2(a)(iv),  as  applicable.  For  purposes of
allocating  amounts realized upon any such sale or disposition  which are deemed
to be  received  for  federal  income  tax  purposes  and  are  attributable  to
Partnership  indebtedness or  indebtedness  to which the Depletable  Property is
subject at the time of such sale or disposition, such amounts shall be allocated
in the same  manner  as  Partnership  revenues  used for the  repayment  of such
indebtedness would have been allocated under Section 4.2(a)(ii).

        (c) Items of deduction,  loss and credit not  specifically  provided for
above  (other  than  loss  from  the sale or other  disposition  of  Partnership
property),  including depreciation,  cost recovery and amortization  deductions,
shall be  allocated  to the  Partners  in the same  manner  that the  costs  and
expenses of the Partnership that gave rise to such items of deduction,  loss and
credit were allocated pursuant to Section 4.1.

                                       23
<PAGE>

        (d0 Gain from the sale or other disposition of Partnership property that
is not  specifically  provided for above shall be allocated to the Partners in a
manner which  reflects each  Partner's  allocable  share of the revenue from the
sale of the Partnership  property provided for in Section 4.2, and loss from the
sale or other  disposition  of  Partnership  property  that is not  specifically
provided for above shall be allocated to the Partners in a manner which reflects
each  Partner's  allocable  share of the costs and  expenses of the  Partnership
property provided for in Section 4.1.

        (e) All recapture of income tax  deductions  resulting  from the sale or
other disposition of Partnership property shall, to the maximum extent possible,
be  allocated  to the  Partner  to whom the  deduction  that  gave  rise to such
recapture was  allocated  hereunder to the extent that such Partner is allocated
any gain from the sale or other disposition of such property.

        (f) Income resulting from the Partnership's  receipt of dry hole, bottom
hole or similar contributions shall be allocated in the same manner as the costs
to which they were applied were allocated.

        (g) Any  other  items of  Partnership  income  or gain not  specifically
provided  for above shall be  allocated  in the same manner as the revenue  that
resulted in such income or gain is allocated  and  credited  pursuant to Section
4.2.

         (h) Notwithstanding any of the foregoing provisions of this Section 4.3
to the contrary:

                  (i) If during any fiscal  year of the  Partnership  there is a
        net increase in Minimum Gain attributable to a Partner  Nonrecourse Debt
        that gives rise to Partner Nonrecourse Deductions,  each Partner bearing
        the  economic  risk of loss for such Partner  Nonrecourse  Debt shall be
        allocated  items of  Partnership  deductions  and  losses  for such year
        (consisting  first of cost  recovery  or  depreciation  deductions  with
        respect to property that is subject to such Partner Nonrecourse Debt and
        then, if necessary,  a pro rata portion of the Partnership's other items
        of  deductions  and  losses,  with any  remainder  being  treated  as an
        increase in Minimum Gain attributable to Partner Nonrecourse Debt in the
        subsequent  year) equal to such Partner's  share of Partner  Nonrecourse
        Deductions,   as  determined  in  accordance  with  applicable  Treasury
        Regulations.

                  (ii) If for any fiscal year of the Partnership  there is a net
        decrease  in  Minimum  Gain  attributable  to  Partnership   Nonrecourse
        Liabilities, each Partner shall be allocated items of Partnership income
        and gain for such year (consisting  first of gain recognized,  including
        Simulated Gain, from the disposition of Partnership  property subject to
        one or more Partnership  Nonrecourse Liabilities and then, if necessary,
        a pro rata portion of the Partnership's  other items of income and gain,
        and if necessary, for subsequent years) equal to such Partner's share of
        such net decrease (except to the extent such Partner's share of such net
        decrease  is  caused  by a change in debt  structure  with such  Partner
        commencing  to bear the  economic  risk of loss as to all or part of any
        Partnership  Nonrecourse  Liability  or  by  such  Partner  contributing
        capital  to the  Partnership  that  the  Partnership  uses  to  repay  a
        Partnership  Nonrecourse  Liability),  as determined in accordance  with
        applicable Treasury Regulations.

                                       24
<PAGE>


                  (iii) If for any fiscal year of the Partnership there is a net
        decrease in Minimum Gain  attributable  to a Partner  Nonrecourse  Debt,
        each Partner shall be allocated items of Partnership income and gain for
        such year  (consisting  first of gain  recognized,  including  Simulated
        Gain,  from the disposition of Partnership  property  subject to Partner
        Nonrecourse  Debt,  and then,  if  necessary,  a pro rata portion of the
        Partnership's  other  items of income and gain,  and if  necessary,  for
        subsequent  years)  equal to such  Partner's  share of such net decrease
        (except to the  extent  such  Partner's  share of such net  decrease  is
        caused  by a change in debt  structure  or by the  Partnership's  use of
        capital  contributed by such Partner to repay Partner  Nonrecourse Debt)
        as determined in accordance with applicable Treasury Regulations.

        (i) The General Partner shall use all reasonable  efforts to prevent any
allocation  or  distribution  from  causing a negative  balance  in the  Limited
Partner's Adjusted Capital Account.  Consistent  therewith,  and notwithstanding
any of the foregoing provisions of this Section 4.3 to the contrary,  if for any
fiscal year of the  Partnership  the allocation of any loss or deduction (net of
any income or gain) to any Partner would cause or increase a negative balance in
such Partner's  Adjusted  Capital Account as of the end of such fiscal year (the
"Deficit Partner") after taking into account the provisions of subsection (h) of
this  Section 4.3,  only the amount of such loss or  deduction  that reduces the
balance to zero shall be  allocated to such  Deficit  Partner and the  remaining
loss or  deduction  shall be  allocated to the Partner  whose  Adjusted  Capital
Account has a positive balance remaining at such time (the "Positive  Partner").
After any such allocation,  any Partnership income or gain (including  Simulated
Gain)  that  would  otherwise  be  allocated  to the  Deficit  Partner  shall be
allocated  instead  to  the  Positive  Partner  up to an  amount  equal  to  the
Partnership  loss or  deduction  allocated  to the  Positive  Partner  under the
preceding  sentence;  provided,  however,  that no  allocation of income or gain
realized  shall be made under  this  sentence  if the effect of such  allocation
would be to cause the Adjusted Capital Account of the Deficit Partner to be less
than zero. If, after taking into account the allocation in the first sentence of
this Section 4.3(i), the Adjusted Capital Account balance of the Deficit Partner
remains  less than zero at the end of a fiscal  year, a pro rata portion of each
item  of  Partnership  income  or  gain  (including  Simulated  Gain)  otherwise
allocable to the Positive  Partners for such fiscal year (or if there is no such
income or gain allocable to the Positive Partners for such fiscal year, all such
income or gain (including  Simulated Gain) so allocable in the succeeding fiscal
year or years) shall be allocated to the Deficit Partner in an amount  necessary
to cause its Adjusted Capital Account balance to equal zero;  provided,  that no
allocation  under this  sentence  shall have the effect of causing the  Positive
Partner's  Adjusted  Capital  Account  to be less  than  zero.  After  any  such
allocation,  any Partnership gain (including  Simulated Gain) resulting from the
sale or other  disposition  of  Partnership  property  that would  otherwise  be
allocated  to the Deficit  Partner  for any fiscal  year under this  Section 4.3
shall be allocated  instead to the Positive  Partner until the amount of gain so
allocated  equals  the  amount of gain  (including  Simulated  Gain)  previously
allocated to such Deficit  Partner under the preceding  sentence of this Section
4.3(i); provided, however, that no allocation of gain (including Simulated Gain)
shall be made under this sentence if the effect of such  allocation  would be to
cause the Adjusted Capital Account of a Deficit Partner to be less than zero.

        Section IV.4.      Distributions.

        (a) Within five business  days after the end of each month,  the General
Partner shall cause the  Partnership to make a  distribution  (i) to the Limited
Partner  of its LP  Monthly  Cash  Distribution  for such  month and (ii) to the
General  Partner of its GP Monthly  Cash  Distribution  for such month or of its
allocable share hereunder of any Catastrophe Costs Recovery received during such
month.

        (b) Payment of all distributions  made by the Partnership to the Limited
Partner  shall  be made by wire  transfer  of  immediately  available  funds  in
accordance  with such  written  instructions  to the  General  Partner as may be
provided by the Limited Partner from time to time.

        (c)  Notwithstanding  any provision  contained in this  Agreement to the
contrary,  (i) unless  the  Limited  Partner  otherwise  consents  in writing or
defaults  in the payment of any Capital  Contributions  previously  agreed to be
made by it, the General  Partner shall not be entitled to cause the  Partnership
to retain any of the Limited  Partner's  share of  Partnership  revenues for the
purpose of paying (directly or indirectly) any Acquisition Costs, Capital Costs,
Hedge Costs,  or  Organization  Costs,  or (ii) the  Partnership may retain such
insurance  proceeds and other amounts as the General  Partner  shall  reasonably
determine are  necessary to pay  Partnership  liabilities  and expenses upon the
occurrence of an accident (e.g., a blowout),  catastrophe or similar event (and,
in connection therewith,  to restore,  preserve or protect Partnership property)
or to comply  with all  applicable  environmental  laws,  ordinances,  rules and
regulations.

        (d) Nothing  contained  in this  Section  4.4 shall  relieve the General
Partner  from its  obligation  to bear 100% of  Catastrophe  Costs  pursuant  to
Section 4.1(a).

        (e) All  distributions  in  liquidation  of a Partner's  interest in the
Partnership shall be made in accordance with Section 10.3.

                              Partnership Property

        Section V.1.       Title to Partnership Property.

        (a) All  property  owned by the  Partnership,  whether real or personal,
tangible or  intangible,  shall be deemed to be owned by the  Partnership  as an
entity, and no Partner, individually, shall have any ownership of such property.
The Partnership shall hold all of its assets in the name of the Partnership. The
General  Partner shall  promptly take all such action as it shall deem necessary
or  appropriate,  or as may be  required by law,  to perfect  and  preserve  the
ownership  interest of the  Partnership in all Leases,  and (if requested by the
Limited  Partner) upon recordation of title to a Lease shall promptly supply the
Limited Partner with a copy of such recorded title.

                                       26

        (b) Prior to  drilling  a  Partnership  well on any Lease,  the  General
Partner shall cause (or  determine  that an operator has caused) to be done such
title  examination  and title curative work as the General Partner (or operator)
shall  determine  to be  necessary  or  appropriate  with respect to such Lease;
provided,  however,  that no well shall be drilled until title to the drill site
shall have been  examined  and approved by the  examining  attorney or until any
unsatisfied title requirements shall have been waived by the General Partner (or
operator).

        Section  V.2.   Execution  and  Delivery  of  the  Purchase   Agreement;
Acquisition of the Assets.  Immediately after the execution and delivery of this
Agreement  by the parties  hereto,  the General  Partner is  authorized  to, and
shall,  execute the Purchase  Agreement on behalf of the Partnership,  provided,
the Purchase  Agreement is substantially in the form of the version submitted to
the  Partners  as the final  draft in all  material  respects.  In the event the
Purchase Agreement is executed and delivered by the General Partner on behalf of
the  Partnership in accordance  with the  immediately  preceding  sentence,  the
General Partner shall cause the Partnership to consummate the acquisition of the
Assets pursuant to the terms and conditions of the Purchase Agreement,  provided
that the  conditions  set  forth in  Section  3.2(d)  to the  Limited  Partner's
obligation to make the Capital  Contribution  referenced in Section  3.2(a) have
been satisfied.

        Section  V.3.  Additional  Acquisitions.  If,  during  the  term of this
Agreement,  the General Partner or an Affiliate thereof acquires (or proposes to
acquire) an additional  interest or interests in the Assets acquired pursuant to
the terms hereof (in this Section  called the "Subject  Leases"),  the terms and
provisions  of this  Section  5.3  shall be  operative.  Specifically,  upon the
acquisition (or proposed  acquisition) under the circumstances  described above,
the General  Partner  shall notify the Limited  Partner,  which notice shall (a)
specify the interest the General  Partner or its  Affiliates  have  acquired (or
propose to acquire) in the Subject  Leases,  (b) specify the purchase  price (or
proposed purchase price),  (c) describe the development and/or Enhanced Recovery
Operations,  if any, the General Partner reasonably  anticipates will be engaged
in on the Subject  Leases and the  estimated  costs  associated  therewith,  (d)
include a summary of the pertinent  geological and geophysical  data relating to
the Subject Leases or proposed  development/Enhanced  Recovery  Operations,  (e)
include financial  projections relating to the Subject Leases and any internally
or externally prepared related engineering or reserve reports,  (f) describe the
nature  and  extent of  planned  title  examination  and  property  related  due
diligence (including,  without limitation,  environmental due diligence) and (g)
such other  information as the General Partner deems material.  Thereafter,  the
General  Partner shall  promptly  furnish to the Limited  Partner any additional
information  concerning the Subject Leases or the proposed  development/Enhanced
Recovery  Operations as the Limited Partner may reasonably  request  (including,
without limitation,  the reports of consultants and outside engineers).  Subject
to the Limited Partner agreeing to make additional Capital  Contributions to the
Partnership  with  respect to the Subject  Leases  pursuant to Section  3.3, the
Partnership shall acquire the interest of the General Partner and its Affiliates
in such  Subject  Leases (or, if  applicable,  which the General  Partner or its
Affiliates  propose  to  acquire  therein).  Prior  to  the  acquisition  by the
Partnership of the Subject Leases,  the General Partner shall notify the Limited
Partner of any material change in the nature and extent of the title examination


                                       27
<PAGE>
and property  related due diligence plan and the reason therefor and of any fact
discovered in due diligence that materially  adversely  affects the economics or
risks  associated with the Subject Leases;  provided that no such notice need be
given to the  Limited  Partner if the  Limited  Partner  has elected not to make
additional Capital  Contributions with respect thereto.  The Limited Partner may
withdraw its election to make additional  Capital  Contributions with respect to
the  proposed  acquisition  and  related  activity,  at any  time  prior  to the
Partnership  committing  to acquire  the Subject  Leases,  by so  notifying  the
General  Partner in writing if (i) there is  discovered  during due  diligence a
fact or facts not presented to the Limited Partner in the initial  evaluation of
the proposed  acquisition  that  materially  adversely  affects the economics or
risks  associated  with the  Subject  Leases to be  acquired  and such  material
adverse effect cannot be remedied to the reasonable  satisfaction of the Limited
Partner  prior to the  acquisition  by the  Partnership  or (ii) more than three
months have passed since the Limited  Partner  notified  the General  Partner of
such Limited Partner's  election to make Capital  Contributions  with respect to
such  acquisition  and related  activity.  The  interest in each  Subject  Lease
assigned by the General  Partner and each Affiliate  thereof to the  Partnership
pursuant to this Section 5.3 shall be assigned, conveyed and transferred without
warranty of title, either express or implied,  except as to all persons claiming
or to claim the same or any part  thereof  by,  through  and  under the  General
Partner or such Affiliate but not otherwise and with a further warranty that the
General Partner or such Affiliate has not placed any lien,  encumbrance,  burden
or other  restriction on such Lease or, if the General Partner or such Affiliate
has previously placed a lien,  encumbrance,  burden or other restriction on such
Lease,  that  such  lien,  encumbrance,  burden  or other  restriction  is being
concurrently  released or has been released.  In connection with any acquisition
of Leases by the  Partnership  pursuant to this Section 5.3, the General Partner
or an Affiliate  thereof shall not retain from or otherwise  burden the interest
in any Lease  assigned  to the  Partnership  with any  overriding  royalty,  net
profits interest, carried interest, reversionary interest, production payment or
other burden in favor of itself,  its  officers,  directors and employees or any
other person, except in connection with an acquisition by the General Partner or
such  Affiliate  pursuant  to a  transaction  where  an  unrelated  third  party
transferring the Lease retains such an interest or burden with respect to all of
the Lease  acquired by the General  Partner or  Affiliate.  With respect to each
Lease acquired by the Partnership pursuant to this Section 5.3, such acquisition
shall include all rights to all horizons  under such Lease which were  available
for purchase and considered  appropriate  for  acquisition  by the  Partnership.
Under no  circumstances  shall the General  Partner or any  Affiliate  of either
thereof acquire rights to any separate  horizon within or under a Lease in which
the Partnership has an interest;  provided, that the General Partner may acquire
interests  in  zones,  strata or  horizons  occurring  below  the  stratigraphic
equivalent  of 9,460 feet as depicted in the  Compensated  Neutron  electric log
dated August 3, 1998,  of the Abraxas  Petroleum  Corporation  Echo Springs Well
#4-22-19-93,  located in the SE-NW-SE of Section 22, T19N, R93W,  Carbon County,
Wyoming,  also being the same as the top of the  Ericson  Formation  of the Mesa
Verde Group.

        Section V.4.       Lease Sales.

        (a) Except as  provided  in this  Section  5.4,  in  Section  6.2(d) and
elsewhere herein, the General Partner may sell,  farm-out,  abandon or otherwise
dispose of any  Partnership  Lease,  on such terms as the General  Partner deems
reasonable and in the best interests of the Partnership and the Limited Partner.

                                       28

        (b) Except as expressly  permitted in Section 10.3,  neither the General
Partner  or any of its  Affiliates  nor any of their  employees  shall  acquire,
directly or indirectly, any Lease (or any interest therein) from the Partnership
unless the Limited Partner has previously approved in writing such acquisition.

        Section V.5.       Sales of Production.

        (a) The General Partner shall have the right to cause the Partnership to
sell any oil or gas produced by or for the account of the Partnership, including
but not  limited to crude oil,  condensate,  natural gas liquids and natural gas
(including casinghead gas) which may be produced from or allocated to the Assets
or any  additional  Leases  acquired  pursuant  to the  terms  hereof,  to  such
purchaser  and on  such  terms  and  conditions  as the  General  Partner  shall
determine to be in the best interest of the Partnership; provided, however, that
all such sales shall be upon terms and  conditions  which are the best terms and
conditions  available as determined in good faith by the General  Partner taking
into account all relevant  circumstances,  including  but not limited to, price,
quality of production, access to markets, minimum purchase guarantees,  identity
of  purchaser,  and length of  commitment  and,  in any event,  on terms no less
favorable to the Partnership  than the General Partner or any Affiliate  thereof
has recently  obtained or is  obtaining  for arm's  length  sales,  exchanges or
dispositions of the General Partner's or such Affiliate's  production of similar
quantity  and  quality  in the same  geographic  area  where  the  Partnership's
production is located; provided, further, that the General Partner's obligations
under this Section shall be subject to the terms of Section 5.7 and  subsections
(b) and (c) below.

        (b) In marketing the  Partnership's  gas reserves,  the General  Partner
covenants and agrees that,  to the fullest  extent  possible,  it will cause the
Partnership  to  market  a  percentage  of  the  monthly  produced  gas  volumes
attributable to the Assets equal to the volumes of gas then subject to a Hedging
Transaction  under a market with a price  structure  tied to the same  commodity
index used in the hedge  formula  (i.e.,  CIG Inside  FERC's  first of the month
index).  Further,  in  connection  with the marketing of the  Partnership's  gas
reserves  under a processing  arrangement  for natural gas liquids which permits
the gas  producer  to elect  whether  to retain or reject  ethane  volumes  on a
monthly basis, the General Partner will elect to reject ethane.

        (c) Notwithstanding  anything to the contrary contained herein,  neither
the General  Partner nor any of its  Affiliates  nor any person who is a related
person within the meaning of Section 29(d)(7) of the Internal Revenue Code shall
purchase any oil or gas produced by or for the account of the Partnership.

        Section V.6. Operations on Partnership Leases. The General Partner or an
Affiliate,  shall  act  as  operator  in  connection  with  operations  on  each
Partnership  Lease unless (a) another person (other than the General  Partner or
an  Affiliate)  is currently  serving as operator  under an agreement to which a
Lease is subject or (b) any third party or third parties (not  Affiliates of the
General Partner) jointly owning such Lease and with a controlling  interest will
not otherwise  agree. As to those  Partnership  Leases with respect to which the
General Partner is not the operator, the General Partner shall take such actions


                                       29
<PAGE>

and exercise such rights and remedies  which are  reasonably  available to it to
cause the actual operator to properly develop, maintain and operate such Leases.
In the  event the  Partnership  and any third  party  jointly  own any Lease and
operations thereon are conducted pursuant to an operating agreement,  (i) if the
third party is designated as operator thereunder,  the Partnership shall pay the
costs and expenses  charged to it thereunder and (ii) if the General  Partner or
any of its  Affiliates is designated  as operator,  the General  Partner or such
Affiliate  shall receive for its account from the third party such third party's
share of all compensation and reimbursement provided to the operator thereunder;
provided, however, that the charges to the Partnership by the General Partner or
any of its Affiliates  (regardless of whether there is an operating agreement or
regardless  of whether or not a third party is also a party  thereto)  shall not
exceed  those set forth in or permitted  by this  Agreement  or the  "Accounting
Procedure"  (as herein  called)  attached  hereto as Exhibit 5.6  (although  the
operating agreement,  if any, may otherwise provide),  and in no event shall the
terms of any such  operating  agreement  vary or effect  this  Agreement  or the
Accounting  Procedure  or the  duties and  obligations  of the  General  Partner
hereunder.  The General Partner, or any Affiliate,  shall not substitute another
party as operator or assign its  obligations  as  operator  with  respect to any
Partnership Lease where it acts as operator, unless the Limited Partner requests
in the event the General  Partner is removed as such  pursuant to Section 9.4 or
the Limited  Partner  dissolves the  Partnership  pursuant to any of subsections
(c), (e), (f), (g) or (i) of Section 10.1 (and the General Partner agrees to use
its  reasonable  best  efforts to cause the  person  designated  by the  Limited
Partner to be the successor operator).

        Section V.7. Hedge Arrangement. The General Partner covenants and agrees
that,  at the  request of the  Limited  Partner  and  subject  to the  condition
described  below, the General Partner will cause the Partnership on the Delivery
Date,  to hedge up to 85% of the  Partnership's  proved  producing  gas reserves
attributable  to the Assets on such terms and conditions as are  satisfactory to
the Limited  Partner.  The General  Partner  covenants  and agrees that,  at the
request of the Limited Partner and subject to the condition  described below, it
will execute on behalf of the Partnership such additional  Hedging  Transactions
of the Partnership's  proved producing  reserves  attributable to the Assets and
any additional  Leases  acquired  pursuant to the terms hereof on such terms and
conditions as are reasonably  satisfactory to the Limited  Partner.  Any Hedging
Transaction contemplated hereunder shall be a "hedging transaction" as described
in Treasury  Regulation  ss.1.1221-2 to reduce the risk of price changes for oil
and gas produced by the  Partnership  in volumes  equal to the notional  amounts
provided in the documents  evidencing such Hedging  Transaction.  At the time of
the execution  and delivery by the  Partnership  of the  documents  evidencing a
Hedging Transaction, the General Partner shall take such additional steps as may
be necessary to identify the Hedging Transaction in the books and records of the
Partnership as a "hedging  transaction" in the manner and at the time prescribed
by Treasury Regulation ss.1.1221-2(e).

in good faith),  provided that in no event shall the General  Partner  mortgage,
pledge, assign in trust or otherwise encumber the Partnership's right to receive
Capital Contributions from the Limited Partner;

        (c) To guarantee in the name or on behalf of the Partnership the payment

        Section VI.3.      Duties and Services of General Partner.

        (a) The General  Partner  shall comply in all respects with the terms of
this  Agreement  and  shall use its  reasonable  best  efforts  (i) to cause its
Affiliates to comply with the terms of this Agreement and (ii) in the conduct of

the business and operations of the  Partnership to cause the  Partnership (A) to
comply with the terms and provisions of all agreements to which the  Partnership
is a party or to which  its  properties  are  subject,  (B) to  comply  with all

environmental  laws,  ordinances,  rules and  regulations),  (C) to  obtain  and
maintain all licenses, permits, franchises and other governmental authorizations
necessary  with  respect to the  ownership  of  Partnership  properties  and the

General  Partner  shall  not be  required  to devote  full  time to  Partnership
business;  and (iii) subject to the other express  provisions of this Agreement,
the Limited Partner  acknowledges  that the General Partner currently engages in

Partnership  shall  indemnify  and save  harmless  the General  Partner from any
costs,  expenses,  losses or damages  (including  attorneys'  fees and expenses,
court costs, judgments and amounts paid in settlement) incurred by reason of its
being  General  Partner,  provided  it has acted in good  faith on behalf of the
Partnership and the Limited Partner and in a manner reasonably believed by it to
be within the scope of the authority  granted to it by this Agreement and in the
best  interests of the  Partnership,  and provided  further that (i) the General
Partner was not guilty of a material breach of this Agreement, gross negligence,
willful or wanton  misconduct  or breach of fiduciary  duty with respect to such
acts or omissions,  and (ii) the  satisfaction  of any  indemnification  and any
saving harmless shall be from and limited to Partnership  assets (which shall be
converted to cash to the extent necessary in a manner appropriate to protect the
interests of all Partners) and not from any Capital  Contributions to be made by
the  Limited  Partner  hereunder,  and the  Limited  Partner  shall not have any
personal liability on account thereof.

        Section VI.5. Limitations on Indemnification.  The rights of the General
Partner under Section 6.4 with respect to  indemnification  from the Partnership
shall be subject to the provisions of Article 11 of the Act. Any indemnification

unless the General  Partner  was wholly  successful  on the merits,  only upon a
determination  by a  court  upon  the  request  of  the  General  Partner  or by
independent  legal counsel  selected by the General Partner and  satisfactory to
the Limited  Partner in a written  opinion that  indemnification  of the General
Partner  is  permitted  (a)  under  the  circumstances  because  it has  met the
applicable  standard  of conduct  set forth in Section  6.4 and (b)  pursuant to
Article 11 of the Act.

        Section VI.6.      Costs, Expenses and Reimbursement.

        (a)  Subject to the other  express  provisions  of this  Agreement,  all
direct,  third-party out of pocket costs and expenses reasonably incurred in the

obtaining audits of the Partnership's  books and records (including the fees and
expenses of the  Partnership's  independent  public  accountants),  the fees and
expenses  attributable to the preparation of the  Partnership's  tax returns and
reports, the fees and expenses of the independent  petroleum engineer referenced
in  Section  8.2(f),  outside  legal  costs,  general  taxes and  other  direct,
third-party out of pocket costs and expenses of the Partnership.

        (b) Commencing on the Purchase  Agreement  Closing Date, the Partnership
shall pay, and the General  Partner shall be entitled to receive,  a monthly fee
(the  "Management  Fee") in an amount  equal to 1% of Net  Operating  Income (as
defined below) for such month;  provided,  that the General Partner shall not be
paid the  Management  Fee for any  month  (or  portion  thereof)  in  which  the
Partnership's  right to receive revenues has been assigned to a trustee pursuant
to Section 6.11, if the General Partner withdraws from the Partnership or if the
General Partner has been removed as provided herein;  provided further, that the
General  Partner shall not be paid the  Management Fee for any month (or portion
thereof)  during  which the business  and affairs of the  Partnership  are being
wound up for  liquidation  purposes  pursuant  to Section  10.3,  if the General


                                       34
<PAGE>
Partner is not acting as liquidator hereunder.  With respect to the month during
which the Purchase Agreement Closing Date occurs and the last month during which
the  Management  Fee is  payable  hereunder  if the  obligation  to pay such fee
terminates prior to the last day of such month, the monthly Management Fee shall
be  prorated  based on the number of days during such month in which the General
Partner is entitled to receive the Management Fee divided by the total number of
days in such month.  As used in this  subsection  (b),  the term "Net  Operating
Income" shall mean,  with respect to a given month,  (i) the gross  proceeds for
such  month  received  by  the  Partnership  and  attributable  to  any  Hedging
Transaction  plus  (ii) the  gross  proceeds  for  such  month  received  by the
Partnership  from the sale of  hydrocarbons  (other  than in  connection  with a
Hedging  Transaction)  minus (iii) any  Hedging  Costs for such month minus (iv)
Lease Operating and Production Costs for such month.

        (c) Except as provided in Section  5.6,  this Section 6.6 and in Section
6.7,  the  General  Partner  and  its  Affiliates  shall  not be paid  any  fee,
compensation or reimbursement or be entitled to or charge the Partnership for or
on  account  of  their  services,  services  of  their  officers,  employees  or
consultants,  fees  or  compensation  of  those  geologists,  geophysicists  and
engineers  who are  employed  by them or  otherwise  retained  by  them,  office
expense, overhead or any other general or administrative costs or expense.

        Section VI.7.  Organization  Costs.  The  Partnership  from time to time
shall pay  directly,  or shall  reimburse  the  General  Partner and the Limited
Partner for any payment by them of, the following fees and expenses  incurred in
connection  with the  initial  organization  of the  Partnership  ("Organization
Costs"):  (a) all reasonable fees and expenses  incurred by them (including fees
for outside legal services) in connection with the preparation and filing of all
certificates,  opinions and documents required pursuant to Sections 1.2 and 1.6;

diligence  review  of the  Assets  and  (iii) the  closing  of the  transactions
contemplated  under the  Purchase  Agreement;  and (d) all  reasonable  fees and
expenses of legal counsel to the Limited  Partner in connection with the Limited
Partner's  consideration of any waiver of its rights under this Agreement or any
proposed amendment or supplement to this Agreement.

        Section VI.8. Insurance. The General Partner shall cause the Partnership
to obtain  (and  maintain  during the entire  term of the  Partnership),  or the
General  Partner  shall  carry for the  benefit  of the  Partnership,  insurance
coverage in such amounts,  with provisions for such  deductible  amounts and for
such  purposes as the General  Partner and the Limited  Partner have agreed upon
below and  thereafter  shall  agree  upon in  writing on or about July 1 of each
year. Where appropriate,  the General Partner may include the Partnership or the
Limited Partner as additional  insureds on any policies otherwise carried by the
General Partner and the costs thereof shall be allocated to the Partnership on a
basis  mutually  agreed upon in writing by the  General  Partner and the Limited
Partner from time to time.  The Partners  hereby agree that the General  Partner
shall initially carry for the benefit of the Partnership  insurance  coverage in
the amounts,  with provisions for such deductible  amounts and for the purposes,
specified in Exhibit 6.8. Thereafter,  the Partners shall review and endeavor in
good faith to agree upon the Partnership's insurance coverage as provided above.

In the event the General  Partner incurs any  Catastrophe  Costs pursuant to the
terms hereof, the Partners agree that the General Partner shall be subrogated to
any claims or actions the Partnership  may have  attributable to or arising from
the events or  circumstances  with respect to which the  Catastrophe  Costs were
incurred;  provided,  that the maximum amount that the General  Partner shall be
entitled to recover  pursuant to the rights granted under this sentence (and the
extent of such  subrogation)  shall be the  amount of the  Catastrophe  Costs so
incurred (which amount shall be herein called the "Catastrophe Costs Recovery").

        Section VI.9.      Tax Elections.

        (a) The General Partner shall make the following  elections on behalf of
the Partnership:

                  (i)  To  elect,  in  accordance  with  Section  263(c)  of the
        Internal  Revenue Code and applicable  regulations and comparable  state

                  (iii) To elect the accrual method of accounting;

                  (iv)  If  requested  by the  Limited  Partner,  to  elect,  in
        accordance  with Sections 734, 743 and 754 of the Internal  Revenue Code
        and applicable  regulations  and  comparable  state law  provisions,  to
        adjust basis in the event any  Partnership  interest is  transferred  in
        accordance   with  this  Agreement  or  any   Partnership   property  is
        distributed to any Partner;

                  (v) To elect to treat all organizational and start-up costs of
        the Partnership as deferred  expenses  amortizable  over 60 months under
        Sections 195 and 709 of the Internal Revenue Code; and

                  (vi) To elect with  respect to such other  federal,  state and
        local tax matters as the General  Partner and the Limited  Partner shall
        agree upon from time to time.

        (b) No  Partner  shall  elect or cause  the  Partnership  to elect to be
treated as an association taxable as a corporation.

        (c) The General  Partner agrees to use its best efforts to cause any tax
partnership  which  governs  any of the Assets or  additional  Leases  hereafter
acquired  pursuant to the terms hereof to make an election  under Section 754 of
the  Internal  Revenue  Code  if  such  election  would  be  beneficial  to  the
Partnership.

        Section VI.10. Tax Returns. The General Partner shall prepare and timely
file all  federal,  state and local  income and other tax returns and reports as


                                       36
<PAGE>

may be required as a result of the business of the  Partnership,  which  returns
shall  be  signed  by  the  independent  certified  public  accountants  of  the
Partnership.  Not less than 30 days prior to the date (as extended) on which the
Partnership  intends to file its federal  income tax return or any state  income
tax return,  the return  proposed to be filed by the  General  Partner  shall be
furnished to the Limited Partner for review and comments. In addition,  not more
than 10 days after the date on which the Partnership  actually files its federal
income tax return or any state income tax return,  a copy of the return so filed
by the General  Partner shall be furnished to the Limited  Partner.  The General
Partner  shall be designated  the tax matters  partner under Section 6231 of the
Internal  Revenue Code and shall promptly  notify the Limited Partner if any tax
return  or  report of the  Partnership  is  audited  or if any  adjustments  are
proposed by any  governmental  body.  In  addition,  the General  Partner  shall
promptly furnish to the Limited Partner all notices concerning administrative or
judicial  proceedings  relating to federal  income tax matters as required under
the Internal  Revenue Code.  During the pendency of any such  administrative  or
judicial  proceeding,  the General  Partner shall furnish to the Limited Partner
periodic reports, not less often than monthly, concerning the status of any such
proceeding.  Without  the consent of the Limited  Partner,  the General  Partner
shall not extend the statute of limitations,  file a request for  administrative
adjustment,  file suit  concerning any tax refund or deficiency  relating to any
Partnership  administrative  adjustment or enter into any  settlement  agreement
relating to any Partnership item of income,  gain, loss, deduction or credit for
any fiscal year of the Partnership.

        Section VI.11.  Appointment of Trustee to Receive Payments.  The Limited
Partner may cause the  Partnership  at the  Partnership's  expense to assign the
Partnership's  right to  receive  revenues  to a  trustee  named by the  Limited
Partner (a) if the General Partner has committed  fraud,  willful or intentional
misconduct or gross negligence in the performance of its duties  hereunder,  (b)
if the General  Partner  has  defaulted  in the  performance  of its  obligation
hereunder  to make a  distribution  of cash or  property  due and  owing  to the
Limited Partner,  (c) if the General Partner is in default in the performance or
observance  of any  other  material  agreement,  covenant,  term,  condition  or
obligation  hereunder,  which  default must have  continued for not less than 30
days after the General  Partner has knowledge  thereof or after  written  notice
thereof given by the Limited  Partner has been received by the General  Partner,
(d) if a representation or warranty made by the General Partner herein or by the
General  Partner or any of its officers in any writing  furnished in  connection
with or pursuant  to this  Agreement  shall be false in material  respect on the
date as of which made, or (e) upon the occurrence of any of the events described
in either  Section  4.02(a)(4) or in Section  4.02(a)(5) of the Act (except that
with  respect to Section  4.02(a)(5)  the  operative  number of days shall be 60
instead of those set forth in such Section). Such trustee shall receive and hold
Partnership revenues for the benefit of all the Partners, but shall not have the
rights  of  the  General  Partner  hereunder.   The  trustee's  sole  right  and
responsibility  shall be to  receive  Partnership  funds  and  disburse  them in
accordance with the other  provisions of this Agreement.  In the event a trustee
is  appointed  pursuant  to this  Section  6.11 and the  default is cured or the
action  or event  under or with  respect  to the  bankruptcy  law is  completely
dismissed or eliminated,  the General  Partner and the Limited Partner shall, at
the request of either the  General  Partner or the  Limited  Partner,  cause the
trustee to be  discharged  at the  Partnership's  expense;  provided that in the
judgment of the Limited  Partner,  its interest under this Agreement will not be
adversely affected by any such discharge.

those  required in Section 1.07 of the Act) kept at the principal  United States

not have the  authority or power in its capacity as a Limited  Partner to act as
agent for or on behalf of the  Partnership or any other  Partner,  to do any act
which would be binding on the Partnership or any other Partner,  or to incur any
expenditures  on behalf  of or with  respect  to the  Partnership.  The  General
Partner  shall not hold out or  represent  to any third  party that the  Limited
Partner  has any such right or power or that the  Limited  Partner  is  anything
other than a "limited partner" in the Partnership.

        Section VII.3.  Liability of Limited Partner.  The Limited Partner shall
not be liable for the debts, liabilities,  contracts or other obligations of the
Partnership except to the extent of any unpaid Capital  Contributions  agreed to
be made by the  Limited  Partner  as set forth in Section  3.2  (which  shall be
subject to reduction as provided for in Section  3.4),  any  additional  Capital
Contributions  hereafter  agreed to be made by the Limited Partner in accordance

undistributed  revenues)  of the  Partnership;  and in all  events,  the Limited
Partner  shall  be  liable  and  obligated  to  make  payments  of  its  Capital
Contributions  only as and when such  payments  are due in  accordance  with the
terms of this  Agreement,  and the Limited Partner shall not be required to make
any loans to the Partnership.  The Partnership shall indemnify and hold harmless
the Limited Partner in the event it (a) becomes liable for any debt,  liability,
contract or other  obligation of the Partnership  except to the extent expressly
provided in the preceding sentence or (b) is directly or indirectly  required to
make any payments with respect thereto.

        Section VII.4. Access of Limited Partner to Data. During the term of the
Partnership,  the  Partnership  may  acquire  or  have  access  to  geophysical,
geological and other similar data and  information.  The Limited Partner and its

termination of the Partnership, shall have the right to inspect, review and copy
any such data or information (or studies,  maps,  evaluations or reports derived
therefrom)  which  relates to the Assets or other Leases  which the  Partnership
owns or has  owned or which  has been  paid for with  Partnership  funds  and to
consult with the  Partnership's  independent  certified  public  accountants and


                                       38
<PAGE>

with respect to Partnership matters. Upon liquidation of the Partnership, copies
of all such documents  shall be  distributed  to the General  Partner and to the
Limited Partner if so requested by it.

        Section  VII.5.  Withdrawal  and  Return of  Capital  Contribution.  The
Limited  Partner  shall not be entitled  to (a)  withdraw  from the  Partnership
except upon the assignment by the Limited  Partner of all of its interest in the
Partnership and the substitution of such Limited Partner's assignee as a Limited
Partner of the  Partnership in accordance with Section 9.1, or (b) the return of
its Capital  Contributions except to the extent, if any, that distributions made
pursuant to the express terms of this Agreement may be considered as such by law
or by unanimous  agreement of the Partners,  or upon dissolution and liquidation
of the Partnership,  and then only to the extent expressly  provided for in this
Agreement and as permitted by law.

                                  ARTICLE VIII

                    Books, Records, Reports and Bank Accounts

        Section VIII.1.    Capital Accounts, Books and Records.

        (a) Except as may otherwise be required by this  Agreement,  the General
Partner  shall keep books of account  for the  Partnership  in  accordance  with
generally accepted accounting principles consistently applied in accordance with
the terms of this  Agreement.  Such books shall be  maintained  at the principal
United States office of the  Partnership  and shall be maintained by the General
Partner for review by the Limited Partner during the term of the Partnership and
for a period of five years  thereafter.  The calendar  year shall be selected as
the  accounting  year of the  Partnership  and the  books  of  account  shall be
maintained on an accrual basis.

        (b) An individual capital account shall be maintained by the Partnership
for each Partner as provided below:

                  (i) The  capital  account  of each  Partner  shall,  except as
        otherwise  provided  herein,  be (A)  credited  by such  Partner's  cash
        Capital  Contributions  when made, (B) credited by the fair market value
        of any property  contributed to the  Partnership by such Partner (net of
        liabilities secured by such contributed property that the Partnership is
        considered  to  assume  or take  subject  to  under  Section  752 of the
        Internal  Revenue  Code),  (C)  credited  with the amount of any item of
        taxable  income  or gain and the  amount  of any item of  income or gain
        exempt from tax  allocated  to such  Partner  (taking  into  account any
        reallocation  pursuant to Sections 3.3 and 3.6),  (D) credited  with the
        Partner's  share of Simulated Gain as provided in paragraph (ii) of this
        Section  8.1(b),  (E) debited by the amount of any item of tax deduction
        or loss allocated to such Partner (taking into account any  reallocation
        pursuant to Sections 3.3 and 3.6), (F) debited with the Partner's  share
        of Simulated Loss and Simulated  Depletion as provided in paragraph (ii)
        of this Section 8.1(b), (G) debited by such Partner's allocable share of


                                       39
<PAGE>
        expenditures   of  the  Partnership  not  deductible  in  computing  the
        Partnership's  taxable  income and not  properly  chargeable  as capital
        expenditures,   including  any  non-deductible   book  amortizations  of
        capitalized  costs,  and (H)  debited  by the amount of cash or the fair
        market  value  of any  property  distributed  to  such  Partner  (net of
        liabilities  secured by such  distributed  property that such Partner is
        considered  to  assume  or take  subject  to  under  Section  752 of the
        Internal Revenue Code).  Immediately prior to any distribution of assets
        by  the  Partnership  that  is  not  pursuant  to a  liquidation  of the
        Partnership or all or any portion of a Partner's  interest therein,  the
        Partners'  capital  accounts  shall be adjusted by (X) assuming that the
        distributed  assets  were  sold by the  Partnership  for  cash at  their
        respective  fair  market  values as of the date of  distribution  by the
        Partnership and (Y) crediting or debiting each Partner's capital account
        with its respective share of the hypothetical gains or losses, including
        Simulated Gains and Simulated Losses,  resulting from such assumed sales
        in the same  manner as each such  capital  account  would be  debited or
        credited   for  gains  or  losses  on  actual   sales  of  such  assets.
        Notwithstanding  the  foregoing  sentence,  the  Partnership  shall  not
        distribute  any  property in kind to any  Partner  except as provided in
        Section 10.3.

                  (ii)  The   allocation   of  basis   prescribed   by   Section
        613A(c)(7)(D)  of the Internal  Revenue Code and provided for in Section
        4.3(b) and each Partner's separately computed depletion deductions shall
        not reduce such Partner's  capital account,  but such Partner's  capital
        account  shall be  decreased  by an amount  equal to the  product of the
        depletion   deductions   that  would   otherwise  be  allocable  to  the
        Partnership  in the  absence of Section  613A(c)(7)(D)  of the  Internal
        Revenue  Code  (computed   without  regard  to  any  limitations   which
        theoretically   could  apply  to  any  Partner)   times  such  Partner's
        percentage share of the adjusted basis of the property (determined under
        Section  4.3(b)) with respect to which such depletion is claimed (herein
        called "Simulated Depletion"). The Partnership's basis in any Depletable
        Property  as  adjusted  from  time to time for the  Simulated  Depletion
        allocable  to  all  Partners  (and  where  the  context  requires,  each
        Partner's  allocable  share thereof,  which share shall be determined in
        the same manner as the allocation of basis prescribed in Section 4.3(b))
        is herein called  "Simulated  Basis". No Partner's capital account shall
        be decreased, however, by Simulated Depletion deductions attributable to
        any  Depletable  Property  to the extent  such  deductions  exceed  such
        Partner's allocable share of the Partnership's remaining Simulated Basis
        in  such  property.   The  Partnership   shall  compute  simulated  gain
        ("Simulated Gain") or simulated loss ("Simulated Loss")  attributable to
        the sale or other  disposition  of a  Depletable  Property  based on the
        difference   between  the  amount  realized  from  such  sale  or  other
        disposition  and the Simulated  Basis of such  property,  as theretofore
        adjusted.  Any  Simulated  Gain shall be  allocated  to the Partners and
        shall increase their  respective  capital accounts in the same manner as
        the amount  realized  from such sale or other  disposition  in excess of
        Simulated  Basis shall have been allocated  pursuant to Section  4.3(b).
        Any  Simulated  Loss shall be allocated to the Partners and shall reduce
        their  respective  capital accounts in the same percentages as the costs
        of the  property  sold  were  allocated  up to an  amount  equal to each
        Partner's share of the Partnership's Simulated Basis in such property at
        the time of such sale.

                  (iii)  Any  adjustments  of  basis  of  Partnership   property
        provided for under Sections 734 and 743 of the Internal Revenue Code and
        comparable  provisions of state law  (resulting  from an election  under
        Section 754 of the Internal  Revenue Code or  comparable  provisions  of
        state law) and any  election  by an  individual  Partner  under  Section

                                       40
<PAGE>
        59(e)(4) of the Internal  Revenue Code to amortize such Partner's  share
        of  intangible  drilling  and  development  costs  shall not  affect the
        capital  accounts  of  the  Partners  (unless   otherwise   required  by
        applicable  Treasury  Regulations),  and the Partners'  capital accounts
        shall be debited or credited  pursuant to the terms of this  Section 8.1
        as if no such election had been made.

                  (iv)  Capital   accounts  shall  be  adjusted,   in  a  manner
        consistent with this Section 8.1, to reflect any adjustments in items of
        Partnership  income,  gain,  loss or deduction  that result from amended
        returns  filed by the  Partnership  or pursuant to an  agreement  by the
        Partnership with the Internal Revenue Service or a final court decision.

                  (v) In the  case  of  property  carried  on the  books  of the
        Partnership  at an amount which  differs from its  adjusted  basis,  the
        Partners'  capital  accounts  shall be debited or credited  for items of
        depreciation, cost recovery, Simulated Depletion,  amortization and gain
        or loss  (including  Simulated  Gain or Simulated  Loss) with respect to
        such  property  computed  in the  same  manner  as such  items  would be
        computed if the adjusted tax basis of such  property  were equal to such
        book value,  in lieu of the capital account  adjustments  provided above
        for  such  items,  all  in  accordance  with  Treasury   Regulation  ss.
        1.704-1(b)(2)(iv)(g).

                  (vi) It is the  intention  of the  Partners  that the  capital
        accounts of each Partner be kept in the manner  required  under Treasury
        Regulation   ss.   1.704-1(b)(2)(iv).   To  the  extent  any  additional
        adjustment to the capital accounts is required by such  regulation,  the
        General  Partner  is hereby  authorized  to make such  adjustment  after
        notice to the Limited Partner.

         Section  VIII.2.  Reports.  The General  Partner  shall  deliver to the
Limited  Partner the  following  financial  statements  and reports at the times
indicated below:

report is given,  while the Partnership  has any direct  drilling  operations in

an  explanation of the  abandonment  of any well which has been abandoned  after

        (c)  Monthly,  within 30 days after the end of each month for which such
report is given,  a schedule  prepared on a cash basis  setting  forth (i) total

Hedging  Transaction  through the end of such month for the  current  settlement

Partnership and annually within 90 days after the end of each fiscal year of the
Partnership  (commencing  with the fiscal year ending  December 31, 1998, in the
instance of the annual  report),  (i) financial  statements as of the end of and
for such period,  including a balance sheet and statements of income,  Partners'
equity,  status of Payout and cash flows,  prepared in accordance with generally
accepted  accounting  principles  and,  with  respect  to the  annual  financial
statements,  accompanied by a report of the Partnership's  independent certified

financial  statements  fairly  present  the  Partnership's  financial  position,
results  of  operations  and cash flow in  accordance  with  generally  accepted
accounting  principles  consistently  applied,  and (B) in the normal  course of
making the  examination  and  reporting on the  financial  statements  described
above, nothing came to their attention which caused them to believe that (1) the
revenues and costs and expenses  allocated  to the Partners  hereunder  were not
allocated  in  accordance  with  the  specific  allocation  provisions  of  this
Agreement and (2) the General  Partner failed to comply in any material  respect

failed,  a  statement  specifying  the nature and  period of  existence  of such
failure,  (ii) a schedule  reflecting  for such  period  the total  costs of the

and its  Affiliates,  which  summaries  shall be  accompanied by a report of the
Partnership's independent certified public accountants stating that in preparing
such summaries nothing came to their attention which caused them to believe that
any  transaction  between the General  Partner or an  Affiliate  thereof and the
Partnership did not comply with Section 6.2(n) or Section 6.6, or if they did so
conclude,  a  statement  specifying  such  noncompliance,  and  (iv) a  schedule

<PAGE>

the Partnership  shall be Ernst & Young LLP or such other nationally  recognized
firm of independent  certified public  accountants as shall be designated by the
General Partner and approved by the Limited Partner.

        (f)  Annually  within 90 days after the end of each  fiscal  year of the
Partnership,  beginning with the fiscal year ending  December 31, 1998, a report
containing  (i) an  estimation  of the  oil  and  gas  reserves,  classified  by

petroleum engineers, and shall be based on such assumptions as to costs, product
prices and similar  factors as (x)  prescribed  by Rule 4-10 of  Regulation  S-X
promulgated  by the  Securities  and  Exchange  Commission  and (y) the  Limited

                                   ARTICLE IX

                   Assignments of Interests and Substitutions

        Section IX.1.      Assignments by Limited Partner.

        (a) The  interest of the  Limited  Partner in the  Partnership  shall be
assignable in whole or in part, subject to the following: (i) no such assignment
shall be made if such assignment would result in the violation of any applicable
federal or state securities laws, (ii) the Partnership  shall not be required to
recognize any such assignment  until the instrument  conveying such interest has
been  delivered  to the  General  Partner  for  recordation  on the books of the
Partnership and (iii) the Limited Partner shall have first complied with Section
9.6.

        (b)  Unless  an  assignee  becomes  a  substituted  Limited  Partner  in
accordance  with the  provisions  set forth below,  such  assignee  shall not be
entitled to any of the rights granted to the Limited  Partner  hereunder,  other
than the right to receive allocations of income, gain, loss,  deduction,  credit
and similar items and  distributions  to which the assignor  would  otherwise be
entitled, to the extent such items are assigned.

                                       44
<PAGE>

        (c) An assignee of the interest of the Limited  Partner,  or any portion
thereof,  shall  become a  substituted  Limited  Partner  entitled to all of the
rights  of the  Limited  Partner  if,  and only if (i) the  assignor  gives  the
assignee  such  right,  (ii) the  General  Partner,  in its  sole  and  absolute
discretion,  consents to such  substitution and (iii) the assignee  executes and
delivers such instruments,  in form and substance reasonably satisfactory to the
General  Partner,  as the General  Partner may deem  necessary  or  desirable to
effect such  substitution  and to confirm the  agreement  of the  assignee to be
bound  by  all  of  the  terms  and  provisions  of  this  Agreement.  Upon  the
satisfaction of such requirements, the General Partner shall concurrently (or as
of  such  later  date  as  shall  be  provided  for  in any  applicable  written
instruments  furnished  to the  General  Partner)  admit any such  assignee as a
substituted  Limited  Partner of the  Partnership and reflect such admission and
the date thereof in the records of the Partnership.

        (d) The  Partnership  and the General Partner shall be entitled to treat
the record owner of any  Partnership  interest as the absolute  owner thereof in
all  respects and shall incur no liability  for  distributions  of cash or other
property  made  in good  faith  to  such  owner  until  such  time as a  written
assignment of such  interest that complies with the terms of this  Agreement has
been received by the General Partner.

        Section IX.2. Assignment by General Partner. The interest of the General
Partner in the Partnership shall not be assigned,  mortgaged, pledged, subjected
to a security interest or otherwise encumbered, in whole or in part, without the
prior  written  consent  of  the  Limited  Partner  in  its  sole  and  absolute
discretion.

        Section IX.3. Merger or Consolidation. Notwithstanding the provisions of
Sections  9.1 or 9.2,  the merger or  consolidation  by a Partner  with  another
corporation  shall  not  be  considered  an  assignment  of an  interest  in the
Partnership, and upon the merger or consolidation of such Partner, the resulting
corporation shall continue as a Partner.

        Section IX.4.      Removal of General Partner.

        (a) Subject to the provisions hereof, the Limited Partner may remove the
General Partner with cause and select a new General Partner to operate and carry
on the business and affairs of the Partnership.  As used in this Section 9.4 and
in Section 9.5,  "with cause" shall mean the occurrence of any of the following:
(i) the  commission  by the  General  Partner of fraud,  willful or  intentional
misconduct or gross negligence in the performance of its duties hereunder;  (ii)
a default by the General  Partner in the  performance of its obligation to cause
the  Partnership to make a distribution of cash or property due and owing to the
Limited  Partner;  (iii) a default by the General  Partner in the performance or
observation  of any other  material  agreement,  covenant,  term,  condition  or
obligation  hereunder,  which  default must have  continued for not less than 30
days after the General  Partner has knowledge  thereof or after  written  notice
thereof given by the Limited  Partner has been received by the General  Partner;
(iv) a  representation  or warranty made by the General Partner herein or by the
General  Partner or any of its officers in any writing  furnished in  connection
with or pursuant to this Agreement shall be false in any material respect on the
date as of which made;  (v) the  occurrence  of any of the events  described  in


                                       45
<PAGE>
Section  4.02(a)(4) or Section 4.02(a)(5) of the Act with respect to the General
Partner or Parent (except that with respect to Section 4.02(a)(5), the operative
number of days shall be 60 instead of the  numbers  set forth in such  Section);
(vi) a  material  adverse  change in  Parent's  financial  condition  taken on a
consolidated  basis that may have a material  adverse effect on the Partnership,
as reasonably determined by the Limited Partner in its sole discretion;  (vii) a
material adverse change in the Partnership's operations or properties (including
the value thereof) as reasonably  determined by the Limited  Partner in its sole
discretion,  taking into account whether such material  adverse change is due to
factors beyond the reasonable control of the General Partner; (viii) the General
Partner is no longer a  wholly-owned  subsidiary  of  Parent;  (ix) a default by
Parent in the  performance or observation  of any agreement,  covenant,  term or
condition or obligation under the Guaranty; and (x) a representation or warranty
made by Parent or by Parent or any of its  officers in any writing  furnished in
connection  with or pursuant to this Agreement or the Guaranty shall be false in
any material respect on the date as of which made.

        (b)  For  purposes  of  illustration,  but not by way of  limitation,  a
material adverse change in Parent's financial  condition taken on a consolidated
basis for  purposes  of  clause  (vi) of  subsection  (a) above may be deemed to
include (i) the failure of the Parent to pay any  portion,  when such portion is
due,  of any of its  indebtedness  or a  breach  or  default  by  Parent  of any
agreement  or  instrument  by which  such  indebtedness  is  issued,  evidenced,
governed or secured,  and any such failure,  breach or default  continues beyond
any applicable  period of grace provided  therefor;  (ii) a breach or default by
Parent of any other material  agreement or other instrument to which Parent is a
party or by which it or any of its properties are bound; (iii) the entry against
Parent of a final,  non-appealable  judgment for the payment of money;  and (iv)
the  issuance of a writ of  attachment  or any similar  process by any  tribunal
against all or any substantial part of Parent's assets.

        (c)  For  purposes  of  illustration,  but not by way of  limitation,  a
material adverse change in the Partnership's operations or properties (including
the value  thereof) for purposes of clause (vii) of subsection  (a) above may be
deemed to include (i) if cumulative  production  attributable to such properties
for any 12-month  period is less than 85% of the forecasted  production for such
period as set forth in that certain reserve report prepared by Cawley  Gillespie
& Associates,  Inc. dated October 1, 1998 (in this subsection, the "CGA Report")
(and determined on a mmbtu basis),  or (ii) if cumulative lease operating costs,
on an mcf equivalent basis, for any 12-month period are greater than 115% of the
forecasted lease operating costs for such period as set forth in the CGA Report,
taking into account (in the instance of both clause (i) or clause (ii),  whether
such decrease in production or increase in lease operating costs, as applicable,
is due to factors beyond the reasonable control of the General Partner.

        (d) Any successor  General Partner will be named in, and its appointment
as such will be  effective  as of a date  specified  in, a notice to the General
Partner  from the  Limited  Partner  exercising  its right to remove the General
Partner and select the  successor  General  Partner.  The removal of the General
Partner shall be effective only if and when the following  conditions  have been
satisfied:  (i) a successor  General  Partner shall have been selected and shall
have agreed to accept the  responsibilities of a General Partner;  and (ii) this
Agreement and the Certificate of Limited  Partnership of the  Partnership  shall
have been duly amended to name the new General  Partner.  To the extent required
by the laws of any  jurisdiction  to which the  Partnership or this Agreement is


                                       46
<PAGE>
subject,  the  Partners  hereby  unanimously  consent to the  admission  of such
successor  General Partner and hereby appoint such successor  General Partner as
the agent and attorney in fact for each Partner  (including  without  limitation
the retiring General Partner) for the purpose of signing, swearing to and filing
an amendment to the  certificate of limited  partnership of the  Partnership and
all other necessary or appropriate documents in connection with the substitution
of such successor General Partner.

        (e) The  provisions  of this Section 9.4 shall not be the sole remedy of
the Limited Partner in the event the General Partner is removed with cause,  and
in such event the  Partnership  and/or the Limited  Partner shall have all other
rights and remedies as shall be available to them pursuant to this Agreement, at
law or in  equity to  redress  any  wrong or  damage  arising  from the event or
circumstances giving rise to the General Partner's removal with cause.

        Section IX.5.  Rights of General Partner Upon Removal.  In the event the
General Partner is removed in accordance with Section 9.4, the incoming  General
Partner shall have the right to purchase from the removed  General Partner a one
percent  general  partner  interest in the  Partnership  at a price equal to the
appraised value thereof. Such appraised value shall be determined by a qualified
independent  appraiser who is mutually  agreed upon by both the removed  General
Partner and the incoming  General  Partner within 30 days after the selection of
the incoming  General  Partner.  If the removed General Partner and the incoming
General Partner cannot mutually agree upon a single independent appraiser within
such period,  they shall each select their own  independent  appraiser and those
two  appraisers  shall select a third  independent  appraiser.  The cost of such
appraisal shall be borne by the removed General  Partner.  The incoming  General
Partner's  option to  acquire  such  interests  must be  exercised  by notice in
writing to the removed General Partner not more than 20 days after the selection
of the incoming  General  Partner and the purchase price for such interest shall
be paid in cash not more than 30 days after receipt by the parties of the report
of the appraiser  setting forth the appraised  value.  In the event the incoming
General  Partner  does not elect to  purchase  the one percent  general  partner
interest of the removed  General  Partner  pursuant  to the  provisions  of this
Section 9.5, such interest shall be converted to a limited  partner  interest in
the Partnership. Further, in any event any remaining general partner interest of
the removed General Partner in the Partnership  (i.e., the additional  interests
to be received  after the  Cumulative  Payout No. 1,  Cumulative  Payout No.2 or
Cumulative Payout No. 3) shall be converted to a limited partner interest in the
Partnership  and the removed General Partner shall continue as a limited partner
in  accordance  with  Section  6.02 of the Act,  but  without any right to vote,
consent,  approve or  otherwise  make any  determination  under this  Agreement;
provided,  that after such conversion any amendment to this Agreement that would
change  (a) the  status of the  removed  General  Partner  as a limited  partner
hereof,  (b) the removed General  Partner's  participation in the income,  gain,
loss,  credits or  distributions  of the  Partnership,  (c) the removed  General
Partner's  obligation  to  contribute  capital  to the  Partnership  or (d) this
proviso, shall require the written consent of the removed General Partner.

        Section 9.6        Right of First Offer.

        (a) Each time the  Limited  Partner  proposes  to make any sale or other
disposition of all or any portion of its interest in the Partnership (other than


                                       47
<PAGE>

a sale or other  disposition  to a person  controlling,  controlled  by or under
common control with the Limited  Partner and whether or not the Limited  Partner
has received an offer for such  interest),  the Limited  Partner shall so inform
the General  Partner by notice in writing (in this Section  9.6,  the  "Transfer
Notice")  describing  the interest (or portion  thereof)  that is the subject of
such proposed  disposition (in this Section 9.6, the "Offered Interest") and the
other  terms  and  conditions  of  such  proposed  disposition,   including  any
consideration  proposed to be received  for the Offered  Interest  (and,  if the
proposed  Disposition  is to be wholly or partly  for  consideration  other than
money, the Transfer Notice shall state the amount of the monetary consideration,
if any, and shall  describe all  non-monetary  consideration  and state the fair
market value  thereof).  If the General  Partner  disagrees with the fair market
value of the  non-monetary  consideration  as described in the Transfer  Notice,
then such fair market  value shall be  determined  by an  independent  appraiser
agreed upon by both Partners  (provided,  that if Partners  cannot agree upon an
independent  appraiser  within 15 days of the Transfer  Notice,  they shall each
elect their own  independent  appraiser  within 10 days after the  expiration of
such 15-day  period and those two  independent  appraisers  shall select a third
independent  appraiser  within  10 days  after  the  expiration  of such  10-day
period).  By giving the Transfer Notice,  the Limited Partner shall be deemed to
have  granted to the General  Partner an option to  purchase  all of the Offered
Interest for the price and upon the terms set forth in the  Transfer  Notice (as
modified by any such appraiser(s)). Such option may be exercised with respect to
all (but not less than all) the Offered  Interest by the General  Partner giving
notice in writing of its  intention to exercise the option which is delivered to
the Limited Partner within thirty days after the later of the General  Partner's
receipt  of the  Transfer  Notice  or the  selection  of the  three  independent
appraisers  (if  applicable).  If the General  Partner does not deliver any such
notice to the Limited Partner within such thirty-day period, all of such Offered
Interest  may be  disposed  of by the  Limited  Partner for the price and on the
terms and conditions  set forth in the Transfer  Notice (as modified by any such
appraiser(s)),  at  any  time  within  120  days  after  the  expiration  of the
thirty-day  option period,  but any such disposition shall be subject to Section
9.1.

        (b) If the General  Partner timely  exercises any option to purchase the
Offered Interest pursuant to Section 9.6(a),  the purchase price of such Offered
Interest shall be the monetary  consideration  set forth in the Transfer  Notice
plus the fair market value of any  non-monetary  consideration  set forth in the
Transfer Notice (as modified by any such  appraiser(s))  and shall be payable by
the General  Partner to the Limited Partner in cash. The closing of the purchase
and sale of an Offered  Interest  shall take place on the 15th day following the
date of  delivery  to the Limited  Partner of the  General  Partner's  notice of
election to purchase the Offered Interest (or if such day is a Saturday, Sunday,
or legal holiday in the State of  Connecticut,  the first day thereafter that is
not a Saturday,  Sunday,  or legal  holiday) at 10:00 a.m.,  local time,  in the
office of the Limited Partner set forth on the Limited Partner's  signature page
of this Agreement, or on such other date and at such other time and place as may
be agreed to by both Partners.  At the closing,  the Limited  Partner shall take
all action necessary to convey the Offered Interest to the General Partner, free
of all liens and encumbrances.

has been received by the Parent,  (iii) if a representation  or warranty made by

<PAGE>

any material  respect on the date as of which made, or (iv) upon the  occurrence

such Section).

        (j) The  occurrence  of any other  event  which under the Act causes the

        Section X.2.       Withdrawal by General Partner and Reconstitution.

        (a) Except as specifically permitted in Section 9.2, the General Partner
covenants  and  agrees not to (i)  withdraw  voluntarily  from the  Partnership,
either directly,  by dissolution,  by transfer of its Partnership interest or by
any other  voluntary act (including  without  limitation any event of withdrawal
from the  Partnership by the General  Partner as provided in Section  4.02(a) of
the Act), or (ii) allow seizure, attachment,  garnishment,  foreclosure or other
taking of its  Partnership  interest.  Notwithstanding  anything to the contrary
contained in this Section 10.2, in Section 10.1 or elsewhere in this  Agreement,
the General  Partner shall not merge or consolidate  with, or assign or transfer
its interest in the Partnership  to, any third party  (including an Affiliate or
any other party related to the General  Partner) if such merger,  consolidation,
assignment or transfer will result in the termination of the Partnership for tax
purposes.  If the General Partner breaches any provision of this Section 10.2 or
Section 9.2, if an event described in Section 10.1(e) occurs,  or if an election
is made by the Limited Partner to dissolve the  Partnership  pursuant to Section
10.1(f) or Section 10.1(i),  all interests and amounts which the General Partner
would  otherwise  receive  under  Section  10.3 (as  General  Partner but not as
Limited Partner, unless such limited partnership interest is held by the General
Partner as a result of Section 9.4 of this Agreement if the General  Partner has
been removed for cause) shall be reduced by the following applicable percentages
of  such  interest  and  amount:  90%  if the  withdrawal  occurs  prior  to the
expiration  of the  Phase I  Period;  75% if the  withdrawal  occurs  after  the
expiration  of the Phase I Period  but prior to the  expiration  of the Phase II
Period; 50% if the withdrawal occurs after the expiration of the Phase II Period
but prior to the  expiration of the Phase III Period;  and 10% if the withdrawal
occurs during the Phase IV Period.  The  distribution  to the Limited Partner of
assets  which  would  otherwise  be  distributable  to the  General  Partner  in
accordance  with this Section 10.2 shall  constitute  liquidated  damages to the
Limited  Partner for a  violation  by the General  Partner of the  covenant  and
agreement  contained  in the first  sentence of this Section  10.2,  the parties
having agreed that the amount of actual damages would be difficult or impossible
to calculate.

        (b) Notwithstanding the foregoing Section 10.2(a) or any other provision
of this Agreement,  (i) the Partnership  may be  reconstituted  and its business
continued  without being wound up as provided for in Section 8.03 of the Act and
(ii) the provisions of Section 6.02 (including without limitation subsection (b)
thereof) of the Act shall be applicable to the Partnership except that the right
to recover  damages from the  withdrawing  General  Partner  pursuant to Section
6.02(a) of the Act shall be governed by Section 10.2(a) of this Agreement.

        Section  X.3.  Liquidation  and  Termination.  Upon  dissolution  of the
Partnership (unless it is reconstituted and its business continued without being


                                       50
<PAGE>
wound up as provided for in Section  10.2(b)),  the General Partner shall act as
liquidator or may appoint in writing one or more liquidators who shall have full
authority to wind up the affairs of the Partnership and make final  distribution
as provided herein;  provided,  however,  that if one of the events specified in
Section  10.1(c),(e),  (f), (g) or (i) has occurred as a result of an act by the
General  Partner,  the liquidator  shall be a person  selected in writing by the
Limited  Partner.  The  liquidator  shall  continue to operate  the  Partnership
properties with all of the power and authority of the General Partner.
The steps to be accomplished by the liquidator are as follows:

        (a) As  promptly  as possible  after  dissolution  and again after final
liquidation,  the liquidator  shall cause a proper  accounting to be made by the
Partnership's  independent accountants of the Partnership's assets,  liabilities
and operations through the last day of the month in which the dissolution occurs
or the final liquidation is completed, as appropriate.

        (b) The  liquidator  shall pay all of the debts and  liabilities  of the
Partnership  (including all expenses  incurred in liquidation) or otherwise make
adequate provision therefor (including without limitation the establishment of a
cash escrow fund for contingent  liabilities in such amount and for such term as
the liquidator may reasonably determine).  After making payment or provision for
all debts and liabilities of the  Partnership,  the Partners'  capital  accounts
shall then be adjusted by (i) assuming the sale of all  remaining  assets of the
Partnership for cash at their respective fair market values (as determined by an
appraiser  mutually  determined by the Partners  within 30 days after receipt by
the Limited Partner of notice that the liquidator has paid or made provision for
all debts and  liabilities of the  Partnership) as of the date of termination of
the Partnership, (ii) assuming the distribution of such cash at such time in the
percentages  required  under Sections 4.2 and 4.4,  taking into account  whether
Cumulative  Payout No. 1, Cumulative Payout No. 2 or Cumulative Payout No. 3 has
occurred or would occur as a result of such distribution,  and (iii) debiting or
crediting  each  Partner's  capital  account  with its  respective  share of the
hypothetical  gains or  losses  resulting  from such  assumed  sales in the same
manner as each such  capital  account  would be debited or credited for gains or
losses on actual  sales of such  assets.  In the event that the Limited  Partner
fails to notify the General Partner of its selection of an appraiser pursuant to
the preceding  sentence within the time period  specified  therein,  the General
Partner shall be entitled to select such appraiser. The liquidator shall then by
payment  of cash or  property  (valued  as of the  date  of  termination  of the
Partnership  at its fair market  value by the  appraiser  selected in the manner
provided  above)  distribute to the Partners such amounts as are required to pay
the  positive  balances  of their  respective  capital  accounts.  To the extent
possible  and  provided  that the  ownership  of such  property  would not be in
violation of any rule or regulation then applicable to the Limited Partner, such
a  distribution  shall be in kind  unless  otherwise  agreed  to by the  General
Partner  and the  Limited  Partner.  In  making  distributions  of  property  in
satisfaction of such capital account balances,  the liquidator shall distribute,
to  the  extent  possible,  undivided  interests  in  each  Lease  in  the  same
percentages as the Partners  share revenues from such Lease.  Each Partner shall
have the  right to  designate  another  person to  receive  any  property  which
otherwise would be distributed in kind to that Partner  pursuant to this Section
10.3 and Section 10.2 if that Section is applicable.  Any  distributions  to the
Partners in liquidation of the Partnership shall be made by the later of the end


                                       51
<PAGE>
of the taxable year in which the liquidation  occurs,  or 90 days after the date
of  such  liquidation.   For  purposes  of  the  preceding  sentence,  the  term
"liquidation"  shall have the same  meaning as set forth in Treasury  Regulation
ss. 1.704-1(b)(2)(ii)(g) as in effect at such time.

        (c) Any  Leases  distributed  to the  Partners  shall be  subject to the
operating  agreements  then in effect  with  respect to such  Leases;  provided,
however,  that if any of such  Leases is subject to an  operating  agreement  to
which an unaffiliated  third person is not a party, such Leases shall be subject
to a standard form operating  agreement as shall be agreed upon by the Partners.
Upon  written  request  made by any  Partner,  the  liquidator  shall  sell  the
Partnership  Leases and other  properties  and assets  that  otherwise  would be
distributable  to such  Partner  under this  Section 10.3 at the best cash price
available  therefor  and  distribute  such cash (after  deducting  all  expenses
reasonably relating to such sale) to such Partner.  Such sale shall be on behalf
of such Partner and shall be treated as the sale by such Partner of its interest
in such  properties,  and any  gain or loss  attributable  to such  sale and any
proceeds therefrom shall be for the account of such Partner.

        (d) The provisions of subsections (b) and (c) of this Section 10.3 shall
be subject to the effect of Section 10.2 if that Section is applicable.

        (e) Except as expressly  provided  herein,  the liquidator  shall comply
with  any  applicable  requirements  of the Act and all  other  applicable  laws
pertaining  to the  winding up of the affairs of the  Partnership  and the final
distribution of its assets.

        The  distribution  of cash and/or  property  to the Limited  Partners in
accordance with the provisions of this Section 10.3 shall  constitute a complete
return to the  Limited  Partner  of its  Capital  Contributions  and a  complete
distribution  to the Limited Partner of its interests in the Partnership and all
Partnership  property. No Partner with a negative balance in its capital account
shall be liable to the  Partnership  or any other Partner for the amount of such
negative balance upon dissolution and liquidation.

        Section X.4.  Cancellation  of  Certificate.  Upon the completion of the
distribution of Partnership  assets as provided herein, the Partnership shall be
terminated,  and the liquidator  (or the Partners if necessary)  shall cause the
cancellation  of the  certificate of limited  partnership of the Partnership and
shall take such other actions as may be necessary to terminate the Partnership.

result in any breach or constitute a default  under any  applicable  law,  rule,
regulation,  judgment,  license,  permit  or  order or any  loan,  note or other

        (f) When delivered to the Limited Partner, this Agreement will have been

documents with respect to the  qualification or reformation and operation of the
Partnership  as a limited  partnership  under the laws of any state in which the
Partnership  owns  properties  or  conducts  business  so  as  to  require  such
qualification.

        (i) Neither the General  Partner nor any of its  Affiliates has employed
or retained any broker, agent or finder in connection with this Agreement or the
transactions  contemplated  herein,  or paid or agreed to pay any brokerage fee,
finder's  fee,  commission  or similar  payment to any person on account of this
Agreement or the transactions provided for herein; and the General Partner shall

                                       53
<PAGE>
broker,  agent  or  finder  employed  or  retained  by the  General  Partner  in
connection with the Partnership or this Agreement.

        (j) As of the date  hereof  none of the  financial  statements  or other
written  documents or  information  delivered  herewith or  heretofore  by or on
behalf of the General  Partner to the  Limited  Partner in  connection  with the

hereunder contains any untrue statement of a material fact or omits to state any
material  fact  (other than facts which the  Limited  Partner  recognizes  to be
industry risks normally  associated with the oil and gas business)  necessary to
keep the statements contained herein or therein from being misleading.  There is
no fact  peculiar to the General  Partner or the Assets  (other than facts which
the Limited Partner recognizes to be industry risks normally associated with the
oil and gas business) which  materially  adversely  affects or in the future may
(so far as the General Partner can now foresee) materially  adversely affect (i)
the business,  property or assets, or financial condition of the General Partner
or (ii) the Assets, and which has not been set forth in this Agreement or in the
other documents, certificates and statements furnished to the Limited Partner by
or on behalf of the General Partners prior to the date hereof in connection with
the transactions contemplated hereby.

        (k) To the best knowledge of the General  Partner,  the General  Partner
and its Affiliates and persons acting on their behalf have not taken any action,
or  failed  to take  any  action,  which  has  caused  the  organization  of the
Partnership  and the issuance of the interests in the Partnership to come within
the registration  requirements of the Securities Act of 1933, as amended, or any
applicable state blue sky laws.

        (l)  There  is no  pending  or,  to the  best of the  General  Partner's
knowledge,  threatened  judicial,  administrative  or arbitral  action,  suit or
proceeding  against or  investigation  of the General Partner which is not fully
insured against (except standard  deductible amounts) and which might materially
and  adversely  affect the  financial  condition  of the General  Partner or its
ability to perform its obligations under this Agreement.

        (m) During the preceding  12-month  period,  the General Partner and its
Affiliates and persons acting on their behalf have not sold (except to a limited
number of persons who have represented themselves to be accredited investors, as
defined in Rule 501  promulgated by the Securities and Exchange  Commission) any
interest in the Partnership or similar  interests;  with respect to any sales of
interests  similar to the  Partnership by the General Partner and its Affiliates
and persons acting on their behalf  subsequent to the Delivery Date, the General
Partner shall do nothing which would require the registration of these interests
under the  Securities  Act of 1933,  and the rules and  regulations  promulgated
thereunder, as well as applicable state securities laws.

Limited  Partner  represents,  warrants and covenants to the General  Partner as
follows:

        (a) It is duly  organized,  validly  existing and in good standing under

Certificate  or  Articles  of  Incorporation  or Bylaws,  as amended to the date

under  any  applicable  law,  rule or  regulation  or any  loan,  note or  other
agreement  or  instrument  to  which  it is a party or by which it or any of its
properties are bound.

be a waiver of such Partner's  right to demand strict  compliance in the future.
No consent or waiver,  express or implied, to or of any breach or default in the
performance of any obligation  hereunder shall constitute a consent or waiver to
or of any other  breach or default in the  performance  of the same or any other
obligation hereunder.

        Section  XII.6.  Applicable  Law.  This  Agreement  and the  rights  and
obligations  of the parties  hereunder  shall be  governed  by and  interpreted,

applicable  law or by  obligations  pursuant to any listing  agreement  with any
national  securities  exchange shall only be made after reasonable notice to the
other party.

        Section XII.12.  Arbitration.  Any dispute arising out of or relating to
this  Agreement,  any schedule,  certificate or other document  delivered by any
party  in  connection  with  this  Agreement  or  incident  to the  transactions
contemplated  hereby  or  thereby  or the  breach,  inaccuracy,  termination  or
validity  hereof or thereof  or  otherwise  arising  out of or  relating  to the
transactions  contemplated hereby and thereby, or any other agreement among them
or between any of them,  whether  entered into prior to, on or subsequent to the
date of this  Agreement or those arising under any federal,  state or local law,
regulation  or  ordinance,   shall  be  determined  by  binding  arbitration  in
accordance with the then current  Commercial  Arbitration  Rules of the American
Arbitration Association. If the amount in controversy in the arbitration exceeds
Two Hundred Fifty Thousand Dollars ($250,000), exclusive of interest, attorneys'
fees and costs, or if a single neutral  arbitrator  cannot be agreed upon within
thirty (30)  calendar  days after a dispute has arisen which is to be decided by
arbitration,  the arbitration shall be conducted by a panel of three (3) neutral
arbitrators.  Otherwise,  the arbitration shall be conducted by a single neutral
arbitrator.  The parties shall endeavor to select neutral  arbitrators by mutual
agreement.  If such agreement cannot be reached within thirty (30) calendar days
after a dispute  has arisen  which is to be decided by  arbitration,  each party
shall select its own neutral arbitrator within 15 days of the expiration of such
30-day period and the two neutral  arbitrators  so selected shall select a third
neutral arbitrator within 10 days of the expiration of such 15-day period. The 3
persons thus selected shall be the  arbitrators for such  arbitration.  If three
(3)  arbitrators  are selected,  the  arbitrators  shall elect a chairperson  to
preside at all meetings and  hearings.  If a dispute is to be resolved by a sole
arbitrator  in  accordance  with the terms  hereof,  or if the  dispute is to be
resolved by a panel of three (3) arbitrators as provided hereinabove,  then such
sole arbitrator or the chairperson of such panel, as the case may be, shall be a
member of a state bar engaged in the  practice of law in the United  States or a
retired  member of a state or the federal  judiciary in the United  States.  The
award of the  arbitrator(s)  shall require a majority of the  arbitrators in the
case of a panel of arbitrators, shall be in writing and reasoned, shall be based
on the evidence admitted and the substantive law of the State of Texas and shall
contain an award for each issue and counterclaim. The award shall be made within
thirty (30) days  following the close of the final hearing and the filing of any
post  hearing  briefs  authorized  by  the  arbitrator(s).   The  award  of  the
arbitrator(s)  shall be final and binding on the parties  hereto and the subject
matter.  Judgment upon the award rendered by the arbitrator(s) may be entered by
any court  having  jurisdiction.  The place of  arbitration  shall be in Dallas,
Texas.  Each party  shall be  entitled  to inspect and obtain a copy of relevant
documents  in  the  possession  or  control  of the  other  party  and  to  take
depositions  of  the  other  parties'  employees,  agents,  representatives  and
witnesses  (including  expert  witnesses).   All  such  discovery  shall  be  in


                                       57
<PAGE>
accordance  with  procedures  approved by the  arbitrator(s).  Unless  otherwise
provided  in the award,  each party shall bear its own costs of  discovery.  All
discovery  shall be expedited,  consistent with the nature and complexity of the
claim or dispute and  consistent  with fairness and justice.  The  arbitrator(s)
shall have the power to compel any party to comply  with  discovery  requests of
the other parties and to issue binding orders relating to any discovery  dispute
which shall be enforceable in the same manner as awards.  The arbitrator(s) also
shall  have the  power to  impose  sanctions  for  abuse or  frustration  of the
arbitration  process,  including without limitation,  the refusal to comply with
orders of the arbitrator(s) relating to discovery and compliance with subpoenas.
Each of the parties hereto hereby irrevocably submits to the jurisdiction of the
courts of the State of Texas for entry of any arbitration  decision or to obtain
any  preliminary  relief  which may be  necessary  and  hereby  consents  to the
enforcement by such courts of any award rendered in such arbitration.

        Section XII.13. Voting Rights.  Without affecting rights with respect to
allocations  and  distributions  and the rights,  duties and  obligations of the
General Partner  hereunder,  at no time will a majority of the voting  interests
under  ordinary  circumstances  with respect to the  Partnership  be held by the
General Partner.

        Section XII.14. Counterparts.  This Agreement may be executed in several
counterparts,  each of which shall be deemed an original  and all of which shall
constitute but one and the same instrument.

unproven  leasehold  interests  and  Section  29 tax  credits,  plus a 1% equity
interest in the  partnership,  which could increase to 35% and higher based upon
achievement  of certain  agreed upon rates of return.  Abraxas will  continue to
operate the properties. The effective date of the transaction is October 1, 1998
and the transaction is expected to close before November 30, 1998.

The properties consist of approximately 11,300 gross acres (8,700 net acres) and
57 gross wells (44 net wells).  Independent petroleum consultants,  DeGolyer and
MacNaughton,  estimate that as of December 31, 1997,  the  properties  had total
proved reserves of 76.6 BCFE.

Robert L. G. Watson, Chief Executive Officer of Abraxas, stated "The sale of the
Wyoming  properties is consistent  with our strategy of selling fully  developed
properties so that we can maintain  financial  flexibility and redeploy proceeds
to  new  acquisition,   exploration  and  development   activities  with  upside
potential."
