                 SUBJECT TO COMPLETION, DATED DECEMBER 23, 1996

PROSPECTUS
                          ABRAXAS PETROLEUM CORPORATION
                       CANADIAN ABRAXAS PETROLEUM LIMITED
             OFFER TO EXCHANGE 11.5% SENIOR NOTES DUE 2004, SERIES B
                    FOR ANY AND ALL OUTSTANDING 11.5% SENIOR
                            NOTES DUE 2004, SERIES A

           THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
               TIME, ON ________________, 199__, UNLESS EXTENDED.

        Abraxas Petroleum  Corporation,  a Nevada corporation  ("Abraxas"),  and
Canadian Abraxas Petroleum  Limited, a Canada  corporation  ("Canadian  Abraxas"
and, together with Abraxas, the "Issuers"), hereby offer (the "Exchange Offer"),
upon the terms and conditions set forth in this  Prospectus  (the  "Prospectus")
and the  accompanying  Letter of Transmittal (the "Letter of  Transmittal"),  to
exchange $1,000 principal amount of their 11.5% Senior Notes due 2004,  Series B
(the "Exchange  Notes"),  which have been registered under the Securities Act of
1933, as amended (the "Securities Act"), pursuant to a Registration Statement of
which this  Prospectus  is a part,  for each  $1,000  principal  amount of their
outstanding  11.5%  Senior Notes due 2004,  Series A (the "Series A Notes"),  of
which  $215,000,000  principal amount is outstanding.  The form and terms of the
Exchange  Notes are the same as the form and terms of the Series A Notes  (which
they  replace)  except  that  (i)  the  Exchange  Notes  will  bear a  Series  B
designation,  (ii) the  Exchange  Notes  will  have  been  registered  under the
Securities Act and, therefore,  will not bear legends restricting their transfer
and will not be subject to certain  provisions  relating  to an  increase in the
interest  rate  which  were   applicable  to  the  Series  A  Notes  in  certain
circumstances  relating to the timing of the Exchange Offer and (iii) holders of
the  Exchange  Notes will not be  entitled  to certain  rights of holders of the
Series A Notes under the  Registration  Rights  Agreement  (as defined  herein),
which  rights will  terminate  upon  consummation  of the  Exchange  Offer.  The
Exchange  Notes will  evidence  the same debt as the Series A Notes  (which they
replace)  and will be  issued  under  and be  entitled  to the  benefits  of the
Indenture  dated November 14, 1996 (the  "Indenture")  among the Issuers and IBJ
Schroder  Bank & Trust  Company  governing the Series A Notes and the Exchange B
Notes.  As used herein,  the term "Notes"  refers to both the Series A Notes and
the Exchange Notes. See "The Exchange Offer" and "Description of the Notes."

        Interest on the Exchange Notes will be payable  semi-annually in arrears
on May 1 and November 1 of each year,  commencing on May 1, 1997, at the rate of
11.5% per annum.  Interest will accrue from the date of issuance of the Series A
Notes (November 14, 1996). The Exchange Notes will be redeemable, in whole or in
part,  at the  option of the  Issuers,  on or after  November  1,  2000,  at the
redemption prices set forth herein, plus accrued and unpaid interest to the date
of  redemption.  In addition,  at any time on or prior to November 1, 1999,  the
Issuers may, at their option, redeem up to 35% of the aggregate principal amount
of the Notes originally  issued with the net cash proceeds of one or more Equity
Offerings  (as defined  herein),  at a  redemption  price equal to 111.5% of the
aggregate  principal  amount of the Exchange Notes to be redeemed,  plus accrued
and unpaid interest to the date of redemption;  provided,  however,  that, after
giving  effect  to any such  redemption,  at  least  $139.75  million  aggregate
principal amount of Notes remains outstanding.

        The Exchange Notes will be general unsecured  obligations of the Issuers
and will  rank  pari  passu  in right of  payment  to all  existing  and  future
unsubordinated  indebtedness of the Issuers. The Exchange Notes will rank senior
in right of payment to all future subordinated  indebtedness of the Issuers. The
Exchange  Notes  will,   however,   be  effectively   subordinated   to  secured
indebtedness  of the  Issuers to the extent of the value of the assets  securing
such indebtedness. See "Description of the Notes."

        The  Exchange  Notes will be  unconditionally  guaranteed,  jointly  and
severally,  by certain of the  Issuers'  future  subsidiaries  (the  "Subsidiary
Guarantors").  The  Guarantees  (as defined  herein)  will be general  unsecured
obligations  of the  Subsidiary  Guarantors and will rank pari passu in right of
payment to all  unsubordinated  indebtedness  of the  Subsidiary  Guarantors and
senior in right of payment to all  subordinated  indebtedness  of the Subsidiary
Guarantors.   The  Guarantees  will  be  effectively   subordinated  to  secured
indebtedness  of the  Subsidiary  Guarantors  to the  extent of the value of the
assets  securing  such  indebtedness.  See  "Description  of  the  Notes."  Upon
consummation  of the Offering,  the Issuers and the Subsidiary  Guarantors  will
have no secured indebtedness outstanding.

        Abraxas has entered into a credit  facility (the "New Credit  Facility")
with Bankers Trust Company  ("BTCo") and ING (U.S.)  Capital  Corporation  ("ING
Capital")  which is secured  by certain  assets of  Abraxas  and  guaranteed  by
Canadian Abraxas.  The New Credit Facility has an initial  availability of $20.0
million.  As of December 20, 1996, there were no borrowings under the New Credit
Facility outstanding.

        Upon a Change of Control (as defined  herein),  each holder of the Notes
will have the right to require  the  Issuers to  repurchase  all or a portion of
such holder's Notes at a redemption  price equal to 101% of the principal amount
thereof,  plus  accrued  and  unpaid  interest  to the  date of  repurchase.  In
addition, the Issuers will be obligated to offer to repurchase the Notes at 100%
of the principal  amount thereof plus accrued and unpaid interest to the date of
repurchase in the event of certain asset sales. See "Description of the Notes."

        The Issuers will accept for exchange any and all Series A Notes  validly
tendered  and  not  withdrawn  prior  to 5:00  p.m.,  New  York  City  time,  on
__________,  199_,  unless extended by the Issuers in their sole discretion (the
"Expiration  Date").  Tenders of the Series A Notes may be withdrawn at any time
prior to 5:00 p.m. on the  Expiration  Date.  The  Exchange  Offer is subject to
certain  customary  conditions.  The Series A Notes were sold by the  Issuers on
November  14,  1996 to the  Initial  Purchasers  (as  defined  herein)  and were
thereupon  sold by the Initial  Purchasers  in reliance upon Rule 144A under the
Securities  Act,  to a limited  number of  qualified  institutional  buyers that
agreed  to comply  with  certain  transfer  restrictions  and other  conditions.
Accordingly,  the  Series  A  Notes  may not be  offered,  resold  or  otherwise
transferred in the United States unless  registered  under the Securities Act or
unless  an  applicable  exemption  from  the  registration  requirements  of the
Securities Act is available.  The Exchange Notes are being offered  hereunder in
order to satisfy the  obligations of the Issuers under the  Registration  Rights
Agreement  entered into by the Issuers and the Initial  Purchasers in connection
with the offering of the Series A Notes. See "The Exchange Offer."

        Based on an  interpretation  by the staff of the Securities and Exchange
Commission  (the  "Commission")  set forth in no-action  letters issued to third
parties,  the Issuers  believe  that the Exchange  Notes issued  pursuant to the
Exchange  Offer may be offered for resale,  resold and otherwise  transferred by
any holder  thereof (other than any such holder that is an "affiliate" of either
of the  Issuers  within the  meaning of Rule 405 under the  Securities  Act or a
broker-dealer  who  purchased  the Series A Notes  directly from the Issuers for
resale  pursuant  to Rule 144A or another  exemption  from the  Securities  Act)
without compliance with the registration and prospectus  delivery  provisions of
the  Securities  Act,  provided  that such  Exchange  Notes are  acquired in the
ordinary course of such holder's  business and such holder has no arrangement or
understanding  with  any  person  to  participate  in the  distribution  of such
Exchange Notes. See "Purpose of the Exchange Offer" and " Resale of the Exchange
Notes." Each  broker-dealer that receives the Exchange Notes for its own account
pursuant  to  the  Exchange  Offer  (a   "Participating   Broker-Dealer")   must
acknowledge  that it will deliver a prospectus in connection  with any resale of
such Exchange Notes.  The Letter of Transmittal  states that by so acknowledging
and by delivering a prospectus, a participating Broker-Dealer will not be deemed
to admit that it is an  "underwriter"  within the meaning of the Securities Act.
This Prospectus,  as it may be amended or supplemented from time to time, may be
used by a Participating Broker-Dealer in connection with resales of the Exchange
Notes received in exchange for the Series A Notes where such Series A Notes were
acquired  by such  Participating  Broker-Dealer  as a  result  of  market-making
activities or other trading  activities.  The Issuers agreed that they will make
this  Prospectus  available  to  any  Participating  Broker-Dealer  for  use  in
connection  with any such resale  during the period  required by the  Securities
Act. See "Plan of Distribution."

        There has not  previously  been any public market for the Series A Notes
or the Exchange  Notes.  The Issuers do not intend to list the Exchange Notes on
any securities  exchange or to seek approval for quotation through any automated
quotation  system.  There  can be no  assurance  that an active  market  for the
Exchange  Notes  will  develop.  See "Risk  Factors  -- Lack of Public  Market."
Moreover, to the extent that the Series A Notes are tendered and accepted in the
Exchange  Offer,  the trading  market for untendered and tendered but unaccepted
Series A Notes could be adversely affected.

        The Exchange Notes will be available  initially only in book-entry form.
The Issuers expect that the Exchange Notes issued pursuant to the Exchange Offer
will be issued in the form of a Global  Certificate (as defined  herein),  which
will be  deposited  with,  or on behalf of, The  Depository  Trust  Company (the
"Depositary"  or "DTC") and registered in its name or in the name of Cede & Co.,
its nominee.  Beneficial  interests in the Global  Certificate  representing the
Exchange   Notes  will  be  shown  on,  and   transfers   thereof  to  qualified
institutional  buyers  will  be  affected  through,  records  maintained  by the
Depositary  and its  participants.  After the  initial  issuance  of the  Global
Certificate, the Exchange Notes in certified form will be issued in exchange for
the  Global  Certificate  only on the  terms  set  forth in the  Indenture.  See
"Book-Entry; Delivery and Form."

        Holders of the Series A Notes not  tendered and accepted in the Exchange
Offer will  continue  to hold such Series A Notes and will be entitled to all of
the  rights and  benefits  and will be  subject  to the  limitations  applicable
thereto under the Indenture  and with respect to transfer  under the  Securities
Act. The Issuers will not receive any proceeds from the Exchange Offer. Pursuant
to the  Registration  Rights  Agreement,  the Issuers  will pay all the expenses
incurred by them incident to the Exchange Offer. See "The Exchange Offer."

        SEE "RISK  FACTORS" ON P. 16 FOR A  DESCRIPTION  OF CERTAIN  RISKS TO BE
CONSIDERED BY HOLDERS WHO TENDER THEIR SERIES A NOTES IN THE EXCHANGE OFFER.

        THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND  EXCHANGE  COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS  THE
COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED  UPON THE  ACCURACY  OR
ADEQUACY OF THIS PROSPECTUS.  ANY  REPRESENTATION  TO THE CONTRARY IS A CRIMINAL
OFFENSE.

                                   THE COMPANY

        The Company is an independent  energy company  engaged  primarily in the
acquisition,  exploration,  development  and production of crude oil and natural
gas.  Since January 1, 1991,  the Company's  principal  means of growth has been
through the acquisition and subsequent development and exploitation of producing
properties and related assets.  The Company  utilizes a disciplined  acquisition
strategy,  focusing  its efforts on  producing  properties  and  related  assets
possessing  the  following  characteristics:   a  concentration  of  operations;
significant,  quantifiable  development  potential;  historically  low operating
expenses; and the potential to reduce G&A expenses per BOE. The Company seeks to
complement   its   acquisition   and   development   activities  by  selectively
participating in exploration projects with experienced industry partners.  After
giving  effect to the Recent  Acquisitions,  the  Company's  principal  areas of
operation are Texas,  western Canada and southwestern  Wyoming. The Company owns
interests in 225,290 gross acres  (126,845 net acres) and 507 gross wells (325.8
net wells),  352 of which are operated by the Company,  and varying interests in
13 natural  gas  processing  plants or  compression  facilities.  On a pro forma
basis,  at June 30, 1996,  the Company  would have had total proved  reserves of
45,647  MBOE  (64.9%  natural  gas),  of which  81.7%  would  have  been  proved
developed.  On a pro forma basis,  for the nine months ended September 30, 1996,
the Company's EBITDA would have been $28.4 million.

        The Company's  acquisition,  development,  exploitation  and exploration
activities  have  substantially  increased  the Company's  proved  reserve base,
average daily  production  and natural gas  processing  plant  throughput  while
decreasing its total  operating and G&A expenses per BOE. After  consummation of
the Recent Acquisitions,  the Company has completed 16 acquisitions of producing
properties totaling 46,009 MBOE of proved reserves at an average net acquisition
cost of $3.83 per BOE since  January  1,  1991.  From  January  1,  1991,  on an
historical  basis,  to June 30, 1996, on a pro forma basis,  the Company's total
proved  reserves would have increased from 889 MBOE to 45,647 MBOE and aggregate
PV-10 would have increased from $11.9 million to $218.3 million. From January 1,
1991, on an historical  basis, to the nine months ended September 30, 1996, on a
pro forma basis,  average net daily  production  would have increased from 0.141
MBOE per day to _14.1 MBOE per day. On a pro forma basis, the Company would have
had net natural gas  processing  capacity of 128.1 MMcf per day as of  September
30, 1996. In addition, on a pro forma basis, for the nine months ended September
30, 1996,  average net daily natural gas processing  plant throughput would have
been 87.4 MMcf per day, of which 27.3 MMcf would have been  processed  for third
parties,  and net operating revenue from processing natural gas of third parties
at the Canadian Abraxas Plants (as defined herein) would have been $1.9 million.
From the year ended  December  31, 1991,  on an  historical  basis,  to the nine
months ended  September  30, 1996, on a pro forma basis,  the  Company's  direct
operating  expenses per BOE would have decreased from $6.30 per BOE to $2.81 per
BOE and G&A  expenses per BOE would have  decreased  from $5.39 per BOE to $0.66
per BOE. As a result of the Company's  successful  acquisition  strategy and its
ability to decrease its direct operating and G&A expenses per BOE, the Company's
EBITDA  (excluding  interest  income) has increased  from $6.66 per BOE, for the
year ended December 31, 1991,  to, on a pro forma basis,  $7.24 per BOE, for the
nine months ended September 30, 1996.

        The Company was founded in 1977 by Robert  L.G.  Watson,  the  Company's
Chairman of the Board,  President and Chief Executive Officer.  Canadian Abraxas
was formed by the  Company  in 1996 to acquire  CGGS.  The  Company's  principal
offices are located at 500 North Loop 1604 East,  Suite 100, San Antonio,  Texas
78232 and its telephone number is (210) 490-4788.  Canadian  Abraxas'  principal
offices are located at 630 - 6th Avenue,  S.W., Suite 303, Calgary,  Alberta and
its telephone number is (403) 262-1949.

                                BUSINESS STRATEGY

        The  Company's   primary  business   objectives  are  to:  increase  its
recoverable reserves, production and cash flow from operations through strategic
acquisitions;  exploit and develop its producing  properties;  maintain low cost
operations;  and pursue a focused  exploration  strategy.  The Company  seeks to
achieve its business objectives through the use of the following strategies:

         Disciplined  Acquisition  Strategy.  The Company utilizes a disciplined
acquisition  strategy,  focusing its acquisition efforts on producing properties
and related assets possessing the following characteristics:  a concentration of
operations;  significant,  quantifiable development potential;  historically low
operating  expenses;  and the  potential  to reduce G&A  expenses  per BOE.  The
success of the Company's  acquisition  strategy is  illustrated by the following
table:

interest in Portilla,  East White Point and Stedman Island  previously  owned by
the Pension Fund (as defined herein).
7) Does not include results of operations of the Partnership (as defined herein)
from March 21, 1996 to June 30, 1996 or proceeds  from the Acco Sale (as defined
herein).

        In connection with the acquisition of the Sinton Properties, the Company
also acquired  interests in two natural gas processing  plants, one of which was
subsequently sold in the Acco Sale. See "-- Recent  Acquisitions -- Portilla and
Happy." Since being  acquired by the Company,  the average net daily natural gas
processing  throughput  of these plants has  increased by an average of 7.3% per
year,  revenue  has  increased  by an  average  of 24.5% per year and  operating
expenses as a percentage  of revenue  have  decreased by an average of 13.7% per
year.

         Exploitation   Of  Existing   Properties.   The  Company   allocates  a
significant amount of its non-acquisition  capital budget to the exploitation of
its  producing  properties.  As  of  June  30,  1996,  on  a  pro  forma  basis,
approximately  18.3% (8,373 MBOE) of the Company's  total proved  reserves would
have  been  classified  as  proved  undeveloped.  Management  believes  that the
proximity of these undeveloped reserves to existing production makes development
of these  properties  less risky and more  cost-effective  than  other  drilling
opportunities available to the Company. The Company has identified 272 potential
exploitation  opportunities on the Company's existing properties including those
acquired in the Recent  Acquisitions.  The Company  drilled 29 wells  during the
first nine months of 1996 (including seven in western Canada) at a total cost of
$7.9 million with a success rate of 93%. In addition, the Company has drilled or
plans  to  drill  a  total  of 37  wells  and  has  performed  42  workovers  or
recompletions  during  1996 at an  estimated  cost of $2.8  million and plans to
drill 64 wells and  perform 35  workovers  or  recompletions  during  1997 at an
estimated cost of $22.2 million.

         Low Cost  Operations.  The Company  seeks to maintain low operating and
G&A  expenses per BOE by operating a majority of its  producing  properties  and
related assets and by using contract personnel to assist with the development or
evaluation  of  producing  properties  and related  assets.  As a result of this
strategy, the Company's EBITDA Margin has consistently improved since 1991, even
in years with depressed  commodity prices. From the year ended December 31, 1991
to,  on a pro forma  basis,  the nine  months  ended  September  30,  1996,  the
Company's  direct operating and G&A expenses per BOE have decreased by 55.4% and
87.8%, respectively, resulting in an improvement in EBITDA Margin as illustrated
below:

         Focused  Exploration  Activity.  The Company allocates a portion of its
capital  budget to the  drilling of  exploratory  wells which have high  reserve
potential.  The Company  believes that by devoting a relatively  small amount of
capital to high impact,  high risk projects while  reserving the majority of its
available capital for development projects, it can reduce its risk profile while
still  benefiting  from the potential for  significant  reserve  additions.  See
"Business -- Primary Operating Areas -- Exploration Opportunities."

                               RECENT ACQUISITIONS

        The Company has recently acquired CGGS, the Wyoming Properties, Portilla
and Happy,  East White Point and Stedman Island for an aggregate  purchase price
of  approximately  $176.2  million  (the  "Recent  Acquisitions").  The  Company
believes that each of the Recent  Acquisitions  is consistent with the Company's
acquisition strategy.

CGGS

        In November  1996,  Canadian  Abraxas  acquired 100% of the  outstanding
capital stock of CGGS,  after the  consummation  of the sale of the Nevis Plant,
for  CDN$126.4   million,   or  approximately   U.S.$94.8   million,   including
approximately $8.3 million for CGGS' working capital.

        As a result,  Canadian  Abraxas  owns  producing  properties  in western
Canada  consisting  primarily of natural gas  reserves  (the  "Canadian  Abraxas
Properties") and interests  ranging from 10% to 100% in 197 miles of natural gas
gathering systems and 11 natural gas processing plants or compression facilities
(the "Canadian Abraxas Plants"), four of which are operated by Canadian Abraxas.
The  Canadian  Abraxas  Properties  consist of 154,968  gross acres  (86,327 net
acres) and 120 gross wells (68.8 net  wells),  48 of which  operated by Canadian
Abraxas.  As of September 1, 1996,  the Canadian  Abraxas  Properties  had total
proved  reserves of 10,821 MBOE (91.8%  natural gas) with an aggregate  PV-10 of
$46.4 million, 82.4% of which was attributable to proved developed reserves. The
Canadian  Abraxas  Plants had aggregate net natural gas  processing  capacity of
98.5 MMcf per day at September 1, 1996. For the nine months ended  September 30,
1996, the Canadian Abraxas Plants processed an average of 182.8 gross MMcf (65.7
net  MMcf)  of  natural  gas per day,  of which  19.6%  (39.7%  net) was  custom
processed for third parties.  For the nine months ended  September 30, 1996, the
Canadian  Abraxas   Properties  and  the  Canadian  Abraxas  Plants  would  have
contributed $10.3 million of EBITDA to the Company on a pro forma basis.

         The  Company  believes  that  the  Canadian  Abraxas   Properties  have
significant,  quantifiable  development  potential which can be realized through
exploitation  and development.  The Company believes that processing  volumes at
the Canadian Abraxas Plants can be increased due to unutilized gross natural gas
processing  throughput  capacity at the plants of approximately  69.5 MMcf (32.4
net MMcf) of natural  gas per day.  The Company  intends to utilize  this excess
capacity by seeking to process additional natural gas volumes from third parties
and from increased production from the Canadian Abraxas Properties. In addition,
the Company believes that expected increases in the demand for natural gas from,
Alberta,  Canada will help to reduce the existence of basis differentials in the
pricing of natural gas  produced in this area.  The  Company  believes  that its
ownership of the Canadian  Abraxas  Properties  and the Canadian  Abraxas Plants
will afford it a competitive  advantage  relative to other area operators due to
the  Company's  preferential  access to the natural gas  processing  capacity at
these facilities.

        Immediately after the acquisition of CGGS, the Company  amalgamated CGGS
with Canadian  Abraxas,  and Canadian  Abraxas,  being the name of the surviving
entity,  used the net  proceeds  from the sale of the Nevis  Plant to retire the
outstanding debentures of CGGS. In addition,  Canadian Abraxas intends to sell a
10% working interest in the Canadian Abraxas Properties and the Canadian Abraxas
Plants to Cascade,  in  connection  with the  Company's  plan to  integrate  the
operations of the Canadian  Abraxas  Properties and the Canadian  Abraxas Plants
into the existing  operations  of Cascade Oil & Gas Ltd.,  one of the  Company's
Canadian  subsidiaries  ("Cascade").  The Company has identified  potential cost
savings through  anticipated  decreases in the G&A expenses of CGGS, which would
have amounted to approximately  $380,000 for the nine months ended September 30,
1996, on a pro forma basis.  See the unaudited Pro Forma  Financial  Information
and the notes thereto included elsewhere in this Prospectus.

THE WYOMING PROPERTIES

        On September 30, 1996, the Company  acquired  producing  properties with
total proved  reserves of 9,935 MBOE (68.5% natural gas) as of June 30, 1996, in
the Wamsutter area of southwestern Wyoming (the "Wyoming  Properties") for $47.5
million in cash,  before adjustment for accrual of net revenue and interest from
April 1, 1996 to September 30, 1996.  The Wyoming  Properties  consist of 19,587
gross acres (14,091 net acres) and 25 gross wells (20.4 net wells),  22 of which
are  operated  by  the  Company.  In  addition,  the  Company  acquired  various
overriding  royalty  interests in four wells. As of June 30, 1996, the aggregate
PV-10 of the Wyoming Properties was $30.3 million (based, in part, on an assumed
natural gas price of $1.07 per Mcf),  97.3% of which was  attributable to proved
developed  reserves.  For the nine months ended  September 30, 1996, the Wyoming
Properties would have contributed $5.4 million of EBITDA to the Company on a pro
forma basis.  As of September 30, 1996, the Company had recorded the preliminary
net purchase price of $45.9 million to its crude oil and natural gas properties.

        Management   believes  that  the  Wyoming  Properties  have  significant
development  potential  which will enable the Company to increase  its cash flow
from operations and reserve base without significant capital  expenditures.  The
Company intends to exploit this development potential through the more efficient
use of compression and gathering  facilities,  low cost recompletions of various
behind-pipe  zones and drilling of infill  development  wells on closer spacing.
The Company has drilled two wells on the Wyoming  Properties since September 30,
1996.  Additionally,  the  Company has  identified  potential  exploitation  and
development  opportunities  which  it  believes  may have up to  15,400  MBOE of
additional  reserves.  The Wyoming Properties are  geographically  concentrated,
thereby  enabling  the  Company  to operate  the  properties  without  incurring
additional  G&A  expenses.  In  addition,  the Company  believes  that  expected
improvements in the transportation  infrastructure and an increase in the demand
for natural gas from  southwestern  Wyoming will help to reduce the existence of
basis differentials in the pricing of natural gas produced in the area.

PORTILLA AND HAPPY

        In November 1996, the Company  acquired a 75% partnership  interest (the
"Partnership  Interest") in Portilla-1996,  L.P. (the  "Partnership")  for $27.6
million,  including the repayment of certain  indebtedness before adjustment for
the accrual of net revenue to the closing date. The Company previously owned the
remaining 25% interest in the Partnership.  The Partnership owned a 100% working
interest  in the  Portilla  Field,  located in the Texas Gulf Coast  region (the
"Portilla  Field"), a 100% interest in a natural gas processing plant located at
the Portilla Field (the "Portilla Plant" and,  together with the Portilla Field,
"Portilla")  and a 12%  working  interest  in the Happy  Field,  located  in the
Permian Basin of west Texas ("Happy"). Portilla and Happy consist of 1,405 gross
acres  (1,115  net  acres) and 78 gross  wells (52 net  wells),  61 of which are
operated  by the  Company.  As of June 30,  1996,  Portilla  and Happy had total
proved  reserves of 4,314 MBOE (18.4%  natural gas) with an  aggregate  PV-10 of
$30.2 million, 99.8% of which was attributable to proved developed reserves. The
Portilla Plant had natural gas processing  capacity of  approximately  20.0 MMcf
per day at September 30, 1996.  During the nine months ended September 30, 1996,
the Portilla Plant processed an average of 18.2 MMcf of natural gas per day. For
the nine  months  ended  September  30,  1996,  Portilla  and Happy  would  have
contributed  an additional  $3.8 million of EBITDA to the Company on a pro forma
basis.

        The  Company  previously  owned a 50%  interest  in  Portilla  and a 12%
working  interest in Happy.  In March 1996,  the Company  sold its  interests in
Portilla and Happy to Acco, LLC ("Acco") for net  consideration of $15.6 million
(the "Acco Sale").  Acco  subsequently  obtained the release of a 50% overriding
royalty interest in Portilla  previously  owned by the Commingled  Pension Trust
Fund (Pension II), the trustee of which is Morgan  Guaranty Trust Company of New
York (the "Pension  Fund"),  and Acco then contributed its interests in Portilla
and Happy to the Partnership in return for the Partnership Interest. The Company
continued  to operate  Portilla  subsequent  to the Acco Sale.  See  "Business -
Recent Acquisitions -- Portilla and Happy."

EAST WHITE POINT AND STEDMAN ISLAND

        In November 1996, the Company obtained the release of the 50% overriding
royalty  interests in the East White Point Field,  San Patricio  Country,  Texas
("East  White  Point")  and the  Stedman  Island  Field,  Nueces  County,  Texas
("Stedman Island") from the Pension Fund for $9.3 million, before adjustment for
accrual of net revenue  from August 1, 1996 to November  27,  1996.  The Pension
Fund's interest in East White Point and Stedman Island  consisted of 3,723 gross
acres  (1,256  net acres) and 25 gross  wells (6.5 net  wells),  15 of which are
operated  by the  Company.  As of June 30,  1996,  East White  Point and Stedman
Island had total  proved  reserves  of 5,304 MBOE  (62.5%  natural  gas) with an
aggregate  PV-10 of $29.4  million,  71.7% of which was  attributable  to proved
developed reserves.  The East White Point natural gas processing plant, a modern
cyrogenic plant with capacity of approximately 25.0 MMcf of natural gas per day,
extracted  approximately  679  Bbls of NGLs per day for the  nine  months  ended
September 30, 1996.

Change of Control                  Upon a Change of  Control,  each  holder will
                                   have the  right to  require  the  Issuers  to
                                   repurchase   such   holder's   Notes   at   a
                                   redemption   price   equal  to  101%  of  the
                                   principal  amount  thereof  plus  accrued and
                                   unpaid interest to the date of repurchase. In
                                   addition,  the Issuers  will be  obligated to
                                   offer to repurchase  the Notes at 100% of the
                                   principal  amount  thereof  plus  accrued and
                                   unpaid  interest to the date of redemption in
                                   the event of certain asset sales.

Guarantees                         The   Notes   will   be    guaranteed    (the
                                   "Guarantees")  on a  senior  basis by each of
                                   the  Subsidiary  Guarantors.  The  Guarantees
                                   will be general unsecured  obligations of the
                                   Subsidiary  Guarantors  and  will  rank  pari
                                   passu to all  unsubordinated  indebtedness of
                                   the  Subsidiary  Guarantors.  The  Guarantees
                                   will be effectively  subordinated in right of
                                   payment  to  secured   indebtedness   of  the
                                   Subsidiary Guarantors.

Certain Covenants                  The   Indenture   governing  the  Notes  (the
                                   "Indenture")  will contain certain  covenants
                                   that  limit the  ability of the  Issuers  and
                                   their  Restricted  Subsidiaries  (as  defined
                                   herein)  to,   among  other   things,   incur
                                   additional  indebtedness,  pay  dividends  or
                                   make  certain  other   restricted   payments,
                                   consummate  certain  asset sales,  enter into
                                   certain  transactions with affiliates,  incur
                                   liens,  impose restrictions on the ability of
                                   a Restricted  Subsidiary  to pay dividends or
                                   make  certain  payments  to the  Issuers  and
                                   their  Restricted   Subsidiaries,   merge  or
                                   consolidate  with any  other  person or sell,
                                   assign, transfer,  lease, convey or otherwise
                                   dispose  of all or  substantially  all of the
                                   assets of either of the Issuers.

            EXCHANGE OFFER; REGISTRATION RIGHTS; ADDITIONAL INTEREST

        In the  Registration  Rights  Agreement,  the Issuers agreed (i) to file
within 45 days after the Issue Date, and to cause to become effective within 120
days after the Issue Date, a registration statement with respect to the Exchange
Offer, and (ii) upon the Exchange Offer Registration  Statement's being declared
effective, to offer the Exchange Notes in exchange for surrender of the Series A
Notes.  If the Issuers do not comply with their  registration  obligations  in a
timely manner,  they will be required to pay additional interest (in addition to
the  scheduled  payment  of  interest)  during  the first 90 day  period of such
default in an amount  equal to 0.50% per annum at the end of such 90 day period.
The amount of the additional  interest will increase by an additional  0.50% per
annum for each  subsequent  90 day period  until such  obligations  are complied
with, up to a maximum amount of additional  interest of 2.00% per annum.  In the
event that  applicable  interpretations  of the staff of the  Commission  do not
permit the Issuers to effect the Exchange  Offer, or if for any other reason the
Exchange  Offer is not  consummated  within  150 days of the Issue  Date,  or if
certain  holders of the Series A Notes are not  permitted to receive the benefit
of the  Exchange  Offer,  the  Issuers  will use their best  efforts to cause to
become  effective a shelf  registration  statement with respect to the resale of
the Series A Notes and to keep such shelf registration statement effective until
the earlier of three years after its effective  date and such time as all of the
Series A Notes have been sold thereunder.

data of the Company for the five years ended  December 31,  1995,  and as of and
for the nine months ended  September 30, 1995 and 1996,  which have been derived
from the Company's  consolidated  financial  statements and unaudited historical
and pro forma financial data. The pro forma data give effect to the consummation
of the  Transactions.  The unaudited Pro Forma Condensed  Balance Sheet reflects
such  adjustments as if the Transactions had occurred at September 30, 1996, and
the unaudited Pro Forma Statements of Operations for the year ended December 31,
1995 and for the nine months ended  September 30, 1996 reflect such  adjustments
as if the  Transactions  had  occurred  on January 1, 1995 and  January 1, 1996,
respectively.  The historical  consolidated  financial data of the Company as of
and for the nine months ended September 30, 1995 and 1996 have been derived from
the Company's interim consolidated financial statements which, in the opinion of
management  of the Company,  have been prepared on the same basis as the audited
consolidated  financial  statements and include all  adjustments  (consisting of
only normal  recurring  adjustments)  necessary for a fair  presentation  of the
financial data for such periods. The information in this table should be read in
conjunction with  "Management's  Discussion and Analysis of Financial  Condition
and  Results  of  Operations,"   "Selected  Consolidated  Financial  Data,"  the

                                  RISK FACTORS

        Prospective investors should carefully consider the following factors in
addition to the other information in this Prospectus before making an investment
in the Notes offered hereby.

HIGH DEGREE OF LEVERAGE

        As adjusted for the  consummation  of the  Transactions,  the  Company's
total debt and stockholders' equity would have been approximately $215.1 million
and $36.2 million, respectively, as of September 30, 1996. See "Capitalization."
In addition,  the Company has entered into the New Credit Facility,  under which
the Company's  borrowing  capacity is an initial maximum of up to $20.0 million.
For the year ended  December  31, 1995 and the nine months ended  September  30,
1996, on a pro forma basis, the Company's ratio of EBITDA to fixed charges would
have been  1.21x and 1.53x,  respectively,  and its ratio of  earnings  to fixed
charges  would have been  inadequate to cover fixed charges by $16.9 million and
$8.7 million, respectively. The Company intends to incur additional indebtedness
in the future in connection with acquiring,  developing and exploiting producing
properties,  although the Company's ability to incur additional indebtedness may
be  limited  by the terms of the  Indenture  and the New  Credit  Facility.  See
"Description of the Notes,"  "Management's  Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital  Resources"  and the
unaudited  Pro  Forma  Financial  Information  and the  notes  thereto  included
elsewhere in this Prospectus

        The Company's level of indebtedness  will have several important effects
on its future  operations  including (i) a substantial  portion of the Company's
cash flow from  operations  will be  dedicated to the payment of interest on its
indebtedness  and will not be  available  for  other  purposes;  (ii)  covenants
contained in the  Company's  debt  obligations  will require the Company to meet
certain financial tests and other  restrictions  which will limit its ability to
borrow  additional  funds or to dispose  of assets and may affect the  Company's
flexibility in planning for, and reacting to, changes in its business, including
possibly  limiting  acquisition  activities;  and (iii) the Company's ability to
obtain  additional  financing  in  the  future  for  working  capital,   capital
expenditures,  acquisitions,  interest payments,  scheduled  principal payments,
general corporate purposes or other purposes may be limited. See "Description of
the Notes --  Certain  Covenants  --  Limitation  on  Incurrence  of  Additional
Indebtedness" and "Management's  Discussion and Analysis of Financial  Condition
and Results of Operations - Liquidity and Capital Resources."

        The Company's ability to meet its debt service obligations and to reduce
its total indebtedness will be dependent upon the Company's future  performance,
which will be subject to general economic conditions and to financial,  business
and other  factors  affecting the  operations of the Company,  many of which are
beyond  its  control.  Based  upon  the  current  level  of  operations  and the
historical  production of the producing  properties and related assets currently
owned by the Company, the Company believes that its cash flow from operations as
well  as  borrowing  capabilities  will be  adequate  to  meet  its  anticipated
requirements  for working  capital,  capital  expenditures,  interest  payments,
scheduled  principal  payments and general  corporate or other  purposes for the
foreseeable  future.  See the unaudited Pro Forma Financial  Information and the
notes thereto included elsewhere in this Prospectus,  the Company's Consolidated
Financial Statements and the notes thereto included elsewhere in this Prospectus
and "Management's  Discussion and Analysis of Financial Condition and Results of
Operations  -Liquidity  and  Capital  Resources."  No  assurance  can be  given,
however,  that the  Company's  business will continue to generate cash flow from
operations at or above current levels or that the  historical  production of the
producing  properties and related assets  currently  owned by the Company can be
sustained  in the future.  If the  Company is unable to generate  cash flow from
operations  in the future to service its debt,  it may be required to  refinance
all or a portion of its existing debt or to obtain additional  financing.  There
can be no  assurance  that  such  refinancing  would  be  possible  or that  any
additional  financing could be obtained.  In addition,  the Notes are subject to
certain limitations on redemption.  See "Description of the Notes -- Redemption"
and "Management's  Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."



<PAGE>


RANKING OF INDEBTEDNESS

        The Notes will be general unsecured  obligations of the Issuers and will
rank pari passu in right of payment to all  existing  and future  unsubordinated
indebtedness  of the  Issuers  and  senior  in right of  payment  to all  future
subordinated  indebtedness  of the  Issuers.  In  addition,  the  Notes  will be
unconditionally  guaranteed,  jointly and  severally,  by each of the Subsidiary
Guarantors.  The  Guarantees  will  be  general  unsecured  obligations  of  the
Subsidiary  Guarantors  and will  rank  pari  passu in right of  payment  to all
existing and future unsubordinated indebtedness of the Subsidiary Guarantors and
senior in right of payment to all present and future  subordinated  indebtedness
of  the  Subsidiary   Guarantors.   However,   the  Notes  will  be  effectively
subordinated  to  secured   indebtedness  of  the  Issuers  and  the  Subsidiary
Guarantors to the extent of the value of the assets securing such  indebtedness.
As of September 30, 1996, on a pro forma basis,  the Issuers and the  Subsidiary
Guarantors  would have had $215.1 million of indebtedness  outstanding,  none of
which would have been secured,  and $20.0 million of availability  under the New
Credit  Facility,  which  borrowings  will  be  secured.  See  "Capitalization,"
"Description  of  the  Notes"  and  "Management's  Discussion  and  Analysis  of
Financial   Condition   and  Results  of  Operations  -  Liquidity  and  Capital
Resources."

REPURCHASE OF NOTES UPON A CHANGE OF CONTROL

        Upon the  occurrence  of a Change of Control,  the Issuers must offer to
purchase all of the Notes then  outstanding at a purchase price equal to 101% of
the principal  amount thereof,  plus accrued interest to the date of purchase (a
"Change of Control Offer"). See "Description of the Notes --Change of Control."

        Prior to  commencing  such an  offer to  purchase,  the  Issuers  may be
required  to (i)  repay in full  all  indebtedness  of the  Issuers  that  would
prohibit  the  repurchase  of the  Notes,  including  that  under the New Credit
Facility,  or (ii) obtain any requisite consent to permit the repurchase.  See "
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations  - Liquidity  and Capital  Resources."  If the Issuers were unable to
repay all of such indebtedness or were unable to obtain the necessary  consents,
then the  Issuers  would be  unable  to offer to  repurchase  the Notes and such
failure would  constitute an Event of Default under the Indenture.  There can be
no assurance that the Issuers will have  sufficient  funds available at the time
of any Change of Control to repurchase the Notes.

        The events that  require a Change of Control  Offer under the  Indenture
may also constitute events of default under the New Credit Facility. Such events
may permit the lenders under such debt  instruments to accelerate the payment of
the debt and,  if the debt is not  paid,  to  commence  litigation  which  could
ultimately result in a sale of substantially all of the assets of the Company to
satisfy  the debt,  thereby  limiting  the  Company's  ability  to raise cash to
repurchase the Notes and reducing the practical benefit of the offer to purchase
provisions to the holders of the Notes.

NET LOSSES

        The  Company  has  experienced  recurring  losses.  For the years  ended
December 31, 1992,  1993, 1994 and 1995, and the nine months ended September 30,
1996,  the Company  recorded  net losses of $4.0  million,  $2.4  million,  $2.4
million,  $1.2  million  and  $0.2  million,   respectively.  See  "Management's
Discussion and Analysis of Financial  Condition and Results of  Operations"  and
the Company's  Consolidated  Financial Statements and the notes thereto included
elsewhere in this Prospectus.

INDUSTRY CONDITIONS; IMPACT ON COMPANY'S PROFITABILITY

        The  Company's  revenue,  profitability  and  future  rate of growth are
substantially  dependent upon  prevailing  prices for crude oil and natural gas.
Crude oil and natural gas prices can be  extremely  volatile and in recent years
have been depressed by excess total domestic and imported  supplies.  Prices are
also  affected  by actions of state and local  agencies,  the United  States and
foreign  governments and international  cartels.  While prices for crude oil and
natural gas  increased  during the fourth  quarter of 1995 and remained at these
levels  during  the first  half of 1996,  there can be no  assurance  that these
levels for crude oil and natural  gas prices can be  sustained.  These  external
factors and the  volatile  nature of the energy  markets  make it  difficult  to
estimate future prices of crude oil and natural gas. Any substantial or extended
decline in the prices of crude oil and natural gas would have a material adverse
effect on the Company's financial condition and results of operations, including
reduced cash flow and  borrowing  capacity.  All of these factors are beyond the
control of the  Company.  Sales of crude oil and  natural  gas are  seasonal  in
nature,  leading  to  substantial  differences  in cash  flow at  various  times
throughout the year.  Federal and state  regulation of crude oil and natural gas
production and transportation,  general economic  conditions,  changes in supply
and  changes  in demand all could  adversely  affect  the  Company's  ability to
produce and market its crude oil and  natural  gas.  If market  factors  were to
change  dramatically,  the financial impact on the Company could be substantial.
The  availability of markets and the volatility of product prices are beyond the
control of the Company and thus represent a significant risk.

        In addition,  declines in crude oil and natural gas prices might,  under
certain  circumstances,  require a write-down of the book value of the Company's
crude oil and natural gas properties.  If such declines were severe enough, they
could result in the occurrence of an event of default under the Notes or the New
Credit  Facility that could require the sale of some of the Company's  producing
properties under  unfavorable  market  conditions or require the Company to seek
additional  equity  capital.  In  addition,  the  Indenture  and the New  Credit
Facility contain certain restrictions on certain sales of assets by the Company.
See  "Description  of the Notes" and  "Management's  Discussion  and Analysis of
Financial   Condition   and  Results  of  Operations  -  Liquidity  and  Capital
Resources."

        In order to manage its  exposure to price risks in the  marketing of its
crude oil and natural  gas, the Company from time to time has entered into fixed
price delivery contracts,  financial swaps and crude oil and natural gas futures
contracts as hedging devices. To ensure a fixed price for future production, the
Company may sell a futures  contract  and  thereafter  either (i) make  physical
delivery of crude oil or natural gas to comply with such  contract or (ii) buy a
matching futures contract to unwind its futures position and sell its production
to a customer.  Such  contracts  may expose the Company to the risk of financial
loss in certain circumstances, including instances where production is less than
expected,  the Company's  customers  fail to purchase or deliver the  contracted
quantities of crude oil or natural gas, or a sudden, unexpected event materially
impacts  crude oil or natural gas prices.  Such  contracts may also restrict the
ability of the Company to benefit  from  unexpected  increases  in crude oil and
natural gas prices.

RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS

        The Indenture and the New Credit  Facility  will  restrict,  among other
things, the Company's ability to incur additional indebtedness, incur liens, pay
dividends or make certain other restricted  payments,  consummate  certain asset
sales,  enter into certain  transactions  with affiliates,  merge or consolidate
with any other  person or sell,  assign,  transfer,  lease,  convey or otherwise
dispose of all or substantially  all of the assets of the Company.  In addition,
the New Credit Facility will contain additional and more restrictive  covenants.
The  Indenture  and the New Credit  Facility  also will  require  the Company to
maintain  specified  financial  ratios and satisfy certain  financial tests. The
Company's  ability to meet such  financial  ratios and tests may be  affected by
events beyond its control,  and there can be no assurance  that the Company will
meet such ratios and tests. See "Description of the Notes -- Certain  Covenants"
and "Management's  Discussion and Analysis of Financial Condition and Results of
Operations  -  Liquidity  and  Capital  Resources."  A  breach  of any of  these
covenants  could result in a default under the  Indenture  and/or the New Credit
Facility.  Upon the  occurrence  of an event of  default  under  the New  Credit
Facility,  the lenders thereunder could elect to declare all amounts outstanding
under the New Credit Facility, together with accrued interest, to be immediately
due and payable. If the Company were unable to repay those amounts, such lenders
could  proceed   against  the   collateral   granted  to  them  to  secure  that
indebtedness.  If the  lenders  under the New  Credit  Facility  accelerate  the
payment of such  indebtedness,  there can be no assurance that the assets of the
Company  would be sufficient  to repay in full such  indebtedness  and the other
indebtedness  of the  Company,  including  the Notes.  Substantially  all of the
Company's  U.S.  assets,  including,  without  limitation,  working  capital and
interests in producing  properties and related assets owned by the Company,  and
the proceeds  thereof will be pledged as security under the New Credit Facility.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."

SUBSTANTIAL CAPITAL REQUIREMENTS

        The  Company  makes,  and will  continue  to make,  substantial  capital
expenditures for the  acquisition,  exploitation,  development,  exploration and
production of crude oil and natural gas reserves.  Historically, the Company has
financed  these  expenditures  primarily  with cash flow from  operations,  bank
borrowings and the offering of its equity securities.  The Company believes that
it will have  sufficient  capital to finance planned  capital  expenditures.  If
revenue or the Company's  borrowing base under the New Credit Facility  decrease
as a result of lower crude oil and natural gas prices, operating difficulties or
declines in reserves,  the Company may have limited  ability to finance  planned
capital  expenditures  in the future.  There can be no assurance that additional
debt or equity  financing or cash  generated by operations  will be available to
meet these requirements.  See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

INTEGRATION OF OPERATIONS; FOREIGN OPERATIONS

        The Company's future  operations and earnings will be largely  dependent
upon the Company's  ability to integrate the operations of Canadian  Abraxas and
the  Wyoming  Properties  into  the  current  operations  of  the  Company.  The
operations of Canadian Abraxas and the Wyoming Properties vary in geography from
that of the Company's current operations,  and with respect to Canadian Abraxas,
to some extent, in scope and type, from the Company's current operations.  There
can be no assurance that the Company will be able to successfully integrate such
operations  with  those of the  Company,  and a  failure  to do so would  have a
material  adverse  effect  on  the  Company's  financial  position,  results  of
operations and cash flows. Additionally, although the Company does not currently
have any specific acquisition plans other than the Recent Acquisitions, the need
to focus management's attention on integration of the new operations, as well as
other  factors,   may  limit  the  Company's  ability  to  successfully   pursue
acquisitions or other opportunities  related to its business for the foreseeable
future. Also,  successful  integration of operations will be subject to numerous
contingencies,   some  of  which  are   beyond   management's   control.   These
contingencies include general and regional economic conditions, prices for crude
oil and natural gas, competition and changes in regulation.  Even if the Company
were successful in integrating  the new  operations,  the acquisition of CGGS in
particular will significantly increase the Company's dependence on international
operations,  specifically  those in Canada,  and  therefore  the Company will be
subject to various additional political, economic and other uncertainties. Among
other  risks,  the  Company's  operations  will  be  subject  to  the  risks  of
restrictions  on  transfers  of funds,  export  duties and quotas,  domestic and
international  customs and tariffs,  and  changing  taxation  policies,  foreign
exchange  restrictions,  political conditions and governmental  regulations.  In
addition,  the  Company  will  receive a  substantial  portion of its revenue in
Canadian  dollars.  As a  result,  fluctuations  in the  exchange  rates  of the
Canadian  dollar with respect to the U.S. dollar could have an adverse effect on
the Company's  financial  position,  results of operations  and cash flows.  The
Company may from time to time engage in hedging programs  intended to reduce the
Company's exposure to currency fluctuations.

        To obtain  volumes  of  committed  natural  gas  reserves  to supply the
Canadian  Abraxas Plants,  Canadian Abraxas will contract to process natural gas
with various producers.  Future natural gas supplies available for processing at
the Canadian Abraxas Plants will be affected by a number of factors that are not
within the  Company's  control,  including  the  depletion  rate of natural  gas
reserves  currently  connected to the Canadian  Abraxas Plants and the extent of
exploration  for,  production and  development of, and demand for natural gas in
the areas in which Canadian Abraxas will operate.  Long-term  contracts will not
protect  Canadian  Abraxas from shut-ins or supply  curtailments  by natural gas
suppliers.  Although CGGS was  historically  successful in  contracting  for new
natural gas  supplies  and in  renewing  natural  gas supply  contracts  as they
expired,  there is no assurance that Canadian Abraxas will be able to do so on a
similar basis in the future.

OPERATING HAZARDS; UNINSURED RISKS

        The nature of the crude oil and natural gas  business  involves  certain
operating  hazards  such as crude  oil and  natural  gas  blowouts,  explosions,
encountering formations with abnormal pressures,  cratering and crude oil spills
and fires,  any of which could result in damage to or  destruction  of crude oil
and natural gas wells,  destruction of producing  facilities,  damage to life or
property, suspension of operations,  environmental damage and possible liability
to the Company.  In accordance with customary  industry  practices,  the Company
maintains  insurance  against some, but not all, of such risks and some, but not
all,  of such  losses.  The  occurrence  of such an event not fully  covered  by
insurance  could have a material  adverse effect on the financial  condition and
results of operations of the Company.



<PAGE>


COMPETITION

        The Company  encounters strong  competition from major oil companies and
independent  operators in acquiring  properties  and leases for the  exploration
for, and production of, crude oil and natural gas.  Competition is  particularly
intense with respect to the acquisition of desirable  undeveloped  crude oil and
natural gas properties.  The principal competitive factors in the acquisition of
such undeveloped crude oil and natural gas properties include the staff and data
necessary  to  identify,  investigate  and  purchase  such  properties,  and the
financial  resources  necessary to acquire and develop such properties.  Many of
the  Company's  competitors  have  financial  resources,  staff  and  facilities
substantially  greater than those of the Company.  In addition,  the  producing,
processing and marketing of crude oil and natural gas is affected by a number of
factors which are beyond the control of the Company,  the effect of which cannot
be accurately predicted.

        The principal raw materials and resources  necessary for the exploration
and production of crude oil and natural gas are leasehold  prospects under which
crude oil and natural gas reserves may be discovered,  drilling rigs and related
equipment to explore for such  reserves and  knowledgeable  personnel to conduct
all phases of crude oil and natural gas operations. The Company must compete for
such raw  materials  and  resources  with both major  crude oil and  natural gas
companies and independent  operators.  Although the Company believes its current
operating  and  financial  resources  are adequate to preclude  any  significant
disruption of its operations in the immediate future, the continued availability
of such materials and resources to the Company cannot be assured.

        The Company will face significant  competition for obtaining  additional
natural gas supplies for  gathering  and  processing  operations,  for marketing
NGLs, residue gas, helium,  condensate and sulfur, and for transporting  natural
gas  and  liquids.  The  Company's  principal  competitors  will  include  major
integrated oil companies and their  marketing  affiliates and national and local
gas gatherers,  brokers,  marketers and distributors of varying sizes, financial
resources  and  experience.  Certain  competitors,  such as major  crude oil and
natural gas companies,  have capital  resources and control  supplies of natural
gas substantially greater than the Company. Smaller local distributors may enjoy
a marketing advantage in their immediate service areas.

        The Company  will  compete  against  other  companies in its natural gas
processing  business both for supplies of natural gas and for customers to which
it will  sell its  products.  Competition  for  natural  gas  supplies  is based
primarily  on  location  of natural  gas  gathering  facilities  and natural gas
gathering plants,  operating  efficiency and reliability and ability to obtain a
satisfactory  price for products  recovered.  Competition for customers is based
primarily on price and delivery capabilities.

RELIANCE ON ESTIMATES OF PROVED RESERVES AND FUTURE NET REVENUE

        There are numerous  uncertainties  inherent in estimating  quantities of
proved  reserves and in projecting  future rates of production and the timing of
development  expenditures,  including  many  factors  beyond the  control of the
Company.  The reserve data included in this Prospectus represent only estimates.
In addition,  the  estimates of future net revenue from proved  reserves and the
present value thereof are based upon certain assumptions about future production
levels,  prices,  and  costs  that may not prove to be  correct  over  time.  In
particular,  estimates of crude oil and natural gas reserves, future net revenue
from  proved  reserves  and the PV-10  thereof for the crude oil and natural gas
properties  described in this Prospectus are based on the assumption that future
crude oil and  natural  gas prices  remain the same as crude oil and natural gas
prices at June 30, 1996, with respect to Abraxas' existing  properties,  and for
the month of July 1996 with  respect to the  Canadian  Abraxas  Properties.  The
average sales prices as of such dates used for purposes of such  estimates  were
$19.86 per Bbl of crude oil, $14.09 per Bbl of NGLs and $1.27 per Mcf of natural
gas with respect to the  Canadian  Abraxas  Properties,  $21.70 per Bbl of crude
oil,  $9.25 per Bbl of NGLs and $1.07 per Mcf of natural gas with respect to the
Wyoming  Properties,  $19.98  per Bbl of crude  oil,  $14.50 per Bbl of NGLs and
$2.65 per Mcf of natural gas with  respect to Portilla  and Happy and $20.64 per
Bbl of crude oil,  $12.38 per Bbl of NGLs and $2.29 per Mcf of natural  gas with
respect to the Company's other properties in the aggregate.  Also assumed is the
Company's making future capital  expenditures of approximately  $19.7 million in
the aggregate, including $3.4 million on the Wyoming Properties, $1.7 million on
the  Canadian  Abraxas  Properties  and $2.2  million  on  Portilla  and  Happy,
necessary  to develop and realize  the value of proved  undeveloped  reserves on
these properties. Any significant variance in these assumptions could materially
affect the  estimated  quantity  and value of  reserves  set forth  herein.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations  --  Liquidity  and  Capital  Resources"  and  "Business  -- Reserves
Information."

CERTAIN BUSINESS RISKS

        The  Company  intends  to  continue  acquiring  producing  crude oil and
natural gas  properties  or  companies  that own such  properties.  Although the
Company  performs  a review  of the  acquired  properties  that it  believes  is
consistent with industry practices,  such reviews are inherently incomplete.  It
generally is not feasible to review in depth every individual  property involved
in each  acquisition.  Ordinarily,  the Company will focus its review efforts on
the  higher-valued  properties and will sample the remainder.  However,  even an
in-depth  review  of all  properties  and  records  may not  necessarily  reveal
existing  or  potential  problems  nor will it  permit  the  Company  to  become
sufficiently familiar with the properties to assess fully their deficiencies and
capabilities.  Inspections  may not  always  be  performed  on every  well,  and
environmental problems, such as ground water contamination,  are not necessarily
observable even when an inspection is undertaken.  Furthermore, the Company must
rely on information,  including financial, operating and geological information,
provided by the seller of the properties  without being able to verify fully all
such information and without the benefit of knowing the history of operations of
all such properties.

        In addition, a high degree of risk of loss of invested capital exists in
almost all exploration and development  activities which the Company undertakes.
No assurance  can be given that crude oil or natural gas will be  discovered  to
replace reserves currently being developed,  produced and sold, or that if crude
oil or natural gas reserves are found, they will be of a sufficient  quantity to
enable the Company to recover the  substantial  sums of money  incurred in their
acquisition,  discovery  and  development.  Drilling  activities  are subject to
numerous risks, including the risk that no commercially  productive crude oil or
natural gas reservoirs will be encountered. The cost of drilling, completing and
operating wells is often uncertain.  The Company's  operations may be curtailed,
delayed or cancelled as a result of numerous  factors  including title problems,
weather conditions,  compliance with governmental  requirements and shortages or
delays in the delivery of equipment.  The availability of a ready market for the
Company's  natural gas  production  depends on a number of  factors,  including,
without  limitation,  the demand for and supply of natural gas, the proximity of
natural gas reserves to pipelines, the capacity of such pipelines and government
regulations.

DEPLETION OF RESERVES

        The  rate of  production  from  crude  oil and  natural  gas  properties
declines as reserves  are  depleted.  Except to the extent the Company  acquires
additional   properties   containing   proved  reserves,   conducts   successful
exploration  and  development   activities  or,  through  engineering   studies,
identifies  additional  behind-pipe zones or secondary  recovery  reserves,  the
proved  reserves of the Company will decline as reserves  are  produced.  Future
crude oil and natural gas  production  is therefore  highly  dependent  upon the
Company's  level of success in acquiring  or finding  additional  reserves.  See
"--Certain Business Risks."

        The  Company's  ability to continue to acquire  producing  properties or
companies that own such properties  assumes that major  integrated oil companies
and  independent  oil companies  will continue to divest many of their crude oil
and  natural  gas  properties.  There can be no  assurance,  however,  that such
divestitures  will  continue  or that the Company  will be able to acquire  such
properties at acceptable prices or develop additional reserves in the future. In
addition,  under the terms of the  Indenture  and the New Credit  Facility,  the
Company's ability to obtain additional  financing in the future for acquisitions
and capital expenditures may be limited.

GOVERNMENT REGULATION

        The Company's business is subject to certain federal,  state, provincial
and local laws and regulations  relating to the exploration for and development,
production and marketing of crude oil and natural gas, as well as  environmental
and  safety  matters.  Such laws and  regulations  have  generally  become  more
stringent in recent years,  often imposing greater  liability on a larger number
of potentially  responsible  parties.  Because the requirements  imposed by such
laws and  regulations are frequently  changed,  the Company is unable to predict
the ultimate cost of compliance  with such  requirements.  There is no assurance
that laws and  regulations  enacted in the future will not adversely  affect the
Company's  financial  condition  and results of  operations.  See  "Business  --
Regulatory Matters."

FRAUDULENT CONVEYANCE

        Various  fraudulent  conveyance  laws  enacted  for  the  protection  of
creditors may apply to the Subsidiary Guarantors' issuance of the Guarantees. To
the extent  that a court were to find that (x) a  Guarantee  was  incurred  by a
Subsidiary  Guarantor with actual intent to hinder, delay or defraud any present
or  future  creditor  or (y) such  Subsidiary  Guarantor  did not  receive  fair
consideration or reasonably  equivalent value for issuing its Guarantee and such
Subsidiary Guarantor (i) was insolvent, (ii) was rendered insolvent by reason of
the  issuance  of such  Guarantee,  (iii)  was  engaged  or about to engage in a
business  or  transaction  for which  the  remaining  assets of such  Subsidiary
Guarantor  constituted  unreasonably  small  capital to carry on its business or
(iv)  intended  to incur,  or believed  that it would  incur,  debts  beyond its
ability to pay such debts as they matured,  the court could avoid or subordinate
such Guarantee in favor of the  Subsidiary  Guarantor's  creditors.  Among other
things,  a legal challenge of a Guarantee on fraudulent  conveyance  grounds may
focus on the benefits,  if any, realized by the Subsidiary Guarantor as a result
of the issuance by the Company of the Notes.  To the extent any Guarantees  were
avoided as a fraudulent  conveyance or held  unenforceable for any other reason,
the claims of holders of the Notes in respect of such Subsidiary Guarantor would
be  adversely  affected  and such holders  would,  to such extent,  be creditors
solely of the Company  and any  Subsidiary  Guarantor  whose  Guarantee  was not
avoided or held  unenforceable.  To the extent the claims of the  holders of the
Notes against the issuer of an invalid Guarantee were  subordinated,  they would
be subject to the prior payment of all liabilities of such Subsidiary Guarantor.
There can be no assurance  that,  after  providing for all prior  claims,  there
would be  sufficient  assets to satisfy  the claims of the  holders of the Notes
relating to any voided portion of any of the Guarantees.

        The measure of insolvency  for purposes of the foregoing  considerations
will vary  depending  upon the law  applied  in any such  proceeding.  Under one
measure,  the Subsidiary  Guarantors  may be considered  insolvent if the sum of
their  debts,  including  contingent  liabilities,  were  greater  than the fair
marketable  value of all of their  assets at a fair  valuation or if the present
fair  marketable  value of their  assets were less than the amount that would be
required to pay their  probable  liability on their  existing  debts,  including
contingent liabilities, as they become absolute and mature.

        Based upon financial and other  information,  the Company  believes that
the Notes and the Guarantees are being incurred for proper  purposes and in good
faith and that the Company  and each  Subsidiary  Guarantor  is solvent and will
continue to be solvent after issuing the Notes or its Guarantee, as the case may
be,  will have  sufficient  capital  for  carrying  on its  business  after such
issuance  and will be able to pay its  debts  as they  mature.  There  can be no
assurance,  however, that a court passing on such standards would agree with the
Company.

DEPENDENCE ON KEY PERSONNEl

        The  Company  depends  to a large  extent on Robert  L. G.  Watson,  its
Chairman of the Board, President and Chief Executive Officer, for its management
and business and financial contacts. See "Management." The unavailability of Mr.
Watson would have a materially  adverse  effect on the Company's  business.  The
Company's  success  is also  dependent  upon its  ability  to employ  and retain
skilled  technical  personnel.  While the  Company  has not to date  experienced
difficulties in employing or retaining such  personnel,  its failure to do so in
the future could adversely affect its business.

LIMITATIONS   ON  THE   AVAILABILITY   OF  THE  COMPANY'S  NET  OPERATING   LOSS
CARRYFORWARDS

        As a result of the  acquisition  of certain  partnership  interests  and
crude oil and natural gas properties in 1990 and 1991, an ownership change under
section 382  ("Section  382") of the Internal  Revenue Code of 1986,  as amended
(the "Code"),  occurred in December 1991.  Accordingly,  it is expected that the
use of net operating loss carryforwards  generated prior to December 31, 1991 of
$6.9 million will be limited to  approximately  $235,000 per year.  During 1992,
the Company  acquired  100% of the  outstanding  capital  stock of an  unrelated
corporation.  The use of net operating loss carryforwards of $3.6 million of the
unrelated  corporation  are limited to  approximately  $115,000  per year.  As a
result of the issuance of additional shares of Common Stock for acquisitions and
to raise  capital,  an  additional  ownership  change  occurred in October 1993.
Accordingly,  it is expected  that the use of the $13.4 million of net operating
loss   carryforwards   generated   through  October  1993  will  be  limited  to
approximately $1.0 million per year, subject to the limitations described above,
and $7.2 million in the aggregate. Future changes in ownership may further limit
the  use of  the  Company's  carryforwards.  In  addition  to  the  Section  382
limitations,   uncertainties   exist  as  to  the  future   utilization  of  the
carryforwards  under the criteria set forth in  Financial  Accounting  Standards
Board  ("FASB")  Statement No. 109,  "Accounting  for Income Taxes." The Company
established a valuation  allowance of $5.5 million and $5.7 million for deferred
tax assets at December 31, 1994 and 1995, respectively.

LACK OF PUBLIC MARKET

        There is no existing trading market for the Notes.  Although the Initial
Purchasers have advised the Issuers that they currently  intend to make a market
in the Notes and, if issued, the Exchange Notes, they are not obligated to do so
and they may  discontinue  such  market-making  at any time without  notice.  In
addition,  such market-making  activity may be limited during the Exchange Offer
and the pendency of the Shelf  Registration  Statement (as defined  herein),  if
any. Although the Notes will be eligible for trading in the PORTAL Market, there
can be no assurance as to the  development of any market or the liquidity of any
market that may develop for the Notes or the Exchange Notes.  The Issuers do not
intend to apply for listing or quotation of the Notes on any securities exchange
or stock market.

                          PURPOSE OF THE EXCHANGE OFFER

        In connection  with the initial sale of the Series A Notes,  the Issuers
agreed, subject to certain conditions,  to use their best efforts to conduct the
Exchange Offer pursuant to the terms of the Registration Rights Agreement by and
among  the  Issuers  and  the  Initial  Purchasers  (the  "Registration   Rights
Agreement").  The Registration  Rights Agreement,  pursuant to which the Issuers
agreed,  with  respect  to the  Series  A  Notes  and  subject  to the  Issuers'
determination  that the Exchange  Offer is permitted  under  applicable  law and
Commission  policy, to (i) cause to be filed with the Commission,  no later than
45 days after the Issue Date, a registration  statement under the Securities Act
relating  to the  Exchange  Notes and the  Exchange  Offer,  (ii) use their best
efforts (a) to cause such registration statement to be declared effective by the
Commission  in no event later than 120 days after the Issue  Date,  (b) upon the
effectiveness of such  registration  statement,  to commence the Exchange Offer,
and (c) to cause the Exchange Offer to remain open for a period of not less than
30 days.  The Issuers'  purpose in making the  Exchange  Offer is to comply with
such  agreement and to avoid the increase in interest rate on the Series A Notes
which would occur if the  Exchange  Offer were not duly and timely  consummated.
The Exchange Offer should provide holders of the Series A Notes with the ability
to effect, for federal income tax purposes, a tax-free exchange of such Series A
Notes,  which are subject to trading  limitations,  for Exchange Notes that will
not be subject to such restrictions.

        The  Exchange  Offer  provides  holders  of the  Series A Notes with the
Exchange Notes that will  generally be freely  transferable  by holders  thereof
(other than any holder who is an "affiliate" or "promoter" of the Issuers within
the  meaning of Rule 405 under the  Securities  Act),  who may offer for resale,
resell or otherwise  transfer such Exchange  Notes  without  complying  with the
registration and prospectus  delivery provisions of the Securities Act, provided
that  such  Exchange  Notes are  acquired  in the  ordinary  course of each such
holder's business and such holders have no arrangement or understanding with any
person to participate in a distribution of the Exchange  Notes.  Each holder who
participates  in the  Exchange  Offer will be  required  to  represent  that any
Exchange  Notes  received by it will be acquired in the  ordinary  course of its
business,  that at the time of  consummation  of the Exchange  Offer such holder
will have no arrangement or understanding  with any person to participate in the
distribution  of the  Exchange  Notes  in  violation  of the  provisions  of the
Securities  Act, and that such holder is not an affiliate of the Issuers  within
the meaning of the Securities Act.



<PAGE>


                          RESALE OF THE EXCHANGE NOTES

        With respect to resales of the Exchange Notes,  based on interpretations
by the staff of the  Commission  set forth in no-action  letters issued to third
parties, the Issuers believe that a holder or other person who receives Exchange
Notes,  whether or not such person is the holder (other than a person that is an
"affiliate"  of the Issuers  within the meaning of Rule 405 under the Securities
Act) who receives  Exchange Notes in exchange for Series A Notes in the ordinary
course of business and who is not participating, does not intend to participate,
and has no arrangement or understanding  with any person to participate,  in the
distribution of the Exchange Notes, will be allowed to resell the Exchange Notes
to the public without further  registration under the Securities Act and without
delivering to the purchasers of the Exchange  Notes a prospectus  that satisfies
the  requirements  of Section 10 of the Securities Act.  However,  if any holder
acquires Exchange Notes in the Exchange Offer for the purpose of distributing or
participating  in a distribution of the Exchange Notes,  such holder cannot rely
on the  position of the staff of the  Commission  enunciated  in such  no-action
letters  or  any  similar  interpretive   letters,  and  must  comply  with  the
registration  and prospectus  delivery  requirements of the Securities Act (with
such prospectus  containing the selling  securityholder  information required by
Item 507 of Regulation  S-K under the  Securities  Act) in  connection  with any
resale   transaction,   unless  an  exemption  from  registration  is  otherwise
available.  Further,  each  Participating  Broker-Dealer  that receives Exchange
Notes for its own  account in exchange  for Series A Notes,  where such Series A
Notes  were  acquired  by  such  Participating  Broker-Dealer  as  a  result  of
market-making  activities  or  other  trading  activities,  may  be a  statutory
underwriter and must acknowledge  that it will deliver a prospectus  meeting the
requirements of the Securities Act (which may be this  Prospectus,  as it may be
amended or supplemented from time to time) in connection with any resale of such
Exchange Notes.

        As contemplated by these no-action  letters and the Registration  Rights
Agreement,  each holder accepting the Exchange Offer is required to represent to
the Issuers in the Letter of  Transmittal  that (i) the Exchange Notes are to be
acquired by the holder or the person  receiving such Exchange Notes,  whether or
not such person is the holder,  in the  ordinary  course of  business,  (ii) the
holder or any such other person (other than a  broker-dealer  referred to in the
next  sentence)  is  not  engaging  and  does  not  intend  to  engage,  in  the
distribution  of the Exchange  Notes,  (iii) the holder or any such other person
has no  arrangement  or  understanding  with any  person to  participate  in the
distribution of the Exchange  Notes,  (iv) neither the holder nor any such other
person is an "affiliate" of the Issuers within the meaning of Rule 405 under the
Securities Act, and (v) the holder or any such other person acknowledges that if
such holder or other person  participates  in the Exchange Offer for the purpose
of  distributing  the Exchange  Notes it must comply with the  registration  and
prospectus  delivery  requirements  of the Securities Act in connection with any
resale of the  Exchange  Notes and cannot rely on those  no-action  letters.  As
indicated above, each Participating Broker-Dealer that receives an Exchange Note
for its own account in exchange for the Series A Notes must  acknowledge that it
will deliver a prospectus in connection  with any resale of such Exchange Notes.
For  a  description  of  the  procedures  for  such  resales  by   Participating
Broker-Dealers, see "Plan of Distribution."

                              PLAN OF DISTRIBUTION

        Each  Participating  Broker-Dealer  that receives Exchange Notes for its
own account pursuant to the Exchange Offer must acknowledge that it will deliver
a  prospectus  in  connection  with any  resale  of such  Exchange  Notes.  This
Prospectus,  as it may be amended or supplemented from time to time, may be used
by a  Participating  Broker-Dealer  in connection with resales of Exchange Notes
received  in  exchange  for the Series A Notes  where  such  Series A Notes were
acquired as a result of  market-making  activities or other trading  activities.
The  Issuers  have  agreed  that they will make this  Prospectus,  as amended or
supplemented, available to any Participating Broker-Dealer for use in connection
with any such resale during the period required by the Securities Act.

        The Issuers will not receive any proceeds from any sales of the Exchange
Notes  by   Participating   Broker-Dealers.   The  Exchange  Notes  received  by
Participating  Broker-Dealers  for their own account  pursuant  to the  Exchange
Offer  may be  sold  from  time  to  time  in one or  more  transactions  in the
over-the-counter  market,  in  negotiated  transactions,  through the writing of
options on the Exchange  Notes or a  combination  of such methods of resale,  at
market  prices  prevailing  at the time of  resale,  at prices  related  to such
prevailing  market  prices or  negotiated  prices.  Any such  resale may be made
directly  to the  purchaser  or  through  brokers  or  dealers  who may  receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
Participating  Broker-Dealer  and/or the purchasers of any such Exchange  Notes.
Any  Participating  Broker-Dealer  that  resells  the  Exchange  Notes that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that  participates  in a  distribution  of such Exchange  Notes may be
deemed to be an  "underwriter"  within the meaning of the Securities Act and any
profit on any such resale of Exchange  Notes and any  commissions or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act. The Letter of Transmittal  states that by acknowledging that
it will deliver and by delivering a prospectus,  a  Participating  Broker-Dealer
will not be deemed to admit that it is an  "underwriter"  within the  meaning of
the Securities Act. The Issuers have agreed to pay all expenses  incident to the
Exchange  Offer other than  commissions or concessions of any brokers or dealers
and will  indemnify an Eligible  Holder  (including any  broker-dealer)  against
certain liabilities, including liabilities under the Securities Act.

        The Issuers will promptly send additional  copies of this Prospectus and
any   amendment  or  supplement   to  this   Prospectus  to  any   Participating
Broker-Dealer that requests such documents in the Letter of Transmittal.

                               THE EXCHANGE OFFER

TERMS OF THE OFFER

        The Issuers hereby offer, upon the terms and conditions set forth herein
and in the related Letter of  Transmittal,  to exchange the Exchange Notes for a
like principal amount of the outstanding  Series A Notes. An aggregate of $215.0
million  principal amount of Series A Notes are outstanding.  The Exchange Offer
is not conditioned upon any minimum amount of the Series A Notes being tendered.

        The  Exchange  Offer will  expire at 5:00 p.m.,  New York City time,  on
___________,  199_, unless extended. The term "Expiration Date" means 5:00 p.m.,
New York City time,  on  __________ , 199_,  unless the  Issuers,  in their sole
discretion,  notify the Exchange Agent that the period of the Exchange Offer has
been extended,  in which case the term  "Expiration  Date" means the latest time
and  date on which  the  Exchange  Offer as so  extended  will  expire.  See "--
Expiration and Extension."

        Holders  of the Series A Notes who wish to  exchange  the Series A Notes
for the Exchange Notes and who validly tender the Series A Notes to the Exchange
Agent or  validly  tender the Series A Notes by  complying  with the  book-entry
transfer procedures described below and, in each case, who furnish the Letter of
Transmittal and any other required  documents to the Exchange Agent, will either
have  the  Exchange  Notes  mailed  to them by the  Exchange  Agent  or have the
Exchange  Notes  credited to their  account in  accordance  with the  book-entry
transfer procedures  described below,  promptly after such tender is accepted by
the Issuers.  Subject to the terms and  conditions  of the Exchange  Offer,  the
Series A Notes which have been validly  tendered  prior to the  Expiration  Date
will be  accepted  on or  promptly  after the  Expiration  Date.  Subject to the
applicable  rules of the Commission,  the Issuers,  however,  reserve the right,
prior to the first acceptance of tendered Series A Notes, to delay acceptance of
tendered  Series A Notes,  or to terminate  the Exchange  Offer,  subject to the
provisions of Rule 14e-1(c) under the Exchange Act, which requires that a tender
offeror pay the consideration offered or return the tendered securities promptly
after the termination or withdrawal of a tender offer.

        In  addition,  the Issuers  reserve the right to waive any  condition or
otherwise amend the Exchange Offer in any respect  consistent with the Indenture
and the Registration Rights Agreement prior to the acceptance of tendered Series
A Notes.  If any amendment by the Issuers of the Exchange Offer or waiver by the
Issuers  of  any  condition  thereto   constitutes  a  material  change  in  the
information  previously  disclosed to the holders of Series A Notes, the Issuers
will, in accordance  with the applicable  rules of the  Commission,  disseminate
promptly  disclosure of such change in a manner reasonably  calculated to inform
such  holders  of  such  change.  If it  is  necessary  to  permit  an  adequate
dissemination of information  regarding such material  change,  the Issuers will
extend the Exchange Offer to permit an adequate time for holders of the Series A
Notes to consider the additional information.



<PAGE>


CERTAIN EFFECTS OF THE EXCHANGE OFFER

        Because the Exchange Offer is for any and all Series A Notes, the number
of Series A Notes  tendered and exchanged in the Exchange  Offer will reduce the
principal amount of Series A Notes  outstanding.  As a result,  the liquidity of
any remaining  Series A Notes may be substantially  reduced.  The Series A Notes
are currently  eligible for sale pursuant to Rule 144A through the PORTAL System
of the National  Association  of Securities  Dealers,  Inc.  Because the Issuers
anticipate  that most  holders  of Series A Notes will  elect to  exchange  such
Series A Notes for the Exchange Notes due to the absence of  restrictions on the
resale of the Exchange  Notes under the Securities  Act, the Issuers  anticipate
that the  liquidity  of the market for any  Series A Notes  remaining  after the
consummation of the Exchange Offer may be substantially limited.

EXPIRATION AND EXTENSION

        The  Exchange  Offer will  expire at 5:00 p.m.,  New York City time,  on
__________ , 199_,  unless  extended by the Issuers.  The Exchange  Offer may be
extended by oral or written notice from the Issuers to the Exchange Agent at any
time or from time to time, on or prior to the date then fixed for the expiration
of the Exchange  Offer.  Public  announcement  of any  extension of the Exchange
Offer will be timely made by the Company,  but, unless otherwise required by law
or  regulation,  the Company will not have any  obligation to  communicate  such
public  announcement  other  than by  making a  release  to the Dow  Jones  News
Service.

        The Issuers  reserve the right, in their sole  discretion,  (i) to delay
accepting any Series A Notes,  (ii) to extend the Exchange Offer or (iii) if any
conditions set forth below under  "--Conditions"  shall not have been satisfied,
to terminate the Exchange  Offer by giving oral or written notice of such delay,
extension or  termination to the Exchange  Agent.  Any such delay in acceptance,
extension,  termination or amendment will be followed as promptly as practicable
by oral or written  notice thereof to the  registered  holders.  If the Exchange
Offer is amended in a manner  determined by the Issuers to constitute a material
change,  the  Issuers  will  promptly  disclose  such  amendment  by  means of a
prospectus  supplement that will be distributed to the registered holders of the
Private  Notes,  and the Issuers will extend the Exchange  Offer for a period of
five to ten business days,  depending upon the significance of the amendment and
the manner of disclosure to the registered  holders, if the Exchange Offer would
otherwise expire during such five to ten business day period.

CONDITIONS

        The  Exchange  Offer is subject  to the  following  conditions:  (i) the
Exchange Offer does not violate applicable law or any applicable  interpretation
of the staff of the  Commission,  (ii) no action or  proceeding is instituted or
threatened  in any court or by any  governmental  agency which might  materially
impair the  ability of the  Issuers to proceed  with the  Exchange  Offer and no
material  adverse  development has occurred in any existing action or proceeding
with  respect to the  Issuers  and (iii) all  governmental  approvals  have been
obtained, which approvals the Issuers deem necessary for the consummation of the
Exchange Offer.

REGISTRATION RIGHTS

        On November 14, 1996, the Issuers entered into the  Registration  Rights
Agreement  with the Initial  Purchasers  pursuant to which the Issuers have, for
the benefit of the holders of the Notes,  at the  Issuers'  cost,  agreed to (i)
file the  registration  statement  of which  this  Prospectus  forms a part (the
"Exchange Offer Registration Statement"),  under the Securities Act with respect
to the  Exchange  Offer which  constitutes  the  Issuers'  offer to exchange the
Series A Notes for the Exchange  Notes,  which will have terms  identical in all
material respects to the Series A Notes (except that the Exchange Notes will not
contain terms with respect to transfer restrictions and will not contain certain
provisions relating to an increase in the interest rate which were applicable to
the  Series A Notes in  certain  circumstances  relating  to the  timing  of the
Exchange Offer), and (ii) cause the Exchange Offer Registration  Statement to be
declared  effective  under the  Securities  Act  within 120 days after the Issue
Date.  The  Issuers  will  keep the  Exchange  Offer  open for not less  than 30
calendar days (or longer if required by applicable law) after the date notice of
the Exchange Offer is mailed to the holders of the Series A Notes.

        In  the  event  that  (i)  any   changes   in  law  or  the   applicable
interpretations  of the staff of the  Commission  do not permit  the  Issuers to
effect the Exchange Offer, (ii) the Exchange Offer is not consummated within 150
days of the Issue  Date,  (iii) in  certain  circumstances,  certain  holders of
unregistered Exchange Notes so request within 120 days after the consummation of
the Exchange  Offer or (iv) in the case of any holder that  participates  in the
Exchange Offer,  such holder does not receive  Exchange Notes on the date of the
exchange that may be sold without restriction under state and federal securities
laws (other than due solely to the status of such holder as an  affiliate of the
Issuers  within the meaning of the  Securities  Act) and so notifies the Issuers
within 60 days after such holder first  becomes  aware of such  restriction  and
provides the Issuers with a reasonable basis for its conclusion,  in the case of
each of clauses  (i)-(iv)  of this  sentence,  then the  Issuers  will  promptly
deliver to the holders  and the Trustee  written  notice  thereof  and, at their
cost,  (a) as  promptly  as  practicable,  file a shelf  registration  statement
covering  resales of the Notes (the  "Shelf  Registration  Statement"),  (b) use
their best  efforts to cause the Shelf  Registration  Statement  to be  declared
effective  under the  Securities  Act and (c) use their best efforts to keep the
Shelf Registration  Statement  effective until three years after their effective
date,  or such  shorter  period  ending when (i) all Notes  covered by the Shelf
Registration   Statement  have  been  sold  in  the  manner  set  forth  and  as
contemplated therein or (ii) a subsequent Shelf Registration  Statement covering
all unregistered Notes has been declared effective under the Securities Act. The
Issuers  will,  in the event of the  filing of a Shelf  Registration  Statement,
provide to each holder of the Notes copies of the prospectus  which is a part of
the  Shelf  Registration  Statement,  notify  each  such  holder  when the Shelf
Registration Statement for the Notes has become effective and take certain other
actions as are required to permit unrestricted resales of the Notes. A holder of
Notes  that  sells  such  Notes  pursuant  to the Shelf  Registration  Statement
generally  will be  required  to be named  as a  selling  securityholder  in the
related prospectus and to deliver a prospectus to purchasers, will be subject to
certain of the civil liability provisions under the Securities Act in connection
with such sales and will be bound by the provisions of the  Registration  Rights
Agreement   which  are   applicable   to  such  a  holder   (including   certain
indemnification  obligations).  In  addition,  each  holder of the Notes will be
required  to  deliver  information  to be  used in  connection  with  the  Shelf
Registration  Statement  and  to  provide  comments  on the  Shelf  Registration
Statement within the time periods set forth in the Registration Rights Agreement
in order to have its Notes included in the Shelf  Registration  Statement and to
benefit from the provisions regarding liquidated damages set forth therein.

        The summary  herein of certain  provisions  of the  Registration  Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference  to, all the  provisions  of the  Registration  Rights
Agreement, a copy of which is available without charge by writing to the Company
at 500 North Loop 1604 East,  Suite 100,  San Antonio,  Texas 78232,  Attention:
Secretary.

HOW TO TENDER

        A holder of the  Series A Notes  may  tender  the  Series A Notes by (a)
properly completing and signing the Letter of Transmittal or a facsimile thereof
(all references in this Prospectus to the Letter of Transmittal  shall be deemed
to include a facsimile  thereof)  and  delivering  the same,  together  with the
Series A Notes being  tendered (or a confirmation  of an appropriate  book-entry
transfer)  to the  Exchange  Agent  on or prior  to the  Expiration  Date or (b)
requesting a broker,  dealer, bank, trust company or other nominee to effect the
transaction for such holder prior to the Expiration Date.

        If Exchange  Notes are to be delivered to an address  other than that of
the  registered  holder  appearing on the note  register  (the "Note  Register")
maintained  by the  registrar  of the  Notes,  the  signature  on the  Letter of
Transmittal  must be guaranteed by a commercial  bank or trust company having an
office or correspondent in the United States,  or by a member firm of a national
securities exchange or the National Association of Securities Dealers, Inc. (any
of the  foregoing  is  hereinafter  referred to as an  "Eligible  Institution").
Exchange Notes will not be issued in the name of a person other than that of the
registered holder of the Series A Notes appearing on the Note Register.

        The Exchange  Agent will establish an account with respect to the Series
A Notes at DTC within two business days after the date of this  Prospectus,  and
any  financial  institution  which is a participant  in DTC may make  book-entry
delivery of the Series A Notes by causing  DTC to  transfer  such Series A Notes
into the Exchange  Agent's  account in accordance  with DTC's procedure for such
transfer.  Although  delivery  of the  Series A Notes  may be  effected  through
book-entry  transfer  into the  Exchange  Agent's  account at DTC, the Letter of
Transmittal,  with any  required  signature  guarantees  and any other  required
documents, must in any case be transmitted to and received by the Exchange Agent
on or prior to the Expiration Date at one of its addresses set forth below under
"Exchange  Agent",  or in  compliance  with the  guaranteed  delivery  procedure
described  below.  DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE  DELIVERY TO
THE EXCHANGE AGENT.  All references in this Prospectus to deposit or delivery of
Series A Notes shall be deemed to include DTC's book-entry delivery method.

        Notwithstanding  the  foregoing,  any  financial  institution  that is a
participant in the  Depository's  Book-Entry  Transfer  Facility system may make
book-entry  delivery of the Existing Notes by causing the Depositary to transfer
such Existing  Notes into the Exchange  Agent's  account in accordance  with the
Depository's  Automated  Tender  Offer  Program  ("ATOP")  procedures  for  such
book-entry  transfers.  However, the exchange for the Existing Notes so tendered
will only be made after timely  confirmation  (a "Book-Entry  Confirmation")  of
such Book-Entry  Transfer of Existing Notes into the Exchange  Agent's  account,
and timely receipt by the Exchange Agent of an Agent's  Message (as such term is
defined in the next sentence) and any other documents  required by the Letter of
Transmittal.  The term "Agent's  Message"  means a message,  transmitted  by the
Book-Entry  Transfer  Facility and received by the Exchange  Agent and forming a
part of a Book-Entry  Confirmation,  which states that the  Book-Entry  Transfer
Facility has received an express acknowledgment from a participant tendering the
Series A Notes that is the  subject of such  Book-Entry  Confirmation  that such
participant  has  received  and agrees to be bound by the terms of the Letter of
Transmittal,  and that the Issuers  may  enforce  such  agreement  against  such
participant.

        THE METHOD OF  DELIVERY  OF THE SERIES A NOTES AND ALL OTHER  DOCUMENTS,
INCLUDING  DELIVERY  THROUGH DTC, IS AT THE ELECTION AND RISK OF THE HOLDER.  IF
SENT BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT  REQUESTED,
BE USED, AND PROPER INSURANCE BE OBTAINED.

        If a holder  desires to tender  Series A Notes  pursuant to the Exchange
Offer and such  holder's  Series A Notes are not  immediately  available or time
will not permit all of the above  documents to reach the Exchange Agent prior to
the Expiration  Date, or such holder cannot complete the procedure of book-entry
transfer  on a timely  basis,  such  tender  may be  effected  if the  following
conditions are satisfied:

        (a) such tenders are made by or through an Eligible Institution;

        (b)  a  properly  completed  and  duly  executed  Notice  of  Guaranteed
Delivery,  in substantially the form provided by the Issuers, is received by the
Exchange Agent as provided below on or prior to the Expiration Date; and

        (c) the Series A Notes, in proper form for transfer (or  confirmation of
book-entry  transfer of such Series A Notes into the Exchange Agent's account at
DTC as described  above),  together with a properly  completed and duly executed
Letter  of  Transmittal  and all  other  documents  required  by the  Letter  of
Transmittal,  are  received by the  Exchange  Agent  within three New York Stock
Exchange,  Inc.  trading  days  after the date of  execution  of such  Notice of
Guaranteed Delivery.

        The  Notice  of  Guaranteed   Delivery  may  be  delivered  by  hand  or
transmitted by facsimile  transmission  or mailed to the Exchange Agent and must
include a  guarantee  by an Eligible  Institution  in the form set forth in such
Notice of Guaranteed Delivery.

        A tender  will be deemed to have been  received  as of the date when the
tendering  holder's duly signed Letter of  Transmittal  accompanied  by Series A
Notes (or a timely  confirmation  received of a book-entry  transfer of Series A
Notes  into the  Exchange  Agent's  account  at DTC) or a Notice  of  Guaranteed
Delivery  from an  Eligible  Institution  is  received  by the  Exchange  Agent.
Issuances of Exchange Notes in exchange for Series A Notes tendered  pursuant to
a Notice of  Guaranteed  Delivery by an Eligible  Institution  will be made only
against delivery of the Letter of Transmittal (and any other required documents)
and the  tendered  Series  A  Notes  (or a  timely  confirmation  received  of a
book-entry  transfer of Series A Notes into the Exchange Agent's account at DTC)
with the Exchange Agent.

        Partial  tenders of Series A Notes may be made only if (i) the principal
amount tendered is equal to $1,000 or an integral multiple thereof; and (ii) the
remaining  untendered  portion of such Series A Note is in a principal amount of
$250,000,  or any integral multiple of $1,000 in excess of such amount.  Holders
tendering less than the entire  principal  amount of any Series A Note they hold
in accordance with the foregoing  restrictions must appropriately  indicate such
fact on the Letter of Transmittal accompanying the tendered Series A Note.

        With  respect to tenders of Series A Notes,  the  Issuers  reserve  full
discretion to determine  whether the  documentation is complete and generally to
determine  all  questions  as to  tenders,  including  the date of  receipt of a
tender,  the propriety of execution of any document,  and other  questions as to
the validity,  form,  eligibility or  acceptability  of any tender.  The Issuers
reserve the right to reject any tender not in proper form or otherwise not valid
or the  acceptance  of exchange  of which may,  in the  opinion of the  Issuers'
counsel,  be  unlawful or to waive any  irregularities  or  conditions,  and the
Issuers'  interpretation  of the  terms and  conditions  of the  Exchange  Offer
(including the  instructions  on the Letter of Transmittal)  will be final.  The
Issuers  shall not be obligated to give notice of any defects or  irregularities
in  tenders  and  shall not incur any  liability  for  failure  to give any such
notice.  The Exchange  Agent may, but shall not be obligated  to, give notice of
any irregularities or defects in tenders,  and shall not incur any liability for
any failure to give any such  notice.  The Series A Notes shall not be deemed to
have  been  duly  or  validly   tendered   unless  and  until  all  defects  and
irregularities  have been  cured or waived.  All  improperly  tendered  Series A
Notes, as well as Series A Notes in excess of the principal  amount tendered for
exchange,  will be returned (unless  irregularities and defects are timely cured
or waived),  without cost to the  tendering  holder (or, in the case of Series A
Notes  delivered  by  book-entry  transfer  within DTC,  will be credited to the
account  maintained  within DTC by the  participant in DTC which  delivered such
shares), promptly after the Expiration Date.

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

        The Letter of Transmittal  contains,  among other things,  certain terms
and conditions which are summarized below and are part of the Exchange Offer.

        Each holder who  participates  in the Exchange Offer will be required to
represent  that  any  Exchange  Notes  received  by it will be  acquired  in the
ordinary  course  of its  business,  that  at the  time of  consummation  of the
Exchange Offer such holder will have no arrangement  or  understanding  with any
person to participate in the  distribution of the Exchange Notes in violation of
the  provision of the  Securities  Act, and that such holder is not an affiliate
within the meaning of the Securities Act.

        The Series A Notes  tendered in exchange  for the  Exchange  Notes (or a
timely  confirmation  of a  book-entry  transfer of such Series A Notes into the
Exchange  Agent's account at DTC) must be received by the Exchange  Agent,  with
the Letter of Transmittal  and any other required  documents,  by 5:00 p.m., New
York City time, on or prior to ___________, 199_, unless extended, or within the
time  periods  set forth  above in "-- How to  Tender"  pursuant  to a Notice of
Guaranteed Delivery from an Eligible Institution. The party tendering the Series
A Notes for exchange (the "Holder") will sell,  assign and transfer the Series A
Notes to the Exchange Agent, as agent of the Issuers, and irrevocably constitute
and appoint the Exchange  Agent as the Holder's  agent and  attorney-in-fact  to
cause the  Series A Notes to be  transferred  and  exchanged.  The  Holder  will
warrant that it has full power and authority to tender,  exchange,  sell, assign
and transfer the Series A Notes and to acquire the Exchange  Notes issuable upon
the exchange of such tendered  Series A Notes,  the Exchange  Agent, as agent of
the Issuers,  will acquire good and unencumbered  title to the tendered Series A
Notes, free and clear of all liens, restrictions,  charges and encumbrances, and
that the Series A Notes  tendered  for  exchange  are not subject to any adverse
claims when accepted by the Exchange Agent, as agent of the Issuers.  The Holder
will also covenant and agree that it will, upon request, execute and deliver any
additional documents deemed by the Issuers or the Exchange Agent to be necessary
or desirable  to complete the  exchange,  sale,  assignment  and transfer of the
Series A Notes. All authority  conferred or agreed to be conferred in the Letter
of  Transmittal by the Holder will survive the death or incapacity of the Holder
and any  obligation  of the  Holder  shall be binding  upon the heirs,  personal
representatives, successors and assigns of such Holder.

        Signature(s)  on the  Letter  of  Transmittal  will  be  required  to be
guaranteed  as set forth above in "-- How to Tender."  All  questions  as to the
validity, form, eligibility (including time of receipt) and acceptability of any
tender will be determined  by the Issuers,  in their sole  discretion,  and such
determination  will  be  final  and  binding.  Unless  waived  by  the  Issuers,
irregularities  and defects must be cured by the  Expiration  Date.  The Issuers
will pay all security  transfer  taxes,  if any,  applicable to the transfer and
exchange of the Series A Notes tendered.

WITHDRAWAL RIGHTS

        All tenders of the Series A Notes may be  withdrawn at any time prior to
acceptance  thereof  on the  Expiration  Date.  To be  effective,  a  notice  of
withdrawal  must be timely  received  by the  Exchange  Agent at the address set
forth below under "-- Exchange Agent." Any notice of withdrawal must specify the
person named in the Letter of Transmittal as having  tendered the Series A Notes
to be  withdrawn.  If the Series A Notes have been  physically  delivered to the
Exchange Agent, the tendering holder must also submit the serial number shown on
the particular  Series A Notes to be withdrawn.  If the Series A Notes have been
delivered pursuant to the book-entry  procedures set forth above under "--How to
Tender,"  any  notice of  withdrawal  must  specify  the name and  number of the
participant's  account at DTC to be credited with the withdrawn  Series A Notes.
The Exchange Agent will return the properly  withdrawn Series A Notes as soon as
practicable  following receipt of notice of withdrawal.  All questions as to the
validity,  including  time  of  receipt,  of  notices  of  withdrawals  will  be
determined by the Issuers,  and such determinations will be final and binding on
all parties.

ACCEPTANCE OF TENDERS

        Subject to the terms and conditions of the Exchange Offer, including the
reservation  of  certain  rights by the  Issuers,  the  Series A Notes  tendered
(either  physically  or through  book-entry  delivery as described in "-- How to
Tender") with a properly  executed  Letter of Transmittal and all other required
documentation, and not withdrawn, will be accepted promptly after the Expiration
Date.  Subject  to such  terms and  conditions,  Exchange  Notes to be issued in
exchange  for  properly  tendered  Series A Notes  will  either be mailed by the
Exchange  Agent or  credited  to the  holder's  account in  accordance  with the
appropriate  book-entry procedures promptly after the acceptance of the properly
tendered  Series A Notes.  Acceptance  of Series A Notes will be effected by the
delivery  of a notice  to that  effect by the  Issuers  to the  Exchange  Agent.
Subject to the applicable rules of the Commission, the Issuers, however, reserve
the  right,  prior to the  acceptance  of  tendered  Series  A  Notes,  to delay
acceptance  of  tendered  Series  A  Notes  upon  the  occurrence  of any of the
conditions  set forth  above  under the  caption  "--  Conditions."  The Issuers
confirms  that their  reservation  of the right to delay  acceptance of tendered
Series A Notes is subject to the  provisions of Rule 14e-1(c) under the 1934 Act
which requires that a tender offeror pay the consideration offered or return the
tendered  securities  promptly  after the  termination or withdrawal of a tender
offer.

        Although  the Issuers do not  currently  intend to do so, if they modify
the terms of the Exchange  Offer,  such modified  terms will be available to all
holders  of  Series A Notes,  whether  or not  their  Series A Notes  have  been
tendered prior to such modification. Any material modification will be disclosed
in accordance with the applicable rules of the Commission and, if required,  the
Exchange  Offer will be  extended to permit  holders of Series A Notes  adequate
time to consider such modification.

        The tender of Series A Notes  pursuant to any one of the  procedures set
forth in "-- How to Tender" will  constitute an agreement  between the tendering
holder  and the  Issuers  upon the terms and  subject to the  conditions  of the
Exchange Offer.

        The Issuers  will not receive any  proceeds as a result of the  Exchange
Offer.

        The net  proceeds to the Issuers from the  Offering  were  approximately

certain  expenses  incurred in connection with the  Transactions.  The following

                         PRO FORMA FINANCIAL INFORMATION

        The following  unaudited pro forma  financial  data are derived from the
historical  financial  statements  of the  Company set forth  elsewhere  in this
Prospectus and are adjusted to reflect the consummation of the Transactions.

        The  Unaudited  Pro Forma  Condensed  Balance Sheet of the Company as of
September 30, 1996 has been prepared  assuming the Transactions were consummated
on September 30, 1996,  and the Unaudited Pro Forma  Statements of Operations of
the Company  for the year ended  December  31,  1995 and the nine  months  ended
September 30, 1996 have been prepared assuming the Transactions were consummated
on January 1, 1995 and January 1, 1996,  respectively.  The historical  revenues
and expenses of CGGS, the Wyoming Properties,  Portilla and Happy and East White
Point and Stedman Island  represent  amounts recorded by or with respect to such
businesses or properties for the periods indicated.

         The historical  financial  statements of CGGS were prepared in Canadian
dollars in accordance with Canadian  generally accepted  accounting  principles.
This  information  has  been  adjusted  to  present  the  historical   financial
statements  in  accordance  with United  States  generally  accepted  accounting
principles.  The statements of operations have been translated into U.S. dollars
at the average  exchange rates of $0.7321 and $0.7273 to one Canadian dollar for
the nine months  ended  October  31, 1996 and the fiscal year ended  October 31,
1995,  respectively.  The monetary amounts on the unaudited  balance sheet as of
October 31, 1996 have been translated at the period-end exchange rate of $0.7458
to  one  Canadian  dollar.  Non-monetary  amounts  have  been  translated  at  a
historical  November 1, 1994 rate with  changes in the  amounts  since that date
translated at the average rate over the twenty-month period.

        The Company  previously  owned a 50% working  interest in Portilla and a
12% working  interest in Happy. In March 1996, the Company sold its interests in
Portilla  and  Happy  to Acco  for net  consideration  of  $15.6  million.  Acco
separately  obtained  the  release of the 50%  overriding  royalty  interest  in
Portilla  previously owned by the Pension Fund and subsequently  contributed its
interests in Portilla and Happy to the  Partnership.  The pro forma  adjustments
assume that the Issuers  acquired the Pension Fund's interest in Portilla at the
beginning of the periods indicated and that the Issuers owned Portilla and Happy
during the period from March 21, 1996 to September 30, 1996.

        The Unaudited Pro Forma Condensed Balance Sheet reflects the preliminary
allocations of the purchase prices for the Recent Acquisitions to the assets and
liabilities of the Company. The final allocation of the purchase prices, and the
resulting  effect  on DD&A  expense  in the  accompanying  unaudited  Pro  Forma
Statements of Operations, will differ from the preliminary estimates because the
final  allocation  will be based on the actual closing date purchase  prices and
the estimated fair values of the assets and liabilities.

        The unaudited  pro forma  financial  data should be read in  conjunction
with the notes thereto, the Consolidated Financial Statements of the Company and
the notes thereto and the historical financial information and the notes thereto
relating  to CGGS,  the  Wyoming  Properties  and  Portilla  and Happy  included
elsewhere in this Prospectus.

        The  unaudited  pro  forma  financial  data  are not  indicative  of the
financial  position or results of operations of the Company which would actually
have occurred if the  Transactions  had occurred at the dates presented or which
may  be  obtained  in  the  future.   In  addition,   future  results  may  vary
significantly  from the results reflected in such statements due to normal crude
oil and natural gas production declines, reductions in prices paid for crude oil
and natural gas, future acquisitions and other factors.

                            NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

Note 1. The pro forma  unaudited  Statements of Operations for the periods ended
December  31,  1995 and  September  30,  1996  reflect  the  Transactions  as if
consummated on January 1, 1995 and January 1, 1996, respectively:

a.    To  adjust  for  the  sale  of the  Nevis  Plant  prior  to  the  Issuers'
      acquisition of CGGS.

    The  reduction in G&A expense  represents  the  contractual  management  and
administrative  fee paid to the  operator  related  to the  results of the Nevis
Plant,  net of overhead  recoveries  charged to third parties for  processing of
natural gas.

    The reduction in interest  expense  relates to the repayment of a portion of
the debentures  issued by CGGS in connection  with its  acquisition of the Nevis
Plant.

b. To adjust DD&A  expense for the year ended  December  31, 1995 to reflect the
acquisition of CGGS, the Wyoming Properties, the 50% overriding royalty interest
in Portilla  previously owned by the Pension Fund and the 50% overriding royalty
interest  in East White  Point and Stedman  Island for the twelve  months  ended
December 31, 1995 and to adjust DD&A expense for the nine months ended September
30, 1996 to reflect  the  acquisitions  of CGGS,  the  Wyoming  Properties,  the
reacquisition  of Portilla  and Happy for the period March 21, 1996 to September
30, 1996, the  acquisition of the 50%  overriding  royalty  interest in Portilla
previously  owned by the Pension  Fund for the nine months ended  September  30,
1996 and the 50%  overriding  royalty  interest  in East White Point and Stedman
Island for the nine months ended  September 30, 1996.  DD&A expense of crude oil
and natural gas  properties is computed  using the units of  production  method.
Depreciation of natural gas processing facilities is computed using the straight
line method over the estimated useful life of 18 years.

c.  To adjust G&A expense of CGGS to reflect the following:

                                               Fiscal      Nine Months Ended

Note 2. The pro forma  unaudited  Condensed  Balance  Sheet as of September  30,
1996, reflects the Transactions as if they had occurred as of September 30, 1996
as follows (the  acquisition of the Wyoming  Properties  closed on September 30,
1996,  and is  reflected  in the  historical  balance  sheet of the  Company  at
September  30,  1996  the  acquisitions  of CGGS and  Portilla  and  Happy  were
consummated  on November  14, 1996 and the  acquisition  of East White Point and
Stedman Island was consummated on November 27, 1996):

a. Canadian Abraxas purchased all of the outstanding  shares of capital stock of
CGGS and  immediately  thereafter  merged CGGS with and into  Canadian  Abraxas.
Prior to the Canadian Abraxas'  acquisition of CGGS, the Nevis Plant was sold to
a third  party  and  Canadian  Abraxas,  as the  surviving  entity  of the  CGGS
acquisition,  used the net  proceeds  from the sale of the Nevis Plant to retire
the  outstanding  debentures  of CGGS.  The CGGS balance  sheet  included in the
accompanying  Unaudited Pro Forma Condensed  Balance Sheet dated as of September
30, 1996 represents the historical unaudited balance sheet of CGGS as of October
31, 1996, converted into United States generally accepted accounting  principles
and into U.S. dollars. The balances included in the "Adjustments to Reflect Sale
of Nevis" column on the accompanying Unaudited Pro Forma Condensed Balance Sheet
represent  the sale of the  Nevis  Plant and  related  accounts  receivable  and
payable at a sales price of approximately  CDN$116.1  million,  net of estimated
selling  costs and  related  closing  adjustments,  or  approximately  U.S.$87.0
million, and the removal of the historical net book value of the Nevis Plant and
the working capital and other liabilities  associated with the operations of the
Nevis Plant as of October 31, 1996.  Retained earnings represent the approximate
gain from the sale of the Nevis Plant.

b. The  acquisition  of CGGS was accounted for as a purchase in accordance  with
Accounting Principles Board Opinion No. 16 "Business Combinations." The purchase
price was allocated to the crude oil and natural gas properties, the natural gas
processing  plants and other assets based upon estimated fair values. A deferred
income tax liability  has been  established  representing  the tax effect of the
difference  in the fair value of the assets  acquired and their  historical  tax
basis and has been  allocated as  additional  basis of the crude oil and natural
gas properties, the natural gas processing plants and other assets.

        In connection  with the Acco Sale,  Acco entered into a commodity  price
hedge with Christiania which was assumed by the Company and BTCo and ING Capital
in connection with the consummation of the Transactions. Under the terms of this
commodity  price  hedge,  the Company is required to receive or make  payment to
BTCo and ING Capital based on a differential  between a fixed and variable price
for crude oil and natural gas through the last  business day of November 2001 on
volumes  ranging from 8,160 barrels of crude oil to 20,000  barrels of crude oil
per month and 14,850  MMBTU of natural  gas to 87,406  MMBTU of natural  gas per
month.  Under this  agreement,  the Company  receives  fixed prices ranging from
$17.20  per barrel of crude oil to $18.55 per barrel of crude oil and $1.793 per
MMBTU of natural gas to $1.925 per MMBTU of natural gas and makes payments based
on the price for west Texas  intermediate light sweet crude oil on the NYMEX for
crude oil and the Inside FERC,  Tennessee  Gas Pipeline Co: Texas (Zone 0) price
for natural gas.  Currently there is a net unrealized loss of approximately $1.8
million under the commodity price hedge.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following is a discussion  of the  Company's'  financial  condition,
results of operations,  liquidity and capital resources.  This discussion should
be read in conjunction with the Consolidated Financial Statements of the Issuers
and the notes thereto included elsewhere in this Prospectus.

RESULTS OF OPERATIONS

        The  Company's  revenue,  profitability  and  future  rate of growth are
substantially dependent upon prevailing prices for crude oil and natural gas and
the volumes of crude oil,  natural  gas and NGLs  produced  by the  Company.  In
addition,  the  Company's  proved  reserves  will decline as crude oil, NGLs and
natural gas are produced unless the Company is successful in acquiring producing
properties or conducts successful exploration and development activities.

         Selected  Operating  Data.  The  following  table  sets  forth  certain
operating data of the Issuers for the periods presented:

COMPARISON  OF NINE  MONTHS  ENDED  SEPTEMBER  30,  1996 TO  NINE  MONTHS  ENDED
SEPTEMBER 30, 1995

        OPERATING  REVENUE.  Operating  revenue from crude oil, NGLs and natural
gas sales increased by 20.3%, from $9.8 million to $11.8 million,  from the nine
months ended  September  30, 1995 to the nine months ended  September  30, 1996,
primarily due to an increase in crude oil, NGLs and natural gas sales prices and
increased  production volumes from the Company's  properties other than Portilla
and  Happy  in 1996 as  compared  to 1995  which  somewhat  offset  the  loss in
production  volumes from the sale of Portilla and Happy.  Operating revenue from
Portilla  and Happy  decreased  from $3.3  million to $1.2 million from the nine
months ended September 30, 1995 to the nine months ended September 30, 1996. The
Company's  average  sales  prices for its crude oil,  NGLs and  natural gas were
$17.24 per Bbl,  $10.94 per Bbl and $1.41 per Mcf,  respectively,  for the first
nine months of 1995 as compared to $19.94 per Bbl,  $12.73 per Bbl and $1.95 per
Mcf,  respectively,  for the first nine months of 1996. Crude oil and NGLs sales
volumes decreased by 4.6%, from 390.0 MBbls to 372.1 MBbls, from the nine months
ended September 30, 1995 to the nine months ended September 30, 1996 and natural
gas sales volumes decreased by 0.7%, from 2,645.1 MMcf to 2,625.4 MMcf, from the
nine months ended September 30, 1995 to the nine months ended September 30, 1996
as a result of the sale of Portilla and Happy.  Portilla  and Happy  contributed
161.8  MBbls of crude oil and NGLs  (41.5% of  Company  total) and 376.0 MMcf of
natural  gas (14.2% of Company  total)  during the first nine  months of 1995 as
compared to 54.2 MBbls of crude oil and NGLs (14.6% of Company  total) and 117.5
MMcf of natural gas (4.5% of Company total) for the first nine months of 1996.

        LEASE  OPERATING  EXPENSES.  LOE increased by 3.6%, from $3.2 million to
$3.3  million,  from the first nine  months of 1995 to the first nine  months of
1996, primarily due to the increased percentage of the Company's production base
attributable  to west Texas crude oil production than that from Texas Gulf Coast
properties,  which generally have lower LOE than the west Texas  properties.  Of
the LOE incurred during the first nine months of 1995, $445,000, or 14.0% of the
Company's  total LOE, was  attributable  to Portilla  and Happy,  as compared to
$233,000,  or 7.1% of the Company's  total LOE,  during the first nine months of
1996. The Company's LOE on a per BOE basis for the first nine months of 1995 was
$3.83 per BOE as compared to $4.07 per BOE for the first nine months of 1996.

        G&A  EXPENSES.  G&A expenses  increased by 62.7%,  from $769,000 to $1.2
million,  from the first nine  months of 1995 to the first nine  months of 1996,
primarily as a result of hiring  additional staff to manage the Issuers' assets,
including the establishment of a Canadian  administrative  office. The Company's
G&A expenses on a per BOE basis for the first nine months of 1995 were $0.93 per
BOE as compared to $1.54 per BOE for the first nine months of 1996.

        DD&A  EXPENSES.  DD&A  increased  by 17.1%,  from $3.5  million  to $4.2
million,  from the first nine  months of 1995 to the first  nine  months of 1996
primarily due to the increase in sales volumes of crude oil and natural gas. The
Company's  DD&A  expenses  on a per BOE basis for the first nine  months of 1995
were $4.27 per BOE as  compared  to $5.27 per BOE for the first  nine  months of
1996.

        INTEREST EXPENSE AND PREFERRED DIVIDENDS. Interest expense and preferred
dividends  decreased  24.2%,  from $3.2 million to $2.4 million,  from the first
nine  months  of 1995 to the  first  nine  months  of  1996.  The  decrease  was
attributable  to the sale of Portilla  and Happy,  part of the proceeds of which
were used to reduce the  indebtedness  outstanding  under the First Union Credit
Facility by $12.0 million to $29.5 million.

COMPARISON OF YEAR ENDED DECEMBER 31, 1994 TO YEAR ENDED DECEMBER 31, 1995

        OPERATING  REVENUE.  Operating  revenue from crude oil, NGLs and natural
gas sales increased by 22.9%, from $11.1 million to $13.7 million, from the year
ended December 31, 1994 to the year ended  December 31, 1995.  This increase was
primarily  attributable  to an increase  in crude oil and NGLs sales  volumes of
16.2%,  from 468.9  MBbls to 544.8  MBbls,  and an increase in natural gas sales
volumes of 48.5%,  from  2,392.9  MMcf to 3,552.7  MMcf.  The  increase in sales
volumes were primarily  attributable to the acquisition of 80% of the overriding
royalty interest previously granted to a lender (the "ORRI") and the acquisition
of certain properties located in west Texas (the "West Texas Properties") by the
Company in June 1994 and July 1994,  respectively.  The Company's  average sales
prices for its crude oil,  NGLs and natural gas were $15.47 per Bbl,  $10.54 per
Bbl and $1.85 per Mcf,  respectively,  for the year ended  December  31, 1994 as
compared to $17.16 per Bbl, $10.83 per Bbl and $1.47 per Mcf, respectively,  for
the year ended  December 31, 1995. A general  weakening of natural gas prices at
the wellhead  during the first nine months of 1995  resulted in a lower  average
natural gas sales price  received by the Company  during the year ended December
31, 1995 as compared to the year ended  December  31,  1994.  This  decrease was
partially  offset by an  increase  in average  crude oil prices  received by the
Company  during the year ended  December  31, 1995 as compared to the year ended
December 31, 1994.

        LEASE OPERATING  EXPENSES.  LOE increased by 17.3%, from $3.7 million to
$4.3 million,  from the year ended  December 31, 1994 to the year ended December
31, 1995, primarily due to the Company's owning a greater number of wells during
the year ended  December 31, 1995 than it did during the year ended December 31,
1994.  The Company's LOE on a per BOE basis for the year ended December 31, 1994
was $4.26 per BOE as compared to $3.81 per BOE for the year ended  December  31,
1995.

        G&A  EXPENSES.  G&A expenses  increased by 28.6%,  from $810,000 to $1.0
million,  from the year ended  December 31, 1994 to the year ended  December 31,
1995 as a result of hiring additional staff to manage and develop the West Texas
Properties.  The  Company's  G&A  expenses on a per BOE basis for the year ended
December  31,  1994 were $0.93 per BOE as compared to $0.92 per BOE for the year
ended December 31, 1995.

        DD&A  EXPENSES.  DD&A  increased  by 43.4%,  from $3.8  million  to $5.4
million,  from the year ended  December 31, 1994 to the year ended  December 31,
1995  primarily  as a result of the  increase in sales  volumes of crude oil and
natural gas. The  Company's  DD&A expenses on a per BOE basis for the year ended
December  31,  1994 were $4.37 per BOE as compared to $4.78 per BOE for the year
ended December 31, 1995.

        INTEREST EXPENSE AND PREFERRED DIVIDENDS. Interest expense and preferred
dividends increased 68.3%, from $2.5 million to $4.3 million from the year ended
December 31, 1994 to the year ended December 31, 1995,  primarily as a result of
the Company's  borrowing  $28.0 million under the First Union Credit Facility to
acquire the West Texas Properties in July 1994.

COMPARISON OF YEAR ENDED DECEMBER 31, 1993 TO YEAR ENDED DECEMBER 31, 1994

        OPERATING  REVENUE.  Operating  revenue from crude oil, NGLs and natural
gas sales increased by 52.8%, from $7.3 million to $11.1 million,  from the year
ended December 31, 1993 to the year ended  December 31, 1994.  This increase was
primarily  attributable  to an increase  in crude oil and NGLs sales  volumes of
53.8%,  from 304.8  MBbls to 468.9  MBbls,  and an increase in natural gas sales
volumes of  142.8%,  from 985.4 MMcf to  2,392.9  MMcf.  The  increase  in sales
volumes was primarily  attributable  to the acquisition of the ORRI and the West
Texas  Properties by the Company in June 1994 and July 1994,  respectively,  the
further development of the Sinton Properties, which were acquired in April 1993,
and the Company's ongoing  development  drilling program.  The Company's average
sales prices for its crude oil, NGLs and natural gas were $15.54 per Bbl, $14.75
per Bbl and $2.60 per Mcf, respectively, for the year ended December 31, 1993 as
compared to $15.47 per Bbl, $10.54 per Bbl and $1.85 per Mcf, respectively,  for
the year ended  December 31, 1994. A general  weakening of natural gas prices at
the wellhead during the year ended December 31, 1994 resulted in a lower average
natural  gas sales  price  received  by the  Company as  compared to the average
natural gas sales price  received by the Issuers  during the year ended December
31, 1993.

        LEASE OPERATING  EXPENSES.  LOE increased by 27.5%, from $2.9 million to
$3.7 million,  from the year ended  December 31, 1993 to the year ended December
31, 1994, primarily due to the Company's owning a greater number of wells during
the year ended  December 31, 1994 than it did during the year ended December 31,
1993.  The Company's LOE on a per BOE basis for the year ended December 31, 1993
was $6.17 per BOE as compared to $4.26 per BOE for the year ended  December  31,
1994.

        G&A  EXPENSES.  G&A  expenses  increased  by  59.0%,  from  $510,000  to
$810,000,  from the year ended  December 31, 1993 to the year ended December 31,
1994 as a result of an increase in staff.  The  Company's  G&A expenses on a per
BOE basis for the year ended December 31, 1993 were $1.09 per BOE as compared to
$0.93 per BOE for the year ended December 31, 1994.

        DD&A  EXPENSES.  DD&A  increased  by 59.7%,  from $2.4  million  to $3.8
million,  from the year ended  December 31, 1993 to the year ended  December 31,
1994  primarily  as a result of the  increase in sales  volumes of crude oil and
natural gas. The  Company's  DD&A expenses on a per BOE basis for the year ended
December  31,  1993 were $5.06 per BOE as compared to $4.37 per BOE for the year
ended December 31, 1994.

        INTEREST EXPENSE AND PREFERRED DIVIDENDS. Interest expense and preferred
dividends  decreased by 6.4%,  from $2.7 million to $2.5 million,  from the year
ended  December 31, 1993 to the year ended  December  31,  1994,  primarily as a
result of the Company's restructuring its long-term debt in June 1994.

</TABLE>

        Acquisitions of crude oil and natural gas producing properties beginning
in 1993 and continuing  through the nine months ended September 30, 1996 account
for the majority of the capital  expenditures  made by the Issuers since January
1, 1993. These expenditures were funded through internally  generated cash flow,
borrowings from the Issuers' lenders and the issuance of shares of the Company's
Common and Preferred Stock.

        After  consummation  of the Offering and application of the net proceeds
therefrom,  the Company  increased its total  outstanding  debt to approximately
$215.1  million from $85.0  million at  September  30,  1996.  In  addition,  on
November 14, 1996, the Company entered into the New Credit Facility concurrently
with the  consummation of the Offering.  The New Credit Facility  provides for a
revolving line of credit with an initial availability of $20.0 million,  subject
to certain customary conditions including a borrowing base condition.

        Commitments  available  under the New  Credit  Facility  are  subject to
Borrowing Base redeterminations to be performed semi-annually and, at the option
of each of the  Company  and the  Lenders,  one  additional  time per year.  Any
outstanding  principal  balance in excess of the Borrowing  Base will be due and
payable in three equal monthly payments after a Borrowing Base  redetermination.
The Borrowing Base will be determined in the Agent's sole discretion, subject to
the approval of the Lenders, based on the value of the Company's reserves as set
forth in the reserve report of the Company's  independent  petroleum  engineers,
with consideration given to other assets and liabilities.

        The New Credit Facility has an initial revolving term of two years and a
reducing period of three years from the end of the initial two-year period.  The
commitment  under the New Credit  Facility will be reduced  during such reducing
period by eleven equal  quarterly  reductions.  Quarterly  reductions will equal
8.2% per quarter with the  remainder due at the end of the  three-year  reducing
period.

        The applicable  interest rate charged on the outstanding  balance of the
New Credit  Facility is based on a facility usage grid. If the borrowings  under
the New Credit  Facility  represent an amount less than or equal to 33.3% of the
available  Borrowing  Base,  then the  applicable  interest  rate charged on the
outstanding balance will be either (a) an adjusted rate of the London Inter-Bank
Offered Rate  ("LIBOR")  plus 1.25% or (b) the prime rate of the Agent (which is
based on the Agent's  published prime rate) plus 0.50%. If the borrowings  under
the New Credit  Facility  represent an amount greater than or equal to 33.3% but
less than 66.7% of the available  Borrowing Base,  then the applicable  interest
rate on the outstanding principal will be either (a) LIBOR plus 1.75% or (b) the
prime  rate of the Agent  plus  0.50%.  If the  borrowings  under the New Credit
Facility  represent an amount  greater  than or equal to 66.7% of the  available
Borrowing Base, then the applicable  interest rate on the outstanding  principal
will be either  (a) LIBOR  plus  2.00% or (b) the prime  rate of the Agent  plus
0.50%. LIBOR elections can be made for periods of one, three or six months.

        The New Credit Facility contains a number of covenants that, among other
things, restrict the ability of the Company to (i) incur certain indebtedness or
guarantee obligations, (ii) prepay other indebtedness including the Notes, (iii)
make investments, loans or advances, (iv) create certain liens, (v) make certain
payments, dividends and distributions, (vi) merge with or sell assets to another
person or  liquidate,  (vii)  sell or  discount  receivables,  (viii)  engage in
certain intercompany transactions and transactions with affiliates,  (ix) change
its business, (x) experience a change of control and (xi) make amendments to its
charter,  by-laws and other debt instruments.  In addition, under the New Credit
Facility,  the Company is required to comply with specified financial ratios and
tests,  including  minimum debt service coverage ratios,  maximum funded debt to
EBITDA tests, minimum net worth tests and minimum working capital tests.

        The New Credit Facility contains customary events of default,  including
nonpayment of principal, interest or fees, violation of covenants, inaccuracy of
representations  or warranties in any material respect,  cross default and cross
acceleration to certain other indebtedness,  bankruptcy,  material judgments and
liabilities and change of control.

        At September 30, 1996,  the Company had current  assets of $14.2 million
and current  liabilities of $6.6 million,  resulting in working  capital of $7.6
million.  This compares to working  capital of $2.6 million at December 31, 1995
and a deficiency of $2.5 million at September 30, 1995. The material  components
of the  Company's  current  liabilities  at  September  30, 1996  include  trade
accounts payable of $4.7 million and revenue due third parties of $1.4 million.

        The  Company's  current  budget  for  capital  expenditures,  other than
acquisition  expenditures,  for the last quarter of 1996 is $6.5  million.  Such
expenditures will be made primarily for the development of existing  properties.
Additional  capital  expenditures  may be made  for  acquisitions  of  producing
properties as such opportunities arise. The Company does not have an acquisition
budget since the timing and size of acquisitions are difficult to forecast.  The
Company has no material  long-term capital  commitments and is consequently able
to adjust the level of its expenditures as circumstances dictate.  Additionally,
the level of capital  expenditures  will vary during future periods depending on
market conditions and other related economic factors.

        In August  1995,  the Company  entered into a rate swap  agreement  with
First Union relating to $25.0 million of principal amount  outstanding under the
First Union Credit Facility.  This agreement was assumed by BTCo and ING Capital
in  connection  with the  consummation  of the Bridge  Facility  and  remains in
effect.  Under the  agreement,  the Company pays a fixed rate of 6.15% while the
lenders  under the New Credit  Facility  will pay a  floating  rate equal to the
USD-LIBOR-BBA  rate for one month  maturities,  quoted on the  eighteenth day of
each  month,  to  the  Company.  Settlements  are  due  monthly.  The  agreement
terminates  in August 1997 and may be  extended  for an  additional  year by the
Lenders.

        In connection  with the Acco Sale,  Acco entered into a commodity  price
hedge with Christiania which was assumed by the Company and BTCo and ING Capital
in connection with the consummation of the Transactions. Under the terms of this
commodity  price  hedge,  the Company is required to receive or make  payment to
BTCo and ING Capital based on a differential  between a fixed and variable price
for crude oil and natural gas through the last  business day of November 2001 on
volumes  ranging from 8,160 barrels of crude oil to 20,000  barrels of crude oil
per month and 14,850  MMBTU of natural  gas to 87,406  MMBTU of natural  gas per
month.  Under this  agreement,  the Company  receives  fixed prices ranging from
$17.20  per barrel of crude oil to $18.55 per barrel of crude oil and $1.793 per
MMBTU of natural gas to $1.925 per MMBTU of natural  gas and will make  payments
based on the price for west  Texas  intermediate  light  sweet  crude oil on the
NYMEX for crude oil and the Inside FERC,  Tennessee Gas Pipeline Co: Texas (Zone
0) price for natural gas.

        Operating  activities  during the nine months ended  September  30, 1996
provided  $4.8  million of cash to the Company  compared to $1.4  million in the
same period in 1995. Net income plus non-cash  expense items during 1996 and net
changes in operating  assets and liabilities  accounted for most of these funds.
Investing activities required $41.1 million during the first nine months of 1996
primarily from the acquisition of the Wyoming Properties.  This compares to cash
requirements  of $6.5 million  during the same period of 1995  primarily for the
development  of crude  oil and  natural  gas  properties.  Financing  activities
provided  $41.9  million for the first nine months of 1996 compared to providing
$5.3 million for the same period of 1995.

        For the year ended December 31, 1995, operating activities provided $4.4
million of cash.  Investing  activities required $10.0 million primarily for the
development  of  existing   properties.   Total  cash  provided  from  financing
activities  for 1995 was $9.8  million  as the  result of the sale of  1,330,000
shares of Common Stock and  contingent  value rights during  November 1995 which
resulted in net proceeds of $10.1 million.

        During  1994,  operating  activities  provided  $4.3  million  of  cash.
Investing  activities  during 1994 utilized  $35.9 million of cash primarily for
the acquisition of the ORRI and the West Texas  Properties for $29.0 million and
the development of producing  properties of $7.2 million.  The Company  borrowed
$40.9 million during 1994,  repaid $12.7 million of long-term  debt, sold Common
Stock for  proceeds of $1.5  million and paid  financing  fees and  dividends on
preferred stock resulting in a net  contribution of $29.2 million from financing
activities.

        For the year ended  December 31,  1993,  operating  activities  produced
$665,000 of cash.  Investment  activities  during 1993 utilized $25.2 million of
cash  primarily for the  acquisition  of the Sinton  Properties in the amount of
$19.9 million and the development of existing producing  properties at a cost of
$5.2 million  being offset by the sale of equipment  inventory and various crude
oil and natural gas properties for $768,000.  The Company borrowed $20.6 million
during 1993 and repaid $17.2 million of long-term debt and sold 2,250,000 shares
of  Common  Stock  for  net  proceeds  of  $23.1  million  resulting  in  a  net
contribution of $26.4 million from financing activities.

        As a result of the  acquisition  of certain  partnership  interests  and
crude oil and natural gas properties in 1990 and 1991, an ownership change under
Section 382 occurred in December 1991. Accordingly,  it is expected that the use
of net operating  loss carry  forwards  generated  prior to December 31, 1991 of
$6.9 million will be limited to  approximately  $235,000 per year.  During 1992,
the Company acquired 100% of the capital stock of an unrelated corporation.  The
use of net  operating  loss carry  forwards  of $3.6  million  of the  unrelated
corporation are limited to  approximately  $115,000 per year. As a result of the
issuance of  additional  shares of Common  Stock for  acquisitions  and to raise
capital, an additional  ownership change occurred in October 1993.  Accordingly,
it is expected  that the use of the $13.4  million of net  operating  loss carry
forwards  generated  through October 1993 will be limited to approximately  $1.0
million per year,  subject to the limitations  described above, and $7.2 million
in the  aggregate.  Future changes in ownership may further limit the use of the
Company's  net  operating  loss carry  forwards.  In  addition  to  Section  382
limitations,  uncertainties  exist as to the future utilization of the operating
loss carry  forwards  under the criteria set forth under FASB Statement No. 109.
Therefore, the Company has established a valuation allowance of $5.7 million and
$5.5   million  for   deferred  tax  assets  at  December  31,  1995  and  1994,
respectively.

        Based upon the current level of  operations,  the Company  believes that
the  proceeds  from the initial  offering of the Series A Notes,  cash flow from
operations and the New Credit  Facility will be adequate to meet its anticipated
requirements for working capital,  capital  expenditures and scheduled  interest
payments for the foreseeable  future. A depressed price for natural gas or crude
oil  would  have a  material  adverse  effect  on the  Company's  cash flow from
operations  and  anticipated  levels of  working  capital,  and could  force the
Issuers to revise its planned capital expenditures.

NEW ACCOUNTING STANDARDS

        In October 1995, the FASB issued SFAS 123,  "Accounting  for Stock-Based
Compensation." SFAS 123, effective for fiscal years beginning after December 31,
1995, defines a fair value-based method of accounting and establishes  financial
accounting and reporting standards for stock-based employee  compensation plans.
Under the fair value-based  method,  compensation  cost is measured at the grant
date  based  upon the  value of the  award and is  recognized  over the  service
period.  SFAS 123 allows for the  election to  continue  to measure  stock-based
compensation  cost using the  intrinsic  value method of  Accounting  Principles
Board Opinion No. 25 "Accounting for Stock Issued to Employees"  ("APB 25"). The
election  of this  option  requires  a pro forma  disclosure  of net  income and
earnings per share as if the fair value-based  method of accounting,  as defined
by SFAS 123, had been  applied.  Currently,  the Company  expects to continue to
follow APB 25 and will adopt the required  disclosures for financial  statements
beginning in 1996.

                                    BUSINESS

GENERAL

        The Company is an independent  energy company  engaged  primarily in the
acquisition,  exploration,  development  and production of crude oil and natural
gas.  Since January 1, 1991,  the Company's  principal  means of growth has been
through the acquisition and subsequent development and exploitation of producing
properties and related assets.  The Company  utilizes a disciplined  acquisition
strategy,  focusing  its efforts on  producing  properties  and  related  assets
possessing  the  following  characteristics:   a  concentration  of  operations;
significant,  quantifiable  development  potential;  historically  low operating
expenses; and the potential to reduce G&A expenses per BOE. The Company seeks to
complement   its   acquisition   and   development   activities  by  selectively
participating in exploration projects with experienced industry partners.  After
giving  effect to the Recent  Acquisitions,  the  Company's  principal  areas of
operation are Texas,  western Canada and southwestern  Wyoming. The Company owns
interests in 225,290 gross acres  (126,845 net acres) and 507 gross wells (325.8
net wells),  352 of which are operated by the Company,  and varying interests in
13 natural  gas  processing  plants or  compression  facilities.  On a pro forma
basis,  at June 30, 1996,  the Company  would have had total proved  reserves of
45,647  MBOE  (64.9%  natural  gas),  of which  81.7%  would  have  been  proved
developed.  On a pro forma basis,  for the nine months ended September 30, 1996,
the Company's EBITDA would have been $28.4 million.

        The Company's  acquisition,  development,  exploitation  and exploration
activities  have  substantially  increased  the Company's  proved  reserve base,
average daily  production  and natural gas  processing  plant  throughput  while
decreasing its total  operating and G&A expenses per BOE. After  consummation of
the Recent Acquisitions,  the Company has completed 16 acquisitions of producing
properties totaling 46,009 MBOE of proved reserves at an average net acquisition
cost of $3.83 per BOE since  January  1,  1991.  From  January  1,  1991,  on an
historical  basis,  to June 30, 1996, on a pro forma basis,  the Company's total
proved  reserves would have increased from 889 MBOE to 45,647 MBOE and aggregate
PV-10 would have increased from $11.9 million to $218.3 million. From January 1,
1991, on an historical  basis, to the nine months ended September 30, 1996, on a
pro forma basis,  average net daily  production  would have increased from 0.141
MBOE per day to 14.1 MBOE per day. On a pro forma basis,  the Company would have
had net natural gas  processing  capacity of 128.1 MMcf per day as of  September
30, 1996. In addition, on a pro forma basis, for the nine months ended September
30, 1996,  average net daily natural gas processing  plant throughput would have
been 87.4 MMcf per day, of which 27.3 MMcf would have been  processed  for third
parties,  and net operating revenue from processing natural gas of third parties
at the Canadian Abraxas Plants would have been $1.9 million. From the year ended
December 31, 1991, on an historical  basis,  to the nine months ended  September
30, 1996, on a pro forma basis, the Company's direct operating  expenses per BOE
would have  decreased  from $6.30 per BOE to $2.81 per BOE and G&A  expenses per
BOE would have decreased from $5.39 per BOE to $0.66 per BOE. As a result of the
Company's successful acquisition strategy and its ability to decrease its direct
operating and G&A expenses per BOE, the  Company's  EBITDA  (excluding  interest
income) has increased  from $6.66 per BOE, for the year ended December 31, 1991,
to, on a pro forma basis, $7.24 per BOE, for the nine months ended September 30,
1996.

        The Company was founded in 1977 by Robert  L.G.  Watson,  the  Company's
Chairman of the Board,  President and Chief Executive Officer.  Canadian Abraxas
was formed by the  Company  in 1996 to acquire  CGGS.  The  Company's  principal
offices are located at 500 North Loop 1604 East,  Suite 100, San Antonio,  Texas
78232 and its telephone number is (210) 490-4788.  Canadian  Abraxas'  principal
offices are located at 630 - 6th Avenue,  S.W., Suite 303, Calgary,  Alberta and
its  telephone  number is (403)  262-1949.  At June 30, 1996,  pro forma for the
Recent Acquisitions,  the Company would have had total proved reserves of 45,647
MBOE (64.9%  natural gas) with an aggregate  PV-10 of $218.3  million,  71.7% of
which would have been  attributable to proved developed  reserves.  In addition,
the  Company  owns  varying  interests  in 13 natural gas  processing  plants or
compression facilities and 197 miles of natural gas gathering systems.

BUSINESS STRATEGY

        The  Company's   primary  business   objectives  are  to:  increase  its
recoverable reserves, production and cash flow from operations through strategic
acquisitions;  exploit and develop its producing  properties;  maintain low cost
operations;  and pursue a focused  exploration  strategy.  The Company  seeks to
achieve its business objectives through the use of the following strategies:

         Disciplined  Acquisition  Strategy.  The Company utilizes a disciplined
acquisition  strategy,  focusing its acquisition efforts on producing properties
and related assets possessing the following characteristics:  a concentration of
operations;  significant,  quantifiable development potential;  historically low
operating  expenses;  and the  potential  to reduce G&A  expenses  per BOE.  The

</TABLE>

In connection  with the acquisition of the Sinton  Properties,  the Company also
acquired  interests  in two  natural  gas  processing  plants,  one of which was
subsequently  sold in the Acco Sale. See "--Recent  Acquisitions -- Portilla and
Happy." Since being  acquired by the Company,  the average net daily natural gas
processing  throughput  of these plants has  increased by an average of 7.3% per
year,  revenue  has  increased  by an  average  of 24.5% per year and  operating
expenses as a percentage  of revenue  have  decreased by an average of 13.7% per
year.

         EXPLOITATION   OF  EXISTING   PROPERTIES.   The  Company   allocates  a
significant amount of its non-acquisition  capital budget to the exploitation of
its  producing  properties.  As  of  June  30,  1996,  on  a  pro  forma  basis,
approximately  18.3% (8,373 MBOE) of the Company's  total proved  reserves would
have  been  classified  as  proved  undeveloped.  Management  believes  that the
proximity of these undeveloped reserves to existing production makes development
of these  properties  less risky and more  cost-effective  than  other  drilling
opportunities available to the Company. The Company has identified 272 potential
exploitation  opportunities on the Company's existing properties including those
acquired in the Recent  Acquisitions.  The Company  drilled 29 wells  during the
first nine months of 1996 (including seven in western Canada) at a total cost of
$7.9 million  with a success rate of 93% . In addition,  the Company has drilled
or  plans  to  drill a total  of 37 wells  and has  performed  42  workovers  or
recompletions  during  1996 at an  estimated  cost of $2.8  million and plans to
drill 64 wells and  perform 35  workovers  or  recompletions  during  1997 at an
estimated cost of $22.2 million.

         LOW COST  OPERATIONS.  The Company  seeks to maintain low operating and
G&A  expenses per BOE by operating a majority of its  producing  properties  and
related assets and by using contract personnel to assist with the development or
evaluation  of  producing  properties  and related  assets.  As a result of this
strategy, the Company's EBITDA Margin has consistently improved since 1991, even
in years with depressed  commodity prices. From the year ended December 31, 1991
to,  on a pro forma  basis,  the nine  months  ended  September  30,  1996,  the
Company's  direct operating and G&A expenses per BOE have decreased by 55.4% and
87.8%, respectively, resulting in an improvement in EBITDA Margin as illustrated
below:

         FOCUSED  EXPLORATION  ACTIVITY.  The Company allocates a portion of its
capital  budget to the  drilling of  exploratory  wells which have high  reserve
potential.  The Company  believes that by devoting a relatively  small amount of
capital to high impact,  high risk projects while  reserving the majority of its
available capital for development projects, it can reduce its risk profile while
still  benefiting  from the potential for  significant  reserve  additions.  See
"Business -- Primary Operating Areas --Exploration Opportunities."

                               RECENT ACQUISITIONS

        The Company has recently acquired CGGS, the Wyoming Properties, Portilla
and Happy,  East White Point and Stedman Island for an aggregate  purchase price
of  approximately  $176.2  million  (the  "Recent  Acquisitions").  The  Company
believes that each of the Recent  Acquisitions  is consistent with the Company's
acquisition strategy.

CGGS

        In November  1996,  Canadian  Abraxas  acquired 100% of the  outstanding
capital stock of CGGS,  after the  consummation  of the sale of the Nevis Plant,
for  CDN$126.4   million,   or  approximately   U.S.$94.8   million,   including
approximately $8.3 million for CGGS' working capital.

        Canadian Abraxas owns producing  properties in western Canada consisting
primarily of natural gas reserves and interests  ranging from 10% to 100% in 197
miles of natural gas gathering  systems and 11 natural gas processing  plants or
compression  facilities,  four of which are  operated by Canadian  Abraxas.  The
Canadian  Abraxas  Properties  consist of 154,968 gross acres (86,327 net acres)
and 120 gross  wells  (68.8 net  wells),  48 of which are  operated  by Canadian
Abraxas.  As of September 1, 1996,  the Canadian  Abraxas  Properties  had total
proved  reserves of 10,821 MBOE (91.8%  natural gas) with an aggregate  PV-10 of
$46.4 million, 82.4% of which was attributable to proved developed reserves. The
Canadian  Abraxas  Plants had aggregate net natural gas  processing  capacity of
98.5 MMcf per day at September 1, 1996. For the nine months ended  September 30,
1996, the Canadian Abraxas Plants processed an average of 182.8 gross MMcf (65.7
net  MMcf)  of  natural  gas per day,  of which  19.6%  (39.7%  net) was  custom
processed for third parties.  For the nine months ended  September 30, 1996, the
Canadian  Abraxas   Properties  and  the  Canadian  Abraxas  Plants  would  have
contributed $10.3 million of EBITDA to the Company on a pro forma basis.

        The  Company  believes  that  the  Canadian   Abraxas   Properties  have
significant,  quantifiable  development  potential which can be realized through
exploitation  and development.  The Company believes that processing  volumes at
the Canadian Abraxas Plants can be increased due to unutilized gross natural gas
processing  throughput  capacity at the plants of approximately  69.5 MMcf (32.4
net MMcf) of natural  gas per day.  The Company  intends to utilize  this excess
capacity by seeking to process additional natural gas volumes from third parties
and from increased production from the Canadian Abraxas Properties. In addition,
the Company believes that expected  increasesin the demand for natural gas from,
Alberta,  Canada will help to reduce the existence of basis differentials in the
pricing of natural gas  produced in this area.  The  Company  believes  that its
ownership of the Canadian  Abraxas  Properties  and the Canadian  Abraxas Plants
will afford it a competitive  advantage  relative to other area operators due to
the  Company's  preferential  access to the natural gas  processing  capacity at
these facilities.

        Immediately after the acquisition of CGGS, the Company  amalgamated CGGS
with Canadian  Abraxas,  and Canadian  Abraxas,  being the name of the surviving
entity,  used the net  proceeds  from the sale of the Nevis  Plant to retire the
outstanding debentures of CGGS. In addition,  Canadian Abraxas intends to sell a
10% working interest in the Canadian Abraxas Properties and the Canadian Abraxas
Plants to Cascade,  in  connection  with the  Company's  plan to  integrate  the
operations of the Canadian  Abraxas  Properties and the Canadian  Abraxas Plants
into the existing  operations of Cascade.  The Company has identified  potential
cost savings through  anticipated  decreases in the G&A expenses of CGGS,  which
would  have  amounted  to  approximately  $380,000  for the  nine  months  ended
September 30, 1996, on a pro forma basis.  See the unaudited Pro Forma Financial
Information and the notes thereto included elsewhere in this Prospectus.

THE WYOMING PROPERTIES

        On September 30, 1996, the Company acquired the Wyoming Properties which
had total proved reserves of 9,935 MBOE (68.5% natural gas) as of June 30, 1996,
for $47.5  million in cash,  before  adjustment  for  accrual of net revenue and
interest  from April 1, 1996 to  September  30,  1996.  The  Wyoming  Properties
consist of 19,587  gross  acres  (14,091 net acres) and 25 gross wells (20.4 net
wells),  22 of which are  operated  by the  Company.  In  addition,  the Company
acquired  various  overriding  royalty  interests in four wells.  As of June 30,
1996, the aggregate PV-10 of the Wyoming Properties was $30.3 million (based, in
part,  on an  assumed  natural  gas price of $1.07 per Mcf),  97.3% of which was
attributable to proved developed  reserves.  For the nine months ended September
30, 1996, the Wyoming  Properties  would have contributed $5.4 million of EBITDA
to the Company on a pro forma basis.  As of September 30, 1996,  the Company has
recorded the  preliminary  net purchase  price of $45.9 million to its crude oil
and natural gas properties.

        Management   believes  that  the  Wyoming  Properties  have  significant
development  potential  which will enable the Company to increase  its cash flow
from operations and reserve base without significant capital  expenditures.  The
Company intends to exploit this development potential through the more efficient
use of compression and gathering  facilities,  low cost recompletions of various
behind-pipe  zones and drilling of infill  development  wells on closer spacing.
The Company has drilled two wells on the Wyoming  Properties since September 30,
1996.  Additionally,  the  Company has  identified  potential  exploitation  and
development  opportunities  which  it  believes  may have up to  15,400  MBOE of
additional  reserves.  The Wyoming Properties are  geographically  concentrated,
thereby  enabling  the  Company  to operate  the  properties  without  incurring
additional  G&A  expenses.  In  addition,  the Company  believes  that  expected
improvements in the transportation  infrastructure and an increase in the demand
for natural gas from  southwestern  Wyoming will help to reduce the existence of
basis differentials in the pricing of natural gas produced in the area.

PORTILLA AND HAPPY

        In November 1996, the Company  acquired Acco's  partnership  interest in
the  Partnership   for  $27.6  million,   including  the  repayment  of  certain
indebtedness  before  adjustment  for the  accrual of net revenue to the closing
date.  The  Company   previously   owned  the  remaining  25%  interest  in  the
Partnership.  The  Partnership  owned a 100%  working  interest in the  Portilla
Field, a 100% interest in the Portilla Plant and a 12% working interest in Happy
Field.  Portilla and Happy consist of 1,405 gross acres (1,115 net acres) and 78
gross wells (52 net wells), 61 of which are operated by the Company.  As of June
30,  1996,  Portilla  and Happy had total  proved  reserves of 4,314 MBOE (18.4%
natural  gas)  with an  aggregate  PV-10 of $30.2  million,  99.8% of which  was
attributable to proved  developed  reserves.  The Portilla Plant had natural gas
processing  capacity of  approximately  20.0 MMcf per day at September 30, 1996.
During the nine months ended September 30, 1996, the Portilla Plant processed an
average of 17.2 MMcf of natural gas per day. For the nine months ended September
30, 1996,  Portilla and Happy would have  contributed an additional $3.8 million
of EBITDA to the Company on a pro forma basis.

        The  Company  previously  owned a 50%  interest  in  Portilla  and a 12%
working  interest in Happy.  In March 1996,  the Company  sold its  interests in
Portilla  and  Happy  to Acco  for net  consideration  of  $15.6  million.  Acco
subsequently  obtained  the  release of a 50%  overriding  royalty  interest  in
Portilla  previously  owned by the Pension  Fund and Acco then  contributed  its
interests in Portilla and Happy to the Partnership in return for the Partnership
Interest. The Company continued to operate Portilla subsequent to the Acco Sale.
See "Recent Acquisitions -- Portilla and Happy."

EAST WHITE POINT AND STEDMAN ISLAND

        In November 1996, the Company obtained the release of the 50% overriding
royalty  interests in East White Point and Stedman  Island from the Pension Fund
for $9.3 million  before  adjustment for accrual of net revenue from August 1996
to  November  27,  1996.  The  Pension  Fund's  interest in East White Point and
Stedman  Island  consisted  of 3,723 gross acres  (1,256 net acres) and 25 gross
wells (6.5 net wells),  15 of which are operated by the Company.  As of June 30,
1996,  East White Point and Stedman  Island had total  proved  reserves of 5,304
MBOE (62.3%  natural gas) with an  aggregate  PV-10 of $29.4  million,  71.7% of
which was  attributable  to proved  developed  reserves.  The East  White  Point
natural  gas  processing  plant,  a modern  cyrogenic  plant  with  capacity  of
approximately 25.0 MMcf of natural gas per day, extracted approximately 679 Bbls
of NGLs per day for the nine months ended September 30, 1996.

PRIMARY OPERATING AREAS

TEXAS

        ABRAXAS CHERRY CANYON FIELD, WARD COUNTY,  TEXAS. In connection with the
acquisition of the West Texas  Properties in July 1994, the Company  acquired an
interest in approximately  7,360 gross acres (4,500 net acres) in this field and
currently operates 20 of the wells in its acreage. The Company drilled its first
shallow pool exploratory test well in this field in March 1995. Since that time,
this field has become the principal focus of the Company's development activity.
To date,  24  wells  have  been  drilled  and  completed  in one or more  sands,
including the Bell Canyon,  Cherry  Canyon and Brushy  Canyon Sands.  Four other
sands have been production tested with additional sands remaining behind pipe to
be tested in the future.  The Company is currently  attempting to delineate this
field by  drilling  wells in several  different  areas.  The Company has not yet
drilled any dry holes in this field. Two wells have been drilled by Chevron USA,
Inc. and Southwest  Royalties,  Inc.  offsetting the Company's acreage.  Both of
these  wells are  currently  being  completed  and, if  successful,  could prove
additional  locations on the Company's acreage. At June 30, 1996, this field had
estimated net proved  reserves of 3,647 MBOE (50.4% natural gas) with a PV-10 of
$20.3 million, 73.0% of which was attributable to proved developed reserves. For
the nine months  ended  September  30, 1996,  this field  produced an average of
approximately 256 net Bbls of crude oil and NGLs and approximately 1,417 net Mcf
of natural gas per day from 11.1 net wells.

        DELAWARE AREA (HOWE,  ROC,  BLOCK 16,  TAURUS,  GOMEZ AND NINE MILE DRAW
FIELDS),  WARD,  REEVES,  AND PECOS  COUNTIES,  TEXAS.  In  connection  with the
acquisition  of the West Texas  Properties  in July 1994,  the Company  acquired
working interests ranging from 18% to 100% in 35 wells, 29 of which are operated
by the Company.  These fields produce from Devonian,  Wolfcamp,  Ellenburger and
Cherry Canyon  formations  at depths  ranging from 6,500 feet to 17,600 feet. At
June 30, 1996,  these fields had  estimated  total net proved  reserves of 3,644
MBOE  (83.4%  natural  gas)  with a PV-10 of $17.3  million,  100% of which  was
attributable to proved developed  reserves.  For the nine months ended September
30, 1996,  these  fields  produced an average of  approximately  127 net Bbls of
crude oil and NGLs and 4,253 net Mcf of natural gas per day from 21.1 net wells.

        PORTILLA  FIELD,  SAN PATRICIO  COUNTY,  TEXAS.  The Company  originally
acquired a 50% working  interest in Portilla in April 1993.  In March 1996,  the
Company sold its interest in Portilla to Acco, which subsequently contributed it
to the Partnership.  In September 1996, the Company entered into an agreement to
reacquire  Portilla,  including the 50% interest previously owned by the Pension
Fund.  See "--  Recent  Acquisitions  --  Portilla  and  Happy."  This field was
discovered  in the 1950's by Superior  Oil Company and  produces  from  numerous
Miocene, Frio and Vicksburg age sands at depths ranging from 4,000 feet to 9,000
feet. At June 30, 1996,  this field had  estimated net proved  reserves of 4,134
MBOE  (19.2%  natural  gas)  with a PV-10 of $28.2  million,  99.8% of which was
attributable to proved developed  reserves.  For the nine months ended September
30, 1996, the field produced an average of  approximately  872 net Bbls of crude
oil and NGLs and  approximately  1.957 net Mcf of natural  gas per day from 51.0
net wells.  The Company  owns a 100%  interest in the  Portilla  Plant which had
aggregate  capacity  of  approximately  20.0  MMcf  of  natural  gas  per day at
September  30,  1996.  During the nine months  ended  September  30,  1996,  the
Portilla Plant  processed an average of  approximately  17.2 MMcf of natural gas
per day and extracted an average of approximately  271 Bbls of NGLs per day. The
Company is currently the operator of the Portilla  Plant and all of the wells in
the Portilla Field.

        EAST  WHITE  POINT  FIELD,  SAN  PATRICIO  COUNTY,  TEXAS.  The  Company
originally  acquired an approximate 30% working  interest in this field in April
1993.  The field  produces  crude oil and natural gas from numerous sands in the
Lower Frio  formation at depths  ranging from 9,000 feet to 13,000 feet. At June
30,  1996,  this field had  estimated  net proved  reserves of 8,191 MBOE (61.0%
natural gas) with a PV-10 of $45.9 million,  74.2% of which was  attributable to
proved  developed  reserves.  The Company  operates 11 wells in this field,  and
Marathon  Oil Company  ("Marathon")  operates 10  additional  wells in which the
Company has an interest.  For the nine months  ended  September  30, 1996,  this
field  produced an average of  approximately  461 Net Bbls of crude oil and NGLs
and 3,544 net Mcf of natural gas per day from 5.7 net wells.  The  Company  also
owns an  approximate  38.4%  interest in and  operates a natural gas  processing
plant in this field. The East White Point natural gas processing plant, a modern
cyrogenic plant with capacity of  approximately  25 MMcf of natural gas per day,
processed  an average  of  approximately  11.6 MMcf of  natural  gas per day and
extracted  approximately  679  Bbls of NGLs per day for the  nine  months  ended
September 30, 1996.

        STEDMAN  ISLAND FIELD,  NUECES  COUNTY,  TEXAs.  The Company  originally
acquired a 25% working  interest  in this field in April 1993 and an  additional
25% in October  1995.  This field  produces  crude oil and natural gas from Frio
sands at depths  ranging from 8,500 feet to 10,000 feet. At June 30, 1996,  this
field had estimated net proved reserves of 2,305 MBOE (67.6% natural gas) with a
PV-10 of $12.3  million,  62.6% of which was  attributable  to proved  developed
reserves.  For the nine months ended  September 30, 1996, this field produced an
average  of  approximately  42 net Bbls of crude oil and NGLs and 913 net Mcf of
natural  gas per day from 2.5 net wells.  In July  1996,  the  Company  placed a
successful  recompletion  well  on  production  which  produced  an  average  of
approximately  20 net Bbls of crude oil and 800 net Mcf of  natural  gas per day
during the  balance  of the month of July and  during  August and 13 net Bbls of
crude oil and 665 net Mcf of natural  gas per day  during  September  1996.  The
Company  believes  that  additional  productive  zones remain  behind pipe.  Two
additional  workovers  have been  identified  and are  expected to be  completed
during the first quarter of 1997. The Company has also  identified a potentially
significant  exploratory  location  using  recently  acquired  and  re-processed
seismic data in a horizon  below current  production  in the field.  The seismic
data  indicates the presence of an untested fault block in the deeper Frio sands
and the Company plans to drill a test well during the fourth quarter 1996.

        SPRABERRY TREND FIELD, MIDLAND, MARTIN AND REAGAN COUNTIES, TEXAS. Since
January 1, 1991,  the Company has  acquired  interests  in or drilled  eight new
wells in this field.  This field  produces at depths  ranging from 8,000 feet to
9,100 feet in multiple  sands.  The Company  owns  interests in 30 wells in this
field,  15 of which  are  operated  by the  Company.  Following  the  successful
completion  of two wells  during the second  quarter of 1996,  eight  additional
proved  undeveloped  locations  were  identified  by the  Company's  independent
petroleum  engineers.  At June 30,  1996,  this field had  estimated  net proved
reserves of 1,335 MBOE (27.0%  natural gas) with a PV-10 of $7.1 million,  78.5%
of which was  attributable  to proved  developed  reserves.  For the nine months
ended September 30, 1996, the field produced an average of approximately 150 net
Bbls of crude oil and NGLs and  approximately  351 net Mcf  natural  gas per day
from 17.4 net wells.

        SHARON RIDGE AND WESTBROOK FIELDS, SCURRY AND MITCHELL COUNTIES,  TEXAS.
The Company  drilled its first wells in the Westbrook Field in 1978 and operated
approximately  40 wells prior to 1992.  These two fields  produce crude oil from
Permian age carbonates at depths ranging from 1,700 feet to 3,500 feet. In 1992,
the Company acquired working interests ranging from 57.5% to 100% and became the
operator  of 124 wells in the  Sharon  Ridge  Field,  which is  adjacent  to the
Westbrook  Field. At June 30, 1996,  these fields had estimated total net proved
reserves of 991 MBOE (5.1% natural gas) with a PV-10 of $5.2  million,  75.1% of
which was attributable to proved developed  reserves.  For the nine months ended
September 30, 1996,  these fields produced an average of  approximately  200 net
Bbls of crude oil and NGLs per day from 89.0 net wells. The Company is currently
investigating  production enhancement efforts in this field, which could include
waterflooding and development drilling.

SOUTHWESTERN WYOMING

        The Company acquired the Wyoming  Properties in September 1996. See " --
Recent  Activities."  The Wyoming  Properties  produce natural gas from numerous
sands at depths  ranging from 8,500 feet to 12,000 feet.  At June 30, 1996,  the
Wyoming  Properties had estimated total net proved reserves of 9,935 MBOE (68.5%
natural  gas)  with a PV-10 of $30.3  million  (based,  in part,  on an  assumed
natural gas price of $1.07 per Mcf),  97.3% of which was  attributable to proved
developed  reserves.  For the nine months ended  September 30, 1996, the Wyoming
Properties  produced an average of  approximately  997 net Bbls of crude oil and
NGLs and 12,477 net Mcf of natural gas per day from 22.0 net wells.

WESTERN CANADA

        PRODUCING PROPERTIES. In January 1996, the Company invested $3.0 million
in  Grey  Wolf  Exploration  Ltd.  ("Grey  Wolf"),  a  privately  held  Canadian
corporation,  which, in turn,  invested these proceeds in newly-issued shares of
Cascade,  an  Alberta-based  corporation  whose common  shares are traded on The
Alberta  Stock  Exchange  under the symbol  "COL." The  Company  owns 78% of the
outstanding  capital stock of Grey Wolf and, through Grey Wolf, the Company owns
approximately 52% of the outstanding capital stock of Cascade. Cascade owns 30.0
gross (4.3 net to Cascade)  producing crude oil and natural gas wells and 12,000
net  acres of  undeveloped  leases in  southwestern  Saskatchewan.  These  wells
produce crude oil from multiple sands at depths ranging from 4,200 feet to 4,600
feet. A report  prepared by Cascade's  independent  petroleum  engineers  showed
estimated net proved  reserves of 141 MBbls of crude oil with a PV-10 of CDN$1.4
million,  or approximately  U.S.$0.9 million,  at January 1, 1996. None of these
reserves  or values  are  included  in the report of the  Company's  independent
petroleum engineers. See " -- Reserves Information." Cascade has drilled one dry
exploratory  well and Grey Wolf has drilled  six  successful  development  wells
during 1996. As of December 17, 1996,  the market value of the shares of Cascade
held by Grey Wolf was CDN$20.5  million,  or  approximately  U.S.$15.0  million,
based on the  closing  price per share of  Cascade  stock on The  Alberta  Stock
Exchange on such date.

        In November  1996,  Canadian  Abraxas  acquired CGGS. As of September 1,
1996, the Canadian Abraxas Properties had estimated total net proved reserves of
10,821 MBOE (91.7%  natural gas) with a PV-10 of $46.4  million,  82.4% of which
was  attributable  to  proved  developed  reserves.  For the nine  months  ended
September  30, 1996,  the  Canadian  Abraxas  Properties  produced an average of
approximately  600 net Bbls of crude oil and NGLs and 35.5net Mcf of natural gas
per day from 68.8 net wells. See "-- Recent Acquisitions."

        NATURAL GAS PROCESSING. Canadian Abraxas natural gas processing business
includes natural gas gathering and processing operations.  Natural gas gathering
operations  involve  locating and contracting for natural gas supplies  produced
from crude oil and natural gas fields and the  operation  and  maintenance  of a
gathering  system of pipelines  that connect such natural gas supply  sources to
natural gas  processing  plants.  Natural  gas  processing  involves  subjecting
natural  gas to high  pressure  and low  temperature  treatments  that cause the
natural  gas to  separate  into  various  products,  including a mixture of NGLs
(commonly referred to as raw product), residual natural gas and by-products such
as helium,  condensate and sulfur.  The combined  value of the residual  natural
gas, raw product and  by-products  is generally  higher than that of unprocessed
natural  gas.  Certain of Canadian  Abraxas'  processing  plants are equipped to
fractionate  the raw product  into its  component  products of ethane,  propane,
butanes and natural gasoline for sale to local markets.

        The Company  believes  that the  Canadian  Abraxas  Plants will  provide
substantial  revenue-enhancing  opportunities  to the  Company.  Several  of the
plants are located in areas with little or no competition from other natural gas
processing plants. The Company intends to utilize the plants' excess capacity by
seeking to process  additional  natural gas volumes from third  parties and from
increased production from the Canadian Abraxas Properties.  The Company believes
that its ownership of the Canadian  Abraxas  Properties and the Canadian Abraxas
Plants will afford it a competitive  advantage  relative to other area operators
due to the Company's  preferential access to the natural gas processing capacity
at these facilities.

        For the nine months  ended  September  30, 1996,  the  Canadian  Abraxas
Plants  processed an average of 182.8 MMcf of natural gas per day (65.7 MMcf per
day net to CGGS),  of which  19.2%  (39.2% net) was custom  processed  for third
parties.  The following table sets forth certain information with respect to the
Canadian Abraxas Plants for the nine months ended September 30, 1996.

EXPLORATION OPPORTUNITIES

        The Company allocates a portion of its capital budget to the drilling of
exploratory wells which have high reserve  potential.  The Company believes that
by  devoting a  relatively  small  amount of capital to high  impact,  high risk
projects while  reserving the majority of its available  capital for development
projects,  it can  reduce  its risk  profile  while  still  benefiting  from the
potential for  significant  reserve  additions.  Some of the  Company's  current
exploration opportunities include the following:

        YOAKUM PROSPECT,  DEWITT COUNTY, TEXAS. The Company owns a 100% interest
in  approximately  952 acres and intends to drill a 15,000 foot step-out well to
the Yoakum (Edwards) Field. The test will attempt to extend existing  production
in the Edwards Field onto the Company's acreage.  Offsetting wells have produced
as much as 5,000 Mcf of natural gas per day. This well is expected to be drilled
in the fourth quarter of 1996.

        ROCHE RANCH, REFUGIO COUNTY,  TEXAS. The Company owns a 100% interest in
approximately  416 acres and intends to drill a 7,500 foot Frio test well during
the fourth quarter of 1996.  This prospect is located  approximately  five miles
north of Portilla.

        SHANGHAI FIELD, WHARTON COUNTY,  TEXAS. The Company owns a 20.0% working
interest in the Shanghai  Prospect.  Following two inconclusive wells drilled in
1994, the Company  participated  in an expansive 3-D seismic shoot.  The seismic
data was recently  processed and interpreted.  During the third quarter of 1996,
the Company intends to drill a third well in the field on a directional basis to
test four potential Yegua Sands.

        JEAN PROSPECT, YOUNG COUNTY, TEXAS. As many as five additional locations
delineated by 3D seismic  remain to be drilled on the 1,800 acre Jean 3D seismic
project in the Mississippi and Caddo Formations at approximately 4,500 feet. The
Company owns a 25.0%  working  interest  and 18.8% net revenue  interest in this
project.

RESERVES INFORMATION

        The  crude  oil and  natural  gas  reserves  of the  Company  have  been
estimated as of January 1, 1995, and January 1, 1996, and June 30, 1996, and the
crude oil and natural gas  reserves of the Wyoming  Properties  and Portilla and
Happy have been  estimated  as of June 30,  1996,  by  DeGolyer  &  MacNaughton,
Dallas,  Texas.  The  crude  oil and  natural  gas  reserves  of CGGS  have been
estimated as of  September  1, 1996,  by Sproule  Associates  Limited,  Calgary,
Alberta,  Canada.  Crude oil and natural gas reserves,  and the estimates of the
present value of future net revenue  therefrom,  were  determined  based on then
current prices and costs. Reserve  calculations  involved the estimate of future
net recoverable  reserves of crude oil and natural gas and the timing and amount
of future net revenue to be received  therefrom.  Such estimates are not precise
and are based on assumptions  regarding a variety of factors,  many of which are
variable and uncertain.

        The following table sets forth certain  information  regarding estimates
of the Company's crude oil, NGLs and natural gas reserves as of January 1, 1995,
January  1, 1996 and June 30,  1996,  on a  historical  basis and on a pro forma

        There are numerous  uncertainties  inherent in estimating  quantities of
proved  reserves and in projecting  future rates of production and the timing of
development  expenditures,  including  many  factors  beyond the  control of the
Company.  The reserve data included in this Prospectus represent only estimates.
In addition,  the  estimates  of future net revenue from proved  reserves of the
Company and the present value thereof are based upon certain  assumptions  about
future  production  levels,  prices,  and costs that may not prove to be correct
over time.  In  particular,  estimates  of crude oil and natural  gas  reserves,
future net revenue from proved  reserves and the PV-10 thereof for the Company's
crude oil and natural gas  properties  included in this  Prospectus are based on
the  assumption  that future oil and gas prices remain the same as crude oil and
natural gas prices at June 30,  1996,  with  respect to the  Company's  existing
properties  and for  Portilla  and  Happy,  and for the  month of July 1996 with
respect to the Canadian Abraxas Properties.  The average sales prices as of such
dates used for  purposes  of such  estimates  were  $19.86 per Bbl of crude oil,
$14.09  per Bbl of NGLs and $1.27 per Mcf of  natural  gas with  respect  to the
Canadian Abraxas Properties,  $21.70 per Bbl of crude oil, $9.25 per Bbl of NGLs
and $1.07 per Mcf of natural gas with respect to the Wyoming Properties,  $19.98
per Bbl of crude oil,  $14.50  per Bbl of NGLs and $2.65 per Mcf of natural  gas
with respect to Portilla  and Happy and $20.64 per Bbl of crude oil,  $12.38 per
Bbl of NGLs and $2.29 per Mcf of natural gas with respect to the Company's other
properties in the aggregate. Also assumed is the Company's making future capital
expenditures  of  approximately  $19.7 million in the aggregate,  including $3.4
million  on  the  Wyoming  Properties,  $1.7  million  on the  Canadian  Abraxas
Properties  and $2.2  million on Portilla  and Happy,  necessary  to develop and
realize the value of its undeveloped reserves. Any significant variance in these
assumptions could materially affect the estimated quantity and value of reserves
set forth  herein.  See  "Management's  Discussion  and  Analysis  of  Financial
Condition and Results of Operations."

        In  general,  the volume of  production  from crude oil and  natural gas
properties  declines as reserves are depleted.  Except to the extent the Company
acquires   properties   containing   proved  reserves  or  conducts   successful
exploration  and  development  activities,  or both, the proved  reserves of the
Company will decline as reserves are produced.  The  Company's  future crude oil
and natural gas  production  is  therefore  highly  dependent  upon its level of
success in acquiring or finding additional reserves.

        The Company  files  reports of its  estimated  crude oil and natural gas
reserves  with the  Department  of  Energy  and the  Bureau of the  Census.  The
reserves  reported  to these  agencies  are  required  to be reported on a gross
operated  basis and  therefore  are not  comparable to the reserve data reported
herein.

MARKETS AND CUSTOMERS

        The revenue  generated by the Company's  operations are highly dependent
upon the prices of, and demand for crude oil and natural gas. Historically,  the
markets  for crude oil and  natural  gas have been  volatile  and are  likely to
continue to be volatile  in the future.  The prices  received by the Company for
its crude oil and natural gas  production  and the level of such  production are
subject to wide fluctuations and depend on numerous factors beyond the Company's
control  including  seasonality,  the  condition  of the United  States  economy
(particularly the manufacturing sector),  foreign imports,  political conditions
in other oil-producing and natural gas-producing  countries,  the actions of the
Organization  of  Petroleum   Exporting   Countries  and  domestic   regulation,
legislation  and policies.  Decreases in the prices of crude oil and natural gas
have had, and could have in the future,  an adverse effect on the carrying value
of the Company's proved reserves and the Company's  revenue,  profitability  and
cash flow from operations.

        In order to manage its  exposure to price risks in the  marketing of its
crude oil and natural  gas, the Company from time to time has entered into fixed
price delivery contracts,  financial swaps and crude oil and natural gas futures
contracts as hedging devices. To ensure a fixed price for future production, the
Company may sell a futures  contract  and  thereafter  either (i) make  physical
delivery of crude oil or natural gas to comply with such  contract or (ii) buy a
matching futures contract to unwind its futures position and sell its production
to a customer.  Such  contracts  may expose the Company to the risk of financial
loss in certain circumstances, including instances where production is less than
expected,  the Company's  customers  fail to purchase or deliver the  contracted
quantities of crude oil or natural gas, or a sudden, unexpected event materially
impacts  crude oil or natural gas prices.  Such  contracts may also restrict the
ability of the Company to benefit  from  unexpected  increases  in crude oil and
natural gas prices.

        In connection  with the Acco Sale,  Acco entered into a commodity  price
hedge with Christiania which was assumed by the Company and BTCo and ING Capital
in connection with the consummation of the Transactions. Under the terms of this
commodity  price  hedge,  the Company is required to receive or make  payment to
BTCo and ING Capital based on a differential  between a fixed and variable price
for crude oil and natural gas through the last  business day of November 2001 on
volumes  ranging from 8,160 barrels of crude oil to 20,000  barrels of crude oil
per month and 14,850  MMBTU of natural  gas to 87,406  MMBTU of natural  gas per
month.  Under this  agreement,  the Company  receives  fixed prices ranging from
$17.20  per barrel of crude oil to $18.55 per barrel of crude oil and $1.793 per
MMBTU of natural gas to $1.925 per MMBTU of natural gas and makes payments based
on the price for west Texas  intermediate light sweet crude oil on the NYMEX for
crude oil and the Inside FERC,  Tennessee  Gas Pipeline Co: Texas (Zone 0) price
for natural gas.

        Substantially  all of the Company's crude oil and natural gas is sold at
current  market  prices  under  short term  contracts,  as is  customary  in the
industry. During the year ended December 31, 1995, five purchasers accounted for
approximately  64% of the Company's crude oil and natural gas sales. The Company
believes  that there are  numerous  other  companies  available  to purchase the
Company's  crude  oil and  natural  gas and that the loss of any or all of these
purchasers would not materially  affect the Company's  ability to sell crude oil
and natural gas.

        In Fiscal 1995,  CGGS sold its NGLs and natural gas to a combination  of
aggregators,  short-term and longer-term  Canadian and United States  customers.
Pricing  terms in these  contracts  included  a mixture  of fixed  and  floating
prices. CGGS received an average of $0.94 per Mcf for its natural gas production
in Fiscal 1995.  For the nine months ended  October 31, 1996,  CGGS  received an
average of $1.24 per Mcf of natural gas as a result of utilizing certain hedging
arrangements.  During  Fiscal 1995,  14  purchasers  accounted for 100% of CGGS'
crude oil, NGLs and natural gas sales,  and during the nine months ended October
31,  1996,  eight  purchasers  accounted  for 100% of CGGS' crude oil,  NGLs and
natural gas sales.

        The Company  believes that expected  improvements in the  transportation
infrastructure in, and increased demand for natural gas from,  southwest Wyoming
and Alberta,  Canada will help to reduce the existence of basis differentials in
the pricing of natural gas produced in these areas. With basis  differentials at
relatively  high  historical  levels,  the Company  believes  that the  Canadian
Abraxas  Properties and the Wyoming Properties have the potential for increasing
revenue and asset value as these differentials  decrease without any increase in
LOE and G&A expenses.

COMPETITION

        The Company  encounters strong  competition from major oil companies and
independent  operators in acquiring  properties  and leases for the  exploration
for, and production of, crude oil and natural gas.  Competition is  particularly
intense with respect to the acquisition of desirable  undeveloped  crude oil and
natural gas leases. The principal competitive factors in the acquisition of such
undeveloped  crude  oil and  natural  gas  leases  include  the  staff  and data
necessary to identify,  investigate and purchase such leases,  and the financial
resources  necessary to acquire and develop such leases.  Many of the  Company's
competitors have financial resources, staff and facilities substantially greater
than those of the Company. In addition, the producing,  processing and marketing
of crude oil and natural gas is affected by a number of factors which are beyond
the control of the Company, the effect of which cannot be accurately predicted.

        The principal raw materials and resources  necessary for the exploration
and production of crude oil and natural gas are leasehold  prospects under which
crude oil and natural gas reserves may be discovered,  drilling rigs and related
equipment to explore for such  reserves and  knowledgeable  personnel to conduct
all phases of crude oil and natural gas operations. The Company must compete for
such raw  materials  and  resources  with both  major  crude oil  companies  and
independent  operators.  Although the Company believes its current operating and
financial  resources are adequate to preclude any significant  disruption of its
operations in the immediate future, the continued availability of such materials
and resources to the Company cannot be assured.

        The Company will face significant  competition for obtaining  additional
natural gas supplies for  gathering  and  processing  operations,  for marketing
NGLs, residue gas, helium,  condensate and sulfur, and for transporting  natural
gas  and  liquids.  The  Company's  principal  competitors  will  include  major
integrated oil companies and their  marketing  affiliates and national and local
gas gatherers,  brokers,  marketers and distributors of varying sizes, financial
resources  and  experience.  Certain  competitors,  such as major  crude oil and
natural gas companies,  have capital  resources and control  supplies of natural
gas substantially greater than the Company. Smaller local distributors may enjoy
a marketing advantage in their immediate service areas. The Company will compete
against other companies in its natural gas processing business both for supplies
of natural gas and for customers to which it will sell its products. Competition
for natural gas supplies is based primarily on location of natural gas gathering
facilities  and  natural  gas  gathering   plants,   operating   efficiency  and
reliability and ability to obtain a satisfactory  price for products  recovered.
Competition for customers is based primarily on price and delivery capabilities.

REGULATORY MATTERS

        The  Company's  operations  are  affected  from time to time in  varying
degrees by political developments and federal,  state, provincial and local laws
and regulations.  In particular, oil and gas production operations and economics
are, or in the past have been, affected by price controls, taxes,  conservation,
safety,  environmental,  and other laws relating to the petroleum  industry,  by
changes in such laws and by constantly changing administrative regulations.

        PRICE REGULATIONS

        In the recent past,  maximum  selling  prices for certain  categories of
crude oil, natural gas,  condensate and NGLs were subject to federal regulation.
In 1981, all federal price controls over sales of crude oil, condensate and NGLs
were lifted.  Effective January 1, 1993, the Natural Gas Wellhead  Decontrol Act
(the "Decontrol  Act")  deregulated  natural gas prices for all "first sales" of
natural gas, which includes all sales by the Company of its own production. As a
result, all sales of the Company's domestically produced crude oil, natural gas,
condensate and NGLs may be sold at market prices,  unless otherwise committed by
contract.

        Natural  gas  exported  from  Canada is  subject  to  regulation  by the
National  Energy Board ("NEB") and the government of Canada.  Exporters are free
to  negotiate  prices and other  terms with  purchasers,  provided  that  export
contracts  in  excess  of two  years  must  continue  to meet  certain  criteria
prescribed by the NEB and the  government  of Canada.  As is the case with crude
oil, natural gas exports for a term of less than two years must be made pursuant
to an NEB order, or, in the case of exports for a longer  duration,  pursuant to
an NEB license and Governor in Council approval.

        The  government of Alberta also regulates the volume of natural gas that
may be removed from Alberta for  consumption  elsewhere based on such factors as
reserve availability, transportation arrangements and marketing considerations.

        THE NORTH AMERICAN FREE TRADE AGREEMENT

        On January 1, 1994,  the North American Free Trade  Agreement  ("NAFTA")
among the governments of the United States,  Canada and Mexico became effective.
In the context of energy  resources,  Canada  remains free to determine  whether
exports  to the  U.S.  or  Mexico  will be  allowed  provided  that  any  export
restrictions  do not: (i) reduce the  proportion  of energy  resources  exported
relative to the total supply of the energy  resource  (based upon the proportion
prevailing  in the most recent 36 month  period);  (ii)  impose an export  price
higher than the domestic price; or (iii) disrupt normal channels of supply.  All
three  countries are  prohibited  from imposing  minimum  export or import price
requirements.

        NAFTA contemplates the reduction of Mexican  restrictive trade practices
in the energy sector and prohibits discriminatory border restrictions and export
taxes.  The agreement  also  contemplates  clearer  disciplines on regulators to
ensure fair  implementation of any regulatory changes and to minimize disruption
of  contractual  arrangements,  which is  important  for  Canadian  natural  gas
exports.

        NATURAL GAS REGULATION

        Historically, interstate pipeline companies generally acted as wholesale
merchants by  purchasing  natural gas from  producers  and  reselling the gas to
local distribution  companies and large end users.  Commencing in late 1985, the
Federal Energy Regulatory Commission (the "FERC") issued a series of orders that
have had a major impact on interstate natural gas pipeline operations, services,
and  rates,  and thus have  significantly  altered  the  marketing  and price of
natural gas.  The FERC's key rule making  action,  order No. 636 ("Order  636"),
issued in April 1992,  required each interstate pipeline to, among other things,
"unbundle" its traditional  bundled sales services and create and make available
on an open and  nondiscriminatory  basis numerous  constituent services (such as
gathering  services,  storage services,  firm and  interruptible  transportation
services,  and standby  sales and gas  balancing  services),  and to adopt a new
ratemaking methodology to determine appropriate rates for those services. To the
extent the pipeline  company or its sales affiliate makes natural gas sales as a
merchant,  it does so pursuant to private  contracts in direct  competition with
all of the sellers, such as the Company;  however,  pipeline companies and their
affiliates  were not required to remain  "merchants" of natural gas, and most of
the interstate pipeline companies have become "transporters only." In subsequent
orders,  the FERC largely  affirmed the major features of Order 636 and denied a
stay of the  implementation of the new rules pending judicial review. By the end
of 1994, the FERC had concluded the Order 636 restructuring proceedings, and, in
general,  accepted rate filings implementing Order 636 on every major interstate
pipeline.  However,  even through the  implementation of Order 636 on individual
interstate  pipelines is essentially  complete,  many of the individual pipeline
restructuring  proceedings,  as well as Order  636  itself  and the  regulations
promulgated  thereunder,  are  subject  to  pending  appellate  review and could
possibly  be changed as a result of future  court  orders.  The  Company  cannot
predict whether the FERC's orders will be affirmed on appeal or what the effects
will be on its business.

        In recent  years the FERC also has  pursued a number of other  important
policy  initiatives  which could  significantly  affect the marketing of natural
gas.  Some of the more  notable of these  regulatory  initiatives  include (i) a
series of orders in individual  pipeline  proceedings  articulating  a policy of
generally  approving the voluntary  divestiture  of  interstate  pipeline  owned
gathering  facilities by interstate pipelines to their affiliates (the so-called
"spin down" of  previously  regulated  gathering  facilities  to the  pipeline's
nonregulated  affiliates),  (ii) the  completion  of  rule-making  involving the
regulation of pipelines with marketing affiliates under Order No. 497, (iii) the
FERC's ongoing efforts to promulgate  standards for pipeline electronic bulletin
boards and electronic data exchange,  (iv) a generic inquiry into the pricing of
interstate  pipeline  capacity,  (v)  efforts to refine  the FERC's  regulations
controlling  operation of the secondary market for released  pipeline  capacity,
and  (vi)  a  policy   statement   regarding   market   based  rates  and  other
non-cost-based rates for interstate pipeline  transmission and storage capacity.
Several of these initiatives are intended to enhance  competition in natural gas
markets,  although  some,  such as "spin downs," may have the adverse  effect of
increasing the cost of doing business on some in the industry as a result of the
monopolization of those facilities by their new,  unregulated  owners.  The FERC
has attempted to address some of these concerns in its orders  authorizing  such
"spin downs," but it remains to be seen what effect these  activities  will have
on access to markets and the cost to do business. As to all of these recent FERC
initiatives, the ongoing, or, in some instances,  preliminary evolving nature of
these regulatory  initiatives  makes it impossible at this time to predict their
ultimate impact on the Company's business.

        Recent orders of the FERC have been more liberal in their  reliance upon
traditional  tests for determining what facilities are "gathering" and therefore
exempt  from  federal  regulatory  control.  In many  instances,  what  was once
classified as  "transmission"  may now be classified as "gathering." The Company
transports  certain of its  natural gas through  gathering  facilities  owned by
others,  including  interstate  pipelines,  under existing long term contractual
arrangements.  With respect to item (i) in the preceding  paragraph,  on May 27,
1994,  the FERC issued orders in the context of the "spin off" or "spin down" of
interstate pipeline owned gathering facilities.  A "spin off" is a FERC-approved
sale of such facilities to a non-affiliate. A "spin down" is the transfer by the
interstate  pipeline of its gathering  facilities  to an affiliate.  A number of
spin offs and spindowns have been approved by the FERC and implemented. The FERC
held  that  it  retains  jurisdiction  over  gathering  provided  by  interstate
pipelines,  but  that it  generally  does not have  jurisdiction  over  pipeline
gathering affiliates, except in the event of affiliate abuse (such as actions by
the affiliate  undermining open and  nondiscriminatory  access to the interstate
pipeline).  These  orders  require  nondiscriminatory  access for all sources of
supply and prohibit the tying of pipeline  transportation service to any service
provided by the pipeline's gathering  affiliate.  On November 30, 1994, the FERC
issued a series of rehearing  orders largely  affirming the May 27, 1994 orders.
The FERC now  requires  interstate  pipelines to not only seek  authority  under
Section 7(b) of the Natural Gas Act of 1938 (the "NGA") to abandon  certificated
facilities,  but also to seek authority  under Section 4 of the NGA to terminate
service from both certificated and  uncertificated  facilities.  On December 31,
1994, an appeal was filed with the U.S. Court of Appeals for the D.C. Circuit to
overturn  three of the FERC's  November 30,  1994,  orders.  The Company  cannot
predict what the ultimate  effect of the FERC's  orders  pertaining to gathering
will have on its production and marketing,  or whether the Appellate  Court will
affirm the FERC's orders on these matters.

        STATE AND OTHER REGULATION

        All of the  jurisdictions  in which the Company owns producing crude oil
and natural gas properties have statutory provisions  regulating the exploration
for and production of crude oil and natural gas, including  provisions requiring
permits for the drilling of wells and maintaining bonding  requirements in order
to drill or operate wells and provisions  relating to the location of wells, the
method of  drilling  and  casing  wells,  the  surface  use and  restoration  of
properties  upon which wells are  drilled and the  plugging  and  abandoning  of
wells. The Company's  operations are also subject to various  conservation  laws
and  regulations.  These  include the  regulation  of the size of  drilling  and
spacing  units or proration  units and the density of wells which may be drilled
and the unitization or pooling of crude oil and natural gas properties.  In this
regard,  some  states  allow the  forced  pooling  or  integration  of tracts to
facilitate exploration while other states rely on voluntary pooling of lands and
leases.  In  addition,  state  conservation  laws  establish  maximum  rates  of
production from crude oil and natural gas wells,  generally prohibit the venting
or  flaring  of  natural  gas and  impose  certain  requirements  regarding  the
ratability of  production.  Some states,  such as Texas and  Oklahoma,  have, in
recent years, reviewed and substantially revised methods previously used to make
monthly  determinations  of  allowable  rates  of  production  from  fields  and
individual  wells.  The effect of these  regulations  is to limit the amounts of
crude oil and natural gas the Company can produce  from its wells,  and to limit
the number of wells or the location at which the Company can drill.

        State  regulation of gathering  facilities  generally  includes  various
safety,  environmental,  and  in  some  circumstances,  non-discriminatory  take
requirements,  but  does not  generally  entail  rate  regulation.  Natural  gas
gathering has received greater regulatory scrutiny at both the state and federal
levels in the wake of the interstate pipeline restructuring under Order 636. For
example,   Oklahoma  recently  enacted  a  prohibition  against   discriminatory
gathering rates and certain Texas regulatory  officials have expressed  interest
in evaluating similar rules.

        ROYALTY MATTERS

        UNITED STATES

        By a letter  dated May 3,  1993,  directed  to  thousands  of  producers
holding  interests  in federal  leases,  the  United  States  Department  of the
Interior (the "DOI") announced its  interpretation of existing federal leases to
require the payment of royalties on past natural gas contract  settlements which
were  entered  into in the 1980s  and  1990s to  resolve,  among  other  things,
take-or-pay  and minimum take claims by producers  against  pipelines  and other
buyers.  The DOI's letter sets forth various theories of liability,  all founded
on the DOI's  interpretation  of the term  "gross  proceeds"  as used in federal
leases and pertinent federal  regulations.  In an effort to ascertain the amount
of such  potential  royalties,  the DOI sent a letter to  producers  on June 18,
1993,  requiring  producers  to provide  all data on all  natural  gas  contract
settlements, regardless of whether natural gas produced from federal leases were
involved  in the  settlement.  The Company  received a copy of this  information
demand letter. In response to the DOI's action,  in July 1993,  various industry
associations  and others filed suit in the United States  District Court for the
Northern  District  of West  Virginia  seeking  an  injunction  to  prevent  the
collection  of royalties on natural gas contract  settlement  amounts  under the
DOI's  theories.  The lawsuit,  styled  "Independent  Petroleum  Association  v.
Babbitt," was  transferred  to the United States  District  Court in Washington,
D.C.  On June 4,  1995,  the Court  issued a ruling in this  case  holding  that
royalties  are payable to the United  States on natural gas contract  settlement
proceeds in  accordance  with the  Minerals  Management  Service's  May 3, 1993,
letter to  producers.  This ruling was  appealed  and is now pending in the D.C.
Circuit Court of Appeals.  The DOI's claim in a bankruptcy  proceeding against a
producer based upon an interstate  pipeline's  earlier buy-out of the producer's
natural  gas sale  contract  was  rejected by the  Federal  Bankruptcy  Court in
Lexington,  Kentucky, in a proceeding styled "Century Offshore Management Corp."
While  the  facts  of the  Court's  decision  do not  involve  all of the  DOI's
theories, the Court found on those at issue that the DOI's theories were without
legal merit, and the Court's reasoning  suggests that the DOI's other claims are
similarly  deficient.  This decision was upheld in the District Court and is now
on appeal in the Sixth Circuit Court of Appeals.  Because both the  "Independent
Petroleum  Association  v.  Babbitt" and  "Century  Offshore  Management  Corp."
decisions  have  been  appealed,  and  because  of  the  complex  nature  of the
calculations necessary to determine potential additional royalty liability under
the DOI's  theories,  it is impossible  to predict  what, if any,  additional or
different  royalty  obligation  the DOI may assert or  ultimately be entitled to
recover  with  respect  to any of  the  Company's  prior  natural  gas  contract
settlements.

        CANADA

        In  addition  to  Canadian   federal   regulation,   each  province  has
legislation  and  regulations  that govern land  tenure,  royalties,  production
rates,  environmental  protection  and other  matters.  The royalty  regime is a
significant factor in the profitability of crude oil and natural gas production.
Royalties payable on production from lands other than Crown lands are determined
by  negotiations  between the mineral owner and the lessee.  Crown royalties are
determined  by  governmental  regulation  and  are  generally  calculated  as  a
percentage  of the  value of the  gross  production,  and the rate of  royalties
payable  generally  depends  in  part  on  prescribed  preference  prices,  well
productivity,  geographical  location,  field  discovery  date  and the type and
quality of the petroleum product produced.

        From time to time the  governments of Canada,  Alberta and  Saskatchewan
have established incentive programs which have included royalty rate reductions,
royalty  holidays and tax credits for the purpose of  encouraging  crude oil and
natural gas exploration or enhanced planning projects.

        Regulations  made  pursuant  to the Mines  and  Minerals  Act  (Alberta)
provide  various  incentives for exploring and developing  crude oil reserves in
Alberta.  Crude oil produced from qualifying development wells that were spudded
on or after  November 1, 1991, and prior to August 1, 1993 (or spudded in August
but licensed prior thereto) are eligible for a 12-month royalty  exemption up to
a maximum of CDN$400,000. Exploration wells spudded on or after November 1, 1991
and prior to April 1, 1992,  or if drilled in northern  Alberta or the Foothills
area of Alberta prior to April 1, 1993, are entitled to a 24-month  exemption to
a maximum of CDN$1.0 million.  A 24-month royalty  reduction (up to December 31,
1996) is available for crude oil produced from qualifying  horizontal extensions
commenced  prior  to  January  1,  1995.  Crude  oil  produced  from  horizontal
extensions  commenced at least five years after the well was originally  spudded
may also qualify for a royalty  reduction.  Wells  drilled prior to September 1,
1990, and reactivated  between November 1, 1991 and October 1, 1992,  having had
no production  between September 1, 1990 and November 1, 1991, are entitled to a
five year royalty  exemption to a maximum of 4,000 cubic metres.  An 8,000 cubic
metres  exemption is available to  production  from a well that has not produced
for a 12-month period, if resuming  production in October,  November or December
of 1992 or January  of 1993,  or for a 24-month  period if  resuming  production
after  January 31, 1993.  In addition,  crude oil  production  from eligible new
field and new pool wildcat  wells and deeper pool test wells spudded or deepened
after  September  30, 1992,  is entitled to a 12-month  royalty  exemption (to a
maximum of $1 million). Crude oil produced from low productivity wells, enhanced
recovery  schemes (such as injection  wells) and  experimental  projects is also
subject to royalty reductions.

        The Alberta  government  also  introduced  the Third Tier Royalty with a
base rate of 10% and a rate cap of 25% from oil pools discovered after September
30, 1992. The new oil royalty reserved to the Crown has a base rate of 10% and a
rate cap of 30% and for old oil a base rate of 10% and a rate cap of 35%.

        Effective  January 1, 1994, the  calculation  and payment of natural gas
royalties  became subject to a simplified  process.  The royalty reserved to the
Crown, subject to various incentives,  is between 15% or 30%, in the case of new
natural gas, and between 15% and 35%, in the case of old natural gas,  depending
upon a prescribed or corporate  average  reference  price.  Natural gas produced
from qualifying exploratory gas wells spudded or deepened after July 1, 1985 and
before June 1, 1988  continues  to be  eligible  for a royalty  exemption  for a
period of 12 months,  or such later time that the value of the exempted  royalty
quantity  equals  a  prescribed  maximum  amount.   Natural  gas  produced  from
qualifying  intervals  in eligible  natural  gas wells  spudded or deepened to a
depth below 2,500 meters is also subject to a royalty  exemption,  the amount of
which depends on the depth of the well.

        In Alberta, a producer of crude oil or natural gas is entitled to credit
against the royalties  payable to the Crown by virtue of the Alberta Royalty Tax
Credit ("ARTC") program. The ARTC program is based on a price-sensitive formula,
and the ARTC rate  currently  varies  between 75% for prices for crude oil at or
below  CDN $100 per  cubic  metre  and 35% for  prices  above CDN $210 per cubic
metre.  The ARTC rate is  currently  applied to a maximum of CDN $2.0 million of
Alberta  Crown  royalties  payable  for each  producer  or  associated  group of
producers. Crown royalties on production from producing properties acquired from
corporations claiming maximum entitlement to ARTC will generally not be eligible
for ARTC. The rate is  established  quarterly  based on average "par price",  as
determined  by the  Alberta  Department  of Energy  for the  previous  quarterly
period.

        Crude oil and natural gas royalty  holidays and  reductions for specific
wells reduce the amount of Crown  royalties paid to the provincial  governments.
The ARTC  program  provides  a rebate  on Crown  royalties  paid in  respect  of
eligible producing properties.

        The Government of Saskatchewan revised its fiscal regime for the oil and
gas industry  effective  January 1, 1994. Some royalties on wells existing as of
that date will remain  unchanged  and  therefore  subject to various  periods of
royalty/tax  reduction.  While a number of incentives were eliminated or reduced
(such as incentives for vertical infill wells and lower cost horizontal  wells),
new  incentive  programs were  initiated to encourage  greater  exploration  and
development  activity  in the  province.  The  new  fiscal  regime  provides  an
incentive to encourage  the drilling of new vertical oil wells through a revised
royalty/tax structure for new vertical oil wells and incremental production from
new or expanded  water flood  projects.  This "third tier" Crown royalty rate is
price  sensitive  and varies  between heavy and non-heavy oil (from a minimum of
10% for heavy oil at a base  price to a maximum  of 35% for  non-heavy  oil at a
price above the base price). Previous time-based royalty/tax holidays applicable
to vertically drilled oil wells have been replaced with volume-based royalty/tax
reduction  incentives  in which a maximum  royalty  of 5% will  apply to various
volumes depending on the depth and nature of the well (up to 25,000 cubic metres
of oil in the case of deep exploratory wells). The maximum royalty applicable to
the  first  12,000  cubic  metres of oil has been  increased  from 5% to 10% for
production from certain horizontal wells. In addition,  royalty/tax holidays for
deep  horizontal  oil wells have been replaced with a 25,000 cubic metres volume
incentive (5% maximum royalty).  Oil production from qualifying  reactivated oil
wells are subject to a maximum  new royalty  rate of 5% for the first five years
following  re-activation in the case of wells reactivated after 1993 and shut-in
or suspended  prior to January 1, 1993.  With respect to qualifying  exploratory
natural gas wells,  the first 25 million  cubic  metres of natural gas  produced
will be subject to an incentive maximum royalty rate of 5%.

        ENVIRONMENTAL MATTERS

        The Company's  operations are subject to numerous  federal,  state,  and
local laws and  regulations  controlling  the  discharge of  materials  into the
environment  or  otherwise  relating  to  the  protection  of  the  environment,
including the Comprehensive  Environment Response,  Compensation,  and Liability
Act  ("CERCLA"),  also  known as the  "Federal  Superfund  Law."  Such  laws and
regulations, among other things, impose absolute liability upon the lessee under
a lease  for  the  cost of  clean  up of  pollution  resulting  from a  lessee's
operations,  subject the lessee to liability for pollution damages,  may require
suspension or cessation of operations in affected areas, and impose restrictions
on the  injection  of liquids  into  subsurface  aquifers  that may  contaminate
groundwater.   The  Company  maintains   insurance  against  costs  of  clean-up
operations,  but it's not  fully  insured  against  all such  risks.  A  serious
incident  of  pollution  may,  as it has in the  past,  also  result  in the DOI
requiring  lessees  under  federal  leases to suspend or cease  operation in the
affected  area.  In  addition,  the recent trend  toward  stricter  standards in
environmental legislation and regulation may continue. For instance, legislation
has been  proposed in Congress from time to time that would  reclassify  certain
crude oil and natural gas  production  wastes as "hazardous  wastes" which would
make the  reclassified  exploration  and production  wastes subject to much more
stringent  handling,  disposal,  and clean up requirements.  If such legislation
were  to be  enacted,  it  could  have a  significant  impact  on the  Company's
operating  costs,  as well as the crude oil and natural gas industry in general.
State  initiatives to further regulate the disposal of crude oil and natural gas
wastes are also pending in certain states,  and these various matters could have
a similar impact on the Company.

        The  Company's  Canadian  operations  are also subject to  environmental
regulation  pursuant  to local,  provincial  and federal  legislation.  Canadian
environmental legislation provides for restrictions and prohibitions on releases
or emissions of various  substances  produced in association  with certain crude
oil and natural gas industry operations and can affect the location of wells and
facilities and the extent to which exploration and development is permitted.  In
addition,  legislation  requires that well and facilities sites be abandoned and
reclaimed  to the  satisfaction  of  provincial  authorities.  A breach  of such
legislation  may  result in the  imposition  of fines or  issuance  of  clean-up
orders.  Environmental legislation in Alberta has undergone a major revision and
has been  consolidated in the  Environmental and Enhancement Act . Under the new
Act, environmental standards and compliance for releases, clean-up and reporting
are stricter.  Also, the range of enforcement actions available and the severity
of  penalties  have  been  significantly  increased.  These  changes  will  have
incremental effect on the cost of conducting operations in Alberta.

        The Company is not currently  involved in any administrative or judicial
proceedings  arising  under  domestic  or  foreign  federal,   state,  or  local
environmental  protection  laws and  regulations  which  would  have a  material
adverse effect on the Company's financial position or results of operations.

TITLE TO PROPERTIES

        As is customary in the crude oil and natural gas  industry,  the Company
makes only a cursory  review of title to  undeveloped  crude oil and natural gas
leases at the time they are acquired by the Company.  However,  before  drilling
commences, the Company requires a thorough title search to be conducted, and any
material  defects in title are remedied  prior to the time actual  drilling of a
well on the lease begins.  To the extent title opinions or other  investigations
reflect title defects,  the Company,  rather than the seller of the  undeveloped
property, is typically obligated to cure any title defect at its expense. If the
Company  were unable to remedy or cure any title defect of a nature such that it
would not be  prudent to  commence  drilling  operations  on the  property,  the
Company  could  suffer a loss of its  entire  investment  in the  property.  The
Company  believes  that it has  good  title to its  crude  oil and  natural  gas
properties, some of which are subject to immaterial encumbrances,  easements and
restrictions.  The crude oil and natural gas properties owned by the Company are
also typically  subject to royalty and other similar non-cost bearing  interests
customary  in the  industry.  The  Company  does not  believe  that any of these
encumbrances or burdens will materially affect the Company's ownership or use of
its properties.

EMPLOYMENT AGREEMENTS

        The Company has entered  into  employment  agreements  (the  "Employment
Agreements") with each of Mr. Watson and Mr.  Williford,  pursuant to which each
of Messrs.  Watson and Williford will receive  compensation  as determined  from
time to time by the  Board in its sole  discretion.  The  Employment  Agreements
terminate on December 31, 1996 except that the term of the Employment Agreements
may be  automatically  extended for an  additional  year if by December 1 of the
prior year neither the Company nor Mr. Watson or Mr. Williford,  as the case may
be, has given  notice  that it does not wish to extend  the term.  Except in the
event of a change in  control,  at all times  during the term of the  Employment
Agreements,  each of Mr. Watson's and Mr. Williford's  employment is at will and
may be terminated by the Company for any reason  without  notice or cause.  If a
change in control  occurs  during the term of the  Employment  Agreement  or any
extension thereof,  the expiration date of Mr. Watson's Employment  Agreement is
automatically  extended  to a date no  earlier  than four  years  following  the
effective  date  of such  change  in  control  and  the  expiration  date of Mr.
Williford's  Employment Agreement is automatically extended to a date no earlier
than three years  following  the effective  date of such change in control.  If,
following a change in control,  Mr.  Watson's or Mr.  Williford's  employment is
terminated  other  than  for  Cause  (as  defined  in  each  of  the  Employment
Agreements) or Disability (as defined in each of the Employment Agreements),  by
reason of Mr. Watson's or Mr.  Williford's  death or retirement or by either Mr.
Watson or Mr.  Williford,  as the case may be,  other  than for Good  Reason (as
defined in each of the Employment Agreements),  then Mr. Watson will be entitled
to receive a lump sum payment equal to four times his annual base salary and Mr.
Williford  will be entitled  to receive a lump sum payment  equal to three times
his annual base  salary.  If any such lump sum  payment  would  individually  or
together with any other amounts paid or payable  constitute an "excess parachute
payment"  within the meaning of Section 280G  ("Section  280G") of the Code, and
applicable regulations  thereunder,  the amounts to be paid will be increased so
that Mr.  Watson  or Mr.  Williford,  as the case may be,  will be  entitled  to

                            DESCRIPTION OF THE NOTES

        The Series A Notes were and the  Exchange  Notes will be issued under an
indenture  (the  "Indenture")  dated as of  November  14,  1996 by and among the
Issuers,  the Subsidiary  Guarantors  and IBJ Schroder Bank & Trust Company,  as
Trustee (the  "Trustee").  The  following  summary of certain  provisions of the
Indenture does not purport to be complete and is subject to, and is qualified in
its entirety by reference  to, the Trust  Indenture Act of 1939, as amended (the
"TIA"), and to all of the provisions of the Indenture, including the definitions
of  certain  terms  therein  and those  terms  made a part of the  Indenture  by
reference  to the TIA as in effect on the date of the  Indenture.  A copy of the
form of Indenture  may be obtained  from the Issuers or the Initial  Purchasers.
The definitions of certain  capitalized  terms used in the following summary are
set forth below under "-- Certain Definitions."

        The Series A Notes were and the Exchange Notes will be general unsecured
obligations  of the  Issuers and will rank pari passu in right of payment to all
existing and future  unsubordinated  obligations  of the  Issuers.  The Series A
Notes rank and the  Exchange  Notes will rank  senior in right of payment to all
future subordinated indebtedness of the Issuers. The Series A Notes are, and the
Exchange Notes will be, however, effectively subordinated in right of payment to
all existing and future secured indebtedness of the Issuers to the extent of the
value of the assets securing such  indebtedness.  The Guarantees will be general
unsecured  obligations of the Subsidiary Guarantors and rank pari passu in right
of  payment  to all  existing  and  future  unsubordinated  indebtedness  of the
Subsidiary  Guarantors and senior in right of payment to all existing and future
subordinated  indebtedness of the Subsidiary Guarantors.  The Guarantees will be
effectively subordinated to secured indebtedness of the Subsidiary Guarantors to
the extent of the value of the assets securing such indebtedness.

        The Series A Notes were and the  Exchange  Notes will be issued in fully
registered form only,  without coupons,  in denominations of $1,000 and integral
multiples thereof.  The Trustee currently acts as paying agent and registrar for
the Notes.  The Notes may be presented for registration of transfer and exchange
at the offices of the registrar, which initially will be the Trustee's corporate
trust  office.  The Issuers may change any paying  agent and  registrar  without
notice to holders of the Notes (the  "Holders").  The Issuers will pay principal
(and  premium,  if any) on the Notes at the  Trustee's  corporate  office in New
York,  New York. At the Issuers'  option,  interest may be paid at the Trustee's
corporate  trust  office or by check mailed to the  registered  addresses of the
Holders.  Any Series A Notes that remain outstanding after the completion of the
Exchange  Offer,  together with the Exchange Notes issued in connection with the
Exchange  Offer,  will be  treated  as a single  class of  securities  under the
Indenture. See "Exchange Offer and Registration Rights."

PRINCIPAL, MATURITY AND INTEREST

        The Notes are limited in aggregate  principal amount to $215,000,000 and
will mature on  November 1, 2004.  Interest on the Notes will accrue at the rate
of 11.5% per annum and will be payable  semi-annually  in cash on each May 1 and
November 1, commencing on May 1, 1997, to the Persons who are registered Holders
at  the  close  of  business  on the  April  15 and  October  15,  respectively,
immediately  preceding the  applicable  interest  payment date.  Interest on the
Notes will accrue from and including the most recent date to which  interest has
been paid or, if no  interest  has been  paid,  from and  including  the date of
issuance.

        The Notes will not be entitled to the benefit of any  mandatory  sinking
fund.

REDEMPTION

OPTIONAL REDEMPTION.

        The Notes will be redeemable,  at the Issuers'  option,  in whole at any
time or in part from time to time, on and after November 1, 2000,  upon not less
than 30 nor more  than 60  days'  notice,  at the  following  redemption  prices
(expressed as percentages of the principal  amount  thereof) if redeemed  during
the twelve-month  period  commencing on November 1 of the years set forth below,
plus, in each case, accrued and unpaid interest,  if any, thereon to the date of
redemption:

Year                                                       Percentage
2000                                                       105.750%
2001                                                       102.875%
2002 and thereafter                                        100.000%

OPTIONAL REDEMPTION UPON EQUITY OFFERINGS.

        At any time, or from time to time, on or prior to November 1, 1999,  the
Issuers may, at their  option,  use all or a portion of the net cash proceeds of
one or more  Equity  Offerings  (as  defined  below)  to redeem up to 35% of the
aggregate  principal amount of the Notes originally issued at a redemption price
equal to 111.5% of the aggregate  principal  amount of the Notes to be redeemed,
plus accrued and unpaid  interest,  if any,  thereon to the date of  redemption;
provided,  however,  that at least $139.75 million aggregate principal amount of
Notes remains outstanding immediately after giving effect to any such redemption
(it being  expressly  agreed  that for  purposes  of  determining  whether  this
condition is satisfied,  Notes owned by either Issuer or any of their Affiliates
shall  be  deemed  not to be  outstanding).  In order to  effect  the  foregoing
redemption with the proceeds of any Equity Offering, the Issuers shall make such
redemption  not more than 60 days  after  the  consummation  of any such  Equity
Offering.

SELECTION AND NOTICE OF REDEMPTION

        In the event that less than all of the Notes are to be  redeemed  at any
time,  selection of such Notes, or portions thereof, for redemption will be made
by the Trustee in compliance  with the  requirements  of the principal  national
securities exchange,  if any, on which the Notes are listed or, if the Notes are
not then listed on a national securities  exchange,  on a pro rata basis, by lot
or by such  other  method  as the  Trustee  shall  deem  fair  and  appropriate;
provided,  however,  that no Notes of a principal amount of $1,000 or less shall
be redeemed in part; and provided, further, that if a partial redemption is made
with the  proceeds  of an Equity  Offering,  selection  of the Notes or portions
thereof for redemption  shall be made by the Trustee only on a pro rata basis or
on as nearly a pro rata basis as is  practicable  (subject to the  procedures of
DTC), unless such method is otherwise prohibited.  Notice of redemption shall be
mailed  by  first-class  mail at least 30 but not more than 60 days  before  the
redemption  date to each  Holder  of  Notes  to be  redeemed  at its  registered
address.  If any Note is to be redeemed in part only,  the notice of  redemption
that  relates  to such Note shall  state the  portion  of the  principal  amount
thereof to be redeemed. A new Note in a principal amount equal to the unredeemed
portion  thereof  will  be  issued  in the  name  of  the  Holder  thereof  upon
cancellation of the original Note. On and after the applicable  redemption date,
interest will cease to accrue on Notes or portions thereof called for redemption
as long as the Issuers have  deposited with the paying agent for the Notes funds
in satisfaction of the applicable redemption price pursuant to the Indenture.

GUARANTEES

        Each Subsidiary  Guarantor will unconditionally  guarantee,  on a senior
basis,  jointly  and  severally,  to each Holder and the  Trustee,  the full and
prompt  performance  of the Issuers'  obligations  under the  Indenture  and the
Notes,  including  the payment of principal  of and  interest on the Notes.  The
obligations of each  Subsidiary  Guarantor will be limited to the maximum amount
which, after giving effect to all other contingent and fixed liabilities of such
Subsidiary Guarantor and after giving effect to any collections from or payments
made by or on  behalf  of any  other  Subsidiary  Guarantor  in  respect  of the
obligations of such other  Subsidiary  Guarantor under its Guarantee or pursuant
to  its  contribution  obligations  under  the  Indenture,  will  result  in the
obligations of such Subsidiary  Guarantor under its Guarantee not constituting a
fraudulent  conveyance or fraudulent  transfer  under Federal or state law. Each
Subsidiary  Guarantor that makes a payment or  distribution  under its Guarantee
shall be entitled to a contribution  from each other Subsidiary  Guarantor in an
amount  pro  rata,  based  on the  net  assets  of  each  Subsidiary  Guarantor,
determined in accordance with GAAP.

        Each Subsidiary Guarantor may consolidate with or merge into or sell its
assets to the Company or another  Subsidiary  Guarantor  that is a Wholly  Owned
Restricted  Subsidiary without limitation,  or with or to other Persons upon the
terms and conditions set forth in the  Indenture.  See "-- Certain  Covenants --
Merger, Consolidation and Sale of Assets." In the event all of the Capital Stock
of a  Subsidiary  Guarantor  is sold by the  Company  and/or  one or more of its
Restricted  Subsidiaries  and the sale complies with the provisions set forth in
"-- Certain Covenants -- Limitation on Asset Sales," such Subsidiary Guarantor's
Guarantee will be released.

CHANGE OF CONTROL

        The Indenture  provides that upon the occurrence of a Change of Control,
each Holder will have the right to require  that the Issuers  purchase  all or a
portion  of such  Holder's  Notes  pursuant  to the offer  described  below (the
"Change of Control  Offer"),  at a purchase price equal to 101% of the principal
amount thereof, plus accrued and unpaid interest, if any, thereon to the date of
purchase.

        Within 30 days  following  the date upon  which  the  Change of  Control
occurred,  the Issuers must send,  by first class mail, a notice to each Holder,
with a copy to the Trustee, which notice shall govern the terms of the Change of
Control Offer. Such notice shall state,  among other things,  the purchase date,
which must be no earlier  than 30 days nor later than 45 days from the date such
notice is mailed,  other than as may be required by law (the  "Change of Control
Payment  Date").  A Change of Control Offer shall remain open for a period of 20
Business Days or such longer period as may be required by law.  Holders electing
to have a Note purchased  pursuant to a Change of Control Offer will be required
to  surrender  the  Note,  with the form  entitled  "Option  of  Holder to Elect
Purchase"  on the  reverse of the Note  completed,  to the paying  agent for the
Notes at the address  specified  in the notice prior to the close of business on
the third Business Day prior to the Change of Control Payment Date.

        The Issuers shall not be required to make a Change of Control Offer upon
a Change of Control if a third  party  makes the Change of Control  Offer at the
Change of Control  Purchase Price, at the same times and otherwise in compliance
with the  requirements  applicable  to a Change  of  Control  Offer  made by the
Issuers and purchases all Notes  validly  tendered and not withdrawn  under such
Change of Control Offer.

        If a Change of Control Offer is made, there can be no assurance that the
Issuers  will have  available  funds  sufficient  to pay the  Change of  Control
purchase  price for all the Notes that might be delivered by Holders  seeking to
accept the Change of Control  Offer.  In the event the Issuers  are  required to
purchase  outstanding  Notes pursuant to a Change of Control Offer,  the Issuers
expect that they would seek third party financing to the extent they do not have
available  funds to meet their purchase  obligations.  However,  there can be no
assurance that the Issuers would be able to obtain such financing.

        Neither the Board of  Directors of the Company nor the Trustee may waive
the  covenant  relating to the Issuers'  obligation  to make a Change of Control
Offer.  Restrictions  in the  Indenture  described  herein on the ability of the
Company and its Restricted  Subsidiaries to incur  additional  Indebtedness,  to
grant liens on their  property,  to make  Restricted  Payments and to make Asset
Sales may also make more  difficult  or  discourage  a takeover of the  Company,
whether  favored or opposed  by the  management  of the  Company.  See  "Certain
Antitakeover  Provisions."  Consummation  of any  such  transaction  in  certain
circumstances may require repurchase of the Notes, and there can be no assurance
that the Company or the acquiring party will have sufficient financial resources
to  effect  such   repurchase.   Such   restrictions  and  the  restrictions  on
transactions with Affiliates may, in certain circumstances,  make more difficult
or  discourage  any  leveraged  buyout of the Company by the  management  of the
Company. While such restrictions cover a wide variety of arrangements which have
traditionally been used to effect highly leveraged  transactions,  the Indenture
may not afford the Holders of Notes  protection  in all  circumstances  from the
adverse   aspects   of   a   highly   leveraged   transaction,   reorganization,
restructuring, merger or similar transaction.

        The Issuers  will comply with the  requirements  of Rule 14e-1 under the
Exchange Act and any other  securities  laws and  regulations  thereunder to the
extent  such  laws  and  regulations  are  applicable  in  connection  with  the
repurchase of Notes  pursuant to a Change of Control  Offer.  To the extent that
the provisions of any securities  laws or regulations  conflict with the "Change
of Control"  provisions  of the  Indenture,  the Issuers  shall  comply with the
applicable  securities  laws and  regulations  and  shall  not be deemed to have
breached  its  obligations  under the  "Change  of  Control"  provisions  of the
Indenture by virtue thereof.

CERTAIN COVENANTS

        The Indenture contains, among others, the following covenants:

        LIMITATION  ON  INCURRENCE  OF  ADDITIONAL   INDEBTEDNESS.   Other  than
Permitted  Indebtedness,  the Company will not, and will not cause or permit any
of its  Restricted  Subsidiaries  to,  directly or  indirectly,  create,  incur,
assume,  guarantee,  acquire,  become liable,  contingently  or otherwise,  with
respect  to, or  otherwise  become  responsible  for  payment of  (collectively,
"incur") any  Indebtedness;  provided,  however,  that if no Default or Event of
Default shall have occurred and be continuing at the time of or as a consequence
of the  incurrence  of any such  Indebtedness,  the Company  and the  Restricted
Subsidiaries  or  any  of  them  may  incur  Indebtedness  (including,   without
limitation,  Acquired  Indebtedness),  in  each  case,  if on  the  date  of the
incurrence of such Indebtedness, after giving pro forma effect to the incurrence
thereof and the receipt and application of the proceeds therefrom,  (i) both (a)
the Company's  Consolidated  EBITDA  Coverage Ratio would have been greater than
2.25 to 1.0 if such  proposed  incurrence is on or prior to November 1, 1997 and
at least equal to 2.5 to 1.0 if such proposed  incurrence is thereafter  and (b)
the Company's Adjusted  Consolidated Net Tangible Assets are equal to or greater
than 150% of the  aggregate  consolidated  Indebtedness  of the  Company and its
Restricted Subsidiaries or (ii) the Company's Adjusted Consolidated Net Tangible
Assets  are  equal  to or  greater  than  200%  of  the  aggregate  consolidated
Indebtedness of the Company and its Restricted Subsidiaries.

        For purposes of determining any particular amount of Indebtedness  under
this   covenant,   guarantees  of   Indebtedness   otherwise   included  in  the
determination of such amount shall not also be included.

        Indebtedness  of a Person  existing  at the time such  Person  becomes a
Restricted Subsidiary (whether by merger, consolidation,  acquisition of Capital
Stock or  otherwise)  or is merged  with or into the  Company or any  Restricted
Subsidiary or which is secured by a Lien on an asset  acquired by the Company or
a  Restricted  Subsidiary  (whether or not such  Indebtedness  is assumed by the
acquiring  Person)  shall be deemed  incurred  at the time the Person  becomes a
Restricted  Subsidiary or at the time of the asset acquisition,  as the case may
be.

        The Company  will not, and will not permit any  Subsidiary  Guarantor to
incur any  Indebtedness  which by its  terms  (or by the terms of any  agreement
governing such  Indebtedness)  is  subordinated in right of payment to any other
Indebtedness   of  the  Company  or  such  Subsidiary   Guarantor   unless  such
Indebtedness  is also by its terms (or by the terms of any  agreement  governing
such Indebtedness)  made expressly  subordinate in right of payment to the Notes
or the Guarantee of such Subsidiary  Guarantor,  as the case may be, pursuant to
subordination  provisions that are substantively  identical to the subordination
provisions of such  Indebtedness  (or such agreement) that are most favorable to
the  holders  of any  other  Indebtedness  of the  Company  or  such  Subsidiary
Guarantor, as the case may be.

        LIMITATION  ON RESTRICTED  PAYMENTS.  The Company will not, and will not
cause or permit any of its Restricted  Subsidiaries  to, directly or indirectly,
(a) declare or pay any dividend or make any  distribution  (other than dividends
or distributions payable solely in Qualified Capital Stock of the Company) on or
in respect of shares of the  Company's  Capital Stock to holders of such Capital
Stock, (b) purchase, redeem or otherwise acquire or retire for value any Capital
Stock of the Company or any  warrants,  rights or options to purchase or acquire
shares of any class of such  Capital  Stock  other  than  through  the  exchange
therefor solely of Qualified Capital Stock of the Company or warrants, rights or
options to purchase or acquire shares of Qualified Capital Stock of the Company,
(c) make any principal payment on, purchase,  defease,  redeem, prepay, decrease
or otherwise acquire or retire for value, prior to any scheduled final maturity,
scheduled  repayment or scheduled sinking fund payment,  any Indebtedness of the
Company or a  Subsidiary  Guarantor  that is  subordinate  or junior in right of
payment to the Notes or such Subsidiary Guarantor's  Guarantee,  as the case may
be, or (d) make any Investment (other than a Permitted  Investment) (each of the
foregoing  actions set forth in clauses (a), (b), (c) and (d) being  referred to
as a  "Restricted  Payment"),  if at the  time of  such  Restricted  Payment  or
immediately  after giving effect  thereto,  (i) a Default or an Event of Default
shall have  occurred and be  continuing or (ii) the Company is not able to incur
at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in
compliance with "-- Limitation on Incurrence of Additional  Indebtedness" above;
provided,  however,  that notwithstanding the provisions of clause (i)(a) of "--
Limitation  on Incurrence of  Additional  Indebtedness"  above,  for purposes of
determining  whether  the  Company  could  incur  such  additional  Indebtedness
pursuant to this clause (ii), the Consolidated EBITDA Coverage Ratio which shall
be  required  shall be at least  2.5 to 1.0,  or (iii) the  aggregate  amount of
Restricted Payments (including such proposed Restricted Payment) made subsequent
to the Issue Date (the amount expended for such purposes, if other than in cash,
being the fair market value of such  property as  determined  reasonably  and in
good faith by the Board of Directors  of the  Company)  shall exceed the sum of:
(A) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated
Net  Income  shall be a loss,  minus 100% of such  loss) of the  Company  earned
subsequent  to the Issue Date and on or prior to the last date of the  Company's
fiscal quarter  immediately  preceding such  Restricted  Payment (the "Reference
Date") (treating such period as a single  accounting  period);  plus (B) 100% of
the aggregate  net cash proceeds  received by the Company from any Person (other
than a  Restricted  Subsidiary  of the  Company)  from  the  issuance  and  sale
subsequent to the Issue Date and on or prior to the Reference  Date of Qualified
Capital  Stock of the  Company;  plus (C)  without  duplication  of any  amounts
included in clause  (iii)(B)  above,  100% of the aggregate net cash proceeds of
any equity  contribution  received by the Company from a holder of the Company's
Capital Stock (excluding,  in the case of clauses (iii)(B) and (C), any net cash
proceeds from an Equity  Offering to the extent used to redeem the Notes);  plus
(D) an  amount  equal  to the  net  reduction  in  Investments  in  Unrestricted
Subsidiaries resulting from dividends, interest payments, repayments of loans or
advances,  or other  transfers  of cash,  in each case to the  Company or to any
Restricted Subsidiary of the Company from Unrestricted Subsidiaries (but without
duplication of any such amount included in calculating  cumulative  Consolidated
Net Income of the Company), or from redesignations of Unrestricted  Subsidiaries
as Restricted Subsidiaries (in each case valued as provided in "-- Limitation on
Designation of Unrestricted  Subsidiaries" below), not to exceed, in the case of
any Unrestricted  Subsidiary,  the amount of Investments  previously made by the
Company or any Restricted  Subsidiary in such Unrestricted  Subsidiary and which
was  treated as a  Restricted  Payment  under the  Indenture;  plus (E)  without
duplication of the immediately  preceding  subclause (D), an amount equal to the
lesser  of the  cost or net  cash  proceeds  received  upon  the  sale or  other
disposition of any  Investment  made after the Issue Date which had been treated
as a Restricted Payment (but without  duplication of any such amount included in
calculating  cumulative  Consolidated  Net  Income  of the  Company);  plus  (F)
$5,000,000.

        Notwithstanding   the  foregoing,   the  provisions  set  forth  in  the
immediately  preceding  paragraph  shall not  prohibit:  (1) the  payment of any
dividend or redemption  payment  within 60 days after the date of declaration of
such  dividend  or the  applicable  redemption  if the  dividend  or  redemption
payment,  as the  case  may  be,  would  have  been  permitted  on the  date  of
declaration;  (2) if no Default or Event of Default  shall have  occurred and be
continuing,  the  acquisition  of any  shares of Capital  Stock of the  Company,
either  (A) solely in  exchange  for shares of  Qualified  Capital  Stock of the
Company or (B)  through  the  application  of net  proceeds  of a  substantially
concurrent sale for cash (other than to a Restricted  Subsidiary of the Company)
of shares of Qualified Capital Stock of the Company;  (3) if no Default or Event
of  Default  shall have  occurred  and be  continuing,  the  acquisition  of any
Indebtedness  of the Company or  Subsidiary  Guarantor  that is  subordinate  or
junior  in  right  of  payment  to the  Notes  or  such  Subsidiary  Guarantor's
Guarantee,  as the case may be,  either  (A)  solely in  exchange  for shares of
Qualified  Capital Stock of the Company,  or (B) through the  application of net
proceeds of a substantially concurrent sale for cash (other than to a Restricted
Subsidiary  of the  Company)  of (I) shares of  Qualified  Capital  Stock of the
Company or (II) Refinancing Indebtedness;  (4) if no Default or Event of Default
shall have  occurred and be  continuing,  the payment of dividends in respect of
the Company's  Series 1995-B Preferred Stock in an amount not to exceed $400,000
in any one year, (5) the initial  designation of Grey Wolf,  Cascade and Western
Associated Energy  Corporation as Unrestricted  Subsidiaries under the Indenture
and (6) the payment of such portion of the CGGS purchase price, if any, as shall
have been placed in an escrow  account to the former  shareholders  of CGGS.  In
determining the aggregate  amount of Restricted  Payments made subsequent to the
Issue  Date  in  accordance  with  clause  (iii)  of the  immediately  preceding
paragraph,  amounts  expended  pursuant to clauses (1),  (2)(B) and (5) shall be
included in such calculation.

        LIMITATION  ON ASSET SALES.  The Company will not, and will not cause or
permit any of its Restricted  Subsidiaries  to,  consummate an Asset Sale unless
(a) the Company or the  applicable  Restricted  Subsidiary,  as the case may be,
receives consideration at the time of such Asset Sale at least equal to the fair
market value of the assets sold or otherwise  disposed of (as determined in good
faith by the Company's Board of Directors or senior  management of the Company);
(b) (i) at  least  70% of the  consideration  received  by the  Company  or such
Restricted Subsidiary,  as the case may be, from such Asset Sale shall be in the
form of cash or Cash Equivalents and is received at the time of such disposition
and (ii) at least 15% of such  consideration  received  if in a form  other than
cash  or Cash  Equivalents  is  converted  into or  exchanged  for  cash or Cash
Equivalents  within 120 days of such disposition;  and (c) upon the consummation
of an Asset Sale, the Company shall apply, or cause such  Restricted  Subsidiary
to apply,  the Net Cash Proceeds  relating to such Asset Sale within 365 days of
receipt thereof either (i) to repay or prepay Indebtedness outstanding under the
New Credit Facility, including, without limitation, a permanent reduction in the
related commitment, (ii) to repay or prepay any Indebtedness of the Company that
is secured by a Lien  permitted  to be incurred  pursuant to "--  Limitation  on
Liens"  below,  (iii) to make an investment in properties or assets that replace
the  properties  or  assets  that  were the  subject  of such  Asset  Sale or in
properties  or assets  that will be used in the  business of the Company and its
Restricted  Subsidiaries  as  existing  on  the  Issue  Date  or  in  businesses
reasonably  related  thereto  ("Replacement  Assets"),  (iv) to an investment in
Crude Oil and Natural Gas Related  Assets or (v) a combination of prepayment and
investment  permitted by the foregoing  clauses (c)(i) through  (c)(iv).  On the
366th day after an Asset  Sale or such  earlier  date,  if any,  as the Board of
Directors of the Company  determines not to apply the Net Cash Proceeds relating
to such Asset Sale as set forth in clauses  (c)(i)  through  (c)(iv) of the next
preceding  sentence (each a "Net Proceeds Offer Trigger  Date"),  such aggregate
amount of Net Cash  Proceeds  which have been  received  by the  Company or such
Restricted  Subsidiary  but which have not been  applied  on or before  such Net
Proceeds Offer Trigger Date as permitted in clauses  (c)(i)  through  (c)(iv) of
the next  preceding  sentence  (each a "Net  Proceeds  Offer  Amount")  shall be
applied by the  Company or such  Restricted  Subsidiary,  as the case may be, to
make an offer to purchase (a "Net Proceeds  Offer") on a date (the "Net Proceeds
Offer  Payment  Date")  not less  than 30 nor more  than 45 days  following  the
applicable  Net  Proceeds  Offer  Trigger  Date,  from all Holders on a pro rata
basis,  that principal  amount of Notes  purchasable with the Net Proceeds Offer
Amount  at a price  equal to 100% of the  principal  amount  of the  Notes to be
purchased,  plus  accrued and unpaid  interest,  if any,  thereon to the date of
purchase;  provided,  however,  that if at any time any  non-cash  consideration
received by the  Company or any  Restricted  Subsidiary,  as the case may be, in
connection  with any Asset Sale is converted into or sold or otherwise  disposed
of for cash (other than  interest  received  with  respect to any such  non-cash
consideration),   then  such  conversion  or  disposition  shall  be  deemed  to
constitute an Asset Sale  hereunder  and the Net Cash Proceeds  thereof shall be
applied in accordance with this covenant. The Company may defer the Net Proceeds
Offer until there is an aggregate  unutilized Net Proceeds Offer Amount equal to
or in excess of  $5,000,000  resulting  from one or more  Asset  Sales (at which
time, the entire  unutilized Net Proceeds Offer Amount,  and not just the amount
in  excess  of  $5,000,000,  shall  be  applied  as  required  pursuant  to this
paragraph).

        In the event of the transfer of  substantially  all (but not all) of the
property  and  assets  of the  Company  and its  Restricted  Subsidiaries  as an
entirety to a Person in a transaction permitted under "-- Merger,  Consolidation
and Sale of Assets," the successor  corporation shall be deemed to have sold the
properties  and assets of the Company  and its  Restricted  Subsidiaries  not so
transferred for purposes of this covenant,  and shall comply with the provisions
of this  covenant  with respect to such deemed sale as if it were an Asset Sale.
In addition,  the fair market value of such properties and assets of the Company
or its Restricted  Subsidiaries deemed to be sold shall be deemed to be Net Cash
Proceeds for purposes of this covenant.

        Notwithstanding the two immediately  preceding  paragraphs,  the Company
and its  Restricted  Subsidiaries  will be permitted to consummate an Asset Sale
without  complying with such paragraphs to the extent (a) the  consideration for
such Asset Sale constitutes  Replacement Assets and/or Crude Oil and Natural Gas
Related  Assets  and (b) such  Asset Sale is for fair  market  value;  provided,
however,  that any consideration not constituting  Replacement  Assets and Crude
Oil and  Natural  Gas  Related  Assets  received  by the  Company  or any of its
Restricted  Subsidiaries  in  connection  with any Asset  Sale  permitted  to be
consummated  under this paragraph shall  constitute Net Cash Proceeds subject to
the provisions of the two immediately preceding paragraphs.

        Notice of each Net Proceeds  Offer will be mailed to the record  Holders
as shown on the register of Holders  within 30 days  following  the Net Proceeds
Offer  Trigger  Date,  with a copy to the  Trustee,  and shall  comply  with the
procedures set forth in the Indenture. Upon receiving notice of the Net Proceeds
Offer,  Holders may elect to tender  their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders  properly tender
Notes with an  aggregate  principal  amount  exceeding  the Net  Proceeds  Offer
Amount,  Notes of tendering Holders will be purchased on a pro rata basis (based
on principal  amounts  tendered).  A Net Proceeds  Offer shall remain open for a
period of 20 Business Days or such longer period as may be required by law.

        The  Company's  ability to repurchase  Notes in a Net Proceeds  Offer is
restricted  by the terms of the New Credit  Facility  and may be  prohibited  or
otherwise limited by the terms of any then existing  borrowing  arrangements and
by the Company's financial resources.

        The Company  will comply with the  requirements  of Rule 14e-1 under the
Exchange Act and any other  securities  laws and  regulations  thereunder to the
extent  such  laws  and  regulations  are  applicable  in  connection  with  the
repurchase  of Notes  pursuant to a Net Proceeds  Offer.  To the extent that the
provisions of any securities laws or regulations  conflict with the "Asset Sale"
provisions  of the  Indenture,  the Company  shall  comply  with the  applicable
securities  laws and  regulations  and shall not be deemed to have  breached its
obligations  under  the  "Asset  Sale"  provisions  of the  Indenture  by virtue
thereof.

        LIMITATION  ON  DIVIDEND  AND  OTHER  PAYMENT   RESTRICTIONS   AFFECTING
RESTRICTED SUBSIDIARIES.  The Company will not, and will not cause or permit any
of its Restricted  Subsidiaries to, directly or indirectly,  create or otherwise
cause or permit to exist or become  effective any  encumbrance or restriction on
the ability of any Restricted  Subsidiary to (a) pay dividends or make any other
distributions on or in respect of its Capital Stock; (b) make loans or advances,
or to pay any Indebtedness or other obligation owed, to the Company or any other
Restricted Subsidiary; (c) guarantee any Indebtedness or any other obligation of
the Company or any Restricted Subsidiary; or (d) transfer any of its property or
assets to the Company or any other Restricted  Subsidiary (each such encumbrance
or  restriction,  a  "Payment  Restriction"),  except for such  encumbrances  or
restrictions  existing  under or by reason  of:  (i)  applicable  law;  (ii) the
Indenture;   (iii)  the  New  Credit  Facility;  (iv)  customary  non-assignment
provisions  of any contract or any lease  governing a leasehold  interest of any
Restricted Subsidiary; (v) any instrument governing Acquired Indebtedness, which
encumbrance or restriction is not applicable to such Restricted  Subsidiary,  or
the properties or assets of such Restricted Subsidiary, other than the Person or
the properties or assets of the Person so acquired;  (vi) agreements existing on
the Issue Date to the extent and in the manner such  agreements are in effect on
the Issue  Date;  (vii)  customary  restrictions  with  respect to a  Restricted
Subsidiary  of the Company  pursuant to an agreement  that has been entered into
for the sale or  disposition  of  Capital  Stock or  assets  of such  Restricted
Subsidiary  to be  consummated  in  accordance  with the terms of the  Indenture
solely in  respect of the assets or  Capital  Stock to be sold or  disposed  of;
(viii) any instrument  governing a Permitted Lien, to the extent and only to the
extent such  instrument  restricts the transfer or other  disposition  of assets
subject to such  Permitted  Lien;  or (ix) an  agreement  governing  Refinancing
Indebtedness incurred to Refinance the Indebtedness issued,  assumed or incurred
pursuant to an agreement  referred to in clause (ii),  (iii), (v) or (vi) above;
provided,   however,  that  the  provisions  relating  to  such  encumbrance  or
restriction contained in any such Refinancing Indebtedness are no less favorable
to the Holders in any material  respect as  determined by the Board of Directors
of the Company in their  reasonable  and good faith judgment than the provisions
relating  to  such  encumbrance  or  restriction  contained  in  the  applicable
agreement referred to in such clause (ii), (iii), (v) or (vi).

        LIMITATION ON PREFERRED  STOCK OF RESTRICTED  SUBSIDIARIES.  The Company
will  not  cause or  permit  any of its  Restricted  Subsidiaries  to issue  any
Preferred  Stock  (other  than to the  Company or to a Wholly  Owned  Restricted
Subsidiary)  or permit  any Person  (other  than the  Company or a Wholly  Owned
Restricted Subsidiary) to own any Preferred Stock of any Restricted Subsidiary.

        Limitation on Liens.  Other than Permitted  Liens, the Company will not,
and will not cause or permit any of its Restricted  Subsidiaries to, directly or
indirectly,  create, incur, assume or permit or suffer to exist any Liens of any
kind  against  or upon any  property  or  assets  of the  Company  or any of its
Restricted  Subsidiaries  (whether owned on the Issue Date or acquired after the
Issue Date) or any proceeds  therefrom,  or assign or otherwise convey any right
to receive income or profits  therefrom unless (a) in the case of Liens securing
Indebtedness that is expressly  subordinate or junior in right of payment to the
Notes or any  Guarantee,  the Notes or such  Guarantee,  as the case may be, are
secured  by a Lien on such  property,  assets  or  proceeds  that is  senior  in
priority  to such  Liens at least to the same  extent as the Notes are senior in
priority  to such  Indebtedness  and (b) in all other  cases,  the Notes and the
Guarantees are equally and ratably secured.

        MERGER,  CONSOLIDATION  AND SALE OF ASSETS.  The Company  will not, in a
single transaction or series of related transactions,  consolidate or merge with
or into any  Person,  or sell,  assign,  transfer,  lease,  convey or  otherwise
dispose  of (or cause or  permit  any  Restricted  Subsidiary  to sell,  assign,
transfer, lease, convey or otherwise dispose of) all or substantially all of the
Company's  assets  (determined on a  consolidated  basis for the Company and its
Restricted Subsidiaries), whether as an entirety or substantially as an entirety
to any Person unless: (a) either (i) the Company or such Restricted  Subsidiary,
as the case may be, shall be the surviving or continuing corporation or (ii) the
Person (if other than the Company)  formed by such  consolidation  or into which
the  Company  is  merged  or the  Person  which  acquires  by sale,  assignment,
transfer,  lease,  conveyance or other  disposition the properties and assets of
the Company and its Restricted  Subsidiaries  substantially  as an entirety (the
"Surviving  Entity") (x) shall be a corporation  organized and validly  existing
under the laws of the  United  States or any state  thereof or the  District  of
Columbia and (y) shall expressly assume, by supplemental  indenture (in form and
substance  satisfactory to the Trustee),  executed and delivered to the Trustee,
the due and punctual payment of the principal of, premium,  if any, and interest
on all of the Notes and the  performance  of every  covenant  of the Notes,  the
Indenture and the Registration Rights Agreement on the part of the Company to be
performed or observed;  (b) immediately  after giving effect to such transaction
and the assumption  contemplated by clause  (a)(ii)(y) above  (including  giving
effect to any Indebtedness  incurred or anticipated to be incurred in connection
with or in respect of such  transaction),  the Company or such Surviving Entity,
as the case may be, (i) shall have a Consolidated  Net Worth equal to or greater
than  the  Consolidated  Net  Worth  of the  Company  immediately  prior to such
transaction  and  (ii)  shall be able to  incur  at  least  $1.00 of  additional
Indebtedness (other than Permitted  Indebtedness)  pursuant to "-- Limitation on
Incurrence  of  Additional  Indebtedness"  above;  (c)  immediately  before  and
immediately   after  giving  effect  to  such  transaction  and  the  assumption
contemplated by clause (a)(ii)(y) above (including,  without limitation,  giving
effect to any  Indebtedness  incurred or anticipated to be incurred and any Lien
granted in  connection  with or in respect  of the  transaction),  no Default or
Event of Default  shall have occurred or be  continuing;  and (d) the Company or
the Surviving Entity, as the case may be, shall have delivered to the Trustee an
officers'  certificate  and an  opinion  of  counsel,  each  stating  that  such
consolidation,  merger, sale, assignment,  transfer,  lease, conveyance or other
disposition and, if a supplemental indenture is required in connection with such
transaction,  such supplemental  indenture comply with the applicable provisions
of the Indenture and that all conditions  precedent in the Indenture relating to
such transaction have been satisfied;  provided,  however, that such counsel may
rely, as to matters of fact, on a certificate or certificates of officers of the
Company.

        For purposes of the foregoing, the transfer (by lease, assignment,  sale
or  otherwise,  in a single  transaction  or series of  transactions)  of all or
substantially  all of the  properties  or  assets  of  one  or  more  Restricted
Subsidiaries the Capital Stock of which  constitutes all or substantially all of
the properties and assets of the Company,  shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.

        Upon any consolidation,  combination or merger or any transfer of all or
substantially all of the assets of the Company in accordance with the foregoing,
in which the Company is not the  continuing  corporation,  the successor  Person
formed by such  consolidation  or into  which the  Company is merged or to which
such conveyance,  lease or transfer is made shall succeed to, and be substituted
for, and may exercise  every right and power of, the Company under the Indenture
and the Notes with the same effect as if such surviving entity had been named as
such.

        Each  Subsidiary  Guarantor  (other than any Subsidiary  Guarantor whose
Guarantee is to be released in  accordance  with the terms of the  Guarantee and
the Indenture in connection with any  transaction  complying with the provisions
of the Indenture  described  under "Merger,  Consolidation  and Sale of Assets")
will not, and the Company will not cause or permit any Subsidiary  Guarantor to,
consolidate  with or merge  with or into any Person  other  than the  Company or
another  Subsidiary  Guarantor  that is a  Wholly  Owned  Restricted  Subsidiary
unless:  (a) the entity formed by or surviving any such  consolidation or merger
(if  other  than  the  Subsidiary  Guarantor)  or to  which  such  sale,  lease,
conveyance or other disposition shall have been made is a corporation  organized
and  existing  under the laws of the United  States or any state  thereof or the
District of Columbia;  (b) such entity  assumes by  execution of a  supplemental
indenture  all  of  the  obligations  of  the  Subsidiary  Guarantor  under  its
Guarantee;  (c) immediately after giving effect to such transaction,  no Default
or Event of Default shall have occurred and be continuing;  and (d)  immediately
after  giving  effect  to such  transaction  and  the  use of any  net  proceeds
therefrom on a pro forma basis,  the Company  could  satisfy the  provisions  of
clause (b) of the first paragraph of this covenant.  Any merger or consolidation
of a Subsidiary  Guarantor with and into the Company (with the Company being the
surviving  entity)  or  another  Subsidiary  Guarantor  that is a  Wholly  Owned
Restricted Subsidiary need only comply with clause (d) of the first paragraph of
this covenant.

        LIMITATIONS ON TRANSACTIONS  WITH AFFILIATES.  (a) The Company will not,
and will not cause or permit any of its Restricted  Subsidiaries to, directly or
indirectly,  enter into,  amend or permit or suffer to exist any  transaction or
series of related  transactions  (including,  without limitation,  the purchase,
sale, lease or exchange of any property, the guaranteeing of any Indebtedness or
the  rendering  of any  service)  with,  or for the  benefit  of,  any of  their
respective  Affiliates  (each  an  "Affiliate  Transaction"),   other  than  (i)
Affiliate  Transactions  permitted under paragraph (b) of this covenant and (ii)
Affiliate  Transactions  that are on terms that are fair and  reasonable  to the
Company or the applicable Restricted Subsidiary and are no less favorable to the
Company or the applicable Restricted Subsidiary than those that might reasonably
have been obtained in a comparable  transaction at such time on an  arm's-length
basis from a Person that is not an Affiliate  of the Company or such  Restricted
Subsidiary.  All Affiliate  Transactions  (and each series of related  Affiliate
Transactions  which are similar or part of a common  plan)  involving  aggregate
payments  or other  property  with a fair market  value in excess of  $1,000,000
shall be approved by the Board of Directors of the Company,  such approval to be
evidenced  by a Board  Resolution  stating  that  such  Board of  Directors  has
determined that such transaction complies with the foregoing provisions.  If the
Company or any Restricted  Subsidiary enters into an Affiliate Transaction (or a
series of related Affiliate Transactions related to a common plan) that involves
an aggregate  fair market  value of more than  $10,000,000,  the Company  shall,
prior to the consummation thereof, obtain a favorable opinion as to the fairness
of such  transaction  or series of related  transactions  to the  Company or the
relevant  Restricted  Subsidiary,  as the case may be, from a financial point of
view, from an Independent Advisor and file the same with the Trustee.

        (b) The  restrictions  set  forth in  clause  (a) shall not apply to (i)
reasonable fees and  compensation  paid to and indemnity  provided on behalf of,
officers,  directors,  employees or consultants of the Company or any Restricted
Subsidiary  as  determined  in good  faith by the Board of  Directors  or senior
management  of the Company or such  Restricted  Subsidiary,  as the case may be;
(ii)  transactions  exclusively  between  or among  the  Company  and any of its
Restricted   Subsidiaries  or  exclusively  between  or  among  such  Restricted
Subsidiaries;  provided,  however,  that  such  transactions  are not  otherwise
prohibited  by  the  Indenture;  (iii)  Restricted  Payments  permitted  by  the
Indenture;  and (iv) the payment of such portion of the CGGS purchase  price, if
any, as shall have been held in escrow to the former shareholders of CGGS.

        LIMITATION ON RESTRICTED AND  UNRESTRICTED  SUBSIDIARIES.  The Indenture
provides  that the Board of  Directors  may,  if no  Default or Event of Default
shall have  occurred and be continuing  or would arise  therefrom,  designate an
Unrestricted Subsidiary to be a Restricted Subsidiary;  provided,  however, that
(i) any such redesignation shall be deemed to be an incurrence as of the date of
such  redesignation  by the  Company  and  its  Restricted  Subsidiaries  of the
Indebtedness  (if  any) of such  redesignated  Subsidiary  for  purposes  of "--
Limitation on Incurrence of  Additional  Indebtedness"  above,  (ii) unless such
redesignated Subsidiary shall not have any Indebtedness outstanding,  other than
Indebtedness which would be Permitted Indebtedness, no such designation shall be
permitted if  immediately  after  giving  effect to such  redesignation  and the
incurrence of any such additional Indebtedness the Company could not incur $1.00
of additional  Indebtedness (other than Permitted  Indebtedness) pursuant to "--
Limitation  on  Incurrence  of  Additional  Indebtedness"  above and (iii)  such
Subsidiary  assumes  by  execution  of  a  supplemental  indenture  all  of  the
obligations of a Subsidiary Guarantor under a Guarantee.

        The Board of  Directors  of the Company also may, if no Default or Event
of Default  shall have  occurred  and be  continuing  or would arise  therefrom,
designate any Restricted Subsidiary to be an Unrestricted Subsidiary if (i) such
designation  is at that  time  permitted  under  "--  Limitation  on  Restricted
Payments" above and (ii)  immediately  after giving effect to such  designation,
the Company could incur $1.00 of additional  Indebtedness  (other than Permitted
Indebtedness)   pursuant  to   "--Limitation   on   Incurrence   of   Additional
Indebtedness"  above.  Any such  designation by the Board of Directors  shall be
evidenced  to the Trustee by the filing with the Trustee of a certified  copy of
the  resolution of the Board of Directors  giving effect to such  designation or
redesignation and an Officers'  Certificate  certifying that such designation or
redesignation  complied  with the  foregoing  conditions  and  setting  forth in
reasonable detail the underlying calculations.  In the event that any Restricted
Subsidiary  is  designated an  Unrestricted  Subsidiary in accordance  with this
covenant, such Restricted Subsidiary's Guarantee will be released.

        The Indenture provides that for purposes of the covenant described under
"--  Limitation on Restricted  Payments"  above,  (i) an  "Investment"  shall be
deemed to have been made at the time any Restricted  Subsidiary is designated as
an Unrestricted  Subsidiary in an amount  (proportionate to the Company's equity
interest  in  such  Subsidiary)  equal  to the  net  worth  of  such  Restricted
Subsidiary  at the time that such  Restricted  Subsidiary  is  designated  as an
Unrestricted Subsidiary; (ii) at any date the aggregate amount of all Restricted
Payments made as  Investments  since the Issue Date shall exclude and be reduced
by an amount (proportionate to the Company's equity interest in such Subsidiary)
equal to the net  worth of any  Unrestricted  Subsidiary  at the time  that such
Unrestricted Subsidiary is designated a Restricted Subsidiary, not to exceed, in
the case of any such redesignation of an Unrestricted Subsidiary as a Restricted
Subsidiary,  the amount of  Investments  previously  made by the Company and its
Restricted  Subsidiaries in such  Unrestricted  Subsidiary (in each case (i) and
(ii) "net worth" to be calculated based upon the fair market value of the assets
of such Subsidiary as of any such date of  designation);  and (iii) any property
transferred to or from an  Unrestricted  Subsidiary  shall be valued at its fair
market value at the time of such transfer.

        The Indenture provides that notwithstanding the foregoing,  the Board of
Directors may not designate any Subsidiary of the Company to be an  Unrestricted
Subsidiary  if,  after  such  designation,  (a) the  Company  or any  Restricted
Subsidiary (i) provides credit support for, or a guarantee of, any  Indebtedness
of  such  Subsidiary   (including  any  undertaking,   agreement  or  instrument
evidencing such  Indebtedness) or (ii) is directly or indirectly  liable for any
Indebtedness  of such  Subsidiary or (b) such  Subsidiary owns any Capital Stock
of, or owns or holds any Lien on any  property  of,  any  Restricted  Subsidiary
which is not a Subsidiary of the Subsidiary to be so designated.

        The  Indenture  provides that  Subsidiaries  of the Company that are not
designated by the Board of Directors as Restricted or Unrestricted  Subsidiaries
will be deemed to be Restricted Subsidiaries.  Notwithstanding any provisions of
this  covenant,   all  Subsidiaries  of  an  Unrestricted   Subsidiary  will  be
Unrestricted Subsidiaries.

        ADDITIONAL  SUBSIDIARY  GUARANTEES.   If  the  Company  or  any  of  its
Restricted   Subsidiaries  transfers  or  causes  to  be  transferred,   in  one
transaction or a series of related transactions,  any property to any Restricted
Subsidiary that is not a Subsidiary  Guarantor,  or if the Company or any of its
Restricted  Subsidiaries shall organize,  acquire or otherwise invest in or hold
an Investment in another Restricted  Subsidiary having total consolidated assets
with a book value in excess of $500,000 that is not a Subsidiary Guarantor, then
such transferee or acquired or other Restricted Subsidiary shall (a) execute and
deliver to the Trustee a supplemental indenture in form reasonably  satisfactory
to  the   Trustee   pursuant   to  which  such   Restricted   Subsidiary   shall
unconditionally  guarantee all of the Company's  obligations under the Notes and
the  Indenture  on the terms set forth in the  Indenture  and (b) deliver to the
Trustee an opinion of counsel  that such  supplemental  indenture  has been duly
authorized, executed and delivered by such Restricted Subsidiary and constitutes
a  legal,  valid,   binding  and  enforceable   obligation  of  such  Restricted
Subsidiary.  Thereafter,  such  Restricted  Subsidiary  shall  be  a  Subsidiary
Guarantor for all purposes of the Indenture.

        LIMITATION  ON CONDUCT OF  BUSINESS.  The Company will not, and will not
permit  any of its  Restricted  Subsidiaries  to,  engage in the  conduct of any
business other than the Crude Oil and Natural Gas Business.

        REPORTS TO HOLDERS.  The Company will  deliver to the Trustee  within 15
days after the filing of the same with the  Commission,  copies of the quarterly
and annual reports and of the information,  documents and other reports, if any,
which the Company is required to file with the Commission pursuant to Section 13
or 15(d) of the  Exchange  Act.  Notwithstanding  that  the  Company  may not be
subject to the  reporting  requirements  of Section 13 or 15(d) of the  Exchange
Act, the Company will file with the  Commission,  to the extent  permitted,  and
provide the Trustee and Holders with such annual  reports and such  information,
documents and other  reports  specified in Sections 13 and 15(d) of the Exchange
Act.  The Company  will also comply with the other  provisions  of 314(a) of the
TIA.



<PAGE>


EVENTS OF DEFAULT

        The  following  events  are  defined  in the  Indenture  as  "Events  of
Default":

        (a) the failure to pay interest  (including any Additional  Interest) on
any Notes when the same becomes due and payable and the default  continues for a
period of 30 days;

        (b) the failure to pay the principal on any Notes,  when such  principal
becomes due and payable,  at maturity,  upon redemption or otherwise  (including
the failure to make a payment to purchase Notes tendered pursuant to a Change of
Control Offer or a Net Proceeds Offer);

        (c) a default in the  observance or performance of any other covenant or
agreement  contained in the Indenture which default continues for a period of 30
days after either Issuer  receives  written  notice  specifying the default (and
demanding  that such default be remedied)  from the Trustee or the Holders of at
least 25% of the outstanding  principal  amount of the Notes (except in the case
of a default with respect to  observance or  performance  of any of the terms or
provisions  of  "--  Change  of  Control"  or  "Certain   Covenants  --  Merger,
Consolidation  and Sale of Assets" or "--  Limitation on Asset Sales" which will
constitute  an Event of Default  with such notice  requirement  but without such
passage of time requirement);

        (d) a default  under any mortgage,  indenture or instrument  under which
there  may  be  issued  or by  which  there  may be  secured  or  evidenced  any
Indebtedness  of the Company or of any Restricted  Subsidiary (or the payment of
which is guaranteed by the Issuers or any Restricted  Subsidiary),  whether such
Indebtedness now exists or is created after the Issue Date, which default (i) is
caused by a failure to pay principal of or premium,  if any, or interest on such
Indebtedness  after any applicable grace period provided in such Indebtedness (a
"payment  default") or (ii)  results in the  acceleration  of such  Indebtedness
prior to its express  maturity and, in each case,  the  principal  amount of any
such  Indebtedness,  together  with  the  principal  amount  of any  other  such
Indebtedness  under  which there has been a payment  default or the  maturity of
which has been so accelerated, aggregates at least $5,000,000;

        (e) one or more judgments in an aggregate amount in excess of $5,000,000
(unless covered by insurance by a reputable  insurer as to which the insurer has
acknowledged  coverage)  shall have been rendered  against the Company or any of
its Restricted  Subsidiaries and such judgments remain undischarged,  unvacated,
unpaid or  unstayed  for a period of 60 days after such  judgment  or  judgments
become final and non-appealable;

        (f) certain  events of  bankruptcy  affecting the Company or any of its
Subsidiaries; or

        (g) any of the Guarantees cease to be in full force and effect or any of
the Guarantees are declared to be null and void or invalid and  unenforceable or
any of the Subsidiary  Guarantors  denies or disaffirms its liability  under its
Guarantees  (other  than by reason  of  release  of a  Subsidiary  Guarantor  in
accordance with the terms of the Indenture).

        The Indenture provides that, if an Event of Default (other than an Event
of Default  specified  in clause (f) above) shall occur and be  continuing,  the
Trustee or the Holders of at least 25% in principal amount of outstanding  Notes
may declare the principal of,  premium,  if any, and accrued and unpaid interest
on all the Notes to be due and  payable by notice in writing to the  Issuers and
the  Trustee  specifying  the  Event  of  Default  and that it is a  "notice  of
acceleration",  and the same shall become  immediately  due and  payable.  If an
Event of Default  specified in clause (f) above occurs and is  continuing,  then
all unpaid principal of, and premium, if any, and accrued and unpaid interest on
all of the outstanding  Notes shall ipso facto become and be immediately due and
payable  without any  declaration or other act on the part of the Trustee or any
Holder.

        The  Indenture  provides  that,  at any  time  after  a  declaration  of
acceleration with respect to the Notes as described in the preceding  paragraph,
the  Holders of a majority  in  principal  amount of the Notes may  rescind  and
cancel such  declaration and its  consequences  (a) if the rescission  would not
conflict with any judgment or decree, (b) if all existing Events of Default have
been cured or waived except  nonpayment of principal or interest that has become
due solely because of such  acceleration,  (c) to the extent the payment of such
interest is lawful,  interest on overdue  installments  of interest  and overdue
principal,   which  has  become  due  otherwise  than  by  such  declaration  of
acceleration,  has been  paid,  (d) if the  Issuers  have paid the  Trustee  its
reasonable   compensation   and   reimbursed   the  Trustee  for  its  expenses,
disbursements  and  advances  and (e) in the  event of the cure or  waiver of an
Event of  Default of the type  described  in clause  (f) of the  description  of
Events  of  Default  above,   the  Trustee  shall  have  received  an  officers'
certificate  and an opinion of counsel that such Event of Default has been cured
or waived; provided, however, that such counsel may rely, as to matters of fact,
on a certificate or certificates of officers of the Company.  No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

        The Indenture  provides  that, at any time prior to the  declaration  of
acceleration of the Notes,  the Holders of a majority in principal amount of the
Notes may waive any existing  Default or Event of Default  under the  Indenture,
and its  consequences,  except a default in the payment of the  principal  of or
interest on any Notes.

        The Indenture  provides  that,  Holders of the Notes may not enforce the
Indenture  or the Notes except as provided in the  Indenture  and under the TIA.
During the existence of an Event of Default, the Trustee is required to exercise
such rights and powers  vested in it under the Indenture and use the same degree
of care and skill in its exercise thereof as a prudent man would exercise or use
under the  circumstances  in the  conduct  of his own  affairs.  Subject  to the
provisions  of the Indenture  relating to the duties of the Trustee,  whether or
not an Event of Default shall occur and be  continuing,  the Trustee is under no
obligation  to exercise any of its rights or powers  under the  Indenture at the
request,  order or  direction  of any of the  Holders,  unless such Holders have
offered to the Trustee  reasonable  indemnity.  Subject to all provisions of the
Indenture and applicable  law, the Holders of a majority in aggregate  principal
amount of the then outstanding  Notes have the right to direct the time,  method
and place of conducting any  proceeding for any remedy  available to the Trustee
or exercising any trust or power conferred on the Trustee.

        Under the  Indenture,  the Issuers are  required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge of
any Default or Event of Default  (provided that such officers shall provide such
certification at least annually whether or not they know of any Default or Event
of Default) that has occurred and, if applicable, describe such Default or Event
of Default and the status thereof.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

        The Issuers  may, at their  option and at any time,  elect to have their
obligations  and the  corresponding  obligations  of the  Subsidiary  Guarantors
discharged  with respect to the  outstanding  Notes ("Legal  Defeasance").  Such
Legal  Defeasance  means  that the  Issuers  shall be  deemed  to have  paid and
discharged the entire  indebtedness  represented by the outstanding  Notes,  and
satisfied all of their obligations with respect to the Notes, except for (a) the
rights of Holders to receive  payments in respect of the principal of,  premium,
if any, and  interest on the Notes when such  payments are due, (b) the Issuers'
obligations  with  respect  to the Notes  concerning  issuing  temporary  Notes,
registration  of  Notes,  mutilated,  destroyed,  lost or  stolen  Notes and the
maintenance of an office or agency for payments,  (c) the rights, powers, trust,
duties and immunities of the Trustee and the Issuers'  obligations in connection
therewith and (d) the Legal Defeasance provisions of the Indenture. In addition,
the Issuers may, at their option and at any time,  elect to have the obligations
of the Issuers released with respect to certain  covenants that are described in
the Indenture ("Covenant Defeasance") and thereafter any omission to comply with
such obligations shall not constitute a Default or Event of Default with respect
to the Notes.  In the event Covenant  Defeasance  occurs,  certain events (other
than  non-payment,  bankruptcy,  receivership,   reorganization  and  insolvency
events)  described  under "-- Events of Default"  will no longer  constitute  an
Event of Default with respect to the Notes.

        In order to exercise either Legal Defeasance or Covenant Defeasance, (a)
the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit
of the  Holders  cash in  United  States  dollars,  non-callable  United  States
government  obligations,  or a combination  thereof,  in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest on the Notes
on the stated date for payment thereof or on the applicable  redemption date, as
the case may be; (b) in the case of Legal  Defeasance,  the  Issuers  shall have
delivered to the Trustee an opinion of counsel in the United  States  reasonably
acceptable to the Trustee confirming that (i) the Issuers have received from, or
there has been published by, the Internal Revenue Service a ruling or (ii) since
the date of the  Indenture,  there has been a change in the  applicable  federal
income  tax law,  in either  case to the effect  that,  and based  thereon  such
opinion of counsel shall confirm  that,  the Holders will not recognize  income,
gain or  loss  for  federal  income  tax  purposes  as a  result  of such  Legal
Defeasance and will be subject to federal income tax on the same amounts, in the
same  manner  and at the same  times as would  have been the case if such  Legal
Defeasance had not occurred, (c) in the case of Covenant Defeasance, the Issuers
shall have  delivered to the Trustee an opinion of counsel in the United  States
reasonably  acceptable  to the  Trustee  confirming  that the  Holders  will not
recognize  income,  gain or loss for federal  income tax purposes as a result of
such Covenant  Defeasance  and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Covenant  Defeasance  had not occurred;  (d) no Default or Event of Default
shall have  occurred and be continuing on the date of such deposit or insofar as
Events of Default from  bankruptcy or insolvency  events are  concerned,  at any
time in the period  ending on the 91st day after the date of  deposit;  (e) such
Legal  Defeasance  or  Covenant  Defeasance  shall  not  result  in a breach  or
violation of, or constitute a default under the Indenture or any other agreement
or instrument to which the Company or any of its  Restricted  Subsidiaries  is a
party or by which the Company or any of its  Restricted  Subsidiaries  is bound;
(f) the Issuers  shall have  delivered to the Trustee an  officers'  certificate
stating  that  the  deposit  was not made by the  Issuers  with  the  intent  of
preferring  the Holders over any other  creditors  of either  Issuer or with the
intent of defeating,  hindering,  delaying or defrauding any other  creditors of
the Issuers or others;  (g) the Issuers  shall have  delivered to the Trustee an
officers'  certificate  and  an  opinion  of  counsel,  each  stating  that  all
conditions  precedent  provided for or relating to the Legal  Defeasance  or the
Covenant  Defeasance,  as the case may be, have been  complied  with;  provided,
however,  that such counsel may rely, as to matters of fact, on a certificate or
certificates of officers of the Company; (h) the Issuers shall have delivered to
the  Trustee  an  opinion  of  counsel  to the  effect  that  after the 91st day
following the deposit,  the trust funds will not be subject to the effect of any
applicable  bankruptcy,  insolvency,  reorganization  or similar laws  affecting
creditors' rights generally;  provided,  however, that such counsel may rely, as
to matters of fact, on a certificate or certificates of officers of the Issuers;
and (i) certain other customary conditions precedent are satisfied.

SATISFACTION AND DISCHARGE

        The Indenture  will be discharged and will cease to be of further effect
(except as to surviving  rights of  registration  of transfer or exchange of the
Notes, as expressly  provided for in the Indenture) as to all outstanding  Notes
when (a) either  (i) all the  Notes,  theretofore  authenticated  and  delivered
(except  lost,  stolen or destroyed  Notes which have been  replaced or paid and
Notes for  whose  payment  money  has  theretofore  been  deposited  in trust or
segregated and held in trust by the Issuers and thereafter repaid to the Issuers
or  discharged  from  such  trust)  have  been  delivered  to  the  Trustee  for
cancellation  or (ii) all Notes not  theretofore  delivered  to the  Trustee for
cancellation  have  become due and  payable  and the  Issuers  have  irrevocably
deposited  or  caused  to be  deposited  with the  Trustee  funds  in an  amount
sufficient  to pay and  discharge  the  entire  Indebtedness  on the  Notes  not
theretofore  delivered  to the  Trustee  for  cancellation,  for  principal  of,
premium,  if any, and interest on the Notes to the date of deposit together with
irrevocable  instructions  from the Issuers  directing the Trustee to apply such
funds to the payment thereof at maturity or redemption,  as the case may be; (b)
the Issuers have paid all other sums payable under the Indenture by the Issuers;
and (c) the Issuers have delivered to the Trustee an officers'  certificate  and
an opinion of counsel stating that all conditions  precedent under the Indenture
relating to the  satisfaction  and discharge of the Indenture have been complied
with; provided, however, that such counsel may rely, as to matters of fact, on a
certificate or certificates of officers of the Issuers.

MODIFICATION OF THE INDENTURE

        From  time to time,  the  Issuers,  the  Subsidiary  Guarantors  and the
Trustee, without the consent of the Holders, may amend the Indenture for certain
specified purposes, including curing ambiguities, defects or inconsistencies, to
comply with any  requirements  of the  Commission in order to effect or maintain
the  qualification  of the  Indenture  under the TIA or to make any change  that
would provide any  additional  benefit or rights to the Holders or that does not
adversely  affect the rights of any Holder.  In formulating  its opinion on such
matters,  the  Trustee  will be  entitled  to rely on such  evidence as it deems
appropriate,  including,  without  limitation,  solely on an opinion of counsel;
provided,  however, that in delivering such opinion of counsel, such counsel may
rely, as to matters of fact, on a certificate or certificates of officers of the
Company.  Other  modifications  and amendments of the Indenture may be made with
the  consent  of the  Holders  of a  majority  in  principal  amount of the then
outstanding Notes issued under the Indenture,  except that,  without the consent
of each Holder  affected  thereby,  no  amendment  may: (a) reduce the amount of
Notes whose  Holders  must  consent to an  amendment;  (b) reduce the rate of or
change  or have  the  effect  of  changing  the time for  payment  of  interest,
including  defaulted  interest,  on any Notes;  (c) reduce the  principal  of or
change or have the effect of changing the fixed maturity of any Notes, or change
the date on which any Notes may be  subject  to  redemption  or  repurchase,  or
reduce the redemption or repurchase  price therefor;  (d) make any Notes payable
in money other than that stated in the Notes;  (e) make any change in provisions
of the  Indenture  protecting  the right of each  Holder to  receive  payment of
principal  of and  interest on such Note on or after the due date  thereof or to
bring suit to enforce  such  payment,  or  permitting  Holders of a majority  in
principal  amount of Notes to waive  Defaults or Events of  Default;  (f) amend,
change or modify in any material  respect the  obligation of the Issuers to make
and  consummate a Change of Control Offer in the event of a Change of Control or
make and consummate a Net Proceeds Offer with respect to any Asset Sale that has
been  consummated or modify any of the  provisions or  definitions  with respect
thereto;  (g) modify or change any  provision  of the  Indenture  or the related
definitions  affecting  ranking of the Notes or any  Guarantee in a manner which
adversely affects the Holders; or (h) release any Subsidiary  Guarantor from any
of its  obligations  under its  Guarantee  or the  Indenture  otherwise  than in
accordance with the terms of the Indenture.

GOVERNING LAW

        The Indenture provides that the Indenture,  the Notes and the Guarantees
will be governed by, and construed in accordance  with, the laws of the State of
New York but without giving effect to applicable  principles of conflicts of law
to the extent that the application of the law of another  jurisdiction  would be
required thereby.

THE TRUSTEE

        The Indenture  provides that,  except during the continuance of an Event
of Default,  the Trustee will perform only such duties as are  specifically  set
forth in the Indenture. During the existence of an Event of Default, the Trustee
will exercise such rights and powers vested in it by the Indenture,  and use the
same degree of care and skill in its exercise as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

        The Indenture and the provisions of the TIA contain certain  limitations
on the rights of the  Trustee,  should it become a creditor  of the Issuers or a
Subsidiary  Guarantor,  to obtain  payments  of claims  in  certain  cases or to
realize on certain property received in respect of any such claim as security or
otherwise.  Subject to the TIA, the Trustee will be permitted to engage in other
transactions;  provided,  however,  that if the Trustee acquires any conflicting
interest as described in the TIA, it must eliminate such conflict or resign.

CERTAIN DEFINITIONS

        Set forth below is a summary of certain of the defined terms used in the

Subsidiaries  (and the  application of the proceeds  thereof) giving rise to the
need to  make  such  calculation  and  any  incurrence  or  repayment  of  other
Indebtedness  (and the  application  of the  proceeds  thereof),  other than the
incurrence or repayment of  indebtedness  in the ordinary course of business for
working  capital  purposes  pursuant to working  capital  facilities,  occurring
during the Four Quarter Period or at any time  subsequent to the last day of the
Four  Quarter  Period  and on or  prior  to the  Transaction  Date,  as if  such
incurrence or repayment, as the case may be (and the application of the proceeds
thereof), occurred on the first day of the Four Quarter Period and (b) any Asset
Sales  or  Asset  Acquisitions   (including,   without  limitation,   any  Asset

incurred on the  Transaction  Date may  optionally  be determined at an interest
rate based upon a factor of a prime or similar  rate, a  eurocurrency  interbank

Transaction  Date will be deemed to have been in effect  during the Four Quarter
Period;  (iii)   notwithstanding   clauses  (i)  and  (ii)  above,  interest  on
Indebtedness  determined on a fluctuating  basis, to the extent such interest is
covered by agreements relating to Interest Swap Obligations,  shall be deemed to
accrue at the rate per annum  resulting  after giving effect to the operation of

period of 30 consecutive  Trading Days during the period from and after November
17, 1996 to and including November 17, 1997.

        In the event that Abraxas  determines that no shares of the Common Stock
are issuable with respect to the CVRs to the CVR Holders,  Abraxas shall give to
the CVR Holders notice of such determination. Upon making such determination and
absent manifest error, the CVRs shall terminate and become null and void and the
CVR Holders shall have no further  rights with respect  thereto.  The failure to
give such  notice or any defect  therein  shall not affect the  validity of such
determination.

        ANTIDILUTION.  In the event  Abraxas  shall in any manner  subdivide (by
stock split,  stock dividend or otherwise) or combine (by reverse stock split or
otherwise) the number of outstanding  shares of the Common Stock,  Abraxas shall
similarly  subdivide  or  combine  the CVRs and shall  approximately  adjust the
Target Price.  Whenever  such an adjustment is made,  Abraxas shall (i) promptly
prepare a certificate setting forth such adjustment and a brief statement of the
facts accounting for such adjustment, (ii) promptly file with First Union a copy
of such  certificate  and (iii) mail a brief summary thereof to each CVR Holder.
First Union shall be fully  protected in relying on any such  certificate and on
any adjustment therein contained. Such adjustment absent manifest error shall be
final  and  binding  on  Abraxas  and  the CVR  Holders.  Each  outstanding  CVR
Certificate shall  thenceforth  represent that number of adjusted CVRs necessary
to reflect such  subdivision  or  combination  and reflect the  adjusted  Target
Price.

        CONSOLIDATION,  MERGER AND SALE OF ASSETS.  The CVR  Agreement  provides
that Abraxas may,  without the consent of the holders of any of the  outstanding
CVRs,  consolidate  with or merge into any other  entity or convey,  transfer or
lease its  properties  and assets  substantially  as an  entirety to any entity,
provided  that (i) the  Surviving  Person (as defined  below)  assumes  Abraxas'
obligations  under the CVRs and the CVR Agreement  and (ii) Abraxas  delivers to
First Union an officer's  certificate  regarding  compliance with the foregoing.
For the purposes  hereof,  "convey,  transfer or lease its properties and assets
substantially  as an entirety" shall mean properties and assets  contributing in
the aggregate of at least 80% of Abraxas' total revenues as reported in Abraxas'
last available  periodic  financial report (quarterly or annual, as the case may
be) filed with the Commission.

        In the event that Abraxas were merged out of  existence,  liquidated  or
subject to some other event  resulting  in the lack of any market for the Common
Stock  (each,  a  "Transaction"),  the  holders of the CVRs would be entitled to
receive  securities of the  Surviving  Person or such other  consideration  that
holders of shares of the Common  Stock  received  in such a  Transaction  on the
basis described herein. In the event of a Transaction in which the consideration
received by the  stockholders  of Abraxas were shares of capital  stock or other
securities  of the  Surviving  Person,  the CVRs  would  mature on the  Extended
Maturity  Date,  the Target Price would be adjusted by dividing the Target Price
by the  Conversion  Ratio (as  defined  below) and the holders of the CVRs would
receive on the Extended Maturity Date a number of shares of the capital stock or
other  securities of the Surviving Person equal to (a) the Adjusted Target Price
(as defined  below) minus the Adjusted  Current  Market Value (as defined below)
divided by (b) the Adjusted Current Market Value; provided, however, in no event
shall the  Surviving  Person (a) be  required to issue a number of shares of its
capital stock or other securities greater than 1.5 times the Conversion Ratio at
the Extended  Maturity  Date and (b) issue shares of its capital  stock or other
securities which are not publicly traded to the holders of the CVRs for any CVRs
held by them. In the event that the shares of capital stock or other  securities
of the Surviving  Person to be issued in a Transaction are not publicly  traded,
the consideration to be received by the holders of the CVRs for any CVRs held by
them shall be cash calculated in the manner described in the following sentence.
In the event of a  Transaction  in which the  holders of Abraxas'  Common  Stock
received  cash, the holders of the CVRs would receive cash in an amount equal to
the Adjusted Target Price minus the cash received by the stockholders of Abraxas
for one share of the Common Stock on the effective  date of such a  Transaction;
provided,  however  that the holders of the CVRs would not receive  greater than
$7.50 per CVR in cash from and after  November  17,  1996 to and  including  the
Extended Maturity Date.

WARRANTS

        Abraxas has warrants  ("Warrants")  outstanding to purchase an aggregate
of 437,500 shares of Common Stock. Associated Energy Managers, Inc. ("AEM"), has
Warrants to  purchase  13,500  shares at an  exercise  price of $7.00 per share.
First  Union has  Warrants  to  purchase  424,000  shares of Common  Stock at an
exercise price of $9.79 per share.  These Warrants were issued to First Union in
connection  with  Abraxas'  credit  agreement.  First Union and AEM have certain
registration  rights with respect to shares of the Common Stock issued  pursuant
to the exercise of such Warrants. See " -- Registration Rights."

        All outstanding  Warrants contain  provisions that protect AEM and First
Union  against  dilution  by  adjusting  the  price at which  the  Warrants  are
exercisable  and the number of shares of the Common Stock issuable upon exercise
thereof  upon the  occurrence  of  certain  events,  including  payment of stock
dividends and distributions, stock splits, recapitalizations, reclassifications,
mergers,  consolidations  or the  issuance  or sale of Common  Stock or options,
rights or securities convertible into shares of the Common Stock, in the case of
AEM, at less than the current market price or, in the case of First Union,  at a
price less than the greater of the current market price or the exercise price. A
holder of Warrants has no rights as a stockholder  of Abraxas until the Warrants
are exercised.  All Warrants are currently exercisable,  although none have been
exercised as of the date hereof.

REGISTRATION RIGHTS

        The shares of the Common  Stock to be  received  by AEM and First  Union
upon  exercise of Warrants and any shares of the Common Stock owned by Endowment
Energy  Partners,  L.P.  ("EEP")  and  Endowment  Energy  Partners  II,  Limited
Partnership  ("EEP II") are  entitled  to  certain  rights  with  respect to the
registration of such shares under the Securities Act.

        Under the terms of the  Registration  Rights  Agreement with EEP and EEP
II, in the event that  Abraxas  proposes  to  register  any shares of the Common
Stock or securities  convertible  into Common Stock under the Securities Act for
its own account, except in certain circumstances, EEP and EEP II are entitled to
unlimited Piggyback  Registrations,  subject to the right of the underwriters of
any such offering to limit the number of shares  included in such  registration.
Abraxas  has  agreed  to  pay  all  expenses  in  connection  with  a  Piggyback
Registration  except for underwriting  discounts and selling  commissions  which
shall be borne by EEP and/or EEP II with  respect to shares of the Common  Stock
owned by EEP and EEP II other than the 211,500  shares of Common Stock  acquired
by EEP and EEP II through the exercise of the Warrants formerly owned by EEP and
EEP II ("Warrant  Shares").  EEP and EEP II have the additional right to require
Abraxas  to effect  one Demand  Registration  of all shares of the Common  Stock
(other than Warrant Shares) in the aggregate at any time and Abraxas is required
to effect such  registration,  subject to certain  conditions  and  limitations.
Abraxas is required to bear the  expenses  of a Demand  Registration  except for
underwriting  discounts  and  selling  commissions  which  shall be borne by EEP
and/or  EEP II with  respect to shares of Common  Stock  owned by EEP and EEP II
other than Warrant Shares. Abraxas has agreed to customary indemnities including
an agreement to indemnify, subject to certain limited exceptions, EEP and EEP II
in connection with a Demand Registration and a Piggyback Registration.

        Under  the  terms  of its  Warrants,  AEM has  the  right  to  unlimited
Piggyback  Registrations.   EEP  and  EEP  II  have  the  right  to  one  Demand
Registration  in the aggregate at any time after December 20, 1995 and unlimited
Piggyback  Registrations  with respect to Warrant Shares.  Abraxas has agreed to
pay all expenses in connection  with Piggyback  Registrations  by AEM and by EEP
and EEP II with respect to Warrant Shares and to share expenses equally with EEP
and EEP II with respect to Warrant Shares  registered in a Demand  Registration;
provided,  however, all underwriting  discounts and selling commissions shall be
borne by EEP, EEP II or AEM, as the case may be.

        Under the terms of its Warrants, First Union has the right to two Demand
Registrations  and, subject to the rights to Piggyback  Registration of EEP, EEP
II and AEM,  unlimited  Piggyback  Registrations.  Abraxas will pay all expenses
incurred  in  connection  with any such  registration  other  than  underwriting
discounts and selling  commissions which shall be borne by First Union.  Abraxas
has also agreed to customary  indemnities,  including an agreement to indemnify,
subject  to  certain  limitations,  First  Union  in  connection  with a  Demand
Registration and a Piggyback Registration.


ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION AND
BYLAWS

        Abraxas'  Articles of Incorporation  and Bylaws provide for the Board of
Directors  to be divided  into  three  classes of  directors  serving  staggered
three-year terms. As a result, approximately one-third of the Board of Directors
will be elected each year. The Articles of Incorporation and Bylaws provide that
the Board of Directors  will consist of not less than three nor more than twelve
members,  with  the  exact  number  to be  determined  from  time to time by the
affirmative  vote of a  majority  of  directors  then in  office.  The  Board of
Directors,  and not the stockholders,  has the authority to determine the number
of  directors,  and  could  prevent  any  stockholder  from  obtaining  majority
representation  on  Abraxas'  Board  of  Directors  by  enlarging  the  Board of
Directors  and by  filling  the new  directorships  with the  stockholder's  own
nominees.  In addition,  directors may be removed by the  stockholders  only for
cause.

        The Articles of  Incorporation  and Bylaws provide that special meetings
of stockholders of Abraxas may be called only by the Chairman of the Board,  the
President or a majority of the members of the Board of Directors. This provision
may make it more difficult for stockholders to take actions opposed by the Board
of Directors.

        The  Articles  of  Incorporation  and  Bylaws  provide  that any  action
required  to be taken or which may be taken by holders  of Common  Stock must be
effected at a duly called annual or special meeting of such holders, and may not
be taken by any written consent of such stockholders.  These provisions may have
the effect of delaying  consideration  of a stockholder  proposal until the next
annual  meeting  unless a special  meeting  is called by the  persons  set forth
above.  The provisions of the Articles of Incorporation  and Bylaws  prohibiting
stockholder action by written consent could prevent the holders of a majority of
the voting  power of Abraxas  from using the written  consent  procedure to take
stockholder  action  and  taking  action  by  consent  without  giving  all  the
stockholders of Abraxas entitled to vote on a proposed action the opportunity to
participate in determining such proposed action.

STOCKHOLDER RIGHTS PLAN

        On  November  17,  1994,  the Board of  Directors  of Abraxas  adopted a
stockholder rights plan (the "Rights Plan"). Under the terms of the Rights Plan,
the Board of  Directors  of  Abraxas  declared a  dividend  of one common  share
purchase  right  ("Right")  on each share of the  Common  Stock  outstanding  on
November 17, 1994. Each Right entitles the holder thereof to buy one-half of one
share of  Common  Stock at an  exercise  price  of $40 per  share  ($20 per half
share), subject to adjustment.

        The Rights are not exercisable until the occurrence of specified events.
Upon the  occurrence of such an event (which  events are  generally  those which
would signify the commencement of a hostile bid to acquire Abraxas),  the Rights
then become exercisable (unless redeemed by the Board of Directors) for a number
of shares of Common Stock having a market value of four times the exercise price
of the Right. If the acquiror were to conclude the  acquisition of Abraxas,  the
Rights  would then become  exercisable  for shares of the  controlling/surviving
corporation  having a value of four times the exercise  price of the Rights.  If
the Rights were exercised at any time,  significant  dilution would result, thus
making the  acquisition  prohibitively  expensive for the acquiror.  In order to
encourage a bidder to  negotiate  with the Board of  Directors,  the Rights Plan
provides that the Rights may be redeemed under  prescribed  circumstances by the
Board of Directors.

        The Rights are not  intended  to prevent a takeover  of Abraxas and will
not  interfere  with any tender  offer or business  combination  approved by the
Board of Directors.  The Rights Plan is intended to protect the  stockholders in
the event of (a) an unsolicited offer to acquire Abraxas,  including offers that
do not treat all stockholders equally, (b) the acquisition in the open market of
shares  constituting  control  of  Abraxas  without  offering  fair value to all
stockholders  and (c) other  coercive  takeover  tactics  which could impair the
Board's ability to fully represent the interests of the stockholders.

ANTI-TAKEOVER STATUTES

        The Nevada GCL contains two provisions,  described below as "Combination
Provisions"  and the  "Control  Share  Act,"  that may make more  difficult  the
accomplishment  of  unsolicited  or hostile  attempts  to  acquire  control of a
corporation through certain types of transactions.

RESTRICTIONS ON CERTAIN  COMBINATIONS  BETWEEN NEVADA RESIDENT  CORPORATIONS AND
INTERESTED STOCKHOLDERS

        The  Nevada  GCL   includes   certain   provisions   (the   "Combination
Provisions")  prohibiting certain  "combinations"  (generally defined to include
certain  mergers,  disposition  of assets  transactions,  and share  issuance or
transfer   transactions)   between  a  resident  domestic   corporation  and  an
"interested stockholder" (generally defined to be the beneficial owner of 10% or
more of the voting power of the outstanding  shares of the corporation),  except
those  combinations  which are  approved  by the board of  directors  before the
interested stockholder first obtained a 10% interest in the corporation's stock.
There are additional exceptions to the prohibition,  which apply to combinations
if they occur more than three years after the interested  stockholder's  date of
acquiring shares. The Combination Provisions apply unless the corporation elects
against  their  application  in its  original  articles of  incorporation  or an
amendment  thereto,  or in its bylaws.  Abraxas'  Articles of Incorporation  and
Bylaws do not currently contain a provision rendering the Combination Provisions
inapplicable.

NEVADA CONTROL SHARE ACT

        Nevada's Control Share Acquisition Act (the "Control Share Act") imposes
procedural hurdles on and curtails greenmail practices of corporate raiders. The
Control  Share Act  temporarily  disenfranchises  the voting  power of  "control
shares" of a person or group  ("Acquiring  Person")  purchasing  a  "controlling
interest" in an "issuing  corporation" (as defined in the Nevada GCL) not opting
out of the Control  Share Act. In this regard,  the Control Share Act will apply
to an "issuing  corporation" unless, before an acquisition is made, the articles
of  incorporation or bylaws in effect on the tenth day following the acquisition
of a controlling interest provide that it is inapplicable.  Abraxas' Articles of
Incorporation  and Bylaws do not  currently  contain a provision  rendering  the
Control Share Act inapplicable.

        Under the Control Share Act, an "issuing  corporation"  is a corporation
organized in Nevada which has 200 or more stockholders, at least 100 of whom are
stockholders  of  record  (which  for  this  purpose  includes   registered  and
beneficial  owners) and  residents of Nevada,  and which does business in Nevada
directly or through an affiliated company.  The status of Abraxas at the time of
the occurrence of a transaction governed by the Control Share Act (assuming that
Abraxas'  Articles of  Incorporation or Bylaws have not theretofore been amended
to include an opting out provision)  would  determine  whether the Control Share
Act is applicable.

        The Control  Share Act  requires  an  Acquiring  Person to take  certain
procedural steps before he or it can obtain the full voting power of the control
shares. "Control shares" are the shares of a corporation (1) acquired or offered
to be acquired  which will  enable the  Acquiring  Person to own a  "controlling
interest," and (2) acquired  within 90 days  immediately  preceding that date. A
"controlling  interest" is defined as the ownership of shares which would enable
the Acquiring  Person to exercise  certain  graduated  amounts  (beginning  with
one-fifth) of all voting power of the corporation.  The Acquiring Person may not
vote any control shares without first obtaining  approval from the  stockholders
not characterized as "interested stockholders" (as defined below).

        To obtain voting  rights in control  shares,  the Acquiring  Person must
file a statement at the principal office of the issuer  ("Offeror's  Statement")
setting forth certain information about the acquisition or intended  acquisition
of  stock.  The  Offeror's  Statement  may also  request a  special  meeting  of
stockholders  to  determine  the voting  rights to be accorded to the  Acquiring
Person.  A special  stockholders'  meeting  must  then be held at the  Acquiring
Person's expense within 30 to 50 days after the Offeror's Statement is filed. If
a special meeting is not requested by the Acquiring  Person,  the matter will be
addressed at the next regular or special meeting of stockholders.

        At the special or annual  meeting at which the issue of voting rights of
control shares will be addressed,  "interested stockholders" may not vote on the
question of granting  voting  rights to control  the  corporation  or its parent
unless  the  articles  of  incorporation  of  the  issuing  corporation  provide
otherwise.  Abraxas'  Articles  of  Incorporation  do not  currently  contain  a
provision allowing for such voting power.

        If  full  voting  power  is  granted  to  the  Acquiring  Person  by the
disinterested stockholders, and the Acquiring Person has acquired control shares
with a majority or more of the voting power, then (unless otherwise  provided in
the articles of incorporation or bylaws in effect on the tenth day following the
acquisition of a controlling  interest) all  stockholders of record,  other than
the Acquiring Person,  who have not voted in favor of authorizing  voting rights
for the control  shares,  must be sent a notice advising them of the fact and of
their  right to receive  "fair  value" for their  shares.  Abraxas'  Articles of
Incorporation and Bylaws do not provide otherwise. Within 20 days of the mailing
of the notice,  any such  stockholder may demand to receive from the corporation
the "fair  value" for all or part of his shares.  "Fair value" is defined in the
Control  Share  Act as "not less than the  highest  price per share  paid by the
Acquiring Person in an acquisition."

        The Control Share Act permits a corporation to redeem the control shares
in the following two instances,  if so provided in the articles of incorporation
or  bylaws  of  the  corporation  in  effect  on the  tenth  day  following  the
acquisition  of a controlling  interest:  (1) if the  Acquiring  Person fails to
deliver the  Offeror's  Statement  to the  corporation  within 10 days after the
Acquiring  Person's  acquisition  of the  control  shares;  or (2) an  Offeror's
Statement is  delivered,  but the control  shares are not  accorded  full voting
rights by the stockholders. Abraxas' Articles of Incorporation and Bylaws do not
address this matter.

          CERTAIN UNITED STATES AND CANADIAN INCOME TAX CONSIDERATIONS

        The  discussion  below is  intended to be a general  description  of the
material  United States and Canadian tax  consequences  of the Exchange Offer to
holders of the  Exchange  Notes.  It does not take into  account the  individual
circumstances of any particular  investor and does not purport to discuss all of
the  possible  tax  consequences  of the  Exchange  Offer or the,  ownership  or
disposition of the Notes,  and is not intended as tax advice.  The summary below
is general  in nature  and does not  discuss  all  aspects of United  States and
Canadian  income  taxation that may be relevant to a particular  investor in the
light of the investor's particular circumstances.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

        The following is a summary of certain  United States  federal income tax
consequences associated with the acquisition,  ownership, and disposition of the
Notes.  The  following  summary  does not  discuss all of the aspects of federal
income  taxation  that may be relevant to a  prospective  holder of the Notes in
light of his or her  particular  circumstances,  or to certain  types of holders
which are  subject  to  special  treatment  under the  federal  income  tax laws
(including  persons  who hold the  Notes as part of a  conversion,  straddle  or
hedge,  dealers in securities,  insurance companies,  tax-exempt  organizations,
financial  institutions,  broker-dealers  and  S  corporations).  Further,  this
summary  pertains  only to holders  that are citizens or residents of the United
States,  corporations,  partnerships  or other entities  created in or under the
laws of the United States or any political  subdivision  thereof,  or estates or
trusts the income of which is subject to United States federal  income  taxation
regardless  of its source.  In addition,  this summary does not describe any tax
consequences under state, local, or foreign tax laws.

        This summary is based upon the Internal Revenue Code of 1986, as amended
(the   "Code"),   Treasury   Regulations   (the   "Regulations"),   rulings  and
pronouncements  issued by the  Internal  Revenue  Service  ("IRS") and  judicial
decisions  now in  effect,  all of which  are  subject  to change at any time by
legislative,  judicial or administrative action. Any such changes may be applied
retroactively  in a manner that could adversely affect the holders of the Notes.
The  Issuers  have not  sought  and will  not seek any  rulings  from the IRS or
opinions from counsel with respect to the matters discussed below.  There can be
no  assurance  that  the  IRS  will  not  take  positions   concerning  the  tax
consequences of the valuation,  purchase,  ownership or disposition of the Notes
which are different from those discussed herein.

TAX CONSEQUENCES OF THE EXCHANGE OFFER

        An exchange of the Series A Notes for the Exchange Notes pursuant to the
Exchange  Offer should be treated as a  modification  of the Exchange Notes that
does not constitute a material change in their terms.  Accordingly,  an Exchange
Note should be treated as a continuation of the corresponding  Series A Note and
an  exchanging  Holder  should not recognize any gain or loss as a result of the
exchange. In addition, an exchanging Holder's basis in an Exchange Note would be
equal to the basis of the corresponding Series A Note and the holding period for
an  Exchange  Note  would  include  such   Holder's   holding   period  for  the
corresponding Series A Note.

        The Exchange Offer will not have any federal income tax  consequences to
a non-exchanging Holder.

TAXATION OF ACCRUED STATED INTEREST ON NOTES

        Accrued  stated  interest paid on a Note will  generally be taxable to a
holder as ordinary  interest  income at the time it accrues or is  received,  in
accordance with the holder's regular method of accounting for federal income tax
purposes.

        The Company will annually furnish to certain record holders of the Notes
and the IRS information with respect to any stated interest  accruing during the
calendar year as may be required under applicable Regulations.

MARKET DISCOUNT

        If a  holder  purchases  a Note,  other  than  in  connection  with  the
Offering, for less than the stated redemption price of the Note at maturity, the
difference  is  considered  "market  discount,"  unless such  difference  is "de
minimis,"  i.e.,  less than  one-fourth of one percent of the stated  redemption
price of the Note at  maturity  multiplied  by the number of  complete  years to
maturity (after the holder acquires the Note).  Under market discount rules, any
gain realized by the holder on a taxable  disposition  of a Note having  "market
discount," as well as any partial  principal payment made with respect to such a
Note, will be treated

as ordinary  income to the extent of the then "accrued  market  discount" of the
Note. The rules  concerning the calculation of "accrued market discount" are set
forth in the paragraph  immediately below. In addition,  a holder of such a Note
may be  required  to defer the  deduction  of all or a portion  of the  interest
expense on any indebtedness  incurred to purchase or carry a Note having "market
discount."

        Any market  discount will accrue ratably from the date of acquisition to
the maturity date of the Note, unless the holder elects,  irrevocably, to accrue
market discount on a constant  interest rate method.  The constant interest rate
method  generally  accrues  interest at times and in amounts  equivalent  to the
result which would have occurred had the market  discount  been  original  issue
discount computed from the date of the holder's  acquisition of the Note through
the maturity date. The election to accrue market discount on a constant interest
rate method is  irrevocable  but may be made  separately as to each Note held by
the holder.

        Accrual  of market  discount  will not cause the  accrued  amounts to be
included currently in a holder's taxable income, in the absence of a disposition
of, or  principal  payment  on,  the Note.  Nevertheless,  a holder may elect to
currently include market discount in income as it accrues on either a ratable or
constant interest rate method.  In such event,  interest expense relating to the
acquisition  of a Note which  would  otherwise  be deferred  would be  currently
deductible  to the extent  otherwise  permitted  by the Code.  The  election  to
include market discount in income  currently,  once made,  applies to all market
discount  obligations  acquired  by such holder on or after the first day of the
first taxable year to which the election applies and all subsequent years unless
revoked with the consent of the IRS.  Accrued market  discount which is included
in a holder's  gross income will  increase the adjusted tax basis of the Note in
the hands of the holder.

ACQUISITION PREMIUM

        If a  subsequent  holder  acquires a Note for an amount which is greater
than the stated  redemption  price of the Note at maturity,  such holder will be
considered to have purchased such Note with  "amortizable bond premium" equal to
the amount of such excess.  The holder may elect to amortize the premium using a
constant yield method  employing six month  compounding over the period from the
acquisition  date to the  maturity  date of the Note.  Amortized  amounts may be
offset only against  interest  paid with respect to the Note and will reduce the
holder's  adjusted  tax basis in the Note to the extent so used.  Once made,  an
election to amortize  and offset  interest on the Note may be revoked  only with
the  consent  of the IRS and will  apply to all Notes  held by the holder on the
first day of the taxable  year to which the election  relates and to  subsequent
taxable years and to all Notes subsequently acquired by the holder.

SALE, EXCHANGE OR OTHER TAXABLE DISPOSITION OF THE NOTES

        The sale,  redemption or other taxable disposition of a Note will result
in the  recognition  of gain or loss to the  holder  in an  amount  equal to the
difference  between  (i) the amount of cash and fair  market  value of  property
received  (except to the extent  attributable  to the payment of accrued  stated
interest) in exchange therefore and (ii) the holder's adjusted tax basis in such
Note.  A holder's  initial tax basis in a Note  purchased by such holder will be
equal to the issue price of the Note.

        Any gain or loss on the sale, redemption or other taxable disposition of
a Note will be capital gain or loss, except to the extent of any "accrued market
discount,"  assuming a purchaser  of the Note holds such  security as a "capital
asset"  (generally  property held for investment)  within the meaning of Section
1221 of the Code.  Any capital  gain or loss will be  long-term  capital gain or
loss if the Note is held for more than one year and otherwise will be short-term
capital gain or loss.  Payments on such  disposition for accrued stated interest
not previously included in income will be treated as ordinary interest income.

PURCHASE OR REDEMPTION OF NOTES

        Effect of Change of Control  and Asset  Sale.  Upon a Change of Control,
the Issuers are  required to offer to redeem all  outstanding  Notes for a price
equal to 101% of the  principal  amount  thereof plus accrued and unpaid  stated
interest.  See "Description of the Notes -- Redemption -- Optional  Redemption."
Under the Regulations,  such a Change of Control redemption requirement will not
affect the yield or maturity  date of the Notes  unless,  based on all the facts
and circumstances as of the issue date, it is more likely than not that a Change
of Control giving rise to the redemption  will occur.  Upon certain asset sales,
the Issuers will be obligated  to offer to  repurchase  the Notes at one hundred
percent (100%) of the principal  amount thereof plus accrued and unpaid interest
to the date of  redemption.  The Issuers will not treat the Change of Control or
the asset sale  redemption  provisions of the Notes as affecting the calculation
of the yield to maturity of any Note.

        Optional  Redemption.  The Issuers,  at their option, may redeem part or
all of the Notes at any time on or after  November  1, 2000,  at the  redemption
prices set forth  herein.  In  addition,  if the  Issuers  consummate  an Equity
Offering on or before  November 1, 1999,  the Issuers may, at their option,  use
all or a portion  of the  proceeds  from such  Equity  Offering  to redeem up to
thirty-five  percent  (35%)  of the  aggregate  principal  amount  of the  Notes
originally  issued  in the  Offering  at a  redemption  price  equal to  111.5%,
together with accrued and unpaid  interest to the date of redemption;  provided,
however,  that,  after giving  effect to any such  redemption,  at least $139.75
million  aggregate  principal  amount  of the  Notes  remains  outstanding.  See
"Description of the Notes -- Redemption -- Optional Redemption." For purposes of
determining whether the Notes are issued with any "original issue discount," the
Regulations  generally  provide that an issuer will be treated as exercising any
such  option if its  exercise  would lower the yield of the debt  instrument.  A
redemption of Notes at the optional redemption prices,  however,  would increase
rather than  decrease the effective  yield of the debt  instrument as calculated
from the issue date.

        The  Issuers do not  currently  intend to  exercise  any of the  options
described above with respect to the Notes. Should the Issuers exercise an option
and redeem a Note,  the holder of the Note would be required to treat any amount
paid by the Issuers  which  exceeds the Note's  then  principal  balance and all
accrued and unpaid  interest  thereon as an amount  received in exchange for the
Note.

BACKUP WITHHOLDING

        The backup  withholding  rules  require a payor to deduct and withhold a
tax if (i) the payee fails to properly furnish a taxpayer  identification number
("TIN") to the payor,  (ii) the IRS notifies the payor that the TIN furnished by
the  payee is  incorrect,  (iii) the payee  has  failed to report  properly  the
receipt  of  "reportable  payments"  and the IRS has  notified  the  payor  that
withholding  is  required,  or (iv)  there  has been a  failure  of the payee to
certify  under a penalty of perjury  that a payee is not subject to  withholding
under Section 3406 of the Code. As a result,  if any one of the events discussed
above occurs with respect to a holder of Notes, the Company, its paying agent or
other  withholding  agent will be required to withhold a tax equal to 31% of any
"reportable  payment"  made in  connection  with  the  Notes to such  holder.  A
"reportable  payment" includes,  among other things,  amounts paid in respect of
interest  or  original  issue  discount  and  amounts  paid  through  brokers in
retirement of securities.  Any amounts withheld from a payment to a holder under
the backup  withholding rules will be allowed as a refund or credit against such
holder's  federal  income  tax,  provided,  that  the  required  information  is
furnished to the IRS. Certain holders (including, among others, corporations and
certain  tax-exempt  organizations)  are not  subject to the backup  withholding
rules.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

        The following is a general  summary of the Canadian  federal and certain
provincial  income tax  consequences  to a holder of the Notes or Exchange Notes
who is not a resident of Canada,  who does not use or hold, and is not deemed to
use or hold,  the Notes or Exchange  Notes in the course of carrying on business
in Canada and is a person who,  throughout the period during which the Notes are
held  deals at arm's  length  with  Canadian  Abraxas  and is not deemed to deal
otherwise  than at arm's  length with  Canadian  Abraxas.  This summary has been
prepared by reference to the Income Tax Act (Canada) (the "Canadian  Act"),  the
Income Tax  Regulations  (the " Canadian  Regulations"),  with  reference to all
published  proposals  for the  amendment  of the  Canadian  Act and the Canadian
Regulations.


RECEIPT OR DEEMED RECEIPT OF INTEREST

        The terms of the Notes  are such  that  interest  paid or deemed to have
been paid (for  example,  where  Notes are  redeemed at a premium to their issue
price) on the Notes to a non-resident  person with which Canadian  Abraxas deals
at arm's length is exempt from taxation  under the Canadian  Act.  Consequently,
provided the  aforementioned  conditions  are met,  holders of the Notes will on
disposition  thereof  not be  subject  to  Canadian  taxation  in respect of the
receipt or deemed receipt of interest thereon.

DISPOSITIONS OF THE NOTES AND TAX CONSEQUENCES OF THE EXCHANGE OFFER

        The  Canadian  Act does not impose a tax in respect of gains  recognized
upon  disposition of Notes held by  non-resident  persons who do not use or hold
the  Exchange  Notes or the Notes in the course of  carrying  on a  business  in
Canada.  Consequently,  provided that the aforementioned conditions are met, any
gain  recognized  by a  holder  of the  Notes or the  Exchange  Notes on a sale,
redemption or other  disposition  (including any disposition  under the Exchange
Offer) will not be subject to taxation  under the Canadian  Act. Any amount paid
upon a disposition of the Notes or the Exchange Notes which  represents  accrued
and unpaid interest will generally be treated as a deemed receipt of interest.

                        TRANSACTIONS WITH RELATED PARTIES

        Messrs. Watson, Phelps and Riggs were founders of Grey Wolf and in April
1995  purchased  900,000  shares of the  capital  stock of Grey Wolf  (initially
representing  39% of the outstanding  shares) for an aggregate of CDN$90,000 (or
CDN$0.10 per share) in cash. In January 1996, the Company  purchased  20,325,096
shares of the capital stock of Grey Wolf  (representing  78% of the  outstanding
shares) for an aggregate of approximately CDN$4.1 million (or CDN$.20 per share)
in cash. Messrs.  Bruton, Engle, Phelps, Riggs and Watson currently own 13.8% of
the issued and outstanding  capital stock of Grey Wolf. In addition,  Mr. Watson
owns options to purchase up to 450,000 shares of Grey Wolf's capital stock at an
exercise price of CDN$.10 per share.

        Messrs.  Bruton,  Engle, Phelps and Riggs own options to purchase in the
aggregate  up to  2,600,000  shares of capital  stock of Cascade at an  exercise
price of CDN$.20  per share,  and Mr.  Watson  owns  options to  purchase  up to
800,000  shares of Cascade's  capital stock at an exercise  price of CDN$.34 per
share. Cascade currently has 61,365,000 shares of capital stock outstanding.

        Wind River  Resources  Corporation  ("Wind  River"),  all of the capital
stock of which is owned by Mr. Watson, owns a twin-engine airplane. The airplane
is  available  for business use by employees of the Company from time to time at
$385 per hour.  The  Company  paid Wind River a total of $80,678  for use of the
plane during 1995.

        Mr. Watson and members of his family  previously had an outstanding loan
of $328,259,  including  accrued  interest,  to Abraxas as of December 31, 1994.
Abraxas made principal and interest payments of $354,677 on the note during 1995
which  represented  payment of all  principal  and interest due and owing on the
note.

        Abraxas has adopted a policy that transactions, including loans, between
Abraxas and its officers,  directors,  principal stockholders,  or affiliates of
any of them,  will be on terms no less favorable to Abraxas than can be obtained
on an arm's length basis in transactions with third parties and must be approved
by the vote of at least a majority of the disinterested directors.

                          BOOK-ENTRY; DELIVERY AND FORM

        The Certificates representing the Exchange Notes will be issued in fully
registered  form,  without  coupons and will be deposited with, or on behalf of,
the  Depositary,  and registered in the name of Cede & Co., as the  Depository's
nominee  in  the  form  of a  global  Exchange  Note  certificate  (the  "Global
Certificate") or will remain in the custody of the Trustee.

        Except as set forth below, the Global Certificate may be transferred, in
whole and not in part,  only by the Depositary to its nominee to such Depositary
or another  nominee of the  Depositary or by the  Depositary or its nominee to a
successor of the Depositary or a nominee of such successor.

        The Issuers  understand that the Depositary is a  limited-purpose  trust
company which was created to hold securities for its participating organizations
(the   "Participants")  and  to  facilitate  the  clearance  and  settlement  of
transactions  in  such  securities  between   Participants   through  electronic
book-entry  changes  in  accounts  of  its  Participants.  Participants  include
securities brokers and dealers (including the Initial Purchasers),  banks, trust
companies, clearing corporations and certain other organizations.  Access to the
Depository's  book-entry  system is also  available  to  others,  such as banks,
brokers,  dealers and trust companies that clear through or maintain a custodial
relationship  with a  Participant,  either  directly  or  indirectly  ("indirect
participants"). Persons who are not participants may beneficially own securities
held by the Depositary through Participants or indirect participants.

        Pursuant to procedures established by the Depositary (i) upon deposit of
the Global Certificate,  the Depositary will credit the accounts of Participants
with  portions  of the  principal  amount  of the  Global  Certificate  and (ii)
ownership of the Exchange  Notes will be shown on, and the transfer of ownership
thereof will be effected only  through,  records  maintained  by the  Depositary
(with  respect  to  the  interest  on  the   Depository's   participants),   the
Depository's Participants and the Depository's indirect participants.

        The  laws  of some  jurisdictions  require  that  certain  persons  take
physical delivery in definitive form of securities that they own.  Consequently,
the ability to transfer  interests in the Global  Certificate will be limited to
such extent.

        So long as the nominee of the Depositary is the registered  owner of the
Global Certificate,  such nominee will be considered the sole owner or holder of
the Exchange  Notes for all  purposes  under the  Indenture.  Except as provided
below, the owners of interests in the Global Certificate will not be entitled to
have Exchange Notes  registered in their names,  will not receive or be entitled
to receive  physical  delivery of Exchange Notes in definitive form and will not
be considered the owners or holders  thereof under the  Indenture.  As a result,
the  ability  of a  person  having  a  beneficial  interest  in  Exchange  Notes
represented  by the Global  Certificate  to pledge  such  interest to persons or
entities that do not participate in the Depository's system or to otherwise take
actions in respect to such  interest  may be  affected by the lack of a physical
certificate evidencing such interest.

        Neither the  Issuers,  the  Trustee  nor any paying  agent will have any
responsibility  or  liability  for any  aspect  of the  records  relating  to or
payments  made  on  account  of  interests  in  the  Global  Certificate  or for
maintaining, supervising or reviewing any records relating to such interests.

        Principal and interest payments on the Global Certificate  registered in
the name of the  Depository's  nominee  will be made by the Issuers or through a
paying agent to the  Depository's  nominee as the registered owner of the Global
Certificate.  Under the terms of the Indenture, the Issuers and the Trustee will
treat the persons in whose names the Exchange Notes are registered as the owners
of such  Exchange  Notes for the purpose of receiving  payments of principal and
interest  on  such  Exchange  Notes  and  for  all  other  purposes  whatsoever.
Therefore,  neither the Issuers, the Trustee nor any paying agent has any direct
responsibility  or  liability  for the payment of  principal  or interest on the
Exchange Notes to owners of interests in the Global Certificate.  The Depositary
has  advised the Issuers  and the  Trustee  that its present  practice  is, upon
receipt of any payment of  principal  or  interest,  to credit  immediately  the
account of the  Participants  with  payments in amounts  proportionate  to their
respective  holdings in principal amount of interests in the Global  Certificate
as shown on the records of the Depositary. Payments by Participants and indirect
participants to owners of interests in the Global  Certificate  will be governed
by  standing  instructions  and  customary  practices,  as is now the case  with
securities  held for the accounts of customers in bearer form or  registered  in
"street name," and will be the  responsibility  of such participants or indirect
participants.

        If the  Depositary  is at any time  unwilling  or unable to  continue as
depositary and a successor  depositary is not appointed by the Issuers within 90
calendar days, the Issuers will issue  Exchange  Notes in  certificated  form in
exchange for the Global  Certificate.  In addition,  the Issuers may at any time
determine not to have the Exchange Notes  represented  by a Global  Certificate,
and, in such event,  will issue Exchange Notes in certificated  form in exchange
for the Global Certificate.  In either instance,  an owner of an interest in the
Global Certificate would be entitled to physical delivery of such Exchange Notes
in  certificated  form.  Exchange Notes so issued in  certificated  form will be
issued in  denominations  of $1,000 and integral  multiples  thereof and will be
issued in registered form only.

        Neither the Issuers nor the Trustee shall be liable for any delay by the
Depositary or its nominee in identifying  the  beneficial  owners or the related
Exchange  Notes,  and each such  person may  conclusively  rely on, and shall be
protected in relying on, instructions from the Depositary or its nominee for all
purposes  (including  with respect to the  registration  and  delivery,  and the
respective principal amounts, of the Exchange Notes to be issued).

such Series A Notes pursuant to an effective registration statement filed by the
Issuers.

           ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

        Canadian Abraxas is a Canadian corporation,  certain of its officers and
directors  may be residents of various  jurisdictions  outside the United States
and its Canadian counsel,  Burnet,  Duckworth & Palmer, are residents of Canada.
All or a  substantial  portion of the  assets of  Canadian  Abraxas  and of such
persons  may be  located  outside  the  United  States.  As a result,  it may be
difficult  for investors to effect  service of process  within the United States
upon such  persons or to enforce  judgments  obtained  against  such  persons in
United States courts and predicated upon the civil  liability  provisions of the
Securities Act. Notwithstanding the foregoing,  Canadian Abraxas has irrevocably
agreed  that it may be served  with  process  with  respect to actions  based on
offers and sales of securities made hereby in the United States by serving Chris
E. Williford, c/o Abraxas Petroleum Corporation, 500 North Loop 1604 East, Suite
100, San Antonio,  Texas 78232,  Canadian Abraxas' United States agent appointed
for that  purpose.  Canadian  Abraxas has been advised by its Canadian  counsel,
Burnet,  Duckworth  & Palmer,  that there is doubt as to the  enforceability  in
Canada against  Canadian  Abraxas or against any of its  directors,  controlling
persons,  officers or experts who are not  residents  of the United  States,  in
original  actions for  enforcement  of judgments  of United  States  courts,  of
liabilities predicated solely upon United States federal securities laws.

                                  LEGAL MATTERS

        Certain  legal  matters  related to the Notes  offered  hereby are being
passed upon for the Company by Cox & Smith Incorporated,  San Antonio, Texas and
for Canadian Abraxas by Burnet, Duckworth and Palmer, Barristers and Solicitors,
Calgary, Alberta.

                                GLOSSARY OF TERMS

        Unless otherwise  indicated in this Prospectus,  natural gas volumes are
stated at the legal pressure base of the State or area in which the reserves are
located at 60 degrees  Fahrenheit.  Natural gas equivalents are determined using
the ratio of six Mcf of natural  gas to one barrel of crude oil,  condensate  or
NGLs.

        The following  definitions  shall apply to the  technical  terms used in
this Prospectus.

        "Bbl" means barrel or barrels.

        "Bblpd" means barrels per day.

        "Bcf" means billion cubic feet.

        "BOE" means barrel of crude oil equivalent.

        "DD&A" means depletion, depreciation and amortization.

        "Developed  acreage"  means  acreage  which  consists of acres spaced or
assignable to productive wells.

        "Development  well"  means a well  drilled  within the proved  area of a
crude oil or natural gas reservoir to the depth of  stratigraphic  horizon (rock
layer or  formation)  known to be  productive  for the purpose of  extraction of
proved crude oil or natural gas reserves.

        "Dry  hole"  means  an  exploratory  or  development  well  found  to be
incapable  of  producing  either crude oil or gas in  sufficient  quantities  to
justify completion as a crude oil or natural gas well.

        "EBITDA" means earnings from continuing  operations before income taxes,
interest expense, DD&A and other non-cash charges.

        "EBITDA Margin" means EBITDA divided by total operating revenue.

        "Exploratory well" means a well drilled to find and produce crude oil or
natural gas in an unproved  area, to find a new reservoir in a field  previously
found to be  producing  crude oil or  natural  gas in another  reservoir,  or to
extend a known reservoir.

        "Finding cost",  expressed in dollars per BOE, is calculated by dividing
the amount of total exploration and development capital expenditures  (excluding
any  amortization  with  respect to  deferred  financing  fees) by the amount of

                         Report of Independent Auditors



The Board of Directors and Shareholders
Abraxas Petroleum Corporation

         We have audited the accompanying consolidated balance sheets of Abraxas
Petroleum Corporation and Subsidiaries as of December 31, 1994 and 1995, and the
related consolidated  statements of operations,  shareholders'  equity, and cash
flows for each of the three years in the period ended  December 31, 1995.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion,  the  financial  statements  referred to above  present
fairly, in all material respects, the consolidated financial position of Abraxas
Petroleum  Corporation  and  Subsidiaries at December 31, 1994 and 1995, and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity  with generally
accepted accounting principles.



                                                              ERNST & YOUNG LLP

                 ABRAXAS PETROLEUM CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1993, 1994, and 1995
          (Information as to September 30, 1996 and for the Nine Months
                 Ended September 30, 1995 and 1996 is Unaudited)


1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

         Abraxas  Petroleum  Corporation  (the  "Company"  or  "Abraxas")  is an
independent  energy company engaged in the exploration for and the  acquisition,
development,  and  production of crude oil and natural gas  primarily  along the
Texas Gulf Coast and in the  Permian  Basin of west Texas for sale into the U.S.
energy market. The consolidated financial statements include the accounts of the
Company  and  its  subsidiaries.   All  significant  intercompany  accounts  and
transactions have been eliminated in consolidation.

         The accompanying  unaudited interim  consolidated  financial statements
include all adjustments,  consisting of only normal recurring adjustments, that,
in the opinion of  management,  are  necessary to present  fairly the  financial
position as of September 30, 1996 and the results of  operations  and cash flows
for the nine months ended  September 30, 1995 and 1996. The results for the nine
months ended September 30, 1996 are not necessarily indicative of the results to
be expected for the full year.  Information as of September 30, 1996 and for the
nine months ended  September 30, 1995 and 1996, as well as disclosures of events
occurring after March 1996 are unaudited.

USE OF ESTIMATES

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

MARKETABLE SECURITIES

         Management  determines  the  appropriate  classification  of marketable
equity  and  debt  securities  at the  time of  purchase  and  reevaluates  such
designation as of each balance sheet date.  Debt securities that the Company has
both the  positive  intent  and  ability  to hold to  maturity  are  carried  at
amortized  cost.  Debt  securities  that the Company  does not have the positive
intent and ability to hold to maturity and all marketable  equity securities are
classified  as   available-for-sale  or  trading  and  carried  at  fair  value.
Unrealized   holding   gains   and   losses   on   securities    classified   as
available-for-sale  are carried as a separate component of shareholders' equity.
Unrealized  holding  gains and losses on  securities  classified  as trading are
reported in earnings.

ACCOUNTS RECEIVABLE

         Substantially all accounts  receivable relate to transactions  relating
to crude oil and natural gas  activities  with  customers or joint owners in the
United States. The Company does not require collateral for its receivables.



<PAGE>



                                      
EQUIPMENT INVENTORY

         Equipment  inventory  consists of casing and tubing,  and is carried at
the lower of cost or market.

OIL AND GAS PROPERTIES

         The Company  follows the full cost method of  accounting  for crude oil
and  natural  gas  properties.  Under this  method,  all costs  associated  with
acquisition,  exploration, and development are capitalized. The Company does not
capitalize   internal   costs,   except  for  the  expenses  of  its  geologist.
Depreciation,  depletion,  and amortization  (DD&A) of crude oil and natural gas
properties  are  based  on  the   unit-of-production   method.   If  unamortized
capitalized  costs are in excess of the discounted  present value of future cash
flows relating to proved reserves (ceiling), a charge to operations is recorded.
No gain or loss is recognized  upon sale or disposition of crude oil and natural
gas properties, except in unusual circumstances.

OTHER PROPERTY AND EQUIPMENT

         Other  property  and  equipment  are  recorded  on the  basis  of cost.
Depreciation  is provided at amounts  calculated to amortize costs of the assets
over their estimated useful lives using the straight-line method. Major renewals
and  betterments  are  recorded  as  additions  to the  property  and  equipment
accounts.  Repairs  that do not improve or extend the useful lives of assets are
expensed.

STOCK-BASED COMPENSATION

         The  Company  grants  stock  options  for a fixed  number  of shares to
employees  and directors  with an exercise  price equal to the fair value of the
shares at the date of grant.  The Company  accounts for stock  option  grants in
accordance with APB Opinion No. 25,  "Accounting for Stock Issued to Employees,"
and,  accordingly,  recognizes  no  compensation  expense  for the stock  option
grants.

REVENUE RECOGNITION AND MAJOR CUSTOMERS

         The Company  recognizes  crude oil and  natural  gas  revenue  from its
interest  in  producing  wells as crude oil and  natural  gas is sold from those
wells.  For the years ended December 31, 1993,  1994, and 1995, the Company sold
30%, 35%, and 20%, respectively, of its total crude oil and natural gas sales to
one purchaser.  Additionally,  for the years ended December 31, 1993,  1994, and
1995,  approximately  80%, 74%, and 64%,  respectively,  of the Company's  total
crude oil and natural gas sales were made to five purchasers.

DEFERRED FINANCING FEES

         Deferred financing fees are being amortized on a level yield basis over
the term of the related debt.



<PAGE>


FEDERAL INCOME TAXES

         The Company records income taxes under Financial  Accounting  Standards
Board Statement No. 109 using the liability method. Under this method,  deferred
tax assets and liabilities are determined based on differences between financial
reporting  and tax bases of assets and  liabilities  and are measured  using the
enacted  tax rates and laws that  will be in  effect  when the  differences  are
expected to reverse.

NET INCOME (LOSS) PER COMMON SHARE

         Net income  (loss) per common  share is computed by dividing net income
(loss)  (adjusted  for  dividends  on preferred  stock) by the weighted  average
number of shares of common  stock  outstanding  during the period.  The weighted
average  number of shares  includes  the number of shares that would be issuable
under the  Contingent  Value Rights  Agreement (CVR  Agreement),  if the current
market value of the Company's  common stock at year-end is less than a specified
target  price  (see Note 7).  Common  stock  equivalents,  including  any shares
issuable  under the CVR  Agreement,  are not  considered in the  computation  of
periods with a loss, as their effect is anti-dilutive.

RECLASSIFICATIONS

         Certain  balances  for  1993  and  1994  have  been   reclassified  for
comparative purposes.

2.  ACQUISITIONS AND DIVESTITURES

TEXAS GULF COAST PROPERTIES ACQUISITION

         In October 1995, the Company acquired  additional  working interests in
certain  producing crude oil and natural gas properties in which the Company had
an  existing  working  interest  ownership.  The net  purchase  price to Abraxas
amounted to approximately $635,000.  Revenues and expenses have been included in
the consolidated financial statements since October 1, 1995.

WEST TEXAS PROPERTIES ACQUISITION

         In July 1994, the Company  acquired from various  parties  interests in
certain  producing  crude oil and natural gas  properties  located in West Texas
(the West Texas  Properties).  The net  purchase  price to Abraxas  amounted  to
approximately $28,242,000 including closing costs of approximately $383,000. The
acquisition was accounted for as a purchase and the purchase price was allocated
to  crude  oil and  natural  gas  properties  based on the  fair  values  of the
properties  acquired.  The  transaction  was financed  principally by additional
borrowings  under the Company's  credit agreement with First Union National Bank
of North  Carolina  (First  Union),  referred to in Note 6. Revenue and expenses
from the West Texas Properties have been included in the consolidated  financial
statements since July 1, 1994.



<PAGE>


OVERRIDING ROYALTY INTEREST ACQUISITION

         In June 1994,  the Company  acquired  from its prior  secured  lenders,
Endowment  Energy  Partners,  L.P.  (EEP)  and  Endowment  Energy  Co-Investment
Partnership (EECIP), 80% of the previously granted overriding royalty interests.
The net purchase price of  approximately  $5,174,100  consisted of $600,000 cash
and 45,741 shares of the Company's Series B 8% nonvoting cumulative  convertible
preferred  stock with a par value of $100 per share  (Series B Preferred) at the
time of issuance.  The preferred  shares were recorded at $4,574,100 at the date
of the  acquisition.  In  November  1995,  the  Company  exchanged  the Series B
Preferred  for an equal number of shares of its Series 1995-B  Preferred  Stock,
par value $.01 per share,  with a liquidation  preference of $100 per share. The
preferred  shares are  convertible  into 508,182 shares of the Company's  common
stock.  The acquisition was accounted for as a purchase,  and the purchase price
was allocated to crude oil and natural gas  properties  based on the fair values
of the properties  acquired.  The cash portion of the  transaction  was financed
principally under the Company's credit agreement with First Union.  Revenues and
expenses  related to these  properties  have been  included in the  consolidated
financial statements since July 1, 1994.

MOBIL ACQUISITION

         In April 1993, the Company  acquired from Mobil Producing Texas and New
Mexico,  Inc. (Mobil)  interests in certain  producing crude oil and natural gas
properties  and  natural  gas  processing  plants  located in Texas (the  Sinton
Properties).  The net  purchase  price  to  Abraxas  amounted  to  approximately
$19,600,000  ($41,000,000  gross  purchase  price plus closing costs of $472,000
less the sale of 50% of the  Company's  interest to an unrelated  pension  trust
fund for  $21,000,000 and the  reimbursement  from Mobil for net production from
January 1, 1993 through the closing date).  The acquisition was accounted for as
a purchase  and the  purchase  price was  allocated to crude oil and natural gas
properties,  natural  gas  processing  plants  and other  assets  based  upon an
estimate of the fair values of the  properties  acquired  and the  reimbursement
from  Mobil  described  above.  The  transaction  was  financed  principally  by
additional  borrowings  under  the  Company's  financing  agreement  with  EECIP
referred to in Note 6. Under the financing  agreement,  the Company was required
to assign a 10% overriding  royalty interest in and to the future gross revenues
to be received  from the sales of crude oil and natural  gas  produced  from the
acquired properties.  Revenues and expenses from the Sinton Properties have been
included in the consolidated financial statements since April 1, 1993.

GAELIC PROPERTIES

         In January  1993,  the  Company  acquired  from  Gaelic  Resources  the
remaining  75%  working  interest  in the  Alice  Deep  wells for  $300,000  and
18,200,000  shares of Gaelic  common stock for $300,000.  The purchase  price of
$600,000 cash was financed  through an increase in the financing  agreement with
EEP.  Revenues and expenses of the Gaelic  Properties  have been included in the
consolidated financial statements since January 1, 1993.

$2,550,000.

3.  DISCONTINUED OPERATIONS

         In January 1995,  the Company  entered into a plan to  discontinue  the
operations of its coal  properties  and  commenced the permanent  closing of the
mine. As of December 31, 1994,  the Company wrote off its investment in its coal
properties and related  equipment,  eliminated the related minority  interest in
the coal entities, and established a liability of $150,000 pursuant to a plan to
discontinue   operations   for  future  costs   related  to  closing  the  mine.
Additionally,  during 1994,  the Company  sold its interest in Castle  Minerals,
Inc., which was acquired in 1992 to finance the coal  operations,  for $371,000,
net of expenses  related to the sale (see Note 11). The Company  recorded a loss
on these transactions in 1994 of $987,543.  The revenues from coal sales for the
years ended 1993, 1994, and 1995 were $23,759, $104,310, and $-0-, respectively.

4.  MARKETABLE SECURITIES

         In May 1993, the Financial  Accounting Standards Board issued Statement
of Financial  Accounting  Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities" (SFAS 115),  effective for fiscal years beginning
after December 15, 1993. At December 31, 1994, the Company's  marketable  equity
securities were classified as  available-for-sale.  As of December 31, 1994, the
Company recognized a decrease of approximately $244,000 in shareholders' equity,
representing the recognition in shareholders' equity of unrealized depreciation,
net of taxes, for the Company's investment in equity securities determined to be
available-for-sale, previously carried at the lower of cost or market.

         The marketable  securities  represent an equity investment in a foreign
corporation  which the Company considers as  available-for-sale.  The securities
had an original cost of $570,000 at December 31, 1994 and 1995, and at September
30,  1996.  In October  1996,  the Company  sold its  investment  in  marketable
securities, realizing a loss of $235,197. Such loss was recorded as of September
30, 1996.

         Prior to the adoption of SFAS 115, and to increase the carrying  amount
of its  marketable  securities  portfolio to market,  a recovery of $235,000 was
recorded during 1993.

         In June 1994,  the Company  entered into a credit  agreement with First
Union which was  subsequently  amended  during the year.  The  Company  borrowed
$40,906,652  during 1994 under the agreement.  The  borrowings  were composed of
advances  of  $32,906,652  under a revolving  line of credit  which was due June
1997,  and  $8,000,000  under a term note which was due June 15, 1995. In August
1995,  the Company  amended the credit  agreement  with First  Union.  Under the
amended  credit  agreement,  the  Company  has  two  lines  of  credit,  one for
$23,000,000 and one for  $17,000,000 and two term notes,  one for $3,450,000 and
one for  $2,550,000.  At December 31, 1995, the Company's  borrowings  under the
credit agreement were  $41,556,651.  The borrowings were composed of advances of
$12,656,651  and  $22,900,000  under the revolving lines of credit which are due
June 30, 1997, and  $6,000,000  under the term notes which are also due June 30,
1997. The interest rate for the revolving  credit lines is, at the option of the
Company,  either (a) the higher of First  Union  prime plus 1/4% or the  federal
funds rate plus 3/4%, floating,  payable monthly, or (b) LIBOR plus 2 1/4% (30-,
60-, 90-, and 180-day options), with interest payable the earlier of maturity of
each LIBOR tranche or quarterly. The interest rate for the term notes is, at the
option of the  Company,  either (a) the higher of First Union prime plus 3/4% or
the federal funds rate plus 1 1/4%, floating, payable monthly, or (b) LIBOR plus
3 1/4% (30-, 60-, 90-, and 180-day  options),  with interest payable the earlier
of maturity  of each LIBOR  tranche or  quarterly.  At December  31,  1995,  the
$12,656,651 revolver carried interest at 8.19%, the $22,900,000 revolver carried
interest  at 8.06%,  and the term  notes at 8.16%.  The  revolvers  provide  for
borrowing  based  principally on the Company's crude oil and natural gas reserve
base, which was $44,000,000 at December 31, 1995.

         In April 1996,  the Company  amended  the credit  agreement  with First
Union,  extending  the due date to June  1999.  In  accordance  with the  credit
agreement,  in July 1996 the  borrowing  base was  adjusted to  $35,000,000.  At
September 30, 1996, the Company's borrowings under this line of credit was $-0-.

         The  revolving  lines of  credit  may be  extended,  at  First  Union's
discretion,  and are subject to  semi-annual  redeterminations  of the borrowing
base each June and  December.  The  borrowings  under  the  First  Union  credit
agreement are secured by a first-priority mortgage on all of the Company's crude
oil and natural gas properties and gas plants, as well as a security interest in
accounts receivable,  inventory,  contracts,  and general  intangibles,  and are
guaranteed by the Company.  The First Union credit agreement requires compliance
with  certain  covenants  including,  among other  things,  the ratio of current
assets to  current  liabilities,  excluding  any  current  portion of the credit
agreement,  of not  less  than  1.0 to  1.0;  and  the  ratio  of the  Company's
indebtedness  compared to annualized net income plus non-cash  charges shall not
be greater  than 7.5 to 1.0  through  December  31,  1995,  and 5.0 to 1.0 after
December  31,  1995.  In August 1996,  the ratio of the  Company's  indebtedness
compared to annualized  net income plus  non-cash  charges was amended to 8.0 to
1.0 through  December 31, 1996,  effective  December 31, 1995, and to 5.0 to 1.0
after  December 31, 1996. In addition,  the credit  agreement  requires  certain
financial reporting  requirements and limits the payments of dividends on common
stock,  additional  indebtedness,  mergers and  acquisitions.  Loan fees paid in
connection  with  the  origination  of the  credit  agreement  and  the  amended
agreement have been classified as deferred  financing  fees. In addition,  terms
include a commitment fee of 1/2 of 1% per annum, payable quarterly in arrears on
the average  unused  portion of the borrowing  base.  The debt's  carrying value
approximate its fair values.



<PAGE>


         On June 30, 1994,  the Company  secured  advances under the First Union
facility  adequate to extinguish the total debt and accrued interest owed to the
Company's  previous  lenders,  EEP and EECIP.  The  prepayment  resulted  in the
Company  recording an extraordinary  debt  extinguishment  charge of $1,171,832,
representing the reduction of the deferred financing fees related to the EEP and
EECIP debt origination.

         In August  1993,  EEP and EECIP  agreed to permit the Company to prepay
$14,000,000  of the  outstanding  balances  of the  Company's  notes  out of the
proceeds of the  Company's  common  stock  offering.  In  consideration  of this
agreement,  the Company issued an aggregate of 50,000 shares of its common stock
to EEP and EECIP's general partners,  EEP and Endowment Energy Partners II, L.P.
(EEP II) and, upon making the prepayment of $14,000,000 in October 1993,  issued
an additional 66,666 shares of common stock to EEP and EEP II. The prepayment of
debt and the issuance of the above-discussed  shares of common stock resulted in
the Company recording an extraordinary debt extinguishment charge of $3,036,000,
representing  the fair value of the shares of common stock issued of  $1,325,000
and the reduction of the deferred  financing fees of $1,711,000 in proportion to
the amount of debt  prepaid.  The  issuance  of the above  shares  resulted in a
corresponding increase in common stock and additional paid-in capital.

         The Company has approximately $90,000 of standby letters of credit open
at December 31, 1995. Approximately $134,419 of cash is restricted and in escrow
related to the letters of credit.

         Holders of common stock are entitled to one vote for each share and are
not entitled to preemptive  rights to subscribe to  additional  shares of common
stock issued by the Company. Holders are entitled to receive dividends as may be
declared  by the  Board of  Directors,  subject  to the  rights  of  holders  of
preferred stock and the terms of the Company's credit agreement,  which restrict
the payment of dividends.

         In October  1993,  the Company  issued an additional  2,250,000  common
shares through a public offering, resulting in net proceeds of $23,045,135. Loss
per share,  calculated on a  supplemental  basis as if the  foregoing  event had
occurred  at the  beginning  of the year,  would have been $(.16) loss per share
from  continuing  operations  and  $(.37)  net loss per share for the year ended
December 31, 1993.  The  supplemental  earnings per share  assumes that interest
expense would have been reduced by $939,000 from the  prepayment of  $14,000,000
of long-term  debt from the proceeds of the  issuance of the  additional  common
stock.  The  preferred  stock was assumed to be converted as of the beginning of
1993;  therefore,  income was not  required to be adjusted for  preferred  stock
dividends.



<PAGE>


         In 1994, the Board of Directors adopted a Shareholders' Rights Plan and
declared a dividend of one Common Stock  Purchase  Right (Rights) for each share
of common stock. The Rights are not initially exercisable.  Subject to the Board
of Directors'  option to extend the period,  the Rights will become  exercisable
and will  detach  from the  common  stock ten days after any person has become a
beneficial owner of 20% or more of the common stock of the Company or has made a
tender offer or exchange offer (other than certain qualifying offers) for 20% or
more of the common stock of the Company.

         Once the Rights  become  exercisable,  each Right  entitles the holder,
other than the  acquiring  person,  to purchase for $20 one-half of one share of
common stock of the Company having a value of four times the purchase price. The
Company  may  redeem  the  rights  at any time for  $.01  per  Right  prior to a
specified  period of time after a tender or  exchange  offer.  The  Rights  will
expire in November 2004, unless earlier exchanged or redeemed.

         In November 1995, the Company issued 1,330,000  units,  each consisting
of one share of common stock and one  Contingent  Value Right  (CVR),  through a
private placement, resulting in net proceeds of $10,063,105. Each CVR allows the
holder the right to acquire  additional  shares of common  stock  under  certain
circumstances.  See further discussion of CVRs below. Loss per share, calculated
on a supplemental  basis as if the foregoing event had occurred at the beginning
of the year,  would have been $(.19) loss per share for the year ended  December
31, 1995.  The  supplemental  earnings per share assumes that  interest  expense
would  have been  reduced by  $455,800  from the  prepayment  of  $5,300,000  of
long-term debt from the proceeds of the issuance of the units for the year ended
December 31, 1995.

PREFERRED STOCK

         In June 1994,  in  connection  with the  Company's  acquisition  of the
overriding  royalty interest from EEP and EECIP,  45,741 shares of the Company's
Series B 8%, nonvoting cumulative  convertible  preferred stock with a par value
of $100 were issued. The preferred shares are convertible into 508,182 shares of
the Company's  common stock.  Preferred stock dividends  during 1995 amounted to
$365,928.  During  1995,  the  Company  exchanged  the  Series  B 8%,  nonvoting
cumulative  convertible  preferred stock for an equal number of shares of Series
1995-B cumulative convertible preferred stock which have a par value of $.01 per
share and a stated value of $100 per share.

         The Board of  Directors  of the  Company is  authorized  to approve the
issuance of one or more classes or series of  preferred  stock  without  further
authorization of the Company's shareholders. At December 31, 1992, 24,910 shares
of  preferred  stock were  outstanding.  The stock was  entitled to a cumulative
dividend of $10 per share,  payable in shares of preferred stock, was redeemable
at the option of the Company,  and was convertible into common stock at the rate
of 9.271 shares of common  stock for each share of  preferred  stock plus unpaid
dividend.  In October  1993,  in  connection  with the  Company's  common  stock
offering,  the  holders  of the  preferred  stock  converted  all  of  the  then
outstanding  preferred shares,  including the preferred shares issued in payment
of approximately  $934,000 cumulative dividends in arrears,  into 317,539 shares
of common stock.

CONTINGENT VALUE RIGHTS (CVR)

         The CVRs were issued under the CVR Agreement  between the Company,  the
purchasers,  and First Union, as rights agent. The CVR Agreement  provides that,
subject to adjustment as described below, the Company shall issue to each holder
of the CVRs on the Maturity Date (November 17, 1996),  unless the Company shall,
in its sole discretion,  extend the Maturity Date to the Extended  Maturity Date
(November 17, 1997),  then on the Extended  Maturity Date, a number of shares of
common stock, if any, equal to (a) the Target Price ($10.00 on the Maturity Date
or $12.50 on the Extended  Maturity Date) minus the current market value divided
by (b) the current market value; provided,  however, that in no event shall more
than one  share  of  common  stock be  issued  in  exchange  for each CVR at the
Maturity  Date or more than 1.5 shares of common stock be issued in exchange for
each CVR at the Extended Maturity Date. Such  determination by the Company shall
be final and binding on the Company and the holders of CVRs.

         If the median of the average  prices of the common  stock for the three
20-trading day periods  immediately  preceding the Maturity Date or the Extended
Maturity Date, as the case may be, equals or exceeds $10.00 on the Maturity Date
or $12.50 on the Extended Maturity Date (if the Maturity Date is extended by the
Company to the  Extended  Maturity  Date),  as the case may be, no shares of the
common stock will be issuable  with respect to the CVRs.  In addition,  the CVRs
will  terminate if the per share market value equals or exceeds the Target Price
for any period of 30 consecutive  trading days during either the period from and
after  November 17, 1995 to and  including  November 17, 1996, or from and after
November 17, 1996 to and including November 17, 1997.

         In the event that the Company  determines  that no shares of the common
stock are  issuable  with  respect to the CVRs to such  holders,  the CVRs shall
terminate and become null and void and the holders shall have no further  rights
with  respect  thereto.  If the  Maturity  Date of the CVR  Agreement  had  been
December 31, 1995 and  September 30, 1996, an aggregate of 746,480 and 1,117,200
shares,  respectively,  of common stock would have been issued to the holders of
the CVRs.

         Should any  additional  shares of common stock be required to be issued
under the terms of the CVR Agreement,  such issuance will be considered to be an
adjustment to the original sales price per share received in connection with the
sale of the associated common shares; accordingly, the Company will increase its
common stock for the par value related to the additional shares at the time such
shares are issued with a corresponding decrease in additional paid-in capital.

TREASURY STOCK

         During the nine months ended September 30, 1996, the Company  purchased
68,140 shares of its common stock at a cost of $372,254, which are being held as
treasury stock.

8.  STOCK OPTION PLANS AND WARRANTS

         The  Company  grants  options  to  its  officers,  directors,  and  key
employees under its 1984 Incentive Stock Option Plan, Non-Qualified Stock Option
Plan, Key Contributor Stock Option Plan,  Long-Term Incentive Plan, and Director
Stock Option Plan.

         The  following  is a summary of activity in the stock  option plans for

               (1) During the nine months ended  September 30, 1996, the Company
      amended the  exercise  price to $6.75 per share on all  previously  issued
      options with an exercise price greater than $6.75 per share.

               (2) Includes 70,000 options granted at an exercise price of $5.00
      for which  vesting does not begin until the closing price of the Company's
      common stock exceeds $8.00 per share.



<PAGE>


         In addition to stock options granted under the plans  described  above,
the Long-Term Incentive Plan also provides for the right to receive compensation
in cash, awards of common stock, or a combination thereof. In 1994 and 1995, the
Company made direct  awards of common  stock of 6,111  shares and 4,800  shares,
respectively.

         The Company also has adopted the  Restricted  Share Plan for  Directors
which  provides  for  awards of common  stock to  nonemployee  directors  of the
Company who did not, within the year immediately  preceding the determination of
the  director's  eligibility,  receive  any award  under  any other  plan of the
Company.  In 1994 and 1995,  the Company  made direct  awards of common stock of
2,400 shares and 3,072 shares, respectively.

         During  the  nine  months  ended  September  30,  1996,  the  Company's
shareholders  approved the Abraxas Petroleum  Corporation  Director Stock Option
Plan (Plan),  which  authorizes the grant of nonstatutory  options to acquire an
aggregate of 104,000  common  shares to those  persons who are directors and not
officers of the Company.  Under the Plan,  each of the seven eligible  directors
was granted an option to purchase 8,000 common shares at $6.75.

STOCK WARRANTS

         In connection with the EEP and EECIP financing  agreements entered into
in 1992 and 1993, the Company  granted stock warrants  covering 90,000 shares at
$5.25 per share and  135,000  shares at $7.00 per share.  During  1994,  211,500
warrants were  exercised to purchase  common stock for  $1,323,000.  In 1995, no
warrants  were  exercised  by EEP or  EECIP.  For the nine  month  period  ended
September 30, 1996, no warrants were exercised.

         In connection  with an amendment and increase in the facility under the
credit  agreement with First Union and the extension of the due date on the term
note, the Company granted stock warrants to First Union covering  424,000 shares
of its  common  stock at an average  price of $9.79 a share.  The  warrants  are
exercisable  in whole or in part through  December 1999 and are  nontransferable
without the consent of the Company.

         At December 31, 1995, the Company has  approximately  6,470,000  shares
reserved for future  issuance for  conversion  of its stock  options,  warrants,
Rights,  preferred stock, CVRs, and incentive plans for the Company's  Directors
and employees.

9.  INCOME TAXES

         Deferred  income  taxes  reflect  the  net  tax  effects  of  temporary
differences between the carrying amounts of assets and liabilities for financial
reporting  purposes  and the amounts used for income tax  purposes.  Significant
components of the Company's deferred tax liabilities and assets are as follows:

                                                             December 31

                                                         ========== ============

         At December  31,  1995,  the Company  had,  subject to the  limitations
discussed  below,  $18,127,000  of net  operating  loss  carryforwards  for  tax
purposes,  of which  approximately  $4,697,000  are  available  for  utilization
without limitation.  These loss carryforwards will expire from 2002 through 2010
if not utilized.

         As the result of the acquisition of certain  partnership  interests and
crude oil and natural gas properties in 1990 and 1991, an ownership change under
Section 382 of the Internal  Revenue  Code of 1986,  as amended  (Section  382),
occurred  in December  1991.  Accordingly,  it is  expected  that the use of net
operating loss carryforwards  generated prior to December 31, 1991 of $6,916,000
will be limited to approximately $235,000 per year.

         During  1992,  the  Company  acquired  100% of the  common  stock of an
unrelated corporation. The use of net operating loss carryforwards of $3,607,000
acquired in the acquisition are limited to approximately $115,000 per year.

         As a result of the  issuance of  additional  shares of common stock for
acquisitions  and sales of common stock,  an additional  ownership  change under
Section 382 occurred in October 1993.  Accordingly,  it is expected that the use
of all net operating loss carryforwards generated through October 1993 of



<PAGE>


$13,430,000 will be limited to approximately $1,034,000 per year, subject to the
lower  limitations  described  above.  Of the  $13,430,000  net  operating  loss
carryforwards  existing at October 1993, it is anticipated  that the maximum net
operating  loss that may be  utilized  before it expires is  $7,188,000.  Future
changes in ownership may further limit the use of the Company's carryforwards.

         In addition to the Section 382 limitations,  uncertainties  exist as to
the future  utilization of the operating loss  carryforwards  under the criteria
set forth under FASB Statement No. 109. Therefore, the Company has established a
valuation  allowance of  $5,482,000  and  $5,656,000  for deferred tax assets at
December 31, 1994 and 1995, respectively.

         The reconciliation of income tax attributable to continuing  operations
computed at the U.S. federal statutory tax rates to income tax expense is:

10.  LEASES

         The Company  leases its  existing  primary  office space for $8,591 per
month under a  noncancelable  lease expiring on June 30, 1998.  During 1995, the
Company  entered  into a  noncancelable  lease for new primary  office  space at
$13,700 per month through March 2001 and $18,975 per month through March 2006.

         During the years ended  December 31, 1993,  1994, and 1995, the Company
incurred  rent  expense  of  approximately  $143,000,  $108,000,  and  $103,000,
respectively.  Future  minimum  rental  payments  are as follows at December 31,
1995:

     1996 ................................   $      225,816
     1997 ................................          219,016
     1998 ................................          217,848
     1999 ................................          164,448
     2000 ................................          227,700
     Thereafter ..........................        1,138,500

         Aggregate  future minimum  rentals to be received  under  noncancelable
subleases as of December 31, 1995 amount to $92,664.

11.  INVESTMENT IN COAL PROPERTIES

         Over the  past  years  the  Company,  through  a  subsidiary,  had been
developing certain coal properties in Colorado. During this period,  development
costs  along  with  interest  on its bank  debt have  been  capitalized  as coal
properties.  The  interest  accrued  into the  subsidiary  bank debt,  which was
nonrecourse to the parent.
Effective July 1, 1992, the subsidiary  commenced  expensing  interest and other
related operating costs.

         In March  1992,  the  subsidiary  acquired  for  $15,000 a  controlling
interest in an inactive Vancouver publicly traded company, Castle Minerals, Inc.
(CMI).  In December 1992, the  subsidiary  received  approval from the Vancouver
Stock  Exchange,  whereby the  subsidiary  contributed  all of its  coal-related
assets to CMI in exchange for additional  shares amounting to approximately  86%
of the capital stock of CMI.

         During  1992,  the  Company  recorded as a charge  against  operations,
$3,137,000,  representing interest expense and other operating costs of the coal
mine of approximately $512,000 and a reduction in the carrying value of the coal
mine by  $2,625,000.  The estimated  fair value of the coal mine was  determined
based upon an appraisal  that assumes the startup of commercial  production  and
the availability of markets in which to sell the coal production.

         On April 14, 1993, the Company entered into a letter agreement with the
lender of the subsidiary bank debt (Bank) effective March 31, 1993,  wherein the
Company  assumed a portion of the subsidiary  bank debt by issuing a note to the
Bank in the principal amount of $1,000,000.  In addition,  the subsidiary issued
to the Bank its  preferred  stock with a par value of  $2,000,000,  and the Bank
canceled the  subsidiary  bank debt of  $4,302,675.  The preferred  stock of the
subsidiary  requires no  dividends  prior to April 1, 1996 and at 8%  thereafter
payable in cash or property of the subsidiary,  carries a liquidation preference
of $2,000,000,  and is redeemable at the option of the subsidiary at $2,000,000.
The preferred  stock had been recorded at  management's  estimate of the stock's
fair  market  value of  $840,000  and was  carried as  minority  interest in the
December 31, 1993 balance sheet. A pretax gain of $2,462,664,  representing  the
excess of the carrying value of the subsidiary bank debt over the estimated fair
value of the  preferred  stock and the future cash  payments  of the  $1,000,000
subsidiary  bank debt assumed by the Company,  was recorded as an  extraordinary
item for the year ended December 31, 1993. On October 29, 1993, the Company paid
its note of $1,000,000  plus interest to the Bank. In December 1994, the Company
discontinued its operation of the coal properties (see Note 3).

12.  BENEFIT PLANS

         During  1993,  the  Company  established  a defined  contribution  plan
(401(k)) covering all eligible  employees of the Company.  No contributions were
made by the Company  during  1993,  1994,  or 1995.  The  employee  contribution
limitations  are determined by formulas  which limit the upper  one-third of the
plan  members  from  contributing  amounts  that  would  cause  the  Plan  to be
top-heavy.  The  overall  contribution  is  limited  to the lesser of 20% of the
employee's annual compensation or $9,240.

13.  INCENTIVE BONUS PLAN

         In January 1995, the Company created the Technical  Employees Incentive
Bonus Plan,  whereby  technical  employees have an incentive to find and develop
crude oil and  natural  gas  reserves on an  economic  basis  beneficial  to the
Company  and  its  shareholders.   Participants  are  any  technical   employees
(geologist, geophysicist, engineer) not covered by another incentive bonus plan.
A participant may earn a monetary bonus of up to 65% of the  participant's  base
salary each year.  The bonuses are  determined in the first quarter of each year
and are based upon the amount of new proved developed  producing reserves booked
each  year  on  approved  exploration  and  exploitation  projects  taking  into
consideration the cost per equivalent barrel of developing the new reserves.  No
bonuses were paid under this plan in 1995.

14.  CONTINGENCIES

         From time to time,  the Company is involved in  litigation  relating to
claims  arising  out of its  operations  in the normal  course of  business.  At
December 31, 1995 and  September  30,  1996,  the Company was not engaged in any
legal proceedings that are expected, individually or in the aggregate, to have a
material adverse effect on the Company's financial statements.

15.  COMMODITY SWAP AGREEMENT

         In December 1995,  the Company  entered into a commodity swap agreement
with First Union.  Under the commodity swap agreement,  the Company  receives or
makes  payments  to First Union  based on the  differential  between a fixed and
variable price for natural gas. At December 31, 1995 and September 30, 1996, the
Company  had agreed to exchange  payments  monthly on 5,000 MMBTU of natural gas
per day,  beginning in March 1996 and extending through November 1996. Under the
swap agreement, the Company receives fixed prices averaging $1.747 per MMBTU and
pays a variable price based on the arithmetic  average of the last three trading
days' settlement price of the first nearby contract for natural gas as quoted by
the New York Mercantile  Exchange.  For the year ended December 31, 1995,  there
was no effect on income  from  continuing  operations  as there was no  activity
related to the swap  agreement,  which begins in March 1996.  At  September  30,
1996, the effect on income was a loss of $510,767.

16.  SUBSEQUENT EVENTS

         In January 1996, the Company made a $3,000,000 investment in Grey Wolf,
a privately held Canadian corporation,  which in turn invested these proceeds in
newly  issued  shares of Cascade Oil and Gas Ltd.  (Cascade),  an  Alberta-based
corporation  whose shares are traded on the Alberta Stock Exchange.  The Company
owns 78% of the outstanding  capital stock of Grey Wolf, and, through Grey Wolf,
the Company owns approximately 52% of the outstanding  capital stock of Cascade.
Certain officers and directors of the Company own approximately 6% of the common
stock of Grey Wolf and serve as directors of Grey Wolf.

         In March 1996, the Company sold all of its interest in its Portilla and
Happy  Fields  to  an  unrelated  purchaser   (Purchaser  or  Limited  Partner).
Simultaneously  with this  sale,  the  Limited  Partner  also  acquired  the 50%
overriding  royalty  interest  in the  Portilla  field  owned by the  Commingled
Pension Trust Fund (Petroleum II), the trustee of which is Morgan Guaranty Trust
Company of New York (Pension  Fund). In connection with the purchase of both the
Company's interest in the Portilla and Happy Fields and the

<PAGE>


         Pension  Fund's   interest  in  the  Portilla  Field   (together,   the
Properties),  the Limited  Partner  obtained a loan (Bank  Loan)  secured by the
Properties  and  contributed  the  Properties  to  Portilla-1996,  L.P., a Texas
limited partnership (Partnership).  A subsidiary of the Company,  Portilla-Happy
Corporation  (Portilla-Happy),  is the general partner of the  Partnership.  The
aggregate  purchase  price  received by the Company  was  $17,600,000,  of which
$2,000,000 was used to purchase a minority  interest in the  Partnership,  which
has been  accounted  for using the equity  method.  At September  30, 1996,  the
Company's investment in and advances to the Partnership  represents the original
investment of  $2,000,000  and advances  made to the  Partnership  primarily for
development  drilling  net of  production  revenue  collected  by the Company on
behalf of the Partnership.

17.  ACQUISITIONS AND RELATED FINANCING (UNAUDITED)

         On  September  30,  1996,  the Company  acquired  interests  in certain
producing crude oil and natural gas properties  located in the Wamsutter area of
southwestern Wyoming (the Wyoming Properties) from Enserch Exploration, Inc. The
initially agreed to purchase price of $47,500,000 was adjusted to $45,856,000 to
reflect the preliminary  estimate of net production revenue which accrued to the
Company from April 1, 1996, the effective date,  until closing,  net of interest
owed by the Company for the same period.  As of September 30, 1996,  the Company
recorded $45,856,000 in its oil and gas properties. The acquisition was financed
by borrowings under the Bridge Facility discussed below.

         On September 30, 1996, the Company  entered into a credit facility with
Bankers Trust Company (BTCo) and ING Capital (together the Lenders), providing a
bridge facility in the total amount of $90,000,000,  consisting of a $30,000,000
revolving credit facility,  with $25,000,000 initially available,  a $35,000,000
term loan and a $25,000,000 term loan (the Bridge Facility). The Bridge Facility
is secured by a first priority lien on  substantially  all of the Company's U.S.
assets and matures on October 31, 1997. If borrowings  under the Bridge Facility
have not been  repaid by each of  November  15,  1996 and  January 1, 1997,  the
Company will be obligated to pay the Lenders  additional fees and/or warrants to
purchase common stock of the Company. The agreement limits the Company's debt to
the  Bridge  Facility,  restricts  the  payment of  dividends  other than to the
existing  preferred  stock,  and requires  compliance with minimum  tangible net
worth,  current and interest  coverage  ratios and certain  financial  reporting
requirements.

         The  revolving  credit  facility  and the  $35,000,000  term loan carry
interest at LIBOR plus 2 1/4% and the $25,000,000  term loan carries interest at
the  BTCo's  prime  rate  plus 3%,  increasing  at 1/2% for each  90-day  period
thereafter  to a  maximum  of prime  plus 4 1/2%.  Under an  interest  rate swap
agreement,  the Company pays a fixed rate of 6.15% on  $25,000,000 of borrowings
while the lender under the Bridge Facility will pay a floating rate equal to the
USD-LIBOR-BBA rate for one month maturities to the Company.  Settlements are due
monthly.  The  agreement  terminates  in August 1997 and may be extended  for an
additional  year by the lenders.  On September  30, 1996,  the Company  borrowed
$85,000,000  under the Bridge  Facility  which was used to repay all amounts due
First Union and to finance the purchase of the Wyoming Properties. In connection
with the Bridge  Facility the commodity swap agreement  discussed in Note 15 was
terminated.


<PAGE>


         On November 14, 1996, the Company repaid all amounts  outstanding under
the Bridge  Facility with proceeds from the offering of  $215,000,000  of Senior
Notes described below and entered into an amended and restated credit  agreement
(New Credit Facility).  The New Credit Facility provides for a revolving line of
credit  with an  initial  availability  of $20.0  million,  subject  to  certain
customary  conditions  including a borrowing  base  condition.  No amounts  were
outstanding on September 30, 1996.

         Commitments  available  under the New Credit  Facility  are  subject to
borrowing base redeterminations to be performed semi-annually and, at the option
of each of the  Company  and the  Lenders,  one  additional  time per year.  Any
outstanding  principal  balance in excess of the borrowing  base will be due and
payable in three equal monthly payments after a borrowing base  redetermination.
The borrowing base will be determined in the Agent's sole discretion, subject to
the approval of the Lenders, based on the value of the Company's reserves as set
forth in the reserve report of the Company's  independent  petroleum  engineers,
with consideration given to other assets and liabilities.

         The New Credit Facility has an initial  revolving term of two years and
a reducing  period of three years from the end of the initial  two-year  period.
The  commitment  under the New  Credit  Facility  will be  reduced  during  such
reducing period by eleven equal quarterly reductions.  Quarterly reductions will
equal  8.2% per  quarter  with the  remainder  due at the end of the  three-year
reducing period.

         The applicable  interest rate charged on the outstanding balance of the
New Credit  Facility is based on a facility usage grid. If the borrowings  under
the New Credit  Facility  represent an amount less than or equal to 33.3% of the
available  borrowing  base,  then the  applicable  interest  rate charged on the
outstanding balance will be either (a) an adjusted rate of the London Inter-Bank
Offered Rate  ("LIBOR")  plus 1.25% or (b) the prime rate of the Agent (which is
based on the agent's  published prime rate) plus 9.50%. If the borrowings  under
the New Credit  Facility  represent an amount greater than or equal to 33.3% but
less than 66.7% of the available  borrowing base,  then the applicable  interest
rate on the outstanding principal will be either (a) LIBOR plus 1.75% or (b) the
prime  rate of the Agent  plus  0.50%.  If the  borrowings  under the New Credit
Facility  represent an amount  greater  than or equal to 66.7% of the  available
borrowing base, then the applicable  interest rate on the outstanding  principal
will be either  (a) LIBOR  plus  2.00% or (b) the prime  rate of the Agent  plus
0.50%. LIBOR elections can be made for periods of one, three or six months.

         The New Credit  Facility  contains a number of  covenants  that,  among
other  things,  restrict  the  ability  of  the  Company  to (i)  incur  certain
indebtedness or guarantee obligations,  (ii) prepay other indebtedness including
the Notes, (iii) make investments, loans or advances, (iv) create certain liens,
(v) make certain payments, dividends and distributions,  (vi) merge with or sell
assets to  another  person or  liquidate,  (vii) sell or  discount  receivables,
(viii)  engage  in  certain  intercompany  transactions  and  transactions  with
affiliates,  (ix) change its  business,  (x)  experience a change of control and
(xi) make  amendments  to its charter,  by-laws and other debt  instruments.  In
addition,  under the New Credit Facility, the Company is required to comply with
specified  financial ratios and tests,  including  minimum debt service coverage
ratios, maximum funded debt to EBITDA tests, minimum net worth tests and minimum
working capital tests.



<PAGE>


         The New Credit Facility contains customary events of default, including
nonpayment of principal, interest or fees, violation of covenants, inaccuracy of
representations  or warranties in any material respect,  cross default and cross
acceleration to certain other indebtedness,  bankruptcy,  material judgments and
liabilities and change of control.

         In September  1996,  the Company  entered  into an  agreement  with the
Limited  Partner  and  certain  noteholders  (Noteholders)  of the  Partnership,
pursuant to which the Company agreed to purchase the Limited Partner's  interest
in the Partnership and the Noteholders' notes in the aggregate  principal amount
of $5,920,000  (Notes),  resulting in the Company's  owning,  on a  consolidated
basis,  all  of  the  equity   interests  in  the  Partnership.   The  aggregate
consideration  for  the  purchase  of  the  Limited  Partner's  interest  in the
Partnership  and the Notes is $6,961,000.  The Company will also assume the Bank
Loan which had an outstanding principal balance of approximately  $20,639,000 as
of October 31, 1996, and a commodity price hedge  agreement.  Under the terms of
the agreement,  the Company will be required to receive or make payments to BTCo
and ING Capital based on a  differential  between a fixed and variable price for
crude oil and natural gas through  November  2001 on volumes  ranging from 8,160
barrels of crude oil to 20,000  barrels of crude oil per month and 14,850  MMBTU
of natural gas to 87,406 MMBTU of natural gas per month.  Under this  agreement,
the Company  will receive  fixed prices  ranging from $17.20 per barrel of crude
oil to $18.55 per  barrel of crude oil and  $1.793  per MMBTU of natural  gas to
$1.925 per MMBTU of natural  gas and will make  payments  based on the price for
west Texas intermediate light sweet crude oil on the NYMEX for crude oil and the
Inside FERC, Tennessee Gas Properties Co. Texas price for natural gas. Currently
there is a net unrealized loss of approximately $1.8 million under the commodity
price hedge. On November 14, 1996, the Company closed the transaction.

         As a result, the Company reacquired those interests in the Portilla and
Happy Fields which it previously  owned, as well as the interest in the Portilla
Field  previously  owned by the Pension  Fund.  The Company  will include in its
balance  sheet the amount  previously  removed  from oil and gas  properties  in
connection with the sale of its interest in the Portilla and Happy Fields during
the quarter  ended March 31, 1996,  as well as the amount of the purchase  price
paid for the Pension Fund's interest in the Portilla Field,  and all development
drilling  expenditures  incurred  on the  properties,  less the  amount  of DD&A
related to the  properties  from the  formation of the  Partnership  through the
closing of the transaction.

         In  October  1996,  the  Company  entered  into a letter  of  intent to
purchase  100% of the  outstanding  capital stock of CGGS Canadian Gas Gathering
Systems Inc.  (CGGS) in Calgary,  Canada after the  consummation  of the sale of
CGGS of its Nevis gas processing plant, for approximately  U.S.$85,000,000  plus
the  amount of CGGS's  working  capital  at August  1,  1996,  subject  to price
adjustments.  CGGS owns  producing oil and gas  properties in Western Canada and
adjacent gas gathering and  processing  facilities  as well as  undeveloped  net
acres of leaseholds. On November 14, 1996, the Company, through its wholly owned
subsidiary,  Canadian Abraxas Petroleum  Limited  (Canadian  Abraxas) closed the
transaction  and  immediately  merged CGGS with and into Canadian  Abraxas,  and
Canadian Abraxas,  as the surviving entity,  used the net proceeds from the sale
of the Nevis gas processing plant to retire all of the outstanding debentures of
CGGS.  The  transaction  was  financed  by a portion  of the  proceeds  from the
offering of $215,000,000 of Senior Notes discussed below.



<PAGE>


         On November 14, 1996,  the Company and Canadian  Abraxas  completed the
sale of $215,000,000  aggregate principal amount of Senior Notes due November 1,
2004.  Interest at 11.5% is payable  semi-annually  on May 1 and November 1. The
Notes are general unsecured  obligations of the Company and Canadian Abraxas and
the Company and Canadian Abraxas are joint and several  obligors.  The Notes are
redeemable,  in whole or in part,  at the  option of the  Company  and  Canadian
Abraxas on or after  November  1, 2000,  and any time prior to November 1, 1999,
the Company and Canadian Abraxas may redeem up to 35% of the aggregate principal
amount of the Notes with the cash  proceeds of equity  offerings at a redemption
price of 111.5% of the aggregate  principal  amount of the Notes to be redeemed.
The terms of the Indenture  related to the Notes  provide for certain  financial
covenants which may limit the ability of the Company to incur additional debt.

         In November 1996, the Company  obtained a release of the 50% overriding
royalty interest in the East White Point Field in San Patricia County, Texas and
the Stedman  Island  Field in Nueces  County,  Texas from the  Pension  Fund for
9,300,000 before  adjustment for accrual of net revenue to closing.  The Company
will record the net purchase  price of  approximately  $8,771,000 to its oil and
gas properties.

Estimated Quantities of Proved Oil and Gas Reserves

         The following  table presents the Company's  estimate of its net proved
crude oil and natural gas reserves as of December 31, 1993,  1994, and 1995, and
June 30, 1996. The Company's  management  emphasizes that reserve  estimates are
inherently  imprecise and that estimates of new  discoveries  are more imprecise
than those of producing oil and gas properties.  Accordingly,  the estimates are
expected to change as future information  becomes available.  The estimates have
been prepared by independent petroleum reserve engineers.

     subsidiary,  Cascade, which are not included in the Company's June 30, 1996
     reserve report.

         All proved reserves are located within the continental United States.

         The   significant   downward   revision  in  1995  of  previous  liquid
hydrocarbons  and natural gas was due  principally  to  decreased  estimates  of
recoverable reserves in existing wells related to disappointing drilling results
principally  in the East White Point  field,  resulting in  reclassification  of
proved undeveloped reserves to probable reserves.

         The significant upward revision in 1994 of previous liquid hydrocarbons
and  natural gas was due  principally  to  increased  estimates  of  recoverable
reserves in existing wells as a result of drilling and workover success in 1994,
combined with the completion of geological  engineering studies on several major
fields.

         The  significant  downward  revision  in 1993 of  previous  natural gas
quantities was due principally to the reclassification of natural gas liquids to
liquid  hydrocarbons.  The significant  downward revision of liquid hydrocarbons
was caused by the  approximate  30 percent  decrease  in the price of crude oil,
partially offset by the reclassification of the natural gas liquids.

STANDARDIZED  MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES

         The following disclosures concerning the standardized measure of future
cash flows from proved  crude oil and  natural gas  reserves  are  presented  in
accordance  with  Statement  of  Financial  Accounting  Standards  No.  69.  The
standardized  measure does not purport to represent the fair market value of the
Company's proved crude oil and natural gas reserves.  An estimate of fair market
value  would also take into  account,  among  other  factors,  the  recovery  of
reserves not  classified  as proved,  anticipated  future  changes in prices and
costs, and a discount factor more  representative of the time value of money and
the risks inherent in reserve estimates.

         Under the standardized  measure,  future cash inflows were estimated by
applying  period-end prices at December 31, 1995 and June 30, 1996, adjusted for
fixed and  determinable  escalations,  to the  estimated  future  production  of
year-end proved  reserves.  Future cash inflows were reduced by estimated future
production and  development  costs based on year-end costs to determine  pre-tax
cash  inflows.  Future  income taxes were computed by applying the statutory tax
rate to the excess of  pre-tax  cash  inflows  over the  Company's  basis in the
associated  proved crude oil and natural gas  properties,  less the tax basis of
the  properties.  Operating  loss  carryforwards,  tax  credits,  and  permanent
differences  to the extent  estimated  to be  available  in the future were also
considered in the future income tax calculations,  thereby reducing the expected
tax expense.

         Future net cash inflows after income taxes were discounted  using a 10%
annual discount rate to arrive at the Standardized Measure.

         Set forth below is the Standardized  Measure relating to proved oil and
gas reserves for:

         The net change in prices and  production  costs from prior years in the
Standardized  Measure of discounted  future net cash flows was predominantly due
to an approximate increase in the price of an equivalent barrel of oil of $2.39,
offset by an increase in the production  cost of an equivalent  barrel of oil of
$.70.

To the Board of Directors of
Canadian Gas Gathering Systems Inc.

         We have  audited  the balance  sheets of CGGS  Canadian  Gas  Gathering
Systems  Inc.  as at October 31,  1995 and 1994 and the  statements  of earnings
(loss) and deficit and changes in financial position for the years ended October
31, 1995, 1994 and 1993. These financial  statements are the  responsibility  of
the Company's  management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards  require that we plan and perform an audit to obtain
reasonable  assurance  whether  the  financial  statements  are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management, as well as evaluating the overall financial statement presentation.

         In our opinion,  these  financial  statements  present  fairly,  in all
material respects,  the financial position of the Company as of October 31, 1995
and 1994 and the  results of its  operations  and the  changes in its  financial
position for the years ended October 31, 1995,  1994 and 1993 in accordance with
generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

  (Information as to October 31, 1996 and for the Year Then Ended is Unaudited)


         The Company was incorporated on March 9, 1990 under the Canada Business
Corporations Act. The Company was formed to invest in gas plants,  gas gathering
systems  and  related  gas  reserves  in Canada.  Morrison  Petroleums  Ltd.,  a
shareholder, manages the Company.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         The  financial  statements  are prepared in accordance  with  generally
accepted accounting principles in Canada.

FOREIGN CURRENCY TRANSLATION

         Monetary assets and monetary liabilities are translated at the exchange
rate in effect at the balance sheet date.  Gains and losses on  translation  are
recorded in the  statement of earnings,  except that gains or losses on monetary
liabilities with a fixed or  ascertainable  life are deferred and amortized over
the repayment period.

JOINT VENTURES

         The Company's  exploration and production activities related to oil and
gas  are  substantially  conducted  in  joint  participation  with  others  and,
accordingly,  the accounts reflect only the Company's  proportionate interest in
such activities.

CAPITAL ASSETS

         The Company  follows the full cost method of accounting for exploration
and  development  expenditures  wherein all costs related to the exploration for
and the development of oil and gas reserves are capitalized. These costs include
leasehold acquisition costs, carrying charges of non-producing properties, costs
of drilling and completing wells, and oil and gas production equipment. Proceeds
received  from  the  disposal  of  properties  are  normally   credited  against
accumulated  costs  unless  this  would  result in a  significant  change in the
depletion  rate,  in which case, a gain or loss is computed and reflected in the
earnings statement.

         The  Company  carries  its oil  and  gas  properties  at the  lower  of
capitalized cost and net recoverable  value. Net recoverable value is future net
revenues from proven reserves plus unproven  properties at cost less impairment,
if any, net of the  provision for future site  restoration.  Future net revenues
are determined  using unit prices and production costs in effect at year-end and
include an allowance for future  overhead  costs,  site  restoration,  financing
charges and income taxes that will be incurred in earning these revenues.

         Petroleum  and  natural  gas   properties  are  depleted  and  tangible
production  equipment is depreciated using the  unit-of-production  method based
upon the estimated  proven oil and gas reserves  after  royalties.  Reserves are
converted to common units based on the approximate  equivalent energy content of
each unit of reserves, which results in a conversion ratio of six thousand cubic
feet of gas to one barrel of oil equivalent.

         Processing facilities are depreciated on a straight-line basis over the
estimated useful life of each facility.

PROVISION FOR FUTURE SITE RESTORATION

         Provision is made for future site restoration  costs. This provision is
charged to earnings over the  estimated  life of the proven oil and gas reserves
and processing  facilities  using the unit of production  and the  straight-line
methods respectively, and is included with depletion and depreciation.

ROYALTIES

         Crown,  freehold and overriding  royalties and mineral taxes are net of
Alberta Royalty Tax Credits.

DEFERRED FINANCING COSTS

         The  deferred   financing  costs  are  associated  with  obtaining  the
subscriptions  for units (see Note 2).  These costs were  amortized  evenly over
fifteen  years.

2.  FORMATION AND UNIT SUBSCRIPTIONS

         Under the Unit  Subscription  Agreement,  the investors have subscribed
for units at U.S. $100,000 per unit consisting of U.S. $75,000 of debentures and
U.S.  $25,000 of Class A shares (2,500 Class A shares at a price of U.S. $10 per
share)  in  a  3-to-1  ratio.   The  Company   received   commitments  for  unit
subscriptions  totaling U.S.  $114,700,000  (U.S.  $86,025,000 of debentures and
2,867,500  Class A shares at U.S. $10 per share).  At October 31, 1996, 1995 and
1994 98.12% of the subscriptions were paid for and debentures and shares issued.

         On September 14, 1994, the Board of Directors  approved a resolution to
end any further  acquisitions  by the  investors  and to close out the  investor
obligations.

         At  October  31,  1996,   U.S.   $84,411,829  of  debentures  and  U.S.
$28,137,367 Class A shares were issued and outstanding.

         Under Amendment No. 4 to the Unit Subscription  Agreement dated May 15,
1995,  in 1995  the  Company  is  permitted  to  expend  all of its  funds  from
operations  after debt  servicing and all  applicable  corporate tax, on capital
enhancements,  repairs and maintenance. In 1996 and subsequent years, subject to
approval by eighty  percent of all  shareholders,  the Company is  permitted  to
expend  two-thirds  of its funds from  operations  after debt  servicing and all
applicable corporate tax, on capital enhancements, repairs and maintenance.

              as a hedge, are included in income  currently  instead of deferred
              and amortized over the lives of such long term liabilities.

         (b)  The  Company  has  applied   Statement  of  Financial   Accounting
              Standards  Number 109  "Accounting  for Income Taxes" ("SFAS 109")
              effective  November  1, 1992.  SFAS 109  requires  the  Company to
              account for income  taxes using the  liability  method for US GAAP
              purposes.  There was no  cumulative  effect  or effect on  current
              results as a consequence of adopting SFAS 109.

                          Independent Auditors' Report



To the Board of Directors of
   Enserch Exploration, Inc.

         We have  audited the  accompanying  statements  of revenues  and direct
operating  expenses of Enserch  Exploration,  Inc.'s Wamsutter Area Package (the
"Package")  (see Note 1) to be sold to  Abraxas  Petroleum  Corporation  for the
years ended December 31, 1995,  1994, and 1993.  These financial  statements are
the responsibility of the management of Enserch  Exploration,  Inc., as operator
of the  properties.  Our  responsibility  is to  express  an  opinion  on  these
financial statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         The accompanying  statements of revenues and direct operating  expenses
reflect the revenues and direct operating  expenses  attributable to the Package
as described in Note 1 to the financial  statements and are not intended to be a
complete presentation of the revenues and expenses of the Package.

         In our opinion,  the accompanying  financial statements present fairly,
in all material  respects,  the revenues  and direct  operating  expenses of the
Package as described in Note 1 for the years ended December 31, 1995,  1994, and
1993, in accordance with generally accepted accounting principles.

                       NOTES TO STATEMENTS OF REVENUES AND
                            DIRECT OPERATING EXPENSES


1.  THE PROPERTIES

         The accompanying statements represent the revenues and direct operating
expenses attributable to the net interest in Enserch Exploration, Inc.'s ("EEX")
Wamsutter Area Package  producing wells and certain  non-producing  leases to be
sold to Abraxas Petroleum Corporation ("Abraxas"). The properties are located in
Sweetwater  and Canton County,  Wyoming.  EEX acquired the properties on June 8,
1995 when it purchased all of the capital stock of Dalen Corporation.  Effective
January 1, 1996, Dalen Corporation was merged into EEX.

         Historical financial statements reflecting financial position,  results
of  operations  and  cash  flows  required  by  generally  accepted   accounting
principles are not presented,  as such information is neither readily  available
on an individual  property  basis nor  meaningful  for the  properties  acquired
because the entire acquisition cost is being assigned to oil and gas properties.
Accordingly,  these  statements  of revenues and direct  operating  expenses are
presented  in lieu of the  financial  statements  required  under  Rule  3-05 of
Securities and Exchange Commission Regulation S-X.

         The accompanying  statements of revenues and direct operating  expenses
represent EEX's net working interest in the properties to be acquired by Abraxas
and are  presented on the full cost accrual basis of  accounting.  Depreciation,
depletion  and  amortization,  allocated  general  and  administrative  expense,
interest  expense and income,  and income taxes have been  excluded  because the
property  interests  acquired  represent  only a portion of a  business  and the
expenses incurred are not necessarily  indicative of the expenses to be incurred
by Abraxas.

2.  CONTINGENT LIABILITIES

         Given the nature of the  properties  acquired and as  stipulated in the
purchase  agreement,  Abraxas  is  subject  to loss  contingencies  pursuant  to
existing or expected  environmental laws,  regulations,  and losses covering the
acquired properties.

3.  OIL AND GAS RESERVES (UNAUDITED)

         The following table of estimated proved and proved  developed  reserves
of oil and gas  related  to the  Wamsutter  Area  Package  properties  has  been

independent petroleum consultants.

         January  1,  1995.  Prior to l994,  gas was not  processed  to  extract
         natural gas liquids.

4. STANDARDIZED MEASURE (UNAUDITED)

         Discounted future net cash flows relating to proved gas and oil reserve
quantities  (unaudited)  have been prepared using  estimated  future  production
rates and associated production and development costs.  Continuation of economic
conditions  existing  at  the  balance  sheet  date  was  assumed.  Accordingly,
estimated  future net cash flows were computed by applying  prices and contracts
in effect at period end to  estimated  future  production  of proved gas and oil
reserve,   estimating  future   expenditures  to  develop  proved  reserves  and
estimating  costs to produce the proved  reserves based on average costs for the
period.  Average  prices used in the  computations  were: Gas (per Mcf) $2.08 in
1995, $1.45 in 1994 and $2.40 in 1993; Oil (per barrel) $11.17 in 1995, $7.22 in
1994 and $13.52 in 1993.

         Because  reserve  estimates  are  imprecise  and  changes  in the other
variables are unpredictable,  the standardized  measure should be interpreted as
indicative of the order of magnitude only and not as precise amounts.

                                                  1995       1994       1993

                         Report of Independent Auditors



Board of Directors
Abraxas Petroleum Corporation

We have audited the accompanying statements of combined oil and gas revenues and
direct operating  expenses of the Certain  Overriding  Royalty  Interests in the
Portilla Field Acquired by Abraxas Petroleum Corporation (Abraxas) for the years
ended December 31, 1994 and 1995.  These  statements are the  responsibility  of
Abraxas'  management.  Our  responsibility  is to  express  an  opinion  on  the
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  statements  of  combined  oil and gas
revenues and direct  operating  expenses are free of material  misstatement.  An
audit includes examining,  on a test basis,  evidence supporting the amounts and
disclosures  in the  statements  of  combined  oil and gas  revenues  and direct
operating  expenses.  An audit also  includes  assessing the basis of accounting
used and  significant  estimates made by  management,  as well as evaluating the
overall  presentation  of  statements.  We  believe  that our  audits  provide a
reasonable basis for our opinion.

The  accompanying  statements  of  combined  oil and  gas  revenues  and  direct
operating expenses were prepared for the purpose of complying with the rules and
regulations of the  Securities  and Exchange  Commission as described in Note 1,
are not  intended  to be a complete  presentation  of the  combined  oil and gas
revenues and expenses of Certain  Overriding  Royalty  Interests in the Portilla
Field Acquired by Abraxas.

In our opinion, the statements referred to above present fairly, in all material
respects,  the combined oil and gas  revenues and direct  operating  expenses of
Certain  Overriding  Royalty Interests in the Portilla Field Acquired by Abraxas
for the years ended  December  31, 1994 and 1995 in  conformity  with  generally
accepted accounting principles.

           CERTAIN OVERRIDING ROYALTY INTERESTS IN THE PORTILLA FIELD
                    ACQUIRED BY ABRAXAS PETROLEUM CORPORATION

              NOTES TO STATEMENTS OF COMBINED OIL AND GAS REVENUES
                          AND DIRECT OPERATING EXPENSES

                     Years Ended December 31, 1994 and 1995

(Information  as to the  Nine  Months  Ended  September  30,  1995  and  1996 is
Unaudited)


1.  BASIS OF PRESENTATION

         The accompanying  statement of combined oil and gas revenues and direct
operating  expenses  represents  the results from certain oil and gas  producing
properties  located  in the  Portilla  Field,  San  Patricia  County,  Texas  --
(Properties)  which were previously  owned by the Commingled  Pension Trust Fund
(Petroleum  II) (the Pension Fund) which were  acquired in  connection  with the
acquisition by Abraxas  Petroleum  Corporation  (Abraxas).  Abraxas acquired the
remaining 75% partnership  interest in Portilla-1996,  L.P., the limited partner
of which  acquired the above  interests  from the Pension Fund on March 21, 1996
and contributed such interest to the Partnership.

         Full historical  financial  statements  reflecting  financial position,
results of operations,  and cash flows required by generally accepted accounting
principles are not presented, as such information is not readily available on an
individual property basis nor meaningful for the properties acquired because the
entire   acquisition   cost  is  being  assigned  to  oil  and  gas  properties.
Accordingly,  these  statements  of  combined  oil and gas  revenues  and direct
operating  expenses are presented in lieu of the financial  statements  required
under Rule 3-05 of Regulation S-X of the Securities and Exchange Commission.

         The accompanying statements of combined oil and gas revenues and direct
operating  expenses  represent  the  net  overriding  royalty  interests  in the
Properties  to be acquired by Abraxas and are  presented on the accrual basis of
accounting. Depreciation, depletion and amortization, general and administrative
expenses,  interest  expense,  and  federal  and state  income  taxes  have been
excluded because the property  interests  acquired represent only a portion of a
business  and the  expenses  incurred  are  not  necessarily  indicative  of the
expenses to be incurred by Abraxas.

         The  unaudited  statements  of combined oil and gas revenues and direct
operating  expenses  for the  nine  months  ended  September  30,  1995 and 1996
include, in the opinion of management,  all material adjustments  (consisting of
only  normal  recurring  adjustments)  necessary  for a fair  presentation.  The
results  of the nine  months  ended  September  30,  1996,  are not  necessarily
indicative of the results to be expected for the full year.

STANDARDIZED  MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES

         The following disclosures concerning the standardized measure of future
cash flows from proved  crude oil and  natural gas  reserves  are  presented  in
accordance  with  Statement  of  Financial  Accounting  Standards  No.  69.  The
standardized  measure does not purport to represent the fair market value of the
Properties'  proved  crude oil and  natural  gas  reserves.  An estimate of fair
market value would also take into account,  among other factors, the recovery of
reserves not  classified  as proved,  anticipated  future  changes in prices and
costs and a discount factor more  representative  of the time value of money and
the risks inherent in reserve estimates.

         Under the standardized  measure,  future cash inflows were estimated by
applying  prices at December 31, 1995 and June 30, 1996 to the estimated  future
production of period-end  proved  reserves.  Future cash inflows were reduced by
estimated future  production and development  costs based on period-end costs to
determine  pre-tax cash inflows.  The  Properties  are not, nor is the Owner,  a
separate tax paying entity. Accordingly,  the standardized measure of discounted
future net cash flows from proved  reserves is  presented  before  deduction  of
federal income taxes.

         Future net cash inflows  were  discounted  using a 10% annual  discount
rate to arrive at the Standardized Measure.

                               September 30, 1996


1. ORGANIZATION

ORGANIZATION AND OPERATIONS

         Canadian Abraxas Petroleum  Limited, a Canadian  Corporation  (Canadian
Abraxas),  was  capitalized by Abraxas  Petroleum  Corporation for the principal
purpose of acquiring 100% of the outstanding  capital stock of CGGS Canadian Gas
Gathering Systems,  Inc. (CGGS), after the consummation of the sale of the Nevis
Plant. CGGS owns producing properties in western Canada, consisting primarily of
natural gas reserves,  natural gas gathering systems, and processing facilities.
Canadian  Abraxas has  conducted  no business  and has no employees or operating
history as of September 30, 1996. Due to the absence of business  activity as of
September 30, 1996, no statement of operations or cash flows is presented.

         On November 14, 1996, Abraxas Petroleum Corporation, through its wholly
owned  subsidiary,  Canadian  Abraxas,  closed  the  acquisition  of CGGS with a
portion of the proceeds  from the issuance of  $215,000,000  of Senior Notes due
2004 (Notes). Abraxas Petroleum Corporation and Canadian Abraxas are jointly and
severally  liable for all  obligations  under the Notes.  In connection with the
close of the transaction, Canadian Abraxas incurred a liability of approximately
$82,000,000 of the $215,000,000 liability.  Additionally, in connection with the
close of the  transaction,  CGGS was  immediately  merged with and into Canadian
Abraxas,  and Canadian Abraxas,  as the surviving entity,  used the net proceeds
from the sale of the Nevis gas processing plant to retire all of the outstanding
debentures of CGGS.

Item 20. Indemnification of Directors and Officers

         Abraxas' Articles of Incorporation  contain a provision that eliminates
the personal  monetary  liability  of directors  and officers to Abraxas and its
stockholders for a breach of fiduciary  duties to the extent  currently  allowed
under the Nevada General  Corporation Law (the "Nevada Statute").  In respect of
Canadian Abraxas,  the Canada Business  Corporation Act ("CBCA") does not permit
any such  limitations  of a  director's  liability.  If a director or officer of
Abraxas  were  to  breach  his  fiduciary   duties,   neither  Abraxas  nor  its
stockholders  could  recover  monetary  damages,  and the only  course of action
available  to Abraxas'  stockholders  would be  equitable  remedies,  such as an
action to enjoin or rescind a transaction  involving a breach of fiduciary duty.
To the extent  certain  claims  against  directors  or  officers  are limited to
equitable  remedies,  this provision of Abraxas'  Articles of Incorporation  may
reduce the likelihood of derivative  litigation and may discourage  stockholders
or  management  from  initiating  litigation  against  directors or officers for
breach  of  their  duty of care.  Additionally,  equitable  remedies  may not be
effective in many  situations.  If a stockholder's  only remedy is to enjoin the
completion of the Board of Director's  action,  this remedy would be ineffective
if the stockholder did not become aware of a transaction or event until after it
had been completed.  In such a situation,  it is possible that the  stockholders
and the  Company  would  have no  effective  remedy  against  the  directors  or
officers.

         Liability  for  monetary  damages has not been  eliminated  for acts or
omissions which involve intentional misconduct,  fraud or a knowing violation of
law or payment of an improper  dividend in  violation  of section  78.300 of the
Nevada  Statute.  The  limitation of liability  also does not eliminate or limit
director liability arising in connection with causes of action brought under the
Federal securities laws.

         The Nevada Statute permits a corporation to indemnify  certain persons,
including officers and directors, who are (or are threatened to be made) parties
against  all  expenses  (including  attorneys'  fees)  actually  and  reasonably
incurred by, or imposed upon,  him in  connection  with the defense by reason of
his being or having  been a director or officer if he acted in good faith and in
a manner  which  he  reasonably  believed  to be in or not  opposed  to the best
interests  of the  corporation  and,  with  respect  to any  criminal  action or
proceeding,  had no reasonable cause to believe his conduct was unlawful, except
where he has been  adjudged  by a court of  competent  jurisdiction  (and  after
exhaustion  of all  appeals)  to be  liable  for  gross  negligence  or  willful
misconduct  in  the   performance  of  duty.  The  Bylaws  of  Abraxas   provide
indemnification to the same extent allowed pursuant to the foregoing  provisions
of the Nevada Statute.

         Nevada  corporations also are authorized to obtain insurance to protect
officers and directors from certain liabilities,  including  liabilities against
which  the  corporation  cannot  indemnify  its  directors  and  officers.  CBCA
corporations  are permitted to obtain such insurance also,  accept for liability
relating  to the  failure to act  honestly  and in good faith with a view to the
best  interests of the  corporation.  Abraxas  currently  has a  directors'  and
officers'  liability  insurance  policy  in effect  providing  $3.0  million  in
coverage  and an  additional  $1.0  million in coverage  for certain  employment
related claims.

         Abraxas  has  entered  into  indemnity  agreements  with  each  of  its
directors and officers.  These  agreements  provide for  indemnification  to the
extent permitted by the Nevada Statute.

         Under the CBCA,  except  in  respect  of an action by or on behalf of a
corporation  or a  body  corporate  to  procure  a  judgment  in  its  favor,  a
corporation may indemnify a director or officer, a former director or officer or
a person who acts or acted at the corporation's request as a director or officer
of a  body  corporate  of  which  the  corporation  is or was a  shareholder  or
creditor,  and his or her  heirs and legal  representatives  (an  "Indemnifiable
Person"),  against all costs, charges and expenses,  including an amount paid to
settle an action or satisfy a  judgment,  reasonably  incurred  by him or her in
respect of any civil,  criminal or administrative  action or proceeding to which
he or she is made a party by  reason  of  being or  having  been a  director  or
officer  of such  corporation  or such body  corporate,  if: (a) he or she acted
honestly  and  in  good  faith  with  a  view  to the  best  interests  of  such
corporation;  and (b) in the case of a  criminal  or  administrative  action  or
proceeding  that is enforced  by a monetary  penalty,  he or she had  reasonable
grounds for believing  that his or her conduct was  substantially  successful on
the  merits in his or her  defense of the action or  proceeding,  fulfilled  the
conditions set out in (a) and (b),  above and is fairly and reasonably  entitled
to indemnity. A corporation may, with the approval of a court, also indemnify an
Indemnifiable  Person in respect of an action by or on behalf of the corporation
or body  corporate  to procure a judgment in its favor,  to which such person is
made a party by reason of being or having  been a director  or an officer of the
corporation or body  corporate,  if he or she fulfills the conditions set out in
(a) and (b), above. The Canadian Abraxas Bylaws provide for  indemnification  of
directors and officers to the fullest extent authorized by the CBCA.

ITEM 22. UNDERTAKINGS

         A. Each of the undersigned  registrants hereby undertakes to respond to
requests for  information  that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b),  11, or 13 of this Form,  within one business day of
receipt of such request,  and to send the incorporated  documents by first class
mail or other equally  prompt  means.  This  includes  information  contained in
documents filed subsequent to the effective date of the  Registration  Statement
through the date of responding to the request.

         B. Each of the  undersigned  registrants  hereby  undertakes  that, for
purposes of determining  any liability  under the  Securities Act of 1933,  each
filing of the  registrant's  annual report  pursuant to Section 13(a) or Section
15(d) of the Securities  Exchange Act of 1934 that is  incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         C.  Insofar  as  indemnification  for  liabilities  arising  under  the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of each of the  registrants  pursuant to the  foregoing  provisions,  or
otherwise,  the  registrants  have  been  advised  that  in the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is,  therefore,  unenforceable.  In the event that a
claim for  indemnification  against such liabilities  (other than the payment by
the  registrants  of  expenses  incurred  or  paid  by a  director,  officer  or
controlling person in the successful defense of any action, suit or proceedings)
is asserted by such director,  officer or controlling  person in connection with
the securities being registered,  the registrants will, unless in the opinion of
their counsel the matter has been settled by controlling precedent,  submit to a
court of appropriate  jurisdiction the question whether such  indemnification by
either of them is  against  public  policy as  expressed  in the Act and will be
governed by the final adjudication of such issue.

         D. Each of the undersigned  registrants  hereby undertakes to supply by
means of a  post-effective  amendment all information  concerning a transaction,
and the company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                                  SCHEDULE "A"

                  The authorized  capital of the Corporation shall consist of an
unlimited  number of Common  Shares and an unlimited  number of First  Preferred
Shares which shares shall have the following  rights,  privileges,  restrictions
and conditions:

                  COMMON SHARES

1.                Voting Rights

                  The holders of Common  Shares  shall be entitled to notice of,
to attend and to one vote per share held at any meeting the shareholders' of the
Corporation  (other  than  meetings  of a  class  or  series  of  shares  of the
Corporation other than the Common Shares as such);

2.                Dividend

                  The  holders of Common  Shares  shall be  entitled  to receive
dividends as and when declared by the Board of Directors of the  Corporation  on
the Common Shares as a class,  subject to prior satisfaction of all preferential
rights to  dividends  attached  to all shares of other  classes of shares of the
Corporation  ranking in priority to the Common  Shares in respect of  dividends;
and

3.                Liquidations

                  The holders of Common Shares shall be entitled in the event of
any liquidation, dissolution or winding-up of the Corporation, whether voluntary
or involuntary, or any other distribution of the assets of the Corporation among
its shareholders for the purpose of winding-up its affairs, and subject to prior
satisfaction  of all  preferential  rights to return of capital  on  dissolution
attached to all shares of other classes of shares of the Corporation  ranking in
priority to the Common Shares in respect of return of capital on dissolution, to
share rateably, together with the holders of shares of any other class of shares
of the  Corporation  ranking equally with the Common Shares in respect of return
of capital, in such assets of the Corporation as are available for distribution.


                  FIRST PREFERRED SHARES

1.                Voting Rights

                  The holders of the First Preferred Shares shall be entitled to
receive  notice  of,  to attend  and to vote one (1) vote per share  held at any
meeting of the  shareholders of the Corporation  (other than meetings of a class
or series of shares of the Corporation  other than the First Preferred Shares as
such).


2.                Dividends

                  The holders of the First Preferred Shares shall be entitled to
receive if, as and when  declared by the Board of Directors  of the  Corporation
out of the monies of the  Corporation  applicable  to the payment of  dividends,
such  dividends in any financial  year as the Board of Directors in its absolute
discretion  may by  resolution  determine,  and the  directors  may,  subject to
Section 11 hereof  declare  dividends  on any other class of share at  different
times or at the same time in different  amounts than  dividends  declared on the
First Preferred Shares.

3.                Redemption

3.1 Subject to applicable law, the  Corporation  shall have the right to redeem,
at any time all,  or from time to time any part of, the then  outstanding  First
Preferred  Shares at a price per share equal to the  Redemption  Value.  For the
purpose  of  sections  3, 4, 5, 6 and 10,  the  Redemption  Value of each  First
Preferred  Share  shall be an  amount  equal to (i) the  monetary  consideration
received by the Corporation upon the issuance of such share  (denominated in the
currency in which such consideration was paid to the Corporation), if such share
has been issued for money;  or (ii) the fair market  value of the  consideration
received by the Corporation  (including,  without limitation,  shares of another
class of the  Corporation)  upon the  issuance of each share,  if such share has
been issued for a  consideration  other than money together with all accrued and
unpaid  dividends  thereon up to the date fixed for redemption (the whole amount
being herein referred to as the "Redemption Price").

3.2 In case only a part of the then outstanding First Preferred Shares is at any
time to be  redeemed,  the shares so to be redeemed  shall be redeemed pro rata,
excluding  fractions,  from the holdings of all  shareholders of First Preferred
Shares or in such other manner as the Board of Directors deems reasonable.

3.3 On any  redemption  of First  Preferred  Shares  under  this  Section 3, the
Corporation  shall,  subject to the unanimous waiver of notice by the registered
holders thereof, give at least 21 days before the date fixed for redemption (the
"Redemption  Date"),  a notice in writing of the intention of the Corporation to
redeem First Preferred  Shares (the  "Redemption  Notice") to each person who at
the date of giving  of such  notice is a  registered  holder of First  Preferred
Shares to be redeemed.  The Redemption  Notice shall set out the  calculation of
the Redemption  Price,  the Redemption  Date and, unless all the First Preferred
Shares held by the holder to whom it is addressed are to be redeemed, the number
of such shares so held which are to be redeemed.

3.4  The  Redemption  Price  (less  any  tax  required  to be  withheld  by  the
Corporation) shall be paid by cheque payable in lawful money of Canada at par at
any branch in Alberta of the Corporation's bankers for the time being or by such
other reasonable means as the Corporation  deems desirable.  The mailing of such
cheque from the  Corporation's  registered  office, or the payment by such other
reasonable means as the Corporation deems desirable, on or before the Redemption
Date shall be deemed to be payment of the Redemption Price  represented  thereby
on the  Redemption  Date  unless  the  cheque is not paid upon  presentation  or
payment by such other means is not received.  Notwithstanding the foregoing, the
Corporation  shall be  entitled  to require at any time,  and from time to time,
that the Redemption Price be paid to holders of First Preferred Shares only upon
presentation and surrender at the registered office of the Corporation or at any
other  place or places in Alberta  designated  by the  Redemption  Notice of the
certificate or certificates for such First Preferred Shares to be redeemed.

3.5 If a part only of the First Preferred Shares  represented by any certificate
are to be redeemed,  a new  certificate  for the balance  shall be issued at the
expense of the Corporation.

3.6 At any time after the Redemption Notice is given, the Corporation shall have
the right to deposit the Redemption  Price of any or all First Preferred  Shares
to be redeemed  with any  chartered  bank or banks or with any trust  company or
trust  companies in Alberta named for such purpose in the  Redemption  Notice to
the credit of a special account or accounts in trust for the respective  holders
of such shares,  to be paid to them  respectively upon surrender to such bank or
banks or trust company or trust  companies of the  certificate  or  certificates
representing  the same.  Upon such  deposit or  deposits  being made or upon the
Redemption Date, whichever is later, the shares in respect of which such deposit
has been  made  shall be and be  deemed  to be  redeemed  and the  rights of the
holders of such shares  shall be limited to  receiving,  without  interest,  the
proportion of the amount so deposited applicable to their respective shares. Any
interest allowed on such deposit or deposits shall accrue to the Corporation.

3.7 From and after the Redemption  Date, the First  Preferred  Shares called for
redemption shall cease to be entitled to dividends and the holders thereof shall
not be entitled to exercise any of the rights of shareholders in respect thereof
unless  payment  of  the  Redemption  Price  shall  not  be  duly  made  by  the
Corporation,  in which event the rights of such holders shall remain  unaffected
until the Redemption Price has been paid in full.

3.8 First  Preferred  Shares  which are  redeemed  or deemed to be  redeemed  in
accordance  with this  Section 3 shall,  subject to  applicable  law,  be and be
deemed to be returned to the authorized but unissued capital of the Corporation.

any time or times,  to require  the  Corporation  to redeem at a price per share
equal to the  Redemption  Value  thereof,  together  with all accrued and unpaid
dividends thereof up to the Retraction Date (as hereinafter  defined) (the whole
amount being herein referred to as the "Retraction  Price"),  all or any of such
shares  which  are  registered  in  such  holder's  name  on  the  books  of the
Corporation.  Such right shall be exercised by the registered  holder delivering
to the Corporation at its registered office:

a.        a notice in writing executed by such holder (the "Retraction  Notice")

          i. the number of First  Preferred  Shares which such holder  wishes to
have redeemed by the Corporation; and

          ii.  the  business  day on  which  such  holder  wishes  to  have  the
Corporation redeem such shares (the "Retraction  Date"),  which day shall not be
less  than 21 days  from the date  the  Retraction  Notice  is  received  by the
Corporation; and

b.        a share certificate or certificates representing such shares, duly
endorsed, which such holder wishes to have the Corporation redeem.

4.2       Upon receipt of the documents set out in Section 4.1, the  Corporation
shall, on the Retraction Date, pay the Retraction Price for each First Preferred
Share to be redeemed (less any tax required to be withheld by the  Corporation).
Such payment shall be made by cheque payable in lawful money of Canada at par at
any branch in Alberta of the  Corporation's  bankers  for the time  being.  Such
shares  shall be  redeemed  on the  Retraction  Date,  and from  and  after  the
Retraction  Date,  the holder of such shares  being  redeemed  shall cease to be
entitled to  dividends,  and shall not be  entitled  to  exercise  any rights in
respect  thereof,  unless  payment  of the  Retraction  Price is not made on the
Retraction  Date,  in which  event  the  rights  of such  holders  shall  remain
unaffected until the Retraction Price has been paid in full.


          
4.3      First  Preferred  Shares which are retracted or deemed to be retracted
in accordance  with this Section 4 shall,  subject to applicable  law, be and be
deemed to be returned to the authorized but unissued capital of the Corporation.
 

          
5.                Purchase for Cancellation

5.1      In addition to its right to redeem First Preferred  Shares as provided
in Section 3, the Corporation may at any time or times purchase for cancellation
the whole or any part of the outstanding  First Preferred  Shares at a price per
share equal to the Redemption Value thereof.

          

5.2      First  Preferred  Shares  purchased in accordance  with this Section 5
shall,  subject to the  applicable  law,  be and be deemed to be returned to the
authorized but unissued capital of the Corporation.

          

6.                Liquidation

6.1      In the event of the  liquidation,  dissolution  or  winding  up of the
Corporation or other  distribution  of the assets of the  Corporation  among its
shareholders  for the  purpose of winding up its  affairs,  the holders of First
Preferred  Shares shall be entitled to receive the  Redemption  Value per share,
together  with  any  accrued  and  unpaid  dividends  thereof  up to the date of
commencement  of  any  such  liquidation,   dissolution,  winding  up  or  other
distribution of the assets of the Corporation,  to be paid all such money before
any money shall be paid or property or assets  distributed to the holders of any
Common Shares or other shares in the capital of the  Corporation  ranking junior
to the First Preferred Shares with respect to return of capital.

          

6.2      After  payment  to the  holders of the First  Preferred  Shares of the
amounts so payable to them in  accordance  with this  Section 6, the  holders of
First  Preferred   Shares  shall  not  be  entitled  to  share  in  any  further
distribution of the property or assets of the Corporation.

          

7.                Amendments

                  The rights,  privileges,  restrictions and conditions attached
to the First Preferred Shares may be amended,  modified,  suspended,  altered or
repealed  but only if  consented  to, or  approved  by, the holders of the First
Preferred Shares in the manner hereinafter  specified and in accordance with any
requirements of applicable law.

8.                Creation of Additional Shares

                  No class of shares  may be  created  ranking  as to capital or
dividends in priority to or on a parity with the First Preferred  Shares without
the  consent or approval  of the  holders of the First  Preferred  Shares in the
manner  hereinafter  specified  and  in  accordance  with  any  requirements  of
applicable law.

9.                Approval by Holders of First Preferred Shares

                  For the  purpose of  Sections 7 and 8, any consent or approval
given by the  holders  of First  Preferred  Shares  shall be deemed to have been
sufficiently  given if it shall have been given in writing by all the holders of
the outstanding First Preferred Shares or by a resolution passed at a meeting of
holders of First  Preferred  Shares  duly  called and held upon not less than 21
days'  notice in writing to the  holders at which the holders of at least 50% of
the outstanding  First Preferred  Shares are present or are represented by proxy
and carried by the  affirmative  vote of not less than  two-thirds  of the votes
cast at such  meeting.  On every ballot cast at every  meeting of the holders of
the First  Preferred  Shares,  every holder of a First  Preferred Share shall be
entitled to one (1) vote in respect of each First Preferred Share held.  Subject
to the  foregoing,  the  formalities  to be observed in respect of the giving or
waiving  of notice of any such  meeting or  adjourned  meeting  and the  conduct
thereof  shall be those  from  time to time  prescribed  in the  by-laws  of the
Corporation.

10.               Adjustment

10.1              The  fair   market   value  of  any   property   received   as
consideration for the issuance of any First Preferred Shares shall be determined
initially by the directors of the Corporation;  but if it should subsequently be
ascertained  that the fair market value of the said  property is greater than or
less than such determined value whether by:
                 

a.       a tribunal or court of competent jurisdiction;

b.       agreement  between  the  Corporation  and the  Department  of National
Revenue; or         

c.       agreement  between  the  Corporation  and  the  holders  of the  First
Preferred  Shares;  then subject to the Canada  Business  Corporations  Act (the
"Act"), the Board of Directors, on behalf of the Corporation,  shall ensure that
the  Redemption  Value be increased or decreased  accordingly.  This  adjustment
shall be made  retroactively  effective  as of the date of issuance of the First
Preferred Shares.

          

10.2              If an adjustment is made to the Redemption  Value pursuant to
Section 10.1,  and if the Board of Directors of the  Corporation  decide that an
adjustment to the stated capital of the First Preferred Shares is required, then
subject to the provisions of the Act, the stated capital of the First  Preferred
Shares  shall be  adjusted  retroactively  to the date of  issuance of the First
Preferred  Shares to the  amount  determined  by the Board of  Directors  of the
Corporation.

                   

10.3              If dividends are paid on the First  Preferred  Shares between
the date of issue and the actual date of any adjustment  provided for in Section
10.1, then forthwith upon any adjustment being made pursuant to Section 10.1, an
amount equal to the difference  between the amount of dividend actually received
and the amount of  dividend  which would have been  received if the  adjustment,
pursuant to Section 10.1,  had actually been made at the date of issuance of the
First Preferred Shares shall be paid to the Corporation by the recipients of the
dividend or to the  recipients of the dividend by the  Corporation,  as the case
may be.

                   

10.4              If any First  Preferred  Shares are  redeemed,  retracted  or
purchased  pursuant  to any of  Sections 3, 4 or 5 before the actual date of any
adjustment  provided for in Section 10.1,  then  forthwith  upon any  adjustment
being made pursuant to Section 10.1, an amount equal to the  difference  between
the price actually paid on the  redemption,  retraction or purchase of the First
Preferred  Shares and the price  which  would have been paid on the  redemption,
retraction or purchase of the redeemed,  retracted or purchased  First Preferred
Shares if the adjustment  pursuant to Section 10.1 had actually been made at the
date of issuance of the First Preferred  Shares shall be paid by the Corporation
or  the  person  whose  First  Preferred  Shares  were  redeemed,  retracted  or
purchased, as the case may be.

                   

11.               Restriction on Distributions

                  No  distribution  shall be made to the  holders  of any of the
Common Shares or any shares of any class ranking  junior to the First  Preferred
Shares, if such distribution would result in the Corporation having insufficient
net assets to redeem or purchase the First Preferred Shares. For the purposes of
this section,

a.       "net assets" of the Corporation  means the amount for which the assets
of the  Corporation  could realize in cash at that time less the  liabilities of
the Corporation at that time; and

b.       "distribution" means any declaration, payment or distribution to or to
the  account  of any  holders of any Common  Shares of the  Corporation,  now or
hereafter outstanding by way of:

          

          (1) dividends in cash or specie, except dividends payable in shares of
any class of share of the Corporation; or

         (2) purchase,  redemption or other retirement of any outstanding shares
except when such purchase, redemption or other retirement is paid for out of the
proceeds of a fresh issue of shares made for that purpose.

shall be transacted under such agreements, instructions and delegations of power
as the board may from time to time prescribe or authorize.

                            EXECUTION OF INSTRUMENTS

             3.01        Authorized Signing Officers

                         Unless  otherwise  authorized by the directors,  deeds,
transfers,   assignments,   contracts,   obligations,   certificates  and  other
instruments  may be  signed  on  behalf  of the  Corporation  by any  two of the
president,  chairman of the board,  managing director,  any vice-president,  any
director,  secretary,  treasurer,  any  assistant  secretary  or  any  assistant
treasurer  or any other office  created by by-law or by the board.  In addition,
the board may from time to time direct the manner in which the person or persons
by whom  any  particular  instrument  or class  of  instruments  may or shall be
signed.  Any signing  officer  may affix the  corporate  seal to any  instrument
requiring the same,  but no instrument is invalid  merely  because the corporate
seal is not affixed thereto.

                         All cheques,  drafts or orders for the payment of money

                                    DIRECTORS

             4.01        Number

                         The board shall  consist of such number of directors as
is fixed by the articles, or where the articles specify a variable number, shall
consist of such  number of  directors  as is not less than the  minimum nor more
than the maximum  number of  directors  provided in the articles and as shall be
fixed from time to time by resolution of the shareholders.

             4.02        Election and Term

                         Subject  to the  articles  or a  unanimous  shareholder
agreement,  the election of directors shall take place at each annual meeting of
shareholders  and all of the  directors  then in office,  unless  elected  for a
longer period of time (not to exceed the close of the third (3rd) annual meeting
of shareholders  following election),  shall retire but, if qualified,  shall be
eligible  for  re-election.  The number of  directors  to be elected at any such
meeting shall, subject to the articles or a unanimous shareholder agreement,  be
the number of directors then in office,  or the number of directors  whose terms
of office expire at the meeting,  as the case may be, except that, if cumulative
voting is not required by the articles and the articles  otherwise  permit,  the
shareholders  may  resolve to elect some other  number of  directors.  Where the
shareholders  adopt an  amendment  to the  articles  to  increase  the number or
minimum number of directors,  the shareholders may, at the meeting at which they
adopt the amendment,  elect the additional number of directors authorized by the
amendment.  If an  election of  directors  is not held at the proper  time,  the
incumbent directors shall continue in office until their successors are elected.
If the  articles  provide  for  cumulative  voting,  each  director  elected  by
shareholders  (but not directors elected or appointed by creditors or employees)
ceases to hold  office at the annual  meeting and each  shareholder  entitled to
vote at an election of  directors  has the right to cast a number of votes equal
to the number of votes  attached  to the shares  held by him  multiplied  by the
number of  directors  he is entitled to vote for, and he may cast all such votes
in favor of one candidate or distribute them among the candidates in any manner.
If he has voted for more than one candidate without  specifying the distribution
among such candidate, he shall be deemed to have divided his votes equally among
the candidates for whom he voted.

             4.03        Removal of Directors

                         Subject to the Act and the articles,  the  shareholders
may by ordinary  resolution passed at a special meeting remove any director from
office,  except a director  elected by employees  or  creditors  pursuant to the
articles or a unanimous shareholder  agreement,  and the vacancy created by such
removal may be filled at the same meeting, failing which it may be filled by the
board. Provided, however, that if the articles provide for cumulative voting, no
director shall be removed  pursuant to this section where the votes cast against
the resolution for his removal would,  if  cumulatively  voted at an election of
the full board, be sufficient to elect one or more directors.

             4.04        Consent

                         A person who is elected or  appointed a director is not
a director unless:

                         A. he was present at the meeting when he was elected or
              appointed and did not refuse to act as a director, or

                         B. if he was not  present  at the  meeting  when he was
              elected or appointed;

                         C. he consented in writing to act as a director  before
              his election or appointment or within ten (10) days after it, or

                         D. he has acted as a director  pursuant to the election
              or appointment.

             4.05        Vacation of Office

                         A director  of the  Corporation  ceases to hold  office
when:

                         A.          he dies or resigns;

                         B. he is removed in accordance  with section 109 of the
              Act; or

                         C. he becomes  disqualified  under subsection 105(1) of
              the Act.

             4.06        Committee of Directors

                         The  directors  may appoint  from among their  number a
managing director, who must be a resident Canadian, or a committee of
directors,  however  designated,  of which a  majority  of the  members  must be
resident  Canadians,  and subject to section 115 of the Act may  delegate to the
managing  director  or such  committee  any of the  powers of the  directors.  A
committee may be comprised of one director.

             4.07        Transaction of Business of Committee

                         Subject to the  provisions  of this by-law with respect
to  participation  by  telephone,  the powers of a committee of directors may be
exercised by a meeting at which a quorum is present or by  resolution in writing
signed by all of the members of such  committee  who would have been entitled to
vote  on  that  resolution  at a  meeting  of the  committee.  Meetings  of such
committee may be held at any place in or outside Canada and may be called by any
one  member of the  committee  giving  notice  in  accordance  with the  by-laws
governing the calling of directors' meetings.

             4.08        Procedure

                         Unless  otherwise  determined  herein or by the  board,
each  committee  shall  have the  power  to fix its  quorum  at not less  than a
majority of its members, to elect its chairman and to regulate its procedure.

             4.09        Remuneration and Expenses

                         Subject to any  unanimous  shareholder  agreement,  the
directors  shall be paid such  remuneration  for their services as the board may
from  time to time  determine.  The  directors  shall  also  be  entitled  to be
reimbursed  for  traveling  and  other  expenses  properly  incurred  by them in
attending  meetings  of the  board  or any  committee  thereof.  Nothing  herein
contained  shall preclude any director from serving the Corporation in any other
capacity and receiving remuneration therefor.

             4.10        Vacancies

                         Subject  to the Act,  a quorum  of the board may fill a
vacancy among the directors,  except a vacancy resulting from an increase in the
number or minimum  number of  directors or from a failure to elect the number or
minimum number of directors  required by the articles.  If there is not a quorum
of  directors,  or if there has been a failure  to elect the  number or  minimum
number of directors required by the articles, the directors then in office shall
forthwith  call a special  meeting of  shareholders  to fill the vacancy and, if
they fail to call a meeting or if there are no  directors  then in  office,  the
meeting may be called by any shareholder.

             4.11        Action by the Board

                         Subject to any  unanimous  shareholder  agreement,  the
board shall manage the business and affairs of the Corporation.  Notwithstanding
a vacancy among the directors, a quorum of directors may exercise all the powers
of the directors.  If the Corporation  has only one director,  that director may
constitute a meeting.

             5.02        Notice of Meeting

                         Unless the directors have made  regulations  otherwise,
meetings  of the  board may be  summoned  on  twenty-four  (24)  hours'  notice,
verbally or in writing,  and whether by means of telephone or telegraph,  or any
other  means of  communication.  A notice of a  meeting  of  directors  need not

any proposal to:

                         A. submit to the  shareholders  any  question or matter
              requiring approval of the shareholders;

                         E. purchase,  redeem or otherwise acquire shares issued

                         Provided,  however,  that a director  may in any manner
waive notice of a meeting and attendance of a director at a meeting of directors
shall  constitute  a waiver of notice of the  meeting  except  where a  director
attends a meeting for the express purpose of objecting to the transaction of any
business on the grounds that the meeting is not lawfully called.

                         For the first  meeting of the board of  directors to be
held  immediately  following  an election of  directors  or for a meeting of the
board at which a director is to be appointed to fill a vacancy in the board,  no
notice of such  meeting  shall be  necessary  to the newly  elected or appointed
director or directors in order to legally constitute the meeting,  provided that
a quorum of the directors is present.

             5.03        Adjourned Meeting

                         Notice  of an  adjourned  meeting  of the  board is not

original meeting.

                         Meetings  of the board  shall be held from time to time

managing director, the president or any two directors may determine. Should more
than one of the  above-named  call a meeting  at or for  substantially  the same
time,  there shall be held only one meeting and such meeting  shall occur at the
time and place determined by, in order of priority,  the board, the chairman, or
the president.

             5.05        Regular Meetings

meetings  shall be sent to each  director  forthwith  after  being  passed,  and
forthwith  to each  director  subsequently  elected or  appointed,  but no other
notice shall be required for any such  regular  meeting  except where the Act or
this by-law  requires  the  purpose  thereof or the  business  to be  transacted
thereat to be specified.

             5.06        Chairman

majority of the directors  holding office or such greater number of directors as
the board may from time to time determine.

             5.08        Majority Canadian Representation at Meetings

                         Directors  shall not transact  business at a meeting of
directors  unless a majority of the  directors  present are resident  Canadians.
Notwithstanding  the foregoing,  directors may transact business at a meeting of
directors  when less than a  majority  of the  directors  present  are  resident
Canadians if:

                         A. a  resident  Canadian  director  who is unable to be
              present   approves   in   writing   or  by   telephone   or  other
              communications  facilities the business transacted at the meeting;
              and

                         B. the number of resident Canadian directors present at
              the  meeting,  together  with any resident  Canadian  director who
              gives his approval under clause (a), constitutes a majority of the
              directors present at the meeting.

             5.09        Voting

                         Questions  arising at any meeting of the board shall be
decided by a majority of votes, the chairman of the meeting shall be entitled to
vote and the chairman shall not have a second or casting vote in the event of an
equality of votes.

             5.10        Meeting by Telephone

                         A director,  if all the  directors  of the  Corporation
consent,  may  participate in a meeting of the board or a committee of the board
by means of such  telephone  or other  communication  facilities  as permit  all
persons  participating  in the  meeting  to  hear  each  other,  and a  director
participating  in such  meeting  by such  means is deemed to be  present  at the
meeting.  Any such consent shall be effective  whether given before or after the
meeting to which it relates and may be given with respect to all meetings of the
board and of committees of directors held while a director holds office.

             5.11        Resolution in Lieu of Meeting

                         Notwithstanding any of the foregoing provisions of this
by-law, a resolution in writing signed by all the directors  entitled to vote on
that  resolution at a meeting of the directors or a committee of directors is as
valid as if it had been passed at a meeting of the  directors  or  committee  of
directors. A copy of every such resolution shall be kept with the minutes of the
proceedings of the directors or committee of directors.  Any such  resolution in
writing is  effective  for all  purposes at such time as the  resolution  states
regardless of when the resolution is signed.

             5.12        Amendments to the Act

                         It is hereby  affirmed  that the  intention of sections
4.06, 5.08 and 7.03 as they relate to Canadian  representation is to comply with
the  minimum  requirements  of the  Act  and  in the  event  that  such  minimum
requirements  shall be  amended,  deleted or  replaced  such that no, or lesser,
requirements  with respect to Canadian  representation  are then in force,  such
sections shall be correspondingly amended, deleted or replaced.

                  PROTECTION OF DIRECTORS, OFFICERS AND OTHERS

             6.01        Conflict of Interest

                         A director or officer shall not be  disqualified by his
office,  or be required to vacate his office,  by reason only that he is a party
to, or is a director or officer or has a material  interest in any person who is
a party  to,  a  material  contract  or  proposed  material  contract  with  the
Corporation or a subsidiary thereof.  Such a director or officer shall, however,
disclose  the nature and extent of his  interest in the contract at the time and
in the  manner  provided  by the Act.  Subject to the  provisions  of the Act, a
director  shall  not  by  reason  only  of  his  office  be  accountable  to the
Corporation or to its  shareholders  for any profit or gain realized from such a
contract or transaction,  and such contract or transaction  shall not be void or
voidable by reason only of the director's  interest  therein,  provided that the
required  declaration  and disclosure of interest is properly made, the contract
or transaction is approved by the directors or shareholders,  if necessary,  and
it was fair and  reasonable to the  Corporation at the time it was approved and,
if required by the Act, the director  refrains  from voting as a director on the
contract or transaction.

             6.02        Limitation of Liability

                         Every  director  and  officer  of  the  Corporation  in
exercising his powers and  discharging his duties shall act honestly and in good
faith with a view to the best  interests of the  Corporation  and shall exercise
the care, diligence and skill that a reasonably prudent person would exercise in
comparable  circumstances.  Subject to the foregoing, no director or officer for
the time  being of the  Corporation  shall be liable for the acts,  neglects  or
defaults of any other  director or officer or employee or for joining in any act
for conformity,  or for any loss, damage or expense happening to the Corporation
through the insufficiency or deficiency of title to any property acquired by the
Corporation or for or on behalf of the Corporation or for the  insufficiency  or
deficiency of any security in or upon which any of the moneys of or belonging to
the  Corporation  shall be placed out or invested  or for any loss,  conversion,
misapplication or  misappropriation of or any damage resulting from any dealings
with any moneys,  securities or other assets belonging to the Corporation or for
any loss or damage arising from the  bankruptcy,  insolvency or tortious acts of
any person with whom any of the moneys, securities or effects of the Corporation
shall be  deposited,  or for any loss  occasioned  by any error of  judgment  or
oversight on his part, or for any other loss damage or misfortune whatever which
may happen in the execution of the duties of his  respective  office or trust or
in relation thereto;  provided that nothing herein shall relieve any director or
officer  from the  duty to act in  accordance  with the Act and the  Regulations
thereunder or from liability for any breach thereof.  The directors for the time
being of the  Corporation  shall  not be under  any  duty or  responsibility  in
respect of any contract, act or transaction whether or not made, done or entered
into in the name or on behalf of the Corporation, except such as shall have been
submitted to and authorized or approved by the board of directors.

                         No act or  proceeding of any director or officer or the
board  shall be deemed  invalid  or  ineffective  by  reason  of the  subsequent
ascertainment  of any  irregularity  in regard to such act or  proceeding or the
election, appointment or qualification of such director or officer or board.

             6.03        Indemnity

                         Subject  to  section  124 of the Act,  the  Corporation
shall indemnify a director or officer of the  Corporation,  a former director or
officer of the  Corporation  or a person who acts or acted at the  Corporation's
request as a director or officer of a body corporate of which the Corporation is
or was a  shareholder  or  creditor,  and his heirs  and legal  representatives,
against all costs,  charges and expenses,  including an amount paid to settle an
action or  satisfy a  judgment,  reasonably  incurred  by him in  respect of any
civil,  criminal or  administrative  action or  proceeding to which he is made a
party by reason of being or having been a director or officer of the Corporation
or body corporate, if:

                         A. he acted  honestly  and in good faith with a view to
              the best interests of the Corporation; and

                         B. in the case of a criminal or  administrative  action
              or  proceeding  that is  enforced  by a monetary  penalty,  he had
              reasonable grounds for believing that his conduct was lawful.

                         The  Corporation  shall also  indemnify such persons in
such  other  circumstances  as the  Act  permits  or  requires.  Nothing  herein
contained  shall limit the right of any person  entitled to  indemnity  to claim
indemnity apart from the provisions of this section 6.03.

             6.04        Insurance

                         The Corporation may purchase and maintain insurance for
the benefit of any person  referred  to in section  6.03  against any  liability
incurred by him:

                         A. in his  capacity  as a  director  or  officer of the
              Corporation,  except where the liability relates to his failure to
              act honestly  and in good faith with a view to the best  interests
              of the Corporation; or

                         B. in his  capacity  as a  director  or  officer of the
             another body  corporate  where he acts or acted in that capacity at
             the  Corporation's  request,  except where the liability relates to
             his  failure to act  honestly  and in good faith with a view to the
             best interests of the body corporate.

of directors shall be determined from time to time by resolution of the board of

                         Subject to the Act, the annual meeting of  shareholders
shall be held at such time and on such day in each year and  subject  to section
8.03,  at such  place or places as the board,  the  chairman  of the board,  the
managing  director or the  president  may from time to time  determine,  for the
purpose of considering the financial  statements and reports required by the Act
to be placed before the annual meeting, electing directors,  appointing auditors
if required by the Act or the articles,  and for the  transaction  of such other
business as may properly be brought before the meeting.

             8.02        Special Meetings

                         The  board  shall  have  the  power  to call a  special

                         Meetings  of  shareholders  shall be held at any  place

shareholders  entitled  to vote at the  meeting so agree or if the  articles  so
provide, outside Canada.

             8.04        Record Date for Notice

                         The board may fix in advance a date, preceding the date
of any  meeting  of  shareholders  by not more than fifty (50) days and not less
than  twenty-one  (21)  days,  as  a  record  date  for  the   determination  of
shareholders  entitled to notice of the meeting. If no record date is fixed, the
record date for the determination of the shareholders entitled to receive notice
of the meeting shall be the close of business on the date immediately  preceding
the day on which the notice is given or, if no notice is given, the day on which
the meeting is held.

             8.05        Notice of Meeting

                         Notice  of the  time  and  place  of  each  meeting  of
shareholders  shall be sent not less than twenty-one (21) days and not more than
fifty (50) days before the meeting to each  shareholder  entitled to vote at the
meeting,  each director and the auditor of the  Corporation.  Such notice may be
sent by mail addressed to, or may be delivered  personally to, the  shareholder,
at his latest address as shown in the records of the Corporation or its transfer
agent,  to the  director,  at his latest  address as shown in the records of the
Corporation  or in the last notice  filed  pursuant to section 106 or 113 of the
Act, or to the  auditor,  at his most recent  address as shown in the records of
the  Corporation.  A  notice  of  meeting  of  shareholders  sent  by  mail to a
shareholder,  director or auditor in  accordance  with the above is deemed to be
sent on the day on which it was  deposited in the mail. A notice of a meeting is
not required to be sent to shareholders who are not registered on the records of
the Corporation or its transfer agent on the record date as determined according
to section 8.04 hereof.  Notice of a meeting of  shareholders  at which  special
business  is to be  transacted  shall  state  the  nature  of such  business  in
sufficient  detail to permit the shareholder to form a reasoned judgment thereon
and shall  state  the text of any  special  resolution  to be  submitted  to the
meeting.

             8.06        Right to Vote

                         Subject to the  provisions  of the Act as to authorized
representatives  of any other body corporate,  at any meeting of shareholders in
respect of which the  Corporation  has prepared the list  referred to in section
8.07  hereof,  every  person who is named in such list shall be entitled to vote
the shares shown thereon opposite his name except to the extent that such person
has  transferred any of his shares after the record date set pursuant to section
8.04  hereof,  or, if no record date is fixed,  after the date on which the list
referred to in section  8.07 is prepared,  and the  transferee,  upon  producing
properly endorsed certificates  evidencing such shares or otherwise establishing
that he owns such  shares,  demands  not later  than ten (10)  days  before  the
meeting that his name be included to vote the transferred shares at the meeting.
In the  absence  of a list  prepared  as  aforesaid  in  respect of a meeting of
shareholders,  every  person shall be entitled to vote at the meeting who at the
close of business on the record date,  or if no record date is set, at the close
of business  on the date  preceding  the date notice is sent,  is entered in the
securities  register as the holder of one or more shares  carrying  the right to
vote at such meeting.

             8.07        List of Shareholders Entitled to Notice

                         For every meeting of shareholders the Corporation shall
prepare a list of  shareholders  entitled  to  receive  notice  of the  meeting,
arranged in  alphabetical  order,  and showing the number of shares held by each
shareholder.  If a record date for the meeting is fixed pursuant to section 8.04
hereof by the board,  the  shareholders  listed shall be those registered at the
close of business on the record  date.  If no record date is fixed by the board,
the  shareholders  listed  shall be those listed at the close of business on the
day  immediately  preceding  the day on which  notice of a meeting is given,  or
where no such notice is given,  the day on which the  meeting is held.  The list
shall be available for  examination  by any  shareholder  during usual  business
hours at the  registered  office of the  Corporation  or at the place  where its
central securities  register is maintained and at the place where the meeting is
held.

             8.08        Meetings Without Notice

                         A meeting of shareholders may be held without notice at
any time and place permitted by the Act:

                         A. if all the shareholders entitled to vote thereat are
              present in person or  represented by proxy or if those not present
              or  represented  by proxy waive notice of or otherwise  consent to
              such meeting being held; and

                         B. if the  auditors  and the  directors  are present or
              waive notice of or otherwise consent to such meeting being held.

                         At such meetings any business may be  transacted  which
the  Corporation at a meeting of  shareholders  may transact.  If the meeting is
held at a place  outside  Canada,  shareholders  not present or  represented  by
proxy,  but who have waived  notice of or otherwise  consented to such  meeting,
shall also be deemed to have consented to a meeting being held at such place.

             8.09        Waiver of Notice

                         A shareholder and any other person entitled to attend a
meeting  of  shareholders  may  in any  manner  waive  notice  of a  meeting  of
shareholders  and  attendance  of any such  person at a meeting of  shareholders
shall  constitute  a waiver of notice of the  meeting  except  where such person
attends a meeting for the express purpose of objecting to the transaction of any
business on the grounds that the meeting is not lawfully called.

             8.10        Chairman, Secretary and Scrutineers

                         The  chairman  of the  board or,  in his  absence,  the
president,  if such an officer has been elected or appointed and is present,  or
otherwise a  vice-president  who is a shareholder  of the  Corporation  shall be
chairman of any meeting of  shareholders.  If no such officer is present  within
fifteen (15)  minutes  from the time fixed for holding the meeting,  the persons
present and entitled to vote shall choose one of their number to be chairman. If
the  secretary of the  Corporation  is absent,  the chairman  shall appoint some
person,  who need not be a shareholder,  to act as secretary of the meeting.  If
desired, one or more scrutineers, who need not be shareholders, may be appointed
by a resolution or by the chairman with the consent of the meeting.

             8.11        Persons Entitled to be Present

                         The only persons entitled to be present at a meeting of
shareholders shall be those entitled to vote thereat, the directors and auditors
of the Corporation  and others who,  although not entitled to vote, are entitled
or  required  under any  provision  of the Act or the  articles or by-laws to be
present at the meeting.  Any other person may be admitted only on the invitation
of the chairman of the meeting or with the consent of the meeting.

             8.12        Quorum

                         A quorum  at any  meeting  of  shareholders  (unless  a
greater  number of persons  are  required  to be present or a greater  number of
shares are  required to be  represented  by the Act or by the articles or by any
other by-law) shall be persons present not being less than two (2) in number and
holding or representing  not less than five (5%) per cent of the shares entitled
to be voted at the meeting. If a quorum is present at the opening of any meeting
of shareholders,  the  shareholders  present or represented may proceed with the
business of the meeting  notwithstanding that a quorum is not present throughout
the  meeting.  If a quorum is not  present  at the  opening  of the  meeting  of
shareholders, the shareholders present or represented may adjourn the meeting to
a fixed time and place but may not transact any other business.

             8.14        Proxyholders and Representatives

                         Votes  at  meetings  of the  shareholders  may be given
either  personally or by proxy;  or, in the case of a shareholder  who is a body
corporate or  association,  by an  individual  authorized by a resolution of the
board of governing  body of the body corporate or association to represent it at
a meeting of shareholders of the Corporation, upon producing a certified copy of
such  resolution  or  otherwise  establishing  his  authority  to  vote  to  the
satisfaction of the secretary or the chairman.

                         A proxy  shall be executed  by the  shareholder  or his
attorney  authorized  in writing  and is valid only at the meeting in respect of
which it is given or any  adjournment  of that  meeting.  A person  appointed by
proxy need not be a shareholder.

             8.15        Time for Deposit of Proxies

                         The board may specify in a notice  calling a meeting of
shareholders  a time,  preceding  the  time of such  meeting  by not  more  than
forty-eight  (48) hours  exclusive of Saturdays and holidays,  before which time
proxies to be used at such  meeting  must be  deposited.  A proxy shall be acted
upon only if, prior to the time so specified,  it shall have been deposited with
the Corporation or an agent thereof specified in such notice or, if no such time
having been  specified in such notice,  it has been received by the secretary of
the  Corporation  or by the chairman of the meeting or any  adjournment  thereof
prior to the time of voting.

             8.16        Joint Shareholders

                         If two or more persons hold shares jointly,  any one of
them present in person or duly  represented at a meeting of shareholder  may, in
the absence of the other or others, vote the shares; but if two or more of those
persons are present in person or  represented  and vote,  they shall vote as one
the shares jointly held by them.

             8.17        Votes to Govern

                         Except as otherwise  required by the Act, all questions
proposed for the  consideration  of  shareholders  at a meeting of  shareholders
shall be  determined  by a  majority  of the  votes  cast and in the event of an
equality of votes at any meeting of shareholders, either upon a show of hands or
upon a ballot, the chairman shall not have a second or casting vote.

             8.18        Show of Hands

                         Subject  to the  Act,  any  question  at a  meeting  of
shareholders  shall be  decided by a show of hands,  unless a ballot  thereon is
required or demanded as hereinafter provided.  Upon a show of hands every person
who is present and entitled to vote shall have one vote. Whenever a vote by show
of hands  shall have been taken upon a question,  unless a ballot  thereon is so
required or demanded, a declaration by the chairman of the meeting that the vote
upon the question  has been  carried or carried by a particular  majority or not
carried and an entry to that effect in the minutes of the meeting shall be prima
facie  evidence of the fact without proof of the number of the votes recorded in
favor of or against any  resolution  or other  proceeding in respect of the said
question,  and the  result  of the  vote  so  taken  shall  be the  decision  of
shareholders upon the said question.

             8.19        Ballots

                         On any question proposed for consideration at a meeting
of shareholders, a shareholder, proxyholder or other person entitled to vote may
demand and the chairman may require that a ballot be taken either before or upon
the  declaration  of the  result  of any vote by show of  hands.  If a ballot is
demanded on the election of a chairman or on the question of an  adjournment  it
shall be taken forthwith  without an adjournment.  A ballot demanded or required
on any  other  question  shall be taken in such  manner  as the  chairman  shall
direct.  A demand or requirement for a ballot may be withdrawn at any time prior
to the taking of the ballot.  If a ballot is taken each person  present shall be
entitled,  in respect of the shares  that he is  entitled to vote at the meeting
upon the question, to the number of votes as provided for by the articles or, in
the absence of such provision in the articles,  to one vote for each share he is
entitled to vote. The result of the ballot so taken shall be the decision of the
shareholders upon the question.

             8.20        Adjournment

                         The chairman at a meeting of shareholders may, with the
consent of the meeting and subject to such conditions as the meeting may decide,
adjourn the meeting  from time to time and from place to place.  If a meeting of
shareholders  is  adjourned  for less than  thirty  (30)  days,  it shall not be
necessary to give notice of the adjourned meeting, other than by announcement at
the time of the adjournment. Subject to the Act, if a meeting of shareholders is
adjourned  by one or more  adjournments  for an aggregate of thirty (30) days or
more,  notice  of the  adjourned  meeting  shall be given in the same  manner as
notice for an original  meeting  but,  unless the meeting is adjourned by one or
more  adjournments  for an  aggregate  of more than ninety (90) day,  subsection
149(1) of the Act does not apply.

             8.21        Resolution in Lieu of a Meeting

                         Except where not  permitted in the Act, a resolution in
writing signed by all the shareholders  entitled to vote on that resolution at a
meeting of shareholders is as valid as if it had been passed at a meeting of the
shareholders;  and a resolution in writing dealing with all matters  required to
be dealt with at a meeting of  shareholders  and signed by all the  shareholders
entitled to vote at such  meeting,  satisfies  all the  requirements  of the Act
relating to meetings of shareholders. A copy of every such resolution in writing
shall be kept with minutes of the meetings of shareholders.  Any such resolution
in writing is effective for all purposes at such time as the  resolution  states
regardless of when the resolution is signed.

             8.22        Only One Shareholder

                         Where the  Corporation has only one shareholder or only
one holder of any class or series of shares,  the shareholder  present in person
or duly represented constitutes a meeting.

                         Subject  to the Act,  the  Corporation  may  treat  the
registered  holder of any share as the person  exclusively  entitled to vote, to
receive  notices,  to receive any  dividend  or other  payment in respect of the
share,  and  otherwise  to exercise all the rights and powers of an owner of the
share.

             9.02        Certificates

                         The  shareholder  is  entitled at his option to a share
certificate   that  complies  with  the  Act  or  a   non-transferable   written
acknowledgment  of his right to obtain a share  certificate from the Corporation
in respect of the securities of the Corporation held by him. Share  certificates
and   acknowledgments   of  a  shareholder's   right  to  a  share  certificate,
respectively,  shall be in such  form as  described  by the Act and as the Board
shall from time to time approve. A share certificate shall be signed manually by
at least one  director  or  officer of the  Corporation  or by or on behalf of a
registrar,  transfer agent or branch transfer agent of the Corporation,  or by a
trustee  who  certifies  it in  accordance  with  a  trust  indenture,  and  any
additional  signatures  required  on the share  certificate  may be  printed  or
otherwise mechanically reproduced on it.

             9.03        Replacement of Share Certificates

                         The board or any  officer  or agent  designated  by the
board  may  in  its  or  his  discretion  direct  the  issuance  of a new  share

fee and on such terms as to indemnity, reimbursement of expenses and evidence of
loss  and of  title  as the  board  may  from  time to time  prescribe,  whether

             9.04        Joint Holders

                         The  Corporation is not required to issue more than one
share  certificate  in respect of shares held  jointly by several  persons,  and
delivery of a certificate to one of several joint holders is sufficient delivery
to all. Any one of such holders may give effectual  receipts for the certificate
issued in respect thereof or for any dividend, bonus, return of capital or other
money payable or warrant issuable in respect of such certificate.

                                  DIVISION TEN
                             TRANSFER OF SECURITIES

             10.01       Registration of Transfer

                         If  a  share  in  registered   form  is  presented  for
registration of transfer, the Corporation shall register the transfer if:

                         A. the share is endorsed by an appropriate  person,  as
              defined in section 65 of the Act;

                         B.  reasonable  assurance is given that the endorsement
              is genuine and effective;

                         C. the  Corporation has no duty to inquire into adverse
              claims or has discharged any such duty;

                         D. any  applicable  law relating to the  collection  of
              taxes has been complied with;

                         E.  the  transfer  is  rightful  or is to a  bona  fide
              purchaser; and

or remove one or more  agents to  maintain  a central  securities'  register  or
registers and a branch  securities'  register or registers.  Agents so appointed
may be designated as transfer agent or registrar  according to their  functions,
and a person may be appointed and  designated  with  functions as both registrar
and transfer or branch transfer agent.  Registration of the issuance or transfer
of a security in the  central  securities'  register or in a branch  securities'
register is complete and valid registration for all purposes.

             10.03       Securities' Registers

                         A central securities' register of the Corporation shall
be kept at its registered  office or at any other place in Canada  designated by
the  directors  to  record  the  shares  and  other  securities  issued  by  the
Corporation in registered form,  showing with respect to each class or series of
shares and other securities:

                         A. the names,  alphabetically  arranged, and the latest
              known address of each person who is or has been a holder;

                         B. the  number of shares  or other  securities  held by
              each holder; and

                         C.  the  date  and  particulars  of  the  issuance  and
              transfer of each share or other security.

                         A branch securities'  register or registers may be kept
either in or outside Alberta at such place or places as the board may determine.
A branch  securities'  register  shall only contain  particulars  of  securities
issued or transferred at that branch. Particulars of each issue or transfer of a
security  registered in a branch securities'  register shall also be kept in the
corresponding central securities' register.

             10.04       Deceased Shareholders

                         In the event of the death of a holder, or of one of the
joint holders,  of any share, the Corporation  shall not be required to make any
entry in the securities'  register in respect thereof or to make any dividend or
other payments in respect  thereof except upon  production of all such documents
as may be required by law and upon compliance  with the reasonable  requirements
of the Corporation and its transfer agents.

                              DIVIDENDS AND RIGHTS

             11.01       Dividends

                         Subject  to the Act,  the  board  may from time to time
declare  dividends  payable to the  shareholders  according to their  respective
rights  and  interest  in the  Corporation.  Dividends  may be paid in  money or
property or by issuing fully-paid shares of the Corporation.

             11.02       Dividend Cheques

                         A dividend  payable in money shall be paid by cheque to
the order of each registered  holder of shares of the class or series in respect
of which it has been  declared and shall be mailed by prepaid  ordinary  mail to
such registered holder at his address recorded in the Corporation's  securities'
register or registers unless such holder otherwise directs. In the case of joint
holders the cheque shall,  unless such joint holders  otherwise  direct, be made
payable  to the  order of all such  joint  holders  and  mailed to them at their
recorded  address.  The mailing of such cheque as aforesaid,  unless the same is
not paid on due presentation,  shall satisfy and discharge the liability for the
dividend to the extent of the sum represented thereby plus the amount of any tax
which the Corporation is required to and does withhold.

             11.03       Non-Receipt of Cheques

                         In the event of non-receipt  of any dividend  cheque by
the person to whom it is sent as aforesaid,  the Corporation shall issue to such
person a  replacement  cheque for a like  amount on such terms as to  indemnity,
reimbursement  of expenses and evidence of non-receipt and of title as the board
may from time to time prescribe, whether generally or in any particular case.

             11.04       Unclaimed Dividends

                         Any dividend  unclaimed after a period of six (6) years
from the  date on which  the same  has  been  declared  to be  payable  shall be
forfeited and shall revert to the Corporation.

             11.05       Record Date for Dividends and Rights

                         The board may fix in advance a date,  preceding  by not
more than fifty (50) days the date for the payment of any dividend,  as a record
date for the  determination  of the persons  entitled to receive payment of such
dividend, provided that, unless waived as provided for in the Act, notice of any
such record date is given, not less than seven (7) days before such record date,
by  newspaper  advertisement  in the manner  provided  in the Act and by written
notice to each stock  exchange  in Canada,  if any,  on which the  Corporation's
shares  are  listed  for  trading.  Where no record  date is fixed in advance as
aforesaid,  the record date for the  determination  of the  persons  entitled to
receive  payment of any dividend shall be at the close of business on the day on
which the resolution relating to such dividend is passed by the board.

entitled  to  obtain  information  respecting  any  details  or  conduct  of the
Corporation's  business  which  in the  opinion  of the  directors  it  would be
inexpedient in the interests of the Corporation to communicate to the public.

             12.02       Conditions of Access to Information

                         The directors may from time to time,  subject to rights
conferred by the Act,  determine whether and to what extent and at what time and
place  and  under  what  conditions  or  regulations  the  documents,  books and
registers and accounting records of the Corporation or any of them shall be open
to the inspection of shareholders  and no  shareholders  shall have any right to
inspect any  document or book or register or account  record of the  Corporation
except as conferred by statute or  authorized  by the board of directors or by a
resolution of the shareholders.

             12.03       Registered Office and Separate Records Office

                         The registered  office of the Corporation shall be at a
place within Alberta and at such location  therein as the board may from time to
time determine.  The records office will be at the registered  office or at such
location, if any, within Alberta, as the Board may from time to time determine.

             13.01       Method of Giving Notices

                         A  notice  or  document   required  by  the  Act,   the
Regulations, the articles or the by-laws to be sent to a shareholder or director
of the Corporation may be sent by prepaid mail addressed to, or may be delivered
personally to:

                         A. the  shareholder  at his latest  address as shown in
              the records of the Corporation or its transfer agent; and

                         B. the  director at his latest  address as shown in the
              records  of the  Corporation  or in the last  notice  filed  under
              section 106 or 113.

                         A notice or document  sent by mail in  accordance  with
the foregoing to a shareholder  or director of the  Corporation  is deemed to be
received by him at the time it would be delivered in the ordinary course of mail

director did not receive the notice or document at the time or at all.

             13.02       Notice to Joint Shareholders

                         If two or more persons are  registered as joint holders
of any share,  any  notice may be  addressed  to all of such joint  holders  but
notice  addressed to one of such persons  shall be  sufficient  notice to all of
them.

             13.03       Persons Entitled by Death or Operation of Law

                         Every person who, by operation of law, transfer,  death
of a shareholder  or any other means  whatsoever,  shall become  entitled to any
share,  shall be bound by every notice in respect of such share which shall have
been duly given to the shareholders from whom he derives his title to such share
prior to his name and address being entered on the securities' register (whether
such notice was given  before or after the  happening of the event upon which he
became so entitled) and prior to his furnishing to the  Corporation the proof of
authority or evidence of his entitlement prescribed by the Act.

             13.04       Non-Receipt of Notices

                         If a notice or  document  is sent to a  shareholder  in
accordance  with  section  13.01 and the notice or document is returned on three
(3)  consecutive   occasions  because  the  shareholder  cannot  be  found,  the
Corporation  is not  required to send any  further  notice or  documents  to the
shareholder  until he informs  the  Corporation  in writing of his new  address;
provided always,  that in the event of the return of a notice of a shareholders'
meeting mailed to a shareholder in accordance  with section 13.01 of this by-law
the  notice  shall be  deemed  to be  received  by the  shareholder  on the date
deposited in the mail notwithstanding its return.

             13.05       Omissions and Errors

                         Subject to the Act, the accidental omission to give any
notice to any shareholder,  director,  officer, auditor or member of a committee
of the board or the non-receipt of any notice by any such person or any error in
any notice not affecting the substance  thereof shall not  invalidate any action
taken at any meeting held pursuant to such notice or otherwise founded thereon.

             13.06       Signature on Notices

                         Unless otherwise  specifically  provided, the signature

Regulations,  the articles,  the by-laws or otherwise to be sent, the sending of
the notice or document  may be waived or the time for the notice or document may
be waived or  abridged  at any time with the  consent  in  writing of the person
entitled to receive it.

                         The   directors  in  office  when  a   Certificate   of
Continuance  is issued  under  the Act are  hereby  authorized  to  require  the
shareholders of the Corporation to surrender their share certificate, or such of
their share  certificates  as the  directors may  determine,  for the purpose of
canceling the share  certificates and replacing them with new share certificates
that comply with section 49 of the Act, in particular,  replacing existing share
certificate with share certificates that are not negotiable securities under the
Act. The  directors in office shall act by  resolution  under this section 14.01
and shall in their discretion  decide the manner in which they shall require the
surrender  of  existing  share  certificates  and  the  time  within  which  the
shareholders must comply with the requirement and the form or forms of the share
certificates  to be  issued in place of the  existing  share  certificates.  The
directors  may take such  proceedings  as they  deem  necessary  to  compel  any
shareholder to comply with a requirement  to surrender his share  certificate or
certificates  pursuant to this section.  Notwithstanding  any other provision of
this  by-law,  but subject to the Act,  the  director may refuse to register the
transfer  of  shares  represented  by a share  certificate  that  has  not  been
surrendered pursuant to a requirement under this section.

              to be incurred on behalf of the Corporation;

                         C. to a holding body corporate if the  Corporation is a
              wholly-owned subsidiary of the holding body corporate;

                         D. to a subsidiary  body corporate of the  Corporation;
              or

                         E.  to  employees  of  the  Corporation  or  any of its
              affiliates:

                           for the purchase of shares of the  Corporation or any
                           of its affiliates to be held by a trustee;

                                                   

                         and, subject to the Act:

                         A. to any shareholder, director, officer or employee of
              the Corporation or of an affiliated corporation; or

                         B. to any  person for the  purpose of or in  connection
              with  a  purchase  of a  share  issued  or to  be  issued  by  the
              Corporation or an affiliated corporation.

                         The invalidity or  unenforceability of any provision of
this by-law shall not affect the  validity or  enforceability  of the  remaining

                              (REVERSE OF SECURITY)

                     11 1/2% Senior Note due 2004, Series B

                  1.  Interest.   ABRAXAS   PETROLEUM   CORPORATION,   a  Nevada
corporation, and CANADIAN ABRAXAS PETROLEUM LIMITED, a Canadian corporation (the
"Issuers"),  promise to pay interest on the principal amount of this Note at the
rate per annum  shown  above.  Interest  on the Notes will  accrue from the most
recent date on which  interest  has been paid or, if no interest  has been paid,
from November 14, 1996. The Issuers will pay interest  semi-annually  in arrears
on each Interest Payment Date, commencing May 1, 1997. Interest will be computed
on the basis of a 360-day  year of twelve  30-day  months  and, in the case of a
partial month, the actual number of days elapsed.

                  The Issuers  shall pay  interest on overdue  principal  and on
overdue  installments  of interest from time to time on demand at the rate borne
by the Notes and on overdue  installments  of  interest  (without  regard to any
applicable grace periods) to the extent lawful.

                  2. Method of Payment.  The Issuers  shall pay  interest on the
Notes (except defaulted  interest) to the Persons who are the registered Holders
at the close of business on the Record Date  immediately  preceding the Interest
Payment  Date even if the Notes are  cancelled  on  registration  of transfer or
registration of exchange after such Record Date. Holders must surrender Notes to
a Paying Agent to collect  principal  payments.  The Issuers shall pay principal
and interest in money of the United  States that at the time of payment is legal
tender for payment of public and private debts ("U.S.  Legal Tender").  However,
the Issuers may pay  principal  and interest by their check payable in such U.S.
Legal Tender.  The Issuers may deliver any such  interest  payment to the Paying
Agent or to a Holder at the Holder's registered address.

                  3. Paying Agent and Registrar.  Initially, IBJ Schroder Bank &
Trust  Company  (the  "Trustee")  will act as Paying  Agent and  Registrar.  The
Company may change any Paying Agent, Registrar or co-Registrar without notice to
the Holders.

                  4. Indenture. The Issuers issued the Notes under an Indenture,
dated as of  November  14,  1996  (the  "Indenture"),  among  the  Issuers,  the
Subsidiary  Guarantors  and the Trustee.  This Note is one of a duly  authorized
issue of Exchange Notes of the Issuers  designated as their 11 1/2% Senior Notes
due 2004,  Series B (the "Exchange  Notes").  The Notes are limited in aggregate
principal amount to  $215,000,000.  The Notes include the 11 1/2% Notes due 2004
(the "Initial Notes") and the Exchange Notes, issued in exchange for the Initial
Notes pursuant to the Registration  Rights Agreement.  The Initial Notes and the
Exchange Notes are treated as a single class of securities  under the Indenture.
Capitalized  terms herein are used as defined in the Indenture  unless otherwise
defined herein. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code ss.ss.  77aaa-77bbbb) (the "TIA"), as in effect on the date of the
Indenture.  Notwithstanding  anything  to the  contrary  herein,  the  Notes are
subject to all such terms,  and Holders of Notes are  referred to the  Indenture
and  said  Act  for a  statement  of  them.  The  Notes  are  general  unsecured
obligations of the Issuers.

                  5. Indenture.  Each Holder,  by accepting a Note, agrees to be
bound by all of the terms and  provisions of the  Indenture,  as the same may be
amended from time to time in accordance with its terms.

                  6. Redemption.  The Notes will be redeemable,  at the Issuers'
option, in whole at any time or in part from time to time, on and after November
1, 2000,  upon not less than 30 nor more than 60 days' notice,  at the following
Redemption  Prices (expressed as percentages of the principal amount thereof) if
redeemed during the  twelve-month  period  commencing on November 1 of the years
set below, plus, in each case,  accrued and unpaid interest,  if any, thereon to
the date of redemption:


                  Year                                  Percentage
                  ----                                  ----------
                  2000...................                105.750%
                  2001...................                102.875%
                  2002 and thereafter....                100.000%

                  At any time,  or from time to time,  on or prior to _________,
1999,  the Issuers  may, at their  option,  use all or a portion of the net cash
proceeds of one or more Equity Offerings (as defined in the Indenture) to redeem
up to 35% of the aggregate  principal amount of the Notes originally issued at a
Redemption Price equal to 111.5% of the aggregate  principal amount of the Notes
to be redeemed, plus accrued and unpaid interest, if any, thereon to the date of
redemption; provided, however, that at least $139.75 million aggregate principal
amount of Notes remains outstanding  immediately after giving effect to any such
redemption (it being expressly  agreed that for purposes of determining  whether
this  condition  is  satisfied,  Notes  owned by  either  Issuer or any of their
Affiliates  shall be  deemed  not to be  outstanding).  In order to  effect  the
foregoing redemption with the proceeds of any Equity Offering, the Issuers shall
make such redemption not more than 60 days after the  consummation of any Equity
Offering.

                  7. Notice of Redemption.  Notice of redemption  will be mailed
at least 30 days but not more than 60 days  before the  Redemption  Date to each
Holder of Notes to be redeemed at such  Holder's  registered  address.  Notes in
denominations larger than $1,000 may be redeemed in part.

                  Except  as set  forth  in the  Indenture,  if  monies  for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption  Date,  then,  unless the Issuers
default in the payment of such Redemption Price plus accrued  interest,  if any,
the Notes called for redemption  will cease to bear interest from and after such
Redemption  Date and the only  right of the  Holders  of such  Notes  will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  8. Offers to Purchase. Sections 4.15 and 4.16 of the Indenture
provide that,  after certain Asset Sales (as defined in the  Indenture) and upon
the occurrence of a Change of Control (as defined in the Indenture), and subject
to further  limitations  contained  therein,  the Issuers  will make an offer to
purchase  certain  amounts of the Notes in accordance  with the  procedures  set
forth in the Indenture.

                  9.  Denominations;   Transfer;  Exchange.  The  Notes  are  in
registered  form,  without  coupons,  and  (except  Notes  issued as  payment of
Interest) in denominations of $1,000 and integral  multiples of $1,000. A Holder
shall  register  the  transfer  of or  exchange  Notes  in  accordance  with the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents  and to pay certain  transfer
taxes or  similar  governmental  charges  payable  in  connection  therewith  as
permitted by the  Indenture.  The Registrar need not register the transfer of or
exchange of any Notes or portions thereof selected for redemption.

                  10.  Persons Deemed  Owners.  The registered  Holder of a Note
shall be treated as the owner of it for all purposes.

                  11.  Unclaimed Money. If money for the payment of principal or
interest  remains  unclaimed for one year, the Trustee and the Paying Agent will
pay the money back to the Issuers.  After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

                  12. Discharge Prior to Redemption or Maturity.  If the Issuers
at any time  deposit  with the  Trustee  U.S.  Legal  Tender or U.S.  Government
Obligations  sufficient  to pay the  principal  of and  interest on the Notes to
redemption  and  comply  with the other  provisions  of the  Indenture  relating
thereto, the Issuers will be discharged from certain provisions of the Indenture
and  the  Notes  (including   certain   covenants,   including,   under  certain
circumstances,  their  obligation  to pay the  principal  of and interest on the
Notes but without  affecting  the rights of the Holders to receive  such amounts
from such deposit).

                  13.  Amendment;   Supplement;   Waiver.   Subject  to  certain
exceptions set forth in the Indenture, the Indenture or the Notes may be amended
or  supplemented  with the  written  consent  of the  Holders of not less than a
majority in aggregate  principal amount of the Notes then  outstanding,  and any
past  Default or Event of Default or  noncompliance  with any  provision  may be
waived  with the  written  consent of the Holders of not less than a majority in
aggregate  principal amount of the Notes then outstanding.  Without notice to or
consent of any Holder, the parties thereto may amend or supplement the Indenture
or  the  Notes  to,  among  other  things,   cure  any   ambiguity,   defect  or
inconsistency,  provide for  uncertificated  Notes in addition to or in place of
certificated  Notes,  comply with any requirements of the Commission in order to
effect or maintain the  qualification  of the Indenture  under the TIA or comply
with  Article  Five of the  Indenture  or make any  other  change  that does not
adversely affect the rights of any Holder of a Note.

                  14.  Restrictive  Covenants.  The  Indenture  imposes  certain
limitations  on the ability of the Issuers and the Restricted  Subsidiaries  to,
among other things, incur additional  Indebtedness,  make payments in respect of
their Capital Stock or certain Indebtedness, make certain Investments, create or
incur liens,  enter into transactions with Affiliates,  create dividend or other
payment restrictions affecting Restricted Subsidiaries, issue Preferred Stock of
their  Restricted  Subsidiaries,  and on the  ability of the  Issuers  and their
Restricted  Subsidiaries to merge or consolidate  with any other Person or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of the Issuers'  and their  Restricted  Subsidiaries'  assets or adopt a plan of
liquidation.   Such   limitations   are   subject  to  a  number  of   important
qualifications  and exceptions.  Pursuant to Section 4.06 of the Indenture,  the
Issuers must annually report to the Trustee on compliance with such limitations.

                  15. Successors.  When a successor assumes,  in accordance with
the Indenture,  all the obligations of its  predecessor  under the Notes and the
Indenture, the predecessor, subject to certain exceptions, will be released from
those obligations.

                  16.  Defaults and Remedies.  If an Event of Default occurs and
is  continuing,  the  Trustee or the  Holders of not less than 25% in  aggregate
principal  amount of Notes then  outstanding may declare all the Notes to be due
and  payable  in the  manner,  at the time and with the effect  provided  in the
Indenture. Holders of Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee is not obligated to enforce the Indenture
or the Notes unless it has received indemnity reasonably satisfactory to it. The
Indenture permits, subject to certain limitations therein provided, Holders of a
majority in aggregate  principal  amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of Notes notice of any continuing  Default or Event of Default (except a
Default  in payment  of  principal  or  interest  when due,  for any reason or a
Default in compliance  with Article Five of the Indenture) if it determines that
withholding notice is in their interest.

                  17.  Trustee  Dealings  with  Issuers.  The Trustee  under the
Indenture,  in its  individual  or any other  capacity,  may become the owner or
pledgee of Notes and may otherwise deal with the Issuers,  their Subsidiaries or
their respective Affiliates as if it were not the Trustee.

                  18. No Recourse Against Others. No partner, director, officer,
employee or stockholder,  as such, of either Issuer or any Subsidiary Guarantor,
as such,  shall have any liability for any  obligations  of either Issuer or any
Subsidiary  Guarantor  under the Notes,  the  Indenture,  the  Guarantees or the
Registration  Rights  Agreement  or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting
a Note waives and releases all such  liability.  The waiver and release are part
of the consideration for the issuance of the Notes.

                  19. Guarantees.  This Note will be entitled to the benefits of
certain  Guarantees,  if any, made for the benefit of the Holders.  Reference is
hereby  made  to  the  Indenture  for a  statement  of  the  respective  rights,
limitations  of rights,  duties and  obligations  thereunder  of the  Subsidiary
Guarantors, the Trustee and the Holders.

                  20.  Authentication.  This Note  shall not be valid  until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                  21.  Governing  Law.  This  Note  and the  Indenture  shall be
governed by and construed in accordance  with the laws of the State of New York,
as applied to contracts made and performed within the State of New York, without
regard to principles of conflict of laws.  Each of the parties  hereto agrees to
submit to the  jurisdiction of the courts of the State of New York in any action
or proceeding arising out of or relating to this Note.

                  22. Abbreviations and Defined Terms.  Customary  abbreviations
may be used in the name of a Holder of a Note or an  assignee,  such as: TEN COM
(= tenants in common),  TEN ENT (= tenants by the  entireties),  JT TEN (= joint
tenants  with  right of  survivorship  and not as tenants  in  common),  CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

                  23. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security  Identification  Procedures,  the Issuers have
caused CUSIP numbers to be printed on the Notes as a convenience  to the Holders
of the Notes.  No  representation  is made as to the accuracy of such numbers as
printed on the Notes and reliance may be placed only on the other identification
numbers printed hereon.

request and without charge a copy of the  Indenture,  which has the text of this

                     NOTE: SIGNATURES MUST BE PROVIDED BELOW
               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Pursuant to the terms and  subject to the  conditions  of the  Exchange
Offer  (as  described  below)  of  Abraxas  Petroleum   Corporation,   a  Nevada
corporation  ("Abraxas")  and  Canadian  Abraxas  Petroleum  Limited,  a  Canada
corporation  ("Canadian Abraxas" and, together with Abraxas, the "Issuers"),  to
holders of the Issuers' 11.5% Senior Notes due 2004, Series A issued pursuant to
the Offering  Memorandum  dated November 5, 1996 (the "Series A Notes"),  as set
forth in the Prospectus  dated  ___________,  1996 (the  "Prospectus")  and this
Letter of  Transmittal  (which,  together with the  Prospectus,  constitute  the
Exchange Offer),  the signer of this Letter of Transmittal (the "Holder") hereby
accepts the Exchange  Offer and tenders the Series A Notes listed on this Letter
of Transmittal in exchange for a like principal amount of 11.5% Senior Notes due
2004,  Series B (the "Exchange  Notes").  The Exchange  Notes are  substantially
identical  to the Series A Notes  except that the resale of the  Exchange  Notes
will not be subject to the restrictions of Rule 144A under the Securities Act of
1933,  as amended (the  "Securities  Act"),  and the Exchange  Notes will not be
subject to certain  interest rate increase  provisions  which were applicable to
the  Series A Notes in  certain  circumstances  relating  to the  timing  of the
Exchange  Offer.  The Holder  hereby  acknowledges  receipt  of the  Prospectus.
Capitalized terms used but not defined herein have the respective meanings given
such terms in the Prospectus.

         Accordingly, subject to, and effective upon, acceptance for exchange of
the Series A Notes tendered herewith in accordance with the terms and conditions
of the Exchange  Offer,  the Holder hereby  sells,  assigns and transfers to the
Issuers all right,  title and  interest in and to all of the Series A Notes that
are being tendered for exchange hereby, and hereby  irrevocably  constitutes and
appoints the Exchange  Agent the true and lawful agent and  attorney-in-fact  of
the Holder  with  respect to such  securities,  with full power of  substitution
(such power of attorney being deemed to be an irrevocable  power coupled with an
interest),  to (i) deliver Series A Notes tendered hereby or transfer  ownership
of such  securities on the account books  maintained by DTC together,  in either
such case,  with the  accompanying  evidences of transfer and authority,  to the
Issuers upon the receipt by the Exchange  Agent,  as the Holder's  agent, of the
consideration  therefor  pursuant to the  Exchange  Offer,  and (ii) receive all
benefits  and  otherwise  exercise  all rights of  beneficial  ownership of such
Series A Notes.

         THE HOLDER  HEREBY  REPRESENTS  AND  WARRANTS  THAT THE HOLDER HAS FULL
POWER AND AUTHORITY TO TENDER,  EXCHANGE, SELL, ASSIGN AND TRANSFER THE SERIES A
NOTES  TENDERED  HEREBY AND TO ACQUIRE  THE  EXCHANGE  NOTES  ISSUABLE  UPON THE
EXCHANGE OF SUCH  TENDERED  SECURITIES,  THAT THE ISSUERS  WILL ACQUIRE GOOD AND
UNENCUMBERED TITLE TO SUCH TENDERED SERIES A NOTES, FREE AND CLEAR OF ALL LIENS,
RESTRICTIONS,  CHARGES AND ENCUMBRANCES,  AND THE SERIES A NOTES TENDERED HEREBY
ARE NOT SUBJECT TO ANY ADVERSE CLAIM OR  ENCUMBRANCE  WHEN THE SAME ARE ACCEPTED
BY THE  ISSUERS.  THE  HOLDER  WILL,  UPON  REQUEST,  EXECUTE  AND  DELIVER  ANY
ADDITIONAL DOCUMENTS DEEMED BY THE ISSUERS OR THE EXCHANGE AGENT TO BE NECESSARY
OR DESIRABLE  TO COMPLETE THE  EXCHANGE,  SALE,  ASSIGNMENT  AND TRANSFER OF THE
SERIES A NOTES TENDERED HEREBY.

         All authority herein conferred or agreed to be conferred in this Letter
of  Transmittal  shall survive the death or  incapacity  of the Holder,  and any
obligation  of the Holder  hereunder  shall be binding upon the heirs,  personal
representatives,  successors and assigns of the Holder.  Except as stated in the
Prospectus, this tender is irrevocable.

         A tender of Series A Notes pursuant to the procedures  described in the
Prospectus  and  in  the  instructions   hereto  will  constitute  the  Holder's
acceptance  of the  terms and  conditions  of the  Exchange  Offer and a binding
agreement  between the  tendering  Holder of Series A Notes and the Issuers upon
the terms and  subject  to the  conditions  of the  Exchange  Offer.  The Holder
recognizes that, under certain  circumstances  set forth in the Prospectus,  the
Issuers  may not be required  to accept any of the Series A Notes  tendered  for
exchange  hereby.  The Holder hereby  directs that the Exchange Notes and/or any
Series  A  Notes  representing  any  principal  amount  of such  securities  not
exchanged  be issued in the name of the  Holder.  The  Holder  understands  that
Holders who tender Series A Notes by book-entry transfer ("Book-Entry  Holders")
will receive their Exchange Notes and any principal amount of Series A Notes not
exchanged will be returned to such Book-Entry Holder by crediting in the name of
such Book-Entry Holder the account maintained by DTC. The Holder recognizes that
the Issuers have no  obligation  to transfer any Series A Notes from the name(s)
of the registered holder(s) thereof.

         BY TENDERING  SERIES A NOTES AND EXECUTING THIS LETTER OF  TRANSMITTAL,
THE HOLDER IS DEEMED TO REPRESENT AND AGREE,  AND HEREBY  REPRESENTS AND AGREES,
THAT (I) IT IS ACQUIRING  EXCHANGE  NOTES  ISSUABLE IN EXCHANGE  THEREFOR IN THE
ORDINARY COURSE OF ITS BUSINESS,  (II) UNLESS IT IS A BROKER-DEALER  REFERRED TO
IN THE NEXT  SENTENCE,  IT IS NOT  ENGAGING AND DOES NOT INTEND TO ENGAGE IN THE
DISTRIBUTION  OF THE EXCHANGE  NOTES,  (III) AT THE TIME OF  CONSUMMATION OF THE
EXCHANGE  OFFER THE HOLDER WILL HAVE NO ARRANGEMENT  OR  UNDERSTANDING  WITH ANY
PERSON TO PARTICIPATE IN THE  DISTRIBUTION OF THE EXCHANGE NOTES IN VIOLATION OF
THE PROVISIONS OF THE SECURITIES ACT, (IV) THE HOLDER IS NOT AN AFFILIATE OF ANY
OF THE ISSUERS  WITHIN THE MEANING OF RULE 405 UNDER THE  SECURITIES ACT AND (V)
IF IT  PARTICIPATES  IN THE EXCHANGE OFFER FOR THE PURPOSE OF  DISTRIBUTING  THE
EXCHANGE  NOTES IT MUST COMPLY WITH THE  REGISTRATION  AND  PROSPECTUS  DELIVERY
REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY RESALE OF THE EXCHANGE
NOTES.  EACH  HOLDER WHO IS A  PARTICIPATING  BROKER-DEALER  (AS  DEFINED IN THE
PROSPECTUS)  HOLDING  SERIES A NOTES ACQUIRED FOR ITS OWN ACCOUNT AS A RESULT OF
MARKET-MAKING  OR OTHER TRADING  ACTIVITIES THAT WILL RECEIVE  EXCHANGE NOTES IN
EXCHANGE  FOR  SUCH  SERIES  A NOTES  PURSUANT  TO THE  EXCHANGE  OFFER  FURTHER
REPRESENTS  AND  AGREES  THAT IT WILL  DELIVER A  PROSPECTUS  (WHICH  MAY BE THE
PROSPECTUS)  IN  CONNECTION  WITH ANY RESALE OF SUCH  EXCHANGE  NOTES DURING THE
PERIOD REQUIRED BY THE SECURITIES ACT. BY ACKNOWLEDGING THAT IT WILL DELIVER AND
BY DELIVERING A PROSPECTUS, A PARTICIPATING  BROKER-DEALER WILL NOT BE DEEMED TO
ADMIT THAT IT IS AN "UNDERWRITER" WITHIN THE MEANING OF THE SECURITIES ACT.

FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1.       GUARANTEE OF SIGNATURES.  Signatures on Letters of Transmittal need not

         Instructions"  on the Letter of  Transmittal,  signatures on Letters of
         Transmittal (or facsimiles  thereof) must be guaranteed by a commercial

         States or a firm which is a member of a registered  national securities
         exchange or a member of the National Association of Securities Dealers,
         Inc. (an "Eligible Institution").

2.       DELIVERY  OF  LETTER  OF  TRANSMITTAL  AND  CERTIFICATES.  In  order to
         participate in the Exchange Offer and receive  Exchange Notes, a holder
         must properly complete and duly execute (with signatures  guaranteed if
         required by Instruction  1) the Letter of  Transmittal  (or a facsimile
         thereof) and mail or deliver it, together with the Series A Notes to be
         tendered  for  exchange  (or the  Exchange  Agent must receive a timely
         confirmation  of a book-entry  transfer of such Series A Notes into the
         Exchange Agent's account at DTC as described in the Prospectus) and any
         other required  documents,  to the Exchange  Agent.  The Exchange Agent
         must receive the foregoing documents and instruments on or prior to the
         Expiration  Date.  DELIVERY  OF  DOCUMENTS  TO DTC DOES NOT  CONSTITUTE
         DELIVERY TO THE EXCHANGE AGENT.

         If a holder  desires to tender Series A Notes  pursuant to the Exchange
         Offer and such holder's Series A Notes are not  immediately  available,
         or if the procedure for  book-entry  transfer  cannot be completed on a
         timely basis,  or such holder cannot deliver the Series A Notes and all
         other required  documents to the Exchange Agent prior to the Expiration
         Date,  such  Series A Notes  may be  tendered  if all of the  following
         guaranteed  delivery procedures are complied with: (i) such tenders are
         made by or through an Eligible  Institution;  (ii) a properly completed
         and duly executed Notice of Guaranteed  Delivery,  in substantially the
         form provided by the Issuers,  is received by the Exchange  Agent on or
         prior to the Expiration  Date; and (iii) the Series A Notes,  in proper
         form (or  transfer  for  confirmation  of  book-entry  transfer of such
         Series A Notes into the Exchange Agent's account at DTC as described in
         the Prospectus),  together with a properly  completed and duly executed
         Letter of Transmittal and all other  documents  required by this Letter
         of Transmittal, are received by the Exchange Agent within five New York
         Stock Exchange,  Inc.  trading days after the date of execution of such
         Notice of Guaranteed  Delivery,  all as provided under the caption "The
         Exchange Offer -- How to Tender" in the Prospectus.

         All questions as to the validity,  form, eligibility (including time of
         receipt)  and   acceptability  of  Series  A  Notes  tendered  will  be
         determined  by  the  Issuers  in  their  sole   discretion,   and  such
         determinations will be final and binding. The Issuers reserve the right
         to reject any and all tenders  determined  by their not to be in proper
         form or  otherwise  not valid or the  acceptance  for exchange of which
         may, in the opinion of the  Issuers'  counsel,  be unlawful or to waive
         any  irregularities or conditions.  The Issuers'  interpretation of the
         terms and  conditions of the Exchange  Offer  (including  the Letter of
         Transmittal and  Instructions  thereto) will also be final and binding.
         The  Issuers  and the  Exchange  Agent  are not  under any duty to give
         notification of any  irregularities  or defects and shall not incur any
         liability for failure to give any such  notification.  Tenders will not
         be deemed to have been made until such  irregularities  or defects have
         been cured or waived.  Any tender  (including the Letter of Transmittal
         and Series A Notes) that is not properly completed and executed, and as
         to which  irregularities  or defects  are not cured or waived,  will be
         returned by the Exchange Agent to the tendering  holder  promptly after
         the  Expiration  Date (or, in the case of Series A Notes  delivered  by
         book-entry  transfer  within DTC, the  tendered  Series A Notes will be
         credited to the account maintained within DTC by the participant).

         THE METHOD OF  DELIVERY  OF THIS  LETTER OF  TRANSMITTAL,  THE SERIES A
         NOTES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC,
         IS AT THE  ELECTION  AND RISK OF THE  TENDERING  HOLDER AND,  EXCEPT AS
         OTHERWISE  PROVIDED IN THIS  INSTRUCTION 2, THE DELIVERY WILL BE DEEMED
         MADE ONLY WHEN ACTUALLY  RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS
         BY MAIL,  REGISTERED  MAIL,  WITH RETURN  RECEIPT  REQUESTED,  PROPERLY
         INSURED, IS RECOMMENDED.

         No alternative, conditional or contingent tenders will be accepted. All
         tendering  holders,  by  execution  of this  Letter of  Transmittal  or
         facsimile  hereof,  waive  any  rights  to  receive  any  notice of the
         acceptance of their tender.

3.       INADEQUATE  SPACE.  If the space  provided  herein is  inadequate,  the
         Series A Note numbers and the principal amount of Series A Notes should
         be listed on a separate signed schedule attached hereto.

4.       PARTIAL TENDERS.  If less than all of the principal amount  represented
         by any Series A Note submitted is to be tendered,  the principal amount
         of the Series A Notes which are to be tendered  should be stated in the
         box entitled  "Principal Amount of Series A Notes Tendered." New Series
         A Notes for the remaining  principal amount of the old Series A Note(s)
         will  either be sent to the  registered  holder of the Series A Note(s)
         tendered as soon as  practicable  after the tender has been accepted or
         credited  to  the  holder's  account  in  accordance  with  appropriate
         book-entry  procedures.  The aggregate principal amount of all Series A
         Notes  listed  are  deemed  to  have  been  tendered  unless  otherwise
         indicated.  Partial  tenders  of all Series A Notes may be made only if
         (i) the  principal  amount  tendered  is equal to $1,000 or an integral
         multiple  thereof;  and (ii) the remaining  untendered  portion of such
         Series A Note is in a principal  amount of  $250,000,  or any  integral
         multiple of $1,000 in excess of such amount.

5.       SIGNATURES ON LETTER OF TRANSMITTAL. This Letter of Transmittal must be
         signed by the registered holder of the Series A Note(s) tendered hereby
         and if the Series A Notes are registered the signature must  correspond
         exactly  with the name as  written  on the face of the Series A Note(s)
         with alteration, enlargement or any change whatsoever.

         If the  Series A Notes  tendered  hereby  are owned of record by two or
         more  joint   owners,   all  such  owners  must  sign  this  Letter  of
         Transmittal.

         If this  Letter  of  Transmittal  is  signed  by  trustees,  executors,
         administrators, guardians, attorneys-in-fact,  officers of corporations
         or others  acting  in a  fiduciary  or  representative  capacity,  such
         persons   should  so  indicate  when  signing,   and  proper   evidence
         satisfactory  to the  Issuers  of  their  authority  to so act  must be
         submitted.

6.       DELIVERY OF  EXCHANGE  NOTES.  Delivery of Exchange  Notes will be made
         promptly  after the  Expiration  Date for all  Series A Notes  properly
         tendered and accepted for exchange by the Issuers.  The Exchange  Notes
         of  registered  holders  will be issued  in the name of the  registered
         holder(s)  of the  Series A Notes  and will  either  be  mailed to such
         holder(s)  or  credited to such  holder's  account in  accordance  with
         appropriate book-entry procedures.  In the case of tenders by Notice of
         Guaranteed  Delivery,  Exchange  Notes will not be delivered  until the
         Letter of  Transmittal,  the Series A Notes  relating to such Notice of
         Guaranteed  Delivery (or a timely confirmation of a book-entry transfer
         of such Series A Notes into the  Exchange  Agent's  account of DTC) and
         all other required documents have been received by the Exchange Agent.

7.       SECURITY  TRANSFER  TAXES.  The Issuers will pay all security  transfer
         taxes,  if any,  applicable to the exchange of Series A Notes  tendered
         and accepted pursuant to the Exchange Offer.

8.       BACKUP FEDERAL INCOME TAX WITHHOLDING AND SUBSTITUTE FORM W9. Under the
         federal  income tax laws,  payments  that may be made by the Issuers on
         account of Exchange Notes issued  pursuant to the Exchange Offer may be
         subject  to backup  withholding  at the rate of 31%.  In order to avoid
         such backup withholding, each tendering holder should complete and sign
         the  Substitute  Form W-9  included in this Letter of  Transmittal  and
         either (a) provide the correct taxpayer  identification  number ("TIN")
         and  certify,  under  penalties  of perjury,  that the TIN  provided is
         correct and that (i) the holder has not been  notified by the  Internal
         Revenue  Service  (the  "IRS")  that the  holder is  subject  to backup
         withholding  as a result of failure to report all interest or dividends
         or (ii) the IRS has  notified  the holder  that the holder is no longer
         subject to backup  withholding;  or (b) provide an  adequate  basis for
         exemption.  If the  tendering  holder has not been issued a TIN and has
         applied for one, or intends to apply for one in the near  future,  such
         holder should write  "Applied For" in the space provided for the TIN in
         Part I of the Substitute  Form W-9, sign and date the  Substitute  Form
         W-9 and sign the Certificate of Payee Awaiting Taxpayer  Identification
         Number.  If  "Applied  For" is written in Part I, the  Issuers  (or the
         Paying Agent under the Indenture  governing  the Exchange  Notes) shall
         retain 31% of payments  made to the  tendering  holder during the sixty
         day period following the date of the Substitute Form W-9. If the holder
         furnishes  the Exchange  Agent or the Issuers with its TIN within sixty
         days after the date of the  Substitute  Form W-9,  the  Issuers (or the
         Paying  Agent) shall remit such amounts  retained  during the sixty day
         period to the  holder  and no  further  amounts  shall be  retained  or
         withheld from payments made to the holder thereafter.  If, however, the
         holder has not provided the Exchange  Agent or the Issuers with its TIN
         within such sixty day period,  the Issuers (or the Paying  Agent) shall
         remit  such   previously   retained   amounts  to  the  IRS  as  backup
         withholding.  In general, if a holder is an individual,  the TIN is the
         Social Security number of such individual. If the Exchange Agent or the
         Issuers  are not  provided  with the  correct  TIN,  the  holder may be
         subject  to  a  $50  penalty  imposed  by  the  IRS.   Certain  holders
         (including,   among  others,   all  corporations  and  certain  foreign
         individuals) are not subject to these backup  withholding and reporting
         requirements. In order for a foreign individual to qualify as an exempt
         recipient,  such holder must  submit a statement  (generally,  IRS Form
         W-8), signed under penalties of perjury, attesting to that individual's
         exempt status. Such statements can be obtained from the Exchange Agent.

         Failure to complete the Substitute Form W-9 will not, by itself,  cause
         Notes to be deemed invalidly tendered,  but may require the Issuers (or
         the Paying  Agent) to withhold 31% of the amount of any payment made on
         account of the Exchange Notes.  Backup withholding is not an additional
         federal  income tax.  Rather,  the federal  income tax  liability  of a
         person subject to backup  withholding  will be reduced by the amount of
         tax withheld.  If  withholding  results in an  overpayment  of taxes, a
         refund may be obtained from the IRS.

9.       WAIVER  OF  CONDITIONS.   Subject  to  limitations  set  forth  in  the
         Prospectus,  the  conditions of the Exchange Offer may be waived by the
         Issuers,  in whole or in part, at any time or from time to time, in the
         Issuers' sole discretion in the case of any Series A Notes tendered.

10.      LOST,  DESTROYED OR STOLEN  NOTES.  If any Series A Note has been lost,
         stolen,  mutilated or destroyed,  the holder should promptly notify the
         Trustee, IBJ Schroder Bank & Trust Company, of such fact in writing, or
         call (212)  858-2000.  The holder will then be directed as to the steps
         that must be taken in order to replace the Series A Note. The Letter of
         Transmittal  and  related  documents  cannot  be  processed  until  the
         procedures for replacing lost, stolen,  mutilated or destroyed Series A
         Notes have been followed.

11.      REQUEST FOR  ADDITIONAL  COPIES.  Questions and requests for additional
         copies of the Prospectus and this Letter of Transmittal may be obtained
         from the Exchange  Agent at the address and telephone  number set forth
         in the Prospectus.

12.      PARTICIPATING  BROKER-DEALERS.  Each  Holder  which is a  Participating
         Broker-Dealer must advise the Exchange Agent as to the number of copies
         of the Prospectus  (including  supplements  and amendments  thereto) it
         will require in order to satisfy the prospectus  delivery  requirements
         for resales of Exchange  Notes which are  exchanged  for Series A Notes
         acquired  by it for its own  account  as a result of  market-making  or
         other trading activities.

IMPORTANT TAX INFORMATION

         Under federal income tax laws, a holder whose  tendered  Series A Notes
are accepted  for payment is required to provide the  Exchange  Agent (as payor)
with  such  holder's  correct  TIN on  Substitute  Form W-9  below or  otherwise
establish a basis for exemption  from backup  withholding.  If such holder is an
individual,  the TIN is his social security number. If the Exchange Agent is not
provided  with the correct  TIN, a $50  penalty  may be imposed by the  Internal
Revenue Service.

         Certain holders (including,  among others, all corporations and certain
foreign  persons)  are not subject to these  backup  withholding  and  reporting
requirements.  Exempt holders should  indicate their exempt status on Substitute
Form W-9. A foreign  person may qualify as an exempt  recipient by submitting to
the  Exchange  Agent a properly  completed  Internal  Revenue  Service Form W-8,
signed under penalties of perjury,  attesting to that holder's exempt status.  A
Form W-8 can be obtained from the Exchange Agent.

         If backup  withholding  applies,  the  Exchange  Agent is  required  to
withhold  20% of any  payments  made  to  the  holder  or  other  payee.  Backup
withholding is not an additional  federal income tax. Rather, the federal income
tax liability of persons  subject to backup  withholding  will be reduced by the
amount of tax withheld.  If  withholding  results in an  overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

that the TIN provided on Substitute  Form W-9 is correct (or that such holder is
awaiting  a TIN) and that (A) the  holder  has  been  notified  by the  Internal
Revenue Service that the holder is subject to backup  withholding as a result of
failure to report all interest or dividends or (B) the Internal  Revenue Service
has  notified  the  holder  that the  holder  is no  longer  subject  to  backup
withholding, or (ii) an adequate basis for exemption.

                                 Re:   Registration Statement on Form S-4 filed
                                       by Abraxas Petroleum Corporation and
                                       Canadian Abraxas Petroleum Limited

Dear Sirs:

         We have acted as counsel to  Abraxas  Petroleum  Corporation,  a Nevada
corporation  (the  "Company"),  in connection  with the  registration  under the
Securities Act of 1933, as amended,  pursuant to Registration  Statement on Form
S-4 (the "Registration  Statement"),  of an aggregate of $215,000,000  principal
amount of the Company's and Canadian  Abraxas  Petroleum  Limited's 11.5% Senior
Notes Due 2004 (the "Exchange Notes").

         We have  examined  and are  familiar  with  originals  or  copies,  the
authenticity  of which have been  established to our  satisfaction,  of all such
documents, corporate records, certificates of officers of the Company and public
officials,  and other  instruments  as we have deemed  necessary  to express the
opinion  hereinafter  set  forth.  In  expressing  our  opinion  as to the valid
issuance of shares of the Exchange Notes, we express no opinion as to compliance
with federal and state securities laws.

         Based upon the foregoing, it is our opinion that:

         (1) the  Exchange  Notes  to be  issued  and sold as  described  in the
Registration  Statement have been duly and validly authorized for such issue and
sale and, when so issued, sold and delivered, will be validly issued, fully paid
and nonassessable; and

         (2) the  Exchange  Notes,  when  issued,  sold and  delivered,  will be
binding  obligations of the Company except to the extent that the enforceability
of the  Exchange  Notes may be limited by  bankruptcy,  insolvency,  moratorium,
reorganization,  fraudulent conveyance or other laws or decisions relating to or
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

         The  opinion  expressed  herein is  limited to the laws of the State of
Texas,  the corporation  laws of the State of Nevada and the federal laws of the
United States.

         We hereby consent to the use of our name in the Registration  Statement
as counsel who has expressed an opinion upon certain legal matters in connection
with the  issue  and sale of the  Exchange  Notes  (including  specifically  the
reference  contained  under the caption "Legal  Matters") and to the use of this
opinion as an exhibit to the Registration Statement.

                                                     Yours very truly,

                                            Limited

Dear Sirs:

         We have acted as counsel  to  Canadian  Abraxas  Petroleum  Limited,  a
Canada  corporation (the "Company"),  in connection with the registration  under
the Securities Act of 1933, as amended,  pursuant to  Registration  Statement on
Form  S-4  (the  "Registration  Statement"),  of an  aggregate  of  $215,000,000
principal  amount of the  Company's  11.5% Senior Notes Due 2004 (the  "Exchange
Notes").

         We have  examined  and are  familiar  with  originals  or  copies,  the
authenticity  of which have been  established to our  satisfaction,  of all such
documents, corporate records, certificates of officers of the Company and public
officials,  and other  instruments  as we have deemed  necessary  to express the
opinion  hereinafter  set  forth.  In  expressing  our  opinion  as to the valid
issuance of shares of the Exchange Notes, we express no opinion as to compliance
with federal and state securities laws.

         Based on the foregoing, it is our opinion that:

         1.  the  Exchange  Notes to be  issued  and  sold as  described  in the
Registration  Statement have been duly and validly authorized for such issue and
sale and, when so issued, sold and delivered, will be validly issued, fully paid
and non-assessable; and

         2. the Exchange Notes to be issued, sold and delivered, will be binding
obligations of the Company.

         Our opinion is subject to the following qualifications:

         1. the  enforceability  of the  Exchange  Notes is subject to or may be
limited  by  applicable  bankruptcy,  insolvency,  reorganization,  arrangement,
moratorium  or other  similar  laws  relating  to or  affecting  the  rights  of
creditors generally;

         2. the  enforceability  of the  Exchange  Notes is  subject  to general
principles  of  equity,  including  the fact that  equitable  remedies,  such as
specific  performance and injunctions,  may only be awarded in the discretion of
the court;

         3. an Alberta  court will only render a judgment in lawful  currency of
Canada;

         4.  each  of the  Exchange  Notes  are  stated  to be  governed  by and
construed in accordance  with the laws of the State of New York. With respect to
any opinions  relating to  enforceability of the Exchange Notes, we have assumed
that the laws of the State of New York are not  materially  different from those
of the Province of Alberta and the laws of Canada applicable therein.

         The opinion  expressed herein is limited to the laws of the Province of
Alberta and the federal laws of Canada applicable therein.

         This  opinion is intended  solely for the use of the persons to whom it
is addressed in connection with the transactions  provided for in the Agreements
and may not be relied  upon by any other  person or for any other  purpose,  nor
quoted  from or  referred to in any other  document,  without our prior  written
consent.

         We hereby consent to the use of our name in the Registration  Statement
as counsel who has expressed an opinion upon certain legal matters in connection
with the  issue  and sale of the  Exchange  Notes  (including  specifically  the
references  contained under the captions  "Enforceability  of Civil  Liabilities
Against Foreign  Persons" and "Legal Matters") and to the use of this opinion as
an exhibit to the Registration Statement.


                                                Yours very truly,

         First,  the Advisory  Committee  will  allocate the annual  nonelective
         contributions  in the same ratio that each  Participant's  Compensation
         plus  Excess  Compensation  for  the  Plan  Year  bears  to  the  total
         Compensation plus Excess  Compensation of all Participants for the Plan
         Year.  The  allocation  under this  paragraph,  as a percentage of each
         Participant's  Compensation plus Excess  Compensation,  must not exceed
         the applicable percentage (5.7%, 5.4% or 4.3%) listed under the Maximum
         Disparity Table following Option (i).

         The Advisory  Committee  then will allocate any  remaining  nonelective
         contributions  in the same ratio that each  Participant's  Compensation
         for the Plan Yea r bears to the total  Compensation-of all Participants
         for the Plan Year.

[N/A]    (g) Three-Tiered  Integrated  Allocation  Formula.  First, the Advisory
         Committee  will allocate the annual  nonelective  contributions  in the
         same ratio that each Participant's Compensation for the Plan Year bears
         to the total  Compensation of all  Participants  for the Plan Year. The
         allocation under this paragraph,  as a percentage of each Participant's
         Compensation may not exceed the applicable  percentage  (5.7%,  5.4% or
         4.3%) listed under the Maximum Disparity Table following Option (i).

         As a second tier allocation,  the Advisory  Committee will allocate the
         nonelective  contributions  in the same ratio  that each  Participant's
         Excess  Compensation  for the  Plan  Year  bears to the  total'  Excess
         Compensation  of all  Participants  for the Plan Year.  The  allocation
         under this  paragraph,  as a percentage  of each  Participant's  Excess
         Compensation,  may not exceed the  allocation  percentage  in the first
         paragraph.

         Finally, the Advisory Committee will allocate any remaining nonelective
         contributions  in the same ratio that each  Participant's  Compensation
         for the Plan Year bears to the total  Compensation of all  Participants
         for the Plan Year.

[N/A]    (h) Four-Tiered  Integrated  Allocation  Formula.  First,  the Advisory
         Committee  will allocate the annual  nonelective  contributions  in the
         same ratio that each Participant's Compensation for the Plan Year bears
         to the total  Compensation of all  Participants  for the Plan Year, but
         not exceeding 3% of each Participant's Compensation.

         As a second tier allocation,  the Advisory  Committee will allocate the
         nonelective  contributions  in the same ratio  that each  Participant's
         Excess  Compensation  for the  Plan  Year  bears  to the  total  Excess
         Compensation of all  Participants  for the Plan Year, but not exceeding
         3% of each Participant's Excess Compensation.

         As a third tier  allocation,  the Advisory  Committee will allocate the
         annual   contributions  in  the  same  ratio  that  each  Participant's
         Compensation  plus Excess  Compensation  for the Plan Year bears to the
         total Compensation plus Excess Compensation of all Participants for the
         Plan Year. The allocation under this paragraph, as a percentage of each
         Participant's  Compensation plus Excess  Compensation,  must not exceed
         the applicable percentage (2.7%, 2.4% or 1.3%) listed under the Maximum
         Disparity Table following Option (i).

         The Advisory  Committee  then will allocate any  remaining  nonelective
         contributions  in the same ratio that each  Participant's  Compensation
         for the Plan Year bears to the total  Compensation of all  Participants
         for the Plan Year.

         Plan Year in which Option (d) applies to override the 100% limitation.

[N/A]    (g) By increasing  the top heavy minimum  allocation to 5% for any Plan
         Year in which the 100% limitation  applies,  and to 7 for any Plan Year

[N/A]    (h) By  eliminating  the  top  heavy  minimum  allocation.  [Note:  The
         Employer  may not select this Option (h) if the  defined  benefit  plan
         does not guarantee  the top heavy  minimum  benefit under Code 4416 for
         every Participant in this Plan who is a Non-Key Employee.]

If the  elections  under this  Section 3.18 are not  appropriate  to satisfy the

         5.       Term.

         The Plan will continue until May 16, 2006 or until all shares of Common

         7.       Grant, Exercise Rights and Termination of Options.

                  (a) An Eligible  Participant  shall have an Option,  and shall
thereby  become  and be a  Participant,  only  upon  the due  execution  by such
Eligible  Participant  and the  Company  of an  Option  Agreement  (in the  form
attached hereto as Exhibit A).

                  (b) An Option of a  Participant  may be  exercised  during the
period  such  Option is in  effect  and as set forth  herein  and in the  Option
Agreement,  and  only if  compliance  with  all  applicable  federal  and  state
securities  laws  can  be  effected,  and  may be  exercised  only  by (i)  such
Participant's  completion,  execution and delivery to the Company of a notice of
exercise  as  supplied by the Company and (ii) the payment to the Company of the
aggregate  Exercise Price, as provided under Section 9 hereof, for the shares of
Common Stock to be purchased pursuant to such exercise (as shall be specified by
such  Participant  in such notice) in accordance  with the terms of the Plan and
the Option Agreement.  Except as specifically provided by a duly executed Option
Agreement or unless  waived by the Board of Directors of the Company,  an Option
or any of the rights  thereunder may be exercised by such Participant  only, and
may not be transferred or assigned,  voluntarily,  involuntarily or by operation
of law, except by will or the laws of descent and distribution.

                  (c) Notwithstanding any terms or provisions of the Plan to the
contrary,  the Board of Directors of the Company may delegate to the appropriate
officer or officers of the Company the authority to prepare, execute and deliver
any Option  Agreement  reflecting any Option  granted under the Plan;  provided,
however,  that any such Option  Agreement shall be consistent with the terms and
conditions of the Plan.

                  (d) Subject to the  provisions  of Section 13 hereof,  Options

the  date of  grant;  and  (iv)  25%  shall  become  exercisable  on the  fourth
anniversary of the date of grant;  provided,  however, that the Participant must
be an Eligible Participant at each of the vesting dates and, except as otherwise
set  forth in the  Option  Agreement,  no  Options  may be  exercised  after the
expiration  of  ninety  (90) days  from the date a  Participant  ceases to be an
Eligible Participant.

         8.       Purchase Price of Common Stock.

         The Exercise  Price of an Option shall be equal to one hundred  percent
(100%) of the Fair Market  Value of the shares of Common Stock of the Company on
the date that such Option shall be granted.  The Fair Market Value of the shares
of Common Stock of the Company  shall be the closing price on any given date or,
if no shares of the Common Stock are traded on such date,  the most recent prior
date on which shares of the Common Stock were traded, as quoted on the principal
stock exchange on which the Common Stock has been listed, or if the Common Stock
is not listed on an exchange, the NASDAQ National Market or the NASDAQ Small Cap
Market or, if the Common  Stock is not quoted on the NASDAQ  Stock Market or the
NASDAQ Small Cap Market, the average of the final bid and final asked prices for
a share of the Common  Stock in the  over-the-counter  market as reported by the
National  Quotation Bureau  Incorporated (or any similar  organization or agency
succeeding  to its  functions of reporting  prices) or if the Common Stock is no
longer publicly traded, as determined by the Board of Directors in good faith.

         9.       Payment for Shares of Common Stock.

         Payment by each  Participant  for the shares of Common Stock  purchased
hereunder  shall be made in  accordance  with the terms of any Option  Agreement
executed by such Participant.

         10.      Costs and Expenses.

         All costs and expenses  with respect to the  adoption,  implementation,
interpretation  and  administration  of the Plan shall be borne by the  Company;
provided,  however,  that, except as otherwise specifically provided in the Plan
or the applicable  Option Agreement  between the Company and a Participant,  the
Company  shall not be  obligated to pay any costs or expenses  (including  legal
fees) incurred by any Participant in connection with any Option  Agreement,  the
Plan or any Option or Common Stock held by any Participant.

         11.      No Prior Right of Award.

         Nothing  in the  Plan  shall be  deemed  to give  any  director  of the
Company, or his legal  representatives or assigns, or any other person or entity
claiming under or through him, any contract or other right to participate in the
benefits of the Plan.  Nothing in the Plan shall be construed as  constituting a
commitment, guarantee, agreement or understanding of any kind or nature that the
Company shall continue to engage any individual  (whether or not a Participant).
The Plan shall not  affect,  in any way,  the right of the Company to remove any
director  (whether  or not a  Participant)  at  any  time  and  for  any  reason
whatsoever.  No change of a  Participant's  duties as a director  of the Company
shall result in a  modification  of the terms of any rights of such  Participant
under the Plan or any Option Agreement executed by such Participant.

         12.      Changes in Capital Structure.

         If the  outstanding  shares of Common  Stock  shall be changed  into or
exchanged for a different  number or kind of shares of stock or other securities
or  property  of the  Company or of another  corporation  (whether  by reason of
merger, consolidation, recapitalization, reclassification, split up, combination
of shares or  otherwise),  or if the number of such shares of Common Stock shall
be increased by a stock dividend or stock split,  there shall be substituted for
or added to each share of Common Stock theretofore  reserved for the purposes of
the Plan,  whether  or not such  shares are at the time  subject to  outstanding
Options,  the number and kind of shares of stock or other securities or property
into which each  outstanding  share of Common  Stock  shall be so changed or for
which it shall be so  exchanged,  or to which each such share shall be entitled,
as the  case  may  be.  Outstanding  Options  shall  also  be  considered  to be
appropriately  amended  as to  price  and  other  terms as may be  necessary  or
appropriate to reflect the foregoing  events. If there shall be any other change
in the number or kind of the outstanding shares of Common Stock, or of any stock
or other  securities  or property  into which such Common  Stock shall have been
changed,  or for which it shall have been  exchanged,  and if the Board shall in
its sole discretion  determine that such change equitably requires an adjustment
in the number or kind or price of the shares then  reserved  for the purposes of
the Plan,  or in any Options  theretofore  granted or which may be granted under
the Plan, then such adjustment shall be made by the Board and shall be effective
and binding for all  purposes of the Plan.  In making any such  substitution  or
adjustment pursuant to this Section 12, fractional shares may be ignored.

         The  Board  shall  have  the  power,  in the  event  of any  merger  or
consolidation of the Company with or into any other  corporation,  or the merger
or consolidation of any other corporation with or into the Company, to amend all
outstanding  Options  to  permit  the  exercise  thereof  in whole or in part at
anytime, or from time to time, prior to the effective date of any such merger or
consolidation  (but not more than ten (10) years  after the date of grant of any
incentive  stock option) and to terminate  each such Option as of such effective
date.

         13. Acceleration;  Change in Control.  Unless expressly provided to the
contrary in the Option Agreement:

                   (a)  Upon  the   occurrence   of  a  Change  of  Control  (as
hereinafter  defined),  Options  shall  automatically  become  fully  vested and
exercisable;

                   (b) Anything in this Plan to the contrary notwithstanding, no
termination,  amendment or  modification  of this Plan after the occurrence of a
Change  of  Control   shall  in  any  manner   adversely   affect  any  Eligible
Participant's  rights under this  Section 13 without the written  consent of the
Eligible Participant affected by such termination, amendment or modification.

                   (c) The term "Change of Control" shall mean the occurrence of
any of the following events:

                           (i) any  "person"  or "group" (as such terms are used
in Section  13(d) and 14(d) of the  Exchange  Act is or becomes the  "beneficial
owner" (as defined in Rule 13d-3 under the Exchange Act as in effect on the date
hereof, except that a person shall be deemed to be the "beneficial owner" of all
shares that any such person has the right to acquire  pursuant to any  agreement
or  arrangement  or upon exercise of  conversion  rights,  warrants,  options or
otherwise,  without  regard to the sixty day period  referred  to in such Rule),
directly or indirectly,  of securities  representing 20% or more of the combined
voting power of the Company's then outstanding securities;

                           (ii) any person or group shall make a tender offer or
an exchange offer for 20% or more of the combined  voting power of the Company's
then outstanding securities;

                           (iii)  at  any  time   during   any   period  of  two
consecutive  years,  individuals who at the beginning of such period constituted
the Board and any new  directors,  whose election by the Board or nomination for
election  by the  Company's  stockholders  was  approved  by a vote of at  least
two-thirds  (2/3) of the Company  directors then still in office who either were
the  Company  directors  at the  beginning  of the period or whose  election  or
nomination for election was previously so approved ("Current Directors"),  cease
for any reason to constitute a majority thereof;

                           (iv) the Company shall consolidate, merge or exchange
securities with any other entity and the stockholders of the Company immediately
before  the  effective  time  of  such  transaction  do  not  beneficially  own,
immediately after the effective time of such transaction,  shares entitling such
stockholders to a majority of all votes (without  consideration of the rights of
any class of stock  entitled  to elect  directors  by a separate  class vote) to
which all  stockholders  of the  corporation  issuing cash or  securities in the
consolidation,  merger or share  exchange  would be entitled  for the purpose of
electing  directors  or  where  the  Current  Directors  immediately  after  the
effective  time  of the  consolidation,  merger  or  share  exchange  would  not
constitute a majority of the Board of Directors of the corporation  issuing cash
or securities in the consolidation, merger or share exchange; or

                           (v) any person or group  acquires  50% or more of the
Company's assets.

         Notwithstanding  the foregoing,  however, a Change in Control shall not
be deemed to occur merely by reason of an acquisition of Company  securities by,
or any  consolidation,  merger or exchange of securities  with, any entity that,
immediately  prior to such  acquisition,  consolidation,  merger or  exchange of
securities,  was a  "subsidiary",  as such  term is  defined  below.  For  these
purposes,  the term  "subsidiary"  means (a) any corporation of which 95% of the
capital  stock of such  corporation  is owned,  directly or  indirectly,  by the
Company and (b) any  unincorporated  entity in respect of which the Company has,
directly or indirectly, an equivalent degree of ownership.

         14.      Amendment or Termination of Plan.

         Except  as  otherwise  provided  herein,  the  Plan may be  amended  or
terminated  in whole or in part by the Board of Directors of the Company (in its
sole  discretion),  but no such action shall adversely affect or alter any right
or  obligation  with respect to any Option or Option  Agreement  then in effect,
except to the extent that any such action shall be required or desirable (in the
opinion  of the  Company  or its  counsel)  in order to comply  with any rule or

         (d) provide all necessary services where Abraxas acts or is required to

it shall be entitled to the fees paid to the operator  pursuant to the Operating
Agreements  applicable  to such  Assets),  and  where no third  party  Operating
Agreement  exists in respect of any Petroleum  Rights,  act as operator  thereof
pursuant to the terms of the Operating Procedure;

         (e) review all data, information,  notices and requests tendered by any
third party operator, and take such action as is determined by the Manager to be
in Abraxas' best interest unless the matter involves an expenditure over $50,000
net to Abraxas  (other than operating  costs incurred in the ordinary  course of
business) in which case, the Manager shall advise Abraxas as to its  alternative
courses of action,  make Manager's  recommendation  and then obtain  approval of
such action as Abraxas shall determine and, where  necessary,  to facilitate the
action so determined, arrange for any required expertise on behalf of Abraxas;

         (f) negotiate,  on behalf of and in the name of Abraxas and arrange for
any and all contracts with third parties for the proper management and operation
of the Assets;

         (g) make  available,  in performing  its duties  hereunder,  the office
space, equipment and staff including all accounting,  secretarial, corporate and
administrative  services as may be  reasonably  necessary  to perform its duties
hereunder;

         (h) unless produced  Petroleum  Substances are taken in kind by Abraxas
as  herein  provided,  sell or  arrange  for the  sale of  Petroleum  Substances

collection of receivables relating thereto;

         (i) arrange for such audit,  legal,  insurance  and other  professional
services as are required by Abraxas in  connection  with the Assets from time to
time;

         (j) arrange  for all  required  petroleum  engineering  and  geological
services to  adequately  assess and evaluate the Assets from time to time and as
requested or required by Abraxas or its lenders;

         (k) arrange for the payment of all properly  payable  costs,  expenses,
rentals, royalties and similar payments and all property,  severance and similar
taxes in respect of the Assets incurred by or on behalf of Abraxas;

         (l) where requested by Abraxas,  provide  assistance in connection with
arranging  financing or  production  hedging in respect of the Assets  including
providing, or where appropriate to the circumstances,  technical engineering and
geological  assistance,  and providing  financial  analysis and general business
advice on the terms and conditions of any such financing;

         (m) subcontract to third parties, with the prior written consent of and
on terms satisfactory to Abraxas, the responsibilities of the Manager hereunder;

         (n)  prepare  and  distribute  to  Abraxas  all  statements,   reports,

from time to time by Abraxas;

         (o)  file,  or cause to be  filed,  all  reports  or other  information
required by any governmental authority with jurisdiction over the Assets; and

         (p) do all other and further  things  necessary or desirable to operate
the Assets  for the  benefit  of  Abraxas  in  accordance  with good oil and gas
industry practice.

2.2      Consultation

         The Manager  shall advise and consult with Abraxas from time to time as
requested  by  Abraxas  and in any event  with  regard to any  material  matters
relating to the orderly  development  and  operation of the Assets.  For greater
certainty,  but without  limiting the generality of the  foregoing,  the Manager
shall consult with Abraxas before commencing, initiating or participating in any
operation in respect of the Assets which has the possibility of causing material
damage to the  Assets  (such  damage to  include  such  things as  damaging  the
reserves so as to cause a loss of  recoverability  of reserves and environmental
damage) or which is a novel  operation or is a novel use of an  operation  which
does not yet have general acceptance in the oil and gas industry unless required
due to an emergency risking life or property.

2.3      Budget

         The Manager  shall on or prior to November 30 of each year  prepare and
furnish to Abraxas for approval, a budget, setting forth the expected production
from its  respective  interests  in the Assets and the  expected  operating  and
capital  expenditures related to the Assets and containing such other matters as
should  properly  be included in such an annual  budget or as are  requested  by
Abraxas.

2.4      Disposition of Proceeds; Reports; Limitation of Authority

         Notwithstanding  that  Abraxas  may be named in any land and  Operating
Agreements  applicable  to the  Assets,  Abraxas  shall  direct all third  party
operators of the Assets to pay proceeds owing to Abraxas to the Manager.

         The Manager  shall  maintain a cash float (the "cash  float") as may be
agreed to by the Manager and Abraxas  from time to time.  The Manager may retain
revenues from time to time to maintain the cash float balance.

         Unless otherwise directed by Abraxas,  the Manager shall distribute all
net proceeds received by it in respect of the Assets, less the amounts necessary
to maintain the cash float,  on a monthly basis by the 15th day after the end of
each month in which such proceeds were received by Manager,  commencing December
15,  1996,  together  with a cash  reconciliation  and a  report  for the  month
immediately  preceding such month describing operations in respect of the Assets
for such  preceding  month,  which report  shall  include an  accounting  of all
revenues  and  expenses,  a general  description  of  operations  carried out in
respect of the Assets, a report on the sale price received for the production of
Petroleum  Substances from the Assets,  any  extraordinary  events affecting the
Assets, a description of any and all spills, leaks or discovery of environmental
damage caused by or affecting the Assets,  and any other  information  as may be
requested by Abraxas from time to time.

         The Manager  shall  promptly  notify  Abraxas  when it  discovers or is
advised  of any  significant  environmental  damage or  potential  environmental
damage affecting or caused by the Assets and shall, subject to consultation with
Abraxas,  take such action as it deems  necessary or desirable to deal with such
environmental damage in accordance with good oil and gas industry practice.

         Notwithstanding  anything  contained  herein,  the Manager shall not be
entitled to commit Abraxas to any expenditure for the account of Abraxas for any
single  operation the total  estimated  cost of which is in excess of $50,000 to
the account of Abraxas  other than  operating  costs  incurred  in the  ordinary
course of business,  without the prior direction of Abraxas, unless required due
to an emergency risking life or property.

         Where cash calls are made by the  Operator  pursuant  to the  Operating
Agreements,  the  Manager  shall  satisfy  such cash  calls out of the  proceeds
received  by the  Manager on account of  Abraxas,  and the cash float and to the
extent the  Manager  does not have  sufficient  monies of Abraxas to satisfy the
cash calls, the Manager shall timely notify Abraxas of the cash call and Abraxas
shall  deliver  to the  Manager  the  amount  of the cash call  within  the time
specified by the Manager in respect of such cash call.  The Manager  shall in no
event be required to lend any money to Abraxas.

2.5      Standard of Care

                  In exercising its powers and discharging its duties under this
agreement,  the Manager shall act in a manner determined by it to be in Abraxas'
best interest and shall exercise that degree of care, diligence and skill that a
reasonably  prudent  advisor and manager in respect of petroleum and natural gas
properties in Western Canada would exercise in comparable  circumstances.  It is
acknowledged  and  understood by the parties  hereto that the Manager may in its
capacity as advisor and manager  delegate  specific  aspects of its  obligations
hereunder to any corporation,  firm, person or other entity,  provided that such
obligation  shall not relieve the Manager of any of its  obligations  under this
agreement.

2.6      Manager as Operator

         Where the  Manager  is  required  to act as the  Operator  on behalf of
Abraxas,  it shall  operate in accordance  with the terms and  conditions of the
applicable Operating  Agreements.  In the event the Manager and Abraxas own 100%
of the  working  interest  in  Assets  not  otherwise  operated,  the  Operating
Procedure  shall  apply to them and the  Manager  shall  operate  such assets in
accordance with the Operating  Procedure;  provided that in the event there is a
conflict  between the Operating  Procedure and this  agreement,  this  agreement
shall prevail.



<PAGE>


2.7      Marketing of Petroleum Substances

         Subject to terms of the applicable Operating  Agreements,  the Manager,
unless Abraxas is taking produced Petroleum Substances in kind, shall market and
dispose of all Petroleum  Substances  produced from the Assets on such terms and
conditions as it shall determine satisfactory to it except where it is satisfied
with the  terms  of sale by the  third  party  operator  in which  case it shall
supervise the marketing and disposition of the Petroleum Substances as conducted
by the third party operator.  Notwithstanding  the foregoing,  the Manager shall
not enter into any sales contract without the written consent of Abraxas (i) for
oil having a term in excess of one year unless such  contract can be  terminated
on not greater than 60 days notice;  and (ii) for natural gas with volumes,  net
to Abraxas,  in excess of one million cubic feet per day having a term exceeding
one year,  unless the contract may be  terminated  by Abraxas at any time on not
greater than one year's notice to the applicable purchaser.

2.8      Taking in Kind

                  Subject  to  terms  of the  applicable  Operating  Agreements,
Abraxas  shall  have the  right to take its  share of the  Petroleum  Substances
produced from the Assets in kind and  separately  dispose of same and if Abraxas
chooses  to do so,  the  Manager  shall  promptly  supply  Abraxas  any  and all
information  required to  effectively  market and  dispose of Abraxas'  share of
Petroleum Substances.

                                    ARTICLE 3
                           MANAGER'S FEES AND EXPENSES

3.1      Reimbursable Costs

         Abraxas shall reimburse or pay the Manager for all reasonable costs and
expenses paid or to be paid by the Manager properly  attributable to Abraxas and
paid  directly to third  parties by or on behalf of Abraxas  including,  without
limitation,  all costs and expenses  relating to financial  accounting,  audits,
bank consulting services, legal, engineering and geological consulting services,
joint venture audits, land administration,  insurance and those duties for which
the Manager is obligated to arrange in clause 2.1 hereof. Where any services are
requested by Abraxas for its sole benefit,  Abraxas shall be solely  responsible
for such costs.  The Manager shall not be entitled to contract out services with
third parties  without the written  consent of Abraxas  unless such services are
not within the expertise of the Manager or are not services ordinarily conducted
by the Manager,  in which case the Manager will consult with and advise  Abraxas
of preferable third party service providers. Nothing herein shall be interpreted
as requiring the Manager to expend its own funds on behalf of Abraxas.

3.2      General and Administration Sharing

         It is the  intention of the parties that Abraxas  shall  reimburse  the
Manager for that proportion of the Manager's  general  overhead  attributable to
its management  expenses for the performance of its  obligations  hereunder (the
"Administrative Cost Amount"),  and no more. Abraxas shall pay to the Manager an
estimated annual  Administrative Cost Amount for the Manager's general overhead,
as determined below, payable in equal monthly  installments.  The Administrative
Cost Amount for each calendar year, or lesser period for any period in which the
Manager  provides  services  for less than a twelve (12) month period (such stub
period or twelve (12) month  period being  referred to as a "Period")  shall be,
unless  otherwise  agreed by the Manager and  Abraxas,  that  percentage  of the
general  and  administrative  costs  of  the  Manager  (excluding,  for  greater
certainty any corporate  costs relating to its corporate  existence,  compliance
with corporate and securities legislation,  costs of financing,  whether debt or
equity,  and costs of a similar  nature)  equivalent to that percentage that the
gross revenues  attributable to the Assets of Abraxas managed by the Manager are
of the aggregate  gross revenues of all assets managed by Cascade.  On or before
sixty (60) days  following  the  commencement  of any period,  the Manager shall
reasonably  and in good faith estimate the  Administrative  Cost Amount for such
period and notify  Abraxas of such  estimated  Administrative  Cost Amount.  The
estimated  Administrative  Cost  Amount  for  the  initial  period  shall  be as
determined by the Manager. For all subsequent periods, in the event Abraxas does
not agree with the Manager's  estimate and Abraxas and the Manager  cannot agree
on  an  estimated  Administrative  Cost  Amount  for  a  period,  the  estimated
Administrative  Cost  Amount  for such  period  shall be equal to the  estimated
Administrative  Cost  Amount for the  previous  period.  If at any time during a
period, the Manager or Abraxas determine that the estimated  Administrative Cost
Amount shall be materially  incorrect as a result of an event, the Manager shall
provide a new estimated  Administrative  Cost Amount and all subsequent  monthly
installments  of such  period  shall  be  adjusted  so  that  the  aggregate  of
installments to the Manager shall equal "to the revised estimated Administrative
Cost Amount".  As soon as possible after the end of each period, but in no event
no later than 140 days after the end of such period, the Manager shall cause its
auditors to calculate the actual general administrative costs and the percentage
allocated to the  performance  of its  obligations  hereunder  calculated as set
forth in this clause or as otherwise agreed by Abraxas and the Manager.  Abraxas
and the Manager shall make an  adjustment  based on the  difference  between the
amount  calculated by the auditor as the actual  Administrative  Cost Amount and
the estimated Administrative Cost Amount for such period. For greater certainty,
any fees received as overhead reimbursements under operating agreements shall be
deducted from the Manager's general and administrative  costs for the purpose of
calculating the Administrative Cost Amount pursuant hereto.

                                    ARTICLE 4
                            ACTIVITIES OF THE MANAGER

4.1      Other Activities

         The parties  hereto hereby  acknowledge  that the Manager is engaged in
and will continue to engage in the oil and gas business in Canada and elsewhere.
Accordingly, the Manager will divide its resources between its obligations under
this  agreement  and other  operations  in which  Abraxas  will not have,  or be
entitled to, any interest.  Such other  operations will include the acquisition,
disposition and exploitation of Canadian resource properties. The parties hereto
consent to such  activities and they agree that nothing herein shall prevent the
Manager or any of its officers,  directors or employees or any of its Affiliates
from having  other  business  interests or from  engaging in any other  business
activities  relating to  Canadian  resource  property  including  the  ownership
thereof.  In the event that the  interests  of the Manager are in conflict  with
those of Abraxas, the Manager shall notify Abraxas of such conflict and shall be
obliged  to make  decisions  acting  in good  faith,  having  regard to the best
interests  of such  parties  and in a  manner  that  would  not  contravene  the
obligations of the Manager to Abraxas.

4.2      Additional Information

         The  parties  hereto   acknowledge  that  exploration  and  development
activities on the Assets may have the incidental affect of providing  additional
information with respect to, or augmenting the value of, properties in which the
Manager or its  Affiliates  have an interest  and the parties  hereto agree that
neither the Manager nor its Affiliates shall be liable to account to any of them
with respect to such activities or results,  provided that the Manager shall not
act in a manner that would contravene its obligations to Abraxas.

4.3      Restrictions and Duties

         During the term of this agreement, the Manager shall:

         (a) unless otherwise  agreed,  not commingle its own funds or the funds
of any other persons with any funds held by it on behalf of Abraxas; and

         (b) not "step-up" any cost by reason of transactions  among  Affiliates
of the Manager and accordingly,  all costs charged to Abraxas will be the lowest
amount of costs incurred by the Manager or any Affiliate thereof.

4.4      No Liability for Advice

         The Manager shall not be liable, answerable or accountable for any loss
or damage  resulting from the advice given by the Manager or the exercise by the
Manager of a discretion or its refusal to exercise a  discretion,  provided that
the Manager has acted in a faithful,  diligent  and honest  manner and is not in
breach of any of its obligations hereunder.

                      ARTICLE 5 INDEMNIFICATION OF MANAGER

5.1      Indemnification

                  The Manager and any person who, at the request of the Manager,
is serving or shall  have  served as a  director,  officer  or  employee  of the
Manager shall be indemnified  by Abraxas  against all  liabilities  and expenses
(including judgments,  fines, penalties,  amounts paid in settlement and counsel
fees)  arising  from or  related  in any  manner to this  agreement,  unless the
liability or expenses (as described above) results from the willful misfeasance,
bad faith or gross negligence of the Manager or its Affiliates.

5.1      Indemnification

         The foregoing  right of  indemnification  shall not be exclusive of any
other  rights to which the Manager or any person  referred to in Section 5.1 may
be entitled as a matter of law or which may be lawfully granted to it.

                                    ARTICLE 6
                              TERM AND TERMINATION

6.1      Term

         The term of this agreement is for an initial term of  twenty-four  (24)
months from and including the date hereof (the  "Primary  Term") and  thereafter

trustee or assignee in bankruptcy in respect of all or any portion of its assets

         judging the Manager bankrupt or insolvent under any Canadian bankruptcy
law; or

         for the  appointment of a receiver or trustee or assignee in bankruptcy

a compromise or arrangement with creditors or claimants;

B. Abraxas may terminate  this  agreement on ten (10) days written notice in the
event that:

         the Manager  defaults in the  performance  of any material  obligations
under this agreement and has not remedied such default within 30 days of receipt
by the Manager of notice of such default from Abraxas or, where such default can
be remedied but not within 30 days,  promptly commenced to remedy and diligently

becomes a default.

6.4      Effect of Waiver

                  If a  default  has been  waived,  it shall be  deemed  for all
purposes never to have occurred and if a period of time has been extended,  such
extended  period  shall,  for all  purposes,  be deemed to have  begun  from the
beginning of such period  provided  that no waiver shall  constitute a waiver of
any subsequent default for non-performance.

6.5      Termination

                  Upon the effective date of termination of this agreement,  the
Manager shall forthwith:

         pay to or to the order of Abraxas all  monies,  if any,  collected  and

instruments and assurances as may be desirable or required to provide an orderly
transfer  of the duties and  responsibilities  of the  Manager to Abraxas or its
designee.

pursuant to clause 6.2, other than 6.2(B)(c),  Abraxas shall  compensate for any
financial commitments incurred by the Manager with the approval of Abraxas which
were  required to perform its duties  hereunder  which cannot be  terminated  on
