                        AUDITORS' REPORT TO THE DIRECTORS



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.

                                       8

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)




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.

         translation of long-term monetary  liabilities,  unless designated 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

Canadian Abraxas Petroleum Limited (a Canadian corporation)

      We have  audited  the  accompanying  balance  sheet  of  Canadian  Abraxas

                             NOTES TO BALANCE SHEET

                               September 30, 1996


1.  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.


2.  Subsequent Events (unaudited)

      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. The notes are redeemable, in whole or
in part, at the option of the Company and Abraxas  Petroleum  Corporation  on or
after  November 1, 2000, and any time prior to November 1, 1999, the Company and
Abraxas  Petroleum  Corporation may redeem up to 35% of the aggregate  principal
amount of the Notes with 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.
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.

                         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 the  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.

              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  Patricio  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.

                          Notes to Financial Statements
                                   (Unaudited)

                 Period From March 20, 1996 (Date of Formation)
                           Through September 30, 1996


1.  Organization and Significant Accounting Policies

Nature of Operations

Portilla-1996,  L.P., a Texas limited partnership  (Partnership),  was formed on
March 20, 1996. The  Partnership is an independent  energy  partnership  engaged
primarily  in the  production  of crude oil and natural gas along the Texas Gulf
Coast and in the Permian  Basin of western  Texas for sale into the U.S.  energy
market. The accompanying unaudited financial statements include all adjustments,
consisting of normal recurring adjustments,  that, in the opinion of management,
are  necessary  for a fair  presentation.  In  March,  1996,  Abraxas  Petroleum
Corporation  (Abraxas)  sold its 50% working  interest in its Portilla Field and
its 12% working interest in its Happy Field to ACCO, LLC (Limited Partner).  The
Limited Partner also obtained the release of a 50% overriding  royalty  interest
in the Portilla  Field  previously  owned by the  Commingled  Pension Trust Fund
(Pension Fund).

In connection  with the purchase of both Abraxas'  interests in the Portilla and
Happy Fields and the Pension Fund's  interest in the Portilla  Field  (together,
the  Properties),  the Limited  Partner  entered into a credit  agreement with a
bank,  secured  by  the  Properties,  and  contributed  the  Properties  to  the
Partnership.    A   subsidiary    of   Abraxas,    Portilla-Happy    Corporation
(Portilla-Happy), is the general partner of the Partnership.

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.



                                       30






1.  Organization and Significant Accounting Policies (continued)

Oil and Gas Properties

The  Partnership  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 Partnership does
not capitalize internal costs. 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.

Revenue Recognition

The Partnership  recognizes  crude oil and natural gas revenue from its interest
in producing wells as crude oil and natural gas is sold from those wells.

Deferred Financing Fees

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

Organization Costs

Organization costs are being amortized on a straight line basis over five years.

Income Taxes

The  Partnership  is not subject to federal  income  taxes;  rather,  its income
(loss) from operations is passed directly through to its partners.

2.  Partnership Formation and Agreement

In  connection  with the  formation  of the  Partnership,  the  General  Partner
contributed  cash  of  $2,000,000  and  the  Limited  Partner   contributed  the
Properties  and cash of  $80,000.  These  Properties  have been  recorded in the
Partnership's property and equipment at $27,500,000 representing the amount paid
by the  Limited  Partner for the  Properties.  No partner is  obligated  to make
additional contributions to the Partnership.

The Partnership agreement provides for cash to be distributed to the partners as
follows:

*  Until cumulative cash distributions have equaled the original contribution of

   $21,580,000  to the Limited  Partner and  $2,000,000 to the General  Partner,
   cash  in  excess  of  amounts  necessary  to pay  the  Partnership's  current
   obligations shall be distributed 91.5% to the Limited Partner and 8.3% to the
   General Partner, then






                                       31


2. Partnership Formation and Agreement (continued)

*  from the time that cumulative cash  distribution  equals the original capital
   contribution  until  the  operator  of the  Properties  is  entitled  to cash
   distribution  equal to a 25% net revenue  interest in the Properties with the
   remainder to the Limited Partner, and thereafter

*  the  operator  is  entitled  to a  percentage  of 43.75%  of the net  revenue
   interest in the  Partnership  Properties  with the  remainder  to the Limited
   Partner.

3. Long-Term Debt

In  connection  with the  Limited  Partner's  purchase  of the  interest  in the
Portilla  and Happy  Fields,  it  entered  into a credit  agreement  with a bank
providing  financing  in the amount of  $21,750,000.  The  borrowings  under the
credit  agreement  are  collateralized  by  the  Partnership's  interest  in the
Portilla  and Happy  Fields,  the Limited  Partner's  ownership  interest in the
Partnership,  the Partnership bank accounts and a guaranty  agreement.  Although
the bank  credit  agreement  is between the  Limited  Partner and the bank,  the
Partnership  has  recorded  the debt in its  financial  statements  because  the
Partnership  Properties  have been  pledged  as  collateral  for the  debt.  The
borrowings bear interest  generally at LIBOR or the bank's prime rate.  Under an
interest  rate swap  agreement,  the  interest  rate has been  fixed at 6.12% on
approximately  80% of the  outstanding  borrowings  through  October  31,  2001.
Principal  is due in monthly  installments  of 2.70% of the  original  principal
balance through April 1997,  2.00% through April 1998; 1.46% through April 1999,
1.29% through April 2009, .67% through April 2001 and .42% through October 2001.
The Partnership incurred financing fees of $273,000.

Notes payable consist of three  promissory  notes payable to private  investment
funds totaling $5,920,000.  Each note bears interest at 10%, is due on March 30,
2004 and can be prepaid without penalty after four years. The notes are recourse
to the Partners only to the extent of  distribution  made by the  Partnership to
such Partners. The Partnership has granted each noteholder an option to purchase
an overriding  royalty  interest in the  Partnership's  oil and gas  properties,
which will  entitle  the  noteholders,  on a combined  basis,  to 74% of the net
revenue  for the oil and gas  properties  through  the time that such  aggregate
royalty  payments  have  equaled  the sum of 10% of the  option  price per annum
compounded  annually and 150% of the option price; then at 56.25% of net revenue
until the termination of the royalty  interest.  The noteholder may apply to the
payment of the  purchase  price all or any part of the  principal  amount of the
promissory  notes from the  Partnership  and any  accrued  and  unpaid  interest
thereon on a  dollar-for-dollar  basis. The portion of the purchase price not so
applied  shall be paid in cash.  The option can be  exercised  at any time until
April 30, 2004.

As of  September  30,  1996,  the private  investment  funds had advanced to the
Partnership $538,000 for working capital purposes.


4. Advisory and Operating Agreements

The Partnership has entered into an advisory agreement with an entity related to
the  Limited  Partner to  provide  various  advisory  services  relating  to the


                                       32



identification  and  acquisition  of oil and gas  properties,  the  marketing of
production,  the monitoring of costs by the operator and  preparation of reports
and all material financial matters related to the Partnership or its oil and gas
properties.  Such  advisor is entitled to  quarterly  compensation  equal to the
lesser of 1/4 of 1% of the debt  payable  to the  investment  funds or 1% of the
partnership  gross  proceeds  plus  reimbursement  of  reasonable  out-of-pocket
expenses incurred in rendering its services.  For the period ended September 30,
1996, the Partnership  accrued $42,000  related to the advisory  agreement,  the
payable of which is included in accounts payable.

The parent Company of the General Partner,  Abraxas,  is the operator of the oil
and gas  properties  of the  Partnership  and also provides  certain  executive,
administrative, legal, and accounting support to the Partnership for which it is
not reimbursed.

During the period ended  September 30, 1996, as operator,  Abraxas has collected
net  revenues  from  the  sale  of oil  and  gas  production  on  behalf  of the
Partnership.  Abraxas has also advanced funds on behalf of the  Partnership  for
development drilling and working capital purposes. As of September 30, 1996, the
Partnership has recorded a net payable to Abraxas of $398,000 for such activity.

The Partnership  agreement  provides that the General Partner shall have all the
rights and powers of a General  Partner except the Limited  Partner must approve
in writing any transfer of the oil and gas  properties,  any  acquisition of any
other mineral  property,  the lending of money or the guarantee of  obligations,
and any material  amendment of an operating  agreement.  The Limited Partner may
remove the General Partner upon 60 days written notice.

5. Commodity Swap Agreement

In April 1996, the Partnership  entered into a commodity swap agreement with its
bank lender to reduce its exposure to price risk in the spot  market.  Under the
commodity swap agreement, the Partnership receives or makes payments to the bank
based on the differential between a fixed and variable price for natural gas. At
September 30, 1996, the Partnership had agreed to exchange  payments  monthly on
volumes  ranging from 8,160 to 20,000  barrels of crude oil per month and 14,850
to 87,406 MMBTU of natural gas per month extending  through November 2001. Under
the swap agreement, the Partnership receives fixed prices ranging from $17.20 to
$18.55 per barrel of crude oil and $1.793 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.

6. Subsequent Event

In November,  1996,  Abraxas acquired the Limited  Partner's 75% interest in the
Partnership and repaid the bank debt as well as the notes payable to the private
investment  funds  resulting  in  Abraxas  effectively  owning all of the equity
interests in the  Partnership.  Upon the  acquisition  of the Limited  Partner's
interest, Abraxas had title to the Properties transferred to its name.

                         PRO FORMA FINANCIAL INFORMATION

      The  following  unaudited  pro forma  financial  data are derived from the
historical financial statements of Abraxas Petroleum  Corporation  (Company) and
are adjusted to reflect the  consummation  of the  acquisitions of CGGS Canadian
Gas Gathering  Systems,  Inc. (CGGS) by Canadian  Abraxas  Petroleum  Limited (a
wholly owned subsidiary of Abraxas Petroleum Corporation) (Canadian Abraxas) and
of Certain  Overriding  Royalty  Interests  in the  Portilla  Field  acquired by
Abraxas  Petroleum  Corporation  which were  previously  owned by the Commingled
Pension Trust Fund (Pension Fund) (the  Acquisitions) and also reflects the sale
of  $215,000,000,  11.5% Senior Notes due 2004 (Notes) and the  repayment of all
amounts  outstanding  under the Credit  Agreement  dated September 30, 1996 with
Bankers  Trust Company and other  lenders in the amount of  $85,000,000  (Credit
Agreement). The pro forma statements of operations also reflects the acquisition
of the oil and gas producing properties acquired from Enserch Exploration,  Inc.
on September 30, 1996 (Wyoming Properties).  The historical balance sheet of the
Company at  September  30, 1996  includes  the  acquisition  cost of the Wyoming
Properties.

      The  Unaudited  Pro Forma  Condensed  Balance  Sheet of the  Company as of
September 30, 1996 has been prepared  assuming the  Acquisitions,  sale of Notes
and repayment of the Credit  Agreement  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  Acquisitions,  sale of Notes and repayment of the Credit
Agreement were consummated on January 1, 1995 and January 1, 1996, respectively.
The  historical  revenues and expenses of CGGS and Portilla and Happy  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 five-month period. The historical
financial  statements of CGGS include the results of the Hoole Area. In January,
1997,  Canadian  Abraxas entered into a letter of intent to sell its interest in
the  Hoole  Area for  approximately  $9.3  million.  For the nine  months  ended
September 30, 1996, the Hoole Area properties and natural gas processing  plants
contributed $2.4 million of revenues to CGGS.

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

                                       34


      The unaudited pro forma  Condensed  Balance Sheet reflects the preliminary
allocations  of the  purchase  prices  for the  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  purchase  prices  allocated  to assets  and
liabilities  on the  basis  if the  estimated  fair  values  of the  assets  and
liabilities  determined  at the  end of the  allocation  period  as  allowed  by
accounting Principles Board Opinion Number 38.

      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 relating to
CGGS and the Certain Overriding Royalty Interests in the Portilla Field acquired
by Abraxas Petroleum Corporation included herein.

                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  Acquisitions,  the sale of
Notes and repayment of the Credit Agreement as if consummated on January 1, 1995
and January 1, 1996,  respectively.  The statements  also reflect the operations
relating to the acquisition of the oil and gas properties  acquired from Enserch
Exploration, Inc. on September 30, 1996 (Wyoming Properties).

a. To adjust for the sale of the Nevis Plant prior to the Company's  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 50% overriding royalty interest in Portilla  previously
owned by the Pension Fund and the Wyoming Properties 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  reacquisition of Portilla and
Happy for the period March 21, 1996 to September 30, 1996,  the  acquisition  of
the 50% overriding  royalty  interest in the Portilla Field  previously owned by
the Pension Fund and the Wyoming  Properties 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:

                                                                   Nine Months

Note 2. The pro forma  unaudited  Condensed  Balance  Sheet as of September  30,
1996,  reflects the Acquisitions,  the sale of Notes and repayment of the Credit
Agreement as if they had occurred as of September 30, 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 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.

      Acco  entered  into a  commodity  price hedge with  Christiania  which was
assumed by the Company 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 Christiania  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.
