                             Summary of the Offering

principal amount of the second lien notes, 163,354 shares of Abraxas common

                        Summary of the Second Lien Notes

Amount Offered............................  11 1/2% Senior Secured Notes due
                                            2004, Series A, with principal
                                            amount of up to $5.0 million.

Issuers...................................  Abraxas Petroleum Corporation and
                                            Canadian Abraxas Petroleum Limited.

Maturity Date.............................  November 1, 2004.

Interest Rate and Payment Dates...........  Annual rate - 11 1/2%.

                                            Payment frequency -- every six
                                            months on May 1 and November 1.

                                            First payment -- May 1, 2000.


Guarantees................................  Each guarantor is Abraxas'
                                            wholly-owned subsidiary. If the
                                            issuers cannot make payments on the
                                            second lien notes when they are due,
                                            the guarantors must make them
                                            instead.


Ranking...................................  The second lien notes and the
                                            guarantees constitute senior debts.

                                            They  rank  equally  with all of the
                                            issuers'   and   each    guarantor's
                                            current  and  future   indebtedness.
                                            They   are,   however,   effectively
                                            subordinated to the first lien notes
                                            and related guarantees to the extent
                                            the value of the collateral securing
                                            the second  lien  notes and  related
                                            guarantees  and the first lien notes
                                            and    related     guarantees     is
                                            insufficient  to pay both the second
                                            lien notes and the first lien notes.

Collateral................................  The second lien notes are secured by
                                            a second lien or charge on
                                            substantially all of our proved
                                            crude oil and natural gas properties
                                            and natural gas processing plants
                                            and the shares of Grey Wolf common
                                            stock owned by us. Holders of the
                                            second lien notes may not foreclose
                                            on the collateral for 180 days after
                                            an event of default under the second
                                            lien notes.

Optional Redemption.......................  On or after December 1, 2000, the

                                            certain  public  offerings of equity

Mandatory Offer to Repurchase............   If the issuers sell certain assets
                                            or experience specific kinds of
                                            changes of control, the issuers must
                                            offer to repurchase the second lien
                                            notes, subject to certain
                                            limitations in the case of assets
                                            sales, at the prices listed in the
                                            section "Description of the Second
                                            Lien Notes."

Basic Covenants of the Indenture..........  The issuers issued the second lien
                                            notes under an indenture with
                                            Firstar Bank, National Association.
                                            The indenture, among other things,
                                            restricts the issuers' ability and
                                            the ability of their subsidiaries
                                            to:

                                               o borrow money or issue preferred
                                               stock;
                                               o pay dividends on stock or
                                               purchase stock;
                                               o pay dividends or make other
                                               asset transfers;
                                               o transact business with
                                               affiliates;
                                               o sell stock in subsidiaries;
                                               o engage in any new line of
                                               business;
                                               o impair the security interest in
                                               any collateral for the new notes;
                                               o use assets as security in other
                                               transactions; and
                                               o sell certain assets or merge
                                               with or into other companies.



                                The Common Stock


         Abraxas is authorized to issue a total of 50,000,000 shares of common
stock, par value $.01 per share, and 1,000,000 shares of preferred stock, par
value $.01 per share. As of February 9, 2000, there were 22,747,118 shares of
Abraxas common stock outstanding and no shares of preferred stock outstanding.


                           The Contingent Value Rights


         Abraxas has issued contingent value rights or CVRs which may entitle
the holders thereof to receive up to a total of 105,408,978 shares of Abraxas
common stock. On December 21, 2000, or at the election of Abraxas, on May 21,
2001, Abraxas may be required to issue additional shares of common stock to the
holders of the contingent value rights. The actual number of shares issued will
depend on the market price of Abraxas common stock. The CVRs will terminate if
the market price of Abraxas common stock exceeds certain target prices for a
period of 30 trading days during any 45 consecutive trading day period prior to
the expiration date. The target price on any given date will equal $5.03 plus
                                       6
<PAGE>
daily interest at an annual rate of 11.5%. On December 21, 2000, the target
price will be $5.68 and on May 21, 2001, the target price will be $5.97. If the
number of shares ultimately issuable under the CVRs is greater than the number
of authorized and unissued shares we have available at that time, we will be
required either to increase the authorized number of shares of Abraxas common
stock or to effect a reverse stock split in order to increase the number of
authorized and unissued shares of Abraxas common stock to an amount sufficient
to satisfy the number of shares issuable under the CVRs.

                           FORWARD-LOOKING INFORMATION

    We make forward-looking statements throughout this prospectus. Whenever you
read a statement that is not simply a statement of historical fact (such as when
we describe what we "believe," "expect" or "anticipate" will occur, and other
similar statements), you must remember that our expectations may not be correct,
even though we believe they are reasonable. We do not guarantee that the
transactions and events described in this prospectus will happen as described
(or that they will happen at all). The forward-looking information contained in
this prospectus is generally located in the material set forth under the
headings "Summary," "Risk Factors," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business" but may be found
in other locations as well. These forward-looking statements generally relate to
our plans and objectives for future operations and are based upon our
management's reasonable estimates of future results or trends. The factors that
may affect our expectations of our operations include, among others, the
following:

         o  Our lack of liquidity
         o  Our high debt level
         o  Economic and business conditions
         o  Our success in completing acquisitions or in development and
            exploration activities
         o  Prices for crude oil and natural gas; and
         o  Other factors discussed under "Risk Factors" or elsewhere in this
            prospectus.

                                  RISK FACTORS

         You should carefully consider the following risk factors in addition to
the other information in this prospectus before making an investment in the
second lien notes, Abraxas common stock and contingent value rights offered by
the selling security holders.


                          Risks Related to the Offering

We can not assure you that an active market will develop for the second
lien notes, the Abraxas common stock or CVRs.

         The second lien notes and CVRs have recently been issued and we cannot
assure you that an active market will develop, or, if such a market develops,
that such market will be liquid. The second lien notes and CVRs will not be
listed on any national securities exchange. Accordingly, we cannot assure you
that a holder of the second lien notes or the CVRs will be able to sell such
second lien notes or the CVRs in the future or as to the price at which such
sale may occur. The liquidity of the market for the second lien notes and CVRs
and the prices at which such second lien notes and CVRs trade will depend upon
the amount outstanding, the number of holders thereof, the interest of
securities dealers in maintaining a market in such second lien notes and CVRs
and other factors beyond our control.

         The liquidity of, and trading market for, the second lien notes also
may be adversely affected by general declines in the market for high yield
securities. Such declines may adversely affect the liquidity and trading markets
for the second lien notes.

         The Abraxas common stock is quoted on the OTC Bulletin Board. While
there are currently 14 market makers in the Abraxas common stock, none of these
market makers are obligated to continue to make a market in the Abraxas common
stock. In this event, the liquidity of the Abraxas common stock could be
adversely impacted and a stockholder could have difficulty obtaining accurate
stock quotes.

We have not paid dividends on the Abraxas Common Stock.

         Abraxas has never paid a cash dividend on its common stock and the
terms of the first lien notes indenture and the second lien notes indenture
limit the ability of Abraxas to pay dividends on its common stock.


Our ability to service our debt is limited by factors beyond our control.

         Our ability to meet our debt obligations and to reduce our
indebtedness, including the first lien notes, any outstanding old notes and the
second lien notes, will depend on our future performance. Our performance, to a
                                       9
<PAGE>
certain extent, is subject to general economic conditions and financial,
business and other factors that are beyond our control. Based upon the current
level of operations and the historical production of the producing properties
and related assets currently owned by us and the reduction in our indebtedness
as a result of the exchange offer, we believe that our current cash reserves and
cash flow from operations will be adequate to meet our anticipated requirements
for working capital, capital expenditures, interest payments, scheduled
principal payments and general corporate or other purposes for 2000. We cannot
assure you however, that we will continue to generate cash flow from operations
at or above current levels, that we will be able to meet our interest payments
on all of our debt or that the historical production of the producing properties
and related assets currently owned by us can be sustained in the future. Our
cash flow from operations will be negatively affected by, among other things,
depressed commodity prices. Further, our operating cash flow could be negatively
affected by our limited ability, due to our diminished liquidity and ability to
borrow funds, to acquire producing properties, to undertake exploration and
development projects and to otherwise replenish our depleting reserves.

         If we are unable to generate cash flow from operations in the future to
service the first lien notes, any outstanding old notes, the second lien notes
and our other debt, we may try to refinance all or a portion of our debt or
repay such debt with the proceeds of an equity offering. We cannot assure you
that we will be able to generate sufficient cash flow to pay the interest on our
debt or that future borrowings or equity financing will be available to pay or
refinance our debt. Our ability to refinance all or a portion of our debt or to
obtain additional financing will be substantially limited under the terms of the
first lien notes indenture, and the second lien notes indenture. Also,
substantially all of our crude oil and natural gas properties and natural gas
processing facilities are subject to a lien or floating charge for the benefit
of the holders of the first lien notes and are subject to a second lien or
floating charge for the benefit of the holders of the second lien notes. In
addition, the first lien notes, the old notes, and the second lien notes are
subject to certain limitations on redemption. You should read the discussions
under the heading "-- We Lack Liquidity Due to Our Reduced Cash Flow" and
"Description of the Second Lien Notes -- Redemption" for more information
regarding the factors which may limit our ability to service our debt, to redeem
the first lien notes, any outstanding old notes and the second lien notes and to
refinance our debt.

The security for the second lien notes may be inadequate to satisfy all amounts
due and owing under the first lien notes and the second lien notes.

         The second lien notes are secured by a second lien or charge on
substantially all of our proved crude oil and natural gas assets, natural gas
processing plants and Grey Wolf stock owned by us. There can be no assurance
that, following an acceleration after an event of default under the second lien
notes indenture, the proceeds from the sale of the collateral and allocable to
the second lien notes would be sufficient, either alone or when combined with
proceeds from the sale of other assets not constituting collateral and allocable
to the second lien notes, to satisfy all amounts due on the second lien notes.
The ability of the holders of second lien notes to realize upon the collateral
is also subject to certain limitations in the second lien notes indenture, the
accompanying mortgage and the pledge agreement, including a prohibition on
foreclosing on the collateral for 180 days after an event of default under the
second lien notes. In addition, if we become a debtor in a case under the United
States Bankruptcy Code (the "Bankruptcy Code"), the automatic stay imposed by
the Bankruptcy Code would prevent the Trustee from selling or otherwise
disposing of the collateral without bankruptcy court authorization. In that
case, the foreclosure might be delayed indefinitely. You should read the
discussion under the heading "Description of the Second Lien Notes -- Security"
for more information regarding the rights of holders of the second lien notes to
the collateral.

The guarantees may not be enforceable in bankruptcy.

         Abraxas' and Canadian Abraxas' obligations under the second lien notes
are guaranteed by Sandia and Wamsutter. Various fraudulent conveyance laws have
been enacted for the protection of creditors and may be utilized by courts to
subordinate or void such guarantees. It is also possible that under certain
circumstances a court could hold that the direct obligations of a guarantor
could be superior to the obligations under its guarantee.

         To the extent that a court were to find that at the time a guarantor
entered into a guarantee either:

         (1)  the guarantee was incurred by the guarantor with the intent to
              hinder, delay or defraud any present or future creditor or that
              the guarantor contemplated insolvency with a design to favor one
              or more creditors to the exclusion in whole or in part of others,
              or
                                       10
<PAGE>
         (2)  the guarantor did not receive fair consideration or reasonably
              equivalent value for issuing the guarantee and, at the time it
              issued the guarantee, the guarantor

              o   was insolvent or rendered insolvent by reason of the issuance
                  of the guarantee,

              o   was engaged or about to engage in a business or transaction
                  for which the remaining assets of the guarantor constituted
                  unreasonably small capital or

              o   intended to incur, or believed that it would incur, debts
                  beyond its ability to pay such debts as they matured,

the court could void or subordinate the guarantee in favor of the guarantor's
other creditors. Among other things, a legal challenge of a guarantee issued by
a guarantor on fraudulent conveyance grounds may focus on the benefits, if any,
realized by the guarantor as a result of our issuance of the second lien notes.
A court might find that the guarantors did not benefit from incurrence of the
indebtedness represented by the second lien notes.

         To the extent that a guarantee is voided as a fraudulent conveyance or
found unenforceable for any other reason, holders of the second lien notes would
cease to have any claim in respect of the applicable guarantor. In such event,
the claims of the holders of the second lien notes against such guarantor would
be subject to the prior payment of all liabilities and preferred stock claims of
such guarantor. There can be no assurance that, after providing for all claims
and preferred stock interests, if any, there would be sufficient assets to
satisfy the claims of the holders of the second lien notes relating to any
voided portion of such guarantee.

         Under applicable provisions of Canadian federal bankruptcy law or
comparable provisions of provincial fraudulent preference laws, if a court in an
action brought by an unpaid creditor of Canadian Abraxas or by a bankruptcy
trustee of Canadian Abraxas were to find that the liens granted by Canadian
Abraxas over its assets were intended to prefer the holders of the second lien
notes over other creditors, such liens could be set aside. This would become an
issue if Canadian Abraxas became insolvent or bankrupt within a certain period
after granting the liens.

Under certain circumstances a bankruptcy court could order the repayment of
interest payments made under the second lien notes or under the security
interests.

         The bankruptcy code allows the bankruptcy trustee (or us, acting as
debtor-in-possession) to avoid certain transfers of a debtor's property as a
"preference." Under the bankruptcy code a preference is:

o        a transfer of the debtor's property,

o        to or for the benefit of a creditor on account of an existing debt,

o        made while the debtor was insolvent (presumed in the 90 days before a
         bankruptcy filing),

o        if the creditor receives more than it would have received in a
         bankruptcy liquidation if the transfer had not been made, and

o        if the transfer/payment was made in the 90 days before the bankruptcy
         filing, or, if the creditor was an "insider" within one year before the
         bankruptcy filing (a creditor that is also a director, officer or
         controlling stockholder of a debtor may be deemed to be an insider).

         Our payment of principal and/or accrued interest, or our grant of a
lien or security interest, including payments made or liens or security
interests granted pursuant to the exchange offer, may be deemed to be a
preference if all of the factors discussed above are present. If such transfers
were deemed to be preferential transfers, the payments could be recovered from
the noteholders and the lien or security interest could be avoided.

         If the second lien notes are fully secured (i.e., the value of
collateral exceeds the amount it secures, including the first lien notes),
payments on the second lien notes would not constitute preferential transfers.
                                       11
<PAGE>
However, if, or to the extent, the second lien notes are undersecured (i.e., the
value of the collateral is less than the amount which it secures), payments
would be deemed to have been applied, first, to the unsecured portion of the
second lien notes and, second, to the secured portion of the second lien notes
and the payments attributable to the unsecured portion could be considered
preferential transfers. Therefore, if we are involved in a bankruptcy
proceeding, holders of second lien notes may be required to disgorge payments
made on the second lien notes to the extent such second lien notes are
undersecured.

         Additionally, due to Abraxas', Canadian Abraxas' and the Guarantors'
being domiciled in Canada and in the United States, Abraxas, Canadian Abraxas
and the Guarantors could be subject to multi-jurisdictional insolvency
proceedings in Canada and the United States. If multi-jurisdictional insolvency
proceedings were to occur, this could result in additional delay in payment of
the first lien notes or the second lien notes, as well as delay in or prevention
from enforcing remedies under the first lien notes or the second lien notes, any
guarantee thereunder and the liens securing the first lien notes or the second
lien notes and the guarantees. Likewise, the first lien notes or the second lien
notes could be subject to different treatment inasmuch as the multiple
insolvency proceedings would be conducted by different courts applying different
laws.

We may not be able to finance a change of control offer.

         Upon the occurrence of certain kinds of change of control events, we
will be required to offer to repurchase all of the first lien notes, any
outstanding old notes and the second lien notes. However, it is possible that we
will not have sufficient funds at the time of the change of control to make the
required repurchase of such notes.

                          Risks Related to Our Business


We lack liquidity due to our reduced cash flow.

         We have historically funded our operations primarily through cash flow
from operations and borrowings under our bank credit facilities and other credit
sources. Due to severely depressed crude oil and natural gas market prices, our
cash flow from operations in 1998 was substantially reduced. In 1999, our sale
of the first lien notes, the production payment to Southern and certain non-core
properties together with cash generated by operations provided us with the
liquidity necessary to service our debt and pay operating expenses. We
anticipate that we will have two principal sources of liquidity during the next
12 months: (i) cash on hand and (ii) cash generated by operations. You should
read the discussions under the heading "-- Lack of Liquidity," "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources," "Description of the Second Lien Notes," the
unaudited Pro Forma Financial Information and the notes thereto and the
Consolidated Financial Statements and the notes thereto included elsewhere in
this prospectus for more information regarding our indebtedness.

         Our ability to raise funds through additional indebtedness will be
substantially limited by the terms of the indenture governing the first lien
notes, the indenture governing the old notes and the indenture governing the
second lien notes, although many of the restrictive covenants contained in the
indenture governing the old notes were eliminated in connection with the
exchange offer.

         The first lien notes indenture and the second lien notes indenture
restrict, among other things, our ability to:

o        incur additional indebtedness
o        incur liens
o        pay dividends or make certain other restricted payments
o        consummate certain asset sales
o        enter into certain transactions with affiliates
o        merge or consolidate with any other person; or


o        sell, assign, transfer, lease, convey or otherwise dispose of all or
         substantially all of our assets.


         Additionally, our ability to raise funds through additional
indebtedness will be limited because substantially all of our crude oil and
natural gas properties and natural gas processing facilities are subject to a
lien or floating charge for the benefit of the holders of the first lien notes
and a second lien or floating charge for the benefit of the holders of the
second lien notes. We may also choose to issue equity securities or sell certain
of our assets to fund our operations, although the first lien notes indenture
and the second lien notes indenture will substantially limit our use of the
proceeds of any such asset sales. Because of our diminished cash flow from
operations and the resulting depressed prices for our common stock, we may not
be able to obtain equity financing on satisfactory terms.
                                       12
<PAGE>
         We have implemented a number of measures to conserve our cash
resources, including reducing our capital expenditures. However, while these
measures have helped to conserve our cash resources in the near term, they also
have limited our ability to replenish our depleting reserves. This could
negatively impact our operating cash flow and results of operations in the
future. You should read the discussion under the heading "-- Our Ability to
Replace Production with New Reserves Is Highly Dependent On Acquisitions or
Successful Development and Exploration Activities Which In Turn Are Adversely
Affected By Our Reduced Capital Expenditures" for more information.

Our debt levels and our debt covenants may limit our ability to pursue business
opportunities and to obtain additional financing.

         We have substantial indebtedness and debt service requirements. Our
total debt and stockholders' equity (deficit) were $346.2 million and $(75.3)
million, respectively, as of September 30, 1999, and $269.6 million and $2.0
million on a pro forma basis as of September 30, 1999. You should read the
discussion under the heading "Capitalization" for more information regarding our
high degree of leverage. We may incur additional indebtedness in the future in
connection with acquiring, developing and exploiting producing properties,
although our ability to incur additional indebtedness is substantially limited
by the terms of the first lien notes indenture and the second lien notes
indenture. You should read the discussions under the heading "-- We Lack
Liquidity Due to Our Reduced Cash Flow," "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources," "Description of the Second Lien Notes," the unaudited Pro Forma
Financial Information and the notes thereto and the Consolidated Financial
Statements and the notes thereto included elsewhere in this prospectus for more
information regarding our indebtedness.

         Our high level of debt affects our operations in several important
ways, including:

         o    A substantial amount of our cash flow from operations will be used
              to pay interest on the first lien notes, any outstanding old notes
              and the second lien notes;

         o    The covenants contained in the first lien notes indenture and the
              second lien notes indenture will limit our ability to borrow
              additional funds or to dispose of assets and may affect our
              flexibility in planning for, and reacting to, changes in our
              business, including possibly limiting acquisition activities;

         o    Our debt level may impair our 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; and

         o    The terms of the first lien notes indenture, the old notes
              indenture and the second lien notes indenture will permit the
              holders of the first lien notes, any outstanding old notes and the
              second lien notes to accelerate payments upon an event of default
              or a change of control.


Our ability to replace production with new reserves is highly dependent on
acquisitions or successful development and exploration activities which in turn
are adversely affected by our reduced capital expenditures.

         Our 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. We cannot assure you that such divestitures will
continue or that we will be able to acquire such properties at acceptable prices
or develop additional reserves in the future. In addition, under the terms of
the first lien notes indenture, the old notes indenture and the second lien
notes indenture, our ability to obtain additional financing in the future for
acquisitions and capital expenditures will be limited.
                                       13
<PAGE>
Crude oil and natural gas price declines and their volatility could adversely
affect our revenue, cash flows and profitability.

         Our revenue, profitability and future rate of growth depend
substantially upon prevailing prices for crude oil and natural gas. Crude oil
and natural gas prices fluctuate and in recent years have declined
significantly. Prices also affect the amount of cash flow available for capital
expenditures and our ability to borrow money or raise additional capital. In
1998 we reduced our capital expenditures budget because of lower crude oil and
natural gas prices. In addition, we may have ceiling test writedowns when prices
decline. Lower prices may also reduce the amount of crude oil and natural gas
that we can produce economically.

         We enter into hedge agreements and other financial arrangements at
various times to attempt to minimize the effect of crude oil and natural gas
price fluctuations. We cannot assure you that such transactions will reduce risk
or minimize the effect of any decline in crude oil or natural gas prices. Any
substantial or extended decline in oil or natural gas prices would have a
material adverse effect on our business and financial results. Hedging
activities may limit the risk of declines in prices, but such arrangements may
also limit additional revenues from price increases. You should read the
discussion under the heading "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Liquidity and Capital Resources -
Hedging Activities" for more information regarding our hedging activities.

Lower crude oil and natural gas prices increase the risk of ceiling limitation
writedowns.

         We use the full cost method to account for our crude oil and natural
gas operations. Accordingly, we capitalize the cost to acquire, explore for and
develop crude oil and natural gas properties. Under full cost accounting rules,
the net capitalized cost of crude oil and natural gas properties may not exceed
a "ceiling limit" which is based upon the present value of estimated future net
cash flows from proved reserves, discounted at 10%, plus the lower of cost or
fair market value of unproved properties. If net capitalized costs of crude oil
and natural gas properties exceed the ceiling limit, we must charge the amount
of the excess to earnings. This is called a "ceiling limitation writedown." This
charge does not impact cash flow from operating activities, but does reduce our
stockholders' equity. The risk that we will be required to write down the
carrying value of crude oil and natural gas properties increases when crude oil
and natural gas prices are low or volatile. In addition, writedowns may occur if
we experience substantial downward adjustments to our estimated proved reserves
or if purchasers cancel long-term contracts for our natural gas production. In
1998, we recorded a writedown of $61.2 million. We cannot assure you that we
will not experience ceiling limitation writedowns in the future. 14

Estimates of our proved reserves and future net revenue are uncertain and
inherently imprecise.

         This prospectus contains estimates of our proved crude oil and natural
gas reserves and the estimated future net revenue from such reserves. The
process of estimating crude oil and natural gas reserves is complex and involves
decisions and assumptions in the evaluation of available geological,
geophysical, engineering and economic data. Therefore, these estimates are
imprecise.


         Actual future production, crude oil and natural gas prices, revenues,
taxes, development expenditures, operating expenses and quantities of
recoverable crude oil and natural gas reserves most likely will vary from those
estimated. Any significant variance could materially affect the estimated
quantities and present value of reserves set forth in this prospectus. In
addition, we may adjust estimates of proved reserves to reflect production
history, results of exploration and development, prevailing crude oil and
natural gas prices and other factors, many of which are beyond our control.

         You should not assume that the present value of future net revenues
referred to in prospectus is the current market value of our estimated crude oil
and natural gas reserves. In accordance with SEC requirements, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the end of the year of the estimate. Actual future prices
and costs may be materially higher or lower than the prices and costs as of the
end of the year of the estimate. Significant declines during 1998 in crude oil
and natural gas prices reduced our present value of future net revenues. Any
changes in consumption by natural gas purchasers or in governmental regulations
or taxation will also affect actual future net cash flows. The timing of both
the production and the expenses from the development and production of crude oil
and natural gas properties will affect the timing of actual future net cash
flows from proved reserves and their present value. For example, we reduced our
1999 capital expenditure budget. This reduction will delay cash flows and
thereby reduce present value. In addition, the 10% discount factor, which is
required by the SEC to be used in calculating discounted future net cash flows
for reporting purposes, is not necessarily the most accurate discount factor.
The effective interest rate at various times and the risks associated with us or
the crude oil and natural gas industry in general will affect the accuracy of
the 10% discount factor.

         The estimates of our reserves are based upon various 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 December 31, 1998. The average sales prices as of such date used
for purposes of such estimates except for New Cache were $9.95 per Bbl of crude
oil, $8.97 per Bbl of NGLs and $1.90 per Mcf of natural gas and the average
sales prices used for purposes of such estimate of New Cache were $10.42 per Bbl
of crude oil and $1.47 per Mcf of natural gas. It is also assumed that New Cache
will make future capital expenditures of approximately $0.8 million in the
aggregate, which are necessary to develop and realize the value of proved
undeveloped reserves on its properties. Any significant variance in actual
results from these assumptions could also materially affect the estimated
quantity and value of reserves set forth herein.


We have experienced recurring net losses.

         The following table shows the losses we had in 1994, 1995, 1997, 1998
and the first nine months of 1999:

    You should read the discussions under the heading "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and our
Consolidated Financial Statements and the notes thereto included elsewhere in
this prospectus for more information regarding these losses. We cannot assure
you that we will become profitable in the future.

Our Canadian operations are subject to the risks of currency fluctuations and in
some instances economic and political developments.

         We have significant operations in Canada. The expenses of such
operations are payable in Canadian dollars while most of the revenue from crude
oil and natural gas sales is based upon U.S. dollar price indices. As a result,
Canadian operations are subject to the risk of fluctuations in the relative
values of the Canadian and U.S. dollars. We are also required to recognize
foreign currency translation gains or losses related to the debt issued by our
Canadian subsidiary because the debt is denominated in U.S. dollars and the
functional currency of such subsidiary is the Canadian dollar. Our foreign
operations may also be adversely affected by local political and economic
developments, royalty and tax increases and other foreign laws or policies, as
well as U.S.

policies affecting trade, taxation and investment in other countries.


We depend on our key personnel.

         We depend to a large extent on Robert L.G. Watson, our Chairman of the
Board, President and Chief Executive Officer, for our management and business
and financial contacts. The unavailability of Mr. Watson would have a materially
adverse effect on our business. Mr. Watson has a three-year employment contract
with Abraxas which provides that he can be terminated for cause only. Our
success is also dependent upon our ability to employ and retain skilled
technical personnel. While we have not experienced difficulties in employing or
retaining such personnel, our failure to do so in the future could adversely
affect our business.

Anti-takeover provisions could make a third party acquisition of Abraxas
difficult.

         Abraxas' articles of incorporation and by-laws provide for a classified
board of directors, with each member serving a three-year term and eliminate the
ability of stockholders to call special meetings or take action by written
consent. Abraxas has also adopted a stockholder rights plan. Each of the
provisions in the articles of incorporation and by-laws and the stockholder
rights plan could make it more difficult for a third party to acquire Abraxas
without the approval of Abraxas' board. In addition, the Nevada corporate
statute also contains certain provisions which could make an acquisition by a
third party more difficult. You should read the discussions under the heading
"Description of Capital Stock -- Anti-takeover Effects of Certain Provisions of
the Articles of Incorporation and Bylaws," "--Stockholders Rights Plan" and "--
Anti-Takeover Statutes" for more information regarding these anti-takeover
provisions.

                          Risks Related to Our Industry


Our operations are subject to numerous risks of crude oil and natural gas
drilling and production activities.

         Crude oil and natural gas drilling and production activities are
subject to numerous risks, many of which are beyond our control. These risks
include the following:

         o    that no commercially productive crude oil or natural gas
              reservoirs will be found;

                                       16
<PAGE>

         o    that crude oil and natural gas drilling and production activities
              may be shortened, delayed or canceled; and

         o    that our ability to develop, produce and market our reserves may
              be limited by:
              - title problems,
              - weather conditions,
              - compliance with governmental requirements, and
              - mechanical difficulties or shortages or delays in the delivery
              of drilling rigs, work boats and other equipment.

         In the past, we have had difficulty securing drilling equipment in
certain of our core areas. We cannot assure you that the new wells we drill will
be productive or that we will recover all or any portion of our investment.
Drilling for crude oil and natural gas may be unprofitable. Dry wells and wells
that are productive but do not produce sufficient net revenues after drilling,
operating and other costs are unprofitable. In addition, our properties may be
susceptible to hydrocarbon draining from production by other operations on
adjacent properties.

         Our industry also experiences numerous operating risks. These operating
risks include the risk of fire, explosions, blow-outs, pipe failure, abnormally
pressured formations and environmental hazards. Environmental hazards include
oil spills, gas leaks, ruptures or discharges of toxic gases. If any of these
industry operating risks occur, we could have substantial losses. Substantial
losses also may result from injury or loss of life, severe damage to or
destruction of property, clean-up responsibilities, regulatory investigation and
penalties and suspension of operations. In accordance with industry practice, we
maintain insurance against some, but not all, of the risks described above. We
cannot assure you that our insurance will be adequate to cover losses or
liabilities. Also, we cannot predict the continued availability of insurance at
premium levels that justify its purchase.

We operate in a highly competitive industry which may adversely affect our
operations.

         We operate in a highly competitive environment. 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. We
compete with major and independent crude oil and natural gas companies for
properties and the equipment and labor required to develop and operate such
properties. Many of these competitors have financial and other resources
substantially greater than ours.

         The principal 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. We must compete for such resources with
both major crude oil and natural gas companies and independent operators.
Although we believe our current operating and financial resources are adequate
to preclude any significant disruption of our operations in the immediate future
we cannot assure you that such materials and resources will be available to us.


         We 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. Our principal competitors 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
ours. Smaller local distributors may enjoy a marketing advantage in their
immediate service areas.


         We compete against other companies in our natural gas processing
business both for supplies of natural gas and for customers to which we sell our
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.
                                       17
<PAGE>
         Our crude oil and natural gas operations are subject to various U.S.
federal, state and local and Canadian federal and provincial governmental
regulations that materially affect our operations. Matters regulated include
discharge permits for drilling operations, drilling and abandonment bonds,
reports concerning operations, the spacing of wells and unitization and pooling
of properties and taxation. At various times, regulatory agencies have imposed
price controls and limitations on production. In order to conserve supplies of
crude oil and natural gas, these agencies have restricted the rates of flow of
crude oil and natural gas wells below actual production capacity. Federal,
state, provincial and local laws regulate production, handling, storage,
transportation and disposal of crude oil and natural gas, by-products from crude
oil and natural gas and other substances and materials produced or used in
connection with crude oil and natural gas operations. To date, our expenditures
related to complying with these laws and for remediation of existing
environmental contamination have not been significant. We believe that we are in
substantial compliance with all applicable laws and regulations. However, the
requirements of such laws and regulations are frequently changed. We cannot
predict the ultimate cost of compliance with these requirements or their effect
on our operations.

         Abraxas common stock is currently traded on the OTC Bulletin Board
under the symbol "AXAS." Abraxas common stock was formerly listed on the NASDAQ
Stock Market under the symbol "AXAS," however, effective June 16, 1999, Abraxas
common stock was delisted from quotation on the NASDAQ Stock Market for failure
to satisfy NASDAQ's listing and maintenance standards. As of February 9, 2000,
Abraxas had 22,747,118 shares of common stock outstanding and had approximately
1,561 stockholders of record.

         The following table sets forth certain information as to the high and

                    UNAUDITED PRO FORMA FINANCIAL INFORMATION


         The following unaudited pro forma financial information is derived from
our historical financial statements and those of New Cache set forth elsewhere
in this prospectus and is adjusted to reflect the following:

         Our Unaudited Pro Forma Condensed Balance Sheet as of December 31,
1998, has been prepared assuming the offering of the first lien notes, the
acquisition of New Cache and the exchange offer were consummated on December 31,
1998. Our Unaudited Pro Forma Condensed Balance Sheet as of September 30, 1999,
has been prepared assuming the exchange offer was consummated on September 30,
1999. Our Unaudited Pro Forma Statements of Operations for the year ended
December 31, 1998 and for the nine month period ended September 30, 1998 have
been prepared assuming the offering of the first lien notes, the acquisition of
New Cache, the sale by Abraxas of its Wyoming Properties and the exchange offer
were consummated at the beginning of the reporting period. Our Unaudited Pro
Forma Statement of Operations for the nine month period ended September 30, 1999
has been prepared assuming the exchange offer was consummated at the beginning
of the reporting period. The historical revenues and expenses of New Cache and
the Wyoming Properties represent amounts recorded by or with respect to such
businesses or properties for the periods indicated.

         The historical financial statements of New Cache were prepared in
Canadian dollars in accordance with Canadian generally accepted accounting
principles. The New Cache historical statement of operations included in our
Unaudited Pro Forma Statement of Operations for the year ended December 31, 1998
represents the historical results of operations of New Cache for the twelve
months ended November 30, 1998, has been adjusted to present the results in
accordance with United States generally accepted accounting principles and has
been translated into U.S. dollars at the average exchange rate of $0.6792 to one
Canadian dollar. The balance sheet information of New Cache as of September 30,
1999, has been translated at the period-end exchange rate of $0.6523 to one
Canadian dollar. See "Business -- Primary Operating Areas -- Canada."

         The Unaudited Pro Forma Financial Information should be read in
conjunction with the notes thereto, our Consolidated Financial Statements and
the notes thereto and the historical financial statements and the notes thereto
of New Cache included elsewhere in this prospectus.

         Our Unaudited Pro Forma Financial Information is not indicative of our
financial position or results of operations which would actually have occurred
if the offering of the first lien notes, the acquisition of New Cache, the sale
of the Wyoming Properties and the exchange offer 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.

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


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


General


    We have incurred net losses for a number of years. Our revenues,
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 natural gas liquids we produce. Natural gas and crude oil prices
weakened somewhat during 1997 and continued to decrease during 1998. Crude oil
and natural gas prices have generally increased somewhat in 1999. The average
natural gas prices we realized were $1.59 per Mcf during the first nine months
of 1999 compared with:

    o   $1.54 per Mcf in 1998,
    o   $1.79 per Mcf in 1997, and

    o   $1.97 per Mcf in 1996.

    During the first nine months of 1999, crude oil prices averaged $13.98 per
Bbl compared with:

    o   $13.65 per Bbl in 1998,
    o   $18.63 per Bbl during 1997, and

    o   $20.85 per Bbl during 1996.


    Although we had net income during 1996, losses were incurred in 1997, 1998
and the first nine months of 1999, and there can be no assurance that operating
income and net earnings will be achieved in future periods. In addition, because
our proved reserves will decline as crude oil, natural gas and natural gas
liquids are produced, unless we are successful in acquiring properties
containing proved reserves or conduct successful exploration and development
activities, our reserves and production will decrease. Our ability to acquire or
find additional reserves in the near future will be severely diminished by our
lack of available funds for acquisition, exploration and development projects.
If crude oil and natural gas prices remain at depressed levels, or if our
production levels decrease, our revenues, cash flow from operations and
financial condition will be materially adversely affected.


Results of Operations


    The factors which most significantly affect our results of operations are:


    (1) the sales prices of crude oil, natural gas liquids and natural gas,

    (2) the level of total sales volumes of crude oil, natural gas liquids and
        natural gas,


    (3) the level of borrowings and interest rates thereon, and


    (4) the level and success of exploration and development activity.


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

increased from $41.4 million in the nine months ended September 30, 1998 to
$43.9 million for the same period in 1999. Increased production of crude oil and
natural gas contributed $2.6 million in additional revenue, while higher crude
oil and natural gas prices added revenue of $1.4 million. Lower production of
natural gas liquids had a negative impact of $5.2 million offset by $3.6 million
from higher prices.


    Crude oil production increased from 564.9 MBbls for the first nine months of
1998 to 608.6 MBbls for the same period of 1999. Production from the New Cache
properties (acquired in January 1999) contributed 228.1 MBbls in 1999. This
production was offset by declines in the production from our existing properties
and from the divestiture of our properties in Wyoming which were sold in
November 1998. The Wyoming Properties contributed 74.6 MBbls of crude oil in the
nine months ended September 30, 1998. The decline in the production from
existing properties was as a result of the de-emphasis of our crude oil
exploration and development program in 1999 due to depressed crude oil prices
during the first part of 1999. Crude oil prices improved in the third quarter.
The average price received for crude oil for the first nine months of 1999 was
$13.98 per Bbl compared to $13.75 per Bbl for the same period of 1998.

    Natural gas production increased by 1,281 MMcf for the first nine months of
1999 to 20,155 MMcf from 18,874 MMcf for the same period of 1998. The
acquisition of New Cache contributed 5,200 MMcf during the nine months ended
September 30, 1999 which offset the loss of production from the Wyoming
Properties, which were sold in the fourth quarter of 1998. For the nine months
ended September 30, 1998 the Wyoming Properties contributed 4,599 MMcf. The
increase in natural gas volumes contributed $2.0 in additional revenue.
Increased natural gas prices received during the nine months ended September 30,
1999 contributed an additional $1.3 million to revenue for the period. The
average natural gas price received during the first none months of 1999 was
$1.59 per Mcf compared to $1.52 per Mcf for the same period of 1998.

    Revenue from natural gas liquids declined $1.6 million from $4.9 million for
the nine months ended September 30, 1998 to $3.4 million for the same period of
1999. Reduced production of natural gas liquids had a negative impact of $5.2
million on revenue for the nine months ended September 30, 1999 which was offset
by $3.6 million of increased revenue due to higher prices for the period.
Average natural gas liquids sales prices for the six months ended September 30,
1999 were $11.96 per Bbl compared to $6.90 for the same period of 1998. Natural
gas liquid production declined to 281.5 MBbls for the nine months ended
September 30, 1999 from 715.4 MBbls for the same period of 1998. The decline in

                                       32
<PAGE>
natural gas liquids volumes was due to the divestiture of the Wyoming Properties
in the fourth quarter of 1998 and our decision to shut down the East White Point
and Portilla plants in South Texas. The Wyoming Properties contributed 385.5
MBbls of natural gas liquids during the first nine months of 1998 which was
partially offset by 57.2 MBbls from the New Cache properties acquired in January
1999. We shut down our East White Point processing plant during the fourth
quarter of 1998 and shut down our Portilla Plant in January 1999. The East White
Point plant produced 40.4 MBbls of natural gas liquids during the first nine
months of 1998 and the Portilla Plant contributed 38.0 MBbls of natural gas
liquids during the first nine months of 1998 compared to 2.1 MBbls in 1999. We
began processing the East White Point gas through a third party plant in April
1999. Total East White Point production through this facility was 37.7 MBbls
during the period ended September 30, 1999. We also elected not to process our
West Texas gas during the first quarter of 1999 due to the depressed prices of
natural gas liquids. Processing of the West Texas gas resumed in April 1999
contributing 41.7 MBbls during the period ended September 30, 1999.

    Lease Operating Expenses. Lease Operating Expense ("LOE") and natural gas
processing expenses were $14.0 million for the nine months ended September 30,
1999 compared to $13.4 million for the same period in 1998. The increase of $0.6
million was due to an increase in the number of wells we owned as of September
30, 1998 compared to the same period of the prior year. LOE on a per Mcfe basis
increased to $0.55 per Mcfe for the nine months ended September 30, 1999 from
$0.50 for the same period of 1998. The increase per Mcfe was due to a general
increase in the cost of services from 1998 to 1999 as well as from the
divestiture of the Wyoming Properties which was a low cost operating area with
LOE of $0.16 per Mcfe.

    G&A Expenses. General and Administrative ("G&A") expenses increased from
$4.0 million for the nine months ended September 30, 1998 to $4.2 million for
the same period of 1999. The increase was primarily due to the hiring of
additional staff to manage and develop our properties including the addition of
several staff members associated with the New Cache acquisition. G&A expense on
a per Mcfe basis increased to $0.16 per Mcfe from $0.15 for the same period of
1998.

    Depreciation, Depletion and Amortization Expenses. Depreciation, Depletion
and Amortization ("DD&A") expense decreased to $25.8 million for the nine months
ended September 30, 1999, from $26.0 million for the same period of 1998. DD&A
expense on a per Mcfe basis was $1.01 per Mcfe for the nine months ended
September 30, 1999 compared to $0.98 per Mcfe for the nine months ended June 30,
1998. The increase on a per Mcfe basis was due to higher finding cost during
1999, including the acquisition of New Cache, in our Canadian operations and the
loss of reserves resulting from low commodity prices that forced some of our oil
properties to their economic limits much sooner. The increases were partially
offset by lower DD&A per Mcfe from the U.S. operations as a result of the
ceiling test write down of the U.S. full cost pool as of December 31, 1998.

    Interest Expense. Interest increased to $28.4 million for the nine months
ended September 30, 1999 from $22.8 million for the nine months ended September
30, 1998. The increase was due to our increased levels of borrowings during the
first nine months of 1999. Long-term debt increased from $299.7 million at
December 31, 1998 to $346.2 million at September 30, 1999, as a result of our
issuing $63.5 million of the first lien notes.

    General. Our revenues, 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 natural gas liquids we produce. The
prices of natural gas, crude oil and natural gas liquids we received improved
during the first nine months of 1999. The average natural gas price we realized
increased to $1.59 per Mcf during the first nine months of 1999 compared with
$1.52 per MCF during the same period of 1998. Crude oil prices increased from
$13.75 per Bbl during the nine months of September 1998, to $13.98 per Bbl for
the same period of 1999. Natural gas liquids prices increased to $11.96 per Bbl
compared to $6.90 per Bbl in 1998. The prices of crude oil and natural gas have
strengthened in the third quarter and continued to strengthen in the fourth
quarter. In addition, our proved reserves will decline as crude oil, natural gas
and natural gas liquids are produced unless we are successful in acquiring
properties containing proved reserves or conduct successful exploration and
development activities. In the event crude oil, natural gas and natural gas
liquid prices return to depressed levels or if our production levels decrease,
our revenues, cash flow from operations and profitability will be materially
adversely affected.

Comparison of Year Ended December 31, 1998 to Year Ended December 31, 1997

    Operating Revenue. During the year ended December 31, 1998, operating
revenue from crude oil, natural gas and natural gas liquids sales, and natural
gas processing revenues decreased by $12.0 million from $69.4 million in 1997 to
$57.4 million in 1998, of which $11.8 million was attributable to the Wyoming
Properties. This decrease was primarily attributable to a decline in commodity
prices.


    Production volumes increased 5.8% from 32,622 MMcfe in 1997 to 34,505 MMcfe
for the year ended December 1998, of which 8,609 MMcfe were attributable to the
Wyoming Properties. Crude oil and natural gas liquids sales volumes decreased by
17.2% from 1,930 MBbls in 1997 to 1,596 MBbls during 1998, and natural gas sales
volumes increased by 18.4% from 21.1 Bcf in 1997 to 38.4 Bcf in 1998. The
increase in natural gas sales volumes was attributable to increased production
attributable to our ongoing development program on existing and acquired
properties. Crude oil sales volumes decreased 22.2% to 729 MBbls during 1998
from 937 MBbls in 1997. This decrease was due primarily to our decreased
emphasis on crude oil development projects during 1998 in response to the
continuing decline in crude oil prices.

    Natural gas liquids sales volumes decreased 12.6% to 867 MBbls in 1998 from
992 MBbls in 1997. Approximately 66 MBbls of the decline in natural gas liquids
was attributable to the loss of production from the Wyoming Properties. In the
ten and one-half months that we owned the Wyoming Properties during 1998, they
contributed 89 MBbls of crude oil, 454 MBbls of natural gas liquids and 5.4 Bcf
of natural gas production. Average sales prices in 1998 were:

    o   $13.65 per Bbl of crude oil,
    o   $6.81 per Bbl of natural gas liquids, and
    o   $1.54 per Mcf of natural gas.

    Average sales prices in 1997 were:

    o   $18.63 per Bbl of crude oil,
    o   $10.75 per Bbl of natural gas liquids, and
    o   $1.79 per Mcf of natural gas.

We also had natural gas processing  revenues of $3.1 million in 1998 as compared
to $3.6 million in 1997.

    Lease Operating Expense. LOE and natural gas processing costs increased by
$2.0 million from $16.1 million for the year ended December 31, 1997 to $18.1
million for the same period of 1998, of which $2.0 million was attributable to
the Wyoming Properties. The increase was due primarily to the greater number of
wells we owned for the year ended December 31, 1998 compared to the year ended
December 31, 1997. Our LOE on a per Mcfe basis for 1998 was $0.49 per Mcfe as
compared to $0.46 per Mcfe in 1997. Natural gas processing costs remained
constant at $1.2 million in 1998 as compared to $1.2 million in 1997.

    G&A Expense. G&A expense increased from $4.2 million for the year ended
December 31, 1997 to $5.3 million for the year ended December 31, 1998, as a
result of our hiring of additional staff. The sale of the Wyoming Properties has
not had a material effect on G&A expense. Our G&A expense on a per Mcfe basis
was $0.16 per Mcfe in 1998 compared to $0.13 per Mcfe for 1997.

    DD&A Expense. Due to the increase in sales volumes of crude oil and natural
gas, DD&A expense increased by $600,000 from $30.6 million for the year ended
December 31, 1997 to $31.2 million for the year ended December 31, 1998, of
which $3.4 million was attributable to the Wyoming Properties. Our DD&A expense
on a per Mcfe basis for 1998 was $0.90 per Mcfe as compared to $0.94 per Mcfe in
1997.

    Interest Expense and Preferred Dividends. Interest expense and preferred
dividends increased by $6.2 million from $24.6 million to $30.8 million for the
year end December 31, 1998 compared to 1997. This increase was attributable to
our increased borrowings during 1998. In January 1998, Abraxas and Canadian


                                       34
<PAGE>

Abraxas issued $60.0 million in principal amount of 11.5% Senior Notes due 2004,
Series C ("Series C Notes"), and in June 1998, Abraxas and Canadian Abraxas
exchanged all of their outstanding Series C Notes and their 11.5% Senior Notes
due 2004, Series B in the original principal amount of $215.0 million ("Series B
Notes") for $275.0 million of the old notes

    During 1998, we also made additional borrowings under our revolving credit
facility (the "Credit Facility"). Long-term debt increased from $248.6 million
at December 31, 1997 to $299.7 million at December 31, 1998. During 1998, we
paid no preferred dividends as compared to $183,000 in 1997. Preferred dividends
were eliminated on July 1, 1997 as the result of the conversion of all
outstanding preferred stock into Abraxas common stock.

    Ceiling Limitation Writedown. We record the carrying value of our crude oil
and natural gas properties using the full cost method of accounting for oil and
gas properties. Under this method, we capitalize the cost to acquire, explore
for and develop oil and gas properties. Under the full cost accounting rules,
the net capitalized cost of crude oil and natural gas properties less related
deferred taxes, are limited by country, to the lower of the unamortized cost or
the cost ceiling, defined as the sum of the present value of estimated
unescalated future net revenues from proved reserves, discounted at 10%, plus
the cost of properties not being amortized, if any, plus the lower of cost or
estimated fair value of unproved properties included in the costs being
amortized, if any, less related income taxes. If the net capitalized cost of
crude oil and natural gas properties exceeds the ceiling limit, we are subject
to a ceiling limitation writedown to the extent of such excess. A ceiling
limitation writedown is a charge to earnings which does not impact cash flow
from operating activities. However, such writedowns do impact the amount of our
stockholders' equity.

    The risk that we will be required to writedown the carrying value of our
crude oil and natural gas assets increases when crude oil and natural gas prices
are depressed or volatile. In addition, writedowns may occur if we have
substantial downward revisions in our estimated proved reserves or if purchasers
or governmental action cause an abrogation of, or if we voluntarily cancel,
long-term contracts for our natural gas. For the year ended December 31, 1998,
we recorded a writedown of $61.2 million related to our United States
properties. No assurance can be given that we will not experience additional
writedowns in the future. Should commodity prices continue to decline, a further
writedown of the carrying value of our crude oil and natural gas properties may
be required. See Note 16 of Notes to Consolidated Financial Statements.


Comparison of Year Ended December 31, 1997 to Year Ended December 31, 1996

    Operating Revenue. During the year ended December 31, 1997, operating
revenue from crude oil, natural gas and natural gas liquids sales, and natural
gas processing revenues increased by $43.1 million from $26.3 million in 1996 to
$69.4 million in 1997. This increase was primarily attributable to increased
volumes which were partially offset by a decline in commodity prices.


    Production volume increased from 10,698 MMcfe to 32,624 MMcfe for the year
ended December 1997. Crude oil and natural gas liquids sales volumes increased
by 166% to 11,573 MMcfe during 1997 compared to 4,350 MMcfe in 1996, and natural
gas sales volumes increased by 231% to 21.1 Bcf in 1997 compared to 6.3 Bcf in
1996. The increases in volumes were attributable to a full year of production
from property acquisitions completed during the fourth quarter of 1996 as well
as increased production attributable to our ongoing development program on
existing and acquired properties. Acquisitions and the subsequent development of
the acquired properties contributed 1,182 MBbls of oil and natural gas liquids
and 15.9 Bcf of natural gas. Development of existing properties contributed 747
MBbls of oil and natural gas liquids and 5.2 Bcf of natural gas during 1997.
Average sales prices in 1997 were:

    o   $18.63 per Bbl of crude oil,
    o   $10.75 per Bbl of natural gas liquid, and
    o   $1.79 per Mcf of natural gas.

                                       35
<PAGE>
    Average sales prices in 1996 were:

    o   $20.85 per Bbl of crude oil,
    o   $14.55 per Bbl of natural gas liquids, and
    o   $1.97 per Mcf of natural gas in 1996.

    We also had gas processing revenue of $3.6 million in 1997 as a result of
the acquisition of CGGS Canadian Gas Gathering Systems Inc. ("CGGS") in November
1996. Prior to the acquisition, we were not engaged in third party gas
processing.

    Lease Operating Expense. LOE and natural gas processing costs increased by
$10.0 million from $6.1 million for the year ended December 31, 1996 to $16.1
million for the same period of 1997. LOE increased by $9.0 million to $14.9
million primarily due to the greater number of wells we owned for the year ended
December 31, 1997 compared to the year ended December 31, 1996. Our LOE on a per
Mcfe basis for 1997 was $0.46 per Mcfe as compared to $0.55 per Mcfe in 1996.
Natural gas processing costs increased to $1.3 million in 1997 as compared to
$262,000 in 1996. The increase in gas processing expense was due to the
acquisition of CGGS in November 1996. Prior to the acquisition, we were not
engaged in third party gas processing

    G&A Expense. G&A expense increased by $2.3 million from $1.9 million for the
year ended December 31, 1996 to $4.2 million for the year ended December 31,
1997, as a result of our hiring of additional staff, including an increase in
personnel to manage and develop properties acquired in the fourth quarter of
1996. Our G&A expense on a per Mcfe basis was $0.13 per Mcfe in 1997 compared to
$0.18 per Mcfe for 1996.

    DD&A Expense. Due to the increase in sales volumes of crude oil and natural
gas, DD&A expense increased by $21.0 million from $9.6 million for the year
ended December 31, 1996 to $30.6 million for the year ended December 31, 1997.
Our DD&A expense on a per Mcfe basis for 1997 was $0.94 per Mcfe as compared to
$0.90 per Mcfe in 1996.

    Interest Expense and Preferred Dividends. Interest expense and preferred
dividends increased by $18.1 million from $6.4 million to $24.5 million for the
year end December 31, 1997, compared to 1996. This increase was attributable to
our increased borrowings to finance the acquisitions consummated during 1996. In
November 1996, we issued $215 million in principal amount of the Series B Notes.
During 1997, We made additional borrowings under the Credit Facility. Long-term
debt increased from $215.0 million at December 31, 1996 to $248.6 million at
December 31, 1997. During 1997, we paid $183,000 in preferred dividends as
compared to $366,000 in 1996. Preferred dividends were eliminated on July 1,
1997 as the result of the conversion of all outstanding preferred stock into
Abraxas common stock.

    Ceiling Limitation Writedown. For the year ended December 31, 1997, we
recorded a writedown of $4.6 million, $3.0 million after tax, related to our
Canadian properties.


Liquidity and Capital Resources

    General. Capital expenditures excluding property divestitures during the
nine months ended September 30, 1999 were $115.3 million compared to $41.7
million during the same period of 1998. The table below sets forth the
components of these capital expenditures on a historical basis for the six
months ended September 30, 1999 and 1998.

    At September 30, 1999, we had current assets of $32.5 million and current
liabilities of $34.3 million resulting in a working capital deficit of $1.8
million. This compares to working capital of $50.7 million at December 31, 1998
and a working capital deficit of $9.1 million at September 30, 1998. The
material components of our current liabilities at September 30, 1999 include
trade accounts payable of $8.5 million, revenues due third parties of $10.5
million and accrued interest of $13.6 million.

    Operating activities during the nine months ended September 30, 1999
provided us $9.3 million in cash compared to $6.1 million in the same period in
1998. Net income plus non-cash expense items during 1999 and net changes in
operating assets and liabilities accounted for most of these funds.


    Investing activities required $100.4 million net during the first nine
months of 1999, $92.6 million of which was utilized for the acquisition of oil
and gas properties, $21.0 million of which was utilized for the development of
crude oil and natural gas properties and other facilities, and $1.7 million of
which was utilized for facilities and other. Divestitures of oil and gas
properties provided $14.8 million. This compares to $41.7 million required
during the same period of 1998, $35.5 million of which was utilized for the
development of crude oil and natural gas properties and other facilities, and
$2.4 million for the acquisition of oil and gas properties.

    Financing activities provided $43.9 million for the first nine months of
1999 compared to providing $39.5 million for the same period of 1998. Financing
activities include the proceeds of $63.5 million from the issuance of the first
lien notes in March 1999 and borrowings under the Credit Facility of $19.5
million, which were offset by the repayment of the Credit Facility in the amount
of $35.2 million in March 1999.


    Our budget for capital expenditures for 2000 other than acquisition
expenditures is approximately $49.0 million. Such expenditures will be made
primarily for the development of existing properties. Additional capital
expenditures may be made for acquisitions of producing properties if such
opportunities arise, but we currently have no agreements, arrangements or
undertakings regarding any material acquisitions. We have no material long-term
capital commitments and are consequently able to adjust the level of our
expenditures as circumstances dictate. Additionally, the level of capital
expenditures will vary during future periods depending on market conditions and
other related economic factors. Should commodity prices remain at depressed
levels or decline further, reductions in the capital expenditure budget may be
required.

    Current Liquidity Needs. We have historically funded our operations and
acquisitions primarily through our cash flow from operations and borrowings
under a credit facility and other credit sources. In March 1999, we issued $63.5
million principal amount of the first lien notes and repaid all amounts
outstanding under the credit facility and approximately $10.0 million of debt
assumed in connection with the acquisition of New Cache. Due to severely
depressed prices for crude oil and natural gas during the early part of 1999,
our cash flow from operations has been substantially reduced.

    In October 1999, we sold a dollar denominated production payment for $4.0
million relating to existing natural gas wells in the Edwards Trend in South
Texas to a unit of Southern Energy, Inc. In January 2000, Abraxas sold an
additional production payment for $2.0 million relating to additional natural
gas wells in the Edwards Trend to Southern. We have the ability to sell up to
$50 million to Southern for drilling opportunities in the Edwards Trend.

                                       37
<PAGE>
    We will have four principal sources of liquidity going forward: (i) cash on
hand, (ii) cash flow from operations, (iii) the production payment with Southern
and (iv) proceeds from the sale of non-core assets. While the availability of
capital resources cannot be predicted with certainty and is dependent upon a
number of factors including factors outside of management's control, management
believes that the net cash flow from operations plus cash on hand, cash
available under the production payment and the proceeds from the sale of certain
non-core properties will be adequate to fund operations and planned capital
expenditures.

    Our ability to obtain additional financing will be substantially limited
under the terms of the old notes, the first lien notes and the second lien
notes. Substantially all of our crude oil and natural gas properties and natural
gas processing facilities are subject to a first lien or charge for the benefit
of the holders of the first lien notes and a second lien or charge for the
benefit of the holders of the second lien notes. Thus, we will be required to
rely on our cash flow from operations to fund our operations and service our
debt. We may also choose to issue equity securities or sell additional assets to
fund our operations, although the indentures governing the old notes, first lien
notes and second lien notes substantially limit our use of the proceeds of any
such asset sales. Due to our diminished cash flow from operations and the
resulting depressed prices for our common stock, there can be no assurance that
we would be able to obtain equity financing on terms satisfactory to us.


Long-Term Indebtedness

    Old Notes. On November 14, 1996, the Issuers consummated the offering of
$215.0 million of their 11.5% Senior Notes due 2004, Series A, which were
exchanged for the Series B Notes in February 1997. On January 27, 1998, the
Issuers completed the sale of $60.0 million of the Series C Notes. The Series B
Notes and the Series C Notes were subsequently exchanged for $275.0 million in
principal amount of the old notes in June 1998.

    Interest on the old notes is payable semi-annually in arrears on May 1 and
November 1 of each year at the rate of 11.5% per annum. The old notes are
redeemable, in whole or in part, at the option of the Issuers, on or after
November 1, 2000, at the redemption prices set forth below, plus accrued and
unpaid interest to the date of redemption, if redeemed during the 12-month
period commencing on November 1 of the years set forth below:


           Year                                             Percentage

           2000...........................................   105.750%
           2001...........................................   102.875%
           2002 and thereafter............................   100.000%


    The old notes are joint and several obligations of the Issuers and rank pari
passu in right of payment to all existing and future unsubordinated indebtedness
of the Issuers. The old notes rank senior in right of payment to all future
subordinated indebtedness of the Issuers. The old notes are, however,
effectively subordinated to the first lien notes to the extent of the value of
the collateral securing the first lien notes and the second lien notes to the
extent of the value of the collateral securing the second lien notes. The old
notes are unconditionally guaranteed, on a senior basis by Sandia. The guarantee
is a general unsecured obligation of Sandia and ranks pari passu in right of
payment to all unsubordinated indebtedness of Sandia and senior in right of
payment to all subordinated indebtedness of Sandia. The guarantee is effectively
subordinated to the first lien notes and the second lien notes to the extent of
the value of the Collateral.

    Upon a Change of Control (as defined in the old notes indenture), each
holder of the old notes will have the right to require the Issuers to repurchase
all or a portion of such holder's old 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 old 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.

    First Lien Notes. In March 1999, Abraxas consummated the sale of $63.5
million of the first lien notes. Interest on the first lien notes is payable
semi-annually in arrears on March 15 and September 15, commencing September 15,
1999. The first lien notes are redeemable, in whole or in part, at the option of
Abraxas on or after March 15, 2001, at the redemption prices set forth below,
plus accrued and unpaid interest to the date of redemption, if redeemed during
the 12-month period commencing on March 15 of the years set forth below:


           Year                                             Percentage

           2001............................................   103.000%
           2002 and thereafter.............................   100.000%

    At any time, or from time to time, prior to March 15, 2001, Abraxas may, at
its option, use all or a portion of the net cash proceeds of one or more equity
offerings to redeem up to 35% of the aggregate original principal amount of the
fist lien notes at a redemption price equal to 112.875% of the aggregate
principal amount of the first lien notes be redeemed, plus accrued and unpaid
interest.

    The first lien notes are senior indebtedness of Abraxas secured by a first
lien on substantially all of the crude oil and natural gas properties of Abraxas
and the shares of Grey Wolf owned by Abraxas. The first lien notes are
unconditionally guaranteed on a senior basis, jointly and severally, by Canadian
Abraxas, Sandia and Wamsutter. The guarantees are secured by substantially all
of the crude oil and natural gas properties of the guarantors and the shares of
Grey Wolf owned by Canadian Abraxas.

    Upon a Change of Control, each holder of the first lien notes will have the
right to require Abraxas to repurchase such holder's first lien 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, Abraxas will be
obligated to offer to repurchase the first lien 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.

    The first lien notes indenture contains certain covenants that limit the
ability of Abraxas and certain of its subsidiaries, including the guarantors of
the first lien notes (the "Restricted Subsidiaries") 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, 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 Abraxas.

    The first lien notes indenture provides, among other things, that Abraxas
may not, and may not cause or permit the Restricted Subsidiaries, to, directly
or indirectly, create or otherwise cause to permit to exist or become effective
any encumbrance or restriction on the ability of such subsidiary to pay
dividends or make distributions on or in respect of its capital stock, make
loans or advances or pay debts owed to Abraxas or any other Restricted
Subsidiary, guarantee any indebtedness of Abraxas or any other Restricted
Subsidiary or transfer any of its assets to Abraxas or any other Restricted
Subsidiary except for such encumbrances or restrictions existing under or by
reason of:

         (1) applicable law;

         (2) the first lien notes indenture;

         (3) customary non-assignment provisions of any contract or any lease
governing leasehold interest of such subsidiaries;

         (4) any instrument governing indebtedness assumed by us in an
acquisition, which encumbrance or restriction is not applicable to such
Restricted Subsidiary or the properties or assets of such subsidiary other than
the entity or the properties or assets of the entity so acquired;

                                       39
<PAGE>
         (5) agreements existing on the Issue Date (as defined in the first lien
notes indenture) to the extent and in the manner such agreements were in effect
on the Issue Date;

         (6) customary restrictions with respect to subsidiaries of Abraxas
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 first lien notes indenture or any Security
Documents (as defined in the first lien notes indenture) solely in respect of
the assets or capital stock to be sold or disposed of;

         (7) any instrument  governing certain liens permitted by the first lien
notes indenture,  to the extent and only to the extent such instrument restricts
the transfer or other disposition of assets subject to such lien; or

         (8) an agreement governing indebtedness incurred to refinance the
indebtedness issued, assumed or incurred pursuant to an agreement referred to in
clause (ii), (iv) or (v) 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 of the first lien notes in any
material respect as determined by the Board of Directors of Abraxas in their
reasonable and good faith judgment that the provisions relating to such
encumbrance or restriction contained in the applicable agreement referred to in
such clause (ii), (iv) or (v) and do not extend to or cover any new or
additional property or assets and, with respect to newly created liens, (A) such
liens are expressly junior to the liens securing the first lien notes, (B) the
refinancing results in an improvement on a pro forma basis in Abraxas'
Consolidated EBITDA Coverage Ratio (as defined in the first lien notes
indenture) and (C) the instruments creating such liens expressly subject the
foreclosure rights of the holders of the refinanced indebtedness to a
stand-still of not less than 179 days.


         Second Lien Notes. In December 1999, the Issuers consummated an
exchange offer whereby $188,778,000 of the second lien notes were exchanged for
$269,699,000 of the old notes. An additional $5,000,000 of the second lien notes
were issued to Houlihan and Jefferies in payment of fees and expenses. You
should read the discussion under the heading "Summary of the Second Lien Notes"
for more information regarding the second lien notes.


         Hedging Activities. Our results of operations are significantly
affected by fluctuations in commodity prices and we seek to reduce our exposure
to price volatility by hedging our production through swaps, options and other
commodity derivative instruments.

         In November 1996, we assumed hedge agreements extending through October
2001 with a counterparty involving various quantities and fixed prices. These
hedge agreements provided that we make payments to the counterparty to the
extent the market prices, determined based on the price for crude oil on the
NYMEX and the Inside FERC, Tennessee Gas Pipeline Co. Texas (Zone O) price for
natural gas exceeded certain fixed prices and for the counterparty to make
payments to us to the extent the market prices were less than such fixed prices.
We accounted for the related gains or losses (a gain of $204,600 during the
first quarter of 1999) in crude oil and natural gas revenue in the period of the
hedged production. We terminated these hedge agreements in January 1999 and were
paid $750,000 by the counterparty for such termination. This amount is included
in other income in the accompanying financial statements.

         In March 1998, we entered into a costless collar hedge agreement with
Enron Capital and Trade Resources Corp. for 2,000 Bbls of crude oil per day with
a floor price of $14.00 per Bbl and a ceiling price of $22.30 per Bbl for crude
oil on the NYMEX. The agreement was effective April 1, 1998 and extended through
March 31, 1999. Under the terms of the agreement we were paid when the average
monthly price for crude oil on the NYMEX is below the floor price and will pay
the counterparty when the average monthly price exceeds the ceiling price.
During the nine months ended September 30, 1999 we realized a gain of $204,000
on this agreement, which is accounted for in crude oil and natural gas revenue.
We have also entered into a hedge agreement with Barrett Resources Corporation


                                       40
<PAGE>

("Barrett") for the period November 1999 through October 2000. This agreement is
for 1,000 Bbls per day with us being paid $20.30 and 1,000 barrels per day with
a floor price of $18.00 per barrel and a ceiling of $22.00 per Bbl.
Additionally, Barrett has a call on either 1,000 Bbls of crude oil or 20,000
MMBtu of natural gas per day at Barrett's option at fixed prices through October
31, 2002.

         As of February 1, 2000, we had 22.5 MMBtupd hedged through to October
31, 2000. Of the 22.5 MMBtupd, 2.5 MMBtupd is hedged at an average NYMEX price
less $0.83 (approximately $1.75 per MMBtu as of February 2000) and 20.0 MMBtupd
with a ceiling of $2.39 and a floor of $2.07 based on an AECO index. Both of
these hedges are with Barrett Resources. In connection with the 20.0 MMBtupd
Barrett hedge, we realized a loss of $1.8 million for the nine months ended
September 30, 1999, which is accounted for in crude oil and natural gas revenue.

         Net Operating Loss Carryforwards. At December 31, 1998, we had, subject
to the limitations discussed below, $59.2 million of net operating loss
carryforwards for U.S. tax purposes, of which approximately $55.0 million are
available for utilization without limitation. These loss carryforwards will
expire from 1999 through 2019 if not utilized. At December 31, 1998, we had
approximately $11.9 million of net operating loss carryforwards for Canadian tax
purposes which expire in varying amounts in 2002-2005. 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 $4.9 million in net
operating loss carryforwards generated prior to December 31, 1991 will be
limited to approximately $235,000 per year. As a result of the issuance of
additional shares of common stock for acquisitions and sales of stock, an
additional ownership change under Section 382 occurred in October 1993.
Accordingly, it is expected that the use of all U.S. net operating loss
carryforwards generated through October 1993, or $8.9 million, will be limited
to approximately $1 million per year subject to the lower limitations described
above. Of the $8.9 million net operating loss carryforwards, it is anticipated
that the maximum net operating loss that may be utilized before it expires is
$6.1 million. Future changes in ownership may further limit the use of our
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, we have established
a valuation allowance of $5.9 million and $32.8 million for deferred tax assets
at December 31, 1997 and 1998, respectively.

         Based upon the current level of operations, we believe that cash on
hand, cash flow from operations, proceeds from the Production Payment, reduced
interest expense as a result of the exchange offer and proceeds from the sale of
non-core assets will be adequate to meet our anticipated requirements for
working capital, capital expenditures and scheduled interest payments through
2000. Depressed prices for natural gas, crude oil or natural gas liquids will
have a material adverse effect on our cash flow from operations and anticipated
levels of working capital, and could force us to revise our planned capital
expenditures.


Year 2000


         We have assessed the impact of the Year 2000 issue on our operations,
including the development and implementation of project plans and cost estimates
required to make our information system infrastructure, information systems and
embedded technology Year 2000 compliant. Substantially all of our computer
hardware and software has been obtained from third party vendors. We have been
advised by the vendors of each of our most material hardware and software
systems that such systems are Year 2000 compliant. We have performed independent
testing of critical applications to verify the accuracy of such assertions. We
believe that all of our information system infrastructure, information systems
and embedded technology are compliant and Year 2000 ready.

                                       41
<PAGE>

         In the area of third party suppliers and customers, we have monitored
and assessed the readiness of such third parties. We monitor third party
readiness based on correspondence received from our major vendors and suppliers,
review of Year 2000 disclosure in documents filed with the SEC and verbal
communications. We have not identified any material problems associated with the
Year 2000 readiness efforts of our major suppliers and customers and, other than
correspondence, documents filed with the SEC and verbal communications, we have
not received any assurances that such customers and suppliers will be Year 2000
compliant.

         Our current emphasis in this area is focused on contingency planning in
recognition of the uncertainties inherent in evaluating third party readiness.
Our contingency planning involves all areas of readiness. The process includes
identifying critical dependencies and developing proactive prevention plans.

         To date, we have spent approximately $120,000 in replacing computer
hardware and software we did not believe to be Year 2000 compliant, some of
which we had already anticipated replacing for other reasons. Such expenditures
have been funded out of our operational cash flows. Based on existing
information, we do not anticipate having to spend any further material amounts
to become Year 2000 compliant and that any such required amounts will not have a
material effect on our financial position, cash flows or results of operations .

         There is a risk of Year 2000 related failures. These failures could
result in an interruption in or a failure of certain business activities or
functions. Such failures could materially and adversely affect our results of
operations, liquidity or financial condition. Due to the uncertainty surrounding
the Year 2000 problem, including the uncertainty of the Year 2000 readiness of
our customers and suppliers, we are unable at this time to determine the true
impact of the Year 2000 problem on us. The principal areas of risk are thought
to be oil and gas production control systems, other imbedded operations control
systems and third party Year 2000 readiness. There can be no assurance, however,
that there will not be delay in, or increased costs associated with the
implementation of measures to address the Year 2000 issue or that such measures
will prove effective in resolving all Year 2000 related issues. Furthermore,
there can be no assurance that critical contractors, customers or other parties
with which we do business will not experience failures.

         We believe that the "most reasonably likely worst case" scenarios are
as follows: (i) unanticipated Year 2000 induced failures in information systems
could cause a reliance on manual contingency procedures and significantly reduce
efficiencies in the performance of certain normal business activities; (ii)
unanticipated failures in embedded operations process control systems due to
Year 2000 causes could result in temporarily suspending operations at certain
operating facilities with consequent loss of revenue; and (iii) slowdowns or
disruptions in the third party supply chain due to Year 2000 performance of
certain normal business activities.

         As of February 10, 2000, we have not and, to our knowledge, none of our
third-party suppliers or customers have experienced any Year 2000 related
failures. However, there is a continuing risk of such failures for both us and
our third-party suppliers and customers.


Quantitative and Qualitative Disclosures about Market Risk; Commodity Price Risk

Commodity Price Risk


         Our exposure to market risks rest primarily with the volatile nature of
crude oil, natural gas and natural gas liquids prices. We manage crude oil and
natural gas prices through the periodic use of commodity price hedging
agreements. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources". Assuming the production
levels we attained during the nine months ended September 30, 1999, a 5% decline
in crude oil, natural gas and natural gas liquids prices would have reduced our
operating revenue, cash flow and net income (loss) by approximately $2.2 million
for the nine months ended September 30, 1999.



                                       42
<PAGE>
Interest rate risk


         At September 30, 1999, substantially all of our long-term debt is at
fixed interest rates and not subject to fluctuations in market rates.


Foreign currency


         Our Canadian operations are measured in the local currency of Canada.
As a result , our financial results could be affected by changes in foreign
currency exchange rates or weak economic conditions in the foreign markets.
Canadian operations reported a pre tax loss of $6.4 million for the nine months
ended September 30, 1999. It is estimated that a 5% change in the value of the
U.S. dollar to the Canadian dollar would have changed our net income by
approximately $0.13 million. We do not maintain any derivative instruments to
mitigate the exposure to translation risk. However, this does not preclude the
adoption of specific hedging strategies in the future.

                                    BUSINESS

General

    We are an independent energy company engaged primarily in the acquisition,
exploration, exploitation and production of crude oil and natural gas. Since
January 1, 1991, our principal means of growth has been through the acquisition
and subsequent development and exploitation of producing properties and related
assets.


    Abraxas was founded in 1977 by Robert L. G. Watson, our Chairman of the
Board, President and Chief Executive Officer. Our principal offices are located
at 500 North Loop 1604 East, Suite 100, San Antonio, Texas 78232 and the
telephone number is (210) 490-4788. Canadian Abraxas was formed in 1996.
Canadian Abraxas' principal offices are located at 300 5th Avenue SW, #1200,
Calgary, Alberta, Canada T2P 3C4 and the telephone number is (403) 262-1949.


1999 Developments

    On December 31, 1999, New Cache, which had been owned by Abraxas and
Canadian Abraxas, was amalgamated or merged with Canadian Abraxas. New Cache
originally guaranteed the second lien notes; however, as a result of the
amalgamation, New Cache is no longer a guarantor of the second lien notes.

    In December 1999, Abraxas and Canadian Abraxas completed an exchange offer
whereby they exchanged the second lien notes, Abraxas common stock, and
contingent value rights for approximately 98.43% of their outstanding old notes.
The second lien notes are senior obligations of Abraxas and Canadian Abraxas and
are jointly and severally guaranteed by Sandia and Wamsutter. The second lien
notes and the guarantees are secured by a second lien or charge on substantially
all of the crude oil and natural gas properties and natural gas processing
plants owned by Abraxas, Canadian Abraxas, Sandia and Wamsutter, as well as the
shares of common stock of Grey Wolf owned by Abraxas and Canadian Abraxas. The
exchange offer reduced our long term debt by $76.6 million.


    In March 1999, Abraxas sold $63.5 million of its first lien notes to
refinance bank debt, meet near-term debt service requirements and make limited
capital expenditures. The first lien notes are senior obligations of Abraxas and
are jointly and severally guaranteed by Canadian Abraxas, Sandia and Wamsutter.


    In January 1999, Canadian Abraxas acquired all of the outstanding common
shares of New Cache Petroleums Ltd. for an aggregate purchase price of $78
million in cash and the assumption of approximately $10 million in debt. The
debt was repaid with a portion of the proceeds from the sale of the first lien
notes.

Primary Operating Areas

    Our U.S. operations are concentrated in South and West Texas with over 99%
of the PV-10 of our U.S. crude oil and natural gas properties at December 31,
1998 located in those two regions. We operate approximately 80% of our wells in
Texas.

                                       44
<PAGE>
South Texas

    Our operations in South Texas are concentrated along the Edwards Trend in
Live Oak and Dewitt Counties and in the Frio/Vicksburg area in San Patricio
County. We own an average 71% working interest in and operate 80% of our 115
wells. These properties had average daily production of 863 net Bbls of crude
oil and NGLs and 10,285 net Mcf of natural gas per day for the year ended
December 31, 1998, and 557 net Bbls of crude oil and NGLs and 12,679 net Mcf of
natural gas per day for the quarter ended September 30, 1999. During the first
ten months of 1999, we drilled a total of 4 new wells (4.0 net) in South Texas,
with a 100% success rate.

    Our wells in the Edwards Trend are characterized by high working interests
and are substantially all natural gas. We have identified numerous drilling
locations in the Edwards Trend and we believe that we have the necessary
technical expertise and significant competitive advantage over other operations
in the trend through our proprietary drilling techniques.

West Texas

    Our operations in West Texas are concentrated along the deep
Devonian/Ellenberger formation and shallow Cherry Canyon sandstones in Ward
County, the Spraberry Trend in Midland County and in the Sharon Ridge Clearfork
Field in Scurry County. We own an average 73% working interest in and operate
approximately 80% of our 264 wells. These properties had average daily
production of 1,264 net Bbls of crude oil and NGLs and 6,926 net Mcf of natural
gas per day for the year ended December 31, 1998, and 644 net Bbls of crude oil
and NGLs and 4,969 net Mcf of natural gas per day for the quarter ended
September 30, 1999. During the first ten months of 1999, we drilled a total of 4
new wells (3.9 net) in West Texas with a 100% success rate. Our wells in West
Texas have a drilling profile which is similar to that of the Edwards Trend we
have identified several drilling locations in West Texas. Recent successful
horizontal wells in similar fields by Texaco, Mobil, and Titan have enabled us
to properly delineate our drilling prospects.

Canada

    We own producing properties in Western Canada, consisting primarily of
natural gas reserves. We also own interests ranging from 10% to 100% in
approximately 200 miles of natural gas gathering systems and 19 natural gas
processing plants. As of December 31, 1998, on a pro forma basis, Canadian
Abraxas and New Cache had estimated net proved reserves of 175 Bcfe (82% natural
gas) with a PV-10 of $142.9 million, 97% of which was attributable to proved
developed reserves. For the year ended December 31, 1998, on a pro forma basis,
the properties produced an average of approximately 1,980 net Bbls of crude oil
and NGLs per day and 52,583 net Mcf of natural gas per day from 105.5 net wells.
For the quarter ended September 30, 1999, these properties had average daily
production of 1,472 net Bbls of crude oil and NGLs and 47,637 net Mcf of natural
gas per day. The natural gas processing plants had aggregate capacity of
approximately 306 gross MMcf of natural gas per day (121 net MMcf).

    Grey Wolf manages the operations of Canadian Abraxas pursuant to a
management agreement between Canadian Abraxas and Grey Wolf. Under the
management agreement, Canadian Abraxas reimburses Grey Wolf for reasonable costs
or expenses attributable to Canadian Abraxas and for administrative expenses
based upon the percentage that Canadian Abraxas' gross revenue bears to the
total gross revenue of Canadian Abraxas and Grey Wolf.

Exploratory and Developmental Acreage


    Our principal crude oil and natural gas properties consist of producing and
non-producing crude oil and natural gas leases, including reserves of crude oil
and natural gas in place. The following table indicates our interest in
developed and undeveloped acreage as of December 31, 1998, on a pro forma basis:

Reserves Information


    The crude oil and natural gas reserves of Abraxas have been estimated as of
December 31, 1998, by DeGolyer and MacNaughton, Dallas, Texas. The crude oil and
natural gas reserves of Canadian Abraxas have been estimated as of December 31,
1998, by McDaniel & Associates Consultants Ltd., Calgary, Alberta. The crude oil
and natural gas reserves of New Cache have been estimated by us as of December
31, 1998, and reviewed by McDaniel & Associates Consultants Ltd.,

    Calgary, Alberta. 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
our crude oil, NGLs and natural gas reserves as of December 31, 1996, 1997 and

    MMcf of natural gas in 1998.

    The process of estimating crude oil and natural gas reserves is complex and
involves decisions and assumptions in the evaluation of available geological,
geophysical, engineering and economic data. Therefore, these estimates are
imprecise.

    Actual future production, crude oil and natural gas prices, revenues, taxes,
development expenditures, operating expenses and quantities of recoverable crude
oil and natural gas reserves most likely will vary from those estimated. Any
significant variance could materially affect the estimated quantities and
present value of reserves set forth in this prospectus. In addition, we may
adjust estimates of proved reserves to reflect production history, results of
exploration and development, prevailing crude oil and natural gas prices and
other factors, many of which are beyond our control.

    You should not assume that the present value of future net revenues referred
to in prospectus is the current market value of our estimated crude oil and
natural gas reserves. In accordance with SEC requirements, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the end of the year of the estimate. Actual future prices
and costs may be materially higher or lower than the prices and costs as of the
end of the year of the estimate. Significant declines during 1998 in crude oil
and natural gas prices reduced our present value of future net revenues. Any
changes in consumption by natural gas purchasers or in governmental regulations


                                       47
<PAGE>
or taxation will also affect actual future net cash flows. The timing of both
the production and the expenses from the development and production of crude oil
and natural gas properties will affect the timing of actual future net cash
flows from proved reserves and their present value. For example, we reduced our
1999 capital expenditure budget. This reduction will delay cash flows and
thereby reduce present value. In addition, the 10% discount factor, which is
required by the SEC to be used in calculating discounted future net cash flows
for reporting purposes, is not necessarily the most accurate discount factor.
The effective interest rate at various times and the risks associated with us or
the crude oil and natural gas industry in general will affect the accuracy of
the 10% discount factor.

    The estimates of our reserves are based upon various 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 December 31, 1998. The average sales prices as of such date used
for purposes of such estimates except for New Cache were $9.95 per Bbl of crude
oil, $8.97 per Bbl of NGLs and $1.90 per Mcf of natural gas and the average
sales prices used for purposes of such estimate of New Cache were $10.42 per Bbl
of crude oil and $1.47 per Mcf of natural gas. It is also assumed that New Cache
will make future capital expenditures of approximately $0.8 million in the
aggregate, which are necessary to develop and realize the value of proved
undeveloped reserves on its properties. Any significant variance in actual
results from these assumptions could also materially affect the estimated
quantity and value of reserves set forth herein.


    We file reports of our 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 our operations is 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 we received for our crude oil and natural gas
production and the level of such production are subject to wide fluctuations and
depend on numerous factors beyond our 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 our proved reserves and our revenue,
profitability and cash flow from operations.

    In order to manage our exposure to price risks in the marketing of our crude
oil and natural gas, from time to time we have 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, we 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 our futures position and sell our production to a customer.
Such contracts may expose us to the risk of financial loss in certain
circumstances, including instances where production is less than expected, our
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 our ability to benefit from
unexpected increases in crude oil and natural gas prices. See "Management's
Discussion and Analysis of Financial Condition And Results of Operations --
Liquidity and Capital Resources."

    Substantially all of our 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, 1998, four purchasers accounted for approximately 58% of
our crude oil and natural gas sales. We believe that there are numerous other
companies available to purchase our crude oil and natural gas and that the loss
of any or all of these purchasers would not materially affect our ability to
sell crude oil and natural gas.

Competition

    We operate in a highly competitive environment. 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. We compete
with major and independent crude oil and natural gas companies for properties
and the equipment and labor required to develop and operate such properties.
Many of these competitors have financial and other resources substantially
greater than ours.

    The principal 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. We must compete for such resources with
both major crude oil and natural gas companies and independent operators.
Although we believe our current operating and financial resources are adequate
to preclude any significant disruption of our operations in the immediate future
we cannot assure you that such materials and resources will be available to us.


    We 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. Our principal competitors 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
ours. Smaller local distributors may enjoy a marketing advantage in their
immediate service areas.


    We compete against other companies in our natural gas processing business
both for supplies of natural gas and for customers to which we sell our
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


    Our 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.

    In the recent past, maximum selling prices for certain categories of crude
oil, natural gas, condensate and NGLs in the United States were subject to
federal regulation. In 1981, all federal price controls over sales of crude oil,
condensate and NGLs were lifted. In 1993, the Congress deregulated natural gas
prices for all "first sales" of natural gas. As a result, all sales of our
United States produced crude oil, natural gas, condensate and NGLs may be sold
at market prices, unless otherwise committed by contract.


    Crude oil and 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. Crude oil and 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.

                                       50

    The provincial governments of Alberta, British Columbia and Saskatchewan
also regulate the volume of natural gas that may be removed from these provinces
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.

United States Natural Gas Regulation


    Historically, interstate pipeline companies in the United States 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 us; 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," although many have affiliated marketers. In subsequent
orders, the FERC largely affirmed the major features of Order 636. 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. The federal appellate courts have largely affirmed the significant
features of Order No. 636 and numerous related orders pertaining to the
individual pipelines. We do not believe that Order 636 and the related
restructuring proceedings affect us any differently than other natural gas
producers and marketers with which we compete.

    In recent years the FERC also has pursued a number of other important policy
initiatives which could significantly affect the marketing of natural gas in the
United States. Some of the more notable of these regulatory initiatives include:

    (1) 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),

    (2) the completion of rule-making involving the regulation of pipelines with
marketing affiliates under Order No. 497,

    (3) various FERC orders adopting rules proposed by the Gas Industry
Standards Board which are designed to further standardize pipeline
transportation tariffs and business practices,

    (4) a notice of proposed rulemaking that, among other things, proposes (a)
to eliminate the cost-based price cap currently imposed on natural gas
transactions of less than one year in duration, (b) to establish mandatory
"transparent" capacity auctions of short-term capacity on a daily basis, and (c)
to permit interstate pipelines to negotiate terms and conditions of service with
individual customers,

                                       51
<PAGE>
    (5) a notice of inquiry which continues the FERC's review of its regulatory
policies with respect to the pricing of long-term pipeline transportation
services by presenting a range of questions to the industry dealing with current
cost-based pricing of new and existing capacity and alternative rate mechanism
options, including the desirability of pricing interstate pipeline capacity
utilizing market-based rates, incentive rates, or indexed rates, and

    (6) a notice of proposed rulemaking that proposes generic procedures to
expedite the FERC's handling of complaints against interstate pipelines with the
goals of encouraging and supporting consensual resolutions of complaints and
organizing the complaint procedures so that all complaints are handled in a
timely and fair manner.

    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, including us, as
a result of the monopolization of those facilities by their new, unregulated
owners. As to all of these FERC initiatives, the ongoing, or, in some instances,
preliminary and evolving nature of these regulatory initiatives makes it
impossible at this time to predict their ultimate impact on our business.
However, we do not believe that these FERC initiatives will affect us any
differently than other natural gas procedures and marketers with which we
compete.

    Since Order 636 FERC decisions involving onshore facilities 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." We ship certain of our natural gas through gathering facilities
owned by others, including interstate pipelines, under existing long term
contractual arrangements. Although these FERC decisions have created the
potential for increasing the cost of shipping our gas on third party gathering
facilities, our shipping activities have not been materially affected by these
decisions.

    Commencing in October 1993, the FERC issued a series of rules (Order Nos.
561 and 561-A) establishing an indexing system under which oil pipelines will be
able to change their transportation rates, subject to prescribed ceiling levels.
The indexing system, which allows or may require pipelines to make rate changes
to track changes in the Producer Price Index for Finished Goods, minus one
percent, became effective January 1, 1995. In certain circumstances, these rules
permit oil pipelines to establish rates using traditional cost of service or
other methods of rate making. We do not believe that these rules affect us any
differently than other crude oil producers and marketers with which we compete.

    Additional proposals and proceedings that might affect the natural gas
industry in the United States are considered from time to time by Congress, the
FERC, state regulatory bodies and the courts. We cannot predict when or if any
such proposals might become effective or their effect, if any, on our
operations. The oil and gas industry historically has been very heavily
regulated; thus there is no assurance that the less stringent regulatory
approach recently pursued by the FERC and Congress will continue indefinitely
into the future.


State and Other Regulation


    All of the jurisdictions in which we own 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. Our 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 and provinces allow
the forced pooling or integration of tracts to facilitate exploration while
other states and provinces rely on voluntary pooling of lands and leases. In


                                       52
<PAGE>
addition, state and provincial 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 we can produce from our wells, and to limit the number
of wells or the location at which we can drill.


    State and provincial regulation of gathering facilities generally includes
various safety, environmental, and in some circumstances, non-discriminatory
take requirements, but does not generally entail rate regulation. In the United
States, 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, on August 19, 1997, the Texas
Railroad Commission enacted a Natural Gas Transportation Standards and Code of
Conduct to provide regulatory support for the State's more active review of
rates, services and practices associated with the gathering and transportation
of gas by an entity that provides such services to others for a fee, in order to
prohibit such entities from unduly discriminating in favor of their affiliates.


    In the event we conduct operations on federal or Indian oil and gas leases,
such operations must comply with numerous regulatory restrictions, including
various non-discrimination statutes, and certain of such operations must be
conducted pursuant to certain on-site security regulations and other permits
issued by various federal agencies. In addition, in the United States, the
Minerals Management Service ("MMS") has recently issued a final rule to clarify
the types of costs that are deductible transportation costs for purposes of
royalty valuation of production sold off the lease. In particular, MMS will not
allow deduction of costs associated with marketer fees, cash out and other
pipeline imbalance penalties, or long-term storage fees. Further, the MMS has
been engaged in a three-year process of promulgating new rules and procedures
for determining the value of oil produced from federal lands for purposes of
calculating royalties owed to the government. The oil and gas industry as a
whole has resisted the proposed rules under an assumption that royalty burdens
will substantially increase. We cannot predict what, if any, effect any new rule
will have on our operations.


Canadian Royalty Matters

    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 horizontal extensions commenced at least five years
after the well was originally spudded may qualify for a royalty reduction. A
24-month, 8,000 cubic metres exemption is available to production from a well
that has not produced for a 12-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
CDN$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%.



                                       53
<PAGE>
    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. On December 22, 1997, the Government of Alberta gave notice that they
intended to review the ARTC program with expected changes to take effect prior
to 2001.

    The Government of Saskatchewan's fiscal regime for the oil and gas industry
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 meters of oil in the case of deep exploratory
wells). The maximum royalty applicable to the first 12,000 cubic meters 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 meters 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 5 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 meters of natural gas produced will be subject to an incentive maximum
royalty rate of 5%. On February 9, 1998, the Government of Saskatchewan
announced further royalty incentive programs to encourage oil and gas
exploration.

    Producers of oil and natural gas in British Columbia are also required to
pay annual rental payments in respect of Crown leases and royalties and freehold
production taxes in respect of oil and gas produced from Crown and freehold
lands respectively. The amount payable as a royalty in respect of oil depends on
the vintage of the oil (whether it was produced from a pool discovered before or
after October 31, 1975), the quantity of oil produced in a month and the value
of the oil. Oil produced from newly discovered pools may be exempt from the
payment of a royalty for the first 36 months of production. The royalty payable
on natural gas is determined by a sliding scale based on a reference price which
is the greater of the amount obtained by the producer and at prescribed minimum
price. Gas produced in association with oil has a minimum royalty of 8% while
the royalty in respect of other gas may not be less than 15%.

Environmental Matters


    Our operations are subject to numerous federal, state, provincial and local
laws and regulations controlling the generation, use, storage, and discharge of
materials into the environment or otherwise relating to the protection of the
environment. These laws and regulations may require the acquisition of a permit
or other authorization before construction or drilling commences; restrict the
types, quantities, and concentrations of various substances that can be released
into the environment in connection with drilling, production, and gas processing
activities; suspend, limit or prohibit construction, drilling and other


                                       54
<PAGE>
activities in certain lands lying within wilderness, wetlands, and other
protected areas; require remedial measures to mitigate pollution from historical
and on-going operations such as use of pits and plugging of abandoned wells;
restrict injection of liquids into subsurface strata that may contaminate
groundwater; and impose substantial liabilities for pollution resulting from our
operations. Environmental permits required for our operations may be subject to
revocation, modification, and renewal by issuing authorities. Governmental
authorities have the power to enforce compliance with their regulations and
permits, and violations are subject to injunction, civil fines, and even
criminal penalties. Our management believes that we are in substantial
compliance with current environmental laws and regulations, and that we will not
be required to make material capital expenditures to comply with existing laws.
Nevertheless, changes in existing environmental laws and regulations or
interpretations thereof could have a significant impact on us as well as the oil
and gas industry in general, and thus we are unable to predict the ultimate cost
and effects of future changes in environmental laws and regulations.

    In the United States, the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA"), also known as "Superfund," and comparable state
statutes impose strict, joint, and several liability on certain classes of
persons who are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
a disposal site or sites where a release occurred and companies that generated,
disposed or arranged for the disposal of the hazardous substances released at
the site. Under CERCLA such persons or companies may be retroactively liable for
the costs of cleaning up the hazardous substances that have been released into
the environment and for damages to natural resources, and it is common for
neighboring land owners and other third parties to file claims for personal
injury, property damage, and recovery of response costs allegedly caused by the
hazardous substances released into the environment. The Resource Conservation
and Recovery Act ("RCRA") and comparable state statutes govern the disposal of
"solid waste" and "hazardous waste" and authorize imposition of substantial
civil and criminal penalties for failing to prevent surface and subsurface
pollution, as well as to control the generation, transportation, treatment,
storage and disposal of hazardous waste generated by oil and gas operations.
Although CERCLA currently contains a "petroleum exclusion" from the definition
of "hazardous substance," state laws affecting our operations impose cleanup
liability relating to petroleum and petroleum related products, including crude
oil cleanups. In addition, although RCRA regulations currently classify certain
oilfield wastes which are uniquely associated with field operations as
"non-hazardous," such exploration, development and production wastes could be
reclassified by regulation as hazardous wastes thereby administratively making
such wastes subject to more stringent handling and disposal requirements.

    We currently own or lease, and have in the past owned or leased, numerous
properties that for many years have been used for the exploration and production
of oil and gas. Although we utilized standard industry operating and disposal
practices at the time, hydrocarbons or other wastes may have been disposed of or
released on or under the properties we owned or leased or on or under other
locations where such wastes have been taken for disposal. In addition, many of
these properties have been operated by third parties whose treatment and
disposal or release of hydrocarbons or other wastes was not under our control.
These properties and the wastes disposed thereon may be subject to CERCLA, RCRA,
and analogous state laws. Our operations are also impacted by regulations
governing the disposal of naturally occurring radioactive materials ("NORM"). We
must comply with the Clean Air Act and comparable state statutes which prohibit
the emissions of air contaminants, although a majority of our activities are
exempted under a standard exemption. Moreover, owners, lessees and operators of
oil and gas properties are also subject to increasing civil liability brought by
surface owners and adjoining property owners. Such claims are predicated on the
damage to or contamination of land resources occasioned by drilling and
production operations and the products derived therefrom, and are usually causes
of action based on negligence, trespass, nuisance, strict liability and fraud.

    United States federal regulations also require certain owners and operators
of facilities that store or otherwise handle oil, such as us, to prepare and
implement spill prevention, control and countermeasure plans and spill response
plans relating to possible discharge of oil into surface waters. The federal Oil
Pollution Act ("OPA") contains numerous requirements relating to prevention of,
reporting of, and response to oil spills into waters of the United States. For
facilities that may affect state waters, OPA requires an operator to demonstrate
$10 million in financial responsibility. State laws mandate crude oil cleanup
programs with respect to contaminated soil.



                                       55
<PAGE>
    Our Canadian operations are also subject to environmental regulation
pursuant to local, provincial and federal legislation which generally require
operations to be conducted in a safe and environmentally responsible manner.
Canadian environmental legislation provides for restrictions and prohibitions
relating to the discharge of air, soil and water pollutants and other substances
produced in association with certain crude oil and natural gas industry
operations, and environmental protection requirements, including certain
conditions of approval and laws relating to storage, handling, transportation
and disposal of materials or substances which may have an adverse effect on the
environment. Environmental legislation 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.

    Certain federal environmental laws that may affect us include the Canadian
Environmental Assessment Act which ensures that the environmental effects of
projects receive careful consideration prior to licenses or permits being
issued, to ensure that projects that are to be carried out in Canada or on
federal lands do not cause significant adverse environmental effects outside the
jurisdictions in which they are carried out, and to ensure that there is an
opportunity for public participation in the environmental assessment process;
the Canadian Environmental Protection Act ("CEPA") which is the most
comprehensive federal environmental statute in Canada, and which controls toxic
substances (broadly defined), includes standards relating to the discharge of
air, soil and water pollutants, provides for broad enforcement powers and
remedies and imposes significant penalties for violations; the National Energy
Board Act which can impose certain environmental protection conditions on
approvals issued under the Act; the Fisheries Act which prohibits the depositing
of a deleterious substance of any type in water frequented by fish or in any
place under any condition where such deleterious substance may enter any such
water and provides for significant penalties; the Navigable Waters Protection
Act which requires any work which is built in, on, over, under, through or
across any navigable water to be approved by the Minister of Transportation, and
which attracts severe penalties and remedies for non-compliance, including
removal of the work.


    In Alberta, environmental compliance has been governed by the Alberta
Environmental Protection and Enhancement Act ("AEPEA") since September 1, 1993.
In addition to consolidating a variety of environmental statutes, the AEPEA also
imposes certain new environmental responsibilities on oil and natural gas
operators in Alberta. The AEPEA sets out environmental standards and compliance
for releases, clean-up and reporting. The Act provides for a broad range of
liabilities, enforcement actions and penalties.

    British Columbia's Environmental Assessment Act became effective June 30,
1995. This legislation rolls the previous processes for the review of major
energy projects into a single environmental assessment process which
contemplates public participation in the environmental review.

    Saskatchewan's Environmental Management and Protection Act is the primary
environmental legislation for that province. This Act provides significant
enforcement and penalty provisions, and includes a compensation scheme
respecting losses or damage from spills. The Clean Air Act provides a permitting
scheme for certain industrial activities, broad enforcement provisions and
significant penalties for non-compliance. The Environmental Assessment Act
provides that certain development activities which can affect the environment
must undergo environmental assessment and approval from the provincial
government.


    We are not currently involved in any administrative, judicial or legal
proceedings arising under domestic or foreign federal, state, or local
environmental protection laws and regulations, or under federal or state common
law, which would have a material adverse effect on our financial position or
results of operations. Moreover, we maintain insurance against costs of clean-up
operations, but we are not fully insured against all such risks. A serious
incident of pollution may, as it has in the past, also result in the suspension
or cessation of operations in the affected area.

    We have a Corporate Environmental Policy and a detailed Environmental
Management System in place to ensure continued compliance with environmental,
health and safety laws and regulations. We believe that we have obtained and are
in compliance with all material environmental permits, authorizations and
approvals.

Title to Properties


    As is customary in the crude oil and natural gas industry, we make only a
cursory review of title to undeveloped crude oil and natural gas leases at the
time we acquire them. However, before drilling commences, we require a thorough
title search to be conducted, and any material defects in title are remedied
prior to the time actual drilling of a well begins. To the extent title opinions
or other investigations reflect title defects, we, rather than the seller of the
undeveloped property, are typically obligated to cure any title defect at our
expense. If we 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, we
could suffer a loss of our entire investment in the property. We believe that we
have good title to our crude oil and natural gas properties, some of which are
subject to immaterial encumbrances, easements and restrictions. The crude oil
and natural gas properties we own are also typically subject to royalty and
other similar non-cost bearing interests customary in the industry. We do not
believe that any of these encumbrances or burdens will materially affect our
ownership or use of our properties.

Employees


    As of February 1, 2000, we had 48 full-time employees, including 3 executive
officers, 2 non-executive officers, 4 petroleum engineers, 1 geologist, 5
managers, 9 secretarial and clerical personnel and 24 field personnel.
Additionally, we retain contract pumpers on a month-to-month basis. We retain
independent geological and engineering consultants from time to time on a
limited basis and expects to continue to do so in the future.

    As of February 1, 2000, Grey Wolf had 43 full-time employees, including 4
executive officers, 2 non-executive officers, 1 manager, 2 petroleum engineers,
4 geologists, 1 geophysicist, 15 secretarial and clerical personnel and 14 field
personnel.


Office Facilities


    Our executive and administrative offices are located at 500 North Loop 1604
East, Suite 100, San Antonio, Texas 78232. We also have an office in Midland,
Texas. These offices, consisting of approximately 12,650 square feet in San
Antonio and 960 square feet in Midland, are leased until March 2005 at an
aggregate rate of $18,000 per month.


    Canadian Abraxas leases 7,427 square feet of office space in Calgary,
Alberta pursuant to a lease which expires on July 1, 2001.

    Grey Wolf leases 8,683 square feet of office space in Calgary, Alberta
pursuant to a lease which expires on December 31, 2001.

Other Properties


    We own 10 acres of land, an office building, workshop, warehouse and house
in Sinton, Texas, 160 acres of land in Coke County, Texas and a 50% interest in
approximately two acres of land in Bexar County, Texas. All three properties are
used for the storage of tubulars and production equipment. We also own 19
vehicles which are used in the field by employees.


Litigation


    General. From time to time, we are involved in litigation relating to claims
arising out of our operations in the normal course of business. We are not
currently engaged in any legal proceedings that are expected, individually or in
the aggregate, to have a material adverse effect on us.

    Hornburg Litigation. In May 1995, certain plaintiffs filed a lawsuit against
us alleging negligence and gross negligence, tortious interference with
contract, conversion and waste. In March 1998, a jury found against us and on
May 22, 1998 final judgment in the amount of $1.3 million was entered. We have
filed an appeal. Management believes that the plaintiffs' claims are without
merit and that damages should not be recoverable under this action; however, the
ultimate effect on our financial position and results of operations cannot be
determined at this time. We have not established a reserve for this matter at
December 31, 1998.

Enforceability Of Civil Liabilities Against Foreign Persons

    Canadian Abraxas is an Alberta corporation, certain of its officers and
directors may be residents of various jurisdictions outside the United States
and its Canadian counsel, Osler, Hoskin & Harcourt, LLP, 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

Long Term Incentive Plan Awards During the Fiscal Year Ended December 31, 1998


    We did not make any awards to any of Messrs. Watson, Williford, Carington,
Patterson and Wendel under a long term incentive plan during the fiscal year
ended December 31, 1998.


Employment Agreements


    We have entered into employment agreements with each of Messrs. Watson,
Williford, Carington and Wendel as well as with Dr. Lee T. Billingsley, Abraxas'
Vice President of Exploration, pursuant to which each of Messrs. Watson,
Williford, Carington, Wendel and Dr. Billingsley will receive compensation as
determined from time to time by the Board in its sole discretion

    The employment agreements for Messrs. Watson, Williford, and Carington are
scheduled to terminate on December 21, 2002, and shall be automatically extended
for additional one-year terms unless we give Messrs. Watson, Williford, and
Carington 120 days notice prior of the expiration of the original term or any
extension thereof of its intention not to renew the employment agreement. If,
during the term of Messrs. Watson's, Williford's and Carington's employment
agreements, Messrs. Watson, Williford or Carington's employment is terminated
other than for cause or disability, by reason of Messrs. Watson's, Williford's
or Carington's death or retirement or by Messrs. Watson, Williford or Carington,
as the case may be, other than for good reason, then Messrs. Watson, Williford
and Carington will be entitled to receive a lump sum payment equal to the
greater of (a) his annual base salary for the last full year during which he was
employed by us or (b) his annual base salary for the remainder of the term of
each of his respective employment agreements.


                                       65
<PAGE>
    If a change of control occurs during the term of Messrs. Watson's
Williford's and Carington's employment agreements, and if subsequent to such
change of control, Messrs. Watson, Williford, or Carington's employment is
terminated other than for cause or disability by reason of Messrs. Watson's,
Williford's or Carington's death or retirement or by Messrs. Watson, Williford
or Carington, as the case may be, other than for good reason, then Mr. Watson
will be entitled to the following:

         (1) if such termination occurs prior to the end of the first year of
the initial term of his employment agreement, a lump sum payment equal to five
(5) times his annual base salary;

         (2) if such termination occurs after the end of the first year of the
initial term of his employment agreement but prior to the end of the second year
of the initial term of his employment agreement, a lump sum payment equal to
four (4) times his annual base salary;

         (3) if such termination occurs after the end of the second year of the
initial term of his employment agreement but prior to the end of the third year
of the initial term of his employment agreement, a lump sum payment equal to
three (3) times his annual base salary; and


         (4) if such termination occurs after the end of the third year of the
initial term of his employment agreement a lump sum payment equal to 2.99 times
his annual base salary.

         Under such circumstances, Messrs. Williford and Carington will be
entitled to the following:

         (1) if such termination occurs prior to the end of the first year of
the initial term of his respective employment agreement, a lump sum payment
equal to four (4) times his annual base salary;


         (2) if such termination occurs after the end of the first year of the
initial term of his respective employment agreement but prior to the end of the
second year of the initial term of his respective employment agreement, a lump
sum payment equal to three (3) times his annual base salary; and

         (3) if such termination occurs after the end of the second year of the
initial term of his respective employment agreement, a lump sum payment equal to
2.99 times his annual base salary.


         The employment agreements for Mr. Wendel and Dr. Billingsley,
originally scheduled to terminate on December 31, 1998, have been automatically
extended for three years and will terminate on December 31, 2000, and may be
automatically extended for an additional year if by December 1 of the prior year
neither us nor Mr. Wendel or Dr. Billingsley, as the case may be, has given
notice that he or it, as the case may be, 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. Wendel's and Dr. Billingsley's employment is
at will and may be terminated by us 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. Wendel's and Dr. Billingsley'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. Wendel's or Dr. Billingsley's employment is terminated
other than for cause or disability by reason of Mr. Wendel's or Dr.
Billingsley's death or retirement or by Mr. Wendel or Dr. Billingsley, as the
case may be, other than for good reason, then Mr. Wendel and Dr. Billingsley
will each be entitled to receive a lump sum payment equal to three times his
annual base salary.


         If any lump sum payment to Messrs. Watson, Williford, Carington, Wendel
or Dr. Billingsley would individually or together with any other amounts paid or
payable constitute an "excess parachute payment" within the meaning of Section
280G of the Internal Revenue Code of 1986, as amended, and applicable
regulations thereunder, the amounts to be paid will be increased so that Messrs.
Watson, Williford, Carington, Wendel or Dr. Billingsley, as the case may be,
will be entitled to receive the amount of compensation provided in his contract
after payment of the tax imposed by Section 280G.

                              CERTAIN TRANSACTIONS


         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 our employees from time to time at Wind River's
cost. We paid Wind River a total of $302,289 for use of the plane during 1998.


         Grey Wolf owns a 10% interest in certain producing properties owned by
Canadian Abraxas and in Canadian Abraxas' natural gas processing plants and
manages the operations of Canadian Abraxas pursuant to a management agreement
between Canadian Abraxas and Grey Wolf. Under the management agreement, Canadian
Abraxas reimburses Grey Wolf for reasonable costs or expenses attributable to
Canadian Abraxas and for administrative expenses based upon the percentage that
Canadian Abraxas' gross revenue bears to the total gross revenue of Canadian
Abraxas and Grey Wolf. In 1998, Canadian Abraxas paid CDN $1,485.155 to Grey
Wolf pursuant to the management agreement.

         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.

(1)     Unless otherwise indicated, all shares are held directly with sole

(2)     2,957,549 shares of common stock beneficially owned by various Halcyon
        limited partnerships managed by Halcyon/Alan B. Slifka Management
        Company LLC, over which the manager disclaims beneficial ownership, as
        reported on Schedule 13G filed with the SEC on January 6, 2000. An
        additional 509,260 shares of common stock are owned by a Halcyon limited
        partnership managed by an affiliate of Halcyon/Alan B. Slifka Management
        Company LLC, over which such affiliate disclaims beneficial ownership.

(3)     Owned by one or more open or closed-end investment companies or other
        managed accounts which are advised by direct and indirect investment
        advisory subsidiaries (the "Adviser Subsidiaries") of Franklin
        Resources, Inc. ("FRI"). Such advisory contracts grant to such Adviser
        Subsidiaries all investment and/or voting power over the securities
        owned by such advisory clients.

        The voting and investment powers held by Franklin Mutual Advisers, LLC
        ("FMA"), formerly Franklin Mutual Advisers, Inc., an indirect wholly
        owned investment advisory subsidiary of FRI, are exercised independently
        from FRI and from all other investment advisor subsidiaries of FRI (FRI,
        its affiliates and investment advisor subsidiaries other than FMA are
        collectively referred to herein as "FRI affiliates"). Furthermore, FMA
        and FRI internal policies and procedures establish informational
        barriers that prevent the flow between FMA and the FRI affiliates of
        information that relates to the voting and investment powers over the
        securities owned by their respective advisory clients.

        Charles B. Johnson and Rupert H. Johnson, Jr. (the "Principal
        Shareholders") each own in excess of 10% of the outstanding Common Stock
        of FRI and are the principal shareholders of FRI. FRI and the Principal
        Shareholders may be deemed to be, for purposes of Rule 13d-3 under the
        Securities and Exchange Act of 1934, the beneficial owner of securities
        held by persons and entities advised by FRI subsidiaries. FRI, the
        Principal Shareholders and each of the Adviser Subsidiaries disclaim any
        economic interest of beneficial ownership in any of the securities
        covered by this statement.

        FRI, the Principal Shareholders, and each of the Adviser Subsidiaries
        are of the view that they are not acting as a "group" for purposes of
        Section 13(d) under the 1934 Act and that they are not otherwise
        required to attribute to each other the "beneficial ownership" of
        securities held by any of them or by any persons or entities advised by
        FRI subsidiaries.

         Since 1993, Jefferies has acted in various material roles relating to
us. Jefferies acted as one of the initial purchasers in the sale of the old
notes, as the initial purchaser of the first lien notes and served as our
financial advisor during the recent exchange offer.

         At our request and cost, Houlihan acted as financial advisor to an
informal committee of holders of the old notes during the exchange offer. Other
than such role, Houlihan has not had any material relationships with us.

         The second lien notes, Abraxas common stock and contingent value rights
offered pursuant to this prospectus were issued to Jefferies and Houlihan as
payment of fees and expenses related to the exchange offer. In connection with
such issuance, Jefferies and Houlihan were granted registration rights covering
the second lien notes, Abraxas common stock and contingent value rights pursuant
to a registration rights agreement, a form of which is filed as an exhibit to
the registration statement of which this prospectus is a part. This registration
statement is intended to satisfy such registration rights.

                              PLAN OF DISTRIBUTION

         This prospectus covers the resale of the second lien notes, the shares
of Abraxas common stock and the contingent value rights by the selling security
holders. The selling security holders may sell their second lien notes, shares
of Abraxas common stock and contingent value rights under this prospectus:

         o    through one or more broker-dealers acting as either principal or
              agent;
         o    through underwriters;
         o    directly to investors; or
         o    any combination of these methods.

The selling security holders will fix a price or prices, and they may change the
price, of the second lien notes, shares of Abraxas common stock and contingent
value rights offered based upon:

         o    market prices prevailing at the time of sale;
         o    prices related to those market prices; or
         o    negotiated prices.

These sales may be effected in one or more of the following transactions (which
may involve crosses and block transactions):

         o    on any securities exchange or U.S. inter-dealer system of a
              registered national securities association on which the common
              stock may be listed or quoted at the time of sale;
         o    in the over-the-counter market;
         o    in private transactions;
         o    through the writing of options, whether the options are listed on
              an
         o    option exchange or otherwise; or
         o    through the settlement of short sales.

         Broker-dealers, underwriters or agents may receive compensation in the
form of discounts, concessions from the selling security holders or the
purchasers. These discounts, concessions or commissions may be more than those
customary for the transaction involved. If any broker-dealer purchases the
notes, shares of common stock or contingent value rights as principal, it may
effect resales of the shares through other broker-dealers, and other
broker-dealers may receive compensation from the purchasers for whom they act as
agents.

         To comply with the securities laws of some states, if applicable, the
securities may be sold in these jurisdictions only through registered or
licensed brokers or dealers. In addition, in some states the securities may not
be sold unless they have been registered or qualified for sale or an exemption
from registration or qualification requirements is available and is complied
with.

         The selling security holders and any underwriters, broker-dealers or
agents that participate in the sale of the securities may be "underwriters"
within the meaning of the Securities Act. Any discounts, commissions,
concessions or profit they earn on any resale of the shares may be underwriting
discounts and commissions under the Securities Act. Selling security holders who
are "underwriters" within the meaning of the Securities Act will be subject to
the prospectus delivery requirements of the Securities Act.

         Any securities covered by this prospectus which qualify for sale under
Rule 144 of the Securities Act may be sold under Rule 144 rather than under this
prospectus. A selling security holder may not sell any securities described in
this prospectus and may not transfer, devise or gift these securities by other
means not described in this prospectus.

         To the extent required, the specific securities to be sold, the names
of the selling security holders, the respective purchase prices and public


                                       71
<PAGE>
offering prices, the names of any agent, dealer or underwriter, and any
applicable commissions or discounts with respect to a particular offer will be
set forth in an accompanying prospectus supplement or, if appropriate, a
post-effective amendment to the registration statement of which this prospectus
is a part.

         Under Abraxas' registration rights agreement with the selling security
holders, we have agreed to indemnify the selling security holders and each
underwriter, if any, against certain liabilities, including certain liabilities
under the Securities Act, or will contribute to payments the selling security
holders or underwriters may be required to make in respect of those liabilities.

         We have agreed to pay substantially all of the expenses in connection
with the registration, offering and sale of the securities covered by this
prospectus, other than commissions, fees and discounts of underwriters, brokers,
dealers and agents.

         We have agreed to keep the registration statement, of which this
prospectus is a part, effective for one year from the time this registration
statement becomes effective, subject to extension for any suspension or blackout
periods during which securities covered by this prospectus can not be sold.


                      DESCRIPTION OF THE SECOND LIEN NOTES

    You can find definitions of certain terms used in this description under the
subheading "Certain Definitions." In this description, the word "Issuers" refer
to Abraxas and Canadian Abraxas and not to any of their subsidiaries.

    The Issuers issued the second lien notes under an indenture entered into
among the Issuers, the Subsidiary Guarantors and Firstar Bank, National
Association, as Trustee . The indenture is governed by certain provisions
contained in the Trust Indenture Act of 1939, as amended. The terms of the
second lien notes include those stated in the indenture and those made part of
the indenture by reference to the Trust Indenture Act.


    The indenture provides for issuance of up to $196.8 million of second lien
notes. The Issuers issued an aggregate principal amount of approximately $188.8
million of second lien notes in exchange for the old notes in the exchange offer
and $5.0 million in payment of certain fees incurred in connection with the
exchange offer. The following description is a summary of the material
provisions of the second lien notes, the indenture and the documents providing
for the security interests of the holders of the second lien notes. It does not
restate those agreements in their entirety. We urge you to read the indenture
and the security documents because they, not this description, define your
rights as holders of the second lien notes. A copy of the form of indenture and
the security documents may be obtained from the Issuers.


Brief Description of the Second Lien Notes and the Guarantees

The Second Lien Notes

    The second lien notes:

    o   are general obligations of the Issuers;

    o   are secured by a second lien and a second fixed or floating charge on
        substantially all of the Oil and Gas Assets of Abraxas and its Wholly
        Owned Restricted Subsidiaries and the common stock of Grey Wolf owned by
        the Issuers;

    o   rank equally with all of the Issuers' current and future senior
        Indebtedness;

    o   rank senior to all of the Issuers' current future Subordinated
        Indebtedness; and

                                       72
<PAGE>
    o   are be unconditionally guaranteed by the Subsidiary Guarantors.

The Guarantees

    The second lien notes are jointly and severally guaranteed (the
"Guarantees") by the following subsidiaries of the Issuers:

    o   Sandia; and

    o   Wamsutter.

        The Guarantees of the second lien notes:

    o   are general obligations of each Subsidiary Guarantor;

    o   are senior in right of payment to all existing and future Subordinated
        Indebtedness of each Subsidiary Guarantor;

    o   are on an equal basis with all existing and future Senior Indebtedness
        of each Subsidiary Guarantor;

    o   are secured by a second lien or charge on all of the Oil and Gas Assets
        of the Subsidiary Guarantors; and

    o   are limited for each Subsidiary Guarantor to the maximum amount which
        will result in each Guarantee's not being a fraudulent conveyance or
        fraudulent transfer.

    Each Subsidiary Guarantor that makes a payment or distribution under its
Guarantee will be entitled to a contribution from each other Subsidiary
Guarantor in a prorata amount based on the net assets of each Subsidiary
Guarantor.

    Each Subsidiary Guarantor may consolidate with or merge into or sell its
assets to the Issuers 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 the description of the
covenant in "Merger, Consolidation and Sale of Assets" below. In the event all
of the Capital Stock of a Subsidiary Guarantor is sold by the Issuers and/or one
or more of their Restricted Subsidiaries and the sale complies with the
provisions set forth in "Limitation on Asset Sales," such Subsidiary Guarantor's
Guarantee and any related Collateral will be released.

Principal, Maturity and Interest

    The indenture provides for the issuance of up to $196.8 million of second
lien notes thereunder. The second lien notes are issued in full registered form
only, without coupons, in denominations of $1,000 and integral multiples of
$1,000. The second lien notes mature on November 1, 2004.

    Interest on the second lien notes accrues at the rate of 11.5% per annum and
is payable semi-annually on each November 1 and May 1, commencing on May 1,
2000, to the Persons who are registered holders at the close of business on the
April 15 and October 15 immediately preceding the applicable interest payment
date. Interest shall accrue and be payable both before and after the filing of
any bankruptcy petition at the rate of 11.5% per annum.

    Interest on the second lien notes accrues from and including the most recent
date to which interest has been paid on the old notes with interest beginning to
accrue on November 1, 1999. Interest is computed on the basis of a 360-day year
comprised of twelve 30-day months.

Payment of Taxes

    All payments made by Canadian Abraxas or any Subsidiary Guarantor under or
with respect to the second lien notes or its Subsidiary Guarantee will be made


                                       73
<PAGE>
free and clear of any tax, duty, levy, impost, assessment or other Canadian
government or provincial charges. These items are sometimes collectively called
"Taxes" in this "Description of the Second Lien Notes."

    If Canadian Abraxas or any Subsidiary Guarantor or any successor, as the
case may be, were required to withhold or deduct any Taxes from any payment made
under or with respect to the second lien notes or any Subsidiary Guarantee,
Canadian Abraxas or such Subsidiary Guarantor, as the case may be, will pay such
additional amounts ("Additional Amounts") as may be necessary so that the net
amount received by each holder (including Additional Amounts) after such
withholding or deduction will not be less than the amount the holder would have
received if such Taxes had not been withheld or deducted. However, no Additional
Amounts will be payable with respect to a payment made to a holder (an "Excluded
Holder") in respect of a beneficial owner:

    o   with which the Issuers or such Subsidiary Guarantor does not deal at
        arm's-length (within the meaning of the Income Tax Act (Canada)) at the
        time of making such payment; or

    o   which is subject to such Taxes by reason of its being connected with
        Canada or any province or territory thereof otherwise than by the mere
        acquisition, holding or disposition of the second lien notes or the
        receipt of payments thereunder.

    Canadian Abraxas and the Subsidiary Guarantors will also:

    o   make such withholding or deduction; and

    o   remit the full amount deducted or withheld to the relevant governmental
        authority in accordance with applicable law.

    If Canadian Abraxas and the Subsidiary Guarantors pay these Taxes, they will
furnish certified copies of tax receipts evidencing such payment within 30 days
of payment to the holders.

    Canadian Abraxas and the Subsidiary Guarantors will, jointly and severally,
indemnify and hold harmless each holder (other than an Excluded Holder) and upon
written request reimburse each such holder for the amount of :

    o   any Taxes so levied or imposed on and paid by such holder as a result of
        payments made under or with respect to the second lien notes or any
        Subsidiary Guarantee,

    o   any liability (including penalties, interest and expenses) arising
        therefrom or with respect thereto, and

    o   any Taxes imposed with respect to any reimbursement under the two
        clauses above so that the net amount received by such holder after such
        reimbursement will not be less than the net amount the holder would have
        received if Taxes on such reimbursement had not been imposed.

    Whenever in the Indenture there is mentioned, in any context, the payment of
principal (and premium, if any), redemption price, Change of Control payment,
purchase price, interest or any other amount payable under or with respect to
any of the second lien notes, it also includes the payment of Additional Amounts
to the extent that, in such context, Additional Amounts are, were or would be
payable.

    The Issuers will also pay any present or future stamp, court or documentary
taxes or any other excise or property taxes, charges or similar levies that
arise in any jurisdiction from the execution, delivery, enforcement or
registration of the second lien notes or any other document or instrument in
relation thereto, or from the receipt of any payments with respect to the second
lien notes, excluding such taxes, charges or similar levies imposed by any
jurisdiction outside of Canada, the jurisdiction of incorporation of any
successor of either of the Issuers or any jurisdiction in which a paying agent
is located, and have agreed to indemnify the holders for any such taxes paid by
such holders.

    The foregoing obligations will survive any termination, defeasance or
discharge of the indenture and the payment of all amounts owing under or with
respect to the second lien notes and any Subsidiary Guarantee.

                                       74

Paying Agent and Registrar; Transfer and Exchange

    Initially, the Trustee will act as registrar for the second lien notes and
as paying agent. The second lien notes may be presented for registration of
transfer and exchange at the office of the registrar, which currently is the
Trustee's corporate trust office at 101 East 5th Street, St. Paul, Minnesota
55101. The Issuers will pay principal (and premium, if any) and interest on the
second lien notes at the office of the paying agent in the Borough of Manhattan
in the City of New York, State of New York. In addition, in the event the second
lien notes do not remain in book-entry form, interest may be paid, at the
Issuers' option, by wire transfer or check mailed to the registered addresses of
the holders as shown on the note register. The Issuers may change the paying
agent and registrar without notice to holders of the second lien notes. The
second lien notes will be treated as a single class of securities under the
indenture.

Redemption

Optional Redemption

    The Issuers may redeem the second lien notes, at their option, in whole at
any time or in part from time to time, on and after December 1, 2000, at the
redemption prices expressed as percentages of the principal amount set forth
below. If the Issuers redeem the second lien notes, the Issuers must also pay
interest accrued and unpaid to the applicable redemption date. The redemption
prices during the twelve-month period beginning on December 1 of the years
indicated are set forth below:

                  Year                                    Percentage

                  2000..................................    105.750%
                  2001..................................    102.875%
                  2002 and thereafter...................    100.000%

    In addition, prior to December 1, 2000, the Issuers may redeem up to 50% of
the aggregate principal amount of the second lien notes at a redemption price of
111.50% of the principal amount, plus accrued and unpaid interest to the date of
redemption with the net proceeds of one or more Equity Offerings. The Issuers
may not cause a redemption from the proceeds of an Equity Offering unless:

    o   at least 50% of the aggregate principal amount of the second lien notes
        remains outstanding immediately after giving effect to any such
        redemption (with second lien notes owned by the Issuers or any of their
        Affiliates deemed not to be outstanding); and

    o   redemption occurs within 60 days after the consummation of any such
        Equity Offering.

    If the Issuers redeem less than all of the second lien notes, selection of
second lien notes for redemption will be made by the Trustee in compliance with
the requirements of the principal national securities exchange, if any, on which
the second lien notes are listed or, if the second lien 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 deems fair and appropriate. The Issuers will not
redeem second lien notes in principal amounts of less than $1,000. In addition,
if a partial redemption is made with the proceeds of an Equity Offering,
selection of second lien 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 The Depository Trust Company), unless
such method is otherwise prohibited. The Issuers will mail notice of redemption
at least 30 and not more than 60 days before the redemption date. The notice
will describe the amount of second lien notes being redeemed, if less than the
entire principal amount. Interest will cease to accrue on second lien notes
which are redeemed on the redemption date.

                                       75
<PAGE>
Security

    All of the Obligations of the Issuers under the second lien notes and the
indenture are secured by a second priority Lien, but subject to Permitted Liens,
on substantially all of the Oil and Gas Assets of the Issuers and the Subsidiary
Guarantors, and by a second priority Lien, subject to Permitted Liens, on
substantially all of any Oil and Gas Assets acquired thereafter (other than
assets securing Acquired Indebtedness to the extent granting additional Liens
would be prohibited by the terms of the instruments relating to such Acquired
Indebtedness), as well as the Capital Stock of Grey Wolf owned by the Issuers,
such Lien being junior to the Liens securing the First Lien Notes. The Oil and
Gas Assets that initially secure such Obligations represent approximately 99% of
the PV-10 value at December 31, 1998.

    If the second lien notes become due and payable prior to maturity or are not
paid in full at maturity, the Trustee may take all actions it deems necessary or
appropriate, including, but not limited to, foreclosing upon the Collateral in
accordance with the security documents and applicable law. The right to
foreclose on the Collateral is, however, subject to a 180-day standstill period
in favor of the holders of the First Lien Notes described below. Subject to the
right of the holders of the First Lien Notes, the proceeds received from the
sale of any Collateral that is the subject of a foreclosure or collection suit
will be applied first to pay the expenses of such foreclosure or suit and
amounts then payable to the Trustee and thereafter to pay the principal of and
interest on the second lien notes. The Trustee has the power to institute and
maintain such suits and proceedings as it may deem expedient to prevent
impairment of, or to preserve or protect its and the holders' interest in, the
Collateral.


    If an Event of Default has occurred, the Trustee or a holder, as the case
may be, must give the First Lien Notes Representative written notice prior to
taking action to enforce its foreclosure rights with respect to any of the
Collateral in connection with such Event of Default, with such notice stating
that an Event of Default has occurred under the indenture and stating that such
notice is being given to commence a Standstill Period. The Trustee and such
holder will not be allowed to take a foreclosure action with respect to such
Event of Default until 180 days have elapsed since the date the notice is given
by the Trustee or the holder to the First Lien Notes Representative, unless the
First Lien Notes Representative consents to the taking of the foreclosure
action. The First Lien Notes Representative has the authority to give such
consent on behalf of the holders of the First Lien Notes pursuant to the First
Lien Indenture. The foregoing provisions of this paragraph will cease to be
applicable upon the payment in full of all Indebtedness under the First Lien
Notes and the First Lien Indenture.

    We cannot assure you that the Trustee will be able to sell the Collateral
without substantial delays or compromises in addition to the 180-day standstill
or that the proceeds obtained will be sufficient to pay all amounts owing to
holders of the second lien notes. You should read the discussion under the
heading "Risk Factors --The security for the second lien notes may be inadequate
to satisfy all amounts due and owing under the first lien notes and the second
lien notes" for a further discussion regarding the adequacy of the collateral
securing the second lien notes. Third parties that have Permitted Liens
(including, without limitation, the holders of the First Lien Notes) may have
rights and remedies with respect to the property subject to such Liens that, if
exercised, could adversely affect the value of the Collateral. In addition, the
ability of the holders to realize upon the Collateral may be subject to certain
bankruptcy law limitations in the event of a bankruptcy. You should read the
discussion under the heading "Risk Factors" For more information regarding these
bankruptcy law limitations.


    The collateral release provisions of the indenture will permit the release
of Collateral without substitution of collateral of equal value under certain
circumstances. See "Possession, Use and Release of Collateral." As described
under the summary of the covenant "Limitation on Asset Sales," the Net Cash
Proceeds of certain Asset Sales may under specified circumstances be required to
be utilized to make an offer to purchase second lien notes.

                                       76
<PAGE>
Change of Control

    If a Change of Control occurs, each holder will have the right to require
that the Issuers purchase all or a portion of such holder's second lien 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, to the date of purchase.

    The Issuers must mail a notice of any Change of Control to each holder and
the Trustee no later than 30 days after the Change of Control occurs. The notice
will 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 must remain open for a period of 20 Business Days or such longer
period as may be required by law. Holders electing to have a second lien note
purchased pursuant to a Change of Control Offer will be required to surrender
the second lien note, with the form entitled "Option of Holder to Elect
Purchase" on the reverse of the second lien note completed, to the paying agent
for the second lien 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 will not be required to make a Change of Control Offer 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 the
second lien 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 second lien notes that might be delivered by holders
seeking to accept the Change of Control Offer. In addition, the First Lien Notes
Indenture and the 11 1/2% Senior Notes due 2004, Series D indenture have
substantially identical change of control provisions as the indenture, which may
further restrict the ability of the Issuers to purchase the second lien notes.
In the event the Issuers are required to purchase second lien 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 Abraxas nor the Trustee may waive the
covenant relating to the Issuers' obligation to make a Change of Control Offer.
Restrictions in the indenture described in this Description of the Second Lien
Notes on the ability of the Issuers and their 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 Issuers, whether favored or opposed by the management of the
Issuers. Consummation of any such transaction in certain circumstances may
require repurchase of the second lien notes, and there can be no assurance that
the Issuers 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 Issuers by the management of the Issuers. 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 second lien 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 second lien notes pursuant to a Change of Control Offer. These
rules require that the Issuers keep the offer open for 20 Business Days. They
also require that the Issuers notify holders of second lien notes of changes in
the offer and extend the offer for specified time periods if we amend the offer.
If the provisions of any securities laws or regulations conflict with the
"Change of Control" provisions in the indenture, the Issuers will comply with
the applicable securities laws and regulations and will not be deemed to have
breached their obligations under the "Change of Control" provisions of the
indenture.

Certain Covenants

    The indenture contains, among others, the following covenants:

                                       77
<PAGE>
Limitation on Incurrence of Additional Indebtedness

    Other than the Permitted Indebtedness, Abraxas may not, and may 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. However, 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 Issuers and the Subsidiary Guarantors or any of
them may incur Indebtedness (including any Acquired Indebtedness), in each case,
if at the time of such event and after giving effect thereto on a pro forma
basis, both:

    o   Abraxas' Consolidated EBITDA Coverage Ratio would have been at least
        equal to 2.5 to 1.0; and

    o   Abraxas' Adjusted Consolidated Net Tangible Assets are equal to or
        greater than 150% of the aggregate consolidated Indebtedness of Abraxas
        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
the amount of Indebtedness 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 Abraxas or any Restricted
Subsidiary or which is secured by a Lien on an asset acquired by Abraxas 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.

    The Issuers 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 such Issuer 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 second lien 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 such Issuer or such Subsidiary
Guarantor, as the case may be.

Limitation on Restricted Payments

    The indenture defines the following as Restricted Payments if done by
Abraxas or any of its Restricted Subsidiaries:

    o   declare or pay any dividend or make any distribution (other than
        dividends or distributions payable solely in Qualified Capital Stock of
        Abraxas) on or in respect of shares of Abraxas' Capital Stock to holders
        of such Capital Stock;

    o   purchase, redeem or otherwise acquire or retire for value any Capital
        Stock of Abraxas 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 Abraxas or
        warrants, rights or options to purchase or acquire shares of Qualified
        Capital Stock of Abraxas;

    o   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 Subordinated Indebtedness of an Issuer or a Subsidiary
        Guarantor; or

    o   make any Investment (other than a Permitted Investment).

The Issuers may not make a Restricted Payment, if at the time of such Restricted
Payment or immediately after giving effect to the Restricted Payment:

                                       78
<PAGE>
    o   a Default or an Event of Default shall have occurred and be continuing;

    o   Abraxas is not able to incur at least $1.00 of additional Indebtedness
        (other than Permitted Indebtedness) in compliance with the covenant
        described under "Limitation on Incurrence of Additional Indebtedness"
        above; or

    o   the aggregate amount of all 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 Abraxas) shall exceed the sum of:

                 (i) 50% of the cumulative Consolidated Net Income (or if
             cumulative Consolidated Net Income shall be a loss, minus 100% of
             such loss) of Abraxas earned subsequent to the Issue Date and on or
             prior to the last date of Abraxas' fiscal quarter immediately
             preceding such Restricted Payment (the "Reference Date") (treating
             such period as a single accounting period), plus

                 (ii) 100% of the aggregate net cash proceeds received by
             Abraxas from any Person (other than a Restricted Subsidiary of
             Abraxas) from the issuance and sale subsequent to the Issue Date
             and on or prior to the Reference Date of Qualified Capital Stock of
             Abraxas, plus

                 (iii) without duplication of any amounts included in clause(ii)
             above, 100% of the aggregate net cash proceeds of any equity
             contribution received by Abraxas from a holder of Abraxas' Capital
             Stock (excluding, in the case of clauses (ii) and (iii), any net
             cash proceeds from an Equity Offering to the extent used to redeem
             the second lien notes), plus

                 (iv) 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 Abraxas or to any Restricted Subsidiary of
             Abraxas from Unrestricted Subsidiaries (but without duplication of
             any such amount included in calculating cumulative Consolidated Net
             Income of Abraxas), or from redesignations of Unrestricted
             Subsidiaries as Restricted Subsidiaries (in each case valued as
             provided in the covenant described under "Limitation on Designation
             of Unrestricted Subsidiaries" below), not to exceed, in the case of
             any Unrestricted Subsidiary, the amount of Investments previously
             made by Abraxas or any Restricted Subsidiary in such Unrestricted
             Subsidiary and which was treated as a Restricted Payment under the
             indenture, plus

                 (v) without duplication of the immediately preceding subclause
             (iv), 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
             Abraxas).

    However, the Issuers may take the following actions:

    o   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,

    o   if no Default or Event of Default shall have occurred and be continuing,
        the acquisition of any shares of Capital Stock of Abraxas, either:

             (A) solely in exchange for shares of Qualified Capital Stock of
        Abraxas, or

             (B) through the application of net proceeds of a substantially
        concurrent sale for cash (other than to a Restricted Subsidiary of
        Abraxas) of shares of Qualified Capital Stock of Abraxas,

                                       79
<PAGE>
    o   if no Default or Event of Default shall have occurred and be continuing,
        the acquisition of any Indebtedness of Abraxas or a Subsidiary Guarantor
        that is subordinate or junior in right of payment to the second lien
        notes or such Subsidiary Guarantor's Guarantee, as the case may be,
        either:

             (A) solely in exchange for shares of Qualified Capital Stock of
        Abraxas, or

             (B) through the application of net proceeds of a substantially
        concurrent sale for cash (other than to a Restricted Subsidiary of
        Abraxas) of (I) shares of Qualified Capital Stock of Abraxas or (II)
        Refinancing Indebtedness; and

    o   the initial designation of Western Associated Energy Corporation and
        Grey Wolf as Unrestricted Subsidiaries under the indenture.

    In determining the aggregate amount of Restricted Payments made subsequent
to the Issue Date, amounts expended for the payment of any dividend or
redemption payment, as described above, and for the acquisition of any shares of
Capital Stock of Abraxas through the application of net proceeds of a
substantially concurrent sale for cash (other than to a Restricted Subsidiary of
Abraxas) of shares of Qualified Capital Stock of Abraxas, as described above,
shall be included in such calculation.

Limitation on Asset Sales

    Abraxas may not, and may not cause or permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless the consideration received is
at least equal to the fair market value of the assets sold or otherwise disposed
of, as determined in good faith by Abraxas' Board of Directors or senior
management of Abraxas, and at least 75% of the consideration received is cash or
Cash Equivalents and is received at the time of such disposition.

    Within 180 days after the receipt of any Net Cash Proceeds from an Asset
Sale plus such additional time as may be necessary to complete a net proceeds
offer under the terms of the First Lien Indenture with respect to such Asset
Sale ("Net Cash Proceeds Application Period"), Abraxas or such Restricted
Subsidiary must apply the Net Cash Proceeds of such Asset Sale as follows:

    o   to the extent such Net Cash Proceeds are received from an Asset Sale not
        involving the sale, transfer or disposition of Collateral
        ("Non-Collateral Proceeds"), to repay any Indebtedness secured by the
        assets involved in such Asset Sale together with a concomitant permanent
        reduction in the amount of such Indebtedness so repaid; and

    o   with respect to any Non-Collateral Proceeds remaining after application
        pursuant to the preceding paragraph and any Net Cash Proceeds received
        from an Asset Sale involving Collateral, Abraxas must make an offer to
        purchase (the "Net Proceeds Offer") from all holders up to a maximum
        principal amount (expressed as an integral multiple of $1,000) of second
        lien notes equal to the Available Proceeds Amount at a purchase price
        equal to 100% of the principal amount thereof plus accrued and unpaid
        interest thereon to the date of purchase.

    Abraxas will not, however, be required to apply Net Cash Proceeds received
from any Asset Sale to make a Net Proceeds Offer if, and only to the extent that
such Net Cash Proceeds are applied, within the Net Cash Proceeds Application
Period for such Asset Sale:

    o   to repay or prepay any Indebtedness outstanding under the First Lien
        Notes or the First Lien Indenture;

    o   to repay or prepay any Indebtedness of Abraxas that is secured by a Lien
        permitted to be incurred pursuant to the section "Covenants--Limitation
        on Liens";

    o   to pay interest on the second lien notes in an aggregate amount not to
        exceed 5.75% of the aggregate original principal amount of the second
        lien notes;

                                       80
<PAGE>
    o   to an investment or investments in Crude Oil and Natural Gas Related
        Assets; or

    o   to an investment or investments 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 Crude Oil and Natural Gas
        Business of Abraxas and its Restricted Subsidiaries ("Replacement
        Assets"), with the properties or assets constituting such Crude Oil and
        Natural Gas Related Assets or Replacement Assets and any non-cash
        consideration received being made subject to the Lien of the indenture
        and the security documents to the extent the Net Cash Proceeds used to
        purchase such properties or assets arose from the sale of properties or
        assets that were subject to such Lien, provided that any such properties
        or assets that are Oil and Gas Assets shall be made subject to such Lien
        in any event.

    In addition, if at the end of the Net Cash Proceeds Application Period for
such Asset Sale, Abraxas or one of its Restricted Subsidiaries has delivered to
the Trustee an officer's certificate:

    o   otherwise in compliance with the terms of the indenture;

    o   stating that attached thereto is a definitive, executed purchase and
        sale agreement for a Crude Oil and Natural Gas Related Assets investment
        or for Replacement Assets; and

    o   setting forth the aggregate cash consideration to be paid in connection
        with such purchase from the Available Proceeds Amount;

then Abraxas shall have an additional period of time during which it may defer
making a Net Proceeds Offer with respect to the Available Proceeds Amount the
subject of such purchase and sale, such additional period of time ending on the
earlier of:

    o   90 days after the end of the Net Cash Proceeds Application Period, and

    o   the date such purchase and sale agreement is terminated or cancelled.

    If at any time any consideration (other than cash or Cash Equivalents)
received in connection with any Asset Sale is converted into or sold or
otherwise disposed of for cash, then such conversion or disposition shall be
treated like an Asset Sale and the Net Cash Proceeds will be applied as
described above.

    Abraxas may defer the Net Proceeds Offer until there is an aggregate
unutilized Available Proceeds Amount equal to or in excess of $5,000,000
resulting from one or more Asset Sales (at which time the entire unutilized
Available Proceeds Amount, and not just the amount in excess of $5,000,000, will
be applied as required pursuant to this paragraph). If the amount of second lien
notes tendered is less than the amount of second lien notes that the Issuers
offered to purchase, Abraxas may obtain a release of the unutilized portion of
the Collateral Proceeds from the Lien of the indenture and the security
documents.

    Notwithstanding the terms of the six preceding paragraphs above, Abraxas and
its Restricted Subsidiaries will be permitted to consummate an Asset Sale
without complying with such paragraphs to the extent:

    o   the consideration for such Asset Sale constitutes Replacement Assets
        and/or Crude Oil and Natural Gas Related Assets; and

    o   such Asset Sale is for fair market value.

Any consideration not constituting  Replacement Assets and Crude Oil and Natural
Gas Related Assets received by Abraxas or any of its Restricted  Subsidiaries in
connection with any Asset Sale permitted to be consummated under this paragraph
will be treated  as Net Cash  Proceeds  and,  to the  extent  that the  property
transferred or conveyed  constitutes an Oil and Gas Asset, the property received
in exchange will constitute an Oil and Gas Asset.

                                       81
<PAGE>
    All Collateral Proceeds delivered to the Trustee will constitute Trust
Moneys, and all Collateral Proceeds will be delivered by Abraxas:

    o   so long as any Indebtedness under the First Lien Notes remains
        outstanding, to the First Lien Notes Representative; and

    o   otherwise to the Trustee and all Collateral Proceeds delivered to the
        Trustee will be deposited in the Collateral Account in accordance with
        the indenture. These Collateral Proceeds may be withdrawn from the
        Collateral Account for application by Abraxas as set forth above or
        otherwise pursuant to the indenture as summarized in "Deposit; Use and
        Release of Trust Moneys."

    In the event of the transfer of substantially all (but not all) of the
consolidated assets of Abraxas as an entirety to a Person in a transaction
permitted under the covenant described in "Merger, Consolidation and Sale of
Assets," the successor corporation will be deemed to have sold the consolidated
assets of Abraxas not so transferred and must comply with the provisions of this
covenant as if it were an Asset Sale. In addition, the fair market value of the
consolidated assets of Abraxas deemed to be sold will be deemed to be Net Cash
Proceeds.

    The Issuers will be required to mail notice of a Net Proceeds Offer to the
holders and the Trustee not less than 30 days nor more than 60 days before the
payment date for the Net Proceeds Offer, 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 second lien notes in whole or in part in
integral multiples of $1,000 principal amount in exchange for cash. To the
extent holders properly tender second lien notes in an amount exceeding the
Available Proceeds Amount, second lien notes will be repurchased on a pro rata
basis (based on amounts tendered).

    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 second lien notes as a result of a Net Proceeds Offer. These rules
require that the Issuers keep the offer open for 20 Business Days. They also
require that the Issuers notify holders of second lien notes of changes in the
offer and extend the offer for specified time periods if the Issuers amend the
offer. If the provisions of any securities laws or regulations conflict with the
"Asset Sale" provisions of the indenture, the Issuers will comply with the
applicable securities laws and regulations and shall not be deemed to have
breached their obligations under the "Asset Sale" provisions of the indenture.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries

    Abraxas may not, and may 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 (each, a "Payment
Restriction") on the ability of any Restricted Subsidiary to:

    o   pay dividends or make any other distributions on or in respect of its
        Capital Stock;

    o   make loans or advances, or to pay any Indebtedness or other obligation
        owed, to Abraxas or any other Restricted Subsidiary;

    o   guarantee any Indebtedness or any other obligation of Abraxas or any
        Restricted Subsidiary; or

    o   transfer any of its property or assets to Abraxas or any other
        Restricted Subsidiary.

    The preceding will not apply, however, to encumbrances or restrictions
existing under or by reason of the following (which are excluded from the term
"Payment Restriction"):

        (1) applicable law;

                                       82
<PAGE>
        (2) the indenture, the indenture governing the old notes, the indenture
    governing the First Lien Notes, any security document or any of the security
    documents entered into in connection with the indenture governing the old
    notes or the indenture governing the First Lien Notes;

        (3) customary non-assignment provisions of any contract or any lease
    governing a leasehold interest of any Restricted Subsidiary;

        (4) 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;

        (5) agreements existing on the Issue Date to the extent and in the
    manner such agreements were in effect on the Issue Date;

        (6) customary restrictions with respect to a Restricted Subsidiary
    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;

        (7) 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

        (8) an agreement governing Refinancing Indebtedness incurred to
    Refinance the Indebtedness issued, assumed or incurred pursuant to an
    agreement referred to in clause (2), (4) or (5) 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 Abraxas in
    its reasonable and good faith judgment than the provisions relating to such
    encumbrance or restriction contained in the applicable agreement referred to
    in such clause (2), (4) or (5).

Limitation on Preferred Stock of Restricted Subsidiaries

    The Restricted Subsidiaries may not issue any Preferred Stock (other than to
Abraxas or to a Wholly Owned Restricted Subsidiary) or permit any Person (other
than Abraxas or a Wholly Owned Restricted Subsidiary) to own any Preferred Stock
of any Restricted Subsidiary.

Limitation on Liens

    Abraxas may not, and may not cause or permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or permit or
suffer to exist or remain in effect any Liens:

    o   upon any item of Collateral other than the Liens created by the
        indenture and the security documents and the Liens expressly permitted
        by the applicable security documents, and any Liens securing the First
        Lien Notes or any other Indebtedness under the First Lien Indenture;

    o   upon any other properties or assets of Abraxas or of any of its
        Restricted Subsidiaries, whether owned on the Issue Date or acquired
        after the Issue Date, or on any income or profits therefrom, or assign
        or otherwise convey any right to receive income or profits thereon other
        than, with respect to this clause:

              (i) Liens existing on the Issue Date to the extent and in the
        manner such Liens are in effect on the Issue Date,

              (ii) Permitted Liens, and

              (iii) any Liens securing the First Lien Notes or any other
        Indebtedness under the First Lien Indenture.

                                       83
<PAGE>

Merger, Consolidation and Sale of Assets

    Abraxas may 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 Abraxas'  assets  (determined on a consolidated  basis for
Abraxas   and  its   Restricted   Subsidiaries),   whether  as  an  entirety  or
substantially as an entirety to any Person unless:

    o   either

              (A) Abraxas or such Restricted Subsidiary, as the case may be,
        shall be the surviving or continuing corporation or

              (B) the Person (if other than Abraxas) formed by such
        consolidation or into which Abraxas is merged or the Person which
        acquires by sale, assignment, transfer, lease, conveyance or other
        disposition the assets of Abraxas and its Restricted Subsidiaries
        substantially as an entirety (the "Surviving Entity")

                 (i) 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

                 (ii) 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 second lien notes and the performance
        of every covenant of the second lien notes, the indenture, and the
        security documents on the part of Abraxas to be performed or observed;

    o   immediately after giving effect to such transaction and the assumption
        contemplated above (including giving effect to any Indebtedness incurred
        or anticipated to be incurred and any Lien granted in connection with or
        in respect of such transaction), Abraxas or such Surviving Entity, as
        the case may be,

            (A) shall have a Consolidated Net Worth equal to or greater than the
        Consolidated Net Worth of Abraxas immediately prior to such transaction
        and

            (B) shall be able to incur at least $1.00 of additional Indebtedness
        (other than Permitted Indebtedness) pursuant to the covenant described
        in "Limitation on Incurrence of Additional Indebtedness";

    o   immediately before and immediately after giving effect to such
        transaction and the assumption contemplated 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

    o   Abraxas or the Surviving Entity, as the case may be, shall have
        delivered to the Trustee an officer's 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.

    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 assets of one or more Restricted Subsidiaries the
Capital Stock of which constitutes all or substantially all of the assets of
Abraxas, shall be deemed to be the transfer of all or substantially all of the
assets of Abraxas.

    Upon any consolidation or merger or any transfer of all or substantially all
of the assets of Abraxas in accordance with the foregoing, in which Abraxas is
not the continuing corporation, the successor Person formed by such
consolidation or into which Abraxas is merged or to which such transfer is made
shall succeed to, and be substituted for, and may exercise every right and power
of, Abraxas under the indenture and the second lien notes and thereafter (except
in the case of a lease), Abraxas will be relieved of all further obligations and
covenants under the indenture and the second lien notes.

    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") may
not, and Abraxas may not cause or permit any Subsidiary Guarantor to,
consolidate with or merge with or into any Person other than an Issuer or
another Subsidiary Guarantor that is a Wholly Owned Restricted Subsidiary
unless:

    o   the entity formed by or surviving any such consolidation or merger (if
        other than the Subsidiary Guarantor) is a corporation organized and
        existing under the laws of the United States or any state thereof or the
        District of Columbia (or if such Restricted Subsidiary was formed under
        the laws of Canada or any province or territory thereof, such Surviving
        Entity shall be a corporation organized and validly existing under the
        laws of Canada or any province or territory thereof);

    o   such entity assumes by execution of a supplemental indenture all of the
        obligations of the Subsidiary Guarantor under its Guarantee;

    o   immediately after giving effect to such transaction, no Default or Event
        of Default shall have occurred and be continuing; and

    o   immediately after giving effect to such transaction and the use of any
        net proceeds therefrom on a pro forma basis, Abraxas could satisfy the
        Consolidated Net Worth and incurrence of Additional Indebtedness
        provisions set forth above.

Any merger or  consolidation  of a Subsidiary  Guarantor with and into either of
the Issuers (with either of the Issuers  being the Surviving  Entity) or another
Subsidiary  Guarantor  that is a Wholly Owned  Restricted  Subsidiary  need only
comply with the officer's certificate and opinion of counsel provisions set
forth above.

Limitations on Transactions with Affiliates

     Abraxas may not, and may not permit any of its Restricted Subsidiaries to,
directly or indirectly, engage in 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 any of their respective Affiliates unless,

    o   such transaction or series of related transactions is on terms that are
        fair and reasonable to Abraxas or the applicable Restricted Subsidiary
        and are no less favorable to Abraxas or the applicable Restricted
        Subsidiary than would have been obtained in a comparable transaction at
        such time on an arm's-length basis from a Person that is not an
        Affiliate ; and

    o   with respect to a transaction or series of related transactions
        involving aggregate payments or other property with a fair market value
        in excess of $1,000,000, Abraxas obtains Board approval which is
        evidenced by a resolution stating that the Board has determined that
        such transaction complies with the foregoing provisions.

In addition,  if the transaction or series of related  transactions  involves an
aggregate fair market value of more than $10,000,000, Abraxas must, prior to the
consummation thereof, obtain a favorable opinion as to the fairness of such
transaction  or  series of  related  transactions  to  Abraxas  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.

     The foregoing shall not apply to

    o   reasonable fees and compensation paid to and indemnity provided on
        behalf of, officers, directors, employees or consultants of Abraxas or
        any Restricted Subsidiary as determined in good faith by the Board of
        Directors or senior management of Abraxas or such Restricted Subsidiary,
        as the case may be;

                                       85
<PAGE>
    o   transactions exclusively between or among Abraxas and any of its
        Restricted Subsidiaries or exclusively between or among such Restricted
        Subsidiaries if such transactions are not otherwise prohibited by the
        indenture; and

    o   Restricted Payments permitted by the indenture.

Limitation on Restricted and Unrestricted Subsidiaries

    The indenture provides that the Board of Directors of Abraxas 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

    o   any such redesignation shall be deemed to be an incurrence by Abraxas
        and its Restricted Subsidiaries of the Indebtedness (if any) of such
        redesignated Subsidiary under the covenant described in "Limitation on
        Incurrence of Additional Indebtedness" above;

    o   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, Abraxas could not incur $1.00 of additional
        Indebtedness (other than Permitted Indebtedness) under the covenant
        described in "Limitation on Incurrence of Additional Indebtedness"
        above; and

    o   such Subsidiary assumes all of the obligations of a Subsidiary Guarantor
        under a Guarantee.

     The Board of Directors of Abraxas also may, if no Default or Event of
Default shall have occurred and be continuing or would arise from such a
designation, designate any Restricted Subsidiary none of whose Properties are
subject to any Liens of any security documents to be an Unrestricted Subsidiary
if:

    o   such designation is at that time permitted under the covenant described
        in "Limitation on Restricted Payments" above; and

    o   immediately after giving effect to such designation, Abraxas could incur
        $1.00 of additional Indebtedness (other than Permitted Indebtedness)
        pursuant to the covenant described in "Limitation on Incurrence of
        Additional Indebtedness" above.

     Any such designation by such 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
officer's 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.

     For purposes of the covenant described under "Limitation on Restricted
Payments" above,

    o   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 Abraxas' 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;

    o   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 Abraxas' 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


                                       86
<PAGE>
        Investments previously made by Abraxas and its Restricted Subsidiaries
        in such Unrestricted Subsidiary with, "net worth" calculated based upon
        the fair market value of the assets of such Subsidiary as of any such
        date of designation); and

    o   any property transferred to or from an Unrestricted Subsidiary shall be
        valued at its fair market value at the time of such transfer.

    Notwithstanding the foregoing, such Board of Directors may not designate any
Subsidiary of Abraxas to be an Unrestricted Subsidiary if, after such
designation,

    o   Abraxas or any Restricted Subsidiary

             (A) provides credit support for, or a guarantee of, any
         Indebtedness of such Subsidiary (including any undertaking, agreement
         or instrument evidencing such Indebtedness) or

             (B) is directly or indirectly liable for any Indebtedness of such
         Subsidiary, or

    o   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 Subsidiaries of Abraxas that are not designated by the Board of
Directors as Restricted or Unrestricted Subsidiaries will be deemed to be
Restricted Subsidiaries. All Subsidiaries of an Unrestricted Subsidiary will be
Unrestricted Subsidiaries.

Additional Subsidiary Guarantees

    If Abraxas 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
Abraxas 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

    o   execute and deliver to the Trustee a Guarantee in form reasonably
        satisfactory to the Trustee pursuant to which such Restricted Subsidiary
        shall unconditionally guarantee all of the Issuers' obligations under
        the second lien notes and the indenture on the terms set forth in the
        indenture;

    o   grant to the Trustee a second Lien on substantially all its Oil and Gas
        Assets; and

    o   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 Impairment of Security Interest

    Neither Abraxas nor any of its Subsidiaries may take or omit to take any
action which would have the result of adversely affecting or impairing the
security interest in favor of the Trustee, on behalf of itself and the holders,
with respect to the Collateral, and neither Abraxas nor any of its Subsidiaries
may grant to any Person, or suffer any Person (other than Abraxas and its
Restricted Subsidiaries) to have (other than to the Trustee on behalf of the
Trustee and the holders) any interest whatsoever in the Collateral other than
Permitted Liens. Neither Abraxas nor any of its Subsidiaries may enter into any
agreement or instrument that by its terms requires the proceeds received from
any sale of Collateral to be applied to repay, redeem, defease or otherwise
acquire or retire any Indebtedness, other than Indebtedness under the First Lien
Notes or under the First Lien Indenture and the security documents entered into
in connection therewith, and other than pursuant to the indenture and the
security documents.

                                       87
<PAGE>
Limitation on the Sale or Issuance of Capital Stock of Restricted Subsidiaries

    Abraxas may not, and may not permit any Restricted Subsidiary to, sell or
otherwise dispose of any shares of Capital Stock of any Restricted Subsidiary,
and shall not permit any of its Restricted Subsidiaries, directly or indirectly,
to issue or sell or otherwise dispose of any of its Capital Stock except:

    o   to Abraxas or a Wholly Owned Restricted Subsidiary of Abraxas; or

    o   if all shares of Capital Stock of such Restricted Subsidiary owned by
        Abraxas and its Restricted Subsidiary are sold or otherwise disposed of.

    In connection with any sale or disposition of Capital Stock of any
Restricted Subsidiary, Abraxas will be required to comply with the covenant
described under the caption "Limitation on Asset Sales."

Limitation on Conduct of Business

    Abraxas 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

    Abraxas will deliver to the Trustee within 15 days after the filing of the
same with the SEC, copies of the quarterly and annual reports and of the
information, documents and other reports, if any, which Abraxas is required to
file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.
Notwithstanding that Abraxas may not be subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, Abraxas will file with the SEC, 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. Abraxas will also comply with the other provisions of
Section 314(a) of the TIA.

Events of Default

       Each of the following is an Event of Default:

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

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

    o   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 of the Issuers or any Subsidiary
        Guarantor 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 second lien notes
        (except in the case of a default with respect to observance or
        performance of any of the terms or provisions of the covenants described
        above under "Change of Control" or "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);

    o   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 Abraxas or of any Restricted Subsidiary (or the payment
        of which is guaranteed by Abraxas or any Restricted Subsidiary), whether
        such Indebtedness now exists or is created after the Issue Date, which
        default:

                                       88
<PAGE>
                 (A) 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

                 (B) 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;

    o   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) are rendered against Abraxas 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;

    o   certain events of bankruptcy; or

    o   any of the Guarantees or any of the security documents cease to be in
        full force and effect or any of the Guarantees or any of the security
        documents 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) or any obligor
        or any Related Person denies or disaffirms its liability under any
        security document to which it is a party.

    If any Event of Default (other than the Event of Default relating to certain
events of bankruptcy) occurs and is continuing, the Trustee or the holders of at
least 25% in principal amount of outstanding second lien notes may declare the
principal of, premium, if any, and accrued and unpaid interest on all the second
lien 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 relating to certain events of bankruptcy occurs and is
continuing, then all unpaid principal of, and premium, if any, and accrued and
unpaid interest on all of the outstanding second lien notes will be immediately
due and payable without any declaration or other act on the part of the Trustee
or any holder.

    After a declaration of acceleration with respect to the second lien notes as
described  in the  preceding  paragraph,  the holders of a majority in principal
amount of the second lien notes may rescind and cancel such declaration if:

    o   the rescission would not conflict with any judgment or decree;

    o   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;

    o   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;

    o   the Issuers have paid the Trustee its reasonable compensation and
        reimbursed the Trustee for its expenses, disbursements and advances; and

    o   the Trustee shall have received an officer's certificate and an opinion
        of counsel that such Event of Default has been cured or waived in the
        event of the cure or waiver of an Event of Default relating to certain
        events of bankruptcy.

    No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

    Prior to the declaration of acceleration of the second lien notes, the
holders of a majority in principal amount of the second lien 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 second
lien notes.

                                       89
<PAGE>
    Holders of the second lien notes may not enforce the indenture or the second
lien 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 second lien notes will 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.

    The Issuers are required to provide an officer's 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.

Possession, Use and Release of Collateral

    Unless an Event of Default shall have occurred and be continuing, the
Issuers and the Subsidiary Guarantors will have the right to remain in
possession and retain exclusive control of the Collateral securing the second
lien notes (other than any cash, securities, obligations and Cash Equivalents
constituting part of the Collateral and deposited with the Trustee in the
Collateral Account or with the First Lien Notes Representative and other than as
set forth in the security documents), to freely operate the Collateral and to
collect, invest and dispose of any income thereon.

Release of Collateral

    Upon compliance by the Issuers with the conditions set forth below in
respect of any sale, transfer or other disposition, the Trustee will release the
Released Interests (as defined below) from the Lien of the indenture and the
security documents and reconvey the Released Interests to the Issuers or the
grantor of the Lien on such property. The Issuers will have the right to obtain
a release of items of Collateral (the "Released Interests") subject to any sale,
transfer or other disposition, or owned by a Restricted Subsidiary the Capital
Stock of which is sold in compliance with the indenture such that it ceases to
be a Restricted Subsidiary, upon compliance with the condition that the Issuers
deliver to the Trustee the following:

    o   a notice from Abraxas requesting the release of Released Interests:

                 (A) describing the proposed Released Interests,

                 (B) specifying the value of such Released Interests or such
         Capital Stock, as the case may be, on a date within 60 days of the
         Abraxas notice (the "Valuation Date"),

                 (C) stating that the consideration to be received is at least
         equal to the fair market value of the Released Interests,

                 (D) stating that the release of such Released Interests will
         not interfere with the Trustee's ability to realize the value of the
         remaining Collateral and will not impair the maintenance and operation
         of the remaining Collateral,

                 (E) confirming the sale or exchange of, or an agreement to sell
         or exchange, such Released Interests or such Capital Stock, as the case
         may be, is a bona fide sale to or exchange with a Person that is not an
         Affiliate of the Issuers or, in the event that such sale or exchange is
         to or with a Person that is an Affiliate, confirming that such sale or
         exchange is made in compliance with the provisions summarized in the
         description of certain covenants under "Limitation on Transactions with
         Affiliates," and

                                       90
<PAGE>

                 (F) in the event there is to be a contemporaneous substitution
         of property for the Collateral subject to the sale, transfer or other
         disposition, specifying the property intended to be substituted for the
         Collateral to be disposed of;

    o   an officer's certificate of Abraxas stating that:

                 (A) such sale, transfer or other disposition complies with the
         terms and conditions of the indenture, including the provisions
         summarized in the description of certain covenants under " Limitation
         on Asset Sales," "Limitation on Transactions with Affiliates,"
         "Limitation on Restricted and Unrestricted Subsidiaries" and
         "Limitation on Restricted Payments" above, to the extent any of the
         foregoing are applicable,

                 (B) all Net Cash Proceeds from the sale, transfer or other
         disposition of any of the Released Interests or such Capital Stock, as
         the case may be, will be applied pursuant to the provisions of the
         indenture in respect of the deposit of proceeds into the Collateral
         Account or with the First Lien Notes Representative as contemplated by
         the indenture and in respect of Asset Sales, to the extent applicable,

                 (C) there is no Default or Event of Default in effect or
         continuing on the date thereof or the date of such sale, transfer or
         other disposition,

                 (D) the release of the Collateral will not result in a Default
         or Event of Default under the indenture,

                 (E) upon delivery of such officer's certificate, all conditions
         precedent in the indenture relating to the release in question will
         have been complied with,

                 (F) such sale, transfer or other disposition is not between
         Abraxas or any Restricted Subsidiary or between Restricted
         Subsidiaries, and

                 (G) such sale, transfer or other disposition is not a sale,
         transfer or other disposition that is excluded from the definition of
         "Asset Sale" because it was a sale, lease, conveyance, disposition or
         other transfer of all or substantially all of the assets of Abraxas in
         a transaction which made in compliance with the provisions of the
         covenants described under "Merger, Consolidation and Sale of Assets;"
         and

    o   all documentation required by the TIA, if any, prior to the release of
        Collateral by the Trustee and, in the event there is to be a
        contemporaneous substitution of property for the Collateral subject to
        such sale, transfer or other disposition, all documentation necessary to
        effect the substitution of such new Collateral.

    Notwithstanding the provisions described above, so long as no Event of
Default shall have occurred and be continuing, the Issuers may, without
satisfaction of the conditions described above, dispose of Hydrocarbons or other
mineral products for value in the ordinary course and engage in any number of
ordinary course activities in respect of the Collateral, in limited dollar
amounts specified by the TIA, upon satisfaction of certain conditions. For
example, among other things, subject to certain dollar limitations and
conditions, the Issuers would be permitted to:

    o   sell or otherwise dispose of any property subject to the Lien of the
        indenture and the security documents, which may have become worn out or
        obsolete;

Deposit; Use and Release of Trust Moneys

    The Net Cash Proceeds associated with any Asset Sale and any Net Cash
Proceeds associated with any sale, transfer or other disposition of Collateral,
to the extent such sale, transfer or other disposition is not an Asset Sale by
virtue of clause (H) of the definition thereof, insurance proceeds and
condemnation (or similar) proceeds shall be deposited so long as any
Indebtedness under the First Lien Notes remains outstanding, with the First Lien
Notes Representative and otherwise into a securities account maintained by the
Trustee at its corporate trust offices or at any securities intermediary
selected by the Trustee having a combined capital and surplus of at least
$250,000,000 and having a long-term debt rating of at least "A3" by Moody's and
at least "A--" by S&P styled the "Abraxas Collateral Account" (such account
being the "Collateral Account") which shall be under the exclusive dominion and
control of the Trustee. All amounts on deposit in the Collateral Account shall
be treated as financial assets and cash funds on deposit in the Collateral
Account may be invested by the Trustee, at the direction of the Issuers, in Cash
Equivalents. The Issuers will not have the right to withdraw funds or assets
from the Collateral Account except in compliance with the terms of the indenture
and all assets credited to the Collateral Account shall be subject to a Lien in
favor of the Trustee and the holders.

    Any funds deposited with the Trustee may be released to the Issuers by their

    o   no Event of Default has occurred and is continuing as of the date of the
        proposed release;

                 (A) if such Trust Moneys represent Collateral Proceeds in
         respect of an Asset Sale, that such funds are otherwise being applied
         in accordance with the covenant "Limitation on Asset Sales," above, or

                 (B) if such Trust Moneys represent proceeds in respect of a
         casualty, expropriation or taking, such funds will be applied to repair
         or replace property subject of a casualty or condemnation or reimburse
         the Issuers for amounts spent to repair or replace such property and
         that attached thereto are invoices or other evidence reflecting the
         amounts spent or to be spent, or

                 (C) if such Trust Moneys represent proceeds derived from any
         other manner, that such amounts are being utilized in connection with
         business of Abraxas and its Restricted Subsidiaries in compliance with
         the terms of the indenture; and

    o   all conditions precedent in the indenture relating to the release in
        question have been complied with; and

    o   all documentation required by the TIA, if any, prior to the release of
        such Trust Moneys by the Trustee has been delivered to the Trustee.

    Notwithstanding the foregoing,

    o   if the maturity of the second lien notes has been accelerated, and the
        acceleration has not been rescinded as permitted by the indenture, the
        Trustee shall apply the Trust Moneys credited to the Collateral Account
        to pay the principal of, premium, if any and accrued and unpaid interest
        on the second lien notes to the extent of such Trust Moneys;

    o   if the Issuers so elect, by giving written notice to the Trustee, the
        Trustee shall apply Trust Moneys credited to the Collateral Account to
        the payment of interest due on any interest payment date; and

                                       92
<PAGE>
    o   if the Issuers so elect, by giving written notice to the Trustee, the
        Trustee shall apply Trust Moneys credited to the Collateral Account to
        the payment of the principal of, and premium, if any, and accrued and
        unpaid interest on any second lien notes on the maturity or upon
        redemption or to the purchase of second lien notes upon tender or in the
        open market or at private sale or upon any exchange or in any one or
        more of such ways, in each case in compliance with the indenture.

                                       93
<PAGE>
Legal Defeasance and Covenant Defeasance

    As long as the Issuers take steps to make sure that holders receive all of
their payment under the second lien notes and are able to transfer the second
lien notes, the Issuers can elect to legally release themselves and any of the
Subsidiary Guarantors for any Obligations on the second lien notes (called
"Legal Defeasance") other than:

    o  the rights of holders to receive payments in respect of the principal of,
       premium, if any, and interest on the second lien notes when such payments
       are due;

    o  the Issuers' obligations with respect to the second lien notes to issue
       temporary second lien notes, register second lien notes, replace
       mutilated, destroyed, lost or stolen second lien notes and the
       maintenance of an office or agency for payments;

    o  the rights, powers, trust, duties and immunities of the Trustee; and

    o  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 and the Subsidiary Guarantors, if any, released
with respect to certain covenants that are described in the indenture ("Covenant
Defeasance"). 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 second lien notes. The occurrence of either Legal
Defeasance or Covenant Defeasance would result in a release of all Collateral
from the Lien of the indenture and the security documents.

    In order to exercise either Legal Defeasance or Covenant Defeasance,

    o  the Issuers must irrevocably deposit with the Trustee, in trust, for the
       benefit of the holders cash in U.S. dollars and/or non-callable U.S.
       government obligations 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 second lien notes on their various due dates:

    o  in the case of Legal Defeasance, the Issuers must deliver to the Trustee
       an opinion of counsel in the United States reasonably acceptable to the
       Trustee confirming that:

       (A) the Issuers have received from, or there has been published by, the
       Internal Revenue Service a ruling, or

       (B) since the Issue Date, there has been a change in the applicable
       federal income tax law, in either case to the effect 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;

    o  in the case of Covenant Defeasance, the Issuers must deliver 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;

    o  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;

                                       94
<PAGE>
   o  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 Abraxas or any of its Restricted
       Subsidiaries is a party or by which Abraxas or any of its Restricted
       Subsidiaries is bound;

    o  the Issuers must deliver an officer's certificate to the Trustee stating
       that the deposit was not made by the Issuers with the intent of
       preferring the holders over any other creditors of the Issuers or with
       the intent of defeating, hindering, delaying or defrauding any other
       creditors of the Issuers or others;

    o  the Issuers must deliver an officer's certificate and an opinion of
       counsel to the Trustee, 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; and

    o  the Issuers must deliver an opinion of counsel to the Trustee 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. o

Satisfaction and Discharge

    The Issuers and the Subsidiary Guarantors will have no further obligations
under the indenture, the security documents and the Guarantees as to all
outstanding second lien notes, other than surviving rights of registration of
transfer or exchange of the second lien notes, when

    o  either

       (A) all the second lien notes have been delivered to the Trustee for
       cancellation except lost, stolen or destroyed second lien notes which
       have been replaced or paid and second lien notes which the Issuers have
       deposited in trust or segregated and held in trust by the Issuers and
       thereafter repaid to the Issuers or discharged from such trust, or

       (B) all second lien notes have become due and payable and the Issuers
       have deposited with the Trustee funds in sufficient to pay and discharge
       the entire Indebtedness on the second lien notes on their various due
       dates;

    o  the Issuers have paid all other sums payable under the indenture by the
       Issuers; and

    o  the Issuers have delivered to the Trustee an officer's certificate and an
       opinion of counsel stating that the Issuers have complied with all
       conditions precedent under the indenture relating to the satisfaction and
       discharge of the indenture.

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, the second lien
notes, the guarantees or any security document for certain specified purposes,
including curing ambiguities, defects or inconsistencies, to comply with any
requirements of the SEC 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.

    Other modifications and amendments of the indenture or any security document
may be made with the consent of the holders of not less than a majority of the
principal amount of the then outstanding second lien notes issued under the
indenture, except that, without the consent of each holder affected thereby, no
amendment may:

    o  reduce the amount of second lien notes whose holders must consent to an
       amendment;


                                       95
<PAGE>
    o   reduce the rate of or change or have the effect of changing the time for
        payment of interest, including defaulted interest, on any second lien
        notes;

    o   reduce the principal of or change or have the effect of changing the
        fixed maturity of any second lien notes, or change the date on which any
        second lien notes may be subject to redemption or repurchase, or reduce
        the redemption or repurchase price therefor;

    o   make any second lien notes payable in money other than that stated in
        the second lien notes;

    o   make any change in provisions of the indenture or any security document
        protecting the right of each holder to receive payment of principal of
        and interest on such second lien 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 second lien notes to waive Defaults or
        Events of Default;

    o   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;

    o   modify or change any provision of the indenture, any security document
        or the related definitions affecting ranking of the second lien notes or
        any Guarantee in a manner which adversely affects the holders; or

    o   release any Subsidiary Guarantor from any of its obligations under its
        Guarantee, in any case otherwise than in accordance with the terms of
        the indenture.

    The provisions of the indenture concerning the 180 day standstill period
with respect to foreclosure actions and the provisions of the indenture
concerning the giving of notices of Default or an Event of Default to the First
Lien Notes Representative may not be amended without the consent of the First
Lien Notes Representative.

Governing Law

    The indenture, the second lien notes, the Guarantees and the security
documents relating to Collateral located in the U.S. are governed by, and
construed in accordance with, the laws of the State of New York, except to the
extent the laws of another jurisdiction may be mandatorily applicable to certain
matters under the security documents. The security documents relating to

Concerning The Trustee

    Firstar Bank, National Association acts as Trustee. Its address is 101 East
5th Street, St. Paul, Minnesota 55101, attn: Corporate Trust Department.

    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 incorporated by reference into

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. If the
Trustee acquires any conflicting interest as described in the TIA, it must

       (2) which becomes Indebtedness of Abraxas or a Restricted Subsidiary in
    connection with the acquisition of assets from such Person.

Acquired Indebtedness does not include Indebtedness not incurred in connection
with, or in anticipation or contemplation of, such Person becoming a Restricted
Subsidiary or such acquisition, merger or consolidation.

    "Adjusted Consolidated Net Tangible Assets" means (without duplication),  as
of the date of determination the sum of:

               development or exploitation activities, in each case calculated

    deemed to have been in effect during the Four Quarter Period;

    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 such
    agreements.

                          DESCRIPTION OF CAPITAL STOCK

Common Stock

         Abraxas is authorized to issue 50,000,000 shares of common stock, par
value $.01 per share. At January 20, 2000, there were 22,747,118 shares of
Abraxas common stock issued and outstanding. Holders of the common stock are
entitled to cast one vote for each share held of record on all matters submitted
to a vote of stockholders and are not entitled to cumulate votes for the
election of directors. Holders of common stock do not have preemptive rights to
subscribe for additional shares of common stock issued by Abraxas.

         Holders of the common stock are entitled to receive dividends as may be
declared by the Board of Directors out of funds legally available therefor.
Under the terms of the first lien notes indenture and the second lien notes
indenture, Abraxas may not pay dividends on shares of the common stock. In the
event of liquidation, holders of the common stock are entitled to share pro rata
in any distribution of Abraxas' assets remaining after payment of liabilities,
subject to the preferences and rights of the holders of any outstanding shares
of Preferred Stock. All of the outstanding shares of the common stock are fully
paid and nonassessable.

         References herein to Abraxas' common stock include the common share
purchase rights distributed by Abraxas to its stockholders on November 17, 1994
as long as they trade with the common stock. See "-- Stockholder Rights Plan".

Preferred Stock

         Abraxas' Articles of Incorporation authorize the issuance of up to
1,000,000 shares of Preferred Stock, par value $.01 per share, in one or more
series. The Board of Directors is authorized, without any further action by the
stockholders, to determine the dividend rights, dividend rate, conversion
rights, voting rights, rights and terms of redemption, liquidation preferences,
sinking fund terms and other rights, preferences, privileges and restrictions of
any series of Preferred Stock, the number of shares constituting any such
series, and the designation thereof. The rights of the holders of common stock
will be subject to, and may be adversely affected by, the rights of holders of
any Preferred Stock that may be issued in the future.

Contingent Value Rights

         General. The CVRs were issued under a CVR Agreement between Abraxas and
American Stock Transfer & Trust Company. The following description is a summary
of the material provisions of the CVRs and the CVR Agreement. It does not
restate the CVR Agreement in its entirety. We urge you to read the CVR Agreement
because it, not this description, defines your rights as a holder of CVRs. A
copy of the CVR Agreement may be obtained from Abraxas. The definitions of
certain capitalized terms used in the following summary are set forth below
under "Certain Definitions."


         Issuance of Shares at Maturity Date or Extended Maturity Date. The CVR
Agreement provides that, subject to adjustment as described under "Antidilution"
below, Abraxas will be required to issue to each holder of the CVRs on December
21, 2000, unless Abraxas will, in its sole discretion, extend the Maturity Date
to May 21, 2001, then on the Extended Maturity Date, for each CVR held by such
CVR Holder, a number of shares of Abraxas common stock, if any, equal to (a) the
Target Price minus the Current Market Value divided by (b) the Current Market
Value; provided, however, in no event shall more than 62,014,179 shares of
Abraxas common stock be issued in exchange for the CVRs, in the aggregate, at
the Maturity Date or more than 104,365,326 shares of Abraxas common stock be
issued in exchange for the CVRs, in the aggregate, at the Extended Maturity
Date, such maximum number of shares being subject to adjustment as described
under "Antidilution" below. Such determination by Abraxas absent manifest error
will be final and binding on Abraxas and the CVR Holder.


                                      116
<PAGE>
         Abraxas may at its option extend the Maturity Date to the Extended
Maturity Date. Such option will be exercised by (i) publishing notice of an
extension in the Authorized Newspaper or (ii) furnishing notice to the CVR
Holders of such extension, in each case, not less than one business day
preceding the Maturity Date; provided, however, that no defect in any such
notice will affect the validity of the extension of the Maturity Date to the
Extended Maturity Date, and that any notice when published and mailed to a CVR
Holder whether or not actually received by such CVR Holder.

         If the number of shares ultimately issuable under the CVRs is greater
than the number of authorized and unissued shares Abraxas has available at that
time, Abraxas will be required either to increase the authorized number of
shares of Abraxas common stock or to effect a reverse stock split in order to
increase the number of authorized and unissued shares of Abraxas common stock to
an amount sufficient to satisfy the number of shares issuable under the CVRs.

         Determination that No Shares are Issuable With Respect to the CVRs. If
the Current Market Value of a share of the Abraxas common stock equals or
exceeds $5.68 on the Maturity Date or $5.97 on the Extended Maturity Date, as
the case may be, no shares of Abraxas common stock will be issuable with respect
to the CVRs. In addition, the CVRs will terminate if the average of the Per
Share Market Value equals or exceeds the Target Price for any period of 30
Trading Days during any 45 consecutive Trading Days.

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


         Antidilution. In the event Abraxas in any manner subdivides (by stock
split, stock dividend or otherwise) or combines (by reverse stock split or
otherwise) the number of outstanding shares of Abraxas common stock, Abraxas
will similarly subdivide or combine the CVRs and will appropriately adjust the
Target Price and the maximum number of shares issuable on the Maturity Date and
on the Extended Maturity Date. Whenever such an adjustment is made, Abraxas
will:


         o  promptly prepare a certificate setting forth such adjustment and a
            brief statement of the facts accounting for such adjustment,

         o  promptly file with American Stock Transfer a copy of such
            certificate, and

         o  mail a brief summary thereof to each CVR Holder.


         American Stock Transfer will be fully protected in relying on any such
certificate and on any adjustment therein contained. Such adjustment absent
manifest error will be final and binding on Abraxas and the CVR Holders. Each
outstanding CVR Certificate will 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 or merge with or 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 assumes Abraxas' obligations under the
CVRs and the CVR Agreement and (ii) Abraxas delivers to American Stock Transfer
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 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 SEC.


         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 Abraxas


                                      117
<PAGE>

common stock, the holders of the CVRs would be entitled to receive securities of
the Surviving Person or such other consideration that holders of shares of
Abraxas common stock received in such a transaction based upon the price per
share received by holders of shares of Abraxas common stock or, if the Current
Market Value is higher, then based upon the Current Market Value.


         Prohibition on Short Positions in the Abraxas Common Stock. During the
Valuation Period, holders of CVRs will be prohibited under the terms of the CVR
Agreement from establishing short positions in Abraxas common stock or in
derivatives of Abraxas common stock.

         Certain Definitions.


         "Authorized Newspaper" means The Wall Street Journal, or if The Wall
Street Journal shall cease to be published, or, if the publication or general
circulation of The Wall Street Journal shall be suspended for whatever reason,
such other English language newspaper we select with general circulation in The
City of New York, New York.


         "Current Market Value" means with respect to the Maturity Date and the
Extended Maturity Date, the average of the highest closing bid prices during
normal trading hours in the over-the-counter market as reported on the OTC
Bulletin Board (or, if shares of Abraxas are traded over-the-counter as reported
on by the NASDAQ Stock Market or the NASDAQ Small Cap Market or listed on a
securities exchange, in such over-the-counter market or on such exchange) of
shares of Abraxas common stock for any 30 Trading Days during any 45 consecutive
Trading Day period that begins and ends in the Valuation Period.

         "Extended Maturity Date" means May 21, 2001.

         "Maturity Date" means December 21, 2000.

         "Person" means any individual, corporation, partnership, joint venture,
association, joint-stock company, trust, unincorporated organization or
government or any agency or political subdivision thereof.

         "Per Share Market Value" means on any particular date

         (a) the closing bid price per share of Abraxas common stock on such
date on the principal stock exchange on which Abraxas common stock has been
listed or, if there is no such price on such date, then the closing bid price on
such exchange on the date nearest preceding such date, or

         (b) if Abraxas common stock is not listed on any stock exchange, the
average of the high and low sales prices for a share of Abraxas common stock in
the over-the-counter market, as reported by the NASDAQ Stock Market or the
NASDAQ Small Cap Market for such date, or, if there is no such price on such
date, then the average of the high and low sales prices on the date nearest
preceding such date, or

         (c) if Abraxas 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 Abraxas common stock in the over-the-counter market as reported
on the OTC Bulletin Board (or any similar organization or agency succeeding to
its functions of reporting prices), or

         (d) if Abraxas common stock is no longer publicly traded, as determined
by a nationally recognized or major regional investment banking firm or firm of
independent certified public accountants of recognized standing (which may be
the firm that regularly examines the financial statements of Abraxas) selected
in good faith by the Board of Directors of Abraxas.

         "Surviving Person" means any other Person into which Abraxas shall
consolidate with or merge into or the Person which acquires by conveyance or
transfer or which leases, the properties and assets of Abraxas substantially as
an entirety.

                                      118
<PAGE>

         "Target Price" means:

Market or the NASDAQ Small Cap Market, or (c) if Abraxas common stock is not
traded on the NASDAQ Stock Market or the NASDAQ Small Cap Market, a day on which
Abraxas common stock is traded in the over-the-counter market as reported on the
OTC Bulletin Board (or any similar organization or agency succeeding to its
functions of reporting prices).

         "Valuation Period" means the period beginning on the date of the
closing of the exchange offer and ending on the Maturity Date or the Extended
Maturity Date, as the case may be.

Warrants

         Abraxas has warrants outstanding to purchase an aggregate of 13,500
shares of Abraxas common stock. Associated Energy Managers, Inc. ("AEM"), has
Warrants to purchase 13,500 shares at an exercise price of $7.00 per share. AEM
has certain registration rights with respect to shares of the Abraxas common
stock issued pursuant to the exercise of such warrants. See " -- Registration
Rights."

         All outstanding warrants contain provisions that protect AEM against
dilution by adjusting the price at which the warrants are exercisable and the
number of shares of the Abraxas 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 at less than the current
market 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.

Option Plans


         Pursuant to the Abraxas Petroleum Corporation 1984 Incentive Stock
Option Plan (the "ISO Plan"), the Abraxas Petroleum Corporation 1993 Key
Contributor Stock Option Plan (the "1993 Plan") and the Abraxas Petroleum
Corporation 1994 Long Term Incentive Plan (the "LTIP"), We grant to our
employees and officers (including our directors who are also employees)
incentive stock options and non-qualified stock options. The ISO Plan, the 1993
Plan and the LTIP are administered by the compensation committee which, based
upon the recommendation of the Chief Executive Officer, determines the number of
shares subject to each option. At February 10, 2000, there were options to
purchase 1,884,557 shares of Abraxas common stock outstanding, of which 690,883
were fully vested at an average exercise price of $2.06 per share. Abraxas
intends to adopt a new stock-based incentive plan providing for the issuance of
incentive stock options, non-qualified stock options and other stock-based
incentive compensation representing up to ten percent of the number of fully
diluted shares outstanding as of the time of adoption of the plan.

Registration Rights

         The shares of the Abraxas common stock to be received by AEM upon
exercise of warrants and any shares of the Abraxas common stock owned by
Endowment Energy Partners, L.P. and Endowment Energy Partners II, Limited
Partnership 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 Abraxas
common stock or securities convertible into Abraxas 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 Abraxas
common stock owned by EEP and EEP II other than the 211,500 shares of Abraxas
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 Abraxas 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 Abraxas
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 a Registration Rights Agreement with Halcyon/Alan B.
Slifka Management Company LLC and Franklin Resources, Inc., in the event that
Abraxas proposes to register any shares of its common stock or debt securities
under the Securities Act for its own account, except in certain circumstances,
Halcyon and Franklin are entitled to unlimited incidental registrations, subject
to the right of the underwriters of any such offering to limit the number of
shares included in such registration. Halcyon and Franklin each have the
additional right to require Abraxas to effect one demand registration of all of
the second lien notes, Abraxas common stock and contingent value rights (and any
securities issuable pursuant to the terms thereof) issued to them pursuant to
the exchange offer, subject to certain conditions and limitations including the
right of the underwriters of such an offering to limit the number of shares
included in such registration. In addition, Abraxas has agreed to pay all
expenses in connection with a demand or incidental registration except for
underwriting discounts and selling commissions which shall be borne by Halcyon
and Franklin. Abraxas has agreed to customary indemnities including an agreement
to indemnify, subject to certain limited exceptions, Halcyon and Franklin in
connection with a demand registration and an incidental 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


                                      120
<PAGE>

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 Abraxas 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 "Stockholder Rights Plan"). Under the terms of the
Stockholder Rights Plan, the Board of Directors of Abraxas declared a dividend
of one common share purchase right ("Stockholder Right") on each share of the
Abraxas common stock outstanding on November 17, 1994. Each Stockholder Right
entitles the holder thereof to buy one share of Abraxas common stock at an
exercise price of $40 per share, subject to adjustment.

         The Stockholder 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 Stockholder Rights then become exercisable (unless redeemed by the
Board of Directors) for a number of shares of Abraxas common stock having a
market value of four times the exercise price of the Stockholder Right. If the
acquiror were to conclude the acquisition of Abraxas, the Stockholder Rights
would then become exercisable for shares of the controlling/surviving
corporation having a value of four times the exercise price of the Stockholder
Rights. If the Stockholder 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 Stockholder Rights Plan provides that the Stockholder Rights may
be redeemed under prescribed circumstances by the Board of Directors.

         The Stockholder 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 Stockholder 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 General Corporation Law (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


                                      121
<PAGE>
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."

                                      122
<PAGE>

         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

                                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.

    "BOPD" means barrels of crude oil per day.

    "Charge" means an encumbrance, lien, claim or other interest in property
securing payment or performance of an obligation.

    "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.

    "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.


    "Gross" natural gas and crude oil wells or "gross" wells or acres is the
number of wells or acres in which we have an interest.


    "LOE" means lease operating expenses and production taxes.

    "MMBTU" means million British Thermal Units.

    "MMBTUpd" means million British Thermal Units per day.


    "MMcfpd" means million cubic feet per day.


    "Net" natural gas and crude oil wells or "net" acres are determined by
multiplying "gross" wells or acres by the our working interest in such wells or
acres.



                                      125
<PAGE>

    "Productive wells" mean producing wells and wells capable of production.

    "Proved reserves" or "reserves" means natural gas and crude oil, condensate
and NGLs on a net revenue interest basis, found to be commercially recoverable.

    "Proved undeveloped reserves" includes those proved reserves expected to be
recovered from new wells on undrilled acreage or from existing wells where a
relatively major expenditure is required for recompletion.

    "Service Well" is a well used for water injection in secondary recovery
projects or for the disposal of produced water.

    "Undeveloped acreage" means leased acres on which wells have not been
drilled or completed to a point that would permit the production of commercial
quantities of crude oil and natural gas, regardless whether or not such acreage
contains proved reserves.

The Board of Directors and Stockholders
Abraxas Petroleum Corporation

        We have audited the accompanying  consolidated balance sheets of Abraxas
Petroleum Corporation and Subsidiaries as of December 31, 1997 and 1998, and the
related consolidated  statements of operations,  stockholders' equity (deficit),
and cash flows for each of the three  years in the  period  ended  December  31,
1998.  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, 1997 and 1998, and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity  with generally
accepted accounting principles.

                        ABRAXAS PETROLEUM CORPORATION AND SUBSIDIARIES

                          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                              December 31, 1996, 1997, and 1998


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,  in the Permian Basin of western Texas,  and in Canada and the processing
of natural  gas  primarily  in Canada.  The  consolidated  financial  statements
include  the  accounts  of the Company  and its  subsidiaries.  All  significant
intercompany accounts and transactions have been eliminated in consolidation.

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.  Management
believes that it is reasonably  possible that  estimates of proved crude oil and
natural gas revenues could significantly change in the future.

Concentration of Credit Risk

        Financial  instruments  which  potentially  expose the Company to credit
risk consist  principally of trade receivables,  interest rate and crude oil and
natural  gas price swap  agreements.  Accounts  receivable  are  generally  from
companies  with  significant  oil  and gas  marketing  activities.  The  Company
performs ongoing credit evaluations and, generally,  requires no collateral from
its customers.

Equipment Inventory

        Equipment  inventory   principally  consists  of  casing,   tubing,  and
compression equipment 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
of properties and successful as well as unsuccessful exploration and development
activities  are  capitalized.  The Company does not capitalize  internal  costs.
Depreciation,  depletion,  and amortization  (DD&A) of capitalized crude oil and
natural  gas  properties  and  estimated  future  development  costs,  excluding
unevaluated,  unproved properties,  are based on the  unit-of-production  method
based on proved  reserves.  Net  capitalized  costs of crude oil and natural gas
properties,  less related deferred taxes, are limited,  by country, to the lower
of unamortized cost or the cost ceiling, defined as the sum of the present value
of  estimated  future net revenues  from proved  reserves  based on  unescalated
discounted at 10 percent,  plus the cost of properties not being  amortized,  if
any,  plus the lower of cost or  estimated  fair  value of  unproved  properties
included in the costs being amortized, if any, less related income taxes. Excess
costs are  charged to proved  property  impairment  expense.  No gain or loss is
recognized  upon sale or  disposition  of crude oil and natural gas  properties,
except in unusual circumstances.



                                      F-8
<PAGE>

        Unevaluated properties not currently being amortized included in oil and
gas properties  were  approximately  $11,519,000 and $10,675,000 at December 31,
1997 and 1998,  respectively.  The  properties  represented  by these costs were
undergoing exploration activities or are properties on which the Company intends
to commence  activities in the future. The Company believes that the unevaluated
properties  at  December  31,  1998 will be  substantially  evaluated  in six to
thirty-six months and it will begin to amortize these costs at such time.

Other Property and Equipment

        Other  property  and  equipment  are  recorded  on the  basis  of  cost.
Depreciation  of gas gathering and processing  facilities and other property and
equipment is provided  over the 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.

Hedging

        The  Company  periodically  enters into  contracts  to hedge the risk of
future crude oil and natural gas price  fluctuations.  Such contracts may either
fix or  support  crude oil and  natural  gas prices or limit the impact of price
fluctuations  with respect to the Company's  sales of crude oil and natural gas.
Gains and  losses  on such  hedging  activities  are  recognized  in oil and gas
production revenues when hedged production is sold.

Stock-Based Compensation

        Statement of Financial  Accounting  Standards No. 123,  "Accounting  for
Stock-Based  Compensation,"  ("Statement 123") encourages, but does not require,
companies to record  compensation  cost for  stock-based  employee  compensation
plans at fair  value.  The  Company  has  chosen  to  continue  to  account  for
stock-based   compensation  using  the  intrinsic  value  method  prescribed  in
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees,"  and related  interpretations.  Accordingly,  compensation  cost for
stock  options is measured as the excess,  if any, of the quoted market price of
the  Company's  stock at the date of the grant over the amount an employee  must
pay to acquire the stock.

Foreign Currency Translation

        The  functional  currency for the Company's  Canadian  operations is the
Canadian  dollar.  The Company  translates  the  functional  currency  into U.S.
dollars  based on the  current  exchange  rate at the end of the  period for the
balance  sheet and a weighted  average  rate for the period on the  statement of
operations.   Translation   adjustments  are  reflected  as  Accumulated   Other
Comprehensive Income (Loss) in Stockholders' Equity (Deficit).

Fair Value of Financial Instruments

        The Company includes fair value information in the notes to consolidated
financial  statements  when  the  fair  value of its  financial  instruments  is
materially  different from the book value. The Company assumes the book value of
those financial  instruments  that are classified as current  approximates  fair
value  because  of the  short  maturity  of these  instruments.  For  noncurrent
financial  instruments,  the Company uses quoted market prices or, to the extent
that there are no available  quoted  market  prices,  market  prices for similar
instruments.

Restoration, Removal and Environmental Liabilities

        The  estimated  costs of  restoration  and  removal of major  processing
facilities are accrued on a  straight-line  basis over the life of the property.
The estimated future costs for known environmental  remediation requirements are
accrued when it is probable that a liability has been incurred and the amount of


                                      F-9
<PAGE>
remediation   costs  can  be  reasonably   estimated.   These  amounts  are  the
undiscounted,  future estimated costs under existing regulatory requirements and
using existing technology.

Revenue Recognition

        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 net of royalties. Revenue from the processing of natural gas is recognized
in the period the service is performed.

Deferred Financing Fees

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

Federal Income Taxes

        The Company records income taxes 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.

Reclassifications

        Certain   balances  for  1996  and  1997  have  been   reclassified  for
comparative purposes.

2.  Liquidity

        The  Company's  operating  results have been  adversely  effected by the
 decline in prices of crude oil and natural gas during 1998.  In  addition,  the
 Company has significant  interest payments due on its Series D Notes in May and
 November  1999. As a result of these  conditions,  the Company has issued $63.5
 million of debt securities  ("Senior  Notes") in March,  1999. These securities
 are secured by  substantially  all of the  Company's  crude oil and natural gas
 properties  and natural gas  processing  facilities and the shares of Grey Wolf
 owned by the Company and bear  interest at 12.875%,  payable  semi-annually  on
 March 15 and September 15, commencing September 15, 1999. The Senior Notes will
 mature in 2003.  Proceeds  from the Senior  Notes  will be used to pay-off  the
 Company's existing Credit Facility,  pay-off  approximately $10 million of debt
 assumed in connection  with the Company's  acquisition  of New Cache in January
 1999 with the remainder being used for general corporate purposes.

        The Company has  implemented  a number of measures to conserve  its cash
resources,  including  postponement  of exploration  and  development  projects.
However, while these measures will help conserve the Company's cash resources in
the near term,  they will also limit the  Company's  ability  to  replenish  its
depleting  reserves,  which could negatively impact the Company's operating cash
flow and results of operations in the future.

3.  Acquisitions and Divestitures

Pacalta Properties Acquisition

        In October 1997,  Canadian Abraxas Petroleum Limited (Canadian Abraxas),
a wholly owned subsidiary of the Company, and Grey Wolf Exploration,  Inc. (Grey
Wolf) completed the acquisition of the Canadian assets of Pacalta Resources Ltd.
(Pacalta  Properties) for approximately  $14,000,000  (CDN$20,000,000)  and four
million Grey Wolf special warrants valued at approximately $1,375,000.  Canadian
Abraxas acquired an approximate 92% interest in the Pacalta Properties, and Grey
Wolf acquired an  approximate  8% interest.  In July 1998 Grey Wolf acquired the
remaining interest in the Pacalta Properties from Canadian Abraxas.

                                      F-10
<PAGE>
        The acquisition was accounted for as a purchase,  and the purchase price
was  allocated  to the crude oil and  natural gas  properties  based on the fair
values of the  properties  acquired.  The  transaction  was financed  through an
advance from the Company with funds which were obtained through borrowings under
the Company's Credit Facility. Results of operations from the Pacalta Properties
have been included in the consolidated financial statements since October 1997.

CGGS Acquisition

        In November  1996,  the Company,  through its wholly  owned  subsidiary,
Canadian  Abraxas  purchased  100%  of the  outstanding  capital  stock  of CGGS
Canadian Gas Gathering Systems Inc. (CGGS) for approximately $85,500,000, net of
the CGGS cash acquired and including  transaction costs. CGGS owns producing oil
and gas  properties in western  Canada and adjacent gas gathering and processing
facilities as well as undeveloped  leasehold  properties.  Immediately after the
purchase,  CGGS was merged with and into Canadian  Abraxas.  The acquisition was
accounted  for as a purchase and the purchase  price was allocated to the assets
and liabilities based on estimated fair values.  The transaction was financed by
a portion of the proceeds  from the offering of  $215,000,000  of Senior  Notes.
Results  of  operations  from  Canadian   Abraxas  have  been  included  in  the
consolidated financial statements since November 1996.

Wyoming Properties Acquisition and Divestiture

        In September 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. for
$47,500,000.  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  through
borrowings under the Company's bridge facility referred to in Note 4. Results of
operations from the Wyoming  Properties  have been included in the  consolidated
financial statements since September 1996.

        In  November  1998,  the  Company  sold  its  interest  in  the  Wyoming
Properties  to  Abraxas   Wamsutter  L.P.  a  Texas  limited   partnership  (the
"Partnership")  for approximately  $58.6 million and a minority equity ownership
in the  Partnership.  A subsidiary of the Company,  Wamsutter  Holdings,  Inc. a
Wyoming corporation,  (the "General Partner"),  will initially own a one percent
interest and act as General  Partner of the  Partnership.  After certain payback
requirements  are  satisfied,  the  Company's  interest  will  increase  to  35%
initially and could  increase to as high as 65%. The Company will also receive a
management fee and reimbursement of certain overhead costs from the Partnership.

Portilla and Happy Fields Acquisition

        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  Pension  Fund's
interest in the Portilla Field  (together,  the Portilla and Happy  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),  was 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.

        In November  1996,  the  Company  closed an  agreement  with the Limited
Partner and certain  noteholders  (Noteholders) of the Partnership,  pursuant to
which the Company obtained 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  paid to the Limited


                                      F-11
<PAGE>
Partner and the Noteholders  was $6,961,000.  The Company also paid off the Bank
Loan which had an outstanding  principal  balance of approximately  $20,051,000,
and assumed a crude oil and natural gas price swap agreement.

        As  a  result  of  obtaining  the  Limited  Partner's  interest  in  the
Partnership,  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 has included 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.  The  purchase  was  financed  by a portion of the
proceeds from the offering of the Senior Notes.  The Company  recorded its share
of the net loss of the Partnership from March 1996 to November 1996 of $513,000.
The Company also assumed and wrote off the remaining deferred financing fees and
organization costs of the Partnership. Gross revenues and expenses from both the
Company's  original  interest in the  Portilla  and Happy  Fields as well as the
interest in the Portilla  Field  previously  owned by the Pension Fund have been
included in the consolidated financial statements since November 1996.

Grey Wolf Acquisition

        In January 1996,  the Company made a $3,000,000  investment 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,
Canada corporation whose common shares are traded on The Alberta Stock Exchange.
The  acquisition  was  accounted  for as a purchase and the  purchase  price was
allocated to the assets and  liabilities  based on the fair  values.  Results of
operations  of  Cascade  have  been  included  in  the  consolidated   financial
statements since January 1996. During 1997,  Cascade acquired 100% of the common
stock of Grey Wolf in exchange for the  issuance of  additional  Cascade  common
shares to the Grey Wolf  shareholders  and the cancellation of the common shares
of Cascade held by Grey Wolf. This  transaction  resulted in the share ownership
of  Cascade  previously  held  by  Grey  Wolf  being  passed  to the  Grey  Wolf
shareholders, and Grey Wolf was merged into Cascade.

East White Point and Stedman Island Fields Acquisition

        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
$9,271,000  before  adjustment  for  accrual  of net  revenue  to  closing.  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 through proceeds of the sale
of the Senior Notes.  Results of  operatioins  from these  properties  have been
included in the  consolidated  financial  statements since November 1, 1996. The
Company recorded the net purchase price of  approximately  $9,271,000 to its oil
and gas properties.

        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  (Notes).  In January  1997,  the Notes were  exchanged for Series B Notes,
which have been  registered  under the  Securities Act of 1933 (Series B Notes).
The form and terms of the  Series B Notes  are the same as the  Notes  issued on
November 14, 1996. Interest at 11.5% is payable  semi-annually in arrears on May
1 and November 1 of each year, commencing on May 1, 1997. The Series B Notes are
general unsecured  obligations of the Company and Canadian Abraxas and rank pari
passu in right of payment to all future subordinated indebtedness of the Company
and Canadian Abraxas. The Series B Notes are, however,  effectively subordinated
in right of  payment to all  existing  and future  secured  indebtedness  to the
extent of the value of the assets  securing such  indebtedness.  The Company and
Canadian  Abraxas  are joint and  several  obligors  on the Series B Notes.  The
Series B Notes are redeemable, in whole or in part, at the option of the Company
and Canadian  Abraxas on or after November 1, 2000, at the  redemption  price of
105.75% through  October 31, 2001,  102.87% through October 31, 2002 and 100.00%
thereafter plus accrued interest. In addition,  any time on or prior to November
1, 1999, the Company and Canadian  Abraxas may redeem up to 35% of the aggregate
principal amount of the Series B Notes originally  issued with the cash proceeds
of one or more equity offerings at a redemption price of 111.5% of the aggregate
principal  amount of the Series B Notes to be redeemed  plus  accrued  interest,
provided,  however,  that  after  giving  effect  to such  redemption,  at least
$139,750,000  aggregate principal amount of Series B Notes remains  outstanding.
The Series B Notes were issued  under the terms of an Indenture  dated  November
14, 1996 that contains,  among others,  certain  covenants which generally limit
the ability of the Company to incur additional  indebtedness other than specific
indebtedness  permitted  under the  Indenture,  including  the  Credit  Facility
discussed below,  provided  however,  if no event of default is continuing,  the
Company  may  incur  indebtedness  if  after  giving  pro  forma  effect  to the
incurrence  of  such  debt  both  the  Company's  consolidated  earnings  before
interest,  taxes,  depletion and amortization  (EBITDA)  coverage ratio would be
greater than 2.25 to 1.0 if prior to November 1, 1997, and at least equal to 2.5
to 1.0 thereafter,  and the Company's adjusted consolidated net tangible assets,
as defined, are greater than 150% of the aggregate consolidated  indebtedness of
the Company or the  Company's  adjusted  consolidated  net  tangible  assets are
greater than 200% of the aggregate consolidated indebtedness of the Company. The
Indenture also contains other covenants  affecting the Company's  ability to pay
dividends on its common stock, sell assets and incur liens.

                                      F-13

        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  and  borrowed  $85,000,000
which was used to repay all amounts due under its previous credit  agreement and
to finance the purchase of the Wyoming Properties.

        On November 14, 1996, the Company repaid all amounts  outstanding  under
the bridge  facility with proceeds  from the offering of  $215,000,000  of Notes
described  above and  entered  into an amended  and  restated  credit  agreement
(Credit Facility) with the Lenders and Union Bank of California.  On October 14,
1997, the Company amended the Credit Facility to provide for a revolving line of
credit  with  an  availability  of  $40,000,000,  subject  to a  borrowing  base
condition.  At December  31, 1997 and 1998,  $31,500,000  and  $15,700,000  were
outstanding under the Credit Facility.

        Commitments available under the 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. Amounts due under
the Credit  Facility will be secured by the Company's oil and gas properties and
plants.  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 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 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
Credit  Facility is based on a facility usage grid. If the borrowings  under the
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 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 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  interest  rate at
December 31, 1998 was 6.57%.

        The 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 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
Company is obligated to pay the Lenders on a quarterly basis a commitment fee of
0.50% per annum on the average  unused  portion of the commitment in effect from
time to  time.  The  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.  As of December 31,
1998,  the Company  was not in  compliance  with the EBITDA to interest  expense
ratio requirement under the Credit Facility. This Credit Facility,  however, was
fully  redeemed with proceeds from the Company's  issuance of the Senior Secured
Notes on March 26, 1999 as discussed in Note 2. Should crude oil prices continue


                                      F-14
<PAGE>
to decline,  a further write-down of the Company's oil and gas properties may be
required (see Note 16).

        In January 1998, the Company and Canadian Abraxas  completed the sale of
$60,000,000  aggregate principal amount of 11.5% Senior Notes due 2004, Series C
(Series C Notes).  The Series C Notes are general  unsecured  obligations of the
Company and  Canadian  Abraxas and rank pari passu in right to all  existing and
future  indebtedness of the Company and Canadian  Abraxas and on parity with the
Series B Notes  and  senior  in  right of  payment  to all  future  subordinated
indebtedness  of the Company and  Canadian  Abraxas.  The Series C Senior  Notes
carry similar redemption provisions to the Series B Notes and are subject to the
terms of the Indenture dated January 27, 1998 which is substantially  similar to
the  Indenture  governing the Series B Notes.  The Company and Canadian  Abraxas
sold the Series C Notes at a premium of $4,050,000  which will be amortized over
the life of the Series C Notes  resulting  in an  effective  rate of interest of
10.5%.  The  net  proceeds,  after  deducting  estimated  offering  costs,  were
$62,750,000,  $33,400,000  of which was used to repay  outstanding  indebtedness
under the Credit Facility,  except for $100,000 which remained  outstanding with
the remainder used for general corporate purposes.

        The Company's principal source of funds to meet debt service and capital
requirements  is net  cash  flow  provided  by  operating  activities,  which is
sensitive to the prices the Company  receives for its crude oil and natural gas.
The Company  periodically enters into hedge agreements to reduce its exposure to
price risk in the spot market for natural gas. However, a substantial portion of
the Company's  production will remain subject to such price risk.  Additionally,
significant capital expenditures are required for drilling and development,  and
other equipment additions.  The Company believes that cash provided by operating
activities and other financing  sources,  including,  if necessary,  the sale of
certain assets and additional  long-term debt, will provide  adequate  liquidity
for the Company's operations, including its capital expenditure program, for the
next twelve months. No assurance,  however, can be given that the Company's cash
flow from  operating  activities  will be  sufficient  to meet  planned  capital
expenditures  and debt  service in the  future.  Should the Company be unable to
generate sufficient cash flow from operating  activities to meet its obligations
and make planned  capital  expenditures,  the Company  could be forced to reduce
such  expenditures,  sell assets or 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.

        During 1996, 1997 and 1998, the Company capitalized  $465,000,  $966,000
and $414,000 of interest expense, respectively.

        The  fair  value  of the  Notes  was  approximately  $212,350,000  as of
December 31, 1998. The fair values of the credit  facilities  approximate  their
carrying  values  as  of  December  31,  1998.  The  Company  has  approximately
$1,980,000 of standby letters of credit and a $30,000  performance  bond open at
December 31, 1998.  Approximately  $30,000 of cash is  restricted  and in escrow
related to certain of the letters of credit and bond.

6.  Stockholders' Equity

Common Stock

        In 1994, the Board of Directors adopted a Stockholders'  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


                                      F-15
<PAGE>
specified  period of time after a tender or  exchange  offer.  The  Rights  will
expire in November 2004, unless earlier exchanged or redeemed.

Treasury Stock

        In March 1996,  the Board of  Directors  authorized  the purchase in the
open market of up to 500,000 shares of the Company's  outstanding  common stock,
the aggregate  purchase  price not to exceed  $3,500,000.  During the year ended
December 31, 1998 the Company  purchased 136,255 shares of its common stock at a
cost of $980,000, which were recorded as treasury stock.

7.  Stock Option Plans and Warrants

Stock Options

        The Company grants options to its officers, directors, and key employees
under various stock option and incentive plans.

        The Company's  various stock option plans have  authorized  the grant of
options to management personnel and directors for up to approximately  1,395,000
shares of the Company's  common stock.  All options  granted have ten year terms
and vest and become fully  exercisable  over four years of continued  service at
25% on each anniversary date. At December 31, 1998 approximately 279,000 options
remain available for grant.

        Pro forma  information  regarding net income (loss) and earnings  (loss)
per share is required by Statement 123, which also requires that the information
be determined  as if the Company has  accounted  for its employee  stock options
granted  subsequent  to December  31,  1994 under the fair value  method of that
Statement.  The fair value for these  options was estimated at the date of grant
using a Black-Scholes  option pricing model with the following  weighted-average
assumptions for 1996, 1997, and 1998, respectively:  risk-free interest rates of
6.25%,  6.25% and  6.25%,  respectively;  dividend  yields  of -0-%;  volatility
factors of the expected market price of the Company's common stock of .383, .529
and .667,  respectively;  and a weighted-average  expected life of the option of
six years.

        The  Black-Scholes  option  valuation  model  was  developed  for use in
estimating the fair value of traded  options which have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because the Company's  employee stock options have  characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  in
management's  opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

        For purposes of pro forma  disclosures,  the estimated fair value of the
options is amortized to expense over the options' vesting period.  The Company's
pro forma information follows (in thousands except for earnings (loss) per share
information):

</TABLE>

        Exercise  prices for options  outstanding as of December 31, 1998 ranged
from $5.00 to $8.75 The  weighted-average  remaining  contractual  life of those
options is 8.9 years.

(1) In March 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.  In March 1998,  the Company  amended the exercise price to $7.44 per
    share on all options with an existing exercise price greater than $7.44.

Stock Awards

        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 1996, 1997, and
1998,  the Company made direct  awards of common stock of 1,000  shares,  14,748
shares and 18,263  shares,  respectively,  at  weighted  average  fair values of
$5.00, $10.75 and $5.13 per share, 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 1996, 1997, and 1998, the Company made direct awards of common stock
of 4,050  shares,  7,235  shares and 4,838  shares,  respectively,  at  weighted
average fair values of $6.25, $9.87 and $14.75 per share, respectively.

        During 1996, the Company's  stockholders  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.  During 1996, each of
the seven  eligible  directors  was granted an option to purchase  8,000  common
shares at $6.75.  These options are included in the above table. No options were
granted  during  1997,  during 1998 each of the seven  eligible  directors  were
granted an option to  purchase  2,000  common  shares at $7.44 and 3,000  common
shares at $5.56.  An  additional  option was granted to an eligible  director to
purchase 4,000 common shares at $7.44.

Stock Warrants

        In connection with an amendment to one of the Company's  previous credit
agreements,  the Company granted stock warrants to the lender  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.  During  1997,  the lender
exercised  212,000 of its  warrants  on a cashless  basis and was issued  97,810
shares of the Company's common stock.

        Additionally, warrants to purchase 13,500 shares of the Company's common
stock at $7.00 per share remain outstanding from previous grants.

        At December 31, 1998,  the Company has  approximately  5,036,000  shares
reserved for future  issuance for  conversion  of its stock  options,  warrants,
Rights, and incentive plans for the Company's directors and employees.

8.  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:

        At December  31,  1998,  the  Company  had,  subject to the  limitations
discussed below,  $46,591,000 of net operating loss  carryforwards  for U.S. tax
purposes,  of which it is  estimated  a maximum of  $43,836,000  may be utilized
before it expires.  These loss  carryforwards will expire from 2002 through 2018
if not utilized. At December 31, 1998, the Company had approximately $11,900,000
of net operating loss  carryforwards for Canadian tax purposes of which $200,000
will expire in 2002,  $4,970,000 will expire in 2003,  $3,200,000 will expire in
2004 and $3,530,000 will expire in 2005.

        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 of the Internal  Revenue  Code of 1986,  as amended  (Section  382),
occurred in December 1991. Accordingly,  it is expected that the use of the U.S.
net  operating  loss  carryforwards  generated  prior to  December  31,  1991 of
$4,909,000 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 $837,000
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 U.S. net operating  loss  carryforwards  generated  through  October 1993
(including those subject to the 1991 and 1992 ownership changes discussed above)
of $8,875,000 will be limited to approximately  $1,034,000 per year,  subject to
the lower  limitations  described  above.  Of the  $8,875,000 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  $6,120,000.  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 $5,915,000  and  $32,822,000  for deferred tax assets at
December 31, 1997 and 1998, respectively.

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

9.      Related Party Transactions

        Accounts   receivable  from  affiliates,   officers,   and  stockholders
represent amounts  receivable  relating to joint interest billings on properties
which the Company operates and advances made to officers.

        In January  1996,  Grey Wolf  purchased  newly issued  shares of Cascade
representing 66 2/3% of Cascade's capital stock. As described in Note 3, in 1997
Grey Wolf merged with Cascade and the name was changed to Grey Wolf Exploration,
Inc. ("Grey Wolf"). At December 31, 1998, the Company owns  approximately 48% of
Grey Wolf.  The Company's  President as well as certain  directors  directly own
approximately 5% of Grey Wolf. Additionally the Company's President owns options
to purchase up to 800,000 shares of Grey Wolf capital stock at an exercise price
of CDN$.20 per share,  and  certain of the  Company's  directors  own options to
purchase in the  aggregate up to 1,000,000  shares of Grey Wolf capital stock at
an exercise price of CDN$.20 per share.  Grey Wolf  currently has  approximately
127,000,000 shares of capital stock outstanding.

        Grey  Wolf  owns a 10%  interest  in the  Canadian  Abraxas  oil and gas
properties and the Canadian  Abraxas gas processing  plants acquired by Canadian
Abraxas in November 1996 from CGGS and a 100% interest in the Pacalta Properties
and  manages  the  operations  of Canadian  Abraxas,  pursuant  to a  management
agreement   between  Canadian  Abraxas  and  Grey  Wolf.  Under  the  management
agreement,  Canadian  Abraxas  reimburses  Grey  Wolf  for  reasonable  costs or
expenses attributable to Canadian Abraxas and for administrative  expenses based
upon the  percentage  that  Canadian  Abraxas'  gross revenue bears to the total
gross revenue of Canadian Abraxas and Grey Wolf.

10.  Commitments and Contingencies

Operating Leases

        During the years ended  December 31, 1996,  1997,  and 1998, the Company
incurred  rent  expense  of  approximately  $179,000,   $228,000  and  $292,000,
respectively.  Future  minimum  rental  payments  are as follows at December 31,
1998:

    1999 ................................................. $ 299,000
    2000 .................................................   313,000
    2001 .................................................   354,000
    2002 .................................................   247,000
    2003 .................................................   228,000
    Thereafter ...........................................   626,000

Contingencies

        In May 1995,  certain  plaintiffs  filed a lawsuit  against  the Company
alleging negligence and gross negligence,  tortious  interference with contract,
conversion  and waste.  In March 1998, a jury found against the Company,  on May
22,  1998  final  judgement  in the amount of  approximately  $1.3  million  was
entered.  The  Company has filed an appeal.  As of March 4, 1999,  no ruling has
been  made on the  appeal.  Management  believes,  based on the  advice of legal
counsel,  that the plaintiffs'  claims are without merit and that damages should
not be  recoverable  under this  action;  however,  the  ultimate  effect on the
Company's  financial  position and results of operations cannot be determined at
this time. The Company has not established a reserve for this matter at December
31, 1998.

        Additionally,  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,  1998,  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.

        For the year ended  December  31,  1998 none of the shares  issuable  in
connection  with stock options or warrants are included in diluted  shares.  For
the year ended December 31, 1997, none of the shares issuable in connection with
stock options,  warrants,  or the conversion of preferred  stock are included in
diluted shares.  Inclusion of these shares would be  antidilutive  due to losses
incurred in those  years.  In  addition,  for the year ended  December  31, 1996
shares  issuable in connection  with the conversion of the preferred  stock were
not included in diluted shares because the effect was antidilutive.

        Stock options and warrants to purchase  approximately  875,000 shares of
common  stock at a weighted  average per share  price of $8.36 were  outstanding
during 1996.  Since the exercise price of these warrants and options was greater
than the average  market price of the common  shares,  they were not included in
the computations of diluted earnings per share.  Inclusion of these shares would
be antidilutive.

        During the fourth quarter of 1997, the Company  recorded a write-down of
its  Canadian  proved  crude oil and natural  gas  properties  of  approximately
$4,600,000  ($3,000,000,  net of taxes).  During the fourth quarter of 1998, the
Company  recorded  a  write-down  of its  United  States  proved  crude  oil and
properties of approximately $61,224,000 under the ceiling limitation.

13.  Benefit Plans

        The  Company  has a defined  contribution  plan  (401(k))  covering  all
eligible  employees of the  Company.  During  1996,  1997,  and 1998 the Company
contributed 2,500, 7,440, and 10,329 shares,  respectively,  of its common stock
held in the  treasury  to the  Plan and  recorded  the  fair  value of  $12,500,
$41,850,  and  $76,847  respectively,  as  compensation  expense.  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 employee contribution is limited to the lesser of 20%
of the employee's annual compensation or $10,000.

15.  Business Segments

        The Company conducts its operations through two geographic segments, the
United States and Canada,  and is engaged in the  acquisition,  development  and
production  of crude oil and  natural gas and the  processing  of natural gas in
each country. The Company's significant operations are located in the Texas Gulf
Coast,  the Permian Basin of western Texas and Canada.  Identifiable  assets are
those assets used in the  operations of the segment.  Corporate  assets  consist
primarily  of deferred  financing  fees and other  property and  equipment.  The
Company's revenues are derived primarily from the sale of crude oil, condensate,
natural  gas  liquids  and  natural  gas to  marketers  and  refiners  and  from
processing fees from the custom  processing of natural gas. As a general policy,
collateral is not required for receivables; however, the credit of the Company's
customers is  regularly  assessed.  The Company is not aware of any  significant


                                      F-23
<PAGE>
credit risk relating to its customers and has not experienced significant credit
losses associated with such receivables.

        In  1998  four  customers  accounted  for  approximately  58% of oil and
natural gas production and gas processing  revenues.  Three customers  accounted
for approximately 54% of United States revenue and three customers accounted for
approximately  83% of revenue in Canada.  In 1997 three customers  accounted for
approximately 40% of oil and natural gas production  revenues and gas processing
revenues.  In 1996 four  customers  accounted for  approximately  63% of oil and
natural gas production revenues and gas processing revenues.

16.  Commodity Swap Agreements

        The Company enters into commodity swap agreements (Hedge  Agreements) to
reduce its  exposure  to price risk in the spot market for crude oil and natural
gas.  Pursuant to the Hedge  Agreements,  either the Company or the counterparty
thereto is required to make payment to the other at the end of each month.

        In November 1996, the Company assumed Hedge Agreements extending through
October 2001 with a counterparty  involving various quantities and fixed prices,
These  Hedge  Agreements  provide  for  the  Company  to  make  payments  to the
counterparty to the extent the market prices  determined  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 O) price for natural gas
exceeds the above fixed prices and for the  counterparty to make payments to the
Company to the extent the market  prices are less than the above  fixed  prices.
The Company accounts for the related gains or losses (a loss of $952,000 in 1997
and a gain of  $268,000  in 1998) in crude oil and  natural  gas  revenue in the
period of the hedged  production.  The Company terminated these hedge agreements
in January 1999 and was paid $750,000 by the counterparty for such termination

        In March  1998 the  Company  entered  into a  costless  collar for 2,000
barrels  of  crude  oil with a floor  price of  $14.00  and a  ceiling  price of
$22.30.The  agreement was effective  April 1, 1998 and extends through March 31,
1999.  Under the terms the Company will be paid when the average  crude price is
below the floor price and pay the  counterparty  when the average  price exceeds
the ceiling price.  During 1998, the Company realized a gain of $282,000 on this
agreement, which is accounted for in crude oil and natural gas revenue.

17.  Proved Property Impairment

        In 1997 and 1998 the Company  recorded a write-down  of its proved crude
oil and natural gas properties of  approximately  $4,600,000,  $3,000,000  after
taxes,  and $61,224,000  under the ceiling  limitation  prescribed for companies
following the full cost method of accounting for its oil and gas properties. The
1997  write-down was related to the Company's  Canadian oil and gas  properties,
the 1998  write-down  was  related to the  Company's  United  States oil and gas
properties.  These  write-downs  were due primarily to a decrease in spot market
prices for the Company's  crude oil and natural gas. Under full cost  accounting
rules,  the  net  capitalized  costs  of oil and gas  properties,  less  related
deferred taxes, are limited by country,  to the lower of unamortized cost or the
cost  ceiling as discussed in Note 1. The risk that the Company will be required
to  write-down  the carrying  value of its crude oil and natural gas  properties
increases  when crude oil and  natural  gas prices are  depressed  or  volatile.


                                      F-25
<PAGE>
Should prices continue to decline,  a further  write-down of the Company's crude
oil and natural gas properties may be required.  If such a write-down were large
enough,  it could  result in the  occurrence  of an event of  default  under the
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.

18.  Subsequent Event

        On January 13, 1999 the Company acquired approximately 14,026,467 common
shares and associated  rights,  representing  approximately  98.8 percent of New
Cache  Petroleums,  LTD. ("New Cache") for approximately $78 million in cash and
the  assumption of  approximately  $10 million of debt.  The Company  intends to
integrate the operations of New Cache into the existing operations of its wholly
owned subsidiary Canadian Abraxas.

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, 1996,  1997, and 1998. 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.

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,  1998,  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 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.

     In March 1999, the Company consummated the sale of $63.5 million of its
12.875% Senior Secured Notes due 2003 (the "Secured Notes"). Interest on the
Secured Notes is payable semi-annually in cash in arrears on March 15 and
September 15, commencing September 15, 1999. The Secured Notes are redeemable,
in whole or in part, at the option of Abraxas on or after March 15, 2001, at the
redemption prices set forth below, plus accrued and unpaid interest to the date
of redemption, if redeemed during the 12-month period commencing on March 15 of
the years set forth below:

                                      F-39
<PAGE>
          Year                                             Percentage
          2001............................................   103.000%
          2002 and thereafter.............................   100.000%

At any time, or from time to time, prior to March 15, 2001, Abraxas may, at its
option, use all or a portion of the net cash proceeds of one or more equity
offerings to redeem up to 35% of the aggregate original principal amount of the
Secured Notes at a redemption price equal to 112.875% of the aggregate principal
amount of the Secured Notes to be redeemed, plus accrued and unpaid interest.

     The Secured Notes are senior indebtedness of Abraxas secured by a first
lien or charge on substantially all of the crude oil and natural gas properties
of Abraxas and the shares of Grey Wolf owned by Abraxas. The Secured Notes are
unconditionally guaranteed (the "Guarantees") on a senior basis, jointly and
severally, by Canadian Abraxas, New Cache and Sandia Oil & Gas Corporation
("Sandia"), a wholly-owned subsidiary of Abraxas (collectively, the
"Guarantors"). The Guarantees are secured by substantially all of the crude oil
and natural gas properties of the Guarantors and the shares of Grey Wolf owned
by Canadian Abraxas.

Upon a Change of Control, each holder of the Secured Notes will have the right
to require Abraxas to repurchase such holder's Secured 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, Abraxas will be obligated to
offer to repurchase the Secured 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

The Indenture governing the Secured Notes (the "Secured Notes Indenture")
contains certain covenants that limit the ability of Abraxas and certain of its
subsidiaries, including the Guarantors (the "Restricted Subsidiaries"), 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, 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.

     The Secured Notes Indenture provides, among other things, that the Company
may not, and may not cause or permit the Restricted Subsidiaries, to, directly
or indirectly, create or otherwise cause to permit to exist or become effective
any encumbrance or restriction on the ability of such subsidiary to pay
dividends or make distributions on or in respect of its capital stock, make
loans or advances or pay debts owed to Abraxas or any other Restricted
Subsidiary, guarantee any indebtedness of Abraxas or any other Restricted
Subsidiary or transfer any of its assets to Abraxas or any other Restricted
Subsidiary except for such encumbrances or restrictions existing under or by
reason of: (i) applicable law; (ii) the Secured Notes Indenture or the Indenture
governing the Series D Notes; (iii) customary non-assignment provisions of any
contract or any lease governing leasehold interest of such subsidiaries; (iv)
any instrument governing indebtedness assumed by the Company in an acquisition,
which encumbrance or restriction is not applicable to such Restricted Subsidiary
or the properties or assets of such subsidiary other than the entity or the
properties or assets of the entity so acquired; (v) agreements existing on the
Issue Date (as defined in the Secured Notes Indenture) to the extent and in the
manner such agreements were in effect on the Issue Date; (vi) customary
restrictions with respect to subsidiaries 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 Secured Notes Indenture or any Security Documents (as
defined in the Secured Notes Indenture) solely in respect of the assets or
capital stock to be sold or disposed of; (vii) any instrument governing certain
liens permitted by the Secured Notes Indenture, to the extent and only to the
extent such instrument restricts the transfer or other disposition of assets
subject to such lien; or (viii) an agreement governing indebtedness incurred to
refinance the indebtedness issued, assumed or incurred pursuant to an agreement
referred to in clause (ii), (iv) or (v) 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 of the Secured
Notes in any material respect as determined by the Board of Directors of the
Company in their reasonable and good faith judgment that the provisions relating
to such encumbrance or restriction contained in the applicable agreement
referred to in such clause (ii), (iv) or (v) and do not extend to or cover any
new or additional property or assets and, with respect to newly created liens,
(A) such liens are expressly junior to the liens securing the Secured Notes, (B)
the refinancing results in an improvement on a pro forma basis in the Company's
Consolidated EBITDA Coverage Ratio (as defined in the Secured Notes Indenture)
and (C) the instruments creating such liens expressly subject the foreclosure
rights of the holders of the refinanced indebtedness to a stand-still of not
less than 179 days.

Note 6.  Contingencies

     In May 1995, certain plaintiffs filed a lawsuit against the Company
alleging negligence and gross negligence, tortuous interference with contract,
conversion and waste. In March 1998, a jury found against the Company and, on
May 22, 1998 final judgment in the amount of $1.3 million was entered. The
Company has filed an appeal. Management believes that the plaintiffs' claims are
without merit and that damages should not be recoverable under this action;
however, the ultimate effect on the Company's financial position and results of
operations cannot be determined at this time. The Company has not established a
reserve for this matter at September 30, 1999.

     Additionally, 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 September 30, 1999, 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.

Note 7. New Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities", which is
required to be adopted in years beginning after June 15, 1999. In June 1999,
SFAS No. 137 was issued, which delays the required adoption of SFAS No. 133 by
one year. The statement permits early adoption as of the beginning of any fiscal
quarter after its issuance. The Statement will require the Company to recognize
all derivatives on the balance sheet at fair value. Derivatives that are not
hedges must be adjusted to fair value through income. If the derivative is a
hedge, changes in the fair value of derivatives will either be offset against
the change in fair value of the hedged assets, liabilities, of firm commitments
through earnings or recognized in other comprehensive income until the hedge
item is recognized in earnings. The ineffective portion of a derivative's change
in fair value will be immediately recognized in earnings. The Company has not
yet determined the effect of SFAS No. 133 will be on the earnings and financial
position of the Company.

Note 8. Divestitures

     On August 11, 1999, the Company closed a transaction with a major Canadian
independent to sell non-core assets owned by Canadian Abraxas. The assets were
sold for $14.6 CDN ($9.8 million U.S.,)

Note 9. Subsequent Events

     In October 1999, the Company sold a dollar denominated production payment
for $ 4.0 million relating to existing natural gas wells in the Edwards Trend in
South Texas to a unit of Southern Energy, Inc. The Company has the ability to
sell up to $50 million to Southern for additional drilling opportunities in the
Edwards Trend.

     In November 1999 the Company announced that an oral agreement had been
reached with an informal committee of the holders of the Series D Notes,
representing a majority of the outstanding principal amount of the Series D
Notes. The Company has been exploring alternatives to increase its liquidity,
including the restructuring of the Company's indebtedness. The Company has been
involved in discussions with the members of the informal committee, and as a
result of these discussions, the Company and the informal committee have agreed
to the following restructuring proposal:

     o Noteholders will exchange the Series D Notes for new notes with a face
       amount equal to 70% of the principal amount of the existing Series D
       Notes with the same interest rate;

     o The new notes will have a second priority lien on substantially all of
       the assets of Abraxas;

     o Noteholders will receive equity equal to 72% of the equity of the
       restructured company;

     o Noteholders will receive a contingent value right that will allow them to
       receive additional equity if the price of Abraxas common stock does not
       reach certain levels over the 18 month period following the consummation
       of the restructuring; and

     o Noteholders will appoint four members of a new seven-member board of
       directors

The closing of the restructuring is subject to the satisfaction of certain
customary conditions to closing including board approval and the exchange of at
least 95% of the principal amount of the Series D Notes in exchange for new
notes with terms described above.

The Company currently expects that the proposed restructuring will be completed
on or about December 15, 1999.

Note 10.  Reclassifications

     Certain balances for 1998 have been reclassified for comparative purposes.

                          REPORT OF INDEPENDENT AUDIORS

   To the Board of Directors and Shareholders
   New Cache Petroleums Ldt.

         We have audited the balance  sheet of New Cache  Petroleums  Ltd. as of
   November 30, 1998 and the related  statements  of loss and retained  earnings
   (deficiency)  and  cash  flows  for the  year  then  ended.  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 audit.

         We conducted our audit 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 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.

         In our opinion,  these  financial  statements  present  fairly,  in all
   material  respects,  the financial position of the Company as at November 30,
   1998 and the results of its  operations  and its cash flows for the year then
   ended in accordance  with  accounting  principles  generally  accepted in the
   United States.

                          Notes to Financial Statements
                          Year Ended November 30, 1998


1. Summary of Significant accounting policies

     The financial  statements of New Cache Petroleums Ltd. (the "Company") have
been prepared in accordance with accounting principles generally accepted in the
United States. Because a precise determination of many assets and liabilities is
dependent  upon  future  events,   the   preparation  of  financial   statements
necessarily  involves the use of estimates  and  approximations  which have been
made using careful  judgment.  The financial  statements  have, in  management's
opinion,  been properly  prepared  within  reasonable  limits of materiality and
within the framework of the accounting policies summarized below.

Incorporation and description of business

     The  Company is  incorporated  under the laws of the  Province  of Alberta,
Canada and is engaged in the production,  development and exploration of oil and
natural gas solely in Canada.

Petroleum and natural gas properties

     The Company  follows the full cost method of  accounting  for petroleum and
natural gas properties. Under this method, all costs associated with acquisition
of properties and successful as well as unsuccessful exploration and development
activities  are  capitalized.  The Company does not capitalize  internal  costs.
Depreciation,  depletion,  and amortization  (DD&A) of capitalized crude oil and
natural gas properties and estimated future  development  costs are based on the
unit-of-production  method.  Net capitalized  costs of crude oil and natural gas
properties  are limited to the lower of  unamortized  cost or the cost  ceiling,
defined as the sum of the  present  value of  estimated  unescalated  future net
revenues  from  proved  reserves  discounted  at 10  percent,  plus  the cost of
properties not being amortized, if any, plus the lower of cost or estimated fair
value of unproved properties included in the costs being amortized, if any, less
related income taxes.  The provision for depletion and depreciation for the year
ended  November  30,  1998  includes an amount of  $32,615,786  as a result of a
ceiling test write down.

     No gain or loss is  recognized  upon sale or  disposition  of crude oil and
natural gas properties, except in unusual circumstances.

     Unevaluated  properties not currently being  amortized  included in oil and
gas properties were $9,545,821 at November 30, 1998. The properties  represented
by these costs were undergoing exploration activities or are properties on which
the Company intends to commence activities in the future.

     Substantially  all of the  exploration  and  production  activities  of the
Company are conducted jointly with others.  These financial  statements  reflect
only the Company's proportionate interest in such activities.

Site restoration

     The estimated cost of future site  restoration and  abandonment,  including
the removal of production facilities, net of expected salvage values is based on
current estimates,  standards and technology.  An annual provision is calculated
on a  unit-of-production  basis.  Actual  restoration and abandonment  costs are
applied against the liability as incurred.


                                      F-50

Stock Options

     The Company applies the intrinsic value method prescribed by APB Opinion 25
and  related  interpretations  in  accounting  for  share  option  transactions.
Accordingly,  no compensation  cost is recognized in the accounts as options are
granted with exercise prices greater than the prevailing market price.

Hedging activity

     The Company  enters into forward and swap contracts to manage price risk on
anticipated  future  sales.  These  contracts  are  considered  speculative  for
accounting  purposes.  The estimated amount required to settle or to be received
on  settlement  of forward  contracts  at the year end is  recorded as income or
expense.

Financial instruments

     Financial  instruments of the Company comprise cash,  accounts  receivable,
bank  production  loan,   accounts  payable  and  accrued   liabilities,   large
corporations  tax payable and the  natural  gas swap  agreement  (note 7). As at
November  30, 1998 there are no  significant  differences  between the  carrying
values of these amounts and their estimated market values.

Foreign Currency Translation

     The reporting  currency of these financial  statements is the U.S.  Dollar.
The Company's functional currency is the Canadian dollar. The Company translates
the functional  currency of its balance sheet accounts to U.S.  dollars based on
the November 30, 1998 exchange rate.  The statement of loss is translated  using
the average  exchange  rate for the year ended  November 30,  1998.  Translation
adjustments are reflected as Cumulative  translation adjustment in Shareholders'
equity.

Measurement uncertainty

     The amounts  recorded for depletion and  depreciation  of the petroleum and
natural gas properties and for site  restoration  and  abandonment  are based on
estimates of reserves and future  costs.  By their nature,  these  estimates and
those related to the future cash flows used to assess impairment, are subject to
measurement  uncertainty  and the impact on the  financial  statements of future
periods could be material.

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.

2. BANK PRODUCTION LOAN

     The Company has arranged a bank  production  loan of up to Cdn  $45,000,000
(US  $29,354,207  at November 30, 1998) that will  revolve and  fluctuate  until
April  30,  1999 at which  time the  lender  has the  option  to call the  loan.
Accordingly,  the  loan has  been  classified  as  current  in  these  financial
statements.  The loan bears  interest  at bank prime rate  (November  30, 1998 -
6.75%).  A fixed and first  floating  charge  debenture of Cdn  $50,000,000  (US
$32,615,786  at November 30, 1998) over all assets and a general  assignment  of
accounts  receivable  have been  pledged as  collateral.  At  November  30, 1998
$24,769,475 was drawn under the loan facility.

     The Company paid $1,372,159 in interest during the year.

     The exercise  prices of the  outstanding  options range from $3.15 to $9.50
per share and expiry dates are from December 14, 1998 to January 1, 2003.

     Under FAS 123 the effect on loss and loss per share of the value of options
granted  computed  using the  Black-Scholes  option  pricing  model,  applying a
risk-free  interest  rate of 6% for 1998,  assuming  five year  expected  option
lives, no dividend yields and a 37% volatility on a weighted average basis would
be an increase  of  $1,350,000  and $0.09  respectively.  These  effects are not
necessarily indicative of those to be expected in future years.

5. Income taxes

     Deferred  income  taxes  reflect the net 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:

                                                                           $

     At November  30,  1998,  the Company  had  operating  losses for income tax
purposes of approximately $2,100,000 which are available for application against
future  taxable  income  and which  expire in the years  2000  ($115,000),  2001
($240,000), 2002 ($123,000), 2003 ($162,000) and 2004 ($1,460,000).

     The provision for income taxes recorded on the financial  statements differ
from the amounts  which would be obtained by applying the  statutory  income tax
rate to loss before income taxes as follows:


Computed income taxes at the statutory rate (44.62%) ............  $(17,062,503)
Depletion and depreciation on assets that were acquired without
   full tax basis ...............................................     2,448,947

     Income taxes paid during 1998 were $256,005.

6.  Loss per share

     For purposes of computing loss per share,  the Company's  weighted  average
shares outstanding during 1998 were 14,179,890.  Any potential conversions would
be anti-dilutive.

7. FINANCIAL INSTRUMENTS

     The  Company has  entered  into a natural gas basis swap  contract to hedge
against  exposure to  variations in the  realization,  in Canadian  Dollars,  of
anticipated future natural gas sales. The basis swap outstanding at November 30,
1998 results in the Company  receiving  NYMEX minus $0.82 /MMBTU in exchange for
paying the AECO C indexed  price  (denominated  in  Canadian  Dollars)  on 2,500
MMBTU/d (approximately 2.3 mmcf/d) until October 31, 2000. The fair value of the
natural    gas   basis   swap    agreement    at    November    30,    1998   is
approximately($393,941).

8. Pending accounting standards

     In 1997  Statement of Financial  Accounting  Standards No. 130,  "Reporting
Comprehensive  Income"  ("FAS 130") was  issued.  FAS 130 will be adopted in the
first  quarter  of fiscal  1999 and the  Company  will  provide  the  additional
disclosure as required.  The sole component of comprehensive income, in addition
to that noted below,  will be the change in the cumulative  translation  account
associated with the Company's Canadian Dollar functional currency.

     In  1998,  Statement  of  Financial  Standards  No.  133,  "Accounting  for
Derivative  Instruments and Hedging  Activities" ("FAS 133") was issued. FAS 133
establishes  accounting and reporting  standards for derivative  instruments and
for hedging activities. The Company will adopt FAS 133 for its 2000 fiscal year.
Under FAS 133,  the gains and  losses  associated  with the  Company's  swap and
forward  contracts  will no longer be recorded to income as the  estimated  fair
value of such  contracts  changes.  Under FAS 133 changes in the estimated  fair
values of swap and forward contracts will be recognized in comprehensive  income
in the period of the change.  These changes will be recorded as  adjustments  to
the hedged anticipated oil and gas sales in the period the sales occur.

9. Contingency

     The  Company  has been  named as  defendant,  along  with a number of other
defendants,  in an action filed November 19, 1996. The claim pertains to certain
petroleum and natural gas properties of the Company.  It is not possible at this
time to determine the outcome of this claim.  The Company believes that there is
very  little  likelihood  that any  damages  will be incurred as a result of the
claim.

10. Subsequent Event

     On January 5, 1999,  Canadian Abraxas  Petroleum  Limited,  a subsidiary of
Abraxas  Petroleum   Corporation  acquired  all  of  the  Company's  issued  and
outstanding common shares for cash consideration of $6.50 per common share. As a
result of the acquisition, the Company's share options were cancelled.

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,  1997,  and 1998.  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.

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 November  30, 1998,  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 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 following table sets forth the expenses (other than underwriting

Item 14. 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 Alberta Business Corporation Act ("ABCA") 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 Abraxas 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.

                                      II-1
<PAGE>
         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.

Item 17. Undertakings

         A.       The undersigned registrants hereby undertake:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment 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.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.


         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


                                      II-6
<PAGE>

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.

Antonio, Texas, on February 11, 2000.

SECTION 2.        REGISTRATION UNDER THE SECURITIES ACT.

         (a) Required Registration.

              (i) Right to Require Registration. Majority Holders of Registrable
Securities shall have the one time right to request in writing (a "Request")
(which Request shall specify the Registrable Securities intended to be disposed
of by such Holders and the intended method of distribution thereof) that the
Company register the Registrable Securities held by such Holder or Holders by
filing with the SEC a Required Registration Statement. Within ten (10) business
days from the receipt of such a Request, the Company will, give written notice
of such requested registration to all Initial Holders of Registrable Securities.
No later than the [sixtieth (60th)] calendar day after the receipt of such
Request, the Company will use all reasonable efforts to cause to be filed with
the SEC a Required Registration Statement covering the Registrable Securities
which the Company has been so requested to register by Holders thereof to the
extent necessary to permit the disposition of such Registrable Securities so to
be registered in accordance with the intended methods of distribution thereof
specified in such Request, and shall use all reasonable efforts to have such
Required Registration Statement declared effective by the SEC as soon as
reasonably practicable thereafter and to keep such Required Registration
Statement continuously effective for a period of at least sixty (60) calendar
days (or, in the case of an Underwritten Offering, such period as the
Underwriters shall reasonably require) following the date on which such Required
Registration Statement is declared effective (or such shorter period which will
terminate when all of the Registrable Securities covered by such Required
Registration Statement have been sold pursuant thereto), including, if
necessary, by filing with the SEC a post-effective amendment or a supplement to
the Required Registration Statement or the related Prospectus or any document
incorporated therein by reference or by filing any other required document or
otherwise supplementing or amending the Required Registration Statement, if

                                       6
<PAGE>
required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Required Registration Statement
or by the Securities Act, the Exchange Act, any state securities or blue sky
laws, or any rules and regulations thereunder.

              A Request may be withdrawn prior to the filing of the Required
Registration Statement by the Holder(s) which made such Request (a "Withdrawn
Request"), and a Required Registration Statement may be withdrawn prior to the
effectiveness thereof by Holders of a majority of the Registrable Securities
included therein (a "Withdrawn Required Registration"), in which case such
withdrawal shall not be treated as a Required Registration.

              The Holders shall not, without the Company's consent, be entitled
to deliver a Request for a Required Registration after the completion of the
Required Registration if less than ninety (90) calendar days have elapsed since
(A) the effective date of a prior Registration Statement in which the Holders
could have sold all of the Registrable Securities sought to be registered, (B)
in the case of a Required Registration which is effected other than by means of
an Underwritten Offering, the date of sale by the Holders of their Registrable
Securities pursuant thereto or (C) the date of withdrawal of a Withdrawn
Required Registration.

              Notwithstanding the foregoing, the Company may delay the filing of
a Required Registration Statement if (i) the Board of Directors of the Company
determines that such action is in the best interests of the Company's
stockholders, (ii) the Company has been advised by legal counsel that such
filing would require disclosure of a material financing, acquisition or other
corporate transaction or (iii) the Board of Directors determines in good faith
that there is a valid business or reason for delaying the filing, and only for
an aggregate number of days not to exceed ninety (90) days in any twelve (12)
month period (a "Blackout Period").

              The registration rights granted pursuant to the provisions of this
Section 2(a)(i) shall be in addition to the registration rights granted pursuant
to the other provisions of this Section 2.

                  (ii) Priority in Required Registrations. If a Required
Registration pursuant to this Section 2(a) involves an Underwritten Offering,
and the sole Underwriter or the lead managing Underwriter, as the case may be,
of such Underwritten Offering shall advise the Company in writing (with a copy
to each Holder requesting registration) on or before the date five (5) days
prior to the date then scheduled for such offering that, in its opinion, the
amount of Registrable Securities requested to be included in such Required
Registration exceeds the amount which can be sold in such offering without
adversely affecting the distribution of the Registrable Securities being
offered, the Company will include in such Required Registration only the amount
of Registrable Securities that the Company is so advised can be sold in such
offering; provided, however, that the Company shall be required to include in
such Required Registration: (i) all Registrable Securities requested to be
included in the Required Registration by the Holders making the request and, to
the extent not all such Registrable Securities can be included in such Required
Registration, the number of Registrable Securities to be included shall be
allocated pro rata on the basis of the number of shares of Preferred Stock or
Common Stock (whichever is applicable) beneficially owned at that time by all
the Holders requesting to participate in the Required Registration or on such
other basis as shall be agreed among the Holders, by agreement of the Majority


                                       7
<PAGE>
Holders, and (ii) if all Registrable Securities requested to be included in the
Required Registration by the Holders making the request can be so included, all
other securities requested, in accordance with any registration rights which are
granted in compliance with Section 6(a), to be included in such Required
Registration which are of the same class as the Registrable Securities and, to
the extent not all such securities can be included in such Required
Registration, the number of securities to be included shall be allocated pro
rata among the holders thereof requesting inclusion in such Required
Registration on the basis of the number of securities requested to be included
by all such holders.

         (b)      Incidental Registration.

                  (i) Right to Include Registrable Securities. If at any time
the Company proposes to register any of its Common Stock or debt securities
under the Securities Act (other than (A) any registration of public sales or
distributions solely by and for the account of the Company of securities issued
(x) pursuant to any employee benefit or similar plan or any dividend
reinvestment plan or (y) in any acquisition by the Company, (B) pursuant to
Section 2(a) hereof or (C) pursuant to the Advisors' Registration Agreement),
either in connection with a primary offering for cash for the account of the
Company or a secondary offering, the Company will, each time it intends to
effect such a registration, give written notice to all Holders of Registrable
Securities at least ten (10) business days prior to the initial filing of a
Registration Statement with the SEC pertaining thereto, informing such Holders
of its intent to file such Registration Statement and of the Holders' rights to
request the registration of the Registrable Securities held by the Holders under
this Section 2(b) (the "Company Notice"). Upon the written request of any
Initial Holder made within seven (7) business days after any such Company Notice
is given (which request shall specify the Registrable Securities intended to be
disposed of by such Initial Holder and such Initial Holder's Permitted
Transferees and, unless the applicable registration is intended to effect a
primary offering of Common Stock or debt securities for cash for the account of
the Company, the intended method of distribution thereof), the Company will use
all reasonable efforts to effect the registration under the Securities Act of
all Registrable Securities which the Company has been so requested to register
by such Initial Holders to the extent required to permit the disposition (in
accordance with the intended methods of distribution thereof or, in the case of
a registration which is intended to effect a primary offering for cash for the
account of the Company, in accordance with the Company's intended method of
distribution) of the Registrable Securities so requested to be registered,
including, if necessary, by filing with the SEC a post-effective amendment or a
supplement to the Incidental Registration Statement or the related Prospectus or
any document incorporated therein by reference or by filing any other required
document or otherwise supplementing or amending the Incidental Registration
Statement, if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Incidental Registration
Statement or by the Securities Act, any state securities or blue sky laws, or
any rules and regulations thereunder; provided, however, that if, at any time
after giving written notice of its intention to register any securities and
prior to the effective date of the Incidental Registration Statement filed in
connection with such registration, the Company shall determine for any reason
not to register or to delay registration of such securities, the Company may, at
its election, give written notice of such determination to each Initial Holder
of Registrable Securities and, thereupon, (A) in the case of a determination not
to register, the Company shall be relieved of its obligation to register any
Registrable Securities in connection with such registration (but not from its
obligation to pay the Registration Expenses incurred in connection therewith),


                                       8
<PAGE>
and (B) in the case of a determination to delay such registration, the Company
shall be permitted to delay registration of any Registrable Securities requested
to be included in such Incidental Registration Statement for the same period as
the delay in registering such other securities.

                  The registration rights granted pursuant to the provisions of
this Section 2(b) shall be in addition to the registration rights granted
pursuant to the other provisions of this Section.

                  (ii) Priority in Incidental Registrations. If a registration
pursuant to this Section 2(b) involves an Underwritten Offering of the
securities so being registered, whether or not for sale for the account of the
Company, (on a firm commitment basis) by or through one or more underwriters of
recognized standing with underwriting terms appropriate for such a transaction,
and the sole Underwriter or the lead managing Underwriter, as the case may be,
of such Underwritten Offering shall advise the Company in writing (with a copy
to each Initial Holder of Registrable Securities requesting registration) on or
before the date five (5) days prior to the date then scheduled for such offering
that, in its opinion, the amount of securities (including Registrable
Securities) requested to be included in such registration exceeds the amount
which can be sold in (or during the time of) such offering without adversely
affecting the distribution of the securities being offered (such writing to
state the basis of such belief and the approximate number of Registrable
Securities which may be distributed without such effect), then the Company will
include in such registration: (i) all the securities entitled to be sold
pursuant to such Registration Statement without reference to the incidental
registration rights of any holder (including the Holders), and (ii) the amount
of other securities (including Registrable Securities) requested to be included
in such registration that the Company is so advised can be sold in (or during
the time of) such offering, allocated, if necessary, pro rata among the holders
(including the Holders) thereof requesting such registration on the basis of the
number of the securities (including Registrable Securities) beneficially owned
at the time by the holders (including the Holders) requesting inclusion of their
securities; provided, however, that in the event the Company will not, by virtue
of this paragraph, include in any such registration all of the Registrable
Securities of any Holder requested to be included in such registration, such
Holder may, upon written notice to the Company given within three (3) days of
the time such Holder first is notified of such matter, reduce the amount of
Registrable Securities it desires to have included in such registration,
whereupon only the Registrable Securities, if any, it desires to have included
will be so included and the Holders not so reducing shall be entitled to a
corresponding increase in the amount of Registrable Securities to be included in
such registration.

             (c) Expenses. The Company agrees to pay all Registration Expenses
in connection with (i) the registration requested pursuant to Section 2(a)
whether or not such registration is consummated and (ii) each registration as to
which Holders request inclusion of Registrable Securities pursuant to Section
2(b) whether or not such registration is consummated. All Selling Expenses
relating to securities registered on behalf of the Holders shall be borne by the
Holders of shares included in such registration, other selling stockholders and
the Company pro rata on the basis of the number of shares so registered.

             (d) Effective Registration Statement: Suspension. Subject to the
third paragraph of Section 2(a)(i), a Registration Statement pursuant to Section
2(a) will not be deemed to have become effective (and the related registration
will not be deemed to have been effected) unless it has been declared effective
by the SEC prior to a request by the Holders of a majority of the Registrable
Securities included in such registration that such Registration Statement be
withdrawn; provided, however, that if, after it has been declared effective, the
offering of any Registrable Securities pursuant to such Registration Statement
is interfered with by any stop order, injunction or other order or requirement
of the SEC or any other governmental agency or court that shall have been in
effect for at least thirty (30) days, such Registration Statement will be deemed
not to have become effective, and the related registration will not be deemed to
have been effected.

             (e) Selection of Underwriters. At any time or from time to time,
the Holders of a majority of the Registrable Securities covered by a Required
Registration Statement may elect to have such Registrable Securities sold in an
Underwritten Offering and may select the investment banker or investment bankers
and manager or managers that will serve as lead and co-managing Underwriters
with respect to the offering of such Registrable Securities. No Holder may
participate in any Underwritten Offering hereunder unless such Holder (a) agrees
to sell such Holder's securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, custody agreements, indemnities, underwriting agreements and other
documents required under the terms of such Underwritten Offering.

SECTION 3.        RESTRICTIONS ON PUBLIC SALE BY THE COMPANY.

         If requested by the sole Underwriter or lead managing Underwriter(s) in
such Underwritten Offering, the Company agrees not to effect any public sale or
distribution (other than public sales or distributions solely by and for the
account of the Company of securities issued pursuant to any employee benefit or
similar plan or any dividend reinvestment plan) of any securities during the
period commencing on the date the Company receives a Request from any Initial
Holder and continuing until ninety (90) days after such Registration Statement
is declared effective by the SEC (or for such shorter period as the sole or lead
managing Underwriter shall request) unless earlier terminated by the sole
Underwriter or lead managing Underwriter(s) in such Underwritten Offering.

SECTION 4.        REGISTRATION PROCEDURES.

         In connection with the obligations of the Company pursuant to Section 2
hereof, the Company shall use all reasonable efforts to effect or cause to be
effected the registration of the Registrable Securities under the Securities Act
to permit the sale of such Registrable Securities by the Holders in accordance
with their intended method or methods of distribution, and the Company shall:

         (a) (i) prepare and (within 60 days after the end of the period within
which requests for the registration may be given to the Company or in any event
as soon thereafter as possible) file with the SEC a Registration Statement which
(x) shall be on Form S-3 (or any successor to such form), if available, (y)


                                       10
<PAGE>
shall be available for the sale or exchange of the Registrable Securities in
accordance with the intended method or methods of distribution by the selling
Holders thereof and (z) shall comply as to form in all material respects with
the requirements of the applicable form and include or incorporate by reference
all financial statements required by the SEC to be filed therewith or
incorporate by reference therein and all other information reasonably requested
by the lead managing Underwriter or sole Underwriter, if applicable, to be
included therein, (ii) use all reasonable best efforts to cause such
Registration Statement to become effective and remain effective in accordance
with Section 2, (iii) use all reasonable best efforts to not take any action
that would cause a Registration Statement to contain a material misstatement or
omission or to be not effective and usable for resale of Registrable Securities
during the period that such Registration Statement is required to be effective
and usable and (iv) cause each Registration Statement and the related Prospectus
and any amendment or supplement thereto, as of the effective date of such
Registration Statement, amendment or supplement (x) to comply in all material
respects with any requirements of the Securities Act and the rules and
regulations of the SEC and (y) not to contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading;

         (b) subject to paragraph (j) of this Section 4, prepare and file with
the SEC such amendments and post-effective amendments to each Registration
Statement, as may be necessary to keep such Registration Statement effective for
the applicable period; cause the related Prospectus to be supplemented by any
Prospectus supplement required by applicable law, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated
under the Securities Act; and comply with the provisions of the Securities Act
and the Exchange Act with respect to the disposition of all securities covered
by such Registration Statement as so amended or in such Prospectus as so
supplemented during the applicable period in accordance with the intended method
or methods of distribution by the selling Holders thereof, as set forth in such
Registration Statement. The Company shall be deemed not to have used its
reasonable best efforts to keep a Registration Statement effective during the
applicable period relating thereto if the Company voluntarily takes any action
that would result in selling Holders of the Registrable Securities covered
thereby not being able to sell such Registrable Securities during that period
unless such action is required by applicable law;

         (c) furnish to each Holder of Registrable Securities and to each
Underwriter of an Underwritten Offering of Registrable Securities and its
counsel, if any, without charge, as many copies of each Prospectus, including
each preliminary Prospectus, and any amendment or supplement thereto and such
other documents as such Holder or Underwriter may reasonably request in order to
facilitate the public sale or other disposition of any Registrable Securities;
the Company hereby consents to the use of the Prospectus, including each
preliminary Prospectus, by each Holder of Registrable Securities and each
Underwriter of an Underwritten Offering of Registrable Securities, if any, in
connection with the offering and sale of the Registrable Securities covered by
the Prospectus or the preliminary Prospectus (the Holders hereby agreeing not to
make a broad public dissemination of a form of preliminary Prospectus which is
designed to be a "quiet filing" without the Company's consent, such consent to
not be withheld unreasonably);

                                       11
<PAGE>
         (d) (i) use all reasonable best efforts to register or qualify the
Registrable Securities, no later than the time the applicable Registration
Statement is declared effective by the SEC, under all applicable state
securities or "blue sky" laws of such jurisdictions as each Underwriter, if any,
or any Holder of Registrable Securities covered by a Registration Statement,
shall reasonably request; (ii) use all reasonable efforts to keep each such
registration or qualification effective during the period such Registration
Statement is required to be kept effective; and (iii) do any and all other acts
and things which may be reasonably necessary or advisable to enable each such
Underwriter, if any, and Holder to consummate the disposition in each such
jurisdiction of such Registrable Securities owned by such Holder; provided,
however, that the Company shall not be obligated to qualify as a foreign
corporation or as a dealer in securities in any jurisdiction in which it is not
so qualified or to consent to be subject to general service of process (other
than service of process in connection with such registration or qualification or
any sale of Registrable Securities in connection therewith) in any such
jurisdiction;

         (e) notify each Holder of Registrable Securities promptly, and, if
requested by such Holder, confirm such advice in writing, (i) when the
Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of the issuance by the
SEC or any state securities authority of any stop order, injunction or other
order or requirement suspending the effectiveness of a Registration Statement or
the initiation of any proceedings for that purpose, (iii) if, between the
effective date of a Registration Statement and the closing of any sale of
securities covered thereby pursuant to any agreement to which the Company is a
party, the representations and warranties of the Company contained in such
agreement cease to be true and correct in all material respects or if the
Company receives any notification with respect to the suspension of the
qualification of the Registrable Securities for sale in any jurisdiction or the
initiation of any proceeding for such purpose, and (iv) of the happening of any
event during the period a Registration Statement is effective as a result of
which such Registration Statement or the related Prospectus contains any untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading;

         (f) furnish counsel for each such Underwriter, if any, and for the
Holders of Registrable Securities copies of any comment letters received from
the SEC or any other request by the SEC or any state securities authority for
amendments or supplements to a Registration Statement and Prospectus or for
additional information;

         (g) use all reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest
possible time;

         (h) upon request, furnish to the sole Underwriter or lead managing

without charge, at least one signed copy of each Registration Statement and any
post-effective amendment thereto, including financial statements and schedules,
all documents incorporated therein by reference and all exhibits; and furnish to
each Holder of Registrable Securities, without charge, at least one conformed
copy of each Registration Statement and any post-effective amendment thereto
(without documents incorporated therein by reference or exhibits thereto, unless
requested);

                                       12
<PAGE>
         (i) cooperate with the selling Holders of Registrable Securities and
the sole Underwriter or lead managing Underwriter of an Underwritten Offering of
Registrable Securities, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends; and enable such Registrable Securities to be in
such denominations (consistent with the provisions of the governing documents
thereof) and registered in such names as the selling Holders or the sole
Underwriter or lead managing Underwriter of an Underwritten Offering of
Registrable Securities, if any, may reasonably request at least three business
days prior to the closing of any sale of Registrable Securities;

         (j) upon the occurrence of any event contemplated by paragraph (e)(iv)
of this Section, use all reasonable efforts to prepare a supplement or
post-effective amendment to a Registration Statement or the related Prospectus,
or any document incorporated therein by reference, or file any other required
document so that, as thereafter delivered to the purchasers of the Registrable
Securities, such Prospectus will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading;

         (k) enter into customary agreements (including, in the case of an
Underwritten Offering, underwriting agreements in customary form, and including
provisions with respect to indemnification and contribution in customary form
and consistent with the provisions relating to indemnification and contribution
contained herein) and take all other customary and appropriate actions in order
to expedite or facilitate the disposition of such Registrable Securities and in
connection therewith;

              (i) make such representations and warranties to the Holders of
such Registrable Securities and the Underwriters, if any, in form, substance and
scope as are customarily made by issuers to underwriters in similar underwritten
offerings;

              (ii) obtain opinions of counsel to the Company and updates thereof
(which counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to the lead managing Underwriter, if any, and the Majority Holders
of the Registrable Securities being sold) addressed to each selling Holder and
the Underwriters, if any, covering the matters customarily covered in opinions
requested in sales of securities or underwritten offerings and such other
matters as may be reasonably requested by such Holders and Underwriters;

              (iii) obtain "cold comfort" letters and updates thereof from the
Company's independent certified public accountants addressed to the selling
Holders of Registrable Securities, if permissible, and the Underwriters, if any,
which letters shall be customary in form and shall cover matters of the type
customarily covered in "cold comfort" letters to underwriters in connection with
primary underwritten offerings;

              (iv) to the extent requested and customary for the relevant
transaction, enter into a securities sales agreement with the Holders and such
representative of the selling Holders as the Majority Holders of the Registrable
Securities covered by any Registration Statement relating to the Registration


                                       13
<PAGE>
and providing for, among other things, the appointment of such representative as
agent for the selling Holders for the purpose of soliciting purchases of
Registrable Securities, which agreement shall be customary in form, substance
and scope and shall contain customary representations, warranties and covenants;
and

              (v) deliver such customary documents and certificates as may be
reasonably requested by the Majority Holders of the Registrable Securities being

              The above shall be done (i) at the effectiveness of such
Registration Statement (and each post-effective amendment thereto) in connection
with any registration, and (ii) at each closing under any underwriting or
similar agreement as and to the extent required thereunder;

         (l) make available for inspection by representatives of the Initial
Holders of the Registrable Securities and any Underwriters participating in any
disposition pursuant to a Registration Statement and any counsel or accountant

records, pertinent corporate documents and properties of the Company and cause
the respective officers, directors and employees of the Company to supply all

Statement or amendment or supplement to a Prospectus, provide copies of such
document to the Initial Holders of Registrable Securities and to counsel to such
Initial Holders and to the Underwriter or Underwriters of an Underwritten
Offering of Registrable Securities, if any; fairly consider such reasonable
changes in any such document prior to or after the filing thereof as the counsel
to the Holders or the Underwriter or the Underwriters may request and not file
any such document in a form to which the Majority Holders of Registrable
Securities being registered or any Underwriter shall reasonably object; and make
such of the representatives of the Company as shall be reasonably requested by
the Holders of Registrable Securities being registered or any Underwriter
available for discussion of such document;

                  (ii) within a reasonable time prior to the filing of any
document which is to be incorporated by reference into a Registration Statement
or a Prospectus, provide copies of such document to counsel for the Holders;
fairly consider such reasonable changes in such document prior to or after the
filing thereof as counsel for such Holders or such Underwriter shall request;
and make such of the representatives of the Company as shall be reasonably

issued by the Company is then so qualified or listed if so requested by the
Majority Holders of Registrable Securities covered by a Registration Statement,
or if so requested by the Underwriter or Underwriters of an Underwritten
Offering of Registrable Securities, if any;

                                       14
<PAGE>

         (o) otherwise use all reasonable efforts to comply with all applicable
rules and regulations of the SEC, including making available to its security
holders an earnings statement covering at least 12 months which shall satisfy
the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

         (p) cooperate and assist in any filings required to be made with the
NASD and in the performance of any due diligence investigation by any
Underwriter in an Underwritten Offering and its counsel; and

         (q) use all reasonable efforts to facilitate the distribution and sale
of any Registrable Securities to be offered pursuant to this Agreement,
including without limitation by making road show presentations, holding meetings
with potential investors and taking such other actions as shall be requested by
the Majority Holders of Registrable Securities covered by a Registration
Statement or the lead managing Underwriter of an Underwritten Offering, in each
case subject to the reasonable availability of the Company's executives given
their other duties.

         Each selling Holder of Registrable Securities as to which any
registration is being effected pursuant to this Agreement agrees, as a condition
to the registration obligations with respect to such Holder provided herein, to
furnish to the Company such information regarding such Holder required to be
included in the Registration Statement, the ownership of Registrable Securities
by such Holder and the proposed distribution by such Holder of such Registrable
Securities as the Company may from time to time reasonably request in writing.

         Each Holder agrees that, upon receipt of any notice from the Company of
the happening of any event of the kind described in paragraph (e)(iv) of this
Section, such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to the effected Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus, contemplated by
paragraph (j) of this Section, and, if so directed by the Company, such Holder
will deliver to the Company (at the expense of the Company), all copies in its
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities which was current at the
time of receipt of such notice.

SECTION 5.        INDEMNIFICATION: CONTRIBUTION.

         (a) Indemnification by the Company. The Company agrees to indemnify and
hold harmless each Person who participates as an underwriter (any such Person
being an "Underwriter"), each Holder and their respective partners, directors,
officers and employees and each Person, if any, who controls any Holder or
Underwriter within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act as follows:

                  (i) against any and all losses, liabilities, claims, damages,
judgments and expenses whatsoever, as incurred, arising out of any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement (or any amendment or supplement thereto) pursuant to
which Registrable Securities were registered under the Securities Act, including
all documents incorporated therein by reference, or the omission or alleged
omission therefrom of a material fact required to be stated therein or necessary
to make the statements therein not misleading or arising out of any untrue

                                       15
<PAGE>

statement or alleged untrue statement of a material fact contained in any
Prospectus (or any amendment or supplement thereto), including all documents
incorporated therein by reference, or the omission or alleged omission therefrom
of a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading;

                  (ii) against any and all losses, liabilities, claims, damages,
judgments and expenses whatsoever, as incurred, to the extent of the aggregate
amount paid in settlement of any litigation, investigation or proceeding by any
governmental agency or body, commenced or threatened, or of any other claim
whatsoever based upon any such untrue statement or omission, or any such alleged
untrue statement or omission, if such settlement is effected with the written
consent of the Company; and

                  (iii) against any and all expenses whatsoever, as incurred
(including reasonable fees and disbursements of counsel chosen by any
indemnified party), incurred in investigating, preparing or defending against
any litigation, investigation or proceeding by any governmental agency or body,
commenced or threatened, in each case whether or not such Person is a party, or
any claim whatsoever based upon any such untrue statement or omission, or any
such alleged untrue statement or omission, to the extent that any such expense
is not paid under subparagraph (i) or (ii) above;

                  (iv) provided however, that this indemnity agreement does not
apply to any Holder or Underwriter with respect to any loss, liability, claim,
damage, judgment or expense to the extent arising out of any untrue statement or
alleged untrue statement of a material fact contained in any Prospectus (or any
amendment or supplement thereto), or the omission or alleged omission therefrom
of a material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, in any such case made
in reliance upon and in conformity with written information furnished to the
Company by such Holder or Underwriter expressly for use in a Registration
Statement (or any amendment thereto) or any Prospectus (or any amendment or
supplement thereto) or (y) any untrue statement or alleged untrue statement or
omission or alleged omission made in any preliminary Prospectus which is
corrected in the Prospectus and a copy of the Prospectus was not sent or given
to the person asserting any such loss, liability, claim, damage, judgment or
expense who purchased Registrable Securities.

         (b) Indemnification by Holders. Each selling Holder severally, but not
jointly, agrees to indemnify and hold harmless the Company, each Underwriter and
the other selling Holders, and each of their respective partners, directors,
officers and employees, and each Person, if any, who controls the Company, any
Underwriter or any other selling Holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any and all losses,
liabilities, claims, damages, judgments and expenses described in the indemnity
contained in Section 5(a) hereof (provided that any settlement of the type
described therein is effected with the written consent of such selling Holder),
as incurred, but only with respect to untrue statements or alleged untrue
statements of a material fact contained in any Prospectus or the omissions, or
alleged omissions therefrom of a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not


                                       16
<PAGE>

misleading, in any such case made in reliance upon and in conformity with
written information furnished to the Company by such selling Holder expressly
for use in such Registration Statement (or any amendment thereto) or such
Prospectus (or any amendment or supplement thereto); provided, however, that no
such Holder shall be liable for any claims hereunder in excess of the amount of
net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Registration Statement.

         (c) Conduct of Indemnification Proceedings. Each indemnified party or
parties shall give reasonably prompt notice to each indemnifying party or
parties of any action or proceeding commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party or parties shall not relieve it or them from any liability which it or
they may have under this indemnity agreement, except to the extent that the
indemnifying party is materially prejudiced by such failure to give notice. If
the indemnifying party or parties so elects within a reasonable time after
receipt of such notice, the indemnifying party or parties may assume the defense
of such action or proceeding at such indemnifying party's or parties' expense
with counsel chosen by the indemnifying party or parties and approved by the
indemnified party defendant in such action or proceeding, which approval shall
not be unreasonably withheld; provided, however, that, if such indemnified party
or parties determine in good faith that a conflict of interest exists and that
therefore it is advisable for such indemnified party or parties to be
represented by separate counsel or that, upon advice of counsel, there may be
legal defenses available to it or them which are different from or in addition
to those available to the indemnifying party, then the indemnifying party or
parties shall not be entitled to assume such defense and the indemnified party
or parties shall be entitled to separate counsel (limited in each jurisdiction
to one counsel for all Underwriters and another counsel for all other
indemnified parties under this Agreement) at the indemnifying party's or
parties' expense. If an indemnifying party or parties is not so entitled to
assume the defense of such action or does not assume such defense, after having
received the notice referred to in the first sentence of this paragraph, the
indemnifying party or parties will pay the reasonable fees and expenses of
counsel for the indemnified party or parties (limited in each jurisdiction to
one counsel for all Underwriters and another counsel for all other indemnified
parties under this Agreement). No indemnifying party or parties will be liable
for any settlement effected without the written consent of such indemnifying
party or parties, which consent shall not be unreasonably withheld. If an
indemnifying party is entitled to assume, and assumes, the defense of such
action or proceeding in accordance with this paragraph, such indemnifying party
or parties shall not, except as otherwise provided in this Section 5(c), be
liable for any fees and expenses of counsel for the indemnified parties incurred
thereafter in connection with such action or proceeding.

         (d) Contribution.

                  (i) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Section is
for any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms in respect of any losses, liabilities,
claims, damages, judgments and expenses suffered by an indemnified party
referred to therein, each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, liabilities, claims, damages,


                                       17
<PAGE>
judgments and expenses in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and of the selling
Holders (including, in each case, that of their respective officers, directors,
employees and agents), on the other, in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages, judgments
or expenses, as well as any other relevant equitable considerations. The
relative fault of the Company, on the one hand, and of the selling Holders
(including, in each case, that of their respective officers, directors,
employees and agents), on the other, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company, on the one hand, or by or on behalf of the
selling Holders, on the other, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The amount paid or payable by a party as a result of the losses,
liabilities, claims, damages, judgments and expenses referred to above shall be
deemed to include, subject to the limitations set forth in paragraph (c) of this
Section, any legal or other fees or expenses reasonably incurred by such party
in connection with investigating or defending any action or claim.

                  (ii) The Company and each Holder of Registrable Securities
agree that it would not be just and equitable if contribution pursuant to this
Section 5(d) were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in subparagraph (i) above. Notwithstanding the provisions of this Section
5(d), in the case of distributions to the public, an indemnifying Holder shall
not be required to contribute any amount in excess of the amount by which (A)
the total price at which the Registrable Securities sold by such indemnifying
Holder and its affiliated indemnifying Holders and distributed to the public
were offered to the public exceeds (B) the amount of any damages which such
indemnifying Holder has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

                  (iii) For purposes of this Section, each Person, if any, who
controls a Holder or an Underwriter within the meaning of Section 15 of the
Securities Act (and their respective partners, directors, officers and
employees) shall have the same rights to contribution as such Holder or
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, shall have the same rights to contribution as the Company.

SECTION 6.        MISCELLANEOUS.

         (a) Inconsistent Agreements. Except as described in the Exchange Offer
and the Advisors' Registration Rights Agreement, the Company is not a party to,
and will not on or after the date of this Agreement enter into, any agreement
which conflicts with the provisions of this Agreement nor has the Company
entered into any such agreement, and the Company will not on or after the date
of this Agreement modify in any manner adverse to the Holders any such
agreement; provided, however, that nothing in this sentence shall prohibit the
Company from granting registration rights, which become exercisable from and


                                       18

after the Closing, to any Person (a "Third Party") who becomes an owner of
shares of any of the Company's capital stock after the date hereof (including
granting incidental registration rights with respect to any Registration
Statement required to be filed or maintained hereunder) if and only if (i) the
Third-Party's registration rights (including, without limitation, demand
registration rights) provide to the Holders of Registrable Securities who seek
to participate in such registration (whether or not such registration is
initiated hereunder) rights no less favorable to such Holders than those rights
provided to the Holders hereunder as if such registration were a Required
Registration (including, without limitation, the priority provisions contained
in Section 2(a)(iii)), provided, further, however, that if such registration is
not initiated by the Initial Holders such registration shall not be deemed one
of the Required Registrations for purposes of the limitations contained in the
second paragraph of Section 2(a)(i), and (ii) the Third Party is required to
enter into the agreements provided for in Section 3 hereof (as if it were the
Company) on the terms and for the period applicable to the Company (including
preventing sales pursuant to Rule 144 under the Securities Act) if requested by
the sole Underwriter or lead managing Underwriter in an Underwritten Offering
initiated by Holders of Registrable Securities pursuant to Section 2(a). The
rights granted to the Holders hereunder do not in any way conflict with and are
not inconsistent with the rights granted to the holders of the Company's other
issued and outstanding securities under any such agreements.

         (b) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company has obtained the written consent of at least a majority
of the Holders and, if any such amendment, modification, supplement, waiver or
consent would adversely affect the rights of any Holder hereunder, the written
consent of each Holder which is affected shall be obtained; provided, however,
that nothing herein shall prohibit any amendment, modification, supplement,
waiver or consent the effect of which is limited only to those Holders who have
agreed to such amendment, modification, supplement, waiver or consent.

         (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, telex,
telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder,
at the most current address given by such Holder to the Company by means of a
notice given in accordance with the provisions of this paragraph (c), which
address initially is, with respect to each Holder as of the date hereof, the
address set forth next to such Holder's name on the signature pages hereof with
a copy to _____________________, telecopier number (___)________, and with
respect to each Holder who becomes such after the date hereof, the address of
such Holder in the stock records of the Company, (ii) if to the Company, at 500
North Loop 1604, Suite 100, San Antonio, Texas 78232, telecopier number (210)
490-8816, with a copy to Cox & Smith Incorporated, 112 E. Pecan Street, Suite
1800, San Antonio, Texas 78205, telecopier number (210) 226-8395, Attention:
Steven R. Jacobs and thereafter at such other address, notice of which is given
in accordance with the provisions of this paragraph. Notwithstanding the
foregoing, the Company shall not be obligated to provide any notice to any
Holder which is not an Initial Holder except with respect to a Required or
Incidental Registration Statement which has been filed and pursuant to which
such Holder is identified as a selling stockholder.

                                       19
<PAGE>
         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; when answered
back, if telexed; when receipt is acknowledged, if telecopied; and on the next
business day if timely delivered to a courier guaranteeing overnight delivery.
Notwithstanding the foregoing, nothing in this Section 6(c) is intended to
enlarge the class of Persons which are Holders, as defined in the preamble of
this Agreement, and thus entitled to the rights granted hereunder.

         (d) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders. If any successor, assignee or transferee of any
Holder shall acquire Registrable Securities in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Registrable
Securities such Person shall be conclusively deemed to have agreed to be bound
by and to perform all of the terms and provisions of this Agreement and to
receive the benefits hereof. For purposes of this Agreement, "successor" for any
entity other than a natural person shall mean a successor to such entity as a
result of such entity's merger, consolidation, liquidation, dissolution, sale of
substantially all of its assets, or similar transaction.

         (e) Recapitalizations, Exchanges, etc. Affecting Registrable
Securities. The provisions of this Agreement shall apply, to the full extent set
forth herein with respect to the Registrable Securities, to any and all
securities or capital stock of the Company or any successor or assign of the
Company (whether by merger, consolidation, sale of assets or otherwise) which
may be issued in respect of, in exchange for, or in substitution of such
Registrable Securities, by reason of any dividend, split, issuance, reverse
split, combination, recapitalization, reclassification, merger, consolidation or
otherwise. Upon the occurrence of any of such events, Series B Preferred Stock
and Common Stock amounts hereunder shall be appropriately adjusted if necessary.

         (f) Counterparts. This Agreement may be executed in two or more
counterparts, each of which, when so executed and delivered, shall be deemed to
be an original, but all of which counterparts, taken together, shall constitute
one and the same instrument.

         (g) Descriptive Headings, etc. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning of terms contained herein. Unless the context of this Agreement
otherwise requires: (1) words of any gender shall be deemed to include each
other gender; (2) words using the singular or plural number shall also include
the plural or singular number, respectively; (3) the words "hereof", "herein"
and "hereunder" and words of similar import when used in this Agreement shall
refer to this Agreement as a whole and not to any particular provision of this
Agreement, and Article, Section, paragraph and clause references are to the
Articles, Sections, paragraphs and clauses to this Agreement unless otherwise
specified; (4) the word "including" and words of similar import when used in
this Agreement shall mean "including, without limitation," unless otherwise
specified; (5) "or" is not exclusive; and (6) provisions apply to successive
events and transactions.

         (h) Severability. In the event that any one or more of the provisions,
paragraphs, words, clauses, phrases or sentences contained herein, or the
application thereof in any circumstances, is held invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and enforce-
ability of any such provision, paragraph, word, clause, phrase or sentence in
every other respect and of the other remaining provisions, paragraphs, words,
clauses, phrases or sentences hereof shall not be in any way affected, impaired,
or invalidated and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term. Provision, covenant or restriction. It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restriction
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

         (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO
THE CONFLICTS OF LAW PRINCIPLES THEREOF).

         (j) Specific Performance. The parties hereto acknowledge that there
would be no adequate remedy at law if any party fails to perform in any material
respect any of its obligations hereunder, and accordingly agree that each party,
in addition to any other remedy to which it may be entitled at law or in equity,
shall be entitled to compel specific performance of the obligations of any other
party under this Agreement in accordance with the terms and conditions of this
Agreement in any court of the United States or any State thereof having
jurisdiction.

         (k) Entire Agreement. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. This Agreement supersedes all prior
agreements and understandings between the Company, on the one hand, and the
other parties to this Agreement, on the other, with respect to such subject
matter.
