PROSPECTUS

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

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

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

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

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

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

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

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

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

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

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

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

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

SEE "RISK FACTORS" ON P. 16 FOR A DESCRIPTION OF CERTAIN RISKS TO BE

CONSIDERED BY HOLDERS WHO TENDER THEIR SERIES A NOTES IN THE EXCHANGE OFFER.

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

THE COMPANY

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

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

The Company was founded in 1977 by Robert L.G. Watson, the Company's Chairman of the Board, President and Chief Executive Officer. Canadian Abraxas was formed by the Company in 1996 to acquire CGGS.

BUSINESS STRATEGY

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

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

7) Does not include results of operations of the Partnership (as defined herein) from March 21, 1996 to June 30, 1996 or proceeds from the Acco Sale (as defined herein).

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

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

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

                                                                           Nine Months Ended

(3) Consists of lease operating expenses, production taxes, abandoned projects, rig operating expenses and processing expenses. (4) Does not include interest income.

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

RECENT ACQUISITIONS

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

CGGS

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

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

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

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

THE WYOMING PROPERTIES

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

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

PORTILLA AND HAPPY

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

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

EAST WHITE POINT AND STEDMAN ISLAND

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

                                   the  Subsidiary  Guarantors.  The  Guarantees
                                   will be effectively  subordinated in right of
                                   payment  to  secured   indebtedness   of  the
                                   Subsidiary Guarantors.

                                   "Indenture")  will contain certain  covenants
                                   that  limit the  ability of the  Issuers  and
                                   their  Restricted  Subsidiaries  (as  defined
                                   herein)  to,   among  other   things,   incur
                                   additional  indebtedness,  pay  dividends  or

                                   their  Restricted   Subsidiaries,   merge  or
                                   consolidate  with any  other  person or sell,
                                   assign, transfer,  lease, convey or otherwise
                                   dispose  of all or  substantially  all of the
                                   assets of either of the Issuers.

EXCHANGE OFFER; REGISTRATION RIGHTS; ADDITIONAL INTEREST

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


SUMMARY HISTORICAL AND PRO FORMA FINANCIAL INFORMATION

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

RISK FACTORS

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

HIGH DEGREE OF LEVERAGE

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

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

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


RANKING OF INDEBTEDNESS

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

REPURCHASE OF NOTES UPON A CHANGE OF CONTROL

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

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

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

NET LOSSES

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

INDUSTRY CONDITIONS; IMPACT ON COMPANY'S PROFITABILITY

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

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

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

RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS

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

SUBSTANTIAL CAPITAL REQUIREMENTS

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

INTEGRATION OF OPERATIONS; FOREIGN OPERATIONS

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

FUTURE AVAILABILITY OF NATURAL GAS SUPPLY

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

OPERATING HAZARDS; UNINSURED RISKS

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


COMPETITION

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

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

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

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

RELIANCE ON ESTIMATES OF PROVED RESERVES AND FUTURE NET REVENUE

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

CERTAIN BUSINESS RISKS

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

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

DEPLETION OF RESERVES

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

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

GOVERNMENT REGULATION

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

FRAUDULENT CONVEYANCE

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

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

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

DEPENDENCE ON KEY PERSONNEl

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

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

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

LACK OF PUBLIC MARKET

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

PURPOSE OF THE EXCHANGE OFFER

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

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


RESALE OF THE EXCHANGE NOTES

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

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

PLAN OF DISTRIBUTION

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

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

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

THE EXCHANGE OFFER

TERMS OF THE OFFER

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

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

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

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


CERTAIN EFFECTS OF THE EXCHANGE OFFER

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

EXPIRATION AND EXTENSION

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

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

CONDITIONS

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

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

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

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

HOW TO TENDER

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

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

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

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

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

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

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

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

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

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

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

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

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

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

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

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

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

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

WITHDRAWAL RIGHTS

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

ACCEPTANCE OF TENDERS

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

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

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


EXCHANGE AGENT

IBJ Schroder Bank & Trust Company has been appointed as Exchange Agent for the Exchange Offer. Letters of Transmittal must be addressed to the Exchange Agent as follows:

IBJ Schroder Bank & Trust Company One State Street
Eleventh Floor
New York, New York 10004 Attention: Corporate Trust Trustee Administration

Delivery to other than the above address will not constitute valid delivery.

SOLICITATION OF TENDERS; EXPENSES

Except as described above under "Exchange Agent," the Issuers have not retained any agent in connection with the Exchange Offer and will not make any payments to brokers, dealers or other persons for soliciting or recommending acceptances of the Exchange Offer. The Issuers will, however, reimburse the Exchange Agent for its reasonable out-of-pocket expenses in connection therewith. The Issuers will also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this Prospectus and related documents to the beneficial owners of the Series A Notes and in handling or forwarding tenders for their customers.


USE OF PROCEEDS

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

The net proceeds to the Issuers from the Offering were approximately $206.8 million after deducting discounts and estimated offering expenses payable by the Issuers. The Issuers utilized the net proceeds, primarily to (i) consummate the Recent Acquisitions, (ii) repay all indebtedness outstanding under the Company's credit facility with BTCo and ING Capital and (iii) pay certain expenses incurred in connection with the Transactions. The following table illustrates the sources and uses of proceeds:

PRO FORMA FINANCIAL INFORMATION

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

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

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

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

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

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

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

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

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

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

(dollars in thousands) The total purchase price has been allocated as follows:

       Purchase price for the outstanding

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

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

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

RESULTS OF OPERATIONS

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

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

                                                                             Nine Months Ended

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


LIQUIDITY AND CAPITAL RESOURCES

Capital expenditures for the years ended December 31, 1993, 1994 and 1995 were $26.2 million, $40.9 million and $12.3 million, respectively. For the nine months ended September 30, 1995, capital expenditures were $9.2 million compared to $58.0 million during the same period in 1996. The table below sets forth the components of these capital expenditures on a historical basis for the three years ended December 31, 1993, 1994 and 1995 and the nine months ended September 30, 1995 and 1996.

- ------------
(1) Acquisition costs include approximately 78,000 shares of Common Stock valued
at $533,000 for the year ended December 31, 1993, and 45,741 shares of Preferred
Stock valued at $4.6 million in 1994 and $1.1 million of oil and gas  properties
acquired from Cascade in the nine months ended September 30, 1996.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


NEW ACCOUNTING STANDARDS

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


BUSINESS

GENERAL

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

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

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


BUSINESS STRATEGY

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

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

                                                                        June 30,

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

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

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

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

RECENT ACQUISITIONS

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

CGGS

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

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

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

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

THE WYOMING PROPERTIES

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

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

PORTILLA AND HAPPY

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

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

EAST WHITE POINT AND STEDMAN ISLAND

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

The Company owns a 100% interest in the Portilla Plant which had aggregate capacity of approximately 20.0 MMcf of natural gas per day at September 30, 1996. During the nine months ended September 30, 1996, the Portilla Plant processed an average of approximately 17.2 MMcf of natural gas per day and extracted an average of approximately 271 Bbls of NGLs per day. The Company is currently the operator of the Portilla Plant and all of the wells in the Portilla Field.

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

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

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

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

SOUTHWESTERN WYOMING

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

WESTERN CANADA

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

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

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

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

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

EXPLORATION OPPORTUNITIES

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

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

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

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

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

RESERVES INFORMATION

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

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

(1) Does not include reserves of Cascade and Grey Wolf.
(2) Includes reserves of CGGS at September 1, 1996.

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

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

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

MARKETS AND CUSTOMERS

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

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

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

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

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

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

COMPETITION

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

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

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


REGULATORY MATTERS

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

PRICE REGULATIONS

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

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

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

THE NORTH AMERICAN FREE TRADE AGREEMENT

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

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

NATURAL GAS REGULATION

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

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

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

STATE AND OTHER REGULATION

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

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

ROYALTY MATTERS

UNITED STATES

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

CANADA

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

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

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

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

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

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

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

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

ENVIRONMENTAL MATTERS

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

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

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


TITLE TO PROPERTIES

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

EMPLOYEES

As of December 20, 1996, Abraxas had 43 full-time employees, including two executive officers, two non-executive officers, five petroleum engineers, one landman, one geologist, eleven secretarial and clerical personnel and 21 field personnel. Additionally, Abraxas retains contract pumpers on a month-to-month basis. The Company retains independent geologic and engineering consultants from time to time on a limited basis and expects to continue to do so in the future.

OFFICE FACILITIES

The Company's executive and administrative offices are located at 500 North Loop 1604 East, Suite 100, San Antonio, Texas 78232. The Company owns a 16% limited partnership interest in the partnership which owns this office building. The Company also has 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 $14,194 per month.

OTHER PROPERTIES

The Company owns 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 2.0 acres of land in Bexar County, Texas. All three properties are used for the storage of tubulars and production equipment. The Company also owns 19 vehicles which are used in the field by employees.

LITIGATION

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

STOCK 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"), the Company grants to employees and officers of the Company (including directors of the Company 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 of the Board of Directors which, based upon the recommendation of the Chief Executive Officer, determines the number of shares subject to each option. In addition to the ability to grant either incentive stock options and non-qualified stock options under the LTIP, the Compensation Committee may grant or award (a) stock appreciation rights in conjunction with stock options or independently, (b) restricted stock or (c) other stock-based awards to executive and other key employees of the Company.


EMPLOYMENT AGREEMENTS

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

COMPENSATION OF DIRECTORS

DESCRIPTION OF THE NOTES

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

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

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

PRINCIPAL, MATURITY AND INTEREST

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

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

REDEMPTION

OPTIONAL REDEMPTION.

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

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

OPTIONAL REDEMPTION UPON EQUITY OFFERINGS.

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

SELECTION AND NOTICE OF REDEMPTION

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

GUARANTEES

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

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

CHANGE OF CONTROL

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

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

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

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

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

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


CERTAIN COVENANTS

The Indenture contains, among others, the following covenants:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


EVENTS OF DEFAULT

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

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

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

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

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

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

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

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

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

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

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

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

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

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

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

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

SATISFACTION AND DISCHARGE

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

MODIFICATION OF THE INDENTURE

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

GOVERNING LAW

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

THE TRUSTEE

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

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

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, subject to the rights of the holders of the class or series of Canadian Abraxas' preferred stock. Under the terms of the New Credit Facility , Canadian 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 Canadian Abraxas' assets remaining after payment of liabilities, subject to the preferences and rights of the holders of any shares of preferred stock. All of the outstanding shares of the Common Stock are fully paid and nonassessable.

PREFERRED STOCK

ABRAXAS

General. 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.

Description of Series 1995-B Preferred Stock. Abraxas is authorized to issue 1,000,000 shares of Preferred Stock, of which 45,741 shares have been designated as the Series 1995-B Preferred Stock. The holders of the Series 1995-B Preferred Stock have the full right and power to vote with the holders of the Common Stock on all matters on which the stockholders of the Common Stock are entitled to vote. Holders of the Series 1995-B Preferred Stock are entitled to 11.11 votes for each share of the Series 1995-B Preferred Stock and are not entitled to cumulate votes in the election of directors. Holders of the Series 1995-B Preferred Stock do not have preemptive rights to subscribe for or to purchase any additional shares of the Series 1995-B Preferred Stock. All or any shares of the Series 1995-B Preferred Stock may be redeemed at the option of Abraxas at any time after January 1, 1997 at $100 per share plus the amount of accrued and unpaid dividends. If Abraxas redeems, repurchases, exchanges any security or property for, or otherwise acquires for consideration any shares of Common Stock (other than an acquisition pursuant to Rule 13e-4(h)(5) promulgated under the Exchange Act) at a price equal to or greater than $100 divided by the number of shares of Common Stock into which one share of the Series 1995-B Preferred Stock is then convertible, any holder of shares of Series 1995-B Preferred Stock may require Abraxas to redeem a number of shares of such holder's Series 1995-B Preferred Stock equal to the product of (i) the percentage of the shares of the Common Stock so redeemed or otherwise acquired times (ii) the total number of shares of the Series 1995-B Preferred Stock held by such holder at a price per share equal to the product of (x) the number of shares of Common Stock that such holder's shares of Series 1995-B Preferred Stock is then convertible times (y) the per share price paid for a share of Common Stock by Abraxas plus all accrued and unpaid dividends. Each share of Series 1995-B Preferred Stock may be converted, subject to adjustment, into 11.11 shares of the Common Stock.

Shares of the Series 1995-B Preferred Stock are entitled to a cumulative dividend of $8.00 per share per annum payable on a quarterly basis, when and if declared by the Board of Directors. In the event of the dissolution, liquidation or winding up of Abraxas, the holders of the Series 1995-B Preferred Stock shall be entitled to receive an amount of money equal to the redemption price per share plus all accrued and unpaid dividends thereon in cash or in any assets of Abraxas remaining after the debts of Abraxas have been paid in full and before any payment is made or assets set aside for payment to the holders of the Common Stock. All outstanding shares of the Series 1995-B Preferred Stock are fully paid and nonassessable.

CANADIAN ABRAXAS

Canadian Abraxas' Articles of Incorporation authorize the issuance of an unlimited number of First Preferred Shares, without par value. 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 the First Preferred Shares. The rights of the holders of Canadian Abraxas' Common Stock will be subject to, and may be adversely affected by, the rights of holders of the First Preferred Shares that may be issued in the future.

CONTINGENT VALUE RIGHTS

GENERAL. The CVRs were issued under the CVR Agreement (the "CVR Agreement") between Abraxas and First Union. 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 shall issue to each holder of the CVRs (each such person, a "CVR Holder") on the Extended Maturity Date (as defined below), for each CVR held by such CVR Holder, Abraxas shall issue a number of shares of Common Stock, if any, equal to (a) the Target Price (as defined below) minus the Current Market Value divided by (b) the Current Market Value; provided, however, in no event shall more than 1.5 shares of Common Stock be issued in exchange for each CVR at the Extended Maturity Date. Such determination by Abraxas absent manifest error shall be final and binding on Abraxas and the CVR Holder.

Determination that No Shares are Issuable With Respect to the CVRs. If the Current Market Value of a share of the Common Stock equals or exceeds $12.50 on the Extended Maturity Date, no shares of the Common Stock will be issuable with respect to the CVRs. In addition, the CVRs will terminate if the Per Share Market Value (as defined below) equals or exceeds the Target Price for any period of 30 consecutive Trading Days during the period from and after November 17, 1996 to and including November 17, 1997.

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

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

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

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

CERTAIN DEFINITIONS.

"ADJUSTED CURRENT MARKET VALUE" per share means, with respect to the Extended Maturity Date, the median of the averages of the closing bid prices of the shares of capital stock or other securities of the Surviving Person received by the holders of Common Stock in a Transaction on the principal stock exchange on which such shares of capital stock or other securities are traded during each 20 consecutive Trading Day period that both begins and ends in the Valuation Period.

"ADJUSTED TARGET PRICE" means the Target Price divided by the Conversion Ratio.

"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 as is selected by Abraxas with general circulation in The City of New York, New York.

"CONVERSION RATIO" means the number of shares of capital stock or other securities of the Surviving Person received by the holder of one (1) share of the Common Stock.

"CURRENT MARKET VALUE" means with respect to the Extended Maturity Date, the median of the averages of the closing bid prices on the NASDAQ Stock Market
(or, if the Common Stock is listed on a securities exchange, on such exchange)
of shares of the Common Stock during each 20 consecutive trading day period that both begins and ends in the Valuation Period.

"EXTENDED MATURITY DATE" means November 17, 1997.

"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 the Common Stock on such date on the principal stock exchange on which the Common Stock has been listed or, if there is no such price on such date, then the average of such prices on such exchange on the date nearest preceding such date, or (b) if the Common Stock is not listed on any stock exchange, the average of the high and low sales prices for a share of Common Stock in the over-the-counter market, as reported by the NASDAQ Stock Market for such date, or, if there are no such prices on such date, then the average of such prices on the date nearest preceding such date, or (c) if the Common Stock is not quoted on the NASDAQ Stock Market, the average of the final bid and final asked prices for a share of Common Stock in the over-the-counter market as reported by the National Quotation Bureau Incorporated (or any similar organization or agency succeeding to its functions of reporting prices), or (d) if the 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.

"TARGET PRICE" means $12.50. Upon each occurrence of an event specified under "Antidilution" above, such amount, as it may have been previously adjusted, shall be adjusted as described under "Antidilution" above.

"TRADING DAY" means (a) a day on which the Common Stock is traded on the principal stock exchange on which the Common Stock has been listed, or (b) if the Common Stock is not listed on any stock exchange, a day on which the Common Stock is traded in the over-the-counter market, as reported by the NASDAQ Stock Market, or (c) if the Common Stock is not traded on the NASDAQ Stock Market, a day on which the Common Stock is traded in the over-the-counter market as reported by the National Quotation Bureau Incorporated (or any similar organization or agency succeeding to its functions of reporting prices).

"VALUATION PERIOD" means the 60 Trading Day period immediately preceding (and including) the Maturity Date or the Extended Maturity Date.

WARRANTS

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

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

REGISTRATION RIGHTS

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

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

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

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

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

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

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

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

STOCKHOLDER RIGHTS PLAN

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

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

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

ANTI-TAKEOVER STATUTES

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

RESTRICTIONS ON CERTAIN COMBINATIONS BETWEEN NEVADA RESIDENT CORPORATIONS AND INTERESTED STOCKHOLDERS

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

NEVADA CONTROL SHARE ACT

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

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

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

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

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

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

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

CERTAIN UNITED STATES AND CANADIAN INCOME TAX CONSIDERATIONS

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

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

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

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

TAX CONSEQUENCES OF THE EXCHANGE OFFER

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

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

TAXATION OF ACCRUED STATED INTEREST ON NOTES

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

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

MARKET DISCOUNT

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

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

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

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

ACQUISITION PREMIUM

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

SALE, EXCHANGE OR OTHER TAXABLE DISPOSITION OF THE NOTES

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

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

PURCHASE OR REDEMPTION OF NOTES

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

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

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

BACKUP WITHHOLDING

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

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

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

RECEIPT OR DEEMED RECEIPT OF INTEREST

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

DISPOSITIONS OF THE NOTES AND TAX CONSEQUENCES OF THE EXCHANGE OFFER

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


TRANSACTIONS WITH RELATED PARTIES

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

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

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

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

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

BOOK-ENTRY; DELIVERY AND FORM

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

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

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

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

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

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

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

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

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

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

In the event that the Company ceases to be subject to the informational reporting requirements of the Exchange Act, the Issuers have agreed that, so long as the Series A Notes or the Exchange Notes remain outstanding, they will file with the Commission and distribute to holders of the Series A Notes or the Exchange Notes, as applicable, copies of the financial information that would have been contained in annual reports and quarterly reports, including management's discussion and analysis of financial condition and results of operations, that the Company would have been required to file with the Commission pursuant to the Exchange Act.

ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

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

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.

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

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

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

"Finding cost", expressed in dollars per BOE, is calculated by dividing the amount of total exploration and development capital expenditures (excluding any amortization with respect to deferred financing fees) by the amount of proved reserves added during the same period (including the effect on proved reserves of reserve revisions).

"G&A" means general and administrative.

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

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

"Proved developed reserves" includes only those proved reserves expected to be recovered from existing completion intervals in existing wells and those reserves that exist behind the casing of existing wells when the cost of making such reserves available for production is relatively small compared to the cost of a new well.

"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

Report of Independent Auditors

The Board of Directors and Shareholders
Abraxas Petroleum Corporation

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

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

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

ABRAXAS PETROLEUM CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 1993, 1994, and 1995

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

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

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

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

USE OF ESTIMATES

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

MARKETABLE SECURITIES

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

ACCOUNTS RECEIVABLE

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


EQUIPMENT INVENTORY

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

OIL AND GAS PROPERTIES

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

OTHER PROPERTY AND EQUIPMENT

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

STOCK-BASED COMPENSATION

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

REVENUE RECOGNITION AND MAJOR CUSTOMERS

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

DEFERRED FINANCING FEES

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


FEDERAL INCOME TAXES

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

NET INCOME (LOSS) PER COMMON SHARE

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

RECLASSIFICATIONS

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

2. ACQUISITIONS AND DIVESTITURES

TEXAS GULF COAST PROPERTIES ACQUISITION

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

WEST TEXAS PROPERTIES ACQUISITION

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


OVERRIDING ROYALTY INTEREST ACQUISITION

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

MOBIL ACQUISITION

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

GAELIC PROPERTIES

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


The condensed unaudited combined pro forma financial information for the periods presented assumes the purchases of the West Texas Properties, the Overriding Royalty Interest, the Sinton Properties, and the Gaelic Properties were effective as of January 1, 1993. The pro forma information does not necessarily represent what the actual consolidated results would have been for these periods and is not intended to be indicative of future results.

DIVESTITURE

In July 1995, the Company sold its C.S. Dean Unit for approximately $2,550,000.

3. DISCONTINUED OPERATIONS

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


4. MARKETABLE SECURITIES

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

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

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

5. RELATED PARTY TRANSACTIONS

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

In June 1994, the Company entered into a credit agreement with First Union which was subsequently amended during the year. The Company borrowed $40,906,652 during 1994 under the agreement. The borrowings were composed of advances of $32,906,652 under a revolving line of credit which was due June 1997, and $8,000,000 under a term note which was due June 15, 1995. In August 1995, the Company amended the credit agreement with First Union.

At December 31, 1995, the Company's borrowings under the credit agreement were $41,556,651. The borrowings were composed of advances of $12,656,651 and $22,900,000 under the revolving lines of credit which are due June 30, 1997, and $6,000,000 under the term notes which are also due June 30, 1997. The interest rate for the revolving credit lines is, at the option of the Company, either (a) the higher of First Union prime plus 1/4% or the federal funds rate plus 3/4%, floating, payable monthly, or (b) LIBOR plus 2 1/4% (30-, 60-, 90-, and 180-day options), with interest payable the earlier of maturity of each LIBOR tranche or quarterly. The interest rate for the term notes is, at the option of the Company, either (a) the higher of First Union prime plus 3/4% or the federal funds rate plus 1 1/4%, floating, payable monthly, or (b) LIBOR plus 3 1/4% (30-, 60-, 90-, and 180-day options), with interest payable the earlier of maturity of each LIBOR tranche or quarterly. At December 31, 1995, the $12,656,651 revolver carried interest at 8.19%, the $22,900,000 revolver carried interest at 8.06%, and the term notes at 8.16%. The revolvers provide for borrowing based principally on the Company's crude oil and natural gas reserve base, which was $44,000,000 at December 31, 1995.

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

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


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

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

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

7. SHAREHOLDERS' Equity

COMMON STOCK

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

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


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

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

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

PREFERRED STOCK

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

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


CONTINGENT VALUE RIGHTS (CVR)

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

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

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

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

TREASURY STOCK

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


8. STOCK OPTION PLANS AND WARRANTS

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

The following is a summary of activity in the stock option plans for the years ended December 31, 1994 and 1995, and the nine-month period ended September 30, 1996:

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

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


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

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

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

STOCK WARRANTS

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

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

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


9. INCOME TAXES

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

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

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

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

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

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


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

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

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

10. LEASES

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

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

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

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


11. INVESTMENT IN COAL PROPERTIES

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

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

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

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

12. BENEFIT PLANS

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


13. INCENTIVE BONUS PLAN

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

14. CONTINGENCIES

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

15. COMMODITY SWAP AGREEMENT

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

16. SUBSEQUENT EVENTS

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

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


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

17. ACQUISITIONS AND RELATED FINANCING (UNAUDITED)

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

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

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


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

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

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

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

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


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

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

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

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


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

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

Estimated Quantities of Proved Oil and Gas Reserves

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

(1) Includes 127,700 barrels of crude oil from the Company's Canadian subsidiary, Cascade, which are not included in the Company's June 30, 1996 reserve report.

All proved reserves are located within the continental United States.

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

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

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

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

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

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

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

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

CGGS CANADIAN GAS GATHERING SYSTEMS INC.

NOTES TO FINANCIAL STATEMENTS

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

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

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

FOREIGN CURRENCY TRANSLATION

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

JOINT VENTURES

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

CAPITAL ASSETS

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

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

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

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


CGGS CANADIAN GAS GATHERING SYSTEMS INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

PROVISION FOR FUTURE SITE RESTORATION

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

ROYALTIES

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

DEFERRED FINANCING COSTS

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

2. FORMATION AND UNIT SUBSCRIPTIONS

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

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

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

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

Independent Auditors' Report

To the Board of Directors of
Enserch Exploration, Inc.

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

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

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

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

ENSERCH EXPLORATION, INC.'S WAMSUTTER AREA PACKAGE

NOTES TO STATEMENTS OF REVENUES AND
DIRECT OPERATING EXPENSES

1. THE PROPERTIES

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

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

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

2. CONTINGENT LIABILITIES

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

3. OIL AND GAS RESERVES (UNAUDITED)

The following table of estimated proved and proved developed reserves of oil and gas related to the Wamsutter Area Package properties has been prepared utilizing estimates of period-end reserve quantities provided by independent petroleum consultants.

4. STANDARDIZED MEASURE (UNAUDITED)

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

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

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

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

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

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

Years Ended December 31, 1994 and 1995

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

1. BASIS OF PRESENTATION

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

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

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

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

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

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

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

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

CANADIAN ABRAXAS PETROLEUM LIMITED

NOTE TO BALANCE SHEET

September 30, 1996

1. ORGANIZATION

ORGANIZATION AND OPERATIONS

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

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

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

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

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

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

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

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

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

ITEM 22. UNDERTAKINGS

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

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

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

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

2. Dividend

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

3. Liquidations

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

FIRST PREFERRED SHARES

1. Voting Rights

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

2. Dividends

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

3. Redemption

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

5. Purchase for Cancellation

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

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

6. Liquidation

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

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

7. Amendments

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

8. Creation of Additional Shares

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

9. Approval by Holders of First Preferred Shares

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

10. Adjustment

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

a. a tribunal or court of competent jurisdiction;

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

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

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

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

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

11. Restriction on Distributions

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

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

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

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

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

In addition, the board may from time to time direct the manner in which the person or persons by whom any particular instrument or class of instruments may or shall be signed. Any signing officer may affix the corporate seal to any instrument requiring the same, but no instrument is invalid merely because the corporate seal is not affixed thereto.

3.02 Cheques, Drafts and Notes

All cheques, drafts or orders for the payment of money and all notes and acceptances and bills of exchange shall be signed by such officer or officers or person or persons, whether or not officers of the Corporation, and in such manner as the board may from time to time designate by resolution.

DIVISION FOUR
DIRECTORS

4.01 Number

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

4.02 Election and Term

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

4.03 Removal of Directors

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

             4.04        Consent

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

                         A. he was present at the meeting when he was elected or

appointed and did not refuse to act as a director, or

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

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

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

             4.05        Vacation of Office

                         A director  of the  Corporation  ceases to hold  office
when:

                         A.          he dies or resigns;

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

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

             4.06        Committee of Directors

                         The  directors  may appoint  from among their  number a

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

4.07 Transaction of Business of Committee

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

4.08 Procedure

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

4.09 Remuneration and Expenses

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

4.10 Vacancies

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

4.11 Action by the Board

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

A copy of every such resolution shall be kept with the minutes of the proceedings of the directors or committee of directors. Any such resolution in writing is effective for all purposes at such time as the resolution states regardless of when the resolution is signed.

5.12 Amendments to the Act

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

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

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

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

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

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

The board may specify in a notice calling a meeting of shareholders a time, preceding the time of such meeting by not more than forty-eight (48) hours exclusive of Saturdays and holidays, before which time proxies to be used at such meeting must be deposited.

8.16 Joint Shareholders

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

8.17 Votes to Govern

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

8.18 Show of Hands

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

8.19 Ballots

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

8.20 Adjournment

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

8.21 Resolution in Lieu of a Meeting

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

8.22 Only One Shareholder

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

DIVISION NINE
SHARES

9.01 Non-Recognition of Trusts

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

9.02 Certificates

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

9.03 Replacement of Share Certificates

The board or any officer or agent designated by the board may in its or his discretion direct the issuance of a new share certificate or other such certificate in lieu of and upon cancellation of a certificate that has been mutilated or in substitution for a certificate claimed to have been lost, destroyed or wrongfully taken on payment of such reasonable fee and on such terms as to indemnity, reimbursement of expenses and evidence of loss and of title as the board may from time to time prescribe, whether generally or in any particular case.

9.04 Joint Holders

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

DIVISION TEN
TRANSFER OF SECURITIES

10.01 Registration of Transfer

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

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

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

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

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

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

            F. the transfer fee, if any, has been paid.

10.02       Transfer Agents and Registrar

            The board may from time to time by  resolution  appoint

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

10.03 Securities' Registers

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

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

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

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

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

10.04 Deceased Shareholders

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

DIVISION ELEVEN
DIVIDENDS AND RIGHTS

11.01 Dividends

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

11.02 Dividend Cheques

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

11.03 Non-Receipt of Cheques

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

11.04 Unclaimed Dividends

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

11.05 Record Date for Dividends and Rights

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

DIVISION TWELVE
INFORMATION AVAILABLE TO SHAREHOLDERS

12.01 Confidential Information

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

12.03 Registered Office and Separate Records Office

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

13.02 Notice to Joint Shareholders

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

13.03 Persons Entitled by Death or Operation of Law

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

             13.04       Non-Receipt of Notices

                         If a notice or  document  is sent to a  shareholder  in

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

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

DIVISION FOURTEEN
MISCELLANEOUS

14.01 Directors to Require Surrender of Share Certificates

The directors in office when a Certificate of Continuance is issued under the Act are hereby authorized to require the shareholders of the Corporation to surrender their share certificate, or such of their share certificates as the directors may determine, for the purpose of canceling the share certificates and replacing them with new share certificates that comply with section 49 of the Act, in particular, replacing existing share certificate with share certificates that are not negotiable securities under the Act.

The directors may take such proceedings as they deem necessary to compel any shareholder to comply with a requirement to surrender his share certificate or certificates pursuant to this section.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Ladies and Gentlemen:

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

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

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

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

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

BY TENDERING SERIES A NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, THE HOLDER IS DEEMED TO REPRESENT AND AGREE, AND HEREBY REPRESENTS AND AGREES, THAT (I) IT IS ACQUIRING EXCHANGE NOTES ISSUABLE IN EXCHANGE THEREFOR IN THE ORDINARY COURSE OF ITS BUSINESS, (II) UNLESS IT IS A BROKER-DEALER REFERRED TO IN THE NEXT SENTENCE, IT IS NOT ENGAGING AND DOES NOT INTEND TO ENGAGE IN THE DISTRIBUTION OF THE EXCHANGE NOTES, (III) AT THE TIME OF CONSUMMATION OF THE EXCHANGE OFFER THE HOLDER WILL HAVE NO ARRANGEMENT OR UNDERSTANDING WITH ANY PERSON TO PARTICIPATE IN THE DISTRIBUTION OF THE EXCHANGE NOTES IN VIOLATION OF THE PROVISIONS OF THE SECURITIES ACT, (IV) THE HOLDER IS NOT AN AFFILIATE OF ANY OF THE ISSUERS WITHIN THE MEANING OF RULE 405 UNDER THE SECURITIES ACT AND (V) IF IT PARTICIPATES IN THE EXCHANGE OFFER FOR THE PURPOSE OF DISTRIBUTING THE EXCHANGE NOTES IT MUST COMPLY WITH THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY RESALE OF THE EXCHANGE NOTES.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1. GUARANTEE OF SIGNATURES. Signatures on Letters of Transmittal need not be guaranteed, except as provided in this Instruction 1. In cases where Series A Notes are tendered for exchange by a registered holder of Series A Notes who has completed the box entitled "Special Delivery Instructions" on the Letter of Transmittal, signatures on Letters of Transmittal (or facsimiles thereof) must be guaranteed by a commercial bank or trust company having an office or correspondent in the United States or a firm which is a member of a registered national securities exchange or a member of the National Association of Securities Dealers, Inc. (an "Eligible Institution").

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

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

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

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

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

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

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

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

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

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

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

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

8. BACKUP FEDERAL INCOME TAX WITHHOLDING AND SUBSTITUTE FORM W9. Under the federal income tax laws, payments that may be made by the Issuers on account of Exchange Notes issued pursuant to the Exchange Offer may be subject to backup withholding at the rate of 31%. In order to avoid such backup withholding, each tendering holder should complete and sign the Substitute Form W-9 included in this Letter of Transmittal and either (a) provide the correct taxpayer identification number ("TIN") and certify, under penalties of perjury, that the TIN provided is correct and that (i) the holder has not been notified by the Internal Revenue Service (the "IRS") that the holder is subject to backup withholding as a result of failure to report all interest or dividends or (ii) the IRS has notified the holder that the holder is no longer subject to backup withholding; or (b) provide an adequate basis for exemption. If the tendering holder has not been issued a TIN and has applied for one, or intends to apply for one in the near future, such holder should write "Applied For" in the space provided for the TIN in

Part I of the Substitute Form W-9, sign and date the Substitute Form

W-9 and sign the Certificate of Payee Awaiting Taxpayer Identification Number. If "Applied For" is written in Part I, the Issuers (or the Paying Agent under the Indenture governing the Exchange Notes) shall retain 31% of payments made to the tendering holder during the sixty day period following the date of the Substitute Form W-9. If the holder furnishes the Exchange Agent or the Issuers with its TIN within sixty days after the date of the Substitute Form W-9, the Issuers (or the Paying Agent) shall remit such amounts retained during the sixty day period to the holder and no further amounts shall be retained or withheld from payments made to the holder thereafter. If, however, the holder has not provided the Exchange Agent or the Issuers with its TIN within such sixty day period, the Issuers (or the Paying Agent) shall remit such previously retained amounts to the IRS as backup withholding. In general, if a holder is an individual, the TIN is the Social Security number of such individual. If the Exchange Agent or the Issuers are not provided with the correct TIN, the holder may be subject to a $50 penalty imposed by the IRS. Certain holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, such holder must submit a statement (generally, IRS Form W-8), signed under penalties of perjury, attesting to that individual's exempt status. Such statements can be obtained from the Exchange Agent.

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

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

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

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

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

IMPORTANT TAX INFORMATION

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

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

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


PURPOSE OF SUBSTITUTE FORM W-9

To prevent backup withholding on payments made with respect to the Exchange Offer, the holder is required to provide the Exchange Agent with either: (i) the holder's correct TIN by completing the form below, certifying that the TIN provided on Substitute Form W-9 is correct (or that such holder is awaiting a TIN) and that (A) the holder has been notified by the Internal Revenue Service that the holder is subject to backup withholding as a result of failure to report all interest or dividends or (B) the Internal Revenue Service has notified the holder that the holder is no longer subject to backup withholding, or (ii) an adequate basis for exemption.

(Choose an allocation method under (e), (f). (g) or (h); (i) is mandatory if the Employer elects (f),
(g) or (h))

[X]      (e)  Nonintegrated  Allocation  Formula.  The Advisory  Committee  will
         allocate the annual  nonelective  contributions  in the same ratio that

         Compensation of all Participants for the Plan Year.

[N/A]    (f)  Two-Tiered  Integrated  Allocation  Formula -  Maximum  Disparity.
         First,  the Advisory  Committee  will  allocate the annual  nonelective
         contributions  in the same ratio that each  Participant's  Compensation
         plus  Excess  Compensation  for  the  Plan  Year  bears  to  the  total

         Year.  The  allocation  under this  paragraph,  as a percentage of each
         Participant's  Compensation plus Excess  Compensation,  must not exceed
         the applicable percentage (5.7%, 5.4% or 4.3%) listed under the Maximum
         Disparity Table following Option (i).

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

[N/A]    (g) Three-Tiered  Integrated  Allocation  Formula.  First, the Advisory
         Committee  will allocate the annual  nonelective  contributions  in the
         same ratio that each Participant's Compensation for the Plan Year bears
         to the total  Compensation of all  Participants  for the Plan Year. The

         Compensation may not exceed the applicable  percentage  (5.7%,  5.4% or
         4.3%) listed under the Maximum Disparity Table following Option (i).

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

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

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

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

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

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

Abraxas Petroleum Corporation, a Nevada corporation (the "Company"), hereby formulates and adopts the following Director Stock Option Plan (the "Plan") for non-officer members of the Board of Directors of the Company who are not employees or officers of the Company.

1. Purpose.

The Abraxas Petroleum Corporation Director Stock Option Plan (the "Plan") is intended to promote the best interests of the Company and its stockholders by enabling the Company to attract and retain persons of exceptional ability as directors and by providing an incentive to directors of the Company in the form of an equity participation in the Company.

(a) "Code" means the Internal Revenue Code of 1986, as amended from time to time.

(e) "Exchange Act" means the Securities Exchange Act of 1934, as amended.

(f) "Exercise Price" means the price at which a share of Common Stock may be purchased by a particular Participant pursuant to the exercise of an Option, as determined in accordance with Section 8 hereof.

Such Option Agreement shall be subject to the provisions of the Plan (which shall be incorporated by reference therein) and shall be in substantially the form attached hereto as Exhibit A.

(h) "Option" means the right of a Participant to purchase shares of Common Stock in accordance with the terms of the Plan and the Option Agreement which does not qualify as an incentive stock option under Section 422 of the Code, at a fixed option price equal to no less than 100 percent of the Fair Market Value (as defined in Section 8 hereof) of the Common Stock on the date the Option is granted.

(i) "Participant" means any Eligible Participant who is a party to an Option Agreement.

3. Adoption and Administration of Plan.

The Plan shall become effective upon approval by the stockholders of the Company at the Annual Meeting of Stockholders held on May 16, 1996 or at any adjournments or postponements thereof. Upon such effectiveness, except as otherwise set forth herein, any action taken by the Board of Directors of the Company with respect to the implementation, interpretation or administration of the Plan shall be final, conclusive and binding including, without limitation, the grant of any Options pursuant to the Plan.

Such shares of Common Stock may be issued out of the authorized and unissued shares of Common Stock of the Company or out of shares of Common Stock held in the Company's treasury.

7. Grant, Exercise Rights and Termination of Options.

(a) An Eligible Participant shall have an Option, and shall thereby become and be a Participant, only upon the due execution by such Eligible Participant and the Company of an Option Agreement (in the form attached hereto as Exhibit A).

(b) An Option of a Participant may be exercised during the period such Option is in effect and as set forth herein and in the Option Agreement, and only if compliance with all applicable federal and state securities laws can be effected, and may be exercised only by (i) such Participant's completion, execution and delivery to the Company of a notice of exercise as supplied by the Company and (ii) the payment to the Company of the aggregate Exercise Price, as provided under Section 9 hereof, for the shares of Common Stock to be purchased pursuant to such exercise (as shall be specified by such Participant in such notice) in accordance with the terms of the Plan and the Option Agreement. Except as specifically provided by a duly executed Option Agreement or unless waived by the Board of Directors of the Company, an Option or any of the rights thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law, except by will or the laws of descent and distribution.

(c) Notwithstanding any terms or provisions of the Plan to the contrary, the Board of Directors of the Company may delegate to the appropriate officer or officers of the Company the authority to prepare, execute and deliver any Option Agreement reflecting any Option granted under the Plan; provided, however, that any such Option Agreement shall be consistent with the terms and conditions of the Plan.

(d) Subject to the provisions of Section 13 hereof, Options granted pursuant to the Plan shall become exercisable according to the following schedule: (i) 25% shall become exercisable on the first anniversary of the date of grant; (ii) 25% shall become exercisable on the second anniversary of the date of grant; (iii) 25% shall become exercisable on the third anniversary of the date of grant; and (iv) 25% shall become exercisable on the fourth anniversary of the date of grant; provided, however, that the Participant must be an Eligible Participant at each of the vesting dates and, except as otherwise set forth in the Option Agreement, no Options may be exercised after the expiration of ninety (90) days from the date a Participant ceases to be an Eligible Participant.

8. Purchase Price of Common Stock.

The Exercise Price of an Option shall be equal to one hundred percent (100%) of the Fair Market Value of the shares of Common Stock of the Company on the date that such Option shall be granted. The Fair Market Value of the shares of Common Stock of the Company shall be the closing price on any given date or, if no shares of the Common Stock are traded on such date, the most recent prior date on which shares of the Common Stock were traded, as quoted on the principal stock exchange on which the Common Stock has been listed, or if the Common Stock is not listed on an exchange, the NASDAQ National Market or the NASDAQ Small Cap Market or, if the Common Stock is not quoted on the NASDAQ Stock Market or the NASDAQ Small Cap Market, the average of the final bid and final asked prices for a share of the Common Stock in the over-the-counter market as reported by the National Quotation Bureau Incorporated (or any similar organization or agency succeeding to its functions of reporting prices) or if the Common Stock is no longer publicly traded, as determined by the Board of Directors in good faith.

9. Payment for Shares of Common Stock.

Payment by each Participant for the shares of Common Stock purchased hereunder shall be made in accordance with the terms of any Option Agreement executed by such Participant.

10. Costs and Expenses.

All costs and expenses with respect to the adoption, implementation, interpretation and administration of the Plan shall be borne by the Company; provided, however, that, except as otherwise specifically provided in the Plan or the applicable Option Agreement between the Company and a Participant, the Company shall not be obligated to pay any costs or expenses (including legal fees) incurred by any Participant in connection with any Option Agreement, the Plan or any Option or Common Stock held by any Participant.

11. No Prior Right of Award.

Nothing in the Plan shall be deemed to give any director of the Company, or his legal representatives or assigns, or any other person or entity claiming under or through him, any contract or other right to participate in the benefits of the Plan. Nothing in the Plan shall be construed as constituting a commitment, guarantee, agreement or understanding of any kind or nature that the Company shall continue to engage any individual (whether or not a Participant). The Plan shall not affect, in any way, the right of the Company to remove any director (whether or not a Participant) at any time and for any reason whatsoever. No change of a Participant's duties as a director of the Company shall result in a modification of the terms of any rights of such Participant under the Plan or any Option Agreement executed by such Participant.

12. Changes in Capital Structure.

If the outstanding shares of Common Stock shall be changed into or exchanged for a different number or kind of shares of stock or other securities or property of the Company or of another corporation (whether by reason of merger, consolidation, recapitalization, reclassification, split up, combination of shares or otherwise), or if the number of such shares of Common Stock shall be increased by a stock dividend or stock split, there shall be substituted for or added to each share of Common Stock theretofore reserved for the purposes of the Plan, whether or not such shares are at the time subject to outstanding Options, the number and kind of shares of stock or other securities or property into which each outstanding share of Common Stock shall be so changed or for which it shall be so exchanged, or to which each such share shall be entitled, as the case may be. Outstanding Options shall also be considered to be appropriately amended as to price and other terms as may be necessary or appropriate to reflect the foregoing events. If there shall be any other change in the number or kind of the outstanding shares of Common Stock, or of any stock or other securities or property into which such Common Stock shall have been changed, or for which it shall have been exchanged, and if the Board shall in its sole discretion determine that such change equitably requires an adjustment in the number or kind or price of the shares then reserved for the purposes of the Plan, or in any Options theretofore granted or which may be granted under the Plan, then such adjustment shall be made by the Board and shall be effective and binding for all purposes of the Plan. In making any such substitution or adjustment pursuant to this Section 12, fractional shares may be ignored.

The Board shall have the power, in the event of any merger or consolidation of the Company with or into any other corporation, or the merger or consolidation of any other corporation with or into the Company, to amend all outstanding Options to permit the exercise thereof in whole or in part at anytime, or from time to time, prior to the effective date of any such merger or consolidation (but not more than ten (10) years after the date of grant of any incentive stock option) and to terminate each such Option as of such effective date.

13. Acceleration; Change in Control. Unless expressly provided to the contrary in the Option Agreement:

(a) Upon the occurrence of a Change of Control (as hereinafter defined), Options shall automatically become fully vested and exercisable;

(b) Anything in this Plan to the contrary notwithstanding, no termination, amendment or modification of this Plan after the occurrence of a Change of Control shall in any manner adversely affect any Eligible Participant's rights under this Section 13 without the written consent of the Eligible Participant affected by such termination, amendment or modification.

(c) The term "Change of Control" shall mean the occurrence of any of the following events:

(i) any "person" or "group" (as such terms are used in Section 13(d) and 14(d) of the Exchange Act is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act as in effect on the date hereof, except that a person shall be deemed to be the "beneficial owner" of all shares that any such person has the right to acquire pursuant to any agreement or arrangement or upon exercise of conversion rights, warrants, options or otherwise, without regard to the sixty day period referred to in such Rule), directly or indirectly, of securities representing 20% or more of the combined voting power of the Company's then outstanding securities;

(ii) any person or group shall make a tender offer or an exchange offer for 20% or more of the combined voting power of the Company's then outstanding securities;

(iii) at any time during any period of two consecutive years, individuals who at the beginning of such period constituted the Board and any new directors, whose election by the Board or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds (2/3) of the Company directors then still in office who either were the Company directors at the beginning of the period or whose election or nomination for election was previously so approved ("Current Directors"), cease for any reason to constitute a majority thereof;

(iv) the Company shall consolidate, merge or exchange securities with any other entity and the stockholders of the Company immediately before the effective time of such transaction do not beneficially own, immediately after the effective time of such transaction, shares entitling such stockholders to a majority of all votes (without consideration of the rights of any class of stock entitled to elect directors by a separate class vote) to which all stockholders of the corporation issuing cash or securities in the consolidation, merger or share exchange would be entitled for the purpose of electing directors or where the Current Directors immediately after the effective time of the consolidation, merger or share exchange would not constitute a majority of the Board of Directors of the corporation issuing cash or securities in the consolidation, merger or share exchange; or

(v) any person or group acquires 50% or more of the Company's assets.

Notwithstanding the foregoing, however, a Change in Control shall not be deemed to occur merely by reason of an acquisition of Company securities by, or any consolidation, merger or exchange of securities with, any entity that, immediately prior to such acquisition, consolidation, merger or exchange of securities, was a "subsidiary", as such term is defined below. For these purposes, the term "subsidiary" means (a) any corporation of which 95% of the capital stock of such corporation is owned, directly or indirectly, by the Company and (b) any unincorporated entity in respect of which the Company has, directly or indirectly, an equivalent degree of ownership.

14. Amendment or Termination of Plan.

Except as otherwise provided herein, the Plan may be amended or terminated in whole or in part by the Board of Directors of the Company (in its sole discretion), but no such action shall adversely affect or alter any right or obligation with respect to any Option or Option Agreement then in effect, except to the extent that any such action shall be required or desirable (in the opinion of the Company or its counsel) in order to comply with any rule or regulation promulgated or proposed under the Code by the Internal Revenue Service. Notwithstanding anything else herein contained to the contrary, (a) stockholder approval shall be required for any amendment which will (i) increase the aggregate number of shares of Common Stock that may be issued and sold under the Plan, or (ii) change the designation of class of persons eligible to receive options; and (b) the provisions of the Plan relating to (i) the number of shares of Common Stock for which an option may be granted, (ii) the option price, (iii) the timing of the grant and vesting of an option, may not be amended more than once every six months, with the exception of amendments required to be made so that the Plan continues to comply with the Code, ERISA, or the regulations promulgated or proposed thereunder.

15. Burden and Benefit.

The terms and provisions of the Plan shall be binding upon, and shall inure to the benefit of, each Participant and such Participant's executors and administrators, estate, heirs and personal and legal representatives.

16. Gender.

The use of any gender hereunder shall be deemed to be or include the other genders and the use of the singular herein shall be deemed to be or include the plural (and vice versa), wherever appropriate.

17. Headings.

The headings and other captions contained in the Plan are for convenience and reference only and shall not be used in interpreting, construing or enforcing any of the provisions of the Plan.

(l) where requested by Abraxas, provide assistance in connection with arranging financing or production hedging in respect of the Assets including providing, or where appropriate to the circumstances, technical engineering and geological assistance, and providing financial analysis and general business advice on the terms and conditions of any such financing;

(m) subcontract to third parties, with the prior written consent of and on terms satisfactory to Abraxas, the responsibilities of the Manager hereunder;

(n) prepare and distribute to Abraxas all statements, reports, receipts, notices, and other papers as may be necessary, desirable or requested from time to time by Abraxas;

(o) file, or cause to be filed, all reports or other information required by any governmental authority with jurisdiction over the Assets; and

(p) do all other and further things necessary or desirable to operate the Assets for the benefit of Abraxas in accordance with good oil and gas industry practice.

2.2 Consultation

The Manager shall advise and consult with Abraxas from time to time as requested by Abraxas and in any event with regard to any material matters relating to the orderly development and operation of the Assets. For greater certainty, but without limiting the generality of the foregoing, the Manager shall consult with Abraxas before commencing, initiating or participating in any operation in respect of the Assets which has the possibility of causing material damage to the Assets (such damage to include such things as damaging the reserves so as to cause a loss of recoverability of reserves and environmental damage) or which is a novel operation or is a novel use of an operation which does not yet have general acceptance in the oil and gas industry unless required due to an emergency risking life or property.

2.3 Budget

The Manager shall on or prior to November 30 of each year prepare and furnish to Abraxas for approval, a budget, setting forth the expected production from its respective interests in the Assets and the expected operating and capital expenditures related to the Assets and containing such other matters as should properly be included in such an annual budget or as are requested by Abraxas.

2.4 Disposition of Proceeds; Reports; Limitation of Authority

Notwithstanding that Abraxas may be named in any land and Operating Agreements applicable to the Assets, Abraxas shall direct all third party operators of the Assets to pay proceeds owing to Abraxas to the Manager.

The Manager shall maintain a cash float (the "cash float") as may be agreed to by the Manager and Abraxas from time to time. The Manager may retain revenues from time to time to maintain the cash float balance.

Unless otherwise directed by Abraxas, the Manager shall distribute all net proceeds received by it in respect of the Assets, less the amounts necessary to maintain the cash float, on a monthly basis by the 15th day after the end of each month in which such proceeds were received by Manager, commencing December 15, 1996, together with a cash reconciliation and a report for the month immediately preceding such month describing operations in respect of the Assets for such preceding month, which report shall include an accounting of all revenues and expenses, a general description of operations carried out in respect of the Assets, a report on the sale price received for the production of Petroleum Substances from the Assets, any extraordinary events affecting the Assets, a description of any and all spills, leaks or discovery of environmental damage caused by or affecting the Assets, and any other information as may be requested by Abraxas from time to time.

The Manager shall promptly notify Abraxas when it discovers or is advised of any significant environmental damage or potential environmental damage affecting or caused by the Assets and shall, subject to consultation with Abraxas, take such action as it deems necessary or desirable to deal with such environmental damage in accordance with good oil and gas industry practice.

Notwithstanding anything contained herein, the Manager shall not be entitled to commit Abraxas to any expenditure for the account of Abraxas for any single operation the total estimated cost of which is in excess of $50,000 to the account of Abraxas other than operating costs incurred in the ordinary course of business, without the prior direction of Abraxas, unless required due to an emergency risking life or property.

Where cash calls are made by the Operator pursuant to the Operating Agreements, the Manager shall satisfy such cash calls out of the proceeds received by the Manager on account of Abraxas, and the cash float and to the extent the Manager does not have sufficient monies of Abraxas to satisfy the cash calls, the Manager shall timely notify Abraxas of the cash call and Abraxas shall deliver to the Manager the amount of the cash call within the time specified by the Manager in respect of such cash call. The Manager shall in no event be required to lend any money to Abraxas.

2.5 Standard of Care

In exercising its powers and discharging its duties under this agreement, the Manager shall act in a manner determined by it to be in Abraxas' best interest and shall exercise that degree of care, diligence and skill that a reasonably prudent advisor and manager in respect of petroleum and natural gas properties in Western Canada would exercise in comparable circumstances. It is acknowledged and understood by the parties hereto that the Manager may in its capacity as advisor and manager delegate specific aspects of its obligations hereunder to any corporation, firm, person or other entity, provided that such obligation shall not relieve the Manager of any of its obligations under this agreement.

2.6 Manager as Operator

Where the Manager is required to act as the Operator on behalf of Abraxas, it shall operate in accordance with the terms and conditions of the applicable Operating Agreements. In the event the Manager and Abraxas own 100% of the working interest in Assets not otherwise operated, the Operating Procedure shall apply to them and the Manager shall operate such assets in accordance with the Operating Procedure; provided that in the event there is a conflict between the Operating Procedure and this agreement, this agreement shall prevail.


2.7 Marketing of Petroleum Substances

Subject to terms of the applicable Operating Agreements, the Manager, unless Abraxas is taking produced Petroleum Substances in kind, shall market and dispose of all Petroleum Substances produced from the Assets on such terms and conditions as it shall determine satisfactory to it except where it is satisfied with the terms of sale by the third party operator in which case it shall supervise the marketing and disposition of the Petroleum Substances as conducted by the third party operator. Notwithstanding the foregoing, the Manager shall not enter into any sales contract without the written consent of Abraxas (i) for oil having a term in excess of one year unless such contract can be terminated on not greater than 60 days notice; and (ii) for natural gas with volumes, net to Abraxas, in excess of one million cubic feet per day having a term exceeding one year, unless the contract may be terminated by Abraxas at any time on not greater than one year's notice to the applicable purchaser.

2.8 Taking in Kind

Subject to terms of the applicable Operating Agreements, Abraxas shall have the right to take its share of the Petroleum Substances produced from the Assets in kind and separately dispose of same and if Abraxas chooses to do so, the Manager shall promptly supply Abraxas any and all information required to effectively market and dispose of Abraxas' share of Petroleum Substances.

ARTICLE 3
MANAGER'S FEES AND EXPENSES

3.1 Reimbursable Costs

Abraxas shall reimburse or pay the Manager for all reasonable costs and expenses paid or to be paid by the Manager properly attributable to Abraxas and paid directly to third parties by or on behalf of Abraxas including, without limitation, all costs and expenses relating to financial accounting, audits, bank consulting services, legal, engineering and geological consulting services, joint venture audits, land administration, insurance and those duties for which the Manager is obligated to arrange in clause 2.1 hereof. Where any services are requested by Abraxas for its sole benefit, Abraxas shall be solely responsible for such costs. The Manager shall not be entitled to contract out services with third parties without the written consent of Abraxas unless such services are not within the expertise of the Manager or are not services ordinarily conducted by the Manager, in which case the Manager will consult with and advise Abraxas of preferable third party service providers. Nothing herein shall be interpreted as requiring the Manager to expend its own funds on behalf of Abraxas.

3.2 General and Administration Sharing

It is the intention of the parties that Abraxas shall reimburse the Manager for that proportion of the Manager's general overhead attributable to its management expenses for the performance of its obligations hereunder (the "Administrative Cost Amount"), and no more. Abraxas shall pay to the Manager an estimated annual Administrative Cost Amount for the Manager's general overhead, as determined below, payable in equal monthly installments. The Administrative Cost Amount for each calendar year, or lesser period for any period in which the Manager provides services for less than a twelve (12) month period (such stub period or twelve (12) month period being referred to as a "Period") shall be, unless otherwise agreed by the Manager and Abraxas, that percentage of the general and administrative costs of the Manager (excluding, for greater certainty any corporate costs relating to its corporate existence, compliance with corporate and securities legislation, costs of financing, whether debt or equity, and costs of a similar nature) equivalent to that percentage that the gross revenues attributable to the Assets of Abraxas managed by the Manager are of the aggregate gross revenues of all assets managed by Cascade. On or before sixty (60) days following the commencement of any period, the Manager shall reasonably and in good faith estimate the Administrative Cost Amount for such period and notify Abraxas of such estimated Administrative Cost Amount. The estimated Administrative Cost Amount for the initial period shall be as determined by the Manager. For all subsequent periods, in the event Abraxas does not agree with the Manager's estimate and Abraxas and the Manager cannot agree on an estimated Administrative Cost Amount for a period, the estimated Administrative Cost Amount for such period shall be equal to the estimated Administrative Cost Amount for the previous period. If at any time during a period, the Manager or Abraxas determine that the estimated Administrative Cost Amount shall be materially incorrect as a result of an event, the Manager shall provide a new estimated Administrative Cost Amount and all subsequent monthly installments of such period shall be adjusted so that the aggregate of installments to the Manager shall equal "to the revised estimated Administrative Cost Amount". As soon as possible after the end of each period, but in no event no later than 140 days after the end of such period, the Manager shall cause its auditors to calculate the actual general administrative costs and the percentage allocated to the performance of its obligations hereunder calculated as set forth in this clause or as otherwise agreed by Abraxas and the Manager. Abraxas and the Manager shall make an adjustment based on the difference between the amount calculated by the auditor as the actual Administrative Cost Amount and the estimated Administrative Cost Amount for such period. For greater certainty, any fees received as overhead reimbursements under operating agreements shall be deducted from the Manager's general and administrative costs for the purpose of calculating the Administrative Cost Amount pursuant hereto.

ARTICLE 4
ACTIVITIES OF THE MANAGER

4.1 Other Activities

The parties hereto hereby acknowledge that the Manager is engaged in and will continue to engage in the oil and gas business in Canada and elsewhere. Accordingly, the Manager will divide its resources between its obligations under this agreement and other operations in which Abraxas will not have, or be entitled to, any interest. Such other operations will include the acquisition, disposition and exploitation of Canadian resource properties. The parties hereto consent to such activities and they agree that nothing herein shall prevent the Manager or any of its officers, directors or employees or any of its Affiliates from having other business interests or from engaging in any other business activities relating to Canadian resource property including the ownership thereof. In the event that the interests of the Manager are in conflict with those of Abraxas, the Manager shall notify Abraxas of such conflict and shall be obliged to make decisions acting in good faith, having regard to the best interests of such parties and in a manner that would not contravene the obligations of the Manager to Abraxas.

4.2 Additional Information

The parties hereto acknowledge that exploration and development activities on the Assets may have the incidental affect of providing additional information with respect to, or augmenting the value of, properties in which the Manager or its Affiliates have an interest and the parties hereto agree that neither the Manager nor its Affiliates shall be liable to account to any of them with respect to such activities or results, provided that the Manager shall not act in a manner that would contravene its obligations to Abraxas.

During the term of this agreement, the Manager shall:

(a) unless otherwise agreed, not commingle its own funds or the funds of any other persons with any funds held by it on behalf of Abraxas; and

(b) not "step-up" any cost by reason of transactions among Affiliates of the Manager and accordingly, all costs charged to Abraxas will be the lowest amount of costs incurred by the Manager or any Affiliate thereof.

4.4 No Liability for Advice

The Manager shall not be liable, answerable or accountable for any loss or damage resulting from the advice given by the Manager or the exercise by the Manager of a discretion or its refusal to exercise a discretion, provided that the Manager has acted in a faithful, diligent and honest manner and is not in breach of any of its obligations hereunder.

ARTICLE 5 INDEMNIFICATION OF MANAGER

5.1 Indemnification

The Manager and any person who, at the request of the Manager, is serving or shall have served as a director, officer or employee of the Manager shall be indemnified by Abraxas against all liabilities and expenses (including judgments, fines, penalties, amounts paid in settlement and counsel fees) arising from or related in any manner to this agreement, unless the liability or expenses (as described above) results from the willful misfeasance, bad faith or gross negligence of the Manager or its Affiliates.

5.1 Indemnification

NOTE

In answering any item in this Statement of Eligibility which relates to matters peculiarly within the knowledge of the obligors and its directors or officers, the trustee has relied upon information furnished to it by the obligors.

Item 2, may, however, be considered as correct unless amended by an amendment to this Form T-1.

Pursuant to General Instruction B, the trustee has responded to Items 1, 2 and 16 of this form since to the best knowledge of the trustee as indicated in Item 13, the obligors are not in default under any indenture under which the applicant is trustee.
