FORWARD-LOOKING INFORMATION

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

o Our high debt level
o Our ability to raise capital
o Economic and business conditions
o Our success in completing acquisitions or in development and exploration activities
o Prices for crude oil and natural gas; and
o Other factors discussed elsewhere in this document

PART I

Item 1. Business

General

Abraxas Petroleum Corporation is an independent energy company engaged primarily in the acquisition, exploration, exploitation and production of crude oil and natural gas. Since January 1, 1991, our principal means of growth has been through the acquisition and subsequent development and exploitation of producing properties and related assets. As a result of our historical acquisition activities, we believe we have a substantial inventory of low risk exploration and development opportunities, the development of which is critical to the maintenance and growth of our current production levels. We seek to complement our acquisition and development activities by selectively participating in exploration projects with experienced industry partners.

Our principal areas of operation are Texas and western Canada. At December 31, 2000, we owned interests in 1,200,778 gross acres (835,445 net acres) and operated properties accounting for 79% of our PV-10, affording us substantial control over the timing and incurrence of operating and capital expenditures. PV-10 means estimated future net revenue, discounted at a rate of 10% per annum, before income taxes and with no price or cost escalation or de-escalation in accordance with guidelines promulgated by the Securities and Exchange Commission. An Mcf is one thousand cubic feet of natural gas. MMcf is used to designate one million cubic feet of natural gas and Bcf refers to one billion cubic feet of natural gas. Mcfe means thousands of cubic feet of natural gas equivalents, using a conversion ratio of one barrel of crude oil to six Mcf of natural gas. MMcfe means millions of cubic feet of natural gas equivalents and Bcfe means billions of cubic feet of natural gas equivalents. Mmbtu means million British Thermal Units. The term Bbl means one barrel of crude oil and MBbls is used to designate one thousand barrels of crude oil.

At December 31, 2000, estimated total proved reserves of Abraxas, our wholly-owned subsidiary, Canadian Abraxas Petroleum Limited, and our 49%-owned subsidiary, Grey Wolf Exploration Inc., were 244.4 Bcfe with an aggregate PV-10 of $1.0 billion. As of December 31, 2000, we had net natural gas processing capacity of 120 MMcf per day through our 13 natural gas processing plants and compression facilities in Canada, giving us substantial control over our Canadian production and marketing activities.

Business Strategy

Our primary business objectives are to increase reserves, production and cash flow through the following:

o Improved Liquidity. Since January 1999, we have sought to improve our liquidity in order to allow us to meet our debt service requirements and to maintain and increase existing production.

o Our sale in March 1999 of 12.875% Senior Secured Notes due 2003 (the "First Lien Notes") allowed us to refinance our bank debt, meet our near-term debt service requirements and make limited crude oil and natural gas capital expenditures.

o In October 1999, we sold a dollar denominated production payment for $4.0 million relating to existing natural gas wells in the Edwards Trend in South Texas to a unit of Southern Energy, Inc. which is now known as Mirant Americas Energy Capital, L.P. and in 2000, we sold additional production payments for $6.4 million relating to additional natural gas wells in the Edwards Trend to Mirant. We have the ability to sell up to $50 million to Mirant for drilling opportunities in the Edwards Trend.

o In December 1999, Abraxas and our wholly-owned Canadian subsidiary, Canadian Abraxas Petroleum Limited, completed an Exchange Offer whereby we exchanged our new 11.5% Senior Secured Notes due 2004, Series A (the "Second Lien Notes"), common stock and contingent value rights for approximately 98.43% of our outstanding 11.5% Senior Notes due 2004, Series D (the "Old Notes"). The Exchange Offer reduced our long-term debt by approximately $76 million after expenses.

o We are continuing to rationalize our significant non-core Canadian assets to allow us to continue to grow while reducing our debt. We may sell non-core assets or seek partners to fund a portion of the exploration costs of undeveloped acreage and are considering other potential strategic alternatives.

o In March 2000, we sold our interest in certain crude oil and natural gas properties that we owned and operated in Wyoming. Simultaneously, a limited partnership of which one of our subsidiaries was the general partner, which we accounted for on the equity method of accounting, sold its interest in crude oil and natural gas properties in the same area. Our net proceeds from these transactions were approximately $34.0 million.

o In March 2001, we announced that we had engaged Credit Lyonnais Securities (USA) Inc. and CIBC World Markets Corp. to assist us in a review of alternative financial strategies. Under the terms of this engagement, we may restructure, refinance or recapitalize some or all of our existing debt and/or issue equity securities.

o Low Cost Operations. We seek to maintain low operating and G&A expenses per Mcfe by operating a majority of our producing properties and related assets and by maintaining a high rate of production on a per well basis. As a result of this strategy, we have achieved per unit operating and G&A expenses that compare favorably with similar companies.

o Exploitation of Existing Properties. We will allocate a portion of our operating cash flow to the exploitation of our producing properties. We believe that the proximity of our undeveloped reserves to existing production makes development of these properties less risky and more cost-effective than other drilling opportunities available to us. Given our high degree of operating control, the timing and incurrence of operating and capital expenditures is largely within our discretion. Our capital expenditure budget for 2001 for existing leaseholds is approximately $42.0 million including approximately $13.5 million for our horizontal drilling exploitation program. We currently have horizontal drilling or completion operations in West Texas, South Texas and Wyoming. We focus our horizontal drilling activities in deep wells containing known columns of hydrocarbons. We believe that this drilling method provides increased production at low incremental costs and very high rates of return.

5

o Producing Property Acquisitions. As cash flow permits, we intend to continue to acquire producing crude oil and natural gas properties that can increase cash flow, production and reserves through operational improvements and additional development. In January 2001, we announced that we were in discussions with our 49%-owned subsidiary, Grey Wolf Exploration Inc., concerning a stock for stock acquisition of the remaining 51% ownership of Grey Wolf. If we complete this acquisition as contemplated, we expect that the impact on us will include the streamlining of our Canadian operations, an increase in net asset values for our stockholders, and an accretive impact to stockholders on an earnings basis.

o Focused Exploration Activity. We may allocate a portion of our capital budget to the drilling of exploratory wells that have high reserve potential. We believe that by devoting a relatively small amount of capital to high impact, high risk projects while reserving the majority of our available capital for development projects, we can reduce drilling risks while still benefiting from the potential for significant reserve additions.

Markets and Customers

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

In order to manage our exposure to price risks in the marketing of our crude oil and natural gas, from time to time we have entered into fixed price delivery contracts, financial swaps and crude oil and natural gas futures contracts as hedging devices. To ensure a fixed price for future production, we may sell a futures contract and thereafter either (i) make physical delivery of crude oil or natural gas to comply with such contract or (ii) buy a matching futures contract to unwind our futures position and sell our production to a customer. These contracts may expose us to the risk of financial loss in certain circumstances, including instances where production is less than expected, our customers fail to purchase or deliver the contracted quantities of crude oil or natural gas, or a sudden, unexpected event materially impacts crude oil or natural gas prices. These contracts may also restrict our ability to benefit from unexpected increases in crude oil and natural gas prices. You should read the discussion under "Management's Discussion and Analysis of Financial Condition And Results of Operations -- Liquidity and Capital Resources," and "Quantitative and Qualitative Disclosures about Market Risk; Commodity Price Risk" for more information regarding our hedging activities.

Substantially all of our crude oil and natural gas is sold at current market prices under short-term contracts, as is customary in the industry. During the year ended December 31, 2000, two purchasers accounted for approximately 26% of our crude oil and natural gas sales. We believe that there are numerous other companies available to purchase our crude oil and natural gas and that the loss of one or both of these purchasers would not materially affect our ability to sell crude oil and natural gas. The prices we receive for the sale of our crude oil and natural gas are subject to our hedging activities. You should read the discussion under "Management's Discussion and Analysis of Financial Condition And Results of Operations -- Liquidity and Capital Resources" and "Quantitative and Qualitative Disclosures about Market Risk; Commodity Price Risk" for more information regarding our hedging activities.

Risk Factors

Our debt levels and our debt covenants may limit our ability to pursue business opportunities and to obtain additional financing. We have substantial indebtedness and debt service requirements. Our total debt and stockholders' deficit were $267.6 million and $6.5 million, respectively, as of December 31, 2000. We may incur additional indebtedness in the future in connection with acquiring, developing and exploiting producing properties, although our ability to incur additional indebtedness is substantially limited by the terms of the

6

First Lien Notes indenture and the Second Lien Notes indenture. You should read the discussions under the heading " "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources" and the Consolidated Financial Statements and the notes thereto included elsewhere in this annual report for more information regarding our indebtedness.

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

o A substantial amount of our cash flow from operations will be used to pay interest on the First Lien Notes, any outstanding Old Notes and the Second Lien Notes;

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

o Our debt level may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, interest payments, scheduled principal payments, general corporate purposes or other purposes; and

o The terms of the First Lien Notes indenture, the Old Notes indenture and the Second Lien Notes indenture will permit the holders of the First Lien Notes, any outstanding Old Notes and the Second Lien Notes to accelerate payments upon an event of default or a change of control.

Our high level of debt increases the risk that we may default on our debt obligations. Our ability to meet our debt obligations and to reduce our level of debt depends on our future performance which, in turn, depends on general economic conditions and financial, business and other factors many of which are beyond our control.

We have substantial capital requirements. We make and will continue to make substantial capital expenditures for the acquisition, exploitation, development, exploration and production of crude oil and natural gas. In the past, we have funded our operations primarily through cash flow from operations and borrowings under our bank credit facilities and other sources. Due to severely depressed crude oil and natural gas prices in 1999, our cash flow from operations was substantially reduced. We met our liquidity needs in 1999 through the sale of the First Lien Notes and the sale of the production payment to Mirant and the sale of certain non-core properties together with cash flow from operations. In 2000, we met our liquidity needs through cash flow from operations, the sale of additional non-core properties including those in Wyoming and further installments on the production payment with Mirant. We are examining certain alternative sources of long term capital including:

o restructuring, refinancing or recapitalizing our current indebtedness;

o selling equity securities; and

o selling additional non-core properties.

The availability of these sources of capital depend upon a number of factors, many of which are beyond our control such as general economic and financial market conditions and crude oil and natural gas prices.

Our ability to raise funds through additional indebtedness will be substantially limited by the terms of the indenture governing the First Lien Notes, the indenture governing the Old Notes and the indenture governing the Second Lien Notes, although many of the restrictive covenants contained in the indenture governing the Old Notes were eliminated in connection with the Exchange Offer.

The First Lien Notes indenture and the Second Lien Notes indenture restrict, among other things, our ability to:

o incur additional indebtedness;
o incur liens;
o pay dividends or make certain other restricted payments;

7

o consummate certain asset sales;
o enter into certain transactions with affiliates;
o merge or consolidate with any other person; or
o sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets.

Additionally, our ability to raise funds through additional indebtedness will be limited because substantially all of our crude oil and natural gas properties and natural gas processing facilities are subject to a first lien or floating charge for the benefit of the holders of the First Lien Notes and a second lien or floating charge for the benefit of the holders of the Second Lien Notes. Finally, our indentures also place restrictions on the use of proceeds from asset sales.

We believe that our improved cash flow from operations due to higher commodity prices and operating results, the sale of non-core properties and additional installments on the production payment with Mirant will provide us with sufficient capital for the next 12 months. However, if our production or commodity prices decrease or if our drilling activities cost more than we anticipate, we may not be able to execute our business plan without additional capital.

Crude oil and natural gas prices and their volatility could adversely affect our revenue, cash flows and profitability. Our revenue, profitability and future rate of growth depend substantially upon prevailing prices for crude oil and natural gas. Crude oil and natural gas prices fluctuate and prior to 2000 had declined significantly. Natural gas prices affect us more than crude oil prices since most of our production and reserves are natural gas. Prices also affect the amount of cash flow available for capital expenditures and our ability to borrow money or raise additional capital. For example in 1999 we reduced our capital expenditures budget because of lower crude oil and natural gas prices. In addition, we may have ceiling test writedowns when prices decline. Lower prices may also reduce the amount of crude oil and natural gas that we can produce economically.

We cannot predict future crude oil and natural gas prices. Factors that can cause price fluctuations include:

o changes in supply and demand for crude oil and natural gas;

o weather conditions;

o the price and availability of alternative fuels;

o political and economic conditions in oil producing countries, especially those in the Mideast; and

o overall economic conditions.

Hedging transactions may limit our potential gains. We entered into hedge agreements and other financial arrangements at various times to attempt to minimize the effect of crude oil and natural gas price fluctuations. We cannot assure you that such transactions will reduce risk or minimize the effect of any decline in crude oil or natural gas prices. Any substantial or extended decline in crude oil or natural gas prices would have a material adverse effect on our business and financial results. Hedging activities may limit the risk of declines in prices, but such arrangements may also limit additional revenues from price increases. In addition, such transactions may expose us to risks of financial loss under certain circumstances, such as:

o production is less than expected; or

o price differences between delivery points for our production and those in our hedging agreements increase.

In 2000, we experienced hedging losses of $20.2 million. At year end 2000, the fair value of future hedges was a liability of approximately $38 million, which we estimate will reduce cash flow by $27 million in 2001 and $11 million in 2002. To the extent that these hedge agreements require us to pay the counterparty, our revenue will be reduced. You should read the discussion under the heading "Management's Discussion and Analysis of Financial Condition and

8

Results of Operations-- Liquidity and Capital Resources - Hedging Activities" for more information regarding our hedging activities.

Lower crude oil and natural gas prices increase the risk of ceiling limitation writedowns. We use the full cost method to account for our crude oil and natural gas operations. Accordingly, we capitalize the cost to acquire, explore for and develop crude oil and natural gas properties. Under full cost accounting rules, the net capitalized cost of crude oil and natural gas properties may not exceed a "ceiling limit" which is based upon the present value of estimated future net cash flows from proved reserves, discounted at 10%, plus the lower of cost or fair market value of unproved properties. If net capitalized costs of crude oil and natural gas properties exceed the ceiling limit, we must charge the amount of the excess to earnings. This is called a "ceiling limitation writedown." This charge does not impact cash flow from operating activities, but does reduce our stockholders' equity. The risk that we will be required to write down the carrying value of crude oil and natural gas properties increases when crude oil and natural gas prices are low or volatile. In addition, writedowns may occur if we experience substantial downward adjustments to our estimated proved reserves or if purchasers cancel long-term contracts for our natural gas production. In 1999, we recorded a writedown of $19.1 million ($11.9 million after tax) as a result of a downward adjustment to our proved reserves in Canada. In 1998, we recorded a write down of $61 million as a result of low commodity prices. We cannot assure you that we will not experience additional ceiling limitation writedowns in the future.

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

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

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

The estimates of our reserves are based upon various assumptions about future production levels, prices and costs that may not prove to be correct over time. In particular, estimates of crude oil and natural gas reserves, future net revenue from proved reserves and the PV-10 thereof for the crude oil and natural gas properties described in this document are based on the assumption that future crude oil and natural gas prices remain the same as crude oil and natural gas prices at December 31, 2000. The sales prices as of such date used for purposes of such estimates were $25.73 per Bbl of crude oil, $30.63 per Bbl of NGLs and $9.21 per Mcf of natural gas. This compares with $24.88 per Bbl of crude oil, $14.79 per Bbl of NGLs and $2.11 per Mcf of natural gas as of December 31, 1999. It is also assumed that we will make future capital expenditures of approximately $55.5 million in the aggregate, which are necessary to develop and realize the value of proved undeveloped reserves on our properties. Any significant variance in actual results from these assumptions could also materially affect the estimated quantity and value of reserves set forth herein.

We have experienced recurring net losses. The Company has experienced losses in three of the last four years. Additionally in 2000 if the significant gain on the sale of partnership is excluded the Company would have experienced a net loss for the year.

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

Our ability to replace production with new reserves is highly dependent on acquisitions or successful development and exploration activities. The rate of production from crude oil and natural gas properties declines as reserves are depleted. Our proved reserves will decline as reserves are produced unless we acquire additional properties containing proved reserves, conduct successful exploration and development activities or, through engineering studies, identify additional behind-pipe zones or secondary recovery reserves. Our future crude oil and natural gas production is therefore highly dependent upon our level of success in acquiring or finding additional reserves. We cannot assure you that our exploration and development activities will result in increases in reserves. Our operations may be curtailed, delayed or cancelled if we lack necessary capital and by other factors, such as title problems, weather, compliance with governmental regulations, mechanical problems or shortages or delays in the delivery of equipment.

Our ability to continue to acquire producing properties or companies that own such properties assumes that major integrated oil companies and independent oil companies will continue to divest many of their crude oil and natural gas properties. We cannot assure you that such divestitures will continue or that we will be able to acquire such properties at acceptable prices or develop additional reserves in the future. In addition, under the terms of the First Lien Notes indenture, the Old Notes indenture and the Second Lien Notes indenture, our ability to obtain additional financing in the future for acquisitions and capital expenditures will be limited

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

o that no commercially productive crude oil or natural gas reservoirs will be found;
o that crude oil and natural gas drilling and production activities may be shortened, delayed or canceled; and
o that our ability to develop, produce and market our reserves may be limited by:
- title problems,
- weather conditions,
- compliance with governmental requirements, and
- mechanical difficulties or shortages or delays in the delivery of drilling rigs, work boats and other equipment.

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

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

We operate in a highly competitive industry which may adversely affect our operations. We operate in a highly competitive environment. Competition is particularly intense with respect to the acquisition of desirable undeveloped crude oil and natural gas properties. The principal competitive factors in the acquisition of such undeveloped crude oil and natural gas properties include the staff and data necessary to identify, investigate and purchase such properties, and the financial resources necessary to acquire and develop such properties. We compete with major and independent crude oil and natural gas companies for properties and the equipment and labor required to develop and operate such properties. Many of these competitors have financial and other resources substantially greater than ours.

The principal resources necessary for the exploration and production of crude oil and natural gas are leasehold prospects under which crude oil and natural gas reserves may be discovered, drilling rigs and related equipment to explore for such reserves and knowledgeable personnel to conduct all phases of crude oil and natural gas operations. We must compete for such resources with both major crude oil and natural gas companies and independent operators. Although we believe our current operating and financial resources are adequate to preclude any significant disruption of our operations in the immediate future we cannot assure you that such materials and resources will be available to us.

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

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

The marketability of our production depends largely upon the availability, proximity and capacity of natural gas gathering systems, pipelines and processing facilities. The marketability of our production depends in part upon processing facilities. Transportation space on such gathering systems and pipelines is occasionally limited and at times unavailable due to repairs or improvements being made to such facilities or due to such space being utilized by other companies with priority transportation agreements. Our access to transportation options can also be affected by U.S. federal and state and Canadian regulation of crude oil and gas production and transportation, general economic conditions, and changes in supply and demand. These factors and the availability of markets are beyond our control. If market factors dramatically change, the financial impact on us could be substantial and adversely affect our ability to produce and market crude oil and natural gas.

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

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

11

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

Shares eligible for future sale may depress our stock price. At March 22, 2001, we had 22,593,969 shares of common stock outstanding of which 2,688,558 shares were held by affiliates, 4,035,524 shares of common stock subject to outstanding options granted under certain stock option plans (of which 1,556,813 shares were vested at March 22, 2001) and 950,000 shares issuable upon exercise of warrants. In addition, as part of the Exchange Offer, we issued CVRs which entitled the holders thereof to receive up to a total of 105,408,978 shares of our common stock if the price of our common stock does not reach certain target prices. The target price on May 21, 2001 is $5.97. As of March 22, 2001, based on the Abraxas Common Stock market price, CVR holders would be entitled to receive approximately 3.3 million shares.

All of the shares of common stock held by affiliates are restricted or control securities under Rule 144 promulgated under the Securities Act of 1933, as amended (the "Securities Act"). The shares issuable pursuant to the CVRs are exempt from registration under the Securities Act. The shares of the common stock issuable upon exercise of the stock options have been registered under the Securities Act. The shares of the common stock issuable upon exercise of the warrants are subject to certain registration rights and, therefore, will be eligible for resale in the public market after a registration statement covering such shares has been declared effective. Sales of shares of common stock under Rule 144 or another exemption under the Securities Act or pursuant to a registration statement could have a material adverse effect on the price of the common stock and could impair our ability to raise additional capital through the sale of equity securities.

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

Anti-takeover provisions could make a third party acquisition of Abraxas difficult. Abraxas' articles of incorporation and by-laws provide for a classified board of directors, with each member serving a three-year term and eliminate the ability of stockholders to call special meetings or take action by written consent. Abraxas has also adopted a stockholder rights plan. Each of the provisions in the articles of incorporation and by-laws and the stockholder rights plan could make it more difficult for a third party to acquire Abraxas without the approval of Abraxas' board. In addition, the Nevada corporate statute also contains certain provisions which could make an acquisition by a third party more difficult

Use of our net operating loss carryforwards may be limited. At December 31, 2000, the Company had, subject to the limitation discussed below, $101,800,000 of net operating loss carryforwards for U.S. tax purposes. These loss carryforwards will expire from 2001 through 2020 if not utilized. At December 31, 2000, the Company had approximately $11,400,000 of net operating loss carryforwards for Canadian tax purposes. These carryforwards will expire from 2001 through 2020 if not utilized.

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 the U.S. net operating loss carryforwards generated prior to December 31, 1991 of $4,909,000 will be limited to approximately $235,000 per year.

12

During 1992, the Company acquired 100% of the common stock of an unrelated corporation. The use of net operating loss carryforwards of the acquired corporation of $257,000 acquired in the acquisition are limited to approximately $115,000 per year.

As a result of the issuance of additional shares of common stock for acquisitions and sales of common stock, an additional ownership change under
Section 382 occurred in October 1993. Accordingly, it is expected that the use of all U.S. net operating loss carryforwards generated through October 1993
(including those subject to the 1991 and 1992 ownership changes discussed above)
of $8,295,000 will be limited as described above and in the following paragraph.

An ownership change under Section 382 occurred in December 1999, following the issuance of additional shares, as described in Note 5 to the Consolidated Financial Statements. It is expected that the annual use of U.S. net operating loss carryforwards subject to this Section 382 limitation will be limited to approximately $363,000, subject to the lower limitations described above. Future changes in ownership may further limit the use of the Company's carryforwards.

The annual Section 382 limitation may be increased during any year, within 5 years of a change in ownership, in which built-in gains that existed on the date of the change in ownership are recognized.

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 $36,134,000 and $34,736,000 for deferred tax assets at December 31, 1999 and 2000, respectively.

Regulation of Crude Oil and Natural Gas Activities

The exploration, production and transportation of all types of hydrocarbons are subject to significant governmental regulations. Our operations are affected from time to time in varying degrees by political developments and federal, state, provincial and local laws and regulations. In particular, oil and gas production operations and economics are, or in the past have been, affected by industry specific 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 past, maximum selling prices for certain categories of crude oil, natural gas, condensate and NGLs in the United States were subject to significant federal regulation. At the present time, however, all sales of our crude oil, natural gas, condensate and NGLs produced in the United States under private contracts may be sold at market prices. Congress could, however, reenact price controls in the future. If controls that limit prices to below market rates are instituted, the Company's revenue would be adversely affected.

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

The provincial governments of Alberta, British Columbia and Saskatchewan also regulate the volume of natural gas that may be removed from these provinces for consumption elsewhere based on such factors as reserve availability, transportation arrangements and marketing considerations.

The North American Free Trade Agreement

On January 1, 1994, the North American Free Trade Agreement ("NAFTA") among the governments of the United States, Canada and Mexico became effective. In the

13

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. The Texas Railroad Commission has recently become the lead agency for Texas for coordinating permits governing Texas to Mexico cross border pipeline projects. The availability of selling gas into Mexico may substantially impact the interstate gas market on all producers in the coming years.

United States Natural Gas Regulation

Historically, the natural gas industry as a whole has been more heavily regulated than the crude oil or other liquid hydrocarbons market. Most regulations focused on transportation practices. In the recent past interstate pipeline companies in the United States generally acted as wholesale merchants by purchasing natural gas from producers and reselling the gas to local distribution companies and large end users. Commencing in late 1985, the Federal Energy Regulatory Commission (the "FERC") issued a series of orders that have had a major impact on interstate natural gas pipeline operations, services, and rates, and thus have significantly altered the marketing and price of natural gas. The FERC's key rule making action, Order No. 636 ("Order 636"), issued in April 1992, required each interstate pipeline to, among other things, "unbundle" its traditional bundled sales services and create and make available on an open and nondiscriminatory basis numerous constituent services (such as gathering services, storage services, firm and interruptible transportation services, and standby sales and gas balancing services), and to adopt a new ratemaking methodology to determine appropriate rates for those services. To the extent the pipeline company or its sales affiliate markets natural gas as a merchant, it does so pursuant to private contracts in direct competition with all of the sellers, such as us; however, pipeline companies and their affiliates were not required to remain "merchants" of natural gas, and most of the interstate pipeline companies have become "transporters only," although many have affiliated marketers. Order 636 and related FERC orders have resulted in increased competition within all phases of the natural gas industry. We do not believe that Order 636 and the related restructuring proceedings affect us any differently than other natural gas producers and marketers with which we compete.

Transportation pipeline availability and cost are major factors affecting the production and sale of natural gas. Our physical sales of natural gas are affected by the actual availability, terms and cost of pipeline transportation. The price and terms for access onto the pipeline transportation systems remain subject to extensive Federal regulation. Although Order 636 does not directly regulate our production and marketing activities, it does affect how buyers and sellers gain access to and use of the necessary transportation facilities and how we and our competitors sell natural gas in the marketplace. The courts have largely affirmed the significant features of Order No. 636 and the numerous related orders pertaining to individual pipelines, although some appeals remain pending and the FERC continues to review and modify its regulations regarding the transportation of natural gas. For example, the FERC has recently begun a broad review of its natural gas transportation regulations, including how its regulation operate in conjunction with state proposals for natural gas marketing restructuring and in the increasingly competitive marketplace for all post-wellhead services related to natural gas.

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

(1) a series of orders in individual pipeline proceedings articulating a policy of generally approving the voluntary divestiture of interstate pipeline owned gathering facilities by interstate pipelines to their affiliates (the so-called "spin down" of previously regulated gathering facilities to the pipeline's nonregulated affiliates).

(2) Order No. 497 involving the regulation of pipelines with marketing affiliates.

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

14

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

(5) issuance of Policy Statements regarding Alternate Rates and Negotiated Terms and Conditions of Service covering (a)the pricing of long-term pipeline transportation services by alternative rate mechanism options, including the pricing of interstate pipeline capacity utilizing market-based rates, incentive rates, or indexed rates, and (b) investigating of whether FERC should permit pipelines to negotiate the terms and conditions of service, in addition to rates of service.

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

Several of these initiatives are intended to enhance competition in natural gas markets, although some, such as "spin downs," may have the adverse effect of increasing the cost of doing business on some in the industry, including us, as a result of the geographic monopolization of those facilities by their new, unregulated owners. As to all of these FERC initiatives, the ongoing, or, in some instances, preliminary and evolving nature of these regulatory initiatives makes it impossible at this time to predict their ultimate impact on our business. However, we do not believe that these FERC initiatives will affect us any differently than other natural gas producers and marketers with which we compete.

Since Order 636, FERC decisions involving onshore facilities have been more liberal in their reliance upon traditional tests for determining what facilities are "gathering" and therefore exempt from federal regulatory control. In many instances, what was once classified as "transmission" may now be classified as "gathering." We ship certain of our natural gas through gathering facilities owned by others, including interstate pipelines, under existing long term contractual arrangements. Although these FERC decisions have created the potential for increasing the cost of shipping our gas on third party gathering facilities, our shipping activities have not been materially affected by these decisions.

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

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

State and Other Regulation

All of the jurisdictions in which we own producing crude oil and natural gas properties have statutory provisions regulating the exploration for and production of crude oil and natural gas, including provisions requiring permits for the drilling of wells and maintaining bonding requirements in order to drill or operate wells and provisions relating to the location of wells, the method of

15

drilling and casing wells, the surface use and restoration of properties upon which wells are drilled and the plugging and abandoning of wells. Our operations are also subject to various conservation laws and regulations. These include the regulation of the size of drilling and spacing units or proration units on an acreage basis and the density of wells which may be drilled and the unitization or pooling of crude oil and natural gas properties. In this regard, some states and provinces allow the forced pooling or integration of tracts to facilitate exploration while other states and provinces rely on voluntary pooling of lands and leases. In addition, state and provincial conservation laws establish maximum rates of production from crude oil and natural gas wells, generally prohibit the venting or flaring of natural gas and impose certain requirements regarding the ratability of production. Some states, such as Texas and Oklahoma, have, in recent years, reviewed and substantially revised methods previously used to make monthly determinations of allowable rates of production from fields and individual wells. The effect of these regulations is to limit the amounts of crude oil and natural gas we can produce from our wells, and to limit the number of wells or the location at which we can drill.

State and provincial regulation of gathering facilities generally includes various safety, environmental, and in some circumstances, non-discriminatory take requirements, but does not generally entail rate regulation. In the United States, natural gas gathering has received greater regulatory scrutiny at both the state and federal levels in the wake of the interstate pipeline restructuring under Order 636. For example, the Texas Railroad Commission enacted a Natural Gas Transportation Standards and Code of Conduct to provide regulatory support for the State's more active review of rates, services and practices associated with the gathering and transportation of gas by an entity that provides such services to others for a fee, in order to prohibit such entities from unduly discriminating in favor of their affiliates.

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

Canadian Royalty Matters

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

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

Regulations made pursuant to the Mines and Minerals Act (Alberta) provide various incentives for exploring and developing crude oil reserves in Alberta. Crude oil produced from horizontal extensions commenced at least five years after the well was originally spudded may qualify for a royalty reduction. A 24-month, 8,000 cubic metres exemption is available to production from a well that has not produced for a 12-month period, if resuming production after January 31, 1993. In addition, crude oil production from eligible new field and new pool wildcat wells and deeper pool test wells spudded or deepened after September 30, 1992, is entitled to a 12-month royalty exemption (to a maximum of CDN$1 million). Crude oil produced from low productivity wells, enhanced recovery schemes (such as injection wells) and experimental projects is also subject to royalty reductions.

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

16

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

In Alberta, a producer of crude oil or natural gas is entitled to credit against the royalties payable to the Crown by virtue of the Alberta Royalty Tax Credit ("ARTC") program. The ARTC program is based on a price-sensitive formula, and the ARTC rate currently varies between 75% for prices for crude oil at or below CDN $100 per cubic metre and 35% for prices above CDN $210 per cubic metre. The ARTC rate is currently applied to a maximum of CDN $2.0 million of Alberta Crown royalties payable for each producer or associated group of producers. Crown royalties on production from producing properties acquired from corporations claiming maximum entitlement to ARTC will generally not be eligible for ARTC. The rate is established quarterly based on average "par price", as determined by the Alberta Department of Energy for the previous quarterly period. On December 22, 1997, the Government of Alberta gave notice that they intended to review the ARTC program, but no amendments have yet been passed into law. The government of Alberta did pass a law that effective January 1, 2001, the ARTC would not be available to individuals or trusts and will not otherwise be available unless the maximum credit is greater than or equal to $10,000 in the taxation year.

Producers of oil and natural gas in British Columbia are also required to pay annual rental payments in respect of Crown leases and royalties and freehold production taxes in respect of oil and gas produced from Crown and freehold lands respectively. The amount payable as a royalty in respect of oil depends on the vintage of the oil (whether it was produced from a pool discovered before or after October 31, 1975) or a pool in which no well was completed on June 1, 1998), the quantity of oil produced in a month and the value of the oil. Oil produced from newly discovered pools may be exempt from the payment of a royalty for the first 36 months of production. The royalty payable on natural gas is determined by a sliding scale based on a reference price which is the greater of the amount obtained by the producer and at prescribed minimum price. Gas produced in association with oil has a minimum royalty of 8% while the royalty in respect of other gas may not be less than 15%.

Environmental Matters

Our operations are subject to numerous federal, state, provincial and local laws and regulations controlling the generation, use, storage, and discharge of materials into the environment or otherwise relating to the protection of the environment. These laws and regulations may require the acquisition of a permit or other authorization before construction or drilling commences; restrict the types, quantities, and concentrations of various substances that can be released into the environment in connection with drilling, production, and gas processing activities; suspend, limit or prohibit construction, drilling and other activities in certain lands lying within wilderness, wetlands, and other protected areas; require remedial measures to mitigate pollution from historical and on-going operations such as use of pits and plugging of abandoned wells; restrict injection of liquids into subsurface strata that may contaminate groundwater; and impose substantial liabilities for pollution resulting from our operations. Environmental permits required for our operations may be subject to revocation, modification, and renewal by issuing authorities. Governmental authorities have the power to enforce compliance with their regulations and permits, and violations are subject to injunction, civil fines, and even criminal penalties. Our management believes that we are in substantial compliance with current environmental laws and regulations, and that we will not be required to make material capital expenditures to comply with existing laws. Nevertheless, changes in existing environmental laws and regulations or interpretations thereof could have a significant impact on us as well as the oil and gas industry in general, and thus we are unable to predict the ultimate cost and effects of future changes in environmental laws and regulations.

17

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

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

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

Our Canadian operations are also subject to environmental regulation pursuant to local, provincial and federal legislation which generally require operations to be conducted in a safe and environmentally responsible manner. Canadian environmental legislation provides for restrictions and prohibitions relating to the discharge of air, soil and water pollutants and other substances produced in association with certain crude oil and natural gas industry operations, and environmental protection requirements, including certain conditions of approval and laws relating to storage, handling, transportation and disposal of materials or substances which may have an adverse effect on the environment. Environmental legislation can affect the location of wells and facilities and the extent to which exploration and development is permitted. In addition, legislation requires that well and facilities sites be abandoned and reclaimed to the satisfaction of provincial authorities. A breach of such legislation may result in the imposition of fines or issuance of clean-up orders.

Certain federal environmental laws that may affect us include the Canadian Environmental Assessment Act which ensures that the environmental effects of projects receive careful consideration prior to licenses or permits being

18

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

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

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

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

Title to Properties

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

Employees

As of March 22, 2001, we had 47 full-time employees in the United States, including 3 executive officers, 3 non-executive officers, 2 petroleum engineers, 1 geologist, 5 managers, 1 landman , 10 secretarial and clerical personnel and 22 field personnel. Additionally, we retain contract pumpers on a month-to-month basis. We retain independent geological and engineering consultants from time to time on a limited basis and expect to continue to do so in the future.

As of March 22, 2001, Grey Wolf had 42 full-time employees, including 2 executive officers, 2 non-executive officers, 4 petroleum engineers, 3 geologists, 1 geophysicist, 21 technical and clerical personnel and 9 field personnel.

Primary Operating Areas

Texas

Our U.S. operations are concentrated in South and West Texas with over 99% of the PV-10 of our U.S. crude oil and natural gas properties at December 31, 2000, located in those two regions. We operate 89% of our wells in Texas. Operations in South Texas are concentrated along the Edwards trend in Live Oak and Dewitt Counties and in the Frio/Vicksburg trend in San Patricio County. We own an average 79% working interest in 69 wells with average daily production of 514 net Bbls of crude oil and NGLs and 16,566 net Mcf of natural gas per day for the year ended December 31, 2000. As of December 31, 2000, we had estimated net proved reserves in South Texas of 52,881 Mmcfe (75% natural gas) with a PV-10 of $199.1 million, 79.3% of which was attributable to proved developed reserves. Our West Texas operations are concentrated along the deep Devonian/Ellenberger formations and shallow Cherry Canyon sandstones in Ward County, the Spraberry trend in Midland County and in the Sharon Ridge Clearfork Field in Scurry County. We own an average 77% working interest in 181 wells with average daily production of 824 net Bbls of crude oil and NGLs and 5,810 net Mcf of natural gas per day for the year ended December 31, 2000. As of December 31, 2000, we had estimated net proved reserves in West Texas of 97,089 Mmcfe (77% natural gas) with a PV 10 of $350.0 million, 27.6% of which was attributable to proved developed reserves. During 2000, we drilled a total of 11 new wells (10 net) in Texas with a 100% success rate.

Western Canada

We own producing properties in western Canada, consisting primarily of natural gas reserves and interests ranging from 10% to 100% in approximately 200 miles of natural gas gathering systems and 13 natural gas processing plants. As of December 31, 2000, Canadian Abraxas Petroleum Limited (" Canadian Abraxas") and Grey Wolf had estimated net proved reserves of 92,991 Mmcfe (82% natural gas) with a PV-10 of $455.0 million, 95.0% of which was attributable to proved developed reserves. For the year ended December 31, 2000, the Canadian properties produced an average of approximately 1,128 net Bbls of crude oil and NGL's per day and 31,691 net Mcf of natural gas per day. The natural gas processing plants had aggregate capacity of approximately 316 MMcf of natural gas per day (120 net MMcf). During 2000, we drilled a total of 16 new wells (13.39 net) in Canada with a 63% success rate.

Grey Wolf manages the operations of Canadian Abraxas pursuant to a management agreement between Canadian Abraxas and Grey Wolf. Under the management agreement, Canadian Abraxas reimburses Grey Wolf for reasonable costs or expenses attributable to Canadian Abraxas and for administrative expenses based upon the percentage that Canadian Abraxas' gross revenue bears to the total gross revenue of Canadian Abraxas and Grey Wolf. In 2000, Canadian Abraxas paid $2.5 million to Grey Wolf pursuant to this management agreement. Abraxas and Canadian Abraxas own approximately 49% of the outstanding capital stock of Grey Wolf. In January 2001, we announced that we were in discussions with Grey Wolf concerning a stock for stock acquisition of the remaining 51% ownership of Grey Wolf.

Exploratory and Developmental Acreage

Our principal crude oil and natural gas properties consist of non-producing and producing crude oil and natural gas leases, including reserves of crude oil and natural gas in place. The following table indicates our interest in developed and undeveloped acreage as of December 31, 2000:

(1) Developed acreage consists of acres spaced or assignable to productive wells.
(2) Undeveloped acreage is considered to be those leased acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and gas, regardless of whether or not such acreage contains proved reserves. (3) Gross acres refers to the number of acres in which we own a working interest.
(4) Net acres represents the number of acres attributable to an owner's proportionate working interest and/or royalty interest in a lease (e.g., a 50% working interest in a lease covering 320 acres is equivalent to 160 net acres).

(1) Productive wells are producing wells and wells capable of production.
(2) A gross well is a well in which we own an interest. The number of gross wells is the total number of wells in which we own an interest.
(3) A net well is deemed to exist when the sum of fractional ownership working interests in gross wells equals one. The number of net wells is the sum of our fractional working interest owned in gross wells.

Substantially all of our existing crude oil and natural gas properties are pledged to secure our indebtedness under the First Lien Notes and Second Lien Notes. You should read the discussion under the heading "Management's Discussion of Financial Condition and Results of Operations--Liquidity and Capital Resources" for more information regarding our indebtedness.

Reserves Information

The crude oil and natural gas reserves of Abraxas have been estimated as of January 1, 2001, January 1, 2000, and January 1, 1999, by DeGolyer and MacNaughton, of Dallas, Texas. The reserves of Canadian Abraxas and Grey Wolf as of January 1, 2001, January 1, 2000 and January 1, 1999 have been estimated by McDaniel and Associates Consultants Ltd. of Calgary, Alberta. Crude oil and natural gas reserves, and the estimates of the present value of future net revenues therefrom, were determined based on then current prices and costs. Reserve calculations involve the estimate of future net recoverable reserves of crude oil and natural gas and the timing and amount of future net revenues to be received therefrom. Such estimates are not precise and are based on assumptions regarding a variety of factors, many of which are variable and uncertain.

The following table sets forth certain information regarding estimates of our crude oil, natural gas liquids and natural gas reserves as of January 1, 2001, January 1, 2000 and January 1, 1999:

(4) Includes 343,941 Bbls of crude oil reserves; 2,448.6 Mbbls of natural gas liquids reserves and 25,810 Mmcf of natural gas reserves, attributable to the Wyoming properties which were sold in March 2000. These reserves were estimated internally.

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

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

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

22

The estimates of our reserves are based upon various assumptions about future production levels, prices and costs that may not prove to be correct over time. In particular, estimates of crude oil and natural gas reserves, future net revenue from proved reserves and the PV-10 thereof for the crude oil and natural gas properties described in this report are based on the assumption that future crude oil and natural gas prices remain the same as crude oil and natural gas prices at December 31, 2000. The average sales prices as of such date used for purposes of such estimates were $25.73 per Bbl of crude oil, $30.63 per Bbl of NGLs and $9.21 per Mcf of natural gas. It is also assumed that we will make future capital expenditures of approximately $55.5 million in the aggregate, which are necessary to develop and realize the value of proved undeveloped reserves on our properties. Any significant variance in actual results from these assumptions could also materially affect the estimated quantity and value of reserves set forth herein.

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

Item 7. Management's Discussion And Analysis Of Financial Condition And Results Of Operations

The following is a discussion of our consolidated financial condition, results of operations, liquidity and capital resources. This discussion should be read in conjunction with our Consolidated Financial Statements and the Notes thereto. See "Financial Statements."

General

We have incurred net losses in three of the last four years and there can be no assurance that operating income and net earnings will be achieved in future periods. Our revenues, profitability and future rate of growth are substantially dependent upon prevailing prices for crude oil and natural gas and the volumes of crude oil, natural gas and natural gas liquids we produce. Natural gas and crude oil prices weakened somewhat during 1997 and continued to decrease during 1998. Crude oil and natural gas prices increased somewhat in 1999 and increased substantially in 2000. In addition, because our proved reserves will decline as crude oil, natural gas and natural gas liquids are produced, unless we are successful in acquiring properties containing proved reserves or conduct successful exploration and development activities, our reserves and production will decrease. Our ability to acquire or find additional reserves in the near future will be dependent, in part, upon the amount of available funds for acquisition, exploitation, exploration and development projects. If crude oil and natural gas prices revert to depressed levels, or if our production levels decrease, our revenues, cash flow from operations and financial condition will be materially adversely affected.

Results of Operations

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

o the sales prices of crude oil, natural gas liquids and natural gas,
o the level of total sales volumes of crude oil, natural gas liquids and natural gas,
o the level of and interest rates on borrowings, and
o the level and success of exploration and development activity.

27

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

Comparison of Year Ended December 31, 2000 to Year Ended December 31, 1999

Operating Revenue. During the year ended December 31, 2000, operating revenue from crude oil, natural gas and natural gas liquids sales increased by $14.0 million from $59.0 million in 1999 to $73.0 million in 2000. This increase was primarily attributable to an increase in commodity prices. Increased prices contributed $26.5 million in additional revenue, which was offset by $12.5 million due to a decrease in production volumes. The decline in production was due to the disposition of certain non-core properties, primarily in Canada.

Natural gas liquids volumes declined from 376.5 MBbls in 1999 to 314.9 in 2000. Crude oil sales volumes declined from 777.9 MBbls in 1999 to 636.7 MBbls during 2000. Natural gas sales volumes decreased from 25.7 Bcf in 1999 to 20.0 Bcf in 2000. Production declines were primarily attributable to our disposition of non-core assets during 2000.

Average sales prices in 2000 net of hedging losses were:

o $18.69 per Bbl of crude oil,
o $22.42 per Bbl of natural gas liquids, and
o $2.71 per Mcf of natural gas.

Average sales prices in 1999 net of hedging losses were:

o $14.57 per Bbl of crude oil,
o $13.40 per Bbl of natural gas liquids, and
o $1.66 per Mcf of natural gas.

28

We also had natural gas processing revenue of $2.7 million in 2000 as compared to $4.2 million in 1999. The decline in processing revenue is due to a decrease in third party natural gas being processed. We are utilizing more of the plant capacity to process our own natural gas, leaving less capacity for third party processing.

Lease Operating Expense. Lease operating expense ("LOE") and natural gas processing costs increased by $0.8 million from $17.9 million for the year ended December 31, 1999 to $18.8 million for the same period of 2000. LOE on a per Mcfe basis for 2000 was $0.73 per Mcfe as compared to $0.55 per Mcfe in 1999. The increase was due primarily to a general increase in the cost of services and increased production taxes due to higher commodity prices in 2000 as compared to 1999. The increase in the per Mcfe cost is due to a decline in production volumes.

G&A Expense. General and administrative ("G&A") expense increased from $5.3 million for the year ended December 31, 1999 to $6.9 million for the year ended December 31, 2000. The increase in G&A was due to the loss of approximately $600,000 of overhead billed to a partnership, substantially all of the assets of which were sold in March 2000 and an increase in director compensation as a result of our restructuring in the fourth quarter of 1999. Our G&A expense on a per Mcfe basis increased from $0.16 in 1999 to $0.27 in 2000. The increase in the per Mcfe cost was due partly to lower production volumes in 2000 as compared to 1999.

G&A - Stock-based Compensation Expense. Effective July 1, 2000, the Financial Accounting Standards Board ("FASB") issued FIN 44, "Accounting for Certain Transactions Involving Stock Compensation", an interpretation of Accounting Principles Board Opinion No. ("APB") 25. Under the interpretation, certain modifications to fixed stock option awards which were made subsequent to December 15, 1998, and not exercised prior to July 1, 2000, require that the awards be accounted for as variable until they are exercised, forfeited, or expired. In March 1999, we amended the exercise price to $2.06 on all options with an existing exercise price greater than $2.06. We recognized approximately $2.8 million as stock-based compensation expense during 2000 related to these repricings.

DD&A Expense. Depreciation, depletion and amortization ("DD&A") expense increased by $1.1 million from $34.8 million for the year ended December 31, 1999 to $35.9 million for the year ended December 31, 2000. Our DD&A expense on a per Mcfe basis for 1999 was $1.07 per Mcfe as compared to $1.40 per Mcfe in 2000. The increase in DD&A is the result of higher finding costs in the later part of 1999 and 2000.

Interest Expense. Interest expense decreased by $5.9 million from $37.0 million to $31.1 million for the year ended December 31, 2000 compared to 1999. This decrease resulted from reduced debt levels during 2000 compared to 1999. The reduced debt level was the result of the exchange of approximately $269.7 million principal amount of our Old Notes for approximately $188.8 million principal of our Second Lien Notes, shares of our common stock and contingent value rights.

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

The risk that we will be required to writedown the carrying value of our oil and gas assets increases when oil and gas prices are depressed or volatile. In addition, writedowns may occur if we have substantial downward revisions in our estimated proved reserves or if purchasers or governmental action cause an

29

abrogation of, or if we voluntarily cancel, long-term contracts for our natural gas. For the year ended December 31, 1999, we recorded a writedown of $19.1 million, $11.9 million after tax, related to our Canadian properties. We cannot assure you that we will not experience additional writedowns in the future. Should commodity prices decline, a further writedown of the carrying value of our crude oil and natural gas properties may be required. See Note 17 of Notes to Consolidated Financial Statements.

Minority interest. Minority interest in the net income of our 49% owned subsidiary increased to $1.3 million in 2000 from $269,000 in 1999. This increase is due to improved profitability of our subsidiary as a result of improved commodity prices received in 2000 as compared to 1999.

Income taxes Income tax expense (benefit) increased from a benefit of $12.6 million for the year ended December 31, 1999 to expense of $3.7 million for the year ended December 31, 2000. The benefit for the year ended December 31, 1999 was primarily attributable to the ceiling limitation write down that occurred in that year.

Other. In March 2000, Abraxas Wamsutter L.P. ("Partnership") sold all of its interest in its crude oil and natural gas properties to a third party. Prior to the sale of these properties, effective January 1, 2000, the Company's equity investee share of oil and gas property cost, results of operations and amortization were not material to consolidated operations or financial position. As a result of the sale, the Company received approximately $34 million, which represented a proportional interest in the Partnership's proved properties.

In June 2000, the we retired $3.5 million of the Old Notes and $3.6 million of the Second Lien Notes at a discount of $1.7 million.

Comparison of Year Ended December 31, 1999 to Year Ended December 31, 1998

Operating Revenue. During the year ended December 31, 1999, operating revenue from crude oil, natural gas and natural gas liquids sales increased by $4.7 million from $54.3 million in 1998 to $59.0 million in 1999. This increase was primarily attributable to an increase in commodity prices. Increased prices contributed $8.1 million in additional revenue, which was offset by $3.4 million due to a decrease in production volumes.

Natural gas liquids volumes declined from 867.4 MBbls in 1998 to 376.5 in 1999. The decline in natural gas liquids was primarily a result of the sale of oil and gas producing properties in Wyoming in late 1998. The Wyoming properties contributed 440.6 MBbls of natural gas liquids in 1998. Also contributing to the decline in natural gas liquids volumes was the closing of two natural gas processing plants in South Texas, one in late 1998 and one in January 1999 and our decision to stop processing natural gas in early 1999 due to depressed prices. We resumed processing natural gas in April 1999 as prices improved and third party facilities became available. Crude oil sales volumes increased by 6.8% from 728.6 MBbls in 1998 to 777.9 MBbls during 1999. Natural gas sales volumes increased from 24.9 Bcf in 1998 to 25.7 Bcf in 1999. The increase in crude oil and natural gas sales volumes was attributable to increased production attributable to our ongoing development program on existing and acquired properties.

Average sales prices in 1999 net of hedging losses were:

o $14.57 per Bbl of crude oil,

o $13.40 per Bbl of natural gas liquids, and

o $1.66 per Mcf of natural gas.

Average sales prices in 1998 including of hedging gains were:

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

We also had gas processing revenue of $4.2 million in 1999 as compared to $3.2 million in 1998.

Lease Operating Expense. LOE and natural gas processing costs decreased by $0.2 million from $18.1 million for the year ended December 31, 1998 to $17.9 million for the same period of 1999. LOE on a per Mcfe basis for 1999 was $0.55 per Mcfe as compared to $0.52 per Mcfe in 1998. The increase in the per Mcfe LOE is due to the sale of low cost natural gas wells in Wyoming which were replaced with higher cost crude oil wells acquired in Canada with the acquisition of New Cache Petroleums, Ltd. in January 1999.

G&A Expense. G&A expense decreased from $5.5 million for the year ended December 31, 1998 to $5.3 million for the year ended December 31, 1999. This is primarily a result of cost control measures implemented in the climate of depressed prices. Our G&A expense on a per Mcfe basis was unchanged at $0.16 per Mcfe in 1999 and 1998.

DD&A Expense. DD&A expense increased by $3.6 million from $31.2 million for the year ended December 31, 1998 to $34.8 million for the year ended December 31, 1999. Our DD&A expense on a per Mcfe basis for 1999 was $1.07 per Mcfe as compared to $0.90 per Mcfe in 1998. The increase in DD&A is primarily the result of downward reserve revisions in 1999, primarily related to Canadian operations.

Interest Expense. Interest expense increased by $6.0 million from $30.8 million to $36.8 million for the year ended December 31, 1999 compared to 1998. This increase was attributable to our increased borrowings during 1999. In March 1999, we issued $63.5 million in principal amount of the First Lien Notes . In December 1999, we consummated the Exchange Offer whereby $188.8 million in Second Lien Notes, 16,078,990 shares of our common stock, and 16,078,990 CVRs were exchanged for $269.7 million of the Old Notes. Long-term debt decreased from $299.7 million at December 31, 1998 to $273.4 million at December 31, 1999.

Ceiling Limitation Writedown. For the year ended December 31, 1999, we recorded a writedown of $19.1 million, $11.9 million after tax, related to our Canadian properties. For the year ended December 31, 1998 we recorded a writedown of $61 million related to our United States operations, We cannot assure you that we will not experience additional writedowns in the future. Should commodity prices decline, a further writedown of the carrying value of our crude oil and natural gas properties may be required. See Note 17 of Notes to Consolidated Financial Statements.

Minority interest. Minority interest in the net income of our 49% owned subsidiary increased to $269,000 in 1999 from $4,000 in 19998. This increase is due to improved profitability of our subsidiary.

Income taxes. Income tax expense (benefit) increased to a benefit of $12.6 million for the year ended December 31, 1999 from a benefit of $4.2 million in 1998. The increase in the benefit in 1999 was primarily attributable to the ceiling limitation write down that occurred in 1999.

Liquidity and Capital Resources

General. Capital expenditures in 1998, 1999 and 2000 were $57.9 million, $128.7 million and $74.4 million, respectively. The table below sets forth the components of these capital expenditures on a historical basis for the three years ended December 31, 1998, 1999 and 2000.

(1) Acquisition cost includes 71,063 shares of Abraxas common stock valued at approximately $449,000 in 1998 related to the acquisition of certain crude oil and natural gas properties.

31

During 2000, expenditures were primarily for the development of existing properties. In 1999, expenditures were primarily the acquisition of New Cache Petroleums, Ltd. In 1998, expenditures were primarily for the development of existing properties. These expenditures were funded through internally generated cash flow, the issuance of $275.0 million of the Old Notes and $63.5 million of the First Lien Notes, borrowings under a credit facility and the sale of non-core assets.

At December 31, 2000, we had current assets of $24.3 million and current liabilities of $38.1 million resulting in a working capital deficit of $13.8 million. The material components of our current liabilities at December 31, 2000, included trade accounts payable of $22.7 million, revenues due third parties of $6.3 million and accrued interest of $6.1 million. Stockholders' equity increased from a deficit of $9.5 million at December 31, 1999, to a deficit of $6.5 million at December 31, 2000.

Our current budget for capital expenditures for 2001 other than acquisition expenditures is $42.0 million, approximately $11.0 million of which has been spent to date. The remaining portion of such expenditures is largely discretionary and will be made primarily for the development of existing properties. Additional capital expenditures may be made for acquisition of producing properties if such opportunities arise, but we currently have no agreements, arrangements or undertakings regarding any material acquisitions. We have no material long-term capital commitments and are consequently able to adjust the level of our expenditures as circumstances dictate. Additionally, the level of capital expenditures will vary during future periods depending on market conditions and other related economic factors. Should the prices of crude oil and natural gas decline, our cash flows will decrease which may result in a further reduction of the capital expenditures budget.

Operating activities for the year ended December 31, 2000, provided us $21.4 million of cash. Investing activities used $18.8 million during 2000 comprised of $34.5 million provided from the sale of an equity investment in Wamsutter Holdings LP, $21.2 million provided from the sale of non-core properties and $74.4 million of used primarily for the acquisition and development of producing properties. Financing activities used $3.8 million during 2000.

Operating activities for the year ended December 31, 1999, provided us $3.9 million of cash. Investing activities used $111.2 million during 1999, comprised of $17.5 million provided from the sale of oil and gas producing properties and $128.7 million used primarily for the acquisition and development of producing properties. Financing provided $49.1 million during 1999.

Operating activities for the year ended December 31, 1998, provided $4.8 million of cash to us. Investing activities provided $2.0 million in 1998, comprised of $59.4 million provided from the sale of oil and gas producing properties, primarily the Wyoming Properties, and $57.4 million used primarily for the acquisition and development of producing properties. Financing provided $52.5 million during 1998.

We are heavily dependent on crude oil and natural gas prices which have historically been volatile. Although we have hedged a portion of our natural gas production and substantially all of our crude oil production and may continue this practice, future crude oil and natural gas price declines would have a material adverse effect on our overall results, and therefore, our liquidity. Furthermore, low crude oil and natural gas prices could affect our ability to raise capital on terms favorable to us.

Current Liquidity Needs. Since January 1999, we have sought to improve our liquidity in order to allow us to meet our debt service requirements and to maintain and increase existing production.

Our sale in March 1999 of our First Lien Notes allowed us to refinance our bank debt, meet our near-term debt service requirements and make limited crude oil and natural gas capital expenditures.

In October 1999, we sold a dollar denominated production payment for $4.0 million relating to existing natural gas wells in the Edwards Trend in South Texas to a unit of Mirant and during 2000, we sold additional production payments for $6.4 million relating to additional natural gas wells in the Edwards Trend to Mirant. We have the ability to sell up to $50 million to Mirant for drilling opportunities in the Edwards Trend.

32

In December 1999, Abraxas and our wholly-owned Canadian subsidiary, Canadian Abraxas Petroleum Limited, completed an Exchange Offer whereby we exchanged the Second Lien Notes, common stock, and contingent value rights for approximately 98.43% of our outstanding Old Notes. The Exchange Offer reduced our long term debt by $76 million net of fees and expenses.

We are continuing to rationalize our significant non-core Canadian assets to allow us to continue to grow while reducing our debt. We may sell non-core assets or seek partners to fund a portion of the exploration costs of undeveloped acreage and are considering other potential strategic alternatives.

In March 2000, we sold our interest in certain crude oil and natural gas properties that we owned and operated in Wyoming. Simultaneously, a limited partnership of which one of our subsidiaries was the general partner, accounted for on the equity method of accounting sold its interest in crude oil and natural gas properties in the same area. Our net proceeds from these transactions were approximately $34.0 million.

In March 2001, we announced that we had engaged Credit Lyonnais Securities (USA) Inc. and CIBC World Markets Corp. to assist us in a review of alternative financial strategies. Under the terms of this engagement, we may restructure, refinance or recapitalize some or all of our existing debt and/or issue equity securities.

We will have three principal sources of liquidity going forward: (i) cash on hand, (ii) cash flow from operations, and (iii) the production payment with Mirant. We also intend to continue to sell certain non-core properties, although the terms of the First Lien Notes indenture, the Second Lien Notes indenture and the Old Notes indenture substantially limit our use of proceeds from such sales.

We expect that the significantly improved commodity prices realized by us compared to those received in 1998 and 1999 and the expiration of a significant portion of the crude oil and natural gas hedges that we had put in place in earlier years will improve our liquidity position in 2001. Should commodity prices fall, all of our capital expenditures are discretionary and can be delayed to maintain liquidity. While the availability of capital resources cannot be predicted with certainty and is dependent upon a number of factors including factors outside of management's control, management believes that the net cash flow from operations plus cash on hand, cash available under the production payment and the proceeds from the sale of additional non-core properties will be adequate to fund operations and planned capital expenditures.

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

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

In March 1998, we entered into a costless collar hedge agreement with Enron Capital and Trade Resources Corp. for 2,000 Bbls of crude oil per day with a floor price of $14.00 per Bbl and a ceiling price of $22.30 per Bbl for crude oil on the NYMEX. The agreement was effective April 1, 1998 and extended through March 31, 1999. Under the terms of the agreement, we were paid when the average monthly price for crude oil on the NYMEX is below the floor price and paid the counterparty when the average monthly price exceeded the ceiling price. During the year ended December 31, 1999, we realized a loss of $1.8 million on this agreement, which is accounted for in crude oil and natural gas revenue.

33

We also entered into a hedge agreement with Barrett Resources Corporation ("Barrett") for the period November 1999 through October 2000. This agreement was for 1,000 Bbls per day with us being paid $20.30 and an additional 1,000 barrels per day with a floor price of $18.00 per barrel and a ceiling of $22.00 per Bbl. We realized losses from hedges of $ 20.2 million for the year ended December 31, 2000 which is accounted for in crude oil and natural gas revenue.

At year end 2000, Barrett had a swap call on either 1,000 Bbls of crude oil or 20,000 MMBtu of natural gas per day at Barrett's option at fixed prices ($18.00 for crude oil or $2.95 to $2.60 for natural gas) through October 31, 2002. As of December 31, 2000, the fair market value of the remaining fixed price hedge agreement was a liability of approximately $38 million, of which $27 million is expected to be charged to revenues in 2001 and $11 million in 2002.

Long-Term Indebtedness

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

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

Year                                                    Percentage

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

The Old Notes are joint and several obligations of Abraxas and Canadian Abraxas and rank pari passu in right of payment to all existing and future unsubordinated indebtedness of Abraxas and Canadian Abraxas. The Old Notes rank senior in right of payment to all future subordinated indebtedness of Abraxas and Canadian Abraxas. The Old Notes are, however, effectively subordinated to the First Lien Notes to the extent of the value of the collateral securing the First Lien Notes and the Second Lien Notes to the extent of the value of the collateral securing the Second Lien Notes. The Old Notes are unconditionally guaranteed, on a senior basis by a wholly-owned Abraxas subsidiary, Sandia Oil & Gas Corporation. The guarantee is a general unsecured obligation of Sandia and ranks pari passu in right of payment to all unsubordinated indebtedness of Sandia and senior in right of payment to all subordinated indebtedness of Sandia. The guarantee is effectively subordinated to the First Lien Notes and the Second Lien Notes to the extent of the value of the collateral securing these obligations.

Upon a change of control, as defined in the Old Notes Indenture, each holder of the Old Notes will have the right to require Abraxas and Canadian Abraxas to repurchase all or a portion of such holder's Old Notes at a redemption price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of repurchase. In addition, Abraxas and Canadian Abraxas will be obligated to offer to repurchase the Old Notes at 100% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase in the event of certain asset sales.

First Lien Notes. In March 1999, Abraxas consummated the sale of $63.5 million of the First Lien Notes. Interest on the First Lien Notes is payable semi-annually in arrears on March 15 and September 15, commencing September 15,

34

1999. The First Lien Notes are redeemable, in whole or in part, at the option of Abraxas on or after March 15, 2001, at the redemption prices set forth below, plus accrued and unpaid interest to the date of redemption, if redeemed during the 12-month period commencing on March 15 of the years set forth below:

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

The First Lien Notes are senior indebtedness of Abraxas secured by a first lien or charge on substantially all of the crude oil and natural gas properties of Abraxas and the shares of Grey Wolf owned by Abraxas. The First Lien Notes are unconditionally guaranteed on a senior basis, jointly and severally, by Canadian Abraxas, Sandia and one of our wholly-owned subsidiaries, Wamsutter Holdings, Inc.. The guarantees are secured by substantially all of the crude oil and natural gas properties of the guarantors and the shares of Grey Wolf owned by Canadian Abraxas.

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

The First Lien Notes indenture contains certain covenants that limit the ability of Abraxas and certain of its subsidiaries, including the guarantors of the First Lien Notes (the "Restricted Subsidiaries") to, among other things, incur additional indebtedness, pay dividends or make certain other restricted payments, consummate certain asset sales, enter into certain transactions with affiliates, incur liens, merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the assets of Abraxas.

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

(1) applicable law;

(2) the First Lien Notes indenture;

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

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

(5) agreements existing on the Issue Date (as defined in the First Lien Notes indenture) to the extent and in the manner such agreements were in effect on the Issue Date;

(6) customary restrictions with respect to subsidiaries of Abraxas pursuant to an agreement that has been entered into for the sale or disposition of capital stock or assets of such Restricted Subsidiary to be consummated in accordance with the terms of the First Lien Notes indenture or any Security Documents (as defined in the First Lien Notes indenture) solely in respect of the assets or capital stock to be sold or disposed of;

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

35

(8) an agreement governing indebtedness incurred to refinance the indebtedness issued, assumed or incurred pursuant to an agreement referred to in clause (2), (4) or (5) above; provided, however, that the provisions relating to such encumbrance or restriction contained in any such refinancing indebtedness are no less favorable to the holders of the First Lien Notes in any material respect as determined by the Board of Directors of Abraxas in their reasonable and good faith judgment that the provisions relating to such encumbrance or restriction contained in the applicable agreement referred to in such clause
(2), (4) or (5) and do not extend to or cover any new or additional property or assets and, with respect to newly created liens, (A) such liens are expressly junior to the liens securing the First Lien Notes, (B) the refinancing results in an improvement on a pro forma basis in Abraxas' Consolidated EBITDA Coverage Ratio (as defined in the First Lien Notes indenture) and (C) the instruments creating such liens expressly subject the foreclosure rights of the holders of the refinanced indebtedness to a stand-still of not less than 179 days.

Second Lien Notes. In December 1999, Abraxas and Canadian Abraxas completed an Exchange Offer whereby $269,699,000 of the Old Notes were exchanged for $188,778,000 of the new Second Lien Notes. An additional $5,000,000 of the Second Lien Notes were issued in payment of fees and expenses. Interest on the Second Lien Notes is payable semi-annually in arrears on May 1 and November 1, commencing May 1, 2000. The Second Lien Notes are redeemable, in whole or in part, at the option of Abraxas and Canadian Abraxas on or after December 1, 2000, at the redemption prices set forth below, plus accrued and unpaid interest to the date of redemption, if redeemed during the 12-month period commencing on December 1 of the years set forth below:

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

The Second Lien Notes are senior indebtedness of Abraxas and Canadian Abraxas and are secured by a second lien on substantially all of the crude oil and natural gas properties of Abraxas and Canadian Abraxas and the shares of Grey Wolf owned by Abraxas and Canadian Abraxas. The Second Lien Notes are unconditionally guaranteed on a senior basis, jointly and severally, by Sandia and Wamsutter. The guarantees are secured by substantially all of the crude oil and natural gas properties of the guarantors. The Second Lien Notes are, however, effectively subordinated to the First Lien Notes and related guarantees to the extent the value of the collateral securing the Second Lien Notes and related guarantees and the First Lien Notes and related guarantees is insufficient to pay both the Second Lien Notes and the First Lien Notes.

Upon a change of control, as defined in Second Lien Notes Indenture, each holder of the Second Lien Notes will have the right to require Abraxas and Canadian Abraxas to repurchase such holder's Second Lien Notes at a redemption price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase. In addition, Abraxas and Canadian Abraxas will be obligated to offer to repurchase the Second Lien Notes at 100% of the principal amount thereof plus accrued and unpaid interest to the date of redemption in the event of certain asset sales.

The Second Lien Notes indenture contains certain covenants that limit the ability of Abraxas and Canadian Abraxas and certain of their subsidiaries, including the guarantors of the Second Lien Notes (the "Restricted Subsidiaries") to, among other things, incur additional indebtedness, pay dividends or make certain other restricted payments, consummate certain asset sales, enter into certain transactions with affiliates, incur liens, merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the assets of Abraxas or Canadian Abraxas.

The Second Lien Notes indenture provides, among other things, that Abraxas and Canadian Abraxas may not, and may not cause or permit the Restricted Subsidiaries, to, directly or indirectly, create or otherwise cause to permit to

36

exist or become effective any encumbrance or restriction on the ability of such subsidiary to pay dividends or make distributions on or in respect of its capital stock, make loans or advances or pay debts owed to Abraxas, Canadian Abraxas or any other Restricted Subsidiary, guarantee any indebtedness of Abraxas, Canadian Abraxas or any other Restricted Subsidiary or transfer any of its assets to Abraxas, Canadian Abraxas or any other Restricted Subsidiary except for such encumbrances or restrictions existing under or by reason of:

(1) applicable law;

(2) the Old Notes indenture, the First Lien Notes indenture, or the Second Lien Notes indenture;

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

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

(5) agreements existing on the Issue Date (as defined in the Second Lien Notes indenture) to the extent and in the manner such agreements were in effect on the Issue Date;

(6) customary restrictions with respect to subsidiaries of Abraxas and Canadian Abraxas pursuant to an agreement that has been entered into for the sale or disposition of capital stock or assets of such Restricted Subsidiary to be consummated in accordance with the terms of the Second Lien Notes solely in respect of the assets or capital stock to be sold or disposed of;

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

(2), (4) or (5).

Net Operating Loss Carryforwards. At December 31, 2000, the Company had, subject to the limitation discussed below, $101,800,000 of net operating loss carryforwards for U.S. tax purposes. These loss carryforwards will expire from 2001 through 2020 if not utilized. At December 31, 2000, the Company had approximately $11,400,000 of net operating loss carryforwards for Canadian tax purposes. These carryforwards will expire from 2001 through 2020 if not utilized.

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 the U.S. net operating loss carryforwards generated prior to December 31, 1991 of $4,909,000 will be limited to approximately $235,000 per year.

During 1992, the Company acquired 100% of the common stock of an unrelated corporation. The use of net operating loss carryforwards of the acquired corporation of $257,000 acquired in the acquisition are limited to approximately $115,000 per year.

As a result of the issuance of additional shares of common stock for acquisitions and sales of common stock, an additional ownership change under
Section 382 occurred in October 1993. Accordingly, it is expected that the use of all U.S. net operating loss carryforwards generated through October 1993
(including those subject to the 1991 and 1992 ownership changes discussed above)
of $8,295,000 will be limited as described above and in the following paragraph.

37

An ownership change under Section 382 occurred in December 1999, following the issuance of additional shares, as described in Note 5. It is expected that the annual use of U.S. net operating loss carryforwards subject to this Section 382 limitation will be limited to approximately $363,000, subject to the lower limitations described above. Future changes in ownership may further limit the use of the Company's carryforwards.

The annual Section 382 limitation may be increased during any year, within 5 years of a change in ownership, in which built-in gains that existed on the date of the change in ownership are recognized.

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 $36,134,000 and $34,763,000 for deferred tax assets at December 31, 1999 and 2000, respectively.

New Accounting Pronouncement

SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, is effective for the Company as of January 1, 2001. SFAS 133, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. All derivatives, whether designated in hedging relationships or not, will be required to be recorded on the balance sheet at fair value. If the derivative is designated a fair-value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated a cash-flow hedge, changes in the fair value of the derivative will be recorded in other comprehensive income (OCI) and will be recognized in the income statement when the hedged item affects earnings. SFAS 133 defines new requirements for designation and documentation of hedging relationships as well as ongoing effectiveness assessments in order to use hedge accounting. For a derivative that does not qualify as a hedge, changes in fair value will we recognized in earnings.

The Company expects that at January 1, 2001, it will record a liability of $38 million with the offsetting charge to OCI as a cumulative transition adjustment for derivatives designated as cash-flow hedges prior to adopting SFAS 133.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk; Commodity Price Risk

Commodity Price Risk

Our exposure to market risks rests primarily with the volatile nature of crude oil, natural gas and natural gas liquids prices. We manage crude oil and natural gas prices through the periodic use of commodity price hedging agreements. You should read the discussion under "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources" for more information regarding our hedging activities. Assuming the production levels we attained during the year ended December 31, 2000, a 10% decline in crude oil, natural gas and natural gas liquids prices would have reduced our operating revenue, cash flow and net income by approximately $7.3 million for the year.

Hedging Sensitivity

The fair value of our hedge instrument was determined based on NYMEX forward price quotes as of December 31, 2000. As of December 31, 2000, a commodity price increase of 10% would have resulted in an unfavorable change in the fair market value of our hedging instrument of $7.6 million and a commodity price decrease of 10% would have resulted in a favorable change in the fair value of our hedge instrument of $7.9 million.

The following table sets forth our hedge position as of December 31, 2000.

                  Time Period           Notional Quantities                 Price                 Fair Value

38

Interest rate risk

At December 31, 2000, substantially all of our long-term debt was at fixed interest rates from 11.5% to 12.875% and not subject to fluctuations in market rates.

Foreign currency

Our Canadian operations are measured in the local currency of Canada. As a result, our financial results are affected by changes in foreign currency exchange rates or weak economic conditions in the foreign markets. Canadian operations reported a pre-tax loss of $2.4 million for the year ended December 31, 2000. It is estimated that a 5% change in the value of the U.S. dollar to the Canadian dollar would have changed our net income by approximately $120,000. We do not maintain any derivative instruments to mitigate the exposure to translation risk. However, this does not preclude the adoption of specific hedging strategies in the future.

(b) The Board of Directors is hereby expressly granted authority to authorize from time to time, in accordance with law, the issue of one or more series of Preferred Stock and, with respect to any such series, to fix by resolution or resolutions the numbers, powers, designations, preferences and relative, participating, option or other special rights of such series and the qualifications, limitations or restrictions thereof including, but without limiting the generality of the foregoing, the following:

(i) entitling the holders thereof to cumulative, non-cumulative or partially cumulative dividends, or to no dividends;

(a) a written notice, in substantially the form of the Subscription Notice appearing at the end of this Warrant, of the Holder's election to exercise this Warrant;

(b) this Warrant; and

(c) a check payable to the Company in the amount of the Exercise Price per share of Warrant Stock.

Notwithstanding anything to the contrary set forth herein, the Holder may at any time exercise this Warrant for "Net Warrant Shares." The number of Net Warrant Shares shall equal [WS x (MP - EP)/MP] where "WS" is the aggregate number of Shares issuable upon exercise of this Warrant or the portion being exercised, "MP" is the Market Price of the Common Stock and "EP" is the Exercise Price then in effect.

2.3 Company's Procedure. The Company shall as promptly as practicable, and in any event within ten (10) days after receipt of the notice required under
Section 2.2, execute and deliver or cause to be executed and delivered one or more certificates representing the aggregate number of shares of Warrant Stock to which the Holder is entitled.

2.4 Name and Effective Date. The stock certificate(s) so delivered shall be issued in the name of the Holder or such other name as shall be designated in the Subscription Notice specified in Section 2.2. Such certificate(s) shall be deemed to have been issued and the Holder or any other Person so designated to be named therein shall be deemed for all purposes to have become a holder of record of such shares as of the date the Company actually receives the notice specified in Section 2.2.

2.5 Expenses. The Company shall pay all expenses, taxes, and other charges payable in connection with the preparation, issue, and delivery of such stock certificate(s), except that, in case such stock certificate(s) shall be registered in a name or names other than the name of the Holder of this Warrant, stock transfer taxes that are payable upon the issuance of such stock certificate(s) shall be paid by the Holder hereof.

Article 3

Transfer

3.1 Permitted Transfers. This Warrant shall be freely transferable, in whole or in part to any Affiliate of the Holder, subject to the limitations specified in Section 3.2. This Warrant shall not be transferable to any other Person except with the written consent of the Company, which consent shall not be unreasonably withheld, and subject to the limitations specified in Section 3.2.

3.2. Securities Laws. Neither this Warrant nor the Warrant Stock shall be transferable unless:

(a) either a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), is in effect covering this Warrant or the Warrant Stock, as the case may be, or the Company has received an opinion from the Company's counsel to the effect that such registration is not required, or the Holder has furnished to the Company an opinion of the Holder's counsel, which counsel shall be reasonably satisfactory to the Company, to the effect that such registration is not required; and

(b) the transfer complies with any applicable state securities laws.

In the event the Holder seeks an opinion as to transfer without registration from the Holder's counsel, the Company shall provide such factual information to the Holder's counsel as the Holder's counsel may reasonably request for the purpose of rendering such opinion and such counsel may rely on the accuracy and completeness of such information in rendering such opinion. Upon issuance at a time when the Common Stock is not publicly traded, the Warrant Stock will bear a legend describing the restrictions on transfer set forth in this Section 3.2.

3.3 Procedure. (a) The Holder of this Warrant, or of any warrant substituted therefor pursuant to the provisions of this Section 3.3, may, subject to the limitations set forth in Section 3.1, in person or by duly authorized attorney, surrender the same for exchange at the principal office of the Company and, within a reasonable time thereafter and without expense (other than transfer taxes, if any), receive in exchange therefor one or more duly executed warrants each evidencing the right to receive one share of Common Stock or such other number of shares as may be designated by the Holder at the time of surrender.

The Company and any agent of the Company may treat the Person in whose name a Warrant is registered as the owner of the Warrant for all purposes hereunder and neither the Company nor such agent shall be affected by notice to the contrary. The Company covenants and agrees to take and cause to be taken all action necessary to effect such registrations, transfers and exchanges.

4

(b) The Holder may transfer the Warrant on the books of the Company by surrendering to the Company:

(i) the Warrant;

(ii) a written assignment of the Warrant, in substantially the form of the Assignment appearing at the end of this Warrant, naming the assignee and duly executed by the Holder; and

(iii) funds sufficient to pay any stock transfer taxes payable upon the making of such transfer.

The Company shall thereupon execute and deliver a new Warrant in the name of the assignee specified in such instrument of assignment. Upon issuance of the new Warrant or Warrants, the Warrant surrendered for transfer shall be canceled by the Company.

3.4 Expenses. The Company shall pay all expenses, taxes (other than transfer taxes), and other charges payable in connection with the preparation, issue and delivery of any new Warrant under this Article 3.

Article 4

Adjustments

4.1 Stock Splits, Stock Dividends and Reverse Stock Splits. If at any time the Company shall subdivide (by reclassification, by the issuance of a Common Stock dividend on Common Stock, or otherwise) its outstanding shares of Common Stock into a greater number, the number of shares of Common Stock that may be purchased hereunder shall be increased proportionately and the Exercise Price per share of Warrant Stock shall be decreased proportionately as of the effective date of such action. The effective date of a stock dividend shall be the date on which the dividend is declared. Issuance of a Common Stock dividend shall be treated as a subdivision of the whole number of shares of Common Stock outstanding immediately before the record date for such dividend into a number of shares equal to such whole number of shares so outstanding plus the number of shares issued as a stock dividend. If at any time the Company shall combine (by reclassification or otherwise) its outstanding number of shares of Common Stock into a lesser number, the number of shares of Warrant Stock that may be purchased hereunder shall be reduced proportionately and the Exercise Price per share of Warrant Stock shall be increased proportionately as of the effective date of such action.

4.2 Reorganization and Reclassification. In case of any capital reorganization or any reclassification of the capital stock of the Company while this Warrant remains outstanding, the Holder of this Warrant shall thereafter be

5

entitled to purchase pursuant to this Warrant (in lieu of the kind and number of shares of Warrant Stock that the Holder would have been entitled to purchase or acquire immediately before such reorganization or reclassification) the kind and number of shares of stock of any class or classes or other securities or property for or into which such shares of Common Stock would have been exchanged, converted or reclassified if the Warrant Stock had been purchased immediately before such reorganization or reclassification at a total price not to exceed that payable upon the exercise of the unexercised portion of this Warrant. In case of any such reorganization or reclassification, appropriate provision (as determined by resolution of the Board of Directors of the Company) shall be made with respect to the rights and interests thereafter of the Holder of this Warrant, to the end that all the provisions of the Warrant (including adjustment provisions) shall thereafter be applicable, as nearly as reasonably practicable, in relation to such stock or other securities or property.

4.3 Statement of Adjustment of Warrant Stock. Whenever the number or kind of shares comprising Warrant Stock or the Exercise Price is adjusted pursuant to this Article 4, the Company shall promptly give notice to the Holder, stating that such an adjustment has been effected and setting forth the number and kind of shares purchasable and the amount of the then-current Exercise Price, and stating in reasonable detail the facts requiring such adjustment and the calculation of such adjustment.

4.6 No Other Adjustments. No adjustments in the number or kind or price of shares constituting Warrant Stock shall be made except as provided in this Article 4.

Article 5

Covenants of the Company

The Company covenants and agrees that:

5.1 Reservation of Shares. At all times, the Company will reserve and set apart and have, free from pre-emptive rights, a sufficient number of shares of authorized but unissued Common Stock or other securities, if applicable, to enable it at any time to fulfill all of its obligations hereunder.

5.2 Adjustment of Par Value. Before taking any action that would cause an adjustment reducing the Exercise Price per share below the then-current par value of the shares of Warrant Stock issuable upon exercise of the Warrant, the Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Warrant Stock at such adjusted price.

5.3 Notice of Significant Events. In case the Company proposes to:

6

(a) pay any dividend, payable in stock (of any class or classes) or in convertible securities, upon its Common Stock or to make any distribution (other than ordinary cash dividends) to the holders of its Common Stock;

(b) subdivide as a whole (by reclassification, by the issuance of a stock dividend on Common Stock, or otherwise) the number of shares of Common Stock then outstanding into a greater number of shares of Common Stock, with or without par value;

(c) effect any capital reorganization or reclassification of capital stock of the Company;

(d) consolidate with, or merge into, any other corporation or business or sell or convey its assets as an entirety or substantially as an entirety;

(e) effect the liquidation, dissolution, or winding up of the Company;

(f) make any other fundamental change in respect of which the Holder of this Warrant would have been entitled to vote, pursuant to the

corporation  law of the State of  Nevada,  if the  Warrant  had been  previously
exercised;

then the Company shall cause notice of any such  intended  action to be given to
the  Holder  (i) not less than  thirty  (30) days  before  the date on which the

transfer books of the Company shall close or a record be taken for such stock dividend or for determining rights to vote in respect of any fundamental change, including any capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or any other fundamental change, and (ii) not less than thirty (30) days before the effective date, in the case of any such capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or other fundamental change.

7

Article 6

Limitation of Liability

No provision of this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive dividends or to receive notice as a stockholder in respect of meetings of stockholders for the election of members of the Board of Directors of the Company or any other matter whatsoever as stockholders of the Company. In the absence of affirmative action by the Holder to purchase shares of Common Stock, no provision hereof shall give rise to any liability of the Holder for the purchase price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Article 7

Merger, Consolidation, or Change

7.1 Continuation of Warrant. Except as provided in Section 7.2, in the event that the Company proposes to consolidate with, or merge into, any other corporation or business or to transfer its property as an entirety or substantially as an entirety, or to effect the liquidation, dissolution, or winding up of the Company, or to change the Common Stock in any manner (other than to change its par value), then after the Company causes notice of such proposed action to be given to the Holder of record as provided in Section 5.3, the Holder shall be entitled, on or before the effective date of such merger, consolidation, transfer, liquidation, dissolution, winding up, or change to require the Company or the successor or purchasing entity, as the case may be, to (a) execute with the Holder an agreement providing that the Holder shall have the right thereafter and throughout the remaining term of the Warrant upon payment of the Exercise Price per share of Warrant Stock in effect immediately prior to such action to purchase with respect to each share of Warrant Stock issuable upon exercise of this Warrant the kind and amount of shares of stock and other securities, property (including cash) or any combination thereof which the Holder would have owned or have been entitled to receive after the happening of such consolidation, merger, sale, conveyance, or change had this Warrant been exercised with respect to such share of Warrant Stock immediately prior to such action and (b) make effective provision in its Articles of Incorporation or otherwise, if necessary, in order to effect such agreement. Such agreement shall provide for adjustments which shall be as nearly equivalent as practicable to the adjustments in Article 4 of this Warrant. The provisions of this Section 7.1 shall similarly apply to successive consolidations, mergers, sales, conveyances or changes.

7.2 Exception. Section 7.1 shall not apply to a consolidation or merger with a Person in which the Company is the surviving entity.

8.1 Piggyback Registration Rights. If, at any time on or before the expiration of this Warrant, the Company proposes to file a registration statement for the public sale of any of its Common Stock under the Securities Act, other than a registration statement originally declared effective prior to the date hereof or a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 under the Securities Act is applicable or pursuant to which Common Stock is registered other than for sale to the public, the Company shall, not later than thirty (30) days prior to the initial filing of the registration statement, deliver notice of its intent to file such registration statement to the Holder, setting forth the minimum and maximum proposed offering price, commissions, and discounts in connection with the offering, and other relevant information. Within ten (10) days after receipt of notice of the Company's intent to file a registration statement, the Holder shall be entitled to request that the Warrant Stock be included in such registration statement, and the Company will use its best efforts to cause such Warrant Stock to be included in the offering covered by such registration statement. In the event the Warrant Stock is included in the registration statement, the Holder may transfer the Warrant to an underwriter or broker for exercise by such underwriter or broker in connection with a distribution of the Warrant Stock.

8.2 Filing Obligations of the Company. In connection with any registration of the Warrant Stock effected under Section 8.1, the Company shall:

(b) furnish to the Holder such number of copies of any prospectus or offering circular, including a preliminary prospectus, and of a full registration statement and exhibits in conformity with the requirements of the Securities Act and rules and regulations thereunder, as the Holder may reasonably request in order to facilitate the disposition of such securities;

(c) use its best efforts to register or qualify the Warrant Stock covered by the registration statement, as the case may be, under the securities or blue sky laws of such jurisdictions as the Holder may reasonably request, and accomplish any and all other acts and things which may be necessary or advisable to permit sale in such jurisdictions of such Warrant Stock; provided, however, that the Company shall not be required to register as a dealer or to qualify as a foreign corporation in any such jurisdictions or to escrow any shares of its capital stock.

9

8.3 Expenses. All expenses incurred by the Company in connection with any registration of the Warrant Stock effected under Section 8.1, including, without limitation, all registration and filing fees, fees and expenses of complying with state securities and blue sky laws, printing expenses, fees and expenses of the Company's counsel and accountants and fees and expenses of counsel for the Holder, shall be paid by the Company; provided, however, that all underwriting discounts and selling commission applicable to the Warrant Stock shall not be borne by the Company but shall be borne by the Holder.

In connection with the filing of any registration statement and sales of Warrant Stock thereunder, the Company shall indemnify and hold harmless the Holder of this Warrant, any underwriter, and each other Person, if any, who controls the Holder or the underwriter within the meaning of the Securities Act, against losses, claims, damages or liabilities, joint or several (or actions in respect thereto) ("Losses"), to which any such Holder, underwriter, or controlling Person may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which the Warrant Stock was registered under the Securities Act, any preliminary prospectus, offering circular or final prospectus contained therein, or any amendment or supplement thereto, or any report filed with the Securities and Exchange Commission (the "Disclosure Documents"), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse any such Holder, underwriter, or controlling Person for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Company; provided, however, that the Company shall not be liable in any such case to the extent that any such Losses arise out of or omission or alleged omission made in such Disclosure Documents in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Holder of this Warrant for use specifically in connection with the preparation of such Disclosure Document.

(b) By the Holder. In connection with the filing of any registration statement and sales of the Warrant Stock thereunder, the Holder shall indemnify the Company, any underwriter, each of the Company's directors, each of its officers who signed such registration statement, and each other Person, if any, who controls the Company or the underwriter within the meaning of the Securities Act, against any Losses to which the Company, any of its directors, officers, or controlling Persons may become subject under the Securities Act or otherwise,

8.5 Discharge of Registration Obligations. In the event the Holder demands that the Warrant Stock be registered pursuant to Section 8.1 herein, the Company shall have the right to discharge the registration obligations set forth in Section 8.1 by repurchasing all or any part of the Warrant or Warrant Stock, as designated by the Holder, for cash at the Market Price determined as of the date the Holder demands registration or the date the Company delivers notice of its election to repurchase, whichever is higher. The Company must deliver written notice to the Holder of its election to repurchase the Warrant within thirty (30) days after receipt of a request by the Holder for registration. The Company shall deliver the purchase price to the Holder upon delivery of the Warrant or Warrant Stock.

(a) either a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), is in effect covering this Warrant or the Warrant Stock, as the case may be, or the Company has received an opinion from the Company's counsel to the effect that such registration is not required, or the Holder has furnished to the Company an opinion of the Holder's counsel, which counsel shall be reasonably satisfactory to the Company, to the effect that such registration is not required; and

(b) the transfer complies with any applicable state securities laws.

In the event the Holder seeks an opinion as to transfer without registration from the Holder's counsel, the Company shall provide such factual information to the Holder's counsel as the Holder's counsel may reasonably request for the purpose of rendering such opinion and such counsel may rely on the accuracy and completeness of such information in rendering such opinion. Upon issuance at a time when the Common Stock is not publicly traded, the Warrant Stock will bear a legend describing the restrictions on transfer set forth in this Section 3.2.

3.3 Procedure. (a) The Holder of this Warrant, or of any warrant substituted therefor pursuant to the provisions of this Section 3.3, may, subject to the limitations set forth in Section 3.1, in person or by duly authorized attorney, surrender the same for exchange at the principal office of the Company and, within a reasonable time thereafter and without expense (other than transfer taxes, if any), receive in exchange therefor one or more duly executed warrants each evidencing the right to receive one share of Common Stock or such other number of shares as may be designated by the Holder at the time of surrender.

The Company and any agent of the Company may treat the Person in whose name a Warrant is registered as the owner of the Warrant for all purposes hereunder and neither the Company nor such agent shall be affected by notice to the contrary. The Company covenants and agrees to take and cause to be taken all action necessary to effect such registrations, transfers and exchanges.

4

(b) The Holder may transfer the Warrant on the books of the Company by surrendering to the Company:

(i) the Warrant;

(ii) a written assignment of the Warrant, in substantially the form of the Assignment appearing at the end of this Warrant, naming the assignee and duly executed by the Holder; and

(iii) funds sufficient to pay any stock transfer taxes payable upon the making of such transfer.

The Company shall thereupon execute and deliver a new Warrant in the name of the assignee specified in such instrument of assignment. Upon issuance of the new Warrant or Warrants, the Warrant surrendered for transfer shall be canceled by the Company.

3.4 Expenses. The Company shall pay all expenses, taxes (other than transfer taxes), and other charges payable in connection with the preparation, issue and delivery of any new Warrant under this Article 3.

Article 4

Adjustments

4.1 Stock Splits, Stock Dividends and Reverse Stock Splits. If at any time the Company shall subdivide (by reclassification, by the issuance of a Common Stock dividend on Common Stock, or otherwise) its outstanding shares of Common Stock into a greater number, the number of shares of Common Stock that may be purchased hereunder shall be increased proportionately and the Exercise Price per share of Warrant Stock shall be decreased proportionately as of the effective date of such action. The effective date of a stock dividend shall be the date on which the dividend is declared. Issuance of a Common Stock dividend shall be treated as a subdivision of the whole number of shares of Common Stock outstanding immediately before the record date for such dividend into a number of shares equal to such whole number of shares so outstanding plus the number of shares issued as a stock dividend. If at any time the Company shall combine (by reclassification or otherwise) its outstanding number of shares of Common Stock into a lesser number, the number of shares of Warrant Stock that may be purchased hereunder shall be reduced proportionately and the Exercise Price per share of Warrant Stock shall be increased proportionately as of the effective date of such action.

4.2 Reorganization and Reclassification. In case of any capital reorganization or any reclassification of the capital stock of the Company while

5

this Warrant remains outstanding, the Holder of this Warrant shall thereafter be entitled to purchase pursuant to this Warrant (in lieu of the kind and number of shares of Warrant Stock that the Holder would have been entitled to purchase or acquire immediately before such reorganization or reclassification) the kind and number of shares of stock of any class or classes or other securities or property for or into which such shares of Common Stock would have been exchanged, converted or reclassified if the Warrant Stock had been purchased immediately before such reorganization or reclassification at a total price not to exceed that payable upon the exercise of the unexercised portion of this Warrant. In case of any such reorganization or reclassification, appropriate provision (as determined by resolution of the Board of Directors of the Company) shall be made with respect to the rights and interests thereafter of the Holder of this Warrant, to the end that all the provisions of the Warrant (including adjustment provisions) shall thereafter be applicable, as nearly as reasonably practicable, in relation to such stock or other securities or property.

4.3 Statement of Adjustment of Warrant Stock. Whenever the number or kind of shares comprising Warrant Stock or the Exercise Price is adjusted pursuant to this Article 4, the Company shall promptly give notice to the Holder, stating that such an adjustment has been effected and setting forth the number and kind of shares purchasable and the amount of the then-current Exercise Price, and stating in reasonable detail the facts requiring such adjustment and the calculation of such adjustment.

4.6 No Other Adjustments. No adjustments in the number or kind or price of shares constituting Warrant Stock shall be made except as provided in this Article 4.

Article 5

Covenants of the Company

The Company covenants and agrees that:

5.1 Reservation of Shares. At all times, the Company will reserve and set apart and have, free from pre-emptive rights, a sufficient number of shares of authorized but unissued Common Stock or other securities, if applicable, to enable it at any time to fulfill all of its obligations hereunder.

5.2 Adjustment of Par Value. Before taking any action that would cause an adjustment reducing the Exercise Price per share below the then-current par value of the shares of Warrant Stock issuable upon exercise of the Warrant, the Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Warrant Stock at such adjusted price.

5.3 Notice of Significant Events. In case the Company proposes to:

6

(a) pay any dividend, payable in stock (of any class or classes) or in convertible securities, upon its Common Stock or to make any distribution (other than ordinary cash dividends) to the holders of its Common Stock;

(b) subdivide as a whole (by reclassification, by the issuance of a stock dividend on Common Stock, or otherwise) the number of shares of Common Stock then outstanding into a greater number of shares of Common Stock, with or without par value;

(c) effect any capital reorganization or reclassification of capital stock of the Company;

(d) consolidate with, or merge into, any other corporation or business or sell or convey its assets as an entirety or substantially as an entirety;

(e) effect the liquidation, dissolution, or winding up of the Company;

(f) make any other fundamental change in respect of which the Holder of this Warrant would have been entitled to vote, pursuant to the

corporation  law of the State of  Nevada,  if the  Warrant  had been  previously
exercised;

then the Company shall cause notice of any such  intended  action to be given to
the  Holder  (i) not less than  thirty  (30) days  before  the date on which the

transfer books of the Company shall close or a record be taken for such stock dividend or for determining rights to vote in respect of any fundamental change, including any capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or any other fundamental change, and (ii) not less than thirty (30) days before the effective date, in the case of any such capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or other fundamental change.

7

Article 6

Limitation of Liability

No provision of this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive dividends or to receive notice as a stockholder in respect of meetings of stockholders for the election of members of the Board of Directors of the Company or any other matter whatsoever as stockholders of the Company. In the absence of affirmative action by the Holder to purchase shares of Common Stock, no provision hereof shall give rise to any liability of the Holder for the purchase price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Article 7

Merger, Consolidation, or Change

7.1 Continuation of Warrant. Except as provided in Section 7.2, in the event that the Company proposes to consolidate with, or merge into, any other corporation or business or to transfer its property as an entirety or substantially as an entirety, or to effect the liquidation, dissolution, or winding up of the Company, or to change the Common Stock in any manner (other than to change its par value), then after the Company causes notice of such proposed action to be given to the Holder of record as provided in Section 5.3, the Holder shall be entitled, on or before the effective date of such merger, consolidation, transfer, liquidation, dissolution, winding up, or change to require the Company or the successor or purchasing entity, as the case may be, to (a) execute with the Holder an agreement providing that the Holder shall have the right thereafter and throughout the remaining term of the Warrant upon payment of the Exercise Price per share of Warrant Stock in effect immediately prior to such action to purchase with respect to each share of Warrant Stock issuable upon exercise of this Warrant the kind and amount of shares of stock and other securities, property (including cash) or any combination thereof which the Holder would have owned or have been entitled to receive after the happening of such consolidation, merger, sale, conveyance, or change had this Warrant been exercised with respect to such share of Warrant Stock immediately prior to such action and (b) make effective provision in its Articles of Incorporation or otherwise, if necessary, in order to effect such agreement. Such agreement shall provide for adjustments which shall be as nearly equivalent as practicable to the adjustments in Article 4 of this Warrant. The provisions of this Section 7.1 shall similarly apply to successive consolidations, mergers, sales, conveyances or changes.

7.2 Exception. Section 7.1 shall not apply to a consolidation or merger with a Person in which the Company is the surviving entity.

REGISTRATION RIGHTS

8.1 Piggyback Registration Rights. If, at any time on or before the expiration of this Warrant, the Company proposes to file a registration statement for the public sale of any of its Common Stock under the Securities Act, other than a registration statement originally declared effective prior to the date hereof or a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 under the Securities Act is applicable or pursuant to which Common Stock is registered other than for sale to the public, the Company shall, not later than thirty (30) days prior to the initial filing of the registration statement, deliver notice of its intent to file such registration statement to the Holder, setting forth the minimum and maximum proposed offering price, commissions, and discounts in connection with the offering, and other relevant information. Within ten (10) days after receipt of notice of the Company's intent to file a registration statement, the Holder shall be entitled to request that the Warrant Stock be included in such registration statement. In the event the Warrant Stock is included in the registration statement, the Holder may transfer the Warrant to an underwriter or broker for exercise by such underwriter or broker in connection with a distribution of the Warrant Stock.

8.2 Filing Obligations of the Company. In connection with any registration of the Warrant Stock effected under Section 8.1, the Company shall:

(a) prepare and file the registration statement and such amendments and supplements to the registration statement and the prospectus or offering circular used in connection therewith as may be necessary to keep the registration statement effective for a period of ninety (90) days and to comply with the provisions of the Securities Act and the rules and regulations thereunder with respect to the disposition of the Warrant Stock covered by the registration statement for the period required to effect the distribution thereof, but in no event shall the Company be required to do so for a period of more than ninety (90) days following the effective date of such registration statement;

(b) furnish to the Holder such number of copies of any prospectus or offering circular, including a preliminary prospectus, and of a full registration statement and exhibits in conformity with the requirements of the Securities Act and rules and regulations thereunder, as the Holder may reasonably request in order to facilitate the disposition of such securities;

(c) register or qualify the Warrant Stock covered by the registration statement, as the case may be, under the securities or blue sky laws of such jurisdictions as the Holder may reasonably request, and accomplish any and all other acts and things which may be necessary or advisable to permit sale in such jurisdictions of such Warrant Stock; provided, however, that the Company shall

9

not be required to register as a dealer or to qualify as a foreign corporation in any such jurisdictions or to escrow any shares of its capital stock.

8.3 Expenses. All expenses incurred by the Company in connection with any registration of the Warrant Stock effected under Section 8.1, including, without limitation, all registration and filing fees, fees and expenses of complying with state securities and blue sky laws, printing expenses, fees and expenses of the Company's counsel and accountants and fees and expenses of counsel for the Holder, shall be paid by the Company; provided, however, that all underwriting discounts and selling commission applicable to the Warrant Stock shall not be borne by the Company but shall be borne by the Holder.

8.4 Indemnification.

(a) By the Company. In connection with the filing of any registration statement and sales of Warrant Stock thereunder, the Company shall indemnify and hold harmless the Holder of this Warrant, any underwriter, and each other Person, if any, who controls the Holder or the underwriter within the meaning of the Securities Act, against losses, claims, damages or liabilities, joint or several (or actions in respect thereto) ("Losses"), to which any such Holder, underwriter, or controlling Person may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which the Warrant Stock was registered under the Securities Act, any preliminary prospectus, offering circular or final prospectus contained therein, or any amendment or supplement thereto, or any report filed with the Securities and Exchange Commission (the "Disclosure Documents"), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse any such Holder, underwriter, or controlling Person for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Company; provided, however, that the Company shall not be liable in any such case to the extent that any such Losses arise out of or omission or alleged omission made in such Disclosure Documents in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Holder of this Warrant for use specifically in connection with the preparation of such Disclosure Document.

(b) By the Holder. In connection with the filing of any registration statement and sales of the Warrant Stock thereunder, the Holder shall indemnify the Company, any underwriter, each of the Company's directors, each of its officers who signed such registration statement, and each other Person, if any, who controls the Company or the underwriter within the meaning of the Securities Act, against any Losses to which the Company, any of its directors, officers, or controlling Persons may become subject under the Securities Act or otherwise,

10

insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any of the Disclosure Documents or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, the underwriters, and any of their respective directors, officers, or controlling Persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Holder; provided, however, that such indemnification or reimbursement shall be payable in any such case only to the extent that such statement or alleged statement or omission or alleged omission is made in reliance on information furnished to the Company in writing by or on behalf of the Holder for use specifically in connection with the preparation of such Disclosure Document.

8.5 Discharge of Registration Obligations. In the event the Holder demands that the Warrant Stock be registered pursuant to Section 8.1 herein, the Company shall have the right to discharge the registration obligations set forth in Section 8.1 by repurchasing all or any part of the Warrant or Warrant Stock, as designated by the Holder, for cash at the Market Price determined as of the date the Holder demands registration or the date the Company delivers notice of its election to repurchase, whichever is higher. The Company must deliver written notice to the Holder of its election to repurchase the Warrant within thirty (30) days after receipt of a request by the Holder for registration. The Company shall deliver the purchase price to the Holder upon delivery of the Warrant or Warrant Stock. In the event the Company does not deliver cash to the Holder as required under this Section 8.5, the Company's right to repurchase under this Section 8.5 shall be terminated.

Transfer

3.1 Permitted Transfers. This Warrant shall be freely transferable, in whole or in part to any Affiliate of the Holder, subject to the limitations specified in Section 3.2. This Warrant shall not be transferable to any other Person except with the written consent of the Company, which consent shall not be unreasonably withheld, and subject to the limitations specified in Section 3.2.

3.2. Securities Laws. Neither this Warrant nor the Warrant Stock shall be transferable unless:

(a) either a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), is in effect covering this Warrant or the Warrant Stock, as the case may be, or the Company has received an opinion from the Company's counsel to the effect that such registration is not required, or the Holder has furnished to the Company an opinion of the Holder's counsel, which counsel shall be reasonably satisfactory to the Company, to the effect that such registration is not required; and

(b) the transfer complies with any applicable state securities laws.

In the event the Holder seeks an opinion as to transfer without registration from the Holder's counsel, the Company shall provide such factual information to the Holder's counsel as the Holder's counsel may reasonably request for the purpose of rendering such opinion and such counsel may rely on the accuracy and completeness of such information in rendering such opinion. Upon issuance at a time when the Common Stock is not publicly traded, the Warrant Stock will bear a legend describing the restrictions on transfer set forth in this Section 3.2.

3.3 Procedure. (a) The Holder of this Warrant, or of any warrant substituted therefor pursuant to the provisions of this Section 3.3, may, subject to the limitations set forth in Section 3.1, in person or by duly authorized attorney, surrender the same for exchange at the principal office of the Company and, within a reasonable time thereafter and without expense (other than transfer taxes, if any), receive in exchange therefor one or more duly executed warrants each evidencing the right to receive one share of Common Stock or such other number of shares as may be designated by the Holder at the time of surrender.

The Company and any agent of the Company may treat the Person in whose name a Warrant is registered as the owner of the Warrant for all purposes hereunder and neither the Company nor such agent shall be affected by notice to the contrary. The Company covenants and agrees to take and cause to be taken all

action necessary to effect such registrations, transfers and exchanges.

(i) the Warrant;

(ii) a written assignment of the Warrant, in substantially the form of the Assignment appearing at the end of this Warrant, naming the assignee and duly executed by the Holder; and

(iii) funds sufficient to pay any stock transfer taxes payable upon the making of such transfer.

The Company shall thereupon execute and deliver a new Warrant in the name of the assignee specified in such instrument of assignment. Upon issuance of the new Warrant or Warrants, the Warrant surrendered for transfer shall be canceled by the Company.

3.4 Expenses. The Company shall pay all expenses, taxes (other than transfer taxes), and other charges payable in connection with the preparation, issue and delivery of any new Warrant under this Article 3.

Article 4

Adjustments

4.1 Stock Splits, Stock Dividends and Reverse Stock Splits. If at any time the Company shall subdivide (by reclassification, by the issuance of a Common Stock dividend on Common Stock, or otherwise) its outstanding shares of Common Stock into a greater number, the number of shares of Common Stock that may be purchased hereunder shall be increased proportionately and the Exercise Price per share of Warrant Stock shall be decreased proportionately as of the effective date of such action. The effective date of a stock dividend shall be the date on which the dividend is declared. Issuance of a Common Stock dividend shall be treated as a subdivision of the whole number of shares of Common Stock outstanding immediately before the record date for such dividend into a number of shares equal to such whole number of shares so outstanding plus the number of shares issued as a stock dividend. If at any time the Company shall combine (by reclassification or otherwise) its outstanding number of shares of Common Stock into a lesser number, the number of shares of Warrant Stock that may be purchased hereunder shall be reduced proportionately and the Exercise Price per share of Warrant Stock shall be increased proportionately as of the effective date of such action.

4.2 Reorganization and Reclassification. In case of any capital reorganization or any reclassification of the capital stock of the Company while

5

this Warrant remains outstanding, the Holder of this Warrant shall thereafter be entitled to purchase pursuant to this Warrant (in lieu of the kind and number of shares of Warrant Stock that the Holder would have been entitled to purchase or acquire immediately before such reorganization or reclassification) the kind and number of shares of stock of any class or classes or other securities or property for or into which such shares of Common Stock would have been exchanged, converted or reclassified if the Warrant Stock had been purchased immediately before such reorganization or reclassification at a total price not to exceed that payable upon the exercise of the unexercised portion of this Warrant. In case of any such reorganization or reclassification, appropriate provision (as determined by resolution of the Board of Directors of the Company) shall be made with respect to the rights and interests thereafter of the Holder of this Warrant, to the end that all the provisions of the Warrant (including adjustment provisions) shall thereafter be applicable, as nearly as reasonably practicable, in relation to such stock or other securities or property.

4.3 Statement of Adjustment of Warrant Stock. Whenever the number or kind of shares comprising Warrant Stock or the Exercise Price is adjusted pursuant to this Article 4, the Company shall promptly give notice to the Holder, stating that such an adjustment has been effected and setting forth the number and kind of shares purchasable and the amount of the then-current Exercise Price, and stating in reasonable detail the facts requiring such adjustment and the calculation of such adjustment.

4.6 No Other Adjustments. No adjustments in the number or kind or price of shares constituting Warrant Stock shall be made except as provided in this Article 4.

Article 5

Covenants of the Company

The Company covenants and agrees that:

5.1 Reservation of Shares. At all times, the Company will reserve and set apart and have, free from pre-emptive rights, a sufficient number of shares of authorized but unissued Common Stock or other securities, if applicable, to enable it at any time to fulfill all of its obligations hereunder.

5.2 Adjustment of Par Value. Before taking any action that would cause an adjustment reducing the Exercise Price per share below the then-current par value of the shares of Warrant Stock issuable upon exercise of the Warrant, the Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Warrant Stock at such adjusted price.

5.3 Notice of Significant Events. In case the Company proposes to:

6

(a) pay any dividend, payable in stock (of any class or classes) or in convertible securities, upon its Common Stock or to make any distribution (other than ordinary cash dividends) to the holders of its Common Stock;

(b) subdivide as a whole (by reclassification, by the issuance of a stock dividend on Common Stock, or otherwise) the number of shares of Common Stock then outstanding into a greater number of shares of Common Stock, with or without par value;

(c) effect any capital reorganization or reclassification of capital stock of the Company;

(d) consolidate with, or merge into, any other corporation or business or sell or convey its assets as an entirety or substantially as an entirety;

(e) effect the liquidation, dissolution, or winding up of the Company;

(f) make any other fundamental change in respect of which the Holder of this Warrant would have been entitled to vote, pursuant to the

corporation  law of the State of  Nevada,  if the  Warrant  had been  previously
exercised;

then the Company shall cause notice of any such  intended  action to be given to
the  Holder  (i) not less than  thirty  (30) days  before  the date on which the

transfer books of the Company shall close or a record be taken for such stock dividend or for determining rights to vote in respect of any fundamental change, including any capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or any other fundamental change, and (ii) not less than thirty (30) days before the effective date, in the case of any such capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or other fundamental change.

Article 6

Limitation of Liability

No provision of this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive dividends or to receive notice as a stockholder in respect of meetings of stockholders for the election of members of the Board of Directors of the Company or any other matter whatsoever as stockholders of the Company. In the absence of affirmative action by the Holder to purchase shares of Common Stock, no provision hereof shall give rise to any liability of the Holder for the purchase price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Article 7

Merger, Consolidation, or Change

7.1 Continuation of Warrant. Except as provided in Section 7.2, in the event that the Company proposes to consolidate with, or merge into, any other corporation or business or to transfer its property as an entirety or substantially as an entirety, or to effect the liquidation, dissolution, or winding up of the Company, or to change the Common Stock in any manner (other than to change its par value), then after the Company causes notice of such proposed action to be given to the Holder of record as provided in Section 5.3, the Holder shall be entitled, on or before the effective date of such merger, consolidation, transfer, liquidation, dissolution, winding up, or change to require the Company or the successor or purchasing entity, as the case may be, to (a) execute with the Holder an agreement providing that the Holder shall have the right thereafter and throughout the remaining term of the Warrant upon payment of the Exercise Price per share of Warrant Stock in effect immediately prior to such action to purchase with respect to each share of Warrant Stock issuable upon exercise of this Warrant the kind and amount of shares of stock and other securities, property (including cash) or any combination thereof which the Holder would have owned or have been entitled to receive after the happening of such consolidation, merger, sale, conveyance, or change had this Warrant been exercised with respect to such share of Warrant Stock immediately prior to such action and (b) make effective provision in its Articles of Incorporation or otherwise, if necessary, in order to effect such agreement. Such agreement shall provide for adjustments which shall be as nearly equivalent as practicable to the adjustments in Article 4 of this Warrant. The provisions of this Section 7.1 shall similarly apply to successive consolidations, mergers, sales, conveyances or changes.

7.2 Exception. Section 7.1 shall not apply to a consolidation or merger with a Person in which the Company is the surviving entity.

REGISTRATION RIGHTS

8.1 Piggyback Registration Rights. If, at any time on or before the expiration of this Warrant, the Company proposes to file a registration statement for the public sale of any of its Common Stock under the Securities Act, other than a registration statement originally declared effective prior to the date hereof or a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 under the Securities Act is applicable or pursuant to which Common Stock is registered other than for sale to the public, the Company shall, not later than thirty (30) days prior to the initial filing of the registration statement, deliver notice of its intent to file such registration statement to the Holder, setting forth the minimum and maximum proposed offering price, commissions, and discounts in connection with the offering, and other relevant information. Within ten (10) days after receipt of notice of the Company's intent to file a registration statement, the Holder shall be entitled to request that the Warrant Stock be included in such registration statement. In the event the Warrant Stock is included in the registration statement, the Holder may transfer the Warrant to an underwriter or broker for exercise by such underwriter or broker in connection with a distribution of the Warrant Stock.

8.2 Filing Obligations of the Company. In connection with any registration of the Warrant Stock effected under Section 8.1, the Company shall:

(a) prepare and file the registration statement and such amendments and supplements to the registration statement and the prospectus or offering circular used in connection therewith as may be necessary to keep the registration statement effective for a period of ninety (90) days and to comply with the provisions of the Securities Act and the rules and regulations thereunder with respect to the disposition of the Warrant Stock covered by the registration statement for the period required to effect the distribution thereof, but in no event shall the Company be required to do so for a period of more than ninety (90) days following the effective date of such registration statement;

(b) furnish to the Holder such number of copies of any prospectus or offering circular, including a preliminary prospectus, and of a full registration statement and exhibits in conformity with the requirements of the Securities Act and rules and regulations thereunder, as the Holder may reasonably request in order to facilitate the disposition of such securities;

(c) register or qualify the Warrant Stock covered by the registration statement, as the case may be, under the securities or blue sky laws of such jurisdictions as the Holder may reasonably request, and accomplish any and all other acts and things which may be necessary or advisable to permit sale in such jurisdictions of such Warrant Stock; provided, however, that the Company shall

9

not be required to register as a dealer or to qualify as a foreign corporation in any such jurisdictions or to escrow any shares of its capital stock.

8.3 Expenses. All expenses incurred by the Company in connection with any registration of the Warrant Stock effected under Section 8.1, including, without limitation, all registration and filing fees, fees and expenses of complying with state securities and blue sky laws, printing expenses, fees and expenses of the Company's counsel and accountants and fees and expenses of counsel for the Holder, shall be paid by the Company; provided, however, that all underwriting discounts and selling commission applicable to the Warrant Stock shall not be borne by the Company but shall be borne by the Holder.

8.4 Indemnification.

(a) By the Company. In connection with the filing of any registration statement and sales of Warrant Stock thereunder, the Company shall indemnify and hold harmless the Holder of this Warrant, any underwriter, and each other Person, if any, who controls the Holder or the underwriter within the meaning of the Securities Act, against losses, claims, damages or liabilities, joint or several (or actions in respect thereto) ("Losses"), to which any such Holder, underwriter, or controlling Person may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which the Warrant Stock was registered under the Securities Act, any preliminary prospectus, offering circular or final prospectus contained therein, or any amendment or supplement thereto, or any report filed with the Securities and Exchange Commission (the "Disclosure Documents"), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse any such Holder, underwriter, or controlling Person for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Company; provided, however, that the Company shall not be liable in any such case to the extent that any such Losses arise out of or omission or alleged omission made in such Disclosure Documents in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Holder of this Warrant for use specifically in connection with the preparation of such Disclosure Document.

(b) By the Holder. In connection with the filing of any registration statement and sales of the Warrant Stock thereunder, the Holder shall indemnify the Company, any underwriter, each of the Company's directors, each of its officers who signed such registration statement, and each other Person, if any, who controls the Company or the underwriter within the meaning of the Securities Act, against any Losses to which the Company, any of its directors, officers, or

10

controlling Persons may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any of the Disclosure Documents or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, the underwriters, and any of their respective directors, officers, or controlling Persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Holder; provided, however, that such indemnification or reimbursement shall be payable in any such case only to the extent that such statement or alleged statement or omission or alleged omission is made in reliance on information furnished to the Company in writing by or on behalf of the Holder for use specifically in connection with the preparation of such Disclosure Document.

8.5 Discharge of Registration Obligations. In the event the Holder demands that the Warrant Stock be registered pursuant to Section 8.1 herein, the Company shall have the right to discharge the registration obligations set forth in Section 8.1 by repurchasing all or any part of the Warrant or Warrant Stock, as designated by the Holder, for cash at the Market Price determined as of the date the Holder demands registration or the date the Company delivers notice of its election to repurchase, whichever is higher. The Company must deliver written notice to the Holder of its election to repurchase the Warrant within thirty (30) days after receipt of a request by the Holder for registration. The Company shall deliver the purchase price to the Holder upon delivery of the Warrant or Warrant Stock. In the event the Company does not deliver cash to the Holder as required under this Section 8.5, the Company's right to repurchase under this Section 8.5 shall be terminated.

Article 3

Transfer

3.1 Permitted Transfers. This Warrant shall be freely transferable, in whole or in part to any Affiliate of the Holder, subject to the limitations specified in Section 3.2. This Warrant shall not be transferable to any other Person except with the written consent of the Company, which consent shall not be unreasonably withheld, and subject to the limitations specified in Section 3.2.

3.2. Securities Laws. Neither this Warrant nor the Warrant Stock shall be transferable unless:

(a) either a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), is in effect covering this Warrant or the Warrant Stock, as the case may be, or the Company has received an opinion from the Company's counsel to the effect that such registration is not required, or the Holder has furnished to the Company an opinion of the Holder's counsel, which counsel shall be reasonably satisfactory to the Company, to the effect that such registration is not required; and

(b) the transfer complies with any applicable state securities laws.

In the event the Holder seeks an opinion as to transfer without registration from the Holder's counsel, the Company shall provide such factual information to the Holder's counsel as the Holder's counsel may reasonably request for the purpose of rendering such opinion and such counsel may rely on the accuracy and completeness of such information in rendering such opinion. Upon issuance at a time when the Common Stock is not publicly traded, the Warrant Stock will bear a legend describing the restrictions on transfer set forth in this Section 3.2.

3.3 Procedure. (a) The Holder of this Warrant, or of any warrant substituted therefor pursuant to the provisions of this Section 3.3, may, subject to the limitations set forth in Section 3.1, in person or by duly authorized attorney, surrender the same for exchange at the principal office of the Company and, within a reasonable time thereafter and without expense (other than transfer taxes, if any), receive in exchange therefor one or more duly executed warrants each evidencing the right to receive one share of Common Stock or such other number of shares as may be designated by the Holder at the time of surrender.

The Company and any agent of the Company may treat the Person in whose name a Warrant is registered as the owner of the Warrant for all purposes hereunder and neither the Company nor such agent shall be affected by notice to

4

the contrary. The Company covenants and agrees to take and cause to be taken all action necessary to effect such registrations, transfers and exchanges.

(b) The Holder may transfer the Warrant on the books of the Company by surrendering to the Company:

(i) the Warrant;

(ii) a written assignment of the Warrant, in substantially the form of the Assignment appearing at the end of this Warrant, naming the assignee and duly executed by the Holder; and

(iii) funds sufficient to pay any stock transfer taxes payable upon the making of such transfer.

The Company shall thereupon execute and deliver a new Warrant in the name of the assignee specified in such instrument of assignment. Upon issuance of the new Warrant or Warrants, the Warrant surrendered for transfer shall be canceled by the Company.

3.4 Expenses. The Company shall pay all expenses, taxes (other than transfer taxes), and other charges payable in connection with the preparation, issue and delivery of any new Warrant under this Article 3.

Article 4

Adjustments

4.1 Stock Splits, Stock Dividends and Reverse Stock Splits. If at any time the Company shall subdivide (by reclassification, by the issuance of a Common Stock dividend on Common Stock, or otherwise) its outstanding shares of Common Stock into a greater number, the number of shares of Common Stock that may be purchased hereunder shall be increased proportionately and the Exercise Price per share of Warrant Stock shall be decreased proportionately as of the effective date of such action. The effective date of a stock dividend shall be the date on which the dividend is declared. Issuance of a Common Stock dividend shall be treated as a subdivision of the whole number of shares of Common Stock outstanding immediately before the record date for such dividend into a number of shares equal to such whole number of shares so outstanding plus the number of shares issued as a stock dividend. If at any time the Company shall combine (by reclassification or otherwise) its outstanding number of shares of Common Stock into a lesser number, the number of shares of Warrant Stock that may be purchased hereunder shall be reduced proportionately and the Exercise Price per share of Warrant Stock shall be increased proportionately as of the effective date of such action.

4.2 Reorganization and Reclassification. In case of any capital reorganization or any reclassification of the capital stock of the Company while

5

this Warrant remains outstanding, the Holder of this Warrant shall thereafter be entitled to purchase pursuant to this Warrant (in lieu of the kind and number of shares of Warrant Stock that the Holder would have been entitled to purchase or acquire immediately before such reorganization or reclassification) the kind and number of shares of stock of any class or classes or other securities or property for or into which such shares of Common Stock would have been exchanged, converted or reclassified if the Warrant Stock had been purchased immediately before such reorganization or reclassification at a total price not to exceed that payable upon the exercise of the unexercised portion of this Warrant. In case of any such reorganization or reclassification, appropriate provision (as determined by resolution of the Board of Directors of the Company) shall be made with respect to the rights and interests thereafter of the Holder of this Warrant, to the end that all the provisions of the Warrant (including adjustment provisions) shall thereafter be applicable, as nearly as reasonably practicable, in relation to such stock or other securities or property.

4.3 Statement of Adjustment of Warrant Stock. Whenever the number or kind of shares comprising Warrant Stock or the Exercise Price is adjusted pursuant to this Article 4, the Company shall promptly give notice to the Holder, stating that such an adjustment has been effected and setting forth the number and kind of shares purchasable and the amount of the then-current Exercise Price, and stating in reasonable detail the facts requiring such adjustment and the calculation of such adjustment.

4.6 No Other Adjustments. No adjustments in the number or kind or price of shares constituting Warrant Stock shall be made except as provided in this Article 4.

Article 5

Covenants of the Company

The Company covenants and agrees that:

5.1 Reservation of Shares. At all times, the Company will reserve and set apart and have, free from pre-emptive rights, a sufficient number of shares of authorized but unissued Common Stock or other securities, if applicable, to enable it at any time to fulfill all of its obligations hereunder.

5.2 Adjustment of Par Value. Before taking any action that would cause an adjustment reducing the Exercise Price per share below the then-current par value of the shares of Warrant Stock issuable upon exercise of the Warrant, the Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Warrant Stock at such adjusted price.

5.3 Notice of Significant Events. In case the Company proposes to:

6

(a) pay any dividend, payable in stock (of any class or classes) or in convertible securities, upon its Common Stock or to make any distribution (other than ordinary cash dividends) to the holders of its Common Stock;

(b) subdivide as a whole (by reclassification, by the issuance of a stock dividend on Common Stock, or otherwise) the number of shares of Common Stock then outstanding into a greater number of shares of Common Stock, with or without par value;

(c) effect any capital reorganization or reclassification of capital stock of the Company;

(d) consolidate with, or merge into, any other corporation or business or sell or convey its assets as an entirety or substantially as an entirety;

(e) effect the liquidation, dissolution, or winding up of the Company;

(f) make any other fundamental change in respect of which the Holder of this Warrant would have been entitled to vote, pursuant to the

corporation  law of the State of  Nevada,  if the  Warrant  had been  previously
exercised;

then the Company shall cause notice of any such  intended  action to be given to
the  Holder  (i) not less than  thirty  (30) days  before  the date on which the

transfer books of the Company shall close or a record be taken for such stock dividend or for determining rights to vote in respect of any fundamental change, including any capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or any other fundamental change, and (ii) not less than thirty (30) days before the effective date, in the case of any such capital reorganization, reclassification, consolidation, merger, transfer, liquidation, dissolution, winding up, or other fundamental change.

7

Article 6

Limitation of Liability

No provision of this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive dividends or to receive notice as a stockholder in respect of meetings of stockholders for the election of members of the Board of Directors of the Company or any other matter whatsoever as stockholders of the Company. In the absence of affirmative action by the Holder to purchase shares of Common Stock, no provision hereof shall give rise to any liability of the Holder for the purchase price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Article 7

Merger, Consolidation, or Change

7.1 Continuation of Warrant. Except as provided in Section 7.2, in the event that the Company proposes to consolidate with, or merge into, any other corporation or business or to transfer its property as an entirety or substantially as an entirety, or to effect the liquidation, dissolution, or winding up of the Company, or to change the Common Stock in any manner (other than to change its par value), then after the Company causes notice of such proposed action to be given to the Holder of record as provided in Section 5.3, the Holder shall be entitled, on or before the effective date of such merger, consolidation, transfer, liquidation, dissolution, winding up, or change to require the Company or the successor or purchasing entity, as the case may be, to (a) execute with the Holder an agreement providing that the Holder shall have the right thereafter and throughout the remaining term of the Warrant upon payment of the Exercise Price per share of Warrant Stock in effect immediately prior to such action to purchase with respect to each share of Warrant Stock issuable upon exercise of this Warrant the kind and amount of shares of stock and other securities, property (including cash) or any combination thereof which the Holder would have owned or have been entitled to receive after the happening of such consolidation, merger, sale, conveyance, or change had this Warrant been exercised with respect to such share of Warrant Stock immediately prior to such action and (b) make effective provision in its Articles of Incorporation or otherwise, if necessary, in order to effect such agreement. Such agreement shall provide for adjustments which shall be as nearly equivalent as practicable to the adjustments in Article 4 of this Warrant. The provisions of this Section 7.1 shall similarly apply to successive consolidations, mergers, sales, conveyances or changes.

7.2 Exception. Section 7.1 shall not apply to a consolidation or merger with a Person in which the Company is the surviving entity.

Article 8

REGISTRATION RIGHTS

8.1 Piggyback Registration Rights. If, at any time on or before the expiration of this Warrant, the Company proposes to file a registration statement for the public sale of any of its Common Stock under the Securities Act, other than a registration statement originally declared effective prior to the date hereof or a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 under the Securities Act is applicable or pursuant to which Common Stock is registered other than for sale to the public, the Company shall, not later than thirty (30) days prior to the initial filing of the registration statement, deliver notice of its intent to file such registration statement to the Holder, setting forth the minimum and maximum proposed offering price, commissions, and discounts in connection with the offering, and other relevant information. Within ten (10) days after receipt of notice of the Company's intent to file a registration statement, the Holder shall be entitled to request that the Warrant Stock be included in such registration statement. In the event the Warrant Stock is included in the registration statement, the Holder may transfer the Warrant to an underwriter or broker for exercise by such underwriter or broker in connection with a distribution of the Warrant Stock.

8.2 Filing Obligations of the Company. In connection with any registration of the Warrant Stock effected under Section 8.1, the Company shall:

(a) prepare and file the registration statement and such amendments and supplements to the registration statement and the prospectus or offering circular used in connection therewith as may be necessary to keep the registration statement effective for a period of ninety (90) days and to comply with the provisions of the Securities Act and the rules and regulations thereunder with respect to the disposition of the Warrant Stock covered by the registration statement for the period required to effect the distribution thereof, but in no event shall the Company be required to do so for a period of more than ninety (90) days following the effective date of such registration statement;

(b) furnish to the Holder such number of copies of any prospectus or offering circular, including a preliminary prospectus, and of a full registration statement and exhibits in conformity with the requirements of the Securities Act and rules and regulations thereunder, as the Holder may reasonably request in order to facilitate the disposition of such securities;

(c) register or qualify the Warrant Stock covered by the registration statement, as the case may be, under the securities or blue sky laws of such jurisdictions as the Holder may reasonably request, and accomplish any and all other acts and things which may be necessary or advisable to permit sale in such jurisdictions of such Warrant Stock; provided, however, that the Company shall

9

not be required to register as a dealer or to qualify as a foreign corporation in any such jurisdictions or to escrow any shares of its capital stock.

8.3 Expenses. All expenses incurred by the Company in connection with any registration of the Warrant Stock effected under Section 8.1, including, without limitation, all registration and filing fees, fees and expenses of complying with state securities and blue sky laws, printing expenses, fees and expenses of the Company's counsel and accountants and fees and expenses of counsel for the Holder, shall be paid by the Company; provided, however, that all underwriting discounts and selling commission applicable to the Warrant Stock shall not be borne by the Company but shall be borne by the Holder.

8.4 Indemnification.

(a) By the Company. In connection with the filing of any registration statement and sales of Warrant Stock thereunder, the Company shall indemnify and hold harmless the Holder of this Warrant, any underwriter, and each other Person, if any, who controls the Holder or the underwriter within the meaning of the Securities Act, against losses, claims, damages or liabilities, joint or several (or actions in respect thereto) ("Losses"), to which any such Holder, underwriter, or controlling Person may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which the Warrant Stock was registered under the Securities Act, any preliminary prospectus, offering circular or final prospectus contained therein, or any amendment or supplement thereto, or any report filed with the Securities and Exchange Commission (the "Disclosure Documents"), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse any such Holder, underwriter, or controlling Person for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Company; provided, however, that the Company shall not be liable in any such case to the extent that any such Losses arise out of or omission or alleged omission made in such Disclosure Documents in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Holder of this Warrant for use specifically in connection with the preparation of such Disclosure Document.

(b) By the Holder. In connection with the filing of any registration statement and sales of the Warrant Stock thereunder, the Holder shall indemnify the Company, any underwriter, each of the Company's directors, each of its officers who signed such registration statement, and each other Person, if any, who controls the Company or the underwriter within the meaning of the Securities Act, against any Losses to which the Company, any of its directors, officers, or

10

controlling Persons may become subject under the Securities Act or otherwise, insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any of the Disclosure Documents or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, the underwriters, and any of their respective directors, officers, or controlling Persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claims, excluding any amounts paid in settlement of litigation, commenced or threatened, if such settlement is effected without the prior written consent of the Holder; provided, however, that such indemnification or reimbursement shall be payable in any such case only to the extent that such statement or alleged statement or omission or alleged omission is made in reliance on information furnished to the Company in writing by or on behalf of the Holder for use specifically in connection with the preparation of such Disclosure Document.

8.5 Discharge of Registration Obligations. In the event the Holder demands that the Warrant Stock be registered pursuant to Section 8.1 herein, the Company shall have the right to discharge the registration obligations set forth in Section 8.1 by repurchasing all or any part of the Warrant or Warrant Stock, as designated by the Holder, for cash at the Market Price determined as of the date the Holder demands registration or the date the Company delivers notice of its election to repurchase, whichever is higher. The Company must deliver written notice to the Holder of its election to repurchase the Warrant within thirty (30) days after receipt of a request by the Holder for registration. The Company shall deliver the purchase price to the Holder upon delivery of the Warrant or Warrant Stock. In the event the Company does not deliver cash to the Holder as required under this Section 8.5, the Company's right to repurchase under this Section 8.5 shall be terminated.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of Abraxas Petroleum Corporation

We have audited the accompanying consolidated balance sheet of Abraxas Petroleum Corporation and Subsidiaries (the "Company") as of December 31, 2000, and the related consolidated statements of operations, stockholders' equity (deficit), and cash flows for the year then ended. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. 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 audit provides a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2000, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

ABRAXAS PETROLEUM CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 1998, 1999, and 2000

1. Organization and Significant Accounting Policies

Nature of Operations

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

The consolidated financial statements include the accounts of the Company, its wholly-owned foreign subsidiary Canadian Abraxas Petroleum Limited ("Canadian Abraxas") and the Company's 49% owned subsidiary Grey Wolf Exploration Inc. ("Grey Wolf") - see Note 9. Minority interest represents the minority shareholders' proportionate share of the equity and income of Grey Wolf. See Note 18 regarding potential acquisition of remaining Grey Wolf shares.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management believes that it is reasonably possible that estimates of proved crude oil and natural gas revenues could significantly change in the future.

Concentration of Credit Risk

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

Equipment Inventory

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

Oil and Gas Properties

The Company follows the full cost method of accounting for crude oil and natural gas properties. Under this method, all direct costs and certain indirect costs associated with acquisition of properties and successful as well as unsuccessful exploration and development activities are capitalized. Depreciation, depletion, and amortization ("DD&A") of capitalized crude oil and natural gas properties and estimated future development costs, excluding unproved properties, are based on the unit-of-production method based on proved reserves. Net capitalized costs of crude oil and natural gas properties, less related deferred taxes, are limited, by country, to the lower of unamortized cost or the cost ceiling, defined as the sum of the present value of estimated future net revenues from proved reserves based on unescalated prices discounted at 10 percent, plus the cost of properties not being amortized, if any, plus the lower of cost or estimated fair value of unproved properties included in the costs being amortized, if any, less related income taxes. Excess costs are charged to proved property impairment expense. No gain or loss is recognized upon sale or disposition of crude oil and natural gas properties, except in unusual circumstances - see Note 3.

F-11

Unproved properties represent costs associated with properties on which the Company is performing exploration activities or intends to commence such activities. These costs are reviewed periodically for possible impairments or reduction in value based on geological and geophysical data. If a reduction in value has occurred, costs being amortized are increased. The Company believes that the unproved properties will be substantially evaluated in six to thirty-six months and it will begin to amortize these costs at such time. During 1998, 1999 and 2000, the Company capitalized $414,000, $193,000 and $589,000 of interest expense, respectively, based on the cost of major development projects in progress.

Other Property and Equipment

Other property and equipment are recorded on the basis of cost. Depreciation of gas gathering and processing facilities and other property and equipment is provided over the estimated useful lives using the straight-line method. Major renewals and betterments are recorded as additions to the property and equipment accounts. Repairs that do not improve or extend the useful lives of assets are expensed.

Hedging

The Company periodically enters into agreements to hedge the risk of future crude oil and natural gas price fluctuations. Such agreements primarily in the form of price swaps, may either fix or support crude oil and natural gas prices or limit the impact of price fluctuations with respect to the Company's sale of crude oil and natural gas. Gains and losses on such hedging activities are recognized in oil and gas production revenues when hedged production is sold. The net cash flows related to any recognized gains or losses associated with these hedges are reported as cash flows from operations. If the hedge is terminated prior to expected maturity, gains or losses are deferred and included in income in the same period as the physical production required by the contract is delivered.

Stock-Based Compensation

The Company accounts for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees," and related interpretations. Accordingly, compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company's stock at the date of the grant over the amount an employee must pay to acquire the stock.

Effective July 1, 2000, the Financial Accounting Standards Board ("FASB") issued FIN 44, "Accounting for Certain Transactions Involving Stock Compensation", an interpretation of APB No. 25. Under the interpretation, certain modifications to fixed stock option awards which were made subsequent to December 15, 1998, and were not exercised prior to July 1, 2000, require that the awards be accounted for as variable until they are exercised, forfeited, or expired. In March 1999, the Company amended the exercise price to $2.06 on all options with an existing exercise price greater than $2.06. See Note 7. The Company recognized approximately $2.8 million as General and Administrative (Stock-based compensation) expense during 2000.

Foreign Currency Translation

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

Fair Value of Financial Instruments

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

F-12

Restoration, Removal and Environmental Liabilities

The estimated costs of restoration and removal of major processing facilities are accrued on a straight-line basis over the life of the property. The estimated future costs for known environmental remediation requirements are accrued when it is probable that a liability has been incurred and the amount of remediation costs can be reasonably estimated. These amounts are the undiscounted, future estimated costs under existing regulatory requirements and using existing technology.

Revenue Recognition

The Company recognizes crude oil and natural gas revenue from its interest in producing wells as crude oil and natural gas is sold from those wells net of royalties. Revenue from the processing of natural gas is recognized in the period the service is performed. The Company utilizes the sales method to account for gas production volume imbalances. Under this method, income is recorded based on the Company's net revenue interest in production taken for delivery. Management does not believe that the Company had material gas imbalances at December 31, 1999 or 2000.

The Company adopted the provisions of Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements" issued by the Staff of the Securities and Exchange Commission. The impact of adopting SAB No. 101 was not material to the Company.

Deferred Financing Fees

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

Federal Income Taxes

The Company records income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

New Accounting Pronouncement

Statement of Financial Accounting Standards, ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities", is effective for the Company on January 1, 2001. SFAS 133, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. All derivatives, whether designated in hedging relationships or not, will be required to be recorded on the balance sheet at fair value. If the derivative is designated a fair-value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated a cash-flow hedge, changes in the fair value of the derivative will be recorded in other comprehensive income (OCI) and will be recognized in the income statement when the hedged item affects earnings. SFAS 133 defines new requirements for designation and documentation of hedging relationships as well as ongoing effectiveness assessments in order to use hedge accounting. For a derivative that does not qualify as a hedge, changes in fair value will we recognized in earnings.

The Company expects that at January 1, 2001, it will record a liability of $38 million with the offstting charge to OCI as a cumulative transition adjustment for derivatives designated as cash-flow hedges prior to adopting SFAS 133.

Reclassifications

Certain prior years balances have been reclassified for comparative purposes.

2. Liquidity

The Company will have three principal sources of liquidity going forward: (i) cash on hand, (ii) cash flow from operations, and (iii) the production payment with Mirant. The Company also intends to continue to sell certain non-core properties, although the terms of the First Lien Notes indenture, the Second Lien Notes indenture and the Old Notes indenture substantially limit our use of proceeds from such sales. The Company expects

F-13

that the significantly improved commodity prices realized by it compared to those received in 1998 and the expiration of a significant portion of the crude oil and natural gas hedges that it had put in place in earlier years will improve its liquidity position in 2001. Should commodity prices fall, all of the Company's capital expenditures are discretionary and can be delayed to maintain liquidity. While the availability of capital resources cannot be predicted with certainty and is dependent upon a number of factors including factors outside of management's control, management believes that the net cash flow from operations plus cash on hand, cash available under the production payment and the proceeds from the sale of additional non-core properties will be adequate to fund operations and planned capital expenditures.

The Company's operating results had been adversely affected by low crude oil and natural gas prices in 1998 and early 1999. In addition, the Company had significant interest payments due on its long term debt. As a result of these conditions, the Company issued $63.5 million of debt securities ("First Lien Notes") in March 1999. The First Lien Notes are unconditionally guaranteed on a senior basis, jointly and severally, by Canadian Abraxas, Sandia Oil and Gas Corporation ("Sandia") and Wamsutter Holdings, Inc. ("Wamsutter"), 100%-owned subsidiaries of Abraxas. These First Lien Notes and the guarantees are secured by a first lien or charge on substantially all of the crude oil and natural gas properties and natural gas processing plants owned by Abraxas, Canadian Abraxas, Sandia and Wamsutter and the shares of Grey Wolf owned by the Company and Canadian Abraxas and bear interest at 12.875%, payable semi-annually on March 15 and September 15. The First Lien Notes will mature in 2003. Proceeds from the First Lien Notes were used to re-pay the Company's Credit Facility, and re-pay approximately $10 million of debt assumed in connection with the Company's acquisition of New Cache in January 1999 with the remainder being used for general corporate purposes.

In October 1999 the Company entered into a non-recourse Dollar Denominated Production Payment agreement (the "Production Payment") with a third party. The Production Payment has an aggregate total availability of up to $50 million at 15% interest. The Production Payment relates to a portion of the production from several natural gas wells in the Edwards Trend, in south Texas. As of December 31, 2000, the Company had received $10.4 million under this agreement. The outstanding balance as of December 31, 2000 is $5.2 million. See Note 5.

In December 1999, Abraxas and Canadian Abraxas completed an Exchange Offer ("Exchange Offer") whereby they exchanged $270 million of 11.5% Senior Notes due 2004 (the "Old Notes") for $189 million in new 11.5% Senior Secured Notes due 2004 (the "Second Lien Notes"), 16,078,990 shares of Abraxas common stock and contingent value rights. An additional $5 million of the Second Lien Notes were issued for payment of fees and expenses. See Note 5 and 6.

The Second Lien Notes are senior obligations of Abraxas and Canadian Abraxas and are jointly and severally guaranteed by Sandia and Wamsutter. The Second Lien Notes and the guarantees are secured by a second lien or charge on substantially all of the crude oil and natural gas properties and natural gas processing plants owned by Abraxas, Canadian Abraxas, Sandia and Wamsutter, as well as shares of common stock of Grey Wolf owned by Abraxas and Canadian Abraxas. The Exchange Offer reduced the Company's long term debt by $75.9 million and annual interest payments by approximately $8.8 million.

In March 2000, the Company sold its interests in certain crude oil and natural gas properties in Wyoming. Simultaneously, a limited partnership, in which the Company has a limited partnership interest and Wamsutter acts as general partner, sold its crude oil and natural gas properties in the same area. The Company realized $34 million in net proceeds from the sales, which enabled the Company to meet its interest obligations throughout 2000. See Note 3.

In March 2001, we announced that we had engaged Credit Lyonnais Securities (USA) Inc. and CIBC World Markets Corp. to assist us in a review of alternative financial strategies. Under the terms of this engagement, we may restructure, refinance or recapitalize some or all of our existing debt and/or issue equity securities.

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

3. Acquisitions and Divestitures

Wyoming Properties Divestiture

In November 1998, the Company sold its interest in certain Wyoming properties to Abraxas Wamsutter L.P., a Texas limited partnership (the "Partnership"), for approximately $58.6 million and a minority equity ownership in the Partnership. Wamsutter initially owned a one percent interest and acted

F-14

as general partner of the Partnership. The investment in the Partnership was accounted for by the equity method. After certain payback requirements are satisfied, the Company's interest would increase to 35% initially and could increase to as high as 65%. The Company also received a management fee and reimbursement of certain overhead costs from the Partnership which amounted to $50,700; $594,700 and $112,700 for the years ended December 31, 1998, 1999 and 2000 respectively. See Abraxas Wamsutter L.P. Divestiture, below.

New Cache Petroleums LTD Acquisition

In January 1999, Canadian Abraxas completed the acquisition of New Cache Petroleums, LTD, ("New Cache"), for approximately $78 million in cash and the assumption of approximately $10 million in debt. The debt was paid off with a portion of the proceeds from the sale of the First Lien Notes.

The acquisition was accounted for as a purchase, and the purchase price was allocated to the crude oil and natural gas properties based on the fair values of the properties acquired. Results of operations for New Cache have been included in the consolidated financial statements since January 1999.

Abraxas Wamsutter L.P. Divestiture

In March 2000, the Partnership sold all of its interest in its crude oil and natural gas properties to a third party. Prior to the sale of these properties, effective January 1, 2000, the Company's equity investee share of oil and gas property cost, results of operations and amortization were not material to consolidated operations or financial position. As a result of the sale, the Company received approximately $34 million, which represented a proportional interest in the Partnership's proved properties

The condensed pro forma financial information presented below summarizes on an unaudited pro forma basis, approximate results of the Company's consolidated results of operations for the year ended December 31, 1999, assuming the divestiture had occurred on January 1, 1999.

Long-Term Indebtedness

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

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

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

The Old Notes are joint and several obligations of the Company and rank pari passu in right of payment to all existing and future unsubordinated indebtedness of the Company. The Old Notes rank senior in right of payment to all future subordinated indebtedness of the Company. The Old Notes are, however, effectively subordinated to the First Lien Notes to the extent of the value of the collateral securing the First Lien Notes and the Second Lien Notes to the extent of the value of the collateral securing the Second Lien Notes. The Old Notes are unconditionally guaranteed, on a senior basis by Sandia. The guarantee is a general unsecured obligation of Sandia and ranks pari passu in right of payment to all unsubordinated indebtedness of Sandia and senior in right of payment to all subordinated indebtedness of Sandia. The guarantee is effectively subordinated to the First Lien Notes and the Second Lien Notes to the extent of the value of the collateral

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

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

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

F-16

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

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

The First Lien Notes indenture contains certain covenants that limit the ability of Abraxas and certain of its subsidiaries, including the guarantors of the First Lien Notes (the "Restricted Subsidiaries") to, among other things, incur additional indebtedness, pay dividends or make certain other restricted payments, consummate certain asset sales, enter into certain transactions with affiliates, incur liens, merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the assets of Abraxas.

The First Lien Notes indenture provides, among other things, that Abraxas may not, and may not cause or permit the Restricted Subsidiaries, to, directly or indirectly, create or otherwise cause to permit to exist or become effective any encumbrance or restriction on the ability of such subsidiary to pay dividends or make distributions on or in respect of its capital stock, make loans or advances or pay debts owed to Abraxas or any other Restricted Subsidiary, guarantee any indebtedness of Abraxas or any other Restricted Subsidiary or transfer any of its assets to Abraxas or any other Restricted Subsidiary except in certain situations as described in the First Lien Notes indenture.

Second Lien Notes. In December 1999, Abraxas and Canadian Abraxas consummated an Exchange Offer (see Note 2) whereby $269,699,000 of the Old Notes were exchanged for $188,778,000 of new Second Lien Notes, and 16,078,990 shares of Abraxas common stock and contingent value rights. See Note 6. An additional $5,000,000 of the Second Lien Notes were issued in payment of fees and expenses.

Interest on the Second Lien Notes is payable semi-annually in arrears on May 1 and November 1, commencing May 1, 2000. The Second Lien Notes are redeemable, in whole or in part, at the option of Abraxas and Canadian Abraxas on or after December 1, 2000, at the redemption prices set forth below, plus accrued and unpaid interest to the date of redemption, if redeemed during the 12-month period commencing on December 1 of the years set forth below:

Year                                         Percentage

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

The Second Lien Notes are senior indebtedness of Abraxas and Canadian Abraxas and are secured by a second lien on substantially all of the crude oil and natural gas properties of Abraxas and Canadian Abraxas and the shares of Grey Wolf owned by Abraxas and Canadian Abraxas. The Second Lien Notes are unconditionally guaranteed on a senior basis, jointly and severally, by Sandia and Wamsutter. The guarantees are secured by substantially all of the crude oil and natural gas properties of the guarantors. The Second Lien Notes are, however, effectively subordinated to the First Lien Notes and related guarantees to the extent the value of the collateral securing the Second Lien Notes and related guarantees and the First Lien Notes and related guarantees is insufficient to pay both the Second Lien Notes and the First Lien Notes.

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

The Second Lien Notes indenture contains certain covenants that limit the ability of Abraxas and Canadian Abraxas and certain of their subsidiaries,

including the guarantors of the Second Lien Notes (the "Restricted Subsidiaries") to, among other things, incur additional indebtedness, pay dividends or make certain other restricted payments, consummate certain asset sales, enter into certain transactions with affiliates, incur liens, merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the assets of Abraxas or Canadian Abraxas.

The Second Lien Notes indenture provides, among other things, that Abraxas and Canadian Abraxas may not, and may not cause or permit the Restricted Subsidiaries, to, directly or indirectly, create or otherwise cause to permit to exist or become effective any encumbrance or restriction on the ability of such subsidiary to pay dividends or make distributions on or in respect of its capital stock, make loans or advances or pay debts owed to Abraxas, Canadian Abraxas or any other Restricted Subsidiary, guarantee any indebtedness of Abraxas, Canadian Abraxas or any other Restricted Subsidiary or transfer any of its assets to Abraxas, Canadian Abraxas or any other Restricted Subsidiary except in certain situations as described in the Second Lien Notes indenture.

The fair value of the Old Notes, First Lien Notes and Second Lien Notes was approximately $235.2 million as of December 31, 2000. The Company has approximately $250,000 of standby letters of credit and a $10,000 performance bond open at December 31, 2000. Approximately $261,000 of cash is restricted and in escrow related to certain of the letters of credit and the bond.

Extraordinary Item

In June 2000, the Company retired $3.5 million of the Old Notes and $3.6 million of the Second Lien Notes at a discount of $1.7 million.

6. Stockholders' Equity

Common Stock

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

Once the Rights become exercisable, each Right entitles the holder, other than the acquiring person, to purchase for $40 a number of shares of the Company's common stock having a market value of two 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

Contingent Value Rights ("CVRs")

As part of the Exchange Offer consummated by the Company in December 1999 (see Note 2), Abraxas issued contingent value rights or CVRs, which entitled the holders to receive up to a total of 105,408,978 of Abraxas common stock under certain circumstances as defined. On May 21, 2001, Abraxas may be required to issue additional shares to the holders of the CVRs . The actual number of shares issued will depend on the average market price of Abraxas common stock over a defined period. Any future issuance of common stock will result in a transfer from Additional Paid In Capital to Common Stock. The CVRs will terminate if the market price of Abraxas common stock exceeds certain prices for a period of 30 trading days during any 45 day consecutive trading day period prior to the expiration date. The target price on a given date will equal $5.03 plus daily interest at an annual rate of 11.5% from November 1, 1999. The target price on May 21, 2001 is $5.97. As of December 31, 2000, based on the Abraxas common stock market price, CVR holders would have been entitled to receive approximately 9.5 million shares. As of March 22, 2001, based on the Abraxas Common Stock market price, CVR holders would be entitled to receive approximately 3.3 million shares.

Treasury Stock

In March 1996, the Board of Directors authorized the purchase in the open market of up to 500,000 shares of the Company's outstanding common stock, the aggregate purchase price not to exceed $3,500,000. During the year ended December 31, 1998, 136,255 shares with an aggregate cost of $980,000 were purchased. During the year ended December 31, 1999 the Company did not purchase any shares of its common stock for treasury stock. During the year ended December 31, 2000, 38,800 shares with an aggregate cost of $78,000 were purchased.

7. Stock Option Plans and Warrants

Stock Options

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

The Company's various stock option plans have authorized the grant of options to management personnel and directors for up to approximately 4.7 million shares of the Company's common stock. All options granted have ten year terms and vest and become fully exercisable over three to four years of continued service at 25% to 33% on each anniversary date. At December 31, 2000 approximately 547,800 options remain available for grant.

Pro forma information regarding net income (loss) and earnings (loss) per share is required by SFAS 123, "Accounting for Stock-Based Compensation", which also requires that the information be determined as if the Company has accounted for its employee stock options granted subsequent to December 31, 1995 under the fair value method prescribed by that SFAS. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for 1998, 1999, and 2000, : risk-free interest rates of 6.25%, 6.25% and 6.25%, respectively; dividend yields of -0-%; volatility factors of the expected market price of the Company's common stock of .667, .928 and .916, respectively; and a weighted-average expected life of the option of ten years.

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

For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting period. The Company's pro forma information follows:

                                                                1998           1999          2000

(2) In March 1999, the Company amended the exercise price to $2.06 per share on all options with an existing exercise price greater than $2.06. See Note 1 General and Administrative (Stock-based compensaation).

Stock Awards

In addition to stock options granted under the plans described above, the Long-Term Incentive Plan also provides for the right to receive compensation in cash, awards of common stock, or a combination thereof. In 1998 and 1999, the Company made direct awards of common stock of 18,263 shares and 18,932 shares, respectively, at weighted average fair values of $5.13 and $5.09 per share, respectively. The Company recorded compensation expense of $135,900 and $37,900 for the years ended December 31, 1998 and 1999 respectively. There were no awards in 2000.

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 1998, 1999, and 2000, the Company made direct awards of common stock of 4,838 shares; 3,314 shares and 12,753 shares, respectively, at weighted average fair values of $14.75, $4.38 and $0.94 per share, respectively.

During 1998 each of the seven eligible directors were granted an option to purchase 2,000 common shares at $7.44 and 3,000 common shares at $5.56. An additional option was granted to an eligible director to purchase 4,000 common shares at $7.44.

In December 1999 a new board was appointed in connection with the Company's Exchange Offer, each of the four new eligible directors were granted options for 75,000 common shares at $0.97.

Stock Warrants and Other

In 2000, the Company committed to issue 950,000 warrants in conjunction with a consulting agreement. Each is exercisable for one share of common stock at an exercise price of $3.50 per share. These warrants have a four-year term beginning July 1, 2000. The Company recorded approximately $219,000 of compensation expense which is included in Other expense.

At December 31, 2000, the Company has approximately 62,572,000 shares reserved for future issuance for conversion of its stock options, warrants, Contingent Value Rights, and incentive plans for the Company's directors and employees.

At December 31, 2000, the Company had, subject to the limitation discussed below, $101,800,000 of net operating loss carryforwards for U.S. tax purposes. These loss carryforwards will expire from 2001 through 2020 if not utilized. At December 31, 2000, the Company had approximately $11,400,000 of net operating loss carryforwards for Canadian tax purposes. These carryforwards will expire from 2001 through 2020 if not utilized.

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 the U.S. net operating loss carryforwards generated prior to December 31, 1991 of $4,909,000 will be limited to approximately $235,000 per year.

During 1992, the Company acquired 100% of the common stock of an unrelated corporation. The use of net operating loss carryforwards of the acquired corporation of $257,000 acquired in the acquisition are limited to approximately $115,000 per year.

As a result of the issuance of additional shares of common stock for acquisitions and sales of common stock, an additional ownership change under
Section 382 occurred in October 1993. Accordingly, it is expected that the use of all U.S. net operating loss carryforwards generated through October 1993
(including those subject to the 1991 and 1992 ownership changes discussed above)
of $8,295,000 will be limited as described above and in the following paragraph.

An ownership change under Section 382 occurred in December 1999, following the issuance of additional shares, as described in Note 5. It is expected that the annual use of U.S. net operating loss carryforwards subject to this Section 382 limitation will be limited to approximately $363,000, subject to the lower limitations described above. Future changes in ownership may further limit the use of the Company's carryforwards.

The annual Section 382 limitation may be increased during any year, within 5 years of a change in ownership, in which built-in gains that existed on the date of the change in ownership are recognized.

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 $36,134,000 and $34,763,000 for deferred tax assets at December 31, 1999 and 2000, respectively.

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

9. Related Party Transactions

Accounts receivable - Other and Other assets includes approximately $220,000 and $268,000 as of December 31, 1999 and 2000, respectively, representing amounts due from officers and stockholders relating primarily to joint interest billings on properties which the Company operates and advances made to employees.

At December 31, 2000, the Company owns approximately 49% of Grey Wolf. The Company's President, as well as certain directors, directly own approximately 13% of Grey Wolf. Additionally the Company's President owns options to purchase up to 91,000 shares of Grey Wolf capital stock at an exercise price of CDN$3.42 per share, and certain of the Company's directors own options to purchase in the aggregate up to 120,000 shares of Grey Wolf capital stock at an exercise price of CDN$2.00 per share. Grey Wolf currently has approximately 12,700,000 shares of capital stock outstanding. See Note 18.

Grey Wolf owns a 10% interest in the Canadian Abraxas oil and gas properties and the Canadian Abraxas gas processing plants acquired by Canadian Abraxas in November 1996 and manages the operations of Canadian Abraxas, pursuant to a management agreement between Canadian Abraxas and Grey Wolf. Under the management agreement, Canadian Abraxas reimburses Grey Wolf for reasonable costs or expenses attributable to Canadian Abraxas and for administrative expenses based upon the percentage that Canadian Abraxas' gross revenue bears to the total gross revenue of Canadian Abraxas and Grey Wolf. Amounts paid under this agreement were $1.5 million, $2.3 million and $2.5 million for the years ended December 31, 1998, 1999 and 2000, respectively.

Wind River Resources Corporation ("Wind River"), all of the capital stock of which is owned by the Company's President owns a twin-engine airplane. The airplane is available for business use by the employees of Abraxas from time to time at Wind River's cost. Abraxas paid Wind River a total of $302,000, $336,000 and $336,000 in 1998, 1999 and 2000 respectively.

For the years ended December 31, 1998 and 1999 none of the shares issuable in connection with stock options, warrants or CVRs are included in diluted shares. Inclusion of these shares would be antidilutive due to losses incurred in those years. Had losses not been incurred, 48,400 shares and 68.2 million shares would have been included for the years ended December 31, 1998 and 1999, respectively.

13. Benefit Plans

The Company has a defined contribution plan (401(k)) covering all eligible employees of the Company. During 1998 the Company contributed 10,329 shares of its common stock held in the treasury to the Plan and recorded the fair value of $76,847 as compensation expense. The Company did not contribute to the plan in 1999 or 2000. The employee contribution limitations are determined by formulas which limit the upper one-third of the plan members from contributing amounts that would cause the plan to be top-heavy. The employee contribution is limited to the lesser of 20% of the employee's annual compensation or $10,000.

14. Summary Financial Information of Canadian Abraxas Petroleum Ltd.

The following is summary financial information of Canadian Abraxas, a wholly owned subsidiary of the Company.

The Company has not presented separate financial statements and other disclosures concerning Canadian Abraxas because management has determined that such information is not material to the holders of the Old Notes, the First Lien Notes and the Second Lien Notes.

15. Business Segments

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

In 2000, two customers accounted for approximately 26% of oil and natural gas production revenue, three customers accounted for approximately 59% of United States revenue and two customers accounted for approximately 36% of revenue in Canada. In 1999, three customers accounted for approximately 58% of oil and natural gas production revenues. In 1998, four customers accounted for approximately 58% of oil and natural gas production revenues and gas processing revenues.

The Company operates in one segment. Business segment information about the Company's 1998 operations in different geographic areas is as follows:

16. Commodity Swap Agreements

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

In November 1996, the Company assumed swap arrangements extending through October 2001 with a counterparty involving various quantities and fixed prices. These swap arrangements provided that the Company make payments to the

F-26

counterparty to the extent the market prices, determined based on the price for crude oil on the NYMEX and the Inside FERC, Tennessee Gas Pipeline Co. Texas (Zone O) price for natural gas exceeded certain fixed prices and for the counterparty to make payments to us to the extent the market prices were less than such fixed prices. The Company accounted for the related gains or losses in crude oil and natural gas revenue in the period of the hedged production. These swap arrangements terminated in January 1999 and the Company was paid $750,000 by the counterparty for such termination. This amount is included in Other Revenue in the accompanying financial statements.

In March 1998, the Company entered into a costless collar hedge agreement with Enron Capital and Trade Resources Corp. for 2,000 Bbls of crude oil per day with a floor price of $14.00 per Bbl and a ceiling price of $22.30 per Bbl for crude oil on the NYMEX. The agreement was effective April 1, 1998 and extended through March 31, 1999. Under the terms of the agreement the Company was paid when the average monthly price for crude oil on the NYMEX was below the floor price, and the Company paid the counterparty when the average monthly price exceeded the ceiling price. For the year ended December 31, 1999 the Company realized a loss of $1.8 million on this agreement, which is accounted for in Crude Oil and Natural Gas Revenue. The Company has also entered into a costless collar hedge agreement with Barrett Resources Corporation ("Barrett") for the period November 1999 through October 2000. This agreement consisted of a swap for 1,000 Bbls per day with the Company being paid $20.30 and paying NYMEX calendar month average, and an additional 1,000 barrels per day with a floor price of $18.00 per Bbl and a ceiling of $22.00 per Bbl. The Company realized a loss from hedges of $20.2 million for the year ended December 31, 2000, which is accounted for in Oil and Gas Production Revenue.

At year end 2000 Barrett has a swap call on either 1,000 Bbls of crude oil or 20,000 MMBtu of natural gas per day at Barrett's option at fixed prices ($18.00 for crude oil or $2.60 to $2.95 for natural gas) through October 31, 2002. As of December 31, 2000, the fair market value of the remaining fixed price Hedge Agreement is a liability of approximately $38 million, of which $27 million is expected to be charged to revenues in 2001 and $11 million in 2002. See Note 1, New Accounting Pronouncement regarding adoption of SFAS 133 effective January 1, 2001.

17. Proved Property Impairment

In 1998 and 1999, respectively, the Company recorded write-downs of its proved crude oil and natural gas properties of approximately $61,224,000 and $19,100,000 under the ceiling limitation prescribed for companies following the full cost method of accounting for its oil and gas properties. The write-down in 1999 was related to the Company's Canadian oil and gas properties and the 1998 write-down was related to the Company's United States oil and gas properties. The write down in 1998 was due primarily to a decrease in spot market prices for the Company's crude oil and natural gas. The write-down in 1999 was due to a downward revision of the Company's proved reserves in Canada. Under full cost accounting rules, the net capitalized costs of oil and gas properties, less related deferred taxes, are limited by country, to the lower of unamortized cost or the cost ceiling as discussed in Note 1. The risk that the Company will be required to write-down the carrying value of its crude oil and natural gas properties increases when crude oil and natural gas prices are depressed or volatile. Depending on future prices, further impairment of the Company's crude oil and natural gas properties may be required.

18. Subsequent Event

On January 19, 2001, the Company announced that it is in discussions concerning a stock for stock acquisition of the remaining 51% of Grey Wolf that it does not currently own.

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, 1998, 1999, and 2000. The Company's management emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise than those of producing oil and gas properties. Accordingly, the estimates are expected to change as future information becomes available. The estimates have been prepared by independent petroleum reserve engineers.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves

The following disclosures concerning the standardized measure of future cash flows from proved crude oil and natural gas reserves are presented in accordance with SFAS 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, 2000, adjusted for fixed and determinable escalations, to the estimated future production of year-end proved reserves. Future cash inflows were reduced by estimated future production and development costs based on year-end costs to determine pre-tax cash inflows. Future income taxes were computed by applying the statutory tax rate to the excess of pre-tax cash inflows over the tax basis of the properties. Operating loss carryforwards, tax credits, and permanent differences to the extent estimated to be available in the future were also considered in the future income tax calculations, thereby reducing the expected tax expense.

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