In this respect, the Midland Board concluded, following extensive discussions with Midland's management and among the directors, that the transactions contemplated by the Merger Agreement provided the best means for holders of Midland Common Stock to maximize the value of their holdings. Property Characteristics. The level of operational control and the location of the Vista Partnership's properties, the long life nature of the Vista Partnership's properties, the relative amount of oil properties versus gas properties and the amount of development potential of Midland's properties. Financial. Information concerning the financial performance, financial condition, business operations and prospects of each of the Vista Partnership and Midland; Efficiencies. The opportunities for operating efficiencies that are anticipated to result from the Merger, particularly in terms of the integration of office facilities, technical personnel and support functions; Management. The management strengths of the Vista Partnership in building equity value and the experience of Natural Gas Partners II, L.P. and Natural Gas Partners III, L.P. (collectively, "NGP"), which will be the largest stockholder of Vista upon consummation of the Merger, in assisting their portfolio companies execute their business plans. Access to Capital. Improvements in the combined company's ability to access the capital markets and otherwise increase its financial flexibility; 7 11 Exchange Ratio/Market Price. The exchange ratio of shares of Vista Common Stock issuable for shares of Midland Common Stock upon consummation of the Merger (the "Midland Conversion Number") and recent trading prices for Midland Common Stock and the belief of the Midland Board, following analyses and discussions with Midland's management and among the directors, that the Midland Conversion Number was fair and in the best interests of the Midland stockholders; and Fairness Opinion. The opinion of Dain Rauscher Wessels, a division of Dain Rauscher Incorporated, to the effect that the Merger is fair to the holders of Midland Common Stock from a financial point of view. The Midland Board believes that the Merger offers the opportunity to create a combined company that will have greater competitive strengths, business opportunities, financial resources and flexibility than Midland could achieve alone. OPINION OF MIDLAND'S FINANCIAL ADVISOR At the May 21, 1998 meeting of the Midland Board held to consider and vote on entering into the Merger Agreement, the Midland Board considered the presentation made by the representatives of Dain Rauscher Wessels, a division of Dain Rauscher Incorporated, regarding its preliminary valuation and financial analysis of the Merger, that was confirmed by its final valuation and financial analysis presented at a meeting of the Midland Board on June 25, 1998, and in writing with delivery of its written fairness opinion on June 30, 1998, that the Merger was fair from a financial point of view to the holders of Midland Common Stock. For information on the assumptions made, matters considered and limits of the review by Dain Rauscher Wessels, and for information concerning compensation paid or payable to such firm in connection with the Merger, see "The Merger -- Opinion of Midland's Financial Advisor." Midland Stockholders are urged to read in its entirety the full text of the opinion of Dain Rauscher Wessels, which is set forth as Appendix D-1 and D-2 to this Proxy Statement/Prospectus. INTERESTS OF CERTAIN PERSONS In considering the recommendation of the Midland Board, stockholders should be aware that certain members of the boards of directors and certain executive officers of Vista and Midland have interests in the Merger separate from their interests as stockholders. Such interests include the following: (i) the Midland Board shall designate one individual to serve on the Vista Board; (ii) Vista will enter into indemnification agreements with each of the directors and officers of Vista; (iii) Vista will enter into indemnification agreements with each of the directors and officers of Midland; (iv) pursuant to the terms of the Midland Exchange Agreement, Sam R. Brock, a director of Midland, Darrell M. Dillard, a director of Midland, Robert R. Donnelly, president and a director of Midland, Wayne M. Whitaker, a director of Midland, John Q. Adams, an advisory director of Midland, and Marilyn D. Wade, corporate secretary of Midland, shall exchange each Midland Exchange Stock Option for a Vista Warrant that is exercisable for that whole number of shares of Vista Common Stock (to the nearest whole share) equal to the product of (x) .725 times (y) the number of shares of Vista Common Stock into which the shares of Midland Common Stock subject to such Midland Exchange Stock Option would be converted pursuant to the Merger; (v) concurrently with execution of the Merger Agreement, Midland obtained written resignations from each of its officers and directors effective as of the Effective Time and Midland entered into termination agreements with Howard E. Ehler and Marilyn D. Wade effective as of the Effective Time; (vi) concurrently with execution of the Merger Agreement, Midland entered into a Settlement Agreement with Deas H. Warley; and (vii) concurrently with execution of the Merger Agreement, Deas H. Warley and Marilyn D. Wade entered into a Release and Hold Harmless Agreement. See "The Merger -- Interests of Certain Persons in the Merger." ACCOUNTING TREATMENT The Merger and the Midland Exchange will be accounted for as a purchase of Midland by Vista for financial accounting purposes. See "The Merger -- Accounting Treatment." 8 12 MATERIAL TAX CONSEQUENCES The Merger has been structured to qualify as a reorganization under the Code. Midland received an opinion from Arthur Andersen LLP to the effect that (i) The Merger will constitute a reorganization within the meaning of the Code. (ii) Vista, Midland and Merger Sub will all be "a party to a reorganization" under the Code. (iii) No gain or loss will be recognized by the stockholders of Midland on the receipt of Vista Common Stock solely in exchange for Midland Common Stock surrendered pursuant to the plan of reorganization. The payment of cash in lieu of fractional share interests of Vista Common Stock will be treated as if each fractional share is distributed as part of the exchange and then redeemed by Vista. Subject to the conditions and limitations of Section 302(a) of the Code, these cash payments will be treated as having been received as distributions in full payment in exchange for the fractional share of Vista Common Stock. Any gain or loss recognized upon such exchange will be capital gain or loss provided the fractional share would constitute a capital asset in the hands of the exchanging stockholder. The Vista Exchange should constitute a transfer to a controlled corporation within the meaning of Section 351 of the Code. Accordingly, under current law, no gain or loss should be recognized upon the exchange for Vista Common Stock, except that (1) any gain inherent in the exchange should be recognized to the extent of the fair market value of any Vista Warrants received and (2) gain or loss should be recognized equal to the difference between any cash received in lieu of fractional share interest and the tax basis in the fractional share deemed to have been redeemed in the exchange. See "The Merger -- Material Income Tax Consequences." DISSENTERS' RIGHTS Under Texas law, holders of Midland Common Stock will not be entitled to any dissenters' rights in connection with the Merger. COMPARISON OF STOCKHOLDER RIGHTS Rights of stockholders of Midland are currently governed by the Texas Business Corporation Law, the Articles of Incorporation of Midland and the Bylaws of Midland. Upon consummation of the Merger, Midland stockholders will become stockholders of Vista and their rights as Vista stockholders will be governed by the Delaware General Corporation Law, the Certificate of Incorporation of Vista and the Bylaws of Vista. There are various differences between the rights of Midland stockholders and the rights of Vista stockholders. See "Comparison of Stockholder Rights" and "Description of Vista Capital Stock." RISK FACTORS In evaluating the Merger, stockholders should take into account the following risk factors relating to the Merger, Midland, the Vista Partnership and Vista, and their respective businesses, which risk factors are discussed at greater length under the caption "Risk Factors." - forward-looking statements are contained in this Proxy Statement/Prospectus and, although Vista and Midland believe they are based on reasonable assumptions, no assurances can be given that actual results may not differ from such forward-looking statements; - the merger consideration to be received by the stockholders of Midland is fixed and will not be adjusted due to market conditions or in the event of any fluctuations in the price of the Midland Common Stock; - prices for oil and gas production and the costs of acquiring, finding, developing and producing such products are volatile; - the Vista Partnership's and Midland's reserve information is based upon estimates of proved reserves and future net cash flows, which may not prove to be accurate; 9 13 - Vista's success will depend upon replacement of reserves; - Vista's success will require substantial capital requirements; - Vista will have substantial indebtedness upon consummation of the Merger; - drilling for oil and gas involves a high degree of risk; - Vista's success will depend upon successful acquisitions and divestitures of properties; - the failure of Midland stockholders to approve the Merger Agreement would likely cause Midland to further reduce personnel, consider the sale of properties it would prefer not to sell at current market prices to reduce debt, and possibly take other actions that the Midland Board does not presently consider to be as advantageous to the Midland stockholders as the Merger; - substantially all of Vista's oil and gas properties will be mortgaged to secure borrowings from its lenders; - Vista's success will depend upon key personnel; - a majority of Vista's capital stock will be controlled by a single stockholder; - oil and gas operations involve risks that may not be fully insured; - governments regulate the oil and gas industry extensively; - oil and gas production, development and exploration activities are highly competitive; - certain Vista stockholders will have the right to require Vista to register their Vista Common Stock; - restrictions will exist on the payment of dividends under Vista's Credit Facility (as defined herein); - Vista Common Stock will not have a public market before the Merger and no assurances can be given that an active public market for such stock will develop or be sustained; and - the price of Vista Common Stock may be volatile. 10 14 SUMMARY SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF THE VISTA PARTNERSHIP The following table sets forth selected consolidated financial information of the Vista Partnership for the six months ended June 30, 1998 and 1997, and for the years ended December 31, 1997 and 1996 and for the period from inception (September 21, 1995) to December 31, 1995.

(2) The Vista Partnership believes that EBITDAEX may provide additional information about the Vista Partnership's discretionary cash flow and its ability to meet its future requirements for debt service, capital expenditures and working capital. EBITDAEX is a financial measure commonly used in the oil and gas industry and should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating activities or any other measures of financial performance presented in accordance with generally accepted accounting principles or as a measure of a company's profitability or liquidity. Because EBITDAEX excludes some, but not all, items that affect net income and these measures may vary among companies, the EBITDAEX data presented above may not be comparable to similarly titled measures of other companies. EBITDAEX (as used herein) is calculated by adding depletion, depreciation and amortization, and exploration costs to operating income. Exploration costs represent discretionary cost items. Therefore, exploration costs have been added back in order to present a discretionary cash flow for the Vista Partnership. Interest includes accrued interest expense and amortization of deferred financing costs. (3) For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as income (loss) before taxes plus fixed charges. Fixed charges consist of interest expense. For the six months ended June 30, 1998, earnings were insufficient to cover fixed charges by $0.5 million. 11 15 SUMMARY SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF MIDLAND The following table sets forth selected consolidated financial information of Midland for the six months ended June 30, 1998 and 1997, and for each of the five fiscal years in the period ended December 31, 1997.

(b) Gain (loss) on sale of properties was principally composed of the loss on the sale of Midland's former office facilities in Midland, Texas, in 1995 and a gain on the sale of a working interest in an oil and gas property to Summit Petroleum Corporation in 1994. In 1997, gains were realized primarily from the sale of oil and gas properties. (c) In 1994, there was other income from the settlement of litigation regarding a former property operator of $120,090.

The unaudited pro forma statements of operations do not consider the effects of the cost reduction plans of management to be implemented after closing. Management expects to reduce lease operating expenses by approximately $210,000 on an annual basis for efficiencies to be realized through economies of scale in common operating locations and reductions of certain field personnel. In addition, management expects to reduce general and administrative expenses by approximately $1,475,000 on an annual basis from the elimination of redundant personnel, lease space and other corporate services. In accordance with Securities and Exchange Commission regulation, none of these anticipated cost reductions have been reflected in the accompanying pro forma statements of operations. 13 17 RISK FACTORS Stockholders should carefully review the following factors together with the other information contained in this Proxy Statement/Prospectus prior to voting on the proposal herein. CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION This Proxy Statement/Prospectus includes forward-looking statements. All statements other than statements of historical fact included in this Proxy Statement/Prospectus including, without limitation, the statements under "Summary," "The Vista Partnership -- Management's Discussion and Analysis of Financial Condition and Results of Operations of the Vista Partnership," "The Vista Partnership -- Business and Properties of the Vista Partnership," "Midland -- Management's Discussion and Analysis of Financial Condition and Results of Operations of Midland" and "Midland -- Business and Properties of Midland" are forward-looking statements. Although the Vista Partnership and Midland believe their respective expectations are based on reasonable assumptions, no assurance can be given that actual results may not differ materially from those in the forward-looking statements. Important factors that could cause actual results to differ materially from the expectations of the Vista Partnership and Midland include, among other things, the prices received or demand for oil and gas, the uncertainty of reserve estimates, operating hazards, competition and the effects of governmental and environmental regulation, conditions in the capital markets and equity markets, and the ability of Vista to achieve the goals described in "Vista -- Strengths and Strategies," as well as other factors discussed in this Proxy Statement/Prospectus. FIXED MERGER CONSIDERATION FOR MIDLAND STOCKHOLDERS Stockholders of Midland should consider that the merger consideration will not be adjusted in the event of an increase or decrease in the market price of Midland Common Stock. Holders of Midland Common Stock will receive one share of Vista Common Stock for each share of Midland Common Stock held. Stockholders of Midland are urged to obtain current stock market quotations for Midland Common Stock. EFFECT OF VOLATILE PRODUCT PRICES AND MARKETS The future financial condition and results of operations of Vista will depend upon the prices received for oil and gas production and the costs of acquiring, finding, developing and producing reserves. Prices for oil and gas are subject to fluctuations in response to relatively minor changes in supply, demand, market uncertainty and a variety of additional factors that are beyond the control of Vista. These factors include worldwide political instability (especially in the Middle East and other oil-producing regions), the foreign supply of oil and gas, the price of foreign imports, the level of consumer product demand, government regulations and taxes, the price and availability of alternative fuels and the overall economic environment. A substantial or extended decline in oil or gas prices would have a material adverse effect on Vista's financial position, results of operations, quantities of oil and gas that may be economically produced and access to capital. The sale of oil and gas production of Vista depends upon a number of factors beyond its control, including the availability and capacity of transportation and processing facilities. A substantial portion of Vista's oil and a significant portion of its gas is transported through gathering systems and pipelines that are not owned by Vista. 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 oil and gas shippers that may or may not have priority transportation agreements. Vista has not experienced any material inability to market its proved reserves of oil or gas as a result of limited access to transportation space. If transportation space is materially restricted or is unavailable in the future, Vista's ability to market its oil or gas could be impaired and cash flow from the affected properties could be reduced, which could have a material adverse effect on Vista's financial condition or results of operations. See "-- Governmental Regulation and Environmental Matters." Oil and gas prices have historically been volatile and are likely to continue to be volatile in the future. Such volatility makes it difficult to estimate the value of producing properties for acquisition and to budget and project the financial return on exploration and development projects involving producing properties. In 14 18 addition, unusually volatile prices often disrupt the market for oil and gas properties, as buyers and sellers have more difficulty agreeing on the purchase price of properties. In particular, from January 2, 1997 to September 11, 1998, the prices of crude oil have ranged from a high of $26.82 per Bbl to a low of $11.56 per Bbl and gas prices have ranged from a high of $3.68 per Mcf to a low of $1.70 per Mcf, in each case as the reported NYMEX Daily Prompt Month Closing Price. The Vista Partnership engages in hedging activities with respect to a portion of its projected oil and gas production through a variety of financial arrangements designed to protect against price declines, including swaps, collars and futures agreements and Vista expects to continue to do so. To the extent that Vista engages in such activities, it may be prevented from realizing the benefits of price increases above the levels reflected in such hedges. RELIANCE ON ESTIMATES OF PROVED RESERVES AND FUTURE NET CASH FLOWS Information relating to the Vista Partnership's and Midland's proved oil and gas reserves set forth in this Proxy Statement/Prospectus is based upon engineering estimates. Reserve engineering is a subjective process of estimating the recovery from underground accumulations of oil and gas that cannot be measured in an exact manner, and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Estimates of economically recoverable oil and gas reserves and of future net cash flows necessarily depend upon a number of variable factors and assumptions, such as historical production from the area compared with production from other producing areas, the assumed effects of regulations by governmental agencies and assumptions concerning future oil and gas prices, future operating costs, severance and excise taxes, development costs and workover and remedial costs, all of which may in fact vary considerably from actual results. Because all reserve estimates are to some degree speculative, the quantities of oil and gas that are ultimately recovered, production and operation costs, the amount and timing of future development expenditures, and future oil and gas sales prices may all vary from those assumed in these estimates. Those variances may be material. In addition, different reserve engineers may make different estimates of reserve quantities and cash flows based upon the same available data. The present value of estimated future net cash flows should not be construed as the current market value of the estimated proved oil and gas reserves attributable to the Vista Partnership's or Midland's properties. In accordance with applicable requirements of the Commission, the estimated discounted future net cash flows from proved reserves are generally based on prices and costs as of the date of the estimate, whereas actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by factors such as the amount and timing of actual production, supply and demand for oil and gas, curtailments or increases in consumption by gas purchasers and changes in governmental regulations or taxation. The timing of actual future net cash flows from proved reserves, and thus their actual present value, will be affected by the timing of both the production and the incurrence of expenses in connection with development and production of oil and gas properties. In addition, the 10% discount factor, which is required by the Commission to be used to calculate discounted future net cash flows for reporting purposes, is not necessarily the most appropriate discount factor based on interest rates in effect from time to time and risks associated with the Vista Partnership's or Midland's business or the oil and gas industry in general. REPLACEMENT OF RESERVES Vista's future success will depend on its ability to find, develop or acquire additional oil and gas reserves that are economically recoverable. The proved reserves of Vista will generally decline as reserves are depleted, except to the extent that Vista conducts successful exploration or development activities or acquires properties containing proved reserves, or both. There can be no assurance that Vista's planned development and exploration projects and acquisition activities will result in significant additional reserves or that Vista will have success drilling productive wells at low finding and development costs. Furthermore, while Vista's revenues may increase if prevailing oil and gas prices increase significantly, Vista's finding costs for additional reserves could also increase. 15 19 SUBSTANTIAL CAPITAL REQUIREMENTS The Vista Partnership and Midland have made, and Vista will continue to make, substantial capital expenditures for the development, exploration, acquisition and production of oil and gas reserves. Historically, the Vista Partnership and Midland have financed these expenditures primarily with proceeds from bank borrowings, cash flow and private placements. The Vista Partnership and Midland respectively made capital expenditures (including expenditures for acquisitions) of $6.7 million and $3.8 million during 1996, $12.1 million and $4.1 million during 1997 and $1.7 million and $622,000 for the six months ended June 30, 1998. If revenues decrease as a result of lower oil and gas prices or operating difficulties, Vista may be limited in its ability to expend the capital necessary to undertake or complete its drilling program in future years. There can be no assurance that additional debt or equity financing or cash generated by operations will be available to meet these requirements. LEVERAGE Upon consummation of the Merger, Vista will have long-term indebtedness of approximately $28 million under its Amended and Restated Credit Agreement, dated August 15, 1997, between the Vista Partnership and Union Bank of California (the "Credit Facility"). It is anticipated that Vista will incur additional indebtedness in the future to assist in financing its growth. Any delay in repayment or default on such debt could have an adverse effect on Vista and its stockholders. Vista's degree of leverage could have important consequences to the holders of the Vista Common Stock, including the following: (i) Vista's ability to obtain additional financing for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired in the future; (ii) a substantial portion of Vista's cash flow from operations must be dedicated to the payment of principal and interest on its indebtedness, thereby reducing the funds available to Vista for other purposes; (iii) Vista's borrowings under the Credit Facility will be at variable rates of interest, which will expose Vista to the risk of increased interest rates; (iv) Vista may be substantially more leveraged than certain of its competitors, which may place Vista at a competitive disadvantage; and (v) Vista's degree of leverage may limit its flexibility to adjust to changing market conditions, reduce its ability to withstand competitive pressures and make it more vulnerable to a downturn in general economic conditions or its business. DRILLING RISKS Drilling for oil and gas involves a high degree of risk. For any given well, there is no assurance that a reservoir will be encountered or, if encountered, will produce in commercial quantities. The cost of drilling, completing and operating wells is often uncertain, and drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, including, without limitation, unexpected drilling conditions, pressure or irregularities in formations, equipment failures or accidents, adverse weather conditions and shortages or delays in the delivery of equipment. Vista's future drilling activities may not be successful and, if unsuccessful, such failure will have an adverse effect on Vista's future results of operations and financial condition. While all drilling, whether development or exploratory, involves these risks, exploratory drilling involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons. Because of the percentage of Vista's capital budget devoted to exploratory projects, it is likely that Vista will continue to experience exploration and abandonment expenses. ACQUISITIONS AND DIVESTITURES Each of the Vista Partnership's and Midland's rapid growth in recent years has been largely the result of acquisitions of producing oil and gas properties. Vista's growth following full development of its existing property base could be impeded if it is unable to acquire additional oil and gas properties on a profitable basis. The success of any acquisition will depend on a number of factors, including the ability to estimate accurately the recoverable volumes of reserves, rates of future production and future net revenues attributable to reserves and to assess possible environmental liabilities. All of these factors affect whether an acquisition will ultimately generate cash flows sufficient to provide a suitable return on investment. Although Vista performs a 16 20 review of the properties it seeks to acquire that it believes is consistent with industry practices, such reviews are often limited in scope. Vista reviews its property base for the purpose of identifying non-strategic assets, the disposition of which would increase capital resources available for other activities and create organizational and operational efficiencies. Various factors could materially affect the ability of Vista to dispose of non-strategic assets, including the availability of purchasers willing to purchase the non-strategic assets at prices acceptable to Vista. EFFECT ON MIDLAND OF FAILURE TO OBTAIN STOCKHOLDER APPROVAL OF THE MERGER The Midland Board has considered various strategic alternatives to the Merger including the issuance of equity or debt securities, the sale of assets, and the merger with, or acquisition of, another company. After exhaustively exploring such alternatives, the Midland Board has determined that the Merger is in the best interests of the Midland stockholders. Midland has devoted substantial management and capital resources in pursuing the Merger for the reasons set forth under "The Merger -- Recommendation of Midland's Board of Directors; Midland's Reasons for the Merger." Further, in an effort to achieve operating efficiencies, Midland has made certain personnel reductions and operational changes. As a result of these events and actions and the current reduced level of oil and gas prices, the failure of the Midland stockholders to approve the Merger Agreement would likely cause Midland to further reduce personnel, consider the sale of properties it would prefer not to sell at current market prices to reduce debt, and possibly take other actions which the Midland Board does not presently consider to be as advantageous to the Midland stockholders as the Merger. TITLE TO PROPERTIES Substantially all of Vista's oil and gas properties will be mortgaged to secure borrowings under the Credit Facility. In the event of Vista's default under certain provisions of the Credit Facility, Vista's ownership interest in these properties may by subject to foreclosure by the lender. DEPENDENCE ON KEY PERSONNEL Vista will depend to a large extent on the services of C. Randall Hill, Steven D. Gray and R. Cory Richards. Vista has key man life insurance on Messrs. Hill and Gray in the amount of $1 million for each officer. The loss of the services of Messrs. Hill, Gray or Richards could have a material adverse effect on Vista's ability to achieve its goals. CONTROL BY PRINCIPAL STOCKHOLDER After consummation of the Merger, Vista's principal stockholder will be NGP. As of September 11, 1998, NGP owned approximately 71% of the outstanding Partnership Interests and approximately 79% of the outstanding shares of GP Common Stock. Upon consummation of the Merger, NGP will own approximately 52% of the outstanding shares of Vista Common Stock. Accordingly, NGP will be able to control the outcome of stockholder votes, including votes concerning the election of directors, the adoption or amendment of provisions in Vista's Certificate of Incorporation or Bylaws and the approval of mergers and other significant transactions. The existence of this level of ownership concentrated in a single stockholder makes it unlikely that any other holder of Vista Common Stock will be able to affect the management or direction of Vista. These factors may also have the effect of delaying or preventing a change in the management or voting control of Vista. OPERATING HAZARDS; LIMITED INSURANCE COVERAGE Vista's operations will be subject to hazards and risks inherent in drilling for and production and transportation of oil and gas, such as fires, natural disasters, explosions, encountering formations with abnormal pressures, blowouts, cratering, pipeline ruptures and spills, any of which can result in the loss of hydrocarbons, environmental pollution, personal injury claims and other damage to properties of Vista and others. These risks could result in substantial losses to Vista due to injury and loss of life, severe damage to and 17 21 destruction of property and equipment, pollution and other environmental damage and suspension of operations. As protection against operating hazards, the Vista Partnership and Midland have maintained and Vista expects to maintain insurance coverage against some, but not all, potential losses. The occurrence of an event that is not covered, or not fully covered, by insurance could have a material adverse effect on Vista's financial condition and results of operations. In addition, pollution and environmental risks generally are not fully insurable. The occurrence of an event that is not fully covered by insurance could have an adverse effect on Vista's financial condition and results of operations. GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS Vista's business will be regulated by certain local, state and federal laws and regulations relating to the exploration for, and the development, production, marketing, pricing, transportation and storage of, oil and gas. Vista's business will also be subject to extensive and changing environmental and safety laws and regulations governing plugging and abandonment, the discharge of materials into the environment or otherwise relating to environmental protection. As with any owner of property, Vista will also be subject to cleanup costs and liability for hazardous materials, asbestos or any other toxic or hazardous substance that may exist on or under any of its properties. The implementation of new, or the modification of existing, laws or regulations, including amendments to the Oil Pollution Act of 1990, as amended, or regulations which may be promulgated thereunder, could have a material adverse effect on Vista. The imposition of any such liabilities on Vista could have a material adverse effect on Vista's financial condition and results of operations. COMPETITION The oil and gas industry is highly competitive. Vista will encounter competition from other oil and gas companies in all areas of its operations, including the acquisition of producing properties. Vista's competitors include major integrated oil and gas companies and numerous independent oil and gas companies, individuals and drilling and income programs. Many of its competitors are large, well-established companies with substantially larger operating staffs and greater capital resources than Vista and which, in many instances, have been engaged in the energy business for a much longer time than Vista. Such companies may be able to pay more for productive oil and gas properties and exploratory prospects and to define, evaluate, bid for and purchase a greater number of properties and prospects than Vista's financial or human resources will permit. Vista's ability to acquire additional properties and to discover reserves in the future will be dependent upon its ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. YEAR 2000 COMPLIANCE Many currently installed computer systems and software products are coded to accept only two digit entries in the date code field. These date code fields will need to accept four digit entries to distinguish the 21st century dates from 20th century dates. As a result, computer systems and software used by many companies may need to be upgraded to comply with such "Year 2000" requirements. Although Vista does not expect that the cost of converting its computer system to comply with Year 2000 requirements will be material to its financial condition, and it does not currently anticipate any disruption in its operations as the result of any failure by Vista to be in compliance, there can be no assurance that Vista's upgraded system will contain all necessary software routines and programs necessary for the accurate calculation, display, storage and manipulation of data involving dates. Moreover, Vista cannot determine what effect, if any, the Year 2000 requirements will have on its vendors, customers, other businesses with which it conducts business and the numerous local, state, federal and other U.S. and foreign governmental entities by which it is regulated, governed or taxed. No assurance can be given that the computer systems and software of such entities will be Year 2000 compliant or that compliance costs or the impact of Vista's failure to achieve substantial Year 2000 compliance will not have a material adverse effect on Vista's financial position and results of operations. 18 22 SHARES ELIGIBLE FOR FUTURE SALE Vista believes that immediately after the Effective Time, in addition to the shares of Vista Common Stock being registered pursuant to this Proxy Statement/Prospectus, all of the 11,778,479 shares issued pursuant to the Vista Exchange will be eligible for resale under Rules 144 and 145 of the Securities Act. In addition, out of the shares of Vista Common Stock subject to this Proxy Statement/Prospectus, 1,621,918 shares will be subject to Rule 145 and will be eligible for resale thereunder. RESTRICTIONS ON DIVIDENDS Dividends will be paid on Vista Common Stock only if, as and when declared by the board of directors of Vista (the "Vista Board"). Vista's ability to pay dividends is limited by the terms of the Credit Facility and may be limited by terms of any future debt indentures and preferred stock. It is Vista's current intention to retain earnings to fund future growth and, therefore, Vista will not pay dividends. NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE Before consummation of the Merger, there has been no public market for the Vista Common Stock, and an active public market for the Vista Common Stock may not develop or be sustained. The market price for Vista Common Stock may be highly volatile depending on various factors, including the general economy, stock market conditions, announcements by Vista, its competitors and fluctuations in Vista's overall operating results. In addition, the stock market historically has experienced volatility that has affected the market price of securities of many companies and which has sometimes been unrelated to the operating performance of such companies. The market price of the Vista Common Stock could also be subject to significant fluctuations in response to variations in quarterly results of operations, changes in earnings estimates by analysts, governmental regulatory action, general trends in the industry and overall market conditions, and other factors. RISKS RELATING TO LOW-PRICED STOCK; POSSIBLE EFFECT OF "PENNY STOCK" RULES ON LIQUIDITY FOR VISTA'S SECURITIES If after the Merger the Vista Common Stock should cease to be listed on the ASE and if the Vista Common Stock is not relisted on a different exchange or on the Nasdaq National Market, then, the Vista Common Stock would become subject to Rule 15g-9 under the Exchange Act. This Rule (the "Penny Stock Rule") imposes additional sales practice requirements on broker-dealers that sell such securities to persons other than established customers and "accredited investors" (generally, individuals with a net worth in excess of $1,000,000 or annual incomes exceeding $200,000, or $300,000 together with their spouses). For transactions covered by Rule 15g-9, a broker-dealer must make a special suitability determination for the purchaser and have received the purchaser's written consent to the transaction prior to sale. Consequently, upon the occurrence of such an event, the application of such Rule may affect the ability of broker-dealers to sell Vista's securities and may affect the ability of purchasers to sell any of Vista's securities in the secondary market. The Commission has adopted regulations that define a "penny stock" to be any equity security that has a market price (as therein defined) of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require delivery, prior to any transaction in a penny stock, of a disclosure schedule prepared by the Commission relating to the penny stock market. Disclosure is also required to be made about sales commissions payable to both the broker-dealer and the registered representative and current quotations for the securities. Finally, monthly statements are required to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stock. The foregoing required penny stock restrictions will not apply to Vista Common Stock if Vista satisfies ASE requirements regarding continued listing or if the Vista Common Stock is listed on a different exchange or on the Nasdaq National Market. There can be no assurance that Vista Common Stock will qualify for exemption from the penny stock restrictions. In any event, even if Vista Common Stock were exempt from such restrictions, Vista would remain subject to Section 15(b)(6) of the Exchange Act, which gives the 19 23 Commission the authority to restrict any person from participating in a distribution of penny stock, if the Commission finds that such a restriction would be in the public interest. If Vista Common Stock were subject to the rules on penny stocks, the market liquidity for Vista Common Stock could be materially adversely affected. THE COMPANIES MIDLAND Midland is an independent oil and gas company engaged primarily in the exploration and development of domestic oil and gas. Midland's initial emphasis was on acquisition and exploitation of oil and gas properties. In 1995, Midland changed its emphasis to exploration, utilizing 3-D seismic technology. Although Midland's principal properties are located in Texas, Midland also owns working interest and minor royalty leasehold interests in developed and undeveloped oil and gas acreage in Illinois and Colorado. Midland had approximately 5.0 million BOE of total proved reserves at December 31, 1997 and PV10 of approximately $17.8 million. Oil reserves at year end 1997 were 2.7 million Bbls and natural gas reserves at year end 1997 were 13.9 Bcf. On a BOE basis, 67% of Midland's total proved reserves at December 31, 1997 are proved developed reserves. Midland operates 95% of its total proved reserves. The reserve-to-production ratio associated with Midland's proved reserves is 14 years on a BOE basis. THE VISTA PARTNERSHIP The Vista Partnership is a privately held independent oil and gas exploration and production company with operations and properties located in the Permian Basin of West Texas and Southeastern New Mexico and the onshore Gulf Coast region of South Texas. The Vista Partnership and its operating subsidiary, Vista Resources, Inc., were formed by management of the Vista Partnership and various affiliates of NGP in September 1995 to focus on acquisitions and exploitation drilling primarily in the Permian Basin of West Texas and Southeast New Mexico. The Vista Partnership had approximately 9.1 million BOE of total proved reserves at December 31, 1997 and PV10 of approximately $38.6 million. Oil reserves at year end 1997 were 7.2 million Bbls and natural gas reserves at year end 1997 were 11.3 Bcf. On a BOE basis, 52% of the Vista Partnership's total proved reserves at December 31, 1997 are proved developed reserves. The Vista Partnership operates 92% of its total proved reserves. The reserve-to-production ratio associated with the Vista Partnership's proved reserves is 14 years on a BOE basis. VISTA Vista is a newly formed Delaware corporation and wholly owned subsidiary of the Vista Partnership that has not, to date, conducted any significant activities other than those incident to its formation, its execution of the Merger Agreement and its participation in the preparation of this Proxy Statement/Prospectus. Vista has no material assets or liabilities, other than its rights and obligations under the Merger Agreement, the Midland Exchange Agreement and the Vista Exchange Agreement, and has not generated any material revenues or expenses. The Merger will create a newly formed independent oil and gas company by combining the oil and gas reserves, operations and businesses of the Vista Partnership and Midland. Vista's growth strategy involves a coordinated balance of acquisitions, exploitation and exploration. Drilling and production operations will be located in Texas and New Mexico. 20 24 THE MIDLAND MEETING DATE, TIME AND PLACE The Midland Meeting will be held on October 28, 1998 at 10:00 a.m., Midland, Texas time, at The Midland Room, Fasken Center, Tower II, 2nd Floor, 550 West Texas Avenue, Midland, Texas. PURPOSE OF MIDLAND MEETING The Midland Meeting of the stockholders of Midland has been called by the Midland Board. The stockholders of Midland are being asked to consider and vote upon the proposal to approve and adopt the Merger Agreement, which is described in more detail elsewhere in this Proxy Statement/Prospectus. See "Certain Terms of the Merger Agreement, the Vista Exchange Agreement and the Midland Exchange Agreement." RECORD DATE; HOLDERS ENTITLED TO VOTE The Midland Board has established September 23, 1998 ("Midland Record Date") as the date to determine those record holders of Midland Common Stock entitled to notice of and to vote at the Midland Meeting and any adjournments or postponements thereof. QUORUM; VOTE REQUIRED The presence, in person or by proxy, of the holders of a majority of the shares entitled to vote is necessary to constitute a quorum at the Midland Meeting. The approval and adoption of the Merger Agreement to be voted on at the Midland Meeting requires the affirmative vote of the holders of at least two-thirds (66 2/3%) of the outstanding shares of Midland Common Stock. Holders of Midland Common Stock will not be entitled to dissenters' rights in connection with the Merger. The persons voting proxies submitted to the Midland Meeting by Midland stockholders will not use discretionary authority granted from proxies voting against the Merger to adjourn the Midland Meeting in order to solicit additional votes. SOLICITATION OF PROXIES Solicitation of proxies for use at the Midland Meeting may be made in person or by mail, telephone, telecopy or telegram. Midland will bear the cost of solicitation of proxies from its stockholders and Midland and Vista will share equally the Registration Statement filing fees and the cost of printing this Proxy Statement/Prospectus. In addition to solicitation by mail, the directors, officers and regular employees of Midland and its subsidiaries may solicit proxies from stockholders of Midland by telephone, telecopy or telegram, or in person. Midland has requested banking institutions, brokerage firms, custodians, trustees, nominees and fiduciaries to forward solicitation materials to the beneficial owners of Midland Common Stock held of record by such entities, and Midland will, upon the request of such record holders, reimburse reasonable forwarding expenses. In addition, Midland and Vista have engaged American Stock Transfer & Trust Company to assist in the solicitation of proxies. Vista anticipates that it will incur total fees of approximately $12,500, plus reimbursement of certain out-of-pocket expenses for this service. 21 25 MARKET PRICE DATA There is no established trading market for the securities of the Vista Partnership or the General Partner. Application will be made for the shares of Vista Common Stock to be listed on the ASE. Midland Common Stock is traded on the ASE under the symbol "MLD." Midland Common Stock was originally authorized for trading on NASDAQ Small-Cap Issues in May 1991 and, in August 1997, Midland listed with the ASE. The following table sets forth the high and low sales prices of Midland Common Stock for the periods indicated. HIGH LOW ---- --- 1996 Quarter ended March 31.................................... 3 7/8 2 5/8 Quarter ended June 30..................................... 4 1/4 3 1/8 Quarter ended September 30................................ 3 3/4 2 7/8 Quarter ended December 31................................. 3 1/4 1 15/16 1997 Quarter ended March 31.................................... 6 1/2 2 5/8 Quarter ended June 30..................................... 7 3/4 4 1/2 Quarter ended September 30................................ 5 1/8 3 1/8 Quarter ended December 31................................. 4 1 7/8 1998 Quarter ended March 31.................................... 4 1/8 2 1/8 Quarter ended June 30..................................... 4 1 7/8 Quarter ending September 30 (through September 11)........ 2 3/4 1 1/2 On May 22, 1998, the last full trading day prior to the public announcements by the Vista Partnership and Midland of the proposed Merger, the last reported sales price on the ASE of the Midland Common Stock was $3 5/8 and the high and low sales prices were $3 3/4 and $3 1/2, respectively. As of the last trading date immediately before the date of this Proxy Statement/Prospectus, the last reported sales price on the ASE of the Midland Common Stock was $3 9/16 and the high and low sales prices were $3 3/4 and $3 9/16, respectively; On September 11, 1998, there were 7,271,251 Partnership Interests of the Vista Partnership held of record by 25 securityholders and there were 4,467,699 shares of Midland Common Stock outstanding held of record by 1,353 stockholders. DIVIDEND POLICIES The Vista Partnership has not paid distributions to its partners and Midland has not paid dividends on its capital stock. It is Vista's intention to retain earnings to fund future growth and, therefore, Vista will not pay dividends. 22 26 THE MERGER GENERAL The Vista Partnership, Midland, Vista and Merger Sub have entered into the Merger Agreement which provides that, subject to the satisfaction of the conditions thereof (see "Certain Terms of the Merger Agreement, the Vista Exchange Agreement and the Midland Exchange Agreement -- Conditions to the Merger"), the Merger will be effected. THE DESCRIPTION OF THE MERGER AGREEMENT CONTAINED IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER AGREEMENT, A COPY OF WHICH IS INCLUDED AS APPENDIX A TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED IN ITS ENTIRETY HEREIN BY REFERENCE. THE MERGER The final structure of the Merger, the Midland Exchange and the Vista Exchange, as respectively set out in the Merger Agreement, the Midland Exchange Agreement and the Vista Exchange Agreement, respectively, provide that (i) Vista will be formed as a new Delaware corporation; (ii) holders of Partnership Interests and GP Common Stock will exchange all of their interests in the Vista Partnership and the General Partner for shares of outstanding Vista Common Stock (together with Vista Warrants to purchase 8,564,146 shares of Vista Common Stock at $4.00 per share and having terms substantially similar to the Midland Warrants, including their expiration at the same time as the Midland Warrants, with such transaction being tax free under Section 351 of the Code); (iii) Merger Sub, a newly formed, wholly owned subsidiary of Vista, will be merged with and into Midland with Midland being the Surviving Subsidiary, upon which Midland stockholders would receive shares of Vista Common Stock equal to 27.5% of the outstanding shares of Vista Common Stock in exchange for their stock in Midland, with such transaction being tax free under Sections 351 and 368 of the Code; (iv) after such transactions the former holders of Partnership Interests and GP Common Stock and former Midland stockholders will own all of the issued and outstanding Vista Common Stock in accordance with their 72.5% and 27.5% combination ratios; (iv) all currently existing and outstanding Midland Warrants to purchase 2,253,094 shares of Midland Common Stock at $4.00 per share, all of which expire in November 2002 will become exercisable for Vista Common Stock on a one-to-one basis after the closing of the Merger; (v) all Midland Stock Options (other than the Midland Exchange Stock Options) to acquire 268,000 shares of Midland Common Stock at various exercise prices will expire within 120 days after the closing of the Merger unless otherwise exercised; (vi) all currently existing Midland Exchange Stock Options to acquire 1,372,931 shares of Midland Common Stock at an exercise price of $3.00 per share will be exchanged by their holders for Vista Warrants to purchase 995,375 shares of Vista Common Stock at $4.00 per share; and (vii) the currently existing Midland Common Stock Warrants to purchase 270,000 shares of Midland Common Stock at various exercise prices and containing various termination dates which were issued to various financial advisers and brokers over the last few years by Midland in return for various services will (unless otherwise agreed to by the holders of the Midland Common Stock Warrants prior to closing of the Merger) become exercisable for Vista Common Stock on a one-to-one basis after the closing of the Merger; provided, however, the Vista owners will receive additional shares of Vista Common Stock in order to maintain their 72.5% sharing ratio based on the number of Midland Common Stock Warrants whose exercise price is equal to or less than the ASE trading price of the Midland Exercisable Warrants. THE VISTA EXCHANGE During May and June of 1998, and as contemplated by the Merger Agreement, the holders of all of the outstanding GP Common Stock and the holders of all of the outstanding Partnership Interests entered into the Vista Exchange Agreement. Pursuant to the terms of such agreement, at the Effective Time, without any action on the part of any holder thereof, (a) each share of GP Common Stock that is issued and outstanding prior to the Effective Time shall be exchanged for (i) a number of shares of Vista Common Stock equal to the Vista GP Conversion Stock Number (being 1.60089817) and (ii) a Vista Warrant that is exercisable for a number of shares of Vista Common Stock equal to the Vista GP Conversion Warrant Number (being 1.16511028) and (b) each Partnership Interest that is issued and outstanding prior to the Effective Time shall be exchanged for (i) a number of shares of Vista Common Stock equal to the Vista LP Conversion Stock 23 27 Number (being 117,674.06) and (ii) a Vista Warrant that is exercisable for a number of shares of Vista Common Stock Equal to the Vista LP Conversion Warrant Number (being 85,641.46). As provided in the Vista Exchange Agreement, any fractional Partnership Interest shall be likewise exchanged on a pro rata basis. Pursuant to the terms of the Vista Exchange Agreement, the holders of GP Common Stock and Partnership Interests will receive 11,778,479 shares of Vista Common Stock, representing 72.5% of such shares outstanding at the Effective Time, and warrants exercisable for 8,564,146 shares of Vista Common Stock, representing 34.5% of such shares outstanding at the Effective Time (assuming for purposes of this calculation exercise of all such warrants as of such time). The warrants will be issued to prevent the dilutive effect of existing Midland Warrants to holders of GP Common Stock and Partnership Interests. THE MIDLAND EXCHANGE During May and June of 1998, and as contemplated by the Merger Agreement, Sam R. Brock, a director of Midland, Darrell M. Dillard, a director of Midland, Robert R. Donnelly, president and a director of Midland, Wayne M. Whitaker, a director of Midland, John Q. Adams, an advisory director of Midland and Marilyn D. Wade, corporate secretary of Midland, who hold all issued and outstanding options to acquire shares of Midland Common Stock ("Midland Exchange Stock Options") granted pursuant to the Midland Resources, Inc. 1997 Board of Directors' Stock Incentive Plan (the "Midland Directors Plan"), and 137,931 options granted pursuant to the 1996 Midland Resources, Inc. Long-Term Incentive Plan (the "Midland Incentive Plan") entered into separate exchange agreements with Vista (collectively, the Midland Exchange Agreement"). Pursuant to the terms of such agreement, at the Effective Time, without any action on the part of any holder thereof, each Midland Exchange Stock Option will be exchanged for a Vista Warrant that is exercisable for that whole number of shares of Vista Common Stock (to the nearest whole share) equal to the product of (x) .725 times (y) the number of shares of Vista Common Stock into which the shares of Midland Common Stock subject to such Midland Exchange Stock Option would be converted pursuant to the Merger. Pursuant to the Midland Exchange Agreement, no payment shall be made for fractional interests. Pursuant to the terms of the Midland Exchange Agreement, each Midland Exchange Stock Option subject thereto shall be terminated immediately following its exchange for a Vista Warrant. Pursuant to the terms of the Midland Exchange Agreement, the holders of Midland Exchange Stock Options will receive warrants exercisable for 995,375 shares of Vista Common Stock, representing 5.8% of such shares outstanding at the Effective Time (assuming for purposes of this calculation exercise of all such warrants as of such time).

BACKGROUND OF THE MERGER In November 1996, the Midland Board established certain operational objectives and goals for management to achieve. Thereafter, during the first seven months of 1997, Midland conducted drilling on four of its exploration projects and achieved four commercial wells. The use of Midland's resources to drill these four exploratory wells, coupled with the results management had achieved in meeting the operational objectives and goals, resulted in the Midland Board determining that the company should consider various strategic alternatives including the issuance of equity or debt, the sale of assets, and the merger with or acquisition of another company. Thereafter, on August 8, 1997, Midland engaged First Union Capital Markets Corp. ("First Union"), an entity affiliated with Midland's senior lender, to assist and advise in considering these alternatives. Following the engagement of First Union, the Midland Board determined that a transaction with another company would be the most likely method to permit the company to achieve its financial and operational objectives and goals and increase value for its stockholders. Beginning in September 1997, First Union sent information packages to approximately 50 companies, seeking both a cash transaction as well as transactions involving only the exchange of equity securities. As a result of these activities, no formal offer to purchase Midland's assets in a cash transaction was received. Although various companies expressed some level of interest in pursuing discussions with Midland, only two companies expressed significant interest in a transaction involving only the exchange of equity securities. However after due diligence and limited negotiations, no formal offers were received from either of these companies. Given the significant level of time devoted by Midland's management to these negotiations and in assisting First Union, coupled with the lack of apparent success, the Midland Board determined in December 1997 to terminate the engagement of First Union and complete any ongoing discussions with potential transaction candidates before developing and pursuing other strategies intended to meet its original objectives. Under the agreement by which Midland engaged First Union, First Union was to receive up to 2% of the gross consideration received by Midland or its stockholders in an acquisition transaction. Midland intends to dispute whether First Union has complied with such engagement agreement so as to entitle it to receive such compensation. To the extent any amount is determined to be owed by Midland to First Union under such agreement, such amount will be paid by Vista. On November 13, 1997, Mr. C. Randall Hill, the Chairman and Chief Executive Officer of the General Partner, contacted Mr. Bill Haskins of First Union, and expressed the Vista Partnership's interest in learning more about Midland and its plans for the future, including whether Midland would be interested in pursuing a potential business combination with the Vista Partnership. Mr. Hill followed up the telephone conversation with a letter dated November 13, 1997 addressed to Mr. Haskins in which Mr. Hill requested information about Midland and provided preliminary information to First Union about the Vista Partnership. 25 29 On or about November 17, 1997, the Vista Partnership received a proposed confidentiality agreement concerning and covering non-public Midland data and information to be supplied by Midland through First Union. The confidentiality agreement was executed by the Vista Partnership and returned to First Union on November 18, 1997. Mr. Hill also requested that First Union forward a copy of the Midland Information Memorandum (herein so called) for the Vista Partnership's review. On December 2, 1997, Mr. Haskins informed Mr. Hill that Midland was not interested in pursuing a potential business combination with the Vista Partnership. Mr. Hill then sent a letter dated December 2, 1997, and addressed to each member of the Midland Board. Such letter expressed the Vista Partnership's disappointment in Midland's decision to not pursue discussions with the Vista Partnership about a possible business combination without either party having been provided any significant information about the other and without the Vista Partnership being permitted to address the Midland Board about the Vista Partnership's business and properties as well as why the Vista Partnership believed a business combination with Midland might be beneficial to each company's stockholders and partners. Later in the day on December 2, 1997, Mr. Haskins called Mr. Hill and informed him that the Midland Board was in fact interested in learning more about the Vista Partnership and was interested in discussing a possible business combination. The next day the Vista Partnership received a copy of the Midland Information Memorandum along with other previously requested due diligence information. From December 2, 1997 through December 17, 1997, Darrell Dillard, one of the members of the Midland Board, contacted Mr. Hill concerning the status of the Vista Partnership's review of Midland and so that Mr. Dillard could learn more information about the Vista Partnership. On various occasions during this period, Mr. Dillard and four of the five members of the Midland Board met in the General Partner's offices in Midland, Texas with Mr. Hill, Mr. Steven D. Gray, the General Partner's President, and Mr. R. Cory Richards, the General Partner's Vice President and Exploration Manager. The primary purpose of each of these meetings was for each of the members of the Midland Board to learn more about the Vista Partnership, its business, properties, operations and management team. At these meetings, the idea of combining the two companies was generally discussed, along with strategies for growth, attitudes toward leverage, management philosophies and other pertinent matters. On December 18, 1997, Mr. Hill faxed a preliminary proposal for a business combination to First Union for further delivery to the Midland Board. Such proposal was included in a Vista Presentation (herein so called) dated December 19, 1997. Such proposal was for a tax free, stock-for-stock merger of the two companies pursuant to which the stockholders of Midland would own 25% of the combined company and the owners of the Vista Partnership would own 75% of the combined company (the "Initial Vista Proposal"). Late in the afternoon on December 18, 1997, Mr. Hill received a telephone call from Mr. Haskins of First Union informing Mr. Hill that First Union's relationship as financial advisor to Midland had been terminated and suggested that further contact between the Vista Partnership and Midland should not be made through First Union. By letter dated December 18, 1997, Mr. Warley informed Mr. Hill that he believed the Initial Vista Proposal was inadequate. On December 22, 1997, the complete Vista Presentation, together with the Initial Vista Proposal, was sent directly to each board member of Midland by overnight mail. On December 29, 1997, and again on December 30, 1997, Mr. Hill and Mr. Gray met with Mr. Dillard concerning the Vista Partnership's continued interest in pursuing a potential business combination along the lines of the Initial Vista Proposal. Throughout the first week of January 1998, various telephone calls and meetings resulted in Mr. Hill and Mr. Dillard agreeing that, subject to the approval of both companies' respective boards, the Vista Partnership and Midland would enter into a letter agreement pursuant to which the Vista Partnership would have the exclusive right to negotiate a definitive merger agreement with Midland through February 19, 1998. The General Partner's board of directors was informed of the potential business combination and the Initial Vista Proposal through a series of phone calls with Mr. Ken Hersh, Mr. David Albin and Mr. John Foster on or about January 7, 1998. All General Partner board members unanimously agreed to proceed with execution of the proposed letter agreement. Such letter agreement was entered into as of January 14, 1998 (as amended from time to time, the "Letter Agreement"), and provided for, among other things, a non-binding expression of interest in pursuing a tax free, stock-for-stock merger between the two companies pursuant to which the stockholders of Midland 26 30 would own 26% of the combined company and the owners of the Vista Partnership would own 74% of the combined company (the "Second Vista Proposal"). Pursuant to the terms of the Letter Agreement, the Second Vista Proposal was a non-binding expression of mutual intent, subject to the fulfillment of a number of conditions including, without limitation, the negotiation and execution of a definitive merger agreement and related documentation, the requisite approval of the stockholders of Midland, and the preparation and delivery of acceptable final, independent reserve reports by Williamson Petroleum Consultants ("Williamson") on each company's reserves (individually, the "Vista Williamson Report" or the "Midland Williamson Report," as the case may be, and collectively, the "Williamson Reports"). The Letter Agreement also provided that the Vista Partnership would have the exclusive right to negotiate a definitive merger agreement with Midland until February 19, 1998, on the assumption that the Vista Williamson Report and the Midland Williamson Report would be completed by February 16, 1998. On January 20, 1997, Mr. Warley met with Messrs. Hill and Gray in the General Partner's offices in Midland. At such meeting, Mr. Hill and Mr. Warley discussed a timetable for due diligence matters, timing of the Williamson Reports and other related issues. Mr. Hill and Mr. Gray also discussed various aspects of the Vista Partnership so that Mr. Warley could learn more about the Vista Partnership, its business, properties, operations, and management team. Mr. Hill also discussed the Vista Partnership's history, its strategies for growth, management philosophies and other pertinent matters. From and after January 20, 1998, through February 10, 1998, the Vista Partnership and Midland continued due diligence reviews of each company's business, operations, prospects and financial position. Also, both companies continued to work with Williamson on preparation of the Williamson Reports. On February 12, 1998, the Vista Partnership and Midland entered into an amendment of the Letter Agreement extending its terms through March 2, 1998, in order to give Williamson sufficient time to complete the Williamson Reports. On February 25, 1998, the Vista Partnership and Midland entered into Amendment No. 2 to the Letter Agreement to extend its term through March 20, 1998, in order to give Williamson more time to complete the Williamson Reports. Williamson completed the Vista Report on or about March 5, 1998, and such report was forwarded to Midland for review and additional due diligence review of the reserves. On March 13, 1998, the Vista Partnership and Midland entered into Amendment No. 3 to the Letter Agreement extending its terms through March 31, 1998, in order to give Williamson more time to finish the Midland Report. On March 30, 1998, the Vista Partnership and Midland entered into Amendment No. 4 to the Letter Agreement extending its terms through April 17, 1998, in order to give Williamson more time to finish the Midland Report. Williamson completed the Midland Report on or about April 5, 1998, and such report was forwarded to the Vista Partnership for review and additional due diligence review of the Vista Partnership's reserves. On April 8, 1998, representatives of Midland, being Mr. Wayne Whitaker, Mr. Dillard, and Mr. Robert R. Donnelly met at the offices of the Vista Partnership with Messrs. Hill, Gray and Richards to negotiate the main terms of a business combination. In the afternoon, the Midland negotiating group convened in Mr. Dillard's office in Midland, Texas to deliberate and continue to negotiate by telephone with the Vista Partnership negotiating group. Later that afternoon, the boards of the two companies unanimously approved the main terms of the transaction (which remained subject to the satisfaction of a number of conditions including, without limitation, definitive documentation, the delivery of a fairness opinion and the requisite approval of Midland's stockholders). A press release announcing the unanimous approval by the Midland Board of the main terms of the Merger was released on April 9, 1998. The main terms included a tax free, stock-for-stock merger between the two companies pursuant to which the stockholders of Midland would own 27.5% of the combined company and the owners of the Vista Partnership would own 72.5% of the combined company (the "Final Main Terms"). It was also announced that the management team of the Vista Partnership would become the management team of the newly combined company and the headquarters of the newly combined company would be located in Midland, Texas. From and after April 10, 1998, the parties began drafting and negotiating definitive merger documentation and Midland engaged Dain Rauscher Incorporated ("Dain Rauscher") for the purpose of rendering a fairness opinion. On April 13, 1998, the Vista Partnership and Midland entered into Amendment No. 5 to the Letter Agreement extending its terms through April 29, 1998, in order to give both parties sufficient time to negotiate 27 31 and draft definitive merger documentation and for Dain Rauscher to complete and deliver a fairness opinion. From April 13 through April 28, 1998, representatives of the Vista Partnership and Midland, including their legal counsel, held meetings to further conduct due diligence reviews of the other party and to negotiate and draft a definitive merger agreement along with all ancillary exhibits and disclosure schedules to the definitive merger agreement. Also during this period, both Midland personnel and the Vista Partnership personnel had numerous discussions with representatives of Dain Rauscher concerning the structure of the Merger and the business, operations, prospects, properties and financial condition of both the Vista Partnership and Midland. On April 28, 1998, the Vista Partnership and Midland entered into Amendment No. 6 to the Letter Agreement extending its terms through May 8, 1998, in order to give both parties sufficient time to negotiate and draft definitive merger documentation and for Dain Rauscher to complete and deliver a fairness opinion. From April 28 to May 8, 1998, the parties continued to negotiate and revise drafts of definitive merger documentation and to provide Dain Rauscher with additional information about the two companies in order for Dain Rauscher to be able to complete and deliver a fairness opinion. On May 8, 1998, and again on May 18, 1998, the parties entered into Amendments Nos. 7 and 8, respectively, to extend the terms of the Letter Agreement through May 18 and May 27, 1998, respectively, in order to give the parties sufficient time to finalize all definitive merger documentation. On May 22, 1998, the parties finalized all definitive merger documentation. The Midland Board held a special meeting in Fort Worth, Texas and unanimously approved the execution and delivery of an Agreement and Plan of Merger dated May 22, 1998 (as amended from time to time, the "Merger Agreement"). On the evening of May 22, 1998, Midland and the Vista Partnership, after final negotiations, executed the Merger Agreement. All members of the Midland Board being Messrs. Warley, Whitaker, Dillard, Donnelly, Sam Brock and advisory member John Adams executed voting agreements pursuant to which they agreed, among other things, to vote in favor of the approval of the Merger Agreement at the Midland Special Meeting. On May 26, 1998 the Vista Partnership and Midland publicly announced the execution and delivery of the Merger Agreement. RECOMMENDATION OF MIDLAND'S BOARD OF DIRECTORS; MIDLAND'S REASONS FOR THE MERGER THE MIDLAND BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF MIDLAND COMMON STOCK VOTE IN FAVOR OF THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. The Midland Board believes that the terms of the Merger Agreement and the transactions contemplated thereby are fair to and in the best interests of Midland and its stockholders. Accordingly, the Midland Board has approved the Merger Agreement and recommends approval and adoption thereof by the stockholders of Midland. In view of the wide variety of factors considered in connection with its evaluation of the Merger, the Midland Board did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weight to the specific factors considered in reaching its determination to recommend approval of the Merger and the Merger Agreement. In reaching its determination, the Midland Board consulted with Midland management and considered a number of strategic, financial and other factors, including without limitation those described below. Strategic Considerations. The Midland Board assessed Midland's properties that it currently operates, the developmental potential of properties from its exploration activities and its financial position in light of the capital needed to fully develop its assets. As a part of this assessment, the Midland Board considered strategic alternatives that would enhance stockholder value, including whether to remain a separate company, sell additional equity or debt to fund future development of its assets, or make additional property acquisitions or divest a significant amount of assets and use those funds to develop its assets or reduce debt. In this respect, the Midland Board concluded, following extensive discussions with Midland's management and among the directors, that the transactions contemplated by the Merger Agreement provided the best means for holders of Midland Common Stock to maximize the value of their holdings. 28 32 Property Characteristics. The Midland Board considered many aspects of the Vista Partnership properties to be attractive in the context of a merger. Specifically, the Midland Board considered that (i) the Vista Partnership operated a significant number of its properties, which was consistent with the Midland Board's belief that controlling property operations is important, (ii) that a significant number of both companies' properties were close geographically, thereby allowing operational efficiencies, and (iii) the long life nature of the properties, thereby providing for relatively predictable operating conditions. The Midland Board also considered that Midland's higher gas production would balance the greater oil production of the Vista Partnership and that the amount of development potential of Midland's properties would provide the combined company with future drilling opportunities. Financial. The Midland Board considered the historical financial performance of both companies as well as a financial analysis of the impact of the Merger on the balance sheet and cash flow of the combined company. Based upon historical operating costs achieved by the Vista Partnership and coupled with certain anticipated operating efficiencies of the combined company, the Midland Board believes that the combined company will achieve a greater return on Midland's currents assets than it has historically achieved. The Midland Board believes that the combined company will have improved credit ratios from those it currently has, which it believes will allow the combined company to have a lower cost of capital and a better ability to withstand a downturn in oil and gas prices and the business cycle. Efficiencies. The Midland Board viewed favorably the opportunities for operating efficiencies that it believes can be achieved from the Merger, particularly from the integration of office facilities, technical personnel, support functions and consolidation of certain field operations. Management. The Midland Board considered the management strengths of the Vista Partnership and believes C. Randall Hill, Steven D. Gray and R. Cory Richards, the current Chairman and Chief Executive Officer, President and Vice President -- Exploration, respectively, of the General Partner of the Vista Partnership, are highly trained and qualified personnel who have demonstrated an ability to profitably locate, purchase and produce oil and gas properties. Access to Capital. The Midland Board considered that the combined company should have a greater ability to access the capital markets and otherwise increase its financial flexibility, which would allow capitalizing on acquisition and development opportunities. Exchange Ratio/Market Price. The Midland Board considered the Midland Conversion Number and recent trading prices for Midland Common Stock. The Midland Board analyzed the ownership structure of the combined company and had discussions with Midland's management and among the directors, and determined that the Midland Conversion Number was fair and in the best interests of the Midland stockholders. Fairness Opinion. The Midland Board considered analyses provided by Dain Rauscher Wessels, a division of Dain Rauscher Incorporated, which included Midland Common Stock trading prices and volumes, financial, operational and market information and ratios of comparable companies, comparable merger and acquisition transactions, cash flow analyses and the restructure of stock options. The Midland Board considered the presentation made by representatives of Dain Rauscher Wessels at the meeting of the Midland Board on May 21, 1998 regarding its preliminary valuation and financial analysis of the Merger, that was confirmed by its final valuation and financial analysis presented at a meeting of the Midland Board on June 25, 1998, and in writing with delivery of its written fairness opinion on June 30, 1998, that the Merger was fair from a financial point of view to the holders of Midland Common Stock. See "-- Opinion of Midland's Financial Advisor." The Midland Board believes that the Merger offers the opportunity to create a combined company that will have greater competitive strengths, business opportunities, financial resources and flexibility than Midland could achieve alone. OPINION OF MIDLAND'S FINANCIAL ADVISOR On June 30, 1998, Dain Rauscher Wessels, a division of Dain Rauscher Incorporated ("DRW"), delivered its written opinion to the Midland Board that as of the date of such opinion the Merger is fair from a 29 33 financial point of view to the holders of the currently outstanding Midland Common Stock. THE FULL TEXT OF THE WRITTEN OPINION OF DRW DATED JUNE 30, 1998, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED HERETO AS APPENDIX D-1 AND D-2 TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS OF MIDLAND ARE URGED TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY. DRW HAS CONSENTED TO THE USE OF ITS OPINION IN THIS PROXY STATEMENT/PROSPECTUS. In connection with DRW's review of the Merger, and in arriving at its opinion described below, DRW has reviewed business and financial information relating to Midland and the Vista Partnership. DRW has, among other things: (i) reviewed the Merger Agreement; (ii) reviewed the Annual Reports on Form 10-KSB for the years ended December 31, 1995, 1996 and 1997 and the Quarterly Reports on Form 10-QSB and related unaudited financial information for certain interim periods, including the three months ended March 31, 1998, of Midland; (iii) reviewed the Proxy Statement filed on Schedule 14A dated May 29, 1997 of Midland; (iv) reviewed the audited financial statements for the years ended December 31, 1997 and 1996 and the period from inception (September 21, 1995) to December 31, 1995, audited by Arthur Andersen LLP, independent public accountants, and the unaudited financial statements for the three months ended March 31, 1998 of the Vista Partnership; (v) reviewed Midland's proved oil and gas reserves and the standardized measure of discounted future net cash flows relating to proved oil and gas reserves as of January 1, 1998, estimated by Williamson Petroleum Consultants, Inc., independent petroleum engineers; (vi) reviewed the Vista Partnership's proved oil and gas reserves and the standardized measure of discounted future net cash flows relating to proved oil and gas reserves as of January 1, 1998, estimated by Williamson Petroleum Consultants, Inc., independent petroleum engineers; (vii) met with certain members of Midland's and the Vista Partnership's senior management to discuss their respective operations, historical financial statements and future prospects and their views of the business, operational and strategic benefits, potential synergies and other implications of the Merger; (viii) reviewed certain operating and financial information of Midland and the Vista Partnership, including projections and projected cost savings and operating synergies, provided to us by Midland's and the Vista Partnership's management relating to their respective businesses and prospects; (ix) reviewed the projected consolidated pro forma financial statements for the combined companies for the years ending December 31, 1998 and 1999 as prepared by Midland's and the Vista Partnership's management; (x) reviewed historical market prices and trading volumes for Midland Common Stock; (xi) reviewed publicly available financial data and stock market performance data of publicly held companies that we deemed generally comparable to Midland and the Vista Partnership; and (xii) reviewed the financial terms of certain business combinations of comparable exploration and production companies. In addition, DRW has considered such other information and has conducted such other analyses and investigations as it deemed appropriate under the circumstances. DRW relied upon the accuracy and completeness of all of the financial and other information reviewed by it and has assumed such accuracy for purposes of its opinion. DRW has relied solely upon the reserve reports and internal estimates prepared by the independent petroleum engineers and managements of Midland and the Vista Partnership and reviewed by Midland. DRW has assumed with Midland's consent that such information and the financial forecasts provided to DRW and discussed with DRW with respect to Midland and the Vista Partnership after giving effect to the Merger have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Midland and that such forecasts will be realized in the amounts and at the times contemplated thereby. DRW's opinion was based upon economic and market conditions existing on the date of such opinion. The following is a summary of certain of the financial analyses used by DRW in its presentations to the Midland Board on May 21, 1998 and June 25, 1998 and in connection with providing its written opinion to the Midland Board on June 30, 1998. Historical Trading Analysis. DRW reviewed the daily historical closing prices and volumes for shares of Midland Common Stock during the period from January 2, 1998 to June 12, 1998. Comparable Company Analysis. DRW reviewed and compared certain financial, operating and market information relating to Midland to corresponding financial information, ratios and public multiples for six 30 34 small capitalization, acquisition and exploitation focused exploration and production companies: Abraxas Petroleum Corporation; Comstock Resources, Inc.; Costilla Energy, Inc.; Magnum Hunter Resources, Inc.; Southern Mineral Corporation and Titan Exploration, Inc. (the "Selected Companies"). The Selected Companies were chosen because they are publicly traded companies with operations that for purposes of analysis can be considered similar to Midland. The multiples and ratios for the Selected Companies were based on DRW estimates and latest public information. DRW considered certain publicly available information for the Selected Companies, including, but not limited to, (i) stock price as a multiple of discretionary cash flow ("DCF") (net income plus depreciation, depletion and amortization, deferred taxes, exploration expenses and other non-cash items before changes in working capital) as estimated for the 1998 (the "1998E P/DCF Multiple") and 1999 (the "1999E P/CF Multiple") calendar years; (ii) market value of capitalization ("MVC") (market value of equity plus book value of total debt and liquidation value of preferred stock, less excess cash and equivalents) as a ratio of 1997 pretax PV-10% Value ("1997 PV-10") (estimated value of total proved reserves at December 31, 1997 based on oil and gas prices at December 31, 1997 and applying a 10% discount rate, calculated based on guidelines promulgated by the Commission) (the "MVC/1997 PV-10 Ratio); and (iii) MVC as a multiple of earnings before interest, taxes, depreciation, depletion and amortization and exploration expenses ("EBITDX") as estimated for the 1998 (the "1998E MVC/EBITDX Multiple") and 1999 (the "1999E MVC/EBITDX Multiple") calendar years. DRW's analyses indicated (i) 1998E P/DCF Multiples for the Selected Companies ranged from 2.8x to 15.0x with a mean of 6.8x, compared with 16.5x for Midland; (ii) 1999E P/DCF Multiples for the Selected Companies ranged from 2.2x to 7.7x with a mean of 4.3x, compared with 13.3x for Midland; (iii) MVC/1997 PV-10 Ratios for the Selected Companies ranged from 92.8% to 157.4% with a mean of 125.3%, compared with 126.9% for Midland; (iv) 1998E MVC/EBITDX Multiples for the Selected Companies ranged from 4.9x to 13.2x with a mean of 8.3x, compared with 15.1x for Midland; and (v) 1999E MVC/EBITDX Multiples for the Selected Companies ranged from 4.4x to 9.1x with a mean of 6.2x, compared with 13.5x for Midland. No company utilized in the comparable company analysis is identical to Midland. Accordingly, an analysis of the foregoing is not purely mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the comparable companies and other factors that could affect the public trading value of the comparable companies or company to which they are being compared. Comparable Merger & Acquisition Transaction Analysis. DRW considered certain publicly announced completed business combinations in the oil and gas sector for which terms were publicly available, including the following 21 transactions announced between March 1994 and May 1998: Lomak Petroleum, Inc.'s acquisition of Domain Energy Corporation; Meridian Resource Corp.'s acquisition of Shell Oil Co.'s south Louisiana properties; Ocean Energy, Inc.'s acquisition of United Meridian Corporation; Texoil, Inc.'s acquisition of Cliffwood Oil & Gas Corp.; Chesapeake Energy Corporation's acquisition of Hugoton Energy Corp.; Titan Exploration, Inc.'s acquisition of Carrollton Resources, LLC; Belco Oil & Gas Corp.'s acquisition of Coda Energy, Inc.; Chesapeake Energy Corporation's acquisition of DLB Oil & Gas, Inc.; Southern Mineral Corporation's acquisition of Amerac Energy Corporation; Titan Exploration, Inc.'s acquisition of Offshore Energy Development Corporation; Meridian Resource Corp.'s acquisition of Cairn Energy USA, Inc.; Louis Dreyfus Natural Gas Corp.'s acquisition of American Exploration Company; Forcenergy Inc.'s acquisition of Convest Energy Corporation; Forcenergy Inc.'s acquisition of Edisto Resources Corporation; Monterey Resources, Inc.'s acquisition of McFarland Energy, Inc.; Columbia Natural Resources, Inc.'s acquisition of Alamco, Inc.; Forcenergy Inc.'s acquisition of Great Western Resources, Inc.; Texas Pacific Group, Inc.'s acquisition of Belden & Blake Corporation; HS Resources, Inc.'s acquisition of Tide West Oil Company; Key Production Company, Inc.'s acquisition of Brock Exploration Corporation and Alexander Energy Corporation's acquisition of American Natural Energy Corporation (the "Selected Transactions"). For purposes of this analysis, DRW assumed Midland was acquiring the Vista Partnership in a stock transaction (the "Merger Analysis"). DRW considered certain publicly available information for the Selected 31 35 Transactions, including, but not limited to, (i) transaction value to target company total proved reserves ("Transaction Value/Proved Reserves") and (ii) transaction value to target company PV-10% Value ("Transaction Value/PV-10"). DRW calculated multiples based on the consideration attributable to oil and gas reserves for each of the Selected Transactions to, among other things, such acquired companies' respective proved reserves. DRW's analyses indicated (i) Transaction Value/Proved Reserves for the Selected Transactions ranged from $2.55 to $14.37 per BOE with a mean of $7.09 per BOE, compared with $5.56 per BOE for the Merger Analysis and (ii) Transaction Value/PV-10 for the Selected Transactions ranged from 0.6x to 2.2x with a mean of 1.1x, compared with 1.1x for the Merger Analysis. No transaction utilized in the comparable merger and acquisition transaction analysis is identical to the Merger Analysis. In evaluating the Selected Transactions, DRW made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Midland, such as the impact of competition on the business of Midland, the Vista Partnership and the industry generally, industry growth and the absence of any material change in the financial condition and prospects of Midland or the Vista Partnership or the industry or in the financial markets in general. Mathematical analysis is not in itself a meaningful method of using comparable transaction data. Contribution Analysis. DRW reviewed certain estimated future operating and financial information (including, among other things, estimated proved reserves and future net revenue from oil and gas properties) for Midland and the Vista Partnership based on reserve studies as of January 1, 1998, estimated by Williamson Petroleum Consultants, Inc., independent petroleum engineers. Based on the reserve studies, DRW calculated field cash flow ("Field Cash Flow") (total net revenue less ad valorem taxes and lease operating expenses) as estimated for the 1998 ("1998E Field Cash Flow") and 1999 ("1999E Field Cash Flow") calendar years for Midland and the Vista Partnership. This analysis indicated that Midland stockholders, who will receive 27.5% of the equity interest in the combined company, would contribute (i) 35.1% of the 1998E Field Cash Flow of the combined company and (ii) 32.7% of the 1999E Field Cash Flow of the combined company. According to Midland management, Midland does not currently have the capital available to fund future development of its proved undeveloped reserves. DRW calculated Field Cash Flow, excluding the development of proved undeveloped reserves, for the same time periods for Midland. Based on this analysis, Midland stockholders would contribute (i) 29.5% of the 1998E Field Cash Flow of the combined company and (ii) 23.4% of the 1999E Field Cash Flow of the combined company. The preceding contribution analysis was derived from projections of reserves and future net revenue to the evaluated interests based on economic parameters and operating conditions considered to be applicable as of January 1, 1998. A base oil price of $18.00 per barrel and a base gas price of $2.40 per Mcf were provided to Williamson Petroleum Consultants, Inc. by Midland and the Vista Partnership to be used at the effective date. Adjustments to these price assumptions were provided to Williamson Petroleum Consultants, Inc. by Midland and the Vista Partnership based on additional factors on a property-by-property basis. Oil and gas prices have declined since the reserve studies were completed. Average year-to-date through June 12, 1998 WTI Cushing oil price was $14.92 per barrel and average year-to-date through June 12, 1998 Henry Hub gas price was $2.24 per MCF. DRW was informed by Midland management that Midland currently has no hedges in place or contemplated. DRW was informed by management of the Vista Partnership that the Vista Partnership currently employs two costless collar NYMEX WTI oil hedges, one expiring December 31, 1998 for 10,000 barrels per month with put/call prices of $18.00/$19.085 per barrel and one expiring March 31, 1999 for 10,000 barrels per month with put/call prices of $18.50/$19.28 per barrel. The Vista Partnership also has in effect three natural gas hedging contracts through September 1998. One is a costless collar (based on NYMEX Henry Hub Natural Gas) for 80,000 MMBtu per month with put/call prices of $2.20/$2.49 per MMBtu. The other two gas hedges are basis swaps: (i) Houston Ship Channel Basis for 40,000 MMBtu per month at a fixed price of NYMEX Henry Hub minus $0.0275 per MMBtu, and (ii) Permian Basin (El Paso) Basis for 40,000 MMBtu per month at a fixed price of NYMEX Henry Hub minus $0.20 per MMBtu. 32 36 Net Asset Value Analysis. DRW calculated net asset values for Midland and the Vista Partnership based on (i) reserve studies as of January 1, 1998, estimated by Williamson Petroleum Consultants, Inc., independent petroleum engineers, and (ii) unaudited balance sheet information as of March 31, 1998. Utilizing discounted future net revenues generated by Midland and the Vista Partnership proved reserves, DRW applied additional risk adjustments (100% for proved developed producing reserves, 75% for proved developed non-producing reserves and 60% for proved undeveloped reserves) to arrive at risk-adjusted reserve values of $19.3 million for Midland and $39.4 million for the Vista Partnership. By adding other assets and working capital (current assets minus current liabilities, excluding short-term debt) and subtracting long-term debt and estimated off-balance sheet liabilities (estimated by Midland management), DRW calculated risk-adjusted net asset values of $8.9 million for Midland and $22.3 million for the Vista Partnership. Based on this analysis, Midland stockholders, who will receive 27.5% of the equity interest in the combined company, would contribute 28.6% of the net asset value of the combined company. In each of the comparisons of the value to be achieved by the Midland stockholders in the Merger as compared to the mean of the multiples of operating results realized by the stockholders of the Comparable Companies and Merger and Acquisition Transactions, the multiples of operating results achieved by the Midland stockholders were equal or superior to those realized by the Comparable Companies and Merger and Acquisition Transactions. The Contribution Analysis and Net Asset Value Analysis, when viewed in light of the oil and gas environment at the time of the Merger and Midland's current financial and operating situation, indicates that the consideration received was greater or comparable to Midland's contribution. Restructuring of Midland Exchange Stock Options Analysis. In connection with the Merger, Midland intends to restructure the Midland Exchange Stock Options issued under the Midland Directors Plan into a restricted version of the Vista Warrants (being the Midland Exchange). In connection with the analysis of the Midland Exchange, DRW has, among other things: (i) reviewed the stock option agreements governing the Midland Exchange Stock Options; (ii) reviewed the 1997 Board of Directors Stock Incentive Plan; (iii) reviewed the agreement governing the Vista Warrants; (iv) reviewed the registration rights agreement for Midland securityholders; and (v) reviewed publicly available financial data and stock market performance data of Midland Common Stock as well as the publicly traded Midland Warrants. In addition, DRW has considered such other information and has conducted such other analyses and investigations as it deemed appropriate under the circumstances. DRW utilized the Black-Scholes option valuation model to evaluate the Midland Exchange. The Black-Scholes model, utilizing assumptions as of June 12, 1998, returned a value of $0.848 per option for the existing Midland Exchange Stock Options and a value of $1.534 per warrant for the publicly traded Midland Warrants. As of June 12, 1998, the publicly traded Midland Warrants closed at $1.0625 per warrant. 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 Midland Exchange 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, the existing models do not necessarily provide a reliable single measure of fair value of the Vista Warrants. Based on the current price levels of Midland Common Stock, application of the Black-Scholes option pricing model, the restrictions on the Vista Warrants, and an overall business judgment, an exchange ratio of 0.725 Vista Warrants for one Midland Exchange Stock Option is fair as of the date hereof from a financial point of view to the holders of the currently outstanding Midland Common Stock. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. No company or transaction used in the above analyses as a comparison is directly comparable to Midland or the Vista Partnership or the Merger. The analyses were prepared solely for purposes of DRW's providing its opinion to the Midland Board as to the fairness from a financial point of view of the terms of the Merger to the holders of Midland Common Stock and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities may be sold. Analyses based upon forecast of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being 33 37 based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Midland, the Vista Partnership, DRW or any other person assumes responsibility if future results are materially different from those forecast. As described above, DRW's opinion to the Midland Board was one of many factors taken into consideration by the Midland Board in making its determination to approve the Merger Agreement. DRW's opinion was provided to the Midland Board for the information and assistance of the Midland Board in connection with its consideration of the Merger, and such opinion does not constitute a recommendation as to how any holder of Midland Common Stock should vote with respect to the Merger. The foregoing summary does not purport to be a complete description of the analyses performed by DRW or of its presentations to the Midland Board. The preparation of the financial analyses and fairness opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. DRW believes that its analyses (and the summary set forth above) must be considered as a whole, and that selecting portions of such analyses and of the factors considered by DRW, without considering all of the analyses and factors, could create an incomplete view of the processes underlying the analyses conducted by DRW and its opinion. DRW did not attempt to assign specific weights to particular analyses. Any estimates contained in DRW's analyses are not necessarily indicative of actual values, which may be significantly more or less favorable than as set forth herein. Estimates of values of companies do not purport to be appraisals or necessarily to reflect the prices at which companies may actually be sold. DRW, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. DRW in the normal course of its business may trade the securities of Midland for its own account and for the accounts of its customers and, accordingly, may hold a long or short position in such securities at any time. DRW was selected to serve as the Midland Board's financial advisor in connection with the Merger on the basis of DRW's experience with mergers and acquisitions in the energy industry. Midland paid DRW a financial advisory fee of $50,000 upon the execution of its engagement letter and an additional $50,000 at the time DRW delivered the fairness opinion. DRW also was subsequently engaged to evaluate the Midland Exchange of Midland Exchange Stock Options. Midland paid DRW a financial advisory fee of $30,000 upon the execution of its engagement letter and an additional $35,000 at the time DRW delivered the fairness opinion. Midland also agreed to reimburse DRW for its reasonable out-of-pocket expenses and to indemnify DRW and its controlling persons against certain liabilities and expenses relating to or arising out of the consummation of the Merger, including certain liabilities under U.S. Federal securities laws. OTHER AGREEMENTS Voting Agreements. Concurrently with execution of the Merger Agreement, holders of 21.7% of the outstanding shares of Midland Common Stock entered into voting agreements with Vista, pursuant to which such holders have agreed, at any meeting of the holders of Midland Common Stock, to vote such holders' shares in favor of the Merger Agreement and the transactions contemplated thereby. In addition, such holders have agreed to vote against any proposal that might materially adversely affect the Merger. Affiliates Agreements. Rule 145 promulgated under the Securities Act regulates the disposition of securities by "affiliates" of the Vista Partnership and Midland in connection with the Merger. Prior to the Effective Time, Vista will enter into agreements with the affiliates of the Vista Partnership and Midland, pursuant to which such persons will agree that they will not sell any shares of Vista Common Stock unless such transaction is (i) pursuant to an effective registration statement under the Securities Act, (ii) in conformity with the volume and other limitations of Rule 145 or (iii) in reliance upon an exemption from registration that is available under the Securities Act. Midland Resignations and Termination Agreements. Concurrently with execution of the Merger Agreement, Midland obtained written resignations from each of its officers and directors under which such persons have resigned as an officer and/or director of Midland effective as of the Effective Time.

Such termination agreements provide for payment of each employee's annual salary as consideration for such employee's agreement to resign from his or her position with Midland. In addition, the employees agreed to release Midland from any claims relating to the employees' respective employment with Midland and agreed not to disclose to third parties any confidential information relating to Midland's business and operations.

Concurrently with execution of the Merger Agreement, Midland obtained written resignations from each of its officers and directors under which such persons have resigned as an officer and/or director of Midland effective as of the Effective Time. Concurrently with the execution of the Merger Agreement, Midland entered into termination agreements, effective as of the Effective Time, with Howard E. Ehler and Marilyn D. Wade. Such termination agreements provide for payment of each employee's annual salary as consideration for such employee's agreement to resign from his or her position with Midland. In addition, the employees agreed to release Midland from any claims relating to the employees' respective employment with Midland and agreed not to disclose to third parties any confidential information relating to Midland's business and operations. Settlement Agreement. Mr. Warley had a five-year employment contract with Midland that was terminated by the Midland Board on March 27, 1998. As of that date, the employment contract provided for an annual salary of $247,963 with a minimum 5% semi-annual adjustment. Mr. Warley waived such adjustments for 1997. In addition, the contract provided for medical reimbursement of up to $10,000 for non-insurance covered medical expenses, disability payments of one-half the annual salary for 10 years and a covenant not to compete with Midland for six months. The term of the agreement extended for an additional five years each January 1, unless notice was given by either Mr. Warley or Midland. Following termination of Mr. Warley's contract and pending the conclusion of negotiations with respect to the Merger Agreement, Midland and Mr. Warley agreed to Midland paying Mr. Warley one-half of his former monthly salary and providing him the use of a company vehicle. On May 22, 1998, Midland and Mr. Warley executed that certain Warley Settlement Agreement, to be effective March 27, 1998, containing the following principal terms: (i) from March 27, 1998, through either the consummation or termination of the Merger Agreement, Midland shall pay Warley the sum of $11,390 per month; (ii) on the effective date of the Merger, Midland agrees to pay to Warley the sum of $1,300,000 (reduced by a payment of $100,000 made by Midland to Marilyn D.

MATERIAL INCOME TAX CONSEQUENCES The following discussion is a summary of the material United States federal income tax consequences of the Merger and the Vista Exchange and is not intended to be a complete discussion of all potential tax effects that might be relevant to the Merger and the Vista Exchange. Such discussion deals only with persons that are 37 41 citizens or residents of the United States or are entities formed under the laws of the United States (or any state or locality thereof) This summary assumes that the holders of Midland Common Stock, GP Common Stock and Partnership Interests have held such stock or partnership interest as a capital asset. The discussion does not address all aspects of Federal income taxation that may be important to particular stockholders and partnership interest holders and may not be applicable to certain special classes of stockholders and unitholders, including without limitation stockholders and partnership interest holders who are not citizens or residents of the United States, stockholders and partnership interest holders who acquired their stock or partnership interest pursuant to the exercise of employee stock options or otherwise as compensation, stockholders and partnership interest holders that are corporations subject to the alternative minimum tax, insurance companies, tax-exempt organizations, financial institutions, securities dealers, broker-dealers, or foreign partnerships or foreign corporations. Moreover, the state, local, foreign and estate tax consequences of the Merger and the Vista Exchange are not discussed. This summary is based on laws, regulations, rulings and judicial decisions in effect at the date of this Proxy Statement/Prospectus. Future legislation or judicial or administrative changes or interpretations could alter or modify the statements and conclusions set forth herein. Any such changes or interpretations may or may not be retroactive and could affect the tax consequences to stockholders and unitholders as described herein. EACH STOCKHOLDER AND UNITHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER AND THE VISTA EXCHANGE DESCRIBED HEREIN INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGE OF APPLICABLE TAX LAWS. General. The Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. The Vista Exchange should constitute a transfer to a controlled corporation within the meaning of Section 351 of the Code. Midland has received a tax opinion from Arthur Andersen LLP, the tax advisors to the Vista Partnership, to the effect that the Merger will be treated as a reorganization within the meaning of Section 368(a) of the Code. No Private Letter Ruling is being sought from the Internal Revenue Service. No opinion is to be issued with respect to the Vista Exchange. The opinion is not binding on the Internal Revenue Service or the courts and therefore the delivery of such tax opinion cannot assure that the Internal Revenue Service or the courts will treat the Merger as a reorganization within the meaning of Section 368(a) of the Code. The tax opinion (as well as the description of tax consequences set forth herein) is based on, among other things, assumptions relating to certain facts and circumstances of, and the intentions of, the parties to the Merger, which assumptions either (i) have been made with the consent of Midland and the Vista Partnership or (ii) are based upon certain representations of fact made by the Vista Partnership, Midland or management of the Vista Partnership or Midland. It is a condition to the Merger that the opinion be delivered on the closing date of the Merger. If either the Vista Partnership or Midland waives the receipt of a tax opinion from Arthur Andersen LLP, it is the intent of both parties to postpone the Midland Meeting and supplementally provide additional disclosure to the Midland stockholders regarding the waiver of such tax opinion and the effect of such waiver. The material Federal income tax consequences of the Merger and the Vista Exchange should be as follows: Midland, the Vista Partnership and the General Partner. No gain or loss will be recognized by Midland, Vista, the General Partner or any of their respective subsidiaries as a result of the Merger. No gain or loss should be recognized by the Vista Partnership as a result of the Vista Exchange. Consequences to Holders of Midland Common Stock. The following discussion is a summary of the opinion of Arthur Andersen LLP, which is included herein as Appendix F. Except with respect to cash received in lieu of fractional shares, no gain or loss will be recognized by holders of Midland Common Stock upon the receipt of Vista Common Stock in the Merger. Gain or loss with respect to receipt of any cash in lieu of fractional shares is equal to the difference between the cash received and that portion of the stockholder's tax basis in the Midland Common Stock exchanged attributable to the fractional share interest deemed to 38 42 have been redeemed in the Merger. The tax basis of the Vista Common Stock received will equal to the basis of the Midland Common Stock surrendered in exchange therefor reduced by the amount of tax basis allocable to any fractional share interest deemed to have been issued and redeemed in the Merger. The holding period of the Vista Common Stock received will assume the holding period of the Midland Common Stock surrendered in the exchange therefor, provided that the Midland Common Stock surrendered was a capital asset in the hands of the exchanging shareholder. Consequences to Holders of Partnership Interests. The exchange of the Partnership Interests pursuant to the Vista Exchange should constitute a transfer to a controlled corporation within the meaning of Section 351 of the Code. Accordingly, under current law, no gain or loss should be recognized by holders of the Partnership Interests upon the exchange for Vista Common Stock, except that (i) any gain inherent in the exchange should be recognized to the extent of the fair market value of any Vista Warrants received and (ii) gain or loss should be recognized equal to the difference between any cash received in lieu of fractional share interest and the partnership interest holder's tax basis in the fractional share deemed to have been redeemed in the Vista Exchange. A holder's tax basis for the shares of Vista Common Stock received in the Vista Exchange should be the same as the holder's tax basis of its Partnership Interests exchanged therefor, decreased by (i) the fair market value of any Vista Warrants received (which Vista believes would be determined by the trading price of the Midland Warrants immediately after the Effective Time discounted to reflect that the Vista Warrants are not publicly traded) and (ii) the tax basis of any fractional share interest deemed to have been issued and redeemed and increased by the amount of gain (other than the gain recognized on the deemed redemption of any fractional share interest) recognized on the Vista Exchange. The holding period of the Vista Common Stock received should be a split holding period. The Vista Common Stock received by the holders of Partnership Interests attributable to the Vista Partnership's Section 751 assets should begin on the day after the Effective Time of the Merger. Based on current estimates Vista believes approximately 25% of the Vista Common Stock received by the holders of Partnership Interests will have a holding period beginning the day after the Effective Time of the Merger. The holding period attributable to the remaining Vista Common Stock should include the holding period of the Partnership Interests exchanged therefor, provided that the Partnership Interests exchanged were held as capital assets by the exchanging Vista Partnership limited partner. The tax basis of Vista Warrants received in the Vista Exchange should be their fair market value and their holding period should begin on the day after the Effective Time of the Merger. Consequences to Holders of GP Common Stock. The exchange of the GP Common Stock pursuant to the Vista Exchange should constitute a transfer to a controlled corporation within the meaning of Section 351 of the Code. Accordingly, under current law, no gain or loss should be recognized by holders of the GP Common Stock upon the exchange for Vista Common Stock, except that (i) any gain inherent in the transaction should be recognized to the extent of the fair market value of any Vista Warrants received and (ii) gain or loss equal to the difference between any cash received in lieu of fractional share interest and the stockholder's tax basis in the fractional share deemed to have been redeemed in the Vista Exchange. A holder's tax basis for the shares of Vista Common Stock received in the Vista Exchange should be the same as the holder's tax basis of the shares of its GP Common Stock exchanged therefor, decreased by (i) the fair market value of any warrants received (which Vista believes would be determined by the trading price of the Midland Warrants immediately after the Effective Time discounted to reflect that the Vista Warrants are not publicly traded) and (ii) the tax basis of any fractional share interest deemed to have been issued and redeemed and increased by the amount of gain recognized (other than the gain recognized on the deemed redemption of any fractional share interest) on the Vista Exchange. The holding period of the Vista Common Stock should include the holding period of the GP Common Stock exchanged therefor, provided that the GP Common Stock surrendered was a capital asset in the hands of the exchanging stockholder. The tax basis of Vista Warrants received in the Vista Exchange should be their fair market value and their holding period should begin on the day after the Effective Time of the Merger. 39 43 ACCOUNTING TREATMENT The Merger and the Midland Exchange will be accounted for as a purchase of Midland by Vista for financial accounting purposes. For presentation of certain anticipated effects of the accounting treatment on the consolidated financial position and results of operations of Vista after giving effect to the Merger and the Midland Exchange, see "Unaudited Pro Forma Combined Financial Statements." REGISTRATION RIGHTS The Merger Agreement provides that contemporaneously with the Closing, Vista shall enter into separate registration rights agreements (collectively, the "Registration Rights Agreements") with each of the stockholders of the General Partner and each of the limited partners of the Vista Partnership immediately prior to the Vista Exchange and with each holder of a Midland Exchange Stock Option covering (i) with respect to the Vista securityholders, the resale of shares of Vista Common Stock to be received by such securityholders pursuant to the terms of the Vista Exchange Agreement, together with all shares of Vista Common Stock issuable to such securityholders upon the exercise of an Exchange Warrant, (ii) with respect to the Midland securityholders, the resale of shares of Vista Common Stock issuable to such securityholders upon the exercise of an Exchange Warrant and (iii) any securities issued or issuable in respect of any such shares by way of any stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization or otherwise ((i), (ii) and (iii) above collectively referred to as the "Registrable Shares"). The Registration Rights Agreements provide that the holders of more than 50% of the Registrable Shares outstanding may, at any time after the first anniversary of the Effective Time, require Vista to effect the registration under the Securities Act of Registrable Shares on no more than two occasions by means of a "shelf" registration statement for an offering to be made on a continuous basis under the Securities Act, subject to certain limitations. The Registration Rights Agreements also provide certain "piggyback" registration rights to the holders of Registrable Shares whenever Vista proposes to register an offering of any of its capital stock under the Securities Act, subject to certain exceptions, including pro rata reduction if, in the reasonable opinion of the managing underwriter(s) of the offering, such a reduction is necessary to prevent an adverse effect on the marketability or offering price of all the securities proposed to be offered in the offering. The Registration Rights Agreements contain customary provisions regarding the payment of expenses by Vista and regarding mutual indemnification agreements between Vista and the holders of Registrable Shares for certain securities law violations. STOCK EXCHANGE LISTING It is a condition to the Merger that the shares of Vista Common Stock be authorized for listing on the ASE, subject to official notice of issuance. Application has been made for such listing. RESTRICTIONS ON RESALES BY AFFILIATES The shares of Vista Common Stock to be received by Midland stockholders in connection with the Merger have been registered under the Securities Act and, except as set forth in this paragraph, may be traded without restriction. The shares of Vista Common Stock to be issued in connection with the Merger and received by persons who are deemed to be "affiliates" (as that term is defined in Rule 144 under the Securities Act) of the Vista Partnership or Midland prior to the Merger may be resold by them only in transactions permitted by the resale provisions of Rule 145 under the Securities Act (or, in case any such person should become an affiliate of Vista, Rule 144 under the Securities Act) or as otherwise permitted under the Securities Act. Accordingly, the Merger Agreement provides that each of the Vista Partnership and Midland will use all reasonable efforts to cause its affiliates to execute an agreement to the effect that such persons will not sell any shares of Vista Common Stock at any time in violation of the Securities Act or the rules and regulations promulgated thereunder, including Rule 145. 40 44 DISSENTERS' RIGHTS Under Texas law, holders of Midland Common Stock will not be entitled to any dissenters' rights in connection with the Merger. Section 5.11 of the Texas Business Corporation Act provides that stockholders have the right to dissent from any plan of merger that requires stockholder approval. Notwithstanding the foregoing, however, Section 5.11 provides that a stockholder shall not have the right to dissent from a plan of merger if (i) the stockholder is not required to accept for the stockholder's shares any consideration that is different from the consideration to be provided to any other stockholder and (ii) the stockholder will receive as consideration shares of stock that are listed, or authorized for listing upon official notice of issuance, on a national securities exchange.

See "The Midland Meeting -- Solicitation of Proxies." 41 45 VISTA GENERAL Vista is a newly formed Delaware corporation and wholly owned subsidiary of the Vista Partnership that has not, to date, conducted any significant activities other than those incident to its formation, its execution of the Merger Agreement, the Midland Exchange Agreement and the Vista Exchange Agreement and its participation in the preparation of this Proxy Statement/Prospectus. Vista has no material assets or liabilities, other than its rights and obligations under the Merger Agreement, the Midland Exchange Agreement and the Vista Exchange Agreement, and has not generated any material revenues or expenses. The Merger, the Midland Exchange and the Vista Exchange will create a newly formed independent oil and gas company by combining the oil and gas reserves, operations and businesses of the Vista Partnership and Midland. Vista's growth strategy involves a coordinated balance of acquisitions, exploitation and exploration. Drilling and production operations will be located in Texas and New Mexico. STRENGTHS AND STRATEGIES Vista's principal strengths and strategies will be the following: Reserves and Production - Vista will have over 14.0 MMBOE of total proved reserves, comprised of 25.2 Bcf of natural gas and 9.9 MMBbls of crude oil, with a PV10 of approximately $56.4 million. - Vista's daily production is expected to be over 1,800 Bbls of oil and 5,200 Mcf of natural gas. - Vista's reserve base will be approximately 30% natural gas and 70% crude oil. - Vista's aggregate reserve to production ratio will be approximately 13 years. A significant benefit of owning long-lived reserves is an enhanced ability to provide long-term funding for additional growth opportunities. - More than 90% of Vista's total proved reserves will be concentrated in the Permian Basin of West Texas and Southeastern New Mexico, a premier oil and gas producing province typified by numerous long-life, multi-pay exploitation and exploration opportunities. - Vista will operate over 400 producing wells, representing over 92% of its total proved reserves and increasing its control over the implementation of its strategies and projects. Management - Vista's management team will be led by C. Randall Hill, Steven D. Gray and R. Cory Richards, the current Chairman and Chief Executive Officer, President, and Vice President -- Exploration, respectively, of the General Partner of the Vista Partnership. - Vista's management team is well-rounded and experienced with professional backgrounds in law, petroleum engineering and geology, and over 35 years of collective experience in the oil and gas industry. - The members of this management team will collectively own approximately 13% of the Vista Common Stock, thereby aligning their interests with those of the other Vista stockholders. Virtually all of the management team's net worth will consist of their respective ownership in Vista and they have no outside business interests, making them very focused on growing the equity value of Vista. NGP's Ownership - NGP will own approximately 52% of the Vista Common Stock and will be Vista's largest stockholder upon consummation of the Merger. 42 46 - NGP enjoys a reputation as an active and experienced investor in the oil and gas industry. - Three of NGP's principals, Kenneth A. Hersh, David R. Albin and John S. Foster, will serve as directors of Vista. Vista considers NGP's continued participation in the ownership and management of Vista to be of substantial value, particularly in the areas of corporate finance activities, access to financial markets and building sponsorship for Vista in the public arena. OBJECTIVES AND GROWTH STRATEGY - Vista's primary corporate objective will be to rapidly expand its reserve base, production capacity, cash flow and earnings in order to substantially increase the value of the Vista Common Stock. - Vista's management will continue to employ the same business philosophies, techniques and strategies that have grown the Vista Partnership and its predecessor from a start up company with no reserves or initial cash flow in December 1992 to a company of over 9.1 MMBOE and $3.9 million of EBITDAEX for 1997. - Vista's strategy involves these basic components: (i) acquiring domestic, proved oil and gas properties with realizable upside potential; (ii) exploiting such properties through a comprehensive program of workovers, recompletions, developmental and exploratory drilling, and secondary recovery projects using sophisticated technology; (iii) reducing costs at all levels of its business; and (iv) internally generating exploration projects where Vista can operate and control the timing and costs of such exploration efforts. - Vista will be committed to continuing to enhance stockholder value through adherence to its strategy and believes that its expected inventory of development, exploitation and exploratory projects, along with strategic acquisition opportunities that may arise in the future, may provide significant opportunity for future growth in value.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS JUNE 30, 1998, AND DECEMBER 31, 1997 1. BASIS OF PRESENTATION: The Vista Partnership has entered into the Merger Agreement with Midland that provides for Midland to become a subsidiary of Vista, currently a newly created subsidiary of the Vista Partnership. The Merger will require Merger Sub to be merged into Midland, resulting in Midland becoming a subsidiary of Vista. As contemplated by the Merger Agreement, each of the limited partners of the Vista Partnership and each of the stockholders of the General Partner have entered into separate exchange agreements pursuant to which each such holder's Partnership Interests and shares of GP Common Stock will be exchanged for shares of Vista Common Stock contemporaneously with the Merger. As a result of the Merger and the Vista Exchange, Vista, a new publicly held oil and gas exploration and development company will be created. The unaudited pro forma combined balance sheet of Vista as of June 30, 1998, has been prepared to give effect to the Merger, the Midland Exchange and the Vista Exchange as if they had occurred on June 30, 1998. In accordance with the provisions of APB No. 16, "Business Combinations," the Merger and the Midland Exchange have been accounted for as a purchase of Midland by the Vista Partnership. The unaudited pro forma combined statements of operations of Vista for the six months ended June 30, 1998, and for the year ended December 31, 1997, have been presented to give effect to the Merger, the Midland Exchange and the Vista Exchange and certain events described below for the Vista Partnership and Midland as if the Merger, the Midland Exchange and the Vista Exchange and such events had occurred on January 1, 1997. The following is a description of the individual columns included in these unaudited pro forma combined financial statements: THE VISTA PARTNERSHIP -- Represents the consolidated balance sheet of the Vista Partnership as of June 30, 1998, and the consolidated statements of operations of the Vista Partnership for the six months ended June 30, 1998, and for the year ended December 31, 1997. MIDLAND -- Represents the consolidated balance sheet of Midland as of June 30, 1998, and the consolidated statements of operations of Midland for the six months ended June 30, 1998, and for the year ended December 31, 1997. 1997 ASSETS ACQUIRED -- Reflects the results of operations for the year ended December 31, 1997, from certain oil and gas properties prior to their acquisition in 1997. In May 1997, the Partnership acquired interests in certain oil and gas properties from Coastal Oil and Gas Corporation for a net purchase price of $1.1 million. Also, in July 1997, the Vista Partnership acquired interests in certain oil and gas properties from E.G. Operating for a net purchase price of $6.1 million. Prior to their acquisition in 1997, the oil and gas properties so acquired produced 63,864 Bbls of oil and 256,440 Mcf of gas. Average prices of $16.15 per Bbl of oil and $1.91 per Mcf of gas were received from such production and production costs per BOE of $3.23 were incurred. 1997 ASSETS SOLD -- Reflects the results of operations for the year ended December 31, 1997, from certain oil and gas properties prior to their sale in 1997. During the year ended December 31, 1997, Midland sold certain nonstrategic oil and gas properties for aggregate proceeds of approximately $563,000. Prior to their sale in 1997, these oil and gas properties produced 3,326 Bbls of oil and 56,263 Mcf of gas. Midland received an average price of $17.87 per Bbl of oil and $2.37 per Mcf of gas from such production and incurred production costs per BOE of $5.79 and depletion expense per BOE of $2.27 related to these properties. 51 55 VISTA ENERGY RESOURCES, INC.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (ii) Vista warrants are valued at $0.76 per warrant which represents Midland's seven-day average stock purchase warrant trading price surrounding the announcement of the Merger on May 26, 1998. (iii)Employee Stock Options are valued at $2.29 per option which represents the fair value of outstanding Stock Options using the Black-Scholes option-pricing model as of the announcement of the Merger on May 26, 1998, using the following weighted-average assumptions: Expected Volatility......................................... 78% to 99% Risk Free Rate.............................................. 5.50% to 5.58% Expected Life............................................... 3 to 5 years Expected Dividend Yield..................................... 0% (iv) Vista common stock warrants are valued at $0.55 per warrant which represents the average difference of the in-the-money warrant strike prices from the value of the Vista Common Stock as defined in (a). The following table represents the preliminary allocation of the total purchase price of Midland to the acquired assets and liabilities. The allocation represents the fair values assigned to each of the significant assets acquired and liabilities assumed. Any future adjustments to the allocation of the purchase price are not anticipated to be material to the unaudited pro forma combined financial statements.

PRO FORMA ENTRIES: (a) To adjust Midland's historical balances to reflect the fair market value of the assets acquired, liabilities assumed, and the new capital structure using the purchase method of accounting based on the aggregate purchase consideration as discussed in Note 2. All net working capital balances were estimated to approximate fair market value at the time of acquisition. The historical goodwill, contracts and leases, and other assets balances were eliminated as it was determined that these items did not provide any continuing value to Vista. Unearned compensation was eliminated as it related to the unamortized portion of Midland's stock-related compensation expense that is not applicable to Vista. (b) To record deferred taxes related to the differences between the historical tax basis of assets acquired and liabilities assumed and the fair market value allocated to the assets acquired and liabilities assumed based on the aggregate purchase consideration as discussed in Note 2. (c) To record cash consideration for non-recurring merger expenses related to the Warley Settlement Agreement as described on page 36 and legal, accounting, registration, and other costs directly related to the Midland acquisition. 53 57 VISTA ENERGY RESOURCES, INC. NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED) (d) To record all assumed debt as long-term under Vista's Amended and Restated Credit Agreement, dated August 15, 1997. (e) To record the deferred tax liability and related provision for income taxes to reflect the change in Vista's tax status from a partnership to a corporation. (f) The accompanying unaudited pro forma financial statements have been prepared pursuant to regulations prescribed by the Securities and Exchange Commission. The unaudited pro forma statements of operations do not consider the effects of the cost reduction plans of management to be implemented after closing. Management expects to reduce lease operating expenses by approximately $210,000 on an annual basis for efficiencies to be realized through economies of scale in common operating locations and reductions of certain field personnel. In addition, management expects to reduce general and administrative expenses by approximately $1,475,000 on an annual basis from the elimination of redundant personnel, lease space and other corporate services. In accordance with Securities and Exchange Commission regulation, none of these anticipated cost reductions have been reflected in the accompanying pro forma statements of operations. (g) To reclassify certain COPAS overhead charges to conform with the financial statement presentation of Vista. (h) To adjust depreciation, depletion and amortization expense for the additional basis allocated to the oil and gas properties acquired and accounted for using the successful efforts methods of accounting. (i) To adjust impairment of oil and gas properties to reflect the restatement of the Midland properties in purchase accounting as if the Merger had occurred on January 1, 1997. Midland's historical impairment charges were required under SFAS No. 121 which requires a review for impairment on a property by property basis. Although the fair value of Midland's oil and gas properties may have exceeded its cost in total, Midland recorded an impairment because of the property by property nature of the impairment test required by SFAS No. 121. In accordance with APB No. 16, the purchase consideration in the Merger has been allocated to the assets and liabilities acquired based on estimated fair values as detailed in Note 2. This allocation results in approximately $36.9 million recorded to oil and gas properties on a pro forma basis after the fair value of other assets and liabilities acquired was determined. The purchase price attributed to oil and gas properties was allocated to groups of properties based on relative fair values. Based on estimated future cash flow, management does not believe any impairment charge under SFAS No. 121 is required on a pro forma basis for the Midland properties. Vista could be required to recognize an impairment charge in the future depending on future expected prices and costs and production estimates. Due to the significance of the write-up of Midland's oil and gas properties, such an impairment charge could be significant, if required. (j) To adjust interest expense to be reflective of the weighted average interest rate received under Vista's Amended and Restated Credit Agreement, dated August 15, 1997. Midland's weighted average indebtedness for the six months ended June 30, 1998 and the year ended December 31, 1997 was $9.5 million and $8.6 million, respectively. The applicable interest rate under Vista's Amended and Restated Credit Agreement, dated August 15, 1997, for both periods was 7.6%. (k) To remove gain on 1997 Assets sold as described in footnote (m). (l) To record revenue and direct operating expenses for the 1997 Assets Acquired based on the actual results of operations prior to their acquisition. (m) To reduce revenue and direct operating expenses for the 1997 Assets Sold based on the actual results of operations prior to their sale. 4. INCOME TAXES: Vista will account for income tax in accordance with the provisions of SFAS 109. In accordance with SFAS 109, Vista will prepare separate tax calculations for each tax jurisdiction in which Vista will be subject to income taxes. 54 58 VISTA ENERGY RESOURCES, INC. NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED) 5. OIL AND GAS RESERVE DATA: The estimates of Midland's proved oil and gas reserves, which are located entirely within the United States, were prepared in accordance with the guidelines established by the Commission and Financial Accounting Standards Board. The estimates of December 31, 1997 are based on evaluations prepared by Williamson Petroleum Consultants, Inc., independent petroleum engineers. The estimates as of December 31, 1996 and 1995, are based on evaluations prepared by E. Ralph Green and Associates, independent petroleum engineers. For information concerning costs incurred by Midland for oil and gas operations, net revenues from oil and gas production, estimated future net revenues attributable to Midland's oil reserves and present value of future net revenues on a 10% discount rate and changes therein, see Notes to Midland's consolidated financial statements. Midland 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 subject to change as further information becomes available. The estimates of the Vista Partnership's proved oil and gas reserves, which are located entirely within the United States, were prepared in accordance with the guidelines established by the Commission and Financial Accounting Standards Board. The estimates of December 31, 1997, 1996 and 1995 are based on evaluations prepared by the Vista Partnership. For information concerning costs incurred by the Vista Partnership for oil and gas operations, net revenues from oil and gas production, estimated future net revenues attributable to the Vista Partnership's oil reserves and present value of future net revenues on a 10% discount rate and changes therein, see Notes to the Vista Partnership's consolidated financial statements. The Vista Partnership 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 subject to change as further information becomes available. The following unaudited pro forma supplemental information regarding the oil and gas activities of Vista is presented pursuant to the disclosure requirements promulgated by the Commission and Statement of Financial Accounting Standards No. 69, "Disclosures About Oil and Gas Producing Activities." Management emphasizes that reserve estimates are inherently imprecise and subject to revision 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; such changes could be significant.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED) Standardized measure of discounted future net cash flows The pro forma combined standardized measure of discounted future net cash flows is computed by applying year-end prices of oil and gas (with consideration of price changes only to the extent provided by contractual arrangements) to the estimated future production of oil and gas reserves less estimated future expenditures (based on year-end costs) to be incurred in developing and producing the proved reserves discounted using a rate of 10% per year to reflect the estimated timing of the future cash flows. Future income taxes are calculated by comparing discounted future cash flows to the tax basis of oil and gas properties, plus available carryforwards and credits, and applying the current tax rate to the difference.

(b) Gain (loss) on sale of properties was principally composed of the loss on the sale of Midland's former office facilities in Midland, Texas, in 1995 and a gain on the sale of a working interest in an oil and gas property to Summit Petroleum Corporation in 1994. In 1997, gains were realized primarily from the sale of oil and gas properties. (c) In 1994, there was other income from the settlement of litigation regarding a former property operator of $120,090. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF MIDLAND Plan of Operations During 1996 and 1997, Midland's exploration efforts consumed most of its available resources. While Midland believes its exploratory efforts have identified possible future drilling opportunities, its ability to actively pursue these efforts as well as to actively exploit existing developed properties is dependent upon securing additional capital. Beginning in early 1997, Midland determined that it should explore strategic alternatives to raising capital though sales of equity. To assist Midland, it engaged an investment banking firm. During 1997 and continuing into 1998, Midland considered various alternative transactions, primarily consisting of the sale of all or substantially all of its assets, acquisitions of another smaller company, merging with a company of equal size and merging with a larger company. Midland terminated its contract with its investment banking firm in December 1997. On May 22, 1998, Midland entered into the Merger Agreement with the Vista Partnership. Consummation of the Merger is subject to approval of Midland's stockholders. If the transaction with Vista is not consummated, Midland expects to restrict its operations, including future development, to a level that its current operations can support, and continue to seek a strategic transaction as well as consider the sale of equity. Midland's initial capitalization was through the acquisition of interests of the seven public oil and gas income limited partnerships in exchange for common stock and warrants of Midland. There were 2,265,522 shares of common stock issued and, for each share of common stock issued, two warrants were issued entitling the holder to purchase one share of common stock at $2.50 and one share at $4.00 during the period November 1990 to November 2002. In October, 1995, Midland called for redemption of its $2.50 warrants. Holders received a redemption payment of $0.05 per warrant for aggregate payments of $63,373, which was charged to additional paid in capital. 997,009 of the $2.50 warrants were exercised, resulting in net proceeds of approximately $1,831,000. As of March 31, 1998, 11,428 of the $4.00 warrants had been exercised. On December 31, 1993, Midland acquired all of the issued and outstanding common stock of Midland Resources Operating Company, Inc. ("MRO") through an agreement of acquisition under which Midland issued 1,110,000 shares of common stock to Deas H. Warley III and another former officer and director of Midland. The exchange was based on the relative fair values of Midland and MRO, based on a determination by the Board of Directors of each respective corporation. The overall transaction was subject to a fairness opinion provided by an investment banking firm. The acquisition of MRO expanded Midland's revenue base to include property operations. On December 20, 1996, Midland completed the acquisition of Summit Petroleum Corporation ("Summit"), an affiliated entity engaged in oil and gas acquisition, development and exploration activities, which owned interests in many of the same properties as Midland. Midland's total cash investment in acquiring Summit was approximately $2,011,000. (See Note B of the Notes to the Consolidated Financial Statements.) 58 62 Capital Resources and Liquidity Historically, Midland's sources of liquidity have been from both bank debt financing and operations. However, low product prices in recent months, coupled with the costs of its exploration program in 1996 and 1997 have had severe adverse effects on its liquidity. Midland presently has no readily available sources of additional capital resources and no commitments for capital expenditures, and intends to incur only those costs required to maintain necessary business operations and production from its properties. Net cash provided by operations decreased from $1,893,641 in 1996 to $1,393,461 in 1997, for a decrease of $500,180, reflecting decreased oil and gas production and pricing, and increased production costs and interest expense, partially offset by lower geological and geophysical costs. Net cash used in investing activities decreased from 1996 by $3,147,583, reflecting greater proceeds from property sales in 1997 and the purchase of Summit in 1996. Net cash provided by financing activities decreased from 1996 by $2,715,257, reflecting additional borrowings for property acquisition and development in 1997 and greater debt repayments resulting primarily from the sale of the Redfish Bay properties in 1997. In 1997, acquisition costs for proved properties were $34,993, acquisition costs for unproven properties were $836,863 and development costs were $1,716,294. Also, $1,536,130 was invested in an oil and gas limited partnership in 1997. In 1996, cash payments for oil and gas property acquisition costs totaled $761,476 for proved properties, $144,100 for unproved properties, and $2,808,534 for development of properties. In the first half of 1998, cash flow was a negative $94,217. Cash flow from operations was a negative $24,288, which includes the positive effects of a decrease in accounts receivable of $338,671 and the negative effects of a net decrease in accounts of $254,673. Lower oil prices have had a significant adverse impact on operating cash flows. Investing activities required the use of $144,653 in cash due primarily to merger costs of $296,332 in connection with the proposed Vista transaction, partially offset by proceeds from the sales of properties in excess of capital additions. Financing activities resulted in a net increase in cash of $74,924 due primarily to bank borrowings of $720,000, which were used to fund capital expenditures and merger costs. Repayments of bank debt of $651,615 were funded primarily from the proceeds of a December 1997 property sale. For 1997, Midland's working capital increased by $95,170 over 1996 to $471,462. The principal components of this increase was the positive impact of approximately $400,000 resulting from the sale of the Redfish Bay property in 1997, which was offset by a reduction in current deferred tax assets of $341,000. At June 30, 1998, Midland's working capital had decreased to a negative $487,944. This was due primarily to the adverse impact on revenue of lower oil prices during the first half of 1998, and an increase in current debt maturities under Midland's revolving credit agreement with its bank, resulting from a reduction in borrowing base which was also due to current low oil prices. Management believes current debt maturities can be funded from cash flow from operations. Management also believes that its credit facilities and its cash flow from operations are adequate to meet its liquidity needs and, to the extent necessary, additional operational changes will be made. Any future drilling will depend on Midland's ability to raise additional capital through bank borrowings, private placements or merger transactions. At December 31, 1997, Midland has a net deferred tax asset of $1,048,193 which it believes can be realized based on estimates of future income from the production of existing hydrocarbon reserves. The net asset is primarily composed of net operating loss carry-forwards which do not begin to expire until 2005. Midland has a revolving credit agreement with Compass Bank, which provides for a credit facility of $30,000,000 and an initial borrowing base of $10,500,000. Effective June 1, 1998, the borrowing base was reduced to $9,800,000 with scheduled monthly reductions of $80,000 per month beginning August 1, 1998. The borrowing base is subject to redetermination in November and May of each year. Amounts borrowed under this agreement are collateralized by a first lien on substantially all of Midland's oil and gas properties. Interest under this agreement is payable monthly at an annual rate which, at Midland's option, is equal to (a) Compass Bank's index lending rate (8.5% on June 30, 1998), or (b)the London Interbank Offered Rate ("LIBOR"), plus 2.5%. In addition, a commitment fee equal to 1/2% per annum on the unused portion of the 59 63 borrowing base is required. This agreement also requires that Midland maintain certain financial ratios and generally restricts Midland's ability to incur debt, sell assets, materially change the nature of Midland's business structure or pay dividends. As of June 30, 1998, the balance due under this agreement was $9,720,000 and currently is $9,640,000. On March 1, 1995, Midland entered into a one year gas swap agreement to hedge against a portion of the price risk associated with gas price declines. This swap agreement expired in February 1996, and Midland has not entered into another contract. Losses under this contract were $21,109 and $25,860 for 1995 and 1996, respectively. The prices of crude oil have fluctuated significantly in recent years as well as in recent months. As of June 30, 1997, Midland was receiving $18.60 per Bbl as compared to $25.00 at January 1, 1997. At June 30, 1998, Midland was receiving approximately $12.00 per Bbl as compared to $16.52 at January 1, 1998. Fluctuations in price have a significant impact on Midland's financial condition and liquidity. The following tables set forth a summary of historical financial information for Midland. These tables should be read in conjunction with the consolidated financial statements of Midland Resources, Inc. and Subsidiaries (and the related notes). It should be noted that there are no audited financial statements included herein for the year 1994. These tables are not covered by the reports of independent certified public accountants.

(b) Gain (loss) on sale of properties was principally composed of the loss on the sale of Midland's former office facilities in Midland, Texas, in 1995 and a gain on the sale of a working interest in an oil and gas property to Summit Petroleum Corporation in 1994. In 1997, gains were realized primarily from the sale of oil and gas properties. (c) In 1994, there was other income from the settlement of litigation regarding a former property operator of $120,090. Year 2000 Compliance. Midland does not expect that the cost of converting its computer system to Year 2000 compliance will be material to its financial condition. Midland believes it will be able to achieve Year 2000 compliance by the end of 1998 for an amount less than $10,000, and it does not currently anticipate any disruption in its operations as the result of any failure by Midland to be in compliance. Midland does not currently have any information concerning the Year 2000 compliance status of its customers and vendors. Results of Operations -- Years ended December 31, 1995, 1996 and 1997 During 1996, oil and gas sales increased from $5,147,033 in 1995 to $6,958,491; an increase of $1,811,458 or 35%. Oil production increased from 166,652 Bbls to 215,913 Bbls; an increase of 49,261 Bbls or 30%. Gas production decreased from 1,268,772 Mcf to 1,002,482 Mcf; a decrease of 266,290 Mcf or 21%. Sales and net production increases resulted from price increases as well as from production from wells drilled and completed in the Jameson Field, and the Wallace and Wilson properties in late 1995 and early 1996. Average gas prices 61 65 increased from $1.79 per Mcf in 1995 to $2.39 per Mcf in 1996. Oil prices increased from $17.28 per Bbl in 1995 to $21.15 per Bbl in 1996. During 1997, oil and gas sales decreased from $6,958,491 to $6,396,249; a decrease of $562,242, or 8%. Oil production decreased from 215,913 Bbls to 192,580 Bbls; a decrease of 23,333 Bbls, or 11%. Gas production decreased from 1,002,482 Mcf to 988,109 Mcf; a decrease of 14,373, or 1%. The purchase of Summit resulted in production increases of 7,959 Bbls and 72,711 Mcf. However, this increase, as well as increases from new wells drilled in 1997, were more than offset by production declines on most wells. Average oil prices declined from $21.15 in 1996 to $19.74 in 1997. Average gas prices increased from $2.39 in 1996 to $2.63 in 1997. For 1997, Midland's share of income from an oil and gas limited partnership was $72,275 which included oil and gas sales of $119,356 from approximately 6,400 Bbls of oil produced. There was no similar item in 1996. Property operations income, which is comprised of administrative overhead fees charged to third parties who own interests in properties for which Midland serves as operator, increased from $111,862 in 1996 to $119,012, an increase of $7,150, or 6%. In 1996, production costs increased from $2,509,854 in 1995 to $2,981,837, an increase of $471,983 or 19%. This increase is attributable primarily to additional producing wells as discussed above, as well as to production taxes increasing as a result of increased oil and gas prices. In 1997, production costs increased from $2,981,837 in 1996 to $3,088,886, an increase of $107,049 or 4%. This was due to major repairs and workovers conducted in 1997, partially offset by decreased production costs resulting from the sale of Redfish Bay. During 1997 and 1996, exploration costs and abandonments were $943,294 and $766,855, respectively, which were incurred in connection with the 3-D exploration projects discussed above. These amounts include dry hole costs of $796,852 in 1997 and $416,892 in 1996. Abandonment costs in 1997 were comprised of expired and worthless leasehold acreage totaling $93,760. In 1996, depreciation depletion and amortization (DD&A) was $1,306,287 as compared to $1,033,905 in 1995, for an increase of $272,382 or 26%. This was due primarily to an increase in property investments resulting from the completion of additional wells and to the acquisition of Summit. In 1997, DD&A was $1,964,658, an increase of $658,371 from 1996, or 50%. This was due to (i) lower oil and gas reserves at December 31, 1997, which was due primarily to lower oil and gas prices at December 31, 1997, and (ii) to less than desired economic success on some wells drilled in 1997. In 1996, general and administrative (G&A) expenses increased from $1,049,904 in 1995 to $1,295,298, an increase of $245,394 or 23%. This increase was attributable primarily to the write off in 1996 of approximately $115,000 of acquisition costs associated with an attempt to acquire another public independent oil and gas company, as well as to increased labor costs associated with Midland's relocation from Midland, Texas, to Houston, Texas. In 1997, G&A expenses were $1,451,404 for an increase of $156,106, or 12%, over 1996. This was due primarily to increased legal and consulting fees, and to non-cash stock based compensation expense of $217,484. These costs were partially offset by lower costs in other areas due to cost reduction measures. Impairment losses were $1,020,670 in 1995, $114,904 in 1996 and $1,277,342 in 1997. Impairments are recognized when estimated future net cash flows on individual properties are less than their net capitalized cost. When this situation exists, impairment losses are recognized on each such property as the difference between the property's net capitalized cost and its estimated fair value. This is required by accounting rules even though aggregate reserve values far exceed net capitalized costs for all properties taken as a whole. In 1997, there were gains of $462,571 primarily from the sales of oil and gas properties, including $349,000 from the sale of the Redfish Bay property. Midland also sold all of its Colorado working interests. These sales were made so that Midland could focus its resources on its west Texas property interests. The cash proceeds from these two sales, which totaled approximately $2,200,000, were used to reduce bank debt. In 1996, interest expenses increased to $722,447, an increase of $110,860, or 18% from 1995. This increase is attributable to additional borrowings to consummate the Summit acquisition and for property 62 66 acquisitions and development projects in 1996. In 1997, interest increased to $970,430, an increase of $247,983, or 34%, due primarily to additional borrowings to fund Midland's drilling program in 1997 and to pay $84,800 to close an interest rate swap contract. In 1995, the net loss was $737,031 primarily resulting from an impairment loss of $1,020,670, the loss on sale of properties and equipment of $102,984 and the incurrence of exploration costs totaling $198,453: In 1996, net income was $22,122, due primarily to higher prices for oil and gas production and lower impairment losses, partially offset by increases in production costs, G&A expenses and other factors discussed above. In 1997, the net loss was $1,883,382, due primarily to property impairments, DD&A, lower oil and gas production, exploratory dry holes and other factors discussed above. Results of Operations -- Six Months Ended June 30, 1998 and 1997 Net loss increased from $82,483 in the first half of 1997 to $565,769 in the first half of 1998. Individual categories of income and expenses are discussed below. Oil and gas sales decreased from $3,346,815 in the first six months of 1997 to $2,182,394 in the same period of 1998. This decrease of $1,164,421 or 35% resulted from decreased oil and gas prices and gas production. Oil and gas production quantities were 94,791 Bbls and 515,982 Mcf in 1997 and 94,714 Bbls and 435,522 Mcf in 1998, a decrease of 77 Bbls and a decrease of 80,460 Mcf or 16%. The decline in gas production is due primarily to properties sold in December 1997, as well as to normal production declines on most properties. Average gas prices decreased from $2.62 per Mcf in 1997 to $2.01 per Mcf in 1998, while average oil prices decreased from $20.91 per Bbl in 1997 to $13.78 per Bbl in 1998. In the first six months of 1997, the Company's share of net income from an oil and gas limited partnership was $99,007 which included oil revenue of $115,875 from 6,195 Bbls of production. There was no similar item in 1998. Production costs decreased from $1,449,529 in the first six months of 1997 to $1,416,724 for the same period of 1998, a decrease of $32,805 or 2%. In the first half of 1997, exploration costs were $360,284, which included $332,194 in exploratory dry hole costs and $28,090 in geological and geophysical costs. In the first half of 1998, exploration costs were $4,709 and costs of plugging uneconomical wells was $39,808. G&A decreased from $817,183 in the first six months of 1997 to $574,837 in the same period of 1998, a decrease of $242,346 or 42%. These totals included non-cash stock based compensation charges of $117,047 in 1997 and $55,398 in 1998. Other reductions resulted from cost curtailment measures instituted in the fourth quarter of 1997. DD&A based on production and other methods increased from $634,233 in the first six months of 1997 to $678,255 in the same period of 1998, an increase of $44,022 or 7%, due primarily to lower reserve quantity estimates. At June 30, 1997, the Company provided for impairment losses on its oil and gas properties of $356,000. There was no similar item in 1998. In the first half of 1997, the Company reported gains from sales of property of $376,505 of which $349,079 was from the sale of the Redfish Bay property in February of 1997. The gain from asset sales in the first half of 1998 was $10,048. BUSINESS AND PROPERTIES OF MIDLAND Business Description Midland is an independent oil and gas company engaged primarily in the exploration and development of domestic oil and gas. Midland, incorporated June 5, 1989, was organized in 1990 with the issue of common 63 67 stock and warrants in exchange for the partnership interests of seven former public oil and gas limited partnerships. Midland's initial emphasis was on acquisition and exploitation of oil and gas properties. In 1995, Midland changed its emphasis to exploration, utilizing 3-D seismic technology. On December 20, 1996, Midland completed the acquisition of Summit Petroleum Corporation, an affiliate, for cash. (See Note F. Related Parties, to Consolidated Financial Statements) Although Midland's principal properties are located in Texas, Midland also owns working interest and minor royalty leasehold interests in developed and undeveloped oil and gas acreage in Illinois and Colorado. Properties Reserves. The estimates of Midland's proved oil and gas reserves, which are located entirely within the United States, were prepared in accordance with the guidelines established by the Commission and Financial Accounting Standards Board. The estimates of December 31, 1997 are based on evaluations prepared by Williamson Petroleum Consultants, Inc., independent petroleum engineers. The estimates as of December 31, 1996 and 1995, are based on evaluations prepared by E. Ralph Green and Associates, independent petroleum engineers. For information concerning costs incurred by Midland for oil and gas operations, net revenues from oil and gas production, estimated future net revenues attributable to Midland's oil reserves and present value of future net revenues on a 10% discount rate and changes therein, see Notes to Midland's consolidated financial statements. Midland 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 subject to change as further information becomes available. Midland's proved reserves totaled 5.0 million BOE at December 31, 1997 with an PV10 of $17.8 million. Reserves decreased 16% versus year end 1996. Oil reserves were 2.7 MBOE (a 7% decrease from 1996) while gas reserves were 13.9 Bcf (a 24% decrease from 1996). On a BOE basis Midland's proved reserves at December 31, 1997 are 67% proved developed with 33% being proved undeveloped. 53% of Midland's reserves are oil and 47% are gas. Over 99% of Midland's reserve value is attributable to operated properties. Only 1% of Midland's reserve value is attributable to properties operated by others. The following table summarizes the estimated proved reserves and estimated future cash flows associated with Midland's oil and gas properties as estimated in accordance with the definitional requirements under rule 4-10(a) of Regulation S-X. 1997 AVERAGE DAILY PROVED RESERVES AS OF DECEMBER 31, 1997 PRODUCTION --------------------------------------- ---------------------- NATURAL PV10 NATURAL OIL GAS VALUE OIL GAS (MBbls) (MMcf) MBOE (000) (Bbls) (Mcf) BOE -------- -------- ------ -------- ------ ------- --- Total Net to Midland's................... 2,655 13,860 4,965 $17,765 528 2,707 979 In estimating oil reserves for 1997, a price of $16.52 per barrel was used, which is the average actual price in effect for Midland's oil production on January 1, 1998. In estimating gas reserves for 1997, a price of $2.36 per Mcf was used, based on prices in effect for Midland's gas on January 1, 1998. As an operator of domestic oil and gas properties, Midland has filed Form EIA-23, "Annual Survey of Oil and Gas Reserves," with the Department of Energy as required by Public Law 93-275 and Public Law 95-91. There are differences between the reserves reported on Form EIA-23 and the reserves reported herein. These differences are due to the fact that Form EIA-23 requires and operator to report on total reserves attributable to wells which are operated by it without regard to ownership. The reserves reported herein are based on Midland's net ownership interest therein. 64 68 Production. Midland's production for 1997 averaged 979 BOE per day. Production decreased during the year from 1,064 BOE per day in January 1997 to 986 BOE per day average for December 1997 representing a 7% decrease for the year. Based on end of the year production rates Midland's proved reserves to production ratio is 13.8 years on a BOE basis. This ratio was up from 12.9 years for year end 1996. Description of Properties. Midland's principal properties are located in Texas. Midland also owns working interest and minor royalty leasehold interests in developed and undeveloped oil and gas acreage in Illinois and Colorado. Midland has no properties outside the United States. The following is a general description of Midland's principal properties. PERMIAN BASIN Chalk Mountain 3-D Seismic Exploration and Development Project Midland held acreage adjoining a project generated by Texland Oil & Gas Co. as a 3-D seismic exploration project in July 1996 in Sterling, Tom Green and Reagan Counties, Texas. Midland has acquired a 52.75% working interest in approximately 3,300 acres in this project. During 1997, Midland invested approximately $2,000,000 in acquisition costs and drilling of three exploratory wells and one development well in this project. One of these wells was successful in the Fusselman formation. One of the wells established production in the Canyon formation, but due to low production volume, additional Canyon wells are not economically justified. Two of these wells were dry holes. In the first quarter of 1998, Midland acquired additional acreage in the project based on review of 3-D seismic data. Latigo 3-D Seismic Exploration and Development Project This project was defined and acquired as a 3-D seismic exploration project in 1995 in the Northwest Shelf area of the Permian Basin in Hockley County, Texas. The seismic survey covered 12 square miles and resulted in the leasing of approximately 4,700 acres. Two successful exploratory wells were drilled in this project in 1997 at a cost to Midland of approximately $1,568,000. Average daily production from the discoveries drilled in this project in 1997 was 163 BOPD. Midland owns a 55% working interest in this project. Sunburst 3-D Seismic Exploration and Development Project The Sunburst project was acquired as a 3-D seismic exploration project in 1995 in the Northwest Shelf area of the Permian Basin in Terry County, Texas. The prospect was defined with a 14-square mile seismic survey and resulted in the leasing of approximately 3,640 acres. In 1996, two exploratory wells were drilled in this project at a cost to Midland of approximately $660,000, with one completed in the Clearfork area. Average daily production from this well in 1997 was 11 BOE. Neither of these wells produced in economic quantities and in April 1998, Midland sold most of its interest in this project for $200,000 and retained a 6.875% working interest with Midland's share of the cost of drilling the next well being paid by the purchaser. Lakota 3-D Seismic Exploration and Development Project The Lakota project was acquired as a 3-D seismic exploration project in 1995 in the Northwest Shelf area of the Permian Basin in Terry County, Texas. The prospect was defined with a 14-square mile seismic survey and resulted in the leasing of approximately 2,480 acres. In 1997, one exploratory well was completed in this project as a Wolfcamp discovery at a cost to the company of $316,000. Midland owns a 30% working interest in this project. Average daily production from this well in 1997 was 14 BOE. Due to lack of economic success, no additional wells are currently planned in this project. Rhoda Walker (Cherry Canyon) Field This field is located in Ward County, Texas, in which Midland has an interest in nine wells which are operated by Midland with a combined average production rate in 1997 of approximately 100 BOPD and 143 MCFD, subject to normal declines. During the fourth quarter of 1995, three Rhoda Walker Field 65 69 development wells were drilled at a cost to Midland of approximately $880,000. These wells increased oil and gas production from this field by 140%. Midland owns a 100% working interest in this project. Ackerly (Dean) Field This field is located in Dawson County, Texas, in which Midland has an interest in two wells which are operated by Midland. These wells combined had a 1997 average production rate of approximately 41 BOPD and 20 MCFD gross production before royalty burdens. Midland owns a 100% working interest in this project. Jameson (Strawn) Field This field is located in Coke and Sterling Counties, Texas in which Midland has an interest in 58 active wells which are operated by Midland with a combined 1997 average production rate of approximately 120 BOPD and 1,500 MCFD. At the time Midland acquired the Jameson properties in 1992, there were 21 gross wells which were shut-in for various reasons by the former operator. Midland has returned 15 gross wells to production and has converted nearly 40% of the wells from producing via conventional pumping unit to a less expensive plunger lift method of artificial lift. In April and August 1996, Midland completed two field extension development wells at an aggregate cost of approximately $700,000. Average aggregate gross production rates in 1997 from these wells was approximately 45 BOPD and 250 MCFD. Effective June 1, 1996, Midland acquired various additional royalty interests in this field for approximately $500,000. Midland owns a 100% working interest in this project and net revenue interests on individual leases range from 90% to 92%. Cope Waterflood Unit and Advanced Reservoir Management Project The Cope Unit is located in Sterling County, Texas. This project encompasses 2,032 gross acres and at present has 21 gross active wells, seven of which are injectors. At the time Midland acquired the Cope Unit in 1990, production had declined to 100 BOPD. Several shut-in wells were reactivated with total unit production immediately improving to 137 BOPD. In early 1995, Midland began a joint project with the federal government's Los Alamos National Laboratory to develop computerized 3-D reservoir modeling and simulation of Midland-operated Cope Waterflood Unit. Completed in 1997, the simulation model is being utilized to improve reservoir management, potentially enhance oil production by locating bypassed oil, determining new infill drilling locations and designing optimum waterflood injection patterns for increased oil recovery. Effective May 1, 1996, Midland acquired an additional 15.75% working interest for approximately $79,000, and now owns approximately 77% of the working interest in this property. The Cope Unit produces from the Spraberry formation. In June 1996, Midland drilled a replacement well for one of the producing wells in the unit which was producing mostly water. The Cope Unit oil production has been maintained at approximately 125 barrels of oil per day and the unit's produced water has been reduced substantially. Other Properties In August 1994, Midland acquired working interests in certain oil and gas properties with 19 gross wells in Coke and Howard Counties, Texas, for $1,950,000, which was adjusted for revenues and expenses through the closing date. These wells are operated by Midland and in 1997 had a combined average production rate of approximately 62 BOPD and 215 MCFD, subject to normal declines. Midland owns a 100% working interest in these properties. In May 1995, Midland acquired a 50% working interest and operations in three State tracts in Redfish Bay Field, Nueces County, Texas in return for a commitment to expend $1,000,000 in capital expenditures over two years. In February 1997, Midland sold its interests in this field for $1,647,000. Midland realized a gain on this sale of approximately $349,000. 66 70 TEXAS GULF COAST Copano Bay 3-D Seismic Exploration and Development Project The Copano Bay property is located in Aransas County, Texas, approximately 50 miles northeast of Corpus Christi. The leasehold encompasses 2,355 gross acres and currently has eight gross producing wells. At the time Midland acquired Copano Bay in 1991, it was producing approximately 65 BOPD and 465 MCFD. Midland conducted several workovers, recompletions and re-entries, and increased production to average 52 BOPD and 828 MCFD in 1996 and 54 BOPD and 729 MCFD in 1997. During 1995, 1996 and 1997, Copano Bay properties accounted for approximately 9%, 5% and 6%, respectively, of Midland's total oil production and approximately 28%, 16% and 16%, respectively, of Midland's total gas production. Effective June 1, 1996, Midland acquired an additional 5% working interest in this property for approximately $177,000, and now owns approximately 68% of the working interest in this property. In 1997, a 3-D seismic survey was conducted covering a portion of Midland-owned acreage and, in the beginning of 1998, a second 3-D seismic survey was conducted covering the remainder of the acreage. Both seismic surveys were conducted at no cost to Midland and the survey data is currently being processed. When processing is completed, Midland will be allowed to review the data to determine if any of the data is of any value to Midland. If Midland determines this data has any value, Midland will be allowed to purchase the data. In addition to the above described properties, Midland owns and operates 21 leases located within a 150-mile radius of Midland, Texas, containing 21 gross producing wells on 2,778 gross acres. These wells are produced from the Yates, Spraberry and Pennsylvanian formations at depths ranging from 1,800 feet to 9,000 feet. The production is heavily weighted to oil and some leases have additional development opportunities. Finding Cost. Midland's acquisition and finding cost for 1997 was $5.73 per BOE as compared to the 1996 and 1995 finding costs of $6.68 and $3.96 per BOE respectively. The average acquisition and finding cost for the three year period was $5.38 per BOE. Oil and Gas Mix. Midland's reserves were 53% oil and 47% gas at December 31, 1997 and its production mix was 54% oil and 46% gas during 1997. Drilling Activities. The following table sets forth the number of gross and net productive and dry wells in which Midland had an interest that were drilled and completed during the years ended December 31, 1997, 1996, and 1995. This information should not be considered indicative of future performance, nor should it be assumed that there is necessarily any correlation between the number of productive wells drilled and the oil and gas reserves generated thereby or the costs to Midland of productive wells compared with the costs of dry wells.

Oil and gas production from Midland's properties is marketed consistent with usual and customary industry practices which include the sale of oil at the wellhead to third parties and the sale of gas at the wellhead to third parties. Sales prices for both oil and gas production are negotiated based on factors normally considered in the industry such as the spot price for gas or the posted price for oil, distance from the well to the pipeline, well pressure, estimated reserves, quality of the gas or oil and prevailing supply conditions. During 1997, Midland had sales of oil and gas to marketed its natural gas and natural gas products to three purchasers that accounted for 10% or more of Midland's revenues. Those purchasers and their respective percentages were AMOCO Production Company (12%), Sun Refining Co. (15%), and Western Gas Resources (18%). Because there is a ready market for oil and gas, Midland is of the opinion that the loss of any one purchaser would not have an adverse effect on its ability to sell its oil and gas production. Hedging Activities. Midland engaged in no oil or gas commodity price hedging activities in 1997. Production, Price and Cost Data. The table below sets forth production, price and cost data with respect to Midland's properties for the years ended December 31, 1997, 1996 and 1995. These amounts are calculated without making pro forma adjustments for any acquisitions, divestitures or drilling activity that occurred during the respective years.

Office Property On July 11, 1995, Midland's office building located in Midland, Texas was sold to an unrelated third party and, in September 1995, Midland moved its executive offices to leased space located at 16701 Greenspoint Park Drive, Suite 200, Houston, Texas 77060. In November 1995, Midland purchased a 3,750 square foot building and 2.0 acres of land located at 3419 Hwy. 158, Midland, Texas, from a partnership of which Mr. Warley was a 50% owner, for use as a district office, warehouse and equipment yard. During 1997 Midland moved its executive offices to 616 F.M. 1960 West, Suite 600, Houston, Texas 77090, which it currently occupies under a lease expiring in 2002. The company also sold its district office and relocated in leased space in Midland, Texas. Contract Operating Agreement Effective as of June 1, 1998, Midland's wholly owned, operating subsidiary, MRO, and the Vista Operator, entered into a Contract Operating Agreement (herein so called) which provides, among other things, that the Operator will provide various contract operating services for and on behalf of Midland's oil and gas properties through October 31, 1998 and on a month-to-month basis thereafter unless otherwise terminated by either party upon 30 days' prior written notice. For a more detailed description of such agreement, see "The Merger -- Other Agreements" and "Certain Transactions." Competition and Markets Competition. The oil and gas industry is highly competitive. A large number of companies and individuals engage in the exploration for and development of oil and gas properties, and there is a high degree of competition for oil and gas properties suitable for development or exploration. Acquisitions of oil and gas properties have been an important element of Midland's growth. The principal competitive factors in the acquisition of oil and gas properties include the staff and data necessary to identify, investigate and purchase 69 73 such properties and the financial resources necessary to acquire and develop them. Many of Midland's competitors are substantially larger and have greater financial and other resources than Midland. Markets. Midland's ability to produce and market oil and gas profitably depends on numerous factors beyond Midland's control. The effect of these factors cannot be accurately predicted or anticipated. In recent years, worldwide oil production capacity and gas production capacity in certain areas of the United States have exceeded demand, with resulting declines in the price of oil and gas. Although Midland cannot predict the occurrence of events that may affect oil and gas prices or the degree to which oil and gas prices will be affected, it is possible that prices for any oil or gas that Midland produces will be lower than those currently available. Any significant decline in the price of oil or gas would adversely affect Midland's revenues, profitability and cash flow and could, under certain circumstances, result in a reduction in the carrying value of Midland's oil and gas properties. Governmental Regulation Midland's oil and gas exploration, production and marketing activities are subject to extensive laws, rules and regulations promulgated by federal and state legislatures and agencies. Failure to comply with such laws, rules and regulations can result in substantial penalties. The legislative and regulatory burden on the oil and gas industry increases Midland's cost of doing business and affects its profitability. Although Midland believes it is in substantial compliance with all applicable laws and regulations, because those laws and regulations are frequently amended, interpreted and reinterpreted, Midland is unable to predict the future cost or impact of complying with such laws and regulations. The State of Texas and many other states require permits for drilling operations, drilling bonds and reports concerning operations and impose other requirements relating to the exploration and production of oil and gas. These states also have statutes or regulations addressing conservation matters, including provisions for the unitization or pooling of oil and gas properties, the establishment of maximum rates of production from wells and the regulation of spacing, plugging and abandonment of such wells. The Federal Energy Regulatory Commission ("FERC") regulates interstate gas transportation rates and service conditions, which affect the marketing of gas produced by Midland, as well as the revenues received by Midland for sales of such production. Since the mid-1980s, FERC has issued a series of orders, culminating in Order Nos. 636, 636-A, 636-B and 636-C ("Order 636"), that have significantly altered the marketing and transportation of gas. Order 636 mandates a fundamental restructuring of interstate pipeline sales and transportation service, including the unbundling by interstate pipelines of the sale, transportation, storage and other components of the city-gate sales services such pipelines previously performed and the provision of open-access transportation on a nondiscriminatory basis. One of FERC's purposes in issuing the order was to increase competition within all phases of the gas industry. Numerous parties have filed petitions for review of Order 636, as well as orders in individual pipeline restructuring proceedings. In July 1996, Order 636 was generally upheld on appeal, and the portions remanded for further action do not appear to materially affect Midland. Because Order 636 may be modified as a result of the appeals, it is difficult to predict the ultimate impact of the orders on Midland and its gas marketing efforts. Generally, Order 636 has eliminated or substantially reduced the interstate pipelines' traditional role as wholesalers of gas and has substantially increased competition and volatility in gas markets. The FERC frequently reexamines its transportation-related policies, including the terms and conditions under which interstate pipeline shippers may release interstate pipeline capacity for resale in the secondary market, the appropriateness of the use of negotiated and market-based rates, and the implementation of additional standardized terms and conditions for interstate gas transmission. In April 1998, the FERC issued a new rule to further standardize pipeline transportation tariffs that could adversely affect the reliability of scheduled interruptible transportation service on some pipelines. While any resulting FERC action would affect Midland only indirectly, any new rules and policy statements may have the effect of enhancing competition in gas markets or affecting the cost or availability of pipeline transportation. The price Midland receives from the sale of oil and gas is affected by the cost of transporting products to markets. Effective January 1, 1995, FERC implemented regulations establishing an indexing system for 70 74 transportation rates for oil pipelines, which, generally, would index such rates to inflation, subject to certain conditions and limitations. Midland is not able to predict with certainty the effect, if any, of these regulations on its operations. However, the regulations may increase transportation costs or reduce well head prices for oil and gas. See "Risk Factors -- Governmental Regulation and Environmental Matters." Environmental Matters Midland's operations and properties are, like the oil and gas industry in general, subject to extensive and changing federal, state and local laws and regulations relating to environmental protection, including the generation, storage, handling, emission, transportation and discharge of materials into the environment, and relating to safety and health. The recent trend in environmental legislation and regulation generally is toward stricter standards, and this trend will likely continue. These laws and regulations may require the acquisition of a permit or other authorization before construction or drilling commences and for certain other activities; limit or prohibit construction, drilling and other activities on certain lands lying within wilderness and other protected areas; and impose substantial liabilities for pollution resulting from Midland's operations. The permits required for various of Midland's operations are subject to revocation, modification and renewal by issuing authorities. Governmental authorities have the power to enforce compliance with their regulations, and violations are subject to fines or injunction, or both. In the opinion of management, Midland is in substantial compliance with current applicable environmental laws and regulations, and Midland has no material commitments for capital expenditures to comply with existing environmental requirements. Nevertheless, changes in existing environmental laws and regulations or in interpretations thereof could have a significant impact on Midland, as well as the oil and gas industry in general. The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA") and comparable state statutes impose strict and arguably joint and several liability on owners and operators of certain sites and on persons who dispose of or arranged for the disposal of "hazardous substances" found at such sites. Under CERCLA, such persons may be subject to liability for the costs of cleaning up the hazardous substances, for damages to natural resources and for the costs of certain health studies. Furthermore, it is not uncommon for the neighboring land owners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances related 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 fines and penalties for noncompliance. Although CERCLA currently excludes petroleum from its definition of "hazardous substance," state laws affecting Midland's operations impose clean-up liability relating to petroleum and petroleum related products. In addition, although RCRA classifies certain oil field wastes as "non-hazardous," such exploration and production wastes could be reclassified as hazardous wastes thereby making such wastes subject to more stringent handling, disposal and cleanup requirements. Federal regulations require certain owners or operators of facilities that store or otherwise handle oil, such as Midland, to prepare and implement spill prevention, control countermeasure and response plans relating to the possible discharge of oil into surface waters. The Oil Pollution Act of 1990, as amended ("OPA"), contains numerous requirements relating to the prevention of and response to oil spills into waters of the United States. For onshore and offshore facilities that may affect waters of the United States, the OPA requires an operator to demonstrate financial responsibility. Regulations are currently being developed under federal and state laws concerning oil pollution prevention and other matters that may impose additional regulatory burdens on Midland. In addition, the Clean Water Act and analogous state laws require permits to be obtained to authorize discharge into surface waters or to construct facilities in wetland areas. With respect to certain of its operations, Midland is required to maintain such permits or meet general permit requirements. The Environmental Pollution Agency ("EPA") recently adopted regulations concerning discharges of storm water runoff. This program requires covered facilities to obtain individual permits, participate in a group or seek coverage under an EPA general permit. Midland believes that it will be able to obtain, or be included under, such permits, where necessary, and to make minor modifications to existing facilities and operations that would not have a material effect on Midland. 71 75 Midland has acquired leasehold interests in numerous properties that for many years have produced oil and gas. Although the previous owners of these interests have used operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties. In addition, some of Midland's properties are operated by third parties over whom Midland has no control. Notwithstanding Midland's lack of control over properties operated by others, the failure of the operator to comply with applicable environmental regulations may, in certain circumstances, adversely impact Midland. See "Risk Factors -- Governmental Regulation and Environmental Matters." Employees On September 11, 1998, Midland had 8 full-time employees, none of which are subject to collective bargaining arrangements. From time to time, Midland utilizes the services of independent contractors to perform various field and administrative services. Experienced personnel are available in all disciplines should the need to hire additional staff arise. Litigation Midland is a defendant in a lawsuit filed on July 31, 1995, which is currently pending in the 238th Judicial District Court of Midland County, Texas, styled Manna Oil & Gas, Inc., Dobbs Oil & Gas, Inc. v. Midland Resources, Inc., Miresco, Inc. Midland Resources Operating Company, Inc., Cause No. 40,677. The case involves certain Gulf Coast properties located in Copano Bay wherein Midland owns a 68% working interest and is the operator of the properties. The plaintiffs (1) seek a declarative judgment that Midland has failed to meet the standards and procedures set out in the Operating Agreement; (2) are attempting to recover approximately $230,000; (3) seek an accounting for the years 1993-1995; and (4) seek attorney fees and costs. Midland believes it has a defensible position with respect to all of the Plaintiffs' claims and intends to defend this case very aggressively. Midland filed a counterclaim against Manna Oil and Gas, Inc. ("Manna") in which Midland is seeking specific performance of an oral contract that Midland entered into with Manna, whereby Midland and Manna agreed that if either party acquired any additional property interest or contract rights of any kind in the properties that are the subject of the underlying lawsuit that said party would offer to convey to the other party their proportionate ownership in such newly acquired property interest or contract rights. In the alternative, Midland claims that Manna breached such contract, and Midland is seeking monetary damages, resulting from said breach of contract, as well as attorney fees and court costs. Management believes that the ultimate resolution of this matter will not have a material adverse effect on Midland.

(2) The Vista Partnership believes that EBITDAEX may provide additional information about the Vista Partnership's discretionary cash flow and its ability to meet its future requirements for debt service, capital expenditures and working capital. EBITDAEX is a financial measure commonly used in the oil and gas industry and should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating activities or any other measures of financial performance presented in accordance with generally accepted accounting principles or as a measure of a company's profitability or 78 82 liquidity. Because EBITDAEX excludes some, but not all, items that affect net income and these measures may vary among companies, the EBITDAEX data presented above may not be comparable to similarly titled measures of other companies. EBITDAEX (as used herein) is calculated by adding depletion, depreciation and amortization, and exploration costs to operating income. Exploration costs represent discretionary cost items. Therefore, exploration costs have been added back in order to present a discretionary cash flow for the Vista Partnership. Interest includes accrued interest expense and amortization of deferred financing costs. (3) For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as income (loss) before taxes plus fixed charges. Fixed charges consist of interest expense. For the six months ended June 30, 1998, earnings were insufficient to cover fixed charges by $0.5 million. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF THE VISTA PARTNERSHIP General Financial Performance For the Six Months Ended June 30, 1998. The Vista Partnership reported a net loss of $340,000 for the first six months of 1998 as compared to a net loss of $70,000 for the same period in 1997. Average daily oil production increased 39% to 1,303 Bbls per day for the first six months of 1998 from 939 Bbls per day for the same period of 1997, and average daily gas production increased 81% to 2,641 Mcf per day from 1,458 Mcf per day for the same period. As discussed more fully in "-- Results of Operations" below, the Vista Partnership's financial performance for the first six months of 1998 was negatively impacted by the following items: (i) dramatically lower (27%) oil prices and lower (4%) gas prices received; (ii) increase in gross production costs due to the addition of properties as a result of the E.G. Acquisition (as defined below) made during the third quarter of 1997; (iii) an increase in interest expense as a result of the additional indebtedness incurred in respect of the E.G. Acquisition; and (iv) an increase in depletion expense attributable to the additional properties acquired in the E.G. Acquisition. Net cash provided by operating activities decreased 63% to $626,000 for the first six months of 1998 as compared to $1,678,000 for the same period in 1997. This decrease was primarily attributable to significantly lower commodity prices for oil and gas and increased production costs and interest expense as a result of the additional indebtedness incurred in respect of the E.G. Acquisition. The Vista Partnership strives to maintain its outstanding indebtedness at a moderate level in order to provide sufficient financial flexibility to fund future opportunities. The Vista Partnership's total book capitalization at June 30, 1998 was $25.8 million, consisting of total long-term debt of $18.4 million and partners' equity of $7.4 million. Debt as a percentage of total book capitalization was 71% at June 30, 1998, which was essentially the same as at December 31, 1997. The Vista Partnership's debt level is currently high due to significant borrowings under its bank credit facility for its 1997 acquisitions and certain drilling and exploitation projects. As the Vista Partnership's borrowing base under its bank credit facility has grown due to the success of its acquisition and exploitation efforts, the Vista Partnership has been able to fund all of its acquisitions and its drilling and exploitation programs from borrowings under its bank credit facility and cash flow from operations without raising additional equity capital. Financial Performance For the Year Ended December 31, 1997. The Vista Partnership reported net income of $597,681 (inclusive of a $315,518 non-cash, non-operating charge for amortization of employee unit option awards) for the year ended December 31, 1997 as compared to net income of $394,282 for the year ended December 31, 1996. The Vista Partnership's net income for the year ended December 31, 1997 was positively impacted by the following items: (i) significantly increased oil and gas revenue attributable to increased production resulting from the success of the Vista Partnership's drilling program and the addition of a significant group of properties acquired in the E.G. Acquisition in the third quarter of 1997; and (ii) a decrease in exploration expenses due to fewer write offs of expired acreage and less dry hole expenses. Net cash provided by operating activities increased 67% to $3.5 million for the year ended December 31, 1997 as compared to $2.1 million for the year ended December 31, 1996. This increase was primarily attributable to (i) significantly increased oil and gas revenue attributable to increased production resulting 79 83 from the success of the Vista Partnership's drilling program and the addition of a significant group of properties acquired in the E.G. Acquisition in the third quarter of 1997; and (ii) the decrease in exploration expenses due to fewer write offs of expired acreage and less dry hole expenses. Long-term debt increased by $9.3 million to $17.9 million at December 31, 1997 from $8.6 million at December 31, 1996 principally due to borrowings made in connection with each of the acquisitions made by the Vista Partnership in 1997 (approximately $7.4 million) and to fund that portion of the Vista Partnership's capital budget for drilling and exploitation projects that was not funded from cash flow (approximately $1.9 million). Consequently, the Vista Partnership's long-term debt to total book capitalization increased to an historically high level of 70% at December 31, 1997 from 56% at December 31, 1996. Significant Activities During the Six Months Ended June 30, 1998 Drilling Activities. During 1998, the Vista Partnership has continued its emphasis on development, exploration and production activities, with a primary focus on the exploitation of its current portfolio of drilling locations. This portfolio was significantly enhanced and expanded by the major acquisitions completed in 1995, 1996 and 1997 and the Vista Partnership's 1997 drilling program. These activities have added a significant number of new locations and opportunities to which new proved undeveloped reserves have been assigned. The Vista Partnership believes that its current portfolio of undeveloped prospects and projects provides attractive development and exploration opportunities for at least the next two to four years. Of the total 1998 capital expenditure drilling budget of $5.8 million, the Vista Partnership has allocated $4.9 million to exploitation and development activities and $900,000 to exploration activities. The Vista Partnership does not budget for oil and gas property acquisitions as they are made on a case by case basis as opportunities arise. This capital expenditure drilling budget reflects the Vista Partnership's plans to drill approximately 16 oil and gas wells in 1998. The Vista Partnership currently expects to fund its 1998 capital expenditure budget primarily with internally generated cash flow, borrowings under its bank credit facility and proceeds from the sale of non-strategic assets. During the first six months of 1998, the Vista Partnership participated in the drilling and completion of seven gross development wells and no exploration wells. None of these wells were in progress at December 31, 1997. Of the total wells completed during the six months ended June 30, 1998, all seven were completed successfully which resulted in a 100% success rate. No wells were drilling at June 30, 1998. Acquisition Activities. Although various acquisition candidates were evaluated during the first six months of 1998, no material acquisitions were made during such time period. Significant Activities During 1997 Drilling Activities. The Vista Partnership continues to realize the benefits of its focused activities in the development and exploitation of its existing core areas. The Vista Partnership devotes significant efforts to exploitation and exploration of its existing property base and believes that substantial additional opportunities remain. During 1997, the Vista Partnership participated in the drilling and completion of 23 gross exploration and development wells (20 of which were operated by the Vista Partnership). The Vista Partnership's total capital expenditures during 1997 for exploration and development activities were $4.7 million. Acquisition Activities. In addition to acquiring various additional small working interests and overriding royalty interests in properties already owned and operated by the Vista Partnership (total purchase prices of about $200,000), the Vista Partnership closed two significant producing property acquisitions in 1997. In May 1997, the Vista Partnership acquired all of the interests of Coastal Oil and Gas Corporation in three producing leases located in Howard Glasscock Field, Howard County, Texas, for a net purchase price of $1.1 million (the "Coastal Acquisition"). The interests acquired were attributable to leases already owned and operated by the Vista Partnership. Effective as of July 1, 1997, the Vista Partnership acquired substantially all of the producing oil and gas properties (representing working interests ranging from 25% to 100% in approximately 44 wells located in West Texas, South Texas, and Southeastern New Mexico) from E. G. Operating, a division of FGL, Inc. for a net purchase price of $6.1 million (the "E.G. Acquisition"). All of the 80 84 Vista Partnership's 1997 acquisitions were funded through a combination of cash on hand and proceeds from long-term borrowings under its bank credit facility. Asset Dispositions. From time to time, the Vista Partnership disposes of non-strategic assets in order to raise capital for other activities, reduce indebtedness or eliminate costs associated with non-strategic assets. During 1997, the Vista Partnership sold certain non-strategic assets for a total net consideration of $390,000, which resulted in a book loss of $87,678. Proved Reserves. The Vista Partnership's proved reserves totaled 9.1 million BOE at December 31, 1997, 5.7 million BOE at December 31, 1996, and 3.0 million BOE at December 31, 1995. Total proved reserves increased 59% in 1997 and 90% in 1996. Oil reserves at year end 1997 were 7.2 million Bbls compared to 4.5 million Bbls at year end 1996 and 2.2 million Bbls at year end 1995 (a 60% increase from 1996 to 1997 and a 200% increase from 1995 to 1996). Natural gas reserves at year end 1997 were 11.3 Bcf compared to 7.2 Bcf at year end 1996 and 4.8 Bcf at year end 1995 (a 57% increase from 1996 to 1997 and a 50% increase from 1995 to 1996). Reserve Replacement. For three years, since inception of the company, the Vista Partnership has been able to more than replace its annual production volumes with proved reserves of crude oil and natural gas. During 1997 Vista added 3,895 MBOE of reserves resulting in reserve replacement of 728% of annual production. The reserve replacement rate in 1996 was 919%. Of the 3,895 MBOE of reserves added in 1997, 1,675 MBOE was added through drilling, remedial work and secondary recovery projects, 1,788 MBOE was added through acquisitions of proved reserves, and 432 MBOE was added as a result of revisions. Reserve revisions are a result of either changes in current estimates of reserves or changes in estimates of reserves that are economical to produce given the current pricing conditions. The Vista Partnership's reserves as of December 31, 1997 were estimated using a price of $16.10 per Bbl and $2.01 per Mcf. Should prices either rise or decline in future years, reserves may be revised either upward or downward for quantities which may or may not be economical to produce. Finding Cost. The Vista Partnership's acquisition and finding cost for 1997 was $3.17 per BOE as compared to the 1996 and 1995 finding costs of $2.55 and $2.90 per BOE, respectively. The average acquisition and finding cost for the three-year period was $2.90 per BOE. Cost Reductions. Production costs (being lease operating expenses and production taxes) per BOE declined 3.9% (from $7.18 to $6.90) for the year ended December 31, 1997, as compared to the year ended December 31, 1996. This decline is a result of the Vista Partnership's continued emphasis on cost control efforts and the disposition of certain high-cost, non-strategic oil and gas properties during 1997. The Vista Partnership expects production costs per BOE to continue to decline as further cost reductions are implemented and additional high-cost, non-strategic properties are sold. Commodity Prices and Hedging Activities. The Vista Partnership was negatively impacted by slightly lower oil and gas prices during 1997. In 1997, the Vista Partnership received an average oil price of $17.63 per Bbl and an average gas price of $2.22 per Mcf, representing a decrease of 2% for oil and a slight increase for gas, respectively, from 1996. The oil and gas prices that the Vista Partnership reports is based on the actual prices received for the commodities adjusted by the results of the Vista Partnership's hedging activities. The Vista Partnership periodically enters into commodity derivative contracts (i.e., swaps and collars) in order to (i) reduce the effect of the volatility of price changes on the commodities the Vista Partnership produces and sells, (ii) support the Vista Partnership's annual capital budgeting and expenditure plans, and (iii) lock in prices to protect the economics related to certain capital projects. During 1997, the Vista Partnership's hedging activities reduced the average price received for oil by 3%. The Vista Partnership engaged in no gas hedging activities in 1997. Capitalization. The Vista Partnership strives to maintain its outstanding indebtedness at a moderate level in order to provide sufficient financial flexibility for future opportunities. The Vista Partnership's total book capitalization at December 31, 1997, was $25.6 million, consisting of total long-term debt of $17.9 million and partners' equity of $7.7 million. Debt as a percentage of total capitalization was 70% at December 31, 1997, up from 56% at December 31, 1996. This increase is primarily due to borrowings made in 81 85 connection with each of the acquisitions made by the Vista Partnership in 1997 (approximately $7.4 million) and to fund that portion of the Vista Partnership's capital budget for drilling and exploitation projects that was not funded from cash flow (approximately $1.9 million). Legal Actions. The only legal matter in which the Vista Partnership is or has been involved concerns the bankruptcy of a drilling contractor engaged by the Vista Partnership to drill several wells on a turnkey basis in late 1996. The Vista Partnership still holds $208,060 owed under the subject turnkey drilling contract. Claims have been made by various subcontract vendors for the monies held by the Vista Partnership. On November 11, 1997, a company claiming to own the invoices of the bankrupt drilling contractor through a factoring arrangement filed suit in state district court in Midland County seeking to collect the monies due under the subject turnkey drilling contract (the "Southwest Action"). Upon motion by the Vista Partnership, the district court on January 2, 1998, abated the legal action by the plaintiff pending the results of the bankruptcy proceedings and a determination as to which, if any, claimants including the plaintiff are entitled to the monies held by the Vista Partnership. The Vista Partnership carries the entire $208,060 as an account payable on its balance sheet. RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997 Oil and Gas Production. SIX MONTHS ENDED JUNE 30, ----------------------- 1998 1997 ---------- ---------- Revenues.................................................... $4,057,279 $3,633,274 Costs and expenses: Production costs.......................................... 1,939,530 1,672,260 Depletion................................................. 962,026 932,192 Exploration costs......................................... -- 58,600 ---------- ---------- 2,901,556 2,663,052 ---------- ---------- Operating profit (excluding general and administrative expenses and income taxes)............................. $1,155,723 $ 970,222 ========== ========== Production: Oil (Bbls)................................................ 235,773 169,975 Gas (Mcf)................................................. 477,990 263,929 Total (BOE)....................................... 315,438 213,963 Average Daily Production: Oil (Bbls)................................................ 1,303 939 Gas (Mcf)................................................. 2,641 1,458 ---------- ---------- Total (BOE)....................................... 1,743 1,182 Average Oil Price (Per Bbl)................................. $ 13.28 $ 18.22 Average Gas Price (Per Mcf)................................. $ 1.92 $ 2.01 Costs (Per BOE): Lease operating expense................................... $ 5.10 $ 6.52 Production taxes.......................................... $ 1.05 $ 1.29 ---------- ---------- Total production costs............................ $ 6.15 $ 7.81 Depletion................................................. $ 3.05 $ 4.36 Oil and Gas Revenues. Revenues from oil and gas operations totaled $4.0 million in the first six months of 1998 compared to $3.6 million in the first six months of 1997, representing an increase of 11%. The increase is primarily attributable to significant increases in production due to the Vista Partnership's successful acquisition and exploitation activities in 1997, offset by significantly decreased average prices being received for both oil and gas production. The average oil prices received for the six months ended June 30, 1998, decreased 27% (from $18.22 to $13.28 for the six months ended June 30, 1997 and 1998, respectively), while 82 86 the average gas price received decreased 4% (from $2.01 to $1.92 for the six months ended June 30, 1997 and 1998, respectively). Average daily oil production increased 39% from 939 Bbls for the first six months of 1997 to 1,303 Bbls for the same period of 1998, and average daily gas production increased 81% from 1,458 Mcf to 2,641 Mcf for the same period. Approximately 62% of period to period increases in oil and gas production is attributable to properties acquired in acquisitions and 38% is attributable to existing properties. Hedging Activities. The oil and gas prices that the Vista Partnership reports is based on the actual prices received for the commodities adjusted for the results of any of the Vista Partnership's hedging activities. The Vista Partnership periodically enters into commodity derivative contracts (i.e., swaps and collars) in order to (i) reduce the effect of the volatility of price changes on the commodities the Vista Partnership produces and sells, (ii) support the Vista Partnership's annual capital budgeting and expenditure plans, and (iii) lock in prices to protect the economics related to certain capital projects. Set forth below is the contract amount and material terms of all crude oil hedging instruments held by the Vista Partnership at June 30, 1998 (monthly volumes are expressed in Bbls and all prices are expressed in the calendar monthly average of daily NYMEX closing prices for Light Sweet Crude Oil): TRADE TYPE MONTHLY PUT CALL DATE TRANSACTION VOLUME FLOOR PRICE CEILING PRICE TERM - -------- ----------- ------- ------------ ------------- ------------------ 12-15-97 Collar 10,000 $ 18.00 Bbl $ 19.805 Bbl 4-1-98 to 12-31-98 12-15-97 Collar 10,000 $ 18.50 Bbl $ 19.280 Bbl 4-1-98 to 3-31-99 Set forth below is the contract amount and material terms of all NYMEX natural gas hedging instruments held by the Vista Partnership at June 30, 1998 (monthly volumes are expressed in MMBtus and prices are expressed in the monthly NYMEX (Henry Heb) closing price for natural gas): TRADE TYPE MONTHLY PUT CALL DATE TRANSACTION VOLUME FLOOR PRICE CEILING PRICE TERM - -------- ----------- ------- ------------ ------------- ------------------ 4-5-98 Collar 80,000 $2.20 MMBtu $2.49 MMBtu 4-1-98 to 9-30-98 Set forth below is the contract amount and material terms of each natural gas basis swap held by the Vista Partnership at June 30, 1998 (monthly volumes are expressed in MMBtus): TRADE TYPE MONTHLY DATE TRANSACTION VOLUME SWAP PRICE TERM - -------- ----------- ------- ---------- ------------------ 4-5-98 Basis swap 40,000 Houston Ship Channel (NYMEX 4-1-98 to 9-30-98 (Henry Hub) minus $0.0275 MMBtu) 4-5-98 Basis swap 40,000 Permian Basis (El Paso) 4-1-98 to 9-30-98 (NYMEX (Henry Hub) minus $0.20 MMBtu) Production Costs. Total production costs (inclusive of all lease operating expenses and production taxes) per BOE decreased 21% to $6.15 during the six months ended June 30, 1998, as compared to production costs per BOE of $7.81 during the same period of 1997. These reductions are primarily due to the Vista Partnership's continued and concentrated efforts to evaluate and reduce all operating costs, the addition of higher margin properties acquired by Vista in the E.G. Acquisition, and the sale of certain high operating cost properties during 1997. Exploration Costs. Exploration costs (which includes abandonments, dry hole costs, geological and geophysical costs) decreased to $0 during the first six months of 1998 from $63,856 during the same period in 1997 because the Vista Partnership did not incur any dry hole costs or expired acreage costs in the first six months of 1998. General and Administrative Expense. General and administrative expense was $620,665 for the six months ended June 30, 1998, as compared to $475,640 for the six months ended June 30, 1997, 83 87 representing a 30% increase. Such increase was primarily due to the costs associated with the hiring of additional employees in 1997 as the Vista Partnership's business has grown. Amortization of Unit Option Awards. The amortization of unit option awards was $192,177 for the six months ended June 30, 1998, as compared to $264,594 for the six months ended June 30, 1997. Vista estimates the compensation associated with the option awards based on estimated fair value less exercise price. Estimated compensation expense is recorded over the vesting period and will be adjusted prospectively as the estimated fair value of the options changes. Interest Expense. Interest expense for the six months ended June 30, 1998 increased to $713,961 as compared to $394,169 for the comparable period in 1997, representing an 81% increase. This increase is primarily due to additional borrowings made in connection with each of the acquisitions made by the Vista Partnership in 1997 (approximately $7.4 million) and to fund that portion of the Vista Partnership's capital budget for drilling and exploitation projects that was not funded from cash flow (approximately $1.9 million). Depletion, Depreciation and Amortization Expense. Depletion expense per BOE declined to $3.05 during the first six months of 1998 from $4.36 per BOE during the same period of 1997. The decrease in depletion expense per BOE during 1998 is primarily related to increases in oil and gas reserves on certain properties which resulted in slightly lower depletion rates for such properties. Income Taxes. Since the Vista Partnership's legal structure is that of a limited partnership, it records no federal income taxes as these taxes are the responsibility of the individual partners. 84 88 RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996, AND FOR THE PERIOD FROM INCEPTION (SEPTEMBER 21, 1995) TO DECEMBER 31, 1995 Oil and Gas Production. 1997 1996 1995 ----------- ----------- ----------- Revenues................................... $ 8,874,961 $ 5,537,720 $ 1,348,647 Costs and expenses: Production costs......................... 3,688,695 2,544,567 728,540 Depletion................................ 2,169,098 1,272,316 308,132 Exploration costs........................ 97,211 273,843 -- ----------- ----------- ----------- 5,955,004 4,090,726 1,036,672 ----------- ----------- ----------- Operating profit (excluding general and administrative expenses and income taxes)................................ $ 2,919,957 $ 1,446,994 $ 311,975 =========== =========== =========== Production: Oil (Bbls)............................... 403,812 253,321 68,211 Gas (Mcf)................................ 784,298 458,278 156,515 Total (BOE)...................... 534,528 329,701 94,297 Average Daily Production: Oil (Bbls)............................... 1,107 693 444 Gas (Mcf)................................ 2,148 1,255 1,020 ----------- ----------- ----------- Total (BOE)...................... 1,465 902 614 Average Oil Price (Per Bbl)................ $ 17.63 $ 18.04 $ 15.70 Average Gas Price (Per Mcf)................ $ 2.22 $ 2.19 $ 1.75 Costs (Per BOE): Lease operating expense.................. $ 5.62 $ 6.35 $ 6.12 Production taxes......................... $ 1.28 $ 1.37 $ 1.61 ----------- ----------- ----------- Total production costs........... $ 6.90 $ 7.72 $ 7.73 Depletion................................ $ 4.06 $ 3.86 $ 3.27 Oil and Gas Revenues. Revenues from oil and gas operations totaled $8.9 million in 1997, $5.5 million in 1996 and $1.3 million in 1995, representing a 60% increase from 1996 to 1997 and a 310% increase from 1995 to 1996. The increase from 1996 to 1997 is primarily attributable to significant increases in production due to the Vista Partnership's successful acquisition and exploitation activities in 1996 and 1997, offset by significantly decreased average prices being received for oil production. Due to the Vista Partnership's formation in September 1995, 1995 production consists of a short year. Accordingly, the increase from 1995 to 1996 is primarily due to 1996 being a full year of production and, to a lesser extent, additional oil and gas sales resulting from successful acquisition and drilling activities in 1996. The average oil prices received for the year ended December 31, 1997 decreased 2% (from $18.04 in 1996 to $17.63 in 1997), while the average gas price received increased slightly (from $2.19 in 1996 to $2.22 in 1997). The average oil prices received for the year ended December 31, 1996 increased 15% (from $15.70 in 1995 to $18.04 in 1996), while the average gas price received increased 25% (from $1.75 in 1995 to $2.19 in 1996). Average daily oil production increased 60% from 693 Bbls for the year ended December 31, 1996 to 1107 Bbls for the year ended December 31, 1997, and average daily gas production increased 71% from 1255 Mcf to 2148 Mcf for the same period. Such increases from 1996 to 1997 are attributable approximately 70% to properties acquired in acquisitions and 30% to existing properties. Average daily oil production increased 56% from 444 Bbls for the year ended December 31, 1995 to 693 Bbls for the year ended December 31, 1996, and average daily gas production increased 23% from 1020 Mcf to 1255 Mcf for the same period. Such increases from 1995 to 1996 are attributable approximately 72% to properties acquired in acquisitions and 28% to existing properties. Hedging Activities. From time to time, the Vista Partnership has utilized hedging transactions with respect to a portion of its oil and gas production to achieve a more predictable cash flow, as well as to reduce 85 89 its exposure to price fluctuations. While the use of these hedging arrangements limits the downside risk of price declines, such use may also limit any benefits which may be derived from price increases. The oil and gas prices that the Vista Partnership reports are based on the actual prices received for the commodities adjusted for the results of any Vista Partnership hedging activities. The Vista Partnership uses various financial instruments, such as swaps and collars, whereby monthly settlements are based on differences between the prices specified in the instruments and the settlement prices of certain futures contracts quoted on the NYMEX or certain other indices. Generally, when the applicable settlement price is less than the price specified in the contract, the Vista Partnership receives a settlement from the counterparty based on the difference. Similarly, when the applicable settlement price is higher than the specified price, the Vista Partnership pays the counterparty based on the difference. The instruments utilized by the Vista Partnership differ from futures contracts in that there is not a contractual obligation which requires or allows for the future physical delivery of the hedged products. The Vista Partnership has entered into collar arrangements for 90,000 barrels of crude oil production for the period from April 1998 through December 1998 at a floor price of $18.00 per Bbl and a ceiling price of $19.805 per Bbl. In addition, the Vista Partnership has hedged 120,000 barrels of oil production from April 1998 through March 1999 under collar arrangements with a floor price of $18.50 per Bbl and a ceiling price of $19.280 per Bbl. The Vista Partnership has entered into a collar arrangement for 480,000 MMbtu of natural gas from April 1998 through September 1998 at a floor price of $2.20 per MMBtu and a ceiling price of $2.49 per MMBtu. The Vista Partnership also has in place two basis swaps for the same April 1998 through September 1998 time period. The two basis swaps are: (i) Houston Ship Channel Basis for 40,000 MMBtu per month at a fixed price of NYMEX Henry Hub minus $0.0275 per MMBtu; and (ii) Permian Basin (El Paso) Basis for 40,000 MMBtu per month at a fixed price of NYMEX Henry Hub minus $0.20 per MMBtu. Production Costs. Total production costs per BOE decreased 11% (from $7.72 in 1996 to $6.90 in 1997). This significant reduction is primarily due to the Vista Partnership's continued and concentrated efforts to evaluate and reduce all operating costs, the addition of higher margin properties acquired in the E.G. Acquisition, and the sale of certain high operating cost properties. Total production costs per BOE remained flat in 1996 as compared to 1995 (from $7.73 in 1995 to $7.72 in 1996). Exploration Costs. Exploration costs (which include abandonments, dry hole costs and geological and geophysical costs) have not historically been a material cost to the Vista Partnership. Such costs were $97,211, $273,843 and $0 in 1997, 1996 and 1995, respectively. General and Administrative Expenses. General and administrative expense increased 70% in 1997 (from $581,048 in 1996 to $987,020 in 1997). Such increase was primarily due to the costs associated with the hiring of additional employees in 1997 as the Vista Partnership's business has grown. General administrative expenses per BOE were $1.85, $1.76, and $2.21 in 1997, 1996 and 1995 respectively. Amortization of Unit Option Awards. The amortization of unit option awards was $315,518, 0 and 0 in 1997, 1996 and 1995, respectively. Estimated compensation expense changes as the estimated fair value of the options change. The estimated compensation expense is recognized over the vesting period. Interest Expense. Interest expense totaled $1,048,009, in 1997, $476,363 in 1996 and $77,093 in 1995, representing a 120% increase from 1996 to 1997 and a 518% increase from 1995 to 1996. These increases are a result of increased borrowings under the Vista Partnership's bank credit facility. As the Vista Partnership's borrowing base under its bank credit facility has grown due to the success of its acquisition and exploitation efforts, the Vista Partnership has been able to fund all of its acquisitions and its drilling and exploitation programs from borrowings under its bank credit facility and cash flow from operations without raising additional equity capital. Depletion, Depreciation and Amortization Expense. Depletion expense per BOE was $4.06 in 1997, $3.86 in 1996 and $3.27 in 1995, representing a 5% increase from 1996 to 1997 and a 18% increase from 1995 to 1996 These increases are primarily related to the addition of shorter life properties in the E.G. Acquisition. 86 90 Income Taxes. Since the Vista Partnership's legal structure is that of a limited partnership it records no federal income taxes as these taxes are the responsibility of the individual partners. Capital Commitments, Capital Resources and Liquidity Capital Commitments. The Vista Partnership's primary needs for cash are for acquisitions, development and exploration of oil and gas properties, repayment of principal and interest on outstanding indebtedness and working capital obligations. The Vista Partnership's cash expenditures during the first quarter of 1998 for additions to oil and gas properties totaled $659,782, all of which related to developmental drilling and exploitation activities. No acquisitions were made during the first quarter of 1998. The Vista Partnership's cash expenditures during 1997, 1996 and 1995 for additions to oil and gas properties (inclusive of producing property acquisitions) totaled $12.1 million, $6.7 million and $9.3 million, respectively. The 1997 amount includes $4.7 million for development and exploratory drilling, the majority of which was spent in the Permian Basin. The Vista Partnership's 1998 capital expenditure drilling budget is set at $5.8 million. Pursuant to this budget $4.9 million has been allocated to exploitation and development activities and $900,000 to exploration activities. The Vista Partnership does not budget for oil and gas property acquisitions as they are made on a case by case basis as opportunities arise. The 1998 budget reflects the Vista Partnership's plans to drill approximately 17 oil and gas wells in 1998. The Vista Partnership currently expects to fund its 1998 capital expenditure budget primarily with internally generated cash flow, borrowings under its bank credit facility and proceeds from the sale of non-strategic assets. Capital Resources. The Vista Partnership's primary capital resources are net cash provided by operating activities, borrowings under its bank credit facility and proceeds from the sale of non-strategic assets. Financing Activities. The Vista Partnership had $18.4 million outstanding under the Credit Facility at June 30, 1998, with a borrowing base thereunder of $22.3 million, leaving unused availability of $3.9 million. The weighted average interest rate for the six months ended June 30, 1998 on the Vista Partnership's indebtedness was 7.67% as compared to 8.20% for the six months ended June 30, 1997 (taking into account the effect of an interest rate swap). On August 15, 1997, the Vista Partnership entered into the Credit Facility, which has a current borrowing base of $22.3 million and an additional $1.0 million letter of credit facility. The Vista Partnership has two options with respect to interest rate elections on borrowings under the Credit Facility. The Vista Partnership may either elect an interest rate equal to the bank's prime rate plus 35 basis points or LIBOR plus 175 basis points (if amounts outstanding are greater than 50% of the then current borrowing base) or 150 basis points (if amounts outstanding are 50% or less of the then current borrowing base). The LIBOR-based option provides for one-, two-, three- or six-month periods. The weighted average interest rate for the year ended December 31, 1997 on the Vista Partnership's indebtedness was 7.76% as compared to 7.99% for the year ended December 31, 1996 and 7.95% for the year ended December 31, 1995. Liquidity. At June 30, 1998, the Vista Partnership had cash of $67,275 on hand compared to $527,129 at December 31, 1997 and $517,211 at December 31, 1996. The Vista Partnership's ratio of current assets to current liabilities was 1.19 at June 30, 1998, 1.13 at December 31, 1997 and 1.71 at December 31, 1996. Year 2000 Compliance. Vista does not expect that the cost of converting its computer system to Year 2000 compliance will be material to its financial condition. Vista believes it will be able to achieve Year 2000 compliance by the end of 1998 for an amount less than $10,000, and it does not currently anticipate any disruption in its operations as the result of any failure by Vista to be in compliance. Vista does not currently have any information concerning the Year 2000 compliance status of its customers and vendors. BUSINESS AND PROPERTIES OF THE VISTA PARTNERSHIP Business Description General. The Vista Partnership is a privately held independent oil and gas exploration and production company with operations and properties located in the Permian Basin of West Texas and Southeastern New 87 91 Mexico and the onshore Gulf Coast region of South Texas. The Vista Partnership and its operating subsidiary, Vista Resources, Inc., were formed by management of the Vista Partnership and various affiliates of NGP in September 1995 to focus on acquisitions and exploitation drilling primarily in the Permian Basin of West Texas and Southeast New Mexico. The Vista Partnership's main corporate objective is to rapidly expand reserve base, production capacity, cash flow and earnings in order to substantially grow the equity value of the company on a per unit of ownership basis. The Vista Partnership pursues its objectives through a program of acquisitions of producing oil and gas properties and the exploitation of such properties primarily through developmental and exploratory drilling coupled with a concentrated and continuous effort to reduce expenses on a BOE basis at all levels of its business. The Vista Partnership had approximately 9.1 million BOE of total proved reserves at December 31, 1997 and PV10 of approximately $38.6 million. Oil reserves at year end 1997 were 7.2 million Bbls and natural gas reserves at year end 1997 were 11.3 Bcf. On a BOE basis 52% of the Vista Partnership's total proved reserves at December 31, 1997 are proved developed reserves. The Vista Partnership operates 92% of its total proved reserves. The reserve-to-production ratio associated with the Vista Partnership's proved reserves is 14 years on a BOE basis. Financial Management. The Vista Partnership strives to maintain its outstanding indebtedness at a moderate level in order to provide financial flexibility for future acquisition, development and exploration opportunities. As with any growing organization, the Vista Partnership has experienced various levels of debt in recent years as it has responded to strategic opportunities. In 1997, the Vista Partnership's debt increased significantly due to borrowings made in connection with each of its acquisitions in 1997 ($7.4 million) and to fund that portion of its capital budget for drilling and exploitation projects that was not funded from cash flow ($1.9 million). Debt is currently 71% of total book capitalization. Nevertheless, management's objective of maintaining a flexible structure and strengthening the Vista Partnership's financial position dictates reducing debt through an increase in equity capital, the divestiture of non-strategic assets or a combination of the two in order to maintain debt to total capitalization of approximately 50%. Properties Reserves. The estimates of the Vista Partnership's proved oil and gas reserves, which are located entirely within the United States, were prepared in accordance with the guidelines established by the Commission and Financial Accounting Standards Board. The estimates of December 31, 1997, 1996 and 1995 are based on evaluations prepared by the Vista Partnership. For information concerning costs incurred by the Vista Partnership for oil and gas operations, net revenues from oil and gas production, estimated future net revenues attributable to the Vista Partnership's oil reserves and present value of future net revenues on a 10% discount rate and changes therein, see Notes to the Vista Partnership's consolidated financial statements. The Vista Partnership 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 subject to change as further information becomes available. The Vista Partnership's proved reserves totaled 9.1 million BOE at December 31, 1997 with a PV10 of $38.6 million. Reserves increased 59% versus year end 1996. Oil reserves were 7.2 million BOE (a 59% increase over 1996) while gas reserves were 11.3 BCF (a 57% increase over 1996). On a BOE basis, the Vista Partnership's reserves at January 1, 1998 are 52% proved developed with 48% proved undeveloped. Seventy-nine percent of the Vista Partnership's reserves are oil and 21% are gas. The Vista Partnership prefers to operate the properties it owns because operational efficiencies are a key part of the acquisitions targeted by the Vista Partnership. Over 92% of the Vista Partnership's reserve value is attributable to operated properties. Only 8% of the Vista Partnership's reserve value is attributable to properties operated by others. 88 92 The following table summarizes the estimated proved reserves and estimated future cash flows associated with the Vista Partnership's oil and gas properties as estimated in accordance with the definitional requirements under rule 4-10(a) of Regulation S-X. PROVED RESERVES AS OF DECEMBER 31, 1997 1997 AVERAGE DAILY PRODUCTION ------------------------------------------ ------------------------------ NATURAL PV 10 NATURAL OIL GAS VALUE OIL GAS (MBbls) (MMcf) MBOE (000) (Bbls) (Mcf) (BOE) ------- --------- ------- -------- -------- --------- ------- 7,217 11,295 9,100 38,581 1,107 2,148 1,465 Reserve Replacement and Production. For three years, since inception of the company, the Vista Partnership has been able to more than replace its annual production volumes with proved reserves of crude oil and natural gas. During 1997, the Vista Partnership added 3,895 MBOE of reserves, resulting in reserve replacement of 728% of annual production. The reserve replacement rate in 1996 was 919%. Of the 3,895 MBOE of reserves added in 1997, 1,675 MBOE was added through drilling, remedial work and secondary recovery projects, 1,788 MBOE was added through acquisitions of proved reserves, and 432 MBOE was added as a result of revisions. Reserve revisions are a result of either changes in current estimates of reserves or changes in estimates of reserves which are economical to produce given the current pricing conditions. For January 1, 1998, the Vista Partnership received an average oil price of $16.10 per Bbl and an average gas price of $2.01 per Mcf. Should prices either rise or decline in future years, reserves may be revised either upward or downward for quantities that may or may not be economical to produce. The Vista Partnership's production for 1997 averaged 1,463 BOE per day. Production increased during the year from 1,100 per day in January 1997 to 1,800 BOE per day average for December 1997, representing a 63% increase for the year. Based on end of the year production rates, the Vista Partnership's proved reserves to production ratio is 14 years on a BOE basis. This ratio was up from 11 years for year end 1996. Description of Properties. The Vista Partnership manages its oil and gas properties based on geographic areas or producing provinces. The Vista Partnership's two main areas of producing properties include the Permian Basin and the onshore Gulf Coast area of South Texas. Approximately 90% of the Vista Partnership's proved reserves are located in the Permian Basin and 10% are located in the onshore Gulf Coast area of South Texas. The Vista Partnership has no properties outside the United States and has no properties in offshore waters. PERMIAN BASIN The Vista Partnership has a large percentage of its Permian Basin reserves in several prolific fields, including Howard Glasscock, Sharon Ridge, Cowden North and Keystone. Cumulative production from these four fields to January 1, 1998 is over 1.3 billion barrels of oil plus 780 billion cubic feet of natural gas. Each of these large fields can be characterized by multiple reservoirs with substantial primary and secondary reserves remaining to be recovered. The Vista Partnership is attracted to these types of fields due to the huge reserve base remaining and the long lived nature of the reserves, as well as the economies of scale afforded by establishing core areas of operations. Howard -- Glasscock Field, Howard County, Texas This field is located 60 miles east of Midland, Texas and was discovered in 1925. The field has produced over 435 million barrels of oil from wells less than 4,000 feet deep. The Vista Partnership owns a 100% working interest in eight of the nine leases (1,155 net acres) it operates in this field. The field contains Vista's greatest concentration of both proved producing reserves (895 MBOE net) and proved undeveloped reserves (2,615 MBOE net). Accordingly, the Vista Partnership plans to continue to devote a substantial portion of its capital budget and operating resources to the ongoing development of these low risk reserves. Since acquiring these leases less than three years ago, the Vista Partnership has increased gross production by over 300% and expanded or initiated new secondary recovery projects in the Glorieta formation on the Chalk "A," E.O. Chalk and H.R. Clay leases, in the San Andres formation on the G.O. Chalk lease, and in the Middle Clearfork formation on the Douthit, Reed "D" and G.O. Chalk leases. In addition to future production 89 93 increases from secondary recovery projects, the Vista Partnership expects continued growth in production in this area from development drilling of the San Andres formation on the G.O. Chalk, Chalk "A" and H.R. Clay leases. The Vista Partnership owns an interest in 58 producing wells in this field. Sharon Ridge Field, Scurry County, Texas This field is located 80 miles northeast of Midland and has produced over 100 million barrels of oil from depths as shallow as 1700 feet. The Vista Partnership owns a 100% working interest in the two leases (227 net acres) it operates in this field, the Hardee lease and the House lease. These two adjacent properties are located in the middle of the Sharon Ridge (1700 foot) field and are surrounded by successful waterfloods. Since acquiring these properties in 1996, the Vista Partnership has successfully drilled the remaining locations (nine wells) and implemented a full scale waterflood on the two leases. As of January 1998, through infill drilling and early secondary response, production has increased over 300% and Vista expects a continued gradual increase in production as the reservoir is repressured and oil is swept towards the producing wells. The Vista Partnership operates 17 producing wells in this field with net proved producing reserves of 424 MBOE. Cowden North Field, Andrews County, Texas Although the majority of this field is located in Ector County, the Vista Partnership owns Cowden North leases located in Andrews County, approximately 30 miles northwest of Midland, Texas. The Vista Partnership's most significant lease in this field is the Block 9 Unit. This 1,120-acre Grayburg and San Andres unit has produced over 2.35 million barrels of oil from 29 wells since production began in 1959. Since acquiring this property in 1996, the Vista Partnership has drilled three new producing wells which have increased production by over 50%. The unit has eight producing wells with net proved producing reserves of 262 MBOE. Four proved undeveloped locations (246 MBOE net) remain to be drilled as well as several probable locations. The Vista Partnership owns a 100% working interest (1,120 net acres) in this property. Keystone Field, Winkler County, Texas Keystone field is located 50 miles west of Midland and produces from nine different formations with depths ranging from 3,000 feet to 9,000 feet. Since discovery in 1927, the various reservoirs of Keystone field have produced over 319 million barrels of oil and 691 billion cubic feet of natural gas. The Vista Partnership owns a 100% working interest in each of the two leases it operates in the field, the Waddell lease (2,232 net acres, 35 producing wells) and the Keystone Cattle Company lease (640 net acres, 21 producing wells). The Waddell lease has net proved developed producing reserves of 478 MBOE and net proved undeveloped reserves of 43 MBOE. As part of the ongoing process of high grading the Vista Partnership's properties, the Keystone Cattle Company lease has been identified as a likely candidate for future divestment. Other Permian Basin Properties One field with significant unproved reserve potential is the Caprito field in Ward County, Texas. The Vista Partnership owns a 100% working interest in six operated leases (1,884 net acres, 12 producing wells) in the field as well as a 9.4% non operated working interest in an additional nine leases (180 net acres, nine producing wells) operated by Titan Exploration Inc. In addition to the proved developed producing reserves (179 MBOE net from operated and non operated) and proved undeveloped reserves (281 MBOE net) from this field, the HBP acreage is located in the War Wink trend which has produced several recent significant lower Cherry Canyon discoveries. These lower Cherry Canyon sands are approximately 300 feet below the existing Cherry Canyon producing interval in the Caprito field. In Lea County, New Mexico, the Vista Partnership owns a 100% working interest in two Queen sand waterflood units (collectively, 1,880 net acres, 34 producing wells) which produce from a depth of 3,400 feet. Proved producing reserves for the two units are 190 MBOE net. Each of the two units have multiple 20-acre infill drilling locations that the Vista Partnership believes can be developed during periods with favorable commodity prices. 90 94 TEXAS GULF COAST Generally The Vista Partnership acquired several properties in the onshore Gulf Coast area of South Texas in 1997 as part of the E.G. Acquisition. The Vista Partnership plans to continue to add reserves in this gas rich province through acquisitions and drilling. This area is the subject of very active 3-D seismic acquisition and exploratory drilling by the industry. The Vista Partnership intends to enhance the asset value of its existing acreage position in this area by utilizing 3-D seismic when appropriate as well as expand its acreage positions to pursue additional opportunities. North Rucias Field, Brooks County, Texas The Vista Partnership owns a 50% working interest in the Huerta lease (323 net acres, 1 well) and a 46% working interest in the Deluna lease (298 net acres, 1 well) in this 70+ Bcf gas field which produces from the Vicksburg formation at an approximate depth of 10,000 feet. Net proved developed producing reserves from these two leases are 72 MBOE. The Vista Partnership is currently purchasing existing 3-D seismic data and additional leasehold acreage in this area to identify additional drilling opportunities, both on its own acreage and on outside acreage, in this geologically complex reservoir. Drilling results in this Vicksburg trend utilizing 3-D seismic have been very good with exploration activity continuing on all sides of the Vista Partnership's acreage. Orange Hill, South Field, Austin County, Texas The Hillboldt lease (916 net acres) has one lower Wilcox well (net proved developed producing reserves of 268 MBOE) in which the Vista Partnership owns a 91% working interest. The Vista Partnership has contributed some of its acreage and entered into an Area of Mutual Interest agreement with another company for the purpose of drilling additional lower Wilcox wells (net proved undeveloped reserves of 385 MBOE) with the first well scheduled to begin in the summer of 1998. Recent Wilcox completions in this area are having success by adding more productive sands and using larger stimulations than previous wells. In addition to the Wilcox, the Vista Partnership plans to increase gas production by exploiting a known shallow Frio sand with a second quarter 1998 well (net proved undeveloped reserves of 43 MBOE) which will be a twin to the existing well. Finding Cost. The Vista Partnership's acquisition and finding cost for 1997 was $3.17 per BOE as compared to the 1996 and 1995 finding costs of $2.55 and $2.90 per BOE, respectively. The average acquisition and finding cost for the three-year period was $2.90 per BOE. Oil and Gas Mix. The Vista Partnership's reserves were 79% oil and 21% gas at January 1, 1998 and its production mix was 76% oil and 24% gas during 1997. Reserve and production mix may vary somewhat on a short-term basis as the Vista Partnership takes advantage of market conditions and specific acquisition and development opportunities. Management believes that a relative mix of approximately 50% oil and 50% gas is in the best long-term interests of the Vista Partnership and its equity owners. The Vista Partnership intends to continue to look for opportunities to increase its gas reserves to achieve its objective of a closer to 50-50 mix. Drilling Activities. The Vista Partnership seeks to increase its oil and gas reserves, production and cash flow by concentrating on drilling low-risk development wells and by conducting additional development activities such as recompletions on existing wells. In 1997, the company spent approximately $4.7 million on drilling and exploitation. The Vista Partnership has increased its drilling budget in each of the last three years and projects a drilling budget of $5.8 million for developmental and exploratory drilling and other exploitation activities in 1998. At December 31, 1997, the Vista Partnership had over 40 drilling locations to which proved reserves had been assigned. The vast majority of these locations are on leases operated by the Vista Partnership and located in several large fields in the Permian Basin of West Texas and Southeastern New Mexico. 91 95 Production. The following table sets forth the number of gross and net productive and dry wells in which the Vista Partnership had an interest that were drilled and completed during the years ended December 31, 1997 and 1996 and the period from inception (September 21, 1995) to December 31, 1995. This information should not be considered indicative of future performance, nor should it be assumed that there is necessarily any correlation between the number of productive wells drilled and the oil and gas reserves generated thereby or the costs to the Vista Partnership of productive wells compared to the costs of dry wells.

Exploratory Activities. The Vista Partnership is selective with its exploration budget and prefers exploration opportunities that have multiple well potential with no less than 1 MMBOE of reserve potential in plays or areas that the company views as having the ability to provide a near-term impact on the equity value of the Vista Partnership. Since the primary component of Vista's business plan is to acquire and exploit producing properties, exploration activities represent approximately 15% of the Vista Partnership's annual capital budget; however, that is not to say that the Vista Partnership does not recognize the importance of exploration, but rather uses exploration as a value enhancing tool to its existing asset base. The Vista Partnership has successfully utilized 3-D seismic to record at least one new field discovery in each of the last two years and plans to continue to apply this technology in its exploration efforts. The Vista Partnership's expansion into the onshore Gulf Coast region of South Texas was a deliberate move into a producing province that can produce a high success rate on exploration efforts and add significant gas reserves. Exploratory drilling involves greater risks of dry holes and loss of capital than development drilling or enhanced recovery activities. Marketing of Production and Significant Purchasers. Oil and gas production from the Vista Partnership's properties is marketed consistent with usual and customary industry practices which include the sale of oil at the wellhead to third parties and the sale of gas at the wellhead to third parties. Sales prices for both oil and gas production are negotiated based on factors normally considered in the industry, such as the spot price for gas or the posted price for oil, distance from the well to the pipeline, well pressure, estimated reserves, quality of the gas or oil and prevailing supply conditions. During 1997, the Vista Partnership marketed its natural gas and natural gas products to a number of third party purchasers, none of which accounted for 10% or more of the Vista Partnership's revenues. Oil sales are likewise made to a number of third party purchasers. The primary purchasers of the company's crude oil are Genesis Crude Oil, L.P. ("Genesis"), Fina Oil and Chemical Company ("Fina") and Sun Company, Inc. ("Sun"). Approximately 20%, 19% and 18% of the Vista Partnership's 1997 oil sales volumes were made to Genesis, Fina and Sun, respectively. The Vista Partnership is of the opinion that the loss of any one purchaser would not have an adverse effect on its ability to sell its oil and gas production. Hedging Activities. The Vista Partnership periodically enters into commodity derivative contracts (i.e., swaps and collars) in order to (i) reduce the effect of the volatility of price changes on the commodities the Vista Partnership produces and sells, (ii) support the Vista Partnership's annual capital budgeting and expenditure plans, and (iii) lock in prices to protect the economics related to certain capital projects. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of the Vista 92 96 Partnership -- Results of Operations for the Six Months Ended June 30, 1998 and 1997 -- Hedging Activities." Production, Price and Cost Data. The table below sets forth production, price and cost data with respect to the Vista Partnership's properties for the years ended December 31, 1997 and 1996 and the period from inception (September 21, 1995) to December 31, 1995. These amounts are calculated without making pro forma adjustments for any acquisitions, divestitures or drilling activity that occurred during the respective years. 1997 1996 1995 ---------- ---------- ---------- Revenues......................................... $8,874,961 $5,537,720 $1,348,647 Costs and expenses: Production costs............................... 3,688,695 2,544,567 728,540 Depletion...................................... 2,169,098 1,272,316 308,132 Exploration costs.............................. 97,211 273,843 -- ---------- ---------- ---------- 5,955,004 4,090,726 1,036,672 ---------- ---------- ---------- Operating profit (excluding general and administrative expenses and income taxes)... $2,919,957 $1,446,994 $ 311,975 ========== ========== ========== Production: Oil (Bbls)..................................... 403,812 253,321 68,211 Gas (Mcf)...................................... 784,298 458,278 156,515 Total (BOE)............................ 534,528 329,701 94,297 Average Daily Production: Oil (Bbls)..................................... 1,107 693 444 Gas (Mcf)...................................... 2,148 1,255 1,020 ---------- ---------- ---------- Total (BOE)............................ 1,465 902 614 Average Oil Price (Per Bbl)...................... $ 17.63 $ 18.04 $ 15.70 Average Gas Price (Per Mcf)...................... $ 2.22 $ 2.19 $ 1.75 Costs (Per BOE): Lease operating expense........................ $ 5.62 $ 6.35 $ 6.12 Production taxes............................... $ 1.28 $ 1.37 $ 1.61 ---------- ---------- ---------- Total production costs................. $ 6.90 $ 7.72 $ 7.73 Depletion...................................... $ 4.06 $ 3.86 $ 3.27 Productive Wells.

Effective as of June 1, 1998, Midland's wholly owned, operating subsidiary, MRO, and the Vista Operator, entered into a Contract Operating Agreement (herein so called) which provides, among other things, that the Operator will provide various contract operating services for and on behalf of Midland's oil and gas properties through October 31, 1998 and on a month-to-month basis thereafter unless otherwise terminated by either party upon 30 days' prior written notice. For a more detailed description of such agreement, see "The Merger -- Other Agreements" and "Certain Transactions." Financial Advisory Agreement. Contemporaneously with the closing of the Merger, Vista will enter into an Advisory Services Agreement with NGP. Pursuant to the Advisory Services Agreement, Vista will pay NGP $75,000 per year and reimburse NGP for certain expenses in consideration for certain consulting and financial analysis services to be provided by NGP and its representatives. Competition and Markets Competition. The oil and gas industry is highly competitive. A large number of companies and individuals engage in the exploration for and development of oil and gas properties, and there is a high degree of competition for oil and gas properties suitable for development or exploration. Acquisitions of oil and gas properties have been an important element of the Vista Partnership's growth, and Vista intends to continue to acquire oil and gas properties. The principal competitive factors in the acquisition of oil and gas properties include the staff and data necessary to identify, investigate and purchase such properties and the financial resources necessary to acquire and develop them. Many of the Vista Partnership's competitors are substantially larger and have greater financial and other resources than the Vista Partnership. Markets. The Vista Partnership's ability to produce and market oil and gas profitably depends on numerous factors beyond the Vista Partnership's control. The effect of these factors cannot be accurately predicted or anticipated. In recent years, worldwide oil production capacity and gas production capacity in certain areas of the United States have exceeded demand, with resulting declines in the price of oil and gas. Although the Vista Partnership cannot predict the occurrence of events that may affect oil and gas prices or the degree to which oil and gas prices will be affected, it is possible that prices for any oil or gas that the Vista Partnership produces will be lower than those currently available. Any significant decline in the price of oil or gas would adversely affect the Vista Partnership's revenues, profitability and cash flow and could, under certain circumstances, result in a reduction in the carrying value of the Vista Partnership's oil and gas properties. Governmental Regulation The Vista Partnership's oil and gas exploration, production and marketing activities are subject to extensive laws, rules and regulations promulgated by federal and state legislatures and agencies. Failure to comply with such laws, rules and regulations can result in substantial penalties. The legislative and regulatory burden on the oil and gas industry increases the Vista Partnership's cost of doing business and affects its profitability. Although the Vista Partnership believes it is in substantial compliance with all applicable laws and regulations, because those laws and regulations are frequently amended, interpreted and reinterpreted, the Vista Partnership is unable to predict the future cost or impact of complying with such laws and regulations. The State of Texas and many other states require permits for drilling operations, drilling bonds and reports concerning operations and impose other requirements relating to the exploration and production of oil and gas. These states also have statutes or regulations addressing conservation matters, including provisions for the unitization or pooling of oil and gas properties, the establishment of maximum rates of production from wells and the regulation of spacing, plugging and abandonment of such wells. The FERC regulates interstate gas transportation rates and service conditions, which affect the marketing of gas produced by the Vista Partnership, as well as the revenues received by the Vista Partnership for sales of such production. Since the mid-1980s, FERC has issued a series of orders, Order 636, that have significantly altered the marketing and transportation of gas. Order 636 mandates a fundamental restructuring of interstate 94 98 pipeline sales and transportation service, including the unbundling by interstate pipelines of the sale, transportation, storage and other components of the city-gate sales services such pipelines previously performed and the provision of open-access transportation on a nondiscriminatory basis. One of FERC's purposes in issuing the order was to increase competition within all phases of the gas industry. Numerous parties have filed petitions for review of Order 636, as well as orders in individual pipeline restructuring proceedings. In July 1996, Order 636 was generally upheld on appeal, and the portions remanded for further action do not appear to materially affect the Vista Partnership. Because Order 636 may be modified as a result of the appeals, it is difficult to predict the ultimate impact of the orders on the Vista Partnership and its gas marketing efforts. Generally, Order 636 has eliminated or substantially reduced the interstate pipelines' traditional role as wholesalers of gas and has substantially increased competition and volatility in gas markets. The FERC frequently reexamines its transportation-related policies, including the terms and conditions under which interstate pipeline shippers may release interstate pipeline capacity for resale in the secondary market, the appropriateness of the use of negotiated and market-based rates, and the implementation of additional standardized terms and conditions for interstate gas transmission. In April 1998, the FERC issued a new rule to further standardize pipeline transportation tariffs that could adversely affect the reliability of scheduled interruptible transportation service on some pipelines. While any resulting FERC action would affect the Vista Partnership only indirectly, any new rules and policy statements may have the effect of enhancing competition in gas markets or affecting the cost or availability of pipeline transportation. The price the Vista Partnership receives from the sale of oil and gas is affected by the cost of transporting products to markets. Effective January 1, 1995, FERC implemented regulations establishing an indexing system for transportation rates for oil pipelines, which, generally, would index such rates to inflation, subject to certain conditions and limitations. The Vista Partnership is not able to predict with certainty the effect, if any, of these regulations on its operations. However, the regulations may increase transportation costs or reduce well head prices for oil and gas. See "Risk Factors -- Governmental Regulation and Environmental Matters." Environmental Matters The Vista Partnership's operations and properties are, like the oil and gas industry in general, subject to extensive and changing federal, state and local laws and regulations relating to environmental protection, including the generation, storage, handling, emission, transportation and discharge of materials into the environment, and relating to safety and health. The recent trend in environmental legislation and regulation generally is toward stricter standards, and this trend will likely continue. These laws and regulations may require the acquisition of a permit or other authorization before construction or drilling commences and for certain other activities; limit or prohibit construction, drilling and other activities on certain lands lying within wilderness and other protected areas; and impose substantial liabilities for pollution resulting from the Vista Partnership's operations. The permits required for various of the Vista Partnership's operations are subject to revocation, modification and renewal by issuing authorities. Governmental authorities have the power to enforce compliance with their regulations, and violations are subject to fines or injunction, or both. In the opinion of management, the Vista Partnership is in substantial compliance with current applicable environmental laws and regulations, and the Vista Partnership has no material commitments for capital expenditures to comply with existing environmental requirements. Nevertheless, changes in existing environmental laws and regulations or in interpretations thereof could have a significant impact on the Vista Partnership, as well as the oil and gas industry in general. CERCLA and comparable state statutes impose strict and arguably joint and several liability on owners and operators of certain sites and on persons who dispose of or arranged for the disposal of "hazardous substances" found at such sites. Under CERCLA, such persons may be subject to liability for the costs of cleaning up the hazardous substances, for damages to natural resources and for the costs of certain health studies. Furthermore, it is not uncommon for the neighboring land owners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances related into the environment. RCRA and comparable state statutes govern the disposal of "solid waste" and "hazardous waste" and authorize imposition of substantial fines and penalties for noncompliance. Although CERCLA currently excludes petroleum from its definition of "hazardous substance," state laws affecting the Vista 95 99 Partnership's operations impose clean-up liability relating to petroleum and petroleum related products. In addition, although RCRA classifies certain oil field wastes as "non-hazardous," such exploration and production wastes could be reclassified as hazardous wastes thereby making such wastes subject to more stringent handling, disposal and cleanup requirements. Federal regulations require certain owners or operators of facilities that store or otherwise handle oil, such as the Vista Partnership, to prepare and implement spill prevention, control countermeasure and response plans relating to the possible discharge of oil into surface waters. OPA contains numerous requirements relating to the prevention of and response to oil spills into waters of the United States. For onshore and offshore facilities that may affect waters of the United States, the OPA requires an operator to demonstrate financial responsibility. Regulations are currently being developed under federal and state laws concerning oil pollution prevention and other matters that may impose additional regulatory burdens on the Vista Partnership. In addition, the Clean Water Act and analogous state laws require permits to be obtained to authorize discharge into surface waters or to construct facilities in wetland areas. With respect to certain of its operations, the Vista Partnership is required to maintain such permits or meet general permit requirements. The EPA recently adopted regulations concerning discharges of storm water runoff. This program requires covered facilities to obtain individual permits, participate in a group or seek coverage under an EPA general permit. The Vista Partnership believes that it will be able to obtain, or be included under, such permits, where necessary, and to make minor modifications to existing facilities and operations that would not have a material effect on the Vista Partnership. The Vista Partnership has acquired leasehold interests in numerous properties that for many years have produced oil and gas. Although the previous owners of these interests have used operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties. In addition, some of the Vista Partnership's properties are operated by third parties over whom the Vista Partnership has no control. Notwithstanding the Vista Partnership's lack of control over properties operated by others, the failure of the operator to comply with applicable environmental regulations may, in certain circumstances, adversely impact the Vista Partnership. See "Risk Factors -- Governmental Regulation and Environmental Matters." Employees On September 11, 1998, the Vista Partnership had 23 full-time employees. None is represented by any labor union. The Vista Partnership believes that its relations with its employees are good. Litigation The Vista Partnership is not a party to any material legal proceedings.

The Merger Agreement provides that from and after the Effective Time, the Surviving Subsidiary shall indemnify and hold harmless each person and shall advance expenses incurred by each person who is, has been at any time prior to the date hereof, or becomes prior to the Effective Time an officer or director of Midland or any of its subsidiaries (collectively, the "Midland Indemnified Parties") against all losses, claims, damages, liabilities, costs or expenses (including attorney's fees), judgments, and amounts paid in settlement in connection with any claim, action, suit, proceeding, or investigation arising out of or pertaining to acts or omissions, or alleged acts or omissions, by him in his capacity as an officer or director of Midland or any of its subsidiaries, which acts or omissions occurred prior to the Effective Time, to the full extent permitted by applicable law and by the Bylaws of Midland in effect prior to the Effective Time, which Bylaws make mandatory the indemnification of and advancement of expenses to all Midland Indemnified Parties to the full extent permitted by the TBCA (as defined herein). The procedures associated with such indemnification shall be the same as those associated with the Midland Indemnified Parties' indemnification from Midland or any of its respective subsidiaries, as the case may be, immediately prior to the Effective Time (provided, however, that the determination that such indemnification is permissible under the TBCA shall be made by special legal counsel selected by the Board of Directors as set forth in the TBCA, such selection to be subject to the consent of a majority of the Midland Indemnified Parties in such instance, which consent may not be unreasonably withheld; and, further provided, however, that the Surviving Subsidiary shall be under no obligation to deposit trust funds pursuant to any "change-in-control" or similar provisions). Midland hereby agrees that, from and after the date hereof until the Effective Time, it will not (and it will cause each of its subsidiaries not to) amend, modify, or otherwise alter any contractual provision under which any Midland Indemnified Party is entitled to indemnification from Midland or any of its subsidiaries, as the case may be, at the time of the execution of the Merger Agreement.

The procedures associated with such indemnification shall be the same as those associated with the Vista Indemnified Parties' indemnification from the Vista Partnership or any of its subsidiaries, as the case may be, immediately prior to the Effective Time (provided, however, that the Vista Partnership shall be under no obligation to deposit trust funds pursuant to any "change-in-control" or similar provisions). The Vista Partnership hereby agrees that, from and after the date hereof until the Effective Time, it will not (and it will cause each of its subsidiaries not to) amend, modify, or otherwise alter any contractual provision under which any Vista Indemnified Party is entitled to indemnification from the Vista Partnership or any of its subsidiaries at the time of the execution of the Merger Agreement. The indemnification provisions of the Merger Agreement are intended to be for the benefit of, and shall be enforceable by, the parties hereto and each Vista Indemnified Party and their respective heirs and representatives.

The services to be provided shall be as requested by Midland and shall include, without limitation, field operations services, engineering supervision and analysis, geological review and analysis, land and legal analysis, well site supervision for drilling activities, and accounting and production overview and supervision. All field level services shall be charged to Midland on an actual cost basis as incurred by the Operator, engineering and geological review and supervision shall be charged at a flat rate of $400 per day with a half day minimum charge, and limited general and administrative assistance will be charged at a flat rate of $1,500 per month (which increases to $3,000 per month on November 1, 1998). Any general and administrative services requested by Midland beyond the limited services set out in the Contract Operating Agreement shall be charged on agreed upon hourly rates for the number and type of Operator employees utilized by Midland. Contemporaneously with the closing of the Merger, Vista will enter into an Advisory Services Agreement with NGP. Pursuant to the Advisory Services Agreement, Vista will pay NGP $75,000 per year on a year-to-year basis and reimburse NGP for certain expenses in consideration for certain consulting and financial analysis services to be provided by NGP and its representatives. During 1996, Midland conducted a cash tender offer for all of the common stock and options of Summit Petroleum Corporation ("Summit"), a public oil and gas corporation of which Mr. Warley was President, Treasurer and Chairman and owned approximately 37.5% of its common stock, and Darrell M. Dillard and Wayne M. Whitaker were directors, stockholders and option holders. Midland completed the acquisition of Summit through a merger with a wholly owned subsidiary in December 1996. Midland received a fairness opinion regarding the tender offer price of $.70 per share (net of any option exercise prices). As a result of this offer Messrs. Warley, Dillard and Whitaker received total proceeds of $660,000, $31,875 and $49,375, respectively. $479,647 of the proceeds due Mr. Warley from the Summit tender offer discussed above, were used to repay the balance outstanding under a promissory note of Mr. Warley due Midland that was entered into in December 1995, whereby Mr. Warley borrowed $582,805 under an 18-month term note bearing 7.5 % interest, secured by 287,947 shares of Midland Common Stock. The original proceeds of this loan were used by Mr. Warley to exercise 233,122 warrants to buy Midland Common Stock at $2.50 per share that were received in 1990 upon the formation of Midland. Midland purchased a building and land in Midland County, Texas for $78,996 from Mr. Warley and another individual for use as a district office, effective November 1, 1995. Mr. Warley and the other individual each financed 50% of the purchase price less the down payment of $10,496. The two $34,250 ten-year notes bore interest at 7.5% and were payable in equal monthly installments of $407, each. The cost to Midland was based on an independent written appraisal and certain improvements completed before the property was purchased. The balance of the note payable to Mr. Warley was netted against his $582,805 note payable discussed above, together with a cash payment of $95,000, leaving a balance of $453,641 on Mr. Warley's note due Midland. Until Midland acquired Summit, MRO had a management agreement with Summit. Total management fees charged Summit for 1996 were $45,000. Mr. Warley had a five-year employment contract with Midland that was terminated by the Midland Board on March 27, 1998. As of that date, the employment contract provided for an annual salary of $247,963 with a minimum 5% semi-annual adjustment. Mr. Warley waived such adjustments for 1997. In addition, the contract provided for medical reimbursement of up to $10,000 for non-insurance covered medical expenses, disability payments of one-half the annual salary for 10 years and a covenant not to compete with Midland for six months. The term of the agreement extended for an additional five years each January 1, unless notice was 111 115 given by either Mr. Warley or Midland. Following termination of Mr. Warley's contract and pending the conclusion of negotiations with respect to the Merger Agreement, Midland and Mr. Warley agreed to Midland paying Mr. Warley one-half of his former monthly salary and providing him the use of a company vehicle. On May 22, 1998, Midland and Mr. Warley executed that certain Warley Settlement Agreement, to be effective March 27, 1998, containing the following principal terms: (i) from March 27, 1998, through either the consummation or termination of the Merger Agreement, Midland shall pay Warley the sum of $11,390 per month; (ii) on the effective date of the Merger, Midland agrees to pay to Warley the sum of $1,300,000 (reduced by a payment of $100,000 made by Midland to Marilyn D. Wade on behalf of Mr. Warley pursuant to the Wade Release (as defined below)), payable $20,000 a month over sixty (60) months, provided that, after one year, either Midland or Warley may elect to have such amount paid as a lump sum (using a discount factor of six percent (6%)); (iii) Warley's existing Midland stock options for 15,000 shares shall expire on the 120th day following the effective date of the Merger; (iv) Warley agrees to support the Merger and to take or refrain from taking actions as contemplated by the Merger Agreement; and (v) Warley and Midland mutually release one another from all claims which either party may have (including a release by Warley of Midland's directors and officers) except pursuant to such Agreement and pursuant to confidentiality and non-compete provisions in Warley's employment agreement and Warley's rights to indemnification as officer and director of Midland. Mr. Whitaker, a director since 1996, is a partner in the law firm of Michener, Larimore, Swindle, Whitaker, Flowers, Sawyer, Reynolds & Chalk, L.L.P. During 1997 and 1996 Midland paid $126,278 and $85,749 respectively, to that firm for legal services and costs. Mr. Dillard, a director since 1994, served as Chief Financial Officer during the period October 31, 1995 until February 1997. Midland paid Mr. Dillard $46,001 and $4,000 respectively, during 1997 and 1996 for accounting and consulting services, and officer compensation of $66,543 in 1996. Mr. Donnelly, a director since 1990, was until November 1997 a partner in EOC Services Co., which provided oilfield services to Midland and that firm was paid $26,449 in 1997. Mr. Brock, a director since 1995, is an officer of Citation Crude Oil Marketing, Inc. a company which provided crude oil marketing services to Midland in 1997 and that firm was paid $14,000. On January 14, 1997 Midland formed Chalk Mountain Exploration, Ltd. ("Partnership"), a Texas limited partnership, and became its general partner, and sold to that limited partnership certain 3-D seismic data and related leases. With respect to the specific 3-D seismic project, Midland sold that data and 100% of its interest in the related leases for $383,975, which represented its total cost in such project. In addition to providing the funding for the purchase of the 3-D seismic data and lease costs, the limited partners provided $366,025 to drill the first exploratory well to completion, with Midland providing $407,597 for 100% of the completion costs. After the initial exploratory well, Midland and the limited partners shared costs equally. In exchange for providing the initial $750,000 of funding to the Partnership, the limited partners received 50% of its profits and Midland as general partner received 50%. Two additional exploratory wells and one development well were drilled in 1997 with Midland bearing 50% of the cost of the drilling of these wells ($958,164) and the limited partners bearing 50% of such costs, with the limited partners electing not to participate in the completion of one such exploratory well. Further, Midland contributed $406,250 as its 50% of additional acreage costs in 1997. Messrs. Dillard, Whitaker and Adams were limited partners. Midland acts as operator on the leases and supervises the drilling of any wells, for which it receives fees from the limited partnership which are customary within the industry. Effective July 1, 1997 Midland and Mr. Dillard exchanged substantially all their partnership interests for the direct assignment of an equivalent working interest in the related leases and Mr. Whitaker exchanged all of his Partnership interest in exchange for an equivalent working interest. Thereafter effective October 1, 1997 Messrs. Whitaker and Dillard sold their working interests in the related wells and leases to Midland for $57,848 and $87,031 and 5,000 unregistered shares and 10,040 unregistered shares respectively. Mr. Dillard's sale also included his remaining limited partner interest in the Partnership. Effective December 31, 1997 Midland withdrew as the General Partner and conveyed all of its Partnership interest back to the Partnership in settlement of a dispute involving reimbursement of the cost of a well drilled through a zone not owned by the Partnership. 112 116 On May 22, 1998, Midland, Mr. Warley, and Marilyn Wade executed that certain Release and Hold Harmless Agreement (the "Wade Release") containing the following principal terms and provisions: (i) Wade agrees to resign her employment upon consummation of the Merger; (ii) Warley agrees to pay the sum of $100,000 to Wade upon consummation of the Merger, which payment Midland has agreed to pay to Wade on behalf of Warley under the Warley Settlement Agreement; (iii) upon execution of the Wade release, Midland granted Wade options to purchase 137,931 shares of Midland Common Stock at $2.6875 per share; (iv) within three (3) business days after Wade's resignation, Midland agrees to pay the sum of $56,590; and (v) Wade releases Warley, Midland and Midland's directors and officers from all claims which she may have against them. DESCRIPTION OF VISTA CAPITAL STOCK The authorized capital stock of Vista consists of 50,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. VISTA COMMON STOCK All shares of Vista Common Stock issued in the Merger will be fully paid and nonassessable. The holders of Vista Common Stock are entitled to one vote for each share held on all matters submitted to a vote of common stockholders. The Vista Common Stock does not have cumulative voting rights or preemptive rights. Subject to the rights of the holders of any class of capital stock of Vista having any preference or priority over the Vista Common Stock, the holders of Vista Common Stock are entitled to dividends in such amounts as may be declared by the Vista Board from time to time out of any funds legally available for such payments and, in the event of liquidation, to share ratably in the assets of Vista remaining after provision for any liquidation preferences on any outstanding preferred stock ranking prior to the Vista Common Stock. VISTA PREFERRED STOCK The Vista Board, without further stockholder action, is authorized to issue up to 10,000,000 shares of preferred stock, par value $.01 per share ("Vista Preferred Stock") in one or more series and to fix and determine as to any series all the relative rights and preferences of shares in the series, including voting rights, dividend rights, liquidation preferences, terms of redemption and conversion rights. Although Vista has no present intention to issue shares of Vista Preferred Stock, the issuance of shares of Vista Preferred Stock, or the issuance of rights to purchase such shares, could be used to discourage an unsolicited acquisition proposal. For instance, the issuance of a series of Vista Preferred Stock might impede a business combination by including class voting rights that would enable the holders to block such a transaction; or such issuance might facilitate a business combination by including voting rights that would provide a required percentage vote of the stockholders. In addition, under certain circumstances, the issuance of Vista Preferred Stock could adversely affect the voting power of the holders of the Vista Common Stock. Although the Vista Board is required to make any determination to issue such stock based on its judgment as to the best interests of the stockholders of Vista, the Vista Board could act in a manner that would discourage an acquisition attempt or other transaction in that some or a majority of the stockholders might believe to be in their best interest or in which stockholders might receive a premium for their stock over the then market price of such stock. The Vista Board does not at present intend to seek stockholder approval prior to any issuance of currently authorized stock, unless otherwise required by law or the regulations of the exchange on which the Vista Common Stock is listed. DELAWARE ANTI-TAKEOVER STATUTE Vista is a Delaware corporation and is subject to Section 203 of the Delaware General Corporation Law. In general, Section 203 prevents an "interested stockholder" (defined generally as a person owning 15% or more of Vista's outstanding voting stock) from engaging in a "business combination" (as defined in Section 203) with Vista for three years following the date that person becomes an interested stockholder 113 117 unless (a) before that person became an interested stockholder, Vista's Board of Directors approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination, (b) upon completion of the transaction that resulted in the interested stockholder's becoming an interested stockholder, the interested stockholder owns at least 85% of Vista voting stock outstanding at the time the transaction commenced (excluding stock held by directors who are also officers of Vista and by employee stock plans that do not provide employees with the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer), or (c) following the transaction in which that person became an interested stockholder, the business combination is approved by Vista's Board of Directors and authorized at a meeting of stockholders by the affirmative vote of the holders of at least two-thirds of the outstanding Vista voting stock not owned by the interested stockholder. Under Section 203, these restrictions also do not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of one of certain extraordinary transactions involving Vista and a person who was not an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of Vista's directors, if that extraordinary transaction is approved or not opposed by a majority of the directors who were directors before any person became an interested stockholder in the previous three years or who were recommended for election or elected to succeed such directors by a majority of such directors then in office. Section 203 will not be applicable to Vista by reason of consummation of the Merger or consummation of any of the other the transactions contemplated by the Merger Agreement. In addition, none of the holders of Vista Common Stock subsequent to the Effective Time will become an interested stockholder as a result of such transactions. VISTA STOCK OPTION PLAN The description set forth below represents a summary of the principal terms and conditions of the Vista Stock Option Plan and does not purport to be complete. Such description is qualified in its entirety by reference to the Vista Energy Resources, Inc. 1998 Key Employee Stock Option Plan (the "Vista Stock Option Plan"), a copy of which is attached as Appendix E to this Proxy Statement/Prospectus. GENERAL Vista may grant awards with respect to shares of Vista Common Stock under the Vista Stock Option Plan to officers, directors and employees of Vista or any parent or subsidiary corporation of Vista. At the Effective Time, Vista is expected to have six directors and approximately 24 employees. The awards under the Vista Stock Option Plan include (i) incentive stock options qualified as such under U.S. federal income tax laws and (ii) stock options that do not qualify as incentive stock options. The number of shares of Vista Common Stock that may be subject to outstanding awards under the Vista Stock Option Plan is 900,000. The Board of Directors of Vista or any committee designated by it may administer the Vista Stock Option Plan (as used for the Vista Stock Option Plan, the "Committee"). The Committee has broad discretion to administer the Vista Stock Option Plan, interpret its provisions and adopt policies for implementing the Vista Stock Option Plan. This discretion includes the ability to select the recipient of an award, determine the type and amount of each award, establish the terms of each award, accelerate vesting or exercisability of an award, determine whether performance conditions have been satisfied and otherwise modify or amend any award under the Vista Stock Option Plan. Nevertheless, no awards for more than 250,000 shares may be granted to any one employee in a calendar year. AWARDS The Committee determines the exercise price of each option granted under the Vista Stock Option Plan. The exercise price for an incentive stock option must not be less than the fair market value of the Vista Common Stock on the date of grant. Stock options may be exercised as the Committee determines, but not later than ten years from the date of grant in the case of incentive stock options. At the discretion of the 114 118 Committee, holders may use shares of stock to pay the exercise price, including shares issuable upon exercise of the option. OTHER PROVISIONS At the Committee's discretion and subject to conditions that the Committee may impose, a participant's tax withholding with respect to an award may be satisfied by the withholding of shares of Vista Common Stock issuable pursuant to the award or the delivery of previously owned shares of Vista Common Stock, in either case based on the fair market value of the shares. If a change of control shall occur or Vista shall enter into an agreement providing for a change of control, then the Committee may declare any or all options outstanding under the Vista Stock Option Plan to be exercisable in full at such time or times as the Committee shall determine. Each option accelerated by the Committee pursuant to the preceding sentence shall terminate on such date (not later than the stated exercise date) as the Committee shall determine. Without stockholder approval, the Vista Board may not amend the Vista Stock Option Plan to increase the total number of shares of Vista Common Stock that may be issued under the Vista Stock Option Plan. Otherwise, the Vista Board may at any time alter, amend, modify, suspend or terminate the Vista Stock Option Plan. No award may be issued under the Vista Stock Option Plan after the tenth anniversary of stockholder approval of the plan. TAX IMPLICATION OF AWARDS Set forth below is a summary of the federal income tax consequences to employees, directors and other participants in the Vista Stock Option Plan ("Vista Employees") and to Vista as a result of the grant and exercise of awards under the Vista Stock Option Plan. This summary is based on statutory provisions, Treasury regulations thereunder, judicial consents and IRS rulings in effect on the date hereof. Nonqualified Stock Options; Incentive Stock Options. Vista Employees will not realize taxable income upon the grant of a non-qualified stock option ("NQSO"). Upon the exercise of a NQSO, a Vista Employee will recognize ordinary compensation income (subject to withholding by Vista) in an amount equal to the excess of (i) the amount of cash and the fair market value of Vista Common Stock received, over (ii) the exercise price (if any) paid therefor. A Vista Employee will generally have a tax basis in any shares of Vista Common Stock received pursuant to the cash exercise of a NQSO, that equals the fair market value of such shares on the date of exercise. Subject to the discussion under "-- Tax Code Limitations on Deductibility," Vista (or a subsidiary) will be entitled to a deduction for federal income tax purposes that corresponds as to timing and amount with the compensation income recognized by a Vista Employee under the foregoing rules. Vista Employees eligible to receive an incentive stock option ("ISO") will not have taxable income on the grant of an ISO. Upon the exercise of an ISO, a Vista Employee will not have taxable income, although the excess of the fair market value of the shares of Vista Common Stock received upon exercise of the ISO ("ISO Stock") over the exercise price will increase the alternative minimum taxable income of the Vista Employee, which may cause such Vista Employee to incur alternative minimum tax. The payment of any alternative minimum tax attributable to the exercise of an ISO would be allowed as a credit against the Vista Employee's regular tax liability in a later year to the extent the Vista Employee's regular tax liability is in excess of the alternative minimum tax for that year. Upon the disposition of ISO Stock that has been held for the requisite holding period (generally, at least two years from the date of grant and one year from the date of exercise of the ISO), a Vista Employee will generally recognize capital gain (or loss) equal to the excess (or shortfall) of the amount received in the disposition over the exercise price paid by the Vista Employee for the ISO Stock. However, if a Vista Employee disposes of ISO Stock that has not been held for the requisite holding period (a "disqualifying disposition"), the Vista Employee will recognize ordinary compensation income in the year of the disqualifying disposition in an amount equal to the amount by which the fair market value of the ISO Stock at the time of exercise of the ISO (or, if less, the amount realized in the case of an arm's length disqualifying disposition 115 119 to an unrelated party) exceeds the exercise price paid by the Vista Employee for such ISO Stock. A Vista Employee would also recognize capital gain to the extent the amount realized in the disqualifying disposition exceeds the fair market value of the ISO stock on the exercise date. If the exercise price paid for the ISO Stock exceeds the amount realized (in the case of an arm's-length disposition to an unrelated party), such excess would ordinarily constitute a capital loss. Vista and its subsidiaries will generally not be entitled to any federal income tax deduction upon the grant or exercise of an ISO, unless a Vista Employee makes a disqualifying disposition of the ISO Stock. If a Vista Employee makes a disqualifying disposition, Vista (or a subsidiary) will then, subject to the discussion below under "-- Tax Code Limitations on Deductibility," be entitled to a tax deduction that corresponds as to timing and amount with the compensation income recognized by a Vista Employee under the rules described in the preceding paragraph. Under current rulings, if a Vista Employee transfers previously held shares of Vista Common Stock (other than ISO Stock that has not been held for the requisite holding period) in satisfaction of part or all of the exercise price of an NQSO or ISO, no additional gain will be recognized on the transfer of such previously held shares in satisfaction of the NQSO or ISO exercise price (although a Vista Employee would still recognize ordinary compensation income upon exercise of an NQSO in the manner described above). Moreover, that number of shares of Vista Common Stock received upon exercise which equals the number of shares of previously held Vista Common Stock surrendered therefor in satisfaction of the NQSO or ISO exercise price will have a tax basis that equals, and a holding period that includes, the tax basis and holding period of the previously held shares of Vista Common Stock surrendered in satisfaction of the NQSO or ISO exercise price. Any additional shares of Vista Common Stock received upon exercise will have a tax basis that equals the amount of cash (if any) paid by the Vista Employee, plus the amount of compensation income recognized by the Vista Employee's transfer of previously held Vista Common Stock in full or partial satisfaction of the exercise price of an ISO or NQSO, the tax consequences of the reload option will be as provided above for an ISO or NQSO, depending on whether the reload option itself is an ISO or NQSO. A Vista Employee will be subject to withholding for federal, and generally for state and local, income taxes at the time he recognizes income under the rules described above with respect to Vista Common Stock or cash received. Dividends that are received by a Vista Employee prior to the time that the Vista Common Stock is taxed to the Vista Employee under the rules described in the preceding paragraph are taxed as additional compensation, not as dividend income. The tax basis of a Vista Employee in the Vista Common Stock received will equal the amount recognized by him as compensation income under the rules described in the preceding paragraph, and the Vista Employee's holding period in those shares will commence on the date of receipt of the shares. Subject to the discussion immediately below, Vista (or a subsidiary) will be entitled to a deduction for federal income tax purposes that corresponds as to timing and amount with the compensation income recognized by a Vista Employee under the foregoing rules. Tax Code Limitations and Deductibility. In order for the amounts described above to be deductible by Vista (or a subsidiary), such amounts must constitute reasonable compensation for services rendered or to be rendered and must be ordinary and necessary business expenses. The ability of Vista (or a subsidiary) to obtain a deduction for future payments under the Vista Stock Option Plan could also be limited by the golden parachute payment rules of Section 280G of the Code, which prevent the deductibility of certain excess parachute payments made in connection with a change in control of an employer-corporation. Finally, the ability of Vista (or a subsidiary) to obtain a deduction for amounts paid under the Vista Stock Option Plan could be limited by Section 162(m) of the Code, which limits the deductibility, for federal income tax purposes, of compensation paid to certain executive officers of Vista to $1 million with respect to any such officer during any taxable year of Vista. However, an exception applies to this limitation in the case of certain performance-based compensation. The Vista Stock Option Plan is intended to satisfy the requirements for the performance-based exception. Vista intends to comply with the requirements of the Code with respect to awards under the Vista Stock Option Plan so as to be eligible for the performance-based exception, but Vista 116 120 may, in its sole discretion, determine that in one or more cases it is in its best interests to not satisfy the requirements for the performance-based exception. REGISTRATION RIGHTS FOR VISTA STOCKHOLDERS The Merger Agreement provides that contemporaneously with the Closing, Vista shall enter into separate registration rights agreements (collectively, the "Registration Rights Agreements") with each of the stockholders of the General Partner and each of the limited partners of the Vista Partnership immediately prior to the Vista Exchange and with each holder of a Midland Exchange Stock Option covering (i) with respect to the Vista securityholders, the resale of shares of Vista Common Stock to be received by such securityholders pursuant to the terms of the Vista Exchange Agreement, together with all shares of Vista Common Stock issuable to such securityholders upon the exercise of an Exchange Warrant, (ii) with respect to the Midland securityholders, the resale of shares of Vista Common Stock issuable to such securityholders upon the exercise of an Exchange Warrant and (iii) any securities issued or issuable in respect of any such shares by way of any stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization or otherwise ((i), (ii) and (iii) above collectively referred to as the "Registrable Shares"). The Registration Rights Agreements provide that the holders of more than 50% of the Registrable Shares outstanding may, at any time after the first anniversary of the Effective Time, require Vista to effect the registration under the Securities Act of Registrable Shares on no more than two occasions by means of a "shelf" registration statement for an offering to be made on a continuous basis under the Securities Act, subject to certain limitations. The Registration Rights Agreements also provide certain "piggyback" registration rights to the holders of Registrable Shares whenever Vista proposes to register an offering of any of its capital stock under the Securities Act, subject to certain exceptions, including pro rata reduction if, in the reasonable opinion of the managing underwriter(s) of the offering, such a reduction is necessary to prevent an adverse effect on the marketability or offering price of all the securities proposed to be offered in the offering. The Registration Rights Agreements contain customary provisions regarding the payment of expenses by Vista and regarding mutual indemnification agreements between Vista and the holders of Registrable Shares for certain securities law violations. COMPARISON OF STOCKHOLDER RIGHTS The following is a summary of certain provisions affecting, and the differences between the rights of holders of the capital stock of Vista and Midland, respectively. Since Midland is a Texas corporation and Vista is a Delaware corporation, the differences between the rights of Midland stockholders and the Vista stockholders will arise from the various differences between the Texas Business Corporation Act ("TBCA") and the Delaware General Corporation Law ("DGCL") as well as from the differences between the various provisions of the Midland Articles of Incorporation ("Midland Charter") and the Midland Bylaws ("Midland Bylaws") and the Vista Certificate of Incorporation ("Vista Charter") and Vista Bylaws ("Vista Bylaws"). The following summary is qualified in its entirety by reference to the TBCA, the DGCL, the complete text of the Midland Charter and Bylaws and the Vista Charter and Bylaws. The Vista Charter and the Vista Bylaws have been filed as exhibits to this Proxy Statement/Prospectus. See "Available Information." As a result of the Merger, holders of Midland Common Stock will become holders of Vista Common Stock. The rights of all former Midland stockholders will thereafter be governed by the Vista Charter, the Vista Bylaws and the DGCL. The rights of the holders of Midland Common Stock are currently governed by the Midland Charter, the Midland Bylaws and the TBCA. The following summary, which does not purport to be a complete statement of the general differences among the rights of stockholders of Midland and Vista, sets forth certain differences between the Midland Charter and the Vista Charter, the Midland Bylaws and the Vista Bylaws and the TBCA and the DGCL. 117 121 AUTHORIZED CAPITAL STOCK Midland. Midland's authorized capital stock consists of 100,000,000 shares of common stock, par value $.001 per share. Midland has not authorized the issuance of shares of preferred stock. Vista. Vista's authorized capital stock consists of 60,000,000 shares, divided into 50,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. VOTING Midland. Each share of Midland Common Stock entitles the holder to one vote on each matter submitted to stockholders. Vista. Each share of Vista Common Stock entitles the holder to one vote on each matter submitted to stockholders. Each share of Vista Preferred Stock, when and if designated and issued, will entitle the holder to such voting rights as shall be specified in the certificate of designations establishing such shares. SPECIAL MEETINGS OF STOCKHOLDERS Midland. The Midland Bylaws provide that a special meeting of stockholders may be called by the chairman of the Midland Board, the president, any one of the directors or the holders of not less than one-tenth of all the shares having voting power at such meeting. Vista. The Vista Bylaws provide that a special meeting of stockholders may be called only by the Vista Board. DIRECTORS Midland. The Midland Bylaws provide that the number of directors shall be not less than three nor more than 11. The exact number of directors shall be five until changed, within the preceding limits, by resolutions amending such exact number, duly adopted by at least 75% of the entire Midland Board, or the affirmative vote of the stockholders holding a majority of the shares entitled to vote on the election of directors; and provided that no decrease shall effect a shortening of the term of any incumbent director. The stockholders do not have the right to cumulate their votes in the election of directors. Vista. The Vista Charter provides for a Board of Directors consisting of a number of members to be determined by the resolution of the Board of Directors, but will in no event be less than two or more than 21. The stockholders do not have the right to cumulate their votes in the election of directors. REMOVAL OF DIRECTORS Midland. The Midland Bylaws provide that at any special meeting called for such purpose, any director or the entire Board of Directors may be removed from office, with or without cause, by the affirmative vote of a majority of the shares present in person or by proxy and entitled to vote at such meeting. Vista. The Vista Bylaws provide that a director may be removed only for cause and by an affirmative vote of a majority of the shares entitled to vote thereon cast at the annual meeting of the stockholders or any special meeting of stockholders called expressly for that purpose by a majority of the members of the Board of Directors serving at the time of that vote. VACANCIES ON THE BOARD OF DIRECTORS Midland. The Midland Bylaws provide that any vacancy occurring in the Board of Directors may be filled by the vote of a majority of the remaining directors, though less than a quorum. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office. Any position on the Board of Directors to be filled by reason of an increase in the number of directors shall be filled by the vote of a majority of the directors, election at an annual meeting of the stockholders, or at a special meeting of stockholders, duly 118 122 called for such purpose, provided that the Board of Directors may fill no more than two such directorships between any two successive annual meetings of the stockholders. Vista. The Vista Bylaws provide that any vacancy occurring in the Board of Directors or any directorship to be filled by reason of an increase in the number of directors may be filled (a) by no less than a majority of the remaining directors then in office, though less than a quorum, for a term of office continuing only until the next election of one or more directors by the stockholders or (b) by election at an annual or special meeting of stockholders called for that purpose. MERGERS AND OTHER FUNDAMENTAL TRANSACTIONS Midland. The TBCA generally requires that a merger, consolidation, sale of all or substantially all of the assets or dissolution of a corporation be approved by the holders of at least two-thirds of the outstanding shares of stock entitled to vote, unless such corporation's articles of incorporation provide otherwise. The Midland Charter contains no such provision; therefore, the TBCA provision described above applies to Midland. Vista. Under the DGCL, mergers, consolidations or sales of substantially all of the assets or dissolution of a corporation generally must be approved by the holders of at least a majority of all outstanding shares of stock entitled to vote, unless the certificate of incorporation requires approval by a greater number of shares of stock. The Vista Charter contains no such provision; therefore, the DGCL provision described above applies to Vista. AMENDMENTS TO CERTIFICATE OF INCORPORATION Midland. Article 4.02 of the TBCA provides that an amendment to a corporation's articles of incorporation must be approved by the board of directors and by the affirmative vote of holders of at least two-thirds of the outstanding shares entitled to vote, unless the corporation's articles of incorporation provide otherwise. The Midland Charter contains no such provision, therefore, the TBCA provision described above applies to Midland. Vista. Section 242 of the DGCL provides that an amendment to a corporation's certificate of incorporation must be approved by the board of directors and by the affirmative vote of the holders of at least a majority of the outstanding stock entitled to vote thereon. The Vista Charter contains no such provision, therefore, the DGCL provision described above applies to Vista. AMENDMENTS TO BYLAWS Midland. The Midland Bylaws provide that the Midland Bylaws may be altered, amended or repealed, or new bylaws may be adopted, by the Midland Board at any duly held meeting or by the holders of a majority of the shares represented at any duly held meeting of stockholders. Vista. The Vista Bylaws provide that the Vista Bylaws may be amended or repealed, or new bylaws may be adopted, by the affirmative vote of a majority of the directors present at any meeting of the Vista Board at which a quorum is present or by unanimous written consent of all the directors, unless (a) by statute or the Vista Charter the power is reserved exclusively to the stockholders in whole or in part, or (b) the stockholders in amending, repealing or adopting a particular bylaw expressly provide that the Vista Board may not amend or repeal that bylaw. Notwithstanding any provision of law that might otherwise permit lesser or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the capital stock of Vista required by law or by the Vista Charter, the Vista Bylaws shall not be altered, amended or repealed by the stockholders of Vista except in accordance with the Vista Bylaws and by the vote of the holders of not less than a majority in voting power of the outstanding shares of stock then entitled to vote upon the election of directors, voting together as a single class. 119 123 DISSENTERS' RIGHTS Under Texas law, holders of Midland Common Stock will not be entitled to any dissenter's rights in connection with the Merger. Section 5.11 of the Texas Business Corporation Act provides that stockholders have the right to dissent from any plan of merger that requires stockholder approval. Notwithstanding the foregoing, however, Section 5.11 provides that a stockholder shall not have the right to dissent from a plan of merger if (i) the stockholder is not required to accept for the stockholder's shares any consideration that is different from the consideration to be provided to any other stockholder and (ii) the stockholder will receive as consideration shares of stock that are listed, or authorized for listing upon official notice of issuance, on a national securities exchange.

"Bbl" means a barrel of oil and condensate or natural gas liquids. "Bcf" means billion cubic feet of natural gas. "BOE" means one barrel of oil equivalent. "Condensate" means a hydrocarbon mixture that becomes liquid and separates from natural gas when the gas is produced and is similar to crude oil. "Development well" means a well drilled within the proved area of an oil and gas reservoir to the depth of a stratigraphic horizon known to be productive. "Gross," when used with respect to acres or wells, refers to the total acres or wells in which Midland or the Vista Partnership has a working interest. "Infill Drilling" means drilling of an additional well or additional wells in order to more adequately drain a reservoir. "MBbls" means thousands of barrels of oil. "Mcf" means thousand cubic feet of natural gas. "MMBbls" means millions of barrels of oil. "MMBOE" means millions of barrels of oil equivalents. "MMBtu" means one million "British Thermal Units," which means the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit. "MMcf" means million cubic feet of natural gas. "Net," when used with respect to acres or wells, refers to gross acres of wells multiplied, in each case, by the percentage working interest owned by Midland or the Vista Partnership, as the case may be. "Net production" means production that is owned by Midland or the Vista Partnership, as the case may be, less royalties and production due others. "Oil" means crude oil or condensate. "Oil equivalents" means a volume, expressed in Bbls of oil, that includes not only oil but also natural gas and natural gas liquids converted to an equivalent quantity of oil on an energy equivalent basis. Equivalent oil reserves are based on the conversion factor of 6 Mcf of gas per barrel of liquids. "Operator" means the individual or company responsible for the exploration, development and production of an oil or gas well or lease. "Proved developed reserves" means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery will be included as "proved developed reserves" only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved. "Proved reserves" means the estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions (i.e., prices and costs as of the date the 121 125 estimate is made). Prices include consideration of changes in existing prices provided by contractual arrangements, but not on escalation based upon future conditions. i. Reservoirs are considered proved if economic productivity is supported by either actual production or conclusive formation test. The area of a reservoir considered proved includes (A) that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any; and (B) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir. ii. Reserves that can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the "proved" classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based. iii. Estimates of proved reserves do not include the following: (A) oil that may become available from known reservoirs but is classified separately as "indicated additional reserve"; (B) crude oil, natural gas and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics or economic factors; (C) crude oil, natural gas and natural gas liquids that may occur in undrilled prospects; and (D) crude oil, natural gas and natural gas liquids that may be recovered from oil shales, coal, gilsonite and other such sources. "Proved undeveloped reserves" means reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage is limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances are estimates for proved undeveloped reserves attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir. "PV10" means the present value of estimated future revenues to be generated from the production of proved reserves calculated in accordance with Commission guidelines, net of estimated production and future development costs, using prices and costs as of the date of estimation without future escalation, except as otherwise provided by contract, without giving effect to non-property related expenses such as general and administrative expenses, debt service, future income tax expense and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%. "Reserves" means proved reserves. "Royalty" means an interest in an oil and gas lease that gives the owner of the interest the right to receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage. Royalties may be either landowner's royalties, which are reserved by the owner of the leased acreage at the time the lease is granted, or overriding royalties, which are usually reserved by the owner of the leasehold in connection with a transfer to a subsequent owner. "3-D seismic" means seismic data that are acquired and processed to yield a three-dimensional picture of the subsurface. "Working interest" means an interest in an oil and gas lease that gives the owner of the interest the right to drill for and produce oil and gas on the leased acreage and requires the owner to pay a share of the costs of drilling and production operations. The share of production to which a working interest owner is entitled will always be smaller than the share of costs that the working interest owner is required to bear, with the balance of the production accruing to the owners of royalties. For example, the owner of a 100% working interest in a lease burdened only by a landowner's royalty of 12.5% would be required to pay 100% of the costs of a well but would be entitled to retain only 87.5% of the production. 122 126 INDEX TO CONSOLIDATED FINANCIAL STATEMENTS (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED.)

F-28 F-1 127 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS After the conversion transaction discussed in Note 1 to Vista Energy Resources, Inc.'s consolidated financial statements is effected, we expect to be in a position to render the following audit report. To the Board of Directors of Vista Energy Resources, Inc.: We have audited the accompanying consolidated balance sheets of Vista Energy Resources, Inc. as of December 31, 1997 and 1996, and the related consolidated statements of operations, owners' equity, and cash flows for the years ended December 31, 1997 and 1996, and for the period from inception (September 21, 1995), to December 31, 1995. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Vista Energy Resources, Inc. as of December 31, 1997 and 1996, and the results of its operations and its cash flows for the years ended December 31, 1997 and 1996, and for the period from inception (September 21, 1995), to December 31, 1995, in conformity with generally accepted accounting principles.

F-6 132 VISTA ENERGY RESOURCES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1997, 1996, AND 1995 1. ORGANIZATION: Organization Vista Energy Resources, Inc. ("Vista" or the "Company") was incorporated in Delaware in May 1998 for the purpose of consolidating and continuing the activities previously conducted by Vista Resources Partners, L.P., a Texas limited partnership (the "Partnership"). The Partnership was formed on September 21, 1995, for the purpose of acquiring interests in and further developing oil and natural gas properties ("Properties"). Vista Resources I, Inc., a Texas corporation (the "General Partner"), served as the sole general partner of the Partnership. Vista Resources, Inc., a Texas corporation and a wholly owned subsidiary of the Company (the "Operator"), serves as the operator of Properties in which the Company acquires or otherwise owns operating working interests. Pursuant to the terms of an Exchange Agreement dated June 15, 1998 (the "Exchange Agreement"), the Company will acquire all of the outstanding partnership interests of the Partnership and all of the outstanding shares of the General Partner in exchange for shares of Common Stock of the Company (the "Conversion"). The Conversion and other transactions contemplated by the Exchange Agreement will be consummated immediately prior to the closing of the merger (the "Merger") with Midland Resources, Inc. ("Midland"). The Conversion will be accounted for as a transfer of assets and liabilities between affiliates under common control and will result in no change in carrying values of these assets and liabilities. The accompanying consolidated financial statements include the balances and results of operations associated with the Company, the Partnership and its wholly owned subsidiary, Vista Resources, Inc., as of December 31, 1997, and 1996 and for the years ended December 31, 1997 and 1996, and the period from inception (September 21, 1995), to December 31, 1995. All significant intercompany transactions and balances have been eliminated in preparation of the consolidated financial statements. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents All highly liquid investments with original maturities of three months or less are considered to be cash equivalents. Accounts Receivable Trade receivables represent billings to other working interest owners for their share of costs on wells for which the Company serves as the operator. Oil and Gas Properties The Company follows the successful efforts method of accounting for its oil and gas properties whereby costs of productive wells, developmental dry holes, and productive leases are capitalized and amortized on a F-7 133 VISTA ENERGY RESOURCES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) unit-of-production basis over the respective properties' remaining proved reserves. Amortization of capitalized costs of oil and gas properties is provided on a prospect-by-prospect basis. Leasehold costs are capitalized when incurred. Unproved oil and gas properties with significant acquisition costs are periodically assessed and any impairment in value is charged to exploration costs. The costs of unproved properties which are not individually significant are assessed periodically in the aggregate based on historical experience, and any impairment in value is charged to exploration costs. The Company recorded $97,211, $273,843 and $0 of such impairments in 1997, 1996 and 1995, respectively. The costs of unproved properties which are determined to be productive are transferred to proved oil and gas properties. Exploration costs, such as geological and geophysical expenses and annual delay rentals, are charged to expense as incurred. Exploratory drilling costs, if any, including the costs, if any, including the cost of stratigraphic test wells, are initially capitalized but charged to expense if and when the well is determined to be unsuccessful. The Company has adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of." SFAS No. 121 requires that proved oil and gas properties be assessed for an impairment in their carrying value whenever events or changes in circumstances indicate that such carrying value may not be recoverable. SFAS No. 121 requires that this assessment be performed by comparing the future net cash flows and net carrying value of oil and gas properties. This assessment must generally be performed on a property by property basis. No such impairment of the carrying value of oil and gas properties was required in 1997, 1996 or 1995. Other Property and Equipment Other property and equipment are comprised of furniture, fixtures and automobiles. These items are amortized on a straight-line basis over their estimated useful lives, which range from five to seven years. Other Assets Other assets are primarily comprised of organization costs and deferred debt issuance costs and are presented net of accumulated amortization in the financial statements. Organization costs are being amortized on a straight-line basis over five years. Debt issuance costs are amortized over the life of the related debt agreements. Revenue Recognition Policy Revenues are recorded when products have been delivered and services have been performed. The Company uses the sales method to account for gas imbalances. Under this method, revenue is recognized based on the cash received rather than the Company's proportionate share of gas produced. The Company's imbalances at June 30, 1998 and December 31, 1997 and 1996 were not significant. Income Taxes Prior to the Conversion, the results of operations of the Company were included in the tax returns of its owners. As a result, tax strategies were implemented that are not necessarily reflective of strategies the Company would have implemented. In addition, the tax net operating losses generated by the Company during the period from its inception to date of the Conversion will not be available to the Company to offset future taxable income as such benefit accrued to the owners. In conjunction with the Conversion, the Company will adopt SFAS No. 109, "Accounting for Income Taxes," which provides for determining and recording deferred income tax assets or liabilities based on F-8 134 VISTA ENERGY RESOURCES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates. SFAS No. 109 requires that the net deferred tax liabilities of the Company on the date of the Conversion be recognized as a component of income tax expense. The Company will be required to recognize approximately $930,000 in deferred tax liabilities and income tax expense on the date of the Conversion. Upon the Conversion, the Company will become taxable as a corporation. Pro forma income tax information for the years ended December 31, 1997 and 1996 and for the period from inception (September 21, 1995) to December 31, 1995, presented in the accompanying consolidated statements of operations and in Note 7, reflects the income tax expense (benefit) and net income (loss) as if all Partnership income had been subject to corporate federal income tax, exclusive of the effects of recording the Company's net deferred tax liabilities upon the Conversion. Statement of Cash Flows Cash paid for interest for the years ended December 31, 1997 and 1996 and for the period from inception (September 21, 1995) to December 31, 1995 was $702,251, $240,414 and $1,840, respectively. Interim Financial Information In the opinion of the Company, the accompanying consolidated financial statements as of and for the three month periods ended March 31, 1998 and 1997, which have not been audited by independent public accountants, contain all adjustments necessary to present fairly the Company's consolidated financial position, the results of its operations and its cash flows for the periods reported. The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions are eliminated. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. Certain prior amounts have been reclassified to conform to 1998 presentation. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and footnotes thereto included herein. The results of operations for the three months ended March 31, 1998 and 1997 are not necessarily indicative of the results to be expected for a full year. Other Certain amounts in the prior periods' financial statements have been reclassified to conform with the current year presentation. 3. SIGNIFICANT ACQUISITIONS OF OIL AND GAS PROPERTIES AND OTHER ASSETS: 1997 Acquisitions In addition to acquiring various additional small working interests and overriding royalty interests in properties already owned and operated by the Company, the Company closed two significant producing property acquisitions in 1997. In May 1997, the Company acquired all of the interests of Coastal Oil and Gas Corporation in three producing leases located in the Howard Glasscock Field, Howard County, Texas, for a net purchase price of $1,110,920. The interests acquired were attributable to leases in which the Company already owned interests and which were operated by the Operator. Effective as of July 1, 1997, the Company acquired substantially all of the producing oil and gas properties (representing working interests ranging from 25% to 100% in approximately 44 wells located in West Texas, South Texas, East Texas and Southeastern New Mexico) from E.G. Operating, a division of FGL, Inc., for a net purchase price of $6,088,073. All of the Company's 1997 acquisitions were funded through a combination of proceeds from long-term borrowings and cash on hand. F-9 135 VISTA ENERGY RESOURCES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 1996 Acquisitions In addition to acquiring various additional small working interest in oil and gas properties already owned and operated by the Company, the Company closed two significant producing property acquisitions in 1996. Effective as of June 1, 1996, the Company acquired 100% of the working interest in two producing leases (14 wells) located in the Sharon Ridge Field, Scurry County, Texas, for a net purchase price of $446,798. Effective as of July 1, 1996, the Company acquired producing oil and gas properties (representing working interests ranging from 1.4% to 100% in approximately 137 wells located in West Texas and Southeastern New Mexico) from Merit Energy Company and certain of its partnership affiliates for a net purchase price of $4,149,754. All of the Company's 1996 acquisitions were funded through a combination of proceeds from long-term borrowings and cash provided by operating activities. 1995 Acquisitions Effective September 27, 1995, the Company acquired assets comprised primarily of producing oil and gas properties from J. McShane, Inc. and certain of its affiliates and co-working interest owners for total consideration of $7,497,727. The oil and gas assets acquired represent interests in approximately 170 producing wells primarily in the Permian Basin of West Texas and Southeastern New Mexico. The acquisition was funded through a combination of capital contributions and proceeds from long-term borrowings. The 1997, 1996, and 1995 acquisitions were accounted for utilizing the purchase method of accounting. The accompanying consolidated statements of operations include the results of operations from the acquired properties beginning on the dates that the acquisitions were closed. The following table summarizes the unaudited pro forma effect on the Company's consolidated statements of operations as if the acquisitions consummated in 1997 had been closed on January 1, 1997. Future results may differ substantially from pro forma due to changes in prices received for oil and gas sold, production declines and other factors. Therefore, the pro forma amounts should not be considered indicative of future operations. 1997 PRO FORMA ----------- (UNAUDITED) Total Revenues.......................................... $10,265,739 =========== Net Income.............................................. $ 845,212 =========== 4. SALE OF OIL AND GAS PROPERTIES: During 1997, the Company sold certain oil and gas properties for a total net consideration of $390,000, which resulted in a book loss of $87,678. During 1996, the Company sold certain oil and gas properties for total net consideration of $390,371, which resulted in a book loss of $56,738. The Company sold no oil and gas properties in 1995.

LONG-TERM DEBT: As of December 31, 1997, $17,900,000 was outstanding under a $50,000,000 revolving line of credit note (the "Note") with Union Bank of California ("Union Bank") subject to a borrowing base which is redetermined on a semi-annual basis beginning April 1, 1998. The Credit Agreement pursuant to which the Note was originally issued was amended effective as of August 15, 1997 (as further amended from time to time, the "Credit Agreement"), to, among other things, provide for an increase in the facility amount of the Credit Agreement from $15,000,000 to $50,000,000. The borrowing base at December 31, 1997, was $19,000,000. Borrowings under the Note are to be used for the acquisition and development of Properties and for other Company purposes. The Company has two options with respect to interest rate elections on borrowings under the Note. The Company may either elect an interest rate equal to (i) Union Bank's reference rate plus 35 basis points ("Prime Basis") or (ii) a Eurodollar rate (i.e., London Interbank Offered Rate) plus 175 basis points (if amounts outstanding are 50% or less of the then current borrowing base), in either case, as adjusted for Union Bank's Reserve Percentage under Regulation D of the Board of Governors of the Federal Reserve System with respect to Eurocurrency liabilities ("LIBOR Basis"). The LIBOR Basis option provides for one-, two-, three-or six-months periods. At year end the Company had the following amounts outstanding: AMOUNT RATE ELECTION RATE TERM - ------ ------------- ------- -------------------- $4,500,000......................... LIBOR Basis 7.59375% 10/01/97 to 03/31/98 $5,100,000......................... LIBOR Basis 7.65234% 11/29/97 to 05/28/98 $7,900,000.........................

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) As of December 31, 1997, the Company had accrued interest thereunder of $345,758. Unless otherwise extended by Union Bank, the Note converts to a three-year fully amortizing term loan at March 31, 1999. The obligations of the Company under the Credit Agreement and Note are secured by a first lien deed of trust on the Company's interests in certain of its Properties. The Credit Agreement includes covenants which, among other things, restrict the incurrence of additional indebtedness and the sale or acquisition of oil and gas properties above certain levels without the consent of the lender. Effective as of December 23, 1997, the Company entered into an interest rate swap accounted for as a hedge with any realized gains or losses appropriately recorded as interest expense. (See Note 11 for further discussion of hedge accounting.) with Union Bank. The swap consists of $10,000,000 notional amount of indebtedness at a fixed swap rate of 6.021% three month LIBOR for the partnership. The term of this swap ends on December 23, 1999. 7. EMPLOYEE STOCK OPTIONS: Effective September 26, 1995, the Board of Directors of the General Partner adopted the original Option Plan (the "Plan") for certain officers and employees of the Partnership and the Operator. The Plan authorizes the grant of options to acquire units of limited partnership interests in the Partnership ("Units"). Effective April 1, 1997, the Board of Directors of the General Partner amended and restated the Plan in order to provide for additional options to be added to the Plan (the "Amended Plan"). As of December 31, 1997, the Amended Plan provided for future awards of options of up to 165,000 Units. The Amended Plan provides for the issuance of 1,580,321 options in six separate series with an initial exercise price of $1 (series A-D or "$1 options") and $2 (series E-F or "$2 options") which was to be increased 10% per annum from the initial plan adoption date of September 26, 1995, for the $1 options and April 1, 1997, for the $2 options. Option A series, covering 550,358 units, was to vest at a rate of one-third of the options at each of the dates of April 1, 1998, 1999 and 2000. Option B, C, D, and E series were to vest on the dates that the Board determines that the current value of partnership units had increased by a factor of 3, 4, 5, and 6, respectively, or on the date that such per unit amounts of cash or other assets have been or are authorized to be distributed to the partners.

PRICE RISK MANAGEMENT: The Company periodically uses derivative financial instruments to manage crude oil and natural gas price risk. These instruments qualify as hedges under generally accepted accounting principles and are properly recorded as oil and gas sales in the statements of operations. In order to qualify for hedge accounting, each financial instrument must be initially designated as a hedge, must appropriately reduce the price risk and must have correlation to the commodity being hedged. If an instrument does not qualify as a hedge, then it is accounted for as a speculative transaction, with any unrealized gains or losses being reflected in the statement. It is the Company's policy not to engage in speculative transactions of this nature. If a financial instrument designated as a hedge is sold, extinguished or terminated before it matures, then the realized gain or loss is F-14 140 VISTA ENERGY RESOURCES, INC.

OIL AND GAS RESERVES INFORMATION (UNAUDITED): The estimates of proved oil and gas reserves utilized in the preparation of the financial statements were estimated by the Company in accordance with guidelines established by the Securities and Exchange Commission and the Financial Accounting Standards Board, which require that reserve reports be prepared under existing economic and operating conditions with no provision for price and cost escalation except by contractual agreement. All of the Company's reserves are located onshore in or offshore to the continental United States. Future prices received for production and future production costs may vary, perhaps significantly, from the prices and costs assumed for purposes of these estimates. There can be no assurance that the proved reserves will be developed within the periods indicated or that prices and costs will remain constant. There can be no assurance that actual production will equal the estimated amounts used in the preparation of reserve projections. In accordance with the Securities and Exchange Commission's guidelines, the Company's estimates of future net cash flows from the Company's proved properties and the represent value thereof are made using oil and natural gas sales prices in effect as of the dates of such estimates and are held constant throughout the life of the properties. Average prices used in estimating the future net cash flows at December 31, 1997, 1996 and 1995 were as follows: $16.10, $23.55 and $17.49 per barrel for oil in 1997, 1996 and 1995, respectively, and $2.01, $3.43 and $1.84 per Mcf for natural gas in 1997, 1996 and 1995, respectively. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures. oil and gas reserve engineering must be recognized as a subjective process of estimating underground accumulations of oil and gas that cannot be F-15 141 VISTA ENERGY RESOURCES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) measured in an exact way, and estimates of other engineers might differ materially from those shown below. The accuracy of any reserve estimate is a function of the quality of available data and engineering and estimate may justify revisions. Accordingly, reserves estimates are often materially different from the quantities of oil and gas that are ultimately recovered. Reserve estimates are integral in management's analysis of impairments of oil and gas properties and the calculation of depreciation, depletion and amortization on those properties.

F-19 145 E.G. ACQUISITION NOTES TO STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES 1. BASIS OF PRESENTATION: Effective July 1, 1997, Vista Resources Partners, L.P. ("Vista") acquired substantially all of the producing oil and gas properties (representing working interests ranging from 25% to 100% in approximately 44 wells located in West Texas, South Texas, East Texas and Southeastern New Mexico) from E.G. Operating, a division of FGL, Inc., for a net purchase price of $6,088,073. All of Vista's 1997 acquisitions were funded through a combination of proceeds from long-term borrowings and cash on hand. The items of "direct operating expenses" included in the accompanying statements of revenues and direct operating expense include all costs incurred which are necessary for the production, marketing and distribution of the products produced from the subject properties including, without limitation, costs and expenses of field separation; treatment; dehydration; direct overhead charges (other than costs associated with general corporate activities); pumper, roustabout and field supervision labor; meter calibrations; engineering supervision charges; fuel and electricity; valves, connections and other minor equipment repair; oil and lubricants; major repairs (both downhole and surface); rental tools and equipment; pipe inspection; trucking; reservoir testing; pressure testing; well plugging; site remediation; operator bonding; insurance charges; salt water disposal; water injection and pressure maintenance; gas compression; hot oil and hot water treatments; filing fees; make-up water purchases; electrician charges; mud and chemicals; pulling and workover units; other miscellaneous supplies and services; and severance, ad valorem and other production related taxes and charges. The accompanying statements of revenues and direct operating expenses do not include costs associated with general corporate activities, interest income or expense, a provision for depreciation, depletion and amortization or any provision for income taxes because the subject properties acquired by Vista from EG Operating represent only a portion of a business and such items of revenue, income, cost and expense are not necessarily indicative of the costs to be incurred by Vista. Historical financial information reflecting financial position, results of operations and cash flows of the E.G. Acquisition is not presented because the entire acquisition cost was assigned to the oil and gas property interests. Accordingly, the historical statements of revenues and direct operating expenses have been presented in lieu of the financial statements required under Rule 3-05 of Securities and Exchange Commission Regulation S-X. 2. SUPPLEMENTAL OIL AND GAS RESERVE INFORMATION (UNAUDITED): Reserve information presented below has been estimated by Vista's internal engineers using December 31, 1997, prices and costs which were utilized in Vista's reserve estimates as of December 31, 1997. No reserve estimates using assumptions required by the Financial Accounting Standards Board were prepared as of July 1, 1997, by Vista. Proved reserves are estimated quantities of crude oil and natural gas which, based on geologic and engineering data, are estimated to be reasonably recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are those which are expected to be recovered through existing wells with existing equipment and operating methods. Because of inherent uncertainties and the limited nature of reservoir data, such estimates are subject to change as additional information becomes available.

ACQUISITION NOTES TO STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES -- (CONTINUED) Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves The standardized measure of discounted future net cash flows ("Standardized Measure") is prepared using assumptions required by the Financial Accounting Standards Board. Such assumptions include the use of year-end prices for oil and gas and year-end costs for estimated future development and production expenditures to produce year-end estimated proved reserves. Discounted future net cash flows are calculated using a 10% rate. The Standardized Measure does not represent Vista's estimate of future net cash flows or the value of proved oil and gas reserves acquired from E.G. Operating. Probable and possible reserves, which may become proved in the future, are excluded from the calculations. Furthermore, year-end prices, used to determine the standardized measure of discounted cash flows, are influenced by seasonable demand and other factors and may not be the most representative in estimating future revenues or reserve data. As previously stated, Vista used December 31, 1997, pricing and cost information in determining standardized measure at June 30, 1997, as no comparable estimates were available. Prices utilized for the standardized measure at June 30, 1997, were $16.10/Bbl for oil and $2.01/Mcf for gas.

F-27 153 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE A. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Organization and Basis of Presentation Midland Resources, Inc. ("Company"), was organized in 1990 with the issue of common stock and warrants in exchange for oil and gas partnership interests. The Company and its wholly owned subsidiaries are headquartered in Houston, Texas. The Company is involved in the acquisition, exploration, development and production of oil and gas and owns producing properties and undeveloped acreage and royalty interests in Texas, Illinois and Colorado. The majority of its activities are centered in the Permian Basin of West Texas. Midland Resources Operating Company Inc. ("MRO"), a wholly owned subsidiary, is in the business of oil and gas property operations. Summit Petroleum Corporation ("Summit") is a wholly owned subsidiary engaged in oil and gas acquisition, exploration, development and production. (See Note B.) Principles of Consolidation The accompanying consolidated balance sheets include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company balance sheet accounts have been eliminated in consolidation. All significant inter-company transactions have been eliminated from the consolidated statements of operations and cash flows for the years ended December 31, 1997, 1996 and 1995. Reclassifications Certain reclassifications have been made to conform to the 1997 presentation. Oil and Gas Operations The Company follows the "successful efforts" method of accounting for oil and gas properties. All costs associated with the acquisition and development of proved oil and gas properties are capitalized. Costs associated with exploratory drilling are capitalized pending evaluation of drilling results. Costs of exploratory wells which do not find proved results are expensed. Geological, geophysical and delay rental costs are expensed as incurred. Depreciation, depletion and amortization of oil and gas properties is computed on a property-by-property basis using the units-of-production method based upon estimated oil and gas reserve quantities. Oil and gas revenues are recognized under the sales method at the point of delivery to the purchaser. No significant over or under produced positions between the Company and its working interest partners exist. During the fourth quarter of 1995, the Company adopted the provisions of the Financial Accounting Standards Board's Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("FAS 121"). FAS 121 requires impairment losses to be recognized on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by these assets are less than the assets' carrying amount. It also requires assets held for sale to be valued at the lesser of their original carrying amount or fair value. Estimated fair value of oil and gas properties is based on estimates of future net cash flows, discounted at appropriate rates, prepared by independent petroleum engineers. Concurrent with the adoption and decision to market certain oil and gas properties, the Company recognized a write-down of $1,020,670. In 1996 and 1997, the Company recognized losses of $114,904 and $1,277,342, respectively, on its oil and gas properties. In addition, in 1997, the Company recognized abandonment losses of $93,760 resulting from expired and worthless leasehold acreage. F-28 154 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Other Property and Equipment All other property and equipment is depreciated on the straight-line method over lives ranging from 5 to 6 years. Intangible Assets Goodwill is amortized on the straight-line method over 30 years. Property operating contracts are amortized on the straight-line method over the lives of the respective oil and gas properties which range from 3 to 19 years. The carrying amounts and amortization lives of goodwill and property operating contracts are evaluated annually. These costs are combined with net capitalized oil and gas property costs in testing for impairment. Accounting for Stock Options The Company accounts for employee stock option grants in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations, whereby compensation costs are recognized only in situations where stock compensatory plans award intrinsic value to recipients at the date of grant. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The most significant estimates affecting the Company's financial statements are the determination of hydrocarbon reserves, the estimated useful lives of depreciable and amortizable assets, and the fair value of assets held for sale. Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences of differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates applicable to the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Earnings (Loss) Per Common Share Effective December 31, 1997, the Company retroactively adopted the provisions of Statement of Financial Accounting Standards No. 128 for all periods presented. Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during each year. Dilutive earnings per share is calculated by dividing net income by the weighted average number of common and dilutive potential common shares. Stock options and warrants may be potential dilutive common shares and are therefore considered in the earnings per share calculation, if dilutive. The number of dilutive potential common shares is determined using the treasury stock method. Shares used to compute basic and diluted earnings (loss) per share were 4,433,113, 4,395,414 and 3,381,592 in 1997, 1996 and 1995, respectively. Dilutive potential shares (options and warrants) not included in these computations because either their effect was antidilutive, or dilution was immaterial, were 2,754,094, 2,726,022 and 2,572,522 in 1997, 1996 and 1995, respectively. F-29 155 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Employee Benefits Prior to 1995, the Company maintained a 401(k) Plan which covered substantially all full-time employees. In 1995, the Board of Directors authorized the restatement of the plan as the Midland Resources Operating Company, Inc. 401(k) Employee's Stock Ownership Plan and Trust and the contribution of 5,000 shares of treasury stock to the restated plan. An additional 7,300 shares of treasury stock were contributed in 1996. As of December 31, 1995 and 1996, all shares had been allocated to participants in the plan. The Company matches employee contributions up to 3 percent of gross salary. The expense related to the Company's contributions and plan administration was $26,517, $50,092, and $25,985 in 1997, 1996 and 1995, respectively. Financial Instruments The carrying amount of cash approximates fair value. Interest rates associated with substantially all the Company's long-term debt are linked to current market rates. As a result, management believes that the carrying amount approximates the fair value of the Company's credit facilities. Interim Financial Statements The financial statements as of June 30, 1998 and 1997 and for the six month periods then ended, included herein, are unaudited. These financial statements include all adjustments, (consisting only of normal recurring adjustments), which are, in the opinion of management, necessary for a fair presentation of the financial statements for these periods. The results of operations for these three month periods are not necessarily indicative of the results for a full year. NOTE B. PURCHASE OF SUBSIDIARY CORPORATION On September 18, 1996, the Company, through MRI Acquisition Corp. (a wholly owned subsidiary), acquired 81.5% of the issued and outstanding common stock and all outstanding stock options of Summit Petroleum Corporation (See Note F.) for cash of $1,081,188 and cancellation of a note receivable from an officer/stockholder of both the Company and Summit of $479,648. In December 1996, the Summit stockholders approved a plan of merger whereby Summit became a wholly owned subsidiary of the Company. Pursuant to this plan, stockholders possessing the remaining 18.5% interest (443,633 shares), upon tendering their shares, receive $0.70 per share. During 1997, payments of $89,139 were made for 127,341 shares tendered. The Company's liability for the purchase of these remaining shares, which is being funded through long-term borrowings under the Company's revolving credit agreement (See Note C.), is included as a non- current liability in the accompanying balance sheet. The purchase price ($0.70 per share and $0.6375 per option) was based on the fair value of Summit's net assets as determined by the Board of Directors of each respective corporation. The transaction was subject to a fairness opinion provided by a recognized investment banking firm relative to these values. In addition to the purchase price, the Company incurred $139,254 in costs directly related to this acquisition, resulting in a total investment through December 31, 1997, of $2,010,633. This acquisition is accounted for under the purchase method of accounting, which provides that the results of operations are combined from the date of acquisition (September 18, 1996). In December 1996, MRI Acquisition Corp. was dissolved and Summit became a wholly-owned subsidiary of the Company. F-30 156 MIDLAND RESOURCES, INC.

Concurrent with the execution of this agreement, the Company's outstanding debt to First Union National Bank (FUNB) in the amount of $9,151,615 was paid by an advance under the Compass agreement. Amounts borrowed under the Compass agreement are collateralized by a first lien on substantially all of the Company's oil and gas properties. Interest under this agreement is payable monthly at an annual rate which, at the Company's option, is equal to either (a) the Compass prime lending rate (8.5% at December 31, 1997) or (b) the London Interbank Offered Rate, plus 2.5%. In addition, a commitment fee equal to 1/2% per annum on the unused portion of the borrowing base is required. The borrowing base is reduced at the rate of $120,000 per F-31 157 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) month beginning February 1, 1998 and is subject to redetermination on each April 1st and October 1st. This agreement also requires that the Company maintain certain financial ratios and generally restricts the Company's ability to incur debt, sell assets, materially change the nature of the Company's business structure or pay dividends. Future maturities of long term debt at December 31, 1997 are as follows: 1998..................................................... $ 583,481 1999..................................................... 9,100,918 2000..................................................... 11,083 2001..................................................... 3,369 ---------- $9,698,851 ========== NOTE D. ISSUANCE OF COMMON STOCK AND WARRANTS In November 1990, the Company issued 2,264,522 shares of common stock, as discussed in Note A, based on an exchange value of $2.00 per share. For each share of common stock issued, two warrants were issued entitling the holder to purchase one share of common stock at $2.50 and one share at $4.00 during the period from November 1990 to November 2002. On October 6, 1995, the 90 day common stock market price requirement (as defined in the Warrant Agreement) was met and the Company called its $2.50 warrants. Holders of record on December 22, 1995 received a redemption payment of $0.05 per warrant for aggregate payments of $63,373, which was charged to additional paid in capital. 997,009 of the $2.50 warrants were exercised. As of December 31, 1997, 11,428 of the $4.00 warrants had been exercised. The warrants are subject to certain antidilution provisions contained in the warrant agreement, which could cause adjustments to the exercise price and the number of shares issuable. The Company has two employee stock option plans which reserve an aggregate of 700,000 shares of common stock for issuance to officers and other key employees. As of December 31, 1997 options to acquire 260,000 shares at prices ranging from $2.375 to $4.00 were outstanding under these plans with scheduled expiration dates of 1998 through 2002. As of December 31, 1997, 376,500 shares were available for future grant. Under the Midland Resources, Inc. 1995 Directors' Stock Option Plan, 20,000 stock options with a five year term were granted to directors in 1995. As of December 31, 1995, all 20,000 options were outstanding under this plan. In 1996, an additional 30,000 stock options were granted to directors. Each option entitles the holder to purchase one share of common stock for the fair market value of common stock on the date of the grant of the option. As of December 31, 1997, 50,000 options were outstanding under this plan at exercise prices ranging from $2.75 to $3.75 and 50,000 options were available for future grant. Options outstanding at December 31, 1997, if not exercised, are scheduled to expire in 1999 through 2001. In May 1997, the Stockholders ratified the Midland Resources, Inc. 1997 Board of Directors Stock Incentive Plan under which 1,000,000 options were issued to non-employee directors, 175,000 options were issued to the advisory director and 60,000 were issued to the corporate secretary, all to acquire shares at $3.00 per share. These options are vested as certain stipulated trading prices for the Company's common stock are achieved and, exercisability is further restricted by time delay provisions which limited the number of vested shares that may be exercised each year beginning in March 1998. As of December 31, 1997, 247,000 of these options were vested. Upon a change of control, as defined, all of these options became exercisable. These options, if not exercised, expire in March, 2002. Also in February, 1997, the Company issued a five year warrant to purchase 50,000 shares to a consultant for future services. These options and warrants are expected to give rise to the recognition of compensation expenses of up to $616,250 through year 2000. In 1997, stock-based compensation expense of $217,484 was recognized in connection with these issuances. F-32 158 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) In June 1995, the Company issued 150,000 warrants to purchase common stock at $4.00 per share for a term of seven years to FUNB. In exchange the Company's credit facility loan agreement was amended to reduce the interest rate by 0.75% and allow 25% of its borrowing base to be used for working capital purposes. The fair value of the warrants at the date of grant was recorded as debt discount and additional paid in capital. None of these warrants have been exercised as of December 31, 1997. Warrants to purchase an additional 70,000 shares of common stock were issued in 1994 through 1996 in exchange for investment banking and other services, with exercise prices ranging from $2.50 to $2.875. Effective January 1, 1996, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123, which provides for an alternative method to valuation of the compensation element of stock based compensation plans. The Company applies APB 25 and related Interpretations in accounting for employee stock-based compensation. Had compensation costs been determined based on the fair value at the grant dates for awards consistent with the method of FASB Statement 123, the Company's net income (loss) and related per share amounts would have been reduced to the pro forma amounts indicated below: 1997 1996 1995 ----------- --------- --------- Net income (loss): As reported.................................... $(1,883,382) $ 22,122 $(737,031) Pro forma......................................

MAJOR CUSTOMERS The Company and its subsidiaries operate exclusively within the United States and their revenues and operating income are derived predominately from the oil and gas industry. Oil and gas production is sold to various purchasers and the receivables are generally uncollateralized. The Company has not experienced significant credit losses on its oil and gas accounts and management is of the opinion that significant credit risk does not exist. Management is of the opinion that the loss of any one purchaser would not have an adverse effect on the ability of the Company to sell its oil and gas production. In 1997, three purchasers accounted for 18%, 15% and 12%, respectively, of total oil and gas revenues. In 1996, three purchasers accounted for 18%, 12% and 15%, respectively, of total oil and gas revenues. In 1995, four purchasers accounted for 18%, 17%, 11% and 11%, respectively, of total oil and gas revenues. NOTE F. RELATED PARTIES Until December 1993, MRO was owned 80% by the Company's then President and Chairman of the Board of Directors, Mr. Deas H. Warley III and 20% by a former Vice President and Board Member, Sal J. F-35 161 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Pagano. Mr. Warley currently owns approximately 16% of the Company's outstanding common stock and 5% of the related $4.00 warrants. Effective November 1, 1995, the Company purchased a building and land in Midland County, Texas, for $78,996 from Mr. Warley and another individual for use as a district office. Mr. Warley and the other individual each financed 50% of the purchase price less the down payment of $10,496. The two $34,250 ten year notes bore interest at 7.5% and were payable in equal monthly installments of $407 each. The cost to the Company was based on an independent written appraisal and certain improvements completed before the property was purchased. This property was sold in 1997 at a gain of $46,500. In December 1995, Mr. Warley borrowed $582,805 from the Company under an eighteen month term note bearing 7.5% interest, secured by 287,947 shares of the Company's common stock. Mr. Warley used these funds to exercise his 233,122 warrants to buy common stock at $2.50 per share. The balance of the note payable to Mr. Warley discussed above was netted against this note receivable and he made a cash payment of $95,000 leaving a balance of $453,641 at December 31, 1995. This amount was reflected in the financial statements as a reduction of stockholders' equity at December 31, 1995. This note was paid in full in September 1996 by offsetting the balance of $479,648 against the payment to Mr. Warley for his stock and options in Summit Petroleum Corporation (See Note B.). During 1995, Summit participated with the Company in the acquisition of certain oil and gas leases and seismic options in the Sunburst Project, Terry County, Texas, and the Latigo and Lakota Projects, Hockley County, Texas in exchange for a commitment from the Company and Summit to expend certain monies in connection with acquiring an interest in certain oil and gas leases, seismic options, conducting 3-D geological surveys, interpretation of 3-D seismic data and the drilling of two or more test wells. Summit acquired its five percent interest working interest in proportion to its share of the commitment. Effective September 1, 1995, Summit participated with the Company in the acquisition of additional working interests in certain Redfish Bay properties in Nueces County, Texas. Summit acquired its four percent working interest on the same basis as the Company. The amounts due from a related party at December 31, 1996, represents reimbursements due for certain acquisition and exploration costs from a limited partnership, formed in January, 1997, for which the Company served as general partner. Amounts due from a related party at December 31, 1997 represents amounts due from this partnership for property operations and drilling costs. The limited partnership group was initially comprised of 19 individuals of which 18 were also stockholders of the Company. In addition, two of these individuals are directors of the Company. During 1997, the Company's interest was assigned to the Company in the form of oil and gas property interests and, effective December 31, 1997 the Company withdrew from the partnership. During 1997, the Company acquired working interests from two directors and a partnership interest from one of these directors for cash consideration of $144,879 and 15,040 shares of common stock valued at $52,625. NOTE G. COMMITMENTS AND CONTINGENCIES The Company is involved in litigation arising in the ordinary course of business. Management believes the ultimate resolution of these matters will not have a material effect on the consolidated financial statements (see Note N.). F-36 162 MIDLAND RESOURCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The Company leases its executive office space and a field office under noncancellable operating leases expiring in 2002. Rental expense was $34,560 in 1995, $92,088 in 1996, and $93,988 in 1997. Future minimum rental commitments, as of December 31, 1997, for these leases are as follows: 1998..................................................... $117,216 1999..................................................... 117,216 2000..................................................... 117,216 2001..................................................... 117,216 2002..................................................... 78,144 -------- $547,008 ======== NOTE H.

Management has determined that, based on future expectations, it is more likely than not that the Company's future taxable income will be sufficient to fully utilize these losses prior to their expiration. In addition, the Company has losses of approximately $610,000 which, if not utilized, will begin to expire in 1998. Management has determined that, based on future expectations, it is more likely than not, that approximately $431,000 of this amount will not be utilized and, accordingly, has established a valuation allowance.

HEDGING ACTIVITIES Effective March 1, 1995, the Company entered into a one year gas swap agreement to hedge against a portion of the price risk associated with gas price declines. This agreement covers approximately 50% of the Company's total estimated gas production. The Company's price under this agreement is a minimum of $1.50 per Mcf with a 40% participation in prices over $1.50. This swap agreement expired in February, 1996, and the Company has not entered into another contract. Losses under this contract were $21,109 and $25,860 for 1995 and 1996, respectively. Gains or losses relating to the swap agreement are measured, settled and recognized at the end of each month as part of oil and gas sales. NOTE K.

SUBSEQUENT EVENT (SECOND PARAGRAPH IS UNAUDITED) On April 9, 1998, The Board of Directors approved a plan to combine with Vista Resources Partners, L.P., a Midland, Texas based entity engaged in oil and gas exploration and production. Consummation of any transaction pursuant to these negotiations depends upon the satisfaction or waiver of a number of conditions, including, without limitation, stockholder approval, execution of a definitive agreement and receipt of a fairness opinion. The Company has been involved in pending litigation, the nature of which is a claim for damages arising from the Company's actions as operator of certain properties in which the plaintiff has an interest, and removal of the Company as operator of the properties. The plaintiff had not specified a damage amount until subsequent to April 1998, at which time damages of $230,000 were claimed. The Company has filed a counterclaim against the plaintiff. Management believes the ultimate resolution of this matter will not have a material adverse effect on the Company.

At the Effective Time, without any action on the part of any party hereto, each issued and outstanding share of GP Common Stock held by a Holder shall be exchanged for a number of shares of Common Stock equal to 1.60089817 (the "Vista GP Conversion Stock Number") and a Newco Warrant that is exercisable for a number of shares of Common Stock equal to 1.16511028 (the "Vista GP Conversion Warrant Number") and each issued and outstanding Partnership Interest that is held by a Holder shall be exchanged for a number of shares of Common Stock equal to 117,674.06 (the "Vista LP Conversion Stock Number") and a Newco Warrant that is exercisable for a number of shares of Common Stock equal to 85,641.46 (the "Vista LP Conversion Warrant Number").

As provided in the Merger Agreement, each of the Vista GP Conversion Stock Number, the Vista LP Conversion Stock Number, the Vista GP Conversion Warrant B-1 236 Number and the Vista LP Conversion Warrant Number shall be increased or decreased, as necessary, immediately prior to the Effective Time such that (i) the aggregate percentage of shares of Common Stock that the Holders of GP Common Stock and the Holders of Partnership Interests shall be entitled to receive at the Effective Time shall equal 72.5% of the shares of Common Stock that will be outstanding calculated on a Fully Diluted Basis immediately after the Effective Time and (ii) the aggregate percentage of shares of Newco Common Stock issuable upon exercise of the Newco Warrants that the Holders of GP Common Stock and the Holders of Partnership Interests shall be entitled to receive shall equal 72.5% of the shares of Common Stock that is issuable upon the exercise of (x) all of the Midland Warrants outstanding immediately after the Effective Time, (y) all Newco Warrants issued pursuant to the Midland Exchange and (z) all Newco Warrants issuable pursuant to the Vista Exchange. Subject to Section 1.3, any such adjustments to the Vista GP Conversion Stock Number, the Vista LP Conversion Stock Number, the Vista GP Conversion Warrant Number or the Vista LP Conversion Warrant Number shall be made not later than two business days prior to the Closing and shall be determined by Newco's independent auditors Arthur Andersen LLP. 1.2 EXCHANGE OF GP COMMON STOCK CERTIFICATES. (a) EXCHANGE FUND. Immediately after the Effective Time, the Company shall deposit with the Exchange Agent, for the benefit of the Holders of GP Common Stock and Partnership Interest and for exchange in accordance with this Agreement, (i) certificates representing the shares of Common Stock and (ii) certificates representing the Newco Warrants, in each case to be issued in exchange for shares of GP Common Stock and Partnership Interest pursuant to Section 1.1. Such shares of Common Stock and Newco Warrants, together with any dividends or distributions with respect thereto (as provided in subsection (c) of this Section 1.2), are referred to herein as the "Exchange Fund." The Exchange Agent, pursuant to irrevocable instructions consistent with the terms of this Agreement, shall deliver the Common Stock and Newco Warrants to be issued pursuant to Section 1.1 out of the Exchange Fund, and the Exchange Fund shall not be used for any other purpose. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect thereto for the account of any Person thereto. (b) EXCHANGE PROCEDURES FOR GP COMMON STOCK. (i) As soon as reasonably practicable after the Effective Time, the Company shall cause the Exchange Agent to mail to each holder of record of a certificate representing shares of GP Common Stock (a "GP Certificate") that, immediately prior to the Effective Time, represented shares of GP Common Stock converted into Common Stock and Newco Warrants pursuant to Section 1.1 a letter of transmittal to be used to effect the exchange of such GP Certificate for a certificate representing shares of Common Stock (a "Company Certificate") and a certificate representing a Newco Warrant (a "Warrant Certificate"), along with instructions for using such letter of transmittal to effect such exchange. The letter of transmittal (or the instructions thereto) shall specify that delivery of any GP Certificate shall be effected, and risk of loss and title thereto shall pass, only upon delivery of such GP Certificate to the Exchange Agent and shall be in such form and have such other provisions as the Company may reasonably specify. (ii) Upon delivery to the Exchange Agent of, together with the surrender of a GP Certificate, if applicable, a duly completed and executed letter of transmittal and any other required documents, (A) the Holder of such GP Certificate shall be entitled to receive in exchange therefor (x) a Company Certificate representing the number of shares of Common Stock that such Holder has the right to receive pursuant to Section 1.1 and any unpaid dividends and distributions that such Holder has the right to receive pursuant to subsection (d) of this Section (after giving effect to any required withholding of taxes) and (y) a Warrant Certificate exercisable for a number of shares of Common Stock that such Holder has the right to receive pursuant to Section 1.1, and (B) the GP Certificate, if any, so surrendered shall forthwith be cancelled. No interest shall be paid or accrued on unpaid dividends and distributions, if any, payable to Holders of GP Certificates. B-2 237 (iii) In the event of a transfer of ownership of GP Common Stock that is not registered in the transfer records of the General Partner, a Company Certificate and Warrant Certificate representing the appropriate number of shares of Common Stock may be issued to a transferee if the GP Certificate representing such shares of GP Common Stock is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. (iv) Until surrendered as contemplated by this subsection, each GP Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender a Company Certificate and Warrant Certificate as provided in this Agreement. (c) EXCHANGE PROCEDURES FOR PARTNERSHIP INTEREST. (i) The parties hereby acknowledge and agree that the Partnership Interest are uncertificated and that the ownership of the Partnership Interest is evidenced by the records of Vista and that such ownership is reflected on Exhibit A hereto. As soon as reasonably practicable after the Effective Time, the Company shall deliver to the Exchange Agent a letter of instruction, directing the Exchange Agent to issue to each Holder, who has executed and delivered a counterpart of this Agreement, (x) a Company Certificate representing the number of shares of Common Stock that such Holder has the right to receive pursuant to Section 1.1 and any unpaid dividends and distributions that such Holder has the right to receive pursuant to subsection (d) of this Section (after giving effect to any required withholding of taxes) and (y) a Warrant Certificate exercisable for a number of shares of Common Stock that such Holder has the right to receive pursuant to Section 1.1.

(d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other distributions with respect to Common Stock declared or made after the Effective Time with a record date after the Effective Time shall be paid to the Holder of any unsurrendered GP Certificate or Partnership Interest prior to delivery of the exchange instructions by the Company. Subject to the effect of applicable laws, (i) at the time of the surrender of a GP Certificate for exchange in accordance with the provisions of this Section or the delivery of the applicable exchange instructions in the case of the Partnership Interest, there shall be paid to the Holder thereof, without interest, the amount of dividends or other distributions (having a record date after the Effective Time but on or prior to surrender and a payment date on or prior to surrender) theretofore paid with respect to the number of shares of Common Stock that such Holder is entitled to receive (less the amount of any withholding taxes that may be required with respect thereto) and (ii) at the appropriate payment date, there shall be paid to the Holder, without interest, the amount of dividends or other distributions (having a record date after the Effective Time but on or prior to surrender and a payment date subsequent to surrender) payable with respect to the number of shares of Common Stock that such Holder receives (less the amount of any withholding taxes that may be required with respect thereto). (e) NO FURTHER OWNERSHIP RIGHTS. The shares of Common Stock and Newco Warrants issued in exchange of shares of GP Common Stock and Partnership Interest in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights of the Holders pertaining to such shares of GP Common Stock and Partnership Interest. (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund held by the Exchange Agent in accordance with the terms of this Section that remains unclaimed by a Holder for a period of one year following the Effective Time shall be delivered to the Company, upon demand. Thereafter, a Holder who has not theretofore complied with the provisions of this Section shall look only to the B-3 238 Company for their claim for Common Stock and any dividends or distributions with respect to Common Stock (all without interest and Newco Warrants). (g) NO LIABILITY. None of the Company, the General Partner, the Exchange Agent, or any other Person shall be liable to any Holder for any amount properly delivered to any public official pursuant to any applicable abandoned property, escheat, or similar law. Any amounts remaining unclaimed by Holders for a period of two years following the Effective Time (or such earlier date immediately prior to the time at which such amounts would otherwise escheat to or become property of any governmental entity) shall, to the extent permitted by applicable law, become the property of the Company free and clear of any claims or interest of any such Holders or their successors, assigns, or personal representative previously entitled thereto. (h) LOST, STOLEN, OR DESTROYED GP CERTIFICATES. If any GP Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the Person claiming such GP Certificate to be lost, stolen, or destroyed and, if required by the Company, the posting by such Holder of a bond in such reasonable amount as the Company may direct as an indemnity against any claim that may be made against it with respect to such GP Certificate, the Exchange Agent shall issue in exchange for such lost, stolen, or destroyed GP Certificate the shares of Common Stock (along with any unpaid dividends and distributions pursuant to subsection (c) of this Section) deliverable with respect thereto pursuant to this Agreement. 1.3 POST-EFFECTIVE TIME ADJUSTMENT. Effective as of the last day of the fourth calendar month immediately following the calendar month in which the Closing Date occurred, Newco shall cause its independent auditors Arthur Andersen LLP to redetermine the Vista GP Conversion Stock Number and the Vista LP Conversion Stock Number by redetermining, as of such date, Fully Diluted Basis to the extent necessary so as to reflect the number of shares of Newco Common Stock, if any, issued after the Effective Time as of the result of the exercise of any Midland Stock Options. In the event any such adjustment to the Vista GP Conversion Stock Number and the Vista LP Conversion Stock Number is determined appropriate, then Newco shall promptly issue to each Holder such Holder's pro rata share of a number of shares of Newco Common Stock equal to an amount equal to (i) the quotient realized by dividing (x) the number of shares of Newco Common Stock issued after the Effective Time as a result of the exercise of any Midland Stock Options by (y) .275 minus (ii) the number of shares of Newco Common Stock described in clause (x) above.

At the Effective Time, without any action on the part of any party hereto, each Midland Exchange Stock Option shall be exchanged for a Newco Warrant that is exercisable for that whole number of shares of Common Stock (to the nearest whole share) equal to the product of (x) .725 times (y) the number of shares of Newco Common Stock into which the shares of Midland Common Stock subject to such Midland Exchange Stock Option would be converted pursuant to the terms of the Merger Agreement. No payment shall be made for fractional interests. 1.2 EXCHANGE OF MIDLAND EXCHANGE STOCK OPTIONS. (a) EXCHANGE FUND. Immediately after the Effective Time, the Company shall deposit with the Exchange Agent, for the benefit of the Holders and for exchange in accordance with this Agreement, certificates representing the Newco Warrants to be issued in exchange for Midland Exchange Stock Options pursuant to Section 1.1. Such Newco Warrants, together with any dividends or distributions with respect thereto (as provided in subsection (c) of this Section 1.2), are referred to herein as the C-1 246 "Exchange Fund." The Exchange Agent, pursuant to irrevocable instructions consistent with the terms of this Agreement, shall deliver the Newco Warrants to be issued pursuant to Section 1.1 out of the Exchange Fund, and the Exchange Fund shall not be used for any other purpose. (b) EXCHANGE PROCEDURES FOR MIDLAND EXCHANGE STOCK OPTIONS. (i) As soon as reasonably practicable after the Effective Time, the Company shall cause the Exchange Agent to mail to each Holder a letter of transmittal to be used to effect the exchange of such Holder's Midland Exchange Stock Options for a certificate representing a Newco Warrant (a "Warrant Certificate"), along with instructions for using such letter of transmittal to effect such exchange. The letter of transmittal (or the instructions thereto) shall specify that delivery of such Holder's Midland Exchange Stock Options shall be effected, and risk of loss and title thereto shall pass, only upon delivery of such Holder's Midland Exchange Stock Options to the Exchange Agent and shall be in such form and have such other provisions as the Company may reasonably specify. (ii) Upon delivery to the Exchange Agent of, together with the surrender of a Holder's Midland Exchange Stock Options, if applicable, a duly completed and executed letter of transmittal and any other required documents, the Holder of such Exchange Stock Options shall be entitled to receive in exchange therefor a Warrant Certificate exercisable for a number of shares of Common Stock that such Holder has the right to receive pursuant to Section 1.1. (iii) From and after the Effective Time, each Midland Exchange Stock Option shall be deemed to represent only the right to receive a Warrant Certificate as provided in this Agreement. (c) NO FURTHER OWNERSHIP RIGHTS. The Newco Warrants issued in exchange of Midland Exchange Stock Options in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights of the Holders pertaining to such Midland Exchange Stock Options. Each Midland Exchange Stock Option shall be terminated immediately following their exchange for a Newco Warrant. (d) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund held by the Exchange Agent in accordance with the terms of this Section that remains unclaimed by a Holder for a period of one year following the Effective Time shall be delivered to the Company, upon demand. Thereafter, a Holder who has not theretofore complied with the provisions of this Section shall look only to the Company for their claim for Newco Warrants. (e) NO LIABILITY. None of the Company, the General Partner, the Exchange Agent, or any other Person shall be liable to any Holder for any amount properly delivered to any public official pursuant to any applicable abandoned property, escheat, or similar law. Any amounts remaining unclaimed by Holders for a period of two years following the Effective Time (or such earlier date immediately prior to the time at which such amounts would otherwise escheat to or become property of any governmental entity) shall, to the extent permitted by applicable law, become the property of the Company free and clear of any claims or interest of any such Holders or their successors, assigns, or personal representative previously entitled thereto.

The Director Options are being restructured (the "Restructuring") into a restricted version of the current issue of Class B Warrants of Midland (the "Director Warrants"). You have requested that we render our opinion as to whether the Restructuring is fair from a financial point of view to the holders of the currently outstanding Midland Common Stock. Dain Rauscher Wessels, a division of Dain Rauscher Incorporated ("Dain Rauscher Wessels"), as part of its investment banking services, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, corporate restructurings, negotiated underwritings, secondary distributions of listed and unlisted securities private placements and valuations for corporate and other purposes.

We have, among other things: (i) reviewed the Stock Option Agreement; (ii) reviewed the 1997 Board of Directors Stock Incentive Plan; (iii) reviewed the Warrant Agreement; (iv) reviewed the Registration Rights Agreement for Midland Holders; and (v) reviewed publicly available financial data and stock market performance data of Midland Common Stock as well as the publicly traded Class B Warrants.

Based on the current price levels of Midland Common Stock, application of the Black-Scholes option pricing model, the restrictions on the new Director Warrants and an overall business judgment, an exchange ratio of 0.725 new Director Warrants for one Director Option is fair as of the date hereof from a financial point of view to the holders of the currently outstanding Midland Common Stock.

Vista Energy Resources, Inc., a Delaware corporation (herein, together with its successors, referred to as the "Company"), by means of this 1998 Stock Option Plan (the "Plan"), desires to afford certain individuals and key employees of the Company and any parent corporation or subsidiary corporation thereof now existing or hereafter formed or acquired (such parent and subsidiary corporations sometimes referred to herein as "Related Entities") who are responsible for the continued growth of the Company an opportunity to acquire a proprietary interest in the Company, and thus to create in such persons an increased interest in and a greater concern for the welfare of the Company and any Related Entities. As used in the Plan, the terms "parent corporation" and "subsidiary corporation" shall mean, respectively, a corporation within the definition of such terms contained in Sections 424(e) and 424(f), respectively, of the Internal Revenue Code of 1986, as amended (the "Code"). The stock options described in Sections 6 and 7 (the "Options"), and the shares of Common Stock (as hereinafter defined) acquired pursuant to the exercise of such Options are a matter of separate inducement and are not in lieu of any salary or other compensation for services. 2. ADMINISTRATION. (a) COMMITTEE. The Board of Directors of the Company (the "Board of Directors" shall administer the Plan with respect to all Key Employees (as hereinafter defined) or Eligible Non-Employees (as hereinafter defined) or may delegate all or part of its duties under this Plan to any committee appointed by the Board of Directors (the "Committee") or to any officer or committee of officers of the Company, subject in each case to such conditions and limitations as the Board of Directors may establish and subject to the following sentence. Unless a majority of the members of the Board of Directors determines otherwise: (a) the Committee shall be constituted in a manner that satisfies the requirements of Rule 16b-3, which Committee shall administer the Plan with respect to all Key Employees or Eligible Non-Employees who are subject to Section 16 of the Exchange Act in a manner that satisfies the requirements of Rule 16b-3; and (b) the Committee shall be constituted in a manner that satisfies the requirements of Section 162(m), which Committee shall administer the Plan with respect to "performance-based compensation" for all Key Employees or Eligible Non-Employees who are reasonably expected to be "covered employees" as those terms are defined in Section 162(m). The number of persons that shall constitute the Committee shall be determined from time to time by a majority of all the members of the Board of Directors. Except for references in Sections 2(a), 2(b), and 2(c) and unless the context otherwise requires, references herein to the Committee shall also refer to the Board of Directors as administrator of the Plan for Key Employees or Eligible Non-Employees or to the appropriate delegate of the Committee or the Board of Directors. (b) DURATION, REMOVAL, ETC. The members of the Committee shall serve at the pleasure of the Board of Directors, which shall have the power, at any time and from time to time, to remove members from or add members to the Committee. Removal from the Committee may be with or without cause. Any individual serving as a member of the Committee shall have the right to resign from membership in the Committee by written notice to the Board of Directors. The Board of Directors, and not the remaining members of the Committee, shall have the power and authority to fill vacancies on the Committee, however caused. (c) MEETINGS AND ACTIONS OF COMMITTEE. The Board of Directors shall designate which of the Committee members shall be the chairman of the Committee. If the Board of Directors fails to designate a Committee chairman, the members of the Committee shall elect one of the Committee members as chairman, who shall act as chairman until he ceases to be a member of the Committee or until the Board E-1 259 of Directors elects a new chairman. The Committee shall hold its meetings at those times and places as the chairman of the Committee may determine. At all meetings of the Committee, a quorum for the transaction of business shall be required, and a quorum shall be deemed present if at least a majority of the members of the Committee are present. At any meeting of the Committee, each member shall have one vote. All decisions and determinations of the Committee shall be made by the majority vote or majority decision of all of its members present at a meeting at which a quorum is present; provided, however, that any decision or determination reduced to writing and signed by all of the members of the Committee shall be as fully effective as if it had been made at a meeting that was duly called and held. The Committee may make any rules and regulations as it may deem advisable for the conduct of its business that are not inconsistent with the provisions of the Plan, the certificate of incorporation of the Company, the by-laws of the Company, Rule 16b-3 so long as it is applicable, and Section 162(m) so long as it is applicable. 3. SHARES AVAILABLE. Subject to the adjustments provided in Section 10, the maximum aggregate number of shares of Common Stock, $.01 par value, of the Company ("Common Stock") in respect of which Options may be granted for all purposes under the Plan shall be 900,000 shares. If, for any reason, any shares as to which Options have been granted cease to be subject to purchase thereunder, including the expiration of such Option, the termination of such Option prior to exercise, or the forfeiture of such Option, such shares shall thereafter be available for grants under the Plan. Options granted under the Plan may be fulfilled in accordance with the terms of the Plan with (i) authorized and unissued shares of the Common Stock, (ii) issued shares of such Common Stock held in the Company's treasury, or (iii) issued shares of Common Stock reacquired by the Company in each situation as the Board of Directors or the Committee may determine from time to time. 4. ELIGIBILITY AND BASES OF PARTICIPATION. Grants of Incentive Options (as hereinafter defined) and Non-Qualified Options (as hereinafter defined) may be made under the Plan, subject to and in accordance with Section 6, to Key Employees. As used herein, the term "Key Employee" shall mean any employee of the Company or any Related Entity, including officers and directors of the Company or any Related Entity who are also employees of the Company or any Related Entity, who is regularly employed on a salaried basis and who is so employed on the date of such grant, whom the Committee identifies as having a direct and significant effect on the performance of the Company or any Related Entity. Grants of Non-Qualified Options may be made, subject to and in accordance with Section 7, to any Eligible Non-Employee. As used herein, the term "Eligible Non-Employee" shall mean any person or entity of any nature whatsoever, specifically including an individual, a firm, a company, a corporation, a partnership, a trust, or other entity (collectively, a "Person"), that the Committee designates as eligible for a grant of Options pursuant to this Plan because such Person performs bona fide consulting, advisory, or other services for the Company or any Related Entity (other than services in connection with the offer or sale of securities in a capital-raising transaction) and the Board of Directors or the Committee determines that the Person has a direct and significant effect on the financial development of the Company or any Related Entity. The adoption of this Plan shall not be deemed to give any Person a right to be granted any Options. Notwithstanding any other provision of this Plan to the contrary, with respect to the grant of any Options to any Key Employee or Eligible Non-Employee, the Committee shall first determine the number of shares in respect of which Options are to be granted to such Key Employee or Eligible Non-Employee and shall then cause to be granted to such Key Employee or Eligible Non-Employee an Option exercisable for such shares. The exercise price per share of Common Stock under each Option shall be fixed by the Committee at the time of grant of the Option and shall equal at least 100% of the Fair Market Value of a share of Common Stock on the date of grant.

The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, in any Option, or in any awards evidencing Options granted hereunder in the manner and to the extent it deems necessary or desirable to carry the Plan into effect, and the Committee shall be the sole and final judge of that necessity or desirability.

Each Option accelerated by the Committee pursuant to the preceding sentence shall terminate, notwithstanding any express provision thereof or any other provision of the Plan, on such date (not later than the stated exercise date) as the Committee shall determine. 9. ADJUSTMENT OF SHARES. Unless otherwise expressly provided in a particular Option, in the event that, by reason of any merger, consolidation, combination, liquidation, reorganization, recapitalization, stock dividend, stock split, split-up, split-off, spin-off, combination of shares, exchange of shares or other like change in capital structure of the Company (collectively, a "Reorganization"), the Common Stock is substituted, combined, or changed into any cash, property, or other securities, or the shares of Common Stock are changed into a greater or lesser number of shares of Common Stock, the number and/or kind of shares and/or interests subject to an Option and the per share price or value thereof shall be appropriately adjusted by the Committee to give appropriate effect to such Reorganization. Any fractional shares or interests resulting from such adjustment shall be eliminated. Notwithstanding the foregoing, (i) each such adjustment with respect to an Incentive Option shall comply with the rules of Section 424(a) of the Code, and (ii) in no event shall any adjustment be made which would render any Incentive Option granted hereunder other than an "incentive stock option" for purposes of Section 422 of the Code. The maximum aggregate number of shares of Common Stock in respect of which Options may be granted under this Plan as provided for in Section 3 shall be subject to adjustment as contemplated above. In the event the Company is not the surviving entity of a Reorganization (not involving a Change of Control) and, following such Reorganization, any optionee will hold Options issued pursuant to this Plan which have not been exercised, canceled, or terminated in connection therewith, the Company shall cause such Options to be assumed (or canceled and replacement Options issued) by the surviving entity or a Related Entity. A Reorganization involving a Change of Control in which the Company is not the surviving entity shall be governed by Section 8. 10. ASSIGNMENT OR TRANSFER. (a) Except as otherwise expressly provided in any Non-Qualified Option, no Option granted under the Plan or any rights or interests therein shall be assignable or transferable by an optionee except by will or the laws of descent and distribution, and during the lifetime of an optionee, Options granted to him or E-6 264 her hereunder shall be exercisable only by the optionee or, in the event that a legal representative has been appointed in connection with the Disability of an optionee, such legal representative. (b) Notwithstanding any limitation on a Key Employee's or Eligible Non-Employee's right to transfer an Option, the Committee may (in its sole discretion) permit a Key Employee or Eligible Non-Employee to transfer an Option, or may cause the Company to grant an Option that otherwise would be granted to a Key Employee or Eligible Non-Employee, in any of the following circumstances: (a) pursuant to a qualified domestic relations order, (b) to a trust established for the benefit of the Key Employee or Eligible Non-Employee or one or more of the children, grandchildren, or spouse of the Key Employee or Eligible Non-Employee, as applicable; (c) to a limited partnership in which all the interests are held by the Key Employee or Eligible Non-Employee and that Person's children, grandchildren or spouse; or (d) to another Person in circumstances that the Committee believes will result in the Option continuing to provide an incentive for the Key Employee or Eligible Non-Employee to remain in the service of the Company or its Subsidiaries and apply his or her best efforts for the benefit of the Company or its Subsidiaries. If the Committee determines to allow such transfers or issuances of Option, any Key Employee or Eligible Non-Employee desiring such transfers or issuances shall make application therefor in the manner and time that the Committee specifies and shall comply with such other requirements as the Committee may require to assure compliance with all applicable laws, including securities laws, and to assure fulfillment of the purposes of this Plan. The Committee shall not authorize any such transfer or issuance if it may not be made in compliance with all applicable federal, state and foreign securities laws. The granting of permission for such an issuance or transfer shall not obligate the Company to register the shares of Common Stock to be issued under the applicable Option. 11. COMPLIANCE WITH SECURITIES LAWS. The Company shall not in any event be obligated hereunder to file any registration statement under the Securities Act or any applicable state securities law to permit exercise of any option or to issue any Common Stock in violation of the Securities Act or any applicable state securities law. Each optionee (or, in the event of his death or, in the event a legal representative has been appointed in connection with his Disability, the Person exercising the Option) shall, as a condition to his right to exercise any Option, deliver to the Company an agreement or certificate containing such representations, warranties and covenants as the Company may deem necessary or appropriate to ensure that the issuance of shares of Common Stock pursuant to such exercise is not required hereunder to be registered under the Securities Act or any applicable state securities law. Certificates for shares of Common Stock, when issued, may have substantially the following legend, or statements of other applicable restrictions, endorsed thereon, and may not be immediately transferable: THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS. THE SHARES MAY NOT BE OFFERED FOR SALE, SOLD, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF UNTIL THE HOLDER HEREOF PROVIDES EVIDENCE SATISFACTORY TO THE ISSUER (WHICH, IN THE DISCRETION OF THE ISSUER, MAY INCLUDE AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER) THAT SUCH OFFER, SALE, PLEDGE, TRANSFER OR OTHER DISPOSITION WILL NOT VIOLATE APPLICABLE FEDERAL OR STATE LAWS. This legend shall not be required for shares of Common Stock issued pursuant to an effective registration statement under the Securities Act and in accordance with applicable state securities laws. 12. WITHHOLDING TAXES. By acceptance of the Option, the optionee will be deemed to (i) agree to reimburse the Company or Related Entity by which the optionee is employed for any federal, state, or local taxes required by any government to be withheld or otherwise deducted by such corporation in respect of the optionee's exercise of all or a portion of the Option; (ii) authorize the Company or any Related Entity by which the optionee E-7 265 is employed to withhold from any cash compensation paid to the optionee or in the optionee's behalf, an amount sufficient to discharge any federal, state, and local taxes imposed on the Company, or the Related Entity by which the optionee is employed, and which otherwise has not been reimbursed by the optionee, in respect of the optionee's exercise of all or a portion of the Option; and (iii) agree that the Company may, in its discretion, hold the stock certificate to which the optionee is entitled upon exercise of the Option as security for the payment of the aforementioned withholding tax liability, until cash sufficient to pay that liability has been accumulated, and may, in its discretion, effect such withholding by retaining shares issuable upon the exercise of the Option having a Fair Market Value on the date of exercise which is equal to the amount to be withheld. 13. COSTS AND EXPENSES. The costs and expenses of administering the Plan shall be borne by the Company and shall not be charged against any Option nor to any employee receiving an Option. 14. FUNDING OF PLAN. The Plan shall be unfunded. The Company shall not be required to make any segregation of assets to assure the payment of any Option under the Plan. 15. OTHER INCENTIVE PLANS. The adoption of the Plan does not preclude the adoption by appropriate means of any other incentive plan for employees. 16. EFFECT ON EMPLOYMENT. Nothing contained in the Plan or any agreement related hereto or referred to herein shall affect, or be construed as affecting, the terms of employment of any Key Employee except to the extent specifically provided herein or therein.
