ITEM 1. BUSINESS. Special Note: Certain statements set forth below under this caption constitute "forward-looking statements" within the meaning of the Reform Act. See "Special Note Regarding Forward-Looking Statements" for additional factors relating to such statements. GENERAL Costilla Energy, Inc. ("Costilla" or the "Company") is an independent energy company that is engaged in the exploration, exploitation, development, and acquisition of oil and gas properties. The Company's primary operations are in the Permian Basin area of Texas and New Mexico, the Gulf Coast (onshore) and the Rocky Mountain regions. In 1996 the Company acquired an interest in an entity which has a concession for the development of mineral interests in the Republic of Moldova, in Eastern Europe. The Company's predecessor began operating in 1988 with the strategy of acquiring and exploiting undervalued oil and gas properties, and at December 31, 1992 had net proved reserves of 4.7 MMBOE. Since January 1, 1993, the Company has successfully closed seven transactions for an aggregate purchase price of approximately $101 million. As of January 1, 1997, the Company had total estimated net proved reserves of 17.0 Mmbbls of oil and 120.3 Bcf of gas, aggregating 37.0 MMBOE, with a PV-10 Value of approximately $311.8 million, all of which has been calculated pursuant to the requirements of the Securities and Exchange Commission. The Company also has a substantial undeveloped acreage position consisting of 242,541 gross (147,742 net) acres at December 31, 1996. The Company has identified in excess of 200 drilling locations of which 88 are included in its proved reserves. Costilla has in-house exploration expertise which uses 3-D seismic technology as a primary tool to identify drilling opportunities and has experienced high rates of success in each of its first two major 3-D seismic drilling programs. Since 1994, the Company has drilled 41wells based on these 3-D surveys, 36 of which have been productive. The Company has completed two additional 3-D surveys in 1996 on one of these acreage blocks. The Company currently plans to drill approximately 48 wells in 1997 based on its 3-D surveys. Since 1993, Costilla has generated significant growth in reserves and production. The Company increased its estimated proved reserves from 6.0 MMBOE at January 1, 1994 to 37.0 MMBOE at January 1, 1997 representing a compound annual growth rate of 83%. This reserve growth has been achieved at an average All-In Finding Cost of $3.68 per BOE over such period, a level which the Company believes is lower than industry averages. Concurrently, the Company increased its average net daily production from 827 BOE for the year ended December 31, 1993 to 8,907 BOE for the year ended December 31, 1996, representing a compound annual growth rate of 121%. The Company's production rate at December 31, 1996 was approximately 12,400 BOEPD. Oil and gas terms used herein are defined under "-Definition of Certain Oil and Gas Terms". 3 CORPORATE REORGANIZATION Costilla was incorporated in Delaware in June 1996 primarily to consolidate and continue the activities previously conducted by Costilla Energy, L.L.C., a Texas limited liability company (the "LLC"). Costilla was formed for the purpose of conducting a $60 million initial public offering of common stock and a $100 million senior notes offering (the "Offerings"), which Offerings were completed in early October 1996. The following is a description of sources and uses of proceeds from the Offerings (in millions): SOURCES: Notes Offering . . . . . . . . . . . . . . . . . . . . . . $ 100.0 Common Stock Offering. . . . . . . . . . . . . . . . . . . 65.9 (a) -------- $ 165.9 -------- -------- USES: Refinance Existing Debt. . . . . . . . . . . . . . . . . . $ 125.8 Redeem membership interests in the L.L.C. . . . . . . . . 15.5 Distributions to individual members to pay estimated income tax liability of such members in the L.L.C. . . . 3.4 Pro rata distribution to remaining member in the L.L.C.. . 0.8 Purchase of stock and assets of affiliated companies . . . 0.7 Working capital. . . . . . . . . . . . . . . . . . . . . . 10.7 Estimated fees, commissions, underwriting discounts and expenses related to the Offerings . . . . . . . . . . . . 9.0 -------- $ 165.9 -------- -------- - ------------------- (a) Includes 475,000 shares of the underwriter's over-allotment exercised subsequent to the closing of the common stock offering. The Company's executive offices are located at 400 West Illinois, Suite 1000, Midland, Texas, 79701 (mailing address P.O. Box 10369, Midland, Texas 79702) and its telephone number is (915) 683-3092. BUSINESS STRATEGY The Company's strategy is to increase its oil and gas reserves, production and cash flow from operations through a two-pronged approach which combines an active exploration program using 3-D seismic and other technological advances with the acquisition and exploitation of producing properties. The Company seeks to reduce its operating and commodity risks by holding a geographically diverse portfolio of properties, the reserves attributable to which are approximately balanced between oil and gas. The Company also seeks to manage the elements of its business strategy through the operation of a significant portion of its properties, the use of a rate of return analysis and the direct marketing and hedging of its oil and gas production. The elements of the Company's strategy may be further described as follows: - EXPLORATION EFFORTS. The Company uses extensive geological and geophysical analysis to carefully focus its 3-D seismic surveys. This focus allows the Company to successfully direct the size and scope of its exploration program in order to improve the likelihood of success while managing overall exploration costs. The Company's exploration efforts are concentrated currently in known producing regions. The Company's 1997 capital budget for exploration activities is $7.2 million, which includes the drilling of 26 exploratory wells. In addition, Costilla has $5.2 million budgeted for the acquisition of undeveloped acreage and seismic projects. 4 - EXPLOITATION ACTIVITIES. The Company is actively pursuing numerous exploitation opportunities within its existing properties, including areas where no proved reserves are currently assigned. Exploitation activities currently in progress include the drilling of development wells, recompletions, workovers, infill and horizontal drilling, a secondary recovery project and a carbon dioxide flood. The Company's 1997 capital budget for such activities is $13.6 million, which includes the drilling of 36 development wells. - PROPERTY ACQUISITIONS. The Company seeks to acquire producing properties where it has identified opportunities to increase production and reserves through both exploitation and exploration activities. The Company has increased the value of its acquisitions by aggressively managing the operations of existing proved properties and by successfully identifying and developing previously unproved reserves on acquired acreage. The Company seeks to acquire reserves which will fit its existing portfolio, are generally not being actively marketed and where a negotiated sale would be the method of purchase. The Company does not rely on major oil company divestitures or property auctions. - PROPERTY DIVERSIFICATION. The Company holds a portfolio of oil and gas properties located in the Permian Basin, the Gulf Coast and the Rocky Mountain regions. The Company believes that by conducting its activities in distinct regions it is able to reduce commodity price and other operational risks. The Company's Moldovan interest is an extension of this strategy and can be characterized by low initial costs, additional reserve potential and the availability of technical data that may be further developed by the Company. - CONTROL OF OPERATIONS. The Company prefers to operate and own the majority working interest in its properties. This allows the Company greater control over future development, drilling, completing and operating costs and marketing of production. At January 1, 1997, the Company operated wells constituting approximately 74% of its total PV-10 Value. SIGNIFICANT ACQUISITIONS 1995 ACQUISITION. In a $46.6 million acquisition completed in June 1995, the Company acquired a group of oil and gas properties located in the Permian Basin, Gulf Coast and Rocky Mountain regions. At the date of acquisition, the net proved reserves included 7.1 Mmbbls of oil and 44.1 Bcf of gas, aggregating 14.4 MMBOE. From the date of acquisition until December 31, 1996, the Company produced 2.8 MMBOE from the acquired properties and sold a portion of the acquired properties for approximately $3.6 million. At January 1, 1997, the net proved reserves of the remaining properties were 13.9 MMBOE. The acquired properties also included 103,010 gross (93,787 net) undeveloped acres. 1996 ACQUISITION. In June 1996, the Company acquired a group of oil and gas properties located primarily in the Permian Basin and Gulf Coast regions for an adjusted purchase price of approximately $38.7 million. This acquisition included properties with net proved reserves at April 1, 1996 of 5.0 Mmbbls of oil and 33.5 Bcf of gas, aggregating 10.6 MMBOE. The acquired properties also included 42,855 gross (16,646 net) undeveloped acres and a pipeline located in Pennsylvania, which was sold on December 31, 1996 for $3.3 million. RECENT DEVELOPMENTS On December 31, 1996, the Company closed the sale of all of the capital stock of a wholly owned subsidiary, which owned a 120 mile gas transportation pipeline in southwestern Pennsylvania, for net proceeds of $3.3 million. The pipeline was acquired through the 1996 Acquisition, was regarded as a non-strategic asset to the Company's business and had been held for resale. On December 31, 1996 the Company also closed the sale of substantially all of the assets of another wholly owned subsidiary, for net proceeds of approximately $3.0 million. The remaining assets of the subsidiary are held by the Company. 5 In 1996, the Company purchased a 40.5% membership interest in Republic Gas Partners, L.L.C., a Delaware limited liability company ("Republic"), for approximately $1,020,000. Republic owns and operates gas pipelines and associated facilities in Louisiana.In March 1997, the Company sold its investment in Republic for an amount equal to its original cost, plus interest from the date of purchase. COMPETITION AND MARKETS Competition in all areas of the Company's operations is intense. Major and independent oil and gas companies and oil and gas syndicates actively bid for desirable oil and gas properties, as well as for the equipment and labor required to operate and develop such properties. A number of the Company's competitors have financial resources and acquisition, exploration and development budgets that are substantially greater than those of the Company, which may adversely affect the Company's ability to compete with these companies. Many of the Company's competitors have been engaged in the energy business for a much longer time than the Company. 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 the Company's financial or human resources permit. The Company's ability to acquire additional properties and to discover reserves in the future will be dependent on its ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. The market for oil, gas and natural gas liquids produced by the Company depends on factors beyond its control, including domestic and foreign political conditions, the overall level of supply of and demand for oil, gas and natural gas liquids, the price of imports of oil and gas, weather conditions, the price and availability of alternative fuels, the proximity and capacity of gas pipelines and other transportation facilities and overall economic conditions. The oil and gas industry as a whole also competes with other industries in supplying the energy and fuel requirements of industrial, commercial and individual consumers. REGULATION The Company's oil and gas exploration, production and related operations are subject to extensive rules and regulations promulgated by federal, state and local agencies. Failure to comply with such rules and regulations can result in substantial penalties. The regulatory burden on the oil and gas industry increases the Company's cost of doing business and affects its profitability. Because such rules and regulations are frequently amended or reinterpreted, the Company is unable to predict the future cost or impact of complying with such laws. 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. Such 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 oil and gas wells and the regulation of spacing, plugging and abandonment of such wells. The statutes and regulations of certain states limit the rate at which oil and gas can be produced from the Company's properties. The Federal Energy Regulatory Commission ("FERC") regulates interstate natural gas transportation rates and service conditions. Such regulation affects the marketing of gas produced by the Company and the revenues received by the Company for sales of such production. Since the mid-1980s, FERC Orders have fundamentally restructured interstate pipeline sales and transportation services, including the unbundling by interstate pipelines of the sales, transportation, storage and other components of the city-gate sales services such pipelines previously performed. These regulatory measures may ultimately enhance the Company's ability to market and transport its gas, although it may also subject the Company to greater competition, more restrictive pipeline imbalance tolerances and greater penalties if those tolerances are violated. The FERC has recently announced several important transportation-related policy statements and proposed rule changes, including policy statements on how interstate natural gas pipelines can recover the cost of new pipeline facilities and policy statements on alternatives to its traditional cost-of-service ratemaking methodology (including criteria to be used in evaluating proposals to charge market-based rates for the transportation of natural gas). In addition, the FERC is reconsidering its regulations regarding releases of firm interstate natural gas pipeline capacity. While the Company cannot predict exactly how FERC actions might impact the Company's natural gas sales, it 6 does not believe it will be treated materially differently than other natural gas producers and marketers with which it completes. ENVIRONMENTAL MATTERS Operations of the Company are subject to numerous and constantly changing federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. These laws and regulations may require the acquisition of certain permits, restrict or prohibit the types, quantities and concentration of substances that can be released into the environment in connection with drilling and production, restrict or prohibit drilling activities that could impact wetlands, endangered or threatened species or other protected natural resources and impose substantial liabilities for pollution resulting form the Company's operations. Such laws and regulations may substantially increase the cost of exploring for, developing or producingoil and gas and may prevent or delay the commencement or continuation of a given project. In the opinion of the Company's management, the Company is in substantial compliance with current applicable environmental laws and regulations, and the cost of compliance with such laws and regulations has not been material and is not expected to be material during the next fiscal year. Nevertheless, changes in existing environmental laws and regulations or in interpretations thereof could have a significant impact on the operating costs of the Company, as well as the oil and gas industry in general. For instance, legislation has been proposed in congress from time to time that would reclassify certain oil and gas production wastes as "hazardous wastes," which reclassification would make exploration and production wastes subject to much more stringent handling, disposal and clean-up requirements. State initiatives to further regulate the disposal of oil and gas wastes and naturally occurring radioactive materials are also pending in certain states, including Texas, and these various initiatives could have a similar impact on the Company. The Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), also know as the "Superfund" law, imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons that are considered to have contributed to the release of a "hazardous substance" into the environment. These persons include the owner or operator of the disposal site or the site where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site. Persons who are or were responsible for releases of hazardous substances found at the site and persons who are or were responsible for releases of hazardous substances under CERCLA may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources, and it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. The Company is able to control directly the operation of only those wells with respect to which its acts as operator. Notwithstanding the Company's lack of control over wells operated by others, the failure of the operator to comply with applicable environmental regulations may, in certain circumstances, be attributed to the Company. The Company has no material commitments for capital expenditures to comply with existing environmental requirements. EMPLOYEES At December 31, 1996, the Company had 114 full time employees. None of the Company's employees is subject to a collective bargaining agreement. The Company considers its relations with its employees to be good. 7 DEFINITION OF CERTAIN OIL AND GAS TERMS The terms defined in this section are used throughout this Form 10-K.

At January 1, 1997, 53.5% of the Company's proved reserves were concentrated in the Permian Basin, an approximately 70-county region in West Texas and Southeast New Mexico. The Company's production comes from well known formations such as the Spraberry, Canyon, Ellenberger and Devonian. The majority of the Company's producing intervals in the Permian Basin range from 4,500 feet to 9,500 feet in depth. The Company has several exploratory projects in the Permian Basin based primarily on 3-D seismic surveys. The most significant include: EDWARDS/MCELROY RANCH PROSPECT, ECTOR AND CRANE COUNTIES, TEXAS. Costilla has identified 81 drilling locations on the Company's 14,623 gross (7,165 net) acres in this prospect based on an approximate 80-square mile 3-D seismic project. Through December 31, 1996, the Company drilled 15 wells on this prospect, of which 14 were successful resulting in three separate field discoveries. In addition, these wells have confirmed the Strawn and Wolfcamp trends which were identified by the seismic project undertaken jointly with Texaco Exploration and Production Inc. ("Texaco"). The Company plans to drill 20 wells in this trend in 1997, two of which were in progress at December 31, 1996. The Company's working interest in this prospect is approximately 49%. Costilla and Texaco are also evaluating the development of a Queen Sand field identified from the Edwards/McElroy Ranch seismic program. The six producing wells at December 31, 1996 were producing an aggregate of approximately 50 Bbls of oil per day. A pilot waterflood has been commenced and is being evaluated for additional development. The drilling of one additional Queen Sand well is anticipated in 1997. MACGYVER-GREEN ACRES PROSPECT, HOWARD COUNTY, TEXAS. The Company has identified 53 locations in this prospect based on information derived from approximately 30 square miles of 3-D seismic data that the Company acquired on the area in 1994. The Talbot Fuller well was the first well drilled by the Company on this prospect and was completed in the Canyon Lime formation at 8,600 feet in August 1994. From completion to December 31, 1996, the well produced 72 MBbls of oil and 287 Mmcf of gas, and averaged 54 Bbls of oil per day and 625 Mcf of gas per day during December 1996. Of the 24 wells which have been drilled on this prospect, 20 are productive. The 10 Company intends to drill 20 additional wells during 1997 on its 10,041 gross (7,229 net) acres. The Company's working interest in this prospect averages approximately 72%. The following two 3-D programs currently being undertaken by the Company in the Permian Basin are expected to provide additional drilling locations: WILSON RANCH 3-D PROJECT, PECOS COUNTY, TEXAS. The Wilson Ranch is located in northeastern Pecos County, approximately 10 miles west of the Yates field. In 1996 the Company completed an approximate 17-square mile seismic survey on the project. The project presents several potential exploration targets, including the Queen, San Andres, Wolfcamp, Devonian and Ellenberger formations, found at depths ranging from 1,600 to 8,000 feet. The Company has purchased a lease covering 3,750 gross acres on this 50,000 acre ranch. After acquiring the lease, the Company sold a portion of its interest in the lease to a major oil company, which left the Company with an approximately 53% working interest. The Company believes that there is significant potential in this area. DAVAN UNIT 3-D PROJECT, STONEWALL COUNTY, TEXAS. The Company has completed another 3-D seismic project to further develop the Company-operated Davan Unit. The project involves a 3-D seismic evaluation of approximately 4,380 gross acres adjacent to a Company-operated waterflood which has produced in excess of three Mmbbls of oil. The Company plans to drill four wells on this project during 1997. The Company's working interest in this project is 100%. An example of the Company's current exploitation efforts in the Permian Basin is: WORLD FIELD, CROCKETT COUNTY, TEXAS. This field was acquired in the 1996 Acquisition. It produces from the Grayburg formation at an average depth of 2550 feet. Discovered in 1926, it is one of the oldest and most prolific shallow fields in the Permian Basin. Costilla owns a 100% working interest in 4,380 acres containing 87 existing wells. At the time of acquisition, the field was producing approximately 480 Bbls of oil per day and 53,400 Bbls of water per day. In December, 1996 the Company initiated a polymer treatment program to reduce water production and increase oil cut. Thirteen treatments have been completed as of February 1997 resulting in oil production improving to approximately 650 Bbls of oil per day and water production dropping to approximately 43,500 Bbls of water per day. Additionally, some submersible pumps have been replaced by progressing cavity pumps which are expected to be significantly less costly to operate. A fieldwide study is underway to identify additional workover candidates as well as additional locations for development drilling. GULF COAST. At January 1, 1997, 22.6% of the Company's proved reserves were concentrated in the Gulf Coast region, on shore. The Company's production in this region primarily comes from known formations such as Frio, Yegua, Austin Chalk and Wilcox. The Company plans to use its expertise in aggressively developing 3-D opportunities on the extensive acreage position it holds in the region. Examples of such exploration projects in progress include: SEALY PROSPECT, AUSTIN COUNTY, TEXAS. The Sealy Field was acquired in the 1995 Acquisition and currently consists of 10,982 gross and net acres. The Wilcox formation in this field has produced over 66 Bcf of gas and there are subsurface indications of the presence of several fault blocks that lie untested. The Company's working interest in this prospect is 100%. The Company has acquired additional acreage in this prospect and plans to initiate a 3-D survey in 1997. SOUTHWEST SPEAKS, LAVACA COUNTY, TEXAS. This project was also acquired in the 1995 Acquisition and currently consists of 9,062 gross and net acres. Multiple producing horizons from shallow depths to below 14,000 feet have produced over 122 Bcf of gas from this highly faulted field. A well has been completed in the Rainbow Wilcox sand on acreage adjoining Costilla's lease. A well, in which Costilla holds a 10% interest as a result of a farmout, is 11 being completed on Costilla's lease. The Company has commenced a 3-D survey in the Speaks area in the first quarter of 1997. The Company's working interest in this prospect is 100%. BORCHERS FIELD, LAVACA COUNTY, TEXAS. This field was acquired by the Company in the 1996 Acquisition. The property is on trend with the Speaks project and is also a highly faulted field providing opportunity for further development. The Company's lease in the Borchers field area has produced over 21 Bcf of gas from two Wilcox sands. Costilla has a 100% working interest in this field consisting of 1,322 gross and net acres. Examples of exploitation activities in this region include: PERSONVILLE, LIMESTONE COUNTY, TEXAS. When this lease was acquired in the 1995 Acquisition, it was producing 70 Mcf per day from one well. In the last half of 1996, the Company completed two 11,000 foot Cotton Valley wells which were collectively producing approximately 4.5 Mmcf per day in December 1996. A third well was completed in January 1997. The Company plans 14 additional wells in this area. The Company is the operator and owns approximately 29% working interest in this 1,026 gross acre (298 net acre) lease. AUSTIN CHALK, BRAZOS, BURLESON, FAYETTE AND LEE COUNTIES, TEXAS. Costilla acquired the majority of the working interest in nine gross Austin Chalk wells in the 1995 Acquisition and an additional 80 gross Austin Chalk wells were included in the 1996 Acquisition. By mid-December 1996 the Company had worked over six wells via refracing and/or opening additional pay zones. Production has improved from 137 BOE per day to 325 BOE per day on those wells. Additional increases in production are expected as frac loads are recovered. Completion of the first two of seven planned horizontal wells in the Austin Chalk are the Patterson "G" 1-H, producing 326 barrels of oil and 727,000 cubic feet of gas per day, and Mais-Kachtik 1-H, producing 364 barrels of oil and 952,000 cubic feet of gas per day. Costilla has 30,414 gross (20,985 net) acres in the Austin Chalk area, and its working interest in this area averages approximately 69%. ROCKY MOUNTAIN. At January 1, 1997, 13.7% of the Company's proved reserves were concentrated in the Rocky Mountain region, which includes Montana, North Dakota, Wyoming, Colorado and Utah. The Company has a number of opportunities in the Rocky Mountain region involving 3-D seismic surveys, exploratory drilling and exploitation activities. Examples of each of these opportunities are: OUTLOOK FIELD, SHERIDAN COUNTY, MONTANA. The Company undertook its first Rocky Mountain 3-D seismic survey in the Outlook area to further develop the field. Three drilling locations were identified from the data of which the first well has been drilled and completed as a producer. Additional development is anticipated. Costilla has 5,169 gross (1,292 net) acres in the Outlook prospect, and its working interest is approximately 25%. WATTENBERG FIELD, WELD COUNTY, COLORADO. The Company operates 70 wells in the Wattenberg Field of the DJ Basin in northeast Colorado. During January, 1997 the Company initiated an 11 well development program of which 7 wells have been completed at March 20, 1997, with initial producing rates averaging 55 BOEPD per well. An estimated 20 additional locations are drillable. The Company owns an approximate 72% average working interest in 6,255 gross (4,479 net) acres. MARKETING ARRANGEMENTS The Company utilizes an active marketing program for a portion of its crude oil production in order to enhance the net price it receives. The Company sells its crude oil production from operated properties in North Dakota, Montana and Wyoming, at the lease level to an oil transportation company for the posted price, plus an agreed upon bonus, with a corresponding agreement to repurchase this production at its delivery point (typically, Cushing, Oklahoma) for a price equal to the then posted price for West Texas Intermediate crude oil less an agreed upon deduction for transportation and quality differentials, if any between the repurchased crude oil and West Texas 12 Intermediate crude oil. The Company then employs a broker to resell its crude oil to end users (such as refineries) on a month-to-month basis. The lease level sales and repurchase contracts are typically of six months durations. With respect to its other operated oil production (primarily located in Texas), the Company employs a similar price enhancement strategy, although the repurchase feature is absent. Instead, the lease level purchaser resells the crude oil to end users at the delivery point for the account of the Company. While these arrangements have the effect of increasing the net price the Company receives for its crude oil, such arrangements do not have the effect of limiting the Company's exposure to movements in crude oil prices. The Company markets its gas production at the lease level pursuant to month-to-month contracts. For the year ended December 31, 1996, one oil purchaser accounted for 11.2% of the Company's 1996 consolidated revenue. The Company does not anticipate any difficulty if it should have to replace any of the purchasers of its crude oil and natural gas. RISK MANAGEMENT The Company typically employs a strategy of purchasing put options on a portion of its anticipated oil and gas production. This strategy is designed to protect the Company from significant downward movements in commodity prices while preserving the benefit of rising prices. The Company does not establish hedges in excess of its anticipated production. The Company's current position with regard to its 1997 commodity hedges is as follows: OIL SALES. As of December 31, 1996, the Company had purchased put options on 6,536 barrels of oil per day for the calendar months June 1997 through October 1997 providing a floor price of $17.00 per barrel. Additionally, the Company had purchased put options on 2,500 Bbls of oil per day for 1997 which provide a floor price of $16.00 per barrel and sold call options on 2,500 barrels of oil per day for 1997 at $20.65 per barrel. These put options provide downside protection on approximately 70% of the Company's estimated 1997 oil production. GAS SALES. As of December 31, 1996, the Company had put options which provide a floor price of $1.65 per Mmbtu (approximately $1.82 per Mcf) for 150,000 Mmbtu's per month of its gas production through October 1997. In February 1997, the Company purchased put options which establish a floor price of $1.85 per Mmbtu (approximately $2.04 per Mcf) for 300,000 Mmbtu's per month of its gas production for the period April 1997 through October 1997. The put options currently in place represent approximately 25% of the Company's estimated gas production for 1997. 13 OIL AND GAS RESERVES The Company's estimated total proved and proved developed reserves of oil and gas as of January 1, 1997 were as follows: JANUARY 1, 1997 -------------------------- OIL GAS (MBBLS) (MMCF) MBOE ------- ------- ------ Proved developed producing . . . . 13,894 82,861 27,704 Proved developed non- producing. . . . . . . . . . . . 124 7,162 1,318 Proved undeveloped . . . . . . . . 2,982 30,249 8,023 ------ ------- ------ Total proved . . . . . . . . . . 17,000 120,272 37,045 ------ ------- ------ ------ ------- ------ The future net cash flows from the Company's estimated proved reserves as of January 1, 1997 were as follows: JANUARY 1, 1997 --------------- (in thousands) Future net cash flows before income taxes . . . . . . . . . . . . . . . . . . $538,343 Future net cash flows before income taxes, discounted at 10% . . . . . . . . . . . . . . . . . . . . . $311,803 The reserve estimates at January 1, 1997 were prepared by Williamson Petroleum Consultants, Inc. The reserve data set forth herein present estimates only. In general, estimates of economically recoverable oil and gas reserves and of the future net revenues therefrom are based upon an number of variable factors and assumptions, such as historical production from the subject properties, the assumed effects of regulation by governmental agencies and assumptions concerning future oil and gas prices and future operating costs, all of which may vary considerably from actual results. All such estimates are to some degree speculative, and classifications of reserves are only attempts to define the degree of speculation involved. For these reasons, estimates of the economically recoverable oil and gas reserves attributable to any particular group of properties, classifications of such reserves based on risk of recovery and estimates of the future net revenues expected therefrom, prepared by different engineers or by the same engineers at different times may vary substantially. The Company therefore emphasizes that the actual production, revenues, severance and excise taxes, development and operating expenditures with respect to its reserves will likely vary from such estimates, and such variances could be material. Estimates with respect to proved reserves that may be developed and produced in the future are often based upon volumetric calculations and upon analogy to similar types of reserves rather than actual production history. Estimates based on these methods are generally less reliable than those based on actual production history. Subsequent evaluation of the same reserves based upon production history will result in variations, which may be substantial, in the estimated reserves. In accordance with applicable requirements of the Securities and Exchange Commission (the "Commission"), the estimated discounted future net revenues from estimated proved reserves are based on prices and costs as of the date of the estimate unless such prices or costs are contractually determined at such date. Actual future prices and costs may be materially higher or lower. Actual future net revenues also will be affected by factors such as actual production, supply and demand for oil and natural gas, curtailments or increases in consumption by natural gas purchasers, changes in governmental regulations or taxation and the impact of inflation on costs. 14 PRODUCTION VOLUMES, PRICES AND COSTS The following table sets forth certain information regarding the Company's production volumes, average sales price and costs for the periods presented: YEAR ENDED DECEMBER 31, -------------------------- 1996 1995 1994 ------ ------ ------ Production: Oil (MBbls). . . . . . . . . . . . . 1,726 950 330 Gas (Mmcf) . . . . . . . . . . . . . 9,205 4,806 1,600 MBOE . . . . . . . . . . . . . . . . 3,260 1,751 597 Average Sales Price: Oil (per Bbl). . . . . . . . . . . . $19.87 $15.53 $15.25 Gas (per Mcf). . . . . . . . . . . . 2.13 1.45 1.63 Costs Per BOE: Production costs, including severance taxes (1). . . . . . . . $ 6.68 $ 5.91 $ 3.94 Depreciation, depletion and amortization . . . . . . . . . . . 3.81 3.40 3.09 - --------------------- (1) Production costs per BOE in 1996 and 1995 were unusually high as a result of relatively high workover expenses with respect to properties acquired in the 1995 Acquisition and the 1996 Acquisition which did not produce related production improvements until subsequent periods. Additionally, the Company's 1995 production costs were adversely affected by expenses incurred in connection with plugging wells to comply with applicable regulatory requirements. EXPLORATION AND DEVELOPMENT ACTIVITIES The Company drilled, or participated in the drilling of, the following number of wells during the periods indicated. At December 31, 1996, the Company was in the process of drilling 7 gross (4.33 net) wells and was in the process of completing 8 gross (4.04 net) wells as producers which are not reflected in the following table. 1996 1995 1994 ------------- ------------ ------------ GROSS NET GROSS NET GROSS NET ----- ----- ----- ----- ----- ---- Exploratory: Productive. . . . . 13 8.88 10 4.58 9 2.27 Dry . . . . . . . . 2 2.00 6 2.57 10 3.73 ----- ----- ----- ----- ----- ---- Total . . . . . . 15 10.88 16 7.15 19 6.00 ----- ----- ----- ----- ----- ---- ----- ----- ----- ----- ----- ---- Development: Productive. . . . . 16 9.93 1 0.44 - - Dry . . . . . . . . 5 3.20 - - - - ----- ----- ----- ----- ----- ---- Total . . . . . . 21 13.13 1 0.44 - - ----- ----- ----- ----- ----- ---- ----- ----- ----- ----- ----- ---- Total: Productive. . . . . 29 18.81 11 5.02 9 2.27 Dry . . . . . . . . 7 5.20 6 2.57 10 3.73 ----- ----- ----- ----- ----- ---- Total . . . . . . 36 24.01 17 7.59 19 6.00 ----- ----- ----- ----- ----- ---- ----- ----- ----- ----- ----- ---- 15 The Company does not own any drilling rigs and all of its drilling activities are conducted by independent contractors under standard drilling contracts.

In July 1995, the Republic of Moldova (located in Eastern Europe between Romania and the Ukraine) granted a Concession Agreement to Resource Development Company Limited, L.L.C. ("Redeco"), an entity not affiliated with the Company. The Company has paid Redeco $90,000 and agreed to bear the first $2.0 million of Concession expenses in return for a 50% interest in Redeco. After the initial $2.0 million expenditure, which was incurred in August 1996, the Company and the other member of Redeco are responsible for bearing 50.0% each of future expenses. To date, three wells, drilled by the government in the 1960s, have been reentered and two new wells have been completed by the Company in Moldova. The Company continues to evaluate the Concession for further development. TITLE TO PROPERTIES The Company has obtained title opinions on substantially all of its producing properties and believes that it has satisfactory title to such properties in accordance with standards generally accepted in the oil and gas industry. As is 16 customary in the oil and gas industry, the Company performs a minimal title investigation before acquiring undeveloped properties. A title opinion is obtained prior to the commencement of drilling operations on such properties. The Company's properties are subject to customary royalty interests, liens incident to operating agreements, liens for current taxes and other burdens which the Company believes do not materially interfere with the use of or affect the value of such properties. OPERATIONAL HAZARDS AND INSURANCE The Company's operations are subject to the hazards and risks inherent in drilling and production and transportation of oil and gas, including fires, natural disasters, explosions, encountering formations with abnormal pressures, blowouts, cratering, pipeline ruptures, and spills, any of which can result in loss of hydrocarbons, environmental pollution, personal injury or loss of life, severe damage to and destruction of properties of the Company and others, and suspension of operations. The Company maintains insurance of various types to cover its operations, including liability coverage and operator's extra expense coverage which provides for care, custody and control of all material wells drilled by the Company as operator. The Company believes that its insurance is adequate and customary for companies of a similar size engaged in operations similar to those of the Company, but losses could occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage. The Company's general policy is to only engage drilling contractors who provide substantial insurance coverage and name the Company as an additional named insured. The occurrence of a significant adverse event, the risks of which are not fully covered by insurance, could have a material adverse effect on the Company's financial condition and results of operations. Moreover, no assurances can be given that the Company will be able to maintain adequate insurance in the future at rates it considers reasonable. 17 ITEM 3. LEGAL PROCEEDINGS.

The ratio of Adjusted EBITDA to interest expense is calculated by dividing Adjusted EBITDA by interest. Adjusted EBITDA and the ratio of Adjusted EBITDA to interest expense should not be considered as alternatives to earnings (loss), or operating earnings (loss), as defined by generally accepted accounting principles, as indicators of the Company's financial performance or to cash flow as a measure of liquidity. 20 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Special Note: Certain statements set forth below under this caption constitute "forward-looking statements" within the meaning of the Reform Act. See "Special Note Regarding Forward-Looking Statements" for additional factors relating to such statements. GENERAL Costilla is an independent energy company engaged in the exploration, acquisition and development of oil and gas properties. The Company's predecessor began operating in 1988 and through mid-1995 had grown primarily through a series of small acquisitions of oil and gas properties and the exploitation of those properties. In June 1995, Costilla consummated the 1995 Acquisition for a purchase price of approximately $46.6 million, and in June 1996, the 1996 Acquisition was consummated for a purchase price of approximately $38.7 million. To date, the Company has achieved its high rate of growth primarily through acquisitions. This has impacted its reported financial results in a number of ways. Properties sold by others frequently have not received focused attention prior to sale. After acquisition, certain of these properties are in need of maintenance, workovers, recompletions and other remedial activity not constituting capital expenditures, which substantially increase lease operating expenses. The increased production and revenue resulting from these expenditures is predominately realized in periods subsequent to the period of expense. In addition, the rapid growth of the Company has required it to develop operating, accounting and administrative personnel compatible with its increased size. The Company believes it has now achieved a sufficient size to expand its reserve base without a corresponding increase in its general and administrative expense. The Company also believes it now has a sufficient inventory of prospects and the professional staff necessary to follow a more balanced program of exploration and exploitation activities to complement its acquisition efforts. Costilla's strategy is to increase its oil and gas reserves, production and cash flow from operations through a two-pronged approach which combines an active exploration program with the acquisition and exploitation of proved reserves. In addition, Costilla continues to evaluate the acquisition of undeveloped acreage for its exploration efforts. Costilla has in-house exploration expertise using 3-D seismic technology to identify new drilling opportunities as well as for the exploitation of acquired properties. Costilla has shown a significant increase in its oil and gas reserves and production, especially due to the 1995 Acquisition and the 1996 Acquisition. The following table sets forth certain operating data of Costilla for the periods presented: YEAR ENDED DECEMBER 31, ------------------------ 1996 1995 1994 ---- ---- ---- OIL AND GAS PRODUCTION: Oil (MBbls)................................. 1,726 950 330 Gas (Mmcf).................................. 9,205 4,806 1,600 MBOE........................................ 3,260 1,751 597 AVERAGE SALES PRICES (1): Oil (per Bbl)............................... $19.87 $15.53 $15.25 Gas (per Mcf)............................... 2.13 1.45 1.63 PRODUCTION COST (2): Per BOE (3)................................. $ 6.68 $ 5.91 $ 3.94 Per dollar of sales......................... 0.40 0.48 0.31 DEPRECIATION, DEPLETION AND AMORTIZATION: Per BOE...................................... $ 3.81 $ 3.40 $ 3.09 Per dollar of sales.......................... 0.23 0.27 0.24 21 _____________ (1) Before deduction of production taxes and net of any hedging results. (2) Production cost includes lease operating expenses and production and ad valorem taxes, if applicable, and excludes depreciation, depletion and amortization. (3) Production costs per BOE in 1995 and 1996 were unusually high as a result of relatively high workover expenses with respect to properties acquired in the 1995 Acquisition and the 1996 Acquisition which did not produce related production improvement until subsequent periods. Additionally, the Company's 1995 production costs were adversely affected by expenses incurred in connection with plugging wells to comply with applicable regulatory requirements. Costilla uses the successful efforts method of accounting for its oil and gas activities. Costs to acquire mineral interests in oil and gas properties, to drill and equip exploratory wells that result in proved reserves, and to drill and equip development wells are capitalized. Costs to drill exploratory wells that do not result in proved reserves, geological, geophysical and seismic costs, and costs of carrying and retaining unproved properties are expensed. Capitalized costs of producing oil and gas properties, after considering estimated dismantlement and abandonment costs and estimated salvage values, are depreciated and depleted using the unit-of-production method. Unproved oil and gas properties that are individually significant are periodically reviewed for impairment of value, and a loss is recognized at the time of impairment by providing an impairment allowance. Other unproved properties are amortized based on the Company's experience of successful drilling and average holding period. The Company utilizes option contracts to hedge the effect of price changes on a portion of its future oil and gas production. Premiums paid and amounts receivable under the option contracts are amortized and accrued to oil and gas sales, respectively. If market prices of oil and gas exceed the strike price of put options, the options will expire unexercised, therefore, reducing the effective price received for oil and gas sales by the cost of the related option. Conversely, if market prices of oil and gas decline below the strike price of put options, the options will be exercised, therefore, increasing the effective price received for oil and gas sales by the proceeds received from the related option. The net effect of the Company's commodity hedging activities reduced oil and gas revenues by $1,705,000, $80,000 and $9,000 for the years ended December 31, 1996, 1995, and 1994, respectively. The Company utilizes interest rate swap agreements to reduce the potential impact of increases in interest rates on floating-rate, long term debt. If market rates of interest experienced during the applicable swap term are below the rate of interest effectively fixed by the swap agreement, the rate of interest incurred by the Company will exceed the rate that would have been experienced under the Credit Agreement. The net effect of the Company's interest rate hedging activities increased interest expense in 1996 by $442,000 prior to repayment of the Company's floating rate debt and $8,000 for the year ended December 31, 1995. Concurrent with the payment of all of the Company's floating rate debt from proceeds of the Offerings in the fourth quarter of 1996, the interest rate swap agreements ceased to qualify as hedges. These interest rate swap agreements were marked-to-market and the related liability recorded. The liability for the two interest rate swap agreements was $1,712,000 at December 31, 1996. The Company must mark the agreements to market at the end of each reporting period and the net change during the reporting period will be treated as investment gain or loss. At March 11, 1997 the value of the agreements was an approximate $1.5 million liability. The Company's predecessor was classified as a partnership for federal income tax purposes. Therefore, no income taxes were paid or provided for by the Company prior to the Offerings. Future tax amounts, if any, will be dependent upon several factors, including but not limited to the Company's results of operations. RESULTS OF OPERATIONS YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 The Company's total oil and gas revenues for the year ended December 31, 1996 were $53,919,000, representing an increase of $32,226,000 (149%) over revenues of $21,693,000 in 1995. This increase was primarily due to the 1996 Acquisition and 1995 Acquisition, which accounted for approximately $12,754,000 and $14,059,000 of the revenue increase, respectively. The remainder of the increase was due to a combination of increased product prices, successful drilling activities and the enhancement of existing production. The average oil price per barrel received in 1996 was $19.87 compared to $15.53 in 1995, a 28% increase, and the average gas price received in 1996 was $2.13 compared to $1.45 in 1995, a 47% increase. 22 Oil and gas production was 3,260 MBOE in 1996 compared to 1,751 MBOE in 1995, an increase of 86%. Of the 1,509 MBOE increase, approximately 723 MBOE was due to the properties acquired in the 1996 Acquisition and 562 MBOE was due to the properties acquired in the 1995 Acquisition. The remainder of the increase was due to a combination of successful drilling activities and the enhancement of existing production. Interest and other revenues were $40,000 for the year ended December 31, 1996 compared to $123,000 in 1995, representing a decrease of $83,000, which was primarily comprised of $195,000 in losses on investments held for trading purposes and an increase in interest income of $67,000 in 1996 due to increased funds earning interest. Also in 1996, the Company realized gains of $ 1,067,000 on various transactions for which no comparable sales were recorded in 1995. Oil and gas production costs in 1996 were $21,774,000 ($6.68 per BOE), compared to $10,355,000 in 1995 ($5.91 per BOE), representing an increase of $11,419,000 (110%), due principally to the 1996 Acquisition and to a lesser extent the 1995 Acquisition. On a per BOE basis, production costs increased $0.77 due primarily to higher production costs per BOE for the properties acquired in the 1996 Acquisition. General and administrative expenses for the year ended December 31, 1996 were $5,238,000, representing an increase of $1,667,000 (47%) from 1995 of $3,571,000. The increase is primarily due to an increase in personnel and related costs necessary to accommodate the increased activities of the Company due to the 1995 and 1996 Acquisitions. However, as noted above, production volumes increased 86% and, therefore, general and administrative expenses per BOE decreased to $1.61 per BOE for the year ended December 31, 1996 from the $2.04 per BOE in 1995. Results of operations for the year ended December 31, 1995 include non-cash compensation expense of $656,000 deemed to have been accrued to a minority interest owner of the Company who was deemed to have benefited from the cancellation of an option to purchase an additional interest held by the other minority interest owner. Exploration and abandonment expense increased to $2,550,000 in 1996 compared to $1,650,000 in 1995. The Company incurred $913,000 of seismic costs for the year ended December 31, 1996, compared to $790,000 which were incurred in 1995. Dry hole and abandonment costs increased to $1,524,000 in 1996 from $860,000 in 1995. Depreciation, depletion and amortization expense for 1996 was $12,430,000 compared to $5,958,000 for 1995, representing an increase of $6,472,000 (109%). During 1996, depreciation, depletion and amortization on oil and gas production was provided at an average rate of $3.81 per BOE compared to $3.40 per BOE for 1995. The increases were due primarily to the 1996 and 1995 Acquisitions. Interest expense was $11,281,000 in 1996, compared to $4,591,000 in 1995. The $6,690,000 (146%) increase was attributable primarily to increased levels of debt which the Company used to finance the 1996 Acquisition. The average amounts of applicable interest-bearing debt in 1996 and 1995 were $95,671,000 and $49,972,000, respectively. The effective annualized interest rate in 1996 was 11.8%, as compared to 9.2% in 1995. Results of operations for the year ended December 31, 1996 include an extraordinary charge of $4,975,000, net of the related deferred tax benefit of $1,042,000, related to the early extinguishment of the Company's prior bank credit facilities ( the "1995 Credit Facility and the Bridge Facility"). The 1995 Credit Facility was replaced by the Bridge Facility in June 1996 and the Bridge Facility was paid off with proceeds from the Offerings in October 1996. YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994 The Company's total oil and gas revenues for 1995 were $21,693,000, representing an increase of $14,056,000 (184%) over revenues of $7,637,000 in 1994. This increase was primarily due to the 1995 Acquisition which accounted for approximately $13,373,000 of the revenue increase. Oil and gas production was 1,751 MBOE in 1995 and 597 MBOE in 1994. Of the 1,154 MBOE increase, 1,099 MBOE was due to the properties acquired in the 1995 Acquisition. 23 Interest and other revenues were $123,000 in 1995 compared to $87,000 in 1994, representing an increase of $36,000 (41%), which was comprised of an increase in interest income of $59,000 in 1995 due to an increased amount of funds earning interest, partially offset by a decrease of other income of $23,000. In 1994, the Company realized a gain of $112,000 on the sale of various properties for which there were no comparable gains in 1995. Oil and gas production costs in 1995 were $10,355,000 ($5.91 per BOE), compared to $2,351,000 in 1994 ($3.94 per BOE), representing an increase of $8,004,000 (340%). The major portion of the increase was due to increased production associated with the 1995 Acquisition. In addition, certain acquired properties required remedial workovers and other activity immediately following acquisition resulting in unusual operating costs of approximately $600,000 during 1995. In addition, $1,605,000 of operating costs were incurred in connection with properties acquired in late 1994. General and administrative expense for 1995 was $3,571,000, representing an increase of $2,387,000 (202%) from 1994 expense of $1,184,000. The increase is primarily due to an increase in personnel and related costs necessary to accommodate the increased activities of the Company due to the 1995 Acquisition. Results of operations for the year ended December 31, 1995 include non-cash compensation expense of $656,000 deemed to have been accrued to a minority interest owner of the Company in connection with the cancellation of an option to purchase an additional interest in the Company held by the other minority interest owner. Exploration and abandonment expense increased to $1,650,000 in 1995 compared to $793,000 in 1994. The increase of $857,000 (108%) was comprised principally of $790,000 of seismic costs. Depreciation, depletion and amortization expense for 1995 was $5,958,000 compared to $1,847,000 for 1994, representing an increase of $4,111,000 (223%). During 1995 depreciation, depletion and amortization on oil and gas production was provided at an average rate of $3.40 per BOE compared to $3.09 per BOE for 1994. The increase was due primarily to the 1995 Acquisition. Interest expense was $4,591,000 in 1995 compared to $1,458,000 in 1994. The $3,133,000 (215%) increase was attributable to increased levels of debt which the Company used to finance the 1995 Acquisition. The average amounts of applicable interest-bearing debt in 1995 and 1994 were $49,972,000 and $17,632,000, respectively. LIQUIDITY AND CAPITAL RESOURCES NET CASH USED IN OPERATING ACTIVITIES For the year ended December 31, 1996, net cash provided by operating activities increased to $12.4 million from $6.4 million for 1995. Cash provided by operations, before changes in operating assets and liabilities, increased to $14.7 million from $1.7 million for 1995 due primarily to the 1996 Acquisition and the increase in results of operations therefrom. NET CASH USED IN INVESTING ACTIVITIES Net cash used in investing activities for the year ended December 31, 1996 was $64.1 million. Approximately $38.7 million was used for the 1996 Acquisition, $28.7 million was used for other oil and gas expenditures and $3.0 million was used for other property and equipment. During the year ended December 31, 1996, approximately $6.3 million net cash was provided by sales of oil and gas properties. For the year ended December 31, 1995, net cash used in investing activities was $62.5 million. Approximately $46.6 million was used for the 1995 Acquisition, $14.9 million for additional acquisition of producing oil and gas properties and exploration and development activities and $1.0 million primarily for other property and equipment. NET CASH PROVIDED BY FINANCING ACTIVITIES The Company entered into a $125.0 million senior credit agreement in June 1996, which was fully funded prior to the Company's initial public offering of Common Stock in October 1996. Approximately $74.5 million was for the 24 extension and refinancing of prior debt, $42.5 million was used for the 1996 Acquisition and approximately $8.0 million was used for general corporate purposes. CAPITAL RESOURCES Funding for the Company's business activities has historically been provided by bank financings, cash flow from operations, private equity sales, property divestitures and joint ventures with industry participants. The Company completed a $10 million private equity placement in February 1995. Subsequently, the 1995 Acquisition and the 1996 Acquisition were substantially funded by bank financings. The Company plans to finance its continuing operations and execute its business strategy with cash flow from operations and borrowings under the Credit Facility. While the Company regularly engages in discussions relating to potential acquisitions, the Company has no present agreement, commitment or understanding with respect to any such acquisition, other than the acquisition of undeveloped acreage and various mineral interests in its normal course of business. Any future acquisition may require additional financing and will be dependent upon financing arrangements available at the time. The Company believes that cash flow from operations will be sufficient for its budgeted 1997 capital expenditures. However, because the Company's ultimate 1997 capital expenditures, future cash flows and the availability of financing are subject to a number of variables, there can be no assurance that the Company's capital resources will be sufficient to maintain its capital expenditures. In addition, if the Company is unable to generate sufficient cash flow from operations to service its debt, it may be required to refinance all or a portion of its debt, including the Notes, or to obtain additional financing. There can be no assurance that any such refinancing would be possible or that any additional financing could be obtained. The Company has the Credit Facility with NationsBank of Texas, N.A. (the "Bank"). The Credit Facility provides for a revolving line of credit with the availability of funds and letters of credit being subject to a borrowing base determination at least semi-annually. The borrowing base provides for a maximum availability of $50.0 million (which amount was also the initial borrowing base), $100,000 of which was borrowed at December 31, 1996. Availability under the borrowing base is initially limited to $20.0 million for working capital and $30.0 million for acquisitions of oil and gas properties meeting certain criteria established by the Bank. Borrowings under the Credit Facility bear interest at the Company's option at a floating rate which is at or above the NationsBank, N.A. prime rate or the LIBOR rate, depending on the percentage of committed funds which have been borrowed. Interest is payable quarterly and principal is amortized in twelve equal installments commencing, October 1998. Under the Credit Facility, the Company is obligated to pay certain fees to the Bank, including a commitment fee based on the unused portion of the commitment. The Credit Facility contains customary restrictive covenants (including restrictions on the payment of dividends and the incurrence of additional indebtedness) and requires the Company to maintain a current ratio of not less than 1.0 to 1.0, a ratio of Adjusted EBITDA to interest expense of not less than 2.0 to 1 and a minimum tangible net worth. At December 31, 1996, the Company's current ratio was 2.0 to 1.0, the ratio of Adjusted EBITDA to interest expense was 3.9 to 1 and the Company exceeded the tangible net worth test. Borrowings under the Credit Facility are secured by substantially all of the assets of the Company. Although certain of the Company's costs and expenses may be affected by inflation, inflationary costs have not had a significant effect on the Company's results of operations. CAPITAL EXPENDITURES The Company requires capital primarily for the exploration, development and acquisition of oil and gas properties, the repayment of indebtedness and general working capital needs. The Company's capital budget for 1997 is $26.0 million of which approximately $7.2 will be expended for exploratory drilling, approximately $13.6 million for exploitation activities, approximately $2.5 million for the purchase of undeveloped acreage and approximately $2.7 million for new seismic projects. 25 ITEM 8.

F-7 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1) ORGANIZATION AND NATURE OF OPERATIONS Costilla was incorporated in Delaware in June 1996 to consolidate and continue the activities previously conducted by Costilla Energy, L.L.C., a Texas limited liability company (the "LLC"), and its wholly owned subsidiaries, to acquire the assets of CSL Management Corporation ("CSL") (which owns certain office equipment used by the Company), and to acquire the stock of Valley Gathering Company ("Valley"). Costilla was formed for the purpose of conducting a $60 million initial public offering of common stock and a $100 million senior notes offering (the "Offerings"), which Offerings were completed in early October 1996. At December 31, 1994, the financial statements of the LLC and its affiliates were combined. The combining companies were owned by three individuals prior to the formation of the LLC. Such individuals owned exactly the same proportionate interest in each of the combining companies prior to their combination into the LLC on February 14, 1995. Each individual held exactly the same proportionate interest in the combining companies as was their proportionate interest in the LLC after its formation. Management believes, based on the exact same proportionate interests being held in the combining companies and the LLC before and after the date of its formation, that the combination lacks substance and is not the purchase of a minority interest. The LLC was formed on February 14, 1995 as the successor to CSL Partners, a Texas general partnership, which was organized on January 11, 1989. Subsequent to the formation of the LLC, NationsBank Capital Corporation ("NBCC") acquired a 30% interest in the LLC as described in Note 12. Contemporaneously with the closings of the Offerings: (1) the redeemable membership interests of NBCC in the LLC were redeemed for $15.5 million; (2) the LLC was merged into Costilla (the "Merger") and an aggregate of 5,200,000 shares of Common Stock were issued to the members of the LLC; (3) Costilla acquired all of the issued and outstanding stock of Valley and the assets of CSL for $0.7 million; and (4) $4.2 million in distributions were made to the members of the LLC, $3.4 million of which was provided to former members for certain income tax effects of the Merger. The LLC was an unincorporated association of several individuals and a corporation and ceased to exist on the date of the Offerings. The Company is an oil and gas exploration and production concern with properties located principally in West Texas, South Texas, and the Rocky Mountain regions of the United States. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION As of December 31, 1996, the consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The Company proportionately consolidates less than 100%-owned oil and gas partnerships and joint ventures in accordance with industry practice. All significant accounts and transactions between the Company and its subsidiaries have been eliminated. At December 31, 1996 Costilla had three wholly owned subsidiaries: (i) Costilla Petroleum Corporation, a Texas corporation ("CPC"), which operated properties owned by Costilla and owned minor interests in the same properties, (ii) Statewide Minerals, Inc., a Texas corporation ("Statewide"), which had engaged in the purchase of small royalty and mineral interests; and (iii) Valley, which owns several small gas gathering systems, a small gas processing plant, certain salt water disposal systems and gas compressors. Costilla and CPC were the sole members of two Texas limited liability companies through which the Company's Moldovan operations are conducted. F-8 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS USE OF ESTIMATES Preparation of the accompanying consolidated 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 For purposes of the statements of cash flows, cash and cash equivalents include cash on hand and depository accounts held by banks. CONCENTRATIONS OF CREDIT RISK Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of unsecured accounts receivable from unaffiliated working interest owners and crude oil and natural gas purchasers. During the year ended December 31, 1996, the Company had sales to one customer which accounted for 11.2% of total revenues. During the year ended December 31, 1995, the Company had sales to one customer which accounted for 17.7% of total revenues. TRADE RECEIVABLES Trade receivables generally consist of amounts due from outside working interest owners for their proportionate share of drilling and operating costs incurred by the Company, as operator of the related properties. HEDGING AND DERIVATIVE FINANCIAL INSTRUMENTS The financial instruments that the Company accounts for as hedging contracts must meet the following criteria: the underlying asset or liability must expose the Company to price or interest rate risk that is not offset in another asset or liability, the hedging contract must reduce that price or interest rate risk, and the instrument must be designated as a hedge at the inception of the contract and throughout the contract period. In order to qualify as a hedge, there must be clear correlation between changes in the fair value of the financial instrument and the fair value of the underlying asset or liability such that changes in the market value of the financial instrument will be offset by the effect of price or interest rate changes on the exposed items. Premiums paid for commodity option contracts and interest rate swap agreements which qualify as hedges are amortized to oil and gas sales and interest expense, respectively, over the terms of the agreements. Unamortized premiums are included in other assets in the consolidated balance sheet. Amounts receivable under the commodity option contracts and interest rate swap agreements are accrued as an increase in oil and gas sales and a reduction of interest expense, respectively, for the applicable periods. When these derivative financial instruments cease to qualify as hedges, these instruments are classified as investments held for trading purposes. Investments held for trading purposes are marked to market at the end of each reporting period and the net balance change is recorded as other income in the consolidated statement of operations for the applicable period. OIL AND GAS PROPERTIES The Company uses the successful efforts method of accounting for oil and gas producing activities. Costs to acquire mineral interests in oil and gas properties, to drill and equip exploratory wells that find proved reserves, and to drill and equip development wells are capitalized. Costs to drill exploratory wells that do not find proved reserves, geological and geophysical costs, and costs of carrying and retaining unproved properties are expensed. F-9 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Unproved oil and gas properties that are individually significant are periodically assessed for impairment of value, and a loss is recognized at the time of impairment by providing an impairment allowance. Other unproved properties are amortized based on the Company's experience of successful drilling and average holding period. Capitalized costs of producing oil and gas properties, after considering estimated dismantlement and abandonment costs and estimated salvage values, are depreciated and depleted by the unit-of-production method. Support equipment and other property and equipment are depreciated over their estimated useful lives of the assets, which range from 5 to 7 years. Prior to the adoption of FAS 121 on January 1, 1995, the Company's aggregate oil and gas properties were carried at cost, not in excess of total estimated undiscounted future net revenues, on a worldwide basis. On sale or retirement of a complete unit of a proved property, the cost and related accumulated depreciation, depletion, and amortization are eliminated from the property accounts, and the resultant gain or loss is recognized. On retirement or sale of a partial unit of proved property, the cost is charged to accumulated depreciation, depletion, and amortization with a resulting gain or loss recognized in income. On sale of an entire interest in an unproved property for cash or cash equivalent, gain or loss on the sale is recognized, taking into consideration the amount of any recorded impairment if the property had been assessed individually. If a partial interest in an unproved property is sold, the amount received is treated as a reduction of the cost of the interest retained. IMPAIRMENT OF LONG-LIVED ASSETS As of January 1, 1995, the Company adopted the provisions of Statement of Financial Accounting Standards No. 121 - ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF ("FAS 121"). Consequently, the Company reviews its long-lived assets to be held and used, including oil and gas properties accounted for under the successful efforts method of accounting, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future cash flows, on a depletable unit basis, is less than the carrying amount of such assets. In this circumstance, the Company recognizes an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset. DEFERRED CHARGES The Company capitalized certain costs incurred in connection with the issuance of $100 million of senior notes and with obtaining the 1996 Credit Facility (see Note 7 for definitions and descriptions of each). These costs are being amortized over the lives of the related instruments. DEFERRED REVENUE In November 1995, the Company entered into gas sales agreements whereby it committed to delivery of a total of 2,379,000 MMbtu, from December 1, 1995 through December 31, 1996, for a total fixed price of $3,429,610. Income from such agreements is generally recognized in the period of delivery. REVENUE RECOGNITION The Company uses the sales method of accounting for crude oil revenues. Under this method, revenues are recognized based on actual volumes of oil sold to purchasers. The Company uses the entitlements method of accounting for natural gas revenues. Under this method, revenues are recognized based on actual production of natural gas. Natural gas revenues would not have been significantly altered in any period had the sales method of recognizing natural gas revenues been utilized. F-10 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS STOCK-BASED COMPENSATION The Company accounts for employee stock-based compensation using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"). Accordingly, the Company has only adopted the disclosure provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"). See Note 12 for the pro forma disclosures of compensation expense determined under the fair-value provisions of SFAS 123. INCOME TAXES The Company accounts for income taxes in accordance with the provisions of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). Under the asset and liability method of SFAS 109, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under SFAS 109, the effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. EARNING PER SHARE Primary net income (loss) per share is computed based on the weighted average number of shares of common stock and common stock equivalents outstanding during the period. Common stock equivalent shares arising from stock options are computed using the treasury stock method. There were no potentially dilutive securities, other than common stock equivalents. Consequently, primary and fully diluted earnings per share do not differ. For the periods prior to the Offerings, the weighted average shares outstanding attributable to predecessor capital are the 5,200,000 shares issued to the predecessor members upon conversion of the LLC. ENVIRONMENTAL The Company is subject to extensive Federal, state and local environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and may require the Company to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a noncapital nature are recorded when environmental assessment and/or remediation is probable, and the costs can be reasonably estimated. RECLASSIFICATIONS Certain reclassifications have been made to the 1995 and 1994 financial statements to conform to the 1996 presentation. (3) ACQUISITION OF OIL AND GAS PROPERTIES On June 14, 1996, the Company consummated the purchase from Parker and Parsley Petroleum Company of certain oil and gas properties for an estimated adjusted purchase price of approximately $38.7 million (the "1996 Acquisition"). The properties are located primarily in south and west Texas. The transaction was accounted for using the purchase method. The results of operations of the acquired properties are included in the Consolidated Statements of Operations as of the acquisition closing date, June 14, 1996. The Company sold for approximately $3.3 million its wholly-owned subsidiary, Costilla Pipeline Corporation, which owned the Three Rivers Pipeline F-11 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS purchased in the 1996 Acquisition. Certain other acquired properties, which were located outside the Company's areas of strategic focus, were sold in 1996. No gain or loss was recorded on these sales. In June 1995 the Company acquired a group of oil and gas properties from Parker and Parsley Petroleum Company for approximately $46.6 million (the "1995 Acquisition"). The properties are located in the Permian Basin, Gulf Coast and Rocky Mountain regions. The transaction was accounted for using the purchase method. The results of operations of the acquired properties are included in the Consolidated Statements of Operations as of the acquisition date of June 12, 1995. Certain other acquired properties, which were located outside the Company's areas of strategic focus, were sold in 1995. No gain or loss was recorded on these sales. PRO FORMA RESULTS OF OPERATIONS (UNAUDITED) The following table reflects the pro forma results of operations as though the 1995 Acquisition and 1996 Acquisition, net of the related properties sold, had occurred on January 1, 1995. The pro forma amounts are not necessarily indicative of the results that may be reported in the future.

FAS 121 requires that long-lived assets held and used by an entity, including oil and gas properties accounted for under the successful efforts method of accounting, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets to be disposed of are to be accounted for at the lower of carrying amount or fair value less cost to sell when management has committed to a plan to dispose of the assets. All companies, including successful efforts oil and gas companies, are required to adopt FAS 121 for fiscal years beginning after December 15, 1995. In order to determine whether an impairment had occurred, the Company estimated the expected future cash flows of its oil and gas properties on a depletable unit basis and compared such future cash flows to the carrying amount of the related oil and gas properties to determine if the carrying amount was recoverable. Based on this process, no writedown in the carrying amount of the Company's proved properties was necessary at December 31, 1996 or 1995. (5) DERIVATIVE FINANCIAL INSTRUMENTS The Company utilizes derivative financial instruments to manage well-defined interest rate and commodity price risks. The Company is exposed to credit losses in the event of nonperformance by the counterparties to its interest rate swap agreements and its commodity hedges. The Company anticipates, however, that such counterparties will be able to fully satisfy their obligations under the contracts. The Company does not obtain collateral or other security to support financial instruments subject to credit risk but monitors the credit standing of the counterparties. F-12 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS COMMODITY HEDGES. The Company utilizes option contracts to hedge the effect of price changes on future oil and gas production. If market prices of oil and gas exceed the strike price of put options, the options will expire unexercised, therefore reducing the effective price received for oil and gas sales by the cost of the related option. The following table sets forth the future volumes hedged by year and the weighted-average strike price of the option contracts at December 31, 1996: OIL GAS VOLUME VOLUME STRIKE PRICE (BBLS) (MMBTU) PER BBL/MMBTU --------- --------- ------------------ Oil: 1997 . . . . . . . . . . . . . . . . .1,912,500 - $16.52 - $20.65(a) Gas: 1997 . . . . . . . . . . . . . . . . . - 1,500,000 $1.65(b) - ----------------------- (a) Represents the weighted-average price of a purchased put option contract and of a collar established with the purchase of a put option contract and the sale of a call option contract. (b) Represents the strike price on a purchased put option contract. INTEREST RATE SWAP AGREEMENTS. Prior to the Offerings, the Company utilized two interest rate swap agreements to reduce the potential impact of increases in interest rates on floating-rate long-term debt. Concurrent with the issuance of the $100 million of 10.25% fixed-rate senior notes in early October 1996, the two interest rate swap agreements ceased to be hedges. These interest rate swap agreements were marked-to-market and the related liability recorded. The liability for the two interest rate swap agreements was $1,712,000 at December 31, 1996. The average balance of this liability during the quarter ended December 31, 1996 was approximately $1,700,000. During the quarter ended December 31, 1996, the Company recorded investment losses of $207,300 on the interest rate swap agreements. The following table sets forth the terms, fixed rates, and notional amounts of the interest rate swap agreements in place as of December 31, 1996: NOTIONAL PRINCIPAL FIXED TERM AMOUNT INTEREST RATE - -------------------------------- ----------- ------------- Jan. 25, 1996 to Jan. 25, 1999 $24 million 7.50% May 24, 1995 to May 27, 1997 (a) $60 million 5.99% - ----------------------- (a) Subject to extension until May 24, 1999 at the option of the counterparty. (6) FAIR VALUE OF FINANCIAL INSTRUMENTS The following table presents the carrying amounts and estimated fair values of the Company's financial instruments at December 31, 1996 and 1995. FASB Statement No. 107, DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS, defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments: CASH, TRADE RECEIVABLES, NOTES RECEIVABLE-OTHER AND TRADE PAYABLES: The carrying amounts approximate fair value because of the short maturity of those instruments. COMMODITY OPTION CONTRACTS: The carrying amount comprises the unamortized premiums paid for the option contracts. The fair value is estimated using option pricing models and essentially values the potential for the option contracts to become in-the-money through changes in commodity prices during the remaining terms. NOTES RECEIVABLE-AFFILIATE: The amounts reported relate to notes receivable from an affiliated company. The carrying amount reflects an estimate of net present value using an assumed annual interest rate of 9% based upon the anticipated note payment schedule. DEFERRED REVENUE: The amounts reported relate to the gas purchase agreements described in Note 2. The carrying amount represents the payments received under the agreements for which subsequent delivery is required. The fair value is estimated based upon the commodity price at December 31, 1995 for a similar agreement. LONG-TERM DEBT: The fair value of the Corporation's long-term debt is based upon the quoted market price for this issue at December 31, 1996. INTEREST RATE SWAP AGREEMENTS: At December 31, 1996, the Company had two interest rate swap agreements outstanding with an aggregate notional amount of $84 million. These agreements are more fully described in Note 5. The carrying amount is equal to the sum of the unamortized premiums paid for the agreements and the fair value. The fair values of each of the open interest rate swap agreements were obtained from bank quotes and represent the estimated amount the Company would pay upon termination of the agreements at December 31, 1996, taking into consideration interest rates at that date.

The notes were sold at par and interest is payable April 1 and October 1, commencing April 1, 1997. The Notes may not be redeemed prior to October 1, 2001, and thereafter at a premium reducing to par, plus interest, by maturity. There is no mandatory redemption of the Notes required prior to maturity. The notes are general unsecured senior obligations of the Company and rank equally in right of payment with all other senior indebtedness of the Company and senior in right of payment of all existing future subordinated indebtedness of the Company. The Notes are subject to an Indenture between the Company and a trustee. The Indenture restricts, among other things, the Company's ability to incur additional indebtedness, pay dividends or make certain other restricted payments, incur liens, engage in any sale and leaseback transaction, sell stock of subsidiaries, apply net proceeds from certain assets sales, merge or consolidate with any other person, sell, assign, transfer, lease, convey or otherwise dispose of substantially all of the assets of the company, or enter into certain transactions with affiliates. Net proceeds from the sale of the Notes of approximately $96.1 million were used to repay existing indebtedness. In October 1996, the Company entered into a credit agreement (the "1996 Credit Facility") with NationsBank of Texas, N.A. (the "Bank"). The 1996 Credit Facility provides a revolving line of credit with the availability of funds and letters of credit being subject to a borrowing base determination at least semiannually. The borrowing base provides a maximum availability of $50.0 million (which amount is also the initial borrowing base), $100,000 of which was outstanding at December 31, 1996. Availability under the borrowing base is initially limited to $20.0 million for working capital and $30.0 million for acquisitions of oil and gas properties meeting certain criteria established by the Bank. Borrowings under the 1996 Credit Facility bear interest, at the Company's option, at a floating rate which is at or above the NationsBank, N.A. prime rate or the LIBOR rate, depending on the percentage of committed funds which have been borrowed. Interest is payable quarterly and principal will be amortized in twelve equal installments commencing two years from the date of the credit agreement. Under the 1996 Credit Facility, the Company is obligated to pay certain fees to the Bank, including a commitment fee which ranges from 0.30% to 0.40% based on the unused portion of the commitment. The 1996 Credit Facility contains customary restrictive covenants (including restrictions on the payment of dividends and the incurrence of additional indebtedness) and requires the Company to maintain a current ratio of not less than 1.0 to 1.0, a ratio of Adjusted EBITDA to interest expense of not less than 2.0 to 1.0 and a minimum tangible net worth. Borrowings under the 1996 Credit Facility are secured by substantially all of the assets of the Company and any subsidiary of the Company that guarantees the Company's obligations under the 1996 Credit Facility. Initially, none of the Company's subsidiaries have guaranteed the Company's obligations under the 1996 Credit Facility. In June, 1996, the Company entered into a loan agreement with NationsBridge, L.L.C. to provide financing of up to $125 million ("Bridge Loan"). The proceeds of this Bridge Loan were used to finance the 1996 Acquisition, to refinance the 1995 Credit Facility and for other general corporate purposes. The Company F-15 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS capitalized certain costs incurred in obtaining the Bridge Loan and amortized these costs over the estimated life of the Bridge Loan. Concurrent with the Offerings, the $2,665,000 remaining unamortized balance of these deferred charges were expensed as an extraordinary item. In June, 1995, the Company entered into a Credit Agreement ("1995 Credit Facility") with a syndicate of banks to provide financing for an aggregate $185 million senior secured revolving line of credit ("Revolver Notes") and an aggregate $15 million in senior secured term notes ("Term Notes"). In June 1996, these notes in a total amount of $71,494,000 were paid off with a portion of the proceeds of the Bridge Loan. The Company capitalized certain costs incurred in obtaining the 1995 Credit Facility and amortized these costs over the lives of the notes. Concurrent with the Bridge Loan, the $1,640,000 remaining unamortized balance of these deferred charges were expensed as an extraordinary item.

(8) INCOME TAXES Concurrent with the Offerings and upon consummation of the Corporate Reorganization, the Company became a tax paying entity for U.S. Federal income tax purposes. At that date, the tax basis of the Company's assets and liabilities exceeded the book basis by approximately $3,500,000, resulting in a deferred tax asset of approximately $1,200,000. A valuation allowance was provided for 100% of this deferred tax asset. Income tax provision (benefit), generated from $2,978,000 of net income before extraordinary item from the date of the Corporate Reorganization through December 31, 1996, and amounts separately allocated were as follows (thousands): Income (loss) before extraordinary item $ 1,218 Extraordinary loss resulting from early extinguishment of debt (1,042) -------- $ 176 -------- -------- The Company's effective tax rate does not differ materially from the U.S. Federal statutory rate. F-16 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities were as follows at December 31, 1996: Deferred tax assets: Net operating loss carryforwards $ 2,805 Interest rate swap agreements held for trading purposes 599 ------- Total gross deferred tax asset 3,404 ------- Deferred tax liabilities: Oil and gas properties, principally due to differences in depletion and the deduction of intangible drilling costs for tax purposes 1,692 ------- Net deferred tax asset 1,712 Valuation allowance of net deferred tax asset (1,712) ------- Net deferred tax asset, net of valuation allowance $ - ------- ------- A valuation is provided for when it is more likely than not that some portion of the deferred tax assets will not be realized. Due to uncertainties arising from a lack of earnings history and based on management's intentions to continue an aggressive drilling program (generating intangible drilling costs which are projected to create future losses for tax purposes), it does not appear more likely than not that the Company will be able to utilize all the available carryforwards prior to their ultimate expiration. At December 31, 1996, the Company had net operating loss carryforwards of approximately $8 million, which are available to offset future regular taxable income, if any. The carryforwards expire December 31, 2011. (9) COMMITMENTS AND CONTINGENCIES LEASES The Company leases equipment and office facilities under operating leases on which rental expense for the years ended December 31, 1996, 1995 and 1994 was $416,442, $311,221, and $197,533, respectively. Future minimum lease commitments under noncancellable operating leases at December 31, 1996 are as follows (thousands): 1997................................... $ 275,695 1998................................... 273,943 1999................................... 260,324 2000................................... 233,880 2001................................... 286,850 Thereafter............................. 1,395,886 EMPLOYMENT AGREEMENTS During the period from June through October, 1996, the Company entered into employment agreements with four of its executive officers. The employment agreements are each for three years and each will automatically renew for successive one-year periods thereafter unless the employee is notified to the contrary. These employment agreements provide for base annual salary levels totaling $990,000 for 1997. F-17 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Each employee would receive his salary for the remaining term of the applicable employment agreement if the Company were to terminate such person's employment other than for cause. If such person were to voluntarily leave his employment with the Company prior to the second anniversary of the employment agreement no further payments would be required. With the exception of one of the Company's executive officers, if a voluntary termination were to occur after the second anniversary of the employee agreement, such person would be entitled to one year's salary from the date of termination. With the exception of one of the Company's executive officers, the employee agreements provide that the covered employee will not compete with the Company for a one year period following his voluntary cessation of employment or termination of employment for cause, in either case if such event occurs within the initial three-year term of the employee agreement. EXPLORATION AND DEVELOPMENT In July 1995, the Republic of Moldova (located in Eastern Europe between Romania and the Ukraine) granted a Concession Agreement to Resource Development Company Limited, L.L.C. ("Redeco"), an entity not affiliated with the Company. The Company paid Redeco $90,000 and agreed to bear the first $2.0 million of Concession expenses in return for a 50.0% interest in Redeco. Upon reaching the $2.0 million in 1996, Redeco elected, according to the agreement, to pay the Company for half of all amounts expended in excess of $750,000 plus interest. The Concession Agreement covers the entire country with respect to oil and gas and other minerals and continues for various time periods depending on the nature of the activity conducted. The Company has no material fixed financial commitments with respect to the Concession. As of December 31, 1996, the Company's share of costs expended was $1,909,349. LETTERS OF CREDIT As a result of certain bonding and trade creditor requirements, the Company has caused irrevocable letters of credit to be issued by a bank totaling $96,000. As of December 31, 1996, no amounts had been drawn on these letters of credit. (10) 401(k) PLAN The Company has established a qualified cash or deferred arrangement under IRS code section 401(k) covering substantially all employees. Under the plan, the employees have an option to make elective contributions of a portion of their eligible compensation, not to exceed specified annual limitations, to the plan and the Company has an option to match a percentage of the employee's contribution. The Company has made matching contributions to the plan totaling $58,713, $22,531, and $8,921 in 1996, 1995 and 1994, respectively. (11) REDEEMABLE PREDECESSOR CAPITAL AND PREDECESSOR CAPITAL During 1995, NationsBanc Capital Corporation ("NBCC") contributed $10 million in exchange for a 30% ownership interest in the Company including the preferential return described below. Of this amount $1,266,000 was attributed to the non-redeemable portion of predecessor capital and $8,734,000 was attributed to redeemable predecessor capital. Preferred return and accretion of predecessor capital included in the consolidated statements of operations and the consolidated statements of stockholders' equity includes accretion of the amount attributable to redeemable predecessor capital to $10,000,000 over a two year period beginning February 17, 1995. As described below, the redemption amount was ultimately to be equal to $10,000,000 plus a preferred return and an additional redemption amount related to NBCC's redeemable interest not subject to preferential return. Concurrent with the Offerings, NBCC's membership interest was redeemed for a total of $15,506,614 and 936,000 common shares were issued to NBCC. After accounting for the Underwriter's exercise of its over- F-18 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS allotment option in November 1996, NBCC owns 8.94% of the 10,475,000 common shares outstanding at December 31, 1996. The following table details the redemption price paid to NBCC: NBCC Preferred Capital Contribution................. $10,000,000 Preferred Return.................................... 2,732,376 ----------- Adjusted NBCC Preferred Capital Contribution........ 12,732,376 PLUS: 10% Redemption Premium........................ 1,273,238 PLUS: Aggregate Redemption Price of NBCC's Redeemable Unrestricted Common Units.......... 1,500,000 ----------- Total Redemption Price Paid NBCC.................... $15,505,614 ----------- ----------- Redeemable predecessor capital was subject to a preferential return of 15% per annum and was redeemable at any time at the Company's option, subject to a redemption premium as described below, or at NBCC's option on February 17, 2003 or at an earlier date upon occurrence of certain events including a change in control, certain changes in management, a change in the Company's status as a limited liability company for tax purposes, or violation of any of various other restrictive provisions contained in the Regulations of Costilla Energy, Inc. (the "Regulations"). The 15% preferred return was treated as a reduction of predecessor capital. The redemption price to be paid by the Company was equal to the initial amount received for the preferred units plus a premium, determined in the year the units are purchased, as follows: Year after Premium February 17, 1995 Percentage ----------------- ---------- 1 10% 2 10% 3 8% 4 6% 5 4% 6 2% 7 0% 8 0% In addition, a portion of NBCC's interest not subject to preferential return was classified as redeemable predecessor capital as the Company could have been be required to repurchase such interest upon the occurrence of certain events similar to those events requiring redemption of the redeemable predecessor capital described above and, in any event, on or after February 17, 2000. Such interest could have, at the Company's option, been repurchased to the extent the Company has exercised its right to redeem all or a portion of the redeemable members' interest subject to the preferential return. The redemption price the Company would have paid in either instance would be determined by the year in which the predecessor capital was repurchased as follows: Before Aggregate February 17 Redemption Price ----------- ---------------- 1996 $ 1 1997 1,500,000 1998 3,000,000 1999 4,500,000 2000 5,500,000 F-19 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Prior to the Offerings in October 1996, the ultimate redemption price of $5,500,000 was being accrued ratably over the period from February 17, 1995 through February 17, 2000 and was treated as a reduction of predecessor capital. (12) STOCK-BASED COMPENSATION OUTSIDE DIRECTORS STOCK OPTION PLAN The Outside Directors Stock Option Plan provides for the issuance of stock options to the outside directors of the Company. A total of 50,000 shares has been authorized and reserved for issuance under the plan, subject to adjustments to reflect changes in the Company's capitalization resulting from stock splits, stock dividends and similar events. Only outside directors are eligible to participate in the plan. Outside directors are those directors of the Company who are not executive officers or regular salaried employees of the Company as of the date the Option is granted. Under the plan, an option for 1,000 shares of Common Stock will be granted to each person who qualifies as an outside director each year that such person is elected as a director of the Company. The exercise price of each option granted under the plan will be the fair market value (as reported on the Nasdaq National Market) of the Common Stock at the time the option is granted and may be paid either in cash, shares of Common Stock or a broker-assisted cashless transaction. Each option will be exercisable immediately, and will expire ten years from the date of grant. As of December 31, 1996, no options had been granted under this plan. BONUS INCENTIVE PLAN The Company has adopted the Bonus Incentive Plan, concurrent with the Offerings. The plan provides that the Board of Directors each year may award bonuses in cash, Common Stock, or some combination thereof, to those officers, directors, employees and advisors of the Company or a subsidiary of the Company, who the Board of Directors determines have contributed to the success of the Company. A total of 150,000 shares of Common Stock has been authorized and reserved for issuance under the plan, subject to adjustments to reflect changes in the Company's capitalization resulting from stock splits, stock dividends and similar events. All officers, directors, employees and advisors of the Company or a subsidiary of the Company who have completed a minimum of 180 days of service and are employed or retained by the Company or such subsidiary on the last day of the plan year, other than such persons who own ten percent or more of the outstanding shares of the Common Stock during that year, are eligible to participate in the plan. Bonus awards will be determined based upon a number of factors, including performance and salary level of the participant and the financial performance of the Company and its subsidiaries. Bonuses will be awarded after review and upon approval of the Board of Directors, subject to the terms and conditions of the plan. As of December 31, 1996, no shares of Common Stock have been issued pursuant to this plan. 1996 STOCK OPTION PLAN The 1996 Stock Option Plan provides for the grant of both incentive stock options and non-qualifying stock options, as well as limited stock appreciation rights and supplemental bonuses, to the employees of the Company and its subsidiaries, including officers and directors who are salaried employees. A total of 850,000 shares of Common Stock has been authorized and reserved for issuance under the plan, subject to adjustments to reflect changes in the Company's capitalization resulting from stock splits, stock dividends and similar events. The plan is administered by the Board of Directors. The Board of Directors has the sole authority to interpret the plan, to determine the persons to whom the options will be granted, to determine the basis upon which the options will be granted, and to determine the exercise price, duration and other terms of the options to be granted under the plan; provided that (a) the exercise price of each option granted under the plan may not be less than the fair market value of the Common Stock on the date the option is granted (and for incentive stock options, 110% of fair market value if the employee is the beneficial owner of 10% or more the Company's voting securities), (b) the exercise price must be paid in cash, by surrendering previously owned shares of Common Stock upon the exercise of the option or by a F-20 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS promissory note or broker-assisted cashless exercise approved by the Board of Directors, (c) the term of the option may not exceed ten years, and (d) no option is transferable other than by will, the laws of descent and distribution or pursuant to a qualified domestic relations order. Limited stock appreciation rights may be granted under the plan with respect to specified options, allowing the option holder to receive, in cash, the difference between the exercise price and the market value in the event of a change in control of the Company. The Board of Directors may also grant supplemental bonuses under the plan which are cash bonuses not to exceed the amount of income tax liability incurred by a plan participant upon the exercise of a non-qualifying stock option or a limited stock appreciation right with respect to which the bonus was granted. The Board of Directors may amend without stockholder approval, in any respect other than any amendment that requires stockholder approval by law, and may modify any outstanding option, including the repricing of non-qualifying options, with the consent of the option holder. There are currently approximately 100 employees who are eligible to participate in the plan. During 1996, the Company granted 711,750 stock options pursuant to the 1996 Stock Option Plan, leaving 138,250 options available for future grant under the plan as of December 31, 1996. The options granted during the year have a term of ten (10) years and an exercise price of $12.50 per share, a price equal to the market price on the date of the grant. The fair value, as calculated under the provision of SFAS 123, of the options granted in 1996 was $6.73 per share. The Company applies APB 25 and related Interpretations in accounting for its stock option awards. Accordingly, no compensation expense has been recognized for its stock option awards. If compensation expense for the stock option awards had been determined consistent with SFAS 123, the Company's net loss and net loss per share, for the year ended December 31, 1996 would have been adjusted to the following pro forma amounts: Net loss $(6,285,276) Net loss per share $ (0.97) The pro forma net loss and pro forma net loss per share amounts noted above are not likely to be representative of the pro forma amounts to be reported in future years. Pro forma adjustments in future years will include compensation expense associated with the options granted in 1996 plus compensation expense associated with any options awarded in future years. As a result, such pro forma compensation expense is likely to be higher than the levels reflected for 1996 if any options are awarded in future years. Under SFAS 123, the fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used for grants in 1996: Risk-free interest rate 6.25% Expected life 5 years Expected volatility 54% Expected dividend yield 0% (13) RELATED PARTY TRANSACTIONS Certain members and officers of the Company own interests in and hold positions with A&P Meter Service and Supply, Inc. ("A&P"), CSL, 511 Tex L.C. ("511 Tex"), and Valley. Advances from the Company to A&P have been consolidated into two promissory notes. The first note, which was originally executed December 31, 1994, totals $390,000, including accrued interest of $20,000 at December 31, 1996. The note bears interest at a floating rate equal to the "prime rate" plus 1.0%. No principal or interest payments are due until the maturity of the note at December 31, 2004. The note is secured by a second lien on A&P's accounts receivable, inventory and equipment. The second note is in the amount of $294,000, F-21 COSTILLA ENERGY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS including accrued interest of $47,000, and is dated May 22, 1996. The note bears interest at 6.0% per annum, is unsecured and is payable upon demand. During 1996, the Company paid $520,519 to A&P for goods and services provided. During 1995, the Company paid $612,139 to A&P for goods and services provided. During 1996, 1995 and 1994, the Company paid $517,352, $592,920 and $549,620, respectively, to CSL for management fees and lease payments on equipment. During 1996, the Company paid $50,742 to 511 Tex for office rent. During 1995, the Company paid $67,896 to 511 Tex for office rent. During 1996, 1995 and 1994 the Company paid $484,000, $440,884 and $2,458, respectively, to Valley for gas compression and salt water disposal charges. During 1996, Valley paid the Company $383,139 for operating costs of its salt water disposal wells and gas compressors. During 1995, Valley paid the Company $109,399 for operating costs of its salt water disposal wells and gas compressors. On December 31, 1996, certain officers and related party entities owed the Company $321,310 plus accrued interest of $1,431. During March 1997, the Company has received full payment for these amounts. During 1996 and 1995 the LLC paid $75,000 each year to NationsBank Capital Corp. for management fees. No management fees are due to NationsBank Capital Corp. for any period subsequent to the Offerings. (14) SUBSEQUENT EVENTS On January 1, 1997 Costilla Petroleum Corporation was merged into its parent, Costilla Energy, Inc. and Costilla Energy, Inc. assumed the business, assets and liabilities of Costilla Petroleum Corporation. The merger was effected for administrative purposes and to further reflect the Corporate Reorganization whereby business will be conducted through the Company rather than its predecessor, Costilla Energy, L.L.C. On March 1, 1997 Valley Gathering Company was merged into its parent, Costilla Energy, Inc. and Costilla Energy, Inc. assumed the business, assets and liabilities of Valley Gathering Company. The merger was effected for administrative purposes and to further reflect the Corporate Reorganization whereby business will be conducted through the Company rather than its predecessor, Costilla Energy, L.L.C. On March 5, 1997 Statewide was dissolved. This dissolution was effected for administrative purposes subsequent to the sale on December 31, 1996 of substantially all of the assets of Statewide for net proceeds of approximately $3.0 million. The remaining unsold producing oil and gas property was transferred to its parent, Costilla Energy, Inc., on December 31, 1996. On March 6, 1997, the Company sold its 40.5% interest in a Delaware limited liability company which owns and operates a gas pipeline and associated facilities in Louisiana. This membership interest had been held for resale. The Company sold its interest to another member of the limited liability company for $1,071,150. This amount represented the Company's actual investment of $1,019,771 plus interest of $51,379 since the date of the Company's original investment in April, 1996. The effective date of the sale was the date of the Company's original investment in April, 1996. The Company received a cash payment of $918,184 on March 6, 1997. In addition, the Company received a $152,966 note due in full on July 1, 1997 plus interest at 5.62%. F-22 COSTILLA ENERGY, INC.

Reserves were estimated in accordance with guidelines established by the SEC and FASB which require that reserve estimates be prepared under existing economic and operating conditions with no provision for price and cost escalations except by contractual arrangements. The Company has presented the reserve estimates utilizing an oil price of $24.17 per Bbl and a gas price of $3.96 per Mcf as of December 31, 1996 and an oil price of $17.79 per Bbl and a gas price of $2.03 per Mcf as of December 31, 1995. OIL AND GAS PRODUCING ACTIVITIES Oil and gas reserve quantity estimates are subject to numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. The accuracy of such estimates is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of subsequent drilling, testing and production may cause either upward or downward revision of previous estimates. Further, the volumes considered to be commercially recoverable fluctuate with changes in prices and operating costs. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise than those of currently producing oil and gas properties. Accordingly, these estimates are expected to change as additional information becomes available in the future. F-23 COSTILLA ENERGY, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL AND GAS RESERVES The 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 proved oil and gas reserves less estimated future expenditures (based on year-end costs) to be incurred in developing and producing the proved reserves, less estimated future income tax expenses (based on year-end statutory tax rates, with consideration of future tax rates already legislated) to be incurred on pretax net cash flows less tax basis of the properties and available credits, and assuming continuation of existing economic conditions. The estimated future net cash flows are then discounted using a rate of 10% per year to reflect the estimated timing of the future cash flows. Discounted future cash flow estimates like those shows below are not intended to represent estimates of the fair value of oil and gas properties. Estimates of fair value should also consider probable reserves, anticipated future oil and gas prices, interest rates, changes in development and production costs and risks associated with future production. Because of these and other considerations, any estimate of fair value is necessarily subjective and imprecise.
