The following documents are incorporated by reference into the indicated parts of this Annual Report on Form 10-K: None Parts I and II of this Report contain forward looking statements that involve risks and uncertainties. Accordingly, no assurances can be given that the actual events and results will not be materially different than the anticipated results described in the forward looking statements. See "Item 1. Business" for a description of various factors that could materially affect the ability of the Partnership to achieve the anticipated results described in the forward looking statements. PART I ITEM 1. Business Parker & Parsley 90-A, L.P. (the "Partnership") is a limited partnership organized in 1990 under the laws of the State of Delaware. As of August 8, 1997, Pioneer Natural Resources USA, Inc. ("Pioneer USA") became the managing general partner of the Partnership. Prior to August 8, 1997, the Partnership's managing general partner was Parker & Parsley Development L.P. ("PPDLP"), a wholly-owned subsidiary of Parker & Parsley Petroleum Company ("Parker & Parsley"). On August 7, 1997, Parker & Parsley and Mesa Inc. ("Mesa") received shareholder approval to merge and create Pioneer Natural Resources Company ("Pioneer"). On August 8, 1997, PPDLP was merged with and into Pioneer USA, a wholly-owned subsidiary of Pioneer, resulting in Pioneer USA becoming the managing general partner of the Partnership as PPDLP's successor by merger. For a more complete description of the Parker & Parsley and Mesa merger, see Pioneer's Registration Statement on Form S-4 as filed with the Securities & Exchange Commission. A Registration Statement, as amended, filed pursuant to the Securities Act of 1933, registering limited partnership interests aggregating $70,000,000 in a series of Delaware limited partnerships formed under the Parker & Parsley 89-90 Development Drilling Program, was declared effective by the Securities and Exchange Commission on August 1, 1989. On April 30, 1990, the offering of limited partnership interests in the Partnership, the third partnership formed under such registration statement, was closed, with interests aggregating $6,811,000 being sold to 525 subscribers. The Partnership engages primarily in oil and gas development and production and is not involved in any industry segment other than oil and gas. See "Item 6. Selected Financial Data" and "Item 8. Financial Statements and Supplementary Data" of this report for a summary of the Partnership's revenue, income and identifiable assets. The principal markets during 1997 for the oil produced by the Partnership were refineries and oil transmission companies that have facilities near the Partnership's oil producing properties. The principal markets for the Partnership's gas were companies that have pipelines located near the Partnership's gas producing properties. Of the Partnership's total oil and gas revenues for 1997, approximately 58% and 19% were attributable to sales made to Genesis Crude Oil, L.P. and Western Gas Resources, Inc., respectively. The Partnership's revenues, profitability, cash flow and future rate of growth are highly dependent on the prevailing prices of oil and gas, which are affected by numerous factors beyond the Partnership's control. Oil and gas prices historically have been very volatile. A substantial or extended decline in the prices of oil or gas could have a material adverse effect on the Partnership's 2 revenues, profitability and cash flow and could, under certain circumstances, result in a reduction in the carrying value of the Partnership's oil and gas properties. Because of the demand for oil and gas, the Partnership does not believe that the termination of the sales of its products to any one customer would have a material adverse impact on its operations. The loss of a particular customer for gas may have an effect if that particular customer has the only gas pipeline located in the areas of the Partnership's gas producing properties. The Partnership believes, however, that the effect would be temporary, until alternative arrangements could be made. Federal and state regulation of oil and gas operations generally includes the fixing of maximum prices for regulated categories of natural gas, the imposition of maximum allowable production rates, the taxation of income and other items, and the protection of the environment. Although the Partnership believes that its business operations do not impair environmental quality and that its costs of complying with any applicable environmental regulations are not currently significant, the Partnership cannot predict what, if any, effect these environmental regulations may have on its current or future operations. The Partnership does not have any employees of its own. Pioneer USA employs 1,133 persons, many of whom dedicated a part of their time to the conduct of the Partnership's business during the period for which this report is filed. Pioneer USA is responsible for all management functions. Numerous uncertainties exist in estimating quantities of proved reserves and future net revenues therefrom. The estimates of proved reserves and related future net revenues set forth in this report are based on various assumptions, which may ultimately prove to be inaccurate. Therefore, such estimates should not be construed as estimates of the current market value of the Partnership's proved reserves. No material part of the Partnership's business is seasonal and the Partnership conducts no foreign operations. ITEM 2. Properties The Partnership's properties consist primarily of leasehold interests in properties on which oil and gas wells are located. Such property interests are often subject to landowner royalties, overriding royalties and other oil and gas leasehold interests. Fractional working interests in developmental oil and gas prospects located primarily in the Spraberry Trend Area of West Texas were acquired by the Partnership, resulting in the Partnership's participation in the drilling of 27 oil and gas wells. Two wells have been sold; one in 1996 and one in 1993. At December 31, 1997, 25 wells were producing. For information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1997, 1996 and 1995 and changes in such quantities for the years then ended, see Note 7 of Notes to Financial Statements included in "Item 8. Financial Statements and Supplementary Data" below. Such reserves have been estimated by the engineering staff of Pioneer USA with a review by an independent petroleum consultant. 3 ITEM 3. Legal Proceedings The Partnership is a party to various legal proceedings incidental to its business involving claims in oil and gas leases or interests, other claims for damages in amounts not in excess of 10% of its current assets and other matters, none of which Pioneer believes to be material. ITEM 4. Submission of Matters to a Vote of Security Holders There were no matters submitted to a vote of security holders during the fourth quarter of 1997. 4 PART II ITEM 5. Market for Partnership's Common Equity and Related Stockholder Matters At March 9, 1998, the Partnership had 6,811 outstanding limited partnership interests held of record by 525 subscribers. There is no established public trading market for the limited partnership interests. Under the limited partnership agreement, Pioneer USA has made certain commitments to purchase partnership interests at a computed value. Revenues which, in the sole judgement of the managing general partner, are not required to meet the Partnership's obligations are distributed to the partners at least quarterly in accordance with the limited partnership agreement. During the years ended December 31, 1997 and 1996, $361,394 and $366,110, respectively, of such revenue-related distributions were made to the limited partners. ITEM 6.

Management's Discussion and Analysis of Financial Condition and Results of Operations Results of Operations 1997 compared to 1996 The Partnership's 1997 oil and gas revenues decreased 17% to $643,882 from $777,677 in 1996. The decrease in revenues resulted from declines in production and lower average prices received. In 1997, 21,972 barrels of oil, 4,763 barrels of natural gas liquids ("NGLs") and 68,973 mcf of gas were sold, or 38,231 barrel of oil equivalents ("BOEs"). In 1996, 25,428 barrels of oil and 88,919 mcf of gas were sold, or 40,248 BOEs. Consistent with the managing general partner, the Partnership has historically accounted for processed natural gas production as wellhead production on a wet gas basis. As a result of the merger with Mesa, the managing general partner has adopted Mesa's accounting policy and now accounts for processed natural gas production in two components: natural gas liquids and dry residue gas. As a result of the change in the managing general partner's policy, the Partnership now accounts for processed natural gas production as processed natural gas liquids and dry residue gas. Consequently, separate product volumes will not be comparable for periods prior to September 30, 1997. The declines in production volumes were primarily attributable to the decline characteristics of the Partnership's oil and gas properties. Because of these characteristics, management expects a certain amount of decline in production to continue in the future until the Partnership's economically recoverable reserves are fully depleted. The average price received per barrel of oil decreased 10% from $21.62 in 1996 to $19.41 in 1997. The average price received per barrel of NGLs during 1997 was $11.16. The average price received per mcf of gas decreased 7% in 1997 to $2.38 compared to $2.56 in 1996. The market price for oil and gas has been extremely volatile in the past decade, and management expects a certain amount of volatility to continue in the foreseeable future. The Partnership may therefore sell its future oil and gas production at average prices lower or higher than that received in 1997. Total costs and expenses increased in 1997 to $801,240 as compared to $523,562 in 1996, an increase of $277,678, or 53%. This increase was primarily due to the impairment of oil and gas properties and an increase in production costs, offset by declines in loss on disposition of assets, depletion and general and administrative expenses ("G&A"). Production costs were $305,774 in 1997 and $298,749 in 1996, resulting in a $7,025 increase. The increase was due to additional well maintenance costs, offset by a decrease in production taxes. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A decreased, in aggregate, 9% from $26,252 in 1996 to $23,842 in 1997. The Partnership paid the managing general partner $20,526 in 1997 and $22,989 in 1996 for G&A incurred on behalf of the Partnership. G&A is allocated, in part, to the Partnership by the managing general partner. Such allocated expenses are determined by the managing general partner based upon its judgement of the level 6 of activity of the Partnership relative to the managing general partner's activities and other entities it manages. The method of allocation has varied in certain years and may do so again depending on the activities of the managed entities. The Partnership adopted Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121") effective as of October 1, 1995 (see Notes 2 and 3 of Notes to Financial Statements included in "Item 8. Financial Statements and Supplementary Data"). As a result of the review and evaluation of its long-lived assets for impairment, the Partnership recognized a non-cash charge of $321,019 related to its oil and gas properties during the fourth quarter of 1997. Depletion was $150,605 in 1997 compared to $169,844 in 1996. This represented a decrease of $19,239, or 11%. This decrease was primarily attributable to a decline in oil production of 3,456 barrels from 1996. A loss on disposition of assets of $28,717 was recognized during 1996 resulting from the sale of one gas well and the write-off of remaining capitalized well costs of $35,532 less proceeds received of $6,815. 1996 compared to 1995 The Partnership's 1996 oil and gas revenues increased 18% to $777,677 from $661,198 in 1995. The increase in revenues resulted from a 26% increase in the average price received per barrel of oil and a 50% increase in the average price received per mcf of gas, offset declines in barrels of oil and mcf of gas produced and sold. In 1996, 25,428 barrels of oil were sold compared to 27,823 in 1995, a decrease of 2,395 barrels, or 9%. In 1996, 88,919 mcf of gas were sold compared to 107,613 in 1995, a decrease of 18,694 mcf, or 17%. Of this decrease, 10,464 mcf, or 10%, was attributable to the sale of one gas well during 1996. The remainder of the decrease, 8,230 mcf or 7%, was due to the decline characteristics of the Partnership's oil and gas properties. The average price received per barrel of oil increased $4.45 from $17.17 in 1995 to $21.62 in 1996. The average price received per mcf of gas increased in 1996 to $2.56 compared to $1.71 in 1995. Total costs and expenses decreased in 1996 to $523,562 as compared to $1,365,678 in 1995, a decrease of $842,116, or 62%. This decrease was due to declines in impairment of oil and gas properties, production costs, depletion and amortization of organization costs, offset by increases in G&A and loss on sale of assets. Production costs were $298,749 in 1996 and $331,241 in 1995, resulting in a $32,492 decrease, or 10%. The decrease was due to a decline in well maintenance costs and lower ad valorem taxes, offset by an increase in production taxes. During this period, G&A increased, in aggregate, 10% from $23,890 in 1995 to $26,252 in 1996. The Partnership paid the managing general partner $22,989 in 1996 and $19,345 in 1995 for G&A incurred on behalf of the Partnership. The Partnership adopted SFAS 121 effective as of October 1, 1995 (see Notes 2 and 3 of Notes to Financial Statements included in "Item 8. Financial Statements and Supplementary Data"). As a result of the review and evaluation of its long-lived assets for impairment, the Partnership recognized a non-cash charge of $583,706 related to its oil and gas properties during the fourth quarter of 1995. 7 Depletion was $169,844 in 1996 compared to $425,884 in 1995. This represented a decrease of $256,040, or 60%. This decrease was primarily attributable to the following factors: (i) a reduction in the Partnership's net depletion basis from charges taken in accordance with SFAS 121, (ii) a reduction of 2,395 barrels from 1995, and (iii) an increase in oil and gas reserves during 1996 as a result of higher commodity prices. A loss on disposition of assets of $28,717 was recognized during 1996 resulting from the sale of one gas well and the write-off of remaining capitalized well costs of $35,532 less proceeds received of $6,815. Impact of inflation and changing prices on sales and net income Inflation impacts the fixed overhead rate charges of the lease operating expenses for the Partnership. During 1995, the annual change in the index of average weekly earnings of crude petroleum and gas production workers issued by the U.S. Department of Labor, Bureau of Labor Statistics increased by 4.4%. The 1996 annual change in the average weekly earnings increased by 4.1%. The 1997 index (effective April 1, 1997) increased 2%. The impact of inflation for other lease operating expenses is small due to the current economic condition of the oil industry. The oil and gas industry experienced volatility during the past decade because of the fluctuation of the supply of most fossil fuels relative to the demand for such products and other uncertainties in the world energy markets causing significant fluctuations in oil and gas prices. During 1997, the price per barrel for oil production similar to the Partnership's ranged from approximately $16.00 to $23.00. During most of 1997 and 1996, the Partnership benefitted from higher oil prices as compared to previous years. However, during the fourth quarter of 1997, oil prices began a downward trend that has continued into March 1998. On March 19, 1998, the market price for West Texas intermediate crude was $12.00 per barrel. A continuation of the oil price environment experienced during the first quarter of 1998 will have an adverse effect on the Partnership's revenues and operating cash flow and could result in additional decreases in the carrying value of the Partnership's oil and gas properties. Prices for natural gas are subject to ordinary seasonal fluctuations, and this volatility of natural gas prices may result in production being curtailed and, in some cases, wells being completely shut-in. Liquidity and capital resources Net Cash Provided by Operating Activities Net cash provided by operating activities decreased $4,961 during the year ended December 31, 1997 from the year ended December 31, 1996, attributable to a decrease in oil and gas receipts, offset by a decline in production costs paid. Net Cash Provided by (Used in) Investing Activities The Partnership's investing activities during 1997 and 1996 were for expenditures related to oil and gas equipment replacement on active properties. One gas well was sold during 1996, resulting in the receipt of $6,815 in proceeds from the sale. 8 Net Cash Used in Financing Activities Cash was sufficient in 1997 for distributions to the partners of $365,044 of which $3,650 was distributed to the managing general partner and $361,394 to the limited partners. In 1996, cash was sufficient for distributions to the partners of $369,808 of which $3,698 was distributed to the managing general partner and $366,110 to the limited partners. It is expected that future net cash provided by operations will be sufficient for any capital expenditures and any distributions. As the production from the properties declines, distributions are also expected to decrease. Information systems for the year 2000 The general partner will be required to modify its information systems in order to accurately process Partnership data referencing the year 2000. Because of the importance of occurrence dates in the oil and gas industry, the consequences of not pursuing these modifications could be very significant to the Partnership's ability to manage and report operating activities. Currently, the general partner plans to contract with third parties to perform the software programming changes necessary to correct any existing deficiencies. Such programming changes are anticipated to be completed and tested by March 1, 1999. The managing general partner will allocate a portion of the costs of the year 2000 programming charges to the Partnership when they are incurred, along with recurring general and administrative expenses as defined pursuant to the partnership agreement. Although the costs are not estimable at this time, they should not be significant to the Partnership. 9 ITEM 8.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS December 31, 1997, 1996 and 1995 Note 1. Organization and nature of operations Parker & Parsley 90-A, L.P. (the "Partnership") is a limited partnership organized in 1990 under the laws of the State of Delaware. As of August 8, 1997, Pioneer Natural Resources USA, Inc. ("Pioneer USA") became the managing general partner of the Partnership. Prior to August 8, 1997, the Partnership's managing general partner was Parker & Parsley Development L.P. ("PPDLP"), a wholly-owned subsidiary of Parker & Parsley Petroleum Company ("Parker & Parsley"). On August 7, 1997, Parker & Parsley and Mesa Inc. received shareholder approval to merge and create Pioneer Natural Resources Company ("Pioneer"). On August 8, 1997, PPDLP was merged with and into Pioneer USA, a wholly-owned subsidiary of Pioneer, resulting in Pioneer USA becoming the managing general partner of the Partnership as PPDLP's successor by merger. The Partnership engages primarily in oil and gas development and production in the Spraberry Trend area of West Texas and is not involved in any industry segment other than oil and gas. Note 2. Summary of significant accounting policies A summary of the significant accounting policies consistently applied in the preparation of the accompanying financial statements follows: The Partnership accounts for long-lived assets to be disposed of at the lower of their carrying amount or fair value less costs to sell once management has committed to a plan to dispose of the assets. Oil and gas properties - The Partnership utilizes the successful efforts method of accounting for its oil and gas properties and equipment. Under this method, all costs associated with productive wells and nonproductive development wells are capitalized while nonproductive exploration costs are expensed. Capitalized costs relating to proved properties are depleted using the unit-of-production method on a property-by-property basis based on proved oil (dominant mineral) reserves as determined by the engineering staff of Pioneer USA, the Partnership's managing general partner, and reviewed by independent petroleum consultants. The carrying amounts of properties sold or otherwise disposed of and the related allowances for depletion are eliminated from the accounts and any gain or loss is included in operations. Impairment of long-lived assets - In accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121"), the Partnership reviews its long-lived assets to be held and used on an individual property basis, including oil and gas properties accounted for under the successful efforts method of accounting, whenever events or circumstances 16 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 is less than the carrying amount of the assets. In this circumstance, the Partnership recognizes an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Use of estimates in the preparation of financial statements - Preparation of the accompanying 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 reporting amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Organization costs - Organization costs are capitalized and amortized on the straight-line method over 60 months. Net income (loss) per limited partnership interest - The net income (loss) per limited partnership interest is calculated by using the number of outstanding limited partnership interests. Income taxes - A Federal income tax provision has not been included in the financial statements as the income of the Partnership is included in the individual Federal income tax returns of the respective partners. Statements of cash flows - For purposes of reporting cash flows, cash and cash equivalents include depository accounts held by banks. General and administrative expenses - General and administrative expenses are allocated in part to the Partnership by the managing general partner or its affiliates. Such allocated expenses are determined by the managing general partner based upon its judgement of the level of activity of the Partnership relative to the managing general partner's activities and other entities it manages. The method of allocation has varied in certain years and may do so again depending on the activities of the managed entities. Environmental - The Partnership 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 Partnership 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. Such liabilities are generally undiscounted unless the timing of cash payments for the liability or component are fixed or reliably determinable. Note 3. Impairment of long-lived assets The Partnership adopted SFAS 121 effective October 1, 1995. In order to determine whether an impairment has occurred, the Partnership estimates the expected future cash flows of its oil and gas properties and compares such 17 future cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. For those oil and gas properties for which the carrying amount exceeded the estimated future cash flows, an impairment was determined to exist; therefore, the Partnership adjusted the carrying amount of those oil and gas properties to their fair value as determined by discounting their expected future cash flows at a discount rate commensurate with the risks involved in the industry. As a result of the review and evaluation of its long-lived assets for impairment, the Partnership recognized non-cash charges of $321,019 and $583,706 related to its oil and gas properties during the fourth quarters of 1997 and 1995, respectively. Note 4. Income taxes The financial statement basis of the Partnership's net assets and liabilities was $669,632 greater than the tax basis at December 31, 1997.

Oil and gas information (unaudited) The following table presents information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1997, 1996 and 1995 and changes in such quantities during the years then ended. All of the Partnership's reserves are proved and located within the United States. The Partnership's reserves are based on an evaluation prepared by the engineering staff of Pioneer USA and reviewed by an independent petroleum consultant, using criteria established by the Securities and Exchange Commission. Reserve value information is available to limited partners pursuant to the Partnership agreement and therefore, is not presented. Oil and NGLs Gas (bbls) (mcf) ------------ ---------- Net proved reserves at January 1, 1995 358,202 1,388,538 Revisions (21,993) 24,720 Production (27,823) (107,613) ------------ ---------- Net proved reserves at December 31, 1995 308,386 1,305,645 Revisions 60,341 363,559 Sale of reserves (141) (51,479) Production (25,428) (88,919) ------------ ---------- Net proved reserves at December 31, 1996 343,158 1,528,806 Revisions 81,982 (865,758) Production (26,735) (68,973) ------------ ---------- Net proved reserves at December 31, 1997 398,405 594,075 ============ ========== The estimated present value of future net revenues of proved reserves, calculated using December 31, 1997 prices of $17.16 per barrel of oil, $12.50 per barrel of NGLs and $2.14 per mcf of gas, discounted at 10% was approximately $1,617,000 and undiscounted was $2,856,000 at December 31, 1997. Subsequent to December 31, 1997, the prices or oil and gas have been declining, and on March 19, 1998, the average prices for the Partnership's oil and gas were approximately $12.00 and $2.05, respectively. The Partnership emphasizes that reserve estimates are inherently imprecise and, accordingly, the estimates are expected to change as future information becomes available. Note 8. Major customers The following table reflects the major customers of the Partnership's oil and gas sales (a major customer is defined as a customer whose sales exceed 10% of total sales) during the years ended December 31: 1997 1996 1995 ------- ------- ------- Genesis Crude Oil, L.P. 58% 61% 63% Western Gas Resources, Inc. 19% 14% 12% GPM Gas Corporation - - 10% The above customers represent 61% of total accounts receivable at December 31, 1997. 20 Pioneer USA is party to a long-term agreement pursuant to which Pioneer USA and affiliates are to sell to Basis Petroleum, Inc. (formerly Phibro Energy, Inc.)substantially all crude oil (including condensate) which any of such entities have the right to market from time to time. On November 25, 1996, Pioneer USA consented to the assignment of the agreement to Genesis Crude Oil, L.P. ("Genesis"), a limited partnership formed by Basis Petroleum, Inc. and Howell Corporation. The price to be paid by Genesis for oil purchased under the agreement ("Genesis Agreement") is to be competitive with prices paid by other substantial purchasers in the same areas who are significant competitors of Genesis. The price to be paid for oil purchased under the Genesis Agreement includes a market-related bonus that may vary from month to month based upon spot oil prices at various commodity trade points. The term of the Genesis Agreement is through June 30, 1998, and it may continue thereafter subject to termination rights afforded each party. Salomon, Inc., the parent company of Basis Petroleum, Inc. and a subordinated limited partner in Genesis, secures the payment obligations under the Genesis Agreement with a $25 million payment guarantee. Accounts receivable-oil and gas sales included $31,161 due from Genesis at December 31, 1997. Note 9. Organization and operations The Partnership was organized April 30, 1990 as a limited partnership under the Delaware Act for the purpose of acquiring and developing oil and gas properties. The following is a brief summary of the more significant provisions of the limited partnership agreement: Managing general partner - The managing general partner of the Partnership is Pioneer USA. Pioneer USA has the power and authority to manage, control and administer all Program and Partnership affairs. Under the limited partnership agreement, the managing general partner pays 1% of the Partnership's acquisition, drilling and completion costs and 1% of its operating and general and administrative expenses. In return, it is allocated 1% of the Partnership's revenues. Limited partner liability - The maximum amount of liability of any limited partner is the total contributions of such partner plus his share of any undistributed profits. Initial capital contributions - The limited partners entered into subscription agreements for aggregate capital contributions of $6,811,000. Pioneer USA is required to contribute amounts equal to 1% of initial Partnership capital less commission and organization and offering costs allocated to the limited partners and to contribute amounts necessary to pay costs and expenses allocated to it under the Partnership agreement to the extent its share of revenues does not cover such costs. Note 10. Disposition of Assets Loss on disposition of assets was due to a loss of $28,717 on sale of assets during 1996. This loss was the result of the write-off of remaining capitalized well costs for one gas well of $35,532, less proceeds received of $6,815. 21 ITEM 9.
