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-C Conv., L.P. (the "Partnership") is a general partnership organized in 1990 under the laws of the State of Texas. The Partnership converted to a Delaware limited partnership on August 1, 1991. 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. A Registration Statement, as amended, filed pursuant to the Securities Act of 1933, registering general partnership interests aggregating $30,000,000 in a series of Texas general 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 December 28, 1990, the offering of general partnership interests in the Partnership, the fifth partnership formed under such registration statement, was closed, with interests aggregating $7,531,000 being sold to 517 subscribers. The Partnership engages 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" for a summary of the Partnership's oil and gas sales, net income and identifiable assets. The principal markets during 1999 for the oil produced by the Partnership were refineries and oil transmission companies that have facilities near the Partnership's oil producing properties. During 1999, Pioneer USA marketed the Partnership's gas to a variety of purchasers, none of which accounted for 10% or more of the Partnership's oil and gas revenues. Of the Partnership's total oil and gas revenues for 1999, approximately 62% was attributable to sales made to Plains All American Inc. Pioneer USA is of the opinion that the loss of any one purchaser would not have an adverse effect on its ability to sell its oil and gas production or natural gas products. 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 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. 2 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 687 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 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 44 oil and gas wells. One well was sold and one well was plugged and abandoned due to uneconomical operations. At December 31, 1999, the Partnership had 42 producing oil and gas wells. For information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1999, 1998 and 1997 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 Williamson Petroleum Consultants, Inc., an independent petroleum consultant. ITEM 3. Legal Proceedings The Partnership from time to time 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 USA believes to be material to the Partnership. 3 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 1999. 4 PART II ITEM 5. Market for Partnership's Common Equity and Related Stockholder Matters At March 8, 2000, the Partnership had 7,531 outstanding limited partnership interests held of record by 508 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, 1999 and 1998, $135,825 and $130,281, 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 1999 compared to 1998 The Partnership's 1999 oil and gas revenues increased 25% to $537,893 from $430,499 in 1998. The increase in revenues resulted from higher average prices received, offset by a decline in production. In 1999, 23,568 barrels of oil, 9,050 barrels of natural gas liquids ("NGLs") and 29,399 mcf of gas were sold, or 37,518 barrel of oil equivalents ("BOEs"). In 1998, 24,493 barrels of oil, 8,694 barrels of NGLs and 30,348 mcf of gas were sold, or 38,245 BOEs. Due to the decline characteristics of the Partnership's oil and gas properties, management expects a certain amount of decline in production in the future until the Partnership's economically recoverable reserves are fully depleted. The average price received per barrel of oil increased $3.89, or 29%, from $13.24 in 1998 to $17.13 in 1999. The average price received per barrel of NGLs increased $2.51, or 37%, from $6.80 in 1998 to $9.31 in 1999. The average price received per mcf of gas increased 10% from $1.55 in 1998 to $1.70 in 1999. 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 received in 1999. The volatility of commodity prices has had, and continues to have, a significant impact on the Partnership's revenues and operating cash flow and could result in additional decreases to the carrying value of the Partnership's oil and gas properties. Total costs and expenses decreased in 1999 to $405,150 compared to $693,871 in 1998, a decrease of $288,721, or 42%. This decrease was due to declines in the impairment of oil and gas properties, depletion and production costs, offset by an increase in general and administrative expenses ("G&A"). Production costs were $297,353 in 1999 and $314,363 in 1998, resulting in a decrease of $17,010, or 5%. The decrease was due to declines in well maintenance costs and ad valorem taxes, offset by an increase 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 increased, in aggregate, 39% from $15,084 in 1998 to $20,987 in 1999. The Partnership paid the managing general partner $16,060 in 1999 and $12,838 in 1998 for G&A incurred on behalf of the Partnership. G&A is allocated, in part, to the Partnership by the managing general partner. Allocated expenses are determined by the managing general partner based upon the level of activity of the Partnership relative to the non-partnership activities of the managing general partner. The method of allocation has been consistent over the past several years with certain modifications incorporated to reflect changes in Pioneer USA's overall business activities. 6 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 managing general partner reviews the Partnership's oil and gas properties for impairment whenever events or circumstances indicate a decline in the recoverability of the carrying value of the Partnership's assets may have occurred. As a result of the review and evaluation of its long-lived assets for impairment, the Partnership recognized a non-cash charge of $185,784 related to its oil and gas properties during 1998. Depletion was $86,810 in 1999 compared to $178,640 in 1998. This represented a decrease of $91,830, or 51%. This decrease was primarily the result of a combination of factors that included an increase in proved reserves during 1999 due to higher commodity prices, a reduction in the Partnership's net depletable basis from charges taken in accordance with SFAS 121 during the fourth quarter of 1998 and a decline in oil production of 925 barrels for the period ended December 31, 1999 compared to the same period in 1998. 1998 compared to 1997 The Partnership's 1998 oil and gas revenues decreased 35% to $430,499 from $661,475 in 1997. The decrease in revenues resulted from lower average prices received. In 1998, 24,493 barrels of oil, 8,694 barrels of NGLs and 30,348 mcf of gas were sold, or 38,245 BOEs. In 1997, 25,817 barrels of oil, 3,661 barrels of NGLs and 50,304 mcf of gas were sold, or 37,862 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. Effective September 30, 1997, as a result of the merger with Mesa, the managing general partner 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. Also, prices for gas products will not be comparable as the price per mcf for natural gas for the year ended December 31, 1998 is the price received for dry residue gas and the price per mcf for natural gas produced prior to October 1997 was presented as a price for wet gas (i.e., natural gas liquids combined with dry residue gas). The average price received per barrel of oil decreased $6.24, or 32%, from $19.48 in 1997 to $13.24 in 1998. The average price received per barrel of NGLs decreased $3.78, or 36%, from $10.58 in 1997 to $6.80 in 1998. The average price received per mcf of gas decreased 35% from $2.38 in 1997 to $1.55 in 1998. Total costs and expenses increased in 1998 to $693,871 compared to $562,477 in 1997, an increase of $131,394, or 23%. This increase was due to increases in the impairment of oil and gas properties and depletion, offset by decreases in production costs and G&A. Production costs were $314,363 in 1998 and $331,332 in 1997, resulting in a decrease of $16,969, or 5%. The decrease was due to declines in production and ad valorem taxes and workover expense, offset by an increase in well maintenance costs incurred to stimulate well production. 7 During this period G&A decreased, in aggregate, 30% from $21,436 in 1997 to $15,084 in 1998. The Partnership paid the managing general partner $12,838 in 1998 and $17,703 in 1997 for G&A incurred on behalf of the Partnership. The Partnership recognized non-cash SFAS 121 charges of $185,784 and $79,288 related to its oil and gas properties during 1998 and 1997, respectively. Depletion was $178,640 in 1998 compared to $130,421 in 1997. This represented an increase of $48,219, or 37%. This increase was primarily the result of a combination of factors that included a decline in proved reserves during 1998 due to lower commodity prices, offset by a reduction in the Partnership's net depletable basis from charges taken in accordance with SFAS 121 during the fourth quarter of 1997 and a decline in oil production of 1,324 barrels for the period ended December 31, 1998 compared to the same period in 1997. Impact of inflation and changing prices on sales and net income Inflation generally does not impact revenues in the oil and gas industry. However, inflation generally does impact expenses, the most significant for the Partnership is lease operating expenses. The petroleum industry has been characterized by volatile oil, NGL and natural gas commodity prices and relatively stable supplier costs during the three years ended December 31, 1999. During 1997 and 1998, weather patterns, regional economic recessions and political matters combined to cause worldwide crude oil supplies to exceed demand. As a result, crude oil prices declined substantially from the price levels of 1996. Also during 1997 and 1998, but to a lesser extent, market prices for natural gas declined. During 1999, the price per barrel for oil production similar to the Partnership's ranged from approximately $11.00 to $24.00. The decrease in crude oil exports during 1999 by members of the Organization of Petroleum Exporting Countries ("OPEC") and other crude oil exporting nations has resulted in higher Partnership revenues and operating cash flow as compared to 1998. 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 increased $64,937 during the year ended December 31, 1999 from 1998. The increase was primarily attributable to an increase of $39,963 in oil and gas sales receipts and reductions in operating costs paid of $23,955 that have resulted from the managing general partner's cost containment measures and a decline in G&A expenses paid of $1,019. Net Cash Used in Investing Activities The Partnership's investing activities during 1999 and 1998 included expenditures related to equipment upgrades on active oil and gas properties. 8 Net Cash Used in Financing Activities In 1999, cash distributions to the partners were $137,197, of which $1,372 was distributed to the managing general partner and $135,825 to the limited partners. In 1998, cash distributions to the partners were $131,597, of which $1,316 was distributed to the managing general partner and $130,281 to the limited partners. Since the first quarter of 1999, world crude oil prices have increased, primarily as a result of decreases in crude oil supplies made available by OPEC and other crude oil exporting nations. During the period from the third quarter of 1997 through the first quarter of 1999, there was a significant declining trend in world oil prices and, to a lesser extent, natural gas prices. During the first quarter of 1999, OPEC and certain other crude oil exporting nations announced reductions in their planned export volumes. These announcements, together with the enactment of announced reductions in export volumes, have had a positive impact on world crude oil prices. No assurances can be given that the reductions in export volumes or the positive trend in oil and gas commodity prices can be sustained for an extended period of time. Proposal to acquire partnerships On September 8, 1999, Pioneer USA filed a preliminary proxy statement with the SEC proposing an agreement and plan of merger to the limited partners of 25 publicly-held Parker & Parsley limited partnerships. The preliminary proxy statement is non-binding and is subject to, among other things, consideration of offers from third parties to purchase any partnership or its assets, the majority approval of the limited partners in each partnership and the resolution of SEC review comments. Pioneer is continuing to evaluate the feasibility of the proposed agreement and plan of merger; however, the current commodity price outlook has diminished the likelihood that the proposed agreement and plan of merger will be consummated. Year 2000 project readiness As the year 2000 was approaching, the inability of some computer programs and embedded technologies to distinguish between "1900" and "2000" gave rise to the "Year 2000" problem. Such computer programs and related technology were at risk to fail outright or communicate inaccurate data, if not remediated or replaced. With the proliferation of electronic data interchange, the Year 2000 problem represented a significant exposure to the entire global community, the full extent of which could not be accurately assessed prior to the year 2000. In proactive response to the Year 2000 problem, the managing general partner established a "Year 2000" project that assessed, to the extent possible, the Partnership's and the managing general partner's internal Year 2000 problem; took remedial actions necessary to minimize the Year 2000 risk exposure to the managing general partner and significant third parties with whom it has data interchange; and, tested the managing general partner's systems and processes once remedial actions were taken. The managing general partner contracted with IBM Global Services to perform the assessment and remedial phases of its Year 2000 project. The managing general partner's total costs related to the Year 2000 problem were $2.5 million. 9 The managing general partner has closely monitored its information and non-information technology systems since the beginning of 2000 and has identified no significant Year 2000 failures or problems. The managing general partner will continue to monitor Year 2000 risks and issues. There can be no assurances that unforeseen problems will not be encountered in the future. 10 ITEM 8.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS December 31, 1999, 1998 and 1997 Note 1. Organization and nature of operations Parker & Parsley 90-C Conv., L.P. (the "Partnership") is a general partnership organized in 1990 under the laws of the State of Texas. The Partnership converted to a Delaware limited partnership on August 1, 1991. 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 in oil and gas development and production in 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: 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 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 estimated fair value of the asset. 18 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. 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 (loss) 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 includes 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. Allocated expenses are determined by the managing general partner based upon the level of activity of the Partnership relative to the non-partnership activities of the managing general partner. The method of allocation has been consistent over the past several years with certain modifications incorporated to reflect changes in Pioneer USA's overall business activities. Reclassifications - Certain reclassifications may have been made to the 1998 and 1997 financial statements to conform to the 1999 financial statement presentations. 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. No such liabilities have been accrued as of December 31, 1999. Revenue recognition - The Partnership uses the entitlements method of accounting for crude oil and natural gas revenues. Note 3. Impairment of long-lived assets In accordance with SFAS 121, the Partnership reviews its proved oil and gas properties for impairment whenever events and circumstances indicate a decline in the recoverability of the carrying value of the Partnership's oil and 19 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of December 31, 1999, 1998 and 1997, based on proved reserves, and compared such estimated future cash flows to the respective carrying amount of the oil and gas properties to determine if the carrying amounts were likely to be recoverable. For those proved 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, the Partnership recognized non-cash impairment provisions of $185,784 and $79,288 related to its proved oil and gas properties during 1998 and 1997, respectively. Note 4. Income taxes The financial statement basis of the Partnership's net assets and liabilities was $10,776 less than the tax basis at December 31, 1999. The following is a reconciliation of net income (loss) per statements of operations with the net income (loss) per Federal income tax returns for the years ended December 31: 1999 1998 1997 --------- ---------- --------- Net income (loss) per statements of operations $ 137,106 $ (258,625) $ 105,740 Depletion and depreciation provisions for tax reporting purposes (greater than) less than amounts for financial reporting purposes 76,676 50,997 (98,399) Impairment of oil and gas properties for financial reporting purposes - 185,784 79,288 Other, net (1,786) 1,870 (2,081) -------- --------- -------- Net income (loss) per Federal income tax returns $ 211,996 $ (19,974) $ 84,548 ======== ========= ======== Note 5. Oil and gas producing activities The following is a summary of the costs incurred, whether capitalized or expensed, related to the Partnership's oil and gas producing activities for the years ended December 31: 1999 1998 1997 ---------- ---------- ---------- Development costs $ 10,512 $ 13,347 $ 6,123 ========= ========= ========= Capitalized oil and gas properties consist of the following: 1999 1998 ----------- ----------- Proved properties: Property acquisition costs $ 226,701 $ 226,701 Completed wells and equipment 5,549,028 5,538,516 ---------- ---------- 5,775,729 5,765,217 Accumulated depletion (4,948,614) (4,861,804) ---------- ---------- Net capitalized costs $ 827,115 $ 903,413 ========== ========== 20 Note 6. Related party transactions Pursuant to the limited partnership agreement, the Partnership had the following related party transactions with the managing general partner or its affiliates during the years ended December 31: 1999 1998 1997 --------- --------- ---------- Payment of lease operating and supervision charges in accordance with standard industry operating agreements $ 126,701 $ 124,074 $ 128,942 Reimbursement of general and administrative expenses $ 16,060 $ 12,838 $ 17,703 The Partnership participates in oil and gas activities through an income tax partnership (the "Program") pursuant to the Program agreement. Pioneer USA, P&P Employees 90-C Conv., L.P. ("EMPL") (the "Entities"), Parker & Parsley 90-C, L.P. and the Partnership (the "Partnerships") are parties to the Program agreement. EMPL is a limited partnership organized for the benefit of certain employees of Pioneer USA. The costs and revenues of the Program are allocated to the Entities and the Partnerships as follows: Entities (1) Partnerships (2) ------------ ---------------- Revenues: Proceeds from disposition of depreciable and depletable properties - First three years 14.141414% 85.858586% After first three years 19.191919% 80.808081% All other revenues - First three years 14.141414% 85.858586% After first three years 19.191919% 80.808081% Costs and expenses: Lease acquisition costs, drilling and completion costs and all other costs 9.090909% 90.909091% Operating costs, reporting and legal expenses and general and administrative expenses- First three years 14.141414% 85.858586% After first three years 19.191919% 80.808081% (1) Excludes Pioneer USA's 1% general partner ownership which is allocated at the Partnership level and 30 limited partner interests owned by Pioneer USA. (2) The allocation between the Partnership and Parker & Parsley 90-C, L.P. is 38.349119% and 61.650881%, respectively. Note 7. Oil and gas information (unaudited) The following table represents information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1999, 1998 and 1997 and changes in such quantities during the years then ended. Due to a change in the accounting policy of the managing general partner in 1997, the Partnership began accounting for processed natural gas production in two components: processed natural gas liquids ("NGLs") and dry residue gas. NGLs are reflected in "Oil and NGLs" in the table below. All of the Partnership's reserves are proved developed 21 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 Williamson Petroleum Consultants, Inc., 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, 1997 451,860 1,139,784 Revisions 2,219 (662,760) Production (29,478) (50,304) ----------- ---------- Net proved reserves at December 31, 1997 424,601 426,720 Revisions (204,124) (171,338) Production (33,187) (30,348) ----------- ---------- Net proved reserves at December 31, 1998 187,290 225,034 Revisions 293,912 357,964 Production (32,618) (29,399) ----------- ---------- Net proved reserves at December 31, 1999 448,584 553,599 =========== ========== As of December 31, 1999, the estimated present value of future net revenues of proved reserves, calculated using December 31, 1999 prices of $25.36 per barrel of oil, $16.25 per barrel of NGLs and $1.75 per mcf of gas, discounted at 10% was approximately $2,484,000 and undiscounted was $4,695,000. 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. 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: 1999 1998 1997 -------- -------- -------- Plains All American Inc. 62% - - Genesis Crude Oil, L.P. - 69% 69% Western Gas Resources, Inc. 3% 13% 12% At December 31, 1999, the amount receivable from Plains All American Inc. was $36,890 which is included in the caption "Accounts receivable - oil and gas sales" in the accompanying Balance Sheet. 22 Pioneer USA is of the opinion that the loss of any one purchaser would not have an adverse effect on the ability of the Partnership to sell its oil and gas production or natural gas products. Note 9. Organization and operations The Partnership was organized December 28, 1990 as a general partnership under the Texas Uniform General Partnership Act for the purpose of acquiring and developing oil and gas properties. The Partnership converted to a Delaware limited partnership on August 1, 1991. The managing general partner received an opinion of legal counsel to the effect that such conversion will not result in material adverse tax consequences to the Partnership. 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. As managing general partner and operator of the Partnership's properties, all production expenses are incurred by Pioneer USA and billed to the Partnership and a portion of revenue is initially received by Pioneer USA prior to being paid to the Partnership. Under the 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 partners entered into subscription agreements for aggregate capital contributions of $7,531,000. 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.
