RECENT DEVELOPMENTS FOR PIONEER PARENT On October 31, 2001, Pioneer Parent announced an oil discovery on the Ozona Deep prospect in the deepwater Gulf of Mexico and the results from an appraisal well on the Stirrup discovery on the Gulf of Mexico shelf. The Ozona Deep discovery well was logged, fluid samples were taken for analysis, and the well will be temporarily suspended without further testing. Appraisal plans for 2002 will be finalized following the analysis of the data gathered in the discovery well. Pioneer Parent has a 32% working interest in the well and Marathon Oil Company has a 68% working interest and is operator. The Stirrup #2 appraisal well (Mustang Island block 861), the initial test of a second large fault block on the Stirrup structure, found three productive sequences in the middle Frio formation. The discovery well was temporarily suspended pending fabrication of facilities which is underway. First production is expected in April 2002. Pioneer Parent has a 25% working interest in the 5,600-acre unit that includes the Stirrup field. Pioneer Parent also announced that the well drilled on the Malta prospect on the Gulf of Mexico shelf encountered wet sands and will be plugged and abandoned. CAPITAL BUDGET AND FUTURE PRODUCTION OUTLOOK Pioneer Parent has adopted a $425 million capital expenditure budget for 2002, based upon current commodity prices. The 2002 capital expenditures budget includes $200 million of capital earmarked for development of Pioneer Parent's deepwater Gulf of Mexico Canyon Express, Devils Tower and Falcon projects and Pioneer Parent's Sable oil discovery offshore South Africa. Net to Pioneer Parent's interest, the aggregate production contributed by these projects is expected to increase Pioneer Parent's worldwide annual production by 12% during 2002, to a range of 46 to 48 million barrels of oil equivalent, or MMBOE, and by 31% in 2003, to a range of 60 to 63 MMBOE. THIRD QUARTER RESULTS FOR PIONEER PARENT Revenues from oil and gas operations were $198.1 million and $674.7 million for the three and nine months ended September 30, 2001, respectively, compared to $228.6 million and $600.9 million for the three and nine months ended September 30, 2000. The decrease in revenues during the three months ended September 30, 2001, as compared to the three months ended September 30, 2000, is due to commodity price decreases and a five percent decrease in production volumes. The increase in revenues for the nine months ended September 30, 2001, as compared to the nine months ended September 30, 2000, reflects commodity price increases which more than offset a four percent decrease in production volumes. -2- Average realized prices were $25.06 per barrel for oil, $15.01 per barrel for natural gas liquids and $2.66 per thousand cubic feet, or Mcf, for natural gas for the three months ended September 30, 2001, compared to average realized prices of $25.48, $20.73 and $2.87, respectively, for the three months ended September 30, 2000. Average realized prices were $24.95 per barrel for oil, $18.87 per barrel for natural gas liquids and $3.40 per Mcf for natural gas for the nine months ended September 30, 2001, compared to average realized prices of $23.52, $19.37 and $2.49, respectively, for the nine months ended September 30, 2000. Net income was $24.6 million, or $0.25 per share on a diluted basis, and $120.9 million, or $1.21 per share on a diluted basis, respectively, for the three and nine months ended September 30, 2001, compared to net income of $69.3 million, or $0.69 per share on a diluted basis, and $68.0 million, or $0.68 per share on a diluted basis, respectively, for the three and nine months ended September 30, 2000. Earnings for the three months ended September 30, 2001, as compared to the same period in 2000, decreased primarily as result of commodity price decreases. Earnings for the nine months ended September 30, 2001, as compared to the same period in 2000, increased primarily as a result of commodity price increases and an $8.7 million gain on the disposition of assets. During the nine months ended September 30, 2001, Pioneer Parent spent $364.4 million on capital expenditures including $170.2 million for development activities, $147.9 million for exploration activities and $46.3 million on acquisitions. While development activities include the costs of related facilities, exploration activities include geological and geophysical data purchases and acquisitions include the costs of leasing unproved properties, the majority of Pioneer Parent's capital expenditures is spent on drilling wells. Pioneer Parent has increased its 2001 capital expenditures budget by approximately 25% to $540 million from the $430 million budget originally established. This includes the recently announced acquisition of an incremental interest in the Aconcagua field and the Canyon Express gathering system and capital invested to appraise 2001 exploration discoveries. Pioneer Parent's total book capitalization at September 30, 2001 was $2.7 billion, consisting of total debt of $1.5 billion and stockholders' equity of $1.2 billion. Pioneer Parent reduced its total outstanding indebtedness by $17.7 million during the three months ended September 30, 2001 and by $24.2 million during the nine months ended September 30, 2001.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-A, L.P. (the "Partnership") is a limited partnership organized in 1988 under the laws of the State of Delaware. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's Report on Form 10-K for the year ended December 31, 2000, as filed with the Securities and Exchange Commission, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment 7 provision of $52,901 related to its proved oil and gas properties during the nine months ended September 30, 2001. NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $3,228,907 of which $3,153,865 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues increased 1% to $1,050,356 for the nine months ended September 30, 2001 as compared to $1,043,026 for the same period in 2000. The increase in revenues resulted from higher average prices received for gas, offset by lower average prices received for oil and natural gas liquids ("NGLs") and a decline in production. For the nine months ended September 30, 2001, 25,222 barrels of oil, 10,396 barrels of NGLs and 65,563 mcf of gas were sold, or 46,545 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 24,596 barrels of oil, 13,677 barrels of NGLs and 56,955 mcf of gas were sold, or 47,766 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 decreased $1.98, or 7%, from $28.30 for the nine months ended September 30, 2000 to $26.32 for the same period in 2001. The average price received per barrel of NGLs decreased $.25, or 2%, from $14.48 during the nine months ended September 30, 2000 to $14.23 for the same period in 2001. The average price received per mcf of gas increased 39% from $2.62 during the nine months ended September 30, 2000 to $3.64 for the same period in 2001. 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 during the nine months ended September 30, 2001. Gain on disposition of assets of $259 was recognized during the nine months ended September 30, 2000 resulting from equipment credits received on one well. 8 Costs and Expenses: Total costs and expenses increased to $625,145 for the nine months ended September 30, 2001 as compared to $526,077 for the same period in 2000, an increase of $99,068, or 19%. This increase was due to increases in the impairment of oil and gas properties, production costs, depletion and general and administrative expenses ("G&A"). Production costs were $439,961 for the nine months ended September 30, 2001 and $415,111 for the same period in 2000 resulting in an increase of $24,850, or 6%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by a decrease in workover costs. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A increased 1%, from $31,291 for the nine months ended September 30, 2000 to $31,511 for the same period in 2001, primarily due to a higher percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of increased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $52,901 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $100,772 for the nine months ended September 30, 2001 as compared to $79,675 for the same period in 2000, representing an increase of $21,097, or 26%. This increase was the result of a decrease in proved reserves during the period ended September 30, 2001 due to lower commodity prices and an increase in oil production of 626 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 31% to $279,405 for the three months ended September 30, 2001 as compared to $404,891 for the same period in 2000. The decrease in revenues resulted from lower average prices received and a decrease in production. For the three months 9 ended September 30, 2001, 7,667 barrels of oil, 3,981 barrels of NGLs and 17,597 mcf of gas were sold, or 14,581 BOEs. For the three months ended September 30, 2000, 9,541 barrels of oil, 4,325 barrels of NGLs and 20,466 mcf of gas were sold, or 17,277 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 decreased $1.83, or 7%, from $27.98 for the three months ended September 30, 2000 to $26.15 for the same period in 2001. The average price received per barrel of NGLs decreased $4.85, or 30%, from $15.92 during the three months ended September 30, 2000 to $11.07 for the same period in 2001. The average price received per mcf of gas decreased 41% from $3.38 during the three months ended September 30, 2000 to $1.98 for the same period in 2001. Costs and Expenses: Total costs and expenses increased to $243,469 for the three months ended September 30, 2001 as compared to $173,122 for the same period in 2000, an increase of $70,347, or 41%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by a decrease in G&A. Production costs were $146,434 for the three months ended September 30, 2001 and $130,098 for the same period in 2000, resulting in a $16,336 increase, or 13%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by a decline in production taxes. During this period, G&A decreased 31% from $12,147 for the three months ended September 30, 2000 to $8,383 for the same period in 2001, due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. The Partnership recognized a non-cash impairment provision of $52,901 related to its proved oil and gas properties during the period ended September 30, 2001. Depletion was $35,751 for the three months ended September 30, 2001 as compared to $30,877 for the same period in 2000, representing an increase of $4,874, or 16%. This increase was due to a decrease in proved reserves during the period ended September 30, 2001 compared to the same period in 2000 as a result of lower commodity prices, offset by a decrease in oil production of 1,874 barrels for the three months ended September 30, 2001 as compared to the same period in 2000. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $109,448 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to an increase in oil and gas sales receipts of $4,905 and a reduction of $129,613 in working capital, offset 10 by increases in production costs of $24,850 and G&A expenses of $220. The increase in revenue receipts resulted from increases in gas prices of $58,271 and $47,798 resulting from an increase in oil and gas production during 2001 as compared to the same period in 2000, offset by decreases of $54,476 in oil and NGL prices and $46,688 in NGL production. The increase in production costs was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by a decrease in workover costs. The increase in G&A was primarily due to a higher percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of increased oil and gas revenues. Net Cash Used in Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2001 and 2000 included expenditures related to equipment upgrades on various oil and gas properties. Proceeds from asset dispositions of $259 received during the nine months ended September 30, 2000 were due to equipment credits received on one well. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $538,398, of which $5,384 was distributed to the managing general partner and $533,014 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $594,086, of which $5,941 was distributed to the managing general partner and $588,145 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-A Conv., L.P. (the "Partnership") was organized in 1988 as a general partnership under the laws of the State of Texas and was converted to a Delaware limited partnership in 1989. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in these interim financial statements. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's report for the year ended December 31, 2000, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $15,533 related to its proved oil and gas properties during the nine months ended September 30, 2001. 6 NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $944,717 of which $922,941 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues increased 1% to $308,009 for the nine months ended September 30, 2001 as compared to $305,534 for the same period in 2000. The increase in revenues resulted from higher average prices received for gas, offset by lower average prices received for oil and natural gas liquids ("NGLs") and a decline in production. For the nine months ended September 30, 2001, 7,396 barrels of oil, 3,051 barrels of NGLs and 19,219 mcf of gas were sold, or 13,650 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 7,212 barrels of oil, 4,010 barrels of NGLs and 16,705 mcf of gas were sold, or 14,006 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 decreased $1.98, or 7%, from $28.30 for the nine months ended September 30, 2000 to $26.32 for the same period in 2001. The average price received per barrel of NGLs decreased $.25, or 2%, from $14.48 during the nine months ended September 30, 2000 to $14.23 for the same period in 2001. The average price received per mcf of gas increased 39% from $2.62 for the nine months ended September 30, 2000 to $3.64 for the same period in 2001. 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 during the nine months ended September 30, 2001. Gain on disposition of assets of $76 was recognized during the nine months ended September 30, 2000 resulting from equipment credits received on one fully depleted well. 7 Costs and Expenses: Total costs and expenses increased to $183,348 for the nine months ended September 30, 2001 as compared to $154,261 for the same period in 2000, an increase of $29,087, or 19%. This increase was due to increases in the impairment of oil and gas properties, production costs, depletion and general and administrative expenses ("G&A"). Production costs were $129,012 for the nine months ended September 30, 2001 and $121,722 for the same period in 2000, resulting in a $7,290 increase, or 6%. This increase was due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by lower workover costs. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A increased 1% from $9,166 for the nine months ended September 30, 2000 to $9,240 for the same period in 2001, primarily due to a higher percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of increased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $15,533 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $29,563 for the nine months ended September 30, 2001 as compared to $23,373 for the same period in 2000, an increase of $6,190, or 26%. This increase was due to a decrease in proved reserves during the period ended September 30, 2001 due to lower commodity prices for the nine months ended September 30, 2001 as compared to the same period in 2000 and an increase in oil production of 184 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. 8 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 31% to $81,958 for the three months ended September 30, 2001 as compared to $118,404 for the same period in 2000. The decrease in revenues resulted from lower average prices received and a decrease in production. For the three months ended September 30, 2001, 2,251 barrels of oil, 1,170 barrels of NGLs and 5,156 mcf of gas were sold, or 4,280 BOEs. For the three months ended September 30, 2000, 2,799 barrels of oil, 1,265 barrels of NGLs and 6,005 mcf of gas were sold, or 5,065 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 decreased $1.83, or 7%, from $27.98 for the three months ended September 30, 2000 to $26.15 for the same period in 2001. The average price received per barrel of NGLs decreased $4.85, or 30%, from $15.92 during the three months ended September 30, 2000 to $11.07 for the same period in 2001. The average price received per mcf of gas decreased 41% to $1.98 during the three months ended September 30, 2001 from $3.38 during the same period in 2000. Costs and Expenses: Total costs and expenses increased to $71,394 for the three months ended September 30, 2001 as compared to $50,753 for the same period in 2000, an increase of $20,641, or 41%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by a decline in G&A. Production costs were $42,940 for the three months ended September 30, 2001 and $38,155 for the same period in 2000 resulting in a $4,785 increase, or 13%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by lower production taxes. During this period, G&A decreased 31% from $3,552 for the three months ended September 30, 2000 to $2,458 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. The Partnership recognized a non-cash impairment provision of $15,533 related to its proved oil and gas properties during the three months ended September 30, 2001. Depletion was $10,463 for the three months ended September 30, 2001 as compared to $9,046 for the same period in 2000, an increase in depletion of $1,417, or 16%. This increase was attributable to a decrease in proved reserves during the period ended September 30, 2001 as a result of lower commodity prices, offset by a decrease in oil production of 548 barrels for the three months ended September 30, 2001 as compared to the same period in 2000. 9 LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $36,851 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to an increase in sales receipts of $1,783 and a reduction in working capital of $42,432, offset by increases in production costs of $7,290 and G&A expenses of $74. The increase in oil and gas receipts resulted from an increase of $17,129 in average prices received for gas and $358 resulted from the increase in production during 2001 as compared to the same period in 2000, offset by a decrease of $15,704 in average prices received for oil and NGLs during 2001. The increase in production costs was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by lower workover costs. The increase in G&A was primarily due to a higher percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of increased oil and gas revenues. Net Cash Used in Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2001 and 2000 were related to expenditures for equipment upgrades on various oil and gas properties. Proceeds of $76 recognized during the nine months ended September 30, 2000 were from equipment credits on one fully depleted well. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $157,877, of which $1,579 was distributed to the managing general partner and $156,298 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $174,206, of which $1,742 was distributed to the managing general partner and $172,464 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below. PROPOSAL TO ACQUIRE PARTNERSHIPS On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed definitive materials (the "proxy statement/prospectus") to solicit the approval of limited partners of 46 Parker & Parsley limited partnerships, including the Partnership, of an agreement and plan of merger among Pioneer, Pioneer USA, a wholly-owned subsidiary of Pioneer, and those limited partnerships.

The record date to identify the limited partners who are entitled to notice of and to vote at the special meetings was September 21, 2001. Each partnership that approves the 10 agreement and plan of merger and the other related merger proposals will merge with and into Pioneer USA. As a result, the partnership interests of those partnerships will be converted into the right to receive Pioneer common stock. The proxy statement/prospectus is non-binding and is subject to, among other things, consideration of offers from third parties to purchase any partnership or its assets and the majority approval of the limited partnership interests in each partnership.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley Producing Properties 88-A, L.P. (the "Partnership") is a limited partnership organized in 1988 under the laws of the State of Delaware. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's Report on Form 10-K for the year ended December 31, 2000, as filed with the Securities and Exchange Commission, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment 7 provision of $18,255 related to its proved oil and gas properties during the nine months ended September 30, 2001. NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $2,088,664 of which $2,053,405 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 4% to $510,321 for the nine months ended September 30, 2001 as compared to $529,705 for the same period in 2000. The decrease in revenues resulted from lower average prices received for oil and a decline in production, offset by higher average prices received for gas and natural gas liquids ("NGLs"). For the nine months ended September 30, 2001, 12,433 barrels of oil, 6,103 barrels of NGLs and 26,047 mcf of gas were sold, or 22,877 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 12,685 barrels of oil, 7,553 barrels of NGLs and 29,106 mcf of gas were sold, or 25,089 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 decreased $1.70, or 6%, from $28.54 for the nine months ended September 30, 2000 to $26.84 for the same period in 2001. The average price received per barrel of NGLs increased $.12, or 1%, from $13.80 during the nine months ended September 30, 2000 to $13.92 for the same period in 2001. The average price received per mcf of gas increased 61% from $2.18 during the nine months ended September 30, 2000 to $3.52 for the same period in 2001. 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 during the nine months ended September 30, 2001. 8 Gains on disposition of assets of $6,447 and $9,859 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The gain recognized during the nine months ended September 30, 2001 resulted from equipment credits received on one well that was plugged and abandoned during the current period. Expenses incurred during the nine months ended September 30, 2001 to plug this well were $10,766. The gain recognized during the period ended September 30, 2000 resulted from equipment credits received on one fully depleted well. Costs and Expenses: Total costs and expenses decreased to $299,646 for the nine months ended September 30, 2001 as compared to $329,745 for the same period in 2000, a decrease of $30,099, or 9%. This decrease resulted from decreases in production costs and general and administrative expenses ("G&A"), offset by increases in the impairment of oil and gas properties, abandoned property costs and depletion. Production costs were $199,948 for the nine months ended September 30, 2001 and $264,170 for the same period in 2000 resulting in a $64,222 decrease, or 24%. The decrease was primarily due to lower workover expenses and well maintenance costs, offset by higher ad valorem 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 9% from $15,891 for the nine months ended September 30, 2000 to $14,480 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of lower oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $18,255 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $56,197 for the nine months ended September 30, 2001 as compared to $49,684 for the same period in 2000, representing an increase of $6,513, or 13%. This increase was primarily the result of a downward revision in proved reserves during the period ended September 30, 2001 due to lower commodity prices as compared to the same period in 2000. 9 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 12% to $160,309 for the three months ended September 30, 2001 as compared to $182,810 for the same period in 2000. The decrease in revenues resulted from lower average prices received, offset by a slight increase in production. For the three months ended September 30, 2001, 4,175 barrels of oil, 2,263 barrels of NGLs and 9,878 mcf of gas were sold, or 8,084 BOEs. For the three months ended September 30, 2000, 4,197 barrels of oil, 2,315 barrels of NGLs and 8,704 mcf of gas were sold, or 7,963 BOEs. The average price received per barrel of oil decreased $4.06, or 13%, from $30.23 for the three months ended September 30, 2000 to $26.17 for the same period in 2001. The average price received per barrel of NGLs decreased $.38, or 3%, from $13.50 during the three months ended September 30, 2000 to $13.12 for the same period in 2001. The average price received per mcf of gas decreased 24% from $2.84 during the three months ended September 30, 2000 to $2.16 for the same period in 2001. Costs and Expenses: Total costs and expenses increased to $114,518 for the three months ended September 30, 2001 as compared to $90,138 for the same period in 2000, an increase of $24,380, or 27%. This increase was due to increases in the impairment of oil and gas properties and production costs, offset by declines in G&A and depletion. Production costs were $72,619 for the three months ended September 30, 2001 and $64,917 for the same period in 2000, resulting in a $7,702 increase, or 12%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by a decline in workover expenses. During this period, G&A decreased 28% from $5,484 for the three months ended September 30, 2000 to $3,974 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated as a result of lower oil and gas revenues. The Partnership recognized a non-cash impairment provision of $18,255 related to its proved oil and gas properties during the three months ended September 30, 2001. Depletion was $19,670 for the three months ended September 30, 2001 as compared to $19,737 for the same period in 2000, representing a decrease in depletion of $67. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $77,960 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to decreases in 10 production costs of $64,222 and G&A expenses of $1,411 and a reduction of $46,248 in working capital, offset by a decrease in oil and gas sales receipts of $23,155 and an increase in abandoned property costs of $10,766. The decrease in production costs was primarily due to lower workover expenses and well maintenance costs, offset by higher ad valorem taxes. The decrease in G&A was primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of lower oil and gas revenues. The decrease in oil and gas receipts resulted from the decline in oil prices of $21,616 during 2001 and $37,714 resulting from the decline in production during 2001 as compared to the same period in 2000, offset by an increase in gas and NGL prices of $36,175. Net Cash Provided by Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2000 were related to equipment upgrades on various oil and gas properties. Proceeds from disposition of assets of $6,447 and $9,859 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The proceeds recognized during the nine months ended September 30, 2001 resulted from equipment credits received on one well that was plugged and abandoned during the current period. The proceeds recognized during the period ended September 30, 2000 resulted from equipment credits received on one fully depleted well. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $271,879, of which $2,719 was distributed to the managing general partner and $269,160 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $339,285, of which $3,393 was distributed to the managing general partner and $335,892 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below. PROPOSAL TO ACQUIRE PARTNERSHIPS On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed definitive materials (the "proxy statement/prospectus") to solicit the approval of limited partners of 46 Parker & Parsley limited partnerships, including the Partnership, of an agreement and plan of merger among Pioneer, Pioneer USA, a wholly-owned subsidiary of Pioneer, and those limited partnerships.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-B, L.P. (the "Partnership") is a limited partnership organized in 1988 under the laws of the State of Delaware. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's Report on Form 10-K for the year ended December 31, 2000, as filed with the Securities and Exchange Commission, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment 7 provision of $34,975 related to its proved oil and gas properties during the nine months ended September 30, 2001. NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $3,086,337 of which $3,023,397 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 7% to $873,186 for the nine months ended September 30, 2001 as compared to $943,505 for the same period in 2000. The decrease in revenues resulted from lower average prices received for oil and a decline in production, offset by higher average prices received for gas and natural gas liquids ("NGLs"). For the nine months ended September 30, 2001, 22,346 barrels of oil, 7,311 barrels of NGLs and 32,649 mcf of gas were sold, or 35,099 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 24,263 barrels of oil, 10,130 barrels of NGLs and 41,502 mcf of gas were sold, or 41,310 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 decreased $.82, or 3%, from $28.32 for the nine months ended September 30, 2000 to $27.50 for the same period in 2001. The average price received per barrel of NGLs increased $.13, or 1%, from $15.11 during the nine months ended September 30, 2000 to $15.24 for the same period in 2001. The average price received per mcf of gas increased 81% from $2.49 during the nine months ended September 30, 2000 to $4.51 for the same period in 2001. 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 during the nine months ended September 30, 2001. Gain on disposition of assets of $7,855 was recognized during the nine months ended September 30, 2001 due to the sale of equipment on one well plugged and abandoned during the current period. A gain of $15,953 was recognized during the same period in 2000 resulting from an $11,638 salvage 8 income from one well plugged and abandoned during the current period and $4,315 from equipment credits received on one fully depleted well. Abandoned property costs of $10,528 and $8,226 were incurred during the nine months ended September 30, 2001 and 2000, respectively, to abandon these wells. Costs and Expenses: Total costs and expenses increased to $501,790 for the nine months ended September 30, 2001 as compared to $407,518 for the same period in 2000, an increase of $94,272, or 23%. This increase was due to increases in production costs, depletion, the impairment of oil and gas properties and abandoned property costs, offset by a decline in general and administrative expenses ("G&A"). Production costs were $366,524 for the nine months ended September 30, 2001 and $319,196 for the same period in 2000, resulting in an increase of $47,328, or 15%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs and workover expenses incurred to stimulate well production. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A decreased 22% from $28,305 for the nine months ended September 30, 2000 to $21,943 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $34,975 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $68,090 for the nine months ended September 30, 2001 as compared to $51,791 for the same period in 2000, representing an increase of $16,299, or 31%. This increase was the result of a reduction in proved reserves during the period ended September 30, 2001 as a result of lower commodity prices as compared to the same period in 2000, offset by a decline in oil production of 1,917 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. 9 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 26% to $259,220 for the three months ended September 30, 2001 as compared to $352,159 for the same period in 2000. The decrease in revenues resulted from lower average prices received and a decline in production. For the three months ended September 30, 2001, 7,949 barrels of oil, 2,619 barrels of NGLs and 11,857 mcf of gas were sold, or 12,544 BOEs. For the three months ended September 30, 2000, 7,752 barrels of oil, 3,707 barrels of NGLs and 14,807 mcf of gas were sold, or 13,927 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 decreased $5.15, or 16%, from $31.31 for the three months ended September 30, 2000 to $26.16 for the same period in 2001. The average price received per barrel of NGLs decreased $5.65, or 33%, from $16.90 during the three months ended September 30, 2000 to $11.25 for the same period in 2001. The average price received per mcf of gas decreased 42% from $3.16 during the three months ended September 30, 2000 to $1.84 for the same period in 2001. Gain on disposition of assets of $7,108 was recognized during the three months ended September 30, 2000. The gain was comprised of $4,315 from equipment credits received on one fully depleted well and $2,793 received from salvage income on one well plugged and abandoned during the current period. Abandoned property costs of $17 and $8,226 were incurred during the three months ended September 30, 2001 and 2000, respectively, resulting from one well plugged and abandoned during the current periods. Costs and Expenses: Total costs and expenses increased to $206,416 for the three months ended September 30, 2001 as compared to $149,208 for the same period in 2000, an increase of $57,208, or 38%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by decreases in abandoned property costs and G&A. Production costs were $133,495 for the three months ended September 30, 2001 and $114,143 for the same period in 2000 resulting in a $19,352 increase, or 17%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production, offset by lower production and ad valorem taxes. During this period, G&A decreased 38% from $10,565 for the three months ended September 30, 2000 to $6,594 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. 10 The Partnership recognized a non-cash impairment provision of $34,975 related to its proved oil and gas properties during the three months ended September 30, 2001. Depletion was $31,335 for the three months ended September 30, 2001 as compared to $16,274 for the same period in 2000, representing an increase of $15,061, or 93%. This increase was due to a decrease in proved reserves during the period ended September 30, 2001 as a result of lower commodity prices as compared to the same period in 2000. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $16,140 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to reductions of $131,429 in working capital and G&A expenses of $6,362, offset by increases in production costs of $47,328, abandoned property costs of $2,032 and a reduction in oil and gas sales receipts of $72,291. The decrease in oil and gas receipts resulted from the decline of $21,833 in oil prices during 2001 and $135,612 resulting from the decline in production during 2001 as compared to the same period in 2000, offset by increases in gas and NGL prices of $85,154. The increase in production costs was primarily due to higher ad valorem taxes and additional well maintenance and workover costs incurred to stimulate well production. The decrease in G&A was primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. Net Cash Provided by Investing Activities The Partnership's investing activities during the nine months ended September 30, 2001 and 2000 were related to upgrades of oil and gas equipment on various oil and gas properties. Proceeds from dispositions of assets of $6,471 was recognized during the nine months ended September 30, 2001. The proceeds were comprised of $5,968 received from the sale of equipment on one well plugged and abandoned during the current period and $503 from equipment credits received on one active well. Proceeds of $13,102 received during the same period in 2000 were due to $8,845 on one well plugged and abandoned during the current period and $4,257 from equipment credits on one fully depleted well. Net Cash Used in Financing Activities For the nine months ended September 30, 2000, cash distributions to the partners were $429,915, of which $4,299 was distributed to the managing general partner and $425,616 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $556,511, of which $5,565 was distributed to the managing general partner and $550,946 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into 11 Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-B Conv., L.P. (the "Partnership") was organized in 1988 as a general partnership under the laws of the State of Texas and was converted to a Delaware limited partnership in 1989. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in these interim financial statements. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's report for the year ended December 31, 2000, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $14,234 related to its proved oil and gas properties during the nine months ended September 30, 2001. 6 NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $1,252,584 of which $1,233,237 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Revenues: Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 The Partnership's oil and gas revenues decreased 7% to $354,526 for the nine months ended September 30, 2001 as compared to $383,160 for the same period in 2000. The decrease in revenues resulted from lower average prices received for oil and a decline in production, offset by higher average prices received for gas and natural gas liquids ("NGLs"). For the nine months ended September 30, 2001, 9,074 barrels of oil, 2,963 barrels of NGLs and 13,253 mcf of gas were sold, or 14,246 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 9,855 barrels of oil, 4,114 barrels of NGLs and 16,862 mcf of gas were sold, or 16,779 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 decreased $.82, or 3%, from $28.32 for the nine months ended September 30, 2000 to $27.50 for the same period in 2001. The average price received per barrel of NGLs increased $.13, or 1%, from $15.11 during the nine months ended September 30, 2000 to $15.24 for the same period in 2001. The average price received per mcf of gas increased 81% from $2.49 during the nine months ended September 30, 2000 to $4.51 in 2001. 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 during the nine months ended September 30, 2001. Gain on disposition of assets of $3,190 was recognized during the nine months ended September 30, 2001 due to the sale of equipment on one well plugged and abandoned during the current period. A gain of $6,478 was recognized during the same period in 2000 resulting from a $4,726 salvage income from one well plugged and abandoned during the current period and $1,752 from equipment credits received on one fully depleted well. Abandoned property costs of $4,165 and $3,340 were 7 incurred during the nine months ended September 30, 2001 and 2000, respectively, to abandon these wells. Costs and Expenses: Total costs and expenses increased to $203,746 for the nine months ended September 30, 2001 as compared to $165,492 for the same period in 2000, an increase of $38,254, or 23%. This increase was due to increases in production costs, the impairment of oil and gas properties, depletion and abandoned property costs, offset by a decline in general and administrative expenses ("G&A"). Production costs were $148,819 for the nine months ended September 30, 2001 and $129,611 for the same period in 2000, resulting in a $19,208 increase, or 15%. The increase was due to higher ad valorem taxes and additional well maintenance and workover costs incurred to stimulate well production. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A decreased 22% from $11,495 for the nine months ended September 30, 2000 to $8,909 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $14,234 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $27,619 for the nine months ended September 30, 2001 as compared to $21,046 for the same period in 2000, an increase of $6,573, or 31%. This increase was due to a decrease in proved reserves during the period ended September 30, 2001 due to lower commodity prices as compared to the same period in 2000, offset by a decrease in oil production of 781 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. 8 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 26% to $105,325 for the three months ended September 30, 2001 as compared to $143,104 for the same period in 2000. The decrease in revenues resulted from lower average prices received and a decrease in production. For the three months ended September 30, 2001, 3,234 barrels of oil, 1,060 barrels of NGLs and 4,816 mcf of gas were sold, or 5,097 BOEs. For the three months ended September 30, 2000, 3,152 barrels of oil, 1,508 barrels of NGLs and 6,019 mcf of gas were sold, or 5,663 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 decreased $5.15, or 16%, from $31.31 for the three months ended September 30, 2000 to $26.16 for the same period in 2001. The average price received per barrel of NGLs decreased $5.65, or 33%, from $16.90 during the three months ended September 30, 2000 to $11.25 for the same period in 2001. The average price received per mcf of gas decreased 42% to $1.84 during the three months ended September 30, 2001 from $3.16 during the same period in 2000. Gain on disposition of assets of $2,886 was recognized during the three months ended September 30, 2000. The gain was comprised of $1,752 from equipment credits received on one fully depleted well and $1,134 received from salvage income on one well plugged and abandoned during the current period. Abandoned property costs of $6 and $3,340 were incurred during the three months ended September 30, 2001 and 2000, respectively, resulting from one well plugged and abandoned during the current periods. Costs and Expenses: Total costs and expenses increased to $83,848 for the three months ended September 30, 2001 as compared to $60,614 for the same period in 2000, an increase of $23,234, or 38%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by declines in abandoned property costs and G&A. Production costs were $54,225 for the three months ended September 30, 2001 and $46,350 for the same period in 2000, resulting in a $7,875 increase, or 17%. The increase was due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production. During this period, G&A decreased 38% from $4,293 for the three months ended September 30, 2000 to $2,679 for the same period in 2001 primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. The Partnership recognized a non-cash impairment provision of $14,234 related to its proved oil and gas properties during the three months ended September 30, 2001. 9 Depletion was $12,704 for the three months ended September 30, 2001 as compared to $6,631 for the same period in 2000, an increase of $6,073, or 92%. This increase was attributable to a decrease in proved reserves during the period ended September 30, 2001 as a result of lower commodity prices as compared to the same period in 2000. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $14,656 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to reductions of $61,524 in working capital and $2,586 in G&A expenses, offset by increases in production costs of $19,208 and abandoned property costs of $825 and a reduction in oil and gas sales receipts of $29,421. The decrease in oil and gas receipts resulted from the decrease of $8,833 in oil prices and $55,318 resulting from the decline in production during 2001 as compared to the same period in 2000, offset by an increase of $34,730 in gas and NGL prices. The increase in production costs was primarily due to higher ad valorem taxes and additional well maintenance and workover costs incurred to stimulate well production. The decrease in G&A was due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. Net Cash Provided by Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2001 and 2000 were related to expenditures for equipment upgrades on various oil and gas properties. Proceeds from disposition of assets of $2,628 was recognized during the nine months ended September 30, 2001. The gain was comprised of $2,424 received from the sale of equipment on one well plugged and abandoned during the current period and $204 from equipment credits received on one active well. Proceeds of $5,320 received during the same period in 2000 were due to $3,591 on one well plugged and abandoned during the current period and $1,729 from equipment credits on one fully depleted well. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $174,578, of which $1,746 was distributed to the managing general partner and $172,832 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $225,984, of which $2,260 was distributed to the managing general partner and $223,724 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below. 10 PROPOSAL TO ACQUIRE PARTNERSHIPS On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed definitive materials (the "proxy statement/prospectus") to solicit the approval of limited partners of 46 Parker & Parsley limited partnerships, including the Partnership, of an agreement and plan of merger among Pioneer, Pioneer USA, a wholly-owned subsidiary of Pioneer, and those limited partnerships.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-C, L.P. (the "Partnership") is a limited partnership organized in 1988 under the laws of the State of Delaware. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in these interim financial statements. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's report for the year ended December 31, 2000, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment 6 provision of $7,965 related to its proved oil and gas properties during the nine months ended September 30, 2001. NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $714,658 of which $706,056 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 5% to $215,744 for the nine months ended September 30, 2001 as compared to $227,002 for the same period in 2000. The decrease in revenues resulted from lower average prices received for oil and a decline in production, offset by higher average prices received for gas and natural gas liquids ("NGLs"). For the nine months ended September 30, 2001, 5,252 barrels of oil, 2,090 barrels of NGLs and 8,970 mcf of gas were sold, or 8,837 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 5,698 barrels of oil, 2,609 barrels of NGLs and 10,687 mcf of gas were sold, or 10,088 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 decreased $.73, or 3%, from $28.38 for the nine months ended September 30, 2000 to $27.65 for the same period in 2001. The average price received per barrel of NGLs increased $.19, or 1%, from $15.03 during the nine months ended September 30, 2000 to $15.22 for the same period in 2001. The average price received per mcf of gas increased 77% from $2.44 during the nine months ended September 30, 2000 to $4.31 for the same period in 2001. 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 during the nine months ended September 30, 2001. Gains on disposition of assets of $1,788 and $3,630 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The gain recognized during the period ended September 7 30, 2001 was due to salvage income received on one well plugged and abandoned during the current period. The gain recognized during the period ended September 30, 2000 was primarily due to salvage income received on one well plugged and abandoned during the period ended 2000. Costs and Expenses: Total costs and expenses increased to $127,356 for the nine months ended September 30, 2001 as compared to $102,546 for the same period in 2000, an increase of $24,810, or 24%. This increase was due to increases in production costs, the impairment of oil and gas properties, depletion and abandoned property costs, offset by a decline in general and administrative expenses ("G&A"). Production costs were $92,793 for the nine months ended September 30, 2001 and $80,121 for the same period in 2000 resulting in a $12,672 increase, or 16%. The increase was primarily due to additional well maintenance and workover costs incurred to stimulate well production and higher ad valorem 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 2%, from $6,810 for the nine months ended September 30, 2000 to $6,703 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $7,965 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $17,558 for the nine months ended September 30, 2001 as compared to $13,743 for the same period in 2000, an increase of $3,815, or 28%. This increase was due to a reduction in proved reserves during the period ended September 30, 2001 due to lower commodity prices, offset by a decline in oil production of 446 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. Abandoned property costs of $2,337 and $1,872 were incurred for the nine months ended September 30, 2001 and 2000, respectively, to plug and abandon one well during the current periods. 8 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 27% to $62,636 for the three months ended September 30, 2001 as compared to $85,503 for the same period in 2000. The decrease in revenues resulted from a decline in production and lower average prices received. For the three months ended September 30, 2001, 1,849 barrels of oil, 701 barrels of NGLs and 3,159 mcf of gas were sold, or 3,077 BOEs. For the three months ended September 30, 2000, 1,884 barrels of oil, 903 barrels of NGLs and 3,601 mcf of gas were sold, or 3,387 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 decreased $4.98, or 16%, from $31.26 for the three months ended September 30, 2000 to $26.28 for the same period in 2001. The average price received per barrel of NGLs decreased $5.53, or 32%, from $17.08 during the three months ended September 30, 2000 to $11.55 for the same period in 2001. The average price received per mcf of gas decreased 40% to $1.88 during the three months ended September 30, 2001 from $3.11 during the same period in 2000. A gain on disposition of assets of $1,617 recognized during the three months ended September 30, 2000 was due to salvage income received on one well plugged and abandoned during the period ended 2000. Costs and Expenses: Total costs and expenses increased to $51,630 for the three months ended September 30, 2001 as compared to $36,744 for the same period in 2000, an increase of $14,886, or 41%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by declines in G&A and abandoned property costs. Production costs were $33,832 for the three months ended September 30, 2001 and $27,815 for the same period in 2000, resulting in a $6,017 increase, or 22%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production. During this period, G&A decreased 24%, from $2,565 for the three months ended September 30, 2000 to $1,950 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. The Partnership recognized a non-cash impairment provision of $7,965 related to its proved oil and gas properties during the three months ended September 30, 2001. 9 Depletion was $7,876 for the three months ended September 30, 2001 as compared to $4,492 for the same period in 2000, an increase of $3,384, or 75%. This increase was attributable to a reduction in proved reserves during the period ended September 30, 2001 due to lower commodity prices. Abandoned property costs of $7 and $1,872 were incurred for the three months ended September 30, 2001 and 2000, respectively, to plug and abandon one well during the current periods. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $11,272 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to reductions in working capital of $35,957 and G&A expenses of $107, offset by increases in production costs of $12,672 and abandoned property costs of $465 and a decline in oil and gas receipts of $11,655. The decrease in oil and gas receipts resulted from a decline in oil commodity prices of $4,158 during 2001 and a decline in production during 2001 of $27,641, offset by an increase in gas and NGL commodity prices of $20,144. The increase in production costs was primarily due to additional well maintenance and workover costs incurred to stimulate well production and higher ad valorem taxes. The decrease in G&A was primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. Net Cash Provided by Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2001 and 2000 included expenditures related to equipment upgrades on various oil and gas properties. Proceeds from asset dispositions of $1,472 and $2,981 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The proceeds recognized during 2001 were primarily due to salvage income received on a well plugged and abandoned during the current year. The proceeds recognized during 2000 were due to salvage income received on one well plugged and abandoned during the period ended 2000. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $103,549, of which $1,035 was distributed to the managing general partner and $102,514 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $133,968, of which $1,340 was distributed to the managing general partner and $132,628 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA"). For further information, see "Proposal to acquire partnerships" below. 10 PROPOSAL TO ACQUIRE PARTNERSHIPS On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed definitive materials (the "proxy statement/prospectus") to solicit the approval of limited partners of 46 Parker & Parsley limited partnerships, including the Partnership, of an agreement and plan of merger among Pioneer, Pioneer USA, a wholly-owned subsidiary of Pioneer, and those limited partnerships.

(A Delaware Limited Partnership) NOTES TO FINANCIAL STATEMENTS September 30, 2001 (Unaudited) NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS Parker & Parsley 88-C Conv., L.P. (the "Partnership") was organized in 1988 as a general partnership under the laws of the State of Texas and was converted to a Delaware limited partnership in 1989. 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. BASIS OF PRESENTATION In the opinion of management, the unaudited financial statements of the Partnership as of September 30, 2001 and for the three and nine months ended September 30, 2001 and 2000 include all adjustments and accruals consisting only of normal recurring accrual adjustments which are necessary for a fair presentation of the results for the interim period. These interim results are not necessarily indicative of results for a full year. Certain reclassifications may have been made to the September 30, 2000 financial statements to conform to the September 30, 2001 financial statement presentations. Certain information and footnote disclosure normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted in these interim financial statements. The financial statements should be read in conjunction with the financial statements and the notes thereto contained in the Partnership's report for the year ended December 31, 2000, a copy of which is available upon request by writing to Rich Dealy, Vice President and Chief Accounting Officer, 5205 North O'Connor Boulevard, Suite 1400, Irving, Texas 75039-3746. NOTE 3. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $11,171 related to its proved oil and gas properties during the nine months ended September 30, 2001. 6 NOTE 4. PROPOSAL TO ACQUIRE PARTNERSHIP On October 22, 2001, Pioneer Natural Resources Company ("Pioneer") mailed materials to the limited partners of the Partnership soliciting their approval of an agreement and plan of merger among Pioneer, Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of Pioneer, and the Partnership. Pioneer has valued the Partnership interest at $1,009,229 of which $996,208 is attributable to the limited partners, excluding Pioneer USA in its capacity as a general partner or a limited partner. If a majority of the limited partners approve the transaction, each limited partner will receive their proportionate share of the value in the form of Pioneer common stock. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (1) RESULTS OF OPERATIONS Nine months ended September 30, 2001 compared with nine months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 5% to $302,836 for the nine months ended September 30, 2001 as compared to $318,657 for the same period in 2000. The decrease in revenues resulted from lower average prices received from oil and a decline in production, offset by higher average prices received for gas and natural gas liquids ("NGLs"). For the nine months ended September 30, 2001, 7,375 barrels of oil, 2,938 barrels of NGLs and 12,521 mcf of gas were sold, or 12,400 barrel of oil equivalents ("BOEs"). For the nine months ended September 30, 2000, 7,994 barrels of oil, 3,665 barrels of NGLs and 14,995 mcf of gas were sold, or 14,158 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 decreased $.73, or 3%, from $28.38 for the nine months ended September 30, 2000 to $27.65 for the same period in 2001. The average price received per barrel of NGLs increased $.19, or 1%, from $15.03 during the nine months ended September 30, 2000 to $15.22 for the same period in 2001. The average price received per mcf of gas increased 77% from $2.44 during the nine months ended September 30, 2000 to $4.31 for the same period in 2001. 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 during the nine months ended September 30, 2001. Gains on disposition of assets of $2,508 and $5,093 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The gain recognized during the period ended September 30, 2001 was due to salvage income received on one well plugged and abandoned during the current period. The gain recognized during the period ended September 30, 2000 was primarily due to salvage income received on one well plugged and abandoned during the period ended 2000. 7 Costs and Expenses: Total costs and expenses increased to $178,487 for the nine months ended September 30, 2001 as compared to $143,949 for the same period in 2000, an increase of $34,538, or 24%. The increase was due to increases in production costs, the impairment of oil and gas properties, depletion and abandoned property costs, offset by a decline in general and administrative expenses ("G&A"). Production costs were $130,202 for the nine months ended September 30, 2001 and $112,471 for the same period in 2000 resulting in a $17,731 increase, or 16%. The increase was primarily due to additional well maintenance and workover costs incurred to stimulate well production and higher ad valorem taxes. G&A's components are independent accounting and engineering fees and managing general partner personnel costs. During this period, G&A decreased 5%, from $9,560 for the nine months ended September 30, 2000 to $9,129 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. 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 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 gas properties. The Partnership has estimated the expected future cash flows of its oil and gas properties as of September 30, 2001, 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 a non-cash impairment provision of $11,171 related to its proved oil and gas properties during the nine months ended September 30, 2001. Depletion was $24,706 for the nine months ended September 30, 2001 as compared to $19,292 for the same period in 2000, an increase of $5,414, or 28%. This increase was due to a reduction in proved reserves during the period ended September 30, 2001 due to lower commodity prices, offset by a decline in oil production of 619 barrels for the nine months ended September 30, 2001 as compared to the same period in 2000. Abandoned property costs of $3,279 and $2,626 were incurred for the nine months ended September 30, 2001 and 2000, respectively, to plug and abandon one well during the current periods. 8 Three months ended September 30, 2001 compared with three months ended September 30, 2000 Revenues: The Partnership's oil and gas revenues decreased 27% to $87,732 for the three months ended September 30, 2001 as compared to $119,902 for the same period in 2000. The decrease in revenues resulted from a decline in production and lower average prices received. For the three months ended September 30, 2001, 2,598 barrels of oil, 980 barrels of NGLs and 4,361 mcf of gas were sold, or 4,305 BOEs. For the three months ended September 30, 2000, 2,639 barrels of oil, 1,267 barrels of NGLs and 5,043 mcf of gas were sold, or 4,747 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 decreased $4.98, or 16%, from $31.26 for the three months ended September 30, 2000 to $26.28 for the same period in 2001. The average price received per barrel of NGLs decreased $5.53, or 32%, from $17.08 during the three months ended September 30, 2000 to $11.55 for the same period in 2001. The average price received per mcf of gas decreased 40% to $1.88 during the three months ended September 30, 2001 from $3.11 during the same period in 2000. A gain on disposition of assets of $2,269 recognized during the three months ended September 30, 2000 was due to salvage income received on one well plugged and abandoned during the period ended 2000. Costs and Expenses: Total costs and expenses increased to $72,132 for the three months ended September 30, 2001 as compared to $51,613 for the same period in 2000, an increase of $20,519, or 40%. This increase was due to increases in the impairment of oil and gas properties, production costs and depletion, offset by declines in G&A and abandoned property costs. Production costs were $47,414 for the three months ended September 30, 2001 and $39,073 for the same period in 2000, resulting in an $8,341 increase, or 21%. The increase was primarily due to higher ad valorem taxes and additional well maintenance costs incurred to stimulate well production. During this period, G&A decreased 32%, from $3,597 for the three months ended September 30, 2000 to $2,451 for the same period in 2001, primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. The Partnership recognized a non-cash impairment provision of $11,171 related to its proved oil and gas properties during the three months ended September 30, 2001. Depletion was $11,047 for the three months ended September 30, 2001 as compared to $6,317 for the same period in 2000, an increase of $4,730, or 75%. This increase was attributable to a reduction in proved reserves during the period ended September 30, 2001 due to lower commodity prices. 9 Abandoned property costs of $49 and $2,626 were incurred for the three months ended September 30, 2001 and 2000, respectively, to plug and abandon one well during the current periods. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities increased $15,842 during the nine months ended September 30, 2001 from the same period ended September 30, 2000. This increase was due to reductions in working capital of $50,213 and G&A expenses of $431, offset by increases in production costs of $17,731 and abandoned property costs of $653 and a reduction in oil and gas receipts of $16,418. The decrease in oil and gas receipts resulted from the decrease in oil commodity prices during 2001 of $5,974 and a decline in production of $38,893 during 2001 as compared to the same period in 2000, offset by increased gas and NGL commodity prices of $28,449. The increase in production costs was primarily due to additional well maintenance and workover costs incurred to stimulate well production and higher ad valorem taxes. The decrease in G&A was primarily due to a lower percentage of the managing general partner's G&A being allocated (limited to 3% of oil and gas revenues) as a result of decreased oil and gas revenues. Net Cash Provided by Investing Activities The Partnership's principal investing activities during the nine months ended September 30, 2001 and 2000 included expenditures related to equipment upgrades on various oil and gas properties. Proceeds from asset dispositions of $2,066 and $4,183 were recognized during the nine months ended September 30, 2001 and 2000, respectively. The proceeds recognized during 2001 were primarily due to salvage income received on a well plugged and abandoned during the current year. The proceeds recognized during 2000 were due to salvage income received on one well plugged and abandoned during the period ended 2000. Net Cash Used in Financing Activities For the nine months ended September 30, 2001, cash distributions to the partners were $145,293, of which $1,453 was distributed to the managing general partner and $143,840 to the limited partners. For the same period ended September 30, 2000, cash distributions to the partners were $187,973, of which $1,880 was distributed to the managing general partner and $186,093 to the limited partners. During 2001, the Partnership made distributions in March and July but no distributions were made by the Partnership during September pending the vote of the proposed merger of the Partnership into Pioneer Natural Resources USA, Inc. ("Pioneer USA").
