Parker & Parsley Petroleum Company and other predecessors of Pioneer Natural Resources USA, Inc., a Delaware corporation, sponsored the partnerships. Pioneer USA is a direct 100% owned subsidiary of Pioneer Natural Resources Company, a Delaware corporation, and is the managing or sole general partner of the partnerships. The purpose of these special meetings is for you to consider and vote on the following matters: 1. A proposal to approve an Agreement and Plan of Merger dated as of , 1999, among Pioneer, Pioneer USA, and each of the partnerships. Each partnership that approves this proposal will merge with and into Pioneer USA, with Pioneer USA surviving the merger. Each partnership interest of a participating partnership, other than Pioneer USA's interests, will be converted into the right to receive an amount of cash. The amount of cash to be paid for all partnership interests of a participating partnership will be based on the participating partnership's merger value. The merger value of a participating partnership is equal to the sum of its reserve value and its net working capital, as reduced by its pro rata share of the estimated expenses and fees of the mergers of all of the partnerships, in each case as of September 30, 1999. Each partnership's pro rata share of the estimated expenses and fees is based on its reserve value before any reduction for the estimated expenses and fees. WE CALCULATED THE CASH PAYMENT USING INFORMATION AS OF JUNE 30, 1999 FOR PURPOSES OF ILLUSTRATION. WE INTEND TO CHANGE EACH REFERENCE TO "JUNE 30, 1999" TO BE "SEPTEMBER 30, 1999" AND TO REVISE JUNE 30, 1999 NUMBERS AS OF SEPTEMBER 30, 1999 BEFORE MAILING THE DEFINITIVE PROXY STATEMENT TO THE LIMITED PARTNERS. The cash payment will be allocated among the 3 partners based on the liquidation provisions of each partnership agreement. Pioneer USA will not receive any cash payment for its partnership interests in the participating partnerships. However, as a 4 result of the mergers, Pioneer USA will acquire 100% of the properties of the participating partnerships, including properties attributable to its partnership interests in those partnerships. 2. A proposal to amend the partnership agreement of each partnership to permit the partnership's merger with Pioneer USA. If the amendment is not approved, that partnership cannot merge into Pioneer USA even if the partners of that partnership approve the merger agreement. 3. A proposal to approve the opinion issued to Pioneer USA by on behalf of the limited partners that neither the grant nor the exercise of the right to approve the mergers by the limited partners will result in the loss of any limited partner's limited liability or adversely affect the tax status of the partnerships and to approve the selection of as special legal counsel for the limited partners to render such legal opinion. 4. Other business that properly comes before the special meetings or any adjournments or postponements of the special meetings. We are not aware of any other business for the special meetings. The accompanying proxy statement contains information about the mergers, including the amount of cash to be paid per $1,000 initial investment in each partnership, and descriptions of the merger agreement, the merger amendment and the legal opinion of the special legal counsel for the limited partners. The proxy statement also contains a copy of the merger agreement, the merger amendment and the legal opinion. Pioneer USA's board of directors set the close of business on , 1999, as the record date to identify the limited partners who are entitled to notice of, and to vote at, the special meetings or any adjournments or postponements of the special meetings. During the ten days before the special meetings, you may examine lists of the limited partners of your partnership at the offices of Pioneer USA during normal business hours for any purpose relevant to the special meetings. ON , 1999, PIONEER USA'S BOARD OF DIRECTORS UNANIMOUSLY DETERMINED THAT THE MERGERS ARE ADVISABLE, FAIR TO YOU, AND IN YOUR BEST INTERESTS. THE BOARD RECOMMENDS THAT YOU VOTE FOR THE MERGER AGREEMENT, THE MERGER AMENDMENT, THE SELECTION OF SPECIAL LEGAL COUNSEL FOR THE LIMITED PARTNERS AND THAT COUNSEL'S LEGAL OPINION. ALTHOUGH PIONEER USA'S BOARD OF DIRECTORS HAS ATTEMPTED TO FULFILL ITS FIDUCIARY DUTIES TO YOU, PIONEER USA'S BOARD OF DIRECTORS HAD CONFLICTING INTERESTS IN EVALUATING THE MERGERS BECAUSE EACH MEMBER OF ITS BOARD OF DIRECTORS IS ALSO AN OFFICER OF PIONEER. Each partnership requires the favorable vote of the holders of the majority of its limited partnership interests to approve the merger agreement, the merger amendment, the selection of special legal counsel for the limited partners and that counsel's legal opinion. IF YOU DO NOT SEND IN YOUR PROXY CARD OR VOTE AT THE SPECIAL MEETINGS, IT WILL HAVE THE SAME EFFECT AS IF YOU VOTED AGAINST THE MERGERS. You are requested to sign, vote and date the enclosed proxy card and return it promptly in the enclosed envelope, even if you expect to be present at the special meetings. If you give a proxy, you can revoke it at any time before the special meetings. If you are present at the special meetings, you may withdraw your proxy and vote in person. By Order of the Board of Directors, Mark L. Withrow Executive Vice President, General Counsel and Secretary , 1999 5 PRELIMINARY PROXY STATEMENT, SUBJECT TO COMPLETION [LOGO] PIONEER NATURAL RESOURCES USA, INC. 1400 WILLIAMS SQUARE WEST 5205 NORTH O'CONNOR BLVD. IRVING, TEXAS 75039 , 1999 Dear Limited Partners: We invite you to attend the special meetings of limited partners of the partnerships described below. The special meetings will be held on , 1999, at 2:00 p.m., at the Wyndham Anatole Hotel, Room, 2201 Stemmons Freeway, Dallas, Texas 75207. The purpose of the special meetings is for you to vote on mergers of the partnerships that, if completed, will result in your receiving cash for your partnership interests. Pioneer Natural Resources Company, a Delaware corporation, desires to acquire 25 publicly-held limited partnerships. We are a direct 100% owned subsidiary of Pioneer and we are the managing or sole general partner of the partnerships. Our predecessors, including Parker & Parsley Petroleum Company, originally sponsored the partnerships. The partnerships are Texas and Delaware limited partnerships. They were formed from 1982 through 1991 to acquire, develop and produce oil and gas reserves. If you and the other limited partners approve the mergers, the partnerships will be merged with and into us and we will survive the mergers. We have retained Robert A. Stanger & Co., Inc. to issue a fairness opinion in connection with the mergers. Robert A. Stanger & Co., Inc.'s opinion is dated as of , 1999 and, subject to the qualifications stated in such opinion, states that the merger values to be paid in cash for the limited partner interests are fair from a financial point of view to the limited partners of the partnerships. The written opinion of Robert A. Stanger & Co., Inc. is contained in the accompanying document. You should read all of it carefully. We can complete the mergers only if a majority of the limited partners approve the merger agreement, the amendment to the partnership agreements to permit the mergers, the selection of special legal counsel for the limited partners and that counsel's legal opinion for their partnerships. This document provides information about the proposed mergers. It also includes a copy of the merger agreement, the merger amendment and the legal opinion of the special legal counsel for the limited partners. Please give all of this information your careful attention. YOUR VOTE IS IMPORTANT. Whether or not you plan to attend the special meetings, please take the time to vote by completing and mailing to us the enclosed proxy card. This will not prevent you from revoking your proxy at any time prior to the special meetings or from voting your partnership interests in person if you later choose to attend the special meetings. We intend to mail checks to the partners of participating partnerships promptly after completing the mergers. Certificates representing partnership interests will be automatically cancelled, and you will not have to surrender your certificates to receive the cash payment. Sincerely, Mark L. Withrow Executive Vice President, General Counsel and Secretary YOU SHOULD CAREFULLY CONSIDER THE RISKS RELATING TO THE MERGERS DESCRIBED IN "RISK FACTORS."

PIONEER AND PIONEER USA DETERMINED THE MERGER VALUES AND WILL NOT ADJUST THEM FOR CHANGES IN PARTNERSHIP VALUES BEFORE THE MERGERS ARE COMPLETED. - YOU WERE NOT INDEPENDENTLY REPRESENTED IN ESTABLISHING THE TERMS OF THE MERGERS. - OUR BOARD OF DIRECTORS HAD CONFLICTING INTERESTS IN EVALUATING THE MERGERS BECAUSE EACH MEMBER OF OUR BOARD OF DIRECTORS IS ALSO AN OFFICER OF PIONEER. THE TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE FAIRNESS OR MERITS OF THE TRANSACTION NOR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS DOCUMENT.

THE SUPPLEMENT CONSTITUTES AN INTEGRAL PART OF THIS DOCUMENT FOR THAT PARTNERSHIP. PLEASE CAREFULLY READ ALL OF THE SUPPLEMENTS FOR THE PARTNERSHIPS IN WHICH YOU ARE A LIMITED PARTNER. ii 8 SUMMARY This summary highlights some information from this document and may not contain all of the information that is important to you. To understand the mergers and to obtain a more detailed description of the legal terms of the mergers, you should carefully read this entire document, the related partnership supplements, and the documents described in "Where You Can Find More Information" on page 52. For definitions of oil and gas terms used in this document, see "Commonly Used Oil and Gas Terms" on page . When we use the terms "Pioneer USA," "we," "us" or "our," we are referring to Pioneer Natural Resources USA, Inc. including its consolidated subsidiaries and predecessors, unless the context otherwise requires. When we use the term "Pioneer," we are referring to Pioneer Natural Resources Company. When we use the term "merger proposals," we are referring to the proposals to approve the merger agreement, the merger amendment, the selection of special legal counsel for the limited partners and the legal opinion of that counsel. THE MERGERS Pioneer proposes to acquire the partnerships by merging them into us. We will be the survivor of each merger. The partnership interests of each participating partnership, other than our interests, will be converted into the right to receive cash. The amount of cash Pioneer will pay for a partnership interest will be based on the merger value of the partnership and the liquidation provisions of the partnership agreement. Pioneer and Pioneer USA determined the merger values primarily based on the present value of estimated future net revenues from the partnerships' oil and gas reserves at June 30, 1999. In determining the present value, Pioneer and Pioneer USA used (1) an arithmetic average of the five-year New York Mercantile Exchange, or NYMEX, futures price as of June 30, 1999 for oil, which was approximately $18.00 per barrel, or Bbl, of oil, less standard industry adjustments, (2) the NYMEX price of $2.40 per thousand cubic feet, or Mcf, of gas, less standard industry adjustments, and (3) a 12.5% discount rate. In addition, each participating partnership's merger value includes its net working capital as of June 30, 1999, as reduced by its pro rata share of the estimated expenses and fees of the mergers of all of the partnerships. The partnership's pro rata share of the estimated expenses and fees is based on its reserve value before any reduction for the estimated expenses and fees. On page 3 of this document is a table that shows important information about the partnerships, including the amount of cash that will be paid in the mergers for each $1,000 of initial investment. For purposes of illustration in this preliminary document, we calculated the merger values using information as of June 30, 1999. We intend to revise those numbers as of September 30, 1999 before mailing this document to the limited partners. Pioneer and Pioneer USA agreed to structure the transaction as mergers instead of as property sales followed by liquidation of the partnerships because the mergers will: - require fewer legal documents; - reduce filing fees and other costs; and - result in the same amount of cash to the limited partners as would a property sale and liquidation using the same commodity prices. Pioneer and Pioneer USA expect to sign the merger agreement as soon as the September 30, 1999 merger values are determined. However, if the oil and gas commodity prices used in calculating the merger values for this preliminary document materially increase or decrease after the date of determination for this preliminary document and before mailing this document to the limited partners, Pioneer or Pioneer USA might abandon the proposed mergers before submitting the merger proposals to the limited partners for approval. THE COMPANIES PIONEER NATURAL RESOURCES COMPANY 1400 Williams Square West 5205 North O'Connor Blvd. Irving, Texas 75039 (972) 444-9001 Pioneer is an independent exploration and production company. Its common stock is traded 9 on the New York Stock Exchange and the Toronto Stock Exchange under the symbol "PXD." Pioneer files annual, quarterly and special reports, proxy statements and other information with the Securities and Exchange Commission. Those SEC filings are available to you in the same manner as the partnerships' information. See "Where You Can Find More Information" on page 52 of this document. PIONEER NATURAL RESOURCES USA, INC. 1400 Williams Square West 5205 North O'Connor Blvd. Irving, Texas 75039 (972) 444-9001 We prepared this document to solicit your proxy. We are a 100% owned subsidiary of Pioneer. We directly own almost all of Pioneer's United States oil and gas properties. THE PARTNERSHIPS c/o Pioneer Natural Resources USA, Inc. 1400 Williams Square West 5205 North O'Connor Blvd. Irving, Texas 75039 (972) 444-9001 The names of the partnerships are found in the table on the next page. All of the partnerships produce and sell oil and gas. The partnerships were generally formed to provide the general and limited partners cash flow from operations and, in some cases, tax incentives. See the supplement to this document for each of your partnerships for specific information about your partnerships, including the merger value as a multiple of distributions for the 12 months ended June 30, 1999. As a result of the partnerships' oil and gas operations, the partnerships distribute cash to the limited and general partners from the partnerships' net cash flows. These distributions are made quarterly, unless sufficient cash is not available. The partnerships' properties consist of interests in approximately 1,100 oil and gas wells that are located primarily in the Spraberry field of the Permian Basin of West Texas. We operate most of the partnerships' wells. At December 31, 1998, the partnerships' combined total proved reserves were 12.2 million barrels of oil equivalent, or MMBOE, consisting of 9.6 million barrels, or MMBbls, of oil and natural gas liquids and 15.6 billion cubic feet, or Bcf, of natural gas. Approximately 94% of the reserves are attributable to the limited partners' partnership interests, excluding partnership interests owned directly by us. Approximately 79% of the total proved reserves attributable to the properties are oil and liquids, and 21% are natural gas, based on six Mcf of gas being equivalent to one Bbl of oil. See "The Partnerships" on page 50 of this document for more information about the partnerships. 2 10 SUMMARY TABLE -- MERGER VALUE AND AMOUNT OF INITIAL LIMITED PARTNER INVESTMENT REPAID This table contains the following summary information for each partnership: - the aggregate merger values assigned to: -- Pioneer USA's partnership interests, whether general or limited; -- its nonmanaging general partners' partnership interests, excluding Pioneer USA; -- its limited partners, excluding Pioneer USA; and - for each $1,000 initial limited partner investment in that partnership: -- the merger value; -- the total historical cash distributions through June 30, 1999; and -- the total amount of initial investment by the limited partners that has been repaid, after giving effect to the mergers, stated in dollars and as a percentage. This information is based on assumptions. You should read the following table together with the detailed information in Table 2 and Table 3 of Appendix A to this document. To provide an example in this preliminary document, we prepared the following table of merger values using information as of June 30, 1999. We intend to revise those numbers as of September 30, 1999 prior to mailing the definitive document to the limited partners. Interests in some partnerships were sold in units at prices other than $1,000. We have presented this information based on a $1,000 initial investment for ease of use and comparison among partnerships. You should not assume that the amount shown per $1,000 investment is the same as any value or amount attributable to a single unit investment.

The mergers provide liquidity to the limited partners at a price based on oil and gas reserve values, not on limited market demand for illiquid partnership interests. All limited partners in participating partnerships will receive cash payments in exchange for their partnership interests shortly after completion of the mergers. The cash payments will include both the partnership's reserve value and its net working capital less the partnership's share of transaction expenses. None of the partnership interests are traded on a national stock exchange or in any other significant market. No liquid market exists for interests in any of the partnerships. See Table 14 of Appendix A for historical information about recent trades of partnership interests in the partnerships. Repurchase obligations exist in only a few of the partnerships and are limited in both amount and price by formula in the partnership agreements. Although some partnership interests are occasionally sold in private or over-the-counter transactions, we believe the potential buyers in such transactions are few and the prices generally reflect a significant discount for illiquidity. Liquidation Value. The merger values are based on the value of the underlying properties, which are essentially the same values that could be achieved by selling the partnerships' property interests and liquidating the partnerships at this time. In addition, we believe that the lump sum cash payment to each limited partner in the mergers is higher than what the limited partners would otherwise receive over the life of the partnership, assuming constant oil and gas commodity prices and operating costs and giving effect to the time value of money, for the following reasons: - The partnership agreements require cash distributions to be reduced by general and administrative expenses allocable to each partnership. The merger values reflect liquidation values based on reserve values that have not been reduced for general and administrative expenses. - The merger values are based upon current oil and gas prices. It is likely that oil and gas prices will vary often and possibly widely, as has been demonstrated historically, from the prices used to prepare these estimates. In that way, the merger values eliminate the potential loss in value due to lower oil and gas prices. Acceleration of Realization of Value. The cash payments to limited partners of participating partnerships will provide those limited partners with cash earlier than if the limited partners remain in the partnership and receive the expected ordinary cash distributions from oil and gas production. Because the partnerships' properties are mature producing properties, we believe that production from those properties will continue to decline at the rate predicted in the partnerships' oil and gas engineering reserve reports. Accordingly, cash distributions from the partnerships are also expected to decline, subject to variation for changes in oil and gas prices. We believe the merger value of each partnership represents an appropriate pricing of estimated future distributions from the partnership because: - the merger value of each partnership is based primarily on the partnership's oil and gas reserves which have been evaluated using (1) an arithmetic average of the five-year NYMEX futures price as of June 30, 1999 for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments; and - the 12.5% discount rate appropriately reflects, among other things, the potential volatility of future oil and gas commodity prices given historical trends. Elimination of Partnership Tax Reports. The mergers will eliminate the limited partners' Schedule K-1 tax reports in the participating partnerships for tax years after the mergers occur. This is expected to simplify the limited partners' individual tax return preparation and reduce preparation costs. 4 12 RECOMMENDATION TO LIMITED PARTNERS (SEE PAGE 15) On , 1999, our board of directors unanimously determined that the mergers are advisable, fair to you, and in your best interests. Our board recommends that you vote for the merger proposals. Although our board of directors has attempted to fulfill its fiduciary duties to you, our board of directors had conflicting interests in evaluating the mergers because each member of our board of directors is also an officer of Pioneer. FAIRNESS In deciding to approve the mergers on , 1999, our board of directors decided that the mergers are advisable, fair to you, and in your best interests based on a variety of factors. These factors include: - the form and amount of consideration offered to the partners; - the comparison of the cash payments in the mergers to the diminished future cash distributions otherwise expected as oil and gas production continues to decline; - the elimination after the mergers of limited partners' tax preparation costs relating to partnership tax information; - that Pioneer is offering a competitive price because of: -- the commodity pricing used in determining the merger values; -- Pioneer USA's position as operator of most of the partnerships' wells; and -- Pioneer USA's significant ownership of nearby properties; and - the fairness opinion from Robert A. Stanger & Co., Inc. FAIRNESS OPINION OF FINANCIAL ADVISOR (SEE PAGE 16) Robert A. Stanger & Co., Inc., has issued a fairness opinion dated , 1999, expressing its opinion that, subject to the qualifications expressed in the opinion, the merger values to be paid in cash for the limited partner interests are fair from a financial point of view to the limited partners of the partnerships. The full text of the form of written opinion of Robert A. Stanger & Co., Inc. is attached to this document as Appendix C. You should read all of it carefully. THE OPINION OF ROBERT A. STANGER & CO., INC. IS DIRECTED TO OUR BOARD OF DIRECTORS. IT IS NOT A RECOMMENDATION TO YOU ABOUT HOW YOU SHOULD VOTE ON MATTERS RELATING TO THE PROPOSED MERGERS. MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 28) You will generally recognize gain or loss equal to the difference between the cash proceeds you receive in the mergers and your adjusted tax basis in your partnership interests in the participating partnerships for which the cash proceeds are paid. Your gain or loss will be capital or ordinary depending on the nature of the assets held by the participating partnerships in which you hold interests and the amount of depletion and intangible drilling and development costs that must be recaptured. You must calculate your ordinary and capital gain or loss separately for each partnership in which you have interests. TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGERS TO YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD SEEK TAX ADVICE FOR A FULL UNDERSTANDING OF THE PARTICULAR TAX CONSEQUENCES OF THE MERGERS TO YOU. RECORD DATE; VOTING POWER You may vote at the special meetings if you owned partnership interests as of the close of business on , 1999. We call this date the record date. For each partnership in which you own a partnership interest, you may cast one vote representing your percentage of partnership interests in that partnership. The percentage of partnership interests that you own is determined by comparing the amount of: - your, or your predecessor's, initial investment, including any additional assessments, in the partnership; to - the total investment of all partners, including any additional assessments, in the partnership. 5 13 PARTNER VOTE REQUIRED TO APPROVE THE MERGERS The favorable vote of a majority of the limited partners' partnership interests in a partnership is required to approve the merger proposals for that partnership. We are generally entitled to vote partnership interests we hold as limited partners at the special meetings. See "The Special Meetings -- Record Date; Voting Rights and Proxies" on page 40 of this document. We plan to vote all our partnership interests for the merger proposals. The voting interest that we hold in each partnership is found in Table 6 of Appendix A. If limited partners of a partnership approve the merger agreement, but do not approve the merger amendment, or vice versa, the partnership will not be able to merge. LIMITED PARTNERS WHO WANT THEIR PARTNERSHIP TO PARTICIPATE IN THE MERGERS SHOULD VOTE FOR EACH OF THE MERGER PROPOSALS. CONDITIONS TO THE MERGERS (SEE PAGE 36) We will complete the mergers only if the conditions of the merger agreement are satisfied or, if permitted, waived. These conditions include: - the limited partners' adoption and approval of the merger proposals; - the absence of any law or court order that prohibits the mergers; and - the absence of any lawsuit challenging the legality or any aspect of the mergers. So long as the law allows us to do so, Pioneer and we may choose to complete the mergers even though a condition has not been satisfied if the limited partners have approved the merger proposals. Pioneer and we may complete the merger of any one or some of the partnerships, even if limited partners in other partnerships do not approve the mergers. TERMINATION OF THE MERGERS (SEE PAGE 37) Pioneer and Pioneer USA may jointly terminate the merger agreement, for any or all of the partnerships, at any time, even after limited partner approval. Pioneer USA will not consent to any termination unless it believes such termination is in the best interests of the partnerships. Either Pioneer or Pioneer USA may terminate the merger agreement, for any or all of the partnerships, in certain circumstances, including the following: - the limited partners of a partnership fail to approve that partnership's merger; or - if any of the other parties is in material breach of the merger agreement. In addition, Pioneer USA may terminate the merger agreement for any partnership, if Pioneer USA determines that termination of the merger agreement is required for its board of directors to comply with its fiduciary duties. EFFECTS OF MERGERS ON LIMITED PARTNERS WHO DO NOT VOTE IN FAVOR OF THE MERGERS You will be bound by the mergers if the limited partners in your partnerships vote a majority of their partnership interests in favor of the mergers, even if you vote against the mergers. If the merger of your partnership occurs, you will be entitled to receive only an amount of cash based on the merger value of your partnership interests. You will not have appraisal, dissenters' or similar rights in connection with the mergers, even if you vote against the mergers. FUTURE OF PARTNERSHIPS THAT DO NOT PARTICIPATE IN THE MERGERS (SEE PAGE 31) If your partnership does not participate in the mergers for any reason, that partnership will remain in existence. Some reasons your partnership might not participate in the mergers are (1) that the limited partners vote against the merger, (2) that a condition in the merger agreement is not satisfied, or (3) that Pioneer or we exercise a termination right with respect to the merger for that partnership. At the same time that we mail checks to the partners of participating partnerships in payment 6 14 of the merger values, we will mail any cash distributions that were delayed for administrative purposes prior to the completion of the mergers to the partners of nonparticipating partnerships. We have not formulated an alternative business plan for nonparticipating partnerships. The business objectives of each nonparticipating partnership will continue as they are. We plan to continue to manage each nonparticipating partnership and operate it in accordance with the terms of its current partnership agreement. The partnership will continue to operate as a separate legal entity with its own assets and liabilities. Distributions from these partnerships are expected to continue to decline since their production revenues are expected to continue to decline more quickly than their production costs. Regardless of whether these nonparticipating partnerships distribute cash, limited partners must continue to include their share of partnership income and loss in their individual tax returns. The board of directors of each of Pioneer and Pioneer USA will decide what, if any, actions Pioneer or Pioneer USA, respectively, will take regarding these partnerships. Potential activities might include a tender offer for partnership interests of limited partners or a proposal to acquire the assets of, or merge with, one or more of the nonparticipating partnerships. The proposal may be on terms similar to or different from those of the mergers described in this document. EXPENSES AND FEES The expenses and fees that we will incur in connection with the mergers are expected to be approximately $4.6 million. Each of the partnerships, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Similar Transactions" below, which participates in the mergers, will pay its pro rata share of the estimated expenses and fees of the mergers allocated to all of the partnerships. The net working capital component of each partnership's merger value has been reduced by that partnership's pro rata share of the estimated expenses and fees. The partnership's pro rata share is based on its reserve value before any reduction for the estimated expenses and fees. SIMILAR TRANSACTIONS (SEE PAGE 45) At the same time as this transaction, Pioneer is also offering to acquire 21 non-public limited partnerships and 13 privately-held employee partnerships through mergers of those partnerships into Pioneer USA. The terms of the mergers and the method of establishing merger values for limited partners in those partnerships are the same as those for the 25 publicly-held partnerships in this document. As of the record date for the special meetings, Scott D. Sheffield, Chairman of the Board, President and Chief Executive Officer of Pioneer and President of Pioneer USA, owned, on average, approximately 6% of the outstanding limited partnership interests in each of 11 of the 13 privately-held employee partnerships. As of the record date for the special meetings, Mark L. Withrow, Executive Vice President, General Counsel and Secretary of each of Pioneer and Pioneer USA, owned, on average, approximately 5% of the outstanding limited partnership interests in each of two of the 13 privately-held employee partnerships. Mr. Sheffield and Mr. Withrow have advised us that they plan to vote their partnership interests for the merger proposals. THIRD-PARTY OFFERS (SEE PAGE 32) We will consider any offers from third parties to purchase any partnership, whether one of the publicly-held partnerships discussed in this document or one of the non-public or employee partnerships, or the assets of any partnership. Those who wish to make an offer for any partnership or its assets must demonstrate to our reasonable satisfaction their financial ability and willingness to complete such a transaction. Before reviewing non-public information about a partnership, a third party will need to enter into a customary confidentiality agreement. We will also disclose the price at which Pioneer will acquire the non-public and employee partnerships. Offers should be at prices and on terms that are fair to the partners of the partnership and more favorable to the limited partners than the prices and terms proposed in the mergers. Pioneer has the right to try to match or top any such offer. 7 15 RISK FACTORS YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS IN DETERMINING WHETHER TO VOTE TO APPROVE THE MERGER PROPOSALS. THE MERGER VALUES INVOLVE ESTIMATES THAT WILL NOT BE ADJUSTED Estimates of Proved Reserves and Future Net Revenues May Change. The calculations of the partnerships' proved reserves of crude oil, natural gas liquids and natural gas and future net revenues from those reserves included in this document are only estimates. The accuracy of any reserve estimate is a function of: - the quality of available data; - engineering and geological interpretation and judgment; - the assumptions about quantities of recoverable oil, natural gas liquids and natural gas reserves; - the assumptions about prices for crude oil, natural gas liquids and natural gas; and - the assumptions about costs to extract, transport and process, if necessary, crude oil, natural gas liquids and natural gas to their point of sale. Actual prices, production, operating expenses and quantities of recoverable oil and natural gas reserves may vary from those assumed in the estimates. The variances may be significant. Any significant variance from the assumptions used could result in the actual quantity of the partnerships' reserves and future net revenues being materially different from the estimates in the partnerships' reserve reports and in the calculation of the merger values. In addition, changes in production levels and changes in crude oil, natural gas liquids and natural gas prices after the date of the estimate may result in substantial upward or downward revisions. Assumptions about Reserves, Pricing and Costs Used in the Merger Values May Be Wrong. Pioneer and Pioneer USA based the reserve value component of the merger values on the discounted, or present value of, estimated future net revenues from the partnerships' properties using estimated reserves at June 30, 1999, - applying (1) an arithmetic average of the five-year NYMEX futures price as of June 30, 1999 for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments, and - using a 12.5% discount rate. Pioneer and Pioneer USA calculated the volumes of the partnership's proved reserves as of June 30, 1999, based on a future production curve consistent with the production curve used in the reserve report of Williamson Petroleum Consultants, Inc. as of December 31, 1998. Actual production may vary from that assumed production. Actual prices in the future may be materially higher or lower than those used in the calculation of the merger values, even though Pioneer and Pioneer USA adjusted the estimated future net revenues for standard industry price adjustments, including: - production costs; - the effects of oil quality; - British thermal unit, or BTU, content for gas; - oil and gas gathering and transportation costs; and - gas processing costs and shrinkage. 8 16 Therefore, the estimated future net revenues may differ materially from actual revenues received in the future. In addition, actual future net revenues will be affected by: - the timing of production and related expenses; - changes in consumption; and - changes in governmental regulations or taxation. The 12.5% discount rate used in the calculation of the merger values might not reflect actual interest rates in effect from time to time and risks associated with the partnerships' properties or the oil and gas industry in general. The discount rate may disfavor longer-lived properties when compared to shorter-lived properties, with a resulting effect on the merger values that disfavors some partnerships as compared to others. The Merger Values Might Not Reflect the Value of the Partnerships' Assets. Since the merger value assigned to a partnership is based on assumptions about reserves, pricing and costs, that merger value could vary materially from the current market value of, or the price that a third party might offer for, that partnership's estimated oil and gas reserves and from the value of, or given to, that partnership's actual future net revenues. The assumptions used to determine the merger values may ultimately benefit some partners and partnerships as opposed to others because the merger value of a partnership might not properly reflect the value of that partnership's assets. In that case, some partners could receive less than a fair market price for their partnership interests. For a description of other methods of determining merger values, see "Method of Determining Merger Values and Amount of Cash Offered -- Other Methods of Determining Merger Values" on page 24. The Merger Values Will Not Be Adjusted For Changes Before the Completion of the Mergers. The merger values determine the amount of cash you will receive in the mergers. The merger values will be determined when the September 30, 1999 data is available and will not be changed. For example, although oil and gas prices have fluctuated greatly in the recent past and may continue to do so, the merger values will not be adjusted as of the closing date of the mergers to reflect any general changes in oil or gas prices, or any other matter generally affecting the oil and gas industry, occurring after September 30, 1999 and prior to the closing date of the mergers. YOU WERE NOT INDEPENDENTLY REPRESENTED IN ESTABLISHING THE TERMS OF THE MERGERS Pioneer and Pioneer USA determined the terms of the mergers, including the method for determining the merger values, and the type and allocation among the partners of the consideration to be given in exchange for partnership interests. As noted below, our board of directors had conflicting interests in evaluating the mergers primarily because each member of that board of directors is also an officer of Pioneer. We did not seek recommendations about the type of transaction or the terms or prices from any independent underwriter, financial advisor or other securities professional prior to accepting the consideration offered by Pioneer. The only independent representatives in the mergers were Sayles & Lidji, A Professional Corporation, which represented Pioneer USA's board of directors, and Robert A. Stanger & Co., Inc., which will render its fairness opinion to Pioneer USA's board of directors. Moreover, no special committee or other entity was formed or engaged to negotiate on our behalf or the partnerships' behalf. No representative group of limited partners and no outside experts or consultants, such as investment bankers, legal counsel, accountants or financial experts, were engaged solely to represent the independent interests of the limited partners in structuring and negotiating the terms of the mergers. If you had been separately represented, the terms of the mergers might have been different and possibly more favorable to you. In addition, if you were separately represented, issues unique to the value of your partnerships might have received greater attention during the structuring of the mergers, which might have resulted in an increase in the merger value assigned to your partnerships and in the amount of cash paid to you in the mergers. 9 17 THE INTERESTS OF PIONEER, PIONEER USA AND THEIR DIRECTORS AND OFFICERS MAY DIFFER FROM YOUR INTERESTS The interests of Pioneer, Pioneer USA, and their officers and directors may differ from your interests as a result of the relationships among them. For example, Pioneer USA, as general partner of the partnerships, has a duty to manage the partnerships in the best interests of the limited partners. Additionally, Pioneer USA has a duty to operate its business for the benefit of its sole stockholder, Pioneer. Also, the members of Pioneer USA's board of directors have duties to both the limited partners of the partnerships and to Pioneer. All of the members of Pioneer USA's board of directors are officers of Pioneer and have duties to Pioneer's stockholders. Pioneer USA's board of directors was aware of these interests and considered them in approving the merger proposals. See "Interests of Pioneer, Pioneer USA and Their Directors and Officers" beginning on page 43 of this document. PIONEER USA HAS NOT PREVIOUSLY OFFERED THE PARTNERSHIPS FOR SALE TO OTHERS Although the partnerships have sold individual properties from time to time in the ordinary course of their businesses, we have not previously tried to sell any of the partnerships, as a whole, to third parties. As a result, we cannot be sure what the market demand is for the partnerships' properties, as a whole, or what a third party would offer for any partnership. PIONEER USA DID NOT SOLICIT ANY THIRD-PARTY OFFERS We have not solicited offers for the partnerships or their assets, and no assurance may be given that the terms of the mergers are as favorable as could be obtained from a sale of any such partnerships or assets to an unrelated party. We will consider offers to purchase any partnership or its assets from third parties, but there might not be any third-party offers or, to the extent an offer is made, we might not consider that offer to be a viable alternative to the mergers. THIRD PARTIES MIGHT NOT MAKE AN OFFER FOR THE PARTNERSHIPS IF THEY CANNOT BECOME OPERATOR OF THE PARTNERSHIPS' PROPERTIES We operate most of the partnerships' wells on behalf of the partnerships and others who own interests in those wells, including Pioneer. Although we will consider other offers for the partnerships or their assets, we are not offering to sell the rights to operate the partnerships' properties. Consequently, potential buyers may not be interested in making an offer to acquire any of the partnerships if they cannot also acquire operating rights to the partnerships' properties. POTENTIAL LITIGATION CHALLENGING THE MERGERS MAY DELAY OR BLOCK THE MERGERS One or more of the partners opposed to the mergers may initiate legal action to stop the mergers or to seek damages for alleged violations of federal and state laws. Litigation challenging the mergers may delay or block the closing of the mergers. In addition, if any lawsuits are filed, Pioneer or Pioneer USA may decide to terminate the mergers. REPURCHASE RIGHTS TERMINATE ON COMPLETION OF THE MERGERS The limited partners of each of the partnerships listed below may require us to repurchase their partnership interests for cash at the times and under the conditions described in the partnership agreements: Parker & Parsley 82-I, Ltd. Parker & Parsley 82-II, Ltd. Parker & Parsley 83-A, Ltd. Parker & Parsley 83-B, Ltd. Parker & Parsley 84-A, Ltd. 10 18 If the limited partners of a partnership with repurchase rights vote a majority of their partnership interests in favor of the mergers, those repurchase rights will terminate on completion of the mergers. The repurchase rights may be exercised only once a year and the amount of partnership interests required to be purchased in any one year is limited. A repurchase price is calculated by multiplying: - the present value of the estimated future net revenues, calculated using a discount rate equal to prime plus 1% as of December 31 of each year, from a partnership's proved reserves, as determined by independent petroleum consultants; by - 66 2/3%. Generally, the repurchase prices would be less than the merger values because of the additional discount factor equal to 33 1/3% for the repurchases. In calculating the 1999 repurchase prices, Pioneer USA decided not to apply that additional 33 1/3% discount factor because oil and gas prices had increased significantly since December 31, 1998. The merger values are higher than the 1999 repurchase prices. The difference between the 1999 repurchase prices and the merger values is attributable primarily to the use of different oil and gas prices and discount rates. The repurchase prices were calculated using NYMEX oil and gas prices as of December 31, 1998, which were $12.00 per Bbl of oil and $2.00 per Mcf of gas, compared to the merger values which were calculated using (1) an arithmetic average of the five-year NYMEX futures price as of June 30, 1999 for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments. The higher oil and gas prices used in the merger values more than offset the use in the calculation of the repurchase prices of a discount rate equal to prime plus 1%, or 8.75% for the 1999 repurchases, which was lower than the 12.5% discount rate used in calculating the merger values. The 1999 repurchase offers were commenced and completed before the date of this document. For a list of the repurchase prices in 1999 and the prior two years, see Table 8 of Appendix A. SPECIAL FACTORS BACKGROUND OF THE MERGERS The partnerships were formed from 1982 through 1991 under the sponsorship of various affiliated companies collectively known as Parker & Parsley. On February 19, 1991, Parker & Parsley's principal company converted from limited partnership form to corporate form and acquired most of the assets of five publicly-held oil and gas limited partnerships. The new corporation was called Parker & Parsley Petroleum Company, and it owned the general partners of the partnerships. In early 1992, Parker & Parsley Petroleum Company decided that it could not fully realize the benefits of the properties it had acquired while continuing to devote substantial resources to the sponsorship of and drilling for the partnerships. It stopped sponsoring public and private oil and gas development drilling and income partnerships and focused on its corporate development. In 1997, Parker & Parsley Petroleum Company and MESA Inc. combined their businesses in a merger that created Pioneer Natural Resources Company. That same year, Pioneer combined many of its U.S. subsidiaries, including the general partners of the partnerships, into its main subsidiary, Pioneer USA. From time to time since 1992, Pioneer and its predecessors have had general, internal discussions about whether to consolidate the partnerships pursuant to a transaction such as the mergers. On several occasions, Pioneer or its predecessors engaged outside legal counsel and had discussions with investment banks about a possible combination of the partnerships. Some of those discussions were with Robert A. Stanger & Co., Inc. The contemplated structure of the combination has varied significantly during these internal discussions and has included issuances of common stock, combinations of common stock and cash, and cash-only transactions through asset sales, mergers, tender offers, and combinations of those types of transactions. In general, the contemplated transactions would have been taxable to the limited partners because of the difficulties involved in structuring a tax-free transaction for the partnerships. Until now, 11 19 every time Pioneer or its predecessors considered such a transaction, it decided not to propose any transaction to the limited partners. The reasons Pioneer and its predecessors did not previously propose a transaction to the limited partners varied. In some early cases, they wanted to collect and fully distribute proceeds to the limited partners from litigation against an oilfield services company before trying to value the partnerships. In other cases, they wanted to avoid periods of volatility in oil and gas prices or in Pioneer's stock price. On several occasions, Pioneer was involved in other corporate transactions that could not be completed timely if a transaction with the partnerships was also pending. In early 1998, Pioneer was formulating a strategic plan to focus on its 25 core area oil and gas fields and to eliminate ancillary operations. Pioneer began discussions internally to consider a transaction involving the partnerships, including the basis for valuing the partnerships and whether the consideration should be Pioneer common stock, cash, or some combination of both. During the second quarter of 1998, Pioneer and Pioneer USA began to discuss the methods for valuing the partnerships. At that time, Pioneer USA engaged Sayles & Lidji, A Professional Corporation based in Dallas, Texas, as its independent legal counsel and discussed with them the procedures to be followed in evaluating various strategic alternatives available to Pioneer USA and responding to any expressions of interest received by Pioneer USA. Although Pioneer submitted an offer, the offer was withdrawn and the discussions were discontinued because of: - the decline in oil prices, which in turn would result in reducing any merger value to be paid to the limited partners; - the decline in Pioneer's stock price; and - the tight lending environment for many oil and gas companies, including Pioneer. As a result, each of Pioneer and Pioneer USA decided to discontinue further discussions and no transaction was submitted to the limited partners. As oil and gas prices improved, in June 1999, Pioneer and Pioneer USA again began discussions internally to consider a transaction involving the partnerships. At that time, Scott Sheffield, the President and Chief Executive Officer of Pioneer, contacted members of Pioneer USA's board regarding consideration of a potential transaction involving the partnerships. During the second quarter of 1999, Pioneer and Pioneer USA attempted to formally address the conflicting interests inherent in the relationships among Pioneer, Pioneer USA, the partnerships and the officers and directors of Pioneer and Pioneer USA. Pioneer USA caused the members of its board of directors who were also members of Pioneer's board of directors to resign from Pioneer USA's board of directors. Because all of the board members of Pioneer USA are also employees of Pioneer, an inherent conflict exits with respect to their duties to the limited partners in their capacity as directors of Pioneer USA, on the one hand, and their duties to Pioneer as employees, on the other hand. This separation of board processes may lessen, but does not eliminate, the inherent conflicting interests of the Pioneer USA directors in this transaction. We believe, however, that this separation enables the directors of Pioneer USA to more effectively consider and focus on the interests of the partnerships. Shortly thereafter, Pioneer USA's board again contacted Sayles & Lidji to advise the board in connection with the procedures to be followed in evaluating the merger transaction and any others, as well as various strategic alternatives available to Pioneer USA. The Pioneer USA board also engaged, on behalf of the partnerships, Robert A. Stanger & Co., Inc., as its financial advisor to advise the board on the fairness of the transaction from a financial point of view and to assist in Pioneer USA's evaluation of the merger transaction and other strategic alternatives. Robert A. Stanger & Co., Inc. was familiar with the circumstances from its 1998 engagement. On July 14, 1999, the board met with its counsel and Robert A. Stanger & Co., Inc. to discuss the proposed merger of the partnerships. Robert A. Stanger & Co., Inc. presented an overview of the analysis it planned to perform in evaluating the fairness of the proposed transaction. 12 20 Members of the Pioneer USA board met on several occasions during July and early August to discuss among each other the proposed terms of the merger transaction and other potential alternative transactions. On , 1999, Pioneer's board of directors met and voted to approve the mergers and to proceed with the completion of the mergers, subject to the September 30, 1999 pricing information and other relevant conditions at the time. On August 16, 1999, at a special meeting of the Pioneer USA board, the board met with representatives of Sayles & Lidji and Robert A. Stanger & Co., Inc. to discuss the terms of the proposed mergers. On August 17, 1999, Pioneer delivered a written proposal covering the merger transaction to the Pioneer USA board which outlined the terms of the proposed transaction. At a special meeting that day of the Pioneer USA board, the board, its counsel and Robert A. Stanger & Co., Inc. met to discuss the specifics of the merger proposal including oil and gas pricing, the present value discount rate, the right to allow others to bid on the property, and the costs of the mergers. Following the board meeting, our directors sought and obtained changes in the proposed terms which were advantageous to the partnerships. On August 23, 1999, at a special meeting of the Pioneer USA board, the board updated its counsel and Robert A. Stanger & Co., Inc. on the status of its discussions with Pioneer. Representatives of Robert A. Stanger & Co., Inc. provided the board with its review of the Pioneer proposal. Based partly on the analysis performed by Robert A. Stanger & Co., Inc., the board advised Pioneer that in the opinion of the Pioneer USA board, the discount rate used to determine the present value of future oil production should be reduced from 15% to 12.5%, thereby increasing the merger consideration to the limited partners. In response, Pioneer agreed to reduce the discount rate to 12.5%. On September 2, 1999, at a special meeting of the board, the board and representatives of Robert A. Stanger & Co., Inc. and Sayles & Lidji reviewed the terms of a revised merger proposal submitted by Pioneer. The parties discussed the terms of the merger, the strategic rationale for and benefits of the merger. At this meeting, Robert A. Stanger & Co., Inc. reviewed with the board its financial analysis and its evaluation of the merger consideration and the feasibility of other strategic alternatives. Robert A. Stanger & Co., Inc. also orally presented to the board the status of its findings and its preliminary evaluation of the proposed transaction. After considering Robert A. Stanger & Co., Inc.'s evaluation of the proposed merger transaction, the board, together with representatives of Robert A. Stanger & Co., Inc., engaged in a general discussion of other possible transactions it had considered over the last six to eight months. This discussion included anticipated ongoing operations of the limited partnerships under their current structure and the operation of the limited partnerships through a master limited partnership structure, as well as through a royalty trust. The board also discussed selling the oil and gas properties of the limited partnership at auction and potentially soliciting other buyers or merger partners. The board also considered the fact that other potential buyers of the limited partnerships would have an opportunity to make an offer for the limited partnerships before the board submitted the merger transaction to the limited partners for their consideration and approval. At a special meeting held on September 8, 1999, the Pioneer USA board discussed with Sayles & Lidji and Robert A. Stanger & Co., Inc. the complete terms of the proposed mergers. After considering other alternatives, including the advantages and disadvantages of each, the board concluded that none of the alternatives were more advantageous to the limited partners than the terms of the proposed mergers. The board then unanimously approved proceeding with the mergers, subject to determination of September 30, 1999, pricing, its receipt of Robert A. Stanger & Co., Inc.'s fairness opinion, and the board's determination that the merger consideration is fair to the limited partners based on all circumstances as of September 30, 1999, including without limitation, the then current market conditions and the existence, if any, of any other proposal for the partnerships on terms more favorable to the limited partners. 13 21 The foregoing discussion of these special factors considered by the Pioneer USA board is not exhaustive, but Pioneer USA believes it includes the material factors considered by its board. The board did not quantify or otherwise attempt to assign relative weights to the specific factors the board considered in reaching its determination to recommend the merger. Rather, the board viewed its position and recommendation as being based on the total information presented to and considered by the board. On September 8, 1999, Pioneer and Pioneer USA publicly announced the proposed mergers. In that announcement, Pioneer USA also announced that it would consider proposals from other potential buyers of the partnerships. In a special meeting of the board of Pioneer USA held on , 1999, Robert A. Stanger & Co., Inc. presented its opinion dated , 1999, expressing its opinion that the merger proposals are fair from a financial point of view to the limited partners of the partnerships. The board of Pioneer USA then unanimously determined that the merger proposals are advisable, fair to the limited partners and in the limited partners' best interests. Accordingly, the board recommended that the limited partners vote for the merger proposals. References to Pioneer USA's board's recommendation of the mergers and its finding that the merger consideration is fair from a financial point of view are stated in this preliminary document conditioned on the board making such determination after considering September 30, 1999, pricing information and other relevant conditions at the time. REASONS FOR THE MERGERS General. For all of the reasons listed below, Pioneer believes that it is the party in the position to pay the highest price for the limited partnership interests of the partnerships. Pioneer USA also believes that Pioneer is the most likely buyer for the partnerships' properties in light of: - Pioneer USA's operation of most of the properties; - Pioneer USA's extensive property holdings in the same fields; and - Pioneer's ability to achieve efficiencies by consolidating operations with its existing operations in the same areas. Pioneer's Reasons. Pioneer believes that completion of the mergers is advantageous to it for the following reasons: - Consolidate Core Area of Operations. The Spraberry field of the Permian Basin is one of Pioneer's 25 fields of focus in its strategic plan. Acquisition of the partnerships' properties would help consolidate Pioneer's operations in the Spraberry field and achieve operating efficiencies. Pioneer USA operates most of the partnerships' wells, and Pioneer has extensive properties around the partnerships' properties, including interests in most of the partnerships' wells. - Achieve Operating Efficiencies. Pioneer expects to improve operating efficiencies with respect to the properties acquired in the mergers because it will be able to co-mingle production from participating partnerships' properties with production from other Pioneer properties for storage, transportation and sale. Production from the partnerships' properties is currently kept segregated from Pioneer's production until sale. - Achieve Administrative Efficiencies. Pioneer will eliminate the costs, including time spent by Pioneer employees, related to preparing and filing the partnerships' separate tax returns, financial statements, and reports with the SEC, as well as dealing with the concerns of approximately 25,000 record limited partners. The mergers will result in administrative efficiencies and cost reductions in the management and operation of the properties now owned by the partnerships, particularly in the areas of audit, accounting and tax services, engineering services, bookkeeping, data processing, record maintenance and mailing information to the partners. Although Pioneer will lose the benefit of the partnerships' reimbursement for general and administrative expenses, it will be able to use the additional time of its personnel to help achieve its corporate strategic goals. 14 22 Pioneer USA's Reasons. In considering the mergers, the board of directors of Pioneer USA also considered the benefits to the limited partners set forth on page 4 as well as the following factors: - Maturity of Partnership Properties. Although the partnerships' properties were long-lived at the formation of the partnerships, Pioneer and Pioneer USA anticipated that at some point the partnerships would need to be liquidated. The partnerships' properties have matured, and the mergers provide (1) liquidity to the limited partners, and (2) a means for Pioneer, through its subsidiary, Pioneer USA, to liquidate the partnerships. - Declining Cash Flows. As the partnerships' properties have matured, the net cash flows from operations have generally declined. See Table 7 of Appendix A. The marginal benefit of continuing operations of the partnerships is offset by the related administrative costs. These administrative costs consume an increasing amount, and ultimately will consume the entire amount, of the cash flows as production declines. - Tax Incentives Have Been Realized. To the extent that the partnerships were intended to provide tax incentives to the partners, those incentives have been realized, or the tax purposes for which the partnerships were originally formed are no longer applicable as a result of changes in laws. - Partnership Tax Burdens May Now Exceed Benefits. As net cash flow available for distribution has declined or, at times, disappeared, some limited partners may incur greater costs to include their share of the partnerships' tax information in their returns than they receive in cash distributions. In any event, all limited partners are expected to benefit by the elimination of the obligation to include partnership information in their tax returns for the years after the mergers. - Partnerships Unable to Access Additional Capital. Pioneer, through its subsidiary, Pioneer USA, has the ability, financial and otherwise, to take advantage of corporate opportunities to expand its reserve base through acquisitions. The partnerships do not have the ability to raise capital for reserve acquisitions. The partnership agreements of the partnerships do not authorize the partnerships to raise additional capital, whether debt or equity. Even if the partnership agreements were amended to authorize additional capital, Pioneer does not believe that the limited partners would desire to contribute additional capital or to apply all cash flow to debt service, while remaining taxable on the related income. - Fairness of Price. Pioneer USA's board of directors determined, based in part on the fairness opinion of Robert Stanger & Co., Inc., that the mergers are advisable, fair to the limited partners and in their best interests. Pioneer USA's board of directors also considered the following factors: -- The form and amount of consideration offered to the partners; -- The objectives of the mergers, including providing liquidity to the partners; and -- Its right to consider third-party offers. RECOMMENDATION OF PIONEER USA Pioneer USA's board of directors unanimously determined that the mergers are advisable, fair to the limited partners of each partnership, and in the limited partners' best interests. PIONEER USA'S BOARD OF DIRECTORS RECOMMENDS THAT THE LIMITED PARTNERS VOTE FOR THE MERGER PROPOSALS. In making this recommendation, Pioneer USA's board of directors considered a number of factors, including the reasons for the mergers set forth above in "Special Factors -- Reasons for the Mergers" and the matters, such as its conflicting interests, described under "Risk Factors" beginning on page 8 of this document. In view of the numerous factors taken into consideration, Pioneer USA's board of directors did not consider it practical to, and did not attempt to, quantify or assign relative weights to the factors considered by it in reaching its decision. Pioneer USA's board of directors also considered the likelihood, benefits and costs of other transactions, including third-party offers. Pioneer USA will consider any offers from third parties to purchase any partnership or its assets, whether one of the publicly-held partnerships 15 23 discussed in this document or one of the non-public or employee partnerships. See "The Mergers -- Third-Party Offers" on page 32 of this document for a description of the procedures for these offers. FAIRNESS OPINION Pioneer USA, on behalf of the partnerships, engaged Robert A. Stanger & Co., Inc., an independent financial advisory firm to conduct an independent review and deliver a written opinion of its determination of the fairness, from a financial point of view to the limited partners of the partnerships, of the merger values to be paid in cash for limited partner interests in each partnership in connection with the mergers. The full text of the fairness opinion, which contains a description of the assumptions, limitations and qualifications applicable to the review by Stanger is set forth in Appendix C to this document and should be read in its entirety. The material assumptions and qualifications to the fairness opinion are summarized below. This summary does not purport to be a complete description of the various inquiries and analyses undertaken by Stanger in rendering the fairness opinion. Stanger has advised us that arriving at a fairness opinion is a complex analytical process not necessarily susceptible to partial analysis or amenable to summary description. For a more complete description of the assumptions and qualifications to the fairness opinion see "Qualifications to Fairness Opinion" and "Assumptions" below. Except for certain assumptions which Pioneer USA and the partnerships advised Stanger would be reasonable and appropriate in their view, Pioneer USA and the partnerships imposed no conditions or limitations on the scope of the investigation by Stanger or the methods and procedures to be followed by Stanger in rendering the fairness opinion. In addition, the partnerships have agreed to indemnify Stanger against certain liabilities arising out of Stanger's engagement to prepare and deliver its opinion upon consummation of the mergers, and such indemnification obligations will become obligations of Pioneer USA. Experience of Stanger. Since its founding in 1978, Stanger has provided information, research, investment banking and consulting services to clients located throughout the United Sates, including major New York Stock Exchange member firms and insurance companies and over seventy companies engaged in the management and operation of partnerships. The investment banking activities of Stanger include financial advisory and fairness opinion services, asset and securities valuations, industry and company research and analysis, litigation support and expert witness services, and due diligence investigations in connection with both publicly registered and privately placed securities transactions. Stanger was selected because of its experience in the valuation of businesses and their securities in connection with mergers, acquisitions, reorganizations and for estate, tax, corporate and other purposes, including the valuation of partnerships, partnership securities and the assets typically held through partnerships including oil and gas assets. Pioneer USA has previously engaged Stanger to provide financial advisory services in connection with proposed transactions between the partnerships and Pioneer which were never consummated. Qualifications to Fairness Opinion. In the fairness opinion, Stanger specifically states that Stanger was not requested to, and did not: - make any recommendations to Pioneer USA, the partnerships or the limited partners with respect to whether to approve or reject the mergers; - determine or negotiate the amount or form of the merger values to be paid for limited partners' interests in the mergers; - offer the assets of the partnerships for sale to any third party; - express any opinion as to: -- the impact of the mergers with respect to Pioneer USA or the limited partners of any partnerships that do not participate in the mergers; -- the tax consequences of the mergers for Pioneer USA or the limited partners of any partnership; 16 24 -- Pioneer's or Pioneer USA's ability to finance their obligations pursuant to the merger agreement or the impact of a failure to obtain financing on the financial performance of Pioneer, Pioneer USA or the partnerships; -- Pioneer USA's decision to estimate the reserve value of the oil and gas reserves of each partnership based upon the continued operation of the properties by Pioneer USA and the payment of general and administrative and overhead charges in accordance with existing operating agreements or the impact, if any, on the estimated values of the partnerships' oil and gas reserves if Pioneer USA and Pioneer determined to offer or operate the assets subject to revised operating agreements; -- whether or not alternative methods of determining the merger values would have also provided fair results or results substantially similar to the methodology used; -- alternatives to the mergers, including the offering of such assets for sale to third-party buyers; -- the fairness of the amount or allocation of merger costs; or -- any other terms of the mergers. Summary of Material Considered and Investigation Undertaken. Stanger's analysis of the mergers involved a review of the following information: - a draft of the merger agreement which Pioneer USA intends to execute in connection with the mergers; - financial statements of the partnerships for the years ended December 31, 1997 and 1998 and the six months ended June 30, 1999; - reserve analysis of each partnership prepared by Pioneer USA and Pioneer as of , 1999; - consultant's report for each partnership prepared by as of , 1999; - calculations prepared by Pioneer USA and Pioneer of the merger values per unit of limited partner interest in each partnership; and - estimates prepared by Pioneer USA and Pioneer of the going-concern value and liquidation value per unit of limited partner interest in each partnership. In the course of its analysis, Stanger conducted interviews of senior management personnel of Pioneer USA in July and August 1999. During such interviews, Stanger and the senior management personnel reviewed the status of the mergers, the reserve pricing and related value estimates, the estimated timing of the mergers and other matters. Stanger reviewed estimates of merger values, going-concern value, and liquidation value prepared by Pioneer USA with respect to each partnership. In addition, Stanger reviewed secondary market prices, as tracked by Stanger, for limited partner interests in each partnership along with tender offers received by limited partners as derived from data provided by Pioneer USA. Stanger's analysis is summarized below. Review of Merger Value. Stanger reviewed the calculation of merger values prepared by Pioneer USA. Stanger observed that such calculation includes the reserve value, as described below, other current assets as of 1999, reduced by other current liabilities as of 1999 and allocable merger costs as determined by Pioneer USA. Stanger reviewed the balance sheet of each partnership as of 1999 as prepared by Pioneer USA, and reconciled the current assets and current liabilities on such financial statements to the balances included on the merger value calculation for each partnership. With respect to merger costs, Stanger observed that Pioneer USA allocated the estimated aggregate merger cost of approximately $4.6 million among the partnerships based upon such partnership's relative reserve value. 17 25 Stanger reviewed the summary reserve analysis prepared by Pioneer USA and Pioneer with respect to each partnership and compared such data to the reserve analysis prepared as of December 31, 1998. Stanger noted that the reserve analysis was prepared based upon a pricing case consistent with the average five-year NYMEX future price for oil and the NYMEX price of $2.40 per Mcf of gas, as adjusted by Pioneer USA to reflect oil quality, BTU content, oil and gas gathering and transportation costs, and gas processing costs and shrinkage. Stanger further observed that the reserve analysis utilized a discount rate of 12.5% and resulted in a per barrel of oil equivalent, or BOE, value of the reserves for the partnerships ranging from to . Stanger observed that such values are low by general industry averages. However, Stanger observed that such properties are generally low-volume long-lived properties, not operated by the partnerships, and are subject to overhead charges by the operator, Pioneer USA. In the course of its engagement, Stanger reviewed selected comparable transactions in the BOE value range described above for long-lived, generally low-volume properties. Stanger reviewed the report prepared by Williamson Petroleum Consultants, Inc. relating to the reserves of the partnerships. Such report indicated that such analyses were prepared using industry standards and procedures, based upon the pricing case provided. Going Concern Value. Stanger reviewed the going concern value calculation prepared for each partnership by Pioneer USA. Such going concern value was based upon the estimated net cash flow from sale of the reserves during a 10-year operating period less partnership level general and administrative expenses equal to 3% of revenues except for certain partnerships where 2% was utilized consistent with 1998 and 1999 expense levels. Such cash flows plus the residual value from the sale of the remaining reserves at the end of the operating period were discounted to present value at a discount rate of 12.5%. Stanger observed that the going concern value of each partnership ranged from % to % less than the merger values. Liquidation Value. Stanger reviewed the liquidation value calculation prepared for each partnership by Pioneer USA. Such liquidation value was based upon sale of the reserves at the reserve value, less additional merger expenses estimated at 3% of reserve value. Stanger observed that such merger expenses are intended to reflect Pioneer USA's estimate of the cost associated with brokers commissions on asset sales and the additional wind-down costs of the partnership. Stanger observed that the liquidation value for each partnership ranged from % to % less than the merger values. Secondary Market Prices. Stanger reviewed the secondary market prices for units of limited partner interests in the partnerships during the seven months ended July 31, 1999, collected from data maintained on partnerships by Stanger. Stanger observed that secondary market transactions were reported for 24 of the partnerships during such period and the weighted average price of such units represents an average discount to the merger values for the partnerships of %. Stanger advised us that its data indicates that participants in the secondary market reported only one trade of five units on one partnership (Parker & Parsley 90-B Conv. L.P.) at a price which exceeds the merger values. The merger value of such partnership is $158.61 and the reported trade of five units was at $171.00 per $1,000 investment. Stanger advised Pioneer USA that the secondary market is illiquid and that trading activity is sporadic and frequently takes place at substantial discounts to the underlying asset value. Selected Tender Offers. Stanger observed that Pioneer USA reported unsolicited tender offers for three of the partnerships during the past two years. Stanger observed that the tender offers and related merger values per limited partners interest were as follows: MERGER VALUE TENDER OFFER (PER $1,000 (PER $1,000 INVESTMENT) INVESTMENT) DISCOUNT TO MERGER VALUE ------------ ------------ ------------------------ PARKER & PARSLEY 83-B................................... $ 96.42 $50.00 51.86% 87-B................................... 131.44 60.00 45.65 88-A................................... 170.38 80.00 46.95 18 26 Stanger observed that the above tender offers represent a discount to the merger values of 45.65% to 51.86% and average 48.15%. Stanger also observed that tender offers for limited partnership securities are generally at prices which represent a substantial discount to the underlying value of the assets held by such partnerships. Assumptions. Pioneer USA and Pioneer advised Stanger that the oil and gas properties owned by the partnerships are subject to operating agreements with Pioneer USA and that: - such operating agreements provide for the payment of overhead charges and that such charges are reasonable compared with amounts charged for similar services by third-party operators; - except for cause, such operating agreements do not provide for the termination of Pioneer USA as operator; and - such operating agreements do not provide for the revision of the overhead charges, except as escalated under the terms of such operating agreements. Furthermore, Pioneer USA and Pioneer advised Stanger that if each partnership's reserves were offered for sale to a third party, a condition of such sale would be that the oil and gas reserves would continue to be subject to the operating agreements with Pioneer USA which provide for the payment of overhead charges, and that it would be appropriate to assume, when estimating the value of such reserves, that such charges would continue. In addition, Pioneer USA and Pioneer advised Stanger that the reserve value and working capital balance of each partnership has been properly allocated between the general partners and the limited partners of each partnership in accordance with the partnership agreement with respect to a liquidation. Stanger did not conduct any engineering studies and has relied on estimates of Pioneer USA and Pioneer with respect to oil and gas reserve volumes, prices, operating costs, general and administrative expenses and overhead charges with respect to the reserve value estimates. Stanger also relied on the assurance of Pioneer USA, Pioneer and the partnerships that: - the reserve analysis provided to them was in the judgement of Pioneer USA and the partnerships reasonably prepared on bases consistent with actual historical experience and reflect their best currently available estimates and good faith judgements; - any estimates of costs to remediate environmental conditions included in the reserve analysis are based on detailed analyses and reflect the best currently available estimates and good faith judgements; - any historical financial data, balance sheet data, merger cost estimates, merger value analysis, going concern value analyses and liquidation value analyses are accurate and complete in all material respects; - all calculations of reserve values, working capital balances, merger values, going concern values and liquidation values have been made in accordance with the partnership agreement for each partnership; - no material changes have occurred in the information reviewed or in the value of the oil and gas reserves or working capital balances of each partnership between the date the information was provided to Stanger and the date of Stanger's opinion; and - Pioneer USA, Pioneer and the partnerships are not aware of any information or facts regarding the partnerships, the oil and gas properties, the reserve analysis or the working capital balances of each partnership that would cause the information supplied to Stanger to be incomplete or misleading in any material respect. 19 27 Stanger's opinion is based upon business, economic, oil and gas market and other conditions as of the date of its analysis and addresses the merger values in the context of information available as of the date of Stanger's analysis. Events occurring after the date of Stanger's analysis could affect the value of the assets of the partnerships or the assumptions used in the preparation of Stanger's fairness opinion. Conclusions. Stanger concluded that, based upon and subject to its analysis, assumptions, limitations and qualifications cited in its opinion, and as of the date of the fairness opinion, the merger value to be paid in cash for the limited partner interests in connection with the mergers is fair from a financial point of view to the limited partner of each respective partnership. Compensation and Material Relationships. Stanger has been paid a fee of $200,000 in connection with the rendering of the fairness opinion. Such fee was not conditioned on Stanger's findings and is payable whether or not the mergers are consummated. In addition, Stanger will be reimbursed for all reasonable out-of-pocket expenses, including legal fees, and will be indemnified against certain liabilities including certain liabilities under the securities laws. During the past two years, the partnerships had engaged Stanger to render financial advisory services in connection with proposed transactions which were withdrawn and never consummated. In connection with such assignments Stanger was paid fees aggregating $125,000. ALTERNATIVE TRANSACTIONS TO THE MERGERS We considered the following alternative types of transactions before selecting the merger transaction described in this document. As discussed below, we believe that the mergers are the best available alternative for the partnerships to maximize the value of the partnerships' property interests. Comparison of the Mergers to Continuing Operations. Because the partnerships' properties are mature, producing properties, we believe that production from those properties will continue to decline at the rate predicted in the partnerships' oil and gas engineering reserve reports. Accordingly, cash distributions from the partnerships will also decline, subject to variation for changes in oil and gas prices. The marginal benefit of continuing operations of the partnerships is offset by the general and administrative costs related to continuing operations. See "Special Factors -- Reasons for the Mergers" beginning on page 14 of this document. We also believe there is a substantial advantage in receiving the liquidating distribution in one lump sum currently. We believe that the reserve values included in the merger values are higher than the net present value of estimated future cash distributions to the limited partners from continued operations because the reserve values have not been reduced for the reimbursement of Pioneer USA's general and administrative expenses allocable to each partnership. In addition, the estimates of distributions from continued operations are based upon current oil and gas prices. It is likely that over a long period of time, oil and gas prices will vary often and possibly widely, as has been demonstrated historically, from the prices used to prepare these estimates. Continued operations over a long period of time subject the limited partners to the risk of receiving lower levels of cash distributions if oil and gas prices over this period are lower on average than those used in preparing the estimates of cash distributions from continued operations. Continued operations also subject the limited partners' potential distributions to the risk of price volatility and to possible changes in costs or need for workover or similar significant remedial work on the partnerships' properties. We also believe that there is an advantage to the limited partners taking cash which can be redeployed in other investments, rather than continuing to receive decreasing levels of cash distributions over a long period of time. We expect that nonparticipating partnerships will continue operations and will produce their respective reserves until depletion with steadily decreasing rates of cash flow and, as a result, decreasing cash distributions. Comparison of the Mergers to Master Limited Partnership. We considered accomplishing the consolidation of the partnerships through a master limited partnership, pursuant to which the partnership interests of the limited partners would be exchanged for interests in the master limited partnership. 20 28 However, the partnerships' oil and gas properties are not of sufficient size in the aggregate to attract new capital through a master limited partnership. In addition, the partnership interests in a master limited partnership might not be traded on a national stock exchange or in any other significant market. Some master limited partnership interests might be sold from time to time in private or over-the-counter transactions, but the prices would likely reflect a discount for illiquidity. As a result, a master limited partnership would not provide the limited partners with immediate and complete liquidity for their investment in the partnerships. Finally, a master limited partnership would still be burdened with general and administrative expenses, which would reduce any cash distributions paid to the partners of the master limited partnerships. The merger values reflect liquidation values and have not been reduced for any reimbursement of Pioneer USA's general and administrative expenses allocable to the partnerships. Comparison of the Mergers to Royalty Trust. We also considered a royalty trust, pursuant to which the partnership interests would be exchanged for beneficial ownership interests in the trust. Like the master limited partnership alternative discussed above, the partnerships' oil and gas properties are not of sufficient size in the aggregate to attract new capital through a royalty trust. In addition, the beneficial ownership interests in a royalty trust might not be publicly traded in a significant market. As a result, this alternative was not selected because it would not result in immediate and complete liquidity for the partners' investments in the partnerships. Finally, a royalty trust would still be burdened with general and administrative expenses, which would reduce any cash distributions paid to the beneficiaries of the royalty trust. The merger values reflect liquidation values and have not been reduced for any reimbursement of Pioneer USA's general and administrative expenses allocable to the partnerships. Comparison of the Mergers to Auction. Offering oil and gas properties for sale at auction is often an efficient means of selling smaller interests in properties in which the seller is not the operator of the property. However, auctions are generally unsuited to the offer and sale of substantial property interests such as those owned by the partnerships, which exceed the normal size of properties offered at auction, and might well be beyond the purchasing capacity of the parties which typically are bidders at auctions. Attempting to auction such properties would cause such properties to dominate each auction and would likely lower the price or the number of interested bidders. In order to avoid this consequence, the partnerships' interests in properties could be divided into smaller pieces and offered at auction on multiple occasions over several years. That extended auction might be counterproductive in terms of prices received, thus minimizing many of the benefits of selling properties at auction. Comparison of the Mergers to Negotiated Sale. We also considered whether the partnerships would benefit from attempting to sell their property interests in negotiated transactions. Buyers would be purchasing many partnerships' property interests which they would neither control nor operate. A portion of the value of the properties in which the partnerships own interests would continue to be operated by Pioneer USA because Pioneer USA controls other interests in fields in which the partnerships' properties are located. Because of Pioneer USA's control of such properties, Pioneer and Pioneer USA believe Pioneer is the party in the position to pay the highest price for such interests and the one most likely to do so. In contrast, Pioneer USA's control of such properties could negatively affect the amount a third party is willing to pay and the overall interest of third parties in buying such properties. In addition, sale of the partnerships' properties on a direct basis often involves substantial periods of time for due diligence, negotiation and execution of agreements and closings, often with different purchasers for different properties. Satisfying due diligence requests requires large amounts of time to create and supervise data rooms or disseminate data to possible purchasers, plus the time needed to deal directly with multiple prospective purchasers. Furthermore, some issues, such as environmental and title matters, may come to light in the late stages of a negotiated sale, which may delay or preclude the consummation of the sale. 21 29 The transaction costs for offering properties in a negotiated sale could be substantial, and often are higher than other means of sale. Those costs include: - preparing and disseminating information on properties to be offered; - soliciting attendance by prospective purchasers; and - screening and qualifying purchasers. Although we believe the factors described above to be true, we will consider third party offers to purchase any partnership or its assets. See "Third-Party Offers" on page 32. CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION Pioneer and Pioneer USA caution you that this document, any supplement and other statements Pioneer or Pioneer USA make from time to time contain statements that may constitute "forward-looking statements." Those statements include statements regarding Pioneer's and Pioneer USA's intent, belief or current expectations, as well as the assumptions on which those statements are based. Forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and actual results may differ materially from those contemplated by forward-looking statements. Important factors currently known to Pioneer and Pioneer USA's management that could cause actual results to differ materially from those in forward-looking statements include, but are not limited to, those factors set forth from time to time in reports the partnerships filed with the Securities and Exchange Commission. Some of these factors are also described in "Risk Factors" beginning on page 8 of this document. Except as required by law, Pioneer and Pioneer USA undertake no obligation to update or revise forward-looking statements to reflect changes in assumptions, the occurrence of unanticipated events or changes to future operating results over time. You are cautioned not to place too much reliance on such statements. METHOD OF DETERMINING MERGER VALUES AND AMOUNT OF CASH OFFERED Pioneer and Pioneer USA agreed to merger values for each of the partnerships for purposes of the mergers. The method of determining merger values was not determined by arm's-length negotiations. See "Risk Factors -- You Were Not Independently Represented in Establishing the Terms of the Mergers" on page 9 and "Interests of Pioneer, Pioneer USA and Their Directors and Officers" on page 43. COMPONENTS OF MERGER VALUES The merger value assigned to each partnership was calculated as follows: - Pioneer and Pioneer USA calculated the volumes of the partnership's proved reserves as of June 30, 1999, based on a future production curve consistent with the production curve used in the reserve report of Williamson Petroleum Consultants, Inc. as of December 31, 1998. Pioneer and Pioneer USA ignored any economic limit, or point at which production would become unprofitable, otherwise assumed in the 1998 Williamson reserve report because that reserve report used NYMEX oil and gas prices as of December 31, 1998, which were $12.00 per Bbl of oil and $2.00 per Mcf of gas. In contrast, Pioneer and Pioneer USA used (1) an arithmetic average of the five-year NYMEX futures price as of June 30, 1999, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments, to calculate the merger values. Based on this pricing, production could continue profitably for a longer period of time than assumed in the 1998 Williamson reserve report. - Pioneer and Pioneer USA calculated estimated future net revenues from the estimated reserves at June 30, 1999, using (1) an arithmetic average of the five-year NYMEX futures price for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the 22 30 NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments. Pioneer and Pioneer USA adjusted the estimated future net revenues for standard industry price adjustments, including: -- production costs; -- the effects of oil quality; -- BTU content for gas; -- oil and gas gathering and transportation costs; and -- gas processing costs and shrinkage. Those adjustments reflect assumptions about the costs to extract, transport and process, if necessary, crude oil, natural gas liquids and natural gas to their point of sale. - Pioneer and Pioneer USA calculated the present value of the estimated future net revenues using a 12.5% discount rate. - Pioneer and Pioneer USA added the present value of the partnership's estimated future net revenues as of June 30, 1999 to the partnership's net working capital as of June 30, 1999, as reduced by its pro rata share, based on its reserve value, of the estimated expenses and fees of the mergers of all of the partnerships, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document. Appendix B to this document contains a summary of the 1998 Williamson reserve report for the partnerships, including assumptions used in the preparation of that report. Pioneer and Pioneer USA will update the information presented in this document from June 30, 1999 to September 30, 1999 before mailing this document to the limited partners. Robert A. Stanger & Co., Inc. will review the September 30, 1999 data and determine if it can give its fairness opinion based on that data. Likewise, Pioneer USA's board of directors will make its determination as to whether the mergers are advisable, fair to the limited partners, and in their best interests based on the September 30, 1999 data. From the mailing date of this document to the closing date of the mergers, neither Pioneer nor Pioneer USA will adjust any of the components of the merger values. Estimated Reserve Volumes. Pioneer and Pioneer USA believe it is appropriate to calculate estimated reserve volumes at June 30, 1999. Pioneer and Pioneer USA estimate that the mergers will be consummated in the latter half of December 1999, but before a 1999 year-end reserve report can be prepared in accordance with the guidelines of the SEC. However, because the properties are long-lived, mature, producing properties, Pioneer and Pioneer USA believe the production curve used in preparing the reserve values as of June 30, 1999 is similar, in all material respects, to the production curve in the 1998 Williamson reserve report. Estimated Future Net Revenues. Pioneer and Pioneer USA agreed to calculate estimated future net revenues of the estimated reserves at June 30, 1999, using (1) an arithmetic average of the five-year NYMEX futures price for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments. Pioneer and Pioneer USA used production costs consistent with those assumed in the 1998 Williamson reserve report. Pioneer and Pioneer USA believe it is appropriate to use production costs similar to those assumed in the 1998 Williamson reserve report because such costs have been fairly stable and predictable over the last several years. Present Value of Estimated Future Net Revenues. Pioneer and Pioneer USA agreed to use a 12.5% discount rate to determine the present value of estimated future net revenues from each partnership's reserves. Pioneer and Pioneer USA believe 12.5% is a rate within the range of discount rates commonly used in the oil and gas industry in property acquisitions of producing properties, although it is higher than 23 31 the 10% rate that the SEC requires for comparative purposes in the year-end reports of publicly traded oil and gas companies. None of the partnerships has any material long-term gas contracts. Pioneer and Pioneer USA estimated future operating costs based on costs in effect at December 31, 1998. In addition, Pioneer and Pioneer USA do not believe that the present value of any partnership's proved reserves is significantly affected by curtailments of gas production. The reserve estimates do not reflect the effect of any "take-or-pay" clauses in gas contracts, which effect we expect to be insignificant. Net Working Capital. No cash distributions will be made by the partnerships to their partners after September 30, 1999 through the closing date or termination date of the mergers. The cash payments of the merger values to limited partners of the participating partnerships already reflect those distributions. However, any cash distributions by a nonparticipating partnership which would have been paid during that time period in the ordinary course of that partnership's business will be distributed to its partners at the same time that checks are mailed to the partners, other than Pioneer USA, of participating partnerships. The merger values have been reduced by the estimated expenses and fees of the mergers of the partnerships, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document. Since the merger values include net working capital, the merger values assigned to the partnerships include the partnerships' assets and liabilities other than their oil and gas reserves. The partnerships' other assets and liabilities consist mainly of cash, accounts receivable from the sale of oil and gas production and accounts payable. Pioneer USA will assume all of the liabilities, including contingent liabilities and obligations, of the participating partnerships as of the closing date of the mergers. As of the date of this document, Pioneer USA is not aware of any material contingent liabilities to which any partnership is subject. ALLOCATION OF MERGER VALUES AMONG PARTNERS In determining the portion of the merger value attributable to each $1,000 of initial limited partner investment in a partnership, Pioneer determined the amount payable per $1,000 investment as if the assets of the partnership had been sold on June 30, 1999 for cash equal to the merger value and the proceeds distributed in accordance with the liquidation provisions of the partnership's partnership agreement. If Pioneer USA were to receive any cash payment in the mergers, this methodology would result in Pioneer USA receiving an equal amount or a lesser amount than it would have received if the aggregate merger value was allocated among the partners based on the revenue-sharing provisions of the partnership agreement. OTHER METHODS OF DETERMINING MERGER VALUES Pioneer and Pioneer USA believe that the method used to determine the merger values is a fair and reasonable method of valuing the partnerships' properties. Pioneer and Pioneer USA considered a number of alternative methods of determining the merger values before selecting a method. However, this method might not accurately reflect the value of the partnerships' assets. See "Risk Factors -- The Merger Values Involve Estimates that Will Not Be Adjusted" on page 8. The following alternative methods for determining the merger values should be taken into account in assessing the adequacy of this method: Book Value of Assets. Pioneer and Pioneer USA did not base the calculation of merger values on the net book value of the partnerships' assets. The net book values of the partnerships' assets are based upon the financial statements reported in accordance with generally accepted accounting principles. The net book values are not adjusted for estimates in changes in the fair market value of the assets. For this reason, Pioneer and Pioneer USA believe that the merger values are more indicative of the fair market value of the assets of the partnerships than the assets' net book values. 24 32 Trading Price of Units. None of the partnership interests are traded on a national stock exchange or in any other significant market. Although some partnership interests are occasionally sold in private or over-the-counter transactions, Pioneer and Pioneer USA believe any market for the partnership interests: - is highly illiquid; - reflects an illiquidity discount; and - as a result, is not reliable as an indicator of value. As a result, Pioneer and Pioneer USA did not base the calculation of merger values on recent trading prices of partnership interests in the partnerships. See Table 14 of Appendix A for historical information about recent trades of partnership interests in the partnerships. Repurchase Offers. Pioneer and Pioneer USA did not base the calculation of merger values on the price of recent repurchase offers in the partnerships. Most partnerships do not have a repurchase offer obligation, so no repurchase price information was available for those partnerships. The merger values are higher than the 1999 repurchase offer prices for the few partnerships that had such requirements because the repurchase prices were based on NYMEX oil and gas prices as of December 31, 1998, which were $12.00 per Bbl of oil and $2.00 per Mcf of gas. In contrast, the merger values are based on (1) an arithmetic average of the five-year NYMEX futures price for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments. See "Risk Factors -- Repurchase Rights Terminate on Completion of the Mergers" on page 10 of this document. Timing of Pricing. Pioneer and Pioneer USA did not calculate the merger values using December 31, 1998 oil and gas prices. Oil and gas prices declined significantly in 1998, which adversely affected the cash distributions that limited partners had been receiving. However, oil and gas prices have recovered from NYMEX oil and gas prices of $12.00 per Bbl of oil and $2.00 per Mcf of gas as of December 31, 1998, to (1) an arithmetic average of the five-year NYMEX futures price for oil as of June 30, 1999, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, and (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments. Pioneer and Pioneer USA used those recovered oil and gas prices to calculate the merger values. Although Pioneer and Pioneer USA expect that long-term oil and gas prices will not increase materially above the prices used in calculating the merger values, no assurance can be given that prices will not increase significantly in the future. Significant increases in future prices would increase cash available for distribution from the partnerships and could, in retrospect, suggest that the merger values were low by comparison. INFORMATION SOURCES Pioneer used the records of Pioneer USA and the partnerships to derive the information regarding: - the ownership interests; - prices being received or contracted for; - costs; - production; - allocation of revenues and costs between classes of partners; - capital accounts of partners; and - other factual data used by Pioneer: -- to prepare its estimates of proved reserves; -- to compute the merger values; and -- to determine the allocation among partners of the cash payment to be received. 25 33 While Pioneer has implemented procedures designed to verify some of this information, the nature and volume of data preclude verification of all information. In addition, information relating to prices, costs and production history frequently is estimated based on incomplete data and is subject to varying interpretations. Likewise, the provisions of some of the partnership agreements are subject to different interpretations. In allocating the merger value assigned to a partnership among its partners, Pioneer and Pioneer USA attempted to apply a reasonable interpretation of those provisions. 26 34 THE MERGERS GENERAL Immediately before the effective time of each merger, the partnership agreement for each participating partnership will be amended by the merger amendment to permit the merger of the partnership with and into us. At the effective time of the mergers, the participating partnerships will be merged with and into us. We will be the surviving entity. In addition, at the effective time of the mergers, each of your partnership interests in a participating partnership will be converted into the right to receive cash. The amount of cash you receive: - will be based on the merger values assigned to the partnerships; and - will equal the amount that you would have received on liquidation of the partnerships if the partnerships' assets had been sold on June 30, 1999 for cash equal to the merger values. The merger value of a partnership is equal to the partnership's reserve value and its net working capital, as reduced by its pro rata share of the estimated expenses and fees of the mergers, in each case as of June 30, 1999. The reserve value is based on the present value of estimated future cash flows from the partnership's reserves at June 30, 1999, using (1) an arithmetic average of the five-year NYMEX futures price for oil, which was approximately $18.00 per Bbl of oil, less standard industry adjustments, (2) the NYMEX price of $2.40 per Mcf of gas, less standard industry adjustments, and (3) a 12.5% discount rate. Pioneer and Pioneer USA agreed to use September 30, 1999 to determine the merger values because that will be the most recent quarter-end preceding the date on which Pioneer USA mails this document to the limited partners. However, to provide an example in this preliminary document, Pioneer and Pioneer USA calculated the merger values as of June 30, 1999. Pioneer and Pioneer USA intend to revise those numbers as of September 30, 1999 prior to mailing this document to the limited partners. LEGAL OPINION FOR LIMITED PARTNERS All of the partnership agreements require that special legal counsel render an opinion on behalf of the limited partners to Pioneer USA that neither the grant nor the exercise of the right to approve the mergers by the limited partners will adversely affect the tax status of the partnerships. In addition, some of the partnership agreements require an opinion that such an approval will not result in the loss of any limited partner's limited liability. For some partnerships, the counsel designated to render the opinion must be counsel other than counsel to Pioneer USA or the partnerships. In all cases, the designated counsel and the legal opinion must be approved by the limited partners. Pioneer USA has retained of Dallas, Texas for the purpose of rendering this legal opinion on behalf of all of the limited partners to Pioneer USA. The merger proposals include an approval of that counsel and the form of its opinion. See "The Special Meetings -- Time and Place; Purpose" on page 39 of this document. A copy of the opinion is attached as an exhibit to the merger proposals. DISTRIBUTION OF CASH PAYMENTS Upon completion of the mergers, the partners will have no continuing interest in, or rights as partners of, any participating partnership. The transfer books of each participating partnership will be closed on the closing date of the mergers. All partnership interests in the participating partnerships will cease to be outstanding, will automatically be cancelled and retired, and will cease to exist. The certificates previously representing partnership interests in participating partnerships held by record partners will represent only the right to receive cash. We intend to mail checks to the partners of record promptly following the effectiveness of the mergers in payment of the merger values. Partners will not be required to surrender partnership interest certificates to receive the cash payment. 27 35 MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES The following discussion summarizes the material federal income tax considerations of a conversion of partnership interests into cash pursuant to the mergers. The federal tax consequences of the mergers will vary for each limited partner because of the different circumstances of each participating partnership and the individual federal income tax position of each limited partner. The following discussion is based upon current law. Future legislative, judicial or administrative changes or interpretations could alter or modify the following statements and conclusions, and any of these changes or interpretations could be retroactive and could affect the tax consequences to the limited partners. The following discussion is not exhaustive of all possible tax considerations. It does not address any state, local or foreign tax considerations, nor does it discuss all of the aspects of federal income taxation that may be relevant to specific partners in light of their particular circumstances. The discussion below describes general federal income tax considerations applicable to individuals who are citizens or residents of the United States, and therefore has limited application to domestic corporations and persons subject to specialized federal income tax treatment, such as foreign persons, tax-exempt entities, regulated investment companies and insurance companies. YOU ARE ADVISED TO CONSULT YOUR OWN TAX ADVISOR TO DETERMINE ALL OF THE RELEVANT FEDERAL, STATE AND LOCAL TAX CONSEQUENCES OF THE MERGERS TO YOU. THE FOLLOWING DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING, AND YOU MUST DEPEND UPON THE ADVICE OF YOUR OWN TAX ADVISOR CONCERNING THE EFFECTS OF THE MERGERS. Tax Consequences of a Conversion of Partnership Interests. - Generally. As more fully described below, if you own partnership interests in a participating partnership, you will generally recognize an aggregate amount of net gain or loss equal to the difference between the amount of cash you receive in the mergers and your adjusted tax basis in your partnership interests immediately prior to the mergers. That net gain or loss may be comprised of ordinary income or ordinary loss depending upon the extent of any recapture of depletion or intangible drilling and development costs and any appreciation or depreciation in the ordinary assets of the partnership. The recognition of ordinary income will decrease the capital gain component or increase the capital loss component of the net gain or loss otherwise recognizable as a consequence of the mergers. - Characterization of Mergers. A merger of a participating partnership into Pioneer USA should be treated for federal income tax purposes as a sale by such partnership of its assets and a distribution of the proceeds in liquidation of the limited partnership interests. Under Section 613A of the Internal Revenue Code, each of the partners must: - maintain the partner's share of the basis in the partnership's oil and gas properties at the partner level; - adjust such basis for depletion deductions; and - use such basis to calculate gain or loss at the partner level on any sale by the partnership of its oil and gas properties. Accordingly, each of the mergers should be generally treated for tax computation purposes as: - a taxable sale by you of your interest in a participating partnership's oil and gas properties for cash and the assumption of liabilities; and - a taxable sale of any remaining partnership assets by the participating partnership followed by a liquidation of the participating partnership. 28 36 - Gain or Loss on Sale of Partnership Oil and Gas Properties. Upon the deemed sale of a partnership's oil and gas properties in the mergers, you will recognize gain or loss equal to the difference between: - the portion of the partnership's "amount realized" on the sale of its oil and gas properties allocated to you; and - your adjusted tax basis in the partnership oil and gas properties sold, which must be reduced to reflect depletion claimed during the current year in respect of production prior to the date of the merger. The amount realized will include the cash received and the amount of any liability assumed by Pioneer USA in connection with the mergers which is attributable to the partnership's oil and gas properties. If gain is recognized on such sale, the portion of the gain that is treated as recapture of intangible drilling and development costs or depletion will be treated as ordinary income. See "Recapture of Intangible Drilling and Development Costs" and "Recapture of Depletion" below. The remainder of such gain generally will constitute "Section 1231 gain." If loss is recognized on such sale, such loss generally will constitute "Section 1231 loss." See "Section 1231 Gains and Losses" below. You must take into account your share of the portion of the gain that constitutes recapture income, if any, as ordinary income and must aggregate your share of the Section 1231 gains and losses along with the Section 1231 gains and losses you realize from other sources. - Other Gain or Loss. You will also recognize your allocable share of the partnership's gain or loss, if any, on the deemed sale of its assets other than oil and gas properties. Such gain or loss will be equal to the difference between the amount realized by the partnership on the sale of such assets and the partnership's adjusted tax basis in such assets. Such gain or loss will be capital or ordinary depending on the nature of the assets sold. Finally, in the event that the cash you receive in the mergers is more or less than the adjusted tax basis in your partnership interests, as adjusted to reflect gains and losses described in the two preceding paragraphs as well as the effects of the partnership's current year activities, then upon the deemed liquidation of a partnership, you will recognize capital gain or loss equal to the difference between such amounts. See "Tax Consequences of Partnership Operations" below. You will be provided with information necessary to make the calculations described above for purposes of filing your own federal income tax return. In order to simplify your federal income tax reporting, this information will include a calculation of the amount and character of your gain on the deemed sale of the partnership's oil and gas properties based upon our estimates. You should verify the accuracy of these calculations based upon your own records. - Section 1231 Gains and Losses. Generally, if the total amount of the Section 1231 gains exceeds the total amount of Section 1231 losses, all such gains and losses will be treated as capital gains and losses, and if the total amount of the Section 1231 losses exceeds the total amount of the gains, all such gains and losses will be treated as ordinary income and losses. However, your net Section 1231 gains will be treated as ordinary income to the extent of your net Section 1231 losses during the immediately preceding five years, reduced by any amount of net Section 1231 losses that have been previously "recaptured" by you pursuant to this rule. - Recapture of Intangible Drilling and Development Costs. Generally, all or a portion of the amounts previously deducted for intangible drilling and development costs with respect to a property must be recaptured upon the disposition of such property by treating the gain, if any, realized on such disposition as ordinary income to the extent of such amounts. With respect to a property placed in service prior to 1987, the potential recapture amount is equal to the excess of the aggregate amounts previously deducted for intangible drilling and development costs with respect to such property over the amount by which the deduction for depletion with respect to such property would have been increased had the intangible drilling and development costs been capitalized and recovered through 29 37 depletion rather than deducted in the year incurred. It should be noted that, if percentage depletion, rather than cost depletion, has been claimed with respect to such property, the hypothetical capitalization of intangible drilling and development costs may result in little or no increase in depletion deductions and, as a consequence, most or all of the intangible drilling and development costs with respect to such property may be subject to recapture. With respect to property placed in service during 1987 or thereafter, the full amount of intangible drilling and development costs previously deducted, unreduced by depletion, is subject to recapture to the extent of any gain. - Recapture of Depletion. Upon the disposition of a property that was placed in service during 1987 or thereafter, all amounts previously deducted for depletion, whether cost depletion or percentage depletion, to the extent such amounts reduced the basis in the property, must be recaptured by treating the gain, if any, recognized on such disposition as ordinary income to the extent of such amounts. No such recapture rule is applicable to a property placed in service before 1987. - Tax Rates. The capital gains rate for individuals and other non-corporate taxpayers is 20% if the capital asset has been held for more than one year at the time of consummation of the mergers. Corporate taxpayers are taxed at a maximum marginal rate of 35% for both capital gains and ordinary income. The maximum marginal federal income tax rate for ordinary income of individuals and other non-corporate taxpayers is 39.6%. Capital losses are deductible only to the extent of capital gains, except that, subject to the passive activity loss limitation discussed below, non-corporate taxpayers may deduct up to $3,000 of capital losses in excess of the amount of their capital gains against ordinary income. Excess capital losses generally can be carried forward to succeeding years. A corporation is permitted to carry back excess capital losses to the three preceding years, provided the carryback does not increase or produce a net operating loss for any of those years. A corporation's carryforward period is five years and a non-corporate taxpayer can carry such losses forward indefinitely. - Passive Activity Loss Limitation. Under Section 469 of the Internal Revenue Code, any losses from the participating partnerships that have been suspended under the passive loss rules will become fully deductible as a result of the mergers. FIRPTA Withholding. Gain recognized by a foreign limited partner on the sale by a partnership of its assets pursuant to the mergers which is effectively connected with the conduct of a U.S. trade or business will be subject to federal income tax. Gain realized on the sale of U.S. real property, including a participating partnership's oil and gas properties, is treated as effectively connected with the conduct of a U.S. trade or business for this purpose. Under Internal Revenue Code Section 1446, a partnership in which an interest is held by a foreign person generally is required to deduct and withhold a tax equal to the highest marginal federal income tax rate applicable to the partner multiplied by such partner's allocable share of effectively connected income. In order to comply with this requirement, each participating partnership will withhold the prescribed percentage of the effectively connected income allocated to you unless you properly complete and sign a "FIRPTA Affidavit" certifying your taxpayer identification number and address, and that you are not a foreign person. Amounts withheld will be creditable against a limited partner's federal income tax liability and, if in excess thereof, a refund may be obtained from the Internal Revenue Service by filing a U.S. income tax return. Tax Consequences of Partnership Operations. The federal income tax consequences of the mergers, described above, are in addition to the tax consequences of your status as a partner in a participating partnership for the taxable year ending on the closing date of the mergers. You must include your allocable share of a participating partnership's items of income, gain, loss, deduction and credit for that taxable year, including your allocable share through the closing date of the mergers, on your federal income tax return for that taxable year. That information will be provided to you on a Schedule K-1 as required by tax laws. The results of partnership operations for such period will impact your tax basis in a participating partnership, and your computation of gain or loss resulting from the mergers. 30 38 ACCOUNTING TREATMENT The mergers will be accounted for as purchases under generally accepted accounting principles. Under those rules, Pioneer USA will record the assets and liabilities of the participating partnerships on its books at their estimated fair market values. NO APPRAISAL OR DISSENTER RIGHTS Under the laws of the State of Delaware and the State of Texas, which are the states of formation of the partnerships, you are not entitled to appraisal or dissenter rights with respect to the mergers. FUTURE OF NONPARTICIPATING PARTNERSHIPS If the limited partners of a partnership do not approve the merger of that partnership, it will not participate in the mergers and will remain in existence. Each nonparticipating partnership will continue to operate as a separate legal entity with its own assets and liabilities. There will be no immediate change in its business objectives, and Pioneer USA plans to continue to manage and operate each nonparticipating partnership in accordance with the terms of its current partnership agreement. A limited partner in a nonparticipating partnership will retain the rights, privileges and obligations that the partner currently has pursuant to the partnership agreement of the nonparticipating partnership. At the same time that Pioneer USA mails checks to the partners of participating partnerships in payment of the merger values, Pioneer USA will mail any cash distributions that were delayed for administrative purposes prior to the completion of the mergers to the partners of nonparticipating partnerships. Pioneer USA's board of directors will determine each nonparticipating partnership's business plan. In addition, the board of directors of each of Pioneer and Pioneer USA will decide what, if any, actions they will take with respect to the nonparticipating partnerships. Potential activities include a tender offer for partnership interests of limited partners or a proposal to acquire the assets of, or merge with, one or more of the nonparticipating partnerships. Such proposals may be on terms similar to or different from those of the mergers described in this document. Pioneer USA plans to continue to manage each nonparticipating partnership until such partnership is dissolved or Pioneer USA is replaced as the general partner of such partnership. The replacement of Pioneer USA as general partner would require compliance with the partnership agreement of such nonparticipating partnership, including the requisite vote of the limited partners thereof. A nonparticipating partnership may be dissolved in the future in accordance with its partnership agreement if Pioneer USA or any substituted general partner withdraws from the nonparticipating partnership, or in some cases, otherwise elects to dissolve that partnership. Pioneer USA might withdraw from, or otherwise elect to dissolve, a nonparticipating partnership if Pioneer USA determines that the nonparticipating partnership's continued operation is uneconomical or its dissolution and liquidation are in the best interests of the partners. Upon dissolution, the nonparticipating partnership's assets may be sold for cash or securities, which may be more or less than the merger value assigned to that partnership, or distributed in kind to the partners of the nonparticipating partnership. Any such sale may be to Pioneer or an affiliate of Pioneer and may involve cash or securities of Pioneer. NONMANAGING GENERAL PARTNERS OF CERTAIN PARTNERSHIPS Five of the partnerships described in this document have two general partners. In those five partnerships, Pioneer USA is the managing general partner. The second general partner in those partnerships is a parallel partnership whose limited partners are former affiliates of Pioneer's predecessors. 31 39 The names of the five partnerships and the names of the nonmanaging general partner in each of those partnerships are: PARTNERSHIP NONMANAGING GENERAL PARTNER ----------- --------------------------- Parker & Parsley 82-I, Ltd. Parker & Parsley Employees 82-I, Ltd. Parker & Parsley 82-II, Ltd. Parker & Parsley Employees 82-II, Ltd. Parker & Parsley 83-A, Ltd. Parker & Parsley Employees 83-A, Ltd. Parker & Parsley 83-B, Ltd. Parker & Parsley Employees 83-B, Ltd. Parker & Parsley 84-A, Ltd. Parker & Parsley Employees 84-A, Ltd. Pioneer USA is the sole general partner of each of the nonmanaging general partners. In that capacity, Pioneer USA has authority: - to cause the nonmanaging general partner to perform its obligations relating to the partnership described above; and - to exercise on behalf of the nonmanaging general partner all of the rights and elections granted to the nonmanaging general partner by the partnership described above. Pioneer USA, as the general partner of the nonmanaging general partners, has approved the mergers and the distribution of this document to the limited partners. Pioneer USA will not receive any cash payment in the mergers for its partnership interests in the nonmanaging general partners. THIRD-PARTY OFFERS Pioneer USA will consider offers from third parties to purchase any partnership or its assets. Those who wish to make an offer for any partnership or its assets must demonstrate to Pioneer USA's reasonable satisfaction their financial ability and willingness to complete such a transaction. Before reviewing non-public information about a partnership, a third party will need to enter into a customary confidentiality agreement. Pioneer USA will also disclose the price at which Pioneer plans to acquire the non-public and employee partnerships. Offers should be at prices and on terms that are fair to the partners of the partnership and more favorable to the limited partners than the prices and terms proposed for the mergers in this document. Pioneer reserves the right to match or top any such offer. Persons desiring to make an offer for any partnership should contact Timothy L. Dove or Mark L. Withrow, Board of Directors, Pioneer Natural Resources USA, Inc., 1400 Williams Square West, 5205 North O'Connor Boulevard, Irving, Texas 75039 by November 1, 1999. At the same time as this transaction, Pioneer is also offering to acquire 21 non-public limited partnerships and 13 privately-held employee limited partnerships through mergers of those partnerships into Pioneer USA. See "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document. Pioneer USA will also consider offers from third parties to purchase any of those partnerships as described in the preceding paragraph. MERGER AMENDMENT In order to complete the mergers, the partnership agreements require an amendment to add a provision permitting the mergers of the partnerships with and into Pioneer USA. See the merger proposals, which include the merger amendment, set forth in Appendix D to this document. At the special meetings, the limited partners will vote upon the merger amendment, which, if approved, will be effective immediately prior to the effectiveness of the mergers. 32 40 TERMINATION OF REGISTRATION AND REPORTING REQUIREMENTS As a result of the mergers, the partnership interests in the participating partnerships, as well as the participating partnerships themselves, will cease to exist. Consequently, Pioneer USA intends to terminate: - registration of the partnership interests of the participating partnerships under the Securities Exchange Act of 1934; and - the participating partnerships' obligations to file reports and other information under the Securities Exchange Act of 1934. Pioneer USA plans to cause any nonparticipating partnerships to continue to file reports and other information under the Securities Exchange Act of 1934. However, Pioneer USA's board of directors could determine to cause such partnerships to terminate their reporting obligations as permitted by federal securities laws. SOURCE OF FUNDS Pioneer USA will need approximately $64.8 million in cash to complete the mergers for all of the partnerships, including the 21 non-public limited partnerships and the 13 privately-held employee partnerships. Pioneer USA will borrow that amount from Pioneer as an intercompany loan. Pioneer USA plans to repay that intercompany loan with cash flows from operations. Immediately after completion of the mergers, the cash portion of the working capital in each partnership that Pioneer acquires will be used to repay a portion of the intercompany loan. Pioneer, in turn, will obtain such funds from its amended credit facility agreement with a syndicate of banks, including Bank of America, N.A., formerly NationsBank of Texas, N.A. As of June 30, 1999, the outstanding balance due under Pioneer's credit facility was $1.01 billion, excluding outstanding, undrawn letters of credit of $19 million, and the borrowing capacity available under Pioneer's credit facility was $178 million. Under the terms of its credit facility, Pioneer must reduce its outstanding credit facility borrowings to $941 million prior to December 31, 1999. Such borrowings bear interest, at Pioneer's option, based on: - the prime rate of Bank of America, N.A., formerly NationsBank of Texas, N.A., which was 7.75% at June 30, 1999; - a eurodollar rate, which is substantially equal to the London Interbank Offered Rate, or LIBOR, adjusted for the reserve requirement as determined by the Board of Governors of the Federal Reserve System with respect to transactions in eurocurrency liabilities; or - a competitive bid rate as quoted by the lending banks electing to participate pursuant to Pioneer's request. LIBOR rate borrowings under Pioneer's credit facility have periodic maturities, at Pioneer's option, of one, two, three, six, nine or 12 months. Bid rate borrowings have periodic maturities, at Pioneer's option, of not less than 15 days nor more than 360 days. The annual interest rate on LIBOR rate borrowings varies with the periodic LIBOR rate and with specified interest rate margins that are based on Pioneer's senior, unsecured long-term debt ratings and certain leverage ratios. The maximum interest rate margin on LIBOR rate borrowings is 300 basis points. Pioneer's obligations under its credit facility are guaranteed by Pioneer USA and certain other United States subsidiaries of Pioneer, and are secured by a pledge of a portion of the capital stock of certain non-United States subsidiaries of Pioneer. The terms of Pioneer's credit facility also contain various restrictive covenants and compliance requirements, which include: - limits on the incurrence of additional indebtedness; - restrictions as to merger, sale or transfer of assets without the banks' prior consent; 33 41 - enhancement of the banks' collateral rights under certain circumstances; and - the maintenance of certain leverage ratios. The most restrictive leverage ratio is the maintenance of a ratio of outstanding Pioneer senior debt to earnings before interest, depletion, amortization, income taxes, exploration and abandonment and other non-cash expenses not to exceed 5.75 to one through September 30, 1999, 4.25 to one through March 31, 2000, and 3.5 to one after that date. PAYMENT OF EXPENSES AND FEES The partnerships, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document, which participate in the mergers, will pay all estimated expenses and fees of the mergers. The net working capital component of each partnership's merger value has been reduced by that partnership's pro rata share, based on its reserve value, of the estimated expenses and fees. If Pioneer terminates the merger as to any partnership or if any partnership does not approve its merger, then Pioneer will pay the expenses allocated to that partnership. Pioneer estimates that the expenses and fees for all of the mergers will be as follows: Filing fee with SEC......................................... $ 9,500 Legal fees.................................................. 400,000 Accounting fees............................................. 30,000 Financial advisor fees...................................... 200,000 Independent petroleum consultant fees....................... 60,000 Printing and mailing fees................................... 3,770,000 Information agent fees and solicitation and tabulation expenses.................................................. 130,000 Miscellaneous............................................... 20,000 ---------- Total expenses.................................... $4,619,500 ========== 34 42 THE MERGER AGREEMENT The following describes the material terms of the merger agreement. Pioneer and Pioneer USA expect to sign the merger agreement after the September 30, 1999 merger values are determined. The full text of the form of the merger agreement is attached as Appendix E to this document and is incorporated by reference in this document. We encourage you to read the entire merger agreement. STRUCTURE; EFFECTIVE TIME The merger agreement provides for the mergers of the participating partnerships with and into Pioneer USA, with Pioneer USA surviving the mergers. The mergers will become effective at the time of the filing of certificates of merger for each participating partnership with the Secretary of State of the State of Delaware and, for each participating partnership formed in Texas, with the Secretary of State of the State of Texas. The certificates of merger are expected to be filed as soon as practicable after the last condition precedent to the mergers set forth in the merger agreement has been satisfied or waived. We estimate that the closing of the mergers will be in the latter half of December 1999. EFFECTS OF THE MERGERS As a result of the mergers, the partners in the participating partnerships will have no continuing interest in those partnerships. Following the mergers, there will be no trading market for the partnership interests in, and no further distributions paid to the former partners of, the participating partnerships. In addition, following the consummation of the mergers, the registration of any partnership interests in participating partnerships under the Securities Exchange Act of 1934 will be terminated. CONDUCT OF BUSINESS PRIOR TO THE MERGERS From the date of the merger agreement until the effective time of the mergers, Pioneer, Pioneer USA and the partnerships are required: - to conduct their businesses only in the ordinary course consistent with past practice; and - to use their reasonable best efforts: - to preserve intact their business organizations; - to keep available the services of their officers, employees and consultants; and - to preserve their relationships with customers, suppliers and other persons with which they have significant business dealings. Pioneer USA has suspended cash distributions to partners until after the effective time of the mergers. Partners of nonparticipating partnerships will receive cash distributions that are delayed for administrative purposes at the same time Pioneer USA mails checks to the partners of participating partnerships in payment of merger values. OTHER AGREEMENTS Special Meetings; Proxies. Pioneer USA has agreed to cause the special meetings of the limited partners to be duly called and held as soon as reasonably practicable for the purpose of voting on the approval and adoption of the merger proposals. Pioneer USA has also agreed to use its reasonable best efforts to solicit from the limited partners proxies in favor of the merger proposals and to take all other action necessary or advisable to secure any vote or consent of the limited partners required by the partnership agreements or the merger agreement or by law in connection with the mergers. Reasonable Commercial Efforts.

The purpose of the special meetings, and any adjournment or postponement of the special meetings, is for the limited partners of each partnership to consider and vote on the following matters: - A proposal to approve an Agreement and Plan of Merger dated as of , 1999, among Pioneer, Pioneer USA and each of the partnerships. Each partnership that approves this proposal will merge with and into Pioneer USA, with Pioneer USA surviving the merger. Each partnership interest of a participating partnership, other than Pioneer USA's interests, will be converted into the right to receive an amount of cash. The amount of cash to be paid for all partnership interests of a participating partnership will be based on the participating partnership's merger value. The merger value of a participating partnership is equal to its reserve value and its net working capital, as reduced by its pro rata share of the estimated expenses and fees of the mergers of all of the partnerships, in each case as of September 30, 1999. We calculated the cash payment using information as of June 30, 1999 for purposes of illustration. We intend to change each reference to "June 30, 1999" to be "September 30, 1999" and to revise June 30, 1999 numbers as of September 30, 1999 before mailing the definitive proxy statement to the limited partners. The cash payment will be allocated among the partners based on the liquidation provisions of each partnership agreement. Pioneer USA will not receive any cash payment for its partnership interests in the participating partnerships. However, as a result of the mergers, Pioneer USA will acquire 100% of the properties of the participating partnerships, including properties attributable to its partnership interests in those partnerships. - A proposal to amend the partnership agreement of each partnership to permit the partnership's merger with Pioneer USA. If the amendment is not approved, that partnership cannot merge into Pioneer USA even if the partners of that partnership approve the merger agreement. - A proposal to approve the opinion issued to Pioneer USA by on behalf of the limited partners that neither the grant nor the exercise of the right to approve the mergers by the limited partners will result in the loss of any limited partner's limited liability or adversely affect the tax status of the partnerships and to approve the selection of as special legal counsel for the limited partners to render such legal opinion. - Other business that properly comes before the special meetings or any adjournments or postponements of the special meetings. Pioneer USA is not aware of any other business for the special meetings. The Delaware Revised Uniform Limited Partnership Act and the Texas Revised Limited Partnership Act require limited partner approval and adoption of the merger agreement and the merger amendment. Generally, the partnership agreements of the partnerships require that special legal counsel for the limited partners render its legal opinion related to the limited partners' approval of the mergers. See "The Mergers -- Legal Opinion for Limited Partners" on page 27 of this document. PIONEER USA'S BOARD OF DIRECTORS UNANIMOUSLY DETERMINED THAT THE MERGERS ARE ADVISABLE, FAIR TO THE LIMITED PARTNERS OF EACH PARTNERSHIP, AND IN THE LIMITED PARTNERS' BEST INTERESTS. THE BOARD RECOMMENDS THAT THE LIMITED PARTNERS VOTE FOR THE MERGER PROPOSALS. ALTHOUGH PIONEER USA'S BOARD OF DIRECTORS HAS ATTEMPTED TO FULFILL ITS FIDUCIARY DUTIES TO THE LIMITED PARTNERS, PIONEER USA'S BOARD OF DIRECTORS HAD CONFLICTING INTERESTS IN EVALUATING THE MERGERS BECAUSE EACH MEMBER OF ITS BOARD OF DIRECTORS IS ALSO AN OFFICER OF PIONEER. One or more representatives of Ernst & Young LLP are expected to be present at the special meetings to answer appropriate questions of limited partners and to make a statement if so desired. 39 47 RECORD DATE; VOTING RIGHTS AND PROXIES Only limited partners of record at the close of business on , 1999 are entitled to notice of and to vote at the special meetings of the partnerships in which they own partnership interests, or any adjournments or postponements of such special meetings. Pioneer USA and its affiliates are entitled to vote partnership interests they hold as limited partners in all of the partnerships except: Parker & Parsley 85-A, Ltd. Parker & Parsley 85-B, Ltd. Parker & Parsley 91-A, L.P. Parker & Parsley 91-B, L.P. Limited partners of record are entitled to vote at their partnership's special meeting based on their percentage of partnership interests in that partnership. Each limited partner will receive a proxy card for each partnership in which that limited partner holds partnership interests. The proxy card will indicate the amount of the cash payment offered with respect to such partnership interests in each partnership. The amount of the cash payment offered as shown on the proxy card will not be adjusted. The percentage of partnership interests that a limited partner holds in a partnership is determined by comparing the amount of the limited partner's initial investment, including any additional assessments, in the partnership to the total investment of all partners, including any additional assessments, in the partnership. The aggregate initial investment, including any additional assessments, in each of the partnerships by the limited partners is set forth in Table 1 of Appendix A. A limited partner of record may grant a proxy to vote for or against, or may abstain from voting on, the merger proposals applicable to each of the partnerships in which he holds partnership interests. To be effective for purposes of granting a proxy to vote on the merger proposals applicable to each partnership, a proxy card must be properly completed, executed and delivered to Pioneer USA before the special meetings. All partnership interests represented by properly executed proxies will, unless these proxies have been previously revoked, be voted in accordance with the instructions indicated in these proxies. If no instructions are indicated, the partnership interests will be voted for approval and adoption of the merger proposals. A properly executed proxy card marked abstain is counted as present for purposes of determining the presence or absence of a quorum at the special meetings, but will not be voted. Accordingly, abstentions will have the same effect as a vote against the merger proposals. Unrevoked proxies granted in the proxy cards will be voted at the special meetings or at any adjournment or postponement thereof, if received by Pioneer USA before the special meetings. Proxies granted in the proxy cards will remain valid until the completion of the special meetings. The partnership agreements require that a meeting be held within 60 days of the date of mailing of the notice of meeting. The partnership agreements do not specifically address, and Pioneer USA has not sought any opinions of counsel as to, whether proxies may be voted at a meeting originally scheduled to be held within 60 days of the sending of the notice and adjourned or postponed to a date more than 60 days after the date of notice. Pioneer USA will not accept a vote of the limited partners in such circumstances unless it receives an opinion of counsel that such a vote would be valid. Votes cast by proxy or in person at the special meetings will be tabulated by the inspector of election appointed for the meetings. Pioneer USA does not know of any matters other than the approval of the merger proposals that are to come before the special meetings. If any other matter or matters are properly presented for action at the special meetings, the persons named in the enclosed form of proxy and acting under the proxy will have the discretion to vote on those matters in accordance with their best judgment. 40 48 You may revoke a proxy you have given at any time before that proxy is voted at the special meetings by: - giving written notice of revocation to Pioneer USA; - signing and returning a later dated proxy; or - voting in person at the special meetings. Your notice of revocation will not be effective until Pioneer USA receives it at or before the special meetings. Your presence at the special meetings will not automatically revoke your proxy in a proxy card. Revocation during the special meetings will not affect votes previously taken. You may deliver your written notice of revocation in person or by mail, telegraph, telex, or facsimile. Any written notice of revocation must specify your name and limited partner number as shown on your proxy card and the name of the partnership to which your revocation relates. SOLICITATION OF PROXIES We are soliciting your proxy pursuant to this document. The net working capital component of the merger value of each partnership, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document, has been reduced by the partnership's pro rata share, based on its reserve value, of all estimated expenses and fees for the mergers of all of the partnerships, including the expenses and fees described below. Pioneer USA has retained to assist in the solicitation of proxies from the limited partners of the partnerships. The total fees and expenses of are estimated to aggregate $ . In addition to solicitation by use of the mail, proxies may be solicited by , by other outside contractors and by directors, officers and employees of Pioneer USA and Pioneer in person or by telephone, telegram or other means of communication. The total fees and expenses of any outside contractors which may be retained to solicit proxies are estimated to aggregate $ . The directors, officers and employees will not be additionally compensated, but may be reimbursed for out-of-pocket expenses incurred in connection with the solicitation. Arrangements may also be made with other brokerage firms, banks, custodians, nominees and fiduciaries for the forwarding of proxy solicitation materials to owners of limited partnership interests held of record by those persons. The partnerships, including the 21 non-public limited partnerships and 13 privately-held employee partnerships described in "Transactions Among The Partnerships, Pioneer, Pioneer USA and Their Directors and Officers" on page 45 of this document, will pay their pro rata share, based on their reserve values, of those persons' reasonable expenses incurred in forwarding those materials. Pioneer USA has also retained to act as information agent to perform consulting, administration and clerical work with respect to the mergers. Pioneer USA has agreed to indemnify against certain liabilities, including liabilities under the federal securities laws. will also be responsible for receipt and tabulation of the proxy cards. The fees and expenses of for its services as information agent and tabulator are included in the aggregate amount set forth above. We intend to mail checks to the partners of record promptly after completing the mergers. Certificates representing partnership interests will be automatically cancelled, and you will not have to surrender your certificates to receive the cash payment. QUORUM The presence in person or by properly executed proxy of a majority of limited partnership interests entitled to vote in each partnership is necessary to constitute a quorum at that partnership's special meeting. 41 49 If a quorum is not present at any special meeting, the limited partners entitled to vote who are present or represented by proxy at that special meeting may adjourn or postpone that special meeting without notice until a quorum is present. If a quorum is present at the adjourned or postponed meeting, any business may be transacted that may have been transacted at the special meeting had a quorum originally been present. If the adjournment or postponement is for more than 30 days or if after the adjournment or postponement a new record date is fixed for the adjourned or postponed meeting, a notice of the adjourned or postponed meeting shall be given to each limited partner of record entitled to vote at the adjourned or postponed meeting. The persons named as proxies intend to vote in favor of any motion to adjourn or postpone the special meetings if, prior to the special meetings, they have not received sufficient proxies to approve the mergers described in this document. This process will be repeated at any adjourned or postponed meeting until sufficient proxies to vote in favor of the mergers have been received or it appears that sufficient proxies will not be received. REQUIRED VOTE; BROKER NON-VOTES Approval of the merger proposals requires the affirmative vote of the limited partners holding a majority of limited partnership interests in that partnership. Pioneer USA and its affiliates are entitled to vote their partnership interests on the merger proposals for all of the partnerships except as set forth above under "The Special Meetings -- Record Date; Voting Rights and Proxies" on page 40. Brokers, if any, who hold partnership interests in street name for customers have the authority to vote on certain "routine" proposals when they have not received instructions from beneficial owners. However, these brokers are precluded from exercising their voting discretion with respect to the approval and adoption of non-routine matters such as the merger proposals and, thus, absent specific instructions from the beneficial owner of the partnership interests, brokers are not empowered to vote the partnership interests with respect to the merger proposals. These "broker non-votes" will have the effect of a vote against the merger proposals. PARTICIPATION BY ASSIGNEES Pioneer USA has the discretionary authority granted to it under the partnership agreements to withhold its consent to the substitution of any assignees as partners. To facilitate the notification given to limited partners about the mergers, Pioneer USA intends to exercise that authority and withhold its consent to the substitution of any assignees as partners from September 8, 1999 until the closing date of the mergers, but in no event later than January 31, 2000. SPECIAL REQUIREMENTS FOR CERTAIN LIMITED PARTNERS Pioneer USA may require that any proxy card executed by an entity, such as a trust, corporation, or partnership, be accompanied by evidence or an opinion of counsel that such entity: - has met all requirements of its governing instruments; and - is authorized to execute and deliver the proxy card under the laws of the jurisdiction under which the entity was organized. Pioneer USA will require the named trustee and the beneficial owner of trusts, including individual retirement accounts, to execute the proxy card. In some cases, Pioneer USA may provide a limited partner with an envelope, pre-addressed to his individual retirement account trustee, so that the limited partner may forward his executed proxy card to the trustee for the trustee's signature and subsequent delivery to Pioneer USA. Delivery of a proxy card to the trustee, with or without the use of a pre-addressed envelope, and delivery of a proxy card from the trustee to Pioneer USA are at the risk of the limited partner. 42 50 VALIDITY OF PROXY CARDS A proxy card will not be valid unless it has been properly completed and executed and timely delivered to Pioneer USA's information agent with all other required documents. Pioneer USA will determine all questions as to the validity, form, eligibility, time of receipt and acceptance of a proxy card and its determination will be final and binding. Pioneer USA's interpretation of the terms and conditions of the mergers, including the instructions for the proxy card, will also be final and binding. A proxy card will not be valid until any irregularities have been cured or waived. If Pioneer USA does not waive the irregularities, it will return the defective proxy card to the limited partner as soon as practicable. Pioneer USA is under no duty to give notification of defects in a proxy card and will incur no liability if it fails to give such notification. Delivery of a proxy card is at the risk of the limited partner. A proxy card will be effective for purposes of voting only when it is actually received by Pioneer USA's information agent. To ensure receipt of the proxy card and all other required documents, we suggest that limited partners use overnight courier delivery or certified or registered mail, return receipt requested. LOCAL LAWS Proxy solicitations will not be made to, nor will proxy cards be accepted from, limited partners in any jurisdiction in which the solicitations would not be in compliance with federal and state securities or other laws. INTERESTS OF PIONEER, PIONEER USA AND THEIR DIRECTORS AND OFFICERS A number of conflicts of interest are inherent in the relationships among the partnerships, Pioneer USA, Pioneer and their respective directors and officers. CONFLICTING DUTIES OF PIONEER USA, INDIVIDUALLY AND AS GENERAL PARTNER Pioneer USA, as general partner of the partnerships, has a duty to manage the partnerships in the best interests of the limited partners. Pioneer USA also has a duty to operate its business for the benefit of its sole stockholder, Pioneer. Consequently, Pioneer USA's duties to the limited partners may conflict with its duties to Pioneer. The members of the board of directors of Pioneer USA have a duty to cause Pioneer USA to manage the partnerships in the best interests of the limited partners. All members of the board of directors of Pioneer USA are officers of Pioneer and Pioneer USA. Thus, the members of the board of directors of Pioneer USA have duties to operate Pioneer USA's business for the benefit of its sole stockholder, Pioneer, and, as officers of Pioneer, to operate Pioneer's business in its best interests. Consequently, the duties of the members of the board of directors of Pioneer USA to the limited partners may conflict with the duties of those members to Pioneer, Pioneer USA and their stockholders. PIONEER USA'S EMPLOYEES PROVIDE SERVICES TO THE PARTNERSHIPS The partnerships currently have no employees. Each partnership relies on Pioneer USA's personnel. Pioneer USA provides all management functions on behalf of the partnerships. Therefore, each partnership currently competes with Pioneer USA for the time and resources of Pioneer USA's employees. FINANCIAL INTERESTS OF OFFICERS AND DIRECTORS IN PIONEER The officers and directors of Pioneer USA and Pioneer have equity interests in Pioneer through stock ownership, stock options and other stock-based compensation, but do not have financial or equity interests in the partnerships. The boards of directors of Pioneer and Pioneer USA believe that any economic benefit 43 51 their directors may obtain from the mergers will be modest and will not result in a material economic benefit to their directors individually. FINANCIAL INTERESTS OF OFFICERS AND DIRECTORS IN PARTNERSHIPS The officers and directors of Pioneer USA and Pioneer have no financial or equity interests in the partnerships described in this document. See "Ownership of Partnership Interests" on page 44. Scott D. Sheffield, Chairman of the Board, President and Chief Executive Officer of Pioneer and President of Pioneer USA, and Mark L. Withrow, Executive Vice President, General Counsel and Secretary of each of Pioneer and Pioneer USA, own partnership interests in some of the 13 privately-held employee partnerships that Pioneer is offering to acquire at the same time it acquires the partnerships described in this document. INDIVIDUAL PARTNERSHIP'S PERSPECTIVE NOT CONSIDERED IN MERGERS Pioneer USA serves as the managing or sole general partner for all of the partnerships and did not view the mergers solely from the perspective of a single partnership. Each partnership is governed by its own partnership agreement, the terms of which may or may not be similar to the terms of the partnership agreements of the other partnerships. Consequently, in determining the terms and conditions of the mergers, Pioneer USA may have advocated positions which would be in the best interest of one of the partnerships at the expense of another. If each of the partnerships had separate general partners, these general partners would have had totally independent perspectives, not affected by a consideration of the interests of any of the other partnerships, which may have led them to advocate positions during the structuring of the mergers different than those taken by Pioneer USA. THE PARTNERSHIPS PAY OPERATOR FEES TO PIONEER USA Pioneer USA operates most of the partnerships' wells. Each partnership has entered into one or more standard industry operating agreements with Pioneer USA. Those operating agreements establish the base fee paid by the partnership to Pioneer USA for its lease operating services. That base fee increases annually based on a rate established by the Counsel of Petroleum Accountants Society, or COPAS, for the oil and gas industry. OWNERSHIP OF PARTNERSHIP INTERESTS Pioneer does not directly own any partnership interests in the partnerships. Pioneer beneficially owns all of Pioneer USA's partnership interests in the partnerships. Table 6 of Appendix A to this document contains the voting percentage as of August 1, 1999, of the outstanding partnership interests for each partnership that are beneficially owned by Pioneer USA as a limited partner. As of August 1, 1999, no person or entity known by Pioneer USA beneficially owns more than 5% of the outstanding partnership interests in any partnership, except in Parker & Parsley 82-I, Ltd. There, Pioneer USA repurchased partnership interests equal to $1,188,500, representing a 10.07% beneficial ownership of the partnership interests in that partnership. Pioneer USA has sole investment and voting power with respect to partnership interests it beneficially owns. Except as set forth above, none of Pioneer, Pioneer USA, or, to the knowledge of Pioneer USA, any of their directors or executive officers, or any associate or subsidiary of Pioneer, Pioneer USA or any such director or officer: - beneficially owns any partnership interests of the partnerships; or - has effected any transactions in any partnership interests of the partnerships during the past 60 days. 44 52 As of the record date for the special meetings, Scott D. Sheffield, Chairman of the Board, President and Chief Executive Officer of Pioneer and President of Pioneer USA, owned, on average, approximately 6% of the outstanding limited partnership interests in each of 11 of the 13 privately-held employee partnerships that are being acquired by Pioneer at the same time as the partnerships described in this document. As of the record date for the special meetings, Mark L. Withrow, Executive Vice President, General Counsel and Secretary of each of Pioneer and Pioneer USA, owned, on average, approximately 5% of the outstanding limited partnership interests in each of two of those 13 privately-held employee partnerships. TRANSACTIONS AMONG THE PARTNERSHIPS, PIONEER, PIONEER USA AND THEIR DIRECTORS AND OFFICERS Except as described in this document, there have not been any contacts, transactions or negotiations between Pioneer, Pioneer USA, any of their respective subsidiaries, or, to the knowledge of Pioneer and Pioneer USA, any director or executive officer of Pioneer or Pioneer USA, on the one hand, and the partnerships or any of their general partners, including Pioneer USA, directors, officers or affiliates, on the other hand, that are required to be disclosed pursuant to the rules and regulations of the SEC. Except as described in this document, none of Pioneer, Pioneer USA, or, to the knowledge of Pioneer and Pioneer USA, any director or executive officer of Pioneer or Pioneer USA, has any contract, arrangement, understanding or relationship with any person with respect to any securities of the partnerships. At the same time as this transaction, Pioneer is also offering to acquire 21 non-public limited partnerships and 13 privately-held employee limited partnerships through mergers of those partnerships into Pioneer USA. Those additional limited partnerships are drilling partnerships like the drilling partnerships described in this document, but the additional limited partnerships do not have reporting obligations under the Securities Exchange Act of 1934. The limited partners of the 13 employee limited partnerships are current and former affiliates of Pioneer and its predecessors. Pioneer USA is the managing or sole general partner of those additional limited partnerships. The terms of the mergers, including the method of establishing the merger values and cash payment amounts for the limited partners in those partnerships, are the same as are set forth for the reporting partnerships in this document. If you approve the mergers, there are various ways that Pioneer USA may use the properties. Pioneer USA may continue to operate the properties, it may sell the properties to third parties, including a royalty trust, or it may spin-off the properties to its stockholders. Although Pioneer USA plans to operate the properties in the immediate future following completion of the mergers, it has not decided how to use the properties in the long-term. 45 53 MANAGEMENT PIONEER The following information sets forth the age, business experience during the past five years, positions and offices with Pioneer, and periods of service of each director and executive officer of Pioneer.

This information should not be relied upon as any indication of the price at which the partnership interests may trade. There may have been other secondary sale transactions in the partnership interests, although no information regarding any such transactions is available to Pioneer USA. Because the information regarding sale transactions in the partnership interests in this table is provided without verification by Pioneer USA and because the information provided does not reflect sufficient activity to cause the prices shown to be representative of the market values of the partnership interests, the information should not be relied upon as indicative of the ability of limited partners to sell their partnership interests in secondary sale transactions or as to the prices at which the partnership interests may be sold. A-15 76 APPENDIX B SUMMARY RESERVE REPORT OF WILLIAMSON PETROLEUM CONSULTANTS, INC. FOR THE PARTNERSHIPS September 3, 1999 Pioneer Natural Resources USA, Inc. 5205 North O'Connor Boulevard, Suite 1400 Irving, Texas 75039 Attention Board of Directors Gentlemen: Subject: Letter Report Including 25 Reports Prepared by Williamson Petroleum Consultants, Inc. for Pioneer Natural Resources USA, Inc. to the Interests of Limited Partners or the Converted Limited Partners in Various Parker & Parsley Partnerships Managed by Pioneer Natural Resources USA, Inc. Effective December 31, 1998 for Disclosure to the Securities and Exchange Commission Williamson Project 9.8740 In accordance with your request, Williamson Petroleum Consultants, Inc. (Williamson) has prepared this summary letter for inclusion in the proxy statement to be distributed to the limited partners of the referenced partnerships by Pioneer Natural Resources USA, Inc. (Pioneer USA). This letter includes 25 Williamson reports prepared for Pioneer USA to the interests of the limited partners or the converted limited partners in various Parker & Parsley partnerships managed by Pioneer USA effective December 31, 1998 for disclosure to the Securities and Exchange Commission (SEC). A listing of the 25 Williamson reports is included as Exhibit I. I. ESTIMATED RESERVES AND ESTIMATED FUTURE NET REVENUES The total Williamson estimated net proved reserves that are attributable to the evaluated interests of the 25 partnership reports are shown in Exhibit II and were based on economic parameters and operating condition considered applicable as of December 31, 1998 and may be used in disclosure to the SEC. The present values of the estimated future net revenues from proved reserves were calculated using a discount rate of 10.00 percent per annum and were computed in accordance with the financial reporting requirements of the SEC and are presented in Exhibit II. At the request of Pioneer USA, Williamson used the Landmark graphics and reserves and economics evaluation software, Aries, to prepare this summary report. In evaluations of these properties prior to December 31, 1991, Williamson utilized its proprietary software programs. No comparative tests have been performed to determine the difference in evaluation results of either reserves or revenue quantities that may occur solely as a result of the differences in the programs nor has Williamson performed tests to determine the accuracy of Aries. However, in accordance with the request made by Pioneer USA and the general acceptance of Aries by the oil and gas industry, Williamson has used Aries to prepare this report. B-1 77 Pioneer Natural Resources USA, Inc. Board of Directors September 3, 1999 Page 2 II. DEFINITIONS OF SEC RESERVES(1) The estimated reserves presented in this summary letter are net proved reserves, including proved developed producing, proved developed nonproducing, and proved undeveloped reserves, and were computed in accordance with the financial reporting requirements of the SEC. In preparing these evaluations, no attempt has been made to quantify the element of uncertainty associated with any category. Reserves were assigned to each category as warranted. The definitions of oil and gas reserves pursuant to the requirements of the Securities Exchange Act are: Proved Reserves(2) Proved reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under the economic criteria employed and existing operating conditions, i.e., prices and costs as of the date the estimate is made. Prices and costs include consideration of changes provided only by contractual arrangements but not on escalations based upon an estimate of future conditions. A. Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation test. The area of a reservoir considered proved includes: 1. that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any; and 2. the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir. B. Reserves which can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the "proved' classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based. C. Estimates of proved reserves do not include the following: 1. oil that may become available from known reservoirs but is classified separately as "indicated additional reserves"; 2. crude oil, natural gas, and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors; 3. crude oil, natural gas, and natural gas liquids, that may occur in undrilled prospects; and 4. crude oil, natural gas, and natural gas liquids, that may be recovered from oil shales, coal(3), gilsonite, and other such sources. - --------------- (1 )For evaluations prepared for disclosure to the Securities and Exchange Commission, see SEC Accounting Rules. Commerce Clearing House, Inc. October 1981, Paragraph 290, Regulation 210.4-10, p. 329. (2) Any variations to these definitions will be clearly stated in the report. (3) According to Staff Accounting Bulletin 85, excluding certain coalbed methane gas. B-2 78 Pioneer Natural Resources USA, Inc. Board of Directors September 3, 1999 Page 3 Proved Developed Reserves(4) Proved developed reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery should be included as "proved developed reserves" only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved. Proved Undeveloped Reserves Proved undeveloped reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage shall be limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances should estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir. III. DISCUSSION OF SEC RESERVES The properties evaluated in this report are located in the state of Texas with the majority of the value in the Spraberry (Trend Area) field. The individual projections of lease reserves and economics prepared to produce this summary report include data that describe the production forecasts and associated evaluation parameters such as interests, taxes, product prices, operating costs, investments, salvage values, abandonment costs, and net profit interests. Net income to the evaluated interests is the future net revenue after consideration of royalty revenue payable to others, taxes, operating expenses, investments, salvage values, abandonment costs, and net profit interests, as applicable. The future net revenue is before federal income tax and excludes consideration of any encumbrances against the properties if such exist. The future net revenue values presented in this report were based on projections of oil and gas production. It was assumed there would be no significant delay between the date of oil and gas production and the receipt of the associated revenue for this production. No opinion is expressed by Williamson in this report as to a fair market value of the evaluated properties. Unless specifically identified and documented by Pioneer USA as having curtailment problems, gas production trends have been assumed to be a function of well productivity and not of market conditions. The effect of "take or pay" clauses in gas contracts was not considered. - --------------- (4) Williamson Petroleum Consultants, Inc. separates proved developed reserves into proved developed producing and proved developed nonproducing reserves. This is to identify proved developed producing reserves as those to be recovered from actively producing wells; proved developed nonproducing reserves as those to be recovered from wells or intervals within wells, which are completed but shut in waiting on equipment or pipeline connections, or wells where a relatively minor expenditure is required for recompletion to another zone. B-3 79 Pioneer Natural Resources USA, Inc. Board of Directors September 3, 1999 Page 4 Oil and natural gas liquids (NGL) reserves are expressed in thousands of United States (U.S.) barrels (MBBL) of 42 U.S. gallons. Gas volumes are expressed in millions of cubic feet (MMCF) at 60 degrees Fahrenheit and at the legal pressure base that prevails in Texas. This report includes only those costs and revenues which are considered by Pioneer USA to be directly attributable to individual leases and areas. There could exist other revenues, overhead costs, or other costs associated with Pioneer USA or the Limited Partners/Converted Limited Partners which are not included in this report. Such additional costs and revenues are outside the scope of this report. This report is not a financial statement for Pioneer USA or the Limited Partners/Converted Limited Partners and should not be used as the sole basis for any transaction concerning Pioneer USA, the Limited Partners/Converted Limited Partners, or the evaluated properties. The reserves projections in this report are based on the use of the available data and accepted industry engineering methods. Future changes in any operational or economic parameters or production characteristics of the evaluated properties could increase or decrease their reserves. Unforeseen changes in market demand or allowables set by various regulatory agencies could also cause actual production rates to vary from those projected. Williamson reserves the right to alter any of the reserves projections and the associated economics included in this evaluation in any future evaluations based on additional data that may be acquired. All data utilized in the preparation of this report with respect to interests, reversionary status, oil and gas prices, gas categories, gas contract terms, operating expenses, investments, salvage values, abandonment costs, net profit interests, well information, and current operating conditions, as applicable, were provided by Pioneer USA. Production data provided by Pioneer USA were utilized. All data have been reviewed for reasonableness and, unless obvious errors were detected, have been accepted as correct. It should be emphasized that revisions to the projections of reserves and economics included in this report may be required if the provided data are revised for any reason. No inspection of the properties was made as this was not considered within the scope of this evaluation. No investigation was made of any environmental liabilities that might apply to the evaluated properties, and no costs are included for any possible related expenses. Since sufficient production history and other data were available, the estimates of reserves contained in this report were determined by extrapolation of historical production trends and in accordance with the Definitions of SEC Reserves included in this summary letter report. Prices for oil sold as of December 31, 1998 were provided by Pioneer USA to be used at the effective date. These prices include adjustments for API gravity, transportation, and any bonus paid. These adjustments were made by Pioneer USA. After the effective date, prices were held constant for the life of the properties. No attempt has been made to account for oil price fluctuations which have occurred in the market subsequent to the effective date of this report. Prices for gas sold as of December 31, 1998 were provided by Pioneer USA to be used at the effective date. These prices include adjustments for British thermal unit content, shrinkage due to NGL removal, transportation and handling charges, and any other known differences between sales and produced volumes. These adjustments were made by Pioneer USA. After the effective date, prices were held constant for the life of the properties unless Pioneer USA indicated that changes were provided for by contract. All gas prices were applied to projected wellhead volumes. Prices for NGL sold as of December 31, 1998 were provided by Pioneer USA to be used at the effective date. NGL reserves were projected as a separate stream using a constant ratio (barrels of NGL/thousand cubic feet of gas) based on historical yields. After the effective date, prices were held constant for the life B-4 80 Pioneer Natural Resources USA, Inc. Board of Directors September 3, 1999 Page 5 of the properties. No attempt has been made to account for price fluctuations which have occurred in the market subsequent to the effective date of this report. It should be emphasized that with the current economic uncertainties, fluctuation in market conditions could significantly change the economics of the properties included in this report. Operating expenses were provided by Pioneer USA and represented, when possible, the latest available 12-month average of all recurring expenses which are billable to the working interest owners. These expenses included, but were not limited to, all direct operating expenses, field overhead costs, and any ad valorem taxes not deducted separately. Expenses for workovers, well stimulations, and other maintenance were not included in the operating expenses unless such work was expected on a recurring basis. Judgments for the exclusion of the nonrecurring expenses were made by Pioneer USA. Any internal indirect overhead costs (general and administrative) which are billable to the working interest owners were included, while those not billable were not included. Operating costs were held constant for the life of the properties. State production and county ad valorem taxes have been deducted at the published rates as provided by Pioneer USA. A 7.5 percent severance tax exemption was applied until September 2001 for qualifying wells. Based on information supplied by Pioneer USA, neither capital costs nor salvage values were included in the projections of reserves and economics in this report. IV. CONSENT AND DECLARATION OF INDEPENDENT STATUS We understand that our estimates are to be included in a Schedule 13e-3 under the Securities Exchange Act of 1934 to be filed by you with the SEC and in the proxy statement included as an exhibit to such Schedule 13e-3. We understand further that the estimates may be used by you to establish merger values for the Partnerships. With this understanding in mind, we have consistently applied the generally accepted petroleum engineering and evaluation principles in estimating the proved oil and gas reserves and in computing the future net revenues derived from such reserves for each property attributable to the interests held by the Partnerships. Williamson is an independent consulting firm and does not own any interests in the oil and gas properties covered by this report. No employee, officer, or director of Williamson is an employee, officer, or director of Pioneer USA or any of the subject partnerships. Neither the employment of nor the compensation received by Williamson is contingent upon the values assigned to the properties covered by this report.

STANGER & CO., INC. [LETTERHEAD OF ROBERT A. STANGER & CO., INC.] PRELIMINARY DRAFT (subject to change) , 1999 Pioneer Natural Resources USA, Inc. 1400 Williams Square West 5205 North O'Connor Boulevard Irving, Texas 75039 Attention: Board of Directors Gentlemen: Pioneer Natural Resources USA, Inc. ("Pioneer USA"), the sole or managing general partner of the partnerships identified in Exhibit I attached hereto ("the Partnerships"), has advised us that the Partnerships are contemplating a transaction (the "Transaction") pursuant to an agreement (the "Merger Agreement") in which the Partnerships will merge with and into Pioneer USA and the interests of the limited partners (the "Limited Partners") in each Partnership will be converted into the right to receive cash equal to the estimated value of such Partnership's oil and gas reserves (the "Reserve Value") and net working capital (the "Working Capital Balance") as of , 1999 (collectively, the Reserve Value and the Working Capital Balance are referred to herein as the "Merger Value"). We have been advised that the Merger Value will be determined and paid to holders of limited partnership interests (the "Limited Partner Interests") of each Partnership in accordance with the provisions of the Partnership agreement of each Partnership relating to a liquidation of the Partnership. We have been further advised that the Reserve Value has been established by Pioneer USA and its parent company, Pioneer Natural Resources Company ("Pioneer"), based upon the present value of estimated future net revenues (after certain expenses and charges) from each Partnership's proved oil and gas reserves as of , 1999 utilizing prices of $ per barrel of oil and $ per thousand cubic feet of gas, and a discount rate of %, (the "Reserve Analysis"). We have been further advised that , an independent petroleum engineering firm, has reviewed the Reserve Analysis of each Partnership and has issued a report thereon confirming the determination of the Reserve Value (the "Consultant's Report"). We have been advised that the Limited Partners in each Partnership will have the opportunity to approve or reject the participation by their Partnership in the Transaction pursuant to a proxy statement and a Limited Partners' meeting which will be prepared and held, respectively, in connection with the Transaction, and further that Limited Partners in each Partnership will receive only cash in exchange for Limited Partner Interests. You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide an opinion as to the fairness, from a financial point of view, of the Merger Value to be paid in cash for Limited Partner Interests in each Partnership in connection with the Transaction. Stanger, founded in 1978, has provided research, investment banking and consulting services to clients located throughout the United States, including major New York Stock Exchange member firms and insurance companies and over seventy companies engaged in the management and operations of partnerships. The investment banking activities of Stanger include financial advisory services, asset and securities valuations, industry and company research and analysis, litigation support and expert witness services, and due diligence investigations in connection with both publicly registered and privately placed securities transactions. C-1 86 Stanger, as part of its investment banking business, is regularly engaged in the valuation of securities in connection with mergers, acquisitions, and reorganizations and for estate, tax, corporate and other purposes. In particular, Stanger's valuation practice principally involves partnerships, partnership securities and assets typically owned through partnerships including, but not limited to, oil and gas reserves, real estate, mortgages secured by real estate, cable television systems, and equipment leasing assets. In arriving at the opinion set forth below, we have: - Reviewed a draft of the Merger Agreement which Pioneer USA has indicated to be in substantially the form which will be executed in connection with the Transaction. - Reviewed the financial statements of the Partnerships for the years ended December 31, 1997 and 1998 and the six months ended June 30, 1999; - Reviewed the Reserve Analysis of each Partnership prepared by Pioneer USA and Pioneer as of , 1999; - Reviewed the Consultant's Report for each Partnership prepared by Williamson Petroleum Consultants, Inc. as of , 1999; - Reviewed the calculations prepared by Pioneer USA and Pioneer of the Merger Value per unit of Limited Partner Interest in each Partnership; - Reviewed estimates prepared by Pioneer USA and Pioneer of the going-concern value and liquidation value per unit of Limited Partner Interest in each Partnership; - Interviewed key management personnel of Pioneer USA regarding the oil and gas reserves, the financial condition of each Partnership and the terms of the Transaction; and - Conducted such other studies, analyses, inquiries and investigations as we deemed appropriate. In rendering this opinion, we have relied, without independent verification, on the accuracy and completeness in all material respects of all financial and other information that was furnished or otherwise communicated to us by Pioneer USA, Pioneer and the Partnerships. We have been advised by Pioneer USA and Pioneer that the oil and gas properties owned by the Partnerships are subject to operating agreements (the "Operating Agreements") with Pioneer USA and that: (i) such Operating Agreements provide for the payment of overhead charges and that such charges are reasonable compared with amounts charged for similar services by third-party operators; (ii) except for cause, such Operating Agreements do not provide for the termination of Pioneer USA as operator; and (iii) such Operating Agreements do not provide for the revision of the overhead charges, except as escalated under the terms of such Operating Agreements. Furthermore, we have been advised by Pioneer USA and Pioneer that if each Partnership's reserves were offered for sale to a third party, a condition of such sale would be that the oil and gas reserves would continue to be subject to the Operating Agreements with Pioneer USA which provide for the payment of overhead charges, and that it would be appropriate to assume, when estimating the value of such reserves, that such expenses and charges would continue. We have also been advised that the Reserve Value and Working Capital Balance of each Partnership has been properly allocated between Pioneer USA and Limited Partners of each Partnership in accordance with the Partnership Agreement with respect to a liquidation of such Partnership. We have not performed an independent appraisal of the oil and gas reserves or other assets and liabilities of the Partnerships. We have not conducted any engineering studies and have relied on estimates of Pioneer USA and Pioneer with respect to oil and gas reserve volumes, prices, operating costs, general and administrative expenses and overhead charges. We have relied on the assurance of Pioneer USA, Pioneer and the Partnerships that: (i) the Reserve Analysis provided to us was in the judgment of Pioneer USA and the Partnerships reasonably prepared on bases consistent with actual historical experience and reflect their best currently available estimates and C-2 87 good faith judgments; (ii) any estimates of costs to remediate environmental conditions included in the Reserve Analysis are based on detailed analyses and reflect the best currently available estimates and good faith judgments; (iii) any historical financial data, balance sheet data, transaction cost estimates, Merger Value analyses, going-concern value analyses and liquidation value analyses are accurate and complete in all material respects; (iv) all calculations of Reserve Values, Working Capital Balances, Merger Values, going-concern values and liquidation values have been made in accordance with the Partnership Agreement for each Partnership; (v) no material changes have occurred in the information reviewed or in the value of the oil and gas reserves or Working Capital Balances of each Partnership between the date the information was provided to us and the date of this letter; and (vi) Pioneer USA, Pioneer and the Partnerships are not aware of any information or facts regarding the Partnerships, the oil and gas properties, the Reserve Analysis or the Working Capital Balances of each Partnership that would cause the information supplied to us to be incomplete or misleading in any material respect. We have not been requested to, and therefore did not: (i) make any recommendation to Pioneer USA, the Partnerships or the Limited Partners with respect to whether to approve or reject the Transaction; (ii) determine or negotiate the amount or form of the Merger Value to be paid for Limited Partner Interests in the Transaction; (iii) offer the assets of the Partnerships for sale to any third party; (iv) express any opinion as to: (a) the impact of the Transaction with respect to Pioneer USA or the Limited Partners of any Partnerships that do not participate in the Transaction; (b) the tax consequences of the Transaction for Pioneer USA or the Limited Partners of any Partnership; (c) Pioneer's or Pioneer USA's ability to finance their obligations pursuant to the Merger Agreement or the impact of a failure to obtain financing on the financial performance of Pioneer, Pioneer USA or the Partnerships; (d) Pioneer USA's decision to estimate the Reserve Value of the oil and gas reserves of each Partnership based upon the continued operation of the properties by Pioneer USA and the payment of overhead charges in accordance with existing Operating Agreements or the impact, if any, on the estimated values of the Partnerships' oil and gas reserves if Pioneer USA and Pioneer determined to offer or operate the assets subject to revised Operating Agreements; (e) whether or not alternative methods of determining the Merger Value would have also provided fair results or results substantially similar to the methodology used; (f) alternatives to the Transaction, including the offering of such assets for sale to third-party buyers; or (g) the fairness of the amount or allocation of transaction costs; or (h) any other terms of the Transaction. This letter does not purport to be a complete description of the analyses performed or the matters considered in rendering this opinion. The analyses and the summary set forth herein must be considered as a whole, and selecting portions of such summary or analyses without considering all factors and analyses would create an incomplete view of the process underlying this opinion. In rendering this opinion, judgment was applied to a variety of complex analyses and assumptions. The assumptions made and the judgments applied in rendering the opinion are not readily susceptible to partial analysis or summary description. The fact that any specific analysis is referred to herein is not meant to indicate that such analysis was given greater weight than any other analyses. Our opinion is based on business, economic, oil and gas market, and other conditions as of the date of our analysis and addresses the Merger Value in the context of information available as of the date of our analysis. Events occurring after that date could affect the value of the assets of the Partnerships or the assumptions used in preparing this opinion. C-3 88 Based upon and subject to the foregoing, it is our opinion that, as of the date of this letter and subject to the assumptions, limitations and qualifications contained herein, the Merger Value to be paid in cash for the Limited Partner Interests in connection with the Transaction is fair from a financial point of view to the Limited Partners of each respective Partnership.

The merger value assigned to each Partnership and the amount of cash offered with respect to each $1,000 investment by the limited partners in such Partnership pursuant to the mergers are set forth on Exhibit A hereto opposite the name of such Partnership.

(A DELAWARE LIMITED PARTNERSHIP) NOTES TO FINANCIAL STATEMENTS JUNE 30, 1999 (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 primarily 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 June 30, 1999 and for the three and six months ended June 30, 1999 and 1998 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 information and footnote disclosure 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, 1998 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, 1400 Williams Square West, Irving, Texas 75039-3746. 7 130 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS(1) RESULTS OF OPERATIONS Six months ended June 30, 1999 compared with six months ended June 30, 1998 Revenues: The Partnership's oil and gas revenues decreased 14% to $374,957 from $434,947 for the six months ended June 30, 1999 and 1998, respectively. The decrease in revenues resulted from lower average prices received and a decrease in production. For the six months ended June 30, 1999, 17,589 barrels of oil, 11,663 barrels of natural gas liquids ("NGLs") and 45,216 mcf of gas were sold, or 36,788 barrel of oil equivalents ("BOEs"). For the six months ended June 30, 1998, 19,552 barrels of oil, 10,141 barrels of NGLs and 46,285 mcf of gas were sold, or 37,407 BOEs. The average price received per barrel of oil decreased $1.65, or 11%, from $14.65 for the six months ended June 30, 1998 to $13.00 for the same period in 1999. The average price received per barrel of NGLs decreased 7% from $7.39 during the six months ended June 30, 1998 to $6.86 for the same period in 1999. The average price received per mcf of gas decreased 8% from $1.59 during the six months ended June 30, 1998 to $1.47 in 1999. The market price for oil and gas has been extremely volatile in the past decade, and management expects a certain amount of volatility to continue in the foreseeable future. The Partnership may therefore sell its future oil and gas production at average prices lower or higher than that received during the six months ended June 30, 1999. The volatility of commodity prices has had, and continues to have, a significant impact on the Partnership's revenues and operating cash flow and could result in additional decreases to the carrying value of the Partnership's oil and gas properties. Costs and Expenses: Total costs and expenses decreased to $343,476 for the six months ended June 30, 1999 as compared to $402,718 for the same period in 1998, a decrease of $59,242, or 15%. This decrease was due to declines in production costs, depletion and general and administrative expenses ("G&A"). Production costs were $223,897 for the six months ended June 30, 1999 and $272,903 for the same period in 1998 resulting in a $49,006 decrease, or 18%. The decrease was due to declines in well maintenance costs and production taxes. G&A's components are independent accounting and engineering fees and managing general partner personnel and operating costs. During this period, G&A decreased, in aggregate, 19% from $13,920 for the six months ended June 30, 1998 to $11,249 for the same period in 1999. Depletion was $108,330 for the six months ended June 30, 1999 compared to $115,895 for the same period in 1998, a decrease of $7,565, or 7%. This decrease was due to a reduction in oil production of 1,963 barrels for the six months ended June 30, 1999 compared to the same period in 1998, an increase in proved reserves during the period ended June 30, 1999 due to the higher commodity prices and a reduction in the Partnership's net depletable basis from charges taken 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") during the fourth quarter of 1998. Three months ended June 30, 1999 compared with three months ended June 30, 1998 Revenues: The Partnership's oil and gas revenues increased 3% to $209,933 from $203,910 for the three months ended June 30, 1999 and 1998, respectively. The increase in revenues resulted from higher average prices received and an increase in production. For the three months ended June 30, 1999, 7,934 barrels of oil, 6,797 barrels of NGLs and 24,720 mcf of gas were sold, or 18,851 BOEs. For the three months ended June 30, 1998, 9,573 barrels of oil, 4,934 barrels of NGLs and 21,016 mcf of gas were sold, or 18,010 BOEs. 8 131 The average price received per barrel of oil increased 4% from $13.87 for the three months ended June 30, 1998 to $14.48 for the same period in 1999. The average price received per barrel of NGLs increased 8% from $7.62 during the three months ended June 30, 1998 to $8.21 for the same period in 1999. The average price received per mcf of gas decreased slightly from $1.60 during the three months ended June 30, 1998 to $1.59 in 1999. Costs and Expenses: Total costs and expenses decreased to $159,581 for the three months ended June 30, 1999 as compared to $200,434 for the same period in 1998, a decrease of $40,853, or 20%. This decrease was due to declines in depletion, production costs and G&A. Production costs were $122,011 for the three months ended June 30, 1999 and $133,653 for the same period in 1998 resulting in an $11,642 decrease, or 9%. The decrease was due to declines in well maintenance costs, ad valorem taxes and production taxes. During this period, G&A decreased, in aggregate, 10% from $6,989 for the three months ended June 30, 1998 to $6,298 for the same period in 1999. Depletion was $31,272 for the three months ended June 30, 1999 compared to $59,792 for the same period in 1998, a decrease of $28,520, or 48%. This decrease was primarily attributable to an increase in proved reserves during the period ended June 30, 1999 due to higher commodity prices, a reduction in oil production of 1,639 barrels for the three months ended June 30, 1999 compared to the same period in 1998 and a reduction in the Partnership's net depletable basis from charges taken in accordance with SFAS 121 during the fourth quarter of 1998. LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities decreased $109,049 during the six months ended June 30, 1999 from the same period ended June 30, 1998. This decrease was primarily due to declines in oil and gas sales receipts, offset by declines in production costs and G&A expenses paid. Net Cash Used in Investing Activities The Partnership's principal investing activities during the six months ended June 30, 1999 and 1998 included expenditures for equipment replacement on various oil and gas properties. Net Cash Used in Financing Activities Cash was sufficient for the six months ended June 30, 1999 to cover distributions to the partners of $81,243 of which $812 was distributed to the managing general partner and $80,431 to the limited partners. For the same period ended June 30, 1998, cash was sufficient for distributions to the partners of $240,306 of which $2,403 was distributed to the managing general partner and $237,903 to the limited partners. From the third quarter of 1997 through the first quarter of 1999, there was a declining trend in oil and gas levels. During the first quarter of 1999, the Organization of Petroleum Exporting Countries and certain other crude oil exporting nations announced reductions in their planned export volumes. These announcements, together with early indications that the nations have initiated their planned reductions, have had some stabilizing effect on commodity prices during the latter part of the first quarter of 1999 and into August 1999. However, no assurances can be given that the stabilizing effect of these actions, or the planned reductions in export volumes, will be sustained for an extended period of time. 9 132 YEAR 2000 PROJECT READINESS Historically, many computer programs have been developed that use only the last two digits in a date to refer to a year. As the year 2000 nears, the inability of such computer programs and embedded technologies to distinguish between "1900" and "2000" has given rise to the "Year 2000" problem. Theoretically, such computer programs and related technology could fail outright, or communicate inaccurate data, if not remediated or replaced. With the proliferation of electronic data interchange, the Year 2000 problem represents a significant exposure to the entire global community, the full extent of which cannot be accurately assessed. In proactive response to the Year 2000 problem, the managing general partner established a "Year 2000" project to assess, to the extent possible, the Partnership's and the managing general partner's internal Year 2000 problem; to take remedial actions necessary to minimize the Year 2000 risk exposure to the managing general partner and significant third parties with whom it has data interchange; and, to test its systems and processes once remedial actions have been taken. The managing general partner has contracted with IBM Global Services to perform the assessment and remedial phases of its Year 2000 project. As of June 30, 1999, the managing general partner estimates that the assessment phase is approximately 99% complete and has included, but is not limited to, the following procedures: - the identification of necessary remediation, upgrade and/or replacement of existing information technology applications and systems; - the assessment of non-information technology exposures, such as telecommunications systems, security systems, elevators and process control equipment; - the initiation of inquiry and dialogue with significant third party business partners, customers and suppliers in an effort to understand and assess their Year 2000 problems, readiness and potential impact on the managing general partner and its Year 2000 problem; - the implementation of processes designed to reduce the risk of reintroduction of Year 2000 problems into the managing general partner's systems and business processes; and, - the formulation of contingency plans for mission-critical information technology systems. Through June 30, 1999, the managing general partner had distributed Year 2000 problem inquiries to over 500 entities and has received responses to approximately 52% of the inquiries. The remedial phase of the managing general partner's Year 2000 project is in varying stages of completion as it pertains to the remediation of information technology and non-information technology applications and systems in the United States, Canada and Argentina. As of June 30, 1999, the managing general partner estimates that the remedial phase is approximately 83% complete, on a worldwide basis, subject to continuing evaluations of the responses to third party inquiries and to the testing phase results. The remedial phase has included the upgrade and/or replacement of certain application and hardware systems. The managing general partner has upgraded its Artesia general ledger accounting systems through remedial coding and has completed the testing of the system for Year 2000 compliance. The remediation of non-information technology is expected to be completed by October 1999. The managing general partner's Year 2000 remedial actions have not delayed other information technology projects or upgrades. The testing phase of the managing general partner's Year 2000 project is on schedule. The managing general partner expects to complete the testing of information technology systems by October 1999. The testing of the non-information technology remediation is scheduled to be completed by the end of November 1999. The managing general partner expects that its total costs related to the Year 2000 problem will approximate $3.6 million, of which approximately $500 thousand will have been incurred to replace non-compliant information technology systems. As of June 30, 1999, the managing general partner's total costs 10 133 incurred on the Year 2000 problem were $2.3 million, of which approximately $200 thousand were incurred to replace non-compliant systems. The risks associated with the Year 2000 problem are significant. A failure to remedy a critical Year 2000 problem could have a materially adverse affect on the Partnership's results of operations and financial condition. The most likely worst case scenario which may be encountered as a result of a Year 2000 problem could include information and non-information system failures, the receipt or transmission of erroneous data, lost data or a combination of similar problems of a magnitude that cannot be accurately assessed at this time. In the business continuity and contingency planning phase of the managing general partner's Year 2000 project, contingency plans were designed to mitigate the exposures to mission critical information technology systems, such as oil and gas sales receipts, vendor and royalty cash distributions, debt compliance, accounting, and employee compensation. Such contingency plans anticipate the extensive utilization of third-party data processing services, personal computer applications and the substitution of courier and mail services in place of electronic data interchange. Given the uncertainties regarding the scope of the Year 2000 problem and the compliance of significant third parties, there can be no assurance that contingency plans will have anticipated all Year 2000 scenarios. - --------------- (1) "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" contains forward looking statements that involve risks and uncertainties.

Business" for a description of various factors that could materially affect the ability of the Partnership to achieve the anticipated results described in the forward looking statements. PART I ITEM 1. BUSINESS Parker & Parsley 88-A, L.P. (the "Partnership") is a limited partnership organized in 1988 under the laws of the State of Delaware. As of August 8, 1997, Pioneer Natural Resources USA, Inc. ("Pioneer USA") became the managing general partner of the Partnership. Prior to August 8, 1997, the Partnership's managing general partner was Parker & Parsley Development L.P. ("PPDLP"), a wholly-owned subsidiary of Parker & Parsley Petroleum Company ("Parker & Parsley"). On August 7, 1997, Parker & Parsley and Mesa Inc. ("Mesa") received shareholder approval to merge and create Pioneer Natural Resources Company ("Pioneer"). On August 8, 1997, PPDLP was merged with and into Pioneer USA, a wholly-owned subsidiary of Pioneer, resulting in Pioneer USA becoming the managing general partner of the Partnership as PPDLP's successor by merger. For a more complete description of the Parker & Parsley and Mesa merger, see Pioneer's Registration Statement on Form S-4 as filed with the Securities & Exchange Commission. A Registration Statement, as amended, filed pursuant to the Securities Act of 1933, registering limited partnership interests aggregating $70,000,000 in a series of Delaware limited partnerships formed under the Parker & Parsley 88 Development Drilling Program, was declared effective by the Securities and Exchange Commission on March 4, 1988. On June 30, 1988, the offering of limited partnership interests in the Partnership, the first partnership formed under such statement, was closed, with interests aggregating $12,935,000 being sold to 999 subscribers. The Partnership engages primarily in oil and gas development and production and is not involved in any industry segments other than oil and gas. See "Item 6. Selected Financial Data" and "Item 8. Financial Statements and Supplementary Data" of this report for a summary of the Partnership's revenue, income and identifiable assets. The principal markets during 1998 for the oil produced by the Partnership were refineries and oil transmission companies that have facilities near the Partnership's oil producing properties. The principal markets for the Partnership's gas were companies that have pipelines located near the Partnership's gas producing properties. Of the Partnership's total oil and gas revenues for 1998, approximately 55% and 22% were attributable to sales made to Genesis Crude Oil, L.P. and Western Gas Resources, Inc., respectively. The Partnership's revenues, profitability, cash flow and future rate of growth are highly dependent on the prevailing prices of oil and gas, which are affected by numerous factors beyond the Partnership's control. Oil and gas prices historically have been very volatile. A substantial or extended decline in the prices of oil or gas could have a material adverse effect on the Partnership's revenues, profitability and cash flow and could, under certain circumstances, result in a reduction in the carrying value of the Partnership's oil and gas properties. Because of the demand for oil and gas, the Partnership does not believe that the termination of the sales of its products to any one customer would have a material adverse impact on its operations. The loss of a particular customer for gas may have an effect if that particular customer has the only gas pipeline located in the areas of the Partnership's gas producing properties. The Partnership believes, however, that the effect would be temporary, until alternative arrangements could be made. 1 137 Federal and state regulation of oil and gas operations generally includes the fixing of maximum prices for regulated categories of natural gas, the imposition of maximum allowable production rates, the taxation of income and other items, and the protection of the environment. Although the Partnership believes that its business operations do not impair environmental quality and that its costs of complying with any applicable environmental regulations are not currently significant, the Partnership cannot predict what, if any, effect these environmental regulations may have on its current or future operations. The Partnership does not have any employees of its own. Pioneer USA employs 818 persons, many of whom dedicated a part of their time to the conduct of the Partnership's business during the period for which this report is filed. Pioneer USA is responsible for all management functions. Numerous uncertainties exist in estimating quantities of proved reserves and future net revenues therefrom. The estimates of proved reserves and related future net revenues set forth in this report are based on various assumptions, which may ultimately prove to be inaccurate. Therefore, such estimates should not be construed as estimates of the current market value of the Partnership's proved reserves. No material part of the Partnership's business is seasonal and the Partnership conducts no foreign operations. ITEM 2. PROPERTIES The Partnership's properties consist primarily of leasehold interests in properties on which oil and gas wells are located. Such property interests are often subject to landowner royalties, overriding royalties and other oil and gas leasehold interests. Fractional working interests in developmental oil and gas prospects located in the Spraberry Trend area of West Texas were acquired by the Partnership, resulting in the Partnership's participation in the drilling of 40 oil and gas wells. At December 31, 1998, 39 wells were producing with one well plugged and abandoned. For information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1998, 1997 and 1996, and changes in such quantities for the years then ended, see Note 7 of Notes to Financial Statements included in "Item 8. Financial Statements and Supplementary Data" below. Such reserves have been estimated by the engineering staff of Pioneer USA with a review by Williamson Petroleum Consultants, Inc., an independent petroleum consultant. ITEM 3. LEGAL PROCEEDINGS The Partnership from time to time is a party to various legal proceedings incidental to its business involving claims in oil and gas leases or interests, other claims for damages in amounts not in excess of 10% of its current assets and other matters, none of which Pioneer believes to be material to the Partnership. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS There were no matters submitted to a vote of security holders during the fourth quarter of 1998. 2 138 PART II ITEM 5. MARKET FOR PARTNERSHIP'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS At March 8, 1999, the Partnership had 12,935 outstanding limited partnership interests held of record by 977 subscribers. There is no established public trading market for the limited partnership interests. Under the limited partnership agreement, Pioneer USA has made certain commitments to purchase partnership interests at a computed value. Revenues which, in the sole judgement of the managing general partner, are not required to meet the Partnership's obligations, are distributed to the partners at least quarterly in accordance with the limited partnership agreement. During the years ended December 31, 1998 and 1997, $360,933 and $655,601, respectively, of such revenue-related distributions were made to the limited partners. ITEM 6.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS 1998 compared to 1997 The Partnership's 1998 oil and gas revenues decreased 33% to $774,533 from $1,157,862 in 1997. The decrease in revenues resulted from lower average prices received. In 1998, 37,135 barrels of oil, 20,500 barrels of natural gas liquids ("NGLs") and 86,501 mcf of gas were sold, or 72,052 barrel of oil equivalents ("BOEs"). In 1997, 38,859 barrels of oil, 9,410 barrels of NGLs and 134,311 mcf of gas were sold, or 70,654 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. Consistent with the managing general partner, the Partnership has historically accounted for processed natural gas production as wellhead production on a wet gas basis. Effective September 30, 1997, as a result of the merger with Mesa, the managing general partner accounts for processed natural gas production in two components: natural gas liquids and dry residue gas. As a result of the change in the managing general 3 139 partner's policy, the Partnership now accounts for processed natural gas production as processed natural gas liquids and dry residue gas. Consequently, separate product volumes will not be comparable for periods prior to September 30, 1997. Also, prices for gas products will not be comparable as the price per mcf for natural gas for the year ended December 31, 1998 is the price received for dry residue gas and the price per mcf for natural gas produced prior to October 1997 was presented as a price for wet gas (i.e., natural gas liquids combined with dry residue gas). The average price received per barrel of oil decreased $5.77, or 30%, from $19.36 in 1997 to $13.59 in 1998. The average price received per barrel of NGLs decreased $3.94, or 37%, from $10.51 in 1997 to $6.57 in 1998. The average price received per mcf of gas decreased 32% from $2.28 in 1997 to $1.56 in 1998. The market price for oil and gas has been extremely volatile in the past decade, and management expects a certain amount of volatility to continue in the foreseeable future. The Partnership may therefore sell its future oil and gas production at average prices lower or higher than that received in 1998. A gain on disposition of assets of $6,393 was recognized in 1998 for credits received from the disposal of oil and gas equipment on a fully depleted well. Total costs and expenses decreased in 1998 to $1,306,368 as compared to $1,501,465 in 1997, a decrease of $195,097, or 13%. The decrease was primarily due to declines in the impairment of oil and gas properties, production costs and general and administrative expenses ("G&A"), offset by an increase in depletion. Production costs were $508,919 in 1998 and $513,147 in 1997, resulting in a $4,228 decrease. The decrease was due to reductions in workover expenses, ad valorem taxes and production taxes, offset by an increase in well maintenance costs incurred in an effort 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, in aggregate, 33% from $35,452 in 1997 to $23,611 in 1998. The Partnership paid the managing general partner $19,297 in 1998 and $30,932 in 1997 for G&A incurred on behalf of the Partnership. G&A is allocated, in part, to the Partnership by the managing general partner. Such allocated expenses are determined by the managing general partner based upon its judgement of the level of activity of the Partnership relative to the managing general partner's activities and other entities it manages. The method of allocation has been consistent over the past several years with certain modifications incorporated to reflect changes in Pioneer USA's overall business activities. In accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121"), the managing general partner reviews the Partnership's oil and gas properties for impairment whenever events or circumstances indicate a decline in the recoverability of the carrying value of the Partnership's assets may have occurred. Declining commodity prices prompted impairment reviews in 1998 and 1997. As a result of the review and evaluation of its long-lived assets for impairment, the Partnership recognized non-cash charges of $405,308 and $699,976 related to its oil and gas properties during 1998 and 1997, respectively. Depletion was $368,530 in 1998 compared to $252,890 for the same period in 1997, representing an increase of $115,640, or 46%. This increase was the result of a decline in proved reserves during 1998 due to the lower commodity prices, offset by a reduction in the Partnership's net depletable basis from charges taken in accordance with SFAS 121 during the fourth quarter of 1997 and a reduction in oil production of 1,724 barrels for the period ended December 31, 1998 compared to the same period in 1997. 1997 compared to 1996 The Partnership's 1997 oil and gas revenues decreased 18% to $1,157,862 from $1,411,568 in 1996. The decrease in revenues resulted from declines in production and lower average prices received. In 1997, 38,859 barrels of oil, 9,410 barrels of NGLs and 134,311 mcf of gas were sold, or 70,654 BOEs. In 1996, 44,670 barrels of oil and 170,774 mcf of gas were sold, or 73,132 BOEs. 4 140 Consistent with the managing general partner, the Partnership has historically accounted for processed natural gas production as wellhead production on a wet gas basis. As is described above in "Results of Operations -- 1998 compared to 1997", the Partnership changed its method of accounting for processed natural gas to a dry gas basis in the fourth quarter of 1997. As a result of this change, the Partnership now accounts for processed natural gas production as processed natural gas liquids and dry residue gas. Consequently, 1997 and 1996 separate product volumes are not comparable. The declines in production volumes were primarily attributable to the decline characteristics of the Partnership's oil and gas properties. The average price received per barrel of oil decreased $2.45, or 11%, from $21.81 in 1996 to $19.36 in 1997. The average price received per barrel of NGLs during 1997 was $10.51. The average price received per mcf of gas decreased 11% from $2.56 in 1996 to $2.28 in 1997. Total costs and expenses increased in 1997 to $1,501,465 as compared to $823,988 in 1996, an increase of $677,477. The increase was primarily due to the impairment of oil and gas properties and an increase in depletion, offset by decreases in production costs and G&A. Production costs were $513,147 in 1997 and $531,610 in 1996, resulting in a $18,463 decrease, or 3%. The decrease was due to reductions in well maintenance costs and production taxes, offset by an increase in workover expenses incurred in an effort to stimulate well production. During this period, G&A decreased, in aggregate, 16% from $42,275 in 1996 to $35,452 in 1997. The Partnership paid the managing general partner $30,932 in 1997 and $38,245 in 1996 for G&A incurred on behalf of the Partnership. The Partnership recognized a non-cash SFAS 121 impairment provision of $699,976 related to its oil and gas properties during the fourth quarter of 1997. Depletion was $252,890 in 1997 compared to $250,103 for the same period in 1996, representing an increase of $2,787. This increase was the result of a decline in oil reserves during 1997 due to the lower commodity prices, offset by the decline in oil production of 5,811 barrels for 1997 as compared to 1996. IMPACT OF INFLATION AND CHANGING PRICES ON SALES AND NET INCOME Inflation impacts the fixed overhead rate charges of the lease operating expenses for the Partnership. During 1998, the annual change in the index of average weekly earnings of crude petroleum and gas production workers issued by the U.S. Department of Labor, Bureau of Labor Statistics increased (effective April 1, 1998) 10.3%. The 1997 annual change in average weekly earnings increased by 2%. The 1996 index increased 4.1%. The impact of inflation for other lease operating expenses is small due to the current economic condition of the oil industry. The oil and gas industry experienced volatility during the past decade because of the fluctuation of the supply of most fossil fuels relative to the demand for such products and other uncertainties in the world energy markets causing significant fluctuations in oil and gas prices. During 1998 the price per barrel for oil production similar to the Partnership's ranged from approximately $9.50 to $15.50. During most of 1997 and 1996, the Partnership benefitted from higher oil prices as compared to previous years. However, during the fourth quarter of 1997, oil prices began a downward trend that has continued into March 1999. On March 8, 1999, the market price for West Texas intermediate crude was $11.00 per barrel. A continuation of the current commodity price environment will continue to have an adverse effect on the Partnership's revenues, operating cash flow and distributions and could result in additional decreases in the carrying value of the Partnership's oil and gas properties. Prices for natural gas are subject to ordinary seasonal fluctuations, and this volatility of natural gas prices may result in production being curtailed and, in some cases, wells being completely shut-in. 5 141 LIQUIDITY AND CAPITAL RESOURCES Net Cash Provided by Operating Activities Net cash provided by operating activities decreased $386,887 during the year ended December 31, 1998 from the year ended December 31, 1997. The decrease was due to a decline in oil and gas sales receipts and an increase in production costs paid, offset by a decrease in G&A expenses paid. Net Cash Used in Investing Activities The Partnership's investing activities during 1998 and 1997 were related to the addition of oil and gas equipment on active properties. Proceeds from asset dispositions of $16,559 were received during 1998 consisting of $10,166 from equipment credits received on active properties and $6,393 was due to equipment credits received on one fully depleted well. Net Cash Used in Financing Activities Cash was sufficient in 1998 for distributions to the partners of $364,579 of which $3,646 was distributed to the managing general partner and $360,933 to the limited partners. In 1997, cash was sufficient for distributions to the partners of $662,223 of which $6,622 was distributed to the managing general partner and $655,601 to the limited partners. The current commodity price environment will continue to impact the distributions and could result in limited or no distributions to the partners. YEAR 2000 PROJECT READINESS Historically, many computer programs have been developed that use only the last two digits in a date to refer to a year. As the year 2000 nears, the inability of such computer programs and embedded technologies to distinguish between "1900" and "2000" has given rise to the "Year 2000" problem. Theoretically, such computer programs and related technology could fail outright or communicate inaccurate data, if not remediated or replaced. With the proliferation of electronic data interchange, the Year 2000 problem represents a significant exposure to the entire global community, the full extent of which cannot be accurately assessed. In proactive response to the Year 2000 problem, the managing general partner established a "Year 2000" project to assess, to the extent possible, the Partnership's and the managing general partner's internal Year 2000 problem; to take remedial actions necessary to minimize the Year 2000 risk exposure to the managing general partner and significant third parties with whom it has data interchange; and, to test its systems and processes once remedial actions have been taken. The managing general partner has contracted with IBM Global Services to perform the assessment and remedial phases of its Year 2000 project. The assessment phase of the managing general partner's Year 2000 project is at varying stages of completion as it pertains to information technology and non-information technology applications and systems in the United States, Canada and Argentina. As of December 31, 1998, the managing general partner estimates that the assessment phase is approximately 86% complete, on a worldwide basis, and has included, but is not limited to, the following procedures: - the identification of necessary remediation, upgrade and/or replacement of existing information technology applications and systems; - the assessment of non-information technology exposures, such as telecommunications systems, security systems, elevators and process control equipment; 6 142 - the initiation of inquiry and dialogue with significant third party business partners, customers and suppliers in an effort to understand and assess their Year 2000 problems, readiness and potential impact on the managing general partner and its Year 2000 problem; - the implementation of processes designed to reduce the risk of reintroduction of Year 2000 problems into the managing general partner's systems and business processes; and, - the formulation of contingency plans for mission-critical information technology systems. The managing general partner expects to complete the assessment phase of its Year 2000 project by the end of the first quarter of 1999 but is being delayed by limited responses received on inquiries made of third party businesses. To date, the managing general partner has distributed Year 2000 problem inquiries to over 500 entities and has received responses to approximately 37% of those inquiries. The remedial phase of the managing general partner's Year 2000 project is also at varying stages of completion as it pertains to the remediation of information technology and non-information technology applications and systems in the United States, Canada and Argentina. As of December 31, 1998, the managing general partner estimates that the remedial phase is approximately 54% complete, on a worldwide basis, subject to the continuing results of the third party inquiry assessments and the testing phase. The remedial phase has included the upgrade and/or replacement of certain application and hardware systems. The managing general partner has upgraded its Artesia general ledger accounting systems through remedial coding and is currently testing this system for Year 2000 compliance. The remediation of non-information technology is expected to be completed during July 1999. The managing general partner's Year 2000 remedial actions have not significantly delayed other information technology projects or upgrades. The testing phase of the managing general partner's Year 2000 project is on schedule. The managing general partner expects to complete the testing of the Artesia system upgrades by March 1999 and all other information technology systems and non-information technology remediation by the end of the third quarter of 1999. The managing general partner expects that its total costs related to the Year 2000 problem will approximate $3.6 million, of which approximately $500 thousand will have been incurred to replace non-compliant information technology systems. The managing general partner intends to use its working capital to pay for the costs of the Year 2000 projects. As of December 31, 1998, the managing general partner's total costs incurred on the Year 2000 problem were $1.8 million, of which $200 thousand were incurred to replace non-compliant systems. The managing general partner will allocate a portion of the costs of the Year 2000 programming charges to the Partnership in accordance with the general and administration allocation. (See Note 2 of Notes to Financial Statements included in "Item 8. Financial Statements and Supplementary Data".) The risks associated with the Year 2000 problem are significant. A failure to remedy a critical Year 2000 problem could have a materially adverse affect on the Partnership's results of operations and financial condition. The most likely worst case scenario which may be encountered as a result of a Year 2000 problem could include information and non-information system failures, the receipt or transmission of erroneous data, lost data or a combination of similar problems of a magnitude that cannot be accurately assessed at this time. In the assessment phase of the managing general partner's Year 2000 project, contingency plans are being designed to mitigate the exposures to mission-critical information technology systems, such as oil and gas sales receipts, vendor and royalty cash distributions, debt compliance, accounting, and employee compensation. Such contingency plans anticipate the extensive utilization of third-party data processing services, personal computer applications and the substitution of courier and mail services in place of electronic data interchange. Given the uncertainties regarding the scope of the Year 2000 problem and the compliance of significant third parties, there can be no assurance that contingency plans will have anticipated all Year 2000 scenarios. 7 143 ITEM 8.

(A DELAWARE LIMITED PARTNERSHIP) NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, 1997 AND 1996 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. As of August 8, 1997, Pioneer Natural Resources USA, Inc. ("Pioneer USA") became the managing general partner of the Partnership. Prior to August 8, 1997, the Partnership's managing general partner was Parker & Parsley Development L.P. ("PPDLP"), a wholly-owned subsidiary of Parker & Parsley Petroleum Company ("Parker & Parsley"). On August 7, 1997, Parker & Parsley and Mesa Inc. ("Mesa") received shareholder approval to merge and create Pioneer Natural Resources Company ("Pioneer"). On August 8, 1997, PPDLP was merged with and into Pioneer USA, a wholly-owned subsidiary of Pioneer, resulting in Pioneer USA becoming the managing general partner of the Partnership as PPDLP's successor by merger. The Partnership engages primarily in oil and gas development and production in Texas and is not involved in any industry segment other than oil and gas. NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A summary of the significant accounting policies consistently applied in the preparation of the accompanying financial statements follows: Oil and gas properties -- The Partnership utilizes the successful efforts method of accounting for its oil and gas properties and equipment. Under this method, all costs associated with productive wells and nonproductive development wells are capitalized while nonproductive exploration costs are expensed. Capitalized costs relating to proved properties are depleted using the unit-of-production method on a property-by-property basis based on proved oil (dominant mineral) reserves as determined by the engineering staff of Pioneer USA, the Partnership's managing general partner, and reviewed by independent petroleum consultants. The carrying amounts of properties sold or otherwise disposed of and the related allowances for depletion are eliminated from the accounts and any gain or loss is included in operations. Impairment of long-lived assets -- In accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121"), the Partnership reviews its long-lived assets to be held and used on an individual property basis, including oil and gas properties accounted for under the successful efforts method of accounting, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future cash flows is less than the carrying amount of the assets. In this circumstance, the Partnership recognizes an impairment loss for the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset. Use of estimates in the preparation of financial statements -- Preparation of the accompanying financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reporting amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Net income (loss) per limited partnership interest -- The net income (loss) per limited partnership interest is calculated by using the number of outstanding limited partnership interests. Income taxes -- A Federal income tax provision has not been included in the financial statements as the income of the Partnership is included in the individual Federal income tax returns of the respective partners. 15 151 PARKER & PARSLEY 88-A, L.P. (A DELAWARE LIMITED PARTNERSHIP) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) Statements of cash flows -- For purposes of reporting cash flows, cash includes depository accounts held by banks. General and administrative expenses -- General and administrative expenses are allocated in part to the Partnership by the managing general partner or its affiliates. Such allocated expenses are determined by the managing general partner based upon its judgement of the level of activity of the Partnership relative to the managing general partner's activities and other entities it manages. The method of allocation has been consistent over the past several years with certain modifications incorporated to reflect changes in Pioneer USA's overall business activities. Reclassifications -- Certain reclassifications may have been made to the 1997 and 1996 financial statements to conform to the 1998 financial statement presentations. Environmental -- The Partnership is subject to extensive federal, state and local environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and may require the Partnership to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a noncapital nature are recorded when environmental assessment and/or remediation is probable, and the costs can be reasonably estimated. Such liabilities are generally undiscounted unless the timing of cash payments for the liability or component are fixed or reliably determinable. No such liabilities have been accrued as of December 31, 1998. Revenue recognition -- The Partnership uses the entitlements method of accounting for crude oil and natural gas revenues. Reporting comprehensive income -- Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130") establishes standards for the reporting and display of comprehensive income (loss) and its components in a full set of general purpose financial statements. Comprehensive income (loss) includes net income (loss) and other comprehensive income (loss). The Partnership has no items of other comprehensive income (loss), as defined by SFAS No. 130. Consequently, the provisions of SFAS No. 130 do not apply to the Partnership. NOTE 3. IMPAIRMENT OF LONG-LIVED ASSETS In accordance with SFAS 121, the Partnership reviews its proved oil and gas properties for impairment whenever events and circumstances indicate a decline in the recoverability of the carrying value of the Partnership's oil and gas properties. Based upon a decline in the Partnership's outlook for future commodity prices, the Partnership has estimated the expected future cash flows of its oil and gas properties as of December 31, 1998, 1997 and 1996, and compared such estimated future cash flows to the respective carrying amount of the oil and gas properties to determine if the carrying amounts were likely to be recoverable. For those proved oil and gas properties for which the carrying amount exceeded the estimated future cash flows, an impairment was determined to exist; therefore, the Partnership adjusted the carrying amount of those oil and gas properties to their fair value as determined by discounting their expected future cash flows at a discount rate commensurate with the risks involved in the industry. As a result, the Partnership recognized non-cash impairment provisions of $405,308 and $699,976 related to its proved oil and gas properties during 1998 and 1997, respectively. 16 152 PARKER & PARSLEY 88-A, L.P.

OIL AND GAS INFORMATION (UNAUDITED) The following table presents information relating to the Partnership's estimated proved oil and gas reserves at December 31, 1998, 1997 and 1996 and changes in such quantities during the years then ended. Due to a change in the accounting policy of the managing general partner in 1997, the Partnership began accounting for processed natural gas production in two components: processed natural gas liquids ("NGLs") and dry residue gas. NGLs are reflected in "Oil and NGLs" in the table below. All of the Partnership's reserves are proved developed and located within the United States. The Partnership's reserves are based on an evaluation prepared by the engineering staff of Pioneer USA and reviewed by Williamson Petroleum Consultants, Inc., an independent petroleum consultant, using criteria established by the Securities and Exchange Commission. Reserve value information is available to limited partners pursuant to the Partnership agreement and, therefore, is not presented. OIL AND NGLS GAS (BBLS) (MCF) ------------ ---------- Net proved reserves at January 1, 1996...................... 659,108 2,318,253 Revisions................................................... 84,526 591,597 Production..................................................

(57,635) (86,501) -------- ---------- Net proved reserves at December 31, 1998.................... 471,675 851,238 ======== ========== As of December 31, 1998, the estimated present value of future net revenues of proved reserves, calculated using December 31, 1998 prices of $10.61 per barrel of oil, $5.47 per barrel of NGLs and $1.39 per mcf of gas, discounted at 10% was approximately $896,000 and undiscounted was $1,446,000. Numerous uncertainties exist in estimating quantities of proved reserves and future net revenues therefrom. The estimates of proved reserves and related future net revenues set forth in this report are 18 154 PARKER & PARSLEY 88-A, L.P. (A DELAWARE LIMITED PARTNERSHIP) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) based on various assumptions, which may ultimately prove to be inaccurate. Therefore, such estimates should not be construed as estimates of the current market value of the Partnership's proved reserves. The Partnership emphasizes that reserve estimates are inherently imprecise and, accordingly, the estimates are expected to change as future information becomes available. NOTE 8. MAJOR CUSTOMERS The following table reflects the major customers of the Partnership's oil and gas sales (a major customer is defined as a customer whose sales exceed 10% of total sales) during the years ended December 31: 1998 1997 1996 ---- ---- ---- Genesis Crude Oil, L.P. .................................... 55% 55% 59% Western Gas Resources, Inc. ................................ 22% 22% 19% At December 31, 1998, the amounts receivable from Genesis Crude Oil, L.P. and Western Gas Resources, Inc. were $21,404 and $22,658, respectively, which are included in the caption "Accounts receivable -- oil and gas sales" in the accompanying Balance Sheet. The Partnership's share of oil and gas production is sold to various purchasers. Pioneer USA is of the opinion that the loss of any one purchaser would not have an adverse effect on the ability of the Partnership to sell its oil and gas production. NOTE 9. ORGANIZATION AND OPERATIONS The Partnership was organized June 30, 1988 as a limited partnership under the Delaware Act for the purpose of acquiring and developing oil and gas properties. The following is a brief summary of the more significant provisions of the limited partnership agreement: Managing general partner -- The managing general partner of the Partnership is Pioneer USA. Pioneer USA has the power and authority to manage, control and administer all Program and Partnership affairs. As managing general partner and operator of the Partnership's properties, all production expenses are incurred by Pioneer USA and billed to the Partnership and a portion of revenue is initially received by Pioneer USA prior to being paid to the Partnership. Under the limited partnership agreement, the managing general partner pays 1% of the Partnership's acquisition, drilling and completion costs and 1% of its operating and general and administrative expenses. In return, it is allocated 1% of the Partnership's revenues. Limited partner liability -- The maximum amount of liability of any limited partner is the total contributions of such partner plus his share of any undistributed profits. Initial capital contributions -- The limited partners entered into subscription agreements for aggregate capital contributions of $12,935,000. Pioneer USA is required to contribute amounts equal to 1% of initial Partnership capital less commission and offering expenses allocated to the limited partners and to contribute amounts necessary to pay costs and expenses allocated to it under the Partnership agreement to the extent its share of revenues does not cover such costs. 19 155 ITEM 9.

(A DELAWARE LIMITED PARTNERSHIP) DECEMBER 31, 1998, 1997 AND 1996 STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS The standardized measure of discounted future net cash flows is computed by applying year-end prices of oil and gas (with consideration of price changes only to the extent provided by contractual arrangements) to the estimated future production of proved oil and gas reserves less estimated future expenditures (based on year-end costs) to be incurred in developing and producing the proved reserves, discounted using a rate of 10% per year to reflect the estimated timing of the future cash flows. Future income taxes are calculated by comparing discounted future cash flows to the tax basis of oil and gas properties plus available carryforwards and credits and applying the current tax rates to the difference. Discounted future cash flow estimates like those shown below are not intended to represent estimates of the fair value of oil and gas properties. Estimates of fair value should also consider probable reserves, anticipated future oil and gas prices, interest rates, changes in development and production costs and risks associated with future production. Because of these and other considerations, any estimate of fair value is necessarily subjective and imprecise.
