The Partnership was created to receive and hold a 90% net overriding royalty interest (the "Royalty") in ten producing and nonproducing oil and gas properties located in federal waters offshore Louisiana and Texas (the "Royalty Properties"). Until August 7, 1997, MESA Inc. owned and operated its assets through Mesa Operating Co. ("Mesa"), the operator of the Royalty Properties. Mesa Operating Co. is also the managing general partner of the Partnership (the Managing General Partners). On August 7, 1997, MESA Inc. merged with and into Pioneer Natural Resources Company ("Pioneer") formerly a wholly owned subsidiary of MESA, Inc. and Parker & Parsley Petroleum Company merged with and into Pioneer Natural Resources USA, Inc. (successor to Mesa Operating Co.), a wholly owned subsidiary of Pioneer ("PNR") (collectively, the mergers are referred to herein as the "Merger"). Subsequent to the Merger, Pioneer owns and operates its assets through PNR and is also the managing general partner of the Partnership. As used in this report, the term PNR generally refers to the operator of the Royalty Properties, unless otherwise indicated. STATUS OF THE TRUST The Trust Indenture provides that the Trust will terminate if the total amount of cash per year received by the Trust falls below certain levels for each of three successive years (the "Termination Threshold"). The December 31, 1998 reserve report prepared for the Partnership (see the Trust's 1998 Annual Report on Form 10-K) indicates that Royalty income expected to be received by the Trust in 2000 could be at or near the Termination Threshold. The reserve report estimates that future Royalty income to the Trust is approximately $5.2 million (which excludes the $2.1 million of royalty income resulting from the release of the MMS royalty reserve discussed below) while the Termination Threshold for 1998 was approximately $1.4 million. It is therefore possible (depending on the timing of future production and drilling activities, market conditions, recoupment of unrecovered capital costs and other matters) that in 2000 Royalty income received by the Trust may be below the Termination Threshold. If Royalty income falls below the Termination Threshold for three successive years, the Trust would terminate. Upon termination of the Trust, the Trustee will sell for cash all the assets held in the Trust estate and make a final distribution to unitholders of any funds remaining after all Trust liabilities have been satisfied. There are numerous uncertainties inherent in estimating and projecting the quantity and value of proved reserves for the Trust properties as many of the Trust properties are nearing the end of their productive lives and are therefore subject to unforeseen changes in production rates. As such, there can be no assurance that Royalty income received by the Trust in 2000 or thereafter will be above the Termination Threshold. NOTE 2 -- BASIS OF PRESENTATION The accompanying unaudited financial information has been prepared by Chase Bank of Texas, National Association (the "Trustee") in accordance with the instructions to Form 10-Q, and the Trustee believes such information includes all the disclosures necessary to make the information presented not misleading. The information furnished reflects all adjustments which are, in the opinion of the Trustee, necessary for a fair presentation of the results for the interim periods presented. The financial information should be read in conjunction with the financial statements and notes thereto included in the Trust's 1998 Annual Report on Form 10-K. 3 The financial statements of the Trust are prepared on the following basis: (a) Royalty income recorded for a month is the Trust's interest in the amount computed and paid by PNR to the Partnership for such month rather than either the value of a portion of the oil and gas produced by PNR for such month or the amount subsequently determined to be 90% of the net proceeds for such month; (b) Interest income, interest receivable and distributions payable to unitholders include interest to be earned on short-term investments from the financial statement date through the next distribution date; (c) Trust general and administrative expenses are recorded in the month they are accrued; (d) Amortization of the net overriding royalty interest, which is calculated on the basis of current royalty income in relation to estimated future royalty income, is charged directly to trust corpus since such amount does not affect distributable income; and (e) Distributions payable are determined on a monthly basis and are payable to unitholders of record as of the last business day of each month or such any other day as the Trustee determines is required to comply with legal or stock exchange requirements. However, cash distributions are made quarterly in January, April, July and October, and include interest earned from the monthly record dates to the date of distribution. This basis for reporting Royalty income is considered to be the most meaningful because distributions to the unitholders for a month are based on net cash receipts for such month. However, these statements differ from financial statements prepared in accordance with generally accepted accounting principles in several respects. Under such principles, royalty income for a month would be based on net proceeds from production for such month without regard to when calculated or received and interest income would include interest earned during the period covered by the financial statements and would exclude interest from the period end to the date of distribution. The instruments conveying the Royalty provide that PNR will calculate and pay the Partnership each month an amount equal to 90% of the net proceeds for the preceding month. Generally, net proceeds means the excess of the amounts received by PNR from sales of oil and gas from the Royalty Properties plus other cash receipts over operating and capital costs incurred. NOTE 3 -- RELEASE OF MMS ROYALTY RESERVE During the mid-1980's, PNR withheld approximately $3.5 million ($3.1 million net to the Trust) as a reserve for potential liabilities for royalty claims made by the Mineral Management Service ("MMS"). The claims by the MMS included, among other things, disputed transportation allowances attributable to the Trust's South Marsh Island properties and payments received by PNR from purchasers as settlements under gas purchase contracts. During 1998, PNR settled all known claims with the MMS for $3.6 million ($3.2 million net to the Trust) which significantly reduced the amount in the reserve. The balance of the reserve, including accrued interest, was approximately $3.4 million ($3.1 million net to the Trust). In May 1999, PNR determined that this reserve was no longer necessary. Approximately $3.1 million was released to the Trust, subject to the recovery of an approximate $1.0 million cost carryforward, and included, net of amounts used to replenish the reserve for Trust expenses, in the second quarter of 1999 distribution. 4 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS NOTE REGARDING FORWARD-LOOKING STATEMENTS This Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts included in this Form 10-Q, including without limitation the statements under "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 1 to the financial statements of the Trust regarding the future net revenues of the Trust, are forward-looking statements. Although Pioneer has advised the Trust that it believes that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from expectations ("Cautionary Statements") are disclosed in this Form 10-Q, including without limitation in conjunction with the forward-looking statements included in this Form 10-Q and in the Trust's Form 10-K. All subsequent written and oral forward-looking statements attributable to the Trust or persons acting on its behalf are expressly qualified in their entirety by the Cautionary Statements. STATUS OF POTENTIAL SALE OF TRUST PROPERTIES On April 15, 1999, PNR announced the termination of the transaction contemplated by the April 1, 1999 Purchase and Sales Agreement between PNR and Costilla Energy, Inc. providing for the sale of certain oil and gas properties to Costilla. Included with the properties to be sold were PNR's interest in all of the Royalty properties. PNR has executed a contingency plan to remarket these properties. If such a sale is consummated, the Trust has been advised that there should be no significant impact on the Trust, although the precise nature of any effects cannot be predicted or quantified at this time. INFORMATION SYSTEMS FOR THE YEAR 2000 The inability of some computer programs and embedded computer chips to distinguish between the year 1900 and the year 2000 (the "Year 2000 problem") poses a serious threat of business disruption to any organization that utilized computer technology and computer chip technology in their business systems or equipment. In proactive response to the Year 2000 problem, PNR established a "Year 2000" project to assess, to the extent possible, PNR's internal Year 2000 problem; to take remedial actions necessary to minimize the Year 2000 risk exposure to PNR and significant third parties with whom it has data interchange; and, to test its systems and processes once remedial actions have been taken. PNR has contracted with IBM Global Services to perform the assessment and remedial phases of its Year 2000 project. As of September 30, 1999, the assessment phase of PNR's Year 2000 project is complete on a worldwide basis and has included, among other procedures, (1) the identification of necessary remediation, upgrade and/or replacement of existing information technology applications and systems; (2) the assessment of non-information technology exposures, such as telecommunications systems, security systems, elevators and process control equipment; (3) 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 PNR and its Year 2000 problem; (4) the implementation of processes designed to reduce the risk of reintroduction of Year 2000 problems into PNR's systems and business processes; and, (5) the formulation of contingency plans for mission-critical information technology systems. As of September 30, 1999, PNR estimates that the remedial phase is approximately 98% complete, on a worldwide basis, subject to the continuing evaluations of the responses from third party inquiries and the testing phase. The remedial phase has included the upgrade and/or replacement of certain applications and hardware systems. The remediation of non-information technology was completed in October 1999. PNR's Year 2000 remedial actions have not delayed other information technology projects or upgrades. The testing phase of PNR's Year 2000 project is expected to be completed by the end of November 1999. None of PNR's costs related to the Year 2000 are passed through to the Trust. 5 A failure to remedy a critical Year 2000 problem could have a materially adverse effect on PNR'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 to PNR that cannot be accurately assessed at this time. In the assessment phase of PNR's Year 2000 project, contingency plans were designed to mitigate the exposure 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. The Trustee has developed and is implementing a program to prepare its systems and applications for the Year 2000, including those used to render services to the Trust. In that connection, the Trustee intends to have such systems and applications capable of processing, on and after January 1, 2000 date, and date-related data consistent with the functionality of such systems and applications, without a material adverse effect upon its performance of services as Trustee. Third parties that the Trust conducts business with could be prone to Year 2000 problems that could not be assessed or detected by the Trust. The Trust is contacting the major third parties to determine whether they will be able to resolve, in a timely manner, any Year 2000 problems directly affecting the Trust and to inform them of the Trust's internal assessment of its Year 2000 review. Information above with respect to PNR is based upon information provided by PNR to the Trustee for use in this Form 10-Q. FINANCIAL REVIEW During the third quarter of 1999, the Trust had distributable income of $570,680, representing $.0079 per unit, as compared to $503,274, representing $.0070 per unit in the second quarter of 1998. The per unit amounts of distributable income for the second quarter of 1999 and 1998 were earned by month as follows: 1999 1998 --------- --------- July........................... $ -- $ .0010 August......................... -- .0019 September...................... .0079 .0041 --------- --------- $ .0079 $ .0070 ========= ========= Royalty income increased to $588,131 in the third quarter of 1999 as compared to $535,215 in the third quarter of 1998. The increase in Royalty income is primarily due to the increase in natural gas production from West Delta 61 and 62. See "Operational Review." The Trust will not make any additional distributions until it has recouped approximately $92,000 of expenses paid from its reserve for Trust expenses. Production volumes for natural gas increased to 392,036 Mcf in the third quarter of 1999 from 359,001 Mcf in the third quarter of 1998 primarily as a result of increased production on West Delta 61 and 62 and Brazos A-7 and A-39 partially offset by a decrease in production on South Marsh Island 155 and 156. The average price received for natural gas was $2.22 per Mcf in the third quarter of 1999 compared to $2.21 per Mcf in the third quarter of 1998. Crude oil, condensate and natural gas liquids production decreased to 10,028 barrels in the third quarter of 1999 from 25,153 barrels in the third quarter of 1998. The average price received for crude oil, condensate and natural gas liquids was $16.09 per barrel in the third quarter of 1999, compared to $12.00 per barrel in the third quarter of 1998. 6 The decrease in natural gas and crude oil, condensate and natural gas liquids production for the nine months ended September 30, 1999 when compared to the comparable periods of 1998 is primarily attributable to the cessation of production from the South Marsh Island blocks 155 and 156 in the fourth quarter of 1998. For the nine months ended September 30, 1999, natural gas production volumes decreased to 854,621 Mcf from 1,164,666 Mcf for the nine months ended September 30, 1998. Crude oil, condensate and natural gas liquids production volumes decreased to 18,030 barrels in the first nine months of 1999 as compared to 49,593 barrels in the first nine months of 1998. OPERATIONAL REVIEW During the mid-1980's, PNR withheld approximately $3.5 million ($3.1 million net to the Trust) as a reserve for potential liabilities for royalty claims made by the Mineral Management Service ("MMS"). The claims by the MMS included, among other things, disputed transportation allowances attributable to the Trust's South Marsh Island properties and payments received by PNR from purchasers as settlements under gas purchase contracts. During 1998, PNR settled all known claims with the MMS for $3.6 million ($3.2 million net to the Trust) which significantly reduced the amount in the reserve. The balance of the reserve, including accrued interest, was approximately $3.4 million ($3.1 million net to the Trust). In May 1999, PNR determined that this reserve was no longer necessary. Approximately $3.1 million was released to the Trust, subject to the recovery of an approximate $1.0 million cost carryforward, and included, net of amounts used to replenish the reserve for Trust expenses, in the second quarter of 1999 distribution. PNR has advised the Trust that during the third quarter of 1999 its offshore gas production was marketed under short term contracts at spot market prices primarily to H&N, Limited. PNR has further advised the Trust that it expects to continue to market its production under short term contracts for the foreseeable future. Spot market prices for natural gas in the third quarter of 1999 were lower than spot market prices in the third quarter of 1998. The amount of cash distributed by the Trust is dependent on, among other things, the sales prices and quantities of gas, crude oil, condensate and natural gas liquids produced from the Royalty Properties and the quantities sold. Substantial uncertainties exist with regard to future gas and oil prices, which are subject to fluctuations due to the regional supply and demand for natural gas and oil, production levels and other activities of OPEC and other oil and gas producers, weather, industrial growth, conservation measures, competition and other variables. The Brazos A-7 and A-39 block experienced an increase in production due to new production from a farmout agreement. PNR farmed out a portion of the Brazos A-7 block to another operator and participated at a 10% working interest in the completion of an exploratory gas well drilled in the second quarter of 1997. During the fourth quarter of 1998, PNR incurred $7.35 million ($661,000 net to the Trust) of completion costs for the Brazos A-7 No. 5 well. As of June 30, 1999, the cost carryforward resulting from the completion costs on the Brazos A-7 No. 5 well, other capital expenditures and over distributions by PNR were recovered. The No. 5 well commenced production late in the fourth quarter of 1998 and is currently producing at a rate of approximately 10 MMcf per day. The South Marsh Island 155 and 156 blocks experienced a decrease in production in the third quarter of 1999 as compared to the third quarter of 1998, primarily due to the cessation of production from the A-19 well in late 1998. This block is currently not producing, but a workover was performed in May 1999 to attempt to restore production. The workover was not successful and PNR is currently exploring several alternatives to attempt to restore production. A plan should be completed in the fourth quarter of 1999. In 1998, PNR purchased 3-D seismic data for the South Marsh Island 156 block at a cost of $300,000 ($189,000 net to the Trust). The data has been evaluated and PNR has no current plans for additional drilling. The West Delta 61 and 62 blocks experienced an increase in oil and in natural gas production in the third quarter of 1999 as compared to the third quarter of 1998 primarily due to new production from farmout agreements. In portions of West Delta block 61, the Trust is receiving Royalty income from this property pursuant to a farmout agreement with another operator. The interest in the farmout wells which is 7 attributable to the Trust, consists of a 7.5% net profits interest. In West Delta block 62, PNR farmed out portions of the block to another operator, retaining a 10% (9% net to the Trust) overriding royalty interest. A new well was drilled in the third quarter of 1998 which encountered 320 net feet of pay in eight Miocene sands below a true vertical depth of 7,500 feet. In the fourth quarter of 1998, the operator drilled one development well and one exploratory well. The development well encountered 250 net feet of pay in seven Miocene sands. The operator has elected to set a four-pile platform, and production began in the second quarter of 1999. The exploratory well tested a new fault block which was determined to be non-commercial. The exploratory well was subsequently plugged in the first quarter of 1999. The Trust will receive an 11.25% overriding royalty interest in these wells. The Trust began receiving revenues from these new wells in the third quarter of 1999. Matagorda Island 624 oil and natural gas production decreased in the third quarter of 1999 as compared to the third quarter of 1998, primarily due to natural production decline. Gross producing rate of the block was approximately .85 MMcf of gas and 10 barrels of condensate per day as of September 1999. TERMINATION OF THE TRUST The terms of the Mesa Offshore Trust Indenture provide that the Trust will terminate upon the first to occur of the following events: (1) the total amount of cash received per year by the Trust for each of three successive years commencing after December 31, 1987 is less than 10 times one-third of the total amount payable to the Trustee as compensation for such three year period or (2) a vote by the unitholders in favor of termination. Because the Trust will terminate in the event the total amount of cash received per year by the Trust falls below certain levels, it would be possible for the Trust to terminate even though some of the Royalty Properties continued to have remaining productive lives. For information regarding the estimated remaining life of each of the Royalty Properties and the estimated future net revenues of the Trust based on information provided by PNR, see the Trust's 1998 Annual Report on Form 10-K. Upon termination of the Trust, the Trustee will sell for cash all the assets held in the Trust estate and make a final distribution to unitholders of any funds remaining after all Trust liabilities have been satisfied. The discussion set forth above is qualified in its entirety by reference to the Trust Indenture itself, which is available upon request from the Trustee. Amounts paid to the Trustee as compensation were $128,000, $173,000 and $123,000 for the years 1998, 1997, and 1996, respectively. The December 31, 1998, reserve report prepared for the Partnership (see the Trust's 1998 Annual Report on Form 10-K) indicates that 95% of future net revenues will be received by the Trust during the next four years. As such, it is possible, depending on the timing of future production, market conditions, the success of future drilling activities, if any, and other matters, that in 2000 Royalty income received by the Trust may be below the Termination Threshold. If Royalty income falls below the Termination Threshold for three successive years, the Trust would terminate pursuant to the terms discussed above. There are numerous uncertainties inherent in estimating and projecting the quantity and value of proved reserves for the Trust properties as many of the Trust properties are nearing the end of their productive lives and are therefore subject to unforeseen changes in production rates. As such, there can be no assurance that Royalty income received by the Trust in 2000 will be above the Termination Threshold. The terms of the First Amended and Restated Articles of General Partnership of the Partnership provide that the Partnership shall dissolve upon the occurrence of any of the following: (a) December 31, 2030; (b) the election of the Trustee to dissolve the Partnership; (c) the termination of the Trust; (d) the bankruptcy of the Managing General Partner; or (e) the dissolution of the Managing General Partner or its election to dissolve the Partnership; provided that the Managing General Partner shall not elect to dissolve the Partnership so long as the Trustee remains the only other partner of the Partnership. In the event of a dissolution of the Partnership and a subsequent winding up and termination thereof, the assets of the Partnership (i.e., the Royalty interest) could either (i) be distributed in kind ratably to the Managing General Partner and the Trustee or (ii) be sold and the proceeds thereof distributed ratably to the Managing General Partner and the Trustee. In the event of a sale of the Royalty and a distribution of the cash proceeds to the Trustee, the Trustee would make a final distribution to unitholders of such cash proceeds plus any other 8 cash held by the Trust after the payment of or provision for all liabilities of the Trust, and the Trust would be terminated. The following tables provide summaries of the calculations of the net proceeds attributable to the Partnership's royalty interests (unaudited): SOUTH BRAZOS MARSH WEST MATAGORDA A-7 AND ISLAND 155 DELTA 61 ISLAND A-39 AND 156 AND 62 624 TOTAL --------- ----------- ---------- ---------- ----------- THREE MONTHS ENDED SEPTEMBER 30, 1999: Ninety percent of gross proceeds....................... $ 321,079 $ 11,081 $ 623,737 $ 76,797 $ 1,032,694 Less ninety percent of -- Operating expenditures.........
