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 and the managing general partner of the Royalty Properties. 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 In 1996, PNR drilled five wells from the existing "A" platform on the South Marsh Island 155 block. PNR recovered all remaining costs related to the South Marsh Island drilling program as of the February 1997 reporting month. In addition, during the first quarter of 1997, the Trust recovered approximately $.5 million in general and administrative expenses paid from the Trust's reserve fund during the period in which Royalty income was not paid to the Trust, replenishing the Trust's expense reserve fund balance to $2 million. 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 December 31, 1997 reserve report prepared for the Partnership (see the Trust's 1997 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 1998 the Trust may commence a period of three successive years in which annual net royalty income would be below the termination threshold prescribed in the Indenture, resulting in termination of the Trust pursuant to the terms discussed above. 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 1997 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 accrue; (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. 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, it will differ from the basis used for 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 be calculated only for the periods 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. 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. 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. INFORMATION SYSTEMS FOR THE YEAR 2000 Pioneer has established a "Year 2000" project (the "Project") to assess, to the extent possible, its Year 2000 risk exposure; to take remedial actions necessary to minimize the Year 2000 risk exposure to Pioneer and third parties with whom it has data interchange; and, to test its systems and processes once remedial actions have been taken. Because of the importance of occurrence dates in the oil and gas industry, the consequences of not pursuing Year 2000 modifications could be critical to Pioneer's ability to manage and report operating activities. Pioneer has contracted with a third party to perform the assessment and remedial phases of its Year 2000 project. The assessment phase of the Project is 85% complete as of September 30, 1998, and included, among other procedures, the assessment of information technology applications and systems, the assessment of non-information technology exposures; the initiation of inquiry and dialogue with significant third party business partners, customers and suppliers in an effort to understand their Year 2000 readiness and potential impact on Pioneer; and the formulation of contingency plans for mission-critical information technology systems. Pioneer 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 to inquiries made of third party businesses. The remedial phase of the Project is approximately 40% complete as of September 30, 1998, subject to the results of third party inquiry assessments and the testing phase. The remediation of non-information technology is expected to be completed by mid-1999. The testing phase of the Project is expected to be completed by May 1999 for information technology systems and by mid-1999 for non-information technology. Although Pioneer is making every effort to mitigate the risks associated with the Year 2000 problem, there can be no assurance that the Project or resulting contingency plans will have anticipated all Year 2000 scenarios. A failure to remedy a critical Year 2000 problem could result in information and non-information technology 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. Chase Bank of Texas, National Association ("Chase" or 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, Chase intends to have such systems and applications capable of processing, on and after January 1, 2000, date, and date-related data consistent with the 5 functionality of such systems and applications, without a material adverse effect upon its performance of services as Trustee. FINANCIAL REVIEW During the third quarter of 1998, the Trust had distributable income of $503,274, representing $.0070 per unit, as compared to $1,572,995, representing $.0219 per unit in the third quarter of 1997. The per unit amounts of distributable income for the third quarter of 1998 and 1997 were earned by month as follows: 1998 1997 --------- --------- July................................. $ .0010 $ .0074 August............................... .0019 .0080 September............................ .0041 .0065 --------- --------- $ .0070 $ .0219 ========= ========= Royalty income decreased to $535,215 in the third quarter of 1998 as compared to Royalty income for the third quarter of 1997. The decrease in Royalty income is primarily due to both reduced production and lower average sales prices for crude oil, condensate and natural gas liquids in the third quarter of 1998 when compared to the corresponding 1997 period. Production volumes for natural gas decreased to 359,001 Mcf in the third quarter of 1998 from 798,555 Mcf in the third quarter of 1997.The average price received for natural gas was $2.21 per Mcf in the third quarter of 1998 compared to $2.12 per Mcf in the third quarter of 1997. Crude oil, condensate and natural gas liquids production decreased to 25,153 barrels in the third quarter of 1998 from 40,870 barrels in the third quarter of 1997. The average price received for crude oil, condensate and natural gas liquids was $12.00 per barrel in the third quarter of 1998, compared to $14.05 per barrel in the third quarter of 1997. The decrease in natural gas and crude oil, condensate and natural gas liquids production for both the nine months and the quarter ended September 30, 1998 when compared to the comparable periods of 1997 are primarily attributable to the cessation of production on the A-6 ST and A-21 wells on South Marsh Island blocks 155 and 156 during late 1997 and natural production declines on the A-20, A-22 and A-14 ST wells as a result of pressure depletion and water encroachment. For the nine months ended September 30, 1998, natural gas production volumes decreased to 1,164,666 Mcf from 3,491,449 Mcf for the nine months ended September 30, 1997. Crude oil, condensate and natural gas liquids production volumes decreased to 49,593 barrels in the first nine months of 1998 as compared to 147,274 barrels in the first nine months of 1997. OPERATIONAL REVIEW PNR has advised the Trust that during the third quarter of 1998 its offshore gas production was marketed under short term contracts at spot market prices to multiple purchasers, including Columbia Energy Service and Enron Gas Marketing, and 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 1998 were generally lower than spot market prices in the third quarter of 1997. 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 6 activities of OPEC and other oil and gas producers, weather, storage levels, industrial growth, conservation measures, competition and other variables. The Brazos A-39 block experienced a decrease in natural gas production in the third quarter of 1998 as compared to the third quarter of 1997, primarily due to natural production decline. The Brazos A-7 block also experienced a decrease in natural gas production in the third quarter of 1998 compared to the third quarter of 1997, primarily due to natural production decline. 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 that was drilled in the second quarter of 1997. The No. 5 well encountered gas pay and was suspended pending completion operations. Production facilities were installed, and the No. 5 well commenced production late in the second quarter at a rate of approximately 10 MMcf per day. The combined completion and facility costs are expected to total $6.6 million ($594,000 net to the Trust). The South Marsh Island 155 and 156 blocks experienced a decrease in production in the third quarter of 1998 as compared to the third quarter 1997, primarily due to natural production decline, and the cessation of production in the A6 ST. Production for the block is currently 1.6 MMcf per day and 74 barrels of condensate per day as of November 1998. PNR purchased 3D 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 a decrease in production in the third quarter of 1998 as compared to the third quarter of 1997, primarily due to the cessation of production of PNR operated wells. These wells are currently uneconomic to produce. In portions of West Delta Block 62, 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 attributable to the Trust consists of a 7.5% overriding royalty interest. In West Delta Block 61, 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 second quarter which encountered 320 net feet of pay in 8 Miocene sands below a true vertical depth of 7,500 feet. The operator will drill two development wells beginning later this year or in early 1999. The Trust will receive an 11.25% overriding royalty interest in these wells. Matagorda Island 624 production decreased in the third quarter of 1998 as compared to the third quarter of 1997, primarily due to natural production decline. Gross production for the block is currently 2.2 MMcf per day and 32 barrels of condensate per day as of November 1998. PENDING SALE AGREEMENT In September 1998, PNR signed a purchase and sale agreement (the "Agreement") to sell certain oil and gas properties. Included with the properties to be sold are Trust properties. The sale is expected to close by December 31, 1998 and, at such time, the purchaser will become the operator of the properties. The consummation of this Agreement is primarily dependent upon the purchaser's successful ability to finance the purchase as well as certain other contingencies defined in the Agreement. As a result, there can be no assurance that the sale of any or all of these properties will be completed. In addition, if such a sale is consummated, the Trust has been advised that the sale should have no significant effects on the Trust, although the precise nature of any effects cannot be predicted or quantified at this time. 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 7 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 1997 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 $173,000, $123,000 and $149,000 for the years 1997, 1996, and 1995, respectively. The December 31, 1997, reserve report prepared for the Partnership (see the Trust's 1997 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 1998 the Trust may commence a period of three successive years in which annual net royalty income would be below the termination threshold prescribed in the Indenture, resulting in termination of the Trust pursuant to the terms discussed above. 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 cash held by the Trust after the payment of or provision for all liabilities of the Trust, and the Trust would be terminated. 8 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, 1998: Ninety percent of gross proceeds....................... $ 242,529 $ 697,366 $ (2,509) $158,565 $ 1,095,951 Less ninety percent of -- Operating expenditures.........
