Mesa Petroleum Co. was the predecessor to Mesa Limited Partnership ("MLP"), the predecessor to MESA Inc. On April 30, 1991, MLP sold its interests in the Royalty Properties located in the San Juan Basin field to Conoco Inc. ("Conoco"), a wholly owned subsidiary of E. I. duPont de Nemours & Company. Conoco sold the portion of its interests in the San Juan Basin Royalty Properties located in Colorado to MarkWest Energy Partners, Ltd. (effective January 1, 1993) and Red Willow Production Company (effective April 1, 1992). On October 26, 1994, MarkWest Energy Partners, Ltd. sold substantially all of its interest in the Colorado San Juan Basin Royalty Properties to Amoco Production Company ("Amoco"), a subsidiary of Amoco Corp. Until August 7, 1997, MESA Inc. operated the Hugoton Royalty Properties through Mesa Operating Co. ("Mesa"), a subsidiary of MESA Inc. 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, the Hugoton Royalty Properties have been operated by PNR. The San Juan Basin Royalty Properties located in New Mexico are operated by Conoco. The San Juan Basin Royalty Properties located in Colorado are operated by Amoco. As used in this report, PNR refers to the operator of the Hugoton Royalty Properties, Conoco refers to the operator of the San Juan Basin Royalty Properties, other than the portion of such properties located in Colorado, and Amoco refers to the operator of the Colorado San Juan Basin Royalty Properties unless otherwise indicated. The terms "working interest owner" and "working interest owners" generally refer to the operators of the Royalty Properties as described above, unless the context in which such terms are used indicates otherwise. NOTE 2 -- BASIS OF PRESENTATION The accompanying unaudited financial information has been prepared by Chase Bank of Texas, National Association ("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. The Mesa Royalty Trust Indenture was amended in 1985, the effect of which was an overall reduction of approximately 88.56% in the size of the Trust; therefore, the Trust is now entitled each month to receive 90% of 11.44% of the net proceeds for the preceding month. Generally, net proceeds means the excess of the amounts received by the working interest owners from sales of oil and gas from the Royalty Properties over operating and capital costs incurred. 3 The financial statements of the Trust are prepared on the following basis: (a) Royalty income recorded for a month is the amount computed and paid by the working interest owners to the Trustee for such month rather than either the value of a portion of the oil and gas produced by the working interest owners for such month or the amount subsequently determined to be the Trust's proportionate share 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's date through the next distribution date; (c) Trust general and administrative expenses, net of reimbursements, are recorded in the month they accrue; (d) Amortization of the net overriding royalty interests, which is calculated on a unit-of-production basis, 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 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 thought 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 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. 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" are forward-looking statements. Although the Working Interest Owners have advised the Trust that they believe that the expectations reflected in the forward-looking statements contained herein 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 and in the Trust's Form 10-K, 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 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 utilizes 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 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 application 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. 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 5 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 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. Conoco has completed the inventory and assessment phases and has entered the remediation and testing phases of its plan to become Year 2000-capable. Approximately 98 percent of the work required to fix issues identified by the Year 2000 Program has been completed as of September 30, 1999. All mission critical work for Conoco's operations is complete. However, Conoco cannot reasonably estimate the potential impact on its financial condition and operations if key third parties, including governments, do not become Year 2000-capable on a timely basis. Conoco is working through various trade associations as well as communicating directly with its significant suppliers and customers to determine their Year 2000 capability. In addition, Conoco has begun contingency planning to handle potential disruptions in electrical, telecommunications, transportation and distribution services. There can be no guarantee that these efforts will prevent the failure of third parties to become Year 2000-capable and from having a material adverse affect on Conoco's financial condition or operations or the Royalty Properties operated by Conoco. None of Conoco's costs related to the Year 2000 are passed through to the Trust. 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. The information above with respect to PNR and Conoco is based on information provided by PNR and Conoco to the Trustee for use in this Form 10-Q. 6 SUMMARY OF ROYALTY INCOME AND AVERAGE PRICES (UNAUDITED) Royalty income is computed after deducting the Trust's proportionate share of capital costs, operating costs and interest on any cost carryforward from the Trust's proportionate share of "Gross Proceeds," as defined in the Royalty conveyance. The following unaudited summary illustrates the net effect of the components of the actual Royalty computation for the periods indicated.

(2) Capital costs recovered represents capital costs incurred during the current or prior periods to the extent that such costs have been recovered by the working interest owners from current period Gross Proceeds. Cost carryforward represents capital costs incurred during the current or prior periods which will be recovered from future period Gross Proceeds. The cost carryforward resulting from the Fruitland Coal drilling program was $479,365 and $481,350 at September 30, 1999 and September 30, 1998, respectively. The cost carryforward at September 30, 1999 and September 30, 1998 relate solely to the San Juan Basin Colorado properties. 7 THREE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998 The distributable income of the Trust includes the Royalty income received from the working interest owners during such period, plus interest income earned to the date of distribution. Trust administration expenses are deducted in the computation of distributable income. Distributable income for the quarter ended September 30, 1999 was $1,400,089, representing $.7513 per unit, compared to $1,412,663, representing $.7580 per unit, for the quarter ended September 30, 1998. Based on 1,863,590 units outstanding for the quarters ended September 30, 1999 and 1998, respectively, the per unit distributions were as follows: 1999 1998 --------- --------- July........................... $ .2317 $ .2808 August......................... .2781 .2525 September...................... .2414 .2247 --------- --------- $ .7513 $ .7580 ========= ========= HUGOTON FIELD PNR has advised the Trust that since June 1, 1995 natural gas produced from the Hugoton field has generally been sold under short-term contracts at market clearing prices to multiple purchasers including Williams Energy Supply ("WESCO"), OnEok Gas Marketing Inc., Amoco Production Company, and Anadarko Energy Services, Inc. PNR has advised the Trust that it expects to continue to market gas production from the Hugoton field under short-term and multi-month contracts. Overall market prices received for natural gas from the Hugoton Royalty Properties were higher in the third quarter of 1999 compared to the third quarter of 1998. PNR is currently a party to a Gas Transportation Agreement with Mid Continent Market Center ("Midcontinent") that was assigned to Midcontinent by Western Resources, Inc. in 1998. The Gas Transportation Agreement will terminate June 1, 2000 unless continued in effect year to year thereafter. Pursuant to the Gas Transportation Agreement, Midcontinent agrees to compress and transport up to 160 MMcf per day of gas and redeliver such gas to PNR at the inlet of PNR's Satanta Plant, and PNR agrees to pay Midcontinent a fee of $0.06 per Mcf escalated 4% annually as of June 1, 1996. Royalty income attributable to the Hugoton Royalty decreased to $882,587 in the third quarter of 1999, as compared to $972,768 in the third quarter of 1998 primarily due to lower natural gas and natural gas liquids production volumes. The average price received in the third quarter of 1999 for natural gas and natural gas liquids sold from the Hugoton field was $1.99 per Mcf and $10.76 per barrel, respectively, compared to $1.95 per Mcf and $9.21 per barrel during the same period in 1998. In addition, net production attributable to the Hugoton Royalty was 322,744 Mcf of natural gas and 22,335 barrels of natural gas liquids in the third quarter of 1999 compared to 391,347 Mcf of natural gas and 22,762 barrels of natural gas liquids in the third quarter of 1998. Allowable rates of production in the Hugoton field are set by the Kansas Corporation Commission (the "KCC") based on the level of market demand. The KCC set the Hugoton field allowable for the period April 1, 1999 through September 30, 1999, at 184.6 billion cubic feet of gas, compared with 214.6 billion cubic feet of gas during the same period last year. In addition, the KCC has set the Hugoton field allowable for the period October 1, 1999 through March 31, 2000, at 179.6 billion cubic feet of gas. SAN JUAN BASIN Royalty income from the San Juan Basin Royalty Properties is calculated and paid to the Trust on a state-by-state basis. The Royalty income from the San Juan Basin Royalty Properties located in the state of New Mexico increased to $494,212 during the third quarter of 1999 as compared with 8 $427,588 in the third quarter of 1998 due to higher average natural gas and natural gas liquids prices and higher natural gas production. No Royalty income was received from the San Juan Basin Royalty Properties located in Colorado for the second quarter of 1999 or 1998, as costs associated with the Fruitland Coal drilling on such properties have not been fully recovered. Net production attributable to the San Juan Basin Royalty was 197,796 Mcf of natural gas and 8,764 barrels of natural gas liquids in the third quarter of 1999 as compared to 187,495 Mcf of natural gas and 8,956 barrels of natural gas liquids in the third quarter of 1998. The average price received in the third quarter of 1999 for natural gas sold from the San Juan Basin was $1.90 per Mcf, compared to $1.80 per Mcf during the same period in 1998. The Trust's interest in the San Juan Basin was conveyed from PNR's working interest in 31,328 net producing acres in northwestern New Mexico and southwestern Colorado. The San Juan Basin New Mexico reserves represent approximately 36% of the Trust's reserves. PNR completed the sale of its underlying interest in the San Juan Basin Royalty Properties to Conoco on April 30, 1991. Conoco subsequently sold its underlying interest in the Colorado portion of the San Juan Basin Royalty Properties to MarkWest Energy Partners, Ltd. (effective January 1, 1993) and Red Willow Production Company (effective April 1, 1992). On October 26, 1994, MarkWest Energy Partners, Ltd. sold substantially all of its interest in the Colorado San Juan Basin Royalty Properties to Amoco. The San Juan Basin Royalty Properties located in Colorado account for less than 5% of the Trust's reserves. NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998 Distributable income decreased to $3,819,210 for the nine months ended September 30, 1999 from $5,235,250 for the same period in 1998. HUGOTON FIELD Royalty income attributable to the Hugoton Royalty Properties decreased to $2,362,109 for the nine months ended September 30, 1999 from $3,590,809 for the same period in 1998 due to lower natural gas and natural gas liquids production and as well as lower average prices. The average price received in the first nine months of 1999 for natural gas sold from the Hugoton field was $1.83 per Mcf, compared to $2.18 per Mcf during the same period in 1998. SAN JUAN BASIN Royalty income attributable to the New Mexico San Juan Basin Royalty Properties decreased to $1,429,930 for the first nine months of 1999 compared to $1,612,892 in the first nine months of 1998 as a result of decreased average natural gas and natural gas liquids prices. The average price received in the first nine months of 1999 for natural gas sold from the San Juan Basin was $1.71 per Mcf, compared to $2.00 per Mcf during the same period in 1998. No Royalty income was received from San Juan Basin Royalty Properties located in Colorado for the nine months ended September 30, 1999 and 1998, as costs associated with Fruitland Coal drilling on such properties have not been fully recovered. The gas that is currently being produced from the San Juan Basin Royalty Properties is being sold primarily on the spot market. No distributions related to the Colorado portion of the San Juan Basin Royalty have been made since 1990, as the costs of the Fruitland Coal drilling in Colorado have not yet been recovered. The San Juan Basin development drilling program has no effect on Royalty income or distributions relating to the Hugoton Royalty. Conoco has informed the Trust that it believes the production from the Fruitland Coal formation will generally qualify for the tax credits provided under Section 29 of the Internal Revenue Code of 1986, as amended. Thus, unitholders are potentially eligible to claim their share of the tax credit attributable to this qualifying production. Each unitholder should consult his tax advisor regarding the limitations and requirements for claiming this tax credit. 9 PART II -- OTHER INFORMATION ITEM 6.
