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 wholly owned 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 are 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 Texas Commerce Bank 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 1996 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 MESA ROYALTY TRUST NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (UNAUDITED) 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 from the balance sheet date through the next distribution date; (c) Trust general and administration 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, 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. On August 7, 1997, MESA Inc. and Parker & Parsley Petroleum Company merged to create Pioneer Natural Resources Company, one of the largest independent oil and gas exploration and production company in the United States. Pioneer has advised the Trust that this merger should have no significant effects on the Trust, although the precise nature of any effects cannot be predicted or quantified at this time. 5 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 $464,570 and $467,784 at September 30, 1997 and September 30, 1996, respectively. The cost carryforward at September 30, 1997 and September 30, 1996 relate solely to the San Juan Basin Colorado properties. 6 THREE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996 The distributable income of the Trust for a period 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, 1997 was $1,704,494, representing $.9146 per unit, compared to $1,842,649, representing $.9887 per unit, in the third quarter of 1996. Based on 1,863,590 units outstanding for the quarters ended September 30, 1997 and 1996, respectively, the per unit distributions were as follows: 1997 1996 --------- --------- July................................. $ .3012 $ .3361 August............................... .3156 .3153 September............................ .2978 .3373 --------- --------- $ .9146 $ .9887 ========= ========= 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 Western Resources, Inc. ("WRI"), Westar Gas Marketing, Inc., Missouri Gas Energy, Amoco and Noram Energy Services, Inc. PNR expects to continue to market gas production from the Hugoton field under short-term and multi-month contracts. In June 1994, PNR entered into a Gas Transportation Agreement with WRI ("Gas Transportation Agreement") for a primary term of five years commencing June 1, 1995 and ending June 1, 2000, but which may be continued in effect year-to-year thereafter. Pursuant to the Gas Transportation Agreement, WRI agreed to compress and transport up to 160 MMcf per day of gas and redeliver such gas to PNR at the inlet of PNR's Santanta Plant. PNR agreed to pay WRI a fee of $0.06 per Mcf escalating 4% annually as of June 1, 1996. Royalty income attributable to the Hugoton Royalty decreased to $1,158,353 in the third quarter of 1997 as compared to $1,526,343 in the third quarter of 1996 primarily due to lower natural gas prices coupled with increased 1996 production from compression added in 1995 in the Hugoton field. Production in 1996 was higher because of this added compression and is now declining naturally. The average price received in the third quarter of 1997 for natural gas sold from the Hugoton Royalty properties was $1.94 per Mcf, compared to $2.04 per Mcf during the same period in 1996. Net production attributable to the Hugoton Royalty was 391,305 Mcf of natural gas and 31,509 barrels of natural gas liquids in the third quarter of 1997 as compared to 509,103 Mcf of natural gas and 37,321 barrels of natural gas liquids in the third quarter of 1996. The decrease in natural gas production was attributable to higher than normal rates in 1996 resulting from the added compression. 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 has set the Hugoton field allowable for the period October 1, 1997 through March 31, 1998, at 222 billion cubic feet of gas, compared with 232 billion cubic feet of gas during the same period last year. 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 New Mexico was $539,983 during the third quarter of 1997 as compared with $336,152 in the third quarter 7 of 1996. The increase in San Juan Basin royalty income between the third quarter of 1997 and the third quarter of 1996 was primarily a result of higher natural gas prices. The average price received in the third quarter of 1997 for natural gas sold from the San Juan Basin Royalty Properties was $1.85 per Mcf, compared to $1.23 per Mcf during the same period in 1996. Net production attributable to the San Juan Basin Royalty was 229,011 Mcf of natural gas and 9,179 barrels of natural gas liquids in the third quarter of 1997 compared to 176,699 Mcf of natural gas and 8,483 barrels of natural gas liquids in the third quarter of 1996. No royalty income was received from the San Juan Basin Royalty Properties located in Colorado for the third quarter of 1997 or 1996, as costs associated with the Fruitland Coal drilling on such properties have not been fully recovered. The Trust's interest in the San Juan Basin Royalty Properties was conveyed from Mesa'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 35% 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 interests in the Colorado San Juan Basin Royalty Properties to Amoco. The San Juan Basin Royalty Properties located in Colorado account for approximately 5% of the Trust's reserves. NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996 Distributable income increased to $7,254,437 for the nine months ended September 30, 1997 as compared to $6,127,971 for the same period in 1996 due primarily to higher natural gas prices. HUGOTON FIELD Royalty income attributable to the Hugoton Royalty Properties decreased to $4,688,341 for the nine months ended September 30, 1997, from $5,082,668 for the same period in 1996 primarily due to lower production partially offset by higher natural gas prices. The average price received in the first nine months of 1997 for natural gas sold from the Hugoton Royalty Properties increased to $2.43 per Mcf, compared to $2.10 per Mcf during the same period in 1996. In addition, net production attributable to the Hugoton Royalty Properties decreased to 1,295,554 Mcf of natural gas and 97,663 barrels of natural gas liquids in the first nine months of 1997 compared to 1,693,765 Mcf of natural gas and 121,976 barrels of natural gas liquids in the first nine months of 1996. SAN JUAN BASIN Royalty income attributable to the New Mexico San Juan Basin Royalty Properties increased to $2,521,825 for the first nine months of 1997 from $1,038,140 in royalty income in the first nine months of 1996 primarily as a result of increased natural gas production. Net production attributable to the San Juan Basin Royalty Properties was 927,404 Mcf of natural gas and 30,196 barrels of natural gas liquids in the first nine months of 1997 compared to 539,426 Mcf of natural gas and 27,931 barrels of natural gas liquids in the first nine months of 1996. The average price received in the first nine months of 1997 for natural gas sold from the San Juan Basin Royalty Properties was $2.21 per Mcf, compared to $1.24 per Mcf during the same period in 1996. No royalty income was received from the Colorado San Juan Basin Royalty Properties for the first nine months of 1997 or 1996, as costs associated with Fruitland Coal drilling on such properties have not been fully recovered. 8 The gas that is currently being produced from the San Juan Basin Royalty Properties is being sold primarily on the spot market. Conoco has advised the Trust that it will also consider selling some of the gas produced from these wells pursuant to longer term contracts at spot market prices. 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.
