Note 1—Trust Organization

        The Mesa Royalty Trust (the "Trust") was created on November 1, 1979 when Mesa Petroleum Co. conveyed to the Trust a 90% net profits overriding royalty interest (the "Royalty") in certain producing oil and gas properties located in the Hugoton field of Kansas, the San Juan Basin field of New Mexico and Colorado and the Yellow Creek field of Wyoming (collectively, the "Royalty Properties"). 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"). 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 BP Amoco. Until August 7, 1997, MESA Inc. operated the Hugoton Royalty Properties through Mesa Operating Co., 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 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 JPMorgan Chase Bank ("Trustee"), in accordance with the instructions to Form 10-Q. JPMorgan Chase Bank was formerly known as The Chase Manhattan Bank and is the successor by mergers to the original name of the Trustee, Texas Commerce Bank National Association. 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 2001 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

3

the amounts received by the working interest owners from sales of oil and gas from the Royalty Properties over operating and capital costs incurred.

        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 date through the next date of distribution and;

        (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, it will differ from the basis used for financial statements prepared in accordance with accounting principles accepted in the United States of America. Under these accounting 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 for a month would be calculated only through the end of such month.

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 under the section "Business—Principal Trust Risk Factors". 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.

SUMMARY OF ROYALTY INCOME AND AVERAGE PRICES

        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:

5

(1)

Gross Proceeds from natural gas liquids attributable to the Hugoton and San Juan Basin Properties are net of a volumetric in-kind processing fee retained by PNR and Conoco, respectively.

(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 $304,208 and $406,612 at June 30, 2002 and June 30, 2001, respectively. The cost carryforward at June 30, 2002 and June 30, 2001 relate solely to the San Juan Basin Colorado properties.

Three Months Ended June 30, 2002 and 2001

        The distributable income of the Trust for each 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 June 30, 2002 was $1,081,100, representing $.5801 per unit, compared to $3,547,180, representing $1.9034 per unit, for the quarter ended June 30, 2001. Based on 1,863,590 units outstanding for the quarters ended June 30, 2002 and 2001, respectively, the per unit distributions were as follows:

6

Hugoton Field

        Natural gas and natural gas liquids from the Hugoton field and attributable to the Royalty accounted for approximately 56% of the Royalty income of the Trust during the second quarter of 2002.

        PNR has advised the Trust that since June 1, 1995 natural gas produced from the Hugoton field has generally been sold under short-term and multi-month contracts at market clearing prices to multiple purchasers including Williams Energy Supply ("WESCO"), Oneok Gas Marketing Inc., Amoco, 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 significantly lower in the second quarter of 2002 compared to the second quarter of 2001.

        In June 1994, PNR entered into a Gas Transportation Agreement ("Gas Transportation Agreement") with Western Resources, Inc. ("WRI") for a primary term of five years commencing June 1, 1995. This contract has been continued in effect on a year-to-year basis since June 1, 2000. PNR has extended the contract to June 1, 2003. Pursuant to the Gas Transportation Agreement, WRI has 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 Satanta Plant. PNR agreed to pay WRI a fee of $0.06 per Mcf escalating 4% annually as of June 1, 1996. This Gas Transportation Agreement has been assigned to Midcontinent Market Center.

        Royalty income attributable to the Hugoton Royalty decreased to $613,419 in the second quarter of 2002, as compared to $2,413,758 in the second quarter of 2001 primarily due to lower prices received for production of natural gas and natural gas liquids from the Hugoton Royalty Properties and lower natural gas production volumes. The average price received in the second quarter of 2002 for natural gas and natural gas liquids sold from the Hugoton Royalty Properties was $2.25 per Mcf and $11.94 per barrel, respectively, compared to $6.19 per Mcf and $24.99 per barrel during the same period in 2001. Net production attributable to the Hugoton Royalty was 193,256 Mcf of natural gas and 14,958 barrels of natural gas liquids in the second quarter of 2002 compared to 323,993 Mcf of natural gas and 16,336 barrels of natural gas liquids in the second quarter of 2001.

        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 April 1, 2002 through September 30, 2002, at 141.4 Bcf of gas, compared with 156.2 Bcf 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. Royalty income from the San Juan Basin Royalty Properties located in the state of New Mexico was $477,766 during the second quarter of 2002 as compared with $1,113,460 in the second quarter of 2001. The decrease in Royalty income was due primarily to decreased natural gas and natural gas liquids prices in the second quarter of 2002 as compared to the second quarter of 2001. No Royalty income was received from Amoco with respect to the San Juan Basin Royalty Properties located in the state of Colorado for the second quarter of 2002 or 2001, as costs associated with the Fruitland Coal drilling program on such properties have not been fully recovered. Net production attributable to the San Juan Basin Royalty was 124,198 Mcf of natural gas and 11,550 barrels of natural gas liquids in the second quarter of 2002 as compared to 190,754 of natural gas and 14,096 barrels of natural gas liquids in the second quarter of 2001. The average price received in the second quarter of 2002 for natural gas sold from

7

the San Juan Basin Royalty Properties was $2.33 per Mcf and $16.31 per barrel, respectively, compared to $4.45 per Mcf and $24.46 per barrel during the same period in 2001.

        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 52% of the Trust's reserves. Substantially all of the natural gas produced from the San Juan Basin is currently being sold on the spot market. The San Juan Basin Royalty Properties located in Colorado account for less than 5% of the Trust's reserves.

        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.

        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. These tax credits will expire January 1, 2003 unless otherwise extended. Each unitholder should consult his tax advisor regarding the limitations and requirements for claiming this tax credit.

Six Months Ended June 30, 2002 and 2001

        Distributable income decreased to $1,974,030 for the six months ended June 30, 2002 from $7,415,385 for the same period in 2001.

Hugoton Field

        Royalty income attributable to the Hugoton Royalty Properties decreased to $1,269,525 for the six months ended June 30, 2002 from $4,437,048 for the same period in 2001 primarily due to lower natural gas and natural gas liquid average prices received and lower natural gas production volumes. The average price received in the first six months of 2002 for natural gas and natural gas liquids sold from the Hugoton field was $2.29 per Mcf and $12.87 per barrel, compared to $5.82 per Mcf and $24.93 per barrel during the same period in 2001.

San Juan Basin

        Royalty income attributable to the New Mexico San Juan Basin Royalty Properties decreased to $724,664 for the first six months of 2002 compared to $2,920,186 in the first six months of 2001. The average price received in the first six months of 2002 for natural gas sold from the San Juan Basin was $2.41 per Mcf, compared to $5.00 per Mcf during the same period in 2001. No Royalty income was received from San Juan Basin Royalty Properties located in Colorado for the six months ended June 30, 2002 and 2001, as costs associated with Fruitland Coal drilling on such properties have not been fully recovered.
