<P><FONT SIZE=2><B>Note&nbsp;1&#151;Trust Organization  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Mesa Royalty Trust (the "Trust") was created on November&nbsp;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&nbsp;Inc. On April&nbsp;30, 1991, MLP sold its
interests in the Royalty Properties located in the San Juan Basin field to ConocoPhillips (successor by merger to Conoco,&nbsp;Inc.). ConocoPhillips sold most of its interests in the San Juan Basin
Royalty Properties located in Colorado to MarkWest Energy Partners,&nbsp;Ltd. (effective January&nbsp;1, 1993) and Red Willow Production Company (effective April&nbsp;1, 1992). On
October&nbsp;26, 1994, MarkWest Energy Partners,&nbsp;Ltd. sold substantially all of its interest in the Colorado San Juan Basin Royalty Properties to BP Amoco Company ("BP"), a subsidiary of BP
p.l.c. Until August&nbsp;7, 1997, MESA&nbsp;Inc. operated the Hugoton Royalty Properties through Mesa Operating Co., a wholly owned subsidiary of MESA&nbsp;Inc. On August&nbsp;7, 1997,
MESA&nbsp;Inc. merged with and into Pioneer Natural Resources Company ("Pioneer"), formerly a wholly owned subsidiary of MESA&nbsp;Inc., and Parker&nbsp;&amp; Parsley Petroleum Company merged with
and into Pioneer Natural Resources USA,&nbsp;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. All of the San Juan Basin Royalty Properties located in New Mexico and a few wells located in Southwest Colorado
near the New Mexico border, are operated by ConocoPhillips. Substantially all of the San Juan Basin Royalty Properties located in Colorado are operated by BP. As used in this report, PNR refers to the
operator of the Hugoton Royalty Properties, ConocoPhillips refers to the operator of the San Juan Basin Royalty Properties, other than the portion of such properties located in Colorado, and BP 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. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective
October&nbsp;2, 2006, the Bank of New York Trust Company, N.A. (the "Trustee") succeeded JPMorgan Chase Bank, N.A. as Trustee of the Trust. JPMorgan Chase Bank, N.A. was the
successor by mergers to the original name of the Trustee, Texas Commerce Bank National Association. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
terms of the Mesa Royalty Trust Indenture (the "Indenture") provide, among other things, that: </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;the

$250,000 per year or (ii)&nbsp;a vote by the unitholders in favor of termination. Upon termination of the Trust, the Trustee will sell for cash all the assets held in the Trust estate and make a

ConocoPhillips and BP (collectively the "Working Interest Owners") will reimburse the Trust for 59.34%, 27.45% and 1.77%, respectively, for general and
administrative expenses of the Trust. </FONT></P>

</UL>

<P><FONT SIZE=2><B>Note&nbsp;2&#151;Basis of Presentation  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The accompanying unaudited financial information has been prepared by The Bank of New York Trust Company, N.A. ("Trustee"), in accordance with the instructions to
Form&nbsp;10-Q. The preparation of the financial statements requires estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting periods. Actual results could differ from those estimates. 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 Annual Report on Form&nbsp;10-K for the year ended December&nbsp;31, 2006. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
accordance with the instruments conveying the Royalty, the Working Interest Owners will calculate and pay the Trust each month an amount equal to 90% of the net proceeds for the
preceeding month. The 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 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. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
financial statements of the Trust are prepared on the following basis: </FONT></P>

<UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;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; </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;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; </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;Trust
general and administrative expenses, net of reimbursements, are recorded in the month they accrue; </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;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 </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;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. </FONT></P>

</UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
basis for reporting distributable 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 because 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. </FONT></P>


<P><FONT SIZE=2><B>Note&nbsp;3&#151;Legal Proceedings&#151;  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There are no pending legal proceedings to which the Trust is a named party. PNR has advised the Trustee that the previously reached 2006 settlement in the lawsuit </FONT> <FONT
SIZE=2><I>John Steven Alford and Robert Larrabee, individually and on behalf of a Plaintiff Class&nbsp;v. Pioneer Natural Resources USA,&nbsp;Inc.,</I></FONT><FONT SIZE=2> filed in
the 26th Judicial District Court, Stevens County, Kansas, was approved in the first quarter of 2007 by the Judge and the case was finalized in April&nbsp;2007. The plaintiffs in the above noted
lawsuit were royalty owners in oil and gas properties located in the Hugoton field, which are owned by Pioneer USA, a subsidiary of Pioneer Natural Resources Company ("Pioneer"). The plaintiffs sued a
predecessor company to Pioneer USA asserting various claims relating to alleged improper deductions in the calculation of royalties. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the agreement, Pioneer USA agreed to make cash payments to settle the plaintiffs' claims with respect to production occurring on and before December&nbsp;31, 2005.
Pioneer USA also agreed
to adjust the manner in which royalty payments to the class members will be calculated for production occurring on and after January&nbsp;1, 2006. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pioneer's
portion of the cash payment is approximately $32,700,000. Pioneer agreed to pay the cash portion in two installments. Pioneer advised the Trustee that the portion of the cash
payments net to the Trust's interest was approximately $1,000,000 paid on September&nbsp;30, 2006 and an expected payment of approximately $900,000 payable on September&nbsp;30, 2007. The
approximate $1,000,000 attributable to the Trust paid on September&nbsp;30, 2006, was deducted from royalty income in the fourth quarter of 2006. In October&nbsp;2007, Pioneer informed the Trustee
that during the course of Pioneer USA's analysis of the payments under the terms of the settlement agreement, Pioneer USA has now determined that the Trust should not bear any portion of the second
installment payment and that Pioneer USA should reimburse the Trust for the portion of the first installment payment previously charged to the Trust and paid in September&nbsp;2006. As a result,
Pioneer USA included a reimbursement of $1,096,630, including interest in the amount of $110,492, to the distribution made to the Trust in October&nbsp;2007 to be included in the Trust's fourth
quarter receipts, and no portion of the second installment payment will be charged to the Trust. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In a technical advice memorandum dated February&nbsp;26, 1982, the IRS advised the Dallas District Director that the Trust is classifiable as a grantor trust

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
following review of the Trust's financial condition and results of operations should be read in conjunction with the financial statements and notes thereto. The discussion of net
production attributable to the Hugoton and San Juan properties represents production volumes that are to a large
extent hypothetical as the Trust does not own and is not entitled to any specific production volumes. See Note&nbsp;7 to the financial statements in the Trust's Annual Report on
Form&nbsp;10-K for the year ended December&nbsp;31, 2006. Any discussion of "actual" production volumes represents the hydrocarbons that were produced from the properties in which the
Trust has an overriding royalty interest. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Trust is a passive entity whose purposes are limited to: (1)&nbsp;converting the Royalties to cash, either by retaining them and collecting the proceeds of production (until
production has ceased or the Royalties are otherwise terminated) or by selling or otherwise disposing of the Royalties; and (2)&nbsp;distributing such cash, net of amounts for payments of
liabilities to the Trust, to the unitholders. The Trust has no sources of liquidity or capital resources other than the revenues, if any, attributable to the Royalties and interest on cash held by the
Trustee as a reserve for liabilities or for distribution. </FONT></P>

Trust's Royalty income was $3,180,214 in the third quarter of 2007, an increase of approximately 57% as compared to $2,022,637 in the third quarter of 2006, primarily as a result of
increased royalty income from the San Juan Basin properties, higher natural gas prices, higher natural gas liquids production, as well as, a decrease in capital spending in the third quarter of 2007
as compared to the third quarter of 2006. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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

market clearing prices to multiple purchasers recently including Greely Gas and Oneok Gas Marketing,&nbsp;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 2007
compared to the third quarter of 2006. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
June&nbsp;1994, PNR entered into a Gas Transportation Agreement ("Gas Transportation Agreement") with Western Resources,&nbsp;Inc. ("WRI") for a primary term of five years
commencing June&nbsp;1, 1995. This contract has been renewed on a year-to-year basis since June&nbsp;1, 2001. PNR extended the contract through June&nbsp;1, 2008.
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&nbsp;1, 1996. This Gas Transportation Agreement has been assigned to Kansas Gas Service ("Oneok"). </FONT></P>

income attributable to the Hugoton Royalty Properties increased to $1,237,354 in the third quarter of 2007, as compared to $1,127,867 in the third quarter of 2006 primarily due
to an increase in overall prices received from the Hugoton Royalty Properties as well as an increase in gas production. The average price received in the third quarter of 2007 for natural gas and
natural gas liquids sold from the Hugoton Royalty Properties was $6.66 per Mcf and $46.86 per barrel, respectively, compared to $5.67 per Mcf and $41.17 per barrel during the same period in 2006. Net
production attributable to the Hugoton Royalty was 135,835 Mcf of natural gas and 6,639 barrels of natural gas liquids in the third quarter of 2007 compared to 123,530 Mcf of natural gas and 10,383
barrels of natural gas liquids in the third quarter of 2006. Actual production volumes attributable to the Hugoton properties increased to 188,313 Mcf of natural gas and decreased to 9,210 barrels of
natural gas liquids in the third quarter of 2007 as compared to 178,166 Mcf of natural gas and 10,389 barrels of natural gas liquids for the same period in 2006 as a result of new equipment to reduce
field fuel usage thus increasing overall production. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Trustee has been advised that beginning July&nbsp;1, 2007, the Hugoton and Panoma fields will be considered a single, common source of supply and will operate under a single
combined Basic Proration Order (BPO). After July&nbsp;1, 2007, the wells in each of these fields will be allowed to produce at their open flow potential and will no longer be subject to allowable

was $1,586,626 during the third quarter of 2007 as compared with $894,770 in the third quarter of 2006. The increase was primarily due to higher natural gas and natural gas liquids production and
decreased capital expenses and operating expenses in the third quarter of 2007. The average price received in the third quarter of 2007 for natural gas sold from the San Juan Basin Royalty Properties
was $5.59 per Mcf and $40.41 per barrel, respectively, compared to $5.24 per Mcf and $43.02 per barrel during the same period in 2006. Net production attributable to the San Juan Basin Royalty was
175,530 Mcf of natural gas and 15,019 barrels of natural gas liquids in the third quarter of 2007 as compared to 81,324 Mcf of natural gas and 10,893 barrels of natural gas liquids in the third

as compared to 236,843 Mcf of natural gas and 12,404 barrels of natural gas liquids for the same period in 2006. The increase in actual production volume for the three month period ended
September&nbsp;30, 2007 compared to the same period in 2006 was due to the better run times on conventional gathering. </FONT></P>

expenditures on these properties were $147,540 in the third quarter of 2007, a decrease of 51% as compared to $299,487 in the third quarter of 2006 due to a decrease in capital
facilities spending. Operating costs were $399,268 in the third quarter of 2007, a decrease of approximately 31% as compared to $580,448 in the third quarter of 2006. The decrease in operating
expenses for the three month period ended September&nbsp;30, 2007 compared to the same period in 2006 was due to a reduction in facilities expense and a reduction in well workover expenses. </FONT></P>

The Trustee is currently investigating the $142,566 difference in the original estimate of unpaid proceeds of $1,280,412 and the payments of $1,137,846. Since Royalty income for the Trust is
recorded on a cash basis, the third quarter 2006 earnings were not recognized as income until the quarters ended December&nbsp;31, 2006 and September&nbsp;30, 2006. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Royalty
income from the San Juan Basin&#151;Colorado Royalty Properties was $356,234 during the third quarter of 2007, compared to none received during the third quarter of 2006.
Royalty income received in the current quarter from Red Willow operated properties relating to undistributed earnings from prior periods totaled $206,836. The operators did not pay the Trust amounts
received during the third quarter of 2006, as discussed above. Net production attributable to the San Juan Basin Royalty Properties located in Colorado was 66,038 Mcf of natural gas during the third
quarter of 2007 with no volumes attributable to the Trust during the third quarter of 2006. The average price received in the third quarter of 2007 for natural gas sold from the San Juan Basin
Colorado Properties was $5.39. Actual production volumes attributable to the San Juan Basin Colorado Properties increased to 75,652 Mcf of natural gas in the third quarter of 2007 as compared to
45,818 Mcf of natural gas for the same period in 2006. Royalty income reported from BP is net of pre-main line production costs. These costs were charged to the Trust in error and as a
result royalty income for previous periods were reduced. Because royalty income recorded for a month is the amount computed and paid by BP, the additional royalties, if any, will not be recorded until
received, which is anticipated to be January&nbsp;2008. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating
costs on these properties were $51,519 in the third quarter of 2007, a decrease of approximately 63% as compared to $139,243 in the third quarter of 2006 attributed to a
decrease in maintenance work and lease operating expenses (labor, fuel, electricity, and chemicals). </FONT></P>

September&nbsp;30, 2007 for natural gas sold from the San Juan Basin Colorado Properties was $5.13. Actual production volumes attributable to the San Juan Basin Colorado Properties increased to
160,265 Mcf of natural gas for the nine months ended September&nbsp;30, 2007 as compared to 89,959 Mcf of natural gas for the same period in 2006. Royalty income reported from BP during the nine
months ended September&nbsp;30, 2007, is net of pre-main line production costs. These costs were charged to the Trust in error and as a result royalty income for previous periods were
reduced. Because royalty income recorded for a month is the amount computed and paid by BP, the additional royalties, if any, will not be recorded until received, which is anticipated to be
January&nbsp;2008. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating
costs on these properties were $85,184 for the nine months ended September&nbsp;30, 2007, a decrease of approximately 66% as compared to $248,553 in the same period in 2006
attributed to a decrease in maintenance work and lease operating expenses (labor, fuel, electricity, and chemicals). </FONT></P>

that information required to be disclosed by the Trust in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed,
summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that
information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act is accumulated and communicated by the working interest owners to The Bank of New York
Trust Company, N.A., as Trustee of the Trust, and its employees who participate in the preparation of the Trust's periodic reports as appropriate to allow timely decisions regarding required
disclosure. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As

<P><FONT SIZE=2>the
26th Judicial District Court, Stevens County, Kansas, was approved in the first quarter of 2007 by the Judge and the case was finalized in April&nbsp;2007. The plaintiffs in the above noted
lawsuit were royalty owners in oil and gas properties located in the Hugoton field, which are owned by Pioneer USA, a subsidiary of Pioneer Natural Resources Company ("Pioneer"). The plaintiffs sued a
predecessor company to Pioneer USA asserting various claims relating to alleged improper deductions in the calculation of royalties. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the terms of the agreement, Pioneer USA agreed to make cash payments to settle the plaintiffs' claims with respect to production occurring on and before December&nbsp;31, 2005.
Pioneer USA also agreed to adjust the manner in which royalty payments to the class members will be calculated for production occurring on and after January&nbsp;1, 2006. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
noted in prior disclosures, Pioneer's portion of the cash payment is approximately $32,700,000. Pioneer agreed to pay the cash portion in two installments. Pioneer has advised the
Trustee that the portion of the cash payments net to the Trust's interest was approximately $1,000,000 paid on September&nbsp;30, 2006 and an expected payment of approximately $900,000 payable on
September&nbsp;30, 2007. The approximate $1,000,000 attributable to the Trust paid on September&nbsp;30, 2006, was deducted from royalty income in the fourth quarter of 2006. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
October&nbsp;2007, Pioneer informed the Trustee that during the course of Pioneer USA's analysis of the payments under the terms of the settlement agreement, Pioneer USA has now
determined that the Trust should not bear any portion of the second installment payment and that Pioneer USA should reimburse the Trust for the portion of the first installment payment previously
charged to the Trust and paid in September&nbsp;2006. As a result, Pioneer USA included a reimbursement of $1,096,630, including interest in the amount of $110,492, to the distribution made to the
Trust in October&nbsp;2007, and no portion of the second installment payment will be charged to the Trust. </FONT></P>
