<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Mesa Royalty Trust (the "Trust") was created on November&nbsp;1, 1979. On that date, Mesa Petroleum Co., predecessor to Mesa Limited Partnership ("MLP") which was the predecessor
to MESA Inc., conveyed to the Trust an overriding royalty interest (the "Royalty") equal to 90% of the Net Proceeds (as defined in the Conveyance and described below) attributable to the specified
interests in properties conveyed by the assignor on that date (the "Subject Interests"). The Subject Interests consisted of interests 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 (the "Royalty Properties"). The Royalty is evidenced by counterparts of an Overriding Royalty
Conveyance dated as of November&nbsp;1, 1979 (the "Conveyance"). On April&nbsp;30, 1991, MLP sold its interests in the Royalty Properties located in the San Juan Basin field to ConocoPhillips.
ConocoPhillips sold the portion of its interests in the San Juan Basin Royalty Properties located in Colorado to MarkWest Energy Partners, Ltd. (effective January&nbsp;1, 1993) and Red Willow
Production Company (effective April&nbsp;1, 1992). On October&nbsp;26, 1994, MarkWest Energy Partners, Ltd. sold substantially all of its interest in the Colorado San Juan Basin Royalty Properties
to BP&nbsp;Amoco Company ("BP"), a subsidiary of BP p.l.c. Until August&nbsp;7, 1997, MESA Inc. operated the Hugoton Royalty Properties through Mesa Operating Co., a wholly owned subsidiary of
MESA Inc. On August&nbsp;7, 1997, MESA Inc. merged with and into Pioneer Natural Resources Company ("Pioneer"), formerly a wholly owned subsidiary of MESA Inc., and Parker&nbsp;&amp; 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. Substantially all of the San Juan Basin Royalty Properties located in New Mexico are operated by
ConocoPhillips. Effective January&nbsp;1, 2005, ConocoPhillips assigned its interest in an immaterial number of San Juan Basin Royalty Properties located in New Mexico to XTO Energy Inc. 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. </FONT></P>

October&nbsp;2, 2006, The Bank of New&nbsp;York Mellon Trust Company, N.A. (the "Trustee") succeeded JPMorgan Chase Bank, N.A. as Trustee of the Trust. JPMorgan Chase Bank,

Trustee will make cash distributions to the unitholders in January, April, July and October each year as discussed more fully in Note&nbsp;2; </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;the
Trust will terminate upon the first to occur of the following events: (i)&nbsp;at such time as the Trust's royalty income for two successive years is less than
$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

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Effective
January&nbsp;1, 2011, the Trustee is establishing a cash reserve for contingent liabilities and expenses in accordance with the Trust Indenture. The cash reserve will be
established through the
withholding of cash received during 2011 of approximately $83,333 per monthly distribution amount, or up to $250,000 per quarter, until the cash reserve is $1.0&nbsp;million. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;2&#151;Basis of Presentation  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The accompanying unaudited financial information has been prepared by the 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 period. 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, 2010. The Trust considers all highly liquid investments with a maturity of three months or less to be cash equivalents. Subsequent events were evaluated through
the issuance date of the financial statements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
accordance with the Conveyance, the Working Interest Owners are obligated to calculate and pay the Trust each month an amount equal to 90% of the Net Proceeds (as defined in the
Conveyance) attributable to the month. In 1985, the Trust Indenture was amended and the Trust conveyed to an affiliate of Mesa Petroleum Co. 88.5571% of the original Royalty (such transfer, the "1985
Assignment"). The effect of the 1985 Assignment was an overall reduction of approximately 88.56% in the size of the Trust. As a result, the Trust is now entitled to receive 11.44% of 90% of the Net
Proceeds attributable to each month. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;2&#151;Basis of Presentation (Continued) </B></FONT></P>

<P style="font-family:times;"><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>

<P style="font-family:times;"><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 style="font-family:times;"><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 style="font-family:times;"><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 are included in the calculation of the monthly distribution amount; </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;Amortization
of the Royalty is computed on a unit-of-production basis and is charged directly to trust corpus since such amount does not affect
distributable income; and </FONT></P>

<P style="font-family:times;"><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 later date as the
Trustee determines is required to comply with applicable law 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>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
basis for reporting distributable 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, these statements differ from financial statements prepared in accordance with accounting principles generally accepted in the United States of America because, 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, general and administrative expenses would be recorded in the month they accrue, and interest income for a month would be calculated only through the end of such month. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;3&#151;Legal Proceedings  </B></FONT></P>

<P style="font-family:times;"><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. The Trustee has been advised by PNR, ConocoPhillips and BP&nbsp;Amoco that it is subject to litigation in
the ordinary course of business for certain matters that include the Royalty Properties. While each of the working interest owners has advised the Trustee that it does not currently believe any of the
pending litigation will have a material adverse effect net to the Trust, in the event such matters were adjudicated or settled in a material amount and charges were made against Royalty income, such
charges could have a material impact on future Royalty income. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;4&#151;Income Tax Matters  </B></FONT></P>

<P style="font-family:times;"><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 and not as an association
taxable as a corporation. As a grantor trust, the Trust incurs no federal income tax liability and each unitholder is subject to tax on the unitholder's pro rata share of the income and expense of the
Trust as if the unitholder were the direct owner of a pro rata share of the Trust's assets. In addition, there is no state tax liability for the period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Trustee assumes that some Trust Units are held by a middleman, as such term is broadly defined in U.S. Treasury Regulations (and includes custodians, nominees, certain joint owners,
and brokers holding an interest for a custodian in street name). Therefore, the Trustee considers the Trust to be a non-mortgage widely held fixed investment trust ("WHFIT") for U.S.
federal income tax purposes. Bank of New&nbsp;York Mellon Trust Company, N.A., 919 Congress Avenue, Austin, Texas 78701, telephone number&nbsp;1-800-852-1422,
is the representative of the Trust that will provide tax information in accordance with applicable U.S. Treasury Regulations governing the information reporting requirements of the Trust as a WHFIT. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;5&#151;Excess Production Costs  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Excess production costs result when costs, charges, and expenses attributable to a Working Interest Property exceed the revenue received from the sale of oil, gas, and other hydrocarbons
produced from such property. The excess production costs must be recovered by the Working Interest Owners before any distribution of Royalty income from the properties will be made to the Trust. As of
March&nbsp;31, 2011 and December&nbsp;31, 2010, there were no excess production costs on the Trust Properties. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Note&nbsp;6&#151;Tax Assessment  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;PNR has advised the Trustee that it received a proposed assessment from the Kansas Department of Revenue on September&nbsp;10, 2009, for additional tax, penalty and interest of
approximately $4.1&nbsp;million resulting primarily from the settlement of the lawsuit </FONT><FONT SIZE=2><I>John Steven Alford and Robert Larrabee, individually and on behalf of a Plaintiff Class
v. Pioneer Natural Resources USA, Inc.</I></FONT><FONT SIZE=2> in early 2007. The portion of the tax assessment net to the Trust is approximately $181,000, which could adversely affect
Trust distributions. PNR has submitted a written response objecting to the proposed assessment. On March&nbsp;25, 2010, The Kansas Department of Revenue issued a final assessment, which included
additional interest and penalties, increasing the amount assessed to approximately $4.5&nbsp;million. The portion of the tax assessment net to the Trust is approximately $197,000, which could
adversely affect Trust distributions. PNR is challenging the March&nbsp;25, 2010 final assessment through the administrative process provided for under Kansas law. No assurance can be made that any
objections or disputed items raised by PNR will be successful. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;PNR
has also advised the Trustee as of September&nbsp;30, 2010, it has filed approximately $3.0&nbsp;million of severance tax refunds with the state of Kansas, the estimated share of
the refund due and already paid to the Trust is approximately $167,000. There can be no assurance that the state will agree to PNR's position which in turn could adversely affect Trust distributions
in the future. </FONT></P>

<P style="font-family:times;"><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;9 to the financial statements in the Trust's Annual Report on Form&nbsp;10-K for the year ended
December&nbsp;31, 2010. 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 style="font-family:times;"><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>

short-term and multi-month contracts. As discussed below, overall market prices received for natural gas from the Hugoton Royalty Properties were lower in the first quarter of 2011 compared to the
first quarter of 2010. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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&nbsp;1, 1995. This contract has renewed on a year-to-year basis being effective June&nbsp;1, 2001. The contract is renewed a year in advance, so PNR extended the contract to June&nbsp;1,
2012. Pursuant to the Gas Transportation Agreement, WRI agreed to compress and transport up to 160&nbsp;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 was assigned to Kansas Gas Service. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Royalty
income attributable to the Hugoton Royalty decreased to $608,701 in the first quarter of 2011, from $688,652 in the first quarter of 2010 primarily due to decreases in natural
gas prices from the Hugoton Royalty Properties, and increased capital expenditures, offset in part by higher natural gas liquids prices. The average price received in the first quarter of 2011 for
natural gas and natural gas liquids sold from the Hugoton Royalty Properties was $3.89 per Mcf and $47.58 per barrel, respectively, as compared to $4.38 per Mcf and $43.68 per barrel, respectively, in
the first quarter of 2010. Net production of natural gas attributable to the Hugoton Royalty decreased to 93,611&nbsp;Mcf in the first quarter of 2011 from 99,700&nbsp;Mcf in the first quarter of
2010. Net production of natural gas liquids attributable to the Hugoton Royalty decreased from 5,768&nbsp;barrels in the first quarter of 2010 to 5,140&nbsp;barrels in the first quarter of 2011.
Actual production volumes from the Hugoton properties increased to 146,105&nbsp;Mcf of natural gas and decreased to 7,866&nbsp;barrels of natural gas liquids in the first quarter of 2011 as
compared to 145,863&nbsp;Mcf of natural gas and 8,425&nbsp;barrels of natural gas liquids for the same period in 2010. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Hugoton capital expenditures were $31,721 in the first quarter of 2011, an increase of approximately 2,126% as compared to $1,425 in the first quarter of 2010. The increase in
capital expenditures was primarily due to increased drilling activity. Operating costs were $301,344 in the first quarter of 2011, a decrease of approximately 5% as compared to $316,279 in the first
quarter of 2010. The decrease in operating costs was primarily due to lower severance tax expense due to the lower gas price received. </FONT></P>

Properties located in the state of New Mexico was $826,935 during the first quarter of 2011 as compared with Royalty income of $1,053,631 in the first quarter of 2010. The decrease in Royalty income
was due primarily to reduction in volume production and decline in natural gas price for the first quarter of 2011 compared to the first quarter of 2010. Net production attributable to the San Juan

expenditures on these properties were $83,253 in the first quarter of 2011, a decrease of approximately 32% as compared to $122,755 in the first quarter of 2010, primarily due to

income from the San Juan Basin&#151;Colorado Royalty Properties was $63,568 during the first quarter of 2011, compared to $28,276 during the first quarter of 2010. The
increase in Royalty income was due to higher production volumes in the first quarter of 2011 offset in part by
lower gas prices. Net production attributable to the San Juan Basin Royalty Properties located in Colorado was 25,295&nbsp;Mcf of natural gas during the first quarter of 2011with 9,114&nbsp;Mcf of
natural gas attributable to the Trust during the first quarter of 2010. The average price received in the first quarter of 2011 for natural gas sold from the San Juan Basin Colorado Properties was
$2.51, as compared to average price of $3.06 for the first quarter of 2010. Actual production volumes attributable to the San Juan Basin Colorado Properties increased to 47,924&nbsp;Mcf of natural
gas in the first quarter of 2011 as compared to 41,469&nbsp;Mcf of natural gas for the same period in 2010. 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 the Royalty income for previous periods was 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 by the Trust. </FONT></P>

and 2008, and with respect to the quarterly reports during 2008 and for the first two quarters of 2009, the Trust did not file its reports in a timely manner due to the Trustee's need to
reconcile and verify ownership, calculations of the Trust's interest in proceeds and other information provided by working interest owners. This information was required by the reserve engineer to
prepare the reserve report for the Trustee to present the required reserve information in the SEC reports, and for the Trustee to complete the Trust's financial statements, and a review of the basis
for this information was needed prior to filing these reports. The source of this information is not within the control of the Trustee, and thus the initial information provided to the Trustee and the
timely receipt of accurate information for the preparation of these reports was not within scope of the Trustee's disclosure controls and procedures. The Trustee's review of certain information and
calculations by the working interest owners, along with an outside joint venture auditor, remains ongoing. See "Management's Discussion and Analysis of Financial Condition and Results of
Operations&#151;Liquidity and Capital Resources" under Item&nbsp;7 on Form&nbsp;10-K for the year ended December&nbsp;31, 2010 for information concerning controls and
