Trustee for the Permian Basin Royalty Trust, without audit, pursuant to the rules and regulations
of the Securities and Exchange Commission. Certain information and footnote disclosures normally
included in annual financial statements have been condensed or omitted pursuant to such rules and
regulations, although the Trustee believes that the disclosures are adequate to make the
information presented not misleading. It is suggested that these condensed financial statements
and notes thereto be read in conjunction with the financial statements and the notes thereto
included in the Trust&#146;s latest annual report on Form 10-K. In the opinion of the Trustee, all
adjustments, consisting only of normal recurring adjustments, necessary to present fairly the
assets, liabilities and trust corpus of the Permian Basin Royalty Trust at March&nbsp;31, 2010, and the
distributable income and changes in trust corpus for the three-month periods ended March&nbsp;31, 2010
and 2009 have been included. The distributable income for such interim periods is not necessarily
indicative of the distributable income for the full year.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have reviewed the accompanying condensed statement of assets, liabilities and trust corpus of
Permian Basin Royalty Trust (the &#147;Trust&#148;) as of March&nbsp;31, 2010, and the related condensed
statements of distributable income and changes in trust corpus for the three-month periods ended
March&nbsp;31, 2010 and 2009. These condensed financial statements are the responsibility of the
Trustee.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We conducted our reviews in accordance with the standards of the Public Company Accounting
Oversight Board (United States). A review of interim financial information consists principally of
applying analytical procedures and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in accordance with
the standards of the Public Company Accounting Oversight Board (United States), the objective of
which is the expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As described in Note 1 to the condensed financial statements, these condensed financial statements
have been prepared on a modified cash basis of accounting, which is a comprehensive basis of
accounting other than accounting principles generally accepted in the United States of America.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Based on our reviews, we are not aware of any material modifications that should be made to such
condensed interim financial statements for them to be in conformity with the basis of accounting
described in Note 1.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have previously audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), the statement of assets, liabilities, and trust corpus of Permian
Basin Royalty Trust as of December&nbsp;31, 2009, and the related statements of distributable income and
changes in trust corpus for the year then ended (not presented herein); and in our report dated
March&nbsp;1, 2010, we expressed an unqualified opinion on those financial statements. In our opinion,
the information set forth in the accompanying condensed statement of assets, liabilities, and trust
corpus as of December&nbsp;31, 2009, is fairly stated, in all material respects, in relation to the
statement of assets, liabilities and trust corpus from which it has been derived.

    <TD>The Permian Basin Royalty Trust (&#147;Trust&#148;) was established as of November&nbsp;1, 1980. The net
overriding royalties conveyed to the Trust include: (1)&nbsp;a 75% net overriding royalty carved
out of Southland Royalty Company&#146;s fee mineral interests in the Waddell Ranch in Crane
County, Texas (the &#147;Waddell Ranch properties&#148;); and (2)&nbsp;a 95% net overriding royalty carved
out of Southland Royalty Company&#146;s major producing royalty interests in Texas (the &#147;Texas
Royalty properties&#148;). The net overriding royalty for the Texas Royalty properties is
subject to the provisions of the lease agreements under which such royalties were created.

    <TD>All revenues from the Trust are from sources within Texas, which has no individual income
tax. However, Texas imposes a margin tax on generally all entity types providing limited
liability protection at a rate of 1% on gross revenues less certain deductions, as
specifically set forth in the Texas margin tax statute. Entities subject to tax generally
include trusts unless otherwise exempt. Trusts that receive at least 90% of their Federal
gross income from designated passive sources, including royalties from mineral properties
and other non-operated mineral interest income, and do not receive more than 10% of their
income from operating an active trade or business, generally are exempt from the Texas
margin tax as &#147;passive entities.&#148; The Trust should be exempt from Texas margin tax as a
&#147;passive entity.&#148; Since the Trust should be exempt from Texas margin tax at the Trust level
as a passive entity, each Unit holder that is considered a taxable entity under the Texas
margin tax will generally be required to include its portion of Trust revenues in its own
Texas margin tax computation. This revenue is sourced to Texas under provisions of the
Texas Administrative Code that provide such income is sourced according to the principal

uncertainties and the Trustee can give no assurance that they will prove correct. There are many

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The average received price of oil increased to an average price per barrel of $72.16 per Bbl in the
first quarter of 2010, compared to $41.10 per Bbl in the first quarter of 2009 due to worldwide
market variables. The Trustee has been advised by ConocoPhillips that for the period of August&nbsp;1,
1993, through March&nbsp;31, 2010, the oil from the Waddell Ranch properties was being sold under a
competitive bid to a third party. The average price of gas increased from $4.87 per Mcf in the
first quarter of 2009 to $7.31

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Since the oil and gas sales attributable to the Royalties are based on an allocation formula that
is dependent on such factors as price and cost (including capital expenditures), the production
amounts in the Royalties section of the above table do not provide a meaningful comparison. Oil
sales volumes increased and gas sales volumes increased from the Underlying Properties (as defined
in the Trust&#146;s Annual Report on Form 10-K for the year ended December&nbsp;31, 2009) for the applicable
period in 2010 compared to 2009.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Capital expenditures for drilling, remedial and maintenance activities on the Waddell Ranch
properties during the first quarter of 2010 totaled $1.1&nbsp;million as compared to $2.7&nbsp;million for
the first quarter of 2009. ConocoPhillips has informed the Trustee that the 2010 capital
expenditures budget has been revised to $43.0&nbsp;million for the Waddell Ranch properties. The total
amount of capital expenditures for 2009 was $43.1&nbsp;million. Through the first quarter of 2010,
capital expenditures of $1.1&nbsp;million have been expended.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Trustee has been advised that there were 6 workover wells completed, no new wells completed, no
new wells in progress and 6 workover wells in progress during the three months ended March&nbsp;31, 2010
as compared to 1 workover well completed, 0 new wells completed, 0 new wells in progress and 3
workover wells in progress for the three months ended March&nbsp;31, 2009 on the Waddell Ranch
properties.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Lease operating expense and property taxes totaled $4.4&nbsp;million for the first quarter of 2010,
compared to $3.84&nbsp;million in the first quarter of 2009 on the Waddell Ranch properties. This
increase is primarily attributable to increased maintenance work.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Trust&#146;s royalty income is computed as a percentage of the net profit from the operation of the
properties in which the Trust owns net overriding royalty interests. These percentages of net
profits are 75% and 95% in the case of the Waddell Ranch properties and the Texas Royalty
properties, respectively. Royalty income received by the Trust for the three months ended
March&nbsp;31, 2010 and 2009, respectively, were computed as shown in the table below:

not accrued in the period of production, general and administrative expenses recorded are based on
liabilities paid and cash reserves established rather than on accrual basis, and amortization of
the royalty interests is not charged against operating results. This comprehensive basis of
accounting other than GAAP corresponds to the accounting permitted for royalty trusts by the U.S.
Securities and Exchange Commission as specified by Staff Accounting Bulletin Topic 12:E, Financial
Statements of Royalty Trusts.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
June&nbsp;2009, the FASB issued guidance which changes how a company determines
when an entity that is insufficiently capitalized or is not controlled through voting (or similar
rights) should be consolidated. The determination of whether a company is required to consolidate
an entity is based on, among other things, an entity&#146;s purpose and design and a company&#146;s ability
to direct the activities of the entity that most significantly impact the entity&#146;s economic
performance. This guidance was effective for the Trust on January&nbsp;1, 2010 and the adoption did not
have an impact on the Trust&#146;s financial statements.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Revenues from the royalty interests are recognized in the period in which amounts are received by
the Trust. Royalty income received by the Trust in a given calendar year will generally reflect
the proceeds, on an entitlement basis, from natural gas produced and sold for the twelve-month
period ended October&nbsp;31st in that calendar year. Royalty income received by the Trust in the first
quarter of 2010 generally reflects the proceeds associated with actual oil and gas production for

attributable to the royalty interests. Estimates of future net revenues from proved reserves have
been prepared using year-end contractual gas prices and related costs. Numerous uncertainties are
inherent in estimating volumes and the value of proved reserves and in projecting future production
rates and the timing of development of non-producing reserves. Such reserve estimates are subject
to change as additional information becomes available. The reserves actually recovered and the
timing of production may be substantially different from the reserves estimates.

corresponding reductions to cash distributions to Unit holders. The Trustee is aware of no such

requires management to make estimates and assumptions that affect the reported amounts of certain
assets, liabilities, revenues and expenses as of and for the reporting period. Actual results may

<I>Modernization of Oil and Gas Reporting</I>. The new disclosure requirements include provisions that
permit the use of new technologies to determine proved reserves if those technologies have been
demonstrated empirically to lead to reliable conclusions about reserves volumes. The new
requirements also allow companies to disclose their probable and possible reserves to investors.
In addition, the new disclosure requirements require companies to: (a)&nbsp;report the independence and
qualifications of its reserves preparer or auditor; (b)&nbsp;file reports when a third party is relied
upon to prepare reserves estimates or conducts a reserves audit; and (c)&nbsp;report oil and gas
reserves using an average price based upon the prior 12-month period rather than year-end prices.
The new disclosure requirements are effective for financial statements for fiscal years ending on
or after December&nbsp;31, 2009. The effect of adopting the SEC rules did not have a significant effect
on our reported financial position or distributable income.

effectiveness of the design and operation of the Trust&#146;s disclosure controls and procedures

that the Trust&#146;s disclosure controls and procedures are effective in recording, processing,
summarizing and reporting, on a timely basis, information required to be disclosed by the Trust in
the reports that it files or submits under the Securities Exchange Act of 1934 and are effective in
ensuring that information required to be disclosed by the Trust in the reports that it files or
submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Trustee to
allow timely decisions regarding required disclosure. In its evaluation of disclosure controls and
procedures, the Trustee has relied, to the extent considered reasonable, on information provided by
