</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The condensed financial statements included herein have been prepared by Bank of America, N.A. as
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, 2011, and the
distributable income and changes in trust corpus for the three-month periods ended March&nbsp;31, 2011
and 2010 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">The condensed financial statements as of March&nbsp;31, 2011 and 2010, included herein, have been
reviewed by Deloitte &#038; Touche LLP, an independent registered public accounting firm, as stated in
their report appearing herein.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Dallas, Texas
</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, 2011, and the related condensed
statements of distributable income and changes in trust corpus for the three-month periods ended
March&nbsp;31, 2011 and 2010. 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, 2010, 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, 2011, 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, 2010, is fairly stated, in all material respects, in relation to the
statement of assets, liabilities and trust corpus from which it has been derived.

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.
The financial statements of the Trust are prepared on the following basis:</TD>

    <TD>All revenues from the Trust are from sources within Texas, which has no individual income
tax. However, Texas imposes a franchise 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 franchise 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 franchise tax as &#147;passive entities.&#148; The Trust should be exempt from Texas franchise
tax as a &#147;passive entity.&#148; Since the Trust should be exempt from Texas franchise tax at the
Trust level as a passive entity, each Unit holder that is considered a taxable entity under
the Texas franchise tax will generally be required to include its portion of Trust revenues
in its own Texas franchise 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 place of business of the Trust, which is Texas.</TD>

first quarter of 2011, compared to $72.16 per Bbl in the first quarter of 2010 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, 2011, the oil from the Waddell Ranch properties was being sold under a
competitive bid to a third party. The average price of gas decreased from $7.31 per Mcf in the
first quarter of 2010 to $7.07 per Mcf in the first quarter of 2011 due to change in overall market
variables.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The financial statements of the Trust differ from financial statements prepared in accordance with
accounting principles generally accepted in the United States of America because royalty income is
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>

<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 2011 generally reflects the proceeds associated with actual oil and gas production for
the period of November&nbsp;2010 through January&nbsp;2011.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As of January&nbsp;1, 2011, independent petroleum engineers estimated the net proved reserves
attributable to the royalty interests. Estimates of future net revenues from proved reserves have
been prepared using average 12-month oil and gas prices, determined as an unweighted arithmetic
average of the first-day-of-the-month price for each month within the 12-month period preceding the
end of the most recent fiscal year, unless prices are defined by contractual arrangements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On May&nbsp;2, 2011, ConocoPhillips, as the parent company of BROG, the operator of the Waddell Ranch
properties, notified the Trustee that as a result of inaccuracies in ConocoPhillips&#146; accounting and
record keeping relating to the Trust&#146;s interest in proceeds from the gas plant production since
January&nbsp;2007, ConocoPhillips overpaid the Trust approximately $5.9&nbsp;million. ConocoPhillips
informed the Trustee that it intends to recoup the overpayment through adjustments to future
distributions over the next year, in a manner not yet determined, beginning with the July&nbsp;2011 distribution to the Trust.
Additionally, ConocoPhillips informed the Trustee that beginning with
the July&nbsp;2011
distribution, proceeds to the Trust relating to the gas plant production will be adjusted to
reflect ConocoPhillips&#146; calculation of the corrected interest.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The preparation of financial statements in conformity with the basis of accounting described above
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
differ from such estimates.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There have been no material changes in the Trust&#146;s market risk, as disclosed in the Trust&#146;s Annual

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As of the end of the period covered by this report, the Trustee carried out an evaluation of the
effectiveness of the design and operation of the Trust&#146;s disclosure controls and procedures
pursuant to Exchange Act Rules&nbsp;13a-15 and 15d-15. Based upon that evaluation, the Trustee concluded
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
Burlington Resources Oil &#038; Gas Company LP, the owner of the Waddell Ranch properties, and Riverhill
Energy Corporation, the owner of the Texas Royalty properties. There has not been any change in the
Trust&#146;s internal control over financial reporting during the period covered by this report that has
materially affected, or is reasonably likely to materially affect, the Trust&#146;s internal control over financial reporting.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">ConocoPhillips has informed the Trustee of a claim for overpayment to the Trust of approximately
$5.9&nbsp;million and that it plans to recoup the overpayment through adjustments to future
distributions over the next year. Although the Trustee is in the process of evaluating the claim
and cannot determine the likely outcome, such adjustments if made would reduce and could
potentially eliminate distributions over such time period.
