<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 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 June&nbsp;30, 2005, and the distributable income and
changes in trust corpus for the three-month and six-month periods ended June&nbsp;30, 2005 and 2004 have
been included. The distributable income for such interim periods is not necessarily indicative of
the distributable income for the full year.

<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 as of June&nbsp;30, 2005, and the related condensed statements of
distributable income for the three-month and six-month periods ended June&nbsp;30, 2005 and 2004 and
changes in trust corpus for the three-month and six-month periods ended June&nbsp;30, 2005 and 2004.
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 standards of the Public Company Accounting Oversight
Board (United States). A review of interim financial information consists principally of applying
analytical procedures to financial data and of making inquiries of persons responsible for
financial and accounting matters. It is substantially less in scope than an audit conducted in
accordance with 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 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, 2004, 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;14, 2005, 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, 2004, 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. The financial statements of the Trust
are prepared on the following basis:</TD>

the Waddell Ranch properties. Riverhill Energy currently conducts the accounting

(&#147;Royalties&#148;) from the sale of production less accrued production costs, development and
drilling costs, applicable taxes, operating charges, and other costs and deductions

    <TD>The Trustee has been advised that in the first quarter of 1998, STC acquired all of the
shares of stock of Riverhill Capital. Prior to such acquisition by STC, CMC and Riverhill
Energy were wholly owned subsidiaries of Riverhill Capital. The Trustee has further been
advised that in connection with STC&#146;s acquisition of Riverhill Capital, the shareholders of
Riverhill Capital acquired ownership of all of the shares of stock of Riverhill Energy.
Thus, the ownership in the Texas Royalty properties referenced above remained in Riverhill
Energy, the stock ownership of which was acquired by the former shareholders of Riverhill

    <TD>Royalty income is computed separately for each of the conveyances under which the
Royalties were conveyed to the Trust. If monthly costs exceed revenues for any conveyance

carried forward with accrued interest to be recovered from future net proceeds of that
conveyance.</TD>

    <TD>The financial statements of the Trust differ from financial statements prepared in
accordance with accounting principles generally accepted in the United States of America
(&#147;GAAP&#148;) because revenues are not accrued in the month of production and certain cash
reserves may be established for contingencies which would not be accrued in financial
statements. Amortization of the Royalties calculated on a unit-of-production basis is
charged directly to trust corpus. 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.</TD>

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the quarter ended June&nbsp;30, 2005 royalty income received by the Trust amounted to $12,746,016
compared to royalty income of $9,045,654 during the second quarter of 2004. The increase in
royalty income is primarily attributable to significant increases in both oil and gas prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Interest income for the quarter ended June&nbsp;30, 2005, was $11,569 compared to $3,154 during the
second quarter of 2004. The increase in interest income is primarily attributable to higher
interest rates and more funds available for investment. General and administrative expenses during
the second quarter of 2005 amounted to $237,206 compared to $144,076 during the second quarter of
2004. The increase in general and administrative expenses can be primarily attributed to increased
expenses due to implementation and compliance with the Sarbanes-Oxley Act.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These
transactions resulted in distributable income for the quarter ended June&nbsp;30, 2005 was 12,520,379 or $.268627
per Unit of beneficial interest. Distributions of $.073306, $.092327 and $.102992 per Unit were
made to Unitholders of record as of April&nbsp;29, 2005, May&nbsp;31, 2005 and June&nbsp;30, 2005, respectively.
For the second quarter of 2004, distributable income was $8,904,732, or $.191053 per Unit of beneficial
interest.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Royalty income for the Trust for the second quarter of the calendar year is associated with actual
oil and gas production for the period of February, March and April of 2005 from the properties from
which the Trust&#146;s net overriding royalty interests (&#147;Royalties&#148;) were carved. Oil and gas sales

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The posted price of oil increased to an average price per barrel of $46.61 per Bbl in the second
quarter of 2005 compared to $33.89 per Bbl in the second quarter of 2004. The Trustee has been
advised by BROG that for the period of August&nbsp;1, 1993, through June&nbsp;30, 2005, 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 $4.98 per Mcf in the second quarter of 2004 to $6.43 per Mcf in the
second quarter of 2005 due to change in overall market variables.
</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
and gas sales volumes from the Underlying Properties (as defined in the Trust&#146;s Annual Report on
Form 10-K for the year ended December&nbsp;31, 2004) increased for the applicable period in 2005
compared to 2004.
</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 second quarter of 2005 totaled $4,461,869 as
compared to $2,679,989 for the
second quarter of 2004. BROG has informed the Trustee that the 2005 capital expenditures budget
has been revised to $14.3&nbsp;million for the Waddell Ranch properties. The total amount of capital
expenditures for 2004 was $13.2&nbsp;million. Through the second quarter of 2005, capital expenditures
of $5.3&nbsp;million have been expended.

workover wells completed and 13 workover wells in progress, during the three months ended June&nbsp;30,
2005 as compared to no wells completed, 4 wells in progress and 31 workover wells in progress for
the three months ended June&nbsp;30, 2004 on the Waddell Ranch properties. There was 1 facility project

$26,277,087 compared to royalty income of $18,252,328 for the six months ended June&nbsp;30, 2004. The
increase in royalty income is primarily due to an increase in oil and gas prices in the first six
months of 2005, compared to the first six months in 2004. Interest income for the six months ended
June&nbsp;30, 2005 was $23,043 compared to $6,652 for the six months ended June&nbsp;30, 2004. The increase
in interest income is attributable primarily to an increase in interest rates and more funds
available for investment. General and administrative expenses for the six months ended June&nbsp;30,
2005 were $535,899. During the six months ended June&nbsp;30, 2004, general and administrative expenses

compared to $31.84 per barrel for the same period in 2004. The increase in the average price of

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">demand. The increase in the average price of gas from $4.92 per Mcf for the six months ended June
30, 2004 to $6.39 per Mcf for the six months ended June&nbsp;30, 2005 is primarily the result of an
increase in the spot prices of natural gas.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Since the oil and gas sales volumes 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. The oil and gas sales volumes from the properties from which the Royalties are carved
have remained relatively constant for the applicable period of 2005 compared to 2004.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Capital expenditures for the Waddell Ranch properties for the six months ended June&nbsp;30, 2005
totaled $5.3&nbsp;million compared to $3.4&nbsp;million for the same period in 2004. BROG has previously
advised the Trust that the remaining 2005 capital expenditures budget for the Waddell Ranch
properties is $9&nbsp;million.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Trust has been advised that 4 oil wells were drilled and completed on the Waddell Ranch
properties during the six months ended June&nbsp;30, 2005, as compared to no oil wells drilled and
completed on the Waddell Ranch properties during the six months ended June&nbsp;30, 2004.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Lease operating expense and property taxes totaled $5.6&nbsp;million for the six months ended June&nbsp;30,
2005 compared to $4.7&nbsp;million for the same period in 2004. The increase in lease operating expense
is primarily attributable to higher electrical costs than in 2004.

<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 June&nbsp;30,
2005 and 2004, respectively, were computed as shown in the table below:

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

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

<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 Rules&nbsp;13a-15 and 15d-15 of the Exchange Act. Based upon that evaluation, the Trustee
concluded that the Trust&#146;s disclosure control and procedures are effective in timely alerting the
Trustee to material information relating to the Trust required to be included in the Trust&#146;s
periodic filings with the Securities and Exchange Commission. 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.
