                         PART I - FINANCIAL INFORMATION


ITEM 1.         FINANCIAL STATEMENTS

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'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 September 30,
2001, and the distributable income and changes in trust corpus for the
three-month and nine-month periods ended September 30, 2001 and 2000 have been
included. The distributable income for such interim periods is not necessarily
indicative of the distributable income for the full year.

Deloitte & Touche LLP, independent certified public accountants, has made a
limited review of the condensed financial statements as of September 30, 2001
and for the three-month and nine-month periods ended September 30, 2001 and 2000
included herein.

                         INDEPENDENT ACCOUNTANTS' REPORT


Bank of America, N.A.,
        as Trustee for the Permian Basin Royalty Trust

We have reviewed the accompanying condensed statement of assets, liabilities and
trust corpus of the Permian Basin Royalty Trust as of September 30, 2001 and the
related condensed statements of distributable income and changes in trust corpus
for the three-month and nine-month periods ended September 30, 2001 and 2000.
These financial statements are the responsibility of the Trustee.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with auditing standards generally accepted in the United States of
America, 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.

The accompanying condensed financial statements are prepared on a modified cash
basis as described in Note 1, which is a comprehensive basis of accounting other
than accounting principles generally accepted in the United States of America.

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.

We have previously audited, in accordance with auditing standards generally
accepted in the United States of America, the statement of assets, liabilities
and trust corpus of the Permian Basin Royalty Trust as of December 31, 2000, 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 20,
2001, 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 31, 2000 is fairly stated,
in all material respects, in relation to the statement of assets, liabilities
and trust corpus from which it has been derived.

PERMIAN BASIN ROYALTY TRUST

NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED)


1. BASIS OF ACCOUNTING

The Permian Basin Royalty Trust (the "Trust") was established as of November 1,
1980. The net overriding royalties conveyed to the Trust include: (1) a 75% net
overriding royalty carved out of Southland Royalty Company's fee mineral
interests in the Waddell ranch in Crane County, Texas (the "Waddell Ranch
properties"); and (2) a 95% net overriding royalty carved out of Southland
Royalty Company's major producing royalty interests in Texas (the "Texas Royalty
properties"). 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:

-       Royalty income recorded for a month is the amount computed and paid to
        Bank of America, N.A. ("Trustee") as Trustee for the Trust by the
        interest owners: Burlington Resources Oil & Gas Company ("BROG") for the
        Waddell Ranch properties and Riverhill Energy Corporation ("Riverhill
        Energy"), formerly a wholly owned subsidiary of Riverhill Capital
        Corporation ("Riverhill Capital") and formerly an affiliate of Coastal
        Management Corporation ("CMC"), for the Texas Royalty properties. CMC
        currently conducts all field, technical and accounting operations on
        behalf of BROG with regard to the Waddell Ranch properties. CMC also
        conducts the accounting operations for the Texas Royalty properties on
        behalf of Riverhill Energy. Royalty income consists of the amounts
        received by the owners of the interest burdened by the net overriding
        royalty interests ("Royalties") from the sale of production less accrued
        production costs, development and drilling costs, applicable taxes,
        operating charges, and other costs and deductions multiplied by 75% in
        the case of the Waddell Ranch properties and 95% in the case of the
        Texas Royalty properties.

        As was previously reported, in February 1997, BROG sold its interest in
        the Texas Royalty properties to Riverhill Energy.

        The Trustee has been advised that in the first quarter of 1998,
        Schlumberger Technology Corporation ("Schlumberger") acquired all of the
        shares of stock of Riverhill Capital. Prior to such acquisition by
        Schlumberger, CMC and Riverhill Energy were wholly owned subsidiaries of
        Riverhill Capital. The Trustee has further been advised that in
        connection with Schlumberger'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 Capital.

-       Trust expenses recorded are based on liabilities paid and cash reserves
        established out of cash received or borrowed funds for liabilities and
        contingencies.



                                       7
<PAGE>

-       Distributions to Unit holders are recorded when declared by the Trustee.

-       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 ("excess costs"), such excess cannot reduce
        royalty income from other conveyances, but is carried forward with
        accrued interest to be recovered from future net proceeds of that
        conveyance.

The financial statements of the Trust differ from financial statements prepared
in accordance with accounting principles generally accepted in the United States
of America ("GAAP") 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.

2. FEDERAL INCOME TAXES

For Federal income tax purposes, the Trust constitutes a fixed investment trust
which is taxed as a grantor trust. A grantor trust is not subject to tax at the
trust level. The Unit holders are considered to own the Trust's income and
principal as though no trust were in existence. The income of the Trust is
deemed to have been received or accrued by each Unit holder at the time such
income is received or accrued by the Trust and not when distributed by the
Trust.

The Royalties constitute "economic interests" in oil and gas properties for
Federal income tax purposes. Unit holders must report their share of the
revenues from the Royalties as ordinary income from oil and gas royalties and
are entitled to claim depletion with respect to such income.

The Trust has on file technical advice memoranda confirming the tax treatment
described above.

The classification of the Trust's income for purposes of the passive loss rules
may be important to a Unit holder. As a result of the Tax Reform Act of 1986,
royalty income will generally be treated as portfolio income and will not offset
passive losses.

ITEM 2.         TRUSTEE'S DISCUSSION AND ANALYSIS

FORWARD LOOKING INFORMATION

Certain information included in this report contains, and other materials filed
or to be filed by the Trust with the Securities and Exchange Commission (as well
as information included in oral statements or other written statements made or
to be made by the Trust) may contain or include, forward looking statements
within the meaning of Section 21E of the Securities Exchange Act of 1934, as
amended, and Section 27A of the Securities Act of 1933, as amended. Such forward
looking statements may be or may concern, among other things, capital
expenditures, drilling activity, development activities, production efforts and
volumes, hydrocarbon prices and the results thereof, and regulatory matters.
Although the Trustee believes that the expectations reflected in such
forward-looking statements are reasonable, such expectations are subject to
numerous risks and uncertainties and the Trustee can give no assurance that they
will prove correct. There are many factors, none of which is within the
Trustee's control, that may cause



                                       8
<PAGE>

such expectations not to be realized, including, among other things, factors
such as actual oil and gas prices and the recoverability of reserves, capital
expenditures, general economic conditions, actions and policies of
petroleum-producing nations and other changes in the domestic and international
energy markets. Such forward looking statements generally are accompanied by

THREE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2000

For the quarter ended September 30, 2001 royalty income received by the Trust
amounted to $8,433,236 compared to royalty income of $9,486,867 during the third
quarter of 2000. The decrease in royalty income is primarily attributable to
decreases in both oil and gas prices.

Interest income for the quarter ended September 30, 2001, was $17,543 compared
to $23,172 during the third quarter of 2000. The decrease in interest income is
primarily attributable to less funds available for investment. General and
administrative expenses during the third quarter of 2001 amounted to $74,320
compared to $46,979 during the third quarter of 2000. The increase in general
and administrative expenses can be primarily attributed to the timing of payment
of annual expenses.

These transactions resulted in distributable income for the quarter ended
September 30, 2001 of $8,376,459, or $.18 per Unit of beneficial interest.
Distributions of $.072291, $.59027 and $.048399 per Unit were made to Unit
holders of record as of July 31, August 31 and September 28, 2001, respectively.
For the third quarter of 2000, distributable income was $9,463,060, or $.20 per
Unit of beneficial interest.

Royalty income for the Trust for the third quarter of the calendar year is
associated with actual oil and gas production for the period of May, June and
July 2001 from the properties from which the Trust's net overriding royalty
interests ("Royalties") were carved. Oil and gas sales attributable to the
Royalties and the properties from which the Royalties were carved are as
follows:

</TABLE>

The posted price of oil decreased to an average price per barrel of $24.59 per
Bbl in the third quarter of 2001, compared to $28.44 per Bbl in the third
quarter of 2000. The Trustee has been advised by BROG that for the period August
1, 1993, through September 30, 2001, 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 $3.75 per Mcf in the third quarter of 2000 to $3.74 per Mcf
in the third quarter of 2001. This decrease is primarily attributable to the
softening market for natural gas nationwide.

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 from the Underlying Properties have decreased for the applicable period
in 2001 compared to 2000 being offset by increases in gas sales volumes.

Capital expenditures for drilling, remedial and maintenance activities on the
Waddell Ranch properties during the third quarter of 2001 totaled $394,000 as
compared to $1.1 million for the third quarter of 2000. BROG has informed the
Trustee that the 2001 capital expenditures budget has been revised to $4.6
million for the Waddell Ranch. The total amount of capital expenditures for 2000
was $4.6 million. Through the third quarter of 2001, capital expenditures of
$3.0 million have been expended.

The Trustee has been advised that there were 3 wells completed or in progress
during the three months ended September 30, 2001 as compared to no wells for the
three months ended September 30, 2000 on the Waddell Ranch properties.

Lease operating expense and property taxes totaled $2.6 million for the third
quarter of 2001, compared to $2.3 million in the third quarter of 2000 on the
Waddell Ranch properties. This increase is primarily attributable to higher
maintenance costs for the quarter.

NINE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 2000

For the nine months ended September 30, 2001, royalty income received by the
Trust amounted to $32,568,650 compared to royalty income of $24,897,284 for the
nine months ended September 30, 2000. The increase in royalty income is
primarily due to an increase in gas prices in the first nine months of 2001,
compared to the first nine months in 2000. Interest income for the nine months
ended September 30, 2001 was $68,002 compared to $56,476 for the nine months
ended September 30, 2000. The increase in interest income is attributable
primarily to an increase in funds available for investment. General and
administrative expenses for the nine months ended September 30, 2001 were
$371,336. During the nine months ended September 30, 2000, general and
administrative expenses were $329,646. The increase in general and
administrative expenses is primarily due to timing differences in the receipt
and payment of these expenses.

These transactions resulted in distributable income for the nine months ended
September 30, 2001 of $32,265,316, or $.692258, per Unit. For the nine months
ended September 30, 2000, distributable income was $24,624,114 or $.528315 per
Unit.

Royalty income for the Trust for the nine month period ended September 30, 2001
is associated with actual oil and gas production for the period through July
2001 from the properties from which the Royalties were carved. Oil and gas
production attributable to the Royalties and the properties from which the
Royalties were carved are as follows:

</TABLE>

The average price of oil decreased during the nine months ended September 30,
2001 to $25.59 per barrel compared to $27.06 per barrel for the same period in
2000. The decrease in the average price of oil is primarily due to lagging
demand in 2001, caused by a worldwide economic slowdown. The increase in the
average price of gas from $3.35 per Mcf for the nine months ended September 30,
2000 to $5.36 per Mcf for the nine months ended September 30, 2001 is primarily
the result of an increase in the spot prices of natural gas for the first nine
months of 2001.

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



                                       11
<PAGE>

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 2001 compared to 2000.

The Trust has been advised that 7 gross and 3 net productive oil wells were
drilled and completed on the Waddell Ranch properties during the nine months
ended September 30, 2001 or during the nine months ended September 30, 2000.
Capital expenditures for the Waddell Ranch properties for the nine months ended
September 30, 2001 totaled $2,999,000 compared to $4,500,000 for the same period
in 2000.

Lease operating expense and property taxes totaled $7.0 million in 2001 compared
to $7.4 million in 2000. The decrease in lease operating expense is primarily
attributable to more efficient field operations on the Waddell Ranch properties.

CALCULATION OF ROYALTY INCOME

The Trust'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 September 30, 2001 and
2000, respectively, were computed as shown in the table below:
