PERMIAN BASIN ROYALTY TRUST
 NOTES TO CONDENSED FINANCIAL STATEMENTS (UNAUDITED)
 1.
    
    BASIS OF ACCOUNTING
 The Permian Basin Royalty Trust (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 LP (BROG), a subsidiary of ConocoPhillips 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. Schlumberger Technology Corporation (STC) currently conducts all field,
technical and accounting operations on behalf of BROG with regard to the Waddell Ranch
properties. Riverhill Energy currently conducts the accounting operations for the
Texas Royalty properties. 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, 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s acquisition of Riverhill
Capital, the shareholders of Riverhill Capital acquired ownership
 7

##### 



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.In 2007 the Bank of America private wealth management group officially became known
as U.S. Trust, Bank of America Private Wealth Management. The legal entity that
serves as Trustee of the Trust did not change, and references in this Form 10-Q to
U.S. Trust, Bank of America Private Wealth Management shall describe the legal
entity Bank of America, N.A.
    
    Trust expenses recorded are based on liabilities paid and cash reserves established
out of cash received or borrowed funds for liabilities and contingencies.
    
    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 prepared in accordance with GAAP. 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.

New Accounting Pronouncements
  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. Royalty income generally is treated as portfolio income and
does not offset passive losses.
 Some Trust Units are held by middlemen, 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, collectively referred to herein as middlemen).
Therefore, the Trustee considers the Trust to be a non-mortgage widely held fixed investment
trust (WHFIT) for U.S. federal income tax purposes. U.S. Trust, Bank of America Private
Wealth Management, EIN: 56-0906609 901 Main Street, 17th Floor, Dallas, Texas 75202,
telephone number (214) 209-2400, 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. Tax information is also
posted by the Trustee at www.pbt-permianbasintrust.com. Notwithstanding the foregoing, the
 9

##### 



middlemen holding Trust Units on behalf of Unit holders, and not the Trustee of the Trust,
are solely responsible for complying with the information reporting requirements under the
U.S. Treasury Regulations with respect to such Trust Units, including the issuance of IRS
Forms 1099 and certain written tax statements. Unit holders whose Trust Units are held by
middlemen should consult with such middlemen regarding the information that will be reported
to them by the middlemen with respect to the Trust Units.Unit holders should consult their tax advisors regarding Trust tax compliance matters.3.
    
    STATE TAX CONSIDERATIONS
 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 passive entities. The Trust should be exempt from Texas margin tax as a
passive entity. 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
place of business of the Trust, which is Texas.
 Each Unit holder is urged to consult his own tax advisor regarding the requirements for
filing state tax returns.
 4.
    
    SUBSEQUENT EVENTS
 Subsequent to March 31, 2010, the Trust declared a distribution on April 20, 2010 of
$.120920 per unit payable on May 14, 2010, to Unit holders of record on April 30, 2010.
Subsequent events have been evaluated through the date of issuance of these
condensed financial statements.
 5.
    
    CONTINGENCIES
 Contingencies related to the Underlying Properties that are unfavorably resolved would
generally be reflected by the Trust as reductions to future royalty income payments to the
Trust with corresponding reductions to cash distributions to Unit holders. The Trustee is
aware of no such items as of March 31, 2010.

##### 



Basis of Accounting
  
    
    Royalty income and interest income are recorded in the period in which amounts are
received by the Trust rather than in the period of production and accrual, respectively.
 
    
    General and administrative expenses recorded are based on liabilities paid and cash
reserves established out of cash received.
 
    
    Amortization of the royalty interests is calculated on a unit-of-production basis and
charged directly to trust corpus when revenues are received.
 
    
    Distributions to Unit holders are recorded when declared by the Trustee (see Note 1 to
