Company: Permian Basin Royalty Trust (Trust)

Filing Type: Form 10-Q (Quarterly Report)

Reporting Period: Three and six months ended June 30, 2008

Business Overview: The Trust holds net overriding royalty interests in producing oil and gas properties in Texas, specifically the Waddell Ranch properties (75% interest) and Texas Royalty properties (95% interest). The Trust is a fixed investment trust taxed as a grantor trust, with Bank of America, N.A. serving as Trustee. Financial statements are prepared on a modified cash basis.

Key Financial Metrics

Note: The Trust has no debt. Liquidity is maintained through cash reserves and royalty receipts. All distributable income is typically distributed to unit holders.

Material Changes vs. Prior Period

• Revenue Surge: Royalty income increased significantly compared to the prior year periods. For the three months ended June 30, 2008, income rose to $27.3 million from $13.4 million in 2007. For the six-month period, income rose to $53.7 million from $27.3 million in 2007.
• Price Drivers: The increase is primarily attributable to substantial increases in oil and gas prices.
  • Oil: Average price per barrel increased to $97.94 (Q2 2008) and $92.75 (6-month 2008) compared to $55.49 and $53.72 in 2007, respectively.
  • Gas: Average price per Mcf increased to $10.17 (Q2 2008) and $9.82 (6-month 2008) compared to $6.78 and $6.95 in 2007, respectively.
• Production Volumes: While royalty income volumes increased, total oil and gas sales volumes from the underlying properties generally declined or remained flat compared to 2007 due to natural depletion, offset by higher prices.
• Capital Expenditures: Capital expenditures on the Waddell Ranch properties decreased significantly to $1.4 million (Q2 2008) from $5.7 million (Q2 2007) and $1.7 million (6-month 2008) from $8.5 million (6-month 2007).
• Expenses: General and administrative expenses increased slightly due to enhanced unit holder reporting requirements.

Outlook, Risks, and Management Commentary

• Subsequent Events: On July 21, 2008, the Trust declared a distribution of $0.234609 per unit, payable on August 14, 2008.
• Capital Budget: ConocoPhillips advised that the 2008 capital expenditures budget for the Waddell Ranch properties is $33.9 million. As of June 30, 2008, $1.7 million had been expended, leaving a remaining budget of $32.2 million.
• Drilling Activity: No new wells were completed in the first six months of 2008, compared to 13 in the same period in 2007. There were 2 wells in progress and 8 workover wells completed.
• Risks: The Trust's income is highly sensitive to oil and gas prices and production volumes. Forward-looking statements regarding reserves and production are subject to uncertainties including market variables, regulatory changes, and the recoverability of reserves.
• Tax Considerations: The Trust is a grantor trust; unit holders are responsible for reporting income. Texas margin tax effective Jan 1, 2008, may apply to unit holders who are business entities, though the Trust itself is likely exempt as a passive entity.

Investor Verification Checklist

• Price Sensitivity: Verify current oil and gas spot prices against the Trust's historical performance to model future distributions.
• Reserve Depletion: Review the latest reserve estimates to understand the long-term decline rate of the underlying properties, as production volumes are decreasing.
• Capital Expenditure Plans: Confirm the execution of the remaining $32.2 million capital budget for the Waddell Ranch properties to ensure maintenance of production levels.
• Accounting Basis: Note that financials are on a modified cash basis, not GAAP; royalty income reflects cash received, not necessarily production accrued in the period.
• Unit Count: Confirm the number of outstanding units (46,608,796 as of August 1, 2008) for per-unit calculations.
