Penn West Confirms October Cash Distribution

Penn West confirmed that its October 2008 cash distribution will be C$0.34 per trust unit payable on November 14, 2008 to unitholders of record on October 31, 2008. The ex-distribution date is October 29, 2008.

The C$0.34 per unit is equivalent to approximately US $0.29 per unit (before deduction of any applicable Canadian withholding tax) using a current currency exchange of one Canadian dollar equals US $0.85.

Registered unitholders with U.S. addresses will receive their distributions directly from Penn West's transfer agent, and will be paid in U.S. currency using the exchange rate in effect on the record date. Non-registered U.S. unitholders will receive their distributions through their brokers.
