EXPLANATORY NOTE

Penn West Energy Trust (“Penn West”) is filing this Amendment No. 1 to its Annual Report on Form 40-F for the fiscal year ended December 31, 2008 (the “Form 40-F”) for the purpose of correcting several typographical errors included in Penn West’s Annual Information Form dated March 26, 2009 (the “Original AIF”), which was filed as Exhibit 99.1 to the Form 40-F.  Penn West is amending the Form 40-F in order to amend and restate Exhibit 99.1 thereto.

The typographical errors that are being corrected by this Amendment No. 1 appear in the table located on page 12 of Appendix A-3 of the Original AIF, under the column heading "Proved Plus Probable Gross Reserves as at December 31, 2008" and opposite the rows titled "Southern", "Central" and "Northern".  Although the numbers themselves are correct: (i) the proved plus probable gross reserves numbers for the "Southern" area incorrectly appear opposite the "Northern" row heading; (ii) the proved plus probable gross reserves numbers for the "Central" area incorrectly appear opposite the "Southern" row heading; and (iii) the proved plus probable gross reserves numbers for the "Northern" area incorrectly appear opposite the "Central" row heading.  The total proved plus probable gross reserves numbers as at December 31, 2008 in the table in the Original AIF are correct.

Other than as expressly set forth above or contained herein, this Amendment No. 1 does not, and does not purport to, update or restate the information in any Item of the Form 40-F or reflect any events that have occurred after the Form 40-F was initially filed.
