Description of Material Change:</font></p>

<p style="margin:0pt 0pt 12.0pt 36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On
June&nbsp;30, 2006, Penn West and Petrofund announced that all Court and
regulatory approvals required to effect the merger of the trusts had been
received. As the unitholders of both trusts also approved the merger at their
respective unitholder meetings on June&nbsp;28, 2006, all conditions precedent
to the merger were satisfied and the merger was completed effective June&nbsp;30,
2006.</font></p>

<p style="margin:0pt 0pt 12.0pt 36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under
the arrangement, Petrofund unitholders will receive 0.6 of a Penn West unit for
each Petrofund unit exchanged. Petrofund unitholders will also receive a
separate special distribution of $1.10 that includes an adjustment of $0.10 per
unit required to align the distribution payment dates of the trusts.</font></p>

<p style="margin:0pt 0pt 12.0pt 36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
portions of the plan of arrangement related to the creation of a new junior oil
and natural gas exploration and production company (&#147;<b><font style="font-weight:bold;">ExploreCo</font></b>&#148;) were not completed. There was no distribution of
ExploreCo shares to unitholders and no conveyances of producing oil and natural
gas assets and undeveloped lands to ExploreCo. The assets and lands previously
earmarked for ExploreCo remain in the merged trust.</font></p>

<p style="margin:0pt 0pt 12.0pt 36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
merger of Penn West and Petrofund has created the largest energy trust in North
America with an enterprise value of approximately $11 billion including debt of
under one times annualized forecast cash flow. The new Penn West has a
diversified portfolio of conventional oil</font></p>
