News release via Canada NewsWire, Calgary 403-269-7605

	    Attention Business Editors:
	    Penn West Energy Trust and Canetic Resources Trust announce Canetic
	    Unitholder and Court approval of combination

	    CALGARY, Jan. 9 /CNW/ - (TSX - PWT.UN; NYSE - PWE) Penn West Energy Trust
("Penn West") and (CNE.UN - TSX; CNE - NYSE) Canetic Resources Trust
("Canetic") are pleased to announce that the Plan of Arrangement (the
"Arrangement") related to the acquisition of Canetic by Penn West was approved
today at the Special Meeting of Canetic Unitholders with 92.1 percent of the
votes cast by Canetic Unitholders at the Special Meeting cast in favour of the
combination. The Alberta Court of Queen's Bench also granted the Final Order
required in connection with the Arrangement. Subject to satisfaction of
standard closing conditions, the combination of Penn West and Canetic is
expected to become effective on or about January 11, 2008, pursuant to which
Canetic Unitholders will receive 0.515 of a Penn West trust unit for each
Canetic trust unit exchanged. The exchange is intended to be completed on a
tax-deferred basis for Canadian and U.S. federal income tax purposes except
for those Canetic Unitholders who are subject to Canadian federal income tax
and who have validly elected to have the exchange completed on a taxable
basis. Canetic Unitholders of record at the close of business on January 10,
2008 will also receive a special one-time distribution of CDN $0.09 per
Canetic trust unit, as announced on January 7, 2008. The special distribution,
together with the distributions payable on the Penn West trust units following
completion of the Arrangement (assuming no changes to the current distribution
policies of Penn West), will effectively maintain the equivalent of Canetic's
pre-Arrangement monthly cash distributions to Canetic Unitholders for six
months following completion of the Arrangement, taking into account the trust
unit exchange ratio and the pre-Arrangement monthly distribution levels of
Penn West and Canetic.
	    The combination of Penn West and Canetic will create the largest oil and
gas energy trust in North America with an enterprise value of approximately
$14 billion, a significant portfolio of unconventional opportunities and a
dominant position in light oil in Canada. In addition, the new Penn West will
have a diversified portfolio of conventional oil and natural gas assets plus
significant resource-play potential in the Peace River oil sands of Northern
Alberta, CO2 enhanced oil recovery in the Pembina, Swan Hills, Midale and
Weyburn light oil pools and coalbed methane producing assets. Penn West will
be well positioned to create long-term value for its Unitholders (including
former Canetic Unitholders) through its high-quality, long-life asset base, a
strong balance sheet, and an extensive drilling inventory, together with
improved access to equity and debt markets resulting from Penn West's
increased size and strength. Penn West trust units trade on the Toronto Stock
Exchange under the symbol PWT.UN and on the New York Stock Exchange under the
symbol PWE. Canetic trust units and debentures are listed on the Toronto Stock
Exchange under the symbols CNE.UN, CNE.DB.A, CNE.DB.B, CNE.DB.C and CNE.DB.E
and Canetic trust units are listed on the New York Stock Exchange under the
symbol CNE.
