CALGARY, Jan. 9 /PRNewswire-FirstCall/ -- (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.
