Penn West and Canetic to merge and create Canada's flagship energy trust


    The combination will form the largest conventional oil & gas trust in
    North America and create a world-class Canadian platform to compete
    against global energy companies and deliver superior unitholder returns.
    The Combined Trust will have a diverse and high quality asset base, a
    large portfolio of development opportunities, an experienced and strong
    organization, and a healthy balance sheet with significant financial
    capacity.

    CALGARY, Oct. 31 /CNW/ - Penn West Energy Trust ("Penn West") (TSX -
PWT.UN; NYSE - PWE) and Canetic Resources Trust ("Canetic") (TSX - CNE.UN;
NYSE - CNE) are pleased to announce that they have entered into a combination
agreement (the "Combination Agreement") that provides for the strategic
combination of Penn West and Canetic to form Canada's flagship energy trust
(the "Combined Trust"). The Combined Trust will be the largest conventional
oil and gas trust in North America with an enterprise value of over C$15
billion and current production of over 200,000 barrels of oil equivalent
("boe") per day. The combined asset portfolio will include interests in a
significant number of Western Canada's highest quality conventional oil and
natural gas pools and will also include a number of non-conventional growth
opportunities including oil sands, coalbed methane, shale gas and enhanced oil
recovery. At closing, this strategic merger of assets and people will operate
under the Penn West name and will be led by a combined management team and
Board of Directors.
    Under the terms of the Combination Agreement, Canetic unitholders will
receive 0.515 of a Penn West unit for each Canetic unit on a tax-deferred
basis for Canadian and U.S. tax purposes. Immediately prior to the closing of
the combination, a one-time special distribution of $0.09 per unit will be
paid to Canetic unitholders. The special distribution will keep Canetic
unitholders whole, in cash distributions, for a period of six months. Canetic
unitholders will receive an aggregate value of C$15.84 per Canetic unit based
on the closing price of Penn West units on the Toronto Stock Exchange ("TSX")
as at October 30, 2007 which represents a premium of 7.1 percent to the
closing price of Canetic units on the TSX as at October 30, 2007. On
completion of the combination, Penn West unitholders will own approximately 67
percent and Canetic unitholders will own approximately 33 percent of the
Combined Trust. Penn West units will continue to be listed on both the TSX and
the New York Stock Exchange ("NYSE").
    The combination is subject to stock exchange, court and regulatory
approval, and the approval of at least 66 2/3 percent of Canetic unitholders.
It is expected that the Canetic unitholder meeting to vote on the combination
and closing will occur in mid January 2008. An Information Circular is
expected to be mailed to unitholders of Canetic in December 2007.Highlights of the Combined Trust

    -   Creates Canada's flagship energy trust and the dominant
        independent light oil producer in Western Canada with production of
        approximately 200,000 to 210,000 boe per day in 2008 and conventional
        proven plus probable reserves in excess of 800 million boe
    -   A large inventory of unconventional opportunities including a
        multi-billion barrel (discovered heavy oil resources in place) Peace
        River Oil Sands Project, coalbed methane, shale gas and enhanced
        recovery from Canada's largest legacy light oil pools
    -   The increased size will assist in the future development of both its
        conventional and unconventional growth opportunities
    -   Pro forma asset base rivals senior North American exploration and
        production companies providing added flexibility in positioning the
        Combined Trust for 2011 and beyond
    -   The combined assets exhibit a compelling overlap and similarities in
        operating philosophies, which improve operating efficiencies, field
        optimization and cost reductions availed by economies of scale. The
        Combined Trust will operate approximately 80 percent of its
        production
    -   The larger size of the Combined Trust is expected to enhance
        liquidity on the Toronto Stock Exchange and New York Stock Exchange,
        increase its weighting in major indices including the S&P/TSX 60
        Index and should receive increased attention from both equity and
        income investors
    -   Increased liquidity and enhanced financial flexibility will allow
        expansion both domestically and internationally
    -   Estimated cash flow for 2008 of $2.0 to $2.2 billion and a capital
        program of $900 million to $1 billion directed to further enhance the
        combined asset portfolio
    -   Combined tax pools of over $5.5 billion at the end of 2007, plus the
        ability to increase the tax base using the trust model over the next
        three years, results in an efficient tax position well beyond 2011
    -   Safe harbour capacity for the issuance of new units under the Undue
        Expansion rules set out for income trusts by the Canadian Government
        will expand to approximately $8.7 billion on an equity basis in 2008,
        and approximately $15 billion on an equity basis in total
    -   Management team and Board of Directors which combines the best and
        most experienced personnel from each organizationWilliam E. Andrew, President and Chief Executive Officer of Penn West,
said, "We are bringing together two great organizations with world-class
assets and people to create an aggressive Canadian player in the global
markets. The Combined Trust will be well positioned to compete in North
America and internationally."
    J. Paul Charron, President and Chief Executive Officer of Canetic,
commented, "As I have stated many times in the past, sitting still in today's
dynamic market is not an option. This strategic combination brings together
two organizations with complementary strategies, asset bases and management
teams resulting in a strong shared future. I believe the Combined Trust is
more than the sum of its parts."

    Pro Forma Distributions

    It is anticipated that the Combined Trust's distribution will be set at 
C$0.34 per unit per month beginning with the first distribution payable
following completion of the combination. It is expected that this distribution
level will result in a 2008 payout ratio of approximately 67 percent to 72
percent. If the closing of the combination proceeds as planned, Canetic
unitholders will receive their first $0.34 monthly distribution effective with
the January 2008 Penn West distribution, payable on or about February 15,

the forward-looking statements and information because Penn West and Canetic
can give no assurance that they will prove to be correct.
    Since forward-looking statements and information address future events
and conditions, by their very nature they involve inherent risks and
uncertainties. Actual results could differ materially from those currently
anticipated due to a number of factors and risks. These include, but are not
limited to, the risks associated with the oil and gas industry in general such
as operational risks in development, exploration and production; delays or

expenses; health, safety and environmental risks; commodity price and exchange
rate fluctuations, marketing and transportation, loss of markets,
environmental risks, competition, incorrect assessment of the value of
acquisitions, failure to realize the anticipated benefits of acquisitions,
ability to access sufficient capital from internal and external sources,
failure to obtain required regulatory and other approvals, and changes in
legislation, including but not limited to tax laws and environmental
regulations. There are risks also inherent in the nature of the proposed
transaction, including failure to realize anticipated synergies or cost
savings; risks regarding the integration of the two entities; incorrect
assessments of the values of the other entity; and failure to obtain the

they believe are reasonable at this time, including assumptions as to the time
required to prepare meeting materials for mailing, the timing of receipt of
the necessary regulatory and court approvals and the time necessary to satisfy
the conditions to the closing of the transaction. These dates may change for a
number of reasons, including unforeseen delays in preparing meeting materials,
inability to secure necessary regulatory or court approvals in the time
assumed or the need for additional time to satisfy the conditions to the
completion of the transaction. Accordingly, readers should not place undue
reliance on the forward-looking statements and information contained in this
press release concerning these times.
    Readers are cautioned that the foregoing list of factors is not
exhaustive. Additional information on these and other factors that could
affect Penn West's, Canetic's or the Combined Trust's operations or financial

    Barrels of Oil Equivalent

    "Boe" means barrel of oil equivalent on the basis of 1 boe to 6,000 cubic
feet of natural gas. Boe's may be misleading, particularly if used in
isolation. A boe conversion ratio of 1 boe for 6,000 cubic feet of natural gas
is based on an energy equivalency conversion method primarily applicable at
the burner tip and does not represent a value equivalency at the wellhead.

    Non-GAAP Measures

    This press release uses the terms "payout ratio" and "EBITDA" (earnings
before interest, taxes, depreciation and amortization), which as presented do
not have any standardized meanings under Canadian generally accepted
accounting principles ("GAAP") and therefore such measures may not be
comparable to similar measures for other entities. "Payout ratio" is
calculated as cash distributions divided by cash flow from operating
activities. "EBITDA" is used by management to analyze operating performance
but should not be viewed as an alternative to cash flow from operating
activities, net income or other measures of financial performance calculated
in accordance with GAAP.

    Important Additional Information Will Be Filed With the SEC

    In connection with the proposed transaction, Penn West intends to, if
required, file relevant materials with the Securities and Exchange Commission
(the "SEC") on a Registration Statement on Form F-10 (the "Registration
Statement") to register the Penn West Units (the "Units") to be issued in
connection with the proposed transaction. Investors and unitholders are urged
to read the Registration Statement and any other relevant documents to be
filed with the SEC when available because they will contain important
information about Penn West and Canetic, the transaction and related matters.
Investors and unitholders will be able to obtain free copies of the
Registration Statement and other documents filed with the SEC by Penn West
through the website maintained by the SEC at www.sec.gov. In addition,
investors and unitholders will be able to obtain free copies of the
Registration Statement and such other documents when they become available
from Penn West by contacting Penn West Investor Relations at
