Penn West announces its results for the fourth quarter ended December 31, 2008
 

CALGARY, Feb. 18 /PRNewswire-FirstCall/ - PENN WEST ENERGY TRUST (TSX - PWT.UN; NYSE - PWE) is pleased to announce its results for the fourth quarter ended December 31, 2008

-------------------------------------------------------------------------

    Financial Results

    -   Funds flow(1) of $490 million in the fourth quarter of 2008 was 40
        percent higher than the $349 million realized in the fourth quarter
        of 2007. On a per-unit-basis(1) basic funds flow was $1.27 per unit
        in the fourth quarter of 2008 compared to $1.44 per unit in the
        fourth quarter of 2007.
    -   Net income of $404 million ($1.05 per unit-basic) in the fourth
        quarter of 2008 increased by 218 percent over net income of $127
        million ($0.53 per unit-basic) in the fourth quarter of 2007.
    -   The netback(1) of $27.31 per boe(2) in the fourth quarter of 2008
        was 16 percent lower than the fourth quarter of 2007.

    Operations

    -   Excluding corporate acquisitions, our capital program for 2008
        totalled $1,045 million. The program included $128 million of
        undeveloped land expenditures and $42 million of geological and CO(2)
        pilot costs aimed at increasing our future exploration and
        development potential. With this program, excluding the net property
        dispositions, we added a total of 58 million barrels of oil
        equivalent proved plus probable reserves, of which over 70 percent
        were oil and natural gas liquids.
    -   Including all capital expenditures and excluding corporate
        acquisitions, our proved plus probable finding and development cost
        was $18.94 per boe before the change in future development costs
        ("FDC") and $24.57 per boe including the change in FDC. Penn West's
        recycle ratio(1) was 1.9 times, excluding risk management impacts
        and 1.6 times, including risk management impacts in 2008 after the
        change in FDC.
    -   Production averaged 189,462 boe per day for 2008 compared to 127,098
        boe per day for 2007, an increase of 49 percent. During the fourth
        quarter of 2008, production averaged 184,908 boe per day compared to
        128,024 in the fourth quarter of 2007. Pro forma production for 2008,
        including Canetic and Vault production from January 1, was
        approximately 192,000 boe per day. Cold weather late in 2008
        negatively impacted production.
    -   Capital expenditures were $288 million in the fourth quarter of 2008
        and included $56 million of net asset dispositions. In the quarter, a
        total of 52 net wells were drilled with a success rate of 94 percent.

    Business Environment

    -   Concerns about economic growth and the credit markets continued
        through the fourth quarter of 2008 contributing to an average WTI
        crude oil price of US$58.76 per barrel compared to averages of
        US$118.13 per barrel in the third quarter of 2008 and US$90.63 in the
        fourth quarter of 2007. Due to strong prices through the first nine
        months of 2008, WTI crude oil averaged US$99.66 per barrel for 2008
        compared to US$72.34 per barrel in 2007.
    -   Natural gas prices at AECO (monthly index) in the fourth quarter of
        2008 averaged $6.43 per GJ, weakening from the $8.78 per GJ in the
        third quarter of 2008, but higher than the fourth quarter of
        2007 when prices averaged $5.69 per GJ. In the fourth quarter of
        2008, there was downward pressure on prices as a result of increased
        inventory levels in North America due to reductions in industrial
        demand. Overall, the 2008 AECO Monthly Index averaged $7.71 per GJ
        versus $6.26 per GJ in 2007.

    Financial Markets

    -   Penn West closely monitors the financial and credit markets and has
        implemented a number of initiatives aimed at further ensuring our
        financial strength through this time of uncertainty. Penn West
        recently reduced its planned 2009 capital program significantly
        compared to 2008, to between $600 million and $825 million and its
        distribution to $0.23 per unit per month. Spending in the first six
        months of 2009 will be less than one-half of our guidance as we
        anticipate a reduction in service costs throughout the year creating
        a more favourable drilling environment in the latter part of 2009.
    -   After completing two additional senior, unsecured note issues in
        2008, Penn West had approximately $1.4 billion of unutilized credit
        capacity under its $4.0 billion syndicated bank facility at year-end
        2008. Penn West's current bank facilities extend to January 2011.
    -   Our hedging position for 2009 consists of WTI collars on 30,000
        barrels per day of oil production at US$80.00 per barrel by US$110.21
        per barrel and 101,000 GJ per day of 2009 natural gas production
        under collars at $7.88 per GJ by $11.27 per GJ.
    -   Penn West expects to complete the sale of the previously announced
        group of properties for total proceeds of approximately $150 million
        prior to the end of February 2009. Additionally, in February 2009,
        Penn West entered into agreements for the sale of gross overriding
        royalties for total proceeds of approximately $40 million, all of
        which we expect to close prior to the end of March 2009. Proceeds
        from these transactions will be used to reduce bank debt.
    -   On February 5, 2009, Penn West closed the issuance of 17,731,000
        trust units on a bought-deal basis with a syndicate of underwriters
        at $14.10 per trust unit. The total gross proceeds raised of
        approximately $250 million ($238 million net) were used to further
        reduce bank debt.

    Distributions

    -   Penn West's Board of Directors recently resolved to reduce the
        Trust's distribution level to $0.23 per unit per month, effective
        with the January 2009 distribution paid in February subject to
        maintenance of current forecasts of commodity prices, production
        levels and planned capital expenditures.

    Regulatory

    -   In November 2008, the Government of Alberta announced further changes
        to the New Alberta Royalty Framework (the "NRF"). Effective November
        19, 2008, the Government provided transitional royalty rates on
        natural gas or conventional oil wells drilled at depths between 1,000
        and 3,500 metres until 2013. Companies have the one-time option of
        selecting the transitional royalty rates or the rates under the NRF.
        All Alberta wells are required to move to the NRF beginning on
        January 1, 2014. In the current commodity price environment, Penn
        West currently expects a 0.5 percent to 1.0 percent reduction to its
        corporate average royalty rate in 2009 as a result of these programs.

As confirmed by our independent third-party evaluators, Penn West's reserves continued to reflect a high concentration of proved developed reserves. Of total proved reserves, only 10 percent were undeveloped at December 31, 2008 compared to 12 percent at December 31, 2007. Of total proved plus probable reserves, only seven percent were undeveloped at December 31, 2008 compared to nine percent at December 31, 2007. In 2008, all of our reserves were evaluated or audited by GLJ Petroleum Consultants Ltd. ("GLJ") and Sproule Associates Limited ("SAL"), both independent engineering firms, of which approximately eight percent of total proved plus probable reserves were internally evaluated and externally audited.

Penn West's reserves also contain a high-netback product mix. At December 31, 2008 and 2007, on a proved plus probable basis, reserves other than heavy oil were 87 percent of total reserves on a barrel of oil equivalent basis.

GLJ Petroleum Consultants Ltd. and Sproule Associates Limited are Penn West's independent qualified reserve evaluators. The reserve estimates have been calculated in compliance with the National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). Under NI 51-101, proved reserve estimates are defined as having a high degree of certainty with a targeted 90 percent probability in aggregate that actual reserves recovered over time will equal or exceed proved reserve estimates. For proved plus probable reserves under NI 51-101, the targeted probability is an equal (50 percent) likelihood that the actual reserves to be recovered will be less than or greater than the proved plus probable reserves estimate.

Additional reserve disclosure tables, as required under NI 51-101, will be contained in Penn West's Annual Information Form that will be filed on SEDAR at www.sedar.com.

                          Letter to our Unitholders
    -------------------------------------------------------------------------

"We live in interesting times" is the most commonly heard phrase in most business discussions today. The year 2008 was marked by general market volatility resulting from extraordinary pressures on capital markets. Asset values fell from mid-year and the credit crisis impacted large financial institutions. Interbank borrowing rates rose and the overall access to credit tightened while commodity prices declined. Governments in most developed nations have responded with capital injections to banks and liquidity injections to certain markets. These are the financial waters through which we are navigating. The fundamentals of Penn West remain sound. Throughout 2008 and into 2009 we have proactively taken steps to ensure the Trust remains well-positioned.

Operations

Fourth quarter production averaged approximately 185,000 boe per day, a 44 percent increase over the fourth quarter of 2007, largely the result of the Canetic Resources Trust ("Canetic") acquisition completed in early January 2008. Funds flow for the quarter was $490 million representing an increase of 40 percent over this same period in 2007. We continued to reduce our finding and development costs ("F&D") in 2008. Based on proved plus probable reserve additions, excluding future development costs, we realized an F&D cost of $18.94 per boe in 2008. We note that our 2008 capital program, of approximately $1 billion, included $170 million for undeveloped land, geological and CO2 pilot expenditures aimed at continuing our efforts to set the table for long-term development.

2009 Capital Program

A year has passed since the acquisition of Canetic and although our performance suffered somewhat as we integrated Canetic into Penn West, we now view the integration of the staff, assets and support systems as complete. With the addition of Petrofund Energy Trust in 2006 and Canetic in 2008, we believe our combined entity's depth of opportunities, particularly in light oil, is extensive and provides our unitholders with an attractive inventory of value-adding development work for years to come.

Penn West has developed a base 2009 capital expenditure program of $600 million dollars with the option of increasing the program to $825 million dollars should industry service costs fall and commodity prices improve. This represents a 45 percent reduction from our 2008 capital program. A majority of the base program will be executed in the second half of the year as we expect industry services costs to fall through the year consistent with the reduction in activity levels driven by the decline in commodity prices. The base capital program is concentrated on low cost production adds from optimization activities, however, we have allocated funding to advance our enhanced oil recovery and resource play projects. As we look forward into 2009, we will be focusing our development efforts in three main areas.

Our southwest Saskatchewan, Lower Shaunavon play near Leitchville has been progressing well over the past three years. We plan on drilling approximately 30 horizontal multi-frac wells into this emerging play in 2009. With medium gravity oil, encouraging production rates, attractive per well reserve bookings, and continued cost reductions through efficiencies, this play remains very attractive even in a low-commodity price environment.

While the lead-time associated with full-scale development at our July Lake shale gas play is longer than that of the Lower Shaunavon play, the potential size of this play is substantial and we have significant operating advantages. Located east of the Horn River play and in proximity to our 100 percent owned Wildboy field, our operating advantages include an all-weather access road, existing gas processing and compression facilities and pipeline capacity directly in to the Alberta sales network. We will advance our efforts in this area early in 2009 adding to our existing wells, with completion work for these wells slated for later in the year.

Enhanced Oil Recovery (EOR) projects remain an important portion of Penn West's 2009 development plan as we aim to increase recovery rates from our substantial holdings of light oil fields. Recent advancements in completions technology using horizontal multi-frac wells look to be highly applicable in increasing recovery from these fields and should provide a significant intermediate step in the optimal recovery of our large oil pools, prior to moving into tertiary recovery techniques such as miscible floods using CO2 or other agents.

Balance Sheet Management

Penn West recently announced a reduction in our monthly distribution to unitholders from $0.34 per unit per month, a sustained level for 35 months, to $0.23 per unit per month. We have also been active in risk management, with calendar year 2009 WTI oil floors of US$80.00 on 30,000 barrels of oil per day and AECO natural gas floors of $7.88 per GJ on 101,000 GJ per day. These collars represent approximately 25 percent of our forecast 180,000 boe per day production in the first half of 2009 (prior to the effect of the 4,300 boe per day of property dispositions). We are focused on further improving our capital efficiency and on operating and general and administrative cost efficiencies. To this end we recently trimmed our total staff count by approximately 10 percent and froze salaries for management. We are also working with our suppliers to ensure our projects remain economic and are bolstering our cost control processes. We believe these actions are prudent in the current commodity price and financial market environment.

Financial

Although our $4 billion syndicated bank facility is not due for renewal until January 2011, we have been proactive in reducing both our absolute debt and our bank debt. We also completed two private note deals bringing our total long-term notes to approximately $1.3 billion. We are comfortable with our overall debt metrics, but we believe it is prudent in the current market to continue to actively mitigate against possible future market weakness. Our asset sales packages hit the market after the financial crisis set in but we did manage to raise approximately $190 million at reasonable values for additional bank debt retirement. In February of 2009, we raised $250 million ($238 million net) in a bought-deal equity offering and applied the proceeds to debt. We have adjusted our capital and distribution programs to ensure we remain in a strong position to capitalize on opportunities we believe these market events will present us.

We ended 2008 and began 2009 with economies around the world struggling. Through all of this, Penn West will continue to maintain a conservative strategy of financial prudence and proactive measures intended to ensure we emerge from this period of financial uncertainty well positioned to capitalize on opportunities and to continue the advancement of our many exciting prospects.

The management team of Penn West would like to thank our Board of Directors and staff for their counsel and efforts throughout 2008. Your contributions were significant in transforming Penn West into one of Canada's largest energy producers.

Non-GAAP Measures Advisory

The above information includes non-GAAP measures not defined under generally accepted accounting principles ("GAAP"), including funds flow, netback, payout ratio and recycle ratio. Non-GAAP measures do not have any standardized meaning prescribed by GAAP and are therefore unlikely to be comparable to similar measures presented by other issuers. Funds flow is cash flow from operating activities before changes in non-cash working capital and asset retirement expenditures. Funds flow is used to assess our ability to fund distributions and planned capital programs. Netback is a per-unit-of-production measure of operating margin used in capital allocation decisions. Operating margin is calculated as revenue less royalties, operating costs and transportation. Payout ratio is distributions paid divided by funds flow and we use it to assess the adequacy of funds flow to fund capital programs. Recycle ratio is calculated as the overall netback per boe for the period divided by finding and development costs per boe. We use recycle ratio to ensure our capital programs are adding reserves at an economic cost.

Oil and Gas Information Advisory

Barrels of oil equivalent (boe) are based on six mcf of natural gas equalling one barrel of oil (6:1). This could be misleading if used in isolation as it is based on an energy equivalency conversion method primarily applied at the burner tip and does not represent a value equivalency at the wellhead.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS
            For the three months and year ended December 31, 2008
    -------------------------------------------------------------------------

This management's discussion and analysis ("MD&A") of financial conditions and results of operations should be read in conjunction with the unaudited interim consolidated financial statements of Penn West Energy Trust ("Penn West", "the Trust", "We" or "Our") for the three months and year ended December 31, 2008 and the audited consolidated financial statements and MD&A for the year ended December 31, 2007. The date of this MD&A is February 18, 2009.

All dollar amounts contained in this MD&A are expressed in millions of Canadian dollars unless noted otherwise.

Please refer to our disclaimer on forward-looking statements at the end of this MD&A. The calculations of barrels of oil equivalent ("boe") are based on a conversion ratio of six thousand cubic feet of natural gas to one barrel of crude oil. This could be misleading if used in isolation as it is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated future development costs generally will not reflect total finding and development costs related to reserves additions for that year.

Measures including funds flow, funds flow per unit-basic, funds flow per unit-diluted, netback, recycle ratio and trailing funds flow included in this MD&A are not defined in generally accepted accounting principles ("GAAP") and do not have a standardized meaning prescribed by GAAP; accordingly, they may not be comparable to similar measures provided by other issuers. Management utilizes funds flow and netbacks to assess financial performance, to allocate its capital among alternative projects and to assess its capacity to fund distributions and future capital programs. We use recycle ratio to ensure our capital programs are adding reserves at an economic cost.

Reported results of operations, funds flow and net income include the acquisitions of Canetic Resources Trust ("Canetic") from the closing date of January 11, 2008, Vault Energy Trust ("Vault") from the closing date of January 10, 2008 and Endev Energy Inc. ("Endev") from the closing date of July 22, 2008.

Reconciliations of non-GAAP measures to their nearest measure prescribed by GAAP are provided below.

Financial Markets

Financial market volatility and credit market uncertainty began in the fall of 2007 and continues into 2009. Initially, the issues in the financial markets had little impact on Penn West as commodity prices continued to rise through the second quarter of 2008. Eventually, the combination of widespread deleveraging and high prices for all commodities led to a significant slowdown in essentially all of the world's economies. In July 2008, energy prices reached their highs and began to fall sharply; however the fall was partially offset by a decline in the Canadian dollar relative to the U.S. dollar. This market turmoil led to a loss of confidence, unprecedented response from governments to bolster the financial system, and significant price declines in many of the world's equity markets.

    During 2008, Penn West took several steps to strengthen its debt capital
structure through the following transactions:

    -   The placement of 3-year, $4.0 billion credit facilities maturing in
        2011. At December 31, 2008 we had approximately $1.4 billion of
        unutilized capacity under these facilities. We subsequently applied
        the proceeds of our equity issue and asset dispositions to further
        increase our credit capacity.
    -   The diversification of our debt portfolio through the further
        addition of senior, unsecured long-term private notes which now total
        $1.3 billion.
    -   The implementation of facilities with the TSX and NYSE to quickly
        raise capital as required or desired by way of "at-the-market"
        distributions of units.

    Penn West continued its risk management program throughout 2008 and into
2009 which aims to mitigate commodity price volatility and minimize credit and
foreign exchange exposure. Risk management activities included:

    -   Hedged approximately 31 percent of our 2009 crude oil production
        between WTI prices of US$80.00 per barrel and US$110.21 per barrel
        and approximately 20 percent of our 2009 natural gas production
        between AECO weighted average prices of $7.88 per GJ and $11.27 per
        GJ.
    -   Entered into foreign exchange contracts to swap US$720 million of
        U.S. dollar revenue for 2009 to Canadian dollars at an average rate
        of one U.S. dollar equals 1.25 Canadian dollars to fix the
        approximate floor value of our U.S. dollar denominated WTI collars in
        Canadian dollars. Subsequent to year-end, entered into an additional
        US$143 million of foreign exchange contracts to fix the remainder of
        the 2009 floor proceeds at an average rate of one U.S. dollar equals
        1.22 Canadian dollars.
    -   Entered into several additional interest rate swaps to fix the
        interest rate on floating rate debt at 2.80 percent on $500 million
        for two years and 2.31 percent on $800 million for three years to
        offset anticipated future increases in bank borrowing costs.
    -   Re-priced and extended the term of $650 million of existing interest
        rate swaps at a new average rate of 2.65 percent until January 2014.
    -   Monetized a portion of our crude oil financial contracts resulting in
        cash proceeds of approximately $123 million which were used to repay
        a portion of our credit facility.
    -   Closely monitored the risk of counterparty defaults.

In 2009, Penn West has taken additional actions in response to market conditions. We reduced our 2009 capital program and distribution level as a result of the current outlook for oil and natural gas prices, economic growth expectations and the state of the financial markets. Compared to 2008, our 2009 capital program was reduced significantly to between $600 million and $825 million. Spending in the first six months of 2009 is expected to be less than half of the annual planned range as we anticipate a reduction in service costs throughout the year creating a more favourable drilling environment in the latter part of 2009. The distribution level was reduced to $0.23 per unit effective with the January 2009 distribution paid in February 2009. Assuming 2009 average prices of WTI NYMEX ("WTI") US$45.00 per barrel, $5.50 per GJ natural gas at AECO and a Canadian to U.S. exchange rate of 1.25, we believe that we can fund our capital program and distributions with internally generated funds flow and the forecast proceeds of our distribution reinvestment program. We believe these actions are prudent in the current environment as the future condition of the credit and commodity markets can not be predicted with certainty at this time.

In February 2009, Penn West completed a bought-deal financing arrangement and issued 17,731,000 trust units for total proceeds of approximately $250 million ($238 million net). Penn West expects to complete the sale of the previously announced group of properties producing approximately 3,600 boe per day for total proceeds of approximately $150 million prior to the end of February 2009. Additionally, in February 2009, Penn West entered into an agreement for the sale of gross overriding royalties for total proceeds of approximately $40 million and total production of approximately 700 boe per day. This transaction is expected to close in March 2009. Proceeds from these transactions will be used to reduce bank debt.

Penn West is committed to modifying our business strategies as required to ensure our financial position remains strong. Increasing financial flexibility will increase our ability to act on future strategic opportunities which we believe will be available to us in 2009 and beyond.

Commodity Markets

Business Environment

The generally healthy global economic environment until the third quarter of 2008 resulted in increased demand for energy which outpaced the growth in supply. This was most evident in developing economies such as Asia and the Middle East. This strong demand resulted in steady upward pressure on commodity prices with oil peaking this past July at a historical high of over US$145.00 per barrel for the prompt month NYMEX WTI contract. These record commodity prices contributed in part to the economic slowdown which followed and caused most analysts to subsequently reduce their demand growth forecasts for energy products. North American demand for crude oil and refined products is believed to be in excess of 1.0 mmbbls per day lower than last year and some forecasters are expecting global oil demand to contract by another 1.0 mmbbls per day during 2009. In response to the resultant decline in energy prices, capital spending plans were significantly reduced by the oil industry, particularly plans related to mineable oil sands and upgrading projects. We believe this prompt response by industry will potentially bring oil supply and demand back into balance, and perhaps sooner than generally expected.

Crude Oil

WTI averaged US$99.66 per barrel in 2008 compared to US$72.34 per barrel in 2007. Crude prices started 2008 just below US$100.00 per barrel and then increased dramatically over the first six months. The credit crisis was not yet believed to affect the broader economy and the market was concerned that supply might not meet expected demand growth. After prices peaked in July, concerns regarding demand growth emerged along with the financial crisis causing prices to decline quickly, to below US$35.00 per barrel momentarily in December and subsequent to year-end. OPEC pledged two production cuts in the fourth quarter of 2008 in an effort to offset the decline in demand for oil. It is currently unknown whether OPEC's pledged production cuts will be sufficient to balance supply and demand, however, further OPEC cuts are promised by certain members of the cartel if supply and demand imbalances continue. Penn West believes that when economic conditions improve, the supply and demand for oil will re-balance in the mid-term due in part to re-emerging demand and secondly due to the supply issues. We believe that incremental future supply will be limited due to continuing depletion of existing fields and the cancellation or deferral of many large oil projects in response to current energy prices.

WTI crude oil prices averaged US$58.76 per barrel in the fourth quarter of 2008, down from US$118.13 per barrel in the third quarter of 2008 and US$90.63 per barrel for the fourth quarter of 2007. Penn West's fourth quarter 2008 crude oil price was also impacted by the high volatility in the Canadian to U.S. dollar exchange rate and the widening of differentials to reflect the oil quality and transportation costs associated with certain Canadian crude oils. Due to large inventories of gasoline in the U.S., Penn West's fourth quarter oil price was also impacted by abnormally high discounts on light sweet crude oil (compared to WTI), which makes up the largest portion of our crude oil production portfolio. Penn West's average crude oil and liquids price for the fourth quarter, before the impact of risk management, was $49.94 per barrel.

Natural Gas

Natural gas prices strengthened moderately in 2008 with the AECO Monthly Index averaging $7.71 per GJ versus $6.26 per GJ in 2007. In the first six months of 2008, the trend of natural gas prices was similar to crude oil prices primarily due to reduced imports of liquefied natural gas ("LNG") into the U.S., increased demand for natural gas in power generation and cold winter weather at the beginning of 2008. Due to the economic slowdown, the demand for natural gas has softened similar to oil with price declines since July. The industry responded to the downturn in natural gas prices by reducing natural gas drilling activity in North America, which, coupled with high initial decline rates for natural gas (particularly unconventional natural gas), is expected to reduce future supply.

Extremely high levels of drilling for unconventional gas over the past several years have resulted in high inventory levels across North America at a time when the demand for natural gas is expected to decline. This combination of events resulted in downward pressure on natural gas prices. The AECO Monthly Index in the fourth quarter of 2008 averaged $6.43 per GJ down from $8.78 per GJ in the third quarter, but higher than the fourth quarter of 2007 which averaged $5.69 per GJ. Penn West's corporate average gas price for the fourth quarter before the impact of risk management was $7.03 per mcf.

The New Alberta Royalty Framework

On October 25, 2007, the Government of Alberta (the "Government") released its new royalty framework (the "NRF") which became effective on January 1, 2009. The NRF maintains or continues certain programs that are important to Penn West, including the oil sands administrative status of the lands related to our Peace River Heavy Oil project, Enhanced Oil Recovery ("EOR") and Innovative Technology incentive programs important to the economics of our CO(2) and other EOR projects and the continuance of the Otherwise Flared Solution Gas Waiver Program supporting our environmental and asset optimization objectives.

Penn West, as the largest energy trust in North America by production, has a diversity of play types principally across the Western Canada Sedimentary Basin. Approximately 55 percent of our production is from Alberta Crown leases and our historical asset strategies have favoured mature light oil assets which generally remain economic under the NRF. In November 2008, the Government announced further royalty program changes. From November 19, 2008 until the end of 2013, the Government provided transitional royalty rates on natural gas or conventional oil wells drilled at depths between 1,000 and 3,500 metres. Producers have the one-time option of selecting the transitional royalty rates or the rates under the NRF and wells that adopt the transitional royalty rates are required to move to the NRF beginning on January 1, 2014. In the current commodity price environment, Penn West currently expects a 0.5 percent to 1.0 percent reduction to its corporate average royalty rate in 2009 as a result of these programs.

Enactment of the Tax on Income Trusts

On June 22, 2007, federal legislation was enacted implementing a new tax (the "SIFT Tax") on certain publicly traded income trusts and limited partnerships, referred to as "Specified Investment Flow-Through" ("SIFT") entities.

For SIFTs in existence on October 31, 2006 (including Penn West), the SIFT Tax will become effective in 2011. If certain rules related to "undue expansion" are not adhered to ("the normal growth guidelines"), the SIFT Tax will apply prior to 2011. Under the guidance provided by the Department of Finance, with the close of Vault and Canetic, we estimate that we can increase our equity by approximately $14 billion anytime between now and 2011 without prematurely triggering the SIFT Tax.

Under the SIFT Tax, distributions of certain types of income will not be deductible for income tax purposes by SIFTs in 2011 and thereafter and any resultant trust level taxable income will be taxed at a rate that will be approximately equal to corporate income tax rates. The SIFT Tax rate is currently 29.5 percent in 2011 and 28.0 percent thereafter.

On June 9, 2008, further changes to the SIFT Tax rules (the "Provincial SIFT Tax") were announced. These changes provide that the provincial component of the SIFT Tax is to be based on provincial corporate tax rates in provinces where the SIFT has a permanent establishment rather than using a 13 percent flat rate as originally legislated. On July 14, 2008 the Department of Finance released draft regulations which prescribe the detailed provincial allocation formula to be applied in respect of the Provincial SIFT Tax. As these regulations were not yet considered to be substantively enacted for accounting purposes at December 31, 2008, the 13 percent flat rate remains applicable for financial statement purposes. Under the proposed rules, Penn West currently has its only permanent establishment in the Province of Alberta. Accordingly, we expect that when these rules are enacted, the Provincial SIFT Tax applicable to Penn West will be reduced from 13 percent to 10 percent resulting in a combined SIFT Tax rate in 2011 of 26.5 percent and in 2012 of 25.0 percent.

The Legislative Proposals released by the Department of Finance on July 14, 2008 (the "Tax Proposals") also included draft legislation relating to the conversion of SIFT entities into corporations (the "SIFT Conversion Rules"). On November 28, 2008, the Minister of Finance introduced legislation into the House of Commons which included the SIFT Conversion Rules and on December 4, 2008 released Explanatory notes to accompany these changes. The effect of the SIFT Conversion Rules is to enable a conversion of a SIFT entity into a corporation without undue tax consequences for the SIFT entity or its investors and to facilitate such conversion with minimal filing requirements. The opportunity for a SIFT entity to apply these relieving provisions will only be available until the end of 2012. As of December 31, 2008, this legislation had not been enacted. The Explanatory notes also contained provisions to modify the Department of Finance's previously announced normal growth guidelines to eliminate the staging of the safe harbour limits for each of 2009 and 2010. This means the cumulative unused safe harbour limit, based on market capitalization on October 31, 2006, is available to be used in a single year anytime from December 4, 2008 to the end of 2010.

Penn West currently has a significant tax pool base, estimated at $6.0 billion on December 31, 2008. Based on current commodity prices, Penn West forecasts it could use these pools to shelter its taxable income for a period after the effective date of the SIFT Tax. Distributions sheltered by tax pools are not immediately taxable to the Trust or to unitholders. These distributions represent a return of capital which results in an adjustment to a unitholder's adjusted cost base of trust units. To the extent tax pools are insufficient to shelter distributions after 2010, the SIFT Tax would be payable and those distributions would be considered taxable dividends to unitholders taxed at a lower rate than current distributions of income as these distributions will generally be eligible for the dividend tax credit. As a result, the SIFT Tax should not adversely affect Canadian investors who hold Penn West units in a taxable account.

Our Board of Directors and management are continuously monitoring the impact of taxes on our business strategies. Penn West has a series of prospects which could be developed in the future in various stages. These opportunities include light oil, heavy oil, oil sands and natural gas conventional, enhanced recovery and resource plays. Current business plans are to evaluate the production, reserves potential and economics of developing this suite of prospects over the next two to four years under various price scenarios. The outcome of these evaluations will determine Penn West's most appropriate future business model however there are no current plans to convert out of the trust model until at least 2011.

    The SIFT Tax and the future business model determined to be appropriate
for Penn West will affect the tax position of both Penn West and its
unitholders including:

    -   If Penn West remains in the trust model after 2011, the distribution
        yield net of taxes to taxable Canadian investors will remain
        approximately the same; however, the after-tax distribution yield to
        tax-deferred Canadian investors (RRSPs, RRIFs, pension plans, etc.)
        and to foreign investors will be reduced;
    -   A portion of Penn West's funds flow after 2011 could be required for
        the payment of the SIFT Tax or corporate income tax (after its tax
        pools are consumed) as applicable, and would not be generally
        available for distribution or reinvestment;
    -   Penn West could convert to a corporate structure to facilitate
        investing a higher proportion of its funds flow in exploration and
        development projects and to capture the tax-free provisions available
        to convert out of the trust structure. Under the SIFT Conversion
        Rules there will be no adverse tax consequences due to a conversion
        to a corporation provided the conversion is completed prior to 2013.
        Such a conversion is dependent on the extent of Penn West's success
        in developing various plays over the next two to four years. The
        business model in this case would be a hybrid model where moderate
        growth is targeted along with providing investors an income stream in
        the form of dividends. While such a dividend stream would be at a
        lower payout ratio than the current trust distributions, the tax paid
        on the dividends would be lower for certain investors;
    -   Penn West may determine that it is more economic to remain in the
        trust structure for a period of time after 2010, strive to shelter
        its taxable income using tax pools and pay all or a portion of its
        distributions on a return of capital basis which attracts no current
        tax. Such distributions would likely be at a lower payout ratio than
        prior to the SIFT Tax. Distributions subject to the SIFT tax would be
        taxed as dividends and would be subject to a lower tax rate to
        certain investors than current distributions.

The Trust continues to review organizational structures and alternatives which might serve to reduce the impact of the SIFT Tax on Penn West and its unitholders. The release of the November 28, 2008 rules on SIFT conversions to corporations clarifies certain taxation aspects of this analysis. While there can be no assurance that the negative effect of the SIFT Tax can be minimized or eliminated, Penn West and its tax advisors continue to work diligently on these issues.

Canetic Acquisition

On January 11, 2008, the Trust closed the acquisition of Canetic. Under the Plan of Arrangement, Canetic unitholders received 0.515 of a Penn West trust unit for each Canetic unit on a tax-deferred basis for Canadian and U.S. tax purposes plus a one-time special distribution of $0.09 per unit under the terms of the Arrangement Agreement. The final allocation of the consideration paid to the fair value of the identifiable assets and liabilities was as follows:

Vault Acquisition

On January 10, 2008, the Trust closed the acquisition of Vault. The acquisition was accomplished through a Plan of Arrangement wherein Vault unitholders received 0.14 of a Penn West trust unit for each Vault unit and all Vault exchangeable shares were exchanged for Penn West trust units based on the exchange ratio for Vault units at the effective date of the Plan of Arrangement. The final allocation of the consideration paid to the fair value of the identifiable assets and liabilities was as follows:

    Endev Acquisition

    On July 22, 2008, the acquisition of Endev Energy Inc. ("Endev") was
successfully completed. Penn West issued approximately 3.6 million trust units
for total consideration of $115 million and assumed approximately $45 million
of debt and working capital. The acquisition was accomplished through a Plan
of Arrangement wherein Endev shareholders received 0.041 of a Penn West trust
unit for each Endev share.

    Penn West maintained a distribution of $0.34 per unit per month throughout
2008 and had continued that level since the rate was increased in February
2006. In 2009, the distribution level was decreased to $0.23 per unit per
month effective with the January 2009 distribution paid in February, as a
result of 2009 planned capital expenditures and 2009 forecasted commodity
prices.
    The total debt to trailing funds flow ratio remained at 1.5 in 2008 as a
result of strong funds flow due to high commodity prices for the first nine
months of the year.

    (1) Recycle ratio is calculated as the overall netback (excluding risk
        management impacts) per boe for the period divided by finding and
        development costs per boe.
    (2) Finding and development costs are calculated on a proved plus
        probable basis and include the change in future development capital.
        The average finding and development costs for the last three years
        were $30.15 per boe.
    (3) Net income before financing charges divided by average unitholders
        equity and average total debt.
    (4) Net income divided by average unitholders' equity.

The management and Board of Penn West evaluate the performance of the Trust based on three main categories; base operations, recycle ratio (netback divided by finding and development costs) and financial, business and strategic considerations.

Base operations includes our overall execution including production and operations, health and safety and environmental. Financial and business strategy includes the execution and quality of our asset and corporate acquisitions, portfolio management of our asset base, the quality of initiating and executing financial transactions, balance sheet stewardship, and that our strategic decisions and direction are accretive to our overall goal of creating unitholder value. We define unitholder value as the relative return on investment to our unitholders.

In 2008, Penn West's capital program, excluding corporate acquisitions, added a total of 58 million boe of proved plus probable reserves. Including all capital expenditures (except corporate acquisitions), our proved plus probable finding and development cost was $18.94 per boe before the change in future development costs ("FDC") and $24.57 per boe after the change in FDC. Excluding risk management impacts, Penn West's recycle ratio was 2.4 times before the change in FDC and 1.9 times after the change in FDC, which meets our targets. Various initiatives are under way to further improve our finding and development cost performance.

Penn West's annual production levels were generally in line with guidance provided in our third quarter 2008 MD&A, however, we were disappointed with our production performance compared to earlier guidance. As a result, the Trust recently re-organized certain parts of its business, including the executive level, and certain business processes have been modified to address these issues.

Subsequent to the integrations of the Canetic, Vault and Endev acquisitions in 2008, Penn West initiated a portfolio approach to analyzing its asset base which currently includes most play types and active areas of the Western Canada Sedimentary Basin as well as a multi-million-acre land base. Areas of future focus under various commodity price and industry service cost scenarios have been developed. At the same time, areas for divestiture were also identified to free up capital for the focus areas. We actively marketed assets for sale through the fall of 2008 and will realize proceeds from the sale of a portion of these assets of approximately $150 million. Additionally, in February 2009, Penn West entered into an agreement for the sale of gross overriding royalties for total proceeds of approximately $40 million which is expected to close in March 2009.

During 2008, various initiatives were successfully executed to protect Penn West from the credit crisis and to further diversify its debt capital structure as discussed earlier in this MD&A.

In 2008, we continued our strong focus on Health and Safety demonstrated through our injury rate decline for employees and contractors of 15 percent and eight percent, respectively, compared to 2007. In addition, we maintained a regulatory compliance record of 83 percent in Alberta which was eight percent higher than the industry average, we maintained our Certificate of Recognition based on our external health and safety management system audit and continued our Platinum level of Performance in the CAPP Stewardship program. In the year, we were recognized for our leadership in environmental performance and named as one of fifteen companies to the TSX Carbon Disclosure Leadership Index. Penn West continues to be in the forefront of Carbon Capture and Storage and currently has three commercial and two pilot CO(2)-EOR projects.

    Production in the fourth quarter of 2008 declined from the 190,177 boe per
day produced in the third quarter of 2008 primarily due to cold weather that
occurred late in the year.
    We strive to maintain an approximately balanced portfolio of liquids and
natural gas production provided it is economic to do so. We believe an
approximate balance helps to reduce exposure to price volatility that can
affect a single commodity. In the fourth quarter of 2008, crude oil and NGL
production averaged 105,644 barrels per day (57 percent of production) and
natural gas production averaged 476 mmcf per day (43 percent of production).
    We drilled 52 net wells with a success rate of 94 percent in the fourth
quarter of 2008 compared to 43 net wells at a success rate of 99 percent in
the same period of 2007.

    (1)  Light oil and NGL revenues for the year ended December 31, 2008
         includes $123 million relating to the monetization of a portion of
         the crude oil collars, $23 million in sulphur and other revenue and

    (2)  Gas revenue includes a $5 million adjustment relating to the final

         Wildboy fire.
    (3)  Gross revenues include realized gains and losses on commodity
         contracts.

The increase in revenue for 2008 over the comparative periods was the result of higher production volumes from the Canetic and Vault acquisitions and higher commodity prices compared to 2007. Light oil and liquid prices were 33 percent higher; natural gas prices were 23 percent higher and heavy oil prices were 65 percent higher than 2007.

Fourth quarter revenues declined compared to prior quarters in 2008 as a result of the significant weakening of energy prices. The decline was partially offset by gains on our commodity contracts and a weakening of the Canadian dollar relative to the U.S. dollar.

    -------------------------------------------------------------------------
    (1)  Excludes effects of risk management activities.

Royalties have increased year over year as a result of higher revenues from increased commodity prices and increased production volumes.

The average royalty rate in the fourth quarter of 2008 increased slightly in comparison to the fourth quarter of 2007 as a result of stable natural gas prices and significantly lower oil prices. Natural gas royalty rates are generally higher than oil, leading to a proportionately higher overall royalty rate.

Throughout 2008, upward pressure was placed on operating costs as a result of the high industry activity levels driven by the high commodity price environment experienced during the first nine months of the year. We experienced higher trucking, electricity and industry service costs in 2008. We expect operating costs to flatten in 2009 in response to both our initiatives and reduced industry activity resulting from lower energy prices.

A realized gain of $6 million (2007 - $11 million) on electricity contracts has been included in operating costs.

Financing

Penn West Petroleum Ltd. ("the Company") has unsecured, revolving, three-year syndicated bank facilities with an aggregate borrowing limit of $4.0 billion. The facilities consist of two revolving tranches; tranche one of the facility is $3.25 billion and extendible and tranche two is $750 million and non-extendible. The credit facility contains provisions for stamping fees on bankers' acceptances and LIBOR loans and standby fees on unutilized credit lines that vary depending on certain consolidated financial ratios.

On July 31, 2008, the Company issued (pnds stlg)57 million of senior unsecured notes (the "UK Notes") through a private placement in the United Kingdom maturing in 2018 and bearing interest at 7.78 percent. In conjunction with the issue of these notes, the Company entered into contracts to fix the principal and interest payments at approximately $114 million bearing interest in Canadian dollars at 6.95 percent. The Company used the proceeds to repay advances on its syndicated bank facility.

On May 29, 2008, the Company issued senior unsecured notes (the "2008 Notes") with an aggregate principal amount of US$480 million plus CAD$30 million through a private placement. The 2008 Notes have terms of eight to 12 years and bear interest at fixed rates between 6.12 percent and 6.40 percent with an average rate of approximately 6.25 percent. The Company used the proceeds of the issue to repay advances on its syndicated bank facility.

On May 31, 2007, the Company issued US$475 million of senior private notes (the "2007 Notes"). The interest rates on the 2007 Notes are fixed at 5.68 percent to 6.05 percent for terms of eight years to 15 years with an average interest rate of 5.80 percent. During September 2007, the Company entered into foreign exchange contracts to fix the repayment (in Canadian dollars) on US$250 million at an exchange rate of approximately one Canadian dollar equals one U.S. dollar.

In June 2008, the Company completed all requirements to enable the sale of trust units by way of "at-the-market distributions" on both the TSX and the NYSE. Penn West may issue and sell up to 20,000,000 trust units from time to time at its discretion during a period of up to 25 months. The trust units will be distributed at the current market price at the time of sale. The net proceeds from the sale of trust units under the facility, if any, will be used to repay debt or fund future growth opportunities. At December 31, 2008, no units had been issued under the facility.

On February 5, 2009, Penn West closed the issuance of 17,731,000 trust units on a bought-deal basis with a syndicate of underwriters at $14.10 per trust unit. The total gross proceeds raised of approximately $250 million ($238 million net) were used to repay a portion of our bank facility.

    At December 31, 2008, the Company had the following interest rate swaps
outstanding:

    -------------------------------------------------------------------------

The interest rates on the balance of the Company's bank debt are subject to fluctuations in the short-term money market rates as bank debt is generally held in short-term, floating interest rate debt instruments. As at December 31, 2008, 28 percent (2007 - 65 percent) of our long-term debt instruments were exposed to changes in short-term interest rates and 72 percent (2007 - 35 percent) of our long-term debt instruments contained fixed interest rates (including the effects of interest rate swaps).

In the fourth quarter of 2008, Penn West incurred $53 million of financing charges compared to $27 million in the same period of 2007 due to the increase in the average loan balance from the assumption of approximately $1.6 billion of bank debt and $360 million of convertible debentures on the Canetic and Vault acquisitions, and the higher interest rates on the 2008 Notes and the UK Notes. The senior notes contain higher fixed interest rates than the Company was subject to under its syndicated bank facilities using short-term money market instruments. Penn West believes the long-term nature and the fixed interest rates inherent in the senior notes are favorable for a portion of its debt capital structure.

Unit-Based Compensation

Unit-based compensation expense related to Penn West's Trust Unit Rights Incentive Plan is based on the fair value of trust unit rights issued, determined using the Binomial Lattice option-pricing model. The fair value of rights issued is amortized over the remaining vesting periods on a straight-line basis. The unit-based compensation expense was $12 million for the three months ended December 31, 2008, of which $3 million was charged to operating expense and $9 million was charged to general and administrative expense (2007 - $6 million, $2 million and $4 million, respectively). The charge increased in the fourth quarter of 2008 compared to the fourth quarter of 2007 due to the trust unit rights granted to employees retained from the Canetic and Vault acquisitions in January 2008.

    General and Administrative Expenses ("G&A")

    -------------------------------------------------------------------------

Increases in 2008 are primarily related to additional staffing levels and activities as a result of the Canetic and Vault acquisitions completed in January. Historically, Canetic had a higher administrative cost per boe in comparison to Penn West, which has contributed to the increase in 2008.

During the fourth quarter of 2008, to streamline administrative functions, Penn West implemented plans to restructure its internal operations. As a result of this reorganization, a charge of $6 million was included in G&A for the fourth quarter of 2008 related to the severance of certain administrative and operating staff.

    Depletion, Depreciation and Accretion ("DD&A")

    Penn West accounts for its corporate acquisitions using the purchase
method, where the purchase price is allocated to the fair value of net
identifiable assets acquired. The Canetic and Vault (2006 - Petrofund)
purchase price allocations to oil and natural gas assets, at fair value,
increased our consolidated depletion base per boe.

    Taxes

    Future income tax expense (reduction)        $   135   $    75   $  (106)
    -------------------------------------------------------------------------

The future income tax expense for the year ended December 31, 2008 includes a charge of approximately $198 million related to unrealized risk management gains. The future income tax expense for the year ended December 31, 2007 included a $326 million charge due to substantive enactment of the SIFT tax legislation during that period.

Under our current structure, the operating entities make interest and royalty payments to the Trust, which transfers taxable income to the Trust to eliminate income subject to corporate income taxes in the operating entities. The Trust in turn eliminates its taxable income by paying distributions to unitholders. Under the SIFT legislation, such amounts transferred to the Trust could be taxable to the Trust beginning in 2011 as distributions will no longer be deductible by the Trust for income tax purposes. At that time, Penn West could claim its tax pools to reduce income at the Trust level and pay all or a portion of its distributions on a return of capital basis. Such distributions would not be immediately taxable to investors: they would generally reduce the adjusted cost base of units held by investors however such distributions would likely be at a lower payout ratio.

The SIFT Tax legislation is not currently expected to directly affect our funds flow levels and distribution policies until 2011 at the earliest.

The estimate of future income taxes is based on the current tax status of the Trust. Future events that could materially affect future income taxes, such as acquisitions and dispositions and modifications to the distribution policy, are not reflected under Canadian GAAP until the events occur and the related legal requirements have been fulfilled. As a result, future changes to the tax legislation could lead to a material change in the recorded amount of future income taxes.

The increase in the 2008 tax pools reflects current year corporate acquisitions in addition to drilling and development activities. The tax pool figures are net of income deferred in operating partnerships.

Foreign Exchange

In the fourth quarter of 2008, the Trust recorded an unrealized foreign exchange loss of $139 million (2007 - $1 million gain) to translate the U.S. and UK notes to Canadian dollars at the exchange rates in effect on the balance sheet date. No realized gains or losses will be recorded on these contracts until settlement.

    (1)  Funds flow is a non-GAAP measure. See "Calculation of Funds Flow".

Funds flow realized in 2008 increased to record levels due to increased product prices and higher production volumes partially offset by higher operating and financing costs.

The significant increase in net income in 2008 compared to 2007 was due to stronger commodity prices and increased production, partially offset by higher depletion, operating and financing costs.

Net income in the fourth quarter of 2008 increased from the comparative 2007 period primarily due to realized and unrealized risk management gains.

    -------------------------------------------------------------------------

The goodwill impairment test consists of two parts. Under part 1, if the fair value of the reporting entity is less than its book value, part 2 of the test must be performed. As at December 31, 2008, due to the widespread decline in equity markets, Penn West proceeded to part 2 of the test where a reporting entity is required to calculate a purchase equation on its assets and liabilities at fair value on the balance sheet date. Under part 2, an equity control premium of 20 percent was used and the fair value of property, plant and equipment was estimated using forward strip commodity prices at year-end escalated at two percent per year subsequent to the end of available market data and a discount rate of 15 percent. Penn West determined there was no goodwill impairment at December 31, 2008.

A 1% change in the assumed control premium and a 1% change in the assumed discount rate applied to estimated cash flows change the fair value of Penn West by approximately $55 million and $350 million, respectively.

We drilled 52 net wells in the fourth quarter of 2008, resulting in 34 net oil wells, 11 net natural gas wells and 4 stratigraphic wells, with a success rate of 94 percent. During the quarter, our drilling activities were concentrated in our Light and Heavy oil areas. The expenditures on land acquisition and retention reflect activity to increase our acreage in areas conducive to our resource play strategies.

For the year ended December 31, 2008, $11 million (2007 - $5 million) was capitalized for future income taxes to reflect acquisitions with a tax basis differing from the purchase price and $25 million (2007 - $97 million) was capitalized for additions to asset retirement obligations to reflect the additional retirement obligations from both capital programs and net property acquisitions.

CO(2) pilot costs represent capital expenditures related to the Pembina CO(2) pilot project, including the cost of injectants, for which no incremental reserves have been booked.

Business Risks

The disclosures under this heading, in conjunction with Note 10 to the unaudited interim consolidated financial statements, are incorporated into and are an integral part of, the unaudited interim consolidated financial statements.

We are exposed to normal market risks inherent in the oil and natural gas business, including commodity price risk, credit risk, interest rate risk, foreign currency risk and environmental and climate change risk. From time to time, we attempt to mitigate our exposure to these risks by using financial instruments and by other means.

Commodity Price Risk

Commodity price fluctuations are among the Trust's most significant exposures. Crude oil prices are influenced by worldwide factors such as OPEC actions, supply and demand fundamentals, and political events. Oil prices, North American natural gas supply and demand fundamentals including weather, storage levels and LNG imports, influence natural gas prices. In accordance with policies approved by our Board of Directors, we may, from time to time, manage these risks through the use of swaps, collars or other financial instruments up to a maximum of 50 percent of forecast sales volumes, net of royalties, for the balance of any current year plus one additional year forward and up to a maximum of 25 percent for one additional year thereafter.

For a summary of outstanding oil and natural gas contracts, please refer to "Financial Instruments" later in this MD&A and to Note 10 to our unaudited interim consolidated financial statements.

Foreign Currency Rate Risk

Prices received for crude oil are referenced to or denominated directly in U.S. dollars, thus realized oil prices are impacted by U.S. to Canadian exchange rates. When we consider it appropriate, we may use financial instruments to fix or collar future exchange rates in addition to the use of U.S. dollar denominated borrowings and related interest expense.

In September 2007, we entered into foreign exchange contracts to fix the foreign exchange rate on the future repayment of US$250 million of U.S. dollar denominated private notes at an exchange rate of approximately one Canadian dollar equals one U.S. dollar. In July 2008, the Company entered into contracts to swap the principal amount of the UK Notes at a rate of $2.0075 per British pound or to a Canadian dollar equivalent amount of approximately $114 million, bearing interest in Canadian dollars at 6.95 percent. At December 31, 2008, we had U.S. dollar denominated debt with a face value of US$705 million outstanding on which the repayment of the principal amount in Canadian dollars is not fixed.

In the fourth quarter of 2008, Penn West entered foreign exchange contracts to swap US$720 million of U.S. dollar revenue for 2009 to Canadian dollars at an average rate of one U.S. dollar equals 1.25 Canadian dollars to fix the floor price of our U.S. dollar denominated oil collars at approximately $100 Canadian per barrel. Subsequent to year-end, Penn West entered into an additional US$143 million of foreign exchange contracts to fix the remainder of the 2009 floor proceeds at an average rate of one U.S. dollar equals 1.22 Canadian dollars.

Credit Risk

Credit risk is the risk of loss if purchasers or counterparties do not fulfill their contractual obligations. Our receivables are principally with customers in the oil and natural gas industry and are subject to normal industry credit risk. For oil and natural gas sales and financial derivatives, Penn West follows a counterparty risk procedure whereby each is reviewed on a regular basis and assigned a credit limit and is requested to provide security if deemed necessary. Penn West normally transacts with counterparties who are members of our banking syndicate or who have investment grade ratings. Due to the increasing uncertainty in current financial markets, Penn West monitors credit events related to all counterparties and reassesses credit exposures on a regular basis. As necessary, Penn West records provisions for credit related risks.

As at December 31, 2008, the maximum exposure to credit risk was $834 million (December 31, 2007 - $277 million) being the carrying value of the accounts receivable and risk management assets. Management continuously monitors credit risk and credit policies to ensure exposures to customers are limited.

On July 22, 2008, one of Penn West's minor oil marketing counterparties, SemGroup LP ("SemGroup") entered creditor protection. Penn West sold oil to subsidiary companies of SemGroup in both Canada (SemCanada Crude Company) and the U.S. (SemCrude LP). Deliveries in Canada subsequent to July 22, 2008 and in the U.S. subsequent to August 1, 2008 are on a prepaid basis. In accordance with our credit policies, Penn West had requested and received a $20 million parental guarantee from SemGroup. After reviewing the facts and sequence of events in this case, Penn West management has concluded that these events could not have been detected earlier by a standard credit risk program. During the third quarter of 2008, Penn West recorded an $18 million provision to write-off its entire receivable from SemGroup.

Interest Rate Risk

We currently maintain a portion of our debt capital in floating-rate bank facilities which results in exposure to fluctuations in short-term interest rates which have, for a number of years, been lower than longer-term rates. From time to time, we may increase the certainty of our future interest rates by entering fixed interest rate debt instruments or by using financial instruments to swap floating interest rates for fixed rates or to collar interest rates. For further details on these financial instruments, please refer to the Financing section of this MD&A.

The 2007 Notes, totalling US$475 million, bear fixed interest rates at an average rate of approximately 5.80 percent with an average term of 10.1 years subsequent to May 31, 2007. The 2008 Notes, which total US$480 million plus CAD$30 million, bear fixed interest rates at an average of approximately 6.25 percent with an average term of 9.6 years subsequent to May 29, 2008. The UK Notes, totalling (pnds stlg)57 million, have a fixed interest rate of approximately 7.78 percent for a term of 10 years. The Company entered into contracts to fix the principal and interest of the UK Notes at approximately $114 million bearing interest in Canadian dollars at 6.95 percent.

Liquidity Risk

Liquidity risk is the risk that Penn West is unable to meet its financial liabilities as they come due. Management utilizes a long-term financial and capital forecasting program that includes continuous review of debt forecasts to ensure credit facilities are sufficient relative to forecast debt levels, distribution and capital program levels are appropriate, and that financial covenants will be met. Management also regularly reviews capital markets to identify opportunities to optimize the debt capital structure on a cost effective basis. In the short term, liquidity is managed through daily cash management activities, short-term financing strategies and the use of collars and other financial instruments to increase the predictability of minimum levels of cash flow from operating activities. Additional information on specific instruments is discussed below in the "Liquidity and Capital Resources" section and in Note 5 to the unaudited interim consolidated financial statements.

    The following table outlines estimated future contractual obligations for
non-derivative financial liabilities as at December 31, 2008:

Environmental and Climate Change Risk

The oil and gas industry has a number of environmental risks and hazards and is subject to regulation by all levels of government. Environmental legislation includes, but is not limited to, operational controls, final site restoration requirements and increasing restrictions on emissions of various substances produced in association with oil and natural gas operations. Compliance with such legislation could require additional expenditures and a failure to comply may result in fines and penalties, which could in the aggregate become material. Penn West is currently injecting CO(2) at its enhanced oil recovery projects in amounts sufficient to offset its applicable carbon taxes.

Penn West is dedicated to reducing the environmental impact from our operations through our environmental program which includes resource conservation, stakeholder communication, CO(2) sequestration and site abandonment/reclamation. We fully understand our responsibilities of reducing the environmental impact from our operations and are committed to protecting the areas in which we operate.

During 2008, we paid total distributions, including those funded by the distribution reinvestment plan, of $1,500 million compared to distributions of $976 million for the comparable period in 2007. This increase was primarily due to approximately 124.3 million, 5.6 million and 3.6 million additional trust units issued to acquire Canetic and Vault in January 2008 as well as Endev in July 2008, respectively.

Long-term debt excluding convertible debentures at December 31, 2008 was $3,854 million, compared to $1,943 million at December 31, 2007. The increase was mainly due to debt of $1,443 million assumed in the Canetic acquisition and $114 million assumed in the Vault acquisition.

The working capital deficiency has declined from December 31, 2007 primarily due to the reduction in the current portion of the risk management liability.

The Company has unsecured, revolving, syndicated bank facilities totalling $4.0 billion with $2.6 billion drawn at year-end 2008 and senior unsecured notes of $1.3 billion. For further details on these debt instruments, please refer to the Financing section of this MD&A.

Over the past year, our Board and management team have closely monitored the credit issues occurring in the U.S. and other financial markets. As a result, Penn West has taken a number of actions to minimize these credit impacts, which include the new syndicated bank facility, long-term private notes, an "at-the-market distribution" facility and the issuance of equity. Additionally, we have an active risk management program to limit our exposure to credit risk and maintain close relationships with our bank syndicate members to monitor credit market developments. These actions aim to increase the likelihood of maintaining our capital and distribution programs and continuing our business strategies.

    On December 31, 2008, the Company was in compliance with all of the
financial covenants which include the following:
                                                                 December 31,

         convertible debentures that do not meet the requirements for equity

The 2008 Notes and the UK Notes contain change of control provisions requiring that if a change in control occurs, the Company may be required to offer to prepay the 2008 Notes and the UK Notes at par, which the holders of the 2008 Notes and the UK Notes have the right to refuse.

Under the terms of its current trust indenture, the Trust is required to make distributions to unitholders in amounts at least equal to its taxable income. Distributions may be monthly or special and in cash or in trust units at the discretion of our Board of Directors. To the extent that additional cash distributions are paid and capital programs are not adjusted, debt levels may increase. In the event that a special distribution in the form of trust units is declared, the terms of the current trust indenture require that the outstanding units be consolidated immediately subsequent to the distribution. The number of outstanding trust units would remain at the number outstanding immediately prior to the unit distribution, plus those sold to fund the payment of withholding taxes, and an amount equal to the distribution would be allocated to the unitholders as a taxable distribution. Penn West has never declared such a distribution and, at the current time, forecasts that such a special distribution will not be required for 2009.

Due to the extent of our environmental programs, we believe no benefit would arise from the initiation of a reclamation fund. We believe our program will be sufficient to meet or exceed existing environmental regulations and best industry practices. In the event of significant changes to the environmental regulations or the cost of environmental activities, a higher portion of funds flow would be required to fund our environmental expenditures.

Convertible Debentures

Penn West assumed the following convertible debentures through the Canetic acquisition, which closed on January 11, 2008 and the Vault acquisition, which closed on January 10, 2008. During the fourth quarter of 2008, PWT.DB.C debentures with a face value of $32 million (2007 - $nil) were redeemed by debenture holders and settled in cash.

    At December 31, 2008, the balance of our unsecured, subordinated

    (1)  Please refer to our discussion of productive capacity maintenance
         below.
    (2)  Consists of proceeds from the Distribution Reinvestment and Optional
         Purchase Plan, the Trust Unit Rights Incentive Plan and the Trust
         Unit Savings Plan.
    (3)  Represents cash distributions declared divided by standardized
         distributable cash.

We strive to fund both distributions and maintenance capital programs primarily from funds flow. We initially budget our capital programs at approximately 50-60 percent of annual forecast funds flow. We believe that proceeds from the Distribution Reinvestment and Optional Purchase Plan should be used to fund capital expenditures of a longer-term nature. Over the medium term, additional borrowings and equity issues may be required from time to time to fund a portion of our distributions, decrease or reallocate our leverage or maintain or increase our productive capacity. On a longer-term basis, adjustments to the level of distributions and/or capital expenditures to maintain or increase our productive capacity may be required based on forecast levels of funds flow, capital efficiency and debt levels. In January 2009, as a result of current market conditions and the low commodity price environment, we reduced our 2009 capital program and distribution level and closed the issuance of equity in February 2009.

Productive capacity maintenance is the amount of capital funds required in a period for an enterprise to maintain future cash flow from operating activities at a constant level. As commodity prices can be volatile and short-term variations in production levels are often experienced in our industry, we define our productive capacity as production on a barrel of oil equivalent basis. A quantifiable measure for these short-term variations is not objectively determinable or verifiable due to various factors including the inability to distinguish natural production declines from the effect of production additions resulting from capital and optimization programs, and the effect of temporary production interruptions. As a result, the adjustment for productive capacity maintenance in our calculation of standardized distributable cash is our capital expenditures during the period excluding the cost of any asset acquisitions or proceeds of any asset dispositions. We believe that our current capital programs, based on 50-60 percent of forecast annual funds flow and our current view of our assets and opportunities, including particularly our resource play assets, oil sands project, our proposed enhanced oil recovery projects, and our outlook for commodity prices and industry conditions, should be sufficient to maintain our productive capacity in the medium term. We set our hurdle rates for evaluating potential development and optimization projects according to these parameters. Due to the risks inherent in the oil and natural gas industry, particularly our exploration and development activities and variations in commodity prices, there can be no assurance that capital programs, whether limited to the excess of funds flow over distributions or not, will be sufficient to maintain or increase our production levels or cash flow from operating activities. Penn West historically incurred a larger proportion of its development expenditures in the first quarter of each calendar year to exploit winter-only access properties. As we strive to maintain sufficient credit facilities and appropriate levels of debt, this seasonality is not currently expected to influence our distribution policies.

Our calculation of standardized distributable cash has no adjustment for long-term unfunded contractual obligations. We believe our only significant long-term unfunded contractual obligation at this time is for asset retirement obligations. Cash flow from operating activities, used in our standardized distributable cash calculation, includes a deduction for abandonment expenditures incurred during each period. We believe that our current environmental programs will be sufficient to fund our asset retirement obligations over the life of our reserves. Our Board of Directors sets our distribution policies based on forecast funds flow and debt levels. Distributions in excess of net income may include an economic return of capital to unitholders.

We currently have no financing restrictions caused by our debt covenants. We regularly monitor our current and forecast debt levels to ensure debt covenants are not exceeded.

In October 2008, Penn West received approximately $123 million in cash as a result of monetizing a portion of crude oil financial contracts. This included lowering the floor on its 2009 WTI collars from US$85.00 per barrel to US$80.00 per barrel as well as monetizing all 2010 WTI collars. The proceeds were used to repay advances on our syndicated credit facility.

Outlook

This outlook section is included to provide unitholders with information as to our expectations as at February 18, 2009 for production and net capital expenditures for 2009 and readers are cautioned that the information may not be appropriate for any other purpose. This information constitutes forward-looking information. Readers should note the assumptions, risks and disclaimers under "Forward-Looking Statements".

We forecast our 2009 capital expenditures at between $600 million and $825 million. The reduction of our planned capital program in 2009 compared to 2008 reflects the current volatility in financial and commodity markets. In the first half of 2009, we anticipate spending between $250 million and $325 million based on current commodity price levels and industry costs. Our spending is limited in the first half as we expect industry service and other costs to decline and become more consistent with the current commodity price environment as we move through 2009. The 2009 capital program will be focused on low cost production recovery and additions through optimization and will continue the advancement of certain of our enhanced oil recovery projects and resource plays. Based on this level of capital expenditures, we forecast average production in the first half of 2009 to be approximately 180,000 boe per day prior to the effect of the 4,300 boe per day of property dispositions.

Our prior forecast, released on November 12, 2008 with our third quarter 2008 results and filed on SEDAR at www.sedar.com, was based on 2009 capital expenditures (excluding corporate acquisitions) between $600 million and $1.0 billion. Due to the extreme volatility in financial markets and the resulting decline in industry activity, no further guidance was provided at that time.

Sensitivity Analysis

Estimated sensitivities to selected key assumptions on reported financial results for the next 12 months, including risk management impacts, are outlined in the table below.

                                                        Impact on funds flow

    Liquids production             1,000 bbls/day              9        0.02
    Price per mcf of natural gas            $0.10              9        0.02
    Natural gas production            10 mmcf/day             12        0.03
    Effective interest rate                    1%              9        0.02
    Exchange rate ($US per $CAD)            $0.01             31        0.08
    -------------------------------------------------------------------------

    Based on December 31, 2008 pricing, a $1.00 change in the price per barrel
of liquids would change the pre-tax unrealized risk management gain by $12
million and a $0.10 change in the price per mcf of natural gas would change
the pre-tax unrealized risk management gain by $3 million.

    (2)  Future office lease commitments will be reduced by sublease
         recoveries totalling $387 million.

Our syndicated credit facility expires on January 11, 2011. If we were not successful in renewing or replacing the facility, we could be required to repay all amounts then outstanding on the facility or enter term bank loans. In addition, we have US$475 million of fixed-term notes expiring between 2015 and 2022, US$480 million and CAD$30 million of fixed-term notes expiring between 2016 and 2020 and (pnds stlg)57 million (swapped to approximately CAD$114 million) of fixed-term notes expiring in 2018. As we strive to maintain our leverage ratios at relatively modest levels, we believe we will be successful in renewing or replacing our credit facility on acceptable terms.

Convertible debentures with an aggregate principal amount of $296 million (2007 - $nil) outstanding on December 31, 2008, and a significant portion of the interest payable on convertible debentures may, at the option of the Trust, be settled by the issuance of trust units. For a schedule of convertible debenture maturities, please refer to the "Liquidity and Capital Resources" section of this MD&A and Note 6 to unaudited interim consolidated financial statements.

Disclosure Controls and Procedures

As of December 31, 2008, an internal evaluation was carried out of the effectiveness of the Trust's disclosure controls and procedures as defined in Rule 13a-15 under the US Securities Exchange Act of 1934 and as defined in Canada by National Instrument 52-109, Certification of Disclosure in Issuers' Annual and Interim Filings. Based on that evaluation, the Chief Executive Officer, the President and Chief Operating Officer and the Executive Vice President and Chief Financial Officer concluded that the disclosure controls and procedures are effective to ensure that the information required to be disclosed in the reports that the Trust files or submits under the Exchange Act or under Canadian Securities legislation is recorded, processed, summarized and reported, within the time periods specified in the rules and forms therein. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that the information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act or under Canadian Securities Legislation is accumulated and communicated to the Trust's management, including the senior executive and financial officers, as appropriate to allow timely decisions regarding the required disclosure.

Accounting Changes and Pronouncements

Effective January 1, 2008, the Trust adopted the new Canadian accounting standards "Capital Disclosures", "Financial Instruments - Disclosures" and "Financial Instruments - Presentation". The adoption of these standards had no material impact on the Trust's net income or cash flows from operating activities.

Capital Disclosures

This section outlines disclosures relating to the management of an entity's capital and additional qualitative and quantitative information on the objectives, policies and processes over capital.

Financial Instruments - Disclosures/Presentation

These sections outline more comprehensive disclosures with regard to risks related to financial instruments, the significance of financial instruments on an entity's financial position and performance, and the classification of financial instruments.

Future Accounting Pronouncements

In December 2008, the CICA issued a new accounting standard for "Business Combinations". This standard outlines new guidance which states that the purchase price is to be based on trading data at the closing date of the acquisition, not the announcement date of the acquisition, and that most acquisition costs are to be expensed as incurred. The new standard becomes effective on January 1, 2011 and early adoption is permitted. This standard will require the Trust to change its accounting policies for any new business combinations completed after the standard is adopted.

In February 2008, the CICA issued a new accounting standard for "Goodwill and Intangible Assets". This standard outlines guidelines for the recognition, measurement, presentation and disclosure of goodwill and intangible assets subsequent to their initial recognition. This new standard becomes effective January 1, 2009. The implementation of this section is expected to have no impact on the Trust's financial statements.

In January 2006, the Canadian Accounting Standards Board (the "AcSB") announced its decision to replace Canadian GAAP with International Financial Reporting Standards ("IFRS") for all Canadian Publicly Accountable Enterprises ("PAEs"), including Penn West. On February 13, 2008, the AcSB confirmed January 1, 2011 as the changeover date for PAEs to commence reporting under IFRS. Although IFRS is principles-based and uses a conceptual framework similar to Canadian GAAP, there are significant differences and choices in accounting policies, as well as increased disclosure requirements under IFRS.

We are currently assessing the impact of the conversion from Canadian GAAP to IFRS on our results of operations, financial position and disclosures. A project team and steering committee have been set up to manage this transition and to ensure successful implementation within the required timeframe. Employees involved in the project have attended a number of training courses and education sessions. Additionally, an external advisor has been engaged to assist with the implementation.

Communication is ongoing with many areas of the organization and regular updates are provided to senior management and the Audit committee. Based on work completed to date, the accounting differences that will lead to the largest changes include property, plant and equipment and business combinations. We will provide disclosures of the key elements of our plan and progress on the project as the information becomes available during the transition period.

Related-Party Transactions

During 2008, Penn West paid $5 million (2007 - $1 million) of legal fees to a law firm of which a partner is also a director of Penn West.

Off-Balance-Sheet Financing

We have off-balance-sheet financing arrangements consisting of operating leases. The material operating lease payments are summarized in the Contractual Obligations and Commitments section.

Critical Accounting Estimates

Our significant accounting policies are detailed in Note 2 to the unaudited interim consolidated financial statements. In the determination of financial results, we must make certain significant accounting estimates as follows:

Full Cost Accounting

We use the full cost method of accounting for oil and natural gas properties. All costs of exploring for and developing oil and natural gas reserves are capitalized and depleted against associated oil and natural gas production using the unit-of-production method based on the estimated proved reserves with forecast commodity pricing.

All of our reserves were evaluated or audited by GLJ Petroleum Consultants Ltd. ("GLJ") and Sproule Associates Limited ("SAL"), both independent engineering firms. Our reserves are determined in compliance with National Instrument 51-101. The evaluation of oil and natural gas reserves is, by its nature, based on complex extrapolations and models as well as other significant engineering, capital, pricing and cost assumptions. Reserve estimates are a key component in the calculation of depletion and are a key component of value in the ceiling test. To the extent that the ceiling amount, based in part on our reserves, is less than the carrying amount of property, plant and equipment, a "ceiling test" write-down against income must be made. We determined there was no ceiling test write-down required at December 31, 2008, for Canadian GAAP.

Asset Retirement Obligations

The discounted expected future cost of statutory, contractual or legal obligations to retire long-lived assets is recorded as an asset retirement liability with a corresponding increase to the carrying amount of the related asset. The recorded liability increases over time to its future liability amount through accretion charges to income, included in DD&A. Revisions to the estimated amount or timing of the obligations are reflected as increases or decreases to the recorded asset retirement obligation. Actual asset retirement expenditures are charged to the liability to the extent of the then-recorded liability. Amounts capitalized to the related assets are amortized to income consistent with the depletion or depreciation of the underlying asset. Note 7 to the unaudited interim consolidated financial statements details the impact of these accounting recommendations.

Financial Instruments

Financial instruments, included in the balance sheets consist of accounts receivable, fair values of derivative financial instruments, current liabilities (excluding future income tax liability), convertible debentures and long-term debt. Except for the senior notes and the convertible debentures, the fair values of these financial instruments approximate their carrying amounts due to the short-term maturity of the instruments, the mark to market values recorded for the financial instruments and the market rate of interest applicable to the bank debt. The estimated fair value of the senior notes and the convertible debentures is disclosed in Notes 5 and 6 to the unaudited interim consolidated financial statements.

Substantially all of our accounts receivable are with customers in the oil and natural gas industry and are subject to normal industry credit risk. We may, from time to time, use various types of financial instruments to reduce our exposure to fluctuating oil and natural gas prices, electricity costs, exchange rates and interest rates. The use of these financial instruments exposes us to credit risks associated with the possible non-performance of counterparties to the derivative contracts. We limit this risk by executing counterparty risk procedures which include transacting only with financial institutions with high credit ratings and obtaining security in certain circumstances.

Our revenues from the sale of crude oil, natural gas liquids and natural gas are directly impacted by changes to the underlying commodity prices. To ensure that funds flows are sufficient to fund planned capital programs and distributions, collars or other financial instruments may be utilized from time to time. Collars ensure that commodity prices realized will fall into a contracted range for a contracted sales volume. Forward power contracts fix a portion of future electricity costs at levels determined to be economic by management.

Goodwill

Goodwill must be recorded on a business combination when the total purchase consideration exceeds the fair value of the net identifiable assets and liabilities of the acquired entity. The goodwill balance is not amortized; however, it must be assessed for impairment at least annually. The goodwill impairment test consists of two parts. Under part 1, if the fair value of the reporting entity is less than its book value, part 2 of the test must be performed. As at December 31, 2008, due to the widespread decline in equity markets, Penn West proceeded to part 2 of the test where a reporting entity is required to calculate a purchase equation on its assets and liabilities at fair value on the balance sheet date. Under part 2, an equity control premium of 20 percent was used and the fair value of property, plant and equipment was estimated using forward strip commodity prices at year-end escalated at two percent per year subsequent to the end of available market data and a discount rate of 15 percent. Penn West determined there was no goodwill impairment at December 31, 2008.

A 1% change in the assumed control premium and a 1% change in the assumed discount rate applied to estimated cash flows change the fair value of Penn West by approximately $55 million and $350 million, respectively.

Forward-Looking Statements

In the interest of providing Penn West's unitholders and potential investors with information regarding Penn West, including management's assessment of Penn West's future plans and operations, certain statements contained in this document constitute forward-looking statements or information (collectively "forward-looking statements") within the meaning of the "safe harbour" provisions of applicable securities legislation. Forward-looking statements are typically identified by words such as "anticipate", "continue", "estimate", "expect", "forecast", "may", "will", "project", "could", "plan", "intend", "should", "believe", "outlook", "potential", "target" and similar words suggesting future events or future performance. In addition, statements relating to "reserves" or "resources" are deemed to be forward-looking statements as they involve the implied assessment, based on certain estimates and assumptions, that the reserves and resources described exist in the quantities predicted or estimated and can be profitably produced in the future.

In particular, this document contains forward-looking statements pertaining to, without limitation, the following: the ability of our capital program to increase our future exploration and development potential; our intention and ability to restore certain lost production and the timing thereof; our ability to mitigate the potential adverse consequences to our financial position, business strategy and capital and distribution programs that could result from the ongoing turmoil in the credit and financial markets; our 2009 capital expenditure levels, the timing of making said expenditures, and the key elements of our 2009 capital expenditure program; our expectation that services costs will decrease in the latter half of 2009; matters relating to our ongoing asset disposition program, including the timing for closing dispositions there under, the amount of proceeds to be derived therefrom and the use of such proceeds; the impact that the new Alberta royalty framework may have on us, including on our business strategies and plans; the nature and quality of our asset base and the opportunities to be derived therefrom; our intent and ability to improve our capital efficiency and implement operating and general and administrative cost efficiencies; our ability (financial and otherwise) to capitalize on opportunities that arise; our ability to fund our capital program and distributions with internally generated funds flow and proceeds from our distribution reinvestment program; our expectations regarding North American and global supply and demand factors for crude oil and natural gas in 2009 and beyond; the potential impact on our business, business strategies and plans, business model, future growth prospects, distribution policies and unitholders of the SIFT tax and the different actions that we might take in response to the SIFT tax and the potential impact those actions could have on us and our unitholders, including without limitation, our potential ability to shield our taxable income from income tax using our tax pools for a period of time following the implementation of the SIFT tax and the impact this would have on our distributions and unitholders; our ability to improve our finding and development cost performance; our intention and ability to maintain a balanced portfolio of liquids and natural gas production and the benefits we may derive therefrom; the nature and effectiveness of our risk management strategies; funding sources for distributions, distribution levels and whether a special distribution will be made in the future; our environmental regulation compliance costs and strategies, the sufficiency of our environmental program and our ability to fund our asset retirement obligations; our beliefs and outlook for the maintenance of our productive capacity in the medium term and the impact of seasonal factors on our distribution policies; the disclosure contained under the heading "Outlook", which sets forth management's expectations as to our net capital expenditures for 2009 and the timing for making said expenditures and the intended focus of such expenditures, our expectation that service costs will decrease as 2009 progresses, and our forecast average production in the first half of 2009; the sensitivity of our key assumptions regarding reported financial results relating to funds flow and pre-tax unrealized risk management gains for the next 12 months to changes in certain operational and financial metrics; our belief that we will be successful in renewing or replacing our credit facilities on acceptable terms when they mature; and our expectations regarding the impact that new and pending accounting changes may have on us.

With respect to forward-looking statements contained in this document, we have made assumptions regarding, among other things: future oil and natural gas prices and differentials between light, medium and heavy oil prices; future capital expenditure levels; future oil and natural gas production levels; future exchange rates and interest rates; the amount of future cash distributions that we intend to pay; our ability to obtain equipment in a timely manner to carry out development activities; our ability to market our oil and natural gas successfully to current and new customers; the impact of increasing competition; our ability to obtain financing on acceptable terms; and our ability to add production and reserves through our development and exploitation activities. In addition, many of the forward-looking statements contained in this document are located proximate to assumptions that are specific to those forward-looking statements, and such assumptions should be taken into account when reading such forward-looking statements: see in particular the assumptions identified under the headings "Financial Markets", "Enactment of the Tax on Income Trusts", "Standardized Distributable Cash", "Outlook" and "Sensitivity Analysis".

Although Penn West believes that the expectations reflected in the forward-looking statements contained in this document, and the assumptions on which such forward-looking statements are made, are reasonable, there can be no assurance that such expectations will prove to be correct. Readers are cautioned not to place undue reliance on forward-looking statements included in this document, as there can be no assurance that the plans, intentions or expectations upon which the forward-looking statements are based will occur. By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties that contribute to the possibility that the predictions, forecasts, projections and other forward-looking statements will not occur, which may cause Penn West's actual performance and financial results in future periods to differ materially from any estimates or projections of future performance or results expressed or implied by such forward-looking statements. These risks and uncertainties include, among other things: the impact of weather conditions on seasonal demand and ability to execute capital programs; risks inherent in oil and natural gas operations; uncertainties associated with estimating reserves and resources; competition for, among other things, capital, acquisitions of reserves, resources, undeveloped lands and skilled personnel; incorrect assessments of the value of acquisitions; geological, technical, drilling and processing problems; general economic conditions in Canada, the U.S. and globally; industry conditions, including fluctuations in the price of oil and natural gas; royalties payable in respect of our oil and natural gas production; changes in government regulation of the oil and natural gas industry, including environmental regulation; fluctuations in foreign exchange or interest rates; unanticipated operating events that can reduce production or cause production to be shut-in or delayed; failure to obtain industry partner and other third-party consents and approvals when required; stock market volatility and market valuations; OPEC's ability to control production and balance global supply and demand of crude oil at desired price levels; political uncertainty, including the risks of hostilities, in the petroleum producing regions of the world; the need to obtain required approvals from regulatory authorities from time to time; failure to realize the anticipated benefits of acquisitions, including the acquisitions; changes in tax laws; changes in the Alberta royalty framework; uncertainty of obtaining required approvals for acquisitions and mergers; and the other factors described under "Business Risks" in this document and in Penn West's public filings (including our Annual Information Form) available in Canada at www.sedar.com and in the United States at www.sec.gov. Readers are cautioned that this list of risk factors should not be construed as exhaustive.

The forward-looking statements contained in this document speak only as of the date of this document. Except as expressly required by applicable securities laws, Penn West does not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The forward-looking statements contained in this document are expressly qualified by this cautionary statement.

    Notes to the Unaudited Interim Consolidated Financial Statements
    (All tabular amounts are in millions except numbers of units, per unit
    amounts, percentages and various figures in Note 10)

    1.  Structure of Penn West

    Penn West Energy Trust ("Penn West" or the "Trust") is an open-ended,
    unincorporated investment trust governed by the laws of the Province of
    Alberta. The business of Penn West is to indirectly explore for, develop
    and hold interests in petroleum and natural gas properties through
    investments in securities of subsidiaries and royalty interests in oil
    and natural gas properties. Penn West owns 100 percent of the equity,
    directly or indirectly, of the entities that carry on the oil and natural
    gas business of Penn West. The activities of these entities are financed
    through interest-bearing notes from Penn West and third-party debt as
    described in the notes to the unaudited interim consolidated financial
    statements.

    Pursuant to the terms of net profit interest agreements (the "NPIs"),
    Penn West is entitled to payments from certain subsidiary entities equal
    to essentially all of the proceeds of the sale of oil and natural gas
    production less certain deductions. Under the terms of the NPIs, the
    deductions are in part discretionary, include the requirement to fund
    capital expenditures and asset acquisitions, and are subject to certain
    adjustments for asset dispositions.

    Under the terms of its current trust indenture, Penn West is required to
    make distributions to unitholders in amounts at least equal to its
    taxable income consisting of interest on notes, the NPIs, and any inter-
    corporate distributions and dividends received, less certain expenses and
    deductions.

    2.  Significant accounting policies and basis of presentation

    These unaudited interim consolidated financial statements have been
    prepared in accordance with Canadian generally accepted accounting
    principles and are consistent with the accounting policies described in
    the notes to the audited consolidated financial statements of Penn West
    for the year ended December 31, 2007, except as described below. These
    financial statements do not include all of the disclosures outlined in
    Penn West's annual financial statements and should accordingly be read in
    conjunction with Penn West's audited consolidated financial statements
    and notes thereto for the year ended December 31, 2007.

    Effective January 1, 2008, the Trust adopted the new Canadian accounting
    standards "Capital Disclosures", "Financial Instruments - Disclosures"
    and "Financial Instruments - Presentation". The adoption of these
    standards had no material impact on the Trust's net income or cash flow
    from operating activities.

    Capital Disclosures

    This section outlines disclosures relating to the management of an
    entity's capital and additional qualitative and quantitative information
    on the objectives, policies and processes over capital.

    Financial Instruments - Disclosures / Presentation

    These sections outline more comprehensive disclosures with regard to
    risks related to financial instruments, the significance of financial
    instruments on an entity's financial position and performance, and the
    classification of financial instruments.

    Financial Instruments

    Convertible debentures are designated as other financial liabilities.

    Per Unit Calculations

    Penn West follows the "if converted" method to compute the dilutive
    impact of the convertible debentures which assumes the outstanding
    debentures have been converted at the beginning of the period or upon
    issuance, if later.

    Future Accounting Pronouncements

    In December 2008, the CICA issued a new accounting standard for "Business
    Combinations". This standard outlines new guidance which states that the
    purchase price is to be based on trading data at the closing date of the
    acquisition, not the announcement date of the acquisition, and that most
    acquisition costs are to be expensed as incurred. The new standard
    becomes effective on January 1, 2011 and early adoption is permitted.
    This standard will require the Trust to change its accounting policies
    for any new business combinations completed after the standard is
    adopted.

    In February 2008, the CICA issued a new accounting standard for "Goodwill
    and Intangible Assets". This standard outlines guidelines for the
    recognition, measurement, presentation and disclosure of goodwill and
    intangible assets subsequent to their initial recognition. This new
    standard becomes effective January 1, 2009. The implementation of this
    section is expected to have no impact on the Trust's financial
    statements.

    In January 2006, the Canadian Accounting Standards Board (the "AcSB")
    announced its decision to replace Canadian GAAP with International
    Financial Reporting Standards ("IFRS") for all Canadian Publicly
    Accountable Enterprises ("PAEs"), including Penn West. On February 13,
    2008, the AcSB confirmed January 1, 2011 as the changeover date for PAEs
    to commence reporting under IFRS. Although IFRS is principles-based and
    uses a conceptual framework similar to Canadian GAAP, there are
    significant differences and choices in accounting policies, as well as
    increased disclosure requirements under IFRS.

    We are currently assessing the impact of the conversion from Canadian
    GAAP to IFRS on our results of operations, financial position and
    disclosures. A project team and steering committee have been set up to
    manage this transition and to ensure successful implementation within the
    required timeframe. Employees involved in the project have attended a
    number of training courses and education sessions. Additionally, an
    external advisor has been engaged to assist with the implementation.

    Communication is ongoing with many areas of the organization and regular
    updates are provided to senior management and the Audit committee. Based
    on work completed to date, the accounting differences that will lead to
    the largest changes include property, plant and equipment and business
    combinations. We will provide disclosures of the key elements of our plan
    and progress on the project as the information becomes available during
    the transition period.

    3.  Business combinations

    Canetic Acquisition

    On January 11, 2008, Penn West closed its acquisition of Canetic
    Resources Trust ("Canetic") for a total acquisition cost of approximately
    $3.6 billion, funded through the issuance of approximately 124.3 million
    trust units, calculated based on the volume weighted average trading
    price of the units around the date of the announcement, discounted by
    five percent. The acquisition by Penn West was accounted for using the
    purchase method of accounting. The final allocation of the consideration
    paid to the fair value of the identifiable assets and liabilities was as
    follows:

    Purchase price
    -------------------------------------------------------------------------
    124.3 million Penn West trust units issued                    $    3,573

    -------------------------------------------------------------------------

    Vault Acquisition

    On January 10, 2008, Penn West closed its acquisition of Vault Energy
    Trust ("Vault") for a total acquisition cost of approximately $164
    million funded through the issuance of approximately 5.6 million trust
    units. The trust unit value was calculated based on the volume weighted
    average trading price of the units around the date of the announcement,
    discounted by five percent. The acquisition by Penn West was accounted
    for using the purchase method of accounting. The final allocation of the
    consideration paid to the fair value of the identifiable assets and
    liabilities was as follows:

    Purchase price
    -------------------------------------------------------------------------
    5.6 million Penn West trust units issued                      $      158

    Endev Acquisition

    On July 22, 2008, the acquisition of Endev Energy Inc. ("Endev") was
    successfully completed. As a result of the acquisition, Penn West issued
    approximately 3.6 million trust units for a total consideration of $115
    million and assumed approximately $45 million of debt and working
    capital. The acquisition was accomplished through a Plan of Arrangement
    wherein Endev shareholders received 0.041 of a Penn West trust unit for
    each Endev share.

    4.  Property, plant and equipment
                                                           As at December 31
    -------------------------------------------------------------------------
                                                            2008        2007

    -------------------------------------------------------------------------

    Other than Penn West's net share of capital overhead recoveries, no
    general and administrative expenses are capitalized. In 2008, additions
    to property, plant and equipment included a $25 million (2007 - $97
    million) increase related to additions to asset retirement obligations
    and $11 million (2007 - $5 million) was recorded for future income taxes
    on minor property acquisitions.

    An impairment test was performed on the costs capitalized to oil and
    natural gas properties at December 31, 2008 and 2007. The estimated
    undiscounted future net funds flows from proved reserves, using forecast
    prices, exceeded the carrying amount of the oil and natural gas property
    interests less the cost of unproved properties.

    5.  Long-term debt

    At December 31, 2008, Penn West Petroleum Ltd. (the "Company") had an
    unsecured, revolving, three-year syndicated bank facility with an
    aggregate borrowing limit of $4.0 billion expiring on January 11, 2011.
    The facility consists of two revolving tranches; tranche one of the
    facility is $3.25 billion and extendible and tranche two is $750 million
    and non-extendible. The credit facility contains provisions for stamping
    fees on bankers' acceptances and LIBOR loans and standby fees on
    unutilized credit lines that vary depending on certain consolidated
    financial ratios. As at December 31, 2008, approximately $1.4 billion of
    unused credit capacity was available.

    Letters of credit totalling $1 million were outstanding on December 31,
    2008 (December 31, 2007 - $nil) that reduced the amount otherwise
    available to be drawn on the syndicated facility.

    Financing costs including interest expense on the syndicated credit
    facility, the senior unsecured notes and convertible debentures were $53
    million for the fourth quarter of 2008 (2007 - $27 million) and $204
    million for the year ended December 31, 2008 (2007 - $93 million).

    The US$475 million senior unsecured notes (the "2007 Notes") are subject
    to the financial covenant that consolidated total debt to consolidated
    capitalization shall not exceed 55 percent except in the event of a
    material acquisition where it is not to exceed 60 percent. The estimated
    fair value of the principal and interest obligations under the notes at
    December 31, 2008 was $495 million (December 31, 2007 - $458 million).

    On May 29, 2008, the Company closed the issuance of senior unsecured
    notes (the "2008 Notes"), on a private placement basis primarily in the
    United States, with aggregate principal amounts of US$480 million plus
    CAD$30 million. The 2008 Notes will mature in eight years to 12 years and
    bear interest at rates between 6.12 percent and 6.40 percent with an
    average rate of approximately 6.25 percent and an average term of 9.6
    years. The 2008 Notes contain covenants on total debt to capitalization,
    total debt to income before interest, taxes and depreciation and
    depletion ("EBITDA"), set priority debt limitations and contain change of
    control provisions. The estimated fair value of the principal and
    interest obligations under the notes at December 31, 2008 was $536
    million (December 31, 2007 - n/a).

    On July 31, 2008, the Company issued (pnds stlg)57 million of senior,
    unsecured notes (the "UK Notes") through a private placement in the
    United Kingdom maturing in 2018 and bearing interest of 7.78 percent. In
    conjunction with the issue of these notes, the Company entered into
    contracts to fix the principal and interest payments at approximately
    $114 million bearing interest in Canadian dollars at 6.95 percent. The
    financial covenants of the UK Notes are similar to the 2008 Notes. The
    estimated fair value of the principal and interest obligations under the
    notes at December 31, 2008 was $92 million (December 31, 2007 - n/a).

    6.  Convertible debentures

    Penn West assumed the following unsecured subordinated convertible
    debentures through the Canetic acquisition closing on January 11, 2008
    and the Vault acquisition closing on January 10, 2008 as discussed in
    Note 3. On the assumption of the convertible debentures, no amount was
    allocated to the fair value of the equity conversion features.

    convertible debentures at December 31, 2008, based on quoted market value
    was $248 million.

    7.  Asset retirement obligations

    The total estimated inflated and undiscounted amount to settle Penn
    West's asset retirement obligations at December 31, 2008 was $4.2 billion
    (December 31, 2007 - $2.6 billion). The asset retirement obligation was
    determined by applying an inflation factor of 2.0 percent (2007 - 2.0
    percent) and the inflated amount was discounted using credit-adjusted
    rates between 7.0 - 9.0 percent (2007 - 7.0 percent) over the expected
    useful life of the underlying assets, currently extending up to 50 years
    into the future with an average life of 24 years. Future cash flows from
    operating activities are expected to fund these obligations.

    Changes to asset retirement obligations were as follows:

    -------------------------------------------------------------------------

    For the year ended December 31, 2008, 13.5 million trust unit rights
    (2007 - 2.1 million) and 0.6 million units that would be issued on the
    conversion of the convertible debentures (2007 - nil) were excluded in
    calculating the weighted average number of diluted trust units
    outstanding as they were considered anti-dilutive. At December 31, 2008,
    as a portion of the convertible debentures are considered dilutive, the
    corresponding interest expense of $12 million for the year ended 2008
    (2007 - $nil) is excluded from the earnings per share calculation.

    In June 2008, the Company completed all requirements to enable the sale
    of trust units by way of "at-the-market distributions" on both the TSX
    and the NYSE. Penn West may issue and sell up to 20,000,000 trust units
    from time to time at its discretion during a period of up to 25 months.
    The trust units will be distributed at the current market price at the
    time of sale. The net proceeds from the sale of trust units under the
    facility, if any, will be used to repay debt or fund future growth
    opportunities. At December 31, 2008 no units had been issued under the
    facility.

    9.  Unit-based compensation

    Trust unit rights incentive plan

    Penn West has a unit rights incentive plan that allows Penn West to issue
    rights to acquire trust units to directors, officers, employees and other
    service providers. Under the terms of the plan, the number of trust units
    reserved for issuance shall not exceed 10 percent of the aggregate number
    of issued and outstanding trust units of Penn West. Unit rights are
    granted at prices administered to be equal to the volume-weighted average
    trading price of the trust units on the Toronto Stock Exchange for the
    five trading days immediately prior to the date of grant. If certain
    conditions are met, the exercise price per unit may be reduced by
    deducting from the grant price the aggregate of all distributions, on a
    per unit basis, paid by Penn West after the grant date. Rights granted
    under the plan prior to November 13, 2006 vest over a five-year period
    and expire six years after the date of the grant. Rights granted
    subsequent to this date generally vest over a three-year period and
    expire four years after the date of the grant.

    Penn West recorded unit-based compensation expense of $45 million for the
    year ended December 31, 2008, of which $11 million was charged to
    operating expense and $34 million was charged to general and
    administrative expense (2007 - $21 million, $6 million and $15 million
    respectively). Unit-based compensation expense is based on the fair value
    of rights issued and is amortized over the remaining vesting periods on a
    straight-line basis.

    The Binomial Lattice option-pricing model was used to determine the fair
    value of trust unit rights granted with the following weighted average
    assumptions:

    Trust unit savings plan

    Penn West has an employee trust unit savings plan for the benefit of all
    employees. Under the savings plan, employees may elect to contribute up
    to 10 percent of their salary and Penn West matches these contributions
    at a rate of $1.50 for each $1.00. Both the employee's and Penn West's
    contributions are used to acquire Penn West trust units. These trust
    units may be issued from treasury at the five-day volume weighted average
    month-end trading price on the Toronto Stock Exchange or purchased in the
    open market at prevailing market prices.

    10. Risk management

    Financial instruments, included in the balance sheets consist of accounts
    receivable, fair values of derivative financial instruments, current
    liabilities (excluding future income tax liability), convertible
    debentures and long-term debt. Except for the U.S. Senior notes and the
    UK notes described in Note 5 and the convertible debentures described in
    Note 6, the fair values of these financial instruments approximate their
    carrying amounts due to the short-term maturity of the instruments, the
    mark to market values recorded for the financial instruments and the
    market rate of interest applicable to the bank debt.

    A detailed discussion of the key business risks faced by Penn West, which
    includes market risk, commodity price risk, foreign currency rate risk,
    credit risk, interest rate risk and liquidity risk, is included in the
    accompanying Management's Discussion and Analysis under the heading
    "Business Risks". The disclosure under this heading is hereby
    incorporated by reference into, and forms an integral part of, these
    financial statements. A quantitative analysis of risks is included in the
    Management's Discussion and Analysis under the heading "Sensitivity
    Analysis".

    Changes in the fair value of all outstanding financial commodity, power,
    interest rate and foreign exchange contracts are reflected on the balance
    sheets with a corresponding unrealized gain or loss included in income.

    In October 2008, Penn West received approximately $123 million in cash as
    a result of monetizing a portion of crude oil financial contracts. This
    included lowering the floor on its 2009 WTI collars from US$85.00 per
    barrel to US$80.00 per barrel as well as monetizing all 2010 WTI collars.
    The proceeds were used to repay advances on our syndicated credit
    facility.

    A realized gain of $6 million (2007 - $11 million) on electricity
    contracts has been included in operating costs.

    Realized gains and losses on the interest rate swaps are charged to
    interest expense. In the period, the fixed rate and the floating rate
    were approximately equal resulting in no reportable gain or loss being
    charged to interest rate expense in relation to the interest rate swaps.

    11. Income taxes

    As at December 31, 2008, the total future income tax liability of $1,500
    million (December 31, 2007 - $873 million) consisted of a $132 million
    current future income tax liability (December 31, 2007 - $45 million
    current future income tax asset) and a $1,368 million long-term future
    income tax liability (December 31, 2007 - $918 million). The significant
    increase from the prior year is due primarily to future taxes recognized
    on the Canetic acquisition of $511 million and $198 million attributable
    to the unrecognized risk management gain for the year of $661 million.

    The current portion of the future income tax liability represents income
    taxes attributable to the unrealized risk management asset of $448
    million.

    On June 12, 2007, the Government of Canada enacted new tax legislation on
    publicly traded income trusts, effective for the 2011 tax year. As a
    result of the enactment, an additional $326 million future income tax
    liability and future income tax expense was recorded in the second
    quarter of 2007 to reflect the Trust's temporary differences between the
    accounting and tax values of assets and liabilities expected to be
    remaining in 2011. In accordance with GAAP, prior to the enactment, the
    Trust's temporary differences were not recorded as future income taxes.
    The majority of the temporary differences at the Trust level arose on the
    Petrofund acquisition that closed on June 30, 2006.

    12. Capital management

    The Trust manages its capital to provide a flexible structure to support
    its growth and operational strategies while maintaining a strong
    financial position in order to capture business opportunities and
    maintain a stable distribution profile to its unitholders.

    Penn West defines unitholders equity, long-term debt and convertible
    debentures as capital. Unitholders' equity includes unitholders' capital,
    contributed surplus and retained earnings. Long-term debt includes
    drawings on our syndicated bank facility, the 2007 Notes, the 2008 Notes
    and the UK Notes.

    Management continuously reviews its capital structure to ensure it is
    appropriate given the objectives and strategies of the Trust. The capital
    structure is reviewed based on a number of key factors including, but not
    limited to, the current market conditions, trailing and forecast debt to
    equity ratios and debt to funds flow and other economic risk factors
    identified by the Trust. Under the terms of its current trust indenture,
    the Trust is required to make distributions to unitholders in amounts at
    least equal to its taxable income. Distributions may be monthly or
    special and in cash or in trust units at the discretion of our Board of
    Directors.

    In January 2008, Penn West closed its acquisition of Canetic through the
    issuance of approximately 124.3 million trust units for a total
    acquisition cost of $3.6 billion and assumed $1.7 billion of long-term
    debt and convertible debentures. In addition, Penn West closed its
    acquisition of Vault in January 2008 issuing approximately 5.6 million
    trust units for a total acquisition cost of $164 million and assumed $213
    million of long-term debt and convertible debentures. In July 2008, Penn
    West closed its acquisition of Endev through the issuance of
    approximately 3.6 million trust units for a total acquisition cost of
    $115 million and assumed $43 million of long-term debt. These
    transactions led to a material increase in recorded unitholders' equity.

    The Company is subject to certain financial covenants under its
    unsecured, syndicated credit facility and the 2007 Notes, the 2008 Notes
    and the UK Notes. As at December 31, 2008, the Company was in compliance
    with all financial covenants as follows:
