Penn West Announces Its Results for the Fourth Quarter Ended December 31, 2010

Thursday, February 17, 2011

Penn West Announces Its Results for the Fourth Quarter Ended December 31, 201006:30 EST Thursday, February 17, 2011CALGARY, ALBERTA--(Marketwire - Feb. 17, 2011) - PENN WEST EXPLORATION (TSX:PWT) (NYSE:PWE) is pleased to announce its results for the fourth quarter ended December 31, 2010As we move forward as an exploration and production ("E&P") company, our objective is to deliver both growth and dividends to our shareholders. To this end, our aim in 2010 was to appraise the potential of our light-oil resource plays and to position other significant Penn West resources for future large-scale development using joint ventures. We believe we are well positioned as we increase our capital focus on the key strengths of our asset base.Financial Results- Funds flow (1) of $305 million in the fourth quarter of 2010 increased 14 percent from the $267 million realized in the third quarter of 2010. Basic funds flow increased to $0.67 per unit (1) in the fourth quarter of 2010 from $0.59 per unit in the third quarter of 2010, primarily from higher production and crude oil prices.- Funds flow for 2010 totalled $1,185 million compared to $1,493 million in 2009 reflecting the sale of properties and lower realized risk management gains.- Net income for 2010 totalled $226 million ($0.51 per unit-basic) compared to a net loss of $144 million ($0.35 per unit-basic) in 2009 as a result of higher oil and natural gas revenues and lower unrealized risk management losses.- Net debt (1) was reduced by approximately $536 million (2) during 2010 to $3.1 billion at December 31, 2010 due to the proceeds received from an asset exchange, an equity issue, the Peace River Oil Partnership transaction and the Cordova Joint Venture.- The netback (1) of $25.34 per boe in the fourth quarter of 2010 was 10 percent higher than the third quarter of 2010 mainly due to stronger crude oil prices.Operations- Our results to date from appraising our large, light-oil resource plays are generally on-track with our expectations and led us to increase our activity levels as we move into 2011.- In 2010, we drilled 319 net wells, including 245 net oil wells, 38 net natural gas wells and 34 net stratigraphic and service wells.- Fourth quarter 2010 production increased to 166,148 boe (3) per day from 164,087 boe per day in the third quarter of 2010 reflecting drilling success. Production for the fourth quarter included 88,447 barrels per day of light oil and NGLs, 16,849 barrels per day of heavy oil and 365 mmcf per day of natural gas.- Production for 2010 averaged 164,633 boe per day. Exit production at December 31, 2010 was approximately 167,100 boe per day. Apportionment issues on certain Enbridge pipelines reduced year-end exit production by approximately 1,900 boe per day.- Capital expenditures, net, for 2010 totalled $1,187 million including $102 million of strategic land acquisitions. Capital expenditures, net, were $400 million in the fourth quarter of 2010 compared to $196 million in the fourth quarter of 2009. We began escalating drilling levels in the fall of 2010 and have further increased activity during the first quarter of 2011.(1) The terms "funds flow", "funds flow per unit-basic", "netback" and "net debt" are non-GAAP measures. Please refer to the "Calculation of Funds Flow", "Highlights - Netback per boe", "Results of Operations - Netbacks" and "Non-GAAP Measures Advisory" sections below.(2) Consists of the change in long-term debt, convertible debentures and working capital (excluding future income taxes and risk management). Please refer to the Consolidated Balance Sheets below.(3) Please refer to the "Oil and Gas Information Advisory" section below for information regarding the term "boe".- We continue to appraise the resource potential of our extensive portfolio. We are the most active driller in the Western Canadian Sedimentary Basin with 31 rigs currently running.- The Enbridge apportionment issues continue to the present. In early January 2011, issues at a partner operated gas facility in the Swan Hills area resulted in the loss of approximately 3,500 boe per day. We are optimistic our production will be restored in the near future. Penn West is maintaining original guidance in the range of 172,000 - 177,000 boe per day as we are confident that we can overcome the shortfalls that have been beyond our control.Reserves Highlights- Total working interest proved reserves were 481 mmboe and total working interest proved plus probable reserves were 661 mmboe at December 31, 2010, weighted approximately 70 percent to crude oil and liquids and 30 percent to natural gas.- Adjusted finding, development and acquisition costs ("FD&A") (1) on a proved plus probable basis, including the change in future development capital were $18.12 per boe for 2010 (2009 - $23.77 per boe).- In 2010, we added approximately 72 million boe of reserves on a proved plus probable basis with approximately 68 percent related to crude oil and liquids.2011 Capital Strategy- As we move into 2011, we will continue our focus on light-oil appraisal and full-scale development. Our exploration and development capital program for 2011 will be approximately 90 percent focused on light-oil projects using horizontal multi-stage fracture technology. We will continue to evaluate ongoing drilling results with a concentration on projects with the size and potential to drive growth in both production and reserves.- The 2011 capital program will focus on our large resource plays in the Cardium in Alberta, the Colorado Viking in Alberta and Saskatchewan, Waskada in Manitoba and the Carbonates in northern Alberta. The 2011 plan also includes accelerating the appraisal of our heavy oil interests in the Peace River Oil Partnership and our unconventional natural gas assets located in the Cordova Embayment.Risk Management Activity- Since September 30, 2010, we entered into additional crude oil collars on 20,000 barrels per day for 2012 at US$84.25 per barrel to US$98.45 per barrel.Dividends- We have adopted a dividend policy with an expected initial quarterly dividend of $0.27 per share. The dividend is subject to the approval of our Board of Directors based on the outlook for commodity prices, production levels and planned capital programs. We anticipate the first quarterly dividend to be declared payable on April 15, 2011 to shareholders of record on March 31, 2011.Corporate Update- On January 1, 2011, we converted to a growth oriented, dividend paying, E&P company. We now operate under the trade name Penn West Exploration.- On January 4, 2011, we completed the closing of a private placement of notes for a principal amount of approximately US$230 million with an average term of 10.8 years and an average interest rate of 5.00 percent.- On January 26, 2011, due to our corporate conversion, we announced our offer to repurchase all of our outstanding convertible debentures. Debenture holders are entitled to receive cash consideration based on the offer prices with the offer closing on March 3, 2011. At January 26, 2011, we had approximately $255 million of convertible debentures outstanding.(1) Refer to "finding and development costs" table below for discussion on Adjusted FD&A.HIGHLIGHTS Three months ended Year ended December 31 December 31 ---------------------------------------------------- % % 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Financial(millions, exceptper unit amounts)Gross revenues (1) $ 782 $ 831 (6) $ 3,034 $ 3,203 (5)Funds flow 305 366 (17) 1,185 1,493 (21) Basic per unit 0.67 0.87 (23) 2.68 3.62 (26) Diluted per unit 0.66 0.86 (23) 2.65 3.60 (26)Net income (loss) (21) (12) 75 226 (144) 100 Basic per unit (0.05) (0.03) 67 0.51 (0.35) 100 Diluted per unit (0.05) (0.03) 67 0.50 (0.35) 100Capitalexpenditures, net (2) 400 196 100 1,187 688 73Long-term debt at period-end 2,496 3,219 (22) 2,496 3,219 (22)Convertible debentures 255 273 (7) 255 273 (7)Distributions paid (3) $ 123 $ 189 (35) $ 708 $ 910 (22)Payout ratio (4) 40% 52% (12) 60% 61% (1)OperationsDaily average production Light oil and NGL (bbls/d) 88,447 77,627 14 80,706 78,011 3 Heavy oil (bbls/d) 16,849 24,009 (30) 18,260 25,962 (30) Natural gas (mmcf/d) 365 411 (11) 394 440 (10)----------------------------------------------------------------------------Total production (boe/d) 166,148 170,164 (2) 164,633 177,221 (7)----------------------------------------------------------------------------Average sales price Light oil and NGL (per bbl) $ 71.05 $ 69.49 2 $ 69.29 $ 59.07 17 Heavy oil (per bbl) 61.87 62.97 (2) 60.55 53.75 13 Natural gas (per mcf) 3.79 4.39 (14) 4.20 4.13 2Netback per boe Sales price $ 52.43 $ 51.19 2 $ 50.74 $ 44.11 15 Risk management gain (loss) (1.51) 1.89 (100) (0.34) 5.32 (100)---------------------------------------------------------------------------- Net sales price 50.92 53.08 (4) 50.40 49.43 2 Royalties (9.14) (9.35) (2) (9.07) (7.66) 18 Operating expenses (15.92) (15.10) 5 (15.71) (14.93) 5 Transportation (0.52) (0.52) - (0.55) (0.52) 6---------------------------------------------------------------------------- Netback $ 25.34 $ 28.11 (10) $ 25.07 $ 26.32 (5)----------------------------------------------------------------------------(1) Gross revenues include realized gains and losses on commodity contracts.(2) Excludes net proceeds on property acquisitions and dispositions and business combinations.(3) Includes distributions paid prior to those reinvested in trust units under the distribution reinvestment plan.

Of total proved reserves, 86 percent were developed at December 31, 2010 compared to 88 percent at December 31, 2009. At December 31, 2010 total proved reserves as a percentage of proved plus probable reserves were 73 percent consistent with the prior year. In 2010, all of our reserves were evaluated or audited by independent engineering firms GLJ Petroleum Consultants Ltd. ("GLJ") or Sproule Associates Limited ("SAL"). Approximately 10 percent of total proved plus probable reserves were internally evaluated and audited by our independent qualified reserve evaluators.GLJ and SAL are our independent qualified reserves evaluators. The reserves 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 reserves 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 equal to or greater than the proved plus probable reserves estimate. The reserves estimates set forth above are estimates only and there is no guarantee that the estimated reserves will be recovered. Actual reserves may be greater than or less than the estimates provided herein.Additional reserve disclosures, as required under NI 51-101, will be contained in our Annual Information Form that will be filed on SEDAR at www.sedar.com.c) Reconciliation of Working Interest Reserves using forecast prices and costs Light and Medium Oil and Natural Gas Liquids Heavy Oil (mmbbl) (mmbbl) ------------------------------------------------------------- Proved ProvedReconciliation plus plus Items (1) Proved Probable probable Proved Probable probable----------------------------------------------------------------------------December 31, 2009 285 116 401 56 15 71Extensions 15 6 21 - - -Improved Recovery 2 (1) 1 1 - 1Infill Drilling 9 5 14 1 - 1Technical Revisions 10 (3) 7 2 - 2Discoveries - - - - - -Acquisitions 10 4 13 3 2 5Dispositions (18) (22) (41) (3) (2) (4)Economic Factors (1) - (1) (1) (1) (2)Production (29) - (29) (7) - (7)----------------------------------------------------------------------------December 31, 2010 283 103 387 54 14 68---------------------------------------------------------------------------- Natural Gas Barrels of Oil Equivalent (bcf) (mmboe) ------------------------------------------------------------- Proved ProvedReconciliation plus plus Items (1) Proved Probable probable Proved Probable probable----------------------------------------------------------------------------December 31, 2009 938 354 1,292 497 190 687Extensions 46 49 95 23 14 38Improved Recovery 3 - 3 4 (1) 3Infill Drilling 9 3 12 12 5 17Technical Revisions 59 (30) 29 22 (8) 14Discoveries - - - - - -Acquisitions 27 12 39 17 8 25Dispositions (48) (9) (58) (29) (26) (55)Economic Factors (27) (9) (36) (6) (3) (9)Production (141) - (141) (59) - (59)----------------------------------------------------------------------------December 31, 2010 865 370 1,235 481 179 661----------------------------------------------------------------------------(1) Columns may not add due to rounding.We increased our capital program during 2010 in preparation for our change to a growth oriented E&P company. Throughout 2010, we were active in consolidating our resource base through a number of acquisition, divestiture and land transactions. We closed three significant transactions, an asset exchange in the first quarter, the Peace River Oil Partnership in the second quarter and the Cordova Joint Venture in the third quarter. The asset exchange was consistent with our strategy of moving our assets from the early assessment stage through the development stage while considering our asset portfolio balance. The latter two transactions involved us contributing assets and retaining an ownership interest and operatorship. The resultant structures enable us to develop these large-scale and capital-intensive projects at a significantly faster pace. Numerous minor transactions were also completed to ready ourselves for our new mandate.d) Net present value of future net revenue using forecast prices and costs (millions) at December 31, 2010 Net present value of future net revenue before income taxes (discounted @) -----------------------------------------------Reserve Category (1) 0% 5% 10% 15% 20%----------------------------------------------------------------------------Proved Developed producing $ 12,873 $ 9,126 $ 7,202 $ 6,017 $ 5,206 Developed non-producing 448 333 261 214 182 Undeveloped 2,464 1,401 881 585 400---------------------------------------------------------------------------- Total proved $ 15,784 $ 10,860 $ 8,344 $ 6,817 $ 5,788Probable 7,266 3,848 2,427 1,693 1,260----------------------------------------------------------------------------Total proved plus probable $ 23,051 $ 14,708 $ 10,771 $ 8,510 $ 7,048----------------------------------------------------------------------------(1) Columns may not add due to rounding.Net present values take into account wellbore abandonment liabilities and are based on the price assumptions that are contained in the following table.

The future benefit of approximately $640 million raised from joint venture activities, in the form of carried capital, was not included in the Adjusted FD&A calculation, nor was this benefit included in FDC. Capital expenditures for 2010 have been reduced by $17 million related to joint venture carried capital (2009 - nil). We use Adjusted FD&A to assess the economic viability and the stage of development of our resource plays. F&D costs are calculated in accordance with NI 51-101, which include the change in FDC, on a proved and proved plus probable basis. For comparative purposes we also disclose F&D costs excluding FDC.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.

In 2010, during the ramp up to conversion, we focused on appraising the resource potential of our extensive portfolio of light-oil weighted assets and on positioning the company as the dominant operator in the development of conventional oil in western Canada.This appraisal work sets up a capital intensive development stage that we believe will deliver with it better capital efficiencies and improved project returns.Penn West ramped up drilling in the fourth quarter of 2010 on four major tight oil plays. The plays are performing as we had anticipated with production in line with our established production type-curves. Throughout the fourth quarter we continued to build operational capacity. We achieved a 2010 exit rate in-line with previous guidance at just over 167,000 boe per day despite the impact of approximately 1,900 boe per day of production lost due to pipeline apportionment.The 2011 capital program will increase our activity level on the Cardium and Carbonates light-oil projects. These longer lead-time, higher reserves projects complement our shallower, light-oil plays in the Colorado and at Waskada.We are now the most active driller in western Canada. We anticipate 2011 to be a year marked by ongoing resource appraisal and a move toward full scale project development as the year progresses. We are targeting five percent growth in 2011 via a capital program dominated by light-oil development. Cost reduction through efficiency and technology continues to be a priority in all project areas. We are also actively identifying those areas where both near-term and long-term strategic consolidation opportunities are present. Areas currently being assessed are both in active resource play areas as well as early-stage exploration plays.Our basket of large scale resource opportunities provided us the ability to execute on two significant joint venture agreements in 2010. These agreements, one partnership to develop bitumen resources in the Peace River oilsands block and a joint venture to develop shale gas assets in the Cordova Embayment of northeastern British Columbia, further evidence the size and potential of our portfolio. In the case of both transactions, partial cash consideration was paid upfront which was used to strengthen our balance sheet and provide ongoing financial flexibility to the Company. A carry on future capital associated with these joint ventures means that of a projected $1.85 billion in capital spending over the next 4-5 years, our partners will contribute approximately $1.6 billion. Appraisal work has begun on these assets and we believe the ultimate resource potential of these significant plays will provide attractive returns to Penn West shareholders.On converting the Trust to a conventional corporation, the Board of Directors, acting on management's recommendation, adopted a business model that will balance growth with income. We anticipate our initial quarterly dividend as a conventional corporation to be declared payable on April 15, 2011 to shareholders of record on March 31, 2011.Penn West is eagerly looking forward to increasing shareholder value based on a platform of growth and income.On behalf of the Board of Directors,William E. Andrew, Chief Executive OfficerMurray R. Nunns, President and Chief Operating OfficerCalgary, AlbertaFebruary 16, 2011OutlookThis outlook section is included to provide shareholders with information about our expectations as at February 16, 2011 for production and capital expenditures for 2011 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".Based on an average crude oil price of WTI US$80.00 per barrel and an average natural gas price of $4.70 per mcf, we expect our 2011 exploration and development capital program to be in the range of approximately $1.1-$1.2 billion. We are focusing our 2011 capital program on our suite of large-scale light-oil plays including the Cardium, the Colorado, the Carbonates and Waskada. Based on this level of capital expenditures, we continue to forecast 2011 average production to be approximately 172,000 to 177,000 boe per day.To date in the first quarter of 2011, we continue to experience production losses from Enbridge pipeline apportionments as well as issues at a partner operated gas facility in the Swan Hills area which resulted in the approximate loss of an additional 3,500 boe per day. We are optimistic that our partner operated gas facility in the Swan Hills area will return to full production in the near future. We do not anticipate a complete resolution to the current apportionment issues prior to the end of the first quarter. Penn West is maintaining its original guidance in the range of 172,000 - 177,000 boe per day as we are confident that we can overcome these production losses which were beyond our control.There have been no changes from our prior forecast for 2011 released on November 5, 2010, with our 2010 third quarter results and filed on SEDAR at www.sedar.com. Our actual 2010 exploration and development capital was slightly higher than our forecast of approximately $1.0 billion mainly due to our success at land sales and the advancement of our key light-oil properties which led to additional spending in late 2010.Non-GAAP Measures AdvisoryThe above information includes non-GAAP measures not defined under generally accepted accounting principles ("GAAP"), including funds flow, funds flow per unit-basic, netback, payout ratio and net debt. Non-GAAP measures do not have any standardized meaning prescribed by GAAP and therefore may not 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 dividends and planned capital programs. See "Calculation of Funds Flow" below. Netback is a per-unit-of-production measure of operating margin used in capital allocation decisions and to economically rank projects. Operating margin is calculated as revenue less royalties, operating costs and transportation and is used for similar purposes to netback. Payout ratio is calculated as distributions or dividends paid divided by funds flow. We use payout ratio to assess the adequacy of retained funds flow to finance capital programs. Net debt is calculated as the sum of long-term debt, convertible debentures and working capital (excluding risk management and future income taxes) and is used to assess our leverage levels and hence the continuing appropriateness of our dividend and capital investment levels.Oil and Gas Information AdvisoryBarrels of oil equivalent ("boe") may be misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet of natural gas to one barrel of crude oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.Forward- Looking StatementsThis press release contains forward-looking statements.

Barrels of oil equivalent ("boe") may be misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet of natural gas to one barrel of crude oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.Measures including funds flow, funds flow per unit-basic, funds flow per unit-diluted, netback, net debt, return on equity and return on capital included in this Management Commentary 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. 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 dividend and planned capital programs. See below for reconciliations of funds flow to its nearest measure prescribed by GAAP. Netback is a per-unit-of-production measure of operating margin used in capital allocation decisions and to economically rank projects. Operating margin is calculated as revenue less royalties, operating costs and transportation and is used for similar purposes to netback. Net debt is the sum of long-term debt, convertible debentures and working capital (excluding risk management and future income taxes) and is used to assess our leverage levels and hence the continuing appropriateness of our dividend and capital investment levels. Return on equity is the rate of return calculated by comparing net income to unitholders equity. Return on capital is calculated using net income and financing charges compared to unitholder equity and long-term debt and is used to assess how well Penn West utilizes the capital invested into the company.Calculation of Funds Flow Three months ended Year ended December 31 December 31 ----------------------------------------(millions, except per unit amounts) 2010 2009 2010 2009----------------------------------------------------------------------------Cash flow from operating activities $ 303 $ 438 $ 1,217 $ 1,401Increase (decrease) in non-cash working capital (13) (88) (85) 27Asset retirement expenditures 15 16 53 65----------------------------------------------------------------------------Funds flow $ 305 $ 366 $ 1,185 $ 1,493----------------------------------------------------------------------------Basic per unit $ 0.67 $ 0.87 $ 2.68 $ 3.62Diluted per unit $ 0.66 $ 0.86 $ 2.65 $ 3.60----------------------------------------------------------------------------Annual Financial Summary Year ended December 31 ---------------------------------------(millions, except per unit amounts) 2010 2009 2008----------------------------------------------------------------------------Gross revenues (1) $ 3,034 $ 3,203 $ 4,651Funds flow 1,185 1,493 2,537 Basic per unit 2.68 3.62 6.75 Diluted per unit 2.65 3.60 6.66Net income (loss) 226 (144) 1,221 Basic per unit 0.51 (0.35) 3.25 Diluted per unit 0.50 (0.35) 3.22Capital expenditures, net (2) 1,187 688 1,095Long-term debt at year-end 2,496 3,219 3,854Convertible debentures 255 273 296Distributions paid (3) 708 910 1,500Total assets $ 13,368 $ 13,876 $ 15,412----------------------------------------------------------------------------(1) Gross revenues include realized gains and losses on commodity contracts.(2) Excludes business combinations and net proceeds on property acquisitions and dispositions.(3) Includes distributions paid and reinvested in trust units under the distribution reinvestment plan.2010 Year-to-date Highlights- Production averaged 164,633 boe per day and was weighted 60 percent to liquids and 40 percent to natural gas.- Net debt was reduced by approximately $536 million during 2010.- Capital expenditures, net, for 2010 totalled $1,187 million including $102 million of strategic land acquisitions to further strengthen our position in key resource plays and excluding $17 million of joint venture carried capital. Net dispositions were $1,306 million in 2010 compared to $369 million in 2009.- Funds flow for 2010 was $1,185 million compared to $1,493 million in 2009. The decline was primarily due to lower realized risk management gains.- Net income was $226 million compared to a net loss of $144 million for 2009. The increase was primarily due to higher oil and natural gas revenues and lower unrealized risk management losses.- Netback was $25.07 per boe compared to $26.32 per boe in 2009.Fourth Quarter 2010 HighlightsKey financial and operational results for the fourth quarter of 2010 were as follows:- Production averaged 166,148 boe per day and was weighted 63 percent to liquids and 37 percent to natural gas.- Capital expenditures, net, totalled $400 million compared to $196 million in the fourth quarter of 2009. During the fourth quarter of 2010, we closed net property acquisitions of $69 million (2009 - $196 million net dispositions).- Funds flow in the quarter was $305 million compared to $366 million in the fourth quarter of 2009. The decline was primarily due to realized risk management losses.- Net loss was $21 million compared to a net loss of $12 million in the fourth quarter of 2009.- Netback was $25.34 per boe compared to $28.11 per boe in the fourth quarter of 2009. The decline was primarily due to realized risk management losses.- In January 2011, we completed the closing of a private placement of notes (the "2010 Q4 Notes") totalling approximately US$230 million.Quarterly Financial Summary(millions, except per unit and production amounts) (unaudited)Three Dec.

This led to financial assistance and fiscal easing measures in the U.S. and Europe in an effort to promote economic growth and job creation. In contrast, Asia and many of the world's developing economies have returned to growth levels similar to those experienced before the recent economic crisis prompting China, in particular, to begin fiscal tightening measures.In early 2011, political tension in some North African and Middle Eastern countries resulted in upward pressure on crude oil prices with WTI trading over US$90.00 and Brent trading over US$100.00. Protests and similar activities in these regions led to concerns regarding the possibility of disruptions of crude oil shipments through the Suez Canal and other routes important to future crude oil supply.Commodity MarketsGlobal demand growth for crude oil exceeded increases in non-OPEC supply over the past year. The high demand from Asia and the developing economies of the world reduced OPEC's spare capacity resulting in price levels which support capital investment in oil development. This is evidenced by a year-over-year doubling of active rigs targeting oil in the United States. Demand growth for energy in North America and Europe remains weaker than in Asia and the developing economies.Natural gas demand remained high in Asia over the past year resulting in premium prices in international markets compared to North America. North American natural gas markets continue to be oversupplied as lower prices have not led to a large enough reduction in drilling activity. Many producers continue to drill to retain their lease rights.Crude OilIn 2010, WTI crude oil prices averaged US$79.55 per barrel compared to US$61.93 per barrel in 2009. During the fourth quarter of 2010, crude oil prices averaged WTI US$85.18 per barrel, an increase from WTI US$76.21 per barrel in the third quarter of 2010 and WTI US$76.17 per barrel in the fourth quarter of 2009. Canadian producers experienced delays in the second half of 2010 delivering their production to market due to certain pipeline failures that occurred on the Enbridge system. Crude supply continues to be apportioned as Enbridge works to return its pipelines to full operation and reduce high inventory levels resulting from these service interruptions. As a result, it has been challenging for some producers to deliver their production to market and in some situations discounts on certain Canadian streams and shut-ins of certain production occurred. It is anticipated that these pipeline capacity issues will be resolved in the upcoming months.Our average liquids price before the impact of the realized portion of risk management for 2010 was $67.68 per barrel and for the fourth quarter of 2010 was $69.58 per barrel. Currently, we have risk management contracts of 35,000 barrels per day of our 2011 crude oil production at prices between US$80.06 per barrel and US$91.98 per barrel and 20,000 barrels per day of our forecasted 2012 crude oil production between US$84.25 per barrel and US$98.45 per barrel.Natural GasIn 2010, the AECO Monthly Index averaged $4.12 per mcf compared to $4.13 per mcf in 2009. During the fourth quarter of 2010, the AECO Monthly Index averaged $3.58 per mcf compared to $3.72 per mcf in the third quarter of 2010 and $4.23 per mcf in the fourth quarter of 2009. Natural gas prices remained weak throughout 2010 and drilling activity for shale gas, primarily in the U.S., continued notwithstanding the low prices. This drilling activity persisted for several reasons, most notably, producers drilling to retain leases, producers receiving enhanced value from the high liquids content of some shale gas plays and the infusion of joint venture capital from foreign partners. This led to production rates increasing year-over-year without a significant increase in demand resulting in inventory levels at or near record highs throughout most of 2010.Our corporate average natural gas price before the impact of the realized portion of risk management was $4.20 per mcf for 2010 and $3.79 per mcf for the fourth quarter of 2010. We currently have no natural gas risk management contracts for 2011 or beyond.Business StrategyOn January 1, 2011, we converted to an exploration and production ("E&P") company. Our transition to an E&P was seamless and moving forward we anticipate a level of return for our shareholders to include an element of both growth and yield.Over the past few years we have been building towards our corporate conversion and have executed on a number of strategies in advance of our conversion date. These strategies include a thorough evaluation of our resource plays, acquisition and divestiture activity in order to focus our asset base and create efficiencies, a build-up of our drilling locations inventory which is now over 8,000 including approximately 3,800 specific locations, the strengthening of our balance sheet through debt reduction, debt diversification and distribution reductions and the examination of our staff and technical expertise including exploration, to significantly increase and maintain our operating activities.Throughout 2010, we were active in strengthening our balance sheet and diversifying our debt portfolio along with accessing capital through the close of two strategic joint ventures. We completed transactions to this end including the following:- In January, we closed an asset swap (the "January 2010 asset swap") that increased our position in our Pembina and Dodsland light-oil plays in exchange for certain interests in the Leitchville area. We also received net cash consideration of $434 million, prior to closing adjustments.- In March, we completed a private placement of senior unsecured notes with an aggregate principal amount of approximately US$250 million and CAD $50 million.- In April, we closed the renewal of our unsecured, revolving syndicated bank facility for three years with an aggregate borrowing amount of $2.25 billion.- In June, we formed a joint venture partnership (the "Peace River Oil Partnership") to develop oil resources in the Peace River area in northern Alberta. As a result of the arrangement, we contributed assets for a 55 percent interest in the partnership and received $817 million which included cash of $312 million and a commitment of $505 million to fund our future capital and operating expenses. In addition, we closed a private placement issuing 23.5 million trust units for gross proceeds of $435 million ($424 million net).- In September, we formed a joint venture (the "Cordova Joint Venture") to develop our unconventional natural gas assets located in northeastern British Columbia. As a result of the arrangement, we sold a 50 percent interest in this property in exchange for approximately $250 million of cash and a commitment from our partner to fund $600 million of the first $800 million of capital expenditures.- In December, we closed the first tranche of a private placement of senior unsecured notes with an aggregate principal amount of US$95 million and CAD$60 million. In January 2011, we closed the second tranche of the private placement for US$75 million. The aggregate principal amount of both tranches is approximately US$170 million and CAD$60 million.In 2011 we plan to allocate 90 percent of our capital program to our significant inventory of light-oil projects. We will continuously evaluate the results of our 2011 capital program and assess areas where the rate of development may be increased.Performance IndicatorsOur management and Board of Directors monitor our performance based upon a number of qualitative and quantitative factors including:- Finding and development ("F&D") costs - We use these metrics to assess the economic viability and the development stage of our resource plays.- Base operations - This includes our production performance and execution of our operational, health, safety, environmental and regulatory programs.- Shareholder value measures - This includes key metrics such as funds flow per share and dividends or distributions per share.- Financial, business and strategic considerations - This includes the management of our asset base, balance sheet stewardship, execution of financial transactions and the overall goal of creating shareholder value (return on investment).Finding and Development costs Year ended December 31 ----------------------------------------- 3-Year 2010 2009 2008 average----------------------------------------------------------------------------Adjusted FD&A including future development costs ("FDC") (1) FD&A costs per boe - proved plus probable $ 18.12 $ 23.77 $ 23.38 $ 22.81 FD&A costs per boe - proved $ 16.64 $ 15.11 $ 30.78 $ 26.93Excluding FDC (2) F&D costs per boe - proved plus probable $ 18.90 $ 13.75 $ 18.94 $ 17.40 F&D costs per boe - proved $ 21.50 $ 16.10 $ 27.17 $ 21.49Including FDC (3) F&D costs per boe - proved plus probable $ 26.73 $ 16.12 $ 24.57 $ 22.90 F&D costs per boe - proved $ 28.01 $ 16.19 $ 31.94 $ 25.51----------------------------------------------------------------------------(1) The calculation of FD&A includes the change in FDC, excluding the effect of economic revisions related to downward revisions of natural gas prices and land acquisition costs.(2) The calculation of F&D excludes the change in FDC and excludes the effects of acquisitions and dispositions.(3) The calculation of F&D includes the change in FDC and excludes the effects of acquisitions and dispositions.Our capital program increased during 2010 as we transitioned to an E&P company. We added approximately 72 million boe of proved plus probable reserves (excluding acquisitions and dispositions) as a result of our successful drilling program focused on our light-oil projects.The future benefit of approximately $640 million raised from joint venture activities, in the form of carried capital, was not included in the Adjusted FD&A calculation, nor was this benefit included in FDC. Capital expenditures for 2010 have been reduced by $17 million related to joint venture carried capital (2009 - nil). We use Adjusted FD&A to assess the economic viability and the stage of development of our resource plays. F&D costs are calculated in accordance with NI 51-101, which include the change in FDC, on a proved and proved plus probable basis. For comparative purposes we also disclose F&D costs excluding FDC.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.Base operationsThroughout 2010, our drilling results were generally consistent with our expectations as we increased our capital plan in anticipation of our conversion to an E&P company and due to our successful results at our light-oil resource plays. Weather issues in the summer and winter months resulted in interruptions in tying in wells and led to production delays. During the year, we closed two strategic joint venture arrangements, the Peace River Oil Partnership and Cordova Joint Venture, which provide us with a significant capital commitment from our partners and allow us to assess the resource potential and move into full-scale development in a shorter time-frame than we previously anticipated.Shareholder Value Measures Year ended December 31 --------------------------------------- 2010 2009 2008----------------------------------------------------------------------------Funds flow per unit $ 2.68 $ 3.62 $ 6.75Distributions paid per unit $ 1.62 $ 2.23 $ 4.08Ratio of year-end total long-term debt to annual funds flow 2.1:1 2.2:1 1.5:1----------------------------------------------------------------------------To implement our corporate strategy of providing shareholders with a return including both growth and yield in the near term the distribution level was decreased to $0.09 per unit per month effective with the September 2010 distribution paid in October 2010. These funds will be used to expand our capital program.The total long-term debt to annual funds flow ratio decreased in 2010 due to a decline in our long-term debt balance. This was partially offset by a reduction in annual funds flow due to lower production volumes resulting from net dispositions.Financial, business and strategic considerations Year ended December 31 --------------------------------------- 2010 2009 2008----------------------------------------------------------------------------Return on capital (1) 3% - 15%Return on equity (2) 3% (2)% 19%Total assets (millions) $ 13,368 $ 13,876 $ 15,412----------------------------------------------------------------------------(1) Net income before financing charges divided by average unitholders' equity and average total debt.(2) Net income divided by average unitholders' equity.The return on capital and return on equity ratios in 2010 increased primarily due to higher net income in 2010 and a reduction in our total debt. During 2010, we significantly reduced the outstanding balance on our syndicated bank facility by executing the January 2010 asset swap, the Peace River Oil Partnership transaction, the Cordova Joint Venture, an equity offering completed in June 2010 to a private investor and by the issuance of senior, unsecured notes.

Our focus in 2010 was continuing the development of our key light-oil plays which led to higher light-oil production than the prior year. During 2010, we experienced some unplanned interruptions due to poor weather which resulted in delays in tying in new wells and therefore delays in production coming on-stream. We drilled 319 net wells in 2010 primarily using horizontal multi-stage fracture technology, compared to 94 net wells in 2009.Production increased to 166,148 boe per day in the fourth quarter of 2010 from 164,087 boe per day in the third quarter of 2010. Our light-oil production volumes increased due to our concentrated capital program on our key light-oil resource plays. During the fourth quarter of 2010 extremely cold weather throughout western Canada led to some unanticipated interruptions resulting in production delays. We drilled 116 net wells during the fourth quarter primarily throughout our light-oil plays compared to 25 net wells in 2009.The decrease from the comparable periods in 2009 was mainly due to property dispositions including the Lloydminster property disposition completed in November 2009 of approximately 6,000 boe per day, predominantly of heavy oil, and the January 2010 asset swap of approximately 2,800 boe per day.When economic to do so, we strive to maintain a strategic mix of liquids and natural gas production in order to reduce exposure to price volatility that can affect a single commodity. In the fourth quarter of 2010, crude oil and NGL production averaged 105,296 barrels per day (63 percent of production) and natural gas production averaged 365 mmcf per day (37 percent of production).Average Sales Prices Three months ended Year ended December 31 December 31---------------------------------------------------------------------------- % % 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Light oil and NGL (per bbl) $ 71.05 $ 69.49 2 $ 69.29 $ 59.07 17Risk management gain (loss) (per bbl) (1) (4.12) 1.55 (100) (2.72) 8.19 (100)----------------------------------------------------------------------------Light oil and NGL net (per bbl) 66.93 71.04 (6) 66.57 67.26 (1)----------------------------------------------------------------------------Heavy oil (per bbl) 61.87 62.97 (2) 60.55 53.75 13----------------------------------------------------------------------------Natural gas (per mcf) 3.79 4.39 (14) 4.20 4.13 2Risk management gain (per mcf) (1) 0.31 0.49 (37) 0.42 0.69 (39)----------------------------------------------------------------------------Natural gas net (per mcf) 4.10 4.88 (16) 4.62 4.82 (4)----------------------------------------------------------------------------Weighted average (per boe) 52.43 51.19 2 50.74 44.11 15Risk management gain (loss) (per boe) (1) (1.51) 1.89 (100) (0.34) 5.32 (100)----------------------------------------------------------------------------Weighted average net (per boe) $ 50.92 $ 53.08 (4) $ 50.40 $ 49.43 2----------------------------------------------------------------------------(1) Gross revenues include realized gains and losses on commodity contracts.Netbacks Three months ended Year ended December 31 December 31 ---------------------------------------------------------- % % 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Light oil and NGL (1)Production (bbls/day) 88,447 77,627 14 80,706 78,011 3 Operating netback ($/bbl): Sales price $ 71.05 $ 69.49 2 $ 69.29 $ 59.07 17 Risk management gain (loss) (2) (4.12) 1.55 (100) (2.72) 8.19 (100) Royalties (13.79) (13.89) (1) (13.73) (10.78) 27 Operating costs (18.83) (19.74) (5) (19.83) (19.93) (1)---------------------------------------------------------------------------- Netback $ 34.31 $ 37.41 (8) $ 33.01 $ 36.55 (10)----------------------------------------------------------------------------Conventional heavy oilProduction (bbls/day) 16,849 24,009 (30) 18,260 25,962 (30) Operating netback ($/bbl): Sales price $ 61.87 $ 62.97 (2) $ 60.55 $ 53.75 13 Royalties (8.61) (9.52) (10) (8.73) (7.26) 20 Operating costs (17.28) (15.37) 12 (17.14) (15.54) 10 Transportation (0.11) (0.07) 57 (0.09) (0.06) 50---------------------------------------------------------------------------- Netback $ 35.87 $ 38.01 (6) $ 34.59 $ 30.89 12----------------------------------------------------------------------------Total liquidsProduction (bbls/day) 105,296 101,636 4 98,966 103,973 (5) Operating netback ($/bbl): Sales price $ 69.58 $ 67.95 2 $ 67.68 $ 57.74 17 Risk management gain (loss) (2) (3.46) 1.18 (100) (2.22) 6.14 (100) Royalties (12.96) (12.86) 1 (12.81) (9.90) 29 Operating costs (18.58) (18.71) (1) (19.33) (18.83) 3 Transportation (0.02) (0.02) - (0.02) (0.01) 100---------------------------------------------------------------------------- Netback $ 34.56 $ 37.54 (8) $ 33.30 $ 35.14 (5)----------------------------------------------------------------------------Natural gas Production (mmcf/day) 365 411 (11) 394 440 (10) Operating netback ($/mcf): Sales price $ 3.79 $ 4.39 (14) $ 4.20 $ 4.13 2 Risk management gain (2) 0.31 0.49 (37) 0.42 0.69 (39) Royalties (0.42) (0.69) (39) (0.58) (0.75) (23) Operating costs (1.88) (1.63) 15 (1.71) (1.57) 9 Transportation (0.23) (0.21) 10 (0.22) (0.21) 5---------------------------------------------------------------------------- Netback $ 1.57 $ 2.35 (33) $ 2.11 $ 2.29 (8)----------------------------------------------------------------------------Combined totalsProduction (boe/day) 166,148 170,164 (2) 164,633 177,221 (7) Operating netback ($/boe): Sales price $ 52.43 $ 51.19 2 $ 50.74 $ 44.11 15 Risk management gain (loss) (2) (1.51) 1.89 (100) (0.34) 5.32 (100) Royalties (9.14) (9.35) (2) (9.07) (7.66) 18 Operating costs (15.92) (15.10) 5 (15.71) (14.93) 5 Transportation (0.52) (0.52) - (0.55) (0.52) 6---------------------------------------------------------------------------- Netback $ 25.34 $ 28.11 (10) $ 25.07 $ 26.32 (5)----------------------------------------------------------------------------(1) Excluded from the netback calculation is $5 million of realized risk management gains related to our foreign exchange contracts which swap US dollar revenue at a fixed Canadian dollar rate.

Light oil and NGL production increased, notwithstanding the January 2010 asset swap, as we focused our 2010 capital program on light-oil resource plays. For 2010, heavy oil production was 30 percent lower and natural gas production was 10 percent lower than 2009.Reconciliation of decrease in Production Revenues(millions)----------------------------------------------------------------------------Gross revenues - January 1 - December 31, 2009 $ 3,203Increase in light oil and NGL production 66Decrease in light oil and NGL prices (including realized risk management) (21)Decrease in heavy oil production (151)Increase in heavy oil prices 47Decrease in natural gas production (80)Decrease in natural gas prices (including realized risk management) (30)----------------------------------------------------------------------------Gross revenues - January 1 - December 31, 2010 $ 3,034----------------------------------------------------------------------------Royalties Three months ended Year ended December 31 December 31 ----------------------------------------------------- % % 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Royalties (millions) $ 139 $ 146 (5) $ 545 $ 495 10Average royalty rate (1) 17% 18% (1) 18% 17% 1$/boe $ 9.14 $ 9.35 (2) $ 9.07 $ 7.66 18----------------------------------------------------------------------------(1) Excludes effects of risk management activities.In 2010, royalty rates and per boe amounts increased as a result of higher crude oil prices.

In 2010, acquisition and divestiture activity also contributed to an increase in the operating costs per boe.Operating costs for 2010 include a realized loss on electricity contracts of $14 million (2009 - $16 million).We have contracts in place that fix the price on approximately 90 percent of our electricity consumption for 2011 at US$63.16 per MWH.FinancingPenn West Petroleum Ltd. (the "Company") has a three-year, unsecured, revolving syndicated bank facility with an aggregate borrowing limit of $2.25 billion. The facility is extendible and expires on April 30, 2013. 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, 2010, approximately $0.8 billion was drawn under this facility.As at December 31, 2010, the Company had $1.7 billion of senior unsecured notes outstanding as follows: Weighted Average average Amount interest remaining Issue date (millions) Term rate term----------------------------------------------------------------------------2007 Notes May 31, 2007 US$475 8-15 years 5.80 percent 6.5 years US$480,2008 Notes May 29, 2008 CAD$30 8-12 years 6.25 percent 7.0 years Pounds Sterling 6.95 percentUK Notes July 31, 2008 57 10 years (1) 7.6 years US$154, Pounds Sterling May 5, 2009 20, EUR 10, 8.85 percent2009 Notes CAD$5 5-10 years (2) 6.0 years US$250,2010 Q1 March 16, 2010 CAD$50 5-15 years 5.47 percent 7.8 yearsNotes2010 Q4 December 2, 2010 US$95, 5-15 years 4.96 percent 9.8 yearsNotes (3) CAD$60----------------------------------------------------------------------------(1) These notes bear interest at 7.78 percent in Pounds Sterling, however, contracts were entered to fix the interest rate at 6.95 percent in Canadian dollars and to fix the exchange rate on the repayment.(2) The Company entered into contracts to fix the interest rate on the Pounds Sterling and Euro tranches, initially at 9.49 percent and 9.52 percent, to 9.15 percent and 9.22 percent, respectively. (3) An additional US$75 million of proceeds were received in January 2011 which completed the private placement. On March 16, 2010, the Company closed the private placement of the 2010 Q1 Notes with an aggregate principal amount of approximately US$250 million and CAD$50 million. The 2010 Q1 Notes have a weighted average term of 8.6 years and bear a weighted average fixed interest rate of approximately 5.47 percent. The Company used the proceeds of the issue to repay advances on its syndicated bank facility.In January 2011, the Company completed a closing of a private placement, the 2010 Q4 Notes, with an aggregate principal amount of approximately US$230 million. The 2010 Q4 Notes have a weighted average term of 10.8 years and bear a weighted average fixed interest rate of approximately 5.00 percent. The Company used the proceeds from the issue received on that date to repay advances on its syndicated bank facility.At December 31, 2010, the Company had the following interest rate swapsoutstanding: Nominal amount Fixed rateEffective date Termination date Initial term (millions) (percent)----------------------------------------------------------------------------December 2008 December 2011 3 years $ 500 1.61January 2009 January 2014 5 years $ 600 2.71June 2010 January 2014 3.5 years $ 50 1.94----------------------------------------------------------------------------The interest rates on any non-hedged portion of the Company's bank debt are subject to fluctuations in short-term money market rates as advances on the bank facility are generally made under short-term instruments. As at December 31, 2010, none (2009 - 14 percent) of our long-term debt instruments were exposed to changes in short-term interest rates. On December 31, 2010, our fixed interest rate debt (including the effects of interest rate swaps) had a weighted average rate of approximately 5.70 percent (2009 - 4.57 percent).Financing charges for both the fourth quarter and 2010 are higher year-over-year due to a higher percentage of our debt capital being held in senior unsecured notes compared to the prior period as well as the increased cost of borrowing with the new bank facility. The Company's senior unsecured notes contain higher interest rates than the syndicated bank facilities held in short-term money market instruments. Notwithstanding the current interest rate differentials, we believe the long-term and fixed interest rates inherent in the senior notes is favourable for a portion of our debt capital structure.Realized gains and losses on the interest rate swaps are recorded as financing costs. For the fourth quarter of 2010 an expense of $4 million (2009 - $8 million) and for 2010 an expense of $21 million (2009 - $21 million) was recognized in financing expense to reflect that the floating interest rate was lower than the fixed interest rate transacted under our financial instruments.Unit-Based CompensationUnit-based compensation expense is related to our Trust Unit Rights Incentive Plan ("TURIP") and our Long-Term Retention and Incentive Plan ("LTRIP"). The LTRIP was implemented in the first quarter of 2010. Compensation expense related to the TURIP is based on the fair value of trust unit rights issued, determined using a Binomial Lattice option-pricing model. The fair value of TURIP rights issued is amortized over the remaining vesting periods on a straight-line basis and is allocated to operating and general and administrative expense as applicable. The intrinsic cost of the LTRIP is charged to income based on our unit price at the end of each reporting period plus accumulated dividends or distributions multiplied by the number of LTRIP awards outstanding. The LTRIP obligation is accrued over the vesting period as service is completed by employees and is allocated to operating and general and administrative expense as applicable based on a graded vesting schedule. Subsequent increases and decreases in the underlying unit price will result in increases and decreases, respectively, to the underlying LTRIP obligation until settlement.

The increase in the cost per boe in 2010 was due to higher costs and lower production volumes during the year from property dispositions.Depletion, Depreciation and Accretion ("DD&A") Three months ended Year ended December 31 December 31 -------------------------------------------------------(millions, except % % per boe amounts) 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Depletion of oil and natural gas assets $ 331 $ 357 (7) $ 1,293 $ 1,514 (15)Accretion of asset retirement obligations 14 10 40 45 42 7----------------------------------------------------------------------------Total DD&A $ 345 $ 367 (6) $ 1,338 $ 1,556 (14)----------------------------------------------------------------------------DD&A expense per boe $ 22.56 $ 23.41 (4) $ 22.27 $ 24.04 (7)----------------------------------------------------------------------------DD&A for 2010 decreased compared to the prior year as a result of the contribution of assets into the Peace River Oil Partnership and Cordova Joint Venture and lower production volumes due to property dispositions.Taxes Three months ended Year ended December 31 December 31 ------------------------------------------------------- % %(millions) 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Future income tax recovery $ (50) $ (82) (39) $ (319) $ (378) (16)----------------------------------------------------------------------------The 2010 recovery included $177 million related to corporate restructuring. The comparative figure in 2009 included a $168 million recovery related to unrealized risk management losses and a $65 million recovery related to income tax legislation enacted by the Government of Canada which reduced the provincial component of the SIFT tax rate from 13 percent to 10 percent.Under the income trust structure, which we operated in 2010, the operating entities make interest and royalty payments to the Trust, which transfers taxable income to the Trust level, eliminating income subject to corporate income taxes in the operating entities. The Trust eliminated its taxable income, in part, by deducting distributions paid to its unitholders. Under the Specified Investment Flow-Through ("SIFT") legislation, which was enacted in June 2007 and was effective on January 1, 2011, distributions are no longer tax deductible by trusts.On January 1, 2011, we converted into a publicly-traded corporation. In 2011 and beyond, we are now subject to current and future taxes at normal Canadian corporate rates. As the currently legislated SIFT rates are comparable to corporate tax rates, we do not anticipate our conversion to an E&P company to result in a significant adjustment to our existing future tax liability under Canadian GAAP.We currently have a significant tax pool base. Based on current commodity prices and capital spending plans, we forecast we could use these pools to shelter our taxable income for an extended period after 2010.Tax Pools As at December 31 -------------------------(millions) 2010 2009----------------------------------------------------------------------------Undepreciated capital cost (UCC) $ 1,122 $ 1,379Canadian oil and gas property expense(COGPE) 1,564 1,912Canadian development expense (CDE) 1,494 1,141Canadian exploration expense (CEE) 305 280Non-capital losses 2,481 2,139Other 31 16----------------------------------------------------------------------------Total $ 6,997 $ 6,867----------------------------------------------------------------------------Tax pool amounts exclude income deferred in operating partnerships of $920 million in 2010 (2009 - $931 million).Foreign Exchange Three months ended Year ended December 31 December 31 ------------------------------------------------------- % %(millions) 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Unrealized foreign exchange gain $ (55) $ (25) 100 $ (82) $ (186) (56)----------------------------------------------------------------------------We record unrealized foreign exchange gains or losses to translate the U.S., UK and Euro notes and the related accrued interest to Canadian dollars using the exchange rates in effect on the balance sheet date. The $82 million gain during 2010 was primarily due to the strengthening of the Canadian dollar relative to the US dollar.Funds Flow and Net Income (Loss) Three months ended Year ended December 31 December 31 ------------------------------------------------------- % % 2010 2009 change 2010 2009 change----------------------------------------------------------------------------Funds flow (1) (millions) $ 305 $ 366 (17) $ 1,185 $ 1,493 (21) Basic per unit 0.67 0.87 (23) 2.68 3.62 (26) Diluted per unit 0.66 0.86 (23) 2.65 3.60 (26)Net income (loss) (millions) (21) (12) (75) 226 (144) 100 Basic per unit (0.05) (0.03) (67) 0.51 (0.35) 100 Diluted per unit $ (0.05) $ (0.03) (67) $ 0.50 $ (0.35) 100----------------------------------------------------------------------------(1) Funds flow is a non-GAAP measure. See "Calculation of Funds Flow".Funds flow in 2010 was lower than 2009 primarily as a result of property dispositions and lower realized risk management gains. The 2009 comparative figure also includes the monetization of foreign exchange contracts for a gain of $75 million.Net income for 2010 was higher than 2009 primarily due to higher oil and natural gas revenues and lower unrealized risk management losses. For the fourth quarter of 2010, the net loss was mainly due to lower realized risk management gains compared to the fourth quarter of 2009.Capital Expenditures Three months ended Year ended December 31 December 31 ----------------------------------------(millions) 2010 2009 2010 2009----------------------------------------------------------------------------Land acquisition and retention $ 10 $ 3 $ 102 $ 19Drilling and completions 263 89 800 286Facilities and well equipping 140 86 281 336Geological and geophysical - 3 10 9Corporate 4 15 11 38----------------------------------------------------------------------------Capital expenditures 417 196 1,204 688Joint venture, carried capital (17) - (17) -----------------------------------------------------------------------------Capital expenditures, net $ 400 $ 196 $ 1,187 $ 688----------------------------------------------------------------------------Total expenditures Three months ended Year ended December 31 December 31 ----------------------------------------(millions) 2010 2009 2010 2009----------------------------------------------------------------------------Capital expenditures $ 417 $ 196 $ 1,204 $ 688Property acquisitions (dispositions), net 69 (196) (1,306) (369)Business combinations 139 - 139 116----------------------------------------------------------------------------Total expenditures $ 625 $ - $ 37 $ 435----------------------------------------------------------------------------During 2010, we increased our capital spending compared to 2009 in preparation for our conversion to an E&P company and due to early success at our light-oil resource plays. This resulted in an increase in drilling and completions expenditures year-over-year. Our focus throughout 2010 was to continue to advance development at our key light-oil plays located in the Cardium, the Colorado, the Carbonates and Waskada.During 2010, we drilled 319 net wells (2009 - 94) resulting in 245 net oil wells, 38 net natural gas wells and 34 stratigraphic and service wells with a success rate of 99 percent (2009 - 98 percent). For the fourth quarter of 2010, we drilled 116 net wells (2009 - 25) which included 93 net oil wells, 13 net natural gas wells and 10 net stratigraphic and service wells. Throughout 2010, we utilized horizontal multi-stage fracture technology on most of our wells drilled, excluding stratigraphic and service wells.For 2010, $89 million was capitalized (2009 - $26 million disposed) for additions to asset retirement obligations from our capital program and property acquisitions, net of property dispositions.January 2010 asset swapIn the first quarter of 2010, we closed an Asset Exchange Agreement increasing our position in our light-oil resource plays at Pembina and Dodsland with total production of approximately 560 boe per day in exchange for certain interests in the Leitchville area with total production of approximately 3,500 boe per day. Additionally, we received net cash proceeds of approximately $434 million which was applied to our bank facility.Peace River Oil PartnershipIn the second quarter of 2010, we closed the transaction creating the Peace River Oil Partnership to develop oil resources in the Peace River area of northern Alberta. We contributed assets valued at $1.8 billion, retaining a 55 percent interest in the partnership and received approximately $817 million which included $312 million cash paid upon closing and $505 million committed to us to fund our share of future capital and operating expenses for the Peace River Oil Partnership. As a result, on approximately the first $1.0 billion of capital and operating costs incurred by the partnership, we will contribute approximately $56 million while maintaining our 55 percent interest in the partnership. In addition, we closed a private placement issuing approximately 23.5 million trust units to our partner for gross proceeds of $435 million ($424 million net).Cordova Joint VentureIn the third quarter of 2010, we closed a joint venture agreement with a subsidiary of Mitsubishi Corporation ("Mitsubishi") to develop our shale gas assets in the Cordova Embayment and certain conventional gas assets at our Wildboy property in northeastern British Columbia. As a result of the arrangement, we sold a 50 percent interest in these assets to Mitsubishi in exchange for approximately $450 million consisting of $250 million of cash and approximately $205 million of future commitments. Mitsubishi will fund $600 million of the first $800 million of capital expenditures in this joint venture and we will continue to serve as the operator of the assets.Sifton Energy Inc. ("Sifton") acquisitionOn December 22, 2010, we closed the acquisition of Sifton, a private oil and gas exploration company with assets primarily located in the Cardium light-oil resource play in Central Alberta. The total acquisition cost was approximately $108 million, which included the assumption of approximately $23 million of debt and working capital.Goodwill(millions) December 31, 2010 December 31, 2009----------------------------------------------------------------------------Balance, beginning and end of period $ 2,020 $ 2,020----------------------------------------------------------------------------We recorded goodwill on our acquisitions of Petrofund Energy Trust, Canetic Resources Trust and Vault Energy Trust. We determined there was no goodwill impairment at December 31, 2010.Business RisksWe are exposed to normal market risks inherent in the oil and natural gas business, including, but not limited to, commodity price risk, foreign currency risk, credit risk, interest rate risk, liquidity risk and environmental and climate change risk. We seek to mitigate these risks through various business processes and management controls and from time to time by using financial instruments.For a summary of outstanding financial instruments, please refer to "Financial Instruments" later in this Management Commentary.Commodity Price RiskCommodity price fluctuations are among our most significant exposures. Crude oil prices are influenced by worldwide factors such as OPEC actions, world supply and demand fundamentals, and geopolitical events. Natural gas prices are influenced by the price of alternative fuel sources such as oil or coal and by North American natural gas supply and demand fundamentals including the levels of industrial activity, weather, storage levels and liquefied natural gas activity. 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.Foreign Currency Rate RiskPrices received for crude oil are referenced to or denominated directly in US dollars, thus our realized oil prices are impacted by Canadian dollar to US dollar exchange rates. A portion of our debt capital is denominated in US dollars, thus the principal and interest payments in Canadian dollars are also impacted by exchange rates. When we consider it appropriate, we may use financial instruments to fix or collar future exchange rates to fix the Canadian dollar equivalent of crude oil revenues or to fix US denominated long-term debt principal repayments. At December 31, 2010, we had the following foreign currency forward contracts outstanding: Nominal AmountInitial Term (millions) Termination date Exchange rate----------------------------------------------------------------------------19-month term Sell US$378 December 2011 1.06085 CAD/USD8-year term Buy US$80 May 2015 1.01027 CAD/USD10-year term Buy US$80 May 2017 1.00016 CAD/USD12-year term Buy US$70 May 2019 0.99124 CAD/USD15-year term Buy US$20 May 2022 0.98740 CAD/USD----------------------------------------------------------------------------At December 31, 2010, we had US dollar denominated debt with a face value of US$1.2 billion (2009 - US$0.9 billion) on which the repayment of the principal amount in Canadian dollars is not fixed.Credit RiskCredit 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 generally subject to normal industry credit risk, which includes the right to recover unpaid receivables by receiving the partner's share of production when we are the operator. For oil and natural gas sales and financial derivatives, we follow a counterparty risk procedure whereby each counterparty is reviewed on a regular basis for the purpose of assigning a credit limit and may be requested to provide security if determined to be prudent. For financial derivatives, we normally transact with counterparties who are members of our banking syndicate or other counterparties that have investment grade bond ratings. We monitor credit events related to all counterparties and reassess credit exposures on a regular basis. As necessary, provisions for potential credit related losses are recognized.As at December 31, 2010, the maximum exposure to credit risk was $386 million (2009 - $371 million) being the carrying value of the accounts receivable.Interest Rate RiskWe 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 remain at lower levels 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. As at December 31, 2010, none of our long-term debt instruments were exposed to changes in short-term interest rates (2009 - 14 percent).As at December 31, 2010, we had a total of $1.7 billion of fixed interest rate debt instruments and $0.3 billion of convertible debentures outstanding. On the fixed interest rate debt the average remaining term was 7.2 years (2009 - 7.7 years) with an average interest rate of 5.70 percent (2009 - 4.57 percent), including the effects of interest rate swaps. For further details on these instruments, refer to the "Financing" and "Convertible Debentures" sections in this Management Commentary.Liquidity RiskLiquidity risk is the risk that we will be unable to meet our financial liabilities as they come due. Management utilizes short and long-term financial and capital forecasting programs 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 cash flow from operating activities.The following table outlines estimated future contractual obligations for non-derivative financial liabilities as at December 31, 2010:(millions) 2011 2012 2013 2014 2015 Thereafter----------------------------------------------------------------------------Bank debt $ - $ - $ 773 $ - $ - $ -Senior unsecured notes - - 5 60 251 1,407Convertible debentures 255 - - - - -Accounts payable 743 - - - - -Distributions payable 41 - - - - -----------------------------------------------------------------------------Total $ 1,039 $ - $ 778 $ 60 $ 251 $ 1,407----------------------------------------------------------------------------Environmental and Climate Change RiskThe 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, site restoration requirements and 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 and under certain assumptions, become material.We are dedicated to reducing the environmental impact from our operations through our environmental programs which include resource conservation, stakeholder communication, CO2 sequestration, water management and site abandonment/reclamation. We continuously monitor our operations to minimize the environmental impact from our operations, allocate sufficient capital to reclamation and other activities and are committed to mitigating the impact in the areas in which we operate.Liquidity and Capital ResourcesCapitalization As at December 31 ------------------------------------------ 2010 2009----------------------------------------------------------------------------(millions) % %----------------------------------------------------------------------------Trust units issued, at market (1) $ 10,959 78 $ 7,821 69Bank loans and long-term notes 2,496 18 3,219 28Convertible debentures 255 2 273 2Working capital deficiency (2) 311 2 106 1----------------------------------------------------------------------------Total enterprise value $ 14,021 100 $ 11,419 100----------------------------------------------------------------------------(1) The unit price at December 31, 2010 was $23.84 (2009 - $18.55).(2) Excludes the current portion of risk management, future income taxes and convertible debentures.For 2010, we paid total distributions, including those funded by the distribution reinvestment plan, of $708 million (2009 - $910 million).The decline in long-term debt in 2010 was mainly due to repayments made on our syndicated bank facility using proceeds received from the January 2010 asset swap, cash received upon closing of the Peace River Oil Partnership transaction and the Cordova Joint Venture and an equity offering completed in June 2010 to a private investor. On April 30, 2010, the Company closed the renewal of its unsecured, revolving, syndicated bank facilities with an aggregate borrowing limit of $2.25 billion and as of December 31, 2010 had approximately $1.5 billion of unused credit capacity available. For further details on these debt instruments, please refer to the "Financing" and "Convertible Debentures" sections of this Management Commentary.We actively manage our debt portfolio and consider opportunities to reduce or diversify our debt structure. We have an active risk management program to limit our exposure to certain risks and maintain close relationships with our lenders and agents to monitor credit market developments. These actions aim to increase the likelihood of maintaining our financial flexibility to capture opportunities available in the markets in addition to the continuation of our capital and dividend programs and the longer-term execution of our business strategies.The Company has a number of covenants related to its syndicated bank facility and senior, unsecured notes. On December 31, 2010, the Company was in compliance with all of these financial covenants which comprise the following: Limit December 31, 2010----------------------------------------------------------------------------Senior debt to EBITDA Less than 3:1 1.84Total debt to EBITDA Less than 4:1 1.86Senior debt to capitalization Less than 50 percent 23%Total debt to capitalization (1) Less than 55 percent 23-25%----------------------------------------------------------------------------(1) The definitions of Total debt differ slightly among the agreements in relation to convertible debentures.As at December 31, 2010, all senior, unsecured notes, except for the 2007 Notes, contain change of control provisions whereby if a change of control occurs, the Company may be required to offer to prepay the notes, which the holders have the right to refuse. Our conversion to a corporation did not trigger a change in control under the note agreements. As of January 1, 2011, upon completion of our corporate conversion, all note agreements now have change of control provisions.As an income trust, we paid distributions in cash as the Trust was required to make distributions to unitholders in amounts at least equal to its taxable income; however, the amount of taxable income allocated to the Trust from the operating entities was subject to management's discretion. Beginning on January 1, 2011, under our new corporate structure, the amount of future cash dividends may vary depending on a variety of factors and conditions which can include fluctuations in commodity markets, production levels and capital expenditure requirements. Our dividend policies are subject to change based on these and other factors and is subject to the discretion of our Board of Directors.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 obligations.Convertible DebenturesDuring 2010, $18 million of convertible debentures matured and were settled in units (2009 - $7 million), none were redeemed and settled in units (2009 - $12 million) and none were redeemed and settled in cash (2009 - $4 million). There was no change in the convertible debenture balances in the fourth quarter of 2010 or in the comparable period in 2009.On January 26, 2011, due to our conversion to a corporation and in accordance with the debenture indentures, we announced our offer to repurchase all of our outstanding convertible debentures. Debenture holders are entitled to receive cash consideration in the amount of the offer price equal to 101 percent of the outstanding principal amounts plus accrued interest with the offer closing on March 3, 2011. At the time of the announcement we had approximately $255 million of convertible debentures outstanding.At December 31, 2010, the balance of our unsecured, subordinated convertible debentures outstanding was as follows: Conversion RedemptionDescription of Outstanding Maturity price prices (per security (millions) date (per unit) $1,000 face value)----------------------------------------------------------------------------PWT.DB.E $1,025 May 31, 20107.2% Convertible $ 26 May 31, 2011 $75.00 to maturityPWT.DB.F6.5% Convertible $1,025 Dec. 31, 2010 extendible 229 Dec. 31, 2011 $51.55 to maturity----------------------------------------------------------------------------Total $ 255----------------------------------------------------------------------------Financial InstrumentsWe had the following financial instruments outstanding as at December 31, 2010.

If we are not successful in renewing or replacing the facility, we could be required to repay all amounts then outstanding on the facility or enter other loans including term bank loans. In addition, we have an aggregate of $1.7 billion in senior notes maturing between 2014 and 2025. We continuously monitor our credit metrics and maintain positive working relationships with our lenders, investors and agents.Convertible debentures with an aggregate principal amount of $255 million were outstanding on December 31, 2010 (2009 - $273 million). A significant portion of the interest payable on convertible debentures may, at our option, be settled by the issuance of shares. As at February 16, 2011, convertible debentures with an aggregate principal amount of $255 million were outstanding. For a schedule of convertible debenture maturities, please refer to the "Convertible Debentures" section of this Management Commentary.Equity Instruments----------------------------------------------------------------------------Trust units issued: Trust units as at December 31, 2010 459,682,249 Trust units cancelled on January 1, 2011 (459,682,249)----------------------------------------------------------------------------As at January 1, 2011 -----------------------------------------------------------------------------Common shares issued: Issuance of common shares on January 1, 2011 459,682,249 Issued on exercise of options 1,211,795 Issued on exercise of common share rights 225,478 Issued on settlement of restricted rights 3,433 Issued pursuant to dividend reinvestment plan 299,097---------------------------------------------------------------------------- As at February 16, 2011 461,422,052----------------------------------------------------------------------------Trust unit rights outstanding: Trust unit rights outstanding as at December 31, 2010 31,365,478 Trust unit rights cancelled on January 1, 2011 (31,365,478)---------------------------------------------------------------------------- As at January 1, 2011 -----------------------------------------------------------------------------Options outstanding: Issuance on January 1, 2011 27,586,712 Granted 78,130 Exercised (1,211,795) Forfeited (152,083)---------------------------------------------------------------------------- As at February 16, 2011 26,300,964----------------------------------------------------------------------------Common share rights outstanding: Issuance on January 1, 2011 3,778,766 Exercised (225,478) Forfeited (43,701)---------------------------------------------------------------------------- As at February 16, 2011 3,509,587----------------------------------------------------------------------------On January 1, 2011, we completed the previously announced Plan of Arrangement which resulted in our conversion to a publicly traded E&P company. Based on the Plan of Arrangement trust units were exchanged for common shares on a one-to-one basis. Additionally, as a result of the conversion the TURIP was amended and electing holders of trust unit rights received an option and a restricted right; those not electing received a common share right. These instruments were issued under our Stock Option Plan and our Common Share Rights Incentive Plan; please refer to our Information Circular and Proxy Statement dated November 10, 2010 related to our conversion for more information.Internal Control over Financial ReportingNo changes in our internal control over financial reporting ("ICOFR") were made during the quarter ended December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our ICOFR.Related-Party TransactionsDuring 2010, we incurred $2 million (2009 - $2 million) of legal fees from a law firm of which a partner is also a director of Penn West.Off-Balance-Sheet FinancingWe have off-balance-sheet financing arrangements consisting of operating leases. The operating lease payments are summarized in the Contractual Obligations and Commitments section.Forward-Looking StatementsIn the interest of providing Penn West's securityholders 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.
