These statements refer to our objectives, estimates, expectations, and strategic plans for our future operations. Other than statements of historical facts, all statements included in this Report that address activities, events, or developments that Devon expects, believes, or anticipates may or will occur in the future are forward-looking statements. Such statements are subject to a number of assumptions, risks, and uncertainties, many of which are beyond the control of Devon. We discuss our principal assumptions, risks, and uncertainties in our most recent Form 10-K. We encourage our investors to review and consider those matters as they may cause Devon’s actual results to differ materially from our expectations. The forward-looking statements in this Report are made as of the date of this Report, even if this Report is subsequently made available by us on our website or otherwise. Devon does not undertake any obligation to update the forward-looking statements as a result of new information, future events, or otherwise. Devon’s 2008 Summary Annual Report, Discover the Difference, is a departure in format from our previous annual reports. However, as you turn the pages much of the book should be familiar. You will find a letter to shareholders from Chairman and CEO Larry Nichols, responses to investor questions, articles about significant operating projects and a detailed fold-out section highlighting our oil and gas properties. You also will find consolidated financial statements and five- and 11-year tables of key financial results. What you will not find in this Summary Annual Report are the more than 70 pages of detailed financial information we have included in the past. We also have reduced the number of pages dedicated to what has become known as corporate social responsibility. Corporate social responsibility covers a broad range of topics concerning Devon’s commitment to safety, protecting the environment and being a responsible corporate citizen. Rather than combining all this information in one lengthy book, we now are providing it in three separate reports: this Summary Annual Report, SEC Form 10-K and this year’s Corporate Responsibility Report. This approach reduces printing and distribution costs and allows us to better target information to investors according to their interests. Each of the three documents is intended to stand alone. However, for a comprehensive look at Devon and to help you discover what we believe are important differences to investors, you may choose to read all three. Form 10-K and the Corporate Responsibility Report are available by contacting Investor Relations or by accessing them from Devon’s website at www.devonenergy.com. Letter to Shareholders Dear Fellow Shareholders: 2008 was a year of extremes for Devon and for our industry. In July we saw the benchmark WTI oil price climb to $147 per barrel, its highest level ever. By year end, following the collapse of the credit markets and the resulting impact on the global economy, the price of oil had dropped to near $40 per barrel, its lowest level since 2004. Natural gas prices followed a similar course. This extreme price volatility was reflected in Devon’s financial results. In the third quarter of 2008 we reported the highest quarterly earnings in our history at $2.6 billion. Plummeting product prices in the fourth quarter not only reduced sales revenues but also led to a $10.4 billion non-cash impairment charge to the book value of our oil and natural gas properties. As a result, Devon reported its largest ever quarterly loss of $6.8 billion in the fourth quarter. These events amid deteriorating world economic conditions are a stark reminder of the cyclical nature of our business. Oil and natural gas prices can rise and fall for a multitude of meteorological, political, psychological and economic reasons. Although it is tempting to get caught up in today’s J. Larry Nichols Chairman and Chief Executive Officer headlines and believe that energy markets will never improve again, our experience tells us otherwise. Accordingly, our commitment to manage Devon to achieve sustainable long-term success is unchanged. Long- term supply and demand fundamentals for oil and natural gas remain compelling. World economies will recover, and today’s over-supplies will be absorbed. We are confident that Devon’s financial strength, the durability of our asset base and the abilities of our people will enable us to weather this down cycle and emerge even stronger. Financial Strength Makes a Difference Throughout our history, Devon has taken advantage of periods of strong commodity prices to repay debt and strengthen our balance sheet – 2008 was no exception. With record cash flow and the proceeds from divesting our operations in Africa, we funded exploration and production capital of $8.5 billion, repaid $2.1 billion of debt and repurchased 6.5 million shares of common stock. Among the financial transactions we completed in 2008 was an innovative asset trade with Chevron. In exchange for Devon’s ownership of 14.2 million shares of Chevron common stock, we received $280 million in cash and Chevron’s 44% working interest in the Drunkard’s Wash natural gas field in Utah. The transaction provided additional liquidity and added yet another asset with significant growth potential to our portfolio. We exited 2008 in a strong financial position with $379 million of cash on hand and a net debt to adjusted capitalization ratio of only 24%. Just after year-end 2008, in early January, we increased our capacity of unused credit lines to more than $3 billion. In addition, we have no significant debt maturities until 2011. Growing Reserves with the Drill Bit Devon drilled 2,441 wells in 2008 with 98% success, and the results were exceptional. Excluding price-related reserve revisions, we added 584 million oil-equivalent barrels of proved reserves with the drill bit. That was more than double the 238 million equivalent barrels we produced in 2008. Measured by the associated capital, we added these proved reserves at very competitive finding and development costs. No area contributed more to Devon’s 2008 reserve additions than the Barnett Shale in north Texas. We drilled 659 Barnett Shale wells in 2008, including our 2,000th horizontal well, and added 1.6 trillion cubic feet of natural gas-equivalent reserves with the drill bit. Production from the Barnett also continued its upward trajectory. We increased year-over-year net production 31% compared with 2007 and exited the year producing nearly 1.2 billion cubic feet of gas equivalent per day from our Barnett Shale wells. In east Texas, the success of our horizontal drilling programs drove production to record levels in two key areas during 2008. In the Carthage area, we grew net production 12% to more than 300 million cubic feet of gas per day, and in the Groesbeck area we increased production 41% to more than 100 million cubic feet per day. In Oklahoma, we drove our net Woodford Shale production up 165% to 64 million cubic feet of gas equivalent per day. In the Rocky Mountains, our ongoing development of the Big George coal in the company’s Powder River Basin natural gas project drove production to an all-time high of 100 million cubic feet equivalent per day. In Canada, we steadily ramped up production throughout 2008 from our 100%-owned Jackfish project. Jackfish production is expected to reach 35,000 barrels of oil per day in 2009 and produce at that rate for more than 20 years. In early September we obtained regulatory approval and began site preparation for Jackfish 2, a second 35,000 barrel a day project. We expect to have Jackfish 2 operational in 2011. Also during 2008, we moved forward with all four of our Lower Tertiary discoveries in the deepwater Gulf of Mexico. We continued our development project at Cascade where we expect first production in mid-2010. We drilled successful appraisal wells at Jack, St. Malo and Kaskida, and we expect to select a final joint-development concept for Jack and St. Malo in late 2009 or early 2010. Operational success in North America also has enabled us to reduce our investments in the international arena. We first announced plans to exit Africa in 2007, and in 2008 we finalized the sales of all our African producing properties. Strong oil prices and a robust market for high-quality international properties helped generate after-tax sales proceeds of more than $2 billion. Also in 2008, we redeployed these sales proceeds in emerging growth plays in North America. Among those opportunities is the 1.4 million net- acre position we have built in four new unconventional natural gas plays. This includes 153,000 net acres in Canada’s Horn River Shale, 570,000 net acres in the Haynesville Shale, 112,000 net acres in the Cana-Woodford Shale in Oklahoma and 575,000 net acres in the Cody natural gas play in Montana. These four plays have an aggregate estimated net risked resource potential to Devon of more than 25 trillion cubic feet of gas equivalent. Responding with Caution While 2008 was marked by record oil and gas prices and activity levels, we are dealing with a very different reality in 2009. Oil and natural gas prices have fallen dramatically. We have responded by cutting our 2009 exploration and development capital budget by more than half. This will allow us to preserve our strong balance sheet, yet continue to fund longer-term projects such as the Jackfish 2 oil development in Canada, our four significant Lower Tertiary discoveries in the deepwater Gulf of Mexico and our high-impact exploration program offshore Brazil. These projects will add production in 2010 and beyond when we expect the markets for oil and natural gas to be stronger. In the near term, we believe it is prudent to reduce development drilling on our shorter cycle-time projects in North America. Rather, we will preserve liquidity and maintain our operational capacity so we can respond aggressively when economic conditions rebound. With over 27,000 undrilled locations representing many years of drilling inventory and growth potential, Devon is poised to maintain its position as a leading U.S.- based independent oil and gas producer. A Culture of Success Responsible for Devon’s success are some of the most talented people in our industry. Among their greatest accomplishments is the collaborative culture our employees have all helped to create. Ours is a culture where people exhibit integrity, strive for excellence and have energetic perseverance in the face of obstacles. These attributes were so clearly demonstrated before and after Hurricane Ike struck the Houston area in early September. In addition to caring for the needs of their own homes and families in the wake of the storm, our employees along the coast saw quickly to the safety and preservation of Devon’s oil and gas assets. Following Hurricane Ike, employees donated their time and more than $36,000 to help fellow employees impacted by the storm. It is this can-do spirit that landed Devon on Fortune magazine’s “100 Best Companies to Work For” list for the second consecutive year. When I look to the coming years I have every reason to be optimistic about Devon’s future. In addition to our talented and dedicated staff, we have an unmatched portfolio of oil and gas properties and one of the strongest balance sheets among our peers. As a result of the current economic climate, the oil and natural gas industry is dramatically reducing activity levels. This is setting the stage for a strong recovery in oil and gas prices. And when that time comes, Devon will be positioned to prosper. J. Larry Nichols Chairman and Chief Executive Officer March 20, 2009 A Tribute to John W. Nichols by Larry Nichols The Devon family was deeply saddened by the passing of my father and company co-founder, John W. Nichols, in August. Dad was an innovator with a bold entrepreneurial spirit. The oil and gas industry was his passion, and there are many things for which he will be remembered. In 1950, Dad and three partners began a small oil and gas company named Blackwood & Nichols. From this base he formed the first public oil and gas drilling fund ever registered with the Securities and Exchange Commission. His partnership concept was adopted by many others and became an important funding vehicle for the oil and gas industry. Early investors in the Blackwood & Nichols drilling funds that Dad created were participants in developing natural gas in New Mexico’s San Juan Basin. This later became known as the Northeast Blanco Unit, a field that is still producing nearly 60 years later with Devon as operator. My father’s pioneering spirit continued in 1971, when he asked me to join him in the creation of Devon Energy Corporation. Starting with just four employees and no oil and gas assets, we strategically grew Devon through both good and bad times in the industry. In 1988, we took Devon public. Dad was chairman of the board of directors from 1971 until he was named chairman emeritus in 1999. He received numerous awards and honors throughout his career. Most notable was his induction into the Oklahoma Hall of Fame in 1987. In 2003, the University of Oklahoma honored him with the inaugural Oklahoma Trailblazer Award for outstanding leadership in the energy industry. oil and Gas Investor magazine listed him in 1999 among the “100 Most Influential People of the Petroleum Industry in the Twentieth Century.” John W. Nichols, Chairman Emeritus 1914 – 2008 Today, the company my father co-founded shares many of his attributes – optimism about the future, creativity in solving problems, resourcefulness in exploiting opportunities and above all else, honesty in dealing with everyone. Dad will be truly missed, but his legacy lives on at Devon today.

LASt YeAR ChAnGe (23%) (18%) (22%) (275%) LASt YeAR ChAnGe (37%) 10% 10% (3%) (3%) 9% 10% 6% Discover our Strategy Management Answers Investor Questions Devon reduced its capital budget significantly for 2009. how will this affect your drilling activity and other exploration and production operations? In February, we forecasted our 2009 exploration and production capital budget at $3.5 billion to $4.1 billion. This is less than half the $8.5 billion we invested in these activities in 2008. The reduced 2009 budget reflects a significant reduction in drilling activity and also a much lower investment in lease acquisitions. In 2008, we committed about $1.8 billion to the purchase of unproved acreage that we plan to drill in future years. Given the current low prices of oil and natural gas, we believe it is prudent to curtail drilling until markets show signs of improvement. Rather, we are allocating 35% to 40% of our 2009 exploration and production budget to long-term projects that will not impact current-year production. The longer-term projects include the Jackfish oil sands project in Canada, the deepwater Lower Tertiary exploration and development program in the Gulf of Mexico and deepwater exploration in Brazil. Such longer-term projects add balance to our portfolio and will fuel production growth into the next decade. how has the decline in oil and natural gas prices affected your long-range objectives for Devon? Oil and natural gas prices can be extremely volatile, as the past year so clearly demonstrated. In the near term, this volatility can cause dramatic corrections in our business. The industry ramps up activity when prices rise and reduces activity when prices fall. Devon’s sharp reduction in exploration and production capital spending in 2009 reflects our response to the current low- price environment and concern about the global economy. It also reflects our commitment to preserve liquidity and financial strength. Short-term price volatility does not, however, diminish our confidence in the sustainable future of the oil and natural gas exploration and production business. We firmly believe North American and world demand for energy will continue to grow again as economic conditions improve. Timing is impossible to predict; but when conditions do improve, Devon will be prepared to respond accordingly. Although we have reduced drilling activity in most areas, we have strived to maintain our operational capacity. We remain confident about the future of the energy industry and about Devon’s ability to retain its leadership position among North American independent oil and natural gas producers. how sensitive to changes in oil prices are your projects in the Lower tertiary trend in the Gulf of Mexico and the oil sands in Canada? The price of crude oil is an important element in determining the economics of any oil development project, but price is not the only variable we consider. Capital investment, operating expenses, marketing costs, royalties and taxes are equally important, and no single factor can be considered independently of the others. Experience has taught us that product prices and costs tend to move in tandem. As well-head prices for oil and natural gas rise, service and supply costs also rise. Service contractors, for example, can demand higher day rates for drilling rigs when escalating commodity prices support increased drilling activity. The opposite is true when prices decline. Lower demand for rigs translates into lower day rates. This correlation of commodity prices to the costs of drilling and producing oil and gas means that high- quality projects can achieve acceptable rates of return under a variety of price assumptions. Does this mean that our Lower Tertiary and Jackfish projects would be profitable at any oil price? No, it does not. It does mean, however, that we expect these projects to earn attractive rates of return over their respective life spans. We cannot forecast future commodity prices or costs with precision, but we believe the long-term supply and demand fundamentals for energy will firmly underpin the economics of all of Devon’s long-range projects. now that Devon has divested its African assets, how active is the company outside north America? Devon is primarily a North American company. In 2008, our properties in the United States and Canada accounted for 94% of Devon’s oil and gas production from continuing operations. Most of our production growth in 2008 came from North American development projects such as the Barnett Shale in Texas and Jackfish in Canada. Our growth strategy for the future, however, also includes an annual investment in high-impact exploration projects. As one of North America’s largest independent producers, with proved reserves of more than 2.4 billion oil-equivalent barrels, we believe it is necessary to pursue exploration prospects that are large enough to add meaningful reserve additions. In our search for large-scale projects, we believe investing in select opportunities outside North America can improve our chances of success. After making the decision to exit Africa, we have focused our international exploration attention primarily on offshore Brazil. We have already established oil production there with our Polvo project in the Campos Basin and hold licenses on nine additional offshore exploratory blocks. In six of these licensed blocks we are partnering with Petrobras, Brazil’s national oil company. Offshore Brazil has been the site of significant recent industry discoveries and is believed to contain billions of barrels of potential resources. Devon plans to drill nine exploratory wells in Brazil in 2009 and 2010. What have you learned from your success developing the Barnett Shale that you can apply to other north American shale plays? Having pioneered horizontal drilling in the Barnett and as the leading producer in the play, we believe much of what we have learned will be applicable to emerging shale plays such as the Haynesville, Cana-Woodford and Horn River. One of the important lessons learned was that results can vary considerably within the play. By drilling in the best places we can significantly improve our overall results. A corollary to this lesson is to begin slowly and to learn as much as possible about an area before beginning large-scale development. In the case of the Barnett Shale, we moved cautiously at first until we fully understood our acreage position. In the early years in the Barnett we invested heavily in seismic studies and sought to evaluate and “de-risk” our acreage. Following this de-risking period, the confidence we gained was reflected in better per- well results and significant production growth. With a thorough understanding of the play we were able to prudently accelerate drilling to more than 500 wells per year. We will apply that same approach – beginning with a deliberate pace and increasing our knowledge base – before commencing full-scale development of our emerging shale opportunities. Does Devon plan to invest in alternative energy sources such as wind and solar? Devon’s expertise is finding and producing oil and natural gas; this is something we have been doing successfully since 1971. And although we believe all economically viable sources of energy will be needed to quench the world’s ever-growing appetite, we also believe that clean- burning domestic natural gas and oil will continue to be vital energy sources far into the future. Our focus will remain on efficiently supplying oil and natural gas, the business we know best. Making a Difference Above the Surface Finding and producing natural gas and oil from miles below the surface is among the most challenging endeavors of our time. Devon is successfully applying science and technology to help meet the world’s growing demand for energy. What differentiates us from our peers, however, lies not just in what we do below the surface, but also in how we operate. We have established one of the finest portfolios of producing properties in the industry through innovation, technological drive and entrepreneurial spirit. But that is only part of our objective. To be the nation’s premier independent natural gas and oil producer, we also must be committed to environmental stewardship and to the communities that surround us. Our natural gas production operations in north Texas have emerged as a focal point for water recycling in the energy industry. We pioneered new recycling technology in the Barnett Shale in 2004. Today, water recycling is an integral part of our business with potential for use in shale plays throughout North America. In Canada, we have a fresh-water management and usage policy that outlines our commitment to this important resource. Devon’s Jackfish oil sands project is a prime example of this commitment as the project was designed to use water from a deep saline aquifer, as opposed to shallower, fresh water sources. Jackfish uses water to make steam for its production operations. By using non-potable water we can preserve fresh water supplies for the community. Across North America we are continuing to reduce methane and carbon dioxide emissions by applying new technology to our well sites and pipelines. Since establishing our companywide emissions inventory system at the end of 2007, Devon has identified hundreds of additional opportunities to reduce emissions, which we have begun to implement. Here, a water sample is drawn for testing. Devon is using recycled water in the Barnett Shale to reduce consumption of fresh water. Groesbeck, Texas, with a population of 4,300, is one of many communities where Devon employees live and work. Chris Lee, a Devon employee in Havre, Montana, volunteers his time to coach little league baseball. Working to improve the quality of life in the communities where we live and work extends beyond taking care of the natural environment. It has been a longstanding priority for us to partner with educational institutions in communities where we do business. While we support higher education and public education through substantial financial contributions, the most important gift we give to students is our time. Hundreds of Devon employees volunteer weekly to tutor students from inner-city schools. In Oklahoma City, Mark Twain Elementary School is no longer on the national at-risk list, in part because of the thousands of hours in tutoring time contributed by Devon volunteers. In Houston, Devon volunteers have helped raise test scores by an entire grade level at Thompson Elementary School, where a large percentage of students are homeless. In addition to education, we reach out to emergency responders with funding and equipment donations as well as innovative ideas. Wise Eyes is a program we initiated in Texas in 1993 to help the Wise County sheriff establish a community crime watch program. Devon has taken the model formed through its Wise County partnership and funded similar programs in 28 other communities across five states. It is not enough for Devon to be one of the nation’s most prolific natural gas and oil producers. Although we are headquartered in Oklahoma City, we believe every place we operate is our home. The towns and cities where we do business are the same places we shop, vote, worship and take our children to school. We care about those communities because those communities are important to our employees and their neighbors. By respecting the environment and enhancing quality of life, we can foster the kind of business atmosphere necessary for us to become the nation’s premier independent natural gas and oil producer.

The value of an exploration and production company is ultimately determined by the quality of its natural gas and oil assets. Devon has assembled a producing asset base that is about two-thirds natural gas and one- third liquids. It is also located primarily in North America. In addition to our producing properties we hold more than 19 million net undeveloped acres worldwide that will be the source of future oil and gas reserves and production. Following is a discussion of some of Devon’s more significant oil and gas assets. Barnett Shale Still the King The Barnett Shale field in north Texas is Devon’s most important asset. As the energy industry reaches to identify other non-conventional sources of oil and natural gas, the Barnett Shale is the resource by which the others are measured. Based on relative depth, thickness, porosity and energy content, the Barnett sets a high standard. The Barnett Shale represents nearly 37% of Devon’s total proved reserves and accounted for 28% of the company’s oil and gas production in 2008. As the largest Barnett producer, Devon’s wells account for about a quarter of all the gas from the field. We also are the largest lease holder, controlling 715,000 net acres. Furthermore, some 90% of Devon’s leases are in the most productive parts of the field. 0 In 2008, we drilled a record 659 Barnett Shale wells, driving our total producing well count in the field to more than 3,800 wells. Devon’s net Barnett production approached 1.2 billion cubic feet of gas equivalent per day in late 2008, an all-time high. Although our capital budget calls for drilling fewer wells in the Barnett in 2009, we have no shortage of opportunities. We have more than 7,500 undrilled locations on our Barnett leases and believe we can ultimately increase daily production to as much as 2 billion cubic feet per day. The Barnett Shale is Devon’s most significant producing asset and will continue to be a source of new reserves and production far into the future. Where is the next Barnett Shale? The tremendous success of the Barnett Shale field in north Texas, from which Devon has produced more than 1.5 trillion cubic feet of natural gas equivalent, has launched an industry- wide search for other natural gas shale plays. Reserves and production growth from unconventional reservoirs such as the Barnett Shale is great news for North America. Clean-burning natural gas is both environmentally friendly and becoming increasingly abundant as Devon and other independent producers find and develop new sources of supply. Although it may be difficult to find another unconventional resource with all the same characteristics as the Barnett, some exciting candidates have been identified. Devon has assembled significant acreage positions in four of these emerging plays – the Cana- Woodford, Haynesville and Cody plays in the United States and the Horn River Basin play in Canada. Each has the potential to provide thousands of low- risk drilling opportunities to Devon in the future. We are now in the process of evaluating and “de-risking” our leases in the four new plays. De-risking involves a combination of seismic evaluation, mapping, drilling and data analysis. Through the de-risking process, we expect to determine the best areas to drill and, importantly, where to avoid drilling. In February 2009, Devon announced its entry into the Cana- Woodford Shale in west-central Oklahoma’s Anadarko Basin. Devon is the largest leaseholder in the Cana play with 112,000 net acres. The Cana- Woodford is deeper than the Woodford Shale found in the Arkoma Basin of eastern Oklahoma. We believe the Cana- Woodford Shale may hold more than 200 billion cubic feet of natural gas per square mile, with recovery factors equaling the best shale plays in the country. We have completed more than 10 Cana wells to date, with average expected per well recoveries in excess of 6 billion cubic feet of natural gas. This suggests the risked potential from Devon’s Cana leases could approach 4 trillion cubic feet of gas equivalent. We are very excited about the future of the Cana play and expect to run four rigs there throughout 2009. We also plan to build a processing facility to handle the liquids-rich Cana gas. Another emerging shale play, the Haynesville Shale, spans the border of Texas and northern Louisiana. Devon has assembled an industry-leading lease position of 570,000 net acres in the play. A portion of our Haynesville acreage is a legacy of long-established operations in the Carthage area in east Texas. Devon has drilled and re- completed hundreds of wells in the Carthage area in the past several years, and has increased production to more than 300 million cubic feet of gas equivalent per day. The Haynesville Shale adds yet another layer of potential in Carthage, where Devon already produces from multiple gas- bearing formations.

We expect to run a two-rig drilling program in the Haynesville in 2009, with about 10 wells planned. In the Cody play in south-central Montana, we have assembled a lease position of 575,000 net acres. Of Devon’s three emerging shale plays in the United States, the Cody is the least mature. We have the results of only four completed wells, but plan to complete another four Cody wells in 2009. In northeast British Columbia, Devon has built a lease position of 153,000 net acres in the Horn River Basin shale play. We initiated production from our first pilot well in the play in April 2008. Although located in a remote area, the Horn River Basin is attracting the attention of U.S. and Canadian exploration and production companies. The British Columbia government estimates that Horn River Basin could contain up to 250 trillion cubic feet of gas in place. Devon drilled two horizontal Horn River wells in the first quarter of 2009, and we plan to conduct additional evaluation and de- risking operations throughout the year. Jackfish Success Leads to Jackfish 2 The oil sands of Alberta are estimated to hold as much as 173 billion barrels of recoverable oil. About 20% of this will be recovered through mining techniques. The remaining 80% will be extracted using in situ, or in place, technologies which minimize the surface impact. At Devon’s in situ Jackfish project, we are injecting steam underground to help mobilize the oil to the surface through horizontal wells. We began steam injection at Jackfish in 2007 and ramped up oil production steadily throughout last year, reaching about 22,000 barrels per day in December. Full production of 35,000 barrels per day is expected later in 2009. Jackfish is a resounding success and among the best performing projects of its kind in Canada. Individual Jackfish wells are producing more than 1,600 barrels per day. Jackfish also sets a high environmental standard with its state- of-the-art water-recycling facilities. No fresh water is used to generate steam at Jackfish. Water is supplied from an underground source that is not suitable for drinking or irrigation. The 35,000-barrel-per-day production target at Jackfish is based on the design capacity of the facilities. Construction of a second phase of the project is now under way to further realize the potential of Devon’s oil sands leases. Jackfish 2 is sized to produce another 35,000 barrels per day and ultimately recover approximately 300 million barrels of oil over the more than 20-year life of the project. Devon expects to invest about $1 billion in Jackfish 2 by the time it is operational in 2011. A Cascade of Firsts Cascade was Devon’s first discovery in the Gulf of Mexico’s Lower Tertiary trend. The 2002 deepwater oil discovery led to three more significant Lower Tertiary successes: St. Malo in 2003, Jack in 2004 and Kaskida in 2006. In 2010, Cascade, which is located in the Walker Ridge federal lease area, will become the first of the four projects to begin commercial production. This FPSO, being configured for the Cascade project, will be the first commissioned in the U.S. Gulf of Mexico. Devon and equal partner Petrobras of Brazil sanctioned Cascade for development in 2007. The development plan for Cascade will be carried out in phases, with only two wells initially planned for production. The producing wells will be completed at the seafloor, some 8,000 feet below the surface of the water. The wells will produce into a floating production, storage and offloading vessel, or FPSO – the first of its kind to be commissioned in the Gulf of Mexico. Construction of the FPSO, a refitted oil tanker, is under way in Singapore. As oil begins flowing in 2010, the partners will carefully monitor the wells and the performance of the oil reservoir. A comprehensive, long-range development plan will then be outlined drawing upon information obtained from the initial wells. The Lower Tertiary trend has been heralded as the largest U.S. oil discovery since Prudhoe Bay in Alaska. Devon’s Cascade project is an important milestone in making this new domestic energy resource a reality and making the United States less dependent upon foreign imports. exploring the Depths Most of Devon’s oil and natural gas is produced from large-scale development areas such as the Barnett Shale and Carthage in Texas, Washakie in Wyoming and Lloydminster in Canada. Accordingly, 95% of the wells we drilled in 2008 were development wells. However, the other 5% of the wells we drilled, the exploratory wells, are also important. This is because successful exploration leads to development – as a way of restocking the shelves. In recent years our exploration focus has been on relatively unexplored deepwater areas, notably in the U.S. Gulf of Mexico and offshore Brazil. And we have been successful, especially in the deepwater Gulf. With four significant discoveries in the Lower Tertiary trend and more than 30 additional Lower Tertiary and Miocene prospects, Devon is a leader in this exciting and challenging exploratory frontier. Devon’s Jackfish project in Canada is expected to reach ,000 barrels of oil per day in 00. We also see attractive exploration opportunities offshore Brazil, where we hold interests in 9 licensed blocks comprising 700,000 net acres. In 2008, Devon participated in a discovery on block BM-C-30 in the Campos Basin and we plan to drill an exploratory well on adjoining block BM-C-32 later in 2009. Currently, we are drilling on block BM-BAR-3 in the northern Barreirinhas Basin using a deepwater drillship that Devon has under long-term contract. We expect to drill as many as eight additional exploratory wells in Brazil over the next two years. In summary, Devon has a broad and diverse asset base that provides stable near-term oil and gas production plus abundant opportunities for growth. This platform of established development projects enhanced by our high- impact exploration program positions us for today and for tomorrow. -Year Property Data () Reserves (Net of royalties) Oil (MMBbls) Gas (Bcf) NGLs (MMBbls) Oil, Gas and NGLs (MMBoe) 10% Present Value Before Income Taxes (In millions) (2) $ Production (Net of royalties) Oil (MMBbls) Gas (Bcf) NGLs (MMBbls) Oil, Gas and NGLs (MMBoe) Average Prices (3) Oil (per Bbl) Gas (per Mcf) NGLs (per Bbl) Oil, Gas and NGLs (per Boe) Unit Production and operating expense (per Boe) $ $ $ $ $ 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 Growth Rate Growth Rate 166 1,440 21 427 1,375 20 189 3 55 12.28 1.78 8.08 11.09 439 2,785 55 958 5,316 25 295 5 79 17.78 2.09 13.28 14.22 406 3,045 50 963 17,075 37 417 7 113 24.99 3.53 20.87 22.38 527 5,024 108 1,472 6,687 36 489 8 126 21.41 3.84 16.99 22.19 444 5,836 192 1,609 15,307 42 761 19 188 21.71 2.80 14.05 17.61 530 7,217 209 1,941 20,944 47 858 22 211 26.13 4.52 18.63 26.04 484 7,385 232 1,946 20,950 54 883 24 225 29.12 5.34 23.06 30.38 555 7,192 246 2,000 32,850 46 819 24 206 38.64 7.03 29.05 39.89 634 8,259 275 2,286 22,146 42 808 23 200 57.39 6.03 32.10 40.19 677 8,994 321 2,496 32,852 55 863 26 224 63.98 6.01 37.76 43.08 429 9,885 352 2,428 14,178 53 940 28 238 86.73 7.28 44.08 53.30 4.29 4.15 4.81 5.29 4.71 5.79 6.38 7.65 8.81 9.68 11.52 5-Year Compound 10-Year Compound -4% 6% 11% 5% -8% 2% 2% 5% 2% 27% 10% 19% 15% 15% 10% 21% 33% 19% 26% 10% 17% 25% 16% 22% 15% 18% 17% 10% For more information on Operations: www.devonenergy.com/operations • Detailed maps showing operating areas and statistics • Devon’s marketing and midstream business Operating Statistics by Area () Producing Wells at Year-end 8,578 7,841 6,812 4,200 662 28,093 8,603 479 37,175 Permian Mid- Continent Rocky Mountains Gulf Coast U.S. offshore total U.S. Canada international total Company 2008 Production (Net of royalties) Oil (MMBbls) Gas (Bcf) NGLs (MMBbls) Oil, Gas and NGLs (MMBoe) Average Prices (2) Oil (per Bbl) Gas (per Mcf) NGLs (per Bbl) Oil, Gas and NGLs (per Boe) Year-end Reserves (Net of royalties) Oil (MMBbls) Gas (Bcf) NGLs (MMBbls) Oil, Gas and NGLs (MMBoe) 7 32 2 15 $ $ $ $ 95.88 7.27 40.71 67.69 94 242 27 161 1 383 16 80 98.53 7.35 40.19 43.92 7 5,013 217 1,059 1 109 1 20 88.64 6.31 20.46 41.01 16 1,346 10 250 2 145 5 31 99.13 8.52 46.73 53.25 16 1,378 61 307 6 57 — 16 104.90 9.53 51.11 74.55 34 390 2 101 17 726 24 162 98.83 7.59 41.21 50.55 167 8,369 317 1,878 22 212 4 61 71.04 8.17 61.45 57.65 134 1,510 35 421 14 2 — 15 94.05 8.27 — 92.91 128 6 — 129 53 940 28 238 86.73 7.28 44.08 53.30 429 9,885 352 2,428 Year-end Present value of Reserves (In millions) (3) Before income tax After income tax $ $ 1,132 4,746 1,470 1,641 1,196 10,185 7,381 2,959 2,252 1,034 859 14,178 10,492 Year-end Leasehold (Net acres in thousands) Developed Undeveloped Wells Drilled During 2008 Capital Costs incurred (In millions) (4) 2008 Actual 2009 Forecast 302 534 146 853 559 948 607 1,940 338 536 532 212 187 1,277 2,485 4,842 2,265 5,436 53 9,238 4,803 19,516 23 1,667 721 53 2,441 876 2,920 $ $ 135-160 1,190-1,390 1,082 190-225 1,558 400-450 1,374 830-940 7,810 2,745-3,165 1,656 910-1,060 584 10,050 420-490 4,075-4,715 (1) Excludes results from discontinued operations.
