NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This annual information form contains certain forward-looking statements or information (collectively referred to in this note as "forward-looking statements") within the meaning of applicable securities legislation. Forward-looking statements are typically identified by words such as "projected", "anticipate", "believe", "expect", "plan", "intend" or similar words suggesting future outcomes or statements regarding an outlook. Forward-looking statements in this annual information form include, but are not limited to, statements with respect to: oilsands strategy and the benefits of this strategy, Suffield development plans, potential shut-ins and the possible receipt of royalty credits, the effect of Alberta Energy & Utilities Board commingling guidelines, capital investment levels and the allocation thereof, drilling plans and the timing and location thereof, production capacity and levels and the timing of achieving such capacity and levels, the timing of completion of the Foster Creek and Christina Lake expansions, the anticipated capacities of and the timing of capacity expansions for the Wood River and Borger refineries, anticipated capacity for and timing of expansion of the Steeprock natural gas plant, the development of the Jonah area, the potential for natural gas resource play development on the Foix permit lands, reserves estimates, the level of expenditures for compliance with environmental regulations, site restoration costs including abandonment and reclamation costs, pending litigation, exploration plans, acquisition and divestiture plans, including farmout plans and net cash flows.

        Readers are cautioned not to place undue reliance on forward-looking statements, as there can be no assurance that the plans, intentions or expectations upon which they are based will occur. By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties, both general and specific, that contribute to the possibility that the predictions, forecasts, projections and other things contemplated by the forward-looking statements will not occur. Although EnCana believes that the expectations represented by such forward-looking statements are reasonable, there can be no assurance that such expectations will prove to be correct. Some of the risks and other factors which could cause results to differ materially from those expressed in the forward-looking statements contained in this annual information form include, but are not limited to: volatility of and assumptions regarding oil and natural gas prices, assumptions based upon EnCana's current guidance, fluctuations in currency and interest rates, product supply and demand, market competition, risks inherent in EnCana's North American and foreign oil and natural gas and market optimization operations, risks of war, hostilities, civil insurrection and instability affecting countries in which EnCana and its subsidiaries operate and terrorist threats, risks inherent in EnCana's and its subsidiaries' marketing operations, including credit risk, imprecision of reserves estimates and estimates of recoverable quantities of oil, natural gas and liquids from resource plays and other sources not currently classified as proved reserves, EnCana's and its subsidiaries' ability to replace and expand oil and natural gas reserves, the ability of EnCana and ConocoPhillips to successfully manage and operate the integrated North American heavy oil business and the ability of the parties to obtain necessary regulatory approvals, refining and marketing margins, potential disruption or unexpected technical difficulties in developing new products and manufacturing processes, potential failure of new products to achieve acceptance in the market, unexpected cost increases or technical difficulties in constructing or modifying manufacturing or refining facilities, unexpected difficulties in manufacturing, transporting or refining synthetic crude oil, risks associated with technology, EnCana's ability to generate sufficient cash flow from operations to meet its current and future obligations, EnCana's ability to access external sources of debt and equity capital, general economic and business conditions, EnCana's ability to enter into or renew leases, the timing and costs of construction of gas storage facilities, wells and pipelines, EnCana's ability to make capital investments and the amounts of capital investments, imprecision in estimating the timing, costs and levels of production and drilling, the results of exploration, development and drilling, imprecision in estimates of future production capacity, EnCana's and its subsidiaries' ability to secure adequate product transportation, uncertainty in the amounts and timing of royalty payments, imprecision in estimates of product sales, changes in environmental and other regulations or the interpretation of such regulations, risks associated with existing and potential future lawsuits and regulatory actions against EnCana and its subsidiaries, political and economic conditions in the countries in which EnCana and its subsidiaries operate, difficulty in obtaining necessary regulatory approvals and such other risks and uncertainties described from time to time in EnCana's reports and filings with the Canadian securities authorities and the United States Securities and Exchange Commission (the "SEC"). Statements relating to "reserves" are deemed to be forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the reserves

described exist in the quantities predicted or estimated, and can be profitably produced in the future. Readers are cautioned that the foregoing list of important factors is not exhaustive. The forward-looking statements contained in this annual information form are made as of the date hereof and, except as required by law, EnCana undertakes no obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The forward-looking statements contained in this annual information form are expressly qualified by this cautionary statement.

NOTE REGARDING RESERVES DATA AND OTHER OIL AND GAS INFORMATION

        National Instrument 51-101 ("NI 51-101") of the Canadian Securities Administrators imposes oil and gas disclosure standards for Canadian public companies engaged in oil and gas activities. NI 51-101 and its companion policy specifically contemplate the granting of exemptions from some of the disclosure standards prescribed by NI 51-101 to companies that are active in the U.S. capital markets, to permit the substitution of the standards required by the SEC in order to provide for comparability of oil and gas disclosure with that provided by U.S. and other international issuers. EnCana has obtained an exemption from Canadian securities regulatory authorities to permit it to provide disclosure in accordance with the relevant legal requirements of the SEC. Accordingly, the reserves data and other oil and gas information included or incorporated by reference in this annual information form is disclosed in accordance with U.S. disclosure requirements and practices. Such information, as well as the information that EnCana discloses in the future in reliance on the exemption, may differ from the corresponding information prepared in accordance with NI 51-101 standards.

        The primary differences between the U.S. requirements and the NI 51-101 requirements are that (i) the U.S. standards require disclosure only of proved reserves, whereas NI 51-101 requires disclosure of proved and probable reserves, and (ii) the U.S. standards require that the reserves and related future net revenue be estimated under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made, whereas NI 51-101 requires disclosure of proved reserves and the related future net revenue estimated using constant prices and costs as at the effective date of the estimation, and of proved and probable reserves and related future net revenue using forecast prices and costs. The definitions of proved reserves also differ, but according to the Canadian Oil and Gas Evaluation Handbook (the reference source for the definition of proved reserves under NI 51-101), differences in the estimated proved reserves quantities based on constant prices should not be material. EnCana concurs with this assessment.

        EnCana has disclosed proved reserves quantities using the standards contained in SEC Regulation S-X, and the standardized measure of discounted future net cash flows relating to proved oil and gas reserves determined in accordance with United States Statement of Financial Accounting Standards No. 69 "Disclosures About Oil and Gas Producing Activities" ("SFAS 69").

        Under U.S. disclosure standards, reserves and production information is disclosed on a net basis (after royalties). The reserves and production information contained in this annual information form is shown on that basis.

        In this annual information form, certain crude oil and natural gas liquids ("NGLs") volumes have been converted to millions of cubic feet equivalent ("MMcfe") or thousands of cubic feet equivalent ("Mcfe") on the basis of one barrel ("bbl") to six thousand cubic feet ("Mcf"). Also, certain natural gas volumes have been converted to barrels of oil equivalent ("BOE") on the same basis. MMcfe, Mcfe and BOE may be misleading, particularly if used in isolation. A conversion ratio of one bbl to six Mcf is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent value equivalency at the well head.

GENERAL DEVELOPMENT OF THE BUSINESS

        EnCana is one of North America's leading natural gas producers, is among the largest holders of natural gas and oil resource lands onshore North America and is a technical and cost leader in the in-situ recovery of oilsands bitumen. EnCana's other operations include the transportation and marketing of crude oil, natural gas and natural gas liquids, as well as the refining of crude oil and the marketing of refined petroleum products. EnCana pursues profitable growth from its portfolio of long-life resource plays situated in Canada and the United States. The Corporation is also engaged in select exploration activities internationally.

        Following the Merger in 2002, the majority of EnCana's Upstream operations were located in Canada, the U.S., Ecuador and the U.K. central North Sea. From the time of the Merger through early 2004, EnCana focused on the development and expansion of its highest growth, highest return assets in these key areas. Beginning in 2004, EnCana sharpened its strategic focus to concentrate on its inventory of North American resource play assets. As part of its ongoing strategic focus, the Corporation has completed a number of acquisitions while continuing with the divestiture of its non-core assets. A portion of the divestiture proceeds were used to fund EnCana's normal course issuer bid program. In 2006, EnCana purchased approximately 85.6 million shares under the program for a total cost of approximately $4.2 billion.

        In January of 2007, EnCana, with ConocoPhillips, completed the creation of an integrated heavy oil business. This venture provides greater certainty of execution for EnCana's oilsands projects and gives EnCana immediate participation in the North American refining industry.

        Effective January 1, 2007, EnCana has been reorganized into six operating divisions:

•

Canadian Plains Division, which includes the majority of EnCana's legacy oil and gas assets



•

Canadian Foothills Division, which includes the majority of EnCana's Canadian natural gas resource plays



•

USA Division, which includes the majority of the Corporation's upstream U.S. assets, including its key resource plays



•

Integrated Oilsands Division, which includes all of the assets within the newly created integrated heavy oil business (including the U.S. refinery assets), as well as the Corporation's other oilsands interests and the natural gas assets on the Cold Lake Air Weapons Range



•

Offshore & International Division, which includes the Corporation's offshore East Coast Canadian assets as well as assets in Brazil, the Middle East, Greenland and France



•

Midstream & Marketing Division, which continues to provide coordination of the Corporation's natural gas and crude oil market optimization activities, and includes the Cavalier and Balzac power assets

        In 2006, for financial reporting purposes, EnCana has defined its operations into the following segments: (i) Upstream; (ii) Market Optimization; and (iii) Corporate. All divisions are reported under Upstream with the exception of the Midstream & Marketing Division, which is reported under Market Optimization. In 2007, the Integrated Oilsands Division will be reported under a new Integrated Oilsands segment.

        The following describes the significant events of the last three years. In this section, all divestiture proceeds are provided on a before tax basis unless otherwise noted.

2006 Projects:

•

In November 2005, EnCana announced plans to examine a number of proposals from other companies who were interested in participating in the development of EnCana's oilsands assets. In October 2006, EnCana announced it had entered into an agreement with ConocoPhillips to create an integrated heavy oil business consisting of upstream and downstream assets.

The creation of the integrated heavy oil business was completed on January 3, 2007. The business is comprised of two 50/50 operating entities, one Canadian upstream enterprise managed by EnCana and one U.S. downstream enterprise managed by ConocoPhillips, with both EnCana and ConocoPhillips

NARRATIVE DESCRIPTION OF THE BUSINESS

        The following map outlines EnCana's onshore North America landholdings and key resource plays as of December 31, 2006. The map also identifies the Borger and Wood River refineries that were contributed to the integrated heavy oil business by ConocoPhillips in January 2007.

8

---

        The vast majority of EnCana's operations are located in Canada and the U.S., while the Offshore & International Division is mainly focusing on opportunities off the East Coast of Canada, in Brazil, the Middle East, Greenland and France.

        At December 31, 2006, EnCana had net proved reserves of approximately 12.4 trillion cubic feet of natural gas and 1.1 billion barrels of crude oil, bitumen and NGLs, as estimated by independent qualified reserves evaluators. Proved developed reserves comprise approximately 62 percent of total natural gas reserves, approximately 75 percent of crude oil and NGLs reserves excluding bitumen and approximately 13 percent of bitumen reserves. See "Reserves and Other Oil and Gas Information" in this annual information form.

        Within western Canada, EnCana has an industry-leading land position of approximately 23.8 million gross acres (approximately 21.0 million net acres, of which approximately 12.1 million net acres are undeveloped). The mineral rights on approximately 38 percent of the total net acreage is owned in fee title by EnCana, which means that production is subject to a mineral tax that is generally less than the Crown royalty imposed on production from land where the government owns the mineral rights. In 2006, EnCana had core capital expenditures in Canada of approximately $4,015 million ($3,984 million in western Canada) and drilled approximately 3,009 net wells (3,007 in western Canada).

        In the U.S., EnCana's landholdings are approximately 6.4 million acres (approximately 5.5 million net acres, of which approximately 5.0 million net acres are undeveloped), with the majority in Colorado, Wyoming, Washington and Texas. In 2006, EnCana had core capital expenditures of approximately $2,061 million and drilled approximately 639 net wells within the U.S.

        As noted previously, EnCana's operations are divided into six divisions. The following narrative describes each division in greater detail.

Canadian Plains Division

        The Canadian Plains Division encompasses the majority of EnCana's legacy natural gas production activities in southern Alberta and Saskatchewan as well as the Corporation's crude oil (excluding in-situ oilsands) development and production activities in Alberta and Saskatchewan. Two key resource plays are located in the Canadian Plains Division: (i) Shallow Gas; and (ii) Pelican Lake. The Shallow Gas key resource play is contained within the Suffield, Langevin and Brooks North areas.

        In 2006, the Canadian Plains Division had core capital expenditures of approximately $768 million and drilled approximately 1,635 net wells. EnCana's 2007 core capital investment in the Canadian Plains Division is projected to be approximately $870 million, which includes the drilling of approximately 2,100 net wells.

        The following table summarizes landholdings for the Canadian Plains Division as at December 31, 2006.

At December 31, 2006, the Shallow Gas key resource play had 20,192 gross producing gas wells (19,682 net gas wells).

        The following describes EnCana's major producing areas or activities in the Canadian Plains Division.

Suffield

        EnCana holds interests in the Upper Cretaceous shallow natural gas horizons and deeper formations in the Suffield area in southeast Alberta. Suffield is one of the core areas of the Shallow Gas key resource play. EnCana also produces conventional heavy oil in the area. The Suffield area is largely made up of the Suffield Block, where operations are carried out by EnCana in cooperation with the Canadian military according to guidelines established under agreements with the Government of Canada. EnCana plans to continue development of its shallow gas and heavy oil resources at Suffield. In 2007, as part of its ongoing application to continue shallow gas infill drilling in the National Wildlife Area, EnCana will be preparing an Environmental Impact Statement and participating in an Alberta Energy & Utilities Board ("EUB") joint panel hearing as part of the Canadian Environmental Assessment Act. In 2006, EnCana drilled approximately 460 net wells in the area and production averaged approximately 241 million cubic feet per day of natural gas.

Brooks North

        EnCana produces natural gas, crude oil and NGLs from the Cretaceous horizons in the Brooks area of southern Alberta, located east of Calgary. This area is another core area of the Shallow Gas key resource play and is largely comprised of EnCana fee title lands. In 2006, EnCana drilled approximately 473 net wells in the

area and production averaged approximately 272 million cubic feet per day of natural gas. Completion operations in 2007 are expected to benefit significantly from the recent EUB self-declared commingling process, which became effective December 15, 2006. It is anticipated that the new process will allow EnCana to complete additional zones in a well bore at minimal incremental cost.

Langevin

        The Langevin area produces predominantly shallow gas from the Upper Cretaceous formations in southeast Alberta and southwestern Saskatchewan. Certain parts of this area are included in EnCana's Shallow Gas key resource play. Development of this area focuses on infill drilling and optimization of existing wells, and is largely comprised of EnCana fee title lands. In 2006, EnCana drilled approximately 426 net wells in the area and production averaged approximately 238 million cubic feet per day of natural gas.

Drumheller

        EnCana produces natural gas, crude oil and NGLs from the Cretaceous horizons in the Drumheller area of southern Alberta. The area is mainly a conventional Mannville gas play, and is largely comprised of EnCana fee title lands. In 2006, EnCana drilled approximately 167 net wells in the area and production averaged approximately 104 million cubic feet per day of natural gas.

Pelican Lake

        Pelican Lake is one of EnCana's key resource plays producing crude oil in northeast Alberta. In 2006, EnCana continued to expand its waterflood program to approximately 80 percent of the field at Pelican Lake, while expanding the polymer pilot from 11 injection wells to 37 injection wells. In order to process the increased fluid volumes associated with the waterflood and polymer projects, EnCana has expanded the facility infrastructure, with additional facility projects to be completed in 2007. EnCana reached payout at Pelican Lake in 2006, changing the royalty from one percent of gross revenues to 25 percent of net revenues. The success of the waterflood program at Pelican Lake increased 2006 crude oil production by approximately five percent compared to 2005; however, because EnCana reached payout, after-royalties production decreased.

        EnCana also holds a 38 percent non-operated interest in a 110-kilometre, 20-inch diameter crude oil pipeline which connects the Pelican Lake area to a major pipeline that transports crude oil from northern Alberta to crude oil markets.

Weyburn

        EnCana has a 62 percent working interest (50 percent economic interest) in the unitized portion of the Weyburn crude oil field in southeast Saskatchewan. EnCana is the operator and expects to improve ultimate recovery in the enhanced oil recovery area of the field with a carbon dioxide ("CO₂") miscible flood project. In 2006, EnCana focused on continuing its infill drilling program with 56 new wells in the unit. As of December 31, 2006, there were 44 patterns on CO₂ injection out of a planned total of 75 patterns.

Canadian Foothills Division

        The Canadian Foothills Division includes EnCana's key natural gas growth assets in British Columbia and Alberta. Four key resource plays are located in the Canadian Foothills Division: (i) Greater Sierra; (ii) Cutbank Ridge; (iii) Bighorn; and (iv) Coalbed Methane Integrated ("CBM Integrated"). The CBM Integrated key resource play (Horseshoe Canyon coalbed methane and commingled shallow gas), is completely contained within the Clearwater business unit.

        In 2006, the Canadian Foothills Division had core capital expenditures of approximately $2,467 million and drilled approximately 1,274 net wells. EnCana's 2007 core capital investment in the Canadian Foothills Division is projected to be approximately $2,150 million, which includes the drilling of approximately 1,370 net wells.

        The following describes EnCana's major producing areas or activities in the Canadian Foothills Division.

Greater Sierra

        The Greater Sierra area of northeast British Columbia is one of EnCana's key natural gas resource plays. Average natural gas production in the area was approximately 213 million cubic feet per day in 2006. Production has remained relatively constant over the past two years as EnCana has reduced capital expenditures, and is currently targeting a drilling program that will continue to maintain current production levels. EnCana is selectively farming out a small portion of its Greater Sierra land position to third parties.

        As at December 31, 2006, EnCana held an average 99 percent interest in 13 production facilities in the area that were capable of processing approximately 486 million cubic feet per day of natural gas. EnCana also holds a 100 percent interest in the Ekwan pipeline which has a capacity of approximately 400 million cubic feet per day and transports natural gas from northeast British Columbia to Alberta.

Cutbank Ridge

        Cutbank Ridge is a key natural gas resource play located in the Canadian Rocky Mountain foothills, southwest of Dawson Creek, British Columbia. Key producing horizons in Cutbank Ridge include the Cadomin, Doig and Montney zones. The majority of the Corporation's lands in this area were purchased in 2003. In 2006, EnCana drilled approximately 116 net natural gas wells at Cutbank Ridge and production averaged approximately 170 million cubic feet per day of natural gas.

        In 2006, a significant extension to the Cutbank Ridge resource play was added with the addition of the Montney zone. EnCana has had a small number of wells producing from the Montney formation as far back as 1999, and the application of new technologies has started to achieve positive results within the formation. At year end 2006, approximately 18 percent of the wells in Cutbank Ridge were producing out of the Montney formation, with 58 wells (25 drilled in 2006) producing approximately 43 million cubic feet of natural gas per day.

        In order to facilitate increased production from Cutbank Ridge, EnCana completed phase one of the Steeprock natural gas processing plant in the fourth quarter of 2006. The plant, located approximately 60 kilometres south of Dawson Creek, British Columbia, is expected to have a licensed capacity of 198 million cubic feet of natural gas per day once both phases are complete. Phase one of the plant has a capacity of approximately 70 million cubic feet per day with a current throughput of approximately 60 million cubic feet per day. EnCana anticipates that phase two will be completed in the first half of 2008.

Bighorn

        The Bighorn area in west central Alberta is another of EnCana's key natural gas resource plays, focusing on exploitation of multi-zone stacked Cretaceous sands in the Deep Basin. EnCana has an average working interest of approximately 60 percent in approximately 1,035,000 gross acres (625,000 net acres) of land in the Bighorn area. The primary producing properties in Bighorn are Wild River, Resthaven, Kakwa, and Berland. In 2006, EnCana drilled approximately 52 net wells in the area and production averaged approximately 91 million cubic feet per day of sweet natural gas.

        EnCana has a working interest in a number of gas plants within Bighorn. The Wild River plant, in which EnCana holds a 70 percent working interest, was expanded to a capacity of approximately 30 million cubic feet per day in January 2006. In April 2006, the Resthaven plant, in which EnCana has a 65 percent working interest, was brought on stream, with a capacity of approximately 100 million cubic feet of natural gas per day. The Kakwa gas plant, with a capacity of approximately 30 million cubic feet per day, was commissioned in September 2006, and operated at close to capacity through the fourth quarter of 2006. EnCana owns 50 percent of this plant and has firm processing capacity for the remaining 50 percent. The Berland River plant was recently expanded, and EnCana now has a 24 percent working interest and approximately 40 million cubic feet per day net capacity.

        The new commingling guidelines announced by the EUB in December 2006, have a positive impact on operations in the business unit. The majority of Bighorn's land base falls within the EUB's Deep Basin

Development Entity No. 2. The primary benefits for the business unit are significant cost reductions on new well completions and the potential to access additional zones with the same number of fractures.

Clearwater

        The Clearwater business unit extends from the U.S. border to just north of Edmonton, and was created by merging the former Chinook and Parkland business units. The primary focus of Clearwater is the CBM Integrated key natural gas resource play; however, Clearwater is also charged with the development of the Mannville coalbed methane fairway, and deeper Cretaceous reservoirs. EnCana holds a combination of both fee lands, where it owns the mineral rights, and crown lands within Clearwater. In 2006, EnCana drilled 729 net CBM Integrated wells, and production averaged approximately 194 million cubic feet per day of natural gas from the CBM Integrated resource play.

Sexsmith/Hythe/Saddle Hills

        EnCana produces natural gas, crude oil and NGLs in the Sexsmith/Hythe/Saddle Hills area in northwest Alberta. EnCana also operates and has a 62 percent interest in the 210 million cubic feet per day Sexsmith sour natural gas and liquids processing plant and an 85 percent interest in the 50 million cubic feet per day Saddle Hills sweet natural gas plant. EnCana also owns 100 percent of and operates the Hythe sour natural gas plant, which has a capacity of approximately 170 million cubic feet per day. The Hythe and Sexsmith sour natural gas plants are interconnected by pipeline to provide greater operating efficiencies. EnCana also owns and operates a 275-kilometre natural gas gathering system in the area.

USA Division

        EnCana's operations in the USA Division are focused on exploiting long-life unconventional natural gas formations in the Jonah field in southwest Wyoming, the Piceance Basin in northwest Colorado and the East Texas, Fort Worth and Maverick Basins in Texas. The Corporation also has landholdings in the Columbia River Basin in Washington State. The majority of the production in the USA Division is from the following four key resource plays: (i) Jonah; (ii) Piceance; (iii) East Texas; and (iv) Fort Worth. The USA Division also has interests in natural gas gathering and processing assets, primarily in Colorado, Wyoming, Texas and Utah.

        In 2006, the USA Division had core capital expenditures of approximately $2,061 million and drilled approximately 639 net wells. EnCana's 2007 core capital investment in the USA Division is projected to be approximately $1,890 million, which includes the drilling of approximately 660 net wells.

        The following table summarizes landholdings for the USA Division as at December 31, 2006.

        The following describes EnCana's major producing areas or activities in the USA Division.

Jonah

        EnCana produces natural gas and associated NGLs from the Jonah field, located in the Green River Basin in southwest Wyoming. The Jonah key resource play produces from the Lance formation, which contains vertically stacked sands that exist at depths between 8,500 and 11,500 feet. The wells are stimulated with multi-stage advanced hydraulic fracturing techniques.

        In March 2006, EnCana obtained a favorable Environmental Impact Statement regulatory approval from the U.S. Bureau of Land Management. The approval provides EnCana access to 600 remaining 10-acre spacing locations and additional locations at tighter spacing, as required, to achieve optimal recovery. In 2006, EnCana drilled approximately 163 net wells in the Jonah area, up from 104 net wells in 2005. Daily production of natural gas averaged approximately 464 million cubic feet in 2006 compared to approximately 435 million cubic feet in 2005.

Piceance

        The Piceance Basin in northwest Colorado is one of EnCana's key natural gas resource plays. The basin is characterized by thick natural gas accumulations primarily in the Williams Fork formation. The May 2004 acquisition of Tom Brown included properties and natural gas production in the basin. In 2006, EnCana drilled approximately 220 net wells in the basin, compared to 266 in 2005. Despite drilling fewer wells in 2006, production of natural gas has grown to an average of approximately 326 million cubic feet per day from approximately 307 million cubic feet per day in 2005.

        In 2006, EnCana finalized four agreements to jointly develop portions of the Piceance Basin. Over the next three years, it is expected that EnCana will drill approximately 267 wells with outside funds and EnCana's partners will fund the drilling of approximately 182 wells, allowing the third parties to earn approximately 20,000 net acres.

15

---

East Texas

        EnCana produces natural gas and associated NGLs in the East Texas Basin. The East Texas properties were acquired as part of the Tom Brown acquisition in 2004, and the basin is one of EnCana's key resource plays. In July 2006, EnCana increased its working interest in the Deep Bossier play in East Texas from 30 percent to 50 percent through a property acquisition. This tight gas, multi-zone play targets the Bossier and Cotton Valley zones. During 2006, EnCana drilled approximately 59 net wells in the basin and production averaged approximately 99 million cubic feet per day of natural gas.

Fort Worth

        EnCana produces natural gas and associated NGLs in the Fort Worth Basin in north Texas. The Fort Worth Basin is one of EnCana's key resource plays. Since entering the area in 2003, the Corporation has assembled a significant land position in the Barnett Shale play in this basin. EnCana is applying horizontal drilling and multi-stage reservoir stimulation to improve performance in this play. In the fourth quarter of 2005, a subsidiary of EnCana completed the purchase of additional development land and producing properties in the basin. EnCana drilled approximately 97 net wells in the basin in 2006 and production averaged approximately 101 million cubic feet per day of natural gas.

Maverick Basin

        EnCana controls approximately 479,000 undeveloped gross acres (339,000 net acres) in the Maverick Basin of southwest Texas. This acreage, purchased in September 2005 for approximately $148 million, contains significant exploratory potential in the Pearsall Shale, plus multi-zone potential in the uphole section. In 2007, the Corporation expects to drill up to six wells, both vertical and horizontal, to assess this potential shale play.

Columbia River Basin

        EnCana holds approximately 823,000 undeveloped gross acres (811,000 net acres) in the Columbia River Basin in Washington State. This sedimentary basin is covered with 5,000 to 15,000 feet of volcanic basalt and as a result it is relatively under-explored. In 2006, EnCana drilled two wells to a depth of approximately 14,000 feet. Log and completions data obtained from these wells is currently under review. A third well is being drilled on the play, and is expected to reach total depth in the second quarter of 2007. EnCana's operations in the Columbia River Basin are largely funded by an outside partner who will eventually earn an interest in this play.

Gathering & Processing Facilities

        EnCana owns and operates various gas gathering and processing facilities. Near Rifle, Colorado, EnCana owns a refrigeration plant with a capacity of approximately 440 million cubic feet per day and over 675 kilometres of pipelines. The Corporation's gathering and processing facilities near Rangely, Colorado, include over 1,620 kilometres of pipelines and a processing facility with a capacity of approximately 60 million cubic feet per day. In Texas, EnCana's gathering facilities include field compression and over 360 kilometres of pipelines. Near Ft. Lupton, Colorado, the gathering and processing facilities include field compression, over 1,000 kilometres of pipelines and a processing facility with a capacity of approximately 90 million cubic feet per day. Near Moab, Utah, EnCana owns a cryogenic natural gas processing plant with a capacity of approximately 60 million cubic feet per day. In west central Wyoming, EnCana has field compression, over 500 kilometres of pipelines and a refrigeration facility with a capacity of approximately 70 million cubic feet per day.

Integrated Oilsands Division

        The Integrated Oilsands Division includes all of the assets within the newly created integrated heavy oil business with ConocoPhillips described below, as well as the Corporation's other oilsands interests and the natural gas assets on the Cold Lake Air Weapons Range. The Division has assets in both Canada and the United States, and contains two key crude oil resource plays: (i) Foster Creek; and (ii) Christina Lake. As at December 31, 2006, the Corporation held oilsands rights of approximately 860,000 gross acres (754,000 net acres) within the Athabasca and Cold Lake oilsands areas, as well as the exclusive rights to lease an additional 505,000 net acres on the Cold Lake Air Weapons Range.

16

---

        In 2006, the Integrated Oilsands Division had core capital expenditures of approximately $745 million and drilled approximately 98 net wells (eight oil wells and 90 gas wells). EnCana's 2007 core capital investment in the Integrated Oilsands Division is projected to be approximately $850 million which includes approximately $770 million related to the drilling of approximately 32 net wells and refinery expansion projects associated with the newly created integrated heavy oil business.

        The information relating to landholdings, production and producing wells in the following tables is as of December 31, 2006, prior to the contribution of Foster Creek and Christina Lake into the integrated heavy oil business with ConocoPhillips.

        The following describes EnCana's major producing areas or activities in the Integrated Oilsands Division.

Cold Lake Air Weapons Range

        EnCana produces natural gas from the Cold Lake Air Weapons Range located in northeast Alberta. EnCana holds surface access and natural gas rights for exploration, development and transportation from areas within the Cold Lake Air Weapons Range which were granted by the Government of Canada. The majority of EnCana's natural gas production in the area is processed through wholly owned and operated compression facilities. In 2006, natural gas production was impacted by the September 2003 EUB decision to shut-in natural

gas production that may put at risk the recovery of bitumen resources in the area. The decision resulted in a decrease in annualized natural gas production of approximately 22 million cubic feet per day in 2006, and 22 million cubic feet per day in 2005. No additional wells were shut-in during 2005 or 2006. The Alberta Government's Department of Energy ("ADOE") is providing financial assistance in the form of a royalty credit, which is equal to approximately 50 percent of the cash flow lost as a result of the shut-in wells.

        There is a potential that approximately 13 million cubic feet per day of natural gas production will be shut-in commencing in April 2007, due to additional risk of recovery of the bitumen resources in the area. A hearing on this matter is expected to commence in February 2007.

Foster Creek

        As of December 31, 2006, EnCana had a 100 percent working interest in Foster Creek, one of the Corporation's key crude oil resource plays. EnCana holds surface access rights from the Governments of Canada and Alberta and oilsands rights for exploration, development and transportation from areas within the Cold Lake Air Weapons Range which were granted by the Government of Alberta. Additionally, EnCana has the exclusive rights to lease several hundred thousand acres of oilsands rights in other areas on the Cold Lake Air Weapons Range. EnCana is currently operating a thermal oil recovery project in the Foster Creek area using steam-assisted gravity drainage ("SAGD") technology.

        In the fourth quarter of 2006, EnCana completed the second stage of an expansion that added an additional 20,000 barrels per day of capacity, increasing production capacity at Foster Creek to approximately 60,000 barrels per day. Current expansions already underway are expected to increase production capacity to approximately 120,000 barrels per day by the end of 2009.

        EnCana continues to research and develop technologies to increase recovery and decrease the costs of extracting crude oil bitumen from oilsands. One focus area is alternate methods of artificial lift where EnCana is operating new pump designs that are expected to enable the Corporation to optimize SAGD performance by operating at lower pressures, thereby realizing lower steam-oil ratios and decreasing facility capital costs. At December 31, 2006, EnCana had 45 wells on electrical submersible pumps at Foster Creek, and the Corporation expects to continue to utilize this technology on new SAGD wells.

        EnCana is also focused on reducing its reliance on steam in bitumen production. EnCana has piloted two technologies using solvents as part of the extraction process. The Vapex process, which uses solvent in place of steam, was piloted at Foster Creek from 2002 to 2005. Results from the Vapex pilot are being utilized during investigations into new production strategies for bitumen recovery. The Solvent Aided Process ("SAP") is discussed in the Christina Lake section below.

        EnCana continues to operate its 80 megawatt, natural gas-fired cogeneration facility in conjunction with its SAGD operation at Foster Creek. The steam generated by the facility is being used within the SAGD operation and the excess power generated is being sold into the Alberta Power Pool grid.

Christina Lake

        Christina Lake is one of EnCana's newest key resource plays. As of December 31, 2006, EnCana had a 100 percent owned thermal crude oil recovery pilot project at Christina Lake that also uses SAGD technology. In 2006, the Corporation approved an expansion that is expected to increase production capacity to approximately 18,000 barrels per day by the second half of 2008. In 2006, EnCana completed the installation of a remote water disposal system for the plant.

        In 2004, EnCana commenced a pilot SAP program at Christina Lake. This process mixes a small amount of solvent with steam to enhance recovery. EnCana continues to produce and monitor current SAP pilot wells and recently began work with another SAP well test in the main reservoir.

Borealis

        EnCana has a 100 percent working interest in approximately 338,000 acres in the Borealis area, which is located approximately 90 kilometres north of Fort McMurray. Borealis is not included in the venture with

ConocoPhillips. Since 2000, the Corporation has drilled approximately 190 delineation wells in the area as of December 31, 2006. In 2007, EnCana plans to continue its stratigraphic well program by drilling approximately 50 wells to further delineate these lands. Environmental work is ongoing to support future applications for development.

Integrated Heavy Oil Business

        On January 3, 2007, EnCana completed the creation of an integrated heavy oil business with ConocoPhillips. The integrated heavy oil business includes Canadian upstream assets contributed by EnCana and U.S. downstream assets contributed by ConocoPhillips.

        The upstream portion of the integrated heavy oil business is conducted through FCCL Oil Sands Partnership (the "Upstream Partnership") which owns the Foster Creek and Christina Lake oilsands projects contributed by EnCana. EnCana and ConocoPhillips each own 50 percent of the Upstream Partnership. EnCana is the operating and managing partner of the Upstream Partnership. The downstream portion of the integrated heavy oil business is conducted through WRB Refining LLC ("WRB") which owns the Wood River and Borger refineries contributed by ConocoPhillips. EnCana and ConocoPhillips each own 50 percent of WRB; however, ConocoPhillips will hold a disproportionate economic interest in the Borger refinery for two years: 85 percent in 2007 and 65 percent in 2008. ConocoPhillips is the operator and manager of WRB. The Upstream Partnership has a Management Committee, while WRB has a Board of Directors; both are comprised of three EnCana and three ConocoPhillips representatives, with each company holding equal voting rights.

        The goal of the Upstream Partnership is to increase current production of approximately 50,000 barrels per day to approximately 400,000 barrels per day of bitumen by 2015, with the intention to transport and sell the bitumen at major Alberta trading hubs.

        The Borger refinery, located in Borger, Texas, has a current capacity of approximately 146,000 barrels per day of crude oil and approximately 50,000 barrels per day of NGLs. It processes mainly light-sour and medium-sour crude oil and NGLs that it receives from North American pipeline systems to produce gasoline, diesel and jet fuel, and natural gas liquids and solvents. The refined products are transported via pipelines to markets in Texas, New Mexico, Colorado and the mid-continent.

        The Wood River refinery, located in Roxana, Illinois, has a current throughput of approximately 306,000 barrels per day, including approximately 30,000 barrels per day of bitumen capacity. It processes a mix of light-low-sulfur and heavy-high-sulfur crude oil that it receives from North American crude oil pipelines to produce gasoline, diesel and jet fuel, petrochemical feedstock and asphalt. The gasoline and diesel are transported via pipelines to markets in the Midwest. The remaining products are transported via pipeline, truck, barge and railcar to markets in the Midwest.

        The goal of WRB is to expand heavy oil processing capacity at the Wood River and Borger facilities from approximately 60,000 barrels per day to approximately 550,000 barrels per day (30,000 to 275,000 barrels per day of bitumen handling capacity) by 2015. WRB plans to purchase and transport all feedstocks for the refineries and sell the refined products.

Offshore & International Division

        EnCana invests a small portion of its capital in exploration opportunities beyond its core geographic areas, primarily off the East Coast of Canada, in Brazil, the Middle East, Greenland and France. In 2006, EnCana's Offshore & International Division had core capital expenditures of approximately $106 million and drilled approximately four net wells. EnCana's 2007 core capital investment in the Offshore & International Division is projected to be approximately $88 million, which includes the drilling of approximately five net wells.

East Coast of Canada

        At December 31, 2006, EnCana held an interest in approximately 2.7 million gross acres (1.7 million net acres) offshore the East Coast of Canada, which includes Nova Scotia and Newfoundland & Labrador. EnCana operates 10 of its 16 licenses in these areas and has an average working interest of approximately 61 percent.

19

---

        EnCana is the operator of the Deep Panuke field, located offshore Nova Scotia, and has an approximate 85 percent working interest at December 31, 2006. EnCana continues to examine the potential economic viability of the Deep Panuke project. In June 2006, EnCana and the Province of Nova Scotia reached an Offshore Strategic Energy Agreement that established the framework for the potential development of Deep Panuke. Subsequently, in November 2006, EnCana filed the Development Plan Application with the Canada-Nova Scotia Offshore Petroleum Board. The filing included an Environmental Assessment Report and an application to the National Energy Board for approval of the construction and operation of an offshore pipeline.

Brazil

        EnCana has non-operated interests in 10 deep and ultra-deep water exploration blocks offshore Brazil, nine of which are operated by Petrobras, the Brazilian national oil company. EnCana's landholdings on these offshore blocks total approximately 1.7 million gross acres (0.5 million net acres) with an average working interest of 31 percent. EnCana and its partners drilled one gross exploration well in 2006 in the Campos Basin.

        The Corporation is also working with Petrobras on the development of heavy oil technology that may be used to develop Brazil's significant heavy oil reserves.

Middle East

        EnCana has a 50 percent working interest in Block 2, which encompasses most of the onshore lands in the State of Qatar and covers approximately 2.2 million gross acres (1.1 million net acres). In 2005, EnCana reached an agreement to farmout 50 percent of its working interest in the block. The farmout was approved by Qatar Petroleum in February 2006. Two gross wells are planned for the block in 2007.

        EnCana also has a 50 percent working interest in onshore Blocks 3 and 4 in the Sultanate of Oman. The blocks cover approximately 8.6 million gross acres (4.3 million net acres). Three gross wells are planned in 2007.

Greenland

        EnCana has an 87 percent working interest in two exploration blocks offshore Greenland, comprising approximately 1.7 million gross acres (1.5 million net acres). In 2007, EnCana plans to farmout a portion of its interests on both blocks.

France

        In February 2006, EnCana was granted a 100 percent interest in the Foix exploration permit, which encompasses approximately 859,000 gross acres in the onshore Aquitaine Basin in southwest France. The Corporation has plans for a multi-well exploration drilling program in 2007 to identify the potential for a natural gas resource play development.

Midstream & Marketing Division

        EnCana's divisional marketing groups are focused on enhancing the netback price of the Corporation's proprietary production. Correspondingly, the Midstream & Marketing Division coordinates the market optimization activities that include third party purchases and sales of product to provide operational flexibility for transportation commitments, product type, delivery points and customer diversification. In addition, EnCana's power assets are managed to optimize the Corporation's electricity costs, particularly in the Province of Alberta.

Natural Gas Marketing

        In 2006, approximately 89 percent of EnCana's produced natural gas sales were directly marketed by EnCana to local distribution companies, industrials, other producers and energy marketing companies. The remaining 11 percent of produced natural gas sales were marketed to aggregators who supply natural gas to markets throughout North America. Prices received by EnCana are based primarily upon prevailing index prices

20

---

for natural gas. Prices are impacted by competing fuels in such markets and by regional supply and demand for natural gas.

        EnCana mitigates the market risk associated with forecasted cash flows, by entering into various risk management contracts relating to produced natural gas. For 2007, after taking into account its risk management contracts, EnCana's gas sales price portfolio exposure consists of approximately 42 percent at an average fixed NYMEX price of approximately $8.49 per million cubic feet, approximately seven percent with an insured NYMEX strike price of approximately $6.00 per million cubic feet and approximately 51 percent unhedged. Details of these transactions are found in Note 16 to EnCana's audited consolidated financial statements for the year ended December 31, 2006.

Crude Oil Marketing

        EnCana, through its operating divisions, sells and manages the transportation of its western Canadian crude oil to markets in Canada and the U.S. (134,869 barrels per day in 2006 and 131,638 barrels per day in 2005). Crude oil sales are normally executed under spot and monthly evergreen contracts with delivery to major pipeline hubs, such as Edmonton and Hardisty, in Alberta, with EnCana arranging the intermediate transportation on the feeder pipeline systems. Sales are also made on a delivered basis using trunk pipeline systems, such as the Enbridge system, for sales to U.S. refinery destinations.

        EnCana provides North American marketing services to certain organizations on a fee for service basis. In 2006, EnCana acted as exclusive agent for Canadian Oil Sands Limited ("COS") and marketed COS' Syncrude volumes of 47,583 barrels per day (81,019 barrels per day in 2005). The COS marketing agreement terminated in the second quarter of 2006. EnCana also provides marketing services to the ADOE (45,542 barrels per day in 2006 and 48,425 barrels per day in 2005). This agency agreement ends in the second quarter of 2007.

        To help mitigate the market risk associated with forecasted cash flows, EnCana enters into various risk management contracts relating to crude oil. Details of these transactions are found in Note 16 to EnCana's audited consolidated financial statements for the year ended December 31, 2006.

Power

        EnCana is a large consumer of electricity in Alberta and uses a portfolio of physical assets, short to medium term purchases and sales and spot market purchases to manage the cost of electricity for its operating divisions in Alberta's deregulated market. The physical assets include two, 106 megawatt gas-fired power plants in southern Alberta. The Cavalier Power Station, located approximately 54 kilometres east of Calgary, is 100 percent owned and operated by EnCana. The Balzac Power Station, in which EnCana holds a 50 percent non-operated interest, is also located near Calgary. EnCana's electricity requirements in Alberta are approximately 185 megawatts and its generation capacity is approximately 159 megawatts, excluding both the electricity requirements and generation capacity of the Integrated Oilsands Division.

RESERVES AND OTHER OIL AND GAS INFORMATION

        EnCana has retained independent qualified reserves evaluators to evaluate and prepare reports on 100 percent of EnCana's natural gas, crude oil and NGLs reserves annually since its inception. In 2006, EnCana's Canadian reserves were evaluated by McDaniel & Associates Consultants Ltd. and GLJ Petroleum Consultants Ltd., and its U.S. reserves were evaluated by Netherland, Sewell & Associates, Inc. and DeGolyer and MacNaughton.

        EnCana has a Reserves Committee of independent board members which reviews the qualifications and appointment of the independent qualified reserves evaluators. The Reserves Committee also reviews the procedures for providing information to the evaluators. All booked reserves are based upon annual evaluations by the independent qualified reserves evaluators. The evaluations are conducted from the fundamental geological and engineering data.

Reserves Quantities Information

        EnCana's natural gas reserves increased approximately five percent in 2006 as a result of successful exploration and development drilling, which resulted in extensions and discoveries of 1,620 billion cubic feet. Included in the revisions and improved recovery category for changes in natural gas reserves were positive revisions in Canada and downward revisions in the U.S., resulting in total positive revisions of 213 billion cubic feet, or approximately two percent of proved natural gas reserves at the beginning of 2006. CBM Integrated accounted for the majority of the positive revisions in Canada. Downward revisions of 88 billion cubic feet in the U.S. were largely a consequence of proved undeveloped reserves being removed given planned moderation in activity levels over the next five years.

        In 2005 and 2004, natural gas reserves increased from exploration and development drilling and acquisitions.

        EnCana's crude oil and NGLs reserves were essentially unchanged at year-end 2006 in comparison to year-end 2005. Significant increases in proved reserves primarily at Christina Lake and Foster Creek were offset by the completion of the sale of EnCana's interests in Ecuador and negative revisions in Canada. The downward revision in Canada was a consequence of net reserves being reduced in light of higher calculated average royalty rates at Foster Creek stemming from an almost two fold increase in field prices relative to the prior year-end.

        In 2005, crude oil and NGLs reserves increased significantly, largely as a result of the reinstatement, due to prices at year-end 2005, of 363 million barrels that appeared as a downward revision in 2004 due to anomalously lower bitumen prices at year-end 2004. The Corporation's crude oil and NGLs reserves decreased in 2004 primarily as a result of the divestiture of non-core properties and the negative revision in Canadian bitumen reserves.

        In keeping with U.S. standards requiring that the reserves and related future net revenue be estimated under existing economic and operating conditions (i.e., prices and costs as of the date that the estimate is made), reference year-end 2006 prices were as follows: crude oil (WTI) $60.85/bbl, (Edmonton Light) C$67.58/bbl, both essentially unchanged from year-end 2005; Foster Creek field price C$35.10/bbl, an increase of 91 percent from year-end 2005; natural gas (Henry Hub) $5.64/MMbtu, a decrease of 45 percent from year-end 2005; and natural gas (AECO) C$6.07/MMbtu, a decrease of 37 percent from year-end 2005.

        The following table sets forth reserves continuity information prepared by EnCana in accordance with U.S. disclosure standards, including SFAS 69. The end of year numbers represent estimates derived from the reports of the independent qualified reserves evaluators referred to above.

Definitions:

a.

"Net" reserves are the remaining reserves of EnCana, after deduction of estimated royalties and including royalty interests.

b.

"Proved" reserves are the estimated quantities of crude oil, natural gas and NGLs which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made.

c.

"Proved Developed" reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

d.

"Proved Undeveloped" reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(2)

EnCana does not file any estimates of total net proved crude oil or natural gas reserves with any U.S. federal authority or agency other than the SEC.

(3)

Removal of the Corporation's Foster Creek proved bitumen reserves as a result of low bitumen prices on December 31, 2004.

(4)

Reinstatement, as a result of year-end 2005 prices, of the Corporation's Foster Creek proved bitumen reserves that were deducted as a revision due to bitumen price at year-end 2004.

(5)

The Corporation divested its Ecuadorian operations in 2006.

(6)

Proved crude oil and NGLs reserves at December 31, 2006 include approximately 800 million barrels of bitumen, of which 796 million barrels was attributable to the Corporation's interests in Foster Creek and Christina Lake on that date. Effective January 2, 2007, these interests were contributed to the Upstream Partnership in which the Corporation has a 50 percent interest. Accordingly, effective as at that date, the Corporation's reserves associated with those properties were reduced by 398 million barrels.

Other Disclosures About Oil and Gas Activities

        The tables in this section set forth oil and gas information prepared by EnCana in accordance with U.S. disclosure standards, including SFAS 69.

Standardized Measure of Discounted Future Net Cash Flows and Changes Therein

        In calculating the standardized measure of discounted future net cash flows, year-end constant prices and cost assumptions were applied to EnCana's annual future production from proved reserves to determine cash inflows. Future production and development costs are based on constant price assumptions and assume the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying statutory income tax rates to future pre-tax cash flows after provision for the tax cost of the oil and natural gas properties based upon existing laws and regulations. The discount was computed by application of a 10 percent discount factor to the future net cash flows. The calculation of the standardized measure of discounted future net cash flows is based upon the discounted future net cash flows prepared by EnCana's independent qualified reserves evaluators in relation to the reserves they respectively evaluated, and adjusted by EnCana to account for management's estimates of price risk management activities, asset retirement obligations and future income taxes.

        EnCana cautions that the discounted future net cash flows relating to proved oil and gas reserves are an indication of neither the fair market value of EnCana's oil and gas properties, nor the future net cash flows expected to be generated from such properties. The discounted future net cash flows do not include the fair market value of exploratory properties and probable or possible oil and gas reserves, nor is consideration given to the effect of anticipated future changes in crude oil and natural gas prices, development, asset retirement and production costs and possible changes to tax and royalty regulations. The prescribed discount rate of 10 percent may not appropriately reflect future interest rates. The computation also excludes values attributable to EnCana's Market Optimization interests.

Acquisitions, Divestitures and Capital Expenditures

        EnCana's growth in recent years has been achieved through a combination of internal growth and acquisitions. EnCana has a large inventory of internal growth opportunities and also continues to examine select acquisition opportunities to develop and expand its key resource plays. The acquisition opportunities may include corporate or asset acquisitions, and EnCana may finance any such acquisitions with debt, equity, cash generated from operations, proceeds from asset divestitures or a combination of these sources.

        The following table summarizes EnCana's net capital investment for 2006 and 2005.

Delivery Commitments

        As part of ordinary business operations, EnCana has a number of delivery commitments to provide crude oil and natural gas under existing contracts and agreements. The Corporation has sufficient reserves of natural gas and crude oil to meet these commitments. More detailed information relating to such commitments can be found in Note 18 to EnCana's audited consolidated financial statements for the year ended December 31, 2006.

GENERAL

Competitive Conditions

        All aspects of the oil and gas industry are highly competitive and EnCana actively competes with oil and natural gas and other companies, particularly in the following areas: (i) exploration for and development of new sources of oil and natural gas reserves; (ii) reserves and property acquisitions; (iii) transportation and marketing of oil, natural gas, NGLs, diluents and electricity; (iv) supply of refinery feedstock and the market for refined products (v) access to services and equipment to carry out exploration, development or operating activities; and (vi) attracting and retaining experienced industry personnel. The oil and gas industry also competes with other industries focused on providing alternative forms of energy to consumers. Competitive forces can lead to cost increases or result in an oversupply of oil and natural gas, both of which could have a negative impact on EnCana's financial results.

Environmental Protection

        EnCana's worldwide operations are subject to government laws and regulations concerning pollution, protection of the environment and the handling and transport of hazardous materials. These laws and regulations generally require EnCana to remove or remedy the effect of its activities on the environment at present and former operating sites, including dismantling production facilities and remediating damage caused by the use or release of specified substances. The Corporate Responsibility, Environment, Health and Safety Committee of EnCana's Board of Directors reviews and recommends to the Board of Directors for approval environmental policy and oversees compliance with government laws and regulations. Monitoring and reporting programs for environmental, health and safety ("EH&S") performance in day-to-day operations, as well as inspections and assessments, are designed to provide assurance that environmental and regulatory standards are met. Contingency plans are in place for a timely response to an environmental event and remediation/ reclamation programs are in place and utilized to restore the environment.

        EnCana expects to incur abandonment and site reclamation costs as existing oil and gas properties are abandoned and reclaimed. In 2006, expenditures beyond normal compliance with environmental regulations were not material. EnCana does not anticipate making material expenditures beyond normal compliance with environmental regulations in 2007. Based on EnCana's current estimate, the total anticipated undiscounted future cost of abandonment and reclamation costs to be incurred over the life of the reserves is estimated at approximately $5.3 billion.

Social and Environmental Policies

        In 2003, EnCana developed a Corporate Responsibility Policy (the "Policy") that translates its constitutional values and shared principles into policy commitments. The Policy applies to any activity undertaken by or on behalf of EnCana, anywhere in the world, associated with the finding, production, transmission and storage of the Corporation's products including decommissioning of facilities, marketing and other business and administrative functions. The Policy has specific requirements in areas related to: (i) leadership commitment, (ii) sustainable value creation, (iii) governance and business practices, (iv) human rights, (v) labour practices, (vi) environment, health and safety, (vii) stakeholder engagement, and (viii) socio-economic and community development.

        Accountability for implementation of the Policy is at the operational level within EnCana's business units. Business units have established processes to evaluate risks, and programs are implemented to minimize that risk. Results related to the commitments outlined in the Corporate Constitution are tied to the individual performance assessment process.

45

---

        With respect to human rights, the Policy states that: (i) while governments have the primary responsibility to promote and protect human rights, EnCana shares this goal and will support and respect human rights within its sphere of influence; (ii) EnCana will not take part in human rights abuse, and will not engage or be complicit in any activity that solicits or encourages human rights abuse; and (iii) in providing for the protection of company personnel and assets by public or private security forces, EnCana will promote respect for, and protection of, human rights.

        The Policy states the following with respect to the environment: (i) EnCana will safeguard the environment, and will operate in a manner consistent with recognized global industry standards in environment, health and safety; (ii) in all of its operations, EnCana will strive to make efficient use of resources, to minimize its environmental footprint, and to conserve habitat diversity and the plant and animal populations that may be affected by its operations; and (iii) EnCana will strive to reduce its emissions intensity and increase its energy efficiency.

        With respect to EnCana's relationship with the communities in which it does business, the Policy states that: (i) EnCana emphasizes collaborative, consultative and partnership approaches in its community investment and programs, recognizing that no corporation is solely responsible for changing the fundamental economic, environmental and social situation in a community or country; and (ii) through its activities, EnCana will assist in local capacity-building and develop mutually beneficial relationships, to make a positive difference in the communities and regions where it operates.

Foreign Operations

        As at December 31, 2006, 100 percent of EnCana's reserves and 100 percent of its production were located in North America, which limits EnCana's exposure to risks and uncertainties in countries considered politically and economically unstable. EnCana's operations and related assets outside North America may be adversely affected by changes in governmental policy, social instability or other political or economic developments which are not within the control of EnCana, including the expropriation of property, the cancellation or modification of contract rights and restrictions on repatriation of cash. The Corporation has undertaken to mitigate these risks where practical and considered warranted.

Reorganizations

        As discussed under "Name and Incorporation" in this annual information form, EnCana was formed through the Merger of AEC and PanCanadian on April 5, 2002. AEC remained in existence as an indirect wholly owned subsidiary of EnCana, and on January 1, 2003, AEC was amalgamated with EnCana.

        As a general matter, EnCana reorganizes its subsidiaries as required to maintain proper alignment of its businesses and facilitate acquisitions and divestitures. Between December 2005 and February 2006, the Corporation completed a restructuring of various Canadian subsidiaries in order to eliminate corporate entities that had become unnecessary.

Pre-Approval Policies and Procedures

        EnCana has adopted policies and procedures with respect to the pre-approval of audit and permitted non-audit services to be provided by PricewaterhouseCoopers LLP. The Audit Committee of the Board of Directors has established a budget for the provision of a specified list of audit and permitted non-audit services that the Audit Committee believes to be typical, recurring or otherwise likely to be provided by PricewaterhouseCoopers LLP. The budget generally covers the period between the adoption of the budget and the next meeting of the Audit Committee, but at the option of the Audit Committee it may cover a longer or shorter period. The list of services is sufficiently detailed as to the particular services to be provided to ensure that (i) the Audit Committee knows precisely what services it is being asked to pre-approve and (ii) it is not necessary for any member of management to make a judgment as to whether a proposed service fits within the pre-approved services.

        Subject to the next paragraph, the Audit Committee has delegated authority to the Chairman of the Audit Committee (or if the Chairman is unavailable, any other member of the Committee) to pre-approve the provision of permitted services by PricewaterhouseCoopers LLP which are not otherwise pre-approved by the Audit Committee, including the fees and terms of the proposed services ("Delegated Authority"). Any required determination about the Chairman's unavailability is required to be made by the good faith judgment of the applicable other member(s) of the Audit Committee after considering all facts and circumstances deemed by such member(s) to be relevant. All pre-approvals granted pursuant to Delegated Authority must be presented by the member(s) who granted the pre-approvals to the full Audit Committee at its next meeting.

        The fees payable in connection with any particular service to be provided by PricewaterhouseCoopers LLP that has been pre-approved pursuant to Delegated Authority (i) may not exceed C$200,000, in the case of pre-approvals granted by the Chairman of the Audit Committee, and (ii) may not exceed C$50,000, in the case of pre-approvals granted by any other member of the Audit Committee.

        All proposed services or the fees payable in connection with such services that have not already been pre-approved must be pre-approved by either the audit committee or pursuant to Delegated Authority. Prohibited services may not be pre-approved by the audit committee or pursuant to Delegated Authority.

External Auditor Service Fees

        The following table provides information about the fees billed to the Corporation for professional services rendered by PricewaterhouseCoopers LLP during fiscal 2006 and 2005:

($ thousands)		2006		2005
Audit Fees(1)		3,762		3,726
Audit-Related Fees(2)		401		894
Tax Fees(3)		1,215		1,021
All Other Fees(4)		34		26
Total		5,412		5,667

Notes:

(1)

Audit fees consist of fees for the audit of the Corporation's annual financial statements or services that are normally provided in connection with statutory and regulatory filings or engagements.

(2)

Audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of the audit or review of the Corporation's financial statements and are not reported as Audit Fees. During fiscal 2006 and 2005, the services provided in this category included due diligence reviews in connection with acquisitions and divestitures, research of accounting and audit-related issues and review of reserves disclosure.

(3)

Tax fees consist of fees for tax compliance services, tax advice and tax planning. During fiscal 2006 and 2005, the services provided in this category included assistance and advice in relation to the preparation of corporate income tax returns and expatriate tax services.

DESCRIPTION OF SHARE CAPITAL

        The Corporation is authorized to issue an unlimited number of Common Shares, an unlimited number of First Preferred Shares and an unlimited number of Second Preferred Shares. As of December 31, 2006 there were approximately 784 million Common Shares outstanding and no Preferred Shares outstanding.

        At the annual and special meeting of EnCana's shareholders on April 27, 2005, the Corporation's shareholders approved the subdivision of EnCana's outstanding common shares on a two-for-one basis. Each shareholder received one additional common share for each common share held on the record date for the stock split of May 12, 2005. EnCana's common shares commenced trading on a subdivided basis on May 10, 2005.

Common Shares

        The holders of the Common Shares are entitled to receive dividends if, as and when declared by the Board of Directors of the Corporation. The holders of the Common Shares are entitled to receive notice of and to attend all meetings of shareholders and are entitled to one vote per Common Share held at all such meetings. In the event of the liquidation, dissolution or winding up of the Corporation or other distribution of assets of the Corporation among its shareholders for the purpose of winding up its affairs, the holders of the Common Shares will be entitled to participate rateably in any distribution of the assets of the Corporation.

        EnCana has stock-based compensation plans that allow employees to purchase Common Shares of the Corporation. Option exercise prices approximate the market price for the Common Shares on the date the options were issued. Options granted under the plan are generally fully exercisable after three years and expire five years after the grant date. Options granted under predecessor and/or related company replacement plans expire up to 10 years from the date the options were granted.

        The Corporation has a shareholder rights plan (the "Plan") that was adopted to ensure, to the extent possible, that all shareholders of the Corporation are treated fairly in connection with any take-over bid for the Corporation. The Plan creates a right that attaches to each present and subsequently issued Common Share. Until the separation time, which typically occurs at the time of an unsolicited takeover bid, whereby a person acquires or attempts to acquire 20 percent or more of EnCana's Common Shares, the rights are not separable from the Common Shares, are not exercisable and no separate rights certificates are issued. Each right entitles the holder, other than the 20 percent acquiror, from and after the separation time and before certain expiration times, to acquire one Common Share at 50 percent of the market price at the time of exercise. The plan was reconfirmed at the 2004 annual meeting of shareholders and must be reconfirmed at every third annual meeting thereafter until it expires on July 30, 2011. It is anticipated that the Plan will be presented to shareholders for reconfirmation at the 2007 annual and special meeting of shareholders.

Preferred Shares

        Preferred Shares may be issued in one or more series. The Board of Directors may determine the designation, rights, privileges, restrictions and conditions attached to each series of Preferred Shares before the issue of such series. Holders of the Preferred Shares are not entitled to vote at any meeting of the shareholders of the Corporation, but may be entitled to vote if the Corporation fails to pay dividends on that series of Preferred Shares. The First Preferred Shares are entitled to priority over the Second Preferred Shares and the Common Shares of the Corporation with respect to the payment of dividends and the distribution of assets of the Corporation in the event of any liquidation, dissolution or winding up of the Corporation's affairs.

CREDIT RATINGS

        The following table outlines the ratings of the Corporation's debt as of December 31, 2006.

		Standard & Poor's Ratings Services ("S&P")		Moody's Investors Service ("Moody's")		Dominion Bond Rating Service ("DBRS")
Senior Unsecured/Long-Term Rating		A-		Baa2		A (low)
Commercial Paper/Short-Term Rating		A-1 (low)		P-2		R-1 (low)
Outlook		Negative		Positive		Stable

        S&P's long-term credit ratings are on a rating scale that ranges from AAA to D, which represents the range from highest to lowest quality of such securities rated. A rating of A- by S&P is within the third highest of ten categories and indicates that the obligor has strong capacity to meet its financial commitments but is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligors in higher rated categories. The addition of a plus (+) or minus (-) designation after a rating indicates the relative standing within a particular rating category. The negative outlook status implies that the rating could remain the same or be lowered. S&P's Canadian commercial paper ratings scale ranges from A-1 (high) to D, representing the range from highest to lowest quality. A-1 (low) is the third highest of eight categories and indicates that the obligor has satisfactory capacity to meet its financial commitments.

        Moody's long-term credit ratings are on a rating scale that ranges from Aaa to C, which represents the range from highest to lowest quality of such securities rated. A rating of Baa2 by Moody's is within the fourth highest of nine categories and is assigned to debt securities which are considered medium-grade obligations (i.e., they are subject to moderate credit risk). Such debt securities may possess certain speculative characteristics. The addition of a 1, 2 or 3 modifier after a rating indicates the relative standing within a particular rating category. The modifier 1 indicates that the issue ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category. The addition a ratings outlook of "Positive (POS)", "Negative (NEG)" or "Stable (STA)"is an opinion regarding the likely direction of a rating over the medium term. Moody's short-term ratings are on a scale ranging from P-1 (highest quality) to NP (lowest quality). P-2 is the second highest of four categories and indicates that the issuer has a strong ability to repay short-term debt obligations.

        DBRS' long-term credit ratings are on a rating scale that ranges from AAA to D, which represents the range from highest to lowest quality of such securities rated. A rating of A (low) by DBRS is within the third highest of ten categories and is assigned to debt securities considered to be of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than that of AA rated entities. While a respectable rating, entities in the A category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated securities. The assignment of a "(high)" or "(low)" modifier within each rating category indicates relative standing within such category. DBRS' short-term ratings are on a scale ranging from R-1 (high) to D, representing the range from highest to lowest quality. R-1 (low) is the third highest of ten categories and indicates that the short-term debt is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favourable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors that exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

        Credit ratings are intended to provide investors with an independent measure of credit quality of any issue of securities. The credit ratings assigned by the rating agencies are not recommendations to purchase, hold or sell the securities inasmuch as such ratings do not comment as to market price or suitability for a particular investor. Any rating may not remain in effect for any given period of time or may be revised or withdrawn entirely by a rating agency in the future if in its judgment circumstances so warrant.

        In November 2006, EnCana received approval from the TSX to renew its normal course issuer bid. Under the renewed program, EnCana is entitled to purchase up to 10 percent of its outstanding common shares. Purchases may be made through the facilities of the TSX and the NYSE, in accordance with the policies and rules of each exchange.

        During January 2007, EnCana purchased 10.8 million shares under the program for approximately $494 million.

        In 2006, EnCana purchased 85.6 million shares under the program for an average price of $49.26 for approximately $4.2 billion.

DIVIDENDS

        The declaration of dividends is at the discretion of the Board of Directors and is approved quarterly. In 2004, cash dividends were paid to common shareholders at a rate of $0.20 per share annually ($0.05 per share quarterly). In the second quarter of 2005, EnCana increased its dividend by 50 percent to $0.30 per share annually ($0.075 per share quarterly). In the second quarter of 2006, EnCana increased its dividend by 33 percent to $0.40 per share ($0.10 per share quarterly). EnCana's Board of Directors has declared a dividend of $0.20 per share payable on March 30, 2007 to common shareholders of record on March 15, 2007, a 100 percent increase over the previous dividend. All of the figures in this section have been adjusted to reflect the May 2005 share split.

LEGAL PROCEEDINGS

        The Corporation is involved in various claims and litigation arising in the normal course of business. While the outcome of these matters is uncertain and there can be no assurance that such matters will be resolved in EnCana's favour, the Corporation does not currently believe that the outcome of any pending or threatened proceedings related to these or other matters, or the amounts which the Corporation may be required to pay by reason thereof, would have a material adverse impact on its financial position, results of operations or liquidity.

        For information on legal proceedings related to EnCana's discontinued merchant energy trading operations refer to "Risk Factors" in this annual information form.

RISK FACTORS

        If any event arising from the risk factors set forth below occurs, EnCana's business, prospects, financial condition, results of operation or cash flows could be materially adversely affected.

A substantial or extended decline in crude oil and natural gas prices could have a material adverse effect on EnCana.

        EnCana's financial performance and condition are substantially dependent on the prevailing prices of crude oil and natural gas. Fluctuations in crude oil or natural gas prices could have an adverse effect on the Corporation's operations and financial condition and the value and amount of its proved reserves. Prices for crude oil and natural gas fluctuate in response to changes in the supply of and demand for crude oil and natural gas, market uncertainty and a variety of additional factors beyond the Corporation's control. Crude oil prices are determined by international supply and demand. Factors which affect crude oil prices include the actions of the Organization of Petroleum Exporting Countries, world economic conditions, government regulation, political stability in the Middle East and elsewhere, the foreign supply of crude oil, the price of foreign imports, the availability of alternate fuel sources and weather conditions. Natural gas prices realized by EnCana are affected primarily by North American supply and demand, weather conditions and by prices of alternate sources of energy. Any substantial or extended decline in the prices of crude oil and natural gas could result in a delay or cancellation of existing or future drilling, development or construction programs or curtailment in production at some properties or could result in unutilized long-term transportation commitments, all of which could have an adverse effect on the Corporation's revenues, profitability and cash flows.

        The market prices for heavy oil are lower than the established market indices for light and medium grades of oil, due principally to diluent prices and the higher transportation and refining costs associated with heavy oil. Also, the market for heavy oil is more limited than for light and medium grades, making it more susceptible to supply and demand fundamentals. Future price differentials are uncertain and any increase in the heavy oil differentials could have a material adverse effect on EnCana's business.

        EnCana conducts an annual assessment of the carrying value of its assets in accordance with Canadian GAAP. If crude oil and natural gas prices decline, the carrying value of EnCana's assets could be subject to financial downward revisions, and the Corporation's earnings could be adversely affected.

If EnCana fails to acquire or find additional crude oil and natural gas reserves, the Corporation's reserves and production will decline materially from their current levels.

        EnCana's future crude oil and natural gas reserves and production, and therefore its cash flows, are highly dependent upon its success in exploiting its current reserves base and acquiring, discovering or developing additional reserves. Without reserves additions through exploration, acquisition or development activities, the Corporation's reserves and production will decline over time as reserves are depleted. The business of exploring for, developing or acquiring reserves is capital intensive. To the extent cash flows from operations are insufficient and external sources of capital become limited, EnCana's ability to make the necessary capital investments to maintain and expand its crude oil and natural gas reserves will be impaired. In addition, there can be no guarantee that EnCana will be able to find and develop or acquire additional reserves to replace production at acceptable costs.

EnCana's crude oil and natural gas reserves data and future net revenue estimates are uncertain.

        There are numerous uncertainties inherent in estimating quantities of crude oil and natural gas reserves, including many factors beyond the Corporation's control. The reserves data in this annual information form represents estimates only. In general, estimates of economically recoverable crude oil and natural gas reserves and the future net cash flows therefrom are based upon a number of variable factors and assumptions, such as product prices, future operating and capital costs, historical production from the properties and the assumed effects of regulation by governmental agencies, all of which may vary considerably from actual results. All such estimates are to some degree uncertain, and classifications of reserves are only attempts to define the degree of uncertainty involved. For those reasons, estimates of the economically recoverable crude oil and natural gas

56

---

reserves attributable to any particular group of properties, classification of such reserves based on risk of recovery and estimates of future net revenues expected therefrom, prepared by different engineers or by the same engineers at different times, may vary substantially. EnCana's actual production, revenues, taxes and development and operating expenditures with respect to its reserves may vary from such estimates, and such variances could be material.

        Estimates with respect to reserves that may be developed and produced in the future are often based upon volumetric calculations and upon analogy to similar types of reserves, rather than upon actual production history. Estimates based on these methods generally are less reliable than those based on actual production history. Subsequent evaluation of the same reserves based upon production history will result in variations, which may be material, in the estimated reserves.

EnCana's hedging activities could result in realized and unrealized losses.

        The nature of the Corporation's operations results in exposure to fluctuations in commodity prices and interest rates. The Corporation monitors its exposure to such fluctuations and, where the Corporation deems it appropriate, utilizes derivative financial instruments and physical delivery contracts to mitigate the potential impact of declines in crude oil and natural gas prices and changes in interest rates. Under Canadian GAAP, derivative instruments that do not qualify as hedges, or are not designated as hedges, are marked-to-market with changes in fair value recognized in current period net earnings. The utilization of derivative financial instruments may therefore introduce significant volatility into the Corporation's reported net earnings.

        The terms of the Corporation's various hedging agreements may limit the benefit to the Corporation of commodity price increases or changes in interest rates. The Corporation may also suffer financial loss because of hedging arrangements if:

•

the Corporation is unable to produce oil or natural gas to fulfill delivery obligations;



•

the Corporation is required to pay royalties based on market or reference prices that are higher than hedged prices; or



•

counterparties to the Corporation's hedging agreements are unable to fulfill their obligations under the hedging agreements.

EnCana's ability to complete projects is dependent on factors outside of its control.

        The Corporation undertakes a variety of projects including exploration and development projects and the construction or expansion of facilities, refineries and pipelines. Project delays may delay expected revenues and project cost overruns could make projects uneconomic. The Corporation's ability to complete projects depends upon numerous factors beyond the Corporation's control. These factors include:

•

the availability of processing capacity;



•

the availability and proximity of pipeline capacity;



•

the availability of drilling and other equipment;



•

the availability of diluents to transport crude oil;



•

the ability to access lands;



•

weather;



•

unexpected cost increases;



•

accidents;



•

general business and market conditions;



•

the availability of skilled labour; and



•

environmental and regulatory matters.

57

---

        All of EnCana's operations are subject to regulation and intervention by governments that can affect or prohibit the drilling, completion and tie-in of wells, production, the construction or expansion of facilities and the operation and abandonment of fields. Contract rights can be cancelled or expropriated. Changes to government regulation could impact the Corporation's existing and planned projects.

The Corporation's business is subject to environmental legislation in all jurisdictions in which it operates and any changes in such legislation could negatively affect its results of operations.

        All phases of the crude oil, natural gas and refining businesses are subject to environmental regulation pursuant to a variety of Canadian, U.S. and other federal, provincial, territorial, state and municipal laws and regulations (collectively, "environmental legislation").

        Environmental legislation imposes, among other things, restrictions, liabilities and obligations in connection with the generation, handling, use, storage, transportation, treatment and disposal of hazardous substances and waste and in connection with spills, releases and emissions of various substances to the environment. It also imposes restrictions, liabilities and obligations in connection with the management of fresh or potable water sources that are being used, or whose use is contemplated, in connection with oil and gas operations. Environmental legislation also requires that wells, facility sites and other properties associated with EnCana's operations be operated, maintained, abandoned and reclaimed to the satisfaction of applicable regulatory authorities. In addition, certain types of operations, including exploration and development projects and changes to certain existing projects, may require the submission and approval of environmental impact assessments or permit applications. Compliance with environmental legislation can require significant expenditures, including expenditures for clean up costs and damages arising out of contaminated properties and failure to comply with environmental legislation may result in the imposition of fines and penalties. Although it is not expected that the costs of complying with environmental legislation will have a material adverse effect on EnCana's financial condition or results of operations, no assurance can be made that the costs of complying with environmental legislation in the future will not have such an effect.

        The Canadian Federal Government has announced its intention to regulate greenhouse gases ("GHG") and other air pollutants. The Government is currently developing a framework that outlines its clean air and climate change action plan, including a target to reduce GHG emissions by 45 percent to 65 percent by 2050 and a commitment to regulate industry on an emissions intensity basis in the short-term. Currently there are few technical details regarding the implementation of the Government's plan to regulate industrial GHG emissions, but the Government has made a commitment to work with industry to develop the specifics.

        As this federal program is under development, EnCana is unable to predict the total impact of the potential regulations upon its business. Therefore, it is possible that the Corporation could face increases in operating costs in order to comply with GHG emissions legislation. However, EnCana in cooperation with the Canadian Association of Petroleum Producers will continue to work with the Government to develop an approach to deal with climate change issues that protects the industry's competitiveness, limits the cost and administrative burden of compliance and supports continued investment in the sector.

        EnCana will continue its current activities to reduce emissions intensity and improve energy efficiency. The Corporation's efforts with respect to emissions management are founded on the following key elements:

•

significant weighting in natural gas;



•

recognition as an industry leader in CO₂ sequestration;



•

focus on the development of technology to reduce GHG emissions;



•

involvement in the creation of industry best practices; and



•

industry leading oilsands steam to oil ratio, which translates directly into a lower emissions intensity.

EnCana's operations are subject to the risk of business interruption and casualty losses.

        The Corporation's business is subject to all of the operating risks normally associated with the exploration for, development of and production of crude oil and natural gas and the operation of midstream and refining

58

---

facilities. These risks include blowouts, explosions, fire, gaseous leaks, migration of harmful substances and crude oil spills, any of which could cause personal injury, result in damage to, or destruction of, crude oil and natural gas wells or formations or production facilities and other property, equipment and the environment, as well as interrupt operations. In addition, all of EnCana's operations will be subject to all of the risks normally incident to the transportation, processing, storing, refining and marketing of crude oil, natural gas and other related products, drilling and completion of crude oil and natural gas wells, and the operation and development of crude oil and natural gas properties, including encountering unexpected formations or pressures, premature declines of reservoir pressure or productivity, blowouts, equipment failures and other accidents, sour gas releases, uncontrollable flows of crude oil, natural gas or well fluids, adverse weather conditions, pollution and other environmental risks.

        The occurrence of a significant event against which EnCana is not fully insured could have a material adverse effect on the Corporation's financial position.

Fluctuations in exchange rates could affect expenses or result in realized and unrealized losses.

        Worldwide prices for crude oil, natural gas and refined products are set in U.S. dollars. However, many of the Corporation's expenses outside of the U.S. are denominated in Canadian dollars. Fluctuations in the exchange rate between the U.S. dollar and the Canadian dollar could impact the Corporation's expenses and have an adverse effect on the Corporation's financial performance and condition.

        In addition, the Corporation has significant U.S. dollar denominated long-term debt. Fluctuations in the exchange rate between the U.S. dollar and the Canadian dollar could result in realized and unrealized losses on U.S. dollar denominated long-term debt.

EnCana does not operate all of its properties and assets.

        Other companies operate a portion of the assets in which EnCana has interests. EnCana will have limited ability to exercise influence over operations of these assets or their associated costs. EnCana's dependence on the operator and other working interest owners for these properties and assets, and its limited ability to influence operations and associated costs could materially adversely affect the Corporation's financial performance. The success and timing of EnCana's activities on assets operated by others therefore will depend upon a number of factors that are outside of the Corporation's control, including:

•

timing and amount of capital expenditures;



•

timing and amount of operating and maintenance expenditures;



•

the operator's expertise and financial resources;



•

approval of other participants;



•

selection of technology; and



•

risk management practices.

        All of the Corporation's downstream operations are operated by ConocoPhillips. The success of the Corporation's downstream operations is dependant on the ability of ConocoPhillips to successfully operate this business.

The volatility of downstream margins will have an impact on EnCana's results.

        EnCana's downstream operations are sensitive to margins for refined products. Margin volatility is impacted by numerous conditions including: market competitiveness, the cost of crude oil, fluctuations in the supply and demand for refined products and weather. It is expected that all of these and other factors will continue to impact downstream margins for the foreseeable future. As a result, it can be reasonably expected that downstream results will fluctuate over time and from period to period.

59

---

The Corporation's foreign operations will expose it to risks from abroad which could negatively affect its results of operations.

        Some of EnCana's operations and related assets are located in countries outside North America, some of which may be considered to be politically and economically unstable. Exploration or development activities in such countries may require protracted negotiations with host governments, national oil companies and third parties and are frequently subject to economic and political considerations, such as taxation, nationalization, expropriation, inflation, currency fluctuations, increased regulation and approval requirements, governmental regulation and the risk of actions by terrorist or insurgent groups, any of which could adversely affect the economics of exploration or development projects.

EnCana is exposed to risks associated with the use of current technology, and the pursuit of new technology, which could negatively affect its results of operations.

        Current SAGD technologies for in-situ recovery of heavy oil and bitumen are energy intensive, requiring significant consumption of natural gas and other fuels in the production of steam that is used in the recovery process. The amount of steam required in the production process can also vary and affect costs. The performance of the reservoir can also affect the timing and levels of production using this technology. A large increase in recovery costs could cause certain projects that rely on SAGD technology to become uneconomical, which could have a negative effect on EnCana's results of operations.

        There are risks associated with growth and other capital projects that rely largely or partly on new technologies and the incorporation of such technologies into new or existing operations. The success of projects incorporating new technologies cannot be assured.

EnCana may be adversely affected by legal proceedings related to its discontinued merchant energy trading operations.

        During the period between 2003 and 2005, EnCana and its indirect wholly owned U.S. marketing subsidiary, WD Energy Services Inc. ("WD"), along with other energy companies, were named as defendants in several lawsuits, some of which were class action lawsuits, relating to sales of natural gas from 1999 to 2002. The lawsuits allege that the defendants engaged in a conspiracy with unnamed competitors in the natural gas markets in California in violation of U.S. and California anti-trust and unfair competition laws.

        Without admitting any liability in the lawsuits, WD agreed to settle all of the class action lawsuits in both state and federal court, for payments of $20.5 million and $2.4 million, respectively. Court approval of the federal court class action settlement of $2.4 million is pending, court approval having been granted in the state court action. Also, as previously disclosed, without admitting any liability whatsoever, WD concluded settlements with the U.S. Commodity Futures Trading Commission ("CFTC") and of a previously disclosed consolidated class action lawsuit in the United States District Court in New York for $8.2 million.

        The remaining lawsuits were commenced by individual plaintiffs, one of which is E. & J. Gallo Winery ("Gallo"). The Gallo lawsuit claims damages in excess of $30 million. The other remaining lawsuits do not specify the precise amount of damages claimed. California law allows for the possibility that the amount of damages assessed could be tripled.

        EnCana intends to vigorously defend against any claims of liability alleged in the remaining lawsuits; however, the Corporation cannot predict the outcome of these proceedings or the commencement or outcome of any future proceedings against EnCana or whether any such proceeding would lead to monetary damages which could have a material adverse effect on the Corporation's financial position, or whether there will be other proceedings arising out of these allegations.

For greater certainty, directors' fees and fixed amounts of compensation under a retirement plan (including deferred compensation) for prior service with the Corporation that are not contingent on continued service should be the only compensation an audit committee member receives from the Corporation.

        At least one member shall have experience in the oil and gas industry.

        Committee members shall not simultaneously serve on the audit committees of more than two other public companies, unless the Board first determines that such simultaneous service will not impair the ability of the relevant members to effectively serve on the Committee, and required public disclosure is made.

        The non-executive Board Chairman shall be a non-voting member of the Committee.

Appointment of Members

        Committee members shall be appointed at a meeting of the Board, effective after the election of directors at the annual meeting of shareholders, provided that any member may be removed or replaced at any time by the Board and shall, in any event, cease to be a member of the Committee upon ceasing to be a member of the Board.

        The Nominating and Corporate Governance Committee will recommend for approval to the Board an unrelated Director to act as Chairman of the Committee. The Board shall appoint the Chairman of the Committee.

        If the Chairman of the Committee is unavailable or unable to attend a meeting of the Committee, the Chair shall ask another member to chair the meeting, failing which a member of the Committee present at the meeting shall be chosen to preside over the meeting by a majority of the members of the Committee present at such meeting.

        The Chairman of the Committee presiding at any meeting of the Committee shall not have a casting vote.

        The items pertaining to the Chairman in this section should be read in conjunction with the Committee Chair section of the Chair of the Board of Directors and Committee Chair General Guidelines.

        Where a vacancy occurs at any time in the membership of the Committee, it may be filled by the Board.

        The Corporate Secretary or one of the Assistant Corporate Secretaries of the Corporation or such other person as the Corporate Secretary of the Corporation shall designate from time to time shall be the Secretary of the Committee and shall keep minutes of the meetings of the Committee.

        The Committee shall meet at least quarterly. The Chairman of the Committee may call additional meetings as required. In addition, a meeting may be called by the non-executive Board Chairman, the President & Chief Executive Officer, or any member of the Committee or by the external auditors.

        The Committee shall have the right to determine who shall, and who shall not, be present at any time during a meeting of the Committee.

        Directors, who are not members of the Committee, may attend Committee meetings, on an ad hoc basis, upon prior consultation and approval by the Committee Chairman or by a majority of the members of the Committee.

        The Committee may, by specific invitation, have other resource persons in attendance.

        The President & Chief Executive Officer, the Executive Vice-President & Chief Financial Officer, the Comptroller and the head of internal audit are expected to be available to attend the Committee's meetings or portions thereof.

Notice of Meeting

        Notice of the time and place of each Committee meeting may be given orally, or in writing, or by facsimile, or by electronic means to each member of the Committee at least 48 hours prior to the time fixed for such meeting. Notice of each meeting shall also be given to the external auditors of the Corporation.

        A member and the external auditors may, in any manner, waive notice of the Committee meeting. Attendance of a member at a meeting shall constitute waiver of notice of the meeting except where a member attends a meeting for the express purpose of objecting to the transaction of any business on the grounds that the meeting was not lawfully called.

Quorum

        A majority of Committee members, present in person, by video conference, by telephone, or by a combination thereof, shall constitute a quorum. In addition, if an ex officio, non-voting member's presence is required to attain a quorum of the Committee, then the said member shall be allowed to cast a vote at the meeting.

Minutes

        Minutes of each Committee meeting should be succinct yet comprehensive in describing substantive issues discussed by the Committee. However, they should clearly identify those items of responsibilities scheduled by the Committee for the meeting that have been discharged by the Committee and those items of responsibilities that are outstanding.

        Minutes of Committee meetings shall be sent to all Committee members and to the external auditors.

        The full Board of Directors shall be kept informed of the Committee's activities by a report following each Committee meeting.
