ADVISORY REGARDING RESERVES DATA AND OTHER OIL AND GAS INFORMATION – EnCana's disclosure of reserves data and other oil and gas information is made in reliance on an exemption granted to EnCana by Canadian securities regulatory authorities, which permits it to provide such disclosure in accordance with U.S. disclosure requirements. The information provided by EnCana may differ from the corresponding information prepared in accordance with Canadian disclosure standards under National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities (NI 51-101). EnCana’s reserves quantities represent net proved reserves calculated using the standards contained in Regulation S-X of the U.S. Securities and Exchange Commission. Further information about the differences between the U.S. requirements and the NI 51-101 requirements is set forth under the heading "Note Regarding Reserves Data and Other Oil and Gas Information" on page 2 in EnCana's Annual Information Form, which is incorporated herein by reference.

In the filed documents referred to in this news release, certain crude oil and NGLs volumes have been converted to cubic feet equivalent (cfe) 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. BOE and cfe 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.

ADVISORY REGARDING FORWARD-LOOKING STATEMENTS – In the interests of providing EnCana shareholders and potential investors with information regarding EnCana and the proposed transaction described above in this news release, including management’s assessment of future plans and operations relating to EnCana and Cenovus, EnCana has included in this news release certain statements and information that are forward-looking statements or information within the meaning of applicable securities legislation, and which are collectively referred to herein as “forward-looking statements.” The forward-looking statements in this news release include, but are not limited to, statements with respect to: the proposed Plan of Arrangement transaction; and the expected date for the shareholders’ meeting and completing the transaction.

Readers are cautioned not to place undue reliance on forward-looking statements, as there can be no assurance that the future circumstances, outcomes or results anticipated in or implied by such forward-looking statements will occur or that plans, intentions or expectations upon which the forward-looking statements are based will occur. By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties, both general and specific, that contribute to the possibility that circumstances, events or outcomes anticipated or implied by forward-looking statements will not occur, which may cause the actual performance and financial results in future periods to differ materially from the performance or results anticipated or implied by any such forward-looking statements. These risks and uncertainties include, among other things: risks associated with the ability to obtain any necessary approvals, waivers, consents, court orders and other requirements necessary or desirable to permit or facilitate the proposed transaction (including, regulatory and shareholder approvals); the risk that any applicable conditions of the proposed transaction may not be satisfied; volatility of and assumptions regarding oil and gas prices; assumptions contained in or relevant to the company’s current corporate guidance; fluctuations in currency and interest rates; product supply and demand; market competition; risks inherent in marketing operations (including credit risks); imprecision of reserves estimates and estimates of recoverable quantities of oil, bitumen, natural gas and liquids from resource plays and other sources not currently classified as proved reserves; the ability to successfully manage and operate the integrated North American oil business with ConocoPhillips; 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 and the application thereof to the business of EnCana and Cenovus; the ability to replace and expand oil and gas reserves; the ability to generate sufficient cash flow from operations to meet current and future obligations; the ability to access external sources of debt and equity capital; the timing and the costs of well and pipeline construction; the ability to secure adequate product transportation; changes in royalty, tax, environmental and other laws or regulations or the interpretations of such laws or regulations; applicable political and economic conditions; the risk of war, hostilities, civil insurrection, political instability and terrorist threats; risks associated with existing and potential future lawsuits and regulatory actions; and other risks and uncertainties described from time to time in the reports and filings made with securities regulatory authorities by EnCana. 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. Readers are cautioned that the foregoing list of important factors is not exhaustive.

Assumptions relating to forward-looking statements generally include EnCana’s current expectations and projections made by the company in light of, and generally consistent with, its historical experience and its perception of historical trends, as well as expectations regarding rates of advancement and innovation, generally consistent with and informed by its past experience, all of which are subject to the risk factors identified elsewhere in this document.
