Forward-Looking Information

This News Release contains forward-looking statements or information (collectively referred to herein as "forward-looking statements") relating to "reserves" 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 quantities predicted or estimated and that the reserves can be profitably produced in the future.

The forward-looking statements contained in this News Release are based on Anterra management's current beliefs as well as assumptions made by, and information currently available to, Anterra management concerning anticipated business conditions.

Forward-looking statements are not guarantees of future performance and the reader should not place undue reliance on these forward-looking statements as there can be no assurances that the assumptions, plans, initiatives or expectations upon which they are based will occur. In addition, the forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by forward-looking statements. Such factors include, among others: general economic and business conditions; the price of and demand for oil and natural gas and their effect on the economics of oil and gas exploration; actions by governmental authorities; and, changes in government regulations and the expenditures required to comply with them (including, but not limited to, the changes in taxes or the royalty or other share of production taken by governmental authorities). Should one or more of these risks or uncertainties materialize, or should any of the Company's assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements. Readers are cautioned that the foregoing list of risks, uncertainties and other factors is not exhaustive. Unpredictable or unknown factors not discussed could also have material adverse effects on forward-looking statements. The impact of any one factor on a particular forward-looking statement is not determinable with certainty as such factors are dependent on other factors, and the Company's course of action would depend on its assessment of the future considering all information then available.

Except as required by law, the Company assumes no obligation to update forward-looking statements should circumstances or management's estimates or opinions change.

BOE Conversion

Certain natural gas volumes have been converted to barrels of oil equivalent ("boe") using six thousand cubic feet ("mcf") of gas equal to one barrel ("bbl") of oil unless otherwise stated. This conversion ratio is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Such disclosure of boes may be misleading, particularly if used in isolation.
