This press release contains "forward-looking information" which may include, but is not limited to, statements with respect to our operations. Such forward looking statements reflect our current views with respect to future events and are subject to certain risks, uncertainties and assumptions, including, the risks and uncertainties outlined under the section titles "Risk Factors and Uncertainties" in our prospectus (available at www.sedar.com). Should one or more of these risks materialise, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. Additional information in respect of the Kyzyloi shallow gas field and Akkulka area (also referred to as the Akkulka Block), including location, area, geologic age and lithology, depth, estimated costs and gas marketing information, appears in Tethys' prospectus dated June 18, 2007. Barrels of oil equivalent ("BOEs") may be misleading, particularly if used in isolation. A BOE conversion ratio of 6,000 cubic feet of gas to 1 barrel of oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
