2. Disclaimer This presentation uses the terms “potential petroleum quantities”, “prospective resources” and “contingent resources” to describe those quantities of petroleum that are potentially recoverable from accumulations yet to be discovered. Because of the uncertainty of commerciality and lack of sufficient exploration drilling, and the lack of identified prospects, leads, or future development and exploration projects, the potential petroleum quantities estimated herein cannot be classified as prospective resources, contingent resources or reserves, and the prospective resources and contingent resources cannot be classified as reserves. Investors are advised that the U.S. Securities and Exchange Commission (SEC) and other international securities regulators do not recognize potential petroleum quantities and prospective and contingent resources. There is no certainty that any portion of the potential petroleum quantities or prospective resources will be discovered and, if discovered, whether they could be developed economically. Therefore, investors are cautioned not to assume that all or any part of OGX’s potential petroleum quantities or prospective resources exist, or that they can be developed economically. Accordingly, information concerning potential petroleum quantities and prospective and contingent resources contained in this presentation are not comparable to information permitted to be made public by U.S. or other international companies subject to SEC reporting and disclosure requirements, especially Regulation S-K under the Securities Act. Certain of the information and conclusions set forth herein are based on projections. These projections were prepared for the limited purpose of analyzing the potential risks and benefits of an investment in the securities by illustrating under certain limited assumptions projected capital and operating expenditures, installed production capacity, expected production, and number of wells drilled. In addition, because of the subjective judgments and inherent uncertainties of projections and because the projections are based on a number of assumptions, which are subject to significant uncertainties and contingencies that are beyond the control of OGX, there can be no assurance that the projections or conclusions derived therefrom will be realized. Under no circumstances should the projections set forth herein be regarded as a representation, warranty or prediction that OGX will achieve or is likely to achieve any particular future result. There can be no assurance that OGX’s future results or projections will not vary significantly from those set forth herein. Accordingly, investors may lose all of their investment to the extent the projections or conclusions included herein are not ultimately realized. This presentation also contains forward-looking statements, which may be identified by such words as "may", "plans", "expects", "believes" and similar expressions, or by their context. These statements are made on the basis of current knowledge and, by their nature, involve numerous assumptions and uncertainties.
