Forward Looking Statements Forward Looking Statements NYSE: HNR www.harvestnr.com 1 Cautionary Statements: Certain statements in this presentation are forward-looking and are based upon Harvest’s current belief as to the outcome and timing of future events. All statements other than statements of historical facts including planned capital expenditures, increases in oil and gas production, Harvest’s outlook on oil and gas prices, estimates of oil and gas reserves, business strategy and other plans, estimates, projections, and objectives for future operations, are forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Important factors that could cause actual results to differ materially from those in the forward-looking statements herein include Harvest’s concentration of assets in Venezuela; timing and extent of changes in commodity prices for oil and gas; political and economic risks associated with international operations; and other risk factors as described in Harvest’s Annual Report on Form 10-K and other public filings. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, Harvest’s actual results and plans could differ materially from those expressed in the forward-looking statements. Harvest undertakes no obligation to publicly update or revise any forward-looking statements. Harvest may use certain terms such as resource base, contingent resources, prospective resources, probable reserves, possible reserves, non-proved reserves or other descriptions of volumes of reserves. These estimates are by their nature more speculative than estimates of proved reserves and accordingly, are subject to substantially greater risk of being actually realized by the Company. Investors are urged to consider closely the disclosure in our 2011 Annual Report on Form 10-K and other public filings available from Harvest at 1177 Enclave Parkway, Houston, Texas, 77077 or from the SEC’s website at www.sec.gov. Contingent resources are resources that are potentially recoverable but not yet considered mature enough for commercial development due to technological or business hurdles. Prospective resources are those quantities of hydrocarbons which are estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. They indicate exploration opportunities and development potential in the event a discovery is made and should not be construed as contingent resources or reserves. The contingent and prospective resources included in this presentation were internally developed by Harvest Natural Resources. |
