Exhibit 99.1

NYSE: HNR www.harvestnr.com PROXY DISCUSSION December 2006

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 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; completing the conversion of Venezuelan assets to a mixed company and relationship with the majority owner; timing and extent of changes in commodity prices for oil and gas; political, contractual, economic and operating risks, particularly those 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. Cautionary note to investors - The United States Securities and Exchange Commission (SEC) permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. From time to time, Harvest may use certain terms such as resource potential, probable reserves, possible reserves, non-proved reserves or other descriptions of volumes of reserves that SEC guidelines may prohibit Harvest from including in filings with the SEC. 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 2005 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 .

BOARD CONSIDERATIONS "FOR" RECOMMENDATIONS Harvest's share of unrisked reserves and exposure to exploration upside is greater in Petrodelta compared with the existing OSA Petrodelta will deliver oil to PDVSA at market based prices equal to about 70% of WTI instead of the service fee received under the OSA of about 47% of WTI The term is extended to 2026 compared with a 2012 OSA expiration date There will be an economic adjustment between the parties as if the conversion had been completed April 1, 2006 The Conversion Contract and the Charter and By-Laws provide some minority holder protections The Board also considered risks and other factors as described in the Proxy Statement
