NOTES TO CONSOLIDATED FINANCIAL STATEMENTS ~~FIRST QUARTER~~

First Quarter 2006 and 2005 ~~AND 2004 (UNAUDITED) NOTE~~(unaudited)

Note 1 ~~- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES INTERIM REPORTING~~— Organization and Summary of Significant Accounting Policies

Interim Reporting

In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals only) necessary to present fairly the financial position as of March 31, ~~2005,~~2006, and the results of operations and cash flows for the first quarter ~~2005~~2006 and ~~2004.~~2005. The unaudited consolidated financial statements are presented in accordance with the requirements of Form 10-Q and do not include all disclosures normally required by accounting principles generally accepted in the United States of America. Reference should be made to our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended ~~2004,~~2005, which include certain definitions and a summary of significant accounting policies and should be read in conjunction with this Quarterly Report on Form 10-Q. The results of operations for ~~any~~the interim period are subject to the receipt of the first quarter 2006 payment under the Operating Service Agreement (“OSA”) which is due by the end of May. In addition, the results for this quarter are not necessarily indicative of the results of operations for the entire ~~year. ORGANIZATION~~year due to the uncertainty of the situation in Venezuela, including the possible conversion of the OSA to a mixed company (the “Mixed Company”) as described in Note 6.

Organization

Harvest Natural Resources, Inc. is engaged in the exploration, development, production and management of oil and natural gas properties. We conduct our business principally in Venezuela through our 80 percent owned subsidiary Harvest-Vinccler, C.A. ("(“Harvest ~~Vinccler"~~Vinccler”). ~~PRINCIPLES OF CONSOLIDATION~~

Principles of Consolidation

The consolidated financial statements include the accounts of all wholly-owned and majority-owned subsidiaries. All intercompany profits, transactions and balances have been eliminated. ~~MINORITY INTERESTS~~

Reporting and Functional Currency

The U.S. Dollar is our functional and reporting currency.

Revenue Recognition

Oil and natural gas revenue is accrued monthly based on production and delivery. Each quarter, Harvest Vinccler invoices PDVSA Petroleo S.A., an affiliate of Petroleos de Venezuela S.A. (“PDVSA”), based on barrels of oil accepted by PDVSA during the quarter, using quarterly adjusted U.S. Dollar contract service fees per barrel. The related OSA with PDVSA provides for Harvest Vinccler to receive an operating fee for each barrel of crude oil delivered and the right to receive a capital recovery fee for certain of its capital expenditures, provided that such operating fee and capital recovery fee cannot exceed the maximum total fee per barrel set forth in the agreement. In August 2005, Harvest Vinccler and PDVSA executed a Transitory Agreement (the “Transitory Agreement”) which provides that the maximum total fee per barrel paid under the OSA could not exceed 66.67 percent of the total value of the crude oil as determined under an Annex to the Transitory Agreement. This limitation was applied retroactively to January 1, 2005 and approximates 47 percent of West Texas Intermediate (“WTI”). The operating fee is subject to quarterly adjustments to reflect changes in the special energy index of the U.S. Consumer Price Index. Each quarter, Harvest Vinccler also invoices PDVSA for natural gas sales based on a fixed price of $1.03 per Mcf. In addition, Harvest Vinccler agreed to sell to PDVSA 4.5 million barrels of oil stipulated as additional volumes resulting from the natural gas production (“Incremental Crude Oil”). A portion of the Incremental Crude Oil is invoiced to PDVSA quarterly at a fixed price of $7.00 per Bbl. The invoices are prepared and submitted to PDVSA by the end of the first month following the end of each calendar quarter, and payment is due from PDVSA by the end of the second month following the end of each calendar quarter. Harvest Vinccler invoiced PDVSA for the first quarter 2006 delivery of its crude oil and natural gas in accordance with the Transitory Agreement. However, Harvest Vinccler

recorded deferred revenue of $9.0 million for 2005 deliveries pending clarification on the calculation of crude prices under the Transitory Agreement.

Cash and Cash Equivalents

Cash equivalents include money market funds and short term certificates of deposit with original maturity dates of less than three months. At March 31, 2006, Harvest Vinccler had 17.0 billion Venezuela Bolivars (“Bolivars”) which are shown in the March 31, 2006 financial statements as $7.9 million in cash and cash equivalents. Harvest Vinccler expects to be able to utilize the Bolivars received to date. However, to the extent that Harvest Vinccler receives additional Bolivars in excess of its internal needs, there may be limited means to convert excess Bolivars into U.S. Dollars or other foreign currencies, and there would be a loss on any conversion where the exchange rate is above the official rate of 2,150 Bolivars to the U.S. Dollar.

Minority Interests

We record a minority interest attributable to the minority shareholder of our Venezuela subsidiaries. The minority interest in net income and losses is subtracted or added to arrive at consolidated net income. COMPREHENSIVE INCOME Statement of Financial Accounting Standards No. 130 ("SFAS 130") requires that all items required to be recognized under accounting standards as components of comprehensive income, be reported in a financial statement that is displayed with the same prominence as other financial statements. We reflected unrealized mark-to-market gains from cash flow hedging activities as other comprehensive income during the first quarter 2005

Derivatives and ~~in accordance with SFAS 130, have provided a separate line in the unaudited consolidated statement of operations. DERIVATIVES AND HEDGING~~Hedging

Statement of Financial Accounting Standards No. 133 ("(“SFAS ~~133"~~133”), as amended, establishes accounting and reporting standards for derivative instruments and hedging activities. All derivatives are recorded on the balance sheet at fair value. To the extent that the hedge is determined to be effective, changes in the fair value of derivatives for qualifying cash flow hedges are recorded each period in other comprehensive income. Our derivatives have been designated as cash flow hedge transactions in which we hedge the variability of cash flows related to future oil prices for some or all of our forecasted oil production. The changes in the fair value of these derivative instruments have been reported in other comprehensive income because the highly effective test was met, and have been reclassified to earnings in the period in which earnings are impacted by the variability of the cash flows of the hedged item.

In August 2004, Harvest Vinccler hedged a portion of its oil sales for calendar year 2005 by purchasing a ~~West Texas Intermediate ("WTI")~~WTI crude oil put for 5,000 barrels of oil per day. The put cost was $4.24 per barrel, or $7.7 million, and has a strike price of $40.00 per barrel. In September 2004, Harvest Vinccler hedged an additional portion of its calendar year 2005 oil sales by purchasing a second WTI crude oil put for 5,000 barrels of oil per day. The put cost was $3.95 per barrel, or $7.2 million, and has a strike price of $44.40 per barrel. Due to 6 the amended pricing structure as revised by the Transitory Agreement for our Venezuelan oil, these two puts have the economic effect of hedging approximately ~~20,800~~21,500 barrels of oil per day for an average of ~~$18.29~~$17.72 per barrel. These puts qualify under the highly effective test and the mark-to-market loss at March 31, 2005 is included in other comprehensive loss.

Accumulated Other Comprehensive Loss consisted of $9.9 million ~~and $0.7 million~~ ($6.5 ~~million and $0.5~~ million net of tax) at March 31, 2005, ~~and December 31, 2004, respectively,~~ of unrealized losses on our crude oil puts. Oil sales for the quarter ended 2005 included $3.7 million loss in amortization of the put option cost. Deferred net losses recorded in Accumulated Other Comprehensive Loss at March 31, 2005 ~~and December 31, 2004 are expected to be~~was reclassified to earnings during 2005.

We ~~continue to assess production levels and commodity prices in conjunction with our capital resources and liquidity requirements. ASSET RETIREMENT LIABILITY~~have not entered into any hedging activities for 2006.

Asset Retirement Liability

Effective January 1, 2003, we adopted Statement of Financial Accounting Standards No. 143, ~~"Accounting~~“Accounting for Asset Retirement ~~Obligations" ("~~Obligations” (“SFAS ~~143"~~143”). SFAS 143 requires entities to record the fair value of a liability for a legal obligation to retire an asset in the period in which the liability is incurred if a reasonable estimate of fair value can be made. No wells were abandoned in the quarter ended March 31, ~~2005,~~2006, and ~~nine~~no wells were abandoned in the year ended December 31, ~~2004.~~2005. Changes in asset retirement obligations during the ~~2005~~ first quarter of 2006 and the year ended December 31, ~~2004~~2005 were as follows:

~~EARNINGS PER SHARE~~


	March 31,			December 31,
	2006			2005
Asset retirement obligations beginning of period	$	2,129		$	1,941
Liabilities recorded during the period		—			96
Liabilities settled during the period		—			—
Revisions in estimated cash flows		(7	)		(17	)
Accretion expense		31			109

Asset retirement obligations end of period	$	2,153		$	2,129

Earnings Per Share

Basic earnings per common share ~~("EPS"~~(“EPS”) are computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. The weighted average number of common shares outstanding for computing basic EPS was ~~36.8~~37.1 million and ~~35.8~~36.8 million for the first quarter ~~2005~~2006 and ~~2004,~~2005, respectively. Diluted EPS reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. The weighted average number of common shares outstanding for computing diluted EPS, including dilutive stock options, was ~~38.6~~38.5 million and ~~37.9~~38.6 million for the first quarter 2006 and 2005, ~~and 2004,~~ respectively.

An aggregate of ~~1.0~~2.1 million and ~~1.5~~1.0 million options and warrants were excluded from the earnings per share calculations because their exercise price exceeded the average price for the first quarter 2006 and 2005, ~~and 2004,~~ respectively. ~~STOCK-BASED COMPENSATION~~

Stock-Based Compensation

At March 31, ~~2005,~~2006, we had several stock-based employee compensation plans, which are more fully described in Note 5 in our Annual Report on Form 10-K for the year ended ~~2004.~~2005. Prior to 2003, we accounted for those plans under the recognition and measurement provisions of Accounting Principles Board ~~("APB"~~(“APB”) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. Effective January 1, 2003, we adopted the fair value recognition provisions of SFAS Statement No. 123 ("(“SFAS ~~123"~~123”), Accounting for Stock-Based Compensation, as amended by Statement of Financial accounting Standards No. 148 (“SFAS 148”), prospectively to all employee awards granted, modified, or settled after January 1, 2003. Effective January 1, 2005, we adopted Statement of Financial Accounting Standard 123 (revised 2004) Share-Based Payment (“SFAS 123R”) to all employee awards granted, modified, or settled after October 1, 2005. Awards under our plans vest in periodic installments after one year of their grant and expire ten years from grant date. Therefore, the cost related to stock-based employee compensation included in the determination of net income in the first quarter ~~2005~~2006 and ~~2004~~2005 is less than that which would have been recognized if the fair value based method had been applied to all awards since the original effective date of SFAS 123. The following table illustrates the effect on net income and earnings per share if the fair value based method had been applied to all outstanding and unvested awards in each period. 7

New Accounting Pronouncements

In ~~March 2005,~~February 2006, the Financial Accounting Standards Board ~~("FASB'~~(“FASB”) issued Staff Interpretation No. 46(R) - 5 Consolidation of Variable Interest Entities ("FSP FIN 46(R) - 5"), which addresses the consolidation of variable interest entities ("VIEs") by business enterprises that are the primary beneficiaries. FSP FIN 46(R) - 5 is applicable to both nonpublic and public reporting enterprises. Application is required in financial statements for the first reporting period beginning after March 3, 2005 in accordance with the transition provisions of FSP FIN 46(R) - 5. The adoption of this interpretation will not impact our consolidated financial position, results of operations or cash flows. In March 2005, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin 107 ("SAB 107") which provides guidance on Statement of Financial Accounting Standard ~~123 (revised 2004) Share-Based Payment ("~~155 – Accounting for Certain Hybrid Financial Instruments (“SFAS ~~123R"~~155”)~~. Application~~, which eliminates the exemption from applying SFAS 133 to interests in securitized financial assets so that similar instruments are accounted for similarly regardless of the form of the instruments. SFAS 155 also allows the election of fair value measurement at acquisition, at issuance, or when a previously recognized financial instrument is ~~required~~subject to a remeasurement event. Adoption is effective for ~~public companies for annual periods~~all financial instruments acquired or issued after the beginning of the first fiscal year that ~~begin~~begins after ~~June~~September 15, ~~2005.~~2006. Early adoption is permitted. The ~~guidance provided in SAB 107~~adoption of SFAS 155 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In ~~April 2005,~~March 2006, the FASB issued ~~Staff Interpretation No. 19-1 ("FSP 19-1")~~Statement of Financial Accounting Standard 156 – Accounting for ~~Suspended Well Costs,~~Servicing of Financial Assets (“SFAS 156”), which ~~provides guidance~~requires all separately recognized servicing assets and servicing liabilities be initially measured at fair value. SFAS 156 permits, but does not require, the subsequent measurement of servicing assets and servicing liabilities at fair value. Adoption is required as of the beginning of the first fiscal year that begins after September 15, 2006. Early adoption is permitted. The adoption of SFAS 156 is not expected to have a material effect on the accounting for exploratory well costs and proposes an amendment to FASB Statement No. 19 ("FASB 19"), Financial Accounting and Reporting by Oil and Gas Producing Companies. The guidance in FSP 19-1 applies to enterprises that use the successful efforts method of accounting as described in FASB 19. The guidance in FSP 19-1 will not impact our consolidated financial position, results of operations or cash flows. ~~RECLASSIFICATIONS Certain items in 2004 have been reclassified to conform to the 2005 financial statement presentation. 8~~ ~~NOTE~~

Uracoa Municipality Tax ~~Assessments.~~Assessments. In July 2004, Harvest Vinccler received three tax assessments from a tax inspector for the Uracoa municipality in which part of the South Monagas Unit is located. A protest to the assessments was filed with the municipality, and in September 2004 the tax inspector responded in part by affirming one of the assessments and issuing a payment order. Harvest Vinccler has filed a motion with the tax court in Barcelona, Venezuela, seeking to enjoin the payment order and dismiss the assessment. We dispute all of the tax assessments and believe we have a substantial basis for our positions. We are unable to estimate the amount or range of any possible loss.

Libertador Municipality Tax Assessment. In April 2005, Harvest Vinccler received a tax assessment from a tax inspector for the Libertador municipality in which part of the South Monagas Unit is located. Harvest Vinccler has submitted a protest to the assessment at the Mayor’s Office, and if no favorable resolution is obtained, it will file a motion with the tax court seeking to enjoin the payment order and dismiss the assessment. We dispute the allegations set forth in the assessment and believe we have a substantial basis for our position. We are unable to estimate the amount or range of any possible loss.

On July 22, 2005, the SENIAT, the Venezuelan income tax authority, issued a preliminary tax assessment to Harvest Vinccler of 184 billion Venezuelan Bolivars related to fiscal years 2001 through 2004. At the official exchange rate of 2,150 Bolivars per U.S. Dollar, the dollar equivalent of the preliminary tax assessment is approximately $85 million. In addition, the SENIAT imposed penalties equal to 10 percent of the preliminary tax assessment claim for a total claim of 202 billion Bolivars, or approximately $94 million. Upon review of the preliminary tax assessment, we determined not to contest two elements of the claim and made payments totaling 11.3 billion Bolivars or $5.3 million in August and September, 2005. In September and October 2005, we filed a response and evidentiary support with the SENIAT contesting all other claims. While the SENIAT has not notified Harvest Vinccler of any tax assessment for the 2005 tax year, it will likely do so on the common elements of the tax assessment, including the applicable tax rate. We believe Harvest Vinccler has met its tax obligations in all material respects. The SENIAT and Harvest Vinccler have formed a working group to review the tax assessment for possible resolution of these claims. We intend to take all measures necessary to protect our rights, and will vigorously challenge all elements of the tax assessment that are not supported by Venezuelan law.

International Arbitration. As a result of the actions taken by PDVSA, the Ministry of Energy and Petroleum (“MEP”) and the SENIAT, in July 2005, we delivered formal notices to Venezuelan government officials of an investment dispute under Venezuelan law and bilateral investment treaties entered into by the government of Venezuela. The bilateral investment treaties and Venezuelan law provide for international arbitration of investment disputes conducted through the International Centre for Settlement of Investment Disputes of the World Bank.

We are a defendant in or otherwise involved in other litigation incidental to our business. In the opinion of management, there is no such litigation which will have a material adverse impact on our financial condition, results of operations and cash flows. 9 ~~NOTE~~

Note 6 ~~- CHINA OPERATIONS In March 2005, China National Offshore Oil Corporation ("CNOOC") granted us an extension of Phase 1~~— Venezuela Operations

Under the terms of the ~~Exploration Period~~OSA with PDVSA related to the reactivation and further development of the Uracoa, Tucupita and Bombal fields in Venezuela, a service fee payment to Harvest Vinccler is due by the end of the second month after the end of each calendar quarter. In August 2005, Harvest Vinccler entered into the Transitory Agreement with PDVSA. The Transitory Agreement provides that effective January 1, 2005, the total amounts paid under the OSA could not exceed 66.67 percent of the total value of the crude oil as determined under an Annex to the Transitory Agreement. Under the fee limit in the Transitory Agreement, the new fee has historically averaged approximately 47 percent of the price of WTI. Quarterly payments for ~~the WAB-21 contract area~~oil and natural gas revenues have been received 75 percent in U.S. Dollars and 25 percent in Bolivars. The OSA stipulates payment is to ~~May 2007. WAB-21 represents the $2.9 million excluded from the full cost pool as reflected on our~~be in U.S. Dollars or a currency selected by Harvest Vinccler.

On March 31, ~~2005~~2006, Harvest Vinccler signed a Memorandum of Understanding with PDVSA Petroleo, S.A. and ~~December 31, 2004 balance sheets.

Upon completion of Venezolana de Inversiones y Construcciones Clerico, C.A., which owns 20 percent of Harvest Vinccler. This agreement was terminated on September 19, 2004. Vinsa provided $0.4 million in construction services for our Venezuelan field operations for the ~~first quarter 2004. 11~~ ~~ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS~~conversion, a Harvest Natural Resources, Inc. ~~("Harvest"~~affiliate (“Harvest”) will own 40 percent of the shares of the Mixed Company (32 percent net to Harvest) and CVP will own the remaining 60 percent. Conversion of the OSA to the Mixed Company is subject to 1) completion of definitive agreements, 2) finalization of agreement on additional consideration, 3) approval by the board of directors of the entities which control Harvest Vinccler, 4) approval by the shareholders of Harvest and 5) approval by the Venezuelan MEP and the Venezuelan National Assembly. Upon completion of the conversion, there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006.

The impact, timing and likelihood of the conversion to the Mixed Company cannot be fully ascertained at this time. The 40 percent ownership in the Mixed Company will likely be accounted for under the equity method of accounting with a minority interest to reflect our net 32 percent interest. We will no longer be allowed to consolidate our Venezuelan interest as of April 1, 2006.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Harvest Natural Resources, Inc. (“Harvest” or the ~~"Company"~~“Company”) cautions that any forward-looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995) contained in this report or made by management of the Company involve risks and uncertainties and are subject to change based on various important factors.

In accordance with the provisions of the Private Securities Litigation Reform Act of 1995, we caution you that important factors could cause actual results to differ materially from those in the forward-looking statements. Such factors include our concentration of operations in Venezuela, the political and economic risks associated with international operations (particularly those in Venezuela), the anticipated future development costs for our undeveloped ~~proved~~ reserves, successful conversion of Venezuelan assets to the Mixed Company and relationship with a majority owner, the risk that actual results may vary considerably from reserve estimates, the dependence upon the abilities and continued participation of certain of our key employees, the risks normally incident to the operation and development of oil and natural gas properties, the permitting and drilling of oil and natural gas wells, the availability of materials and supplies necessary to projects and operations, the price for oil and natural gas and related financial derivatives, changes in interest rates, basis risk and counterparty credit risk in executing commodity price risk management activities, the ~~Company's~~Company’s ability to acquire oil and natural gas properties that meet its objectives, changes in operating costs, overall economic conditions, political instability, civil unrest, acts of terrorism, currency and exchange risks, currency controls, changes in existing or potential tariffs, duties or quotas, changes in taxes, changes in governmental policy, availability of sufficient financing, changes in weather conditions, and ability to hire, retain and train management and personnel. A discussion of these factors is included in our Annual Report on Form 10-K for the year ended ~~2004,~~2005, which includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Quarterly Report. ~~VENEZUELA~~

Venezuela

In our Annual Report on Form 10-K for the year ended ~~2004,~~2005, we described ~~recent~~the events in Venezuela that ~~could~~have and may continue to adversely affect our ~~oil and gas production. As~~operations. These events were part of a ~~result~~series of ~~these events, on January 18, 2005 we announced that our 80 percent owned Venezuelan subsidiary, Harvest Vinccler, C.A. ("Harvest Vinccler"), was suspending its drilling program. We also reported that~~actions initiated by the ~~Ministry~~government of ~~Energy and Petroleum ("MEP") stated that~~Venezuela to compel companies with operating service agreements to convert those agreements into new companies in which Petroleos de Venezuela, S.A. ~~("PDVSA"~~(“PDVSA”) ~~wanted to renegotiate~~has a majority interest. In our Annual Report on Form 10-K, we also described the ~~terms of~~risk factors created by the ~~active operating service agreements~~situation in Venezuela, ~~including the South Monagas Unit Operating Service Agreement ("OSA") held by Harvest Vinccler. The OSA represents all of our production.~~ including:

	•		Our interests in Venezuela may be unlawfully expropriated by the Venezuelan government.

	•		Our only source of production may be reduced further by actions of the Venezuelan government.

	•		Future payments to Harvest Vinccler may be adversely affected by actions of the Venezuelan government.

	•		Actions by the SENIAT to collect claimed back taxes could threaten the viability of our Venezuelan operations.

	•		The actions of the Venezuelan government may cause us to file for international arbitration.

	•		Harvest Vinccler may not be able to reach agreement on the terms of the Mixed Company and there is a risk any agreement will not receive the necessary approvals.

On March 31, 2006, Harvest Vinccler signed a Memorandum of ~~MEP~~Understanding (“MOU”) with PDVSA Petroleo, S.A. and ~~President of PDVSA held~~Corporación Venezolana del Petroleo S.A. (“CVP”) to convert its Operating Service Agreement (“OSA”) to a press conference in which he questioned the legality of all the operating service contracts entered into by PDVSA, and imposed a cap on the crude oil production service fees paid under those agreements equalmixed company (the “Mixed Company”) subject to ~~two-thirds~~certain conditions. Upon completion of the ~~market value per barrel~~conversion, a Harvest Natural Resources, Inc. affiliate (“Harvest”) will own 40 percent of ~~crude. Based~~the shares of the Mixed

Company (32 percent net to Harvest) and CVP will own the remaining 60 percent. Conversion of the OSA to the Mixed Company is subject to 1) completion of definitive agreements, 2) finalization of agreement on ~~our estimates, as indirectly confirmed~~additional consideration, 3) approval by ~~Venezuelan government officials,~~ the ~~oil fee paid to~~board of directors of the entities which control Harvest Vinccler, ~~in 2004 was approximately two-thirds~~4) approval by the shareholders of ~~market value. Consequently, we do not believe~~Harvest and 5) approval by the ~~two-thirds cap on service fees will have a significant impact on us. The Minister~~Venezuelan Ministry of ~~MEP also stated in~~Energy and Petroleum (“MEP”) and the ~~press conference that in the next six months all~~Venezuelan National Assembly. Upon completion of the ~~operating service agreements are~~conversion, there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006.

Under the MOU, the terms and conditions of the migration to the Mixed Company shall be ~~converted to incorporated joint ventures under the 2001 Venezuelan Organic Hydrocarbon Law ("OHL") through negotiation~~in substantial conformity with the ~~contract holders. He also stated that no contracts would be revoked. The OHL requires that~~form of Conversion Contract attached to the ~~Venezuelan Government have a majority ownership stake in the joint venture. The directives~~MOU. Significant elements of the ~~Minister of MEP~~draft Conversion Contract include:

	•		Exploration and production activities may be conducted for a maximum period of 20 years.

	•		Operations will be conducted in accordance with a business plan attached to the contract. In addition, the Mixed Company will adopt policies and procedures governing its operations.

	•		The OSA will be cancelled upon completion of the conversion process.

	•		Harvest Vinccler will be paid for the first quarter 2006 deliveries under the terms of the OSA as amended by the Transitory Agreement.

	•		Except under very limited circumstances, shares held in the Mixed Company may not be directly or indirectly transferred without the consent of the MEP and, under certain circumstances, subject to a right of first refusal by CVP.

	•		Matters requiring shareholder approval may be approved by a simple majority with the exception of certain specified matters which require approval by at least 75 percent of the shares.

	•		The board of directors of the Mixed Company shall consist of five directors, three of whom are appointed by CVP and two of whom are appointed by Harvest. The board may act by a simple majority of directors.

	•		Each shareholder has the right to nominate a percentage of management personnel equal to its share ownership. CVP has the right to nominate the General Manager for the Mixed Company and Harvest has the right to nominate the Technical and Operations Manager.

	•		All crude oil production shall be sold to a PDVSA affiliate under a reference price intended to reflect the export value to the market for the type of crude delivered. Payment is in U.S. Dollars.

	•		Associated natural gas is sold to PDVSA at a price equivalent to that in the OSA adjusted for royalties. Payment is in Venezuelan Bolivars (“Bolivars”).

Under current tax and royalty legislation, the ~~press conference have been confirmed in~~Mixed Company will pay a ~~letter from PDVSA to Harvest Vinccler. Government officials have also announced that~~33.3 percent royalty and the income tax rate ~~paid by~~will be 50 percent. In addition, the Mixed Company will be subject to a “special advantage” payment obligation calculated to assure that Venezuela never receives less than 50 percent of the value of the hydrocarbons produced.

In addition to Harvest Vinccler, sixteen other oil companies ~~holding~~each signed a memorandum of understanding for the conversion of their operating service agreements ~~would be increased from 34 percent~~ to 50mixed companies. The percentage ownership in the mixed companies varied among the signing companies, but no company received more than 40 percent. The general guidelines for these mixed companies were approved by the Venezuelan ~~income tax authority, SENIAT, has~~National Assembly on March 30, 2006. The Minister of the MEP had previously stated that after March 31, 2006, all operating services agreements would cease to exist, and on April 1, 2006, the ~~tax increase is effective~~Minister announced that the government had taken control of fields operated by two companies who declined to sign a memorandum of understanding. On April 5, 2006, the National Assembly passed legislation declaring all operating services agreements illegal.

The financial reporting impact of the conversion to the Mixed Company cannot be fully ascertained at this time. Upon conversion, the 40 percent ownership in the Mixed Company will likely be accounted for under the

equity method of accounting with a minority interest to reflect our net 32 percent interest. We will no longer be able to consolidate our Venezuelan interest as of April ~~18, 2005.~~1, 2006 and will be required to reflect the equity income (or loss) as a separate line in the future Consolidated Statements of Operations.

Execution of the MOU represents an important milestone in the successful conversion of our interests in Venezuela to the Mixed Company. However, the ~~increase is not~~timing and outcome of the ~~result~~process remains uncertain and significant risks remain. The MOU contains a number of ~~a legislative change in~~conditions to completing the ~~tax laws, and SENIAT has not indicated how this increase might be implemented or whether it might attempt~~conversion to ~~apply it~~the Mixed Company, some of which are largely beyond our control. There are also conditions that depend upon successfully reaching agreement with the government of Venezuela on matters that affect the value to ~~prior tax years. The implementation~~us of an income tax increase from 34 percent to 50 percent, without compensating values, will have a material adverse effect on our financial condition, results of operations and cash flows. Separately, SENIAT announced it is auditing tax payments by the ~~companies with operating service agreements. SENIAT has started a tax audit of Harvest Vinccler for tax years beginning with 12~~ ~~2001.~~Mixed Company. We believe that Harvest Vinccler has met its obligations under the Venezuelan tax laws in all material respects. Harvest Vinccler has exchanged proposals and is in discussions with PDVSA and MEP to resolve our 2005 capital program and production issues under the OSA and also to establish a longer term path forward. These discussions include converting the OSA into an incorporated joint venture under the OHL. It is expected that the joint venture company would also include additional assets contributed by PDVSA. While we areremain hopeful of ~~achieving~~reaching a ~~business solution~~mutually acceptable agreement with the MEP, the SENIAT and PDVSA on the final terms of the Mixed Company while preserving the value of our investment in Harvest Vinccler. However, no assurance can be given asthat we will satisfy all of the conditions to ~~either~~conversion, and until there is clarity and resolution, uncertainty over the ~~outcome~~future of our investment in Venezuela will continue to affect our performance. The results from operations for this interim period are subject to Harvest Vinccler being paid for the first quarter 2006 deliveries under the terms of the OSA. We continue to consider alternatives to unlocking the underlying value of our Venezuelan assets for our shareholders. This may include a sale or exchange of all or part of our Venezuelan interests.

In our Annual Report on Form 10-K for the year ended 2005, we discussed the preliminary income tax assessment issued by the SENIAT against Harvest Vinccler for the tax years 2001 through 2004. While the SENIAT has not notified Harvest Vinccler of any tax assessment for the 2005 tax year, it will likely do so on the common elements of the tax assessment, including the tax rate. Harvest Vinccler has paid income taxes for the 2005 tax year at a 34 percent tax rate, whereas in its preliminary tax assessment the SENIAT contends the rate is 50 percent for all years after 2001. At the 50 percent rate, Harvest Vinccler’s tax liability for 2005 would increase by an estimated $17.9 million. While we continue to contest the SENIAT assessment, including the 50 percent tax rate, we are actively working with the SENIAT to resolve all claims, including any that would relate to 2005.

SeeItem 1A Risk Factorsfor a discussion of the risks associated with the timing and outcome of ~~our discussions.

Operating expenses during the first quarter ~~2005 compared~~2006 were relatively consistent with ~~2004. Natural gas sales quantities decreased 6 percent (from 7.8 billion cubic feet ["Bcf"]~~that of ~~gas in 2004 to 7.3 Bcf in 2005)~~the first quarter 2005. Depletion and amortization expense per Boe produced during the first quarter ~~2005 compared with 2004. Revenue for~~2006 was $3.74 versus $2.99 in the first quarter of 2005. The increase was due to the reduction of proved undeveloped reserves because of the actions taken by the Venezuelan government in 2005 under our OSA. General and ~~2004 includes 0.2 MBbls of oil, respectively, at a $7.00 fixed price associated with the gas sales contract. Our revenues~~administrative expense was higher due to increased ~~$22.2 million, or 57 percent, during the first quarter 2005 compared with 2004. This was~~business development activities. Taxes other than on income were higher due to an increase in ~~oil sales volumes and oil prices. Our sales quantities for~~ the first quarter 2005 from Venezuela were 3.7 MBoe compared with 3.2 MBoe in 2004. Our operating expenses increased $1.5 million, or 21 percent, for the first quarter 2005 compared with 2004. This increase was primarily due to the suspended drilling program and the fixed costs of our support facilities being allocated to operating expense. Depletion, depreciation and amortization increased $3.5 million, or 43 percent, during the first quarter 2005 compared with 2004 due to increased oil production. Depletion expense per MBoe produced during the first quarter 2005 was $2.99 compared with $2.41 during 2004. The increase was primarily due to increased future development costs. General and administrative expenses increased $1.4 million, or 38 percent, for the first quarter 2005 compared with 2004. This was, in part, due to restricted stock bonuses, additional costs associated with Sarbanes-Oxley compliance offset by a decrease in liability under our deferred compensation plan for directors. Taxes other than on income increased $0.5 million, or 44 percent, during the first quarter 2005 compared with 2004. This was due to increased Venezuelan municipal ~~taxes which result from higher oil revenues and an increase in the municipal~~ tax ~~rate in Uracoa.~~rate.

Investment income and other increased ~~$0.2 million, or 78 percent, during the first quarter 2005 compared with 2004. This was~~ due to higher interest rates earned on higher average cash balances. Interest expense decreased ~~$2.2 million, or 90 percent, during the first quarter 2005 compared with 2004~~ due to lower average outstanding debt balances ~~for 2005~~in the first quarter 2006 compared to ~~2004. In November 2004, we redeemed all $85 million of our 2007 Notes.~~2005. Net gain on exchange rates ~~increased $3.4 million for the first quarter 2005 compared with 2004.

Bolivar currency controls imposed in February 2003 fix the~~official exchange rate between the Bolivar and the U.S. Dollar in the first quarter 2006. Bolivar currency controls imposed in February 2003 fixed the exchange rate between the Bolivar and U.S. Dollar and restricts the ability to exchange ~~Venezuelan~~ Bolivars for ~~dollars~~U.S. Dollars and vice versa. On March 3, 2005, the official exchange rate was adjusted from 1,920 Bolivars for each U.S. Dollar to 2,150 Bolivars for each U.S. Dollar. ~~We realized income before income taxes and minority interest of $36.7 million during~~There has been no change to the ~~first quarter 2005 compared with income of $15.7 million~~official exchange rate since that time.

The effective tax rate increased in the first quarter ~~2004. The increase was primarily attributable~~2006 to 45 percent from 37 percent in 2005 as a result of reporting a higher ~~crude oil volumes~~percentage of income in a higher tax jurisdiction. Our tax calculations do not include the tax increases previously announced by the SENIAT.

Effects of Changing Prices, Foreign Exchange Rates and an increase in crude oil prices in 2005. Income tax expense increased $7.9 million due to higher Venezuela pre-tax income. The effective tax rate during the first quarter 2005 was relatively consistent with that of the first quarter 2004. The income before minority interest increased $13.1 million for the first quarter 2005 compared with 2004. This increase was primarily due to increased production and oil prices during the first quarter of 2005. EFFECTS OF CHANGING PRICES, FOREIGN EXCHANGE RATES AND INFLATIONInflation

Our results of operations and cash flow are affected by changing oil prices. Fluctuations in oil prices may affect our total planned development activities and capital expenditure program. In August and September 2004, Harvest Vinccler hedged a portion of its oil sales for calendar year 2005 by purchasing two West Texas Intermediate ~~("WTI")~~ crude oil puts. SeeNote 1 -– Organization and Summary of Significant Account Policies, Derivatives and ~~Hedging.~~Hedging.

Venezuela imposed currency exchange restrictions in February 2003 and adjusted the official exchange rate ~~in February 2004~~between Bolivars and ~~again~~U.S. Dollars in March ~~2005. During~~2005 from 1,920 Bolivars to 2,150 Bolivars to the ~~first quarter 2005, our net foreign~~U.S. Dollar. There has been no change in the official exchange ~~gain attributable to our international operations was $2.8 million. No gains or losses were recognized from February 2004 to February 2005. However, there~~rate since that time. There are many factors affecting foreign exchange rates and resulting exchange gains and losses, 14 many of which are beyond our control. We have recognized significant exchange gains and losses in the past, resulting from fluctuations in the relationship of the Venezuelan currency to the U.S. Dollar. It is not possible for us to predict the extent to which we may be affected by future changes in exchange rates and exchange controls. ~~We do~~PDVSA is currently remitting 25 percent of the quarterly oil service fees in Bolivars. Due to currency control regulations, it may not ~~expect the currency conversion restrictions~~be possible to convert excess Bolivars into U.S. Dollars or other foreign currencies. Continued substantial payment by PDVSA in Bolivars or the ~~adjustment in~~inability to convert the ~~exchange rate to~~Bolivars into U.S. Dollars could have a material ~~impact~~adverse effect on ~~us at this time.~~our financial condition.

Within the United States, inflation has had a minimal effect on us, but it is potentially an important factor in results of operations in Venezuela. With respect to Harvest Vinccler, a significant majority of the sources of funds, including the proceeds from oil sales, our contributions and credit financings, are denominated in U.S. Dollars, while ~~a minor amount of~~many local transactions in Venezuela are conducted in local ~~currency.~~currency such as local salaries, municipal and income taxes. If the rate of increase in the value of the U.S. Dollar compared with the Bolivar continues to be less than the rate of inflation in Venezuela, then inflation could be expected to have an adverse effect on Harvest Vinccler. ~~CONCLUSION While we can give you no assurance, we believe that our cash flow from operations~~

Item 3. Quantitative and our existing cash balance will provide sufficient capital resources and liquidity to fund execution of our business plan including capital expenditures. We have protected a portion of our 2005 cash flow by purchasing two WTI crude oil puts for an average of $42.20 a barrel floor on 10,000 BOPD. Due to the pricing structure for our Venezuelan oil, this has the economic effect of hedging approximately 20,800 BOPD. Our expectation is based upon our current estimate of projected prices, production levels, and our assumptions that we will be allowed to carry out our capital program on acceptable terms, that there will be no disruptions or limitations on our production and that PDVSA will pay our invoices timely. Actual results could be materially affected if there is a significant change in our expectations or assumptions (see Item 2. Venezuela). Future cash flows are subject to a number of variables including, but not limited to, the level of production, prices, as well as various economic and political conditions that have historically affected the oil and natural gas business. Prices for oil are subject to fluctuations in response to changes in supply, market uncertainty and a variety of factors beyond our control. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKQualitative Disclosures About Market Risk

We are exposed to market risk from adverse changes of the situation in Venezuela, and adverse changes in oil and natural gas prices, interest rates, foreign exchange and political risk, as discussed in our Annual Report on Form 10-K for the year ended ~~2004. In March 2005, Venezuela adjusted the official exchange rate. Other than this change, the~~2005. The information about market risk for the first quarter ~~2005~~2006 does not differ materially from that discussed in the Annual Report on Form 10-K for the year ended ~~2004. ITEM~~2005.

Item 4. ~~CONTROLS AND PROCEDURES~~Controls and Procedures

The Securities and Exchange Commission, among other things, adopted rules requiring reporting companies to maintain disclosure controls and procedures to provide reasonable assurance that a registrant is able to record, process, summarize and report the information required in the ~~registrant's~~registrant’s quarterly and annual reports under the Securities Exchange Act of 1934 (the ~~"Exchange Act"~~“Exchange Act”). While we believe that our existing disclosure controls and procedures have been effective to accomplish these objectives, we intend to continue to examine, refine and formalize our disclosure controls and procedures and to monitor ongoing developments in this area. There have not been any changes in our internal control over financial reporting (as such term is defined in ~~Rules~~Rule 13a-15(f) ~~and~~or 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ~~EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES.~~

Evaluation of Disclosure Controls and Procedures.We have established disclosure controls and procedures to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors. 15

Based on their evaluation as of March 31, ~~2005,~~2006, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in ~~Rules~~Rule 13a-15(e) ~~and~~or 15d-15(e) under the Exchange Act) are effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is 1) recorded, processed, summarized and reported within the time periods as specified in the Securities and Exchange ~~Commission's~~Commission’s rules and ~~forms. 16~~ forms and 2) accumulated and communicated to our management, including our principal executive and principal financial officers, to allow timely decisions regarding required disclosure.

Item 1. ~~LEGAL PROCEEDINGS~~ Legal Proceedings

See our Annual Report on Form 10-K for the year ended ~~2004~~2005 for a description of certain other legal proceedings. There have been no material developments in such legal proceedings since the filing of such Annual Report. ~~ITEM~~

Item 1A. Risk Factors

On March 31, 2006, Harvest Vinccler signed a MOU with PDVSA Petroleo, S.A. and CVP to convert its OSA to the Mixed Company subject to certain conditions. Upon completion of the conversion, a Harvest affiliate will own 40 percent of the shares of the Mixed Company (32 percent net to Harvest) and CVP will own the remaining 60 percent. Conversion of the OSA to the Mixed Company is subject to 1) completion of definitive agreements, 2) finalization of agreement on additional consideration, 3) approval by the board of directors of the entities which control Harvest Vinccler, 4) approval by the shareholders of Harvest and 5) approval by the Venezuelan MEP and the Venezuelan National Assembly. Upon completion of the conversion, there will be an adjustment between the parties to obtain the same economic result as if the conversion had been completed on April 1, 2006.

Some of the conditions to completing the conversion to the Mixed Company are largely beyond our control. There are also conditions that depend upon successfully reaching agreement with the government of Venezuela on matters that affect the value to us of the Mixed Company. In addition to the risks described in our Annual Report on Form 10-K for the year ended 2005, the timing and outcome risks associated with completing the conversion to the Mixed Company include:

After April 1, 2006, our operations in Venezuela are being conducted under an OSA the government no longer recognizes and which it claims is illegal. As such, our future ability to contractually recover our investments and be compensated for our services depends upon completing the process for the conversion of our interests to the Mixed Company.

Payment by PDVSA for first quarter 2006 deliveries, which represents virtually all of our revenues for the quarter, likely depends upon completing the process for the conversion of our interests to the Mixed Company.

	•		Harvest Vinccler remains subject to significant tax claims by the SENIAT, including the likely extension of some of those claims for the 2005 tax year. While Harvest Vinccler is actively working with the SENIAT to resolve all the claims, it may be unable to do so. If the claims are not resolved, this could impede or prevent conversion to the Mixed Company. The SENIAT could also seek to seize Harvest Vinccler assets, including the first quarter payment due from PDVSA.

	•		The resumption of any significant drilling operations is unlikely until conversion to the Mixed Company is completed.

	•		Upon conversion to the Mixed Company, we will be a minority interest owner and no longer have sole control over operations. Our control of the Mixed Company will be limited to our rights under the conversion agreement.

	•		If we are unable to successfully complete the conversion to the Mixed Company, it is likely that the Venezuelan government will take over Harvest Vinccler’s operations. In that event, we would pursue claims against the Venezuelan government.
