~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS ~~THREE AND SIX MONTHS ENDED JUNE 30,~~~~

~~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 ~~June 30, 2005,~~March 31, 2006, and the results of operations and cash flows for the ~~three~~first quarter 2006 and ~~six month periods ended June 30, 2005 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 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. ~~REPORTING AND FUNCTIONAL CURRENCY~~

~~Reporting and Functional Currency~~

~~The U.S. Dollar is our functional and reporting currency. ~~REVENUE RECOGNITION~~~~

~~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"~~(“PDVSA”), based on barrels of oil accepted by PDVSA during the quarter, using quarterly adjusted U.S. Dollar contract service fees per barrel. The ~~Operating Service Agreement ("OSA")~~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. ~~The maximum total fee is subject to quarterly adjustments to reflect changes in the average of certain world crude oil prices.~~ 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"~~Oil”). A portion of the Incremental Crude Oil is invoiced to PDVSA quarterly at a fixed price of $7.00 per Bbl. The ~~invoice is~~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 ~~and second~~ quarter ~~of 2005 for the~~2006 delivery of its crude oil and natural gas in accordance with the ~~terms described above and recognized its~~Transitory Agreement. However, Harvest Vinccler

recorded deferred revenue in a consistent manner with prior periods. For the first quarter deliveries, PDVSA remitted the amount due less $9.8 million. PDVSA did not provide an explanation to Harvest Vinccler for the underpayment, but we believe, based on public commentary, that it is attributable to a unilateral imposition of ~~a limit on service fees paid to all companies with operating service agreements to two-thirds of the 6~~ market value of the crude delivered to PDVSA. This limit was announced by The Ministry of Energy and Petroleum ("MEP") in April 2005. Regardless of the appropriateness or legality of such a limitation, we also believe that PDVSA has not properly calculated the unilateral limit it is placing on Harvest Vinccler's fees because it is understating the actual market value of the crude oil. We have notified PDVSA of this matter. Harvest Vinccler estimates that the second quarter would be impacted by $9.0 million iffor 2005 deliveries pending clarification on the ~~same limit were to be applied. We believe at this time we will collect the entire amount~~calculation of ~~fees due~~crude prices under the ~~contract~~Transitory Agreement.

~~Cash and ~~accordingly, have not recorded any allowance for either the collectibility~~Cash Equivalents~~

Cash equivalents include money market funds and short term certificates of ~~the receivable or adjustment to reduce reported revenues. CASH AND CASH EQUIVALENTS~~deposit with original maturity dates of less than three months. At ~~June 30, 2005,~~March 31, 2006, Harvest Vinccler had ~~58.0~~17.0 billion Venezuela Bolivars ~~("Bolivars"~~(“Bolivars”) which are shown in the ~~June 30, 2005~~March 31, 2006 financial statements as ~~$27.2~~$7.9 million in cash and cash equivalents. Harvest Vinccler ~~has a limited need for Bolivars in the conduct of its business but~~ 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, itthere may ~~not~~ be ~~possible, due to currency control regulations,~~limited means to convert ~~any future~~ excess Bolivars into U.S. Dollars or other foreign ~~currencies. MINORITY INTERESTS~~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 losses from cash flow hedging activities as other comprehensive loss during the second quarter 2005

~~Derivatives and ~~in accordance with SFAS 130, have provided a separate line in the unaudited consolidated statement of operations to reflect such loss. 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 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 ~~June 30,~~March 31, 2005 is included in other comprehensive loss.

Accumulated Other Comprehensive Loss consisted of ~~$7.2~~$9.9 million ~~and $0.7 million~~ ($~~4.8 million and $0.5~~6.5 million net of tax) at ~~June 30,~~March 31, 2005, ~~and December 31, 2004, respectively,~~ of unrealized losses on our crude oil puts. Oil sales for the ~~three and six month periods~~quarter ended 2005 included ~~losses of~~ $3.7 million ~~and $7.4 million, respectively,~~loss in ~~settlement~~amortization of the ~~hedges.~~put option cost. Deferred net losses recorded in Accumulated Other Comprehensive Loss at ~~June 30,~~March 31, 2005 ~~and December 31, 2004, is expected to be~~was reclassified to earnings during 2005. 7

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 ~~six months~~quarter ended ~~June 30, 2005~~March 31, 2006, and ~~nine~~no wells were abandoned in the year ended December 31, ~~2004.~~2005. Changes in asset retirement obligations during the ~~six months ended June 30, 2005~~first quarter of 2006 and the year ended December 31, ~~2004~~2005 were as follows:
~~June 30, December, 31 2005 2004 ----------- ------------~~ Asset retirement obligations beginning of period $ 1,941 $ 1,459 Liabilities recorded during the period -- 1,454 Liabilities settled during the period -- (540) Revisions in estimated cash flows (4) (470) Accretion expense 54 38 ----------- ------------ Asset retirement obligations end of period $ 1,991 $ 1,941 =========== ============

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 ~~36.9~~37.1 million and 36.8 million for the ~~three~~first quarter 2006 and ~~six months ended~~ 2005, ~~respectively, and 35.9 million for the three and six months ended 2004,~~ 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 38.5 million ~~for the three~~ and ~~six months ended 2005, respectively, and 38.2 million and 38.0~~38.6 million for the ~~three~~first quarter 2006 and ~~six months ended 2004,~~2005, respectively.

An aggregate of ~~2.0~~2.1 million and ~~1.8~~1.0 million options and warrants ~~to purchase common stock~~ were excluded from the earnings per share calculations because their exercise price exceeded the average price for the ~~three~~first quarter 2006 and ~~six months ended~~ 2005, respectively. An aggregate of 1.0 million options and warrants to purchase common stock were excluded from the earnings per share calculations because their exercise price exceeded the average price for the three and six months ended 2004. STOCK-BASED COMPENSATION

~~Stock-Based Compensation~~

At ~~June 30, 2005,~~March 31, 2006, we had several stock-based employee compensation plans, which are more fully described in Note 5 ~~to the consolidated financial statements included~~ 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 ~~of Financial Accounting Standards~~ No. 123 ("(“SFAS ~~123"~~123”), Accounting for Stock-Based Compensation, as amended by Statement of Financial ~~Accounting~~accounting Standards No. 148 ("(“SFAS ~~148"), Accounting for Stock-Based Compensation - Transition and Disclosure and Statement of Financial Accounting Standard 123 (revised 2004) Share-Based Payment ("SFAS 123R"~~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 ~~beginning~~after one year ~~after~~of their grant and expire ten years from ~~the~~ grant date. Therefore, the cost related to stock-based employee compensation included in the determination of net income in the ~~three~~first quarter 2006 and ~~six months ended~~ 2005 ~~and 2004~~ 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 ~~123R.~~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.

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.

Under the terms of ~~our~~the 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. ~~PDVSA did~~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 ~~make its first quarter payment for $64.8 million by the May 31, 2005 due date.

On June 29, 2005, Harvest Vinccler received $27.5 million in U.S. Dollars. From our calculations, assuming (solely for explanatory purposes) that the Bolivar could be used to purchase United States Dollars at the official exchange rate (approximately 2,150 Bolivars per each U.S. Dollar), the amounts disbursed by PDVSA and deposited in Harvest Vinccler's accounts are approximately $9.8 million less than the total amount due. Harvest Vinccler has notified PDVSA in writing that the underpayment and reported payment in Bolivars is ~~contrary to the terms of the OSA and demanded full and proper payment. Harvest Vinccler has a limited need for Bolivars in the conduct of its business but 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, it may not be possible, due to currency control regulations, to convert any future excess Bolivars into~~ U.S. Dollars or ~~other foreign currencies.

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.

(“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 ~~stability,~~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.

~~Venezuela~~

In our Annual Report on Form 10-K for the year ended ~~2004, and our Quarterly Report on Form 10-Q for the period ended March 31,~~ 2005, we described the events in Venezuela ~~affecting~~that have and may continue to adversely affect our oil and gas production and profitability. In January 2005, we announced that our 80 percent owned Venezuelan subsidiary, Harvest Vinccler, C.A. ("Harvest Vinccler"), was suspending its drilling program. We have stated thatoperations. These events were part of a ~~continuation in~~series of actions initiated by the ~~delay~~government of our drilling program or a curtailment of our oil and gas deliveries could have a material adverse effect on our financial condition, results of operations and cash flows. We also reported that the Ministry of Energy and Petroleum ("MEP") stated that Petroleos de Venezuela ~~S.A. ("PDVSA") wanted~~ to renegotiate the terms of the active operating service agreements in Venezuela, including the South Monagas Unit Operating Service Agreement ("OSA") held by Harvest Vinccler. In April 2005, MEP declared that the operating service agreements lack legal validity and that within the next six months all such agreements are to be converted into mixed companies under the 2001 Venezuelan Organic Hydrocarbon Law ("OHL") in which the State will have a majority ownership. MEP also imposed a cap on the service fees paid under the operating services agreements equal to two-thirds of the market value of the crude we deliver to PDVSA. At the time of this announcement, and based upon an indirect confirmation by government officials, we did not think the fee cap would have a significant impact on us (but see below). We also reported that the Venezuelan income tax authority, the SENIAT, announced that the income tax rate paid bycompel companies with operating service agreements ~~would be increased from 34 percent~~ to ~~50 percent and that~~convert those agreements into new companies in which Petroleos de Venezuela, S.A. (“PDVSA”) has a majority interest. In our Annual Report on Form 10-K, we also described the ~~SENIAT had started a tax audit of Harvest Vinccler for~~risk factors created by the ~~tax years beginning with 2001.~~ situation in Venezuela, 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, ~~2005,~~2006, Harvest Vinccler signed a Memorandum of Understanding (“MOU”) with PDVSA Petroleo, S.A. and Corporación Venezolana del Petroleo S.A.

Upon completion of the ~~preliminary~~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 in substantial conformity with the form of Conversion Contract attached to the MOU. Significant elements of the 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 ~~assessment is approximately $85 million.~~and royalty legislation, the Mixed Company will pay a 33.3 percent royalty and the income tax rate will be 50 percent. In addition, the ~~SENIAT imposed penalties equal~~Mixed Company will be subject to ~~10 percent of the preliminary tax assessment for~~ a ~~total claim of 202 billion Bolivars, or 13~~ approximately $94 million. The 10 percent penalty would be payable if we pay the preliminary tax assessment. We are in the process of reviewing the assessment, but believe Harvest Vinccler has met its tax obligations in all material respects. We intend to take all measures necessary to protect our rights, and will vigorously challenge all elements of the assessment that are not supported by Venezuelan law. Harvest Vinccler has the right to challenge the assessment from the SENIAT by filing an answer. After filing the answer, the SENIAT is required to issue the final assessment within one year. A final assessment by the SENIAT may also include additional penalties between 25 percent and 200 percent of the unpaid tax. The average penalty imposed by the SENIAT is 112.5 percent of the unpaid tax unless extenuating or aggravating circumstances apply. If a final assessment is issued, Harvest Vinccler can file an administrative appeal with the SENIAT. During the period of review by the SENIAT, any“special advantage” payment obligation is suspended. After exhausting administrative appeals, Harvest Vinccler may either pay the tax or file a judicial appeal. If a judicial appeal is filed, the payment obligation is suspended at the discretion of the court. While there are no set rules on suspending payment, often times it is permitted only if the taxpayer posts a bond or other security equalcalculated to 210 percent of the assessment. At the current level of assessment, and considering possible penalties, a requirement to pay the taxes or post security will have a material adverse affect on our financial condition, and may exceed our cash balance. In addition, the implementation of a 50 percent tax rate in the future or other changes in the interpretation or application of the tax laws, without compensating values, will have a material adverse effect on our financial position, results of operations or cash flows. In June 2005, we announcedassure that ~~PDVSA failed to make payment when due of an invoice in the amount of $64.8 million for first quarter deliveries. The payment was due on May 31, 2005. By letter dated June 23, 2005, PDVSA stated that~~Venezuela never receives less than 50 percent of the ~~amounts due would be paid in Bolivars, and that this amount would be subject~~value of the hydrocarbons produced.

In addition to ~~further adjustment based upon the amount of payments in foreign currency that~~ Harvest Vinccler, ~~is required~~sixteen other oil companies each signed a memorandum of understanding for the conversion of their operating service agreements to ~~make.~~mixed companies. The ~~letter added~~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 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 Minister announced that the ~~OSA would~~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 ~~amended to fix~~fully ascertained at this time. Upon conversion, the future percentage of payments that would be made in Bolivars. On June 28, 2005, Harvest Vinccler received payment of 59 billion Bolivars from PDVSA.

Execution of the MOU represents an important milestone in the successful conversion of our interests in Venezuela to the ~~extent~~Mixed Company. However, the timing and outcome of the process remains uncertain and significant risks remain. The MOU contains a number of conditions to completing the conversion to 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 us of the Mixed Company. We remain hopeful of reaching a 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 receives additional Bolivars~~Vinccler. However, no assurance can be given that we will satisfy all of the conditions to conversion, and until there is clarity and resolution, uncertainty over the future of our investment in ~~excess of its internal needs, it may not be possible, due~~Venezuela will continue to currency control regulations, to convert any future excess Bolivars into U.S. Dollars or other foreign currencies. Continued substantial payment by PDVSA in Bolivars or the inability to convert the Bolivars into U.S. dollars could have a material adverse effect onaffect our ~~financial position,~~performance. The results offrom operations ~~or cash flows. From our calculations, PDVSA's June 2005 payment~~for this interim period are subject to Harvest Vinccler ~~is approximately $9.8 million less than~~being paid for the ~~total amount due. We believe this shortfall is attributable to~~first quarter 2006 deliveries under the ~~unilateral imposition~~terms of the ~~limit on service fees previously announced by MEP. However, we also believe that PDVSA has not properly calculated~~OSA. We continue to consider alternatives to unlocking the ~~unilateral limit it is placing on Harvest Vinccler's fees because it is understating the actual market~~underlying value of ~~the crude oil we deliver to PDVSA. We have notified PDVSA~~our Venezuelan assets for our shareholders. This may include a sale or exchange of this matter. A continuation of the limit on fees as presently calculated by PDVSA would represent a significant reduction in the fees received by Harvest Vinccler. Harvest Vinccler has formally notified PDVSA that the underpayment and partial payment in Bolivars is contrary to the OSA and demanded contract compliance. Harvest Vinccler began the year with average oil production of 29,000 barrels of oil per day, and is currently averaging about 21,000 per day. This decline is due to PDVSA's curtailmentall or part of our oil deliveries and the fact that Harvest Vinccler has not been allowed to carry out its drilling program. Due to these factors, in June 2005 we announced that we were withdrawing operational and financial guidance for 2005. Production will continue to decline until drilling is resumed and PDVSA lifts restrictions on deliveries. Collectively, the actions by PDVSA, MEP and the SENIAT, both actual and threatened, are having a material adverse effect on our financial condition, results of operations and cash flows. The situation in Venezuela is also increasing the risk that we will be unable to fund and obtain financing for current operations, as well as growth opportunities. The situation in Venezuela also may have a material adverse effect on our oil and gas reserves. The income tax increase and limit on fees paid to Harvest Vinccler could cause some of the planned future investments to become uneconomic.Venezuelan interests.

In ~~addition, there is uncertainty as to our ability to carry out our development program. These factors create a risk of a downward revision to our proved undeveloped reserves. As reported in~~ our Annual Report on Form 10-K for the year ended ~~2004, approximately 42 percent~~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 ~~oil reserves and 51 percent of gas reserves were classified as proved undeveloped reserves. The situation in Venezuela also may have a material adverse effect~~any tax assessment for the 2005 tax year, it will likely do so on ~~our proved oil and gas reserves. 14~~ ~~In July 2005, as a result~~the common elements of the ~~actions taken by PDVSA, MEP and~~tax assessment, including the SENIAT, we delivered formal notices to Venezuelan government officials of an investment dispute under Venezuelan law and 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 ("ICSID") under the auspices of the World Bank. While we remain committed to reaching mutual agreement with the government of Venezuela to preserve the value of our investment, it may be necessary to submit the matter to arbitration. If initiated, an ICSID proceeding may take a number of years to conclude, and we can provide no assurances as to the outcome. Without waiver of its rights,tax rate. Harvest Vinccler has ~~exchanged proposals and continues discussions~~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 ~~PDVSA and MEP to establish a path forward for converting~~ the ~~OSA to a mixed company under the OHL and~~SENIAT to resolve all claims, including any that would relate to 2005.

Investment income and other increased due to higher interest rates earned on higher average cash balances.

Depletion and amortization expense per Boe produced during the second quarter 2005 was $2.99 versus $2.41 in the second quarter of 2004. The increase was primarily due to increased future development costs. General and administrative expense increased due the annual issuance of restricted stock, additional audit fees, consulting and legal fees related to our business development activities. Taxes other than on income increased due to increased Venezuelan municipal taxes which result from higher oil revenues and an increase in the municipal tax rate in Uracoa. The effective tax rate declined in the second quarter 2005 to 38 percent from 45 percent in 2004 primarily due to higher Venezuelan pre-tax revenue in the second quarter 2005 and the elimination of corporate interest expense due to the November 1, 2004 redemption of 2007 Notes. Our tax calculations do not include the tax increases recently announced by the SENIAT (see Item 2. Venezuela). 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 between Bolivars and U.S. Dollars in March 2005 from 1,920 Bolivars to 2,150 Bolivars to the U.S. Dollar. There has been no change in the official exchange rate since that time. There are many factors affecting foreign exchange rates and resulting exchange gains and losses, 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. PDVSA ~~remitted 50~~is currently remitting 25 percent of the ~~first quarter~~quarterly oil service fees in Bolivars. Due to currency control regulations, it may not be possible to convert excess Bolivars into U.S. Dollars or other foreign currencies. Continued substantial payment by PDVSA in Bolivars or the inability to convert the Bolivars into U.S. Dollars could have a material adverse effect on 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 many local transactions in Venezuela are conducted in local 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 The situation in Venezuela is adversely affecting our cash flow~~

Item 3. Quantitative and may affect our ability to fund execution of our business plan. Our business plan is based upon projections of prices, production levels, and our assumptions that we will be allowed to carry out our program on acceptable terms, that there will be no disruptions or limitations on our production, that PDVSA will pay our invoices timely and in U.S. Dollars and that our cash reserves are adequate. These expectations and assumptions are subject to significant current risk due to the actual and threatened actions of the Venezuelan government (see Item 2. Venezuela). Such actions could also negatively impact the carrying value of certain assets on our balance sheet. In the normal course of our business, our 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. 18 ~~ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK~~Qualitative Disclosures About Market Risk

We are exposed to market risk from ~~the~~ 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, and our Quarterly~~2005. The information about market risk for the first quarter 2006 does not differ materially from that discussed in the Annual Report on Form ~~10-Q~~10-K for the ~~period~~year ended ~~March 31, 2005, as well as in~~ 2005.

~~Item ~~2. Venezuela. 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.

Based on their evaluation as of ~~June 30, 2005,~~March 31, 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. 19~~ forms and 2) accumulated and communicated to our management, including our principal executive and principal financial officers, to allow timely decisions regarding required disclosure.

The SENIAT Tax ~~Assessment.~~Assessment. 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. ~~We are~~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 ~~process~~SENIAT contesting all other claims. While the SENIAT has not notified Harvest Vinccler of ~~reviewing~~any tax assessment for the 2005 tax year, it will likely do so on the common elements of the tax assessment, ~~but~~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 reported under Item 2 Venezuela above, as a result of the actions taken by PDVSA, MEP and the SENIAT, in July 2005, we delivered formal notices to Venezuelan government officials of an investment dispute under Venezuelan law and investment treaties entered into by the government of Venezuela. The bilateral investment treaties and Venezuelan law provide for international arbitration of investment disputes conducted under the auspices of the World Bank. ITEM 2.

~~Item 1A. Risk Factors~~

On March 31, ~~2005:~~ 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.
