Executive Officer, elected to pay withholding tax on a 2002 restricted stock
grant on a cashless basis. This resulted in 5,497 shares being held as treasury
stock at cost.

See accompanying notes to consolidated financial statements.

HARVEST NATURAL RESOURCES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2006 AND 2005 (UNAUDITED)

NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INTERIM REPORTING

In our opinion, the accompanying unaudited consolidated financial
statements contain all adjustments necessary to present fairly the financial
position as of September 30, 2006, and the results of operations and cash flows
for the three and nine month periods ended September 30, 2006 and 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 generally accepted accounting principles in the United States of America
("GAAP"). 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
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 interim period will not be necessarily
indicative of the results of operations for the entire year. Our activities
under our Operating Service Agreement ("OSA") are reflected under the equity
method of accounting effective April 1, 2006. Since such activities are subject
to the completion of the conversion of the OSA to a mixed company (the "Mixed
Company"), we have not recorded any net earnings from such activities for the
three and six months ended September 30, 2006. See Note 6 - Venezuela.

ORGANIZATION

Harvest Natural Resources, Inc. is engaged in the exploration, development,
production and management of oil and gas properties. We conduct our business
principally in Venezuela through our subsidiary Harvest Vinccler S.C.A.
("Harvest Vinccler") in which we indirectly own an 80-percent interest.

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

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

PROPERTY AND EQUIPMENT

We have historically followed the full cost method of accounting for oil
and natural gas properties with costs accumulated in cost centers on a
country-by-country basis, subject to a cost center ceiling (as defined by the
Securities and Exchange Commission ["SEC"]). We have reclassified our Venezuelan
cost center to Investments in Provisional Equity Affiliate to follow the equity
method of accounting. We have not reported net results for the second and third
quarters of 2006 as the conversion of Harvest Vinccler's OSA to the Mixed
Company has not been finalized. See Note 6 - Venezuela.

Excluded costs at September 30, 2006 and December 31, 2005 consisted of
property acquisition costs in the amount of $2.9 million which were all incurred
prior to 2001. All of the excluded costs at September 30, 2006 and December 31,
2005 relate to the acquisition of Benton Offshore China Company and exploration
related to its WAB-21 property. The ultimate timing of when the costs related to
the acquisition of Benton Offshore China Company will be included in amortizable
costs is uncertain.

REVENUE RECOGNITION

Harvest Vinccler invoiced and was paid by PDVSA Petroleo S.A. ("PPSA"), an
affiliate of Petroleos de Venezuela S.A. ("PDVSA") for the first quarter 2006
delivery of its crude oil and natural gas. However, Harvest

Vinccler recorded deferred revenue of $11.2 million for 2005 and first quarter
2006 deliveries, pending clarification on the calculation of crude prices under
an August 2005 Transitory Agreement (the "Transitory Agreement") between PDVSA
and Harvest Vinccler.

In 2005, the Venezuelan government announced that the operating service
agreements held by Harvest Vinccler and other private companies would cease to
exist in 2006 and that such operators would be required to migrate their
agreements to mixed companies in which the state owned a controlling interest.
On March 31, 2006, Harvest Vinccler, PPSA and Corporacion Venezolana del
Petroleo S.A. ("CVP") entered into a Memorandum of Understanding (the "Original
MOU") to convert its OSA to the Mixed Company subject to certain conditions. As
of September 30, 2006, a number of the conditions have not been met, and the
conversion to the Mixed Company has not been completed. In April 2006, the
Venezuelan National Assembly passed legislation terminating all operating
service agreements and directing the government to take over the operations
carried out by the private companies without prejudice to the incorporation of
mixed companies for that purpose. By taking this action before conversion to the
Mixed Company has been completed, the government of Venezuela has created a
contractual void whereby Harvest Vinccler has no recognized agreement setting
out its rights and obligations within Venezuela. Harvest Vinccler continues in
the day-to-day operations of its properties in Venezuela and continues to incur
expenses in doing so; however, there are no contractual means recognized by
Venezuela to address revenues or costs and expenses during the period prior to
the conversion to the Mixed Company. As a result of this situation, our GAAP
consolidated financial statements for the six months ended September 30, 2006,
do not reflect the net results of our producing operations in Venezuela.
Although the Original MOU provides that 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, this adjustment will not
occur until the conversion is completed. In addition, the Original MOU provides
that upon completion of the conversion, Harvest Vinccler will own 40 percent of
the Mixed Company. Accordingly, the equity method of accounting will be followed
for the Mixed Company to reflect our net 32 percent interest.

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 September 30,
2006, Harvest Vinccler had 40.1 billion Venezuela Bolivars ("Bolivars") which
are shown in the September 30, 2006 financial statements as $18.7 million in
cash and cash equivalents.

RESTRICTED CASH

Restricted cash represents cash and cash equivalents used as collateral for
Harvest Vinccler's line of credit and loan agreements, and is classified as
current or non-current based on the terms of the agreements. See Note 2 -
Long-Term Debt.

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.

DERIVATIVES AND HEDGING

Statement of Financial Accounting Standards No. 133 ("SFAS 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 were
designated as cash flow hedge transactions in which we hedged 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 were
reported in other comprehensive income because the highly effective test was
met, and were reclassified to earnings in the period in which earnings were
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") crude oil put
for 5,000 barrels of oil per day. The put cost was $4.24 per barrel,

or $7.7 million, and had 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 had a strike price of
$44.40 per barrel. Due to the amended pricing structure of the OSA as revised by
the Transitory Agreement for our Venezuelan oil, these two puts had the economic
effect of hedging approximately 21,500 barrels of oil per day for an average of
$17.72 per barrel. These puts qualified under the highly effective test and the
mark-to-market loss at September 30, 2005 was included in other comprehensive
loss.

Accumulated Other Comprehensive Loss consisted of $3.8 million ($2.5
million net of tax) at September 30, 2005, of unrealized losses on our crude oil
puts. Oil sales for the three and nine month periods ended 2005 included losses
of $3.8 million in settlement of the hedges. Deferred net losses recorded in
Accumulated Other Comprehensive Loss at September 30, 2005 were reclassified to
earnings during 2005.

We have not entered into any hedging activities in 2006.

ASSET RETIREMENT LIABILITY

Effective January 1, 2003, we adopted SFAS No. 143, "Accounting for Asset
Retirement Obligations" ("SFAS 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 periods ending September 30, 2006 or
December 31, 2005. Changes in asset retirement obligations during the nine
months ended September 30, 2006 and year ended December 31, 2005 were as
follows:

September 30, 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
Reclassified to provisional equity affiliate (2,153) --
------- ------
Asset retirement obligations end of period $ -- $2,129
======= ======

EARNINGS PER SHARE

Basic earnings per common share ("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 37.3 million and 37.2 million for the
three and nine months ended 2006, respectively, and 37.0 million and 36.9
million for the three and nine months ended 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 39.0 million and 38.8 million for the
three and nine months ended 2006, respectively, and 38.5 million and 38.4
million for the three and nine months ended 2005, respectively.

An aggregate of 1.3 million and 1.5 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 nine
months ended 2006, respectively. An aggregate of 1.9 million and 1.8 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 nine months ended 2005.

STOCK-BASED COMPENSATION

At September 30, 2006, we had a number of 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 2005. Prior to 2003, we accounted for our stock-based
compensation plans under the recognition and measurement provisions of
Accounting Principles Board ("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 No.
123 ("SFAS 123"), Accounting for Stock-Based Compensation as amended by SFAS No.
148 ("SFAS 148"), prospectively to all employee awards granted, modified, or
settled after January 1, 2003. Effective January 1, 2005, we adopted SFAS 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 three and nine months ended
2006 and 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.

respectively.

NEW ACCOUNTING PRONOUNCEMENTS

In September 2006, the Financial Accounting Standards Board ("FASB") issued
SFAS 157 - Fair Value Measurement ("SFAS 157") which establishes a framework for
measuring fair value in generally accepted accounting principles, and expands
disclosures about fair value measurements. Adoption is effective for all
financial statements issued for fiscal years beginning after November 15, 2007,
and interim periods within those fiscal years. Earlier application is
encouraged. We are currently evaluating the effect of SFAS 157 on our
consolidated financial position, results of operations and cash flows.

In September 2006, the FASB issued SFAS 158 - Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans ("SFAS 158") which
improves financial reporting by requiring an employer to recognize the
overfunded or underfunded status of a defined benefit postretirement plan as an
asset or liability in its statement of financial position and to recognize
changes in that funded status in the year in which the changes occur through
comprehensive income. Adoption is effective as of December 31, 2006, for
calendar year corporations with publicly traded equity securities. Earlier
application is encouraged. We do not expect SFAS 158 to have a material effect
on our consolidated financial position, results of operations or cash flows.

In September 2006, the SEC issued Staff Accounting Bulletin No. 108 ("SAB
108") regarding the process of quantifying financial statement misstatements.
SAB 108 addresses the diversity in practice in quantifying financial statement
misstatements and the potential under current practice for the build up of
improper amounts on the balance sheet. The guidance in SAB 108 is not expected
to have a material effect on our consolidated financial position, results of
operations and cash flows.

On September 15, 2006, Harvest Vinccler entered into a short term line of
credit with a Venezuelan bank for 11 billion Bolivars (approximately $5.0
million). The line of credit is due March 19, 2007, and has a fixed interest
rate of 10.5 percent. The line of credit is collateralized by a $5.6 million
deposit in a United States bank to cover the line of credit and accrued
interest. The line of credit will be used to meet short term Bolivar denominated
obligations.

On September 27, 2006, Harvest Vinccler entered into a three year term loan
with a Venezuelan bank for 105 billion Bolivars (approximately $48.8 million).
The first principal payment is due 360 days after the funding date in the amount
of 21 billion Bolivars (approximately $9.8 million), and 21 billion Bolivars
(approximately $9.8 million) every 180 days thereafter. The interest rate for
the first year is fixed at 10.02 percent and will be negotiated for the second
year subject to a maximum of 95 percent of the average interest rate charged by
six major Venezuelan banks. This loan is collateralized by a $40.0 million
deposit in a United States bank. The loan will be used to meet the SENIAT income
tax assessments and related interest.

On October 3, 2006, Harvest Vinccler entered into a term loan with a
Venezuelan bank for 20 billion Bolivars (approximately $9.3 million). The loan
matures in 180 days at a fixed interest rate of 10.02 percent. The loan is
collateralized by a $7.7 million deposit in a United States bank. The loan will
be used to meet the SENIAT income tax assessments and related interest.

NOTE 3 - COMMITMENTS AND CONTINGENCIES

Excel Enterprises L.L.C. vs. Benton Oil & Gas Company, now known as Harvest
Natural Resources, Inc., Chemex, Inc., Benton-Vinccler, C.A., Gale Campbell and
Sheila Campbell in the District Court for Harris County, Texas. This suit was
brought in May 2003 by Excel alleging, among other things, breach of a
consulting agreement between Excel and us, misappropriation of proprietary
information and trade secrets, and fraud. Excel seeks actual and exemplary
damages, injunctive relief and attorneys' fees. In October 2003, the Court
abated the suit pending final judgment of a case pending in Louisiana to which
we are not a party. We dispute Excel's claims and plan to vigorously defend
against them. We are unable to estimate the amount or range of any possible
loss.

Uracoa Municipality Tax 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. In
July 2006, the Uracoa Municipality issued a new assessment seeking to impose an
increase in tax rates for the last quarter of 2005 and the first quarter of
2006. In August 2006, the Uracoa Municipality issued two new assessments,
including

penalties, for second quarter 2006 estimated revenues based on the first quarter
2006 oil and natural gas sales and for supposed errors of Harvest Vinccler as
withholding agent. 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 a 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 a possible loss.

The SENIAT Tax Assessment. In July 2005, the SENIAT, the Venezuelan income
tax authority, issued a preliminary tax assessment to Harvest Vinccler of 202
billion Bolivars, or approximately $94 million, related to 2001 through 2004 tax
years. 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.
During the second quarter 2006, the SENIAT initiated an audit of 2005 tax
payments. In June 2006, the SENIAT announced that if Harvest Vinccler did not
pay the tax claims in 15 days, it would initiate legal proceedings, including
seeking court approval to seize assets. As a result of meetings with the SENIAT,
an agreement in principle was reached which was intended to settle all the
SENIAT tax claims for 2001 through 2004 and provide a basis for final
adjustments to Harvest Vinccler's 2005 and 2006 tax years. As a result of the
agreement in principle, Harvest Vinccler took a charge in the second quarter
2006 of $61 million for the estimated impact of the resolution of these tax
issues. However, in September 2006, the SENIAT issued a final assessment for
2001 through 2004, which did not reflect the settlement in principle and,
instead, sought an additional $13 million in tax and interest from Harvest
Vinccler. In September 2006, Harvest Vinccler paid the SENIAT $34.6 million
which represents the amount of principal under the 2001 through 2004 final
assessment. In October 2006, Harvest Vinccler received an assessment from the
SENIAT for 2005 taxes in the amount of $15.8 million. As a result, Harvest
Vinccler took an additional charge in the third quarter 2006 of $14 million for
the 2001 through 2005 assessments resulting in a net change of $10 million for
the quarter. Harvest Vinccler paid the principal amount of the 2005 assessment
in October 2006 and intends to pay all of the interest before the end of the
year. We continue to believe that Harvest Vinccler has properly paid all of its
taxes, but we understand that resolving the income tax issues with the SENIAT is
a necessary step in the transition of Harvest Vinccler's operations to the Mixed
Company.

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.

NOTE 4 - TAXES

TAXES OTHER THAN ON INCOME

Harvest Vinccler paid municipal taxes through the first quarter 2006 on
operating fee revenues it received under the OSA for deliveries from the South
Monagas Unit. In September 2006, PDVSA remitted to the Uracoa municipality an
additional $1.0 million based on the new tax rates imposed that had been
withheld from Harvest Vinccler's first quarter 2006 oil and natural gas sales.
The components of taxes other than on income were (in thousands):

Venezuela municipal taxes and certain other taxes are not reported for the

NOTE 5 - OPERATING SEGMENTS

We regularly allocate resources to, and assess the performance of our
operations by segments that are organized by unique geographic and operating
characteristics. The segments are organized in order to manage regional
business, currency and tax related risks and opportunities. As a result of the
situation in Venezuela, our GAAP consolidated financial statements for the three
and six months ended September 30, 2006, do not reflect the net results of our
producing operations in Venezuela. See Note 6 - Venezuela. Revenue from
Venezuela is derived primarily from the delivery and sale of oil and natural
gas. Operations included under the heading "United States and Other" include
corporate management, cash management, business development and financing
activities performed in the United States and other countries which do not meet
the requirements for separate disclosure. All intersegment revenues, other
income and equity earnings, expenses and receivables are eliminated in order to
reconcile to consolidated totals. Corporate general and administrative, business
development and interest expenses are included in the United States and Other
segment and are not allocated to other operating segments:

NOTE 6 - VENEZUELA

In 2005, the Venezuelan government announced that the operating services
agreements held by Harvest Vinccler and other private companies would cease to
exist in 2006 and that such operators would be required to migrate their
agreements to mixed companies in which the state owned a controlling interest.
On March 31, 2006, Harvest Vinccler signed the Original MOU with PPSA and CVP to
convert the contractual arrangement governed by the OSA into the Mixed Company
subject to certain conditions, including finalizing an agreement between the
parties for additional consideration to be provided to the Mixed Company. On
August 16, 2006, Harvest Vinccler, PPSA and CVP entered into an amendment to the
Original MOU (the "Amended MOU") that, upon award by the government, provided
for the addition of three fields to the Mixed Company as additional
consideration for our migration from the OSA to the Mixed Company. (Collectively
the Original MOU and the Amended MOU are referred to as the "MOU".) Another
condition in the MOU to completing the conversion to the Mixed Company is

receiving approval by our stockholders. On September 22, 2006, we filed a
Preliminary Proxy Statement with the SEC for the purpose of calling a special
meeting with our stockholders to obtain such approval. There are other
conditions in the MOU to completing the conversion to the Mixed Company, many of
which are largely beyond our control. Although there has been progress since the
MOU was signed, conversion to the Mixed Company has not been completed as of the
end of the third quarter.

In April 2006, the Venezuelan National Assembly passed legislation
terminating all operating service agreements and directing the government to
take over the operations carried out by the private companies without prejudice
to the incorporation of mixed companies for that purpose. By taking this action
before conversion to the Mixed Company has been completed, the government of
Venezuela has created a contractual void whereby Harvest Vinccler has no
recognized agreement setting out its rights and obligations within Venezuela.
Harvest Vinccler continues in the day-to-day operations of its properties in
Venezuela and continues to incur expenses in doing so; however, there are no
contractual means recognized by Venezuela to address revenues or costs and
expenses during the period prior to the conversion to the Mixed Company. As a
result of this situation, our consolidated financial statements prepared in
accordance with GAAP for the quarter ended September 30, 2006, do not reflect
the net results of our producing operations in Venezuela. Although the MOU
provides that 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, this adjustment will not occur and we will not
be able to include the results of our Venezuelan operations in our consolidated
financial statements until the conversion to the Mixed Company is completed. The
timing and certainty of completing the conversion remains unknown. In addition,
the MOU provides that upon completion of the conversion, Harvest Vinccler will
own 40 percent of the Mixed Company. Accordingly, the equity method of
accounting will be followed for the Mixed Company to reflect our net 32 percent
interest.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Harvest Natural Resources, Inc. ("Harvest" or the "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. When used in this report, the words "budget",
"guidance", "forecast", "anticipate", "expect", "believe", "goals", "projects",
"plans", "anticipates", "estimates", "should", "could", "assume" and similar
expressions are intended to identify forward-looking statements. 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 reserves, conversion of
Venezuelan assets to the Mixed Company, 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 gas properties, risks
incumbent to being a minority stockholder in a corporation, 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 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 2005, which includes certain
definitions and a summary of significant accounting policies and should be read
in conjunction with this Quarterly Report.

VENEZUELA

In our Annual Report on Form 10-K for the year ended 2005 and our Quarterly
Report on Form 10-Q for the quarterly periods ended March 31, 2006 and June 30,
2006, we described the events in Venezuela that have adversely affected our
operations and profitability. See Item 1 Business, Item 1A Risk Factors and Item
7 Management's Discussion and Analysis of Financial Condition and Results of
Operations in our Annual Report on Form 10-K for the year ended 2005 and Item 2
Management's Discussion and Analysis of Financial Condition and Results of
Operations and Item 1A Risk Factors in our Quarterly Report on Form 10-Q for the
quarterly periods ended March 31, 2006 and June 30, 2006, for a complete
description of these matters.

On March 31, 2006, Harvest Vinccler signed a Memorandum of Understanding
(the "Original MOU") with PDVSA Petroleo, S.A. ("PPSA") and Corporacion
Venezolana del Petroleo S.A. ("CVP") to convert the contractual arrangement
governed by the Operating Service Agreement ("OSA") into a mixed company (the
"Mixed Company") subject to certain conditions, including finalizing an
agreement between the parties for additional consideration to be provided to the
Mixed Company. On August 16, 2006, Harvest Vinccler, PPSA and CVP entered into
an amendment to the Original MOU (the "Amended MOU") that, upon award by the
government, provided for the addition of three fields to the Mixed Company as
additional consideration for our migration from the OSA to the Mixed Company.
The three fields are the Isleno, Temblador and El Salto fields. (Collectively
the Original MOU and the Amended MOU are referred to as the "MOU".) Another
condition to completing the conversion to the Mixed Company is that the
transaction must be approved by our stockholders. On September 22, 2006, we
filed a Preliminary Proxy Statement with the Securities and Exchange Commission
("SEC") for the purpose of calling a special meeting of our stockholders to
obtain such approval. We intend to send definitive proxy materials to our
stockholders as soon as possible and to hold a meeting for such approval in
December 2006. There are other conditions in the MOU to completing the
conversion to the Mixed Company, most of which are beyond our control. These
conditions include approval by the Venezuelan Ministry of Energy and Petroleum
("MEP") and the Venezuelan National Assembly; obtaining or filing all necessary
consents, authorizations, orders or approvals of governmental authorities;
making all necessary filings or registrations with governmental authorities and
giving all requisite notifications to governmental authorities; completion of
the Conversion Contract and all annexes, including the business plan; and the
award of the three additional fields to the Mixed Company by the Venezuelan
government. Even if our stockholders approve the proposed Transaction, there can
be no assurance that the other conditions to closing will be met and that the
conversion of the OSA to the Mixed Company will be completed. Until there is
clarity and resolution, uncertainty over the future of our investment in
Venezuela will continue to affect our performance.

As we discussed in our Quarterly Report on Form 10-Q for the quarter ended
June 30, 2006, in April 2006, the Venezuelan National Assembly passed
legislation terminating all operating service agreements and directing the
government to take over the operations carried out by the private companies
without prejudice to the incorporation of mixed companies for that purpose. Even
though it is our position that the OSA is still in place, as a result of actions
by the government of Venezuela, Harvest Vinccler currently has no recognized
agreement setting out its rights and obligations within Venezuela. Harvest
Vinccler continues in the day-to-day operations of its properties in Venezuela
and continues to incur expenses in doing so; however, there are no contractual
means recognized by Venezuela to address revenues or costs and expenses during
the period prior to the conversion to the Mixed Company. As a result of this
situation, our consolidated financial statements prepared in accordance with
generally accepted accounting principals ("GAAP") for the quarter ended
September 30, 2006, do not reflect the net results of our producing operations
in Venezuela. We will not be able to include the results of our Venezuelan
operations in our consolidated financial statements until the conversion to the
Mixed Company is completed. Although the MOU provides that 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,
this adjustment will not occur until the conversion is completed. The timing for
completing the conversion to the Mixed Company is uncertain. In addition, the
MOU provides that upon completion of the conversion, Harvest Vinccler will own
40 percent of the Mixed Company. Accordingly, the equity method of accounting
will be followed for the Mixed Company to reflect our net 32 percent interest.
We will no longer be able to consolidate our Venezuelan interest as of April 1,
2006, and will be required to reflect the equity income (or loss) as a separate
line in the future Consolidated Statements of Operations.

Certain operating statistics for the three and six month periods ended
September 30, 2006, for the South Monagas Unit operated by Harvest Vinccler are
set forth below. This information is provided at 100 percent, without reduction
for our interest under the OSA or our ownership interest in the Mixed Company.
While we believe this information to be accurate, no representation is made with
respect to what will be reflected in our consolidated financial statements after
completing the conversion to the Mixed Company. This information may not be
representative of future results.

Barrels of oil equivalent 2.4 4.9

Capital expenditures ($millions) 0.2 0.5

Crude oil prices that would be paid for the oil production if the
conversion contract were in place cannot be calculated as several elements of
the pricing formula have not been set. Market prices for crude oil of the type
produced in the fields operated by Harvest Vinccler averaged approximately
$50.00 a barrel for the three and six months ended September 30, 2006,
respectively. The price for natural gas that would be paid under the conversion
contract is $1.54 per thousand cubic feet.

In our Quarterly Report on Form 10-Q for the quarter ended June 30, 2006,
we provided an update on the preliminary tax assessment issued by the SENIAT for
2001 through 2004 tax years. We described the agreement in principle reached
with the SENIAT to settle all tax claims for 2001 through 2004 and provide a
basis for final adjustments to Harvest Vinccler's 2005 and 2006 tax years. As a
result of the agreement in principle, Harvest Vinccler took a charge in the
second quarter 2006 of $61 million for the estimated impact of the resolution of
these tax issues. However, in September 2006, the SENIAT issued a final
assessment for 2001 through 2004, which did not reflect the settlement in
principle and, instead, sought an additional $13 million in tax and interest
from Harvest Vinccler. In September 2006, Harvest Vinccler paid the SENIAT $34.6
million which represents the amount of principal under the 2001 through 2004
final assessment. In October 2006, Harvest Vinccler received an assessment from
the SENIAT for 2005 taxes in the amount of $15.8 million. As a result, Harvest
Vinccler took an additional charge in the third quarter 2006 of $14 million for
the 2001 through 2005 assessments resulting in a net change of $10 million for
the quarter. Harvest Vinccler paid the principal amount of the 2005 assessment
in October 2006 and intends to pay all of the interest before the end of the
year. We continue to believe that Harvest Vinccler has properly paid all of its
taxes, but we understand that resolving the income tax issues with the SENIAT is
a necessary step in the transition of Harvest Vinccler's operations to the Mixed
Company. In September 2006, Harvest Vinccler entered into a loan agreement with
a

Venezuelan bank for 105 billion Venezuelan Bolivars ("Bolivars") (approximately
$48.8 million), and in October 2006, Harvest Vinccler entered into a second loan
agreement with the same bank for 20 billion Bolivars (approximately $9.3
million). Harvest Vinccler collateralized the loans with deposits totaling $47.7
million in a bank in the United States ($7.7 million was deposited on October 3,
2006). The proceeds of the loans will be used in making tax and interest
payments to the SENIAT.

Since signing the MOU, the governance of the operations of Harvest
Vinccler's properties has been influenced by a transitory committee consisting
of three appointees by CVP and two appointees by Harvest Vinccler. In addition,
CVP has designated a General Manager and President for the Mixed Company, both
of whom influence Harvest Vinccler's operations and staffing. The transitory
committee has finished its task upon these designations. Harvest Vinccler
continues to substantially control operations of its properties maintaining
interaction with the designated CVP representatives.

In our Annual Report on Form 10-K for the year ended 2005, we discussed our
reported quantities of proved oil and gas reserves in the context of the
situation in Venezuela. We noted that under SEC standards for reporting
reserves, proved reserves are estimated quantities of oil and gas which data
demonstrates with reasonable certainty to be recoverable in future years from
known reservoirs under existing economic and operating conditions. Under this
standard, we reduced our year-end quantities of proved reserves for 2005 because
the actions taken by the Venezuelan government created uncertainty as to whether
those reserves could be recovered under the economic and operating conditions
then existing in Venezuela. This situation is exacerbated by the lack of a
recognized contract covering our operations in Venezuela today, and until we
complete the conversion to the Mixed Company, we will not have reserves to
report under SEC standards. Assuming completion of the conversion to the Mixed
Company, we will report our net 32 percent of the Mixed Company's proved
reserves. This will include the quantities of proved reserves attributable to
the three fields to be added to the Mixed Company as provided in the Amended
MOU. Harvest Vinccler has contracted with an independent petroleum engineering
firm to evaluate the proved oil and natural gas reserves attributable to the
South Monagas Unit and the three additional fields upon conversion to the Mixed
Company.

Several conversion agreements respecting a number of the mixed companies
have been finalized and are awaiting approval from the MEP and the Venezuelan
National Assembly. We remain committed to finalizing the conversion to the Mixed
Company at the earliest possible date. However, we are concerned about the time
it is taking to complete the process, with the resulting growing financial
exposure and the effect on operations and production. We continue to assess and
consider alternatives for preserving value, including a possible sale or
exchange of our interests in Venezuela. The alternatives available to us are
limited and subject to a number of significant variables, including timing for
the completion of conversion to the Mixed Company, the value to us of the Mixed
Company assets, governmental approvals and any tax consequences. For additional
discussion of the risks associated with our operations in Venezuela, see Item 1A
Risk Factors.

CAPITAL RESOURCES AND LIQUIDITY

Debt Reduction. We have paid the final quarterly principal and interest
obligations of $1.3 million on the Harvest Vinccler variable rate loan.

Working Capital. The net funds raised and/or used in each of the operating,
investing and financing activities are summarized in the following table and
discussed in further detail below:

Net cash provided by (used in) financing activities 49,244 (5,305)
-------- --------
Net increase in cash $ 18,295 $ 57,405
======== ========

At September 30, 2006, we had current assets of $224.0 million and current
liabilities of $91.9 million, resulting in working capital of $132.1 million and
a current ratio of 2.4:1. This compares with a working capital of $178.1 million
and a current ratio of 3.9:1 at December 31, 2005. The decrease in working
capital of $46.0 million was

primarily due to the inability to reflect the net results of our producing
operations in Venezuela in our consolidated financial statements for the quarter
ended September 30, 2006 and the charge in the third quarter 2006 of $14.0
million for additional taxes and related interest for the estimated impact of
income tax assessments by the SENIAT for 2001 through 2005. See Item 2.
Management's Discussion and Analysis of Financial Condition and Results of
Operations, Venezuela. We recognize the need to diversify our asset base and
that is the primary focus of our strategy. Harvest Natural Resources, Inc. and
subsidiaries have over $181 million of cash and are not reliant in the interim
on cash distributions from Venezuela to meet current corporate, business
development and limited operational needs.

Cash Flow from Operating Activities. During the nine months ended 2006 and
2005, net cash provided by operating activities was $15.7 million and $78.6
million, respectively. The $62.9 million decrease was primarily due to the
collection of the first quarter accrued oil and gas sales receivable which was
offset by the charge in the second and third quarters for the estimated tax
assessments and related interest.

Cash Flow from Investing Activities. During the nine months ended 2006, we
had limited drilling and production-related expenditures, and we deposited $45.6
million restricted cash as collateral to two loans with a Venezuelan bank (see
Item 2 Management's Discussion and Analysis of Financial Condition and Results
of Operations). During the nine months ended 2005, we had drilling and
production-related capital expenditures of approximately $15.8 million and no
restricted cash. The decrease in capital expenditures is due to the continued
suspension of our drilling program and the fact that the conversion of the OSA
to the Mixed Company has not been finalized. The increase in restricted cash is
collateral for the new borrowings to pay the assessments received from the
SENIAT and other short-term Bolivar denominated obligations. We continue to
expend funds on behalf of the Mixed Company for workovers and maintenance of the
existing wells. Our remaining worldwide capital commitments support our business
development efforts, are relatively minimal and are substantially at our
discretion.

Cash Flow from Financing Activities. During the nine months ended 2006,
Harvest Vinccler borrowed 11 billion Bolivars (approximately $5.0 million) for
short term Bolivar denominated obligations and 105 billion Bolivars
(approximately $48.8 million) for the SENIAT income tax assessments and related
interest. During the nine months ended 2006, Harvest Vinccler repaid $5.5
million of its U. S. Dollar debt (one payment of $0.3 million and four payments
of $1.3 million on the variable rate loans). During the nine months ended 2005,
Harvest Vinccler repaid $6.1 million of its U.S. dollar debt (three payments of
$0.3 million and four payments of $1.3 million on the variable rate loans).

RESULTS OF OPERATIONS

You should read the following discussion of the results of operations for
the three and nine months ended 2006 and 2005 and the financial condition as of
September 30, 2006 and December 31, 2005 in conjunction with our consolidated
financial statements and related notes included in our Annual Report on Form
10-K for the year ended 2005. Each of the comparative periods reflects our
inability to report the results of Harvest Vinccler as the conversion of the OSA
to the Mixed Company has not been finalized.

THREE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED WITH THREE MONTHS ENDED SEPTEMBER
30, 2005 (IN MILLIONS)

We reported a net loss of $13.6 million, or $0.36 diluted earnings per
share, in the third quarter 2006 compared with net income of $8.1 million, or
$0.21 diluted earnings per share, in the third quarter of 2005.

Total expenses and other non-operating (income) expense:

Interest expense 5.1 2.8 2.3 82

===== ===== ===== ====

General and administrative expenses decreased due to lower business
development costs. Taxes other than on income decreased due to the elimination
of municipal taxes as a result of the conversion of the OSA to the Mixed
Company. However, in September 2006, PDVSA remitted to the Uracoa Municipality
$1.0 million that had been withheld from Harvest Vinccler's first quarter 2006
oil and natural gas sales. Interest expense increased due to Harvest Vinccler's
estimated liability for interest on the tax assessments. See Item 2. Managements
Discussion and Analysis of Financial Condition and Results of Operations,
Venezuela.

Income tax expense increased $9.4 million related to an additional charge
in the third quarter for the difference in Harvest Vinccler's estimated tax
settlements recorded in the second quarter 2006 and the final tax assessments,
partially offset by a $4.0 million credit resulting from future benefits under
the Venezuelan tax system. See Item 2. Managements Discussion and Analysis of
Financial Condition and Results of Operations, Venezuela.

NINE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED WITH NINE MONTHS ENDED SEPTEMBER
30, 2005 (IN MILLIONS)

We reported a net loss of $50.0 million, or $1.34 diluted earnings per

or $1.05 diluted earnings per share, in the nine months ended 2005.

General and administrative expenses increased due to higher business
development costs and employee related expenses. Taxes other than on income
decreased due to the elimination of municipal taxes as a result of the
conversion of the OSA to the Mixed Company. However, in September 2006, PDVSA
remitted to the Uracoa Municipality $1.0 million that had been withheld from

EFFECTS OF CHANGING PRICES, FOREIGN EXCHANGE RATES AND INFLATION

Our results of operations and cash flow can be affected by changing oil
prices. However, the affect, if any, of changing oil prices will not be
reflected in our results until we complete the conversion of the OSA to the
Mixed Company.

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
controls. After conversion to the Mixed Company, natural gas sales will be paid
in Bolivars.

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. Upon
the conversion to the Mixed Company, Harvest Vinccler is to receive
distributions in U.S. Dollars. In the interim, Harvest Vinccler has borrowed 105
billion Bolivars (approximately $48.8 million) from a Venezuelan bank in order
to meet its Venezuela income tax assessments and related interest and 11 billion
Bolivars (approximately $5 million) to meet its short term Bolivar denominated
obligations. The loans are collateralized with U.S. Dollar deposits in the
United States. Harvest Vinccler anticipates that inflation could continue to
increase in Venezuela and that inflation could result in the further weakening
of the Bolivar to the U.S. Dollar.

ITEM 3. QUANTITATIVE AND 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 prices, interest rates, foreign exchange
and political risk, as discussed in our Annual Report on Form 10-K for the year
ended 2005 and our Quarterly Report on Form 10-Q for the quarters ended March
31, 2006 and June 30, 2006.

ITEM 4. CONTROLS AND PROCEDURES

The SEC, 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 quarterly and annual reports under the Securities
Exchange Act of 1934 (the "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 Rule 13a-15(f) 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. 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 September 30, 2006, our principal executive
officer and principal financial officer have concluded that our disclosure
controls and procedures (as defined in Rule 13a-15(e) 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 SEC's rules and forms and 2) accumulated and communicated to
our management, including our principal executive and principal financial
officers, to allow timely decisions regarding required disclosure.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See our Annual Report on Form 10-K for the year ended 2005 and our
Quarterly Report on Form 10-Q for the quarterly periods ended March 31, 2006 and
June 30, 2006, for a description of certain other legal proceedings. There have
been no material developments in such legal proceedings since the filing of such
reports.

ITEM 1A. RISK FACTORS

In our Quarterly Report on Form 10-Q for the quarterly period ended June
30, 2006, we described the actions of the Venezuelan government which have left
Harvest Vinccler with no recognized agreement setting out its rights and
obligations within Venezuela. While Harvest Vinccler continues in the day-to-day
operations of its properties in Venezuela and continues to incur expenses in
doing so, there are no contractual means recognized by Venezuela to address
revenues or costs and expenses during the period prior to the conversion to the
Mixed Company. This situation, which started with the second quarter of 2006,
continues to persist, with the result that our consolidated financial statements
prepared in accordance with GAAP for the quarter ended September 30, 2006, do
not reflect the net results of our producing operations in Venezuela. We will
not be able to include the results of our Venezuelan operations in our
consolidated financial statements until the conversion to the Mixed Company is
completed. Although the MOU provides that 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, this adjustment
will not occur until the conversion is completed. The timing for completing the
conversion to the Mixed Company is uncertain. In addition, the MOU provides that
upon completion of the conversion, Harvest Vinccler will own 40 percent of the
Mixed Company. Accordingly, the equity method of accounting will be followed for
the Mixed Company to reflect our net 32 percent interest. We will no longer be
able to consolidate our

Venezuelan interest as of April 1, 2006, and will be required to reflect the
equity income (or loss) as a separate line in the future Consolidated Statements
of Operations.

In addition to the risks described in our Annual Report on Form 10-K for
the year ended 2005 and our Quarterly Report on Form 10-Q for the quarterly
periods ended March 31, 2006 and June 30, 2006, the timing and outcome risks
associated with completing the conversion to the Mixed Company include:

- While we continue to maintain substantial cash reserves, our
operations in Venezuela represent our only source of revenues, and the
funds available to pursue our growth strategy may be adversely
affected by the financial demands of continued operations in Venezuela
during the conversion process.

- If we are unable to complete the conversion to the Mixed Company, we
believe the Venezuelan government will seize our assets and take over
Harvest Vinccler's operations. Our recourse will be to pursue claims
for expropriation of our interests or similar claims against the
Venezuelan government. An arbitration proceeding may take a number of
years to conclude and we can provide no assurances as to outcome.

- Pursuant to the MOU, CVP has agreed to make an economic adjustment to
compensate us so as to achieve the same economic result as if the
conversion had been completed on April 1, 2006. This adjustment is to
occur once the conversion is completed. However, there are no
assurances that CVP and PPSA will have adequate funds to make payment
to us for the period dating back to April 1, 2006.

- There is no assurance that the government will award the three fields
contemplated by the Amended MOU.

- Our stockholders may not approve the conversion to the Mixed Company.
If the conversion to the Mixed Company is not approved, we believe the
Venezuelan government will seize our assets and take over Harvest
Vinccler's operations. Our recourse will be to pursue claims against
the Venezuelan government for expropriation of our interest or similar
actions.

- We are continuing to look at alternatives to diversify our assets.
However, the alternatives are limited. If the conversion to the Mixed
Company is completed, and we decide to enter into a sale or exchange
of all or part of our assets with an unrelated third party, the third
party must be approved by the Venezuelan government. The number of
potential buyers that will be acceptable to the Venezuelan government
is limited and this number of potential buyers may be further affected
and limited by country risk concerns. Further, a sale or exchange of
all or part of our assets after completing the conversion to the Mixed
Company may be subject to U.S. tax consequences.

- The actions of CVP, through its members to the transitory committee,
its appointed General Manager or President to the Mixed Company, may
adversely affect our ability to conduct operations and retain key
personnel.

See our Annual Report on Form 10-K for the year ended 2005 under Item 1A
Risk Factors for a description of other risk factors.
