FACTORS AFFECTING FORWARD LOOKING STATEMENTS

This Annual Report on Form 10-K contains certain "forward looking
statements" within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
Specifically, all statements under the captions "Item 1 and 2 -- Business and
Properties" and "Item 7 -- Management's Discussion and Analysis of Financial
Condition and Results of Operations" relating to capital expenditures and
investments related to environmental compliance and strategic planning,
purchasing patterns of refined products and capital resources available to the
Company (as defined herein) are forward looking statements. In addition, when
used in this document, the words "anticipate," "estimate," "prospect" and
similar expressions are used to identify forward looking statements. Such
statements are subject to certain risks and uncertainties, such as increased
inflation, continued access to capital markets and commercial bank financing on
favorable terms, increases in regulatory burdens, changes in prices or demand
for the Company's products as a result of competitive actions or economic
factors and changes in the cost of crude oil, feedstocks, blending components or
refined products. Such statements are also subject to the risks of increased
costs in related technologies and such technologies producing anticipated
results. Should one or more of these risks or uncertainties, among others,
materialize, actual results may vary materially from those estimated,
anticipated or projected. Although CITGO believes that the expectations
reflected by such forward looking statements are reasonable based on information
currently available to the Company, no assurances can be given that such
expectations will prove to have been correct.

PART I

ITEMS 1. AND 2. BUSINESS AND PROPERTIES

OVERVIEW

CITGO Petroleum Corporation ("CITGO" or the "Company") is a direct
wholly-owned operating subsidiary of PDV America, Inc. ("PDV America"), a
wholly-owned subsidiary of PDV Holding, Inc. The Company's ultimate parent is
Petroleos de Venezuela, S.A. ("PDVSA", which may also be used herein to refer to
one or more of its subsidiaries), the national oil company of the Republic of
Venezuela. CITGO and its subsidiaries are engaged in the refining, marketing and
transportation of petroleum products including gasoline, diesel fuel, jet fuel,
petrochemicals, lubricants, asphalt and refined waxes, mainly within the
continental United States east of the Rocky Mountains.

CITGO's transportation fuel customers include CITGO branded wholesale
marketers, convenience stores and airlines. Asphalt is generally marketed to
independent paving contractors on the East Coast of the United States.
Lubricants are sold to independent marketers, mass marketers and industrial
customers, and petrochemical feedstocks and industrial products are sold to
various manufacturers and industrial companies throughout the United States.
Petroleum coke is sold primarily in international markets.

COMPETITIVE NATURE OF THE PETROLEUM REFINING BUSINESS

The petroleum refining industry is cyclical and highly volatile, reflecting
capital intensity with high fixed and low variable costs. Petroleum industry
operations and profitability are influenced by a large number of factors, over
some of which individual petroleum refining and marketing companies have little
control. Governmental regulations and policies, particularly in the areas of
taxation, energy and the environment, have a significant impact on petroleum
activities, regulating how companies conduct their operations and formulate
their products. The U.S. petroleum refining industry has entered a period of
consolidation in which a number of former competitors have combined their
operations. Demand for crude oil and its products is largely driven by the
health of local and worldwide economies, although weather patterns and taxation
relative to other energy sources also play significant parts. Generally, U.S.
refiners compete for sales on the basis of price and brand image and, in some
areas, product quality.

CITGO produces its light fuels and petrochemicals primarily through its
Lake Charles and Corpus Christi refineries. Asphalt refining operations are
carried out through CITGO's Paulsboro and Savannah refineries. CITGO also owns
an interest in and obtains refined products from a refinery in Houston.

Lake Charles, Louisiana Refinery. This refinery was originally built in
1944 and since then has been continuously upgraded. Today it is a modern,
complex, high conversion refinery, which is one of the largest in the United
States. It has a rated refining capacity of 320 MBPD and is capable of
processing large volumes of heavy crude oil into a flexible slate of refined
products, including significant quantities of high-octane unleaded gasoline and
reformulated gasoline. The Lake Charles refinery has a Solomon Process
Complexity Factor of 17.0 (as compared to an average of 13.8 for U.S. refineries
in the most recently available Solomon Associates, Inc. survey). The Solomon
Process Complexity Rating is an industry measure of a refinery's ability to
produce higher value-added products. A higher rating indicates a greater
capability to produce such products.

Approximately 66%, 63% and 67% of the total crude runs at the Lake Charles
refinery, in the years 1998, 1997 and 1996, respectively, consisted of crude oil
with an average API gravity of 24 degrees or less. Due to the complex processing
required to refine such crude oil, the Lake Charles refinery's economic crude
oil throughput capacity is approximately 290 MBPD, which is approximately 90% of
its rated capacity of 320 MBPD.

The Lake Charles refinery's Gulf Coast location provides it with access to
crude oil deliveries from multiple sources. Imported crude oil and feedstock
supplies are delivered by ship directly to the Lake Charles refinery, and
domestic crude oil supplies are delivered by pipeline and barge. In addition,
the refinery is connected by pipelines to the Louisiana Offshore Oil Port and to
terminal facilities in the Houston area through which it can receive crude oil
deliveries if the Lake Charles docks are temporarily inaccessible. For delivery
of refined products, the refinery is connected through the Lake Charles Pipeline
directly to the Colonial and Explorer Pipelines, which are the major refined
product pipelines supplying the northeast and midwest regions of the United
States, respectively. The refinery also uses adjacent terminals and docks, which
provide access for ocean tankers and barges.

The Lake Charles refinery's main petrochemical products are propylene and
benzene. Industrial products include sulphur, residual fuels and petroleum coke.

Located adjacent to the Lake Charles refinery is a lubricants refinery
operated by CITGO and owned by Cit-Con Oil Corporation ("Cit-Con"), which is
owned 65% by CITGO and 35% by Conoco, Inc. ("Conoco"). Primarily because of its
specific design, the Cit-Con refinery produces extremely high quality oils and
waxes, and is one of the few in the industry designed as a stand-alone
lubricants refinery. Feedstocks are supplied 65% from CITGO's Lake Charles
refinery and 35% from Conoco's nearby refinery. Finished refined products are
shared on the same pro rata basis by CITGO and Conoco.

Corpus Christi, Texas Refinery. This refinery complex consists of the East
and West Plants, located within five miles of each other. Construction began on
the East Plant in 1937, and it was extensively reconstructed and modernized
during the 1970's and 1980's. The West plant was completed in 1983. The Corpus
Christi refinery is an efficient and highly complex facility, capable of
processing high volumes of heavy crude oil into a flexible slate of refined
products, with a Solomon Process Complexity Factor of 20.5 (as

compared to an average 13.8 for U.S. refineries in the most recently available
Solomon Associates, Inc. survey).

The following table shows rated refining capacity, refinery input and

(1) At year end.

Corpus Christi crude runs during 1998 consisted of 100% heavy sour
Venezuelan crude. The average API gravity of the composite crude slate run at
the Corpus Christi refinery is approximately 24 degrees. Crude oil supplies are
delivered directly to the Corpus Christi refinery through the Port of Corpus
Christi.

CITGO operates the West plant under a sublease agreement (the "Sublease")
from Union Pacific Corporation ("Union Pacific"). The basic term of the Sublease
ends on January 1, 2004, but CITGO may renew the Sublease for successive renewal
terms through January 31, 2011. CITGO has the right to purchase the West Plant
from Union Pacific at the end of the basic term, the end of any renewal term, or
on January 31, 2011 at a nominal price.

During the last several years, CITGO has increased the capacity of the
Corpus Christi refinery to produce petrochemical products. The Corpus Christi
refinery's main petrochemical products include cumene, cyclohexane, methyl
tertiary butyl ether ("MTBE") and aromatics (including benzene, toluene, and
xylene). The Company produces a significant quantity of cumene, an important
petrochemical product used in the engineered plastics market. The production of
xylene, a basic building block used in the manufacture of consumer plastics,
allows the refinery to take advantage of its reforming capacity while staying
within the gasoline specifications of the Clean Air Act Amendments of 1990.

Paulsboro, New Jersey Refinery. This is an asphalt refinery, which consists
of Unit I, with a rated capacity of 44 MBPD, and Unit II, with a rated capacity
of 40 MBPD. Unit I was constructed in 1979 primarily to process low sulphur,
light crude oil but has been modified to run heavier crudes. Unit II, originally
constructed in 1980 to produce asphalt from high sulphur, heavy crude oil high
in naphthenic acid, is a combination atmospheric and vacuum distillation
facility.

Savannah, Georgia Refinery. This is an asphalt refinery, which includes two
crude distillation units, with a combined rated capacity of 28 MBPD.

LYONDELL-CITGO Refining LP. On July 1, 1993, subsidiaries of CITGO and
Lyondell Chemical Company ("Lyondell") formed LYONDELL-CITGO Refining LP
("LYONDELL-CITGO"), which
8
9

owns and operates a sophisticated 265 MBPD refinery previously owned by Lyondell
and located on the ship channel in Houston, Texas. At December 31, 1998, CITGO's
investment in LYONDELL-CITGO was $597 million. In addition, at December 31,
1998, CITGO held notes receivable from LYONDELL-CITGO of $36 million. (See
Consolidated Financial Statements of CITGO -- Note 3 in Item 14a). The crude oil
processed by this refinery is supplied by PDVSA under a long-term crude oil
supply agreement through the year 2017. CITGO purchases substantially all of the
refined products produced at this refinery under a long-term contract. (See
Consolidated Financial Statements of CITGO -- Notes 3 and 4 in Item 14a).

CITGO's participation interest in LYONDELL-CITGO was approximately 41% at
December 31, 1998. CITGO has a one-time option, exercisable after January 1,
2000 but not later than September 30, 2000, to increase, for an additional
investment, its participation interest to 50%.

CRUDE OIL AND REFINED PRODUCT PURCHASES

CITGO owns no crude oil reserves or production facilities, and must
therefore rely on purchases of crude oil and feedstocks for its refinery
operations. In addition, because CITGO's refinery operations do not produce
sufficient refined products to meet the demands of its branded marketers, CITGO
purchases refined products, primarily gasoline, from other refiners, including
LYONDELL-CITGO, PDV Midwest Refining, L.L.C. ("PDVMR"), Chalmette Refining,
L.L.C. ("Chalmette") and a joint venture that owns and operates a refinery in
St. Croix, U.S. Virgin Islands ("HOVENSA"). See "Item 13. Certain Relationships
and Related Transactions".

Crude Oil Purchases. The following chart shows CITGO's purchases of crude

CITGO's largest supplier of crude oil is PDVSA, and CITGO has entered into
long-term crude oil supply agreements with PDVSA with respect to the crude oil
requirements for each of CITGO's refineries. See "Item 13. Certain Relationships
and Related Transactions". The following table shows the base and incremental
volumes of crude oil contracted for delivery and the volumes of crude oil
actually delivered under these contracts in the three years ended December 31,
1998.

The crude supply contracts include force majeure clauses that have been
exercised on certain occasions. Exercise of these clauses requires that the
Company locate alternative sources of supply for its crude oil requirements, and
such action may result in lower operating margins.

(1) The supply agreement for the Lake Charles refinery gives PDVSA the right to
sell to CITGO incremental volumes up to the maximum amount specified in the
table, subject to certain restrictions relating to the type of crude oil to
be supplied, refining capacity and other operational considerations at the
refinery.

(2) Volumes purchased under the supply agreements do not equal purchases from
PDVSA shown in the previous table as a result of spot purchases or transfers
between refineries.

(3) CITGO acquired a participation interest in LYONDELL-CITGO, the owner of the
Houston refinery, on July 1, 1993. In connection with such transaction,
LYONDELL-CITGO entered into a long-term crude oil supply agreement with
PDVSA that provided for delivery volumes of 135 MBPD until the completion of
a refinery enhancement project at which time the delivery volumes increased
to a range that extends from 200 MBPD to 230 MBPD.

Most of the crude oil and feedstocks purchased by CITGO from PDVSA are
delivered on tankers owned by PDV Marina, S.A. ("PDV Marina"), a wholly-owned
subsidiary of PDVSA, or by other PDVSA subsidiaries. In 1998, 82% of the PDVSA
contract crude oil delivered to the Lake Charles and Corpus Christi refineries
was delivered on tankers operated by PDVSA subsidiaries.

CITGO purchases additional crude oil under a 90-day evergreen agreement
with an affiliate of Petroleos Mexicanos ("PEMEX"). CITGO's refineries are
particularly well suited to refine PEMEX's Maya heavy, sour crude oil, which is
similar in many respects to several types of Venezuelan crude oil.

CITGO was a party to a contract with an affiliate of Occidental Petroleum
Corporation ("Occidental") for the purchase of light, sweet crude oil to produce
lubricants. This contract expired on August 31, 1998. CITGO also purchases sweet
crude oil under long-standing relationships with numerous other producers.

10
11

Refined Product Purchases. CITGO is required to purchase refined products
to supplement the production of the Lake Charles and Corpus Christi refineries
in order to meet demand of CITGO's marketing network. During 1998, CITGO's
shortage in gasoline production approximated 329 MBPD. However, due to
logistical needs, timing differences and product grade imbalances, CITGO
purchased approximately 581 MBPD of gasoline and sold into the spot market, or
to refined product traders or other refiners approximately 254 MBPD of gasoline.
The following table shows CITGO's purchases of refined products for the three
years in the period ended December 31, 1998.

As of December 31, 1998, CITGO purchased substantially all of the refined
products, excluding petrochemicals, produced at the LYONDELL-CITGO refinery
under a long-term contract through the year 2017. LYONDELL-CITGO was a major
supplier in 1998 providing CITGO with 120 MBPD of gasoline, 79 MBPD of diesel/#2
fuel and 17 MBPD of jet fuel. See "-- Refining -- LYONDELL-CITGO".

As of May 1, 1997, CITGO began purchasing, under a contract with a
sixty-month term, substantially all of the refined products produced at the
PDVMR refinery. During the period ended December 31, 1998, the PDVMR refinery
provided CITGO with 78 MBPD of gasoline, 42 MBPD of diesel/#2 fuel and 5 MBPD of
jet fuel.

An affiliate of PDVSA acquired a 50 percent equity interest in a refinery
in Chalmette, Louisiana ("Chalmette") in October 1997 and has assigned to CITGO
its option to purchase up to 50 percent of the refined products produced at the
refinery through December 31, 1999. CITGO exercised this option on November 1,
1997, and acquired approximately 65 MBPD of refined products from the refinery
during 1998, approximately one-half of which was gasoline.

In October 1998 an affiliate of PDVSA acquired a 50 percent equity interest
in HOVENSA and has the right under a product sales agreement to assign
periodically to CITGO, or other related parties, its option to purchase 50% of
the refined products produced by HOVENSA (less a certain portion of such
products that HOVENSA will market directly in the local and Caribbean markets).
In addition, under the product sales agreement, the PDVSA affiliate has
appointed CITGO as its agent in designating which of its affiliates shall from
time to time take deliveries of the refined products available to it. The
product sales agreement will be in effect for the life of the joint venture,
subject to termination events based on default or mutual agreement. Pursuant to
the above arrangement, CITGO began acquiring approximately 120 MBPD of refined
products from HOVENSA on November 1, 1998, approximately one-half of which was
gasoline.

Light Fuels. Gasoline sales accounted for 58% of CITGO's refined product
sales in the years 1998, 1997 and 1996. CITGO markets CITGO branded gasoline
through over 15,000 independently owned and operated CITGO branded retail
outlets (including 13,165 branded retail outlets owned and operated by
approximately 824 independent marketers and 1,888 7-Eleven(TM) convenience
stores) located throughout the United States, primarily east of the Rocky
Mountains. CITGO purchases gasoline to supply its marketing network, as the
gasoline production from the Lake Charles and Corpus Christi refineries was only
equivalent to approximately 48%, 47% and 49% of the volume of CITGO branded
gasoline sold in 1998, 1997 and 1996, respectively. See "-- Crude Oil and
Refined Product Purchases -- Refined Product Purchases".

CITGO's strategy is to enhance the value of the CITGO brand in order to
obtain premium pricing for its products by appealing to consumer preference for
quality petroleum products and services. This is accomplished through a
commitment to quality, dependability and customer service to its independent
marketers, which constitute CITGO's primary distribution channel.

Sales to independent branded marketers typically are made under contracts
that range from three to seven years. Sales to 7-Eleven(TM) convenience stores
are made under a contract that extends through the year 2006. Under this
contract, CITGO arranges all transportation and delivery of motor fuels and
handles all product ordering. CITGO also acts as processing agent for the
purpose of facilitating and implementing orders and purchases from third-party
suppliers. CITGO receives a processing fee for such services.

CITGO markets jet fuel directly to airline customers at 26 airports,
including such major hub cities as Atlanta, Chicago, Dallas/Fort Worth, New York
and Miami.

Growth in wholesale rack sales to marketers has been the primary focus of
diesel/#2 marketing efforts. Such marketing efforts have resulted in increases
in wholesale rack sales volume from approximately 1,561 million gallons in 1996
to approximately 1,928 million gallons in 1998. The remaining diesel/#2 fuel
production is sold either in bulk through contract sales (primarily as heating
oil in the Northeast) or on a spot basis.

CITGO's delivery of light fuels to its customers is accomplished in part
through 49 refined product terminals located throughout CITGO's primary market
territory. Of these terminals, 34 are wholly-owned by CITGO and 15 are jointly
owned. Fifteen of CITGO's product terminals have waterborne docking facilities,
which greatly enhance the flexibility of CITGO's logistical system. In addition,
CITGO operates eight terminals owned by PDVMR in the Midwest. Refined product
terminals owned or operated by CITGO provide a total storage capacity of
approximately 23 million barrels. Also, CITGO has active exchange

12
13

relationships with over 270 other refined product terminals, providing
flexibility and timely response to distribution needs.

Petrochemicals and Industrial Products. CITGO sells petrochemicals in bulk
to a variety of U.S. manufacturers as raw materials for finished goods. The
majority of CITGO's cumene production is sold to Mount Vernon Phenol Plant
Partnership ("MVPPP"), a joint venture phenol production plant in which CITGO is
a limited partner. The phenol plant produces phenol and acetone for sale
primarily to the principal partner in the phenol plant for the production of
plastics. Sulphur is sold to the U.S. and international fertilizer industry;
cycle oils are sold for feedstock processing and blending; natural gas liquids
are sold to the U.S. fuel and petrochemical industry; petroleum coke is sold
primarily in international markets, through a joint venture, for use as kiln and
boiler fuel; and residual fuel blendstocks are sold to a variety of fuel oil
blenders and customers.

Asphalt. CITGO markets asphalt through 15 terminals located along the East
Coast, from Savannah, Georgia to Albany, New York. Asphalt is sold primarily to
independent contractors for use in the construction and resurfacing of roadways.
Demand for asphalt in the Northeastern U.S. peaks in the summer months.

Lubricants and Waxes. CITGO markets many different types, grades and
container sizes of lubricants and wax products, with the bulk of sales
consisting of automotive oil and lubricants and industrial lubricants. Other
major lubricant products include 2-cycle engine oil and automatic transmission
fluid.

PIPELINE OPERATIONS

CITGO owns and operates 339 miles of crude oil pipeline systems and
approximately 1,080 miles of products pipeline systems. CITGO also has equity
interests in three crude oil pipeline companies with a total of nearly 5,400
miles of pipeline plus equity interest in six refined product pipeline companies
with a total of approximately 8,000 miles of pipeline. CITGO's pipeline
interests provide it with access to substantial refinery feedstocks and reliable
transportation to refined product markets, as well as cash flows from dividends.
One of the refined product pipelines in which CITGO has an interest, Colonial
Pipeline, is the largest refined product pipeline in the United States
transporting gasoline, jet fuel and diesel/#2 fuel oil from the Gulf Coast to
the mid-Atlantic and eastern seaboard states.

EMPLOYEES

CITGO and its subsidiaries have a total of approximately 4,500 employees,
approximately 1,900 of whom are covered by 15 union contracts. Approximately
1,600 of the union employees are employed in refining operations. The remaining
union employees are located primarily at a lubricant blending and packaging
plant and at various refined product terminals.

Effective February 28, 1998, the stock of Petro-Chemical Transport, Inc.
("PCT"), a wholly owned subsidiary of CITGO, was sold. As a result of this sale,
approximately 420 employees were terminated. The operations of PCT were not
material to CITGO.

ENVIRONMENT AND SAFETY

Environment

Beginning in 1994, the U.S. refining industry was required to comply with
stringent product specifications under the 1990 Clean Air Act ("CAA") Amendments
for reformulated gasoline and low sulphur diesel fuel which necessitated
additional capital and operating expenditures, and altered significantly the
U.S. refining industry and the return realized on refinery investments. In
addition, numerous other factors affect the Company's plans with respect to
environmental compliance and related expenditures. See "Factors Affecting
Forward Looking Statements".

In addition, the Company is subject to various federal, state and local
environmental laws and regulations which may require the Company to take action
to correct or improve the effects on the environment of prior disposal or
release of petroleum substances by the Company or other parties. Management
believes the

13
14

Company is in compliance with these laws and regulations in all material
aspects. Maintaining compliance with environmental laws and regulations in the
future could require significant capital expenditures and additional operating
costs.

Under a 1992 agreement with the Company, a former owner of certain of the
Company's operations and assets, including the Lake Charles refinery,
indemnifies the Company for certain environmental remediation costs, "Superfund"
liabilities and tort liabilities related to those operations and assets
according to relative ownership periods and the terms of the agreement.

A February 1999 order of a Louisiana agency specifies requirements to
complete closure of certain surface impoundments at the Lake Charles refinery.
CITGO and the former owner are participating in this closure and sharing the
related costs based on estimated contributions of waste and ownership periods.
Final closure is expected to begin in 2000.

Based on publicly available information, CITGO believes that the former
owner has the financial capability to fulfill all of its responsibilities under
the 1992 agreement. Accordingly, CITGO believes that its liability exposure
under the Federal Superfund and similar state laws with respect to those sites
for which the former owner provides indemnity is not material.

In July 1997, the Texas Natural Resources Conservation Commission ("TNRCC")
issued a Preliminary Report and Petition alleging that CITGO Refining and
Chemicals Company LP ("CITGO Refining") violated TNRCC rules relating to
operation of a hazardous waste management unit without a permit and recommended
a penalty of $699,200. CITGO Refining disagrees with those allegations and the
proposed penalties. As part of the continuing negotiations, TNRCC has proposed
to settle the alleged violation of hazardous waste management rules and
regulations in addition to alleged unauthorized emissions to the atmosphere and
alleged unauthorized discharge to the waters of the state in return for payment
of a penalty of $786,300.

CITGO's accounting policy establishes environmental reserves as probable
site restoration and remediation obligations become reasonably capable of
estimation. Based on currently available information, including the continuing
participation of former owners in remediation actions and indemnification
agreements with third parties, CITGO believes that its accruals are sufficient
to address its environmental clean-up obligations.

Conditions which require additional expenditures may exist with respect to
various Company sites including, but not limited to, CITGO's operating refinery
complexes, closed refineries, service stations and crude oil and petroleum
storage terminals. The amount of such future expenditures, if any, is
indeterminable.

Increasingly stringent regulatory provisions periodically require
additional capital expenditures. During 1998, CITGO expended approximately $65
million for environmental and regulatory capital improvements in its operations.
Management currently estimates that CITGO will spend approximately $303 million
for environmental and regulatory capital projects over the five-year period
1999-2003. These estimates may vary due to a variety of factors. See "Item
7 -- Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources". See also "Factors Affecting
Forward Looking Statements".

Safety

Due to the nature of petroleum refining and distribution, CITGO is subject
to stringent occupational health and safety laws and regulations. CITGO
maintains comprehensive safety, training and maintenance programs. CITGO
believes that it is in substantial compliance with occupational health and
safety laws.

ITEM 3. LEGAL PROCEEDINGS

Various lawsuits and claims arising in the ordinary course of business are
pending against the Company. The Company records accruals for potential losses
when, in management's opinion, such losses are probable and reasonably
estimable. If known lawsuits and claims were to be determined in a manner
adverse to the

14
15

Company, and in amounts greater than the Company's accruals, then such
determinations could have a material adverse effect on the Company's results of
operations in a given reporting period. However, in management's opinion the
ultimate resolution of these lawsuits and claims will not exceed by a material
amount, the amount of the accruals and the insurance coverage available to the
Company. This opinion is based upon management's and counsel's current
assessment of these lawsuits and claims. The most significant lawsuits and
claims are discussed below.

In a pending case in federal court, Oil Chemical and Atomic Workers, Local
7-517 ("the Union") has asserted claims against CITGO, PDVSA, PDV America,
PDVMR, UNO-VEN and Unocal pursuant to the Labor Management Relations Act. The
Union alleges that CITGO and the other defendants are bound by the terms of a
collective bargaining agreement between UNO-VEN and the Union covering certain
employees at a refinery in Lemont, Illinois. This refinery was acquired by PDVMR
on May 1, 1997 in a transaction involving the former partners of UNO-VEN.
Pursuant to an operating agreement with PDVMR, CITGO became the operator of this
refinery and employed the substantial majority of the employees previously
employed by UNO-VEN pursuant to its initial terms and conditions of employment,
but CITGO did not assume the existing labor agreement. The Union seeks monetary
compensation for certain differences in employee benefits and reinstatement of
all of the UNO-VEN benefit plans. The union also seeks to require CITGO to abide
by the terms of the collective bargaining agreement between the Union and
UNO-VEN. In June 1998, the trial court granted the motions for summary judgment
filed by CITGO and the other defendants; the Union has appealed this ruling.

In May 1997, an explosion and fire occurred at CITGO's Corpus Christi
refinery. No serious personal injuries were reported. The Company received
approximately 7,500 individual claims for personal injury and property damage
related to the above noted incident. Approximately 1,300 of these claims have
been resolved for amounts which individually and collectively are not material.
There are presently six lawsuits pending against the Company in federal and
state courts alleging property damages, personal injury and punitive damages. A
trial in one of the federal court lawsuits in October 1998 involving ten
bellwether plaintiffs, out of approximately 400 plaintiffs, resulted in a
verdict for the Company. The remaining cases are not currently scheduled for
trial. The Company anticipates that the claims of the remaining plaintiffs in
this lawsuit will be resolved for an immaterial amount.

A class action lawsuit is pending in Corpus Christi, Texas state court
against the Company and other operators and owners of nearby industrial
facilities which claims damages for reduced value of residential properties
located in the vicinity of the industrial facilities as a result of air, soil
and groundwater contamination. In 1997, the Company offered to purchase about
275 properties in a neighborhood adjacent to the Company's Corpus Christi
refinery, which were included in the lawsuit. Related to this offer, $15.7
million was expensed in 1997. To date, the Company has reached agreements to buy
all but 18 of such properties, which include settlements of property damage
claims, and has offers open to purchase the remaining properties. Two related
personal injury and wrongful death lawsuits were filed against the same
defendants in 1996 and are scheduled for trial in 1999.

Litigation is pending in federal court in Lake Charles, Louisiana, against
CITGO by a number of current and former Lake Charles refinery employees and
applicants asserting claims of racial discrimination in connection with the
Company's employment practices. Trials in this case are set to begin in the fall
of 1999.

The Company is among defendants to lawsuits in California and North
Carolina alleging contamination of water supplies by methyl tertiary butyl ether
("MTBE"), a component of gasoline. The action in California was filed in
November 1998 by the South Tahoe Public Utility District and the Company was
added as a defendant in February 1999. The North Carolina case, filed in January
1999, is a putative class action on behalf of owners of water wells and other
drinking water supplies in the state. Both actions allege that MTBE poses public
health risks. Both actions seek damages as well as remediation of the alleged
contamination. These matters are in early stages and no discovery has been
conducted against the Company. The Company intends to deny all of the
allegations and is pursuing its defenses.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

The following discussion of the financial condition and results of
operations of CITGO should be read in conjunction with the consolidated
financial statements of CITGO included elsewhere herein.

Petroleum industry operations and profitability are influenced by a large
number of factors, some of which individual petroleum refining and marketing
companies cannot entirely control. Governmental regulations and policies,
particularly in the areas of taxation, energy and the environment, have a
significant impact on petroleum activities, regulating how companies conduct
their operations and formulate their products, and, in some cases, limiting
their profits directly. Demand for crude oil and refined products is largely
driven by the condition of local and worldwide economies, although weather
patterns and taxation relative to other energy sources also play a significant
part. CITGO's consolidated operating results are affected by these industry-
specific factors and by company-specific factors, such as the success of
marketing programs and refinery operations.

The earnings and cash flows of companies engaged in the refining and
marketing business in the United States are primarily dependent upon producing
and selling quantities of refined products at margins sufficient to cover fixed
and variable costs. The refining and marketing business is characterized by high
fixed costs resulting from the significant capital outlays associated with
refineries, terminals and related facilities. This business is also
characterized by substantial fluctuations in variable costs, particularly costs
of crude oil, feedstocks and blending components, and in the prices realized for
refined products. Crude oil and refined products are commodities whose price
levels are determined by market forces beyond the control of CITGO.

In general, prices for refined products are significantly influenced by the
price of crude oil, feedstocks and blending components. Although an increase or
decrease in the price for crude oil, feedstocks and blending components
generally results in a corresponding increase or decrease in prices for refined
products, generally there is a lag in the realization of the corresponding
increase or decrease in prices for refined products. The effect of changes in
crude oil prices on CITGO's consolidated operating results therefore depends in
part on how quickly refined product prices adjust to reflect these changes. A
substantial or prolonged increase in crude oil prices without a corresponding
increase in refined product prices, a substantial or prolonged decrease in
refined product prices without a corresponding decrease in crude oil prices, or
a substantial or prolonged decrease in demand for refined products could have a
significant negative effect on the Company's earnings and cash flows. CITGO
purchases a significant amount of its crude oil requirements from PDVSA under
long-term supply agreements (expiring in the years 2006 through 2013). These
supply agreements were designed to reduce the volatility of earnings and cash
flows from CITGO's refining operations by providing a relatively stable level of
gross margin on crude oil supplied by PDVSA. This supply represented
approximately 58% percent of the crude oil processed in refineries operated by
CITGO in the year ended December 31, 1998. The crude supply contracts include
force majeure clauses that have been exercised on certain occasions. Exercise of
these clauses requires that the Company locate alternative sources of supply for
its crude oil requirements, and such action may result in lower operating
margins. CITGO also purchases significant volumes of refined products to
supplement the production from its refineries to meet marketing demands and to
resolve logistical issues. CITGO's earnings and cash flows are also affected by
the cyclical nature of petrochemical prices. As a result of these factors, the
earnings and cash flows of CITGO may experience substantial fluctuations.

17
18

Inflation was not a significant factor in the operations of CITGO during the
three years ended December 31, 1998.

In July 1997 the Company's senior management implemented a Transformation
Program designed to ensure that numerous expense controls, business information
systems and business efficiency initiatives underway were effectively
coordinated to achieve desired results. Included in this program were reviews of
the Company's business units, assets, strategies, and business processes. These
combined actions include personnel reductions (the "Separation Programs"). The
cost of the Separation Programs was approximately $8 million and $22 million for
the years ended December 31, 1998 and 1997, respectively. In addition, as part
of the Transformation Program, the first phase of Systems, Applications and
Products in Data Processing ("SAP") implementation, which included the financial
reporting and materials management systems, was brought into production on
January 1, 1998. Additional SAP modules, including plant maintenance work order
and cost tracking, were implemented throughout 1998. The implementation will
continue in 1999.

The following table summarizes the sources of CITGO's sales revenues and
volumes.

RESULTS OF OPERATIONS -- 1998 COMPARED TO 1997

Sales revenues and volumes. Sales decreased by $2,679 million, representing
a 20% decrease from 1997 to 1998. This was due to a decrease in average sales
price of 28% partially offset by an increase in sales volumes of 11%. (See CITGO
Sales Revenue and Volumes table above.)

Equity in earnings (losses) of affiliates. Equity in earnings of affiliates
increased by approximately $13 million, or 20% from $64 million in 1997 to $77
million in 1998. This increase was due primarily to a

18
19

$14 million increase in CITGO's equity in earnings of LYONDELL-CITGO as a result
of the change in CITGO's interest in LYONDELL-CITGO which increased from
approximately 13% at December 31, 1996 to approximately 42% on April 1, 1997 and
the improvement in LYONDELL-CITGO's operations since completion of its refinery
enhancement project during the first quarter of 1997 (See Consolidated Financial
Statements of CITGO -- Note 3 in Item 14a).

Cost of sales and operating expenses. Cost of sales and operating expenses
decreased by $2,680 million, or 21% from 1997 to 1998. (See CITGO Cost of Sales
and Operating Expenses table above.)

CITGO purchases refined products to supplement the production from its
refineries to meet marketing demands and resolve logistical issues. The refined
product purchases represented 59% of cost of sales for the years 1998 and 1997.
These refined product purchases included purchases from LYONDELL-CITGO, PDVMR,
Chalmette and HOVENSA. CITGO estimates that margins on purchased products, on
average, are lower than margins on produced products due to the fact that CITGO
can only receive the marketing portion of the total margin received on the
produced refined products. However, purchased products are not segregated from
CITGO produced products and margins may vary due to market conditions and other
factors beyond the Company's control. As such, it is difficult to measure the
effects on profitability of changes in volumes of purchased products. CITGO
anticipates its purchased product requirements will continue to increase, in
volume and as a percentage of refined products sold, in order to meet marketing
demands, although in the near term, other than normal refinery turnaround
maintenance, CITGO does not anticipate operational actions or market conditions
which might cause a material change in anticipated purchased product
requirements; however, there could be events beyond the control of CITGO which
impact the volume of refined products purchased. See also "Factors Affecting
Forward Looking Statements".

Gross margin. The gross margin in 1998 was $572 million, which is
essentially unchanged from 1997. This occurred because a sales volume increase
of approximately 11% was sufficient to offset the 9% erosion of gross margin on
a per gallon basis which includes a lower of cost or market adjustment of $159
million.

Selling, general and administrative expenses. Selling, general and
administrative expenses increased $42 million, or 21% in 1998. The increase is
due primarily to salary and related burden allocations as well as increases in
advertising expense and depreciation.

Interest expense. Interest expense decreased $25.6 million from 1997 to
1998. The decrease was primarily due to the decrease in average debt outstanding
related to a decrease in working capital requirements and the deferral of a
significant 1998 excise tax payment. Also the average interest rate decreased
due to a decrease in key rates and replacement of higher rate debt with lower
rate debt.

Income taxes. CITGO's provision for income taxes in 1998 was $103 million,
representing an effective tax rate of 35%. In 1997, CITGO's provision for income
taxes was $91 million, representing an effective tax rate of 31%. The relatively
low rate in 1997 was due primarily to the favorable resolution of a significant
tax issue with the Internal Revenue Service in the second quarter of 1997. The
resolution resulted in the reduction of a contingency reserve previously
established related to this matter. The decrease was partially offset by the
recording of a valuation allowance related to a capital loss carryforward. In
1998 the effective tax rate decreased slightly compared to the 1996 rate due to
a decrease in state taxes.

RESULTS OF OPERATIONS -- 1997 COMPARED TO 1996

Sales revenues and volumes. Sales increased by $639 million, representing a
5% increase from 1996 to 1997. The increase was due to an increase in sales
volumes of 8% partially offset by a decrease in average sales prices of 3%. (See
CITGO Sales Revenue and Volumes table above.)

Equity in earnings (losses) of affiliates. Equity in earnings of affiliates
increased by approximately $43 million, or 205% from $21 million in 1996 to $64
million in 1997. This increase was due primarily to a $43 million increase in
CITGO's equity earnings of LYONDELL-CITGO. This increase was due primarily to
the change in CITGO's interest in LYONDELL-CITGO which increased from
approximately 13% at December 31, 1996 to approximately 42% on April 1, 1997 and
the improvement in LYONDELL-CITGO's

19
20

operations since completion of its refinery enhancement project during the first
quarter of 1997 (See Consolidated Financial Statements of CITGO -- Note 3 in
Item 14a).

Other income (expense). Other income (expense) was $(10.5) million for the
year ended December 31, 1997 as compared to $(4.2) million for the same period
in 1996. The 1997 amount includes $8.7 million in loss reserves on a lubricants
plant and retail properties, a $5.8 million write off of a capital project, $5.8
million in fees related to the sale of trade accounts, notes and credit card
receivables in June and November 1997 and a $2.6 million write off of
miscellaneous assets. These items were offset by a net $8.3 million property
insurance recovery relating to the Corpus Christi alkylation unit fire during
the third quarter, a $3.1 million net management fee charged to PDVMR over the
year and a $1.3 million gain on the sale of pipeline assets in the first quarter
of 1997.

Cost of sales and operating expenses. Cost of sales and operating expenses
increased by $529 million, or 4% from 1996 to 1997. (See CITGO Cost of Sales and
Operating Expenses table above.)

CITGO purchases refined products to supplement the production from its
refineries to meet marketing demands and resolve logistical issues. The refined
product purchases represented 59% and 57% of cost of sales for the years 1997
and 1996, respectively. These refined product purchases included purchases from
LYONDELL-CITGO, PDVMR and Chalmette.

Gross margin. The gross margin for 1997 was $571 million, or 4.2%, compared
to $461 million, or 3.6% for 1996. Gross margins in 1997 were positively
affected by high crude runs during periods of strong refining margins as well as
asphalt and petrochemical activities.

Selling, general and administrative expenses. Selling, general and
administrative expenses increased $35 million, or 21%, due primarily to
increased selling expenses in 1997 including the effect of the change in focus
of the Company's marketing programs initiated in April 1996 and increases in
several other areas including purchasing, administrative services, information
systems, corporate executive, credit card and other charges, none of which
increased more than $6 million individually, but in the aggregate increased
approximately $30 million for the year.

Interest expense. Interest expense increased $11.5 million from 1996 to
1997. The increase was primarily due to the public debt and certain industrial
revenue bonds which were outstanding for the entire year in 1997 compared to
only a partial year during 1996 and CITGO's revolving bank loan which had a
higher outstanding balance during most of 1997 as compared to 1996.

Income taxes. CITGO's provision for income taxes in 1997 was $91 million,
representing an effective tax rate of 31%. In 1996, CITGO's provision for income
taxes was $70 million, representing an effective tax rate of 36%. The decrease
is due primarily to the favorable resolution of a significant tax issue with the
Internal Revenue Service in the second quarter of 1997. The resolution resulted
in the reduction of a contingency reserve previously established related to this
matter. The decrease was partially offset by the recording of a valuation
allowance related to a capital loss carryforward.

LIQUIDITY AND CAPITAL RESOURCES

For the year ended December 31, 1998, CITGO's net cash provided by
operating activities totaled approximately $583 million, primarily reflecting
$194 million of net income, $222 million of depreciation and amortization, a
lower of cost or market adjustment to inventory of $159 million and the net
effect of other items of $8 million. The more significant changes in other items
included the decrease in accounts receivable, including receivables from
affiliates, of approximately $94 million, the decrease in accounts payable and
other current liabilities, including payables to affiliates, of approximately
$126 million and the increase of other assets of approximately $52 million.

Net cash used in investing activities in 1998 totaled $215 million
consisting primarily of capital expenditures of $200 million and a loan to
LYONDELL-CITGO of $19.8 million.

20
21

During the same period, consolidated net cash used in financing activities
totaled approximately $363 million comprised primarily of $486 million of
dividends offset by net additional borrowings of $73 million and a $50 million
capital contribution from PDV America.

CITGO currently estimates that its capital expenditures for the years 1999
through 2003 will total approximately $1.5 billion. These include:

CITGO ESTIMATED CAPITAL EXPENDITURES -- 1999 THROUGH 2003(1)

Affecting Forward Looking Statements".

As of December 31, 1998, the Company and its subsidiaries had an aggregate
of $1,343 million of indebtedness outstanding that matures on various dates
through the year 2028. As of December 31, 1998, the Company's contractual
commitments to make principal payments on this indebtedness were $84.1 million,
$47.1 million and $47.1 million for 1999, 2000 and 2001, respectively. The
Company's bank credit facility consists of a $400 million, five year, revolving
bank loan and a $150 million, 364 day, revolving bank loan, both of which are
unsecured and have various borrowing maturities, of which $165 million was
outstanding at December 31, 1998. Cit-Con has a separate credit agreement under
which $21.4 million was outstanding at December 31, 1998. The Company's other
principal indebtedness consists of (i) $199.7 million in senior notes issued in
1996, (ii) $260 million in senior notes issued pursuant to a master shelf
agreement with an insurance company, (iii) $177 million in senior notes issued
in 1991, (iv) $276 million in obligations related to tax exempt bonds issued by
various governmental units, and (v) $208 million in obligations related to
taxable bonds issued by a governmental unit. (See Consolidated Financial
Statements of CITGO -- Note 9 and 10 in Item 14a.)

As of December 31, 1998, capital resources available to CITGO included cash
provided by operations, available borrowing capacity of $385 million under
CITGO's revolving credit facility and $138 million in unused availability under
uncommitted short-term borrowing facilities with various banks. Additionally,
the remaining $400 million from CITGO's shelf registration with the Securities
and Exchange Commission for $600 million of debt securities may be offered and
sold from time to time. CITGO believes that it has sufficient capital resources
to carry out planned capital spending programs, including regulatory and
environmental projects in the near term, and to meet currently anticipated
future obligations as they arise. CITGO periodically evaluates other sources of
capital in the marketplace and anticipates long-term capital requirements will
be satisfied with current capital resources and future financing arrangements,
including the issuance of debt securities. The Company's ability to obtain such
financing will depend on numerous factors, including market conditions and the
perceived creditworthiness of the Company at that time. See "Factors Affecting
Forward Looking Statements".

CITGO's debt instruments impose restrictions on CITGO's ability to incur
additional debt, place liens on property, sell or acquire fixed assets, and make
restricted payments, including dividends.

CITGO is a member of the PDV America consolidated Federal income tax return.
CITGO has a tax allocation agreement with PDV America, which is designed to
provide PDV America with sufficient cash to pay its consolidated income tax
liabilities. (See Consolidated Financial Statements of CITGO -- Note 1 and Note
4 in Item 14a).

NEW ACCOUNTING STANDARDS

Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income." The Company had
no items of other comprehensive income during the three years ended December 31,
1998.

In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures About Segments of an Enterprise and Related Information"
("SFAS No. 131"), which is effective for the fiscal year ending December 31,
1998. SFAS No. 131 modifies current segment reporting requirements and
establishes, for public companies, criteria for reporting disclosures about a
company's products and services, geographic areas and major customers in annual
and interim financial statements. The Company has determined that its operations
comprise a single reportable segment.

In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits" ("SFAS No. 132") which is effective for the Company's
fiscal year ending December 31, 1998. The statement revises current employers'
disclosure requirements for pensions and other postretirement benefits. It does
not change the measurement or recognition of costs or liabilities associated
with those plans.

In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
No. 133"). The statement establishes accounting and reporting standards for
derivative instruments and for hedging activities. It requires that an entity
recognize all derivatives, at fair value, as either assets or liabilities in the
statement of financial position with an offset either to shareholder's equity
and comprehensive income or income depending upon the classification of the
derivative. The Company has not determined the impact on its financial
statements that may result from adoption of SFAS No. 133, which is required no
later than January 1, 2000.

YEAR 2000 READINESS

General. The inability of computers, software and other equipment using
microprocessors to recognize and properly process data fields containing a
two-digit year is commonly referred to as the Year 2000 issue. As the Year 2000
approaches, such systems may be unable to accurately process certain date-based
information.

To mitigate any adverse impact this may cause, CITGO has established a
company wide Year 2000 Project ("Project") to address the issue of computer
programs and embedded computer chips which may be unable to correctly function
with the Year 2000. The Project is proceeding on schedule. In addition, CITGO is
updating major elements of its information systems by implementing programs
purchased from SAP. The first phase of SAP implementation, which included the
financial reporting and materials management systems, was brought into
production on January 1, 1998. Additional SAP modules including plant
maintenance work order and cost tracking were implemented throughout 1998. The
implementation will continue in 1999. The total cost of the SAP implementation
is estimated to be approximately $110 million, which includes software,
hardware, reengineering and change management. Management has determined that
SAP is an appropriate solution to the Year 2000 issue related to the systems for
which SAP is implemented. Such systems comprise approximately 80 percent of
CITGO's total information systems. The implementation of SAP is 70 to 75 percent
complete, and is on schedule and on budget as of December 31, 1998. Remaining
business software systems are expected to be made Year 2000 ready through the
Year 2000 Project or they will be replaced.

The Project. CITGO's Year 2000 Project Team is divided into two groups. One
group is working with Information Systems ("I.S.") and Information Technology
("I.T.") related matters, while the other is analyzing non-I.S./I.T. business
and asset integrity matters. A risk-based approach toward Year 2000 readiness
was applied to non-SAP systems and processes, with most fix-or-replace decisions
made by year-end 1998. The strategy for achieving Year 2000 business and asset
integrity is focused on equipment, software and relationships that are critical
to the Company's primary business operations, including refinery operations,
terminal operations, crude oil purchase and shipment operations, and refined
product distribution operations. The Company engaged third party consultants to
review and validate the methodology and organization of the

22
23

Project. The Project strategy involves a number of phases: Inventory and
Assessment of Critical Equipment, Software and Relationships; Contingency
Planning; Remediation; Testing; and Readiness.

The Inventory and Assessment of Critical Equipment and Software phase of
the Project has been completed. The Inventory and Assessment of business
relationships with customers and suppliers to assure continuity of purchases,
sales and inter-company communications began in June 1998. CITGO now requires
that all new contracts with vendors, suppliers, or business partners include a
clause covering Year 2000 readiness. CITGO also seeks evidence of Year 2000
readiness from service providers prior to procuring new services.

While the CITGO Project is systematically assessing the Year 2000 readiness
of third party suppliers and customers, there can be no guarantee that third
parties of business importance to the Company will successfully and timely
reprogram, replace, or test all of their own computer hardware, software and
process control systems. CITGO has therefore chosen to continue assessment and
reevaluation of third party relationships beyond the deadline for completion of
other aspects of Inventory and Assessment phases of the Project. Reviews of
third party Year 2000 readiness will continue through 1999.

CITGO has also established a Year 2000 Contingency Planning Team. The
strategy for Contingency Planning includes a review and analysis of existing
contingency plans for CITGO refineries, terminals, pipelines and other
operations, in light of potential Year 2000 issues discovered in the Inventory
and Assessment phases of the Project. The Contingency Planning phase will also
evaluate and implement changes to the existing contingency plans. Contingency
plans based on this process are scheduled to be enacted in phases, with
completion scheduled for June 30, 1999. Additional planning is underway for the
Remediation phase of the Project. Remediation has begun and includes technical
analysis, testing and, if necessary, retrofitting or replacement of systems and
equipment determined to be incapable of reliable operations in the Year 2000.
Target for completion of the Remediation phase is August 1, 1999. The final
phase of the Project, Readiness, is being conducted concurrently with other
Project phases. As systems, equipment, processes and business relationships are
determined and documented as Year 2000 ready, Project resources are being
shifted to pursue Readiness in remaining areas of the enterprise.

The following is CITGO's definition of Year 2000 Readiness:

- Correctly and accurately handle date information before, during and after
midnight, December 31, 1999.

- Function correctly and accurately, and without disruption, before, during
and after January 1, 2000.

- Respond to two-digit year date input in a way that resolves ambiguity as
to the century in a disclosed, defined and predetermined manner.

- Process all date data to reflect the year 2000 as a leap year.

- Correctly and accurately recognize and process any date with a year
specified as "99" and "00".

Costs. The estimated total cost of the Project is not more than $25
million, down from an original estimate of $35 million. The reduction is due to
less than expected need for remediation of embedded systems and refinements in
expense estimates. This estimate does not include CITGO's potential share of
Year 2000 costs that may be incurred by partnerships and joint ventures in which
CITGO participates but is not the managing partner or operator. The total amount
expended through December 31, 1998 was approximately $5.9 million. Approximately
65% of these expenditures were for internal costs to conduct the company-wide
Inventory and Assessment phases of the Project. The remaining 35% of the cost
was for consultants in the specialized areas of Project Management, Contingency
Planning, Information Technology, Database Administration and Operations
Analysis, as well as fees paid to third parties for Quality Assessment analysis
of Project organization and methodology.

The costs of the Project are being funded with cash from operations. No
existing or planned I.T. projects have been deferred or delayed due to Year 2000
readiness initiatives. The cost of implementing SAP replacement systems is not
included in these estimates.
23
24

The majority of estimated future costs for completing the Project are
anticipated to be directed toward the replacement and repair of systems and
equipment found to be incapable of reliable operation in the Year 2000.
Estimates for replacement and repair costs will be refined over time as the
Remediation phase progresses.

Risks. The failure to correct a material Year 2000 problem could result in
an interruption, or failure of, certain normal business activities or
operations. Because the Company is dependent, to a very substantial degree, upon
the proper functioning of its computer systems and its interaction with third
parties, including vendors and customers and their computer systems, a failure
of any of these systems to be Year 2000 compliant could have a material adverse
effect on the Company. Failure of this kind could, for example, cause disruption
in the supply of crude oil, cause disruption in refinery operations, cause
disruption in the distribution of refined products, lead to incomplete or
inaccurate accounting, recording, or processing of purchases of supplies or
sales of refined products, or result in generation of erroneous results. If not
remedied, potential risks include business interruption, financial loss,
regulatory actions, reputational harm, and legal liability. Such failures could
adversely affect CITGO's results of operations, liquidity and financial
condition. Unlike other business interruption scenarios, Year 2000 implications
could include multiple, simultaneous events which could result in unpredictable
outcomes.

Due to the general uncertainty inherent in the Year 2000 problem, resulting
in part from the uncertainty of the Year 2000 readiness of third party suppliers
and customers, CITGO management is unable to determine at this time whether the
consequences of Year 2000 failures will have a material impact on the Company's
operations, liquidity or financial position. The Project is expected to
significantly reduce the Company's level of uncertainty about the Year 2000
impact. CITGO management believes that, with the implementation of new SAP
business systems and completion of the Project as scheduled, the possibility of
significant interruptions of normal operations should be minimized. See also
"Factors Affecting Forward Looking Statements".

ITEM 7 A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Introduction. CITGO has exposure to price fluctuations of crude oil and
refined products as well as fluctuations in interest rates. To manage these
exposures, management has defined certain benchmarks consistent with its
preferred risk profile for the environment in which the Company operates and
finances its assets. CITGO does not attempt to manage the price risk related to
all of its inventories of crude oil and refined products. As a result, at
December 31, 1998, CITGO was exposed to the risk of broad market price declines
with respect to a substantial portion of its crude oil and refined product
inventories. The following disclosures do not attempt to quantify the price risk
associated with such commodity inventories.

Commodity Instruments. CITGO balances its crude oil and petroleum product
supply/demand and manages a portion of its price risk by entering into petroleum
futures contracts, options and other over-the-counter commodity derivatives.
Generally, CITGO's risk management strategies qualify as hedges. However,
certain strategies do not qualify as hedges. CITGO may take commodity positions
based on its views or expectations of specific commodity prices or price
differentials between commodity types.

Debt Related Instruments. CITGO has fixed and floating U.S. currency
denominated debt. CITGO uses interest rate swaps to manage its debt portfolio
toward a benchmark of 40 to 60 percent fixed rate debt to total fixed and
floating rate debt. These instruments have the effect of changing the interest
rate with the objective of minimizing CITGO's long-term costs. At December 31,
1998, CITGO's primary exposures were to U.S. dollar LIBOR and U.S. Treasury
rates.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

Not applicable.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Certain members of the Board of Directors of CITGO are also directors or
executive officers of PDVSA.

CITGO has entered into several transactions with PDVSA or other affiliates
of PDVSA, including crude oil and feedstock supply agreements, agreements for
the purchase of refined products and transportation agreements. These crude oil
supply agreements require PDVSA to supply minimum quantities of crude oil and
other feedstocks to CITGO for a fixed period, usually 20 to 25 years. The supply
agreements differ somewhat for each entity and each CITGO refinery but generally
incorporate formula prices based on the market value of a slate of refined
products deemed to be produced for each particular grade of crude oil or
feedstock, less (i) certain deemed refining costs; (ii) certain actual costs,
including transportation charges, import duties and taxes; and (iii) a deemed
margin, which varies according to the grade of crude oil or feedstock delivered.
Under each supply agreement, deemed margins and deemed costs are adjusted
periodically by a formula primarily based on the rate of inflation. Because
deemed operating costs and the slate of refined products deemed to be produced
for a given barrel of crude oil or other feedstock do not necessarily reflect
the actual costs and yields in any period, the actual refining margin earned by
a purchaser under the various supply agreements will vary depending on, among
other things the efficiency with which such purchaser conducts its operations
during such period. These supply agreements are designed to reduce the inherent
earnings volatility of the refining operations of CITGO. Prior to 1995, certain
costs were used in the CITGO supply agreement formulas, aggregating
approximately $70 million per year, which were to cease being deductible after
1996. Commencing in the third quarter of 1995, a portion of such deductions were
deferred from 1995 and 1996 to the years 1997 through 1999. In 1998, the effect
of the adjustments to the original modifications was to reduce the price of
crude oil purchased from PDVSA by approximately $25 million. The Company
anticipates that the effect of the adjustments to the original modifications
will be to reduce the price of crude oil purchased from PDVSA under these
agreements by approximately $25 million in 1999, as compared to the original
modification and without giving effect to any other factors that may affect the
price payable for crude oil under these agreements. Due to the pricing formula
under the supply agreements, the aggregate price actually paid for crude oil
purchased from PDVSA under these agreements depends primarily upon the current
prices for refined products and certain actual costs of CITGO. This estimate is
based on the assumption that CITGO will purchase the base volumes of crude oil
under the agreements. See also "Factors Affecting Forward Looking Statements".

LYONDELL-CITGO owns and operates a 265 MBPD refinery in Houston, Texas.
LYONDELL-CITGO was formed in 1993 by subsidiaries of CITGO and Lyondell,
referred to as the owners. CITGO contributed cash during the years 1993 through
1997 for a participation interest and other commitments related to
LYONDELL-CITGO's refinery enhancement project, and Lyondell contributed the
Houston refinery and related assets for the remaining participation interest.
The refinery enhancement project to

26
27

increase the refinery's heavy crude oil high conversion capacity was
substantially completed at the end of 1996 with an in-service date of March 1,
1997. The heavy crude oil processed by the Houston refinery is supplied by PDVSA
under a long-term crude oil supply agreement through the year 2017, and CITGO
purchases substantially all of the refined products produced at the Houston
refinery under a long-term contract (See Consolidated Financial Statements of
CITGO -- Notes 3 and 4 in Item 14a).

Under such long-term supply agreements and refined product purchase
agreements, CITGO and LYONDELL-CITGO purchased approximately $1.4 billion and
$0.5 billion respectively, of crude oil, feedstocks and refined products at
market related prices from PDVSA in 1998. At December 31, 1998, $74 million was
included in CITGO's current payable to affiliates as a result of its
transactions with PDVSA.

CITGO's participation interest in LYONDELL-CITGO was approximately 41% at
December 31, 1998, in accordance with agreements between the owners concerning
such interest. CITGO has a one-time option exercisable after January 1, 2000 but
before September 30, 2000, to increase, for an additional investment, its
participation interest to 50%.

CITGO loaned $19.8 million and $16.5 million to LYONDELL-CITGO during 1998
and 1997, respectively. The notes bear interest at market rates which were
approximately 5.9% at December 31, 1998 and 1997, and are due July 1, 2003.
These notes are included in other assets at December 31, 1998 and 1997.

CITGO accounts for its investment in LYONDELL-CITGO using the equity method
of accounting and records its share of the net earnings of LYONDELL-CITGO based
on allocations of income agreed to by the owners.

On May 1, 1997, PDV America and Union Oil Company of California ("Unocal")
closed a transaction relating to The UNO-VEN Company ("UNO-VEN"). The
transaction transferred certain assets and liabilities to PDVMR, a subsidiary of
PDV America, in liquidation of PDV America's 50% ownership interest in UNO-VEN.
The assets include a refinery in Lemont, Illinois, as well as product
distribution terminals and retail sites located in the Midwest. CITGO operates
these facilities and purchases the products produced at the refinery (See
Consolidated Financial Statements of CITGO -- Note 2 in Item 14a). A portion of
the crude oil processed by PDVMR is supplied by PDVSA under a long-term crude
supply contract.

An affiliate of PDVSA acquired a 50 percent equity interest in Chalmette in
October 1997 and has assigned to CITGO its option to purchase up to 50 percent
of the refined products produced at the refinery through December 31, 1999 (See
Consolidated Financial Statements of CITGO -- Note 2 in Item 14a). CITGO
exercised this option on November 1, 1997, and acquired approximately 65 MBPD of
refined products from the refinery during 1998, approximately one-half of which
was gasoline.

In October 1998 an affiliate of PDVSA acquired a 50 percent equity interest
in HOVENSA and has the right under a product sales agreement to assign
periodically to CITGO, or other related parties, its option to purchase 50% of
the refined products produced by HOVENSA (less a certain portion of such
products that HOVENSA will market directly in the local and Caribbean markets).
In addition, under the product sales agreement, the PDVSA affiliate has
appointed CITGO as its agent in designating which of its affiliates shall from
time to time take deliveries of the refined products available to it. The
product sales agreement will be in effect for the life of the joint venture,
subject to termination events based on default or mutual agreement (See
Consolidated Financial Statements of CITGO -- Note 2 in Item 14a). Pursuant to
the above arrangement, CITGO began acquiring approximately 120 MBPD of refined
products from HOVENSA on November 1, 1998, approximately one-half of which was
gasoline.

The purchase agreements with LYONDELL-CITGO, PDVMR, Chalmette and HOVENSA
incorporate various formula prices based on published market prices and other
factors. Such purchases totaled $2.9 billion for 1998. At December 31, 1998, $64
million was included in payables to affiliates as a result of these
transactions.

CITGO had refined product, feedstock, crude oil and other product sales of
$164 million to affiliates, including LYONDELL-CITGO and MVPPP, in 1998. At
December 31, 1998, $34 million was included in Due from affiliates as a result
of these transactions.

CITGO has guaranteed approximately $99 million of debt of certain
affiliates, including $50 million related to HOVENSA and $11 million related to
Nelson Industrial Steam Company. (See Consolidated Financial Statements of
CITGO -- Note 13 in Item 14a.)

Under a separate guarantee of rent agreement, PDVSA has guaranteed payment
of rent, stipulated loss value and termination value due under the lease of the
Corpus Christi Refinery West Plant facilities. (See Consolidated Financial
Statements of CITGO -- Note 14 in Item 14a.)

The Company and PDV America are parties to a tax allocation agreement that
is designed to provide PDV America with sufficient cash to pay its consolidated
income tax liabilities. In 1996, $12.7 million due from CITGO to PDV America
under this tax allocation agreement for the tax years 1992 through 1994 was
reclassified as a noncash contribution of capital. In December 1996, $0.8
million due from PDV America to CITGO under this tax allocation agreement for
the 1995 tax year was reclassified as a noncash dividend. In 1997, $10 million
due from PDV America under this tax allocation agreement for the 1996 tax year
was classified as a noncash dividend. In 1998, $7.6 million due from CITGO to
PDV America under this agreement for the 1997 tax year was classified as a
noncash contribution of capital. In the event that CITGO should cease to be part
of the consolidated federal income tax return, any amounts included in
shareholder's equity under this agreement are required to be paid to PDV
America. At December 31, 1998, CITGO has income taxes receivable of $12 million
included in prepaid expenses and a $5 million receivable from PDV America
included in due from affiliates.

1998 AND INDEPENDENT AUDITORS' REPORT

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholder of
CITGO Petroleum Corporation:

We have audited the accompanying consolidated balance sheets of CITGO
Petroleum Corporation and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, shareholder's equity and cash flows
for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of CITGO Petroleum Corporation and
subsidiaries at December 31, 1998 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1998 in conformity with generally accepted accounting principles.

CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
EACH OF THE THREE YEARS IN THE PERIOD ENDED DECEMBER 31, 1998

1. SIGNIFICANT ACCOUNTING POLICIES

Description of Business -- CITGO Petroleum Corporation ("CITGO" or the
"Company") is a subsidiary of PDV America, Inc. ("PDV America" or the "Parent"),
an indirect wholly owned subsidiary of Petroleos de Venezuela, S.A. ("PDVSA"),
the national oil company of the Republic of Venezuela.

CITGO manufactures or refines and markets quality transportation fuels as
well as lubricants, refined waxes, petrochemicals, asphalt and other industrial
products. CITGO owns and operates two modern, highly complex crude oil
refineries (Lake Charles, Louisiana, and Corpus Christi, Texas) and two asphalt
refineries (Paulsboro, New Jersey, and Savannah, Georgia) with a combined
aggregate rated crude oil refining capacity of 582 thousand barrels per day
("MBPD"). CITGO also owns a minority interest in LYONDELL-CITGO Refining LP, a
limited partnership (formerly a limited liability company) that owns and
operates a refinery in Houston, Texas, with a rated crude oil refining capacity
of 265 MBPD. CITGO also operates a 153 MBPD refinery in Lemont, Illinois, owned
by PDV Midwest Refining L.L.C. CITGO's consolidated financial statements also
include accounts relating to a 65 percent owned lubricant and wax plant,
pipelines, and equity interests in pipeline companies and petroleum storage
terminals.

CITGO's transportation fuel customers include primarily CITGO branded
wholesale marketers, convenience stores and airlines located mainly east of the
Rocky Mountains. Asphalt is generally marketed to independent paving contractors
on the East Coast of the United States. Lubricants are sold to independent
marketers, mass marketers and industrial customers, and petrochemical feedstocks
and industrial products are sold to various manufacturers and industrial
companies throughout the United States. Petroleum coke is sold primarily in
international markets.

Principles of Consolidation -- The consolidated financial statements
include the accounts of CITGO and its subsidiaries (collectively referred to as
the "Company"). All subsidiaries are wholly owned except for Cit-Con Oil
Corporation ("Cit-Con"), which is 65 percent owned. All material intercompany
transactions and accounts have been eliminated.

The Company's investments in less than majority-owned affiliates are
accounted for by the equity method. The excess of the carrying value of the
investments over the equity in the underlying net assets of the affiliates is
amortized on a straight-line basis over 40 years, which is based upon the
estimated useful lives of the affiliates' assets.

Estimates, Risks and Uncertainties -- The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

CITGO's operations can be influenced by domestic and international
political, legislative, regulatory and legal environments. In addition,
significant changes in the prices or availability of crude oil and refined
products could have a significant impact on CITGO's results of operations for
any particular year.

Impairment of Long-Lived Assets -- The Company periodically evaluates the
carrying value of long-lived assets to be held and used when events and
circumstances warrant such a review. The carrying value of a long-lived asset is
considered impaired when the separately identifiable anticipated undiscounted
cash flow from such asset is less than its carrying value. In that event, a loss
is recognized based on the amount by which the carrying value exceeds the fair
value of the long-lived asset. Fair value is determined primarily using the
anticipated cash flows discounted at a rate commensurate with the risk involved.
Losses on long-lived assets to be disposed of are determined in a similar
manner, except that fair values are reduced for disposal costs.

Revenue Recognition -- Revenue from sales of products is recognized upon
transfer of title, based upon the terms of delivery.

Supply and Marketing Activities -- The Company engages in the buying and
selling of crude oil to supply its refineries. The net results of this activity
are recorded in cost of sales. The Company also engages in the buying and
selling of refined products to facilitate the marketing of its refined products.
The results of this activity are recorded in cost of sales and sales.

Refined product exchange transactions that do not involve the payment or
receipt of cash are not accounted for as purchases or sales. Any resulting
volumetric exchange balances are accounted for as inventory in accordance with
the Company's last-in, first-out ("LIFO") inventory method. Exchanges that are
settled through payment or receipt of cash are accounted for as purchases or
sales.

Excise Taxes -- The Company collects excise taxes on sales of gasoline and
other motor fuels. Excise taxes of approximately $3 billion, $3.2 billion, and
$2.7 billion were collected from customers and paid to various governmental
entities in 1998, 1997, and 1996, respectively. Excise taxes are not included in
sales.

Cash and Cash Equivalents -- Cash and cash equivalents consist of
highly-liquid short-term investments and bank deposits with initial maturities
of three months or less.

Restricted Cash -- Restricted cash represents highly-liquid, short-term
investments held in trust accounts in accordance with a tax-exempt bond
agreement. Funds are released solely for financing construction of environmental
facilities as defined in the bond agreements.

Inventories -- Crude oil and refined product inventories are stated at the
lower of cost or market and cost is determined using the LIFO method. Materials
and supplies are valued using the average cost method.

Property, Plant and Equipment -- Property, plant and equipment is reported
at cost, less accumulated depreciation. Depreciation is based upon the estimated
useful lives of the related assets using the straight-line method. Depreciable
lives are generally as follows: buildings and leaseholds -- 10 to 24 years;
machinery and equipment -- 5 to 24 years; and vehicles -- 3 to 10 years.

Upon disposal or retirement of property, plant and equipment, the cost and
related accumulated depreciation are removed from the accounts and any resulting
gain or loss is recognized in income.

The Company capitalizes interest on projects when construction entails
major expenditures over extended time periods. Such interest is allocated to
property, plant and equipment and amortized over the estimated useful lives of
the related assets. Interest capitalized totaled $5 million, $7 million, and $12
million during 1998, 1997, and 1996, respectively.

Commodity and Interest Rate Derivatives -- The Company uses commodity and
financial instrument derivatives to manage defined commodity price and interest
rate risks arising out of the Company's core business activities. The Company
has only limited involvement with other derivative financial instruments and
does not use them for trading purposes.

The Company enters into petroleum futures contracts, options and other over
the counter commodity derivatives, primarily to hedge a portion of the price
risk associated with crude oil and refined products. In order for a transaction
to qualify for hedge accounting, the Company requires that the item to be hedged
exposes the Company to price risk and that the commodity contract reduces that
risk and is designated as a hedge. The high correlation between price movements
of a product and the commodity contract in that product is well demonstrated in
the petroleum industry and, generally, the Company relies on those historical
relationships and on periodic comparisons of market price changes to price
changes of futures and options contracts accounted for as hedges. Gains or
losses on contracts, which qualify as hedges, are recognized when the related
inventory is sold or the hedged transaction is consummated. Changes in the
market value of commodity derivatives, which are not hedges, are recorded as
gains or losses in the period in which they occur.
F-7

CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The Company also enters into various interest rate swap and cap agreements
to manage its risk related to interest rate changes on its debt. Premiums paid
for purchased interest rate swap and cap agreements are amortized to interest
expense over the terms of the agreements. Unamortized premiums are included in
other assets. The interest rate differentials received or paid by the Company
related to these agreements are recognized as adjustments to interest expense
over the term of the agreements. Gains or losses on terminated swap agreements
are either amortized over the original term of the swap agreement if the hedged
borrowings remain in place, or are recognized immediately if the hedged
borrowings are no longer held.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No. 133"). The statement establishes accounting
and reporting standards for derivative instruments and for hedging activities.
It requires that an entity recognize all derivatives, at fair value, as either
assets or liabilities in the statement of financial position with an offset
either to shareholder's equity and comprehensive income or income depending upon
the classification of the derivative. The Company has not determined the impact
on its financial statements that may result from adoption of SFAS No. 133, which
is required no later than January 1, 2000.

Refinery Maintenance -- Costs of major refinery turnaround maintenance are
charged to operations over the estimated period between turnarounds. Turnaround
periods range approximately from one to seven years. Unamortized costs are
included in other assets. Amortization of refinery turnaround costs is included
in depreciation and amortization expense. Amortization was $47 million, $49
million, and $53 million for 1998, 1997, and 1996, respectively. Ordinary
maintenance is expensed as incurred.

Environmental Expenditures -- Environmental expenditures that relate to
current or future revenues are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations and
do not contribute to current or future revenue generation are expensed.
Liabilities are recorded when environmental assessments and/or cleanups are
probable and the costs can be reasonably estimated. Environmental liabilities
are not discounted to their present value. Subsequent adjustments to estimates,
to the extent required, may be made as more refined information becomes
available.

Income Taxes -- The Company is included in the consolidated U.S. Federal
income tax return filed by PDV America. The Company's current and deferred
income tax expense has been computed on a stand-alone basis using an asset and
liability approach.

Comprehensive Income -- Effective January 1, 1998, the Company adopted
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income." The Company had no items of other comprehensive income during the three
years ended December 31, 1998.

Reclassifications -- Certain reclassifications have been made to the 1997
financial statements to conform with the classifications used in 1998.

2. REFINERY AGREEMENTS

Effective May 1, 1997, CITGO became the operator of a refinery owned by PDV
Midwest Refining, L.L.C. ("PDVMR"), a subsidiary of PDV America. CITGO also
purchases the products produced at the refinery (Note 4).

An affiliate of PDVSA acquired a 50 percent equity interest in a refinery
in Chalmette, Louisiana ("Chalmette") in October, 1997 and has assigned to CITGO
its option to purchase up to 50 percent of the refined products produced at the
refinery through December 31, 1999 (Note 4). CITGO exercised this option on
November 1, 1997, and acquired approximately 65 MBPD of refined products from
the refinery during 1998, approximately one-half of which was gasoline.

CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

In October, 1998 an affiliate of PDVSA acquired a 50 percent equity
interest in a joint venture that owns and operates a refinery in St. Croix, U.S.
Virgin Islands ("HOVENSA") and has the right under a product sales agreement to
assign periodically to CITGO, or other related parties, its option to purchase
50% of the refined products produced by HOVENSA (less a certain portion of such
products that HOVENSA will market directly in the local and Caribbean markets).
In addition, under the product sales agreement, the PDVSA affiliate has
appointed CITGO as its agent in designating which of its affiliates shall from
time to time take deliveries of the refined products available to it. The
product sales agreement will be in effect for the life of the joint venture,
subject to termination events based on default or mutual agreement (Note 4).
Pursuant to the above arrangement, CITGO began acquiring approximately 120 MBPD
of refined products from HOVENSA on November 1, 1998, approximately one-half of
which was gasoline.

3. INVESTMENT IN LYONDELL-CITGO REFINING LP

LYONDELL-CITGO Refining LP ("LYONDELL-CITGO") owns and operates a 265 MBPD
refinery in Houston, Texas. LYONDELL-CITGO was formed in 1993 by subsidiaries of
CITGO and Lyondell Chemical Company ("Lyondell"), referred to as the owners.
CITGO contributed cash for a participation interest and other commitments
related to LYONDELL-CITGO's refinery enhancement project and Lyondell
contributed the Houston refinery and related assets for the remaining
participation interest. The refinery enhancement project to increase the
refinery's heavy crude oil high conversion capacity was substantially completed
at the end of 1996 with an in-service date of March 1, 1997. The heavy crude oil
processed by the Houston refinery is supplied by a subsidiary of PDVSA under a
long-term crude oil supply contract that expires in 2017, and CITGO purchases
substantially all of the refined products produced at the Houston refinery under
a long-term contract (Note 4).

CITGO's participation interest in LYONDELL-CITGO increased from 13% at
December 31, 1996 to approximately 42% on April 1, 1997, in accordance with
agreements between the owners concerning such interest. CITGO has a one-time
option to increase, for an additional investment, its participation interest to
50 percent. This option may be exercised after January 1, 2000 but not later
than September 30, 2000.

CITGO loaned $19.8 million and $16.5 million to LYONDELL-CITGO during 1998
and 1997, respectively. The notes bear interest at market rates which were
approximately 5.9% at December 31, 1998 and 1997, and are due July 1, 2003.
These notes are included in other assets in the accompanying consolidated
balance sheets.

4. RELATED PARTY TRANSACTIONS

The Company purchases approximately two-thirds of the crude oil processed
in its refineries from subsidiaries of PDVSA under long-term supply agreements.
These supply agreements extend through the year 2006 for the Lake Charles
refinery, 2010 for the Paulsboro refinery, 2012 for the Corpus Christi refinery
and 2013 for the Savannah refinery. The Company purchased $1.4 billion, $2
billion, and $2.4 billion of crude oil, feedstocks and other products from
wholly owned subsidiaries of PDVSA in 1998, 1997, and 1996, respectively, under
these and other purchase agreements. The crude supply contracts include force
majeure clauses that have been exercised on various occasions. Exercise of these
clauses requires that the Company locate alternative sources of supply for its
crude oil requirements, and such action may result in lower operating margins.

The crude oil supply contracts incorporate formula prices based on the
market value of a number of refined products deemed to be produced from each
particular crude oil, less (i) certain deemed refining costs adjustable for
inflation, (ii) certain actual costs, including transportation charges, import
duties and taxes and (iii) a deemed margin, which varies according to the grade
of crude oil. At December 31, 1998 and 1997, $74 million and $138 million,
respectively, were included in payables to affiliates as a result of these
transactions.

The Company also purchases refined products from various other affiliates
including LYONDELL-CITGO, PDVMR, HOVENSA and Chalmette, under long-term
contracts. These agreements incorporate various formula prices based on
published market prices and other factors. Such purchases totaled $2.9 billion,
$2.8 billion, and $1.6 billion for 1998, 1997, and 1996, respectively. At
December 31, 1998 and 1997, $64 million and $59 million, respectively, were
included in payables to affiliates as a result of these transactions.

The Company had refined product, feedstock, and other product sales to
affiliates of $164 million, $221 million, and $190 million, in 1998, 1997, and
1996, respectively. The Company's sales of crude oil to affiliates were $18
million, $3 million, and $64 million in 1998, 1997, and 1996, respectively. At
December 31,

F-10
43
CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

1998 and 1997, $34 million and $23 million, respectively, were included in due
from affiliates as a result of these and related transactions.

Pursuant to the PDVMR operating agreement (Note 2), on May 1, 1997, CITGO
became the operator of the PDVMR refinery and employed a substantial number of
employees previously employed by UNO-VEN and as a result, CITGO assumed a
liability for postretirement benefits other than pensions (Note 11) of
approximately $27 million related to those employees. A corresponding amount due
from PDVMR is included in other assets at December 31, 1998 and 1997, pending
final determination of the method of settlement by the Parent company. CITGO
charges PDVMR a management fee which covers various support services ($8 million
and $7 million in 1998 and 1997, respectively) which is included in other
income. PDVMR reimburses CITGO for all payroll expenses, including pension and
benefit costs, related to CITGO employees engaged in the operation of the
refinery. Such employee costs and the related reimbursements ($52 million and
$36 million in 1998 and 1997, respectively) are not included in CITGO's cost of
sales or revenues.

Under a separate guarantee of rent agreement, PDVSA has guaranteed payment
of rent, stipulated loss value and terminating value due under the lease of the
Corpus Christi refinery facilities described in Note 14. The Company has also
guaranteed debt of certain affiliates (Note 13).

The Company and PDV America are parties to a tax allocation agreement that
is designed to provide PDV America with sufficient cash to pay its consolidated
income tax liabilities. In 1996, $12.7 million due from CITGO to PDV America
under this tax allocation agreement for the tax years 1992 through 1994 was
reclassified as a noncash contribution of capital. In December 1996, $0.8
million due from PDV America to CITGO under this tax allocation agreement for
the 1995 tax year was reclassified as a noncash dividend. In 1997, $10 million
due from PDV America under this tax allocation agreement for the 1996 tax year
was classified as a noncash dividend. In 1998, $7.6 million due from CITGO to
PDV America under this agreement for the 1997 tax year was classified as a
noncash contribution of capital. In the event that CITGO should cease to be part
of the consolidated federal income tax return, any amounts included in
shareholder's equity under this agreement are required to be paid to PDV
America. At December 31, 1998, CITGO has income taxes receivable of $12 million
included in prepaid expenses and a $5 million receivable from PDV America
included in due from affiliates. At December 31, 1997, amounts payable to PDV
America of $9.7 million are included in other current liabilities.

new limited purpose subsidiaries, CITGO Funding Corporation and CITGO Funding
Corporation II, which entered into non-recourse agreements to sell trade
accounts and credit card receivables. Under the terms of the agreements, new
receivables are added to the pool as collections reduce previously sold
receivables. The amounts sold at any one time are limited to a maximum of $125
million of trade accounts receivable and $150 million of credit card
receivables. These agreements are renewable for successive one-year terms by
mutual agreement. Both agreements were renewed during 1998. Fees and expenses of
$16.1 million and $5.8 million related to the agreements were recorded as other
expense during the years ended December 31, 1998 and 1997, respectively.
Proceeds of approximately $275 million from the initial sales in 1997 were used

and (ii) a $150 million, 364 day, revolving bank loan, both of which are
unsecured and have various borrowing maturities and interest rate options.
Interest rates on the revolving bank loans were 7.5 percent and 6.9 percent at
December 31, 1998 and 1997, respectively.

On September 3, 1998 the Company terminated its term bank loan.

Shelf Registration -- In April 1996, the Company filed a registration
statement with the Securities and Exchange Commission relating to the shelf
registration of $600 million of debt securities that may be offered and sold
from time to time. In May 1996, the registration became effective and CITGO sold
a tranche of debt securities with an aggregate offering price of $200 million.
On October 28, 1997, the Company entered into a Selling Agency Agreement with
Salomon Brothers Inc. and Chase Securities Inc. providing for the sale of up to
an additional $235 million in aggregate principal amount of notes in tranches
from time to time by the Company under the shelf registration. No amounts were
sold under this agreement as of December 31, 1998.

Private Placement -- At December 31, 1998, the Company has outstanding
approximately $177 million of privately placed, unsecured Senior Notes.
Principal amounts are payable in annual installments in November and interest is
payable semi-annually in May and November.

Master Shelf Agreement -- At December 31, 1998, the Company has outstanding
$260 million of privately-placed senior notes under an unsecured Master Shelf
Agreement with an insurance company. The notes have various fixed interest rates
and maturities.

Covenants -- The various agreements above contain certain covenants that,
depending upon the level of the Company's capitalization and earnings, could
impose limitations on the Company's ability to pay dividends, incur additional
debt, place liens on property, and sell fixed assets. The Company was in
compliance with the debt covenants at December 31, 1998.

Tax-Exempt Bonds -- Through state entities, the Company has issued $49.8
million of industrial development bonds for certain Lake Charles port facilities
and pollution control equipment and $226 million of environmental revenue bonds
to finance a portion of the Company's environmental facilities at its Lake
Charles and Corpus Christi refineries and at the LYONDELL-CITGO refinery.
Additional credit support for these bonds is provided through letters of credit.
The bonds bear interest at various floating rates which ranged from 4.1 percent
to 6 percent at December 31, 1998, and 3.7 percent to 5.2 percent at December
31, 1997.

Taxable Bonds -- Through state entities, the Company has issued and
currently outstanding $208 million of taxable environmental revenue bonds to
finance a portion of the Company's environmental facilities at its Lake Charles
refinery and at the LYONDELL-CITGO refinery. Such bonds are secured by letters
of credit and have floating interest rates (5.3 percent at December 31, 1998,
and 5.8 percent at December 31, 1997). At the option of the Company and upon the
occurrence of certain specified conditions, all or any portion of such taxable
bonds may be converted to tax-exempt bonds. At December 31, 1998, $12 million of
the original $120 million in taxable Louisiana revenue bonds had been converted
to tax-exempt bonds.

Cit-Con Bank Credit Agreement -- The Cit-Con bank credit agreement consists
of a term loan collateralized by throughput agreements of the owner companies.
The loan contains various interest rate options (weighted average effective
rates of 6.7 percent and 6.5 percent at December 31, 1998 and 1997,
respectively), and requires quarterly principal payments through December 2001.

Debt Maturities -- Future maturities of long-term debt as of December 31,
1998, are: 1999 -- $47.1 million, 2000 -- $47.1 million, 2001 -- $47.1 million,

11. EMPLOYEE BENEFIT PLANS

Employee Savings -- The Company sponsors three qualified defined
contribution retirement and savings plans covering substantially all eligible
salaried and hourly employees. Participants make voluntary contributions to the
plans and the Company makes contributions, including matching of employee
contributions, based on plan provisions. The Company expensed $19 million, $19
million, and $16 million related to its contributions to these plans for the
years 1998, 1997, and 1996, respectively.

Pension Benefits -- The Company sponsors three qualified noncontributory
defined benefit pension plans, two covering eligible hourly employees and one
covering eligible salaried employees. The Company also sponsors three
nonqualified defined benefit plans for certain eligible employees. The qualified
plans' assets include corporate securities and shares in a fixed income mutual
fund, two collective funds and a short-term investment fund. The nonqualified
plans are not funded.

The Company's policy is to fund the qualified pension plans in accordance
with applicable laws and regulations and not to exceed the tax-deductible
limits. The nonqualified plans are funded as necessary to pay retiree benefits.
The plan benefits for each of the qualified pension plans are primarily based on
an employee's years of plan service and compensation as defined by each plan.

Postretirement Benefits Other Than Pensions -- In addition to pension
benefits, the Company also provides certain health care and life insurance
benefits for eligible salaried and hourly employees at retirement. These
benefits are subject to deductibles, copayment provisions and other limitations
and are primarily funded on a pay as you go basis. The Company reserves the
right to change or to terminate the benefits at any time.

Actuarial gains (or losses) related to the postretirement benefit
obligation are recognized as a component of net postretirement benefit cost by
the amount the beginning of year unrecognized net gain (or loss) exceeds 7.5
percent of the accumulated postretirement benefit obligation.

The projected benefit obligation, accumulated benefit obligation, and fair
value of plan assets for the pension plan with accumulated benefit obligations
in excess of plan assets were $18.2 million, $17.5 million and $-0-,
respectively, as of December 31, 1998 and $16.2 million, $16 million and $-0-,
respectively, as of December 31, 1997.

Assumed health care cost trend rates have a significant effect on the
amounts reported for the health care plans. A one-percentage-point change in
assumed health care cost trend rates would have the following effects:

Employee Separation Programs -- During 1997, the Company's senior
management implemented a Transformation Program that resulted in certain
personnel reductions (the "Separation Programs"). The Company expensed
approximately $8 million and $22 million for the years ended December 31, 1998
and 1997, respectively, relating to the Separation Programs.

---- ---- ----

Federal statutory tax rate.................................. 35.0% 35.0% 35.0%

---- ---- ----
Effective tax rate.......................................... 34.6% 30.6% 35.6%
==== ==== ====


The effective tax rate for 1997 decreased due primarily to the favorable
resolution with the Internal Revenue Service of a significant tax issue related
to environmental expenditures. In 1998 the effective tax rate decreased slightly
compared to the 1996 rate due to a decrease in state taxes.

Deferred income taxes reflect the net tax effects of (i) temporary
differences between the financial and tax bases of assets and liabilities, and
(ii) loss and tax credit carryforwards. The tax effects of significant items
comprising the Company's net deferred tax liability as of December 31, 1998 and
1997, are as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

At December 31, 1998, the Company has capital loss carryforwards of $6.7
million, $2.5 million of which expire in 1999, $0.4 million of which expire in
2000, $2.3 million of which expire in 2001, and $1.5 million of which expire in
2002. At December 31, 1998 and 1997, a valuation allowance of $1.0 million and
$1.4 million was established related to that portion of the carryforwards for
which it was considered more likely than not that the related tax benefits would
not be realized before expiration.

The Company's alternative minimum tax credit carryforwards are available to
offset regular federal income taxes in future years without expiration, subject
to certain alternative minimum tax limitations.

13. COMMITMENTS AND CONTINGENCIES

Litigation and Injury Claims -- Various lawsuits and claims are pending
against the Company. The Company records accruals for potential losses when, in
management's opinion, such losses are probable and reasonably estimable. If
known lawsuits and claims were to be determined in a manner adverse to the
Company, and in amounts greater than the Company's accruals, then such
determinations could have a material adverse effect on the Company's results of
operations in a given reporting period. However, in management's opinion the
ultimate resolution of these lawsuits and claims will not exceed by a material
amount, the amount of the accruals and the insurance coverage available to the
Company. This opinion is based upon management's and counsel's current
assessment of these lawsuits and claims. The most significant lawsuits and
claims are discussed below.

In a pending case in federal court, Oil Chemical and Atomic Workers, Local
7-517 ("the Union") has asserted claims against CITGO, PDVSA, PDV America,
PDVMR, UNO-VEN and Unocal pursuant to the Labor Management Relations Act. The
Union alleges that CITGO and the other defendants are bound by the terms of a
collective bargaining agreement between UNO-VEN and the Union covering certain
employees at a refinery in Lemont, Illinois. This refinery was acquired by PDVMR
on May 1, 1997 in a transaction involving the former partners of UNO-VEN.
Pursuant to an operating agreement with PDVMR, CITGO became the operator of this
refinery and employed the substantial majority of the employees previously
employed by UNO-VEN pursuant to its initial terms and conditions of employment,
but CITGO did not assume the existing labor agreement. The Union seeks monetary
compensation for certain differences in employee benefits and reinstatement of
all of the UNO-VEN benefit plans. The union also seeks to require CITGO to abide
by the terms of the collective bargaining agreement between the Union and
UNO-VEN. In June 1998, the trial court granted the motions for summary judgment
filed by CITGO and the other defendants; the Union has appealed this ruling.

In May 1997, an explosion and fire occurred at CITGO's Corpus Christi
refinery. No serious personal injuries were reported. The Company received
approximately 7,500 individual claims for personal injury and property damage
related to the above noted incident. Approximately 1,300 of these claims have
been resolved for amounts which individually and collectively are not material.
There are presently six lawsuits pending against the Company in federal and
state courts alleging property damages, personal injury and punitive damages. A
trial in October 1998 involving ten bellwether plaintiffs, out of approximately
400 plaintiffs in one of the federal court lawsuits resulted in a verdict for
the Company. The trial of another ten plaintiffs is scheduled for February,
1999; the remaining cases are not currently scheduled for trial.

A class action lawsuit is pending in Corpus Christi, Texas state court
against the Company and other operators and owners of nearby industrial
facilities which claims damages for reduced value of residential properties
located in the vicinity of the industrial facilities as a result of air, soil
and groundwater contamination. In 1997, the Company offered to purchase about
275 properties in a neighborhood adjacent to the Company's Corpus Christi
refinery, which were included in the lawsuit. Related to this offer, $15.7
million was expensed in 1997. To date, the Company has reached agreements to buy
all but 18 of such properties, which include settlements of property damage
claims, and has offers open to purchase the remaining

F-20
53
CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

properties. Two related personal injury and wrongful death lawsuits were filed
against the same defendants in 1996 and are in preliminary stages of discovery.

Litigation is pending in federal court in Lake Charles, Louisiana, against
CITGO by a number of current and former Lake Charles refinery employees and
applicants on behalf of themselves and others asserting claims of racial
discrimination in connection with the Company's employment practices. The trial
court's denial of class certification has been upheld on appeal; the plaintiffs
are seeking review by the U.S. Supreme Court. Trials in this case are set for
fall, 1999.

Environmental Compliance and Remediation -- The Company is subject to
various federal, state and local environmental laws and regulations which may
require the Company to take action to correct or improve the effects on the
environment of prior disposal or release of petroleum substances by the Company
or other parties. Management believes the Company is in compliance with these
laws and regulations in all material aspects. Maintaining compliance with
environmental laws and regulations in the future could require significant
capital expenditures and additional operating costs.

In 1992, the Company reached an agreement with a state agency to cease
usage of certain surface impoundments at the Company's Lake Charles refinery by
1994. A mutually acceptable closure plan was filed with the state in 1993. The
Company and its former owner are participating in the closure and sharing the
related costs based on estimated contributions of waste and ownership periods.
The remediation commenced in December 1993. In 1997, the Company presented a
proposal to a state agency revising the 1993 closure plan. In 1998, the Company
amended its 1997 proposal as requested by the state agency. A ruling on the
proposal, as amended, is expected in 1999 with final closure to begin in 2000.

In 1992, an agreement was reached between the Company and its former owner
concerning a number of environmental issues. The agreement consisted, in part,
of payments to the Company totaling $46 million. The former owner will continue
to share the costs of certain specific environmental remediation and certain
tort liability actions based on ownership periods and specific terms of the
agreement.

Based on currently available information, including the continuing
participation of the former owner in remediation actions, management believes
its accruals for potential environmental liabilities are adequate. Conditions
which would require additional expenditures may exist for various Company sites
including, but not limited to, the Company's operating refinery complexes,
former refinery sites, service stations and crude oil and petroleum product
storage terminals. The amount of such future expenditures, if any, is
indeterminable.

Capital Expenditures -- The Company's anticipated capital expenditures,
excluding the investments in LYONDELL-CITGO, for the five-year period 1999 to
2003 total approximately $1.5 billion (unaudited). The expenditures include
environmental and regulatory capital projects as well as strategic capital
expenditures. At December 31, 1998, remaining authorized expenditures on
incomplete capital projects totaled approximately $269 million.

Supply Agreements -- CITGO purchases the crude oil processed at its
refineries and also purchases refined products to supplement the production from
its refineries to meet marketing demands and resolve logistical issues. In
addition to supply agreements with various affiliates (Note 4), the Company has
various other crude oil, refined product and feedstock purchase agreements with
unaffiliated entities with terms ranging from monthly to annual renewal. The
Company believes these sources of supply are reliable and adequate for its
current requirements.

Throughput Agreements -- The Company has throughput agreements with certain
pipeline affiliates (Note 8). These throughput agreements may be used to secure
obligations of the pipeline affiliates. Under these agreements, the Company may
be required to provide its pipeline affiliates with additional funds through
advances against future charges for the shipping of petroleum products. The
Company currently ships on these

F-21
54
CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

pipelines and has not been required to advance funds in the past. At December
31, 1998, the Company has no fixed and determinable, unconditional purchase
obligations under these agreements.

Commodity Derivative Activity -- The Company's commodity derivatives are
generally entered into through major brokerage houses and traded on national
exchanges and can be settled in cash or through delivery of the commodity. Such
contracts generally qualify for hedge accounting and correlate to market price
movements of crude oil and refined products. Resulting gains and losses,
therefore, will generally be offset by gains and losses on the Company's hedged
inventory or future purchases and sales. The Company's derivative commodity
activity is closely monitored by management and contract periods are generally
less than 30 days. Unrealized and deferred gains and losses on these contracts
at December 31, 1998 and 1997 and the effects of realized gains and losses on
cost of sales and pretax earnings for 1998, 1997, and 1996 were not material. At
times during 1998 and 1996, the Company entered into commodity derivatives
activities that were not related to the hedging program discussed above. This
activity and resulting gains and losses were not material in 1998 or 1996. There
was no non-hedging activity in 1997.

Other Credit and Off-Balance Sheet Risk Information as of December 31,
1998 -- The Company has guaranteed approximately $8 million of debt of certain
CITGO marketers. Such debt is substantially collateralized by assets of these
entities. The Company has also guaranteed approximately $99 million of debt of
certain affiliates, including $50 million related to HOVENSA (Note 2) and $11
million related to NISCO (Note 8). The Company has outstanding letters of credit
totaling approximately $520 million, which includes $500 million related to the
Company's tax-exempt and taxable revenue bonds (Note 10). The Company has also
acquired surety bonds totaling $42 million primarily due to requirements of
various government entities. The Company does not expect liabilities to be
incurred related to such guarantees, letters of credit or surety bonds.

Neither the Company nor the counterparties are required to collateralize
their obligations under interest rate swaps or caps or over-the-counter
derivative commodity agreements. The Company is exposed to credit loss in the
event of nonperformance by the counterparties to these agreements, but has no
off-balance sheet risk of accounting loss for the notional amounts. The Company
does not anticipate nonperformance by the counterparties, which consist
primarily of major financial institutions.

Management considers the market risk to the Company related to its
commodity and interest rate derivatives to be insignificant during the periods
presented.

14. LEASES

The Company leases certain of its Corpus Christi refinery facilities under
a capital lease. The basic term of the lease expires on January 1, 2004;
however, the Company may renew the lease until January 31, 2011, the date of its
option to purchase the facilities for a nominal amount. Capitalized costs
included in property, plant and equipment related to the leased assets were
approximately $209 million at December 31, 1998 and 1997. Accumulated
amortization related to the leased assets was approximately $102 million and $94
million at December 31, 1998 and 1997, respectively. Amortization is included in
depreciation expense.

The Company also has various noncancelable operating leases, primarily for
product storage facilities, office space, computer equipment and vehicles. Rent
expense on all operating leases totaled $34 million in 1998, $39 million in
1997, and $33 million in 1996. Future minimum lease payments for the capital
lease and noncancelable operating leases are as follows:

15. FAIR VALUE INFORMATION

The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of SFAS No. 107,
"Disclosures about Fair Value of Financial Instruments." The estimated fair
value amounts have been determined by the Company, using available market
information and appropriate valuation methodologies. However, considerable
judgment is necessarily required in interpreting market data to develop the
estimates of fair value. Accordingly, the estimates presented herein are not
necessarily indicative of the amounts that the Company could realize in a
current market exchange. The use of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.

The carrying amounts of cash equivalents, restricted cash and variable-rate
debt approximate fair values. The carrying amounts and estimated fair values of
the Company's other financial instruments are as follows:

CITGO PETROLEUM CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Short-term bank loans and long-term debt -- The fair value of short-term
bank loans and long-term debt is based on interest rates that are currently
available to the Company for issuance of debt with similar terms and remaining
maturities.

Interest rate swap and cap agreements -- The fair value of these agreements
is based on the estimated amount that the Company would receive or pay to
terminate the agreements at the reporting dates, taking into account current
interest rates and the current creditworthiness of the counterparties.

Guarantees, letters of credit and surety bonds -- The estimated fair value
of contingent guarantees of third-party debt, letters of credit and surety bonds
is based on fees currently charged for similar one-year agreements or on the
estimated cost to terminate them or otherwise settle the obligations with the
counterparties at the reporting dates.

The fair value estimates presented herein are based on pertinent
information available to management as of the reporting dates. Although
management is not aware of any factors that would significantly affect the
estimated fair value amounts, such amounts have not been comprehensively
revalued for purposes of these financial statements since that date, and current
estimates of fair value may differ significantly from the amounts presented
herein.
