ITEM 1. BUSINESS

GENERAL

     EOTT Energy Partners, L.P., a Delaware limited partnership, through its
affiliated limited partnerships, EOTT Energy Operating Limited Partnership, EOTT
Energy Canada Limited Partnership, and EOTT Energy Pipeline Limited Partnership,
is engaged in the purchasing, gathering, transporting, trading, storage and
resale of crude oil, refined petroleum products, natural gas liquids and related
activities. EOTT Energy Partners, L.P. has changed its principal business
segments and has restated segment information for earlier periods. EOTT Energy
Partners, L.P.'s principal business segments are its North American - East of
Rockies crude oil gathering and marketing operations, its Pipeline Operations
and its West Coast Operations, which includes crude oil gathering and marketing,
refined products marketing and a natural gas liquids business (see Note 19 to
the Consolidated Financial Statements for certain financial information by
business segment). Unless the context otherwise requires, the terms "EOTT" and
the "Partnership" herein refer to EOTT Energy Partners, L.P., its affiliated
limited partnerships, and for periods prior to the Partnership's initial public
offering in March 1994, EOTT Energy Corp., its wholly-owned subsidiary, EOTT
Energy Ltd., and its affiliated company, Enron Products Marketing Company
(collectively referred to as the "Predecessor").

     EOTT Energy Corp. (the "General Partner"), a Delaware corporation and an
indirect wholly-owned subsidiary of Enron Corp. ("Enron"), serves as the sole
general partner of the Partnership and its affiliated operating limited
partnerships. In addition to its aggregate approximate 2% general partner
interest in the Partnership, the General Partner owns an approximate 29% limited
partner interest in the Partnership in the form of subordinated units. Enron,
through its ownership of EOTT Common Units, more fully described in Note 1 to
the Consolidated Financial Statements, holds an approximate 14% interest in the
Partnership.

OVERVIEW

     On December 1, 1998, the Partnership purchased certain crude oil gathering
and transportation assets in key oil producing regions from Koch Pipeline
Company, L.P., a subsidiary of Koch Industries, Inc., and Koch Oil Company, a
division of Koch Industries, Inc. (collectively "Koch"). The transaction almost
tripled EOTT's pipeline mileage, almost doubled crude oil lease barrels under
contract and should strengthen profitability and cash flow. The acquisition
included approximately 3,900 miles of crude oil pipelines, crude oil transport
trucks, meter stations, vehicles, storage tanks and contracts for approximately
180,000 lease barrels of crude oil per day from production in 11 central and
western states including Texas, Oklahoma, Kansas and California (the "Assets").

     As an intermediary, EOTT seeks to earn profits primarily by buying crude
oil at competitive prices, efficiently transporting and handling the purchased
crude oil and marketing the crude oil to refinery customers or other trade
partners who can most benefit from the particular crude type. Through its crude
oil gathering and marketing operations, EOTT purchases crude oil produced from
approximately 40,000 leases in 18 states and is also a major purchaser of lease
crude oil in Canada. In addition to its gathering and marketing operations, EOTT
has pipeline operations which transport crude oil on intrastate and interstate
pipelines based on regulated published tariffs.

     In its crude oil gathering and marketing operations, EOTT purchases crude
oil from many of the largest integrated and independent crude oil producers in
the United States and Canada. Approximately 87% of EOTT's lease crude oil is
purchased from independent oil producers, and approximately 13% is purchased
from major 

                                       3
<PAGE>   4

integrated oil companies ("majors"). EOTT markets the crude oil to majors and
independent refiners throughout the United States and Canada. EOTT was
purchasing approximately 270,700 barrels per day ("bpd") of lease crude oil
prior to the acquisition of Assets from Koch. In December 1998, after the
acquisition of Assets from Koch, EOTT purchased approximately 450,200 bpd of
lease crude oil. EOTT's pipeline systems and trucking operations provide the
vital link between the crude oil purchasing and marketing activities. Within the
United States, EOTT transports most of the lease crude oil it purchases with its
trucking operations, a fleet of 440 owned or leased trucks, and by pipelines,
including approximately 6,200 miles of active intrastate and interstate pipeline
and gathering systems owned by EOTT, as well as common carrier pipeline systems
owned by third parties. In addition, EOTT provides transportation and marketing
services for third party purchasers of crude oil. These pipeline systems and
trucking operations cover 18 states: Alabama, Arkansas, California, Colorado,
Florida, Kansas, Louisiana, Mississippi, Missouri, Nebraska, New Mexico,
Oklahoma, Texas, Utah, Wyoming, Montana, North Dakota, and South Dakota.

NORTH AMERICAN CRUDE OIL - EAST OF ROCKIES OPERATIONS

     In its North American Crude Oil - East of Rockies gathering and marketing
business, EOTT purchased approximately 428,000 bpd of lease crude oil in
December 1998. EOTT purchases lease crude oil barrels at prevailing market
prices. Generally, as EOTT purchases lease barrels, it simultaneously enters
into a corresponding sale transaction involving physical deliveries of crude oil
to third party users, such as refiners or other trade partners, or a sale of
futures contracts on the New York Mercantile Exchange ("NYMEX"). This process
gives EOTT the opportunity to secure a profit on the transaction at the time of
purchase and to minimize or eliminate exposure to price fluctuations occurring
after the initial purchase. EOTT effects transactions both in the futures and
physical markets in order to deliver the crude oil to its highest value location
or otherwise to maximize the value of the crude oil controlled by EOTT.
Throughout the process, EOTT seeks to maintain a substantially balanced position
at all times; however, EOTT has certain basis risks (the risk that price
relationships between delivery points, grades of crude oil or delivery periods
will change) which cannot be completely hedged. It is EOTT's policy not to
acquire and hold crude oil, other petroleum products, futures contracts or other
derivative products for the purpose of speculating on price changes.

     While EOTT engages in several types of purchases, sales and exchanges of
crude oil, most transactions entered into by EOTT are at market responsive
prices for a term or duration of 90 days or less, with a large number of EOTT's
transactions done on a 30-day evergreen basis. These purchases are automatically
renewable on a month-to-month basis until terminated by either party. The
purchases are based on market related indices, which change frequently in
response to market changes. Conducting business on this basis helps EOTT reduce
the risk in its North American crude oil gathering and marketing business.

     The marketing of crude oil is complex and requires detailed current
knowledge of crude oil sources and outlets and a familiarity with a number of
factors including: types of crude oil, individual refinery demand for specific
grades of crude oil, area market price structures for the different grades of
crude oil, location of customers, availability of transportation facilities, and
timing and costs (including storage) involved in delivering crude oil to the
appropriate customer. EOTT engages in marketing transactions that have the
potential to enhance the value of the crude oil EOTT purchases.

     The purchase and resale of crude oil is a highly competitive activity with
very thin and volatile profit margins. Purchasers of crude oil at the lease
compete on the basis of being able to provide competitive prices and highly
responsive customer service. EOTT believes its ability to offer quality service
to producers is a key factor in maintaining lease purchase volumes and in
obtaining new volumes. Services offered by EOTT include gathering capabilities,
timely pickup of crude oil from tank batteries at the lease or production point,
accurate measurement of crude oil volumes delivered, avoidance of spills, and
certain accounting and administrative services. Accounting and administrative

                                       4
<PAGE>   5

services include securing division orders (statements affirming the division of
ownership in lease crude oil purchased by EOTT), providing statements of the
crude oil purchased each month, disbursing production proceeds to interest
owners, and calculation and payment of severance and production taxes on behalf
of interest owners. In order to compete effectively, EOTT must handle title and
division order issues in a professional and timely manner, thereby ensuring the
prompt and correct processing or payment of crude oil production proceeds,
together with the correct handling or payment and regulatory reporting of all
severance and production taxes associated with such proceeds.

PIPELINE OPERATIONS

     EOTT's Pipeline Operations include approximately 5,300 miles of active
intrastate and interstate regulated pipelines and in December 1998, EOTT's
Pipeline Operations transported approximately 363,000 bpd through its regulated
pipeline systems. Through these pipeline systems, EOTT transports crude oil for
the North American Crude Oil - East of Rockies business segment, West Coast
Operations business segment and other third party customers pursuant to
published tariff rates regulated by the Federal Energy Regulatory Commission
("FERC") and state regulatory authorities. Accordingly, EOTT offers
transportation services to any shipper of crude oil, provided that the crude oil
meets the conditions and specifications contained in the applicable pipeline
tariff. Pipeline Operations revenues are primarily a function of the level of
crude oil transported through the pipeline, known as throughput, and the
applicable pipeline tariffs. The operating income from EOTT's Pipeline
Operations is generated by the difference between the published tariff and the
fixed and variable costs of operating the pipelines. Approximately 78% of the
Pipeline Operations' revenues in 1998 were generated from tariffs charged to
EOTT's North American Crude Oil - East of Rockies business segment.

WEST COAST OPERATIONS

     EOTT conducts three distinct business activities in the petroleum market on
the West Coast: crude oil gathering and marketing, natural gas liquids ("NGLs")
marketing, and refined petroleum products marketing.

     EOTT's activity in crude oil gathering and marketing represents the bulk of
the net income generated from the West Coast Operations. EOTT's margins for its
West Coast crude oil business are primarily tied to EOTT's ability to upgrade
heavy sour crude oil into a medium gravity, Alaskan North Slope ("ANS") type of
crude oil, called Line 63 Blended Crude. To accomplish this, EOTT gathers crude
oil by truck and pipeline and delivers it to proprietary blend stations
strategically placed along an EOTT owned gathering system. EOTT's strategy is to
maintain an optimum supply of blended crude oil necessary to meet its sales
commitments to Los Angeles Basin refiners. Approximately 40,000 bpd of Line 63
Blended Crude is shipped by EOTT to Los Angeles Basin refineries.

     The acquisition of assets from Koch added approximately 15,000 bpd to the
West Coast crude oil volumes gathered by EOTT from the lease and these leases
are pipeline connected to blending facilities obtained from Koch. The major
portion of these newly acquired crude oil lease barrels is light crude. This
light crude, together with other components, results in up to 20,000 bpd of Line
63 Blended Crude. The crude oil assets acquired by EOTT from Koch on the West
Coast included three blend stations or tank farms; nine trucks; approximately
300 miles of active pipeline connected to predominately light crude oil fields;
and direct connections to Arco's Line 63 Pipeline and the All American Pipeline.

     Strategies to use these assets include expanding throughput with majors,
refiners and crude oil producers. Additionally, these gathering assets will
permit EOTT to move crude oil north or south for delivery to the majors at the
most competitive economics.


                                       5
<PAGE>   6

     The acquisition of assets from Koch greatly expanded EOTT's existing NGL
marketing business on the West Coast. Assets acquired by EOTT from Koch for the
NGL business primarily included a gas processing plant referred to as Plant 8,
with 20 million cubic feet per day of gas processing capacity and a
fractionation plant with 8,000 bpd of fractionation capacity and 5 million
gallons of refrigerated propane storage along with related distribution
facilities. EOTT's NGL strategy is to increase throughput for the gas and
fractionation plants as margins associated with these assets are primarily
generated by processing throughput for others for a fee.

     In addition, the West Coast Operations include a refined petroleum products
marketing business. This business specializes mostly in marketing distillate and
gasoline, including at terminals located between Seattle and San Diego.

RISK MANAGEMENT SERVICES / DERIVATIVES

     Sophisticated price risk management strategies, including those involving
price hedges using NYMEX futures contracts, are becoming increasingly important
in creating and maintaining intermediary margins. Such hedging techniques
require significant resources dedicated to the management of futures positions -
a capability that many smaller purchasers do not have. EOTT's risk management
personnel coordinate all of EOTT's NYMEX trading activities and other hedging
techniques to ensure that EOTT's hedging activities are meeting EOTT's
objectives. At the same time, this enables EOTT to net positions internally and
reduces overall volumes and associated commissions. The consolidation of price
risk management activities not only allows for more efficient hedging and
futures trading, but also provides marketers of physical volumes the freedom to
focus on their markets.

CREDIT

     Credit review and analysis are integral to EOTT's overall business. When
EOTT purchases crude oil at the lease, EOTT often makes payment for all or
substantially all of the crude oil production to one party (usually the operator
of the lease). The operator, in turn, is responsible for the correct payment and
distribution of such crude oil production proceeds to all parties who own an
interest in such funds. In these situations, EOTT must make sure that the
operator is creditworthy and able to indemnify and defend EOTT in the event any
third party should bring a protest, action or complaint in connection with the
ultimate distribution of crude oil production proceeds by the operator. In
addition, when EOTT markets crude oil, natural gas liquids or other petroleum
products, EOTT must determine the amount, if any, of the line of credit to be
extended to any given customer. Since typical EOTT sales transactions can
involve several thousand barrels of crude oil or product, the risk of
non-payment and non-performance by customers is a major consideration in EOTT's
business. Likewise, EOTT's credit standing is a major consideration for parties
with whom EOTT does business. At times, EOTT may furnish and receive letters of
credit to and from its business counterparties. The cost of furnishing letters
of credit and/or guarantees can be substantial. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -Working Capital and
Credit Resources."

COMPETITION

     In the various business and marketing activities described above, EOTT is
in competition with major oil companies and a larger number of smaller entities.
The number and location of EOTT's pipeline systems and trucking facilities give
EOTT access to a substantial volume of domestic crude oil production throughout
the crude oil producing areas of the United States. EOTT also has considerable
flexibility in disposing of the volumes of crude oil that it purchases, without
dependence on any single customer or transportation or storage facility. EOTT's
principal competitors in the purchase of leasehold crude oil production are
Scurlock Permian 

                                       6
<PAGE>   7

Oil Corporation, Equiva (formerly Texaco Trading & Transportation Co., Inc.),
Amoco Oil Company (and related affiliates), Sun Refining & Marketing, and TEPPCO
(formerly part of Duke Energy). Competitive factors include price, quality of
service, transportation facilities, financial strength, and knowledge of
products and markets.

     There are a number of major structural and economic changes impacting all
of EOTT's market segments that are driving new customer needs, changing
competitor dynamics and, consequently, creating new challenges and opportunities
for responsive market participants. The crude oil gathering and marketing
business is characterized by thin, volatile margins and intense competition for
supplies of lease crude oil. The decline in domestic crude oil production has
made competition among gatherers and marketers even more intense.

ENVIRONMENTAL MATTERS

     EOTT is subject to federal, state and local laws and regulations relating
to the protection of the environment. At the federal level, such laws include,
among others, the Clean Air Act, the Clean Water Act, the Oil Pollution Act, the
Resource Conservation and Recovery Act, the Comprehensive Environmental
Response, Compensation and Liability Act, and the National Environmental Policy
Act, as each may be amended from time to time. Compliance with such laws and
regulations in the future could prove to be costly, and there can be no
assurance that EOTT will not incur such costs in material amounts.

     The Clean Air Act controls, among other things, the emission of volatile
organic compounds, nitrogen oxides, and all other ozone-producing compounds in
order to protect national ambient air quality in accordance with standards
established for ozone and other pollutants. Such emissions may occur from the
handling or storage of petroleum or natural gas. The sources of emissions that
are subject to control and the types of controls required are a matter of
individual state air quality control implementation plans that set forth
emission limitations. Both federal and state laws impose substantial civil and
even criminal penalties for violation of applicable requirements. As part of the
regular overall evaluation of its current operations, EOTT is updating the
operating permit status of certain of its recently acquired properties. EOTT
believes that its overall operations are in substantial compliance with
applicable air requirements.

     The Clean Water Act, as amended by the Oil Pollution Act of 1990 ("OPA"),
controls, among other things, the discharge of oil and other petroleum products
into waters of the United States. The Clean Water Act provides penalties for any
unauthorized discharges of pollutants (including petroleum products) into waters
of the United States and imposes substantial potential liability for the costs
of responding to an unauthorized discharge of pollutants, such as an oil spill.
State laws for the control of water pollution also provide varying civil and
criminal penalties and liabilities in the case of a release of petroleum or
other related products in surface waters or into the ground. Federal and state
permits for water discharges may be required.

     OPA also imposes a variety of requirements on "responsible parties" for oil
and gas facilities related to the prevention of oil spills and liability for
damages resulting from such spills in waters of the United States. The term
"responsible party" includes the owner or operator of an oil or gas facility
that could be the source of an oil spill affecting jurisdictional waters of the
United States. OPA assigns liability to each responsible party for oil spill
removal costs and a variety of public and private damages from oil spills. OPA
establishes a liability limit for onshore facilities of up to $350 million while
the limit for offshore facilities is all removal costs plus up to $75 million in
other damages. A party cannot take advantage of liability limits, however: if
the spill is caused by gross negligence or willful misconduct, if the spill
resulted from violation of a federal safety, construction or operating
regulation or if a party fails to report a spill or to cooperate fully in the
cleanup. Few defenses exist to the liability for oil spills imposed by OPA. OPA
also imposes other requirements on facility operators, such as the preparation
of an oil spill response plan, and a demonstration of the operator's ability to
pay for 

                                       7
<PAGE>   8

environmental cleanup and restoration costs likely to be incurred in connection
with an oil spill. For onshore facilities that have the ability to affect waters
of the United States, recent amendments to OPA require an operator to
demonstrate $10 million in financial responsibility, and $35 million in
financial responsibility for offshore facilities. On August 11, 1998, the U.S.
Minerals Management Service ("MMS") promulgated a final rule implementing the
financial responsibility requirements set forth under the OPA amendments. The
financial responsibility may be increased to a maximum of $150 million if the
MMS determines that a greater amount is justified based on specific risks posed
by the operations or if the worst case oil-spill discharge volume possible at
the facility may exceed the applicable threshold volumes specified under the MMS
final rule. The General Partner fully anticipates that EOTT will be able to
satisfy the MMS's requirements for financial responsibility under OPA, as
amended, and the final rule. Failure to comply with these OPA requirements or
inadequate cooperation in a spill event may subject a responsible party to civil
or criminal actions.

     EOTT generates wastes, including hazardous wastes, that are subject to the
federal Resources Conservation and Recovery Act ("RCRA") and comparable state
statutes. The U.S. Environmental Protection Agency ("EPA") and various state
agencies have limited the approved methods of disposal for certain hazardous and
nonhazardous wastes. Furthermore, certain wastes generated by EOTT that are
currently exempt from treatment as "hazardous wastes" may in the future be
designated as "hazardous wastes" and therefore be subject to more rigorous and
costly operating and disposal requirements.

     The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without regard
to fault or the legality of the original conduct, on certain classes of persons
that are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances that have been
released at the site. Persons who are or were responsible for releases of
hazardous substances under CERCLA may be subject to joint and several liability
for the costs of cleaning up the hazardous substances that have been released
into the environment and for damages to natural resources, and it is not
uncommon for neighboring landowners and other third parties to file claims for
personal injury and property damage allegedly caused by the hazardous substances
released into the environment. In the ordinary course of EOTT's operations,
substances may be generated that fall within the definition of "hazardous
substances." Moreover, EOTT may own or operate properties that in the past were
operated by third parties whose operations were not under EOTT's control. Those
properties and any wastes that may have been disposed on them may be subject to
CERCLA, RCRA and analogous state laws, and EOTT potentially could be required to
remediate such properties.

     EOTT potentially may have liability under CERCLA and similar state laws at
three known sites. In 1991, EOTT took a deed of trust on the Rattlesnake
refinery in Wickett, Texas, to secure delinquent accounts payable by the owner
of the refinery. The refinery had numerous operational problems and ceased
operating in 1992. Environmental contamination is known to exist at the
refinery, but EOTT cannot estimate the extent of the contamination and the
potential costs of remediation. EOTT's management believes that EOTT would not
be considered an owner or operator of the refinery and that EOTT does not have
any responsibility with respect to the environmental conditions at the
Rattlesnake refinery. Nevertheless, the potential liability, if any, of EOTT
with respect to this site cannot be predicted at this time.

     In 1987, EOTT purchased a crude oil terminal and transportation facility
from Fairway Crude, Inc. This facility is adjacent to the Mid-America Refining
Company site in Chanute, Kansas. The Mid-America refinery ceased operations in
1981, and environmental contamination is known to exist at the refinery site.
EOTT cannot estimate the extent of contamination or the potential costs of
remediation associated with the Mid-America refinery. In 1993, EOTT received a
request for information from the EPA that suggests the EPA believes EOTT may be
potentially responsible for the costs of remediating some contamination at the
Mid-America refinery site. 

                                       8
<PAGE>   9

Since EOTT did not purchase the adjacent facility until 1987 and EOTT has been
careful to avoid contamination of its property, the General Partner believes
that EOTT should not be responsible for remediating environmental conditions at
the Mid-America refinery site. Nevertheless, the potential liability, if any, of
EOTT with respect to this site cannot be predicted at this time.

     In early 1991, EOTT entered into a crude oil processing agreement with a
California refiner pursuant to which EOTT's crude oil was processed into refined
petroleum products during 1991 and 1992. On December 31, 1992, EOTT entered into
a new, long-term processing agreement that replaced the agreement in effect
during 1991 and 1992. This latter agreement was terminated in September 1995 in
connection with the termination of EOTT's West Coast processing and asphalt
marketing business. The General Partner has been advised by the refiner that
environmental conditions exist in the area of the refinery, including soil and
groundwater contamination, that are the subject of ongoing, long-term
remediation. Conditions of this nature are frequently associated with petroleum
refineries. These conditions existed prior to EOTT's original processing
agreement and prior to the acquisition of the refinery by the current owners.
The General Partner has been advised that the refiner is implementing
groundwater and soil remediation that includes retrieval and treatment of the
contaminated groundwater and is preparing a long-term groundwater and soil
remedial action plan. The General Partner understands that the refiner is
working with the regulatory agencies in effecting this remediation.

     It is possible that EOTT could be named as a defendant in any legal action
that might be filed as a consequence of environmental conditions associated with
the California refinery, although the General Partner believes that valid
defenses exist to any claim that may be filed with respect to existing
environmental conditions. The General Partner cannot predict the nature or size
of future claims that might be filed as a consequence of environmental
conditions in the area of the refinery. The likelihood of such a claim against
EOTT could be increased if the refiner is unable to complete its environmental
cleanup and compliance program. In addition, because land surrounding the
refinery is devoted to residential, commercial and industrial uses, there may be
increased sensitivity within the local community to environmental issues
concerning the operations of the refinery. The General Partner can give no
assurances as to how courts or regulatory authorities will, in the future,
interpret or apply the liability provisions of applicable law, including federal
or state environmental laws and regulations.

     The National Environmental Policy Act ("NEPA") may apply to certain
extensions or additions to a pipeline system. Under NEPA, if any project is to
be undertaken which would significantly affect the quality of the environment
and require a permit or approval from a federal agency, the federal agency may
require preparation of a detailed environmental impact study. The issuance by a
federal agency of a permit or approval to construct or extend a pipeline system
may constitute a major federal action under this Act. The effect of NEPA may be
to delay or prevent construction of new facilities or to alter their location,
design or method of construction.
Similar state laws may also be applicable.

     In addition to the foregoing, EOTT is subject to state environmental laws
and regulations that address environmental considerations that may be of
particular concern to a state.

     The management of EOTT believes that there are no outstanding potential
liabilities or claims relating to safety and environmental matters the
resolution of which, individually or in the aggregate, would have a materially
adverse effect on EOTT's financial position or results of operations and that
EOTT has used reasonably diligent efforts to comply, in all material respects,
with all applicable environmental laws and regulations. No assurance can be
given, however, as to the amount or timing of future expenditures for
environmental remediation or compliance, and actual future expenditures may be
different from the amounts currently anticipated. In the event of future
increases in costs, EOTT may be unable to pass on those increases to its
customers.

REGULATION

     EOTT is subject to a variety of federal and state regulations relating to
its interstate and intrastate pipeline transportation and safety activities,
motor carrier activities, and commodities trading business, the most significant
of which are discussed below.

Pipeline FERC Regulation

     Interstate Regulation Generally. EOTT's interstate common carrier pipeline
operations are subject to rate regulation by the FERC under the provisions of
the Interstate Commerce Act ("ICA"). These operations include the Hobbs pipeline
in New Mexico and Texas, the crude oil system in Mississippi and Alabama ("the
Mississippi-Alabama Pipeline"), the crude oil systems acquired from CITGO
Pipeline Company ("CITGO Pipelines"), and portions of the crude oil systems
acquired from Koch Pipeline, L.P. ("Koch Pipelines"). The ICA requires, among
other things, that petroleum pipeline rates be just and reasonable and
non-discriminatory. The ICA permits interested parties to challenge proposed new
or changed rates and authorizes the FERC to suspend the effectiveness of such
rates for a period of up to seven months and to investigate such rates. If, upon
the completion of an investigation, the FERC finds that the new or changed rate
is unlawful, it is authorized to require the carrier to refund the revenues
collected during the pendency of the investigation in excess of those that would
have been collected under the prior tariff. In addition, the FERC, upon
complaint or on its own motion and after investigation, may order a carrier to
change its rate prospectively. Upon an appropriate showing, a shipper may obtain
reparations for damages sustained for a period of up to two years prior to the
filing of a complaint.

     EOTT has annually amended its tariffs on all of its regulated pipelines as
provided by FERC regulations effective July 1 of 1995, 1996, 1997, and 1998.
Although no assurance can be given that the tariffs charged by EOTT will
ultimately be upheld if challenged, EOTT believes that the tariffs now in effect
for all of its pipelines are within the maximum rates allowed under the current
FERC guidelines.

     Energy Policy Act of 1992 and Subsequent Developments. In October 1992,
Congress passed the Energy Policy Act of 1992, which, among other things,
required the FERC to issue rules establishing a simplified and generally
applicable ratemaking methodology for petroleum pipelines and to streamline
procedures in petroleum pipeline proceedings. The FERC responded to this mandate
by issuing several orders, including Order No. 561. Beginning January 1, 1995,
Order No. 561 enables petroleum pipelines to change their rates within
prescribed ceiling levels that are tied to an inflation index. Rate increases
made pursuant to the indexing methodology are subject to protest, but such
protests must show that the portion of the rate increase resulting from
application of the index is substantially in excess of the pipeline's increase
in costs. If the indexing methodology results in a reduced ceiling level that is
lower than a pipeline's filed rate, Order No. 561 requires the pipeline to
reduce its rate to comply with the lower ceiling. A pipeline must, as a general
rule, utilize the indexing methodology to change its rates. The FERC, however,
retained cost-of-service ratemaking, market-based rates, and settlement as
alternatives to the indexing approach, which alternatives may be used in certain
specified circumstances. In addition to the regulatory considerations noted
above, it is expected that the Hobbs, Mississippi-Alabama, CITGO, and Koch
Pipelines tariff rates will continue to be constrained by competitive and other
market factors.

     State Regulation. EOTT's intrastate pipeline transportation activities are
subject to various state laws and regulations, as well as orders of regulatory
bodies pursuant thereto.

     Petroleum Pipeline Safety Regulation. EOTT's petroleum pipelines are
subject to regulation by the Department of Transportation with respect to the
design, installation, testing, construction, operation, replacement, and
management of pipeline facilities. In addition, EOTT must permit access to and
copying of 


                                       10
<PAGE>   11

records, and to make certain reports and provide information as required by the
Secretary of Transportation. Comparable regulation exists in some states in
which EOTT conducts intrastate common carrier or private pipeline operations.

     Pipeline safety issues are currently receiving significant attention in
various political and administrative arenas at both the state and federal
levels. Significant expenses could be incurred if additional safety requirements
are imposed that exceed the current pipeline control system capabilities.

Trucking Regulation

     EOTT operates its fleet of trucks as a private carrier. Additionally, in
Louisiana and California it is engaged in contract carrier hauling of crude oil
and natural gas liquids for third parties, and in Oklahoma it hauls salt water
and other fluids for others. Although a private carrier that transports property
in interstate commerce is not required to obtain operating authority from the
Surface Transportation Board, the carrier is subject to certain motor carrier
safety regulations issued by the Department of Transportation. The trucking
regulations extend to driver operations, keeping of log books, truck manifest
preparations, safety placards on the trucks and trailer vehicles, drug and
alcohol testing, safety of operation and equipment, and many other aspects of
truck operations. EOTT is also subject to Occupational Safety and Health
Administration ("OSHA") regulations with respect to its trucking operations.

     EOTT provides contract carrier service in Louisiana pursuant to a permit
issued by the Louisiana Public Service Commission. Louisiana contract carriers
are also subject to certain safety regulations related to service and
operations.

Commodities Regulation

     EOTT's price risk management operations are subject to constraints imposed
under the Commodity Exchange Act (the "CEA"). The futures and options contracts
that are traded on the NYMEX are subject to strict regulation by the Commodity
Futures Trading Commission (the "CFTC"). Although NYMEX futures contracts
include contracts on sweet crude oil, No. 2 heating oil and other refined
petroleum products, there are many products that EOTT will purchase and sell for
which no futures contracts are available, due in part to the strict regulatory
scheme for futures contracts. In addition, the trading volumes and pricing bases
of futures contracts on some products are such that the ability to use them to
hedge EOTT's price risks may be limited.

Other Regulation

     After exiting the East of Rockies refined products business, EOTT primarily
markets refined gasoline at the wholesale level in 4 states. EOTT markets both
reformulated and conventional gasoline in ozone nonattainment areas during
control periods. EOTT is subject to extensive federal and state laws and
regulations governing product specifications, transfer documentation, record
keeping and sampling. Many of these laws and regulations impose significant
financial penalties for non-compliance.

grades of crude oil and the resulting changes in pricing relationships,
developments relating to possible acquisitions or business combination
opportunities, industry conditions, the ability of the Partnership to avoid
environmental liabilities, developments at FERC relating to pipeline tariff
regulation, the successful resolution of litigation, the success of the
Partnership's risk management activities and conditions of the capital markets
and equity markets during the periods covered by the forward-looking statements.
Although the Partnership believes that its expectations regarding future events
are based on reasonable assumptions, it can give no assurance that these are all
the factors that could cause actual results to vary materially from the
forward-looking statements or that its expectations regarding future
developments will prove to be correct.


ITEM 2. PROPERTIES

PIPELINE AND TRANSPORTATION ASSETS AND PROPERTIES

     At year end 1998, EOTT owned and operated 6,200 miles of active crude oil
gathering and transmission pipelines, including the assets acquired from Koch
Pipeline Company, L.P. discussed below, covering fourteen states (Alabama,
Arkansas, California, Louisiana, Mississippi, New Mexico, Oklahoma, Texas,
Kansas, Nebraska, Colorado, Montana, North Dakota, and South Dakota), including
5,300 miles of regulated intrastate and interstate common carrier pipeline
systems located in Alabama, Louisiana, Mississippi, Texas, New Mexico, Oklahoma,
Kansas, Nebraska, Colorado, California, Montana, North Dakota, and South Dakota.
There are approximately 9.2 million barrels of storage capacity associated with
these pipelines and field tanks. EOTT has operated the pipeline systems with
regular and continuous maintenance, although the pipelines from Koch were only
recently acquired. Inspections and tests have been performed at prescribed
intervals in an effort to ensure the integrity of the systems.

     In two separate transactions, on July 1 and December 1, 1998, the
Partnership acquired approximately 4,200 miles of intrastate and interstate
common carrier pipelines in Texas, Oklahoma, Kansas, Nebraska, Colorado,
Louisiana, California, Montana, North Dakota, and South Dakota from Koch
Pipeline Company, L.P. Storage associated with the pipeline systems totals
approximately 3.5 million barrels. In addition, EOTT acquired a gas processing
plant referred to as Plant 8, with 20 million cubic feet per day of gas
processing capacity; a fractionation plant with 8,000 bpd of fractionation
capacity; 5 million gallons of refrigerated propane storage and related
distribution facilities.

     EOTT operates six active barge facilities in Louisiana, and one in Alabama.
Approximately 2.2 million barrels of storage capacity are associated with these
barge facilities. EOTT owns three terminal facilities for the storage and
terminalling of bulk petroleum products in Ohio, which are currently held for
sale, and one refined products terminal in Alabama. Approximately 431,000
barrels of storage capacity are associated with these bulk petroleum product
facilities.

ITEM 3. LEGAL PROCEEDINGS

     EOTT is, in the ordinary course of business, a defendant in various
lawsuits, some of which are covered in whole or in part by insurance. Although
no assurance can be given, the General Partner believes that the ultimate
resolution of litigation, individually and in the aggregate, will not have a
materially adverse impact on the Partnership's financial position or results of
operations. Various legal actions have arisen in the ordinary course of
business, the significant of which are discussed below:

     Wyoming Refining Company Matter. EOTT had a possible loss exposure of
approximately $1.47 million as a result of a dispute between Wyoming Refining
Company ("WRC") and the U.S. Minerals Management Service ("MMS"). MMS was
claiming that it was underpaid by WRC for certain Montana crude oil which was
delivered to WRC over a several-year period prior to 1993. On December 14, 1998,
EOTT received a letter from WRC stating that the MMS had withdrawn its claim and
no price adjustments would be necessary.

     State of Texas Royalty Suit. EOTT was served on November 9, 1995 with a
petition styled The State of Texas, et al. vs. Amerada Hess Corporation, et al.
The matter was filed in District Court in Lee County, Texas and involves several
major and independent oil companies and marketers as defendants. The plaintiffs
are attempting to put together a class action lawsuit alleging that the
defendants acted in concert to buy oil owned by members of the plaintiff class
in Lee County, Texas, and elsewhere in Texas, at "posted" prices, which the
plaintiffs allege were lower than true market prices. There is not sufficient
information in the petition to fully quantify the allegations set forth in the
petition, but the General Partner believes that any such claims against the
Partnership will prove to be without merit.

     The State of Texas, et al. vs. Amerada Hess Corporation, et al., Cause No.
97-12040; In the 53rd Judicial District Court of Travis County, Texas. This case
was filed on October 23, 1997 in Austin by the Texas Attorney General's office
and involves several major and independent oil companies and marketers as
defendants. EOTT was served on November 18, 1997. The petition states that the
State of Texas brought this action in its sovereign capacity to collect
statutory penalties recoverable under the Texas Common Purchaser Act, arising
from Defendants' alleged willful breach of statutory duties owed to royalty,
overriding royalty and working interest owners of crude oil sold to Defendants,
as well as alleged breach of Defendants' common law and contractual duties. The
Plaintiffs also allege that the Defendants have engaged in discriminatory
pricing of crude oil. This case appears to be similar to the Lee County, Texas
case filed by the State of Texas on November 9, 1995 and disclosed previously.
EOTT and several of the defendants have engaged in settlement negotiations with
the State of Texas, which, if consummated, would result in a dismissal of the
claims of the State.

     McMahon Foundation and J. Tom Poyner vs. Amerada Hess Corporation, et al.
(Including EOTT Energy Operating Limited Partnership), Civil Action No.
H-96-1155; United States District Court, Southern District of Texas, Houston
Division (Texas Federal Anti-Trust Suit). This suit was filed on April 10, 1996
as a class action complaint for violation of the federal antitrust laws and
involves several major and independent oil companies and marketers as
defendants. The relevant area is the entire continental United States, except
for Alaska, New York, Ohio, Pennsylvania, West Virginia and the Wilmington Field
at Long Beach, California. The plaintiffs claim that there is a combination and
conspiracy among the defendant oil companies to fix, depress, stabilize and
maintain at artificially low levels the price paid for the first purchase of
lease production oil sold from leases in which the class members own interests.
This was allegedly accomplished by agreement of the defendants to routinely pay
for first purchases at posted prices rather than competitive market prices and
maintain them in a range below competitive market prices through an undisclosed
scheme of using posted prices in buy/sell transactions among themselves to
create the illusion that posted prices are genuine market prices. The 



                                       13
<PAGE>   14

plaintiffs allege violations from October of 1986 forward. No money amounts were
claimed, and it is not possible to determine any potential exposure until
further discovery is done.

     Randolph Energy, Inc., et al. vs. Amerada Hess Corporation, et al., Civil
Action No. 2:97CV273PG; In the United States District Court for the Southern
District of Mississippi, Jackson Division (Mississippi Federal Anti-Trust Suit).
EOTT received the summons in this matter on August 18, 1997. The case was filed
on August 5, 1997 and is a class action complaint for alleged violation of the
federal antitrust laws which involves several major and independent oil
companies and marketers as defendants. The plaintiffs claim that this litigation
arises out of a combination and conspiracy of the defendant oil companies to
fix, depress, stabilize and maintain at artificially low levels the prices paid
for the first purchase of lease production oil sold from leases in which the
class members own interests. The issues appear to be a duplication of the issues
in the Texas Federal Anti-Trust Suit previously discussed. No money amounts were
claimed, and it is not possible to determine any potential exposure until
further discovery is done.

     Cameron Parish School Board, et al. vs. Texaco, Inc., et al.; Civil Action
No. C-98-111; In the United States District Court for the Western District of
Louisiana, Lake Charles Division (Louisiana Federal Anti-Trust Suit). This case
was originally filed as a state law claim in Louisiana. When the case was
removed to federal court, the anti-trust claims were added, similar to the
claims made in the Texas Federal Anti-Trust Suit and the Mississippi Federal
Anti-Trust Suit. The plaintiffs claim that this litigation arises out of a
combination and conspiracy of the defendant oil companies to fix, depress,
stabilize and maintain at artificially low levels the prices paid for the first
purchase of lease production oil sold from leases in which the class members own
interests. The issues appear to be a duplication of the issues in the Texas
Federal Anti-Trust Suit and the Mississippi Federal Anti-Trust Suit, both
previously discussed. On October 22, 1998, the judge granted the Plaintiffs'
motion to amend the petition and add additional defendants. The Partnership and
the General Partner were added to the case as defendants at that time. No money
amounts were claimed and it is not possible to determine any potential exposure
until further discovery is done.

     The Texas Federal Anti-Trust Suit, the Mississippi Federal Anti-Trust Suit
and the Louisiana Anti-Trust Suit, along with several other suits to which EOTT
is not a party, were consolidated and transferred to the Southern District of
Texas by Transfer Order dated January 14, 1998. The Judicial Panel on
Multidistrict Litigation made this recommendation due to similarity of issues in
the cases. EOTT and the General Partner, along with a number of other
defendants, have entered into a class-wide settlement with the defendants which
has been preliminarily approved by the Court. A final approval hearing on the
class-wide settlement is scheduled for April 5, 1999.

     Mobil Oil Corporation vs. EOTT Energy Operating Limited Partnership and
EOTT Energy Corporation, Cause No. CV98-04881, M-298th Judicial District Court,
Dallas County, Texas (Mobil Suit). This suit was filed on June 25, 1998 against
both EOTT and the General Partner. Mobil alleged that it overpaid EOTT in
connection with a crude oil contract between the parties. EOTT claimed that it
was entitled to offsets to the overpayment alleged by Mobil and tendered the
amount EOTT believed it owed. The case was settled in November of 1998, with
EOTT tendering cash and services to resolve the matter.

     Assessment for Crude Oil Production Tax from the Comptroller of Public
Accounts, State of Texas. The Partnership received a letter from the
Comptroller's Office dated October 9, 1998 assessing the Partnership for
severance taxes the Comptroller's Office alleges are due on a difference the
Comptroller's Office believes exists between the market value of crude oil and
the value reported on the Partnership's crude oil tax report for the period of
September 1, 1994 through December 31, 1997. The letter states that the action,
based on a desk audit of the Partnership's crude oil production reports, is
partly to preserve the statute of limitations where crude oil severance tax may
not have been paid on the true market price of the crude oil. The letter further
states that the 



                                       14
<PAGE>   15

Comptroller's position is similar to claims made in several lawsuits, including
the Texas Federal Anti-Trust Suit, in which the Partnership is a defendant. The
amount of the assessment, including penalty and interest, is approximately $1.1
million. While the claim is still being reviewed, the General Partner believes
the Partnership should be without liability in this matter.

     The Partnership believes that it has obtained or has applied for all of the
necessary permits required by federal, state, and local environmental agencies
for the operation of its business. Further, the Partnership believes that there
are no outstanding liabilities or claims relating to environmental matters
individually and in the aggregate, which would have a material adverse impact on
the Partnership's financial position or results of operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were no matters submitted to a vote of security holders during the
fourth quarter of 1998.

- ----------
     Distributions are shown in the quarter paid to Common Unitholders


     As of February 15, 1999, there were approximately 396 record holders of the
Partnership's Common Units, and there were an estimated 8,700 beneficial owners
of the Common Units held in a street name. There is no established public
trading market for the Partnership's Subordinated Units. Generally, the
Partnership will distribute 100% of its Available Cash as defined in the
Partnership Agreement within 45 days after the end of each quarter to
Unitholders of record and to the General Partner. Available Cash consists
generally of all of the cash receipts of the Partnership adjusted for its cash
distributions and net changes to reserves. The full definition of Available Cash
is set forth in the Partnership Agreement and amendments thereto, a form of
which is filed or has been filed previously as an exhibit hereto. Distributions
of Available Cash to the Subordinated Unitholders will be subject to the prior
rights of the Common and Special Unitholders to receive the Minimum Quarterly
Distribution of $0.475 per Unit ("MQD") for each quarter during the
Subordination Period and to receive any arrearages in the distribution of the

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


INFORMATION REGARDING FORWARD-LOOKING INFORMATION

     The statements in this Annual Report on Form 10-K that are not historical
information are forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. Such forward-looking statements include the discussions in "Management's
Discussion and Analysis of Financial Condition and Results of Operations." Any
forward-looking statements are not guarantees of future performance, involve
significant risks and uncertainties and actual results may vary materially from
those in the forward-looking statements as a result of various factors. See Item
1. Business - Information Regarding Forward-Looking Information for statements
regarding important factors that could cause actual results to differ materially
from those in the forward-looking statements herein. Although the Partnership
believes that its expectations regarding future events are based on reasonable
assumptions, it can give no assurance that these are all the factors that could
cause actual results to vary materially from the forward-looking statements or
that its expectations regarding future developments will prove to be correct.


OVERVIEW

     Through its affiliated limited partnerships, EOTT Energy Operating Limited
Partnership, EOTT Energy Canada Limited Partnership, and EOTT Energy Pipeline
Limited Partnership, EOTT is engaged in the purchasing, gathering, transporting,
trading, storage and resale of crude oil and other petroleum products and
related activities. Statement of Financial Accounting Standards No. 131,
"Reporting Disaggregated Information About a Business Enterprise", requires that
segment reporting for public companies be measured the same way management
identifies and evaluates information internally. EOTT adopted this standard for
year end 1998 reporting and restated all prior year information based on the
following reportable business segments: North American Crude Oil - East of
Rockies, Pipeline Operations and West Coast Operations (see Note 19 to the
Consolidated Financial Statements for certain financial information by business
segment). In late 1997, EOTT exited the East of Rockies refined products
business. See further discussion in the Note 5 to the Consolidated Financial
Statements.

     The purchase and resale of crude oil is a highly competitive activity with
very thin and volatile profit margins. EOTT's operating results are sensitive to
a number of factors including: grades or types of crude oil, individual refinery
demand for specific grades of crude oil, area market price structures for the
different grades of crude oil, location of customers, availability of
transportation facilities, and timing and costs (including storage) involved in
delivering crude oil to the appropriate customer. EOTT purchases crude oil lease
barrels at prevailing market prices. Generally, as EOTT purchases lease barrels,
it simultaneously enters into a corresponding sale transaction to secure a
profit, thereby minimizing or eliminating exposure to price fluctuations. In
addition, EOTT's marketing strategies also provide the potential to enhance the
value of the crude oil that EOTT purchases.


RECENT DEVELOPMENTS

     On December 1, 1998, the Partnership purchased certain crude oil gathering
and transportation assets in key oil producing regions from Koch. The
transaction almost tripled EOTT's pipeline mileage, almost doubled crude oil
lease barrels under contract and should strengthen profitability and cash flow.
The acquisition included approximately 3,900 miles of crude oil pipelines, crude
oil transport trucks, meter stations, vehicles, storage 



                                       18
<PAGE>   19

tanks and contracts for approximately 180,000 lease barrels of crude oil per day
from production in 11 central and western states including Texas, Oklahoma,
Kansas and California (the "Assets").

     The total purchase price was approximately $235.6 million and included
consideration given to Koch of $184.5 million in cash, 2,000,000 Common Units
and 2,000,000 Subordinated Units. EOTT financed the cash portion of the purchase
price through borrowings from Enron Corp. ("Enron"), the parent of EOTT Energy
Corp., the general partner of the Partnership, consisting of a $42 million
bridge loan due December 31, 1999, $135.7 million of term debt, due December 31,
1999, and $6.8 million from the Partnership's existing credit facility with
Enron. EOTT also increased its existing credit facility with Enron to $1 billion
in order to provide increased credit support for the Partnership because of its
increased size following the Koch acquisition.

     The Assets acquired from Koch, which complement EOTT's core crude oil
gathering and transportation business, should result in substantial economies of
scale and should strengthen EOTT's ability to serve customers throughout North
America. This substantial acquisition should enhance EOTT's ability to fund
Common Unit distributions from cash flow.

     Pursuant to a Support Agreement dated September 21, 1998, (a) Enron agreed
to make loans to the Partnership to fund the cash portion of the consideration
to be paid to Koch for the Assets at closing and to refinance indebtedness
incurred in a prior acquisition of assets from Koch on July 1, 1998, (b) Enron
agreed to increase and extend the Partnership's credit facility with Enron to $1
billion through December 31, 2001, (c) the Partnership agreed to issue 1,150,000
Special Units to Enron, (d) Enron agreed to contribute $21.9 million in
Additional Partnership Interests ("APIs") to the Partnership on the earlier of
the date certain proposals, discussed further below, are approved by the
Unitholders at a special meeting of Unitholders or May 17, 1999, (e) Enron
agreed that if certain proposals were approved by the Unitholders it would
extend its cash distribution support through the fourth quarter of 2001, and (f)
the Partnership agreed that, if any additional APIs were issued prior to
approval of certain proposals by the Unitholders, it would issue additional
Common Units at $19.00 per share in exchange for such additional APIs.

     On February 12, 1999, the Partnership obtained approval of proposals
presented at a Special Meeting of Unitholders. Approval of these proposals,
among other things, (a) authorized the Partnership to issue an additional 10
million Common Units to raise cash to reduce indebtedness, for acquisitions and
other Partnership purposes, (b) changed the terms of the Special Units so that
they became convertible into Common Units and (c) resulted in an increase in
Enron's cash distribution support to $29 million and an extension of that
support through the fourth quarter of 2001. As a result of the approval of the
proposals, Enron contributed the $21.9 million in APIs outstanding pursuant to
its commitment made in connection with the Support Agreement discussed in Note
12 to the Consolidated Financial Statements.

     The following review of the results of operations and financial condition
should be read in conjunction with the Consolidated Financial Statements and
Notes thereto. The results of operations for the twelve months ended December
31, 1998, 1997, and 1996 and the financial condition at December 31, 1998 and
1997 reflect the activities of EOTT Energy Partners, L.P. and its subsidiary
partnerships (the "Partnership"). Unless the context otherwise requires, the
term "EOTT" hereafter refers to the Partnership and its affiliated limited

     (1) Includes East of Rockies refined products business which was exited in
         1997.


     The North American Crude Oil - East of Rockies business segment and West
Coast Operations business segment are characterized by generally very thin and
volatile profit margins on purchase and sale transactions, and the absolute
price levels for crude oil and other petroleum products do not necessarily bear
a direct relationship to margins per barrel, although such price levels
significantly impact revenues and cost of sales. Gross margin is the difference
between the sales price of crude oil or other petroleum products and the cost of
crude oil and products purchased, including costs paid to third parties for
transportation and handling charges. As a result, period-to-period variations in
revenues and cost of sales are not meaningful, and therefore are not discussed
for the North American Crude Oil - East of Rockies and West Coast Operations
business segments. Pipeline Operations revenues are primarily a function of the
level of crude oil transported through the pipeline, known as throughput, and
the applicable pipeline tariffs.

TWELVE MONTHS ENDED DECEMBER 31, 1998 COMPARED WITH TWELVE MONTHS ENDED DECEMBER
31, 1997

     North American Crude Oil - East of Rockies. Operating income for the North
American Crude Oil - East of Rockies segment was $28.0 million in 1998 compared
to $19.5 million in 1997. Gross margin increased $9.4 million to $92.0 million
due primarily to renegotiations of uneconomic lease contracts during 1997 and
improved crude grade and basis differentials in 1998. East of Rockies crude oil
lease purchases were up slightly from an annual average of 282,400 bpd for 1997
to an annual average of 285,600 bpd in 1998. Operating expenses of $64.0 million
for 1998 were $0.9 million higher than 1997 due primarily to increased
depreciation and amortization related to the acquisitions of assets from Koch
partially offset by a reduction in employee related costs.


                                       20
<PAGE>   21

     Pipeline Operations. Pipeline Operations had operating income of $4.3 
million in 1998 compared to $1.8 million in 1997. Revenues increased $12.1
million to $31.5 million due primarily to increased activity related to the
acquisition of pipelines from Koch. Pipeline delivered volumes were 185,300 bpd
in 1998 compared to 142,000 bpd in 1997. Operating expenses of $26.6 million in
1998 were $8.9 million higher than 1997 due primarily to increased benefits and
employee related costs, increased operating costs and incremental depreciation
and amortization associated with the acquisition of pipelines from Koch.

     West Coast Operations. West Coast Operations had operating income of $0.2
million in 1998 compared to $0.1 million in 1997. Gross margin increased $0.4
million to $9.7 million due primarily to the acquisition of crude oil gathering
and natural gas liquid assets from Koch partially offset by a lower of cost or
market adjustment of certain propane inventories. Operating expenses of $9.5
million in 1998 were $0.3 million higher than 1997 due primarily to higher
benefits and other employee related costs partially offset by reduced operating
costs.

     Corporate and Other. Corporate and other costs of $25.3 million for 1998
were $3.7 million lower compared to 1997 due primarily to a non-recurring $6.5
million non-cash impairment associated with the termination of an information
system development project and $1.5 million impairment of three Ohio products
terminals held for sale due to the exit of the East of Rockies refined products
business in 1997 partially offset by increased legal expenses, system operating
costs, casualty and liability insurance costs, a non-recurring write-off of
certain information system development costs and severance payments made to a
former officer of the General Partner. Interest and related charges for 1998
were $10.2 million compared to $6.7 million in 1997. The increase is due
primarily to higher average short-term debt required to meet working capital
needs, primarily related to higher average crude inventories during 1998 and
debt used to finance the acquisition of assets from Koch in the third and fourth
quarters of 1998. Other income (expense), net, consisting primarily of gains
(losses) on transactions denominated in foreign currency; gains (losses) on the
sale of property, plant and equipment; and litigation settlements decreased $1.0
million to a loss of $1.8 million in 1998 due to an increase in litigation
settlements in 1998.

TWELVE MONTHS ENDED DECEMBER 31, 1997 COMPARED WITH TWELVE MONTHS ENDED DECEMBER
31, 1996.

     North American Crude Oil - East of Rockies. Operating income for the North
American Crude Oil - East of Rockies segment was $19.5 million in 1997 compared
to $47.1 million in 1996. Gross margin decreased $34.6 million to $82.6 million
due primarily to the deterioration in grade and basis differentials in 1997 and
1996 had unusually favorable crude oil market conditions. East of Rockies crude
lease purchases were up slightly from an annual average of 278,600 bpd for 1996
to an annual average of 282,400 bpd in 1997. Operating expenses of $63.1 million
for 1997 were $7.0 million lower than 1996 due to lower benefits and other
employee related costs, partially offset by severance costs associated with the
realignment initiatives discussed in the Notes to Consolidated Financial
Statements.

     Pipeline Operations. Pipeline Operations had operating income of 
$1.8 million in 1997 and in 1996. Revenues increased $5.1 million to $19.4
million due primarily to increased activity related to the acquisition of
pipeline and related assets from CITGO Pipeline Company. Pipeline delivered
volumes were 142,000 bpd in 1997 compared to 103,800 bpd in 1996. Operating
expenses of $17.7 million in 1997 were $5.6 million higher than 1996 due
primarily to increased operating costs and incremental depreciation and
amortization associated with the acquisition of pipeline and related assets from
CITGO Pipeline Company.

     West Coast Operations. West Coast Operations had operating income of $0.1
million in 1997 compared to $6.8 million in 1996. Gross margin decreased $6.2
million to $9.3 million due primarily to unusually favorable 


                                       21
<PAGE>   22

market conditions in 1996. Operating expenses of $9.2 million in 1997 were $0.5
million higher than 1996 due primarily to higher operating costs partially
offset by lower benefits and other employee related costs.

     Corporate and Other. Corporate and other costs of $29.0 million for 1997
were $5.2 million higher compared to 1996 due primarily to a $6.5 million
non-cash impairment associated with the termination of an information system
development project and a $1.5 million impairment of three Ohio terminals held
for sale due to the exit of the East of Rockies refined products business in
1997 partially offset by lower benefits and other employee related costs, lower
liability and casualty insurance costs, lower systems operating costs and
severance charges associated with the realignment initiatives and the exiting of
the East of Rockies refined products business discussed further in the Notes to
the Consolidated Financial Statements. Interest and related charges for 1997
were $6.7 million compared to $3.7 million in 1996. The increase is due
primarily to higher average short-term debt required to meet working capital
needs, primarily related to higher crude inventories and debt used to finance
the acquisition of crude oil pipeline assets from CITGO Pipeline Company in the
first quarter of 1997. Other income (expense), net, consisting primarily of
gains (losses) on transactions denominated in foreign currency; gains (losses)
on the sale of property, plant and equipment; and litigation settlements
decreased $0.9 million to a loss of $0.8 million in 1997 due primarily to losses
on foreign currency transactions.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows From Operating Activities

     Net cash provided by operating activities totaled $18.6 million in 1998
compared to net cash from operating activities being at breakeven in 1997. The
increase in operating cash flow is primarily due to an increase in gross margin
resulting from improved crude oil grade and basis differentials and the
renegotiation of uneconomic lease contracts during 1997 in the North American
Crude Oil - East of Rockies crude oil gathering business.

Cash Flows From Investing Activities

     Net cash used in investing activities totaled $224.7 million in 1998
compared to $21.5 million in 1997, primarily due to the asset acquisitions from
Koch. Cash additions to property, plant, and equipment of $232.9 million in 1998
primarily include $224.4 million representing cash consideration for the asset
acquisitions from Koch, $2.7 million for pipeline connections and improvements,
and $2.4 million for computer hardware.

     The General Partner estimates that capital expenditures necessary to
maintain the existing asset base at current operating levels will be
approximately $8 - $9 million each year. The level of capital expenditures by
the Partnership will vary depending upon prevailing energy markets, general
economic conditions and the current regulatory environment.

     The Partnership generally expects to fund short-term liquidity as well as
sustaining capital expenditures primarily from operating activities in addition
to lines of credit provided by Enron, more fully described in Note 7 to the
Consolidated Financial Statements. The Partnership may also issue additional
limited partner interests, the proceeds from which could be used to reduce
indebtedness, provide additional funds for acquisitions or other Partnership
needs.

Cash Flows From Financing Activities

     Net cash provided by financing activities totaled $205.4 million in 1998
compared to $20.0 million in 1997. The 1998 amount primarily represents
short-term borrowings to fund working capital needs and borrowings from Enron to
finance the asset acquisitions from Koch, reduced by distributions paid to
Unitholders of record for the period October 1, 1997 through September 30, 1998.


                                       22
<PAGE>   23

     During the first half of 1996, EOTT issued approximately 1.8 million Common
Units in exchange for $29.8 million in a private placement with Enron and
received $24.2 million for a promissory note issued to Enron. On July 16, 1996,
Enron and EOTT exchanged the Common Units for Special Units, more fully
described in Note 12 to the Consolidated Financial Statements.

     Cash distributions paid to Unitholders were $22.8 million and $29.7 million
for 1998 and 1997, respectively. In 1995, the Partnership issued Additional
Partnership Interests ("APIs") to Enron in exchange for $9.1 million in support
of the distributions paid to the General Partner and Common Unitholders during
the second and third quarters of 1995. Due to the losses incurred during 1997,
the third quarter distribution to all Common and Special Unitholders was paid
utilizing $2.0 million from the Partnership's Available Cash and the Partnership
issued APIs in exchange for $3.7 million in cash support from Enron. The 1997
fourth quarter distribution was paid in February 1998 using $1.9 million of
Available Cash from the Partnership and the issuance of APIs in exchange for
$3.8 million in cash support from Enron. The 1998 first and second quarter
distributions were paid using $6.1 million of Available Cash from the
Partnership and the issuance of APIs in exchange for $5.3 million in cash
support from Enron. Pursuant to the Support Agreement as discussed in Note 12 to
the Consolidated Financial Statements, all outstanding APIs were contributed to
the Partnership in February 1999.

Acquisition of Assets

     On February 1, 1997, the Partnership acquired over 400 miles of intrastate
and interstate common carrier pipelines in Louisiana and Texas from CITGO
Pipeline Company. Shipped volumes associated with these assets amount to
approximately 48,000 bpd from leases in certain regions of Arkansas, Louisiana
and Texas. Storage associated with the pipeline systems totals approximately 0.5
million barrels. The purchase price was approximately $12 million and was
financed with a note payable from Enron.

     On July 1, 1998, the Partnership acquired crude oil gathering and
transportation assets in West Texas and New Mexico from Koch. The asset purchase
included approximately 300 miles of common carrier pipelines, associated storage
facilities for approximately 500,000 barrels and lease purchase contracts for up
to 40,000 lease barrels of crude oil per day. The purchase price was
approximately $28.5 million and was financed with short-term borrowings from
Enron.

     As previously discussed in "Recent Developments," on December 1, 1998, the
Partnership acquired certain additional crude oil gathering and transportation
assets in key oil producing regions from Koch.

Working Capital and Credit Resources

     In 1995, Enron Corp. agreed to provide credit support (the "Credit
Facility") to the Partnership in the form of guarantees, letters of credit,
loans and letters of indemnity. The total amount of the credit support was $600
million, as amended December 19, 1996, had a maturity of March 31, 1999 and was
replaced with a new facility on December 1, 1998 as discussed below. As amended,
the agreement contained sublimits on the availability of the Credit Facility of
$100 million for working capital loans and $200 million for letters of credit.
Letter of credit fees were based on actual charges by the banks which range from
 .20% - .375% per annum. Interest on outstanding loans was charged at the London
Interbank Offering Rate ("LIBOR") plus 25 basis points per annum. At December
31, 1997, EOTT had a note payable of $39.3 million with Enron under a financing
arrangement for acquisitions and other capital projects (the "Note Payable").
This financing was provided at a rate of LIBOR plus 30 basis points per annum.
The maturity date of the Note Payable was March 31, 1999 and was redeemed and
reissued under the term loan discussed below.


                                       23
<PAGE>   24

     On December 1, 1998, Enron increased its existing credit facility with the
Partnership to provide additional credit support (the "Enron Facility") in the
form of guarantees, letters of credit and working capital loans through December
31, 2001. The total amount of the Enron Facility is $1.0 billion and contains
sublimits on the availability of the Enron Facility of $100 million for working
capital loans and $900 million for guarantees and letters of credit. Letter of
credit fees are based on actual charges by the banks which range from .20% -
 .375% per annum. Interest on outstanding loans is charged at LIBOR plus 250
basis points per annum.

     The Enron Facility is subject to defined borrowing base limitations
relating to the Partnership's activities and to the maintenance and protection
of the collateral. The Enron Facility permits distributions to Unitholders
subject to certain limitations based on the Partnership's earnings and other
factors. These covenants and restrictions are not expected to materially affect
EOTT's ability to operate the ongoing Partnership business.

     At December 31, 1998, EOTT had $175 million of debt (the "Term Loan")
outstanding with Enron under a financing arrangement to fund a portion of the
cash consideration paid to Koch for the assets purchased in 1998 and to
refinance indebtedness incurred in prior acquisitions. The Term Loan matures on
December 31, 1999. The interest rate on the Term Loan is LIBOR plus 300 basis
points.

     The Enron Facility and Term Loan are secured by a first priority lien on
and security interest in all receivables and inventory of the Partnership. The
borrowing base is the sum of cash and cash equivalents, specified percentages of
eligible receivables, inventory, and products contracted for or delivered but
not billed. The Enron Facility and Term Loan are non-recourse to the General
Partner and the General Partner's assets. The Partnership is restricted from
entering into additional financing arrangements without the prior approval of
Enron.

     In addition, at December 31, 1998, EOTT had $42.0 million of debt
outstanding with Enron under a $100 million bridge loan (the "Bridge Loan") to
finance a portion of the cash consideration for the acquisition of assets from
Koch. The interest rate on the Bridge Loan is initially LIBOR plus 400 basis
points. At the end of each three-month period, the spread on the Bridge Loan
will increase by 25 basis points. The Bridge Loan is unsecured and matures on
December 31, 1999.

     As discussed above, the interim Bridge Loan ($42 million) and Term Loan
($175 million) provided by Enron are due December 31, 1999. The General Partner
intends to refinance the Bridge Loan and Term Loan on a long-term basis before
maturity. The General Partner anticipates that the debt will be refinanced using
a combination of financing alternatives including (a) third party bank debt,
(b) private placement of debt, (c) an offering of high yield debt and/or (d) an
equity offering utilizing some portion of the additional 10 million Common Units
which were authorized to be issued subsequent to year end (See Note 20).

      At December 31, 1998, EOTT had $44.4 million in letters of credit and
$28.3 million in loans outstanding under the Enron Facility at an average annual
interest rate of approximately 6.1%. The amount outstanding at December 31, 1998
under the Term Loan was $175.0 million with an average annual interest rate of
8.5% and under the Bridge Loan was $42.0 million with an average annual interest
rate of 9.5%. The actual interest rate may vary based on the length of the
borrowings. In addition, guarantees outstanding totaled $366.4 million of which
$290.9 million were used.

     At December 31, 1997, EOTT had $92.5 million in letters of credit and $70.0
million in loans outstanding under the Credit Facility at an average annual
interest rate of approximately 5.8%. The amount outstanding under the Note
Payable at December 31, 1997 was $39.3 million with an average annual interest
rate of 6.0%. The actual interest rate may vary based on the length of the
borrowings. In addition, guarantees outstanding totaled $402.5 million of which
$292.3 million were used.


                                       24
<PAGE>   25

     At December 31, 1997, EOTT was in technical violation of the negative
covenants relating to the Tangible Net Worth, Leverage Ratio and Working Capital
Ratio in the Credit Facility and Note Payable due principally to the operating
loss associated with the deterioration of grade and basis differentials in the
crude oil markets. EOTT received a waiver for these violations from Enron.

     The General Partner believes that the Enron Facility, Bridge Loan, Term
Loan and subsequent refinancing discussed previously will be sufficient to
support the Partnership's crude oil purchasing activities and working capital
and liquidity requirements. No assurance, however, can be given that the General
Partner will not be required to reduce or restrict the Partnership's gathering
and marketing activities because of limitations on its ability to obtain credit
support and financing for its working capital needs.

     The Partnership's ability to obtain letters of credit to support its
purchases of crude oil or other petroleum products is fundamental to the
Partnership's gathering and marketing activities. Additionally, EOTT has a
significant need for working capital due to the large dollar volume of marketing
transactions in which it engages. Any significant decrease in the Partnership's
financial strength, regardless of the reason for such decrease, may increase the
number of transactions requiring letters of credit or other financial support,
make it more difficult for the Partnership to obtain such letters of credit,
and/or increase the cost of obtaining them. This could in turn adversely affect
the Partnership's ability to maintain or increase the level of its purchasing
and marketing activities or otherwise adversely affect the Partnership's
profitability and Available Cash as defined in EOTT's Partnership Agreement and
amendments thereto.

     Generally, the Partnership will distribute 100% of its Available Cash
within 45 days after the end of each quarter to Unitholders of record and to the
General Partner. Available Cash consists generally of all of the cash receipts
of the Partnership adjusted for its cash distributions and net changes to
reserves. The full definition of Available Cash is set forth in the Partnership
Agreement and amendments thereto, a form of which is filed or has been
previously filed as an exhibit to this Annual Report on Form 10-K. Distributions
of Available Cash to the Subordinated Unitholders are subject to the prior
rights of the Common and Special Unitholders to receive the Minimum Quarterly
Distribution ("MQD") for each quarter during the Subordination Period, and to
receive any arrearages in the distribution of the MQD on the Common Units for
prior quarters during the Subordination Period.

     MQD is $0.475 per Unit. As discussed in Note 20 to the Consolidated
Financial Statements, Enron has committed to provide total cash distribution
support in an amount necessary to pay MQDs, with respect to quarters ending on
or before December 31, 2001, in an amount up to an aggregate of $29 million in
exchange for APIs. See further discussion in Note 12 to the Consolidated
Financial Statements regarding the contribution of $21.9 million in APIs
subsequent to year-end.

     Any APIs purchased by Enron are not entitled to cash distributions or
voting rights. Originally, the APIs were required to be redeemed if and to the
extent that Available Cash for any quarter exceeded an amount necessary to
distribute the MQD on all Common and Subordinated Units and to eliminate
arrearages, if any, in the MQD on Common Units for prior periods. In February
1997, the General Partner amended the Partnership Agreement to provide that a
holder of APIs may, at its option, waive its right to receive distributions of
Available Cash to which it would otherwise be entitled to and to provide that in
such case the Partnership may retain such cash for later distribution to
partners or for use in the Partnership's business in subsequent periods. The
Partnership's Available Cash for the fourth quarter of 1996 was substantially in
excess of the amount necessary to distribute the MQD on all outstanding Units,
and upon adoption of the amendment, Enron, the holder of APIs, waived its right
to receive such excess cash in redemption of APIs. The February 1997 amendments
to the Partnership Agreement also provided that after the end of the
Subordination Period a holder of Subordinated Units may convert such Units into
Common Units either in whole or in part from time to time. The amendments also
provided that any unconverted Units will be renamed "Class B Units" after the
end of the 



                                       25
<PAGE>   26

Subordination Period. Prior to the amendments, the Partnership Agreement
provided that conversion would occur only on an all or none basis. See Part II,
Item 5, "Market for Registrant's Common Units and Related Security Holder
Matters."

     The Partnership Agreement authorizes EOTT to cause the Partnership to issue
additional limited partner interests, the proceeds from which could be used to
reduce indebtedness, provide additional funds for acquisitions or other
Partnership needs.

     At December 31, 1998, EOTT has outstanding forward commodity repurchase
agreements of approximately $83.0 million. Pursuant to the agreements, which had
terms of thirty days, EOTT repurchased the crude oil inventory on January 20,
1999 for approximately $83.4 million.

YEAR 2000

     The Year 2000 problem generally results from the use in computer hardware
and software of two digits rather than four digits to define the applicable
year. When computer systems must process dates both before and after January 1,
2000, two-digit year "fields" may create processing ambiguities that can cause
errors and system failures. For example, computer programs that have
date-sensitive features may recognize a date represented by "00" as the year
1900, instead of 2000.

     The effects of the Year 2000 problem are exacerbated because of the
interdependence of computer and telecommunications systems in the United States
and throughout the world. This interdependence certainly is true for the
Partnership and its suppliers, trading partners, and customers.

State of Readiness

     The General Partner's Board of Directors has been briefed about the Year
2000 problem. The Board has adopted a Year 2000 plan (the "Plan") aimed at
taking reasonable steps to prevent the Partnership's mission-critical functions
from being impaired due to the Year 2000 problem. "Mission-critical" functions
are those critical functions whose loss would cause an immediate stoppage of or
significant impairment to the Partnership's business.


                                       26
<PAGE>   27

     The Partnership is implementing the Plan, which will be modified as events
warrant. Under the Plan, the Partnership will continue to inventory its
mission-critical computer hardware and software systems and embedded chips
(computer chips with date-related functions, contained in a wide variety of
devices), and software; assess the effects of Year 2000 problems on the
mission-critical functions of the Partnership's businesses; remedy material
disruptions or other material adverse effects on mission-critical functions,
processes and systems; verify and test the mission-critical systems to which
remediation efforts have been applied; and attempt to ameliorate those
mission-critical aspects of the Year 2000 problem that are not remediated by
January 1, 2000, including the development of contingency plans to cope with the
mission-critical consequences of Year 2000 problems that have not been
identified or remediated by that date.

     Implementation of the Plan is directly supervised by the General Partner's
Chief Information Officer, who is the Year 2000 Project Director. The Project
Director coordinates the implementation of the Plan with the assistance of an
Oversight Committee, consisting of selected employees of the General Partner and
one member of its Board of Directors. The Partnership also has engaged (or will
engage, as appropriate) certain outside consultants, technicians and other
external resources to aid in formulating and implementing the Plan.

     The Plan recognizes that the computer, telecommunications, and other
systems ("Outside Systems") of outside entities ("Outside Entities") have the
potential for major, mission-critical, adverse effects on the conduct of the
Partnership's business. The Partnership does not have control of these Outside
Entities or Outside Systems. However, the Plan includes an ongoing process of
contacting Outside Entities whose systems, in the General Partner's judgment,
have, or may have, a substantial effect on the Partnership's ability to continue
to conduct the mission-critical aspects of its business without disruption from
Year 2000 problems. The Plan envisions the Partnership attempting to inventory
and assess the extent to which these Outside Systems may not be "Year 2000
ready" or "Year 2000 compatible" (that is, able to process data reliably, both
before and after January 1, 2000, without disruption due to an inability
reliably to process date information). The Partnership will attempt reasonably
to coordinate with these Outside Entities in an ongoing effort to obtain
assurance that the Outside Systems that are mission-critical to the Partnership
will be Year 2000 compatible well before January 1, 2000. Consequently, the
Partnership will work prudently with Outside Entities in a reasonable attempt to
inventory, assess, analyze, convert (where necessary), test (where necessary),
and develop contingency plans for the Partnership's connections to these
mission-critical Outside Systems, to ascertain the extent to which they are, or
can be made to be, Year 2000 ready and compatible with the Partnership's
remediation of its own mission-critical systems.

     It is important to recognize that the processes of inventorying, assessing,
analyzing, converting (where necessary), testing (where necessary), and
developing contingency plans for mission-critical items in anticipation of the
Year 2000 event are necessarily iterative processes. That is, the steps are
repeated as the Partnership learns more about the Year 2000 problem and its
effects on the Partnership's internal systems and on Outside Systems. As the
steps are repeated, it is likely that new problems will be identified and
addressed. The Partnership anticipates that it will continue with these
processes through January 1, 2000 and, if necessary based on experience, into
the Year 2000 in order to assess and remediate problems that reasonably can be
identified only after the start of the new century.

     As of February 1999, the Partnership is at various stages in implementation
of the Plan as shown in the following tables. The Plan includes verification and
validation of certain of the Partnership's mission-critical facilities and
functions by independent consultants. These consultants will participate to
varying degrees in many or all of the stages, including the inventory,
assessment, and testing phases. The Partnership will continue closely to monitor
work under the Plan and will revise estimated completion dates for the initial
iteration of each listed process according to experience. The Koch acquisition
in December of 1998 has caused some of the dates set forth below to be adjusted.
All dates are only relevant for the initial iteration of the applicable stage of
the Plan. Any notation of "complete" conveys the fact only that the initial
iteration of this phase has been substantially completed.

Costs to Address Year 2000 Issues

     Preliminary estimates of the total Year 2000 costs, which will be expensed
as incurred, range from $2 million to $3 million. However, the estimated costs
of implementing the Plan do not take into account the costs, if any, that might
be incurred as a result of Year 2000 related failures that occur despite the
Partnership's implementation of the Plan. These projects, which began in 1997,
will continue through 1999. Although management believes that its estimates are
reasonable, there can be no assurance, for the reasons stated in the "Summary"
section, below, that the actual costs of implementing the Plan will not differ
materially from the estimated costs or that the Partnership will not be
materially adversely affected by Year 2000 issues.

Year 2000 Risk Factors

     Certain of the Partnership's operations are regulated by governmental
authorities. The Partnership expects to satisfy these regulatory authorities'
requirements for achieving Year 2000 readiness. If the Partnership's reasonable
expectations in this regard are in error, and if a regulatory authority should
order the temporary cessation of the Partnership's operations in one or more of
these areas, the adverse effect on the Partnership could be material. Outside
Entities could face similar problems that materially adversely affect the
Partnership.

     Between now and 2000 there will be increased competition for people skilled
in the technical and managerial skills necessary to deal with the Year 2000
problem. While the Partnership is taking substantial precautions to recruit and
retain sufficient people skilled in dealing with the Year 2000 problem, and has
hired consultants who bring additional skilled people to deal with the Year 2000
problem as it affects the Partnership, the Partnership could face shortages of
skilled personnel or other resources, such as Year 2000 ready computer chips,
and these shortages might delay or otherwise impair the Partnership's ability to
assure that its mission-critical systems are Year 2000 ready. Outside Entities
could face similar problems that materially adversely affect the Partnership.
The General Partner believes that the possible impact of the shortage of skilled
people is not, and will not be, unique to the Partnership.

     The Partnership estimates that its mission-critical systems will be Year
2000-ready substantially before January 1, 2000. However, there is no assurance
that the Plan will succeed in accomplishing its purpose or that 



                                       28
<PAGE>   29

unforeseen circumstances will not arise during the implementation of the Plan
that would materially adversely affect the Partnership.

     The Partnership is taking reasonable steps to identify, assess, and, where
appropriate, to replace devices that contain embedded chips. Despite these
reasonable efforts, the Partnership anticipates that it will not be able to find
and remediate all embedded chips in the Partnership's systems. Further, the
Partnership anticipates that Outside Entities on which the Partnership depends
also will not be able to find and remediate all embedded chips in their systems.
Some of the embedded chips that fail to operate or that produce anomalous
results may create system disruptions or failures. Some of these disruptions or
failures may spread from the systems in which they are located to other systems
in a cascade. These cascading failures may have adverse effects upon the
Partnership's ability to maintain safe operations, and may also have adverse
effects upon the Partnership's ability to serve its customers and otherwise to
fulfill certain contractual and other legal obligations. The embedded chip
problem is widely recognized as one of the more difficult aspects of the Year
2000 problem across industries and throughout the world. The possible adverse
impact of the embedded chip problem is not, and will not be, unique to the
Partnership.

     The Partnership cannot assure that suppliers upon which it depends for
essential goods and services will convert and test their mission-critical
systems and processes in a timely manner. Failure of delay by all or some of
these entities, including the U.S. and state or local governments and foreign
governments, could create substantial disruptions having a material adverse
affect on the Partnership's business.

     In a recent Securities and Exchange Commission release regarding Year 2000
disclosures, the Securities and Exchange Commission stated that public companies
must disclose the most reasonably likely worst case Year 2000 scenario. Analysis
of the most reasonably likely worst case Year 2000 scenarios the Partnership may
face leads to contemplation of the following possibilities: widespread failure
of electrical, gas, and similar supplies by utilities serving the Partnership;
widespread disruption of the services of communications common carriers; similar
disruption to means and modes of transportation for the Partnership and its
employees, contractors, suppliers, and customers; significant disruption to the
Partnership's ability to gain access to, and remain working in, office buildings
and other facilities; the failure of substantial numbers of the Partnership's
mission-critical information (computer) hardware and software systems, including
both internal business systems and systems (such as those with embedded chips)
controlling operational facilities such as electrical generation, transmission,
and distribution systems and oil facilities and pipelines; and the failure of
Outside Systems, the effects of which would have a cumulative material adverse
impact on the Partnership's mission-critical systems. Among other things, the
Partnership could face substantial claims by customers or loss of revenues due
to service interruptions, inability to fulfill contractual obligations,
inability to account for certain revenues or obligations or to bill customers
accurately and on a timely basis, and increased expenses associated with
litigation, stabilization of operations following mission-critical failures, and
the execution of contingency plans. The Partnership could also experience an
inability by customers, traders, and others to pay, on a timely basis or at all,
obligations owed to the Partnership. Under these circumstances, the adverse
effect on the Partnership, and the diminution of the Partnership's revenues,
would be material, although not quantifiable at this time. Further in this
scenario, the cumulative effect of these failures could have a substantial
adverse effect on the economy, domestically and internationally. The adverse
effect on the Partnership, and the diminution of the Partnership's revenues,
from a domestic or global recession or depression, also is likely to be
material, although not quantifiable at this time.

     The Partnership will continue to monitor business conditions with the aim
of assessing and quantifying material adverse effects, if any, that result or
may result from the Year 2000 problem.

Contingency Plans

     As part of the Plan, the Partnership is developing contingency plans that
will deal with two aspects of the Year 2000 problem: (1) that the Partnership,
despite its good-faith, reasonable efforts, may not have satisfactorily
remediated all its internal mission-critical systems; and (2) that Outside
Systems may not be Year 2000 ready, despite the Partnership's good-faith,
reasonable efforts to work with Outside Entities. The Partnership's contingency
plans are being designed to minimize the disruptions or other adverse effects
resulting from Year 2000 incompatibilities regarding these mission-critical
functions or systems, and to facilitate the early identification and remediation
of mission-critical Year 2000 problems that first manifest themselves after
January 1, 2000.

     These contingency plans will contemplate an assessment of all its
mission-critical internal information technology systems and its internal
operational systems that use computer-based controls. This process has begun and
will continue as circumstances require. Further, the Partnership will in that
time frame assess any mission-critical disruptions due to Year 2000-related
failures that are external to the Partnership. These assessments will be
conducted for all of the Partnership's operations.

     These contingency plans include, where appropriate, the creation of teams
that will be standing by on the eve of the new millennium, prepared to respond
rapidly and otherwise as necessary to mission-critical Year 2000-related
problems as soon as they become known. The composition of teams that are
assigned to deal with Year 2000 problems will vary according to the nature,
mission-criticality, and location of the problem.

Summary

     The Partnership has a Plan to deal with the Year 2000 challenge and
believes that it will be able to achieve substantial Year 2000 readiness with
respect to the mission-critical systems that it controls. From a forward-looking
perspective, the extent and magnitude of the Year 2000 problem as it will affect
the Partnership, both before and for some period after January 1, 2000, are
difficult to predict or quantify for a number of reasons. Among these are: the
difficulty of locating "embedded" chips that may be in a great variety of
mission-critical hardware used for process or flow control, environmental,
transportation, access, communications, and other systems; the difficulty of
inventorying, assessing, remediating, verifying and testing Outside Systems; the
difficulty in locating all mission-critical software (computer code) internal to
the Partnership that is not Year 2000 compatible; and the unavailability of
certain necessary internal or external resources, including but not limited to
trained technicians and other personnel to perform adequate remediation,
verification, and testing of mission-critical Partnership systems or Outside
Systems. There can be no assurance, for example, that all of the Partnership's
systems and all Outside Systems will be adequately remediated so that they are
Year 2000 ready by January 1, 2000, or by some earlier date, so as not to create
a material disruption to the Partnership's business. If, despite the
Partnership's reasonable efforts under its Year 2000 Plan, there are
mission-critical Year 2000-related failures that create substantial disruptions
to the Partnership's business, the adverse impact on the Partnership's business
could be material. Year 2000 costs are difficult to estimate accurately because
of unanticipated vendor delays, technical difficulties, the impact of tests of
Outside Systems, and similar events. Moreover, the estimated costs of
implementing the Plan do not take into account the costs, if any, that might be
incurred as a result of Year 2000-related failures that occur despite the
Partnership's implementation of the Plan.

OTHER MATTERS

Recent Accounting Pronouncements

     Statement of Financial Accounting Standards ("SFAS") No. 130,
"Comprehensive Income" requires the presentation of comprehensive income which
is traditional net income (loss) adjusted for certain items that 


                                       30
<PAGE>   31

previously were only reflected as direct charges or credits to equity. EOTT
adopted SFAS No. 130 in the first quarter of 1998. For the years ended December
31, 1998, 1997 and 1996 traditional net income (loss) and comprehensive net
income (loss) are the same.

     SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
Information" requires that segment reporting for public companies be measured
the same way management identifies and evaluates information internally. EOTT
adopted SFAS No. 131 for year end 1998 reporting and restated prior year
information based on the following reportable business segments - North American
Crude Oil - East of Rockies, Pipeline Operations and West Coast Operations. See
Note 19 to the Consolidated Financial Statements.

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use", which establishes new
accounting and reporting standards for the costs of computer software developed
or obtained for internal use. The statement requires companies to capitalize
certain costs that are incurred in developing or designing computer software.
This statement is effective for financial statements beginning after December
15, 1998. The impact of this new standard will not have a significant effect on
EOTT's financial position or results of operations.

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". The Statement
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. The Statement requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting. SFAS No. 133 is effective for fiscal years beginning after
June 15, 1999. The standard cannot be applied retroactively but early adoption
is permitted. EOTT has not yet determined the impact of adopting SFAS No. 133;
however, this standard could increase volatility in earnings and partners'
capital, through other comprehensive income.

     In December 1998, the Emerging Issues Task Force ("EITF") reached a
consensus on Issue 98-10, "Accounting for Contracts Involved in Energy Trading
and Risk Management Activities." The Issue 98-10 is effective for fiscal years
beginning after December 15, 1998, and requires energy trading contracts (as
defined) to be recorded at fair value on the balance sheet, with the change in
fair value included in earnings. The consensus requires the effect of initial
application of Issue 98-10 to be recorded as a cumulative effect of a change in
accounting principle effective January 1, 1999, for calendar year companies.
Management has determined that the cumulative effect of the adoption of the new
accounting standard will be an increase in net income which will not be in
excess of $2.0 million.

OUTLOOK

     Management expects onshore North American crude oil production to continue
to decline annually. EOTT plans to continue aggressively pursuing strategies
that management anticipates would result in increased market share of domestic
lease barrel production. By offering an attractive combination of integrated
producer support, such as field level service and division order services, EOTT
plans to increase its producer base by maintaining its reputation for
high-quality, responsive customer service. By leveraging and enhancing its
multi-region presence, EOTT plans to increase marketing and trading
opportunities both domestically and in Canada.


                                       31
<PAGE>   32

     EOTT engages and will continue to engage in futures and over-the-counter
transactions principally for the purpose of hedging or enhancing the value of
the Partnership's physical business. Management believes that the hedging
program is effective and does not have a material adverse impact on the
Partnership's results of operations.

     The asset acquisitions from Koch are a major step forward for EOTT. The new
assets, which complement EOTT's core crude oil business, should result in
substantial economies of scale and should strengthen EOTT's ability to serve
customers throughout North America. In addition, these acquisitions should
enhance EOTT's ability to fund Common Unit distributions from cash flows.

     EOTT will continue to pursue attractive acquisition or business combination
opportunities to increase its scale of business, add cash flow, and reduce
earnings volatility. Acquisitions that result in increased lease purchase
volumes should help to enhance EOTT's marketing and trading opportunities. EOTT
management is committed to continue improving internal business processes in all
operational, marketing, and administrative areas and thereby achieve
improvements in productivity.

     Historically, this business has been very competitive with thin and
volatile profit margins. Due to the volatility of crude oil prices and the
decline in crude oil production, crude oil gathering margins continue to suffer
industry wide. Although there was improvement in crude margins in 1998, margins
have not returned to historical levels. The volatility of the market and the
amount of crude oil produced cannot be projected with any level of certainty.
The Partnership intends to continue to pay MQDs to all its Common and Special
Unitholders; however, due to the volatility of the market and the decline in
crude oil being produced which affects operating results, it is possible that
distribution support from Enron may be needed to pay MQDs for the first quarter
of 1999 and for other quarters in the future. Enron has committed to provide
total cash distribution support in an amount necessary to pay MQDs and has
increased its cash distribution support to $29 million and extended it through
the fourth quarter of 2001, which will further assure Common and Special
Unitholders of continued reliable distributions.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     EOTT enters into forwards, futures and other contracts primarily for the
purpose of hedging the impact of market fluctuations on assets, liabilities or
other contractual commitments. The use of financial instruments may expose EOTT
to market and credit risks resulting from adverse changes in commodity prices,
interest rates and foreign exchange rates. The major market risks are discussed
below:

     Commodity Price Risk. Commodity price risk is a consequence of gathering
crude oil at the lease and marketing the crude oil to refineries or other trade
partners. EOTT uses forwards, futures, swaps and options to mitigate price
exposure and manages this risk on a portfolio basis.

     Interest Rate Risk. Interest rate risk is the result of having variable
rate debt obligations, as changing interest rates impact the discounted value of
future cash flows.

     Foreign Currency Exchange Rate Risk. Foreign currency exchange rate risk is
the result of EOTT's Canadian operations. The primary purpose of EOTT's foreign
currency hedging activities is to protect against the volatility associated with
foreign currency purchase and sale transactions.


                                       32
<PAGE>   33

COMMODITY PRICE AND FOREIGN CURRENCY RISK

     EOTT has performed a value at risk analysis of virtually all of its
financial assets and liabilities. Value at risk incorporates numerous variables
that could impact the fair value of EOTT's investments, including commodity
prices and foreign exchange rates, as well as correlation within and across
these variables. EOTT's methodology includes the use of delta/gamma
approximations for option positions and relies to a certain extent on historical
correlations across commodity groups. EOTT estimates value at risk commodity and
foreign exchange exposures using a model based on Monte Carlo simulation of
delta/gamma positions which captures a significant portion of the exposure
related to option positions. Both value at risk methods utilize a one-day
holding period and a 95% confidence level. Cross-commodity correlations are used
as appropriate.

     The use of value at risk models allows management to aggregate risks across
the Partnership, compare risk on a consistent basis and identify the drivers of
risk. Because of the inherent limitations to value at risk, including the use of
delta/gamma approximations to value options, subjectivity in the choice of
liquidation period and reliance on historical data to calibrate the models, EOTT
relies on value at risk as only one component in its risk control process.

     The following table illustrates the value at risk for commodity price and
foreign currency risk (in millions):

     (1) The above value at risk amount represents derivative commodity
         instruments, primarily commodity futures contracts, entered into to
         hedge future physical crude oil purchase commitments. These commitments
         to purchase physical crude oil have not been included in the above
         value at risk computation.

     (1) Amounts approximate fair value because of their market-based interest 
         rate.

     (2) The Enron Facility has a maturity of December 2001. However, the
         borrowings under the Enron Facility are for working capital and are 
         classified as a short-term obligation. If the borrowings were held to 
         maturity, the average interest rates would be LIBOR plus 250 basis 
         points.

The committee has the authority to review, at the request of General Partner,
specific matters as to which the General Partner believes there may be a
conflict of interest in order to determine if the resolution of such conflict is
fair and reasonable to the Partnership. In addition, the committee has the
authority and responsibility for selecting the Partnership's independent public
accountants, reviewing the Partnership's annual audit and resolving accounting
policy questions.

DIRECTORS AND EXECUTIVE OFFICERS OF THE GENERAL PARTNER

     Set forth below is certain information concerning the directors and
executive officers of the General Partner. All directors of the General Partner

(1)  The dollar amounts under these columns represent the potential realizable
     value of each grant of Enron Corp. stock options assuming that the market
     price of Common Stock appreciates in value from the date of grant at the 5%
     and 10% annual rates prescribed by the SEC and therefore are not intended
     to forecast possible future appreciation, if any, of the price of Common
     Stock.

     The dollar amounts under these columns represent the potential realizable
     value of each grant of EOTT Energy Corp. unit options assuming the
     Subordinated Unit option converts to a Common Unit option and the market
     price of a Common Unit appreciates in value from the date of grant at the
     5% and 10% annual rates prescribed by the SEC. The dollar amounts shown are
     not intended to forecast possible future appreciation, if any, of the price
     of Common Units.

(2)  Represents stock options awarded during 1998. Options have a five-year
     term, and were 25% vested on the date of grant with an additional 25%
     vesting each anniversary of the date of grant.

     Represents unit option grants under EOTT Energy Corp.'s Unit Option Plan.
     Grants are ten-year grants and become 20% vested on the first anniversary
     date of grant with an additional 20% vesting each anniversary of the date
     of grant.

(3)  An appreciation in stock price, which will benefit all stockholders, is
     required for optionees to receive any gain. A stock price appreciation of
     zero percent would render the option without value to the optionees.

(4)  Includes shares issued on December 31, 1998 under the All Employee Stock
     Option Program to employees hired during 1998.

(5)  Weighted average exercise price of all Enron stock options granted to
     employees in 1998.

(6)  Appreciation for All Employee and Director Optionees is calculated using
     the maximum allowable option term of ten years, even though in some cases
     the actual option term is less than ten years. Appreciation for all
     shareholders is calculated using an assumed ten-year option term, the
     weighted average exercise price for All Employee and Director Optionees
     ($49.9120) and the number of shares of Common Stock issued and outstanding
     on December 31.

(1)  The dollar value in this column for EOTT options was calculated by assuming
     the Subordinate Unit option converts to a Common Unit option and
     determining the difference between the fair market value of the Common
     Units and the exercise value of the option at the end of the fiscal year.
     The value of EOTT Energy Common Units at year-end 1998 was $15.75 and the
     Subordinated Unit grant price is $15.00.

(2)  The dollar value in this column for Enron options was calculated by
     determining the difference between the fair market value underlying the
     option as of December 31, 1998 ($57.0625) and the grant price.

LONG TERM INCENTIVE PLAN AWARDS IN 1998

     In October 1997, the Board of Directors adopted the EOTT Energy Corp. Long
Term Incentive Plan (Plan). The Plan is intended to provide key employees with
Phantom Appreciation Rights ("PAR"), which is a right to receive cash based on
the performance of the Partnership prior to the time the PAR is redeemed. The
Plan has a five year term beginning January 1, 1997 and PAR awards vest in 25%
increments over a four year period following the grant year. The following table
provides information concerning awards of PAR's under the Plan during 1998
pursuant to the Named Officers reflected in the Summary Compensation Table.

ENRON BENEFIT AND COMPENSATION PLANS

     EOTT Energy Corp. employees continue benefit accrual under the Enron Corp.
Cash Balance Plan. EOTT Energy Corp. employees continue to be eligible for
participation in the Enron Corp. Savings Plan.

RETIREMENT PLANS AND SUPPLEMENTAL BENEFIT PLANS

     Enron maintains the Enron Corp. Cash Balance Plan ("Cash Balance Plan")
which is a noncontributory defined benefit plan to provide retirement income for
employees of Enron and its subsidiaries. Through December 31, 1994, participants
in the Cash Balance Plan with five years or more of service were entitled to
retirement benefits in the form of an annuity based on a formula that uses a
percentage of final average pay and years of service. In 1995, Enron's Board of
Directors adopted an amendment to and restatement of the Cash Balance Plan
changing the plan's name from the Enron Corp. Retirement Plan to the Enron Corp.
Cash Balance Plan. In connection with a change to the retirement benefit
formula, all members became fully vested in retirement benefits earned through
December 31, 1994. The formula in place prior to January 1, 1995 was suspended
and replaced with a benefit accrual in the form of a cash balance of 5% of
annual base pay beginning January 1, 1996. Under the Cash Balance Plan, each
employee's accrued benefit will be credited with interest based on 10-year
Treasury Bond yields.


                                       39
<PAGE>   40

     Enron also maintains a noncontributory employee stock ownership plan
("ESOP") which covers all eligible employees. Allocations to individual
employees' retirement accounts within the ESOP offset a portion of benefits
earned under the Cash Balance Plan. December 31, 1993 was the final date on
which ESOP allocations were made to employees' retirement accounts.

     Directors who are not employees are not eligible to participate in the Cash
Balance Plan.

     In addition, Enron has a Supplemental Retirement Plan that is designed to
assure payments to certain employees of that retirement income that would be
provided under the Cash Balance Plan except for the dollar limitation on accrued
benefits imposed by the Internal Revenue Code of 1986, as amended.

     The following table sets forth the estimated annual benefits payable under
normal retirement at age 65, assuming current remuneration levels without any
salary projection, and participation until normal retirement at age 65, with
respect to the Named Officers under the provisions of the foregoing retirement
plans:

         Note: The estimated annual benefits payable are based on the straight

     Plan.

EOTT ENERGY CORP. SEVERANCE PLAN

     The EOTT Energy Corp. Severance Pay Plan as amended provides for the
payment of benefits to employees who are terminated for failing to meet
performance objectives or standards, or who are terminated due to reorganization
or economic factors. The amount of benefits payable for performance related
terminations is based on length of service and may not exceed six weeks' pay in
the event such employee signs a Waiver and Release of Claims Agreement. For
those terminated as the result of reorganization or economic circumstances, the
benefit is based on length of service with one week's pay per year of service up
to an amount of a maximum payment of 26 weeks of base pay. If the employee signs
a Waiver and Release of Claims Agreement, the severance pay benefits are
doubled. The plan provides a grandfather provision for those employees whose
employment date is prior to January 1, 1993. This provision provides a severance
benefit equal to two weeks of base pay multiplied by the number of full or
partial years of service, plus two weeks of base pay for each $10,000 (or
portion of $10,000) included in the employee's annual base pay, provided the
employee signs a Waiver and Release of Claims Agreement. In the event of an
unapproved change of control of the Company, any employee who is involuntarily
terminated within two years following the change of control will be eligible for
severance benefits equal to two weeks of base pay multiplied by the number of
full or partial years of service, plus two weeks of base pay for each $10,000
(or portion of $10,000) included in the employee's annual base pay. Under no
circumstances will the total severance pay benefit exceed 52 weeks of pay.

     Severance arrangements for Mr. Luce, Mr. Duffy, Mr. Huth, and Ms. Coombe
include an involuntary termination provision pursuant to which the executive
officer will receive severance pay equal to up to two years base salary. An
involuntary termination includes (a) termination without cause; (b) a
termination within 90 days after the happening of one of the following events
without the approval of the executive officer: (i) a substantial 


                                       40
<PAGE>   41

and/or material reduction in the nature or scope of the executive officer's
duties and/or responsibilities, which results in the executive officer no longer
having an officer status and results in an overall material and substantial
reduction from the duties and stature of the officer position he presently
holds, which reduction remains in place and uncorrected for 30 days following
written notice of such breach to the General Partner by the executive officer,
(ii) a reduction in the executive officer's base pay or an exclusion from a
benefit plan or program (except the executive officer may be subject to
exclusion from a benefit plan or program as part of a general cutback for all
employees or officers) or (iii) a change in the location for the primary
performance of the executive officer's services under the agreement to a city
which is more than 100 miles away from such location; and (c) a termination by
the executive officer within one year after a change of control of the General
Partner if one of the events described in (b) has occurred. The severance
agreement, the confidential information and noncompete provisions will continue
for one year.

Employment Agreements

     Mr. Burke entered into an Employment Agreement with EOTT Energy Corp. in
May 1998. The Agreement has a term through December 31, 2001 for an annual base
salary of $340,000. In addition, the Agreement provides for 90,828 units under
the EOTT Energy Long Term Incentive Plan, options to purchase 400,000
Subordinated Units under the EOTT Energy Unit Option Plan and options to
purchase 50,000 shares of Enron Corp. Common Stock under the Enron Corp. Stock
Plan. The Agreement contains involuntary termination provisions which include
severance benefits equal to one year's base pay plus a payment of a pro-rata
amount of bonus opportunity for the year of termination based on the higher of
the target bonus amount for the termination year or the amount of bonus paid for
the preceding year payable within 30 days of termination. In addition, an amount
equal to one year's base salary is payable one year following the involuntary
termination date. Upon Change of Control termination prior to the expiration of
term, the severance benefits include an amount equal to the sum of annualized
monthly base pay plus a bonus factor multiplied by 2.99. The bonus factor shall
be the greater of the target bonus for the year in which Change of Control
termination occurs or the actual amount of the previous year's annual bonus. The
Agreement provides for post-employment non-competition obligations for twelve
months after the date of Involuntary Termination or Change of Control
Termination.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To EOTT Energy Partners, L.P.:

We have audited the accompanying consolidated balance sheets of EOTT Energy
Partners, L.P. (a Delaware limited partnership) as of December 31, 1998 and
1997, and the related consolidated statements of operations, cash flows and
partners' capital for each of the three years in the period ended December 31,
1998. These financial statements and the schedule referred to below are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements and schedule 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, the financial statements referred to above present fairly, in
all material respects, the financial position of EOTT Energy Partners, L.P. as
of December 31, 1998 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The financial statement schedule listed
in the index to financial statements is presented for purposes of complying with
the Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   BASIS OF PRESENTATION

     In connection with a reorganization of the business conducted by EOTT
Energy Corp., an indirect wholly-owned subsidiary of Enron Corp. (Enron or the
Parent), into limited partnership form and a concurrent initial public offering
of Common Units of EOTT Energy Partners, L.P. (EOTT or the Partnership)
effective March 24, 1994, the net assets of EOTT Energy Corp. and its
wholly-owned foreign subsidiary, EOTT Energy Ltd., and Enron Products Marketing
Company (EPMC) (collectively referred to as the Predecessor) were acquired by
several operating limited partnerships in which the Partnership is directly or
indirectly the 99% limited partner. EOTT Energy Corp. serves as the General
Partner of the Partnership and its related operating limited partnerships.

     On March 24, 1994, the General Partner completed an initial public offering
of 10 million Common Units at $20.00 per Unit, representing limited partner
interests in the Partnership of approximately 58%. At December 31, 1998 the
General Partner owned an approximate 2% general partner interest in the
Partnership and an approximate 29% subordinated limited partner interest. Enron,
through its ownership of EOTT Common Units, holds an approximate 14% interest in
the Partnership.

     The accompanying consolidated financial statements and related notes
present the financial position as of December 31, 1998 and 1997 for the
Partnership, and the results of its operations, cash flows and changes in
partners' capital for the years ended December 31, 1998, 1997 and 1996.

     Certain reclassifications have been made to prior period amounts to conform
with the current period presentation.

     Unless the context otherwise requires, the term EOTT hereafter refers to
the Partnership and its affiliated limited partnerships.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation. The Partnership owns and operates its assets
through operating limited partnerships. The accompanying financial statements
reflect the combined accounts of the Partnership and the operating partnerships
after elimination of intercompany transactions.

     Nature of Operations. Through its affiliated limited partnerships, EOTT
Energy Operating Limited Partnership, EOTT Energy Canada Limited Partnership,
and EOTT Energy Pipeline Limited Partnership, EOTT is engaged in the purchasing,
gathering, transporting, trading, storage and resale of crude oil and refined
petroleum products and related activities. As discussed further in Note 19, EOTT
has changed the composition of its reportable segments and restated segment
information for previous periods. EOTT's principal business segments are its
North American Crude Oil - East of Rockies gathering and marketing operations,
Pipeline Operations and West Coast Operations. In late 1997, EOTT exited the
East of Rockies refined products business which is discussed further in Note 5.

     Cash Equivalents. EOTT records as cash equivalents all highly liquid 
short-term  investments  having original maturities of three months or less.

     Inventories. In the second quarter of 1996, the Partnership changed its
method of accounting for inventories from the last-in, first-out ("LIFO") method
to the average cost method. The change did not have a significant


                                      F-7

<PAGE>   55

                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


effect on the results of operations for 1996. The change was made to conform the
inventory costing method used for financial reporting purposes to that used by
the Partnership to manage its commercial operations.

     Depreciation and Amortization. Depreciation is provided by applying the
straight-line method to the cost basis of property, plant and equipment, less
estimated salvage value, over the estimated useful lives of the assets. Asset
lives are 15 to 20 years for pipeline and gathering facilities, 5 to 10 years
for transportation equipment, 15 to 20 years for barge and terminalling
facilities and 3 to 20 years for other facilities and equipment.

     Goodwill and non-compete agreements are amortized over a period of 3 to 15
years, and are recorded net of their accumulated amortization in Other Assets.
Accumulated amortization of goodwill and non-compete agreements at December 31,
1998 and 1997 was $27.9 million and $25.7 million, respectively.

     Foreign Currency Transactions. Canadian operations represent all of the
foreign activities of EOTT. The U.S. dollar is the functional currency. Foreign
currency transactions are initially translated into U.S. dollars. Gains and
losses resulting therefrom are included in the determination of net income
(loss) in the period in which the exchange rate changes.

     Hedging Activities/Revenue Recognition. EOTT enters primarily into futures
and over-the-counter transactions in an effort to minimize the impact of market
fluctuations on inventories and other contractual commitments. Realized and
unrealized changes in the market value of these transactions, which are entered
into and accordingly designated as hedges, are deferred until the gain or loss
on the hedged transaction is recognized in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 80. Any cash flow recognition
resulting from hedging activities is treated in the same manner as the
underlying transaction. Based on the historical correlations between the New
York Mercantile Exchange ("NYMEX") price for West Texas Intermediate crude at
Cushing, Oklahoma and the various trading hubs at which EOTT trades, EOTT
management believes the hedging program has been effective in minimizing the
overall price risk. EOTT continuously monitors the basis differentials between
its various trading hubs and Cushing, Oklahoma to further manage its basis
exposure.

     It is EOTT's policy to seek to maintain at all times purchase and sale
positions that are substantially balanced in order to minimize exposure to price
fluctuations and to lock in margins, although certain risks cannot be fully
hedged. EOTT has certain basis risks (the risk that price relationships between
delivery points, classes of products or delivery periods will change) which
cannot be completely hedged.

     Periodically, EOTT enters into agreements to sell United States dollars for
Canadian dollars to hedge commitments to sell petroleum in the United States
that is purchased in Canada. Any gains or losses resulting from these
commitments are recorded with the purchase and sale of crude oil and are
included in the determination of net income (loss).

     EOTT recognizes revenue on the accrual method based on the right to receive
payment for goods and services delivered to third parties.

     Derivatives. In addition to hedging its lease barrel purchases, EOTT
provided price risk management products to its energy customer base. Activities
for trading purposes were accounted for using the mark-to-market method of
accounting and the gain or loss recorded to cost of sales in the period of
change in the market. Trading activities were immaterial to EOTT's financial
position and results of operations for 1998, 1997 and 1996. Activities for
non-trading purposes consist of transactions entered into to hedge the impact of
market fluctuations on assets, liabilities, or contractual commitments. Changes
in the market value of these transactions

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


are deferred until the gain or loss on the hedged item is recognized. See Note
17 for further discussion of EOTT's price risk management activities. In
connection with the realignment initiatives discussed in Note 5, EOTT is no
longer providing price risk management products to customers.

     Use of Estimates. The preparation of these financial statements required
the use of certain estimates by management in determining the entity's assets,
liabilities, revenue and expenses. Actual results may differ from these
estimates.

3.   ACQUISITION OF ASSETS

     On February 1, 1997, the Partnership acquired over 400 miles of intrastate
and interstate common carrier pipelines in Louisiana and Texas from CITGO
Pipeline Company. Shipped volumes associated with these assets amount to
approximately 48,000 barrels per day from leases in certain regions of Arkansas,
Louisiana and Texas. Storage associated with the pipeline systems totals
approximately 0.5 million barrels. The purchase price was approximately $12
million and was financed with a note payable from Enron.

     On July 1, 1998, the Partnership acquired crude oil gathering and
transportation assets in West Texas and New Mexico from Koch Pipeline Company,
L.P., a subsidiary of Koch Industries, Inc., and Koch Oil Company, a division of
Koch Industries, Inc. (collectively "Koch"). The asset purchase included
approximately 300 miles of common carrier pipelines, associated storage
facilities for approximately 500,000 barrels and lease purchase contracts for up
to 40,000 lease barrels of crude oil per day. The purchase price was
approximately $28.5 million and was financed with short-term borrowings from
Enron.

     On December 1, 1998, the Partnership acquired certain additional crude oil
gathering and transportation assets in key oil producing regions from Koch. The
asset purchase included approximately 3,900 miles of active crude oil pipelines,
crude oil transport trucks, meter stations, vehicles, storage tanks and lease
purchase contracts for approximately 180,000 lease barrels of crude oil per day
from production in 11 central and western states including Texas, Oklahoma,
Kansas and California (the "Assets"). The transaction almost tripled EOTT's
pipeline mileage and almost doubled crude oil lease barrels under contract. The
total purchase price of the Assets was $235.6 million, which includes
consideration of $184.5 million in cash, 2,000,000 Common Units, 2,000,000
Subordinated Units and $11.4 million in transaction costs. EOTT financed the
majority of the purchase price through borrowings from Enron, consisting of a
$42 million bridge loan due December 31, 1999, $135.7 million of term debt, due
December 31, 1999, and $6.8 million from the Partnership's existing credit
facility with Enron. EOTT also increased its existing credit facility with Enron
to $1 billion in order to provide increased credit support for the Partnership
because of its increased size following the Koch acquisitions. See additional
discussion regarding Enron financing in Note 7.

     Since the Assets were historically used to support Koch's integrated
revenue producing activities, EOTT does not believe that the historical
operational results of the Assets provide a meaningful basis for evaluating the
results of operations that the Assets acquired would have realized had they been
part of EOTT. Therefore, summarized pro forma results of the Partnership as
though the acquisition of Assets had occurred at January 1, 1998 have not been
provided.

4.   EARNINGS PER UNIT

     In the fourth quarter of 1997, EOTT adopted Statement of Financial
Accounting Standards ("SFAS") No. 128, "Earnings Per Share". SFAS No. 128
requires the presentation of "Basic" and "Diluted" earnings per unit in lieu of
"Primary" and "Fully Diluted" earnings per unit and requires restatement of
prior years' net


                                      F-9
<PAGE>   57


                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


income (loss) per unit to conform to the new computation and presentation
guidelines. Basic earnings per unit differs from primary earnings per unit in
that it only includes the weighted average impact of outstanding units of EOTT
(i.e., it excludes unit equivalents). Diluted earnings per unit considers the
impact of all potentially dilutive securities. The impact of the restatement for
all years under SFAS No. 128 was to have two classes of Units (Common Units,
with Special Units considered Common Units, and Subordinated Units) in the basic
earnings per unit calculation and diluted earnings per unit is calculated
assuming the Subordinated Units converted into Common Units.

     Net income (loss) shown in the table below excludes the approximate two
percent interest of the General Partner. Earnings (loss) per unit are calculated
as follows (in millions, except per unit amounts):

</TABLE>

(1)     Net income (loss), excluding the two percent General Partner interest,
        has been apportioned to each class of Unitholder based on the ownership
        of total Units outstanding in accordance with the Partnership Agreement,
        which is also reflected on the Statement of Partners' Capital, and
        Special Units are considered Common Units. Due to a negative capital
        account balance for the Common Unitholders during the second and third
        quarters of 1998, the loss allocated to the Common Unitholders
        attributable to these periods was reallocated to the remaining
        Unitholders based on their ownership percentage. The allocated loss will
        be recouped by the Unitholders allocated the additional losses through
        future income.

(2)     The diluted earnings (loss) per unit calculation assumes the conversion
        of Subordinated Units into Common Units.


5.   REALIGNMENT INITIATIVES

     In late 1997, EOTT decided to refocus on the core crude business, which
provides substantially all of the gross margin for the Partnership, as well as
improve overall operating efficiencies. As a result, EOTT announced the
following two initiatives. The decision was made to exit the marginal East of
Rockies refined products business in order to focus on business development
opportunities in the crude business, where management believes there is more
potential for growth. The Partnership re-deployed the working capital associated
with the East of Rockies refined products business and intends to sell its three
products terminals in Ohio. In connection with this decision, non-recurring
charges were recorded at December 31, 1997, which included severance costs of
$0.9 million and a $1.5 million impairment of the Ohio products terminals.

     In addition, EOTT streamlined business processes throughout the
organization and realigned reporting responsibilities to improve the
Partnership's overall cost structure. As a result, marketing and administrative
personnel were reduced by approximately 20 percent and an additional
non-recurring severance charge of $1.1 million was recorded at December 31, 1997
pursuant to the existing EOTT Energy Corp. Severance Plan.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


6.   IMPAIRMENT OF ASSETS

     As a result of the decision to exit the East of Rockies refined products
business discussed in Note 5, the Partnership's three Ohio products terminals
are being held for sale. At December 31, 1997, a $1.5 million impairment charge
was recorded.

     During the fourth quarter of 1997, EOTT terminated an information system
development project due to the lack of third party vendor support and
foreseeable operating platform obsolescence. As a result, the Partnership
recorded a $6.5 million impairment charge.

7.   CREDIT RESOURCES AND LIQUIDITY

     In 1995, Enron Corp. agreed to provide credit support (the "Credit
Facility") to the Partnership in the form of guarantees, letters of credit,
loans and letters of indemnity. The total amount of the credit support was $600
million, as amended December 19, 1996, had a maturity of March 31, 1999 and was
replaced with a new facility on December 1, 1998 as discussed below. As amended,
the agreement contained sublimits on the availability of the Credit Facility of
$100 million for working capital loans and $200 million for letters of credit.
Letter of credit fees were based on actual charges by the banks which range from
 .20% - .375% per annum. Interest on outstanding loans was charged at the London
Interbank Offering Rate ("LIBOR") plus 25 basis points per annum. At December
31, 1997, EOTT had a note payable of $39.3 million with Enron under a financing
arrangement for acquisitions and other capital projects (the "Note Payable").
This financing was provided at a rate of LIBOR plus 30 basis points per annum.
The maturity date of the Note Payable was March 31, 1999 and was redeemed and
reissued under the term loan discussed below.

     On December 1, 1998, Enron increased its existing credit facility with the
Partnership to provide additional credit support (the "Enron Facility") in the
form of guarantees, letters of credit and working capital loans through December
31, 2001. The total amount of the Enron Facility is $1.0 billion and contains
sublimits on the availability of the Enron Facility of $100 million for working
capital loans and $900 million for guarantees and letters of credit. Letter of
credit fees are based on actual charges by the banks which range from .20% -
 .375% per annum. Interest on outstanding loans is charged at LIBOR plus 250
basis points per annum.

     The Enron Facility is subject to defined borrowing base limitations
relating to the Partnership's activities and to the maintenance and protection
of the collateral. The Enron Facility permits distributions to Unitholders
subject to certain limitations based on the Partnership's earnings and other
factors. These covenants and restrictions are not expected to materially affect
EOTT's ability to operate the ongoing Partnership business.

     At December 31, 1998, EOTT had an additional $175 million of debt (the
"Term Loan") outstanding with Enron under a financing arrangement to fund a
portion of the cash consideration paid to Koch for the assets purchased in 1998
and to refinance indebtedness incurred in prior acquisitions. The Term Loan
matures on December 31, 1999. The interest rate on the Term Loan is LIBOR plus
300 basis points.

     The Enron Facility and Term Loan are secured by a first priority lien on
and security interest in all receivables and inventory of the Partnership. The
borrowing base is the sum of cash and cash equivalents, specified percentages of
eligible receivables, inventory, and products contracted for or delivered but
not billed. The Enron Facility and Term Loan are non-recourse to the General
Partner and the General Partner's assets. The Partnership is restricted from
entering into additional financing arrangements without the prior approval of
Enron.


                                      F-11
<PAGE>   59
                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     In addition, at December 31, 1998, EOTT had $42.0 million of debt
outstanding with Enron under a $100 million bridge loan (the "Bridge Loan") to
finance a portion of the cash consideration for the acquisition of assets from
Koch. The interest rate on the Bridge Loan is initially LIBOR plus 400 basis
points. At the end of each three-month period, the spread on the Bridge Loan
will increase by 25 basis points. The Bridge Loan is unsecured and matures on
December 31, 1999.

     As discussed above, the interim Bridge Loan ($42 million) and Term Loan
($175 million) provided by Enron are due December 31, 1999. The General Partner
intends to refinance the Bridge Loan and Term Loan on a long-term basis before
maturity. The General Partner anticipates that the debt will be refinanced using
a combination of financing alternatives including (a) third party bank debt, (b)
private placement of debt, (c) an offering of high yield debt and/or (d) an
equity offering utilizing some portion of the additional 10 million Common Units
which were authorized to be issued subsequent to year end (See Note 20).

     At December 31, 1998, EOTT had $44.4 million in letters of credit and $28.3
million in loans outstanding under the Enron Facility at an average annual
interest rate of approximately 6.1%. The amount outstanding at December 31, 1998
under the Term Loan was $175.0 million with an average annual interest rate of
8.5% and under the Bridge Loan was $42.0 million with an average annual interest
rate of 9.5%. The actual interest rate may vary based on the length of the
borrowings. In addition, guarantees outstanding totaled $366.4 million of which
$290.9 million were used.

     At December 31, 1997, EOTT had $92.5 million in letters of credit and $70.0
million in loans outstanding under the Credit Facility at an average annual
interest rate of approximately 5.8%. The amount outstanding under the Note
Payable at December 31, 1997 was $39.3 million with an average annual interest
rate of 6.0%. The actual interest rate may vary based on the length of the
borrowings. In addition, guarantees outstanding totaled $402.5 million of which
$292.3 million were used.

     At December 31, 1997, EOTT was in technical violation of the negative
covenants relating to the Tangible Net Worth, Leverage Ratio and Working Capital
Ratio in the Credit Facility and Note Payable due principally to the operating
loss associated with the deterioration of grade and basis differentials in the
crude oil markets. EOTT received a waiver for these violations from Enron.

     The General Partner believes that the Enron Facility, Bridge Loan, Term
Loan and subsequent refinancing discussed above will be sufficient to support
the Partnership's crude oil purchasing activities and working capital and
liquidity requirements. No assurance, however, can be given that the General
Partner will not be required to reduce or restrict the Partnership's gathering
and marketing activities because of limitations on its ability to obtain credit
support and financing for its working capital needs.

     The Partnership's ability to obtain letters of credit to support its
purchases of crude oil or other petroleum products is fundamental to the
Partnership's gathering and marketing activities. Additionally, EOTT has a
significant need for working capital due to the large dollar volume of marketing
transactions in which it engages. Any significant decrease in the Partnership's
financial strength, regardless of the reason for such decrease, may increase the
number of transactions requiring letters of credit or other financial support,
make it more difficult for the Partnership to obtain such letters of credit,
and/or increase the cost of obtaining them. This could in turn adversely affect
the Partnership's ability to maintain or increase the level of its purchasing
and marketing activities or otherwise adversely affect the Partnership's
profitability and Available Cash as defined in EOTT's Partnership Agreement and
amendments thereto.

     Generally, the Partnership will distribute 100% of its Available Cash
within 45 days after the end of each quarter to Unitholders of record and to the
General Partner. Available Cash consists generally of all of the cash receipts
of the Partnership adjusted for its cash distributions and net changes to
reserves. The full definition of

Available Cash is set forth in the Partnership Agreement and amendments thereto,
a form of which is filed or has been previously filed as an exhibit to this
Annual Report on Form 10-K. Distributions of Available Cash to the Subordinated
Unitholders are subject to the prior rights of the Common and Special
Unitholders to receive the Minimum Quarterly Distribution ("MQD") for each
quarter during the Subordination Period, and to receive any arrearages in the
distribution of the MQD on the Common Units for prior quarters during the
Subordination Period.

     MQD is $0.475 per Unit. As discussed in Note 20, Enron has committed to
provide total cash distribution support in an amount necessary to pay MQDs, with
respect to quarters ending on or before December 31, 2001, in an amount up to an
aggregate of $29 million in exchange for Additional Partnership Interests
("APIs"). See further discussion in Note 12 regarding the contribution of $21.9
million in APIs subsequent to year-end.

     The Partnership Agreement authorizes EOTT to cause the Partnership to issue
additional limited partner interests, the proceeds from which could be used to
provide additional funds for acquisitions or other Partnership needs.

     At December 31, 1998, EOTT has outstanding forward commodity repurchase
agreements of approximately $83.0 million. Pursuant to the agreements, which had
terms of thirty days, EOTT repurchased the crude oil inventory on January 20,
1999 for approximately $83.4 million.

market price structures and continued development drilling in certain areas of
the United States. EOTT continuously monitors these factors and pursues
alternative strategies to maintain or enhance cash flows associated with these
assets; however, no assurances can be given that EOTT can mitigate the effects,
if any, on future cash flows related to any changes in these factors.

10.  SUPPLEMENTAL CASH FLOW INFORMATION

     Cash paid for interest expense was $8.9 million, $6.2 million and $3.4
million for the years ended December 31, 1998, 1997 and 1996,respectively.

     On January 5, 1996, EOTT repaid the outstanding balance of the financing in
connection with the information systems development. As discussed further in
Note 12, 1,830,011 Common Units issued to Enron in connection with the Amerada
Hess Acquisition were exchanged for Special Units.

     On December 1, 1998, EOTT issued 2,000,000 Common Units and 2,000,000
Subordinated Units to Koch Pipeline as a portion of the consideration paid for
the Assets. See further discussion of the acquisition of Assets in Note 3.

     As discussed further in Note 3, the Partnership issued 2,000,000 Common
Units and 2,000,000 Subordinated Units to Koch in connection with the
acquisition of Assets. In addition, subsequent to year-end as discussed in Note
20, the Partnership obtained approval to issue an additional 10 million Common
Units to raise cash to reduce indebtedness, for acquisitions and for other
Partnership purposes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     Pursuant to a Support Agreement, discussed in Note 12, the Partnership
issued 1,150,000 Special Units to Enron in exchange for Enron's commitment to
contribute $21.9 million in APIs outstanding at December 31, 1998 on the earlier
of the date certain proposals were approved by the Unitholders or May 17, 1999.
At December 1, 1998, the Partnership issued 1,150,000 Special Units for a value
of approximately $15.9 million and recorded a contribution receivable from
Enron. As discussed in Note 20, subsequent to year-end, Enron contributed the
$21.9 million in APIs outstanding pursuant to its commitment made in connection
with the Support Agreement. In addition, the Special Units were converted into
Common Units in February 1999.

12.  TRANSACTIONS WITH ENRON AND RELATED PARTIES

     Revenue and Cost of Sales. A summary of revenue and cost of sales with
Enron and its affiliates follows (in thousands):

Purchases from affiliates ....     $232,486     $ 71,895     $100,143
</TABLE>

     Revenue in 1998, 1997 and 1996 consists primarily of sales of crude oil to
Enron Reserve Acquisition Corp. and natural gas liquids to Enron Gas Liquids,
Inc. Cost of sales consists primarily of crude oil and condensate purchases from
Enron Oil & Gas Company and Enron Reserve Acquisition Corp. and natural gas
liquids purchases from Enron Gas Liquids, Inc. These transactions in the opinion
of management are no more or less favorable than can be obtained from
unaffiliated third parties.

     Other related party balances related to purchases and sales of goods and
services have been classified as trade and other receivables or trade accounts
payable. Related party receivables at December 31, 1998 and 1997 were $0.2
million and $2.8 million, respectively. Related party payables at December 31,
1998 and 1997 were $1.6 million and $3.6 million, respectively. The payables
primarily represent amounts owed by EOTT on the purchase of crude oil and other
products from Enron affiliates.

     General and Administrative. As is commonly the case with publicly traded
partnerships, EOTT does not directly employ any persons responsible for managing
or operating the Partnership or for providing services relating to day-to-day
business affairs. The General Partner, under a corporate services agreement,
provides services to the Partnership including liability and casualty insurance
and certain data processing services. The General Partner is reimbursed by the
Partnership for these direct and indirect costs. Those costs were $3.3 million,
$3.6 million and $5.0 million for the years ended December 31, 1998, 1997 and
1996, respectively. Management believes that the charges were reasonable.

     Purchase of Common Units. On March 10, 1995, Enron authorized the purchase
of up to $15 million of EOTT units on the open market. As of February 15, 1998,
Enron had purchased 296,800 EOTT Common Units under the purchase program,
excluding the 3.0 million units discussed below.

     Financing of Acquisitions. In February 1997, the Partnership acquired
intrastate and interstate common carrier pipelines from CITGO Pipeline Company
for approximately $12 million which was financed with a note payable from Enron.
As discussed further in Note 3, on July 1, 1998 and December 1, 1998, the
Partnership acquired crude oil gathering and transportation assets from Koch
which was financed primarily with borrowings from Enron.

                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Support Agreement. Pursuant to a Support Agreement dated September 21, 1998
(a) Enron agreed to make loans to the Partnership to fund the cash portion of
the consideration to be paid to Koch for the Assets at closing as discussed in
Note 3 and to refinance indebtedness incurred in a prior acquisition of assets
from Koch on July 1, 1998, (b) Enron agreed to increase and extend the
Partnership's credit facility with Enron to $1 billion through December 31,
2001, (c) the Partnership agreed to issue 1,150,000 Special Units to Enron, (d)
Enron agreed to contribute $21.9 million in APIs to the Partnership on the
earlier of the date certain proposals, discussed further below, are approved by
the Unitholders at a special meeting of Unitholders or May 17, 1999, (e) Enron
agreed that if certain proposals are approved by the Unitholders it will extend
its cash distribution support through the fourth quarter of 2001, and (f) the
Partnership agreed that, if any additional APIs are issued prior to approval of
certain proposals by the Unitholders, it will issue additional Common Units at
$19.00 per share in exchange for such additional APIs. As discussed further in
Note 20, the Partnership obtained Unitholder approval of these proposals
subsequent to year-end. Pursuant to the Support Agreement, EOTT borrowed from
Enron a $42 million Bridge Loan and $175 million Term Loan and entered into a $1
billion credit facility with Enron, to replace its existing $600 million credit
facility.

     Special Units. Effective July 16, 1996, EOTT created a new class of limited
partner interest designated as Special Units and exchanged the Special Units on
a one-for-one basis for the 1,830,011 Common Units issued January 3, 1996 to
Enron in connection with the financing of a previous acquisition. The Special
Units ranked pari passu with the Common Units in all distributions and upon
liquidation and will vote as a class with the Common Units. The exchange
permitted EOTT to avoid the cost of New York Stock Exchange listing of the
Common Units issued to Enron in connection with the financing of the
acquisition, including the cost associated with seeking Unitholder approval for
the listing. In connection with the Support Agreement, the Partnership issued
1,150,000 Special Units to Enron and as discussed further below Enron
contributed $21.9 million APIs to the Partnership subsequent to year end. The
Special Units became convertible into Common Units on a one-for-one basis and
were converted into Common Units during the first quarter of 1999. The Special
Units are considered Common Units for earnings per unit purposes, and the
exchange had no adverse impact on EOTT or on income or distributions per Common
Unit.

     Additional Partnership Interests. On November 14, 1997, February 13, 1998,
May 15, 1998 and August 14, 1998, Enron paid $3.7 million, $3.8 million, $2.8
million and $2.5 million, respectively, in support of EOTT's third and fourth
quarter 1997 and first and second quarter 1998 distributions to its Common and
Special Unitholders and the General Partner. In exchange for the distribution
support, Enron received APIs in the Partnership. APIs have no voting rights and
are non-distribution bearing; however, APIs will be entitled to be redeemed if,
with respect to any quarter, the MQD and any Common Unit Arrearages have been
paid, but only to the extent that Available Cash with respect to such quarter
exceeds the amount necessary to pay the MQD on all Units and any Common Unit
Arrearages. In February 1997, the General Partner amended the Partnership
Agreement to provide that a holder of APIs may, at its option, waive its right
to receive distributions of Available Cash to which it would otherwise be
entitled and to provide that in such case the Partnership may retain such cash
for later distribution to partners or for use in the Partnership's business in
subsequent periods. The Partnership's Available Cash for the fourth quarter of
1996 was substantially in excess of the amount necessary to distribute the MQD
on all outstanding Units, and upon adoption of the amendment, Enron, the holder
of APIs, waived its right to receive such excess cash in redemption of APIs. The
February 1997 amendments to the Partnership Agreement also provided that after
the end of the Subordination Period a holder of Subordinated Units may convert
such Units into Common Units either in whole or in part from time to time. The
amendments also provided that any unconverted Units will be renamed "Class B
Units" after the end of the Subordination Period. Prior to the amendments, the
Partnership Agreement provided that conversion would occur only on an all or
none basis. Enron had committed to support payment of EOTT Common and Special
Unit distributions through March 1999, as necessary (of which $7.1 million was
still available to be advanced at December 31, 1998). As discussed in Note 20,
certain Unitholder approvals were obtained subsequent to year end and as a

result, Enron increased its cash distribution support to $29 million and
extended it through the fourth quarter of 2001 and contributed the $21.9 million
in APIs currently outstanding pursuant to its commitment made in connection with
the Support Agreement.


13.  EMPLOYEE BENEFIT AND RETIREMENT PLANS

     Employees of the General Partner are covered by various retirement, stock
purchase and other benefit plans of Enron. In April 1993, the General Partner
adopted non-qualified benefit plans providing medical, dental, life, accidental
death and dismemberment and long-term disability coverage to employees, with all
related premiums and costs being incurred by the General Partner. Total benefit
costs for 1998 were $6.4 million, including $3.9 million in costs attributable
to health and welfare benefit plans. Total benefit costs for 1997 were $4.2
million including $3.3 million in costs attributable to health and welfare
benefit plans. Total benefit costs for 1996 were $ 6.3 million including $ 3.1
million in costs attributable to health and welfare benefit plans and $1.8
million in costs attributable to a profit sharing contribution to the Enron
Corp. Savings Plan based on 1996 financial results.

     Additionally, the General Partner maintains a variable pay plan based on
earnings before interest, income taxes, depreciation and amortization of which
none was recognized in 1998 and 1997, and $8.9 million in 1996.

     The General Partner's employees continue benefit accrual under the Enron
Cash Balance Plan. All accrued benefits under the Enron Cash Balance Plan will
be preserved in the Enron Cash Balance Plan until the General Partner adopts
separate plans or participating employees are eligible for distribution under
the plan. The General Partner's employees continue to participate in the Enron
Employee Stock Ownership Plan and continue to be eligible for participation in
the Enron Corp. Savings Plan.

     As of September 30, 1998, the most recent valuation date, the plan net
assets, including contributions to the trust during the fourth quarter of 1998,
of the Enron noncontributory defined benefit plan, in which the employees of the
General Partner participate, were less than the actuarial present value of
projected plan benefit obligations by approximately $25.0 million. As of
September 30, 1997, the plan assets, including contributions to the trust during
the fourth quarter of 1997, of the Enron noncontributory defined benefit plan,
in which the employees of the General Partner participate, were less than the
actuarial present value of projected plan benefit obligations by approximately
$6.5 million. The assumed discount rate, rate of return on plan assets and rate
of increases in wages used in determining the actuarial present value of
projected benefits were 6.75%, 10.5%, and 4.0% in 1998, respectively, and 7.25%,
10.5%, and 4.0% in 1997 respectively.

     The General Partner provides certain postretirement medical, life insurance
and dental benefits to eligible employees who retire after January 1, 1994.
Benefits are provided under the provisions of contributory defined dollar
benefit plans for eligible employees and their dependents. EOTT accrues these
postretirement benefit costs over the service lives of employees expected to be
eligible to receive such benefits. Enron retains liability for former employees
of the General Partner who retired prior to January 1, 1994. The accumulated
postretirement benefit obligation ("APBO") existing at December 31, 1998 and
1997 totaled $1.1 million and $0.7 million, respectively. The measurement of the
APBO assumes a 6.75% and 7.25% discount rate in 1998 and 1997, respectively.
EOTT does not currently intend to prefund its obligations under the Enron
postretirement benefit plan.

     EOTT adopted SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits," in 1998. This statement changed the disclosure
requirements, but not the method of measurement or

recognition of these obligations. Prior year disclosures have been restated to
conform with the new disclosure guidelines under SFAS No. 132. The following

changes in plan assets, a reconciliation of the funded status of the plans and

     The General Partner provides unemployment, severance and disability-related
benefits or continuation of benefits such as health care and life insurance and
other postemployment benefits. SFAS No. 112 requires the cost of those benefits
to be accrued over the service lives of the employees expected to receive such
benefits. At December 31, 1998 and 1997, the liability accrued was $0.7 million
and $0.5 million, respectively.

     EOTT Energy Corp. Unit Option Plan. In February 1994, the Board of
Directors of the General Partner adopted the 1994 EOTT Energy Corp. Unit Option
Plan (the "Unit Option Plan"), which is a variable compensatory plan. To date,
no compensation expense has been recognized under the Unit Option Plan. Under
the Unit Option Plan, selected employees of the General Partner may be granted
options to purchase Subordinated Units at a price of $15.00 per Unit as
determined by the Compensation Committee of the Board of Directors of the
General Partner. Options granted under the Unit Option Plan vest to the
employees over a five-year service period and will expire on the tenth
anniversary of the date of grant. No options are vested or exercisable prior to
the third anniversary of the grant.

     In February 1997, the Board of Directors of the General Partner decided
that it would not grant any additional options under the Unit Option Plan. In
May 1998, options forfeited by a former officer were approved for reissuance by
the Board of Directors to the current President and Chief Executive Officer. In
addition, in February 1997, the Unit Option Plan was amended to provide that, if
the General Partner and the option holder agree, any option may be exercised on
a "net" basis with no cash payment (other than for withholding taxes), so that
upon exercise the holder will receive a number of Units with a fair market value
equal to the difference between the fair market value of the Units covered by
the option and the exercise price of the option. As a result, the General
Partner anticipates that the actual number of Units to be issued on exercise of
options will be substantially less than the number of Units covered by
outstanding options.

     In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation." This standard establishes a fair
value based method of accounting for stock based compensation plans awarded
after December 31, 1995 and encourages companies to adopt the fair value based
method in SFAS No. 123 in place of the existing accounting method which requires
expense recognition only in situations where stock based compensation plans
award intrinsic value to recipients at the date of grant. Companies that do not
follow SFAS No. 123 for accounting purposes must make annual pro forma
disclosure of its effects. EOTT elected not to adopt the fair value method for
accounting purposes. If EOTT had elected to recognize compensation cost based on
the fair value of the options granted at grant date as prescribed by SFAS No.
123, net income (loss) and net income (loss) per diluted Unit would have been
reduced to the following pro forma amounts (in thousands):

expected life of option of 2 years. The fair value of each option grant for 1996
is estimated on the date of grant using the Cox-Ross-Rubenstein binomial method
with the following assumptions: (1) dividend of $1.90 per Common Unit, (2)
expected unit price volatility of 24.03%, (3) risk-free interest rate of 6.40%
and (4) expected life of option of 3 years. The weighted average fair value of
options granted during 1998 was $2.119 per unit and during 1996 was $2.065 per
unit.

     EOTT Energy Corp. Long-Term Incentive Plan. In October 1997, the Board of
Directors adopted the EOTT Energy Corp. Long Term Incentive Plan ("Plan"), which
is a variable compensatory plan. Under the Plan, selected key employees are
awarded Phantom Appreciation Rights ("PAR"). Each PAR is a right to receive cash
based on the performance of the Partnership prior to the time the PAR is
redeemed. Performance of the Partnership is measured primarily by calculating
the change in the average of Earnings Before Interest on Debt, related to
acquisitions, Depreciation and Amortization ("EBIDA"), for each of the three
consecutive fiscal years immediately preceding the grant date of the PAR and the
exercise date of the PAR. The Plan has a five-year term beginning January 1,
1997, and PAR awards vest in 25% increments in the four-year period following
the grant year.

years ended December 31, 1998 and 1997:

14.  LITIGATION AND OTHER CONTINGENCIES

      EOTT is, in the ordinary course of business, a defendant in various
lawsuits, some of which are covered in whole or in part by insurance. The
Partnership is responsible for all litigation and other claims relating to the
business acquired from the Predecessor, although the Partnership will be
entitled to the benefit of certain insurance maintained by Enron covering
occurrences prior to the closing of the offering. The Partnership believes that
the ultimate resolution of litigation, individually and in the aggregate, will
not have a materially adverse impact on the Partnership's financial position or
results of operations. Various legal actions have arisen in the ordinary course
of business, the most significant of which are discussed below.

     Wyoming Refining Company Matter. EOTT had a possible loss exposure of
approximately $1.47 million as a result of a dispute between Wyoming Refining
Company ("WRC") and the U.S. Minerals Management Service ("MMS"). MMS was
claiming that it was underpaid by WRC for certain Montana crude oil which was
delivered to WRC over a several-year period prior to 1993. On December 14, 1998,
EOTT received a letter from WRC stating that the MMS had withdrawn its claim and
no price adjustments would be necessary.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     State of Texas Royalty Suit. EOTT was served on November 9, 1995 with a
petition styled The State of Texas, et al. vs. Amerada Hess Corporation, et al.
The matter was filed in District Court in Lee County, Texas and involves several
major and independent oil companies and marketers as defendants. The plaintiffs
are attempting to put together a class action lawsuit alleging that the
defendants acted in concert to buy oil owned by members of the plaintiff class
in Lee County, Texas, and elsewhere in Texas, at "posted" prices, which the
plaintiffs allege were lower than true market prices. There is not sufficient
information in the petition to fully quantify the allegations set forth in the
petition, but the General Partner believes that any such claims against the
Partnership will prove to be without merit.

     The State of Texas, et al. vs. Amerada Hess Corporation, et al., Cause No.
97-12040; In the 53rd Judicial District Court of Travis County, Texas. This case
was filed on October 23, 1997 in Austin by the Texas Attorney General's office
and involves several major and independent oil companies and marketers as
defendants. EOTT was served on November 18, 1997. The petition states that the
State of Texas brought this action in its sovereign capacity to collect
statutory penalties recoverable under the Texas Common Purchaser Act, arising
from Defendants' alleged willful breach of statutory duties owed to royalty,
overriding royalty and working interest owners of crude oil sold to Defendants,
as well as alleged breach of Defendants' common law and contractual duties. The
Plaintiffs also allege that the Defendants have engaged in discriminatory
pricing of crude oil. This case appears to be similar to the Lee County, Texas
case filed by the State of Texas on November 9, 1995 and disclosed previously.
EOTT and several of the defendants have engaged in settlement negotiations with
the State of Texas, which, if consummated, would result in a dismissal of the
claims of the State.

     McMahon Foundation and J. Tom Poyner vs. Amerada Hess Corporation, et al.
(Including EOTT Energy Operating Limited Partnership), Civil Action No.
H-96-1155; United States District Court, Southern District of Texas, Houston
Division (Texas Federal Anti-Trust Suit). This suit was filed on April 10, 1996
as a class action complaint for violation of the federal antitrust laws and
involves several major and independent oil companies and marketers as
defendants. The relevant area is the entire continental United States, except
for Alaska, New York, Ohio, Pennsylvania, West Virginia and the Wilmington Field
at Long Beach, California. The plaintiffs claim that there is a combination and
conspiracy among the defendant oil companies to fix, depress, stabilize and
maintain at artificially low levels the price paid for the first purchase of
lease production oil sold from leases in which the class members own interests.
This was allegedly accomplished by agreement of the defendants to routinely pay
for first purchases at posted prices rather than competitive market prices and
maintain them in a range below competitive market prices through an undisclosed
scheme of using posted prices in buy/sell transactions among themselves to
create the illusion that posted prices are genuine market prices. The plaintiffs
allege violations from October of 1986 forward. No money amounts were claimed,
and it is not possible to determine any potential exposure until further
discovery is done.

     Randolph Energy, Inc., et al. vs. Amerada Hess Corporation, et al., Civil
Action No. 2:97CV273PG; In the United States District Court for the Southern
District of Mississippi, Jackson Division (Mississippi Federal Anti-Trust Suit).
EOTT received the summons in this matter on August 18, 1997. The case was filed
on August 5, 1997 and is a class action complaint for alleged violation of the
federal antitrust laws which involves several major and independent oil
companies and marketers as defendants. The plaintiffs claim that this litigation
arises out of a combination and conspiracy of the defendant oil companies to
fix, depress, stabilize and maintain at artificially low levels the prices paid
for the first purchase of lease production oil sold from leases in which the
class members own interests. The issues appear to be a duplication of the issues
in the Texas Federal Anti-Trust Suit previously discussed. No money amounts were
claimed, and it is not possible to determine any potential exposure until
further discovery is done.

     Cameron Parish School Board, et al. vs. Texaco, Inc., et al.; Civil Action
No. C-98-111; In the United States District Court for the Western District of
Louisiana, Lake Charles Division (Louisiana Federal Anti-Trust Suit). This case
was originally filed as a state law claim in Louisiana. When the case was
removed to federal court, the anti-trust claims were added, similar to the
claims made in the Texas Federal Anti-Trust Suit and the Mississippi Federal
Anti-Trust Suit. The plaintiffs claim that this litigation arises out of a
combination and conspiracy of the defendant oil companies to fix, depress,
stabilize and maintain at artificially low levels the prices paid for the first
purchase of lease production oil sold from leases in which the class members own
interests. The issues appear to be a duplication of the issues in the Texas
Federal Anti-Trust Suit and the Mississippi Federal Anti-Trust Suit, both
previously discussed. On October 22, 1998, the judge granted the Plaintiffs'
motion to amend the petition and add additional defendants. The Partnership and
the General Partner were added to the case as defendants at that time. No money
amounts were claimed and it is not possible to determine any potential exposure
until further discovery is done.

     The Texas Federal Anti-Trust Suit, the Mississippi Federal Anti-Trust Suit
and the Louisiana Anti-Trust Suit, along with several other suits to which EOTT
is not a party, were consolidated and transferred to the Southern District of
Texas by Transfer Order dated January 14, 1998. The Judicial Panel on
Multidistrict Litigation made this recommendation due to similarity of issues in
the cases. EOTT and the General Partner, along with a number of other
defendants, have entered into a class-wide settlement with the defendants which
has been preliminarily approved by the Court. A final approval hearing on the
class-wide settlement is scheduled for April 5, 1999.

     Mobil Oil Corporation vs. EOTT Energy Operating Limited Partnership and
EOTT Energy Corporation, Cause No. CV98-04881, M-298th Judicial District Court,
Dallas County, Texas (Mobil Suit). This suit was filed on June 25, 1998 against
both EOTT and the General Partner. Mobil alleged that it overpaid EOTT in
connection with a crude oil contract between the parties. EOTT claimed that it
was entitled to offsets to the overpayment alleged by Mobil and tendered the
amount EOTT believed it owed. The case was settled in November of 1998, with
EOTT tendering cash and services to resolve the matter.

     Assessment for Crude Oil Production Tax from the Comptroller of Public
Accounts, State of Texas. The Partnership received a letter from the
Comptroller's Office dated October 9, 1998 assessing the Partnership for
severance taxes the Comptroller's Office alleges are due on a difference the
Comptroller's Office believes exists between the market value of crude oil and
the value reported on the Partnership's crude oil tax report for the period of
September 1, 1994 through December 31, 1997. The letter states that the action,
based on a desk audit of the Partnership's crude oil production reports, is
partly to preserve the statute of limitations where crude oil severance tax may
not have been paid on the true market price of the crude oil. The letter further
states that the Comptroller's position is similar to claims made in several
lawsuits, including the Texas Federal Anti-Trust Suit, in which the Partnership
is a defendant. The amount of the assessment, including penalty and interest, is
approximately $1.1 million. While the claim is still being reviewed, the General
Partner believes the Partnership should be without liability in this or related
matters.

      General Matters. EOTT believes that it has obtained or has applied for all
of the necessary permits required by federal, state, and local environmental
agencies for the operation of its business. Further, the Partnership believes
that there are no outstanding liabilities or claims relating to environmental
matters, individually and in the aggregate, which would have a material adverse
impact on the Partnership's financial position or results of operations.

17.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following disclosures on the estimated fair value of financial
instruments are presented in accordance with the requirements of SFAS No. 107,
"Disclosures About Fair Value of Financial Instruments" and SFAS No. 119,
"Disclosures About Derivative Financial Instruments and Fair Value of Financial
Instruments." Fair value as defined in SFAS No. 107 represents the amount at
which the instrument could be exchanged in a current transaction between willing
parties. The estimated fair value amounts have been determined by EOTT using
available market data and valuation methodologies. Judgment is required in
interpreting market data and the use of different market assumptions or
estimation methodologies may affect the estimated fair value amounts.

     Credit Risk. In the normal course of business, EOTT extends credit to
various companies in the energy industry. Within this industry, certain elements
of credit risk exist and may, to varying degrees, exceed amounts recognized in
the accompanying consolidated financial statements, which may be affected by
changes in economic or other external conditions and may accordingly impact
EOTT's overall exposure to credit risk. EOTT's exposure to credit loss in the
event of nonperformance is limited to the book value of the trade commitments
included in the accompanying Consolidated Balance Sheets. EOTT manages its
exposure to credit risk through credit analysis, credit approvals, credit limits
and monitoring procedures. Further, the General

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Partner believes that its portfolio of receivables is well diversified and that
the allowance for doubtful accounts is adequate to absorb any potential losses.
EOTT requires collateral in the form of letters of credit for certain of its
receivables.

     Market Risk. EOTT trading and non-trading transactions give rise to market
risk, which represents the potential loss that can be caused by a change in the
market value of a particular commitment. EOTT closely monitors and manages its
exposure to market risk to ensure compliance with EOTT's stated risk management
policies which are regularly assessed to ensure their appropriateness given
EOTT's objectives, strategies and current market conditions.

     The following table presents the carrying amounts and estimated fair values
of the Partnership's financial instruments at December 31, 1998 and 1997 (in
millions):

</TABLE>


     The following methods and assumptions were used to estimate the fair value
of financial instruments:

     Cash and cash equivalents, short-term borrowings, note payable, bridge
loan, term loan and repurchase agreements. Fair value for these current assets
and liabilities was considered to be the same as the carrying amounts because of
their liquidity and market-based interest where applicable.

     Foreign currency contracts. Quoted market prices are used in determining
the fair value of financial instruments held or issued. If quoted prices are not
available, fair values are estimated on the basis of pricing models or quoted
prices for financial instruments with similar characteristics.

     Long-term liabilities. These liabilities represent long-term borrowings on
which the carrying amounts approximate fair value because the effective annual
interest rates of these instruments reflect interest rates at December 31, 1997.

OTHER THAN TRADING ACTIVITIES

     EOTT enters into forwards, futures and other contracts to hedge the impact
of market fluctuations on assets, lease purchases or other contractual
commitments. However, EOTT does not consider its commodity futures and forward
contracts to be financial instruments since these contracts require or permit
settlement by the delivery of the underlying commodity, and thus are not subject
to the provisions of SFAS No. 119. Changes in the market


                                      F-24
<PAGE>   72


                           EOTT ENERGY PARTNERS, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


value of these transactions are deferred until the gain or loss is recognized on
the hedged transaction at which time such gains and losses are recognized
through cost of sales.

     EOTT routinely enters into foreign currency futures contracts to hedge
foreign currency exposure from commercial transactions relating to current month
crude purchases and sales as well as fixed price swaps. These contracts
generally mature in one year or less. At December 31, 1998 and 1997, foreign
currency contracts with a notional principal amount of $11.7 million and $22.9
million, respectively, were outstanding, having exchange rates which
approximated current market exchange rates.

TRADING ACTIVITIES

     Prior to 1998, EOTT offered limited price risk management products to the
energy sector which were not material to EOTT's financial position or results of
operations. These products include swap agreements which require payments to (or
receipt of payments from) counterparties based on the differential between a
fixed and variable price for the commodities specified, options and other
contractual arrangements. EOTT accounted for these activities using the
mark-to-market method of accounting and recorded the gain or loss as a cost of
sales in the period of the change in the market with an offsetting entry to
trade accounts receivable or payable as appropriate. In connection with the
realignment initiatives discussed in Note 5, EOTT ceased providing price risk
management products to its customers.

18.  NEW ACCOUNTING STANDARDS

     SFAS No. 130, "Comprehensive Income" requires the presentation of
comprehensive income which is traditional net income (loss) adjusted for certain
items that previously were only reflected as direct charges or credits to
equity. EOTT adopted SFAS No. 130 in the first quarter of 1998. For the years
ended December 31, 1998, 1997 and 1996 traditional net income (loss) and
comprehensive income (loss) are the same.

     SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
Information" requires that segment reporting for public companies be measured
the same way management identifies and evaluates information internally. EOTT
adopted SFAS No. 131 for year end 1998 reporting and restated prior year
information based on the following reportable business segments - North American
Crude Oil - East of Rockies, Pipeline Operations and West Coast Operations. See
Note 19.

     In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use", which establishes
new accounting and reporting standards for the costs of computer software
developed or obtained for internal use. The statement requires companies to
capitalize certain costs that are incurred in developing or designing computer
software. This statement is effective for financial statements beginning after
December 15, 1998. The impact of this new standard will not have a significant
effect on EOTT's financial position or results of operations.

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". The Statement
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. The Statement requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


designate, and assess the effectiveness of transactions that receive hedge
accounting. SFAS No. 133 is effective for fiscal years beginning after June 15,
1999. The standard cannot be applied retroactively but early adoption is
permitted. EOTT has not yet determined the impact of adopting SFAS No. 133;
however, this standard could increase volatility in earnings and partners'
capital, through other comprehensive income.

     In December 1998, the Emerging Issues Task Force ("EITF") reached a
consensus on Issue 98-10, "Accounting for Contracts Involved in Energy Trading
and Risk Management Activities." The Issue 98-10 is effective for fiscal years
beginning after December 15, 1998, and requires energy trading contracts (as
defined) to be recorded at fair value on the balance sheet, with the change in
fair value included in earnings. The consensus requires the effect of initial
application of Issue 98-10 to be recorded as a cumulative effect of a change in
accounting principle effective January 1, 1999, for calendar year companies.
Management has determined that the cumulative effect of the adoption of the new
accounting standard will be an increase in net income which will not be in
excess of $2.0 million.

19.  BUSINESS SEGMENT INFORMATION

     In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." This
standard requires that companies report certain information about operating
segments in complete sets of financial statements and in condensed financial
statements of interim periods for fiscal years beginning after December 15,
1997. EOTT adopted this statement for the fiscal year ending December 31, 1998.

     EOTT has changed the composition of its reportable segments and has
restated the corresponding items of segment information for earlier periods.
EOTT has three reportable segments, which management believes are necessary to
make decisions about resources to be allocated and assess its performance: North
American Crude Oil - East of Rockies, Pipeline Operations and West Coast
Operations. The North American Crude Oil - East of Rockies segment primarily
purchases, gathers, transports and markets crude oil. The Pipeline Operations
segment operates approximately 5,300 active miles of common carrier pipelines
operated in 15 states. The West Coast Operations include crude oil gathering and
marketing, refined products marketing and a natural gas liquids business.

     The accounting policies of the segments are the same as those described in
the summary of significant accounting policies as discussed in Note 2. EOTT
evaluates performance based on operating income (loss).

     EOTT accounts for intersegment revenue and transfers between North American
Crude Oil - East of Rockies and West Coast Operations as if the sales or
transfers were to third parties, that is, at current market prices. Intersegment
revenues for Pipeline Operations are based on published pipeline tariffs.

20.  SUBSEQUENT EVENTS

     On January 19, 1999, the Board of Directors of EOTT Energy Corp., as
General Partner, declared the Partnership's regular quarterly cash distribution
of $0.475 per Unit for the period October 1, 1998 through December 31, 1998. The
total distribution of approximately $6.9 million was paid on February 12, 1999
to the General Partner and all Common and Special Unitholders of record as of
the close of business on January 29, 1999. The fourth quarter distribution was
paid without using distribution support from Enron.

     On February 12, 1999, the Partnership obtained approval of proposals
presented at a Special Meeting of Unitholders. Approval of these proposals,
among other things, (a) authorized the Partnership to issue an additional 10
million Common Units to raise cash to reduce indebtedness, for acquisitions and
other Partnership purposes, (b) changed the terms of the Special Units so that
they became convertible into Common Units and (c) resulted in an increase in
Enron's distribution support to $29 million and an extension of that support
through the fourth quarter of 2001. As a result of the approval of the
proposals, Enron contributed the $21.9 million in APIs outstanding pursuant to
its commitment made in connection with the Support Agreement discussed in Note
12.

         thereafter.

         A written notice of termination under this Section 1.2 shall be given

         (b)     [*]

         (c)      APPLICABILITY. The provisions of this Section 1.3 are only
                  applicable to the Supply Volumes provisions of this Agreement.
                  For purposes of this Agreement any reference to Supply Volumes
                  provisions of this Agreement shall mean EOTT's obligation to
                  provide Supply Volumes and Koch's obligation to purchase
                  Supply Volumes.


                               ARTICLE 2 - VOLUMES

2.1      SUPPLY VOLUMES. EOTT shall deliver and sell and Koch shall take
         delivery of and purchase [*] barrels per day ("BPD"), on average in
         each month, of Domestic Sweet Crude Oil as defined in Section 2.1(a)
         subject to the Adjusted Supply Volume requirements in Section 2.1(d).
         The "SUPPLY VOLUMES" are the volumes of Domestic Sweet Crude Oil which
         EOTT agrees to sell and deliver and Koch agrees to take delivery of and
         purchase at Cushing, Oklahoma. The Supply Volumes are subject to the
         following:

         (a)      For purposes of this Agreement, "DOMESTIC SWEET CRUDE OIL"
                  means crude oil produced in the United States that (i) meets
                  all the quality specifications of this Agreement for Supply
                  Volumes; (ii) is acceptable by Arco Pipeline's (or its
                  successor in interest) Cushing terminal at the time of
                  delivery as domestic sweet 


                                       2

<PAGE>   3

                  crude oil; and (iii) is deliverable into the NYMEX's light
                  sweet crude oil future contract.

         (b)      Supply Volumes sold to Koch by EOTT shall first be satisfied
                  with crude oil delivered by EOTT to the Terminal under the
                  terms of Article 6 of this Agreement ("TERMINAL VOLUMES.")
                  Supply Volumes necessary under this Agreement in excess of the
                  Terminal Volumes shall be sold to Koch into/within Arco's
                  Cushing Terminal. However, in no event shall EOTT deliver less
                  than [*] bpd, subject to the adjustment in Section 2.1(d),
                  of Supply Volumes to Koch at the Terminal and any Terminal
                  Volume in excess of [*] bpd shall be first applied to
                  satisfy the Supply Volumes.

         (c)      The price for the Supply Volumes ("SUPPLY VOLUME PRICE") shall
                  be determined pursuant to the Supply Volume Price Formula in
                  Article 3.

         (d)      ADJUSTED SUPPLY VOLUMES. Supply Volumes sold under this
                  Agreement shall be adjusted based on the rates of
                  decline/increase for onshore production in the lower
                  forty-eight United States as such rates of decline/increase
                  are calculated from oil production volume data published by
                  the Energy Information Administration of the Department of
                  Energy in their publication entitled Petroleum Supply Annual
                  (PSA). The adjustment for rates of decline/increase shall be
                  based upon the following methodology: For each year, effective
                  on the first day of the second calendar month after which the
                  actual annual production volumes of crude oil are published in
                  the PSA, the volume sold under this Agreement shall be
                  multiplied by the Decline/Increase Factor, as defined below,
                  to equal the adjusted Supply Volumes. The adjusted Supply
                  Volumes, rounded to the nearest 100 bpd, shall be the Supply
                  Volumes sold under the Agreement until the next year's
                  adjusted Supply Volumes are implemented. "DECLINE/INCREASE
                  FACTOR" (DIF) shall mean the average of the annual volumes for
                  onshore production for the lower forty-eight United States
                  from the most recent PSA data divided by the average of the
                  annual volumes for onshore production for the lower
                  forty-eight United States from the PSA data for the year
                  previous to the most recent PSA annual data. In the event the
                  PSA is delayed in its release or ceases to be published for a
                  period of more than fifteen months following the previous
                  year's publication of the PSA, the parties will agree to an
                  annual adjustment to be effective approximately one year after
                  the previous annual adjustment.

                  at the time and point of delivery to Koch, be free and clear
                  of all liens, encumbrances, claims, royalties and taxes. EOTT
                  additionally warrants that it has the exclusive right to
                  receive payment in full for all Supply Volumes and that all
                  Supply Volumes and Terminal Volumes, as referenced in Section
                  6.1, will meet the quality specifications in Section 5.1 and
                  6.2, respectively.

         following services to EOTT:

         (a)      Koch shall provide to EOTT by the tenth (10th) day of each
                  month of this Agreement, a month end summary, showing a
                  breakdown on Terminal Volumes applied to Supply Volumes and
                  Terminal Volumes shipped to other carriers; and

         (b)      Koch will provide at its sole cost, custody transfer meter
                  measurement facilities at the Terminal that are designed,
                  operated, maintained and calibrated in accordance with
                  industry standards to measure the quantities of oil delivered
                  by EOTT for the account of Koch at the Terminal or for the
                  transfer to terminals to which Koch is directly connected at
                  the time of transfer, subject to operational and logistical
                  constraints of the Terminal. During the Term of the Agreement,
                  Koch will maintain connections with Arco and Texaco.

                  to the Arco Cushing terminal compliant with the specifications
                  in Section 5.1 for the crude oil stream delivered to Koch; as
                  compared to

         (b)      the direct associated operating costs and acquisition costs on
                  a per barrel basis to terminal and deliver a crude oil stream
                  to the Arco Cushing terminal compliant with the specifications
                  in Section 5.1 for a crude oil stream that would have met the

         so that EOTT may treat or otherwise dispose of such crude oil. EOTT
         shall notify Koch within 24 hours of receipt of notice from Koch under
         this provision as to whether EOTT will take delivery of such crude oil,
         if possible, or authorize Koch to terminal such crude oil pursuant to

                  (i)      This Agreement is terminated; or

                  (ii)     Either Party suffers a Force Majeure event affecting
                           the terminalling obligations under this Agreement, in
                           which case no Fee shall be assessed during the term
                           of the Force Majeure event.

         (b)      Koch shall send EOTT monthly invoices which set forth Fees due

         (c)      EOTT shall pay for all services that may be required by EOTT
                  in order to make deliveries pursuant to this Agreement that
                  are not to be performed by Koch, including but not limited to,
                  independent inspection and laboratory testing and costs

                  Volumes and Supply Volumes under Sections 5.3 and 6.3.

         (d)      Fee Adjustment: Beginning on January 1, 2002, and every three
                  years thereafter, the Fee shall be adjusted by a factor
                  calculated in the formula below. The calculation of the factor
                  adjustment for the Fee shall be based upon the Producer Price
                  Index Revision - Current Series ("PPI") and the National

                  formula:

                           Fee(Y) = 0.85(E(Y)-1) + 0.15(L(Y)-1) x (Fee(Y)-1)
                                    0.85(E(Y)-2) + 0.15(L(Y)-2)

                           Where:

                           Fee(Y) = Fee for the current three year period,
                           January 1 of year one through December 31 of year
                           three of such period.

                           Fee(Y)-1 = Fee for the period previous to the current
                           period.

                           E(Y)-1 = The average of all monthly values from the
                           PPI for Electric Power and Natural Gas Utilities,
                           West South Central region, Series ID #PCU4981-137,
                           for the three calendar years previous to the current
                           calendar year that are published by the BLS as of
                           December 30 of such year previous.

6.5      MEASUREMENT OF SUPPLY AND TERMINAL VOLUMES

         (a)      Koch shall measure deliveries of Terminal Volumes and Supply
                  Volumes by EOTT to Koch or transfer to a connecting terminal
                  by using approved custody transfer meters (according to API
                  standards) designed, maintained and operated in accordance
                  with industry standards. In the event such meter measurement
                  facilities are not available, measurement of the Supply and
                  Terminal Volumes shall be based on tank gauges at the
                  Terminal.


                                       15

<PAGE>   16

         (b)      EOTT may, at its expense, have a representative witness all
                  measurements of Supply and Terminal Volumes taken by Koch.

         (c)      All measurement facilities shall be in conformance with the
                  latest edition of API Recommended Practices, and all
                  measurements shall be in accordance with the latest edition of
                  the API Manual of Petroleum Measurements Standards, using net
                  barrels corrected to 60 degrees Fahrenheit. All meters shall
                  be proved at least once a month, and EOTT may have a
                  representative present during meter proving.

6.6      INDEMNITY.

         (a)      EOTT shall indemnify, defend and hold Koch, its parent or
                  parents, Affiliates, officers, agents, and employees harmless
                  from and against all claims, demands, damages, judgments,
                  causes of action, liabilities, lawsuits, costs, fees,
                  penalties (to the extent permitted by law) and expenses
                  (excluding attorney fees) for actual damages (including, but
                  not limited to property damage, disposal and/or treatment
                  costs, or failure to meet contractual obligations),
                  specifically excluding any consequential or incidental damages
                  associated with such actual damages, arising out of or in
                  connection with the timeliness of deliveries or quality of
                  Terminal Volumes delivered by EOTT which fail to comply with
                  the requirements of this Agreement.

         (b)      Koch shall indemnify, defend and hold EOTT, its parent or
                  parents, Affiliates, officers, agents, and employees harmless
                  from and against all claims, demands, damages, judgments,
                  causes of action, liabilities, lawsuits, costs, fees,
                  penalties (to the extent permitted by law) and expenses
                  (excluding attorney fees) for failure to meet contractual
                  obligations, specifically excluding any consequential or
                  incidental damages associated with such actual damages,
                  [*].


             ARTICLE 7 - DELIVERY POINT, TITLE, RISK AND MEASUREMENT

7.1      DELIVERY POINT. EOTT shall deliver Supply Volumes required to be
         delivered hereunder and Terminal Volumes, subject to the requirements
         of Sections 2.1, 2.2 and Articles 5 and 6, into/within the facilities
         of Koch at Cushing, Oklahoma, and Arco's Cushing Terminal, and/or by
         in-line transfer or as mutually agreed to between the parties at
         Texaco's Cushing terminal or Shell's Cushing terminal (or the
         respective successors in interest of these terminals). Koch shall
         deliver any Terminal Volumes in excess of Supply Volumes to a carrier
         designated by EOTT with which Koch has a direct connection and capacity
         to deliver to the desired terminal.

7.2      TITLE AND RISK. Title to and risk of loss of Supply and Terminal
         Volumes delivered hereunder shall pass at the delivery points
         contemplated by Section 7.1. EOTT shall retain 



                                       16

<PAGE>   17

         title to and risk of loss of the Terminal Volumes until delivered to
         Koch as Supply Volumes.

7.3      VARIATION IN DELIVERIES. The Parties agree that the Supply and Terminal
         Volumes shall be delivered in accordance with the applicable published
         transportation tariffs of relevant pipelines into the Terminal.
         Accordingly, the total volume delivered during each month shall be
         deemed to have been delivered on each day during the month at an
         average daily rate during that month.

7.4      MEASUREMENT OF SUPPLY AND TERMINAL VOLUMES. The quantity of Supply and
         Terminal Volumes physically delivered under this Agreement shall be
         determined by the official shipper's balance at the custody transfer
         meter at the delivery points described in Section 7.1 maintained in
         accordance with the published rules and regulations of the pipeline
         carrier or terminal operator which takes delivery of such Supply or
         Terminal Volumes at the delivery point. In the event that a Party owns
         and maintains a meter that is to be used for measurement of Supply or
         Terminal Volumes, measurement from that meter shall be conducted
         according to the API Manual of Petroleum Measurement Standards in
         effect at the time of the measurement, and the metering equipment used
         for such measurement shall be proven.

         Either party may request for a meter to be proven more than once a
         month, using the following procedure: A Party owning a meter that is to
         be proven shall give the other Party to this Agreement at least
         forty-eight hours advance written or verbal notice prior to meter
         proving, and the Party receiving such notice shall have the right to
         witness that meter proving. The Parties shall use all reasonable
         efforts to have such proving occur as soon as practicable after the
         request thereof and in any event no later than ten (10) days after such
         request. If, on any such proving, the meter factor is determined to be
         correct (varies by less than 0.25% from the last meter proving), the
         meter shall be deemed to be accurate for the purposes of this Article
         7, and no adjustment shall be made in computing the quantity of the
         Supply or Terminal Volumes delivered and the Party which requested the
         proving shall pay the expenses of the proving. If, on any such proving,
         the meter factor is determined not to be correct, the Party which did
         not request the proving shall pay the expense thereof and the quantity
         of Supply or Terminal Volumes delivered shall be adjusted for any
         period which is known definitely or agreed upon by the Parties;
         provided however that, if the period is not known definitely or agreed
         upon by the Parties, such adjustment shall be for the period covering
         the last half of the volumes measured by the meter being proven since
         the date of the last proving.

                      ARTICLE 8 - LIMITATION ON OBLIGATIONS

8.1      FORCE MAJEURE EVENTS. In the event of the occurrence of a Force Majeure
         event which prevents performance hereunder, the Party or Parties whose
         performance is thereby prevented or delayed shall, unless otherwise
         provided below, be relieved for any obligation or liability under
         Article 2 or Article 6 of this Agreement other than Koch's obligation
         to pay for Supply Volumes delivered prior to the Force Majeure event or
         EOTT's obligation to pay for terminalling services provided prior to
         the Force Majeure event. "FORCE MAJEURE" means an event which is beyond
         the reasonable control of the Parties that either prevents the Party
         from delivering the affected Supply Volumes or prevents the Party from
         accepting the delivery of the affected Supply Volumes. The following
         are the only instances that will be recognized as Force Majeure events:
         earthquakes, floods, landslides, civil disturbances, sabotage, acts of
         public enemies, war, blockages, insurrections, riots, epidemics, the
         act of any governmental, statutory or regulatory authority, the
         inability to obtain or the curtailment of electric power, water or
         fuel, strikes, lockouts or other labor disruptions, fires, and
         explosions. For greater certainty, a lack of funds, the availability of
         more attractive markets, or inefficiencies in operations do not
         constitute Force Majeure events. The Party claiming the Force Majeure
         event agrees to notify the other Party of the occurrence of the Force
         Majeure event as soon as possible, but in any event within two (2)
         Business Days, specifying the causes of and expected duration of the
         Force Majeure event.

         (a)      EXCEPTIONS. No Party shall be entitled to the benefits of the
                  provisions of this Section 8.1 under any or all of the
                  following circumstances:

                  (i)      if the failure to observe or perform any of the
                           covenants or obligations therein imposed upon it was
                           caused by arrest or restraint by any government or
                           regulatory or statutory undertaking or order of any
                           court and such arrest, restraint or order was the
                           result of breach by the Party claiming Force Majeure
                           of the terms of a permit, license, certificate or
                           other authorization granted by a governmental or
                           regulatory body having jurisdiction, or of any
                           applicable laws, regulations or orders; or

                  (ii)     if the failure to observe or perform any of the
                           covenants or obligations herein imposed upon it was
                           caused by the Party claiming Force Majeure having
                           failed to remedy the conditions and to resume the
                           performance of such covenants or obligations with
                           reasonable dispatch.

         (b)      RESUMPTION OF PERFORMANCE. Upon cessation of the causes of
                  such failure or delay by either Party, performance hereunder
                  shall be resumed. Such failure or

<PAGE>   19
 
                  delay shall not operate to extend the Term of this Agreement
                  nor obligate either Party to make up any quantities not
                  delivered or accepted. Nothing herein shall be interpreted as
                  requiring either Party to settle any strike or other labor
                  dispute contrary to what it deems its best interest or
                  requiring any Party to delay payment for Supply Volumes
                  delivered pursuant hereto.

8.2      KOCH CUSHING TERMINAL SHUTDOWN.

         (a)      KOCH CUSHING TERMINAL SHUTDOWN. If Koch makes a bona fide
                  decision to permanently terminate operations at the Terminal,
                  Koch shall forthwith give notice of such decision to EOTT (a
                  "KOCH CUSHING TERMINAL SHUTDOWN NOTICE"), including the
                  reasons therefor and the scheduled date for the permanent
                  termination of operations at Cushing (any such termination
                  referred to herein as a "KOCH CUSHING TERMINAL SHUTDOWN") and

                  (i)      Koch shall be entitled to terminate this Agreement
                           upon the date of the Koch Cushing Terminal Shutdown
                           PROVIDED THAT the shutdown does not occur until at
                           least ninety (90) days after the delivery of Koch
                           Cushing Terminal Shutdown Notice and no later than
                           one (1) year after the delivery of such notice;

                  (ii)     EOTT shall be entitled to terminate this Agreement at
                           any time after the delivery of the of Koch Cushing
                           Terminal Shutdown Notice;

                  (iii)    EOTT shall also be entitled to suspend its
                           obligations to sell and deliver Supply Volumes
                           pursuant to this Agreement by notice to Koch at any
                           time after the delivery of a Koch Cushing Terminal
                           Shutdown Notice, which suspension shall commence
                           thirty (30) days after the delivery of the suspension
                           notice by EOTT and continue until the earlier of the
                           termination of this Agreement or thirty (30) days
                           after delivery of a notice by EOTT to Koch of EOTT's
                           election to resume the sale and delivery of Supply
                           Volumes to Koch pursuant to this Agreement;

                  (iv)     EOTT, in addition to being entitled to suspend its
                           obligations to deliver and sell Supply Volumes under
                           this Agreement, shall be entitled to a right of first
                           refusal to purchase the Terminal from Koch (or any
                           successor in interest to Koch for as long as this
                           Agreement is in effect) when Koch (or any successor
                           in interest to Koch for as long as this Agreement is
                           in effect) receives any bona fide bid which Koch (or
                           any successor in interest to Koch for as long as this
                           Agreement is in effect) is willing to accept for the
                           sale of such terminal; and

                  (v)      In the event EOTT does not exercise its right of
                           first refusal on the Terminal (as referenced in
                           Section 8.2(a)(iv) above), Koch (or any successor in
                           interest) shall include, as a requirement in any sale
                           of the 



                                       19

                           Terminal, that the purchaser agree to continue with
                           this Agreement for the remainder of its Term.

8.3      ANTICIPATED MARKET CHANGES

         (a)      [*]

         (b)      If the NYMEX Light Sweet Crude Oil Contract is transacted on a
                  gravity delivered basis, Section 3.1 shall be amended to
                  incorporate the related price adjustments for a gravity
                  delivered crude oil barrel.

8.4      MARKET CHANGE ON SUPPLY VOLUMES RENDERING EOTT PERFORMANCE UNECONOMIC.

         (a)      If a change in the Crude Oil Market at Cushing, Oklahoma
                  (hereinafter referred to as a "Changed Condition") occurs and,
                  as a direct result of that change, [*], then EOTT shall be
                  entitled to renegotiate the price under which the Parties sell
                  and purchase Supply Volumes under this Agreement by written
                  notice to Koch ( the "EOTT RENEGOTIATION NOTICE"). "Economic
                  Harm" for EOTT results when an alternative publicly quoted
                  market pricing index for Domestic Sweet Crude Oil at Cushing,
                  readily obtainable at Cushing, reflects prices which are
                  greater than the price paid by Koch to EOTT for Supply Volumes
                  and priced during the same relevant time period. For purposes
                  of this Agreement, rolling the barrels by selling front/back
                  spreads does not constitute an alternative publicly quoted
                  market.

         (b)      EOTT shall not be entitled to deliver an EOTT Renegotiation
                  Notice unless EOTT shall have delivered to Koch a detailed
                  description of EOTT's calculations of EOTT's Uneconomic
                  Conditions, which shall specify the difference between the
                  market pricing provisions in section 3.1 and another publicly
                  quoted market pricing index for Domestic Sweet Crude Oil at
                  Cushing, Oklahoma, of the same quality priced during the same
                  time frame.


         (c)      Concurrent with the delivery of the EOTT Renegotiation Notice,
                  EOTT shall make a bona fide written offer to Koch, in good
                  faith, (collectively the "EOTT ADJUSTING OFFER") to amend the
                  Supply Volume Price Formula.

         (d)      Koch shall be entitled to

                  (i)      accept any EOTT Adjusting Offer at any time within
                           the thirty (30) days after the delivery thereof; or

                  (ii)     terminate the Supply Volumes provisions of this
                           Agreement by 30 day written notice to EOTT at any
                           time after the delivery of an EOTT Renegotiation
                           Notice, which shall trigger Koch's Right of First
                           Refusal in Schedule C.

8.5      MARKET CHANGE ON SUPPLY VOLUMES RENDERING KOCH PERFORMANCE UNECONOMIC.

         (a)      If a Changed Condition occurs and, as a direct result of that
                  change,  [*], then Koch shall be entitled to renegotiate the
                  price under which the Parties to sell and purchase Supply
                  Volumes under this Agreement by written notice to EOTT (the
                  "KOCH RENEGOTIATION NOTICE"). "Economic Harm" for Koch results
                  when an alternative publicly quoted market pricing index for
                  Domestic Sweet Crude Oil at Cushing, readily obtainable at
                  Cushing, reflects prices which are less than the price paid by
                  Koch to EOTT for Supply Volumes and priced during the same
                  relevant time period. For purposes of this Agreement, rolling
                  the barrels by selling front/back spreads does not constitute
                  an alternative publicly quoted market.

         (b)      Koch shall not be entitled to deliver a Koch Renegotiation
                  Notice unless Koch shall have delivered to EOTT a detailed
                  description of Koch's calculations of Koch's Uneconomic
                  Conditions, which shall specify the difference between the
                  market pricing provisions in section 3.1 and another publicly
                  quoted market pricing index for Domestic Sweet Crude Oil at
                  Cushing, Oklahoma, of the same quality priced during the same
                  time frame.

         (c)      Concurrent with the delivery of the Koch Renegotiation Notice,
                  Koch shall make a bona fide written offer to EOTT, in good
                  faith, (collectively the "KOCH ADJUSTING OFFER") to amend the
                  Supply Volume Price Formula.

         (d)      EOTT shall be entitled to

                  (i)      accept any Koch Adjusting Offer at any time within
                           the thirty (30) days after the delivery thereof; or

                  (ii)     terminate the Supply Volumes provisions of this
                           Agreement by 30 day written notice to Koch at any
                           time after the delivery of a Koch Renegotiation
                           Notice.

         (e)      In the event EOTT rejects any Koch Adjusting Offer, EOTT may
                  enter into agreements with third parties on all or a portion
                  of the Supply Volumes, for terms in total which shall not
                  exceed six (6) months from the date on which Koch ceases
                  purchasing Supply Volumes. At any time Koch may elect,
                  effective no sooner than six (6) months after the date on
                  which Koch ceases purchasing Supply Volumes, to purchase crude
                  oil under its Right of First Refusal, as set out in Schedule
                  C.

8.6      CHANGES ON TERMINAL VOLUMES RENDERING KOCH PERFORMANCE UNECONOMIC. The
         term "KOCH" for purposes of this Section 8.6 shall mean Koch or its
         successors in interest approved in writing by EOTT.

         (a)      If:

                  (i)      [*]

                  (ii)     [*]

                  (herein referred to as the "UNECONOMIC TERMINAL CONDITIONS");
                  then Koch shall be entitled to suspend the obligations of the
                  Parties to deliver and terminal Terminal Volumes and sell and
                  purchase Supply Volumes under this Agreement by written notice
                  to EOTT (the "TERMINAL SUSPENSION NOTICE"). Such suspension of
                  obligations shall continue until the earlier of:


                                       22

<PAGE>   23
  
                           (A)      Thirty (30) days after the delivery of a
                                    notice by Koch to EOTT that the Uneconomic
                                    Terminal Conditions have ceased (the "KOCH
                                    RESUMPTION NOTICE"); or

                           (B)      The Termination of this Agreement.

         (b)      Koch shall not be entitled to deliver a Terminal Suspension
                  Notice unless Koch shall have delivered to EOTT a full
                  explanation of the Uneconomic Terminal Conditions, including a
                  detailed description of Koch's calculations of its direct
                  terminal costs.

         (c)      Concurrent with the delivery of the Terminal Suspension
                  Notice, Koch shall make a bona fide written offer to EOTT (the
                  "ADJUSTING TERMINAL OFFER") to amend the Fee.

         (d)      EOTT shall be entitled to accept or reject any Adjusting
                  Terminal Offer at any time within the thirty (30) days after
                  the delivery thereof.

         (e)      In the event EOTT rejects an Adjusting Terminal Offer, Koch
                  shall have the right to either continue the Agreement using
                  the Fee currently in place, issue to EOTT a Koch Cushing
                  Terminal Shutdown Notice, as set out in Section 8.2(a), or
                  continue terminalling for volumes reasonably adjusted using
                  the remaining unaffected assets at the Terminal which are
                  dedicated to EOTT pursuant to the Agreement.

         (f)      DEFINITION - TERMINAL CHANGE. "TERMINAL CHANGE" means a change
                  in conditions which causes or is projected to cause Koch to
                  incur extraordinary costs at the Terminal. Such causes shall
                  include, but are not limited to:

                  (i)      A change in the law (including but not limited to any
                           federal, state or local level statutes, regulations,
                           ordinances, orders and other legal requirements); or

                  (ii)     A change in industry practices (including but not
                           limited to operational changes and specifications);
                           or

                  (iii)    Physical damage to the Terminal resulting from
                           causes, whether occurring naturally or by other
                           means, which include, but are not limited, to any
                           weather conditions, electrical conditions,
                           explosions, fires and abnormal operational
                           occurrences. Provided, however, that EOTT shall be
                           allowed, at its sole discretion, to carry insurance
                           on the Terminal assets dedicated to EOTT, to protect
                           its position under this Agreement with Koch as an
                           additional insured so that such insurance proceeds
                           are paid to Koch and applied against Koch's Cash
                           Costs and or Terminal Changes in Section 8.6(a). If
                           any non-Koch entity successor or assign to this
                           Agreement receives insurance proceeds for damage to
                           the assets dedicated to EOTT, 



                                       23

<PAGE>   24

                           such proceeds shall be applied to offset Koch's Cash
                           Costs or Terminal Changes.

                  The foregoing notwithstanding, "Terminal Change" shall not
                  include costs which exceed costs necessary to (a) repair
                  damage to the Terminal, or (b) keep the Terminal in compliance
                  with law or industry practices.

8.7      SUPPLY VOLUMES SALES DURING FORCE MAJEURE EVENTS AND TERMINAL VOLUMES
         SUSPENSIONS. Any Supply Volumes which are not sold and delivered to
         Koch under this Agreement due to any Force Majeure event or Terminal
         Volumes Suspension pursuant to Section 8.6 may be sold by EOTT to any
         other Person free and clear of all rights or claims of Koch under this
         Agreement.

                           EOTT in finding substitute purchasers of the Supply
                           Volumes;

                  (ii)     any loss of profit by EOTT as measured by the
                           proceeds which EOTT would have received from the sale
                           of Supply Volumes to Koch under this Agreement at the
                           Supply Volume Price, less the proceeds received by
                           EOTT on the sale of such Supply Volumes to the
                           substitute purchaser. In calculating the costs under
                           this item (ii), EOTT shall be required to include all
                           direct costs associated with such sale; and

                           Applicable Law.

         (b)      EOTT's liability for any breach of its obligations to sell and
                  deliver Supply Volumes to Koch in the volumes required under
                  this Agreement shall be limited to:

                  (i)      all reasonable direct costs and expenses incurred by
                           Koch in finding substitute crude oil for the Supply
                           Volumes;

                  (ii)     any loss in profits by Koch as measured by the
                           profits which Koch would have earned on the marketing
                           and sale of the Supply Volumes, less the profits
                           which Koch earns on the marketing and sale of
                           substitute crude oil. In calculating the costs under
                           this item (ii), Koch shall be required to include all
                           of the types of direct costs which are included in
                           the definition of Koch Cash Costs; and

                  (iii)    interest as may be payable under this Agreement or
                           Applicable Law.

         (c)      Except as expressly provided in Sections 9.5(a) and (b), in no
                  event, whether in tort, negligence, breach of contract,
                  warranty, indemnity, strict liability or otherwise, shall any
                  Party hereto be liable to any other Party for loss of profits,
                  revenues, use, production or contracts, downtime costs or
                  claims of customers of a Party for such damages or for any
                  financial or economic loss or for any indirect, 



                                       27

                  consequential, punitive or exemplary damages whatsoever that
                  may be suffered by any other Party. Neither party shall be
                  liable to the other for court costs, attorneys fees or other
                  litigation related costs.

         (d)      Nothing in this Section 9.5 shall have the effect of limiting
                  or reducing the obligations of any Party to mitigate its
                  losses as a result of any breach by any other Party of their
                  obligations under this Agreement and losses contemplated by
                  Sections 9.5(a) and (b) shall be calculated after giving
                  effect to the results of such mitigation or required
                  mitigation. In addition, no Party shall be entitled to recover
                  losses in respect of transactions with Affiliates unless such
                  transactions are bona fide and on terms which are more
                  favorable to the Party than the terms which would have been
                  received by the Party in the most favorable alternative arms
                  length transaction.

         (b)      A Party may at any time, without the consent of the other
                  Party, assign its interest in this Agreement to any Affiliate,
                  provided that such Affiliate shall execute and deliver to the
                  other Parties a written agreement agreeing to be bound by the
                  terms and conditions of this Agreement. Notwithstanding any
                  such assignment, the Party making such assignment shall not,
                  without the consent of the other Party (which consent shall
                  not be unreasonably withheld), be released from the

                  shall execute an appropriate consent to such assignment in a
                  form requested by the assigning Party acting reasonably. Each
                  Party agrees that the assigning Party shall remain liable to
                  the non-assigning Party notwithstanding such assignment and
                  that the Secured Party shall not be deemed to assume the

                           disclosure becomes generally available to the public
                           through no fault of the recipient Party;

                           of confidentiality; and

                  (iii)    which at any time is authorized by a Party in writing
                           to be disclosed to a specified third party.

                           underwriter or financial institution which will or
                           may provide financing to such Party;

                  (ii)     to the extent necessary to acknowledge to third
                           parties that an agreement as to the Supply and

                           regulatory body having jurisdiction; or

                  (iv)     to the extent necessary in any legal proceedings
                           between EOTT and Koch with respect to this Agreement
                           or the transactions contemplated hereby.

         (d)      Each party shall use the same reasonable efforts to keep the
                  terms of this Agreement confidential as that party uses to

         (4) years after the end of the Term. In addition, termination of this

         failure of a Party to insist upon the strict performance of any
         provision of this Agreement or to exercise any right, power or remedy
         granted hereunder shall not operate as or be construed as a waiver of
         any such provisions, right, power or remedy, or in any manner impair

         power or remedy at any subsequent time or times.

omitted in the absence of gross negligence or willful misconduct, shall not
create for the Lender any resulting liability to the Borrower.

         3.04 Letter of Credit Increased Costs. If at any time any Letter of
Credit Issuer charges the Lender amounts for a Letter of Credit greater than the

other amounts paid or payable to or on behalf of the Lender pursuant to the
preceding sentence and this sentence, shall equal such Taxes indemnified against

reasonable discretion. For purposes of this Section 6.02, the term "Lender"

payments made or required to be made hereunder, under the Note or other Credit

respect of all or any portion of or any interest in any such agreement or
document, of any nature whatsoever that are levied, imposed or asserted to be
due by any jurisdiction or by any political subdivision or taxing authority
thereof or therein and paid by the Lender, but excluding from the provisions of
this sentence any tax imposed on or measured by the net income of the Lender
pursuant to the laws of its Home Jurisdiction. If any such Taxes are paid by the
Lender, the Borrower will pay the Lender the full amount of such Taxes, and such
additional amounts as may be necessary so that the amount received pursuant to

withholding taxes and taxes imposed on or measured by net income) incurred as a
result of the receipt or accrual of the amounts payable pursuant to this
sentence under the laws of all such jurisdictions and political subdivisions and
taxing authorities (including the Lender's Home Jurisdiction), shall equal the
amount of such Taxes paid by the Lender, together with interest thereon at the
overdue interest rate provided in Section 2.06(c). The Lender agrees that it
shall notify the Borrower of any notice of deficiency, proposed adjustment or
other written claim by a taxing authority with respect to a Tax for which the
Borrower is obligated to indemnify the Lender pursuant to this Section 6.02(b);
provided, however, that the Lender's failure to provide such notice shall in no
way affect the obligation of the Borrower to indemnify the Lender pursuant to
this Section 6.02. Payments by the Borrower pursuant to this indemnification
shall be made within 30 days from the date the Lender makes written demand
therefor, which demand shall be accompanied by a certificate describing in
reasonable detail the basis thereof.

         (c) The Borrower will furnish to the Lender within 30 days after the
date the payment of any Taxes, or any withholding or deduction on account
thereof, is due pursuant to applicable law certified copies of tax receipts, or
other evidence of payment sufficient to establish a deduction or foreign tax
credit with respect to such Taxes for the applicable Lender, evidencing such
payment by the Borrower.

         SECTION 12.  MISCELLANEOUS.

         12.01 Payment of Expenses. Etc. The Borrower agrees: (i) whether or not
the transactions herein contemplated are consummated, to pay all reasonable
out-of-pocket costs and expenses (a) of the Lender in connection with the
negotiation, preparation, execution and delivery of this Agreement and the other
Credit Documents and the documents and instruments referred to herein and
therein and any amendment, waiver or consent relating hereto and thereto
(including, without limitation, the reasonable fees and disbursements of Vinson
& Elkins, L.L.P. and any local counsel) and (b) of the Lender and each of the
Lender in connection with the enforcement or preservation of the Credit
Documents and the documents and instruments referred to therein (including,
without limitation, the reasonable fees and disbursements of counsel and the
allocated cost of in-house counsel for the Lender); (ii) to pay and hold the
Lender harmless from and against any and all present and future stamp and other
similar taxes with respect to the foregoing matters and save the harmless from
and against any and all liabilities with respect to or resulting from any delay
or omission (other than to the extent attributable to the Lender) to pay such
taxes; and (iii) to indemnify the Lender, its respective officers, directors,
employees, representatives and agents (each, an "indemnified person") from and
hold each of them harmless against any and all losses, liabilities, claims,
damages or expenses reasonably incurred by any of them as a result of, or
arising out of, or in any way related to, or by reason of, regardless of when
such indemnified matter arises, (a) any investigation, litigation or other
proceeding (whether or not the Lender is a party thereto) related to the
entering into and/or performance of any Credit Document or the use of the
proceeds of any Loans or Letter of Credit hereunder, (b) (i) the actual or
alleged presence, generation or Release of Hazardous Materials on or from, or
the transportation of Hazardous Materials to or from, any Company Property or
Use Property, (ii) the non-compliance of any such Company Property or Use
Property with applicable Environmental Laws, (iii) any Release of Hazardous
Materials owned, in the possession of, or controlled by the Borrower, or (iv)
any Environmental Claim with respect to the Borrower or any of its Subsidiaries
or any Company Property or Use Property, in each case including, without
limitation, the reasonable fees and disbursements of counsel and the allocated
cost of in-house counsel and other consultants incurred in connection with any
such investigation, litigation, Environmental Claim or any of the Borrower's
acts, omissions, business, operations, or Company Property or Use Property or
other proceeding (but excluding any such losses, liabilities, claims, damages or
expenses to the extent incurred by reason of the gross negligence or willful
misconduct of the indemnified person) or (c) any settlement entered into in
connection with the foregoing to the extent such settlement has been consented
to by the Borrower, which consent shall not be unreasonably withheld. The Lender
agrees to give notice to the Borrower of any litigation or other proceeding
giving rise to an obligation of the Borrower to indemnify the Lender pursuant to
this Section 12.01, although the failure to give any such notice shall not
release or diminish any of the Borrower's obligations pursuant to this Section
12.01. To the extent that the undertaking to indemnify and hold harmless set
forth in this Section 12.01 may be unenforceable 


                                       42
<PAGE>   48


because it is violative of any law or public policy as determined by a final
judgment of a court of competent jurisdiction, the Borrower shall make the
maximum contribution to the payment and satisfaction of each of the liabilities
giving rise to claims under the indemnification provisions of this Section 12.01
which is permissible under applicable law.

         12.02 Right of Setoff. In addition to any rights now or hereafter
granted under applicable law or otherwise, and not by way of limitation of any
such rights, upon the occurrence of an Event of Default, the Lender is hereby
authorized at any time or from time to time, without presentment, demand,
protest or other notice of any kind to the Borrower or to any other Person, any
such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by the Lender(including, without limitation, by
Subsidiaries and Affiliates of the Lender) to or for the credit or the account
of the Borrower against and on account of the Obligations and liabilities of the
Borrower to the Lender under any of the Credit Documents, and all other claims
of any nature or description arising out of or connected with this Agreement or
any other Credit Document, irrespective of whether or not the Lender shall have
made any demand hereunder and although said Obligations, liabilities or claims,
or any of them, shall be contingent or unmatured. The Lender agrees to give
notice to the Borrower of any such setoff, although the failure to give any such
notice shall not diminish any of the Lender's rights pursuant to this Section
12.02.

         12.03 Notices. Except as otherwise expressly provided herein, all
notices and other communications provided for hereunder shall be in writing and
mailed, telegraphed, telexed, sent by facsimile, cabled or delivered, if to the
Borrower at the address specified opposite its signature below; if to the
Lender, at its Notice Office; or, at such other address as shall be designated
by any party in a written notice to the other parties hereto. All such notices
and communications shall be mailed, telegraphed, telexed, sent by facsimile, or
cabled or sent by overnight courier, and shall be effective when received.

         12.04 Benefit of Agreement' Assignment or Transfer. This Agreement
shall be binding upon and inure to the benefit of and be enforceable by the
respective successors and assigns of the parties hereto; provided that the
Borrower may not assign or transfer any of its rights or obligations hereunder
without the prior written consent of the Lender. The Lender may assign or
transfer any of its rights or obligations hereunder without the consent of the
Borrower

         12.05 No Waiver; Remedies Cumulative. No failure or delay on the part
of the Lender in exercising any right, power or privilege hereunder or under any
other Credit Document and no course of dealing between the Borrower and the
Lender shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights and remedies
herein expressly provided are cumulative and not exclusive of any rights or
remedies that the Lender would otherwise have. No notice to or demand on the
Borrower in any case shall entitle the Borrower to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the Lender to any other or further action in any circumstances without notice
or demand.

         12.06 Calculations; Computations. (a) The financial statements to be

with GAAP consistently applied throughout the periods involved (except as set
forth in the notes thereto or as otherwise disclosed in writing by the Borrower
to the Lender); provided, however, that, except as otherwise specifically
provided herein, all computations determining compliance with Section 10 shall
utilize accounting principles and policies in conformity with those used to
prepare the historical financial statements delivered to the Lender pursuant to
Section 8.05 of the Credit Agreement.

         (b) All computations of interest and Fees hereunder shall be made on
the basis of a year of 360 days (365 days in the case of Base Rate Loans) for
the actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest or Fees are payable.

         12.07 Interest.  It is the intention of the parties hereto that the
Lender shall conform strictly to usury laws applicable to it. Accordingly, if
the transactions contemplated hereby would be usurious as to the Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to the Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (I) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by the Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by the Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by the Lender to the
Borrower); and (ii) in the event that the maturity of the Notes is accelerated
by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to the Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by the Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be
credited by the Lender on the principal amount of the Indebtedness (or, to the
extent that the principal amount of the Indebtedness shall have been or would
thereby be paid in full, refunded by the Lender to the Borrower). All sums paid
or agreed to be paid to the Lender for the use, forbearance or detention of sums
due hereunder shall, to the extent permitted by law applicable to the Lender, be
amortized, prorated, allocated and spread throughout the stated term of the
Loans evidenced by the Notes until payment in full so that the rate or amount of
interest on account of any Loans hereunder does not exceed the maximum amount
allowed by such applicable law. If at any time and from time to time (I) the
amount of interest payable to the Lender on any date shall be computed at the
Highest Lawful Rate applicable to the Lender pursuant to this Section 12.07 and
(ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to the Lender would be less than the amount of
interest payable to the Lender computed at the Highest Lawful Rate applicable to
the Lender, then the amount of interest payable to the Lender in respect of such
subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to the Lender until the total amount of interest
payable to the Lender shall equal

<PAGE>   50


the total amount of interest which would have been payable to the Lender if the
total amount of interest had been computed without giving effect to this Section
12.07. To the extent that Article 5069-1D.003 of the Finance Code is relevant
for the purpose of determining the Highest Lawful Rate, the Lender elects to
determine the applicable rate ceiling under such Chapter by the indicated weekly
rate ceiling form time to time in effect.

8.24 Compliance With Environmental Laws


(i)

      (1) Paramount Refinery and Lakewood Tank Farm

          Environmental conditions exist in the area of the refinery and
          associated tank farm, including soil and groundwater contamination,
          that are the subject of ongoing, long-term remediation. Additionally,
          environmental issues include refinery compliance with both federal and
          state air regulations. These site conditions have been well documented
          in the following reports:

         (a) 1990 Pilko & Associates Environmental Sire Assessment.

         (b) February 1994 CET Environmental Services Revised Estimated
             Remediation Report.

         (c) 1993 Chemical Waste Management, Inc. semi-annual refinery
             groundwater monitoring report.

         (d) January 1994 Radian Corporation Report for refinery air compliance.

         (e) The Prospectus dated March 18, 1994, relating to EOTT Energy
             Partners, L.P.


      (2) 3-B Rattlesnake Refinery (Wickett, TX):

          Environmental condition may exist in the area of the refinery
          including soil and groundwater contamination. Additionally,
          environmental issues include refinery compliance with both federal and
          state solid wastes disposal regulations, including failure to report
          unscheduled releases, and possible OSHA asbestos removal violations.
          These site conditions have been documented in the following reports:

         (a) 1990 Esmond Engineering, Inc. Environmental Assessment Report.

         (b) January 13, 1992, Texas Water Commission facility inspection.

         (c) May 15,1992, U.S. Environmental Protection Agency, Region 6 search
             warrant and subsequent inspection.

         (a) The environmental issues as described in the Prospectus dated March
             18, 1994, relating to EOTT Energy Partners, L.P.


(ii)     See Schedule 5.11, Purchase & Sale Agreement by and between Koch Oil
         Company and Eott Energy Operating Limited Partnership.

(iii)    None.

(iv)     See 8.24 (a) (i) above.  In addition:

         (1)  The Oil Pollution Act of 1990 (OPA) requires owners and operators
              of "offshore facilities" to establish $150 million in financial
              responsibility to cover environmental cleanup and restoration
              costs that may be incurred in connection with an oil spill. On
              August 25, 1993, the MMS published an advanced notice of its
              intention to adopt a rule under "OPA" that would define "offshore
              facilities" to include all oil and gas facilities that have the
              potential to affect the "waters of the United States". Since EOTT
              owns and operates many pipelines and tank batteries that could be
              the source of a spill affecting the "waters of the United
              States," EOTT could become subject to the financial
              responsibility rule if it is adopted as proposed.

         (2)  All of those matters described in the Prospectus dated March 18,
              1994, relating to EOTT Energy Partners, L.P.

                                                       property. Land treatment locations at the site consist of two plots, both
                                                       approximately 40'x40' in area. Cleanup activities being conducted under

                                                       expected to require approximately one more year to complete. At such time as

         KPL        Bushton Station                    Early in 1997 excavation for construction purposes was being performed around
                                                       pumps and pipes. Crude oil contaminated soil was noted. No release
                                                       mechanism nor release quantity was identified. The soil was excavated and is
                                                       currently being landfarmed next to the excavation. Kansas AST, UST and
                                                       Hazardous Waste regulations do not explicitly define cleanup and
                                                       notification requirements for this type of situation. Kansas defers to
                                                       federal regulation (40 CFR 302.4) for reportable quantities, but it is
                                                       unlikely these would apply in this case (1000 lb. threshhold for benzene.
                                                       According to Tom Wynn of KDHC on December 1, 1997, KDHE often uses the
                                                       guidance it developed for UST cleanups to apply to hydrocarbon cleanups
                                                       generally around the state, independent of leak source. There appear to be
                                                       several elective choices when choosing a compliance path for non-UST
                                                       hydrocarbon remedial action in Kansas. If it is a small quantity, no
                                                       notification requirements exist. If relations with KDHE are important for
                                                       the facility for other reasons, it may be advantageous to notify KDHE of the
                                                       activity, and in this case, KDHE may not suggest the UST guidance should be
                                                       met. 

                                                       Testing for TPH has been conducted. When complete, soil will be put back into
                                                       the excavation. There have been no communications with the State regarding 
                                                       this issue. Standard construction practices (i.e., no hazardous waste PPE) 
                                                       were used for the excavation and land farming.

         KPL        Ponca City PL Station              Facility has one or more remedial action projects under way. The Site is a 
                                                       groundwater contamination location with leaded gasoline and some crude in

                                                       RCRA landfill operated by Conoco. The remedial action at this Site consists
                                                       of Pump and Treat to provide hydraulic containment of the contaminated
                                                       groundwater. The remedial action is proceeding under an agreement between
                                                       Koch and the OCC. In addition to operation of a pump and treat remedial
                                                       system, Koch is performing quarterly groundwater monitoring. Contamination
                                                       on the site is persistent and remediation is expected to be ongoing for
                                                       many years. Koch had evaluated more aggressive remediation options but cost
                                                       savings were limited and the OCC was not supportive in a modified remedial
                                                       approach for this site. Groundwater is being treated in a low profile air
                                                       stripper system.  Treated groundwater is reinjected through a french Drain.
                                                       The OCC documented that reinjection system did not require a UIC permit.
                                                       No current compliance concerns were identified. Future compliance

KOC       Ten Section Tank Farm                   Koch purchased the 160 acre site from Shell Western

                                                  Resources in 1991. Koch is currently using
                                                  approximately five acres for crude storage, pumping, and
                                                  transfer. The remainder of the site is either unoccupied or
                                                  used by Kern Oil and McFarland Energy for gas and crude
                                                  production. There is evidence of abandoned industrial
                                                  activity concrete footings, pits or land depressions, etc. in
                                                  various locations throughout the 160 acre site. In addition,
                                                  the Site Restoration efforts under 23 CCR are being
                                                  required by the Central Valley RWQCB of Shell, which
                                                  acts under the terms of the 1991 transaction agreement to
                                                  meet applicable state requirements for closure of
                                                  subsurface contamination issues. Koch is currently notified
                                                  at 1 year intervals of program milestones, as are PG&E,
                                                  SoCalGas, and Monterey Resources. The property transfer
                                                  agreement does not allow direct control of restoration
                                                  activities conducted by Shell.
                                                  Nature of risks:
                                                  1) that current contractor to Shell could perform activities
                                                  on Koch property not in compliance with 26CCR
                                                  regulations (e.g., management of water and soil residuals),
                                                  for which Koch, as current property owner, could be held
                                                  initially responsible if cited); and
                                                  2) that pace of restoration is not adequate to achieve
                                                  closure by the end of the period of responsibility of the
                                                  previous owner (ten years following 1991 transaction),
                                                  leading to Koch assumption of remaining issues with the
                                                  CVRWQCB.

KOC       Paloma Blend Facility                   In 1991, an inspector from the RWQCB required that the
                                                  facility prepare an SPCC plan and develop an aboveground
                                                  tank monitoring program as required by the Aboveground
                                                  Petroleum Storage Tank regulations. The SPCC plan was
                                                  developed and submitted to the RWQCB however no 
                                                  conclusion was ever reached on a tank monitoring program
                                                  as indicated in the correspondences between Koch and the
                                                  RWQCB over a one year period. According to Koch
                                                  personnel, the RWQCB ran out of funds for the program
                                                  and never followed up on.

                                                      because area manager is not aware of an inspection in the

  KPL            Tussy Station (Cherokee P/L)         The floating roof seals on Tanks 41004 and 41003 are
                                                      damaged. Emission calculations used for annual emission
                                                      inventory and for Title V applicability determination were
                                                      based on EPA tanks2 software assuming that seals are in
                                                      good condition. Thus, calculated emissions are
                                                      underestimated. Note that seals were visually inspected

                                                       property. Land treatment locations at the site consist of two plots, both
                                                       approximately 40' x 40' in area. Cleanup activities being conducted under
                                                       oversight of the OCC. Landfarming has been ongoing for one year and is
                                                       expected to require approximately one more year to complete. At such time as
                                                       remediation is complete, approval for closure of the land will be obtained
                                                       from OCC. Remediation is being conducted under approval of OCC. No compliance
                                                       issues were identified at this time.

         KPL           Bushton Station                 Early in 1997 excavation for construction purposes was being performed around
                                                       pumps and pipes. Crude oil contaminated soil was noted. No release mechanism
                                                       nor release quantity was identified. The soil was excavated and is currently
                                                       being landfarmed next to the excavation. Kansas AST, UST and Hazardous Waste
                                                       regulations do not explicitly define cleanup and notification requirements
                                                       for this type of situation. Kansas defers to federal regulation (40 CFR
                                                       302.4) for reportable quantities, but it is unlikely these would apply in
                                                       this case (1000 lb. thresh hold for benzene. According to Tom Wynn of KDHC on
                                                       December 1, 1997, KDHE often uses the  guidance it developed for UST cleanups
                                                       to apply to hydrocarbon cleanups generally around the state, independent of
                                                       leak source. There appear to be several elective choices when choosing a
                                                       compliance path for non-UST hydrocarbon remedial action in Kansas. If it is a
                                                       small quantity, no notification requirements exist. If relations with KDHE
                                                       are important for the facility for other reasons, it may be advantageous to
                                                       notify KDHE of the activity, and in this case, KDHE may not suggest the UST
                                                       guidance should be met. Testing for TPH has been conducted. When complete,
                                                       soil will be put back into the excavation. There have  been no communications
                                                       with the State regarding this issue. Standard construction practices (i.e.,
                                                       no hazardous waste PPE) were used for the excavation and land farming.

         KPL           Ponca City PL Station          Facility has one or more remedial action projects under way. The Site is a 
                                                      groundwater contamination location with leaded gasoline and some crude in the
                                                      groundwater. Contamination has migrated off the Koch property beneath a RCRA
                                                      landfill operated by Conoco. The remedial action at this Site consists of
                                                      Pump and Treat to provide hydraulic containment of the contaminated
                                                      groundwater. The remedial station is proceeding under an agreement between
                                                      Koch and the OCC. In addition to operation of a pump and treat remedial
                                                      system, Koch is performing quarterly groundwater monitoring. Contamination on
                                                      the site is persistent and remediation is expected to be ongoing for many
                                                      years. Koch had evaluated more aggressive remediation options but cost
                                                      savings were limited and the OCC was not supportive in a modified remedial
                                                      approach for this site. Groundwater is being treated in a low profile air
                                                      stripper system. Treated groundwater is reinjected through a drench Drain.
                                                      The OCC documented that reinjection system did not require a FIC permit. No
                                                      current compliance concerns were identified. Future compliance

         SECURITY AGREEMENT, dated as of December 1, 1998 between EOTT ENERGY

                              W I T N E S S E T H :

         WHEREAS, Debtor desires to incur Loans and request the issuance of
Letters of Credit and Guarantees under that certain Amended and Restated Credit
Agreement dated as of December 1, 1998 between Debtor and Secured Party (such
Amended and Restated Credit Agreement as the same may be amended or supplemented
from time to time called the "Credit Agreement"; unless otherwise defined
herein, terms used herein and defined in the Credit Agreement shall be used
herein as so defined); and

         WHEREAS, it is a condition precedent to the incurrence of Loans and the
issuance of Letters of Credit and Guarantees under the Credit Agreement that
Debtor shall have executed and delivered to Secured Party this Agreement; and

         WHEREAS, Debtor desires to execute this Agreement to satisfy the
condition described in the preceding paragraph;

         NOW, THEREFORE, in consideration of the benefits to Debtor, the receipt
and sufficiency of which are hereby acknowledged, Debtor hereby makes the
following representations and warranties to Secured Party and hereby covenants
and agrees with Secured Party as follows:

                          SECTION 1. SECURITY INTERESTS

         1.01.  Grant of Security Interests. (a) As security for the prompt and
complete payment and performance when due of all of its Obligations (all
capitalized terms used herein and defined in Section 7.01 shall be used herein
as so defined), Debtor does hereby sell, assign and transfer unto Secured Party,
and does hereby grant to Secured Party a continuing security interest of first
priority (subject to Excepted Liens) in, all of the right, title and interest of
Debtor in, to and under all of the following, whether now existing or hereafter
from time to time acquired: (i) each and every Receivable; (ii) all Inventory;
(iii) the Cash Collateral Account and all monies, securities and instruments
deposited or required to be deposited in the Cash Collateral Account; and (iv)
all Proceeds and products of any and all of the foregoing (all of the above,
collectively, the "Collateral").

         (b)    The security interest of Secured Party under this Agreement 
extends to all Collateral of the kind described in preceding clause (a) which
Debtor may acquire at any time during the continuation of this Agreement.

         1.02.  Power of Attorney. Debtor hereby constitutes and appoints 
Secured Party its true and lawful attorney, irrevocably, with full power after
the occurrence of an Event of Default (in 


                                       1

<PAGE>   110

the name of Debtor or otherwise) to act, require, demand, receive, compound and
give acquittance for any and all monies and claims for monies due or to become
due to Debtor under or arising out of the Collateral, to endorse any checks or
other instruments or orders in connection therewith and to file any claims or
take any action or institute any proceedings which Secured Party may deem to be
necessary or advisable in the premises, which appointment as attorney is coupled
with an interest.

          SECTION 2. GENERAL REPRESENTATIONS. WARRANTIES AND COVENANTS

         Debtor represents, warrants and covenants, which representations,
warranties and covenants shall survive execution and delivery of this Agreement,
as follows:

         2.01.  Necessary Filings. All filings, registrations and recordings
necessary or appropriate to create, preserve, protect and perfect the security
interest granted by Debtor to Secured Party hereby in respect of the Collateral
have been accomplished and the security interest granted to Secured Party
pursuant to this Agreement in and to the Collateral constitutes a valid and
enforceable perfected security interest therein superior and prior to the rights
of all other Persons therein and subject to no other Liens (except that the
Collateral may be subject to Excepted Liens) and is entitled to all the rights,
priorities and benefits afforded by the Uniform Commercial Code or other
relevant law as enacted in any relevant jurisdiction to perfected security
interests.

         2.02.  No Liens. Debtor is, and as to Collateral acquired by it from
time to time after the date hereof Debtor will be, the owner of all Collateral
free from any Lien or other right, title or interest of any Person (other than
Excepted Liens and Liens permitted under Section 10.01(i) and (iv) of the Credit
Agreement), and Debtor shall defend the Collateral against all claims and
demands of all Persons at any time claiming the same or any interest therein
adverse to Secured Party.

         2.03.  Other Financing Statements. There is no financing statement (or
similar statement or instrument of registration under the law of any
jurisdiction) covering or purporting to cover any interest of any kind in the
Collateral except as disclosed in Annex A and so long as the Total Commitment
has not been terminated or any of the Obligations remain unpaid or any Letters
of Credit or Guarantees are outstanding, Debtor will not execute or authorize to
be filed in any public office any financing statement (or similar statement or
instrument of registration under the law of any jurisdiction) or statements
relating to the Collateral, except financing statements filed or to be filed in
respect of and covering the security interests granted hereby by Debtor.

         2.04.  Chief Executive Office; Records. The chief executive office of
Debtor is located at Houston, Texas. Debtor will not move its chief executive
office except to such new location as Debtor may establish in accordance with
the last sentence of this Section 2.04. The originals of all documents
evidencing all Receivables of Debtor and the only original books of account and
records of Debtor relating thereto are, and will continue to be, kept at such
chief executive office or at the locations disclosed in Annex B, or at such new
locations as Debtor may establish in accordance with the last sentence of this
Section 2.04. All Receivables of Debtor are, and will continue to be, maintained
at, and controlled and directed (including, without limitation, for 

                                       2

<PAGE>   111

general accounting purposes) from, such office locations shown above, or such
new locations as Debtor may establish in accordance with the last sentence of
this Section 2.04. Debtor shall not establish a new location for such offices
until (i) it shall have given to Secured Party not less than 45 days' prior
written notice of its intention so to do, clearly describing such new location
and providing such other information in connection therewith as Secured Party
may reasonably request and (ii) with respect to such new location, it shall have
taken all action, satisfactory to Secured Party, to maintain the security
interest of Secured Party in the Collateral intended to be granted hereby at all
times fully perfected and in full force and effect.

         2.05.  Location of Inventory. All Inventory included in the Borrowing
Base is subject to a perfected first priority security interest (subject to
Excepted Liens). Financing statements covering the Inventory have been filed in
the filing jurisdictions listed on Annex C.

         2.06.  Recourse. This Agreement is made with full recourse to Debtor 
and pursuant to and upon all the warranties, representations, covenants and
agreements on the part of Debtor contained herein, in the Credit Agreement and
otherwise in writing in connection herewith or therewith. This Agreement is
non-recourse to the General Partner as provided in Section 12.15 of the Credit
Agreement.

              SECTION 3. SPECIAL PROVISIONS CONCERNING RECEIVABLES

         3.01.  Additional Representations and Warranties. As of the time when
each of its Receivable arises, Debtor shall be deemed to have represented and
warranted that such Receivable, and all records, papers and documents relating
thereto (if any) are genuine and in all respects what they purport to be, and
that all papers and documents (if any) relating thereto (i) will represent the
genuine, legal, valid and binding obligation of the account debtor evidencing
indebtedness unpaid and owed by the respective account debtor arising out of the
performance of labor or services or the sale or lease and delivery of the
merchandise listed therein, or both, (ii) will be the only original writings
evidencing and embodying such obligation of the account debtor named therein
(other than copies created for general accounting purposes), (iii) will evidence
true and valid obligations, enforceable in accordance with their respective
terms and (iv) will be in compliance and will conform with all applicable
federal, state, provincial and local laws and applicable laws of any relevant
foreign jurisdiction.

         3.02.  Maintenance of Records. Debtor will keep and maintain at its own
cost and expense satisfactory and complete records of its Receivables,
including, but not limited to, the originals of all documentation with respect
thereto, records of all payments received, all credits granted thereon, all
merchandise returned and all other dealings therewith, and Debtor will make the
same available to Secured Party for inspection, at Debtor's own cost and
expense, at any and all reasonable times upon demand. Debtor shall, at its own
cost and expense, deliver all tangible evidence of its Receivables (including,
without limitation, all documents evidencing the Receivables) and such books and
records to Secured Party or to its representatives (copies of which evidence and
books and records may be retained by Debtor) at any time upon its demand. If
Secured Party so directs, Debtor shall legend, in form and manner reasonably
satisfactory to Secured Party, the Receivables, as well as books, records and
documents of Debtor evidencing or 

                                       3

<PAGE>   112

pertaining to the Receivables with an appropriate reference to the fact that the
Receivables have been assigned to Secured Party and that Secured Party has a
security interest therein.

         3.03.  Direction to Account Debtors; Contracting Parties; etc. Upon the
occurrence of an Event of Default and if Secured Party so directs, Debtor agrees
(i) to cause all payments on account of the Receivables to be made directly to
the Cash Collateral Account and (ii) that Secured Party may, at its option,
directly notify the obligors with respect to any Receivables to make payments
with respect thereto as provided in preceding clause (i). Without notice to or
assent by Debtor, Secured Party may apply any or all amounts then in, or
thereafter deposited in, the Cash Collateral Account in the manner provided in
Section 7.04 of this Agreement. The costs and expenses (including attorneys'
fees) of collection, whether incurred by Debtor or Secured Party, shall be borne
by Debtor.

         3.04.  Modification of Terms; etc. Debtor shall not rescind or cancel
any indebtedness evidenced by or rights covered by the security interest hereby
granted, as Secured Party may reasonably require.

                 SECTION 4. PROVISIONS CONCERNING ALL COLLATERAL

         4.01.  Protection of Secured Party's Security. Debtor will do nothing 
to impair the rights of Secured Party in the Collateral. Debtor will at all
times keep its Inventory insured in favor of Secured Party, at its own expense,
to Secured Party's reasonable satisfaction against fire, theft and all other
risks to which such Collateral may be subject; all policies or certificates with
respect to such insurance shall be endorsed to Secured Party's satisfaction for
the benefit of Secured Party (including, without limitation, by naming Secured
Party as loss payee) and deposited with Secured Party. If Debtor shall fail to
insure such Inventory to Secured Party's reasonable satisfaction, or if Debtor
shall fail to so endorse and deposit all policies or certificates with respect
thereto, Secured Party shall have the right (but shall be under no obligation)
to procure such insurance and Debtor agrees to reimburse Secured Party for all
costs and expenses of procuring such insurance. Secured Party may apply any
proceeds of such insurance when received by it toward the payment of any of the
Obligations to the extent the same shall then be due. Debtor assumes all
liability and responsibility in connection with the Collateral acquired by it
and the liability of Debtor to pay its Obligations shall in no way be affected
or diminished by reason of the fact that such Collateral may be lost, destroyed,
stolen, damaged or for any reason whatsoever unavailable to Debtor.

         4.02.  Warehouse Receipts Non-negotiable. Debtor agrees that if any
warehouse receipt or receipt in the nature of a warehouse receipt is issued with
respect to any of its Inventory, such warehouse receipt or receipt in the nature
thereof shall not be "negotiable" (as such term is used in Section 7-104 of the
Uniform Commercial Code as in effect in any relevant jurisdiction or under other
relevant law).

         4.03.  Further Actions. Debtor will, at its own expense, make, execute,
endorse, acknowledge, file and/or deliver to Secured Party from time to time
such lists, descriptions and designations of its Collateral, warehouse receipts,
receipts in the nature of warehouse receipts, bills of lading, documents of
title, vouchers, invoices, schedules, confirmatory assignments, conveyances,
financing statements, transfer endorsements, powers of attorney, certificates,

                                       4

reports and other assurances or instruments and take such further steps relating
to the Collateral and other property or rights covered by the security interest
hereby granted, which Secured Party deems reasonably appropriate or advisable to
perfect, preserve or protect its security interest in the Collateral.

         4.04.  Financing Statements. Debtor agrees to assign and deliver to
Secured Party such financing statements, in form acceptable to Secured Party, as
Secured Party may from time to time reasonably request or as are necessary or
desirable in the opinion of Secured Party to establish and maintain a valid,
enforceable, first priority security interest in the Collateral as provided
herein and the other rights and security contemplated herein, all in accordance
with the Uniform Commercial Code as enacted in any and all relevant
jurisdictions or any other relevant law. Debtor will pay any applicable filing
fees and related expenses. Debtor authorizes Secured Party to file any such
financing statements without the signature of Debtor.

             SECTION 5. REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

         5.01.  Remedies; Obtaining the Collateral Upon Default. Debtor agrees
that, if any Event of Default shall have occurred and be continuing, then and in
every such case, subject to any mandatory requirements of applicable law then in
effect, Secured Party , in addition to any rights now or hereafter existing
under applicable law, shall have all rights as a secured creditor under the
Uniform Commercial Code in all relevant jurisdictions and may:

                (a)   personally, or by agents, receiver, receiver and manager
         or attorneys, immediately retake possession of the Collateral or any
         part thereof, from Debtor or any other Person who then has possession
         of any part thereof with or without notice or process of law, and for
         that purpose may enter upon Debtor's premises where any of the
         Collateral is located and remove the same and use in connection with
         such removal any and all services, supplies, aids and other facilities
         of Debtor; and

                (b)   instruct the obligor or obligors on any agreement,
         instrument or other obligation (including, without limitation, the
         Receivables) constituting the Collateral to make any payment required
         by the terms of such instrument or agreement directly to Secured Party;
         and

                (c)   withdraw all monies, securities and instruments in the
         Cash Collateral Account for application to the Obligations; and

                (d)   sell, assign or otherwise liquidate, or direct Debtor to
         sell, assign or otherwise liquidate, any or all of the Collateral or
         any part thereof, and take possession of the proceeds of any such sale
         or liquidation; and

                (e)   take possession of the Collateral or any part thereof, by
         directing Debtor in writing to deliver the same to Secured Party at any
         place or places designated by Secured Party, in which event Debtor
         shall at its own expense:

                                       5

<PAGE>   114

                           (i) forthwith cause the same to be moved to the place
                  or places so designated by Secured Party and there delivered
                  to Secured Party,

                           (ii) store and keep any Collateral so delivered to
                  Secured Party at such place or places pending further action
                  by Secured Party as provided in Section 5.02, and

                           (iii) while the Collateral shall be so stored and
                  kept, provide such guards and maintenance services as shall be
                  necessary to protect the same and to preserve and maintain
                  them in good condition;

         it being understood that Debtor's obligation so to deliver the
         Collateral is of the essence of this Agreement and that, accordingly,
         upon application to a court of equity having jurisdiction, Secured
         Party shall be entitled to a decree requiring specific performance by
         Debtor of such obligation.

         5.02.  Remedies; Disposition of the Collateral. Any Collateral
repossessed by Secured Party under or pursuant to Section 5.01, and any other
Collateral whether or not so repossessed by Secured Party, may be sold,
assigned, leased or otherwise disposed of under one or more contracts or as an
entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as Secured Party may, in compliance with
any mandatory requirements of applicable law, determine to be commercially
reasonable. Any of the Collateral may be sold, leased or otherwise disposed of,
in the condition in which the same existed when taken by Secured Party or after
any overhaul or repair which Secured Party shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceeding permitted by such requirements shall be made upon not less than 10
days' written notice to Debtor specifying the time at which such disposition is
to be made and the intended sale price or other consideration therefor, and
shall be subject, for the 10 days after the giving of such notice, to the right
of Debtor or any nominee of Debtor to acquire the Collateral involved at a price
or for such other consideration at least equal to the intended sale price or
other consideration so specified. Any such disposition which shall be a public
sale permitted by such requirements shall be made upon not less than 10 days'
written notice to Debtor specifying the time and place of such sale and, in the
absence of applicable requirements of law, shall be by public auction (which
may, at Secured Party's option, be subject to reserve), after publication of
notice of such auction not less than 10 days prior thereto in two newspapers in
general circulation in Houston, Texas. To the extent permitted by any such
requirement of law, Secured Party may bid for and become the purchaser of the
Collateral or any item thereof, offered for sale in accordance with this Section
5.02 without accountability to Debtor (except to the extent of surplus money
received as provided in Section 5.04). If, under mandatory requirements of
applicable law, Secured Party shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Debtor as hereinabove specified, Secured Party need give Debtor only such notice
of disposition as shall be reasonably practicable in view of such mandatory
requirements of applicable law.

         5.03.  Waiver of Claims. Except as otherwise provided in this 
Agreement, DEBTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW,
NOTICE AND JUDICIAL HEARING IN CONNECTION WITH SECURED PARTY'S TAKING POSSESSION
OR SECURED PARTY'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT
LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR
REMEDIES AND ANY SUCH RIGHT WHICH DEBTOR WOULD OTHERWISE HAVE UNDER THE
CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and Debtor
hereby further waives, to the extent permitted by law:

                  (i)   all damages occasioned by such taking of possession 
         except any damages which are the direct result of Secured Party's gross
         negligence or willful misconduct;

                  (ii)  all other requirements as to the time, place and terms 
         of sale or other requirements with respect to the enforcement of 
         Secured Party's rights hereunder; and

                  (iii) all rights of redemption, appraisement, valuation, stay,
         extension or moratorium now or hereafter in force under any applicable
         law in order to prevent or delay the enforcement of this Agreement or
         the absolute sale of the Collateral or any portion thereof, and Debtor,
         for itself and all who may claim under it, insofar as it or they now or
         hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of Debtor therein and thereto, and shall be
a perpetual bar both at law and in equity against Debtor and against any and all
Persons claiming or attempting to claim the Collateral so sold, optioned or
realized upon, or any part thereof, from, through and under Debtor.

         5.04.  Application of Proceeds. The proceeds of any Collateral obtained
pursuant to Section 5.01 or disposed of pursuant to Section 5.02 shall be
applied as follows:

                  (i)   to the payment of any and all expenses and fees 
         (including reasonable attorneys' fees) incurred by Secured Party in 
         obtaining, taking possession of, removing, insuring, repairing, storing
         and disposing of Collateral and any and all amounts incurred by Secured
         Party in connection therewith;

                  (ii)  next, any surplus then remaining to the payment of the
         Obligations in the following order of priority:

                        (t)   all interest accrued and unpaid and all fees  
                  payable pursuant to Section 5.01(a) or (b) of the Credit 
                  Agreement;

                        (u)   the principal amount owing on the Loans and all
                  amounts with respect to Letter of Credit Outstandings and
                  Guarantee Outstandings;

                        (v)   all other Obligations then owing;

                                       7

<PAGE>   116

                  (iii) if the Total Commitment is then terminated, no Letter of
         Credit is outstanding and no other Obligation is outstanding, any
         surplus then remaining shall be paid to Debtor, subject, however, to
         the rights of the holder of any then existing Lien of which Secured
         Party has actual notice (without investigation);

it being understood that Debtor shall remain liable to the extent of any
deficiency between the amount of the proceeds of the Collateral and the
aggregate amount of the sums referred to in clauses (i) and (ii) of this Section
5.04 with respect to Debtor.

         5.05.  Remedies Cumulative. No failure or delay on the part of Secured
Party in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between Debtor and Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Credit Document preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege hereunder or thereunder. The rights, powers and remedies herein or
in any other Credit Document expressly provided are cumulative and not exclusive
of any rights, powers or remedies which Secured Party would otherwise have. No
notice to or demand on Debtor in any case shall entitle Debtor to any other or
further notice or demand in similar or other circumstances or constitute a
waiver of the rights of Secured Party to any other or further action in any
circumstances without notice or demand.

         5.06.  Discontinuance of Proceedings. In case Secured Party shall have
instituted any proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to Secured Party, then and in every such case Debtor, Secured Party
shall be restored to its former position and rights hereunder with respect to
the Collateral subject to the security interest created under this Agreement,
and all rights, remedies and powers of Secured Party shall continue as if no
such proceeding had been instituted.

                              SECTION 6. INDEMNITY

         6.01.  Indemnity. (a) Debtor agrees to indemnify, reimburse and hold
Secured Party and its officers, directors, employees, representatives and agents
(hereinafter in this Section 6.01 referred to individually as "Indemnitee" and
collectively as "Indemnitees") harmless from any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, suits,
costs, expenses or disbursements (including reasonable attorneys' fees and
expenses) (for the purposes of this Section 6.01 the foregoing are collectively
called "expenses") of whatsoever kind or nature which may be imposed on,
asserted against or incurred by any of the Indemnitees in any way relating to or
arising out of this Agreement, any other Credit Document or the documents
executed in connection herewith and therewith or in any other way connected with
the administration of the transactions contemplated hereby and thereby or the
enforcement of any of the terms of or the preservation of any rights under any
thereof, or in any way relating to or arising out of the manufacture, ownership,
ordering, purchase, delivery, control, acceptance, lease, financing, possession,
operation, condition, sale, return or other disposition or use of the Collateral
(including, without limitation, latent or other defects, whether or not
discoverable), the 

                                       8

<PAGE>   117

violation of the laws of any country, state or other governmental body or unit,
any tort (including, without limitation, claims arising or imposed under the
doctrine of strict liability, or for or on account of injury to or the death of
any Person (including any Indemnitee), or for property damage) or any contract
claim; provided that no Indemnitee shall be indemnified pursuant to this Section
6.01(a) for expenses to the extent caused by the gross negligence or willful
misconduct of such Indemnitee. Debtor agrees that upon written notice by any
Indemnitee of any assertion that could give rise to an expense, Debtor shall
assume full responsibility for the defense thereof. Each Indemnitee agrees to
use its best efforts to promptly notify Debtor of any such assertion of which
such Indemnitee has knowledge.

         (b)    Without limiting the application of Section 6.01(a), Debtor 
agrees to pay, or reimburse Secured Party for (if Secured Party shall have
incurred fees, costs or expenses because Debtor shall have failed to comply with
its obligations under this Assignment or any other Credit Document), any and all
fees, costs and expenses of whatever kind or nature incurred in connection with
the creation, preservation or protection of Secured Party's Liens on, and
security interest in, the Collateral, including, without limitation, all fees
and taxes in connection with the recording or filing of instruments and
documents in public offices, payment or discharge of any taxes or Liens upon or
in respect of the Collateral, premiums for insurance with respect to the
Collateral and all other fees, costs and expenses in connection with protecting,
maintaining or preserving the Collateral and Secured Party's interest therein,
whether through judicial proceedings or otherwise, or in defending or
prosecuting any actions, suits or proceedings arising out of or relating to the
Collateral.

         (c)    Without limiting the application of Section 6.01(a) or (b), 
Debtor agrees to pay, indemnify and hold each Indemnitee harmless from and
against any expenses which such Indemnitee may suffer, expend or incur in
consequence of or growing out of any misrepresentation by Debtor in this
Agreement or any of the other Credit Documents or in any statement or writing
contemplated by or made or delivered pursuant to or in connection with this
Agreement or any of the other Credit Documents.

         (d)    If and to the extent that the obligations of Debtor under this
Section 6.01 are unenforceable for any reason, Debtor hereby agrees to make the
maximum contribution to the payment and satisfaction of such obligations which
is permissible under applicable law.

         6.02.  Indemnity Obligations Secured by Collateral; Survival. Any
amounts paid by any Indemnitee as to which such Indemnitee has the right to
reimbursement shall constitute Obligations secured by the Collateral. The
indemnity obligations of Debtor contained in this Article VIII shall continue in
full force and effect notwithstanding the full payment of the Note and all of
the other Obligations and notwithstanding the discharge thereof.

                             SECTION 7. DEFINITIONS

         2.02. No Liens. Debtor is, and as to Collateral acquired by it from
time to time after the date hereof Debtor will be, the owner of all Collateral
free from any Lien or other right, title or interest of any Person (other than
Excepted Liens and Liens permitted under Section 10.01(i) and (iv) of the Credit
Agreement), and Debtor shall defend the Collateral against all claims and
demands of all Persons at any time claiming the same or any interest therein
adverse to Secured Party.

         2.03. Other Financing Statements. There is no financing statement (or
similar statement or instrument of registration under the law of any
jurisdiction) covering or purporting to cover any interest of any kind in the
Collateral except as disclosed in Annex A and so long as the Total Commitment
has not been terminated or any of the Obligations remain unpaid or any Letters
of Credit or Guarantees are outstanding, Debtor will not execute or authorize to
be filed in any public office any financing statement (or similar statement or
instrument of registration under the law of any jurisdiction) or statements
relating to the Collateral, except financing statements filed or to be filed in
respect of and covering the security interests granted hereby by Debtor.

         2.04. Chief Executive Office; Records. The chief executive office of
Debtor is located at Houston, Texas. Debtor will not move its chief executive
office except to such new location as Debtor may establish in accordance with
the last sentence of this Section 2.04. The originals of all documents
evidencing all Receivables of Debtor and the only original books of account and
records of Debtor relating thereto are, and will continue to be, kept at such
chief executive office or at the locations disclosed in Annex B, or at such new
locations as Debtor may establish in accordance with the last sentence of this
Section 2.04. All Receivables of Debtor are, and will continue to be, maintained
at, and controlled and directed (including, without limitation, for general
accounting purposes) from, such office locations shown above, or such new
locations as Debtor may establish in accordance with the last sentence of this
Section 2.04. Debtor shall not establish a new location for such offices until
(i) it shall have given to Secured Party not less than 45 days' prior written
notice of its intention so to do, clearly describing such new location and
providing such other information in connection therewith as Secured Party may
reasonably request


                                       2
<PAGE>   132

and (ii) with respect to such new location, it shall have taken all action,
satisfactory to Secured Party, to maintain the security interest of Secured
Party in the Collateral intended to be granted hereby at all times fully
perfected and in full force and effect.

         2.05. Location of Inventory. All Inventory included in the Borrowing
Base is subject to a perfected first priority security interest (subject to
Excepted Liens). Financing statements covering the Inventory have been filed in
the filing jurisdictions listed on Annex C.

         2.06. Recourse. This Agreement is made with full recourse to Debtor and
pursuant to and upon all the warranties, representations, covenants and
agreements on the part of Debtor contained herein, in the Credit Agreement and
otherwise in writing in connection herewith or therewith. This Agreement is
non-recourse to the General Partner as provided in Section 12.15 of the Credit
Agreement.

         SECTION 3. SPECIAL PROVISIONS CONCERNING RECEIVABLES

         3.01. Additional Representations and Warranties. As of the time when
each of its Receivable arises, Debtor shall be deemed to have represented and
warranted that such Receivable, and all records, papers and documents relating
thereto (if any) are genuine and in all respects what they purport to be, and
that all papers and documents (if any) relating thereto (i) will represent the
genuine, legal, valid and binding obligation of the account debtor evidencing
indebtedness unpaid and owed by the respective account debtor arising out of the
performance of labor or services or the sale or lease and delivery of the
merchandise listed therein, or both, (ii) will be the only original writings
evidencing and embodying such obligation of the account debtor named therein
(other than copies created for general accounting purposes), (iii) will evidence
true and valid obligations, enforceable in accordance with their respective
terms and (iv) will be in compliance and will conform with all applicable
federal, state, provincial and local laws and applicable laws of any relevant
foreign jurisdiction.

         3.02. Maintenance of Records. Debtor will keep and maintain at its own
cost and expense satisfactory and complete records of its Receivables,
including, but not limited to, the originals of all documentation with respect
thereto, records of all payments received, all credits granted thereon, all
merchandise returned and all other dealings therewith, and Debtor will make the
same available to Secured Party for inspection, at Debtor's own cost and
expense, at any and all reasonable times upon demand. Debtor shall, at its own
cost and expense, deliver all tangible evidence of its Receivables (including,
without limitation, all documents evidencing the Receivables) and such books and
records to Secured Party or to its representatives (copies of which evidence and
books and records may be retained by Debtor) at any time upon its demand. If
Secured Party so directs, Debtor shall legend, in form and manner reasonably
satisfactory to Secured Party, the Receivables, as well as books, records and
documents of Debtor evidencing or pertaining to the Receivables with an
appropriate reference to the fact that the Receivables have been assigned to
Secured Party and that Secured Party has a security interest therein.

         3.03. Direction to Account Debtors; Contracting Parties; etc. Upon the
occurrence of an Event of Default and if Secured Party so directs, Debtor agrees
(i) to cause all payments on account of the Receivables to be made directly to
the Cash Collateral Account and (ii) that Secured Party may, at its option,
directly notify the obligors with respect to any Receivables to make payments


                                       3
<PAGE>   133


with respect thereto as provided in preceding clause (i). Without notice to or
assent by Debtor, Secured Party may apply any or all amounts then in, or
thereafter deposited in, the Cash Collateral Account in the manner provided in
Section 7.04 of this Agreement. The costs and expenses (including attorneys'
fees) of collection, whether incurred by Debtor or Secured Party, shall be borne
by Debtor.

         3.04. Modification of Terms; etc. Debtor shall not rescind or cancel
any indebtedness evidenced by or rights covered by the security interest hereby
granted, as Secured Party may reasonably require.

                SECTION 4. PROVISIONS CONCERNING ALL COLLATERAL

         4.01. Protection of Secured Party's Security. Debtor will do nothing to
impair the rights of Secured Party in the Collateral. Debtor will at all times
keep its Inventory insured in favor of Secured Party, at its own expense, to
Secured Party's reasonable satisfaction against fire, theft and all other risks
to which such Collateral may be subject; all policies or certificates with
respect to such insurance shall be endorsed to Secured Party's satisfaction for
the benefit of Secured Party (including, without limitation, by naming Secured
Party as loss payee) and deposited with Secured Party. If Debtor shall fail to
insure such Inventory to Secured Party's reasonable satisfaction, or if Debtor
shall fail to so endorse and deposit all policies or certificates with respect
thereto, Secured Party shall have the right (but shall be under no obligation)
to procure such insurance and Debtor agrees to reimburse Secured Party for all
costs and expenses of procuring such insurance. Secured Party may apply any
proceeds of such insurance when received by it toward the payment of any of the
Obligations to the extent the same shall then be due. Debtor assumes all
liability and responsibility in connection with the Collateral acquired by it
and the liability of Debtor to pay its Obligations shall in no way be affected
or diminished by reason of the fact that such Collateral may be lost, destroyed,
stolen, damaged or for any reason whatsoever unavailable to Debtor.

         4.02. Warehouse Receipts Non-negotiable. Debtor agrees that if any
warehouse receipt or receipt in the nature of a warehouse receipt is issued with
respect to any of its Inventory, such warehouse receipt or receipt in the nature
thereof shall not be "negotiable" (as such term is used in Section 7-104 of the
Uniform Commercial Code as in effect in any relevant jurisdiction or under other
relevant law).

         4.03. Further Actions. Debtor will, at its own expense, make, execute,
endorse, acknowledge, file and/or deliver to Secured Party from time to time
such lists, descriptions and designations of its Collateral, warehouse receipts,
receipts in the nature of warehouse receipts, bills of lading, documents of
title, vouchers, invoices, schedules, confirmatory assignments, conveyances,
financing statements, transfer endorsements, powers of attorney, certificates,
reports and other assurances or instruments and take such further steps relating
to the Collateral and other property or rights covered by the security interest
hereby granted, which Secured Party deems reasonably appropriate or advisable to
perfect, preserve or protect its security interest in the Collateral.

         4.04. Financing Statements. Debtor agrees to assign and deliver to
Secured Party such financing statements, in form acceptable to Secured Party, as
Secured Party may from time to time reasonably request or as are necessary or
desirable in the opinion of Secured Party to establish and


                                       5
<PAGE>   134

maintain a valid, enforceable, first priority security interest in the
Collateral as provided herein and the other rights and security contemplated
herein, all in accordance with the Uniform Commercial Code as enacted in any and
all relevant jurisdictions or any other relevant law. Debtor will pay any
applicable filing fees and related expenses. Debtor authorizes Secured Party to
file any such financing statements without the signature of Debtor.

            SECTION 5. REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

         5.01. Remedies; Obtaining the Collateral Upon Default. Debtor agrees
that, if any Event of Default shall have occurred and be continuing, then and in
every such case, subject to any mandatory requirements of applicable law then in
effect, Secured Party , in addition to any rights now or hereafter existing
under applicable law, shall have all rights as a secured creditor under the
Uniform Commercial Code in all relevant jurisdictions and may:

                  (a) personally, or by agents, receiver, receiver and manager
         or attorneys, immediately retake possession of the Collateral or any
         part thereof, from Debtor or any other Person who then has possession
         of any part thereof with or without notice or process of law, and for
         that purpose may enter upon Debtor's premises where any of the
         Collateral is located and remove the same and use in connection with
         such removal any and all services, supplies, aids and other facilities
         of Debtor; and

                  (b) instruct the obligor or obligors on any agreement,
         instrument or other obligation (including, without limitation, the
         Receivables) constituting the Collateral to make any payment required
         by the terms of such instrument or agreement directly to Secured Party;
         and

                  (c) withdraw all monies, securities and instruments in the
         Cash Collateral Account for application to the Obligations; and

                  (d) sell, assign or otherwise liquidate, or direct Debtor to
         sell, assign or otherwise liquidate, any or all of the Collateral or
         any part thereof, and take possession of the proceeds of any such sale
         or liquidation; and

                  (e) take possession of the Collateral or any part thereof, by
         directing Debtor in writing to deliver the same to Secured Party at any
         place or places designated by Secured Party, in which event Debtor
         shall at its own expense:

                         (i)    forthwith cause the same to be moved to the 
                    place or places so designated by Secured Party and there
                    delivered to Secured Party,

                         (ii)   store and keep any Collateral so delivered to
                    Secured Party at such place or places pending further action
                    by Secured Party as provided in Section 5.02, and

                         (iii)  while the Collateral shall be so stored and
                    kept, provide such guards and maintenance services as shall
                    be necessary to protect the same and to preserve and
                    maintain them in good condition;


                                       5
<PAGE>   135

                    it being understood that Debtor's obligation so to deliver
                    the Collateral is of the essence of this Agreement and that,
                    accordingly, upon application to a court of equity having
                    jurisdiction, Secured Party shall be entitled to a decree
                    requiring specific performance by Debtor of such obligation.

         5.02. Remedies; Disposition of the Collateral. Any Collateral
repossessed by Secured Party under or pursuant to Section 5.01, and any other
Collateral whether or not so repossessed by Secured Party, may be sold,
assigned, leased or otherwise disposed of under one or more contracts or as an
entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as Secured Party may, in compliance with
any mandatory requirements of applicable law, determine to be commercially
reasonable. Any of the Collateral may be sold, leased or otherwise disposed of,
in the condition in which the same existed when taken by Secured Party or after
any overhaul or repair which Secured Party shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceeding permitted by such requirements shall be made upon not less than 10
days' written notice to Debtor specifying the time at which such disposition is
to be made and the intended sale price or other consideration therefor, and
shall be subject, for the 10 days after the giving of such notice, to the right
of Debtor or any nominee of Debtor to acquire the Collateral involved at a price
or for such other consideration at least equal to the intended sale price or
other consideration so specified. Any such disposition which shall be a public
sale permitted by such requirements shall be made upon not less than 10 days'
written notice to Debtor specifying the time and place of such sale and, in the
absence of applicable requirements of law, shall be by public auction (which
may, at Secured Party's option, be subject to reserve), after publication of
notice of such auction not less than 10 days prior thereto in two newspapers in
general circulation in Houston, Texas. To the extent permitted by any such
requirement of law, Secured Party may bid for and become the purchaser of the
Collateral or any item thereof, offered for sale in accordance with this Section
5.02 without accountability to Debtor (except to the extent of surplus money
received as provided in Section 5.04). If, under mandatory requirements of
applicable law, Secured Party shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Debtor as hereinabove specified, Secured Party need give Debtor only such notice
of disposition as shall be reasonably practicable in view of such mandatory
requirements of applicable law.

         5.03. Waiver of Claims. Except as otherwise provided in this Agreement,
DEBTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND
JUDICIAL HEARING IN CONNECTION WITH SECURED PARTY'S TAKING POSSESSION OR SECURED
PARTY'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY
AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY
SUCH RIGHT WHICH DEBTOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY
STATUTE OF THE UNITED STATES OR OF ANY STATE, and Debtor hereby further waives,
to the extent permitted by law:

         (i)    all damages occasioned by such taking of possession except any
     damages which are the direct result of Secured Party's gross negligence or
     willful misconduct;


                                       6
<PAGE>   136

         (ii)   all other requirements as to the time, place and terms of sale
     or other requirements with respect to the enforcement of Secured Party's
     rights hereunder; and

         (iii)  all rights of redemption, appraisement, valuation, stay,
     extension or moratorium now or hereafter in force under any applicable law
     in order to prevent or delay the enforcement of this Agreement or the
     absolute sale of the Collateral or any portion thereof, and Debtor, for
     itself and all who may claim under it, insofar as it or they now or
     hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of Debtor therein and thereto, and shall be
a perpetual bar both at law and in equity against Debtor and against any and all
Persons claiming or attempting to claim the Collateral so sold, optioned or
realized upon, or any part thereof, from, through and under Debtor.

         5.04. Application of Proceeds. The proceeds of any Collateral obtained
pursuant to Section 5.01 or disposed of pursuant to Section 5.02 shall be
applied as follows:

         (i) to the payment of any and all expenses and fees (including
     reasonable attorneys' fees) incurred by Secured Party in obtaining, taking
     possession of, removing, insuring, repairing, storing and disposing of
     Collateral and any and all amounts incurred by Secured Party in connection
     therewith;

         (ii) next, any surplus then remaining to the payment of the Obligations
     in the following order of priority:

              (t) all interest accrued and unpaid and all fees payable pursuant
     to Section 5.01(a) or (b) of the Credit Agreement;

              (u) the principal amount owing on the Loans and all amounts with
     respect to Letter of Credit Outstandings and Guarantee Outstandings;

              (v) all other Obligations then owing;

         (iii) if the Total Commitment is then terminated, no Letter of Credit
     is outstanding and no other Obligation is outstanding, any surplus then
     remaining shall be paid to Debtor, subject, however, to the rights of the
     holder of any then existing Lien of which Secured Party has actual notice
     (without investigation);

it being understood that Debtor shall remain liable to the extent of any
deficiency between the amount of the proceeds of the Collateral and the
aggregate amount of the sums referred to in clauses (i) and (ii) of this Section
5.04 with respect to Debtor.

         5.05. Remedies Cumulative. No failure or delay on the part of Secured
Party in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between Debtor and Secured Party shall
operate as a waiver thereof; nor shall


                                       7
<PAGE>   137

any single or partial exercise of any right, power or privilege hereunder or
under any other Credit Document preclude any other or further exercise thereof
or the exercise of any other right, power or privilege hereunder or thereunder.
The rights, powers and remedies herein or in any other Credit Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies
which Secured Party would otherwise have. No notice to or demand on Debtor in
any case shall entitle Debtor to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of Secured
Party to any other or further action in any circumstances without notice or
demand.

         5.06. Discontinuance of Proceedings. In case Secured Party shall have
instituted any proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to Secured Party, then and in every such case Debtor, Secured Party
shall be restored to its former position and rights hereunder with respect to
the Collateral subject to the security interest created under this Agreement,
and all rights, remedies and powers of Secured Party shall continue as if no
such proceeding had been instituted.

                              SECTION 6. INDEMNITY

         6.01. Indemnity. (a) Debtor agrees to indemnify, reimburse and hold
Secured Party and its officers, directors, employees, representatives and agents
(hereinafter in this Section 6.01 referred to individually as "Indemnitee" and
collectively as "Indemnitees") harmless from any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, suits,
costs, expenses or disbursements (including reasonable attorneys' fees and
expenses) (for the purposes of this Section 6.01 the foregoing are collectively
called "expenses") of whatsoever kind or nature which may be imposed on,
asserted against or incurred by any of the Indemnitees in any way relating to or
arising out of this Agreement, any other Credit Document or the documents
executed in connection herewith and therewith or in any other way connected with
the administration of the transactions contemplated hereby and thereby or the
enforcement of any of the terms of or the preservation of any rights under any
thereof, or in any way relating to or arising out of the manufacture, ownership,
ordering, purchase, delivery, control, acceptance, lease, financing, possession,
operation, condition, sale, return or other disposition or use of the Collateral
(including, without limitation, latent or other defects, whether or not
discoverable), the violation of the laws of any country, state or other
governmental body or unit, any tort (including, without limitation, claims
arising or imposed under the doctrine of strict liability, or for or on account
of injury to or the death of any Person (including any Indemnitee), or for
property damage) or any contract claim; provided that no Indemnitee shall be
indemnified pursuant to this Section 6.01(a) for expenses to the extent caused
by the gross negligence or willful misconduct of such Indemnitee. Debtor agrees
that upon written notice by any Indemnitee of any assertion that could give rise
to an expense, Debtor shall assume full responsibility for the defense thereof.
Each Indemnitee agrees to use its best efforts to promptly notify Debtor of any
such assertion of which such Indemnitee has knowledge.

         (b) Without limiting the application of Section 6.01(a), Debtor agrees
to pay, or reimburse Secured Party for (if Secured Party shall have incurred
fees, costs or expenses because Debtor shall have failed to comply with its
obligations under this Assignment or any other Credit Document), any and all
fees, costs and expenses of whatever kind or nature incurred in connection


                                       8
<PAGE>   138
 
with the creation, preservation or protection of Secured Party's Liens on, and
security interest in, the Collateral, including, without limitation, all fees
and taxes in connection with the recording or filing of instruments and
documents in public offices, payment or discharge of any taxes or Liens upon or
in respect of the Collateral, premiums for insurance with respect to the
Collateral and all other fees, costs and expenses in connection with protecting,
maintaining or preserving the Collateral and Secured Party's interest therein,
whether through judicial proceedings or otherwise, or in defending or
prosecuting any actions, suits or proceedings arising out of or relating to the
Collateral.

         (c) Without limiting the application of Section 6.01(a) or (b), Debtor
agrees to pay, indemnify and hold each Indemnitee harmless from and against any
expenses which such Indemnitee may suffer, expend or incur in consequence of or
growing out of any misrepresentation by Debtor in this Agreement or any of the
other Credit Documents or in any statement or writing contemplated by or made or
delivered pursuant to or in connection with this Agreement or any of the other
Credit Documents.

         (d) If and to the extent that the obligations of Debtor under this
Section 6.01 are unenforceable for any reason, Debtor hereby agrees to make the
maximum contribution to the payment and satisfaction of such obligations which
is permissible under applicable law.

         6.02. Indemnity Obligations Secured by Collateral; Survival. Any
amounts paid by any Indemnitee as to which such Indemnitee has the right to
reimbursement shall constitute Obligations secured by the Collateral. The
indemnity obligations of Debtor contained in this Article VIII shall continue in
full force and effect notwithstanding the full payment of the Note and all of
the other Obligations and notwithstanding the discharge thereof.

                             SECTION 7. DEFINITIONS

                               SUBSIDIARY GUARANTY

         GUARANTY dated as of December 1, 1998 (as amended, modified or
 supplemented from time to time, this "Guaranty"), made by the undersigned (the
"Guarantor").


                              W I T N E S S E T H :


         WHEREAS, EOTT Energy Operating Limited Partnership (the "Borrower") and
Enron Corp., an Oregon corporation (the "Lender") have entered into an Amended
and Restated Credit Agreement, dated as of December 1, 1998 (as amended,
modified or supplemented from time to time, the "Credit Agreement"; except as
otherwise defined herein, terms used herein and defined in the Credit Agreement
shall be used herein as therein defined), providing for the making of Loans to
the Borrower and the issuance of, and participation in, Letters of Credit and
Guarantees for the account of the Borrower and its Subsidiaries, all as
contemplated therein;

         WHEREAS, the Guarantor is a 99% owned Subsidiary of the Borrower;

         WHEREAS, it is a condition to the making of Loans under the Credit
Agreement and the issuance of Letters of Credit and Guarantees that the
Guarantor shall have executed and delivered this Guaranty; and

         WHEREAS, the Guarantor will obtain benefits from the incurrence of
Loans by the Borrower under the Credit Agreement and the issuance of Letters of
Credit and Guarantees and, accordingly, desires to execute this Guaranty in
order to satisfy the conditions described in the preceding paragraph and to
induce the Lender to make Loans to the Borrower and issue Letters of Credit and
Guarantees.

         NOW, THEREFORE, in consideration of the foregoing and other benefits
accruing to the Guarantor, the receipt and sufficiency of which are hereby
acknowledged, the Guarantor hereby makes the following representations and
warranties to the Lender and hereby covenants with the Lender as follows:

         1. The Guarantor irrevocably and unconditionally guarantees: (i) the
full and prompt payment when due (whether at the stated maturity, by
acceleration or otherwise) of (w) the principal of and interest on the Notes
issued by, and the Loans made to, the Borrower under the Credit Agreement (x)
the Letter of Credit Outstandings and the Guarantee Outstandings and (y) all
other obligations (including obligations which, but for the automatic stay under
Section 362(a) of the Bankruptcy Code, would become due) and liabilities owing
by the Borrower to the Lender under the Credit Agreement (including, without
limitation, indemnities, fees and interest thereon) whether now existing or
hereafter incurred under, arising out of or in connection with the Credit
Agreement or any other Credit Document and the due performance and compliance
with the terms of the Credit Documents by the Borrower (all such principal,
interest, liabilities and obligations being herein collectively called the
"Guaranteed Obligations"); provided that the maximum amount payable by the
Guarantor hereunder shall at no time exceed the Maximum Amount (as hereinafter
defined) of 


<PAGE>   153

the Guarantor. As used herein, "Maximum Amount" of the Guarantor means an amount
equal to 90% of the amount by which (i) the present fair saleable value of the
Guarantor's assets exceeds (ii) the amount reasonably expected to come due in
respect of liabilities, other than contingent liabilities of the Guarantor
hereunder, in each case determined on the Initial Credit Event Date or on the
day any demand is made under this Guaranty, whichever date results in a higher
Maximum Amount. Subject to the proviso in the second preceding sentence, the
Guarantor understands, agrees and confirms that the Lender may enforce this
Guaranty up to the full amount of the Guaranteed Obligations against the
Guarantor without proceeding against any other Subsidiary Guarantor, the
Borrower, against any security for the Guaranteed Obligations, or under any
other guaranty covering all or a portion of the Guaranteed Obligations. All
payments by the Guarantor under this Guaranty shall be made on the same basis as
payments by the Borrower under Section 6 of the Credit Agreement. (All payments
received by the Lender pursuant to this Guaranty shall be applied in the manner
set forth in Section 5.04 of the Security Agreements.)

         2. Additionally, the Guarantor unconditionally and irrevocably,
guarantees the payment of any and all Guaranteed Obligations of the Borrower to
the Lender whether or not due or payable by the Borrower upon the occurrence in
respect of the Borrower of any of the events specified in Section 11.05 of the
Credit Agreement, and unconditionally and irrevocably, jointly and severally,
promises to pay such Guaranteed Obligations to the Lender, or order, on demand,
in lawful money of the United States.

         3. The liability of the Guarantor hereunder is exclusive and
independent of any security for or other guaranty of the indebtedness of the
Borrower whether executed by the Guarantor, any other Guarantor, any other
guarantor or by any other party, and the liability of the Guarantor hereunder
shall not be affected or impaired by (a) any direction as to application of
payment by the Borrower or by any other party, (b) any other continuing or other
guaranty, undertaking or maximum liability of a guarantor or of any other party
as to the indebtedness of the Borrower, (c) any payment on or in reduction of
any such other guaranty or undertaking, (d) any dissolution, termination or
increase, decrease or change in personnel by the Borrower or (e) any payment
made to the Lender on the indebtedness which the Lender repays the Borrower
pursuant to court order in any bankruptcy, reorganization, arrangement,
moratorium or other debtor relief proceeding, and the Guarantor waives any right
to the deferral or modification of its obligations hereunder by reason of any
such proceeding.

         4. The obligations of the Guarantor hereunder are independent of the
obligations of any other Subsidiary Guarantor, any other guarantor or the
Borrower, and a separate action or actions may be brought and prosecuted against
the Guarantor whether or not action is brought against any other Subsidiary
Guarantor, any other guarantor or the Borrower and whether or not any other
Subsidiary Guarantor, any other guarantor of the Borrower or the Borrower be
joined in any such action or actions. The Guarantor waives, to the fullest
extent permitted by law, the benefit of any statute of limitations affecting its
liability hereunder or the enforcement thereof. Any payment by the Borrower or
other circumstance which operates to toll any statute of limitations as to the
Borrower shall operate to toll the statute of limitations as to the Guarantor.

         5. The Guarantor hereby waives notice of acceptance of this Guaranty
and notice of any liability to which it may apply, and waives promptness,
diligence, presentment, demand of 


                                       2
<PAGE>   154

payment, protest, notice of dishonor or nonpayment of any such liabilities, suit
or taking of other action by the Lender against, and any other notice to, any
party liable thereon (including the Guarantor or any other guarantor or the
Borrower).

         6. The Lender may (except as shall be required by applicable statute
and cannot be waived) at any time and from time to time without the consent of,
or notice to, the Guarantor, without incurring responsibility to the Guarantor,
without impairing or releasing the obligations of the Guarantor hereunder, upon
or without any terms or conditions and in whole or in part:

         (a) change the manner, place or terms of payment of, and/or change or
     extend the time of payment of, renew or alter, any of the Guaranteed
     Obligations, any security therefor, or any liability incurred directly or
     indirectly in respect thereof, and the guaranty herein made shall apply to
     the Guaranteed Obligations as so changed, extended, renewed or altered;

         (b) sell, exchange, release, surrender, realize upon or otherwise deal
     with in any manner and in any order any property by whomsoever at any time
     pledged or mortgaged to secure, or howsoever securing, the Guaranteed
     Obligations or any liabilities (including any of those hereunder) incurred
     directly or indirectly in respect thereof or hereof, and/or any offset
     there against;

         (c) exercise or refrain from exercising any rights against the Borrower
     or others or otherwise act or refrain from acting;

         (d) settle or compromise any of the Guaranteed Obligations, any
     security therefor or any liability (including any of those hereunder)
     incurred directly or indirectly in respect thereof or hereof, and may
     subordinate the payment of all or any part thereof to the payment of any
     liability (whether due or not) of the Borrower to creditors of the
     Borrower;

         (e) apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of the Borrower to the Lender regardless of what
     liabilities of the Borrower remain unpaid;

         (f) consent to or waive any breach of, or any act, omission or default
     under, any of the Credit Documents or any of the instruments or agreements
     referred to therein, or otherwise amend, modify or supplement any of the
     Credit Documents or any of such other instruments or agreements; and/or

         (g) act or fail to act in any manner referred to in this Guaranty which
     may deprive the Guarantor of its right to subrogation against the Borrower
     to recover full indemnity for any payments made pursuant to this Guaranty.

         7. No invalidity, irregularity or unenforceability of all or any part
of the Guaranteed Obligations or of any security therefor shall affect, impair
or be a defense to this Guaranty, and this Guaranty shall be primary, absolute
and unconditional notwithstanding the occurrence of any event or the existence
of any other circumstances which might constitute a legal or equitable discharge
of a surety or guarantor except payment in full of the Guaranteed Obligations.


                                       4
<PAGE>   155

 
         8. This Guaranty is a continuing one and all liabilities to which it
applies or may apply under the terms hereof shall be conclusively presumed to
have been created in reliance hereon. No failure or delay on the part of the
Lender in exercising any right, power or privilege hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
expressly specified are cumulative and not exclusive of any rights or remedies
which the Lender would otherwise have. No notice to or demand on the Guarantor
in any case shall entitle the Guarantor to any other further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Lender to any other or further action in any circumstances without notice or
demand. It is not necessary for the Lender to inquire into the capacity or
powers of the Borrower or any of its Subsidiaries or the officers, directors,
partners or agents acting or purporting to act on its behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

         9. Any indebtedness of the Borrower now or hereafter held by the
Guarantor is hereby subordinated to the indebtedness of the Borrower to the
Lender; and such indebtedness of the Borrower to the Guarantor, if the Lender,
after an Event of Default has occurred, so requests, shall be collected,
enforced and received by the Guarantor as trustee for the Lender and be paid
over to the Lender on account of the indebtedness of the Borrower to the Lender,
but without affecting or impairing in any manner the liability of the Guarantor
under the other provisions of this Guaranty. Prior to the transfer by the
Guarantor of any note or negotiable instrument evidencing any indebtedness of
the Borrower to the Guarantor, the Guarantor shall mark such note or negotiable
instrument with a legend that the same is subject to this subordination.

         10. (a) The Guarantor waives any right (except as shall be required by
applicable statute and cannot be waived) to require the Lender to: (i) proceed
against the Borrower, any other Guarantor, any other guarantor of the Borrower
or any other party; (ii) proceed against or exhaust any security held from the
Borrower, any other Guarantor, any other guarantor of the Borrower or any other
party; or (iii) pursue any other remedy in the Lender's power whatsoever. The
Guarantor waives any defense based on or arising out of any defense of the
Borrower, any other Guarantor, any other guarantor of the Borrower or any other
party other than payment in full of the Guaranteed Obligations, including,
without limitation, any defense based on or arising out of the disability of the
Borrower, any other Guarantor, any other guarantor of the Borrower or any other
party, or the unenforceability of the Guaranteed Obligations or any part thereof
from any cause, or the cessation from any cause of the liability of the Borrower
other than payment in full of the Guaranteed Obligations. The Lender may, at its
election, foreclose on any security held by the Lender by one or more judicial
or nonjudicial sales, whether or not every aspect of any such sale is
commercially reasonable (to the extent such sale is permitted by applicable
law), or exercise any other right or remedy the Lender may have against the
Borrower or any other party, or any security, without affecting or impairing in
any way the liability of the Guarantor hereunder except to the extent the
Guaranteed Obligations have been paid in full. The Guarantor waives any defense
arising out of any such election by the Lender, even though such election
operates to impair or extinguish any right of reimbursement or subrogation or
other right or remedy of the Guarantor against the Borrower or any other party
or any security.


                                       5
<PAGE>   156

         (b) The Guarantor waives all presentments, demands for performance,
protests and notices, including, without limitation, notices of nonperformance,
notices of protest, notices of dishonor, notices of acceptance of this Guaranty,
and notices of the existence, creation or incurring of new or additional
indebtedness. The Guarantor assumes all responsibility for being and keeping
itself informed of the Borrower's financial condition and assets, and of all
other circumstances bearing upon the risk of nonpayment of the Guaranteed
Obligations and the nature, scope and extent of the risks which the Guarantor
assumes and incurs hereunder, and agrees that the Lender shall have no duty to
advise the Guarantor of information known to them regarding such circumstances
or risks.

         (c) Except as otherwise provided in clause (d) below, the Guarantor
hereby waives all rights of subrogation which it may at any time otherwise have
as a result of this Guaranty (whether contractual, under Section 509 of the
Bankruptcy Code, or otherwise) to the claims of the Lender against the Borrower,
and all contractual, statutory or common law rights of reimbursement,
contribution or indemnity from the Borrower which it may at any time otherwise
have as a result of this Guaranty. The Guarantor hereby further waives any right
to enforce any other remedy which the Lender now have or may hereafter have
against the Borrower, any endorser or any other guarantor of all or any part of
the Guaranteed Obligations and any benefit of, and any right to participate in,
any security or collateral given to or for the benefit of the Lender to secure
payment of the Guaranteed Obligations.

         11. The Lender agrees that this Guaranty may not be enforced against
any director, officer, employee, or stockholder of the Guarantor (except to the
extent such stockholder is also a Guarantor hereunder). This Agreement is
non-recourse to the General Partner as provided in Section 12.15 of the Credit
Agreement.

         12. In order to induce the Lender to make Loans and issue Letters of
Credit, Letters of Indemnity and Guarantees pursuant to the Credit Agreement,
the Guarantor represents, warrants and covenants that:

         (a) The Guarantor (i) is a duly formed and validly existing limited
     partnership under the laws of the jurisdiction of its formation, and has
     the power and authority to own its property and assets and to transact the
     business in which it is engaged and presently proposes to engage and (ii)
     is duly qualified and is authorized to do business and is in good standing
     in all jurisdictions where it is required to be so qualified and where the
     failure to be so qualified could reasonably be expected to have a Material
     Adverse Effect.

         (b) The Guarantor has the power and authority to execute, deliver and
     carry out the terms and provisions of this Guaranty and each other Credit
     Document to which it is a party and has taken all necessary corporate
     action to authorize the execution, delivery and performance by it of each
     such Credit Document. The Guarantor has duly executed and delivered this
     Guaranty, and each other Credit Document to which it is a party and each
     such Credit Document constitutes the legal, valid and binding obligation of
     the Guarantor enforceable in accordance with its terms, except to the
     extent that the enforceability hereof may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium or other 


                                       6
<PAGE>   157

     similar laws affecting creditors' rights generally and by equitable
     principles (regardless of whether enforcement is sought in equity or at
     law).

         (c) Neither the execution, delivery or performance by the Guarantor of
     this Guaranty or any other Credit Document to which it is a party, nor
     compliance by it with the terms and provisions hereof (i) will contravene
     any applicable provision of any law, statute, rule or regulation, or any
     order, writ, injunction or decree of any court or governmental
     instrumentality, (ii) will conflict or be inconsistent with or result in
     any breach of, any of the terms, covenants, conditions or provisions of, or
     constitute a default under, or (other than pursuant to the Security
     Documents) result in the creation or imposition of (or the obligation to
     create or impose) any Lien upon any of the property or assets of the
     Guarantor or any of its Subsidiaries pursuant to the terms of any
     indenture, mortgage, deed of trust, loan agreement, credit agreement or
     other material agreement or other instrument to which the Guarantor or any
     of its Subsidiaries is a party or by which it or any of its property or
     assets is bound or to which it may be subject or (iii) will violate any
     provision of the certificate of limited partnership or the partnership
     agreement of the Guarantor or any of its Subsidiaries.

         (d) No order, consent, approval, license, authorization or validation
     of, or filing, recording or registration with, or exemption by, any
     governmental or public body or authority, or any subdivision thereof, is
     required to authorize, or is required in connection with, (i) the
     execution, delivery and performance of this Guaranty or any other Credit
     Document to which the Guarantor is a party, or (ii) the legality, validity,
     binding effect or enforceability of this Guaranty or any other Credit
     Document to which the Guarantor is a party.

         (e) There are no actions, suits or proceedings pending or threatened
     (i) with respect to the Guarantor that could reasonably be expected to have
     a Material Adverse Effect or (ii) that could reasonably be expected to have
     a material adverse effect on the rights or remedies of the Lender or on the
     ability of the Guarantor to perform its respective obligations to the
     Lender hereunder and under the other Credit Documents to which it is a
     party.

         13. The Guarantor covenants and agrees that on and after the date
hereof and until the termination of the Total Commitment and when neither the
Note, any Letter of Credit or Guarantee remains outstanding and all Guaranteed
Obligations have been paid in full, the Guarantor shall take, or will refrain
from taking, as the case may be, all actions that are necessary to be taken or
not taken so that no violation of any provision, covenant or agreement contained
in Section 9 or 10 of the Credit Agreement, and so that no Default or Event of
Default, is caused by the actions of the Guarantor or any of its Subsidiaries.

         14. The Guarantors hereby jointly and severally agree to pay all
out-of-pocket costs and expenses of the Lender in connection with the
enforcement of this Guaranty and any amendment, waiver or consent relating
hereto (including, without limitation, the fees and disbursements of counsel
(including in-house counsel) employed by the Lender).


                                       6
<PAGE>   158

         15. This Guaranty shall be binding upon the Guarantor and its
successors and assigns and shall inure to the benefit of the Lender and its
successors and assigns.

         16. Neither this Guaranty nor any provision hereof may be changed,
waived, discharged or terminated except with the written consent of the
Guarantor and the Lender at all times prior to the time on which all Obligations
have been paid in full.

         17. The Guarantor acknowledges that an executed (or conformed) copy of
each of the Credit Documents has been made available to its principal executive
officers and such officers are familiar with the contents thereof.

         18. In addition to any rights now or hereafter granted under applicable
law and not by way of limitation of any such rights, upon the occurrence and
during the continuance of an Event of Default (such term to mean and include any
"Event of Default" as defined in the Credit Agreement continuing after any
applicable grace period), the Lender is hereby authorized at any time or from
time to time, without notice to the Guarantor or to any other Person, any such
notice being expressly waived, to set off and to appropriate and apply any and
all deposits (general or special) and any other indebtedness at any time held or
owing by the Lender to or for the credit or the account of the Guarantor,

                             CONTRIBUTION AGREEMENT

                CONTRIBUTION AGREEMENT, dated as of December 1, 1998 (as
amended, modified or supplemented from time to time, the "Contribution
Agreement"), among EOTT Energy Operating Limited Partnership (the "Borrower")
and each of its Subsidiaries (as defined in the Credit Agreement referred to
below) listed on the signature pages hereto (each a "Guarantor" and together
with any other entity that becomes a party hereto pursuant to Section II
hereof, the "Guarantors"). As used herein, the term "Contributor" shall mean
the Borrower and each of the Guarantors required to make any payment to any
other Guarantor pursuant to Section 1 of this Contribution Agreement. Except as
otherwise defined herein, capitalized terms used herein and not otherwise
defined shall have the meaning assigned to those terms in the Credit Agreement.

                                  WITNESSETH:

                WHEREAS, the Borrower and Enron Corp. (the "Lender") have
entered into an Amended and Restated Credit Agreement, dated as of December 1,
1998 (as amended, modified or supplemented from time to time, the "Credit
Agreement"), providing for the making of Loans to the Borrower and the issuance
of by order Letters of Credit of the Borrower and its Subsidiaries and the
issuance of Guarantees, all as contemplated therein;

                WHEREAS, it is a condition to the making of Loans to the
Borrower and the issuance of Letters of Credit under the Credit Agreement that
each Guarantor shall have executed and delivered a Subsidiary Guaranty;

                WHEREAS, each Guarantor will obtain benefits from the
incurrence of Loans by the Borrower, and the issuance of by order Letters of
Credit of the Borrower and its Subsidiaries under the Credit Agreement and,
accordingly, each Guarantor has executed and delivered a Subsidiary Guaranty in
order to satisfy the condition described in the preceding paragraph and to
induce the Lender to make Loans to the Borrower and issue Letters of Credit ;

                WHEREAS, pursuant to the Subsidiary Guaranties, each of the
Guarantors has agreed unconditionally and irrevocably, and jointly and
severally, to guaranty as primary obligor and not merely as surety the
Guaranteed Obligations (as defined in each Subsidiary Guaranty); and

                WHEREAS, the Contributors wish to enter into this Contribution
Agreement to effect an equitable sharing of the Guaranteed Obligations;

                NOW THEREFORE, in consideration of the premises and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                I . CONTRIBUTION. At any time a payment in respect of the
Guaranteed Obligations is made under a Subsidiary Guaranty, the right of
contribution, if any, of each Guarantor against each Contributor shall be
determined as provided in the immediately following sentence, with the right
of contribution of each Guarantor to be revised and restated as of each date



<PAGE>   162


on which a payment (a "Relevant Payment") is made on the Guaranteed Obligations
under the Subsidiary Guaranty. At any time that a Relevant Payment is made by a
Guarantor that results in the aggregate payments made by such Guarantor in
respect of the Guaranteed Obligations to and including the date of the Relevant
Payment exceeding such Guarantor's Contribution Percentage (as defined below)
of the aggregate payments made by all Guarantors in respect of the Guaranteed
Obligations to and including the date of the Relevant Payment (such excess, the
"Aggregate Excess Amount"), each such Guarantor shall have a right of
contribution (i) against the Borrower and (ii) against each Contributor who has
made payments in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment in an aggregate amount less than such
Contributor's Contribution Percentage of the aggregate payments made to and
including the date of the Relevant Payment by all Guarantors in respect of the
Guaranteed Obligations (the aggregate amount of such deficit, the "Aggregate
Deficit Amount") in an amount equal to (x) a fraction the numerator of which is
the Aggregate Excess Amount of such Guarantor and the denominator of which is
the Aggregate Excess Amount of all Guarantors multiplied by (y) the Aggregate
Deficit Amount of such Contributor. A Guarantor's right of contribution, if
any, pursuant to the preceding sentences shall arise at the time of each
computation, subject to adjustment to the time of.any subsequent computation;
provided, that no Guarantor may take any action to enforce such right until the
Guaranteed Obligations have been paid in full and the Total Commitment has been
terminated, it being expressly recognized and agreed by all parties hereto that
any Guarantor's right of contribution arising pursuant to this Contribution
Agreement against any Contributor shall be expressly junior and subordinate to
such Contributor's obligations and liabilities in respect of the Guaranteed
Obligations and any other obligations owing under the Subsidiary Guaranty. As
used in this Contribution Agreement: (i) each Contributor's "Contribution
Percentage" shall mean the percentage obtained by dividing (x) the Adjusted Net
Worth (as defined below) of such Contributor by (y) the aggregate Adjusted Net
Worth of all Guarantors; (ii) the "Adjusted Net Worth" of each Guarantor shall
mean the greater of (x) the Net Worth (as defined below) of such Guarantor and
(y) zero; and (iii) the "Net Worth" of each Guarantor shall mean the amount by
which the fair salable value of such Guarantor's assets on the Initial Credit
Event Date (or, in the case of a Guarantor that becomes a party hereto after
the Initial Credit Event Date, on the date such Guarantor becomes a party
hereto) exceeds its existing debts and other liabilities (including contingent
liabilities, but without giving effect to any Guaranteed Obligations arising
under the Subsidiary Guaranty), in each case after giving effect to the
Transaction and all other transactions occurring on the Initial Credit Event
Date.

                2. NO OTHER CONTRIBUTION OR SUBROGATION RIGHTS. All parties
hereto recognize and agree that, except for any right of contribution arising
pursuant to Section 1, each Guarantor who makes any payment in respect of the
Guaranteed Obligations shall have no right of contribution or subrogation
against any other Guarantor in respect of such payment, any such right of
contribution or subrogation arising under law or otherwise being expressly
waived by all Guarantors.

                3. CONTRIBUTION RIGHT AS AN ASSET. Each of the Guarantors
recognizes and acknowledges that the rights to contribution arising hereunder
shall constitute an asset in favor of the party entitled to such contribution.
In this connection, each Guarantor has the right to waive its contribution
right against any Guarantor to the extent that after giving effect to such
waiver such Guarantor would remain solvent, in the determination of the Lender.

                                       2



<PAGE>   163



                4. AMENDMENT OR WAIVER. Any provision of this Agreement may
be amended or waived if, but only if, such amendment or waiver is in writing
and is signed by the parties hereto and consented to by the Lender.

                5. BENEFIT OF AGREEMENT. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. To the extent any such successor shall be a
successor to all or part of the assets of a Guarantor, such successor shall
also constitute a Guarantor, with a Contribution Percentage equal to the
Contribution Percentage of the predecessor corporation or as otherwise
consented to by the Lender.

                6. PRESERVATION OF RIGHTS. This Agreement shall not limit any
right which any Guarantor may have against any other Person which is not a
party hereto.

                7. TERMINATION: RELEASE. (a) This Agreement, as it may be
amended, supplemented or otherwise modified from time to time, shall remain in
effect and shall not be terminated as to any Guaranteed Obligation until such
Guaranteed Obligation has been discharged or otherwise satisfied in accordance
with the laws of the State of Texas.

                (b) On the date on which any Guarantor is released from its
obligations under the Subsidiary Guaranty, such Guarantor shall also be
released without any further action from the provisions of this Agreement.

                8. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

                9. COUNTERPARTS. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

                10. EFFECTIVENESS. This Agreement shall become effective upon
execution hereof by each such party and delivery of executed counterparts
hereof by them to the Lender.

                11. ADDITIONAL GUARANTORS. At the time any entity first becomes
a Subsidiary Guarantor after the Initial Credit Event Date, it shall upon
execution of a counterpart hereof become a Guarantor for all purposes of this
Agreement.

         SECTION 2.  AMOUNT AND TERMS OF CREDIT.

         2.01 The Loans. Subject to and upon the terms and conditions set forth

on the Effective Date the Lender shall make available the amount of the Loans by
depositing such amounts to the Borrower's account at the Disbursement Office in
immediately available funds.

         2.03 Notes. (a) The Borrower's obligation to pay the principal of, and
interest on, the Loans shall be evidenced by a Tranche A promissory note and a
Tranche B promissory note duly executed and delivered by the Borrower

         (b) Overdue principal and, to the extent permitted by law, overdue
interest in respect of the Loans shall bear interest at a rate per annum equal
to the Base Rate in effect from time to time plus 2%; provided, however, that

2% plus the rate of interest applicable thereto at maturity.

         (c) Accrued interest shall be payable monthly in respect of the Loans
no later than the fifth Business Day of the month immediately following the

         SECTION 3. PAYMENTS.

         3.01 Method and Place of Payment. Except as otherwise specifically
provided herein, all payments under this Agreement or the Notes shall be made to
the Lender not later than 1:00 P.M. (Houston, Texas time) on the date when due
and shall be made in Dollars in immediately available funds at the Payment
Office of the Lender. Whenever any payment to be made hereunder or under the
Notes shall be stated to be due on a day which is not a Business Day, the due
date thereof shall be extended to the next succeeding Business Day (unless such
next succeeding Business Day is after the Maturity Date, in which event the due
date shall be the immediately preceding Business Day) and, with respect to
payments of principal, interest shall be payable at the applicable rate during
such extension.

         3.02 Net Payments; Taxes. (a) All payments required to be made by the
Borrower hereunder, under the Notes or any other Credit Document, will be made
without setoff, counterclaim or other defense. All such payments will be made
free and clear of, and without deduction or withholding for, any present or
future taxes, levies, imposts, duties, fees, assessments, deductions or other
charges of whatever nature, now or hereafter existing, levied, imposed or
asserted to be due by any jurisdiction or by any political subdivision or taxing
authority thereof or therein and all interest, penalties or other liabilities
with respect thereto (collectively, "Taxes"), but excluding from the provisions
of this sentence any tax imposed on or measured by the net income of the Lender
pursuant to the laws of the jurisdiction in which such Lender is organized or in
which the principal office of Lender is located (its "Home Jurisdiction"). If
any Taxes (other than any Taxes imposed on or measured by the net income of the
Lender pursuant to the laws of its Home Jurisdiction) are levied or imposed or
asserted to be due by way of deduction or withholding, the Borrower agrees (i)
to pay the full amount of such Taxes, and such additional amounts as may be
necessary so that every payment of all amounts due hereunder and amounts payable
under the Notes and under any other Credit Document, after withholding or
deduction for or on account of all Taxes (including, without limitation,
deductions and withholdings applicable to such additional sums), will not be
less than the amount provided for herein and in each such Note and other Credit
Document; and (ii) the Borrower shall duly and timely pay the full amount
deducted and withheld to the relevant taxing authority or other authority in
accordance with applicable law. If any amounts are payable pursuant to the
preceding sentence, the Borrower shall also pay the Lender, upon the written
request of the Lender, such additional amounts as may be necessary so that the
amount received pursuant to the preceding sentence, after subtracting all Taxes
(including, without limitation, withholding taxes and taxes on or measured by
net income) imposed by any jurisdiction (including the Lender's Home
Jurisdiction), in respect of the receipt or accrual of Taxes and other amounts
paid or payable to or on behalf of the Lender pursuant to the preceding sentence
and this sentence, shall equal such Taxes indemnified against pursuant to the
preceding sentence, all as determined by the Lender in its reasonable
discretion. For purposes of this Section 3.02, the term "Lender" shall (without
limitation) include any person who, for purposes of the relevant laws imposing
any Taxes, is treated as a successor or assign in interest of all or any portion
of an interest in any Credit Documents, whether such person acquires such
interest pursuant to a participation or otherwise and whether or not such person
is a registered assign.

         (b) In addition, the Borrower will indemnify and hold harmless the
Lender for the amount of any Taxes incurred in respect of or as a result of any
payments made or required to be made hereunder, under the Notes or other Credit
Document or the execution, delivery, transfer of or any 



                                       12
<PAGE>   17


other event or matter in respect of all or any portion of or any interest in any
such agreement or document, of any nature whatsoever that are levied, imposed or
asserted to be due by any jurisdiction or by any political subdivision or taxing
authority thereof or therein and paid by the Lender, but excluding from the
provisions of this sentence any tax imposed on or measured by the net income of
the Lender pursuant to the laws of its Home Jurisdiction. If any such Taxes are
paid by the Lender, the Borrower will pay the Lender the full amount of such
Taxes, and such additional amounts as may be necessary so that the amount
received pursuant to this sentence, after reduction for all Taxes (including,
without limitation, withholding taxes and taxes imposed on or measured by net
income) incurred as a result of the receipt or accrual of the amounts payable
pursuant to this sentence under the laws of all such jurisdictions and political
subdivisions and taxing authorities (including the Lender's Home Jurisdiction),
shall equal the amount of such Taxes paid by the Lender, together with interest
thereon at the overdue interest rate provided in Section 2.04(b). The Lender
agrees that it shall notify the Borrower of any notice of deficiency, proposed
adjustment or other written claim by a taxing authority with respect to a Tax
for which the Borrower is obligated to indemnify the Lender pursuant to this
Section 3.02(b); provided, however, that the Lender's failure to provide such
notice shall in no way affect the obligation of the Borrower to indemnify the
Lender pursuant to this Section 3.02. Payments by the Borrower pursuant to this
indemnification shall be made within 30 days from the date the Lender makes
written demand therefor, which demand shall be accompanied by a certificate
describing in reasonable detail the basis thereof.

         (c) The Borrower will furnish to the Lender within 30 days after the
date the payment of any Taxes, or any withholding or deduction on account
thereof, is due pursuant to applicable law certified copies of tax receipts, or
other evidence of payment sufficient to establish a deduction or foreign tax
credit with respect to such Taxes for the applicable Lender, evidencing such
payment by the Borrower.

other right, power or privilege hereunder or thereunder. The rights and remedies
herein expressly provided are cumulative and not exclusive of any rights or
remedies that the Lender would otherwise have. No notice to or demand on the
Borrower in any case shall entitle the Borrower to any other or further notice

of the Lender to any other or further action in any circumstances without notice
or demand.

         9.15 Interest. It is the intention of the parties hereto that the
Lender shall conform strictly to usury laws applicable to it. Accordingly, if
the transactions contemplated hereby would be usurious as to the Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to the Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (I) the aggregate of all
consideration which constitutes interest under law applicable to the Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by the Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by the Lender to the
Borrower); and (ii) in the event that the maturity of the Notes is accelerated
by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to the Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by the Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be
credited by the Lender on the principal amount of the Indebtedness (or, to the
extent that the principal amount of the Indebtedness shall have been or would
thereby be paid in full, refunded by the Lender to the Borrower). All sums paid
or agreed to be paid to the Lender for the use, forbearance or detention of sums
due hereunder shall, to the extent permitted by law applicable to the Lender, be
amortized, prorated, allocated and spread throughout the stated term of the
Loans evidenced by the Notes until payment in full so that the rate or amount of
interest on account of any Loans hereunder does not exceed the maximum amount
allowed by such applicable law. If at any time and from time to time (I) the
amount of interest payable to the Lender on any date shall be computed at the
Highest Lawful Rate applicable to the Lender pursuant to this Section 12.07 and
(ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to the Lender would be less than the amount of
interest payable to the Lender computed at the Highest Lawful Rate applicable to
the Lender, then the amount of interest payable to the Lender in respect of such
subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to the Lender until the total amount of interest
payable to such Lender shall equal the total amount of interest which would have
been payable to the Lender if the total amount of interest had been computed
without giving effect to this Section 12.07. To the extent that Article
5069-1D.003 of the Finance Code is relevant for the purpose of determining the
Highest Lawful Rate, the Lender elects to determine the applicable rate ceiling
under such Chapter by the indicated weekly rate ceiling form time to time in
effect.

         9.16 No Oral Agreements. THE CREDIT DOCUMENTS EMBODY THE ENTIRE
AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER
AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT
MATTER HEREOF AND THEREOF. THE CREDIT DOCUMENTS REPRESENT THE FINAL AGREEMENT

     8.24 Compliance With Environmental Laws



     (i)

              (1) Paramount Refinery and Lakewood Tank Farm

                  Environmental conditions exist in the area of the refinery
                  and associated tank farm, including soil and groundwater
                  contamination, that are the subject of ongoing, long-term
                  remediation. Additionally, environmental issues include
                  refinery compliance with both federal and state air
                  regulations. These site conditions have been well documented
                  in the following reports:

                  (a) 1990 Pilko & Associates Environmental Sire Assessment.

                  (b) February 1994 CET Environmental Services Revised
                      Estimated

                      Remediation Report.

                  (c) 1993 Chemical Waste Management, Inc. semi-annual refinery

                      groundwater monitoring report.

                  (d) January 1994 Radian Corporation Report for refinery air
                      compliance.

                  (e) The Prospectus dated March 18, 1994, relating to EOTT
                      Energy Partners, L.P.



              (2) 3-B Rattlesnake Refinery (Wickett, TX):

                  Environmental condition may exist in the area of the refinery
                  including soil and groundwater contamination. Additionally,
                  environmental issues include refinery compliance with both
                  federal and state solid wastes disposal regulations,
                  including failure to report unscheduled releases, and
                  possible OSHA asbestos removal violations. These site
                  conditions have been documented in the following reports:

                  (a) 1990 Esmond Engineering, Inc. Environmental Assessment 
                      Report.

                  (b) January 13, 1992, Texas Water Commission facility
                      inspection.

                  (c) May 15,1992, U.S. Environmental Protection Agency, Region
                      6 search warrant and subsequent inspection.

                  (d) The Prospectus dated March 18, 1994, relating to EOTT

                                                                          PAGE 2



              (3) Mid-America Refining Company (Chanute, KS):



                  (a) The environmental issues as described in the Prospectus
                      dated March 18, 1994, relating to EOTT Energy Partners, 
                      L.P.

      (ii)        See Schedule 5.11, Purchase & Sale Agreement by and between 
                  Koch Oil Company and Eott Energy Operating Limited 
                  Partnership.

     (iii)        None.

     (iv)         See 8.24 (a) (i) above. In addition:

                  (1) The Oil Pollution Act of 1990 (OPA) requires owners and
                      operators of "offshore facilities" to establish $150
                      million in financial responsibility to cover
                      environmental cleanup and restoration costs that may be
                      incurred in connection with an oil spill. On August 25,
                      1993, the MMS published an advanced notice of its
                      intention to adopt a rule under "OPA" that would define
                      "offshore facilities" to include all oil and gas
                      facilities that have the potential to affect the "waters
                      of the United States". Since EOTT owns and operates many
                      pipelines and tank batteries that could be the source of
                      a spill affecting the "waters of the United States," EOTT
                      could become subject to the financial responsibility rule
                      if it is adopted as proposed.

                  (2) All of those matters described in the Prospectus dated
                      March 18, 1994, relating to EOTT Energy Partners, L.P.

     (v)          None


     (vi)         None

Gentlemen:

         The parties have agreed to change the referenced Agreement as follows:

         For the time period of December 1, 1998 through March 31, 1999, Section
         2.1 shall be amended to change the first sentence to read as follows:

         "EOTT shall deliver and sell and Koch shall take delivery of and
         purchase [*] barrels per day ("bpd"), on average in each month, of
         Domestic Sweet Crude Oil as defined in Section 2.1(a) subject to the
         Adjusted Supply Volume requirements in Section 2.1(d)."

         Effective April 1, 1999, the language for this first sentence of
         Section 2.1 shall revert back to the language set forth in the original
         Agreement.

         Except as hereby amended, all other terms and conditions of the
