   Those statements in the Business and Properties discussion that are not
historical in nature should be deemed forward-looking statements that are
inherently uncertain. See "Forward-Looking Statements" in Management's
Discussion and Analysis of Financial Condition and Results of Operations in
the Company's 2000 Annual Report to Shareholders for a discussion of the
factors that could cause actual results to differ materially from those
projected.

General

   Sunoco, Inc.* was incorporated in Pennsylvania in 1971. It or its
predecessors have been active in the petroleum industry since 1886. Its
principal executive offices are located at 1801 Market Street, Philadelphia,
PA 19103-1699. Its telephone number is (215) 977-3000 and its Internet website
address is www.SunocoInc.com.

   The Company, through its subsidiaries, is principally a petroleum refiner
and marketer and chemicals manufacturer with interests in cokemaking. Sunoco's
petroleum refining and marketing operations include the manufacturing and
marketing of a full range of petroleum products, including fuels, lubricants
and petrochemical feedstocks, and the transportation of crude oil and refined
products. Sunoco's chemical operations comprise the manufacturing,
distribution and marketing of base commodity and intermediate petrochemicals.
The petroleum refining and marketing and chemicals operations are conducted
principally in the eastern half of the United States. Sunoco's cokemaking
operations are conducted in Virginia and Indiana.

   The Company's operations are organized into seven business units (Sun
Northeast Refining, Sunoco Northeast Marketing, Sunoco Chemicals, Sun
Lubricants, Sunoco MidAmerica Marketing & Refining, Sunoco Logistics and Sun
Coke) plus a holding company and a shared services organization. The
accompanying discussion of the Company's business and properties reflects this
organizational structure. For additional information regarding these business
units, see Management's Discussion and Analysis of Financial Condition and
Results of Operations in the Company's 2000 Annual Report to Shareholders.
Business segment information is also presented in Note 19 to the Consolidated
Financial Statements in the Company's 2000 Annual Report to Shareholders.

   Sunoco owns and operates five domestic refineries which are located in
Marcus Hook, PA, Philadelphia, PA, Toledo, OH, Tulsa, OK and Yabucoa, Puerto
Rico. The refineries in Marcus Hook, Philadelphia and Toledo produce
principally fuels and petrochemicals while the refineries in Tulsa and Puerto
Rico emphasize lubricants production with related fuels production being sold
in the wholesale market. The Puerto Rico refinery is subject to a plan of
disposition (see "Sun Lubricants" below). In addition, Sunoco owns and
operates a petrochemical facility in Philadelphia, PA, which produces phenol
and acetone, and is a joint venture partner in a facility in Marcus Hook which
produces propylene and polypropylene and in a facility in Mont Belvieu, TX,
which produces MTBE.

   Effective January 1, 2001, Sunoco completed the acquisition of Aristech
Chemical Corporation ("Aristech"), a wholly owned subsidiary of Mitsubishi
Corporation. Included in the acquisition are Aristech's five chemical plants
located at Neal, WV; Haverhill, OH; Neville Island, PA; and Pasadena and
LaPorte, TX and a research center in Pittsburgh, PA. These facilities have the
capacity to produce annually 1.5 billion pounds of propylene, over 1.6 billion
pounds of phenol and related derivatives (including bisphenol-A), and 800
million pounds of plasticizers.

   The following table sets forth certain consolidated information concerning
Sunoco's operations (in thousands of barrels daily). Additional information is

  Supply and Distribution

   Sunoco meets all of its crude oil requirements through purchases from third
parties. There has been an ample supply of crude oil available to meet
worldwide refining needs, and Sunoco has been able to supply its refineries
with the proper mix and quality of crude oils without disruption. Sunoco's
refineries processed approximately 80 percent light sweet crude oil during
2000. The Company believes that ample supplies of light sweet crude oil will
continue to be available. The following table sets forth Sunoco's net sources
of crude oil (in percentages):

 *Represents Sunoco's capacity to upgrade low-value petroleum products into
 higher-value products through catalytic cracking.
**Petrochemical feedstocks are utilized by the Sunoco Chemicals business to
 produce petrochemicals at these facilities. (See "Sunoco Chemicals" below.)

   During 2000, the Marcus Hook refinery had a scheduled turnaround of a 98
thousand barrels-per-day catalytic cracking unit. Other associated processing
units, including a gas plant, the alkylation unit and an 85 thousand barrels-
per-day crude unit were also shut down for scheduled maintenance during this
period. The turnaround was completed in a record 29 days. In September 2000, a
fire at the Philadelphia refinery resulted in the three-week shutdown of a 130
thousand barrels-per-day crude unit. A four-week scheduled maintenance
turnaround was also performed on this unit.

   During 1999, input to the crude units was voluntarily cut back in response
to the low margin environment. As a result, production of low-value products
was reduced without limiting production of high-value products from the
catalytic cracking units. Catalytic cracking utilization was higher in 1999
versus 1998 primarily due to the absence of any shutdowns in 1999. The
Philadelphia refinery had one planned and one unplanned catalytic cracker
shutdown during 1998. The most significant of this downtime was at a 73
thousand barrels-per-day unit at this facility. It included a 29-day shutdown
due to an emergency power interruption by the local utility and related start-
up problems and a subsequent scheduled six-week turnaround and modernization
of the unit. Scheduled maintenance activity during 1998 also included a 23-day
turnaround of the 200 thousand barrels-per-day crude unit at the Philadelphia
refinery.

   During 1999, Sun Northeast Refining completed numerous fuel recovery
projects at the Philadelphia refinery. The improvements made have enabled the
upgrade of products previously used as refinery fuel into higher value
products.

   Total fuels products sold to third parties at wholesale by Sun Northeast
Refining in 2000 were 335.4 thousand barrels daily compared to 365.6 thousand
barrels daily in 1999 and 353.8 thousand barrels daily in 1998. Sales to other
Sunoco business units by Sun Northeast Refining (primarily gasoline, middle
distillates and chemical feedstocks) totalled 204.0, 197.5 and 186.1 thousand
barrels daily in 2000, 1999 and 1998, respectively.

   Sunoco's Philadelphia and Marcus Hook refineries are connected by pipeline,
barge, truck and rail. An inter-refinery pipeline enables the transfer of
unfinished stocks, including butanes, naphtha, distillate blendstocks and
gasoline blendstocks. Finished products are delivered to customers via
Sunoco's pipeline and terminal network, third-party pipelines and barges.

   During the fourth quarter of 1999, Sun Northeast Refining entered into an
agreement with a subsidiary of FPL Energy ("FPL") to purchase steam from a
725-megawatt, natural gas fired cogeneration power plant to be constructed,
owned and operated by FPL at Sunoco's Marcus Hook refinery. Steam supplied by
the power plant will reduce the refinery's steam supply costs. It is
anticipated that construction will commence during 2001.

 Sunoco Northeast Marketing

   The Sunoco Northeast Marketing business consists of the retail sale of
gasoline and middle distillates and the operation of convenience stores in the
eastern United States. These activities are conducted primarily in a 13-state
region from Maine through Tennessee, with the highest concentration of outlets
in Connecticut, Massachusetts, New Jersey, New York, Pennsylvania and Rhode
Island. (See "MidAmerica Marketing & Refining" below for a discussion of
similar operations conducted in the midwestern U.S.)

 *Gasoline throughput per Company owned or leased outlet averaged 110.8, 109.6
 and 103.8 thousands of gallons monthly during 2000, 1999 and 1998,
 respectively. The improvement during the 1998-2000 period is consistent with
 Sunoco Northeast Marketing's goal of increasing gasoline throughput per
 outlet.
**Primarily traditional outlets.

   Sunoco Northeast Marketing's portfolio of outlets is designed to provide
optimal profit potential in each of its marketing areas. Sites differ in
various ways including: product distribution to the outlets; site ownership
and operation; and types of products and services provided.

   Direct outlets are sites at which Sunoco fuel products are delivered
directly to the site by Sunoco or its contract carriers. Investment in the
property, through ownership or lease, may be held by either the Company or an
independent dealer. These sites may be traditional locations that sell almost
exclusively fuel products or may include APlus(R) convenience stores or Ultra
Service Centers sm that provide automotive diagnosis and repair. Included
among Sunoco Northeast Marketing's outlets at December 31, 2000 were 55
outlets on limited access highways in Pennsylvania, New Jersey, New York and
Maryland. Of these outlets, 38 were company-operated sites providing gasoline,
diesel fuel and convenience store merchandise.

   Distributor outlets are sites in which the distributor takes delivery at a
terminal where Sunoco(R) products are available. Although these sites market
under the Sunoco(R) brand, Sunoco does not own, lease or operate the
locations.

   Sunoco Northeast Marketing typically offers four grades of gasoline at its
retail locations, consisting of Ultra(R) 94, the highest octane premium
gasoline commercially available in the United States, and 93, 89 and 87
octanes. Branded fuels sales (including middle distillates) by Sunoco
Northeast Marketing averaged 192.8 thousand barrels daily in 2000 compared to
185.6 thousand barrels daily in 1999 and 174.0 thousand barrels daily in 1998.
Ultra(R) 94 sales (including Ultra(R) 94 used as an octane enhancer in
Sunoco's mid-grade gasolines) accounted for approximately 18 percent of
Sunoco's retail gasoline sales in the Northeast in 2000.

                                       6


   Sunoco Northeast Marketing's operations include one of the largest home
heating oil businesses in the eastern United States. In 2000, the Company sold
home heating oil to approximately 136,000 households. Sunoco is also the
largest manufacturer and marketer of high performance (racing) gasoline in the
United States with approximately 9.2 million gallons sold during 2000.

   Sunoco's APlus(R) convenience stores are located principally in
Pennsylvania, New York and Massachusetts. These stores supplement sales of
fuel products with a broad mix of high-margin merchandise such as groceries,
fast foods and beverages. The following table sets forth information
concerning Sunoco's convenience store locations in the Northeast:



                                                               2000  1999  1998

   Number of Stores (at December 31)..........................   447   426   411
   Merchandise Sales (Thousands of Dollars/Store/Month)....... $61.8 $59.5 $52.5
   Merchandise Margin (Company Operated) (% of Sales)......... 26.8% 27.3% 28.7%


   The Company intends to grow its convenience store business through
acquisitions, new site construction and redesign of traditional gasoline
outlets in an effort to reduce its dependence on gasoline margins. Pursuant to
this strategy, in February 2001, Sunoco acquired from The Coastal Corporation
99 company-owned or leased convenience stores and 146 dealer-owned traditional
outlets located in 12 eastern states with the largest concentration in
Pennsylvania, New Jersey, Virginia and Tennessee.

   In the fourth quarter of 2000, Sunoco entered into an agreement with Wal-
Mart Stores, Inc. which will enable Sunoco to build and operate retail
gasoline outlets on sites at selected existing and future Wal-Mart locations
in nine eastern states. Sunoco expects to commence building 20 to 40 of these
facilities during the initial year of the agreement and add up to 100 new
sites per year in future years at an estimated cost of $50-$80 million per
year depending on configuration and store size. In addition to gasoline, these
sites will offer customers a limited selection of convenience store
merchandise. In conjunction with Wal-Mart, Sunoco is developing a new brand
that is planned for use at these facilities. This agreement will enable Sunoco
to market significantly more of its own gasoline production directly to the
consumer and to take further advantage of its existing logistics
infrastructure in the region.

   In the fourth quarter of 1998, Sunoco announced a Company-wide reimaging
program of its retail service station network. As part of this program, the
Company's Sunoco(R) logo has been updated and its retail outlet image has been
redesigned to provide a more contemporary appearance to Sunoco's outlets. The
roll-out of this program commenced in late 1998. As of December 31, 2000,
reimaging has been completed at all but approximately 150 of the Company's
1,100 owned or leased sites at a total cost of approximately $53 million.
Almost one-half of the Company's dealer and distributor owned sites have the
updated image. This program is expected to be substantially concluded by the
end of 2001.

 Sunoco Chemicals

   The Sunoco Chemicals business comprises the manufacturing, distribution and
marketing of base commodity and intermediate petrochemicals. These chemicals
include olefins and their derivatives (ethylene, ethylene oxide, refinery-
grade propylene and polypropylene), aromatics and their derivatives (benzene,
cumene, cyclohexane, toluene, xylene, phenol, acetone, bisphenol-A and
anilene) and plasticizers (phthalic anhydride, 2-ethylhexanol and phthalate
plasticizers). Sunoco Chemicals also produces polymer-grade propylene and
polypropylene at its Epsilon Products Company, LLC joint venture and MTBE at
its Belvieu Environmental Fuels joint venture.

   Petrochemicals are manufactured by Sunoco Chemicals at Sunoco's Marcus Hook
and Philadelphia refineries, at a phenol facility in Philadelphia,
Pennsylvania, at the joint venture MTBE facility in Mont Belvieu, Texas and at
the joint venture polypropylene facility in Marcus Hook (see below). (See
"Sunoco MidAmerica Marketing & Refining" for a discussion of the
petrochemicals produced at the Toledo refinery.)

   Effective January 1, 2001, Sunoco completed the acquisition of Aristech
Chemical Corporation ("Aristech"), a wholly owned subsidiary of Mitsubishi
Corporation ("Mitsubishi"), for $695 million, including approximately $115
million for working capital. Contingent payments with a net present value of
up to $167 million (the "earn out") may also be made if realized margins for
polypropylene and phenol exceed certain agreed upon thresholds over the next
six years. In connection with the transaction, Sunoco also entered into a
margin hedge agreement with Mitsubishi whereby Mitsubishi has provided
polypropylene margin protection in 2001 of up to $6.5 million per quarter. Any
earn out or margin hedge payments/receipts would be treated as adjustments to
the purchase price. In addition, Mitsubishi is responsible during a 25-year
indemnification period for up to $100 million of potential environmental
liabilities for the business arising out of or related to the period prior to
closing. Included in the purchase are Aristech's five chemical plants located
at Neal, WV; Haverhill, OH; Neville Island, PA; and Pasadena and LaPorte, TX
and a research center in Pittsburgh, PA. These facilities have the capacity to
produce annually 1.5 billion pounds of polypropylene, over 1.6 billion pounds
of phenol and related derivatives (including bisphenol-A), and 800 million
pounds of plasticizers. This acquisition integrates well with Sunoco
Chemicals' existing chemical operations and offers significant opportunities
for near-term synergies.

   Effective June 15, 2000, Sunoco Chemicals entered into the Epsilon Products
Company, LLC joint venture which combined Sunoco Chemicals' 735 million
pounds-per-year polymer-grade propylene operations at the Marcus Hook refinery
with the adjacent polypropylene business owned by Epsilon Products Company.
The polypropylene facility has the capacity to produce annually 750 million
pounds of homopolymer and copolymer polypropylene.

   On June 30, 1998, Sunoco acquired the Philadelphia phenol facility of
AlliedSignal Inc., now Honeywell International Inc. ("Honeywell") for $157
million. This facility has the capacity to produce annually more than one
billion pounds of phenol and 690 million pounds of acetone. In connection with
the acquisition, Sunoco Chemicals entered into a long-term contract to supply
Honeywell with approximately 740 million pounds of phenol annually at a price
based on the market value of cumene feedstock plus an amount approximating
other phenol production costs.

 **Reflects an increase of 6.5 thousand barrels daily in production capacity
  in the third quarter of 1998 as a result of an expansion project at the
  Philadelphia refinery (see below).
***Total production divided by 365 days. During the 184-day period after the
  June 30, 1998 acquisition of the phenol plant, phenol and acetone production
  totalled 7.6 and 6.7 thousand barrels daily, respectively.
  +Effective with the formation of the Epsilon Products Company, LLC joint
  venture on June 15, 2000, Sunoco Chemicals sells refinery-grade propylene to
  Epsilon Products Company, LLC. Prior to the formation of the joint venture,
  Sunoco Chemicals produced polymer-grade propylene for sale to Epsilon
  Products Company.
 ++Consists of benzene and refinery-grade propylene which are used in the
  manufacture of cumene and cyclohexane, and of cumene (after June 30, 1998)
  which is used in the manufacture of phenol and acetone.

   Effective November 1, 2000, Sunoco shut down its ethylene oxide plant
located in Brandenburg, KY. In connection with the shutdown, Sunoco recorded
an $11 million after-tax provision to write down the facility and recognize
related shutdown costs.

   Sunoco's petrochemical products are distributed and sold on a worldwide
basis with most of the sales made to customers in the United States. Sales of
petrochemicals to third parties by Sunoco Chemicals totalled 33.6 thousand
barrels daily in 2000 versus 33.3 thousand barrels daily in 1999 and 27.7
thousand barrels daily in 1998. The increased levels of both sales and
production volumes in the 1998-2000 period were due to the acquisition of the
phenol facility.

                                       9


   Sales made by Sunoco Chemicals during 2000 were distributed through the
following channels:

  . Benzene and Benzene Derivatives (including Cyclohexane)--Customers are
    large manufacturers of fibers, detergents and specialty products who buy
    a significant percentage of their requirements from Sunoco Chemicals
    under long-term contracts;

  . Toluene and Xylenes--Large-volume buyers participate in markets for
    fibers, film and urethane products. These sales are largely domestic with
    occasional export volumes. Customers and distributors also take
    individually small volumes of toluene and xylenes for paints, coatings,
    solvents and a variety of specialty applications;

  . Phenol and Acetone--Long-term phenol contract sales to Honeywell are used
    in nylon production. Other phenol contract sales are to large
    manufacturers of resins and adhesives primarily for use in building
    products. Large contract sales of acetone are to major customers who
    manufacture polymers. Other sales of acetone are made to individually
    smaller customers for use in inks, paints, varnishes and adhesives;

  . Propylene--Polymer-grade propylene sales were primarily made pursuant to
    a long-term contract to Epsilon Products Company prior to the formation
    of the Epsilon Products Company, LLC joint venture on June 15, 2000, with
    refinery-grade propylene sold to the joint venture after that date; and

  . Ethylene and Ethylene Oxide--Sales are primarily to intermediate-size
    specialty chemical companies that make diverse products such as
    surfactants, co-polymer resins and emulsions, and additives.

   The Epsilon Products Company, LLC joint venture sells polypropylene to a
diverse group of customers for use in fibers, carpeting, packaging,
automotive, furniture and other end products.

   The Belvieu Environmental Fuels joint venture sells MTBE to Sun Northeast
Refining for use in manufacturing reformulated gasoline.

   Benzene, extracted at Sunoco's Marcus Hook and Philadelphia refineries and
purchased from third parties, and refinery-grade propylene are used to produce
cumene at Philadelphia. The cumene is then used to produce phenol and acetone
at the phenol facility in Philadelphia. In the third quarter of 1998, Sunoco
Chemicals completed a project which expanded its cumene production capacity at
the Philadelphia refinery from 500 to 1,220 million pounds per year (4.5 to

technology.

 Sun Lubricants

   The Sun Lubricants business is comprised of the manufacturing of fuels and
lubricant products at the Tulsa refinery which are sold into process oil,
wholesale base oil and wax markets ("Western Lubricants") as well as the
manufacture and wholesale marketing of base oils and related fuels produced at
the Puerto Rico refinery and the blending, packaging and branded marketing of
specialty oils ("Value Added and Eastern Lubricants").

   During 2000, Sunoco announced its intention to sell its Value Added and
Eastern Lubricants operations. In connection with this decision, on January 9,
2001, Sunoco signed letters of intent to sell its lubricants blending and
packaging facilities in Tulsa, OK, and Richmond, CA, and its lubricants
branded marketing assets (which include the Kendall(R) motor oil brand and the
customer lists for both the Sunoco(R) and the Kendall(R) lubricants brands).
Negotiations concerning the sale of the Puerto Rico refinery and Marcus Hook
lubricants blending and packaging plant are ongoing and other options are also
under consideration for these assets.

   Base oils are sold to domestic and international customers who manufacture
their own finished transportation and industrial lubricants. Sun Lubricants
has also upgraded a significant portion of its

                                      10


base oil production into specialty oils at its blending and packaging
facilities. Upon completion of the divestment plan, some base oil production
at the Tulsa refinery will continue to be upgraded into process oils.

   The specialty oil operations held for sale include the production of
transportation and industrial lubricants as well as the manufacture of other
specialty lube products such as horticultural and agricultural oils, aromatic
and paraffinic rubber oils, paper defoamer oils, asphalt quality improvement
extracts, textile oils and finished waxes. These finished products have been
marketed under the Sunoco(R) and the Kendall(R) brand labels directly by
Sunoco or through distributors to a wide variety of domestic and foreign
customers.

 Sunoco MidAmerica Marketing & Refining

   The Sunoco MidAmerica Marketing & Refining ("Sunoco MidAmerica") business
consists of the retail sale of gasoline and middle distillates and the
operation of convenience stores in the Midwest as well as the manufacturing,
distribution and wholesale marketing of fuels and petrochemicals produced at
the Toledo refinery.

 Retail Marketing

   Sunoco MidAmerica markets, through direct and distributor channels, five
grades of retail gasoline products under the Sunoco(R) brand ranging from
Ultra(R) 94 to an 86 octane grade of gasoline. These outlets are located in
Indiana, Kentucky, Michigan, Ohio and West Virginia with the strongest market
presence in Michigan and Ohio. Sunoco MidAmerica is also the sole supplier to
all 16 gasoline outlets on the Ohio turnpike.

   The following table sets forth Sunoco's retail gasoline outlets in the
Midwest at December 31, 2000, 1999 and 1998:

   Branded fuels sales averaged 64.2 thousand barrels daily in 2000 compared to
59.9 thousand barrels daily in 1999 and 57.4 thousand barrels daily in 1998.
Ultra(R) 94 sales (including the Ultra(R) 94 used as an octane enhancer in
Sunoco's mid-grade gasolines) accounted for approximately 15 percent of
Sunoco's retail gasoline sales in the Midwest in 2000. The increases in branded
fuels sales during 2000 and 1999 are largely a result of new supply agreements
in the distributor channel. Sunoco MidAmerica expects these sales to increase
further in 2001 due to ongoing efforts to grow the brand.

   The following table sets forth information concerning Sunoco's convenience
stores in the Midwest:

   In late 1998, Sunoco MidAmerica began reimaging its service stations in
connection with Sunoco's company-wide reimaging program. As part of this
program, the Company's Sunoco Food Market(R) convenience stores are being
reimaged to APlus(R). As of December 31, 2000, reimaging has been completed at
521 locations, or 55 percent of the Company's total retail marketing outlets in
the Midwest. The program is expected to be substantially completed by the end
of 2001 at a total cost of approximately $17 million. (See "Sunoco Northeast
Marketing" above for a further discussion of this program.)

   Production volumes were essentially flat in 2000 despite a 40-day major
planned turnaround of one of the Toledo refinery's two crude units, the
catalytic cracking unit and other associated processing units as Sunoco
MidAmerica was able to achieve numerous monthly production records during the
year. Production volumes increased during 1999 despite both planned and
unplanned refinery maintenance activities and voluntary production cutbacks due
to the low margin environment. Production volumes during 1998 were impacted by
a one-month scheduled turnaround of one of the refinery's crude units and a
one-week shutdown of the refinery caused by a regional electricity emergency.

   Fuels products sold at wholesale to third parties from Sunoco's Toledo
refinery in 2000 averaged 71.8 thousand barrels daily compared to 78.2 thousand
barrels daily in 1999 and 75.1 thousand barrels daily in 1998.

   Ethanol blending is employed by Sunoco MidAmerica at its terminals in order
to reduce octane costs, simplify the product slate and enhance the storage and
transportation of gasoline products.

 Chemicals

   Sunoco MidAmerica chemical operations consist of the manufacturing of base
commodity and intermediate petrochemicals. These chemicals are comprised of
aromatics (including benzene, toluene and xylene), spirits, nonene and
tetramer. All of these products are sold under a marketing agreement with
Suncor Energy Inc. through a joint venture partnership that is managed by
Sunoco Chemicals. Almost all of the nonene and tetramer production is sold
under a long-term contract and a significant portion of the aromatics and
spirits production is sold into the solvents channel and/or higher-end
derivative markets. Sales of petrochemicals to third parties by Sunoco
MidAmerica totalled 8.7 thousand barrels daily in 2000 versus 9.1 thousand
barrels daily in 1999 and 10.1 thousand barrels daily in 1998.

 Sunoco Logistics

   The Sunoco Logistics business consists of crude oil and refined product
pipeline operations; domestic lease crude oil acquisition and related trucking
operations; crude oil terminalling; and product terminalling and transport
operations. These operations are conducted primarily in the Northeast, Midwest
and South Central regions of the United States.

   Pipeline operations are conducted through wholly owned subsidiaries and
through other pipelines in which Sunoco has an ownership interest. The
pipelines are principally common carriers and, as such, are regulated by the
Federal Energy Regulatory Commission for interstate movements and by state
regulatory agencies for intrastate movements. The tariff rates charged, while
regulated by the governing agencies, are based upon competition from other
pipelines or alternate modes of transportation.

   Sunoco Logistics crude oil pipeline operations, located primarily in the
South Central United States, transport crude oil produced in Oklahoma, Texas,
New Mexico and Louisiana to refiners (including Sunoco's Tulsa and Toledo
refineries) or to local trade points. The refined product pipeline operations,
located primarily in the Northeast and Midwest, transport gasoline, jet fuel,
diesel fuel, home heating oil and other products for Sunoco's other businesses
and for third-party integrated petroleum companies, independent marketers and
distributors.

   At December 31, 2000, Sunoco Logistics had an equity interest in 5,778
miles of crude oil pipelines and 4,641 miles of refined product pipelines. In
2000, crude oil and refined product shipments, including Sunoco's
proportionate share of shipments in pipelines in which it had an ownership
interest, totalled

                                      14


54.0 and 30.2 billion barrel miles, respectively, as compared to 49.4 and 32.0
billion barrel miles in 1999 and 53.8 and 30.6 billion barrel miles in 1998.

   Sunoco Logistics crude oil pipeline operations in the South Central United
States are complemented by lease crude oil acquisition and related trucking
operations. Approximately 176 thousand barrels daily of crude oil were
purchased from third-party leases during 2000. This crude oil is delivered to
various pipelines either directly from the wellhead or utilizing Sunoco
Logistics fleet of 145 trucks. Product terminalling and transport operations
include 35 terminals in the Northeast and Midwest that support Sunoco's
branded and wholesale marketing operations, 115 trucks that transport gasoline
and distillates and a railroad fleet of 80 owned and 2,400 leased tank cars
that primarily supports the Sunoco Chemicals and Sun Lubricants businesses.
The Company's marine transportation requirements are satisfied through the use
of third-party charters. Sunoco maintains an extensive vessel inspection
review and evaluation program to assure the vessels chartered into Sunoco
service are of appropriate quality.

   Sunoco's Nederland, TX, terminal provides approximately 10.5 million
barrels of storage and provides terminalling throughput capacity exceeding one
million barrels per day. Its Gulf Coast location provides local and midwestern
refiners access to foreign and offshore domestic crude oil. The facility is
also a key link in the distribution system for United States government
purchases for and sales from the Strategic Petroleum Reserve storage
facilities.

   In 2000, Sunoco Logistics entered into an agreement to participate in a
fiber optic network venture with a group of 12 natural gas, oil and liquid
petroleum pipeline companies and communications companies. The group will
provide Aerie Networks, Inc. the use of rights of way to construct a 20,000-
mile national broadband telecommunications network in exchange for equity in
the business. Sunoco Logistics will provide Aerie Networks, Inc. with use of
approximately 1,000 miles of pipeline rights of way. The venture, which is
expected to complete construction of the network by 2003, provides Sunoco
Logistics with an excellent opportunity to create value by making additional
use of existing assets.

   In 1999, Sunoco expanded its crude oil acquisition and pipeline businesses
in the South Central United States with the $36 million acquisition of Pride
Companies, L.P.'s 800-mile crude pipeline system, 800,000 barrels of tankage,
inventory and related assets, and 35 thousand barrels per day of third party
lease purchases.

   In 1998, Sunoco entered into an agreement to charter two new innovative
VLCCs (Very Large Crude Carriers) to transport crude oil to its Philadelphia
and Marcus Hook refineries. Construction of the two two-million-barrel-
capacity tankers is expected to be completed in 2001. The tankers will be put
on three-year charter to Sunoco at that time. The new VLCCs will provide
transportation cost savings compared to existing VLCCs and the smaller, one-
million-barrel-capacity tankers typically used to supply the Company's
Northeast refineries.

 Sun Coke

   Sun Coke Company's business consists of blast furnace coke manufacturing at
the Company's facilities in East Chicago, IN, and Vansant, VA, and
metallurgical coal production from mines in Virginia. Such operations are
conducted by Sun Coke Company and its affiliates.

   Sun Coke produces high-quality coke at its 1.3 million ton-per-year Indiana
Harbor cokemaking operation in East Chicago, IN, and at its 700 thousand ton-
per-year Jewell cokemaking operation in Vansant, VA. These facilities use Sun
Coke's proprietary low-cost, heat-recovery cokemaking technology, which is
environmentally superior to the chemical by-product recovery technology
currently used by other coke producers.

                                      15


   In 2000 and 1998, Sun Coke transferred interests in its Jewell and Indiana
Harbor cokemaking operations to third party investors in exchange for $214 and
$200 million, respectively, in cash. The investors in each operation are
currently entitled to 98 and 95 percent, respectively, of the cash flows and
tax benefits from the respective cokemaking operations until certain
cumulative return targets have been met. After these preferential return
periods, which are expected to end in 2007 for Jewell and 2002 for Indiana
Harbor, the investor in the Jewell operation will be entitled to a minority
interest in the cash flows and tax benefits from Jewell amounting to 18
percent, while the investor in the Indiana Harbor operation will be entitled
to a variable minority interest in the cash flows and tax benefits from
Indiana Harbor ranging from 5 to 23 percent.

   The following table sets forth information concerning Sun Coke's cokemaking
and coal mining operations:

*In February 1999, Sun Coke divested its Shamrock steam coal mining operation
located in Kentucky. With this divestment, Sun Coke ceased steam coal mining
activities.

   In 2000, 90 percent of Sun Coke's metallurgical coal production was
converted into coke at the Jewell cokemaking facility and 10 percent was sold
in spot market transactions. This is consistent with the Company's strategy of
using its metallurgical coal production predominantly in its Jewell cokemaking
operation. All of the metallurgical coal used to produce coke at Indiana
Harbor is purchased under short-term market rate contracts from third parties.

   Start-up of the Indiana Harbor cokemaking operation commenced in the first
quarter of 1998 and all four batteries at this facility, totalling 268 ovens,
have been producing at full rated capacity beginning in the second half of
1998. Production from this facility is sold to Ispat Inland Inc. ("Ispat") for
use at Ispat's Indiana Harbor Works steel plant located adjacent to Sun Coke's
facility. A supply agreement requires Sun Coke to provide Ispat 1.2 million
tons of coke annually on a take-or-pay basis through 2013. Additional
production of up to 150,000 tons per year will be sold either to Ispat or to
other steel producers. Ispat has agreed to purchase this production in 2001.
Sun Coke is also required to supply all of the flue gas by-product produced at
the cokemaking facility to a third-party utility for the generation of steam
and electricity. In return, the utility reduces the sulfur and particulate
content of the flue gas to acceptable emission levels.

   During 2000, 96 percent of Indiana Harbor's coke sales were made to Ispat
while 99 percent of Jewell's coke sales were made under a long-term contract
which provides for delivery of nearly all of this facility's coke production
to National Steel Corporation through April 1, 2005. Sun Coke's long-term
sales contracts contain cost pass through or escalating fixed price
provisions.


                                      16


   Sunoco intends to continue to grow its cokemaking business both in the
United States and internationally so that it can capitalize on its proprietary
cokemaking technology and realize additional earnings diversification and
growth. Pursuant to this strategy, during 2000, Sun Coke negotiated the
termination of an agreement entered into in 1995 with Raytheon Engineers and
Constructors, Inc. ("Raytheon"), which had provided Raytheon with exclusive
rights to market Sun Coke's cokemaking technology outside North America.

Competition

   The refining and marketing business is very competitive. Sunoco competes
with other domestic refiners and marketers in the northeastern United States
and U.S. Gulf Coast, with foreign refiners who import products into the United
States and with producers and marketers in other industries supplying other
forms of energy and fuels to consumers.

   Profitability in the refining and marketing industry depends largely on
refined product margins, as well as operating efficiency, product mix, and
costs of product distribution and transportation. Certain of Sunoco's
competitors that have larger and more complex refineries may be able to
realize lower per barrel costs or higher margins per barrel of throughput.
Several of Sunoco's principal competitors are integrated national or
international oil companies that are larger and have substantially greater
resources than Sunoco. Because of their integrated operations and larger
capitalization, these companies may be more flexible in responding to volatile
industry or market conditions, such as shortages of feedstocks or intense
price fluctuations. Refining margins are frequently impacted by sharp changes
in crude oil costs, which are not immediately reflected in product prices. A
large, rapid increase in crude oil prices adversely affects the Company's
operating margins if the increased costs cannot be recovered in the
marketplace.

   The refining industry is highly competitive with respect to feedstock
supply. Unlike certain of its competitors that have access to proprietary
sources of controlled crude oil production, Sunoco must obtain all of its
feedstocks from unaffiliated sources. Most of the crude oils processed in
Sunoco's refining system are light sweet crude oils. However, management
believes that any potential competitive impact of Sunoco's inability to
process significant quantities of less expensive heavy sour crude oils will
likely be mitigated by: the higher-value product slate obtained from light
sweet crude oils; the higher cost to process heavy sour crude oils; and the
continued availability of ample quantities of light sweet crude oils.

   Sunoco also faces strong competition in the market for the sale of retail
gasoline and merchandise. Sunoco's competitors include service stations of
large integrated gasoline companies, independent gasoline service stations,
convenience stores, fast food stores, and other similar retail outlets, some
of which are well-recognized national or regional retail systems. This
competition is expected to continue. The principal competitive factors
affecting Sunoco's retail marketing operations include: site location, product
price, selection and quality, appearance and cleanliness, hours of operation,
store safety, customer loyalty and brand recognition.

   Sunoco competes by pricing gasoline competitively, combining its retail
gasoline business with convenience stores which provide a wide variety of
branded products, and using effective advertising and promotional campaigns.
Sunoco believes that it is in a position to compete effectively as a marketer
of refined products because of the location of its Northeast and Midwest
refineries and retail network which are well integrated with its proprietary
distribution system.

   Sunoco's chemical business is largely a commodities business and competes
with local, regional, national and international companies, some of which have
greater financial, research and development, production and other resources
than Sunoco. Although competitive factors may vary among product lines, in
general, Sunoco's competitive position is primarily based on selling prices,
product quality, manufacturing technology, access to new markets, proximity to
the market and customer service and

                                      17


support. Sunoco's competitors can be expected in the future to improve
technologies, expand capacity, and, in certain product lines, develop and
introduce new products. While there can be no assurances of its ability to do
so, Sunoco believes that it will have sufficient resources to maintain its
current position. Sunoco faces similarly strong competition in the sale of
base oil lubricant products.

   Cokemaking operations are also highly competitive. Sun Coke's current
production is largely committed under long-term contracts; therefore,
competition mainly impacts its ability to obtain new contracts supporting
development of additional production capacity. Industry-wide domestic
consumption has declined steadily over the past several years as blast-furnace
steelmaking technology has improved and smaller, older blast furnaces have
shut down. U.S. coke production has declined even faster to about 85 percent
of consumption. Foreign coke has supplanted some of the declining U.S. coke
production as producers with aging coke plants have elected not to make the
additional capital investments required to maintain these facilities and
comply with the Clean Air Act. Sunoco believes the trend of shutting down
existing coke plants will continue and offers Sun Coke an opportunity to build
new plants. Sunoco also believes it is well-positioned to compete with other
coke producers since its proprietary technology allows Sunoco to construct
coke ovens that, when compared to conventional coke ovens, are more
environmentally benign, produce higher quality coke, are substantially less
costly to build, and require significantly fewer workers.

Research and Development

   In recent years, Sunoco's research and development activities have focused
on applied research, process and product development, and engineering and
technical services related to fuels, lubricants and chemicals. Sunoco spent $4
million on research and development activities in each of the years 2000, 1999
and 1998. As of December 31, 2000, approximately 90 scientists, engineers,
technicians and support personnel participated in these activities. Sunoco
owns or has made application for numerous patents in the U.S.

Employees

   As of December 31, 2000, Sunoco had approximately 12,300 employees compared
to approximately 11,300 employees as of December 31, 1999. The increase in
2000 is primarily attributable to an increase in company-operated convenience
stores. Approximately 45 percent of Sunoco's employees are employed in
company-operated convenience stores and service stations. Approximately 25
percent of Sunoco's employees were covered by 48 collective bargaining
agreements as of December 31, 2000. The collective bargaining agreements have
various terms and dates of expiration. In management's opinion, Sunoco's
relationship with its employees is generally satisfactory. In early 2001,
Sunoco added approximately 2,000 employees in connection with the acquisition
of Aristech Chemical Corporation and the purchase of retail gasoline sites
from The Coastal Corporation.

Environmental Matters

   Sunoco is subject to numerous federal, state and local laws which regulate
the discharge of materials into the environment or that otherwise relate to
the protection of the environment. These laws have required, and are expected
to continue to require, Sunoco to make significant expenditures of both a
capital and expense nature. The following table summarizes Sunoco's
expenditures for environmental projects and compliance activities (in millions
of dollars):

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

*Capital expenditures for pollution abatement are expected to approximate $45
and $100 million in 2001 and 2002, respectively.

                                      18


   In December 1999, the U.S. Environmental Protection Agency ("EPA") adopted
a rule which phases in limitations on the sulfur content of gasoline beginning
in 2004 and, in January 2001, adopted another rule which will require
limitations on the allowable sulfur content of diesel fuel beginning in 2006.
The diesel rule is being legally challenged by an industry group. The rules
include banking and trading credit systems, which could provide refiners
flexibility until 2006 for the low-sulfur gasoline and until 2010 for the low-
sulfur diesel. These rules are expected to have a significant impact on Sunoco
and its operations primarily with respect to the capital and operating
expenditures at the Philadelphia, Marcus Hook and Toledo refineries. Most of
the capital spending is likely to occur in the 2002-2005 period, while the
higher operating costs will be incurred when production of the low-sulfur
fuels commences. The Company estimates that the total capital outlays to
comply with the new gasoline requirements will be in the range of $200-$250
million. The Company cannot estimate the capital requirements of the new
diesel standards at this time. The ultimate impact of the rules may be
affected by such factors as technology selection, the effectiveness of the
banking and trading credit systems, timing uncertainties created by permitting
requirements and construction schedules and any effect on prices created by
changes in the level of gasoline and diesel fuel production.

   The EPA has issued a series of information requests to several U.S.
refiners pursuant to Section 114 of the Clean Air Act as part of an
enforcement initiative relating to New Source Review ("NSR"), leak detection
and repair ("LDAR"), Benzene Waste NESHAP, and start-up/shut-down
malfunctions. Sunoco received Section 114 information requests in 2000
pertaining to its five refineries and its phenol facility in Philadelphia, PA.
Sunoco has completed its response to the requests and has provided additional
clarification requested by the EPA, which is focusing solely on the refineries
at this time. While Sunoco has not been named in any proceeding, it is
currently evaluating its position and is engaging in discussions with the EPA
concerning these issues.

   The EPA has proposed a legislative framework for Congress that would
significantly reduce or eliminate the use of MTBE, the primary oxygenate used
by Sunoco and the industry to meet the reformulated gasoline requirements
under the Clean Air Act. The EPA has also proposed removing the oxygenate
requirement and replacing it with an alternative, although the specifics for
the alternative have not yet been developed. They have also initiated a
rulemaking process to consider restrictions or a ban on the use of MTBE. A
number of states have either already banned the use of MTBE in gasoline or are
currently studying the issue. California, Connecticut and New York are among
those states that have enacted legislation to ban its use beginning in 2003 or
2004; however, the legislation in California and New York has been legally
challenged. If MTBE is banned throughout the United States, the effect on
Sunoco will depend on the specific regulations, the cost and availability of
alternative oxygenates if the minimum oxygenate requirements remain in effect,
and the ability of Sunoco to recover its costs in the marketplace. A wholly
owned subsidiary of the Company is a one-third partner in Belvieu
Environmental Fuels ("BEF"), a joint venture that owns and operates an MTBE
production facility in Mont Belvieu, TX. At December 31, 2000, the Company had
a $57 million investment in this operation. The joint venture is currently
evaluating alternative uses for this facility in the event MTBE is banned.

   Any required cleanup of groundwater aquifers contaminated by MTBE would be
driven by cleanup thresholds based on drinking water protection. Though not
all groundwater is used for drinking, several states have initiated or
proposed lowering MTBE cleanup thresholds. While actual cleanup costs for
specific sites are variable and depend on many factors, lowered thresholds for
MTBE remediation would cause costs at some sites to increase.

   Private litigants, purportedly on behalf of classes of private well owners
in numerous states, filed class action lawsuits against major petroleum
refiners and marketers who sold gasoline containing MTBE, alleging MTBE may
have contaminated groundwater. One such class action was filed in New York on
behalf of New York well owners. (Berisha, et al v. Amerada Hess Corporation,
et al, Case No. 00-CIV-1898-SAS, United States District Court, Southern
District of New York.) Sunoco is one of

                                      19


sixteen petroleum refiner and marketer defendants in this lawsuit. Sunoco has
filed a motion to dismiss the complaint. Early discovery has been allowed by
the judge and is proceeding. The Judicial Panel on Multidistrict Litigation
has consolidated this matter for pretrial purposes with another similar case
in which Sunoco is not a defendant seeking the same remedies on behalf of
class members in sixteen other states in the United States District Court for
the Southern District of New York. Sunoco is not a defendant in any other MTBE
class action case.

   The Comprehensive Environmental Response Compensation and Liability Act
("CERCLA") and the Solid Waste Disposal Act as amended by the Resource
Conservation and Recovery Act ("RCRA"), and related federal and state laws
subject Sunoco to the potential obligation to remove or mitigate the
environmental effects of the disposal or release of certain pollutants at
Sunoco's facilities and at third-party or formerly owned sites. Under CERCLA,
Sunoco is subject to potential joint and several liability for the costs of
remediation at sites at which it has been identified as a "potentially
responsible party" ("PRP"). As of December 31, 2000, Sunoco had been named as
a PRP at 50 sites identified or potentially identifiable as "Superfund" sites
under CERCLA.

   Under various environmental laws, including RCRA, Sunoco has initiated
corrective remedial action at its facilities, formerly owned facilities and
third-party sites and could be required to undertake similar actions at
various other sites.

   Sunoco establishes accruals related to environmental remediation activities
for work at identified sites where an assessment has indicated that cleanup
costs are probable and reasonably estimable. For a discussion of the accrued
liabilities and charges against income related to these activities, see Note
14 to the consolidated financial statements in the Company's 2000 Annual
Report to Shareholders.

   Total future costs for environmental remediation activities will depend
upon, among other things, the identification of any additional sites, the
determination of the extent of the contamination at each site, the timing and
nature of required remedial actions, the technology available and needed to
meet the various existing legal requirements, the nature and extent of future
environmental laws, inflation rates and the determination of Sunoco's
liability at multi-party sites, if any, in light of the number, participation
level and financial viability of other parties.

   Management believes that the environmental matters discussed above are
potentially significant with respect to results of operations or cash flows
for any one year. However, management does not believe that such matters will
have a material impact on Sunoco's consolidated financial position or, over an
extended period of time, on Sunoco's cash flows or liquidity.

ITEM 3. LEGAL PROCEEDINGS

   Many legal and administrative proceedings are pending against Sunoco.
Although the ultimate outcome of these proceedings cannot be ascertained at
this time, it is reasonably possible that some of them could be resolved
unfavorably to Sunoco. Management of Sunoco believes that any liabilities
which may arise from such proceedings would not be material in relation to the
consolidated financial position of Sunoco at December 31, 2000.

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

   None.
