  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 1999 Annual Report to Shareholders for a discussion of the
factors which 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 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 petrochemicals, and the
transportation of crude oil and refined products. These 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 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 1999 Annual Report to Shareholders.
Business segment information is also presented in Note 19 to the Consolidated
Financial Statements in the Company's 1999 Annual Report to Shareholders.

Refining and Marketing

  The Company's refining and marketing operations consist of the manufacturing
and marketing of fuels, lubricants and petrochemicals and the transportation
of crude oil and refined products. These operations are conducted principally
through Sunoco, Inc. (R&M), a wholly owned subsidiary of the Company. The
Company's refining and marketing operations are classified into the following
six business units: Sun Northeast Refining; Sunoco Northeast Marketing; Sunoco
Chemicals; Sun Lubricants; Sunoco MidAmerica Marketing & Refining; and Sunoco
Logistics.

  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

*Excludes approximately 30-35 thousand barrels per day of reduced crude oil
processed at the Puerto Rico refinery. Subsequent to its reconfiguration in
the first quarter of 1997, this facility processes reduced crude oil instead
of conventional crude oil (see "Sun Lubricants" below).

  Supply and Distribution

  Sunoco meets all of its crude oil requirements through purchases from third
parties. There is 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 1999. 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 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
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. With
the completion of this work in July 1998, all three of Sunoco's catalytic
cracking units in the Northeast had been modernized during the 1997-98 period.
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 will enable the
upgrade of products previously used as refinery fuel into higher value
products.

  The Philadelphia and Marcus Hook refineries process predominantly light
sweet crude oils, which are supplied from foreign sources. The following table
sets forth information concerning the crude oil purchased for processing at
these refineries (in thousands of barrels daily):

   Total fuels products sold to third parties at wholesale by Sun Northeast
Refining in 1999 were 365.6 thousand barrels daily compared to 353.8 thousand
barrels daily in 1998 and 358.4 thousand barrels daily in 1997. Sales to other
Sunoco business units by Sun Northeast Refining (primarily gasoline, middle
distillates and chemical feedstocks) totalled 197.5, 186.1 and 182.9 thousand
barrels daily in 1999, 1998 and 1997, 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 agreed to
substantive terms with FPL Energy ("FPL") which will permit FPL to build, own
and operate a 725-megawatt, natural gas fired cogeneration power plant at
Sunoco's Marcus Hook refinery. Steam supplied by the power plant will reduce
the refinery's steam supply costs. Construction of the plant is expected to
begin in late 2000.

 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
New England and Mid-Atlantic states. These activities are conducted in a 12-
state region from Maine through northern Virginia, 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 109.6, 103.8
 and 99.8 thousands of gallons monthly during 1999, 1998 and 1997,
 respectively. The improvement during the 1997-99 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, 1999 were 54
outlets on limited access highways in Pennsylvania, New Jersey, New York and
Maryland. Of these outlets, 37 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.

                                       6
<PAGE>

  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:

</TABLE>

  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.

  Sunoco Northeast Marketing 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 185.6 thousand barrels daily in 1999 compared to 174.0
thousand barrels daily in 1998 and 169.6 thousand barrels daily in 1997.
Ultra(R) 94 sales (including Ultra(R) 94 used as an octane enhancer in
Sunoco's mid-grade gasolines) accounted for approximately 23 percent of
Sunoco's retail gasoline sales in the Northeast in 1999.

  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, 1999,
reimaging has been completed at 644 locations, primarily those owned or leased
by the Company. This represents approximately 25 percent of the Company's
total retail marketing outlets in the Northeast. The program is expected to be
substantially completed by the end of 2000 for Company owned or leased sites
at a total cost of approximately $65 million. Reimaging of dealer and
distributor owned sites is expected to be concluded by the end of 2001.

 Sunoco Chemicals

  The Sunoco Chemicals business includes the manufacturing, distribution and
marketing of base commodity and intermediate petrochemicals. These chemicals
are comprised principally of olefins and their derivatives (ethylene, ethylene
oxide and propylene) and aromatics and their derivatives (benzene, cumene,
cyclohexane, toluene, xylene, phenol and acetone). As a partner in a joint
venture, Sunoco Chemicals also produces MTBE which is utilized by Sun
Northeast Refining in manufacturing reformulated gasoline. Petrochemicals are
manufactured by Sunoco Chemicals at Sunoco's Marcus Hook and Philadelphia
refineries, at a phenol facility in Philadelphia, Pennsylvania, at an
ethylene/ethylene oxide facility in Brandenburg, Kentucky and at the joint
venture MTBE facility in Mont Belvieu, Texas. (See "Sunoco MidAmerica
Marketing & Refining" for a discussion of the petrochemicals produced at the
Toledo refinery.)

  On June 30, 1998, Sunoco acquired the Philadelphia phenol facility of
AlliedSignal Inc. ("Allied") for $157 million. This acquisition was made
pursuant to the Company's strategy to expand its chemicals business by
manufacturing intermediate products further down the value chain. This
facility has the capacity to produce annually more than one billion pounds of
phenol and 620 million pounds of acetone. In connection with the acquisition,
Sunoco Chemicals entered into a long-term contract to supply Allied 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. Sunoco intends to continue to grow its chemicals business.

  *Calendar-day basis.
 **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.
  +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.

  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 33.3 thousand
barrels daily in 1999 versus 27.7 thousand barrels daily in 1998 and 24.4
thousand barrels daily in 1997. The increased levels of both sales and
production volumes in the 1997-99 period were due to the acquisition of the
phenol facility.

  Sales volumes during 1999 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;

                                       8
<PAGE>

  . Toluene and Xylenes--Buyers generally purchase large volumes for fibers,
    film and urethane products. These sales are made in both the contract and
    spot markets and tend to be international in scope. 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 AlliedSignal 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;

  . Polymer-grade Propylene--Sales are primarily made pursuant to a long-term
    contract to Epsilon Products Co. ("Epsilon"), a polypropylene
    manufacturer (see below); 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.

  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 to expand its cumene production capacity at the
Philadelphia refinery from 500 to 1,220 million pounds per year (4.5 to 11.0
thousand barrels per day). The expanded facility, which utilizes a new
catalyst technology, produced cumene at an annualized rate of 1,012 million
pounds during the fifteen-month period ended December 31, 1999. Opportunities
exist for incremental expansions of polymer-grade propylene, cumene, phenol
and acetone.

 Sun Lubricants

  The Sun Lubricants business is comprised of the manufacturing, blending,
packaging and marketing of a broad line of paraffinic and aromatic lubricating
and specialty oils produced at the Tulsa and Puerto Rico refineries as well as
the manufacturing and wholesale marketing of the fuels produced at these
facilities.

  Base oils are sold to domestic and international customers who manufacture
their own finished transportation and industrial lubricants. Sun Lubricants
also upgrades a significant portion of its base oil production into specialty
oils at its blending and packaging facilities. Blending and packaging
operations are conducted principally at lube service centers located at the
Marcus Hook and Tulsa refineries for Sunoco and third parties.

  Specialty oil production is comprised principally of transportation and
industrial lubricants. Sun Lubricants also produces 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 are marketed under
the Sunoco(R) and Kendall(R) brand labels directly by Sunoco or through
distributors to a wide variety of domestic and foreign customers.

*Excludes approximately 30-35 thousand barrels per day of reduced crude oil
processed at the Puerto Rico refinery (see discussion below).

  Production volumes during 1998 were limited by a 59-day maintenance
turnaround at the Puerto Rico refinery as well as by a two-week shutdown of
this facility due to Hurricane Georges. After completion of the maintenance
turnaround in April 1998, lubricants production increased at the refinery. The
16.5 thousand barrels per day of base oils produced by Sun Lubricants during
1999 represents a record level of lubricants production.

  In 1997, Sun Lubricants reconfigured the Puerto Rico refinery to eliminate
the processing of conventional crude oil and to process, instead,
approximately 30-35 thousand barrels per day of reduced crude oil. This change
significantly reduced the amount of unprofitable fuels produced at the
facility while fully maintaining the volume and quality of lubricants
production. The streamlining of the Puerto Rico refining operation has
improved operating efficiency, lowered fixed costs and reduced ongoing capital
spending and working capital requirements.

  Sales of specialty oil lubricant products totalled 11.0 thousand barrels
daily in 1999 versus 11.0 thousand barrels daily in 1998 and 11.7 thousand
barrels daily in 1997 while sales of base oils totalled 7.8 thousand barrels
daily in 1999 versus 6.9 thousand barrels daily in 1998 and 7.1 thousand
barrels daily in 1997. Fuels and waxes sold to third parties from the Tulsa
and Puerto Rico refineries totalled 83.3 thousand barrels per day in 1999
compared to 82.9 thousand barrels per day in 1998 and 99.5 thousand barrels
per day in 1997. The significant decline in fuels and wax sales in 1998
reflects a decline in fuels sales resulting from the Company's strategy to
significantly reduce fuels production at the Puerto Rico refinery.

  Branded fuels sales averaged 59.9 thousand barrels daily in 1999 compared to
57.4 thousand barrels daily in 1998 and 54.1 thousand barrels daily in 1997.
Ultra(R) 94 sales (including the Ultra(R) 94 used as an octane enhancer in
Sunoco's mid-grade gasolines) accounted for approximately 19 percent of
Sunoco's retail gasoline sales in the Midwest in 1999. The increases in
branded fuels sales during 1999 and 1998 are largely a result of new supply
agreements in the distributor channel. Sunoco MidAmerica expects these sales
to increase further in 2000 due to ongoing efforts to grow the brand.

  In late 1998, Sunoco MidAmerica began reimaging its service stations in
connection with Sunoco's company-wide reimaging program. As of December 31,
1999, reimaging has been completed at 268 locations, or 30 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 $16 million. (See "Sunoco Northeast Marketing" above for a

  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 Toledo 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 1999 averaged 78.2 thousand barrels daily compared to 75.1
thousand barrels daily in 1998 and 74.0 thousand barrels daily in 1997.

  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 9.1 thousand barrels daily in 1999 versus 10.1 thousand
barrels daily in 1998 and 10.8 thousand barrels daily in 1997.

 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 refinery) 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, 1999, Sunoco Logistics had an equity interest in 5,966 miles
of crude oil pipelines and 4,641 miles of refined product pipelines. In 1999,
crude oil and refined product shipments, including Sunoco's proportionate
share of shipments in pipelines in which it had an ownership interest,
totalled

                                      13
<PAGE>

49.4 and 32.0 billion barrel miles, respectively, as compared to 53.8 and 30.6
billion barrel miles in 1998 and 58.9 and 29.7 billion barrel miles in 1997.

  Sunoco Logistics crude oil pipeline operations in the South Central United
States are complemented by lease crude oil acquisition and related trucking
operations. Approximately 147 thousand barrels daily of crude oil were
purchased from third-party leases during 1999. This crude oil is delivered to
various pipelines either directly from the wellhead or utilizing Sunoco
Logistics fleet of 150 trucks. Product terminalling and transport operations
include 37 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 155 owned and 2,560 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 ten 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 increasing volumes of 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 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
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 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.

  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. Sun Coke is also required to supply all of the flue gas
by-product produced at

                                      14
<PAGE>

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.

  Sunoco intends to continue to grow its cokemaking business so that it can
capitalize on its proprietary cokemaking technology and realize additional
earnings diversification and growth.

  In 1997, Sun Coke completed a 9-year program to replace the existing coke
ovens at its Jewell cokemaking facility with 142 new ovens. This program has
resulted in an improvement in overall cost efficiencies and an enhancement in
coke quality.

  In 1998, Sun Coke transferred an interest in its Indiana Harbor cokemaking
operation to a third party for $200 million in cash. In 1995, Sun Coke
transferred an interest in its Jewell cokemaking operation to another third
party for $95 million in cash. The investors in each operation are entitled to
95 percent 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 2002 and 2000,
respectively, the third parties will be entitled to variable minority
interests in the cash flows and tax benefits from the respective operations
ranging from 5 to 25 percent.

*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 1999, 86 percent of Sun Coke's metallurgical coal production was
converted into coke at the Jewell cokemaking facility and 14 percent was sold
in spot market transactions. This is consistent with the Company's strategy,
adopted in the fourth quarter of 1998, 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.

  During 1999, all of Indiana Harbor's coke sales were made to Ispat (see
above) while 98 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.

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. The recent consolidation and
convergence experienced in the refining and marketing industry has reduced the
number of competitors. However, it has not reduced competition. Sunoco
believes the current trend of industry restructuring may continue. As a
result, the business environment may become more competitive, while providing
the Company with opportunities to expand its operations.

  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 multi-national 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 passed on to customers.

  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: location of stores,
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 chemicals businesses compete with national, regional and local
companies throughout North America, largely on the basis of costs and service.
Sunoco's petrochemicals business is largely a commodities business, with
pricing and quality being the most important factors. Sunoco faces similarly
strong competition in the sale of petroleum lubricants in largely fragmented
markets.

  Cokemaking operations are also highly competitive. While domestic coke
consumption has stabilized over the past two years, U.S. coke production has
declined to about 80 percent of consumption. Lower quality foreign coke has
supplanted some U.S. coke production as aging coke

                                      16
<PAGE>

plants have been adversely impacted by the Clean Air Act. Sunoco believes the
shutdown of 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 Sunoco's proprietary technology allows
Sunoco to construct coke ovens that, compared to conventional coke ovens, are
more environmentally benign, are generally less costly to build, and can be
operated with 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, $4 and $5 million on research and development activities in 1999, 1998 and
1997, respectively. As of December 31, 1999, 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, 1999, Sunoco had approximately 11,300 employees compared
to approximately 11,100 employees as of December 31, 1998. The increase in
1999 is primarily attributable to an increase in company-operated convenience
stores, partially offset by the divestment of the Company's Shamrock steam
coal mining operations. Approximately 40 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 45 collective
bargaining agreements as of December 31, 1999. The collective bargaining
agreements have various terms and dates of expiration. In management's
opinion, Sunoco's relationship with its employees is generally satisfactory.

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 $25
and $35 million in 2000 and 2001, respectively.

  The Clean Air Act of 1990, as amended (the "Clean Air Act") establishes
stringent criteria for regulating air toxics at operating facilities by
mandating major reductions in allowable emissions and establishing a more
comprehensive list of substances deemed to be air toxics. The Clean Air Act
also requires refiners to market cleaner-burning gasoline that reduces
emissions of certain toxics and conventional pollutants. The Company has
implemented the first two phases of the reformulated gasoline regulations
which require an increase in the minimum quantity of oxygen for certain non-
attainment areas, a reduction in benzene content, and a reduction in
summertime Reid Vapor Pressure ("RVP"). Sunoco expects to implement the more
stringent final phase of these regulations in the spring of 2000.

                                      17
<PAGE>

  Pursuant to the Clean Air Act, in December 1999 the U.S. Environmental
Protection Agency ("EPA") issued a final rule to require more stringent
emissions standards ("Tier 2 Standards") for new passenger cars and light duty
trucks. The final rule mandates significant reductions in the sulfur levels in
reformulated and conventional gasoline commencing in 2004. The rule includes a
banking and trading credit system, which could provide refiners compliance
flexibility until 2006. Sunoco currently has gasoline sulfur levels which are
below the industry average and idle assets which may be used to help meet this
new requirement. Analysis of the rule to determine its impact and to identify
compliance alternatives by the required dates is ongoing. The rule could 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. The capital spending is likely to begin in early 2003 while
the higher operating costs will be incurred when production of the low-sulfur
gasoline commences. The ultimate impact of the rule cannot be determined at
this time, and may be affected by such factors as technology selection, the
effectiveness of the banking and trading credit system, timing uncertainties
created by permitting requirements and construction schedules and any effect
on prices created by changes in the level of gasoline production.

  In November 1998, the EPA convened an advisory Panel on Oxygenate Use in
Gasoline (the "Panel"). The purpose of the Panel was to review public health
and environmental issues that have been raised by the use of MTBE in gasoline,
and specifically by the discovery of MTBE in water supplies. The Panel made
its recommendations to the EPA on July 27, 1999. The recommendations call for
the improved protection of drinking water from MTBE contamination, a
substantial reduction in the use of MTBE, and action by Congress to remove the
oxygenate requirements for reformulated gasoline under the Clean Air Act.
State and federal environmental agencies could implement the majority of the
recommendations, and some would require Congressional legislative action.
While the Panel recommended that certain public and private funding options be
explored for the clean up of contaminated sites, it made no specific
recommendations concerning such funding options. However, private parties are
seeking clean-up remedies primarily from East and West Coast gasoline
marketers, including Sunoco. California has acted to ban MTBE use by December
31, 2002. In connection with the MTBE ban, California has requested a waiver
from the EPA of its oxygenate requirements. Other states are also reviewing
the use of MTBE in gasoline. MTBE is the primary oxygenate used by Sunoco and
throughout the industry to meet the reformulated gasoline requirements under
the Clean Air Act. While phase-outs or restrictions on the use of MTBE or any
required clean up of MTBE could have a significant impact on Sunoco and its
results of operations, the ultimate impact cannot be determined at this time.

  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, 1999, Sunoco had been named as
a PRP at 52 sites identified or potentially identifiable as "Superfund" sites
under CERCLA. Sunoco has reviewed the nature and extent of its involvement at
each site and other relevant circumstances and, based upon the other parties
involved or Sunoco's negligible participation therein, believes that its
potential liability associated with such sites will not be significant.

  Under various environmental laws, including RCRA, Sunoco has initiated
corrective remedial action at Sunoco's facilities, formerly-owned facilities
and third-party sites and could be required to undertake similar actions at
various other sites. The cost of such remedial actions could be significant
but is expected to be incurred over an extended period of time.

                                      18
<PAGE>

  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 1999 Annual
Report to Shareholders.

  On October 4, 1996, Sunoco filed a complaint in Los Angeles County Superior
Court, Jalisco Corporation, Inc., et al. v. Argonaut Insurance Company, et al.
(Case No. BC 158441), naming more than 45 insurance companies as defendants
and seeking recovery under numerous insurance policies for certain
environmental matters of Sunoco, including its predecessor companies and
subsidiaries, arising from the ownership and operation of its businesses. In
1999 and 1998, the Company entered into several settlements which resolved
most of these claims. As a result, the Company received net cash proceeds
totalling $4 million in 1998, $96 million in 1999 and $28 million in early
2000. Pretax gains of $73 million ($47 million after tax) and $58 million ($38
million after tax) were recognized in 1999 and 1998, respectively, in
connection with these settlements.

  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 of 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 overall expenditures for environmental
activities are likely to be significant but are expected to be incurred over
an extended period of time and to be funded from Sunoco's net cash provided by
operating activities. Although potentially significant with respect to results
of operations or cash flows for any one year, management believes that such
costs will not have a material impact on Sunoco's consolidated financial
position or, over an extended period of time, on Sunoco's cash flows or
liquidity.

Year 2000 Information Processing

  During the 1997-99 period, Sunoco assessed, remediated or replaced, tested
and implemented computer systems and applications in order that they would be
able to operate and properly process information dated after December 31,
1999. As a result of these efforts, the Company has not experienced any Year
2000 failures of its key computer systems and applications. Likewise, the
Company's key customers and suppliers have been able to continue to meet their
obligations to the Company. Although unlikely, the possibility still exists
that interruptions to Company and/or key customer and supplier operations or
business activities could occur as a result of lingering Year 2000 Issues.
Such interruptions, if they were to occur, could have a material adverse
impact on Sunoco's consolidated results of operations or financial condition.

ITEM 3. LEGAL PROCEEDINGS

  In 1999, Sunoco, Inc. (R&M) and Atlantic Refining and Marketing Corp., an
affiliate of Sunoco, paid civil fines aggregating $106,000 under a 1996
Consent Decree executed with the United States Environmental Protection Agency
Region III (acting through the United States Department of Justice), and
lodged in the United States District Court for the Eastern District of
Pennsylvania. These payments stem from several alleged NPDES permit violations
at Sunoco's Philadelphia refinery.

  Many other 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, 1999.

                                    Bylaws


Article I: Directors

Membership

     Section 1.  The business and affairs of the Corporation shall be managed by
a Board of Directors consisting of the number of Directors equal to those
elected at the annual meeting of shareholders or as may from time to time be
determined by the Board, except that it shall not consist of less than five
members.  Except as hereinafter provided in the case of vacancies, Directors
shall be elected by ballot at the annual meeting of shareholders and shall hold
office for one year and until successors are duly elected and qualified, or
until earlier resignation or removal.  Directors need not be residents of the
state of the Commonwealth of Pennsylvania.

Vacancies

     Section 2.  Vacancies in the Board of Directors may be filled by a majority
of the incumbent members of the Board, though such majority be less than a
quorum.  If the number of Directors is at any time increased, the incumbent
Directors may by majority vote elect any additional Director.  Such newly
elected Director shall hold office until the next annual meeting of the
shareholders and until a successor is elected and qualified, or until earlier
resignation or removal.

Emergency Board

     Section 3.  In the event of any emergency by reason of nuclear attack or
other attacks by enemy forces upon the North American Continent, there shall be
constituted without further action or authority an Emergency Board of Directors.
In the event of an emergency by reason of physical disasters of national or
greater scope, an attack upon the United States outside the North American
Continent, or an imminent threat of an attack or physical disaster of national
or greater scope upon the North American Continent, there shall be constituted
an Emergency Board of Directors by declaration of the Chairman of the Board of
Directors.  The Emergency Board shall consist of at least three members from the
regular Board of Directors or from officers of the Corporation or its
subsidiaries who are not members of the regular Board of Directors but who have
been designated as alternate members of the Emergency Board. The Emergency Board
may exercise all of the powers of the regular Board of Directors in the
management of the business, affairs and property of the Corporation during the
emergency and until such time as the regular Board of Directors shall resume the
exercise of its powers.

     The original members of the Emergency Board shall be the Chairman, the
President and the Executive Vice Presidents who are members of the Board of
Directors, provided however, that any vacancy existing because of the
unavailability of any two of the foregoing persons shall be filled by the
alternate members.  The Chairman of the Board shall serve as Chairman of any
meeting of the Emergency Board or, in the event of his unavailability for any
reason, the President or an Executive Vice President, in order designated by the
Chairman of the Board, shall serve in this capacity.  In the event of the
unavailability for any reason of all of the foregoing persons, an alternate
member shall serve as Chairman at any meeting of the Emergency Board in the
order previously designated for membership by resolution of the regular Board of
Directors.

                                       1
<PAGE>

     Meetings may be called by any member of the Emergency Board.  Two members
shall constitute a quorum for the transaction of business and the act of any two
members present at a meeting shall be the act of the Emergency Board.  Meetings
may be held by any means of communication and Directors shall be deemed present
if they are in communication with other directors by any means.  Notice of
meetings may be given at any time and in any manner, provided that a reasonable
effort shall be made to give actual notice to each member of the Emergency
Board.

     To the extent not inconsistent with this Section 3 of Article I, the Bylaws
in their entirety shall remain in effect during any such emergency.  No officer,
Director or employee acting in good faith in accordance with this Section 3 of
Article I or any resolutions made pursuant hereto, shall be liable for his
conduct unless it is willful misconduct.

Liability of Directors

     Section 4.  A Director of the Corporation shall not be personally liable
for monetary damages, as such, for any action taken or any failure to take any
action, unless (1) he has breached the duties of his office or has failed to
perform his duties as a Director in good faith, in a manner he reasonably
believed to be in the best interest of the Corporation and with such care,
including reasonable inquiry, skill and diligence, as a person of ordinary
prudence would use under similar circumstances; and (2) the breach or failure to
perform constitutes self-dealing, willful misconduct or recklessness.

Nomination of Directors

     Section 5.  Nominations for election to the Board of Directors may be made
by shareholders entitled to vote for the election of Directors only in the
manner specified in this Section.  Shareholders may submit nominations for
consideration by a committee appointed by the Board of Directors for that
purpose.  A nomination proposed to be made at an annual meeting shall be
submitted in writing to the Secretary of the Corporation no later than the
December 31 prior to the annual meeting at which such nomination is intended to
be considered.  Nominations may be made at any meeting of shareholders called
for the purpose of election of Directors other than an annual meeting only upon
written notice of the shareholder's intent to make such nominations at the
meeting delivered to the Secretary of the Corporation at least sixty (60) days
prior to the date of such meeting; provided, however, that if the date of such
meeting is first publicly announced or disclosed (in a public filing or
otherwise) less than seventy (70) days prior to the date of such meeting, such
prior notice shall be given not more than ten (10) days after such date is first
so announced or disclosed.  Such nominations and written notice of any
nominations by shareholders under this section shall contain the following
information:

     (a)  name, residence and business address of the nominating shareholder;

     (b)  a representation that the shareholder is a record holder or beneficial
owner of the Corporation's voting shares and a statement of the number of such
shares;

     (c)  a representation that the shareholder intends to appear in person or
by proxy at the meeting to nominate the individuals specified in the notice, if
the nominations are to be made at a meeting of shareholders;

                                       2
<PAGE>

     (d)  information regarding each nominee such as would be required to be
included in a proxy statement;

     (e)  a description of all arrangements or understandings between and among
the shareholder and each and every nominee; and

     (f)  the written consent of each nominee to serve as a Director, if
elected.

The judge of election or the person presiding at the meeting, in the absence of
the judge of election, shall determine whether any nomination is made according
to these procedures and should be accepted.  Such decision shall be deemed
conclusive and binding on all shareholders of the Corporation.

Director in writing either before or after the meeting.

Waiver of Notice

from among its members.  To the extent permitted by Pennsylvania law, the
Executive Committee may exercise all or any of the powers of the Board of
Directors in the management of the business, affairs and property of the

that no action shall be taken by the Executive Committee if any member of such

Directors for the ensuing year and for the transaction of such other business as
may be properly brought before the meeting shall be held each year on such day
and at such time and place, either within or without Pennsylvania, as shall be
determined in advance by the Board of Directors.

Special Meetings

     Section 2.   Special meetings of the shareholders may be called at any time
by the Chairman of the Board of Directors or by the order of the Board of
Directors.  Special meetings of the shareholders may also be called by any
shareholder entitled to call such a meeting pursuant to, and in compliance with,
the provisions of Article TENTH of the Articles of Incorporation of the
Corporation.  A shareholder wishing to call a special meeting of the
shareholders of the Corporation shall give written notice to the Secretary of
the Corporation which shall (a) certify that such shareholder is the record
owner of at least ten percent (10%) of the outstanding shares of the
Corporation's Voting Stock, (b) contain such shareholder's undertaking to
continue to hold, at all times from the date of such notice until the final
adjournment of such special meeting, at least ten percent of the outstanding
shares of the Corporation's Voting Stock, (c) specify the proposal or proposals
such shareholder desires to have submitted for shareholder action at such
special meeting, and (d) include all other material and information required to
be submitted or provided pursuant to law, the Corporation's Articles of
Incorporation and these Bylaws, including, without limitation, Article I,
Section 5 hereof, if applicable, given the nature of such shareholder's proposal
or proposals.

     The Secretary of the Corporation promptly shall transmit such notice to the
Board of Directors which shall, within sixty days following the date on which
such notice is received by the Secretary, determine the sufficiency of the
notice and whether any one or more of the shareholder's proposals constitutes a
"Proper Matter for Shareholder Consideration" as set forth herein.  A
shareholder's proposal shall be deemed a "Proper Matter for Shareholder
Consideration" unless, pursuant to Rule 14a-8(c) promulgated under the
Securities Exchange Act of 1934, as amended (or any similar or successor rule or
regulation), the Corporation would be entitled to omit such proposal from its
proxy statement for an annual meeting of shareholders had such proposal been
timely submitted to the Corporation for consideration at

                                       7
<PAGE>

such annual meeting of shareholders in accordance with Rule 14a-8. No special
meeting of shareholders shall be held at the call of a shareholder unless there
has been a determination by the Board of Directors that (i) the notice submitted
by the shareholder complies with the requirements of this Section, and (ii) at
least one of the proposals of such shareholder is a Proper Matter for
Shareholder Consideration; provided, however, that only proposals submitted by
the calling shareholder which are determined to be Proper Matters for
Shareholder Consideration shall be considered at such special meeting of
shareholders. Notwithstanding the foregoing, nothing herein shall prohibit the
Board of Directors from submitting matters to the shareholders at any special
meeting of shareholders including, without limitation, a special meeting of
shareholders called by a shareholder.

     A shareholder calling a special meeting of shareholders shall reimburse the
Corporation for all costs incurred by it in connection with such special meeting
of shareholders including, without limitation, the costs of preparing and
disseminating a proxy statement or information statement in connection with, and
soliciting proxies to be voted at, such special meeting of shareholders.  A
special meeting of shareholders of the Corporation called by a shareholder in
accordance with Article Tenth of the Articles of Incorporation shall be held at
such date, time and place as is determined by the Board of Directors of the
Corporation, which date shall be not later than ninety days after the date on
which the Board of Directors shall have determined that the shareholder has duly
called such meeting by giving proper written notice to the Secretary of the
Corporation and has otherwise complied with applicable law and the Articles of
Incorporation and Bylaws of the Corporation.

Notice

     Section 3.    Unless waived, written notice of the time, place and purpose
of every meeting of the shareholders shall be given by the Secretary not less
than five nor more than ninety days before the date of the meeting either
personally or by sending a copy of such notice by mail, e-mail or other
electronic transmission, to each shareholder of record entitled to vote at such
meeting.

Quorum

     Section 4.a.  Unless otherwise provided in the Articles of Incorporation,
by statute or these Bylaws, at all meetings of shareholders, the presence in
person or by proxy, of shareholders entitled to cast a majority of the votes
which all shareholders are entitled to cast at the meeting shall constitute a
quorum for the transaction of business.

Quorum at Shareholder-called Special Meeting

     Section 4.b.  At any special meeting of shareholders called by a
shareholder pursuant to Article Tenth of the Corporation's Articles of
Incorporation, the presence, in person or by proxy, of shareholders entitled to
cast at least sixty-six and two thirds percent (66 2/3%) of the votes which all
shareholders are entitled to cast shall constitute a quorum for the transaction
of business.

No Waiver of Quorum

     Section 4.c.  Section 1756(b) of the BCL (and any successor provision of
similar import) shall not be applicable with respect to any special meeting of
shareholders called by a shareholder pursuant to Article Tenth of the
Corporation's Articles of Incorporation, or to any adjournment thereof.  If a
special meeting of shareholders called by a shareholder pursuant to Article
Tenth of the Corporation's Articles of Incorporation cannot be organized for
lack of a

                                       8
<PAGE>

quorum under Section 4.b of these Bylaws, such special meeting shall be deemed
finally adjourned without the taking of any shareholder action.

Voting

     Section 5.  When a quorum is present at any meeting of the shareholders,
the shareholders entitled to vote and casting a majority of the votes at the
meeting shall decide any question brought before such meeting, unless the
question is one which, by express provision of law, the Articles of
Incorporation, or these Bylaws, requires a different vote, in which case such
express provision shall govern and control the decision of such question.  The
shareholders present in person or by proxy at any duly organized meeting may
continue to do business until adjournment, notwithstanding the withdrawal of
enough shareholders to leave less than a quorum.

Adjournment

     Section 6.  The holders of shares entitled to cast a majority of the votes
present or represented at any meeting may adjourn the meeting from time to time,
though such majority constitutes less than a quorum.  When a meeting is
adjourned to another time or place, it shall not be necessary to give notice of
the adjourned meeting if the time and place to which the meeting is adjourned
are announced at the meeting adjourning and at the adjourned meeting only such
business is transacted as might have been transacted at the original meeting.

Proxies

     Section 7.  Every shareholder entitled to vote at a meeting of shareholders
or to express consent or dissent without a meeting may authorize another person
or persons to act for him by proxy.  Every proxy shall be executed or
authenticated by the shareholder or by his duly authorized attorney-in-fact, and
filed with, or transmitted to, the Secretary of the Corporation or its
designated agent.  A shareholder, or his duly authorized attorney-in-fact, may
execute or authenticate a writing or transmit an electronic message authorizing
another person to act for him by proxy.  A telegram, telex, cablegram, datagram,
e-mail, internet communication or other means of electronic transmission from a
shareholder or attorney-in-fact, or a photographic, facsimile or similar
reproduction of a writing executed by a shareholder or attorney-in-fact, will be
treated as properly executed or authenticated for purposes of this section if it
sets forth or utilizes a confidential and unique identification number or other
mark furnished by the Corporation to the shareholder for the purposes of a
particular meeting or transaction.  No proxy shall be valid after eleven months
from the date of its execution, authentication or transmission, unless a longer
time is expressly provided therein.  Unless it is coupled with an interest, a
proxy shall be revocable, notwithstanding any other agreement or any provision
in the proxy to the contrary.  Revocation of a proxy shall not be effective
until notice thereof has been given to the Secretary of the Corporation or its
designated agent in writing or by electronic transmission.  A proxy shall not be
revoked by the death or incapacity of the shareholder but shall continue in
force until revoked by the personal representative or guardian of the
shareholder.  The presence at any meeting of a shareholder who has given a proxy
shall not revoke such proxy unless the shareholder shall give notice of such
revocation in writing, or by electronic transmission, to the Secretary of the
meeting prior to the voting of such proxy.

each shareholder. The information contained in such list shall be made available

Record Date

     Section 9.   For the purpose of determining the shareholders entitled to

or to express consent to or dissent from any proposal without a meeting, or for
the purpose of determining shareholders entitled to receive payment of any

Board of Directors may fix, in advance, a record date for any such determination
of shareholders.  Such date shall not be more than ninety days before the date
of such meeting nor more than ninety days prior to any other action.  In such
case only such shareholders as shall be shareholders of record on the date so

payment of such dividend, or to receive such allotments of rights or to exercise
such rights, as the case may be, notwithstanding transfer of any shares on the
books of the Corporation after any record date so fixed.  When the determination
of shareholders of record entitled to notice of or to vote at any meeting of

shareholders.  The certification shall be in the form specified by the
Corporation and shall include such information as the name, address and number
of shares of the beneficial owners, taxpayer identification number, and any

specified, in place of the nominee shareholder of record.

of any shareholder entitled to vote thereat shall, make such appointment.  In
case any person appointed as judge of election fails to appear or act, the
vacancy may be filled by appointment made by the Board in advance of the meeting
or at the meeting by the person presiding thereat.  Each judge of election,
before entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of judge of election at such meeting with
strict impartiality and according to the best of his ability.  No person shall
be elected a Director at a meeting at which he has served as a judge of

Prior Notice of Shareholder Proposals

     Section 12.  At any annual or special meeting of shareholders, proposals by
shareholders (other than proposals of a shareholder calling a special meeting of
shareholders pursuant to Article Tenth of the Corporation's Articles of
Incorporation) shall be considered only if (a) such proposal is a "Proper Matter
for Shareholder Consideration" as set forth herein, and (b) prior notice thereof
has been timely given as provided herein.  A shareholder's proposal shall be
deemed a "Proper Matter for Shareholder Consideration" unless, pursuant to Rule
14a-8(c) promulgated under the Securities Exchange Act of 1934, as amended (or
any similar or successor rule or regulation), the Corporation would be entitled
to omit such proposal from its proxy statement for an annual meeting of
shareholders had such proposal been timely submitted to the Corporation for
consideration at such annual meeting of shareholders in accordance with Rule
14a-8.

     Notice of any proposal to be presented by any shareholder (outside the
solicitation of proxies pursuant to the rules and regulations of the Securities
and Exchange Commission) at an annual meeting of shareholders shall be delivered
in writing to the Secretary of the Corporation not later than December 31 prior
to the annual meeting of shareholders at which such proposal is to be presented.
Notice of any proposal to be presented by any shareholder at any special meeting
of shareholders shall be delivered in writing to the Secretary of the
Corporation not less than sixty (60) days prior to the date of such special
meeting; provided, however, that if the date of such special meeting is first
publicly announced or disclosed (in a public filing or otherwise) less than
seventy (70) days prior to the date of such special meeting, such prior notice
shall be given not more than ten (10) days after such date is first so announced
or disclosed. Notice of any such proposal to be presented at any shareholders
meeting shall include: the text of the proposal to be presented, a brief written
statement of the reasons for such shareholder's support of the proposal, the
name and address of record of the proposing shareholder, the number and class of
all shares of each class of stock of the Corporation beneficially owned by such
shareholder, a representation that the shareholder is the holder of Voting Stock
of the Corporation, is entitled to vote at such meeting and intends to appear in
person or by proxy to present the proposal at such meeting.  It shall also
describe, in detail, any material interest of such shareholder in the proposal.
If the Board of Directors, after affording the shareholder a reasonable
opportunity to cure any deficiency which the Board of Directors identifies in
the original notice, determines that notice of a proposal was not effected in
accordance with the foregoing procedure, then such proposal shall not be
eligible for consideration at the meeting and such determination shall be
conclusive and binding upon the Corporation and its shareholders.

Agents and Registrars of stock as it may deem advisable and may define their
powers and duties.

right of a person registered on its books as the owner of shares to receive

               participation in or significantly reduce such Participant's
               benefits under, any employee benefit plan or

                                       5

               compensation plan in which such Participant was participating
               immediately prior to the Change in Control, provided, however,
               that in the aggregate such actions by the Company significantly
               reduce the Participant's total compensation (i.e., the sum of
               Participant's annual base salary, guideline (target) bonus, and
               the aggregate value to the Participant of all employee benefit
               and compensation plans); or the failure by the Company, without
               the Participant's consent, to pay to the Participant any portion
               of the Participant's current compensation, or to pay to the
               Participant any portion of an installment of deferred
               compensation under any deferred compensation program of the
               Company; or

                    (4) The Company requires the Participant to be based
               anywhere other than the Participant's present work location or a
               location within thirty-five (35) miles from the present location;
               or the Company requires the Participant to travel on Company
               business to an extent substantially more burdensome than such
               Participant's travel obligations during the period of twelve (12)
               consecutive months immediately preceding the Change in Control;

          provided, however, that in the case of any such termination of
          employment by the Participant under this subparagraph (b), such
          termination shall not be deemed to be a Qualifying Termination unless
          the termination occurs within 120 days after the occurrence of the
          event or events constituting the reason for the termination; or

               (c)  a termination of employment by the Company other than a
          termination for Just Cause, or a termination of employment by the
          Participant for one of the reasons set forth in (b) above, following a
          Potential Change in Control, if the Participant can demonstrate that
          such termination or circumstance in (b) above leading to termination:

                    (1)  was at the request of a third party with which the
               Company had entered into negotiations or an agreement with regard
               to a Change in Control; or

                    (2)  otherwise occurred in connection with, or in
               anticipation of, a Change in Control;

          provided, however, that in either such case, such Change in Control
          actually occurs within one (1) year following the Employment
          Termination Date.

          1.32 Stock Options - shall have the meaning provided herein at
Section 3.1.

          1.33 Subsidiary - shall mean any corporation of which, at the time
more than fifty percent (50%) of the shares entitled to vote generally in an
election of directors are owned directly or indirectly by Sunoco, Inc. or any
subsidiary thereof.

                                  ARTICLE II

       Background, Purpose and Term of Plan; Participation & Eligibility for
Benefits

     2.1  Background. Effective on December 31, 1996, no further awards shall be
made under the Sunoco, Inc. Executive Long-Term Stock Investment Plan adopted in
May, 1991 provided, however, that any rights theretofore granted under that plan
shall not be affected.

     2.2  Purpose of the Plan. The purposes of this Sunoco, Inc. Long-Term
Performance Enhancement Plan (the "Plan") are to:

          (a) better align the interests of shareholders and management of the
     Company by creating a direct linkage between Participants' rewards and
     shareholders' gains;

          (b) provide management with the ability to increase equity ownership
     in Sunoco, Inc.;

          (c) provide competitive compensation opportunities which can be
     realized through attainment of performance goals; and

          (d) provide an incentive to management for continuous employment with
     the Company.

     It is intended that most awards made under the Plan will qualify as
performance-based compensation under Section 162(m) of the Code.

     2.3  Term of the Plan. This Plan shall become effective upon approval by
the holders of a majority of the votes present, in person or represented by
proxy, at the 1997 Annual Meeting of Shareholders of the Company. No awards will
be made under the Plan after December 31, 2001, unless the Board of Directors
extends this date to a date no later than December 31, 2006. The Plan and all
awards made under the Plan prior to such date (or extended date) shall remain in
effect until such awards have been satisfied or terminated in accordance with
the Plan and the terms of such awards.

     2.4  Administration. The Plan shall be administered by the Committee which
shall have the authority, in its sole discretion and from time to time to:

          (a) designate the employees or classes of employees eligible to
     participate in the Plan (each such employee being, a "Participant");

          (b) grant awards provided in the Plan in such form and amount as the
     Committee shall determine;

          (c) impose such limitations, restrictions and conditions upon any such
     award as the Committee shall deem appropriate; and

          (d) interpret the Plan, adopt, amend and rescind rules and regulations
     relating to the Plan, and make all other determinations and take all other
     action necessary or advisable for the implementation and administration of
     the Plan.

                                       7
<PAGE>

     The decisions and determinations of the Committee on all matters relating
to the Plan shall be in its sole discretion and shall be conclusive. No member
of the Committee shall be liable for any action taken or not taken or decision
made or not made in good faith relating to the Plan or any award thereunder.

     2.5  Eligibility for Participation. Participants in the Plan shall be the
officers and other key employees of the Company who occupy responsible
managerial or professional positions and who have the capability of making a
substantial contribution to the success of the Company. In making this selection
and in determining the amount of awards, the Committee shall consider any
factors deemed relevant, including the individual's functions, responsibilities,
value of services to the Company and past and potential contributions to its
profitability and sound growth.

     2.6  Types of Awards Under the Plan. Awards under the Plan may be in the
form of any one or more of the following:

          (a)  Stock Options, as described in Article III;

          (b)  Incentive Stock Options, as described in Article IV;

          (c)  Limited Rights, as described in Article V; and/or

          (d)  Common Stock Units, as described in Article VI.

     2.7  Aggregate Limitation on Awards. Shares of stock which may be issued
under the Plan shall be Common Stock. The maximum number of shares of Common
Stock which may be issued under the Plan shall be four million (4,000,000). For
purposes of calculating the maximum number of shares of Common Stock which may
be issued under the Plan:

          (a) all the shares issued (including the shares, if any, withheld for
     tax withholding requirements) shall be counted when cash is used as full
     payment for shares issued upon exercise of an Option;

          (b) only the shares issued (including the shares, if any, withheld for
     tax withholding requirements) net of shares of Common Stock used as full or
     partial payment for such shares upon exercise of an Option;

          (c) only the shares issued (including the shares, if any, withheld for
     tax withholding) upon vesting and payment of the Common Stock Units, shall
     be counted.

     In addition to shares of Common Stock actually issued pursuant to the
exercise of Options, there shall be deemed to have been issued a number of
shares equal to the number of shares of Common Stock in respect of which Limited
Rights (as described in Article V) shall have been exercised. Shares tendered by
a Participant as payment for shares issued upon exercise of an Option, shall be
available for issuance under the Plan. Any shares of Common Stock subject to an
Option, which for any reason is terminated unexercised or expires shall again be
available for issuance under the Plan, but shares subject to an Option which are
not issued as a result of the exercise of Limited Rights shall not be available
for issuance under the Plan.

          (d) The maximum number of Options that shall be granted with respect
     to each calendar year to a Participant shall be two-hundred thousand.

                                       8
<PAGE>

          (e) The maximum number of Common Stock Units granted with respect to
     each calendar year to a Participant shall be fifty thousand.

          (f) The maximum number of Common Stock Units granted under the Plan
     will be one million.

     The share limits set forth in this Section 2.7 shall be adjusted to reflect
any capitalization changes as discussed in Section 7.9.


                                  ARTICLE III

                                 Stock Options

     3.1  Award of Stock Options. The Committee, from time to time, and subject
to the provisions of the Plan and such other terms and conditions as the
Committee may prescribe, may grant to any Participant in the Plan one or more
options to purchase for cash or shares the number of shares of Common Stock
("Stock Options") allotted by the Committee. The date a Stock Option is granted
shall mean the date selected by the Committee as of which the Committee allots a
specific number of options to a Participant pursuant to the Plan.

     3.2  Stock Option Agreements. The grant of a Stock Option shall be
evidenced by a written Stock Option Agreement, executed by the Company and the
holder of a Stock Option, stating the number of shares of Common Stock subject
to the Stock Option evidenced thereby, and in such form as the Committee may
from time to time determine.

     3.3  Stock Option Price. The Option Price per share of Common Stock
deliverable upon the exercise of a Stock Option shall be not less than 100% of
the Fair Market Value of a share of Common Stock on the date the Stock Option is
granted.

     3.4  Term and Exercise. The term and the vesting schedule of the Stock
Options shall be determined by the Committee. However, no Stock Option may be
exercisable before the second anniversary of the date of grant or after the
tenth anniversary of such date. No Stock Option shall be exercisable after the
expiration of its term.

     3.5  Manner of Payment. Each Stock Option Agreement shall set forth the
procedure governing the exercise of the Stock Option granted thereunder, and
shall provide that, upon such exercise in respect of any shares of Common Stock
subject thereto, the Optionee shall pay to the Company, in full, the Option
Price for such shares with cash or with Common Stock. All shares of Common Stock
issued under the Sunoco, Inc. Long-Term Incentive Plan, the Sunoco, Inc.
Executive Long-Term Stock Investment Plan or this Plan must be held at least six
months before they may be used as payment of the Option Price.

     3.6  Issuance and Delivery of Shares. As soon as practicable after receipt
of payment, the Company shall deliver to the Optionee a certificate or
certificates for such shares of Common Stock. The Optionee shall become a
shareholder of the Company with respect to Common Stock represented by share
certificates so issued and as such shall be fully entitled to receive dividends,
to vote and to exercise all other rights of a shareholder.

                                       9
<PAGE>

     3.7  Retirement or Disability. Upon termination of the Optionee's
employment by reason of retirement or permanent disability (as each is
determined by the Committee), the Optionee may, within sixty (60) months from
the date of termination, exercise any Stock Options to the extent such options
are exercisable during such 60-month period.

     3.8  Termination for Other Reasons. Except as provided in Sections 3.7 and
3.9, or except as otherwise determined by the Committee, upon termination of an
Optionee's employment, all unvested Stock Options shall terminate immediately,
and all vested Stock Options shall terminate:

       (a) immediately, in the case of an Optionee terminated by the Company for
     Just Cause; or

       (b) upon the expiration of ninety (90) calendar days following the date
     of termination of an Optionee's employment, other than for Just Cause;

  provided, however, that the Limited Rights awarded in tandem with such Stock
  Options shall not terminate and such Limited Rights shall remain exercisable
  during the Exercise Period for any Optionee whose employment relationship with
  the Company has been terminated as a result of any Qualifying Termination.

     3.9  Death of Optionee. Any rights in respect of Stock Options to the
extent exercisable on the date of the Optionee's death may be exercised by the
Optionee's estate or by any person that acquires the legal right to exercise
such Stock Option by bequest, inheritance, or otherwise by reason of the death
of the Optionee. Any such exercise to be valid must occur within the remaining
option term of the Stock Option. The foregoing provisions of this Section 3.9
shall apply to an Optionee who dies while employed by the Company and to an
Optionee whose employment may have terminated prior to death; provided, however,
that:

          (a) an Optionee who dies while employed by the Company will be treated
     as if the Optionee had retired on the date of death. Accordingly, the
     Optionee's estate or a person who acquires the right to exercise such Stock
     Option by bequest or inheritance will have the right to exercise the Stock
     Option in accordance with Section 3.7; or

          (b) the estate or a person who acquires the right to exercise a stock
     option by bequest or inheritance from an Optionee who dies after
     terminating employment with the Company will have the remainder of any
     exercise period provided under Sections 3.7 and 3.8.

     3.10 Acceleration of Options.  Notwithstanding any provisions to the
contrary in agreements evidencing Options granted thereunder, each outstanding
Option shall become immediately and fully exercisable upon the occurrence of any
Change in Control of Sunoco, Inc.

     3.11 Effect of Exercise.  The exercise of any Stock Options shall cancel
that number of related Limited Rights, if any, which is equal to the number of
shares of Common Stock purchased pursuant to said options.

                                   ARTICLE IV

                            Incentive Stock Options

     4.1  Award of Incentive Stock Options.  The Committee, from time to time,
and subject to the provisions of the Plan and such other terms and conditions as
the Committee may prescribe, grant to any Participant in the Plan one or more
"incentive Stock Options" (intended to qualify as such under the provisions of
Section 422 of the Internal Revenue Code of 1986, (the "Code") as amended
("Incentive Stock Options")) to purchase for cash or shares the number of shares
of Common Stock allotted by the Committee. The date an Incentive Stock Option is
granted shall mean the date selected by the Committee as of which the Committee
allots a specific number of options to a Participant pursuant to the Plan.
Notwithstanding the foregoing, Incentive Stock Options shall not be granted to
any owner of ten percent (10%) or more of the total combined voting power of the
Company and its subsidiaries.

     4.2  Incentive Stock Option Agreements. The grant of an Incentive Stock
Option shall be evidenced by a written Incentive Stock Option Agreement,
executed by the Company and the holder of an Incentive Stock Option stating the
number of shares of Common Stock subject to the Incentive Stock Option evidenced
thereby, and in such form as the Committee may from time to time determine.

     4.3  Incentive Stock Option Price. The Option Price per share of Common
Stock deliverable upon the exercise of an Incentive Stock Option shall not be
less than 100% of the Fair Market Value of a share of Common Stock on the date
the Incentive Stock Option is granted.

     4.4  Term and Exercise. The term and the vesting schedule of the Incentive
Stock Option shall be determined by the Committee. However, no Incentive Stock
Option may be exercisable before the second anniversary of the date of grant or
after the tenth anniversary of such date. No Incentive Stock Option shall be
exercisable after the expiration of its term.

     4.5  Limits on Incentive Stock Options. Each Incentive Stock Option shall
provide that, if the aggregate Fair Market Value of the stock on the date of
grant with respect to which Incentive Stock Options are exercisable for the
first time by an Optionee during any calendar year, under this Plan or any other
stock option plan of the Company exceeds One Hundred Thousand Dollars
($100,00.00), then the option, as to the excess shall be treated as a non-
qualified stock option. An incentive Stock Option shall not be granted to any
person who is not an "employee" of the Company (within the meaning of Section
424(f) of the Code).

     4.6  Retirement or Disability. Upon the termination of the Optionee's
employment by reason of retirement or permanent disability (as each is
determined by the Committee), the Optionee may, within sixty (60) months from
the date of such termination of employment, exercise any Incentive Stock Options
to the extent such Incentive Stock Options are exercisable during such 60-month
period. Notwithstanding the foregoing, the tax treatment available pursuant to
Section 422 of the Internal Revenue Code of 1986 upon the exercise of an
Incentive Stock Option will not be available to an Optionee who exercises any
Incentive Stock Option more than:

          (a) twelve (12) months after the date of termination of employment due
     to permanent disability; or

          (b) three (3) months after the date of termination of employment due
     to retirement.

                                       11
<PAGE>

     4.7  Termination for Other Reasons. Except as provided in Sections 4.6
and 4.8, or except as otherwise determined by the Committee, upon termination of
an Optionee's employment, all unvested Incentive Stock Options shall terminate
immediately, and all vested Incentive Stock Options shall terminate:

          (a) immediately, in the case of an Optionee terminated by the Company
  for Just Cause; or

          (b) upon the expiration of ninety (90) calendar days following the
  date of termination of an Optionee's employment other than for Just Cause;

provided, however, that the Limited Rights awarded in tandem with such Incentive
Stock Options shall not terminate and such Limited Rights shall remain
exercisable during the Exercise Period for any Optionee whose employment
relationship with the Company has been terminated as a result of any Qualifying
Termination.

     4.8  Death of Optionee. Any rights in respect of Incentive Stock Options to
the extent exercisable on the date of the Optionee's death may be exercised by
the Optionee's estate or by any person that acquires the legal right to exercise
such Stock Option by bequest, inheritance, or otherwise by reason of the death
of the Optionee. Any such exercise to be valid must occur within the remaining
option term of the Incentive Stock Option. The foregoing provisions of this
Section 4.8 shall apply to an Optionee who dies while employed by the Company
and to an Optionee whose employment may have terminated prior to death;
provided, however, that:

          (a)  an Optionee who dies while employed by the Company will be
     treated as if the Optionee had retired on the date of death. Accordingly,
     the Optionee's estate or a person who acquires the right to exercise such
     Incentive Stock Option by bequest or inheritance will have the right to
     exercise the Incentive Stock Option in accordance with Section 4.6; or

          (b)  the estate or a person who acquires the right to exercise a stock
     option by bequest or inheritance from an Optionee who dies after
     terminating employment with the Company will have the remainder of any
     exercise period provided under Section 4.6 and 4.7.

     4.9  Applicability of Stock Options Selections. Section 3.5, Manner of
Payment, Section 3.6, Issuance and Delivery of Shares, Section 3.10,
Acceleration of Options and Section 3.11, Effect of Exercise, applicable to
Stock Options, shall apply equally to Incentive Stock Options. Said Sections are
incorporated by reference in this Article IV as though fully set forth herein.

                                   ARTICLE V

                                 Limited Rights

     5.1  Award of Limited Rights. Concurrently with or subsequent to the award
of any Option, the Committee may, subject to the provisions of the Plan and such
other terms and conditions as the Committee may prescribe, award to the Optionee
with respect to each Option, a related limited right permitting the Optionee,
during a specified limited time period, to be paid the appreciation on the
Option in lieu of exercising the Option ("Limited Right").

     5.2  Limited Rights Agreement. Limited Rights granted under the Plan shall
be evidenced by written agreements in such form as the Committee may from time
to time determine.

     5.3  Exercise Period. Limited Rights are immediately exercisable in full
upon grant for a period of up to seven (7) months following the date of a Change
in Control (the "Exercise Period").

     5.4  Amount of Payment. The amount of payment to which an Optionee shall be
entitled upon the exercise of each Limited Right shall be equal to 100% of the
amount, if any, which is equal to the difference between the Option Price of the
related Option and the Market Price of a share of such Common Stock. Market
Price is defined to be the greater of:

          (a) the highest price per share of Common Stock paid, in connection
     with any Change in Control, during the period from the date of occurrence
     of a Potential Change in Control through the ninetieth (90/th/) day
     following the subsequent related Change in Control; and

          (b) the highest price per share of Common Stock reflected in the
     consolidated trading tables of The Wall Street Journal (presently the New
     York Stock Exchange Composite Transactions quotations) during the 60-day
     period prior to the Change in Control.

     5.5  Form of Payment. Payment of the amount to which an Optionee is
entitled upon the exercise of Limited Rights, as determined pursuant to Section
5.4, shall be made solely in cash.

     5.6  Effect of Exercise. If Limited Rights are exercised, the Stock
Options, if any, related to such Limited Rights cease to be exercisable to the
extent of the number of shares with respect to which the Limited Rights were
exercised. Upon the exercise or termination of the Options, if any, related to
such Limited Rights, the Limited Rights granted with respect thereto terminate
to the extent of the number of shares as to which the related Options were
exercised or terminated; provided, however, that with respect to Options that
are terminated as a result of the termination of the Optionee's employment
status, the Limited Rights awarded in tandem therewith shall not terminate and
such Limited Rights shall remain exercisable during the Exercise Period for any
Optionee whose employment relationship with the Company has been terminated as a
result of any Qualifying Termination.

     5.7  Retirement or Disability. Upon termination of the Optionee's
employment by reason of permanent disability or retirement (as each is
determined by the Committee), the Optionee

                                       13
<PAGE>

may, within six (6) months from the date of termination, exercise any Limited
Rights to the extent such Limited Right is exercisable during such six-month
period.

     5.8  Death of Optionee or Termination for Other Reasons. Except as provided
in Sections 5.7 and 5.9 or except as otherwise determined by the Committee, all
Limited Rights granted under the Plan shall terminate upon the termination of
the Optionee's employment or upon the death of the Optionee.

     5.9  Termination Related to a Change in Control. The requirement that an
Optionee be terminated by reason of retirement or permanent disability or be
employed by the Company at the time of exercise pursuant to Sections 5.7 and 5.8
respectively, is waived during the Exercise Period as to any Optionee whose
employment relationship with the Company has been terminated as a result of any
Qualifying Termination.


                                   ARTICLE VI

                               Common Stock Units

     6.1  Award of Common Stock Units. The Committee, from time to time, and
subject to the provisions of the Plan, may grant to any Participant in the Plan
rights to receive shares of Common Stock which are subject to a risk of
forfeiture by the Participant ("Common Stock Units"). At the time it grants any
Common Stock Units, the Committee shall determine whether the payment of such
Common Stock Units shall be conditioned upon either:

          (a) the Participant's continued employment with the Company throughout
     a stated period (Section 6.4); or

          (b) the attainment of certain predetermined performance objectives
     during a stated period (Section 6.5).

     The date Common Stock Units are granted shall mean the date selected by the
Committee as of which the Committee allots a specific number of Common Stock
Units to a Participant pursuant to the Plan.

     6.2  Common Stock Unit Agreements. Common Stock Units granted under the
Plan shall be evidenced by written agreements stating the number of Common Stock
Units evidenced thereby or in such form and as the Committee may from time to
time determine.

     6.3  Dividend Equivalents. A holder of Common Stock Units will be entitled
to receive payment from the Company in an amount equal to each cash dividend
("Dividend Equivalent") the Company would have paid to such holder had he, on
the record date for payment of such dividend, been the holder of record of
shares of Common Stock equal to the number of Common Stock Units which had been
awarded to such holder as of the close of business on such record date. The
Company shall establish a bookkeeping account on behalf of each Participant in
which the Dividend Equivalents that would have been paid to the holder of Common
Stock Units ("Dividend Equivalent Account") shall be credited. The Dividend
Equivalent Account will not bear interest.

                                       14
<PAGE>

     6.4  Performance Period. Upon making an award, the Committee shall
determine (and the Common Stock Unit Agreement shall state) the length of the
applicable period during which employment must be maintained or certain
performance targets must be attained (the "Performance Period"). Performance
Periods will normally be from three (3) to five (5) years; however, the
Committee at its sole discretion may establish other time periods.

     6.5  Performance Goals. Common Stock Units and the related Dividend
Equivalent Account earned may be based upon the attainment of Performance Goals
established by the Committee in accordance with Section 162(m). Within the first
ninety (90) days of the Performance Period, the Committee shall establish, in
writing, the weighted Performance Goals and related Performance Factors for
various goal achievement levels for the Company. In establishing the weighted
Performance Goals, the Committee shall take the necessary steps to insure that
the Company's ability to achieve the preestablished goals is uncertain at the
time the goals are set. The established written Performance Goals, assigned
weights, and Performance Factors shall be written in terms of an objective
formula, whereby any third party having knowledge of the relevant Company
performance results could calculate the amount to be paid. Such Performance
Goals may vary by Participant and by grant.

     The number of Common Stock Units and Dividend Equivalents earned will be
equal to the amounts awarded multiplied by the Performance Factor. However, the
Committee shall have the discretion, by Participant and by grant, to reduce (but
not to increase) some or all of the amount that would otherwise be payable by
reason of the satisfaction of the Performance Goals. In making any such
determination, the Committee is authorized to take into account any such factor
or factors it determines are appropriate, including but not limited to Company,
business unit and individual performance.

     6.6  Payment of Common Stock Units and Dividend Equivalent Account. Payment
in respect of Common Stock Units earned (as determined under Sections 6.4 and
6.5) shall be made to the holder thereof within ninety (90) days after the
Performance Period for such units has ended, but only to the extent the
Committee determines that the continuing employment and/or any applicable
performance targets have been met.

     Payment for Common Stock Units earned shall be made in shares of Common
Stock, except as provided in Section 6.9. The number of shares paid shall be
equal to the number of Common Stock Units earned. The holder may elect to reduce
this amount by the number of shares of Common Stock which have, on the date the
Common Stock Units are paid, a fair market value equal to the applicable
federal, state and local withholding tax due on the receipt of Common Stock, in
lieu of making a cash payment equal to the amount of such withholding tax due.

     A holder of Common Stock Units will be entitled to receive payment from the
Company at the end of the Performance Period an amount in cash equal to the
Dividend Equivalent Account earned (as determined under Sections 6.4 and 6.5) by
the holder minus applicable federal, state and local withholding tax due.

     6.7  Death, Disability or Retirement.

               (a)  Upon the termination of a Participant's employment by reason
     of death, or permanent disability or retirement (as each is determined by
     the Committee) prior to the end of the Performance Period:

                                       15
<PAGE>

                    (1) in the case of an award of Common Stock Units made
          pursuant to Section 6.1(a) hereof and conditioned upon the
          Participant's continued employment, the conditions to payout, if any,
          shall be determined by the Committee and shall be as set forth in the
          agreement granting the Common Stock Units.

                    (2) in the case of an award of Common Stock Units made
          pursuant to Section 6.1(b) hereof and conditioned upon the attainment
          of certain predetermined performance objectives, no portion of the
          Participant's Common Stock Unit and the Dividend Equivalent Account
          related to such award shall be forfeited, and the Common Stock Units,
          together with related Dividend Equivalents, shall be paid out as
          though such Participant continued in the employment of the Company
          through any applicable Performance Period, and as, if, and when the
          applicable Performance Goals have been met.

       6.8 Termination of Employment. Except as provided in Sections 6.7 and
6.9, or as determined by the Committee, 100% of all Common Stock Units of a
Participant under the Plan shall be forfeited and the Dividend Equivalent
Account shall be forfeited upon termination of the Participant's employment with
the Company prior to the end of the Performance Period, and in such event the
Participant shall not be entitled to receive any Common Stock or any payment of
the Dividend Equivalent Account regardless of the level of Performance Goals
achieved for the respective Performance Periods.

       6.9 Change in Control. In the event of a Change in Control, all the
Participant's outstanding Common Stock Units shall be payable to the Participant
in cash or stock, as follows:

          (a)  if pooling of interests accounting treatment is to be used with
       respect to such Change in Control, the Participant will receive shares of
       Common Stock equal in number to the total number of Common Stock Units
       granted to such Participant; or

          (b) if pooling of interests accounting treatment is not to be used
       with respect to such Change in Control, the Participant will be paid an
       amount in cash equal to the number of Common Stock Units outstanding
       multiplied by the Market Price as defined in Section 5.4. Such amount
       will be reduced by the applicable federal, state and local withholding
       taxes due.

       The cash or stock, as the case may be, shall be paid out to the
Participant no later than ninety (90) days following the date of occurrence of
such Change in Control (the "CSU Payout Date"), regardless of whether the
applicable Performance Period has expired or whether performance targets have
been met. There will be no adjustment for any Performance Factors described in
Section 6.5.

       On or before the CSU Payout Date, and regardless of whether pooling of
interests accounting treatment is to be used with respect to such Change in
Control, the Participant will be paid an amount in cash equal to the value of
the amounts accrued in the Participant's Dividend Equivalent Account immediately
preceding the Change in Control. Payout of Common Stock Units and the Dividend
Equivalent Account shall be made to each Participant:

          (c) who is employed by the Company on the CSU Payout Date; or

                                       16
<PAGE>

          (d) whose employment relationship with the Company is terminated:

               (1) as a result of any Qualifying Termination prior to the CSU
          Payout Date; or

                2) as a result of death, or permanent disability or retirement
          (as each is determined by the Committee), that has occurred prior to
          the CSU Payout Date.

     The Committee may establish, at the time of the grant of Common Stock
Units, other conditions which must be met for payout to occur. These conditions
shall be set forth in the Committee's resolution granting the Common Stock Units
and in the Agreement with the holder.

                                 Miscellaneous

     7.1 General Restriction. Each award under the Plan shall be subject to the
requirement that if, at any time, the Committee shall determine that:

          (a) the listing, registration or qualification of the shares of Common
     Stock subject or related thereto upon any securities exchange or under any
     state or Federal law; or

          (b) the consent or approval of any government regulatory body; or

          (c) an agreement by the recipient of an award with respect to the
     disposition of shares of Common Stock,

is necessary or desirable as a condition of, or in connection with, the granting
of such award or the issue or purchase of shares of Common Stock thereunder,
then such award may not be consummated in whole or in part unless such listing,
registration, qualification, consent, approval or agreement shall have been
effected or obtained free of any conditions not acceptable to the Committee.

     7.2 Accounting and Tax Treatment for Change in Control. Notwithstanding
anything in this Plan to the contrary, in the event of a Change in Control, the
Committee shall not have the right to take any actions described in the Plan
that would make the Change in Control ineligible for pooling of interests
accounting treatment or that would make the Change in Control ineligible for
desired tax treatment if, in the absence of such right, the Change in Control
would qualify for such treatment and the Company intends to use such treatment
with respect to the Change in Control.

     7.3 Non-Assignability. Awards under the Plan shall not be assignable or
transferable by the recipient thereof, except by will or by the laws of descent
and distribution except as otherwise determined by the Committee. Accordingly,
during the life of the recipient, such award shall be exercisable only by such
person or by such person's guardian or legal representative, unless the
Committee determines otherwise.

     7.4 Right to Terminate Employment. Nothing in the Plan or in any agreement
entered into pursuant to the Plan shall confer upon any Participant the right to
continue in the employment

                                       17
<PAGE>

of the Company or effect any right which the Company may have to terminate the
employment of such Participant.

     7.5  Non-Uniform Determinations. The Committee's determinations under the
Plan (including without limitation, determinations of the persons to receive
awards, the form, amount and timing of such awards, the terms and provisions of
such awards, and the agreements evidencing same) need not be uniform and may be
made by it selectively among persons who receive, or are eligible to receive,
awards under the Plan, whether or not such persons are similarly situated.

     7.6  Rights as a Shareholder. The recipient of any award under the Plan
shall have no rights as a shareholder with respect thereto unless and until
certificates for shares of Common Stock are issued on behalf of such recipient.

     7.7  Leaves of Absence. The Committee shall be entitled to make such rules,
regulations and determinations as it deems appropriate under the Plan in respect
of any leave of absence taken by the recipient of any award. Without limiting
the generality of the foregoing, the Committee shall be entitled to determine
(i) whether or not any such leave of absence shall constitute a termination of
employment within the meaning of the Plan and (ii) the impact, if any, of any
such leave of absence on awards under the Plan theretofore made to any recipient
who takes such leaves of absence.

     7.8  Newly Eligible Employees. The Committee shall be entitled to make such
rules, regulations, determinations and awards as it deems appropriate in respect
of any employee who becomes eligible to participate in the Plan or any portion
thereof after the commencement of an award or incentive period.

     7.9  Adjustments. In any event of any change in the outstanding Common
Stock by reason of a stock dividend or distribution, recapitalization, merger,
consolidation, split-up, combination, exchange of shares or the like, the
Committee may appropriately adjust the number of shares of Common Stock which
may be issued under the Plan, the number of shares of Common Stock subject to
Options theretofore granted under the Plan, the Option Price of Options
theretofore granted under the Plan, the number of Common Stock Units theretofore
awarded under the Plan and any and all other matters deemed appropriate by the
Committee.

     7.10 Amendment of the Plan.

          (a)  The Committee may, without further action by the shareholders and
     without receiving further consideration from the Participants, amend this
     Plan or condition or modify awards under this Plan in response to changes
     in securities or other laws or rules, regulations or regulatory
     interpretations thereof applicable to this Plan or to comply with stock
     exchange rules or requirements.

          (b)  The Committee may at any time, and from time to time, modify or
     amend the Plan in any respect, except that without shareholder approval the
     Committee may not:

                    (1) increase the maximum award levels established in Section
          2.7, including the maximum number of shares of Common Stock which may
          be issued under the Plan (other than increases pursuant to Section
          7.9);

                    (2) extend the term during which an Option may be exercised
          beyond ten years from the date of grant; or

          Section 2.3.

     The termination or any modification or amendment of the Plan, except as
provided in Section 7.10(a) above, shall not without the consent of a
Participant, affect the Participant's rights under an award previously granted.

<PAGE>

          significantly reduce such Participant's benefits under, any employee
          benefit plan or compensation plan in which such Participant was
          participating immediately prior to the Change in Control, provided,
          however, that in the aggregate such actions by the Company

          an extent substantially more burdensome than such Participant's travel
          obligations during the period of twelve (12) consecutive months
          immediately preceding the Change in Control;

     provided, however, that in the case of any such termination of employment
     by the Participant under this subparagraph (b), such termination shall not
     be deemed to be a Qualifying Termination unless the termination occurs
     within 120 days after the occurrence of the event or events constituting
     the reason for the termination; or

          (c) a termination of employment by the Company other than a
     termination for Just Cause, or a termination of employment by the
     Participant for one of the reasons set forth in (b) above, following a
     Potential Change in Control, if the Participant can demonstrate that such
     termination or circumstance in (b) above leading to termination:

                    (1) was at the request of a third party with which the

                                  ARTICLE II

       Background, Purpose and Term of Plan; Participation & Eligibility for
Benefits

     2.1  Background. Effective on December 31, 1991, no further awards shall be
made under the Sunoco, Inc. Long-Term Incentive Plan adopted in June, 1986;
provided, however, that any rights theretofore granted under that plan shall not
be affected.

     2.2  Purpose of the Plan. The purposes of this Sunoco, Inc. Executive Long-
Term Stock Investment Plan (the "Plan") are to:

          (a) better align the interests of shareholders and management of the
     Company by creating a direct linkage between Participants' rewards and
     shareholders' gains;

          (b) provide management with an equity ownership in Sunoco, Inc.
     commensurate with Company performance, as reflected in increased
     shareholder value;

          (c) maintain competitive compensation levels; and

          (d) provide an incentive to management for continuous employment with
     the Company.

     It is intended that most awards made under the Plan will qualify as
performance-based compensation under Section 162(m) of the Code.

     2.3  Term of the Plan. This Plan became effective upon approval by the
holders of a majority of the votes present, in person or represented by proxy,
at the 1991 Annual Meeting of Shareholders of the Company. No awards will be
made under the Plan after December 31, 1996. The Plan and all awards made under
the Plan prior to such date shall remain in effect until such awards have been
satisfied or terminated in accordance with the Plan and the terms of such
awards.

     2.4  Administration. The Plan shall be administered by the Committee which
shall have the authority, in its sole discretion and from time to time to:

          (a) designate the employees or classes of employees eligible to
     participate in the Plan (each such employee being, a "Participant");

          (b) grant awards provided in the Plan in such form and amount as the
     Committee shall determine;

          (c) impose such limitations, restrictions and conditions upon any such
     award as the Committee shall deem appropriate; and

          (d) interpret the Plan, adopt, amend and rescind rules and regulations
     relating to the Plan, and make all other determinations and take all other
     action necessary or advisable for the implementation and administration of
     the Plan.

     The decisions and determinations of the Committee on all matters relating
to the Plan shall be in its sole discretion and shall be conclusive. No member
of the Committee shall be liable for

                                       7
<PAGE>

any action taken or not taken or decision made or not made in good faith
relating to the Plan or any award thereunder.

     2.5  Eligibility for Participation. Participants in the Plan shall be the
officers and other key employees of the Company who occupy responsible
managerial or professional positions and who have the capability of making a
substantial contribution to the success of the Company. In making this selection
and in determining the amount of awards, the Committee shall consider any
factors deemed relevant, including the individual's functions, responsibilities,
value of services to the Company and past and potential contributions to its
profitability and sound growth.

     2.6  Types of Awards Under the Plan. Awards under the Plan may be in the
form of any one or more of the following:

          (a) Stock Options, as described in Article III;

          (b) Incentive Stock Options, as described in Article IV;

          (c) Reload Options, as described in Article V;

          (d) Alternate Appreciation Rights, as described in Article VI;

          (e) Limited Rights, as described in Article VII; and/or

          (f) Common Stock Units, as described in Article VIII.

     2.7  Aggregate Limitation on Awards. Shares of stock which may be issued
under the Plan shall be Common Stock. The maximum number of shares of Common
Stock which may be issued under the Plan shall be 5.8 million. For purposes of
calculating the maximum number of shares of Common Stock which may be issued
under the Plan:

          (a) all the shares issued (including the shares, if any, withheld for
     tax withholding requirements) shall be counted when cash is used as full
     payment for shares issued upon exercise of an Option;

          (b) only the shares issued (including the shares, if any, withheld for
     tax withholding requirements) as a result of an exercise of Alternate
     Appreciation Rights shall be counted;

          (c) only the shares issued (including the shares, if any, withheld for
     tax withholding requirements) net of shares of Common Stock used as full or
     partial payment for such shares upon exercise of an Option; and

          (d) only the shares issued (including the shares, if any, withheld for
     tax withholding) upon vesting and payment of the Common Stock Units, shall
     be counted.

          In addition to shares of Common Stock actually issued pursuant to the
exercise of Options, there shall be deemed to have been issued a number of
shares equal to the number of shares of Common Stock in respect of which Limited
Rights (as described in Article VII) shall have been exercised. Shares tendered
by a Participant as payment for shares issued upon exercise of an Option, shall
be available for issuance under the Plan. Any shares of Common Stock subject to
an Option, which for any reason is terminated unexercised or expires shall again
be available

                                       8
<PAGE>

for issuance under the Plan, but shares subject to an Option which are not
issued as a result of the exercise of Limited Rights shall not be available for
issuance under the Plan.


                                  ARTICLE III

                                 Stock Options

          3.1  Award of Stock Options.  The Committee, from time to time, and
subject to the provisions of the Plan and such other terms and conditions as the
Committee may prescribe, may grant to any Participant in the Plan one or more
options to purchase for cash or shares the number of shares of Common Stock
("Stock Options") allotted by the Committee. The date a Stock Option is granted
shall mean the date selected by the Committee as of which the Committee allots a
specific number of options to a Participant pursuant to the Plan.

          3.2  Stock Option Agreements.  The grant of a Stock Option shall be
evidenced by a written Stock Option Agreement, executed by the Company and the
holder of a Stock Option, stating the number of shares of Common Stock subject
to the Stock Option evidenced thereby, and in such form as the Committee may
from time to time determine.

          3.3  Stock Option Price.  The Option Price per share of Common Stock
deliverable upon the exercise of a Stock Option shall be not less than 100% of
the Fair Market Value of a share of Common Stock on the date the Stock Option is
granted.

          3.4  Term and Exercise.  Each Stock Option shall be fully exercisable
six (6) months from the date of its grant or such longer period as the Committee
shall determine in its discretion and, unless a shorter period is provided by
the Committee or by another Section of this Plan, may be exercised during a
period of ten (10) years from the date of grant thereof. No Stock Option shall
be exercisable after the tenth anniversary of the date of its grant.

          3.5  Manner of Payment.  Each Stock Option Agreement shall set forth
the procedure governing the exercise of the Stock Option granted thereunder, and
shall provide that, upon such exercise in respect of any shares of Common Stock
subject thereto, the Optionee shall pay to the Company, in full, the Option
Price for such shares with cash or with Common Stock. All shares of Common Stock
issued under the Sunoco, Inc. Long-Term Incentive Plan, this Plan, or any
similar executive stock option plan must be held at least six (6) months before
they may be used as payment of the Option Price.

          3.6  Issuance and Delivery of Shares.  As soon as practicable after
receipt of payment, the Company shall deliver to the Optionee a certificate or
certificates for such shares of Common Stock. The Optionee shall become a
shareholder of the Company with respect to Common Stock represented by share
certificates so issued and as such shall be fully entitled to receive dividends,
to vote and to exercise all other rights of a shareholder.

          3.7  Retirement or Disability.  Upon termination of the Optionee's
employment by reason of retirement or Disability (as each is determined by the
Committee), the Optionee may, within sixty (60) months from the date of
termination, exercise any Stock Options to the extent such options are
exercisable during such 60-month period.

                                       9
<PAGE>

          3.8  Termination for Other Reasons.  Except as provided in Sections
3.7 and 3.9, or except as otherwise determined by the Committee, upon
termination of an Optionee's employment, all Stock Options shall terminate:

          (a)  immediately, in the case of an Optionee terminated by the Company
     for Just Cause; or

          (b)  upon the expiration of ninety (90) calendar days following the
     date of termination of an Optionee's employment other than for Just Cause;

provided, however, that the Limited Rights awarded in tandem with such Stock
Options shall not terminate and such Limited Rights shall remain exercisable
during the Exercise Period for any Optionee whose employment relationship with
the Company has been terminated as a result of any Qualifying Termination.

          3.9  Death of Optionee.  Any rights in respect of Stock Options to the
extent exercisable on the date of the Optionee's death may be exercised by the
Optionee's estate or by any person that acquires the legal right to exercise
such Stock Option by bequest, inheritance, or otherwise by reason of the death
of the Optionee. Any such exercise to be valid must occur within the remaining
option term of the Stock Option. The foregoing provisions of this Section 3.9
shall apply to an Optionee who dies while employed by the Company and to an
Optionee whose employment may have terminated prior to death; provided, however,
that:

          (a)  an Optionee who dies while employed by the Company will be
     treated as if the Optionee had retired on the date of death. Accordingly,
     the Optionee's estate or a person who acquires the right to exercise such
     Stock Option by bequest or inheritance will have the right to exercise the
     Stock Option in accordance with Section 3.7; or

          (b)  the estate or a person who acquires the right to exercise a Stock
     Option by bequest or inheritance from an Optionee who dies after
     terminating employment with the Company will have the remainder of any
     exercise period provided under Sections 3.7 and 3.8.

          3.10  Acceleration of Options.  Notwithstanding any provisions to the
contrary in agreements evidencing Options granted thereunder, each outstanding
Option shall become immediately and fully exercisable upon the occurrence of any
Change in Control of Sunoco, Inc.

          3.11  Effect of Exercise.  The exercise of any Stock Options shall
cancel that number of related Limited Rights, if any, which is equal to the
number of shares of Common Stock purchased pursuant to said options.


                                   ARTICLE IV

                            Incentive Stock Options

          4.1  Award of Incentive Stock Options.  The Committee, from time to
time, and subject to the provisions of the Plan and such other terms and
conditions as the Committee may prescribe, grant to any Participant in the Plan
one or more incentive stock options ("Incentive Stock Options") (intended to
qualify as such under the provisions of Section 422 of the Internal

                                       10
<PAGE>

Revenue Code of 1986, as amended (the "Code")) to purchase for cash or shares
the number of shares of Common Stock allotted by the Committee. The date an
Incentive Stock Option is granted shall mean the date selected by the Committee
as of which the Committee allots a specific number of options to a Participant
pursuant to the Plan. Notwithstanding the foregoing, Incentive Stock Options
shall not be granted to any owner of ten percent (10%) or more of the total
combined voting power of the Company and its subsidiaries.

          4.2  Incentive Stock Option Agreements.  The grant of an Incentive
Stock Option shall be evidenced by a written Incentive Stock Option Agreement,
executed by the Company and the holder of an Incentive Stock Option stating the
number of shares of Common Stock subject to the Incentive Stock Option evidenced
thereby, and in such form as the Committee may from time to time determine.

          4.3  Incentive Stock Option Price.  The Option Price per share of
Common Stock deliverable upon the exercise of an Incentive Stock Option shall
not be less than 100% of the Fair Market Value of a share of Common Stock on the
date the Incentive Stock Option is granted.

          4.4  Term and Exercise.  Each Incentive Stock Option shall be fully
exercisable six (6) months from the date of its grant and unless a shorter
period is provided by the Committee or another Section of this Plan, may be
exercised during a period of ten (10) years from the date of grant thereof.  No
Incentive Stock Option shall be exercisable after the tenth anniversary of the
date of its grant.

          4.5  Limits on Incentive Stock Options.  Each Incentive Stock Option
shall provide that, if the aggregate Fair Market Value of the stock on the date
of grant with respect to which Incentive Stock Options are exercisable for the
first time by an Optionee during any calendar year, under this Plan or any other
stock option plan of the Company exceeds One Hundred Thousand Dollars
($100,00.00), then the option, as to the excess shall be treated as a non-
qualified stock option.  An Incentive Stock Option shall not be granted to any
person who is not an "employee" of the Company (within the meaning of Section
424(f) of the Code).

          4.6  Retirement or Disability.  Upon the termination of the Optionee's
employment by reason of retirement or Disability (as each is determined by the
Committee), the Optionee may, within sixty (60) months from the date of such
termination of employment, exercise any Incentive Stock Options to the extent
such Incentive Stock Options are exercisable during such 60-month period.
Notwithstanding the foregoing, the tax treatment available pursuant to Section
422 of the Internal Revenue Code of 1986 upon the exercise of an Incentive Stock
Option will not be available to an Optionee who exercises any Incentive Stock
Option more than:

               (a) twelve (12) months after the date of termination of
          employment due to Disability; or

               (b) three (3) months after the date of termination of employment
          due to retirement.

          4.7  Termination for Other Reasons.  Except as provided in Sections
4.6 and 4.8, or except as otherwise determined by the Committee, upon
termination of an Optionee's employment, all Incentive Stock Options shall
terminate:

               (a) immediately, in the case of an Optionee terminated by the
          Company for Just Cause; and

                                       11
<PAGE>

               (b) upon the expiration of ninety (90) calendar days following
          the date of termination of an Optionee's employment other than for
          Just Cause;

provided, however, that the Limited Rights awarded in tandem with such Stock
Options shall not terminate and such Limited Rights shall remain exercisable
during the Exercise Period for any Optionee whose employment relationship with
the Company has been terminated as a result of any Qualifying Termination.

          4.8  Death of Optionee.  Any rights in respect of Incentive Stock
Options to the extent exercisable on the date of the Optionee's death may be
exercised by the Optionee's estate or by any person that acquires the legal
right to exercise such Stock Option by bequest, inheritance, or otherwise by
reason of the death of the Optionee.  Any such exercise to be valid must occur
within the remaining option term of the Incentive Stock Option.  The foregoing
provisions of this Section 4.8 shall apply to an Optionee who dies while
employed by the Company and to an Optionee whose employment may have terminated
prior to death; provided, however, that:

               (a) an Optionee who dies while employed by the Company will be
          treated as if the Optionee had retired on the date of death.
          Accordingly, the Optionee's estate or a person who acquires the right
          to exercise such Incentive Stock Option by bequest or inheritance will
          have the right to exercise the Incentive Stock Option in accordance
          with Section 4.6; or

               (b) the estate or a person who acquires the right to exercise a
          Stock Option by bequest or inheritance from an Optionee who dies after
          terminating employment with the Company will have the remainder of any
          exercise period provided under Section 4.6 and 4.7.

          4.9  Applicability of Stock Options Selections. The following Sections
of this Plan that apply to Stock Options shall apply equally to Incentive Stock
Options:

               (a) Section 3.5 (Manner of Payment);

               (b) Section 3.6 (Issuance and Delivery of Shares);

               (c) Section 3.10 (Acceleration of Options); and

               (d) Section 3.11 (Effect of Exercise).

          Said Sections are incorporated by reference in this Article IV as
though fully set forth herein.

                                   ARTICLE V

                                 Reload Options

          5.1  Authorization of Reload Options.  Concurrently with the award of
Stock Options and/or the award of Incentive Stock Options to any Participant in
the Plan, the Committee may authorize reload options ("Reload Options") to
purchase for cash or shares a number of shares of Common Stock.  The number of
Reload Options shall equal:

                                       12
<PAGE>

               (a) the number of shares of Common Stock used to exercise the
          underlying Stock Options or Incentive Stock Options; and

               (b) to the extent authorized by the Committee, the number of
          shares of Common Stock used to satisfy any tax withholding requirement
          incident to the exercise of the underlying Stock Options or Incentive
          Stock Options.

          The grant of a Reload Option will be effected upon the exercise of
underlying Stock Options, Incentive Stock Options or Reload Options through the
use of shares of Common Stock held by the Optionee for at least twelve (12)
months.  Notwithstanding the fact that the underlying Option may be an Incentive
Stock Option, a Reload Option is not intended to qualify as an "incentive stock
option" under Section 422 of the Internal Revenue Code of 1986.

          5.2  Reload Option Amendment.  Each Stock Option Agreement and
Incentive Stock Option Agreement shall state whether the Committee has
authorized Reload Options with respect to the underlying Stock Options and/or
Incentive Stock Options.  Upon the exercise of an underlying Stock Option,
Incentive Stock Option or other Reload Option, the Reload Option will be
evidenced by an amendment to the underlying Stock Option Agreement or Incentive
Stock Option Agreement.

          5.3  Reload Option Price.  The Option Price per share of Common Stock
deliverable upon the exercise of a Reload Option shall be the Fair Market Value
of a share of Common Stock on the date of grant of the Reload Option.

          5.4  Term and Exercise.  Each Reload Option is fully exercisable six
(6) months from the effective date of grant.  The term of each Reload Option
shall be equal to the remaining option term of the underlying Stock Option
and/or Incentive Stock Option.  No additional Reload Options may be authorized
in connection with the award of Stock Options or Incentive Stock Options on or
after October 1, 1996.

          5.5  Termination of Employment.  No additional Reload Options shall be
granted to an Optionee when Stock Options, Incentive Stock Options and/or Reload
Options are exercised pursuant to the terms of this Plan following termination
of such Optionee's employment.

          5.6  Applicability of Stock Options Sections.  The following Sections
of this Plan that apply to Stock Options shall apply equally to Reload Options:

               (a) Section 3.5 (Manner of Payment);

               (b) Section 3.6 (Issuance and Delivery of Shares);

               (c) Section 3.7 (Retirement or Disability);

               (d) Section 3.8 (Termination for Other Reasons);

               (e) Section 3.9 (Death of Optionee); and

               (f) Section 3.11 (Effect of Exercise).

                                       13

          Said Sections are incorporated by reference in this Article V as
though fully set forth herein.


                                   ARTICLE VI

                         Alternate Appreciation Rights

          6.1  Award of Alternate Appreciation Rights.  Concurrently with or
subsequent to the award of any Stock Option, Incentive Stock Option or Reload
Option to purchase one or more shares of Common Stock, the Committee may,
subject to the provisions of the Plan and such other terms and conditions as the
Committee may prescribe, award to the Optionee with respect to each share of
Common Stock, a related stock appreciation right ("Alternate Appreciation
Right"), permitting the Optionee to be paid the appreciation on the Option in
lieu of exercising the Option.

          6.2  Alternate Appreciation Rights Agreement.  Alternate Appreciation
Rights shall be evidenced by written agreements in such form as the Committee
may from time to time determine.

          6.3  Exercise.  An Optionee who has been granted Alternate
Appreciation Rights may, from time to time, in lieu of the exercise of an equal
number of Options, elect to exercise one or more Alternate Appreciation Rights
and thereby become entitled to receive from the Company payment in Common Stock
the number of shares determined pursuant to Sections 6.4 and 6.5 hereof.
Alternate Appreciation Rights shall be exercisable only to the same extent and
subject to the same conditions as the Options related thereto are exercisable,
as provided in this Plan.  The Committee may, in its discretion, prescribe
additional conditions to the exercise of any Alternate Appreciation Rights.

          6.4  Amount of Payment.  The amount of payment to which an Optionee
shall be entitled upon the exercise of each Alternate Appreciation Right shall
be equal to 100% of the amount, if any, by which the Fair Market Value of a
share of Common Stock on the exercise date exceeds the Fair Market Value of a
share of Common Stock on the date the Option related to said Alternate
Appreciation Right was granted.

          6.5  Form of Payment.  The number of shares to be paid shall be
determined by dividing the amount of payment determined pursuant to Section 6.4
by the Fair Market Value of a share of Common Stock on the exercise date of such
Alternate Appreciation Rights.  As soon as practicable after exercise, the
Company shall deliver to the Optionee a certificate or certificates for such
shares of Common Stock.  All such shares shall be issued with the rights and
restrictions specified in Section 3.6 of this Plan.

          6.6  Effect of Exercise.  The exercise of any Alternate Appreciation
Rights shall cancel an equal number of Stock Options, Incentive Stock Options,
Reload Options and Limited Rights, if any, related to said Alternate
Appreciation Rights.

          6.7  Retirement or Disability.  Upon termination of the Optionee's
employment by reason of retirement or Disability (as each is determined by the
Committee), the Optionee may, within six (6) months from the date of such
termination, exercise any Alternate Appreciation Rights to the extent such
Alternate Appreciation Rights are exercisable during such six-month period.

                                       14
<PAGE>

          6.8  Death of Optionee or Termination for Other Reasons.  Except as
provided in Section 6.7, or except as otherwise determined by the Committee, all
Alternate Appreciation Rights shall terminate upon the termination of the
Optionee's employment or upon the death of the Optionee.


                                  ARTICLE VII

                                 Limited Rights

          7.1  Award of Limited Rights.  Concurrently with or subsequent to the
award of any Option, the Committee may, subject to the provisions of the Plan
and such other terms and conditions as the Committee may prescribe, award to the
Optionee with respect to each Option, a related limited right permitting the
Optionee, during a specified limited time period, to be paid the appreciation on
the Option in lieu of exercising the Option ("Limited Right").

          7.2  Limited Rights Agreement.  Limited Rights granted under the Plan
shall be evidenced by written agreements in such form as the Committee may from
time to time determine.

          7.3  Exercise Period.  Limited Rights are immediately exercisable in
full upon grant for a period of up to seven (7) months following the date of a
Change in Control (the "Exercise Period").

          7.4  Amount of Payment.  The amount of payment to which an Optionee
shall be entitled upon the exercise of each Limited Right shall be equal to 100%
of the amount, if any, which is equal to the difference between the Option Price
of the related Option and the Market Price of a share of such Common Stock.
Market Price is defined to be the greater of:

               (a) the highest price per share of Common Stock paid, in
          connection with any Change in Control, during the period from the date
          of occurrence of a Potential Change in Control through the ninetieth
          (90th day following the subsequent related Change in Control; and

               (b) the highest price per share of Common Stock reflected in the
          consolidated trading tables of The Wall Street Journal (presently the
          New York Stock Exchange Composite Transactions quotations) during the
          60-day period prior to the Change in Control.

          7.5  Form of Payment.  Payment of the amount to which an Optionee is
entitled upon the exercise of Limited Rights, as determined pursuant to Section
7.4, shall be made solely in cash.

          7.6  Effect of Exercise.  If Limited Rights are exercised, the Options
and Alternate Appreciation Rights, if any, related to such Limited Rights cease
to be exercisable to the extent of the number of shares with respect to which
the Limited Rights were exercised.  Upon the exercise or termination of the
Options and Alternate Appreciation Rights, if any, related to such Limited
Rights, the Limited Rights granted with respect thereto terminate to the extent
of the number of shares as to which the related Options and/or Alternate
Appreciation Rights were exercised or terminated; provided, however, that with
respect to Options and/or Alternate Appreciation Rights that are terminated as a
result of the termination of the Optionee's employment status, the Limited

                                       15
<PAGE>

Rights awarded in tandem therewith shall not terminate and such Limited Rights
shall remain exercisable during the Exercise Period for any Optionee whose
employment relationship with the Company has been terminated as a result of any
Qualifying Termination.

          7.7  Retirement or Disability.  Upon termination of the Optionee's
employment by reason of Disability or retirement (as each is determined by the
Committee), the Optionee may, within six (6) months from the date of
termination, exercise any Limited Rights to the extent such Limited Right is
exercisable during such six-month period.

          7.8  Death of Optionee or Termination for Other Reasons.  Except as
provided in Sections 7.7 and 7.9 or except as otherwise determined by the
Committee, all Limited Rights granted under the Plan shall terminate upon the
termination of the Optionee's employment or upon the death of the Optionee.

          7.9  Termination Related to a Change in Control.  The requirement that
an Optionee be terminated by reason of retirement or Disability or be employed
by the Company at the time of exercise pursuant to Sections 7.7 and 7.8
respectively, is waived during the Exercise Period as to any Optionee whose
employment relationship with the Company has been terminated as a result of any
Qualifying Termination.


                                  ARTICLE VIII

                               Common Stock Units

          8.1  Award of Common Stock Units.  The Committee, from time to time,
and subject to the provisions of the Plan, may grant to any Participant in the
Plan rights to receive shares of Common Stock which are subject to a risk of
forfeiture by the Participant ("Common Stock Units").  At the time it grants any
Common Stock Units, the Committee shall determine whether the payment of such
Common Stock Units shall be conditioned upon either:

               (a) the Participant's continued employment with the Company
          throughout a stated period (Section 8.4); or

               (b) the attainment of certain predetermined performance
          objectives during a stated period (Section 8.5).

          The date Common Stock Units are granted shall mean the date selected
by the Committee as of which the Committee allots a specific number of Common
Stock Units to a Participant pursuant to the Plan.

          8.2  Common Stock Unit Agreements.  Common Stock Units granted under
the Plan shall be evidenced by written agreements stating the number of Common
Stock Units evidenced thereby or in such form and as the Committee may from time
to time determine.

          8.3  Dividend Equivalents.  A holder of Common Stock Units will be
entitled to receive payment from the Company in an amount equal to each cash
dividend ("Dividend Equivalent") the Company would have paid to such holder had
he, on the record date for payment of such dividend, been the holder of record
of shares of Common Stock equal to the number of Common Stock Units which had
been awarded to such holder as of the close of business on such record

                                       16
<PAGE>

date. The Company shall establish a bookkeeping account on behalf of each
Participant in which the Dividend Equivalents that would have been paid to the
holder of Common Stock Units ("Dividend Equivalent Account") shall be credited.
The Dividend Equivalent Account will not bear interest.

          8.4  Performance Period.  Upon making an award, the Committee shall
determine (and the Common Stock Unit Agreement shall state) the length of the
applicable period during which employment must be maintained or certain
performance targets must be attained (the "Performance Period").  Performance
Periods will normally be from three to five years; provided, however, the
Committee at its sole discretion may establish other time periods.

          8.5  Performance Goals.  Common Stock Units and the related Dividend
Equivalent Account earned may be based upon the attainment of Performance Goals
established by the Committee in accordance with Section 162(m).  Within the
first ninety (90) days of the Performance Period, the Committee shall establish,
in writing, the weighted Performance Goals and related Performance Factors for
various goal achievement levels for the Company.  In establishing the weighted
Performance Goals, the Committee shall take the necessary steps to insure that
the Company's ability to achieve the pre-established goals is uncertain at the
time the goals are set.  The established written Performance Goals, assigned
weights, and Performance Factors shall be written in terms of an objective
formula, whereby any third party having knowledge of the relevant Company
performance results could calculate the amount to be paid.  Such Performance
Goals may vary by Participant and by grant.

          The number of Common Stock Units and Dividend Equivalents earned will
be equal to the amounts awarded multiplied by the Performance Factor. However,
the Committee shall have the discretion, by Participant and by grant, to reduce
(but not to increase) some or all of the amount that would otherwise be payable
by reason of the satisfaction of the Performance Goals.  In making any such
determination, the Committee is authorized to take into account any such factor
or factors it determines are appropriate, including but not limited to Company,
business unit and individual performance.

          8.6  Payment of Common Stock Units and Dividend Equivalent Account.
Payment in respect of Common Stock Units earned (as determined under Sections
8.4 and 8.5) shall be made to the holder thereof within ninety (90) days after
the Performance Period for such units has ended, but only to the extent the
Committee determines that the continuing employment and/or any applicable
performance targets have been met.

          Payment for Common Stock Units earned shall be made in shares of
Common Stock, except as provided in Section 8.9.  The number of shares paid
shall be equal to the number of Common Stock Units earned.  The holder may elect
to reduce this amount by the number of shares of Common Stock which have, on the
date the Common Stock Units are paid, a fair market value equal to the
applicable federal, state and local withholding tax due on the receipt of Common
Stock, in lieu of making a cash payment equal to the amount of such withholding
tax due.  A holder of Common Stock Units will be entitled to receive payment
from the Company at the end of the Performance Period an amount in cash equal to
the Dividend Equivalent Account earned (as determined under Sections 8.4 and
8.5) by the holder minus applicable federal, state and local withholding tax
due.

                                       17

          8.7  Death, Disability or Retirement.

               (a)  Upon the termination of Participant's employment by reason
          of death, or permanent disability or retirement (as each is determined
          by the Committee) prior to the end of the Performance Period:

                    (1)  in the case of an award of Common Stock Units made
               pursuant to Section 8.1(a) hereof and conditioned upon the
               Participant's continued employment, the conditions to payout, if
               any, shall be determined by the Committee and shall be as set
               forth in the agreement granting the Common Stock Units.

                    (2)  in the case of an award of Common Stock Units made
               pursuant to Section 8.1(b) hereof and conditioned upon the
               attainment of certain predetermined performance objectives, no
               portion of the Participant's Common Stock Unit and the Dividend
               Equivalent Account related to such award shall be forfeited, and
               the Common Stock Units, together with related Dividend
               Equivalents, shall be paid out as though such Participant
               continued in the employment of the Company through any applicable
               Performance Period, and as, if, and when the applicable
               Performance Goals have been met.

          8.8  Termination of Employment.  Except as provided in Sections 8.7
and 8.9, or as determined by the Committee, 100% of all Common Stock Units of a
Participant under the Plan shall be forfeited and the Dividend Equivalent
Account shall be forfeited upon termination of the Participant's employment with
the Company prior to the end of the Performance Period, and in such event the
Participant shall not be entitled to receive any Common Stock or any payment of
the Dividend Equivalent Account regardless of the level of Performance Goals
achieved for the respective Performance Periods.

          8.9  Change in Control.  The number of Common Stock Units earned by
the Participant shall be determined by multiplying:

               (a) the total number of all the Participant's granted and
          outstanding Common Stock Units; by

               (b) a percentage equal to:

                    (1) the number of full and partial calendar months which the
               Common Stock Units have been outstanding as of the date of the
               Change in Control; divided by

                    (2) the number of full and partial calendar months in the
               applicable Performance Period.

          In the event of a Change in Control, the Common Stock Units earned by
the Participant shall be payable to the Participant in cash or stock, as
follows:

               (c) if pooling of interests accounting treatment is to be used
          with respect to such Change in Control, the Participant will receive
          shares of Common Stock equal in number to the number of Common Stock
          Units earned by such Employee; or

                                       18
<PAGE>

               (d) if pooling of interests accounting treatment is not to be
          used with respect to such Change in Control, the Participant will be
          paid an amount in cash equal to the number of Common Stock Units
          earned by such Participant outstanding multiplied by the Market Price
          as defined in Section 7.4. Such amount will be reduced by the
          applicable federal, state and local withholding taxes due.

          The cash or stock, as the case may be, shall be paid out to the
Participant no later than ninety (90) days following the date of occurrence of
such Change in Control (the "CSU Payout Date"), regardless of whether the
applicable Performance Period has expired or whether performance targets have
been met.  There will be no adjustment for any Performance Factors described in
Section 8.5.

          On or before the CSU Payout Date, and regardless of whether pooling of
interests accounting treatment is to be used with respect to such Change in
Control, the Participant will be paid an amount in cash equal to the value of
the amounts accrued in the Participant's Dividend Equivalent Account immediately
preceding the Change in Control.  Payout of Common Stock Units and the Dividend
Equivalent Account shall be made to each Participant:

               (e) who is employed by the Company on the CSU Payout Date; or

               (f) whose employment relationship with the Company is terminated:

                    (1) as a result of any Qualifying Termination prior to the
               CSU Payout Date; or

                    (2) as a result of death or permanent disability or
               retirement (as each is determined by the Committee), that has
               occurred prior to the CSU Payout Date.

          The Committee may establish, at the time of the grant of Common Stock
Units, other conditions which must be met for payout to occur.  These conditions
shall be set forth in the Committee's resolution granting the Common Stock Units
and in the Agreement with the holder.


                                   ARTICLE IX

                                 Miscellaneous

          9.1  General Restriction.  Each award under the Plan shall be subject
to the requirement that, if at any time the Committee shall determine that:

               (a) the listing, registration or qualification of the shares of
          Common Stock subject or related thereto upon any securities exchange
          or under any state or Federal law; or

               (b) the consent or approval of any government regulatory body; or

               (c) an agreement by the recipient of an award with respect to the
          disposition of shares of Common Stock,

is necessary or desirable as a condition of, or in connection with, the granting
of such award or the issue or purchase of shares of Common Stock thereunder,
then such award may not be

                                       19
<PAGE>

consummated in whole or in part unless such listing, registration,
qualification, consent, approval or agreement shall have been effected or
obtained free of any conditions not acceptable to the Committee.

          9.2  Accounting and Tax Treatment for Change in Control.
Notwithstanding anything in this Plan to the contrary, in the event of a Change
in Control, the Committee shall not have the right to take any actions described
in the Plan that would make the Change in Control ineligible for pooling of
interests accounting treatment or that would make the Change in Control
ineligible for desired tax treatment if, in the absence of such right, the
Change in Control would qualify for such treatment and the Company intends to
use such treatment with respect to the Change in Control.

          9.3  Non-Assignability.  Awards under the Plan shall not be assignable
or transferable by the recipient thereof, except by will or by the laws of
descent and distribution except as otherwise determined by the Committee.
Accordingly, during the life of the recipient, such award shall be exercisable
only by such person or by such person's guardian or legal representative, unless
the Committee determines otherwise.

          9.4  Right to Terminate Employment.  Nothing in the Plan or in any
agreement entered into pursuant to the Plan shall confer upon any Participant
the right to continue in the employment of the Company or effect any right which
the Company may have to terminate the employment of such Participant.

          9.5  Non-Uniform Determinations.  The Committee's determinations under
the Plan (including without limitation, determinations of the persons to receive
awards, the form, amount and timing of such awards, the terms and provisions of
such awards, and the agreements evidencing same) need not be uniform and may be
made by it selectively among persons who receive, or are eligible to receive,
awards under the Plan, whether or not such persons are similarly situated.

          9.6  Rights as a Shareholder.  The recipient of any award under the
Plan shall have no rights as a shareholder with respect thereto unless and until
certificates for shares of Common Stock are issued on behalf of such recipient.

          9.7  Leaves of Absence.  The Committee shall be entitled to make such
rules, regulations and determinations as it deems appropriate under the Plan in
respect of any leave of absence taken by the recipient of any award.  Without
limiting the generality of the foregoing, the Committee shall be entitled to
determine:

               (a) whether or not any such leave of absence shall constitute a
          termination of employment within the meaning of the Plan; and

               (b) the impact, if any, of any such leave of absence on awards
          under the Plan theretofore made to any recipient who takes such leaves
          of absence.

          9.8  Newly Eligible Employees.  The Committee shall be entitled to
make such rules, regulations, determinations and awards as it deems appropriate
in respect of any employee who becomes eligible to participate in the Plan or
any portion thereof after the commencement of an award or incentive period.

                                       20
<PAGE>

          9.9  Adjustments.  In any event of any change in the outstanding
Common Stock by reason of a stock dividend or distribution, recapitalization,
merger, consolidation, split-up, combination, exchange of shares or the like,
the Committee may appropriately adjust the number of shares of Common Stock
which may be issued under the Plan, the number of shares of Common Stock subject
to Options theretofore granted under the Plan, the Option Price of Options
theretofore granted under the Plan, the number of Common Stock Units theretofore
awarded under the Plan and any and all other matters deemed appropriate by the
Committee.

          9.10 Amendment of the Plan.

               (a) The Committee may, without further action by the shareholders
          and without receiving further consideration from the Participants,
          amend this Plan or condition or modify awards under this Plan in
          response to changes in securities or other laws or rules, regulations
          or regulatory interpretations thereof applicable to this Plan or to
          comply with stock exchange rules or requirements;

               (b) The Committee may at any time, and from time to time, modify
          or amend the Plan in any respect, except that without shareholder
          approval the Committee may not:

                    (1) increase the maximum number of shares of Common Stock
               which may be issued under the Plan (other than increases pursuant
               to Section 9.9);

                    (2) extend the term during which any award may be granted or
               exercised; or

                    (3) extend the term of the Plan.

          The termination or any modification or amendment of the Plan, except
as provided in Section 9.10(a) above, shall not without the consent of a
Participant, affect the Participant's rights under an award previously granted.

               except in connection with such Participant's:

                         (i)  assignment to a new position at a higher combined

               Participant's annual base salary or guideline (target) bonus as
               in effect immediately prior to the Change in Control; the failure
               by the Company to continue in effect, or the taking of any action
               by the Company that would adversely affect such Participant's
               participation in or significantly reduce such Participant's
               benefits under, any employee benefit plan or compensation plan in
               which such Participant was participating immediately prior to the
               Change in Control, provided, however, that in the aggregate such
               actions by the Company significantly reduce the Participant's
               total compensation (i.e., the sum of Participant's annual base
               salary, guideline (target) bonus, and the aggregate value to the
               Participant of all employee benefit and compensation plans); or
               the failure by the Company, without the Participant's consent, to
               pay to the Participant any portion of the Participant's current
               compensation, or to pay to the Participant any portion of an
               installment of deferred compensation under any deferred
               compensation program of the Company; or

                    (4) The Company requires the Participant to be based
               anywhere other than the Participant's present work location or a
               location within thirty-five (35) miles from the present location;
               or the Company requires the Participant to travel on Company
               business to an extent substantially more burdensome than such
               Participant's travel obligations during the period of twelve (12)
               consecutive months immediately preceding the Change in Control;

          provided, however, that in the case of any such termination of
          employment by the Participant under this subparagraph (b), such
          termination shall not be deemed to be a Qualifying Termination unless
          the termination occurs within 120 days after the occurrence of the
          event or events constituting the reason for the termination; or

               (c) a termination of employment by the Company other than a
          termination for Just Cause, or a termination of employment by the
          Participant for one of the reasons set forth in (b) above, following a
          Potential Change in Control, if the Participant can demonstrate that
          such termination or circumstance in (b) above leading to termination:

               anticipation of, a Change in Control;

          provided, however, that in either such case, such Change in Control
          actually occurs within one (1) year following the Employment
          Termination Date.

                                  ARTICLE II

             Background, Purpose and Term of Plan; Participation & Eligibility
for Benefits

          2.1   Background.  Effective on December 31, 1986, no further awards
shall be made under the Sunoco, Inc. Executive Long-Term Incentive Plan adopted
in June, 1978 provided, however, that any rights theretofore granted under that
plan shall not be affected.

          2.2   Purpose of the Plan. The purposes of this Sunoco, Inc. Long-Term
Incentive Plan (the "Plan") are to:

                (a) more closely associate the interests of the Company with the
          shareholders by relating capital accumulation with increases in
          shareholder value;

               (b) encourage management success by providing capital
          accumulation as an incentive;

               (c) maintain competitive compensation levels; and

               (d) provide an incentive to management for continuous employment
          with the Company.

          It is intended that most awards made under the Plan qualify as
performance-based compensation under Section 162(m) of the Code.

          2.3   Term of the Plan.  This Plan became effective upon approval by
the holders of a majority of the votes present, in person or represented by
proxy, at the 1986 Annual Meeting of

                                       6
<PAGE>

Shareholders of the Company. No awards will be made under the Plan after
December 31, 1991. The Plan and all awards made under the Plan prior to such
date shall remain in effect until such awards have been satisfied or terminated
in accordance with the Plan and the terms of such awards.

          2.4   Administration.  The Plan shall be administered by the Committee
which shall have the authority, in its sole discretion and from time to time to:

                (a) designate the employees or classes of employees eligible to
          participate in the Plan (each such employee being, a "Participant");

                (b) grant awards provided in the Plan in such form and amount as
          the Committee shall determine;

                (c) impose such limitations, restrictions and conditions upon
          any such award as the Committee shall deem appropriate; and

                (d) interpret the Plan, adopt, amend and rescind rules and
          regulations relating to the Plan, and make all other determinations
          and take all other action necessary or advisable for the
          implementation and administration of the Plan.

          The decisions and determinations of the Committee on all matters
relating to the Plan shall be in its sole discretion and shall be conclusive.
No member of the Committee shall be liable for any action taken or not taken or
decision made or not made in good faith relating to the Plan or any award
thereunder.

          2.5   Eligibility for Participation. Participants in the Plan shall be
the officers and other key employees of the Company who occupy responsible
managerial or professional positions and who have the capability of making a
substantial contribution to the success of the Company. In making this selection
and in determining the amount of awards, the Committee shall consider any
factors deemed relevant, including the individual's functions, responsibilities,
value of services to the Company and past and potential contributions to its
profitability and sound growth.

          2.6   Types of Awards Under the Plan.  Awards under the Plan may be in
the form of any one or more of the following:

                (a) Stock Options, as described in Article III;

                (b) Alternate Appreciation Rights, as described in Article IV;

                (c) Limited Rights, as described in Article V; and/or

                (d) Restricted Stock Units, as described in Article VI.

          2.7   Aggregate Limitation on Awards.  Shares of stock which may be
issued under the Plan shall be Common Stock.  The maximum number of shares of
Common Stock which may be issued under the Plan shall be three million
(3,000,000).  For purposes of calculating the maximum number of shares of Common
Stock which may be issued under the Plan:

                                       7
<PAGE>

                (a) all the shares issued (including the shares, if any,
          withheld for tax withholding requirements) shall be counted when cash
          is used as full payment for shares issued upon exercise of a Stock
          Option;

                (b) only the shares issued (including the shares, if any,
          withheld for tax withholding requirements) net of shares of Common
          Stock used as full or partial payment for such shares upon exercise of
          a Stock Option, shall be counted; and

                (c) only the shares issued (including the shares, if any,
          withheld for tax withholding) upon vesting and payment of the
          Restricted Stock Units, shall be counted.

          In addition to shares of Common Stock actually issued pursuant to the
exercise of Stock Options, there shall be deemed to have been issued a number of
shares equal to the number of shares of Common Stock in respect of which
Alternate Appreciation Rights and Limited Rights shall have been exercised.
Shares tendered by a Participant as payment for shares issued upon exercise of a
Stock Option, shall be available for issuance under the Plan.  Any shares of
Common Stock subject to a Stock Option, which for any reason is terminated
unexercised or expires shall again be available for issuance under the Plan, but
shares subject to a Stock Option which are not issued as a result of the
exercise of Alternate Appreciation Rights or Limited Rights shall not be
available for issuance under the Plan.

                                  ARTICLE III

                                 Stock Options

          3.1   Award of Stock Options.  The Committee, from time to time, and
subject to the provisions of the Plan and such other terms and conditions as the
Committee may prescribe, may grant to any Participant in the Plan one or more
options to purchase for cash or shares the number of shares of Common Stock
("Stock Options") allotted by the Committee.  The date a Stock Option is granted
shall mean the date selected by the Committee as of which the Committee allots a
specific number of options to a Participant pursuant to the Plan.

          3.2   Stock Option Agreements.  The grant of a Stock Option shall be
evidenced by a written Stock Option Agreement, executed by the Company and the
holder of a Stock Option, stating the number of shares of Common Stock subject
to the Stock Option evidenced thereby, and in such form as the Committee may
from time to time determine.

          3.3   Stock Option Price.  The Option Price per share of Common Stock
deliverable upon the exercise of a Stock Option shall be not less than 100% of
the Fair Market Value of a share of Common Stock on the date the Stock Option is
granted.

          3.4   Term and Exercise.  Except as provided in Section 3.10 hereof,
and unless otherwise determined by the Committee, each Stock Option granted
under the Plan shall become exercisable with respect to twenty-five percent
(25%) of the shares subject thereto on the first anniversary of the date of
grant thereof, and with respect to an additional twenty-five percent (25%) of
such shares on each of the second, third and fourth anniversaries of such date
of grant. Stock Options may be partially exercised from time to time within such
percentage limitations. Stock Options granted under the Plan shall be
exercisable during such period or periods as the Committee shall determine;
provided, however, that no Stock Option shall be exercisable more than ten (10)
years after the date of grant thereof.

                                       8
<PAGE>

          3.5   Manner of Payment.  Each Stock Option Agreement shall set forth
the procedure governing the exercise of the Stock Option granted thereunder, and
shall provide that, upon such exercise in respect of any shares of Common Stock
subject thereto, the Optionee shall pay to the Company, in full, the Option
Price for such shares with cash or with previously owned Common Stock.
Notwithstanding the foregoing, if previously owned Common Stock is used in
payment of the Option Price, the Optionee may not use the shares received upon
such exercise to immediately satisfy the exercise price of additional Stock
Options.

          3.6   Issuance and Delivery of Shares.  As soon as practicable after
receipt of payment, the Company shall deliver to the Optionee a certificate or
certificates for such shares of Common Stock.  The Optionee shall become a
shareholder of the Company with respect to Common Stock represented by share
certificates so issued and as such shall be fully entitled to receive dividends,
to vote and to exercise all other rights of a shareholder.

          3.7   Retirement or Disability.  Upon termination of the Optionee's
employment by reason of retirement or Disability (as each is determined by the
Committee), the Optionee may, within sixty (60) months from the date of
termination, exercise any Stock Options to the extent such options are
exercisable during such 60-month period.

          3.8   Termination for Other Reasons.  Except as provided in Sections
3.7 and 3.9, or except as otherwise determined by the Committee, upon
termination of an Optionee's employment; all Stock Options shall terminate:

                (a)  immediately, in the case of an Optionee terminated by the
Company for Just Cause; and

                (b)  upon the expiration of ninety (90) calendar days following
the date of termination of an Optionee's employment other than for Just Cause;

provided, however, that the Limited Rights awarded in tandem with such Stock
Options shall not terminate and such Limited Rights shall remain exercisable
during the Exercise Period for any Optionee whose employment relationship with
the Company has been terminated as a result of any Qualifying Termination.

          3.9   Death of Optionee.  Any rights in respect of Stock Options to
the extent exercisable on the date of the Optionee's death may be exercised by
the Optionee's estate or by any person that acquires the legal right to exercise
such Stock Option by bequest, inheritance, or otherwise by reason of the death
of the Optionee. Any such exercise to be valid must occur within the remaining
option term of the Stock Option. The foregoing provisions of this Section 3.9
shall apply to an Optionee who dies while employed by the Company and to an
Optionee whose employment may have terminated prior to death; provided, however,
that:

                (a) an Optionee who dies while employed by the Company will be
          treated as if the Optionee had retired on the date of death.
          Accordingly, the Optionee's estate or a person who acquires the right
          to exercise such Stock Option by bequest or inheritance will have the
          right to exercise the Stock Option in accordance with Section 3.7; or

                (b) the estate or a person who acquires the right to exercise a
          stock option by bequest or inheritance from an Optionee who dies after
          terminating employment with the Company will have the remainder of any
          exercise period provided under Sections 3.7 and 3.8.

                                       9
<PAGE>

          3.10  Acceleration of Options.  Notwithstanding any provisions to the
contrary in agreements evidencing Options granted thereunder, each outstanding
Option shall become immediately and fully exercisable upon the occurrence of any
Change in Control of Sunoco, Inc.

          3.11  Effect of Exercise.  The exercise of any Stock Options shall
cancel that number of related Alternate Appreciation Rights, if any, and Limited
Rights, if any, which is equal to the number of shares of Common Stock purchased
pursuant to said options.


                                  ARTICLE IV

                         Alternate Appreciation Rights

          4.1   Award of Alternate Appreciation Rights.  Concurrently with or
subsequent to the award of any Stock Option to purchase one or more shares of
Common Stock, the Committee may, subject to the provisions of the Plan and such
other terms and conditions as the Committee may prescribe, award to the Optionee
with respect to each share of Common Stock, a related stock appreciation right
("Alternate Appreciation Right"), permitting the Optionee to be paid the
appreciation on the Stock Option in lieu of exercising the Stock Option.

          4.2   Alternate Appreciation Rights Agreement.  Alternate Appreciation
Rights shall be evidenced by written agreements in such form as the Committee
may from time to time determine.

          4.3   Exercise.  An Optionee who has been granted Alternate
Appreciation Rights may, from time to time, in lieu of the exercise of an equal
number of Stock Options, elect to exercise one or more Alternate Appreciation
Rights and thereby become entitled to receive from the Company payment in Common
Stock the number of shares determined pursuant to Sections 4.4 and 4.5 hereof.
Alternate Appreciation Rights shall be exercisable only to the same extent and
subject to the same conditions as the Stock Options related thereto are
exercisable, as provided in this Plan.  The Committee may, in its discretion,
prescribe additional conditions to the exercise of any Alternate Appreciation
Rights.

          4.4   Amount of Payment.  The amount of payment to which an Optionee
shall be entitled upon the exercise of each Alternate Appreciation Right shall
be equal to 100% of the amount, if any, by which the Fair Market Value of a
share of Common Stock on the exercise date exceeds the Fair Market Value of a
share of Common Stock on the date the Stock Option related to said Alternate
Appreciation Right was granted.

          4.5   Form of Payment.  The number of shares to be paid shall be
determined by dividing the amount of payment determined pursuant to Section 4.4
by the Fair Market Value of a share of Common Stock on the exercise date of such
Alternate Appreciation Rights.  As soon as practicable after exercise, the
Company shall deliver to the Optionee a certificate or certificates for such
shares of Common Stock.  All such shares shall be issued with the rights and
restrictions specified in Section 3.6 of this Plan.

          4.6   Effect of Exercise.  The exercise of any Alternate Appreciation
Rights shall cancel an equal number of Stock Options and Limited Rights, if any,
related to said Alternate Appreciation Rights.

                                       10
<PAGE>

          4.7   Retirement or Disability.  Upon termination of the Optionee's
employment by reason of retirement or Disability (as each is determined by the
Committee), the Optionee may, within six (6) months from the date of such
termination, exercise any Alternate Appreciation Rights to the extent such
Alternate Appreciation Rights are exercisable during such six-month period.

          4.8   Death of Optionee or Termination for Other Reasons.  Except as
provided in Section 4.7, or except as otherwise determined by the Committee, all
Alternate Appreciation Rights shall terminate upon the termination of the
Optionee's employment or upon the death of the Optionee.


                                   ARTICLE V

                                Limited Rights

          5.1   Award of Limited Rights.  Concurrently with or subsequent to the
award of any Stock Option and Alternate Appreciation Rights, the Committee may,
subject to the provisions of the Plan and such other terms and conditions as the
Committee may prescribe, award to the Optionee with respect to each Stock
Option, a related limited right permitting the Optionee, during a specified
limited time period, to be paid the appreciation on the Stock Option in lieu of
exercising the Stock Option ("Limited Right").

          5.2   Limited Rights Agreement.  Limited Rights granted under the Plan
shall be evidenced by written agreements in such form as the Committee may from
time to time determine.

          5.3   Exercise Period.  Limited Rights are immediately exercisable in
full upon grant for a period of up to seven (7) months following the date of a
Change in Control (the "Exercise Period").

          5.4   Amount of Payment.  The amount of payment to which an Optionee
shall be entitled upon the exercise of each Limited Right shall be equal to 100%
of the amount, if any, which is equal to the difference between the Option Price
of the related Stock Option and the Market Price of a share of such Common
Stock.  Market Price is defined to be the greater of:

                (a) the highest price per share of Common Stock paid, in
          connection with any Change in Control, during the period from the date
          of occurrence of a Potential Change in Control through the ninetieth
          (90th) day following the subsequent related Change in Control; and

                (b) the highest price per share of Common Stock reflected in the
          consolidated trading tables of The Wall Street Journal (presently the
          New York Stock Exchange Composite Transactions quotations) during the
          60-day period prior to the Change in Control.

          5.5   Form of Payment.  Payment of the amount to which an Optionee is
entitled upon the exercise of Limited Rights, as determined pursuant to Section
5.4, shall be made solely in cash.

          5.6   Effect of Exercise.  If Limited Rights are exercised, the Stock
Options, if any, related to such Limited Rights cease to be exercisable to the
extent of the number of shares with respect to which the Limited Rights were
exercised.  Upon the exercise or termination of the Stock

                                       11
<PAGE>

Options, if any, related to such Limited Rights, the Limited Rights granted with
respect thereto terminate to the extent of the number of shares as to which the
related Stock Options were exercised or terminated; provided, however, that with
respect to Stock Options that are terminated as a result of the termination of
the Optionee's employment status, the Limited Rights awarded in tandem therewith
shall not terminate and such Limited Rights shall remain exercisable during the
Exercise Period for any Optionee whose employment relationship with the Company
has been terminated as a result of any Qualifying Termination.

          5.7   Retirement or Disability.  Upon termination of the Optionee's
employment by reason of Disability or retirement (as each is determined by the
Committee), the Optionee may, within six (6) months from the date of
termination, exercise any Limited Rights to the extent such Limited Right is
exercisable during such six-month period.

          5.8   Death of Optionee or Termination for Other Reasons.  Except as
provided in Sections 5.7 and 5.9 or except as otherwise determined by the
Committee, all Limited Rights granted under the Plan shall terminate upon the
termination of the Optionee's employment or upon the death of the Optionee.

          5.9   Termination Related to a Change in Control. The requirement that
an Optionee be terminated by reason of retirement or permanent disability or be
employed by the Company at the time of exercise pursuant to Sections 5.7 and 5.8
respectively, is waived during the Exercise Period as to any Optionee whose
employment relationship with the Company has been terminated as a result of any
Qualifying Termination.


                                  ARTICLE VI

                            Restricted Stock Units

          6.1   Award of Restricted Stock Units.  The Committee may from time to
time, and subject to the provisions of the Plan and such other terms and
conditions as the Committee may prescribe, grant to any Participant in the Plan
rights to receive shares of Common Stock which are subject to a risk of
forfeiture by the Participant ("Restricted Stock Units").  At the time it grants
any Restricted Stock Units, the Committee shall determine whether the payment of
such Restricted Stock Units shall be conditioned solely upon the Participant's
continued employment with the Company throughout the Restriction Period or upon
the attainment of certain performance targets.

          6.2   Restricted Stock Unit Agreements. Restricted Stock Units granted
under the Plan shall be evidenced by written agreements in such form as the
Committee may from time to time determine.

          6.3   Number of Restricted Stock Units.  Upon making an award, the
Committee shall determine (and the Restricted Stock Unit Agreement shall state)
the number of Restricted Stock Units granted to the grantee.  The initial number
of Restricted Stock Units granted may be adjusted by a performance factor, in
accordance with Section 6.8, to be applied at the conclusion of the Restriction
Period to determine the final number of Restricted Stock Units to be paid.

          6.4   Length of Restriction Period.  Upon making an award, the
Committee shall determine (and the Restricted Stock Unit Agreement shall state)
the length of the Restriction Period.  Restriction Periods will normally be from
three (3) to five (5) years; however, the Committee may establish other time
periods in its sole discretion.

                                       12
<PAGE>

          6.5   Dividend Equivalents. At the Committee's discretion, each holder
of Restricted Stock Units will be entitled to receive payment from the Company
in an amount equal to each cash dividend ("Dividend Equivalent") the Company
would have paid to such holder had he or she, on the record date for payment of
such dividend, been the holder of record of shares of Common Stock equal to the
number of Restricted Stock Units which had been awarded to such holder as of the
close of business on such record date. Payment of Dividend Equivalents is
expressly conditioned on continued employment with the Company at the time of
payment. Each such payment shall be made by the Company on the payment date of
the cash dividend in respect of which it is to be made, or as soon as
practicable thereafter.

          6.6   Payment of Restricted Stock Units.

                (a) Payment in respect of Restricted Stock Units conditioned
          solely upon the Participant's continued employment with the Company
          throughout the Restriction Period shall be made within ninety (90)
          days after the Restriction Period for such Restricted Stock Units has
          ended;

                (b) Payment in respect of Restricted Stock Units conditioned
          upon the attainment of performance targets shall be made to the
          grantee thereof within ninety (90) days after the Restriction Period
          for such Restricted Stock Units has ended, but only to the extent the
          Committee determines that the applicable performance targets have been
          met and subject to any adjustment made to the number of Restricted
          Stock Units which shall be paid, pursuant to Section 6.8(b) hereof.

          6.7   Form of Payment.  Payment for Restricted Stock Units shall be
made in shares of Common Stock, except as provided in Section 6.11 hereof.  The
number of shares paid shall be equal to the number of Restricted Stock Units
earned.  The holder may elect to reduce this amount by the number of shares of
Common Stock which have, on the date the Restricted Stock Units are paid, a fair
market value equal to the applicable federal, state and local withholding tax
due on the receipt of Common Stock, in lieu of making a cash payment equal to
the amount of such withholding tax due.

          6.8   Performance Targets.

                (a) Upon the award of Restricted Stock Units, the Committee may
          establish (and the Restricted Stock Unit Agreement shall state) the
          performance targets to be attained within the Restriction Period as a
          condition of such Restricted Stock Units being earned out. Performance
          targets may be based entirely on each participant's business unit
          goals, or partially on business unit goals and partially on corporate
          goals, or entirely on corporate goals. Goals may include qualitative
          as well as quantitative measures. Performance targets may be adjusted
          during the Restriction Period, at the Committee's sole discretion, to
          reflect extraordinary events beyond management's control;

                (b) Attainment by the participant of performance targets in
          respect of a Restriction Period will result in 100% of the Restricted
          Stock Units being earned out. Attainment of performance below the
          performance targets in respect of a Restriction Period shall result in
          a proportionate amount of the value of the Restricted Stock Units (on
          a scale from 0 to 100%) being earned out, as determined by the
          Committee.

                                       13
<PAGE>

          6.9   Termination of Employment.  Except as provided in Sections 6.10
and 6.11, or except as otherwise determined by the Committee, all Restricted
Stock Units granted to a Participant under the Plan shall terminate upon
termination of the Participant's employment with the Company prior to the end of
the Restriction Period applicable to such Restricted Stock Units, and in such
event the Participant shall not be entitled to receive any payment in respect
thereof.

          6.10  Death, Disability or Retirement.  In the event that the
employment of a Participant who has been granted Restricted Stock Units under
the Plan shall terminate during a Restriction Period by reason of death,
Disability (as determined by the Committee), or retirement, such Participant
shall be entitled, in the sole discretion of the Committee, to receive upon the
expiration of the Restriction Period payment in respect of said Restricted Stock
Units; provided, however, that such Restricted Stock Units shall be adjusted by
multiplying the amount thereof by a fraction, the numerator of which shall be
the number of full and partial calendar months between the date of award of the
Restricted Stock Units and the date that employment terminated, and the
denominator of which shall be the number of full and partial calendar months
from the date of award to the end of the Restriction Period.

          6.11  Change in Control.  In the event of a Change in Control, all the
Participant's outstanding Restricted Stock Units shall be payable to the
Participant in cash or stock, as follows:

                (a) if pooling of interests accounting treatment is to be used
          with respect to such Change in Control, the Participant will receive
          shares of Common Stock equal in number to the total number of
          Restricted Stock Units granted to such Participant; or

               (b) if pooling of interests accounting treatment is not to be
          used with respect to such Change in Control, the Participant will be
          paid an amount in cash equal to the number of Restricted Stock Units
          outstanding multiplied by the Market Price as defined in Section 5.4.
          Such amount will be reduced by the applicable federal, state and local
          withholding taxes due.

          The cash or stock, as the case may be, shall be paid out to the
Participant no later than ninety (90) days following the date of occurrence of
such Change in Control (the "RSU Payout Date"), regardless of whether the
applicable Restriction Period has expired or whether performance targets have
been met.  There will be no adjustment for any performance factors described in
Section 6.8.

          On or before the RSU Payout Date, and regardless of whether pooling of
interests accounting treatment is to be used with respect to such Change in
Control, the Participant will be paid an amount in cash equal to the value of
the related accrued Dividend Equivalents immediately preceding the Change in
Control.  Payout of Restricted Stock Units and the related Dividend Equivalents
shall be made to each Participant:

               (c) who is employed by the Company on the RSU Payout Date; or

               (d) whose employment relationship with the Company is terminated:

                    (1) as a result of any Qualifying Termination prior to the
               RSU Payout Date; or

                    (2) as a result of death or Disability following the
               occurrence of any Change in Control but prior to the RSU Payout
               Date.

                                       14
<PAGE>

          The Committee may establish, at the time of the grant of Common Stock
Units, other conditions which must be met for payout to occur.  These conditions
shall be set forth in the Committee's resolution granting the Common Stock Units
and in the Agreement with the holder.


                                  ARTICLE VII

                                 Miscellaneous

          7.1   General Restriction. Each award under the Plan shall be subject
to the requirement that, if at any time the Committee shall determine that:

                (a) the listing, registration or qualification of the shares of
          Common Stock subject or related thereto upon any securities exchange
          or under any state or Federal law; or

                (b) the consent or approval of any government regulatory body,
          or

               (c) an agreement by the recipient of an award with respect to the
          disposition of shares of Common Stock,

is necessary or desirable as a condition of, or in connection with, the granting
of such award or the issue or purchase of shares of Common Stock thereunder,
such award may not be consummated in whole or in part unless such listing,
registration, qualification, consent, approval or agreement shall have been
effected or obtained free of any conditions not acceptable to the Committee.

          7.2   Accounting and Tax Treatment for Change in Control.
Notwithstanding anything in this Plan to the contrary, in the event of a Change
in Control, the Committee shall not have the right to take any actions described
in the Plan that would make the Change in Control ineligible for pooling of
interests accounting treatment or that would make the Change in Control
ineligible for desired tax treatment if, in the absence of such right, the
Change in Control would qualify for such treatment and the Company intends to
use such treatment with respect to the Change in Control.

          7.3   Non-Assignability. Awards under the Plan shall not be assignable
or transferable by the recipient thereof, except by will or by the laws of
descent and distribution. During the life of the recipient, such award shall be
exercisable only by such person or by such person's guardian or legal
representative.

          7.4   Right to Terminate Employment.  Nothing in the Plan or in any
agreement entered into pursuant to the Plan shall confer upon any Participant
the right to continue in the employment of the Company or effect any right which
the Company may have to terminate the employment of such Participant.

          7.5   Non-Uniform Determinations. The Committee's determinations under
the Plan (including without limitation, determinations of the persons to receive
awards, the form, amount and timing of such awards, the terms and provisions of
such awards, and the agreements evidencing same) need not be uniform and may be
made by it selectively among persons who receive, or are eligible to receive,
awards under the Plan, whether or not such persons are similarly situated.

                                       15
<PAGE>

          7.6   Rights as a Shareholder. The recipient of any award under the
Plan shall have no rights as a shareholder with respect thereto unless and until
certificates for shares of Common Stock are issued on behalf of such recipient.

          7.7   Leaves of Absence.  The Committee shall be entitled to make such
rules, regulations and determinations as it deems appropriate under the Plan in
respect of any leave of absence taken by the recipient of any award.  Without
limiting the generality of the foregoing, the Committee shall be entitled to
determine (i) whether or not any such leave of absence shall constitute a
termination of employment within the meaning of the Plan and (ii) the impact, if
any, of any such leave of absence on awards under the Plan theretofore made to
any recipient who takes such leaves of absence.

          7.8   Newly Eligible Employees. The Committee shall be entitled to
make such rules, regulations, determinations and awards as it deems appropriate
in respect of any employee who becomes eligible to participate in the Plan or
any portion thereof after the commencement of an award or incentive period.

          7.9   Adjustments. In any event of any change in the outstanding
Common Stock by reason of a stock dividend or distribution, recapitalization,
merger, consolidation, split-up, combination, exchange of shares or the like,
the Committee may appropriately adjust the number of shares of Common Stock
which may be issued under the Plan, the number of shares of Common Stock subject
to Stock Options theretofore granted under the Plan, the Option Price of Options
theretofore granted under the Plan, the number of Restricted Stock Units
theretofore awarded under the Plan and any and all other matters deemed
appropriate by the Committee.

          7.10  Amendment of the Plan.

                (a) The Committee may, without further action by the
          shareholders and without receiving further consideration from the
          Participants, amend this Plan or condition or modify awards under this
          Plan in response to changes in securities or other laws or rules,
          regulations or regulatory interpretations thereof applicable to this
          Plan or to comply with stock exchange rules or requirements.

                (b) The Committee may at any time, and from time to time, modify
          or amend the Plan in any respect, except that without shareholder
          approval the Committee may not:

                       (1) increase the maximum award levels established in
                Section 2.7, including the maximum number of shares of Common
                Stock which may be issued under the Plan (other than increases
                pursuant to Section 7.9);

                       (2) extend the term during which any Stock Option may be
                exercised beyond ten (10) years from the date of grant; or

                       (3) extend the term of the Plan, except that the Board
                may extend the period during which awards may be made in
                accordance with Section 2.3.

          The termination or any modification or amendment of the Plan, except
as provided in Section 7.10(a) above, shall not without the consent of a
Participant, affect the Participant's rights under an award previously granted.

                                       16

          7.11  Withholding Taxes.  Whenever the Company proposes or is required
to issue or transfer shares of Common Stock under the Plan, the Company shall
have the right to require the grantee to remit to the Company an amount
sufficient to satisfy any Federal, state and/or local withholding tax
requirements prior to the delivery of any certificate or certificates for such
shares. Whenever under the Plan payments are to be made in cash, such payments
shall be net of an amount sufficient to satisfy any Federal, state and/or local
withholding tax requirements.

                                   ARTICLE II

                 Voluntary Deferral of Directors' Compensation

     2.1  Election to Defer.  Prior to the beginning of any calendar quarter, a
Participant may elect to defer all or a portion of the Compensation that would
otherwise be paid to the Participant in the next succeeding calendar quarter, by
filing a written notice of election with the Committee on the form(s) prescribed
by the Committee. Any such deferral election shall apply only to Compensation to
be earned on or after the first day of the calendar quarter following the
calendar quarter in which the election is received by the Committee. An election
to defer, made in accordance with this Article II shall be irrevocable. The
deferral election form(s) also will permit the Participant to specify:

          (a)  the percentage of Compensation to be deferred;

          (b)  the form of deferral, being either Cash Units, Share Units, or a
     combination of the two and the percentage allocations of such;

          (c)  the selection of a method of payment as set forth in Article III;
     and

          (d)  the designation of a beneficiary as set forth in Article V.

     Without any further action by Participant, the choices specified in the
Participant's Deferred Payment Election Form regarding the percentage of
Compensation deferred, the form of deferral, the designation of a beneficiary,
and the method of payment shall each continue and be applied from calendar
quarter to calendar quarter to amounts yet to be deferred. Until further express
written notification, on a form prescribed by the Committee, to the contrary,
these choices shall continue to be applied to amounts to be credited to such
Deferred Compensation Account balance prospectively.

     2.2  Subsequent Change in Method of Payment Election.

          (a)  Change in Method of Payment Prior to Commencement of Distribution
     or Payment. With the approval of the Committee, and at any time not later
     than twelve (12) months prior to the commencement of any payment or
     distribution of the amounts credited to the Participant's Deferred
     Compensation Account, a Participant in this portion of the Plan may file a
     written request with regard to the method of payment (i.e., a series of
     installments versus lump-sum payout), on a form prescribed by the
     Committee, which will revoke all such earlier or prior elections with
     regard to the method of payment (i.e., a series of installments versus
     lump-sum payout), and such new choice as to method of payment will be
     applied both to amounts previously credited to the Participant's current
     Deferred Compensation Account balance, as well as to amounts to be credited
     to such Deferred Compensation Account balance prospectively. Any such new
     or subsequent election that is made less than twelve (12) months prior to
     the commencement of any payment or distribution of the amounts credited to
     the Participant's Deferred Compensation Account, will be null and void, and
     the Participant's next preceding timely election will be reinstated.

          (b)  Change in Method of Payment Following Commencement of
     Distribution or Payment. After payment or distribution of amounts credited
     to the Participant's Deferred

                                       3
<PAGE>

     Compensation Account has commenced, the Participant may not change the
     period of time for which such amounts are payable. However the Participant
     may convert installment payments to a lump sum distribution subject to a
     penalty equal to a five percent (5%) reduction in the balance of the
     Participant's Deferred Compensation Account, which shall be forfeited to
     the Company.

     2.3  Amount of Deferral  The amount of Compensation to be deferred shall be
designated by the Participant as a percentage of the Director's Compensation in
multiples of five percent (5%) but shall not be less than ten percent (10%).

     2.4  Time of Election  Except as otherwise determined by the Committee in
its sole discretion, an election to defer must be filed and received by the
Committee by the end of the calendar quarter preceding the calendar quarter in
which the Compensation is to be earned. A new Director may also elect to defer
Compensation prior to the commencement of his or her term in office.

                                  ARTICLE III

                    Voluntary Deferred Compensation Accounts

     3.1  Creation of Voluntary Deferred Compensation Accounts.  Compensation
deferred hereunder shall be credited to a Deferred Compensation Account
established by the Company for each Participant. The Participant must elect to
convert the deferred compensation to either Cash Units or Share Units, which
shall be credited to a Participant's Deferred Compensation Account as set forth
in the Plan.

     3.2 Crediting Share Units.  Share Units shall be credited to a
Participant's Deferred Compensation Account at the time the Compensation would
otherwise have been paid had no election to defer been made. The number of Share
Units to be credited to the Deferred Compensation Account shall be determined by
dividing the Compensation by the average closing price for Shares as published
in the Wall Street Journal under the caption "New York Stock Exchange Composite
Transactions" for the ten (10) day period prior to the day on which the
Compensation would otherwise have been paid. Any fractional Share Units shall
also be credited to a Participant's Deferred Compensation Account. The number of
Share Units in a Deferred Compensation Account shall be appropriately adjusted
by the Committee in the event of changes in the Company's outstanding common
stock by reason of a stock dividend or distribution, recapitalization, merger,
consolidation, split-up, combination, exchange of shares or the like, and such
adjustments shall be conclusive. Share Units shall not entitle any person to the
rights of a stockholder.

     3.3  Crediting Cash Units.  Cash Units shall be credited to a Participant's
Deferred Compensation Account at the time Compensation would otherwise have been
paid had no election to defer been made.

     3.4  Crediting Dividend Equivalents.  For Share Units, the Company shall
credit the Participant's Deferred Compensation Account with Dividend Equivalents
being equal to the dividends declared on the Company's Shares. The crediting
shall occur as of the date on which said dividends are paid. The number of Share
Units to be credited to the Deferred Compensation Account shall be calculated by
dividing the Dividend Equivalents by the average closing price for

                                       4
<PAGE>

Shares as published in the Wall Street Journal under the caption "New York Stock
Exchange Composite Transactions" for the period of ten (10) trading days prior
to the day on which the dividends are paid on the Company's Shares. Any
fractional Share Units shall also be credited to a Participant's Deferred
Compensation Account.

     3.5 Crediting Interest Equivalents.  For Cash Units credited to their
Deferred Compensation Accounts, the Company shall credit the Participant's
Deferred Compensation Account on a quarterly basis with an Interest Equivalent.

     3.6 Share Unit Conversion.  Immediately upon termination of Board service,
and so prior to the commencement of any payout or distribution of any amounts
hereunder, a Participant may make a one-time election to convert to Cash Units
all or a portion of the balance of Share Units in such Participant's Deferred
Compensation Account. Any Share Units so converted to Cash Units as a result of
this one-time conversion election shall be valued at the average closing price
for Shares as published in the Wall Street Journal under the caption "New York
Stock Exchange Composite Transactions" for the ten (10) day period immediately
prior to such one-time conversion election.

     3.7  Time of Payment.

          (a)  Election of Benefit Commencement Date. Except as provided in
     Section 2.2 hereinabove, and in Article VII hereof, all payments of a
     Participant's Deferred Compensation Account shall be made at, or shall
     commence on, the date selected by the Participant in accordance with the
     terms of this Section 3.7. The date of payment or distribution must be
     irrevocably specified by the Participant in his or her most recently filed
     written Deferred Payment Election Form. If the Participant fails to
     designate a time of payment, payment shall commence on the first day of the
     calendar year following termination of Board membership. The Participant
     may elect to defer the receipt of his or her Compensation to:

               (1)  the first day of any calendar quarter, provided such date is
          at least six (6) months after the end of the calendar quarter in which
          the Compensation is earned; or

               (2)  the first day of the calendar year following the date of:

                    (i)   retirement as a Director;

                    (ii)  termination of Board membership; or

                    (iii) death. Upon the death of a Director or former
                          Director, prior to the final payment of all amounts
                          credited to his or her Deferred Compensation Account,
                          the balance of the Deferred Compensation Account shall
                          be paid in accordance with Article V, commencing on
                          the first day of the calendar year following the year
                          of death.

     Notwithstanding the foregoing provisions of this Section 3.7, and except as
provided in Article VII, in no event shall any payment or distribution be made
within six (6) months of the Compensation being earned or awarded. The benefit
commencement date may not be later than the third calendar year following the
attainment of mandatory retirement age for Directors.

                                       5
<PAGE>

          (b)  Acceleration of Benefit Commencement Date Prior to Payment. At
     any time prior to the commencement of any payment or distribution of a
     Participant's Deferred Compensation Account, such Participant may request
     in writing to accelerate the receipt of all or a specified portion of such
     deferred Compensation amounts to the first day of any calendar quarter;
     provided, however, that such date is at least six (6) months after the end
     of the quarter in which the Compensation is earned. Any such acceleration
     will be subject to a penalty equal to a five percent (5%) reduction in the
     balance of the Participant's Deferred Compensation Account, which shall be
     forfeited to the Company;

     3.8  Method of Payment.  A Participant in this portion of the Plan shall
have the option of:

          (a)  selecting a lump-sum payment;

          (b)  selecting a series of approximately equivalent annual
     installments (adjusted as necessary to reflect Dividend Equivalents and/or
     Interest Equivalents accrued during the installment payout period) in such
     number of installments as the Participant shall specify (not exceeding ten
     (10) installments); or

          (c)  not selecting a method of payment at the time the Deferred
     Payment Election Form is prepared. If the Participant does not select a
     method of payment, he or she must, at least twelve (12) months prior to the
     time the deferral amount is scheduled to be paid, notify the Corporate
     Secretary as to the specific method of payment which will be either in a
     lump sum or in approximately equivalent annual installments, and such
     election shall be subject to the consent of the Committee. Failure to
     provide appropriate notification to the Corporate Secretary will result in
     a lump sum payment on the deferral payment date.

     Participant shall receive in cash all deferred compensation credited to
such Participant's Deferred Compensation Account. Share Units credited to the
Participant's Deferred Compensation Account shall be valued at the average
closing price for Shares as published in the Wall Street Journal under the
caption "New York Stock Exchange Composite Transactions" for the ten (10) day
period prior to each new calendar year.

                                   ARTICLE IV

                   Restricted Deferred Compensation Accounts

     4.1  Creation of Restricted Deferred Compensation Accounts.  Compensation
deferred under this Article IV shall be credited to a Restricted Deferred
Compensation Account established by the Company for each Participant. The
Restricted Deferred Compensation Accounts will be initialized as of February 15,
1996 by transferring to the Plan the present value of the accrued benefits of
each Participant in the Non-Employee Directors' Retirement Plan. The present
value of these accrued benefits will then be converted into Restricted Share
Units. The number of Restricted Share Units to be credited to the Restricted
Deferred Compensation Account of each Participant will be determined by using
the average closing price for Shares as published in the Wall Street Journal
under the caption "New York Stock Exchange Composite Transactions" for the ten
(10) business days prior to February 15, 1996. Payout of these Restricted Share
Units shall not commence until death, retirement or the termination of Board
service.

                                       6
<PAGE>

     4.2  Crediting Share Units.  If the Committee elects to do so, each year in
conjunction with either the Participant's election or re-election to the Board,
a yearly dollar amount ("Yearly Credit") will be credited to a Participant's
Restricted Deferred Compensation Account in the form of Restricted Share Units.
The number of Restricted Share Units credited to a Participant's Restricted
Deferred Compensation Account shall be determined by dividing the Yearly Credit
by the average closing price for Shares as published in the Wall Street Journal
under the caption "New York Stock Exchange Composite Transactions" ten (10) day
period prior to the Company's annual meeting. Any fractional Restricted Share
Units shall also be credited to a Participant's Restricted Deferred Compensation
Account. The number of Restricted Share Units in a Restricted Deferred
Compensation Account shall be appropriately adjusted by the Committee in the
event of changes in the Company's outstanding common stock by reason of a stock
dividend or distribution, recapitalization, merger, consolidation, split-up,
combination, exchange of shares or the like, and such adjustments shall be
conclusive. Restricted Share Units shall not entitle any person to the rights of
a stockholder.

     4.3 Crediting Dividend Equivalents.  The Company shall credit the
Participant's Restricted Deferred Compensation Account with Dividend Equivalents
being equal to the dividends declared on the Company's Shares. The crediting
shall occur as of the date on which said dividends are paid. The number of
Restricted Share Units to be credited to the Restricted Deferred Compensation
Account shall be calculated by dividing the Dividend Equivalents by the average
closing price for Shares as published in the Wall Street Journal under the
caption "New York Stock Exchange Composite Transactions" for the period of ten
(10) trading days prior to the day on which the dividends are paid on the
Company's Shares. Any fractional Restricted Share Units shall also be credited
to a Participant's Restricted Deferred Compensation Account.

     4.4  Restricted Share Unit Conversion.  Immediately upon termination of
Board service, and so prior to the commencement of any payout or distribution of
any amounts hereunder, a Participant may make a one-time election to convert to
Cash Units all or a portion of the balance of Restricted Share Units in such
Participant's Restricted Deferred Compensation Account. Any Restricted Share
Units so converted to Cash Units as a result of this one-time conversion
election shall be valued at the average closing price for Shares as published
in the Wall Street Journal under the caption "New York Stock Exchange Composite
Transactions" for the ten (10) day period immediately prior to such one-time
conversion election.

     4.5  Time of Payment.

          (a)  Benefit Commencement Date for Restricted Deferred Compensation
     Account. All payments of a Participant's Restricted Deferred Compensation
     Account shall be made at, or shall commence on, the date selected by the
     Participant in accordance with the terms of this Article IV. The date of
     payment or distribution must be specified by the Director in his or her
     written Form of Continuing Deferral unless such election is revoked. A
     Participant's revocation must be submitted to the Corporate Secretary in
     writing. If the Participant selects a new election with regard to the date
     of payment or distribution, such election will apply only prospectively to
     any additional Restricted Share Units to be credited to a Director's
     Restricted Deferred Compensation Account. If the Participant fails to
     designate a time of payment, payment shall commence on the first day of the
     calendar year following termination of Board service. The Participant may
     elect to defer the receipt of his or her Compensation to the first day of
     the year following the date of:

               (a)  retirement as a Director;

                                       7
<PAGE>

               (b)  termination of Board service; or

               (c)  death.  Upon the death of a Director or former Director,
               prior to the final payment of all amounts credited to his or her
               Account, the balance of the Restricted Deferred Compensation
               Account shall be paid in accordance with Article V, commencing on
               the first day of the calendar year following the year of death.

          Notwithstanding the foregoing provisions of this Section 4.5, in no
     event, however, shall any payment or distribution be made within the six
     (6) months of the Compensation being earned. The benefit commencement date
     may not be later than the third calendar year following the attainment of
     mandatory retirement age for Participants.

          (b)  Acceleration of Benefit Commencement Date Prior to Payment. At
     any time prior to the commencement of any payment or distribution of a
     Participant's Restricted Deferred Compensation Account, such Participant
     may request in writing to accelerate the receipt of all or a specified
     portion of such Restricted Deferred Compensation Account amounts to the
     first day of any calendar quarter; provided, however, that such date is at
     least six (6) months after the end of the quarter in which the Compensation
     is earned. Any such acceleration will be subject to a penalty equal to a
     five percent (5%) reduction in the balance of the Participant's Restricted
     Deferred Compensation Account, which shall be forfeited to the Company.

     4.6  Method of Payment.  Participant shall have the option of:

          (a)  selecting a lump sum payment;

          (b)  selecting a series of approximately equivalent annual
     installments (adjusted as necessary to reflect Dividend Equivalents and/or
     Interest Equivalents accrued during the installment payout period) in such
     number of installments as the Participant shall specify (not exceeding ten
     (10) installments); or

          (c)  not selecting a method of payment at the time the Form for
     Continuing Deferral is prepared. If the Participant does not select a
     method of payment, he or she must, at least twelve months prior to the time
     the deferral amount is scheduled to be paid, notify the Corporate Secretary
     as to the specific method of payment which will be either in a lump sum or
     in approximately equivalent annual installments, and such election shall be
     subject to the consent of the Committee. Failure to provide appropriate
     notification to the Corporate Secretary will result in a lump sum payment
     on the deferral payment date.

          Share Units credited to the Participant's Restricted Deferred
     Compensation Account shall be valued at the average closing price for
     Shares as published in the Wall Street Journal under the caption "New York
     Stock Exchange Composite Transactions" for the ten (10) day period prior to
     each new calendar year.

     4.7  Subsequent Change in Method of Payment Election.

          (a)  Change in Method of Payment Prior to Commencement of Distribution
     or Payment. With the approval of the Committee, and at any time not later
     than twelve (12) months

                                       8
<PAGE>

     prior to the commencement of any payment or distribution of the amounts
     credited to the Participant's Restricted Deferred Compensation Account, a
     Participant in this portion of the Plan may file a written request with
     regard to the method of payment (i.e., a series of installments versus
     lump-sum payout), on a form prescribed by the Committee, which will revoke
     all such earlier or prior elections with regard to the method of payment
     (i.e., a series of installments versus lump-sum payout), and such new
     choice as to method of payment will be applied both to amounts previously
     credited to the Participant's current Restricted Deferred Compensation
     Account balance, as well as to amounts to be credited to such Restricted
     Deferred Compensation Account balance prospectively. Any such new or
     subsequent election that is made less than twelve (12) months prior to the
     commencement of any payment or distribution of the amounts credited to the
     Participant's Restricted Deferred Compensation Account, will be null and
     void, and the Participant's next preceding timely election will be
     reinstated.

          (b)  Change in Method of Payment Following Commencement of
     Distribution or Payment. After payment or distribution of amounts credited
     to the Participant's Restricted Deferred Compensation Account has
     commenced, the Participant may not change the period of time for which such
     amounts are payable. However the Participant may convert installment
     payments to a lump sum distribution subject to a penalty equal to a five
     percent (5%) reduction in the balance of the Participant's Restricted
     Deferred Compensation Account, which shall be forfeited to the Company.

                                   ARTICLE V

                          Designation of Beneficiaries

     5.1  Designation of Beneficiary.  The Participant shall name one or more
beneficiaries and contingent beneficiaries to receive any payments due
Participant at the time of death. No designation of beneficiaries shall be valid
unless in writing signed by the Participant, dated and filed with the Committee
during the lifetime of such Participant. A subsequent beneficiary designation
will cancel all beneficiary designations signed and filed earlier under this
Plan, and such new beneficiary designation shall be applied to all amounts
previously credited to the Participant's Deferred Compensation Account (or
Restricted Deferred Compensation Account, as the case may be), as well as to any
amounts to be credited to such Participant's Deferred Compensation Account (or
Restricted Deferred Compensation Account, as the case may be), prospectively. In
case of a failure of designation, or the death of the designated beneficiary
without a designated successor, distribution shall be paid in one lump sum to
the estate of the Participant.

     5.2  Spouse's Interest.  The interest in any amounts hereunder of a spouse
who has predeceased the Participant shall automatically pass to the Participant
and shall not be transferable by such spouse in any manner, including but not
limited to such spouse's will, nor shall such interest pass under the laws of
intestate succession.

     5.3  Survivor Benefits.  Upon the Participant's death, any balances in the
Participant's Deferred Compensation Account and Restricted Deferred Compensation
Account shall be paid in accordance with the method and form elected by the
Participant; provided, however, that the balance of the Participant's Deferred
Compensation Account and Restricted Deferred

                                       9
<PAGE>

Compensation Account may be paid out as a lump sum at the request of the
designated beneficiary, and with the consent of the Committee.

                                   ARTICLE VI

                               Source of Payments

     All payments of deferred compensation shall be paid in cash from the
general funds of the Company and the Company shall be under no obligation to
segregate any assets in connection with the maintenance of a Deferred
Compensation Account or Restricted Deferred Compensation Account, nor shall
anything contained in this Plan nor any action taken pursuant to the Plan create
or be construed to create a trust of any kind, or a fiduciary relationship
between the Company and Participant. Title to the beneficial ownership of any
assets, whether cash or investments, which the Company may designate to pay the
amount credited to the Deferred Compensation Account or a Restricted Deferred
Compensation Account shall at all times remain in the Company and Participant
shall not have any property interest whatsoever in any specific assets of the
Company. Participant's interest in the Deferred Compensation Account or a
Restricted Deferred Compensation Account shall be limited to the right to
receive payments pursuant to the terms of this Plan and such rights to receive
shall be no greater than the right of any other unsecured general creditor of
the Company.

                                  ARTICLE VII

                               Change in Control

     7.1  Acceleration of Payment Upon Change in Control.  The terms of this
Section 7.1 shall immediately become operative, without further action or
consent by any person or entity, upon a Change in Control, and once operative
shall supersede and control over any other provisions of this Plan.  Upon the
occurrence of a Change in Control, and for twelve (12) months thereafter, each
Participant, whether or not he or she is still a Director, shall have the right
to withdraw, in a single lump-sum cash payment, an amount equal to ninety-five
percent (95%) of the balance of each of his or her Deferred Compensation Account
and Restricted Deferred Compensation Account, as of the valuation date
immediately preceding the date of  withdrawal; provided, however, that if this
option is exercised, such Participant will forfeit to the Company the remaining
five percent (5%) of the balance of each such account (as of the valuation date
immediately preceding the date of withdrawal) from which the funds are withdrawn
as a penalty. Payments under this Section 7.1 shall be made as soon as
practicable, but no later than thirty (30) days after the Participant notifies
the Committee in writing that he/she is exercising his/her right to withdraw
pursuant to this Section 7.1.

     7.2  Amendment on or after Change in Control.  On or after a Change in
Control, no action, including by way of example and not of limitation, the
amendment, suspension or termination of the Plan, shall be taken which would
affect the rights of any Participant or the operation of this Plan with respect
to the balance in the Participant's Accounts.

     7.3  Attorney's Fees.  The Company shall pay all legal fees and related
expenses incurred by a Participant in seeking to obtain or enforce any payment,
benefit or right such Participant may be entitled to under the plan after a
Change in Control. The Participant shall reimburse the Company

                                      10
<PAGE>

for such fees and expenses at such time as a court of competent jurisdiction, or
another independent third party having similar authority, determines that the
Participant's claim was frivolously brought without reasonable expectation of
success on the merits thereof.

                                  ARTICLE VIII

                           Nonalienation of Benefits

     Participant shall not have the right to sell, assign, transfer or otherwise
convey or encumber in whole or in part the right to receive any payment under
this Plan except in accordance with Article V.

                                   ARTICLE IX

                              Acceptance of Terms

     The terms and conditions of this Plan shall be binding upon the heirs,
beneficiaries and other successors in interest of Participant to the same extent
that said terms and conditions are binding upon the Participant.

                                   ARTICLE X

                           Administration of the Plan

     The Plan shall be administered by the Committee which may make such rules
and regulations and establish such procedures for the administration of this
Plan as it deems appropriate. In the event of any dispute or disagreements as to
the interpretation of this Plan or of any rule, regulation or procedure or as to
any questioned right or obligation arising from or related to this Plan, the
decision of the Committee shall be final and binding upon all persons.

                                   ARTICLE XI

                           Termination and Amendment

     The Plan may be terminated at any time by the Board of Directors of Sunoco,
Inc. and may be amended at any time by the Committee provided, however, that no
such amendment or termination shall adversely affect the rights of Participants
or their beneficiaries with respect to amounts credited to Deferred Compensation
Accounts or Restricted Deferred Compensation Accounts prior to such amendment or
termination, without the written consent of the Participant.

                                  ARTICLE XII

                                  Construction

     In the case any one or more of the provisions contained in this Plan shall
be invalid, illegal or unenforceable in any respect the remaining provisions
shall be construed in order to effectuate

                                      11
<PAGE>

the purposes hereof and the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

                                 Governing Law

     This Plan shall be construed in accordance with and governed by the laws of
the Commonwealth of Pennsylvania.

                                   ARTICLE II

                         Background and Purpose of Plan

     2.1  Purpose.  The Company has established this Deferred Compensation Plan
to provide Executive Resource Employees who are participants in the Incentive
Plan with the option to irrevocably defer the receipt of all or a portion of the
bonus to which such participants would otherwise be entitled, subject to the
terms and conditions hereinafter set forth.

     2.2  Creation of Deferred Bonus Account.  Each of the following shall
be credited to a Deferred Bonus Account established by the Company for each
Participant:

          (a)  any bonus amounts voluntarily deferred by the Participant
     pursuant to Article III (Deferral of Bonuses by Participant) hereof; and/or

          (b)  any Non-Cash Bonus amounts deferred in the discretion of the
     Committee pursuant to Article IV (Deferral of Bonuses by Committee) hereof.

     Any bonus amounts voluntarily deferred by the Participant will be
credited to a Participant's Deferred Bonus Account in the form of Cash Units or
Share Units, in the discretion of the Participant, as set forth in the Plan.
The deferral of any Non-Cash Bonus amounts caused by action of the Committee
will be credited to a Participant's Deferred Bonus Account in the form of Cash
Units or Share Units as the Committee, in its sole discretion, may decide in
accordance with the Plan.

                                  ARTICLE III

                       Deferral of Bonuses by Participant

     3.1  Participant's Election to Defer.  A Participant voluntarily may
elect to defer, in the form of Cash Units or Share Units, all or a portion of
his or her bonus to be awarded under the Incentive Plan by filing a written
election with the Committee on forms prescribed by the Committee. Such election
must include the following:

          (a)  percentage of bonus to be deferred;

          (b)  the form of deferral, being either Cash Units, Share Units or a
     combination of the two and the percentage allocations of such;

          (c)  a designation of beneficiary as set forth in Article VI
     (Designation of Beneficiaries); and

          (d)  an irrevocable election of a method of payment as set forth in
     Section 3.10 hereof.

                                       4
<PAGE>

     Any such voluntary election by the Participant shall apply only to bonuses
for the year specified in the election.

     3.2  Amount of Deferral  The amount of bonus to be deferred in any year
shall be designated by the Participant as a percentage of such Participant's
bonus in multiples of five percent (5%) but shall not be less than ten percent
(10%).

     3.3  Time of Election.  A separate election to defer must be filed for
each year and must be received by the Company no later than forty-five (45) days
before the end of the year in which the bonus is earned. Any election by a
Participant with respect to a bonus in a given year will not preclude a
different action with respect to bonuses in subsequent years, consistent with
the provisions of this Article III with respect to the giving of notice of
deferral election.

     3.4  Crediting Share Units.  Share Units shall be credited to a
Participant's Deferred Bonus Account at the time the bonus otherwise would have
been paid had no election to defer been made. The number of Share Units to be
credited to the Deferred Bonus Account shall be determined by dividing the
portion of bonus to be deferred by the average closing price for Shares as
reported on the New York Stock Exchange-Composite Transactions for the ten (10)
day period prior to the day on which the bonus otherwise would have been paid.
Any fractional Share Units shall also be credited to a Participant's Deferred
Bonus Account. Share Units shall not entitle any person to the rights of a
shareholder.

     3.5  Crediting Dividend Equivalents.  For Share Units, the Company
shall credit the Participant's Deferred Bonus Account with Dividend Equivalents
being equal to the dividends declared on the Company's Shares. The crediting
shall occur as of the date on which said dividends are paid. The number of Share
Units to be credited to the Deferred Bonus Account shall be calculated by
dividing the Dividend Equivalents by the average closing price for Shares as
reported on the New York Stock Exchange-Composite Transactions for the period of
ten (10) trading days prior to the day on which the dividends are paid on the
Company's Shares. Any fractional Share Units shall also be credited to a
Participant's Deferred Bonus Account.

     3.6  Crediting Cash Units.  Cash Units shall be credited to a
Participant's Deferred Bonus Account at the time the bonus would otherwise have
been paid had no election to defer been made.

     3.7  Crediting Interest Equivalents.  For Cash Units credited to a
Participant's Deferred Bonus Account, the Company shall credit such
Participant's Deferred Bonus Account on a quarterly basis with an Interest
Equivalent.

     3.8  Share Unit Conversion.  Immediately upon termination of the
Participant's employment with the Company, and so prior to the commencement of
any payout or distribution of any amounts hereunder, the Participant may make a
one-time election to convert to Cash Units all or a portion of the balance of
Share Units in such Participant's Deferred Bonus Account. Any Share Units so
converted to Cash Units as a result of this one-time conversion election shall
be valued at the average closing price for Shares as reported on the New York
Stock Exchange - Composite Transactions for the ten (10) day period immediately
prior to such one-time conversion election.

     3.9  Time of Payment.  Except as provided in Article V ("Change in
Control") hereof, all payments of a Participant's Deferred Bonus Account shall
be made at, or shall commence on, the date selected by the Participant in
accordance with the terms of this Article III.

          (a)  Election of Benefit Commencement Date.  The date of payment or
     distribution must be irrevocably specified by the Participant in his or her
     written notice of election.  The Participant may elect to defer the receipt
     of all or a specified portion of such Participant's bonus to:

               (1)  the first day of any calendar year provided such date is
          at least six (6) months after the end of the quarter in which the
          bonus is earned; or

               (2)  the first day of the calendar year following the date of:

                    (i)   the Participant's retirement;

                    (ii)  final determination that the Participant has a
                          Permanent and Total Disability;

                    (iii) termination of the Participant's employment with the
                          Company;

                    (iv)  death of the Participant. Upon the death of a
                          Participant prior to the final payment of all amounts
                          credited to his or her Deferred Bonus Account, the
                          balance of the Deferred Bonus Account shall be paid in
                          accordance with Article VI ("Designation of
                          Beneficiaries") hereof, commencing on the first day of
                          the calendar year following the year of death.

     Notwithstanding the foregoing provisions of this Section 3.9, and except as
provided in Article V ("Change in Control") hereof, in no event shall any
payment or distribution be made within six (6) months of the bonus being earned
or awarded. The benefit commencement date may not be later than the third
calendar year following the date of: (i) Participant's retirement, or (ii)
termination of Participant's employment.

          (b)  Acceleration of Benefit Commencement Date Prior to Payment.  At
     any time prior to the commencement of any payment or distribution of a
     Participant's Deferred Bonus Account, such Participant may request in
     writing to accelerate the receipt of all or a specified portion of such
     deferred bonus amounts to the first day of any calendar year; provided,
     however, that such date is at least six (6) months after the end of the
     quarter in which the bonus is earned. Any such acceleration will be subject
     to a penalty equal to a five percent (5%) reduction in the balance of the
     Participant's Deferred Bonus Account, which shall be forfeited to the
     Company.

     3.10 Method of Payment.  A Participant in this portion of the Deferred
Compensation Plan shall have the option of:

          (a)  selecting a lump-sum payment;

                                       6
<PAGE>

          (b)  selecting a series of approximately equivalent annual
     installments (adjusted as necessary to reflect Dividend Equivalents and/or
     Interest Equivalents accrued during the installment payout period) in such
     number of installments as the Participant shall specify (not exceeding ten
     (10) installments); or

          (c)  not selecting a method of payment at the time the Form for
     Deferred Payment Election/Designation of Beneficiary is prepared. If the
     Participant does not select a method of payment, he or she must, at least
     twelve (12) months prior to the time the deferral amount is scheduled to be
     paid, notify the Company as to the specific method of payment which will be
     either in a lump sum or in approximately equivalent annual installments.
     Failure to provide appropriate notification to the Company will result in a
     lump sum payment on the deferral payment date.

     Participant shall receive in cash all deferred compensation credited to
such Participant's Deferred Compensation Account. Share Units credited to the
Participant's Deferred Compensation Account shall be valued at the average
closing price for Shares as reported on the New York Stock Exchange-Composite
Transactions for the ten (10) day period prior to each new calendar year.

     3.11 Subsequent Change in Method of Payment Election.

          (a)  Change in Method of Payment Prior to Commencement of Distribution
     or Payment. With the approval of the Committee, and at any time not later
     than twelve (12) months prior to the commencement of any payment or
     distribution of the amounts credited to the Participant's Deferred Bonus
     Account, a Participant in this portion of the Plan may file a written
     request with regard to the method of payment (i.e., a series of
     installments versus lump-sum payout), on a form prescribed by the
     Committee, which will revoke all such earlier or prior elections with
     regard to the method of payment (i.e., a series of installments versus
     lump-sum payout), and such new choice as to method of payment will be
     applied both to amounts previously credited to the Participant's current
     Deferred Bonus Account balance, as well as to amounts to be credited to
     such Deferred Bonus Account balance prospectively. Any such new or
     subsequent election that is made less than twelve (12) months prior to the
     commencement of any payment or distribution of the amounts credited to the
     Participant's Deferred Bonus Account, will be null and void, and the
     Participant's next preceding timely election will be reinstated.

          (b)  Change in Method of Payment Following Commencement of
     Distribution or Payment. After payment or distribution of amounts credited
     to the Participant's Deferred Bonus Account has commenced, the Participant
     may not change the period of time for which such amounts are payable.
     However the Participant may convert installment payments to a lump sum
     distribution subject to a penalty equal to a five percent (5%) reduction in
     the balance of the Participant's Deferred Bonus Account, which shall be
     forfeited to the Company.

     3.12 Hardship Distribution.  Participant may request a modification in the
payment terms hereunder only in the event of severe financial hardship and only
to the extent reasonably necessary to eliminate the hardship. Such request shall
specify in detail the grounds for the requested modification and shall be
referred to the Committee. A qualifying severe financial

                                       7
<PAGE>

hardship must be caused by accident, illness, or event beyond the control of the
Participant. The decision of the Committee with respect to the requested
modification shall be solely at the discretion of the Committee and in
accordance with its evaluation of the exigencies of the situation. Such decision
shall be binding on the Company and Participant.

                                   ARTICLE IV

                        Deferral of Bonuses by Committee

     4.1  Committee's Election to Defer.  Each year in conjunction with the
award of any bonus to the Participant, the Committee, in its sole discretion,
may cause to be credited to a Participant's Deferred Bonus Account in the form
of either Cash Units or Share Units, a specified dollar amount representing all
or a portion of such Participant's bonus for that year (the "Non-Cash Bonus").

     4.2  Crediting Share Units.  Share Units shall be credited to a
Participant's Deferred Bonus Account at the time the bonus would otherwise have
been paid had no Committee action to defer been taken. The number of Share Units
credited to the Participant's Deferred Bonus Account shall be determined by
dividing the Non-Cash Bonus by the average closing price for Shares as reported
on the New York Stock Exchange-Composite Transactions for the ten (10) day
period prior to the date such bonus otherwise would have been paid had no
Committee action been taken. Any fractional Share Units shall also be credited
to such Participant's Deferred Bonus Account. Share Units shall not entitle any
person to the rights of a stockholder.

     4.3  Crediting Dividend Equivalents.  The Company shall credit the
Participant's Deferred Bonus Account with Dividend Equivalents being equal to
the dividends declared on the Company's Shares. The crediting shall occur as of
the date on which said dividends are paid. The number of Share Units to be
credited to the Deferred Bonus Account shall be calculated by dividing the
Dividend Equivalents by the average closing price for Shares as reported on the
New York Stock Exchange-Composite Transactions for the period of ten (10)
trading days prior to the day on which the dividends are paid on the Company's
Shares. Any fractional Share Units shall also be credited to a Participant's
Deferred Bonus Account.

     4.4  Crediting Cash Units.  Cash Units shall be credited to a Participant's
Deferred Bonus Account at the time the bonus otherwise would have been paid had
no Committee action to defer been taken.

     4.5  Crediting Interest Equivalents.  For Cash Units credited to a
Participant's Deferred Bonus Account, the Company shall credit such
Participant's Deferred Bonus Account on a quarterly basis with an Interest
Equivalent.

     4.6  Share Unit Conversion.  Immediately upon termination of the
Participant's employment with the Company, and so prior to the commencement of
any payout or distribution of any amounts hereunder, the Participant may make a
one-time election to convert to Cash Units all or a portion of the balance of
Share Units in such Participant's Deferred Bonus Account.  Any Share Units so
converted to Cash Units as a result of this one-time conversion election shall
be valued at the average closing price for Shares as reported on the New York
Stock Exchange - Composite Transactions for the ten (10) day period immediately
prior to such one-time conversion election.

                                       8
<PAGE>

     4.7  Time of Payment.

          (a)  Benefit Commencement Date Specified by Committee.  The Committee
     will specify in writing its election of the earliest date of payment or
     distribution, and such election shall remain effective until revoked in
     writing by the Committee. If the Committee elects a new date with regard to
     payment or distribution, such election will apply only prospectively to any
     additional Share Units and/or Cash Units to be credited to such
     Participant's Deferred Bonus Account by Committee action in accordance with
     this Article IV. If the Committee fails to designate a time of payment,
     payment shall commence on the first day of the calendar year following the
     termination of such Participant's employment. Notwithstanding the foregoing
     provisions of this Section 4.7, in no event, however, shall the payment
     date be later than the third calendar year following the date of: (i)
     Participant's retirement, or (ii) termination of Participant's employment.

          (b)  Acceleration of Benefit Commencement Date Prior to Payment.  At
     any time prior to the commencement of any payment or distribution of a
     Participant's Deferred Bonus Account, such Participant may request in
     writing to accelerate the receipt of all or a specified portion of such
     deferred bonus amounts to the first day of any calendar year; provided,
     however, that such date is at least six (6) months after the end of the
     quarter in which the bonus is earned. Any such acceleration will be subject
     to a penalty equal to a five percent (5%) reduction in the balance of the
     Participant's Deferred Bonus Account, which shall be forfeited to the
     Company.

     4.8  Method of Payment.  The Participant must select a method of payment at
least twelve (12) months prior to the time the deferral amount is scheduled to
be paid, by notifying the Company as to whether the method of payment will be
either:

          (a)  a lump sum payment; or

          (b)  a series of approximately equivalent annual installments
     (adjusted as necessary to reflect Dividend Equivalents accrued during the
     installment payout period), in such number of installments as the
     Participant shall specify (not exceeding ten (10) installments).

     If no election is made, payment or distribution of any amounts deferred by
Committee action pursuant to this Article IV (together with the Dividend
Equivalents and/or Interest Equivalents, as the case may be, accrued thereon)
shall be made in a single lump sum on the earliest payment date permitted by the
Committee as provided under Section 4.7 hereof. Share Units credited to the
Participant's Deferred Bonus Account shall be valued at the average closing
price for Shares as reported on the New York Stock Exchange-Composite
Transactions for the ten (10) day period prior to each new calendar year.

     4.9  Subsequent Change in Method of Payment Election.

          (a)  Change in Method of Payment Prior to Commencement of Distribution
     or Payment.  With the approval of the Committee, and at any time not later
     than twelve (12)

                                       9
<PAGE>

     months prior to the commencement of any payment or distribution of the
     amounts credited to the Participant's Deferred Bonus Account, a Participant
     in this portion of the Plan may file a written request with regard to the
     method of payment (i.e., a series of installments versus lump-sum payout),
     on a form prescribed by the Committee, which will revoke all such earlier
     or prior elections with regard to the method of payment (i.e., a series of
     installments versus lump-sum payout), and such new choice as to method of
     payment will be applied both to amounts previously credited to the
     Participant's current Deferred Bonus Account balance, as well as to amounts
     to be credited to such Deferred Bonus Account balance prospectively. Any
     such new or subsequent election that is made less than twelve (12) months
     prior to the commencement of any payment or distribution of the amounts
     credited to the Participant's Deferred Bonus Account, will be null and
     void, and the Participant's next preceding timely election will be
     reinstated.

          (b)  Change in Method of Payment Following Commencement of
     Distribution or Payment. After payment or distribution of amounts credited
     to the Participant's Deferred Bonus Account has commenced, the Participant
     may not change the period of time for which such amounts are payable.
     However the Participant may convert installment payments to a lump sum
     distribution subject to a penalty equal to a five percent (5%) reduction in
     the balance of the Participant's Deferred Bonus Account, which shall be
     forfeited to the Company.


                                   ARTICLE V

                               Change in Control

     5.1  Acceleration of Payment Upon Change in Control.  The terms of this
Section 5.1 shall immediately become operative, without further action or
consent by any person or entity, upon a Change in Control, and once operative
shall supersede and control over any other provisions of this Plan. Upon the
occurrence of a Change in Control, and for twelve (12) months thereafter, each
Participant, whether or not he or she is still an employee of the Company, shall
have the right to withdraw, in a single lump-sum cash payment, an amount equal
to ninety-five percent (95%) of the balance of such Participant's Deferred Bonus
Account, as of the valuation date immediately preceding the date of withdrawal;
provided, however, that if this option is exercised, such Participant will
forfeit to the Company the remaining five percent (5%) of the balance of each
such account (as of the valuation date immediately preceding the date of
withdrawal) from which the funds are withdrawn as a penalty. Payments under this
Section 5.1 shall be made as soon as practicable, but no later than thirty (30)
days after the Participant notifies the Company in writing that he/she is
exercising his/her right to withdraw pursuant to this Section 5.1.

     5.2  Amendment on or after Change in Control.  On or after a Change in
Control, no action, including by way of example and not of limitation, the
amendment, suspension or termination of the Plan, shall be taken which would
affect the rights of any Participant or the operation of this Plan with respect
to the balance in the Participant's Accounts.

     5.3  Attorney's Fees.  The Company shall pay all legal fees and related
expenses incurred by a Participant in seeking to obtain or enforce any payment,
benefit or right such Participant may be entitled to under the plan after a
Change in Control. The Participant shall reimburse the

                                       10
<PAGE>

Company for such fees and expenses at such time as a court of competent
jurisdiction, or another independent third party having similar authority,
determines that the Participant's claim was frivolously brought without
reasonable expectation of success on the merits thereof.

                                   ARTICLE VI

                          Designation of Beneficiaries

     The Participant shall name a beneficiary to receive any payments due such
Participant at the time of death, with the right to change such beneficiary at
any time.  In case of a failure of designation or the death of the designated
beneficiary without a designated successor, distribution shall be made to the
person or persons designated as beneficiary in the designation most recently
filed under the Sunoco, Inc. Capital Accumulation Plan, or if no such
designation has been made or the Participant is not participating in such plan,
the surviving spouse of a deceased Participant, or, if there is no surviving
spouse, the children of the Participant in equal shares (the share of any child
who predeceases the Participant to go in equal shares to the issue of such
deceased child), or if there is no surviving spouse, child, or issue of such
children, the estate of the Participant. No designation of beneficiaries shall
be valid unless in writing signed by the Participant, dated and filed with the
Company. Upon the Participant's death, any balance in the Participant's Deferred
Bonus Account is payable under the method elected by the Participant or in such
other manner as the Committee may determine in its sole discretion.

                                  ARTICLE VII

                                 Miscellaneous

     7.1  Source of Payments.  All payments of deferred bonuses shall be paid in
cash from the general funds of the Company and the Company shall be under no
obligation to segregate any assets in connection with the maintenance of the
Deferred Bonus Account, nor shall anything contained in this Plan nor any action
taken pursuant to the Plan create or be construed to create a trust of any kind,

in the Participant's Deferred Bonus Account shall be appropriately adjusted by
the Committee in the event of changes in the Company's outstanding common stock

consolidation, split-up, combination, exchange of shares or the like, and such
adjustments shall be conclusive.

     7.6  Termination and Amendment.  The Plan may be terminated at any time by
the Board of Directors of Sunoco, Inc., and may be amended at any time by the
Committee provided, however, that no such amendment or termination shall
adversely affect the rights of Participants or their beneficiaries with respect

                           SAVINGS RESTORATION PLAN
                 (Amended and Restated as of February 3, 2000)


I.   STRUCTURE OF THE PLAN

     The Sunoco, Inc. Savings Restoration Plan ("Plan") is established for the
     purpose of providing for certain employees benefits which otherwise would
     be lost by reason of the restrictive provisions of Section 401(a)(17) and
     Section 415 of the Internal Revenue Code of 1986, as amended (the "Code")
     applicable to the Sunoco, Inc. Capital Accumulation Plan ("SunCAP").  This
     Plan is the result of the merger of the Sun Company, Inc. Savings
     Restoration Plan II ("Plan II") into the Plan, effective December 21, 1995.
     The provisions of the Plan and Plan II prior to the effective date of the
     merger will remain effective with regard to those contributions.

     This Plan is an unfunded plan maintained primarily for the purpose of
     providing deferred compensation for a select group of management or highly
     compensated employees within the meaning of Sections 3(36), 201(2),
     301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of
     1974.

II.  ADMINISTRATION OF THE PLAN

     The Plan Administrator (as this term is defined in SunCAP), or its
     delegate, ("Plan Administrator") shall administer the Plan. The Plan
     Administrator shall have full authority to determine all questions arising
     in connection with the Plan. The Plan Administrator will also interpret the
     Plan, adopt procedural rules, and may employ and rely on such legal
     counsel, such actuaries, such accountants and such agents as it may deem
     advisable to assist in the administration of the Plan. Decisions of the
     Plan Administrator shall be conclusive and binding on all persons.

III. PARTICIPATION IN THE PLAN

     The Plan Administrator shall select the employees eligible to participate
     in the Plan for the next succeeding calendar year from among the
     participants in SunCAP whose employing corporation participates in SunCAP
     and adopts this Plan (hereinafter referred to as a "participating employer"
     which term also includes Sunoco, Inc. (the "Company")).  The participants
     in SunCAP selected for participation in this Plan shall be those SunCAP
     participants that the Plan Administrator reasonably

                                       1
<PAGE>

     believes will have compensation in excess of the limitations on
     compensation imposed under the terms of SunCAP by reason of Sections
     401(a)(17) of the Code (the "Compensation Cap") and/or will exceed the
     limitations on contributions imposed under the terms of SunCAP by reason of
     Section 415 of the Code ("Annual Additions Limit") during the succeeding
     calendar year.

IV.  BENEFITS PROVIDED UNDER THE PLAN

     1.   Participant Contributions

          A.   Compensation Cap Limitation. If a participant's Basic
               Contributions (as this term is defined in SunCAP) to SunCAP may
               be limited due to the imposition of the Compensation Cap, the
               participant may elect, before the beginning of the calendar year
               during which the participant is subject to the Compensation Cap,
               to contribute on a pretax basis to the participating employer by
               which the participant is employed, any remaining percentage of
               such Basic Contributions which the participant was otherwise
               prevented from making.

          B.   Annual Additions Limitation. If a participant's Basic
               Contributions to SunCAP may be limited due to the imposition of
               the Annual Additions Limit, the participant may elect, before the
               beginning of the calendar year during which the Annual Addition
               Limit is reached, to contribute on a pretax basis to the
               participating employer by which the participant is employed, any
               remaining percentage of such Basic Contributions which the
               participant was otherwise prevented from making.

          C.   Method of Making Participant Contributions. Participant
               contributions, as determined above, will be withheld from the
               compensation payable to the participant for services rendered to
               the participating employer after the date of the election and
               credited to a book account maintained for the participant by or
               on behalf of the participating employer as of the date such
               contributions would have been made to SunCAP. In determining the
               percentage of a participant's compensation to be contributed on a
               pretax basis under this Plan, no change in a participant's Basic
               Contributions during a calendar year for purposes of SunCAP shall
               be effective with respect to this Plan until the calendar year
               following the calendar year in which the change is made.
               Notwithstanding the foregoing, an election made by a participant
               under this Plan will be void if made after the beginning of the
               calendar

                                       2
<PAGE>

               year to which the election relates or the participant reduces his
               Basic Contributions during the calendar year to which the
               election relates.

     2.   Participating Employer Contribution

          A participant's participating employer shall maintain, or cause to be
          maintained, a book account for such participant to which the
          participating employer shall credit an amount equal to the Matching
          Employer Contributions (as this term is defined in SunCAP) that the
          participating employer would have made on the participant's behalf to
          SunCAP had the participant's Basic Contributions continued to be made
          to SunCAP, instead of to the participating employer under this Plan.

     3.   Nonforfeitability of and Earnings on Book Accounts

          A.   Nonforfeitability. All amounts credited to book accounts on
               behalf of participants shall be nonforfeitable.

          B.   Earnings. Participant and participating employer contributions
               will be credited to book accounts as of the date such
               contributions would have been made to SunCAP. All amounts
               credited to book accounts shall be deemed to have been invested
               in Fund C established under SunCAP and such book accounts shall
               be revalued monthly as if they had been invested in Fund C,
               except as provided in the following sentence. Effective January
               1, 1996, all amounts credited to book accounts shall be deemed to
               have been invested in any of the Funds established under SunCAP,
               and may be transferred among the Funds, in accordance with the
               elections made by the participant under this Plan, pursuant to
               procedures and limitations in effect under SunCAP.

V.   DISTRIBUTIONS

     1.   Lump-Sum Distribution

          Each participating employer shall distribute to each participant in
          the Plan employed by it for whom it maintains book accounts or his
          beneficiary under SunCAP an amount in cash equal to 100% of the value
          of his book account(s) attributable to all participant contributions
          and employer contributions made for calendar years prior to 1996 (and
          investment earnings on such contributions), and attributable to all
          participant contributions and employer contributions for calendar
          years after 1995 (and investment

                                       3
<PAGE>

          earnings on such contributions) for which an election has not been
          made pursuant to Section 2 of this Article V, upon the termination of
          employment of such participant under circumstances entitling him or
          his beneficiary to a distribution of the participant's interest in
          SunCAP whether or not a distribution is made at that time for SunCAP.

     2.   Ten-Year Certain Option

          Each participant may irrevocably elect, prior to the time a lump-sum
          distribution is required to be made pursuant to Section 1 of Article
          V, with respect to the value of the participant's book account(s)
          attributable to all participant contributions and employer
          contributions (and investment earnings on such contributions) for all
          years of the Plan, to waive the right to receive a lump-sum
          distribution of such contributions (and investment earnings on such
          contributions) (the "Ten-Year Certain Amounts") at termination of
          employment as provided in Section 1 of this Article V, and to receive
          a distribution of all Ten-Year Certain Amounts as determined under
          this Section 2.

          The Ten-Year Certain Amounts shall be distributed commencing no later
          than two months after the time lump-sum amounts are distributable
          pursuant to Section 1 of this Article V, in a series of annual
          distributions.  The participant will select the number (not to exceed
          ten) of such annual distributions.  The amount of each annual
          distribution shall be equal to the value of the account balance on the
          distribution date, divided by the number of annual distributions
          remaining as of the date the participant's account is valued for the
          annual distribution. The final annual distribution shall include 100%
          of the value of the participant's book account(s).

          Undistributed Ten-Year Certain Amounts shall remain credited to the
          participant's book account(s) and shall be deemed to be invested in
          accordance with the provisions of Section 3 of Article IV. In the
          event of the death of the participant prior to distribution of all
          Ten-Year Certain Amounts, any undistributed Ten-Year Certain Amounts
          shall be paid to the participant's beneficiary under SunCAP as soon as
          is administratively feasible.

     3.   Acceleration of Payment upon Change in Control

          A.   Right to Withdraw.

               The terms of this Section 3 of Article V shall immediately become
               operative, without further action or consent by any

                                       4
<PAGE>

               person or entity, upon a Change in Control, and once operative
               shall supersede and control over any other provisions of this
               Plan. Upon a Change in Control, and for twelve (12) months
               thereafter, each participant, whether or not he is still an
               employee of the Company, shall have the right to withdraw, in a
               single lump-sum cash payment, an amount equal to ninety-five
               percent (95%) of the value of his book accounts under the Plan;
               provided, however, that if this option is exercised, such
               participant will forfeit to the Company the remaining five
               percent (5%) of the value of his book accounts as of the time of
               the withdrawal. Payments under this Section 3 shall be made as
               soon as practicable, but no later than 30 days after the
               participant notifies the Plan that he is exercising his right to
               withdraw.

               (i)  On or after a Change in Control, no action, including by way
                    of example and not of limitation, the amendment, suspension
                    or termination of the Plan, shall be taken which would
                    affect the rights of any participant or the operation of the
                    Plan with respect to all amounts credited to book accounts
                    on behalf of participants on the date of the Change in
                    Control.

               (ii) The Company shall pay all reasonable legal fees and related
                    expenses incurred by a participant in seeking to obtain or
                    enforce any payment, benefit or other right such participant
                    may be entitled to under the Plan after a Change in Control;
                    provided, however, that the participant shall be required to
                    repay any such amounts to the Company to the extent a court
                    of competent jurisdiction issues a final and non-appealable
                    order setting forth the determination that the position
                    taken by the participant was frivolous or advanced in bad
                    faith.

          B.   Definitions.

               "Change in Control" shall be deemed to have occurred if:

               (i)  Continuing Directors cease, within one year of a Control
                    Transaction, to constitute a majority of the Board of
                    Directors of Sunoco, Inc. (or of the Board of Directors of
                    any successor to Sunoco, Inc. or to all or substantially all
                    of its assets) or

                                       5
<PAGE>

               (ii) any entity, person or Group acquires shares of Sunoco, Inc.
                    in a transaction or series of transactions that result in
                    such entity, person or Group directly or indirectly owning
                    beneficially more than twenty percent (20%) of the
                    outstanding voting shares.

               As used herein, "Control Transaction" shall mean any of the
               following transactions or any combination thereof: (1) any tender
               offer for or acquisition of capital stock of Sunoco, Inc., (2)
               any merger, consolidation, or sale of all or substantially all of
               the assets of Sunoco, Inc., or (3) the submission of a nominee or
               nominees for the position of director of the Company by a
               shareholder or a Group of shareholders in a proxy solicitation or
               otherwise. As used herein, "Continuing Director" shall mean a
               Director who was a member of the Board of Directors of Sunoco,
               Inc. immediately prior to a Control Transaction which results in
               a Change in Control. As used herein, "Group" shall mean persons
               who act in concert as described in Sections 13(d)(3) and/or
               14(d)(2) of the Securities Exchange Act of 1934, as amended.

     4.   Change in Method of Payment Following Commencement of Distribution or
          Payment.

          After payment or distribution of the value of the participant's book
          account(s) attributable to all participant contributions and employer
          contributions (and investment earnings on such contributions) for all
          years of the Plan, has commenced, the participant may not change the
          period of time for which such amounts are payable.  However the
          participant may convert installment payments (i.e., the "Ten-Year
          Certain Amounts" determined pursuant to Section 2 of this Article V)
          to a lump sum distribution, subject to a penalty equal to a five
          percent (5%) reduction in the balance of the value of the
          participant's book account(s) attributable to all participant
          contributions and employer contributions (and investment earnings on
          such contributions) for all years of the Plan.

VI.  GENERAL PROVISIONS

     1.   Right to Terminate

          This Plan may be terminated at any time by the Company.  The Company
          or any participating employer may terminate this Plan with respect to

          shall terminate SunCAP with respect to its

                                       6

          employees the amounts to their credit in their book accounts
          established under this Plan shall be distributed to such participants

          of contribution thereto.

     2.   Right to Amend

          This Plan may be amended at any time by the Board of Directors of the

          assignable or subject to attachment, execution, or levy of any kind.

     4.   Employment Relationships

          Nothing in this Plan shall be construed as giving any employee the

          Each participating employer in the Plan expressly reserves the right
          to dismiss any employee at any time without regard to the effect which

the applicable interest rate described in Treasury Regulation Section 1.417(e)-

          in the case of any such termination of employment by the Participant
          under this subsection 1.30(b), such termination shall not be deemed to
          be a Qualifying Termination unless the termination occurs within 120

     Company and Statutory Benefits.

          (b)  Section 3.03(a) shall not apply to limit that part of the benefit
     attributable to incentive compensation under subsection 1.19(b) to the
     extent that the Participant made an election to defer incentive
     compensation pursuant to the Sunoco, Inc. Deferred Compensation Plan.

     3.04 Minimum Normal Retirement Income.  Notwithstanding the foregoing, the
monthly normal retirement income which a Participant would otherwise be entitled
to receive under Section 3.02 will not be less than the excess of (a) over (b),
where

          (a)  equals 3-1/3% of his Final Average Earnings multiplied by the
     number of complete years of his Service up to a maximum of twelve (12) such
     years, and

          (b)  equals the sum of:

               (1)  100% of his Affiliated Company Benefit,

               (2)  100% of his Nonaffiliated Employer Benefit, plus

               (3)  100% of his Statutory Benefit.

     3.05 Early Retirement Date.  A Participant will be eligible to retire on an
early retirement date which will be the first day of any calendar month
coincident with or next following his 55th birthday if he has then completed at
least five (5) years of Executive Service.

     3.06 Early Retirement Income.  The monthly early retirement income payable
to the Participant commencing on his early retirement date will be equal to the
monthly normal retirement income that would otherwise be applicable under
Sections 3.02, 3.03 and 3.04, adjusted as follows:

          (a)  The Social Security Benefit referred to in Sections 3.02 and 3.04
     will be determined by projecting the Participant's Service to his Normal
     Retirement Date and assuming constant Earnings, at his last rate in effect,
     to Normal Retirement Date, and will then be multiplied by a fraction, the
     numerator of which will be his Service to the date of actual retirement and
     the denominator of which will be his projected Service to Normal Retirement
     Date.

          (b)  The amount calculated in subsection 3.02(a) will be reduced by
     5/12% for each full month by which actual retirement precedes Normal
     Retirement Date by more than five (5) years, and the offset for Social
     Security Benefits calculated in Sections 3.02(b) and 3.04 will be reduced
     by 7/12% for each full month that actual retirement precedes Normal
     Retirement Date during the five-year period immediately preceding Normal
     Retirement Date, and 7/24% for each full month that actual retirement
     precedes Normal Retirement Date by more than five (5) years.

                                       10

     3.07 Normal Form of Benefit.  Except as provided in Article IV, retirement
benefits under this Plan will be in the form of a lump sum payment of the
Actuarial Equivalent of the retirement income determined under Sections 3.02,
3.03, 3.04 and 3.06, whichever is applicable.

     3.08 Time of Payment.  The payment of a Participant's retirement benefits
shall be made or commence no later than the last day of the calendar month in
which the Participant retires.

     3.09 Increase in Monthly Benefits.  Effective July 1, 1998, the monthly
benefits of

          (a)  retirees who retired prior to January 1, 1981, as a result of
normal retirement under Section 3.01 or early retirement under Section 3.05,

          (b)  surviving Spouses, contingent annuitants or Beneficiaries of the
retirees described in subsection 3.09(a) who are receiving benefits on July 1,
1998, or

          (c)  surviving Spouses who began receiving surviving Spouse's benefits
under Section 5.04 or Section 5.05 prior to January 1, 1990,

shall be increased by the amount determined in the following sentence, subject,
however, to the limitation that the combined increases under the Base Plan and
the Plan effective July 1, 1998, shall not exceed $85.00.

     The monthly benefit increase shall be the excess of the sum of twenty
percent (20%) of the combined monthly benefit under the Base Plan and the Plan
up to $250.00, ten percent (10%) of the combined monthly benefit under the Base
Plan and the Plan in excess of $250.00 up to $500.00, three percent (3%) of the
combined monthly benefit under the Base Plan and the Plan in excess of $500.00
up to $750.00, and one percent (1%) of the combined monthly benefit under the
Base Plan and the Plan in excess of $750.00 up to $1,000, over the monthly
benefit increase effective July 1, 1998 under the Base Plan. Benefits payable on
account of disability shall not be increased. Fifty percent (50%) of these
retiree benefit increases shall be continued to the surviving Spouse; provided,
however, that any such increases in retirement income shall not be subject to
adjustments in effect at the time of the election or retirement reflecting the
cost of benefit increases under this Section.


                                  ARTICLE IV

                      Optional Forms of Retirement Income

     4.01 Election of an Optional Form of Payment. Not later than thirty (30)
days prior to a Participant's retirement date, a Participant may elect, in lieu
of the normal form of retirement benefits, an optional form of retirement
income. A Participant may not change or revoke an elected option unless such
change is made thirty (30) days prior to the Participant's retirement date. Each
election, designation and revocation of an option will be made in writing and in
conformity with such rules as may be prescribed by the Plan Administrator.
Notwithstanding the foregoing, a Spouse may not elect an optional form of
receiving any benefit payable under Article V.

     4.02 Monthly Annuity Option.  A Participant may elect to receive an annuity
which is equal to the monthly normal retirement income determined under Sections
3.02, 3.03, 3.04 and 3.06, whichever is applicable.

     4.03 Contingent Annuity Option. A Participant may elect to receive a
reduced retirement income, the amount of which will be determined by application
of appropriate Actuarially Equivalent

                                       11
<PAGE>

factors adopted by the Plan Administrator for the age and sex of the Participant
and the contingent annuitant. The contingent annuity option provides:

          (a)  payments to the Participant for life; and

          (b)  continuation of such payments, or any part of them designated by
     the Participant, to the contingent annuitant, if surviving, for life.

     4.04 Ten-Year Certain Option. A Participant may elect to receive a
retirement income of Actuarially Equivalent value payable for life, provided
that such income will be paid to such Participant or to the Beneficiary of such
Participant for ten (10) years after the Participant's retirement regardless of
whether the Participant or Beneficiary survives such period. At the discretion
of the Plan Administrator, any benefit payable hereunder to a Beneficiary may be
commuted and paid in one sum.

     4.05 Other Forms of Pension.  A Participant may elect to receive a benefit
payable over a period not less than the remaining lifetime of such Participant
and, if the Participant so further elects, thereafter to the designated
Beneficiary for as long as such designated Beneficiary survives the Participant
in such other form having an Actuarially Equivalent value as may be approved by,
and be subject to such conditions as may be prescribed by, the Plan
Administrator.

     4.06 Rules Applicable to Contingent Annuity Option.

          (a)  If the Participant should die before the effective date of the
     contingent annuity option, no benefit will be payable to the contingent
     annuitant.

          (b)  If the contingent annuitant should die before the effective date
     of the contingent annuity option, the option will automatically be
     cancelled and the normal monthly retirement income will be payable to the
     Participant as if the option had not been elected.

          (c)  If the contingent annuitant should die before the Participant but
     after the effective date of the contingent annuity option, benefits will be
     payable or continue to be paid to the Participant on the reduced basis;
     provided, however, that if the contingent annuitant should die during the
     first four years following commencement of the retirement income payments
     to the Participant, the amount of the reduced retirement income payable to
     the surviving retired Participant will be increased by restoring a
     percentage of the reduction amount as follows:

          Death of Contingent           Percentage of
          Annuitant During              Discount Restored
          -------------------           -----------------

          First Year                    80%

          Second Year                   60%

          Third Year                    40%

          Fourth Year                   20%

          Fifth and Subsequent Years     0%

          (d)  If the retirement date is earlier than the effective date of the
     contingent annuity option, retirement benefits commencing at the actual
     retirement date will be made on the

                                       12
<PAGE>

     normal form of retirement income. If the Participant and the contingent
     annuitant are living on such effective date, the retirement benefit will be
     adjusted to provide retirement income on and after such date in the
     optional form.

     4.07 Acceleration of Annuity Options. Notwithstanding the foregoing, if the
Internal Revenue Service makes a determination that the Participant must include
any amounts from the Plan in the taxable income of such Participant in a taxable
year prior to the year in which the Participant actually receives those amounts,
the Participant shall receive the Actuarial Equivalent of the remainder of the
benefit determined under Sections 3.02, 3.03, 3.04 and 3.06, whichever is
applicable. Such distribution shall be made no later than the last day of the
calendar year in which the Participant informs the Plan Administrator that the
Internal Revenue Service has made such a determination.

                                Death Benefits

     5.01 Preretirement Spouse's Death Benefit.  In the event of the death of a
Participant during active employment and after having become eligible to elect
an early retirement date, the Participant's Spouse will be entitled to a death
benefit payable in the normal form of payment pursuant to Section 5.02 in the
amount hereinafter set forth.  The amount of such monthly income will be twenty-
five percent (25%) of the monthly early retirement income that would have been
payable to the Participant under Section 3.06 had he retired on the date of his
death; provided, however, that:

          (a)  the reduction specified in Section 3.02(b)(2) with respect to the
     Participant's Affiliated Company Benefit will not be applicable;

          (b)  the early retirement reduction percentage described in subsection
     3.06(b) will be applied only to the offset for Social Security Benefits;

          (c)  the monthly income payments to the Spouse will be reduced by 1/2%
     for each year that the Spouse is more than ten (10) years younger than the
     Participant; and

          (d)  the amount payable to the Spouse will be reduced by any amount of
     Affiliated Company Benefits that are attributable to Affiliated Company
     contributions and that are payable to such Spouse.

     5.02 Normal Form of Preretirement Spouse's Death Benefit. Except as
otherwise elected pursuant to Section 5.03, the Preretirement Spouse's Death
Benefit will be in the form of a lump sum payment of the Actuarial Equivalent of
the Preretirement Spouse's Death Benefit determined under Section 5.01 payable
no later than the last day of the calendar month following the month in which
the Participant died.

     5.03 Election of Optional Form of Preretirement Spouse's Death Benefit.  A
Participant who is eligible to elect an early retirement date may:

     annuity pursuant to Section 5.04;

          (b)  elect the optional preretirement spouse's death benefit annuity
     pursuant to Section 5.05; or

                                       13
<PAGE>

          (c)  elect to have the optional Preretirement Spouse's Death Benefit
     annuity pursuant to Section 5.05 in a lump sum payment pursuant to Section
     5.06.

     A Participant may change or revoke an elected option at any time prior to
his actual retirement. Each election, designation and revocation of an option
will be made in writing and in conformity with such rules as may be prescribed
by the Plan Administrator.

     5.04 Preretirement Spouse's Death Benefit Annuity. If this form of payment
is elected by the Participant, the Participant's Spouse shall receive a
Preretirement Spouse's Death Benefit in the form of monthly payments commencing
no later than the last day of the calendar month following the month in which
the Participant died, payable over the lifetime of such Spouse.

     5.05 Optional Preretirement Spouse's Death Benefit Annuity.

          (a)  Amount of Benefit. If this form of payment is elected by the
     Participant, the Participant's Spouse shall receive a death benefit in the
     form of monthly payments commencing no later than the last day of the
     calendar month following the month in which the Participant died, payable
     over the lifetime of such Spouse in the amount hereinafter set forth. The
     amount of each such monthly income payment will be the sum of the monthly
     income payment under Section 5.04 and twenty-five percent (25%) of the
     monthly early retirement income that would have been payable to the
     Participant under Section 3.06 had he retired on the date of his death;
     provided, however, that;

               (1)  the reduction specified in subsection 3.02(b)(2) with
          respect to the Participant's Affiliated Company Benefit will not be
          applicable;

               (2)  the early retirement reduction percentage described in
          subsection 3.06(b) will be applied only to the offset for Social
          Security Benefits;

               (3)  the monthly income payments to the Spouse will be reduced by
          1/2% for each year that the Spouse is more than ten years younger than
          the Participant; and

               (4)  the amount payable to the Spouse will be reduced by any
          amount of Affiliated Company Benefits that are attributable to
          Affiliated Company contributions and that are payable to such Spouse.

          (b)  Reduction of Other Benefits. If this form of payment is elected
     by the Participant, the monthly amount of retirement benefit that becomes
     payable to either the Participant or Spouse under the plan will be reduced
     by an amount equal to 1/4% of:

               (1)  100% the monthly amount of early retirement income that
          would have been payable to the Participant under Section 3.06,
          determined as of his retirement date or, if earlier, as of his date of
          death on the assumption he had retired on that date; provided,
          however, that:

                    (i)   the reduction specified in subsection 3.02(b)(2) with
               respect to the Participant's Affiliated Company Benefits will not
               be applicable;

                    (ii)  the early retirement reduction percentage described in
               subsection 3.06(b) will be applied only to the offset for Social
               Security Benefits; and

                    (iii) any amount of Affiliated Company Benefits that are or
               would have been payable to the Spouse and that are attributable
               to Affiliated Company

                                       14
<PAGE>

               contributions will be subtracted from the monthly amount of
               income otherwise determined; multiplied by

               (2)  the number of full calendar years and any partial calendar
          year during which the Participant and his Spouse were living and the
          optional Preretirement Spouse's Death Benefit was in effect.

          This reduction shall also be in effect if the Participant chooses an
     optional preretirement lump sum death benefit pursuant to Section 5.06 of
     the Plan.

          (c)  When Coverage Will Take Effect. Unless otherwise specified by the
     Plan Administrator, the optional Preretirement Spouse's Death Benefit
     coverage will not take effect until the later of the date on which the
     Participant has met the age and Service requirements of Section 3.05 and
     the first day of the calendar month coincident with or next following the
     date the Participant's election was received by the Plan Administrator,
     provided that the Participant is alive, employed by the Company or an
     Affiliated Company and has not attained his Normal Retirement Date on the
     day such coverage would otherwise become effective.

          (d)  Revocation of Election. A Participant will have the right to
     revoke his election at any time before his actual retirement. Such election
     will be revoked automatically if the Participant ceases to have a Spouse;
     provided, however, that if such Participant subsequently acquires another
     Spouse, the coverage will automatically be reinstated unless revoked by the
     Participant.

          (e)  End of Coverage. The death benefit coverage provided for under
     this Section 5.05 will end upon the Participant's Normal or early
     Retirement Date.

     5.06 Optional Preretirement Lump Sum Death Benefit. If this form of payment
is elected by the Participant, the Participant's Spouse shall receive a death
benefit in the form of a lump sum payment of the Actuarial Equivalent of the
optional Preretirement Spouse's Death Benefit annuity determined under Section
5.05 payable no later than the last day of the calendar month following the
month in which the Participant died.

     5.07 Postretirement Spouse's Death Benefit.  In the event a Participant who
has elected to receive a retirement benefit in one of the optional forms
outlined in Article IV, dies after retiring or after attaining Normal Retirement
Date, the Spouse at the time of commencement of the distribution of such
retirement benefit will receive a monthly retirement income payable for the
lifetime of such Spouse in an amount equal to fifty percent (50%) of the
retirement income being paid or payable to the Participant (before giving effect
to any reduction in income required by the election of an optional form of
payment under Article IV); provided, however, that:

          (a)  the reduction specified in Section 3.02(b)(2) with respect to the
     Participant's Affiliated Company Benefit will not be applicable;

          (b)  the monthly income payable to the Spouse will be reduced by 1/2%
     for each year that the Spouse is more than ten years younger than the
     Participant; and

          (c)  the amount payable to the Spouse will be reduced by any amount of
     Affiliated Company Benefits that are attributable to Affiliated Company
     contributions and that are payable to such Spouse.

     The Spouse's death benefit payable under this Section 5.07 will be in
addition to any benefits otherwise payable under Article IV.

                                  ARTICLE VI

        Termination of Employment or Status as Executive; Re-employment

     6.01 Termination of Employment.

          (a)  Voluntary Termination. A Participant whose employment is
     terminated for any reason other than death or retirement, including early
     retirement, will not be entitled to benefits under this Plan, except as
     provided in subsection 6.01(b) and Section 6.04 hereof.

          (b)  Involuntary Termination. Notwithstanding any other provision of
     the Plan (and except as discussed herein), a Participant whose employment
     is involuntarily terminated prior to his Early Retirement Date, other than
     for Just Cause, and who executes a release and discharge of the Company
     from any and all claims, demands or causes of action other than as to
     amounts or benefits due to the Participant under any plan, program or
     contract provided by, or entered into with, the Company will be entitled to
     benefits in accordance with this subsection 6.01(b). Such release and
     discharge shall be in such form as prescribed by the Committee and shall be
     executed prior to the payment of any benefits due hereunder. In addition,
     no benefits due hereunder shall be paid to a Participant who is required by
     Company guidelines to execute an agreement governing the assignment of
     patents or the disclosure of confidential information unless an executed
     copy of such agreement is on file with the Company. The benefits under this
     subsection 6.01(b) shall consist of a nonforfeitable percentage in the
     benefits calculated under Section 3.06 (including the minimum benefit
     defined under Section 3.04) equal to 1-2/3% times the number of completed
     months of Executive Service. Such benefits shall commence coincident with
     or next following the first day of the calendar month in which the
     Participant attains age fifty-five (55), or if the Participant elects, the
     benefit will be paid no later than thirty (30) days after the Termination
     Date, in a lump sum payment of the Actuarial Equivalent of the age fifty-
     five (55) retirement income determined under Section 3.06, with an
     additional reduction of such benefit by discounting it to the date of
     payment using the interest rate used in Section 1.01. Any participant who
     also is eligible to receive benefits under Section 6.04 shall not receive
     benefits hereunder but shall instead receive the benefits under Section
     6.04.

     6.02 Termination of Executive Status.  If a Participant remains employed by
the Company or an Affiliated Company but ceases to be an Executive, he will
forfeit the right to all benefits under this Plan unless otherwise designated to
remain as a Participant by the Board Committee or unless he had attained his
55th birthday and completed at least five (5) years of Executive Service at the
time he ceased to be an Executive; provided, however, that the requirement that
the Participant have completed at least five years of Executive Service will be
waived in the case of any Participant who is an Executive on January 1, 1980 and
who has then attained his 55th birthday.  If any such participant is designated
at the Board Committee as being eligible to remain a Participant even though no
longer an Executive, the Participant will continue as such for all purposes of
this Plan.  If the Participant is not so designated by the Board Committee but
has attained his 55th birthday and, except for a Participant who was an
Executive on January 1, 1980 and who had then attained his 55th birthday, has
completed at least five years of Executive Service, he will remain a
Participant, but will be entitled to benefits based only upon his Service,
Credited Service and Final Average Earnings as of the date he ceased to be an
Executive.

     6.03 Reemployment. If a retired Participant is reemployed by the Company or
an Affiliated Company, his benefits will thereupon cease, and upon again
becoming such an Employee he will have his prior period of Service, Credited
Service and Executive Service restored to him. If he had made an election of an
optional form of payment, such election will continue on file with the Plan

                                       16
<PAGE>

Administrator, but no payment will be due under such option in the event of his
death before he again retires. Upon subsequent retirement his retirement income
will be based on his Service and Credited Service which was restored under this
Section 6.03 plus any Service and Credited Service rendered while employed as an
Executive after the time of his reemployment.

     6.04 Change in Control.

          (a)  Notwithstanding any other provisions in the Plan (including any
     minimum age and/or length of service requirements for vesting of benefits),
     a Participant shall become fully and irrevocably vested upon the earlier of
     a Qualifying Termination or a Change in Control of the Company and, upon
     either:

               (1)    the subsequent termination of this Plan, or any amendment
          to reduce any benefit due hereunder; or

               (2)    the subsequent termination of Participant's employment
          with the Company for any reason other than Just Cause,

          such Participant shall be entitled to benefits calculated as follows:

               (i)    Except for purposes of Section 1.11(b), Service and
          Credited Service shall be increased by 36 months, with the number of
          months credited under this Section 6.04(a)(i) reduced by one month for
          each completed month of Service of the Participant after the date of
          the Change in Control, but not below zero.

               (ii)   If at the Termination Date, the Participant has attained
          his Normal Retirement Date, he shall be entitled to a benefit
          calculated in accordance with Section 3.02

               (iii)  If at the Termination Date, the Participant has not
          attained his Normal Retirement Date, or has not attained his Early
          Retirement Date, he shall be entitled to benefits calculated under
          Section 3.06 (including the minimum benefit defined under Section
          3.04).

               (iv)   Final Average Earnings shall be determined using the
          greater of:

                      (A) the amount determined under Section 1.19 without

     shall be required to repay any such amounts to the Company to the extent a
     court of competent jurisdiction issues a final and non-appealable order
     setting forth the determination that the position taken by the Participant
     was frivolous or advanced in bad faith.

                              General Provisions

     9.01 Right to Amend or Terminate. The Company expects and intends to
continue the Plan indefinitely, but necessarily reserves the right, by action of
the Board of Directors, to amend, alter, suspend or terminate the Plan in whole
or in part, and at any time.

     9.02 Alienation of Benefits.  No benefits payable under the Plan will be
subject in any manner to anticipation, alienation, sale, transfer, assignment,
pledge, encumbrance or charge, and any action by way of anticipating,
alienating, selling, transferring, assigning, pledging, encumbering or charging
the same will be void and of no effect nor will any such benefit be in any
manner liable for or subject to the debts, contracts, liabilities, engagements
or torts of the person entitled to such benefit.

     9.03 Payment to Minors and Incompetents. If a Participant, Spouse,
contingent annuitant or Beneficiary entitled to receive any benefits hereunder
is a minor, or is deemed by the Plan Administrator or is adjudged to be legally
incapable of giving a valid receipt and discharge for such benefits, they will
be paid to the duly appointed guardian or committee of such minor or
incompetent, or they may be paid to such person or persons who the Plan
Administrator believes is or are caring for or supporting such minors or
incompetents. Any such payments, to the extent thereof, will be a complete
discharge for the payment of such benefit.

     9.04 Unclaimed Benefit. If any benefit under the Plan had been payable to
and unclaimed by any person for a period of four years since the whereabouts or
existence of such person was last known to the Plan Administrator, the Plan
Administrator may direct that all rights of such person to payments accrued and
to future payments be terminated absolutely, provided that if such person
subsequently appears and identifies himself to the satisfaction of the Plan
Administrator, then the liability will be reinstated.

     9.05 Plan Voluntary. The Plan is purely voluntary on the part of the
Company. Neither the establishment of the Plan, nor any amendment thereto, nor
the creation of any fund or account, nor the payment of any benefit will be
construed as conferring upon any Employee or Participant the right to be
retained in the employ of the Company or any Affiliated Company, and all
Employees and Participants will remain subject to discharge, discipline or
termination to the same extent as if the Plan had never been established.

     9.06 Gender.  Whenever used herein, the masculine pronoun will include the
feminine and the singular the plural, unless a different meaning is plainly
required by the context.

     9.07 Construction.  The Plan will be construed, enforced and administered
according to the laws of the Commonwealth of Pennsylvania.  In the event any
provision of the Plan is held illegal or invalid for any reason, it will not
affect the remaining provisions of the Plan, but the Plan will be construed and
enforced as if such illegal and invalid provision had not been included therein.

     than the Participant's present work location or a location within thirty-
     five (35) miles from the present location; or the Company requires the
     Participant to travel on Company business to an extent substantially more
     burdensome than such Participant's travel obligations during the period of
     twelve (12) consecutive months immediately preceding the Change in Control;

     provided, however, that in the case of any such termination of employment
by the Participant under this subparagraph (b), such termination shall not be
deemed to be a Qualifying Termination unless the termination occurs within 120
days after the occurrence of the event or events constituting the reason for the
termination; or

     (c) a termination of employment by the Company other than a termination for
Just Cause, or a termination of employment by the Participant for one of the
reasons set forth in (b) above, following a Potential Change in Control, if the
Participant can demonstrate that such termination or circumstance in (b) above
leading to termination:

          (1) was at the request of a third party with which the Company had
     entered into negotiations or an agreement with regard to a Change in
     Control; or

          (2) otherwise occurred in connection with, or in anticipation of, a
Change in Control;

                                       6

          provided, however, that in either such case, such Change in Control
     actually occurs within one (1) year following the Employment Termination
     Date.

     Section 1.27  "Tax Counsel" shall have the meaning provided herein at
Section 4.7(b).

                                  ARTICLE II

                     BACKGROUND, PURPOSE AND TERM OF PLAN

     Section 2.1  Background. Sunoco, Inc. maintains this Plan for the purpose
of providing severance allowances to Executive Resource Employees whose
employment is terminated in connection with or following a Change in Control.
The Plan shall be effective as of September 4, 1997.

     Section 2.2  Purpose of the Plan. The Plan, as set forth herein, has been
adopted by the Board of Directors of the Company, or a committee thereof,
delegated such responsibility, acting in its sole discretion, in recognition
that the possibility of a major transaction or a change in control of the
Company exists and that such possibility, and the uncertainty and questions
which it may raise among management, may result in the departure or distraction
of key management personnel to the detriment of the Company. The Board of
Directors has determined that appropriate steps should be taken to reinforce and
encourage the continued attention and dedication of Participants, as key members
of Company's management, to their assigned duties without distraction. The Plan
is not intended to be included in the definitions of "employee pension benefit
plan" and "pension plan" set forth under Section 3(2) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"). Rather, this Plan is intended
to meet the descriptive requirements of a plan constituting a "severance pay
plan" within the meaning of regulations published by the Secretary of Labor at
Title 29, Code of Federal Regulations, Section 2510.3-2(b). Accordingly, the
benefits paid by the Plan are not deferred compensation.

     Section 2.3  Term of the Plan. The Plan will continue until such time as
the Board of Directors, or a committee thereof, delegated such responsibility,
acting in its sole discretion, elects to modify, supersede or terminate it;
provided, however, that effective upon a Change in Control, no such action may
terminate or reduce the benefits or prospective benefits of any Participant on
the date of reference without the express written consent of the Participant.


                                  ARTICLE III

                  PARTICIPATION AND ELIGIBILITY FOR BENEFITS

     Section 3.1  General Requirements. Each Executive Resource Employee shall
become a Participant upon confirmation of his/her official title or employment
grade by election by the Board of Directors or appointment by the Company.
Except with respect to the benefits and

                                       7
<PAGE>

payments under Sections 4.7 and 4.8, in order to receive a Benefit under this
Plan, a Participant's employment must have been terminated as a result of a
Qualifying Termination.

     Section 3.2  Qualifying Termination. The Committee shall determine whether
any termination of a Participant is a Qualifying Termination. The Participant
shall follow the procedures described in Article IX for presenting his or her
claim for Benefits under this Plan.


                                  ARTICLE IV

                                   BENEFITS

     Section 4.1  Amount of Immediate Cash Benefit; Qualifying Termination. In
the event of a termination of employment that would qualify the Participant for
Benefits that is a Qualifying Termination, the cash amount to be paid to a
Participant eligible to receive Benefits under Section 3.1 hereof shall be paid
in a lump sum as provided in Section 5.1 hereof and shall equal the sum of the
following:

          (a) An amount equal to the Participant's earned vacation (as
     determined under the Company's applicable vacation policy as in effect at
     the time of the Change in Control) through his or her Employment
     Termination Date;

          (b)  (1) for the Chief Executive Officer, Chief Operating Officer, and
          Chief Financial Officer, Annual Compensation multiplied by three (3);

               (2) for an Executive Resources Employee in Grade 17 or above,
          Annual Compensation multiplied by two (2);

               (3) for each other Executive Resources Employee, Annual
          Compensation multiplied by one and one-half (1-1/2).

     Section 4.2  Executive Severance Benefits.  In the event that Benefits are
paid under Section 4.1, the Participant shall continue to be entitled, through
the end of his/her Benefit Extension Period, to those employee benefits, based
upon the amount of coverage or benefits provided at the Change in Control,
listed below:

          (a) death benefits as follows:

               (1) for Participants who became Executive Resource Employees on
          or after January 1, 1985, an amount equal to one (1) times annual base
          salary at the Employment Termination Date; and

               (2) for Participants who became Executive Resource Employees
          before January 1, 1985, an amount equal to two (2) times the sum of
          annual base salary and guideline bonus at the Employment Termination
          Date;

          Any supplemental coverages elected under the Sunoco, Inc. Death
     Benefits Plan (or any similar plan of any of the following: a subsidiary or
     affiliate which has adopted

                                       8
<PAGE>

     this Plan; a corporation succeeding to the business of Sunoco, Inc.; and/or
     any subsidiary or affiliate, by merger, consolidation, liquidation,
     purchase of assets or stock, or similar transaction) will be discontinued
     under the terms of such plan or plans; and

          (b) medical plan benefits (excluding dental coverage), including COBRA
     continuation coverage following the Benefit Extension Period (i.e., COBRA
     continuation eligibility will begin as of the end of the Benefit Extension
     Period, except as provided hereinbelow at Section 4.3).

     In each case, when contributions are required of all Executive Resource
Employees at the time of the Participant's Employment Termination Date, or
thereafter, if required of all other active Executive Resource Employees, the
Participant shall continue to be responsible for making the required
contributions during the Benefit Extension Period in order to be eligible for
the coverage. In lieu of the coverages provided under clauses (a) and (b) above,
the Company may pay, at the time payment is otherwise to be made of cash
Benefits pursuant to Section 5.1 hereof, the Participant an amount (as adjusted
for taxes) equal to the then present value of the Company's cost of such
coverages, or the Company may provide the Participant with comparable coverage
under a policy of insurance. The Participant also shall be entitled to
outplacement services during the Benefit Extension Period, at no cost to the
Participant, from an experienced third-party vendor selected by the Committee
and consistent with vendors used in connection with the Sunoco, Inc. Involuntary
Termination Plan at the Change in Control.

     Section 4.3  Special Medical Benefit. In the event Benefits are paid to the
Participant under Section 4.1:

          (a) Participants who are fifty (50) or more years of age on the
     Employment Termination Date, with ten (10) or more years of Company
     Service, shall have medical (but not dental) benefits available under the
     same terms and conditions as other employees not yet eligible for Medicare
     coverage who retire under the terms of a Company retirement plan.

          (b) Participants who were fifty (50) or more years of age on the
     Employment Termination Date, but with fewer than ten (10) years of Company
     Service, nonetheless shall have Company medical plan benefits (excluding
     dental coverage) available following the Severance Benefit Period, at a
     cost to such Participant that is equal to the full premium cost of such
     coverage.

     Such benefits continue until such time as the Participant becomes first
eligible for Medicare, or the Participant voluntarily cancels coverage,
whichever is earliest.

     Section 4.4  Retirement Plans. This Plan shall not govern and shall in no
way affect the Participant's interest in, or entitlement to benefits under, any
of the Company's "qualified" or supplemental retirement plans and any payments
received under any such plans shall not affect a Participant's right to any
Benefit hereunder.

     Section 4.5  Minimum Benefit. Notwithstanding the provisions of Sections
4.1, 4.2 and 4.3 hereof, the Benefits available under this Plan shall not be
less than those determined in accordance with the provisions of the Sunoco, Inc.
Special Employee Severance Plan. If the

                                       9
<PAGE>

Participant determines that the benefits under the Sunoco, Inc. Special Employee
Severance Plan are more valuable to the Participant than the comparable Benefits
set forth in this Plan, then the provisions used to calculate the Benefits
available to the Participant under this Plan shall not apply, and the Benefits
available to the Participant under this Plan shall be calculated using only the
applicable provisions of the Sunoco, Inc. Special Employee Severance Plan.


     Section 4.6  Effect on Other Benefits.  There shall not be drawn from the
continued provision by the Company of any of the aforementioned Benefits any
implication of continued employment or of continued right to accrual of
retirement benefits under the Company's qualified or supplemental retirement
plans, nor shall a terminated employee, except as otherwise provided under the
terms of the Plan, accrue vacation days, paid holidays, paid sick days or other
similar benefits normally associated with employment for any part of the Benefit
Extension Period during which benefits are payable under this Plan.  A
Participant shall have no duty to mitigate with respect to Benefits under this
Plan by seeking or accepting alternative employment.  Further, the amount of any
payment or benefit provided for in this Plan shall not be reduced by any
compensation earned by the Participant as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Participant to the Company, or otherwise.

     Section 4.7  Parachute Payments.

          (a) Whether or not the Participant becomes entitled to Benefits under
     Section 4.1, if any payment or benefit received or to be received by the
     Participant in connection with a Change in Control or the termination of
     the Participant's employment (all such payments and benefits, including the
     Benefits under Sections 4.1, 4.2 and 4.3, being hereinafter the "Total
     Payments"), whether pursuant to the terms of:


               (1) this Plan; or

               (2) any other plan, arrangement or agreement with:


                    (i)   the Company;

                    (ii)  any person whose actions result in a Change in
               Control; or

                    (iii) any person affiliated with the Company or with any
               person whose actions result in a Change in Control;


     will be subject (in whole or part) to the excise tax under section 4999 of
     the Code (the "Excise Tax"), then the Company shall pay to the Participant
     an additional amount (the "Gross-Up Payment") such that the net amount
     retained by the Participant, after deduction of any Excise Tax on the Total
     Payments and any federal, state and local income and employment tax and
     Excise Tax upon the Gross-Up-Payment, shall be equal to the Total Payments.
     For purposes of determining the amount of the Gross-Up Payment, the
     Participant shall be deemed to pay federal income and employment taxes at
     the highest marginal rate of federal income and employment taxation in the
     calendar year in which the Gross-Up Payment is to be made (the "Payment
     Date") and state and local income taxes at the highest marginal rate of
     taxation in the state and locality of the

                                       10
<PAGE>

     Participant's residence on the Payment Date, net of the maximum reduction
     in federal income taxes which could be obtained from deduction of such
     state and local taxes.

          (b) For purposes of determining whether any of the Total Payments will
     be subject to the Excise Tax and the amount of such Excise Tax:

               (1) all of the Total Payments shall be treated as "parachute
          payments" within the meaning of section 280G(b)(2) of the Code, unless
          in the opinion of tax counsel (the "Tax Counsel") reasonably
          acceptable to the Participant and selected by the accounting firm (the
          "Auditor") which was, immediately prior to the Change in Control, the
          Company's independent auditor, such other payments or benefits (in
          whole or in part) do not constitute parachute payments, including by
          reason of section 280G(b)(4)(A) of the Code;

               (2) all "excess parachute payments" within the meaning of section
          280G(b)(1) of the Code shall be treated as subject to the Excise Tax
          unless, in the opinion of Tax Counsel, such excess parachute payments
          (in whole or part) represent reasonable compensation for services
          actually rendered, within the meaning of section 280G(b)(4)(B) of the
          Code, in excess of the "base amount" within the meaning set forth in
          section 280G(b)(3) of the Code allocable to such reasonable
          compensation, or are otherwise not subject to the Excise Tax; and

               (3) the value of any noncash benefits or any deferred payment or
          benefit shall be determined by the Auditor in accordance with the
          principles of section 280G(d)(3) and (4) of the Code.

          Prior to the payment date set forth in Section 4.7(d) hereof, the
     Company shall provide the Participant with its calculation of the amounts
     referred to in this Section 4.7(b) and such supporting materials as are
     reasonably necessary for the Participant to evaluate the Company's
     calculations.  If the Participant disputes the Company's calculations (in
     whole or in part), the reasonable opinion of Tax Counsel with respect to
     the matter in dispute shall prevail.

          (c) In the event that:

               (1) amounts are paid to the Participant pursuant to Section
          4.7(a) above; and

               (2) the Excise Tax is subsequently determined to be less than the
          amount taken into account hereunder at the time of termination of the
          Participant's employment,

          the Participant shall repay to the Company, at the time that the
     amount of such reduction in Excise Tax is finally determined, the portion
     of the Gross-Up Payment attributable to such reduction plus interest on the
     amount of such repayment at the rate provided in section 1274(b)(2)(B) of
     the Code.  In the event that the Excise Tax is determined to exceed the
     amount taken into account hereunder at the Payment Date (including by
     reason of any payment the existence or amount of which cannot be

                                       11
<PAGE>

     determined at the time of the Gross-Up Payment), the Company shall make an
     additional Gross-Up Payment to the Participant in respect of such excess
     (plus any interest, penalties or additions payable by the Participant with
     respect to such excess and such portion) at the time that the amount of
     such excess is finally determined.

          (d) The payments provided for in subsections (a) and, if applicable,
     (c) of this Section 4.7 shall be made not later than the ninetieth (90th)
     day following the Change in Control if payments are due at that time, or
     the Employment Termination Date, if payments are then due; provided,
     however, that if the amounts of such payments, or, if applicable, the
     Excise Tax, cannot be finally determined on or before such day, the Company
     shall pay to the Participant on such day an estimate, as determined in good
     faith by the Participant, of the minimum amount of such payments to which
     the Participant is clearly entitled and shall pay the remainder of such
     payments (together with interest at the rate provided in section
     1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined
     but in no event later than the thirtieth (30th) day after the date payment
     is due.  In the event that the amount of the estimated payments exceeds the
     amount subsequently determined to have been due, such excess shall
     constitute a loan by the Company to the Participant, payable on the fifth
     (5th) business day after demand by the Company (together with interest at
     the rate provided in section 1274(b)(2)(B) of the Code).  At the time that
     payments are made under this Section, the Company shall provide the
     Participant with a written statement setting forth the manner in which such
     payments were calculated and the basis for such calculations including,
     without limitation, any opinions or other advice the Company has received
     from outside counsel, auditors or consultants (and any such opinions or
     advice which are in writing shall be attached to the statement).

          (e) All of the fees and expenses of the Tax Counsel and Auditor in
     performing the determinations referred to in subsections (b) and (c) above
     shall be borne solely by the Company.  The Company agrees to indemnify and
     hold harmless the Tax Counsel and Auditor of and from any and all claims,
     damages and expenses resulting from or relating to its determinations
     pursuant to subsections (b) and (c) above, except for claims, damages or
     expenses resulting from the gross negligence or willful misconduct of the
     Tax Counsel or Auditor.

     Section 4.8  Legal Fees and Expenses.  The Company also shall pay to the
Participant all legal fees and expenses incurred by the Participant:

          (a) in disputing in good faith any issue relating to the termination
     of the Participant's employment following a Change in Control as a result
     of a Qualifying Termination entitling the Participant to Benefits under
     this Plan (including a termination of employment following a Potential
     Change in Control if the Participant alleges in good faith that such
     termination will be or is a Qualifying Termination pursuant to Section 1.18
     hereof, and the Change in Control actually occurs within one (1) year
     following the Employment Termination Date); or

          (b) in seeking in good faith to obtain or enforce any benefit or right
     provided by this Plan (or the payment of any Benefits through any trust
     established to fund Benefits under this Plan) or in connection with any tax
     audit or proceeding to the extent

                                       12
<PAGE>

     attributable to the application of section 4999 of the Code to any payment
     or benefit provided hereunder.

     Such payments shall be made as such fees and expenses are incurred by the
Participant, but in no event later than five (5) business days after delivery of
the Participant's written requests for payment accompanied with such evidence of
fees and expenses incurred as the Company reasonably may require.  The
Participant shall reimburse the Company for such fees and expenses at such time
as a court of competent jurisdiction, or another independent third party having
similar authority, determines that the Participant's claim was frivolously
brought without reasonable expectation of success on the merits thereof.

within fifteen (15) days after the Participant's Employment Termination Date but
in no event later than thirty (30) days thereafter. In the event the Company
should fail to pay when due the amounts described in Article IV, the Participant
shall also be entitled to receive from the Company an amount representing
interest on any unpaid or untimely paid amounts from the due date, as determined
under Section 4.7(d), to the date of payment at a rate equal to the prime rate
of Citibank, N.A. as in effect from time to time after such due date.

such Benefits.  Such beneficiary designation shall be made in the manner, and at
the time, prescribed by the Company in its sole discretion.  In the absence of
an effective beneficiary designation hereunder, the Participant's estate shall
be deemed to be his or her designated beneficiary.


                                  ARTICLE VI

respective duties as members of the Committee and shall provide coverage to them
under the Company's Liability Insurance program(s).

     Section 6.7  Records, Reporting and Disclosure.  The Committee shall keep
all individual and group records relating to Participants and former
Participants and all other records necessary for the proper operation of the
Plan.  Such records shall be made available to the Company and to each
Participant for examination during business hours except that a Participant
shall examine only such records as pertain exclusively to the examining
Participant and to the Plan.  The Committee shall prepare and shall file as
required by law or regulation all reports, forms, documents and other items
required by ERISA, the Internal Revenue Code, and every other relevant statute,
each as amended, and all regulations thereunder (except that the Company, as

Chief Executive Officer.  Whenever a determination is required of the Chief
Executive Officer as to any matter that directly pertains to, or affects, the
Chief Executive Officer under the Plan, such determination with respect to the
Chief Executive Officer shall be made and approved by a majority of the
Continuing Directors, or, if there are no Continuing Directors, then by at least
three quarters (3/4) of the entire Board of Directors.

     Section 7.1  Amendment, Suspension and Termination.  The Company, acting
through the Board of Directors, retains the right, at any time and from time to
time, to amend, suspend or terminate the Plan in whole or in part, for any
reason, and without either the consent of or the prior notification to any
Participant.  Notwithstanding the foregoing, effective upon a Change in Control,
no such action may terminate or reduce the benefits or prospective benefits of
any Participant on the date of reference without the express written consent of
the Participant.  No such amendment, suspension or termination shall give the
Company the right to recover any amount paid to a Participant prior to the date
of such amendment or to cause the cessation and discontinuance of payments of
Benefits to any person or persons under the Plan already receiving Benefits.
The Board of Directors shall have the right to delegate its authority and powers
hereunder, or any portion thereof, to any committee of the Board of Directors,
and shall have the right to rescind any such delegation in whole or in part.

                               CLAIMS PROCEDURES

     Section 9.1  Application for Benefits.  Benefits shall be paid by the
Company following an event that qualifies the Participant for Benefits.  In the
event a Participant believes himself/herself eligible for Benefits under this
Plan and Benefit payments have not been initiated by the Company, the
Participant may apply for such Benefits by requesting payment of Benefits in
writing from the Committee.

     Section 9.2  Appeals of Denied Claims for Benefits.  In the event that any
claim for benefits is denied in whole or in part, the Participant (or
beneficiary, if applicable) whose claim has been so denied shall be notified of
such denial in writing by the Committee, within thirty (30) days following
submission by the Participant (or beneficiary, if applicable) of such claim to
the Committee.  The notice advising of the denial shall specify the reason or
reasons for denial, make specific reference to pertinent Plan provisions,
describe any additional material or information necessary for the claimant to
perfect the claim (explaining why such material or information is needed), and
shall advise the Participant of the procedure for the appeal of such denial.
All appeals shall be made by the following procedure:

          (a) The Participant whose claim has been denied shall file with the
     Committee a notice of desire to appeal the denial.  Such notice shall be
     filed within sixty (60) days of notification by the Committee of the claim
     denial, shall be made in writing, and shall set forth all of the facts upon
     which the appeal is based.  Appeals not timely filed shall be barred.

          (b) The Committee shall, within thirty (30) days of receipt of the
     Participant's notice of appeal, establish a hearing date on which the
     Participant may make an oral presentation to the Committee in support of
     his/her appeal.  The Participant shall be given not less than ten (10)
     days' notice of the date set for the hearing.

          (c) The Committee shall consider the merits of the claimant's written
     and oral presentations, the merits of any facts or evidence in support of
     the denial of benefits, and such other facts and circumstances as the
     Committee shall deem relevant.  If the claimant elects not to make an oral
     presentation, such election shall not be deemed adverse to his/her
     interest, and the Committee shall proceed as set forth below as though an
     oral presentation of the contents of the claimant's written presentation
     had been made.

          (d) The Committee shall render a determination upon the appealed
     claim, within sixty (60) days of the hearing date, which determination
     shall be accompanied by a written statement as to the reasons therefor.

                                 MISCELLANEOUS

     Section 10.1  Nonalienation of Benefits.  None of the payments, benefits or
rights of any Participant shall be subject to any claim of any creditor, and, in
particular, to the fullest extent permitted by law, all such payments, benefits
and rights shall be free from attachment, garnishment, trustee's process, or any
other legal or equitable process available to any creditor of such Participant.
No Participant shall have the right to alienate, anticipate, commute, pledge,
encumber or assign any of the benefits or payments which he/she may expect to
receive, contingently or otherwise, under this Plan.

     Section 10.2  No Contract of Employment.  Neither the establishment of the
Plan, nor any modification thereof, nor the creation of any fund, trust or
account, nor the payment of any benefits shall be construed as giving any
Participant, or any person whosoever, the right to be retained in the service of
the Company, and all Participants shall remain subject to discharge to the same
extent as if the Plan had never been adopted.

     Section 10.3  Severability of Provisions.  If any provision of this Plan
shall be held invalid or unenforceable, such invalidity or unenforceability
shall not affect any other provisions hereof, and this Plan shall be construed
and enforced as if such provisions had not been included.

     Section 10.4  Successors, Heirs, Assigns, and Personal Representatives.
This Plan shall be binding upon the heirs, executors, administrators, successors
and assigns of the parties, including each Participant, present and future.

     Section 10.5  Headings and Captions.  The headings and captions herein are
provided for reference and convenience only, shall not be considered part of the
Plan, and shall not be employed in the construction of the Plan.

     Section 10.6  Gender and Number.  Except where otherwise clearly indicated
by context, the masculine and the neuter shall include the feminine and the
neuter, the singular shall include the plural, and vice-versa.

     Section 10.7  Unfunded Plan.  The Plan shall not be funded.  A
Participant's right to receive payment of Benefits hereunder shall be no greater
than the right of any unsecured creditor of the Company.  The Company may, but
shall not be required to, set aside or earmark an amount necessary to provide
the Benefits specified herein (including the establishment of trusts).  In any
event, no Participant shall have any right to, or interest in, any assets of the
Company which may be applied by the Company to the payment of Benefits except as
may be provided pursuant to the terms of any trust established by the Company to
provide Benefits.

     Section 10.8  Payments to Incompetent Persons, Etc.  Any Benefit payable to
or for the benefit of a minor, an incompetent person or other person incapable
of receipting therefor shall be deemed paid when paid to such person's guardian
or to the party providing or reasonably appearing to provide for the care of
such person, and such payment shall fully discharge the Company, the Committee
and all other parties with respect thereto.

                                       17

     Section 10.9  Lost Payees.  A Benefit shall be deemed forfeited if the
Committee is unable to locate a Participant to whom a Benefit is due.  Such
Benefit shall be reinstated if application is made by the Participant for the
forfeited Benefit while this Plan is in operation.

     Section 10.10 Controlling Law.  This Plan shall be construed and enforced
according to the laws of the Commonwealth of Pennsylvania to the extent not
preempted by federal law.

     Section 10.11 Successor Employer.  The Company shall require any successor
or assignee, whether direct or indirect, by purchase, merger, consolidation or
otherwise, to all or substantially all the business or assets of the Company,
expressly and unconditionally to assume and agree to perform the Company's
obligations under this Plan, in the same manner and to the same extent that the
Company would be required to perform if no such succession or assignment had
taken place.  In such event, the term "Company" shall mean the Company and any
successor or assignee to the business or assets which by reason hereof becomes
bound by the terms and provisions of this Plan.

                                  SUNOCO, INC.

                                First Amendment
                                       to
               Deferred Compensation and Benefits Trust Agreement

  This First Amendment to Deferred Compensation and Benefits Trust Agreement,
dated as of September 3, 1999 (the "First Amendment"), is by and among SUNOCO,
INC., a Pennsylvania corporation (the "Company"), BANKERS TRUST COMPANY, a New
York banking corporation (the "Trustee"), and TOWERS, PERRIN, FORSTER & CROSBY,
INC., a Pennsylvania corporation (the "Recordkeeper").  Initially capitalized
terms used herein and not otherwise defined shall have the respective meanings
assigned to such terms pursuant to that certain Deferred Compensation and
Benefits Trust Agreement, dated as of January 11, 1999, by and among the
Company, the Trustee, and the Recordkeeper (the "Trust").

                              W I T N E S S E T H

     WHEREAS, the Company previously has established the Trust, in order to:

          (1) provide an alternative source of funds to assist the Company in
     meeting its obligations, under certain employee benefit plans, agreements,
     or other arrangements, to make payments to Plan Participants and their
     beneficiaries; and

          (2) assure that future payment of such amounts would not be
     improperly withheld in the event of a change in control of the Company; and

     WHEREAS, it is the intention of the parties to amend the Trust in order to:

          (1) limit the level of funding of the Special Employee Severance Plan
     so that, upon the occurrence of any Potential Change in Control, only the
     benefits for those employees then in grades 11 through 13 will be fully
     funded;

          (2) make the Trust more difficult to amend following any Potential
              Change in Control; and

          (3) provide that the Trust shall become irrevocable upon the
              occurrence of any Potential Change in Control.

     WHEREAS, Bankers Trust Company is willing to act as Trustee of the Trust,
and Towers Perrin is willing to act as Recordkeeper of the Trust, upon all of
the terms and conditions contained in the Trust, as amended hereinafter by this
First Amendment.

     NOW THEREFORE, in consideration of the mutual terms, covenants, and
conditions herein contained, the mutual benefits to be derived hereunder, and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, and intending to be legally bound, the parties hereto agree
as follows:

     A. Effective as of September 3, 1999, the Trust is amended as follows:

          (1) by deleting the current Section 2.1 of the Trust in its entirety,
     and replacing it with the following text:

                                       1
<PAGE>

                    "2.1 Plans & Agreements Subject to Trust. The plans,
              agreements, and other arrangements that are subject to this Trust
              (each a "Plan" and, collectively the "Plans") are listed on
              Schedule 2.1 hereto. Prior to a Potential Change in Control of the
              Company, the Compensation Committee of the Board of Directors of
              the Company (the "Compensation Committee") may from time to time
              designate additional such plans, agreements, and other
              arrangements to be subject to this Trust, or delete any Plan from
              this Trust. The Company shall immediately notify the Trustee and
              the Recordkeeper in writing of any such changes. "

          (2) by deleting the current Section 3.2 of the Trust in its entirety,
     and replacing it with the following text:

                    "3.2 Term and Revocability. The Trust hereby established is
              revocable by the Company, but shall become irrevocable upon the
              occurrence of a Potential Change in Control. At any time following
              the occurrence of a Potential Change in Control of the Company,
              this Trust may not be terminated either by the Company or the
              Board of Directors (or any member or committee thereof). Upon or
              after a Change in Control of the Company, this Trust shall not
              terminate until the date on which Plan Participants and their
              beneficiaries are no longer entitled to benefits pursuant to the
              terms of the Plans. Upon termination of the Trust any assets
              remaining in the Trust shall be returned to the Company."

          (3) by deleting the current Section 7.3 of the Trust in its entirety,
     and replacing it with the following text:

                    "7.3 Company Information. As soon as practicable, but in no
              event later than fifteen (15) days, following the occurrence of
              any Potential Change in Control, the Recordkeeper shall identify
              to the Company in writing the information deemed necessary to
              enable the Recordkeeper to determine the amount of benefits
              payable to or with respect to each Plan Participant in each Plan,
              including any benefits payable after the Plan Participant's death,
              and the recipient. As soon as reasonably practicable after
              receiving such communication from the Recordkeeper following any
              Potential Change in Control, the Company shall furnish the
              information needed by the Recordkeeper in order to determine the
              amount of any such benefit, and shall deliver to the Recordkeeper
              a letter of instructions:

                    (a) describing the terms of each Plan;

                    (b) enclosing a copy of each Plan;

                    (c) listing the names, addresses, and Hay points or grade
                    levels under the salary administration program then in
                    effect, for the Plan Participants (and beneficiaries)
                    covered by each Plan;

                    (d) setting forth the timing, form of distributions, and
                    formula or other methodology for determining the amounts to
                    be paid to each Plan Participant and beneficiary under each
                    Plan; and

                    (e) instructing the Recordkeeper how and from whom to get
                    any other information needed to compute benefits under each
                    Plan.

                    Thereafter, the Company shall regularly, at least annually,
              furnish revised updated information to the Recordkeeper. In the
              event the Company refuses or neglects to provide updated Plan
              Participant information, as contemplated herein, the Recordkeeper
              shall be entitled to rely upon the most recent information
              furnished to it by the Company."

          (4) by deleting the current Section 7.4 of the Trust in its entirety,
     and replacing it with the following text:

                                       2
<PAGE>

                    "7.4 Payment Schedule. Within forty-five (45) days following
              a Change in Control or Potential Change in Control (or when the
              Company otherwise makes contributions to the Trust), the
              Recordkeeper, on behalf of the Company, shall deliver to the
              Trustee a schedule (the "Payment Schedule") that indicates:

                    (a) in the case of all Plans, except the Special Employee
                 Severance Plan, the amounts payable (including the fees and
                 expenses incurred by the Plans) in respect of each Plan
                 Participant (and his or her beneficiaries); and

                    (b) in the case of the Special Employee Severance Plan, the
                 amount reasonably expected to be payable thereunder, in order
                 to fully fund the benefits due to those Participants then in
                 grades 11 through 13, together with an explanation of the
                 assumptions used by the Recordkeeper in performing its
                 calculation.

                 The Payment Schedule shall be updated by the Recordkeeper as
              necessary, but on at least an annual basis, in order to reflect
              changes therein. Upon the termination of employees entitled to
              benefits under the Plans, the Company will notify the
              Recordkeeper, and the Recordkeeper will update the Payment
              Schedule to indicate those Plan Participants to whom benefits have
              become payable. Except as otherwise provided herein, the Trustee
              shall make payments to the Plan Participants and their
              beneficiaries in accordance with such Payment Schedule and shall
              pay such fees and expenses, unless paid by the Company. The
              Trustee shall make provision for the reporting and withholding of
              any federal, state or local taxes that may be required to be
              withheld with respect to the payment of benefits pursuant to the
              terms of the Plans and shall pay amounts withheld to the
              appropriate taxing authorities or determine that such amounts have
              been reported, withheld and paid by the Company."

          (5) by deleting the current Section 14.3 of the Trust in its entirety,
     and replacing it with the following text:

                 "14.3  Amendment or Waiver.

                     (a) Amendment Prior to Potential Change in Control. Prior
                 to the occurrence of any Potential Change in Control, this
                 Trust Agreement may be amended only by a written instrument
                 executed by the Trustee, the Recordkeeper and the Company. In
                 case of conflict between the terms of this Trust Agreement and
                 the terms of the Plans, the terms of the Trust Agreement shall
                 control; provided, however, that:

                         (1) provisions that, in the determination of the
                     Company, affect solely the Trustee may, at the option of
                     both the Trustee and the Company, be amended by a writing
                     executed only by the Company and the Trustee, with a copy
                     of such writing being provided to the Recordkeeper; and

                         (2) provisions that, in the determination of the
                     Company, affect solely the Recordkeeper may, at the option
                     of both the Recordkeeper and the Company, be amended by a
                     writing executed only by the Company and the Recordkeeper,
                     with a copy of such writing being provided to the Trustee.

                     (b) Amendment Following Potential Change in Control. Upon
                 and after the occurrence of any Potential Change in Control,
                 and unless otherwise required by applicable statute or
                 regulation, the following rules will govern amendments and

       then entitled to receive payments hereunder;

       eighty percent (80%) of the Plan Participants then entitled to receive

       Participant to any such waiver shall be valid if set forth in an
       instrument in writing signed on behalf of such party or Plan
       Participant."; and

+   Effective in the third quarter of 1995, Sunoco began paying quarterly divi-
    dends on preference stock at a rate of $.90 per share and reduced its quar-
    terly common stock dividend from $.45 to $.25 per share. On May 28, 1998,
    the Company redeemed all of its outstanding shares of preference stock. The
    cash dividends per share of preference stock for 1998 represent the divi-
    dends paid through the redemption date. (See Note 15 to the consolidated
    financial statements.)
++  Prior to 1998, assumes redemption of preference shares for common stock
    utilizing a ratio of two shares of common stock for each outstanding pref-
    erence share. The actual redemption of the preference shares occurred on
    May 28, 1998. (See Note 15 to the consolidated financial statements.)

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Those statements in the Management's Discussion and Analysis that are not his-
torical in nature should be deemed forward-looking statements that are inher-
ently uncertain. See "Forward-Looking Statements" on page 24 for a discussion
of the factors which could cause actual results to differ materially from those
projected.

Outlook
Sunoco's profitability is primarily determined by refined product margins and
the reliability and efficiency of Company operations. Beginning in the second
half of 1998, margins in Sunoco's principal refining centers in the Northeast
and Midwest and many of its value-added businesses declined significantly. The
decline was primarily due to high industry refined product inventory levels and
a dramatic and persistent run-up in crude oil prices throughout most of 1999.

The high inventory levels (primarily gasoline and distillates) resulted from
lower demand caused by two consecutive warm winters and a market structure that
provided incentives to build inventory in anticipation of higher future prices.
These factors had a particularly adverse impact on Sunoco due to the Company's
relatively high level of distillate production and its concentration of refin-
ing operations in the Northeast and Midwest where nearly all of the excess in-
ventory in the United States was held. A significant decline in crude oil
prices during 1998 led OPEC and other crude oil producers to reduce production
which ultimately resulted in crude oil prices more than doubling during 1999.
This had an adverse impact on Sunoco's margins as product prices were unable to
keep pace with the crude oil price increases.

Despite this poor margin environment, the Company believes margins should im-
prove during 2000 as a result of:

 .Lower than normal inventory levels for gasoline and distillates as the year
2000 begins;

 .Continued growth in demand for gasoline and distillate products;

 .Tightening of supply due to changes in reformulated gasoline product specifi-
cations;

 .An improvement in margins for certain petrochemical products; and

 .Expected flat to declining crude oil prices for the year 2000.

Notwithstanding the Company's expectation that margins should improve in the
future, given continued competitive market pressures and the highly volatile
and uncertain margin environment, Sunoco is committed to improving its results
by:

 .Increasing production levels and realizing other efficiencies at each of the
Company's manufacturing facilities;

 .Continuing to improve retail marketing through ongoing programs, including the
reimaging of Company outlets;

 .Prudently managing expenses and capital spending; and

 .Diversifying, upgrading and growing its asset portfolio through strategic ac-
quisitions and investments that are synergistic and accretive to earnings.

                                                                              10

Analysis of Earnings Profile of Sunoco Businesses
In 1999, Sunoco, Inc. and its subsidiaries earned $97 million, or $1.07 per
share of common stock on a diluted basis compared to $280 million, or $2.95 per
share in 1998 and $263 million, or $2.70 per share in 1997. Excluding the spe-
cial items shown separately in the Earnings Profile of Sunoco Businesses, Su-
noco earned $51 million in 1999, compared to $267 million in 1998 and $284 mil-
lion in 1997.

The $216 million decrease in earnings before special items in 1999 was primar-
ily due to significantly lower wholesale fuels margins in each of Sunoco's re-
fining centers. Also contributing to the decline were lower margins for lubri-
cants and retail gasoline, higher depreciation expense and the absence of $12
million of after-tax benefits related to the settlement of income tax issues
with the Internal Revenue Service during 1998. Partially offsetting these nega-
tive factors were higher sales volumes in Sunoco's Northeast refining and mar-
keting operations, higher non-gasoline income in Northeast Marketing and added
income from Sun Coke's Indiana Harbor cokemaking facility which began operation
in late March 1998. Lower chemical margins for aromatics and propylene were
offset by additional earnings from a cumene plant expansion completed in the
third quarter of 1998.

In 1998, the $17 million decrease in earnings before special items was primar-
ily due to significantly lower chemical margins, lower average retail and
wholesale gasoline margins and a greater amount of scheduled and unscheduled
downtime at the Company's refining facilities. Partially offsetting these nega-
tive factors were higher margins for lubricants, waxes and residual fuels, a
favorable foreign sweet crude oil market, and income from the Indiana Harbor
cokemaking facility and from the Philadelphia phenol facility acquired in mid-
1998. Also offsetting the decline were the favorable impact of the 1998 income
tax settlement discussed above and recognition in 1998 of $7 million of after-
tax earnings from the receipt of cash distributions from petroleum industry in-
surance consortia in which Sunoco participates.

Sun Northeast Refining operating results decreased $94 million in 1999 primar-
ily due to significantly lower realized margins for wholesale fuels. Partially
offsetting the lower margins was a 5.1 million barrel, or 3 percent, increase
in production levels. Overall production increased in 1999 despite a voluntary
cutback in production of low-value products in response to the low margin envi-
ronment. In addition, a week-long shutdown of a 200,000-barrels-per-day crude
unit at the Philadelphia refinery due to flooding caused by Hurricane Floyd ad-
versely impacted production. Production in 1998 was affected by a substantial
amount of scheduled and unscheduled downtime (see discussion below).

Sun Northeast Refining operating results decreased $10 million in 1998 due to
lower realized margins for wholesale fuels and a 4.3 million barrel decline in
gasoline and distillate production, partially offset by benefits from a favora-
ble foreign sweet crude oil market and a $10 million pretax reduction in oper-
ating expenses. The production decline was caused by the substantial amount of
scheduled and unscheduled refinery downtime during 1998. The most significant
of this downtime was at a 73,000-barrels-per-day catalytic cracking unit at the
Philadelphia refinery. It included a 29-day shutdown due to an emergency power
interruption by the local utility and related start-up problems and a subse-
quent scheduled six-week turnaround and modernization. With the completion of
this work in July 1998, all three of Sunoco's catalytic cracking units in the
Northeast had been modernized during the 1997-98 period. Scheduled maintenance
activity during 1998 also included a 23-day turnaround of the 200,000-barrels-
per-day crude unit at the Philadelphia refinery.

During 1998, Sunoco added $26 million after tax to an accrual it established on
December 31, 1996 for estimated losses expected to be realized from an off-take
agreement to purchase MTBE. This provision is reported as part of the Provision
for Write-Down of Assets and Other Matters shown separately in the Earnings
Profile of Sunoco Businesses (see Notes 4 and 14 to the consolidated financial
statements).

* Retail sales price less wholesale price. The retail sales price is the
  weighted average price received through the various branded marketing distri-
  bution channels.

Sunoco Northeast Marketing operating results declined $15 million in 1999 as a
4 percent increase in retail gasoline sales volumes and higher non-gasoline in-
come were more than offset by lower retail gasoline margins, which were down
approximately 1 cent per gallon versus 1998, and a $13 million pretax increase
in marketing and administrative expenses. The increase in expenses was largely
attributable to the higher sales volumes, higher depreciation expense and ex-
penditures supporting a retail site reimaging program.

The $4 million decline in Sunoco Northeast Marketing operating results in 1998
was primarily due to lower retail gasoline margins, which were down approxi-
mately 1 cent per gallon versus 1997. Partially offsetting this negative factor
was a 2 percent increase in retail gasoline sales volumes. Operating results
also benefited from a 4 percent improvement in average gasoline throughput at
the Company's direct sites and a 10 percent increase in average merchandise
sales per convenience store.

**  Sunoco Chemicals sold 13.5 thousand barrels daily of phenol and acetone in
    1998 subsequent to the June 30, 1998 acquisition of the Philadelphia phenol
    facility. The amount in the table for 1998 reflects the 2.49 million bar-
    rels sold during the second half of 1998 divided by 365 days.
*** Reflects reductions of 2.3 and 2.8 thousand barrels daily of cumene sales
    during 1999 and 1998, respectively. With the acquisition of the phenol fa-
    cility, all cumene production is now used in the production of phenol and
    acetone.

Sunoco Chemicals income decreased $3 million in 1999 primarily due to lower
margins for aromatics and polymer-grade propylene and higher expenses resulting
from unplanned maintenance activities. Partially offsetting these negative fac-
tors were additional earnings from a cumene plant expansion at the Philadelphia
refinery completed in July 1998. After completion of this project, the facility
produced cumene at an annualized rate of 1,012 million pounds during the fif-
teen-month period ended December 31, 1999, which

is well in excess of the 850 million pounds per year capacity that was origi-
nally projected for the expanded facility. In 1997, 573 million pounds of
cumene were produced.

Income from Sunoco Chemicals decreased $37 million in 1998 due to significantly
lower margins, particularly for polymer-grade propylene (down over 50 percent)
and cumene. Partially offsetting these negative factors was $11 million of af-
ter-tax income from operations at the Philadelphia phenol facility acquired
from AlliedSignal Inc. ("Allied") on June 30, 1998. The phenol facility cur-
rently has the capacity to produce annually more than one billion pounds of
phenol and 620 million pounds of acetone. In connection with this acquisition,
Sunoco Chemicals has entered into a long-term contract to supply Allied 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 pro-
duction costs.

The $46 million decline in Sun Lubricants operating results in 1999 was primar-
ily due to margin declines for all products manufactured by Sun Lubricants. The
base oil and specialty oil margin declines reflect the inability of wholesale
and retail lubricant prices to keep pace with the significant crude oil price
increases during 1999. Partially offsetting the margin declines were higher
base oil lubricant sales and production volumes and lower operating and admin-
istrative expenses as higher depreciation charges were more than offset by
lower cash expenses.

Sun Lubricants results improved $11 million in 1998 primarily due to higher
margins for lubricants, waxes and residual fuels and a $10 million pretax de-
cline in operating expenses. Production volumes and earnings during 1998 were
limited by a 59-day maintenance turnaround at the Puerto Rico refinery as well
as by a two-week shutdown of this

facility resulting from Hurricane Georges. Sun Lubricants operating results for
1998 exclude a $13 million tax benefit attributable to a change in tax election
concerning the Puerto Rico possession tax credit. The tax benefit is shown sep-
arately in the Earnings Profile of Sunoco Businesses.

Sunoco MidAmerica Marketing & Refining results decreased $37 million in 1999
primarily due to a significant decline in realized wholesale fuels margins.
Lower petrochemical margins and an increase in operating and administrative ex-
penses also contributed to the decline in earnings. Overall production in-
creased slightly in 1999 despite both planned and unplanned refinery mainte-
nance activities and voluntary production cuts due to the low margins. Produc-
tion in 1998 was also adversely impacted by a substantial amount of scheduled
and unscheduled downtime (see discussion below).

Sunoco MidAmerica Marketing & Refining results decreased $8 million in 1998
primarily due to lower wholesale gasoline and petrochemical margins. Partially
offsetting these negative factors were higher retail gasoline margins and 7
percent higher retail gasoline volumes. Production levels were essentially un-
changed compared to 1997 despite a one-month scheduled turnaround of one of the
Toledo refinery's crude oil units and a one-week shutdown of the refinery
caused by a regional electricity emergency.

Sunoco Logistics income decreased $1 million in 1999 as improved results in
Sunoco's Southwestern logistics operations were more than offset by higher op-
erating and administrative expenses. The improvement in Southwestern operations
was due in part to the income attributable to the crude transportation and mar-
keting operations acquired from Pride Companies, L.P. on October 5, 1999. In
1998, Sunoco Logistics income increased $1 million primarily due to improved
results from Sunoco's Southwestern logistics operations and higher throughput
in the Eastern product pipeline system.

Sun Coke income increased $3 million in 1999 due to an increase in income from
the Company's Indiana Harbor cokemaking facility in East Chicago, IN, which
commenced operations in late March 1998, and to a $7 million after-tax gain
from the divestment in February 1999 of Shamrock Coal Company ("Shamrock"), Sun
Coke's steam coal mining operation located in Kentucky. Earnings from Shamrock
were $5 million for the full year 1998. With this divestment, Sun Coke ceased
steam coal mining activities. Partially offsetting these positive factors were
lower earnings from the Jewell cokemaking operation in Vansant, VA, lower earn-
ings from Shamrock and the absence of a $2 million tax benefit recorded in 1998
related to the settlement of an income tax issue with the Internal Revenue
Service. In 1998, Sun Coke income increased $19 million primarily due to the
income contribution from the Indiana Harbor cokemaking facility.

Net Financing Expenses and Other--Net financing expenses and other increased
$23 million in 1999 after decreasing $11 million in 1998. The fluctuation dur-
ing the 1997-99 period was largely due to the recognition in 1998 of $7 million
of after-tax earnings from cash distributions received from petroleum industry
insurance consortia in which Sunoco participates and $10 million of after-tax
interest income related to income tax settlements. Lower capitalized interest
and higher interest expense due to a higher average debt level also contributed
to the increase during 1999.

Gain on Settlement of Insurance Litigation--In 1999 and 1998, Sunoco recognized
$47 and $38 million, respectively, of after-tax gains in connection with the
settlement of several insurance claims. The claims related to certain environ-
mental matters of Sunoco, including its predecessor companies and subsidiaries,
arising from ownership and operation of its businesses. (See Note 14 to the
consolidated financial statements.)

Benefit from Change in Tax Election--During 1998, Sunoco revoked its election
under the Internal Revenue Code concerning the Puerto Rico possession tax cred-
it. This change resulted in a $13 million tax benefit, which is attributable to
Sun Lubricants. (See Note 5 to the consolidated financial statements.)

Provision for Write-Down of Assets and Other Matters--During 1999, Sunoco re-
corded a $9 million after-tax charge in connection with the settlement of liti-
gation concerning the May 1998 redemption of the Company's depositary shares
and recorded an $8 million after-tax favorable adjustment to a market valuation
reserve established in 1998 for MTBE inventory of Sun Northeast Refining.

During 1998, Sunoco added $40 million ($26 million after tax) to the accrual it
established on December 31, 1996 for estimated losses expected to be realized
by Sun Northeast Refining from an off-take agreement to purchase MTBE. In addi-
tion, in 1998, Sunoco recorded an $8 million after-tax provision to write-down
the MTBE inventory of Sun Northeast Refining to market value, increased the es-
timated net realizable value of a previously written down asset held for sale
by Sun Northeast Refining by $8 million after tax, established a $7 million af-
ter-tax accrual for environmental remediation activities principally in Sunoco
Northeast Marketing and recorded a $5 million after-tax provision to write-off
certain assets primarily in Sunoco Chemicals.

In 1997, Sunoco established a $32 million accrual ($21 million after tax) for
approximately 320 involuntary employee terminations and related costs. The em-
ployee reductions were throughout Sunoco's six refining and marketing business
units and also included senior management and support staff.

For a further discussion of the provisions for write-down of assets and other
matters recorded during the 1997-99 period, see Notes 4, 14 and 15 to the con-
solidated financial statements.

Analysis of Consolidated Statements of Income

Revenues--Total revenues were $10.1 billion in 1999, $8.6 billion in 1998 and
$10.5 billion in 1997. The 17 percent increase in 1999 was primarily due to
higher refined product prices and sales volumes. In 1998, the 18 percent de-
crease was primarily due to lower refined product prices.

Costs and Expenses--Total pretax costs and expenses were $9.9 billion in 1999,
$8.2 billion in 1998 and $10.1 billion in 1997. The 21 percent increase in 1999
was primarily due to higher crude oil and refined product acquisition costs
largely as a result of the increase in crude oil prices. In 1998, the 19 per-
cent decrease was primarily due to lower crude oil and refined product acquisi-
tion costs largely as a result of lower crude oil prices.

Financial Condition

Capital Resources and Liquidity

Cash and Working Capital--At December 31, 1999, Sunoco had cash and cash equiv-
alents of $87 million compared to $38 million at December 31, 1998 and had a
working capital deficit of $310 million compared to $204 million at December
31, 1998. Sunoco's working capital position is considerably stronger than indi-
cated because of the relatively low historical costs assigned under the LIFO
method of accounting for most of the inventories reflected in the consolidated
balance sheets. The current replacement cost of all such inventories exceeds
their carrying value at December 31, 1999 by $763 million. Inventories valued
at LIFO, which consist of crude oil and refined products, are readily market-
able at their current replacement values. Management believes that the current
levels of Sunoco's cash and working capital are adequate to support Sunoco's
ongoing operations.

Cash Flows and Financial Capacity--In 1999, Sunoco's net cash provided by oper-
ating activities ("cash generation") was $499 million compared to $352 million
in 1998 and $452 million in 1997. The $147 million increase in cash generation
in 1999 was largely due to a decrease in working capital uses pertaining to op-
erating activities and the receipt of proceeds from settlement of several in-
surance claims, partially offset by a decline in income before special items
and lower deferred income tax expense. The $100 million decrease in cash gener-
ation in 1998 was largely due to a decline in income before special items and a
reduction in noncash charges.

Divestment activities have also been a source of cash. During the 1997-99 peri-
od, proceeds from divestments totalled $392 million.

In early 1998, Sunoco transferred an interest in its Indiana Harbor cokemaking
operation in East Chicago, IN, to a third party in exchange for $200 million in
cash. The investor is entitled to 95 percent of the cash flows and tax benefits
from this cokemaking operation until certain cumulative return targets have
been met. After this preferential return period, which is expected to end in
2002, the third party will be entitled to a variable minority interest in the
cash flows and tax benefits from the Indiana Harbor cokemaking operation rang-
ing from 5 to 23 percent. Sunoco did not recognize any gain or loss on this
transaction.

Management believes that future cash generation will be sufficient to satisfy
Sunoco's capital requirements and to pay the current level of cash dividends on
Sunoco's common stock. However, from time to time, the Company's short-term
cash requirements may exceed its cash generation due to various factors includ-
ing volatility in crude oil and refined product markets and increases in capi-
tal spending and working capital levels. During those periods, the Company may
supplement its cash generation with proceeds from financing activities.

The Company has a $500 million revolving credit agreement ("Agreement") with
commercial banks that provides access to short-term financing through September
2002. The Company can borrow directly from the participating banks under this
Agreement or use it to support the issuance of commercial paper. (See Note 10
to the consolidated financial statements.)

Sunoco's ratio of debt (net of available cash) to total capital was 38.5 per-
cent at December 31, 1999 compared to 39.1 percent at December 31, 1998. Man-
agement believes there is sufficient borrowing capacity available to pursue
strategic investment opportunities as they arise. No commitments have been made
with respect to any investment opportunity which would require the use of a
significant portion of Sunoco's unused financial capacity. In addition, the
Company has the option of issuing additional common or preference stock as a
means of increasing its equity base; however, there are no current plans to do
so.

*  Excludes $157 million purchase of the Philadelphia phenol facility.
** Excludes $36 million purchase of the crude oil transportation and marketing
   operations of Pride Companies, L.P.

In 1999, in addition to the $36 million acquisition of the Pride crude oil
transportation and marketing operations, major capital outlays included: $29
million to complete the turnaround and the first phase of an oxidizer unit re-
placement project at the Philadelphia phenol facility acquired in 1998, $68
million primarily to upgrade or acquire additional Sunoco(R) retail marketing
locations in the Northeast and $35 million related to an ongoing reimaging pro-
gram at the Company's retail service station network. As part of the reimaging
program, the Company's Sunoco(R) logo has been updated and its retail outlet
image has been redesigned to provide a more contemporary appearance.

In 1998, in addition to the $157 million acquisition of the Philadelphia phenol
facility and the $12 million of capital outlays at this facility subsequent to
the acquisition, major capital outlays included: $58 million to complete the
construction of the Indiana Harbor cokemaking facility that commenced opera-
tions in the first quarter of 1998; $30 million to complete the expansion of
the Philadelphia refinery's cumene production facilities; $94 million for the
scheduled turnaround and modernization of numerous units throughout the
Company's refinery network; and $44 million to upgrade or acquire Sunoco(R) re-
tail marketing locations in the Northeast.

<PAGE>


In 1997, major capital expenditures included: $118 million for the then ongoing
construction of the Indiana Harbor cokemaking facility; $25 million to begin
the expansion of the Philadelphia refinery's cumene production capacity; $17
million for the scheduled turnaround of various units at the Philadelphia re-
finery including a catcracker, a crude unit and a gasoline reformer; and $46
million largely for service station modernization activities in the Northeast.

The 2000 capital expenditure plan is comprised of $235 million for base infra-
structure and legally required spending, $91 million for turnarounds at the
Company's Philadelphia, Marcus Hook and Toledo refineries and $118 million for
growth projects. The growth projects include expenditures to improve refinery
efficiency, grow Sunoco's retail marketing network, increase chemicals produc-
tion and expand certain logistics assets.

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:

* Capital expenditures for pollution abatement are expected to approximate $25
  and $35 million in 2000 and 2001, respectively.

The Clean Air Act establishes stringent criteria for regulating air toxics at
operating facilities by mandating major reductions in allowable emissions and
establishing a more comprehensive list of substances deemed to be air toxics.
The Clean Air Act also requires refiners to market cleaner-burning gasoline
that reduces emissions of certain toxic and conventional pollutants. The Com-
pany has implemented the first two phases of the reformulated gasoline regula-
tions which require an increase in the minimum quantity of oxygen for certain
non-attainment areas, a reduction in benzene content, and a reduction in sum-
mertime Reid Vapor Pressure ("RVP"). Sunoco expects to implement the more
stringent final phase of these regulations in the spring of 2000.

Pursuant to the Clean Air Act, in December 1999 the U.S. Environmental Protec-
tion Agency ("EPA") issued a final rule to require more stringent emissions
standards ("Tier 2 Standards") for new passenger cars and light duty trucks.
The final rule mandates significant reductions in the sulfur levels in reformu-
lated and conventional gasoline commencing in 2004. The rule includes a banking
and trading credit system, which could provide refiners compliance flexibility
until 2006. Sunoco currently has gasoline sulfur levels which are below the in-
dustry average and idle assets which may be used to help meet this new require-
ment. Analysis of the rule to determine its impact and to identify compliance
alternatives by the required dates is ongoing. The rule could have a signifi-
cant impact on Sunoco and its operations, primarily with respect to the capital
and operating expenditures at the Philadelphia, Marcus Hook and Toledo refin-
eries. The capital spending is likely to begin in early 2003 while the higher
operating costs will be incurred when production of the low-sulfur gasoline
commences. The ultimate impact of the rule cannot be determined at this time,
and may be affected by such factors as technology selection, the effectiveness
of the banking and trading credit system, timing uncertainties created by per-
mitting requirements and construction schedules and any effect on prices cre-
ated by changes in the level of gasoline production.

                                                                              20

In order to obtain a secure supply of oxygenates, Sunoco entered into an off-
take agreement with Belvieu Environmental Fuels ("BEF"), a joint venture in
which Sunoco is a one-third partner, whereby Sunoco agreed to purchase all of
the MTBE from BEF's production facility. At December 31, 1999, the Company had
a $55 million investment in this operation. In 1998 and 1996, Sunoco recorded
pretax provisions amounting to $40 and $130 million, respectively, for esti-
mated purchase commitment losses expected to be realized with respect to the
off-take agreement. During 1999, 1998 and 1997, actual losses attributable to
this agreement amounting to $39, $47 and $65 million, respectively, were
charged against the loss accrual. The accrual has a remaining balance of $19
million as of December 31, 1999. (See Note 14 to the consolidated financial
statements.)

In November 1998, the EPA convened an advisory Panel on Oxygenate Use in Gaso-
line (the "Panel"). The purpose of the Panel was to review public health and
environmental issues that have been raised by the use of MTBE in gasoline, and
specifically by the discovery of MTBE in water supplies. The Panel made its
recommendations to the EPA on July 27, 1999. The recommendations call for the
improved protection of drinking water from MTBE contamination, a substantial
reduction in the use of MTBE, and action by Congress to remove the oxygenate
requirements for reformulated gasoline under the Clean Air Act. State and fed-
eral environmental agencies could implement the majority of the recommenda-
tions; however, some would require Congressional legislative action. While the
Panel recommended that certain public and private funding options be explored
for the clean up of contaminated sites, it made no specific recommendations
concerning such funding options. However, private parties are seeking clean-up
remedies primarily from East and West Coast gasoline marketers, including Suno-
co. California has acted to ban MTBE use by December 31, 2002. In connection
with the MTBE ban, California has requested a waiver from the EPA of its oxy-
genate requirements. Other states are also reviewing the use of MTBE in gaso-
line. MTBE is the primary oxygenate used by Sunoco and throughout the industry
to meet the reformulated gasoline requirements under the Clean Air Act. While
phase-outs or restrictions on the use of MTBE or any required clean up of MTBE
could have a significant impact on Sunoco and its results of operations, the
ultimate impact cannot be determined at this time.

The Comprehensive Environmental Response Compensation and Liability Act
("CERCLA") and the Solid Waste Disposal Act as amended by the Resource Conser-
vation and Recovery Act ("RCRA"), and related federal and state laws subject
Sunoco to the potential obligation to remove or mitigate the environmental ef-
fects 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, 1999, Sunoco had been named as a PRP at 52 sites identified or
potentially identifiable as "Superfund" sites under CERCLA. Sunoco has reviewed
the nature and extent of its involvement at each site and other relevant cir-
cumstances and, based upon the other parties involved or Sunoco's negligible
participation therein, believes that its potential liability associated with
such sites will not be significant.

Under various environmental laws, including RCRA, Sunoco has initiated correc-
tive remedial action at its facilities, formerly-owned facilities and third-
party sites and could be required to undertake similar actions at various other
sites. The cost of such remedial actions could be significant but is expected
to be incurred over an extended period of time.

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 liabili-
ties and charges against income related to these activities, see Note 14 to the
consolidated financial statements.

On October 4, 1996, Sunoco filed a complaint in Los Angeles County Superior
Court, Jalisco Corporation, Inc., et al. v. Argonaut Insurance Company, et al.
(Case No. BC 158441), naming more than 45 insurance companies as defendants and
seeking recovery under numerous insurance policies for certain environmental
matters of Sunoco, including its predecessor companies and subsidiaries, aris-
ing from the ownership and operation of its businesses. In 1999 and 1998, the
Company entered into several settlements which resolved most of these claims.
As a result, the Company received net cash proceeds totalling $4 million in
1998, $96 million in 1999 and $28 million in early 2000. Pretax gains of $73
million ($47 million after tax) and $58 million ($38 million after tax) were
recognized in 1999 and 1998, respectively, in connection with these settle-
ments.

Total future costs for environmental remediation activities will depend upon,
among other things, the identification of any additional sites, the determina-
tion 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 var-
ious 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 overall expenditures for the matters discussed
above are likely to be significant but are expected to be incurred over an ex-
tended period of time and to be funded from Sunoco's net cash provided by oper-
ating activities. Although potentially significant with respect to results of
operations or cash flows for any one year, management believes that such costs
will not have a material impact on Sunoco's consolidated financial position or,
over an extended period of time, on Sunoco's cash flows or liquidity.

Year 2000 Information Processing
During the 1997-99 period, Sunoco assessed, remediated or replaced, tested and
implemented computer systems and applications in order that they would be able
to operate and properly process information dated after December 31, 1999. As a
result of these efforts, the Company has not experienced any Year 2000 failures
of its key computer systems and applications. Likewise, the Company's key cus-
tomers and suppliers have been able to continue to meet their obligations to
the Company.

The cost to Sunoco during the 1997-99 period of achieving Year 2000 compliant
systems totaled $37 million. Such amount consisted of $21 million of expense
incurred remediating and testing existing software and hardware and $16 million
of capital expenditures to replace two key non-compliant systems with newly
purchased systems that, in addition to being compliant, provide enhanced busi-
ness functionality.

Although unlikely, the possibility still exists that interruptions to Company
and/or key customer and supplier operations or business activities could occur
as a result of lingering Year 2000 Issues. Such interruptions, if they were to
occur, could have a material adverse impact on Sunoco's consolidated results of
operations or financial condition.

Derivative Instruments
Sunoco uses futures and forward contracts to achieve ratable pricing of its
crude oil purchases and to convert certain refined product sales from fixed to
floating price. In addition, price collars, swaps and option contracts are used
to lock in a portion of the Company's electricity and natural gas costs. Sunoco
also uses swaps, price collars and other contracts from time to time to hedge
against significant increases in crude oil prices and to lock in what Sunoco
considers to be acceptable margins for various refined products. At December
31, 1999, margins for approximately 14 million barrels (6 percent of the
Company's expected 2000 wholesale fuels sales) had been locked in.

                                                                              22

Sunoco is at risk for possible changes in the market value of all of its deriv-
ative contracts; however, such risk would be mitigated by price changes in the
underlying hedged transactions. At December 31, 1999, Sunoco had a net deferred
gain of $13 million on its outstanding derivative contracts. The potential de-
crease in this gain from a hypothetical 10 percent adverse change in the year-
end market prices of commodities that were being hedged by derivative contracts
at December 31, 1999 was estimated to be $10 million. This hypothetical de-
crease in the gain was estimated by multiplying the difference between the hy-
pothetical and the actual year-end market prices of the underlying commodities
by the contract volume amounts.

Sunoco also is exposed to credit risk in the event of nonperformance by
counterparties. Management believes this risk is negligible as its
counterparties are either regulated by exchanges or are major international fi-
nancial institutions with high credit ratings. (See Note 17 to the consolidated
financial statements.)

In June 1998, Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities" ("SFAS No. 133") was issued.
SFAS No. 133, which Sunoco expects to adopt effective January 1, 2001 when
adoption is mandatory, changes the method of accounting for derivative instru-
ments. The Company has not yet determined the impact that the new standard will
have on its results of operations and financial position. For a further discus-
sion concerning SFAS No. 133, see Note 1 to the consolidated financial state-
ments.

Cash Dividends and Share Redemption and Repurchases
The Company has paid cash dividends on a regular quarterly basis since 1904.
During the 1997-99 period, the quarterly cash dividend paid on common stock
amounted to $.25 per share ($1.00 per year). The Company expects to continue to
sustain the quarterly common stock cash dividend at its current level. Cash
dividends paid on depositary shares totalled $1.80 per share in 1997 and $.8258
per share in 1998 prior to their redemption (see below).

On May 28, 1998, the Company redeemed all of its 24,067,520 then outstanding
depositary shares. Each depositary share represented ownership of one-half
share of the Company's Series A cumulative preference stock. Under the terms of
redemption, established when the depositary shares were issued, each depositary
share was redeemed in exchange for 0.949837 share of Sunoco's common stock plus
accrued and unpaid dividends of $.3758. The depositary-to-common stock exchange
ratio represented the call price of $40 per depositary share payable in Sunoco
common stock valued at $42.1125 per common share--the average of the closing
prices for Sunoco common stock on the New York Stock Exchange, as reported on
the consolidated tape, for the five consecutive trading days from April 20 to
April 24, 1998, inclusive. At the exchange ratio of 0.949837 share of common
stock for each depositary share, 22,859,633 shares of Sunoco common stock held
in treasury were reissued. In connection with this redemption, a lawsuit was
filed alleging that Sunoco incorrectly calculated the exchange ratio and should
have issued an additional 1.36 million shares of Sunoco common stock. While the
Company believes the exchange ratio was correctly calculated, in the fourth
quarter of 1999 it agreed to settle the lawsuit, subject to court approval. Ac-
cordingly, a $14 million charge ($9 million after tax) was recorded in 1999 in
connection with the settlement. This charge is reported as part of the Provi-
sion for Write-Down of Assets and Other Matters shown separately in the Earn-
ings Profile of Sunoco Businesses.

During the 1997-99 period, the Company repurchased 8,260,950 shares of its com-
mon stock and 853,580 of its depositary shares for $335 million. At December
31, 1999, the Company had a remaining authorization from its Board of Directors
to purchase up to $136 million of Company stock in the open market or through
privately negotiated transactions from time to time depending on prevailing
market conditions.

Forward-Looking Statements
Statements and financial discussion and analysis contained in the Management's
Discussion and Analysis that are not historical facts are forward-looking
statements made pursuant to the safe harbor provisions of the Private Securi-
ties Litigation Reform Act of 1995. Such statements generally will be accompa-
nied by words such as "anticipate," "believe," "estimate," "expect," "fore-
cast," "intend," "possible," "potential," "predict," "project," or other simi-
lar words that convey the uncertainty of future events or outcomes. Although
Sunoco believes these forward-looking statements are reasonable, they are based
upon a number of assumptions concerning future conditions, any or all of which
may ultimately prove to be inaccurate. Forward-looking statements involve a
number of risks and uncertainties. Important factors that could cause actual
results to differ materially from the forward-looking statements include, with-
out limitation:

 .Changes in industry-wide refining margins;

 .Variation in commodity prices and crude oil supply;

 .Volatility in the marketplace which may affect market supply and demand for
Sunoco's products;

 .Increased competition;

 .Changes in the reliability and efficiency of the Company's operating facili-
ties;

 .Changes in the level of operating expenses and hazards common to operating fa-
cilities (including equipment malfunction, explosions, fires, oil spills, and
the effects of severe weather conditions);

 .Changes in the expected level of environmental remediation spending;

 .Delays related to work on facilities and the issuance of applicable permits;

 .Changes in product specifications;

 .Availability and pricing of oxygenates such as MTBE;

 .Phase-outs or restrictions on the use of MTBE;

 .Political and economic conditions in international markets in which the Com-
pany operates;

 .Changes in the availability of debt and equity financing resulting in in-
creased costs or reduced liquidity;

 .Risks related to labor relations;

 .Nonperformance by major customers;

 .General economic, financial and business conditions which could affect
Sunoco's financial condition and results of operations;

 .Changes in applicable statutes and government regulations or their interpreta-
tions;

 .Claims of the Company's noncompliance with statutory and regulatory require-
ments;

                                                                              24
<PAGE>


 .Changes in the status of litigation to which the Company is a party; and

 .Potential effects of Year 2000 computer issues.

The factors identified above are believed to be important factors (but not nec-
essarily all of the important factors) that could cause actual results to dif-
fer materially from those expressed in any forward-looking statement made by
Sunoco. Unpredictable or unknown factors not discussed herein could also have
material adverse effects on forward-looking statements. All forward-looking
statements included in this Annual Report to Shareholders are expressly quali-
fied in their entirety by the foregoing cautionary statements. The Company un-
dertakes no obligation to update publicly any forward-looking statement (or its
associated cautionary language) whether as a result of new information or fu-
ture events.

Notes to Consolidated Financial Statements         Sunoco, Inc. and Subsidiaries

1. Summary of Significant Accounting Policies

Principles of Consolidation
The consolidated financial statements of Sunoco, Inc. and subsidiaries
(collectively, "Sunoco" or the "Company") contain the accounts of all
operations that are controlled (generally more than 50 percent owned).
Affiliated companies over which the Company has the ability to exercise
significant influence but that are not controlled (generally 20 to 50 percent
owned) are accounted for by the equity method.

Use of Estimates
Certain amounts included in the accompanying consolidated financial statements
and related footnotes reflect the use of estimates based on assumptions made by
management. Actual amounts could differ from these estimates.

Cash Equivalents
Sunoco considers all highly liquid investments with a remaining maturity of
three months or less at the time of purchase to be cash equivalents. These cash
equivalents consist principally of time deposits and certificates of deposit.

Inventories
Inventories are valued at the lower of cost or market. The cost of crude oil
and refined product inventories is determined using the last-in, first-out
method ("LIFO"). The cost of materials, supplies and other inventories is de-
termined using principally the average cost method.

Depreciation and Retirements
Plants and equipment are generally depreciated on a straight-line basis over
their estimated useful lives. Gains and losses on the disposals of fixed assets
are generally reflected in income.

Environmental Remediation
Sunoco accrues environmental remediation costs for work at identified sites
where an assessment has indicated that cleanup costs are probable and reasona-
bly estimable. Such accruals are undiscounted and are based on currently avail-
able information, estimated timing of remedial actions and related inflation
assumptions, existing technology and presently enacted laws and regulations.

Maintenance Shutdowns
Maintenance and repair costs in excess of $500 thousand incurred in connection
with major maintenance shutdowns are capitalized when incurred and amortized
over the period benefited by the maintenance activities.

Derivative Instruments
Sunoco uses swaps, options, futures, forwards and other off-balance sheet com-
modity-based financial and nonfinancial derivative instruments to hedge its ex-
posure to crude oil, refined product, electricity and natural gas price vola-
tility. Such contracts, which effectively meet the Company's risk reduction and
correlation criteria, are accounted for using hedge accounting as prescribed
principally by Statement of Financial Accounting Standards No. 80, "Accounting
for Futures Contracts" ("existing hedge accounting"). Effectiveness is measured
based upon the correlation between the gains and losses on the derivative con-
tracts and the corresponding offsetting changes in the market value of the
items being hedged. Under existing hedge accounting, gains or losses on deriva-
tive contracts (including positions which have been closed) are deferred and
recognized in cost of products sold and operating expenses in the same periods
as the items being hedged. In the event an open derivative contract were to be-
come ineffective as a hedge or if an anticipated transaction being hedged were
no longer likely to occur, any related unrealized derivative gain or loss would
be recognized in net income at such time. The cash flows from hedge contracts
are included in operating activities in the consolidated statements of cash
flows. Sunoco does not hold or issue derivative instruments for trading purpos-
es.

In June 1998, Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities" ("SFAS No. 133") was issued.
Sunoco expects to adopt SFAS No. 133 effective January 1, 2001 when adoption is
mandatory. It will require the Company to recognize all derivative contracts on
the balance sheet at their fair value. Changes in fair value of derivative con-
tracts that are not hedges will be recognized in net income as they occur. If
the derivative contracts are hedges, depending on their nature, changes in
their fair values will either be offset in net income against the changes in
the fair values of the items being hedged or reflected initially as a separate
component of shareholders' equity and subsequently recognized in net income
when the hedged items are recognized in net income. The ineffective portions of
changes in the fair values of derivative contracts designated as hedges will be
immediately recognized in net income. The Company has not yet determined the
impact that SFAS No. 133 will have on its results of operations or its finan-
cial position.

Stock-Based Compensation
The Company follows the method of accounting for employee stock compensation
plans prescribed by Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" ("APB No. 25").

Reclassifications
Certain amounts in the prior years' financial statements have been reclassified
to conform to the current year presentation.

2. Settlement of Income Tax Disputes

In 1998, Sunoco settled certain income tax disputes with the Internal Revenue
Service related to deductions claimed in prior years. These settlements, which
include the recognition of $15 million of interest income, increased 1998 net
income by $12 million.

During 1999, Sunoco recorded a charge in connection with the settlement of lit-
igation concerning the May 1998 redemption of the Company's preference stock
(Note 15) and recorded a favorable adjustment to a market valuation reserve for
MTBE inventory established in 1998.

During 1998, Sunoco added to the accrual it established on December 31, 1996
for estimated losses expected to be realized from an off-take agreement to pur-
chase MTBE (Note 14). In addition, during 1998, Sunoco established an accrual
for environmental remediation activities, increased the estimated net realiz-
able value of a previously written down asset held for sale and recorded provi-
sions to write-down its MTBE inventory to market value and to write-off certain
assets primarily in its refining and marketing business.

During the first quarter of 1997, Sunoco established an accrual for approxi-
mately 320 involuntary employee terminations and related costs. The employee
reductions were throughout the organization and included senior management,
support staff and operations personnel. As of December 31, 1999, all of this
accrual has been paid.

* During 1998, Sunoco revoked its election under the Internal Revenue Code con-
  cerning the Puerto Rico possession tax credit. The $13 million tax benefit
  resulted primarily from recognition of additional deferred tax benefits asso-
  ciated with a write-down of assets recorded in 1996 in connection with a
  project to reconfigure the Company's Puerto Rico refinery.

10. Short-Term Borrowings and Credit Facilities

The Company has a $500 million revolving credit agreement ("Agreement") with
commercial banks that provides access to short-term financing through September
2002 bearing interest based on selected reference rates. The Company can borrow
directly from the participating banks under this Agreement or use it to support
the issuance of commercial paper. The Agreement is subject to commitment fees,
the amounts of which are not material. Under the terms of the Agreement, Sunoco
is required to maintain consolidated net worth of at least $1.0 billion. At De-
cember 31, 1999, the Company's consolidated net worth was $1.5 billion. The
Agreement also requires that Sunoco's ratio of debt to capital, as those terms
are defined in the Agreement, not exceed .55 to 1. At December 31, 1999, this
ratio was .41 to 1. The following table sets forth amounts outstanding related
to the above short-term borrowing arrangements:

12. Retirement Benefit Plans

Defined Benefit Pension Plans and Postretirement Health Care and Life Insurance
Plans
Sunoco has noncontributory defined benefit pension plans ("defined benefit
plans") which provide retirement benefits for the majority of its employees.
Sunoco also has plans which provide health care and life insurance benefits for
substantially all of its retirees ("postretirement benefit plans"). The
postretirement benefit plans are unfunded and the costs are shared by Sunoco
and its retirees.

Certain of the Company's defined benefit plans have accumulated benefit obliga-
tions in excess of the fair value of plan assets. The total projected benefit
obligations, accumulated benefit obligations and fair value of plan assets of
such plans were $125, $121 and $-- million, respectively, as of December 31,
1999 and $255, $234 and $106 million, respectively, as of December 31, 1998.

The following weighted average assumptions were used during 1999 and 1998 in
accounting for the plans:

The health care cost trend assumptions used at December 31, 1999 and 1998 to
compute the APBO for the postretirement benefit plans were 6.3 and 6.8 percent,
respectively, which are assumed to decline gradually to 5.5 percent in 2001 and
to remain at that level thereafter.

A one-percentage point change each year in assumed health care cost trend rates
would have the following effects at December 31, 1999:

Defined Contribution Pension Plans
Sunoco has defined contribution pension plans which provide retirement benefits
for most of its employees. Sunoco's contributions, which are principally based
on a percentage of employees' annual base compensation and are charged against
income as incurred, amounted to $16, $18 and $17 million in 1999, 1998 and
1997, respectively.

Sunoco's principal defined contribution plan is SunCAP. Sunoco matches 100 per-
cent of employee contributions to this plan up to 5 percent of an employee's
base compensation. SunCAP is a combined profit sharing and employee stock own-
ership plan which contains a provision designed to permit SunCAP, only upon ap-
proval by the Company's Board of Directors, to borrow in order to purchase
shares of Company common stock. As of December 31, 1999, no such borrowings had
been approved.

13. Transferred Interests in Cokemaking Operations

In 1998, Sunoco transferred an interest in its Indiana Harbor cokemaking opera-
tion in East Chicago, IN, to a third party for $200 million in cash. In 1995,
Sunoco transferred an interest in its Jewell cokemaking
operation in Vansant, VA, to another third party for $95 million in cash. The
investors in each operation are entitled to 95 percent 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 2002 and 2000, respectively, the third parties will be
entitled to variable minority interests in the cash flows and tax benefits from
the respective operations ranging from 5 to 25 percent. Sunoco did not recog-
nize any gain or loss on these transactions. The outstanding balance attribut-
able to the transferred interests in these operations totalled $175 and $226
million at December 31, 1999 and 1998, respectively, and is reflected in other
deferred credits and liabilities in the consolidated balance sheets.

14. Commitments and Contingent Liabilities

Sunoco, as lessee, has noncancelable operating leases for marine transportation
time charters and for service stations, office space and other property and
equipment. Total rental expense for such leases for the years 1999, 1998 and
1997 amounted to $115, $118 and $107 million, respectively. Approximately 8
percent of total rental expense was recovered through related sublease rental
income during 1999.

The aggregate amount of future minimum annual rentals applicable to noncancel-
able operating leases are as follows (in millions of dollars):

A wholly owned subsidiary of the Company is a one-third partner in Belvieu En-
vironmental Fuels ("BEF"), a joint venture formed for the purpose of construct-
ing, owning and operating a methyl tertiary butyl ether ("MTBE") production fa-
cility in Mont Belvieu, Texas. At December 31, 1999, the Company had a $55 mil-
lion investment in this operation.

                                       35

In order to obtain a secure supply of oxygenates for the manufacture of refor-
mulated gasoline, Sunoco entered into an off-take agreement with BEF whereby
Sunoco agreed to purchase all of the MTBE production from the plant. From May
1997 through May 2000, for the first 14,000 barrels daily of production, Sunoco
agreed to pay BEF a price based on then-existing MTBE prices in the contract
market (the "contract market price"). Sunoco also agreed to pay BEF the current
spot market price for production above 14,000 barrels daily. In addition, the
price to be paid by Sunoco for the first 12,600 barrels daily of MTBE produc-
tion from May 1997 through May 2000, at a minimum, generally will equal the sum
of BEF's annual raw material and cash operating costs associated with that pro-
duction plus BEF's debt service payments (collectively, the "minimum price") if
the minimum price per gallon exceeds the contract market price. Sunoco has been
paying the minimum price under this agreement since May 1997. After May 2000,
Sunoco and BEF will negotiate a new price for the last four years of the agree-
ment based upon the market conditions existing at that time.

Sunoco's total MTBE purchases under this agreement were $192, $182 and $235
million during 1999, 1998 and 1997, respectively. During the fourth quarter of
1996, spot market prices for MTBE were less than the prices paid by Sunoco un-
der the off-take agreement with BEF. At that time, the Company expected this
adverse relationship to continue into the future. Accordingly, a $130 million
accrual ($85 million after tax) was established at December 31, 1996 for the
estimated purchase commitment loss expected to be realized with respect to this
agreement.

The $130 million loss accrual was based primarily on the Company's marketplace
assumptions concerning the worldwide supply and demand for MTBE through May
2000. At December 31, 1996, the Company believed that MTBE demand would in-
crease in 1999 largely as a result of various jurisdictions electing to volun-
tarily comply with (or opt into) the reformulated gasoline requirements of the
Clean Air Act by the end of 1998. At December 31, 1998, the number of "opt ins"
was lower than what the Company had originally anticipated and certain other
jurisdictions were considering "opting out" of the voluntary reformulated fuel
requirements. As a result of these and other market factors, management be-
lieved that MTBE demand would not increase as previously anticipated. Accord-
ingly, an additional $40 million ($26 million after tax) was added to the ac-
crual in December 1998 for incremental losses expected to be realized with re-
spect to this agreement. During 1999, 1998 and 1997, actual MTBE purchase costs
in excess of spot market prices totalling $39, $47 and $65 million, respective-
ly, were charged against the accrual. The accrual has a remaining balance of
$19 million as of December 31, 1999.

In November 1998, the EPA convened an advisory Panel on Oxygenate Use in Gaso-
line (the "Panel"). The purpose of the Panel was to review public health and
environmental issues that have been raised by the use of MTBE in gasoline, and
specifically by the discovery of MTBE in water supplies. The Panel made its
recommendations to the EPA on July 27, 1999. The recommendations call for the
improved protection of drinking water from MTBE contamination, a substantial
reduction in the use of MTBE, and action by Congress to remove the oxygenate
requirements for reformulated gasoline under the Clean Air Act. State and fed-
eral environmental agencies could implement the majority of the recommenda-
tions; however, some would require Congressional legislative action. While the
Panel recommended that certain public and private funding options be explored
for the clean up of contaminated sites, it made no specific recommendations
concerning such funding options. However, private parties are seeking clean-up
remedies primarily from East and West Coast gasoline marketers, including Suno-
co. California has acted to ban MTBE use by December 31, 2002. In connection
with the MTBE ban, California has requested a waiver from the EPA of its oxy-
genate requirements. Other states are also reviewing the use of MTBE in gaso-
line. MTBE is the primary oxygenate used by Sunoco and throughout the industry
to meet the reformulated gasoline requirements under the Clean Air Act. While
phase-outs or restrictions on the use of MTBE or any required clean up of MTBE
could have a significant impact on Sunoco and its results of operations, the
ultimate impact cannot be determined at this time.

Sunoco is a party under agreements which provide for future payments to secure
wastewater treatment services at its Toledo refinery and coal handling services
at its Indiana Harbor cokemaking facility. The fixed and determinable amounts
of the obligations under these agreements are as follows (in millions of dol-
lars):

Payments under these agreements, including variable components, commenced in
mid-1998 and totalled $16 and $8 million in 1999 and 1998, respectively.

Sunoco is contingently liable under various arrangements which guarantee debt
of affiliated companies and others aggregating approximately $26 million at De-
cember 31, 1999 and maturing at various dates through 2014.

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 result in liabilities and loss con-
tingencies for remediation at Sunoco's facilities and at third-party or former-
ly-owned sites. The accrued liability for environmental remediation is classi-
fied in the consolidated balance sheets as follows:

</TABLE>

Pretax charges against income for environmental remediation totalled $11, $13
and $6 million in 1999, 1998 and 1997, respectively. Claims for recovery of en-
vironmental liabilities that are probable of realization totalled $2 million at
December 31, 1999 and are included in deferred charges and other assets in the
consolidated balance sheets.

On October 4, 1996, Sunoco filed a complaint in Los Angeles County Superior
Court, Jalisco Corporation, Inc., et al. v. Argonaut Insurance Company, et al.
(Case No. BC 158441), naming more than 45 insurance companies as defendants and
seeking recovery under numerous insurance policies for certain environmental
matters of Sunoco, including its predecessor companies and subsidiaries, aris-
ing from the ownership and operation of its businesses. In 1999 and 1998, the
Company entered into several settlements which resolved most of these claims.
As a result, the Company received net cash proceeds totalling $4 million in
1998, $96 million in 1999 and $28 million in early 2000. Pretax gains of $73
million ($47 million after tax) and $58 million ($38 million after tax) were
recognized in other income in 1999 and 1998, respectively, in connection with
these settlements.

Total future costs for environmental remediation activities will depend upon,
among other things, the identification of any additional sites, the determina-
tion 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 var-
ious 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 levels and financial
viability of other parties.

Many other legal and administrative proceedings are pending against Sunoco. The
ultimate outcome of these proceedings and the matters discussed above cannot be
ascertained at this time; however, it is reasonably possible that some of them
could be resolved unfavorably to Sunoco. Management believes that any expendi-
tures attributable to these matters will be incurred over an extended period of
time and will be funded from Sunoco's net cash flows from operating activities.
Although the ultimate impact of these matters could have a significant impact
on results of operations for any one year, management of Sunoco believes that
any additional liabilities which may arise pertaining to such matters would not
be material in relation to the consolidated financial position of Sunoco at De-
cember 31, 1999.

15. Shareholders' Equity

Each share of Company common stock is entitled to one full vote. The $10 mil-
lion of outstanding 6 3/4 percent debentures are convertible into shares of Su-
noco common stock at any time prior to maturity at a conversion price of $40.81
per share and are redeemable at the option of the Company. At December 31,
1999, there were 242,981 shares of common stock reserved for this potential
conversion (Note 11).

On May 28, 1998, the Company redeemed all of its 12,033,760 then outstanding
shares of preference stock. Each share of preference stock was evidenced by two
depositary shares. Under the terms of redemption, established when the shares
of preference stock were issued, each preference share was redeemed in exchange
for 1.899674 shares of Sunoco's common stock plus accrued and unpaid dividends
of $.7516. The preference-to-common stock exchange ratio represented the call
price of $80 per preference share payable in Sunoco common stock valued at
$42.1125 per common share--the average of the closing prices for Sunoco common
stock on the New York Stock Exchange, as reported on the consolidated tape, for
the five consecutive trading days from April 20 to April 24, 1998, inclusive.
At the exchange ratio of 1.899674 shares of common stock for each share

                                       37
<PAGE>

of preference stock, 22,859,633 shares of Sunoco common stock held in treasury
were reissued. In connection with this redemption, a lawsuit was filed alleging
that Sunoco incorrectly calculated the exchange ratio and should have issued an
additional 1.36 million shares of Sunoco common stock. While the Company be-
lieves the exchange ratio was correctly calculated, in the fourth quarter of
1999 it agreed to settle the lawsuit, subject to court approval. Accordingly, a
$14 million charge ($9 million after tax) was recorded in 1999 in connection
with the settlement.

During the 1997-99 period, the Company repurchased 8,260,950 shares of its com-
mon stock and 853,580 of its depositary shares for $335 million. At December
31, 1999, the Company has a remaining authorization from its Board of Directors
("Board") to purchase up to $136 million of Company stock in the open market or
through privately negotiated transactions from time to time depending on pre-
vailing market conditions.

The Company's Articles of Incorporation authorize the issuance of up to
15,000,000 shares of preference stock without par value, subject to approval by
the Board. The Board also has authority to fix the number, designation, rights,
preferences and limitations of these shares, subject to applicable laws and the
provisions of the Articles of Incorporation.

On February 1, 1996, the Company adopted a shareholder rights plan and desig-
nated 1,743,019 shares of its preference stock as Series B participating cumu-
lative preference stock. Pursuant to the plan, the Company declared a dividend
of one stock purchase right ("Right") for each share of common stock outstand-
ing on February 12, 1996. A Right will be granted for each share of common
stock issued after such date and prior to the expiration date of the rights
plan. The Rights are attached to the common stock until they become exercis-
able. Generally, the Rights become exercisable a specified period after a party
acquires 15 percent or more of the aggregate outstanding common stock or an-
nounces a tender offer for 15 percent or more of the common stock. Each Right
initially entitles a holder to purchase one one-hundredth of a share of the Se-
ries B participating cumulative preference stock for $100. After a party has
acquired 15 percent or more of the common stock, each Right will entitle a
holder to pay $100 for the number of shares of Company common stock (or in cer-
tain situations, common stock of the acquiring party) having a then current
market value of $200. Alternatively, the Company has the option to exchange one
share of Company common stock for each Right at any time after a party has ac-
quired at least 15 percent but less than 50 percent of the common stock. The
Company may redeem each Right for $.01 per Right at any time until the end of a
specified period after a party has acquired 15 percent or more of the common
stock. In general, none of the benefits of the Rights will be available to a
holder of 15 percent or more of the common stock. The Rights will expire on
February 12, 2006, unless earlier exchanged or redeemed.

The Employee Option Plan ("EOP") provides for the award of stock options to all
employees (other than executives) of the Company and certain subsidiaries. The
awards have a ten-year term, are not exercisable until two years after the date
of grant and permit optionees to purchase Company common stock at its fair mar-
ket value on the date of grant. Since its adoption, stock option awards for
1,963,280 shares were made to eligible employees under EOP.

16. Management Incentive Plans

Sunoco's principal management incentive plans are the Executive Incentive Plan
("EIP") and the Long-Term Performance Enhancement Plan ("LTPEP"). The EIP pro-
vides for the payment of annual cash incentive awards while the LTPEP, which
succeeded the Executive Long-Term Stock Investment Plan in May 1997, provides
for the award of stock options, common stock units and related rights to offi-
cers and other key employees of Sunoco. The option awards under LTPEP have a
ten-year term, are not exercisable until two years after the date of grant and
permit optionees to purchase Company common stock at the fair market value on
the date of grant. No awards may be granted under LTPEP after December 31,
2001, unless the Board extends this date to a date no later than December 31,
2006. Aggregate charges against income for Sunoco's principal management incen-
tive plans for 1999, 1998 and 1997 were $2, $13 and $17 million, respectively.

The Company follows the method of accounting for employee stock compensation
plans prescribed by Accounting Principles Board Opinion No. 25. In accordance
with APB No. 25, the Company has not recognized compensation expense for stock
options because the exercise price of the options equals the market price of
the underlying stock on the date of grant, which is the measurement date. Had
the alternative method of accounting for employee stock compensation plans pre-
scribed by Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" been followed, the pro forma impact on Sunoco's net
income and net income per share of common stock on a diluted basis would have
been as follows:

The pro forma amounts above are based upon the estimated fair values of $6.12,
$7.52 and $10.59 per option granted during 1999, 1998 and 1997, respectively.
These values are calculated using the Black-Scholes option pricing model based
on the following weighted-average assumptions:

17. Financial Instruments

The estimated fair value of financial instruments has been determined based on
the Company's assessment of available market information and appropriate valua-
tion methodologies. However, these estimates may not necessarily be indicative
of the amounts that the Company could realize in a current market exchange.

Sunoco's current assets (other than inventories and deferred income taxes) and
current liabilities are financial instruments. The estimated fair value of
these financial instruments approximates their carrying amounts. At December
31, 1999 and 1998, the estimated fair values of Sunoco's long-term debt were
$898 and $917 million, respectively, compared to carrying amounts of $878 and
$823 million, respectively. Long-term debt which is publicly traded was valued
based on quoted market prices while the fair value of other debt issues was es-
timated by management based upon current interest rates available to Sunoco at
the respective balance sheet dates for similar issues.

The Company guarantees the debt of affiliated companies and others (Note 14).
Due to the complexity of these guarantees and the absence of any market for
these financial instruments, the Company does not believe it is practicable to
estimate their fair value.

Sunoco uses a variety of off-balance sheet commodity-based financial and nonfi-
nancial derivative instruments for hedging purposes. Sunoco is at risk for pos-
sible changes in the market value for these derivative instruments. However, it
is anticipated that such risk would be mitigated by price changes in the under-
lying hedged transactions. In addition, Sunoco is exposed to credit risk in the
event of nonperformance by counterparties. Management believes this risk is
negligible as its counterparties are either regulated by exchanges or are major
international financial institutions with high credit ratings. Market and
credit risks associated with all of Sunoco's derivative contracts are reviewed
regularly by management.

Sunoco uses futures and forward contracts to achieve ratable pricing of its
crude oil purchases and to convert certain refined product sales from fixed to
floating price. In addition, price collars, swaps and option contracts are used
to lock in a portion of the Company's electricity and natural gas costs. Sunoco
also uses swaps, price collars and other option contracts from time to time to
hedge against significant increases in crude oil prices and to lock in what Su-
noco considers to be acceptable wholesale margins for various refined products.
At December 31, 1999, margins for approximately 14 million barrels (6 percent
of the Company's expected 2000 wholesale fuels sales) had been locked in.

18. Acquisition of Phenol Facility

On June 30, 1998, Sunoco acquired the Philadelphia phenol facility of
AlliedSignal Inc. ("Allied") for $157 million. Of this amount, $48 million was
paid on the acquisition date, $41 million was paid in the second half of 1998
and the remaining $68 million was paid in 1999. In connection with this acqui-
sition, Sunoco has entered into a long-term contract to supply Allied 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.

The acquisition has been accounted for as a purchase. The results of operations
of the phenol facility have been included in the consolidated statements of in-
come since the date of acquisition. The purchase price has been allocated to
the assets acquired and liabilities assumed based on their relative fair market
values at the acquisition date. The following is a summary of the effects of
this transaction on Sunoco's consolidated financial position as of the acquisi-
tion date:

The unaudited pro forma net income and net income per share of common stock on
a diluted basis of Sunoco for the years ended December 31, 1998 and 1997, as if
the acquisition of the phenol facility had occurred on January 1, 1997, were
$294 million ($3.09 per share) and $280 million ($2.87 per share), respective-
ly. The pro forma information does not purport to be indicative of the results
that actually would have been obtained if the combined operations had been con-
ducted during the periods presented and is not intended to be a projection of
future results.

19. Business Segment Information

Sunoco is principally a petroleum refiner and marketer with interests in
cokemaking. Sunoco's operations are organized into seven business segments.

The Northeast Refining segment manufactures petroleum products and petrochemi-
cal feedstocks at Sunoco's Marcus Hook and Philadelphia refineries and sells
these products to other Sunoco businesses and to wholesale and industrial cus-
tomers. The Northeast Marketing segment sells gasoline and middle distillates
at retail and operates convenience stores in the Mid-Atlantic and New England
states. The Chemicals segment manufactures base commodity and intermediate pet-
rochemicals primarily at Sunoco's Marcus Hook and Philadelphia refineries and
at its Philadelphia phenol facility, its Brandenburg, KY, ethylene/ethylene ox-
ide plant and its Mont Belvieu, TX, joint venture MTBE facility. This segment
also distributes and markets these products. The Lubricants segment manufac-
tures, blends, packages and markets a broad line of paraffinic and aromatic lu-
bricating and specialty oils produced at Sunoco's Tulsa and Puerto Rico refin-
eries and manufactures and markets at wholesale the related fuels produced at
these facilities. The MidAmerica Marketing & Refining segment sells gasoline
and middle distillates at retail and operates convenience stores in the Mid-
west. It also manufactures and markets fuels and petrochemicals produced at
Sunoco's Toledo refinery. The Logistics segment operates crude oil and refined
product pipelines and engages in domestic lease crude oil acquisition and re-
lated trucking operations, crude oil and product terminalling and petroleum
transport operations. Logistics operations are conducted primarily in the
Northeast, Midwest and South Central regions of the United States. The Coke
segment makes high-quality coke at Sunoco's Indiana Harbor facility in East
Chicago, IN, and its Jewell facility in Vansant, VA, and produces coal from
mines in Virginia primarily for use at the Jewell cokemaking facility. Substan-
tially all of the coke sales are made under long-term contracts with two cus-

Income tax amounts give effect to the tax credits earned by each segment. Over-
head expenses that can be identified with a segment have been included as de-
ductions in determining the segment's operating profit and profit contribution.
Net financing expenses and other consist principally of interest cost, debt and
other financing expenses less interest income and interest capitalized.
Intersegment revenues are accounted for based on the prices negotiated by the
segments which approximate market. Identifiable assets are those assets that
are utilized within a specific segment.

Report of Management

To the Shareholders of Sunoco, Inc.

 The accompanying consolidated financial statements of Sunoco, Inc. and its
subsidiaries ("Sunoco") and the related information are the responsibility of
management. The financial statements, which include amounts based on informed
estimates and judgments, were prepared using generally accepted accounting
principles deemed appropriate in the circumstances. Management believes that
these financial statements present fairly, in all material respects, Sunoco's
financial position, results of operations and cash flows. Other financial in-
formation presented in this Annual Report is consistent with that in the finan-
cial statements.
 To fulfill its responsibility for the financial statements, Sunoco maintains a
system of internal controls which in management's opinion provides reasonable
assurance of achieving the objectives of internal control. These objectives in-
clude safeguarding of assets from loss through unauthorized use or disposition
and maintaining reliable records permitting the preparation of financial state-
ments and accountability for assets. The system of internal controls is subject
to ongoing evaluation of its continuing effectiveness.
 Sunoco's independent auditors, Ernst & Young LLP, have expressed an opinion on
the fairness of management's financial statements in the report presented on
this page.
 The Audit Committee of the Board of Directors, which met eight times during
1999, is comprised of directors who meet the independence requirements of the
New York Stock Exchange. It assists the Board of Directors in discharging its
duties relating to accounting and reporting practices and internal controls,
and it assesses the performance and recommends the appointment of independent
auditors. Both the independent auditors and Sunoco's internal auditors have un-
restricted access to the Committee to discuss audit findings and other finan-
cial matters.

Report of Independent Auditors

To the Shareholders and Board of Directors,
Sunoco, Inc.

 We have audited the accompanying consolidated balance sheets of Sunoco, Inc.
and subsidiaries at December 31, 1999 and 1998, and the related consolidated
statements of income, changes in shareholders' equity and cash flows for each
of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our responsibil-
ity is to express an opinion on these financial statements based on our audits.
 We conducted our audits in accordance with auditing standards generally ac-
cepted in the United States. 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 ba-
sis, evidence supporting the amounts and disclosures in the financial state-
ments. An audit also includes assessing the accounting principles used and sig-
nificant estimates made by management, as well as evaluating the overall finan-
cial 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 consolidated financial position of Sunoco, Inc. and
subsidiaries at December 31, 1999 and 1998 and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally ac-
cepted in the United States.

  March 6 and the reduced crude oil processed at this facility after the
  reconfiguration (approximately 35,000 barrels per day) are excluded from the
