NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)



|1. | General.
|-- | --------

The accompanying condensed consolidated
financial statements are presented in accordance with the requirements of Form 10-Q and U.S. generally accepted accounting principles for interim financial reporting. They do not include all disclosures normally made in financial statements
contained in Form 10-K. In managements opinion, all adjustments necessary for a fair presentation of the results of operations, financial position and cash flows for the periods shown have been made. All such adjustments are of a normal
recurring nature. Results for the three months ended March 31, 2006 are not necessarily indicative of results for the full-year 2006.

Share and per-share data (except par value) presented for all periods reflect the effect of a two-for-one stock split, which was effected in the form of a common stock dividend distributed on August 1, 2005 (Note 8).



|2. | Minority Interests.
|-- | -------------------

Cokemaking Operations

Since 1995, Sunoco has received, in four separate transactions, a total of $724 million in exchange for interests in its Jewell and Indiana
Harbor cokemaking operations. Sunoco did not recognize any gain at the dates of these transactions because the third-party investors were entitled to a preferential return on their investments. The preferential returns are currently equal to 98
percent of the cash flows and tax benefits from the respective cokemaking operations during the preferential return periods, which continue until the investors recover their investments and achieve a cumulative annual after-tax return that averages
approximately 10 percent. Income is recognized as coke production and sales generate cash flows and tax benefits which are allocated to Sunoco and the third-party investors, while expense is recognized to reflect the investors preferential
returns.

The preferential return period for the Jewell operation is projected to end during 2011, while the preferential return period for
the Indiana Harbor operation is projected to end during 2007. Due to the difficulty of forecasting operations and tax benefits into the future, the accuracy of these estimates is subject to considerable uncertainty. The estimated lengths of these
preferential return periods are based upon the Companys current expectations of future cash flows and tax benefits, which are impacted by sales volumes and prices, raw material and operating costs, capital expenditure levels and the ability to
recognize tax benefits under the current tax law (see below). Higher-than-expected cash flows and tax benefits will shorten the investors preferential return periods, while lower-than-expected cash flows and tax benefits will lengthen the
periods.

Following the expiration of these preferential return periods, the investor in the Jewell operation will be entitled to a minority
interest in the related cash flows and tax benefits amounting to 18 percent, while the investors in the Indiana Harbor operation will be entitled to a minority interest in the related cash flows and tax benefits initially amounting to 34 percent and
thereafter declining to 10 percent by 2038.

Under existing tax law, the coke production at Jewell and Indiana Harbor is not eligible to
generate nonconventional fuel tax credits after 2007. The energy policy legislation enacted in August 2005 includes additional tax credits pertaining to a portion of the coke production at Jewell, all of the coke production at Haverhill, where
operations commenced in March 2005, and all future domestic coke plants placed into service by January 1, 2010. The new credits cover a four-year period, effective January 1, 2006 or the date any new facility is placed into service, if
later. However, prior to their

expiration dates, all of the tax credits would be phased out, on a ratable basis, if the average annual
price of domestic crude oil at the wellhead is within a certain inflation-adjusted price range. (This range was $53.20 to $66.79 per barrel for 2005.) The domestic wellhead price averaged $56.84 per barrel for the two months ended February 28,
2006, $55.82 per barrel for the month of February 2006 and $50.26 per barrel for the year ended December 31, 2005. Based upon the Companys estimate of domestic wellhead prices for the first quarter of 2006, Sun Coke recorded only 85
percent of the benefit of the tax credits that otherwise would have been available without regard to these phase-out provisions. The estimated impact of this phase-out reduced earnings for the first quarter of 2006 by $1 million after tax. The
ultimate amount of the credits to be earned during 2006 will be based upon the average annual price of domestic crude oil at the wellhead. In addition, if the tax credits were phased out, the Company could be required under tax indemnity agreements
to make cash payments to the third-party investors. Payments would be required only if the expected end of the applicable preferential return period was extended by two years or more and if the respective third-party investor was expected to achieve
a cumulative after-tax return of less than approximately 6.5 percent. The Company currently does not believe that any payments would be required, even if the average annual wellhead crude oil price were to exceed the threshold at which the credits
are completely phased out.

The Company also indemnifies the third-party investors for certain tax benefits available to them during the
preferential return period in the event the Internal Revenue Service disallows the tax deductions and benefits allocated to the third parties or if there is a change in the tax laws that reduces the amount of nonconventional fuel tax credits. These
tax indemnifications are in effect until the applicable tax returns are no longer subject to Internal Revenue Service review. In certain of these cases, if performance under the indemnification is required, the Company also has the option to
purchase the third-party investors interests. Although the Company believes it is remote that it will be required to make any payments under these indemnifications, at March 31, 2006, the maximum potential payment under these tax
indemnifications and the options to purchase the third-party investors interests, if exercised, would have been approximately $620 million. If this were to occur, the minority interest balance would be reduced by approximately $185 million.

The following table sets forth the minority interest balances and the changes in these balances attributable to the third-party
investors interests in cokemaking operations (in millions of dollars):

Logistics Operations

In the second quarter of 2005, Sunoco Logistics Partners L.P. (the Partnership), a master limited partnership in which Sunoco has an ownership
interest, issued 2.8 million limited partnership units at a price of $37.50 per unit. Proceeds from the offering, net of underwriting discounts and offering expenses, totaled approximately $99 million. These proceeds were used to redeem an
equal number of limited partnership units owned by Sunoco. In the third quarter of 2005, the Partnership issued an additional 1.6 million limited partnership units at a price of $39.00 per unit. Proceeds from the offering, which totaled
approximately $61 million, net of underwriting discounts and offering expenses, were used by the Partnership principally to repay a portion of the borrowings under its revolving credit facility.

As of March 31, 2006, Sunoco owned 12.06 million limited partnership units consisting of 6.37 million common units and 5.69 million
subordinated units. Distributions on Sunocos subordinated units are payable only after the minimum quarterly distributions of $.45 per unit for the common units held by the public and Sunoco, including any arrearages, have been made. The
subordinated units convert to common units if certain financial tests related to earning and paying the minimum quarterly distribution for the preceding three consecutive one-year periods have been met. In February 2006 and 2005, when the quarterly
cash distributions pertaining to the fourth quarters of 2005 and 2004 were paid, the first two three-year requirements were satisfied. As a result, a total of 5.70 million of Sunocos subordinated units have been converted to common units,
2.85 million each in February 2006 and February 2005. If the Partnership continues to meet the financial tests through the fourth quarter of 2006, all of Sunocos remaining 5.69 million subordinated units would be converted to common
units in February 2007.

The Partnerships issuance of common units to the public has resulted in an increase in the value of
Sunocos proportionate share of the Partnerships equity as the issuance price per unit exceeded Sunocos carrying amount per unit at the time of issuance. The resultant gain to Sunoco on these transactions, which totaled
approximately $125 million pretax at March 31, 2006, has been deferred as a component of minority interest in the Companys condensed consolidated balance sheets as the common units issued do not represent residual interests in the
Partnership due to Sunocos ownership of the subordinated units. The deferred gain would be recognized in income when Sunocos remaining subordinated units convert to common units at which time the common units become the residual
interests.

In early May 2006, the Partnership commenced offerings utilizing its shelf registration statement under which it expects to
issue $175 million of senior notes due 2016 and 2.4 million limited partnership units. The proceeds from these offerings, net of underwriting discounts and offering expenses, total approximately $272 million. The Partnership intends to use
these proceeds to repay the outstanding borrowings under its revolving credit facility, which amounted to $216 million at March 31, 2006, and to fund additional growth capital opportunities. Both offerings are expected to be completed on
May 8, 2006. Upon completion of the equity offering, Sunocos interest in the Partnership, including its 2 percent general partnership interest, is expected to decrease from 48 percent to 44 percent. The accounts of the Partnership will
continue to be included in Sunocos consolidated financial statements.

Logistics Assets  In March 2006, Sunoco Logistics Partners L.P. purchased two separate crude oil pipeline
systems and related storage facilities located in Texas, one from affiliates of Black Hills Energy, Inc. (Black Hills) for $41 million and the other from affiliates of Alon USA Energy, Inc. (Alon) for $68 million. The Black
Hills acquisition also includes a lease acquisition marketing business and related inventory. The Alon pipeline system is currently idled and is scheduled to be returned to service on June 1, 2006. The Partnership also expects to complete a $12
million project to expand capacity on the Alon pipeline system and to construct new tankage at the Nederland terminal to service these new volumes

by the end of 2006. In August 2005, the Partnership completed the acquisition of another crude oil
pipeline system and related storage facilities located in Texas from ExxonMobil for $100 million. In December 2005, the Partnership also completed the acquisition of an ownership interest in the Mesa Pipeline from Chevron for $5 million, which
coupled with the 7.2 percent interest it acquired from Sunoco, gave it a 37.0 percent ownership interest. The above acquisitions were initially funded with proceeds from borrowings under the Partnerships revolving credit facility (Note 2).

The purchase price of the Black Hills acquisition has been allocated to the assets acquired based on their estimated fair market values at
the acquisition date. The Partnership has engaged an independent appraisal firm to value the Black Hills assets. The appraisal is expected to be completed during the second quarter of 2006. The following is a summary of the effects of this
transaction on Sunocos consolidated financial position (in millions of dollars):

The purchase price of the other acquisitions has been included in properties, plants and equipment
in the condensed consolidated balance sheets. No pro forma information has been presented since the acquisitions were not material in relation to Sunocos condensed consolidated results of operations.

Divestments

Retail Portfolio Management
Program  A Retail Portfolio Management (RPM) program is ongoing, which is selectively reducing the Companys invested capital in Company-owned or leased retail sites. During the 2003-2006 period, selected sites are being
divested. Most of the sites are being converted to contract dealers and distributors thereby retaining most of the gasoline sales volume attributable to the divested sites within the Sunoco branded business. The Company expects to generate
divestment proceeds of approximately $230 million, of which $180 million has been received through March 31, 2006 related to the sale of 341 sites. During the first three months of 2006 and 2005, net gains of $4 and $3 million, respectively ($3
and $2 million after tax, respectively), were recognized in other income, net, in the condensed consolidated statements of income in connection with the RPM program. The Company expects the RPM program to generate additional gains during the
remainder of 2006.

Other Matters

Phenol Supply Contract Dispute  During the third quarter of 2005, an arbitrator ruled that Sunoco was liable in an arbitration proceeding for breaching a supply agreement concerning the prices charged to Honeywell International Inc.
(Honeywell) for phenol produced at Sunocos Philadelphia chemical plant from June 2003 through April 2005. In January 2006, the arbitrator ruled that Sunoco should bill Honeywell based on the pricing formula established in the
arbitration until a second arbitration, set to begin in the second quarter of 2006, finalizes pricing for 2005 and beyond (see below). Damages of approximately $95 million ($56 million after tax), including prejudgment interest, were assessed, of
which $27, $48 and $20 million pertained to 2005, 2004 and 2003, respectively. Such damages,

which were paid to Honeywell in April 2006, were recorded as a charge against earnings in the 2005
consolidated statement of income ($78 million in the third quarter and $17 million in the fourth quarter). In March 2006, a U.S. District Court judge upheld the arbitrators ruling. The phenol supply agreement provides for a reopener for
pricing on and after January 1, 2005 and sets forth specific standards for determining such pricing. The parties have been unsuccessful in negotiating the post-2004 price, and a new price will be determined in a second arbitration to be held
before a different arbitrator. Sunoco believes the basis for the post-2004 pricing is substantially different from the basis of the award in the first arbitration.

Power Contract Restructuring  In December 2004, Sunoco and a subsidiary of FPL Energy (FPL) agreed to a restructuring of an agreement under which Sunoco may purchase steam from a natural gas fired
cogeneration power plant owned and operated by FPL at Sunocos Marcus Hook refinery. Under the restructured terms, FPL surrendered its easement interest in land adjacent to the power plant on which four auxiliary boilers were constructed,
thereby transferring ownership of the auxiliary boilers with an estimated fair market value of $33 million to Sunoco. FPL operates the auxiliary boilers on Sunocos behalf. When the cogeneration plant is in operation, Sunoco has the option to
purchase steam from the facility at a rate equivalent to that set forth in the original agreement. As part of the restructuring, Sunoco has agreed to a long-term lease of the land on which the cogeneration facility was constructed to FPL and to
modify certain terms in the existing agreement for an aggregate cash payment of $48 million, most of which is attributable to prepaid rent. Sunoco received this $48 million payment in January 2005. No gain or loss was recognized in connection with
the restructuring. Upon completion of the restructured agreement in January 2005, deferred revenue of $81 million was recorded in other deferred credits and liabilities in the condensed consolidated balance sheet, which is being amortized into
income over the 30-year term of the contract.



|4. | Stock-Based Compensation.
|-- | -------------------------

Effective January 1, 2006,
the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), utilizing the modified-prospective method. SFAS No. 123R revised the accounting for
stock-based compensation required by Statement of Financial Accounting Standards No. 123 Accounting for Stock-Based Compensation (SFAS No. 123). Among other things, SFAS No. 123R requires a fair-value-based
method of accounting for share-based payment transactions, which is similar to the method followed by the Company under the provisions of SFAS No. 123. SFAS No. 123R also requires the use of a non-substantive vesting period approach for
new share-based payment awards that vest when an employee becomes retirement eligible as is the case under Sunocos share-based awards (i.e., the vesting period cannot exceed the date an employee becomes retirement eligible). The effect will be
to accelerate expense recognition compared to the vesting period approach that Sunoco previously followed under SFAS No. 123. Adoption of SFAS No. 123R did not have a material effect on the Companys results of operations for the
three-month period ended March 31, 2006. However, assuming the fair value of awards to be granted in the fourth quarter of 2006 are similar to the value of those granted in December 2005, the Company currently estimates that its after-tax
compensation expense under SFAS No. 123R will be approximately $5-$10 million higher in 2006 than it would have been under SFAS No. 123 as a result of the accelerated expense recognition. The future impact of the non-substantive vesting
period will be dependent upon the value of future stock-based awards granted to employees who are eligible to retire prior to the normal vesting periods of the awards.

The stock options granted under the Companys management incentive plans have a 10-year term, are
not exercisable until two years after the date of grant and permit optionees to purchase Company stock at its fair market value on the date of grant. Under SFAS No. 123, the fair value of the stock options was estimated using the Black-Scholes
option pricing model. Use of this model requires the Company to make certain assumptions regarding the term that the options are expected to be outstanding (expected life), as well as regarding the risk-free interest rate, the
Companys expected dividend yield and the expected volatility of the Companys stock price during the period the options are expected to be outstanding. The expected life and dividend yield are estimated based on historical experience. The
risk-free interest rate is based on the U.S. Treasury yield curve at the date of grant for periods that are approximately equal to the expected life. The Company uses historical share prices, for a period equivalent to the options expected
life, to estimate the expected volatility of the Companys share price. The Company continues to use the Black-Scholes option pricing model to estimate the fair value of stock options under SFAS No. 123R.

During the three months ended March 31, 2006 and 2005, 46,870 and 564,732 stock options, respectively, were exercised with an intrinsic value of $3
and $17 million, respectively. Cash received from the exercise of options during the three months ended March 31, 2006 totaled $1 million and the related tax benefit realized was $1 million. At March 31, 2006, there were 1,486,886 stock
options outstanding, of which 286,536 were exercisable. As of this date, the aggregate intrinsic value of all of the outstanding stock options was $47 million, while the aggregate intrinsic value and the weighted average remaining contractual term
of the exercisable options was $17 million and six years, respectively.

Common stock unit awards under the Companys management
incentive plans mature upon completion of a three-year service period or upon attainment of predetermined performance targets during the three-year period. For the performance-based awards, adjustments for attainment of performance targets can range
from 0200 percent of the award grant. Awards are payable in cash or common stock. Awards to be paid in cash are classified as liabilities in the Companys condensed consolidated balance sheets and are re-measured for expense purposes at
fair value each period (based on the fair value of an equivalent number of Sunoco common shares at the end of the period) with any change in fair value recognized as an increase or decrease in income. For awards to be settled in common stock, the
fair value for expense purposes is based on the closing price of the Companys shares on the date of grant.

During the three months
ended March 31, 2006 and 2005, 527,000 and 276,000 common stock units, respectively, were settled in cash and 69,200 and 53,200 common stock units, respectively, were settled in common stock. The intrinsic value of the common stock units that
were settled in cash during the three months ended March 31, 2006 and 2005 totaled $43 and $12 million, respectively, while the intrinsic value of the common stock unit awards that were settled in common stock totaled $5 and $2 million,
respectively. At March 31, 2006, excluding any potential adjustment for performance, there were 531,140 common stock units outstanding payable in cash and 162,115 payable in stock with an aggregate intrinsic value of $41 and $13 million,
respectively.

For the three months ended March 31, 2006 and 2005, the Company recognized stock-based compensation expense of $10 and
$13 million, respectively, and related tax benefits of $4 and $5 million, respectively. As of March 31, 2006, total compensation cost related to nonvested awards not yet recognized was $49 million, and the weighted-average period over which
this cost is expected to be recognized in income is 1.7 years. The stock-based compensation expense and the total compensation cost related to nonvested awards not yet recognized reflect the Companys estimates of performance factors pertaining
to performance-based common stock unit awards.

|6. | Commitments and Contingent Liabilities.
|-- | ---------------------------------------

Commitments

Sunoco is contingently liable under various arrangements which guarantee debt of third parties aggregating to approximately $6 million at
March 31, 2006. At this time, management does not believe that it is likely that the Company will have to perform under any of these guarantees.

Over the years, Sunoco has sold thousands of retail gasoline outlets as well as refineries, terminals, coal mines, oil and gas properties and various other assets. In connection with these sales, the Company has
indemnified certain purchasers for potential environmental and other contingent liabilities related to the period prior to the transaction dates. In most cases, the effect of these arrangements was to afford protection for the purchasers with
respect to obligations for which the Company was already primarily liable. While some of these indemnities have spending thresholds which must be exceeded before they become operative, or limits on Sunocos maximum exposure, they generally are
not limited. The Company recognizes the fair value of the obligations undertaken for all guarantees entered into or modified after January 1, 2003. In addition, the Company accrues for any obligations under these agreements when a loss is
probable and reasonably estimable. The Company cannot reasonably estimate the maximum potential amount of future payments under these agreements.

Effective January 1, 2001, Sunoco completed the acquisition of Aristech Chemical Corporation (Aristech), a wholly owned subsidiary of Mitsubishi Corporation (Mitsubishi), for $506 million in cash and the
assumption of $163 million of debt. Contingent payments (the earn out) may also be made if realized margins for polypropylene and phenol exceed certain agreed-upon thresholds through 2006. For 2005, a $14 million payment was earned,
which was paid in April 2006. Any additional contingent payment earned in 2006 is limited to $90 million. All earn-out payments are being treated as adjustments to the purchase price. In addition, Mitsubishi is responsible for up to $100 million of
any potential environmental liabilities of the business identified through January 1, 2026 arising out of or related to the period prior to the acquisition date.

Environmental Remediation Activities

Sunoco is subject to extensive and frequently changing federal, state
and local laws and regulations, including, but not limited to, those relating to

##### Table of Contents

the discharge of materials into the environment or that otherwise deal with the protection of the
environment, waste management and the characteristics and composition of fuels. As with the industry generally, compliance with existing and anticipated laws and regulations increases the overall cost of operating Sunocos businesses, including
remediation, operating costs and capital costs to construct, maintain and upgrade equipment and facilities.

Existing laws and regulations
result in liabilities and loss contingencies for remediation at Sunocos facilities and at formerly owned or third-party sites. The accrued liability for environmental remediation is classified in the condensed consolidated balance sheets as
follows (in millions of dollars):

Sunocos accruals for environmental remediation activities reflect managements
estimates of the most likely costs that will be incurred over an extended period to remediate identified conditions for which the costs are both probable and reasonably estimable. Engineering studies, historical experience and other factors are used
to identify and evaluate remediation alternatives and their related costs in determining the estimated accruals for environmental remediation activities. Losses attributable to unasserted claims are also reflected in the accruals to the extent they
are probable of occurrence and reasonably estimable.

Total future costs for the environmental remediation activities identified above will
depend upon, among other things, the identification of any additional sites, the determination of the extent of the contamination at each site, the timing and nature of required remedial actions, the technology available and needed to meet the
various existing legal requirements, the nature and terms of cost-sharing arrangements with other potentially responsible parties, the availability of insurance coverage, the nature and extent of future environmental laws, inflation rates and the
determination of Sunocos liability at the sites, if any, in light of the number, participation level and financial viability of the other parties. Management believes it is reasonably possible (i.e., less than probable but

greater than remote) that additional environmental remediation losses will be incurred. At March 31,
2006, the aggregate of the estimated maximum additional reasonably possible losses, which relate to numerous individual sites, totaled approximately $85 million. However, the Company believes it is very unlikely that it will realize the maximum
reasonably possible loss at every site. Furthermore, the recognition of additional losses, if and when they were to occur, would likely extend over many years and, therefore, likely would not have a material impact on the Companys financial
position.

Under various environmental laws, including the Resource Conservation and Recovery Act (RCRA) (which relates to solid
and hazardous waste treatment, storage and disposal), Sunoco has initiated corrective remedial action at its facilities, formerly owned facilities and third-party sites. At the Companys major manufacturing facilities, Sunoco has consistently
assumed continued industrial use and a containment/remediation strategy focused on eliminating unacceptable risks to human health or the environment. The remediation accruals for these sites reflect that strategy. Accruals include amounts to prevent
off-site migration and to contain the impact on the facility property, as well as to address known, discrete areas requiring remediation within the plants. Activities include closure of RCRA solid waste management units, recovery of hydrocarbons,
handling of impacted soil, mitigation of surface water impacts and prevention of off-site migration.

Many of Sunocos current
terminals are being addressed with the above containment/remediation strategy. At some smaller or less impacted facilities and some previously divested terminals, the focus is on remediating discrete interior areas to attain regulatory closure.

Sunoco owns or operates certain retail gasoline outlets where releases of petroleum products have occurred. Federal and state laws and
regulations require that contamination caused by such releases at these sites and at formerly owned sites be assessed and remediated to meet the applicable standards. The obligation for Sunoco to remediate this type of contamination varies,
depending on the extent of the release and the applicable laws and regulations. A portion of the remediation costs may be recoverable from the reimbursement fund of the applicable state, after any deductible has been met.

Future costs for environmental remediation activities at the Companys marketing sites also will be influenced by the extent of MTBE contamination of
groundwater, the cleanup of which will be driven by thresholds based on drinking water protection. Though not all groundwater is used for drinking, several states have initiated or proposed more stringent MTBE cleanup requirements. Cost increases
result directly from extended remedial operations and maintenance on sites that, under prior standards, could otherwise have been completed. Cost increases will also result from installation of additional remedial or monitoring wells and purchase of
more expensive equipment because of the presence of MTBE. While actual cleanup costs for specific sites are variable and depend on many of the factors discussed above, expansion of similar MTBE remediation thresholds to additional states or adoption
of even more stringent requirements for MTBE remediation would result in further cost increases.

The accrued liability for hazardous waste
sites is attributable to potential obligations to remove or mitigate the environmental effects of the disposal or release of certain pollutants at third-party sites pursuant to the Comprehensive Environmental Response Compensation and Liability Act
(CERCLA) (which relates to releases and remediation of hazardous substances) and similar state laws. Under CERCLA, Sunoco is potentially subject to 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 March 31, 2006, Sunoco had been named as a PRP at 36 sites identified or
potentially identifiable as Superfund sites under federal and state law. The Company is usually one of a number of companies identified as a PRP at a site. 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.

Management believes that none of the current remediation locations, which are in various stages of ongoing remediation, is individually material to Sunoco
as its largest accrual for any one Superfund site, operable unit or remediation area was less than $4 million at March 31, 2006. As a result, Sunocos exposure to adverse developments with respect to any individual site is not expected to
be material. However, if changes in environmental regulations occur, such changes could impact multiple Sunoco facilities and formerly owned and third-party sites at the same time. As a result, from time to time, significant charges against income
for environmental remediation may occur.

The Company maintains insurance programs that cover certain of its existing or potential
environmental liabilities, which programs vary by year, type and extent of coverage. For underground storage tank remediations, the Company can also seek reimbursement through various state funds of certain remediation costs above a deductible
amount. For certain acquired properties, the Company has entered into arrangements with the sellers or others that allocate environmental liabilities and provide indemnities to the Company for remediating contamination that occurred prior to the
acquisition dates. Some of these environmental indemnifications are subject to caps and limits. No accruals have been recorded for any potential contingent liabilities that will be funded by the prior owners as management does not believe, based on
current information, that it is likely that any of the former owners will not perform under any of these agreements. Other than the preceding arrangements, the Company has not entered into any arrangements with third parties to mitigate its exposure
to loss from environmental contamination. Claims for recovery of environmental liabilities that are probable of realization totaled $22 million at March 31, 2006 and are included principally in deferred charges and other assets in the condensed
consolidated balance sheets.

Environmental Regulatory Matters

The U.S. Environmental Protection Agency (EPA) adopted rules under the Clean Air Act (which relates to emissions of materials into the air)
that phase in limitations on the sulfur content of gasoline beginning in 2004 and the sulfur content of on-road diesel fuel beginning in mid-2006 (Tier II). The rules include banking and trading credit systems, which could provide
refiners flexibility through 2006 for the low-sulfur gasoline and through May 2010 for the on-road low-sulfur diesel. These rules are expected to have a significant impact on Sunoco and its operations, primarily with respect to the capital and
operating expenditures at its five refineries. The Tier II capital spending is expected to be essentially completed in 2006, while the higher operating costs will be incurred when the low-sulfur fuels are produced. The Companys estimate of
total capital outlays to comply with the Tier II low-sulfur gasoline and on-road diesel requirements is approximately $750 million. Capital spending to meet these requirements totaled $689 million through March 31, 2006. In May 2004, the EPA
adopted a third rule which will phase in limitations on the allowable sulfur content in off-road diesel fuel beginning in mid-2007. The off-road diesel rule is not expected to require significant capital expenditures by Sunoco. The ultimate impact
of the rules may be affected by such factors as technology selection, the

effectiveness of the systems pertaining to banking and trading credits, timing uncertainties created by
permitting requirements and construction schedules and any effect on prices created by changes in the level of gasoline and diesel fuel production.

In 1997, the EPA promulgated new, more stringent National Ambient Air Quality Standards (NAAQS) for ozone and fine particles, which has resulted in identification of non-attainment areas throughout the country, including Texas,
Pennsylvania, Ohio, New Jersey and West Virginia, where Sunoco operates facilities. In 2004, the EPA issued final non-attainment area designations for ozone and fine particles. These standards will result in further controls of nitrogen oxide,
sulfur dioxide and volatile organic compound emissions. The EPA has designated certain areas, including Philadelphia and Houston, as moderate non-attainment areas for ozone, which would require them to meet the ozone requirements by
2010, before currently mandated federal control programs would take effect. If a region is not able to demonstrate attainment by 2010, there would be more stringent offset requirements, and, if a region cannot submit an approvable State
Implementation Plan, there could be a moratorium on new highway projects and imposition of a Federal Implementation Plan, including potentially significant lifestyle changes to bring the region to attainment. However, EPAs designation of ozone
non-attainment areas and the EPAs rule on state implementation are currently being challenged by the State of Ohio, trade associations and health and environmental groups. In 2005, EPA issued a final rule revoking a previously proposed 1-hour
ozone standard and related provisions in favor of a more stringent 8-hour standard. The EPA issued a subsequent rule codifying the revocation of the 1-hour ozone standard for the areas with effective 8-hour ozone non-attainment designations. Both
industry and environmental groups have filed lawsuits challenging various provisions of the final rule. In 2005, the EPA also identified 21 counties which, based on 2003-2004 data, now are in attainment of the fine particles standard. Sunocos
Toledo refinery is within one of these attainment areas. Regulatory programs, when established to implement the EPAs standards, could have an impact on Sunoco and its operations. However, the potential financial impact cannot be reasonably
estimated until the EPA promulgates regulatory programs to attain the standards, and the states, as necessary, develop and implement revised State Implementation Plans to respond to the new regulations.

In August 2005, new federal energy policy legislation was enacted. The act set a new renewable fuels mandate for ethanol use in gasoline (immediately in
California and on May 5, 2006 for the rest of the nation). Although the act did not ban MTBE, Sunoco has decided to discontinue the use of MTBE and increase its use of ethanol in gasoline. While management expects ethanol will continue to be
adequately supplied, this change by Sunoco and other refiners in the industry could have price and supply implications in the marketplace. Any additional Federal and state legislation could also have a significant impact on market conditions and the
profitability of Sunoco and the industry in general.

MTBE Litigation

Sunoco, along with other refiners, manufacturers and sellers of gasoline, owners and operators of retail gasoline sites, and manufacturers of MTBE, are
defendants in approximately 60 cases in 16 states involving the manufacture and use of MTBE in gasoline and MTBE contamination in groundwater. Plaintiffs, which include private well owners, water providers and certain governmental authorities,
allege that refiners and suppliers of gasoline containing MTBE are responsible for manufacturing and distributing a defective product that contaminates groundwater. Plaintiffs are asserting primarily product liability claims but additional claims
are also being



15

##### Table of Contents

asserted including, nuisance, trespass, negligence, violation of environmental laws and deceptive
business practices. Plaintiffs are seeking compensatory damages, and in some cases injunctive relief, exemplary and punitive damages and attorneys fees. All of the public water provider cases have been removed to federal court and consolidated
for pretrial purposes in the U.S. District Court for the Southern District of New York (MDL 1358). Motions to remand these cases to state courts have been denied. Motions to dismiss were denied. Discovery is proceeding in four focus cases. Sunoco is
a defendant in three of these cases. In addition, several of the private well owner cases are moving forward. Sunoco is a focus defendant in two of those cases. Up to this point, for the group of MTBE cases currently pending, there has been
insufficient information developed about the plaintiffs legal theories or the facts that would be relevant to an analysis of potential exposure. Based on the current law and facts available at this time, Sunoco believes that these cases will
not have a material adverse effect on its consolidated financial position.

Conclusion

Many other legal and administrative proceedings are pending or possible against Sunoco from its current and past operations, including proceedings related
to commercial and tax disputes, product liability, antitrust, employment claims, leaks from pipelines and underground storage tanks, natural resource damage claims, premises-liability claims, allegations of exposures of third parties to toxic
substances (such as benzene or asbestos) and general environmental claims. The ultimate outcome of pending proceedings and other matters identified 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 these matters could have a significant impact on results of operations for any future quarter or year. However, management does not believe that any additional liabilities which may arise
pertaining to such matters would be material in relation to the consolidated financial position of Sunoco at March 31, 2006. Furthermore, management does not believe that the overall costs for environmental activities will have a material
impact over an extended period of time on Sunocos cash flows or liquidity.

On July 7, 2005, the Companys Board of Directors (Board) approved a
two-for-one split of Sunocos common stock to be effected in the form of a stock dividend. The shares were distributed on August 1, 2005 to shareholders of record as of July 18, 2005. In connection with the common stock split, the
number of authorized shares of common stock was increased from 200 million to 400 million, and the shares of common stock reserved for issuance pertaining to Sunocos 63/4percent convertible debentures and various employee benefit plans were proportionally increased in accordance with the terms of those respective
agreements and plans.

During the first three months of 2006, the Company repurchased 625,000 shares of common stock for $48 million
under an existing repurchase authorization. At March 31, 2006, the Company had a remaining authorization from its Board to purchase up to $259 million of Company common stock in the open market from time to time depending on prevailing market
conditions and available cash.

The Company increased the quarterly cash dividend paid on common stock from $.15 per share ($.60 per year)
to $.20 per share ($.80 per year) beginning with the second quarter of 2005 and then to $.25 per share ($1.00 per year) beginning with the second quarter of 2006. The estimated $33 million dividend for the second quarter of 2006 has been reflected
as a reduction in earnings employed in the business at March 31, 2006.

On May 4, 2006, the Company
notified the trustee of its 93/8percent debentures of its intention to redeem the debentures. As a result, this
debt, with an aggregate principal amount outstanding of $56 million, has been classified as current portion in the condensed consolidated balance sheet at March 31, 2006. The Company expects to recognize a loss of less than $1 million in the
second quarter of 2006 on the early extinguishment of the debt.

Analysis of Earnings Profile of Sunoco Businesses

In the three-month period ended March 31, 2006, Sunoco earned $79 million, or $.59 per share of common stock on a diluted basis, compared to $116 million, or $.83
per share, for the first quarter of 2005.

The $37 million decrease in net income in the first quarter of 2006 was primarily due to higher expenses ($40
million), including fuel charges; lower chemical margins ($13 million); and lower production of refined products ($7 million). Partially offsetting these negative factors were higher wholesale fuels margins ($10 million); higher retail gasoline
margins ($7 million) and higher earnings from Sunocos Coke ($4 million) and Logistics ($3 million) businesses.

Refining and Supply earned $73 million in the current quarter versus $108 million in the first quarter of 2005. The $35 million decrease in
earnings was due to lower production volumes ($7 million), primarily in Northeast Refining, and higher expenses ($37 million). The lower volumes were mainly a result of a previously announced scheduled maintenance turnaround at the Philadelphia
refinery in late February and early March. In addition, the Toledo refinery also had a planned maintenance turnaround at the end of March and the beginning of April. The higher expenses in the quarter were mainly the result of higher purchased fuel
costs and expenses associated with the maintenance activities. Also contributing to the increase in expenses were operating costs to produce low-sulfur gasoline. Realized margins were slightly higher than the year-ago period ($10 million) with
higher margins in the MidContinent being partially offset by lower margins in the Northeast.

Retail Marketing broke even in the current quarter versus a loss of $8 million in the first
quarter of 2005. While retail gasoline margins were poor during most of the current quarter, there was a $7 million after-tax improvement versus the year-ago period. Monthly gasoline and diesel throughput per Company owned or leased outlet was
approximately the same versus the first quarter of 2005.

A Retail Portfolio Management (RPM) program is ongoing, which is selectively reducing
the Companys invested capital in Company-owned or leased sites. During the 2003-2006 period, selected sites are being divested. Most of the sites are being converted to contract dealers or distributors thereby retaining most of the gasoline
sales attributable to the divested sites within the Sunoco branded business. The Company expects to generate divestment proceeds of approximately $230 million, of which $180 million has been received through March 31, 2006 related to the sale
of 341 sites. During the first three months of 2006 and 2005, net after-tax gains of $3 and $2 million, respectively, were recognized in connection with the RPM program. The Company expects the RPM program will generate additional gains in 2006.

|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Chemicals earned $14 million in the first quarter of 2006 versus $33 million in the prior-year quarter. The $19 million
decrease in earnings was due primarily to lower margins for both phenol and polypropylene ($13 million) and higher expenses ($5 million), due in part to higher fuel and utility costs.

During the third quarter of 2005, an arbitrator ruled that Sunoco was liable in an arbitration proceeding for breaching a supply agreement concerning the prices charged to Honeywell International, Inc.
(Honeywell) for phenol produced at Sunocos Philadelphia chemical plant from June 2003 through April 2005. In January 2006, the arbitrator ruled that Sunoco should bill Honeywell based on the pricing formula established in the
arbitration until a second arbitration, set to begin in the second quarter of 2006, finalizes pricing for 2005 and beyond (see below). Damages of approximately $95 million, including prejudgment interest, were assessed, of which $27, $48 and $20
million pertained to 2005, 2004 and 2003, respectively. Such damages, which were paid to Honeywell in April 2006, have been reported as a charge against 2005 earnings and were shown separately as Phenol Supply Contract Dispute under Corporate and
Other in the Earnings Profile of Sunoco Businesses ($46 million after tax in the third quarter and $10 million after tax in the fourth quarter). In March 2006, a U.S. District Court judge upheld the arbitrators ruling. The phenol supply
agreement provides for a reopener for pricing on and after January 1, 2005 and sets forth specific standards for determining such pricing. The parties have been unsuccessful in negotiating the post-2004 price, and a new price will be determined
in a second arbitration to be held before a different arbitrator. Sunoco believes the basis for the post-2004 pricing is substantially different from the basis of the award in the first arbitration. (See Note 3 to the condensed consolidated
financial statements.)

Logistics

Sunocos
Logistics business earned $6 million in the first quarter of 2006 versus $3 million in the first quarter of 2005. The $3 million increase in earnings was due largely to the absence of a $3 million after-tax accrual attributable to a pipeline spill
in January 2005 and a $2 million unfavorable tax adjustment,

partially offset by Sunocos reduced ownership in the Partnership subsequent to the 2005 public offerings (see
Financial Condition  Other Cash Flow Information below).

In March 2006, the Partnership purchased two separate crude oil pipeline
systems and related storage facilities located in Texas, one from affiliates of Black Hills Energy, Inc. (Black Hills) for $41 million and the other from affiliates of Alon USA Energy, Inc. (Alon) for $68 million. The Black
Hills acquisition also includes a lease acquisition marketing business and related inventory. The Alon pipeline system is currently idled and is scheduled to be returned to service on June 1, 2006. The Partnership also expects to complete a $12
million project to expand capacity on the Alon pipeline system and to construct new tankage at the Nederland terminal to service these new volumes by the end of 2006. In August 2005, the Partnership completed the acquisition of another crude oil
pipeline system and related storage facilities located in Texas from ExxonMobil for $100 million. In December 2005, the Partnership also completed the acquisition of an ownership interest in the Mesa Pipeline from Chevron for $5 million, which
coupled with the 7.2 percent interest it acquired from Sunoco, gave it a 37.0 percent ownership interest. The above acquisitions were initially funded with proceeds from borrowings under the Partnerships revolving credit facility (see
Financial Condition  Financial Capacity below).

Coke

Coke earned $14 million in the first quarter of 2006 versus $10 million in the first quarter of 2005. The $4 million increase in earnings was due primarily to higher income from the cokemaking facility in Haverhill,
OH, which commenced operations in March 2005, lower selling, general and administrative expenses and slightly higher tax benefits from cokemaking operations despite a partial phase-out of the benefits as a result of the high level of crude oil
prices during the first quarter of 2006 (see below).

Under existing tax law, the coke production at Jewell and Indiana Harbor is not eligible to generate
nonconventional fuel tax credits after 2007, which is expected to result in a decline in Sun Cokes annual income of approximately $12 million on an after-tax basis beginning in 2008. The energy policy legislation enacted in August 2005
includes additional tax credits pertaining to a portion of the coke production at Jewell, all of the production at Haverhill and all future domestic coke plants placed into service by January 1, 2010. The new credits cover a four-year period,
effective January 1, 2006 or the date any new facility is placed into service, if later. Beginning in 2006, the new credits attributable to Sun Cokes existing Jewell and Haverhill facilities are expected to result in an increase in Sun
Cokes annual income of approximately $6 million after tax. However, prior to their expiration dates, all of the tax credits would be phased out, on a ratable basis, if the average annual price of domestic crude oil at the wellhead is within a
certain inflation-adjusted price range. (This range was $53.20 to $66.79 per barrel for 2005.) The domestic wellhead price averaged $56.84 per barrel for the two months ended February 28, 2006, $55.82 per barrel for the month of February 2006
and $50.26 per barrel for the year ended December 31, 2005. If the annual crude oil price averages at or above the top of the inflation-adjusted range during 2006 or 2007, then it is estimated the corresponding reduction in Sun Cokes
after-tax income would approximate $24 million for each year. Based upon the Companys estimate of domestic wellhead prices for the first quarter of 2006, Sun Coke recorded only 85 percent of the benefit of the tax credits that otherwise would
have been available without regard to these phase-out provisions. The estimated impact of the phase-out reduced earnings for the first quarter of 2006 by $1 million after tax. The ultimate amount of the credits to be earned during 2006 will be based
upon the average annual price of domestic crude oil at the wellhead. The above estimates incorporate increased coke prices resulting from the expiration or any phase out of the tax credits with respect to coke sold under long-term contracts from the

Indiana Harbor and Haverhill plants. The Company also could be required to make cash payments to the third-party
investors if the tax credit is reduced as a result of increased domestic crude oil prices. However, the Company currently does not believe that any such payments would be required. (See Note 2 to the condensed consolidated financial statements.)

In August 2004, Sun Coke entered into a series of agreements with two major steel companies (the Off-takers) with respect to the development
of a 1.7 million tons-per-year cokemaking facility and associated cogeneration power plant in Vitória, Brazil. Those agreements generally include: technology license agreements whereby Sun Coke has licensed its proprietary technology to
a project company (the Project Company); an engineering and technical services agreement whereby Sun Coke is providing engineering and constructionrelated technical services to the Project Company; an operating agreement whereby a
local subsidiary of Sun Coke will operate the cokemaking and water treatment plant facilities for a term of not less than 15 years; and an investment agreement by and among Sun Coke and the Off-takers whereby Sun Coke has acquired an initial one
percent equity interest in the Project Company and an option to purchase an additional 19 percent equity interest. Sun Coke expects to exercise this option in 2006 or 2007 for approximately $35 million. The Off-takers will purchase from the Project
Company all coke production under long-term agreements, and one of the Off-takers will purchase all of the electricity produced at the cogeneration power plant. Those off-take agreements are still to be negotiated. Construction of the facilities
commenced in November 2004 and the facilities are expected to be operational in the fourth quarter of 2006.

Sun Coke is currently discussing other
opportunities for developing new heat recovery cokemaking facilities with several domestic and international steel companies. Such cokemaking facilities could be either wholly owned or owned through a joint venture with one or more parties. The
steel company customers would be expected to purchase the coke production on a take-or-pay or equivalent basis.

Corporate and Other

Corporate Expenses  Corporate administrative expenses were $16 million after tax in both three-month periods.

Net Financing Expenses and Other  Net financing expenses and other were $12 million after tax in the first quarter of 2006 versus $14 million in the prior-year
quarter. The $2 million decline was primarily due to higher interest income ($4 million), partially offset by a decrease in capitalized interest ($3 million).

Analysis of Condensed Consolidated Statements of Income

Revenues  Total revenues were $8.59 billion in the first quarter of 2006 compared to $7.21 billion in the first quarter of 2005. The 19 percent increase was primarily due to higher refined product prices. An
increase in revenues due to higher crude oil sales in connection with the crude oil gathering and marketing activities of the Companys Logistics operations and higher consumer excise taxes was essentially offset by lower refined product sales
volumes.

Costs and Expenses  Total pretax costs and expenses were $8.46 billion in the current quarter compared to $7.01 billion in the first
quarter of 2005. The 21 percent increase was primarily due to higher crude oil acquisition costs resulting from price increases. Also contributing to the increase in total pretax costs and expenses were higher crude oil costs in connection with the
crude oil gathering and marketing activities of the Companys Logistics operations and higher consumer excise taxes.

FINANCIAL CONDITION

Cash and Working Capital

At
March 31, 2006, Sunoco had cash and cash equivalents of $361 million compared to $919 million at December 31, 2005, and had a working capital deficit of $670 million compared to a working capital deficit of $523 million at
December 31, 2005. The $558 million decrease in cash and cash equivalents was due to $313 million of net cash used in operating activities and a $270 million net use of cash in investing activities, partially offset by $25 million of net cash
provided by financing activities. Sunocos working capital position is considerably stronger than indicated because of the relatively low historical costs assigned under the LIFO method of accounting for most of the inventories reflected in the
condensed consolidated balance sheets. The current replacement cost of all such inventories exceeded their carrying value at March 31, 2006 by $2,477 million. Inventories valued at LIFO, which consist of crude oil, and petroleum and chemical
products, are readily marketable at their current replacement values. Management believes that the current levels of cash and working capital are adequate to support Sunocos ongoing operations.

Cash Flows from Operating Activities

In the first three months of 2006, Sunoco had a net use of cash in operating activities of $313 million compared to $247 million of net cash provided by operating activities (cash generation) in the first three months of 2005.
This $560 million decrease in cash generation was primarily due to an increase in working capital uses pertaining to operating activities. Also contributing to the decline in cash generation were the decrease in net income and the absence of $48
million of cash proceeds received in the first quarter of 2005 in connection with a power contract restructuring. The increase in working capital uses reflects an increase in crude oil inventories as a result of reduced crude oil inputs in
connection with refinery turnaround activity late in the first quarter. An increase in refined product inventories and incentive compensation payments to employees also contributed to the increase in working capital uses during the quarter.

Other Cash Flow Information

In the second quarter of 2005, the Partnership issued 2.8 million limited partnership units at a price of $37.50 per unit. Proceeds from the offering, net of underwriting discounts and offering expenses, totaled approximately $99
million. These proceeds were used to redeem an equal number of limited partnership units owned by Sunoco. In the third quarter of 2005, the Partnership issued an additional 1.6 million limited partnership units at a price of $39.00 per unit.
Proceeds from the offering, which totaled approximately $61 million, net of underwriting discounts and offering expenses, were used by the Partnership principally to repay a portion of the borrowings under its revolving credit facility.

As of March 31, 2006, Sunoco owned 12.06 million limited partnership units consisting of 6.37 million common units and 5.69 million subordinated
units. Distributions on Sunocos subordinated units are payable only after the minimum quarterly distributions of $.45 per unit for the common units held by the public and Sunoco, including any arrearages, have been made. The subordinated units
convert to common units if certain financial tests related to earning and paying the minimum quarterly distribution for the preceding three consecutive one-year periods have been met. In February 2006 and 2005, when the quarterly cash distributions
pertaining to the fourth quarters of 2005 and 2004 were paid, the first two three-year requirements were satisfied. As a result, a total of 5.70 million of Sunocos subordinated units have been converted to common units, 2.85

##### Table of Contents

million each in February 2006 and February 2005. If the Partnership continues to meet the financial tests through the
fourth quarter of 2006, all of Sunocos remaining 5.69 million subordinated units would be converted to common units in February 2007.

The
Partnerships issuance of common units to the public has resulted in an increase in the value of Sunocos proportionate share of the Partnerships equity as the issuance price per unit exceeded Sunocos carrying amount per unit
at the time of issuance. The resultant gain to Sunoco on these transactions, which totaled approximately $125 million pretax at March 31, 2006, has been deferred as a component of minority interest in the Companys condensed consolidated
balance sheets as the common units issued do not represent residual interests in the Partnership due to Sunocos ownership of the subordinated units. The deferred gain would be recognized in income when Sunocos remaining subordinated
units convert to common units at which time the common units become the residual interests.

Financial Capacity

Management currently believes that future cash generation will be sufficient to satisfy Sunocos ongoing capital requirements, to fund its pension
obligations (see Pension Plan Funded Status below) 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 including reductions in margins for products sold and increases in the levels of capital spending (including acquisitions) and working capital. During those periods, the Company may supplement its cash generation with proceeds
from financing activities.

The Company has a revolving credit facility (the Facility) totaling $900 million, which matures in August 2010. The
Facility provides the Company with access to short-term financing and is intended to support the issuance of commercial paper, letters of credit and other debt. The Company also can borrow directly from the participating banks under the Facility.
The Facility is subject to commitment fees, which are not material. Under the terms of the Facility, Sunoco is required to maintain tangible net worth (as defined in the Facility) in an amount greater than or equal to targeted tangible net worth
(targeted tangible net worth being determined by adding $1.125 billion and 50 percent of the excess of net income over share repurchases (as defined in the Facility) for each quarter ended after March 31, 2004). At March 31, 2006, the
Companys tangible net worth was $2.3 billion and its targeted tangible net worth was $1.4 billion. The Facility also requires that Sunocos ratio of consolidated net indebtedness, including borrowings of Sunoco Logistics Partners L.P., to
consolidated capitalization (as those terms are defined in the Facility) not exceed .60 to 1. At March 31, 2006, this ratio was .33 to 1. At March 31, 2006, the Facility was being used to support $103 million of floating-rate notes due
2034.

Sunoco Logistics Partners L.P. has a $300 million revolving credit facility, which matures in November 2010. This facility is available to fund the
Partnerships working capital requirements, to finance acquisitions, and for general partnership purposes. It includes a $20 million distribution sublimit that is available for distributions to third-party unitholders and Sunoco. At
March 31, 2006, $216 million was outstanding under this credit facility. During the first quarter of 2006, $109 million was drawn against the facility to fund the Partnerships March 2006 acquisition of two separate crude oil pipeline
systems and related storage facilities located in Texas. The Partnership recently commenced debt and equity offerings under its shelf registration statement (see below) to repay the borrowings under its credit facility, which had been used to fund
its previous acquisitions, and to fund additional growth capital opportunities. The credit facility contains convenants requiring the Partnership to maintain a ratio of up to 4.75 to 1 of its consolidated total debt to its consolidated EBITDA (each
as defined in the credit facility) and an interest coverage ratio (as defined in the credit facility) of at least 3 to 1. At March 31, 2006, the Partnerships ratio of its consolidated debt to its consolidated EBITDA was 3.4 to 1 and the
interest coverage ratio was 4.6 to 1.

Epsilon, the Companys consolidated joint venture, has a $40 million revolving credit facility that matures in
September 2006. The credit facility contains restrictive covenants which, among other things, limit the incurrence of additional debt and the sale of assets by Epsilon. At March 31, 2006, $6 million was outstanding under the credit facility.
Borrowings under this credit facility as well as Epsilons $120 million term loan that is also due in September 2006 are guaranteed by Sunoco, Inc.

Management believes there is sufficient financial capacity available to pursue strategic opportunities as they
arise. In addition, the Company has the option of issuing additional common or preference stock or selling an additional portion of its Sunoco Logistics Partners L.P. common units, and Sunoco Logistics Partners L.P. has the option of issuing
additional common units.

The Company has a shelf registration statement which provides the Company with financing flexibility to offer senior and
subordinated debt, common and preferred stock, warrants and trust preferred securities. At March 31, 2006, $1,050 million remains available under this shelf registration statement. Sunoco Logistics Partners L.P. also has a shelf registration
statement, under which the Partnership may sell up to a total of $500 million of debt or common units in primary offerings to the public, and Sunoco may sell up to a total of five million common units, which represent a portion of its limited
partnership interests in the Partnership, in secondary offerings to the public. In early May 2006, the Partnership commenced offerings utilizing its shelf registration statement under which it intends to issue $175 million of senior notes due 2016
and 2.4 million limited partnership units. The proceeds from these offerings, net of underwriting discounts and offering expenses, total approximately $272 million. Both offerings are expected to be completed on May 8, 2006. Upon
completion of the equity offering, Sunocos interest in the Partnership, including its 2 percent general partnership interest, is expected to decrease from 48 percent to 44 percent. The accounts of the Partnership will continue to be included
in Sunocos consolidated financial statements. The amount, type and timing of any future financings under these registration statements will depend upon, among other things, the Companys and Partnerships funding requirements, market
conditions and compliance with covenants contained in the Companys and Partnerships respective debt obligations and revolving credit facilities.

Off-Balance Sheet Arrangement

A
wholly owned subsidiary of the Company, Sunoco Receivables Corporation, Inc., is a party to an accounts receivable securitization facility that terminates in December 2006 under which the subsidiary may sell on a revolving basis up to a $200 million
undivided interest in a designated pool of certain of Sunocos accounts receivable. No receivables have been sold to third parties under this facility.

Capital Expenditures

The Company
previously announced that it expected capital expenditures over the 2006-2008 period in Refining and Supply would be approximately $1.9 billion, including $775 million for income improvement projects. The current status of these capital projects
ranges from the preliminary design and engineering phase to the

construction phase. Market conditions for engineering, procurement and construction of refinery projects have tightened
and the Company currently believes that the cost of these projects could be higher than originally anticipated and project completion dates could be extended. While the Company does not expect a significant change in the scope of its capital
program, continued deterioration of the project environment could result in the deferral of some lower-return projects.

In April 2006, the Company applied
for an air permit to initiate an alkylation process improvement project at its Philadelphia refinerys HF alkylation unit. The project will involve the incorporation of ReVAP technology which will require substantial improvements and
modifications to the alkylation unit and supporting utility systems and will increase production of alkylate. The overall project cost is approximately $61 million. The project is scheduled for completion during the first quarter of 2008 subject to
permit approval, fabrication and delivery of materials.

Management currently anticipates making $100 million of voluntary contributions to its funded defined benefit
plans in 2006. Management believes any additional contributions to the pension plans can be funded without a significant impact on liquidity. Future changes in the financial markets and/or interest rates could result in additional significant
increases or decreases to the accumulated other comprehensive loss component of shareholders equity and to future pension expense and funding requirements.

DIVIDENDS AND SHARE REPURCHASES

On July 7, 2005, the Companys Board of Directors (Board) approved a
two-for-one split of Sunocos common stock to be effected in the form of a stock dividend. The shares were distributed on August 1, 2005 to shareholders of record as of July 18, 2005. In connection with the common stock split, the
number of authorized shares of common stock was increased from 200 million to 400 million, and the shares of common stock reserved for issuance pertaining to Sunocos 63/4percent convertible debentures and various employee benefit plans were proportionally increased in accordance with the terms of those respective
agreements and plans. Share and per-share data (except par value) presented for all periods reflect the effect of the stock split.

The Company
increased the quarterly cash dividend paid on common stock from $.15 per share ($.60 per year) to $.20 per share ($.80 per year) beginning with the second quarter of 2005 and then to $.25 per share ($1.00 per year) beginning with the second quarter
of 2006. The estimated $33 million dividend for the second quarter of 2006 has been reflected as a reduction in earnings employed in the business at March 31, 2006.

FORWARD-LOOKING STATEMENTS

Some of the information included in this quarterly report on Form 10-Q contains forward-looking statements
(as defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934). These forward-looking statements discuss estimates, goals, intentions and expectations as to future trends, plans, events,
results of operations or financial condition, or state other information relating to the Company, based on current beliefs of management as well as assumptions made by, and information currently available to, Sunoco. Forward-looking statements

possible, potential, predict, project, scheduled, should, or other similar words, phrases or expressions that convey the uncertainty of future events or outcomes. Although
management 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, without limitation:

effects on the Company. All forward-looking statements included in this Form 10-Q are expressly qualified in their entirety by the foregoing cautionary statements. The Company undertakes no obligation to update publicly any forward-looking statement
(or its associated cautionary language) whether as a result of new information or future events.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to the
Companys exposure to market risk since December 31, 2005.

Item 4. Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, as of the end of the
period covered by this report, the Company carried out an evaluation of the effectiveness of the design and operation of the Companys disclosure controls and procedures. This evaluation was carried out under the supervision and with the
participation of the Companys management, including the Companys Chairman, Chief Executive Officer and President and the Companys Senior Vice President and Chief Financial Officer. Based upon that evaluation, the Companys
Chairman, Chief Executive Officer and President and the Companys Senior Vice President and Chief Financial Officer concluded that the Companys disclosure controls and procedures are effective.

Disclosure controls and procedures are designed to ensure that information required to be disclosed in Company reports filed or submitted under the
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures
designed to ensure that information required to be disclosed in Company reports filed under the Exchange Act is accumulated and communicated to management, including the Companys Chairman, Chief Executive Officer and President and the
Companys Senior Vice President and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

There have been no changes in the Companys internal control over financial reporting during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Companys internal
control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

In June 2005, Sunoco, Inc. (R&M), a subsidiary of Sunoco, Inc., reached a
global settlement relating to its refineries with the U.S. Environmental Protection Agency (EPA), and the Pennsylvania Department of Environmental Protection (PADEP), the City of Philadelphia Office of Air Management Services
(AMS), the Ohio Environmental Protection Agency (OEPA), and the Oklahoma Department of Environmental Quality (ODEQ). (See the Companys Quarterly Report on Form 10-Q for the quarterly period ended
June 30, 2005.) The Consent Decree concerning this settlement was lodged with the U.S. District Court for the Eastern District of Pennsylvania in June 2005, and was entered by the Court in March 2006. Under the Consent Decree it is anticipated
that Sunoco will make capital expenditures of approximately $275 million over an eight-year period in connection with the implementation of environmental improvement projects. In addition, Sunoco has paid civil penalties aggregating $3 million to
the EPA and the state and local agencies, and has committed to supplemental environmental projects of approximately $3.9 million. (See the Companys Annual Report on Form 10-K for the fiscal year ended December 31, 2005.)

Many other legal and administrative proceedings are pending or possible against Sunoco from its current and past operations, including proceedings related
to commercial and tax disputes, product liability, antitrust, employment claims, leaks from pipelines and underground storage tanks, natural resource damage claims, premises-liability claims, allegations of exposures of third parties to toxic
substances (such as benzene or asbestos) and general environmental claims. 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 that may arise from such proceedings would not be material in relation to Sunocos business or consolidated financial position at March 31, 2006.

Item 1A. Risk Factors

There have been no material changes to the risk factors faced by the Company since
December 31, 2005.
