                         REPORT OF INDEPENDENT AUDITORS

Plan Administrator
Sunoco, Inc. Capital Accumulation Plan

We have audited the accompanying statements of assets available for benefits of
the Sunoco, Inc. Capital Accumulation Plan (Plan) as of December 31, 2001 and
2000, and the related statements of changes in assets available for benefits for
the years then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
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 basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the assets available for benefits of the Plan at December
31, 2001 and 2000 and the changes in its assets available for benefits for the
years then ended, in conformity with accounting principles generally accepted in
the United States.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental Schedule of
Assets (Held at End of Year) as of December 31, 2001 is presented for purposes
of additional analysis and is not a required part of the financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                     SUNOCO, INC. CAPITAL ACCUMULATION PLAN
                          NOTES TO FINANCIAL STATEMENTS

1.   GENERAL DESCRIPTION

     The Sunoco, Inc. Capital Accumulation Plan (Plan) is a combined
     profit-sharing and employee stock ownership plan. The Plan provides
     eligibility for membership for certain employees of Sunoco, Inc. and its
     participating subsidiary companies (collectively, Sunoco) who have
     completed at least 1,000 hours of service with Sunoco in a twelve-month
     period. An eligible employee can join the Plan at any time starting with
     the first payroll period which begins on or next following the day after he
     or she gives written notice to the Plan Administrator. The ESOP Fund is an
     employee stock ownership plan, while the remaining funds form a
     profit-sharing plan.

     The Plan provides an individual account for each participant. Amounts
     disbursed to participants or transferred among funds are based solely upon
     amounts contributed to each participant's account adjusted to reflect any
     withdrawals and distributions, investment earnings attributable to such
     account balances, and appreciation or depreciation of the market value of
     the account balance.

     Contributions:

     In general, a participant may make Basic Contributions to the Plan of up to
     5% in whole percentages of base pay on a pre-tax basis (Basic Pre-Tax
     Contributions) or on a post-tax basis (Basic Post-Tax Contributions). The
     participant also may elect to make additional contributions up to 10% of
     base pay provided, however, that Basic Pre-Tax or Basic Post-Tax
     Contributions are at least 5% of base pay. The additional 10% may be
     contributed either on a pre-tax basis (Additional Pre-Tax Contributions),
     post-tax basis (Additional Post-Tax Contributions) or any combination
     thereof. For certain participants, limitations imposed by the Internal
     Revenue Code of 1986, as amended (Code), as described below, restrict their
     ability to make Basic Pre-Tax Contributions or Additional Pre-Tax
     Contributions. However, such participants may make Basic Post-Tax
     Contributions and Additional Post-Tax Contributions such that the sum of
     their total and employer contributions do not exceed other limits imposed
     by the Plan or the Code.

     For every dollar a participant contributes as Basic Contributions, Sunoco
     contributes another full dollar (Matching Employer Contributions).

     Pre-tax contributions by each participant may not exceed an annual limit
     which is determined under Internal Revenue Service (IRS) regulations. This
     limit was $10,500 for both 2001 and 2000.

                                       3



                     SUNOCO, INC. CAPITAL ACCUMULATION PLAN
                    NOTES TO FINANCIAL STATEMENTS (Continued)

1.   GENERAL DESCRIPTION (Continued)

     The pre-tax contributions and combined Basic Post-Tax Contributions,
     Additional Post-Tax Contributions and Matching Employer Contributions of
     participants who come within the classification of "highly compensated
     employees" as defined in the Code, may not exceed certain technical limits
     under the Code. Generally, the allowable percentage of such contributions
     for the highly compensated employees is dependent upon the percentage of
     contributions made by all other employees. These limitations may have the
     effect of reducing the level of contributions initially selected by the
     highly compensated employees. In addition, the total employer and employee
     contributions which may be allocated to a participant's account may be
     limited by Section 415 of the Code.

     The Plan contains a special provision designed to permit the Plan to borrow
     money to purchase a significant number of shares of Sunoco Common Stock.
     Such borrowing could only occur upon the action of the Board of Directors
     of Sunoco, Inc. If this should occur, the securities purchased with the
     proceeds of such a loan will not be allocated immediately to the accounts
     of Plan participants but will be held by the Plan in an unallocated
     suspense account. Securities will be released from the suspense account as
     the loan is repaid and will be allocated to participants' accounts
     according to the ratio which the participant's compensation bears to the
     compensation of all participants in the Plan. No participant contributions
     will be required or permitted in paying off the loan. Further, subject to
     applicable limitations imposed by Section 415 of the Code and limitations
     on allocations as set forth in the Plan, any securities which are allocated
     to participants' accounts as a result of the repayment of the loan may, at
     the discretion of the Plan Administrator, be used to satisfy Sunoco's
     obligation with respect to any Matching Employer Contributions. As of
     December 31, 2001, no borrowings had been approved.

     A participant's account is credited daily with units representing interests
     held in each of the funds described below except for the Personal Choice
     Retirement Account (PCRA) Fund. A participant's account balance is
     immediately 100% vested.

     Investment Alternatives:

     Deutsche Bank is the Trustee for all investments. The participant has the
     option of investing in any one or more of six core investment funds
     (collectively, the Core Funds) (the Equity Index Fund; the U.S. Extended
     Market Equity Fund; the International Equity Fund; the Diversified
     Investments Fund; the Capital Preservation Fund; and the Sunoco Common
     Stock Fund) and the Personal Choice Retirement Account (PCRA) Fund. For all
     funds except the PCRA Fund, participants' accounts earn a blended rate, or
     weighted average, of all of the investments held in the respective funds.
     These seven funds and the ESOP Fund are currently invested in corresponding
     funds with the same investment objectives in the Sunoco, Inc. Defined
     Contribution Master Trust (Master Trust). The Master Trust also includes
     investments from other Sunoco tax-qualified defined contribution plans.
     Except for the PCRA Fund, each plan's relative interest in the individual
     Master Trust funds and the related income

1.   GENERAL DESCRIPTION (Continued)

     and administrative expense is determined on a basis proportionate to each
     plan's past contributions adjusted to reflect distributions, transfers and
     prior investment earnings to such funds.

     The PCRA investments are held in separate accounts for each participant. If
     a participant wants to transfer an amount to the PCRA Fund, at a minimum,
     the greater of $1,000 or 10 percent of his account balance must remain
     invested in the Core Funds. Actual income, losses and investment expenses
     associated with PCRA investments are recorded directly in the respective
     participants' accounts.

     The following table sets forth each fund's respective share of the total
     net assets of the corresponding Master Trust fund at December 31, 2001 and
     2000:

     At December 31, 2001 and 2000, the Capital Preservation Fund of the Master
     Trust is principally invested in both synthetic and standard investment
     contracts.

     The synthetic investment contracts are currently with Bank of America, CDC
     Capital, Inc. (formerly CDC Financial Products, Inc.), Monumental Life
     Insurance Company, National Westminster Bank plc, Rabobank Nederland,
     Transamerica Life Companies and Westdeutsche Landesbank Giroentrale. They
     are composed of underlying assets and "wrappers", which are contracts that
     enable withdrawals to be made at contract value, rather than at the market
     value of the underlying assets. The contracts have underlying assets
     invested either directly or through collective trust funds in government
     agency-backed collateralized mortgage obligation issues, government and
     corporate bonds and other asset-backed securities. The contracts are
     presented below in two separate portfolios based upon the investment
     strategy for the underlying assets. The assets in the "Buy and Hold
     Portfolios" are expected to be held until maturity, while the "Managed
     Portfolios" are actively managed to reflect changing market conditions.
     Interest crediting rates for these contracts are reset at least quarterly,
     as specified in the respective contracts.

     trust funds (4% and 9%) maintained by Barclay's Global Investors. The
     collective trust funds are comprised primarily of U.S. government-backed
     and agency obligations and short-term investments.

     Over time, the contracts will earn the rate of return of the underlying
     assets.

     The Plan's relative interest in the standard investment contracts with
     insurance companies or other financial institutions described above
     represents the maximum potential credit losses from concentrations of
     credit risk in the Capital Preservation Fund in accordance with the
     provisions of Statement of Financial Accounting Standards No. 107,
     "Disclosures about Fair Value of Financial Instruments" (SFAS No. 107).
     SFAS No. 107 requires that such potential credit losses be determined
     assuming (1) complete nonperformance by the counterparties to the
     transactions and (2) any related collateral has no value. There is no
     collateral associated with the standard investment contracts in the Capital
     Preservation Fund. Plan management believes that future credit losses of
     the Plan's investment in the Capital Preservation Fund of the Master Trust,
     if any, would not be material in relation to the Capital Preservation
     Fund's net assets available for benefits at December 31, 2001. There are no
     other significant concentrations of credit risk in other Plan assets.

1.   GENERAL DESCRIPTION (Continued)

     The average interest crediting rates at December 31, 2001 and 2000 for all
     synthetic and standard investment contracts in the aggregate were 5.75% and
     6.38%, respectively. The average yields for the years ended December 31,
     2001 and 2000 for such contracts in the aggregate were 5.97% and 6.54%,
     respectively.

     Employers' Contributions:

     Employer contributions are invested in each of the funds in the same
     proportion as the participant's contributions are invested in such funds.

     Investment Earnings Reinvestment/Distribution:

     Earnings from dividends and interest in all funds (except the ESOP Fund and
     the PCRA Fund) are retained by the Trustee and reinvested in the same fund.
     A participant who has funds in the ESOP Fund may elect to receive a payment
     equal to the dividends due on all Sunoco Common Stock attributable to his
     or her account in the ESOP Fund (dividend equivalents) if they exceed $10.
     Dividends on Sunoco Common Stock in the ESOP Fund for which a participant
     has not elected to receive an equivalent distribution, or which are not
     eligible for payment, are credited to his or her account in the ESOP Fund
     and are reinvested in Sunoco Common Stock by the Trustee. Earnings from
     dividends and interest in the PCRA Fund are invested in short-term
     investments that are credited directly to the participant's account.

     Rollovers, Withdrawals and Transfers:

     Certain employees of Sunoco may roll over the taxable portion of a
     distribution from a tax-qualified plan of a previous employer into the
     Plan, provided certain conditions imposed by the Plan Administrator are
     met. Such transfers are separately reflected in the statements of changes
     in assets available for benefits (Note 3).

     Employees who terminate employment and elect to defer the distribution of
     their Plan account may also directly roll over the taxable portion of
     distributions from other Sunoco tax-qualified plans into the Plan.

     Upon retirement or other termination of employment, the balances credited
     to a participant's account will be held in the Plan until the participant
     reaches age 70 1/2, unless the participant elects an earlier distribution.
     However, if the participant is still employed at age 70 1/2, the balances
     will be distributed at retirement. Alternatively, a participant who
     terminates service may request that the account balance be transferred
     directly to an individual retirement account or annuity or a defined
     contribution plan maintained by a successor employer. Retirees or
     terminated vested persons, regardless of age, may elect to take periodic
     distributions either through withdrawals every six months in varying
     amounts or in substantially equal payments every six months over the
     participant's remaining life expectancy.

1.   GENERAL DESCRIPTION (Continued)

     A participant, during employment, may withdraw up to 100% of Matching
     Employer Contributions, including any earnings thereon, and his ESOP
     sub-account under the ESOP Fund, if any, provided that such contributions
     have been in the Plan for two years. In addition, a participant may
     withdraw up to 100% of Additional Post-Tax Contributions including any
     earnings thereon. Withdrawals are permitted once every six months.

     Withdrawals from the Equity Index Fund, U.S. Extended Market Equity Fund,
     International Equity Fund and Diversified Investments Fund are made in cash
     only while those from the Capital Preservation Fund may be made in cash or
     as an annuity. Withdrawals from the Sunoco Common Stock Fund and the ESOP
     Fund are made in the form of Sunoco Common Stock or cash at the
     participant's discretion. Withdrawals of Sunoco Common Stock are valued at
     the closing market prices on the last business day of the week in which the
     notice of withdrawal has been processed by the Plan. Withdrawals will be
     distributed from participants' accounts in the following order:

               Capital Preservation Fund
               Diversified Investments Fund
               Equity Index Fund
               U.S. Extended Market Equity Fund
               International Equity Fund
               Sunoco Common Stock Fund
               ESOP Fund

     Account balances in the PCRA Fund cannot be withdrawn directly.
     Participants must first liquidate investments held in the PCRA Fund and
     transfer sufficient proceeds to one of the other investment funds from
     which the withdrawal or a loan to the participant (see below) can be made.

     While actively employed, a participant generally is not entitled to
     withdraw Basic Pre-Tax Contributions, Basic Post-Tax Contributions or
     Additional Pre-Tax Contributions, including earnings thereon.

     A participant may transfer investments among all funds (except the Loan
     Fund), subject generally to the following rules. A participant may elect to
     change the investment allocation percentage for any fund (except the Loan
     Fund or PCRA Fund) or elect to transfer a specified dollar amount from the
     Equity Index Fund, U.S. Extended Market Equity Fund, International Equity
     Fund, Diversified Investments Fund, Capital Preservation Fund and PCRA Fund
     or share equivalents from the Sunoco Common Stock and ESOP Funds. Transfers
     or changes in fund allocation percentages may be made daily.

     Should total withdrawals or transfers from a fund during a month cause the
     Trustee to liquidate securities, resulting in a gain or loss to the fund,
     such gain or loss will be allocated, pro rata, among the participants who
     made such withdrawals or transfers during that month.

     Notwithstanding the foregoing, benefit payments shall be made in accordance
     with the Code and IRS regulations and shall be made to a participant and/or
     his or her designated beneficiary not later than April 1 of the calendar
     year following the calendar year in which the participant attains 70 1/2
     years of age or, if employed at age 70 1/2, at retirement.

                    NOTES TO FINANCIAL STATEMENTS (Continued)

1.   GENERAL DESCRIPTION (Continued)

     Loans to Participants

     The Plan Administrator has the authority, at his sole discretion, to direct
     the Trustee to lend a participant an amount not exceeding certain portions
     of the participant's account balance in the Plan. Participants are eligible
     to borrow if they are on the active payroll of Sunoco and have a Plan
     account balance of at least $2,000. The minimum loan amount is $1,000,
     while the maximum loan amount is the lesser of (a) $50,000 adjusted
     downward by the highest outstanding loan balance in the past twelve months
     or (b) one-half the value of the participant's account balance.
     Participants are permitted to borrow only once in a twelve-month period and
     to have no more than two loans outstanding at any time. Loan proceeds are
     withdrawn from each fund in which the participant has an account balance
     (except for the PCRA Fund) on a pro rata basis and are not taxable to the
     participant when received. Any loan which is not repaid according to its
     terms is in default and the outstanding loan balance (including accrued
     interest thereon) is treated as a distribution from the Plan. Loans may be
     prepaid in full but only after they have been outstanding for at least six
     months. Loans are reflected in the accompanying statements of assets
     available for benefits. As loans receivable (including interest thereon)
     are repaid, amounts are transferred into the funds in the same proportion
     as the participant's current contributions.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates:

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States requires management to
     make estimates and assumptions that affect the amounts reported in the
     financial statements and accompanying notes. Actual amounts could differ
     from these estimates.

     Investments:

     The valuation of the Plan's interests in collective trust funds or its
     relative interest in such funds held by the Master Trust is based on the
     closing market price on the last business day of the year of the assets
     held in the funds; the Plan's relative interest in such funds is determined
     by the Trustee on a unit-method basis. The Plan's relative interest in
     investments in both synthetic and standard investment contracts with
     insurance companies or other financial institutions held by the Master
     Trust are stated at contract value. Contract value represents contributions
     made under the contract plus interest accrued at the contract rate less any
     withdrawals. Synthetic investment contracts earn interest at rates that are
     reset at least quarterly as specified in the respective contract while
     standard investment contracts earn interest at fixed rates or variable
     rates that are reset at least quarterly. The Master Trust's management
     believes that the contract value of all of its investment contracts
     approximates fair value. However, since there is no significant secondary
     market for these investments, contract value may not be indicative of
     amounts

                                       12

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     that could be realized in a current market exchange. The valuation of
     Sunoco Common Stock is based on the closing market price reported on the
     New York Stock Exchange on the last business day of the Plan year.
     Investments held in the PCRA Fund are valued at their closing market prices
     on the last business day of the Plan year.

     Purchases and sales of securities are reflected on a trade-date basis.
     Dividend income is reported on the ex-dividend date; interest income is
     recorded as earned on an accrual basis. The net appreciation (depreciation)
     in the fair value of investments, which consists of realized gains (losses)
     and unrealized appreciation (depreciation), is reported as a component of
     the increase (decrease) in value of participation in the Sunoco, Inc.
     Defined Contribution Master Trust (Note 4).

     Benefits Paid to Participants:

     Benefits paid to participants, which include withdrawals and distributions,
     are recorded upon distribution.

     Administrative Expenses:

     All brokerage fees, taxes and other expenses related to the purchase and
     sale of securities in all funds are paid out of the respective assets of
     such funds. All other costs and expenses (other than the cost of services
     provided by Sunoco employees which are paid by Sunoco) incurred in
     administering the Plan are generally charged, pro rata, to each of the
     respective funds (except the PCRA Fund). Participants with investments in
     the PCRA Fund are charged a separate administrative fee which is deducted
     from their Core Fund investments.

3.   Transfers from Aristech Savings Plan

     On August 17, 2001, the Aristech Savings Plan, a defined contribution plan
     sponsored by Aristech Chemical Corporation, an indirect wholly owned
     subsidiary of Sunoco, Inc., was merged into the Plan. In connection with
     the merger, $38,098,158 of assets were transferred into the Plan.

5.   INCOME TAX STATUS

     The Plan has received a determination letter from the Internal Revenue
     Service dated September 16, 1995, stating that the Plan is qualified under
     Section 401(a) of the Internal Revenue Code and, therefore, the related
     trust is exempt from taxation. Once qualified, the Plan is required to
     operate in conformity with the Code to maintain its qualification. The Plan
     Administrator believes the Plan is being operated in compliance with the
     applicable requirements of the Code and, therefore, believes that the Plan
     is qualified and the related trust is tax exempt.
