REPORT OF INDEPENDENT AUDITORS To the Participants and the Plan Administrative Committee of the Harsco Corporation Savings Plan: In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the Harsco Corporation Savings Plan (the "Plan") at December 31, 2002 and 2001, and the changes in net assets available for benefits for the year ended December 31, 2002 in conformity with accounting principles generally accepted in the United States of America. 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 of these statements in accordance with auditing standards generally accepted in the United States of America, which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for the purpose of additional analysis and is not a required part of the basic 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 the 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.

NOTES TO FINANCIAL STATEMENTS ----------------------------- 1. General Description of Plan: ---------------------------- The following description of the Harsco Corporation Savings Plan (the "Plan") provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. The Plan is a defined contribution plan designed to comply with the requirements of the Employee Retirement Income Security Act of 1974 ("ERISA") and with the requirements for qualification under Sections 401(a) and 401(k) of the Internal Revenue Code (the "Code"). All U.S. employees (including officers) who receive a stated weekly, hourly, monthly, or annual rate of compensation and are employed by Harsco Corporation (the "Company") or any subsidiary of either the Company or a subsidiary which adopts this Plan with the approval of the Company shall be covered by, or remain covered by this Plan, are deemed "Eligible Employees." Also eligible are employees covered by a collective bargaining agreement where the agreement provides for the employees' eligibility to participate in the Plan. New employees deemed Eligible Employees under this Plan are eligible to participate in the Plan as of the first payroll of January, April, July or October after the date of hire. To participate in the Plan, an Eligible Employee must elect to contribute to the Plan through payroll deductions each pay period. Contributions are in whole percentages from 1% to 75% of compensation received for services as an employee of the Company or any subsidiary of the Company. The participant shall designate what percentage of such contributions will be "Pre-Tax Contributions" and what percentage will be "After-Tax Contributions." A participant who makes Matched Pre-Tax and/or Matched After-Tax Contributions in an aggregate amount of 6% of his or her compensation may also elect to contribute from 1% to 69% of his or her compensation as an Unmatched Pre-Tax Contribution and from 1% to 16% of his or her compensation as an Unmatched After-Tax Contribution, subject to IRS and Plan limitations. In no event during the year may (a) Matched Pre-Tax and Matched After-Tax Contributions exceed 6% of compensation, (b) Unmatched Pre-Tax and Unmatched After-Tax Contribution exceed 69% of compensation or (c) Pre-Tax Contributions exceed the amount specified by the Internal Revenue Service (IRS) code which was $11,000 and $10,500 for the years ended December 31, 2002 and 2001, respectively, for participants under 50 years of age. For participants who turned 50 on or before December 31, 2002, the pretax limit was $12,000 in 2002 as a result of an additional $1,000 of "catch-up contributions" allowed by law. Pre-Tax Contributions shall constitute a reduction in the participant's taxable income for purposes of Section 401(k) of the Code. After-Tax Contributions will be considered to be the participant's contributions to the Plan and shall not constitute a reduction in the participant's taxable income for the purposes of Section 401(k) of the Code. -6-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 1. General Description of Plan: (continued) ---------------------------------------- Pursuant to the Plan, the Company will make contributions in cash to the trustee for the account of each participant in an amount equal to 50% of the first 6% of such participant's compensation designated as Matched Pre-Tax Contributions and/or Matched After-Tax Contributions. These contributions are referred to as "Company Matching Contributions". Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's Matching Accounts is based on years of vesting service. A participant is 100% vested after three years of credited service. The Company pays administrative fees related to maintaining the Plan as a whole. Fees for investment management are subtracted from fund performance reported by each fund. Participant directed investment fund change fees and Plan record keeping fees are paid by the Company. Loan setup fees are paid by the participant. Effective January 1, 2003, account balances in Vanguard Institutional Index Fund will be assessed an annual 0.25% fee, assessed in quarterly increments, to cover record keeping expenses for the fund. Also effective January 1, 2003, transfers in and out of the Harsco Stock Fund will be assessed a $0.03 commission per share transferred. Participants may borrow from their fund accounts a minimum of $500 to a maximum of 50% of their vested account balance, not to exceed $50,000. Loan transactions are treated as a transfer to (from) the respective investment fund(s) from (to) the Participant Loans fund. The participant may choose the loan repayment period, not to exceed five years. However, the term may be for any period not to exceed 15 years if the purpose of the loan is to acquire the participant's principal residence. The loans are collateralized only by the portion of the participant's account from which the loan is made and bear interest at a rate commensurate with local prevailing rates as determined periodically by the Plan administrator. Interest rates on outstanding loans, based on the trustee's prime rate plus one percent, ranged from 5.25% to 10.5% at December 31, 2002. Principal and interest is paid ratably through payroll deductions. On termination of service due to death, disability, or retirement, a participant or beneficiary may elect one of three options. The participant or beneficiary may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account; a portion paid in a lump-sum, and the remainder paid later; or annual installments over not more than fifteen years. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. -7-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 1. General Description of Plan: (continued) ---------------------------------------- While the Company has not expressed any intent to discontinue the Plan, it reserves the right to terminate the Plan at any time or discontinue contributions thereunder. In the event such discontinuance resulted in the termination of the Plan, the accounts of each affected employee who has not yet incurred a break in service shall be fully vested. Complete distributions or withdrawals would be distributed to Plan participants and beneficiaries in proportion to their respective account balances. 2. Summary of Significant Accounting Policies: ------------------------------------------- Basis of Accounting: -------------------- The financial statements of the Plan are prepared under the accrual basis of accounting. Investment Valuation: --------------------- The Harsco Corporation Common Stock is stated at market value, which represents the closing price of the stock on the Composite Reporting Tape of the stock exchanges on the last day of trading of the calendar year. Shares in the Ariel Appreciation Fund, Dodge & Cox Stock Fund, Morgan Stanley Institutional Fund, Inc. U.S. Real Estate Fund, Neuberger Berman Genesis Fund, PIMCO Total Return Fund, Putnam Asset Allocation - Balanced Portfolio, Putnam Asset Allocation - Conservative Portfolio, Putnam Asset Allocation - Growth Portfolio, Putnam Bond Index Fund, Putnam Fund for Growth and Income, Putnam Income Fund, Putnam International Growth Fund, Putnam Money Market Fund, Putnam New Opportunities Fund, Putnam Voyager Fund, and Vanguard Institutional Index Fund, are all stated at fair value, which represents the closing price on the last day of trading of the calendar year. Cash, which represents funds held until purchases of common stock are completed, is stated at fair value. Participant loans are valued at cost which approximates fair value. Use of Estimates: ----------------- The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates. Other: ------ The Plan presents in the Statement of Changes in Net Assets Available for Benefits the net appreciation (depreciation) in the market value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. -8-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 2. Summary of Significant Accounting Policies: (continued): -------------------------------------------------------- The purchase and sale of investments are recorded on a trade-date basis. Dividend income is recorded on the ex-dividend date. Income from other investments is recorded as earned on an accrual basis. Both participant and Company contributions are accrued in the period of the related payroll deductions. Forfeitures, a result of participant withdrawals prior to their full vesting in the Plan, are used to reduce the amount of future Company matching contributions. 3. Investment Options: ------------------- The Plan, comprised of participant and Company contributions, contains the following investment options: (1) Harsco Common Stock Fund - (consisting of Common Stock purchased with Company and participant directed contributions): a fund consisting of Common Stock of Harsco Corporation purchased in the open market or through privately negotiated transactions to the extent permitted by rules of the New York Stock Exchange and the Securities and Exchange Commission. (2) Ariel Appreciation Fund - (consisting of investments purchased with participant directed contributions): a long-term growth oriented fund consisting primarily of medium sized company stocks. (3) Dodge & Cox Stock Fund - (consisting of investments purchased with participant directed contributions): a fund consisting principally of common stock with a primary objective of long-term growth and income. The fund's secondary objective is to achieve a reasonable current income. (4) Morgan Stanley Institutional Fund, Inc. U.S. Real Estate Fund - (consisting of investments purchased with participant directed contributions): a fund consisting primarily of equity securities of companies in the U.S. real estate industry, including real estate investment trusts. The fund seeks to provide above average current income and long-term capital appreciation. (5) Neuberger Berman Genesis Fund - (consisting of investments purchased with participant directed contributions): a fund consisting mainly of common stock of small capitalization companies that offer potential for capital growth. (6) PIMCO Total Return Fund - (consisting of investments purchased with participant directed contributions): a fund consisting, under normal circumstances, of at least 65% of its assets in a diversified portfolio of fixed income instruments of varying maturities. The fund seeks maximum total returns, consistent with preservation of capital and prudent investment management. -9-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 3. Investment Options: (continued): -------------------------------- (7) Putnam Asset Allocation - Balanced Portfolio - (consisting of investments purchased with participant directed contributions): a fund consisting of 45 - 75% investments in stocks and 25 - 55% investments in a diversified portfolio of fixed-income securities, including both government and corporate bonds. (8) Putnam Asset Allocation - Conservative Portfolio - (consisting of investments purchased with participant directed contributions): a fund consisting of 15 - 45% investments in stocks and 55 - 85% investments in a diversified portfolio of fixed-income securities, including both government and corporate bonds. (9) Putnam Asset Allocation - Growth Portfolio - (consisting of investments purchased with participant directed contributions): a fund consisting of 65 - 95% investments in stock that Putnam Management believes have the potential for capital appreciation and consisting of 5 - 35% investments in a diversified portfolio of fixed-income securities, including both government and corporate bonds. (10) Putnam Bond Index Fund - (consisting of investments purchased with participant directed contributions): a fund consisting of a sample of securities included in the Lehman Brothers Aggregate Bond Index. The fund's goal is to achieve a return, before the assessment of any fees, that closely approximates the index. (11) Putnam Fund for Growth and Income - (consisting of investments purchased with participant directed contributions): a fund consisting primarily of common stocks located mainly in the United States that offer potential for capital growth, current income, or both. (12) Putnam Income Fund - (consisting of investments purchased with participant directed contributions): a fund consisting principally of investments in bonds and other debt securities. Bonds include both corporate and government bonds. (13) Putnam International Growth Fund - (consisting of investments purchased with participant directed contributions): a growth oriented fund consisting of investments in a diversified portfolio of stocks of companies located mainly outside the United States. (14) Putnam Money Market Fund - (consisting of investments purchased with participant directed contributions): a fund consisting of short-term high-quality money market securities. Investments in this fund are neither insured nor guaranteed by the U.S. government. -10-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 3. Investment Options: (continued) ------------------------------- (15) Putnam New Opportunities Fund - (consisting of investments purchased with participant directed contributions): a fund consisting primarily of investments in common stock of U.S. companies within certain industry groups that Putnam management believes offer above-average long-term growth potential. (16) Putnam Voyager Fund - (consisting of investments purchased with participant directed contributions): a fund consisting mainly of investments in stock of midsized to large companies expected to grow over time. The fund invests all or a portion of its assets in companies located mainly inside the United States. (17) Vanguard Institutional Index Fund - (consisting of investments purchased with participant directed contributions): a fund consisting of investments in the same stocks and in substantially the same percentages as the S&P 500 Index. The Plan provides for various investment options as described above. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect participants' account balances and the amounts reported in the statement of net assets available for plan benefits and the statement of changes in net assets available for plan benefits. There were 5,250 participants at December 31, 2002 who participated in one or more of the 17 investment funds. At December 31, 2002 the number of participants selecting each of the investment funds for their contributions was as follows: Harsco Corporation Common Stock Fund.................. 4,981 Ariel Appreciation Fund............................... 35 Dodge & Cox Stock Fund................................ 48 Morgan Stanley Institutional Fund, Inc.

Investment Options: (continued): -------------------------------- The following table separately identifies those investments which represent five percent or more of the Plan's net assets at December 31, 2002 with comparable information for 2001: (in thousands) December 31 December 31 2002 2001 --------- --------- Harsco Corporation Common Stock (1) $ 75,014 $ 86,403 Participant Loans 10,005 9,554 Putnam Money Market Fund 23,242 19,661 Putnam Voyager Fund 13,141 19,648 Vanguard Institutional Index Fund 19,834 23,815 Other 42,067 39,493 --------- --------- $ 183,303 $ 198,574 ========= ========= (1) Harsco Corporation Common Stock includes $31,913 at December 31, 2002 and $36,521 at December 31, 2001 that is non-participant directed The following table summarizes the change in the non-participant directed portion of the Harsco Corporation Common Stock Fund: Balance at January 1, 2002 $ 36,521 Net depreciation in fair value (3,131) Contributions (net of forfeitures) 3,221 Termination payments (3,427) Transfers to participant directed investments (1,271) --------- Balance at December 31, 2002 $ 31,913 ========= -12-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 4. Related-Party Transactions: --------------------------- Certain Plan investments are shares of mutual funds managed by Putnam Investments. Putnam Investments is the trustee as defined by the Plan, and therefore, transactions in these funds qualify as party-in-interest transactions. Transactions in the Harsco Stock Fund also qualify as party-in-interest transactions. 5. Plan Amendments: ---------------- The Company amended the Plan effective October 1, 2002, to increase maximum contribution average percentages to 75% of employees' total pay, for both pretax and total contributions. The previous maximum percentages were 16%. The Company amended the Plan effective January 1, 2003, to remove restrictions on contributions made to the company matching account. Participants will direct 100% of future company matching contributions. Amounts credited to the company matching account prior to January 1, 2003 will become available for participant direction as follows: o Effective January 1, 2003 the participant shall have the right to direct the investment of 25% of the restricted company matching account. o Effective April 1, 2003, the participant shall have the right to direct the investment of 33% of the amount then remaining in the restricted company matching account. o Effective July 1, 2003, the participant shall have the right to direct the investment of 50% of the amount then remaining in the restricted company matching account. o Effective October 1, 2003 and thereafter, the participant shall have the right to direct the investment of 100% of the amount then remaining in the restricted company matching account. In accordance with this amendment, effective January 1, 2003, and April 1, 2003, 250,176 shares and 237,851 shares, respectively with a market value of approximately $8.0 and $7.3 million, respectively, was transferred from nonparticipant directed to participant directed accounts. The Company amended the Plan effective on and after January 1, 2003, to limit the participant to a maximum of one loan outstanding at any given time. Participants who currently have multiple loans outstanding will be allowed to retain those loans and repay them according to the loans' original terms. -13-

NOTES TO FINANCIAL STATEMENTS, continued ---------------------------------------- 6. Federal Income Taxes: --------------------- The Company received a determination letter from the Internal Revenue Service on May 15, 2003, that the Plan, as amended March 28, 2003, is a qualified plan under Sections 401(a) and 401(k) of the Internal Revenue Code and is therefore exempt from Federal income taxes under the provisions of Section 501(a). The determination letter renewed the IRS's previous favorable determination made on December 26, 2000. The Plan has been amended since the IRS made its latest determination. However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable provisions of the Internal Revenue Code. 7. Transfers from Other Plans -------------------------- In 1999, the Company acquired Pandrol Jackson, which had its own savings plans. Effective January 1, 2001, participants in the Harsco Track Technologies Security Savings Plan and Harsco Track Technologies UAW 401 (k) Plan were eligible to participate in the Plan. Effective July 1, 2002, $11.6 million in assets from the Track Technologies Savings Plan and Track Technologies UAW 401 (k) Plan were merged into the Plan. -14-
