Retirement Savings Plan as of December 31, 2003 and 2002 and the related statement of changes in net assets available for benefits for the year ended December 31, 2003. 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 the standards of the Public Company Accounting Oversight Board (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 net assets available for benefits of the Plan at December 31, 2003 and 2002, and the changes in its net assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2003, 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 financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

Retirement Savings Plan Notes to Financial Statements December 31, 2003 and 2002 and Year ended December 31, 2003 1. SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING The financial statements of the Cutler-Hammer de Puerto Rico, Inc. Retirement Savings Plan (the Plan) are prepared under the accrual method of accounting. INVESTMENT VALUATION AND INCOME RECOGNITION Investments are stated at fair value as measured by quoted prices in active markets except for the money market funds, which are stated at fair value as determined by the trustee. Purchases and sales of securities are recorded on a trade-date basis. The cost of shares sold for mutual funds and common shares is based upon the average cost of each participant's shares sold for purposes of determining realized gains and losses. Dividends are recorded on the ex-dividend date. ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results are not expected to differ from these estimates. 2. DESCRIPTION OF PLAN Effective February 1, 1994, Eaton Electrical de Puerto Rico, Inc (the Company or the Plan Sponsor), which was formerly known as Cutler-Hammer de Puerto Rico, Inc., a wholly owned subsidiary of Eaton Corporation, established the Plan. The Plan provides that all employees of the Company are eligible immediately upon employment. Eligible employees may elect to make before-tax contributions to the Plan up to a maximum of 10% of their compensation. The Company has agreed to voluntarily contribute 50% of the employee contributions not exceeding 3% of the total compensation of the employee. 4 Cutler-Hammer de Puerto Rico, Inc. Retirement Savings Plan Notes to Financial Statements (continued) 2. DESCRIPTION OF PLAN (CONTINUED) Contributions are allocated by the employee to any of the five investment funds offered by the Plan. Substantially all administrative, management fees and other expenses of the Plan shall be paid by the Company. Certain transaction costs are borne by the participants. Each participant's account is credited with the participant's contributions and allocations of Company contributions, Plan earnings and transaction costs. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. On termination of service, a participant may receive a lump-sum amount equal to the vested value of his or her account. Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company contribution portion of their accounts plus actual earnings thereon is based on years of continuous service. Participants are 100% vested after three years of credited service or upon the death of the participant. Forfeitures of non-vested amounts shall be used to reduce future Company contributions. As of December 31, 2003, forfeitures held in a suspense account totaled $218,727 and will be used to reduce future company contributions. The Company may amend, modify, suspend or terminate the Plan, provided that no assets held by the Plan or income thereon received by the Key Bank National Association (the Trustee) for the purposes of the Plan shall be used for, or diverted to, purposes other than for the exclusive benefit of participating employees or their beneficiaries. Information about the Plan is contained in the Plan Document, which is available from the Human Resources Department upon request. 3. INVESTMENTS The Trustee of the Plan holds the Plan's investment assets and executes investment transactions. 5 Cutler-Hammer de Puerto Rico, Inc.

INCOME TAX STATUS The Plan has received a determination letter from the Puerto Rico Treasury Department dated August 24, 1999, stating that the Plan meets the requirements for qualification under Puerto Rico income tax laws and that the related trust is exempt from income taxes. Subsequent to this determination the Plan was amended. Once qualified, the Plan is required to operate in conformity with the income tax laws of Puerto Rico to maintain its qualification. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the income tax laws of Puerto Rico and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt. 7 Cutler-Hammer de Puerto Rico, Inc. Retirement Savings Plan Notes to Financial Statements (continued) 6. TRANSACTIONS WITH PARTIES-IN-INTEREST Party-in-interest transactions include the investment in the common stock of Eaton, the investment in the special funds of the trustee and the payment of administrative expenses by the Company. Such transactions are exempt from being prohibited transactions. During 2003, the Plan received $30,577 in common stock dividends from the Eaton Corporation. 7. RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits. 8 Cutler-Hammer de Puerto Rico, Inc.
