                         Report of Independent Auditors


Corporate Compensation and Organization Committee of Eaton Corporation
Eaton Corporation Share Purchase and Investment Plan


We have audited the accompanying statements of net assets available for benefits
of the Eaton Corporation Share Purchase and Investment Plan as of December 31
and 30, 2001, and the related statement of changes in net assets available for
benefits for the one day period ended December 31, 2001. 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 net assets available for benefits of the Plan at
December 31 and 30, 2001, and the changes in its net assets available for
benefits for the one day period ended December 31, 2001, in conformity with
accounting principles generally accepted in the United States.

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, 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 financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                     One Day Period ended December 31, 2001



1. SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The financial statements of the Eaton Corporation Share Purchase and Investment
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 corporate and government debt securities, which are
valued at market values as determined by the Trustee, based on the mean of the
most recent bid and ask price and other market information available.
Participant notes receivable are valued at their outstanding balances, which
approximate fair value.

Purchases of sales and securities are recorded on a trade-date basis. Dividends
are recorded on the ex-dividend date. The cost of shares sold for the mutual
funds and the common shares is based upon the average cost of each participant's
shares sold for purposes of determining realized gains and losses.

ESTIMATES

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

2. DESCRIPTION OF PLAN

Effective December 30, 2001, the Plan year-end was changed to December 31.
Effective January 1, 2002, the Plan was amended and restated. In conjunction
with the amendment and restatement, the Plan was renamed The Eaton Savings Plan.


                                                                               4

              Eaton Corporation Share Purchase and Investment Plan

                    Notes to Financial Statements (continued)


2. DESCRIPTION OF PLAN (CONTINUED)

The Plan generally provides that an Eaton employee who is in the regular service
of a class in a division or group to which Eaton Corporation (Eaton, the
Company, or the Plan Sponsor) has extended eligibility for membership in the
Plan (other than a temporary employee who is hired for a specific, limited
period of time or for the performance of a specific, limited assignment or
employees covered by a collective bargaining agreement that does not specify
coverage under the Plan) will be eligible to participate on any date established
in accordance with administrative procedures which follows the date an employee
first incurs an hour of service.

Employees may make a combination of before-tax and after-tax contributions
ranging from 1% to 17% of base pay. Employee contributions up to 6% of eligible
compensation are eligible for employer match. Participants may change their
contributions monthly and accounts are valued daily. Eaton matches regular
employee contributions as determined under a formula. This formula compares
Eaton's earnings per share for the most recently reported calendar quarter with
the average of Eaton's per share earnings for the previous two calendar years.
If the most recently reported calendar quarter's earnings per share are
identical to the two calendar year average, the Company's matching contribution
will be 50% for each dollar contributed by employees. Company matching
contributions will increase or decrease depending on whether the most recently
reported calendar quarter's earnings per share are greater than or less than the
two calendar year average, respectively. For each 2% that the most recently
reported calendar quarter's earnings per share is greater than or less than the
two calendar year average, 1% will be added or subtracted respectively from the
standard Company matching contribution of 50%. Company matching contributions
will not be less than $.25, or more than $1.00 for each dollar of regular
employee contributions, except under special circumstances as defined in the
Plan document. There will be an additional $.10 match per dollar of before-tax
and after-tax contributions, up to 17% of eligible compensation, to match
contributions initially invested in the Eaton Common Shares Fund. This match is
reduced to $.05 for certain highly compensated employees.

Each participant's account is credited with an allocation of the Plan's earnings
based on participant account balances, as defined.

Eligible employees may borrow from their accounts a minimum of $1,000, up to a
maximum equal to the lesser of $50,000 or 50% of their vested account balance
reduced by their highest outstanding loan balance during the preceding 12
months. The loans are secured by the balance in the participant's account and
bear interest at a published rate, as defined. Principal and interest is paid
ratably through payroll deductions.

                                                                               5

                    Notes to Financial Statements (continued)



2. DESCRIPTION OF PLAN (CONTINUED)

Company contributions are provisionally allocated during the year and become
non-forfeitable on the last day of each Plan year or upon other events as
indicated in the Plan document.

All Company matching contributions are invested in the Eaton Common Shares Fund.
Employee contributions may be invested in any of the fund options available
under the Plan. Participants may reallocate their accumulated contributions
daily among the various funds consistent with the ratios specified in the Plan.

All costs and expenses incurred in administering the Plan are paid by the Plan
unless otherwise determined by Eaton.

Eaton may amend, modify, suspend or terminate the Plan. No amendment,
modification, suspension or termination of the Plan shall have the effect of
providing that any amounts then held under the Plan may be used or diverted to
any purpose other than for the exclusive benefit of members or their
beneficiaries.

Information about the Plan is contained in the Plan document, which is available
from the Company's Human Resources Department upon request.

3. CONTRIBUTIONS

Company matching contributions during December 2001 were made at $.25 per dollar
of regular employee contribution.

4. INVESTMENTS

Key Trust Company of Ohio, N.A., the Trustee of the Plan, holds the Plan's
investment assets and executes investment transactions.

                                                                               6

              Eaton Corporation Share Purchase and Investment Plan

                    Notes to Financial Statements (continued)



6. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated April 2, 1996, stating that the Plan is qualified under Section 401(a) of
the Internal Revenue Code (the Code) and, therefore, the related trust is exempt
from taxation. Subsequent to the issuance of the determination letter, the Plan
was amended. Once qualified, the Plan is required to operate in conformity with
the Code to maintain its qualification. The Plan Sponsor has indicated that it
will take necessary steps, if any, to maintain the Plan's qualified status.

7. TRANSACTIONS WITH PARTIES-IN-INTEREST

Party-in-interest transactions included the investments in the common stock of
Eaton and the special funds of the trustee and the payment of administrative
expenses by the Company. Such transactions are exempt from being prohibited
transactions.

On June 30, 2000, Eaton reorganized its semiconductor equipment operations into
a wholly owned subsidiary, Axcelis Technologies, Inc. (Axcelis). In July 2000,
Axcelis completed an initial public offering for the sale of 20% of its common
shares. On December 29, 2000, Eaton distributed its remaining interest in
Axcelis to Eaton shareholders as a dividend (spin-off), which was tax free to
Eaton and its shareholders for United States income tax purposes. Eaton
shareholders (including the Plan) received 1.179023 shares of Axcelis common
stock per each whole Eaton common share held as of December 6, 2000 and cash
payments for fractional shares. The Axcelis common shares were received by the
Plan on January 5, 2001.

The Plan established an Axcelis Common Stock Fund to hold the shares of Axcelis
common stock received as a dividend, and which shall be maintained as a fund
under the Plan for a period expiring on or before December 31, 2002. Upon
termination of the Axcelis Common Stock Fund, all Axcelis common stock held by
the Plan shall be sold and invested in a money market fund or stable value fund.
Distributions from the Axcelis Common Stock Fund shall be made in cash. Cash and
stock dividends on the Axcelis common stock shall be invested in a stable value
fund and Axcelis Common Stock Fund, respectively. Axcelis common stock received
by the Plan shall be credited under the Plan to the participant's account
related to the Eaton common shares with respect to which the Axcelis common
stock was received as a dividend. Participants are not allowed to direct
contributions or transfers to the Axcelis Common Stock Fund, but are permitted
to direct the transfer of amounts in the Axcelis Common Stock Fund to other
funds available under the Plan.
