Item 5.  Other Events and Regulation FD Disclosure.

         (a) Subsequent to the mailing to shareholders of Eaton Corporation's
Definitive Proxy Statement dated March 19, 2004 in connection with its annual
meeting to be held on April 28, 2004, it was discovered that erroneous
compensation data were used to calculate the long-term incentive payment for
R.W. Carson for the four-year period ending December 31, 2003. Instead of
$602,763, as shown in the Summary Compensation Table contained on page 15 of the
Proxy Statement, the correct amount is $822,483. On April 5, 2004, the Company's
Compensation and Organization Committee approved a payment to Mr. Carson in
order to correct the underpayment.

         (b) The following table summarizes information about stock options
outstanding and exercisable at March 1, 2004:
