Dear Rick:

The following information summarizes the arrangements for your separation from Xerox Corporation (the Company) subject to approval by the Board of Directors or the Executive Compensation and Benefits Committee commencing May 11, 2000.

If you obtain employment as an employee of, or consultant to, another firm or corporation (other than the Company or an affiliate) that is a direct competitor of the Company in any business presently engaged in by the Company or in which the Company as of the date hereof may reasonably be expected to engage in the future, or is or may become such a competitor indirectly through a partnership, joint venture or other business arrangement with, or as a supplier or consultant to, such a direct competitor (“Competitor”), the stock options both vested and non-vested specified in the table below under Options and Rights (the “Stock Options”) will be cancelled immediately. However, if the Company advises you in advance in writing that in its reasonable judgment such other firm or corporation is not a Competitor, the remaining salary continuance will continue to be paid. We will provide notice to you upon your request as to the competitive nature of a prospective employer.

The Company may cancel the Stock Options in the event you disclose confidential business information or if you publicly make any derogatory or disparaging statements about the Company, its management or its business. The Company agrees not to publicly make any derogatory or disparaging statements about you.

BONUS

You will receive $375,000 as a prorated 2000 bonus in February 2001.

You will receive a cash payment of $200,000 in lieu of continuation of life insurance benefits. Payment will be made as soon as administratively possible.
