     The compensation of our non-employee directors is determined on an
approximate 52-week period (the "Annual Directors Term") that runs from annual
meeting date to annual meeting date rather than on a calendar year. A director
may elect to receive his or her annual fee or meeting attendance fees for an
Annual Directors Term in the form of shares of common stock in lieu of cash
payments. If a director elects to receive shares of common stock in lieu of cash
as payment for the annual fee or meeting attendance fees, the number of shares
to be received by the director will be determined by dividing the dollar value
of the annual fee or the meeting attendance fees owed by the closing price of
our common stock as reported on the NYSE on the last day of the Annual Directors
Term.

     Directors generally make their elections as to the form of compensation for
his or her annual fee or meeting attendance fees in July of each year and such
election is valid for the Annual Directors Term beginning in the calendar year
in which the election is made.

     Non-employee directors are also eligible to receive stock options under our
stock incentive plans. Directors who are officers or employees of Keane do not
receive any additional compensation for their services as directors.
