These options vest in three equal annual installments and have an exercise price equal to the closing price of our common stock on the NYSE on the date of
grant.

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.
