The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market Value up to the maximum individual statutory rate for each applicable jurisdiction, (c) delivering to the Company already-owned Shares having a Fair Market Value up to the maximum individual statutory rate for each applicable jurisdiction, or (d) selling a sufficient number of Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) up to the maximum individual statutory rate for each applicable jurisdiction. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. Notwithstanding anything contained herein to the contrary, any Participant who is subject to Section 16 of the Exchange Act may satisfy his or her tax withholding obligations by directing the Company to withhold a number of Shares from those that he or she would otherwise receive upon the exercise, vesting or settlement of an Award having a Fair Market Value (determined as of the date on which the withholding obligation arises) up to the maximum individual statutory rate for each applicable jurisdiction.”
