The Participant shall deliver written notice of any such permitted election to the Company on a form specified by the Company for this purpose at least thirty (30) days (or such other period established by the Company) prior to such Settlement Date. If the Participant elects payment by check, the Participant agrees to deliver a check for the full amount of the required tax withholding to the Company on or before the third business day following the Settlement Date.
