The "Annual Performance Targets" shall mean the annual performance targets for each applicable calendar year as determined by the Executive Compensation and Option Committee of the Company's Board of Directors and communicated to the Recipient no later than the last day of the first calendar quarter of the applicable calendar year; and (ii) In the event that the Annual Performance Targets for any calendar year are not satisfied so that the Restricted Shares do not vest on the Vesting Date on which they were scheduled to vest had the Annual Performance Targets been met, such Restricted Shares that failed to vest on such Vesting Date shall vest on any subsequent Vesting Date provided that the Annual Performance Targets for a subsequent calendar year are met. If any Restricted Shares remain unvested as of January 1, 2008, Annual Performance Targets shall be set for the 2008 calendar year and if any Restricted Shares have not vested by January 1, 2009, Annual Performance Targets shall be set for the 2009 calendar year. The Vesting Date applicable to the 2008 calendar year is January 1, 2009 and for the 2009 calendar year is January 1, 2010.
