Any shares earned pursuant to the attainment of a performance level shall vest 50% upon the compensation committee certification of the attainment of the performance level (provided, however, that no shares may be earned or vest prior to the first anniversary of the grant date) and the remaining 50% shall vest at the end of the Performance Period, subject to the recipient’s continuous employment or service through each such vesting date. | |||
