(3)	The restricted stock units vest on the one-year anniversary of the grant date only if the reporting person attends at least 75% of the regularly scheduled meetings of the issuer's Board and his or her committee meetings from the date of grant until the date of the issuer's next annual meeting of shareholders. Shares will be issued to the reporting person upon vesting unless the reporting person has elected to defer receipt of shares.
