Director Attendance at Annual Meeting
We typically schedule a Board meeting in conjunction with the Annual Meeting. We expect, but do not require, that all directors will attend, absent a valid reason, such as an unavoidable scheduling conflict. Last year, all of the then members of the Board of Directors (except for Stuart G. Moldaw, who was ill and subsequently passed away) attended the 2008 Annual Meeting.
