During our fiscal year ended December 31, 2014, our board of directors held eight meetings (including
regularly scheduled and special meetings), and each director attended at least 75% of the aggregate of (i) the total
number of meetings of our board of directors held during the period for which he or she has been a director and
(ii) the total number of meetings held by all committees of our board of directors on which he or she served during
the periods that he or she served.
Although we do not have a formal policy regarding attendance by members of our board of directors at annual
meetings of stockholders, we encourage, but do not require, our directors to attend. Four directors attended our 2014
Annual Meeting of Stockholders.
Our board of directors has established an audit committee, a compensation committee and a nominating and
corporate governance committee. The composition and responsibilities of each of the committees of our board of
directors is described below. Members will serve on these committees until their resignation or until as otherwise
determined by our board of directors.
