certain product development goals, and had engaged in substantial efforts towards achieving the goal to advance the Company&#146;s Gencaro atrial fibrillation regulatory approval process. However, due to the Company&#146;s limited financial
resources, the Board concluded that the Company would pay cash bonuses for partial achievement of the 2011 performance goals during the 2012 fiscal year upon the achievement of the Gencaro Milestone. Upon achievement of the Gencaro Milestone, the
