Company's 2012 Incentive Compensation Plan (the \"2012 ICP\").  However, the Company subsequently determined that stock options to purchase 7,742 shares of common stock were not validly granted pursuant to the 2012 ICP because such stock options exceeded the limit on the number of stock options that may be granted to any individual participant within any 12-month period. Accordingly, the attempted grant of these excess stock options was ineffective, and such excess stock options were never granted to the reporting person.
