[1] Per the 2013 Long-Term Incentive Plan, non-employee directors will receive annual awards of restricted stock, as opposed to stock options. The number of shares of restricted stock to be granted will be established from time to time by the Board of Directors. Currently, the number of shares of restricted stock awarded annually to each non-employee director generally will be determined by dividing $100,000 by the equity award value of the common stock on the date of grant, as defined in the 2013 Long-Term Incentive Plan. These awards will generally vest in full on the day that is six months after the date of grant or upon the earlier occurrence of (i) the director’s termination of service as a director by reason of death, disability or retirement, or (ii) a change in control by the Company. The compensation expense associated with these awards will be recognized on a pro-rata basis over this period.
