Stock Incentive Plan

In 2015, the board of directors (the Board) and stockholders approved the Company’s Amended and Restated 2004 Stock Award and Incentive Plan, or the Amended and Restated Plan. The Amended and Restated Plan amends the Company’s pre-existing Amended and Restated 2004 Stock Award and Incentive Plan, which had replaced the 1998 Stock Option Plan, or the 1998 Plan, and the 2000 Omnibus Incentive Compensation Plan, or the 2000 Plan. The Amended and Restated Plan authorized an additional 2,450,000 shares for new awards and combined the remaining shares available under the original Amended and Restated Plan. Eligible participants under the Amended and Restated Plan include officers and other employees of the Company, members of the Board and outside consultants, as specified under the Amended and Restated Plan and designated by the Compensation and Management Development Committee of the Board, or the Compensation Committee. Unless earlier terminated by action of the Board, the Amended and Restated Plan will remain in effect until such time as no stock remains available for delivery under the Amended and Restated Plan and the Company has no further rights or obligations under the Amended and Restated Plan with respect to outstanding awards thereunder.

Historically, stock options have been granted with an exercise price equal to the market value of the common stock on the date of grant, expire 10 years from the date they are granted, and generally vested over a two-year period for members of the Board of Directors and a three-year period for employees. Upon exercise, new shares can be issued by the Company. The Company granted stock options in 2016, which vest monthly over a one-year period. SARs are generally granted with a grant price equal to the market value of the common stock on the date of grant, vest one-third each year on the anniversary of the date of grant and expire five years from the date of grant. The restricted shares and restricted stock units (RSU’s) granted to employees historically have had a three year cliff vesting period and are subject to accelerated vesting and forfeiture under certain circumstances. Restricted shares and restricted stock units granted to board members generally have had a three year graded vesting period and are subject to accelerated vesting and forfeiture under certain circumstances.

In March of 2017, the Company’s Chief Executive Officer, Chief Financial Officer and members of The Board were granted incentive stock options to purchase an aggregate of 172,077 shares of common stock with a weighted average exercise price of $2.13 per share and, subject generally to the executive’s or board member’s, as applicable, continued service with the Company, vest in equal monthly installments over a period of one year.

The following table provides the weighted average assumptions used in determining the fair value of the stock option awards granted during the three month period ended March 31, 2017. There were no options granted during the three month period ended March 31, 2016.

The Company recognized approximately $0.1 million and $0.1 million of stock-based compensation expense during each of the three month periods ended March 31, 2017 and 2016, respectively.
