Stock-Based Compensation and Warrants | 8. Stock-Based Compensation and Warrants The Plan - In 2007, the Company adopted the First Amended 2007 Stock Incentive Plan, as amended (the “Plan”). The Plan provides for the grant of Incentive Stock Options, Nonqualified Stock Options, Restricted Stock Awards, Restricted Stock Unit Awards, Performance Awards and other stock-based awards, or any combination of the foregoing to the Company’s key employees, non-employee directors and consultants. Under the Plan, the exercise price is determined by the Board of Directors or the compensation committee of the Board of Directors, and for options intended to qualify as qualified incentive stock options, may not be less than the fair market value as determined by the closing stock price at the date of the grant. Each option and award shall vest and expire as determined by the Board of Directors or the compensation committee. Options expire no later than ten years from the date of grant. All grants provide for accelerated vesting if there is a change of control, as defined in the Plan. Stock-based compensation expense was $0.1 million for the three months ended March 31, 2016 and March 31, 2015. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for the three months ended March 31, 2016 and March 31, 2015 was approximately $53,000 and $63,000, respectively. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended March 31, 2016 and March 31, 2015 was approximately $42,000 and $29,000, respectively. 2016 2015 Risk-free interest rate 1.49 % 1.74 % Expected volatility 108 % 145 % Expected term in years 6.1 6.1 Dividend yield - % - % Weighted- Average Exercise Options Price (in thousands) Outstanding at December 31, 2015 5,752 $ 1.05 Granted 150 1.40 Outstanding at March 31, 2016 5,902 1.06 Exercisable at March 31, 2016 5,166 $ 0.99 As of March 31, 2016, the aggregate intrinsic value of outstanding stock options was $9.1 million.

The warrants issued in connection with the sale of units of common stock were for cash value received and as such were not grants of compensation-based warrants. |
