[1] There were no stock options issued for the three months ended March 31, 2014.

[2] Expected term is calculated using SAB 107, Simplified Formula. Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including, options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

[3] Forfeiture range represents 0% for directors and 21% for employees.
