6. Stock-Based Awards

The Company grants equity awards to employees and directors. Options are issued for terms of ten years and vest between two to four years. Options are issued with an exercise price equal to the fair value of the Company on the date of grant. The Company estimated the fair value for options using the Black-Scholes option pricing model. All restricted stock and option awards require future service as a condition of vesting with certain awards subject to acceleration under certain conditions. Restricted stock awards generally vest over three years.
