During the year ended December 31, 2017 and in connection with the Private Placement, investors received warrants to purchase 5,929,256 shares of common stock. The warrants have an exercise price of $2.41 per share and expire three years from the date of issuance.

The placement agent warrant has an exercise price of $2.89 per share, is non-exercisable for 12 months and has a three-year term from the date of issuance. The warrants contain a provision to protect investors from potential future dilutive events, or a down-round provision. The Company elected to early adopt ASU 2017-11 and will recognize the value of the effect of the down-round provision, if and/or when triggered.
