(1)	The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the exercise price of the option at December 31, 2017. If the exercise price exceeds the market value, there is no intrinsic value.

During the year ended December 31, 2017, the Company did not grant employee stock options or stock options for consulting services.

The fair value of the stock option grants are amortized over the respective vesting period using the straight-line method and assuming no forfeitures and cancellations.

Compensation expense related to stock options included in general and administrative expense in the accompanying statements of operations for the years ended December 31, 2017 and 2016, was $312,351, and $86,733, respectively.

Stock options are granted at the fair market value of the Company’s common stock on the date of grant. Options granted to officers and other employees vest immediately or over 36 months as provided in the option agreements at the date of grant.

The fair value of each option granted in 2017 and 2016 was estimated using the Black-Scholes Option Pricing Model. The following assumptions were used to compute the weighted average fair value of options granted during the periods presented.
