The Company generally grants stock options to employees and directors at exercise prices equal to the fair market value of the Company’s stock on the dates of grant. Stock options are typically granted throughout the year and generally vest over four years of service and expire ten years from the date of the award, unless otherwise specified. The Company recognizes compensation expense for the fair value of the stock options over the requisite service period for each stock option award. Total share-based compensation expense included in the consolidated statements of operations for the years ended December 31, 2018 and 2017 is $1,145,530, of which $868,015 is related to stock options, and $719,796, of which $510,496 is related to stock options, respectively. There was no capitalized share-based compensation cost as of December 31, 2018 and 2017, and there were no recognized tax benefits during the years ended December 31, 2018 and 2017. To estimate the value of an award, the Company uses the Black-Scholes option-pricing model. This model requires inputs such as expected life, expected volatility and risk-free interest rate. The forfeiture rate also impacts the amount of aggregate compensation. These inputs are subjective and generally require significant analysis and judgment to develop. While estimates of expected life, volatility and forfeiture rate are derived primarily from the Company’s historical data, the risk-free rate is based on the yield available on U.S. Treasury constant maturity rates with similar terms to the expected term of the stock option awards. The fair value of share-based awards was estimated using the Black-Scholes model with the following weighted-average assumptions for the years ended December 31, 2018 and 2017: Assumptions: 2018 2017 Dividend yield 0.00 0.00 Risk-free interest rate 2.68-3.10 % 1.91-2.45 % Expected volatility 104.9-137.3 % 115.9-139 % Expected life (in years) 5-10 5-10 Option activity for the year ended December 31, 2018 and 2017 was as follows: Weighted Average Weighted Average Exercise Remaining Aggregate Price Contractual Intrinsic Options ($) Life (Yrs.)

Sixteen of the 2018 option grants have an exercise price currently below $1.50. At December 31, 2018, there was $312,655 of unrecognized share-based compensation expense related to unvested share options with a weighted average remaining recognition period of 6.47 years.
