We have recorded compensation expense of $21,737 related to the options during the three and six months ended June 30, 2020.

On May 14, 2020 the Company granted to its current Chief Financial Officer 431,251 options to purchase common stock, exercisable at $2.50 per share, under the terms of the 2017 Equity Incentive Plan. The options have a term of five years. The options will vest over a two-year period in equal quarterly installments on the last day of each calendar quarter, with the first portion vesting on the last day of the calendar quarter during which the Company's securities begin trading on NYSE American or the Nasdaq Capital Market, subject to serving as the Chief Financial Officer of the Company on each applicable vesting date. The award has been valued at $1,077,999 using the Black Sholes model and compensation expense will be recorded over the estimated vesting period. We have recorded compensation expense of $56,737 related to the options during the three and six months ended June 30, 2020.

Warrants Recorded as Derivative Liabilities Series D Preferred Stock Warrants The Company identified embedded features in the warrants issued with Series D Preferred Stock in 2019 and 2020 which caused the warrants to be classified as a derivative liability. These embedded features included the right for the holders to request for the Company to cash settle the warrants to the holder by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of the warrants on the date of the consummation of a fundamental transaction, as defined in the warrant instrument. The accounting treatment of derivative financial instruments requires that the Company treat the whole instrument as liability and record the fair value of the instrument as a derivative as of the inception date of the instrument and to adjust the fair value of the instrument as of each subsequent balance sheet date. As of the issuance date of the unit warrants issued in 2020 in connection with the sale of Series D Preferred Stock (See Note 9), the Company determined a fair value for the derivative liability of $26,465 for the 8,594 warrants, which has been charged to paid in capital. The fair value of the warrants was determined using the Black-Scholes Model based on a risk-free interest rate of 0.34%, an expected term of 5 years, an expected volatility of 344% and a 0% dividend yield. As a result of the sale of convertible notes and warrants as described in Note 8, the number and exercise price of the Series D Preferred Stock warrants outstanding was adjusted due to anti-dilution provisions in the warrants. The exercise price was reduced to $1.60 from $4.80 and the number of warrants was increased from 479,533 to 1,438,599. We have recorded an expense for the change in derivative value due to the anti-dilution adjustments of $2,642,175 as a result of the trigger of the anti-dilution provision. During the three and six months ended June 30, 2020, the Company recorded other expense of $72,886 and $637,974, respectively, related to the change in the fair value of the derivative. The fair value of the embedded derivative was $3,918,656 as of June 30, 2020, determined using the Black Scholes model based on a risk-free interest rate of 0.235% - 0.29%, an expected term of 3.75 – 4.95 years, an expected volatility of 334 - 357% and a 0% dividend yield. Convertible Debenture Warrants and Placement Agent Warrants The Company identified embedded features in the warrants issued with the convertible debt and the placement agent warrants in 2020 (see Note 8) which caused the warrants to be classified as a derivative liability. These embedded features included the right for the holders to request for the Company to cash settle the warrants to the holder by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of the warrants on the date of the consummation of a fundamental transaction, as defined in the warrant instrument. The accounting treatment of derivative financial instruments requires that the Company treat the whole instrument as liability and record the fair value of the instrument as a derivative as of the inception date of the instrument and to adjust the fair value of the instrument as of each subsequent balance sheet date. As of the issuance date of the Debenture warrants, the Company determined a fair value of $4,665,877 for the 1,845,703 warrants. The fair value of the warrants was determined using the Black-Scholes Model based on a risk-free interest rate of 0.22%, an expected term of 2.93 – 3 years, an expected volatility of 252% - 341% and a 0% dividend yield. Of this amount, $1,325,323 was recorded as debt discount (see Note 8) and $3,340,554 was charged to expense as initial derivative expense. As of the issuance date of the placement agent warrants, the Company determined a fair value of $933,177 for the 369,141 warrants. The fair value of the warrants was determined using the Black-Scholes Model based on a risk-free interest rate of 0.22%, an expected term of 2.93 – 3 years, an expected volatility of 252% - 341% and a 0% dividend yield. The value of $933,177 has been recorded as debt cost (see Note 8). During the three and six months ended June 30, 2020, the Company recorded other expense of $266,202 related to the change in the fair value of the derivative. The fair value of the embedded derivative was $5,865,256 as of June 30, 2020, determined using the Black Scholes model based on a risk-free interest rate of 0.18%, an expected term of 2.91 years, an expected volatility of 253% and a 0% dividend yield. | NOTE 10 — STOCK OPTIONS AND WARRANTS 2014 Equity Incentive Plan The 2014 Equity Compensation Plan ("2014 Plan") is administered by the Board and provides for the issuance of up to 6,385 shares of common stock. Under our 2014 Plan, we may grant stock options, restricted stock, stock appreciation rights, restricted stock units, performance units, performance shares and other stock based awards. As of December 31, 2019 no awards are outstanding under the 2014 Plan. The Company does not anticipate granting any awards under the 2014 plan in the future. 2017 Equity Incentive Plan In October 2017, our Board and shareholders authorized the 2017 Equity Incentive Plan (the "2017 Plan"), covering 475,000 shares of common stock. In December 2019, the number of shares authorized under the 2017 Plan was increased to 1,098,959 shares. The purpose of the 2017 Plan is to advance the interests of the Company and our related corporations by enhancing the ability of the Company to attract and retain qualified employees, consultants, officers, and directors, by creating incentives and rewards for their contributions to the success of the Company and its related corporations. The 2017 Plan is administered by our Board or by the Compensation Committee. The following awards may be granted under the 2017 Plan:
| ● | incentive stock options ("ISOs")
| ● | non-qualified options ("NSOs")
| ● | awards of our restricted common stock
| ● | stock appreciation rights ("SARs")
| ● | restricted stock units ("RSUs")
Any option granted under the 2017 Plan must provide for an exercise price of not less than 100% of the fair market value of the underlying shares on the date of grant and not less than $1.60 per share, but the exercise price of any ISO granted to an eligible employee owning more than 10% of our outstanding common stock must not be less than 110% of fair market value on the date of the grant. The plans further provide that with respect to ISOs the aggregate fair market value of the common stock underlying the options which are exercisable by any option holder during any calendar year cannot exceed $100,000. The exercise price of any NSO granted under the 2017 Plan is determined by the Board at the time of grant, but must be at least equal to fair market value on the date of grant. The term of each plan option and the manner in which it may be exercised is determined by the Board or the Compensation Committee, provided that no option may be exercisable more than 10 years after the date of its grant and, in the case of an incentive option granted to an eligible employee owning more than 10% of the common stock, no more than five years after the date of the grant. The terms of any other type of award under the 2017 Plan is determined by the Board at the time of grant.
