[1] In connection with the IPO, placement agent warrants for the purchase of Series A Preferred Stock were amended such that the warrants became exercisable for the number of common stock that would have been issued upon the exercise of the Series A warrant and subsequent conversion to common stock upon the consummation of the IPO. The exercise price was amended to the price equal to the total proceeds that would have been required upon the exercise of the original warrant, divided by the amended number of warrant shares. The amendment was accounted for as a modification of a stock award. The Company determined that there was no incremental increase in the fair value for the amendment of the award and accordingly there was no charge to the statement of operations for the years ended December 31, 2018.
