Conversion of bridge notes, description The 2018 Convertible Notes, each holder also received contingent five-year warrants to purchase common stock in an amount equal to 50% of the shares of common stock that the holder was entitled to in connection with the conversion of the holder's 2018 Convertible Note when such note first became convertible, which was at the time the IPO was priced. Prior to the 2018 Convertible Note being convertible, the holder did not have a right to exercise these warrants. At the IPO pricing date, 615,585 warrants to purchase common stock became exercisable upon the conversion of the outstanding balance of the 2018 Convertible Notes, including accrued interest. The warrants have an exercise price of 125% of the conversion price, or $3.185. The Company calculated the fair value of the warrants at $1,741,334 using a Black-Scholes pricing model. The Company valued the warrants at $2.8288 per warrant using a common stock fair value of $5.00, a term of five years, a volatility of 45% and a risk-free interest rate of 2.75%. The Company allocated the debt proceeds on a relative fair value basis between the note and warrant, in which the Company recognized a note discount for $1,107,982. This was immediately recognized in interest expense as of the note conversion date. The 2018 Convertible Notes provided that the principal and all accrued and unpaid interest on the 2018 Convertible Notes were convertible into shares of common stock at a conversion rate equal to the lesser of $2.5480 per share or seventy percent (70%) of the IPO price per share.
