NOTES PAYABLE | From January 9, 2015 through February 5, 2015, the Company issued promissory notes to certain investors in the aggregate principal amount of approximately $1.1 million. On March 17, 2015, the Company issued Senior Secured Convertible Notes (the “Secured Notes”) to certain investors under which the Company borrowed approximately $7.4 million. National Securities Corporation (“NSC”) acted as placement agent and the Company paid brokerage commissions to NSC of approximately $785,700 and issued to NSC a warrant (the “2015 NSC Warrant”) to purchase ten percent of the common shares issuable upon conversion of Secured Notes in the principal amount of $7,372,557 at an exercise price of $7.362 per share, subject to adjustment to an exercise price equal to the conversion price of the Secured Notes when such conversion price became determinable. The number of shares issuable upon exercise of the 2015 NSC Warrant was initially set at 100,144 shares of the Company’s common stock, subject to later adjustment to a number of shares equal to 10% of the shares issuable upon conversion of the Secured Notes. The brokerage commissions are being amortized as interest expense over the life of the loan. In addition, on March 17, 2015, the Company exchanged all of its existing unsecured convertible promissory notes for Secured Notes with an aggregate principal balance of approximately $7.3 million. The total closing represented $14.75 million. The Secured Notes were due on May 31, 2016 and accrued interest at a rate of 10% per annum, except in any event of default in which case the interest rate shall be 12% per annum. During March 2016, the maturity date of the Secured Notes was extended to May 31, 2017. All other terms of the Secured Notes remained the same. The Secured Notes automatically convert to common stock in the event of an IPO of the Company and are optionally convertible upon a subsequent placement of equity other than an IPO or at the discretion of the note holder. Based on the method of conversion, the Secured Notes are converted into common stock at the Conversion Price, as defined in the agreement. During April 2016, the Company issued additional Secured Notes in the aggregate principal amount of approximately $5,958,000. These notes have the same terms as the previous Secured Notes and mature on May 31, 2017. NSC acted as placement agent and the Company paid NSC a brokerage commission in the amount of ten percent of the proceeds from the Secured Notes placed by NSC, or approximately $438,000, and issued to NSC a warrant to purchase ten percent of the common shares issuable upon conversion of Secured Notes in the principal amount of approximately $4.4 million at an exercise price equal to the conversion price of the Secured Notes. In June 2016, and prior to any exercise of the warrant, NSC elected to cancel the warrant in full and for no consideration. During the three months and nine months ended September 30, 2016, the interest expense on the Secured Notes was approximately $1.3 million and $2.6 million, respectively. During the three and nine months ended September 30, 2015, the interest expense on the Secured Notes was approximately $568,000 and $1.4 million, respectively. On August 10, 2016, upon consummation of the IPO, all principal and accrued interest due under the Secured Notes, totaling approximately $23.5 million converted into 6,264,659 shares of common stock of the Company, which was based on a conversion price of $3.75 (50% of the price of shares sold in to the public in the IPO, as provided in the terms of the Secured Notes). The determination of the conversion price and number of shares issuable upon conversion of the Secured Notes triggered an adjustment to the 2015 NSC Warrant, increasing the number of shares issuable by 96,458 (to a total of 196,502 shares) and setting the exercise price at $3.75 per share. The modification of the number of shares issuable and exercise price of the 2015 NSC Warrant increased its fair value resulting in addition interest expense recognized in August, 2016 (See Note 7). |
