Convertible Notes

On January 22, 2018, the Company entered into a Securities Purchase Agreement (“SPA”) with fourteen accredited investors (individually, a “Buyer” and collectively, the “Buyers”) pursuant to which the Company agreed to issue to the Buyers senior convertible notes in an aggregate principal amount of $7,760,510 (the “Notes”), which Notes shall be convertible into the Company’s common stock, par value $0.001 per share (the “Common Stock”) at a price of $4.58 per share, and five-year warrants to purchase the Company’s Common Stock representing the right to acquire an aggregate of approximately 1,694,440 shares of Common Stock (the “Warrants”).

Pursuant to the terms of SPA the Notes were subject to an original issue discount of 10% resulting in proceeds to the Company of $7,055,000 from the transaction.

Upon the purchase of the Notes, the Buyers received Warrants to purchase 1,694,440 shares of Common Stock. Such Warrants are exercisable for (5) years from the date the shares underlying the Warrants are freely saleable. The initial Exercise Price is $4.58. According to the terms of the warrant agreement, the Warrants are subject to certain adjustments depending upon the price and structure of a subsequent financing, including a qualified financing with gross proceeds of at least $20 million, as defined in the agreements.

The issuance of the Notes and Warrants were made in reliance on the exemption provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) for the offer and sale of securities not involving a public offering, and Regulation D promulgated under the Securities Act.
