The Company also issued a preferred stock warrant to Omicron granting them the right to purchase 388.3495 additional shares of the Convertible Preferred, or XXX shares of the Company’s common stock, on a converted basis, which expires on the one year anniversary of the Convertible Preferred issuance.
