The initial closing further to the Agreement consisted of the issuance of 1,388,888 Shares and Warrants to purchase 1,388,888 shares of Common Stock to a single institutional investor at a purchase price of $10 million. The Agreement contains customary representations, warranties and agreements of the Company, customary conditions to closing and obligations of the parties.
