On September 3, 2015, we entered into a Loan Conversion Agreement (“Conversion Agreement”) with Esenjay Investments LLC, our major stockholder and principal credit line holder (“Esenjay”), pursuant to which we agreed to issue 51,171,025 shares of our common stock (based on $0.04 per share) (the “Shares”) in exchange for the cancellation of a total principal amount of $2,000,000 (“Principal Amount”) outstanding under the Secondary Revolving Promissory Note, the Bridge Loan Promissory Note and the Unrestricted Line of Credit (collectively, the “Loan Agreements”), with Esenjay, plus $46,841 in accrued and unpaid interest on such Principal Amount as of September 3, 2015 (the accrued interest together with the Principal Amount referred to as the “Debt”). In addition, under the Conversion Agreement, we agreed to allow Esenjay the right to convert additional amounts to be borrowed under the Loan Agreements at the conversion price equal to the future offering price of our Shares. The Loan Agreements expire December 31, 2015.
