At the Closings (as defined below), the Company hereby agrees to repurchase from the Selling Stockholder, and the Selling Stockholder hereby agrees to sell and deliver, or cause to be delivered, to the Company the Shares. The purchase will occur in three (3) tranches, with the first tranche of $125,000 being on February 8, 2016 (the “First Closing”). The second tranche will be for $250,000 and will occur on February 15, 2016 (the “Second Closing”). The third tranche will be for $375,000 and will occur on February 29, 2016 (the “Third Closing”; the First Closing, the Second Closing, and the Third Closing, collectively, the “Closings” and each a “Closing”). The Selling Stockholder shall not be required to sell any of the Shares at each Closing unless payment is made by the Company.

The Company acknowledges that the Shares are being repurchased at a price equal to the product of a) 135% multiplied by b) the sum of (i) the Stated Value and (ii) all accrued but unpaid dividends (the product of which shall herein be referred to as the “Repurchase Premium”).  Notwithstanding the foregoing, the Company may at any time accelerate the repayment schedule with no additional penalty beyond the Repurchase Premium.

(b) Closings. Subject to the terms and conditions of this Agreement and the delivery of the deliverables contemplated by Section 1(c) of this Agreement, each Closing of the sale of the Shares will take place on the dates set forth in Section 1(a), via the exchange of deliverables, or such other time, date or place as shall be agreed upon by the parties.

(c) Closing Deliveries and Actions. At each Closing, the Company shall deliver to the Selling Stockholder by wire transfer, in accordance with written instructions to be provided by the Selling Stockholder in immediately available funds in an amount equal to the applicable purchase price as set forth in Section 1(a). Additionally, upon execution of this Agreement the Selling Stockholder shall execute a Leak-Out Agreement (the “Leak-Out Agreement) that shall restrict sales of the Company’s common stock as set forth therein.
