Including the Notes and Warrants issued at the Initial Closing and the Second Closing, the Company has issued Notes in the aggregate principal amount of $950,000 and Warrants to purchase an aggregate of 950,000 shares of common stock pursuant to the Purchase Agreement.

The Notes are secured by a first priority security interest in all of the assets of the Company pursuant to the terms of the Security Agreement dated December 7, 2012 (the “Security Agreement”). In addition, up to $1,000,000 in aggregate principal amount of the Notes is guaranteed by Steven Leber, Joseph Bernstein and Dr. Robert Cohen pursuant to the Limited Guaranty of Payment dated December 7, 2012 (the “Guaranty”).
