Pursuant to the terms of the Emerald Note, Emerald agreed to provide the Company with $200,000 upon execution. In connection with this financing, Emerald received a warrant to purchase 714,286 shares of the Company&amp;#8217;s common stock at an exercise price of $0.65 per share, exercisable over a five year term. The Emerald Note has a maturity date of five years and will bear interest at 8% annually. The unpaid outstanding balance on the Emerald Note may be converted at the option of either party at&amp;#160;a rate of two shares of the Company&amp;#8217;s restricted common stock for each $0.70. In connection with this financing, Emerald received warrants to purchase 714,286 shares of the Company&amp;#8217;s restricted common stock at an exercise price of $0.65 per share, exercisable over a five year term.&amp;#160;&amp;#160;As of June 30, no funds have been received related to this agreement and therefore no shares are considered issuable per the agreement.&amp;#160;&amp;#160;In July, 2013, the Company received a cash payment relating to this agreement. There was no obligation for the Company&amp;#160;to repay at June 30, 2013, so it is not included as a liability at that date.&lt;/font&gt;&lt;/font&gt;&lt;/div&gt;
