        <footnote id="F1">On March 31, 2014, the Issuer issued 2,377,500 shares of Series A Convertible Preferred Stock (the &quot;Preferred Stock&quot;) to Global Capital Partners, LLC (&quot;Global&quot;). Global has served as a financier of the Issuer, and the Issuer currently has outstanding notes with Global. The Preferred Stock was issued to Global in consideration of its willingness to continue extending the due dates under the promissory notes which the Issuer has with Global. Each share of Preferred Stock is convertible, at Global's option, for no additional consideration into 10 shares of common stock of the Issuer.</footnote>
        <footnote id="F2">Strato Malamas owns 100% of Global and is in a position to determine the investment and voting decisions of Global and may be deemed to indirectly beneficially own the shares of Preferred Stock of the Issuer owned by Global.</footnote>
