        <footnote id="F1">The exercise price of the transferred warrants was $2.00; however, at the time of the assignment, they were subject to a temporary exercise price reduction that reduced the exercise price to $1.30 through December 31, 2016.</footnote>
        <footnote id="F2">The warrants were assigned by the reporting person to an unaffiliated third party for no consideration.</footnote>
        <footnote id="F3">The warrants contain a blocker that prohibits the holder from exercising the warrants if such exercise will result in the beneficial ownership by the holder of more than 9.99% of the Issuer's outstanding shares. The blocker may only be  amended by written consent of both the Issuer and the holder. Once the holder's beneficial ownership percentage, calculated in accordance with Rule 13d-3(i), reaches 9.99%, warrants will not be exercisable until such time as the holder's beneficial ownership percentage falls to 9.99% or below.</footnote>
