&ldquo;<B>Battery</B>&rdquo;), New Enterprise Associates 14, Limited Partnership (&ldquo;<B>NEA</B>&rdquo;), Joel Ackerman, Chief
Executive Officer and a director of the Company (&ldquo;<B>Ackerman</B>&rdquo;), Dr. Ronnie Morris, President and a director of
the Company (&ldquo;<B>Morris</B>&rdquo;), Daniel Mendelson, a director of the Company (&ldquo;<B>Mendelson</B>&rdquo;) and certain
other investors (collectively with Battery, NEA, Ackerman, Morris and Mendelson, the &ldquo;<B>Investors</B>&rdquo;), for the sale
to the Investors of units, each unit consisting of one share of the Company&rsquo;s Common Stock, par value $0.001 per share (the
&ldquo;<B>Common Stock</B>&rdquo;) and a warrant to buy 0.55 shares of Common Stock at $0.48 per share (the &ldquo;<B>Warrants</B>&rdquo;),
at a purchase price of $0.40 per unit, for an aggregate of $14,000,000. The Warrants expire five years after the closing date.
Ackerman and Morris converted convertible promissory notes dated December 1, 2014 in the principal amounts of $1 million each,

2,710,526 units each.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Investors will
have the right to require the Company to repurchase the purchased shares (the &ldquo;<B>Put Option</B>&rdquo;) for cash for $0.40

to file such registration statement by a certain deadline, have it declared effective by a certain deadline or keep it effective
for a certain period of time.</P>

Agreement</B>&rdquo;) due to contractual antidilution provisions in that 2011 Securities Purchase Agreement. The Company also agreed
