There were
an aggregate of 475,000 and 442,000 potentially dilutive weighted-average shares from convertible securities outstanding for the
three and six months ended June 30, 2013, respectively. These convertible securities were not considered in calculating diluted
net income (loss) per share for the three and six months ended June 30, 2013, as their effect would have been anti-dilutive.
