and per share data have been adjusted to give effect to the one-for-seven reverse stock split implemented on August 16, 2012 as
described in note 5 above.&lt;/p&gt;

&lt;p style="font: 8pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 8pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The Company computes
basic loss per share using the weighted average number of common shares outstanding during the period. The Company computes diluted
loss per share using the weighted average number of common and dilutive common equivalent shares outstanding during the period.
Common equivalent shares consist of the incremental common shares issuable upon the exercise of stock options. Common equivalent
shares are excluded from the calculation if their effect is anti-dilutive.&lt;/p&gt;
