&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;The provision for income taxes for the three months ended June&amp;#160;30, 2013 and June&amp;#160;30, 2012 was approximately $17,000 and $0, respectively. The provision for income taxes consists primarily of foreign income taxes.&lt;/font&gt;&lt;/p&gt;

The provision for income taxes consists primarily of state minimum taxes and foreign income taxes.&lt;/font&gt;&lt;/p&gt;

&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;For the three and six months ended June&amp;#160;30, 2013 and 2012, the provision for income taxes differed from the statutory amount primarily due to state and foreign taxes currently payable, and the Company realized no benefit for current year losses due to maintaining a full valuation allowance against the U.S. and foreign net deferred tax assets.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;The realization of tax benefits of deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that the net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against the domestic and foreign net deferred tax assets as of June&amp;#160;30, 2013 and December&amp;#160;31, 2012. The Company intends to maintain the remaining valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three and six months ended June&amp;#160;30, 2013, there have been no material changes to the total amount of unrecognized tax benefits.&lt;/font&gt;&lt;/p&gt;
