   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;The Company&amp;#8217;s tax on loss before income taxes was (1.6%) and (19.2%) for the three months ended
   June&amp;#160;30, 2010 and 2009, respectively. These rates differ from the U.S. Federal rate of tax of 35%
   due to the impact of non-tax deductible acquisition-related share based compensation of
   $77,392 (2009: $117,690); the recognition of a loss on available-for-sale equity investments of
   $955, which is not deductible (2009: $0); and because the Company&amp;#8217;s profits are predominantly
   earned outside the United States, where lower rates of tax apply.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;The Company&amp;#8217;s tax on loss before income taxes was 4.9% and (1.7%) for the six months ended June&amp;#160;30,
   2010 and 2009, respectively. These rates differ from the U.S. Federal rate of tax of 35% due to the
   impact of non-tax deductible acquisition-related share based compensation of $141,309 (2009:
   $236,566); the recognition of a loss on available-for-sale equity investments of $917, which is not
   deductible (2009 loss of $21,217); the release of a provision in respect of unrecognized tax
   benefits of $7,308 (2009: $0) and because the Company&amp;#8217;s profits are predominantly earned outside
   the United States, where lower rates of tax apply.
