   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;In accordance with generally accepted accounting principles, we estimate the full-year
   effective tax rate from continuing operations and apply this rate to our year-to-date income from
   continuing operations. In addition, we separately calculate the tax impact of unusual items, if
   any. For the three months ended June&amp;#160;30, 2010 and 2009, our consolidated effective tax rate for
   continuing operations was 5.1% and 16.5%, respectively. For the six months ended June&amp;#160;30, 2010 and
   2009, our consolidated effective tax rate for continuing operations was 11.4% and 16.1%,
   respectively. The lower tax rate for the 2010 period was principally the result of an increased
   proportion of income in lower tax jurisdictions and the catch-up effect of our current lower annual
   projected tax rate.
