   &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 September&amp;#160;30, 2010 and 2009, our consolidated effective tax rate
   for continuing operations was (54.0%) and 18.5%, respectively. For the nine months ended September
   30, 2010 and 2009, our consolidated effective tax rate for continuing operations was 1.6% and
   16.6%, respectively. The lower tax rate for the 2010 period was principally the result of lower
   income from continuing operations in 2010, tax benefits related to the adjustment of intercompany
   pricing in the completion of our 2009 tax return during the third quarter of 2010, an increased
   proportion of income in lower tax jurisdictions, and the catch-up effect of our current lower
   annual projected tax rate.
   &lt;/div&gt;
