Proceedings</b></font></p>
<p style="margin-top:6px;margin-bottom:0px; text-indent:4%">
<font style="font-family:Times New Roman" size="2">The Company is
either a defendant or plaintiff in various actions that have arisen
from time to time in the normal course of business, including
intellectual property claims. The Company accrues for a liability
when it is both probable that a liability has been incurred and the
amount of the loss can be reasonably estimated. Significant
judgment is required in both the determination of probability and
the determination as to whether a loss is reasonably estimable. To
the extent there is a reasonable possibility that the losses could
exceed the amounts already accrued, the Company believes that the
amount of any such additional loss would be immaterial to the
Company’s business, financial condition, and results of
operations.</font></p>
