<div align="left" style="font-size: 10pt; margin-top: 6pt">     As of December 31, 2010, we have U.S. and foreign net operating loss carryforwards
(“NOLs”) of approximately $182.6 million and $5.9 million, respectively, available to offset future
taxable income. Approximately $94.3 million of these NOLs are subject to annual limitations
including $18.8 million of NOLs resulting from the acquisition of Camiant. If certain substantial
changes in our ownership should occur in the future, there would be a change in the previously
mentioned annual limitation on the utilization of the NOLs in periods subsequent to the ownership
change. In addition, we have federal and state research and development credit carryforwards of
$10.1 million and $4.1 million, respectively, available to offset future tax liabilities. Our NOLs
will begin to expire in 2024, if not utilized. Our federal research and development tax credit
will begin to expire in 2026, if not utilized, and our state research and development tax credit
will begin to expire in 2017, if not utilized.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     We provide for U.S. income taxes on the earnings of foreign subsidiaries unless the
subsidiaries’ earnings are considered indefinitely reinvested outside of the United States. As of
December 31, 2010, we have not provided for deferred income tax of approximately $13.5 million
related to approximately $46.6 million of cumulative undistributed earnings of our foreign
affiliates, as we intend to permanently reinvest these earnings to fund future expansion of these
international operations.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     We conduct business globally, and as a result, most of our subsidiaries file income tax
returns in various domestic and foreign jurisdictions. In the normal course of business we are
subject to examination by taxing authorities throughout the world. Our major tax jurisdictions are
the U.S., Belgium and North Carolina. During 2008, the Internal Revenue Service (“IRS”) completed
an examination of tax years 2002 through 2006 and therefore, tax years prior to
2007 are generally
no longer subject to adjustment. For our U.S. state tax returns, we are generally no longer
subject to examination of tax years prior to 2006 although several jurisdictions have examined
income tax filings through later
years. During 2010, we did not settle any material federal, foreign or state examinations,
however, we are currently being examined by the North Carolina Department of Revenue for tax years
2007 and 2008 as well as the New York State Department of Taxation and Finance for tax years 2007
through 2009. Our foreign income tax returns are generally no longer subject to examination for
tax periods 2004 and prior.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     With respect to tax years that remain open to federal, state and foreign examination, we
believe that we have made adequate provision in the accompanying Consolidated Financial Statements
for any potential adjustments the IRS or other taxing authority may propose with respect to income
tax returns filed. We may, however, receive an assessment related to the audit of our U.S.
federal, state or foreign income tax returns that exceeds amounts provided for by us. In the event
of such an assessment, there exists the possibility of a material adverse impact on our results of
operations for the period in which the matter is ultimately resolved or an unfavorable outcome is
determined to be more likely than not to occur.
</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     We no longer have a “pool of windfall tax benefits” as defined by the authoritative guidance
for stock-based compensation. As a result, future cancellations or exercises that result in a tax
deduction that is less than the related deferred tax asset recognized under the authoritative
guidance will negatively impact our effective tax rate and increase its volatility, resulting in a
reduction of our earnings. As a result of incurring net shortfalls during 2010 and 2008, we
recorded $1.7 million and $3.4 million, respectively, of additional provision for income taxes. We
did not experience any significant shortfalls or windfalls during 2009 associated with stock
compensation.
