</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US International Trade Commission (USITC)&nbsp;has initiated a Section&nbsp;337 investigation on the
importation of certain semiconductor products into the US. TSMC and Samsung have been named as
respondents in the investigation. TSMC rejects the allegations of infringement by STC.UNM that led
to the investigation, and will vigorously defend against those allegations. STC.UNM has resorted to
litigation in an attempt to improperly extract a license fee.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">TSMC respects the intellectual property of others, but in this case, STC.UNM&#146;s claims are without
merit. We believe the International Trade Commission will agree when it learns all the facts.
