<P align="left" style="font-size: 10pt"><FONT style="font-size: 12pt">To respond to the news reported by Apple Daily on September&nbsp;23, 2008 about rumors that UMC
plans to lay off 1,300 employees due to a slow economy, UMC would like to announce the following:
</FONT>

<P align="left" style="font-size: 12pt">1.&nbsp;Contrary to the rumors, UMC has no plans to reduce any set number or percentage of its
headcount. UMC&#146;s workforce is determined by the needs of the company&#146;s development as well as
employee performance. To address the current economic situation, UMC plans to be more conservative
when recruiting new employees. However, UMC will continue to hire for positions that contribute to
the company&#146;s long-term competitiveness, such as R&#038;D engineers.


<P align="left" style="font-size: 12pt">2.&nbsp;UMC will not shut down any fabs. During this temporary slowdown in market demand, UMC will
continue to implement cost-saving measures; however there are absolutely no plans to close any of
UMC&#146;s fabs.


<P align="left" style="font-size: 12pt">3.&nbsp;With good operating cash flow, sufficient cash and low debt, UMC is well-positioned through this
economic slowdown and expects to be well prepared for the next economic recovery.
