    <TD>Dr.&nbsp;Sun continued &#147;We maintain our previous semiconductor market view as we enter the fourth
quarter of 2011, with unresolved European and U.S. sovereign debt, China inflation, and
limited inventory distribution and digestion visibility through the supply chain all
contributing to industry uncertainty. Accordingly, semiconductor market demand remains weak,
as reflected by our customers&#146; conservative order patterns. During this time, UMC will
continue with its cautious approach. We do anticipate UMC&#146;s rate of revenue decline to ease
in Q4, and will maintain operating profitability as our efforts to strengthen the company&#146;s
operating efficiency and cost structure bear fruit.&#148;</TD>
