    <TD>Dr.&nbsp;Shih-Wei Sun, CEO of UMC, said, &#147;In 3Q 2012, both UMC&#146;s revenue and operating profit
continued to grow. Wafer shipments reached 1.13&nbsp;million 8-inch equivalent wafers, with
overall capacity utilization at 84%. Increased 40nm revenue contribution led to higher average
selling price, which contributed to 3Q revenue growth. With the share of 40nm sales growing
from 9% to 13% quarter-over-quarter due to solid 40nm chip demand, we anticipate our 15%
year-end internal revenue target from 40nm to be achieved ahead of schedule. In addition to
40nm, we are providing our customers with the most competitive and innovative embedded flash
specialty technologies for the rising touch-sensor chipset market. This platform has been
successfully adopted by numerous industry leading customers with many products currently in
mass production. We are optimistic that these specialty technologies will inject UMC with new
growth momentum in the coming future.&#148;</TD>

    <TD>Dr.&nbsp;Sun continued, &#147;28nm progress is within our expectation, with yield enhancement of design-in
products continuing to improve. For first-wave 28nm product matching business, we are seeing
evident yield progression for ported ICs after adjusting our process and device parameters
during recent months. UMC also successfully taped out a mobile communication product in 3Q
using our 28nm high-k/-metal-gate (gate-last) process. We are subsequently collaborating
closely with customers for their 28nm mobile communication & computing, wired & wireless
connectivity, DTV, data storage controller, and programmable logic products. Meanwhile, based
on our IBM FinFET licensing, UMC has decided to aggressively develop 14nm FinFET technology on
20nm metal. 14nm FinFET will deliver the most optimal low-power and high-performance solution
to offset the cost impact from using double patterning lithography.&#148;</TD>

    <TD>Dr.&nbsp;Sun added, &#147;Foundry is prone to both inventory correction and industry cycles. We expect the
present inventory adjustment to continue into early next year. The momentum of the demand
recovery in 2013 will be determined by macroeconomic conditions, end demand strength and the
transition progress for new products entering the market. In the meantime, UMC will continue
to enhance its customer composition and product mix, and further exercise flexible capacity
deployment to accommodate evolving production requirements. UMC is also strengthening its
tailored cooperation with leading-edge and specialty technology customers for specific
products and applications to provide a full-range of &#145;Customer-Driven Foundry Solutions.&#146;&#148;</TD>
