ANNOUNCEMENT UPDATE - 2:30pm 9/23 (Taiwan time)

  At the time of this announcement, the Hsinchu Science Park is still without power. However, UMC Group has already begun its inspection and recovery activities wherever possible. We expect that this will shorten the time needed to return to normal production. At present, we would like to report the following developments:

1. Taiwan Power Company estimates that 70% of UMC Group's power requirements in the Science Park will be restored by this afternoon (9/23 Taiwan time). This will allow us to begin the inspection process and make any necessary adjustments to our production equipment, accelerating the return to production.
    
2. UMC Group is already in the process of procuring miscellaneous components, such as quartz furnace tubes, necessary to replace those damaged in the earthquake.
    
3. According to our estimates, after Taiwan Power Company has begun supplying power, it will require three days to complete our inspection and maintenance operations before returning to normal production.

Finally, UMC Group would like to express its support for the families and individuals caught up in this terrible disaster. UMC Group has made a donation of 300 million New Taiwan Dollars to be used to aid the victims of the tragedy. Hopefully, it can help alleviate their pain and grief, and return their lives to normal as soon as possible.

From 9/24 through 9/26, it is a public holiday in Taiwan. Therefore, our next fab status update will be on Monday, Sept. 27th. Thank you for your understanding.
