The position of COO is a newly created position at STATS. As COO, Suh will have
total ownership of the fulfillment function at STATS from planning, purchasing

quality assurance and facilities. Suh's mission is to drive for operational
excellence and best-in-class performance in yield, cycletime, cost and quality.

Prior to joining STATS, Suh was the Managing Director of Philips Semiconductor
Thailand where he managed one of Philips' largest semiconductor manufacturing
facilities with a workforce exceeding 4000 employees. Prior to that, he held
various senior positions in quality assurance and operations at Philips and at
Signetics Korea. Suh graduated with a business administration degree from
Kyung-Hee University in Korea in 1974.

Jeff Osmun, formerly STATS' Vice President of US Sales, has been promoted to
Vice President, Worldwide Sales & Marketing and concurrently President of US
Operations. As Vice President for Worldwide Sales & Marketing, Osmun has the
responsibility for STATS' worldwide sales and marketing efforts, customer
service and technical sales support. His mission is to further deepen

on ensuring that STATS delivers best-in-class customer service.

Osmun joined STATS in 1999 as Director of US Sales. He was promoted to Vice

customer services functions in the US. Prior to joining STATS, he held various
senior positions with Kyocera America, Inc including as National Sales Manager.

University, Pennsylvania in 1985.

Said Tan Lay Koon, "I am delighted that TS and Jeff have accepted these
appointments. They are proven worldclass professionals who have shown
commitment, leadership and dedication in their professional life. TS is a
veteran of the semiconductor industry with more than 25 years of experience in
manufacturing and quality controls. He has a reputation for being a tough-minded
leader with a no-nonsense attitude to operational excellence and quality.

Jeff has made significant contributions to the growth of our US customer base
over the last two years. Under his leadership, the US region has significantly
broadened its customer base. Today, we are actively engaged with more than 60
customers in the US alone. Jeff is a straightforward person and a team player
with a commitment to the highest standards of customer service.

I am indeed excited that with the addition of TS and Jeff, my management team is
in place and STATS is well positioned to deliver worldclass service to our
customers."

"On a separate note, Ong Eng Kian, Executive Vice President, has decided to
leave STATS to pursue his personal interests. His responsibilities will be
assumed by other members of management. I want to thank him for his
contributions and wish him the best in his future endeavors," added Tan Lay
