"As a well-known Silicon Valley Veteran, Gary has proven experience
driving companies to their next level of growth and global success," said
Lennart Jacobsson, senior partner at CapMan Plc and Silex Microsystems board
member. "We believe his leadership skills will enable Silex to further expand
the high-volume shipments they are delivering today to become one of the
largest and technology-advanced pure-play MEMS foundries in the world."

Most recently, Mr. Johnson was Chairman of Marwood Technology where he
provided strategic advisory services to a variety of US & European Venture
Capital firms, and also to a number of their respective portfolio companies.
Before that, Mr. Johnson was the president and CEO of PortalPlayer Inc., the
leading supplier of low-power application processors for personal media
players including the first Apple iPods. He led PortalPlayer through a highly
successful IPO on NASDAQ in 2004 and later merged the company with NVIDIA.
Previously, Johnson was CEO of S3 Inc., a publicly-traded company on NASDAQ
that became an industry-leading manufacturer of multimedia semiconductors.
During Gary's tenure at S3, the company established a successful joint
venture foundry with UMC in Taiwan. Earlier in his career, Mr. Johnson spent
7 years at National Semiconductor where he founded two wireless business
units. He started his career at British Telecom Research Laboratories at
Martlesham Heath in the UK.

Mr. Johnson replaces Mr. Jan Nerdal who held the position of CEO since
2002 and will retire mid-year. During Mr. Nerdal's tenure, Silex Microsystems
grew from a small lab-based start-up to its current position as a leading
manufacturer of Micro Electro Mechanical Systems (MEMS) on an industrial
scale, with leading customers in Europe, United States and Asia.

"Silex has done an impressive job ramping from a small start-up to a
high-volume MEMS foundry with a strong technology portfolio and an
outstanding reputation in the industry," said Johan Siberg, chairman of the
board for Silex Microsystems. "I want to thank Jan for his tremendous
contributions in bringing the company to this solid market position and we
wish him much success in his future endeavors."

MEMS are complex mechanical and electrical systems built in micro scale
on one single chip. This market is credited with driving innovation in
everyday applications and represents tremendous growth opportunities for pure
play foundries such as Silex Microsystems. According to a recent report by
iSuppli, the MEMS market is expected to grow by 11.1% to 6.5 billion in 2010
and as a leading supplier with strong IP and proven technology, Silex
Microsystems is well positioned for future expansion.

"I look forward to working with the entire Silex team and capitalizing on
the incredible technology and world-class customer base that Silex has
developed over the past ten years," said Gary Johnson, CEO of Silex
Microsystems. "With the company's core technology platforms and applicability
across a broad and diverse set of markets, Silex is well positioned for
strong growth."
