Oak CEO Young Sohn Chosen as Part of Hyundai's Effort to Build a

Globally Balanced Board

Oak Technology, Inc. (Nasdaq:OAKT), a leading provider of embedded software and semiconductor solutions for the digital imaging and optical storage markets, today announced that Oak President and CEO Young Sohn has been elected to the board of directors of Hyundai Electronics Industries (Seoul, South Korea). Sohn's election is part of a strategic move by Hyundai Electronics to balance its board, integrating key outsiders that possess international expertise in a variety of fields and thereby boosting the company's global perspective and competitiveness. With a background encompassing finance and engineering, as well as high-level stints with U.S.-based Quantum Corp. and Intel Corp., Sohn was viewed as integral to helping Hyundai Electronics achieve this objective.

Said Dr. Chong-sup Park, president and CEO of Hyundai Electronics Industries, "We are pleased to welcome Young Sohn to our board. The strategic vision and leadership he has exhibited throughout his career in a variety of technology sectors -- and particularly as an influential member of the Silicon Valley community -- exemplify the contributions that we anticipate as our companies become more closely allied."

Sohn became president and CEO of Oak Technology in February 1999. Prior to joining Oak, Sohn was president of Quantum's hard-drive business; before that, he was a senior executive with Intel. Other boards on which he currently serves include those of U.S.-based firms PLX Technology and Earjam.com (a provider of Internet music content in which Oak holds a 43-percent share), the Asian American Manufacturers Association, and the Massachusetts High-Technology Council. Sohn received his MBA from the Sloan School of Management at Massachusetts Institute of Technology (MIT), and holds a BSEE degree from the University of Pennsylvania.

Both Hyundai Electronics and Oak Technology have made recent announcements that point to the companies' shared dedication to technology innovation and advancement. Last month, Hyundai announced that it had developed, using 0.14-micron technology, the world's smallest 256M dynamic random-access memory (DRAM) chip -- 40 percent smaller than currently available synchronous DRAMs.

Earlier this week, Oak Technology unveiled key additions to both its imaging and optical product lines. emPOWER, a fully integrated hardware/software controller solution, is designed to significantly reduce time-to-market and cost dynamics for printer and multifunction peripheral (MFP) manufacturers. The OTI-9820/2650 is a two-chip solution that incorporates all major digital versatile disk (DVD) player functions onto two complete systems-on-a-chip, or SOCs. The new chipset's aim is to help original equipment manufacturers bring advanced DVD players to market rapidly and cost-effectively and thereby help speed the adoption of DVD worldwide, including regions where video CDs currently prevail.
