IXYS announces acquisition of ZILOG

Biel, Switzerland and San Jose, CA. December 7, 2009 - IXYS Corporation (NASDAQ: IXYS), a market leader in power semiconductors and specialized mixed signal IC products, today announced that it has entered into a definitive agreement to acquire Zilog, Inc. (NASDAQ: ZILG), a trusted supplier of application specific, embedded microcontroller units (MCUs) that are system-on-chip (SoC) solutions for industrial and consumer markets. Under the terms of the agreement, IXYS will acquire all of ZilogТs outstanding common shares for $3.5858 per share in cash, or approximately $62.4 million. The acquisition is subject to the approval of Zilog shareholders and other customary closing conditions. The transaction is expected to be completed during the quarter ended March 31, 2010.

The combination of the two companies with complementing technologies will allow IXYS and Zilog to leverage analog power management with digital control. Zilog has a focused MCU business with technologies that will complement IXYSТ product portfolio. IXYS has a broad based and diversified range of products geared toward industrial, telecommunications, medical, automotive, alternative energy and consumer applications. By introducing MCUs that enable digital power management and embedded control, IXYS will be able to create more cost-effective system integration solutions for its diversified customer base.

"As the world migrates toward SoCs, ZilogТs core microcontroller technology along with IXYSТ core power solutions create entirely new products that will meet the needs for today and tomorrow," said Dr. Federico Faggin, Chairman of the Board and the co-founder of Zilog, Inc.

"We are pleased with this strategic acquisition that will allow us to penetrate more applications in traditional and developing markets, leveraging both of our strengths. Digital power management is one of the fastest growing applications in the markets we serve. ZilogТs 35-year history in microcontrollers with its legendary Z80 and Z8 architectures parallels IXYSТ pioneering technologies in power MOSFETs, IGBTs and HVICs," commented Dr. Nathan Zommer, CEO and Founder of IXYS Corporation. "With the expected rebound in MCU sales in 2010, we anticipate a growth in opportunities for refined power control in many applications; the acquisition and integration of this MCU business will strengthen our position and allow us to take advantage of these opportunities. We believe this transaction will create further value for our shareholders, employees and customers through a further expansion and diversification of our product offerings. As it is one of the pioneers of MCUs in Silicon Valley, we plan to keep the Zilog entity with its recognized and valued trademark."

"Zilog has actively explored a broad range of strategic alternatives to enhance shareholder value. The price that IXYS is proposing to pay is a premium to our current stock price, as well as a substantial premium to the average of the prices at which weТve traded throughout 2009," said Darin Billerbeck, ZilogТs president and chief executive officer. "This acquisition brings liquidity to our shareholders, while increasing our financial stability in these continuing uncertain economic times."

IXYS expects to increase its penetration in the automotive electronic and electric market by producing cost-effective integrated product offerings, including the power semiconductors, driver ICs and Zilog MCUs that are essential for automotive controls and driving displays. In IXYSТ prime industrial market, IXYS plans to deploy MCUs that are suited for motor control, power control and automation. In the telecommunications and security industries, ZilogТs MCUs complement IXYSТ ICs, which can be deployed in modems, VOIP, FIOS and automated alarm systems. For the medical market, the Zilog MCU platform complements IXYSТ power and IC products in defibrillators, imaging and diagnostics. Additionally, the recently expanded IXYS products for LED lighting and display, which require digital power control, will benefit in the market from the availability of complementary MCUs. MCU product offerings will be expanded to include low-power and sensing technologies for energy management applications, including smart lighting and intrusion detection.

In addition to expanding market opportunities, the acquisition will allow IXYS and Zilog to pool R&D resources, leverage economies of scale, reduce manufacturing costs and streamline and integrate operational and support costs. Over time, the integration is expected to result in improved financial results for the combined organization.
