[San Jose, California / Tokyo / London] April 3, 2001 -STMicroelectronics (NYSE: STM) and Hitachi, Ltd. (NYSE: HIT) today announced that they have signed an agreement to establish an independent company, named SuperH, Inc., which will develop and license RISC microprocessor cores of the SuperH^TM family. The new company will license the SH-4 core and all subsequent SuperH cores to the open market, making it easier for customers worldwide to create powerful, cost-effective system-on-chip (SOC) embedded microprocessor (MPU) designs. SuperH, Inc. will also complete final development of the 64-bit SH-5 processor and take over the development of the future SH-6 and SH-7 cores.

Hitachi and STMicroelectronics, both of which are world top-ten semiconductor companies that manufacture and market a broad portfolio of devices, believe that an independently managed entity concentrating on developing and licensing the SuperH family of processor cores will provide significant benefits for systems manufacturers and semiconductor firms. As the new company will be staffed by a highly focused and experienced R&D team and backed by a fully dedicated support organization, SuperH, Inc. will have the resources needed to deliver the high levels of expertise, performance and responsiveness that sophisticated customers demand.

The success of SuperH, Inc. will enlarge the already extensive user base for the SuperH architecture and make it an even more compelling embedded system design choice, particularly for microprocessor-based application-specific products. The potential gains are significant: according to market research firm Gartner Dataquest, the worldwide market for such MPU-based application-specific products should increase by 33% this year and reach 1.4 billion units within four years.

The SuperH family of high-performance 32-bit and 64-bit processor cores is ideally suited for digital consumer, automotive and telecommunications applications. These applications typically require a highly integrated system-on-chip solution that includes a powerful embedded processing engine and can run a wide variety of application software on industry-standard operating systems and middleware.

SuperH, Inc. will have its headquarters in San Jose, California, with operations in Bristol, U.K. and Tokyo, Japan, creating a global R&D network and customer support structure. The Chief Executive Officer of the new company will be Toshimasa Kihara, formerly General Manager of Microcomputer & ASIC Product Operation at Hitachi, and the Chief Operating Officer will be Jean-Marie Rolland, currently R&D Director for MicroCore Development at STMicroelectronics. Initially, around 100 people will be employed by SuperH, Inc., the majority of whom will transfer from Hitachi and STMicroelectronics.

Etsuhiko Shoyama, President and Director of Hitachi, Ltd., said: “The new company will have the necessary mandate, resources and focus to take the SuperH family of processor cores to the open market. It will make the SuperH architecture the de facto standard in digital consumer, automotive and telecommunications. By leveraging the outstanding combination of price, performance and power that SuperH CPUs offer, from the SH-4 series upwards, SuperH, Inc. will make the cores compelling choices for leading-edge customers contemplating advanced system-on-chip designs.”

Pasquale Pistorio, President and CEO of STMicroelectronics, said: “The establishment of this new company is the culmination of the excellent relationship that STMicroelectronics has enjoyed with Hitachi over the past few years to develop leading-edge microprocessor cores for system-on-chip applications. The SuperH architecture already enjoys a significant market presence, especially in the digital consumer and automotive segments. SuperH, Inc. will build on this strength and really play a leading role in the fast growing embedded RISC processor market.”

Both STMicroelectronics and Hitachi are contributing the necessary intellectual property rights, human resources and financial assets that SuperH, Inc. needs to start its operations. Initially, the new company will be jointly owned by Hitachi and STMicroelectronics and managed as an independent entity. The Board of Directors of the new company will comprise four members from Hitachi and four members from STMicroelectronics. A strategic round of investment is planned following incorporation.

Hitachi and STMicroelectronics have been promoting the SuperH architecture together and jointly developing the SH-5 core in a close relationship since 1998. In October 2000, the companies also announced plans to jointly develop the SH-6 and SH-7 cores.

The contemplated transaction is subject to certain regulatory approvals. STMicroelectronics and Hitachi expect the transaction to close within the quarter.
