         A press release dated September 20, 2000 announcing that
STMicroelectronics has completed its acquisition of Waferscale Integration, Inc.




PR No. C888M STMicroelectronics Completes Acquisition of Waferscale Integration, Inc. Complementary portfolio of innovative Flash-based Programmable System Devices reinforces ST's strategy in Memory Systems Geneva, September 20, 2000 - STMicroelectronics (NYSE: STM) today announced that it has completed the acquisition, effective September 18, 2000, of Waferscale Integration, Inc. (WSI), the Fremont, California-based leader in Programmable System Devices (PSDs). In addition to the acquisition, which was announced last July, ST has obtained the product portfolio, intellectual property (IP), know-how and technologies developed by WSI in the field of Non-Volatile memories and memory systems. WSI's operations will continue to be headquartered in the Silicon Valley area, but will now function as a fully-fledged operational Business Unit within STMicroelectronics' Memory Products Group. "We had been working with WSI as a design and manufacturing partner for several years and, the integration of WSI's human and intellectual resources into ST's structure will result in a seamless transition for WSI's fast-growing customer base while exploiting the synergistic potential for further development of WSI's innovative products," said Carlo Bozotti, Corporate Vice President and General Manager of ST's Memory Products Group. "ST's world-class strengths in manufacturing, products support and development will not only result in enhanced service to our current customer base, but also make PSDs attractive to new high volume customers," noted Reza Kazerounian, manager of the new Business Unit within STMicroelectronics. The addition of WSI's IP portfolio and its design, marketing, application and software teams to ST's existing worldwide resources reinforces the Company's strengths in Memory Systems, where it already offers numerous application-specific memory architectures, as well as complementing its established strengths in the field of standard memories.
