FOR IMMEDIATE RELEASE

SILICON GRAPHICS (SGI) STANDARDIZES ON SILICOM
GIGABIT ETHERNET ADAPTERS

— SGI, Silicom’s Top Tier Customer for Multiport Gigabit Adapters,
Continues To Place Orders —

        KFAR SAVA, Israel – June 21st, 2004 – Silicom Ltd. (NASDAQ:SILCF) today announced that Silicon Graphics Inc. (NYSE: SGI), a top-tier developer and manufacturer of high-performance server-based platforms, has standardized on Silicom’s cutting-edge Gigabit Ethernet Server Adapters, and has placed additional orders for these leading products.

        In November 2003, SGI selected Silicom’s Gigabit Ethernet adapters for use in its servers, marking the successful end of a rigorous technology evaluation and qualification process. After working together with Silicom to customize the products for its high-end IRIX® systems, SGI placed its first orders, and since then has already purchased more than 800 units. In addition, Silicom has now learned that SGI has standardized on the advanced Silicom products.

        With annual revenues of nearly $1 billion, SGI is the world’s leading developer of high-performance computing, visualization, and storage systems. Its cutting-edge systems eliminate the bottlenecks that characterize a growing number of advanced high-performance computing (HPC) and advanced visualization environments.

        “We are proud of the relationship we have built with this technology powerhouse, and delighted that it has singled us out for distinction,” said Shaike Orbach, Silicom’s President and CEO. “We believe SGI’s standardization on our strategic Server/Storage adapter products has the power to significantly enhance our sales, helping us to mitigate the impact of declining sales of our legacy products.”
