Morgen-Walke Associates John Kehoe Jeannine La Pietra/Chris Danne Chief Financial Officer (415) 296-7383 (916) 855-5000 Patricia Walsh (212) 850-5600 LEVEL ONE COMMUNICATIONS TO ACQUIRE JATO TECHNOLOGIES ----------------------------------------------------- Acquisition of high performance Gigabit Ethernet controller technology and IP software expertise further strengthens leadership in the deployment of Gigabit Ethernet over Category 5 Copper Wire SACRAMENTO, Calif.--November 9, 1998--Level One Communications, Inc. (Nasdaq: LEVL) announced today that it has signed a definitive agreement to acquire Jato Technologies, Inc. located in Austin, Texas. Jato is a silicon provider of high performance, multi-speed Gigabit Ethernet controller technology and has recently commenced initial shipments of their first product. Under the terms of the transaction, which will be accounted for as a pooling of interests, Level One will issue shares that total approximately $80 million in exchange for all outstanding equity interests of Jato. The transaction is expected to close before the end of November and be slightly accretive to 1999 financial results. The acquisition of Jato's business provides Level One with Jato's high performance, multi-speed Gigabit Ethernet controller technology as well as expertise in implementing complex network algorithms and protocols, such as Transmission Control Protocol/Internet Protocol (TCP/IP) in silicon. In conjunction with its multi-speed Gigabit physical layer technology, this capability will give Level One the opportunity to provide complete, high performance, low-cost solutions for 10/100/1000 Mbps Ethernet over Category 5 copper wire. Moreover, this transaction complements Level One's recent acquisition of Acclaim Communications. Level One now has a complete portfolio of silicon solutions for bus-to-bus networking including multi- layer switching and routing ASICs for the transmission of voice, data, and video over Ethernet LANs as well as other wide area data networks such as Frame Relay and ATM. With the explosion of Internet/Intranets, Level One is poised to expand its position as a leading supplier of mainstream data networking technologies. "Our strategy is to deliver end-to-end, Networking Systems-on-Silicon and this transaction represents Level One's latest step in the execution of this strategy," commented Dr. Robert S. Pepper, president and CEO of Level One. "Jato's advanced Gigabit Ethernet controller technology coupled with their expertise in TCP/IP and high performance driver design, will be a critical enabler for wide acceptance of Gigabit Ethernet over Category 5 copper wire. We are excited that they have become a part of the Level One family." "Level One and Jato share the vision of providing high performance, affordable solutions that accelerate the development and deployment of Gigabit Ethernet over Category 5 copper wire," said Walter Thirion, president and CEO of Jato Technologies. "Jato has been focused on evolving the network interface to a higher level of intelligence and Level One is the clear winner in physical layer devices. The combination of Jato and Level One will be a powerful force in the emerging 100/1000 Mbps Ethernet over Category 5 copper market." Michael Dell, a participant in Jato's last financing round through a personal investment, was enthusiastic about the acquisition. "Jato Technologies and Level One are demonstrating the technology leadership necessary to enable 100/1000 Mbps Ethernet for standards-based servers and workstations," Dell said.
