            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.
