[Nasdaq: LEVL], announced today that it has signed a definitive agreement to acquire Acclaim Communications, Inc. located in San Jose, California. Acclaim is a provider of Layer 2/3/4 Fast Ethernet and Gigabit Ethernet switches and Integrated Multi Service Access Products. Under the terms of the agreement, which will be recognized as a pooling of interests transaction, Level One will issue five million shares of common stock in exchange for all outstanding shares of Acclaim. The transaction is expected to close in early July and be accretive to 1999 financial results. This acquisition provides Level One with high performance multi-layer switching and routing silicon technology that will be integrated with Level One's silicon portfolio for networking solutions. In addition, Acclaim's LAN/WAN routing and switching ASIC's, which enable transmission of voice, data, and video over the Internet or over data networks such as Frame Relay and ATM, complement Level One's existing telecom product portfolio. Level One will continue to work with and support Acclaim's customers for existing products with a focus towards becoming the first vendor to provide advanced Networking Systems-on-Silicon for the Intranet and Internet infrastructures. The explosive growth of Internet and Intranet traffic and applications is expected to continue to stress the WAN infrastructure. "The traditional big box routers connecting various backbone segments will have to be replaced by a new generation of Layer 3 switches," according to Dataquest. Non-local traffic is increasing beyond the capacity of traditional routers, creating a need for a more seamless integration of the LAN/WAN interface. Vish Akella, president and CEO of Acclaim stated, "Acclaim's multi-dimensional architecture allows for seamless integration of voice and data, wire speed switching and routing, within the LAN and WAN. Acclaim has embedded application intelligence and bandwidth management into its silicon for the next generation of integrated voice and data networks." 1 "The combination of Level One's Optimal Signal Processing (OSP) transceiver technology and Acclaim's high performance layer 2/3/4 switching and routing technology will set new standards for integration and performance as the LAN and WAN continue to converge," commented Dr. Robert S. Pepper, president and CEO of Level One. "Acclaim's technologies in both the wide area and the local area provide exceptional synergies with our existing market focus in the telecom and network segments.
