                    Motorola to Acquire RiverDelta Networks

Strategic acquisition to enable Motorola to offer the broadband industry's most
            advanced,end-to-end IP network infrastructure solutions

HORSHAM, Pa. (July 30, 2001) -- Motorola, Inc. (NYSE: MOT) today announced that
it has entered into a definitive agreement to acquire RiverDelta Networks, Inc.,
a leading provider of carrier-class broadband routing, switching, cable modem
termination system (CMTS), and service management solutions, based in Tewksbury,
Massachusetts. Part of the ongoing strategy of Motorola's Broadband
Communications Sector to offer broadband network operators an end-to-end IP
infrastructure network capable of supporting the latest broadband data, voice,
and video applications, this acquisition adds intelligent, content-aware
networking to Motorola's IP network infrastructure portfolio.

The transaction is valued at $300 million, subject to certain adjustments.
According to the merger agreement, which is subject to various closing
conditions, Motorola will acquire all of RiverDelta Networks' capital stock in
exchange for shares of Motorola's common stock. The final exchange ratio will
not be fixed until immediately prior to the closing and will be based on the
average trading price of Motorola's common stock at that time.

The acquisition will provide Motorola Broadband with RiverDelta Networks'
carrier-class routing platform, integrated, high-density CMTS, and staff of over
200 R&D, engineering, product-marketing, manufacturing, and technical-sales
professionals. Adding these platforms and this expanded technology expertise to
its existing IP infrastructure portfolio will enhance Motorola Broadband's
position as a leader in the CMTS headend space as well as support the company's

strategic growth initiatives in IP data-over-cable (DOCSIS), Voice over Internet
Protocol (VoIP), and IP streaming video. This acquisition also will enable
Motorola to offer a comprehensive solution for metropolitan and regional network
applications and to deploy the integrated broadband-routing platform in
environments using other wired and wireless access media.

Integrating RiverDelta Networks' content-aware routing technologies into
Motorola's existing CMTS business will allow Motorola to broaden its
infrastructure footprint across all system sizes and into regional IP network
applications. Combining the two organizations' resources and collective
expertise is expected to result in a more efficient carrier-class CMTS solution
with integrated routing capabilities for broadband network operators who
currently need additional routers to link the CMTSs deployed across their

Upon completion of the acquisition, Motorola will be poised to offer the
industry's broadest CMTS product family to date, with products ranging from the
high-density solutions that combine high-availability, integrated routing, and
per-flow Quality of Service (QoS) for operators who want to support advanced
services - such as multiple Internet Service Providers (ISPs), Virtual Private
Networks (VPNs) and tiered data services - to modular configurations for
small/distributed networks. This complete suite of IP network infrastructure
products will help enable a variety of operators to capitalize on the new
revenue opportunities arising from the delivery of enhanced IP services to
residential customers and businesses.

"This acquisition makes sense for both companies, because it strengthens our
ability to meet the needs of broadband network operators who are migrating to
high-availability DOCSIS 1.1 networks to deploy complex broadband services like
tiered data-over-cable, VoIP services, and IP streaming video," said Dan
Moloney, senior vice president and general manager of Motorola Broadband's IP
Systems Group. "By combining RiverDelta Networks' best-in-class integrated
routing technology with Motorola's established CMTS business and broadband
network operator sales and support channel, we will now be even more strongly
poised to deliver the reliable, efficient, and cost-effective network solution
that operators require."

"We are pleased and excited to join Motorola Broadband to leverage their
technology in areas such as RF design, VoIP and high-availability systems," said
David Callan, president and CEO of RiverDelta Networks. "We bring new technology
and an entrepreneurial spirit to the table, and we will benefit from the scale
Motorola brings in engineering, sales, and support. Our combined product
offering will give broadband network operators the tools needed to rapidly
deliver innovative new services to their subscribers, for improved customer
satisfaction levels and increased loyalty."
