Cisco Completes the Acquisitions of Monterey Networks and Cocom A/S

SAN JOSE, Calif. -- September 29, 1999 -- Cisco Systems, Inc. today announced it
has completed the acquisitions of Monterey Networks, Inc. of Richardson, TX and
Cocom A/S of Copenhagen, Denmark.

On August 26, 1999, Cisco announced a definitive agreement to acquire
privately-held Monterey Networks, an innovator of infrastructure-class, optical
cross-connect technology that is used to increase network capacity at the core
of an optical network. Under the terms of the agreement, 7.3 million shares of
Cisco common stock worth $500 million was exchanged for all outstanding shares,
options and warrants of Monterey not currently owned by Cisco. In connection
with the acquisition, Cisco expects a one- time charge against after-tax
earnings of between $0.07 and $0.11 per share for purchased in-process research
and development expenses in the first quarter of Cisco's fiscal year 2000.

On September 15, 1999 Cisco announced a definitive agreement to acquire
privately-held Cocom A/S, a leading European developer of high-speed Internet
access solutions over cable, satellite and wireless networks based on
international standards. Under the terms of the agreement, Cisco common stock
worth $65.6 million was exchanged for all outstanding shares and warrants of
Cocom. The acquisition will be accounted for as a pooling of interests.
