SAN JOSE, Calif. -- July 28, 1997 -- Cisco Systems, Inc. today announced it has signed a definitive agreement to purchase the Dagaz xDSL business of Integrated Network Corporation (INC) for approximately $108 million in cash and the assumption of the xDSL business option plan with approximately 230,000 shares of Cisco stock (worth approximately $16.5 million based upon Ciscos July 25 closing price of $79.6875). INC, based in Bridgewater, New Jersey, is a broadband networking company providing a suite of products for high speed information transmission over existing copper phone lines.

Under terms of the purchase, Cisco will acquire INCs Dagaz xDSL products and intellectual property, personnel, and other xDSL-related assets. In connection with the transaction, Cisco expects a one-time charge against after-tax earnings of between $ .08 and $ .11 cents per share in the first fiscal quarter of 1998.

The purchase has received board approvals from each company and is expected to be completed in August subject to various closing conditions including approval under the Hart Scott Rodino Antitrust Improvements Act.

Cisco To Offer Service Providers Advanced Digital Subscriber Line Technology

Customer demand for high speed information transmission using the Internet, graphics-heavy web sites, networked commerce, teleworking and integrated voice, video and data services is escalating. Using the existing telephone system, xDSL is poised to solve the problem of high-speed access to many of these networked applications while offloading the public switched telephone network. Service providers believe xDSL will offer an affordable mechanism to satisfy bandwidth hunger and supply new high-speed networking services without large capital outlays.

"We believe Ciscos leadership end-to-end solution, with additional NEBS compliant xDSL, offers great potential," said Joe Zell, president of US WEST !nterprise. "Subscriber link technology, underscored by todays news, will help U.S. West fuel the market acceptance of new xDSL services resulting in market acceleration."

"From xDSL to dial services and all points in-between, GTE is a firm believer in Cisco Powered Networks," said Lewis Wilks, president of GTE Communications. "Ciscos commitment to a carrier and premise xDSL platform will help us deploy both business and residential services quickly. The purchase of the Dagaz business, combined with Ciscos xDSL internal development, will give users a new carrier compliant fast lane on their networks."

This acquisition brings both a leading density DSL central office concentrator (Jera) and subscriber side unit (Thurisa) to Ciscos product portfolio. At the central office site, Dagazs Jera is a carrier class xDSL Access Multiplexer (DSLAM) capable of speeding traffic onto an ATM-based network to reduce network congestion. Jera takes this one step further with high density voice splitting technology and plans to condense numerous network traffic feeds into a single line. This DSLAM also offers upgradeable line cards offering investment protection during the current period of evolving modem standards.

Cisco also has several options today for delivering xDSL in subscriber sites. Dagaz recently announced immediate availability of the Thurisa xDSL customer premises device. The Cisco 700 series also offers xDSL to connect end-users with networked applications at near-LAN speeds over the worlds more than 700 million telephone lines.

The approximately 30 employees of Dagaz will continue to work in New Jersey, and will eventually relocate to Ciscos Chelmsford, MA facility. All employees, including Dagazs President and COO Dr. Dev Gupta, will become part of the Network to User Business Unit headed by Vice President and General Manager Kevin Kennedy within Ciscos Service Provider line of business.
