SANTA MONICA, Calif.--(BUSINESS WIRE)--May 4, 1999--

ISOCOR (Nasdaq:ICOR), a leading Internet messaging and directory software developer, Tuesday announced a series of marketing initiatives in association with Network Appliance Inc. (Nasdaq:NTAP), a leading provider of network-attached storage and data-access solutions.

Used in combination by ISPs, ISOCOR's N-PLEX message server and Network Appliance(TM) filers (file server appliances) deliver a winning combination of the world's fastest and most scalable Internet messaging server and extremely cost-effective and high-performance networked data-access and disk storage.

"An ISP's ability to grow depends on providing thousands or even millions of new customers with market-leading messaging performance and ease of use," noted Paul Gigg, president and CEO, ISOCOR. "This implies both performance on the server and the availability of massive, high-performance storage."

NetApp(R) filers deliver fast, reliable network data access in application environments ranging from the workgroup to the enterprise. By combining NetApp's powerful Data ONTAP(TM) software with optimized appliance hardware, NetApp filers deliver exceptional performance and high data availability with unprecedented ease of use.

"We are very happy with the way that N-PLEX messaging makes efficient use of the capabilities of our filers," added Andy Watson, director of Architecture & Deployment.

"We recognize that massive, consolidated, and vendor-independent storage is vital to ISPs, who must cope with growing demands from Internet users, who increase storage requirements every day. ISOCOR, together with NetApp, can provide ISPs with a real competitive edge."
