SUNNYVALE, Calif., March 5, 2002 — Resonate Inc. (NASDAQ: RSNT), the provider of award-winning service level management solutions for business-critical applications, today announced it has expanded its existing technology relationship with Siebel Systems, Inc. (NASDAQ: SEBL), the world's leading provider of eBusiness applications software.

Under the new agreement, Siebel will license Resonate Central Dispatch?, a leading LAN-based traffic management product, for use with the Siebel 7 product. Siebel 7 provides the most comprehensive suite of packaged applications for customer relationship management (CRM) and employee relationship management (ERM), with the lowest total cost of ownership (TCO).
