SAGENT AND DSET PARTNER TO DELIVER REAL-TIME DSL LOOP
PRE-QUALIFICATION FOR TELECOM INDUSTRY

Sagent's eServices automates customer pre-qualification and adds accurate geographic data for precise and timely deployment of DSL service

MOUNTAIN VIEW, Calif.-May 15, 2000-Sagent Technology Inc. (Nasdaq: SGNT), a leading provider of Real-time e-Business Intelligence solutions, today announced a strategic partnership with DSET (Nasdaq: DSET), a leading provider of business-to-business e-commerce connectivity solutions for the global telecommunications marketplace, to enable telecommunications companies to quickly and efficiently determine a customer's qualification for digital subscriber line (DSL) service.

Through the partnership, Sagent's eServices solution will be integrated into DSET's ezDSL Leads Qualification System, allowing telecommunications companies to facilitate the real-time pre-qualification of customers for DSL service based on a customer's geographic information. Sagent maximizes the accuracy and value of telecommunication companies' customers and prospects information by seamlessly verifying across multiple platforms, including the Internet, correct address information, adding widely available third-party demographic data, and performing spatial analysis from the service point to the customer's destination. By doing so, the telecommunications customers' proximity to the local exchange service is determined, enabling more precise and timely deployments of DSL service.

"We chose to partner with Sagent because its proven spatial analysis tools and real-time geographical data are the most accurate available," said Vikas Trehan, senior product manager, DSET. "Together, we are able to offer telecommunications customers a single, comprehensive solution for ordering DSL through one vendor. By automating the entire pre-sales process for DSL ordering, we are able to offer a higher level of customer service which DSET customers expect."

The Sagent Solution allows businesses to collect and analyze customer and operational data from existing systems and to incorporate the most current geographic, business-to-business and demographic information from third-party content providers in real time. This information is then made available over the Web via a secure connection to create precise one-to-one marketing campaigns, identify profitable sales opportunities, and improve operational efficiencies.
