Quadstone Successfully Integrates the Quadstone System with Siebel 2000

Boston, MA-December 3, 2001-Quadstone, a leading provider of predictive
marketing software and services, today announced that the integration
between its Quadstone System version 3.0 and Siebel eBusiness
Applications version 6.0 has been successfully validated by Siebel
Systems.  Siebel Systems, Inc. (Nasdaq: SEBL) is the world's leading
provider of eBusiness applications software.  The Siebel Validation
Program applies rigorous technical scrutiny to evaluate the integration
of third-party solutions with Siebel eBusiness Applications.

The Quadstone System helps business users more efficiently and
accurately predict what products customers will buy, what promotions
they will respond to, which customers are under threat of defecting, and
which customers have the potential to be more profitable.

Siebel Systems provides an integrated family of eBusiness applications
software, enabling multichannel sales, marketing, and customer service
systems to be deployed over the Web, call centers, field, reseller
channels, retail and dealer networks.  The Quadstone System integrated
with Siebel eBusiness Applications leads to more accurate and valuable
rules that drive more targeted customer interactions, leading to
increased customer satisfaction, customer loyalty and customer
profitability.

The integrated solution generates customer selections, rules, scores,
and segments using Quadstone's predictive marketing solutions and sales,
service, and marketing data stored in the Siebel eBusiness Applications
database.  The customer selections, rules, scores, and segments are then
used within specific Siebel eBusiness Applications products, such as
Siebel Systems' closed-loop marketing solution, Siebel Marketing, to
optimize targeting strategies and future customer interactions.

The Quadstone System employs the Quadstone Connector for Siebel
eBusiness Applications to integrate with Siebel Marketing via the
Siebel Analytical Adapter, the Siebel Systems external data-mapping
interface that enables the integration of external analytical data
with the Siebel eBusiness Data Warehouse.  The Quadstone Connector for
Siebel eBusiness Applications also supports direct integration with
other operational applications such as Siebel Call Center, Siebel
Systems' market-leading application for call centers, via Siebel
Enterprise Integration Manager (EIM) and the Siebel eBusiness
Applications user interface configuration.  The Quadstone Connector
for Siebel eBusiness Applications is available for NT and UNIX
platforms and supports DB2/UDB, Oracle, and Microsoft SQL Server
databases.
