SAN JOSE, Calif.--(BUSINESS WIRE)--Aug. 6, 2001

Network Advisor(TM) Enables Component-Based Modeling for

Rapid Configuration of Highly Complex Products and Services

Calico Commerce, Inc. (Nasdaq:CLIC), the technology leader in interactive selling software, today announced the availability of Network Advisor(TM) 3.5, a 100% Pure Java application that extends the company's advanced configuration and recommendation engine, Advisor(TM) to handle the most complex configuration problems. Network Advisor is designed to enable companies to configure highly complex products and services quickly, accurately and cost-effectively through its unique component-based modeling capability. Multiple selling channels can be served simultaneously, maximizing a company's sales effectiveness.

Network Advisor is also the only interactive selling solution that ships with templates for the telecommunications industry, making ATM/Frame Relay, DSL and IP-VPN Network configuration fast and effective to deploy. Companies using Network Advisor will realize significant ROI by using a comprehensive configuration solution that delivers fast time-to-market and a low total cost of ownership.

"Selling complex products and services with 100% accuracy is imperative in today's competitive communications market. This ability is elusive to most companies due to the broad and complex nature of their offerings and the limitations of traditional configuration solutions, none of which could deliver the critical functionality we needed in our complex business," said Hans Rietkerk, CEO of Dutch broadband provider, BBned. "We expect Calico's interactive selling solution, and its Network Advisor product specifically, to help us overcome the obstacles to achieving this goal and deliver bottom-line benefits such as increased revenues through higher average selling prices and increases in repeat-customer sales."

Calico Network Advisor is based on Calico's open standards-based Java platform. Unlike other available solutions, Calico Network Advisor allows:

-- Component-based configuration - Competing solutions require companies to
build large, monolithic models to configure complex systems. Network Advisor
allows individual components, for example, servers and storage units, to be
built separately and combined as needed, for example, in a clustered
environment, and re-used in multiple models, providing greater modeling
flexibility, superior performance, and faster development and roll-out of
complex systems

-- Simultaneous Multi-User Configuration - Some companies, especially in the
communications industry, must provide access to multiple simultaneous users,
for example, to manage different parts of a corporate network. Only Network
Advisor enables real-time multi-user, multi-node configurations, propagating
constraint logic automatically, thus ensuring that the entire network and all
nodes are accurately configured.

-- Move, Add, Change and Delete Order Tracking - Companies suffer high costs,
lost time and customer dissatisfaction when they cannot accurately track a
customer's history to ensure that new orders are compatible with existing
customer installations. Network Advisor's unique "MACD" capability tracks
changes, additions and deletions to configured systems, and provides historical
versioning, ensuring that every new or change order is 100% accurate and can be
provisioned and billed appropriately.

-- Visual Modeling Environment - Companies using Network Advisor create model
components using Calico's unmatched drag-and-drop visual development and
real-time testing environment, greatly speeding up deployments, and lowering
the total cost of ownership. Other solutions rely on extensive coding in
proprietary languages, and building test pages by hand, resulting in long and
costly deployments and maintenance.

-- Communications Services Templates - Calico's industry-specific template
comes ready for rapid development and deployment of ATM/Frame Relay, DSL and
IP-VPN Network configuration models.

"Calico has demonstrated a solid commitment to the telecommunications industry over the last two years with its industry-specific offerings, attracting leading carriers such as KPN and up-and-comers such as BBned," said David Hawley of the Yankee Group. "With the current release of Network Advisor, Calico raises the bar in complex configuration, offering unique component-based, multi-user and 'move, add, change, delete' capabilities that are critical to addressing the interactive selling needs of the telecommunications industry."
