Calico Teams with USinternetworking and ZAMBA to Address Demand in

Explosive Business-to-Business Electronic Commerce Market

In response to growing demand among "dot-com" companies, Calico Commerce Inc., (Nasdaq:CLIC), a leading provider of electronic commerce software and services, today announced a focused initiative aimed at meeting the unique needs of emerging leaders in the electronic commerce marketplace.

Digital marketplaces are forecasted to transact more than $1.5 trillion by 2002, according to Forrester Research, and dot-com companies are leading the creation of these new markets. Increasingly dot-com's are choosing Calico eSales as the backbone of their businesses -- most recently in the automotive and education markets. These emerging companies share many of the same requirements as Fortune 1000 companies but also have unique technical and business demands.

Calico is launching a new program that will offer dot-com companies unique product, service, deployment and business terms. The program anchors on Calico eSales products in partnership with USinternetworking, Inc. (Nasdaq: USIX) and ZAMBA (Nasdaq: ZMBA). Together the three companies will provide dot-com companies with best-of-breed eSales solutions that will turbo-charge their selling channel, resulting in reduced time to market, a compelling customer experience and lasting competitive advantage.

"Calico's continued success serving the needs of eBusiness leaders in the Fortune 1000 such as Dell and Cisco, is now extending its reach into the dot-com arena. Our recent successes with OneSwoop.com and edu.com validate the demand for Calico eSales in this important market," said Matt DiMaria, vice president of marketing, Calico Commerce. "We believe these companies, and hundreds like them, are building the digital marketplaces that will dominate the electronic commerce landscape in the years to come. Calico is dedicated to meeting the unique needs of these future digital marketplace powerhouses."

"edu.com is a national marketing and distribution channel that provides college students with best-in-market value on brand-name products and services. Today's college students are absolutely inundated with products choices and 'special promotions' that are often confusing and misleading. In an effort to help students' make educated purchases of complex technologies, edu.com chose Calico eSales to power the Professor, an advanced shopping wizard that will help students find appropriate products based on their needs, experience level and budget," said Paul Pinella, vice president of product development for edu.com. "eSales allows students (and their parents) who are unfamiliar with the intricacies of the computer industry to make meaningful selections tailored to their unique needs. We are confident this feature will result in satisfied customers who, in time, will look to edu.com first when making any significant purchases for school."
