Andersen Consulting and Calico Join Forces to Help Companies Create Personalized Web-Based Buying Experiences for Their Customers.

NEW YORK--(BUSINESS WIRE)--Sept. 20, 1999--

Andersen Consulting and Calico Commerce, Inc. today announced a global business alliance to help organizations engage in eCommerce by enabling them to use Internet technologies to create personalized online relationships with their customers.

Andersen Consulting, a leading global management and technology consultancy, and Calico Commerce, will team to deliver solutions that improve an organization's ability to provide goods and services based on customers' personal buying preferences via the internet.

Under the agreement, Andersen Consulting and Calico will initially focus on providing internet-based customer relationship management solutions, using Calico's eCommerce software, to financial services, telecommunications, and electronics and high tech companies as well as a variety of retail and manufacturing organizations.

It was also announced that Andersen Consulting has expressed an interest in making an equity investment in Calico's initial public offering.

"Buying more complicated products and services tailored to individual preferences -- such as financial services packages, computers and complete travel experiences -- is the next evolution of sophisticated consumer purchasing on the Web," said Philip Tamminga, a partner in Andersen Consulting's Customer Relationship Management practice. "Organizations that offer customers a guided selling experience which allows them to take control of the online buying process will benefit from larger near-term sales, and repeat business."

"This alliance couples Andersen Consulting's strong eCommerce and customer relationship management expertise and offerings with Calico's customer driven software for eCommerce," said Beverly Powell, vice president of business development, Calico. "Together we will provide large organizations with electronic commerce software applications that enable reduced time-to-market for new products, and improved sales effectiveness."
