eXcelon's dynamic B2B products and services join Cadence's business

processes with partners, suppliers and customers across the Internet

eXcelon Corporation (Nasdaq:EXLN), a leading provider of business-to-business (B2B) eCommerce solutions, today announced that Cadence Network, Inc., the largest Web-based provider of cost management services for multi-site enterprises, has selected eXcelon products and services to build and deploy its B2B partner network. With eXcelon, Cadence will share and automate business processes with its partners, resulting in increased efficiency, better service and lower costs.

Cadence captures various site operating expense information (such as electricity, telecommunications, water, waste management, etc.) and presents that information via the Web, allowing costs to be managed by site, region or division. In essence, Cadence unites fragmented data so national chain executives better understand what they are buying and who they are buying from.

To further automate its cost-saving programs, Cadence will create a B2B partner network, using eXcelon's B2B Integration Server, B2B Partner Server and Xpress. With eXcelon solutions, Cadence can quickly and easily connect any partner to the network, regardless of their size and technical abilities.

The resulting partner network will enable Cadence to conduct B2B commerce anywhere, anytime with any of its business partners.

"Cadence is the market leader in helping multi-location organizations better manage their supplier relationships by providing them with critical information that drives good commerce decisions," said Jim Christopher, chief technology officer for Cadence. "eXcelon's capabilities for creating automated business processes between ourselves and our partners stand out among the competition. As a result, eXcelon makes us even more efficient and allows us to take the relationship our customers have with their suppliers to the next level."

"Our B2B solutions are a perfect complement to the Cadence e-commerce system," said Alan Gold, chief marketing officer and vice president of marketing, eXcelon Corp. "By creating shared business processes across its B2B network, Cadence, its partners and its customers will realize higher levels of efficiency, and most importantly, they will see even greater cost savings."
