MOUNTAIN VIEW AND SAN JOSE, Calif.--(BUSINESS WIRE)--May 23, 2000

CyberSource (NASDAQ:CYBS), a leading provider of mission-critical eCommerce transaction services, today announced a strategic alliance with Calico Commerce, Inc. (NASDAQ:CLIC), a leading provider of eBusiness applications that enable companies to sell over the Web. Calico Commerce will integrate the CyberSource Commerce Component into its Calico Market Maker(TM) solution. The relationship provides Net marketplaces with complete, plug-and-play eCommerce transaction services that require virtually no systems integration, resulting in faster time to market.

Calico Market Maker is a robust B2B solution designed to power digital marketplaces, with rich out-of-the-box functionality that supports multiple buyers and suppliers and offers Net Market Makers unparalleled speed-to-market. Calico's open and scalable architecture allows customers to quickly and easily incorporate additional business services such as the CyberSource Payment Service for B2B customers. With the CyberSource Commerce Cartridge for Calico, B2B customers can process electronic checks, purchasing cards, credit cards, as well as perform fraud screening, verify delivery addresses, and perform tax calculations in the US, Canada and Europe--all in real time.

"In an environment where time-to-market is of critical importance, Calico and CyberSource provide fast-track solutions for Net markets," said Erna Arnesen, vice president of North American Field Operations for CyberSource. "Our technology provides support for online credit card transaction capabilities within days, enabling marketplaces to set up shop immediately."

"Calico Market Maker functionality is critical for organizations wanting to build communities by grouping appropriate buyers and sellers online, and grow their businesses by successfully meeting the expanding requirements of digital marketplaces," said Matt DiMaria, vice president of marketing for Calico Commerce. "As we continue to grow our Net markets customer base, we look forward to working with CyberSource, a partner that will scale with our business to provide the reliable technology that will transform the way customers process transactions."

The Net Markets Alliance adds value to Net Market Makers by allowing them to focus on building their business, rather than expending the time and resources necessary to effectively evaluate the multiple offerings in the marketplace. The alliance also helps ensure that each solution works seamlessly and also provides the flexibility to expand with their marketplace momentum.
