TRADECARD CHOOSES MERCATOR TO STREAMLINE INTERNATIONAL TRANSACTIONS

Wilton, Conn. and New York - December 5, 2000 - Mercator® Software, Inc., (Nasdaq: MCTR), today announced that TradeCard, Inc., an online international trade transaction network for buyers and sellers, has selected Mercator Enterprise Broker as the e-business integration backbone for its international trade solution. Mercator Enterprise Broker will provide TradeCard with scalable integration to streamline international trade transaction processes.

"Our network operations hinge on fast and efficient processing of transactions. Without the ability to translate formats at will, transaction processing could get stalled," said Kurt Cavano, Chairman and CEO of TradeCard. "Mercator provides a flexible, cost-efficient solution that helps us adapt to the systems of our partners and members. As a result of the reduced integration time afforded by Mercator, we can rapidly build our network."

Critical in TradeCard's decision-making process was Mercator's any-to-any data integration and transformation capabilities. With Mercator Enterprise Broker, TradeCard will be able to leverage its network architecture to transform data from X-12 and EDIFACT to XML formats. This enables all parties to an international trade transaction to electronically create, submit, edit and read data about a specific transaction at every step.

"With companies increasingly using the Internet for global e-commerce trading, the ability to translate data from any format is vital," said Jim Schadt, CEO, Mercator. "We are proud that TradeCard turned to Mercator for fast, efficient and accurate integration of its myriad data sets."
