Wilton and Old Greenwich, Conn

April 3, 2003 �- Mercator Software, Inc., (Nasdaq: MCTR) and IVANS Inc. today announced an alliance to jointly market a new solution, Mercator Inside IVANSP&C, that will speed the processing of business transactions within the property & casualty insurance industry. Mercator InsideIVANSP&C will make it easy for P&C insurance carriers to automate critical business processes through integration with multiple back-office systems, and enables automatic generation of insurance transactions using the IVANS mailboxing and trading partner infrastructure.

�Mercator brings a new level of automation to the business processes surrounding property and casualty EDI transactions,� stated Anna England, vice president and general manager, IVANS Insurance E-Commerce Solutions. �Working together, we provide our insurance industry customers with packaged solutions to address common EDI business problems that were previously handled in one-off or custom fashion. This will save our customers time and significantly reduce costs, while eliminating errors associated with manual processing.�

IVANS decision to partner with Mercator will provide additional platforms and plug-in components to its customers. In addition, IVANS, the market leader in auto liability X12 reporting, expands its breadth in the X12 transaction processing market, with the ability to offer Mercator�s full capabilities for processing of X12 transactions.

Mercator InsideIVANSP&C leverages Mercator Inside Integrator, combined with IVANS technology to support specific data definitions for the property and casualty messages, as well as integration of IVANS Transfer Manager communications client which reaches over 20,000 agencies currently using IVANS mailbox solutions. In addition, customers benefit from Mercator�s integration expertise as well as IVANS deep industry experience. Mercator chose to partner with IVANS due to their overwhelming leadership in ACORD P&C data translation software and services. The solution will be jointly sold and marketed by both Mercator and IVANS, who will work closely together at the field level as well as in professional services and training to ensure that there is a clear technology and content win for both companies and for the insurance carriers themselves. IVANS reach is broad, with an extensive property casualty customer base.
