Mercator Becomes Newest OASIS Member and Sponsors XML.ORG


 Mercator Broadens XML-to-Any Capabilities With Support for ebXML Initiative


BOSTON, Mass., and WILTON, Conn. – April 27, 2000 – Mercator Software,
(NASDAQ: MCTR), the e-business transformation company™, today became the
newest member of OASIS, the Organization for the Advancement of Structured
Information Standards. Mercator also announced its affiliate sponsorship of
XML.ORG, the OASIS community for advancing XML industry standardization.

In addition, as part of joining OASIS, Mercator is participating in the
Electronic Business XML (ebXML) Initiative.  ebXML was formed  by the United
Nations CEFACT and OASIS to develop a technical framework to enable the use
of XML in a consistent manner across all business data in
application-to-application, application-to-person and person-to-application
environments.  In particular, ebXML lowers the barrier-of-entry to
electronic business in order to facilitate trade, particularly with respect
to small- and medium-sized enterprises (SMEs) and developing nations.
Mercator will take an active role in developing ebXML.

"We’re strong supporters of XML.ORG, an open clearinghouse for XML
specifications," said Dave Power, vice president of marketing, Mercator
Software. "Our customers want to accelerate the integration of their
businesses with their trading partners; OASIS and Mercator are committed to
making this happen by ensuring interoperability of various XML standards for
business-to-business commerce. Joining OASIS and supporting ebXML is an
important step in delivering the most versatile e-business integration
solution while providing our customers with substantial time and cost
savings.”

"By sponsoring OASIS and supporting XML.ORG, Mercator demonstrates its
commitment to product-independent standards for e-business applications,"
commented Laura Walker, executive director of OASIS.  "The XML
community-at-large benefits from the support of XML.ORG by companies like
Mercator who make it possible for OASIS to maintain an unbiased environment
in which the universal data exchange capabilities of XML can be realized."
