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."
