ARBORTEXT ANNOUNCES ALLIANCE WITH EXTENSIBILITY

Extensibility’s XML Authority to be Integrated into Arbortext’s Epic Content
Management Solution

ANN ARBOR, Mich., June 13, 2000 -- Arbortext, Inc., a leading provider of
Extensible Markup Language (XML)-based e-content software for e-publishing,
e-commerce, and B2B e-marketplaces, and Extensibility, Inc., the leader in
XML schema management solutions, today announced a technology and marketing
alliance.  XML Authority, Extensibility’s premier solution for the creation
and management of XML Document Type Definitions (DTDs) and schemas, will be
integrated within Arbortext’s industry-leading Epic e-content management
solution.  With Extensibility’s technology embedded within Epic Architect,
end users benefit from an intuitive and user-friendly graphical tool to
design and build DTDs.

The integration of XML Authority into Epic Architect’s user interface
enables customers to use free-form editing in Epic Editor or Epic Editor LE
(Light Edition) to perform rapid prototyping.  This rapid prototype feature
helps reduce development time by up to 80% over traditional methods.  The
Arbortext and Extensibility alliance also enables users to convert SGML DTDs
to XML DTDs, or any other commonly used XML schema dialect, through
Arbortext’s Epic e-content software.

Arbortext has tested the integration of XML Authority with Epic Architect to
ensure its compatibility with Arbortext-supported DTDs and methodology.  The
integration of XML Architect into Epic Architect is seamless; providing
Arbortext customers with all the benefits and features of Epic Architect and
XML Authority without having to work with multiple vendors.

“The integration of Extensibility’s technology into our established content
management solution enables organizations to design, develop and deploy DTDs
at a much quicker speed than just a short time ago,” said Dave White,
director of business development of Arbortext.  “This combination will
provide customers with a powerful, easy-to-deploy solution for developing
and managing critical e-content.”

“We are delighted to be working with Arbortext.  Combining our technologies
will provide organizations full context to the content which is key for
automated business-to-business information interchange,” said Reid Conrad,
president and CEO of Extensibility.  “Solutions such as Arbortext’s Epic
Architect and our XML infrastructure asset management solutions are becoming
the foundation of next generation e-business applications.”

Pricing and Availability
XML Authority, bundled within Arbortext’s Epic Architect, is provided at no
charge to Epic Architect customers currently on maintenance and will be
included at no additional cost in future releases of Epic Architect.  All
Arbortext customers are eligible to receive this capability within Epic
Architect as part of the Epic 4.0 upgrade that will ship in July 2000.
