Sun and Bowstreet join forces to deliver dynamic Web services assembly on Sun ONE platform

Agreement extends alliance with powerful tool for Java and iPlanet
developers, and new e-business platform support for Bowstreet customers

PORTSMOUTH, NH and Santa Clara, Calif., January 10, 2002 - Bowstreet
(www.bowstreet.com) and Sun Microsystems, Inc., today significantly advanced
the Sun ONE services on demand initiative with an agreement to port the
Bowstreet(TM) Business Web Factory to the Sun ONE architecture, including
the iPlanet Application Server and the iPlanet Portal Server platform. The
agreement brings dynamic Web services assembly -- the ability to assemble
and customize the appropriate Web services at run-time -- to the enterprise.

As part of the agreement, Bowstreet will offer a fully integrated version of
its Web services development and assembly platform, the Business Web
Factory, for the iPlanet Application Server by the end of the first quarter
of 2002. The Business Web Factory will also provide integrated support for
the iPlanet Portal Server by the end of the first quarter of 2002. This
development work furthers the alliance Sun and Bowstreet announced in
February 2001 to encompass support of the Sun ONE product portfolio. Sun ONE
is Sun's vision, architecture, product and expertise to enable the
development and delivery of services on demand. Further information is
available at www.sun.com/sunone.

The integration of the Business Web Factory to the Sun ONE portfolio
represents an important, new tool for Java and iPlanet developers who want
to create and deploy applications that leverage the scalability, high
availability and high performance capabilities of the iPlanet Application
Server. Additionally, the Business Web Factory for the iPlanet Portal Server
will enable enterprises to assemble, manage and deploy services on demand to
a broad range of clients and devices throughout the network of employees,
partners or customers. The ability to dynamically assemble content and
services into unique portal instances is expected to enable Sun ONE
customers to speed time to market and reduce maintenance costs over the
lifespan of Web applications.

"Because of the central role that application servers play in Web services
delivery, it's becoming increasingly evident that the ability to dynamically
assemble Web services is a key component for any J2EE(TM) application server
environment," said Daryl Plummer, vice president and research group
director, Gartner, Inc.

Today's announcement substantiates Bowstreet's and Sun's commitment to
integrate technologies. "Bowstreet shares our vision for a services on
demand architecture, and provides the dynamic Web services assembly our
customers will need as they develop and implement Web services," said Sun
Microsystems, Inc. Senior Director, Sun Developer Network, Shahram
Moradpour. "The combination of Bowstreet and iPlanet technologies gives our
customers the ability to assemble and customize Web services for the
enterprise."

The announcement is also a victory for developers. "Bowstreet technology
gives our developers a truly unique tool," said Director of Technology
Evangelism for Sun Microsystems, Inc., Matt Thompson. "The Bowstreet
Business Web Factory compounds the value of any tool by combining software
components from other sources and delivering them as needed to virtually any
individual or device."

"iPlanet and Bowstreet are a natural fit. Sun was first to deliver a
complete vision for platform-neutral software, and we were first to
recognize the importance of Web services and act on it commercially," said
Bowstreet Vice President of Marketing, Dave Rosenlund. "The combination of
Bowstreet, iPlanet and the Sun ONE vision lowers the cost of doing business
on the Internet."
