Integration of Stylus Studio and XA35 XML Accelerator Establishes a
Homogeneous Solution for the Creation, Validation and Accelerated
Deployment of Distributed XML Applications

CAMBRIDGE, Mass. and Burlington Mass.-November 13, 2002-DataPower
Technology, Inc., the leading provider of intelligent XML-aware network
infrastructure, and eXcelon Corporation (Nasdaq: EXLN) today announced
the availability of eXcelon's Stylus StudioT integrated with the
DataPower XA35 XML AcceleratorT.  The uniform solution is designed to
speed both the performance and time to market for Web Service
applications by offering a single platform for the development,
validation and deployment of high-performance XML-based applications.

eXcelon's Stylus Studio is an award-winning integrated development
platform (IDE) for creating, validating and debugging XSL stylesheets
and XML-to-XML mappings.  DataPower's XA35 XML accelerator is the first
network device purpose-built to process XML at wire speed, increasing
XML performance by 10x or better.  The XA35 offloads XML processing from
costly general-purpose servers and eliminates the need for developers to
hand optimize stylesheets or "dumb-down" applications because of
performance concerns.  Together Stylus Studio and XA35 offer enterprises
an efficient solution designed to reduce the development cycles
necessary to distribute XML applications and Web Services across the
enterprise and significantly boost application performance delivery.

"Having separate systems for the development, validation and deployment
of XML applications creates challenging productivity problems for our
customers seeking to offer robust XML-based applications," said Larry
Alston, EVP Product Management for eXcelon.  "By providing an open XML
IDE we are able to integrate seamlessly with all the major XSLT
processors on the market, including DataPower's XA35, enabling customers
to reduce the time to market and costs associated with Web Services
development cycle."

"Today, XML developers face two critical problems, the first is the
painstaking task of hand coding complex applications and the second is
application performance," said Eugene Kuznetsov, founder, president and
CTO of DataPower Technology. ""The integration of our XA35 XML
Accelerator with eXcelon's industry leading XSLT IDE offers enterprises
a powerful tool for the fast, efficient and cost-effective development
and deployment of XML applications."

Historically, XML applications have been developed separately from the
production infrastructure used to launch them across the enterprise.
Due to inconsistencies between platforms and software-based XML
accelerators, this process increases development and quality assurance
cycles, and ultimately the time necessary to get the applications to
final production. With the integration of DataPower's XML accelerator
and eXcelon's Stylus Studio IDE, enterprises can now substantially
shorten this timeline by developing and debugging 'on-the-fly' in the
same runtime environment used for deployment.

Important factors that could cause eXcelon's actual results to differ
from these forward-looking statements include unexpected delays involved
in the closing of the proposed merger between eXcelon and a wholly-owned
subsidiary of Progress Software Corporation as a result of which eXcelon

eXcelon's or Progress Software Corporation's inability to satisfy the
conditions to closing of the merger; or failure of eXcelon's
stockholders to approve the merger; the possibility that the recent
restructuring of our business operations, as well as any additional
restructuring initiatives, may not produce improvements in eXcelon's
operating results; market demand for XML-based products; the risk that
eXcelon's revenues will not grow rapidly enough to offset increased
expenditures that we are incurring to develop and market eXcelon's new
XML-based products; the risk that eXcelon's declining revenues may
adversely effect eXcelon's liquidity; the fact that a significant
portion of eXcelon's revenues to date have been derived from sales of
eXcelon's Object Design data management products, the market for which
is stable or declining; the profitability of eXcelon's professional
services contracts; eXcelon's ability to retain existing professional
services clients and attract new clients; the possibility that eXcelon
may be unable to keep pace with the rapid technological change and
intense competition that characterize its markets; general economic and
