EAI Leader TSI Software Acquires Web Application Integration Pioneer Novera

Thursday, September 30, 1999 04:04 PM

WILTON, Conn. and BOSTON--(BUSINESS WIRE)--Sept. 30, 1999--

TSI Software Gains First-Mover Advantage in Delivering
B2B, C2B, EAI, and EDI Integration from Single Product Suite

     TSI International Software Ltd. (NASDAQ: TSFW), a leader in enterprise
application integration (EAI), today announced it will acquire Novera Software,
Inc., the pioneer in Web application integration (WAI).

     This acquisition gives TSI Software first-mover advantage in delivering a
single suite of powerful eBusiness integration software, not currently available
in the market. The combination of TSI Software's market-leading Mercator(R)
integration software with Novera's technology delivers the full range of
capabilities essential for end-to-end integration of Web applications, back-
office systems and external business partners.

     Privately held, venture-backed Novera Software, Inc. is the first company
to deliver software for seamless integration of core business systems and
databases with Web-based consumer-to-business (C2B) applications, such as
customer self-service, customer relationship management, and online retailing.
Novera's world class technology Web integration technology has been embraced by
more than 30 industry leaders in eBusiness, including Eddie Bauer, The Home
Depot, MCI, Morgan Stanley and Z-Tel.

     TSI Software is acquiring all of the capital stock of Novera for
approximately 1.8 million shares of TSI Software common stock. In connection
with the transaction, TSI Software will assume all outstanding Novera stock
options in exchange for a maximum of approximately 350,000 shares of TSI
Software common stock. The acquisition will be accounted for as a purchase
transaction and is expected to qualify as a tax-free reorganization. The
transaction is structured for immediate closing.

     "Today, every enterprise is faced with the enormous challenge of becoming
an eBusiness, almost overnight," stated Connie Galley, TSI Software's president
and CEO. "Huge investments have been made over the last 30 years in applications
and IT infrastructure that now have to be integrated with the Web. With this
acquisition, the days of companies buying or building separate B2B, C2B and EAI
products to facilitate eBusiness initiatives are over. Now companies can, for
the first time, implement a single eBusiness integration software product from a
single vendor to do it all.

     "Web-based eBusiness integration has added a major new accelerator to the
already rapidly growing EAI market, a market that has driven TSI Software's over
100% growth. Novera brings rich software capabilities, including industrial
strength management of Web-based transactions, integration with leading
application server products, and built in support for industry standards such as
Java and XML. Combined with their team of highly experienced Web developers and
marketers, these capabilities will dramatically speed our expansion into Web-
based integration."

     The strength of TSI Software's base of over 1,000 enterprise customers, its
experienced sales force and large third-party channel of over 100 resellers
should enable the rapid deployment of the combined TSI/Novera products. TSI
Software has over 550 employees in the US, Europe and Asia, and offers products
addressing the mission-critical needs of customers across all industries. These
customers include ABN Amro, American Express, Applied Materials, Bell Canada,
Citibank, Credit Suisse, Deutsche Bank, Eli Lilly, General Motors, Hershey
Foods, Hoechst, IBM, Lockheed Martin, Lucent Technologies, Salomon Smith Barney
and Texas Instruments.

     "Together TSI Software and Novera become the clear industry leader in the
eBusiness integration marketplace," said Dave Power, president and CEO of Novera
Software. "This is an exciting growth path for our business. It brings greater
market recognition, broader channel reach, and the opportunity to deliver the
industry's most comprehensive integration solution."

     According to an article by John Hagerty in the AMR Research SAP Advisory
Alert published September 30, 1999, "Novera can take any type of data and create
a standards-based object and present it in a recognizable format, such as
Extensible Markup Language (XML). The acquisition of Novera complements TSI's
Mercator product very well, and significantly enhances TSI's ability to
participate in Business Community Integration as part of mySAP.com."

Combining Market Leading Technologies

     TSI Software's EAI and WAI capabilities reflect the thought leadership
inherent in the underlying software of each company. Unlike other eBusiness
integration offerings, TSI Software's complete eBusiness integration
capabilities provide the most powerful and comprehensive support for IT
organizations now faced with the challenge of integrating eBusiness initiatives
in diverse computing environments.

     Novera's Web integration technology enables organizations to access data
from core business systems to create reusable business components based on
CORBA, COM and EJB. These business components can be exposed in multiple
recognizable Web formats, such as JavaBeans, Java Server Pages (JSP's), XML or
Servlets, making them easy to use and reuse in any Web application. Novera
supports connectivity with leading Web application server products, including
Allaire ColdFusion, IBM WebSphere, SilverStream and Sun NetDynamics. In
addition, Novera delivers the industry's only eBusiness management software
allowing customers to define and maintain system resources, view and control
eBusiness objects in real-

time, monitor and control clients and components, and facilitate dynamic load
