Business and Technology Editors

PHILADELPHIA & NEW YORK--(BUSINESS WIRE)--August 21, 2000

Meeting increasing demand for wireless applications, Bluestone(R) Software, Inc. (Nasdaq: BLSW), a leader in business-to-Web and wireless technologies, and Zyglobe(R), Inc., a leading mobile software infrastructure firm, today announced Zyglobe's selection of Bluestone's Internet Operating Environment(TM) as the B2B (business-to-business) foundation for its forthcoming Zy-MobileServer product offering.

The integrated Zyglobe/Bluestone framework, slated for availability this September, will provide virtually all of the components that financial service firms, such as banking, brokerage, and insurance businesses, need to enable their mobile infrastructure. With wireless-enabled applications, consumers and business professionals can conduct business over the Web using effectively any smartphone, personal digital assistant (PDA), paging device, handheld computer, or set-top box. While Zyglobe will initially focus on bringing its mobile server infrastructure to financial institutions, its future plans include targeting additional vertical markets, such as sales force automation and public utilities.

Specifically, Bluestone's comprehensive, J2EE- and XML-based Total-e-Business(TM) platform will ensure that Zyglobe can deliver unmatched performance, large environment robustness, fault tolerance, rock-solid security, and heightened scalability. Zyglobe products will allow businesses to provide immediate access to Internet-based information through mobile devices, such as mobile phones, interactive pagers, and Personal Digital Assistants (PDAs) using Wireless Application Protocol (WAP) or any other protocol, as well as via the Web.

Using Bluestone's technology, based on Sun Microsystems' J2EE (Java 2 Platform, Enterprise Edition), Zy-MobileServer will be able to automatically detect the protocol and device-specific request, and generate the relevant protocol and content--PQA for Palm computers, WML/HDML for WAP-compatible devices, compact HTML for I-Mode, PocketPCs, Psion devices, Short Messaging Service for SMS compatible phones, pagers, etc. Ultimately, it delivers fast and reliable mobile access to a company's Internet operations, including B2C (business-to-consumer) and B2B e-commerce. Zyglobe uses Bluestone's proven support for XML-based, enterprise data integration to fit seamlessly into virtually any customer's technology environment, regardless of its operating systems, legacy operations, CRM (Customer Relationship Management) system, ERP (Enterprise Resource Planning) system, databases, or Web or application servers.

"Bluestone offers a proven foundation for wireless-enabled applications, with unmatched adherence to industry standards," said Sudarshan Venkatraman, CEO of Zyglobe. "By combining our expertise in the wireless arena with Bluestone's, we will be delivering an end-to-end framework for wireless applications that will provide connectivity between literally any front-end device and any data source. Bluestone offers both a technically superior infrastructure for wireless applications, as well as a strong commitment to our success."

Added John H. Capobianco, executive vice president of strategic planning for Bluestone Software, "The next wave of e-business applications are those that allow end-users to interact with the Web using any Internet-enabled device. For these next-generation applications to work easily and consistently, a new software layer is required that combines an Application Server and Integration Server with required e-commerce services. Bluestone integrates all of these necessary components into a robust Internet Operating Environment that provides unprecedented scalability, fault tolerance, failover, and inter-application integration. For ISVs seeking rapid entry into the explosive marketplace for wireless applications, Bluestone provides a comprehensive, proven foundation."
