ZixIt Announces Adoption of ZixMail by ObjectSpace, Inc.; ZixMail Encryption and Compression Technology Enables Secure Communication

DALLAS--(BUSINESS WIRE)--March 30, 2000--ZixIt Corporation (Nasdaq:ZIXI) today announced that Dallas-based ObjectSpace, Inc., a premier provider of business-to-business integration products and services, has selected ZixMail(TM), ZixIt's secure document delivery, private email, and message tracking service.

ZixMail is based on ZixIt Corporation's Digital Signature and encryption technology.

ObjectSpace, Inc. will use ZixMail, with its advanced encryption and compression capabilities, to link its consultants to its client companies. ZixMail not only encrypts, but automatically compresses any number of attachments, whether one file or one hundred. Working in teams to customize its business-to-business products for each customer, ObjectSpace, Inc. and its consultants need to be able to exchange information, much of it proprietary, quickly and securely with companies around the world. ZixMail's Worldwide Signature server, a centralized real-time public key management system that can store and distribute public keys for every email address in the world, and ZixMail's ability to establish irrefutable digital identities for both the sender and recipient are especially important for email sent from outside locations and for business-to-business e-commerce.

"The successful implementation of our OpenBusiness(TM) business-to-business integration solutions hinges upon our ability to respond to our customers' needs instantly and with the confidence that all communications are both secure and reliable," said David Norris, president and chief executive officer of ObjectSpace, Inc. "With ZixMail, we are able to communicate so quickly and seamlessly with our clients that we have the competitive advantage of seeming like we are right down the hall -- even if we are actually in different countries."

David P. Cook, chairman and chief executive officer of ZixIt Corporation, commented, "We welcome ObjectSpace to the growing list of ZixMail users. We are particularly excited that a company of their stature in the hi-tech community is adopting ZixMail."

With headquarters in Dallas, ObjectSpace is the premier provider of business-to-business integration products and services. The company's new OpenBusiness solutions are the "universal business connectors" that help companies sustain and enhance competitive advantage. OpenBusiness solutions, in combination with ObjectSpace's industry-recognized consulting and training services, allow companies to create new revenue opportunities and increase efficiencies.
