Commitment to Open Industry Standard SyncML Expands Reach of Sun's Products to Mobile Phones

Royal Tunbridge Wells, San Francisco, August 22, 2007. - Synchronica plc (AIM: SYNC.LN), international provider of industry standard mobile synchronization and device management solutions, today announced that Sun Microsystems Inc. (NASDAQ: SUNW) has agreed to license Synchronica's synchronization and client provisioning technology for Sun's communication products.

As part of the agreement, Sun plans to incorporate key components of Synchronica's Mobile Gateway for industry-standard wireless synchronization of contacts, calendars, tasks, and other enterprise data to Sun Java System Communications Suite and Sun Java System Application Platform Suite.

The Sun Java System Communications Suite is currently used by 240 million e-mailboxes within leading service providers and large organizations for messaging and collaboration services, such as email, IM and calendaring.

"We're excited to be working with Synchronica because this relationship extends Sun's reach beyond the already wide range of supported desktop clients to a large number of mobile devices", said Karen Tegan Padir, Vice President, Software Infrastructure, Sun Microsystems. "This collaboration also enables our application server developers to build feature-rich and scalable mobile applications that support both connected and disconnected operations."

Sun plans to use the core SyncML synchronization engine and the back-end connectors of the Mobile Gateway product to synchronize SyncML-enabled devices with the Sun Java System Communications Suite or Sun Java System Application Platform Suite.

Furthermore, Sun intends to use the provisioning module (OMA CP) enabling over-the-air configuration of mobile devices, reducing the need for manual device configuration. In addition, Sun is planning to use Synchronica's SyncML clients for Windows Mobile / Pocket PC and Palm OS, enabling industry-standard synchronization on smartphones that do not support SyncML out of the box.

"Open industry standards are the only way to provide secure synchronization capabilities to the widest range of smartphones and feature phones on the market today", said Carsten Brinkschulte, CEO of Synchronica. "Synchronica has long been committed to supporting industry standards such as SyncML, and today's agreement with Sun validates that open industry standards are the way of the future for technology innovation."

Commenting further on the license agreement, Carsten Brinkschulte said, "The licensing of core elements of our Mobile Gateway product to a major software infrastructure provider such as Sun represents a significant breakthrough for Synchronica. We look forward to a strong and ongoing strategic relationship with Sun."
