Critical Path Launches New Memova Messaging Solutions for Service Providers; New Solutions Leverage Innovative Contact-Centric Approach to Provide Safe, Seamless Messaging Experience for Consumers.

SAN FRANCISCO & LAS VEGAS -- Critical Path, Inc. (OTC:CPTH), a leading provider of messaging software and services, today announced the launch of two new Memova Messaging solutions for service providers. The new "Universal Contacts" and "Digital Life" solutions leverage Critical Path's contact-centric approach to enable carriers, ISPs and other service providers to enhance both the security and usability of their consumer messaging services, create viral online communities and deliver new value-added services.

With the growing number of communications devices consumers own, combined with the increasing onslaught of spam, staying connected to friends and family, while blocking unwanted messages and content, has become a complex challenge. For parents in particular, there is an added worry as research shows that half of teens aged 13-18 often communicate through the Internet with someone they have not met in person.(1) As a result, consumers are looking for a simple and central way to manage contacts for applications across all devices and protect themselves and their families from unsolicited email messages and content.

Critical Path's contact-centric approach puts contacts -- rather than the email or messaging application -- at the center of the consumer experience. This makes messaging services easier to use, enables consumers to share content amongst their preferred community, and provides complete control over which messages they receive. Leveraging the proven Memova Messaging platform, Universal Contacts and Digital Life help service providers to not only enhance the consumer experience, but also deliver new revenue-generating, value-added services. For example:

--Universal Contacts -- With the Universal Contacts solution, consumers can create safe online communities and communicate more easily from any device or application. The user's contact list is centrally stored on the service provider's network server and can be integrated with any or all of their applications, including email, instant messaging, text messaging, VoIP, etc. The centralized contact list is also universally accessible from any device, including PCs, mobile phones and PDAs. Address books in all applications/devices are automatically synchronized whenever new contacts are added or updated. In an effort to eliminate spam and/or provide greater parental controls, integrated anti-abuse technology enables users to allow or block senders who are not in their universal contact list. Users can create closed, safe online communities by setting up "white lists" and "black lists" that control who can contact them via Internet or mobile messaging.

--Digital Life -- With the Digital Life solution, consumers can easily exchange photos, videos, music and other multimedia content with members of their online community. The multimedia content is stored on the service provider's network server and is tied to the user's universal contact list. The contact list denotes which members of the list have access to what content. Subscribers can easily publish content to their personal blogs, Web sites or RSS feeds and share it with their online community through email and other mobile messaging applications. The Digital Life solution allows service providers to grow online communities by taking advantage of the growing trends in user-generated content, while enabling consumers to reap the benefits of high-speed Internet connectivity through interaction with rich media.

"In the past when subscribers had just one device -- a PC -- and one form of Internet communication -- email -- it made sense for the email application to be at the heart of it all. Today, however, messaging services need to be centered around the people subscribers want to communicate with -- not the application," said Donald Dew, CTO, Critical Path. "Already, we're working with leading service providers in the U.S., Spain and Switzerland to implement contact-centric solutions, helping them to address important issues, such as spam and security, while providing a seamless user experience and reducing infrastructure costs."

The new Universal Contacts and Digital Life solutions build on the contact-centric approach already utilized in other Critical Path solutions. For example, Memova Mobile, a push mobile email and content solution for consumers, enables users to easily allow or block specified senders, controlling which messages and content they receive on their mobile.

Critical Path is exhibiting its Memova solutions this week at CTIA Wireless, April 5-7, in booth 203.
