WIND — a Leading Italian Operator of Integrated Fixed-Mobile-Internet Communications Services — Launches New Consumer Mobile Email Service With Critical Path's Memova Mobile

Business Wire, May 8, 2006

SAN FRANCISCO & TURIN, Italy -- Critical Path, Inc. (OTC:CPTH), a leading provider of messaging software and services, today announced that Wind Telecomunicazioni SpA (WIND), Italy's leading operator of integrated fixed-mobile-Internet communications services, has deployed Memova(R) Mobile -- Critical Path's push mobile email solution for consumers. Wind is using Memova Mobile to launch a new service called MMSMail, which enables subscribers to easily send and receive mobile email on a broad range of popular consumer mobile phones.

Wind chose Memova Mobile based on the solution's ability to boost MMS traffic and address the needs of the mass market. Memova Mobile works on any standard MMS-enabled mobile phone and gives subscribers easy access to their existing email accounts. For example, Wind's Libero email users, as well as subscribers who use any other standards-based email service, can use the MMSMail service to send and receive email from their everyday mobile phones. The service also allows users to choose which email messages they receive, providing on-the-go access to the messages that matter most, while preventing unwanted messages and mobile spam.

Memova Mobile offers a number of consumer-oriented features designed to help operators drive mass-market adoption. For example, unlike other mobile email services that require proprietary devices or smart phones, most subscribers do not need to upgrade their phone to use the service. Additionally, Memova Mobile requires no software download or installation, so set-up takes seconds. The Memova-powered service also supports multimedia email attachments and offers flexible reply options, including voice reply where users can respond to emails by recording a voice clip that is then emailed as an attachment.

"Wind's deployment of Memova Mobile is another great example of how service providers are taking advantage of the growing popularity of mobile email, while recognizing that it takes new, more consumer-friendly solutions to go after the mass market," said Donald Dew, CTO, Critical Path. "Affordability, ease of use and the ability to personalize and control the email experience are all features that Memova Mobile provides and that, we believe, are critical to success with consumers. We're pleased to work with WIND to bring these new capabilities and mobile email services to market."

Wind's soft launch of the new MMSMail service (http://www.wind.it/it/privati/servizi/wind_privati_servizio3021.php) began Friday, April 21, 2006.
