SAN FRANCISCO--(BUSINESS WIRE)--August 16, 1999--

Move Validates Critical Path's Commitment to

Provide Carrier-Class Internet Messaging Services

Critical Path, Inc. (Nasdaq:CPTH), a leading provider of business-to-business Internet messaging solutions, today announced it has employed EMC Enterprise Storage systems and software to increase the reliability and scalability of its global information management infrastructure.

Focused on managing its continuing growth and responding to market changes quickly and effectively, Critical Path has implemented EMC's storage solutions to ensure customers' access to business-critical information and resources worldwide.

Critical Path chose to re-build its existing infrastructure with EMC Enterprise Storage because of EMC's market leading storage solutions and its award-winning customer service and support. Currently, Critical Path is installing over 40TBs of EMC Enterprise Storage for higher performance and scalability. Critical Path has also implemented EMC's Symmetrix Manager for performance monitoring and management to avoid data loss or interruption of service.

"With the explosive growth of Web-based messaging and applications, it is imperative for Critical Path to ensure absolute up-time and scalability," said Joe Duncan, chief information officer of Critical Path. "EMC has built its best-in-industry reputation by providing exceptional Enterprise Storage solutions with world-class 24x7 support. By augmenting our services with their expertise, reliability, and ability to scale, we assure our customers of the carrier-class service they demand."

With the anticipated growth of the Internet, there is a need for rock-solid information infrastructure. Critical Path recognizes this need and is investing in EMC's technology to ensure that its infrastructure can scale as the company continues to build a worldwide presence. Critical Path and EMC will continue to work together to enhance Critical Path's services in areas which include disaster recovery, business continuity, data migration, and data movement capabilities.

"We needed to install an infrastructure that can help guarantee customers' access to mission-critical information all day everyday," said Duncan. "We are confident that with the addition of EMC's storage solutions, Critical Path offers one of the most robust and reliable email systems in the industry."

"Critical Path is managing more information than some large corporations," said Bob Dutkowsky, EMC's Vice President of Markets and Channels. "The effective management of these ever-growing volumes of information will require them to leap to a fully-grown, mature and stable information infrastructure in only months, where it used to take years. We are partnering with Critical Path to help them make this vertical leap by building an information-centric infrastructure on EMC Enterprise Storage."
