ISP SURVEY CONFIRMS ROCKLIFFE'S OPTIMISTIC FORECAST FOR GROWTH IN 2002

ISPs Cite E-mail and Broadband As Primary Revenue Generators

Campbell, California - June 5, 2002 - Rockliffe, Inc., the developer of e-mail and messaging infrastructure software for service providers and corporations, announced today it is optimistic about increased growth and revenues for 2002. Rockliffe's optimistic view is based on a survey of ISPs conducted recently by Surveymonkey.com.

The world wide survey including Asia and Europe indicates that 68% of all ISPs are confident about business prospects for the next 12 months. In the US, 62% echo this confidence despite the sluggish world economy.

Looking at developments within the industry, 47% of ISPs thought that they would be able to meet the expected e-mail growth rate of 138% per annum that analysts at IDC predicted. 77% of respondents from the US and UK thought that smaller ISPs would be able to survive and compete against multi-national 'super' ISPs, however, for the rest of the world this figure fell to 62%.

"With global markets as potentially volatile as they are at the moment", said John Davies, President and CEO of Rockliffe. "It is good to see that service provider confidence here in the US and in key IT markets such as Europe and Asia remains high." Davies continued, "Rockliffe's revenues increased substantially in 2001 despite the recession, and with this renewed optimism we expect even higher growth in 2002."

Globally, the survey showed that 78% of service providers believe that service level agreements and customer service are the primary selection criteria for business customers, while 77% said that consumers select based on price. Deployment of broadband, e-commerce and e-mail were seen as the three biggest drivers of Internet growth - 60% of ISPs thought that e-mail has the largest potential to generate revenues.
