Rockliffe Continues Growth

Messaging Infrastructure Developer Doubles Office Space

Campbell, CA -July 25, 2003 - Rockliffe, Inc., a leading developer of messaging and email infrastructure software solutions, today announced its move to the ninth floor of the Pruneyard Towers. Rockliffe's move more then doubles the current space of the company headquarters. The need for additional space is due to Rockliffe's expanded workforce to accommodate their growing customer base. In 2002, the company hired vice presidents of customer service and marketing and increased the size of its global sales team. Rockliffe also opened an office in London to complement its existing offices in Edinburgh, Leeds, Calgary and Phoenix.

Rockliffe recently introduced MailSite NS for HP NonStop Servers, a carrier-scale messaging platform jointly developed with Hewlett-Packard. Rockliffe will also expand its global support organization and has plans to announce, in late summer, MailSite version 6 which features powerful next-generation spam filtering.

"Our employees now have significant space to work", said John Davies, president and CEO. "The last year has seen substantial growth and we simply needed more room. Our customer base is expanding and we need to keep pace. Rockliffe has always stood for "rock-solid" software, support and solutions."
