Plumtree Unveils 2005 State of the Portal Market Report

       Portals Among the Highest Priorities at Large Companies;
            Essential for Web-Based Application Deployments

   Plumtree Software (Nasdaq:PLUM) today announced it has completed
its annual analysis on the state of the corporate portal market. The
new report, "The Corporate Portal Market in 2005: Portals, Composite
Applications and Integrated Activity Management," reveals that CIOs at
large enterprises rank portal projects among their highest spending
priorities for 2005. It also substantiates an emerging industry
consensus that portal technology is the delivery vehicle for a new
generation of composite applications in a marketplace driven by the
promise of service-oriented architectures (SOA).
   Plumtree's report is based on information gathered from customer
and industry analyst interviews and synthesizes over 100 industry
reports published on the portal and allied markets in the past twelve
months. It offers insightful analysis into five key areas: the
evolution of the corporate portal market, market segmentation, portal
usage and functions, deployment costs and return on investment. This
original study is available for download exclusively at

   Other interesting findings in the Plumtree report include:

   --  Personalization features are declining in importance

   --  Collaboration is critical and becoming common place

   --  Applications are on the rise and the use of portal software
        for Integrated Activity Management applications is the most
        important and fastest growing trend among Plumtree customers

   --  Portals are here to stay -- 97 percent of Plumtree customers
        said their company's preference is to build new Web-based
        applications within the portal

   "As the new report illustrates, portals are taking on a new and
critical importance to enterprises as they deploy their SOA
strategies," said John Kunze, CEO at Plumtree Software. "In the
report, our customers indicate a key benefit of Plumtree's portal
solution is the ability to develop and deploy Integrated Activity
Management applications on our open framework. They understand that by
integrating user needs, IT systems and business processes via the
portal, they have taken the first steps in delivering a SOA."
