WHO:      Jeff Saling, Vice President of Callidus On-Demand



WHAT:     Callidus' presentation, "On-Demand: Adding it to Your Traditional

          Application Line," will highlight the steps that traditional

          software vendors must take in order to strategically implement an

          on-demand service into their suite of services. Saling will

          discuss how Callidus implemented its on-demand service into the

          company's portfolio of solutions, and will share some lessons

          learned and best practices. The presentation will also examine

          how many vendors are accommodating their customers' requests by

          essentially going "hybrid" -- offering both on-premise and

          on-demand solutions to best meet the immediate and long-term

          business needs of their customers. Saling will discuss additional

          considerations traditional software vendors should think through

          before adding an on-demand service to their suite.



          Participants of the session will learn:



          -- The financial, engineering and customer-service issues to

             consider before implementing an on-demand service into their

             traditional application line



          -- Ideas on how to avoid cannibalizing their current on-premise

             revenue by adding an on-demand service



          -- Ways to safeguard current cash flow and utilize revenue

             recognition once their on-demand service is available



          -- What is needed in terms of resources and how much they need

             to financially allocate to be successful



WHEN:     Friday, April 4, 2008

          2:15 p.m. - 2:45 p.m. PDT
