Title:


                                   EXHIBIT A

PROSPECTUS SUMMARY

Symbol Technologies

          Symbol Technologies is a provider of wireless and internet-based
mobile data management systems and services installed at more than 45,000
customer locations worldwide. Symbol provides its customer base with broad-based
package for support called SymbolCare. Symbol chose Service Hub to upgrade its
existing systems, particularly in the areas of parts logistics and repair, and
serve as the technology platform for delivering this service over the internet.
Symbol's application will use mService Gateway to enable its approximately 75
field representatives to log information about parts, expenses and calls made on
customers. SymbolCare over the internet, called MySymbolCare, is in the process
of being tested at six customer and partner locations. Symbol plans to implement
this application for its base of 5,500 customers and partners.  Using Service
Hub, Symbol will be able to integrate information from third-party call centers
and financial applications, as well as from the supply chain and repair center
modules of our Service Suite that Symbol previously purchased from us.  Service
Hub interfaces to Symbol's existing application, will allow these applications
to be phased out in a gradual fashion, rather than forcing an abrupt and costly
conversion.  Using Service Hub, Symbol expects to reduce the number of call
center requests, improve management of spare parts and increased field workforce
efficiency.
