      modules

            support includes every necessary support for the SICAP(R) PPB, VCA
            and OTA (no accumulation of unused hours)

      o     Remote support via ISDN line (establishment and communication costs
            to be paid by customer). Security can be guaranteed under the
            following conditions: Firewall, only outgoing connections allowed

      system management, hidden modification and/or "foreign"
      developments/adaptations of the SICAP application and/or the entire
      prepaid system. Misuse will be charged at cost.

1.2   Over all responsibilities

      EuroTel is responsible for the initial fault tracing within the entire
      prepaid system including first level maintenance, Sicap Ltd for second

      have the entire prepaid system running under normal condition including
      application administration, dB administration and system administration
      (hardware & operating system).

      For second level of maintenance are intended all the activities needed to
      have the SICAP(R) application running under unexpected conditions like
      bugs, unexpected performance limitations, etc. (HW configuration and any
      changes to be confirmed by Sicap Ltd)

      problems within its own support organisation in order to achieve problem
      resolution with Sicap Ltd support.
