                                  SCOPE OF WORK

This proposal covers the incremental effort over and above that included in the
original Software MOU to provide Datacenter capabilities to the ISMSI solution.
The original proposal covered a simple Store Host to POD data transfer, no
provision was made for Datacenter functionality or database replication
(automatic selective). Based on the development to date and the need for the
solution to scalable beyond 25 stores it is clear this is a requirement.
