Customer Interaction Tracking® (CIT).  CIT is an add-on module offered with ACSR® that provides enhanced methods for tracking the interaction with Customer’s Connected Subscriber base.  The interaction may be manually initiated by a CSR or automatically generated by the Customer Care and Billing System (e.g., Past Due letter sent, Statement generated, Non-Pay Disconnect generated, etc.).  CSRs have the ability to use CIT to enter notes, log information, and schedule follow-up actions.  Together, these components enable Customer to maintain a complete history of interactions and account activities with its Subscribers, both internally and externally.  CIT additionally provides note taking functionality as well as an interaction history feature that allows specific actions to be recorded in a transaction history log and allows for scheduling of Subscriber call backs and assignment capabilities.  The call backs can be reviewed by management as well as moved among CSRs.

THIS AMENDMENT is executed as of the day and year last signed below (the “Effective Date").
