2 Designing the Intelligent Energy Gateway 2009 CONFIDENTIAL

 Connectivity to multiple external cellular communication protocols  GSM/GPRS/CDMA/WiMax  Direct communication of pricing information to the gateway. Gateway initiates the demand response functions.  Ensure continuity between the home network and in home connected devices using various communication standards and the external world based on inexpensive cellular based two-way communication. Use Dual factor communication.  Encrypted securitized data transmission  Connectivity to a limited number of HAN communication protocols including Zigbee/HomePlug/hardwired options  Control ALL Home automation functions receiving external communication from public authorities  Security (e.g. Amber Alerts)/Public Alerts/Weather warnings  Energy  Medical  Allow connectivity to all existing home automation protocols including security systems/home area networks  Always connected to external data and internal management control  Non intrusive to the end user. 3 standardized operability

CONFIDENTIAL  Customer remote access via subscription to both push (e.g. PDA) and Pull (e.g. cellular portal)  Enable and empower end user to receive data and manage functions based on information received remotely in real time or a schedule.  Offers automated conservation modes/schedules.  Compatibility with inexpensive fixed income automated conservation devices with HAN environment.  Backward compatibility to all Thermostats and AMI systems.  Conversion of existing thermostats to smart thermostat status via wireless relay interface communicating to the gateway.  Allow for utility initiated automatic load management based on pre- defined profiles. 4 standardized functionality

CONFIDENTIAL  Standardized In home accessibility using:  Cell or smartphone  In Home full-function display  Television  Personal computer  Plug and Play connectivity or very limited requirement for professional installation.  Communicates energy savings to end user.  Remote maintenance/operation of deployed devices/data via appropriate head end system(s)  Expandable ports for additional functionality (wired or wireless)  Scalability of gateway solution to allow other industries (health, security, etc..) to offer services and products to offset cost to utility and end user. 5 standardized functionality
