included in the license are 1.7% of the sales price of Power Sourcing Equipment,

which includes wireless access points.&#160;&#160;&#160;In addition, Netgear
made a payment of $350,000 upon signing of the license agreement.</font></div>

Remote Power Patent relates to, among other things, the delivery of power over
Ethernet cables in order to remotely power network connected devices including,
among others, wireless switches, wireless access points, RFID card readers, VOIP
telephones and network cameras.&#160;&#160;In September 2003, the Institute of
Electrical and Electronic Engineers (IEEE) approved the IEEE 802.3af Power over
Ethernet standard which has led to the rapid adoption of
PoE.&#160;&#160;&#160;In September 2009, the IEEE approved the IEEE 802.3at
standard, which is an amendment to the Power over Ethernet
Standard.&#160;&#160;&#160;The IEEE 802.3at standard increases the amount of
power that can be delivered over Ethernet cables, which will allow devices with
increased power requirements to also be remotely powered.</font></div>

significant deployment savings and increased service reliability through
centralized backup power. These benefits have caused analysts to identify PoE as

offerings.</font></div>
