SAN ANTONIO, May 31, 2007 (BUSINESS WIRE) -- Nighthawk Systems, Inc.
(OTCBB:NIHK), a leading provider of intelligent wireless power management and
emergency notification solutions, announced today that it has received the
largest initial order in Company history for CEO700 whole house disconnect units
from the Town of Smyrna, Delaware. Smyrna has ordered 300 units in order to
decrease the time and expense associated with frequent connects and disconnects
at transient housing locations such as apartments. The sale was made with the
assistance of Rumsey Electric, one of the nation's leading electrical
wholesalers.

The CEO700 gives electric utilities the ability to remotely connect and
disconnect power to residential electric meters on a moment's notice, improving
customer service response times and saving the utilities significant time and
money compared to the traditional manual method that requires truck rolls and
field personnel.

H. Douglas Saathoff, Nighthawk's Chief Executive Officer, commented, "I'm
extremely pleased to receive this order from the Smyrna. Smyrna is a
forward-thinking municipal utility and exemplifies the changing regulatory
environment in the electric utility sector. In an effort to both increase
customer service response times and decrease costs associated with power
connects and disconnects, the city is enacting regulations requiring developers
of multi-tenant facilities to install remote connect/disconnect units on new
facilities. I'm also very pleased with the continued growth of our
distributor/reseller network, which has begun to pay dividends in the form of
new and more frequent sales of our products."
