NAVINI ANSWERS CONNECTIVITY DEMAND IN AFRICA.

Navini Networks, Richardson, Texas, and its customers are addressing the need for connectivity across Africa. Navini's equipment delivers portable high-speed Internet access with plug-and-play activation and retail friendly distribution that brings personal broadband to consumers and small businesses.

There is strong momentum in Africa. Ongoing deployments include Tanzania, Ghana, Nigeria, Zambia, South Africa and Mauritius.

"There is a very clear need for broadband Internet connectivity (Personal Broadband) that can be delivered quickly and easily via wireless. It's a natural fit, given the lack of wired infrastructure," said Roger Dorf, Navini's president and CEO. "We have 11 different operators deploying today and expect to add more African countries to the list in 2007."

Africa has the opportunity to 'leapfrog' DSL / Cable / GSM and go straight to mobile WiMAX /4G networks. Navini's high-speed wireless broadband systems offer easy deployment and activation, allowing Africa to stimulate Internet growth quickly with inexpensive mass-market devices.

Some recent customer quotes...

"With high consumer demand, poor DSL access and long customer connection times, Ghana is absolutely ready for mass market, rapid install, broadband wireless services," said Leslie Tamakloe, CEO, Internet Ghana.

"Our goal is to provide broadband wireless Internet and intranet services to the principal cities of Nigeria -- Lagos, Abuja and Port Harcourt," said Munish Sharma, Managing Director of DOPC.

"Nigeria is woefully behind many other countries in terms of broadband penetration," said Ibrahim-Ali Amin, Chairman of the Board, Horizon Wireless. "We will change that by 'unwiring' and bringing wireless broadband to the population, with very attractive rates."

"For operators around the world, there are three key advantages to mobile WiMAX systems -- the open model, ease of deployment and pricing," added Dorf.

Navini's leadership in Africa follows the leadership already established in other countries and continents around the world. Navini already has the largest personal broadband deployments in the world.
