2. COMPANY CONFIDENTIAL Nethercomm Background Nethercomm is a privately-held Delaware corporation based in Southern California and led by start-up veterans who have extensive experience in developing and rolling-out new communications technologies. Nethercomm plans to deliver the industrys most capable and lowest cost last-mile communication technology by combining our intellectual property and proprietary technologies with established broadband and natural gas distribution systems..

3. COMPANY CONFIDENTIAL The market for broadband services is enormous 47 Million US Broadband Subscribers 47 Million US Broadband Subscribers 95 Million Domestic Cable/Satellite TV Customers 95 Million Domestic Cable/Satellite TV Customers 112 Million Residential Telephone Lines in the US 112 Million Residential Telephone Lines in the US Broadband Internet Subscriptions grew over 37% last year Broadband Internet Subscriptions grew over 37% last year 20 Million US Homes used Video-on-Demand in 2004 20 Million US Homes used Video-on-Demand in 2004 Last year 32 Million residences received telephone service from non-RBOCs Last year 32 Million residences received telephone service from non-RBOCs Adoption of broadband services remains constrained Today D/L rates average <3 Mbps; by 2009, 57-84 Mbps will be needed Today D/L rates average <3 Mbps; by 2009, 57-84 Mbps will be needed U.S. pays about $35/month for 1.5Mbps; in Japan, about $25 for 26 Mbps U.S. pays about $35/month for 1.5Mbps; in Japan, about $25 for 26 Mbps 80% do not have broadband, including half of those earning over $75K 80% do not have broadband, including half of those earning over $75K The residential Broadband Industry will be worth $90B by 2009 representing a seven fold increase in revenue over the next five years. -- ARC Group (www.arcgroup.com) Broadband Background.

4. COMPANY CONFIDENTIAL Nethercomms Intellectual Property Enables Delivery of Broadband Services Over Natural Gas Distribution Piping Nethercomms proprietary system "piggybacks" high-performance broadband communications over existing natural gas distribution networks Broadband-in-Gas (BiG) leverages existing natural gas infrastructure to bridge the last mile which hampers other broadband approaches. Nethercomm invented the BiG technology and is developing and making BiG available through our development partners and strategic alliances..

5. COMPANY CONFIDENTIAL Nethercomm Wireless Transmission: --Uses wireless radio frequency (RF) transmission like a conventional radio station broadcasting through the atmosphere --Signal travels through the hollow center of existing Natural Gas distribution pipes like a coaxial cable, with the gas being the conductive wire Broadband in Gas (BiG) Network Technology Harnesses Basic Physics For Super-Efficient Signal Transmission Using signals inside a buried conduit presents an unlimited private spectrum -very low-noise within the operating environment, zero conflict with external applications.

6. COMPANY CONFIDENTIAL Ultra Wide Band (UWB) Communication: Extremely low-power transmission -- tiny fractions of a watt for safe, efficient transmission in flammable environment Spreads signal over a block of frequencies -- opposite of conventional radio, which puts high power into a narrow frequency band Wide-spectrum signal inherently robust, recoverable, and interference-resistant -- UWB redundancy keeps signal intact even if an external source jams a frequency Widely used for state-of-the-art commercial wireless and military communications -- high efficiency, high reliability, high performance Ultra Wide Band (UWB) is a Communication Technology Declassified by the US Defense Department in 1994 Emitted Signal Power Narrowband Communications (30KHz bandwidth) Spread Spectrum Communications (5MHz bandwidth ) Ultra Wideband Communications (Several GHz bandwidth).

7. COMPANY CONFIDENTIAL Nethercomms Advanced Encoding Techniques Use Digital Signal Processing to Enhance System Performance Multiple layers of security including full encryption and hardware authentication -- intrinsic data integrity checks, strong barriers to theft of data or services Automatic traffic compression for increased throughput -- maximize productivity of available bandwidth Digital keying" allows multiple streams to share the same frequency range -- can reuse same spectrum without conflict for multiple independent signals Intelligent protocol for robust network operation and quality-of-service management -- provides support for advanced applications such as partitioned VoIP bandwidth.
