Mobile E911 Is in Crisis Location Information from mobile E911 Calls is often missing or inaccurate 70% of E911 Calls are Wireless Wireless E911 400,000 daily E911 calls from wireless devices 36% of all households have no landline (52% of families in poverty and 58% of renters) Outdoor location depends on GPS, which does not penetrate indoors in urban markets No indoor location accuracy standards exist Source: FCC, CTIA. NextNav is deploying a revolutionary positioning network to meet this need GPS-like accuracy, indoors where its needed Floor-level vertical accuracy Dedicated, mission critical network Performance validated in FCC-sanctioned trials 2012 NextNav LLC.

Communications Safety, Reliability and Interoperability Council Trials ( CSRIC ) In 4Q12 the FCC s CSRIC advisory group held a comprehensive, independent trial of location technologies for indoor E911 in the San Francisco / Silicon Valley area. Joint effort by Public Safety, technology vendors and national wireless carriers.

In-Building Requires High Performance Location and Height Across all morphologies, in the CSRIC test bed NextNav delivered 37m accuracy (population-weighted) 67% of the time and was able to identify the building or an adjacent building over 80% of the time. In the CSIRC test bed, NextNav delivered floor-level precision, with median vertical accuracy of 2 meters. 2012 NextNav LLC. All Rights Reserved. 6

Progeny FCC Testing Process 18 Months of Rigorous Testing Using Virtually Every Type of Part 15 Device 3 years of operating history in SF Bay area More than 6 months in Top- 40 US Markets Substantial Spectrum Sharing Concessions Broadcast only Eliminated licensed return path links 10-20% duty cycle Will work with rural WISPs to ensure sharing Will not collocate on towers used for utility monitoring NO Impact at all outside 4 MHz of beacon operation NO instance of overload in or out of band Minimal impact even within 4 MHz in normal operations Moderate impact even in forced cochannel and worst case collocation tests Progeny s M-LMS network shares the 902-928 MHz band with Part 15 devices in the same way Part 15 devices share with each other 2012 NextNav LLC.

In Conclusion Unlicensed devices interfere with each other constantly, but are designed to frequency hop and avoid interference when they see it Progeny uses only a small fraction (4 MHz) of spectrum and designed its network to reduce interference potential by one-way operation and 10-20% duty cycle (FCC waiver to reduce potential interference) FCC has required live field testing for 18 months and two separate public comment periods for consideration. Progeny has successfully co-existed with all manner of unlicensed equipment for over 3 years in Progeny/NextNav s Bay Area network Testing proves Progeny/NextNav s E911 location service does not cause unacceptable interference to unlicensed devices. Vast majority of unlicensed devices never even detect Progeny/NextNav operations. 11
