To e ror efS t aor Band Selection and Channel Assignment * for Base Stations TerreStar Vendors can progress only so far with their R & D without final band selection = Blocks Selection —Which combination of the S—band blocks will TerreStar be assigned? @ A and C, B and D, A and D or B and C x Transmit and Receive Spacing — What will the spacing be? — Base Station impact « Designs have already progressed significantly beyond the "from scratch" phase « The development timeline is already pressed to meet the required system deployment date, any changes to the current design (channel spacing) will cause extra challenges in meeting the timeline. «_ The later the decisions are made, the greater the impact. « Changes to the current assumptions will further delay the timelines Proprietary and Confidential — Use or distribution subject to restrictions on first page

Handset Development Timelines — Industry Historical Perspective NOE T w O R K § + A typical time frame to development handset is between 11 and 19 months — First of its kind products can take 24 to 30 months (i.e. Apple iPhone, Motorola Razor) «_ Development of some hardware components and chipsets has a dependency on the actual frequencies used — A delay in knowing the frequencies will very probably push out all delivery milestones Proprietary and Confidential — Use or distribution subject to restrictions on first page

Why such a long development time? Te rof S t a r Think Mobility from a handset perspective «_ Increasingly complex handset features and data services require more sophisticated software «_ ~85% of workload in 3/4G handsets is in software design +« Software design is heavily impacted by chipset Chipset is impacted by frequencies used 1 ATC 2 2 2 No coverage 1 1 Satellite 3 Satellite 2 2 4 ATC + SAT 4 8 5 GSM 2 2 6 lATC+GsMm 4 3 7 ATC + SAT + GSM 8 384 s |sAT+GsM 4 8 9 WiFi 2 2.

TerreStar Band Selection and Microwave Market Clearing *"***~ loeltealis L —« TerreStar cannot properly plan or begin incumbent microwave clearing in support of satellite initial operation without band selection « Use of 10 MHz downlink for satellite depends on actual frequencies used « TerreStar is delayed in microwave clearing for ATC deployment « Clearing process is 10—13 month process and must be cleared prior to ATCisatellite operations « Financial risk of TerreStar launching satellite and not being able to radiate due to delay in microwave clearing driven by delayed band selection @ Significant financial impact « For example, TerreStar analysis shows that for Miami market there are 34 interfered paths in A/B bands and 18 interfered paths in C/D. Early clearing activity that is subsequently reversed by band selection would be of significant financial impact to TerreStar Proprietary and Confidential — Use or distribution subject to restrictions on first page
