Exhibit For SES Americom, LLC Woodbine, Maryland GD Satcom 9 Meter Earth Station Compliance with FCC Report & Order (FCC 96-377) for the 13.75 - 14.0 GHz Band Analysis and Calculations 1. Background This Exhibit is presented to demonstrate the extent to which the SES Americom, LLC satellite earth station in Woodbine, Maryland is in compliance with FCC REPORT & ORDER 96-377. The potential interference from the earth station to US Navy shipboard radiolocation operations (RADAR) and the NASA space research activities in the 13.75 - 14.0 GHz Band is addressed in this exhibit. The parameters for the earth station are: Table 1. Earth Station Characteristics • Coordinates (NAD83): 39° 22’ 36.5” N, 77° 04’ 49.4” W • Satellite Location for Earth Station: (12° W) and (142° W) • Frequency Band: 13.75-14.0 GHz for uplink • Polarizations: H,V • Emissions: N0N, 648KG7W, 6M00G7W, 10M0G7W, 20M0G7W, 50M2G7W, 72M0G7W, 152MG7W, 240MG7W • Modulation: Digital • Maximum Aggregate Uplink EIRP: 45.9 dBW for the N0N Carrier 68.0 dBW for the 648 kHz Carriers 71.0 dBW for the 6 MHz Carriers 73.2 dBW for the 10 MHz Carriers 82.9 dBW for the 20 MHz Carriers 85.0 dBW for the 50.2 MHz Carriers 85.0 dBW for the 72 MHz Carriers 85.0 dBW for the 152 MHz Carriers 85.0 dBW for the 240 MHz Carriers • Transmit Antenna Characteristics Antenna Size: 9.0 meters in Diameter Antenna Type/Model: GD Satcom Gain: 59.9 dBi • RF power into Antenna Flange: No Modulation (N0N) -14.0 dBW or -14.0 dBW/4 kHz (Maximum)

• RF power into Antenna Flange 648 kHz (Continued) 8.1 dBW or -14.0 dBW/4 kHz 6 MHz 11.1 dBW or -20.7 dBW/4 kHz (Maximum) 10 MHz 13.3 dBW or -20.7 dBW/4 kHz (Maximum) 20 MHz 23.0 dBW or -14.0 dBW/4 kHz (Maximum) 50.2 MHz 25.1 dBW or -15.9 dBW/4 kHz (Maximum) 72 MHz 25.1 dBW or -17.5 dBW/4 kHz (Maximum) 152 MHz 25.1 dBW or –20.7 dBW/4 kHz (Maximum) 240 MHz 25.1 dBW or –22.7 dBW/4 kHz (Maximum) • Minimum Elevation Angle: Woodbine, Md 10.5° @ 106.4° Az. and 10.6° @ 253.5° Az • Side Lobe Antenna Gain: 32 - 25*log(θ) Because the above uplink spectrum is shared with the Federal Government, coordination in this band requires resolution data pertaining to potential interference between the earth station and both Navy Department and NASA systems. Potential interference from the earth station could impact with the Navy and/or NASA systems in two areas. These areas are noted in FCC Report and Order 96-377 dated September 1996, and consist of (1) Radiolocation and radio navigation, (2) Data Relay Satellites.

Summary of Coordination Issues: 1) Potential Impact to Government Radiolocation (Shipboard Radar) 2) Potential Impact to NASA Data Relay Satellite Systems (TDRSS) 2. Potential Impact to Government Radiolocation (Shipboard Radar) Radiolocation operations (RADAR) may occur anywhere in the 13.4 - 14 GHz frequency band aboard ocean going United States Navy ships. The Federal Communication Commission (FCC) order 96-377 allocates the top 250 MHz of this 600 MHz band to the Fixed Satellite Service (FSS) on a co-primary basis with the radiolocation operations and provides for an interference protection level of -167 dBW/m2/4 kHz. The closest distance to the shoreline from the Woodbine earth station is approximately 65.9 km Southeast toward the Chesapeake Bay. The calculation of the power spectral density at this distance is given by: N0N 648 kHz 6 MHz 10 MHz 20 MHz 50.2MHz 72MHz 152MHz 240MHz Clear Sky EIRP (dBW): 45.9 68.0 71.0 73.2 82.9 85.0 85.0 85.0 85.0 Carrier Bandwidth: CW 648 kHz 6 MHz 10 MHz 20 MHz 50.2 MHz 72 MHz 152 MHz 240 MHz PD at antenna Input: -14.0 -14.0 -20.7 -20.7 -14.0 -15.9 -17.5 -20.7 -22.7 (dBW/4 kHz) Transmit Antenna Gain: 59.9 dBi Antenna Gain Horizon: FCC Reference Pattern Antenna Elevation Angle: 10.5° The proposed earth station will radiate interference toward the Chesapeake Bay according to its off-axis side-lobe performance. A conservative analysis, using FCC standard reference pattern, results in off-axis antenna gains of -10.0 dBi toward the Chesapeake Bay. The signal density at the shoreline, through free space is: N0N Carriers (CW Carrier) PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -14.0 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -131.3 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -194.3 dBW/m2/4 kHz

648 kHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -14.0 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -131.3 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -194.3 dBW/m2/4 kHz 6 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -20.7 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -138.0 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -201.0 dBW/m2/4 kHz 10 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -20.7 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -138.0 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -201.0 dBW/m2/4 kHz 20 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -14.0 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -131.4 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -194.4 dBW/m2/4 kHz 50.2 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -15.9 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -133.3 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -196.3 dBW/m2/4 kHz 72 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -17.5 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -134.9 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -197.9 dBW/m2/4 kHz

152 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -20.7 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -138.0 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -201.0 dBW/m2/4 kHz 240 MHz Carriers PFD = Antenna Feed Power density (dBW/4 kHz) + Antenna Off-Axis Gain (dBi) – Spread Loss (dBw-m2). = -22.7 dBw/4 kHz + (-10.0) dBi – 10*log[4Π*(65900m)2] = -140.1 dBW/m2/4 kHz + Additional Path Losses (~63.0 dB) = -203.1 dBW/m2/4 kHz Our calculations identified additional path losses of approximately 63.0 dB including absorption loss and earth diffraction loss for the actual path profiles from the earth station to the nearest shoreline. The worst case calculated PFD including additional path losses to the closest shoreline location is –194.3 dBW/m2/4 kHz for all carriers. This meets the –167 dBW/m2/4 kHz interference criteria of R&O 96-377. Therefore, there should be no interference to the US Navy RADAR from the Woodbine earth station due to the distance and the terrain blockage between the site and the shore. 3. Potential Impact to NASA’s Data Relay Satellite System (TDRSS) The geographic location of the SES Americom earth station in Woodbine, Maryland is outside the 390 km radius coordination contour surrounding NASA’s White Sands, New Mexico ground station complex. Therefore, the TDRSS space-to-earth link will not be impacted by the SES Americom earth station in Woodbine, Maryland. The TDRSS space-to-space link in the 13.772 to 13.778 GHz band is assumed to be protected if an earth station produces an EIRP less than 71 dBW/6 MHz in this band. The 9 meter earth station antenna will have an EIRP less than 71 dBW/6 MHz for carriers, CW, 648 kHz, 6 MHz, 152 MHz and 240 MHz carriers in this band. The total EIRP for the CW Carrier is 45.9 dBW and the equivalent EIRP per 6 MHz segment will remain at 45.9 dBW/6 MHz. The total EIRP for the 648 kHz, carriers is 68.0 dBW. The equivalent EIRP per 6 MHz segment will be 67.9 dBW/6 MHz. The total EIRP for the 6 MHz, carriers is 71.0 dBW. The equivalent EIRP per 6 MHz segment will be 70.0 dBW/6 MHz. The total EIRP for the 10 MHz, carriers is 73.2 dBW. The equivalent EIRP per 6 MHz segment will be 71.5 dBW/6 MHz. The total EIRP for the 20 MHz, carriers is 82.9 dBW. The equivalent EIRP per 6 MHz segment will be 79.6 dBW/6 MHz. The total EIRP for the 50.2 MHz, carriers is 85.0 dBW. The equivalent EIRP per 6 MHz segment will be 76.6 dBW/6 MHz. The total EIRP for the 72 MHz, carriers is 85.0 dBW. The equivalent EIRP per 6 MHz segment will be 73.0 dBW/6 MHz. The total EIRP for the 152 MHz, carriers is 85.0 dBW. The equivalent EIRP per 6 MHz segment will be 59.7 dBW/6 MHz. The total EIRP for the

240 MHz, carriers is 85.0 dBW. The equivalent EIRP per 6 MHz segment will be 45.0 dBW/6 MHz. Therefore, there should not be interference to the TDRSS space-to-space link for the CW carriers, 648 kHz, 6 MHz, 152 MHz and 240 MHz carriers. For the 10 MHz, 20 MHz, 50.2 MHz and 72 MHz carriers, the total EIRP per 6 MHz will exceed the 71.0 dBW/6 MHz level. To avoid interference to the TDRSS space-to-space link the 10 MHz, 20 MHz, 50.2 MHz and 72 MHz carriers will not be used for the transmit spectrum of 13.772 to 13.778 GHz by this earth station. 4. Coordination Issue Result Summary and Conclusions The results of the analysis and calculations performed in this exhibit indicate that compatible operation between the earth station at the Woodbine facility and the US Navy and NASA systems space-to-earth link are possible for all of the proposed carriers. Operations in NASA systems space-to-space link (13772.0 to 13778.0 MHz) will also be permitted for all of the carriers with the exception of the 36 MHz and 54 MHz emissions.

The losses were found to be sufficient to reduce the signal levels to acceptable magnitudes in every case. Radar Characteristics 10/24/2017 Page 21 of 30
