Z L - The undersignedzrtif=i seven Telstar 5 transponders have been coordinated with the adjacent satellite operators, within +/- 6", to operate with a saturated wideband digital carrier occupying 27 MHz bandwidth, with maximum satellite EIRP density of +12 dBWI4 kHz at beam center. The seven Telstar 5 transponder numbers and the corresponding up and downlink frequencies at the centers of the digital carriers are as follows: Center frequencies (MHz) of Telstar 5 the +12 dBW/4 kHz transponder number Upldownlinks 2 14021.5 111721.5 2 14035.0 1 11735.0 2 14048.5 / 11748.5 4 14082.5 / 11782.5 4 14096.0 1 11796.0 4 14109.5 1 11809.5 6 14142.5 / 11842.5 13 14260.0 / 11960.0 14 14266.5 / 11966.5 18 14328.5 / 12028.5 20 14359.5 1 120.595 Transponders 6, 13, 14, 18, and 20 have 27 MHz bandwidth, same as that of the wideband digital carrier. Transponders 2 and 4 have a bandwidth of 54 MHz. Three options are shown in each of these two transponders, which correspond to placing a wideband digital carrier in the left half, center, and the right half of the transponder. Any Skynet is a registered trademark o f Loral SpaceCom Corporation

wideband digital carrier in the transponder will be operated in back-off mode to keep the maximum EIRP density at +12 dBW/4KHz at beam center. The adjacent satellite operators with whom coordination has been completed are: PanAmSat - Galaxy XI (91" W), Galaxy IIIR (95" W), and Galaxy IVR (99" W) SES Arnericom - AMC-4 (10 1" W), AMC- 1 (1 03" W) In addition, coordination with Telstar 6 (93" W) has been completed. In the future, Loral Skynet will ensure that the continued operation of these wideband digital carriers is coordinated with the satellites at 2 , 4 , and 6-degree spacings. Sincerely, A- I _-. - -- - Acceptance by SES-Amertco*:- SES-Americom agrees that coordination between Telstar 5 at 97 degrees WL operating the wideband digital carriers described in this letter, and AMC-4 (101" W), and AMC-1 (103"W) has been completed. e Londono # rector, Satellite Market Development SES-Americom 4, Research Way Princton, NJ 08540
