EchoStar Satellite Operating Corporation Attachment - Conditions of Authorization File Nos. SAT-MOD-20051007-00198, SAT-AMD-20051118-00248, and SAT-AMD-20060724-00081 Call Sign: S2636 October 19,2006 EchoStar Satellite Operating Corporation's (Echostar) applications to modify its authorization to operate a Ka-band satellite, Echostar-1 13, at 113" W.L., File No. SAT-MOD- 2005 1007-00198, as amended by SAT-AMD-20051118-00248 and SAT-AMD-20060724-00081 are GRANTED, subject to the terms of its authorization in File No. SAT-LOA-20040803-00154, the technical specifications set forth in its applications, and the conditions set forth below.' Accordingly, EchoStar is authorized to operate telemetry, tracking, and command (TT&C) frequencies for its Ka-band satellite at 113" W.L. using 28.352 GHz and 28.598 GHz as the command frequencies, and 18.302 GHz and 18.798 GHz as the telemetry frequencies. In addition, Echostar's request for a waiver of section 25.202(g) of the Commission's rules is granted to allow EchoStar to operate TT&C launch and transfer orbit operations in the 13.752 GHz, 13.998 GHz, 1 1.452 GHz and 1 1.698 GHz frequency bands.2 We find EchoStar has demonstrated good cause for a waiver in this in~tance.~ First, as EchoStar states, there is no worldwide ground network in the Ka-band frequencies to support TT&C functions during launch and transfer orbit operations, while there is an extensive network of Ku-band frequencies. Further, EchoStar maintains that it will only use small amounts of spectrum for a very limited time during the launch and transfer orbit operations and will coordinate with other authorized users of the bands. EchoStar also states it will operate on a non-harmfbl interference basis. The International Bureau previously granted a waiver of section 25.202(g) tc EchoStar for its Ka-band satellite at 117" W.L. based on similar facts.4 The International Bureau has also previously granted the use of the 13.75-14.0 GHz frequency band for TT&C, both for launch and transfer orbit operations, and for on-station operations? We anticipate, howeve:r, that as more Ka-band satellite systems with TT&C links located withn band are authorized, the Ka-band TT&C earth station network will be sufficiently developed and thus there will be no need for operators to request waivers of section 25.202(g) for out-of-band transfer orbit TT&C operations. 1.

Echostar-1 13 in the 13.75-14.0 GHz frequency band is required to coordinate with the National Telecommunications and Information Administration's (NTIA) Interdepartment Radio Advisory Committee's (IRAC) Frequency Assignment Subcommittee.' 2. Operations of any earth station in the United States and its possessions communicating with Echostar-1 13 in the 13.75-14.0 GHz frequency band shall comply with footnotes US356 and US357 of the U.S. Table of Allocations which specify a minimum antenna diameter of 4.5 meters and a minimum equivalent isotropically radiated power (e.i.r.p.). Operations of any earth station located outside the United States and its possessions communicating with Echostar-1 13 in the 13.75-14.0 GHz frequency band shall be consistent with footnotes 5.502 and 5.503 to the International Telecommunication Union (ITU) Radio Regulations, which allow minimum antenna diameter as small as 1.2 meters for earth stations of a GSO network. 3. The 1 1.452 GHz and 11.698 GHz frequency bands in which EchoStar proposes to operate are allocated to terrestrial services and to the fixed-satellite service (FSS) on a co-primary basis.' However, under footnote NG104 of section 2.106 and footnote 2 of section 25.202(a)( 1) of our rules, FSS operations in these bands are limited to international service in order to limit the number of FSS earth stations with which the terrestrial wireless fixed- '' service would be required to coordinate. Accordingly, a U.S.-licensed, 6 Footnote US337 requires that earth stations operating in the 13.75-13.8 GHz band be coordinated through NTIA's IRAC Frequency Assignment Subcommittee to minimize interference to the forward space-to- space link of the National Aeronautics and Space Administration Tracking and Data Relay Satellite System. 47 C.F.R. 6 2.106, US337. These footnotes place certain restrictions on FSS operations in order to protect government operations in the band, including manned space flight. Footnote US356 places a restriction on a minimum antenna size of 4.5 meters for earth stations operating in the 13.75-14.0 GHz band and indicates a minimum e.i.r.p. that should be used. Footnote US357 limits earth station e.i.r.p. spectral density in the 13.77-13.78 GHz band until those geostationary space stations in the space research service for which advance publication information was received by the ITU prior to January 3 1, 1992 cease to operate in this band. 47 C.F.R. 6 2.106, Footnote US357. 8 Footnote 5.502 to the ITU Radio Regulations establishes minimum antenna diameters for earth stations of geostationary and non-geostationary satellite networks, and places certain restrictions on either the minimum equivalent isotropically radiated power (e.i.r.p.) or the power flux density (p.f.d.) levels produced by earth stations operating in the 13.75-14.0 GHz band. Footnote 5.503 limits FSS earth station e.i.r.p. spectral density in the 13.770-13.780 GHz band for earth stations in the FSS operating with geostationary- orbit space stations, until those geostationary space stations in the space research service for which advance publication information was received by the ITU prior to January 3 1, 1992 cease to operate in this band. '47 C.F.R. # 2.106 and 25.202(a)( 1). Allocation of a given frequency band to a particular service on a primary basis entitles operators to protection against harmful interference from stations of "secondary" services. Further, secondary services cannot claim protection from harmful interference caused by stations of a primary service. See 47 C.F.R. $6 2.104(d) and 2.105(c). lo47 C.F.R. 6 2.106 footnote NG104 states "[tlhe use of the bands 10.7- 11.7 GHz (space-to-Earth) and 12.75-13.25 GHz (Earth-to-space) by the fixed-satellite service in the geostationary-satellite orbit shall be limited to international systems, i.e. other than domestic systems." 47 C.F.R. 6 25.202(a)( 1) footnote 2 2

satellite may provide downlink service into the United States and its Possessions in the 10.7 -1 1.7 GHz frequency band only if the uplink originates outside of the United States and its Possessions. Therefore, if EchoStar wants to use any of these frequencies to provide domestic service, including telemetry and tracking services for a U.S.-licensed satellite, an earth station license application or modification, including a request for waiver of NG104 and footnote 2 of Section 25.202(a)(l), must be filed for the earth station(s) which will access the Echostar-1 13 satellite in this band. 4. EchoStar must file a modification to this authorization specifLing the precise orbital location for the Echostar-1 13 satellite." EchoStar must file this modification within 60 days of this grant. 5. EchoStar has 30 days from the date of this grant to decline the authorization as conditioned. Failure to respond within this period will constitute formal acceptance of the authorization as conditioned. 6. This grant is issued pursuant to 47 C.F.R. 8 0.261 of the Commission's rules on delegated authority and is effective upon adoption. Petitions for reconsideration or Applications for Review under the Commission's rules, 47 C.F.R. 1.106 and 1.115, may be filed within 30 days of the date of the public notice indicating t h s action was taken. 1 . states "[ulse of this band by geostationary satellite orbit satellite systems in the fixed-satellite service is limited to international systems, i.e. other than domestic systems." See also Assignment of Orbital Location to Space Stations in the Domestic Fixed Satellite Service and the Application of GE American Communications, Inc., Order and Authorization, 15 FCC Rcd 3385 (Int'l Bur. 1999). I1 Pursuant to 47 C.F.R. 6 25.1 14(d)(14), EchoStar submitted an application specifying its orbital debris mitigation plans for the 113" W.L. orbital location. In its application, File No. SAT-AMD-20060724- 0008 1, EchoStar states that the in-orbit Satmex-6 satellite operated by Satelites Mexicanos S.A. DE C.V. (Satmex) is the only satellite that will be operated at or close to the Echostar-1 13 satellite. EchoStar asserts that it has reached an agreement in principle, with Satmex, that each will operate their respective satellites at an off set from the nominal 113" W.L. orbital location, but failed to specify the offset. 3

Orbital Debris Mitigation Plan for the EchoStar Satellite Licensed to be Located at 113’ W.L. EchoStar Satellite Operating Corporation (“EchoStar”) has filed a request for modification of its authorization to operate a satellite at 113” W.L. (“Echostar Satellite”).’ Pursuant to Section 25.1 14(d)(14) of the Commission’s rules; the Commission’s Second Report and Order in IB Docket No. 02-54,3 the Commission’s Public Notice published on October 13, 2005, and the e-mail sent to Mr. Pantelis Michalopoulos by Ms. CurTisha Banks of the Commission on November 8, 2005, EchoStar requests that the Commission incorporate this orbital debris mitigation plan into Echostar’s pending modification request. EchoStar has not yet completed the design for the EchoStar Satellite. EchoStar has a contract in place for the construction of the satellite. Under its license, the design of the satellite is due to be completed by the Critical Design Review (“CDR’) milestone of October 8, 2006. Specifically, the Statement of Work associated with the satellite manufacturing contract includes provisions to review orbital debris mitigation as part of preliminary design review (“PDR”) and CDR, including a formal Failure Modes and Effects Criticality Analysis (“FMECA”). The information herein, therefore, is based on statements and assurances from the satellite manufacturer. I. SPACECRAFT HARDWARE DESIGN EchoStar can confirm that the satellite will not undergo any planned release of debris during its operation. Furthermore, all separation and deployment mechanisms, and any other potential source of debris will be retained by the spacecraft or launch vehicle. In conjunction with Space Systems/Loral, EchoStar has assessed and limited the probability of the satellite becoming a source of debris by collisions with small debris or meteoroids of less than one centimeter in diameter that could cause loss of control and prevent post-mission disposal. EchoStar has taken steps to limit the effects of such collisions through shielding, the placement of components, and the use of redundant systems. The EchoStar Satellite will include separate TT&C and propulsion subsystems that are necessary for end-of-life disposal. The spacecraft TT&C system, vital for orbit raising, will be extremely rugged with regard to meteoroids smaller than 1 cm, by virtue of its redundancy, shielding, separation of components and physical characteristics. Omni-directional antennas are mounted on opposite sides of the spacecraft. These antennas, each providing 1 EchoStar Satellite Operating C o p , Application for Modification of License to Select TT&C Frequencies for its Ka-band GSO Satellite at 1 13” W.L., File No. SAT-MOD-2005 1007- 00198 (filed Oct. 7,2005). * 25 C.F.R. $25.114(d)( 14). Mitigation of Orbital Debris, Second Report and Order, 19 FCC Rcd 1 1567 (2004) (“Second Report and Order”).

greater than hemispherical coverage patterns, are extremely rugged and capable of providing adequate coverage even if struck, bent or otherwise damaged by a small or medium sized particle. Either omni-directional antenna, for either command or telemetry, will be sufficient to enable orbit raising. The command receivers and decoders and telemetry encoders and transmitters will be located within a shielded area and will be totally redundant and physically separated. A single rugged thruster and shielded propellant tank provide the energy for orbit raising. Otherwise, there are no single points of failure in the system. EchoStar will continue to review these aspects of on-orbit operations with the spacecraft manufacturer and will make such adjustments and improvements as appropriate to assure that its spacecraft will not become sources of debris during operations or become derelicts in space due to a collision with a small or large object. 11. MINIMIZING ACCIDENTAL EXPLOSIONS In conjunction with Space Systems/Loral, EchoStar has assessed and will limit the probability of accidental explosions during and after completion of mission operations, The satellite manufacturer has taken steps to ensure that debris generation will not result from the conversion of energy sources on board the satellite into energy that fragments the satellite. In particular, the satellite manufacturer advises that burst tests are performed on all pressure vessels during qualification testing to demonstrate a margin of safety against burst. Bipropellant mixing is prevented by the use of valves that prevent backwards flow in propellant lines and pressurization lines. Pyrotechnics are nominally used in the mission only as part of the initial deployment process. After orbit raising to the disposal orbit, all unfired pyrotechnics will be fired as part of the final satellite decommission. All batteries and fuel tanks are monitored for pressure and temperature. Excessive battery charging or discharging is limited by a monitoring and control system which will automatically limit the possibility of fragmentation. Corrective action, if not automatically undertaken, will be immediately undertaken by the spacecraft operator to avoid destruction and fragmentation. Thruster temperatures, impulse and thrust duration are carefully monitored, and any thruster may be turned off via redundant valves. Consequently, there is no possibility of explosion during the operating mission. Space Systems/Loral also will conduct an FMECA as part of the design process. At the end of the satellite’s life, all traveling wave tube amplifier (“TWTA”s) will be outgassed, and all residual fuel will be consumed. All he1 latch valves will be placed in an “open” position, and any pressurized system will be vented. Spacecraft battery trickle charge and all automatic battery charging sequences will be disabled. 111. SAFE FLIGHT PROFILES EchoStar has reviewed the lists of FCC licensed satellite networks, as well as those that are currently under consideration by the FCC. In addition, non-USA networks for which a request for coordination has been submitted to the ITU in the vicinity of 113” W.L., have also been reviewed. For purposes of calculating potential station-keeping volume overlap, U.S. satellites have been assumed to have a maximum east-west excursion of k0.05”from their nominal location, while non-U.S. satellite networks have been assumed to have a maximum excursion of kO.1 O from their nominal location. -2-

Based on this review, there are two operational satellites within k0.2" of 113" W.L. These are the GOES 11 satellite operated by the National Oceanic & Atmospheric Administration (NOAA) at 113" W.L. and the Solidaridad 2 satellite operated by SatMex at 113" W.L. Once the launch vehicle manufacturer is selected for the EchoStar Satellite and a launch plan, launch vehicle and launch scenario are developed, EchoStar will engage in physical coordination with NOAA and SatMex, and any satellite operator that has launched a satellite at, or near, 113" W.L. EchoStar also will select one of the established launch agencies with a proven record of safe flight planning, taking care to minimize the possibilities of any collision. The launch contractor will be responsible for collision avoidance maneuvers and launch analysis of in-flight profile planning. Currently, no launches are expected to inject satellites close to 113" W.L. other than those discussed above. Prior to launch of the EchoStar Satellite, EchoStar will continue to monitor Commission and ITU resources to identify satellites that reasonably can be expected to operate at 113" W.L. +/- 0.2". IV. POST-MISSION DISPOSAL Upon mission completion, EchoStar will maneuver the EchoStar Satellite to a disposal orbit with a minimum perigee of 350 km above the normal GSO operational orbit. This proposed disposal orbit altitude is well above the IADC formula, as required in 47 C.F.R. 325.283 and the Commission's Second Report and Order:4 - Solar array area = 60 m2 - Satellite body area (oriented for max antenna exposure) = 4 m2 - Ku-band antenna area = 21 m2 - Total Solar Pressure Area "A" = 85 m2 - Area-to-mass Ratio ("A/,,') = 0.03 1 m2kg - Solar Pressure Radiation Coefficient (worst case) ("CR") = 2 Therefore the Minimum Disposal Orbit Perigee Altitude will be equal to - 36,021 km + 1000 x CRx A/M = 36,021 km + 1000 x 2 x 0.031 m2/kg - 36,083.2 km - 297 km above GSO Approximately 10 kg of propellant will be allocated and reserved for the final orbit raising maneuvers. EchoStar used two methods to calculate this amount. First, it applied the pressure-volume-temperature method, which uses the tank pressure and temperature information to determine remaining propellant. Second, it applied the bookkeeping method, which evaluates the flow rate at average pressure and total thruster on-time of orbital maneuvers to determine the amount of propellant used. EchoStar has assessed fuel gauging uncertainty and has provided an adequate margin of fuel to address such uncertainty. Second Report and Order at 7 68. -3-
