The amended statement being filed today correets that omission. If you have any questions about this filig, please contact the undersigned.

IN—ORBIT COLLISION STATEMENT FOR 121° W.L. In considering operational and planned satellites that may have a station—keeping volume that overlaps the ECHOSTAR—121W—KuX satellte, EchoStar reviewed the lists of FCC Hicensed systems and systems 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 121° W.L., have also been reviewed.. Only those networks that cither operate, or are planned to operate, and can have an overlapping station—keeping volume with the ECHOSTAR—121 W—KuX satellite have been taken into account in the analysis. For purposes ofcalculating potentialstation—keeping volume overiap, US satellites have beenassumed to have a maximum east—west excursion 00.05° from their nominal location, while non—US satelite networks have been assumed to have a maximum excursion of0.1° from their nominal location. Based on oureview, there are no pending applications for a satllite network in the immediate vicinity of 121°W.L. EchoStar operates the Ku/Ka—band ECHOSTAR—IX satellte at 121°W.L. The satellite also includes a C—band payload operated by INTELSAT North America L.L.C., operating under the authority ofPapua New Guinea via the PACSTAR—L4 ITU network, and is authorized by the Commission to provide services to and from the U.S. EchoStar manages the fight control ofthe ECHOSTAR—IX satellte. The UK has submitted a request for coordination for the GIBSAT A2 network at 121°W.L. EchoStar can find no evidence thata satellite construction contract has been

awarded for this satelite, nor does the Federal Aviation Administration Commercial Space Station Fourth Quarter 2004 Report show a pending launch for a UK—authorized satellite to the 12I°W.L. location. Celsat America, Inc. ("Celsat")is authorized to operate a S— and Ka—band satellte at 1219 W.L. Physical coordination ofthe EchoStar and Celsatsatelltes will be required. EchoStar will begin coordination with Celsat approximately two years before the expected launch of the ECHOSTAR—121 W—KuX satellite. There are a number ofpotential fight dymamic solutions to be explored in consultation with Celsatto ensure avoidance of in—orbit collision between the satelltes, including the possibility ofoperating the satellites at small angular offsets from their nominal position. In the event tat a coordination agreement requires operation ofthe ECHOSTAR—121 W KuX satellit at an offset from its assigned nominal position, EchoStar will seek any necessary modifications to its authorization from the Commission.
