See attachment for additional condition(s) or information. Based on this evaluation, marking and lighting are not necessary for aviation safety. However, if marking and/or lighting are accomplished on a voluntary basis, we recommend it be installed and maintained in accordance with FAA Advisory Circular 70/7460-1 70/7460-1K. This determination expires on 04/21/2007 unless: (a) extended, revised or terminated by the issuing office. (b) the construction is subject to the licensing authority of the Federal Communications Commission (FCC) and an application for a construction permit has been filed , as required by the FCC, within 6 months of the date of this determination. In such case, the determination expires on the date prescribed by the FCC for completion of construction, or the date the FCC denies the application. NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST BE POSTMARKED OR DELIVERED TO THIS OFFICE AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. This determination is based, in part, on the foregoing description which includes specific coordinates, heights, frequency(ies) and power. Any changes in coordinates, heights, and frequencies or use of greater power will void this determination. Any future construction or alteration, including increase to heights, power, or the addition of other transmitters, requires separate notice to the FAA. Page 1

This determination does include temporary construction equipment such as cranes, derricks, etc., which may be used during actual construction of the structure. However, this equipment shall not exceed the overall heights as indicated above. Equipment which has a height greater than the studied structure requires separate notice to the FAA. This determination concerns the effect of this structure on the safe and efficient use of navigable airspace by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, ordinance, or regulation of any Federal, State, or local government body. A copy of this determination will be forwarded to the Federal Communications Commission if the structure is subject to their licensing authority. If we can be of further assistance, please contact our office at (310)725-6557. On any future correspondence concerning this matter, please refer to Aeronautical Study Number 2005-AWP-3874-OE.

Additional Information for ASN 2005-AWP-3874-OE THE FOLLOWING PROVISION FROM FAA FREQUENCY MANAGEMENT MUST BE MET: FREQUENCIES; 1010.0 MHZ WITH COORDINATION # NG T050306 1025.0 MHZ WITH COORDINATION # NG T050307 1030.0 MHZ WITH COORDINATION # NG T0503010 1060.0 MHZ WITH COORDINATION # NG T050308 1090.0 MHZ WITH COORDINATION # NG T050311 1095.0 MHZ WITH COORDINATION # NG T050309, SHALL BE USED WITH AUTHORIZED POWER OF 0.5 WATT (ERP). THE ASSIGNMENTS ARE AUTHORIZED WITH THE CONDITION THAT THE VERTICAL BEAM WIDTH TOP EDGE DOES NOT EXTEND ABOVE THE DOME OF THE RECEIVING STATION. THE FREQUENCY 1110 MHZ SHALL NOT BE USED DUE TO POTENTIAL OF INTERFERENCE TO FAA FACILITY CRITICAL TO AVIATION SAFETY. ONLY FREQUENCIES 3150 MHZ AND 3450 MHZ WITH 1 WATT (ERP) SHALL BE USED WITHIN THE 3000 MHZ TO 3600 MHZ BAND. THE BAND 3500 MHZ TO 3700 MHZ SHALL NOT BE USED DUE TO POTENTIAL OF INTERFERENCE TO FAA FACILITIES CRITICAL TO AVIATION SAFETY OPERATING IN THAT FREQUENCY BAND. IF TRANSMISSIONS PRESENT INTERFERENCE TO FAA FACILITIES, PROPONENT WILL CEASE TRANSMISSIONS IMMEDIATELY UNTIL INTERFERENCE PROBLEM IS RESOLVED. FCC LICENCE IS REQUIRED PRIOR TO OPERATION. Page 3
