EXHIBIT 1 ITEM 4a: FREQUENCY THIS STATION IS DESIGNED TO OPERATE ON ONE OF 600 CHANNELS SPACED AT 50 KHZ INTERVALS IN THE 420—450 MHZ BAND, WITH ONE OF THESE BANDWIDTHS (ITEM 4G) AND CORRESPONDING MODULA— TING SIGNAL (ITEM 4F). EXHIBIT 2 ITEM 7: OPERATIONS UNDER THIS LICENSE WERE CONDUCTED FOR THE PURPOSE OF TEST AND EVALUATION OF A FUTURE AIRBORNE EARLY WARNING RADAR SOLID STATE MODULE ANTENNA. TO PROVIDE FOR SYSTEM INTEGRATION REQUIREMENTS, AND TO ASSESS OVERALL PERFORMANCE ON GROUND BEFORE FLIGHT. THE PROJECT INITIALLY WAS AN ADVANCED DEVELOPMENT PROGRAM CALLED THE GRUMMAN CONFORMAL RADAR PROGRAM, LATER, IT WAS FUNDED BY U.S. NAVY UNDER CONTRACT AND BECAME KNOWN AS WING ARRAY DEMONSTATOR. MODIFICATION OF STATION KS82XDR IS NECESSARY TO MEET THE PRESENT AND ANY FUTURE CONTRACTUAL REQUIREMENTS. AN UPDATED ENVIORNMENTAL IMPACT STUDY IS INCLUDED TO FULFIL REQUIREMENTS SET FORTH BY THE COMMISSION. CURRENT U.S. NAVY CONTRACT # is N62269—84—C—0371

FROM 11.12. 1992 10134 P .4 2 ENVIRONNENTAL IMPACT STATENENE For ConFORrNAL RAbAR TRANSHITTER The ground arca covorcd by tho Conformal Radar baam can be divided into four distinct eactions, see accompanying eketch: "Near #Ficl4" extending from weatr facae of Plant 14 to 45 feet westward of Plant 14. "Naar Field" extonding from 45 foeet weat of Plant 1+i to 300 faet weset of Plant 14 . "Far Field" extonding from 300 fcoct wesat of Plant 14 to ho r1zon . "S1delobe and backloba" axtending from antenne room to horigson in all directions except front of antenna. Ar e a 1 from west faco of Plant 1h to 45 feet weet of Plant 14 and extending from 218° to 308° is in the near field of the antenna (Aee accompanying sketch), hbowever thae baam into this direction will be blockod by antenna room shielding and absorber material of at least 60 4B attenuation. Frobing of this area will confirm that this arca is safe for human exposure at all times. Aar e a from 45 fest west of Plant 14 to 300 foot woeaet of Plant 14 and extending from 218"° io 308"° is in the near field of the antaenna (see detail in accompanying sketch). The energy intensity and diatribution in the neat field is not predictable by calculation with Lormulae, becaunsee in this area the energy hbeam is not fuily formed . Upon completion of tho tranomitter installation and prior to turn on, the area will be cleared of all humans. Tho transmitter will be turned on and tha ares wvill be probed by soafoty personnel with appropriate teet equipment . In case energy leveloe greater than thove allowed by ANSI C95.1—1902 are detected, deflection screconse and absorber materialse will bo inatoliod in the approprite locations of the antenna beam to provide a safe level of electromagnetic anergy in the eantira aroa 2. The area will ba probed again and abova procedures repeated until the enfirc arcea 2 is safe for human axpnaure at all) times. 2" .‘\
