CLEVELAND, OH APRIL 7, 2008 1. CONCLUSIONS Tele-Sci Solutions has performed an Interference Study and Frequency Coordination considering all existing, proposed and prior coordinated microwave facilities within the coordination contours of the proposed Earth Station. This Interference Study and Frequency Coordination demonstrate that this site will operate satisfactorily with the Terrestrial Microwave Environment as defined on the frequency coordination data sheet. 2. SUMMARY OF RESULTS There were no potential great circle interference cases at 4 GHz. There were no potential great circle interference cases at 6 GHz which have not been satisfactorily resolved. There were no reported cases of rain scatter beam intersections at 4 or 6 GHz. 1

3. SUPPLEMENTAL SHOWING The Satellite Earth station proposed in this Application was coordinated by Tele- Sci Solutions, using computer techniques and in accordance with Parts 25 and 101 of the FCC Rules and Regulations. 4. FREQUENCY COORDINATION DATA The attached Frequency Coordination Data contains the following: Technical Characteristics of Proposed Earth Station Horizon Antenna Gain Plot Discrimination Angle Plot Local Horizon Plot Satellite Elevation Plot 4 and 6 GHz Coordination Contour 4 and 6 GHz Rain Scatter 2

5. FREQUENCY COORDINATION STATEMENT (FCC PART 101) Holders of licenses, permittees, prior filed applicants or planners of 6 GHz transmitting stations were notified on March 12, 2008 of the proposed Earth Station technical details in accordance with Section 25.203 (c-2) of the FCC Rules and Regulations.
