Supporting Documents Tower Drawings Mapping by TEP Job #03425, dated September 22, 2003 Foundation Drawing Mapping by TEP Job #03425, dated September 22, 2003 Geotechnical Report S&ME Job #1261-03-513, dated October 1, 2003 Analysis The tower was analyzed using American Tower Corporation’s tower analysis software. This program considers an elastic three-dimensional model and second-order effects per ANSI/TIA-222. Basic Wind Speed:97 mph (3-Second Gust) Basic Wind Speed w/ Ice:30 mph (3-Second Gust) w/ 3/4" radial ice concurrent Code:ANSI/TIA-222-G / 2009 IBC / 2012 North Carolina Building Code Structure Class:II Exposure Category:C Topographic Category:1 Spectral Response:Ss = 0.18, S1 = 0.08 Site Class:D - Stiff Soil Conclusion Based on the analysis results, the structure meets the requirements per the applicable codes listed above. The tower and foundation can support the equipment as described in this report. If you have any questions or require additional information, please contact American Tower via email at Engineering@americantower.com. Please include the American Tower site name, site number, and engineering number in the subject line for any questions. Eng. Number OAA692409_C3_01 January 6, 2017 Page 2 A.T.

This information may consist of, but is not necessary limited, to: --Information supplied by the client regarding the structure itself, antenna, mounts and feed line loading on the structure and its components, or other relevant information. --Information from drawings in the possession of American Tower Corporation, or generated by field inspections or measurements of the structure. It is the responsibility of the client to ensure that the information provided to A.T. Engineering Services, PLLC and used in the performance of our engineering services is correct and complete. In the absence of information to the contrary, we assume that all structures were constructed in accordance with the drawings and specifications and that their capacity has not significantly changed from the "as new" condition. Unless explicitly agreed by both the client and American Tower Corporation, all services will be performed in accordance with the current revision of ANSI/TIA -222. The design basic wind speed will be determined based on the minimum basic wind speed as prescribed in ANSI/TIA-222. Although every effort is taken to ensure that the loading considered is adequate to meet the requirements of all applicable regulatory entities, we can provide no assurance to meet any other local and state codes or requirements. If wind and ice loads or other relevant parameters are to be different from the minimum values recommended by the codes, the client shall specify the exact requirement. All services are performed, results obtained, and recommendations made in accordance with generally accepted engineering principles and practices. A.T. Engineering Services, PLLC is not responsible for the conclusions, opinions and recommendations made by others based on the information we supply.
