AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-23-17 Page 4 •Upon review of the region AT&T found no locations that would provide collocation within the search ring. The majority of the search ring region is open natural land so a new build tower becomes essential. •After initially approaching several landlords in the region, three proved the most interested. All three sites were relatively commensurate in terms of the probability of a successful completion of the project. Cribbage lacked sufficient space to accommodate a tower structure, and Tweedy landlord became disinterested. Concow had the highest elevation and the most responsive landlord. •The primary site (Concow) was therefore chosen because a new build was necessary and because there is the highest probability of obtaining a successful lease. CVL02163 – Primary Site Location AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-23-17 Page 5 Proposed Site Location •RF modeling predicts this will be the expanded coverage with the proposed site installed. •This location and elevation is considered to be “optimal” as a permanent site.

Alternative 2 – Tweedy – New build at the Tweedy AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-23-17 Page 9 Conclusion Based on AT&T’s analysis of alternative sites, our engineering staff has confirmed that the Primary site location at 13032 Concow Road remains the most appropriate site for new build construction in this area.

The tool has several GIS layers as inputs such as ground clutter data and average ground elevation height. The tool also knows about our antennas that we use for the cell sites and the transmit powers and everything in the link budget. This tool simulates what a customer will receive as a signal power. This tool is used to compare future site choices so that the optimal coverage can be attained. •Google Earth Pro A powerful GIS tool which is used to overlay the ATOLL prediction and drive test data. With this data and the topography models in this program, further analysis of data and graphic displays of coverage areas can be generated for reference.
