AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-15-17 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 agricultural or 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 sties were relatively commensurate in terms of the probability of successful completion of the project. Big Bend had the most receptive landlord with the best property •The primary site (Big Bend) was therefore chosen because a new build was necessary and because there is a high probability of obtaining a successful lease. CVL01754 – Primary Site Location AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-15-17 Page 6 •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 1 – Potan Place – New build at Potan Place AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-15-17 Page 8 •Bunker Hill at 7007 Bunker Hill Mine Road, Oroville, CA 95965 •While both the primary site candidate and this alternate site candidate were commensurate in probability of having a successfully completed project when initial inquiries were taken; the alternate site (Bunker Hill) the site was a lower elevation and lacked sufficient free space for installation of a tower. •This site was discarded in favor of the primary candidate because of a more responsive landlord. Alternative 2 – Bunker Hill – New build at the Bunker Hill AT&T RESTRICTED CONFIDENTIAL AND PRIVILEGED ATTORNEY CLIENT COMMUNICATION Rev.0 05-15-17 Page 9 Conclusion Based on AT&T’s analysis of alternative sites, our engineering staff has confirmed that the Primary site location at 10829 Little Bend Court 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.
