Table 1: Mitigation Requirements for Compliance Page 4 of 21 2.1 Conclusion and Recommendations • The results of the analysis indicate that the power density levels in the generally accessible areas on the Adjacent Roof 1 Level will not exceed the FCC's MPE limit for General Population limit. • The maximum theoretical % MPE is 18.06% directly in front of the antenna beams at the Adjacent Roof 1 Level. • NOC and Guidelines signs need to be posted on the Access Gate to the site. Note: Modifications to the site; and/or increases in channel counts or power levels exceeding those listed in this report will require additional evaluation to determine compliance. Page 5 of 21 3 Introduction The purpose of this analysis and report is to evaluate the cumulative power density levels of all non -excluded antennas located on the site and identify any areas of concern that require mitigation. This report also assesses the site's compliance with FCC OET Bulletin 65; "Guidelines for Human Exposure to Radio -frequency Electromagnetic Fields". The power density simulation performed for this site utilized RoofMaster® analysis software. All antennas were assigned an operating frequency and transmit power and were deemed to be operating at 100% of their rated output power. 3.1 Site Description: • Site Name: Scriber • Street Address: 9920 Edmonds Way Edmonds, WA 98020 • Latitude: 470 47' 22.769" N • Longitude: 1220 21' 57.425" W • Structure Type: Monopole • Structure Height: ± 83' AGL • Co -Locators/ Other Antennas: CD shows Co -locator antennas. Since no co - locator data was provided, a general antenna configuration was used modeling the Unknown carrier. However, until those details can be confirmed in the Post analysis, (Unknown) was used as an identifier in the report. C/Ls were estimated from the CDs. • BTS Equipment Location: The VZW equipment is located on the Ground. Page 6 of 21 3.2 Site Configuration Being Modeled • This is a Monopole application where Verizon antennas are mounted to pipes on the Monopole behind Concealment Shroud for all sectors. • This is a Three -Sector site supporting LTE at 700, 850, 1900, 2100 MHz, 5GNR at 850MHz, and C-Band at 3700 MHz for all sectors. All LTE assumes 4x4 MIMO. • The values of the LTE antennas rad center of all sectors (74.8'), C-Band Antennas (80'), Adjacent Roof 1 Height (19'), Adjacent Roof 2 Height (13'), Adjacent Roof 4 Height (11'), and Adjacent Roof 5 Height (6') are based on the CDs and RFDS. These values must be verified on the site audit for the post study. • The Adjacent Roof 3 has the same height as Adjacent Roof 2. • All technologies were evaluated assuming the maximum number of channels and were running at maximum power 100% of the time. Page 7 of 21 4 Predictive Analysis Details For purposes of this analysis, RoofMasterO was configured to provide an output based on the appropriate MPE limit(s) published in the FCC's guidelines. The antenna information was loaded into RoofMasterO, an MPE predictive analysis tool by Waterford Consultants, LLC. 4.1 Analysis Locations: Number of Elevations Analyzed: 1 Adjacent Roof 1 Level. A study at the Ground level was not required as the study at the Adjacent Roof 1 level shows that the MPE limit is below the General Population MPE limit on the Ground level. Page 8 of 21 4.2 Antenna Inventory The following table contains the technical data used to simulate the power density that may be encountered with all antennas simultaneously operating at full rated power with the exception of any excluded antennas cited in this document. If co -locator's antennas exist and specific antenna details could not be secured, generic antennas, frequencies, and transmit powers were used for modeling. The assumptions used are based on past experience with communications carriers.

Page 14 of 21 7 Appendix A: FCC Compliance and RF Safety Policies In August of 1997, the FCC published OET Bulletin 65 Edition 97-01 to regulate methods for evaluating compliance with FCC guidelines for human exposure to radiofrequency (RF) electromagnetic fields. The FCC guidelines for human exposure to RF electromagnetic fields incorporate two categories of limits; namely "Controlled" (a.k.a. Occupational) and "Uncontrolled" (a.k.a. General Public). The guidelines offer suggested methods for evaluating fixed RF transmitters to ensure that the controlled and uncontrolled limits deemed safe by the FC for human exposure are not exceeded. OET Bulletin 65 recommended guidelines are intended to allow an applicant to "make a reasonably quick determination as to whether a proposed facility is in compliance with the limits." In addition, the guidelines offer alternate supplementary considerations and procedures such as field measurements and more detailed analysis that should be used for multiple emitter situations. These guidelines define RF as emissions in the frequency range of 300 kHz to 100 GHz. The FCC define Maximum Permissible Exposure (MPE) limits within this frequency range based on limits recommended by the National Council on Radiation Protection and Measurement, the Institute of Electrical and Electronics Engineers (IEEE), and by the American National Standards Institute (ANSI). The specific MPE limits defined by the FCC are as follows: Frequency Range [MHz] 0.3 - 3.0 3.0 - 30 30 - 300 300 - 1,500 1,500 - 100,000 Frequency Range [MHz] 0.3 - 3.0 3.0 - 30 30 - 300 300- 1,500 1,500 - 100,000 f = frequency Electric Field Strength (E) [V/m] 614 1842/f 61.4 Electric Field Strength (E) [V/m] 614 842/f 27.5 Occupational/Con Magnetic Field Strength (H) [Alm] 1.63 4.89/f 0.163 Magnetic Field Strength (H) [Alm] 1.63 2.19/f 0.073 ane-wave equ lied Exposure Power Density (S) [mW/Cm^2] 100* 900/f"2* 1 f/300 5 Power Density (S) [mW/Cm^2] 100* 180/f^2* 0.2 f/1500 1 power Averaging Time JEJ"2, IHJ^2 or S [minutes] 6 6 6 6 6 re Averaging Time JEJ"2, IHJ^2 or S [minutes] 30 30 30 30 30 The FCC states that "Occupational/ Controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for Occupational/ Controlled exposure also apply in situations when an individual is transient through a location where Occupational/ Controlled limits apply provided he or she is made aware of the potential for exposure." Page 15 of 21 For General Population/ Uncontrolled limits, the FCC states that "General Population/ Uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not fully be aware of the potential for exposure or cannot exercise control over their exposure." For purposes of this analysis, all limits are evaluated against the Power Density limits. Typical guidelines for determining whether Occupational/ Controlled limits can be applied include ensuring the environment (such as a rooftop) as limited/controlled access via locked doors or physical barrier that are preferably controlled by a landlord that is aware of the situation and can inform anyone going through the locked door of the existence of the RF emissions. Such notification/awareness is typically accomplished by means of signage on the door, or other access to the area of concern, as well as signage on or near the antennas. Examples of such signs include the following: GUIDELINES NOTICE CAUTION WARNING This sign will inform This sign indicates This sign indicates This sign indicates that RF anyone of the basic that RF emissions that RF emissions emissions may exceed at precautions to follow may exceed the FCC may exceed the least 1 Ox the FCC when entering an area General Population FCC Occupational Occupational MPE limit. with transmitting MPE limit.

They will include specific cell site identification 77 information and the Verizon Wireless Network Operations Center phone number. Standards for when to use each of the above signs for Occupational situations are as follows: No sign required: <20% of Occupational MPE Blue Sign, Notice: 20% to <100% of MPE Yellow Sign, Caution: 100% to <1000% of MPE Red Sign, Warning: >1000% of MPE All MPE references are to the FCC Occupational limits. Page 16 of 21 8 Appendix B: Overview of RoofMaster® Functions and Assumptions RoofMaster® is a RF Compliance software package designed to enable the analysis, assessment and mitigation of communications sites with respect to human exposure to radiofrequency electromagnetic fields. RoofMaster® was developed in 2008 by Waterford Consultants to support compliance assessments performed at single and multi -operator wireless locations throughout North America and has been in service since 2008. Real -world experience in evaluating thousands of base station installations is reflected in the RoofMaster® design approach. This document provides a guide for creating simulations of RF hazard conditions through the characterization of antenna systems and site features and through FCC -specified computational analysis. On any structure, one may encounter antennas installed by wireless service providers, public safety and other FCC -licensed and unlicensed operators. Siting constraints have resulted in diverse and complex environments accessible to people performing a variety of activities around these antennas. RoofMaster® supports the characterization of these locations to convey important information regarding RF sources and accessible areas necessary to evaluate the potential for human exposure to hazardous levels of RF energy. RoofMaster® supports the depiction of communications sites through the display of construction drawing or aerial photography image files as well as providing line drawing tools. These representations are scalable to enable the modeling of any location. RoofMaster® utilizes a three-dimensional spatial framework consisting of a 1000 x 1000 grid with unlimited vertical dimensions necessary for the positioning of antennas and modeling of RF conditions at each grid point throughout the space. Predictive analysis is performed on a study plane at a specified elevation. The subsequent sections of this guide provide the steps necessary to create a site representation and conduct these studies. RoofMaster® employs several power density prediction models based on the computational approaches set forth in the Federal Communications Commission's Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, OET Bulletin 65. This guideline utilizes several antenna and operational parameters in calculating the power density contributions from each emitter at specified points throughout the study space. RoofMaster® enables antennas to be fully defined in site specific aspects as well as through the use of a library of manufacturer data. The parameters include: Page 17 of 21 § Antenna model § Radiation patterns § Aperture length § Gain § Beamwidth § Antenna radiation center § Azimuth § Mechanical downtilt § Location § Frequency § Power into antenna In OET-65, the Cylindrical Model is presented as an approach to determine the spatially averaged power density in the near field directly in front of an antenna. In order to implement this model in all directions, RoofMaster® utilizes the antenna manufacturer horizontal pattern data. Additionally, RoofMaster® incorporates factors that reduce the power density by the inverse square of horizontal and vertical distance beyond the near field region. Power density is calculated as follows: S _ 360 )PnGHHrK) pw Beamwidth 2 rRh cni • S is the spatially averaged power density value • R is the horizontal distance meters to the study point • h is the aperture length in meters • Pi, is power into the antenna input port in Watts RoofMaster® Implementation: • Gx is gain offset to study point as specified in manufacturer horizontal pattern • Pi,, is adjusted by the portion of the antenna aperture in the 0-6 ft. vertical study zone • Hr accounts for 1/R2 Far Field roll off which starts at 2*h • Vr accounts for 1/ (vertical distance)2 roll off from antenna bottom to the top of the 0-6 ft. study zone (or antenna top to bottom of 0-6 ft. study zone) Page 18 of 21 t- > Beamwidth Horizontal Distance Page 19 of 21 9 References FCC (1997).
