(Sitesafe), an independent Radio Frequency (RF) regulatory and engineering consulting firm, to determine whether the proposed communications site, 822887 -Calavera Hills Comm, located at 2997 Glasgow Drive, Carlsbad, CA, is in compliance with Federal Communication Commission (FCC) Rules and Regulations for RF emissions. This report contains a detailed summary of the RF environment at the site including: • Diagram of the site • Inventory of the make / model of all antennas • Theoretical MPE based on modeling This report addresses exposure to radio frequency electromagnetic fields in accordance with the FCC Rules and Regulations for a ll individuals, classified in two groups, "Occupational or Controlled" and "General Public or Uncontrolled." Site is compliant with the FCC rules and regulations, as described in OET Bulletin 65 and will remain compliant upon implementation of the proposed changes. T-Mobile proposes to swap out six (6) existing antennas and replace with six 6 new panel antennas on an existing monopole. The proposed antennas are noted as "proposed" in the antenna table under section 6. This document and the conclusions herein are based on the information provided by Crown Castle. If you have any questions regarding RF safety and regulatory compliance, please do not hesitate to contact Sitesafe's Customer Support Department a t (703) 276- 11 00. 200 N.

The guideline from the FCC Office of Engineering and Technology is Bulletin 65 ("OET Bulletin 65"), Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields, Edition 97-01 , published August 1997. Since 1996 the FCC periodically reviews these rules and regulations as p er their congressional mandate. FCC regulations define two separate tiers of exposure limits: Occupational or "Controlled environment" and General Public or "Uncontrolled environment". The General Public limits are generally five times more conservative or restrictive than the Occupational limit. These limits apply to accessible areas where workers or the general public may be exposed to Radio Frequency (RF) electromagnetic fields. Occupational or Controlled limits apply in situations in which persons are exposed as a consequence of their employment and w here those persons exposed have been made fully aware of the potential for exposure and can exercise contro l over their exposure. An area is considered a Controlled environment when access is limited to these aware personnel. Typical criteria are restricted access (i.e. locked or alarmed doors, barriers, etc.) to the areas where antennas are located coupled with proper RF warning signage. A site with Controlled environments is evaluated with Occupational limits. All other areas are considered Uncontrolled environments. If a site has no access controls or no RF warning signage it is evaluated with General Public limits. The theoretical modeling of the RF electromagnetic fields has been performed in accordance with OET Bulletin 65. The Maximum Permissible Exposure (MPE) limits utilized in this analysis are outlined in the following diagram: FCC Limits for Maximum Permissible Exposure (MPE) Plane-wave Equivalent Power Density 1000 ~---------;:::::==-====--Occupational --General Public 0.01 -1---------~---~ 0 10 100 1,000 10,000 Frequency (MHz) 200 N.

The General Duty clause in Section 5 states: (a) Each employer- ( 1 ) shall furnish to each of his employees employment and a place of employment which ore free from recognized hazards that ore causing or ore likely to cause death or serious physical harm to his employees; (2) shall comply with occupational safety and health standards promulgated under this Act. (b) Eac h employee shall comply with occupational safe ty and health standards and all rules, regulations, and orders issued pursuant to this Act which ore applicable to his own actions and conduct. OSHA hos defined Rodiofrequency and Microwave Radiation safety standards for workers who may enter hazardous RF areas.

The compliance determination is based on theoretical modeling, RF signage p lacement recommendations, proposed antenna inventory and the level of restricted access to the antennas at the site. Any deviation from the T-Mobile's propose d deployment plan could result in the site being rendered non-compliant. 3.2 Actions for Site Compliance Based on common industry practice and our understanding of FCC and OSHA requirements, this section provides a statement of recommendations for site compliance. Site is compliant with the FCC rules and regulations and will remain compliant upon implementation of the proposed changes. 200 N.

General Maintenance Work: Any maintenance personnel required to work immediately in front of a ntennas and / or in areas indicated as above 100% of the Occupational MPE limits should coordinate with the wireless operators to disable transmitters during their work activities. Training and Qualification Verification: All personnel accessing areas indicated as exceeding the General Population MPE limits should have a basic understanding of EME awareness and RF Safety procedures when working around transmitting antennas. Awareness training increases a workers understanding to potential RF exposure scenarios. Awareness can be achieved in a number of ways (e.g. videos, formal classroom lecture or internet based courses). Physical Access Control: Access restrictions to transmitting antennas locations is the primary element in a site safety plan. Examples of access restric tions are as follows: • Locked door or gate • Alarmed door • Locked ladder access • Restrictive Barrier at antenna (e.g. Chain link with posted RF Sign) RF Signage: Everyone should obey all posted signs at all times. RF signs play an important role in properly warning a worker prior to entering into a potential RF Exposure area. Assume all antennas are active: Due to the nature of telecommunications transmissions, an antenna transmits intermittently. Always assume an antenna is transmitting. Never stop in front of an antenna. If you have to pass by an antenna, move through as quickly and safely as possible thereby reducing any exposure to a minimum. Maintain a 3 foot clearance from all antennas: There is a direct correlation between the strength of an EME field and the distance from the transmitting antenna. The further away from an antenna, the lower the corresponding EME field is. Site RF Emissions Diagram: Section 5 of this report contains an RF Diagram that outlines various theoretical Maximum Permissible Exposure (MPE) areas at the site. The modeling is a worst case scenario assuming a duty cycle of 100% for each transmitting antenna a t full power. This analysis is based on one of two access control criteria: General Public criteria means the access to the site is uncontrolled and anyone can gain access. Occupational criteria means the access is restricted and only properly trained individuals can gain access to the antenna locations. 200 N. Glebe Road• Suite 1000 • Arlington, VA 22203-3728 703.276.1100 • info@sitesafe.com Page 7 5 Analysis 5.1 RF Emissions Diagram The RF diagram(s) below display theoretical spatially averaged percentage of the Maximum Permissible Exposure for all systems a t the site unless otherwise noted. These diagrams use modeling as prescribed in OET Bulletin 65 and assumptions detailed in Appendix B. The key at the bottom of each diagra m indicates if percentages displayed are referenced to FCC General Population Maximum Permissible Exposure (MPE) limits. Color coding on the diagram is as follows: • Gray represents areas predicted to be at 5% of the MPE limits, or below. • Green represents areas predicted to be between 5% and 100% of the MPE limits. • Blue represents areas predicted to be between 100% and 500% of the MPE limits. • Yellow represents areas predicted to be b etween 500% and 5000% of the MPE limits. • Red areas indicated predicted levels greater than 5000% of the MPE limits . General Population diagrams are specified when an area is accessible to the public; i.e. personnel that do not meet Occupational or RF Safety trained criteria, could gain access. If trained occupational personnel require access to areas that ore delineated as Blue or above l 00% of the limit, Sitesafe recommends that they utilize the proper personal protection equipment (RF monitors), coordina te with the carriers to reduce or shutdown power, or make real-time power density measurements with the appropriate power density meter to determine real-time MPE levels. This will allow the personnel to ensure that their work area is within exposure limits. The key at the bottom also indicates the level or height of the modeling with respect to the main level. The origin is typically referenced to the main rooftop level, or ground level for a structure w ithout access to the antenna level. For example: Average from O feet above to 6 feet above origin and Average from 20 feet above to 26 feet above origin The first indicates modeling at the main rooftop (or ground) level averaged over 6 feet. The second indicates modeling at a higher level (possibly a penthouse level) of 20 feet averaged over 6 feet.

Due to the complexity of some wireless sites, Sitesafe performed this analysis and created this report utilizing b est industry practices and due diligence. Sitesafe cannot be held a ccountable or responsible for anomalies or discrepancies due to actual site conditions (i.e., mislabeling of antennas or equipment, inaccessible cable runs, inaccessible antennas or equipment, etc.) or information or data supplied by T-Mobile, the site manager, or their affiliates, subcontrac tors or assigns. Sitesafe has provided computer generated model(s) in this Site Compliance Report to show approximate dimensions of the site, and the model is included to assist the reader of the compliance report to visualize the site area, and to provide supporting documentation for Sitesafe's recommendations. Sitesafe may note in the Site Compliance Report any adverse physical conditions, such as needed repairs, observed during the survey of the subject property or that Sitesafe became aware of during the normal research involved in performing this survey. Sitesafe will not be responsible for any such conditions that do exist or for any engineering or testing that might be required to discover whether such conditions exist. Because Sitesafe is not an expert in the field of mechanical engineeri ng or building maintenance, the Site Compliance Report must not be considered a structural or physical engineering report. Sitesafe obtained information used in this Site Compliance Report from sources that Sitesafe considers reliable and believes them to b e true and correct. Sitesafe does not assume any responsibility for the accuracy of such items that were furnished by other parties. When conflicts in information occur between data provided by a second party and physical data collected by Sitesafe, the physical data will be used . 200 N. Glebe Road• Suite 1000 • Arlington, VA 22203-3728 703.276.1100 • info@sitesafe.com Page 14 Appendix B -Assumptions and Definitions General Model Assumptions In this site compliance report, it is assumed that a ll antennas are operating at full power at all times. Software modeling was performed for all transmitting antennas located on the site. Sitesafe has further assumed a 100% duty cycle and maximum radiated power. The site has been modeled with these assumptions to show the maximum RF energy density. Sitesafe believes this to be a worst-case a nalysis, based on best available data. Areas modeled to predict emissions greater than 100% of the applicable MPE level may not actually occur, but are shown as a worst-case prediction that could be realized real time. Sitesafe believes these areas to be safe for entry by occupationally trained personnel utilizing appropriate personal protective equipment (in most cases, a personal monitor). Thus, at any time, if power density measurements were made, we believe the real- time measurements would indicate levels below those depicted in the RF emission diagram(s) in this report. By modeling in this way, Sitesafe has conservatively shown exclusion areas -areas that should not be entered without the use of a personal monitor, carriers reducing power, or performing real-time measurements to indicate real-time exposure levels. Use of Generic Antennas For the purposes of this report, the use of "Generic" as an antenna model, or "Unknown" for an operator means the information about a carrier, their FCC license and/or antenna information was not provided and could not be obtained while on site. In the event of unknown information, Sitesafe will use our industry specific knowledge of equipment, antenna models, a nd transmit power to model the site. If more specific information can be obtained for the unknown measurement criteria, Sitesafe recommends remodeling of the site utilizing the more complete and accurate data. Information about similar facilities is used when the service is identified and associated with a particular antenna. If no information is available regarding the transmitting service associated with a n unidentified antenna, using the antenna manufacturer's published data regarding the antenna's physical characteristics makes more conservative assumptions. Where the frequency is unknown, Sitesafe uses the closest frequency in the antenna's range that corresponds to the highest Maximum Permissible Exposure (MPE), resulting in a conservative analysis. 200 N.

Definitions 5% Rule -The rules adopted by the FCC specify that, in general, at multiple transmitter sites actions necessary to bring the area into compliance with the guidelines are the shared responsibility of all licensees whose transmitters produce field strengths or power density levels at the area in question in excess of 5% of the exposure limits. In other words, any wireless operator that contributes 5% or greater of the MPE limit in an area that is identified to be greater than l 00% of the MPE limit is responsible taking corrective actions to bring the site into compliance. Compliance -The determination of whether a site is safe or not with regards to Human Exposure to Radio Frequency Radiation from transmitting antennas. Decibel (dB) -A unit for measuring power or strength of a signal. Duty Cycle -The percent of pulse duration to the pulse period of a periodic pulse train. Also, may be a measure of the temporal transmission characteristic of an intermittently transmitting RF source such as a paging antenna by dividing average transmission duration by the average period for transmission. A duty cycle of 100% corresponds to continuous operation. Effective (or Equivalent) Isotropic Radiated Power (EIRP) -The product of the power supplied to the antenna and the antenna gain in a given direction relative to an isotropic antenna. Effective Radiated Power (ERP) -In a given direction, the relative gain of a transmitting antenna with respect to the maximum directivity of a half wave dipole multiplied by the net power accepted by the antenna from the connecting transmitter. Gain (of an antenna) -The ratio of the maximum intensity in a given direction to the maximum radiation in the same direction from an isotropic radiator. Gain is a measure of the relative e fficiency of a directional antennas as compared to an omni directional antenna. General Population/Uncontrolled Environment -Defined by the FCC, as an area where RFR exposure may occur to persons who are unaware of the potential for exposure and who have no control of their exposure. General Population is also referenced as General Public. Generic Antenna -For the purposes of this report, the use of "Generic" as an antenna model means the antenna information was not provided and could not be obtained while on site. In the event of unknown information, Sitesafe will use our industry specifi c knowledge of antenna models to select a worst case scenario antenna to model the site. Isotropic Antenna -An antenna that is completely non-directional. In other words, an antenna that radiates energy equally in all directions. Maximum Measurement -This measurement represents the single largest measurement recorded when performing a spatial overage measurement. 200 N. Glebe Road• Suite 1000 • Arlington, VA 22203-3728 703.276.1100 • info@sitesafe.com Page 16 Maximum Permissible Exposure (MPE) -The rms and peak electric and magnetic field strength, their squares, or the plane-wave equivalent power densities associated with these fields to which a person may be exposed without harmful effect and w ith acceptable safety factor. Occupational/Controlled Environment -Defined by the FCC, as an area where Radio Frequency Radiation (RFR) exposure may occur to persons who are aware of the potential for exposure as a condition of employment or specific activity and can exercise control over their exposure. OET Bulletin 65 -Technical guideline developed by the FCC's Office of Engineering and Technology to determine the impact o f Radio Frequency radiation on Humans. The guideline was published in August 1997 . OSHA (Occupational Safety and Health Administration) -Under the Occupational Safety and Health Act of 1970, employers are responsible for providing a safe and healthy workplace for their employees. OSHA's role is to promote the safety and health of America's working men and women by setting and enforcing standards; providing training, outreach and education; establishing partnerships; and encouraging continual process improvement in workplace safety and health.

Appendix C -Rules & Regulations Explanation of Applicable Rules and Regulations The FCC has set forth guidelines in OET Bulletin 65 for human exposure to radio frequency electromagnetic fields. Specific regula tions regarding this topic are listed in Part l , Subpart I, of Title 47 in the Code of Federal Regulations. Currently, there are two different levels of MPE -General Public MPE and Occupational MPE. An individual classified as Occupational can be defined as an individual w ho has received appropriate RF training and meets the conditions outlined below. General Public is defined as anyone w ho does not meet the conditions of being Occupational. FCC and OS HA Rules and Regulations define compliance in terms of total exposure to total RF energy, regardless of location of or proximity to the sources of energy. It is the responsibility of all licensees to ensure these guidelines ore maintained at all times. It is the ongoing responsibility of all licensees composing the site to maintain ongoing compliance with FCC rules and regulations. Individual licensees that contribute less than 5% MPE to any total area out of compliance ore not responsible for corrective actions. OSHA hos adopted and enforces the FCC's exposure guidelines. A building owner or site manager can use this report as part of on overall RF Health and Safety Policy. It is important for building owners/site managers to identify areas in excess of the General Population MPE and e nsure that only persons qualified as Occupational are granted access to those areas. Occupational Environment Explained The FCC definition of Occupational exposure limits apply to persons who: • are exposed to RF energy as a consequence of their employm ent; • hove been mode aware of the possibility of exposure; and • con exercise control over their exposure. OSHA guidelines go further to state that persons must complete RF Safety Awareness training and must be trained in th e use of appropriate personal protective equipment. In order to consider this site on Occupational Environment, the site must be controlled to prevent access by any individuals classified as the General Public. Compliance is also maintained when any non-occupational individuals {the General Public) are prevented from accessing areas indicated as Red or Yellow in the attached RF Emissions diagram. In addition, a person must be aware of the RF environment into w hich they are entering. This con be accomplished by on RF Safety Awareness class, and by appropriate written documentation such as this Site Compliance Report . All T-Mobile employees who require access to this site must complete RF Safety Awareness training and must be trained in the use of appropriate personal protective equipment. 200 N.

Appendix D -General Safety Recommendations The following are general recommendations appropriate for any site with accessible areas in excess of l 00% General Public MPE. These recommendations are not specific to this site. These are safety recommendations appropriate for typical site management, building management, and other tenant operations. l. All individuals needing access to the main site (or the area indicated to be in excess of General Public MPE) should wear a personal RF Exposure monitor, successfully complete proper RF Safety Awareness traini ng, and have and be trained in the use of appropriate personal protective equipment. 2. All individuals needing access to the main site should be instructed to read and obey all posted placards and signs. 3. The site should be routinely inspected and this or similar report updated with the addition of any antennas or upon any changes to the RF environment inc luding: • adding new antennas that may have been located on the site • removing of any existing antennas • changes in the radiating power or number of RF emitters 4. Post the appropriate NOTICE, CAUTION, or WARNING sign at the main site access point(s) and other locations as required. Note: Please refer to RF Exposure Diagrams in Appendix B, to inform everyone w ho has access to this site that beyond posted signs there may be levels in excess of the limits prescribed by the FCC. The signs below are examples of signs meeting FCC guidelines.

Ensure that the site door remains locked (or appropriately controlled) to deny access to the general public if deemed as policy by the building/site owner. 6. For a General Public environment the four color levels identified in this analysis can be interpreted in the following manner: • Gray represents area at below 5% of the General Public MPE limits or below. This level is safe for a worker to be in at any time. • Green represents areas predicted to be between 5% and l 00% of the General Public MPE limits. This level is safe for a worker to be in a t any time. 200 N. Glebe Road• Suite 1000 • Arlington, VA 22203-3728 703.27 6.1100 • info@sitesafe.com Page 19 A tlUBn•••• DJ." I-OM VCLDCITIIL • Blue represents areas predicted to be between l 00% and 500% of the General Public MPE limits. This level is safe for a worker to be in at any time. • Yellow represents areas predicted to be between 500% and 5000% of the General Public MPE limits. This level is safe for a worker to be in. • Red areas indicated predicted levels greater than 5000% of the General Public MPE limits. This level is not safe for the General Public to be in. 7. For an Occupational environment the five color levels identified in this analysis can be interpreted in the following manner: • Areas indicated as Gray are at 5% of the Occupational MPE limits or below. This level is safe for a worker to be in at any time. • Green represents areas predicted to be between 5% and 20% of the Occupational MPE limits. This level is safe for a worker to be in at any time. • Blue represents areas predicted to be between 20% and l 00% o f the Occupational MPE limits. This level is safe for a worker to be in at any time. • Yellow represents areas predicted to be between 100% and 500% of the Occupational MPE limits. Only individuals that have been properly trained in RF Health and Safety should be allowed to work in this area. This is not an area that is suitable for the General Public to be in.s • Red areas indicated predicted levels greater than 500% of the Occupational MPE limits. This level is not safe for the Occupational worker to be in for prolonged periods of time. Special procedures must be adhered to such as lock out tag out procedures to minimize the workers exposure to EME. 8. Use of a Personal Protective Monitor: When working around antennas, Sitesafe strong recommends the use of a Personal Protective Monitor (PPM). Wearing a PPM will properly forewarn the individual prior to entering an RF exposure area. Keep a copy of this report available for all persons who must access the site. They should read this report and be aware of the potential hazards with regards to RF and MPE limits.
