RAE collected bulk samples of building materials suspected to contain asbestos which are to be impacted during remediation activities as a result of the recent renovations. All field activities were performed by Hans Reinisch, a representative of RAE and California Division of Occupational Safety and Health (DOSH) Certified Asbestos Consultant; (CAC#18-6382). 2.0 Asbestos Laboratory Accreditation & Analytical Methods Samples collected for asbestos content were analyzed by Environmental Protection Agency (EPA) Method 600/R-93/116 and/or 600/M4-82-020 per the Code of Federal Regulations (CFR) Title 40 Part 763.86 using Polarized Light Microscopy (PLM) by the following independent and accredited laboratory: •Patriot Environmental Laboratory Services, Inc. - 6640 Lusk Boulevard, Building A, Suite 100 - 101, San Diego, California 92121. National Institute of Standards and Technology/NationalVoluntary Laboratory Accreditation Program (NIST/NVLAP) Lab Code (200982-0). 3.0 ASBESTOS 3.1 Asbestos Sampling Protocol Sampling activities were performed in compliance with the National Emissions Standard for Hazardous Air Pollutants (NESHAP) regulation 40 CFR (Code of Federal Regulations), Part 61, Subpart M. The Environmental Protection Agency (EPA) has designed a protocol in which the sampling of suspect materials is to take place. Materials shall be considered homogeneous if they are similar in color and texture. A homogenous material shall be considered to contain asbestos if any of the samples collected representing that material indicate the presence of asbestos. Contrarily, a homogenous material shall be considered to not contain asbestos only if all of the samples collected representing that material indicate the absence of asbestos. The EPA and California Occupational Safety and Health Administration (Cal-OSHA) have defined building materials containing asbestos as follows: •Asbestos-Containing-Material (ACM) - any material containing greater than 1 percent (>1%)asbestos as determined by PLM, 40 Code of Federal Regulations (CFR) Part 61, Subpart M. Rarefied Air Environmental- 9921 Carmel Mountain Road, #164 San Diego, California 92129 •Asbestos-Containing-Construction-Material (ACCM) - any material containing less than onepercent (<1%) asbestos and greater than one tenth of one percent (>0.1%) asbestos by weight,California Code of Regulations (CCR), Title 8, Section 1529. 3.2 Asbestos Sample Results RAE collected a total of fourteen (14) bulk samples for asbestos content. In accordance with EPA bulk sampling method protocols, the laboratory must separate and analyze all layers within a single sample, resulting in additional sample analysis. The following table summarizes the building materials sampled that were found to contain asbestos based on the limitations of the analytical method: Table I: Asbestos-Containing Materials and/or Asbestos-Containing Construction-Materials Sample # Material Material Location Results Est. Qty. Condition Friable Y/N 012 – 014 Stucco Exterior <1% CH* 1,000 sq. ft. G N No asbestos was detected in any of the other samples collected based on the limitations of the analytical method. The following table summarizes the building materials samples that were found to contain no asbestos based on the limitations of the analytical method: Table II: Materials with No Asbestos Detected Sample # Material Material Location 001 – 005 Drywall and joint compound Living Room, Dining Room, Kitchen, Family Room, Hall Bathroom, Guest Bathroom, SW Bedroom, Master Bathroom, West Bedroom, Master Bedroom and Hallway 006 – 008 Texture coating Living Room, Dining Room, Kitchen, Family Room, Hall Bathroom, Guest Bathroom, SW Bedroom, Master Bathroom, West Bedroom, Master Bedroom and Hallway 009 – 011 Grey blown-in insulation Attic, Living Room, Master Bedroom, Hallway, Master Bedroom and Hall Bathroom Legend * - Material contains trace amounts of asbestos and may be regulated under Cal/OSHA guidelines as an ACCM. The material may be required tobe removed by an asbestos licensed contractor. However, the material is not considered asbestos waste.CH – Chrysotile AsbestosNAD – No Asbestos DetectedG = Good, D = Damaged, SD = Significantly DamagedFriable- any material that can be crumbled, pulverized or reduced to powder by hand pressure. A copy of the asbestos PLM analytical results and chain of custody are included as an attachment to this document. 3.3 Asbestos Recommendations Due to the presence of asbestos, any work that will disturb any of the above referenced asbestos-containing materials (ACM’s) and/or asbestos-containing construction materials (ACCM’s) as a result of planned or other renovations to the subject property must comply with all applicable local, state and federal regulations governing the removal and/or disturbance of ACM’s and/or ACCM’s. 3.4 Disposal Any materials containing greater than 1% asbestos are subject to regulations under EPA (National Emission Standards for Hazardous Air Pollutants [NESHAP]) governing the storage, transportation and disposal of hazardous waste. If any materials contain less than 1% asbestos (and no lead-based paint is present), these Rarefied Air Environmental- 9921 Carmel Mountain Road, #164 San Diego, California 92129 materials may be properly bagged and disposed of as construction debris. If neither asbestos nor lead-based- paint is present, the material may be disposed of as construction debris. NESHAP has allowed for the composite sampling of drywall and joint compound for disposal purposes only. If the drywall and joint compound composite sample results indicate a content of less than (<) 1% asbestos, the drywall and joint compound may be properly bagged and disposed of as construction debris, regardless of the asbestos content of the joint compound itself. If the drywall and joint compound composite sample results indicate a content of greater than (>) 1% asbestos, then this material must be disposed of as hazardous waste. If the drywall and joint compound contain a texture coating with an asbestos content greater than (>) 1%, the drywall and joint compound with texture coating must be disposed of as hazardous waste. Limitations Although Rarefied Air Environmental has taken several precautions in order to find all of the visible suspect asbestos-containing-materials and/or lead-containing-paints present, several factors can hinder the findings at the time of the survey. The following factors should always be considered: • Additional suspect materials could be located between walls, in voids, or in other concealed areas previously inaccessible. If any suspect materials or painted surfaces are found which have not beenrepresented in this report, RAE recommends that work stops until those materials can be sampledfor asbestos and/or lead content. Furthermore, this is a limited survey. Additional suspect materials and paints may be present outside of the affected areas sampled. •RAE does not warrant, guarantee or profess to have the ability to locate or identify all asbestos-containing materials in a facility. •Confined spaces, and areas determined by RAE’s personnel as unsafe to access, are excluded fromthe scope of work. •RAE is not responsible for the validity of the laboratory data. We merely interpret the results provided by the laboratory analysis. •RAE does not guarantee or warrant that the facility or workplace is safe; nor does RAE’sinvolvement in this property relieve the Client, building owner/operator or tenant of any continuing responsibility of providing a safe facility or living space. •This report was based on those conditions observed on the day the field evaluation wasaccomplished. In the event that changes in the nature of the property have occurred, or additional relevant information about the property is subsequently discovered, the findings contained in thisreport may not be valid unless these changes and additional relevant information are reviewed and the conclusion of this report is modified and verified in writing.

(RAE) performed a Limited Preliminary Mold Site Assessment of the above-referenced property. The site assessment was performed as part of the contingency portion of escrow. The site assessment included the collection of bioaerosol air samples, surface swab samples, moisture measurements, temperature and relative humidity percentage readings and a visual assessment aided by the use of a thermal imaging camera. All field activities were performed in general accordance with applicable government and industry standards by trained Environmental Consultant Hans Reinisch. 2.0 SITE ASSESSMENT 2.1 Visual Observations As an initial part of the site assessment, RAE made visual observations of the impacted areas in question. The following issues were observed: 1.Living Room- east wall has elevated moisture and water damage surrounding window due toexterior water intrusion. Window/brick sill allows for water intrusion 2. Dining Room- elevated moisture in north wall 3.Kitchen- west wall under sink had visible suspect growth from previous repair that was doneimproperly 4.Family Room- wet ceiling in an approximate 8’x8’ section stemming from upstairs HVACcondensation line issues 5.Family Room Bar- drywall behind cabinet moist 6. Downstairs Guest Bathroom- water damage to base shelf of cabinet 7.Upstairs Hallway- portion of ceiling collapsed due to HVAC condensate line issues with waterdamage also present of north and west walls Rarefied Air Environmental- 9921 Carmel Mountain Road, #164 San Diego, California 92129 8. Upstairs Hallway Bathroom- water staining behind vanity cabinet and base shelf 9. S/W Bedroom- roof leak caused water damage to ceiling 10. West Bedroom- closet has wet walls, ceiling and carpet 11. Master Bedroom- south and east walls have water damage 12. Master Bathroom- water damage to vanity cabinetry and drywall and ceiling damage 2.2 Moisture Measurements In order to evaluate the moisture content of building materials while on site, RAE utilized an Extech M0290 moisture meter. The moisture meter is a hand-held device utilized to measure the moisture content within a given material. The moisture meter can either operate by use of the pin less pad on the back of the instrument or by a remote pin adaption for more intrusive measurements under the surface of the material. When certain materials are deemed “moist, wet and/or saturated,” via the moisture meter, this is a good indication that fungal growth may begin or continue to proliferate on the given material. However, it should be noted that materials that have dried out over time may still show signs of fungal growth. RAE determines the moisture content of materials using two different forms of measurements: • Reference Scale- this method utilizes the relative moisture content (RMC) setting of the moisture meter. This is not an exact percentage of the moisture content within a material, rather a number readout from a scale of 0-100. This method is typically used on such materials as gypsum wallboard (“drywall”), plaster, carpet, concrete and vinyl. A background or “control” reading is taken of the suspect material in an unaffected area. Generally, a material will be considered moist if the RMC is approximately 6-10 points greater than that of the control reading collected while on site. Anything greater than 10 points above the control reading may be assumed to be saturated. • Wood Moisture Equivalent- this setting of the moisture meter is typically used to measure the moisture content (%MC) of wood components. Generally, moisture content in wood above 16% can support fungal growth. Moisture content at 20% or greater may result in the decomposition of wood components. The following table summarizes the moisture measurements RAE collected while on site: Table I: Summary of Moisture Measurements MOISTURE MEASUREMENTS Room Substrate Sample Location RMC (Control) RMC %MC (Wood) Acceptable (Y/N) CONTROL WALL: Living Room Drywall East wall 7-10 Kitchen Drywall West wall behind sink 8-10 Y Family Room Drywall Ceiling 10-99 N Rarefied Air Environmental- 9921 Carmel Mountain Road, #164 San Diego, California 92129 Table I: Summary of Moisture Measurements (Continued) MOISTURE MEASUREMENTS Room Substrate Sample Location RMC (Control) RMC %MC (Wood) Acceptable (Y/N) Dining Room Drywall North wall 7-64 N Living Room Drywall East wall 10-99 N SW Bedroom Drywall South wall 8-10 Y SW Bedroom Drywall Ceiling by cracks 8-11 Y West Bedroom Drywall Closet east wall north end 99 N West Bedroom Drywall Ceiling 10-65 N West Bedroom Carpet Closet 4-51 N Master Bedroom Drywall Ceiling 10-14 Y Master Bedroom Drywall South wall 99 Y Master Bathroom Drywall Ceiling 8-11 Y Master Bathroom Wood Vanity cabinet on north wall 7-10 Y Hall Bathroom Wood Vanity cabinet on east wall 10-13 Y Guest Bathroom Wood Vanity cabinet on north wall 10-15 Y Bar Cabinet Drywall Bar sink cabinet 7-15 Y 2.3 Temperature and Relative Humidity The interior conditions of a residence may also play an integral role in the presence of suspect fungal growth. As part of the assessment, RAE collected temperature and relative humidity percentage readings in affected and unaffected areas of the subject property. The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) specifies the combinations of indoor space environment and personal factors that will produce thermal comfort conditions acceptable to 80% or more of the occupants within the space. Specifically, temperatures in the winter should range from 68-74°F and in the summer should range from 73-79°F. The ASHRAE Standard 62.1-2010 and 62.2-2010 suggests that relative humidity levels indoors should be maintained between 30% and 60% for personal comfort and the control of moisture and potential microbial growth. Any levels above 60% may potentially promote fungal growth. The following table summarizes the temperature and relative humidity percentage measurements RAE collected while on site: Rarefied Air Environmental- 9921 Carmel Mountain Road, #164 San Diego, California 92129 Table II: Summary of Temperature & Relative Humidity Readings Location/Room Temperature 0F Acceptable (Y/N) Relative Humidity % Acceptable (Y/N) Outside Conditions: Partly Cloudy 72.3 48.4 Kitchen 75.0 Y 51.6 Y Upstairs Hallway 76.1 Y 58.4 Y The above-referenced temperature and relative humidity % levels were found to be within acceptable ranges. 3.0 AIR FUNGAL SPORE SAMPLING 3.1 Non-Viable Air Sampling Collection & Analysis Methodology RAE collected indoor and outdoor air samples as part of the site assessment. Air samples were collected with the use of a Bioaerosol Sampling Pump. An “Air-O-Cell” cassette is placed in the bioaerosol sampling pump and run at a rate of fifteen (15) liters of air per minute for a set duration of time based upon the environment being assessed. The bioaerosol sampling pumps are calibrated with a rotometer prior to use at the rate of 15 liters per minute. The “Air-O-Cell cassettes are designed to collect a wide variety of airborne particles including but not limited to: fungal spores, pollen, insect parts, skin cell fragments, fibers and other inorganic particles. The “Air-O-Cell” samples are delivered to an independent and accredited laboratory for analysis. The laboratory performs a direct fungal examination of the inner film of the cassette and provides the analytical data included as an attachment to this document. The spore types are listed alphabetically on the analytical results. The “Raw” column indicates approximately how many of that specific spore type that they analyzed on each air sample. They then extrapolate those numbers into a reading of that specific spores per cubic meter of air (spores/m3) for a 2nd column. A 3rd column marked for percentage (%) will indicate approximately what percentage that specific spore type accounts for all the mold spore types indicated. 3.2 Air Fungal Spore Sample Laboratory Results RAE collected a total of three (3) air fungal spore samples as follows: •One (1) inside the Kitchen •One (1) inside the Upstairs Hallway •One (1) outdoor control air sample(s) for comparison purposes There are no established acceptable permissible exposure limits or clearance levels for airborne mold spores. Airborne fungal (mold) spores are ubiquitous in the environment and are found in normal indoor settings. However, indoor fungal (mold) spore samples should be within the same ranges as the outdoor (control) air sample(s). If the indoor mold spore samples are found in excessive amounts, it may be an indication that the property is facilitating microbial growth.

Results are indicative of samples taken at a given time, and may not be representative of other locales and time frames. Heavily loaded samples may have intense occlusion that may pose a bias for quantifying and identifying total spores, as blending of spores and background/debris may occur. Results may be reported as "Present" or "Observed" if quantitative results are not requested or not possible due to overloading or excessive ambiguity among spores and debris. The limit of detection is defined as observing 1 spore, fungal body/mycelial fragment, or pollen grain. The analytical sensitivity for this method is calculated as 1 observation multiplied by (((1000L / volume of air sampled (L)) x 1/m³). Percent trace read and/or sample volume drawn will proportionately affect the reporting limit and/or analytical sensitivity. Calculated data are accurate to two significant figures.
