Signature-SY111201 (2) PROJECT NO. 17792.1 DECEMBER 2011 LIMITED SUBSURFACE INVESTIGATION PROPOSED SENIOR LIVING FACILITY SANDY LAKE ROAD AT RIVERVIEW DRIVE COPPELL, TEXAS Presented To: SIGNATURE ASSISTED LIVING, LLC HEALTH CARE REIT, INC. HCRI TEXAS PROPERTIES, LTD. C/O SDR DEVELOPMENT, INC. SARASOTA, FLORIDA December 28, 2011 Project No. 17792.1 Signature Assisted Living, LLC Health Care REIT, Inc. HCRI Texas Properties, Ltd. c/o SDR Development, Inc. nd 1800 2 Street, Suite 717 Sarasota, Florida 34236 ATTN: Mr. Pete Russell RE: Limited Subsurface Investigation Proposed Senior Living Facility Sandy Lake Road at Riverview Drive Coppell, Texas Dear Mr. Russell: Reed Engineering Group, Ltd. (Reed) has performed a Limited Subsurface Investigation (LSI) at the above-referenced property in accordance with the scope of work that was authorized by SDR Development, Inc. on November 17, 2011. The proposed scope of work was based on the findings of a Phase I Environmental Site Assessment (ESA) completed by Reed in November 2011. Purpose and Scope The results of Reed’s Phase I ESA identified recognized environmental conditions associated with: the indicated presence of a Closed Landfill Inventory site adjacent to or on the subject property with the potential to have affected the subject property; and undocumented fill placed throughout the property during apparent mining operations and subsequent filling activities. Based on these findings, Reed prepared a scope of work consisting of the installation of test pits to observed for the presence of fill material. Additionally, Reed proposed the installation of five borings/groundwater monitor wells to assess soil and groundwater conditions across the site. The scope of this LSI is limited and was intended to assess if impact to soil and/or groundwater has occurred in selected, representative areas and to observe for fill material in selected areas considered to be representative of the site as a whole. This investigation was not designed to delineate the lateral or vertical extent of contamination, if encountered, and should not be construed as a comprehensive assessment of the site. 2424 STUTZ DR. SUITE 400 DALLAS, TX 75235 [214] 350 5600 [214] 350 0019 TELFAX SDR Development, Inc. Proposed Senior Living Facility Project No. 17792.1 December 28, 2011 Page 2 of 7 Field Activities Test Pits Reed performed oversight of test pit installation on November 22, 2011. Sunbelt Industrial Services was subcontracted by Reed to dig pits using a tracked excavator (Kobelco SK 135 SR) equipped with a two-foot wide bucket. Test pits typically averaged two to three feet in width, 10 to 12 feet in length, and 10 to 16 feet in depth below ground surface (bgs). A total of 16 test pits were installed across the subject property. Locations of test pits are depicted on Figure 1 Illustration inthesection of the report. Reed observed the excavation of each test pit. Reed observed the presence of fill soil at each location at depths ranging from ground surface down to 3 to 6 feet. In the northeastern-most portion of the site (TP-14), fill was encountered at depths down to approximately 12 feet bgs. Fill soils were observed to be underlain by clayey sand or sandy clay soils, followed by clayey soil. Fill soil appeared to consistently be comprised of sandy and silty clays. Additionally, small quantities of limestone fragments were often observed in the fill soil. Reed also observed several limestone boulders, occasional bricks, limited quantities of asphalt (at one location), a metal fence post, a metal sign, a metal cable, and a metal pipe fragment. Observed materials appeared to be considerably less than one percent of fill observed and were noted to be materials that are typically chemically inert. No obvious visual indication of chemical impact was observed during field activities. No odors suggestive of potential impact were noted. No volatile vapors were detected during field screening as read by a flame ionization detector (FID). Given the absence of field indicators of impact, no soil was collected for analyses. Upon completion of observation activities, each pit was backfilled with excavated soil. Field notes describing general observations at each test pit, FID screening intervals/readings, Test Pit Log and other recorded information is including in the section of the report. Boring/Monitoring Well Installation Reed performed drilling activities on December 1 and 2, 2011. This portion of the LSI consisted of drilling and collecting soil samples from five borings. The borings were subsequently converted to permanent monitor wells following completion. Boring locations Illustrations are illustrated in Figure 1 in the section of this Report. Borings were drilled by Reed utilizing a truck-mounted conventional auger rotary drill rig equipped with 5.75-inch flight augers. Augers, barrels, drilling equipment and sampling tools used during field operations were decontaminated using a hot water power washer or an Alconox-water solution and potable water rinse prior to and between each use. Soil samples SDR Development, Inc. Proposed Senior Living Facility Project No. 17792.1 December 28, 2011 Page 3 of 7 were collected in 2-foot Shelby tubes. The sampling tubes were advanced ahead of the augers to collect undisturbed soil samples. The soil samples were then field extruded from the sampling tubes. Selected soil samples from the fill soil interval were placed in pre-cleaned glass jars sealed o with Teflon-lined screw-on lids and placed on ice in a cooler to maintain a 4C holding temperature. Another portion of each sample and deeper soil samples were placed in a zipper- type plastic bag, sealed, and left in the ambient environment to allow volatile vapors to accumulate in the bag. These samples were later analyzed for headspace gases with a flame- ionization detection (FID) meter as a field-screening procedure to aid in sample selection for subsequent chemical analyses. No detections were indicated during field screening activities. Borings were advanced into the uppermost groundwater bearing unit. MW-1 and MW-2 were completed at depths of 20 feet bgs and MW-5 at 25 feet bgs. MW-3 and MW-4 were completed at depths of 40 feet bgs due to an absence of groundwater upon completion of the borings. The monitor wells installed as part of this investigation were constructed by placing the casing into the previously drilled open borehole. Individual lengths of screen and casing were flush- threaded so that no glues or solvents were necessary to join the sections. Each well was constructed with 10 feet of casing and screen comprising the balance of the well. All casing materials were factory pre-cleaned, plastic wrapped, and boxed to ensure that no oils, grease, or other contaminants were present at the time of well construction. Casing material consisted of 2-inch diameter, Schedule 40 PVC pipe and factory-slotted casing with 0.010-inch widths. The filter pack, consisting of clean 10-20 sand, was installed within the annular space from the total depth of the well to approximately two feet above the top of the screened interval. The annular space above the filter pack was sealed with hydrated bentonite to within inches of the ground surface. Groundwater monitor wells were initially developed to remove stagnant groundwater and silts and other materials introducing during drilling activities. Groundwater was collected using a peristaltic pump equipped with new polyethylene tubing changed/discarded between wells. Groundwater samples were transferred to clean appropriate containers. The samples were o properly labeled, entered into the Chain-of-Custody form, and maintained at 4C for delivery to the analytical laboratory. The environmental technician conducting the sampling wore 100% Nitrile gloves, which were changed prior to sampling each well. Physical Setting Based on a review of geologic literature and experience in the area, the site is situated on Quaternary-age alluvium overlying shale of the Cretaceous-age Eagle Ford Formation. The alluvium is associated with floodplain deposition by Denton Creek and the Elm Fork Trinity SDR Development, Inc. Proposed Senior Living Facility Project No. 17792.1 December 28, 2011 Page 4 of 7 River in the geologic past. The alluvial soils typically consist of high plasticity clays grading with depth into sandy clays and clayey sands. The Eagle Ford shale is expected to be approximately 100 feet thick in the site vicinity. Observations made during this LSI appear indicated shallow alluvial soil overlying residual soil of the underlying weathered Eagle Ford shale which was encountered in some areas at depths greater than 30 feet bgs. Static groundwater observed at the site during the duration of this investigation was noted a depths ranging between 10 to 20 feet bgs. The groundwater flow direction and gradient are anticipated to mimic surface topography and be toward Denton Creek. Laboratory Methods Xenco Laboratories in Dallas, Texas, analyzed each of the soil and groundwater samples. The analyses were performed according to U.S. Environmental Protection Agency (EPA) and Texas Commission on Environmental Quality (TCEQ) methods. Soil samples were initially analyzed for TPH, VOCs, and metals. Based on a TPH detection in one soil sample, a polynuclear aromatic hydrocarbons (PAHs) analysis was performed. Groundwater samples were analyzed for total petroleum hydrocarbons (TPHs), volatile organic compounds (VOCs), and metals. One sample from each soil boring was submitted for analyses. Samples were collected from the interval of fill. Groundwater was collected at each well location and analyzed. Analytical Results Soil Analytical Results TPH concentrations for each soil sample were reported below laboratory detection limits with the exception of sample MW-5 3-5’. MW-5 3-5’ was reported with the detectable presence of TPH (C6-C12) in soil at a concentration of 472 mg/kg, TPH (C12-C28) at a concentration of 422 mg/kg, and TPH (C28-C35) at 73.5 mg/kg compared to the applicable Texas Risk Reduction Program (TRRP) Tier 1 Protective Concentration Levels (PCLs) for Residential Soil GW Protective of Groundwater Ingestion (Soil) of Class 1 or 2 Groundwater of 65 mg/kg, 198 Ing mg/kg, and 198 mg/kg, respectively. TPH (C28-C35) was noted to be below the applicable PCL. Given the PCL exceedances of TPH ranges C6-C12 and C12-C28, Reed release additional soil from sample MW-5 3-5’ for PAHs analysis for further environmental screening. PAH analysis for this sample indicated concentrations below laboratory detection limits. Based on no detections of PAH constituents above laboratory detection limits, together with VOC analysis for this sample (discussed below) which indicate VOC constituents below applicable PCLs, TPH range exceedances at MW-5 3-5’ are not considered to present a concern to the subject property. SDR Development, Inc. Proposed Senior Living Facility Project No. 17792.1 December 28, 2011 Page 5 of 7 VOC concentrations for each soil sample were reported below laboratory detection limits with the exception of MW-4 3-5’ and MW-5 3-5’. Detections of methylene chloride, tetrachloroethylene, and toluene were reported in sample MW-4 3-5’. Detections of cis-1,2- dichloroethylene, ethylbenzene, naphthalene, methylene chloride, n-propylbenzene, tetrachloroethylene, toluene, 1,2,4-trimethylbenzene, o-xylene, and m,p-xylene were reported in sample MW-5 3-5’. Based on review of quality control documentation, Methylene chloride was indicated to be a laboratory contaminant. VOC constituents listed above from samples GW MW-4 3-5’ and MW-5 3-5’ were noted to be less than applicable SoilPCLs. Ing Metals analysis indicated the detectable presence of metal concentrations in each of the samples. The metals arsenic, barium, cadmium, chromium, lead, mercury detected across the GW site were noted to be below applicable SoilPCLs and/or Texas-specific soil background Ing concentrations. Selenium, detected in sample MW-5 3-5’ was reported at a concentration of 2.64 mg/kg, exceeding its respective PCL and background concentration of 2.3 mg/kg and 0.3 mg/kg, respectively. The detectable presence of selenium appears to be associated with TPH and VOC contaminants (discussed above) in this sample. Given that no detection of selenium was reported in groundwater from this bore/well location (discussed below), it appears that selenium, that was noted to slightly exceed its PCL, has not affected underlying groundwater. Tables A tabular summary of detected soil constituents is included as Table 1 in the section of this report. Groundwater Analytical Results TPH was not detected above laboratory detection limits in groundwater samples collected from each of the five monitor wells. VOCs were not detected above laboratory detection limits in samples collected from monitor wells with the exception of MW-3, reported with VOC constituents: methyl chloride, ethylbenzene, and methylene chloride. Methylene chloride was the only constituent noted to GW exceed its respective TRRP Tier 1 PCL protective of groundwater ingestion (GW) of ING Class 1 or 2 Groundwater. However, the methylene chloride in this sample was flagged by the laboratory as a probable laboratory contaminant. Based on the common presence of methylene chloride as a laboratory contaminant, this concentration exceedance is not considered representative of site conditions and does not present a concern to the subject property. Metals analysis indicated the detectable presence of metal concentrations in each of the samples. The metals arsenic, barium, chromium, lead, and silver detected across the site were GW noted to be below applicable GWPCLs. ING Tables A tabular summary of detected constituents in groundwater is included as Table 2 in the section of this report. SDR Development, Inc. Proposed Senior Living Facility Project No. 17792.1 December 28, 2011 Page 6 of 7 Conclusions Reed observed the presence of fill soil in each test pit location at depths ranging from the ground surface down to 3 to 6 feet. In the northeastern-most portion of the site (TP-14), fill was encountered at depths down to approximately 12 feet. The material presence of non-soil fill material, debris, and/or waste was not observed during the installation of test pits across the site. Small quantities of limestone fragments were often observed in fill soil. Reed observed limestone boulders, occasion bricks, limited quantities of asphalt, a metal fence post, a metal sign, a metal cable, and a metal pipe fragment. Observed materials appeared to be considerably less than one percent of fill observed and noted to be materials that are typically chemically inert. Field indicators of obvious chemical impact were not indicated during test pit installation activities at the site. Results of the soil sample analyses indicate that, within the areas investigated, shallow soils at MW-4 and MW-5 are impacted with TPH range compounds and/or VOCs. Contaminants were noted with concentrations below applicable comparison criteria with the exception of TPH exceedances at MW-5. However, based on no detections of PAH constituents above laboratory detection limits, together with detected VOCs at this location with concentrations below applicable comparisons criteria, TPH range exceedances at MW-5 3-5’ are not considered to present a concern to the subject property. Further, selenium detected in sample MW-5 3-5’ was reported at a concentration of 2.64 mg/kg, exceeding its respective PCL and background concentration of 2.3 mg/kg and 0.3 mg/kg, respectively. The detectable presence of selenium appears to be associated with TPH and VOC contaminants in this sample. Given that no detection of selenium was reported in groundwater from this bore/well location, it appears that selenium, that was noted to slightly exceed its PCL, has not affected underlying groundwater. Results of groundwater analyses indicate that, within the areas investigated, groundwater has been impacted by VOC constituents at MW-3 at concentrations below applicable TRRP Tier 1 GW GW PCLs with the exception of methylene chloride. Based on the common presence of ING methylene chloride as a laboratory contaminant and its presence in method blanks indicated by the laboratory, this concentration exceedance is not considered representative of site conditions and does not present a concern to the subject property. Metals detected in groundwater are below applicable PCLs. SDR Development, Inc.

MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD. B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference. Dilution factors are included in the final results. The result is from a diluted sample. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the quantiation limit and above the detection limit. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting. K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated numerical value may not be consistent with the amount actually present in the environmental sample. * Surrogate recovered outside laboratory control limit.

P = Samples analyzed within the recommended holding time. Page 30 of 68 Final Flagging Criteria X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD. B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference. Dilution factors are included in the final results. The result is from a diluted sample. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the quantiation limit and above the detection limit. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting. K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated numerical value may not be consistent with the amount actually present in the environmental sample. * Surrogate recovered outside laboratory control limit.

Flagging Criteria X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD. B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference. Dilution factors are included in the final results. The result is from a diluted sample. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the quantiation limit and above the detection limit. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting. K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated numerical value may not be consistent with the amount actually present in the environmental sample. * Surrogate recovered outside laboratory control limit.

P = Samples analyzed within the recommended holding time. Page 15 of 34 Final Flagging Criteria X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD. B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference. Dilution factors are included in the final results. The result is from a diluted sample. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the quantiation limit and above the detection limit. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting. K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated numerical value may not be consistent with the amount actually present in the environmental sample. * Surrogate recovered outside laboratory control limit.

P = Samples analyzed within the recommended holding time. Page 14 of 32 Final Flagging Criteria X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD. B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference. Dilution factors are included in the final results. The result is from a diluted sample. E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the quantiation limit and above the detection limit. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting. K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated numerical value may not be consistent with the amount actually present in the environmental sample. * Surrogate recovered outside laboratory control limit.
