Assessment activities were completed to locate and screen for possible impacts to the subject property from former historical use of the site. The enclosed report summarizes the results of WithersRavenel’s field activities and presents the findings of assessment of existing environmental conditions at the site. Our findings and general recommendations are summarized below. It is our understanding that resolution of these findings to the satisfaction of the applicable NC regulatory agencies so that any active or future release incident will be closed by the regulatory agency is the responsibility of the seller. 1) Historic petroleum UST release The historical petroleum UST release persists at the site and remains an open incident with NCDEQ. It is our understanding that assessment and remediation of this release is eligible for reimbursement by the NCDEQ Petroleum Commercial UST Cleanup Fund. WR recommends the seller pursue closure of this release incident within the applicable provisions of the risk based rules established by the NCDEQ UST Section. It is our opinion that additional assessment is required to understand the degree and extent of contamination and to develop a plan for remediation of that portion of the contamination above the risk based cleanup levels. Should active remediation be required to satisfy requirements of the UST Section and that active remediation effort involve any type of infrastructure to be installed on the property then such installation should be planned with the engineers involved in site planning and design efforts to ensure that no conflicts arise from any proposed remediation with the future development. Likewise the degree of offsite migration of the contaminant plume as it relates to adjoining properties should be determined and the impacts to those property owners addressed. Risk based corrective action does not mean complete remediation of the site but only lowering concentrations of certain contaminants to levels below established cleanup standards. Our opinion is that any future assessment, remediation and monitoring can be coordinated and accommodate the proposed reuse of the property. WithersRavenel Our People.

WR only completed limited assessment in this area, however, the results show only a low level of contaminants which we do not currently expect that if representative of worst case conditions would warrant active remediation. WR recommends the seller pursue closure of this release incident within the appropriate NCDEQ regulatory agency. It is our opinion that additional assessment is required to understand the extent of contamination and to develop a plan for remediation of that portion of the contamination above the risk based cleanup levels. As the proposed commercial building will be located over the monitoring well location that was reported to contain the chlorinated hydrocarbon impacts it will be important to a future tenant to understand that the chlorinated hydrocarbons have not created a soil vapor plume that could create a source of potential indoor air contamination. Therefore, the assessment of soil vapor will be important for the area surrounding this building and separator location to demonstrate that this is not a concern for the proposed building and that no special construction measures are warranted. 3) Low Level Petroleum Detections in Soil Low level petroleum hydrocarbons were detected in soil at several locations across the site. The hydrocarbon impacts are believed to be associated with the historical dealership operations and specific use of the oil water separators, virgin and waste oil ASTs, air compressors, etc. WR recommends the seller pursue closure of this release incident within the applicable provisions of the risk based rules established by the NCDEQ UST Section. 4) BMW Service Building Low Level Chlorinated Hydrocarbon Detections in Soil Soil was reported by the laboratory to contain several chlorinated hydrocarbon detections for the samples collected from select borings within the BMW service building. WR only completed limited assessment in this area, however, the results show only a low level of contaminants which we do not currently expect that if representative of worst case conditions would warrant active remediation. WR recommends the seller investigate this finding to determine if it is significant and if so pursue closure of this release incident within the appropriate NCDEQ regulatory agency. 5) Vacating the Property and Closure of All Oil-Water Separators, Etc. WR understands that automotive maintenance, repair and service operations will be ongoing for at least 12 months. Removal of all in-ground oil water separators and completion of assessment activities associated with those closures should be completed with documentation of the closure conditions. Any active releases should be investigated and remediation to satisfy the risk based corrective action rules of the appropriate NCDEQ regulatory agency. WithersRavenel Our People.

PURPOSE WithersRavenel has performed a Phase II ESA on a ±12.93-acre site approximately 335 feet to the northeast of the intersection of Old Durham Road and Scarlett Drive (Figure 1). According to Orange County GIS records, the subject property consists of two parcels: Tract # PIN # Current Owner Property Address Acreage Tract 1 9799782859 Hendrick Automotive Group 1806 Fordham Boulevard ±11.64 Tract 2 9799782464 Hendrick Automotive Group 130 Old Durham Road ±1.29 The Phase II ESA was completed to investigate potential sources of contamination including oil water separators, floor drains, and storage areas. Additional activities were also completed to assess the extent of previously identified solvent contamination in soil at the site resulting from historic automotive maintenance activities. 2. PHASE II ENVIRONMENTAL SITE ASSESSMENT ACTIVITIES WithersRavenel conducted Phase II ESA activities from April 18 through April 20, 2016. The following paragraphs describe the results of the investigation. 2.1. UTILITY LOCATION WR mobilized to the subject property with subcontractor, Northstate Utility Locating, Inc., to locate and mark subsurface utilities in the investigation area. WR also notified the North Carolina One Call Center (NC811) for the location and marking of subsurface utilities along the right-of-way on the subject property. A site map depicting current site conditions has been provided as Figure 2. 2.2. SOIL ASSESSMENT WR along with drilling subcontractor Quantex Inc., conducted the subsurface investigation utilizing a 7822DT GeoProbe® drill rig. A continuous sleeve Macro-Core sampler was employed to collect a representative cross-section of geologic material. A WR geologist removed the sample material from the liner and logged the lithology encountered in the borings. Representative soil samples were collected from each soil boring in two foot increments, depending on amount of recovered soil, and were placed in individual zip-lock bags. The retained soil samples were then field screened using a field calibrated MiniRae 3000 Photoionization Detector (PID) for the presence of volatile organic compounds (VOCs). Based on field screening results, WR submitted at least one soil sample from each boring to a mobile laboratory, which analyzed soil samples for petroleum hydrocarbons using UVF technology. Results from the mobile laboratory are included in the Appendix A. WR collected one representative soil sample from each of the twenty-four soil borings and submitted them to a laboratory for analysis by the following analytical methods:  Volatile Organic Compounds (EPA Method 8260); Figure 3 illustrates the location of each soil boring. Boring logs are included in Appendix B. 2.3. SOIL ANALYTICAL RESULTS UVF – TPH The UVF analytical method reported the following detections of TPH-Diesel Range Organics (DRO) above the NCDEQ Action Level of 10 mg/kg: WithersRavenel Our People.

A summary of the UVF analytical method results are presented in Table 1. Figure 3A illustrates the location of each boring and provides a summary of the TPH-GRO and TPH-DRO UVF analytical method results. A copy of the laboratory analytical report and chain-of-custody is included in Appendix A. Volatile Organic Compounds Analytical results identified two soil samples, SB-1 collected between 2.5 and 5 feet below land surface and SB-3 between 2 and 4 feet below land surface, containing benzene concentrations above its NCDEQ Soil-to- Water MSCC of 0.0056 mg/kg. No other compounds were reported to exceed the Soil-to-Water MSCCs from any of the other areas investigated. Several soil samples contained compounds at concentrations above laboratory reporting limits but below Soil-to-Water MSCCs. A summary of the VOCs analytical method results are presented in Table 2. Figure 3B illustrates the location of each boring and provides a summary of all the compounds which were detected above the laboratory reporting limit. A copy of the laboratory analytical report and chain-of-custody is included in Appendix A. 2.4. GROUNDWATER ASSESSMENT ACTIVITIES WR and Quantex, Inc. installed four Type II groundwater monitoring wells (MW-21, MW-22, MW-23, and MW-24) on the subject property. The monitoring wells were installed utilizing a 7822DT GeoProbe® drill rig and solid stem auger drilling methods. Monitoring wells were installed to depths ranging from 21 feet to 29 feet below land surface, based on field observations. The wells were constructed with a 15-20 foot section of 2-inch diameter 0.010-inch slotted Schedule 40 PVC well screen placed at the base of the borehole, followed by Schedule 40 PVC riser to land surface. A sand pack was established around and to 2’ above the screen. A bentonite seal was then placed over the sand pack and hydrated. The remaining annular space was filled with cement grout up to land surface. Boring logs for the monitoring wells are included in Appendix B, and monitoring well construction records are included in Appendix C. The monitoring wells were then developed and purged of water and fine sediment prior to sampling. In addition to the 4 newly-installed monitoring wells, two existing wells (MW-18 and MW-20) were also sampled. Each monitoring well was purged of three well volumes via peristaltic pump equipped with virgin polyethylene tubing. The groundwater samples were submitted for laboratory analysis by the following methods:  Volatile Organic Compounds by EPA Method 8260; 2.5. GROUNDWATER ASSESSMENT LABORATORY RESULTS Laboratory analytical results for the groundwater samples collected from MW-18, MW-20, MW-21, MW- 22, and MW-24 did not identify any analytes at concentrations that exceeded their respective 15A NCAC 2L Standard. Moreover, no analytes were reported at concentrations that exceeded their respective laboratory reporting limits from MW-18 and MW-20. MTBE was detected in MW-21, MW-22, and MW-24 at concentrations above the laboratory reporting limit but below the NCAC 2L standard of 20 µg/L. Two compounds were detected in the sample collected from MW-23 at concentrations above their respective 15A NCAC 2L Standard. 1,1-Dichloroethane was detected at a concentration of 21.7 µg/L, which WithersRavenel Our People. Your Success. Performance Auto Mall Property WithersRavenel Project #02160061.02 Phase II Environmental Site Assessment May 2016 3 exceeds the 2L Standard of 6 µg/L. The 1-1-Dichloroethene concentration of 7.99 µg/L exceeds its 2L Standard of 7 µg/L. Additionally, cis-1,2-Dichloroethene was detected in MW-23 at a concentration of 69.9 µg/L, which is just below the 2L Standard of 70 µg/L. A summary of the laboratory analytical data is included as Table 3. Figure 4 illustrates the location of each monitoring well and provides a summary of all the compounds which were detected above the laboratory reporting limits. The complete laboratory reports and chains-of-custody are included in Appendix A. 3. FINDINGS & CONCLUSIONS WithersRavenel has completed a Phase II Environmental Site Assessment at the ±12.93-acre Performance Auto Mall property. This investigation was initiated following the identification of several RECs through the performance of a Phase I ESA, completed for the subject property in February 2016. Findings of assessment activities conducted at the site by WR during April 2016 included the following: • On-site mobile laboratory testing of soils through UVF analysis indicated the presence of diesel range TPH in samples retained from 19 samples submitted for testing. Diesel range TPH levels reported in five of these samples were in excess of the minimum reportable concentration RC established by NCDEQ-DWM. • Analytical data for fixed-base laboratory analysis of soil samples by EPA Method 8260B indicated one or more targeted compounds in samples retained from borings SB-1, SB-2, SB-3, SB-9, SB-14, SB-16, SB-17, SB-19, SB-20, SB-23, and SB-24. Borings SB-23 and SB-24 were reported to contain low level detections of chlorinated hydrocarbon constituents in soil. • Benzene was detected in samples from SB-1 (located in proximity to the Acura waste storage area) and SB-3 (located in downgradient of the oil water separator adjacent to the Acura service building) were reported at concentrations exceeding their respective Soil to Water MSCCs. • The presence of contaminants in the soils of the site subsurface indicate the presence of releases at the site associated with the onsite oil water separator systems and waste storage adjacent to Acura service, none of which have been assessed to levels equivalent to regulatory standards. • Data for groundwater samples obtained from monitoring wells located on the site indicated the presence of MTBE at concentrations above laboratory detection limits but below the 2L Standard in the samples from MW-21, MW-22, and MW-23, which border the preexisting petroleum containment plume. Results from theses samples further define the petroleum plume to the east and west. • Data for a groundwater sample obtained from monitoring well MW-23, adjacent to the oil water separator at the Acura service building, indicated the presence of several chlorinated solvent compounds. 1,1-Dichloroethane and 1,2-Dichloroethene were detected in MW-23 at concentrations in excess or their respective 2L Standards. Cis-1,2-Dichloroethene was detected in MW-23 at a concentration of 69.9 µg/L, which is just below its 2L Standard of 70 µg/L. • Data for groundwater samples retained from monitoring wells MW-18 and MW-20 did not indicate the presence of compounds at levels above the MDL for EPA Method 8260B. Our general recommendations are summarized below. It is our understanding that resolution of these findings to the satisfaction of the applicable NC regulatory agencies so that any active or future release incident will be closed by the regulatory agency is the responsibility of the seller.
