2 February 17, 2011 Mr. Patrick Corsinita Aurora Bank, FSB Commercentre Drive, Suite 150 Lake Forest, California Subject: Phase II Subsurface Investigation Park Manor R.V. Manufacturing 8800 East Farm to Market Road 916 Grandview, Johnson County, Texas AEI Project No Dear Mr. Corsinita: AEI Consultants (AEI) is pleased to provide you with the following report which describes the activities and results of the Phase II Subsurface Investigation (Phase II) performed at the above referenced property (Figure 1: Site Location Map). This investigation was completed in accordance with our signed proposal dated January 21, 2010, which included the completion of a ground penetrating radar (GPR) survey as well as the installation of two soil borings to facilitate the collection of soil and/or groundwater samples from beneath the site. A total of two soil samples and one groundwater sample were collected during this limited assessment. Please refer to Figure 2: Site Plan/Sampling Locations for a plan that identifies the locations of the soil borings installed during this assessment. I Site Description The subject property is located on the southwest corner of Farm to Market Road 916 and Farm to Market Road 4 in a mixed commercial, light industrial and residential area of Grandview, Texas. The property totals approximately acres and is improved with three (3) onestory buildings totaling approximately 144,500 square feet. The office and main production building (Building 1), approximately 82,000 square feet, parallels Farm to Market Road 4. The storage warehouse (Building 2), approximately 45,000 square feet, parallels Farm to Market Road 916. The Fluids Management material storage building (Building 3), approximately 17,500 square feet is located adjacent to the south of Building 2. In addition to the three buildings, a mud plant owned and operated by Fluids Management, is located on the northwest corner of the subject property. Fluids Management currently leases this area and Building 3 from the subject property owner. The production of drilling mud is currently the only active operation that occurs on the subject property. Equipment and materials associated with Park Manor RV Manufacturing are stored in Building 1 and Building 2; however, this company is no longer in operation. In addition to the subject property buildings, the property is improved with asphaltpaved and gravel parking areas and associated landscaping. Project No February 17, 2011 Page 2

3 II Previous Investigations AEI completed a Phase I ESA on the subject property in November 2010 (AEI Project No ). Based on a review of historical sources conducted as part of the Phase I ESA, an underground storage tank (UST) was historically utilized on this property by Transcoach, Inc., dba Good Times Van during their time occupying the site. Based on owner interviews and database information reviewed as part of the Phase I ESA, a 10,000-gallon steel gasoline tank was installed on the subject property on January 1, 1983 and was removed from the ground on January 27, No further information was readily available that would suggest if closure sampling was conducted. Although not confirmed by AEI, it was inferred that the UST was used for the purposes of fleet refueling during Good Times Van s occupancy of the site. In addition, the subject property was also identified in the regulatory database as RCRA SQG and RCRA NLR site. Hazardous chemicals associated with the SQG listing include spent halogenated solvents used in degreasing, spent non-halogenated solvents, and spent halogenated solvents. Four violations were reported at this facility in the years 1983 and 1987 and each violation was identified as resolved. The status is reported as inactive. Based on the nature of the violations and identified resolutions, and the inactive status, this listing is not expected to represent a significant environmental concern. However, based on the duration of gasoline storage and fueling on-site (11 years), the lack of any confirmatory or closure sampling of the UST, and the identified responsible party no longer present on the subject property, AEI was unable to rule out the potential that the subject property has been adversely impacted from the historical UST and associated operations. Based on this notion, AEI recommended a comprehensive file review from the TCEQ Central Records Division be conducted in order to verify all proper UST and closure requirements were achieved for the subject property in In the event no sampling or closure investigation was conducted, a subsurface investigation would be warranted. III Investigative Efforts Pre-Drilling Activities On February 2, 2011, AEI contacted Texas One Call (TOC) at to identify any public utilities that may adversely impact the proposed subsurface investigation work proposed during this assessment. The TOC assigned a utility locate clearance number of Ground Penetrating Radar Survey AEI contracted with Ground Penetrating Radar Systems (GPRS) to perform a GPR survey of the subject property. The purpose of this survey was to identify the location of the former UST that was reportedly removed from this site in Based on conversations with the site contact about the location of this former UST, the survey focused on the area between the main entrance gate and the large site building located on the northern property boundary. Utilizing ground penetrating radar (GPR), GPRS was able to locate an excavated area in the general location of the reported former USTs (west of the guard shack and east of the Project No February 17, 2011 Page 3

4 northern-most site building) with possible debris resembling reinforcing steel that was mixed into the backfilled area. No large mass findings of an underground storage tank were found in the inquired area. A copy of the GPRS report is presented as Appendix A. Drilling and Soil Sample Collection Two direct push soil borings were installed at this site during this limited assessment. Soil boring PM-1 was installed on the southern end of the excavated area identified by the GPR survey on the northern portion of the site. Soil boring PM-2 was installed on the northern end of the excavated area identified by the GPR survey on the northern portion of the site. During the installation of the borings, soil samples were collected continuously from land surface to the point of probe refusal encountered at depths of 18 (PM-1) and 20 (PM-2) feet below land surface (bls). Each of the collected soil samples were logged for lithologic characteristics, observed for visual signs of staining and screened for organic vapors with a PhotoVac 2020 photoionization detector (PID). The subsurface soils encountered during this assessment consisted of a tan to brown to dark brown sand, silt and clay of varying amounts. Soil samples were collected from each of the soil borings installed during this assessment as summarized in Table 1: Boring Number Sample Depths (feet bls) Table 1 Soil Sampling Summary Table Justification for Sampling PM Elevated PID reading of 8.6 ppm PM Elevated PID reading of 10.0 ppm TPH = Total Petroleum Hydrocarbons VOCs = Volatile Organic Compounds PAHs = Polynuclear Aromatic Hydrocarbons Analytical Methods VOCs by 8260 PAHs by 8270 (Hold) TPH by TX1005 VOCs by 8260 PAHs by 8270 (Hold) TPH by TX1005 Please refer to Figure 2: Site Plan/Sampling Locations for a figure that outlines the site features and the borings installed during this assessment. The boring logs included as Attachment B provide details on the soils observed, the collected PID readings, the samples submitted for laboratory analysis, and other pertinent field notes collected during the field investigation. Groundwater Sample Collection A 1-inch temporary PVC monitoring well was installed to a depth of 18 feet bls in soil boring PM-1. Groundwater was collected from this temporary well utilizing a peristaltic pump and clean disposable tubing. The groundwater sample collected from PM-1 is summarized in Table 2: Project No February 17, 2011 Page 4

Upon completion of the soil sampling at this site, the borings were abandoned in accordance with the State of Texas requirements. Laboratory Analysis The soil samples collected from this site were submitted to TestAmerica Laboratories, Inc. (TAL) of Pensacola, Florida. Analytical results and chain of custody documents are included as Appendix C. IV Findings VOC Soils The volatile organic compound (VOC) acetone by EPA method 8260 was identified in the soil sample collected from boring PM-1 at a concentration of milligrams per kilogram (mg/kg). This concentration of acetone did not exceed its respective Texas Commission on Environmental Quality (TCEQ) comparison level. No other VOCs were identified in the soil samples collected from this site. The acetone identified in the soil sample PM-1 (9 to 10 feet bls) is summarized in Table 3.

6 TPH Soils Total petroleum hydrocarbons (TPH) in the C12-C28 range analyzed by Texas method 1005 (TX1005) were not identified in either of the soil samples collected from this site. PAHs Soils Soil samples collected for polynuclear aromatic hydrocarbon (PAH) analysis by EPA method 8270 were collected and placed on hold at the analyzing laboratory pending the results of the TPH analysis. Since TPH concentrations were not identified in excess of the C12 range, the PAH samples collected and placed on hold at the analyzing laboratory were not analyzed. VOCs Groundwater The VOCs acetone, ethylbenzene, isopropylbenzene, naphthalene, n-propylbenzene, 1,2,4- trimethylbenzene and 1,3,5-trimethylbenzene by EPA method 8260 were identified in the groundwater sample collected from boring PM-1 (PM-1-W) at concentrations ranging from 1.3 micrograms per liter (µg/l) to 19 µ/l. None of the VOCs identified in this groundwater sample exceeded their respective comparison levels. No other VOCs were identified in this groundwater sample. The VOCs identified in the groundwater sample collected from this site are summarized in Table 4.

7 excess of the C12 range, the PAH groundwater sample collected and placed on hold at the analyzing laboratory was not analyzed. V Summary and Conclusions AEI has completed a Phase II Subsurface Investigation at the subject property to evaluate whether a historical petroleum underground storage tank has adversely impacted the soil and groundwater beneath the site. Based on the results of this investigation, it does not appear that the subsurface soil or groundwater beneath the subject property has been impacted above the TCEQ comparison levels. However, the mere presence of impacts above the method quantitation limits (MQLs) warrants additional regulatory investigation and/or corrective action work to be completed. As indicated in TCEQ Publication RG-411 (April 2010), when COCs are present above the higher of MQLs or background, the responsible party must submit a Release Determination Report to the TCEQ to document the findings.

15 1. Overview of GPR Ground Penetrating Radar (GPR) is a non-destructive testing technology that sends a series of radar pulses into the surface which reflect back off of anomalies below. As the radar pulses pass through the ground, the waves bend slightly when encountering a material with differing physical properties, particularly density and conductivity. Thousands of pulses are sent and received in a small area, and the received signals are combined to form a real-time image of what is in the ground. The various places where the radar waves bend are displayed as anomalies which can be interpreted as steel pipes, PVC conduits, underground storage tanks, voids, foundations, etc. One of the many advantages of the technology is the ability to locate non-metallic objects as well as determining depth to the object. GPR data acquisition is very fast and results are available immediately, allowing any discovered anomalies to be marked directly in the field. Although sometimes confused with X-Ray, GPR uses no radiation emissions and is perfectly safe to work with human presence in close proximity.

16 2. Equipment and Capabilities Ground Penetrating Radar (GPR) GSSI SIR 3000 o GPRS uses a Geophysical Survey Systems Inc (GSSI) SIR Radar unit. This is the most advanced GPR available. It allows for onsite interpretation, as well as stores data for later processing. This equipment is self-calibrating, allowing more precise depth and location measurements. o GSSI is the world s leading GPR designer and manufacturer. Information can be found at MHz GSSI antenna o For portions of this project involving concrete scanning, we used a 1600 MHz antenna with the GPR. This antenna allows data collection to a maximum depth of approximately eighteen to twenty-four inches, depending on the condition of the concrete. 400 MHz GSSI antenna o For this project, we used a 400 MHz antenna with the GPR. This antenna allows data collection to a maximum depth of approximately eight feet, depending on soil conditions. RD 7000 Radiofrequency Detection System o This system detects electromagnetic fields, and allows for two methods of onsite utility location. A passive power scan mode detects live currents from electrical conduits. An active frequency scan mode allows tracer signals of various frequencies to be sent along any metallic pipe (or tracer wire) which can be accessed. This system enables utilities to be marked in the field, but records no data. Radan 6.6 software o Radan is the software produced by GSSI for processing all types of radar files. Version 6.6 is the most recent and up to date version available. Glenn Zebrowski Houston, TX fax glenn.zebrowski@gp-radar.com

17 3. Site Description At this site we scanned near the front entrance off of FM 916 next to the main building, roughly 50 x 150 area. GPRS scanned to verify that the underground storage tanks that were previously located at this address had been removed. The area scanned was as directed by Jim Cole and all findings were marked on the surface with paint. Date of Scan: Monday, February 7, Inspection Methods The primary purpose of scanning this area was to locate any underground storage tanks and utilities. To locate the underground storage tanks and utilities we used a 400MHz antenna and we verified power/communication utilities with our Radio Detection. 5. Findings Using the 400MHz antenna I was able to determine that there were no large mass findings of an underground storage tank at the inquired area. We did see other findings in the area that seem to be reinforcing steel that was mixed into the backfilled area. We than cleared several areas around the backfilled area for the drilling and testing to take place. Glenn Zebrowski Houston, TX fax glenn.zebrowski@gp-radar.com

20 7. Qualifications Ground Penetrating Radar Systems, Inc. (GPRS) was started in October 2001, by Matt Aston. The original intention in starting this business was to give contractors a reliable way to see into concrete slabs in order to avoid cutting embedded electrical conduits and critical reinforcing steel. While GPRS performs this work on a regular basis, there are many other applications in which we use Ground Penetrating Radar to benefit our customer base. Since our inception, GPRS has completed over four thousand jobs. We are very proud of our performance. We have had a reported incident of error on less than one percent of the projects we have completed. Our customers have expressed a high level of satisfaction, as evidenced by the fact that in 2009, nearly 75% of our business was either repeat or referred by our customers. GPRS has been involved on projects ranging from small residential jobs to major construction projects with values in excess of $1 Billion.
