March 13, 2012 Scott Hill Development Ltd. c/o Mr. Doug Chysik Chysik Project Management Ltd. 15095 Royal Avenue White Rock, BC V4B 1M1 Dear Mr. Chysik: Re: Report of Findings – Phase 2 Environmental Site Assessment

7000 and 6976 Scott Road, Surrey, BC Project No: 11272 This letter report presents the findings of a KEYSTONE ENVIRONMENTALTM Phase 2 Environmental Site Assessment (ESA) prepared at the request of Scott Hill Development for the properties located at 7000 and 6976 Scott Road, in the City of Surrey, BC (the Site). The Site location is shown on Figure 1. It is understood that this Phase 2 ESA will be used for financing purposes.

1. BACKGROUND

Keystone Environmental conducted Phase I Environmental Site Assessment (ESA), at the request of Scott Hill Development. Summary of the areas of potential environmental concern (APECs) identified in the Phase 1 ESA are as follows.

APEC 1 – Potential Heating Oil Tank located at 7000 Scott Road

A single-family residence was located on the northwest corner of the Site from the early 1950s or earlier to the late 1980s. It is unknown how the former Site building was heated prior to the availability to natural gas. It is possible that heating oil could have been used at the Site and was stored in an underground storage tank (UST).

APEC 2 – Service Station located at 11996 70th Avenue

Various service stations have been located at 11996 70th Avenue, approximately 30 m to the west of the Site, since the early 1970s. This property is listed in the MOE Site Registry as 11996 70th Avenue (Site ID: 369). The property was registered in February 1998 and was last updated in September 2006. The Record Status is listed as “Active – Under Assessment.” A notation indicates that a notification about likely or actual substance migration to neighbouring site was initiated in July 2006. During the Site reconnaissance, five monitoring wells were observed on this property and four monitoring wells were observed along 120th Street, approximately 25 m to the west of the Site.

Report of Findings – Phase 2 Environmental Site Assessment

7000 and 6976 Scott Road, Surrey, BC

2 Project 11272 / March 2012

The Keystone Environmental Stage 1 PSI report concluded that further investigation of the APECs was warranted.

The objective of the Keystone Environmental Ltd. (Keystone Environmental) Phase 2 ESA was to investigate groundwater and soil vapour quality in the vicinity of the off-Site service station and perform a field level survey to determine the likelihood of potential on-Site USTs in the vicinity of the former on-Site residence to provide due diligence information. No on-site APECs were identified other than the potential heating oil tank.

2. STUDY LIMITATIONS

Findings presented in this report are based upon the results of this Keystone Environmental Phase 2 ESA that includes field investigations conducted in March 2012 including groundwater and soil vapour sample analyses. Geologic observations and analytical results reflect conditions encountered at a specific test location. Site conditions (geologic, hydrogeologic, and chemical characterization) may vary from that extrapolated from the data collected during this investigation. Consequently, while findings and conclusions documented in this report have been prepared in a manner consistent with that level of care and skill normally exercised by other members of the environmental science and engineering profession practising under similar circumstances in the area at the time of the performance of the work, this report is not intended, nor is it able to provide a totally comprehensive review of present or past site environmental conditions.

This report has been prepared solely for the internal use of Scott Hill Development, pursuant to the agreement between Keystone Environmental Ltd. and Scott Hill Development. A copy of the general terms and conditions associated with this agreement is attached at the end of this report. By using the report, Scott Hill Development agrees that they will review and use the report in its entirety. Any use which other parties make of this report, or any reliance on or decisions made based on it, are the responsibility of such parties. Keystone Environmental Ltd. accepts no responsibility for damages, if any, suffered by other parties as a result of decisions made or actions based on this report.

3. APPLICABLE STANDARDS

The applicable provincial regulations used for comparison of analytical results are contained in the following documents:

Environmental Management Act (EMA), ([SBC 2003], Chapter 53 assented to October 23, 2003)

Contaminated Sites Regulation (CSR) (BC Reg. 375/96 O.C. 1480/96, includes amendments up to B.C. Reg. 286/2010, October 4, 2010)

Hazardous Waste Regulation (HW) (BC Reg. 63/88 O.C. 268/88, including amendments up to B.C. Reg. 63/2009, April 1, 2009)




3.1 Soil Standards

The CSR provides generic and matrix numerical soil standards for different land use categories. The matrix numerical soil standards provide standards for potential contaminants based on several site-specific factors (e.g., intake of contaminated soil, toxicity to soil invertebrates and plants). To determine the appropriate standard for a contaminant, the applicable factors for a site are first selected. The lowest standard of those for applicable factors for the site is then defined as the standard that will apply.

The Site is comprised of two properties (7000 and 6976 Scott Road, Surrey BC) are currently vacant and forested that covers an area of approximately 18,977m2. The current land zoning is residential; therefore the CSR standards for Residential land use (RL) would be applicable to the Site.

3.2 Groundwater Standards

The CSR standards for the protection of aquatic life (AW) apply to groundwater located within 500 m of a surface water body containing freshwater or marine aquatic life. Aquatic life water use also applies at sites where the potential for contaminated groundwater to flow through preferential pathways that discharge to within 500 m of a surface water body containing aquatic life. The closest freshwater surface water body to the Site is an unnamed pond adjacent to Cougar Creek, which is located approximately 140 m southeast of the Site.

Sufficient hydrogeological data has not been compiled for the Site to determine potential preferential pathways between the Site and the nearest water bodies. Based on the distance from the Site to the nearest surface water bodies, the CSR standards for the protection of freshwater aquatic life have been conservatively applied to the Site.

The CSR DW standards are based on current use and protection for the potential future use of drinking water in the area of the Site. The drinking water standards are considered applicable to a site unless the groundwater meets the following conditions:

If groundwater or surface water intake wells are not located at, or within, 100 m up-gradient or 500 m down-gradient of the outer edge of contamination at the site

If a suitable aquifer (hydraulic conductivity greater than 1 x 10-6 m/s and aquifer yield greater than 1.3 L/min) is not located beneath the site

If the natural quality of groundwater in the aquifer is unsuitable for drinking water (total dissolved solids (TDS) are greater than 4,000 mg/L, or is contained within organic soils or muskeg)

If there is a confining geological unit that adequately protects the aquifer (greater than or equal to 5 m thick, bulk hydraulic conductivity less than or equal to 1 x 10-7 m/s, relatively uniform and free of fractures, is continuous across the extent and predicted migration pathway of the shallow subsurface contamination, and the lower 5 m has not been penetrated by contamination from the above units).




The BC Water Resource Atlas, which displays groundwater management information for the Province of BC, shows that water wells are not located within 500 m of the Site. The groundwater in the area of the Site is therefore not currently used for drinking water purposes.

Based on the subsurface conditions observed during drilling at the Site, it is considered likely that the groundwater conditions required to exclude the CSR DW standards, considering the potential future use for drinking water, will not be met. Confining units and organic soil layers were not observed in the geology at the Site. Based on the observed geology, the hydraulic conductivity for the Site is estimated to be approximately 1x10-6 (Freeze and Cherry, 1979). Therefore, to be conservative, the CSR DW standards have been applied to the Site groundwater.

4. INVESTIGATIVE PROGRAM

The Keystone Environmental Phase 2 ESA field work was conducted from March 2 through March 5, 2012. The objective of this Phase 2 ESA was to determine if potential constituents of concern (PCOCs) associated with the APECs identified in the previous Stage 1 PSI completed by Keystone in February 2012 are present in Site groundwater and Soil vapour at concentrations greater than the applicable standards outlined in the CSR.

The following table presents the APECs, the corresponding investigative locations, and the associated potential constituents of concern. The on-Site investigative locations and off-Site APECs are shown on Figure 1.

Documenting the results of the investigation in this letter report

4.1 Electro-Frequency Survey

Prior to the drilling investigation, an underground utility locate was conducted on March 2, 2012. The utility contractor, Helux Environmental Services (Helux), was contracted to identify the potential for underground utilities at the proposed drilling location. The utility contractor determined that utilities were not located within a two metre radius of the proposed borehole location between 7000 and 6976 Scott Road with an electro-frequency survey.

The use of ground penetrating radar at the site was precluded as the dense vegetation and debris was present in the area of the former residence. As a result, an electro-frequency survey was completed in the area of the former residence to search for underground evidence that may be indicative of the presence of USTs.

Subsurface anomalies potentially indicative of USTs were not conclusively identified in the areas surveyed. Based on the redevelopment plans of the Site, it is anticipated that there is a low potential for a heating oil UST to be an area of environmental concern, as the contamination, if any, would likely be isolated based on the geology observed and the contamination would be dealt with during the site preparation phase of the development.

4.2 Borehole Drilling and Soil Sampling

Drilling was performed for the Phase 2 ESA on March 3, 2012 by Blue Max Environmental Drilling Co. Ltd. (Blue Max) of Port Coquitlam, BC. A truck-mounted rig equipped with solid stem augers was used to advance the borehole.

Soil samples were collected directly from the solid stem augers by first removing the outer 10 mm of soil in order to obtain a representative sample. One sample (laboratory sample) was placed in two glass jars (125 mL each) with minimal headspace and sealed. A second sample (field sample) was placed and sealed in a Ziploc® polyethylene bag to an approximate 50% volume for measurement of soil headspace vapours.

Field samples were screened for volatile constituents using a portable photo-ionization detector (MiniRAE). This instrument cannot be used to directly quantify the concentrations of volatile constituents as determined by the laboratory. However, it does provide an indication of volatile compounds and hydrocarbons to assist in sample selection for laboratory analysis. The headspace vapour screening procedure is described as follows:

Field soil samples were allowed to warm for approximately 120 minutes to allow the release of any hydrocarbon vapours into the headspace of the polyethylene bag

Following the one hundred and twenty minute holding period, a hole was punctured into the polyethylene bag using the MiniRAE instrument to obtain the headspace vapour concentration measurements




The soil sample depth intervals, headspace measurements and lithology were recorded on the field monitoring well logs. Soil samples were not submitted for analysis as elevated headspace readings were not observed in the soils and on-Site activities did not warrant soil investigations.

4.3 Monitoring Well Construction and Groundwater Sampling

Monitoring wells MW12-1 was constructed using stem augers since the soil conditions maintained the integrity of the borehole walls while installing the well and annular materials. The placement of monitoring well screen was dependent on the depth of the apparent water table and the potential constituents of concern associated with the off-site service station.

A Schedule 40 PVC screen with 0.25 mm slot width and 3.0 m in length were used during the construction of the monitoring well. Solid PVC riser pipes extended from the top of the 3 m screen to the well head. Filter sand was placed as a filter pack around the well screen and to at least 0.15 m above the top of the screen. To provide a seal above the sand pack and reduce the potential for vertical migration of groundwater or infiltration of surface waters into the well, bentonite chips overlined the sand pack. The monitoring wells were finished with a PVC stick up with a J-plug.

Following construction, the monitoring well was measured for water level and well headspace vapour level. The monitoring well was developed prior to sampling using dedicated WaterraTM tubing, a surge block and a footvalve in order to remove fine-grained sediments from the well and filter pack in preparation for groundwater sampling. The volume of water in the wells was calculated prior to developing, and a minimum of six times the well volume of water was removed or the well was developed dry three consecutive times.

Following well development on March 5th, 2012, purging was conducted on using a peristaltic pump to remove standing water within the well column and enable sampling of representative formation groundwater. Groundwater was monitored for pH, specific conductance, temperature and oxidation-reduction potential (ORP). Well purging was considered complete when the values of pH, specific conductance, temperature and ORP were within 0.1 units, 10%, 1oC and 10 mV of the previous measurements.

The monitoring well was sampled using a peristaltic pump and the low-flow sampling procedure for the analysis of LEPHW, HEPHW, PAH, and dissolved metals. The low-flow sampling procedure was used to minimize the amount of sediment entrained in the water column for sampling. WaterraTM tubing with a footvalve was used to collect samples from the monitoring wells for VOC and VPHw analysis. Groundwater samples were placed in chilled coolers, and were transported to the laboratory (Maxxam Analytics in Burnaby, BC) under standard chain of custody procedures.

4.4 Soil Vapour Well Installation and Soil Vapour

One soil vapour monitoring well (SV12-1) was installed approximately 1 m distance from MW12-1 using soild stem augers. A 150 mm by 6.4 mm soil vapour screen was installed below a bentonite seal and filter sand pack. The soil vapour well screen was positioned within a 0.3 m thick layer of 10/20 filter sand. Nylon tubing was connected to the top of the soil vapour well screen and extended to the surface. Finely ground bentonite powder was placed above the filter




sand and around the nylon tubing, and then hydrated to seal the well screen from external air sources from the ground surface (ambient air) or from soil layers located above the well screen. The nylon tubing was crimped to prevent water and ambient air from entering the tubing prior to sampling. The soil vapour screens were installed at depths of approximately 1.0 mbg for monitoring.

Soil vapour samples were collected on March 5, 2012 using laboratory-supplied pumps to extract soil vapour through thermal desorption tubes. The sampling was conducted at least 48 hours after installation of the soil vapour probes to allow for the vapour within the probe to equilibrate with the vapours in the surrounding soils. Purging of the soil vapour probe and tubing was conducted at each of the locations with approximately one litre of soil vapour expelled.

Leak testing was conducted at each soil vapour well using isopropanol to ensure the integrity of the soil vapour probe from exposure to ambient or other air sources. Samples were collected for analyses of VOCs, VPH, naphthalene and isopropanol, based on the APEC.

The sampling train was connected; and one to three soil vapour well volumes of air were purged to expel non-representative vapour prior to sampling. Purging and sampling was monitored by vacuum and flow testing at soil vapour well. Once purging was completed, vapour samples were drawn by a laboratory-calibrated pump into laboratory-supplied sample tubes. Samples were submitted in thermal desorption sampling tubes under a chain of custody to Maxxam for laboratory analysis of the vapour potential constituent of concern (PCOC).

5. INVESTIGATIVE RESULTS

5.1 Surficial Geology and Field Observations

The soil profile was logged by observation of the soil retrieved from the augers. The soil was classified using the Unified Soil Classification System. Top soil was encountered at the surface of the borehole location. The following is a general description of the stratigraphy encountered beneath the surface at the Site.

Unit A: Top Soil – Organic brown to black top soil with plant roots was present from surface to approximately 0.1 mbg.

Unit B: This unit consists of grey silty clay with minor sand and gravel components. Rootlets were present. The soil was soft, damp to moist, with medium plasticity. Odours or staining were not observed. This unit was encountered near surface and extended to a depth of 2.2 mbg.

Unit C: This unit consists of grey fine sandy and silty clay, with minor orange coloured gravel. The soils were soft, damp to moist, with medium plasticity. Odours or staining were not observed. This unit was encountered below Unit B to a depth of 3.5 mbg

Unit D: This native unit consists of blue-grey clay. The soils were soft and wet, with medium plasticity. Odours or staining were not observed. This unit was encountered below Unit C to the final drilling depth of 3.5 mbg

The soil headspace vapour measurements ranged from 3 parts per million by volume (ppmv) to 7.9 ppmv, and were not consider elevated.




5.2 Hydrogeology and Field Observations

Local groundwater flow direction cannot be determined within the scope of this investigation. Based on elevation contours derived from the Energy, Mines and resources 1:50000 Topographical map, the site groundwater is expected to follow local topography toward the south west toward Cougar Creek.

The depth to groundwater was measured at approximately 0.8m below top casing (TOC) relative to the 0.1 m stick up casing at MW12-1. Well casing headspace vapour measurement was 25 ppm using the GastechTor 1238 ME. This well headspace measurement is not considered elevated.

5.3 Groundwater Analytical Results

A groundwater sample from MW12-1 was collected and submitted to the laboratory for analysis for constituents LEPHw, HEPHw, PAH, VOC, VPHw, and dissolved metals.

The analytical results indicated the concentrations of LEPHw, HEPHw, PAHs, VOC and VPHw were less than the reported laboratory detection limits and therefore less than the CSR AWFW and DW standards for the sample analyzed.

The analytical results indicated the concentrations of dissolved metals were less than the CSR AWFW and DW standards for the sample analyzed.

The groundwater analytical results are presented in Tables 1 to 5, and are summarized on Figure 1. The laboratory analytical results are attached at the end of this report.

5.4 Soil Vapour Analytical Results

The analytical results for vapour are presented in Table 6 and on Figure 1. Laboratory reports are attached in at the end of this report.

The applicable attenuation factors were applied to the Keystone Environmental vapour analytical results to estimate breathing zone concentrations in indoor and outdoor air. The application of attenuation factors is described in the following calculation:

Cindoor air = Cvapour * α

Where:

Cair ( µg/m3) is the estimated indoor or outdoor air concentration of the PCOC

Cvapour is the measured vapour concentration of the PCOC

α is the vapour attenuation factor (Table 1 – BCMOE, 2010)




Attenuation factors are location-specific and dependent on the vapour sample depth. For vapour samples collected at 1.0 mbg, the applicable outdoor attenuation factor is 0.0000015 and the applicable indoor residential attenuation factor is 0.0028. The attenuation factors applied to the measured results are listed in Table 6. The attenuation factors are used to predict concentrations of vapour PCOCs in indoor and outdoor air. Vapour investigation and sampling was conducted in general accordance with Technical Guidance 4 (BCMOE, 2010).

With the exception of benzene, non-attenuated soil vapour concentrations of PCOCs did not exceed the CSR RL standards outlined in Schedule 11. Application of the applicable attenuation factors noted in the Ministry of Environment (MOE) Technical Guidance Document #4 resulted in estimated concentrations of constituents in the predicted indoor and outdoor breathing zones which were also less than their applicable CSR RL standards given the potential future and present Site conditions (Table 6).

6. SUMMARY AND DISCUSSION

Keystone Environmental conducted a Phase 2 ESA in March 2012 for the properties located at 7000 and 6976 Scott Road, Surrey, BC. The Phase 2 ESA was conducted to determine if potential constituents of concern (PCOCs) associated with the APECs identified in the previous Stage 1 PSI are present in Site groundwater and/or vapour at concentrations greater than the applicable standards outlined in the CSR.

Keystone Environmental drilled one borehole and completed the borehole as a monitoring well on the property at 6976 Scott Road, Surrey, BC. During the investigation, sheens, stains and odours were not observed in the soil or groundwater at the Site. The underlying geology at the Site generally consisted of grey silty clay with minor sand and gravel.

APEC 1 – Potential Residential Heating Oil Tank

Ground penetrating radar use on site was not possible due to dense vegetation and debris in the area of the former residence. As a result, an electro-frequency survey was completed in the area of the former residence to search for underground evidence that may be indicative of the presence of USTs.

Subsurface anomalies potentially indicative of USTs were not conclusive identified in the area surveyed. However, based on the redevelopment plans of the Site, there is considered to be a low potential for an heating oil UST to be an area of environmental concern as the contamination, if any, would likely be isolated based on the geology observed and would be dealt with during the site preparation phase of the development.

APEC 2 –Off-Site Service Station at 11996 70th Avenue

Various service stations have been located at 11996 70th Avenue, approximately 30 m to the west of the Site, since the early 1970s. This property is listed in the MOE Site Registry as 11996 70th Avenue (Site ID: 369).

Groundwater analytical results indicated that concentrations of LEPHw, HEPHw, PAHs, VOC and VPHw were less than the reported laboratory detection limits and therefore less than the CSR AWFW and DW standards for the sample analyzed.




The analytical results indicated the concentrations of dissolved metals were less than the CSR AWFW and DW standards for the sample analyzed.

Soil vapour from the newly-installed soil vapour wells were analyzed for VOCs, BTEX, styrene, VPHv, naphthalene and isopropanol on March 5, 2012. The concentrations of predicted indoor soil vapour for benzene at MW12-1 did exceed the CSR RL standards prior to attenuation factors were applied. However, the concentrations of predicted indoor soil vapour PCOCs did not exceed the applicable CSR RL standards after an attenuation factor was applied.

7. CONCLUSIONS

Constituents of concern associated with the off-Site service station was not present in Site groundwater or vapour at concentrations greater than the CSR RL, DW and AW standards in the locations investigated.

The electro-frequency survey was not sufficient to conclude that an underground tank was not present. However it is considered to be a low potential for concern, as the contamination, if present from a residential heating oil tank, would likely be isolated based on the geology observed and would be dealt with during the site preparation during the development of the Site.

We trust this is the information you require at this time. Please contact us should you have any questions.

b. CLIENT agrees to indemnify and hold harmless Keystone (including its officers, directors, employees

and agents) from and against any and all losses, damages, liabilities, claims, suits and the costs and expenses incident thereto (including legal fees and reasonable costs of investigation) which any or all of them may hereafter incur, become responsible for or pay out as a result of death or bodily injuries to any person, destruction or damage to any property, private or public, contamination or adverse effects

2

on the environment or any violation or alleged violation of governmental laws, regulations, or orders, caused by, or arising out of in whole or in part: (i) any negligence or willful misconduct of CLIENT, (ii) any breach of CLIENT of any warranties or other provisions hereunder, (iii) any condition including, but not limited to, contamination existing at the site, or (iv) contamination of other property arising or alleged to arise from or be related to the site provided, however, that such indemnification shall not apply to the extent any losses, damages, liabilities or expenses result from or arise out of: (i) any negligence or willful misconduct of Keystone; or(ii) any breach of Keystone of any warranties hereunder.

7. LIMITATION OF LIABILITY Keystone's total liability, whether arising from or based upon breach of warranty, breach of contract, tort,

including Keystone's negligence, strict liability, indemnity or any other cause of basis whatsoever, is expressly limited to the limits of Keystone's insurance coverage. This provision limiting Keystone's liability shall survive the termination, cancellation or expiration of any contract resulting from this Proposal and the completion of services thereunder. After three (3) years of completion of Keystone's services, any legal costs arising to defend third party claims made against Keystone in connection with the project defined in the Proposal or Agreement will be paid in full by the CLIENT.

8. INSURANCE Keystone, during performance of this Agreement, will at its own expense carry Worker's Compensation

Insurance within limits required by law; Comprehensive General Liability Insurance for bodily injury and for property damage; Professional Liability Insurance for errors omissions and negligence; and Comprehensive Automobile Liability Insurance for bodily injury and property damage. At CLIENT'S request, Keystone shall provide a Certificate of Insurance demonstrating Keystone's compliance with this section. Such Certificate of Insurance shall provide that said insurance shall not be cancelled or materially altered until at least ten (10) days after written notice to CLIENT.

9. CONFIDENTIALITY Each party shall retain as confidential all information and data furnished to it by the other party which relate

to the other party's technologies, formulae, procedures, processes, methods, trade secrets, ideas, improvements, inventions and/or computer programs, which are designated in writing by such other party as confidential at the time of transmission and are obtained or acquired by the receiving party in connection with work or services performed subject to this Proposal or Agreement, and shall not disclose such information to any third party.

However, nothing herein is meant to prevent nor shall it be interpreted as preventing either Keystone or

CLIENT from disclosing and/or using said information or data; (i) when the information or data is actually known to the receiving party before being obtained or derived from the transmitting party; or (ii) when the information or data is generally available to the public without the receiving party's fault; or (iii) where the information or data is obtained or acquired in good faith at any time by the receiving party from a third party who has the right to disclose such information or data; or (iv) where a written release is obtained by the receiving party from the transmitting party; or (v) as required by law.

10. PROTECTION OF INFORMATION Keystone specifically disclaims any warranties expressed or implied and does not make any representations

regarding whether any information associated with conducting the work, including the report, can be protected from disclosure in responses to a request by a federal, provincial or local government agency, or in response to discovery or other legal process during the course of any litigation involving Keystone or CLIENT. Should Keystone receive such request from a third party, it will immediately advise CLIENT.

11. FORCE MAJEURE Neither party shall be responsible or liable to the other for default or delay in the performance of any of its

obligations hereunder (other than the payment of money for services already rendered) caused in whole or in part by strikes or other labour difficulties or disputes; governmental orders or regulations; war, riot, fire, explosion; acts of God; acts of omissions of the other party; any other like causes; or any other unlike causes which are beyond the reasonable control of the respective party.

In the event of delay in performance due to any such cause, the time for completion will be extended by a

period of time reasonably necessary to overcome the effect of the delay. The party so prevented from complying shall within a reasonable time of its knowledge of the disability advise the other party of the effective cause, the performance suspended or affected and the anticipated length of time during which performance will be prevented or delayed and shall make all reasonable efforts to remove such disability as soon as possible, except for labour disputes, which shall be solely within said party's discretion. The party prevented from complying shall advise the other party when the cause of the delay or default has ended, the number of days which will be reasonably required to compensate for the period of suspension and the date

3

when performance will be resumed. Any additional costs or expense accruing or arising from the delaying event shall be solely for the account of the CLIENT.

12. NOTICE Any notice, communication, or statement required or permitted to be given hereunder shall be in writing and

deemed to have been sufficiently given when delivered in person or sent by facsimile, wire, or certified mail, return receipt requested, postage prepaid, to the address of the party set forth below, or to such address for either party as the party may be written notice designate.

13. ASSIGNMENT/SUBCONTRACT Neither party hereto shall assign this Agreement or any part thereof or any interest therein without the prior

written approval of the other party hereto except as herein otherwise provided. Keystone shall not subcontract the performance of any work hereunder without the written approval of CLIENT. Subject to the foregoing limitation, the Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of the parties hereto.

14. ESTIMATES To the extent the work requires Keystone to prepare opinions of probable cost, for example, opinions of

probable cost for the cost of construction, such opinions shall be prepared in accordance with generally accepted engineering practice and procedure. However, Keystone has no control over construction costs, competitive bidding and market conditions, costs of financing, acquisition of land or rights-of-way and Keystone does not guarantee the accuracy of such opinion of probable cost as compared to actual costs or contractor's bid.

15. DELAYED AGREEMENTS AND OBLIGATIONS The performance by Keystone of its obligations under this Agreement depends upon the CLIENT performing

its obligations in a timely manner and cooperating with Keystone to the extent reasonably required for completion of the Work. Delays by CLIENT in providing information or approvals or performing its obligations set forth in this Agreement may result in an appropriate adjustment of contract price and schedule.

16. CONSTRUCTION PHASE To the extent the work is related to or shall be followed by construction work not performed by Keystone,

Keystone shall not be responsible during the construction phase for the construction means, methods, techniques, sequences or procedures of construction contractors, or the safety precautions and programs incident thereto, and shall not be responsible for the construction contractor's failure to perform the work in accordance with the contract documents. Keystone will not direct, supervise or control the work of the CLIENT'S contractors or the CLIENT'S subcontractors.

17. DOCUMENTATION, RECORDS, AUDIT Keystone when requested by CLIENT, shall provide CLIENT with copies of all documents relating to the
