Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Matt Braun of Mangan Inc, a Field Evaluation project was initiated A Final evaluation was completed at: • Costco, 79795 Hwy. 111, La Quinta, CA Based on the inspection, testing, and evaluation completed, UL considers the product to be suitable for application of the Field Evaluation Product Mark and for use in accordance with any conditions of acceptability stated in this report. 2 Conditions of Acceptability Except where otherwise stated in the product description and evaluation sections of this report, this evaluation and the application of the Field Evaluated Product Mark is subject to the following Conditions of Acceptability. 2.1 Except for like -for -like component replacement in the event of component failure, no change or addition to the product or system shall be made that would alter its construction, operation, function, layout, source of supply, physical location or operating environment. If such changes or additions to the product occur, the Field Evaluated Product Mark shall be considered invalid, and a separate evaluation shall be required to determine compliance with applicable product safety standards under the changed conditions. 2.2 The completed evaluation and application of the UL Field Evaluated Product Mark by UL does not assume liability on the part of UL and does not relieve the manufacturer, installer, user, or other relevant parties of their responsibilities. The product evaluation is based on adherence to sound engineering practices, and compliance with the applicable product safety standards and installation code. 2013-4236-FE Field Evaluation Services Report Page 3 of 9 2.3 This evaluation considered the risks associated with electric shock, fire, and casualy hazards as specified in the evaluation section of the report only. No other hazards were evaluated during this evaluation. 2.4 Unless otherwise stated in the product description, this product was evaluated for installation in an indoor, dry, normal environment only. The product was not evaluated for installation in any hazardous classified location as defined in the latest edition National Electrical Code as adopted by the National Fire Protection Association. The product was not evaluated for installation in an environment subject to rainfall, water spray, steam, or exposure to any corrosive chemicals that deteriorate the enclosure or components. 2.5 The UL Field Evaluated Product Mark shall not be considered as equivalent to the UL Listing Mark, UL Recognized Component Mark, or UL Classified Product Mark. The UL Field Evaluated Product Mark indicates compliance with the applicable parts of the Standards referenced in Section 3 at the time the Mark was applied, and considering only the final installation site. The applicable parts included in the evaluation are the construction review, markings, and those testing protocols that are non-destructive. 3 Referenced Standards • UL 891, Switchboards, 11th Edition, Revised 10/31/2012 4 Product Description Equipment Name: Modified Switchboard Description: The product evaluated consisted of an existing Square D, 4 .. sectionType 3R dead front switchboard located on the outside of the building that serves as the main electrical service. The modification evaluated consisted of a connection to the switchboard bus on the line side of the service disconnecting means to feed power from a roof mounted photo -voltaic (PV) system through one or more utility interactive inverters in accordance with Article 690.64 (A) of the National Electrical Code. The connections were made in the service disconnect section (Section 2 of 4) to the three ungrounded phase buses. All connections were made at existing bus splices using existing hardware and no modifications were made to the original bus structure. Listed bolt on wire connectors suitable for 2AWG to 600 MCM copper or aluminum conductors were utilized for the connections.

Unless corrective actions are described, a final evaluation is necessary to complete all remaining tests and verify that changes have rendered the equipment compliant. No Discrepancies Found 6 Evaluation Details The following specific areas were evaluated using the methods described. All items comply with the applicable parts of standard(s) referenced in Section 3.0, unless stated otherwise in Section 5.0 of this report. Additional characteristics and features unique to the product were further addressed as deemed necessary considering the final installation site, or as required by the applicable product safety standard(s). 6.1 Critical Components Method: The following critical components were inspected for evidence of Listing or Recognition according to UL policies: - Wire Connectors Results: The critical components are Listed or Recognized by a testing laboratory acceptable to UL according to UL policies. 6.2 Guarding of Live Parts Method: The product is visually inspected to ensure that all components were housed in a suitable enclosure and made effectively inaccessible to unauthorized persons. An articulated finger probe is used to measure access where necessary. Vent openings are verified not to align with potential discharge paths of gases expelled from circuit breakers when clearing fault conditions. Results: Enclosures prevent contact with moving parts, electrically energized parts and hot parts. Enclosures provide an acceptable degree of protection for internal components (according to the product's installation environment). All electrically live parts external to the enclosure are 2013-4236-FE Field Evaluation Services Report Page 5 of 9 guarded as required by the applicable standards. No electrically hazardous energized parts are accessible from the exterior of the ultimate enclosure as required by Section 110.27 of the NEC. 6.3 Mounting of Components Method: Components that support live parts and uninsulated current carrying parts are secured to prevent them from turning or shifting in position if such motion may result in a reduction of spacings below the minimum acceptable values. Friction between surfaces is not acceptable as a means of preventing shifting or turning of a live part. Result: Components are mounted such that they are fixed in place and protected from a reduction in electrical spacings and strain on wiring terminations. 6.4 Wiring and Wiring Methods Method: All conductors were inspected for Listing or Recognition by a nationally recognized testing laboratory according to UL policies. The conductors were examined for proper ratings (voltage, ampacity, temperature, flexibility, flame and environmental ratings) as required for the application. The wiring methods were verified to comply with the applicable standards and provide proper physical protection, including strain relief, where applicable. The wiring terminations were inspected for correct application, number of conductors according to their Listing and correct ampacity based on temperature ratings. Results: Details as follows: 6.4.1 Supply Connections The supply connection point(s) have proper terminals and identification provided. 6.4.2 Wiring Methods Internal wiring methods are in compliance with the requirements of the applicable standard(s). All wiring is routed, secured and protected from moving parts, external heat sources and sharp edges. 6.4.3 Separation of Circuits Unless provided with insulation rated for the highest voltage involved, low voltage and line voltage circuit wires within enclosures are segregated or separated by barriers. The product wiring for low voltage and line voltage circuits outside enclosures is installed in separate raceways orwireways. 6.4.4 Wire Terminations All wire terminations are suitable for the number and the size of conductor(s) installed. 6.4.5 Strain Relief External conductors, cable assemblies entering enclosures and internal conductors are secured to prevent strain being transmitted to terminations. 6.4.6 Conduit Connections All conduits, gutters, and wireways are properly supported and properly sized for the number and size of conductors. 7 Test Results The following tests verified that the product operates within normally expected parameters. Unless stated otherwise in Section 5.0, all the following items comply with the applicable part(s) of the referenced 2013-4236-FE Field Evaluation Services Report Page 6 of 9 standard(s).

November 15, 2012 COSTCO 999 Lake Drive Issaquah, WA 98027 ATTN: Mr. Craig Peal RE: Costco Wholesale — La Quinta, CA (Warehouse #638) 79795 Highway 111, La Quinta, CA 92253 Rooftop Photovoltaic System Addition (Solar Panels) ENW Project No. 05064007 Craig: As requested, Engineers Northwest, Inc. has reviewed the proposed solar panel layout sheet 638-E-201 dated 10-24-12 and Module Weight Estimate on Costco Roofs both prepared by Mangan, and has evaluated the existing seismic and gravity collateral loads of the building for the addition of this array. Collateral load is defined as the weight of additional permanent materials other than the basic building frame system and rooftop supported mechanical and HVAC equipment. Some examples are sprinklers, lights, electrical systems, partitions, and ceilings. It is understood the total proposed weight of solar panel equipment is estimated to be 118,617 pounds, The equipment will be uniformly distributed over the main building roof, (142,000 sf) resulting in an average weight of 118,617 pounds1142,000 sf = 0.84t psf. A single 64 inch x 40.1 inch Mitsuibishi MLU solar panel weighs 44 pounds maximum, resulting in a maximum local weight of 44 pounds117.82 sf = 2.47 psf. Engineers Northwest (ENW) is the original Engineer -of -Record for this building. The original building was designed under the 2001 California Building Code (CBC). The original design parameters are as follows: Wind: 70 mph (Fastest Mile), Exposure "C" Seismic: Zone 4, Ca = 0.47, Cv = 0.86 Roof Seismic Collateral Load: 2 psf, 4 psf between Grids 7 and 8 The main metal building consists of 101, CMU walls, steel columns, steel joists and beams and metal deck for roof. The metal roof was designed and supplied by Butler Manufacturing Company. e 9725 Third Ave NE, Suite 207 - Seattle, WA 98115 206.525.7560 - fax 206.522,6698 www.engineorenw.com November 15, 2012 COSTCO WHOLESALE — La Quinta, CA Page 2of3 The current building code is the 2010 California Building Code (CBC). The design Parameters for the current code are as follows: Wind: 85 mph (3 Second Gust), Exposure "C" Seismic: S$ = 1.5, S1 = 0.6, SDS = 1.0, SD1 = 0.6 Seismic Design Category "D" Comments and recommendations for both gravity and seismic lateral load cases are as follows: GRAVITY LOADS The original design gravity collateral load for the building is as follows: 8.0 psf for gravity load case for joists or 4.0 psf (6.0, psf at bakery) plus sprinkler main (4" diameter pipes and larger), whichever is applicable or governs. 4.0 psf for gravity load plus sprinkler main for Main frames. The typical actual collateral gravity load seldom exceeds 4.0 psf on any single joist; however, this may not be valid for all joists in the structure. The increased solar equipment local weight of 2.47 psf plus 4.0 psf of existing collateral loads will total 6.47 psf, which is more than the minimum design load specification of 4.0 psf. The main girder (frame) collateral loads will be 4.0 psf + (added solar equipment average) 0.84 psf = 4.84 psf. This exceeds the specified 4.0 psf. The superimposed roof gravity design live load is 20 psf for joists and 12 psf (reduced per code) at the main frames. This live load cannot practically occupy the same area concurrently due to solar panel coverage. Upon concurrence by the building official, the loads due the solar equipment, where the dead load collateral limits are exceeded, are considered as carried partially by the specified live load capacities. The new photovoltaic system loads onto the existing steel deck must not exceed the deck capacity per attached letter signed and sealed by Mike Heiting from Butler Manufacturing Company dated November 13, 2012, The photovoltaic system supplier must reconfigure their system as required to accommodate the metal roof designer's requirements. LATERAL LOADS For lateral design, seismic criteria governed over wind criteria. The original diaphragm forces were specified in the original contract documents. The current diaphragm loads, even with a 1 psf addition from the solar panels, is still less than the original diaphragm forces, For the shear walls and foundation, the current design Cx = 0.128 (ASD) is less than the original design C, = 0,153 (ASD). Even with 1 psf roof load addition from solar panels, the current seismic forces would not exceed the original design seismic forces.

The spared design criteria for this project Has the collateral load as 4 psf + sprinkler main and RTUs. Butler manufacturing dated the design bond on this criteria. With The above stated. Bahr would consider the solar panels as "live load". This would result in the roof secondaries having 16 psfavaHa61e for other live kumis and the main frames would have 10 psf available for other live loads. The remaining live load should be iriom than adequate to handle any expected loading.
