Oates, City Manager Date: May 26,2011 Re: Alaska SeaLife Center Energy Performance Contract Project Background: In spring 2009 the Alaska SeaLife Center(ASLC)commenced a Facility Improvement preliminary audit with Siemens Industry- Building Technologies Division(Siemens). The preliminary audit was completed in fall 2009 with a recommendation that the Center had the potential to achieve a potential 15-20% energy cost saving over 10 years with completion of Facility Improvement Measures(FIM). In November 2009,the ASLC signed a Letter of Intent(copy attached)with Siemens to perform an investment grade energy audit. This audit was completed over the winter 2009-2010 with a finding that a base energy project with a project cost of$808,435 could achieve annual utility and operational savings averaging$95,000 over a 20-year project useful life. Alaska Energy Efficiency Revolving Loan Fund Program(AEERLFP): The 2010 Alaska Legislature with the passage of SB 220 created the Alaska Energy Efficiency Revolving Loan Fund Program(AEERLP)under the Alaska Housing Finance Corporation that provides financing for permanent energy efficient improvements to buildings owned by regional educational attendance areas, by the University of Alaska, by the state, or by municipalities in the state. Eligible borrowers obtain an Investment Grade Audit(IGA)as the basis for making cost-effective energy improvements, selecting from the list of energy efficiency measures identified with the Audit. As a city owned facility,the ASLC cost-effective energy improvement measures identified in the Siemens audit are eligible for funding under the AEERLF Program. Loans are for a 15-year term maximum and there are no penalties for early loan payoff. Interest rates vary between 4.25%to 5%depending on the loan term. ASLC Proposal to the City: The ASLC is seeking your authorization for the city administration to make application for an AEERLP loan to finance the base energy project developed from the Siemens audit. I have attached with this letter the Detailed Investment Grade Audit(IGA)and Energy Services Proposal along with a cash flow analysis using a 5%annual interest rate financed over 14-years. This analysis shows the forecast energy and operational savings would retire the loan in just under 14-years, with cumulative net cash flow over 20-years of$815,4/14. •Page 1 .ti J • Memorandum to Seward City Council Alaska SeaLife Center Energy Performance Contract April 26,2011 Under the terms of the Siemens Performance Agreement(a draft copy is attached)Siemens provides a firm price for the identified scope of work and the savings generated from energy, operational and maintenance savings repay the financing. Energy and operational savings are guaranteed to offset the cost of the loan payments. Siemens guarantees that the energy savings meet or exceed the cost of the financing, otherwise they pay the difference. Siemens has the option of implementing additional improvement measures at their expense to meet the guarantee. Ongoing measurement and verification will ensure that the guaranteed energy savings continue for the contract term. Under the provisions of the AEERLP regulations(copy attached)the application documentation is as follows: 1. Loan Application signed and dated(AHFC Form AEELRP-1); 2. Corporate Borrowing Resolution authorizing the borrowing and authorized signers to enter into the loan transaction; 3. Evidence of title vesting in the property-copy of warranty deed of preliminary title report; 4. Copy of an approved Investment Grade Audit and list of selected energy efficiency measures(scope of work); 5. Copy of Performance Contract; and 6. Other documentation as reasonably requested by AHFC. Upon receipt of an application for a loan under the program,AHFC will review the information and either issue a term loan commitment letter, decline the loan, or pend for additional information. AHFC will require the following documents to be executed for the loan closing: 1. Promissory Note(there will also be promissory note executed by the ASLC to the city); 2. Loan Agreement(there will also be a loan agreement executed between the city and ASLC-could be accomplished as an amendment to City/ASLC Lease Operating Agreement; 3. Assignment of Performance Contract Payment Guarantee to AHFC by the city of the Siemens guarantee; 4. Approved scope of work, including anticipated draw schedule; 5. Legal opinion from city attorney regarding the transaction; 6. Any other documentation as requested by AHFC. The AHFC will assess a .50%loan fee at the time of closing which will be the obligation of the ASLC to pay. The ASLC would also the pay the city's reasonable costs in completing the necessary loan documentation. Benefits and Risks: Benefits • Cash neutral • Guaranteed reduction in energy usage;reduce carbon footprint • New systems reduce maintenance demands • Complements seawater heat pump system • Page 2 Memorandum to Seward City Council Alaska SeaLiife Center Energy Performance Contract April 26,2011 Risks • Don't achieve projected savings(mitigated by Siemens'performance guarantee) • SAAMS default on loan;lose assets(unlikely with cash neutral analysis) Security for the AEERLP Loan: SAAMS Board of Directors have indicated their willingness if necessary to give the City a security interest in its Arcade and Historic Railroad Depot properties. The collateral value of these properties determined by MIA appraisal report dated April 20, 2011 is . (The appraisal report will be delivered on April 20th. It is anticipated the Arcade lots will appraise$250,000 and Depot between $350-400,000. SAAMS has a principal balance owing on the Depot of$271,852 giving its current equity between $78,000-S128,000. The combined equity of the properties is estimated to be between $328,000-$378,000) Attachments: 1. Siemens Detailed Investment Grade Audit&Energy Services Proposal 2. Cash Flow Analysis-3/31/2011 3.

Siemens Industry, Inc. -4- Proprietary&Confidential December 2010 �Alaska SeaL.ife Center DETAILED INVESTMENT GRADE AUDIT " " " ' & ENERGY SIEMENS SERVICES PROPOSAL Section I - Executive Summary Background On October 20, 2009 the Alaska SeaLife Center(ASLC) signed a Letter of Intent (LOI) with Siemens Industry, Inc. Building Technologies Division (SIEMENS), an Energy Services Company (ESCO), to perform a Detailed Investment Grade Audit (IGA) with the intent of developing an Energy Savings Performance Contract (ESPC) Agreement. The following report documents the results of the energy study of the ASLC and provides the basis for the final development of an ESPC project. Program Objective The objective of this evaluation was to identify and analyze the operations of the ASLC and to identify Facility Improvement Measures (FIMs) that will combine to form a project that meets the requirements of the LOI. The intent was to focus on energy efficiency improvements with favorable paybacks, whereby capital improvements will be funded by energy and operational cost savings.

This incorporates the costs associated with the projects development, energy audit, and measurement & verification (M&V) set-up required during the first year for the project guarantee. ASLC Energy Project Implementation Cost= $760,315 Total Annual Energy Savings Value (Year 1) = $68,925 Simple Payback= 11.0 years This beneficial project is designed to reduce the ASLCs overall energy consumption and year-to-year utility expenditures and meet the stated 15-year cash flow criteria of the LOI. The Total Annual Energy Savings is based on anticipated first year energy unit costs. Siemens guarantees units of energy, not the commodity cost of energy, so these savings may fluctuate some based on the actual cost of energy in a given year. In general, the cost of energy increases over time and energy escalation is taken into account in most performance contracting cash flow scenarios. Previous discussions with the ASLC identified the following factors should be considered and incorporated to accurately represent the calculated energy savings over time: Energy Savings Captured During Construction (Year 0) = $4,794 Annual Energy Savings Escalation = 5% Annual Operation Savings Escalation = 3% Siemens Industry, Inc. - 6- Proprietary&Confidential December 2010 le Alaska SeaLife Center DETAILED INVESTMENT GRADE AUDIT SIEMENS , &ENERGY SERVICES PROPOSAL Remaining Project Challenges The development of this project has been challenging on multiple fronts. The on-going proactive measures by ASLC's staff to reduce energy consumption and the future installation of the sea water heat pumps have captured some of the energy savings potential identified during Siemens initial site evaluations. In addition, minimum consumption thresholds negotiated with local utility companies prevent the incorporation of extra demand-based savings created by installing the project FIMs. However, despite these challenges, the primary barrier to implementing this energy project has been securing project funding. Without funding, Siemens is unable to provide a complete ESPC Agreement. Throughout the past year the ASLC and Siemens have attempted to secure project financing numerous times in a variety of ways. Funding avenues jointly evaluated, but ruled out include: • Traditional Lenders — First National Bank of Alaska and Wells Fargo • Siemens Financial Services (SFS)— via Siemens Building Technologies & SFS direct • USDA Community Facilities Grants & Direct Loans • Federal grant funding via Legislative Insert • State grant funding leveraging regional Representatives in Juneau • American Recovery and Reinvestment Act (ARRA) • Rasmuson Foundation Support • Bonding options available via the City of Seward • Loans available if the City of Seward would share the ASLC's debit obligation The best remaining option for funding this project appears to be the State of Alaska's new Alaska Energy Efficiency Revolving Loan Fund Program (AEERLF) that is administered by the Alaska Housing Finance Corporation (AHFC). The AEERLF is designed to help public entities perform energy improvements to reduce energy consumption Statewide by 15% before 2025. This program would require the City of Seward (City) to apply for the loan for the energy improvement measures to be performed at the ASLC. Use of the AEERLF involves meeting the criteria of AHFCs Retrofit Energy Assessment for Loans (REAL) Manual. In general, it involves the following steps for energy performance contracts with guaranteed energy savings: 1) Submission of REAL Application & Preliminary Benchmarking Form to AHFC 2) Qualified ESCO (SIEMENS) prepares Investment Grade Audit (IGA) 3) Submission of IGA and Loan Application to AHFC This document would serve as the required IGA for this loan application. Other requirements of this State program include developing a project that cash fows neutral within 15 years and a minimum three (3) year performance guarantee. Siemens Industry, Inc. -7- Proprietary&Confidential December 2010 Alaska SeaLife Center DETAILED INVESTMENT GRADE AUDIT SIEMENS & ENERGY SERVICES PROPOSAL The annual cost for SIEMENS performance assurance service, also known as a measurement and verification plan (M&VP), with annual labor escalations is estimated to as follows: Year1 = $15,491 /Year 2 = $16,0341Year 3 = $16,595 This performance assurance is required for every year in which the savings are to be guaranteed by Siemens. It includes measurement and verification time for Siemens engineers to confirm energy savings and prepare an annual report. These costs would need to be added to the ASLC Energy Project Implementation Cost show above to support the REAL requirements. Siemens is willing to work with the City, ASLC, and AHFC to help draft up different cash flow scenarios once a project interest rate has been established. If possible, we hope to be able to help the City negotiate the most favorable payment schedule and terms. As soon as funding is secured, Siemens will be able to finalize and propose a complete Energy Savings Performance Contract (ESPC) Agreement. The ESPC Agreement requires that interest rates be established in order to structure a payment schedule that will cash flow neutrally for the term of the contract. Siemens remains committed to the ASLC and supporting this project to the point that it can be proposed and implemented as an ESPC Agreement. Optional Building Automation Support Another option that is not included in the final project scope is an annual service agreement was designed to support ASLCs operation of their new Siemens APOGEE automation system. This was to provide both remote and on-site operator support with technician travel for a full day in Seward: Building Automation System Service (Year 1) = $5,097 Annual BAS Service Agreement Escalation = 3.5% In addition, software and firmware updates were included every other year to keep the ASLCs system current and prevent a future obsolescence of the new building automation system. This increases the annual cost of the service agreement every other year to: Building Automation System Service (Year 2) = $9,288 Annual BAS Service Agreement Escalation = 3.5% These may be paid for directly with ASLC operating funds or out of this project's excess energy savings if the funding source permits their inclusion.

Baseline energy use for lighting was calculated based on existing lamps, ballasts, fixtures, lighting control systems, power measurements, and data collected from Watt Stopper data loggers. Upgrading the lighting system to reduce energy consumption will occur in two ways; the first reduction is to reduce the lighting system's input wattage and the second reduction is to reduce the hours of operation. Water Description General The Alaska SeaLife Center water fixtures such as water closets, urinals, and lavatories are not low volume, low flow devices. Presently the water closets require 3.5 gallons of water per flush and the lavatories have a flow rate of 1 gallon per minute. Water conservation efforts will help to contain the impact of future rate increases, yield utility savings on water supply and sewer charges, and reduce maintenance effort and costs associated with older domestic and sanitary water fixtures. On-site surveys indicated that the toilets currently installed at the Alaska SeaLife Center were installed during the original construction. Areas that have been targeted to reduce water consumption in these facilities include the following. • Water closets in both public and private areas that utilize older, high flush fixtures. These fixtures utilize 3.5 gallons per flush (gpf) as compared to the newer low flush technology that utilizes 1.6 gpf. Although some of the early versions of the low flush technology installed in the 1990s gained a poor reputation for failing to clear the bowl with a single flush, more recent versions of low flush technology operate as well as the high flush fixtures. • Existing lavatories utilize 1.0 gallons per minute (gpm) as compared to the newer technologies that utilize 0.5 gpm. Water Baseline Development The baseline water usage in gallons is modeled using data collected during the site survey and discussions with Alaska SeaLife Center personnel. The baseline calculation is shown by Equation 1.

Boiler#1 and #2 Boilers 1 and 2 are 80 hp, Cleaver Brooks, fire tube, hot water boilers. They have a rated input of 3,347,000 btuh and a max pressure of 30 psi. The boilers operate in a lead lag fashion based on boiler run time and/or alarm status. Boiler#3 Boiler 3 is a 500 kW, Sussman, electric, hot water boiler.

A set of valves will reroute the water to either provide cooling or heating as is required by the units. All AHUs on the Sea Water Heat Pump loop will receive either hot water or cooled water depending on whether the AHUs are calling for heating or cooling. Occupancy The heat pumps will operate year round as needed to meet the pre-heat load. It is assumed that both heat pumps will be operational when the fuel oil boilers are operational and that only one heat pump will operate when the electric boiler is operational. The system will operate 24 hours a day, 7 days a week. During the times when only one heat pump operates the system will function in a lead/lag control strategy so as to keep equal wear on both pieces of equipment. Heat Pump#1 and #2 Heat pump 1 and 2 are 90 ton, Trane, RTWD Series R, high efficiency, water cooled, 2 pass, helical rotary chillers. They have a rated output capacity of 1,080,000 btuh. Design for the evaporator is entering fluid temperature of 35°F, leaving fluid temperature of 27°F, and flow rate of 180 gpm. Design for the condenser is entering fluid temperature of 90°F, leaving fluid temperature of 120°F, and flow rate of 120 gpm. From the manufactures data for a high efficiency chiller the evaporator has rated minimum flow rate of 92 gpm and a rated maximum flow rate of 336 gpm. Likewise the condenser has rated minimum flow rate 95 gpm and maximum flow rate of 347 gpm. Pumping PMP-19&20 and PMP-21&22 are the new circulation pumps for the evaporator and condenser side of the Sea Water Heat Pumps. The pumps are controlled in Lead/Lag configuration with flow modulated using Variable Frequency Drives (VFD). The evaporator pumps are variable volume flow with a max rated flow rate of 360 gpm, with a pressure drop of 50 feet of head. The motors have a rated horse power of 7.5 hp. The condenser pumps are variable volume flow with a max rated flow rate of 240 gpm, with a pressure drop of 40 feet of head. The motors have a rated horse power of 5 hp. Heat Exchangers New heat exchangers are being installed for the heat transfer between the sea water and the evaporator loop: HX-3 for the condenser loop and HX-4 for the Domestic Hot Water loop. The information provided detailing the possible system design indicates that a set of heat exchangers may also be installed to recover heat from the exhaust streams of several of the fan systems. This heat recovery would be use to pre-heat the fluid entering the evaporator of the heat pumps. HX-3 has a design capacity of 1,380 MBH with a Hot Side entering fluid temperature of 37°F, exiting fluid temperature of 33°F, and a fluid flow of 700 gpm; and a Cold Side entering fluid temperature of 27°F, exiting fluid temperature of 35°F, and a fluid flow of 360 gpm.

Sea Water Heat Pumps Baseline Development In order to obtain the baseline energy use for the Sea Water Heat Pumps, design documents provided by the Alaska SeaLife Center and manufacturer's specifications were consulted. The load profiles developed for all AHUs and the DHW were summed together to develop the load on the new Sea Water Heat Pumps. Baseline Development for each AHU and DHW can be found in appropriate sections below. The electric load comes from the evaporator loop pumps, condenser loop pumps, and the chillers. The maximum electric loads for the pumps were calculated using the manufactures pump curves from the design data and Equation 7. Motor Efficiency was taken from EPACT 92 for enclosed motors at 1800 RPM based on the design motor horse power. Equation 7 FLkW = bhp x 0.746 PumpPower MotorEfficiency The maximum evaporator loop pump power was calculated to be 4.85 kW. The maximum condenser loop pump power was calculated to be 2.84 kW. To calculate the pumping energy that would be used with the varying flow of the loops, a linear relationship was assumed between the percent of loop flow and percent of load on the chillers (Equation 8). In every case, the calculated fluid flow was checked to make sure that it met the minimum and maximum flow requirements for the chiller. If the flows were less or greater then the manufactures specified flow rates the value used in the calculation was set to the manufactures flow rates. Equation 8 FluidFlow =%ChillerLoad x MaximumFluidFlow Based on observed behavior, the system should behave some what differently then this because the Temperature Differential across the Heat Exchangers and the Chillers tends to vary from the design during part load conditions. For the purpose of the baseline adjustment this was not considered because the electrical use associated with the pumps is minimal when compared to the total loads of the facility. The total heating load (Btuh) was calculated by summing the calculated loads for the AHUs and DHW, see appropriate sections below for details. Using the manufactures Maximum Capacity for the chillers and the summed loads a percentage load was calculated (Equation 9).

Constant volume pumps are used to pump water out of the tanks and thru a parallel filter bank. Flow is controlled through the filters by a set of valves mmlie that modulate to maintain a specific flow setpoint (Figure 38). After three days the filters are backwashed to remove the waste that has collected in the filters from the tanks. The process then repeats.

EXISTING CONDITION: The Alaska SeaLife Center building is of relatively new construction and has a typical modern lighting system. The building consists of three major areas: Offices, Laboratories and Public Gallery/Display Areas. The Office and Laboratories are almost exclusively 1st Generation T8 Fluorescent fixtures with electronic ballasts. Many of these fixtures are vapor tight and suspended Direct/Indirect models. The Public Gallery/Display Areas are quite a bit different. The Aquarium and SeaLife Display Areas utilize a number of specialized HID fixtures which are not slated for retrofit. The rest of these Public Gallery/Display Areas utilize a large number of incandescent and compact fluorescent track and can lighting to illuminate information and educational wall displays. The exterior lighting consists of 150 W and 400 W Metal Halide fixtures and 70 W and 1,000 W High Pressure Sodium fixtures. PROPOSED FACILITY IMPROVEMENT MEASURE: In the Office and Laboratory Areas, install new lamps and ballasts in all existing 4 ft. T8 fixtures. The new 3rd generation T8 lights and electronic ballast combination will have a reduced wattage while maintaining similar light levels to the existing. The electronic ballasts will have a low ballast factor. Install new Pulse Start Metal Halide kits in the exterior HID fixtures. SIEMENS will provide all of the lamps, ballasts, and fixtures. ASSUMPTIONS: In addtion to a reduction in annual kWh's, a lighting upgrade will provide a well-lit work environment which is critical to the productivity, comfort, health, and safety of all occupants. To promote comfort and productivity, the proposed upgrade designs specifies the appropriate fixture, lamp, and ballast combination to provide the appropriate lighting color, density, and disbursement while minimizing glare. An integrated, whole-system approach to lighting design maximizes quality, energy efficiency, esthetics, maintainability, and life-cycle costs. Siemens Industry, Inc. -52- Proprietary&Confidential December 2010 Alaska SeaLife Center' DETAILED INVESTMENT GRADE AUDIT SIEMENS &ENERGY SERVICES PROPOSAL Measurements were taken on the following seven lighting circuits (Table 16). The measured data characterize the power consumption of the most prevalent lamp types. During the post retrofit M&V phase of the project, electrical circuit measurements will be taken at the same exact locations to quantify the electrical demand savings due to lighting upgrades.

SIEMENS has proven experience redesigning task, accent, high-bay, decorative, historical and general lighting schemes. • Color rendering: The interaction of artifical and natural lighting is important for both visual clarity and aesthetics. Color rendering of independent luminaries is important as well as the combined effect of different lighting sources within defined areas. • Efficiency: Improving the efficiency of a lighting system is not limited to lamps and ballasts. New fixtures designed for maximum light output, reflector kit retrofits, manipulatingballast factors, and tandem-wiring of ballasts are a few ways in which maximum light output can be attained with minimum energy input. • Controllability: While attention is focused on increasing the efficieny of lighting systems, an equally important dimension to lighting management is controllability. Ideally, lighting systems will be energized only at those times as required by its illumination purpose. Often times, occupancy patterns are not predictable and those control systems that permit flexibility in scheduling or automated on/off control, provide the greatest benefit. There are certain instances in which there are opportunities to interface HVAC systems, as well as lighting circuits, to occupancy sensors for additional benefit. • Maintainability: This refers to the degree of ease in which the collective lighting systems of a building or group of buildings are maintained. Fixture and component life, fixture height and the effort required for cleaning and repairing Siemens Industry, Inc. - 53- Proprietary&Confidential December 2010 ON ce Alaska SeaLife Center DETAILED INVESTMENT GRADE AUDIT SIEMENS & ENERGY SERVICES PROPOSAL fixtures, quantity of lamps and ballasts, and the amount of unique repair parts (i.e. lamps, ballasts, lens, and sockets) are all vital components when determining system maintainability. Heating Penalty and Cooling Savings calculations are based on the total kWh reduction calculated for the lighting retrofit project. It is assumed that all the lighting energy to be saved occurs within the conditioned space. SAVINGS CALCULATIONS: Energy savings from each retrofit will be based on a statistically developed number of runtime hours for specific area types and the areas wattage reduction. The wattage reduction will be based upon the pre and post retrofit wattages. Stipulated runtimes were derived from measured data collected from a statistically valid sampling of various use type. The logger data was analyzed and divided into specific space types and then averaged to develop the Stipulated Runtime Hours for each of the space types. Cost savings will be realized by decreasing power requirements to the respective lighting systems resulting in a decrease in annual electrical energy usage (kWh). Lighting system inventory requirements will be streamlined by standardizing lamp, ballast, and component manufacturers for the buildings. New lighting systems will provide operational savings in the form of reduced ballast and lamp replacement costs. HVAC INTERACTION CALCULATION: The installation of a more efficient lighting system will reduce internal heat gains. The impact of the lighting improvement measure and other measures relating to building heat loss, have been evaluated using a heat loss study. A calculation of the interaction between lighting wattage reduction and heating loads was done.

F1M 2.00 Water Conservation Electric Savings: 0 kWh $0 Water/Sewer Savings 456,000 Gallons $2,945 Total $ Savings: $2,945 FACILITIES INCLUDED UNDER THIS MEASURE: • Entire facility. EXISTING CONDITION: Currently the water fixtures such as water closets, urinals and lavatories utilized at the Alaska SeaLife Center are not low volume, low flow devices. Presently the water closets require 3.5 gallons of water per flush and the lavatories have a flow rate of 1 gallon per minute. PROPOSED FACILITY IMPROVEMENT MEASURE: Change out fixture or fixture components to bring them in line with current low flow standards. This upgrade will include replacing 35 water closets, 6 urinals and installing low flow aerators for 28 lavatories. The new water closets will use 1.6 gallons of water per flush and the new lavatories will use 0.5 gallons of water per minute. ASSUMPTIONS: Values used to calculate stipulated savings were arrived to and agreed upon by SIEMENS and Alaska SeaLife Center. Annual use is shown in Table 19. The number of uses comes Siemens Industry, Inc. - 56- Proprietary&Confidential December 2010 Alaska SeaLife Center. DETAILED INVESTMENT GRADE AUDIT SIEMENS &ENERGY SERVICES PROPOSAL from a combination of visitor and staff estimates. Numbers for visitor use is based on 2009 visitor statistics, one flush and two hand washes per visitor. Staff calculations are 2.5 flushes for 90 employees for 200 working days per year and twice as many hand washes. Use for the lavatory assumes 30 seconds of washing at a flow rate of 1 gpm to be reduced 0.5 gpm. Table 19 Fixture Type and Annual Use Fixture Type Pre-Water Volume per Post-Water Volume per Number of Uses Annual Use(gal) Use(gal) (#) Use(gal) Toilets 3.5 1.6 200,000 380,000 Lavatories 0.50 0.25 400,000 100,000 SAVINGS CALCULATIONS: Energy savings for water conservation are based on the difference between the baseline water use and the retrofit water use. The difference between the gallons per flush for the toilets and the gallons per minute for the lavatories is applied to the baseline number of flushes and the number of hand washes. The baseline water usage is modeled using data collected during the site survey and discussions with Alaska SeaLife Center personnel. The post retrofit water usage is modeled using the baseline data and the new volumes and flows agreed upon by SIEMENS and Alaska SeaLife Center. FIM 4.00 Building Automation System Upgrade Total Electric and Fuel Oil Savings are broken out below as part of Building Automation System FIMs 4.03,4.04, and 4.06. FACILITIES INCLUDED UNDER THIS MEASURE: • Entire facility. EXISTING CONDITION: The Alaska SeaLife Center has been struggling with the existing obsolete building automation system for years. Outdated and unsupported hardware and software have resulted in much of the facilities existing control system being overridden and operated in a manual fashion. This has enabled the facility operators keep the building somewhat comfortable, but ultimately this FIM will capture the tremendous efficiencies possible with a functional and properly programmed building automation system. In addition, several different types of controls systems are currently installed throughout the ASLC facility. The control systems operate in a stand-alone fashion and do not communicate with each other. Therefore the facility is not functioning as an interactive whole —for example the boiler systems and air-handler systems operate autonomously at this time. Siemens Industry, Inc. -57- Proprietary&Confidential December 2010 • /� Alaska SeaLife Center DETAILED INVESTMENT GRADE AUDIT SIEMENS " & ENERGY SERVICES PROPOSAL Also the motor controls for select fans are currently being operated through the obsolete Cutler-Hammer IMPACC electrical system. The existing control system must interface with IMPACC system to control major fan motors. This is intended to be achieved through "smart" Advantage starters. These starters fail intermittently and the JCI interface has never communicated correctly with the motor starter system. The IMPACC hardware and software are now difficult, if not impossible to maintain and operate so many motor starters are overridden and run continuously. PROPOSED FACILITY IMPROVEMENT MEASURE: A new master Siemens APOGEE Insight building automation system (BAS) will be provided. This system is intended to allow operators complete supervisory control and monitoring capabilities of the HVAC systems. In addition, this will integrate many of the disparate systems together, reuse what is salvageable, and replace the control components that cannot be incorporated into the APOGEE system. This measure will include replacing the two existing NCM field panels in the control room with a new PXCM controller that will integrate to the existing JCI N2 unitary controllers currently networked through this panel. This will enable the ASLC to monitor and control all existing N2 devices from the new Insight BAS server. As part of this upgrade Siemens will reuse all existing N2 controllers and their associated control devices. It is Siemens intent to reuse all temperature sensors, valves, dampers actuators, relays, etc. Siemens will also provide a new server and operator workstation for the new graphical APOGEE Insight Advanced software with APOGEE Go and RENO options, and a laptop for remotely accessing the system. Two concurrent site licenses will be provided. Normally this would completely replace the JCI Metasys server, however ASLC can elect to have this old user interface remain if it is their only access point for other 3rd party equipment. This upgrade will add the ability to monitor seven life support relays that currently alarm locally at a basement wall cabinet. Four new CO2 sensors for outside air reset of two air- handling units will be provided and one new outside air CO2 sensor to be mounted in the outside air intake of an air-handler (preferably opposite the ocean). Also a total of four new uninterrupted power supplies will be added — one for each new PXCM field panel and desktop computer. In order to better control ASLC's slab heating, new BAS controls will be added to automate one zone of slab heat that is currently running wildly. Siemens will add a new strap-on return water temperature sensor for each of the existing 10 slab heat zones. The new sensors will be wired to spare slots on the each zone's respective existing N2 controller. A new exterior rain & snow sensor will be provided to control operation of all slab heat to reduce the heating run time of the system. The goal is to engage the BAS to maximize efficiencies lost by running slab heating manually. Siemens APOGEE will replace the existing Reliable control system currently controlling the central heat plant equipment. Where the system has been bypassed, Siemens will Siemens Industry, Inc. -58- Proprietary&Confidential December 2010 Alaska SeaLife Center' DETAILED INVESTMENT GRADE AUDIT SIEMENS &ENERGY SERVICES PROPOSAL reestablish connections to the BAS for efficient control of these heating systems. All end devices except analog temperature sensors will be reused. This upgrade will also replace the existing electric control devices currently controlling the domestic hot water equipment with BAS system compatible components to reestablish connections for efficient control of this system. During this BAS upgrade Siemens will optimize the HVAC systems sequence of operation wherever possible to utilize day/night setbacks, outside air and supply temperature resets, motor scheduling, and other measures described by FIMs 4.03, 4.04 and 4.06 below. Siemens will include 40 hours of on-site customer training. Lastly, in order to fully control the ASLCs ventilation system, Siemens will need to replace the motor controls for select fans currently connected to the obsolete Cutler-Hammer IMPACC electrical system. Siemens APOGEE BAS will need to control these motors directly if they are to be controlled efficiently. This FIM would require that eleven of the existing Advantage starters be replaced with external motor starters that can be easily controlled by the Siemens BAS via a low voltage contactor. Each starter will be wired to a spare digital output (DO) on an existing N2 controller nearby. ASSUMPTIONS: This scope of work is based on the existing JCI drawings dated 5/6/98, Reliable drawings dated 8/4/03, original electrical and mechanical schedules, and multiple site visits during the last year. We assume that all mechanical systems are in good working order prior to this scope of work being initiated. ASLC personnel have agreed to correct any known or discovered deficiencies that would prevent the optimal operation of the new BAS system in a prompt manner. In addition, Siemens assumes that existing variable frequency drives (manufactured by Cutler-Hammer and JCI) are fully operational so they can be reconfigured to be controlled by the Siemens BAS. This scope excludes work with the other existing buildings systems such as the CardKey access control system, Notifier fire alarm system, and CC1 V system. These systems will remain separated from the BAS and remain accessible via their current operator interfaces. No upgrades will be performed on these systems under this FIM. In addition all work associated with existing abandoned humidifiers is excluded and Siemens plans on reusing all of the existing control dampers and/or smoke/fire dampers. Existing control valves will be reused where practical. All motors receiving new motor starters will be reused. This FIM does not include balancing of any air or hydronic systems. Formal, third-party commissioning is also excluded as all system start-up and point-to-point check-out procedures will be completed per Siemens standard check-list methodology.

Even though the building has a BAS, it is not being actively used to manage space temperature setpoints. The space temperatures can be set back to a lower temperature setting between the hours of 6:00pm to 6:00am, seven days a week. PROPOSED FACILITY IMPROVEMENT MEASURE: Program the proposed new DDC system to implement Night Temperature Setback during heating period. The operating costs will be reduced by lowering the setpoint for heating (setback) to 65°F during unoccupied times.

DETAILED INVESTMENT GRADE AUDIT SIEMENS &ENERGY SERVICES PROPOSAL FACILITIES INCLUDED UNDER THIS MEASURE: • AHU-5 • AHU-6 EXISTING CONDITION: AHU-5 is a single duct, variable air volume system serving office and exhibit areas. Currently the unit operates continuously and provides 40% to 60% outside air ventilation regardless of the occupancy level. Supply air temperature was kept between 56°F and 64°F during data logging. AHU-6 is a single duct, variable air volume system serving office and exhibit areas. Currently the unit operates continuously and provides 50% to 75% outside air ventilation regardless of the occupancy level. Supply air temperature was kept between 46°F and 60°F during data logging. PROPOSED FACILITY IMPROVEMENT MEASURE: Implement Demand Control Ventilation strategy to AHU-5 and AHU-6. Demand Control Ventilation (DCV) is a control strategy that adjusts the amount of supply outside air based on the ventilation demands of the occupants. The ventilation airflow is determined by comparing the CO2 concentration of return air and the outside air. Return air CO2 concentration will be measured at two locations for each of the AHU5: one at office area common return and the other at visitor area common return. The ventilation airflow will be modulated to keep the difference between outside air CO2 concentration and higher of the two return air CO2 concentration (office or visitor area) to less than or equal to 700 ppm. This will provide just the right amount of ventilation to the occupied space thus reducing the energy consumption and improve the indoor air quality. ASSUMPTIONS: Required ventilation rate was estimated based on the maximum number of occupants in each of the AHU service area. Number of occupants in the building was gathered from facility survey(Table 24). Table 24 Maximum Hourly Number of Occupants in Office and Visitor Areas Office Workers Visitors Summer Visitors Winter 35 220 25 All of the office and visitor exhibit area is served by AHU-5 and AHU-6.

Mixed air temperature was calculated based on the outside air ventilation rate, outside air temperature, and return air temperature. Supply fan airflow was calculated based on the supply fan electrical load profile created. Supply airflow, mixed air temperature, and observed supply air temperatures were used to calculate the post retrofit heating load by each of the unit.

Once it is turned on the system operates 24 hours daily and 7 days a week. Once the weather conditions become favorable the slab heat is manually disabled. PROPOSED FACILITY IMPROVEMENT MEASURE: Program the proposed new DDC system to operate the slab heat when weather conditions call for it. The operating costs will be reduced by limiting the time that the slab heat operates to times when the outside air temperature is equal to or below 32°F and the outside air relative humidity is above 80%. Upon being enabled the slab heat will operate a minimum of 6 hours. ASSUMPTIONS: The baseline year weather data was used to calculate the number of hours that the slab heat would operate. Outside air temperature should be equal to or less then 32°F and the relative humidity should be equal to or greater then 80% for the slab heat to be activated. It is assumed that the slab heat will operate for a minimum of 6 hours upon being activated. SAVINGS CALCULATIONS: Slab heat control optimization savings for fuel oil and electricity were calculated by determining the hours that the outside air temperature and relative humidity meet the requirements for operation. The load profile for slab heat and outside air temperature was then used to determine the load for the operable hours. Pumping power calculated for the constant volume circulation pump was then applied to the operable hours.

The "before" case is called the baseline; the "after" case is referred to as the post-installation or performance period. Proper determination of savings includes adjusting for changes that affect energy use but that are not caused by the conservation measures. Such adjustments may account for differences in weather and occupancy conditions between the baseline and performance periods. In general, baseline and post-installation energy use can be determined using the methods associated with several different M&V approaches. These approaches are termed M&V Options A, B, C, and D. A range of options is available to provide suitable techniques for a variety of applications. Measurement and Verification Options There are four guarantee options to measure and verify savings: Option A— Measured Capacity Option B — Measured Consumption Option C — Main Meter Comparison Option D — Designated based on Simulation or Calculation Option A — Measured Capacity. This approach is intended for Facility Improvement Measures where, with a one-time measurement for specific equipment or system's instantaneous Baseline energy use, and a one-time measurement for specific equipment or system's instantaneous post-implementation, (Post) energy use can be measured. Baseline and Post energy consumption is calculated by multiplying the measured end use instantaneous capacity (i.e. kW, Gal/hr, BTU/hr) by estimated hours of operation for each mode of operation (i.e. hours, week, month). Option B — Measured Consumption. This approach is intended for Facility Improvement Measures where continuous periodic measurements for specific equipment or systems baseline energy use, and continuous periodic measurements for that equipment or systems post-implementation, (Post) energy use can be measured. Periodic inspections and consumption measurements of the equipment or systems will be necessary to verify the on-going efficient operation of the equipment and saving attainment. Option C — Main Meter Comparison. This approach is intended for measurements of the whole-facility or specific meter baseline energy use, and measurements of whole-facility or specific meter post-implementation (Post) energy use can be measured. Periodic inspections of baseline energy usage, operating practices, and facility and equipment, and meter measurements of the will be necessary to verify the on-going efficient operation of the equipment, systems, practices and facility, and saving attainment.

The 10 locations represent different space types namely: conference room, corridor, laboratory, mechanical room, private office, public restroom, and staff restroom. The reduction in the number of burn hours per year was calculated based on the data collected by the Watt Stoppers.

Study Approach In conducting a technical energy audit as a basis for a performance contract, it is essential that the existing conditions be precisely established as a baseline for the evaluation of any potential system improvements. Relevant factors were identified and assessed through a systems approach in an effort to develop potential energy improvement measures. The factors are outlined below: 1. Review of Facility Layout and Facilities The initial step in the study entailed familiarization with the facility layouts as well as a review of available drawings, and meetings with building operations personnel. The HVAC, building characteristics, and plumbing systems were investigated. 2. Review of systems Operation/Usage through system trending Since energy usage is dependent on how the facility is operated, it was necessary to collect data on operating hours and utilization. The HVAC systems were data logged between 12/12/2009 and 01/04/2010 to aid in establishing the baseline energy consumption. The monitored system includes the air handlers, hot water loops, and boilers. HVAC operating parameters, such as operation hours and ventilation airflows were determined through investigation of the monitored data, sequence of operations, and facility staff. The calculation methodologies for the determination of the operating parameters are detailed in Section II — Facility Descriptions. 3. Review of systems Operation/Usage through Facility Personnel Survey Other parameters that were used to define the baseline energy consumption include the occupancy schedules, equipment schedules, equipment sizes, and space temperatures based on the data logger analysis, the average space temperatures were defined for occupied and unoccupied hours: the observed occupied hour average space temperature is 70°F, and unoccupied hour average space temperature is 70°F. The equipment sizes are listed in Section II— Existing Building Conditions. 4. Development of Facility Improvement Measures Based on the field surveys, metered data and related calculations, the Facility Improvement Measures (FIMs) were developed. The measures were analyzed to determine their effect on the overall base energy consumption of each system impacted. Additionally, each measure was reviewed in a cost/benefit analysis. 5. Energy Usage Characteristics The most recent energy consumption data available for Alaska SeaLife Center covers October 2008 through September 2009 for electricity and fuel oil consumption. The utility information was provided by Alaska SeaLife Center. Baseline energy consumption is summarized in part D. Baseline Energy Consumption.

FIMs were calculated in an interactive manner for the facility. The savings for each FIM was then determined by calculating the difference between each energy model for each FIM. E. Operational Baseline Costs There are minimal savings to the Operational Baseline Costs which have been identified. According to the ALSC facilities personnel, no reduction in staff would result from these upgrades so no labor savings have been accounted for. The cash flow models apply $3,500 in operational savings and this value was provided by the ASLC. This is intended to account for the reduction in material costs associated with replacing old lighting ballasts and lamps. These savings will be continued through the first 3 years of this proposal to account for the 3-year new lamp warranty period. After that time, the savings will be reduced by approximately 50%to reflect ballasts material savings.

Unit Energy Costs and Annual Percentage Increase Utility costs used for savings calculations will be based on the utility rate in effect for the predominant bill or the utility rate in effect for the corresponding period of the Baseline period, whichever is greater. The rate, in effect during the Baseline period, will be designated the floor price. An escalation rate of 5% per annual period will be applied to the floor rates. The escalated floor rate will be compared to the utility rate in effect in each future annual period, and the greater of the two will be applied to the actual utility savings occurring in that annual period.

"Stipulated Savings"are a sub-category of Guaranteed Savings that do not require post-FIM implementation measurement and verification because they are agreed upon by the Parties based upon representations made to SIEMENS by the CLIENT and through the application of generally accepted analytical formulae. As such, Stipulated Savings are agreed upon in advance by the Parties and cannot be changed. When used as a methodology for representing a FIM's energy savings, such methodology is not recognized as a measurement and verification methodology under IPMVP. Therefore, where the IPMVP measurement methodologies are required, a methodology other than Stipulated Savings must be used to calculate energy savings. "Substantial Completion" or "Substantially Complete" means the Work, or any identifiable portion thereof, is sufficiently complete, in accordance with the provisions of this Agreement relating to the Scope of the Work and Services, Exhibit A, such that the CLIENT will be able to realize from such Work substantially all of the practical benefits intended to be gained therefrom, or otherwise employ the Work or the FIMs for their intended purposes. To the extent that the Work requires multiple Acceptances, the Work's final Substantial Completion date shall determine the Guarantee Date. "Therm"is a measure of energy equal to 100,000 BTUs. Page 7 of 19 Agreement PCA-100 PUBLIC version 2011 PERFORMANCE CONTRACTING AGREEMENT "Total Guaranteed Savings" means the sum of the Savings that are guaranteed for all Annual Periods during the Performance Guarantee Period (inclusive of the Construction Period, if applicable). The Total Guaranteed Savings are reflected in Tables 1.1 and 1.2 in the Performance Assurance, Exhibit C. "Work"means collective labor, Equipment and services comprising the FIMs to be performed by SIEMENS, as described in the Scope of Work and Services, Exhibit A. "Work Product Deliverable"means the tangible form of a report or drawing specifically prepared for, commissioned by and deliverable to the CLIENT in connection with the Work to be performed by SIEMENS under this Agreement.

No employee or agent of SIEMENS shall be, or shall be deemed to be, an employee or agent of the CLIENT. 3.4 SIEMENS represents,warrants and covenants to the CLIENT that: (a) It has all requisite corporate power to enter into this Agreement, and that its execution hereof has been duly authorized and does not and will not constitute a breach or violation of any of SIEMENS's organizational documents, any Applicable Law, or any agreements with third parties; (b) It has done and will continue to do all things necessary to preserve and keep in full force and effect its existence and the Agreement; (c) This Agreement is the legal, valid and binding obligation of SIEMENS, in accordance with its terms, and all requirements have been met and procedures have been followed by SIEMENS to ensure the enforceability of the Agreement; (d) To SIEMENS's best knowledge, there is no pending or threatened, suit, action, litigation or proceeding against or affecting SIEMENS that affects the validity or enforceability of this Agreement; and, (e) It is duly authorized to do business in all locations where the Work and Services are to be performed. 3.5 The CLIENT represents,warrants and covenants to SIEMENS that: (a) It has all requisite corporate power and/or statutory authority to enter into this Agreement, and that its execution hereof has been duly authorized and does not and will not constitute a breach or violation of any of the CLIENT's organizational documents, any Applicable Law, or any agreements with third parties; (b) It has done and will continue to do all things necessary to preserve and keep in full force and effect its existence and the Agreement; (c) This Agreement is the legal, valid and binding obligation of the CLIENT, in accordance with its terms, and all requirements have been met and procedures have been followed by the CLIENT to ensure the enforceability of the Agreement; (d) To the CLIENT's best knowledge, there is no pending or threatened, suit, action, litigation or proceeding against or affecting the CLIENT that affects the validity or enforceability of this Agreement; and, (e) The CLIENT has consulted with its legal counsel and is relying on the advice of its counsel concerning all legal issues related to this Agreement, and is not relying on SIEMENS in this regard. Page 8 of 19 Agreement PCA-100 PUBLIC version 2011 PERFORMANCE CONTRACTING AGREEMENT Article 4 Performance Guarantee 4.1 The Annual Realized Savings generated during each Annual Period will be no less than the Guaranteed Annual Savings as shown in Tables 1.1 and 1.2 of the Performance Assurance, Exhibit C, subject to the limits in Section 4.8. The measurement and verification calculation methodology for determining the Savings is set forth in the Performance Assurance, Exhibit C. 4.1.1 General. Except as otherwise provided, energy savings will be calculated for each month of each Annual Period as the product of(a)"units of energy saved"(kWh, Therms, GJ, etc.) multiplied by(b) "cost of energy." (a) Units of energy saved are calculated by 1) assuming the Contracted Baseline has been maintained per Section 4.3 below, and 2) subtracting the then current period measured units of energy consumed from the Baseline units of energy defined in Article 5 of Exhibit C. (b) Costs of energy are defined in Article 6 of Exhibit C-Utility Rate Structures and Escalation Rates. 4.2 Any future Escalation Rates to be applied to utility, energy or other costs are set forth in Exhibit C. SIEMENS and the CLIENT agree that the Baseline data set forth in Exhibit C is a full and accurate reflection of the existing Facility, equipment, operation, business use and energy usage, and that such Baseline data will be the basis on which all future energy use will be compared in order to determine the Annual Realized Savings. 4.3 SIEMENS and the CLIENT agree that the Contracted Baseline fully described in Exhibit C will represent the new operating and/or equipment profile of the Facility resulting from the FIM implementation. The Performance Guarantee is dependent upon and is subject to the express condition that the CLIENT operates and maintains its Facilities within the Contracted Baseline parameters, as may be adjusted in accordance with the terms herein, during the entire term of the Performance Guarantee Period. 4.4 The CLIENT agrees to notify SIEMENS prior to or within thirty (30) days of CLIENT's knowledge of any Material Change. 4.5 Within thirty (30) days of notice of a Material Change, SIEMENS's discovery of a Material Change and with prompt notice to CLIENT, SIEMENS will either: (a) Require an adjustment to the Performance Assurance and the Performance Guarantee as a result of the Material Change; or, (b) Where a commercially reasonable adjustment to the Performance Guarantee is unavailable,terminate both the Performance Assurance and the Performance Guarantee. 4.6 A Performance Guarantee Period savings reconciliation as identified in Section 4.1 will be performed at the end of each Annual Period as follows: (a) Within ninety (90) days of the Guarantee Date, the Construction Period Savings shall be reconciled and applied to the calculation of the first Annual Period's Annual Realized Savings. (b) At the conclusion of each Annual Period, SIEMENS will calculate the Annual Realized Savings and compare the calculated amount to the applicable Guaranteed Annual Savings amount. (c) Where the Annual Realized Savings are less than the Guaranteed Annual Savings, a Savings Shortfall shall be recorded for the applicable Annual Period. (d) A Savings Shortfall shall be paid by SIEMENS within sixty(60) days following the CLIENT's acceptance of the reconciliation and once paid SIEMENS shall have fulfilled its obligations under the Performance Guarantee for the applicable Annual Period. 4.6.1 As the mutual goal of the Parties is to maximize Savings, if SIEMENS can correct a Savings Shortfall through an operational improvement at no expense or material inconvenience to the CLIENT and without future operational expenses, and the CLIENT declines to allow such operational improvement,then any future Savings Shortfall that the improvement would have corrected will be negated by deeming the value of the Savings Shortfall as Savings achieved and adding the amount of same to the Annual Realized Savings calculations for each Annual Period thereafter. 4.7 The Performance Guarantee is dependent upon and is subject to the express condition that the CLIENT maintains the PASP during the entire Performance Guarantee Period. If the CLIENT fails to maintain, breaches, cancels or otherwise causes the termination of the PASP then; (a) The Performance Guarantee shall terminate immediately and be void and of no force or effect; or, (b) Where termination of the Performance Guarantee acts to render the Agreement in violation of Applicable Law, all Guaranteed Savings thereafter shall be determined to have been achieved and Page 9 of 19 Agreement PCA-100 PUBLIC version 2011 PERFORMANCE CONTRACTING AGREEMENT SIEMENS shall have been deemed to have met its Performance Guarantee obligations under this Agreement for each and every Annual Period thereafter without the obligation to provide the CLIENT, or any third-party as the case may be, with any further Annual Performance Assurance Reports. 4.8 The payments and credits based on Savings Shortfalls, if any, are the sole remedy of the CLIENT under this Performance Guarantee. ANY PAYMENTS MADE OR TO BE MADE TO THE CLIENT UNDER THE TERMS OF THIS PERFORMANCE GUARANTEE SHALL NOT EXCEED THE PAYMENTS ACTUALLY MADE BY CLIENT TO EITHER SIEMENS AND/OR A THIRD-PARTY (IN THE EVENT THAT THE CLIENT HAS FINANCED THE TRANSACTION) FOR THE AGGREGATE OF: THE PRICE, AS DEFINED IN EXHIBIT B, ARTICLE 1.1; THE PASP PAYMENTS; THE MSP PAYMENTS, IF ANY; AND, IF APPLICABLE, THE CLIENT'S COST OF FINANCING THE WORK. The CLIENT's cost of financing the Work is the cost of financing calculated either: (a) On the date that the escrow account is funded in accordance with Exhibit B, Article 1.2; or, (b) On the Effective Contract Date if the escrow requirement is expressly waived by SIEMENS. 4.9 The CLIENT represents that all existing equipment that is not installed by SIEMENS under this Agreement but is deemed necessary to achieve the Performance Guarantee, is in satisfactory working condition. Prior to the beginning of the Performance Guarantee Period, SIEMENS will have inspected all such existing equipment and reported any deficiencies to the CLIENT. To the extent that the deficiencies are not remedied by the CLIENT prior to the Guarantee Date, the adverse affect on the ability of the Project to attain the necessary Guaranteed Savings shall be factored into the Annual Performance Assurance Report and, if necessary, the Performance Guarantee shall be adjusted accordingly. 4.10 If the Equipment or the existing equipment is altered or moved by any person (including the CLIENT) other than SIEMENS or a person authorized by SIEMENS, the CLIENT shall immediately notify SIEMENS in writing, and SIEMENS reserves the right to perform a reacceptance test on, or if necessary a re-commissioning of, the system at the CLIENT's expense in order to determine if a Material Change has occurred. 4.11 SIEMENS will have no liability or obligation to continue providing PASP Services or any Guaranteed Savings under the Performance Guarantee in the event that the CLIENT fails to: (a) Authorize a re-acceptance test or re-commissioning that SIEMENS reasonably deems necessary in order to determine if a Material Change has occurred; (b) Provide access to any Facility where Work is to be performed; (c) Service and maintain all Equipment in accordance with the manufacturers' recommendations in order to prevent a Savings Shortfall; or, (d) Provide SIEMENS with accurate Facility operating information as soon as such information becomes reasonably available to the CLIENT, including energy usage and cost, executed preventive maintenance and repair records, building or equipment additions, and occupancy levels during each Annual Period. 4.12 Unless expressly contrary to Applicable Law, should the CLIENT decide to discontinue the PASP before the end of the Performance Guarantee Period, the CLIENT will give SIEMENS thirty (30) days prior written notice and in such notice indicate that the CLIENT has selected one of the following: (a) The CLIENT will re-invest the avoided cost of cancellation of the PASP into Facility improvements and services that improve the overall Facility's performance and which improvements and services are implemented by SIEMENS; or, (b) The CLIENT will pay to SIEMENS 50% of the remaining value left in the PASP Annual Period, as a liquidated damage and not as a penalty, to compensate SIEMENS for SIEMENS's up-front costs and expenses in preparing to perform the PASP as contracted for the Annual Period. 4.13 Unless expressly contrary to Applicable Law, any disputes concerning the calculation of the Annual Realized Savings or changes to the Contracted Baseline that are not resolved by negotiation between the Parties within thirty(30)days of the notice of the dispute, will be resolved by a third-party professional engineering firm which is reasonably acceptable to both SIEMENS and the CLIENT. The determination of such firm will be final and binding upon CLIENT and SIEMENS. SIEMENS and the CLIENT will each be responsible for half of the fees of such firm.

Options A through and including D are part of the IPMVP. Option E- Stipulated is based on industry accepted engineering standards and is the Option used for purposes of calculating Operational Savings. Option A - Retrofit Isolation: Key Parameter Measurement. Savings are determined by field measurement of the key performance parameter(s) which define the energy use of the FIM's affected system(s) and/or the success of the Project. Measurement frequency ranges from short-term to continuous, depending on the expected variations in the measured parameter and the length of the reporting period. Parameters not selected for field measurement are estimated. Estimates can be based on historical data, manufacturer's specifications, or engineering judgment. Documentation of the source or justification of the estimated parameter is required. The plausible savings error arising from estimation rather than measurement is evaluated. If applicable, the predetermined schedule for data collection, evaluation, and reporting is defined in Exhibit A, Article 3- Performance Assurance Services Program. Option B — Retrofit Isolation: All Parameter Measurement. Savings are determined by field measurement of the energy use of the FIM-affected system. Measurement frequency ranges from short-term to continuous, depending on the expected variations in the savings and the length of the reporting period. If applicable, the predetermined schedule for data collection, evaluation, and reporting is defined in Exhibit A, Article 3- Performance Assurance Services Program. Option C - Whole Facility: Savings are determined by measuring energy use at the whole Facility or sub-Facility level. Continuous measurements of the entire Facility's energy use are taken throughout the reporting period. If applicable, the predetermined schedule for data collection, evaluation, and reporting is defined in Exhibit A, Article 3- Performance Assurance Services Program. Option D - Calibrated Simulation: Savings are determined through simulation of the energy use of the whole Facility, or of a sub-Facility. Simulation routines are demonstrated to adequately model actual energy performance measured in the Facility. This Option usually requires considerable skill in calibrated simulation. If applicable, the predetermined schedule for data collection, evaluation, and reporting is defined in Exhibit A, Article 3-Performance Assurance Services Program. Option E — Stipulated: This Option is the method of measurement and verification applicable to FIMS consisting either of Operational Savings or where the end use capacity or operational efficiency; demand, energy consumption or power level; or manufacturer's measurements, industry standard efficiencies or operating hours are known in advance, and used in a calculation or analysis method that will stipulate the outcome. Both CLIENT and SIEMENS agree to the stipulated inputs and outcome(s) of the analysis methodology. Based on the established analytical methodology the Savings stipulated will be achieved upon completion of the FIM and no further Page 3 of 26 Siemens Industry, Inc., Building Technologies Division Exhibit C — Performance Assurance v. 2011 Exhibit C — Performance Assurance Alaska SeaLife Center Energy Performance Contract < CUSTOMER DRAFT > measurements or calculations will be performed during the Performance Guarantee Period.

Savings are determined by comparing prior usage, consumption or efficiencies (defined as the "Baseline") against the post-FIM implementation usage, consumption or efficiencies. The Baseline usage, consumption or efficiencies are described in this Exhibit C, Article 5. The post-FIM implementation usage, consumption or efficiencies is defined as the Contracted Baseline and are described in this Exhibit C, Article 7. 4.2 Option A - Retrofit Isolation: Key Parameter Measurement 4.2.1 Lighting Upgrade Description During the pre-installation study measurements were taken on 7 lighting circuits to characterize the power consumption of various lamp types. In order to optimize the amount of data measured, the most prevalent fixture types were measured. Table 4.2.1.1 identifies the locations of those 7 circuits and their respective physical locations. During the post retrofit M&V phase of the project, electrical circuit measurements will be taken at the exact same locations. This will quantify the electrical demand savings due to lighting upgrades. Energy savings from each retrofit is based on a statistically developed number of runtime hours for specific area types and the areas wattage reduction. The wattage reduction is based upon the pre and post retrofit wattages. Stipulated runtimes were derived from measured data collected from a statistically valid sampling of various use type. The logger data was analyzed and divided into specific space types and then averaged to develop the Stipulated Runtime Hours for each of the space types. Cost savings will be realized by decreasing power requirements to the respective lighting systems resulting in a decrease in annual electrical energy usage (kWh). Lighting system inventory requirements will be streamlined by standardizing lamp, ballast, and component manufacturers for the buildings. New lighting Page 7 of 26 Siemens Industry, Inc., Building Technologies Division Exhibit C — Performance Assurance v. 2011 Exhibit C — Performance Assurance • Alaska SeaLife Center Energy Performance Contract < CUSTOMER DRAFT > systems will provide operational savings in the form of reduced ballast and lamp replacement costs. The installation of a more efficient lighting system will reduce internal heat gains. The impact of the lighting improvement measure and other measures relating to building heat loss, have been evaluated using a heat loss study. A calculation of the interaction between lighting wattage reduction and heating loads was done to determine the heating penalty. Calculations No further calculations will be done.
