STANDARD TERMS & CONDITIONS

INVOICING SCHEDULE

BUYER agrees to pay to UTCP the Total Contract Price for the equipment and services
described in this Agreement, based on the following invoicing schedule:



| |  |  | [***]% of the Total Contract Price shall be invoiced by UTCP upon BUYER receiving funding from or one or more affiliates of Merrill Lynch, Pierce, Fenner and
Smith., Inc. (the Lender) under the terms of that certain Credit Agreement (the Credit Agreement) between BUYER and Lender dated as of August 31, 2008 (the Funding Date) and shall then be
due and payable by BUYER to UTCP within five business days of the Funding Date (the Funding Payment) in accordance with the payment terms below;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | [***]% of the Total Contract Price shall be invoiced by UTCP upon delivery of the first 50% of the Equipment to the Destination and shall then be due and payable by
BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment terms below (the First Delivery Payment);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | [***]% of the Total Contract Price shall be invoiced by UTCP upon delivery of the last unit of Equipment to the Destination and shall then be due and payable by
BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment terms below (the Second Delivery Payment);
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Subject to any Mechanical Completion Delay Penalties, [***] of the Total Contract Price shall be invoiced by UTCP upon the occurrence of Mechanical Completion (as
hereinafter defined) and shall then be due and payable by BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment and other terms below (the Mechanical Completion Payment). For
purposes of this Agreement, Mechanical Completion means the date upon which (i) BUYERs design, engineering, procurement, permitting, construction (except for punch-list items) and permanent installation of the
geothermal electricity plant that incorporates the Equipment (the Facility) is complete, the Commissioning Test shall have been completed for each unit of Equipment and there shall have been a Successful Commissioning Test as
defined in Exhibit D-1, (ii) BUYER is in receipt of applicable turnover packages, (iii) the Facility is capable of operating safely in accordance with applicable laws and prudent electric power industry practices.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Subject to any Performance Penalties, [***] of the Total Contract Price shall be invoiced by UTCP upon the occurrence of a Successful Performance Test (as
hereinafter defined) and shall then be due and payable by BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment and other terms below (the Successful Performance Test
Payment). For purposes of this Agreement, Performance Test means a performance test conducted by or at the direction of BUYER and in accordance with the methodologies set forth in Exhibit D-2 hereto. A

(the Test Period), provided, however, that if the total Facility hot water resource flow rate (Total Facility Flow) is less than the Aggregate Corrected Flow (as such term is defined in Exhibit D-1), the
Performance Benchmark shall be adjusted in accordance with the following formula: 10.35 MW * (Total Facility Flow / Aggregate Corrected Flow) (the Adjusted Performance Benchmark). Notwithstanding the foregoing, the Performance
Test shall be deemed a Successful Performance Test for purposes of determining payments and for calculating Performance Penalties (defined below) under this Agreement if the result of the Performance Test meets the criteria set forth in this
paragraph with the Performance Benchmark set at 10.0 MW (the Contract Performance Benchmark).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Funding Payment is
meant to cover the cost of lead-time sourcing, product support and equipment processing, and is non-refundable. In the event UTCP has not received the Funding Payment, the First Delivery Payment or the Second Delivery Payment, in full, by their
respective due dates then UTCPs Delivery Date obligations under this Agreement shall be extended on a day-for-day basis for each day that the Funding Payment, the First Delivery Payment or the Second Delivery Payment, as the case may be, is
past due.

Each payment will accrue
interest from the date it is invoiced until the date it is received by UTCP, at a rate of 1.5% per month. In no event shall any such interest be deemed to be a penalty but shall be solely construed as an administrative charge to UTCP arising
out of BUYERs late payment. BUYER shall reimburse UTCP for any expenses, including reasonable attorneys fees, incurred in collecting any overdue payments, and in no event shall the payment hereunder exceed any applicable federal or state
usury laws.

UTCP shall submit invoices for payment to BUYER at the address incorporated under the section herein entitled NOTICES, if any, or as otherwise
directed in writing by BUYER.

The prices set forth in this Agreement are firm, provided that if BUYER delays delivery of the units of Equipment (as
defined in Exhibit A) from the applicable agreed-upon Delivery Dates, then BUYER agrees to pay UTCP any increased costs that it incurs from third parties based on such delay, including any rerouting or other shipping costs, any storage and
rigging fees, and any price increases from suppliers of the units of Equipment being purchased under this Agreement or any services under this Agreement that, in all cases, are the direct result of such delay.

SECURITY INTEREST

BUYER hereby grants to UTCP a continuing
second priority security interest in and lien upon all of BUYERs right, title and interest in and to the Equipment (the Collateral) to secure BUYERs payment of the Total Contract Price; provided however that if (i) BUYER
has failed to pay an amount that is due under this Agreement, and (ii) BUYER has repaid in full all amounts outstanding under the Credit Agreement, then BUYER shall grant to UTCP a continuing first priority security interest in and lien upon
the Collateral. Upon payment in full of the Total Contract Price (subject to adjustments thereto for Performance Penalties or Mechanical Completion Delay Penalties pursuant hereto) the security interest and lien of this Agreement shall automatically
terminate and UTCP shall take such actions (at UTCPs sole cost and expense) as are reasonably requested by BUYER to release the Collateral from the security interest and lien granted by this Agreement. The validity and enforceability of the
security interest and lien created pursuant to this Agreement shall be subject to UTCP entering into a subordination agreement with the Lender containing subordination and other terms and conditions satisfactory to the Lender (the
Subordination Agreement).

For as long as the Total Contract Price remains unpaid, in whole or in part, BUYER agrees to provide UTCP with
prompt written notice of the occurrence of any Event of Default (as hereinafter defined). In addition, BUYER will maintain insurance covering the Collateral as is customary for businesses similar to the business of BUYER and will promptly name UTCP
as loss payee, as its interests may appear, of any insurance now or hereafter covering the Collateral. BUYER will pay promptly when due all taxes and assessments on the Collateral or for its use or operation, except for taxes and assessments which
are being contested in good faith. Upon any failure of BUYER to pay any such taxes and assessments within five business days after notice from UTCP, UTCP may at its option discharge any taxes (which are not being contested by BUYER) to which any
Collateral is at any time subject. In addition, upon the failure of BUYER to do so, UTCP may purchase insurance on any Collateral and pay such amounts as may be reasonably necessary for the repair, maintenance or preservation thereof. BUYER agrees
to reimburse UTCP on demand for any payments or expenses incurred by UTCP pursuant to the foregoing authorizations. BUYER will promptly execute and deliver to UTCP such financing statements, certificates, notices and other documents or instruments
as may be necessary to enable UTCP to perfect or from time to time perfect, renew or continue the security interest granted herein. BUYER hereby authorizes UTCP to take all action (including, without limitation, the filing of any Uniform Commercial
Code Financing Statements or amendments thereto without the signature of BUYER) that UTCP may deem necessary or desirable to perfect or otherwise protect the security interest described hereunder.

Each of the following shall constitute an event of default (an Event of Default) hereunder: (a) BUYER becoming insolvent, making an assignment
for the benefit of creditors or making or sending a notice of intended bulk transfer, or if a committee of creditors is appointed for, or any petition or proceeding for any relief under any bankruptcy, reorganization, arrangement, insolvency,
readjustment of debt, receivership, liquidation or dissolution law or statute now or hereinafter in effect (whether at law or in equity) is filed or commenced by or against BUYER or any of its properties or a receiver or trustee is appointed for
BUYER or any of its properties and is not released or terminated within 120 days of such filing or appointment, as the case may be; (b) any merger, consolidation or other business combination involving BUYER or the sale of all or substantially
all of the assets of BUYER where the surviving entity fails to assume all the obligations of BUYER under this Agreement by operation of law or pursuant to an agreement reasonably satisfactory to UTCP; or (c) the failure to pay any installment
of the Total Contract Price pursuing to the Invoicing Schedule, in whole or in part, and after taking into account all adjustments thereto for Mechanical Completion Delay Penalties and Performance Penalties, within thirty (30) calendar days
after notice by UTCP to Buyer of such failure;

Upon the occurrence of any Event of Default such default not having been remedied within 30 days of its
occurrence or waived by UTCP, subject to the terms of the Subordination Agreement, UTCP shall have the following rights and remedies: (i) all rights and remedies provided by law, including, without limitation, those provided by the Uniform
Commercial Code as in effect in the State of Connecticut from time to time (the UCC); and (ii) the right to take possession of the Collateral and in addition thereto, the right to enter upon any premises on which the
Collateral or any part thereof may be situated, without notice, and remove the same therefrom. All rights and remedies available to UTCP pursuant to the provisions of this Agreement, applicable law and otherwise are cumulative, not exclusive, and
are enforceable alternatively, successively and/or concurrently by UTCP.

MECHANICAL COMPLETION DELAY PENALTIES

The full Mechanical Completion Payment amount shall only be due and payable by BUYER to UTCP if Mechanical Completion occurs on or prior to the Guaranteed Mechanical Completion Date (as hereinafter defined). For
purposes of this Agreement, Guaranteed Mechanical Completion Date means December 1, 2008; provided that UTCP agrees that it shall use commercially reasonable efforts to reach Mechanical Completion as soon as possible
following the Access Date (defined below). In the event that Mechanical Completion does not occur on or prior to the Guaranteed Mechanical Completion Date, the Mechanical Completion Payment amount shall be reduced by [***] for each day that
Mechanical Completion is not achieved by the Guaranteed Mechanical Completion Date (the Mechanical Completion Delay Penalties). Should Buyer not incur any penalties (including, but not limited to, required prepayments to its
Lenders under the Credit Agreement or to its investors under the Limited Liability Company Agreement of BUYER) as a result of Mechanical Completion not being achieved by December 31, 2008, then any accrued Mechanical Completion Delay Penalties
shall be forgiven. In the event that Mechanical Completion is not complete by December 31, 2008, UTCP shall be paid [***] per piece of Equipment that has successfully completed the Commissioning Test prior to December 31, 2008 and the
remaining balance due in the Mechanical Completion Payment shall be withheld and the reduction of [***] per day shall be applied to the balance until Mechanical Completion is achieved or the balance has been liquidated.

The Parties acknowledge and agree that the Initial Start-up and completion of the Commissioning Test of each unit
of Equipment prior to the Guaranteed Mechanical Completion Date requires that (i) each unit of Equipment be fully installed in conformance with UTCPs Conditions Required For Timely Start-Up/Commissioning Of Purecycle® 225 Powerplants At Raser Therm0 #1 Site and (ii) UTCP be provided with access to the Facility at least forty-five (45) days prior to the Guaranteed Mechanical Completion Date (the
Access Date). BUYER shall provide UTCP with all necessary facilities and infrastructure to run the Commissioning Test of each unit of Equipment on or before such Access Date. At a minimum this shall include necessary hot and cold
water flows and the ability to import and export power sufficient to service blocks of Equipment of no fewer than five (5) units at a time. Such facilities shall be provided in a manner to permit UTCP to conduct the Commissioning Test on any
five co-located units within the facility. BUYER shall complete UTCPs installation requirements and guidelines prior to the Access Date for each unit of Equipment and BUYER shall provide access to UTCP as it completes the installation of each
piece of Equipment to permit UTCP to complete pre-commissioning activities as early as possible. The Guaranteed Mechanical Completion Date shall be extended by one day for each day after October 15, 2008 that the Access Date has not occurred
(the Delayed Access Date.

In the event that (i) all units of Equipment are not fully installed in conformance with UTCPs
installation requirements and guidelines and/or (ii) UTCP has not been provided with full access to the Facility for the Initial Start up mobilization prior to the Access Date, and as a result, UTCP is required to perform the Initial Start up
and/or the Commissioning Tests at times or during days when UTCPS workers are entitled to overtime or premium rates, Buyer agrees to reimburse UTCP for any and all incremental costs associated with the performance of Initial Start up and/or
the Commissioning Tests at overtime or premium rates.

PERFORMANCE PENALTIES

The full Successful Performance Test Payment amount shall only be due and payable by BUYER to UTCP upon the occurrence of a Successful Performance Test. In the event that Facility performance is below the Contract
Performance Benchmark, or the Adjusted Performance Benchmark, as applicable, the Successful Performance Test Payment shall be reduced in accordance with the performance penalty schedule attached hereto as Exhibit F (the Performance
Penalties). The Parties agree that if a Performance Test has not occurred within one-hundred and eighty (180) days following the Guaranteed Mechanical Completion Date, the entire Successful Performance Test Payment shall be forfeited
by UTCP.

UTCP LIMITED STEP-IN RIGHT

If a
Performance Test is not completed within sixty (60) calendar days of the Guaranteed Mechanical Completion Date, then UTCP may exercise its rights under the Step-In and Standstill Agreement, dated as of the date hereof (the Step-In and
Standstill Agreement).

UTCP CONSTRUCTION INFORMATION RIGHTS

BUYER shall promptly send, or cause to be sent, copies of the monthly progress reports to UTCP that BUYER sends to the Lender; provided, however, that BUYER is entitled to redact confidential, privileged or other
sensitive information therefrom. During the design, engineering, construction, commissioning and performance testing of the Facility, BUYER shall provide a UTCP representative with reasonable access to the Facility and to BUYERs
representatives, agents and subcontractors to enable UTCP to monitor the progress of the Facility.

UTCPS RECEIPT OF INDEPENDENT
ENGINEERS REPORT AND ACCEPTABILITY THEREOF

The obligations of the Parties under this Agreement shall not be effective until: (i) UTCP
has received a final Lenders Independent Engineers report (the Engineers Report or the Report) from R.W. Beck, Inc. (the Independent Engineer); and (ii) the Report shall
be acceptable to UTCP in its reasonable discretion. UTCP shall provide written notice to BUYER acknowledging receipt of the Report and its acceptance to UTCP thereof. For the avoidance of doubt, no payments will be due from BUYER to UTCP until UTCP
has provided such notice to BUYER.

In the event the Report is not reasonably acceptable to UTCP, UTCP and BUYER shall work together in good faith for 15
calendar days after UTCPs receipt of the Report to resolve UTCPs concerns; such resolution may include, without limitation, a written amendment to this Agreement.

REPURCHASE OPTION

In the event that: (i) the Facility has not been placed into commercial operation within six (6) months after the date Mechanical Completion occurs due to events or circumstances not directly caused by or related to the Equipment
or UTCPs material breach of this Agreement; (ii) BUYER is not diligently working toward placing the Facility into commercial operation; and (iii) BUYER has repaid in full all amounts outstanding under the Credit Agreement, then UTCP
shall have the right, but not the obligation, to repurchase the Equipment for an amount equal to the portion of the Total Contract Price received from BUYER; provided, that in the event UTCP repurchases the Equipment, neither Party shall thereafter
have any liability to the other Party hereunder.

SERVICES AND MATERIALS FROM UTCP

UTCP WILL PROVIDE SERVICES REQUIRED FOR INITIAL START-UP OF THE UNITS OF EQUIPMENT DELIVERED AS SET FORTH ON EXHIBIT B. INITIAL START-UP SHALL MEAN THE
FIRST START-UP OF THE EQUIPMENT DELIVERED FOLLOWING COMPLETION OF INSTALLATION AT BUYERS SITE SUCH THAT THE UNITS OF EQUIPMENT ARE READY FOR BUYERS NORMAL OPERATION. UTCP MAY PROVIDE ANY OR ALL OF THE SERVICES REQUIRED UNDER THIS
AGREEMENT THROUGH A UTCP-AUTHORIZED SERVICE PROVIDER. BUYER WILL BE RESPONSIBLE FOR SITE PREPARATION AND INSTALLATION PRIOR TO INITIAL START-UP AS OUTLINED UNDER BUYERS RESPONSIBILITIES BELOW.

Except as expressly stated herein, UTCP shall not be required to provide any materials related to the Equipment or to provide any services relating to the Equipment,

herein and are not supplemented or amended by any such materials. UTCP shall review and comment on BUYERs installation design drawings and related materials and shall acknowledge to BUYER in a signed writing that it has reviewed said drawings
and related materials within 10 calendar days after UTCPs receipt of said drawings and related materials. UTCP makes no warranties or representations with respect to, and accepts no liability arising directly or indirectly from or in
connection with BUYERs drawings and related materials, or UTCPs review and/or comment on said drawings or related materials. BUYER is responsible in all respects for the design of the installation and for the installation of the
Equipment.

DELIVERY; TITLE; AND SHIPPING

UTCP
shall arrange and prepay shipping and transportation by carrier from the place of manufacture or supply, as applicable, to the Destination. All Equipment shall be manufactured and supplied within the United States and shipment thereof to BUYER shall
be FOB the place of manufacture or supply. UTCP will give BUYER written notice of the delivery date not less than three (3) weeks prior to the delivery date of the Equipment. BUYER is responsible for unloading the pieces of equipment at the

|LOGO |  | PureCycle® Model 225 Geothermal Power
System Limited Warranty Terms of Coverage |  | Exhibit C to Purchase Contract

UTC Power Corporation (UTCP) provides the
following Limited Warranty (the Warranty) for its PureCycle® Model 225 Geothermal Power System (PureCycle®
System) used in stationary power generation applications in the United States and Canada. This warranty applies to the first purchaser (the Buyer) only during the warranty period and is not transferable without written approval of
UTCP.

Coverage & Warranty Period

UTCP warrants that any standard component of the PureCycle® System [defined as a standard production PureCycle® System (i.e. the following components and interconnects: the evaporator, the power module and the condenser supplied by UTCP, and
the mechanical and electrical interconnects supplied by UTCP between such components)] that is properly installed, commissioned by UTCP or a UTCP Authorized Service Provider (ASP), operated in accordance with the specifications provided
by UTCP and found by UTCP under normal use and service to malfunction during the warranty period solely as a result of material defects in materials or workmanship, will be replaced or repaired at UTCPs option.

This coverage is limited to replacement parts and reasonable transportation and labor, as defined by UTCP, for component removal, repair or replacement, and
reinstallation during the first eighteen (18) months after the date of shipment or twelve (12) months from commissioning, whichever occurs first.

This Warranty shall be declared null and void if a commissioning checklist is not received by UTCP within
twenty-five (25) days of commissioning the PureCycle® System.

UTCP or an ASP must perform
all preventive maintenance and repairs during the Warranty period. Failure to comply with the recommended preventive maintenance procedures as scheduled in the applicable Operation and Maintenance Manual, and provide UTCP a field service report
(FSR) documenting that this preventive maintenance has been performed, and UTCP being in receipt of such FSR within twenty-five (25) days of the maintenance being required as per the schedule, will result in this Warranty being
declared null and void. Buyer must provide and maintain a dedicated analog telephone line or internet service with long distance direct dial and answer capability for UTCPs remote monitoring service.

Malfunctions

Malfunctions and defects do not include normal wear and tear, fluctuation in the heat source or consistent lack of heat from the heat source, effects of corrosive and/or erosive environments, fuels or heat sources, condenser or evaporator
fouling, degradation of performance, damage to PureCycle® System due to installation errors, replacement of consumables (including filters) or performance changes caused by these
conditions.

Malfunctions do not include nuisance faults that arise from incorrect configuration of parameters based on customer-supplied data, inadequate
or inconsistent heat supply, or inconsistencies as provided at electrical interfaces.

PureCycle® Replacement Parts

PureCycle® System parts supplied by UTCP under this Warranty for replacement or repair of any workmanship or material defect will carry a Warranty period that is equal to the
remaining Warranty period and coverage of the original PureCycle® System parts, or ninety (90) days from installation, whichever occurs last.

Repairs Under Warranty

All repairs under this Warranty must be conducted by UTCP or an ASP, using only new, remanufactured, or rebuilt PureCycle® System component parts supplied by UTCP or its designated
supplier. During the Warranty period any use of or substitution of parts other than those supplied by UTCP or its designated supplier will void the Warranty. All claims under this Warranty must be made to UTCP within the Warranty period and within
twenty-five (25) days of the malfunction of the PureCycle® System. Claims made outside of the Warranty period or after the allowed twenty-five (25) days are not valid and will be
rejected. All parts replaced under this Warranty shall become property of UTCP and shall be returned to UTCP.

EXHIBIT D-1

COMMISSIONING TEST PROCEDURE

A four (4) hour Commissioning Test for each unit of Equipment
will be conducted in general accordance with the American Society of Mechanical Engineers (ASME) Performance Test Code (PTC) 1. A site specific Commissioning Test procedure developed in general accordance with ASME PTC-1 will
be mutually agreed upon by the Parties, such agreement not to be unreasonably withheld. The site specific test procedure will be provided to the Parties prior to the commencement of the Commissioning Test sufficiently in advance to provide a
reasonable period of time to permit a review thereof without causing undue delay to the commencement of the Commissioning Test. The site specific Commissioning Test Procedure shall incorporate and shall be substantially comprised of the
following:



| | 1. | Step One:
| | -- | ---------



| | a. | Operate each unit of Equipment at the optimal gross electrical output and record the following test parameters for each unit of Equipment (each a Test Parameter and
collectively, the Test Parameters):
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net electrical output (Net Output)
| | - |  | ------------------------------------



| |  |  | Hot water resource temperature (Resource Temp.)
| | - |  | -------------------------------------------------



| |  |  | Hot water resource flow rate (Resource Flow)
| | - |  | ----------------------------------------------



| |  |  | Cooling water temperature (Cooling Temp.)
| | - |  | -------------------------------------------



| |  |  | Cooling water flow rate (Cooling Flow)
| | - |  | ----------------------------------------



| | b. | Recordings for each Test Parameter are to be taken at 10 minute intervals throughout the four (4) hour Commissioning Test period for a total of 25 Test Parameter data points.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | For each Test Parameter, the average of the 25 recorded Test Parameter data points will be used for purposes of Step Two of Commissioning Test procedure.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Step Two:
| | -- | ---------



| | a. | Using Figure D1, determine nominal Resource Flow based on the measured Resource Temp. from curve in Figure D11(the Nominal Resource Flow).
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------



| | b. | Using Figure D2, calculate Cooling Water Flow Deviation by comparing the measured Cooling Flow to the nominal Cooling Flow of 928 GPM and identify correction factor using
solid curve in Figure D2 (Cooling Flow Correction Factor).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | Using Figure D2, calculate Cooling Water Temperature Deviation by comparing the measured Cooling Temp. to the nominal Cooling Temp. of 65F and identify correction factor
using dotted curve in Figure D2 (Cooling Temp. Correction Factor).
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1 | Figure D-1 has been developed based on UTCPs predictive thermodynamic model. If actual resource conditions are outside the conditions shown in the correction curve in
Figure D-1, the same model will be used to generate updated correction curves, which shall be confirmed by UTCP recreating those curves with the data at the actual operating conditions. At the time the updated correction curves are developed, the
original correction curves will be recreated and plotted with the new curve and compared to the original Figure D-1.
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | d. | Calculate corrected Nominal Resource Flow based upon equation in Figure D3 (the Corrected Resource Flow).
| | -- | -----------------------------------------------------------------------------------------------------------

Successful Commissioning Test:

The Commissioning Test for all
units of Equipment shall be deemed successful (a Successful Commissioning Test) if (i) the sum of the measured Resource Flow of all units of Equipment (the Aggregate Resource Flow) is less than or equal to the sum of the
Corrected Resource Flow of all units of Equipment (the Aggregate Corrected Resource Flow) and (ii) the average Net Output of all units of Equipment is 250 kW or greater.

Conditional Site Requirements for Commissioning Test:



| |  | All Test Parameters will be recorded by Buyer, with assistance from Seller, utilizing Buyer supplied monitoring equipment (the Monitoring Equipment),
operated in accordance with the Monitoring Equipment manufacturers specifications and operating instructions.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The accuracy of all measured Test Parameters shall be determined in accordance with the Monitoring Equipment manufacturers specifications.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  | Monitoring Equipment accuracy uncertainties shall be applied to all measured Test Parameters (see example in Figure D4).
|- |  | ------------------------------------------------------------------------------------------------------------------------



| |  | Hot water resource pressures shall be sufficient to control dissolved gases, and maintain 10% margin above saturation pressure. Hot water pressure drop across the
evaporator of each unit of equipment (inlet to exit) shall exceed 12psi.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Buyer will manage Facility cooling tower operation to maintain a constant Cooling Temp. and Cooling Flow during the four (4) hour Commissioning Test period. If
a constant Cooling Temp. or Cooling Flow cannot be maintained during the Commissioning Test period, then the Commissioning Test will be postponed until constant Cooling Temp. or Cooling Flow can be maintained.

| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | Cooling Flow measured at 900 GPM with uncertainty of 30 GPM results in a correction factor at 870 GPM of 1.03
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | Cooling Temp. measured at 66F with uncertainty of 2F results in a correction factor at 68F of 1.06
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | Resource flow measured at 260 GPM  13 GPM (uncertainty) = 247 GPM

The Facility Performance Test shall be conducted in general accordance with ASME PTC-1 to
the extent applicable to organic Rankine cycle systems. be mutually agreed upon by the Parties, such agreement not to be unreasonably withheld. The site specific test procedure will be provided to the Parties prior to the commencement of
the Facility Performance Test sufficiently in advance to provide a reasonable period of time to permit a review thereof without causing undue delay to the commencement of the Facility Performance Test. The site specific Facility
Performance Test Procedure shall incorporate the following requirements.

A. The facility shall be Mechanically Complete and all major equipment shall be
in place and functioning. The Commissioning Test Protocol for the individual generation units shall have been satisfactorily completed.

B. Operate the
facility for a 10 day (240 hour) period of time with the generation units balanced within utility requirements for power factor (lead/lag) and generate at least 2,285,280 Kwh (10,350 KW x 240 hours x 92%) during the test period. The measurement
shall be facility net generation at utility meter or equivalent.

C. Power metering for the facility shall be recorded and documented. The metering
equipment shall be available for inspection.

D. Notification of the test shall be given to all parties prior to its commencement and a representative
shall be allowed to observe the operations during the test period.

E. All major equipment shall properly function and be capable of producing in
accordance with its intended purpose and in accordance with all permits and regulatory and safety standards.

F. Metering and measurement shall be in
accordance with utility standards. All meters will include both analog and digital output boards following the most current standard specifications. The metering design package will include two revenue quality meters, a test switch, and all data
inputs and outputs terminated at a metering interposition block. One meter will be designated the primary meter and will be used for EMS data that includes bidirectional KWH quantities, and instantaneous MW, MVAR and per phase voltage data.

G. The parties shall not be aware of any deficiency or operational problem which would not allow the facility to operate as intended for sustained
duration.

H. The Facility Performance Test shall be adjusted in accordance with procedures established in Exhibit E of the Purchase Agreement and shall
take into account deviations in cooling water flow and temperature and resource flow and temperature. The Facility Performance Test shall be deemed successful if the metered (measured) energy of the Facility as adjusted by Exhibit E standards is in
excess of 2,285,280 Kwh.
