SECTION 4

GENERAL CONDITIONS

GENERAL CONDITIONS

GC-1 ENTIRE AGREEMENT



|1.1 | This Agreement embodies the entire agreement between Buyer and Seller. The Parties shall not be bound by or liable for any statement, representation, promise or understanding not
set forth herein. Nothing contained in proposals, correspondence, discussions, order acknowledgements or other of Sellers forms has any effect on this Agreement unless specifically incorporated herein.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1.2 | No modifications to this Agreement shall be valid unless reduced to writing and signed by both Parties pursuant to Clause GC-2 (Changes).
|--- | -----------------------------------------------------------------------------------------------------------------------------------------

GC-2 CHANGES



|2.1 | Buyer, through its authorized procurement representative, may at any time direct, in writing, changes, including but not limited to changes in any one or more of the following:
(1) drawings or specifications; (2) additions to or deletions from quantities ordered; (3) Delivery schedule; (4) method of shipment or packing; (5) place of Delivery. If any such change causes an increase or decrease in the
cost or timing required to provide the Equipment, or otherwise affects Sellers ability to meet its obligation, an equitable adjustment shall be made in the Agreement Price or Delivery schedule and/or other relevant terms and the Agreement
shall be modified by written amendments or revisions executed by authorized representatives. Any request by the Seller for adjustment under this Clause GC-2 (Changes) must be asserted promptly by written notice to Buyers authorized
representative and in no case later than within twenty (20) Days from the date of receipt by Seller of the notification of a change, unless the Parties mutually agree to extend the time required to assess and determine the resulting impact.
Buyer shall respond to Sellers request for adjustment within thirty (30) days of receipt of Sellers notice. However, nothing in this clause shall excuse Seller from proceeding with the order as changed. Failure by Seller to timely
give the required notice hereunder will preclude Sellers right to request any adjustment. In the event that Buyer and Seller are not able to reach agreement on a firm price for a Buyer directed change after good faith negotiations by the
Parties or in case of an emergency endangering life or property or the Facility has ceased operation or is materially and adversely affected in its operation requiring immediate corrective action, Seller will proceed with implementation of the
change on a time and materials basis, including a reasonable profit. In such event, Seller agrees to provide in a timely manner such documentation as is reasonably sufficient for Buyer to determine the accuracy of impact of jobsite changes on a time
and material basis.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.2 | If this Agreement requires Buyer to review and comment on Sellers technical documents, Seller shall submit, within twenty five (25) Days from the date of Sellers
receipt of such comments, any request for adjustment resulting from implementation of Buyers comments. No adjustment will be made hereunder unless Buyer, through its authorized procurement representative, confirms the change in writing.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3 | A Change in Law affecting Sellers Work under this Agreement (except for changes relating to taxes to be paid by Seller) and occurring after the Effective Date shall be
considered a change and will be handled in accordance with Clause GC-2.1 above, provided that Seller gives notice to Buyer of such Change in Law no later than ten (10)

days after
(i) Seller becomes aware of such Change in Law or (ii) the earlier time at which it would be commercially reasonable to expect that Seller should have become aware of such Change in Law, together with details as to the impact of such
Change in Law on performance of the Work.



|2.4 | Suspension instructed by Buyer pursuant to Clause GC-7 (Suspension) will also be treated as a change and will be handled in accordance with Clause GC-2.1 above, unless such
suspension arises as a result of any fault, defect or other failure to perform which is attributable to Seller.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

GC-3 DELIVERY

Performance and Delivery of the Sellers obligations shall be in accordance with the Guaranteed Milestone Dates. However, to the
extent the Buyers failure to fulfill any of its material obligations under this Agreement, (except payment obligations), actually and demonstrably delays Seller in the performance of its critical path activities, Seller shall be entitled to an
equitable adjustment to the affected Guaranteed Milestone Date(s), except to the extent that Seller fails to exercise good faith efforts to mitigate the impact of such Buyer delay and provided in any event that Seller must give notice to Buyer
within ten (10) days after (i) Seller becomes aware of the occurrence of such Buyer delay or (ii) the earlier time at which it would be commercially reasonable to expect that Seller should have become aware of such occurrence. Such
notice will specify the nature of the occurrence and the reason(s) why Seller believes additional time should be granted and the length of the delay occasioned by reason of such Buyer delay. Strict compliance with this Clause GC-3 (Delivery) is a
condition precedent to any entitlement to an extension of the affected Guaranteed Milestone Date(s). Failure by Seller to timely give the required notice hereunder will preclude Sellers right to invoke the protection of this Clause GC-3
(Delivery) to the extent the Buyer is prejudiced by such failure. Seller shall use its reasonable best efforts to minimize or avoid the delay caused by the Buyer delay and the initial notice provided by Seller shall describe in detail the efforts of
Seller that have been or are going to be made in this regard. Upon mutual agreement of the Parties to Sellers entitlement for an equitable adjustment to the affected Guaranteed Milestone Date(s), this Agreement shall be modified by written
amendment or revision executed by the Parties authorized representatives.

GC-4 TITLE AND RISK OF LOSS



|4.1 | Title to Equipment or materials to be shipped from within the United States shall pass to Buyer when available for shipment from the manufacturers factory. Title to Equipment
or materials to be shipped from a country other than the United States shall pass to Buyer at the port of export immediately after the Equipment or materials have been cleared for export. Title to services provided by Seller shall pass as such
services are performed and accepted by Buyer. In order to protect Buyer or Owners interest in Equipment with respect to which title has passed to Buyer or Owner but which remains in the possession of Seller, Seller shall take or cause to be
taken all steps necessary under the applicable laws and regulations to maintain Buyers or Owners title and to protect Buyer or Owner against claims by other parties with respect thereto.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.2 | Shipment to Storage. If the Equipment cannot be shipped to Buyer, as specified in this Agreement, due to any cause attributable to Buyer, Seller may ship such Equipment to storage.
If such Equipment is placed in storage, including storage at the facility where

consent of the Indemnified Parties, such consent not to be unreasonably withheld so long as such settlement completely discharges or releases the indemnifiable claims against the Indemnified Parties and does not impose by way of consent decree,
injunction or otherwise any restraint or limitations on such parties; operations or upon the operation or other use of the Facility. Buyer acknowledges it may be required to enter into certain license agreements, which shall be provided by Seller at
no additional cost to Buyer or Owner, with regard to the use of Seller proprietary computer software.

suit or proceeding involving Indemnified Parties in which such infringement is alleged, and Indemnified Parties shall permit Seller to control completely the defense or compromise of any such allegation of infringement in which case Seller may
select counsel after consultation with Indemnified Parties, provided that (i) Buyer is consulted and kept reasonably informed of the claims, litigation, and negotiations, (ii) Indemnified Parties shall be entitled at Indemnified
Parties expense to participate in such defense, and (iii) no compromise shall be adverse to Indemnified Parties without such partys consent and (b) Buyer shall render such reasonable assistance at Sellers cost in the

with those available to the Seller, and that such conflict materially prejudices the ability of the counsel selected by the Seller to represent both Parties, such Indemnified Party shall have the right to select separate counsel reasonably
acceptable to the Seller to participate in the defense of such action on its own behalf at Sellers expense.

|5.4 | If any claim, suit, action, proceeding or investigation arises as to which the indemnity provided for under this Clause GC-5 (Infringement) hereof may apply and Seller, after being
given written notice by the Indemnified Party promptly upon becoming aware of such claim, suit, action, proceeding or investigation, fails to assume the defense of, or to diligently defend, such claim, action, proceeding or investigation, then the
Indemnified Party may, upon giving prior notice thereof to Seller, at the expense of Seller, contest (or, with the prior written consent of Seller, settle) such claim.

contractors or suppliers based upon the calculated EEAF of the Sellers Equipment. If and to the extent that such shortfalls are in Buyers opinion (acting reasonably, fairly and equitably) the responsibility of Seller, Buyer (acting
reasonably, fairly and equitably) shall assess and apportion responsibility to the Seller.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | Buyer shall give written notice to Seller of any determination of responsibility under this clause, and of any resulting assessment and obligation to pay liquidated damages to Buyer
on a weekly basis. Buyer will promptly provide Seller with full details of all relevant calculations and with copies of all relevant correspondence and other documents upon which such determination, assessment and attribution were based.

| | c. | With respect to Reliability LDs, if Owner does not recover or seek to recover from Buyer liquidated damages for failure to achieve the guaranteed Facility EAF under the Prime
Contract, Buyer shall not be entitled to recover Reliability LDs under this Agreement for Sellers failure to meet his guaranteed EEAF.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d. | In no event shall the Reliability LDs recoverable from Seller be in excess of the amount of Reliability LDs recovered or sought from Buyer by Owner for failure to achieve the
Buyers guaranteed Facility EAF under the Prime Contract.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | e. | Buyer has the sole right to determine and declare which tests or series of tests will be used to demonstrate the overall Facility performance, provided however, with respect to the
720 hour Reliability Test, in the event that the Guaranteed EAF is not met, Buyer shall select the period in which the Facility achieved the highest EAF.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | K. | Performance Tests shall be run in accordance with this Appendix 4. Buyer shall give Seller reasonable notice of the date or dates on which the Performance Tests shall begin.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | L. | The Parties agree that it would be extremely difficult and impracticable under the presently known and anticipated facts and circumstances to ascertain and affix the actual damages
that Buyer would incur should the Facility meet the Minimum Facility Performance Criteria but fail, due to reasons attributable to Sellers Equipment, to meet the Facility Performance Guarantees and/or Reliability Guarantee. Accordingly, the
Parties agree that the amounts specified herein for Performance Liquidated Damages and Reliability Liquidated Damages are not intended as penalties but rather as reasonable projections of damages that Buyer might incur for failure to meet the
Facility Performance Guarantees and Reliability Guarantee, respectively.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | M. | Provided the Facility has achieved Final Completion and the Equipment has met the Minimum Performance Criteria, Sellers maximum aggregate cumulative liability for Performance
Liquidated Damages and Reliability Liquidated Damages shall be as set forth in Special Conditions Clause SC-30.3, entitled Limitation of Liability.

PERFORMANCE GUARANTEES AND LIQUIDATED DAMAGES



| | C. | Performance Liquidated Damages:
| | -- | -------------------------------

If in the
Completed Performance Test, Sellers Equipment Performance Guarantees are not met due to a failure of Sellers Equipment to meet the Equipment Performance Guarantees as defined in Section 2, Appendix F, Steam Turbine
Generator Thermal Performance Requirements, Guarantee Case, for reasons attributable to Seller, Seller shall pay as Performance liquidated damages, and not as a penalty, an amount calculated at the rate shown below for any deficiencies in
meeting the Equipment Performance Guarantees.

Table 3.1 Performance Liquidated Damages



|                                           |  |                      |  |                                                       |   |

Notwithstanding the above, Sellers Noise Guarantee shall be a Make Right
guarantee.

Sellers right to liquidate any shortfall in the Equipment Performance Guarantees is contingent upon the Seller achieving
the Minimum Performance Criteria. If Sellers Equipment fails to achieve the Minimum Performance Criteria then the Seller has a Make Right obligation with respect to the Minimum Performance Criteria.

The Equipment must meet each Equipment Performance Guarantee, unless specifically stated otherwise. Excess performance in one Equipment Performance
Guarantee shall not be allowed to offset shortfalls in performance of another Equipment Performance Guarantee.

With respect to those
Equipment Performance Guarantees for which Performance Liquidated Damages are provided, the payment by Seller to Buyer of such Performance Liquidated Damages in accordance with this Appendix 4 shall be Buyers sole and exclusive remedy in full
and final satisfaction of Sellers liability for performance shortfall., subject to the provisions of Clause 6.0, Paragraph C of this Appendix 4 imposing on Seller costs of any retesting to the extent Performance Tests fail for reasons
attributable to Seller.

not be less than ***%
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Reliability Test: The Reliability Test consists of a 720-hour period of operation of the Facility, will be conducted in accordance with the procedures and protocols described
in Clause 7.0 below, and is a requirement for achieving Final Completion.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Seller shall participate with Buyer in a
Reliability Test to demonstrate to Owner that the Facility can achieve an Equivalent Availability Factor of 92% or better during the 720 hour Reliability Test period.

The period of testing for the Reliability Test shall commence whenever the Facility is ready after the startup of the Facility and continue until the Facility has achieved the guaranteed Equivalent Availability Factor
or better over a period of 720 hours, but not beyond the Guaranteed Final Completion Date. Subject to Clause 2.0 J.e, above, Buyer may at any time look back over the test data and designate the time period to be declared as the Reliability Test.
Full outage due to Force Majeure events or interruptions because the power purchaser cannot or will not accept power, and the related time required to shut down and restart for these outages, will not be counted as test hours and will extend the 720
hour test period.



| | a. | The Equipment Equivalent Availability Factor (EEAF) and the Facility Equivalent Availability Factor (EAF) shall be logged from the date of commencement of the Reliability Test.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | Buyer will make all reasonable efforts to allow Seller access to the Equipment in order to minimize repair time.
| | -- | ----------------------------------------------------------------------------------------------------------------



| | c. | Buyer will advise Seller when any event occurs which affects the EEAF.
| | -- | ----------------------------------------------------------------------



| | d. | Seller may have personnel present to monitor operation until the guarantee period has been completed.

7.0 TEST PROTOCOLS AND PROCEDURES



| | A. | Guarantee Conditions
| | -- | --------------------

All Facility Performance Test
results will be adjusted analytically for deviations from the Guarantee Conditions as set forth in the Facility Test Procedures. Performance degradation of the steam turbine generator will be considered, as agreed between Buyer and Owner.

Facility and Equipment Performance Tests will be conducted as soon as practical after the initial turbine operation. To account for turbine
aging, an adjustment to Turbine Cycle Net Heat Rate and Turbine Gross Power Output will begin to accrue from zero (0) value beginning on the date of initial synchronization. The adjustment methodology will be based on the following method:

| |  |  | Comparing the results of an enthalpy drop efficiency test run on the turbine sections in the superheated region with the startup enthalpy drop test results (enthalpy drop tests
performed by the Seller). For the purposes of this adjustment methodology, the LP degradation will be assumed to equal half the IP Turbine percent degradation.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the event that an initial enthalpy drop test cannot be performed, the following will apply:



| |  |  | Reviewing the operating and chemistry test logs, inspecting flow measurement elements in the cycle for deposits, and employing other methods for ascertaining the condition of the
unit as described in ASME PTC 6 Report  1985, Section 3.07 (Refer to Figure 3.3)
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Test Interruptions
| | -- | ------------------

With the exception of the
Reliability Test, any test interruption attributable to Buyer experienced during a Facility Performance Test or Equipment Performance Test will require the re-testing of the applicable Facility or Equipment Performance Guarantees. Test data gathered
from the Facility or Equipment Performance Test prior to the interruption shall be discarded. If a test interruption occurs for reasons beyond the control of Buyer, it shall be mutually agreed to either: (a) resume the Facility or Equipment
Performance Test after the cause of the test interruption has been rectified, or (b) restart the Facility or Equipment Performance Test.

Upon the occurrence of a Facility or Equipment Performance Test interruption, Buyer shall notify Owner in accordance with the performance test procedure. Upon notification of an interruption, Buyer and/or Seller, with Owners
assistance will identify the cause, define the procedure for continuing or stopping the Performance Test or Equipment Performance Test, and identify the responsibility for any costs incurred for re-testing.

Reliability Test Interruption means any period of time the Facility is out or derated because of Force Majeure, unavailability of fuel, Owner
scheduled outages (other than at Buyers request), faults of the electrical grid, and failure of Owner to operate the Facility in accordance with the station operating manuals. Reliability Test Interruptions will be excluded from the
Performance Test period for test data analysis and the Performance Test shall continue when the interruption is corrected. Reliability Test Interruptions will extend the test period by an amount of time equal to the interruption. Reliability Test
data collected before the interruption may be included in the analysis.

Periods of exceedance of emissions limits defined in the Air Permit
shall be treated as a Reliability Test Interruption pursuant to the previous paragraph (for the duration of the exceedance period), except for periods during which the emissions exceedance resulted in a Facility derating or shutdown.

Upon a Facility trip caused by the Work, Owner will not be required to return the Facility to service unless the root cause of the trip has been
identified and the problem has been corrected.

SECTION 5, APPENDIX 4

PERFORMANCE GUARANTEES AND LIQUIDATED DAMAGES

Any time period during a test for which a test interruption occurs that is beyond the control of Buyer and Seller will be excluded from the test period for test data analysis. Any interruption that is the consequence of failure of equipment
to meet operating requirements shall not be a test interruption and shall not be excluded from the test period for test data analysis. Types of interruptions excluded from the test period shall included interruptions caused by Force Majeure, test
instrumentation malfunction, unavailability of design fuel or other materials, problems in disposing of discharge materials, and operating and dispatching decisions and other causes outside Buyers and Sellers control except as otherwise
provided with respect to dispatching decisions during the Reliability Test. The Reliability Test periods may, at Buyers option, be continuous except for permitted test interruptions per above.

Operator action/inaction, inconsistent with Prudent Utility Practices, or not in accordance with (or inconsistent with) the performance test procedures,
causing a failure to meet the Guaranteed Emissions levels will not constitute an emissions violation or test interruption, unless such action or inaction is at the direction of Buyer and Seller. Emissions data from an exceedance period attributable
to operator action/inaction will be excluded from analysis. All other data collected during such an exceedance period, at Buyers and Sellers joint option, will be included in the analysis.

The failure of nonessential automatic controls and instrumentation will not preclude initiation of the Reliability Test, or require a Reliability Test
interruption if Buyer determines that the failure or unavailability of such instrumentation would not require a Facility shutdown during normal operation.



| | C. | Test Procedures
| | -- | ---------------

Seller shall submit, the later of
75 days after receipt of plant P&IDs or 365 Days before the Guaranteed Substantial Completion Date, procedures for the tests which shall include name of item to be tested, location of measurement points, manufacturer and model number of major
instruments to be utilized, any applicable correction curve(s) for off-design conditions, and a verifiable method of calculation (sample calculation) of the test results.

The performance of Sellers Equipment will be based on acceptance tests in accordance with Section 5, Appendix 4, Attachment 5.

The Performance Tests of the Facility shall be performed using a combination of permanent Facility instrumentation and special test instrumentation for measurements.

Seller shall be required to support the overall Performance Test program. Seller-supplied Equipment will be required to be operated in the normal
configuration and be monitored as the Performance Tests are completed.

Seller shall report the results of the each Equipment Performance
Test (unless aborted) to Buyer. Buyer will report the results of each Performance Test (reflecting overall Facility performance) to Owner.

| | B. | Instrumentation  General Requirements
| | -- | --------------------------------------



| | 1. | Instruments shall be classified as Primary and Secondary instrumentation. A Primary Instrument is defined as any instrument used to collect data required to calculate the corrected
test results (e.g. the measured parameters must enter into the calculation algorithm for turbine heat rate or turbine net power output). All other instruments are Secondary Instruments.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Primary Instruments are further categorized as Class 1 and Class 2 instrumentation. Class 1 Primary Instruments are those instruments that are used to
collect data that are used to calculate the test results, and have a sensitivity of 0.2% change in corrected test results / % change in primary variable or greater. Any other primary instrument is a Class 2 Primary Instrument. Key Primary
Instrumentation details are included in Table 1.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Secondary Instruments shall be identified in the test procedure. Secondary Instruments are variables that are measured or determined but do not enter into the calculation of
performance. Existing station instrumentation and data collection system are utilized to gather information from Secondary Instruments. No laboratory calibration is required, and Buyer is under no obligation to ensure the data quality or
availability of any Secondary Instrumentation.

| | C. | Instrumentation  Key Measurements
| | -- | ----------------------------------



| | 1. | Feedwater Flow
| | -- | --------------

Feedwater flow shall be measured with the
use of an ASME throat tap flow nozzle manufactured in accordance with ASME standards including an upstream flow conditioning device (flow straightener). At least two tap sets of the Feedwater flow nozzle shall be calibrated at Reynolds numbers as
high as reasonably possible at a minimum of 20 calibration points. The discharge coefficient will be calculated from the calibration data. Extrapolation of the discharge coefficient, if necessary, shall be done using the methodology outlined in PTC
6 (2004) and PTC 6A (2000). Adequate pipe straight lengths of ASME-MFC-3M-1989 will also be ensured. The flow rate shall be determined from the methodology detailed in ASME-MFC-3M-1989 as the average flow calculated from the calibrated taps and
the corresponding calibration data. Feedwater Flow nozzle should meet the criteria of ASME PTC 6.

The feedwater flow meter will be
installed after the initial flushing of the system. Prior to installation, it will be visually inspected for damage. Buyer shall notify Seller in advance of this inspection date. Prior to the Equipment Performance Test, a bore scope inspection
shall, upon request of the Seller, be performed on the flowmeter from an upstream port to ensure that there are no visible changes of the flowmeter. The inspection of the flowmeter shall be conducted during a planned shutdown of sufficient

length of time to allow such inspection. However, the time period between the post-test inspection and testing should not exceed two weeks.

For the condition with two tap sets being calibrated, the flow rate for each tap set shall be determined from the methodology detailed in ASME-MFC-3M-1989
using the discharge coefficient obtained from the aforementioned methodology. The flow shall then be determined for each of the two tap sets. The calculated flow from each element will be obtained by averaging the two flow values

Buyer and Seller agree that the flowmeter described above shall be sufficient for use in the turbine heat rate and electrical output testing efforts. In
the event that the Buyer has not adequately incorporated the provisions specified under this Section C.1 for the feedwater flow meters, then the test tolerance shall be increased pursuant to Section H of this Attachment 5 to Section 5. To
determine the test uncertainty difference associated with the flowmeters, ASME PTC 6-Report 1985 shall be used as a guide.

Any instrument not listed above that is subsequently determined to be necessary for the testing
efforts shall be detailed in the Sellers test procedure.

Accuracy Class means the base accuracy of an instrument, as
defined by the instrument manufacturers published documents, prior to considering potential errors caused by drift, hysteresis, improper installation, improper ranging, etc.



| | D. | Instrumentation  Calibration and Inspection
| | -- | --------------------------------------------



| | 1. | All primary instruments will be calibrated as detailed in Table 1, unless exception to this requirement is specifically taken herein.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------



| | 2. | All secondary instruments need not be calibrated at all.
| | -- | --------------------------------------------------------



| | 3. | When calibration of a test instrument is required, the test instruments will be calibrated or re-calibrated prior to testing in accordance with standard industry practice. In
general, all test instrumentation requiring calibration will be calibrated (or re-calibrated) within 90 days of the test. As exceptions to this requirement, the following calibration frequencies will be required:
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Class 1 Primary Flow Elements  Laboratory calibration per ASME PTC 6  2004 Standards (No re-calibration required)
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | Instrument PTs/CTs  Certification of class accuracy only
| | - |  | ---------------------------------------------------------



| |  |  | Passive Instrumentation (RTDs, Thermocouples, etc.)  Calibrated (or re-calibrated) within six (6) months of the test
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Class 2 primary flow elements (e.g. RH spray, SH spray, etc.) and secondary flow elements- no calibration required
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | Electrical Metering (Class 1 primary)  within manufacturers recommended calibration frequencies
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | Electrical Metering (Class 2 primary)  no calibration required
| | - |  | ---------------------------------------------------------------

The calibration frequency of other types of instruments not listed above requiring extreme measures (e.g. shaft speed pickup) for re-calibration shall also be exempt from the requirements for calibration or
re-calibration. Laboratory calibration of instrumentation prior to shipment is acceptable. Seller and Buyer shall mutually agree upon exceptions to this requirement.

In the event a test is postponed and the test equipment has not met the requirements of the calibration frequency, it shall be permissible to start the test and, as soon as practical and no more than 45 Days after
test completion, have the test instrumentation re-calibrated. The test procedures shall define the method of correction of test results in the event the subsequent calibration determines the presence of an instrument error from the initial
calibration.

| | 4. | All primary temporary instrumentation (as detailed in Table 1) will initially require laboratory grade calibrations, defined as a high accuracy calibration in a very
controlled environment. Re-calibration or re-ranging of this instrumentation may be performed in the field upon mutual agreement between Buyer and Seller. It is understood that the Class 2 primary flow elements will not be calibrated.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | Post-test calibrations shall not be required unless the measured test data is considered suspect by any party to the test or the calibration frequency requirements have not been met
prior to the test. Post-test calibration data will only be used to adjust the measured test data if all parties to the test determine this is a valid correction.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6. | Calibration records should be made available to all parties for the instruments requiring calibration.
| | -- | ------------------------------------------------------------------------------------------------------



| | 7. | In general, it shall be considered unnecessary to apply calibration data to measured pressures. However, the calibration data will be considered for all primary temperature
measurements as identified in Table 1. Water leg corrections for pressure and differential pressure measurements shall be made.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 8. | Unless specifically stated otherwise, inspections of all flow elements will be done only if data is found to be suspect, and will be a mutual decision between all parties to the
test. If the parties to the test agree that an inspection is necessary, an inspection will most likely be completed using a borescope during a planned shutdown of sufficient duration. See section C.1 for feedwater flow discussion.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

However, the allowable deviation from rated conditions for STG exhaust pressure shall be expanded to accommodate the expected range of operation of the
condenser and cooling tower throughout the entire year. For the exhaust pressure, Seller shall submit a correction curve covering the range of expected operation for STG exhaust pressures. This correction curve will be used to correct the steam
turbine performance to reference conditions.

| | a. | Buyer shall isolate the cycle to the extent practical, and within the limits of safe operation. However, the following small leakage flows are expected to be in operation around
certain valves to ensure safe operation during an emergency situation:
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

i. Warm up steam around the cold reheat to gland
steam seal system letdown valve

ii. Warm up steam around the HP bypass valve

iii. Warm up steam around the IP bypass valve

These small flows will be assumed to be negligible. Any other identified flows will be evaluated and the performance impact shall be considered; small flows with no performance impact will be deemed negligible. These valves will be
throttled to the extent possible.



| | b. | The Sellers test procedure shall detail the plant valve line-up and other operating conditions not detailed above. The final decision to isolate any valves shall be by Buyer.
This information shall be communicated to the Seller before the commencement of the test program.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | Prior to testing, a test will be performed to quantify the total leakage from the cycle via a two hour hotwell drop test. Cycle isolation must be completed per the agreed upon cycle
isolation list provided in the Sellers test procedure prior to commencement of this test.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The total measured
Unaccounted for Cycle Losses flow rate should be less than or equal to 0.25% of test throttle flow rate at full load. If it is determined that the total Unaccounted for Cycle Losses flow rate is greater than 0.25%, efforts will be made to locate and
fix the additional cycle losses, unless the parties mutually agree otherwise. The final Unaccounted for Cycle Losses flow rate will be calculated in the following manner;

Unaccounted for Cycle Losses = Measured Cycle Losses Accounted for Cycle Losses.

If the Unaccounted for Cycle Losses are still greater than 0.25% after exhausting all reasonable efforts to determine the source of the additional cycle
losses, both the Buyer and Seller need to come to a mutual agreement to continue the test program with a higher than expected Unaccounted for Cycle Loss (> 0.25%). If agreement is reached, the above equation for Unaccounted for Cycle Losses will
be used.



| | 6. | All Unaccounted for Cycle Losses will be used in the adjustment of main steam flow to the steam turbine in the acceptance test calculations.

STG PERFORMANCE TEST PROTOCOL



Option 1(N2 packing is for HP-IP opposed flow turbines only)

The N2 internal packing flow will be determined by a N2 Inference Method test conducted by the Seller and witnessed by the Buyer. The excerpt
from the Steam Turbine Test Procedure concerning N2 Flow is shown below.

N2 Packing Leakage Test

In order to determine the actual HP turbine exhaust flow and the true IP turbine efficiency, the N2 packing leakage must be determined. The N2 packing
leakage is the steam which leaks from the first stage of the HP turbine to the IP turbine bowl along the N2 shaft packing. The steam turbine is designed to pass a given amount of steam flow to cool the first reheat stage during
operation. Depending on the packing clearances, and stage pressures, this flow may be somewhat greater than or less than the design flow on the contract heat balances. Determination of this flow reduces the test uncertainty associated with the steam
turbine performance.

The method used to determine the N2 packing leakage test is commonly referred to as the Booth-Kautzmann
method, or the Temperature Inference Method. This test requires that the unit operate at base load or near base load at different combinations of inlet temperatures to the HP and IP sections of the steam turbine. Typically, a test run is
conducted at a minimum of three different temperature conditions as outlined below.



| |  |  | Superheat and Reheat Temperatures Equivalent
| | - |  | --------------------------------------------



| |  |  | Superheat Temperature. Approx. 50° F greater than Reheat Temperature.
| | - |  | ---------------------------------------------------------------------



| |  |  | Reheat Temperature Approx. 50° F greater than Superheat Temperature.
| | - |  | --------------------------------------------------------------------

The temperature splits described above can usually be achieved by using the spray flows to attemperate the superheat and reheat steam temperatures.

Typically, in order to achieve the desired temperature split, it is recommended to conduct N2 packing test at approximately 75%-80% load. The duration of
each of these test runs should be at least 30 minutes, but will likely require much longer amount of time in between runs to change the superheat and reheat temperatures and achieve steady state conditions. No cycle isolation is required for these
test runs.

The boiler should be operated at steady load during entire N2 packing test. The N2 packing test will be conducted at the same
time as the bench mark test (if applicable). The test should be conducted at the highest attainable load, but no lower than 75% of the guaranteed load. The test should be conducted with the control valves in the wide-open position for all stop and
intercept/ control valves.

Option 2

The N2 packing leakage shall be calculated at as fixed percentage of HP throttle flow, based upon conditions at the reference conditions. The fixed percentage can be calculated from the Seller supplied heat balance at
the guarantee condition.



| | 8. | Turbine throttle steam flow shall be determined as the boilers measured feedwater flow plus any additional spray water flow minus any unaccounted-for leakages in the steam
cycle.

| | G. | Data Collection and Reduction
| | -- | -----------------------------



| | 1. | All test data collected during the test shall be provided to Buyer as early as reasonably possible after the test. When data is available electronically, electronic files shall be
provided to all parties. If additional instruments have been installed by Seller for diagnostic purposes, then such data shall be made available to Buyer by Seller, unless Seller determines that such data is proprietary.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Data which appears to be in error may be rejected after mutual agreement between the Buyer and Seller.
| | -- | ------------------------------------------------------------------------------------------------------



| | H. | Test Tolerance and Test Uncertainty
| | -- | -----------------------------------



| | 1. | The final test tolerance used to determine whether Seller has met guaranteed performance shall be based on a pre-determined commercial test tolerance. The commercial test tolerance
shall be as defined in Section 5, Appendix 4, Clause 7, B, d.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | A pre-test uncertainty calculation shall be performed to establish an estimate of the test uncertainty. A post-test uncertainty calculation shall not be performed if no deviation
from the conditions specified herein are found, except those caused by Seller.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | If there are no significant deviations from the assumptions made in this document, then the test tolerance specified in Section 5, Appendix 4, Clause 7, B, d will be used as
the test tolerance for evaluating the Sellers performance against the performance guarantees. The test tolerance specified in Section 5, Appendix 4, Clause 7, B, d will be the minimum test tolerance to be applied as a band around the
measured Equipment Performance Guarantee values.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Should one or more of the provisions agreed upon herein not be incorporated
by Buyer, that in the reasonable opinion of the Buyer and Seller, materially increase the test uncertainty above the pre-test uncertainty estimate, then a post test uncertainty calculation shall be performed. The test tolerance shall be increased
above the commercial test tolerance defined in Section 5, Appendix 4, Clause 7, B, d to account for the test uncertainty increase between the pre-test and post-test uncertainty calculations.

However, if Buyer and Seller agree that there are adequate reasons for the test tolerance to be increased for reasons attributable to Buyer, and at the
same time there are aspects of the test that are being performed more accurately than specified in this document that result in a reduction in test uncertainty, then these provisions shall also be considered. The test provisions that lead to higher
than expected test uncertainty shall be offset against test provisions that lead to lower than expected test uncertainty. The net difference between these offsetting differences shall be used to adjust the test tolerance, provided that the ultimate
test tolerance value will not be lower than the value specified in Section 5, Appendix 4, Clause 7, B, d.

All test uncertainty
calculations shall be determined in general accordance with ASME PTC 19.1  1998.

|1.0 | General - Liquidated Damages (LDs) Reasonable
|--- | ---------------------------------------------

The
Parties agree that Buyer would be damaged by Sellers failure to meet the required dates (Guaranteed Milestone Dates) set forth in Articles 2, 3 and 4 of this Appendix 5 (including any failure to achieve Substantial Completion by
the date which is ninety (90) Days prior to the Guaranteed Substantial Completion Date which is attributable to Seller) and that Buyers actual damages in any such event would be extremely impracticable or impossible to calculate.
Accordingly, the Parties agree that Sellers liability to Buyer for failure to achieve the specified dates shall be determined by and limited to amounts as specified below, which Seller agrees to pay to Buyer in such event as liquidated damages
and not as a penalty.

The Parties, having negotiated in good faith for such specific liquidated damages and having agreed that the amount
of such liquidated damages is reasonable in light of the anticipated harm caused by the breach or fault related thereto and the difficulties of proof of loss and inconvenience or nonfeasibility of obtaining any adequate remedy, are estopped from
contesting the validity or enforceability of such liquidated damages.

If any sum specified as liquidated damages fails as liquidated
damages for any reason, then Seller shall nonetheless be liable to pay general damages in respect thereof, provided that such general damages shall not exceed the subcap applicable to any liquidated damages that would have been payable in such
circumstances.

Except as provided herein, each item of liquidated damages appearing in Articles 2, 3 and 4 below shall apply separately and
independently of every other item of liquidated damages appearing in this Appendix 5. To the extent funds withheld by Buyer are not sufficient to pay any and all liquidated damages arising under this Agreement, Seller shall pay such liquidated
damages upon demand, after receipt of Buyers claim and invoice.

Payment of liquidated damages shall not relieve Seller from its
obligation to carry out and complete the Work in accordance with this Agreement and/or from any other duties, obligations or responsibilities Seller may have under this Agreement and, accordingly, shall not prejudice Buyers rights in the event
of the failure of Seller to comply with any such obligations, subject to the provisions of Section 5 (Special Conditions) Clause SC-30 (Limitation of Liability).



|2.0 | Drawings, Documentation and Engineering Data
|--- | --------------------------------------------



|2.1 | Drawings and engineering data shall be submitted by Seller in accordance with Section 2 (Technical Specifications) Appendix B of Material Requisition (Document Submittal
Requirements (DSRs)), shall be complete and of a professional quality. Guaranteed Document Milestone Dates shown in the DSR are the dates such drawings or other documents are to be received by Buyer at the address
stipulated in Section 3 (Drawings and Data). Seller may transmit documents by the most expedient means available including electronic transmission, provided the date Buyer receives such transmission is no later than the relevant Guaranteed
Document Milestone Date. Where electronic transmission has been made, Buyer shall receive one corresponding paper copy within seven (7) Days of the electronic transmission.

|2.5 | In the event that a given Item Number as shown in Appendix B Column No 1 includes more than one drawing/document, then Document Delivery LDs for late submittals shall
only be assessed to the individual Item Number as a whole and the breakdown of drawing/document information on the drawing list shall not be treated as separate submittals for purposes of calculating Document Delivery LDs.
For the avoidance of doubt Document Delivery LDs shall be assessed against the delay in submission of the last document submitted within a milestone group/ Item Number.

|2.6 | Additionally, for purposes of assessing Document Delivery LDs, any document submittals, which receive status code 1, 2 or 4 shall be deemed to have been submitted by Seller. If
these status code 1, 2 or 4 documents are subsequently revised by Sellers changes causing rework by Buyer, such rework shall be charged to Sellers account in accordance with Section 5 (Special Conditions) Clause SC-11 (Backcharges).

|2.7 | If any document submittal receives a status code 3 then, for the purpose of assessing the liability of Seller to pay Document Delivery LDs, such document submittal shall be deemed
not to have been received by Buyer until a revised or replacement document is received which receives a status code 1, 2 or 4 review stamp, or unless or until Seller has otherwise provided the necessary information in another format acceptable to
Buyer. As stated in Section 3 (Drawing and Data Requirements), any submittal rejection does not relieve Seller of any schedule commitments. Subject to the requirements of Article 2.2 above, Document Delivery LDs for any document receiving a
status code 3 review stamp shall begin to accrue on the earlier of (a) the date on which Seller is notified of the status code 3 review stamp for such document, or (b) fifteen (15) Days following the date of Buyers receipt of
such document.

Equipment prevent its operation, as required, to support Buyers start-up and commissioning of the Facility and its component equipment and systems (including Performance Test activities for the achievement of Substantial Completion) or
(c) the Equipment is unable to operate in support of the Performance Tests for Substantial Completion, and to the extent any of the foregoing causes delay in achieving Substantial Completion beyond the date that is ninety (90) Days prior
to the Guaranteed Substantial Completion Date (as such date may be extended from time to time under the EPC Contract), then (subject to provisions of Article 4.2 and the qualifications set forth below), Seller shall pay liquidated damages

|4.3 | Such seventy-five (75) Access Day period shall be reduced by the number of Days that the cumulative impact of Equipment Delivery Delay(s) causes Turbine Roll to be delayed. In
addition, in the event that all other equipment and systems in the Facility are ready to support Turbine Roll and a defect(s) or deficiency(ies) in the Equipment is the primary cause of a delay in the Turbine Roll date, such seventy-five
(75) Day period also shall be reduced one Day for each Day of delay caused primarily by such defect(s) or deficiency(ies) in the Equipment as aforesaid.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.4 | If Buyer is unable to provide such period of seventy-five (75) Access Days (or such lesser period as provided in Article 4.3 above), then (notwithstanding that the date for
Guaranteed Substantial Completion Date may have occurred) Days of delay will not be allocated to the Seller (hence no liability to the Buyer for Substantial Completion LDs shall apply) until Buyer has provided it with seventy-five (75) Days (or
such lesser period as provided in Article 4.3 above) for the start up and commissioning of the Equipment from the Turbine Roll date.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.5 | For the purposes of calculating the number of Access Days for the start up and commissioning of Equipment, if Seller has access to the Equipment to perform start up related
activities required for operation and the achievement of Substantial Completion, that Day shall be counted as an Access Day for the start up and commissioning of Equipment.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.6 | An Access Day shall be any day during which the Equipment is available for performance of check out, balancing, tuning (including part load and integrated base, or other
work start-up related activities) required so that Equipment will support the achievement of Substantial Completion or the Performance Guarantees. In the event that conflicting Facility activities or circumstances arise that prevent the performance
of the necessary startup related activities in the order and manner reasonably required by Seller, and that event causes a delay for that Day, an Access Day shall not have occurred. Notwithstanding the above, there shall be an Access Day if Seller
has access to the Equipment, the required lubricants, operating supplies and third party interconnections are available, Owners operators are available as necessary to operate the Equipment as required and Buyers craft labor are
available as agreed to support Sellers startup activities.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.7 | For the avoidance of any doubt, if Buyer fails to make the Equipment available as contemplated by the preceding paragraph that Day will not be counted as an Access Day for the start
up and commissioning of Equipment. Conversely, if Buyer makes the Equipment available as contemplated by the preceding paragraph and Seller elects not to perform startup activities, that Day will be counted as an Access Day for the start up and
commissioning of Equipment.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.8 | It shall be understood that all Parties will actively participate in the coordination and scheduling of startup related activities to achieve Substantial Completion in an organized,
effective and efficient manner.
