 (b) In respect of each six (6) Month period starting on the 1st of January and
the 1st of July respectively of each Year, other than the first such six (6) Month period of the Effective Term, the amount referenced in Section 7.3(a) shall be determined as the highest Total Monthly Payment amount (calculated on the
basis that all Units had been available at their Target Availability, had been dispatched and operated at 90% of this level and one cold Start Up of each Unit had been performed) that would have been due to the Owner from the Buyer in respect of any
of the previous six (6) Months. For the first six (6) Months of the Effective Term, the amount referenced in Section 7.3(a) shall be determined as an estimate of the Total Monthly Payment amount (calculated on the basis that all Units
will be available at their Target Availability, will be dispatched and operated at 90% of this level and one cold Start Up of each Unit will be performed) in respect of the first Month of the Effective Term. 

(c) In the event that the Buyer is required to replace, or desires to replace, any bank guarantee, irrevocable letter of

7.4 Cost Savings 
 (a) If, during the Effective Term of this Arrangement, a decision is taken that the Whitewood Mine should be closed, either the Owner or the Buyer may, within 60 days of such decision,
request the commissioning of an independent study (the “Mine Study”) to be carried out with respect to the potential saving that could be realized from the deployment of the Marion 8200 Dragline (together with its associated equipment),
presently located at the Whitewood Mine, at the Highvale Mine. 
 (b) The other Party may agree on the
possibility and level (if positive) of cost savings, in which case the proposed changes shall be implemented and the Parties

 Sundance C
Power Purchase Arrangement 
 shall be compensated as set out hereunder. Lacking such agreement, the study the
Mine Study shall be commissioned and undertaken by an independent and reputable mining engineering consultant, generally accepted as skilled in the area of coal mining equipment deployment, agreed to by both Parties. The Mine Study shall provide an
ex ante forecast of all annual fixed (those costs which are constant regardless of the level of coal production) and variable (those costs which vary with the level of coal production) cost savings that would be expected to be achieved by the
deployment of the Marion 8200 Dragline at the Highvale Mine for each Year remaining in the Arrangement at the time the Mine Study is undertaken. An indexation mechanism shall be determined for the fixed coal costs and the variable coal costs set out
in the Mine Study. All cost savings would be calculated using then existing costs as the base numbers. In calculating such savings, the Mine Study shall incorporate a forecast of total coal production at the Highvale Mine in each Year then remaining
in the term of the Arrangement, such forecast to be developed by agreement or a mutually acceptable independent expert generally accepted as skilled in the area of coal production. 

(c) The Parties shall co-operate in the carrying out of the Mine Study and take all necessary reasonable steps to ensure
that it is completed in a timely way. 
 (d) In the event that no potential savings are identified by the Mine
Study or any savings which are identified are not material in the opinion of the consultant preparing the Mine Study, the full cost of the Mine Study shall be borne by the Party which requested it but in all other cases the Mine Study shall be paid
for by the Owner and the first call on any savings in mining costs shall be used to pay the Owner’s costs in respect of the Mine Study. 
 (e) If the forecast savings are material, they shall be shared equally by the Owner, as to one half, and the group consisting of each buyer or holder of a power purchase arrangement,
financial instrument or financial settlement pursuant to Part 4.1 of the Act with respect to the Keephills plant and the Sundance plant, or any part thereof, as to the other half, using the ex-ante forecasts of fixed cost savings and variable cost
savings contained in the Mine Study and not the actual results achieved in each Year. Each such buyer’s or holder’s share shall be pro-rata to the sum of all of its Deemed Annual Coal Consumption (ACUuy), as determined in Schedule E in
respect of the latest Year for which such values have been determined or, in respect of the first Year of the Effective Term, the values of ACUuy that would have been determined if the Units were dispatch at their Target Availabailities (TAuy), all
calculated in accordance with the power purchaser arrangement, financial instrument or financial settlement applicable to such buyer or holder 
 (f) At the commencement of each Year following the release of the Mine Study, the Owner shall prepare a bona fide estimate of the total cost savings which are expected for such Year and
provide such figure to the Buyer. The Buyer shall thereupon be entitled to deduct its proportionate share of such amount by way of 12 equal installments from each of the monthly payments it makes to the Owner

 in such Year. Within 60 days after the end of such Year, the Owner shall calculate
the total cost savings in accordance with the mechanism set out in Section 7.4(g) and whatever adjustment is required so that the Parties shall share those total cost savings as set out in Section 7.4(e), shall be paid forthwith by the
Party owing such adjustment payment. 
 (g) The mechanism for calculating the total cost savings for a Year is as
follows: 
 (i) The quantum of the fixed costs savings for such Year shall be equal to the ex-ante forecast of
fixed savings identified in the Mine Study for such Year. 
 (ii) The quantum of the variable cost savings for
such Year shall be calculated by adjusting the quantum of the ex-ante forecast identified in the Mine Study for such Year by the following formula: 
 variable cost savings = quantum of ex ante variable forecast of cost savings x (Actual production/Expected production) 

where: 
 Actual production = the actual coal production for such Year (expressed in tonnes); and 
 Expected production = the coal production for such Year as set out in the Mine Study (expressed in tonnes). 
 (iii) The fixed cost savings determined in accordance with Section 7.4(g)(i) shall be escalated to such Year using the same indexation mechanism determined for the fixed cost savings
in the Mine Study. The variable cost savings determined in accordance with Section 7.4(g)(ii) shall be escalated to such Year using the same indexation mechanism as determined for the variable coal costs in the Mine Study. 

(iv) The sum of the fixed cost savings and variable cost savings, as escalated in accordance with
Section 7.4(g)(iii), equals the total cost savings for the Year. 
 ARTICLE 8 COSTS 

8.1 Change in Costs

 ARTICLE 9 INSURANCE 

9.1 Insurance Coverage 
 (a) The Owner shall, at all times during the Effective Term, hold property (including boiler and machinery) insurance and commercial general liability insurance in respect of the Units and
the Plant. Notwithstanding the requirements of Section 8.2, the Owner shall make all reasonable efforts to procure such insurance on the best financial terms available to it having regard to the totality of its insurance requirements for all
its business operations. The terms in respect of, but not limited to, exclusions and coverage limits of the insurance coverage that the Owner is required to hold pursuant to this Section 9.1, shall not be materially different in terms of
coverage or exclusions to those in the policies held by the Owner in force as at 9 July 1999, with the exceptions that: 
 (i) the deductible with respect to each property damage occurrence shall be not less than $250,000 (indexed in respect of each year of the Effective Term by the year over year change in
the Consumer Price Index taking the value published in respect of December 1998 as a base value); and 
 (ii) the
insurance coverage limits applicable in each year shall be indexed by the year over year change in the Consumer Price Index taking the value published in respect of December 1998 as a base value. 

(b) The annual premiums incurred by the Owner in respect of such insurance coverage shall be allocated to each Unit in
accordance with the provisions of this Section 9.1. 
 (c) Not later than each anniversary of the first day
of the Effective Term, the Owner shall, acting reasonably, as part of its obligation to determine the Monthly Capacity Payment in accordance with Schedule C, determine the total insurance premiums that are to be allocated to all of the units (other
than hydro units) it owns that: 
 (i) were subject to a power purchase arrangement or financial settlement
pursuant to Part 4.1 of the Act, as at the first day of the Effective Term; and

 (ii) have not been decommissioned (whether or not any power purchase arrangement or
financial settlement pursuant to Part 4.1 of the Act is still in effect with respect to these units). 
 (d) The
units identified in (c) above are herein defined as the “Candidate Units”. Each of the Units shall be allocated a pro-rata share of the insurance premiums referenced in 9.1(c) above based upon its Committed Capacity as a proportion of the
committed capacity (as defined in the power purchase arrangement or financial settlement pursuant to Part 4.1 of the Act) of all of the Candidate Units. For the purposes of this calculation, a Candidate Unit in respect of which no power purchase
arrangement or financial settlement is in effect at the time such calculation is made shall be considered to have a committed capacity equal to the committed capacity that it had as at the day before such power purchase arrangement or financial
settlement ceased to apply to that unit. The pro-rata share of the insurance premiums for each of the Units as calculated above shall be incorporated into the Monthly Capacity Payment in accordance with Schedule C. 

(e) In the event that the insurance specified in Section 9.1(a) is not available, the terms (including those with respect
to exclusions, limits, and deductibles) of available insurance are materially different from those specified in Section 9.1(a) or any circumstance has changed which reasonably alters the need for the type, level or terms of the coverage specified in
Section 9.1(a), the Owner may, acting reasonably and in accordance with Good Operating Practice, modify the type, level or terms of the insurance coverage to be held by the Owner with respect to the Units and the Plant and the provisions of this
Section 9.1 shall apply mutatis mutandis. 
 (f) The Owner shall provide the Buyer or the Balancing Pool with
certificates of insurance evidencing the insurance required by this Section 9.1 as the Buyer or the Balancing Pool may from time to time reasonably request. 
 9.2 Insurance Proceeds 
 If a Unit is totally or
partially destroyed and if the Owner is required pursuant to the terms of Section 15.1 to repair, replace, rebuild or restore the Unit, the Owner shall use the proceeds of the insurance referred to in Section 9.1 together with such other amounts as
may be necessary to meet such obligations.

Statement. 
 ARTICLE 12 OPERATING CHARACTERISTICS 

12.1 Changes in Operating Characteristics 
 All changes to the Operating Characteristics of the Units shall be communicated by the Owner to the Buyer in accordance with Schedule H. Changes to such Operating Characteristics (other
than in respect of a Settlement Period in which a Party’s obligation to perform or comply with an obligation under this Arrangement with respect to the Operating Characteristics is suspended pursuant to Section 14.1 or Section 2.7) shall give
rise to the payment to the Buyer by the Owner of the amounts determined in accordance with the provisions of Schedule H. 
 ARTICLE 13 LIABILITY AND INDEMNIFICATION 13.1 Indemnification 
 (a) Each Party (each an “Indemnitor”) shall indemnify and hold harmless the other Party and such other Party’s Affiliates, directors, officers, partners, employees,
contractors, subcontractors, agents and representatives thereof (individually and collectively called an “Indemnitee”) from and against all losses, damages and liabilities suffered by the Indemnitee and all judgments, fines, penalties,
charges, settlement amounts, costs, expenses and reasonable legal fees (on a solicitor and own client basis, including reasonable disbursements) incurred by the Indemnitee in connection with any causes of action, action, claim, suit, inquiry,
proceeding, investigation or appeal therefrom, arising in connection with the acts or omissions to act of such Indemnitor which are a result of such Indemnitor’s fault, negligence, or breach of its obligations under this Arrangement.

 (b) In the event that any Indemnitee desires to assert its right to indemnification from an Indemnitor
required to indemnify such Indemnitee under this Section 13.1, the Indemnitee shall give the Indemnitor prompt notice of the claim giving rise thereto (a “Claim”), which shall describe the Claim in reasonable detail and shall indicate the
estimated amount, if practicable, of the indemnifiable loss that has been or may be sustained by the Indemnitee. The failure to promptly notify the

 Indemnitor hereunder shall not relieve the Indemnitor of its obligations hereunder,
except to the extent that the Indemnitor is actually and materially prejudiced by the failure to so notify promptly. 
 (c) The Indemnitor shall have the right to participate in or, by giving written notice to the Indemnitee to elect to assume the defence of a Claim in the manner provided in this Section
13.1 at the Indemnitor’s own expense and by the Indemnitor’s own counsel (reasonably satisfactory to the Indemnitee), and the Indemnitee will cooperate in good faith in such defence. 

(d) In the event the Indemnitor desires to assume the defence of a Claim, it shall deliver to the Indemnitee written
notice of its election within 30 Days following the Indemnitor’s receipt of the Indemnitee’s notice of such Claim. Until such time as the Indemnitee shall have received such notice of election, it shall be free to defend such Claim in any
reasonable manner it shall see fit and in any event shall take all actions necessary to preserve its rights to object to or defend against such Claim and shall not make any admission of liability regarding or settle or compromise such Claim. If the
Indemnitor elects to assume such defence, it shall promptly reimburse the Indemnitee for all reasonable expenses theretofore incurred by it in connection with such Claim but it shall not be liable for any legal expenses incurred by the Indemnitee in
connection with the defence thereof subsequent to the time the Indemnitor commences to defend such Claim. 
 (e)
Without the prior consent of the Indemnitee, the Indemnitor shall not make any admission of liability regarding or enter into any settlement or compromise of or compromise any Claim which would lead to liability or create any financial or other
obligation on the part of the Indemnitee for which the Indemnitee is not entitled to full indemnification hereunder or for which the Indemnitee has not been fully released and discharged from further liability or obligations. Similarly, the
Indemnitee shall not make any admission of liability regarding or settle or compromise such Claim without the prior consent of the Indemnitor. If a firm offer is made to settle a Claim without leading to liability or the creation of a financial or
other obligation of the part of the Indemnitee for which the Indemnitee is not entitled to full indemnification hereunder or for which the Indemnitee has not been fully released and discharged from further liability or obligations, and the
Indemnitor desires to accept and agree to such offer, the Indemnitor shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within 5 Days after receipt of such notice or such shorter period
as may be required by the offer to settle, the 
 Indemnitor may continue to contest or defend such Claim and, in
such event, the maximum liability of the Indemnitor in relation to such Claim shall be the amount of such settlement offer, plus reasonable costs and expenses paid or incurred by the Indemnitee up to the date of such notice. 

(f) The Indemnitee shall use all reasonable efforts to make available to the Indemnitor or its representatives all books,
records, documents and other materials and shall use all reasonable efforts to provide access to its employees

 and make such employees available as witnesses as reasonably required by the
Indemnitor for its use in defending any Claim and shall otherwise co-operate to the fullest extent reasonable with the Indemnitor in the defence of such Claim. The Indemnitor shall be responsible for all reasonable expenses associated with making
such books, records, documents, materials, employees and witnesses available to the Indemnitor or its representatives. 
 (g) The right of any Indemnitee to the indemnification provided herein shall be cumulative of, and in addition to, any and all rights to which such Indemnitee may otherwise be entitled by
contract or as a matter of law or equity and shall extend to its or his heirs, successors, assigns and legal representatives. 
 (h) If the Indemnitor has undertaken the defence of a Claim and: 
 (i) if there is a reasonable expectation that such Claim may materially and adversely affect the Indemnitee other than as a result of money damages or other money payments, or the
Indemnitee or Indemnitees may have legal defences available to it or them that are different from or additional to the defences available to the Indemnitor; then the Indemnitee shall have the right, at its own cost and expense, to defend such Claim;
and 
 (ii) if the Indemnitor shall not have employed counsel reasonably satisfactory to the Indemnitee, the
Indemnitee shall nevertheless have the right, at its own cost and expense, to defend such Claim. 
 13.2
Consequential Loss 
 Notwithstanding any other provision of this Arrangement, neither Party shall be liable to
the other Party or its Affiliates, directors, officers, partners, employees, contractors, subcontractors, agents and representatives thereof for any reason (including negligence on the part of the first Party or any Person for whose acts it is
responsible, and howsoever a head of damage may be formulated) in respect of any consequential or indirect damages of any nature whatsoever including loss of use, loss of revenue, loss of profit, loss of contract or loss of goodwill or any other
loss or damage of an indirect or consequential nature suffered by the other Party or its Affiliates, directors, officers, partners, employees, contractors, subcontractors, agents and representatives thereof in connection with this Arrangement other
than as specifically provided for in Schedules D, H and K to this Arrangement. 
 13.3 Compensation for Failure
to Provide Generation Services 
 The Buyer shall be fully compensated for any failure by the Owner for any
reason whatsoever to provide Generation Services to the Buyer in accordance with this Arrangement, including any degradation whatsoever in the Committed Operating Characteristics of the Units for any reason, through the Monthly Incentive Payments
and the Monthly Operating Characteristics Penalty Payments. Accordingly, payment of the Monthly Incentive Payment and the Monthly Operating Characteristics Penalty Payment shall be the sole and exclusive remedy for any such failure by the Owner and
the Buyer

 shall not be entitled to make any other claim against the Owner including a claim
under Section 13.1, and shall not have any other remedy at law or in equity, for any losses, costs, expenses, damages or other liabilities of any nature or kind that may be incurred or suffered by the Buyer in connection with any such failure, and
notwithstanding any other provision of this Arrangement, the Owner shall not be in default under this Arrangement in connection with any such failure unless such failure results from the Owner’s willful act or omission. 

13.4 Duty to Mitigate 
 Each Party has a duty to mitigate damages and shall use all reasonable efforts to minimize any losses, costs, expenses, damages or other liabilities it may incur as a result of the other
Party’s performance or non-performance of this Arrangement, but for greater certainty, neither Party shall have any duty to mitigate damages or losses for which this Arrangement provides specific compensation by way of the Monthly Incentive
Payments, Monthly Operating Characteristics Penalty Payments or any Termination Payments unless otherwise stated. 
 ARTICLE 14 FORCE MAJEURE 
 14.1 Relief for Force
Majeure 
 If either Party is unable, wholly or in part, to perform or comply with any obligation hereunder, and
if such inability shall have been occasioned by or as a consequence of any event of Force Majeure, the obligations of such Party, insofar only as its obligations are affected by the event of Force Majeure, shall be suspended for so long as the event
of Force Majeure continues to prevent the performance of or compliance with such obligation and for such time thereafter as such Party may reasonably require to fulfill such obligation. 

14.2 Notice and Efforts to Continue 
 If either Party relies on the occurrence of an event of Force Majeure as a basis for claiming suspension of an obligation under this Arrangement, such Party shall: 

(a) provide prompt notice to the other Party and the Balancing Pool of the event or condition being relied upon as an
event of Force Majeure, including its expected duration and the probable impact on the performance of or compliance with its obligations hereunder; 
 (b) exercise all reasonable efforts to continue to perform or comply with its obligations hereunder; 
 (c) exercise all reasonable efforts to mitigate or limit the effect of the event of Force Majeure; and

 (d) provide prompt notice to the other Party and the Balancing Pool upon the
cessation of the event of Force Majeure. 
 14.3 Labour Disturbances 

Notwithstanding any other provision of this Arrangement, the settlement of strikes, lockouts or other labour disputes or
industrial disturbances shall be entirely within the discretion of the Party involved therein and that Party may make settlement thereof at such time and on such terms and conditions as it may deem to be appropriate and the failure to make such a
settlement shall constitute a cause beyond the reasonable control of that Party. 
 14.4 Effect of Force Majeure

 During any period in which the Owner’s obligations to perform or comply with an obligation under this
Arrangement are suspended pursuant to Section 14.1, the Monthly Capacity Payment shall be reduced as provided for in Schedule C to reflect the availability of Committed Capacity of each Unit during such Month. The Owner shall be entitled to payment
from the Balancing Pool of the difference, if any, between the Provisional Capacity Payment and the Monthly Capacity Payment for such Month. 
 14.5 Buyer’s Force Majeure 
 During any event
existing on the IES which is caused by any event or occurrence of the character herein defined as constituting Force Majeure, and which renders the Buyer unable, in whole or in part, to take delivery of Electricity (and for the purposes of
calculations made in the Schedules to this Arrangement such an event shall be classified as an event of Force Majeure), the Monthly Capacity Payment for a Month shall be reduced as provided for in Schedule C to reflect such inability of the Buyer
and the provisions of Section 14.4 shall apply mutatis mutandis. 
 14.6 Termination for Force Majeure

 Subject to Section 15.4, but notwithstanding any other provision of this Arrangement, if an event of Force
Majeure relieves the Owner of all or substantially all its obligations to make available Committed Capacity or to deliver Electricity and System Support Services from any Unit hereunder: 

(a) for any period of six (6) consecutive Months; or 

(b) where both Parties agree that such Force Majeure event will have such an effect for six (6) consecutive months; or

 (c) where both Parties agree that such Force Majeure event will have such an effect beyond the end of the
Effective Term; 
 then the Buyer may terminate this Arrangement in whole but not in part.

15.1 Total or Partial Destruction 
 If any Unit or the Plant is totally or partially damaged or destroyed by any cause whatsoever, the Owner shall, notwithstanding any other provision of this Arrangement, promptly inform the
Buyer, in writing, of such event. In addition the Owner shall, as soon as it is reasonable inform the Buyer of the likely period for which such Unit or the Plant will be unavailable for operation. The Owner shall repair, replace, rebuild or restore
such Unit or the Plant with all reasonable diligence consistent with Good Operating Practice to at least as good condition or state of repair as it was prior to that damage or destruction; provided that if this Arrangement is terminated in whole or
in part under the terms of Sections 15.2 or 15.3, then the Owner shall not be obligated to repair, replace, rebuild or restore such Unit or the Plant. In the event that this Arrangement is not terminated in respect of such Unit, the Owner shall
regularly report to the Buyer, in writing, of the progress of the repair work, including an estimate of when the work will be completed . 
 15.2 Owner’s Termination for Destruction

If any Unit or the Plant identified under the terms of Section 15.1 is damaged or destroyed to such an extent that a Unit or the Plant is incapable of generating Electricity and the Owner reasonably determines, after taking into account the age and
condition of such Unit or the Plant, that such Unit or the Plant, as the case may be, cannot be economically repaired, replaced, rebuilt or restored (taking into account both the Owner’s and the Buyer’s expected future income from the
repaired, replaced, rebuilt or restored Unit or Plant and the cost thereof, net of any insurance proceeds), it shall, by giving written notice to the Buyer and the Balancing Pool within sixty (60) Days after such damage or destruction has occurred,
inform the Buyer and the Balancing Pool of the Owner’s determination and seek the Buyer’s agreement to this determination. Termination in respect of less than the whole Plant shall additionally require the agreement of the Balancing Pool
if the Balancing Pool is to pay a termination amount in accordance with Schedule L. 
 (b) If the Buyer and, if
the Balancing Pool’s agreement is required, the Balancing Pool agree with the Owner’s determination or fail to dispute the determination within ten (10) Business Days after notice of the determination is given, this Arrangement will
immediately terminate in respect of such Unit or the Plant as the case may be. 
 (c) If the Buyer (or, as the
case may be, the Balancing Pool) disputes the Owner’s determination within such ten (10) Business Days, the dispute shall be resolved in accordance with Article 19 (which determination shall be binding upon the Balancing Pool in respect of
termination for less than all of the Units).

 (d) If a dispute arises between the Owner and the Balancing Pool with respect to
the Owner’s determination to terminate and it is determined pursuant to Article 19, taking into account the factors referred to in this Section 15.2, that such Unit or Units, as the case may be, can be economically repaired, replaced, rebuilt
or restored, the Owner, by way of notice to the Buyer and the Balancing Pool (within ten (10) Days of resolution of such dispute pursuant to Article 19), shall have the opportunity to withdraw its determination with respect to less than all of the
Units in which case this Arrangement will not terminate. 
 (e) If it is determined pursuant to Article 19,
taking into account the factors referred to in this Section 15.2, that such Unit or the Plant, as the case may be, cannot be economically repaired, replaced, rebuilt or restored, this Arrangement shall immediately terminate in respect of such Unit
or the Plant, as the case may be. 
 15.3 Buyer’s Termination for Destruction 

In respect of any Unit or the Plant identified under the terms of Section 15.1 the Buyer may terminate this Arrangement in
whole but not in part: 
 (a) by giving written notice to the Owner within thirty (30) Days after such damage or
destruction has occurred, if it reasonably expects that the Unit or Plant will be incapable of generating Electricity either for a date not less than six (6) Months from the date damage or destruction or for the balance of the Effective Term; or

 (b) if a period of six (6) Months has elapsed since the date of damage or destruction and the Unit or Plant is
not fully or substantially operational and the Buyer has, by having given written notice to the Owner within thirty (30) Days after such damage or destruction has occurred, informed the Owner of the Buyer’s desire to so terminate under the
terms of this Section 15.3.(b). 
 15.4 Termination Rights 

If any Unit or the Plant is damaged or destroyed, whether or not due to an event of Force Majeure, the Buyer’s rights
with respect to termination are set out in this Article 15, and the provisions of Section 14.6 shall not apply. 

15.5 Rights and Obligations following Termination for Destruction 

The Parties acknowledge that any termination pursuant to Sections 15.2 and 15.3 shall not affect any rights or obligations
which may have accrued prior to such termination and shall not affect the continuing obligations of each of the Parties hereunder. 
 15.6 Payments on Termination for Destruction 
 If
this Arrangement is terminated in respect of a Unit or all Units under this Article 15, then the payments among the Parties and the Balancing Pool shall be those determined according to the rules set out in Schedule L. Payment of such amount shall
fully compensate the Buyer for the termination of this Arrangement prior to the expiry of the

 The Plant and the Units shall be and remain the sole and exclusive property of the Owner or its permitted
assignees pursuant to Article 18, and nothing in this Arrangement is intended to create, or shall create, in favour of the Buyer any legal or beneficial ownership or interest in the Units or in the Plant of any nature whatsoever. For the avoidance
of doubt, it is hereby agreed and declared that the provision of Generation Services confers only a right to such Generation Services upon and subject to the terms and conditions of this Arrangement. The Owner’s obligation to provide Generation
Services shall not constitute the dedication of any Unit or the Plant or any part thereof to the Buyer, and shall not confer upon the Buyer any rights or powers regarding the availability, operation, maintenance, repair or dispatch of the Unit or
the Plant save as expressly provided in this Arrangement. 
 16.2 No Partnership 

The rights, duties, obligations and liabilities of the Parties hereunder shall be separate and not joint or collective,

 (a) If either Party is in material default in respect of any of its obligations under this Arrangement as listed in Sections 17.1(b) and 17.1(c), or is in default of its obligations to pay
any amount due to the other Party hereunder, then the other Party may, after giving not less than seven (7) Days prior written notice (either personally delivered or given by fax) of same, discontinue the performance of its obligations under this
Arrangement immediately upon the expiry of such notice period until such time as the Party in default is no longer in default in respect of any of such obligations, provided that in the case where such default cannot

 reasonably be remedied within such 7 Day notice period, the other Party shall not
be entitled to discontinue performance of its obligations under this Arrangement unless and until the Party in default fails to proceed within such 7 Day notice period and thereafter to expeditiously and diligently pursue remediation of the default

its obligations to enter into and maintain any necessary TA Agreements and, in the usual and ordinary course, comply with applicable Laws and to refrain from doing anything or entering into any agreement or arrangement which could reasonably be
expected to materially adversely affect its ability to perform its obligations hereunder). 
 (c) In respect of
the Buyer, the obligations referred to in Section 17.1(a) are its obligations as defined in Section 7.2(b) (in respect of its obligations to enter into and maintain any necessary TA Agreements and Pool Participant Agreements and, in the

The discontinuance of the performance by a Party of any of its obligations pursuant to Section 17.1 shall:

 (a) be in addition to any other remedy available to it; 

(b) not relieve the other Party from performance of the provisions and conditions contained in this Arrangement;

performance by the Owner pursuant to Section 17.1 shall be excluded from the Monthly Incentive Payment calculation as set out in Schedule D. 
 17.3 Termination 
 Either Party may, at its
discretion and without limitation to any other remedies it may have, immediately terminate this Arrangement upon giving the other Party written notice to that effect if:

 (a) the other Party substantially defaults in the performance of its material
obligations, other than payment obligations, under this Arrangement and does not remedy the same if reasonably remediable within 60 Days of having received written notice to do so or, if not reasonably remediable within such 60 Day period, fails to
commence within 60 Days to take steps to remedy such default and to thereafter proceed diligently and as expeditiously as reasonably possible to do so; or

any other remedy, at law or in equity, for any losses, costs, expenses, damages or other liabilities of any nature or kind

 RBuy = 0.5(CNBVu(y-1) + CNBVuy) + 0.5(MCNBVu(y-l) + MCNBVuy) + 0.5(CCNBVu(y-1) + CCNBVuy) - 0.5(CADPu(y-1) + CADPuy) + 0.5(NWCu(y-1) + NWCuy) 

where RBuy is the Mid Year Rate Base, CNBVu(y-1) and CNBVuy are the Closing Net Book Value Unit Assets in Years y-1 and y,
MCNBVu(y-1) and MCNBVuy are the Closing Net Book Value Mine Assets in Years y-1 and y, CCNBVU(y-t) and CCNBVuy are the Closing Net Book Value Corporate Service and Admin in Years y-1 and y, CADPu(y-1) and CADPuy are the Closing Accumulated
Decommissioning Provision in Years y-l and y and NWCu(y-1) and NWCuy are the Necessary Working Capital all in respect of Years y-1 and y.

 CALCULATION OF IMPUTED INCOME TAX

 C5.1 Calculation of Imputed Income Tax 

The calculation of imputed income tax includes a flow-through tax component that is the total of the corporate income tax,
and the greater of corporate surtax and large corporations tax. This flow-through component estimates the income taxes that will be due and payable by the Owner to income tax authorities. The imputed income tax also includes a deferred tax component
called the transitional tax. This deferred component is a reduction of the total imputed income tax that estimates the net present value of the tax shield that will be realised by the Owner in future

 Years. The tax shield represents the tax benefits of undepreciated capital cost pools
at the end of the PPA period. In addition, an income tax true-up component is added to the imputed income tax in order to account for any changes in forecasted indices as well as changes in income tax rates that occur during the course of a Year.

 The Imputed Income Tax for this Unit u for the Current Year y (ITuy) shall be determined as follows:

 ITuy = CITuy + max[CSTuy, LCTuy] + FTTuy + PTTuy + ITTUuy 

where CITuy is the Corporate Income Tax for this Unit u for the Current Year y as determined in Article C5.2, CSTuy is the
Corporate Surtax for this Unit u for the Current Year y as determined in Article C5.5, LCTuy is the Large Corporations Tax for this Unit u for the Current Year y as determined in Article C5.6, FTTuy is the Federal Transitional Tax for this Unit u
for the Current Year y as determined in Article C5.9, and PTTuy is the Provincial Transitional Tax for this Unit u for the Current Year y as determined in Article C5.10; 
 where the Imputed Income Tax Trueup for the Current Year y (ITTUuy) shall be determined as follows: 
 ITTUuy = ACITu(y-1) + max[ACSTu(y-1), ALCTu(y-1)] + AFTTu(y-1) + APTTu(y-1) 
 where ACITu(y.i) is the difference between the forecasted amount for Actual Corporate Income Tax for this Unit u for the Previous Year (y-1) otherwise determined in Article C5.2 and the
actual amount calculated using actual indices and actual tax rates for the Previous Year (y-1), ACSTu(y-1) is the difference between the forecasted amount for Actual Corporate Surtax for this Unit u for the Previous Year (y-1) otherwise determined
in Article C5.5 and the actual amount calculated using actual indices and actual tax rates for the Previous Year (y-1), ALCTu(y-1) is the difference between the forecasted amount for Actual Large Corporations Tax for this Unit u for the Previous
Year (y-1) otherwise determined in Article C5.6 and the actual amount calculated using actual indices and actual tax rates for the Previous Year (y-1), AFTTu(y-1) is the difference between the forecasted amount for Actual Federal Transitional Tax
for this Unit u for the Previous Year (y-1) otherwise determined in Article C5.9 and the actual amount calculated using actual indices and actual tax rates for the Previous Year (y-1), and APTTu(y-1) is the difference between the forecasted amount
for Actual Provincial Transitional Tax for this Unit u for the Previous Year (y-1) otherwise determined in Article C5.10 and the actual amount calculated using actual indices and actual tax rates for the Previous Year (y-1). 

C5.2 Calculation of Corporate Income Tax 
 The corporate income tax comprises of Federal and Provincial components. Both income tax calculations are based upon cost of equity and cost of preferred stock representing the after-tax
return earned in any Year. The net return is adjusted for permanent and timing differences between accounting and taxable income. The adjusted net return is then grossed-up to reflect the before-tax net return required. 

The Corporate Income Tax for this Unit u for the Current Year y (CITuy) shall be determined as follows: 

CITuy = FITuy + PITuy 
 FITuy= [(COEuy + COPuy + DEPNuy + IDNSCuy - Sc FCCAcuy + IFPDuy + FOTDuy) /
