ending December 31, 2031, and so forth thereafter. 
 2.3.2 Early Termination. Notwithstanding the provisions of
Section 2.3.1, early termination of this Agreement, including any Extension Term, shall only be permitted in the six (6) circumstances set out in Sections 2.3.2.1, 2.3.2.2, 2.3.2.3, 2.3.2.4, 2.3.2.5 and 2.3.2.6. 
 2.3.2.1 Early Termination for an Event of Default. In the event that an Event of Default occurs, and the Defaulting Party fails to cure such Event
of Default within the time 
  

 22 

 period(s) specified in Section 16.5.3, the Non-Defaulting Party may terminate this Agreement upon giving thirty
(30) Days’ Notice of Termination, provided that the termination date shall be the last Day of a Month. 
 2.3.2.2 Early
Termination for a Material Adverse Ruling. In the event that a Material Adverse Ruling occurs, the Party affected by such Material Adverse Ruling may, within twenty (20) Days after such Material Adverse Ruling occurs, give the other Party
Notice of Termination, in accordance with Section 2.3.3, of its intent to terminate this Agreement effective on 23:59:59 of the last Day of the Month that is twenty-four (24) Months after the Month in which the Notice of Termination is
given. Such termination date shall be referred to herein as the “Material Adverse Ruling Termination Date.” If a Party fails to give Notice of Termination within twenty (20) Days after a Material Adverse Ruling occurs, it shall have
permanently waived its right to terminate this Agreement due to such Material Adverse Ruling pursuant to this Section 2.3.2.2. Termination pursuant to this Section 2.3.2.2 shall be subject to the following procedures: 
 (a) During the ninety (90) Days immediately following the giving of the Notice of Termination, the Parties shall attempt to negotiate
amendments to this Agreement that would permit the Parties to restore the equivalent value of the economic bargain contemplated by this Agreement absent the Material Adverse Ruling. If the Parties reach agreement, such amendments will not become
effective unless, within one hundred eighty (180) Days of the date that the Notice of Termination is given, the Parties have obtained the necessary approvals of Governmental Authorities to enable the amendments to become effective without
change, condition or modification. In the event that the Parties fail (i) to reach agreement on such amendments, or (ii) to obtain the necessary approvals of Governmental Authorities, this Agreement shall terminate on the Material Adverse
Ruling Termination Date, subject to the provisions of Section 2.3.2.2(b) and 2.3.2.2.2. 
 (b) In the event that the
Parties are unable to reach agreement on the amendments provided in Section 2.3.2.2(a), either Party may, no later than ninety (90) Days after the date that the Notice of Termination is given (or, if earlier, the date that the Parties
mutually agree that they are unable to reach agreement on such amendments), give notice to the other Party of its desire to extend this Agreement for a period of up to twelve (12) Months beyond the Material Adverse Ruling Termination Date. Such
extension will be subject to the Parties (i) having first reached agreement upon the rates, terms and conditions of service for such twelve (12) Month period within one hundred twenty (120) Days of the date that the Notice of
Termination is given and executing such agreement within such one hundred twenty (120) Day period, and (ii) having received from Governmental Authorities the necessary approvals for such rates, terms and conditions without change,
condition or modification within one hundred eighty (180) Days of the date that the Notice of Termination is given. 
 (c) A “Material Adverse Ruling” is an order or action by a Governmental Authority or a change in Law that (i) either (A) modifies the rates, terms, or conditions of this Agreement, (B) disallows the recovery from
EMC of costs that are included in this Agreement, (C) for retail ratemaking or regulatory accounting and reporting purposes, 
  

 23 

 disallows costs related to this Agreement, including any disallowance of Duke’s costs related to
investments in generating facilities or binding contracts to purchase electric capacity and energy to provide service to EMC under this Agreement, or (D) for retail ratemaking or regulatory accounting and reporting purposes, assigns, allocates
or makes pro forma adjustments with respect to the revenues or costs related to this Agreement, and (ii) adversely affects the relative economic position of either Party in a material way. For purposes of this definition only, 
 (1) “material” for Duke means that the effect of the order or action by the Governmental Authority or change in Law is
reasonably projected to decrease Duke’s net revenues under this Agreement, or, in the case of a disallowance, assignment, allocation, or pro forma adjustment of revenues or costs for retail ratemaking or regulatory accounting or reporting
purposes, either (i) decrease Duke’s net costs or increase Duke’s net revenues assigned or allocated to Duke’s retail customer classes, or (ii) increase Duke’s net costs or decrease Duke’s net revenues assigned or
allocated to Duke’s wholesale customer class, by an aggregate amount equal to five percent (5%) or more of the total revenues to be paid by EMC to Duke under this Agreement over the then-remaining Term; 
 (2) “material” for EMC means that the effect of the order or action by the Governmental Authority or change in Law is reasonably
projected to increase EMC’s net costs under this Agreement by an amount equal to five percent (5%) or more of the total revenues to be paid by EMC to Duke under this Agreement over the then-remaining Term; 
 (3) an increase in a Party’s net costs is the increase in the Party’s costs as a result of the order or action by the
Governmental Authority or change in Law, less the increase (if any) in the Party’s revenues as a result of the Material Adverse Ruling; and 
 (4) a decrease in a Party’s net revenues is the decrease in the Party’s revenues as a result of the order or action by the Governmental Authority or change in Law, less the decrease (if any) in the
Party’s costs as a result of the Material Adverse Ruling. 
 (d) The foregoing amounts shall be calculated on a nominal
rather than an inflation adjusted or present value basis. Without limitation of the foregoing, EMC acknowledges that, for retail ratemaking and regulatory accounting and reporting purposes, Duke shall calculate the costs of the electric capacity and
energy used to serve EMC under this Agreement on a system average cost basis beginning January 1, 2011, or upon the commencement of the System Average Pricing Option Period, if earlier. EMC agrees that if the amount of costs that the NCUC or
the PSCSC in effect assigns or allocates to, or requires Duke to assign or allocate to, this Agreement for ratemaking or regulatory accounting and reporting purposes exceeds Duke’s system average costs, such action shall constitute a Material
Adverse Ruling if the five percent (5%) materiality standard set forth above is met. 
  

 24 

 2.3.2.2.1 A change in Duke’s net revenues or EMC’s net costs that results from a change in
this Agreement that is permitted under Section 12.3, shall not constitute a Material Adverse Ruling regardless of the impact of such change on either Party’s net costs or net revenues. 
 2.3.2.2.2 In the event that either Party believes that a Material Adverse Ruling has occurred, the Party affected by such Material Adverse Ruling shall
provide the other Party a good faith calculation together with information supporting the calculation of the projected effect of the Material Adverse Ruling and include such calculation and the cost information supporting the calculation with the
Notice of Termination. If the non-terminating Party notifies the other Party, within twenty (20) Days following the date that such Notice of Termination is given, of its good faith objection to the calculation or the cost information supporting
the calculation of the projected effect of the Material Adverse Ruling, then the Parties shall, within thirty (30) Days following the date that such Notice of Termination is given (the “Resolution Period”), attempt to resolve their
differences with respect to the calculation or the cost information supporting such calculation. If, at the conclusion of the Resolution Period, the Parties are not in agreement with respect to the calculation or cost information supporting the
calculation, then PriceWaterhouseCoopers, or such other nationally recognized accounting firm that is not then the independent auditor for either Party or any of its Affiliates or predecessors and is selected by mutual agreement of the Parties (the
“Neutral Auditors”), shall be engaged within ten (10) Days after the expiration of the Resolution Period to review the calculation and the cost information supporting the calculation and to make an independent determination as to
whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable. If the Neutral Auditors require any additional information, records, or internal analysis to make a determination as
to whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, the Party in possession of such information, records or internal analysis will provide it to the Neutral
Auditors. Each Party agrees to execute, if requested by the Neutral Auditors, a reasonable engagement letter, including customary indemnities. All fees and expenses relating to the work to be performed by the Neutral Auditors shall be borne one-half
(1/2) by the terminating Party and one-half (1/2) by the non-terminating Party. The Neutral Auditors shall act as an arbitrator to determine, based upon its independent review, whether the Material Adverse Ruling meets the materiality
standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable. The Neutral Auditors’ determination shall be made within thirty (30) Days of their selection, shall be set forth in a written statement delivered to both Parties
and shall be final, binding and conclusive. If the Neutral Auditors’ determine the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met, the Notice of Termination shall be null and void. If the
Neutral Auditors’ determine the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is met, the Notice of Termination shall be effective in accordance with its terms. The initiation of the dispute resolution
process described in this Section 2.3.2.2.2, shall not toll or otherwise delay running of the twenty-four (24) Month time period set forth in the Notice of Termination, unless the Neutral Auditors’ find that the materiality standard
set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met. The procedure set forth in this Section 2.3.2.2.2 shall be the exclusive means for the Parties to resolve any dispute as to whether a Material Adverse Ruling meets
the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2). If a Party gives a Notice of Termination based on its good faith 
  

 25 

 contention of the occurrence of a Material Adverse Ruling that meets the materiality standard set forth in
Section 2.3.2.2(c)(1) or (c)(2), as applicable, and the Neutral Auditors subsequently determine that such materiality standard has not been met, such Party shall not be in default under this Agreement solely because it gave such Notice of
Termination. 
 2.3.2.3 Early Termination for Failure of Condition Precedent. This Agreement may be terminated for failure of a
condition precedent in accordance with Section 3.5.2.2 or Section 3.5.3. 
 2.3.2.4 Early Termination Due to Implementation of
Retail Competition. Upon the date of enactment of a Law providing for implementation of retail electric service competition on a comprehensive basis in the State of North Carolina, the Parties shall enter into negotiations with the goal of
reaching agreement on amendments to this Agreement to provide for the continuation of the purchase and sale of electric capacity and energy and the provision of Scheduling Agent Services provided for in this Agreement after the commencement of such
retail electric service competition. If the Parties are not able to reach agreement by the latter to occur of (i) the date that is ninety (90) Days after the date of enactment of such Law or (ii) the date that is twenty-four
(24) Months prior to the commencement of such retail electric service competition in the State of North Carolina, then this Agreement shall terminate automatically on the date such retail electric service competition commences in the State of
North Carolina without the need for either Party to give notice. 
 2.3.2.5 Early Termination Due to Plant Calculation. In the event
that the Annual Percentage calculated in Attachment 7-9 is positive for two (2) consecutive Years, and the absolute value of such percentage is greater than ten percent (10%) then EMC may, within twenty (20) Days after the
date in such second (2nd) consecutive Year that Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4, give Duke Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month
that is twenty-four (24) Months after the Month in which the Notice of Termination is given. In the event that the Annual Percentage calculated in Attachment 7-9 is negative for two (2) consecutive Years, and the absolute value of
such percentage is greater than ten percent (10%) for any two (2) consecutive Years, then Duke may, within twenty (20) Days after the date in such second (2nd) consecutive Year that Duke provides the calculation of the Annual
Percentage pursuant to Section 7.3.2.4, give EMC Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month that is twenty-four (24) Months after the Month in which the Notice of Termination is given.
If a Party fails to give Notice of Termination within twenty (20) Days after Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4 for such second (2nd) consecutive Year, it shall have permanently waived
its right to terminate this Agreement under this Section based on the Annual Percentage for such two (2) consecutive Years; provided, that nothing in this Section 2.3.2.5 shall affect any Party’s termination rights under Sections
2.3.2.1, 2.3.2.2, 2.3.2.3, 2.3.2.4 or 2.3.2.6. 
 2.3.2.6 Early Termination Due to Extended Force Majeure. If, as a result of an event
of Force Majeure, a Party is unable to meet a material obligation hereunder for a period greater than ninety (90) Days, then the Non-Claiming Party shall have the right to terminate this Agreement upon giving a Notice of Termination within
thirty (30) Days of the expiration of 
  

 26 

 such ninety (90) Day period; provided, however, if the Claiming Party has used and continues to use all Commercially
Reasonable Efforts to remedy, cure or mitigate the event of Force Majeure, then the Non-Claiming Party’s right to give Notice of Termination shall be suspended for so long as the Claiming Party continues to use Commercially Reasonable Efforts
to remedy, cure or mitigate the event of Force Majeure. 
 2.3.3 Form of Notice of Termination. Notice of Termination made pursuant to
Sections 2.2 or 2.3 shall be given in accordance with Section 16.22 and shall state (i) the date of termination being effectuated, and (ii) the provision of this Agreement under which termination is being effectuated and the
basis for the termination. Except as otherwise provided in this Section 2.3.3, the Notice of Termination is effective when it is deemed given in accordance with Section 16.22. Once the Notice of Termination is given to a Party, it shall
not be deemed amended, modified, or otherwise revoked for any reason (other than a determination by the Neutral Auditors pursuant to Section 2.3.2.2.2 that the materiality standard is not met) unless such amendment, modification, or revocation
is mutually agreed to by both Parties in writing or unless the Parties reach agreement in accordance with Section 2.3.2.2(a). Upon receipt of the Notice of Termination, the non-terminating Party shall acknowledge receipt in writing sent in
accordance with Section 16.22 within five (5) Business Days of the receipt of the Notice of Termination. Acknowledgment of a Notice of Termination is a courtesy and shall not influence the effectiveness of the termination. Failure to
utilize a method specified in Section 16.22 shall not influence the effectiveness of the termination if the Notice of Termination is actually received by the Chief Executive Officer of the non-terminating Party within thirty (30) Days of
the date of the Notice of Termination, in which case the Notice of Termination shall be effective on the date that the Notice of Termination is actually received by the Chief Executive Officer of the non-terminating Party. 
 2.4 Absolute Nature of Termination. Both Parties hereby acknowledge, warrant, and agree that TERMINATION OF THIS AGREEMENT FOR ANY REASON PROVIDED FOR AND
PERMITTED UNDER THIS AGREEMENT IS ABSOLUTE AND FOREVER EXTINGUISHES ANY AND ALL OBLIGATIONS EXISTING UNDER THIS AGREEMENT FOR (A) DUKE TO PLAN OR PROCURE RESOURCES TO SERVE EMC, OR TO PROVIDE ANY SERVICE OR PRODUCT TO EMC, (B) EMC TO
PURCHASE FROM AND PAY DUKE FOR ANY SERVICES OR PRODUCTS, (C) EMC TO PLAN OR PROCURE RESOURCES TO SERVE DUKE, OR TO PROVIDE ANY SERVICE OR PRODUCT TO DUKE, AND (D) DUKE TO PURCHASE FROM AND PAY EMC FOR ANY SERVICES OR PRODUCTS. Upon
termination of this Agreement in accordance with Section 2.2, 2.3, 3.5.2.2, or 3.5.3, each and every obligation of Duke to provide electric energy and capacity and Scheduling Agent Services to EMC, and each and every right of EMC to purchase
electric energy and capacity and Scheduling Agent Services from Duke shall cease as a matter of contract and neither Party shall claim or assert any continuing right to continued performance, whether by “rollover,” as an
“evergreen” service, or in any other fashion based on this Agreement. By entering into this Agreement, Duke does not commit, and shall not be deemed to have committed, to plan its system to be able to provide any service to EMC beyond the
Term, and EMC agrees that it has no claim to any service beyond the Term. EMC shall not at any time oppose any filing by Duke to cancel this Agreement as a rate schedule under the Federal Power Act concurrently with, or subsequently to, the
termination of this Agreement as a contract in accordance with Section 2.2, 2.3, 3.5.2.2, or 3.5.3. The Parties acknowledge, warrant, and agree 
  

 27 

 that it is the express intention of the Parties that no action by any Governmental Authority may override the terms of
this Section 2.4 of this Agreement, and that should any Governmental Authority take any action purporting to, or that might be claimed to, override the terms of this Section 2.4, either directly or indirectly, EMC shall not make any claim
or assert any right based on or relying on such Governmental Authority action in any manner that conflicts with or frustrates the terms of Section 2.4 of this Agreement.

 Article 4  
 Sale of Electric Capacity and Energy 
 4.1 Classification of Services Provided. During the period beginning on
the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, Duke shall provide to EMC “FFR Supplemental Service”, as described in Section 4.2. Beginning
January 1, 2011, throughout the remainder of the Term of this Agreement, Duke shall provide to EMC “Partial Requirements Service”, as described in Section 4.3. 
 4.2 FFR Supplemental Service. 
 4.2.1 Character of FFR Supplemental Service. For each Hour during the period beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in
effect, Duke shall sell and deliver, and EMC shall purchase and receive, all of the electric capacity and energy that EMC requires to serve EMC’s Native Load in excess of EMC’s Base Obligation for such Hour. For example, if EMC’s
Native Load during an Hour is 800 MWs, and EMC’s Base Obligation for such Hour is 600 MWs, Duke shall supply and deliver, and EMC shall purchase and receive, 200 MWs of FFR Supplemental Service for such Hour. Duke shall supply and deliver FFR
Supplemental Service in a manner that is as firm as, and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load. Duke shall be responsible for maintaining the generation reserves needed to meet its FFR Supplemental
Service obligation. Notwithstanding anything in this Agreement to the contrary, Duke shall have no obligation to sell and deliver any electric capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.2.2 Amount of EMC’s Base Obligation. EMC’s Base Obligation for each Hour beginning on the Commencement Date, and continuing through
December 31, 2010, or any part thereof in which this Agreement is in effect, shall be as set forth in Attachment 4-1. Notwithstanding the preceding sentence, EMC’s Base Obligation shall be subject to modification (a) during Light
Load Periods in accordance with the provisions of Attachment 4-2 or (b) in accordance with the provisions of Section 5.1.4 and 5.1.5. The amounts set forth on Attachment 4-1 reflect MWs delivered at a Delivery Point.

 4.2.3 Scheduling To Meet EMC’s Base Obligation. In order to meet EMC’s Base Obligation, (a) MSCG shall be responsible for
scheduling to the Transmission Provider electric energy under the PPA to serve EMC’s Native Load and (b) Duke, acting as Scheduling Agent, shall be responsible for scheduling to the Transmission Provider, in accordance with the provisions
of Article 8, electric energy to serve EMC’s Native Load from EMC’s entitlements to the resources described in Section 5.1.3, 5.1.4 or 5.1.5. The total amount of electric energy so scheduled to the Transmission Provider in any Hour to
serve EMC’s Native Load beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall be the EMC Scheduled Amount; provided that the EMC Scheduled Amount shall
not exceed EMC’s Base Obligation for any such Hour. 
 4.2.4 Scheduling Shortfall. For each Hour beginning on the Commencement
Date, and continuing through December 31, 2010, or any portion thereof in which this Agreement is in 
  

 35 

 effect, if, for any reason, including a Force Majeure as that term is defined herein or a “force majeure”,
“uncontrollable force”, or a similar term defined in a third-party agreement, but not including Duke’s unexcused failure to comply with the provisions of Article 8, the EMC Scheduled Amount is less than EMC’s Base Obligation for
any Hour, there shall be a “Scheduling Shortfall” in the amount equal to the difference between EMC’s Base Obligation and the EMC Scheduled Amount in such Hour (“Scheduling Shortfall Amount”). For any Hour that Duke receives
information or a notice pursuant to Section 8.4.8 that there will be or has been a Scheduling Shortfall, Duke shall use Commercially Reasonable Efforts to procure and supply electric energy in a quantity sufficient to supply the Scheduling
Shortfall Amount for such Hour (“Replacement Energy”). In the event that, through the exercise of Commercially Reasonable Efforts, Duke procures Replacement Energy from a third party for resale to EMC, EMC shall pay Duke for the total cost
incurred by Duke to purchase and deliver the Replacement Energy. Duke’s curtailment of a Non-Firm Sale shall constitute a procurement of Replacement Energy from a third party and the total cost incurred by Duke shall be (i) the foregone
sales price for the Non-Firm Sale curtailed and (ii) if applicable, any charges imposed for changes to schedules for the sale of electric energy. In the event that Duke supplies Replacement Energy from its own resources, EMC shall pay Duke for
such Replacement Energy an amount equal to one hundred ten percent (110%) of Duke’s System Incremental Cost in supplying such Replacement Energy. The total charges for Replacement Energy for a Month, as determined by this
Section 4.2.4, shall constitute the Monthly Replacement Energy Charge. 
 4.2.4.1 It is expressly understood that Section 4.2.4
shall not be construed or interpreted to (i) require Duke to curtail any Firm Sales in order to supply Replacement Energy to EMC, (ii) to curtail any Non-Firm Sales except as set forth in Section 4.2.6 in order to supply such
Replacement Energy to EMC, (iii) impose upon Duke any responsibility for providing Replacement Energy for a Scheduling Shortfall that occurs after the Transmission Provider’s deadline for scheduling transmission service required for the
delivery of such Replacement Energy, or (iv) affect in any way EMC’s rights and obligations under its Network Integration Transmission Service Agreement. 
 4.2.4.2 In the event that there is or is expected to be a Scheduling Shortfall in connection with (a) EMC or its Scheduling Agent having received notice (and in the event EMC receives notice providing Duke with
evidence of such notice) of, or (b) pursuant to Section 8.4.8 Scheduling Agent having received notice of either (i) the occurrence of a “force majeure” event under the PPA, as defined in Section 4.2.4.3, or
(ii) the temporary impairment of generating resources underlying the WPSA or other resources to which EMC may have an entitlement pursuant to Section 5.1.3, 5.1.4 or 5.1.5, such that all or a portion of EMC’s entitlements to electric
energy under such agreements are or will be temporarily unavailable to EMC, then EMC may request Duke to sell electric capacity and energy to EMC for the expected duration of such Scheduling Shortfall. In the event that EMC makes such a request,
Duke shall exercise Commercially Reasonable Efforts to offer to supply electric capacity and energy to EMC under rates, terms, and conditions that Duke determines to be commercially reasonable. If the Parties reach agreement on such a sale, then
Duke shall sell and deliver and EMC shall purchase and receive the electric energy and such electric energy shall be included in EMC Scheduled Amount. 
  

 36 

 4.2.4.3 For purposes of Section 4.2.4.2, the term “force majeure” means an event or
circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in part; (ii) is not within the reasonable control of the claiming party, or the result of the negligence of the claiming
party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable manner, and, without limiting the scope of the definition, includes acts of God, or the public enemy, or insurrection,
riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court order or governmental authority or arbitration award (so long as the claiming party has
not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission service interruptions or curtailments imposed by a transmission provider in response to transmission capacity or
availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 4.2.4.3. 
 4.2.5
EMC PPA Obligation. EMC shall retain all of its rights and obligations under the PPA, including the obligation to pay all costs incurred under the PPA. 
 4.2.6 EMC Obligation to Curtail Load. During any Hour in which there is a Scheduling Shortfall, and either (i) Duke does not replace such electric energy in accordance with Section 4.2.4 or
(ii) EMC has not made, or does not have in place, arrangements to replace such electric energy, EMC shall curtail an amount of EMC’s Native Load equal to the Scheduling Shortfall Amount; provided, however, Duke shall exercise Commercially
Reasonable Efforts within the time constraints that exist to first call upon any available EMC Demand Side Management Resource Program that would not otherwise be called upon absent the Scheduling Shortfall and then if necessary curtail Non-Firm
Sales to the extent of the Scheduling Shortfall before requiring EMC to curtail EMC’s Native Load pursuant to this Section 4.2.6. Any such EMC Native Load that has been curtailed shall be restored when the Scheduling Shortfall is no longer
occurring or when the Scheduling Shortfall has been replaced either by electric energy supplied (a) by Duke in accordance with Section 4.2.4 or this Section 4.2.6 or (b) under arrangements made by EMC with third parties.

 4.3 Partial Requirements Service. 
 4.3.1 Character of Partial Requirements Service. For each Hour during the period beginning on January 1, 2011, and continuing through the termination of this Agreement, Duke shall sell and deliver, and EMC
shall purchase and receive, all of the electric capacity and energy that EMC requires to serve EMC’s Native Load in excess of the EMC Contract Resources. Duke shall be responsible for maintaining the generation reserves necessary to meet this
obligation. Duke shall supply Partial Requirements Service in a manner that is as firm as, and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load. Notwithstanding anything in this Agreement to the contrary, Duke
shall have no obligation to sell and deliver any electric capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.3.2 Scheduling of EMC Contract Resources To Serve EMC Native Load. For each Hour beginning on January 1, 2011, and continuing through the Term of this Agreement, EMC’s contractual entitlement to electric energy from the
Dispatched Combined Cycle Resources and from the Baseload Resources shall be scheduled in accordance with the provisions of Sections 4.3.3 and 4.3.4, respectively. 
  

 37 

 4.3.3 Scheduling of the Combined Cycle Resources. Duke may schedule, in accordance with Attachment
4-3 and Article 8, each of the Combined Cycle Resources pursuant to Duke’s economic dispatch as necessary to serve Duke’s total electric energy obligations. Duke shall make no adverse distinction against the Combined Cycle Resources in
determining the dispatch order of Duke’s Generation System and the Combined Cycle Resources. The Combined Cycle Resources that Duke schedules pursuant to economic dispatch shall be referred to as the “Dispatched Combined Cycle
Resources”. Except as provided in Section 4.3.3.1 and Section 4.3.3.2, EMC shall be solely responsible for all costs associated with the Combined Cycle Resources. 
 4.3.3.1 Duke shall not be obligated to pay for any costs that EMC incurs as a result of Duke’s dispatch of the Combined Cycle Resources to the
extent that Duke’s dispatch of such Combined Cycle Resources is for the purpose of serving Duke’s Native Load and, during any Year, Duke’s dispatch of a Combined Cycle Resource for that purpose does not exceed an Annual Capacity
Factor of twenty percent (20%). In the event and at such time during a Year that Duke’s dispatch of a Combined Cycle Resource to serve Duke’s Native Load exceeds an Annual Capacity Factor of twenty percent (20%), Duke shall pay EMC, in the
manner and time provided for in Article 13, the additional Energy Cost that EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource for the remainder of the Year. For example, if a Dispatched Combined Cycle Resource has a
generating capacity of one hundred (100) MWs during a Year and, as of 11:59:59 p.m. on November 30 of such Year, Duke has dispatched such resource for 175,200 MWhs for the purpose of serving Duke’s Native Load, Duke shall reimburse
EMC for the Energy Costs that EMC incurs in December of such Year as a result of Duke’s dispatch of such Dispatched Combined Cycle Resource. For the purpose of this Section 4.3.3.1, “Annual Capacity Factor” means the total amount
of electric energy generated by a Dispatched Combined Cycle Resource for the purpose of serving Duke’s Native Load during a Year divided by the product of (a) the total generating capacity of such Dispatched Combined Cycle Resource and
(b) 8,784 (during a leap year) or 8,760 (during a Year other than a leap year), multiplied by one hundred percent (100%). 
 4.3.3.2 In
the event that Duke’s dispatch of one or more of the Combined Cycle Resources is for any purpose other than to serve Duke’s Native Load, Duke shall pay EMC, in the manner and time provided for in Article 13, the additional Energy Cost that
EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource(s). 
 4.3.3.3 For purposes of Sections 4.3.3.1 and 4.3.3.2,
“Energy Cost” means, with respect to any Dispatched Combined Cycle Resource, all variable costs incurred by EMC that are associated with the production of electric energy under the WPSA, including the cost of fuel, start charges, and any
other variable charges incurred by EMC under the WPSA in connection with the electric energy dispatched by Duke from such Combined Cycle Resource regardless of NCEMC’s actual generating cost or NCEMC’s contractual source of the electric
energy. 
  

 38 

 4.3.4 Scheduling of Baseload Resources. Duke shall schedule, in accordance with Article 8,
all of the Baseload Resources to the full extent that EMC’s entitlement to such resources are available to EMC and such electric energy shall be used to serve EMC’s Native Load. EMC shall be solely responsible for all costs associated with
the Baseload Resources. The Baseload Resources that Duke schedules pursuant to this Section 4.3.4 shall be referred to as “Dispatched Baseload Resources”. 
 4.4 Excepted Load. Notwithstanding anything to the contrary herein, Duke shall have no obligation to supply electric capacity or energy required by EMC to serve Excepted Load. Excepted Load shall consist of EMC
load that is either (a) Non-Conforming Load or (b) Non-Duke Control Area Load. Non-Conforming Load shall consist of (i) EMC load resulting from the merger of EMC with another electric membership corporation or other entity (except to
the extent such load was, at the time of the merger, already being served by Duke under an agreement substantially similar to this Agreement), and (ii) EMC wholesale load. Non-Conforming Load shall also consist of discrete EMC load (a) to
which electric service from EMC shall have commenced after the Effective Date, (b) that has a projected peak demand in excess of twenty-five (25) MW for the Year in which electric service from the EMC commences, and (c) which is
projected to change within a one-minute period by a significant quantity on a recurring basis due to the nature of the retail customer’s operations (e.g., without limitation, an arc furnace). 
 4.5 Good Title. Electric energy that is delivered by Duke to EMC shall be free and clear of all liens, Claims, and encumbrances at the Delivery Points, where
title to electric energy provided by Duke hereunder shall transfer to EMC. Electric energy that is delivered by EMC to Duke shall be free and clear of all liens, Claims, and encumbrances at the point where title to the electric energy is transferred
to Duke. 
 4.6 Power Quality. All electric energy provided hereunder at the point of delivery shall be three (3) phase, sixty (60) hertz,
and at system nominal voltages.

entitlement to electric capacity or energy under such agreements and for which EMC’s consent is required (except as provided in Section 5.1.4) without first obtaining Duke’s consent to such modification. 
 5.1.3 Resource Impairment. In the event that all or a portion of the FFR Resource, or any other EMC Contract Resource, is terminated or becomes
permanently impaired, EMC shall acquire, at EMC’s expense, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent size and comparable
reliability to the EMC Contract Resource, or portion thereof, that such substitute is replacing. 
 5.1.4 New Catawba Resource. In the
event that NCEMC acquires all or part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with such entitlement being made
available throughout the Year to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the entitlement so acquired by EMC. Upon Duke’s request,
EMC shall provide evidence reasonably satisfactory to Duke demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric system generating reserves. Duke shall limit such requests to one
(1) request per Year; provided, that if Duke reasonably believes that the sufficiency or reliability of the electric system generating reserves backing EMC’s entitlement in the Catawba Nuclear Station may have changed since Duke’s
last such request, this limitation shall not apply. In the event that EMC fails to demonstrate that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase,
such reserves in an amount equal to that required under Duke’s Generation 
  

 40 

 Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as
determined under the prior sentence) supplied by Duke to EMC at the then-applicable Monthly Demand Charge. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of EMC’s Base Obligation. This Monthly
charge shall be billed by Duke in accordance with the provisions of Article 13. 
 5.1.4.1 In the event that NCEMC purchases electric
capacity and energy from Duke in lieu of NCEMC’s acquisition of all or a part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station as provided in Section 5.1.4, and NCEMC sells, allocates
or transfers a portion of such electric capacity and energy to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the electric capacity and energy
so acquired by EMC. 
 5.1.5 Non-Consent Modification of EMC’s Contract Resources. In the event that EMC’s
entitlements to electric capacity and energy are reduced in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA, the amount of the EMC’s Base Obligation shall not be affected and the provisions of Section 4.2.4.2 shall
apply, except that if the Parties are unable to reach agreement as to the rates, terms and conditions under which Duke would sell electric capacity and energy to EMC, the provisions of Section 5.1.3 shall apply. EMC shall provide written notice
to Duke as soon as reasonably practicable after EMC becomes aware of any modification to EMC’s entitlement to electric capacity and energy under the WPSA pursuant to this Section 5.1.5. In the event that EMC’s entitlements to electric
capacity and energy are increased in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA, then, prior to the effective date of such increase, EMC may elect either to (a) increase EMC’s Base Obligation by the same amount
and to the same extent as EMC’s entitlements to electric capacity and energy are increased, or (b) make arrangements for the sale of EMC’s entitlements to such electric capacity and energy to a third party or to Duke. If EMC fails to
complete the arrangements described in (b) of the preceding sentence by the effective date of the increase in entitlements, then, as of the effective date of the increase in entitlements, the EMC’s Base Obligation automatically will be
increased as described in (a) of the preceding sentence. 
 5.2 EMC Contract Resources (January 1, 2011 -
Termination of Agreement). 
 5.2.1 Identification of Contract Resources. Except as provided in Section 5.4.1, EMC’s
Contract Resources during the period January 1, 2011, through the termination of this Agreement shall consist of EMC’s entitlements to electric capacity and energy under the contracts listed in Attachment 4-3 and such additional
generation or purchased power resources or entitlements as EMC may acquire pursuant to Sections 5.2.3, 5.2.4, and 5.2.5. EMC’s entitlements under the contracts that are listed in Attachment 4-3 shall be referred to as the Partial
Requirements Resources. Partial Requirements Resources consist of two (2) categories of entitlements: Baseload Resources and Combined Cycle Resources. The amount and the material cost and operational terms and conditions of the Baseload
Resources and Combined Cycle Resources shall be as set forth in Attachment 4-3, subject to modification in accordance with Sections 5.2.3 and 5.2.4. Except as provided in this Section 5.2.1, EMC shall not, without first obtaining

  

 41 

 Duke’s prior written consent, enter into any other contracts for, or acquire any ownership interest in or
contractual entitlement to, any additional electric generating resources or electric capacity or energy under which electric capacity and energy would be used to serve EMC’s Native Load during the Term. 
 5.2.1.1 Extension of WPSA. Consistent with the provisions of Section 5.2.2, EMC shall have the right, without the prior consent of Duke, to
extend the term of the WPSA under substantially the same terms and conditions as exist at the time that EMC seeks to extend the term of the WPSA. If EMC extends the term of the WPSA in accordance with this Section 5.2.1.1, the EMC Contract
Resources listed in Attachment 4-3 shall be deemed to be changed accordingly. 
 5.2.2 Changes To Partial Requirements
Resources. Commencing January 1, 2011, through the termination of this Agreement, EMC shall not (a) take any action that would materially affect the quantity or quality of EMC’s entitlement to electric capacity and energy from the
Partial Requirements Resources without first obtaining Duke’s prior written consent, or (b) agree to any modification to provisions of the WPSA that would increase or decrease EMC’s entitlement to electric capacity or energy under
such agreement and for which EMC’s consent is required (except as provided in Section 5.2.4) without first obtaining Duke’s consent to such modification. 
 5.2.2.1 Modifications Effective After Termination. Notwithstanding the provisions of Section 5.2.2, EMC shall be permitted to agree to any resource modification under the WPSA without obtaining Duke’s
consent to the extent that such resource modification will become effective after the Term; provided, that if such resource modification will become effective prior to the end of the Term, EMC’s Partial Requirements Resources and Duke’s
obligation to provide Partial Requirements Service shall not be modified prior to the date that this Agreement is terminated unless Duke consents to such modification. 
 5.2.2.2 Sufficiency of Reserves. Upon Duke’s request, EMC shall provide evidence reasonably satisfactory to Duke demonstrating that each of EMC’s Partial Requirements Resources is backed by sufficient
and reliable electric system generating reserves. Duke shall limit such requests to one (1) request per Year with respect to any Partial Requirements Resource; provided, that if Duke reasonably believes that the sufficiency or reliability of
the electric system reserves backing any Partial Requirements Resource may have changed since Duke’s last such request, this limitation shall not apply with respect to that Partial Requirements Resource. In the event that EMC fails to
demonstrate that its entitlement in a Partial Requirements Resource is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s Generation
Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined under the prior sentence) supplied by Duke to EMC and the then applicable Monthly Demand Charge. This Monthly charge
shall be billed by Duke in accordance with the provisions of Article 13. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of the amount of Partial Requirements Resources, Baseload Resources or
Combined Cycle Resources. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of a material change to the seller’s service obligations under the contracts listed in Attachment 4-3; provided,
that such notice shall be for information purposes only, and shall not affect any other obligations of either Party under this Agreement. 
  

 42 

 5.2.3 Non-Consent Partial Requirements Resource Modifications. In the event that EMC’s
entitlements are modified pursuant to Section 2.9(b) or Section 2.9(c) of the WPSA, EMC’s Partial Requirements Resources shall be modified in the same amount and to the same extent. To the extent that a Partial Requirements Resource
is modified pursuant to this Section 5.2.3, and the modification changes EMC’s entitlement in a resource listed as a Baseload Resource in Attachment 4-3, the amount of such Baseload Resource, as listed in Attachment 4-3,
shall be deemed to be changed accordingly. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of any modification to EMC’s entitlement to electric capacity and energy under the WPSA pursuant to
this Section 5.2.3. To the extent that a Partial Requirements Resource is modified pursuant to this Section 5.2.3, and the modification changes EMC’s entitlement in a resource listed as a Combined Cycle Resource in Attachment
4-3, the amount of such Combined Cycle Resource, as listed in Attachment 4-3, shall be deemed to be changed accordingly. 
 5.2.4
New Catawba Resource. In the event that NCEMC acquires all or part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with
such entitlement being made available throughout the Year to EMC (through modification of the WPSA or pursuant to a new contract), the entitlement or resource so acquired by EMC shall constitute an additional Partial Requirements Resource, and shall
be deemed to be an additional Baseload Resource. Upon Duke’s request, EMC shall provide evidence reasonably satisfactory to Duke demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric
system generating reserves. Duke shall limit such requests to one (1) request per year; provided, that if Duke reasonably believes that the sufficiency or reliability of the electric system generating reserves backing EMC’s entitlement in
the Catawba Nuclear Station may have changed since Duke’s last such request, this limitation shall not apply. In the event that EMC fails to demonstrate that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable
generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s Generation Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of
reserves (as determined under the prior sentence) supplied by Duke to EMC and the then-applicable Monthly Demand Charge. This Monthly charge shall be billed by Duke in accordance with the provisions of Article 13. Duke’s provision and
EMC’s purchase of such reserves shall not affect the determination of the amount of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. 
 5.2.4.1 In the event that NCEMC purchases electric capacity and energy from Duke in lieu of NCEMC’s acquisition of all or a part of Saluda River Electric Cooperative’s existing ownership interest in the
Catawba Nuclear Station as provided in Section 5.2.4, and NCEMC sells, allocates or transfers a portion of such capacity and energy to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Baseload Resources shall
be increased by an amount equal to the amount of the electric capacity and energy so acquired by EMC. 
  

 43 

 5.2.5 Resource Impairment. In the event that all or a portion of an EMC Contract Resource is
terminated or becomes permanently impaired, EMC shall acquire, at EMC’s cost, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent
size and comparable reliability to the EMC Contract Resource, or portion thereof, that such substitute resource is replacing, and that Duke reasonably agrees is sufficiently reliable. EMC’s acquisition of such substitute resource shall not
affect the determination of the amount of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. 
 5.3 No Duke Obligation for
Customer Resources. Unless otherwise explicitly provided in this Agreement, nothing herein shall be interpreted or construed as imposing upon Duke any obligations or liabilities, or for transferring to Duke any EMC obligations or liabilities,
under or otherwise pertaining to any EMC Contract Resource, nor shall anything in this Agreement be interpreted or construed as creating or implying any contractual or other relationship between Duke and any other party as to a EMC Contract
Resource. 
 5.4 New Customer Resources. Except as provided in Section 5.4.1, Duke shall have no obligation to amend this Agreement and EMC shall
not make an application to FERC requesting that FERC require that any amendment be made to this Agreement, to accommodate any contractual entitlement to and/or ownership interest in or pertaining to any new electric capacity and/or energy resource
that EMC may obtain after the Effective Date. 
 5.4.1 PURPA Resources. Nothing herein shall limit EMC’s right to purchase
electric capacity and energy from a Qualifying Facility or other renewable resources pursuant to PURPA (“PURPA Resource”). If, during the Term, EMC purchases electric capacity and energy from a PURPA Resource with a nameplate capacity
equal to or greater than one (1) MW, then, for each Month during the period of such purchase: (i) the average hourly integrated electric energy delivered to EMC by such PURPA Resource during the Hours used for determination of the EMC
Monthly Demand Quantity determined in accordance with Section 7.1.4.1 or 7.2.4.1 as applicable or used for determination of the Monthly Billing Demand determined in accordance with Section 7.2.6.3.2 or Section 7.3.2.2 increased for
losses between the point of measurement of EMC’s Native Load and the Duke generation level, shall be added to the EMC Monthly Demand Quantity determined in accordance with Section 7.1.4.1 or 7.2.4.1 as applicable or to the Monthly Billing
Demand determined in accordance with Section 7.2.6.3.2 or Section 7.3.2.2 for such Month, as applicable; (ii) for purposes of calculating the electric energy charges under Sections 7.1.5, 7.2.5, 7.2.6.4 and 7.3.3, as applicable, the
amount of electric energy provided to EMC by such PURPA Resource during an Hour, increased for losses between the point of measurement of EMC’s Native Load and the Duke generation level, shall be added to EMC’s Native Load and to the EMC
Group Native Load for such Hour; and (iii) Duke shall credit EMC, on a Monthly basis, an amount equal to the electric capacity and energy credits to which EMC would be entitled as set forth in Duke’s retail electric tariff on file with the
NCUC, Schedule PP-H or Schedule PP-N (as applicable), Interconnected to Distribution System or Transmission System (as applicable), or its successor tariff, if the capacity and electric energy provided to EMC by such PURPA Resource were provided to
Duke pursuant to and in accordance with such schedules. The interconnection to Duke’s (rather than the EMC’s) Distribution System or Transmission System, as those terms are defined in the schedules, will determine whether the Distribution
System or Transmission System rates apply. EMC will coordinate with Duke to 
  

 44 

 determine the proper application of these schedules. If Schedule PP-H or Schedule PP-N do not apply to the PURPA
Resource, then Duke shall credit EMC, on a Monthly basis, an amount equal to the electric capacity and energy credits to which EMC would be entitled under PURPA if the electric capacity and electric energy provided to EMC by such PURPA Resource were
provided to Duke pursuant to PURPA. EMC’s purchase of the electric capacity and energy from a PURPA Resource shall not affect the determination of the Annual Capacity Quantity determined in accordance with Sections 3.5.2.3.1, 3.5.2.3.2 or
3.5.2.3.3, as applicable. 
 Article 6  
 Priority of Service 
 6.1 Interruption of FFR Supplemental Service and Partial Requirements Service. FFR
Supplemental Service and Partial Requirements Service shall have an interruption priority equivalent to Duke’s Native Load. It is expressly understood and agreed that, except for Duke’s failure to comply with Section 6.2 or as
provided in Section 6.4, Duke shall not be liable to EMC for damages resulting from any such interruptions or impairment of FFR Supplemental Service or Partial Requirements Service. Duke shall use Commercially Reasonable Efforts to notify EMC
by telephone of any scheduled interruption or scheduled impairment of service hereunder and shall use Commercially Reasonable Efforts to confirm such notice by facsimile, electronic mail, or letter on the same date such notice was given. Duke shall
notify EMC by telephone of any unscheduled interruption or impairment of service hereunder as soon as reasonably practicable under the circumstances resulting in such unscheduled interruption or impairment of service. Duke shall use Commercially
Reasonable Efforts to remove all causes of such interrupted or impaired service hereunder. 
 6.2 Curtailments of Load. Except as provided in
Section 4.2.6, EMC’s Native Load shall be subject to curtailment only in accordance with this Section 6.2. In the event that Duke curtails Duke Native Load for any reason, including Force Majeure, EMC shall curtail its load as
directed by Duke. Except as provided in Section 4.2.6, Duke shall not adversely distinguish against EMC’s Native Load in curtailing Duke’s Native Load and directing EMC to curtail EMC’s Native Load; provided, however, that Duke
has sole responsibility to design all curtailments, and may order any manner of curtailment that Duke believes is appropriate so long as EMC’s Native Load and Duke’s Native Load present in the electrical area being curtailed are curtailed
on a non-discriminatory basis. In permitting EMC to restore EMC’s Native Load and restoring Duke’s Native Load that was curtailed, Duke shall not adversely distinguish against EMC’s Native Load, except as provided in
Section 4.2.6. The load curtailment and restoration provisions set forth in this Section 6.2 are in addition to, and without limitation of, the load curtailment and restoration provisions set forth in Section 4.2.6. 
 6.3 Emergency Load Curtailment Program. EMC agrees to implement an emergency load curtailment program for the curtailment of EMC’s Native Load in the event a
load curtailment order is made by Duke. EMC shall comply with its obligation to implement and maintain an emergency load curtailment program and to curtail EMC’s Native Load in the manner specified by Section 6.2. 
  

 45 

 6.4 Substitute Energy. In the event that Duke fails to deliver a sufficient quantity of electric energy to meet
its obligations to provide FFR Supplemental Service or Partial Requirements Service, as the case may be, and Duke’s failure to deliver such electric energy is not pursuant to a curtailment permitted under Section 4.2.6 or 6.2 of this
Agreement, or is otherwise excused under this Agreement, Duke shall pay to EMC an amount equal to EMC’s Cover Costs, if any, incurred for the electric energy that EMC obtained to replace such electric energy (“Substitute Energy”) Duke
failed to supply. EMC’s Cover Costs shall be equal to Substitute Energy Costs incurred by EMC for the Substitute Energy minus the costs that EMC would have incurred had Duke supplied the electric energy to EMC. EMC shall bill its Cover Costs to
Duke in accordance with the provisions of Article 13. In the event that EMC incurs Cover Costs for Substitute Energy over a period that extends past the Month in which Duke’s failure to deliver electric energy occurs, then Duke shall pay
the Cover Costs incurred in the following Month(s) in accordance with the billing and payment provisions of Article 13. 
 6.5 Substitute Energy
Costs. Substitute Energy Costs shall be equal to (i) in the case in which EMC contracts with an energy supplier to provide Substitute Energy to EMC, the cost that EMC, acting in a commercially reasonable manner, incurs to purchase such
Substitute Energy, or (ii) in the case in which Substitute Energy is provided to EMC by the Control Area operator, system operator, or similar entity providing such service on behalf of load (or load serving entities), the cost to EMC imposed
on EMC by such Control Area operator, system operator, or other entity providing such Substitute Energy. In either case, Substitute Energy Costs shall include ancillary services charges, if any, reasonably incurred by EMC to the point where electric
energy is delivered to the Transmission System or imposed to the point where electric energy is delivered to the Transmission System by the Control Area operator, system operator, or other entity providing Substitute Energy, including congestion
charges, energy imbalance charges, backup capacity charges, replacement capacity charges, deficient capacity charges, commitment fees, ratcheted demand and similar charges incurred by EMC in obtaining such Substitute Energy.

of Replacement Energy provided to EMC (the “Reserve Capacity Amount”). This charge shall commence on the Day following the Day on which Duke provided Replacement Energy to EMC, and shall terminate on December 31 of that Year. For
example, if Duke provides a maximum amount of 100,000 kWh of Replacement Energy to EMC in any given Hour on July 15, 2007, and the reserves that would be required for a 100,000 kW generating resource under Duke’s Generation Planning
Practices is 17,000 kW, EMC shall be responsible for a Monthly Reserve Capacity Charge for 17,000 kW from July 16, 2007, through December 31, 2007, subject to increase as provided in the next sentence. In the event that Duke provides
Replacement Energy to EMC for any additional Hours during such Year, and the amount of Replacement Energy provided during any such Hours is greater than 
  

 57 

 that previously provided during the Year, then the Reserve Capacity Amount shall be increased to reflect such greater
amount of Replacement Energy, effective the Day after the Replacement Energy is provided. In the event that Duke provides Replacement Energy to EMC in a subsequent Year, the foregoing provisions shall apply, and EMC shall pay Monthly Reserve
Capacity Charges with respect to such Replacement Energy as provided above. Notwithstanding anything in this Section 7.4 to the contrary, the Monthly Reserve Capacity Charges shall terminate no later than December 31, 2010. Any Monthly
Reserve Capacity Charge, or increase in such charge, that begins on a Day other than the first Day of the Month shall be adjusted pro rata for that Month to reflect the number of Days during the Month in which the charge or charge increase was in
effect. 
 7.4.1 Force Majeure Events. Notwithstanding the provisions of Section 7.4, in the event that Duke provides Replacement
Energy to EMC due to the occurrence of a force majeure event, EMC shall not incur a Monthly Reserve Capacity Charge due to Duke’s provision of Replacement Energy for the first twenty-four (24) Hours following such occurrence. For purposes
of this Section 7.4.1, the term “force majeure” means an event or circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in part; (ii) is not within the reasonable
control of the claiming party, or the result of the negligence of the claiming party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable manner, and, without limiting the scope of
the definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court order or
governmental authority or arbitration award (so long as the claiming party has not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission service interruptions or curtailments
imposed by a transmission provider in response to transmission capacity or availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 7.4.1. 
 7.5 Payment. All charges or payments contemplated by this Article 7 shall be made in accordance with provisions of Article 13. 
 7.6 Determination of EMC Capacity and Energy Demands. For purposes of determining the electric capacity and energy charges under this Agreement, EMC’s Native
Load demands shall be as determined under the NOA (which demands shall include the adjustments under the NOA for losses between the point of delivery under the NITSA and the point of measurement, and the corrections under the NOA for any metering
failures or inaccuracies), and shall be increased by (1 / (1 - TLF ), in order to reflect such demands at the generation level (i.e., at the point at which power is available for transmission). Metered receipts used in billings and accounting
hereunder will in all cases include adjustments for such losses. TLF shall be equal to the transmission loss factor set forth in the Transmission Provider’s OATT, and shall be expressed as a decimal. For example, if the transmission loss factor
in the Transmission Provider’s OATT is three percent (3%), then ( 1 / (1 - TLF )) shall be equal to ( 1 / (1 -.03)), or ( 1 / .97 ). In the event that the NOA is terminated, or the electric capacity and energy demands measured under the NOA no
longer include an adjustment for losses between the point of delivery under the NITSA and the point of measurement or provisions for correcting such demands for metering failures or inaccuracies, then, for purposes of determining the capacity and
energy charges under this Agreement, EMC’s metered electric capacity and energy demands shall be adjusted for losses 
  

 58 

 between the point of delivery under the NITSA and point of measurement and further increased by ( 1 / (1-TLF)), in
order to reflect such demands at the generation level (i.e., at the point at which power is available for transmission), and suitable arrangements shall be made by the Parties for correcting such demands due to metering failures or
inaccuracies.

 Article 9 
 Transmission and Ancillary Services 
 9.1 Delivery
Obligations. Duke shall be responsible for making all arrangements necessary and paying for all costs incurred under contractual arrangements necessary to deliver the electric energy provided hereunder to the Delivery Points. EMC shall be
responsible for making and paying for all contractual arrangements necessary for the delivery of the electric energy provided hereunder from the Delivery Points. 
 9.2 Transmission Arrangements. This Agreement does not obligate Duke to provide any Transmission Service or Ancillary Services, and does not confer upon EMC any rights to service over the Transmission System. EMC shall be responsible
for making separate contractual arrangements with the Transmission Provider for all Transmission Service and Ancillary Services to be provided to EMC. 
 9.3
Ancillary Services. Duke shall make Commercially Reasonable Efforts to assist in any effort by EMC to have the Transmission Provider recognize that the electric capacity and energy provided hereunder satisfies one or more of such Transmission
Provider’s Ancillary Services requirements; provided, however, that nothing in this Section 9.3 shall in any way obligate Duke to provide, make arrangements for, or pay for any Ancillary Services except as expressly provided for in
Section 9.3.1. 
 9.3.1 Energy Imbalance Responsibility. Duke shall reimburse EMC in accordance with the provisions of Article 13
for any Hour in which, as a result of Duke’s unexcused failure to 
  

 62 

 comply with the provisions of Article 8, Energy Imbalance Service charges are incurred by EMC in accordance with the
Transmission Provider’s OATT. EMC shall reimburse Duke in accordance with the provisions of Article 13 for any Hour in which, as a result of Duke’s unexcused failure to comply with the provisions of Article 8, Energy Imbalance Service
compensation is provided to EMC in accordance with the Transmission Provider’s OATT. 
 9.4 Regional Transmission Organization. If an ISO, RTO,
ITC or other future organization, agency or authority that has been approved by FERC to serve as the Transmission Provider, then Duke and EMC will reasonably cooperate to make or enter into arrangements with such entity to assist such entity with
the implementation of this Agreement. It is expressly understood that neither the implementation of an ISO, RTO, ITC or other future organization, agency or authority that has been approved by FERC to serve as the Transmission Provider nor the
failure of the Parties to enter into the arrangements contemplated under this Section 9.4 shall relieve either Party of any obligations under this Agreement. 
 9.4.1 Cost Responsibility. Except as provided in Section 9.3.1, it is expressly understood that nothing herein shall be construed to in any way relieve EMC of, or impose upon Duke, the responsibility for
any fees, costs, or charges (including but not limited to congestion costs, transmission losses, or the costs or charges to secure financial transmission rights or the equivalent thereof) that may be imposed on EMC by an ISO, RTO, ITC or other
future organization, agency or authority that has been approved by FERC to serve as the Transmission Provider in connection with the provision of Transmission Service or Ancillary Services. It is further expressly understood that Duke shall have no
right or interest in any financial transmission rights or the equivalent thereof that are allocated, assigned, transferred or acquired by EMC. 
 9.4.2 Congestion Costs. In the event that the Transmission Provider implements a pricing methodology that allocates congestion costs on a locational basis, in determining the dispatch order of Duke’s Generation System, Duke
shall make no adverse distinction between Duke’s Native Load and Duke’s obligations to supply FFR Supplemental Service or Partial Requirements Service, as applicable under this Agreement. Duke further agrees that, in the event it
designates Delivery Points for Duke’s Generation System, Duke shall make no adverse distinction between Duke’s Native Load and Duke’s obligations to supply FFR Supplemental Service or Partial Requirements Service, as applicable under
this Agreement. The Parties shall reasonably cooperate with each other in an effort to develop and implement congestion management strategies designed to minimize the incurrence of congestions costs associated with the delivery of electric energy
under this Agreement. Duke will provide EMC with recommended strategies to manage such congestion costs, under terms that would not subject Duke’s Native Load to any costs that Duke would not otherwise incur, and if EMC agrees with such
recommendation, Duke will use Commercially Reasonable Efforts to implement the recommended congestion management strategies. Duke shall also use Commercially Reasonable Efforts to comply with the congestion management rules that may be adopted by
the Transmission Provider. 
  

 63 

 Article 10 
 Operating Committee 
 10.1 Operating Committee. The Parties shall establish an Operating Committee consisting
of one (1) Representative each. The Operating Committee shall act only by unanimous agreement or consent. Duke and EMC shall designate their respective Representatives to the Operating Committee, plus any alternate, by written notice delivered
in accordance with Section 16.22 within thirty (30) Days after the Effective Date. Each Party’s Representative on the Operating Committee is authorized to act on behalf of such Party with respect to any matter arising under this
Agreement. 
 10.2 Duties of the Operating Committee. The Operating Committee shall facilitate the coordination and interaction between the Parties
with respect to the performance of the duties and obligations imposed on the Parties hereunder, including development or revision of appropriate protocols and procedures therefor. The Operating Committee shall not, however, have any authority to
modify or otherwise alter the Parties’ rights and obligations under this Agreement. 
 Article 11 
 Demand Side Management 
 11.1 Availability of
Demand Side Management Resource Programs. EMC may make available to EMC’s Native Load customers EMC Demand Side Management Resource Programs to the same extent and under comparable terms and conditions as Duke’s Demand Side Management
Resource Programs; provided, however, that EMC may not make available to EMC’s Native Load customers any demand side management resource programs or similar programs other than such EMC Demand Side Management Resource Programs unless EMC is
otherwise required by RUS or by applicable Law to make other demand management side resource programs available to EMC’s Native Load customers or is otherwise permitted under Section 11.7. Except as set forth in Section 4.2.6, the
terms and conditions of EMC Demand Side Management Resource Programs shall be applied to EMC’s Native Load customers and enforced by Duke in the same or comparable manner as they are applied to Duke’s Native Load retail customers and
enforced by Duke. Except as set forth in Section 4.2.6, in implementing and operating such EMC Demand Side Management Resource Programs, Duke shall make no adverse distinction with respect to EMC’s Native Load. 
 11.2 Changes to Demand Side Management Resource Programs. Upon ninety (90) Days prior written notice, Duke shall advise EMC of any modifications, additions,
or deletions that have been or will be made to the Demand Side Management Resource Programs, and the EMC Demand Side Management Resource Programs available hereunder to EMC’s Native Load customers shall be deemed to have been revised to reflect
such modifications, additions, or deletions without any further action required by either Party. 
 11.3 Credits. Except for any EMC Demand Side
Management Resource Program implemented pursuant to Section 11.7 of this Agreement, for each EMC Native Load customer 
  

 64 

 that implements an EMC Demand Side Management Resource Program, EMC shall be entitled to a billing credit. Such billing
credit shall be calculated in accordance with the credit applicable for the Demand Side Management Resource Program, as specified in the rider approved and on file with NCUC for such Demand Side Management Resource Program. Each Month, Duke shall
aggregate the total billing credits to which EMC is entitled pursuant to this Section 11.3, and provide EMC a credit on the Monthly statement delivered in accordance with Section 13.2 equal to the total billing credits for such Month.

 11.4 Necessary Arrangements. To the extent that an EMC Native Load customer agrees to implement an EMC Demand Side Management Resource Program, the
Parties shall cooperate in preparing any detailed implementation procedures and arrangements required to implement such program, provided that, except for any EMC Demand Side Management Resource Program implemented pursuant to Section 11.7 of
this Agreement, Duke shall retain sole operational control over such EMC Demand Side Management Resource Program implemented. The failure of the Parties to agree on detailed implementation procedures and obligations shall not affect Duke’s
obligation to provide EMC with credits as determined by Section 11.3. 
 11.4.1 Audits. For each EMC Demand Side Management
Resource Program whose credit depends upon the number of EMC Native Load customers, EMC shall be required to provide Duke written notice, by no later than January 31 of each Year, of the number of EMC Native Load customers with whom EMC has
entered into arrangements pursuant to this Section 11.4 for such EMC Demand Side Management Resource Program. Duke shall have the right periodically to perform audits, in accordance with the terms of Section 13.6, to verify the accuracy of
the notices concerning the number of EMC Native Load customers with whom EMC has entered into arrangements for each EMC Demand Side Management Resource Program. Based on the results of such audits, Duke shall be entitled, in accordance with the
terms of Section 13.2.2, to revise or adjust the level of credits that Duke previously had provided EMC. 
 11.5 Start-Up Conditions. No later
than sixty (60) Days after the Effective Date, Duke shall conduct a system-wide test of each EMC Demand Side Management Resource Program to determine its capability. Duke shall provide EMC with the results of such test no later than five
(5) Business Days after the completion of the system-wide test. Duke shall not be required to provide credits for EMC Demand Side Management Resource Programs unless the applicable standards and requirements specified for Duke’s Demand
Side Resource Management Programs under the riders approved and on file with the NCUC shall have been met, and the testing provided for in this Section 11.5 shall have been accomplished. 
 11.6 Periodic Testing. Duke shall have the right periodically, but no less than once per Year, to conduct a system-wide test of each EMC Demand Side Management
Resource Program to determine whether the tested EMC Demand Side Management Resource Program is capable of providing a level of demand reduction equal to the level of the credit that EMC is, at the time of such system-wide test, receiving for such
EMC Demand Side Management Resource Program. Subject to Section 11.6.1, if, at the time of such system-wide test, one or more EMC Demand Side Management Resource Program(s) do not provide the level of demand reduction equal to the level of the
credit that EMC is receiving for such EMC Demand Side Management Resource Program(s), Duke shall have the right to (i) reduce the credit provided to EMC to the actual level of demand reduction provided at the time of the system-wide test and,
in accordance with the 
  

 65 

 terms of Section 13.2.2, to revise or adjust the level of credits that Duke previously had provided EMC, and
(ii) provide written notice within ninety (90) Days of the system-wide test, to cancel such EMC Demand Side Management Resource Program(s). 
 11.6.1 Retesting. Within sixty (60) Days of any failure of a system-wide test for an EMC Demand Side Management Resource Program, EMC shall have the right to have Duke conduct a retest in order to
demonstrate that such EMC Demand Side Management Resource Program is capable of providing the level of demand reduction equal to the level of the credit that EMC previously was receiving for such EMC Demand Side Management Resource Program. To the
extent that any such system-wide retest demonstrates that the EMC Demand Side Management Resource Program is capable of providing demand reduction, the credit provided to EMC shall be restored to the prior level or such lesser level as demonstrated
by the result of such rescheduled test and, to the extent applicable, Duke shall, in accordance with the terms of Section 13.2.2, revise or adjust the level of credits that Duke previously had provided EMC and any notice to terminate rendered
by Duke pursuant to 11.6 shall be null and void. 
 11.7 EMC Demand Side Management. If Duke’s Annual Planning Period shifts from the Summer
Period to the Winter Period, then EMC shall have the authority to implement and call upon EMC Demand Side Management Resource Programs to control EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated
sixty-minute) Duke Schedule 1 Demands during the Winter Period to the level equal to but not below the average of (i) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute)
Duke Schedule 1 Demands during the immediately preceding Summer Period and (ii) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the
second preceding Summer Period. For example, if (i) the Annual Planning Period during May 2012 - April 2013 is the Summer Period (May 2012 - September 2012), and the average of EMC’s integrated sixty (60) minute EMC Native Load
demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during such period is 100 MWs; and (ii) the Annual Planning Period during May 2013 - April 2014 is the Winter Period (October 2013 - April 2014), and the
average of EMC’s integrated sixty (60) minute EMC Native Load demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during the Summer Period immediately preceding such Winter Period (i.e., May 2013 - September
2013) is 102 MWs; then EMC may call upon EMC Demand Side Management Resource Programs to control EMC’s integrated sixty (60) minute EMC Native Loads demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands
during October 2013 - April 2014 to the level equal to but not below 101 MWs. It is expressly acknowledged that (a) Duke shall also have the right to call upon any available EMC Demand Side Management Resource Program implemented pursuant to
this Section 11.7, and (b) EMC shall not be entitled to a billing credit under Section 11.3 (or any other provision of this Agreement) in connection with any EMC Demand Side Management Resource Program implemented pursuant to this
Section 11.7. 
  

 66 

 Article 12 
 Modification of This Agreement 
 12.1 Unilateral Modification. Except as provided in Section 12.3:

 No unilateral modification, amendment or other change to the terms of this Agreement shall be permitted or deemed effective for any reason,
and the rates, terms and conditions specified herein shall not be subject to change through application to FERC pursuant to the provisions of Sections 205 or 206 of the Federal Power Act absent the written agreement of both Parties. Any
amendment or modification to this Agreement shall be deemed enforceable if and only if such amendment or modification (a) has been reduced to writing, (b) has been agreed to and duly executed by both Parties in writing, and (c) has
received all requisite approvals of Governmental Authorities necessary for the effectiveness thereof. Each Party hereby irrevocably waives its rights, including any rights under Sections 205 and/or 206 of the Federal Power Act, to file a
complaint, request an investigation, or make any unilateral rate-change request seeking: (a) an order from FERC finding that any rate or provision in this Agreement is unjust or unreasonable; (b) any refund with respect to this
Agreement’s rates; or (c) any other unilateral modification to this Agreement. Each Party agrees not to make any such unilateral filing or request, and agrees and warrants that these covenants and waivers shall be binding notwithstanding
any regulatory, market, or other change that may occur at any time during the Term. 
 12.2 Mobile-Sierra Public Interest Standard. Except as
provided in Section 12.3, to the extent this Agreement is challenged by any person or its terms are subjected to review under the Federal Power Act or other Laws, the “just and reasonable” standard shall not apply. Instead, absent the
agreement of both Parties to the proposed change, and except as provided in Section 12.3, the standard of review for changes to this Agreement proposed by a Party, a non-party, or FERC acting sua sponte shall be the “public
interest” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956); Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956). 
 12.3 Changes To Certain Charge Components. Notwithstanding anything else herein to the contrary, nothing contained herein shall be construed as affecting in any
way the right of either Party to unilaterally make application to FERC under Sections 205 or 206 of the Federal Power Act (i) to change the depreciation rates and nuclear decommissioning accrual used in Schedule 1, (ii) to
include additional cost items that are incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable, to EMC that are not included in Schedule 1, (iii) to exclude from Schedule 1 cost items
that are no longer incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable to EMC, or (iv) to change Schedule 1 to reflect changes in Duke’s accounting consistent with the Accounting
Requirements (including the addition of new accounts and the removal of obsolete accounts). In addition, in the event that (a) EMC implements new time-of-use rates or materially modifies its existing time-of-use rates, for some or all of
EMC’s Native Load customers, (b) such rates result in a reduction of EMC’s Monthly Billing Demand under Sections 7.2.6.3.2 or 7.3.2.2, and (c) such Monthly Billing Demand reduction does not result in a commensurate reduction
in the EMC demands that Duke utilizes in Duke’s Generation Planning Practices, Duke may make unilateral application to 
  

 67 

 FERC under Section 205 of the Federal Power Act to change the calculation of the Monthly Billing Demand set forth in
Sections 7.2.6.3.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. In the event that Duke makes such a filing with FERC, EMC may oppose such filing, and, in addition, shall be free
to propose any other method for calculating the Monthly Billing Demands set forth in Sections 7.2.6.3.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. 
 12.4 Standard of Review for Permitted Changes. The Parties acknowledge that, as of the Effective Date, FERC has issued a proposed rule that, if adopted, would
specify the language for parties to include in future agreements where the parties intend that the “just and reasonable” standard of review apply to amendments to the agreements. Notwithstanding the language that ultimately may be adopted
by FERC, it is the intent of the Parties that the standard of review that FERC shall apply when acting on proposed modifications to this Agreement that are permitted under Section 12.3, either on FERC’s own motion or on behalf of a
signatory or non-signatory, shall be the “just and reasonable” standard of review rather than the “public interest” standard of review. 
 12.5 Scope of Waiver. Nothing in this Article 12 shall be construed to modify or limit any Party’s right to enforce the express terms of this Agreement as they are written in this Agreement. 
 Article 13 
 Billing and
Payment 
 13.1 Billing Period. Unless otherwise specifically agreed upon by the Parties in the terms of this Agreement or otherwise in writing,
the Month shall be the standard period for determining all billings and payments under this Agreement. 
 13.2 Billing Statements. 
 13.2.1 Initial Statements. After the end of each Billing Period, Duke shall deliver to EMC a statement setting forth for the Billing Period
(i) the sum of the electric energy delivered and/or received for all Hours during that Billing Period, and (ii) Duke’s calculation of any amounts due from EMC under this Agreement for the Billing Period. In addition, in the event that
there are amounts due from Duke to EMC under this Agreement for a Billing Period, EMC shall deliver to Duke, after the end of such Billing Period, a statement setting forth for the Billing Period EMC’s calculation of any amounts due from Duke
under this Agreement for the Billing Period. Notwithstanding the foregoing, a Party’s failure to render a statement as set forth above shall not relieve the other Party from its obligation to make payment to the billing Party when such
statement is rendered, provided such statement is rendered within one (1) year after the end of the Billing Period. 
 13.2.2
Subsequent Payment Adjustments. The Parties understand that in certain cases Monthly billings will need to be made on an estimated basis. In addition, the Parties understand that after-the-fact adjustments to amounts owed or revenues received
may be made in order to 
  

 68 

 reflect correctly the amounts payable by one Party to the other under this Agreement. Each Party shall cooperate in good
faith with the other Party to obtain the requisite information and perform the necessary computations so as to true-up or otherwise adjust any estimated or adjusted billings promptly. 
 13.3 Timeliness of Payment. Unless otherwise agreed by the Parties, all statements rendered under this Agreement, whether by Duke or EMC, shall be due and payable in accordance with each Party’s statement
instructions on or before the later of the twentieth (20th) Day of each Month, or the tenth (10th) Day after receipt of the statement or; if such Day is not a Business Day, then on the next Business Day. Each Party
shall make payments in immediately available funds by electronic funds transfer, or by other mutually agreeable method, to the account designated in writing by the other Party. Any non-disputed amounts (other than amounts for which payment may be
withheld pursuant to Section 13.5) not paid by the due date shall be deemed delinquent and shall accrue interest at the Interest Rate, such interest to be calculated from and including the due date to but excluding the date the delinquent
amount is paid in full. 
 13.4 Netting of Payments. The Parties hereby agree that they shall discharge mutual debts and payment obligations due and
owing to each other on the same date through netting, in which case all amounts owed by each Party to the other Party under this Agreement during the Billing Period, including any related interest, payments, and credits, shall be netted so that only
the excess amount remaining shall be paid by the Party who owes it. If no mutual debts or payment obligations exist and only one Party owes a debt or obligation to the other Party during the Monthly Billing Period, including but not limited to any
interest, payments, or credits, that Party shall pay such sum in full when due. 
 13.5 Disputes and Adjustments of Statements. A Party may, in good
faith, dispute the correctness of any statement or any adjustment to a statement, rendered under this Agreement or adjust any statement for any arithmetic or computational error within twenty-four (24) Months of the date the statement, or
adjustment to a statement, was rendered. If a statement or portion thereof, or any other claim or adjustment arising under this Agreement is disputed, the disputing Party shall provide written notice to the other Party (the “Billing Dispute
Notice”) which (a) states the good faith basis for the dispute, (b) specifies the amount in dispute (the “Disputed Amount”), if any, and (c) provides documentation reasonably supporting the determination of the Disputed
Amount. The disputing Party shall, at its option, (a) make payment to the other Party of the Disputed Amount under protest and thereafter shall be reimbursed by the other Party for any amount determined to be refundable after the resolution of
such dispute or (b) withhold one half (1/2) of the Disputed Amount and make payment to the other Party of the other one half (1/2) of the Disputed Amount. Payment to the other Party of one half (1/2) of the Disputed Amount shall
not relieve the disputing Party of the obligation to pay interest accrued at the Interest Rate from and including the date such payment was due to but excluding the date of such payment of any portion of such Disputed Amount withheld and determined
to be due and payable after the resolution of such dispute. Likewise, the other Party shall not be relieved of the obligation to pay interest accrued at the Interest Rate from and including the date such payment was made to but excluding the date of
reimbursement of any portion of such Disputed Amount paid and determined to be refundable after the resolution of such dispute. 
  

 69 

 In the event that a Party, by timely notice to the other Party, disputes the correctness of a statement
or portion thereof or any other claim or adjustment arising under this Agreement, the other Party shall promptly review the disputed statement or adjustment and shall notify the disputing Party, within forty-five (45) Days following receipt of
the Billing Dispute Notice, of the amount of any error or the amount of any payment or reimbursement that the disputing Party is required to make or is entitled to receive. Payments determined to be due by the disputing Party shall be included on
the next Monthly statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date paid. Reimbursements determined to be due from the other Party shall be included on the next Monthly
statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date reimbursed. If the disputing Party disagrees with the other Party’s resolution of any dispute, then the Parties shall
submit the dispute for resolution in accordance with Article 14. 
 Inadvertent overpayments shall be returned upon request or deducted
by the Party receiving such overpayment from subsequent payments, with interest accrued at the Interest Rate from and including the date of such overpayment to but excluding the date repaid or deducted by the Party receiving such overpayment. Any
dispute with respect to a statement is waived unless the other Party is notified in accordance with this Section 13.5 within twenty-four (24) Months after the statement is rendered or any adjustment to the statement is made. Neither Party
shall have the right to challenge any statement, to invoke arbitration of the same or to bring any court or administrative action of any kind questioning the propriety or any other aspect of such statement after a period of twenty-four
(24) Months from the date the statement was rendered; provided, however, that in the case of a statement containing estimates, such twenty-four (24) Month period shall run from the date the statement is adjusted to reflect the actual
amounts due. 
 13.6 Records and Audits. Each Party shall keep such records and documents as may be needed to afford a clear and complete history of
all transactions under this Agreement, and the cost information used to calculate the charges for such transactions, for twenty-four (24) Months following the Month in which such transaction occurs. In addition, during such twenty-four
(24) Month period, EMC shall have the right to audit all records, including phone and computer records, related to Duke’s performance of its obligation not to adversely distinguish against EMC’s Native Load under Section 4.3.3,
Section 6.2, and Section 9.4.2 of this Agreement. If a Party initiates an audit through a notice to the other Party within the time period provided herein, the records and documents related to such audit are required to be maintained under
this Section 13.6, then the other Party will retain such records and documents until such audit is complete. If a Party issues an Original Notice pursuant to Article 14, then the Parties will retain the records and documents relating to such
dispute until the resolution of such dispute. In maintaining such records and documents, EMC and Duke may rely upon the logs and other meter information routinely recorded by Transmission Providers or utilities responsible for coordination of the
purchases and sales. During such twenty-four (24) Month period, either Party, or any Representatives of such Party, shall have the right, at its sole expense and during normal working Hours, to examine the records of the other Party, including
documents and records held by third parties, to the extent reasonably necessary to verify the accuracy of any statement, charge, or computation made pursuant to this Agreement. The Party requesting the audit shall pay the costs associated with any
independent auditor. Upon the request of the auditing Party, the document custodian of the other Party shall certify to the auditing Party that, 
  

 70 

 to the best of such person’s knowledge after reasonable investigation, the documents and records supplied are true
and complete and, in the case of copies, are true, complete and correct copies of the original documents requested by the auditing Party. 
 13.6.1 Procedures. EMC may make a written request for Duke to provide access to documents and records to verify the accuracy of any statement, charge or computation made pursuant to this Agreement. Within ten (10) Business Days
of the receipt of a written request from EMC, Duke shall either provide EMC, or its Representative, with access to the documents and records which are the subject of the written request or provide EMC with copies of the original documents and
records. If Duke elects to provide EMC, or its Representative, with access to the documents and records requested by EMC, EMC or its Representative shall be permitted to make, at its own expense, copies of the documents and records to which it or
its Representative has been provided access. Any copies made by EMC or its Representative shall be subject to the confidentiality provisions set forth in Section 16.6. If Duke is unable to provide EMC with access or copies within ten
(10) Business Days of the receipt of EMC’s written request because it is unable to locate or gain access to such documents and records after reasonable investigation, Duke shall, within ten (10) Business Days of the receipt of such
written request, provide EMC with notice describing the reasons for its failure to provide access to or copies of the documents and records, its efforts to obtain such documents and records, and its best estimate of the time in which EMC will be
permitted access to or provided copies of such documents and records. The twenty-four (24) Month period provided for in Section 13.5 shall be tolled from the date Duke gives notice describing the reasons for its failure to provide access
to or copies of the documents and records until Duke shall have (i) provided EMC with copies or access to all documents and records specified in EMC’s written request or (ii) Duke’s document custodian shall have certified, that
to the best of his knowledge after reasonable investigation that such document does not exist or Duke cannot locate or produce such document or records. 
 13.6.2 Adjustments Resulting from Audits. If any audit or examination under this Section 13.6 reveals any inaccuracy in any statement, the necessary adjustments in such statement and the payments thereof
shall be made promptly and shall accrue interest at the Interest Rate from the date the overpayment or underpayment was made until paid; provided, however, that no adjustment for any statement or payment shall be made unless objection to the
accuracy thereof was made prior to the lapse of twenty-four (24) Months from the rendition thereof, and thereafter any objection shall be deemed waived. 
 13.6.3 Confidentiality. The auditing Party shall keep confidential any information obtained in the audit. If requested, a Party shall provide to the other Party statements evidencing the quantity of electric
energy provided under this Agreement for up to the prior twenty-four (24) Months. If an audit is requested with respect to any records held by the a Party or a third party and those records cannot be disclosed to the requesting Party as a
result of a confidentiality obligation, then to the extent legally permissible, the auditing Party shall select an independent auditor to perform the audit consistent with the Parties’ rights under this Agreement and with such confidentiality

 Article 14 
 Dispute Resolution 
 14.1 Arbitration. Except as otherwise provided below, any dispute arising out of or in
connection with this Agreement or its performance that cannot be resolved after good faith discussions and negotiations between the Parties as set forth in Section 14.2 shall be submitted to binding arbitration. A dispute with respect to
whether a Material Adverse Ruling meets the materiality standard specified in Section 2.3.2.2(c)(1) or (c)(2) shall be subject to dispute resolution pursuant to Section 2.3.2.2.2. A dispute with respect to an invoice shall first be subject
to the procedures set forth in Section 13.5, and if such dispute is not resolved in accordance with such procedures, then such dispute shall be submitted to binding arbitration in accordance with this Article 14. Any arbitration commenced
under this Article 14 shall be conducted in accordance with the North Carolina Arbitration Act, N.C.G.S. Section 1-567 et seq., and the non-administered arbitration rules and procedures of the CPR Institute for Dispute Resolution
(“CPR”) in effect at the time arbitration is commenced, except where specifically modified by this Agreement. 
 14.2 Negotiation and Notice of
Arbitration. Prior to initiating arbitration hereunder, a Party shall provide the other Party with written notice of the dispute, a proposed means for resolving the same, and support for the Party’s position (“Original Notice”).
Thereafter, Representatives of the Parties shall meet in person to discuss the matter and attempt in good faith to reach a negotiated resolution of the dispute. The Parties agree to provide and exchange supporting facts, records and information
regarding the dispute (including calculation and bases) as part of the good faith negotiations. If the Parties have not agreed upon a resolution of the dispute within thirty (30) Days after the provision of the Original Notice or such other
time period as the Parties may agree in writing to allow for discussions and negotiation (“Negotiation Period”), then at any time after the end of the Negotiation Period, a Party may provide written notice to the other declaring an impasse
(“Impasse Notice”) and initiating binding arbitration in accordance with the further provisions of this Article 14. A Party providing an Impasse Notice shall also contemporaneously notify all entities within the EMC Group of the
provision of its Impasse Notice. 
 14.3 Individual, Joint or Consolidated Arbitration. If, within thirty (30) Business Days of EMC’s
provision of an Impasse Notice, Blue Ridge and/or Rutherford also provides an Impasse Notice relating to substantially the same issue as raised by EMC’s Impasse Notice, or if Duke contemporaneously provides each of EMC, Blue Ridge and/or
Rutherford an Impasse Notice relating to substantially the same issue, then each entity within the EMC Group shall have ten (10) Business Days following the expiration of such thirty (30) Business Day period to provide written notification
to Duke stating whether or not such entity will voluntarily proceed in a joint or combined arbitration. 
 If EMC and one or more of the
entities within the EMC Group that have provided or received Impasse Notices within the specified time period relating to substantially the same issue elect to proceed individually or in more than one arbitration proceeding, Duke shall have the
right to file a motion to consolidate such Impasse Notices with EMC’s Impasse Notice in a single proceeding. The motion to consolidate such Impasse Notices shall be served within ten (10)
  

 72 

 Business Days of the date when each entity within the EMC Group has provided notice as to whether or not it will
voluntarily proceed in a consolidated arbitration. Duke’s motion to consolidate shall be decided in the first commenced arbitration by one arbitrator (if the Streamlined Arbitration Process is used) or one (1) arbitration panel (if the
Standard Arbitration Process is used), provided that the arbitrator(s) shall satisfy the qualifications required pursuant to the third sentence of Section 14.6.1(1) or Section 14.6.2(2), as applicable, with respect to all entities in the
arbitration proceedings that are the subject of the motion to consolidate. If Impasse Notices are simultaneously given by EMC and one or more other entities within the EMC Group, then Duke shall have sole discretion to designate which of the Impasse
Notices shall be treated as the first given for purposes of determining which arbitrator(s) shall decide the motion to consolidate, and shall provide written notice of such designation in the motion to consolidate arbitrations. The procedures set
forth in Sections 14.6.1 and 14.6.2 for each arbitration proceeding in which the motion to consolidate was not filed shall be held in abeyance pending the decision on the motion to consolidate by the arbitrator(s) in the arbitration proceeding in
which the motion to consolidate was filed. 
 In determining whether consolidation of one or all is appropriate, the arbitrator(s) shall
consider whether the same or substantially similar issue or issues will be subject to the arbitration(s); EMC’s reasons for opposing consolidation and Duke’s reasons for seeking consolidation; and the fundamental fairness and efficiency in
proceeding individually, jointly or consolidated. The arbitrator(s) decision on the motion to consolidate shall be binding on the Parties and not subject to appeal. 
 In the event the motion to consolidate is denied (unless otherwise agreed by the Parties and the other entities of the EMC Group that have provided or received such Impasse Notices), the arbitrations shall each
proceed, subject to resolution of scheduling issues, with no arbitration being stayed as a result of the denial of the motion. In the event the motion to consolidate is granted, each entity within the EMC Group, other than the entity which is a
party to the proceeding in which the motion to consolidate was filed, shall move for dismissal of the respective arbitration actions in which it is a party. 
 14.3.1 Individual Treatment of EMC in Joint or Consolidated Arbitration. For purposes of joint or combined arbitration, all of the entities within the EMC Group participating in the proceeding shall be treated
as one (1) Party for purposes of Article 14, with the following exceptions. First, EMC shall be treated as a separate Party for purposes of Selection of Arbitration Process set forth in Section 14.4. Second, EMC may reach its own
independent, voluntary resolution with Duke and may pursue its own strategy and prosecute its case with its own legal counsel in the joint or combined arbitration. Third, EMC will be treated as a separate Party for purposes of discovery in
Section 14.6.1(4) or 14.6.2(4). Fourth, EMC will be treated as a separate Party for purposes of a Submission and for the adoption of the resolution and the associated monetary amount with respect to the ultimate decision of the arbitrator(s).
Fifth, EMC will be treated as a separate Party for purposes of the third sentence of Section 14.6.1(1) and Section 14.6.2(2). 
 14.4 Selection
of Arbitration Process. No later than thirty (30) Days following receipt of the Impasse Notice, or any longer time period as agreed to by the Parties, the Parties shall agree on which arbitration process specified herein to use: either the
Standard Arbitration Process or the 
  

 73 

 Streamlined Arbitration Process. Should the Parties fail to agree on the arbitration process within thirty (30) Days
following receipt of the Impasse Notice, then the Standard Arbitration Process shall be used; provided however, that the Streamlined Arbitration Process shall be used for any dispute where the damages in dispute or other monetary value at stake is
alleged to be two hundred fifty thousand dollars ($250,000) or less for EMC or Duke, or in a joint or combined proceeding two hundred and fifty thousand dollars ($250,000) or less for each entity within the EMC Group that is participating in the
proceeding. If the damages in dispute or other monetary value at stake in a combined proceeding is alleged to be two hundred fifty thousand dollars ($250,000) or less for EMC and at least one (1) other of the entities within the EMC Group
participating in a joint or combined proceeding, the Streamlined Arbitration Process shall be used upon the request of either Party (or any of the other entities within the EMC Group participating in the proceeding) made within thirty (30) Days
following the receipt of the Impasse Notices. 
 14.5 Initiation of Arbitration. Unless otherwise agreed by the Parties and except as provided for in
Section 14.3, arbitration shall be deemed to be initiated when the arbitration process is agreed upon or otherwise determined pursuant to Section 14.4 (“Selection Date”). 
 14.6 Arbitration Processes. 
 14.6.1 Standard
Arbitration Process. The following shall be the process that is used, in accordance with this Article 14, as the Standard Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the
purposes of that arbitration alone modify or forego any procedural requirement or rule specified hereunder as part of the Standard Arbitration Process: 
 (1) Selection of Arbitrators. The Party initiating arbitration shall nominate one (1) arbitrator no later than fifteen (15) Days following the Selection Date. The other Party shall nominate one
(1) arbitrator no later than thirty (30) Days after the Selection Date. Each of the two Party-nominated arbitrators shall be unaffiliated with any of the Parties or their predecessors or Affiliates; shall not be current or former employees
of the nominating Party or its predecessors or Affiliates and shall be without material financial alliance with the nominating Party or its predecessors or Affiliates such that said arbitrator is able to participate in the arbitration without
evident partiality or actual bias in favor of the nominating Party; unless such pecuniary interest or affiliation is expressly acknowledged and waived by all Parties. The two (2) arbitrators shall jointly appoint a third (3rd), neutral arbitrator within thirty (30) Days after the
nomination of the second (2nd) arbitrator. The neutral arbitrator shall be the chairperson of the tribunal.
This thirty (30) Day period may be extended to sixty (60) Days by agreement of both Parties. If the two (2) arbitrators are unable to agree on a third (3rd) arbitrator within the specified time period, then a third
(3rd) arbitrator shall be selected by the CPR with due regard given to the selection criteria herein and in the subsequent subsections of Article 14 and input from the Parties and other arbitrators. The Parties shall request CPR to
complete selection of the third (3rd) arbitrator no later than thirty (30) Days following their request
for selection of the arbitrator. Costs charged by CPR for this service shall be borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3,
the costs charged by CPR shall be 
  

 74 

 borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that
participate in such consolidated arbitration. In the event CPR should fail to select the third (3rd) arbitrator
within thirty (30) Days following the Parties’ request for selection of the arbitrator, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the third (3rd) arbitrator. Due regard shall be given to the selection criteria and input from the Parties and other arbitrators. Each of the arbitrators shall
take an oath of neutrality. 
 (2) Additional Qualifications of Arbitrators. Unless otherwise agreed to by the Parties,
each of the arbitrators shall be competent and experienced in matters involving the electricity business in the United States. Such experience shall be conclusively demonstrated by ten (10) years or more of electric industry experience as a
practicing attorney or other experience or expertise as agreed to by the Parties. 
 (3) Replacement of Arbitrators. If
prior to the conclusion of the arbitration any arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein shall be appointed in the manner and timeframe (such timeframe
starting anew following the unavailability of the arbitrator to be replaced) described in Section 14.6.1(1) above. 
 (4)
Discovery. Discovery and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, as determined by a majority of the arbitrators. Each Party shall have the right to
propound up to ten (10) interrogatories, the right to request relevant documents and records, conduct depositions (including depositions of experts), designate experts, and obtain the opinion of opposing experts. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit by overnight
delivery and electronic mail to the arbitrators a precise statement of the dispute, a proposed resolution of the dispute, including a monetary amount and the supporting calculations if applicable, and the factual and/or legal support therefor (the
“Submission”). The next Business Day the Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by
overnight delivery and electronic mail to the other Party and the arbitrators a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) sixty
(60) Days following selection of the third (3rd) arbitrator, (ii) forty-five (45) Days after all pre-hearing discovery has been completed, or (iii) forty-five (45) Days after the issuance of the arbitrators’ decision denying a motion to consolidate
pursuant to Section 14.3, at which the Parties shall present such evidence, argument, and witnesses as they may choose. Prior to the beginning of the hearing, the Parties may submit a joint statement of undisputed facts and/or issues to be
resolved, if the Parties so agree to submit such statement or if the arbitrators order submission of the statement. If the Parties agree, or if allowed by a majority of the arbitrators, the Parties each may submit a post-hearing brief to the
arbitrators within ten (10) Business Days of completion of the hearing. No reply briefs shall be allowed unless otherwise permitted by a majority of the arbitrators. 
  

 75 

 14.6.2 Streamlined Arbitration Process. The following shall be the process that is used, in
accordance with this Article, as the Streamlined Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the purposes of that arbitration alone modify or forego any procedural requirement or
rule specified hereunder as part of the Streamlined Arbitration Process: 
 (1) Selection of Arbitrator. No later than
thirty (30) Days following the Selection Date, the Parties shall agree upon a single arbitrator to conduct the arbitration. If the Parties are unable to agree on an arbitrator, then the arbitrator shall be selected by the CPR with due regard
given to input from the Parties and in conformity with the qualifications specified herein. The Parties shall request CPR to complete selection of the arbitrator no later than thirty (30) Days following their request for selection of an
arbitrator. Costs charged by CPR for this service shall be borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by
CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that participate in such consolidated arbitration. In the event CPR should fail to select the arbitrator within seventy-five (75) Days
after the Selection Date, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the arbitrator. Due regard shall be given to the selection criteria and input from the Parties. The arbitrator shall
take an oath of neutrality. 
 (2) Qualification of the Arbitrator. The arbitrator shall be unaffiliated with any of
the Parties or their predecessors or Affiliates, such that the arbitrator: 
 (a) Shall not be a current or former employee,
advisor, attorney or consultant; 
 (b) Shall be without material financial alliance, such that said arbitrator is able to
participate in the arbitration without evident partiality or bias, unless such pecuniary interest or affiliation is expressly acknowledged and waived by all Parties; 
 (c) Shall be competent in matters involving the electricity business in the United States and shall have ten (10) years or more of
electric industry experience as a practicing attorney or such other experience or expertise as agreed by the Parties; and 
 (d) Shall take an oath of neutrality. 
 (3) Replacement of Arbitrator. If prior to the conclusion of the
arbitration the arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein, shall be appointed in the manner and timeframe (such timeframe starting anew following the
unavailability of the arbitrator to be replaced) described in Section 14.6.2(1) above. 
 (4) Discovery. Discovery
and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, 
  

 76 

 as determined by the arbitrator. Each Party shall have the right to propound up to ten
(10) interrogatories, the right to request relevant documents and records, conduct at least three (3) depositions, in addition to obtaining discovery of the opinions of any experts and the right to depose any experts (which are not
included in the three (3) depositions above). Additional discovery may be conducted only as allowed by the arbitrator or agreed by the Parties. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit a Submission by overnight delivery and electronic mail to the arbitrator. The next Business
Day, the Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by overnight delivery and electronic mail to the
other Party and the arbitrator a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) forty-five (45) Days following selection of the
arbitrator, (ii) forty-five (45) Days after all pre-hearing discovery has been completed, or (iii) forty-five (45) days after the issuance of the arbitrator(s)’ decision denying a motion to consolidate pursuant to
Section 14.3, at which the Parties shall present such evidence, witnesses, and argument as they may choose. Unless otherwise ordered by the arbitrator, at least two (2) Days prior to the beginning of the hearing, the Parties may submit a
joint statement of undisputed facts and/or issues to be resolved if the Parties so agree to submit such statement or if the arbitrator orders submission of the statement. If the Parties agree, or if allowed by the arbitrator, the Parties may each
submit a post-hearing brief to the arbitrator within ten (10) Business Days of completion of the hearing. No reply briefs shall be allowed unless otherwise permitted by the arbitrator. 
 14.7 Decision. The arbitrator (if the Streamlined Arbitration Process is used) or a majority of the arbitrators (if the Standard Arbitration Process is used)
shall render his or their decision in favor of one Party or the other by adopting the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The arbitrator(s) must determine the prevailing Party by
interpreting the meaning and intent of the language of this Agreement, applying the applicable Law to the relevant facts and selecting the arbitration ruling proposed by the Parties that most closely correlated to their decision based upon this
Agreement, the applicable Law and the relevant facts. In rendering the decision, the arbitrator(s) shall interpret and apply the terms and conditions of this Agreement, and consider any relevant evidence and testimony, but shall not have the power
to add to or modify any provision of this Agreement or to recommend any additions or modifications or to render a decision that does not adopt the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The
arbitrator(s) shall render a decision within thirty (30) Days following the later of the conclusion of the hearing or the submission of post-hearing briefs. The decision shall be rendered in writing and shall be final and binding upon the
Parties. The decision may be filed in a court of competent jurisdiction, confirmed and may be enforced by any Party as a final judgment in such court, but shall have no precedential effect on future arbitrations under or arising out of this
Agreement except for purposes of enforcement in a court of competent jurisdiction or for the assertion of collateral estoppel/issue preclusion or res judicata/claim preclusion in another proceeding. The Parties expressly acknowledge that no
appeal of the arbitrator’s (or arbitrators’) decision shall be allowed. Except as provided in Section 16.6.4 of this Agreement, the arbitrator(s) shall have no authority to award special, exemplary, punitive, or consequential damages.

  

 77 

 14.8 Expenses. The compensation and expenses of the arbitrator(s) shall be chargeable to and borne one-half
(1/2) by Duke and one-half (1/2) by EMC; provided, that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by
the entities within the EMC Group that participate in such consolidated arbitration; provided, however, that each Party shall bear the compensation and expenses of its own counsel and any retained or expert witnesses. Any costs incurred by a Party
in seeking judicial enforcement of any final decision rendered by arbitration conducted under this Article 14 shall be chargeable to and borne exclusively by the Party against whom such court order is obtained. It is expressly acknowledged that the
failure of the entities within the EMC Group that participate in a consolidated arbitration to reach agreement on the allocation of costs among such entities shall not increase Duke’s share of the costs incurred under this Section 14.8 or
Sections 14.6.1(1) or 14.6.2(1) above one-half (1/2) of the total costs at issue. 
 14.9 Effect of Dispute Resolution Procedures. The initiation
of the dispute resolution procedures under this Article 14 shall not affect the Parties’ respective obligations and rights under this Agreement during the pendency of any such procedures. 
 14.10 Confidentiality. The existence, contents, or results of any arbitration proceeding under this Article 14 shall be deemed to be Confidential Information and
shall be subject to the confidentiality provisions set forth in Section 16.6. 
 Article 15 
 Credit and Collateral Requirements 
 15.1 Posting of
Collateral. To protect either Party against potential default of payment or performance, any Party that experiences a Material Adverse Change (“MAC”) shall post as collateral an amount equal to the two (2) highest Months of
Duke’s billings to EMC for the previous twelve (12) Months. Such collateral shall be provided by the Party experiencing the MAC in cash, depository agreements, or letters of credit from a financial institution reasonably acceptable to the
Party not experiencing the MAC within three (3) Business Days after the date on which the MAC occurs. Any such depository agreement or letter of credit shall be in a form satisfactory to the Party not experiencing the MAC in its reasonable
discretion. A financing institution participating in a depository agreement or providing a letter of credit entered into for purposes of this Section 15.1 shall be deemed reasonably acceptable by the Party not experiencing the MAC if it has and
maintains a minimum long term credit rating of A- or better from S&P, A3 or better from Moody’s or A- or better from Fitch Ratings, or is with or from CFC and/or CoBank. 
 15.2 Material Adverse Change. Duke shall be deemed to have experienced a MAC if its unsecured, senior long-term debt obligations not supported by third party credit enhancements are rated below BBB- by S &
P and below Baa3 by Moody’s. EMC shall be deemed to have experienced a MAC (a) if it fails to meet the then-current Debt Service Coverage Ratio required 
  

 78 

 of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three
(3) Years, and (b) the then-current Times Interest Earned Ratio required of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three (3) Years. The failure by either Party to timely
fulfill a payment or reimbursement obligation, including, in the case of Duke a failure to pay Cover Costs, under this Agreement also shall constitute a MAC by that Party. 
 15.3 Continuing Nature of Collateral Requirement. The Party experiencing the MAC must continue to post the collateral until the MAC is cured. The Party not experiencing the MAC shall have the right to draw
upon, use, and dispose of all collateral that is posted under Section 15.1, if the Party experiencing the MAC fails to fulfill any of its payment or reimbursement obligations, including, in the case of Duke a failure to pay Cover Costs, under
this Agreement, and such failure constitutes an Event of Default. In the event any collateral is drawn upon by the Party not experiencing the MAC in accordance with the provisions of Section 15.5, the Party experiencing the MAC shall within
three (3) Business Days fully replenish the collateral to the monetary amount required by Section 15.1. 
 15.4 Interest on Cash Used as
Collateral. Any interest earned on collateral held under a depository agreement with a financial institution shall be paid to the Party posting the collateral in accordance with the terms of the depository agreement. If cash collateral is
posted, the Party holding the cash collateral shall pay interest to the Party posting the cash collateral at the Federal Funds Effective Rate. The Federal Funds Effective Rate is the rate for that Day opposite the caption “Federal Funds
(Effective)” as set forth in the weekly statistical release designated as H.15(519), or any successor publication published by the Board of Governors of the Federal Reserve System. The Party posting the cash collateral shall invoice the Party
holding the cash collateral for interest accrued during the previous Month and the Party holding the cash collateral shall pay such amount within ten (10) Days of receipt of such invoice. 
 15.5 Grant of Security Interest/Remedies. To secure their obligations under this Agreement, any Party posting collateral under Section 15.1 hereby grants to
the Party not experiencing the MAC a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral, cash equivalents collateral and any and all proceeds resulting therefrom or the
liquidation thereof, whether now or hereafter held by, on behalf of, or for the benefit of, that Party, and the posting Party agrees to take such action as the non-posting Party reasonably requires in order to perfect the non-posting Party’s
first-priority security interest in, and lien on (and right of setoff against), such collateral and any and all proceeds resulting therefrom or from the liquidation thereof. Upon or any time after the occurrence or deemed occurrence and during the
continuation of an Event of Default, the Non-Defaulting Party may do any one or more of the following: (i) exercise any of the rights and remedies of a secured party with respect to all collateral, including any such rights and remedies under
Law then in effect; (ii) exercise its rights of setoff against any and all property of the Defaulting Party in the possession of the Non-Defaulting Party or its agent; (iii) draw on any outstanding letter of credit issued for its benefit;
and (iv) liquidate all collateral then held by or for the benefit of the Non-Defaulting Party free from any claim or right of any nature whatsoever of the Defaulting Party, including any equity or right of purchase or redemption by the
Defaulting Party. The Party drawing upon the collateral shall apply the collateral drawn upon or otherwise realized upon the exercise of any rights or remedies granted under this Section 15.5, to reduce the obligations of 
  

 79 

 the Party posting the collateral under this Agreement (the posting Party remaining liable for any amounts owing after
such application), and to return any surplus collateral or proceeds remaining after the posting Party’s obligations are satisfied in full. 
 15.6
Notice, Information. Each Party shall provide the other Party written notice within two (2) Business Days of the occurrence of an MAC affecting the notifying Party or of the occurrence of any event that may reasonably cause a MAC. Duke
shall provide EMC a copy of Duke’s annual report, and any amendments thereto, within thirty (30) Days after the issuance/filing with the Securities and Exchange Commission of such report or amendment. EMC shall provide Duke with (a) a
copy of EMC’s RUS Form 7 each Year, and any amendments to such Form 7, within thirty (30) Days after the filing of such report or amendment with RUS, and (b) the annual Debt Service Coverage Ratio and Times Interest Earned Ratio
required of EMC by RUS for the Year in which the Effective Date occurs and for the two (2) immediately preceding Years.

effective date of an assignment that satisfies the requirements of subpart (b) above. 
 16.2.1.2 EMC shall not assign this Agreement or
its rights hereunder without the prior written consent of Duke, which consent shall not be unreasonably withheld; provided, however, that EMC may, without the consent of Duke, (a) transfer, sell, pledge, encumber or assign this Agreement or the

approval of the other Party, may (i) cause the interest in this Agreement of the Party who made the Assignment for Security to be sold, assigned, transferred or otherwise disposed of to a third party pursuant to the terms governing such
Assignment for Security, or (ii) if the Administrator or other secured party first acquires this Agreement, sell, assign, transfer or otherwise dispose of this Agreement to a third party; provided, however, that in either case the Party who
made the Assignment for Security is in default of its obligations to the Administrator or other secured party that are secured by such security interest. 
  

	16.3	Liability and Indemnification. 

 16.3.1
Indemnity. Each Party shall indemnify, defend, and hold harmless the other Party from and against: 
 (1) Any Claims
arising from or out of any event, circumstance, act, or incident first occurring or existing during the period when control and title to any electric energy is vested in such Party as provided in Section 4.5, and

 Notwithstanding the foregoing, no Party will be required to indemnify, defend, or hold harmless any other Party from any losses or Claims under this

 16.3.2 Liability Limitations. 
 16.3.2.1 Limitation of Remedies. THE PARTIES CONFIRM THAT THE EXPRESS REMEDIES AND
MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT SATISFY THE ESSENTIAL PURPOSES HEREOF. FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND
EXCLUSIVE REMEDY, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR 
  

 86 

 DAMAGES AT LAW OR IN EQUITY ARE WAIVED REGARDLESS OF THE FAULT, NEGLIGENCE, OR STRICT LIABILITY OF THE PARTY WHOSE
LIABILITY IS RELEASED OR LIMITED THEREBY. 
 IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY HEREIN PROVIDED, AND EXCEPT AS OTHERWISE
EXPLICITLY PROVIDED IN SECTION 16.6.4, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES (INCLUDING INTEREST AS PERMITTED BY APPLICABLE LAW) ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY
AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED (EXCEPT AS PROVIDED IN SECTION 16.29). 
 UNLESS EXPRESSLY HEREIN
PROVIDED, (INCLUDING AS PROVIDED IN SECTION 16.6.4) NO PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, MULTIPLE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR IN
CONTRACT UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY
PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT, OR CONCURRENT, OR ACTIVE OR PASSIVE. 
 16.3.2.2 Disclaimer. EXCEPT AS EXPRESSLY SET
FORTH IN THIS AGREEMENT, EACH PARTY, WITH RESPECT TO THE SUPPLY OF ELECTRIC ENERGY AND CAPACITY TO THE OTHER, EXPRESSLY NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN OR ORAL, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION,
ANY REPRESENTATION OR WARRANTY WITH RESPECT TO CONFORMITY TO MODELS OR SAMPLES, MERCHANTABILITY, OR FITNESS FOR ANY PARTICULAR PURPOSE. 
 16.3.2.3 Duty to Mitigate. Each Party agrees that is has a duty to mitigate damages, and each covenants that it shall use commercially reasonable efforts to minimize any damages it may incur as a result of the other Party’s
performance or nonperformance of this Agreement. 
 16.4 Force Majeure. Unless otherwise provided by this Agreement, the term “Force
Majeure” means an event or circumstance that: (i) prevents the Party claiming to be affected by it (the “Claiming Party”) from performing its obligations in whole or in part under this Agreement; (ii) is not within the
reasonable control of the Claiming Party, or the result of the negligence of the Claiming Party, and (iii) by the exercise of due diligence, the Claiming Party is unable to overcome in a commercially reasonable manner, and, without limiting the
scope of the definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court
order or Governmental Authority or arbitration award (so long as the Claiming Party has not sought or has opposed, to the extent reasonable, such actions or restraints). To the extent that the Claiming Party is prevented by Force Majeure from
carrying 
  

 87 

 out, in whole or part, its obligations hereunder and such Party gives notice and details of the Force Majeure to the
other Party (the “Non-Claiming Party”) as soon as practicable, then the Claiming Party shall be excused from the performance of its obligations other than the obligation to make payments then due or becoming due in respect to performance
prior to the Force Majeure, except as otherwise explicitly provided in this Agreement. The Claiming Party shall remedy the Force Majeure event with all reasonable dispatch. The Non-Claiming Party shall not be required to perform or resume
performance of its obligations to the Claiming Party corresponding to the obligations of the Claiming Party excused by Force Majeure during the period that such Force Majeure remains in effect. Duke shall not adversely distinguish between EMC’s
Native Load and Duke’s Native Load in claiming an event of Force Majeure. 
 16.5 Events of Default and Remedies. 
 16.5.1 Events of Default. For the purposes of this Agreement, an “Event of Default” means, with respect to a Party (a “Defaulting
Party”), the occurrence of any of the following: 
 (1) The failure to make, when due, any payment or reimbursement
required by this Agreement (including any amounts to be credited by one Party to the other Party) or to post or maintain collateral required by this Agreement, if such failure is not remedied within three (3) Business Days after receipt of
written notice of such failure is given to the Defaulting Party by the other Party (“Non-Defaulting Party”). For the purposes of this Section 16.5.1(1), withholding one half (1/2) of a Disputed Amount in accordance with
Section 13.5 shall not constitute failure to make, when due, a payment; 
 (2) Any representation or warranty made by
such Party herein is false or misleading in any material respect when made or when deemed made or repeated; 
 (3) The failure
to perform any material covenant or material obligation set forth in this Agreement (except to the extent constituting a separate Event of Default under this Section 16.5), if such failure is not remedied within three (3) Business Days
after receipt of written notice thereof to the Defaulting Party, provided, that a Party’s failure to perform its obligations under Section 16.1.2.1(iii) or Section 16.1.2.2(iv) shall not in and of itself constitute a material failure
to perform a material covenant or material obligation unless such failure, in the case of Duke, results in a substantial and continuing degradation in reliability of service hereunder or, in the case of EMC, results in a substantial and continuing
degradation in performance hereunder; 
 (4) Such Party becomes Bankrupt; 
 (5) The loss of any authorization from Governmental Authorities necessary to perform its obligations hereunder in accordance with the
terms of this Agreement; 
 (6) Such Party consolidates or amalgamates with, or merges with or into, or transfers all or
substantially all of its assets to, another entity and, at the 
  

 88 

 time of such consolidation, amalgamation, merger, or transfer, the resulting, surviving, or transferee
entity fails to assume all of the obligations of such Party under this Agreement to which it or its predecessor was a party by operation of law or pursuant to an agreement reasonably satisfactory to the other Party; 
 (7) The occurrence and continuation of a default, event of default, or other similar condition or event that under one or more agreements
or instruments, individually or collectively, relating to indebtedness for borrowed money in an aggregate amount of not less than nine million dollars ($9,000,000) in the case of EMC or one hundred fifty million dollars ($150,000,000) in the case of
Duke, that results in the Party’s indebtedness under such agreements or instruments to become immediately due and payable; and 
 (8) With respect to such Party’s guarantor, if any: 
  

	 	(a)	if any representation or warranty made by a guarantor in connection with this Agreement is false or misleading in any material respect when made or when deemed made or repeated;

  

	 	(b)	the failure of a guarantor to make any payment required or to perform any other material covenant or obligation in any guaranty made in connection with this Agreement and such
failure shall not be remedied within three (3) Business Days after written notice; 

  

	 	(c)	a guarantor becomes Bankrupt; 

  

	 	(d)	the failure of a guarantor’s guaranty to be in full force and effect for purposes of this Agreement (other than in accordance with its terms); or 

  

	 	(e)	a guarantor shall repudiate, disaffirm, disclaim, or reject, in whole or in part, or challenge the validity of any guaranty. 

 16.5.2 Notice of Event of Default. In the event a Party becomes aware of any event or circumstance that constitutes an Event of Default, such
Party shall promptly notify the other Party in writing and by telephone. 
 16.5.3 Effect of Event of Default. If at any time an Event
of Default with respect to a Defaulting Party has occurred and is continuing, the other Party (the “Non-Defaulting Party”) may do one or more of the following: 
 (1) If an Event of Default under Section 16.5.1(1) persists for ten (10) Days or longer, terminate this Agreement in accordance
with the notification required pursuant to Sections 2.3.2.1 and 2.3.3 of this Agreement; or 
  

 89 

 (2) If an Event of Default (other than an Event of Default under Section 16.5.1(1))
persists for sixty (60) Days or longer, terminate this Agreement in accordance with Sections 2.3.2.1 and 2.3.3 of this Agreement, provided, however, that if the Defaulting Party is diligently pursuing cure, but such Event of Default is not
capable of being cured within sixty (60) Days, then the period for the Defaulting Party to cure such Event of Default shall be extended from sixty (60) Days to one hundred eighty (180) Days before the Non-Defaulting Party may exercise
its right to terminate this Agreement pursuant to this Section 16.5.3(2). 
 16.5.4 Enforcement of Remedies. The Non-Defaulting
Party may exercise any rights or remedies available at law or equity, subject to the provisions of Article 14 and Sections 15.5 and 16.3 of this Agreement. No delay or failure on the part of a Non-Defaulting Party to exercise any right or
remedy to which it may become entitled on account of an Event of Default shall constitute an abandonment of any such right, and the Non-Defaulting Party shall be entitled to exercise such right or remedy at any time during the continuance of an
Event of Default notwithstanding any delay in enforcing such right. No waiver of any Event of Default shall constitute a waiver of any later Event of Default; all such waivers shall be in writing and shall in no circumstance be deemed effective
unless such waiver is made in writing. All of the remedies and other provisions of this Section 16.5 shall be without prejudice and in addition to any right of setoff, recoupment, combination of accounts, lien, or other right to which any Party
or any of its Affiliates is at any time otherwise entitled, whether by operation of law or in equity, under contract, or otherwise. 
  

	16.6	Confidential Information. 

 16.6.1 Prior
Confidentiality Agreements Unaffected. Any preexisting confidentiality agreements entered into by the Parties pertaining to the negotiation and development of this Agreement shall survive by their terms and shall not be considered modified by
this Agreement. 
 16.6.2 Authorized Disclosure. Each Party agrees to preserve, to the maximum extent permitted by Law, the
confidentiality of Confidential Information supplied to it by the other Party either during the negotiations leading to this Agreement or during the course of implementing, performing or winding up this Agreement. A Party may disclose Confidential
Information received from the other Party to the receiving Party’s Affiliates, auditors, attorneys, consultants, advisors, persons providing financing to the receiving Party, other entities in the EMC Group that have entered into substantially
similar agreements, and to other third parties as may be necessary for the receiving Party to perform its obligations under this Agreement, provided that any such persons agree in writing to be bound by the confidentiality provisions of this
Agreement. Notwithstanding anything contained in this Section 16.6, Confidential Information may be disclosed to any Governmental Authority requiring such Confidential Information, provided that: (i) such Confidential Information is
submitted under applicable provisions, if any, for confidential treatment by such Governmental Authority; (ii) prior to such disclosure, the Party who supplied the information is given notice of the disclosure requirement (if time permits and
the other Party’s counsel determines that such notice is permitted by Law) so that it may take at its own risk and expense whatever action it deems appropriate, including intervention in any proceeding and the seeking of an injunction to
prohibit such disclosure; and (iii) the Party subject to the Governmental Authority endeavors to protect the confidentiality of 
  

 90 

 any Confidential Information to the extent reasonable under the circumstances and to use its good faith efforts to
prevent the further disclosure of any Confidential Information provided to any Governmental Authority. The Parties recognize that Duke is required to file periodic reports with FERC that disclose certain price, quantity, and related data, and such
filings shall not be deemed a violation of this section. 
 16.6.3 Survival of Confidentiality Obligations. Confidential Information
received from the other Party shall be kept confidential in accordance with the terms of this Agreement for at least five (5) Years after the termination of this Agreement. 
 16.6.4 Right to Remedies. In the event of an unauthorized disclosure to a third party, the limitations on remedies contained in
Section 16.3.2.1 shall not apply, and, in the event of a breach, Parties shall not have an adequate remedy at law and accordingly shall, in addition to any other available legal or equitable remedies, be entitled to an injunction against such
breach without any requirement to post a bond as a condition of such relief. 
 16.7 Governmental Liabilities. 
 16.7.1 Minimization of Tax Liability. Each Party shall use reasonable efforts to implement the provisions of and to administer this Agreement in
accordance with the intent of the Parties to minimize all taxes, so long as neither Party is materially adversely affected by such efforts. 
 16.7.2 Governmental Charges. 
 16.7.2.1 With respect to sales of electric energy made by Duke to EMC, Duke shall pay or cause
to be paid all Governmental Charges imposed by any Government Authority on or with respect to such sales of electric energy to the extent such Governmental Charges arise prior to the Delivery Point. EMC shall pay or cause to be paid all Governmental
Charges on or with respect to such sale of electric energy to the extent such Governmental Charges arise after the Delivery Point (other than ad valorem, franchise, or income taxes that are related to the sale of such product and are, therefore, the
responsibility of Duke). 
 16.7.2.2 With respect to sales of electric energy by EMC to Duke, EMC shall pay or cause to be paid all
Governmental Charges on or with respect to the sale of the electric energy to Duke. 
 16.7.2.3 In the event a Party is required by
Law to remit or pay Governmental Charges that are the other Party’s responsibility hereunder, the Party ultimately liable for the Governmental Charge shall promptly reimburse the remitting Party for such Governmental Charges; provided further
that tax liabilities may be netted pursuant to Section 13.4 of this Agreement. Nothing will obligate or cause a Party to pay or be liable to pay any Governmental Charges for which it is exempt under the Law. 
 16.7.3 Records. If with respect to either Party, any purchase or sale of electric energy is exempt from Governmental Charges it shall, upon
written request of the other Party, provide a certificate of exemption or other reasonably satisfactory evidence of exemption, and shall use reasonable efforts to obtain and cooperate with obtaining any exemption from or reduction of any
Governmental Charges. 
  

 91 

 16.7.4 Cost of Obtaining FERC Approval. The Parties agree that all fees assessed by FERC, or
expenses incurred in obtaining the approval of FERC for this Agreement, shall be the sole responsibility of Duke. 
 16.7.5 Cost of
Obtaining RUS Approval. The Parties agree that all fees assessed by the RUS, or expenses incurred in obtaining the approval of RUS for this Agreement, shall be the sole responsibility of EMC. 
 16.8 Choice of Law. The validity, interpretation and performance of this Agreement and the rights and duties of the Parties arising out of this Agreement
shall be governed by and construed, enforced, and performed in accordance with the Laws of the State of North Carolina. No principle, doctrine, or rule of conflicts of law shall modify or alter the applicability of the Laws of the State of North
Carolina to this Agreement. 
 16.9 Survival of Obligations. Upon the termination of the Parties’ delivery, sale, purchase, and related service
obligations under this Agreement, any monies, penalties or other charges due and owing under this Agreement shall be paid, any corrections or adjustments to payments previously made shall be determined, and any refunds due shall be made, as soon as
practicable but no later than sixty (60) Days after such termination. All indemnity and confidentiality obligations and audit rights shall survive the termination of this Agreement in accordance with their respective terms. Upon the effective
date of any termination of this Agreement, each Party’s obligations provided for in this Agreement will survive termination and remain in effect solely for the purpose of complying with the provisions of this Section 16.9; OTHERWISE, AS
PROVIDED IN ARTICLE 2, TERMINATION OF THIS AGREEMENT IS ABSOLUTE, AND NO OTHER OBLIGATIONS, DUTIES, OR RIGHTS WHATSOEVER ARISING UNDER THIS AGREEMENT SHALL REMAIN IN EFFECT FOLLOWING THE TERMINATION OF THIS AGREEMENT. 
 16.10 Entire Agreement. This Agreement, and the Schedules and Attachments attached hereto, constitute the entire and integrated agreement between the Parties
relating to the rates, terms, and conditions set out in this Agreement as of the Effective Date. This Agreement supersedes all prior agreements (other than the Confidentiality Agreement which became fully executed on November 22, 2004)
whether oral or written, related to the subject matter of this Agreement. The terms of this Agreement, including any Schedules and Attachments attached hereto, are controlling, and no parol or extrinsic evidence, including but not limited prior
drafts or projections of future costs or rates, shall be used to vary, contradict, or interpret the express rates, terms, and conditions of this Agreement or as a basis for challenging the justness and reasonableness of any rate, term, or condition
of this Agreement. 
 16.11 Cost Projections. 
 16.11.1 Duke Cost Projections. Duke makes no warranties or representations whatsoever concerning any cost or rate projections that it provided in connection with the negotiations leading up to the execution of this Agreement and any
such projections provided by 
  

 92 

 Duke under Section 16.26 of this Agreement. EMC assumes the risk of reliance on any projected costs or rates
provided by Duke in connection with the negotiations leading up to the execution of this Agreement or any projections provided by Duke under Section 16.26. Any differences between projected costs or rates provided by Duke and actual costs or
rates will not limit or in any way affect the rates, terms, or conditions of this Agreement or any of the Parties’ rights and obligations hereunder. 
 16.11.2 EMC Cost Projections. EMC makes no warranties or representations whatsoever concerning any cost or rate projections that it provided in connection with the negotiations leading up to the execution of
this Agreement and any such projections provided by EMC during the Term. Duke assumes the risk of reliance on any projected costs or rates provided by EMC in connection with the negotiations leading up to the execution of this Agreement or any

provided herein, nothing in this Agreement shall be construed to transfer any rights or obligations that either Party has under any other agreement to the other Party. 
 16.14 No Partnership. The Parties are independent contractors. Nothing in this Agreement shall ever be deemed to create or constitute a partnership, joint venture, or association between the Parties, or to
impose a trust or partnership duty, obligation, or liability on or with regard to either of the Parties. 
 16.15 Third Parties. The provisions of
this Agreement shall not impart rights enforceable by any person or entity not a Party or not a permitted successor or assignee of a Party bound by this Agreement. This Agreement shall not be construed to create any third party beneficiary rights of
any sort.

 Schedule 1 
 Annual Production Capacity and Energy Rates 
 Schedule 1 Methodology: 
 This formula sets forth the method that Duke will use to determine its annual Demand Rates, Fuel Rates, and Variable O&M Rates (collectively, “Rates”) for
use during the System Average Pricing Option Period, if any, and during the period January 1, 2011 through the termination of this Agreement. The Rates will be annual formula rate calculations. The Rates shall initially be estimated for the
period January 1 - December 31 of the Year in which such Rates are first applicable, and shall be estimated continuing thereafter for successive twelve month periods. Beginning July 1 of the Year in which such Rates are first applicable,
and each July 1 thereafter, the Rates will be trued-up based on actual costs and loads for the most recent calendar Year, using the formula rates set forth below. The calculations will be based on Duke’s FERC Form 1 data and Duke’s
company records. The true-up will include interest on any refunds or surcharges calculated in accordance with the methodology set forth in 18 C.F.R. § 35.19a or its successor. The formulas for the Rates were designed to include all costs
incurred by Duke to own, operate and maintain Duke’s Generation System. The formulas for the Rates may only be amended by the mutual agreement of the Parties or pursuant to Section 12.3 of the Agreement. Disallowance or any other treatment
of any such costs by the NCUC or any other Governmental Authority other than FERC will not have any effect on the inclusion of such costs in the formulas for the Rates as set forth below.

 II. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During
Light Load Periods (through December 31, 2008) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour
shall be subject to reduction during the period commencing on the Commencement Date and continuing through December 31, 2008 in accordance with the following: 
 A. NCEMC’s contractual right to SO 1996, SOR A and SOR E (654.3 MW rounded to 655 MW) is subject to reduction based on a comparison between 655 MW and NCEMC’s CP&L Native Load (NCNL). 
 B. In the event that NCEMC’s CP&L Native Load during the Hour is less than 655 MW, EMC’s Base Obligation and EMC Group’s Base
Obligation for the Hour shall be reduced as follows: 
 C. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC’s
Base Obligation shall be equal to the amount set forth in Equation 1 below: 
 Equation 1: ( ( 655 MW - NCNL ) / 225 ) * 5 
 D. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC’s Base Obligation shall be equal to 5 MW plus the amount set forth in Equation
2 below: 
 Equation 2: ( ( 430 MW - NCNL ) / 225 ) * 5 
  

 3 

 E. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC Group’s Base
Obligation shall be equal to the amount set forth in Equation 3 below: 
 Equation 3: ( ( 655 MW - NCNL ) / 225 ) * 33 
 F. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC Group’s Base Obligation shall be equal to 33 MW plus the amount set forth in
Equation 4 below: 
 Equation 4: ( ( 430 MW - NCNL ) / 225 ) * 33 
 G. Example: If NCNL is equal to 565 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 655 MW – 565
MW ) / 225 ) * 5 or 2 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( (655 MW - 565 MW) / 225 ) * 33, or 13.2 MW. 
 III. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods (January 1, 2009 through December 31, 2010) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour shall be subject to reduction during the period commencing on
January 1, 2009 and continuing through December 31, 2010 in accordance with the following: 
 A. NCEMC’s contractual right to
SO 1996 and SOR A (429.3 MW rounded to 430 MW) is subject to reduction based on a comparison between 430 MW and NCEMC’s CP&L Native Load (NCNL). 
  

 4 

 B. In the event that NCEMC’s CP&L Native Load during the Hour is less than 430 MW, EMC’s
Base Obligation for the Hour shall be reduced as follows: 
 Equation 5: ( (430 MW - NCNL ) / 225 ) * 5 
 C. In the event that NCEMC’s CP&L Native Load during the Hour is less than 430 MW, EMC Group’s Base Obligation for the Hour shall be
reduced as follows: 
 Equation 6: ( ( 430 MW - NCNL ) / 225 ) * 33 
 D. Example: If NCNL is equal to 340 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340
MW ) / 225 ) * 5 MW, or 2 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340 MW ) / 225 ) * 33, or 13.2 MW. 
 IV. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods for the Catawba Resource Entitlement 
 In addition to the reductions to EMC’s Base Obligation and EMC Group’s Base Obligation set forth under Sections II and III above, EMC’s
Base Obligation and EMC Group’s Base Obligation shall be subject to reduction as set forth in this Section IV. 
  

 5 

 A. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a
nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC’s Base Obligation for the Hour shall be reduced as follows: 
 Equation 7: (1 - ( NDNL / 623.5 MW) ) * 16 MW 
 B. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC Group’s Base Obligation
for the Hour shall be reduced as follows: 
 Equation 8: (1 - ( NDNL / 623.5 MW ) ) * 95 MW 
 C. Example: If NDNL is equal to 561.15 MW during an Hour, and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the
Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( 1 -(561.15 MW / 623.5 MW) ) * 16 MW, which equals ( .1 ) * ( 16 MW ), or 1.6 MW, and the reduction in EMC Group’s
Base Obligation for the Hour shall be equal to ( 1 - (561.15 MW / 623.5 MW ) ) * 95 MW, which equals ( .1 ) * ( 95 MW ), or 9.5 MW.

 Example 1 
 Showing the Calculation of Blue Ridge, Piedmont and 
 Rutherford Allocated Shares of the Duke Total Hourly Energy Charge, 
 EMC Group Total Hourly Energy Credit, Inter-EMC Energy Charge and Inter-EMC Energy Credit 
 The
purpose of this attachment is to provide an example showing the calculation of the charges and credits identified above for one Hour. For purposes of this example, Blue Ridge, Piedmont and Rutherford are referred to individually as BR, P and R,
respectively, and collectively as the EMC Group.

	 Intervals 676-900 - Put Signal during each Interval (kW)
	  	9,000	  	0	  	9,000	  	14,000

	3	Interval numbers refer to the Intervals during the Hour (e.g., Interval 1 is the first four seconds of the Hour, Interval 2 is the next four seconds, etc.). The Call
and Put Signals are shown as the same in each of the first 225 Intervals of the Hour, and then again as the same in the next 225 Intervals and so on. This is a simplifying assumption, to make this example less cumbersome. In actual operation, the
Parties anticipate that these positions would change frequently within the Hour.

 C. Incremental/Decremental Costs 
  

	
	Duke Territorial Incremental Cost: $0.10/kWh
	Duke Territorial Decremental Cost: $0.10/kWh

	4	These numbers sum the four-second Call and Put Signals from Part I.A. For example, 6,000 kW delivered by Duke in each of the 225 four-second Intervals (15 minutes)
equal 1,500 kWh (6,000 KW * 225 Intervals / 900 Intervals / Hour = 1500 kWh).

 ATTACHMENT 7-9 
 Demand Rate Adjustment Percentage and Annual Percentage 
 This attachment provides the formulas to be used for calculating
the Demand Rate Adjustment Percentage and Annual Percentage for each calendar year beginning January 1, 2011. 
 The Demand Rate Adjustment Percentage
shall equal the Production Capacity Revenue Requirement Adjustment divided by the Original Production Capacity Revenue Requirement, but not less than zero. 
 Where 
 Production Capacity Revenue
Requirement Adjustment = (Annual Percentage – 4%) * (Original Production Capacity Revenue Requirement + Original Energy Revenue Requirement) 
 And 
 Annual Percentage shall equal the product of the System Gross Plant Difference and the Fixed Charge Rate,
divided by the sum of Original Production Capacity Revenue Requirement and Original Energy Revenue Requirement. For purposes of calculating the Production Capacity Revenue Requirement Adjustment, the Annual Percentage shall be a maximum of 10%.

 System Gross Plant Difference shall equal EMC Plant in Service less NC Retail Plant in Service. (May be positive or negative.) System Gross Plant
Difference shall be decreased as necessary to eliminate differences between EMC Plant in Service and NC Retail Plant in Service related to timing or method of recovery of plant costs (e.g., plant differences due to recovery of construction period
financing costs through inclusion of construction work in progress in rate base). 
 Fixed Charge Rate shall equal
10%. 
 EMC Plant in Service shall equal the average of the total ending balance of Production Plant, General Plant and Intangible Plant according to
Schedule 1 of this Agreement, for the calendar year for which the Production Capacity Revenue Requirement calculation is prepared and total ending balance of Production Plant, General Plant and Intangible Plant according to Schedule 1 of this
Agreement for the previous calendar year calculation of the Production Capacity Revenue Requirement. 
 NC Retail Plant in Service shall equal the sum
of Duke Power Retail Plant in Service and Nantahala Retail Plant in Service, which shall be determined from Company records supporting the total Electric Plant in Service amount on Schedule 3 of NCUC Form E.S.-1 for the 12 month calendar period
corresponding to the Production Capacity Revenue Requirement calculation used for calculating the EMC Plant in Service. 

 Duke Power Retail Plant in Service shall equal the average of the two December balances for the total of
Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly amounts shown on Schedule 3 of NCUC Form E.S.-1 for Duke Power. 
 Nantahala Retail Plant in Service shall equal the average of the two December balances for the total of Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly
amounts shown on Schedule 3 of NCUC Form E.S.-1 for Nantahala Power & Light. 
 Original Production Capacity Revenue Requirement shall equal
the Production Capacity Revenue Requirement before consideration of any adjustments pursuant to Section 7.3.2.3 of the Agreement. 
 Original Energy
Revenue Requirement shall equal the sum of F for purposes of calculating the Fuel Rate in Schedule 1 and Variable Non-Fuel Production Operation and Maintenance Expense for purposes of calculating the Variable O&M Rate in Schedule 1.

 Attachment 8-1 
 (Part I of II) 
 TERMS AND CONDITIONS 
 FOR THE SCHEDULING OF POWER 
 SUPPLIED BY NORTH CAROLINA 
 ELECTRIC MEMBERSHIP CORPORATION 
 TO
ITS INDEPENDENT MEMBERS 

 All NCEMC Committed Resources associated with the Wholesale Power Supply Agreement between the Seller and
the Buyer are governed by and subject to all of the terms and conditions in this Exhibit, unless a specific Resource Summary Attachment explicitly provides otherwise. Unless defined in this Exhibit, all capitalized terms used herein shall have the
respective meanings set forth as Article One of the Wholesale Power Supply Agreement. 
 General Principles 
  

	1.	Buyer is responsible for planning the way it chooses to use any Capacity or Energy delivered pursuant to one of the Resource Summary Attachments governed by this Exhibit. As a part
of the Wholesale Power Supply Agreement, the Parties have agreed to a set of Resource Summary Attachments that collectively are intended to represent a financial approximation of an allocation of the NCEMC Committed Resources on the Effective Date.

  

	2.	For any hour of delivery, Seller will optimize resources around final dispatch for the combined load of all of Seller’s Participating Members, plus the schedules of the Buyer
and other Independent Members. 

  

	3.	Buyer will pay Seller charges for Energy and the delivery of Energy to the Interface Point under terms specified in Resource Summary Attachments and terms specified elsewhere in
this Agreement including but not limited to Sections 2.4, 2.12 and Article Five. 

 Delivery of Allocated Resources 
  

	4.	Energy Scheduled from Buyer’s Independent Member Allocation is delivered to the Interface Point. The cost and expense of all transmission services, including ancillary services
and losses, from the Interface Point are the sole responsibility of Buyer. 

  

	5.	Seller will be deemed the provider of the resources needed for the purposes of tagging and for the designation of resources under the applicable tariffs of the Transmission
Provider(s) selected by Buyer. 

 Scheduling by Buyer 
  

	6.	All Schedules from Buyer for each Independent Member Allocation will be in whole MWs and may not exceed the IM Allocation MW detailed on the Resource Summary Attachment.

  

	7.	Buyer will submit a separate Schedule in conformance with this Exhibit S by System by resource up to the Maximum Scheduling Limit by System, as further described in Paragraph 23 of
this Exhibit S. 

  

	8.	Buyer will be responsible for scheduling and arranging for the delivery of its SEPA allocation. 

  

 - 2 - 

	9.	For any Independent Member Allocation that is designated as producing Must-Take Energy, Buyer is required to Schedule for every hour of every day of the Delivery Period its full
Must-Take Energy obligation from such a resource, and may not amend or reduce its Schedule for that Energy: provided, however, that to the extent that Seller’s obligation to purchase Must-Take Energy from a resource designated as producing
Must-Take Energy is reduced in any hour, Buyer’s hourly Must-Take Energy obligation shall be adjusted by the ratio of Seller’s hourly Must-Take Energy obligation to the Resource Capacity, rounded to whole MWs. The Buyer shall not be
entitled to Schedule Must-Take Energy in an hour in amounts, which exceed the Buyer’s adjusted Must-Take Energy obligation for that hour. 

  

	10.	Buyer is obligated to Schedule resources in accordance with the terms and conditions provided in the Resource Summary Attachments consistent with the minimum run times in the
contracts pertaining to Seller’s purchased and/or owned resources, and Seller will use its good faith efforts to accommodate Buyer’s Schedules that do not meet the minimum run time requirements, but only so long as meeting such
non-conforming Schedules would not likely result in additional costs to Seller or any of its Participating Members. 

  

	11.	Except with respect to Buyer’s Independent Member Allocations that supply Must-Take Energy, Buyer is not obligated to Schedule its Independent Member Allocations consistent
with the minimum volumes in the power supply contracts of Seller that are in force on the Independent Member Effective Date. 

  

	12.	By 7:00 a.m. EPT each day Buyer must provide Seller with an hourly forecast of its load by System for the following day. 

  

	13.	The Buyer may Schedule its resources consistent with the table below. Day-ahead Schedules are those submitted before 8:00 a.m. EPT the day prior to flow. Intra-day Schedules are
those that are requested after the 8:00 a.m. EPT deadline above. All Schedule changes must occur at the top of the hour. Intra-day Schedule changes require two (2) hours advance notice. 

  

			
	 Scheduling
Changes

	 Day Ahead
	 	 Intra-Day

		
	Unlimited changes up to the IM Allocation MW identified in the Resource Summary Attachment for each resource in whole MWs.	 	Up to two changes to the hourly Schedule for the remainder of the day. Each change to the hourly Schedule shall be no greater than 5%, for a cumulative maximum of 10% each hour. Additional
changes will be accommodated on a best efforts basis.

  

 - 3 - 

 Scheduling by Seller 
  

	14.	Seller is not obligated to meet Buyer’s final Schedule using the NCEMC Committed Resources associated with the Independent Member Allocations Scheduled by Buyer.

  

	15.	Seller will accept the risk and/or benefit resulting from differences in the cost of resources used to provide Buyer Energy in accordance with its Schedule(s), and the costs Seller
would have incurred had it used NCEMC Committed Resources to meet Buyer’s Schedule of the Scheduled resource(s). 

  

	16.	Should Seller acquire an alternate resource, rather than use an NCEMC Committed Resource to serve Buyer’s Schedule, and that alternate resource is curtailed, Buyer’s
Schedule will be maintained and any penalty, benefit or curtailment will be borne by Seller. 

  

	17.	Should all or any portion of NCEMC Committed Resources that have been Scheduled by Seller and Buyer to meet Buyer’s Schedule in any given hour be interrupted, then Seller shall
try to identify available alternate resources which Seller, in its sole discretion, determines are reasonably priced and suitable to meet Seller’s needs. If Seller determines that such alternate resources are available, Seller may maintain the
Scheduled deliveries to Buyer but at a price to be determined by Seller and communicated to Buyer. If no alternate resources are available to Seller, Buyer’s Schedule will be curtailed. All damages recovered by Seller from the Person
responsible for the interruption in service will be shared with Buyer and every other Member similarly affected by such interruption in service. 

 Operations and Planning 
  

	18.	Buyer will provide Seller with a real time telemetered signal of Buyer’s load for Seller’s use, for purposes of determining when to start and stop the dynamic schedule,
and to Schedule certain Must-Take Energy requirements of NCEMC Committed Resources. 

  

	19.	Seller shall provide and inform the Buyer on each Thursday by 1:00 p.m. EPT of the projected amount of Energy available hourly by Independent Member Allocation by System for
Scheduling by Buyer for the following Saturday through Friday period, including the amount of Must-Take Energy that will be delivered and must be taken hourly. 

  

	20.	By 8:00 a.m. EPT each day, Buyer shall provide an hourly forecast of its Native Load by System for the next seven (7) days. For purposes of this Exhibit S, “Native
Load” shall mean only the load of Buyer’s members. This load forecast will be used by Seller to calculate the hourly Energy available from the Independent Member Allocations that are available to be Scheduled for a given interval of time.

  

	21.	Buyer shall provide Seller on each Thursday by 4:00 p.m. EPT, a projected hourly Schedule of all the Independent Member Allocations governed by this Agreement for the following
Saturday through Friday period. 

  

 - 4 - 

	22.	Seller and Buyer agree on the following checkout and verification process: 

 As soon as practical after midnight, confirm hourly Schedules, energy flows and energy charges by resource and daily totals; 
 Provide a contact person each Business Day for the following: 
 Resolve issues that remain unresolved;

 Perform month-to-date confirmations of hourly Schedules, energy flows and energy charges by resource and daily totals; 
 Finalize monthly checkouts by the second Business Day of the following month; and Coordinate any true-ups that may be required. 
  

	23.	For Buyers having loads in more than one System, Buyer will provide at the Independent Member Election Date and on July 1of each subsequent year, a forecast of the percentage
of its retail load in each System. (The sum of the percentages must equal 100%). The Maximum Scheduling Limit by System for the following calendar year will be calculated by multiplying the percentage of Buyer’s retail load in each System times
the total of Buyer’s Independent Member Allocations for the following calendar year.

 Attachment 8-1 
 (Part II of II) 
 TERMS AND CONDITIONS 
 FOR OBTAINING TRANSMISSION 
 SERVICES ADEQUATE TO DELIVER 
 FROM THE INTERFACE POINTS 
 ESTABLISHED UNDER THE 
 WHOLESALE POWER SUPPLY AGREEMENT 
 OF NCEMC FOR SALES TO 
 ITS INDEPENDENT MEMBERS 
  

 - 6 - 

 General Principles and Responsibilities for Transmission: All Resource Summary Attachments associated with
the Wholesale Power Supply Agreement between Seller and Buyer are governed by and subject to the terms and conditions in this Exhibit unless a specific Resource Summary Attachment explicitly provides otherwise. For purposes of this Exhibit, the
Wholesale Power Supply Agreement and each Resource Summary Attachment governed by this Exhibit, the term “Acceptable Transmission Service” means the level of service available at any point in time that is equal to or better than that level
of service currently defined as “Network Integration Transmission Service” under the Open Access Transmission Tariff of the System to which Buyer’s distribution system is physically interconnected, and if connected to more than one
System, then Buyer must have Acceptable Transmission Service for each Interface Point. 
 The following terms for transmission service apply to each Resource
Summary Attachment included as a part of this Agreement. All of these terms assume that the current Open Access Transmission Tariff environment in force on the Effective Date remains in force, without modification or amendment. The Parties hereto
agree that any amendment, modification or change to that tariff or the regulatory environment for the wholesale electric industry, whether by regulation, regulatory action, statute, judicial action, executive decision or order, or otherwise, may
require modification of this Exhibit to restore to Buyer and Seller the benefits that each intended. Such amendments, modifications or changes would include, without limitation, any changes or modifications of the wholesale electric industry
environment based on the Standard Market Design, or the restructuring of the transmission systems or the regulatory oversight of same. If the Parties fail to reach agreement on modifications of this Exhibit, the dispute shall be subject to
arbitration under the Wholesale Power Supply Agreement. 
 Buyer is responsible for planning for and scheduling the receipt of capacity and energy to be
delivered to Buyer. Buyer will be responsible for negotiating, making and keeping in force one or more transmission agreements with the Transmission Provider(s) necessary to perform its obligations under the Wholesale Power Supply Agreement. At a
minimum, Buyer will negotiate, make and keep in force its own Network Integration Service Agreement (“NITSA”) and its own Network Operating Agreement (“NOA”). 
 Subject to and contingent upon the concurrence and agreement of each affected Transmission Provider, the RUS, and the Federal Energy Regulatory Commission (“FERC”), the Parties further agree: 
  

	1.	Buyer is responsible for serving its own load. It will do so through contracts with Seller, along with other resources Buyer will acquire. 

  

	2.	Buyer will have its own transmission agreement(s) with each and any Transmission Provider(s) whose services are needed to move capacity or energy from any Interface Point of the
System(s) to which Buyer’s distribution system is physically interconnected. 

  

	3.	Buyer will negotiate its own NITSA and NOA. Seller will provide assistance with these negotiations as requested. The cost for this assistance will be charged to Buyer separately
from charges for Capacity and Energy billed under Article 5.1 of this Agreement. 

  

 - 7 - 

	4.	Seller will transfer the direct-assigned facilities used for that Buyer, if any, to Buyer’s NITSA once the same has become effective. 

  

	5.	Seller will provide Buyer with contractual rights that financially approximate the hypothetical assignment of a total amount of Seller’s owned and/or purchased resources,
calculated in accordance with the NCEMC Member Power Supply Resource Policy, for purposes of Buyer’s NITSA and NOA designations for energy delivered to the System served by the Transmission Provider with which Buyer has entered its NITSA and
NOA. 

  

	6.	If any need exists or arises to designate, in addition to the contracts with Seller, any other network resources in order to meet Buyer’s load in accordance with the tariffs or
other requirements of the Transmission Provider(s), Buyer has the responsibility to locate, identify and designate such other network resources. 

  

	7.	Buyer will have the obligation to satisfy the requirements of the applicable OATT, and purchase or self-supply, as applicable, any ancillary or other services needed or required to
serve its load. 

  

	8.	Buyer will coordinate with Seller or its scheduling agent under Exhibit S to this Wholesale Power Supply Agreement to assure that the proper schedule is in place each day for
Buyer’s scheduled amount of Energy related to each of Buyer’s Resource Summary Attachments that are governed by this Exhibit. 

  

	9.	In addition to the other responsibilities arising under this Exhibit, Buyer shall be solely liable for any energy imbalance settlement and any other settlements or liabilities to
which a Transmission Customer is exposed at and from the Interface Point(s). If Buyer causes Seller to incur energy imbalance charges, Buyer will reimburse Seller for any charges that Seller incurs.

 (a) During the ninety
(90) Days immediately following the giving of the Notice of Termination, the Parties shall attempt to negotiate amendments to this Agreement that would permit the Parties to restore the equivalent value of the economic 
  

 22 

 bargain contemplated by this Agreement absent the Material Adverse Ruling. If the Parties reach
agreement, such amendments will not become effective unless, within one hundred eighty (180) Days of the date that the Notice of Termination is given, the Parties have obtained the necessary approvals of Governmental Authorities to enable the
amendments to become effective without change, condition or modification. In the event that the Parties fail (i) to reach agreement on such amendments, or (ii) to obtain the necessary approvals of Governmental Authorities, this Agreement
shall terminate on the Material Adverse Ruling Termination Date, subject to the provisions of Section 2.3.2.2(b) and 2.3.2.2.2. 
 (b) In the event that the Parties are unable to reach agreement on the amendments provided in Section 2.3.2.2(a), either Party may, no later than ninety (90) Days after the date that the Notice of Termination is given (or, if
earlier, the date that the Parties mutually agree that they are unable to reach agreement on such amendments), give notice to the other Party of its desire to extend this Agreement for a period of up to twelve (12) Months beyond the Material
Adverse Ruling Termination Date. Such extension will be subject to the Parties (i) having first reached agreement upon the rates, terms and conditions of service for such twelve (12) Month period within one hundred twenty (120) Days
of the date that the Notice of Termination is given and executing such agreement within such one hundred twenty (120) Day period, and (ii) having received from Governmental Authorities the necessary approvals for such rates, terms and
conditions without change, condition or modification within one hundred eighty (180) Days of the date that the Notice of Termination is given. 
 (c) A “Material Adverse Ruling” is an order or action by a Governmental Authority or a change in Law that (i) either (A) modifies the rates, terms, or conditions of this Agreement,
(B) disallows the recovery from EMC of costs that are included in this Agreement, (C) for retail ratemaking or regulatory accounting and reporting purposes, disallows costs related to this Agreement, including any disallowance of
Duke’s costs related to investments in generating facilities or binding contracts to purchase electric capacity and energy to provide service to EMC under this Agreement, or (D) for retail ratemaking or regulatory accounting and reporting
purposes, assigns, allocates or makes pro forma adjustments with respect to the revenues or costs related to this Agreement, and (ii) adversely affects the relative economic position of either Party in a material way. For purposes of this
definition only, 
 (1) “material” for Duke means that the effect of the order or action by the Governmental
Authority or change in Law is reasonably projected to decrease Duke’s net revenues under this Agreement, or, in the case of a disallowance, assignment, allocation, or pro forma adjustment of revenues or costs for retail ratemaking or regulatory
accounting or reporting purposes, either (i) decrease Duke’s net costs or increase Duke’s net revenues assigned or allocated to Duke’s retail customer classes, or (ii) increase Duke’s net costs or decrease Duke’s
net revenues assigned or allocated to Duke’s wholesale customer class, by an aggregate amount equal to five percent (5%) or more of the total revenues to be paid by EMC to Duke under this Agreement over the then-remaining Term; 

 

 23 

 (2) “material” for EMC means that the effect of the order or action by the
Governmental Authority or change in Law is reasonably projected to increase EMC’s net costs under this Agreement by an amount equal to five percent (5%) or more of the total revenues to be paid by EMC to Duke under this Agreement over the
then-remaining Term; 
 (3) an increase in a Party’s net costs is the increase in the Party’s costs as a result of
the order or action by the Governmental Authority or change in Law, less the increase (if any) in the Party’s revenues as a result of the Material Adverse Ruling; and 
 (4) a decrease in a Party’s net revenues is the decrease in the Party’s revenues as a result of the order or action by the
Governmental Authority or change in Law, less the decrease (if any) in the Party’s costs as a result of the Material Adverse Ruling. 
 (d) The foregoing amounts shall be calculated on a nominal rather than an inflation adjusted or present value basis. Without limitation of the foregoing, EMC acknowledges that, for retail ratemaking and regulatory
accounting and reporting purposes, Duke shall calculate the costs of the electric capacity and energy used to serve EMC under this Agreement on a system average cost basis beginning January 1, 2007. EMC agrees that if the amount of costs that
the NCUC or the PSCSC in effect assigns or allocates to, or requires Duke to assign or allocate to, this Agreement for ratemaking or regulatory accounting and reporting purposes exceeds Duke’s system average costs, such action shall constitute
a Material Adverse Ruling if the five percent (5%) materiality standard set forth above is met. 
 2.3.2.2.1 A change in Duke’s
net revenues or EMC’s net costs that results from a change in this Agreement that is permitted under Section 12.3, shall not constitute a Material Adverse Ruling regardless of the impact of such change on either Party’s net costs or
net revenues. 
 2.3.2.2.2 In the event that either Party believes that a Material Adverse Ruling has occurred, the Party affected by such
Material Adverse Ruling shall provide the other Party a good faith calculation together with information supporting the calculation of the projected effect of the Material Adverse Ruling and include such calculation and the cost information
supporting the calculation with the Notice of Termination. If the non-terminating Party notifies the other Party, within twenty (20) Days following the date that such Notice of Termination is given, of its good faith objection to the
calculation or the cost information supporting the calculation of the projected effect of the Material Adverse Ruling, then the Parties shall, within thirty (30) Days following the date that such Notice of Termination is given (the
“Resolution Period”), attempt to resolve their differences with respect to the calculation or the cost information supporting such calculation. If, at the conclusion of the Resolution Period, the Parties are not in agreement with respect
to the calculation or cost information supporting the calculation, then PriceWaterhouseCoopers, or such other nationally recognized accounting firm that is not then the independent auditor for either Party or any of its Affiliates or predecessors
and is selected by mutual agreement of the Parties (the “Neutral Auditors”), shall be engaged 
  

 24 

 within ten (10) Days after the expiration of the Resolution Period to review the calculation and the cost
information supporting the calculation and to make an independent determination as to whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable. If the Neutral Auditors
require any additional information, records, or internal analysis to make a determination as to whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, the Party in
possession of such information, records or internal analysis will provide it to the Neutral Auditors. Each Party agrees to execute, if requested by the Neutral Auditors, a reasonable engagement letter, including customary indemnities. All fees and
expenses relating to the work to be performed by the Neutral Auditors shall be borne one-half (1/2) by the terminating Party and one-half (1/2) by the non-terminating Party. The Neutral Auditors shall act as an arbitrator to determine,
based upon its independent review, whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable. The Neutral Auditors’ determination shall be made within thirty
(30) Days of their selection, shall be set forth in a written statement delivered to both Parties and shall be final, binding and conclusive. If the Neutral Auditors’ determine the materiality standard set forth in
Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met, the Notice of Termination shall be null and void. If the Neutral Auditors’ determine the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is
met, the Notice of Termination shall be effective in accordance with its terms. The initiation of the dispute resolution process described in this Section 2.3.2.2.2, shall not toll or otherwise delay running of the twenty-four (24) Month
time period set forth in the Notice of Termination, unless the Neutral Auditors’ find that the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met. The procedure set forth in this
Section 2.3.2.2.2 shall be the exclusive means for the Parties to resolve any dispute as to whether a Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2). If a Party gives a Notice of
Termination based on its good faith contention of the occurrence of a Material Adverse Ruling that meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, and the Neutral Auditors subsequently determine that
such materiality standard has not been met, such Party shall not be in default under this Agreement solely because it gave such Notice of Termination. 
 2.3.2.3 Early Termination for Failure of Condition Precedent. This Agreement may be terminated for failure of a condition precedent in accordance with Section 3.5.2.2 or Section 3.5.3. 
 2.3.2.4 Early Termination Due to Implementation of Retail Competition. Upon the date of enactment of a Law providing for implementation of retail
electric service competition on a comprehensive basis in the State of North Carolina, the Parties shall enter into negotiations with the goal of reaching agreement on amendments to this Agreement to provide for the continuation of the purchase and

 2.3.2.5 Early Termination Due to Plant Calculation. In the event that the Annual Percentage
calculated in Attachment 7-9 is positive for two (2) consecutive Years, and the absolute value of such percentage is greater than ten percent (10%) then EMC may, within twenty (20) Days after the date in such second
(2nd) consecutive Year that Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4, give Duke Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month that is twenty-four
(24) Months after the Month in which the Notice of Termination is given. In the event that the Annual Percentage calculated in Attachment 7-9 is negative for two (2) consecutive Years, and the absolute value of such percentage is
greater than ten percent (10%) for any two (2) consecutive Years, then Duke may, within twenty (20) Days after the date in such second (2nd) consecutive Year that Duke provides the calculation of the Annual Percentage pursuant to
Section 7.3.2.4, give EMC Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month that is twenty-four (24) Months after the Month in which the Notice of Termination is given. If a Party fails to
give Notice of Termination within twenty (20) Days after Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4 for such second (2nd) consecutive Year, it shall have permanently waived its right to
terminate this Agreement under this Section based on the Annual Percentage for such two (2) consecutive Years; provided, that nothing in this Section 2.3.2.5 shall affect any Party’s termination rights under Sections 2.3.2.1,

 2.3.2.6 Early Termination Due to Extended Force Majeure. If, as a result of an event of Force
Majeure, a Party is unable to meet a material obligation hereunder for a period greater than ninety (90) Days, then the Non-Claiming Party shall have the right to terminate this Agreement upon giving a Notice of Termination within thirty
(30) Days of the expiration of such ninety (90) Day period; provided, however, if the Claiming Party has used and continues to use all Commercially Reasonable Efforts to remedy, cure or mitigate the event of Force Majeure, then the
Non-Claiming Party’s right to give Notice of Termination shall be suspended for so long as the Claiming Party continues to use Commercially Reasonable Efforts to remedy, cure or mitigate the event of Force Majeure. 
 2.3.3 Form of Notice of Termination. Notice of Termination made pursuant to Sections 2.2 or 2.3 shall be given in accordance with
Section 16.22 and shall state (i) the date of termination being effectuated, and (ii) the provision of this Agreement under which termination is being effectuated and the basis for the termination. Except as otherwise provided in this
Section 2.3.3, the Notice of Termination is effective when it is deemed given in accordance with Section 16.22. Once the Notice of Termination is given to a Party, it shall not be deemed amended, modified, or otherwise revoked for any
reason (other than a determination by the Neutral Auditors pursuant to Section 2.3.2.2.2 that the materiality standard is not met) unless such amendment, modification, or revocation is mutually agreed to by both Parties in writing or unless the
Parties reach agreement in accordance with Section 2.3.2.2(a). Upon receipt of the Notice of Termination, the non-terminating Party shall acknowledge receipt in writing sent in accordance with Section 16.22 within five (5) Business
Days of the receipt of the Notice of Termination. Acknowledgment of a Notice of Termination is a courtesy and shall not influence the effectiveness of the termination. Failure to utilize a method specified in Section 16.22 shall not influence
the effectiveness of the termination if the Notice of Termination is actually received by the General Manager of the non-terminating Party within thirty (30) Days of the date 
  

 26

 Article 4 
 Sale of Electric Capacity and Energy 
 4.1 Classification of Services Provided. During the period beginning on the Commencement Date,
and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, Duke shall provide to EMC “FFR Supplemental Service”, as described in Section 4.2. Beginning January 1, 2011, throughout the
remainder of the Term of this Agreement, Duke shall provide to EMC “Partial Requirements Service”, as described in Section 4.3. 
 4.2 FFR
Supplemental Service. 
 4.2.1 Character of FFR Supplemental Service. For each Hour during the period beginning on the Commencement
Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, Duke shall sell and deliver, and EMC shall purchase and receive, all of the electric capacity and energy that EMC requires to serve
EMC’s Native Load in excess of EMC’s Base Obligation for such Hour. For example, if EMC’s Native Load during an Hour is 800 MWs, and EMC’s Base Obligation for such Hour is 600 MWs, Duke shall supply and deliver, and EMC shall
purchase and receive, 200 MWs of FFR Supplemental Service for such Hour. Duke shall supply and deliver FFR Supplemental Service in a manner that is as firm as, and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load.
Duke shall be responsible for maintaining the generation reserves needed to meet its FFR Supplemental Service obligation. Notwithstanding anything in this Agreement to the contrary, Duke shall have no obligation to sell and deliver any electric
capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.2.2 Amount of EMC’s Base Obligation.
EMC’s Base Obligation for each Hour beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall be as set forth in Attachment 4-1. Notwithstanding the
preceding sentence, EMC’s Base Obligation shall be subject to modification (a) during Light Load Periods in accordance with the provisions of Attachment 4-2 or (b) in accordance with the provisions of Section 5.1.4 and

(a) MSCG shall be responsible for scheduling to the Transmission Provider electric energy under the PPA to serve EMC’s Native Load and (b) Duke, acting as Scheduling Agent, shall be responsible for scheduling to the Transmission
Provider, in accordance with the provisions of Article 8, electric energy to serve EMC’s Native Load from EMC’s entitlements to the resources described in Section 5.1.3, 5.1.4 or 5.1.5. The total amount of electric energy so scheduled
to the Transmission Provider in any Hour to serve EMC’s Native Load beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall be the EMC Scheduled Amount;
provided that the EMC Scheduled Amount shall not exceed EMC’s Base Obligation for any such Hour. 
 4.2.4 Scheduling Shortfall.
For each Hour beginning on the Commencement Date, and continuing through December 31, 2010, or any portion thereof in which this Agreement is in effect, if, for any reason, including a Force Majeure as that term is defined herein or a
“force majeure”, “uncontrollable force” or a similar term defined in a third-party agreement, but not including Duke’s unexcused failure to comply with the provisions of Article 8, the EMC Scheduled Amount is less than
EMC’s Base Obligation for any Hour, there shall be a “Scheduling Shortfall” in the amount equal to the difference between EMC’s Base Obligation and the EMC Scheduled Amount in such Hour (“Scheduling Shortfall Amount”).
For any Hour that Duke receives information or a notice pursuant to Section 8.4.8 that there will be or has been a Scheduling Shortfall, Duke shall use Commercially Reasonable Efforts to procure and supply electric energy in a quantity
sufficient to supply the Scheduling Shortfall Amount for such Hour (“Replacement Energy”). In the event that, through the exercise of Commercially Reasonable Efforts, Duke procures Replacement Energy from a third party for resale to EMC,
EMC shall pay Duke for the total cost incurred by Duke to purchase and deliver the Replacement Energy. Duke’s curtailment of a Non-Firm Sale shall constitute a procurement of Replacement Energy from a third party and the total cost incurred by
Duke shall be (i) the foregone sales price for the Non-Firm Sale curtailed and (ii) if applicable, any charges imposed for changes to schedules for the sale of electric energy. In the event that Duke supplies Replacement Energy from its
own resources, EMC shall pay Duke for such Replacement Energy an amount equal to one hundred ten percent (110%) of Duke’s System Incremental Cost in supplying such Replacement Energy. The total charges for Replacement Energy for a Month,
as determined by this Section 4.2.4, shall constitute the Monthly Replacement Energy Charge. 
 4.2.4.1 It is expressly understood that
Section 4.2.4 shall not be construed or interpreted to (i) require Duke to curtail any Firm Sales in order to supply Replacement Energy to EMC, (ii) to curtail any Non-Firm Sales except as set forth in Section 4.2.6 in order to
supply such Replacement Energy to EMC, (iii) impose upon Duke any responsibility for providing Replacement Energy for a Scheduling Shortfall that occurs after the Transmission Provider’s deadline for scheduling transmission service
required for the delivery of such Replacement Energy, or (iv) affect in any way EMC’s rights and obligations under its Network Integration Transmission Service Agreement. 
  

 35 

 4.2.4.2 In the event that there is or is expected to be a Scheduling Shortfall in connection with
(a) EMC or its Scheduling Agent having received notice (and in the event EMC receives notice providing Duke with evidence of such notice) of, or (b) pursuant to Section 8.4.8 Scheduling Agent having received notice of either
(i) the occurrence of a “force majeure” event under the PPA, as defined in Section 4.2.4.3, or (ii) the temporary impairment of generating resources underlying the WPSA, the SEPA Contract, or other resources to which EMC may
have an entitlement pursuant to Section 5.1.3, 5.1.4 or 5.1.5, such that all or a portion of EMC’s entitlements to electric energy under such agreements are or will be temporarily unavailable to EMC, then EMC may request Duke to sell
electric capacity and energy to EMC for the expected duration of such Scheduling Shortfall. In the event that EMC makes such a request, Duke shall exercise Commercially Reasonable Efforts to offer to supply electric capacity and energy to EMC under
rates, terms, and conditions that Duke determines to be commercially reasonable. If the Parties reach agreement on such a sale, then Duke shall sell and deliver and EMC shall purchase and receive the electric energy and such electric energy shall be
included in EMC Scheduled Amount. 
 4.2.4.3 For purposes of Section 4.2.4.2, the term “force majeure” means an event or
circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in part; (ii) is not within the reasonable control of the claiming party, or the result of the negligence of the claiming
party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable manner, and, without limiting the scope of the definition, includes acts of God, or the public enemy, or insurrection,
riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court order or governmental authority or arbitration award (so long as the claiming party has
not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission service interruptions or curtailments imposed by a transmission provider in response to transmission capacity or
availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 4.2.4.3. 
 4.2.5
EMC PPA Obligation. EMC shall retain all of its rights and obligations under the PPA, including the obligation to pay all costs incurred under the PPA. 
 4.2.6 EMC Obligation to Curtail Load. During any Hour in which there is a Scheduling Shortfall, and either (i) Duke does not replace such electric energy in accordance with Section 4.2.4 or
(ii) EMC has not made, or does not have in place, arrangements to replace such electric energy, EMC shall curtail an amount of EMC’s Native Load equal to the Scheduling Shortfall Amount; provided, however, Duke shall exercise Commercially
Reasonable Efforts within the time constraints that exist to first call upon any available EMC Demand Side Management Resource Program that would not otherwise be called upon absent the Scheduling Shortfall and then if necessary curtail Non-Firm
Sales to the extent of the Scheduling Shortfall before requiring EMC to curtail EMC’s Native Load pursuant to this Section 4.2.6. Any such EMC Native Load that has been curtailed shall be restored when the Scheduling Shortfall is no longer
occurring or when the Scheduling Shortfall has been replaced either by electric energy supplied (a) by Duke in accordance with Section 4.2.4 or this Section 4.2.6 or (b) under arrangements made by EMC with third parties.

  

 36 

 4.3 Partial Requirements Service. 
 4.3.1 Character of Partial Requirements Service. For each Hour during the period beginning on January 1, 2011, and continuing through the termination of this Agreement, Duke shall sell and deliver, and EMC
shall purchase and receive, all of the electric capacity and energy that EMC requires to serve EMC’s Native Load in excess of the EMC Contract Resources. Duke shall be responsible for maintaining the generation reserves necessary to meet this
obligation. Duke shall supply Partial Requirements Service in a manner that is as firm as, and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load. Notwithstanding anything in this Agreement to the contrary, Duke
shall have no obligation to sell and deliver any electric capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.3.2 Scheduling of EMC Contract Resources To Serve EMC Native Load. For each Hour beginning on January 1, 2011, and continuing through the Term of this Agreement, EMC’s contractual entitlement to electric energy from the
Dispatched Combined Cycle Resources and from the Baseload Resources shall be scheduled in accordance with the provisions of Sections 4.3.3 and 4.3.4, respectively. 
 4.3.3 Scheduling of the Combined Cycle Resources. Duke may schedule, in accordance with Attachment 4-3 and Article 8, each of the Combined Cycle Resources pursuant to Duke’s economic dispatch as
necessary to serve Duke’s total electric energy obligations. Duke shall make no adverse distinction against the Combined Cycle Resources in determining the dispatch order of Duke’s Generation System and the Combined Cycle Resources. The
Combined Cycle Resources that Duke schedules pursuant to economic dispatch shall be referred to as the “Dispatched Combined Cycle Resources”. Except as provided in Section 4.3.3.1 and Section 4.3.3.2, EMC shall be solely
responsible for all costs associated with the Combined Cycle Resources. 
 4.3.3.1 Duke shall not be obligated to pay for any costs that EMC
incurs as a result of Duke’s dispatch of the Combined Cycle Resources to the extent that Duke’s dispatch of such Combined Cycle Resources is for the purpose of serving Duke’s Native Load and, during any Year, Duke’s dispatch of a
Combined Cycle Resource for that purpose does not exceed an Annual Capacity Factor of twenty percent (20%). In the event and at such time during a Year that Duke’s dispatch of a Combined Cycle Resource to serve Duke’s Native Load exceeds
an Annual Capacity Factor of twenty percent (20%), Duke shall pay EMC, in the manner and time provided for in Article 13, the additional Energy Cost that EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource for the
remainder of the Year. For example, if a Dispatched Combined Cycle Resource has a generating capacity of one hundred (100) MWs during a Year and, as of 11:59:59 p.m. on November 30 of such Year, Duke has dispatched such resource for
175,200 MWhs for the purpose of serving Duke’s Native Load, Duke shall reimburse EMC for the Energy Costs that EMC incurs in December of such Year as a result of Duke’s dispatch of such Dispatched Combined Cycle Resource. For the purpose
of this Section 4.3.3.1, “Annual Capacity Factor” means the total amount of electric energy generated by a Dispatched Combined Cycle Resource for the purpose of serving Duke’s Native Load during a Year divided by the product of
(a) the total generating capacity of such Dispatched Combined Cycle Resource and (b) 8,784 (during a leap year) or 8,760 (during a Year other than a leap year), multiplied by one hundred percent (100%). 
  

 37 

 4.3.3.2 In the event that Duke’s dispatch of one or more of the Combined Cycle Resources is for any
purpose other than to serve Duke’s Native Load, Duke shall pay EMC, in the manner and time provided for in Article 13, the additional Energy Cost that EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource(s).

 4.3.3.3 For purposes of Sections 4.3.3.1 and 4.3.3.2, “Energy Cost” means, with respect to any Dispatched Combined Cycle
Resource, all variable costs incurred by EMC that are associated with the production of electric energy under the WPSA, including the cost of fuel, start charges, and any other variable charges incurred by EMC under the WPSA in connection with the
electric energy dispatched by Duke from such Combined Cycle Resource regardless of NCEMC’s actual generating cost or NCEMC’s contractual source of the electric energy. 
 4.3.4 Scheduling of Baseload Resources. Duke shall schedule, in accordance with Article 8, all of the Baseload Resources to the full extent
that EMC’s entitlement to such resources are available to EMC and such electric energy shall be used to serve EMC’s Native Load. EMC shall be solely responsible for all costs associated with the Baseload Resources. The Baseload Resources
that Duke schedules pursuant to this Section 4.3.4 shall be referred to as “Dispatched Baseload Resources”. 
 4.4 Excepted Load.
Notwithstanding anything to the contrary herein, Duke shall have no obligation to supply electric capacity or energy required by EMC to serve Excepted Load. Excepted Load shall consist of EMC load that is either (a) Non-Conforming Load or
(b) Non-Duke Control Area Load. Non-Conforming Load shall consist of (i) EMC load resulting from the merger of EMC with another electric membership corporation or other entity (except to the extent such load was, at the time of the merger,
already being served by Duke under an agreement substantially similar to this Agreement), and (ii) EMC wholesale load. Non-Conforming Load shall also consist of discrete EMC load (a) to which electric service from EMC shall have commenced
after the Effective Date, (b) that has a projected peak demand in excess of twenty-five (25) MW for the Year in which electric service from the EMC commences, and (c) which is projected to change within a one-minute period by a
significant quantity on a recurring basis due to the nature of the retail customer’s operations (e.g., without limitation, an arc furnace). 
 4.5 Good Title. Electric energy that is delivered by Duke to EMC shall be free and clear of all liens, Claims, and encumbrances at the Delivery Points, where title to electric energy provided by Duke hereunder shall transfer to EMC.
Electric energy that is delivered by EMC to Duke shall be free and clear of all liens, Claims, and encumbrances at the point where title to the electric energy is transferred to Duke. 
 4.6 Power Quality. All electric energy provided hereunder at the point of delivery shall be three (3) phase, sixty (60) hertz, and at system nominal voltages.

 Article 5 
 EMC Resources 
 5.1 EMC Contract Resources (Commencement Date - December 31, 2010). 
 5.1.1 Identification of Resources. Except as provided in Section 5.4.1, EMC’s Contract Resources during the period commencing on the
Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall consist of EMC’s entitlement to electric capacity and energy under the PPA and such additional generation or
purchased power resources or entitlements as EMC may acquire pursuant to Sections 5.1.3, 5.1.4 and 5.1.5. The FFR Resource is listed in Attachment 4-1. Except as provided in this Section 5.1.1, EMC shall not, without first
obtaining Duke’s prior written consent, enter into any other contracts for, or acquire any ownership interest in or contractual entitlement to, any additional electric generating resources or electric capacity or energy under which electric
capacity and energy would be used to serve EMC’s Native Load during the Term. 
 5.1.2 Changes to FFR Resources. During the
period commencing on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, EMC shall not: (a) take any action that would materially affect the quantity or quality of
MSCG’s service obligations under the PPA without first obtaining Duke’s prior written consent, or (b) agree to any modification to provisions of the PPA, the WPSA, or the SEPA Contract that would increase or decrease EMC’s
entitlement to electric capacity or energy under such agreements and for which EMC’s consent is required (except as provided in Section 5.1.4) without first obtaining Duke’s consent to such modification. 
 5.1.3 Resource Impairment. In the event that all or a portion of the FFR Resource, or any other EMC Contract Resource, is terminated or becomes
permanently impaired, EMC shall acquire, at EMC’s expense, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent size and comparable
reliability to the EMC Contract Resource, or portion thereof, that such substitute is replacing. 
 5.1.4 New Catawba Resource. In the
event that NCEMC acquires all or part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with such entitlement being made
available throughout the Year to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the entitlement so acquired by EMC. Upon Duke’s request,
EMC shall provide evidence reasonably satisfactory to Duke demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric system generating reserves. Duke shall limit such requests to one
(1) request per Year; provided, that if Duke reasonably believes that the sufficiency or reliability of the electric system generating reserves backing EMC’s entitlement in the Catawba Nuclear Station may have changed since Duke’s
last such request, this limitation shall not apply. In the event that EMC fails to demonstrate that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase,
such reserves in an amount equal to that required under Duke’s Generation 
  

 39 

 Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as
determined under the prior sentence) supplied by Duke to EMC at the then-applicable Monthly Demand Charge. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of EMC’s Base Obligation. This Monthly
charge shall be billed by Duke in accordance with the provisions of Article 13. 
 5.1.4.1 In the event that NCEMC purchases electric
capacity and energy from Duke in lieu of NCEMC’s acquisition of all or a part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station as provided in Section 5.1.4, and NCEMC sells, allocates
or transfers a portion of such electric capacity and energy to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the electric capacity and energy
so acquired by EMC. 
 5.1.5 Non-Consent Modification of EMC’s Contract Resources. In the event that EMC’s entitlements to
electric capacity and energy are reduced in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3 and 2.4 of the SEPA Contract, the amount of the EMC’s Base Obligation shall not be affected and the
provisions of Section 4.2.4.2 shall apply, except that if the Parties are unable to reach agreement as to the rates, terms and conditions under which Duke would sell electric capacity and energy to EMC, the provisions of Section 5.1.3
shall apply. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of any modificaton to EMC’s entitlement to electric capacity and energy under the WPSA or SEPA Contract pursuant to this
Section 5.1.5. In the event that EMC’s entitlements to electric capacity and energy are increased in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3, 2.4 and 2.8 of the SEPA Contract, then,
prior to the effective date of such increase, EMC may elect either to (a) increase EMC’s Base Obligation by the same amount and to the same extent as EMC’s entitlements to electric capacity and energy are increased, or (b) make
arrangements for the sale of EMC’s entitlements to such electric capacity and energy to a third party or to Duke. If EMC fails to complete the arrangements described in (b) of the preceding sentence by the effective date of the increase in
entitlements, then, as of the effective date of the increase in entitlements, the EMC’s Base Obligation automatically will be increased as described in (a) of the preceding sentence. 
 5.2 EMC Contract Resources (January 1, 2011 - Termination of Agreement). 
 5.2.1 Identification of Contract Resources. Except as provided in Section 5.4.1, EMC’s Contract Resources during the period January 1, 2011, through the termination of this Agreement shall
consist of EMC’s entitlements to electric capacity and energy under the contracts listed in Attachment 4-3 and such additional generation or purchased power resources or entitlements as EMC may acquire pursuant to Sections 5.2.3,
5.2.4, and 5.2.5. EMC’s entitlements under the contracts that are listed in Attachment 4-3 shall be referred to as the Partial Requirements Resources. Partial Requirements Resources consist of two (2) categories of entitlements:
Baseload Resources and Combined Cycle Resources. The amount and the material cost and operational terms and conditions of the Baseload Resources and Combined Cycle Resources shall be as set forth in Attachment 4-3, subject to modification in
accordance with Sections 5.2.3 and 5.2.4. Except as provided in this Section 5.2.1, EMC shall not, without first obtaining Duke’s prior written consent, enter into any other contracts for, or acquire any ownership interest 

 

 40 

 in or contractual entitlement to, any additional electric generating resources or electric capacity or energy under which
electric capacity and energy would be used to serve EMC’s Native Load during the Term. 
 5.2.1.1 Extension of WPSA and SEPA
Contract. Consistent with the provisions of Section 5.2.2, EMC shall have the right, without the prior consent of Duke, to extend the term of the WPSA or the SEPA Contract under substantially the same terms and conditions as exist at the
time that EMC seeks to extend the term of the WPSA or the SEPA Contract. If EMC extends the term of the WPSA or the SEPA Contract in accordance with this Section 5.2.1.1, the EMC Contract Resources listed in Attachment 4-3 shall be
deemed to be changed accordingly. 
 5.2.2 Changes To Partial Requirements Resources. Commencing January 1, 2011, through the
termination of this Agreement, EMC shall not (a) take any action that would materially affect the quantity or quality of EMC’s entitlement to electric capacity and energy from the Partial Requirements Resources without first obtaining
Duke’s prior written consent, or (b) agree to any modification to provisions of the WPSA or the SEPA Contract that would increase or decrease EMC’s entitlement to electric capacity or energy under such agreements and for which
EMC’s consent is required (except as provided in Section 5.2.4) without first obtaining Duke’s consent to such modification. 
 5.2.2.1 Modifications Effective After Termination. Notwithstanding the provisions of Section 5.2.2, EMC shall be permitted to agree to any resource modification under the WPSA or the SEPA Contract without obtaining Duke’s
consent to the extent that such resource modification will become effective after the Term; provided, that if such resource modification will become effective prior to the end of the Term, EMC’s Partial Requirements Resources and Duke’s
obligation to provide Partial Requirements Service shall not be modified prior to the date that this Agreement is terminated unless Duke consents to such modification. 
 5.2.2.2 Sufficiency of Reserves. Upon Duke’s request, EMC shall provide evidence reasonably satisfactory to Duke demonstrating that each of EMC’s Partial Requirements Resources is backed by sufficient
and reliable electric system generating reserves. Duke shall limit such requests to one (1) request per Year with respect to any Partial Requirements Resource; provided, that if Duke reasonably believes that the sufficiency or reliability of
the electric system reserves backing any Partial Requirements Resource may have changed since Duke’s last such request, this limitation shall not apply with respect to that Partial Requirements Resource. In the event that EMC fails to
demonstrate that its entitlement in a Partial Requirements Resource is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s Generation
Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined under the prior sentence) supplied by Duke to EMC and the then applicable Monthly Demand Charge. This Monthly charge
shall be billed by Duke in accordance with the provisions of Article 13. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of the amount of Partial Requirements Resources, Baseload Resources or
Combined Cycle Resources. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of a material change to the seller’s service obligations under the contracts listed in Attachment 4-3; provided,
that such notice shall be for information purposes only, and shall not affect any other obligations of either Party under this Agreement. 
  

 41 

 5.2.3 Non-Consent Partial Requirements Resource Modifications. In the event that EMC’s
entitlements are modified pursuant to Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3, 2.4 and 2.8 of the SEPA Contract, EMC’s Partial Requirements Resources shall be modified in the same amount and to the same
extent. To the extent that a Partial Requirements Resource is modified pursuant to this Section 5.2.3, and the modification changes EMC’s entitlement in a resource listed as a Baseload Resource in Attachment 4-3, the amount of such
Baseload Resource, as listed in Attachment 4-3, shall be deemed to be changed accordingly. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of any modification to EMC’s entitlement to
electric capacity and energy under the WPSA or SEPA Contract pursuant to this Section 5.2.3. To the extent that a Partial Requirements Resource is modified pursuant to this Section 5.2.3, and the modification changes EMC’s entitlement
in a resource listed as a Combined Cycle Resource in Attachment 4-3, the amount of such Combined Cycle Resource, as listed in Attachment 4-3, shall be deemed to be changed accordingly. 
 5.2.4 New Catawba Resource. In the event that NCEMC acquires all or part of Saluda River Electric Cooperative’s existing ownership interest
in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with such entitlement being made available throughout the Year to EMC (through modification of the WPSA or pursuant to a new contract), the
entitlement or resource so acquired by EMC shall constitute an additional Partial Requirements Resource, and shall be deemed to be an additional Baseload Resource. Upon Duke’s request, EMC shall provide evidence reasonably satisfactory to Duke
demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric system generating reserves. Duke shall limit such requests to one (1) request per year; provided, that if Duke reasonably believes
that the sufficiency or reliability of the electric system generating reserves backing EMC’s entitlement in the Catawba Nuclear Station may have changed since Duke’s last such request, this limitation shall not apply. In the event that EMC
fails to demonstrate that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s
Generation Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined under the prior sentence) supplied by Duke to EMC and the then-applicable Monthly Demand Charge. This Monthly
charge shall be billed by Duke in accordance with the provisions of Article 13. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of the amount of Partial Requirements Resources, Baseload
Resources or Combined Cycle Resources. 
 5.2.4.1 In the event that NCEMC purchases electric capacity and energy from Duke in lieu of
NCEMC’s acquisition of all or a part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station as provided in Section 5.2.4, and NCEMC sells, allocates or transfers a portion of such capacity
and energy to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Baseload Resources shall be increased by an amount equal to the amount of the electric capacity and energy so acquired by EMC. 
  

 42 

 5.2.5 Resource Impairment. In the event that all or a portion of an EMC Contract Resource is
terminated or becomes permanently impaired, EMC shall acquire, at EMC’s cost, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent
size and comparable reliability to the EMC Contract Resource, or portion thereof, that such substitute resource is replacing, and that Duke reasonably agrees is sufficiently reliable. EMC’s acquisition of such substitute resource shall not
affect the determination of the amount of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. 
 5.3 No Duke Obligation for
Customer Resources. Unless otherwise explicitly provided in this Agreement, nothing herein shall be interpreted or construed as imposing upon Duke any obligations or liabilities, or for transferring to Duke any EMC obligations or liabilities,
under or otherwise pertaining to any EMC Contract Resource, nor shall anything in this Agreement be interpreted or construed as creating or implying any contractual or other relationship between Duke and any other party as to a EMC Contract
Resource. 
 5.4 New Customer Resources. Except as provided in Section 5.4.1, Duke shall have no obligation to amend this Agreement and EMC shall
not make an application to FERC requesting that FERC require that any amendment be made to this Agreement, to accommodate any contractual entitlement to and/or ownership interest in or pertaining to any new electric capacity and/or energy resource
that EMC may obtain after the Effective Date. 
 5.4.1 PURPA Resources. Nothing herein shall limit EMC’s right to purchase
electric capacity and energy from a Qualifying Facility or other renewable resources pursuant to PURPA (“PURPA Resource”). If, during the Term, EMC purchases electric capacity and energy from a PURPA Resource with a nameplate capacity
equal to or greater than one (1) MW, then, for each Month during the period of such purchase: (i) the average hourly integrated electric energy delivered to EMC by such PURPA Resource during the Hours used for determination of the EMC
Monthly Demand Quantity determined in accordance with Section 7.1.4.1 or used for determination of the Monthly Billing Demand determined in accordance with Section 7.2.2.2 or Section 7.3.2.2, increased for losses between the point of
measurement of EMC’s Native Load and the Duke generation level, shall be added to the EMC Monthly Demand Quantity determined in accordance with Section 7.1.4.1 or to the Monthly Billing Demand determined in accordance with
Section 7.2.2.2 or Section 7.3.2.2 for such Month, as applicable; (ii) for purposes of calculating the electric energy charges under Sections 7.1.5, 7.2.3 and 7.3.3, as applicable, the amount of electric energy provided to EMC by such
PURPA Resource during an Hour, increased for losses between the point of measurement of EMC’s Native Load and the Duke generation level, shall be added to EMC’s Native Load and to the EMC Group Native Load for such Hour; and
(iii) Duke shall credit EMC, on a Monthly basis, an amount equal to the electric capacity and energy credits to which EMC would be entitled as set forth in Duke’s NCUC retail electric tariff Schedule PP-H or Schedule PP-N (as applicable),
Interconnected to Distribution System or Transmission System (as applicable), or its successor tariff, if the electric capacity and electric energy provided to EMC by such PURPA Resource were provided to Duke pursuant to and in accordance with such
schedules. The interconnection to Duke’s (rather than the EMC’s) Distribution System or Transmission System, as those terms are defined in the schedules, will determine whether the Distribution System or Transmission System rates apply.
EMC will coordinate with Duke to determine the proper application of these schedules. If Schedule PP-H 
  

 43 

 or Schedule PP-N do not apply to the PURPA Resource, then Duke shall credit EMC, on a Monthly basis, an amount equal to
the electric capacity and energy credits to which EMC would be entitled under PURPA if the electric capacity and electric energy provided to EMC by such PURPA Resource were provided to Duke pursuant to PURPA. EMC’s purchase of the electric
capacity and energy from a PURPA Resource shall not affect the determination of the Annual Capacity Quantity determined in accordance with Sections 3.5.2.3.1, 3.5.2.3.2 or 3.5.2.3.3, as applicable. 
 Article 6 
 Priority of Service

 6.1 Interruption of FFR Supplemental Service and Partial Requirements Service. FFR Supplemental Service and Partial Requirements Service shall
have an interruption priority equivalent to Duke’s Native Load. It is expressly understood and agreed that, except for Duke’s failure to comply with Section 6.2 or as provided in Section 6.4, Duke shall not be liable to EMC for
damages resulting from any such interruptions or impairment of FFR Supplemental Service or Partial Requirements Service. Duke shall use Commercially Reasonable Efforts to notify EMC by telephone of any scheduled interruption or scheduled impairment
of service hereunder and shall use Commercially Reasonable Efforts to confirm such notice by facsimile, electronic mail, or letter on the same date such notice was given. Duke shall notify EMC by telephone of any unscheduled interruption or
impairment of service hereunder as soon as reasonably practicable under the circumstances resulting in such unscheduled interruption or impairment of service. Duke shall use Commercially Reasonable Efforts to remove all causes of such interrupted or
impaired service hereunder. 
 6.2 Curtailments of Load. Except as provided in Section 4.2.6, EMC’s Native Load shall be subject to
curtailment only in accordance with this Section 6.2. In the event that Duke curtails Duke Native Load for any reason, including Force Majeure, EMC shall curtail its load as directed by Duke. Except as provided in Section 4.2.6, Duke shall
not adversely distinguish against EMC’s Native Load in curtailing Duke’s Native Load and directing EMC to curtail EMC’s Native Load; provided, however, that Duke has sole responsibility to design all curtailments, and may order any
manner of curtailment that Duke believes is appropriate so long as EMC’s Native Load and Duke’s Native Load present in the electrical area being curtailed are curtailed on a non-discriminatory basis. In permitting EMC to restore EMC’s
Native Load and restoring Duke’s Native Load that was curtailed, Duke shall not adversely distinguish against EMC’s Native Load, except as provided in Section 4.2.6. The load curtailment and restoration provisions set forth in this
Section 6.2 are in addition to, and without limitation of, the load curtailment and restoration provisions set forth in Section 4.2.6. 
 6.3
Emergency Load Curtailment Program. EMC agrees to implement an emergency load curtailment program for the curtailment of EMC’s Native Load in the event a load curtailment order is made by Duke. EMC shall comply with its obligation to
implement and maintain an emergency load curtailment program and to curtail EMC’s Native Load in the manner specified by Section 6.2. 
  

 44 

 6.4 Substitute Energy. In the event that Duke fails to deliver a sufficient quantity of electric energy to meet
its obligations to provide FFR Supplemental Service or Partial Requirements Service, as the case may be, and Duke’s failure to deliver such electric energy is not pursuant to a curtailment permitted under Section 4.2.6 or 6.2 of this
Agreement, or is otherwise excused under this Agreement, Duke shall pay to EMC an amount equal to EMC’s Cover Costs, if any, incurred for the electric energy that EMC obtained to replace such electric energy (“Substitute Energy”) Duke
failed to supply. EMC’s Cover Costs shall be equal to Substitute Energy Costs incurred by EMC for the Substitute Energy minus the costs that EMC would have incurred had Duke supplied the electric energy to EMC. EMC shall bill its Cover Costs to
Duke in accordance with the provisions of Article 13. In the event that EMC incurs Cover Costs for Substitute Energy over a period that extends past the Month in which Duke’s failure to deliver electric energy occurs, then Duke shall pay
the Cover Costs incurred in the following Month(s) in accordance with the billing and payment provisions of Article 13. 
 6.5 Substitute Energy
Costs. Substitute Energy Costs shall be equal to (i) in the case in which EMC contracts with an energy supplier to provide Substitute Energy to EMC, the cost that EMC, acting in a commercially reasonable manner, incurs to purchase such

 7.4.1 Force Majeure Events. Notwithstanding the provisions of Section 7.4, in the event that Duke provides Replacement Energy to EMC due to
the occurrence of a force majeure event, EMC shall not incur a Monthly Reserve Capacity Charge due to Duke’s provision of Replacement Energy for the first twenty-four (24) Hours following such occurrence. For purposes of this
Section 7.4.1, the term “force majeure” means an event or circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in part; (ii) is not within the reasonable control
of the claiming party, or the result of the negligence of the claiming party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable manner, and, without limiting the scope of the
definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court order or
governmental authority or arbitration award (so long as the claiming party has not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission service interruptions or curtailments
imposed by a transmission provider in response to transmission capacity or availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 7.4.1. 
 7.5 Payment. All charges or payments contemplated by this Article 7 shall be made in accordance with provisions of Article 13. 
 7.6 Determination of EMC Capacity and Energy Demands. For purposes of determining the electric capacity and energy charges under this Agreement, EMC’s Native
Load demands shall be as determined under the NOA (which demands shall include the adjustments under the NOA for losses between the point of delivery under the NITSA and the point of measurement, and the corrections under the NOA for any metering
failures or inaccuracies), and shall be increased by (1 / (1 - TLF ), in order to reflect such demands at the generation level (i.e., at the point at which power is available for transmission). Metered receipts used in billings and accounting
hereunder will in all cases include adjustments for such losses. TLF shall be equal to the transmission loss factor set forth in the Transmission Provider’s OATT, and shall be expressed as a decimal. For example, if the transmission loss factor
in the Transmission Provider’s OATT is three percent (3%), then ( 1 / (1 - TLF )) shall be equal to ( 1 / (1 -.03)), or ( 1 / .97 ). In the event that the NOA is terminated, or the electric capacity and energy demands measured under the NOA no
longer include an adjustment for losses between the point of delivery under the NITSA and the point of measurement or provisions for correcting such demands for metering failures or inaccuracies, then, for purposes of determining the capacity and
energy charges under this Agreement, EMC’s metered electric capacity and energy demands shall be adjusted for losses between the point of delivery under the NITSA and point of measurement and further increased by ( 1 / (1-TLF)), in order
to reflect such demands at the generation level (i.e., at the point at which power is available for transmission), and suitable arrangements shall be made by the Parties for correcting such demands due to metering failures or inaccuracies.

 58 

 9.3.1 Energy Imbalance Responsibility. Duke shall reimburse EMC in accordance with the provisions
of Article 13 for any Hour in which, as a result of Duke’s unexcused failure to comply with the provisions of Article 8, Energy Imbalance Service charges are incurred by EMC in accordance with the Transmission Provider’s OATT. EMC shall
reimburse Duke in accordance with the provisions of Article 13 for any Hour in which, as a result of Duke’s unexcused failure to comply with the provisions of Article 8, Energy Imbalance Service compensation is provided to EMC in accordance
with the Transmission Provider’s OATT. 
 9.4 Regional Transmission Organization. If an ISO, RTO, ITC or other future organization, agency or
authority that has been approved by FERC to serve as the Transmission Provider, then Duke and EMC will reasonably cooperate to make or enter into arrangements with such entity to assist such entity with the implementation of this Agreement. It is
expressly understood that neither the implementation of an ISO, RTO, ITC or other future organization, agency or authority that has been approved by FERC to serve as the Transmission Provider nor the failure of the Parties to enter into the
arrangements contemplated under this Section 9.4 shall relieve either Party of any obligations under this Agreement. 
 9.4.1 Cost
Responsibility. Except as provided in Section 9.3.1, it is expressly understood that nothing herein shall be construed to in any way relieve EMC of, or impose upon Duke, the responsibility for any fees, costs, or charges (including but not
limited to congestion costs, transmission losses, or the costs or charges to secure financial transmission rights or the equivalent thereof) that may be imposed on EMC by an ISO, RTO, ITC or other future organization, agency or authority that has
been approved by FERC to serve as the Transmission Provider in connection with the provision of Transmission Service or Ancillary Services. It is further expressly understood that Duke shall have no right or interest in any financial transmission
rights or the equivalent thereof that are allocated, assigned, transferred or acquired by EMC. 
 9.4.2 Congestion Costs. In the event
that the Transmission Provider implements a pricing methodology that allocates congestion costs on a locational basis, in determining the dispatch order of Duke’s Generation System, Duke shall make no adverse distinction between Duke’s
Native Load and Duke’s obligations to supply FFR Supplemental Service or Partial Requirements Service, as applicable under this Agreement. Duke further agrees that, in the event it designates Delivery Points for Duke’s Generation System,
Duke shall make no adverse distinction between Duke’s Native Load and Duke’s obligations to supply FFR Supplemental Service or Partial Requirements Service, as applicable under this Agreement. The Parties shall reasonably cooperate with
each other in an effort to develop and implement congestion management strategies designed to minimize the incurrence of congestions costs associated with the delivery of electric energy under this Agreement. Duke will provide EMC with recommended
strategies to manage such congestion costs, under terms that would not subject Duke’s Native Load to any costs that Duke would not otherwise incur, and if EMC agrees with such recommendation, Duke will use Commercially Reasonable Efforts to
implement the recommended congestion management strategies. Duke shall also use Commercially Reasonable Efforts to comply with the congestion management rules that may be adopted by the Transmission Provider. 
  

 59 

 Article 10 
 Operating Committee 
 10.1 Operating Committee. The Parties shall establish an Operating Committee consisting
of one (1) Representative each. The Operating Committee shall act only by unanimous agreement or consent. Duke and EMC shall designate their respective Representatives to the Operating Committee, plus any alternate, by written notice delivered
in accordance with Section 16.22 within thirty (30) Days after the Effective Date. Each Party’s Representative on the Operating Committee is authorized to act on behalf of such Party with respect to any matter arising under this
Agreement. 
 10.2 Duties of the Operating Committee. The Operating Committee shall facilitate the coordination and interaction between the Parties
with respect to the performance of the duties and obligations imposed on the Parties hereunder, including development or revision of appropriate protocols and procedures therefor. The Operating Committee shall not, however, have any authority to

 Article 11 
 Demand Side Management 
 11.1 Availability of Demand
Side Management Resource Programs. EMC may make available to EMC’s Native Load customers EMC Demand Side Management Resource Programs to the same extent and under comparable terms and conditions as Duke’s Demand Side Management
Resource Programs; provided, however, that EMC may not make available to EMC’s Native Load customers any demand side management resource programs or similar programs other than such EMC Demand Side Management Resource Programs unless EMC is
otherwise required by RUS or by applicable Law to make other demand management side resource programs available to EMC’s Native Load customers or is otherwise permitted under Section 11.7. Except as set forth in Section 4.2.6, the
terms and conditions of EMC Demand Side Management Resource Programs shall be applied to EMC’s Native Load customers and enforced by Duke in the same or comparable manner as they are applied to Duke’s Native Load retail customers and
enforced by Duke. Except as set forth in Section 4.2.6, in implementing and operating such EMC Demand Side Management Resource Programs, Duke shall make no adverse distinction with respect to EMC’s Native Load. 
 11.2 Changes to Demand Side Management Resource Programs. Upon ninety (90) Days prior written notice, Duke shall advise EMC of any modifications, additions,
or deletions that have been or will be made to the Demand Side Management Resource Programs, and the EMC Demand Side Management Resource Programs available hereunder to EMC’s Native Load customers shall be deemed to have been revised to reflect
such modifications, additions, or deletions without any further action required by either Party. 
  

 60 

 11.3 Credits. Except for any EMC Demand Side Management Resource Program implemented pursuant to Section 11.7
of this Agreement, for each EMC Native Load customer that implements an EMC Demand Side Management Resource Program, EMC shall be entitled to a billing credit. Such billing credit shall be calculated in accordance with the credit applicable for the
Demand Side Management Resource Program, as specified in the rider approved and on file with NCUC for such Demand Side Management Resource Program. Each Month, Duke shall aggregate the total billing credits to which EMC is entitled pursuant to this
Section 11.3, and provide EMC a credit on the Monthly statement delivered in accordance with Section 13.2 equal to the total billing credits for such Month. 
 11.4 Necessary Arrangements. To the extent that an EMC Native Load customer agrees to implement an EMC Demand Side Management Resource Program, the Parties shall cooperate in preparing any detailed
implementation procedures and arrangements required to implement such program, provided that, except for any EMC Demand Side Management Resource Program implemented pursuant to Section 11.7 of this Agreement, Duke shall retain sole operational
control over such EMC Demand Side Management Resource Program implemented. The failure of the Parties to agree on detailed implementation procedures and obligations shall not affect Duke’s obligation to provide EMC with credits as determined by
Section 11.3. 
 11.4.1 Audits. For each EMC Demand Side Management Resource Program whose credit depends upon the number of EMC
Native Load customers, EMC shall be required to provide Duke written notice, by no later than January 31 of each Year, of the number of EMC Native Load customers with whom EMC has entered into arrangements pursuant to this Section 11.4 for
such EMC Demand Side Management Resource Program. Duke shall have the right periodically to perform audits, in accordance with the terms of Section 13.6, to verify the accuracy of the notices concerning the number of EMC Native Load customers
with whom EMC has entered into arrangements for each EMC Demand Side Management Resource Program. Based on the results of such audits, Duke shall be entitled, in accordance with the terms of Section 13.2.2, to revise or adjust the level of
credits that Duke previously had provided EMC. 
 11.5 Start-Up Conditions. No later than sixty (60) Days after the Effective Date, Duke shall
conduct a system-wide test of each EMC Demand Side Management Resource Program to determine its capability. Duke shall provide EMC with the results of such test no later than five (5) Business Days after the completion of the system-wide test.
Duke shall not be required to provide credits for EMC Demand Side Management Resource Programs unless the applicable standards and requirements specified for Duke’s Demand Side Resource Management Programs under the riders approved and on file
with the NCUC shall have been met, and the testing provided for in this Section 11.5 shall have been accomplished. 
 11.6 Periodic Testing. Duke
shall have the right periodically, but no less than once per Year, to conduct a system-wide test of each EMC Demand Side Management Resource Program to determine whether the tested EMC Demand Side Management Resource Program is capable of providing
a level of demand reduction equal to the level of the credit that EMC is, at the time of such system-wide test, receiving for such EMC Demand Side Management Resource Program. Subject to Section 11.6.1, if, at the time of such system-wide test,
one or more EMC Demand Side Management Resource Program(s) do not provide the level of demand reduction equal to the level of the credit that EMC is receiving for such EMC Demand Side Management Resource 
  

 61 

 Program(s), Duke shall have the right to (i) reduce the credit provided to EMC to the actual level of demand
reduction provided at the time of the system-wide test and, in accordance with the terms of Section 13.2.2, to revise or adjust the level of credits that Duke previously had provided EMC, and (ii) provide written notice within ninety
(90) Days of the system-wide test, to cancel such EMC Demand Side Management Resource Program(s). 
 11.6.1 Retesting. Within
sixty (60) Days of any failure of a system-wide test for an EMC Demand Side Management Resource Program, EMC shall have the right to have Duke conduct a retest in order to demonstrate that such EMC Demand Side Management Resource Program is
capable of providing the level of demand reduction equal to the level of the credit that EMC previously was receiving for such EMC Demand Side Management Resource Program. To the extent that any such system-wide retest demonstrates that the EMC
Demand Side Management Resource Program is capable of providing demand reduction, the credit provided to EMC shall be restored to the prior level or such lesser level as demonstrated by the result of such rescheduled test and, to the extent
applicable, Duke shall, in accordance with the terms of Section 13.2.2, revise or adjust the level of credits that Duke previously had provided EMC and any notice to terminate rendered by Duke pursuant to 11.6 shall be null and void.

 11.7 EMC Demand Side Management. If Duke’s Annual Planning Period shifts from the Summer Period to the Winter Period, then EMC shall have the
authority to implement and call upon EMC Demand Side Management Resource Programs to control EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the Winter
Period to the level equal to but not below the average of (i) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the immediately preceding
Summer Period and (ii) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the second preceding Summer Period. For example, if (i) the
Annual Planning Period during May 2012 - April 2013 is the Summer Period (May 2012 - September 2012), and the average of EMC’s integrated sixty (60) minute EMC Native Load demands coincident with the twenty (20) highest Hourly Duke
Schedule 1 Demands during such period is 100 MWs; and (ii) the Annual Planning Period during May 2013 - April 2014 is the Winter Period (October 2013 - April 2014), and the average of EMC’s integrated sixty (60) minute EMC Native Load
demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during the Summer Period immediately preceding such Winter Period (i.e., May 2013 - September 2013) is 102 MWs; then EMC may call upon EMC Demand Side Management
Resource Programs to control EMC’s integrated sixty (60) minute EMC Native Loads demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during October 2013 - April 2014 to the level equal to but not below
101 MWs. It is expressly acknowledged that (a) Duke shall also have the right to call upon any available EMC Demand Side Management Resource Program implemented pursuant to this Section 11.7, and (b) EMC shall not be entitled to a
billing credit under Section 11.3 (or any other provision of this Agreement) in connection with any EMC Demand Side Management Resource Program implemented pursuant to this Section 11.7. 
  

 62 

 Article 12 
 Modification of This Agreement 
 12.1 Unilateral Modification. Except as provided in Section 12.3:

 No unilateral modification, amendment or other change to the terms of this Agreement shall be permitted or deemed effective for any reason,
and the rates, terms and conditions specified herein shall not be subject to change through application to FERC pursuant to the provisions of Sections 205 or 206 of the Federal Power Act absent the written agreement of both Parties. Any
amendment or modification to this Agreement shall be deemed enforceable if and only if such amendment or modification (a) has been reduced to writing, (b) has been agreed to and duly executed by both Parties in writing, and (c) has
received all requisite approvals of Governmental Authorities necessary for the effectiveness thereof. Each Party hereby irrevocably waives its rights, including any rights under Sections 205 and/or 206 of the Federal Power Act, to file a
complaint, request an investigation, or make any unilateral rate-change request seeking: (a) an order from FERC finding that any rate or provision in this Agreement is unjust or unreasonable; (b) any refund with respect to this
Agreement’s rates; or (c) any other unilateral modification to this Agreement. Each Party agrees not to make any such unilateral filing or request, and agrees and warrants that these covenants and waivers shall be binding notwithstanding
any regulatory, market, or other change that may occur at any time during the Term. 
 12.2 Mobile-Sierra Public Interest Standard. Except as
provided in Section 12.3, to the extent this Agreement is challenged by any person or its terms are subjected to review under the Federal Power Act or other Laws, the “just and reasonable” standard shall not apply. Instead, absent the
agreement of both Parties to the proposed change, and except as provided in Section 12.3, the standard of review for changes to this Agreement proposed by a Party, a non-party, or FERC acting sua sponte shall be the “public
interest” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956); Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956). 
 12.3 Changes To Certain Charge Components. Notwithstanding anything else herein to the contrary, nothing contained herein shall be construed as affecting in any
way the right of either Party to unilaterally make application to FERC under Sections 205 or 206 of the Federal Power Act (i) to change the depreciation rates and nuclear decommissioning accrual used in Schedule 1, (ii) to
include additional cost items that are incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable, to EMC that are not included in Schedule 1, (iii) to exclude from Schedule 1 cost items
that are no longer incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable to EMC, or (iv) to change Schedule 1 to reflect changes in Duke’s accounting consistent with the Accounting
Requirements (including the addition of new accounts and the removal of obsolete accounts). In addition, in the event that (a) EMC implements new time-of-use rates or materially modifies its existing time-of-use rates, for some or all of
EMC’s Native Load customers, (b) such rates result in a reduction of EMC’s Monthly Billing Demand under Sections 7.2.2.2 or 7.3.2.2, and (c) such Monthly Billing Demand reduction does not result in a commensurate reduction
in the EMC demands that Duke utilizes in Duke’s Generation Planning Practices, Duke may make unilateral application to FERC 
  

 63 

 under Section 205 of the Federal Power Act to change the calculation of the Monthly Billing Demand set forth in
Sections 7.2.2.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. In the event that Duke makes such a filing with FERC, EMC may oppose such filing, and, in addition, shall be free to
propose any other method for calculating the Monthly Billing Demands set forth in Sections 7.2.2.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. 
 12.4 Standard of Review for Permitted Changes. The Parties acknowledge that, as of the Effective Date, FERC has issued a proposed rule that, if adopted, would
specify the language for parties to include in future agreements where the parties intend that the “just and reasonable” standard of review apply to amendments to the agreements. Notwithstanding the language that ultimately may be adopted
by FERC, it is the intent of the Parties that the standard of review that FERC shall apply when acting on proposed modifications to this Agreement that are permitted under Section 12.3, either on FERC’s own motion or on behalf of a
signatory or non-signatory, shall be the “just and reasonable” standard of review rather than the “public interest” standard of review. 
 12.5 Scope of Waiver. Nothing in this Article 12 shall be construed to modify or limit any Party’s right to enforce the express terms of this Agreement as they are written in this Agreement. 
 Article 13 
 Billing and
Payment 
 13.1 Billing Period. Unless otherwise specifically agreed upon by the Parties in the terms of this Agreement or otherwise in writing,
the Month shall be the standard period for determining all billings and payments under this Agreement. 
 13.2 Billing Statements. 
 13.2.1 Initial Statements. After the end of each Billing Period, Duke shall deliver to EMC a statement setting forth for the Billing Period
(i) the sum of the electric energy delivered and/or received for all Hours during that Billing Period, and (ii) Duke’s calculation of any amounts due from EMC under this Agreement for the Billing Period. In addition, in the event that
there are amounts due from Duke to EMC under this Agreement for a Billing Period, EMC shall deliver to Duke, after the end of such Billing Period, a statement setting forth for the Billing Period EMC’s calculation of any amounts due from Duke
under this Agreement for the Billing Period. Notwithstanding the foregoing, a Party’s failure to render a statement as set forth above shall not relieve the other Party from its obligation to make payment to the billing Party when such
statement is rendered, provided such statement is rendered within one (1) year after the end of the Billing Period. 
 13.2.2
Subsequent Payment Adjustments. The Parties understand that in certain cases Monthly billings will need to be made on an estimated basis. In addition, the Parties understand that after-the-fact adjustments to amounts owed or revenues received
may be made in order to reflect correctly the amounts payable by one Party to the other under this Agreement. Each Party 
  

 64 

 shall cooperate in good faith with the other Party to obtain the requisite information and perform the necessary
computations so as to true-up or otherwise adjust any estimated or adjusted billings promptly. 
 13.3 Timeliness of Payment. Unless otherwise agreed
by the Parties, all statements rendered under this Agreement, whether by Duke or EMC, shall be due and payable in accordance with each Party’s statement instructions on or before the later of the twentieth (20th) Day of each Month, or the tenth (10th) Day after receipt of the statement or; if such Day is not a Business Day, then on the next Business Day. Each Party shall make payments in immediately available funds by electronic funds
transfer, or by other mutually agreeable method, to the account designated in writing by the other Party. Any non-disputed amounts (other than amounts for which payment may be withheld pursuant to Section 13.5) not paid by the due date shall be
deemed delinquent and shall accrue interest at the Interest Rate, such interest to be calculated from and including the due date to but excluding the date the delinquent amount is paid in full. 
 13.4 Netting of Payments. The Parties hereby agree that they shall discharge mutual debts and payment obligations due and owing to each other on the same date
through netting, in which case all amounts owed by each Party to the other Party under this Agreement during the Billing Period, including any related interest, payments, and credits, shall be netted so that only the excess amount remaining shall be
paid by the Party who owes it. If no mutual debts or payment obligations exist and only one Party owes a debt or obligation to the other Party during the Monthly Billing Period, including but not limited to any interest, payments, or credits, that
Party shall pay such sum in full when due. 
 13.5 Disputes and Adjustments of Statements. A Party may, in good faith, dispute the correctness of any
statement or any adjustment to a statement, rendered under this Agreement or adjust any statement for any arithmetic or computational error within twenty-four (24) Months of the date the statement, or adjustment to a statement, was rendered. If
a statement or portion thereof, or any other claim or adjustment arising under this Agreement is disputed, the disputing Party shall provide written notice to the other Party (the “Billing Dispute Notice”) which (a) states the good
faith basis for the dispute, (b) specifies the amount in dispute (the “Disputed Amount”), if any, and (c) provides documentation reasonably supporting the determination of the Disputed Amount. The disputing Party shall, at its
option, (a) make payment to the other Party of the Disputed Amount under protest and thereafter shall be reimbursed by the other Party for any amount determined to be refundable after the resolution of such dispute or (b) withhold one half
(1/2) of the Disputed Amount and make payment to the other Party of the other one half (1/2) of the Disputed Amount. Payment to the other Party of one half (1/2) of the Disputed Amount shall not relieve the disputing Party of the
obligation to pay interest accrued at the Interest Rate from and including the date such payment was due to but excluding the date of such payment of any portion of such Disputed Amount withheld and determined to be due and payable after the
resolution of such dispute. Likewise, the other Party shall not be relieved of the obligation to pay interest accrued at the Interest Rate from and including the date such payment was made to but excluding the date of reimbursement of any portion of
such Disputed Amount paid and determined to be refundable after the resolution of such dispute. 
 In the event that a Party, by timely
notice to the other Party, disputes the correctness of a statement or portion thereof or any other claim or adjustment arising under this Agreement, the 
  

 65 

 other Party shall promptly review the disputed statement or adjustment and shall notify the disputing Party, within
forty-five (45) Days following receipt of the Billing Dispute Notice, of the amount of any error or the amount of any payment or reimbursement that the disputing Party is required to make or is entitled to receive. Payments determined to be due
by the disputing Party shall be included on the next Monthly statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date paid. Reimbursements determined to be due from the other Party
shall be included on the next Monthly statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date reimbursed. If the disputing Party disagrees with the other Party’s resolution of
any dispute, then the Parties shall submit the dispute for resolution in accordance with Article 14. 
 Inadvertent overpayments shall
be returned upon request or deducted by the Party receiving such overpayment from subsequent payments, with interest accrued at the Interest Rate from and including the date of such overpayment to but excluding the date repaid or deducted by the
Party receiving such overpayment. Any dispute with respect to a statement is waived unless the other Party is notified in accordance with this Section 13.5 within twenty-four (24) Months after the statement is rendered or any adjustment to
the statement is made. Neither Party shall have the right to challenge any statement, to invoke arbitration of the same or to bring any court or administrative action of any kind questioning the propriety or any other aspect of such statement after
a period of twenty-four (24) Months from the date the statement was rendered; provided, however, that in the case of a statement containing estimates, such twenty-four (24) Month period shall run from the date the statement is adjusted to
reflect the actual amounts due. 
 13.6 Records and Audits. Each Party shall keep such records and documents as may be needed to afford a clear and
complete history of all transactions under this Agreement, and the cost information used to calculate the charges for such transactions, for twenty-four (24) Months following the Month in which such transaction occurs. In addition, during such
twenty-four (24) Month period, EMC shall have the right to audit all records, including phone and computer records, related to Duke’s performance of its obligation not to adversely distinguish against EMC’s Native Load under
Section 4.3.3, Section 6.2, and Section 9.4.2 of this Agreement. If a Party initiates an audit through a notice to the other Party within the time period provided herein, the records and documents related to such audit are required to
be maintained under this Section 13.6, then the other Party will retain such records and documents until such audit is complete. If a Party issues an Original Notice pursuant to Article 14, then the Parties will retain the records and documents
relating to such dispute until the resolution of such dispute. In maintaining such records and documents, EMC and Duke may rely upon the logs and other meter information routinely recorded by Transmission Providers or utilities responsible for
coordination of the purchases and sales. During such twenty-four (24) Month period, either Party, or any Representatives of such Party, shall have the right, at its sole expense and during normal working Hours, to examine the records of the
other Party, including documents and records held by third parties, to the extent reasonably necessary to verify the accuracy of any statement, charge, or computation made pursuant to this Agreement. The Party requesting the audit shall pay the
costs associated with any independent auditor. Upon the request of the auditing Party, the document custodian of the other Party shall certify to the auditing Party that, to the best of such person’s knowledge after reasonable investigation,
the documents and records supplied are true and complete and, in the case of copies, are true, complete and correct copies of the original documents requested by the auditing Party. 
  

 66 

 13.6.1 Procedures. EMC may make a written request for Duke to provide access to documents and
records to verify the accuracy of any statement, charge or computation made pursuant to this Agreement. Within ten (10) Business Days of the receipt of a written request from EMC, Duke shall either provide EMC, or its Representative, with
access to the documents and records which are the subject of the written request or provide EMC with copies of the original documents and records. If Duke elects to provide EMC, or its Representative, with access to the documents and records
requested by EMC, EMC or its Representative shall be permitted to make, at its own expense, copies of the documents and records to which it or its Representative has been provided access. Any copies made by EMC or its Representative shall be subject
to the confidentiality provisions set forth in Section 16.6. If Duke is unable to provide EMC with access or copies within ten (10) Business Days of the receipt of EMC’s written request because it is unable to locate or gain access to
such documents and records after reasonable investigation, Duke shall, within ten (10) Business Days of the receipt of such written request, provide EMC with notice describing the reasons for its failure to provide access to or copies of the
documents and records, its efforts to obtain such documents and records, and its best estimate of the time in which EMC will be permitted access to or provided copies of such documents and records. The twenty-four (24) Month period provided for
in Section 13.5 shall be tolled from the date Duke gives notice describing the reasons for its failure to provide access to or copies of the documents and records until Duke shall have (i) provided EMC with copies or access to all
documents and records specified in EMC’s written request or (ii) Duke’s document custodian shall have certified, that to the best of his knowledge after reasonable investigation that such document does not exist or Duke cannot locate
or produce such document or records. 
 13.6.2 Adjustments Resulting from Audits. If any audit or examination under this
Section 13.6 reveals any inaccuracy in any statement, the necessary adjustments in such statement and the payments thereof shall be made promptly and shall accrue interest at the Interest Rate from the date the overpayment or underpayment was
made until paid; provided, however, that no adjustment for any statement or payment shall be made unless objection to the accuracy thereof was made prior to the lapse of twenty-four (24) Months from the rendition thereof, and thereafter any
objection shall be deemed waived. 
 13.6.3 Confidentiality. The auditing Party shall keep confidential any information obtained in
the audit. If requested, a Party shall provide to the other Party statements evidencing the quantity of electric energy provided under this Agreement for up to the prior twenty-four (24) Months. If an audit is requested with respect to any
records held by the a Party or a third party and those records cannot be disclosed to the requesting Party as a result of a confidentiality obligation, then to the extent legally permissible, the auditing Party shall select an independent auditor to
perform the audit consistent with the Parties’ rights under this Agreement and with such confidentiality arrangements as may be required by the confidentiality obligation in question.

 Article 14 
 Dispute Resolution 
 14.1 Arbitration. Except as otherwise provided below, any dispute arising out of or in
connection with this Agreement or its performance that cannot be resolved after good faith discussions and negotiations between the Parties as set forth in Section 14.2 shall be submitted to binding arbitration. A dispute with respect to
whether a Material Adverse Ruling meets the materiality standard specified in Section 2.3.2.2(c)(1) or (c)(2) shall be subject to dispute resolution pursuant to Section 2.3.2.2.2. A dispute with respect to an invoice shall first be subject
to the procedures set forth in Section 13.5, and if such dispute is not resolved in accordance with such procedures, then such dispute shall be submitted to binding arbitration in accordance with this Article 14. Any arbitration commenced
under this Article 14 shall be conducted in accordance with the North Carolina Arbitration Act, N.C.G.S. Section 1-567 et seq., and the non-administered arbitration rules and procedures of the CPR Institute for Dispute Resolution
(“CPR”) in effect at the time arbitration is commenced, except where specifically modified by this Agreement. 
 14.2 Negotiation and Notice of
Arbitration. Prior to initiating arbitration hereunder, a Party shall provide the other Party with written notice of the dispute, a proposed means for resolving the same, and support for the Party’s position (“Original Notice”).
Thereafter, Representatives of the Parties shall meet in person to discuss the matter and attempt in good faith to reach a negotiated resolution of the dispute. The Parties agree to provide and exchange supporting facts, records and information
regarding the dispute (including calculation and bases) as part of the good faith negotiations. If the Parties have not agreed upon a resolution of the dispute within thirty (30) Days after the provision of the Original Notice or such other
time period as the Parties may agree in writing to allow for discussions and negotiation (“Negotiation Period”), then at any time after the end of the Negotiation Period, a Party may provide written notice to the other declaring an impasse
(“Impasse Notice”) and initiating binding arbitration in accordance with the further provisions of this Article 14. A Party providing an Impasse Notice shall also contemporaneously notify all entities within the EMC Group of the
provision of its Impasse Notice. 
 14.3 Individual, Joint or Consolidated Arbitration. If, within thirty (30) Business Days of EMC’s
provision of an Impasse Notice, Blue Ridge and/or Piedmont also provides an Impasse Notice relating to substantially the same issue as raised by EMC’s Impasse Notice, or if Duke contemporaneously provides each of EMC, Blue Ridge and/or Piedmont
an Impasse Notice relating to substantially the same issue, then each entity within the EMC Group shall have ten (10) Business Days following the expiration of such thirty (30) Business Day period to provide written notification to Duke
stating whether or not such entity will voluntarily proceed in a joint or combined arbitration. 
 If EMC and one or more of the entities
within the EMC Group that have provided or received Impasse Notices within the specified time period relating to substantially the same issue elect to proceed individually or in more than one arbitration proceeding, Duke shall have the right to file
a motion to consolidate such Impasse Notices with EMC’s Impasse Notice in a single proceeding. The motion to consolidate such Impasse Notices shall be served within ten (10)
  

 68 

 Business Days of the date when each entity within the EMC Group has provided notice as to whether or not it will
voluntarily proceed in a consolidated arbitration. Duke’s motion to consolidate shall be decided in the first commenced arbitration by one arbitrator (if the Streamlined Arbitration Process is used) or one (1) arbitration panel (if the
Standard Arbitration Process is used), provided that the arbitrator(s) shall satisfy the qualifications required pursuant to the third sentence of Section 14.6.1(1) or Section 14.6.2(2), as applicable, with respect to all entities in the
arbitration proceedings that are the subject of the motion to consolidate. If Impasse Notices are simultaneously given by EMC and one or more other entities within the EMC Group, then Duke shall have sole discretion to designate which of the Impasse
Notices shall be treated as the first given for purposes of determining which arbitrator(s) shall decide the motion to consolidate, and shall provide written notice of such designation in the motion to consolidate arbitrations. The procedures set
forth in Sections 14.6.1 and 14.6.2 for each arbitration proceeding in which the motion to consolidate was not filed shall be held in abeyance pending the decision on the motion to consolidate by the arbitrator(s) in the arbitration proceeding in
which the motion to consolidate was filed. 
 In determining whether consolidation of one or all is appropriate, the arbitrator(s) shall
consider whether the same or substantially similar issue or issues will be subject to the arbitration(s); EMC’s reasons for opposing consolidation and Duke’s reasons for seeking consolidation; and the fundamental fairness and efficiency in
proceeding individually, jointly or consolidated. The arbitrator(s) decision on the motion to consolidate shall be binding on the Parties and not subject to appeal. 
 In the event the motion to consolidate is denied (unless otherwise agreed by the Parties and the other entities of the EMC Group that have provided or received such Impasse Notices), the arbitrations shall each
proceed, subject to resolution of scheduling issues, with no arbitration being stayed as a result of the denial of the motion. In the event the motion to consolidate is granted, each entity within the EMC Group, other than the entity which is a
party to the proceeding in which the motion to consolidate was filed, shall move for dismissal of the respective arbitration actions in which it is a party. 
 14.3.1 Individual Treatment of EMC in Joint or Consolidated Arbitration. For purposes of joint or combined arbitration, all of the entities within the EMC Group participating in the proceeding shall be treated
as one (1) Party for purposes of Article 14, with the following exceptions. First, EMC shall be treated as a separate Party for purposes of Selection of Arbitration Process set forth in Section 14.4. Second, EMC may reach its own
independent, voluntary resolution with Duke and may pursue its own strategy and prosecute its case with its own legal counsel in the joint or combined arbitration. Third, EMC will be treated as a separate Party for purposes of discovery in
Section 14.6.1(4) or 14.6.2(4). Fourth, EMC will be treated as a separate Party for purposes of a Submission and for the adoption of the resolution and the associated monetary amount with respect to the ultimate decision of the arbitrator(s).
Fifth, EMC will be treated as a separate Party for purposes of the third sentence of Section 14.6.1(1) and Section 14.6.2(2). 
 14.4 Selection
of Arbitration Process. No later than thirty (30) Days following receipt of the Impasse Notice, or any longer time period as agreed to by the Parties, the Parties shall agree on which arbitration process specified herein to use: either the
Standard Arbitration Process or the 
  

 69 

 Streamlined Arbitration Process. Should the Parties fail to agree on the arbitration process within thirty (30) Days
following receipt of the Impasse Notice, then the Standard Arbitration Process shall be used; provided however, that the Streamlined Arbitration Process shall be used for any dispute where the damages in dispute or other monetary value at stake is
alleged to be two hundred fifty thousand dollars ($250,000) or less for EMC or Duke, or in a joint or combined proceeding two hundred and fifty thousand dollars ($250,000) or less for each entity within the EMC Group that is participating in the
proceeding. If the damages in dispute or other monetary value at stake in a combined proceeding is alleged to be two hundred fifty thousand dollars ($250,000) or less for EMC and at least one (1) other of the entities within the EMC Group
participating in a joint or combined proceeding, the Streamlined Arbitration Process shall be used upon the request of either Party (or any of the other entities within the EMC Group participating in the proceeding) made within thirty (30) Days
following the receipt of the Impasse Notices. 
 14.5 Initiation of Arbitration. Unless otherwise agreed by the Parties and except as provided for in
Section 14.3, arbitration shall be deemed to be initiated when the arbitration process is agreed upon or otherwise determined pursuant to Section 14.4 (“Selection Date”). 
 14.6 Arbitration Processes. 
 14.6.1 Standard
Arbitration Process. The following shall be the process that is used, in accordance with this Article 14, as the Standard Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the
purposes of that arbitration alone modify or forego any procedural requirement or rule specified hereunder as part of the Standard Arbitration Process: 
 (1) Selection of Arbitrators. The Party initiating arbitration shall nominate one (1) arbitrator no later than fifteen (15) Days following the Selection Date. The other Party shall nominate one
(1) arbitrator no later than thirty (30) Days after the Selection Date. Each of the two Party-nominated arbitrators shall be unaffiliated with any of the Parties or their predecessors or Affiliates; shall not be current or former employees
of the nominating Party or its predecessors or Affiliates and shall be without material financial alliance with the nominating Party or its predecessors or Affiliates such that said arbitrator is able to participate in the arbitration without
evident partiality or actual bias in favor of the nominating Party; unless such pecuniary interest or affiliation is expressly acknowledged and waived by all Parties. The two (2) arbitrators shall jointly appoint a third (3rd), neutral arbitrator within thirty (30) Days after the
nomination of the second (2nd) arbitrator. The neutral arbitrator shall be the chairperson of the tribunal.
This thirty (30) Day period may be extended to sixty (60) Days by agreement of both Parties. If the two (2) arbitrators are unable to agree on a third (3rd) arbitrator within the specified time period, then a third
(3rd) arbitrator shall be selected by the CPR with due regard given to the selection criteria herein and in the subsequent subsections of Article 14 and input from the Parties and other arbitrators. The Parties shall request CPR to
complete selection of the third (3rd) arbitrator no later than thirty (30) Days following their request
for selection of the arbitrator. Costs charged by CPR for this service shall be borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3,
the costs charged by CPR shall be 
  

 70 

 borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that
participate in such consolidated arbitration. In the event CPR should fail to select the third (3rd) arbitrator
within thirty (30) Days following the Parties’ request for selection of the arbitrator, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the third (3rd) arbitrator. Due regard shall be given to the selection criteria and input from the Parties and other arbitrators. Each of the arbitrators shall
take an oath of neutrality. 
 (2) Additional Qualifications of Arbitrators. Unless otherwise agreed to by the Parties,
each of the arbitrators shall be competent and experienced in matters involving the electricity business in the United States. Such experience shall be conclusively demonstrated by ten (10) years or more of electric industry experience as a
practicing attorney or other experience or expertise as agreed to by the Parties. 
 (3) Replacement of Arbitrators. If
prior to the conclusion of the arbitration any arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein shall be appointed in the manner and timeframe (such timeframe
starting anew following the unavailability of the arbitrator to be replaced) described in Section 14.6.1(1) above. 
 (4)
Discovery. Discovery and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, as determined by a majority of the arbitrators. Each Party shall have the right to
propound up to ten (10) interrogatories, the right to request relevant documents and records, conduct depositions (including depositions of experts), designate experts, and obtain the opinion of opposing experts. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit by overnight
delivery and electronic mail to the arbitrators a precise statement of the dispute, a proposed resolution of the dispute, including a monetary amount and the supporting calculations if applicable, and the factual and/or legal support therefor (the
“Submission”). The next Business Day the Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by
overnight delivery and electronic mail to the other Party and the arbitrators a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) sixty
(60) Days following selection of the third (3rd) arbitrator, (ii) forty-five (45) Days after all pre-hearing discovery has been completed, or (iii) forty-five (45) Days after the issuance of the arbitrators’ decision denying a motion to consolidate
pursuant to Section 14.3, at which the Parties shall present such evidence, argument, and witnesses as they may choose. Prior to the beginning of the hearing, the Parties may submit a joint statement of undisputed facts and/or issues to be
resolved, if the Parties so agree to submit such statement or if the arbitrators order submission of the statement. If the Parties agree, or if allowed by a majority of the arbitrators, the Parties each may submit a post-hearing brief to the
arbitrators within ten (10) Business Days of completion of the hearing. No reply briefs shall be allowed unless otherwise permitted by a majority of the arbitrators. 
  

 71 

 14.6.2 Streamlined Arbitration Process. The following shall be the process that is used, in
accordance with this Article, as the Streamlined Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the purposes of that arbitration alone modify or forego any procedural requirement or
rule specified hereunder as part of the Streamlined Arbitration Process: 
 (1) Selection of Arbitrator. No later than
thirty (30) Days following the Selection Date, the Parties shall agree upon a single arbitrator to conduct the arbitration. If the Parties are unable to agree on an arbitrator, then the arbitrator shall be selected by the CPR with due regard
given to input from the Parties and in conformity with the qualifications specified herein. The Parties shall request CPR to complete selection of the arbitrator no later than thirty (30) Days following their request for selection of an
arbitrator. Costs charged by CPR for this service shall be borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by
CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that participate in such consolidated arbitration. In the event CPR should fail to select the arbitrator within seventy-five (75) Days
after the Selection Date, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the arbitrator. Due regard shall be given to the selection criteria and input from the Parties. The arbitrator shall
take an oath of neutrality. 
 (2) Qualification of the Arbitrator. The arbitrator shall be unaffiliated with any of
the Parties or their predecessors or Affiliates, such that the arbitrator: 
 (a) Shall not be a current or former employee,
advisor, attorney or consultant; 
 (b) Shall be without material financial alliance, such that said arbitrator is able to
participate in the arbitration without evident partiality or bias, unless such pecuniary interest or affiliation is expressly acknowledged and waived by all Parties; 
 (c) Shall be competent in matters involving the electricity business in the United States and shall have ten (10) years or more of
electric industry experience as a practicing attorney or such other experience or expertise as agreed by the Parties; and 
 (d) Shall take an oath of neutrality. 
 (3) Replacement of Arbitrator. If prior to the conclusion of the
arbitration the arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein, shall be appointed in the manner and timeframe (such timeframe starting anew following the
unavailability of the arbitrator to be replaced) described in Section 14.6.2(1) above. 
 (4) Discovery. Discovery
and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, 
  

 72 

 as determined by the arbitrator. Each Party shall have the right to propound up to ten
(10) interrogatories, the right to request relevant documents and records, conduct at least three (3) depositions, in addition to obtaining discovery of the opinions of any experts and the right to depose any experts (which are not
included in the three (3) depositions above). Additional discovery may be conducted only as allowed by the arbitrator or agreed by the Parties. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit a Submission by overnight delivery and electronic mail to the arbitrator. The next Business Day, the
Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by overnight delivery and electronic mail to the other
Party and the arbitrator a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) forty-five (45) Days following selection of the arbitrator,
(ii) forty-five (45) Days after all pre-hearing discovery has been completed, or (iii) forty-five (45) days after the issuance of the arbitrator(s)’ decision denying a motion to consolidate pursuant to Section 14.3, at
which the Parties shall present such evidence, witnesses, and argument as they may choose. Unless otherwise ordered by the arbitrator, at least two (2) Days prior to the beginning of the hearing, the Parties may submit a joint statement of
undisputed facts and/or issues to be resolved if the Parties so agree to submit such statement or if the arbitrator orders submission of the statement. If the Parties agree, or if allowed by the arbitrator, the Parties may each submit a post-hearing
brief to the arbitrator within ten (10) Business Days of completion of the hearing. No reply briefs shall be allowed unless otherwise permitted by the arbitrator. 
 14.7 Decision. The arbitrator (if the Streamlined Arbitration Process is used) or a majority of the arbitrators (if the Standard Arbitration Process is used) shall render his or their decision in favor of one
Party or the other by adopting the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The arbitrator(s) must determine the prevailing Party by interpreting the meaning and intent of the language of
this Agreement, applying the applicable Law to the relevant facts and selecting the arbitration ruling proposed by the Parties that most closely correlated to their decision based upon this Agreement, the applicable Law and the relevant facts. In
rendering the decision, the arbitrator(s) shall interpret and apply the terms and conditions of this Agreement, and consider any relevant evidence and testimony, but shall not have the power to add to or modify any provision of this Agreement or to
recommend any additions or modifications or to render a decision that does not adopt the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The arbitrator(s) shall render a decision within thirty
(30) Days following the later of the conclusion of the hearing or the submission of post-hearing briefs. The decision shall be rendered in writing and shall be final and binding upon the Parties. The decision may be filed in a court of
competent jurisdiction, confirmed and may be enforced by any Party as a final judgment in such court, but shall have no precedential effect on future arbitrations under or arising out of this Agreement except for purposes of enforcement in a court
of competent jurisdiction or for the assertion of collateral estoppel/issue preclusion or res judicata/claim preclusion in another proceeding. The Parties expressly acknowledge that no appeal of the arbitrator’s (or arbitrators’)
decision shall be allowed. Except as provided in Section 16.6.4 of this Agreement, the arbitrator(s) shall have no authority to award special, exemplary, punitive, or consequential damages. 
  

 73 

 14.8 Expenses. The compensation and expenses of the arbitrator(s) shall be chargeable to and borne one-half
(1/2) by Duke and one-half (1/2) by EMC; provided, that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by
the entities within the EMC Group that participate in such consolidated arbitration; provided, however, that each Party shall bear the compensation and expenses of its own counsel and any retained or expert witnesses. Any costs incurred by a Party
in seeking judicial enforcement of any final decision rendered by arbitration conducted under this Article 14 shall be chargeable to and borne exclusively by the Party against whom such court order is obtained. It is expressly acknowledged that the
failure of the entities within the EMC Group that participate in a consolidated arbitration to reach agreement on the allocation of costs among such entities shall not increase Duke’s share of the costs incurred under this Section 14.8 or
Sections 14.6.1(1) or 14.6.2(1) above one-half (1/2) of the total costs at issue. 
 14.9 Effect of Dispute Resolution Procedures. The initiation
of the dispute resolution procedures under this Article 14 shall not affect the Parties’ respective obligations and rights under this Agreement during the pendency of any such procedures. 
 14.10 Confidentiality. The existence, contents, or results of any arbitration proceeding under this Article 14 shall be deemed to be Confidential Information and
shall be subject to the confidentiality provisions set forth in Section 16.6. 
 Article 15 
 Credit and Collateral Requirements 
 15.1 Posting of
Collateral. To protect either Party against potential default of payment or performance, any Party that experiences a Material Adverse Change (“MAC”) shall post as collateral an amount equal to the two (2) highest Months of
Duke’s billings to EMC for the previous twelve (12) Months. Such collateral shall be provided by the Party experiencing the MAC in cash, depository agreements, or letters of credit from a financial institution reasonably acceptable to the
Party not experiencing the MAC within three (3) Business Days after the date on which the MAC occurs. Any such depository agreement or letter of credit shall be in a form satisfactory to the Party not experiencing the MAC in its reasonable
discretion. A financing institution participating in a depository agreement or providing a letter of credit entered into for purposes of this Section 15.1 shall be deemed reasonably acceptable by the Party not experiencing the MAC if it has and
maintains a minimum long term credit rating of A- or better from S&P, A3 or better from Moody’s or A- or better from Fitch Ratings, or is with or from CFC and/or CoBank. 
 15.2 Material Adverse Change. Duke shall be deemed to have experienced a MAC if its unsecured, senior long-term debt obligations not supported by third party credit enhancements are rated below BBB- by S &
P and below Baa3 by Moody’s. EMC shall be deemed to have experienced a MAC (a) if it fails to meet the then-current Debt Service Coverage Ratio required 
  

 74 

 of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three
(3) Years, and (b) the then-current Times Interest Earned Ratio required of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three (3) Years. The failure by either Party to timely
fulfill a payment or reimbursement obligation, including, in the case of Duke a failure to pay Cover Costs, under this Agreement also shall constitute a MAC by that Party. 
 15.3 Continuing Nature of Collateral Requirement. The Party experiencing the MAC must continue to post the collateral until the MAC is cured. The Party not experiencing the MAC shall have the right to draw
upon, use, and dispose of all collateral that is posted under Section 15.1, if the Party experiencing the MAC fails to fulfill any of its payment or reimbursement obligations, including, in the case of Duke a failure to pay Cover Costs, under
this Agreement, and such failure constitutes an Event of Default. In the event any collateral is drawn upon by the Party not experiencing the MAC in accordance with the provisions of Section 15.5, the Party experiencing the MAC shall within
three (3) Business Days fully replenish the collateral to the monetary amount required by Section 15.1. 
 15.4 Interest on Cash Used as
Collateral. Any interest earned on collateral held under a depository agreement with a financial institution shall be paid to the Party posting the collateral in accordance with the terms of the depository agreement. If cash collateral is
posted, the Party holding the cash collateral shall pay interest to the Party posting the cash collateral at the Federal Funds Effective Rate. The Federal Funds Effective Rate is the rate for that Day opposite the caption “Federal Funds
(Effective)” as set forth in the weekly statistical release designated as H.15(519), or any successor publication published by the Board of Governors of the Federal Reserve System. The Party posting the cash collateral shall invoice the Party
holding the cash collateral for interest accrued during the previous Month and the Party holding the cash collateral shall pay such amount within ten (10) Days of receipt of such invoice. 
 15.5 Grant of Security Interest/Remedies. To secure their obligations under this Agreement, any Party posting collateral under Section 15.1 hereby grants to
the Party not experiencing the MAC a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral, cash equivalents collateral and any and all proceeds resulting therefrom or the
liquidation thereof, whether now or hereafter held by, on behalf of, or for the benefit of, that Party, and the posting Party agrees to take such action as the non-posting Party reasonably requires in order to perfect the non-posting Party’s
first-priority security interest in, and lien on (and right of setoff against), such collateral and any and all proceeds resulting therefrom or from the liquidation thereof. Upon or any time after the occurrence or deemed occurrence and during the
continuation of an Event of Default, the Non-Defaulting Party may do any one or more of the following: (i) exercise any of the rights and remedies of a secured party with respect to all collateral, including any such rights and remedies under
Law then in effect; (ii) exercise its rights of setoff against any and all property of the Defaulting Party in the possession of the Non-Defaulting Party or its agent; (iii) draw on any outstanding letter of credit issued for its benefit;
and (iv) liquidate all collateral then held by or for the benefit of the Non-Defaulting Party free from any claim or right of any nature whatsoever of the Defaulting Party, including any equity or right of purchase or redemption by the
Defaulting Party. The Party drawing upon the collateral shall apply the collateral drawn upon or otherwise realized upon the exercise of any rights or remedies granted under this Section 15.5, to reduce the obligations of 
  

 75 

 the Party posting the collateral under this Agreement (the posting Party remaining liable for any amounts owing after

Generation System, and whose unsecured, senior long-term debt obligations not supported by third party credit enhancements are rated BBB- or higher by S&P or Baa3 or higher by Moody’s (or, in the alternative, whose obligations under this
Agreement are guaranteed by a guarantor that meets the foregoing credit standards, provided that the form of the guaranty shall be reasonably satisfactory to EMC). Duke shall be relieved of all liability under this Agreement arising on and after the
effective date of an assignment that satisfies the requirements of subpart (b) above. 
 16.2.1.2 EMC shall not assign this Agreement or
its rights hereunder without the prior written consent of Duke, which consent shall not be unreasonably withheld; provided, however, that EMC may, without the consent of Duke, (a) transfer, sell, pledge, encumber or assign this Agreement or the

Assignment for Security, or (ii) if the Administrator or other secured party first acquires this Agreement, sell, assign, transfer or otherwise dispose of this Agreement to a third party; provided, however, that in either case the Party who
made the Assignment for Security is in default of its obligations to the Administrator or other secured party that are secured by such security interest. 
 16.3 Liability and Indemnification. 
 16.3.1 Indemnity. Each Party shall indemnify, defend, and hold harmless the
other Party from and against:

 16.3.2 Liability Limitations. 
 16.3.2.1 Limitation of Remedies. THE PARTIES CONFIRM THAT THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT SATISFY THE
ESSENTIAL PURPOSES HEREOF. FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE
LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR 
  

 82 

 DAMAGES AT LAW OR IN EQUITY ARE WAIVED REGARDLESS OF THE FAULT, NEGLIGENCE, OR STRICT LIABILITY OF THE PARTY WHOSE
LIABILITY IS RELEASED OR LIMITED THEREBY. 
 IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY HEREIN PROVIDED, AND EXCEPT AS OTHERWISE
EXPLICITLY PROVIDED IN SECTION 16.6.4, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES (INCLUDING INTEREST AS PERMITTED BY APPLICABLE LAW) ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY
AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED (EXCEPT AS PROVIDED IN SECTION 16.29). 
 UNLESS EXPRESSLY HEREIN
PROVIDED, (INCLUDING AS PROVIDED IN SECTION 16.6.4) NO PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, MULTIPLE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR IN
CONTRACT UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY
PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT, OR CONCURRENT, OR ACTIVE OR PASSIVE. 
 16.3.2.2 Disclaimer. EXCEPT AS EXPRESSLY SET
FORTH IN THIS AGREEMENT, EACH PARTY, WITH RESPECT TO THE SUPPLY OF ELECTRIC ENERGY AND CAPACITY TO THE OTHER, EXPRESSLY NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN OR ORAL, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY
REPRESENTATION OR WARRANTY WITH RESPECT TO CONFORMITY TO MODELS OR SAMPLES, MERCHANTABILITY, OR FITNESS FOR ANY PARTICULAR PURPOSE. 
 16.3.2.3 Duty to Mitigate. Each Party agrees that is has a duty to mitigate damages, and each covenants that it shall use commercially reasonable efforts to minimize any damages it may incur as a result of the other Party’s
performance or nonperformance of this Agreement. 
 16.4 Force Majeure. Unless otherwise provided by this Agreement, the term “Force
Majeure” means an event or circumstance that: (i) prevents the Party claiming to be affected by it (the “Claiming Party”) from performing its obligations in whole or in part under this Agreement; (ii) is not within the
reasonable control of the Claiming Party, or the result of the negligence of the Claiming Party, and (iii) by the exercise of due diligence, the Claiming Party is unable to overcome in a commercially reasonable manner, and, without limiting the
scope of the definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court
order or Governmental Authority or arbitration award (so long as the Claiming Party has not sought or has opposed, to the extent reasonable, such actions or restraints). To the extent that the Claiming Party is prevented by Force Majeure from
carrying 
  

 83 

 out, in whole or part, its obligations hereunder and such Party gives notice and details of the Force Majeure to the
other Party (the “Non-Claiming Party”) as soon as practicable, then the Claiming Party shall be excused from the performance of its obligations other than the obligation to make payments then due or becoming due in respect to performance
prior to the Force Majeure, except as otherwise explicitly provided in this Agreement. The Claiming Party shall remedy the Force Majeure event with all reasonable dispatch. The Non-Claiming Party shall not be required to perform or resume
performance of its obligations to the Claiming Party corresponding to the obligations of the Claiming Party excused by Force Majeure during the period that such Force Majeure remains in effect. Duke shall not adversely distinguish between EMC’s
Native Load and Duke’s Native Load in claiming an event of Force Majeure. 
 16.5 Events of Default and Remedies. 
 16.5.1 Events of Default. For the purposes of this Agreement, an “Event of Default” means, with respect to a Party (a “Defaulting
Party”), the occurrence of any of the following: 
 (1) The failure to make, when due, any payment or reimbursement
required by this Agreement (including any amounts to be credited by one Party to the other Party) or to post or maintain collateral required by this Agreement, if such failure is not remedied within three (3) Business Days after receipt of
written notice of such failure is given to the Defaulting Party by the other Party (“Non-Defaulting Party”). For the purposes of this Section 16.5.1(1), withholding one half (1/2) of a Disputed Amount in accordance with
Section 13.5 shall not constitute failure to make, when due, a payment; 
 (2) Any representation or warranty made by
such Party herein is false or misleading in any material respect when made or when deemed made or repeated; 
 (3) The failure
to perform any material covenant or material obligation set forth in this Agreement (except to the extent constituting a separate Event of Default under this Section 16.5), if such failure is not remedied within three (3) Business Days
after receipt of written notice thereof to the Defaulting Party, provided, that a Party’s failure to perform its obligations under Section 16.1.2.1(iii) or Section 16.1.2.2(iv) shall not in and of itself constitute a material failure
to perform a material covenant or material obligation unless such failure, in the case of Duke, results in a substantial and continuing degradation in reliability of service hereunder or, in the case of EMC, results in a substantial and continuing
degradation in performance hereunder; 
 (4) Such Party becomes Bankrupt; 
 (5) The loss of any authorization from Governmental Authorities necessary to perform its obligations hereunder in accordance with the
terms of this Agreement; 
 (6) Such Party consolidates or amalgamates with, or merges with or into, or transfers all or
substantially all of its assets to, another entity and, at the 
  

 84 

 time of such consolidation, amalgamation, merger, or transfer, the resulting, surviving, or transferee
entity fails to assume all of the obligations of such Party under this Agreement to which it or its predecessor was a party by operation of law or pursuant to an agreement reasonably satisfactory to the other Party; 
 (7) The occurrence and continuation of a default, event of default, or other similar condition or event that under one or more agreements
or instruments, individually or collectively, relating to indebtedness for borrowed money in an aggregate amount of not less than twelve million dollars ($12,000,000) in the case of EMC or one hundred fifty million dollars ($150,000,000) in the case
of Duke, that results in the Party’s indebtedness under such agreements or instruments to become immediately due and payable; and 
 (8) With respect to such Party’s guarantor, if any: 
  

	 	(a)	if any representation or warranty made by a guarantor in connection with this Agreement is false or misleading in any material respect when made or when deemed made or repeated;

  

	 	(b)	the failure of a guarantor to make any payment required or to perform any other material covenant or obligation in any guaranty made in connection with this Agreement and such
failure shall not be remedied within three (3) Business Days after written notice; 

  

	 	(c)	a guarantor becomes Bankrupt; 

  

	 	(d)	the failure of a guarantor’s guaranty to be in full force and effect for purposes of this Agreement (other than in accordance with its terms); or 

  

	 	(e)	a guarantor shall repudiate, disaffirm, disclaim, or reject, in whole or in part, or challenge the validity of any guaranty. 

 16.5.2 Notice of Event of Default. In the event a Party becomes aware of any event or circumstance that constitutes an Event of Default, such
Party shall promptly notify the other Party in writing and by telephone. 
 16.5.3 Effect of Event of Default. If at any time an Event
of Default with respect to a Defaulting Party has occurred and is continuing, the other Party (the “Non-Defaulting Party”) may do one or more of the following: 
 (1) If an Event of Default under Section 16.5.1(1) persists for ten (10) Days or longer, terminate this Agreement in accordance
with the notification required pursuant to Sections 2.3.2.1 and 2.3.3 of this Agreement; or 
  

 85 

 (2) If an Event of Default (other than an Event of Default under Section 16.5.1(1))
persists for sixty (60) Days or longer, terminate this Agreement in accordance with Sections 2.3.2.1 and 2.3.3 of this Agreement, provided, however, that if the Defaulting Party is diligently pursuing cure, but such Event of Default is not
capable of being cured within sixty (60) Days, then the period for the Defaulting Party to cure such Event of Default shall be extended from sixty (60) Days to one hundred eighty (180) Days before the Non-Defaulting Party may exercise
its right to terminate this Agreement pursuant to this Section 16.5.3(2). 
 16.5.4 Enforcement of Remedies. The Non-Defaulting
Party may exercise any rights or remedies available at law or equity, subject to the provisions of Article 14 and Sections 15.5 and 16.3 of this Agreement. No delay or failure on the part of a Non-Defaulting Party to exercise any right or
remedy to which it may become entitled on account of an Event of Default shall constitute an abandonment of any such right, and the Non-Defaulting Party shall be entitled to exercise such right or remedy at any time during the continuance of an
Event of Default notwithstanding any delay in enforcing such right. No waiver of any Event of Default shall constitute a waiver of any later Event of Default; all such waivers shall be in writing and shall in no circumstance be deemed effective
unless such waiver is made in writing. All of the remedies and other provisions of this Section 16.5 shall be without prejudice and in addition to any right of setoff, recoupment, combination of accounts, lien, or other right to which any Party
or any of its Affiliates is at any time otherwise entitled, whether by operation of law or in equity, under contract, or otherwise. 
 16.6 Confidential
Information. 
 16.6.1 Prior Confidentiality Agreements Unaffected. Any preexisting confidentiality agreements entered into by the
Parties pertaining to the negotiation and development of this Agreement shall survive by their terms and shall not be considered modified by this Agreement. 
 16.6.2 Authorized Disclosure. Each Party agrees to preserve, to the maximum extent permitted by Law, the confidentiality of Confidential Information supplied to it by the other Party either during the
negotiations leading to this Agreement or during the course of implementing, performing or winding up this Agreement. A Party may disclose Confidential Information received from the other Party to the receiving Party’s Affiliates, auditors,
attorneys, consultants, advisors, persons providing financing to the receiving Party, other entities in the EMC Group that have entered into substantially similar agreements, and to other third parties as may be necessary for the receiving Party to
perform its obligations under this Agreement, provided that any such persons agree in writing to be bound by the confidentiality provisions of this Agreement. Notwithstanding anything contained in this Section 16.6, Confidential Information may
be disclosed to any Governmental Authority requiring such Confidential Information, provided that: (i) such Confidential Information is submitted under applicable provisions, if any, for confidential treatment by such Governmental Authority;
(ii) prior to such disclosure, the Party who supplied the information is given notice of the disclosure requirement (if time permits and the other Party’s counsel determines that such notice is permitted by Law) so that it may take at its
own risk and expense whatever action it deems appropriate, including intervention in any proceeding and the seeking of an injunction to prohibit such disclosure; and (iii) the Party subject to the Governmental Authority endeavors to protect the
confidentiality of 
  

 86 

 any Confidential Information to the extent reasonable under the circumstances and to use its good faith efforts to
prevent the further disclosure of any Confidential Information provided to any Governmental Authority. The Parties recognize that Duke is required to file periodic reports with FERC that disclose certain price, quantity, and related data, and such
filings shall not be deemed a violation of this section. 
 16.6.3 Survival of Confidentiality Obligations. Confidential Information
received from the other Party shall be kept confidential in accordance with the terms of this Agreement for at least five (5) Years after the termination of this Agreement. 
 16.6.4 Right to Remedies. In the event of an unauthorized disclosure to a third party, the limitations on remedies contained in
Section 16.3.2.1 shall not apply, and, in the event of a breach, Parties shall not have an adequate remedy at law and accordingly shall, in addition to any other available legal or equitable remedies, be entitled to an injunction against such
breach without any requirement to post a bond as a condition of such relief. 
 16.7 Governmental Liabilities. 
 16.7.1 Minimization of Tax Liability. Each Party shall use reasonable efforts to implement the provisions of and to administer this Agreement in
accordance with the intent of the Parties to minimize all taxes, so long as neither Party is materially adversely affected by such efforts. 
 16.7.2 Governmental Charges. 
 16.7.2.1 With respect to sales of electric energy made by Duke to EMC, Duke shall pay or cause
to be paid all Governmental Charges imposed by any Government Authority on or with respect to such sales of electric energy to the extent such Governmental Charges arise prior to the Delivery Point. EMC shall pay or cause to be paid all Governmental
Charges on or with respect to such sale of electric energy to the extent such Governmental Charges arise after the Delivery Point (other than ad valorem, franchise, or income taxes that are related to the sale of such product and are, therefore, the
responsibility of Duke). 
 16.7.2.2 With respect to sales of electric energy by EMC to Duke, EMC shall pay or cause to be paid all
Governmental Charges on or with respect to the sale of the electric energy to Duke. 
 16.7.2.3 In the event a Party is required by Law to
remit or pay Governmental Charges that are the other Party’s responsibility hereunder, the Party ultimately liable for the Governmental Charge shall promptly reimburse the remitting Party for such Governmental Charges; provided further that tax
liabilities may be netted pursuant to Section 13.4 of this Agreement. Nothing will obligate or cause a Party to pay or be liable to pay any Governmental Charges for which it is exempt under the Law. 
 16.7.3 Records. If with respect to either Party, any purchase or sale of electric energy is exempt from Governmental Charges it shall, upon
written request of the other Party, provide a certificate of exemption or other reasonably satisfactory evidence of exemption, and shall use reasonable efforts to obtain and cooperate with obtaining any exemption from or reduction of any
Governmental Charges. 
  

 87 

 16.7.4 Cost of Obtaining FERC Approval. The Parties agree that all fees assessed by FERC, or
expenses incurred in obtaining the approval of FERC for this Agreement, shall be the sole responsibility of Duke. 
 16.7.5 Cost of
Obtaining RUS Approval. The Parties agree that all fees assessed by the RUS, or expenses incurred in obtaining the approval of RUS for this Agreement, shall be the sole responsibility of EMC. 
 16.8 Choice of Law. The validity, interpretation and performance of this Agreement and the rights and duties of the Parties arising out of this Agreement
shall be governed by and construed, enforced, and performed in accordance with the Laws of the State of North Carolina. No principle, doctrine, or rule of conflicts of law shall modify or alter the applicability of the Laws of the State of North

 Schedule 1 
 Annual Production Capacity and Energy Rates 
 Schedule 1 Methodology: 
 This formula sets forth the method that Duke will use to determine its annual Demand Rates, Fuel Rates, and Variable O&M Rates (collectively, “Rates”). The
Rates will be annual formula rate calculations. The Rates shall initially be estimated for the period January 1, 2007 - December 31, 2007, and shall be estimated continuing thereafter for successive twelve month periods (e.g., January 1,
2008 - December 31, 2008, etc.). Beginning July 1, 2008, and each July 1 thereafter, the Rates will be trued-up based on actual costs and loads for the most recent calendar year, using the formula rates set forth below. The calculations
will be based on Duke’s FERC Form 1 data and Duke’s company records. The true-up will include interest on any refunds or surcharges calculated in accordance with the methodology set forth in 18 C.F.R. § 35.19a or its successor. The
formulas for the Rates were designed to include all costs incurred by Duke to own, operate and maintain Duke’s Generation System. The formulas for the Rates may only be amended by the mutual agreement of the Parties or pursuant to
Section 12.3 of the Agreement. Disallowance or any other treatment of any such costs by the NCUC or any other Governmental Authority other than FERC will not have any effect on the inclusion of such costs in the formulas for the Rates as set
forth below.

to the extent such sales are not included in the determination of Duke’s Average Peak Hour Load, less fuel recovered from such sales as determined in the Fuel Rate below, multiplied by 2/3. 

  

	 	IV.	Fuel Rate 

 The Fuel Rate shall equal F/S, and further
divided by the Revenue Tax Rate, where: 
 F is the expense of fossil and nuclear fuel and purchased economic power, as defined in 18 C.F.R.
§ 35.14(a)(2) (2005), for the calendar year period; provided that for purposes of this calculation described in 18 C.F.R. § 35.14(a)(2) (2005) the cost of fossil fuel shall include, in addition to those items set forth in 18
C.F.R. § 35.14(a)(6), expenses recorded in Account No. 509 for the calendar year period. 
 S is all kWh sold (compensated for
losses to the point at which power is available for transmission ), excluding inter-system sales, for the calendar year period. 
  

	 	V.	Variable O&M Rate 

 The Variable O&M rate shall
equal Variable Non-Fuel Production Operation and Maintenance Expense divided by S as determined in Section IV above, and further divided by the Revenue Tax Rate.

 II. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During
Light Load Periods (through December 31, 2008) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour
shall be subject to reduction during the period commencing on the Commencement Date and continuing through December 31, 2008 in accordance with the following: 
 A. NCEMC’s contractual right to SO 1996, SOR A and SOR E (654.3 MW rounded to 655 MW) is subject to reduction based on a comparison between 655 MW and NCEMC’s CP&L Native Load (NCNL). 
 B. In the event that NCEMC’s CP&L Native Load during the Hour is less than 655 MW, EMC’s Base Obligation and EMC Group’s Base
Obligation for the Hour shall be reduced as follows: 
 C. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC’s
Base Obligation shall be equal to the amount set forth in Equation 1 below: 
 Equation 1: ( ( 655 MW - NCNL ) / 225 ) * 17 
 D. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC’s Base Obligation shall be equal to 17 MW plus the amount set forth in Equation
2 below: 
 Equation 2: ( ( 430 MW - NCNL ) / 225 ) * 17 
  

 3 

 E. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC Group’s Base
Obligation shall be equal to the amount set forth in Equation 3 below: 
 Equation 3: ( ( 655 MW - NCNL ) / 225 ) * 33 
 F. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC Group’s Base Obligation shall be equal to 33 MW plus the amount set forth in
Equation 4 below: 
 Equation 4: ( ( 430 MW - NCNL ) / 225 ) * 33 
 G. Example: If NCNL is equal to 565 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 655 MW – 565
MW ) / 225 ) * 17 or 6.8 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( (655 MW - 565 MW) / 225 ) * 33, or 13.2 MW. 
 III. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods (January 1, 2009 through December 31, 2010) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour shall be subject to reduction during the period commencing on
January 1, 2009 and continuing through December 31, 2010 in accordance with the following: 
  

 4 

 A. NCEMC’s contractual right to SO 1996 and SOR A (429.3 MW rounded to 430 MW) is subject to
reduction based on a comparison between 430 MW and NCEMC’s CP&L Native Load (NCNL). 
 B. In the event that NCEMC’s CP&L
Native Load during the Hour is less than 430 MW, EMC’s Base Obligation for the Hour shall be reduced as follows: 
 Equation 5: ( (430
MW - NCNL ) / 225 ) * 17 
 C. In the event that NCEMC’s CP&L Native Load during the Hour is less than 430 MW, EMC Group’s Base
Obligation for the Hour shall be reduced as follows: 
 Equation 6: ( ( 430 MW - NCNL ) / 225 ) * 33 
 D. Example: If NCNL is equal to 340 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340
MW ) / 225 ) * 17 MW, or 6.8 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340 MW ) / 225 ) * 33, or 13.2 MW. 
 IV. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods for the Catawba Resource Entitlement 
 In addition to the reductions to EMC’s Base Obligation and EMC Group’s Base Obligation set forth under Sections II and III above, EMC’s
Base Obligation and EMC Group’s Base Obligation shall be subject to reduction as set forth in this Section IV. 
  

 5 

 A. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a
nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC’s Base Obligation for the Hour shall be reduced as follows: 
 Equation 7: (1 - ( NDNL / 623.5 MW) ) * 47 MW 
 B. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC Group’s Base Obligation
for the Hour shall be reduced as follows: 
 Equation 8: (1 - ( NDNL / 623.5 MW ) ) * 95 MW 
 C. Example: If NDNL is equal to 561.15 MW during an Hour, and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the
Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( 1 - ( 561.15 MW / 623.5 MW) ) * 47 MW, which equals ( .1 ) * ( 47 MW ), or 4.7 MW, and the reduction in EMC Group’s
Base Obligation for the Hour shall be equal to ( 1 - ( 561.15 MW / 623.5 MW ) ) * 95 MW, which equals ( .1 ) * ( 95 MW ), or 9.5 MW.

 Force Majeure: “Force Majeure” means an event or circumstance which prevents one Party from
performing its obligations under one or more Transactions, which event or circumstance was not anticipated as of the date the Transaction was agreed to, which is not within the reasonable control of, or the result of the negligence of, the Claiming
Party, and which, by the exercise of due diligence, the Claiming Party is unable to overcome or avoid or cause to be avoided. Force Majeure shall not be based on (i) the loss of Buyer’s markets; (ii) Buyer’s inability
economically to use or resell the Product purchased hereunder; (iii) the loss or failure of Seller’s supply; or (iv) Seller’s ability to sell the Product at a price greater than the Contract Price. Neither Party may raise a claim
of Force Majeure based in whole or in part on curtailment by a Transmission Provider unless (i) such Party has contracted for firm transmission with a Transmission Provider for the Product to be delivered to or received at the Delivery Point
and (ii) such curtailment is due to “force majeure” or “uncontrollable force” or a similar term as defined under the Transmission Provider’s tariff; provided, however, that existence of a Force Majeure absent a showing
of other facts and circumstances which in the aggregate with such factors establish that a Force Majeure as defined in the first sentence hereof has occurred.

	 Intervals 676-900 - Put Signal during each Interval (kW)
	  	9,000	  	0	  	9,000	  	14,000

  

	3	Interval numbers refer to the Intervals during the Hour (e.g., Interval 1 is the first four seconds of the Hour, Interval 2 is the next four seconds, etc.). The Call
and Put Signals are shown as the same in each of the first 225 Intervals of the Hour, and then again as the same in the next 225 Intervals and so on. This is a simplifying assumption, to make this example less cumbersome. In actual operation, the
Parties anticipate that these positions would change frequently within the Hour.

 C. Incremental/Decremental Costs 
  

	
	 Duke Territorial Incremental Cost: $0.10/kWh

	 Duke Territorial Decremental Cost: $0.10/kWh

  

	4	These numbers sum the four-second Call and Put Signals from Part I.A. For example, 6,000 kW delivered by Duke in each of the 225 four-second Intervals (15 minutes)
equal 1,500 kWh (6,000 KW * 225 Intervals / 900 Intervals / Hour = 1500 kWh).

 Attachment 7-4 
 Example 2 
 Showing the Calculation of Blue Ridge, Piedmont and 
 Rutherford Allocated Shares of the Duke Total Hourly Energy Charge, 
 EMC Group Total Hourly Energy Credit, Inter-EMC Energy Charge and Inter-EMC Energy Credit 
 The
purpose of this attachment is to provide an example showing the calculation of the charges and credits identified above for one Hour. For purposes of this example, Blue Ridge, Piedmont and Rutherford are referred to individually as BR, P and R,
respectively, and collectively as the EMC Group.

	39	Interval numbers refer to the Intervals during the Hour (e.g., Interval 1 is the first four seconds of the Hour, Interval 2 is the next four seconds, etc.). The Call
and Put Signals are shown as the same in each of the first 225 Intervals of the Hour, and then again as the same in the next 225 Intervals and so on. This is a simplifying assumption, to make this example less cumbersome. In actual operation, the
Parties anticipate that these positions would change frequently within the Hour.

 C. Incremental/Decremental Costs 
 Duke Territorial Incremental Cost: $0.10/kWh 
 Duke Territorial Decremental Cost: $0.10/kWh 
 II. CALCULATIONS 
 A. Calculation of Blue Ridge, Piedmont and Rutherford Allocated Shares of the Duke Total Hourly Energy Charge 
 Step 1 
 Sum the energy deliveries by Duke to BR for all Intervals over
the entire Hour (column 1). Repeat calculation for P and R (columns 2-3). Sum columns 1-3 (column 4). Sum the energy deliveries by Duke to the EMC Group for all Intervals over the entire Hour (column 5). 
  

	40	These numbers sum the four-second Call and Put Signals from Part I.A. For example, 3,000 kW delivered by Duke in each of the 225 four-second Intervals (15 minutes)
equal 750 kWh (2,000 KW * 225 Intervals / 900 Intervals / Hour = 750 kWh).

 ATTACHMENT 7-9 
 Demand Rate Adjustment Percentage and Annual Percentage 
 This attachment provides the formulas to be used for calculating
the Demand Rate Adjustment Percentage and Annual Percentage for each calendar year beginning January 1, 2011. 
 The Demand Rate Adjustment Percentage
shall equal the Production Capacity Revenue Requirement Adjustment divided by the Original Production Capacity Revenue Requirement, but not less than zero. 
 Where 
 Production Capacity Revenue
Requirement Adjustment = (Annual Percentage – 4%) * (Original Production Capacity Revenue Requirement + Original Energy Revenue Requirement) 
 And 
 Annual Percentage shall equal the product of the System Gross Plant Difference and the Fixed Charge Rate,
divided by the sum of Original Production Capacity Revenue Requirement and Original Energy Revenue Requirement. For purposes of calculating the Production Capacity Revenue Requirement Adjustment, the Annual Percentage shall be a maximum of 10%.

 System Gross Plant Difference shall equal EMC Plant in Service less NC Retail Plant in Service. (May be positive or negative.) System Gross Plant
Difference shall be decreased as necessary to eliminate differences between EMC Plant in Service and NC Retail Plant in Service related to timing or method of recovery of plant costs (e.g., plant differences due to recovery of construction period
financing costs through inclusion of construction work in progress in rate base). 
 Fixed Charge Rate shall equal
10%. 
 EMC Plant in Service shall equal the average of the total ending balance of Production Plant, General Plant and Intangible Plant according to
Schedule 1 of this Agreement, for the calendar year for which the Production Capacity Revenue Requirement calculation is prepared and total ending balance of Production Plant, General Plant and Intangible Plant according to Schedule 1 of this
Agreement for the previous calendar year calculation of the Production Capacity Revenue Requirement. 
 NC Retail Plant in Service shall equal the sum
of Duke Power Retail Plant in Service and Nantahala Retail Plant in Service, which shall be determined from Company records supporting the total Electric Plant in Service amount on Schedule 3 of NCUC Form E.S.-1 for the 12 month calendar period
corresponding to the Production Capacity Revenue Requirement calculation used for calculating the EMC Plant in Service. 

 Duke Power Retail Plant in Service shall equal the average of the two December balances for the total of
Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly amounts shown on Schedule 3 of NCUC Form E.S.-1 for Duke Power. 
 Nantahala Retail Plant in Service shall equal the average of the two December balances for the total of Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly
amounts shown on Schedule 3 of NCUC Form E.S.-1 for Nantahala Power & Light. 
 Original Production Capacity Revenue Requirement shall equal
the Production Capacity Revenue Requirement before consideration of any adjustments pursuant to Section 7.3.2.3 of the Agreement. 
 Original Energy
Revenue Requirement shall equal the sum of F for purposes of calculating the Fuel Rate in Schedule 1 and Variable Non-Fuel Production Operation and Maintenance Expense for purposes of calculating the Variable O&M Rate in Schedule 1.

 Attachment 8-1 
 (Part I of II) 
 TERMS AND CONDITIONS 
 FOR THE SCHEDULING OF POWER 
 SUPPLIED BY NORTH CAROLINA 
 ELECTRIC MEMBERSHIP CORPORATION 
 TO
ITS INDEPENDENT MEMBERS 

 All NCEMC Committed Resources associated with the Wholesale Power Supply Agreement between the Seller and
the Buyer are governed by and subject to all of the terms and conditions in this Exhibit, unless a specific Resource Summary Attachment explicitly provides otherwise. Unless defined in this Exhibit, all capitalized terms used herein shall have the
respective meanings set forth as Article One of the Wholesale Power Supply Agreement. 
 General Principles 
  

	1.	Buyer is responsible for planning the way it chooses to use any Capacity or Energy delivered pursuant to one of the Resource Summary Attachments governed by this Exhibit. As a part
of the Wholesale Power Supply Agreement, the Parties have agreed to a set of Resource Summary Attachments that collectively are intended to represent a financial approximation of an allocation of the NCEMC Committed Resources on the Effective Date.

  

	2.	For any hour of delivery, Seller will optimize resources around final dispatch for the combined load of all of Seller’s Participating Members, plus the schedules of the Buyer
and other Independent Members. 

  

	3.	Buyer will pay Seller charges for Energy and the delivery of Energy to the Interface Point under terms specified in Resource Summary Attachments and terms specified elsewhere in
this Agreement including but not limited to Sections 2.4, 2.12 and Article Five. 

 Delivery of Allocated Resources 
  

	4.	Energy Scheduled from Buyer’s Independent Member Allocation is delivered to the Interface Point. The cost and expense of all transmission services, including ancillary services
and losses, from the Interface Point are the sole responsibility of Buyer. 

  

	5.	Seller will be deemed the provider of the resources needed for the purposes of tagging and for the designation of resources under the applicable tariffs of the Transmission
Provider(s) selected by Buyer. 

 Scheduling by Buyer 
  

	6.	All Schedules from Buyer for each Independent Member Allocation will be in whole MWs and may not exceed the IM Allocation MW detailed on the Resource Summary Attachment.

  

	7.	Buyer will submit a separate Schedule in conformance with this Exhibit S by System by resource up to the Maximum Scheduling Limit by System, as further described in Paragraph 23 of
this Exhibit S. 

  

	8.	Buyer will be responsible for scheduling and arranging for the delivery of its SEPA allocation. 

  

 -2- 

	9.	For any Independent Member Allocation that is designated as producing Must-Take Energy, Buyer is required to Schedule for every hour of every day of the Delivery Period its full
Must-Take Energy obligation from such a resource, and may not amend or reduce its Schedule for that Energy: provided, however, that to the extent that Seller’s obligation to purchase Must-Take Energy from a resource designated as producing
Must-Take Energy is reduced in any hour, Buyer’s hourly Must-Take Energy obligation shall be adjusted by the ratio of Seller’s hourly Must-Take Energy obligation to the Resource Capacity, rounded to whole MWs. The Buyer shall not be
entitled to Schedule Must-Take Energy in an hour in amounts, which exceed the Buyer’s adjusted Must-Take Energy obligation for that hour. 

  

	10.	Buyer is obligated to Schedule resources in accordance with the terms and conditions provided in the Resource Summary Attachments consistent with the minimum run times in the
contracts pertaining to Seller’s purchased and/or owned resources, and Seller will use its good faith efforts to accommodate Buyer’s Schedules that do not meet the minimum run time requirements, but only so long as meeting such
non-conforming Schedules would not likely result in additional costs to Seller or any of its Participating Members. 

  

	11.	Except with respect to Buyer’s Independent Member Allocations that supply Must-Take Energy, Buyer is not obligated to Schedule its Independent Member Allocations consistent
with the minimum volumes in the power supply contracts of Seller that are in force on the Independent Member Effective Date. 

  

	12.	By 7:00 a.m. EPT each day Buyer must provide Seller with an hourly forecast of its load by System for the following day. 

  

	13.	The Buyer may Schedule its resources consistent with the table below. Day-ahead Schedules are those submitted before 8:00 a.m. EPT the day prior to flow. Intra-day Schedules are
those that are requested after the 8:00 a.m. EPT deadline above. All Schedule changes must occur at the top of the hour. Intra-day Schedule changes require two (2) hours advance notice. 

  

			
	 Scheduling
Changes

	 Day Ahead
	 	 Intra-Day

		
	Unlimited changes up to the IM Allocation MW identified in the Resource Summary Attachment for each resource in whole MWs.	 	Up to two changes to the hourly Schedule for the remainder of the day. Each change to the hourly Schedule shall be no greater than 5%, for a cumulative maximum of 10% each hour. Additional
changes will be accommodated on a best efforts basis.

  

 -3- 

 Scheduling by Seller 
  

	14.	Seller is not obligated to meet Buyer’s final Schedule using the NCEMC Committed Resources associated with the Independent Member Allocations Scheduled by Buyer.

  

	15.	Seller will accept the risk and/or benefit resulting from differences in the cost of resources used to provide Buyer Energy in accordance with its Schedule(s), and the costs Seller
would have incurred had it used NCEMC Committed Resources to meet Buyer’s Schedule of the Scheduled resource(s). 

  

	16.	Should Seller acquire an alternate resource, rather than use an NCEMC Committed Resource to serve Buyer’s Schedule, and that alternate resource is curtailed, Buyer’s
Schedule will be maintained and any penalty, benefit or curtailment will be borne by Seller. 

  

	17.	Should all or any portion of NCEMC Committed Resources that have been Scheduled by Seller and Buyer to meet Buyer’s Schedule in any given hour be interrupted, then Seller shall
try to identify available alternate resources which Seller, in its sole discretion, determines are reasonably priced and suitable to meet Seller’s needs. If Seller determines that such alternate resources are available, Seller may maintain the
Scheduled deliveries to Buyer but at a price to be determined by Seller and communicated to Buyer. If no alternate resources are available to Seller, Buyer’s Schedule will be curtailed. All damages recovered by Seller from the Person
responsible for the interruption in service will be shared with Buyer and every other Member similarly affected by such interruption in service. 

 Operations and Planning 
  

	18.	Buyer will provide Seller with a real time telemetered signal of Buyer’s load for Seller’s use, for purposes of determining when to start and stop the dynamic schedule,
and to Schedule certain Must-Take Energy requirements of NCEMC Committed Resources. 

  

	19.	Seller shall provide and inform the Buyer on each Thursday by 1:00 p.m. EPT of the projected amount of Energy available hourly by Independent Member Allocation by System for
Scheduling by Buyer for the following Saturday through Friday period, including the amount of Must-Take Energy that will be delivered and must be taken hourly. 

  

	20.	By 8:00 a.m. EPT each day, Buyer shall provide an hourly forecast of its Native Load by System for the next seven (7) days. For purposes of this Exhibit S, “Native
Load” shall mean only the load of Buyer’s members. This load forecast will be used by Seller to calculate the hourly Energy available from the Independent Member Allocations that are available to be Scheduled for a given interval of time.

  

	21.	Buyer shall provide Seller on each Thursday by 4:00 p.m. EPT, a projected hourly Schedule of all the Independent Member Allocations governed by this Agreement for the following
Saturday through Friday period. 

  

 -4- 

	22.	Seller and Buyer agree on the following checkout and verification process: 

  

	    	As soon as practical after midnight, confirm hourly Schedules, energy flows and energy charges by resource and daily totals; 

  

	    	Provide a contact person each Business Day for the following: 

  

	    	Resolve issues that remain unresolved; 

  

	    	Perform month-to-date confirmations of hourly Schedules, energy flows and energy charges by resource and daily totals; 

  

	    	Finalize monthly checkouts by the second Business Day of the following month; and Coordinate any true-ups that may be required. 

  

	23.	For Buyers having loads in more than one System, Buyer will provide at the Independent Member Election Date and on July 1 of each subsequent year, a forecast of the percentage
of its retail load in each System. (The sum of the percentages must equal 100%). The Maximum Scheduling Limit by System for the following calendar year will be calculated by multiplying the percentage of Buyer’s retail load in each System times
the total of Buyer’s Independent Member Allocations for the following calendar year.

 Attachment 8-1 
 (Part II of II) 
 TERMS AND CONDITIONS 
 FOR OBTAINING TRANSMISSION 
 SERVICES ADEQUATE TO DELIVER 
 FROM THE INTERFACE POINTS 
 ESTABLISHED UNDER THE 
 WHOLESALE POWER SUPPLY AGREEMENT 
 OF NCEMC FOR SALES TO 
 ITS INDEPENDENT MEMBERS 
  

 -6- 

 General Principles and Responsibilities for Transmission: All Resource Summary Attachments associated with
the Wholesale Power Supply Agreement between Seller and Buyer are governed by and subject to the terms and conditions in this Exhibit unless a specific Resource Summary Attachment explicitly provides otherwise. For purposes of this Exhibit, the
Wholesale Power Supply Agreement and each Resource Summary Attachment governed by this Exhibit, the term “Acceptable Transmission Service” means the level of service available at any point in time that is equal to or better than that level
of service currently defined as “Network Integration Transmission Service” under the Open Access Transmission Tariff of the System to which Buyer’s distribution system is physically interconnected, and if connected to more than one
System, then Buyer must have Acceptable Transmission Service for each Interface Point. 
 The following terms for transmission service apply to each Resource
Summary Attachment included as a part of this Agreement. All of these terms assume that the current Open Access Transmission Tariff environment in force on the Effective Date remains in force, without modification or amendment. The Parties hereto
agree that any amendment, modification or change to that tariff or the regulatory environment for the wholesale electric industry, whether by regulation, regulatory action, statute, judicial action, executive decision or order, or otherwise, may
require modification of this Exhibit to restore to Buyer and Seller the benefits that each intended. Such amendments, modifications or changes would include, without limitation, any changes or modifications of the wholesale electric industry
environment based on the Standard Market Design, or the restructuring of the transmission systems or the regulatory oversight of same. If the Parties fail to reach agreement on modifications of this Exhibit, the dispute shall be subject to
arbitration under the Wholesale Power Supply Agreement. 
 Buyer is responsible for planning for and scheduling the receipt of capacity and energy to be
delivered to Buyer. Buyer will be responsible for negotiating, making and keeping in force one or more transmission agreements with the Transmission Provider(s) necessary to perform its obligations under the Wholesale Power Supply Agreement. At a
minimum, Buyer will negotiate, make and keep in force its own Network Integration Service Agreement (“NITSA”) and its own Network Operating Agreement (“NOA”). 
 Subject to and contingent upon the concurrence and agreement of each affected Transmission Provider, the RUS, and the Federal Energy Regulatory Commission (“FERC”), the Parties further agree: 
  

	1.	Buyer is responsible for serving its own load. It will do so through contracts with Seller, along with other resources Buyer will acquire. 

  

	2.	Buyer will have its own transmission agreement(s) with each and any Transmission Provider(s) whose services are needed to move capacity or energy from any Interface Point of the
System(s) to which Buyer’s distribution system is physically interconnected. 

  

	3.	Buyer will negotiate its own NITSA and NOA. Seller will provide assistance with these negotiations as requested. The cost for this assistance will be charged to Buyer separately
from charges for Capacity and Energy billed under Article 5.1 of this Agreement. 

  

 -7- 

	4.	Seller will transfer the direct-assigned facilities used for that Buyer, if any, to Buyer’s NITSA once the same has become effective. 

  

	5.	Seller will provide Buyer with contractual rights that financially approximate the hypothetical assignment of a total amount of Seller’s owned and/or purchased resources,
calculated in accordance with the NCEMC Member Power Supply Resource Policy, for purposes of Buyer’s NITSA and NOA designations for energy delivered to the System served by the Transmission Provider with which Buyer has entered its NITSA and
NOA. 

  

	6.	If any need exists or arises to designate, in addition to the contracts with Seller, any other network resources in order to meet Buyer’s load in accordance with the tariffs or
other requirements of the Transmission Provider(s), Buyer has the responsibility to locate, identify and designate such other network resources. 

  

	7.	Buyer will have the obligation to satisfy the requirements of the applicable OATT, and purchase or self-supply, as applicable, any ancillary or other services needed or required to
serve its load. 

  

	8.	Buyer will coordinate with Seller or its scheduling agent under Exhibit S to this Wholesale Power Supply Agreement to assure that the proper schedule is in place each day for
Buyer’s scheduled amount of Energy related to each of Buyer’s Resource Summary Attachments that are governed by this Exhibit. 

  

	9.	In addition to the other responsibilities arising under this Exhibit, Buyer shall be solely liable for any energy imbalance settlement and any other settlements or liabilities to
which a Transmission Customer is exposed at and from the Interface Point(s). If Buyer causes Seller to incur energy imbalance charges, Buyer will reimburse Seller for any charges that Seller incurs.

ending December 31, 2031, and so forth thereafter. 
 2.3.2 Early Termination. Notwithstanding the provisions of
Section 2.3.1, early termination of this Agreement, including any Extension Term, shall only be permitted in the six (6) circumstances set out in Sections 2.3.2.1, 2.3.2.2, 2.3.2.3, 2.3.2.4, 2.3.2.5 and 2.3.2.6. 
 2.3.2.1 Early Termination for an Event of Default. In the event that an Event of Default occurs, and the Defaulting Party fails to cure such Event
of Default within the time period(s) specified in Section 16.5.3, the Non-Defaulting Party may terminate this Agreement upon giving thirty (30) Days’ Notice of Termination, provided that the termination date shall be the last Day of a
Month. 
 2.3.2.2 Early Termination for a Material Adverse Ruling. In the event that a Material Adverse Ruling occurs, the Party
affected by such Material Adverse Ruling may, within twenty (20) Days after such Material Adverse Ruling occurs, give the other Party Notice of Termination, in accordance with Section 2.3.3, of its intent to terminate this Agreement
effective on 23:59:59 of the last Day of the Month that is twenty-four (24) Months after the Month in which the Notice of Termination is given. Such termination date shall be referred to herein as the “Material Adverse Ruling Termination
Date.” If a Party fails to give Notice of Termination within twenty (20) Days after a Material Adverse Ruling occurs, it shall have permanently waived its right to terminate this Agreement due to such Material Adverse Ruling pursuant to
this Section 2.3.2.2. Termination pursuant to this Section 2.3.2.2 shall be subject to the following procedures: 
 (a) During the ninety (90) Days immediately following the giving of the Notice of Termination, the Parties shall attempt to negotiate amendments to this Agreement that would permit the Parties to restore the equivalent value of the
economic bargain contemplated by this Agreement absent the Material Adverse Ruling. If the Parties reach agreement, such amendments will not become effective unless, within one 
  

 22 

 hundred eighty (180) Days of the date that the Notice of Termination is given, the Parties have
obtained the necessary approvals of Governmental Authorities to enable the amendments to become effective without change, condition or modification. In the event that the Parties fail (i) to reach agreement on such amendments, or (ii) to
obtain the necessary approvals of Governmental Authorities, this Agreement shall terminate on the Material Adverse Ruling Termination Date, subject to the provisions of Section 2.3.2.2(b) and 2.3.2.2.2. 
 (b) In the event that the Parties are unable to reach agreement on the amendments provided in Section 2.3.2.2(a), either Party may,
no later than ninety (90) Days after the date that the Notice of Termination is given (or, if earlier, the date that the Parties mutually agree that they are unable to reach agreement on such amendments), give notice to the other Party of its
desire to extend this Agreement for a period of up to twelve (12) Months beyond the Material Adverse Ruling Termination Date. Such extension will be subject to the Parties (i) having first reached agreement upon the rates, terms and
conditions of service for such twelve (12) Month period within one hundred twenty (120) Days of the date that the Notice of Termination is given and executing such agreement within such one hundred twenty (120) Day period, and
(ii) having received from Governmental Authorities the necessary approvals for such rates, terms and conditions without change, condition or modification within one hundred eighty (180) Days of the date that the Notice of Termination is
given. 
 (c) A “Material Adverse Ruling” is an order or action by a Governmental Authority or a change in Law that
(i) either (A) modifies the rates, terms, or conditions of this Agreement, (B) disallows the recovery from EMC of costs that are included in this Agreement, (C) for retail ratemaking or regulatory accounting and reporting
purposes, disallows costs related to this Agreement, including any disallowance of Duke’s costs related to investments in generating facilities or binding contracts to purchase electric capacity and energy to provide service to EMC under this
Agreement, or (D) for retail ratemaking or regulatory accounting and reporting purposes, assigns, allocates or makes pro forma adjustments with respect to the revenues or costs related to this Agreement, and (ii) adversely affects the
relative economic position of either Party in a material way. For purposes of this definition only, 
 (1)
“material” for Duke means that the effect of the order or action by the Governmental Authority or change in Law is reasonably projected to decrease Duke’s net revenues under this Agreement, or, in the case of a disallowance,
assignment, allocation, or pro forma adjustment of revenues or costs for retail ratemaking or regulatory accounting or reporting purposes, either (i) decrease Duke’s net costs or increase Duke’s net revenues assigned or allocated to
Duke’s retail customer classes, or (ii) increase Duke’s net costs or decrease Duke’s net revenues assigned or allocated to Duke’s wholesale customer class, by an aggregate amount equal to five percent (5%) or more of
the total revenues to be paid by EMC to Duke under this Agreement over the then-remaining Term; 
 (2) “material”
for EMC means that the effect of the order or action by the Governmental Authority or change in Law is reasonably projected to increase 
  

 23 

 EMC’s net costs under this Agreement by an amount equal to five percent (5%) or more of the
total revenues to be paid by EMC to Duke under this Agreement over the then-remaining Term; 
 (3) an increase in a
Party’s net costs is the increase in the Party’s costs as a result of the order or action by the Governmental Authority or change in Law, less the increase (if any) in the Party’s revenues as a result of the Material Adverse Ruling;
and 
 (4) a decrease in a Party’s net revenues is the decrease in the Party’s revenues as a result of the order or
action by the Governmental Authority or change in Law, less the decrease (if any) in the Party’s costs as a result of the Material Adverse Ruling. 
 (d) The foregoing amounts shall be calculated on a nominal rather than an inflation adjusted or present value basis. Without limitation of the foregoing, EMC acknowledges that, for retail ratemaking and regulatory
accounting and reporting purposes, Duke shall calculate the costs of the electric capacity and energy used to serve EMC under this Agreement on a system average cost basis beginning January 1, 2007. EMC agrees that if the amount of costs that
the NCUC or the PSCSC in effect assigns or allocates to, or requires Duke to assign or allocate to, this Agreement for ratemaking or regulatory accounting and reporting purposes exceeds Duke’s system average costs, such action shall constitute
a Material Adverse Ruling if the five percent (5%) materiality standard set forth above is met. 
 2.3.2.2.1 A change in Duke’s
net revenues or EMC’s net costs that results from a change in this Agreement that is permitted under Section 12.3, shall not constitute a Material Adverse Ruling regardless of the impact of such change on either Party’s net costs or net
revenues. 
 2.3.2.2.2 In the event that either Party believes that a Material Adverse Ruling has occurred, the Party affected by such
Material Adverse Ruling shall provide the other Party a good faith calculation together with information supporting the calculation of the projected effect of the Material Adverse Ruling and include such calculation and the cost information
supporting the calculation with the Notice of Termination. If the non-terminating Party notifies the other Party, within twenty (20) Days following the date that such Notice of Termination is given, of its good faith objection to the
calculation or the cost information supporting the calculation of the projected effect of the Material Adverse Ruling, then the Parties shall, within thirty (30) Days following the date that such Notice of Termination is given (the
“Resolution Period”), attempt to resolve their differences with respect to the calculation or the cost information supporting such calculation. If, at the conclusion of the Resolution Period, the Parties are not in agreement with respect
to the calculation or cost information supporting the calculation, then PriceWaterhouseCoopers, or such other nationally recognized accounting firm that is not then the independent auditor for either Party or any of its Affiliates or predecessors
and is selected by mutual agreement of the Parties (the “Neutral Auditors”), shall be engaged within ten (10) Days after the expiration of the Resolution Period to review the calculation and the cost information supporting the
calculation and to make an independent determination as to 
  

 24 

 whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as
applicable. If the Neutral Auditors require any additional information, records, or internal analysis to make a determination as to whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2),
as applicable, the Party in possession of such information, records or internal analysis will provide it to the Neutral Auditors. Each Party agrees to execute, if requested by the Neutral Auditors, a reasonable engagement letter, including customary
indemnities. All fees and expenses relating to the work to be performed by the Neutral Auditors shall be borne one-half (1/2) by the terminating Party and one-half (1/2) by the non-terminating Party. The Neutral Auditors shall act as an
arbitrator to determine, based upon its independent review, whether the Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable. The Neutral Auditors’ determination shall be made
within thirty (30) Days of their selection, shall be set forth in a written statement delivered to both Parties and shall be final, binding and conclusive. If the Neutral Auditors’ determine the materiality standard set forth in
Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met, the Notice of Termination shall be null and void. If the Neutral Auditors’ determine the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is
met, the Notice of Termination shall be effective in accordance with its terms. The initiation of the dispute resolution process described in this Section 2.3.2.2.2, shall not toll or otherwise delay running of the twenty-four (24) Month
time period set forth in the Notice of Termination, unless the Neutral Auditors’ find that the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, is not met. The procedure set forth in this
Section 2.3.2.2.2 shall be the exclusive means for the Parties to resolve any dispute as to whether a Material Adverse Ruling meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2). If a Party gives a Notice of
Termination based on its good faith contention of the occurrence of a Material Adverse Ruling that meets the materiality standard set forth in Section 2.3.2.2(c)(1) or (c)(2), as applicable, and the Neutral Auditors subsequently determine that
such materiality standard has not been met, such Party shall not be in default under this Agreement solely because it gave such Notice of Termination. 
 2.3.2.3 Early Termination for Failure of Condition Precedent. This Agreement may be terminated for failure of a condition precedent in accordance with Section 3.5.2.2 or Section 3.5.3. 
 2.3.2.4 Early Termination Due to Implementation of Retail Competition. Upon the date of enactment of a Law providing for implementation of retail
electric service competition on a comprehensive basis in the State of North Carolina, the Parties shall enter into negotiations with the goal of reaching agreement on amendments to this Agreement to provide for the continuation of the purchase and
sale of electric capacity and energy and the provision of Scheduling Agent Services provided for in this Agreement after the commencement of such retail electric service competition. If the Parties are not able to reach agreement by the latter to
occur of (i) the date that is ninety (90) Days after the date of enactment of such Law or (ii) the date that is twenty-four (24) Months prior to the commencement of such retail electric service competition in the State of North
Carolina, then this Agreement shall terminate automatically on the date such retail electric service competition commences in the State of North Carolina without the need for either Party to give notice. 
  

 25 

 2.3.2.5 Early Termination Due to Plant Calculation. In the event that the Annual Percentage
calculated in Attachment 7-9 is positive for two (2) consecutive Years, and the absolute value of such percentage is greater than ten percent (10%) then EMC may, within twenty (20) Days after the date in such second
(2nd) consecutive Year that Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4, give Duke Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month that is twenty-four
(24) Months after the Month in which the Notice of Termination is given. In the event that the Annual Percentage calculated in Attachment 7-9 is negative for two (2) consecutive Years, and the absolute value of such percentage is
greater than ten percent (10%) for any two (2) consecutive Years, then Duke may, within twenty (20) Days after the date in such second (2nd) consecutive Year that Duke provides the calculation of the Annual Percentage pursuant to
Section 7.3.2.4, give EMC Notice of Termination to terminate this Agreement effective on 23:59:59 of the last Day of Month that is twenty-four (24) Months after the Month in which the Notice of Termination is given. If a Party fails to
give Notice of Termination within twenty (20) Days after Duke provides the calculation of the Annual Percentage pursuant to Section 7.3.2.4 for such second (2nd) consecutive Year, it shall have permanently waived its right to
terminate this Agreement under this Section based on the Annual Percentage for such two (2) consecutive Years; provided, that nothing in this Section 2.3.2.5 shall affect any Party’s termination rights under Sections 2.3.2.1,
2.3.2.2, 2.3.2.3, 2.3.2.4 or 2.3.2.6. 
 2.3.2.6 Early Termination Due to Extended Force Majeure. If, as a result of an event of Force
Majeure, a Party is unable to meet a material obligation hereunder for a period greater than ninety (90) Days, then the Non-Claiming Party shall have the right to terminate this Agreement upon giving a Notice of Termination within thirty
(30) Days of the expiration of such ninety (90) Day period; provided, however, if the Claiming Party has used and continues to use all Commercially Reasonable Efforts to remedy, cure or mitigate the event of Force Majeure, then the
Non-Claiming Party’s right to give Notice of Termination shall be suspended for so long as the Claiming Party continues to use Commercially Reasonable Efforts to remedy, cure or mitigate the event of Force Majeure. 
 2.3.3 Form of Notice of Termination. Notice of Termination made pursuant to Sections 2.2 or 2.3 shall be given in accordance with
Section 16.22 and shall state (i) the date of termination being effectuated, and (ii) the provision of this Agreement under which termination is being effectuated and the basis for the termination. Except as otherwise provided in this
Section 2.3.3, the Notice of Termination is effective when it is deemed given in accordance with Section 16.22. Once the Notice of Termination is given to a Party, it shall not be deemed amended, modified, or otherwise revoked for any
reason (other than a determination by the Neutral Auditors pursuant to Section 2.3.2.2.2 that the materiality standard is not met) unless such amendment, modification, or revocation is mutually agreed to by both Parties in writing or unless the
Parties reach agreement in accordance with Section 2.3.2.2(a). Upon receipt of the Notice of Termination, the non-terminating Party shall acknowledge receipt in writing sent in accordance with Section 16.22 within five (5) Business
Days of the receipt of the Notice of Termination. Acknowledgment of a Notice of Termination is a courtesy and shall not influence the effectiveness of the termination. Failure to utilize a method specified in Section 16.22 shall not influence
the effectiveness of the termination if the Notice of Termination is actually received by the Chief Executive Officer of the non-terminating Party within thirty (30) Days of 
  

 26 

 the date of the Notice of Termination, in which case the Notice of Termination shall be effective on the date that the
Notice of Termination is actually received by the Chief Executive Officer of the non-terminating Party. 
 2.4 Absolute Nature of Termination. Both
Parties hereby acknowledge, warrant, and agree that TERMINATION OF THIS AGREEMENT FOR ANY REASON PROVIDED FOR AND PERMITTED UNDER THIS AGREEMENT IS ABSOLUTE AND FOREVER EXTINGUISHES ANY AND ALL OBLIGATIONS EXISTING UNDER THIS AGREEMENT FOR
(A) DUKE TO PLAN OR PROCURE RESOURCES TO SERVE EMC, OR TO PROVIDE ANY SERVICE OR PRODUCT TO EMC, (B) EMC TO PURCHASE FROM AND PAY DUKE FOR ANY SERVICES OR PRODUCTS, (C) EMC TO PLAN OR PROCURE RESOURCES TO SERVE DUKE, OR TO PROVIDE ANY
SERVICE OR PRODUCT TO DUKE, AND (D) DUKE TO PURCHASE FROM AND PAY EMC FOR ANY SERVICES OR PRODUCTS. Upon termination of this Agreement in accordance with Section 2.2, 2.3, 3.5.2.2, or 3.5.3, each and every obligation of Duke to provide
electric energy and capacity and Scheduling Agent Services to EMC, and each and every right of EMC to purchase electric energy and capacity and Scheduling Agent Services from Duke shall cease as a matter of contract and neither Party shall claim or
assert any continuing right to continued performance, whether by “rollover,” as an “evergreen” service, or in any other fashion based on this Agreement. By entering into this Agreement, Duke does not commit, and shall not be
deemed to have committed, to plan its system to be able to provide any service to EMC beyond the Term, and EMC agrees that it has no claim to any service beyond the Term. EMC shall not at any time oppose any filing by Duke to cancel this Agreement
as a rate schedule under the Federal Power Act concurrently with, or subsequently to, the termination of this Agreement as a contract in accordance with Section 2.2, 2.3, 3.5.2.2, or 3.5.3. The Parties acknowledge, warrant, and agree that it is
the express intention of the Parties that no action by any Governmental Authority may override the terms of this Section 2.4 of this Agreement, and that should any Governmental Authority take any action purporting to, or that might be claimed
to, override the terms of this Section 2.4, either directly or indirectly, EMC shall not make any claim or assert any right based on or relying on such Governmental Authority action in any manner that conflicts with or frustrates the terms of
Section 2.4 of this Agreement.

 Article 4 
 Sale of Electric Capacity and Energy 
 4.1 Classification of Services Provided. During the period beginning on the Commencement Date,
and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, Duke shall provide to EMC “FFR Supplemental Service”, as described in Section 4.2. Beginning January 1, 2011, throughout the
remainder of the Term of this Agreement, Duke shall provide to EMC “Partial Requirements Service”, as described in Section 4.3. 
  

	4.2	FFR Supplemental Service. 

 4.2.1 Character of
FFR Supplemental Service. For each Hour during the period beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, Duke shall sell and deliver, and EMC shall
purchase and receive, all of the electric capacity and energy that EMC requires to serve EMC’s Native Load in excess of EMC’s Base Obligation for such Hour. For example, if EMC’s Native Load during an Hour is 800 MWs, and EMC’s
Base Obligation for such Hour is 600 MWs, Duke shall supply and deliver, and EMC shall purchase and receive, 200 MWs of FFR Supplemental Service for such Hour. Duke shall supply and deliver FFR Supplemental Service in a manner that is as firm as,
and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load. Duke shall be responsible for maintaining the generation reserves needed to meet its FFR Supplemental Service obligation. Notwithstanding anything in this
Agreement to the contrary, Duke shall have no obligation to sell and deliver any electric capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.2.2 Amount of EMC’s Base Obligation. EMC’s Base Obligation for each Hour beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is
in effect, shall be as set forth in Attachment 4-1. 
  

 34 

 Notwithstanding the preceding sentence, EMC’s Base Obligation shall be subject to modification (a) during Light
Load Periods in accordance with the provisions of Attachment 4-2 or (b) in accordance with the provisions of Section 5.1.4 and 5.1.5. The amounts set forth on Attachment 4-1 reflect MWs delivered at a Delivery Point.

 4.2.3 Scheduling To Meet EMC’s Base Obligation. In order to meet EMC’s Base Obligation, (a) MSCG shall be
responsible for scheduling to the Transmission Provider electric energy under the PPA to serve EMC’s Native Load and (b) Duke, acting as Scheduling Agent, shall be responsible for scheduling to the Transmission Provider, in accordance with
the provisions of Article 8, electric energy to serve EMC’s Native Load from EMC’s entitlements to the resources described in Section 5.1.3, 5.1.4 or 5.1.5. The total amount of electric energy so scheduled to the Transmission Provider
in any Hour to serve EMC’s Native Load beginning on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall be the EMC Scheduled Amount; provided that the EMC
Scheduled Amount shall not exceed EMC’s Base Obligation for any such Hour. 
 4.2.4 Scheduling Shortfall. For each Hour beginning
on the Commencement Date, and continuing through December 31, 2010, or any portion thereof in which this Agreement is in effect, if, for any reason, including a Force Majeure as that term is defined herein or a “force majeure”,
“uncontrollable force” or a similar term defined in a third-party agreement, but not including Duke’s unexcused failure to comply with the provisions of Article 8, the EMC Scheduled Amount is less than EMC’s Base Obligation for
any Hour, there shall be a “Scheduling Shortfall” in the amount equal to the difference between EMC’s Base Obligation and the EMC Scheduled Amount in such Hour (“Scheduling Shortfall Amount”). For any Hour that Duke receives
information or a notice pursuant to Section 8.4.8 that there will be or has been a Scheduling Shortfall, Duke shall use Commercially Reasonable Efforts to procure and supply electric energy in a quantity sufficient to supply the Scheduling
Shortfall Amount for such Hour (“Replacement Energy”). In the event that, through the exercise of Commercially Reasonable Efforts, Duke procures Replacement Energy from a third party for resale to EMC, EMC shall pay Duke for the total cost
incurred by Duke to purchase and deliver the Replacement Energy. Duke’s curtailment of a Non-Firm Sale shall constitute a procurement of Replacement Energy from a third party and the total cost incurred by Duke shall be (i) the foregone
sales price for the Non-Firm Sale curtailed and (ii) if applicable, any charges imposed for changes to schedules for the sale of electric energy. In the event that Duke supplies Replacement Energy from its own resources, EMC shall pay Duke for
such Replacement Energy an amount equal to one hundred ten percent (110%) of Duke’s System Incremental Cost in supplying such Replacement Energy. The total charges for Replacement Energy for a Month, as determined by this
Section 4.2.4, shall constitute the Monthly Replacement Energy Charge. 
 4.2.4.1 It is expressly understood that Section 4.2.4
shall not be construed or interpreted to (i) require Duke to curtail any Firm Sales in order to supply Replacement Energy to EMC, (ii) to curtail any Non-Firm Sales except as set forth in Section 4.2.6 in order to supply such
Replacement Energy to EMC, (iii) impose upon Duke any responsibility for providing Replacement Energy for a Scheduling Shortfall that occurs after the Transmission Provider’s deadline for scheduling transmission service required for the
delivery of such Replacement Energy, or (iv) affect in any way EMC’s rights and obligations under its Network Integration Transmission Service Agreement. 
  

 35 

 4.2.4.2 In the event that there is or is expected to be a Scheduling Shortfall in connection with
(a) EMC or its Scheduling Agent having received notice (and in the event EMC receives notice providing Duke with evidence of such notice) of, or (b) pursuant to Section 8.4.8 Scheduling Agent having received notice of either
(i) the occurrence of a “force majeure” event under the PPA, as defined in Section 4.2.4.3, or (ii) the temporary impairment of generating resources underlying the WPSA, the SEPA Contract, or other resources to which EMC may
have an entitlement pursuant to Section 5.1.3, 5.1.4 or 5.1.5, such that all or a portion of EMC’s entitlements to electric energy under such agreements are or will be temporarily unavailable to EMC, then EMC may request Duke to sell
electric capacity and energy to EMC for the expected duration of such Scheduling Shortfall. In the event that EMC makes such a request, Duke shall exercise Commercially Reasonable Efforts to offer to supply electric capacity and energy to EMC under
rates, terms, and conditions that Duke determines to be commercially reasonable. If the Parties reach agreement on such a sale, then Duke shall sell and deliver and EMC shall purchase and receive the electric energy and such electric energy shall be
included in EMC Scheduled Amount. 
 4.2.4.3 For purposes of Section 4.2.4.2, the term “force majeure” means an event or
circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in part; (ii) is not within the reasonable control of the claiming party, or the result of the negligence of the claiming
party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable manner, and, without limiting the scope of the definition, includes acts of God, or the public enemy, or insurrection,
riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court order or governmental authority or arbitration award (so long as the claiming party has
not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission service interruptions or curtailments imposed by a transmission provider in response to transmission capacity or
availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 4.2.4.3. 
 4.2.5
EMC PPA Obligation. EMC shall retain all of its rights and obligations under the PPA, including the obligation to pay all costs incurred under the PPA. 
 4.2.6 EMC Obligation to Curtail Load. During any Hour in which there is a Scheduling Shortfall, and either (i) Duke does not replace such electric energy in accordance with Section 4.2.4 or
(ii) EMC has not made, or does not have in place, arrangements to replace such electric energy, EMC shall curtail an amount of EMC’s Native Load equal to the Scheduling Shortfall Amount; provided, however, Duke shall exercise Commercially
Reasonable Efforts within the time constraints that exist to first call upon any available EMC Demand Side Management Resource Program that would not otherwise be called upon absent the Scheduling Shortfall and then if necessary curtail Non-Firm
Sales to the extent of the Scheduling Shortfall before requiring EMC to curtail EMC’s Native Load pursuant to this Section 4.2.6. Any such EMC Native Load that has been curtailed shall be restored when the Scheduling Shortfall is no longer
occurring or when the Scheduling Shortfall has been replaced either by electric energy supplied (a) by Duke in accordance with Section 4.2.4 or this Section 4.2.6 or (b) under arrangements made by EMC with third parties.

  

 36 

	4.3	Partial Requirements Service. 

 4.3.1 Character
of Partial Requirements Service. For each Hour during the period beginning on January 1, 2011, and continuing through the termination of this Agreement, Duke shall sell and deliver, and EMC shall purchase and receive, all of the electric
capacity and energy that EMC requires to serve EMC’s Native Load in excess of the EMC Contract Resources. Duke shall be responsible for maintaining the generation reserves necessary to meet this obligation. Duke shall supply Partial
Requirements Service in a manner that is as firm as, and otherwise comparable with, the manner in which Duke supplies Duke’s Native Load. Notwithstanding anything in this Agreement to the contrary, Duke shall have no obligation to sell and
deliver any electric capacity or energy to EMC that is not required to serve EMC’s Native Load. 
 4.3.2 Scheduling of EMC Contract
Resources To Serve EMC Native Load. For each Hour beginning on January 1, 2011, and continuing through the Term of this Agreement, EMC’s contractual entitlement to electric energy from the Dispatched Combined Cycle Resources and from
the Baseload Resources shall be scheduled in accordance with the provisions of Sections 4.3.3 and 4.3.4, respectively. 
 4.3.3
Scheduling of the Combined Cycle Resources. Duke may schedule, in accordance with Attachment 4-3 and Article 8, each of the Combined Cycle Resources pursuant to Duke’s economic dispatch as necessary to serve Duke’s total
electric energy obligations. Duke shall make no adverse distinction against the Combined Cycle Resources in determining the dispatch order of Duke’s Generation System and the Combined Cycle Resources. The Combined Cycle Resources that Duke
schedules pursuant to economic dispatch shall be referred to as the “Dispatched Combined Cycle Resources”. Except as provided in Section 4.3.3.1 and Section 4.3.3.2, EMC shall be solely responsible for all costs associated with
the Combined Cycle Resources. 
 4.3.3.1 Duke shall not be obligated to pay for any costs that EMC incurs as a result of Duke’s dispatch
of the Combined Cycle Resources to the extent that Duke’s dispatch of such Combined Cycle Resources is for the purpose of serving Duke’s Native Load and, during any Year, Duke’s dispatch of a Combined Cycle Resource for that purpose
does not exceed an Annual Capacity Factor of twenty percent (20%). In the event and at such time during a Year that Duke’s dispatch of a Combined Cycle Resource to serve Duke’s Native Load exceeds an Annual Capacity Factor of twenty
percent (20%), Duke shall pay EMC, in the manner and time provided for in Article 13, the additional Energy Cost that EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource for the remainder of the Year. For example, if
a Dispatched Combined Cycle Resource has a generating capacity of one hundred (100) MWs during a Year and, as of 11:59:59 on November 30 of such Year, Duke has dispatched such resource for 175,200 MWhs for the purpose of serving
Duke’s Native Load, Duke shall reimburse EMC for the Energy Costs that EMC incurs in December of such Year as a result of Duke’s dispatch of such Dispatched Combined Cycle Resource. For the purpose of this Section 4.3.3.1,
“Annual Capacity Factor” means the total amount of electric energy generated by a Dispatched Combined Cycle Resource for the purpose of serving Duke’s Native Load during a Year divided by the product of (a) the total generating
capacity of such Dispatched Combined Cycle Resource and (b) 8,784 (during a leap year) or 8,760 (during a Year other than a leap year), multiplied by one hundred percent (100%). 
  

 37 

 4.3.3.2 In the event that Duke’s dispatch of one or more of the Combined Cycle Resources is for any
purpose other than to serve Duke’s Native Load, Duke shall pay EMC, in the manner and time provided for in Article 13, the additional Energy Cost that EMC incurs as a result of Duke’s dispatch of such Combined Cycle Resource(s).

 4.3.3.3 For purposes of Sections 4.3.3.1 and 4.3.3.2, “Energy Cost” means, with respect to any Dispatched Combined Cycle
Resource, all variable costs incurred by EMC that are associated with the production of electric energy under the WPSA, including the cost of fuel, start charges, and any other variable charges incurred by EMC under the WPSA in connection with the
electric energy dispatched by Duke from such Combined Cycle Resource regardless of NCEMC’s actual generating cost or NCEMC’s contractual source of the electric energy. 
 4.3.4 Scheduling of Baseload Resources. Duke shall schedule, in accordance with Article 8, all of the Baseload Resources to the full extent
that EMC’s entitlement to such resources are available to EMC and such electric energy shall be used to serve EMC’s Native Load. EMC shall be solely responsible for all costs associated with the Baseload Resources. The Baseload Resources
that Duke schedules pursuant to this Section 4.3.4 shall be referred to as “Dispatched Baseload Resources”. 
 4.4 Excepted Load.
Notwithstanding anything to the contrary herein, Duke shall have no obligation to supply electric capacity or energy required by EMC to serve Excepted Load. Excepted Load shall consist of EMC load that is either (a) Non-Conforming Load or
(b) Non-Duke Control Area Load. Non-Conforming Load shall consist of (i) EMC load resulting from the merger of EMC with another electric membership corporation or other entity (except to the extent such load was, at the time of the merger,
already being served by Duke under an agreement substantially similar to this Agreement), and (ii) EMC wholesale load (except as provided in Section 4.4.1). Non-Conforming Load shall also consist of discrete EMC load (a) to which
electric service from EMC shall have commenced after the Effective Date, (b) that has a projected peak demand in excess of twenty-five (25) MW for the Year in which electric service from the EMC commences, and (c) which is projected
to change within a one-minute period by a significant quantity on a recurring basis due to the nature of the retail customer’s operations (e.g., without limitation, an arc furnace). 
 4.4.1 New River Load. If, on or before December 31, 2010, EMC notifies Duke that it desires to include New River as a part of EMC’s
Native Load under this Agreement, the New River load shall not be a Non-Conforming Load and shall be EMC’s Native Load for purposes of this Agreement; provided that New River’s load shall be included as EMC’s Native Load for a period
of not less than five (5) Years. It is expressly understood that New River shall not be included as a part of EMC’s Native Load beyond the Term. It is further expressly understood that nothing contained in this Section 4.4.1 shall
restrict Duke’s right or ability to make an offer to meet New River’s electric energy requirements under separate arrangements that may be agreed to by Duke and New River. 
 4.5 Good Title. Electric energy that is delivered by Duke to EMC shall be free and clear of all liens, Claims, and encumbrances at the Delivery Points, where title to electric energy provided by Duke hereunder
shall transfer to EMC. Electric energy that is delivered by EMC to Duke shall be free and clear of all liens, Claims, and encumbrances at the point where title to the electric energy is transferred to Duke. 
  

 38 

 4.6 Power Quality. All electric energy provided hereunder at the point of delivery shall be three (3) phase,
sixty (60) hertz, and at system nominal voltages. 
 Article 5 
 EMC Resources 
 5.1 EMC Contract Resources (Commencement Date—December 31, 2010).

 5.1.1 Identification of Resources. Except as provided in Section 5.4.1, EMC’s Contract Resources during the period
commencing on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, shall consist of EMC’s entitlement to electric capacity and energy under the PPA and such additional
generation or purchased power resources or entitlements as EMC may acquire pursuant to Sections 5.1.3, 5.1.4 and 5.1.5. The FFR Resource is listed in Attachment 4-1. Except as provided in this Section 5.1.1, EMC shall not,
without first obtaining Duke’s prior written consent, enter into any other contracts for, or acquire any ownership interest in or contractual entitlement to, any additional electric generating resources or electric capacity or energy under
which electric capacity and energy would be used to serve EMC’s Native Load during the Term. 
 5.1.2 Changes to FFR Resources.
During the period commencing on the Commencement Date, and continuing through December 31, 2010, or any part thereof in which this Agreement is in effect, EMC shall not: (a) take any action that would materially affect the quantity or
quality of MSCG’s service obligations under the PPA without first obtaining Duke’s prior written consent, or (b) agree to any modification to provisions of the PPA, the WPSA, or the SEPA Contract that would increase or decrease
EMC’s entitlement to electric capacity or energy under such agreements and for which EMC’s consent is required (except as provided in Section 5.1.4) without first obtaining Duke’s consent to such modification. 
 5.1.3 Resource Impairment. In the event that all or a portion of the FFR Resource, or any other EMC Contract Resource, is terminated or becomes
permanently impaired, EMC shall acquire, at EMC’s expense, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent size and comparable
reliability to the EMC Contract Resource, or portion thereof, that such substitute is replacing. 
 5.1.4 New Catawba Resource. In the
event that NCEMC acquires all or part of Saluda River Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with such entitlement being made
available throughout the Year to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the entitlement so acquired by EMC. Upon Duke’s request,
EMC shall provide evidence reasonably satisfactory to Duke demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric system generating reserves. Duke shall limit 
  

 39 

 such requests to one (1) request per Year; provided, that if Duke reasonably believes that the sufficiency or
reliability of the electric system generating reserves backing EMC’s entitlement in the Catawba Nuclear Station may have changed since Duke’s last such request, this limitation shall not apply. In the event that EMC fails to demonstrate
that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s Generation Planning
Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined under the prior sentence) supplied by Duke to EMC at the then-applicable Monthly Demand Charge. Duke’s provision and
EMC’s purchase of such reserves shall not affect the determination of EMC’s Base Obligation. This Monthly charge shall be billed by Duke in accordance with the provisions of Article 13. 
 5.1.4.1 In the event that NCEMC purchases electric capacity and energy from Duke in lieu of NCEMC’s acquisition of all or a part of Saluda River
Electric Cooperative’s existing ownership interest in the Catawba Nuclear Station as provided in Section 5.1.4, and NCEMC sells, allocates or transfers a portion of such electric capacity and energy to EMC (through a modification of the
WPSA or pursuant to a new contract), EMC’s Base Obligation shall be increased by an amount equal to the amount of the electric capacity and energy so acquired by EMC. 
 5.1.5 Non-Consent Modification of EMC’s Contract Resources. In the event that EMC’s entitlements to electric capacity and energy
are reduced in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3, and 2.4 of the SEPA Contract, the amount of the EMC’s Base Obligation shall not be affected and the provisions of
Section 4.2.4.2 shall apply, except that if the Parties are unable to reach agreement as to the rates, terms and conditions under which Duke would sell electric capacity and energy to EMC, the provisions of Section 5.1.3 shall apply. EMC
shall provide written notice to Duke as soon as reasonably practicable after EMC becomes aware of any modification to EMC’s entitlement to electric capacity and energy under the WPSA or SEPA Contract pursuant to this Section 5.1.5. In the
event that EMC’s entitlements to electric capacity and energy are increased in accordance with Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3, 2.4 and 2.8 of the SEPA Contract, then, prior to the effective date
of such increase, EMC may elect either to (a) increase EMC’s Base Obligation by the same amount and to the same extent as EMC’s entitlements to electric capacity and energy are increased, or (b) make arrangements for the sale of
EMC’s entitlements to such electric capacity and energy to a third party or to Duke. If EMC fails to complete the arrangements described in (b) of the preceding sentence by the effective date of the increase in entitlements, then, as of
the effective date of the increase in entitlements, the EMC’s Base Obligation automatically will be increased as described in (a) of the preceding sentence. 
 5.2 EMC Contract Resources (January 1, 2011 - Termination of Agreement). 
 5.2.1 Identification of
Contract Resources. Except as provided in Section 5.4.1, EMC’s Contract Resources during the period January 1, 2011, through the termination of this Agreement shall consist of EMC’s entitlements to electric capacity and
energy under the contracts listed in Attachment 4-3 and such additional generation or purchased power resources or entitlements as EMC may acquire pursuant to Sections 5.2.3, 5.2.4, and 5.2.5. EMC’s entitlements under the contracts
that are listed in Attachment 4-3 shall be referred to as the Partial Requirements 
  

 40 

 Resources. Partial Requirements Resources consist of two (2) categories of entitlements: Baseload Resources and
Combined Cycle Resources. The amount and the material cost and operational terms and conditions of the Baseload Resources and Combined Cycle Resources shall be as set forth in Attachment 4-3, subject to modification in accordance with
Sections 5.2.3 and 5.2.4. Except as provided in this Section 5.2.1, EMC shall not, without first obtaining Duke’s prior written consent, enter into any other contracts for, or acquire any ownership interest in or contractual
entitlement to, any additional electric generating resources or electric capacity or energy under which electric capacity and energy would be used to serve EMC’s Native Load during the Term. 
 5.2.1.1 Extension of WPSA and SEPA Contract. Consistent with the provisions of Section 5.2.2, EMC shall have the right, without the prior
consent of Duke, to extend the term of the WPSA or the SEPA Contract under substantially the same terms and conditions as exist at the time that EMC seeks to extend the term of the WPSA or the SEPA Contract. If EMC extends the term of the WPSA or
the SEPA Contract in accordance with this Section 5.2.1.1, the EMC Contract Resources listed in Attachment 4-3 shall be deemed to be changed accordingly. 
 5.2.2 Changes To Partial Requirements Resources. Commencing January 1, 2011, through the termination of this Agreement, EMC shall not (a) take any action that would materially affect the quantity or
quality of EMC’s entitlement to electric capacity and energy from the Partial Requirements Resources without first obtaining Duke’s prior written consent, or (b) agree to any modification to provisions of the WPSA or the SEPA Contract
that would increase or decrease EMC’s entitlement to electric capacity or energy under such agreements and for which EMC’s consent is required (except as provided in Section 5.2.4) without first obtaining Duke’s consent to such
modification. 
 5.2.2.1 Modifications Effective After Termination. Notwithstanding the provisions of Section 5.2.2, EMC shall be
permitted to agree to any resource modification under the WPSA or the SEPA Contract without obtaining Duke’s consent to the extent that such resource modification will become effective after the Term; provided, that if such resource
modification will become effective prior to the end of the Term, EMC’s Partial Requirements Resources and Duke’s obligation to provide Partial Requirements Service shall not be modified prior to the date that this Agreement is terminated
unless Duke consents to such modification. 
 5.2.2.2 Sufficiency of Reserves. Upon Duke’s request, EMC shall provide evidence
reasonably satisfactory to Duke demonstrating that each of EMC’s Partial Requirements Resources is backed by sufficient and reliable electric system generating reserves. Duke shall limit such requests to one (1) request per Year with
respect to any Partial Requirements Resource; provided, that if Duke reasonably believes that the sufficiency or reliability of the electric system reserves backing any Partial Requirements Resource may have changed since Duke’s last such
request, this limitation shall not apply with respect to that Partial Requirements Resource. In the event that EMC fails to demonstrate that its entitlement in a Partial Requirements Resource is backed by sufficient and reliable generating reserves,
Duke shall supply, and EMC shall purchase, such reserves in an amount equal to that required under Duke’s Generation Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined
under the prior sentence) supplied by 
  

 41 

 Duke to EMC and the then applicable Monthly Demand Charge. This Monthly charge shall be billed by Duke in accordance with
the provisions of Article 13. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of the amount of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. EMC shall provide
written notice to Duke as soon as reasonably practicable after EMC becomes aware of a material change to the seller’s service obligations under the contracts listed in Attachment 4-3; provided, that such notice shall be for information
purposes only, and shall not affect any other obligations of either Party under this Agreement. 
 5.2.3 Non-Consent Partial Requirements
Resource Modifications. In the event that EMC’s entitlements are modified pursuant to Section 2.9(b) or Section 2.9(c) of the WPSA or Sections 2.2, 2.3, 2.4 and 2.8 of the SEPA Contract, EMC’s Partial Requirements
Resources shall be modified in the same amount and to the same extent. To the extent that a Partial Requirements Resource is modified pursuant to this Section 5.2.3, and the modification changes EMC’s entitlement in a resource listed as a
Baseload Resource in Attachment 4-3, the amount of such Baseload Resource, as listed in Attachment 4-3, shall be deemed to be changed accordingly. EMC shall provide written notice to Duke as soon as reasonably practicable after EMC
becomes aware of any modification to EMC’s entitlement to electric capacity and energy under the WPSA or SEPA Contract pursuant to this Section 5.2.3. To the extent that a Partial Requirements Resource is modified pursuant to this
Section 5.2.3, and the modification changes EMC’s entitlement in a resource listed as a Combined Cycle Resource in Attachment 4-3, the amount of such Combined Cycle Resource, as listed in Attachment 4-3, shall be deemed to be
changed accordingly. 
 5.2.4 New Catawba Resource. In the event that NCEMC acquires all or part of Saluda River Electric
Cooperative’s existing ownership interest in the Catawba Nuclear Station, and sells, allocates or transfers a percentage of that entitlement with such entitlement being made available throughout the Year to EMC (through modification of the WPSA
or pursuant to a new contract), the entitlement or resource so acquired by EMC shall constitute an additional Partial Requirements Resource, and shall be deemed to be an additional Baseload Resource. Upon Duke’s request, EMC shall provide
evidence reasonably satisfactory to Duke demonstrating that such entitlement in the Catawba Nuclear Station is backed by sufficient and reliable electric system generating reserves. Duke shall limit such requests to one (1) request per year;
provided, that if Duke reasonably believes that the sufficiency or reliability of the electric system generating reserves backing EMC’s entitlement in the Catawba Nuclear Station may have changed since Duke’s last such request, this
limitation shall not apply. In the event that EMC fails to demonstrate that its entitlement in the Catawba Nuclear Station is backed by sufficient and reliable generating reserves, Duke shall supply, and EMC shall purchase, such reserves in an
amount equal to that required under Duke’s Generation Planning Practices. The Monthly charge for such reserves shall be equal to the product of the amount of reserves (as determined under the prior sentence) supplied by Duke to EMC and the
then-applicable Monthly Demand Charge. This Monthly charge shall be billed by Duke in accordance with the provisions of Article 13. Duke’s provision and EMC’s purchase of such reserves shall not affect the determination of the amount
of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. 
 5.2.4.1 In the event that NCEMC purchases electric
capacity and energy from Duke in lieu of NCEMC’s acquisition of all or a part of Saluda River Electric Cooperative’s 
  

 42 

 existing ownership interest in the Catawba Nuclear Station as provided in Section 5.2.4, and NCEMC sells, allocates
or transfers a portion of such capacity and energy to EMC (through a modification of the WPSA or pursuant to a new contract), EMC’s Baseload Resources shall be increased by an amount equal to the amount of the electric capacity and energy so
acquired by EMC. 
 5.2.5 Resource Impairment. In the event that all or a portion of an EMC Contract Resource is terminated or becomes
permanently impaired, EMC shall acquire, at EMC’s cost, a substitute resource (backed by reserves in an amount equal to that required under Duke’s Generation Planning Practices) that is of substantially equivalent size and comparable
reliability to the EMC Contract Resource, or portion thereof, that such substitute resource is replacing, and that Duke reasonably agrees is sufficiently reliable. EMC’s acquisition of such substitute resource shall not affect the determination
of the amount of Partial Requirements Resources, Baseload Resources or Combined Cycle Resources. 
 5.3 No Duke Obligation for Customer Resources.
Unless otherwise explicitly provided in this Agreement, nothing herein shall be interpreted or construed as imposing upon Duke any obligations or liabilities, or for transferring to Duke any EMC obligations or liabilities, under or otherwise
pertaining to any EMC Contract Resource, nor shall anything in this Agreement be interpreted or construed as creating or implying any contractual or other relationship between Duke and any other party as to a EMC Contract Resource. 
 5.4 New Customer Resources. Except as provided in Section 5.4.1, Duke shall have no obligation to amend this Agreement and EMC shall not make an application
to FERC requesting that FERC require that any amendment be made to this Agreement, to accommodate any contractual entitlement to and/or ownership interest in or pertaining to any new electric capacity and/or energy resource that EMC may obtain after
the Effective Date. 
 5.4.1 PURPA Resources. Nothing herein shall limit EMC’s right to purchase electric capacity and energy
from a Qualifying Facility or other renewable resources pursuant to PURPA (“PURPA Resource”). If, during the Term, EMC purchases electric capacity and energy from a PURPA Resource with a nameplate capacity equal to or greater than one
(1) MW, then, for each Month during the period of such purchase: (i) the average hourly integrated electric energy delivered to EMC by such PURPA Resource during the Hours used for determination of the EMC Monthly Demand Quantity
determined in accordance with Section 7.1.4.1 or used for determination of the Monthly Billing Demand determined in accordance with Section 7.2.2.2 or Section 7.3.2.2, increased for losses between the point of measurement of
EMC’s Native Load and the Duke generation level, shall be added to the EMC Monthly Demand Quantity determined in accordance with Section 7.1.4.1 or to the Monthly Billing Demand determined in accordance with Section 7.2.2.2 or
Section 7.3.2.2 for such Month, as applicable; (ii) for purposes of calculating the electric energy charges under Sections 7.1.5, 7.2.3 and 7.3.3, as applicable, the amount of electric energy provided to EMC by such PURPA Resource during
an Hour, increased for losses between the point of measurement of EMC’s Native Load and the Duke generation level, shall be added to EMC’s Native Load and to the EMC Group Native Load for such Hour; and (iii) Duke shall credit EMC, on
a Monthly basis, an amount equal to the electric capacity and energy credits to which EMC would be entitled as set forth in Duke’s NCUC retail electric tariff Schedule PP-H or Schedule PP-N (as applicable), Interconnected to Distribution System
or 
  

 43 

 Transmission System (as applicable), or its successor tariff, if the electric capacity and electric energy provided to
EMC by such PURPA Resource were provided to Duke pursuant to and in accordance with such schedules. The interconnection to Duke’s (rather than the EMC’s) Distribution System or Transmission System, as those terms are defined in the
schedules, will determine whether the Distribution System or Transmission System rates apply. EMC will coordinate with Duke to determine the proper application of these schedules. If Schedule PP-H or Schedule PP-N do not apply to the PURPA Resource,
then Duke shall credit EMC, on a Monthly basis, an amount equal to the electric capacity and energy credits to which EMC would be entitled under PURPA if the electric capacity and electric energy provided to EMC by such PURPA Resource were provided
to Duke pursuant to PURPA. EMC’s purchase of the electric capacity and energy from a PURPA Resource shall not affect the determination of the Annual Capacity Quantity determined in accordance with Sections 3.5.2.3.1, 3.5.2.3.2 or
3.5.2.3.3, as applicable. 
 Article 6 
 Priority of Service 
 6.1 Interruption of FFR Supplemental Service and Partial Requirements Service. FFR
Supplemental Service and Partial Requirements Service shall have an interruption priority equivalent to Duke’s Native Load. It is expressly understood and agreed that, except for Duke’s failure to comply with Section 6.2 or as
provided in Section 6.4, Duke shall not be liable to EMC for damages resulting from any such interruptions or impairment of FFR Supplemental Service or Partial Requirements Service. Duke shall use Commercially Reasonable Efforts to notify EMC
by telephone of any scheduled interruption or scheduled impairment of service hereunder and shall use Commercially Reasonable Efforts to confirm such notice by facsimile, electronic mail, or letter on the same date such notice was given. Duke shall
notify EMC by telephone of any unscheduled interruption or impairment of service hereunder as soon as reasonably practicable under the circumstances resulting in such unscheduled interruption or impairment of service. Duke shall use Commercially
Reasonable Efforts to remove all causes of such interrupted or impaired service hereunder. 
 6.2 Curtailments of Load. Except as provided in
Section 4.2.6, EMC’s Native Load shall be subject to curtailment only in accordance with this Section 6.2. In the event that Duke curtails Duke Native Load for any reason, including Force Majeure, EMC shall curtail its load as
directed by Duke. Except as provided in Section 4.2.6, Duke shall not adversely distinguish against EMC’s Native Load in curtailing Duke’s Native Load and directing EMC to curtail EMC’s Native Load; provided, however, that Duke
has sole responsibility to design all curtailments, and may order any manner of curtailment that Duke believes is appropriate so long as EMC’s Native Load and Duke’s Native Load present in the electrical area being curtailed are curtailed
on a non-discriminatory basis. In permitting EMC to restore EMC’s Native Load and restoring Duke’s Native Load that was curtailed, Duke shall not adversely distinguish against EMC’s Native Load, except as provided in
Section 4.2.6. The load curtailment and restoration provisions set forth in this Section 6.2 are in addition to, and without limitation of, the load curtailment and restoration provisions set forth in Section 4.2.6. 
  

 44 

 6.3 Emergency Load Curtailment Program. EMC agrees to implement an emergency load curtailment program for the
curtailment of EMC’s Native Load in the event a load curtailment order is made by Duke. EMC shall comply with its obligation to implement and maintain an emergency load curtailment program and to curtail EMC’s Native Load in the manner
specified by Section 6.2. 
 6.4 Substitute Energy. In the event that Duke fails to deliver a sufficient quantity of electric energy to meet its
obligations to provide FFR Supplemental Service or Partial Requirements Service, as the case may be, and Duke’s failure to deliver such electric energy is not pursuant to a curtailment permitted under Section 4.2.6 or 6.2 of this
Agreement, or is otherwise excused under this Agreement, Duke shall pay to EMC an amount equal to EMC’s Cover Costs, if any, incurred for the electric energy that EMC obtained to replace such electric energy (“Substitute Energy”) Duke
failed to supply. EMC’s Cover Costs shall be equal to Substitute Energy Costs incurred by EMC for the Substitute Energy minus the costs that EMC would have incurred had Duke supplied the electric energy to EMC. EMC shall bill its Cover Costs to
Duke in accordance with the provisions of Article 13. In the event that EMC incurs Cover Costs for Substitute Energy over a period that extends past the Month in which Duke’s failure to deliver electric energy occurs, then Duke shall pay
the Cover Costs incurred in the following Month(s) in accordance with the billing and payment provisions of Article 13. 
 6.5 Substitute Energy
Costs. Substitute Energy Costs shall be equal to (i) in the case in which EMC contracts with an energy supplier to provide Substitute Energy to EMC, the cost that EMC, acting in a commercially reasonable manner, incurs to purchase such
Substitute Energy, or (ii) in the case in which Substitute Energy is provided to EMC by the Control Area operator, system operator, or similar entity providing such service on behalf of load (or load serving entities), the cost to EMC imposed
on EMC by such Control Area operator, system operator, or other entity providing such Substitute Energy. In either case, Substitute Energy Costs shall include ancillary services charges, if any, reasonably incurred by EMC to the point where electric
energy is delivered to the Transmission System or imposed to the point where electric energy is delivered to the Transmission System by the Control Area operator, system operator, or other entity providing Substitute Energy, including congestion
charges, energy imbalance charges, backup capacity charges, replacement capacity charges, deficient capacity charges, commitment fees, ratcheted demand and similar charges incurred by EMC in obtaining such Substitute Energy.

 7.4 Monthly
Reserve Capacity Charges. In the event that Duke provides Replacement Energy to EMC pursuant to Section 4.2.4 in an amount of five thousand (5,000) kW or greater during any Hour of a Year, EMC shall pay a Monthly Reserve Capacity
Charge equal to the product of (i) the Monthly Demand Rate as calculated in Section 7.3.2.1 and (ii) the amount (in kW) of reserves that would be required under Duke’s Generation Planning Practices for a generating resource of a
size equivalent to the amount of Replacement Energy provided to EMC (the “Reserve Capacity Amount”). This charge shall commence on the Day following the Day on which Duke provided Replacement Energy to EMC, and shall terminate on
December 31 of that Year. For example, if Duke provides a maximum amount of 100,000 kWh of Replacement Energy to EMC in any given Hour on July 15, 2007, and the reserves that would be required for a 100,000 kW generating resource under
Duke’s Generation Planning Practices is 17,000 kW, EMC shall be responsible for a Monthly Reserve Capacity Charge for 17,000 kW from July 16, 
  

 53 

 2007, through December 31, 2007, subject to increase as provided in the next sentence. In the event that Duke
provides Replacement Energy to EMC for any additional Hours during such Year, and the amount of Replacement Energy provided during any such Hours is greater than that previously provided during the Year, then the Reserve Capacity Amount shall be
increased to reflect such greater amount of Replacement Energy, effective the Day after the Replacement Energy is provided. In the event that Duke provides Replacement Energy to EMC in a subsequent Year, the foregoing provisions shall apply, and EMC
shall pay Monthly Reserve Capacity Charges with respect to such Replacement Energy as provided above. Notwithstanding anything in this Section 7.4 to the contrary, the Monthly Reserve Capacity Charges shall terminate no later than
December 31, 2010. Any Monthly Reserve Capacity Charge, or increase in such charge, that begins on a Day other than the first Day of the Month shall be adjusted pro rata for that Month to reflect the number of Days during the Month in which the
charge or charge increase was in effect. 
 7.4.1 Force Majeure Events. Notwithstanding the provisions of Section 7.4, in the
event that Duke provides Replacement Energy to EMC due to the occurrence of a force majeure event, EMC shall not incur a Monthly Reserve Capacity Charge due to Duke’s provision of Replacement Energy for the first twenty-four (24) Hours
following such occurrence. For purposes of this Section 7.4.1, the term “force majeure” means an event or circumstance that: (i) prevents the party claiming to be affected by it from performing its obligations in whole or in
part; (ii) is not within the reasonable control of the claiming party, or the result of the negligence of the claiming party, and (iii) by the exercise of due diligence, the claiming party is unable to overcome in a commercially reasonable
manner, and, without limiting the scope of the definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or
actions or restraints by court order or governmental authority or arbitration award (so long as the claiming party has not sought or has opposed, to the extent reasonable, such actions or restraints). It is expressly acknowledged that transmission
service interruptions or curtailments imposed by a transmission provider in response to transmission capacity or availability shortages shall not be “force majeure” events or circumstances for purposes of this Section 7.4.1.

 7.5 Payment. All charges or payments contemplated by this Article 7 shall be made in accordance with provisions of Article 13.

 7.6 Determination of EMC Capacity and Energy Demands. For purposes of determining the electric capacity and energy charges under this Agreement,
EMC’s Native Load demands shall be as determined under the NOA (which demands shall include the adjustments under the NOA for losses between the point of delivery under the NITSA and the point of measurement, and the corrections under the NOA
for any metering failures or inaccuracies), and shall be increased by ( 1 / (1 - TLF ), in order to reflect such demands at the generation level (i.e., at the point at which power is available for transmission). Metered receipts used in
billings and accounting hereunder will in all cases include adjustments for such losses. TLF shall be equal to the transmission loss factor set forth in the Transmission Provider’s OATT, and shall be expressed as a decimal. For example, if the
transmission loss factor in the Transmission Provider’s OATT is three percent (3%), then ( 1 / (1 - TLF )) shall be equal to ( 1 / (1 -.03)), or ( 1 / .97 ). In the event that the NOA is terminated, or the electric capacity and energy demands
measured under the NOA no longer include an adjustment for losses between the point of delivery under the NITSA and the 
  

 54 

 point of measurement or provisions for correcting such demands for metering failures or inaccuracies, then, for purposes
of determining the capacity and energy charges under this Agreement, EMC’s metered electric capacity and energy demands shall be adjusted for losses between the point of delivery under the NITSA and point of measurement and further increased by
( 1 / (1-TLF)), in order to reflect such demands at the generation level (i.e., at the point at which power is available for transmission), and suitable arrangements shall be made by the Parties for correcting such demands due to
metering failures or inaccuracies.

 9.4.2 Congestion Costs. In the event that the Transmission Provider implements a pricing methodology that allocates congestion costs on a
locational basis, in determining the dispatch order of Duke’s Generation System, Duke shall make no adverse distinction between Duke’s Native Load and Duke’s obligations to supply FFR Supplemental Service or Partial Requirements
Service, as applicable under this Agreement. Duke further agrees that, in the event it designates Delivery Points for Duke’s Generation System, Duke shall make no adverse distinction between Duke’s Native Load and Duke’s obligations
to supply FFR Supplemental Service or Partial Requirements Service, as applicable under this Agreement. The Parties shall reasonably cooperate with each other in an effort to develop and implement congestion management strategies designed to
minimize the incurrence of congestions costs associated with the delivery of electric energy under this Agreement. Duke will provide EMC with recommended strategies to manage such congestion costs, under terms that would not subject Duke’s
Native Load to any costs that Duke would not otherwise incur, and if EMC agrees with such recommendation, Duke will use Commercially Reasonable Efforts to implement the recommended congestion management strategies. Duke shall also use Commercially
Reasonable Efforts to comply with the congestion management rules that may be adopted by the Transmission Provider.

 Article 10 
 Operating Committee 
 10.1 Operating Committee. The Parties shall establish an Operating Committee consisting
of one (1) Representative each. The Operating Committee shall act only by unanimous agreement or consent. Duke and EMC shall designate their respective Representatives to the Operating Committee, plus any alternate, by written notice delivered
in accordance with Section 16.22 within thirty (30) Days after the Effective Date. Each Party’s Representative on the Operating Committee is authorized to act on behalf of such Party with respect to any matter arising under this
Agreement. 
 10.2 Duties of the Operating Committee. The Operating Committee shall facilitate the coordination and interaction between the Parties
with respect to the performance of the duties and obligations imposed on the Parties hereunder, including development or revision of appropriate protocols and procedures therefor. The Operating Committee shall not, however, have any authority to
modify or otherwise alter the Parties’ rights and obligations under this Agreement. 
 Article 11 
 Demand Side Management 
 11.1 Availability of Demand
Side Management Resource Programs. EMC may make available to EMC’s Native Load customers EMC Demand Side Management Resource Programs to the same extent and under comparable terms and conditions as Duke’s Demand Side Management
Resource Programs; provided, however, that EMC may not make available to EMC’s Native Load customers any demand side management resource programs or similar programs other than such EMC Demand Side Management Resource Programs unless EMC is
otherwise required by RUS or by applicable Law to make other demand management side resource programs available to EMC’s Native Load customers or is otherwise permitted under Section 11.7. Except as set forth in Section 4.2.6, the
terms and conditions of EMC Demand Side Management Resource Programs shall be applied to EMC’s Native Load customers and enforced by Duke in the same or comparable manner as they are applied to Duke’s Native Load retail customers and
enforced by Duke. Except as set forth in Section 4.2.6, in implementing and operating such EMC Demand Side Management Resource Programs, Duke shall make no adverse distinction with respect to EMC’s Native Load. 
 11.2 Changes to Demand Side Management Resource Programs. Upon ninety (90) Days prior written notice, Duke shall advise EMC of any modifications, additions,
or deletions that have been or will be made to the Demand Side Management Resource Programs, and the EMC Demand Side Management Resource Programs available hereunder to EMC’s Native Load customers shall be deemed to have been revised to reflect
such modifications, additions, or deletions without any further action required by either Party. 
  

 60 

 11.3 Credits. Except for any EMC Demand Side Management Resource Program implemented pursuant to Section 11.7
of this Agreement, for each EMC Native Load customer that implements an EMC Demand Side Management Resource Program, EMC shall be entitled to a billing credit. Such billing credit shall be calculated in accordance with the credit applicable for the
Demand Side Management Resource Program, as specified in the rider approved and on file with NCUC for such Demand Side Management Resource Program. Each Month, Duke shall aggregate the total billing credits to which EMC is entitled pursuant to this
Section 11.3, and provide EMC a credit on the Monthly statement delivered in accordance with Section 13.2 equal to the total billing credits for such Month. 
 11.4 Necessary Arrangements. To the extent that an EMC Native Load customer agrees to implement an EMC Demand Side Management Resource Program, the Parties shall cooperate in preparing any detailed
implementation procedures and arrangements required to implement such program, provided that, except for any EMC Demand Side Management Resource Program implemented pursuant to Section 11.7 of this Agreement, Duke shall retain sole operational
control over such EMC Demand Side Management Resource Program implemented. The failure of the Parties to agree on detailed implementation procedures and obligations shall not affect Duke’s obligation to provide EMC with credits as determined by
Section 11.3. 
 11.4.1 Audits. For each EMC Demand Side Management Resource Program whose credit depends upon the number of EMC
Native Load customers, EMC shall be required to provide Duke written notice, by no later than January 31 of each Year, of the number of EMC Native Load customers with whom EMC has entered into arrangements pursuant to this Section 11.4 for
such EMC Demand Side Management Resource Program. Duke shall have the right periodically to perform audits, in accordance with the terms of Section 13.6 to verify the accuracy of the notices concerning the number of EMC Native Load customers
with whom EMC has entered into arrangements for each EMC Demand Side Management Resource Program. Based on the results of such audits, Duke shall be entitled, in accordance with the terms of Section 13.2.2 to revise or adjust the level of
credits that Duke previously had provided EMC. 
 11.5 Start-Up Conditions. No later than sixty (60) Days after the Effective Date, Duke shall
conduct a system-wide test of each EMC Demand Side Management Resource Program to determine its capability. Duke shall provide EMC with the results of such test no later than five (5) Business Days after the completion of the system-wide test.
Duke shall not be required to provide credits for EMC Demand Side Management Resource Programs unless the applicable standards and requirements specified for Duke’s Demand Side Resource Management Programs under the riders approved and on file
with the NCUC shall have been met, and the testing provided for in this Section 11.5 shall have been accomplished. 
 11.6 Periodic Testing. Duke
shall have the right periodically, but no less than once per Year, to conduct a system-wide test of each EMC Demand Side Management Resource Program to determine whether the tested EMC Demand Side Management Resource Program is capable of providing
a level of demand reduction equal to the level of the credit that EMC is, at the time of such system-wide test, receiving for such EMC Demand Side Management Resource Program. Subject to Section 11.6.1, if, at the time of such system-wide test,
one or more EMC Demand Side Management Resource Program(s) do not provide the level of demand reduction equal to the level of the credit that EMC is receiving for such EMC Demand Side Management Resource 
  

 61 

 Program(s), Duke shall have the right to (i) reduce the credit provided to EMC to the actual level of demand
reduction provided at the time of the system-wide test and, in accordance with the terms of Section 13.2.2, to revise or adjust the level of credits that Duke previously had provided EMC, and (ii) provide written notice within ninety
(90) Days of the system-wide test, to cancel such EMC Demand Side Management Resource Program(s). 
 11.6.1 Retesting. Within
sixty (60) Days of any failure of a system-wide test for an EMC Demand Side Management Resource Program, EMC shall have the right to have Duke conduct a retest in order to demonstrate that such EMC Demand Side Management Resource Program is
capable of providing the level of demand reduction equal to the level of the credit that EMC previously was receiving for such EMC Demand Side Management Resource Program. To the extent that any such system-wide retest demonstrates that the EMC
Demand Side Management Resource Program is capable of providing demand reduction, the credit provided to EMC shall be restored to the prior level or such lesser level as demonstrated by the result of such rescheduled test and, to the extent
applicable, Duke shall, in accordance with the terms of Section 13.2.2, revise or adjust the level of credits that Duke previously had provided EMC and any notice to terminate rendered by Duke pursuant to 11.6 shall be null and void.

 11.7 EMC Demand Side Management. If Duke’s Annual Planning Period shifts from the Summer Period to the Winter Period, then EMC shall have the
authority to implement and call upon EMC Demand Side Management Resource Programs to control EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the Winter
Period to the level equal to but not below the average of (i) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the immediately preceding
Summer Period and (ii) the average of EMC’s Native Load demands coincident with the twenty (20) highest Hourly (integrated sixty-minute) Duke Schedule 1 Demands during the second preceding Summer Period. For example, if (i) the
Annual Planning Period during May 2012 - April 2013 is the Summer Period (May 2012 - September 2012), and the average of EMC’s integrated sixty (60) minute EMC Native Load demands coincident with the twenty (20) highest Hourly Duke
Schedule 1 Demands during such period is 100 MWs; and (ii) the Annual Planning Period during May 2013 - April 2014 is the Winter Period (October 2013 - April 2014), and the average of EMC’s integrated sixty (60) minute EMC Native Load
demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during the Summer Period immediately preceding such Winter Period (i.e., May 2013 - September 2013) is 102 MWs; then EMC may call upon EMC Demand Side Management
Resource Programs to control EMC’s integrated sixty (60) minute EMC Native Loads demands coincident with the twenty (20) highest Hourly Duke Schedule 1 Demands during October 2013 - April 2014 to the level equal to but not below
101 MWs. It is expressly acknowledged that (a) Duke shall also have the right to call upon any available EMC Demand Side Management Resource Program implemented pursuant to this Section 11.7, and (b) EMC shall not be entitled to a
billing credit under Section 11.3 (or any other provision of this Agreement) in connection with any EMC Demand Side Management Resource Program implemented pursuant to this Section 11.7. 
  

 62 

 Article 12 
 Modification of This Agreement 
 12.1 Unilateral Modification. Except as provided in Section 12.3:

 No unilateral modification, amendment or other change to the terms of this Agreement shall be permitted or deemed effective for any reason,
and the rates, terms and conditions specified herein shall not be subject to change through application to FERC pursuant to the provisions of Sections 205 or 206 of the Federal Power Act absent the written agreement of both Parties. Any
amendment or modification to this Agreement shall be deemed enforceable if and only if such amendment or modification (a) has been reduced to writing, (b) has been agreed to and duly executed by both Parties in writing, and (c) has
received all requisite approvals of Governmental Authorities necessary for the effectiveness thereof. Each Party hereby irrevocably waives its rights, including any rights under Sections 205 and/or 206 of the Federal Power Act, to file a
complaint, request an investigation, or make any unilateral rate-change request seeking: (a) an order from FERC finding that any rate or provision in this Agreement is unjust or unreasonable; (b) any refund with respect to this
Agreement’s rates; or (c) any other unilateral modification to this Agreement. Each Party agrees not to make any such unilateral filing or request, and agrees and warrants that these covenants and waivers shall be binding notwithstanding
any regulatory, market, or other change that may occur at any time during the Term. 
 12.2 Mobile-Sierra Public Interest Standard. Except as
provided in Section 12.3, to the extent this Agreement is challenged by any person or its terms are subjected to review under the Federal Power Act or other Laws, the “just and reasonable” standard shall not apply. Instead, absent the
agreement of both Parties to the proposed change, and except as provided in Section 12.3, the standard of review for changes to this Agreement proposed by a Party, a non-party, or FERC acting sua sponte shall be the “public
interest” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956); Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956). 
 12.3 Changes To Certain Charge Components. Notwithstanding anything else herein to the contrary, nothing contained herein shall be construed as affecting in any
way the right of either Party to unilaterally make application to FERC under Sections 205 or 206 of the Federal Power Act (i) to change the depreciation rates and nuclear decommissioning accrual used in Schedule 1, (ii) to
include additional cost items that are incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable, to EMC that are not included in Schedule 1, (iii) to exclude from Schedule 1 cost items
that are no longer incurred in providing FFR Supplemental Service or Partial Requirements Service, as applicable to EMC, or (iv) to change Schedule 1 to reflect changes in Duke’s accounting consistent with the Accounting
Requirements (including the addition of new accounts and the removal of obsolete accounts). In addition, in the event that (a) EMC implements new time-of-use rates or materially modifies its existing time-of-use rates, for some or all of
EMC’s Native Load customers, (b) such rates result in a reduction of EMC’s Monthly Billing Demand under Sections 7.2.2.2 or 7.3.2.2, and (c) such Monthly Billing Demand reduction does not result in a commensurate reduction
in the EMC demands that Duke utilizes in Duke’s Generation Planning Practices, Duke may make unilateral application to FERC 
  

 63 

 under Section 205 of the Federal Power Act to change the calculation of the Monthly Billing Demand set forth in
Sections 7.2.2.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. In the event that Duke makes such a filing with FERC, EMC may oppose such filing, and, in addition, shall be free to
propose any other method for calculating the Monthly Billing Demands set forth in Sections 7.2.2.2 or 7.3.2.2 to more appropriately reflect the costs that Duke incurs in providing service under this Agreement. 
 12.4 Standard of Review for Permitted Changes. The Parties acknowledge that, as of the Effective Date, FERC has issued a proposed rule that, if adopted, would
specify the language for parties to include in future agreements where the parties intend that the “just and reasonable” standard of review apply to amendments to the agreements. Notwithstanding the language that ultimately may be adopted
by FERC, it is the intent of the Parties that the standard of review that FERC shall apply when acting on proposed modifications to this Agreement that are permitted under Section 12.3, either on FERC’s own motion or on behalf of a
signatory or non-signatory, shall be the “just and reasonable” standard of review rather than the “public interest” standard of review. 
 12.5 Scope of Waiver. Nothing in this Article 12 shall be construed to modify or limit any Party’s right to enforce the express terms of this Agreement as they are written in this Agreement. 
 Article 13  
 Billing and
Payment 
 13.1 Billing Period. Unless otherwise specifically agreed upon by the Parties in the terms of this Agreement or otherwise in writing,
the Month shall be the standard period for determining all billings and payments under this Agreement. 
  

	13.2	Billing Statements. 

 13.2.1 Initial
Statements. After the end of each Billing Period, Duke shall deliver to EMC a statement setting forth for the Billing Period (i) the sum of the electric energy delivered and/or received for all Hours during that Billing Period, and
(ii) Duke’s calculation of any amounts due from EMC under this Agreement for the Billing Period. In addition, in the event that there are amounts due from Duke to EMC under this Agreement for a Billing Period, EMC shall deliver to Duke,
after the end of such Billing Period, a statement setting forth for the Billing Period EMC’s calculation of any amounts due from Duke under this Agreement for the Billing Period. Notwithstanding the foregoing, a Party’s failure to render a
statement as set forth above shall not relieve the other Party from its obligation to make payment to the billing Party when such statement is rendered, provided such statement is rendered within one (1) year after the end of the Billing
Period. 
 13.2.2 Subsequent Payment Adjustments. The Parties understand that in certain cases Monthly billings will need to be made
on an estimated basis. In addition, the Parties understand that after-the-fact adjustments to amounts owed or revenues received may be made in order to reflect correctly the amounts payable by one Party to the other under this Agreement. Each Party

  

 64 

 shall cooperate in good faith with the other Party to obtain the requisite information and perform the necessary
computations so as to true-up or otherwise adjust any estimated or adjusted billings promptly. 
 13.3 Timeliness of Payment. Unless otherwise agreed
by the Parties, all statements rendered under this Agreement, whether by Duke or EMC, shall be due and payable in accordance with each Party’s statement instructions on or before the later of the twentieth (20th) Day of each Month, or the tenth (10th) Day after receipt of the statement or; if such Day is not a Business Day, then on the next Business Day. Each Party shall make payments in immediately available funds by electronic funds
transfer, or by other mutually agreeable method, to the account designated in writing by the other Party. Any non-disputed amounts (other than amounts for which payment may be withheld pursuant to Section 13.5) not paid by the due date shall be
deemed delinquent and shall accrue interest at the Interest Rate, such interest to be calculated from and including the due date to but excluding the date the delinquent amount is paid in full. 
 13.4 Netting of Payments. The Parties hereby agree that they shall discharge mutual debts and payment obligations due and owing to each other on the same date
through netting, in which case all amounts owed by each Party to the other Party under this Agreement during the Billing Period, including any related interest, payments, and credits, shall be netted so that only the excess amount remaining shall be
paid by the Party who owes it. If no mutual debts or payment obligations exist and only one Party owes a debt or obligation to the other Party during the Monthly Billing Period, including but not limited to any interest, payments, or credits, that
Party shall pay such sum in full when due. 
 13.5 Disputes and Adjustments of Statements. A Party may, in good faith, dispute the correctness of any
statement or any adjustment to a statement, rendered under this Agreement or adjust any statement for any arithmetic or computational error within twenty-four (24) Months of the date the statement, or adjustment to a statement, was rendered. If
a statement or portion thereof, or any other claim or adjustment arising under this Agreement is disputed, the disputing Party shall provide written notice to the other Party (the “Billing Dispute Notice”) which (a) states the good
faith basis for the dispute, (b) specifies the amount in dispute (the “Disputed Amount”), if any, and (c) provides documentation reasonably supporting the determination of the Disputed Amount. The disputing Party shall, at its
option, (a) make payment to the other Party of the Disputed Amount under protest and thereafter shall be reimbursed by the other Party for any amount determined to be refundable after the resolution of such dispute or (b) withhold one half
(1/2) of the Disputed Amount and make payment to the other Party of the other one half (1/2) of the Disputed Amount. Payment to the other Party of one half (1/2) of the Disputed Amount shall not relieve the disputing Party of the
obligation to pay interest accrued at the Interest Rate from and including the date such payment was due to but excluding the date of such payment of any portion of such Disputed Amount withheld and determined to be due and payable after the
resolution of such dispute. Likewise, the other Party shall not be relieved of the obligation to pay interest accrued at the Interest Rate from and including the date such payment was made to but excluding the date of reimbursement of any portion of
such Disputed Amount paid and determined to be refundable after the resolution of such dispute. 
 In the event that a Party, by timely
notice to the other Party, disputes the correctness of a statement or portion thereof or any other claim or adjustment arising under this Agreement, the 
  

 65 

 other Party shall promptly review the disputed statement or adjustment and shall notify the disputing Party, within
forty-five (45) Days following receipt of the Billing Dispute Notice, of the amount of any error or the amount of any payment or reimbursement that the disputing Party is required to make or is entitled to receive. Payments determined to be due
by the disputing Party shall be included on the next Monthly statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date paid. Reimbursements determined to be due from the other Party
shall be included on the next Monthly statement, and shall include interest accrued at the Interest Rate from and including the due date to but excluding the date reimbursed. If the disputing Party disagrees with the other Party’s resolution of
any dispute, then the Parties shall submit the dispute for resolution in accordance with Article 14. 
 Inadvertent overpayments shall
be returned upon request or deducted by the Party receiving such overpayment from subsequent payments, with interest accrued at the Interest Rate from and including the date of such overpayment to but excluding the date repaid or deducted by the
Party receiving such overpayment. Any dispute with respect to a statement is waived unless the other Party is notified in accordance with this Section 13.5 within twenty-four (24) Months after the statement is rendered or any adjustment to
the statement is made. Neither Party shall have the right to challenge any statement, to invoke arbitration of the same or to bring any court or administrative action of any kind questioning the propriety or any other aspect of such statement after
a period of twenty-four (24) Months from the date the statement was rendered; provided, however, that in the case of a statement containing estimates, such twenty-four (24) Month period shall run from the date the statement is adjusted to
reflect the actual amounts due. 
 13.6 Records and Audits. Each Party shall keep such records and documents as may be needed to afford a clear and
complete history of all transactions under this Agreement, and the cost information used to calculate the charges for such transactions, for twenty-four (24) Months following the Month in which such transaction occurs. In addition, during such
twenty-four (24) Month period, EMC shall have the right to audit all records, including phone and computer records, related to Duke’s performance of its obligation not to adversely distinguish against EMC’s Native Load under
Section 4.3.3, Section 6.2, and Section 9.4.2 of this Agreement. If a Party initiates an audit through a notice to the other Party within the time period provided herein, the records and documents related to such audit are required to
be maintained under this Section 13.6, then the other Party will retain such records and documents until such audit is complete. If a Party issues an Original Notice pursuant to Article 14, then the Parties will retain the records and documents
relating to such dispute until the resolution of such dispute. In maintaining such records and documents, EMC and Duke may rely upon the logs and other meter information routinely recorded by Transmission Providers or utilities responsible for
coordination of the purchases and sales. During such twenty-four (24) Month period, either Party, or any third party Representatives of such Party, shall have the right, at its sole expense and during normal working Hours, to examine the
records of the other Party, including documents and records held by third parties, to the extent reasonably necessary to verify the accuracy of any statement, charge, or computation made pursuant to this Agreement. The Party requesting the audit
shall pay the costs associated with any independent auditor. Upon the request of the auditing Party, the document custodian of the other Party shall certify to the auditing Party that, to the best of such person’s knowledge after reasonable
investigation, the documents and records supplied are true and complete and, in the case of copies, are true, complete and correct copies of the original documents requested by the auditing Party. 
  

 66 

 13.6.1 Procedures. EMC may make a written request for Duke to provide access to documents and
records to verify the accuracy of any statement, charge or computation made pursuant to this Agreement. Within ten (10) Business Days of the receipt of a written request from EMC, Duke shall either provide EMC, or its Representative, with
access to the documents and records which are the subject of the written request or provide EMC with copies of the original documents and records. If Duke elects to provide EMC, or its Representative, with access to the documents and records
requested by EMC, EMC or its Representative shall be permitted to make, at its own expense, copies of the documents and records to which it or its’ Representative has been provided access. Any copies made by EMC or its Representative shall be
subject to the confidentiality provisions set forth in Section 16.6. If Duke is unable to provide EMC with access or copies within ten (10) Business Days of the receipt of EMC’s written request because it is unable to locate or gain
access to such documents and records after reasonable investigation, Duke shall, within ten (10) Business Days of the receipt of such written request, provide EMC with notice describing the reasons for its failure to provide access to or copies
of the documents and records, its efforts to obtain such documents and records, and its best estimate of the time in which EMC will be permitted access to or provided copies of such documents and records. The twenty-four (24) Month period
provided for in Section 13.5 shall be tolled from the date Duke gives notice describing the reasons for its failure to provide access to or copies of the documents and records until Duke shall have (i) provided EMC with copies or access to
all documents and records specified in EMC’s written request or (ii) Duke’s document custodian shall have certified, that to the best of his knowledge after reasonable investigation that such document does not exist or Duke cannot
locate or produce such document or records. 
 13.6.2 Adjustments Resulting from Audits. If any audit or examination under this
Section 13.6 reveals any inaccuracy in any statement, the necessary adjustments in such statement and the payments thereof shall be made promptly and shall accrue interest at the Interest Rate from the date the overpayment or underpayment was
made until paid; provided, however, that no adjustment for any statement or payment shall be made unless objection to the accuracy thereof was made prior to the lapse of twenty-four (24) Months from the rendition thereof, and thereafter any
objection shall be deemed waived. 
 13.6.3 Confidentiality. The auditing Party shall keep confidential any information obtained in
the audit. If requested, a Party shall provide to the other Party statements evidencing the quantity of electric energy provided under this Agreement for up to the prior twenty-four (24) Months. If an audit is requested with respect to any
records held by the a Party or a third party and those records cannot be disclosed to the requesting Party as a result of a confidentiality obligation, then to the extent legally permissible, the auditing Party shall select an independent auditor to
perform the audit consistent with the Parties’ rights under this Agreement and with such confidentiality arrangements as may be required by the confidentiality obligation in question. 
  

 67 

 Article 14  
 Dispute Resolution 
 14.1 Arbitration. Except as otherwise provided below, any dispute arising out of or in
connection with this Agreement or its performance that cannot be resolved after good faith discussions and negotiations between the Parties as set forth in Section 14.2 shall be submitted to binding arbitration. A dispute with respect to
whether a Material Adverse Ruling meets the materiality standard specified in Section 2.3.2.2(c)(1) or (c)(2) shall be subject to dispute resolution pursuant to Section 2.3.2.2.2. A dispute with respect to an invoice shall first be subject
to the procedures set forth in Section 13.5, and if such dispute is not resolved in accordance with such procedures, then such dispute shall be submitted to binding arbitration in accordance with this Article 14. Any arbitration commenced
under this Article 14 shall be conducted in accordance with the North Carolina Arbitration Act, N.C.G.S. Section 1-567 et seq., and the non-administered arbitration rules and procedures of the CPR Institute for Dispute Resolution
(“CPR”) in effect at the time arbitration is commenced, except where specifically modified by this Agreement. 
 14.2 Negotiation and Notice of
Arbitration. Prior to initiating arbitration hereunder, a Party shall provide the other Party with written notice of the dispute, a proposed means for resolving the same, and support for the Party’s position (“Original Notice”).
Thereafter, Representatives of the Parties shall meet in person to discuss the matter and attempt in good faith to reach a negotiated resolution of the dispute. The Parties agree to provide and exchange supporting facts, records and information
regarding the dispute (including calculation and bases) as part of the good faith negotiations. If the Parties have not agreed upon a resolution of the dispute within thirty (30) Days after the provision of the Original Notice or such other
time period as the Parties may agree in writing to allow for discussions and negotiation (“Negotiation Period”), then at any time after the end of the Negotiation Period, a Party may provide written notice to the other declaring an impasse
(“Impasse Notice”) and initiating binding arbitration in accordance with the further provisions of this Article 14. A Party providing an Impasse Notice shall also contemporaneously notify all entities within the EMC Group of the
provision of its Impasse Notice. 
 14.3 Individual, Joint or Consolidated Arbitration. If, within thirty (30) Business Days of EMC’s
provision of an Impasse Notice, Piedmont and/or Rutherford also provides an Impasse Notice relating to substantially the same issue as raised by EMC’s Impasse Notice, or if Duke contemporaneously provides each of EMC, Piedmont and/or Rutherford
an Impasse Notice relating to substantially the same issue, then each entity within the EMC Group shall have ten (10) Business Days following the expiration of such thirty (30) Business Day period to provide written notification to Duke
stating whether or not such entity will voluntarily proceed in a joint or combined arbitration. 
 If EMC and one or more of the entities
within the EMC Group that have provided or received Impasse Notices within the specified time period relating to substantially the same issue elect to proceed individually or in more than one arbitration proceeding, Duke shall have the right to file
a motion to consolidate such Impasse Notices with EMC’s Impasse Notice in a single proceeding. The motion to consolidate such Impasse Notices shall be served within ten (10)
  

 68 

 Business Days of the date when each entity within the EMC Group has provided notice as to whether or not it will
voluntarily proceed in a consolidated arbitration. Duke’s motion to consolidate shall be decided in the first commenced arbitration by one arbitrator (if the Streamlined Arbitration Process is used) or one (1) arbitration panel (if the
Standard Arbitration Process is used), provided that the arbitrator(s) shall satisfy the qualifications required pursuant to the third sentence of Section 14.6.1(1) or Section 14.6.2(2), as applicable, with respect to all entities in the
arbitration proceedings that are the subject of the motion to consolidate. If Impasse Notices are simultaneously given by EMC and one or more other entities within the EMC Group, then Duke shall have sole discretion to designate which of the Impasse
Notices shall be treated as the first given for purposes of determining which arbitrator(s) shall decide the motion to consolidate, and shall provide written notice of such designation in the motion to consolidate arbitrations. The procedures set
forth in Sections 14.6.1 and 14.6.2 for each arbitration proceeding in which the motion to consolidate was not filed shall be held in abeyance pending the decision on the motion to consolidate by the arbitrator(s) in the arbitration proceeding in
which the motion to consolidate was filed. 
 In determining whether consolidation of one or all is appropriate, the arbitrator(s) shall
consider whether the same or substantially similar issue or issues will be subject to the arbitration(s); EMC’s reasons for opposing consolidation and Duke’s reasons for seeking consolidation; and the fundamental fairness and efficiency in
proceeding individually, jointly or consolidated. The arbitrator(s) decision on the motion to consolidate shall be binding on the Parties and not subject to appeal. 
 In the event the motion to consolidate is denied (unless otherwise agreed by the Parties and the other entities of the EMC Group that have provided or received such Impasse Notices), the arbitrations shall each
proceed, subject to resolution of scheduling issues, with no arbitration being stayed as a result of the denial of the motion. In the event the motion to consolidate is granted, each entity within the EMC Group, other than the entity which is a
party to the proceeding in which the motion to consolidate was filed, shall move for dismissal of the respective arbitration actions in which it is a party. 
 14.3.1 Individual Treatment of EMC in Joint or Consolidated Arbitration. For purposes of joint or combined arbitration, all of the entities within the EMC Group participating in the proceeding shall be treated
as one (1) Party for purposes of Article 14, with the following exceptions. First, EMC shall be treated as a separate Party for purposes of Selection of Arbitration Process set forth in Section 14.4. Second, EMC may reach its own
independent, voluntary resolution with Duke and may pursue its own strategy and prosecute its case with its own legal counsel in the joint or combined arbitration. Third, EMC will be treated as a separate Party for purposes of discovery in
Section 14.6.1(4) or 14.6.2(4). Fourth, EMC will be treated as a separate Party for purposes of a Submission and for the adoption of the resolution and the associated monetary amount with respect to the ultimate decision of the arbitrator(s).
Fifth, EMC will be treated as a separate Party for purposes of the third sentence of Section 14.6.1(1) and Section 14.6.2(2). 
 14.4 Selection
of Arbitration Process. No later than thirty (30) Days following receipt of the Impasse Notice, or any longer time period as agreed to by the Parties, the Parties shall agree on which arbitration process specified herein to use: either the
Standard Arbitration Process or the 
  

 69 

 Streamlined Arbitration Process. Should the Parties fail to agree on the arbitration process within thirty (30) Days

	14.6	Arbitration Processes. 

 14.6.1 Standard
Arbitration Process. The following shall be the process that is used, in accordance with this Article 14, as the Standard Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the
purposes of that arbitration alone modify or forego any procedural requirement or rule specified hereunder as part of the Standard Arbitration Process: 
 (1) Selection of Arbitrators. The Party initiating arbitration shall nominate one (1) arbitrator no later than fifteen (15) Days following the Selection Date. The other Party shall nominate one
(1) arbitrator no later than thirty (30) Days after the Selection Date. Each of the two Party-nominated arbitrators shall be unaffiliated with any of the Parties or their predecessors or Affiliates; shall not be current or former employees
of the nominating Party or its predecessors or Affiliates and shall be without material financial alliance with the nominating Party or its predecessors or Affiliates such that said arbitrator is able to participate in the arbitration without
evident partiality or actual bias in favor of the nominating Party; unless such pecuniary interest or affiliation is expressly acknowledged and waived by all Parties. The two (2) arbitrators shall jointly appoint a third (3rd), neutral arbitrator within thirty (30) Days after the nomination of the second (2nd) arbitrator. The neutral arbitrator shall be the chairperson of the tribunal. This thirty (30) Day period may be extended to sixty
(60) Days by agreement of both Parties. If the two (2) arbitrators are unable to agree on a third (3rd) arbitrator within the specified time period, then a third (3rd) arbitrator shall be selected by the CPR with due regard given
to the selection criteria herein and in the subsequent subsections of Article 14 and input from the Parties and other arbitrators. The Parties shall request CPR to complete selection of the third (3rd) arbitrator no later than thirty (30) Days following their request for selection of the arbitrator. Costs charged by CPR for this service shall be
borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by CPR shall be 
  

 70 

 borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that
participate in such consolidated arbitration. In the event CPR should fail to select the third (3rd) arbitrator
within thirty (30) Days following the Parties’ request for selection of the arbitrator, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the third (3rd) arbitrator. Due regard shall be given to the selection criteria and input from the Parties and other arbitrators. Each of the arbitrators shall
take an oath of neutrality. 
 (2) Additional Qualifications of Arbitrators. Unless otherwise agreed to by the Parties,
each of the arbitrators shall be competent and experienced in matters involving the electricity business in the United States. Such experience shall be conclusively demonstrated by ten (10) years or more of electric industry experience as a
practicing attorney or other experience or expertise as agreed to by the Parties. 
 (3) Replacement of Arbitrators. If
prior to the conclusion of the arbitration any arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein shall be appointed in the manner and timeframe (such timeframe
starting anew following the unavailability of the arbitrator to be replaced) described in Section 14.6.1(1) above. 
 (4)
Discovery. Discovery and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, as determined by a majority of the arbitrators. Each Party shall have the right to
propound up to ten (10) interrogatories, the right to request relevant documents and records, conduct depositions (including depositions of experts), designate experts, and obtain the opinion of opposing experts. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit by overnight
delivery and electronic mail to the arbitrators a precise statement of the dispute, a proposed resolution of the dispute, including a monetary amount and the supporting calculations if applicable, and the factual and/or legal support therefor (the
“Submission”). The next Business Day the Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by
overnight delivery and electronic mail to the other Party and the arbitrators a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) sixty
(60) Days following selection of the third (3rd) arbitrator, (ii) forty-five (45) Days after all
pre hearing discovery has been completed, or (iii) forty-five (45) Days after the issuance of the arbitrators’ decision denying a motion to consolidate pursuant to Section 14.3, at which the Parties shall present such evidence,
argument, and witnesses as they may choose. Prior to the beginning of the hearing, the Parties may submit a joint statement of undisputed facts and/or issues to be resolved, if the Parties so agree to submit such statement or if the arbitrators
order submission of the statement. If the Parties agree, or if allowed by a majority of the arbitrators, the Parties each may submit a post-hearing brief to the arbitrators within ten (10) Business Days of completion of the hearing. No reply
briefs shall be allowed unless otherwise permitted by a majority of the arbitrators.

 14.6.2 Streamlined Arbitration Process. The following shall be the process that is used, in
accordance with this Article, as the Streamlined Arbitration Process under this Agreement. By mutual agreement, the Parties may in any given arbitration and for the purposes of that arbitration alone modify or forego any procedural requirement or
rule specified hereunder as part of the Streamlined Arbitration Process: 
 (1) Selection of Arbitrator. No later than
thirty (30) Days following the Selection Date, the Parties shall agree upon a single arbitrator to conduct the arbitration. If the Parties are unable to agree on an arbitrator, then the arbitrator shall be selected by the CPR with due regard
given to input from the Parties and in conformity with the qualifications specified herein. The Parties shall request CPR to complete selection of the arbitrator no later than thirty (30) Days following their request for selection of an
arbitrator. Costs charged by CPR for this service shall be borne one-half (1/2) by Duke and one-half (1/2) by EMC; provided that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by
CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by the entities within the EMC Group that participate in such consolidated arbitration. In the event CPR should fail to select the arbitrator within seventy-five (75) Days
after the Selection Date, then any Party may petition a court of competent jurisdiction in the State of North Carolina to select the arbitrator. Due regard shall be given to the selection criteria and input from the Parties. The arbitrator shall
take an oath of neutrality. 
 (2) Qualification of the Arbitrator. The arbitrator shall be unaffiliated with any of
the Parties or their predecessors or Affiliates, such that the arbitrator: 
 (a) Shall not be a current or former employee,

 (c) Shall be competent in matters involving the electricity business in the United States and shall have ten (10) years or more of
electric industry experience as a practicing attorney or such other experience or expertise as agreed by the Parties; and

 (3) Replacement of Arbitrator. If prior to the conclusion of the
arbitration the arbitrator becomes incapacitated or otherwise unable to serve, then a replacement arbitrator with the qualifications specified herein, shall be appointed in the manner and timeframe (such timeframe starting anew following the
unavailability of the arbitrator to be replaced) described in Section 14.6.2(1) above. 
 (4) Discovery. Discovery
and other pre-hearing procedures shall be conducted as set forth herein, as otherwise agreed by the Parties, or if they cannot agree, 
  

 72 

 as determined by the arbitrator. Each Party shall have the right to propound up to ten
(10) interrogatories, the right to request relevant documents and records, conduct at least three (3) depositions, in addition to obtaining discovery of the opinions of any experts and the right to depose any experts (which are not
included in the three (3) depositions above). Additional discovery may be conducted only as allowed by the arbitrator or agreed by the Parties. 
 (5) Hearing. Within fifteen (15) Days after completion of discovery, each Party shall contemporaneously submit a Submission by overnight delivery and electronic mail to the arbitrator. The next Business
Day, the Parties shall exchange complete Submissions by overnight delivery and electronic mail. Within fifteen (15) Days after receiving the other Party’s Submission, each Party may submit by overnight delivery and electronic mail to the
other Party and the arbitrator a reply statement to the other Party’s Submission. The Parties shall conduct a hearing in Charlotte, North Carolina no later than the later of (i) forty-five (45) Days following selection of the
arbitrator, (ii) forty-five (45) Days after all pre-hearing discovery has been completed, or (iii) forty-five (45) days after the issuance of the arbitrator(s)’ decision denying a motion to consolidate pursuant to
Section 14.3, at which the Parties shall present such evidence, witnesses, and argument as they may choose. Unless otherwise ordered by the arbitrator, at least two (2) Days prior to the beginning of the hearing, the Parties may submit a
joint statement of undisputed facts and/or issues to be resolved if the Parties so agree to submit such statement or if the arbitrator orders submission of the statement. If the Parties agree, or if allowed by the arbitrator, the Parties may each
submit a post-hearing brief to the arbitrator within ten (10) Business Days of completion of the hearing. No reply briefs shall be allowed unless otherwise permitted by the arbitrator. 
 14.7 Decision. The arbitrator (if the Streamlined Arbitration Process is used) or a majority of the arbitrators (if the Standard Arbitration Process is used)
shall render his or their decision in favor of one Party or the other by adopting the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The arbitrator(s) must determine the prevailing Party by
interpreting the meaning and intent of the language of this Agreement, applying the applicable Law to the relevant facts and selecting the arbitration ruling proposed by the Parties that most closely correlated to their decision based upon this
Agreement, the applicable Law and the relevant facts. In rendering the decision, the arbitrator(s) shall interpret and apply the terms and conditions of this Agreement, and consider any relevant evidence and testimony, but shall not have the power
to add to or modify any provision of this Agreement or to recommend any additions or modifications or to render a decision that does not adopt the resolution and the associated monetary amount requested by the prevailing Party in its Submission. The
arbitrator(s) shall render a decision within thirty (30) Days following the later of the conclusion of the hearing or the submission of post-hearing briefs. The decision shall be rendered in writing and shall be final and binding upon the
Parties. The decision may be filed in a court of competent jurisdiction, confirmed and may be enforced by any Party as a final judgment in such court, but shall have no precedential effect on future arbitrations under or arising out of this
Agreement except for purposes of enforcement in a court of competent jurisdiction or for the assertion of collateral estoppel/issue preclusion or res judicata/claim preclusion in another proceeding. The Parties expressly acknowledge that no
appeal of the arbitrator’s (or arbitrators’) decision shall be allowed. Except as provided in Section 16.6.4 of this Agreement, the arbitrator(s) shall have no authority to award special, exemplary, punitive, or consequential damages.

  

 73 

 14.8 Expenses. The compensation and expenses of the arbitrator(s) shall be chargeable to and borne one-half
(1/2) by Duke and one-half (1/2) by EMC; provided, that if the arbitration proceeds as a consolidated proceeding pursuant to Section 14.3, the costs charged by CPR shall be borne one-half (1/2) by Duke and one-half (1/2) by
the entities within the EMC Group that participate in such consolidated arbitration; provided, however, that each Party shall bear the compensation and expenses of its own counsel and any retained or expert witnesses. Any costs incurred by a Party
in seeking judicial enforcement of any final decision rendered by arbitration conducted under this Article 14 shall be chargeable to and borne exclusively by the Party against whom such court order is obtained. It is expressly acknowledged that the
failure of the entities within the EMC Group that participate in a consolidated arbitration to reach agreement on the allocation of costs among such entities shall not increase Duke’s share of the costs incurred under this Section 14.8 or
Sections 14.6.1(1) or 14.6.2(1) above one-half (1/2) of the total costs at issue. 
 14.9 Effect of Dispute Resolution Procedures. The initiation

 Article 15  
 Credit and Collateral Requirements 
 15.1 Posting
of Collateral. To protect either Party against potential default of payment or performance, any Party that experiences a Material Adverse Change (“MAC”) shall post as collateral an amount equal to the two (2) highest Months of
Duke’s billings to EMC for the previous twelve (12) Months. Such collateral shall be provided by the Party experiencing the MAC in cash, depository agreements, or letters of credit from a financial institution reasonably acceptable to the
Party not experiencing the MAC within three (3) Business Days after the date on which the MAC occurs. Any such depository agreement or letter of credit shall be in a form satisfactory to the Party not experiencing the MAC in its reasonable
discretion. A financing institution participating in a depository agreement or providing a letter of credit entered into for purposes of this Section 15.1 shall be deemed reasonably acceptable by the Party not experiencing the MAC if it has and
maintains a minimum long term credit rating of A- or better from S&P, A3 or better from Moody’s or A- or better from Fitch Ratings, or is with or from CFC and/or CoBank. 
 15.2 Material Adverse Change. Duke shall be deemed to have experienced a MAC if its unsecured, senior long-term debt obligations not supported by third party credit enhancements are rated below BBB- by S &
P and below Baa3 by Moody’s. EMC shall be deemed to have experienced a MAC (a) if it fails to meet the then-current Debt Service Coverage Ratio required 
  

 74 

 of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three
(3) Years, and (b) the then-current Times Interest Earned Ratio required of EMC by RUS, as determined by averaging the two (2) highest annual ratios during the most recent three (3) Years. The failure by either Party to timely
fulfill a payment or reimbursement obligation, including, in the case of Duke a failure to pay Cover Costs, under this Agreement also shall constitute a MAC by that Party. 
 15.3 Continuing Nature of Collateral Requirement. The Party experiencing the MAC must continue to post the collateral until the MAC is cured. The Party not experiencing the MAC shall have the right to draw
upon, use, and dispose of all collateral that is posted under Section 15.1, if the Party experiencing the MAC fails to fulfill any of its payment or reimbursement obligations, including, in the case of Duke a failure to pay Cover Costs, under
this Agreement, and such failure constitutes an Event of Default. In the event any collateral is drawn upon by the Party not experiencing the MAC in accordance with the provisions of Section 15.5, the Party experiencing the MAC shall within
three (3) Business Days fully replenish the collateral to the monetary amount required by Section 15.1. 
 15.4 Interest on Cash Used as
Collateral. Any interest earned on collateral held under a depository agreement with a financial institution shall be paid to the Party posting the collateral in accordance with the terms of the depository agreement. If cash collateral is
posted, the Party holding the cash collateral shall pay interest to the Party posting the cash collateral at the Federal Funds Effective Rate. The Federal Funds Effective Rate is the rate for that Day opposite the caption “Federal Funds
(Effective)” as set forth in the weekly statistical release designated as H.15(519), or any successor publication published by the Board of Governors of the Federal Reserve System. The Party posting the cash collateral shall invoice the Party
holding the cash collateral for interest accrued during the previous Month and the Party holding the cash collateral shall pay such amount within ten (10) Days of receipt of such invoice. 
 15.5 Grant of Security Interest/Remedies. To secure their obligations under this Agreement, any Party posting collateral under Section 15.1 hereby grants to
the Party not experiencing the MAC a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral, cash equivalents collateral and any and all proceeds resulting therefrom or the
liquidation thereof, whether now or hereafter held by, on behalf of, or for the benefit of, that Party, and the posting Party agrees to take such action as the non-posting Party reasonably requires in order to perfect the non-posting Party’s
first-priority security interest in, and lien on (and right of setoff against), such collateral and any and all proceeds resulting therefrom or from the liquidation thereof. Upon or any time after the occurrence or deemed occurrence and during the
continuation of an Event of Default, the Non-Defaulting Party may do any one or more of the following: (i) exercise any of the rights and remedies of a secured party with respect to all collateral, including any such rights and remedies under
Law then in effect; (ii) exercise its rights of setoff against any and all property of the Defaulting Party in the possession of the Non-Defaulting Party or its agent; (iii) draw on any outstanding letter of credit issued for its benefit;
and (iv) liquidate all collateral then held by or for the benefit of the Non-Defaulting Party free from any claim or right of any nature whatsoever of the Defaulting Party, including any equity or right of purchase or redemption by the
Defaulting Party. The Party drawing upon the collateral shall apply the collateral drawn upon or otherwise realized upon the exercise of any rights or remedies granted under this Section 15.5, to reduce the obligations of 
  

 75 

 the Party posting the collateral under this Agreement (the posting Party remaining liable for any amounts owing after
such application), and to return any surplus collateral or proceeds remaining after the posting Party’s obligations are satisfied in full. 
 15.6
Notice, Information. Each Party shall provide the other Party written notice within two (2) Business Days of the occurrence of an MAC affecting the notifying Party or of the occurrence of any event that may reasonably cause a MAC. Duke
shall provide EMC a copy of Duke’s annual report, and any amendments thereto, within thirty (30) Days after the issuance/filing with the Securities and Exchange Commission of such report or amendment. EMC shall provide Duke with (a) a
copy of EMC’s RUS Form 7 each Year, and any amendments to such Form 7, within thirty (30) Days after the filing of such report or amendment with RUS, and (b) the annual Debt Service Coverage Ratio and Times Interest Earned Ratio

RUS, as determined by averaging the two (2) highest annual ratios during the most recent three (3) years, and the then-current Times Interest Earned Ratio required of EMC by RUS, as determined by averaging the two (2) highest annual
ratios during the most recent three (3) years, or 
 (ii) if the transferee or assignee is not an electric membership corporation
organized under Article 2 Chapter 117 of the North Carolina General Statutes, then its unsecured, senior long-term debt obligations not supported by third party credit enhancements are rated BBB- or higher by S&P or Baa3 or higher by
Moody’s (or, in the alternative, whose obligations under this Agreement are guaranteed by a guarantor that meets the foregoing credit standards, provided that the form of the guaranty shall be reasonably satisfactory to Duke). EMC shall be
relieved of all liability under this Agreement arising on and after the effective date of an assignment that satisfies the requirements of this subpart (B)(ii). 
 16.2.1.3 This Agreement shall be binding upon and inure to the benefit of the permitted successors and permitted assigns of the Parties. Any assignment made without a consent required hereunder shall be void and of no
force or effect as against the non-consenting Party. No sale, assignment, transfer, or other disposition permitted by this Agreement shall affect, release, or discharge any Party from its rights or obligations under this Agreement, except as may be
expressly provided by this Agreement or by written agreement of the Parties. 
  

 81 

 16.2.2 Assignment For Security. Notwithstanding any other provision of this Agreement, a Party,
without the other Party’s consent but, if such assigning Party is then a borrower of the RUS, only with the consent of the Administrator, may assign, transfer, mortgage or pledge its interest in this Agreement as security (an “Assignment
for Security”) for any obligation secured by any indenture, mortgage, or similar lien on its system assets without limitation on the right of the secured party to further assign this Agreement, including the assignment to create a security
interest for the benefit of the Government, acting through the Administrator, or for the benefit of any third party. 
 16.2.3 Assignment
By Administrator. After any Assignment for Security to the Administrator or other secured party (including any indenture trustee under any indenture securing the obligations of the Party), the Administrator or other secured party, without the
approval of the other Party, may (i) cause the interest in this Agreement of the Party who made the Assignment for Security to be sold, assigned, transferred or otherwise disposed of to a third party pursuant to the terms governing such
Assignment for Security, or (ii) if the Administrator or other secured party first acquires this Agreement, sell, assign, transfer or otherwise dispose of this Agreement to a third party; provided, however, that in either case the Party who
made the Assignment for Security is in default of its obligations to the Administrator or other secured party that are secured by such security interest. 
 16.3 Liability and Indemnification. 
 16.3.1 Indemnity. Each Party shall indemnify, defend, and hold harmless the
other Party from and against: 
 (1) Any Claims arising from or out of any event, circumstance, act, or incident first
occurring or existing during the period when control and title to any electric energy is vested in such Party as provided in Section 4.5, and 
 (2) Any Governmental Charges for which such Party is responsible under Section 16.7.2. 
 Notwithstanding the foregoing, no Party will be required to indemnify, defend, or hold harmless any other Party from any losses or Claims under this Section 16.3.1 to the extent that such loss or Claim was caused by the other
Party’s gross negligence or willful misconduct. 
 16.3.2 Liability Limitations. 
 16.3.2.1 Limitation of Remedies. THE PARTIES CONFIRM THAT THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT SATISFY THE
ESSENTIAL PURPOSES HEREOF. FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE
LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR 
  

 82 

 DAMAGES AT LAW OR IN EQUITY ARE WAIVED REGARDLESS OF THE FAULT, NEGLIGENCE, OR STRICT LIABILITY OF THE PARTY WHOSE
LIABILITY IS RELEASED OR LIMITED THEREBY. 
 IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY HEREIN PROVIDED, AND EXCEPT AS OTHERWISE
EXPLICITLY PROVIDED IN SECTION 16.6.4, THE RESPONSIBLE PARTY’S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES (INCLUDING INTEREST AS PERMITTED BY APPLICABLE LAW) ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY
AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED (EXCEPT AS PROVIDED IN SECTION 16.29). 
 UNLESS EXPRESSLY HEREIN
PROVIDED, (INCLUDING AS PROVIDED IN SECTION 16.6.4) NO PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, MULTIPLE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR IN
CONTRACT UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY
PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT, OR CONCURRENT, OR ACTIVE OR PASSIVE. 
 16.3.2.2 Disclaimer. EXCEPT AS EXPRESSLY SET
FORTH IN THIS AGREEMENT, EACH PARTY, WITH RESPECT TO THE SUPPLY OF ELECTRIC ENERGY AND CAPACITY TO THE OTHER, EXPRESSLY NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN OR ORAL, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY
REPRESENTATION OR WARRANTY WITH RESPECT TO CONFORMITY TO MODELS OR SAMPLES, MERCHANTABILITY, OR FITNESS FOR ANY PARTICULAR PURPOSE. 
 16.3.2.3 Duty to Mitigate. Each Party agrees that is has a duty to mitigate damages, and each covenants that it shall use commercially reasonable efforts to minimize any damages it may incur as a result of the other Party’s
performance or nonperformance of this Agreement. 
 16.4 Force Majeure. Unless otherwise provided by this Agreement, the term “Force
Majeure” means an event or circumstance that: (i) prevents the Party claiming to be affected by it (the “Claiming Party”) from performing its obligations in whole or in part under this Agreement; (ii) is not within the
reasonable control of the Claiming Party, or the result of the negligence of the Claiming Party, and (iii) by the exercise of due diligence, the Claiming Party is unable to overcome in a commercially reasonable manner, and, without limiting the
scope of the definition, includes acts of God, or the public enemy, or insurrection, riot, acts of terrorism, civil disturbance or disorder, strikes, fire, earthquakes, floods, storms or other natural disasters, or actions or restraints by court
order or Governmental Authority or arbitration award (so long as the Claiming Party has not sought or has opposed, to the extent reasonable, such actions or restraints). To the extent that the Claiming Party is prevented by Force Majeure from
carrying 
  

 83 

 out, in whole or part, its obligations hereunder and such Party gives notice and details of the Force Majeure to the
other Party (the “Non-Claiming Party”) as soon as practicable, then the Claiming Party shall be excused from the performance of its obligations other than the obligation to make payments then due or becoming due in respect to performance
prior to the Force Majeure, except as otherwise explicitly provided in this Agreement. The Claiming Party shall remedy the Force Majeure event with all reasonable dispatch. The Non-Claiming Party shall not be required to perform or resume
performance of its obligations to the Claiming Party corresponding to the obligations of the Claiming Party excused by Force Majeure during the period that such Force Majeure remains in effect. Duke shall not adversely distinguish between EMC’s
Native Load and Duke’s Native Load in claiming an event of Force Majeure. 
 16.5 Events of Default and Remedies. 
 16.5.1 Events of Default. For the purposes of this Agreement, an “Event of Default” means, with respect to a Party (a “Defaulting
Party”), the occurrence of any of the following: 
 (1) The failure to make, when due, any payment or reimbursement
required by this Agreement (including any amounts to be credited by one Party to the other Party) or to post or maintain collateral required by this Agreement, if such failure is not remedied within three (3) Business Days after receipt of
written notice of such failure is given to the Defaulting Party by the other Party (“Non-Defaulting Party”). For the purposes of this Section 16.5.1(1), withholding one half (1/2) of a Disputed Amount in accordance with
Section 13.5 shall not constitute failure to make, when due, a payment; 
 (2) Any representation or warranty made by
such Party herein is false or misleading in any material respect when made or when deemed made or repeated; 
 (3) The failure
to perform any material covenant or material obligation set forth in this Agreement (except to the extent constituting a separate Event of Default under this Section 16.5), if such failure is not remedied within three (3) Business Days
after receipt of written notice thereof to the Defaulting Party, provided, that a Party’s failure to perform its obligations under Section 16.1.2.1(iii) or Section 16.1.2.2(iv) shall not in and of itself constitute a material failure
to perform a material covenant or material obligation unless such failure, in the case of Duke, results in a substantial and continuing degradation in reliability of service hereunder or, in the case of EMC, results in a substantial and continuing
degradation in performance hereunder; 
 (4) Such Party becomes Bankrupt; 
 (5) The loss of any authorization from Governmental Authorities necessary to perform its obligations hereunder in accordance with the
terms of this Agreement; 
 (6) Such Party consolidates or amalgamates with, or merges with or into, or transfers all or
substantially all of its assets to, another entity and, at the 
  

 84 

 time of such consolidation, amalgamation, merger, or transfer, the resulting, surviving, or transferee
entity fails to assume all of the obligations of such Party under this Agreement to which it or its predecessor was a party by operation of law or pursuant to an agreement reasonably satisfactory to the other Party; 
 (7) The occurrence and continuation of a default, event of default, or other similar condition or event that under one or more agreements
or instruments, individually or collectively, relating to indebtedness for borrowed money in an aggregate amount of not less than twelve million dollars ($12,000,000) in the case of EMC or one hundred fifty million dollars ($150,000,000) in the case
of Duke, that results in the Party’s indebtedness under such agreements or instruments to become immediately due and payable; and 
 (8) With respect to such Party’s guarantor, if any: 
  

	 	(a)	if any representation or warranty made by a guarantor in connection with this Agreement is false or misleading in any material respect when made or when deemed made or repeated;

  

	 	(b)	the failure of a guarantor to make any payment required or to perform any other material covenant or obligation in any guaranty made in connection with this Agreement and such
failure shall not be remedied within three (3) Business Days after written notice; 

  

	 	(c)	a guarantor becomes Bankrupt; 

  

	 	(d)	the failure of a guarantor’s guaranty to be in full force and effect for purposes of this Agreement (other than in accordance with its terms); or 

  

	 	(e)	a guarantor shall repudiate, disaffirm, disclaim, or reject, in whole or in part, or challenge the validity of any guaranty. 

 16.5.2 Notice of Event of Default. In the event a Party becomes aware of any event or circumstance that constitutes an Event of Default, such
Party shall promptly notify the other Party in writing and by telephone. 
 16.5.3 Effect of Event of Default. If at any time an Event
of Default with respect to a Defaulting Party has occurred and is continuing, the other Party (the “Non-Defaulting Party”) may do one or more of the following: 
 (1) If an Event of Default under Section 16.5.1(1) persists for ten (10) Days or longer, terminate this Agreement in accordance
with the notification required pursuant to Sections 2.3.2.1 and 2.3.3 of this Agreement; or 
  

 85 

 (2) If an Event of Default (other than an Event of Default under Section 16.5.1(1))
persists for sixty (60) Days or longer, terminate this Agreement in accordance with Sections 2.3.2.1 and 2.3.3 of this Agreement, provided, however, that if the Defaulting Party is diligently pursuing cure, but such Event of Default is not
capable of being cured within sixty (60) Days, then the period for the Defaulting Party to cure such Event of Default shall be extended from sixty (60) Days to one hundred eighty (180) Days before the Non-Defaulting Party may exercise
its right to terminate this Agreement pursuant to this Section 16.5.3(2). 
 16.5.4 Enforcement of Remedies. The Non-Defaulting
Party may exercise any rights or remedies available at law or equity, subject to the provisions of Article 14 and Sections 15.5 and 16.3 of this Agreement. No delay or failure on the part of a Non-Defaulting Party to exercise any right or
remedy to which it may become entitled on account of an Event of Default shall constitute an abandonment of any such right, and the Non-Defaulting Party shall be entitled to exercise such right or remedy at any time during the continuance of an
Event of Default notwithstanding any delay in enforcing such right. No waiver of any Event of Default shall constitute a waiver of any later Event of Default; all such waivers shall be in writing and shall in no circumstance be deemed effective
unless such waiver is made in writing. All of the remedies and other provisions of this Section 16.5 shall be without prejudice and in addition to any right of setoff, recoupment, combination of accounts, lien, or other right to which any Party
or any of its Affiliates is at any time otherwise entitled, whether by operation of law or in equity, under contract, or otherwise. 
 16.6 Confidential
Information. 
 16.6.1 Prior Confidentiality Agreements Unaffected. Any preexisting confidentiality agreements entered into by the
Parties pertaining to the negotiation and development of this Agreement shall survive by their terms and shall not be considered modified by this Agreement. 
 16.6.2 Authorized Disclosure. Each Party agrees to preserve, to the maximum extent permitted by Law, the confidentiality of Confidential Information supplied to it by the other Party either during the
negotiations leading to this Agreement or during the course of implementing, performing or winding up this Agreement. A Party may disclose Confidential Information received from the other Party to the receiving Party’s Affiliates, auditors,
attorneys, consultants, advisors, persons providing financing to the receiving Party, other entities in the EMC Group that have entered into substantially similar agreements, and to other third parties as may be necessary for the receiving Party to
perform its obligations under this Agreement, provided that any such persons agree in writing to be bound by the confidentiality provisions of this Agreement. Notwithstanding anything contained in this Section 16.6, Confidential Information may
be disclosed to any Governmental Authority requiring such Confidential Information, provided that: (i) such Confidential Information is submitted under applicable provisions, if any, for confidential treatment by such Governmental Authority;
(ii) prior to such disclosure, the Party who supplied the information is given notice of the disclosure requirement (if time permits and the other Party’s counsel determines that such notice is permitted by Law) so that it may take at its
own risk and expense whatever action it deems appropriate, including intervention in any proceeding and the seeking of an injunction to prohibit such disclosure; and (iii) the Party subject to the Governmental Authority endeavors to protect the
confidentiality of 
  

 86 

 any Confidential Information to the extent reasonable under the circumstances and to use its good faith efforts to
prevent the further disclosure of any Confidential Information provided to any Governmental Authority. The Parties recognize that Duke is required to file periodic reports with FERC that disclose certain price, quantity, and related data, and such
filings shall not be deemed a violation of this section. 
 16.6.3 Survival of Confidentiality Obligations. Confidential Information
received from the other Party shall be kept confidential in accordance with the terms of this Agreement for at least five (5) Years after the termination of this Agreement. 
 16.6.4 Right to Remedies. In the event of an unauthorized disclosure to a third party, the limitations on remedies contained in
Section 16.3.2.1 shall not apply, and, in the event of a breach, Parties shall not have an adequate remedy at law and accordingly shall, in addition to any other available legal or equitable remedies, be entitled to an injunction against such
breach without any requirement to post a bond as a condition of such relief. 
 16.7 Governmental Liabilities. 
 16.7.1 Minimization of Tax Liability. Each Party shall use reasonable efforts to implement the provisions of and to administer this Agreement in
accordance with the intent of the Parties to minimize all taxes, so long as neither Party is materially adversely affected by such efforts. 
 16.7.2 Governmental Charges. 
 16.7.2.1 With respect to sales of electric energy made by Duke to EMC, Duke shall pay or cause
to be paid all Governmental Charges imposed by any Government Authority on or with respect to such sales of electric energy to the extent such Governmental Charges arise prior to the Delivery Point. EMC shall pay or cause to be paid all Governmental
Charges on or with respect to such sale of electric energy to the extent such Governmental Charges arise after the Delivery Point (other than ad valorem, franchise, or income taxes that are related to the sale of such product and are, therefore, the
responsibility of Duke). 
 16.7.2.2 With respect to sales of electric energy by EMC to Duke, EMC shall pay or cause to be paid all
Governmental Charges on or with respect to the sale of the electric energy to Duke. 
 16.7.2.3 In the event a Party is required by Law to
remit or pay Governmental Charges that are the other Party’s responsibility hereunder, the Party ultimately liable for the Governmental Charge shall promptly reimburse the remitting Party for such Governmental Charges; provided further that tax
liabilities may be netted pursuant to Section 13.4 of this Agreement. Nothing will obligate or cause a Party to pay or be liable to pay any Governmental Charges for which it is exempt under the Law. 
 16.7.3 Records. If with respect to either Party, any purchase or sale of electric energy is exempt from Governmental Charges it shall, upon
written request of the other Party, provide a certificate of exemption or other reasonably satisfactory evidence of exemption, and shall use reasonable efforts to obtain and cooperate with obtaining any exemption from or reduction of any
Governmental Charges. 
  

 87 

 16.7.4 Cost of Obtaining FERC Approval. The Parties agree that all fees assessed by FERC, or
expenses incurred in obtaining the approval of FERC for this Agreement, shall be the sole responsibility of Duke. 
 16.7.5 Cost of
Obtaining RUS Approval. The Parties agree that all fees assessed by the RUS, or expenses incurred in obtaining the approval of RUS for this Agreement, shall be the sole responsibility of EMC. 
 16.8 Choice of Law. The validity, interpretation and performance of this Agreement and the rights and duties of the Parties arising out of this Agreement
shall be governed by and construed, enforced, and performed in accordance with the Laws of the State of North Carolina. No principle, doctrine, or rule of conflicts of law shall modify or alter the applicability of the Laws of the State of North
Carolina to this Agreement. 
 16.9 Survival of Obligations. Upon the termination of the Parties’ delivery, sale, purchase, and related service
obligations under this Agreement, any monies, penalties or other charges due and owing under this Agreement shall be paid, any corrections or adjustments to payments previously made shall be determined, and any refunds due shall be made, as soon as
practicable but no later than sixty (60) Days after such termination. All indemnity and confidentiality obligations and audit rights shall survive the termination of this Agreement in accordance with their respective terms. Upon the effective
date of any termination of this Agreement, each Party’s obligations provided for in this Agreement will survive termination and remain in effect solely for the purpose of complying with the provisions of this Section 16.9; OTHERWISE, AS
PROVIDED IN ARTICLE 2, TERMINATION OF THIS AGREEMENT IS ABSOLUTE, AND NO OTHER OBLIGATIONS, DUTIES, OR RIGHTS WHATSOEVER ARISING UNDER THIS AGREEMENT SHALL REMAIN IN EFFECT FOLLOWING THE TERMINATION OF THIS AGREEMENT. 
 16.10 Entire Agreement. This Agreement, and the Schedules and Attachments attached hereto, constitute the entire and integrated agreement between the Parties
relating to the rates, terms, and conditions set out in this Agreement as of the Effective Date. This Agreement supersedes all prior agreements (other than the Confidentiality Agreement which became fully executed on November 22, 2004) whether
oral or written, related to the subject matter of this Agreement. The terms of this Agreement, including any Schedules and Attachments attached hereto, are controlling, and no parol or extrinsic evidence, including but not limited prior drafts or
projections of future costs or rates, shall be used to vary, contradict, or interpret the express rates, terms, and conditions of this Agreement or as a basis for challenging the justness and reasonableness of any rate, term, or condition of this
Agreement. 
  

	16.11	Cost Projections. 

 16.11.1 Duke Cost
Projections. Duke makes no warranties or representations whatsoever concerning any cost or rate projections that it provided in connection with the negotiations leading up to the execution of this Agreement and any such projections provided by

  

 88 

 Duke under Section 16.26 of this Agreement. EMC assumes the risk of reliance on any projected costs or rates
provided by Duke in connection with the negotiations leading up to the execution of this Agreement or any projections provided by Duke under Section 16.26. Any differences between projected costs or rates provided by Duke and actual costs or
rates will not limit or in any way affect the rates, terms, or conditions of this Agreement or any of the Parties’ rights and obligations hereunder. 
 16.11.2 EMC Cost Projections. EMC makes no warranties or representations whatsoever concerning any cost or rate projections that it provided in connection with the negotiations leading up to the execution of
this Agreement and any such projections provided by EMC during the Term. Duke assumes the risk of reliance on any projected costs or rates provided by EMC in connection with the negotiations leading up to the execution of this Agreement or any
projections provided by EMC during the Term. Any differences between projected costs or rates provided by EMC and actual costs or rates will not limit or in any way affect the rates, terms, or conditions of this Agreement or any of the Parties’
rights and obligations hereunder. 
 16.12 Unique Agreement. This Agreement shall not establish any precedent for any other services, or be relied
upon by either Party for any purpose other than for the services and payments provided herein. 
 16.13 No Transfer of Rights. Except as explicitly
provided herein, nothing in this Agreement shall be construed to transfer any rights or obligations that either Party has under any other agreement to the other Party. 
 16.14 No Partnership. The Parties are independent contractors. Nothing in this Agreement shall ever be deemed to create or constitute a partnership, joint venture, or association between the Parties, or to
impose a trust or partnership duty, obligation, or liability on or with regard to either of the Parties. 
 16.15 Third Parties. The provisions of
this Agreement shall not impart rights enforceable by any person or entity not a Party or not a permitted successor or assignee of a Party bound by this Agreement. This Agreement shall not be construed to create any third party beneficiary rights of
any sort. 
 16.16 Waiver. No waiver of all or any part of this Agreement shall be valid unless it (a) is reduced to writing, (b) expressly
states that the Parties agree to such waiver, and (c) is signed by the Parties. Except as specifically set forth herein, neither Duke’s nor EMC’s failure to enforce any provision or provisions of this Agreement shall in any way be
construed as a waiver of any such provision or provisions as to any future violation thereof, nor prevent it from enforcing each and every provision of this Agreement at such time or at any time thereafter. The waiver by either Duke or EMC of any
right or remedy shall not constitute a waiver of its right to assert said right or remedy, at any time thereafter, or any other rights or remedies available to it at the time of or any time after such waiver. 
  

	16.17	Time of Essence. Time is of the essence for, in, and throughout this Agreement. 

  

 89 

 16.18 Headings. The descriptive headings of the various Articles and Sections of this Agreement (or any
Schedules and Attachments attached hereto) have been inserted for convenience of reference only and in no way shall be deemed to modify or restrict any of the terms or provisions hereof. 
 16.19 Severability. Wherever possible, each provision of this Agreement (including any Schedules or Attachments attached hereto) shall be interpreted in a manner as to be effective and valid under applicable
Law, but if any provision contained herein shall be found or ruled to be invalid, illegal, or unenforceable in any respect and for any reason, such provision shall be ineffective to the extent, but only to the extent, of such invalidity, illegality,
or unenforceable without invalidating the remainder of the provision or any provision of this Agreement, and in such event, the Parties shall attempt to negotiate amendments to this Agreement that would permit each Party to realize the equivalent
value of the economic bargain contemplated by this Agreement absent such finding or ruling. 
 16.20 Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall be an original, but all of which together shall constitute one and the same instrument. 
 16.21 No Public
Announcement. The Parties agree that no press release or public announcement concerning the transaction contemplated by this Agreement will be made unless mutually agreed to by the Parties in writing; provided, however, such mutual agreement
will not be required if: 
 (a) The disclosing Party determines that disclosure is reasonably necessary to (i) comply
with applicable Laws of a Governmental Authority having jurisdiction; or (ii) obtain financing for the transaction contemplated by this Agreement; or 
 (b) the disclosure is limited to the following information: (i) the names of the Parties; (ii) the type of service being provided; (iii) the Term; and (iv) the total load being served. 

The disclosing Party shall provide the other Party with written notice of such disclosure at least five (5) Business Days prior to such
disclosure. 
 16.22 Notices. Unless otherwise provided in this Agreement, any notice, consent, or other communication required to be made under this
Agreement shall be in writing and shall be delivered in person, by certified mail (postage prepaid, return receipt requested), or by nationally recognized overnight courier (charges prepaid), in each case properly addressed to such Party as shown
below. Any Party may from time to time change its address, designee or contact information for the purposes of notices, consents, or other communications to that Party by a similar notice specifying a new address, but no such change shall become
effective until it is actually received by the Party to be charged with its contents. All notices, consents, or other communications required or permitted under this Agreement that are addressed as provided in this Section 16.22 shall be deemed
to have been given upon delivery if delivered in person, or upon deposit if delivered by overnight courier or certified mail.

 The Parties may agree on alternative methods of giving operational and scheduling
notices, consistent with the requirements of the applicable Transmission Providers and/or generation scheduling providers. 
 16.23 No Dedication of the
System. No undertaking by either Party to the other Party under any provision of this Agreement shall constitute the dedication of the system, or any portion thereof, of either Party to the public or to the other Party, and it is understood and
agreed that any such undertaking by either of the Parties shall cease after the termination date of this Agreement. The sale by Duke to EMC of electric capacity and energy under this Agreement does not constitute a sale, lease, transfer, or
conveyance of any kind of ownership interest in or to any of Duke’s facilities of any kind. 
 16.24 Stranded Costs. 
 16.24.1 If a Party or any of its Affiliates becomes entitled to receive compensation associated with stranded generation, transmission, distribution or
other assets or costs, the other Party shall have no claim or entitlement to any such compensation. 
 16.24.2 Neither EMC nor Duke shall
have the obligation or liability to the other Party for the payment of any amounts authorized by statute or ordered or approved by a Governmental Authority and that are attributable to or in any way arising from stranded 
  

 91 

 generation, transmission, distribution, or other assets or costs or any liability associated therewith, whether such
amounts are characterized as competitive transition charges, wire charges, or other costs or charges, provided that nothing herein shall limit the damages that may otherwise be recovered for an Event of Default. An order on stranded costs shall not
be deemed a Material Adverse Ruling. 
 16.25 Electric Peak Load and Energy Information to be provided by EMC. Prior to October 1, 2006, and each
October 1 thereafter during the Term, EMC shall provide Duke with forecast projections of (a) EMC’s Monthly electric peak load and electric energy requirements for the following Year and (b) EMC’s annual electric peak load
and electric energy requirements for the following ten (10) years, to the extent EMC has such information available, except that, after a Notice of Termination has been given, EMC shall not be obligated to provide such information for the
period after the termination date. To the extent such information is provided in a report to the RUS that is publicly available, EMC may satisfy this requirement by providing a copy of such report to Duke. 
 16.26 Demand and Energy Charge and Rate Information to be Provided by Duke. Prior to December 1, 2006, and each December 1 thereafter during the Term,
Duke shall provide EMC with forecast projections of (a) the annual electric capacity and energy rates under Sections 7.2 or Section 7.3 (as applicable) for the following year, (b) Monthly demand and electric energy charges under
Section 7.2 or Section 7.3 (as applicable) for the following year, and (c) annual demand and electric energy charges under Sections 7.2 or Section 7.3 (as applicable) for the lesser of the remainder of the Term or the following
ten (10) Years, except that, after a Notice of Termination has been given, Duke shall not be obligated to provide such information for the period after the termination date. 
 16.27 Further Assurances. If either Party determines in its reasonable discretion that any further instruments, assurances, or other things are necessary or desirable to carry out the terms of this Agreement,
the other Party shall execute and deliver all such instruments or assurances, and do all things reasonably necessary or desirable to carry out the terms of this Agreement.

Governmental Authorities having jurisdiction over the matters set forth in this Agreement. 
 16.29 Equitable Relief. Nothing in this Agreement shall
be construed to limit the injunctive or equitable powers of a court of competent jurisdiction. 
 16.30 PURPA Assistance. Duke shall provide
assistance to EMC, as EMC reasonably requests, to support EMC’s compliance with the generation efficiency and fuel diversity standards under PURPA. 
 16.31 SERC and NERC Data Reporting and Compliance Assistance. Duke shall report EMC’s actual load, forecasted load (as provided by EMC to Duke), and resource information to SERC and NERC and their successors, in a manner similar
to the manner in which Duke reports such information for other wholesale full or partial requirements customers with service as firm as Duke’s Native Load. In addition, Duke shall provide assistance and consultation to EMC, to the extent agreed
to by the Parties, to support EMC’s compliance with such organizations’ data reporting requirements.

 Schedule 1 
 Annual Production Capacity and Energy Rates 
 Schedule 1 Methodology: 
 This formula sets forth the method that Duke will use to determine its annual Demand Rates, Fuel Rates, and Variable O&M Rates (collectively, “Rates”). The
Rates will be annual formula rate calculations. The Rates shall initially be estimated for the period January 1, 2007 - December 31, 2007, and shall be estimated continuing thereafter for successive twelve month periods (e.g., January 1,
2008 - December 31, 2008, etc.). Beginning July 1, 2008, and each July 1 thereafter, the Rates will be trued-up based on actual costs and loads for the most recent calendar year, using the formula rates set forth below. The calculations
will be based on Duke’s FERC Form 1 data and Duke’s company records. The true-up will include interest on any refunds or surcharges calculated in accordance with the methodology set forth in 18 C.F.R. § 35.19a or its successor. The
formulas for the Rates were designed to include all costs incurred by Duke to own, operate and maintain Duke’s Generation System. The formulas for the Rates may only be amended by the mutual agreement of the Parties or pursuant to
Section 12.3 of the Agreement. Disallowance or any other treatment of any such costs by the NCUC or any other Governmental Authority other than FERC will not have any effect on the inclusion of such costs in the formulas for the Rates as set
forth below.

 II. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During
Light Load Periods (through December 31, 2008) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour
shall be subject to reduction during the period commencing on the Commencement Date and continuing through December 31, 2008 in accordance with the following: 
 A. NCEMC’s contractual right to SO 1996, SOR A and SOR E (654.3 MW rounded to 655 MW) is subject to reduction based on a comparison between 655 MW and NCEMC’s CP&L Native Load (NCNL). 
 B. In the event that NCEMC’s CP&L Native Load during the Hour is less than 655 MW, EMC’s Base Obligation and EMC Group’s Base
Obligation for the Hour shall be reduced as follows: 
 C. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC’s
Base Obligation shall be equal to the amount set forth in Equation 1 below: 
 Equation 1: ( ( 655 MW - NCNL ) / 225 ) * 11 
 D. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC’s Base Obligation shall be equal to 11 MW plus the amount set forth in Equation
2 below: 
 Equation 2: ( ( 430 MW - NCNL ) / 225 ) * 11 
  

 3 

 E. If 655 MW minus NCNL is equal to or less than 225 MW, the reduction in EMC Group’s Base
Obligation shall be equal to the amount set forth in Equation 3 below: 
 Equation 3: ( ( 655 MW - NCNL ) / 225 ) * 33 
 F. If 655 MW minus NCNL is greater than 225 MW, the reduction in EMC Group’s Base Obligation shall be equal to 33 MW plus the amount set forth in
Equation 4 below: 
 Equation 4: ( ( 430 MW - NCNL ) / 225 ) * 33 
 G. Example: If NCNL is equal to 565 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 655 MW – 565
MW ) / 225 ) * 11 or 4.4 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( (655 MW - 565 MW) / 225 ) * 33, or 13.2 MW. 
 III. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods (January 1, 2009 through December 31, 2010) 
 EMC’s Base Obligation and EMC Group’s Base Obligation during an Hour shall be subject to reduction during the period commencing on
January 1, 2009 and continuing through December 31, 2010 in accordance with the following: 
  

 4 

 A. NCEMC’s contractual right to SO 1996 and SOR A (429.3 MW rounded to 430 MW) is subject to
reduction based on a comparison between 430 MW and NCEMC’s CP&L Native Load (NCNL). 
 B. In the event that NCEMC’s CP&L
Native Load during the Hour is less than 430 MW, EMC’s Base Obligation for the Hour shall be reduced as follows: 
 Equation 5: ( (430 MW
- NCNL ) / 225 ) * 11 
 C. In the event that NCEMC’s CP&L Native Load during the Hour is less than 430 MW, EMC Group’s Base
Obligation for the Hour shall be reduced as follows: 
 Equation 6: ( ( 430 MW - NCNL ) / 225 ) * 33 
 D. Example: If NCNL is equal to 340 MW during an Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340
MW ) / 225 ) * 11 MW, or 4.4 MW, and the reduction in EMC Group’s Base Obligation for the Hour shall be equal to ( ( 430 MW – 340 MW ) / 225 ) * 33, or 13.2 MW. 
 IV. Calculation of Reduction in EMC’s Base Obligation and EMC Group’s Base Obligation During Light Load Periods for the Catawba Resource Entitlement 
 In addition to the reductions to EMC’s Base Obligation and EMC Group’s Base Obligation set forth under Sections II and III above, EMC’s
Base Obligation and EMC Group’s Base Obligation shall be subject to reduction as set forth in this Section IV. 
  

 5 

 A. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a
nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC’s Base Obligation for the Hour shall be reduced as follows: 
 Equation 7: (1 - ( NDNL / 623.5 MW) ) * 32 MW 
 B. In the event that NCEMC’s Duke Native Load during an Hour is less than 623.5 MW and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the Hour, EMC Group’s Base Obligation
for the Hour shall be reduced as follows: 
 Equation 8: (1 - ( NDNL / 623.5 MW ) ) * 95 MW 
 C. Example: If NDNL is equal to 561.15 MW during an Hour, and a nuclear unit at Catawba Nuclear Station or McGuire Nuclear Station is off-line or derated during the
Hour, the reduction in EMC’s Base Obligation for the Hour shall be equal to ( 1 - (561.15 MW / 623.5 MW) ) * 32 MW, which equals ( .1 ) * ( 32 MW ), or 3.2 MW, and the reduction in EMC Group’s Base
Obligation for the Hour shall be equal to ( 1 - (561.15 MW / 623.5 MW ) ) * 95 MW, which equals ( .1 ) * ( 95 MW ), or 9.5 MW.

 Example 1 
 Showing the Calculation of Blue Ridge, Piedmont and 
 Rutherford Allocated Shares of the Duke Total Hourly Energy Charge, 
 EMC Group Total Hourly Energy Credit, Inter-EMC Energy Charge and Inter-EMC Energy Credit 
 The
purpose of this attachment is to provide an example showing the calculation of the charges and credits identified above for one Hour. For purposes of this example, Blue Ridge, Piedmont and Rutherford are referred to individually as BR, P and R,
respectively, and collectively as the EMC Group.

	 Intervals 676-900 - Put Signal during each Interval (kW)
	  	9,000	  	0	  	9,000	  	14,000

	3	Interval numbers refer to the Intervals during the Hour (e.g., Interval 1 is the first four seconds of the Hour, Interval 2 is the next four seconds, etc.). The Call
and Put Signals are shown as the same in each of the first 225 Intervals of the Hour, and then again as the same in the next 225 Intervals and so on. This is a simplifying assumption, to make this example less cumbersome. In actual operation, the
Parties anticipate that these positions would change frequently within the Hour.

	  	2,250	  	0	  	2,250	  	3,500

	4	These numbers sum the four-second Call and Put Signals from Part I.A. For example, 6,000 kW delivered by Duke in each of the 225 four-second Intervals (15 minutes)
equal 1,500 kWh (6,000 KW * 225 Intervals / 900 Intervals / Hour = 1500 kWh).

 ATTACHMENT 7-9 
 Demand Rate Adjustment Percentage and Annual Percentage 
 This attachment provides the formulas to be used for calculating
the Demand Rate Adjustment Percentage and Annual Percentage for each calendar year beginning January 1, 2011. 
 The Demand Rate Adjustment Percentage
shall equal the Production Capacity Revenue Requirement Adjustment divided by the Original Production Capacity Revenue Requirement, but not less than zero. 
 Where 
 Production Capacity Revenue
Requirement Adjustment = (Annual Percentage – 4%) * (Original Production Capacity Revenue Requirement + Original Energy Revenue Requirement) 
 And 
 Annual Percentage shall equal the product of the System Gross Plant Difference and the Fixed Charge Rate,
divided by the sum of Original Production Capacity Revenue Requirement and Original Energy Revenue Requirement. For purposes of calculating the Production Capacity Revenue Requirement Adjustment, the Annual Percentage shall be a maximum of 10%.

 System Gross Plant Difference shall equal EMC Plant in Service less NC Retail Plant in Service. (May be positive or negative.) System Gross Plant
Difference shall be decreased as necessary to eliminate differences between EMC Plant in Service and NC Retail Plant in Service related to timing or method of recovery of plant costs (e.g., plant differences due to recovery of construction period
financing costs through inclusion of construction work in progress in rate base). 
 Fixed Charge Rate shall equal
10%. 
 EMC Plant in Service shall equal the average of the total ending balance of Production Plant, General Plant and Intangible Plant according to
Schedule 1 of this Agreement, for the calendar year for which the Production Capacity Revenue Requirement calculation is prepared and total ending balance of Production Plant, General Plant and Intangible Plant according to Schedule 1 of this
Agreement for the previous calendar year calculation of the Production Capacity Revenue Requirement. 
 NC Retail Plant in Service shall equal the sum
of Duke Power Retail Plant in Service and Nantahala Retail Plant in Service, which shall be determined from Company records supporting the total Electric Plant in Service amount on Schedule 3 of NCUC Form E.S.-1 for the 12 month calendar period
corresponding to the Production Capacity Revenue Requirement calculation used for calculating the EMC Plant in Service. 

 Duke Power Retail Plant in Service shall equal the average of the two December balances for the total of
Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly amounts shown on Schedule 3 of NCUC Form E.S.-1 for Duke Power. 
 Nantahala Retail Plant in Service shall equal the average of the two December balances for the total of Production, General and Intangible plant amounts included in the total Electric Plant in Service monthly
amounts shown on Schedule 3 of NCUC Form E.S.-1 for Nantahala Power & Light. 
 Original Production Capacity Revenue Requirement shall equal
the Production Capacity Revenue Requirement before consideration of any adjustments pursuant to Section 7.3.2.3 of the Agreement. 
 Original Energy
Revenue Requirement shall equal the sum of F for purposes of calculating the Fuel Rate in Schedule 1 and Variable Non-Fuel Production Operation and Maintenance Expense for purposes of calculating the Variable O&M Rate in Schedule 1.

the Buyer are governed by and subject to all of the terms and conditions in this Exhibit, unless a specific Resource Summary Attachment explicitly provides otherwise. Unless defined in this Exhibit, all capitalized terms used herein shall have the
respective meanings set forth as Article One of the Wholesale Power Supply Agreement. 
 General Principles 
  

	1.	Buyer is responsible for planning the way it chooses to use any Capacity or Energy delivered pursuant to one of the Resource Summary Attachments governed by this Exhibit. As a part
of the Wholesale Power Supply Agreement, the Parties have agreed to a set of Resource Summary Attachments that collectively are intended to represent a financial approximation of an allocation of the NCEMC Committed Resources on the Effective Date.

  

	2.	For any hour of delivery, Seller will optimize resources around final dispatch for the combined load of all of Seller’s Participating Members, plus the schedules of the Buyer
and other Independent Members. 

  

	3.	Buyer will pay Seller charges for Energy and the delivery of Energy to the Interface Point under terms specified in Resource Summary Attachments and terms specified elsewhere in
this Agreement including but not limited to Sections 2.4, 2.12 and Article Five. 

 Delivery of Allocated Resources 
  

	4.	Energy Scheduled from Buyer’s Independent Member Allocation is delivered to the Interface Point. The cost and expense of all transmission services, including ancillary services
and losses, from the Interface Point are the sole responsibility of Buyer. 

  

	5.	Seller will be deemed the provider of the resources needed for the purposes of tagging and for the designation of resources under the applicable tariffs of the Transmission
Provider(s) selected by Buyer. 

 Scheduling by Buyer 
  

	6.	All Schedules from Buyer for each Independent Member Allocation will be in whole MWs and may not exceed the IM Allocation MW detailed on the Resource Summary Attachment.

  

	7.	Buyer will submit a separate Schedule in conformance with this Exhibit S by System by resource up to the Maximum Scheduling Limit by System, as further described in Paragraph 23 of
this Exhibit S. 

  

	8.	Buyer will be responsible for scheduling and arranging for the delivery of its SEPA allocation. 

  

 - 2 - 

	9.	For any Independent Member Allocation that is designated as producing Must-Take Energy, Buyer is required to Schedule for every hour of every day of the Delivery Period its full
Must-Take Energy obligation from such a resource, and may not amend or reduce its Schedule for that Energy: provided, however, that to the extent that Seller’s obligation to purchase Must-Take Energy from a resource designated as producing
Must-Take Energy is reduced in any hour, Buyer’s hourly Must-Take Energy obligation shall be adjusted by the ratio of Seller’s hourly Must-Take Energy obligation to the Resource Capacity, rounded to whole MWs. The Buyer shall not be
entitled to Schedule Must-Take Energy in an hour in amounts, which exceed the Buyer’s adjusted Must-Take Energy obligation for that hour. 

  

	10.	Buyer is obligated to Schedule resources in accordance with the terms and conditions provided in the Resource Summary Attachments consistent with the minimum run times in the
contracts pertaining to Seller’s purchased and/or owned resources, and Seller will use its good faith efforts to accommodate Buyer’s Schedules that do not meet the minimum run time requirements, but only so long as meeting such
non-conforming Schedules would not likely result in additional costs to Seller or any of its Participating Members. 

  

	11.	Except with respect to Buyer’s Independent Member Allocations that supply Must-Take Energy, Buyer is not obligated to Schedule its Independent Member Allocations consistent
with the minimum volumes in the power supply contracts of Seller that are in force on the Independent Member Effective Date. 

  

	12.	By 7:00 a.m. EPT each day Buyer must provide Seller with an hourly forecast of its load by System for the following day. 

  

	13.	The Buyer may Schedule its resources consistent with the table below. Day-ahead Schedules are those submitted before 8:00 a.m. EPT the day prior to flow. Intra-day Schedules are
those that are requested after the 8:00 a.m. EPT deadline above. All Schedule changes must occur at the top of the hour. Intra-day Schedule changes require two (2) hours advance notice. 

  

			
	 Scheduling
Changes

	 Day Ahead
	 	 Intra-Day

	Unlimited changes up to the IM Allocation MW identified in the Resource Summary Attachment for each resource in whole MWs.	 	Up to two changes to the hourly Schedule for the remainder of the day. Each change to the hourly Schedule shall be no greater than 5%, for a cumulative maximum of 10% each hour. Additional
changes will be accommodated on a best efforts basis.

 Scheduling by Seller 
  

 - 3 - 

	14.	Seller is not obligated to meet Buyer’s final Schedule using the NCEMC Committed Resources associated with the Independent Member Allocations Scheduled by Buyer.

  

	15.	Seller will accept the risk and/or benefit resulting from differences in the cost of resources used to provide Buyer Energy in accordance with its Schedule(s), and the costs Seller
would have incurred had it used NCEMC Committed Resources to meet Buyer’s Schedule of the Scheduled resource(s). 

  

	16.	Should Seller acquire an alternate resource, rather than use an NCEMC Committed Resource to serve Buyer’s Schedule, and that alternate resource is curtailed, Buyer’s
Schedule will be maintained and any penalty, benefit or curtailment will be borne by Seller. 

  

	17.	Should all or any portion of NCEMC Committed Resources that have been Scheduled by Seller and Buyer to meet Buyer’s Schedule in any given hour be interrupted, then Seller shall
try to identify available alternate resources which Seller, in its sole discretion, determines are reasonably priced and suitable to meet Seller’s needs. If Seller determines that such alternate resources are available, Seller may maintain the
Scheduled deliveries to Buyer but at a price to be determined by Seller and communicated to Buyer. If no alternate resources are available to Seller, Buyer’s Schedule will be curtailed. All damages recovered by Seller from the Person
responsible for the interruption in service will be shared with Buyer and every other Member similarly affected by such interruption in service. 

 Operations and Planning 
  

	18.	Buyer will provide Seller with a real time telemetered signal of Buyer’s load for Seller’s use, for purposes of determining when to start and stop the dynamic schedule,
and to Schedule certain Must-Take Energy requirements of NCEMC Committed Resources. 

  

	19.	Seller shall provide and inform the Buyer on each Thursday by 1:00 p.m. EPT of the projected amount of Energy available hourly by Independent Member Allocation by System for
Scheduling by Buyer for the following Saturday through Friday period, including the amount of Must-Take Energy that will be delivered and must be taken hourly. 

  

	20.	By 8:00 a.m. EPT each day, Buyer shall provide an hourly forecast of its Native Load by System for the next seven (7) days. For purposes of this Exhibit S, “Native
Load” shall mean only the load of Buyer’s members. This load forecast will be used by Seller to calculate the hourly Energy available from the Independent Member Allocations that are available to be Scheduled for a given interval of time.

  

	21.	Buyer shall provide Seller on each Thursday by 4:00 p.m. EPT, a projected hourly Schedule of all the Independent Member Allocations governed by this Agreement for the following
Saturday through Friday period. 

  

 - 4 - 

	22.	Seller and Buyer agree on the following checkout and verification process: 

 As soon as practical after midnight, confirm hourly Schedules, energy flows and energy charges by resource and daily totals; 
 Provide a contact person each Business Day for the following: 
 Resolve issues that remain unresolved;

 Perform month-to-date confirmations of hourly Schedules, energy flows and energy charges by resource and daily totals; 
 Finalize monthly checkouts by the second Business Day of the following month; and 
 Coordinate any true-ups that may be required. 
  

	23.	For Buyers having loads in more than one System, Buyer will provide at the Independent Member Election Date and on July 1of each subsequent year, a forecast of the percentage
of its retail load in each System. (The sum of the percentages must equal 100%). The Maximum Scheduling Limit by System for the following calendar year will be calculated by multiplying the percentage of Buyer’s retail load in each System times
the total of Buyer’s Independent Member Allocations for the following calendar year.

 (Part II of II) 
 TERMS AND CONDITIONS 
 FOR OBTAINING TRANSMISSION 
 SERVICES ADEQUATE TO DELIVER 
 FROM THE INTERFACE POINTS 
 ESTABLISHED UNDER THE 
 WHOLESALE POWER SUPPLY AGREEMENT 
 OF NCEMC FOR SALES TO 
 ITS INDEPENDENT MEMBERS

 General Principles and Responsibilities for Transmission: All Resource Summary Attachments associated with
the Wholesale Power Supply Agreement between Seller and Buyer are governed by and subject to the terms and conditions in this Exhibit unless a specific Resource Summary Attachment explicitly provides otherwise. For purposes of this Exhibit, the
Wholesale Power Supply Agreement and each Resource Summary Attachment governed by this Exhibit, the term “Acceptable Transmission Service” means the level of service available at any point in time that is equal to or better than that level
of service currently defined as “Network Integration Transmission Service” under the Open Access Transmission Tariff of the System to which Buyer’s distribution system is physically interconnected, and if connected to more than one
System, then Buyer must have Acceptable Transmission Service for each Interface Point. 
 The following terms for transmission service apply to each Resource
Summary Attachment included as a part of this Agreement. All of these terms assume that the current Open Access Transmission Tariff environment in force on the Effective Date remains in force, without modification or amendment. The Parties hereto
agree that any amendment, modification or change to that tariff or the regulatory environment for the wholesale electric industry, whether by regulation, regulatory action, statute, judicial action, executive decision or order, or otherwise, may
require modification of this Exhibit to restore to Buyer and Seller the benefits that each intended. Such amendments, modifications or changes would include, without limitation, any changes or modifications of the wholesale electric industry
environment based on the Standard Market Design, or the restructuring of the transmission systems or the regulatory oversight of same. If the Parties fail to reach agreement on modifications of this Exhibit, the dispute shall be subject to
arbitration under the Wholesale Power Supply Agreement. 
 Buyer is responsible for planning for and scheduling the receipt of capacity and energy to be
delivered to Buyer. Buyer will be responsible for negotiating, making and keeping in force one or more transmission agreements with the Transmission Provider(s) necessary to perform its obligations under the Wholesale Power Supply Agreement. At a
minimum, Buyer will negotiate, make and keep in force its own Network Integration Service Agreement (“NITSA”) and its own Network Operating Agreement (“NOA”). 
 Subject to and contingent upon the concurrence and agreement of each affected Transmission Provider, the RUS, and the Federal Energy Regulatory Commission (“FERC”), the Parties further agree: 
  

	1.	Buyer is responsible for serving its own load. It will do so through contracts with Seller, along with other resources Buyer will acquire. 

  

	2.	Buyer will have its own transmission agreement(s) with each and any Transmission Provider(s) whose services are needed to move capacity or energy from any Interface Point of the
System(s) to which Buyer’s distribution system is physically interconnected. 

  

	3.	Buyer will negotiate its own NITSA and NOA. Seller will provide assistance with these negotiations as requested. The cost for this assistance will be charged to Buyer separately
from charges for Capacity and Energy billed under Article 5.1 of this Agreement. 

  

 - 7 - 

	4.	Seller will transfer the direct-assigned facilities used for that Buyer, if any, to Buyer’s NITSA once the same has become effective. 

  

	5.	Seller will provide Buyer with contractual rights that financially approximate the hypothetical assignment of a total amount of Seller’s owned and/or purchased resources,
calculated in accordance with the NCEMC Member Power Supply Resource Policy, for purposes of Buyer’s NITSA and NOA designations for energy delivered to the System served by the Transmission Provider with which Buyer has entered its NITSA and
NOA. 

  

	6.	If any need exists or arises to designate, in addition to the contracts with Seller, any other network resources in order to meet Buyer’s load in accordance with the tariffs or
other requirements of the Transmission Provider(s), Buyer has the responsibility to locate, identify and designate such other network resources. 

  

	7.	Buyer will have the obligation to satisfy the requirements of the applicable OATT, and purchase or self-supply, as applicable, any ancillary or other services needed or required to
serve its load. 

  

	8.	Buyer will coordinate with Seller or its scheduling agent under Exhibit S to this Wholesale Power Supply Agreement to assure that the proper schedule is in place each day for
Buyer’s scheduled amount of Energy related to each of Buyer’s Resource Summary Attachments that are governed by this Exhibit. 

  

	9.	In addition to the other responsibilities arising under this Exhibit, Buyer shall be solely liable for any energy imbalance settlement and any other settlements or liabilities to
which a Transmission Customer is exposed at and from the Interface Point(s). If Buyer causes Seller to incur energy imbalance charges, Buyer will reimburse Seller for any charges that Seller incurs.

pursuant to this subsection from time to time; provided that, immediately after each such loan is made, (i) the aggregate outstanding principal amount of such Bank’s Loans to all Borrowers plus the aggregate amount of such

outstanding principal amount of Loans to any Borrower plus the aggregate amount of Letter of Credit Liabilities for the account of such Borrower shall not exceed the

accordance with Section 3.02(b)) and shall be made from the several Banks ratably in proportion to their respective Commitments in effect on the date of Borrowing; provided that, if the Interest Period selected by the Borrower for a

account of such Borrower shall not exceed such Bank’s Percentage of the Maximum Availability of such Borrower; and provided further that no Bank shall be obligated to make a loan pursuant to this subsection if any Commitment shall have
been extended pursuant to Section 2.01(c) to a date later than the Commitment Termination Date of such Bank. Each Borrowing under this Section 2.01(b) shall be made from the several Banks having the same Commitment Termination Date ratably
in proportion to their respective Commitments. 
 (c) Extension of Commitments. Cinergy may, upon notice to the Administrative
Agent not less than 60 days but no more than 90 days prior to any anniversary of the Effective Date, propose to extend the Commitment Termination Dates for an additional one-year period measured from the Commitment Termination Dates then in effect.
The Administrative Agent shall promptly notify the Banks of receipt of such request. Each Bank shall endeavor to respond to such request, whether affirmatively or negatively (such determination in the sole discretion of such Bank), by notice to
Cinergy and the Administrative Agent within 30 days. Subject to the execution by the Borrowers, the Administrative Agent and such Banks of a duly completed Extension Agreement in substantially the form of Exhibit E, the Commitment Termination Date
applicable to the Commitment of each Bank so affirmatively notifying Cinergy and the Administrative Agent shall be extended for the period specified above; provided that no Commitment Termination Date of any Bank shall be extended unless
Banks having Commitments in an aggregate amount equal to at least 51% in aggregate amount of the Commitments in effect at the time any such extension is requested shall have elected so to extend their Commitments. Any Bank which does not give such
notice to Cinergy and the Administrative Agent shall be deemed to have elected not to extend as requested, and the Commitment of each non-extending Bank shall terminate on its Commitment Termination Date determined without giving effect to such
requested extension. Cinergy may, in accordance with Section 8.06, designate another bank or other financial institution (which may be, but need not be, an extending Bank) to replace a non-extending Bank.

the Administrative Agent shall promptly notify each Bank of the contents thereof and of such Bank’s share (if any) of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Borrower. 
 (b) Not later than 1:00 P.M. (New York City time) on the date of each Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address specified in or pursuant to Section 9.01. Unless the
Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Banks available to the Borrower at the Administrative Agent’s
aforesaid address. 
 (c) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Borrowing that
such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in
accordance with subsection (b) of

repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.06 and (ii) in the case of such Bank, the Federal Funds Rate. If
such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Loan included in such Borrowing for purposes of this Agreement. 
 (d) The failure of any Bank to make the Loan to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any,
hereunder to make a Loan on the date of such Borrowing, but no Bank shall be responsible for the failure of any other Bank to make a Loan to be made by such other Bank. 
 Section 2.04. Registry; Notes. (a) The Administrative Agent shall maintain a register (the “Register”) on which it will record the Commitment of each Bank, each Loan made by such Bank
and each repayment of any Loan made by such Bank. Any such recordation by the Administrative Agent on the Register shall be conclusive, absent manifest error. Failure to make any such recordation, or any error in such recordation, shall not affect
the Borrowers’ obligations hereunder. 
 (b) Each Borrower hereby agrees that, promptly upon the request of any Bank at any time,
such Borrower shall deliver to such Bank a duly executed Note, in substantially the form of Exhibit A hereto, payable to the order of such Bank and representing the obligation of such Borrower to pay the unpaid principal amount of the Loans made to
such Borrower by such Bank, with interest as provided herein on the unpaid principal amount from time to time outstanding. 
 (c) Each
Bank shall record the date, amount and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and each Bank receiving a Note pursuant to this Section, if such Bank so elects
in connection with any transfer or enforcement of its Note, may endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the
failure of such Bank to make any such recordation or endorsement shall not affect the obligations of any Borrower hereunder or under the Notes. Such Bank is hereby irrevocably authorized by each Borrower so to endorse its Note and to attach to and
make a part of its Note a continuation of any such schedule as and when required. 
 Section 2.05. Maturity of Loans; Effect of Cash
Collateralization of Letters of Credit. (a) Each Revolving Credit Loan made by any Bank shall mature, and the principal amount thereof shall be due and payable together with accrued interest thereon, on the Commitment Termination
Date of such Bank. 
 (b) The Term Loan of each Bank shall mature, and the principal amount thereof shall be due and payable, together
with accrued interest thereon, on the Final Maturity Date. 
 (c) If any provision of any debt instrument or other agreement or
instrument binding upon any Borrower, including without limitation this Agreement, would be contravened by any deposit required hereunder to cash collateralize any Letter of Credit Liabilities of such Borrower, such Borrower shall either
(x) obtain a waiver of such provision, (y) prepay the debt incurred under such debt instrument and terminate such debt instrument or (z) make other arrangements satisfactory to the Required Banks; it being understood and agreed that
the risk of any such contravention shall be borne solely by the Borrowers and not by the Banks and shall in no event constitute a defense available to any Borrower for nonperformance of its obligations hereunder. 
 Section 2.06. Interest Rates. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the
date such Loan is made until it becomes due, at a rate per annum equal to the Base Rate for such day. Such interest shall be payable quarterly in arrears on each Quarterly Payment Date, at maturity and on the date of termination of the Commitments
in their entirety. Any overdue principal of or overdue interest on any Base Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 1% plus the Base Rate for such day. 
 (b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such day plus the London Interbank Offered Rate applicable to such Interest Period. Such interest shall be payable for each Interest Period on the last day thereof and, if
such Interest Period is longer than three months, at intervals of three months after the first day thereof. 
 The “London
Interbank Offered Rate” applicable to any Interest Period means the rate appearing on Page 3750 of the Telerate Service Company (or on any successor or substitute page of such service, or any successor to or substitute for such service,
providing rate quotations comparable to those currently provided on such page of the Telerate Service, as may be nominated by the British Bankers’ Association for purposes of providing quotations of interest rates applicable to dollar deposits
in the London interbank market) as of 11:00 A.M. (London time) two Euro-Dollar Business Days prior to the commencement of such 

  

 8 

 
Interest Period, as the rate for dollar deposits with a maturity comparable to such Interest Period. In the event that such rate is not so available at such time for
any reason, then the “London Interbank Offered Rate” for such Interest Period shall be the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which deposits in dollars are
offered to each of the Euro-Dollar Reference Banks in the London interbank market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal
amount of the Loan of such Euro-Dollar Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. If any Euro-Dollar Reference Bank does not furnish a timely quotation, the Administrative
Agent shall determine the relevant interest rate on the basis of the quotation furnished by the remaining Euro-Dollar Reference Bank or, if none of such quotations is available on a timely basis, the provisions of Section 8.01 shall apply.

 (c) Any overdue principal of or overdue interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from
and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 1% plus the higher of (i) the sum of the Euro-Dollar Margin for such day plus the London Interbank Offered Rate
applicable to such Loan at the date such payment was due and (ii) the Base Rate for such day. 
 (d) The Administrative Agent shall
determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice to the Borrower and the participating Banks by telecopy, telex or cable of each rate of interest so determined, and its determination
thereof shall be conclusive in the absence of manifest error unless the Borrower raises an objection thereto within five Domestic Business Days after receipt of such notice. 
 Section 2.07. Fees. (a) Facility Fees. Cinergy shall pay to the Administrative Agent, for the account of the Banks ratably in proportion to
their Credit Exposures, a facility fee calculated for each day at the Facility Fee Rate for such day (determined in accordance with the Pricing Schedule) on the aggregate amount of the Credit Exposures on such day; provided that if at any
time Cinergy shall fail to pay such facility fee within five days of the date when such facility fee is due, each of CG&E, PSI Energy and ULH&P severally, but not jointly, agrees to pay upon demand to the Administrative Agent for the account
of each Bank the amount of such unpaid facility fee multiplied by the percentage which the Maximum Availability applicable to such Borrower represents of the aggregate Commitments (it being understood that Cinergy shall remain liable for any unpaid
amounts). Such facility fee shall accrue for each day from and including the Effective Date but excluding the day on which the Credit Exposures are reduced to zero. 
 (b) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent (i) for the account of the Banks ratably a letter of
credit fee accruing daily on the aggregate amount then available for drawing under all outstanding Letters of Credit at a rate per annum equal to the then applicable Euro-Dollar Margin and (ii) for the account of each Issuing Bank a letter of
credit fronting fee accruing daily on the aggregate amount then available for drawing under all Letters of Credit issued by such Issuing Bank at a rate per annum of 0.125% (or such other rate as may be mutually agreed from time to time by the
Borrower and such Issuing Bank). 
 (c) Payments. Accrued fees under this Section for the account of any Bank shall be payable
quarterly in arrears on each Quarterly Payment Date and upon such Bank’s Commitment Termination Date and Final Maturity Date (and, if later, the date the Credit Exposure of such Bank is reduced to zero). 
 Section 2.08. Optional Termination or Reduction of Commitments and Maximum Availabilities. (a) Cinergy may, upon at least three Domestic Business
Days’ notice to the Administrative Agent, (i) terminate the Commitments at any time, if no Loans or Letter of Credit Liabilities are outstanding at such time, or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple of $1,000,000 the aggregate amount of the Commitments in excess of the aggregate Utilization. 
 (b)
Each Borrower, other than Cinergy, may, upon at least three Domestic Business Days’ notice to the Administrative Agent, reduce its Maximum Availability (i) to zero, if no Loans to it or Letter of Credit Liabilities for its account are
outstanding or (ii) by an amount of $10,000,000 or any larger multiple of $1,000,000 so long as, after giving effect to such reduction, its Maximum Availability is not less than the sum of the aggregate principal amount of Loans outstanding to
it and the aggregate Letter of Credit Liabilities outstanding for its account. Upon any reduction in the Maximum Availability of a Borrower to zero pursuant to this Section 2.08(b), such Borrower shall cease to be a Borrower hereunder.

 Section 2.09. Method of Electing Interest Rates. (a) The Loans included in each Borrowing shall bear interest initially at
the type of rate specified by the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the
provisions of Article 8 and the last sentence of this subsection (a)), as follows: 
 (i) if such Loans are Base Rate Loans, the
Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and 
 (ii) if such Loans are
Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate Loans or elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period, subject to Section 2.13 in the case of any such conversion or
continuation effective on any day other than the last day of the then current Interest Period applicable to such Loans. 
  

 9 

 Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the
Administrative Agent not later than 11:00 A.M. (New York City time) on the third Euro-Dollar Business Day before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such notice applies,
and the remaining portion to which it does not apply, are each $10,000,000 or any larger multiple of $1,000,000. 
 (b) Each Notice of
Interest Rate Election shall specify: 
 (i) the Group of Loans (or portion thereof) to which such notice applies; 
 (ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of
subsection 2.09(a) above; 
 (iii) if the Loans comprising such Group are to be converted, the new type of Loans and, if the Loans being
converted are to be Euro-Dollar Loans, the duration of the next succeeding Interest Period applicable thereto; and 
 (iv) if such Loans
are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period. 
 Each Interest Period specified in a
Notice of Interest Rate Election shall comply with the provisions of the definition of the term “Interest Period”. 
 (c) Promptly after receiving a Notice of Interest Rate Election from the Borrower pursuant to subsection 2.09(a) above, the Administrative Agent shall notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower. If no Notice of Interest Rate Election is timely received prior to the end of an Interest Period for any Group of Loans, the Borrower shall be deemed to have elected that such Group of Loans be converted to Base Rate Loans
as of the last day of such Interest Period. 
 (d) An election by the Borrower to change or continue the rate of interest applicable to
any Group of Loans pursuant to this Section shall not constitute a “Borrowing” subject to the provisions of Section 3.02. 
 Section 2.10. Mandatory Termination of Commitments. The Commitment of each Bank shall terminate on such Bank’s Commitment Termination Date. 
 Section 2.11. Optional Prepayments. (a) The Borrower may (i) upon notice to the Administrative Agent not later than 11:00 A.M. (New York City time) on any Domestic Business Day prepay on such
Domestic Business Day any Group of Base Rate Loans and (ii) upon at least three Euro-Dollar Business Days’ notice to the Administrative Agent not later than 11:00 A.M. (New York City time) prepay any Group of Euro-Dollar Loans, in each
case in whole at any time, or from time to time in part in amounts aggregating $5,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment and
together with any additional amounts payable pursuant to Section 2.13. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Group or Borrowing. 
 (b) Upon receipt of a notice of prepayment pursuant to this Section, the Administrative Agent shall promptly notify each Bank of the contents
thereof and of such Bank’s share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower. 
 Section 2.12. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on, the Loans and of fees hereunder, not later than 1:00 P.M. (New York City time) on the date
when due, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address referred to in Section 9.01 and without reduction by reason of any set-off, counterclaim or deduction of any kind. The
Administrative Agent will promptly distribute to each Bank in like funds its ratable share of each such payment received by the Administrative Agent for the account of the Banks. Whenever any payment of principal of, or interest on, the Base Rate
Loans or Letter of Credit Liabilities or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or
interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another
calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such
extended time. 
 (b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any
payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent,
at the Federal Funds Rate. 
  

 10 

 Section 2.13. Funding Losses. If the Borrower makes any payment of principal with respect to any
Euro-Dollar Loan or any Euro-Dollar Loan is converted to a Base Rate Loan or continued as a Euro-Dollar Loan for a new Interest Period (pursuant to Article 2, 6 or 8 or otherwise) on any day other than the last day of an Interest Period applicable
thereto, or if the Borrower fails to borrow, prepay, convert or continue any Euro-Dollar Loans after notice has been given to any Bank in accordance with Section 2.03(a), 2.09(c) or 2.11(b), the Borrower shall reimburse each Bank within 15 days
after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties,
but excluding loss of margin for the period after any such payment or conversion or failure to borrow, prepay, convert or continue; provided that such Bank shall have delivered to the Borrower a certificate setting forth in reasonable detail
the calculation of the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error. 
 Section 2.14.
Computation of Interest and Fees. Interest based on the Base Rate and facility fees hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first
day but excluding the last day). All other interest and Letter of Credit fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). 
  
 Section 2.15. Letters of Credit. 
 (a) Subject to the terms and conditions hereof, each Issuing Bank agrees to issue Letters of Credit hereunder from time to time before its
Commitment Termination Date upon the request and for the account of any Borrower; provided that, immediately after each Letter of Credit is issued, (i) the Utilization shall not exceed the aggregate amount of the Commitments,
(ii) the aggregate outstanding principal amount of Loans to any Borrower plus the aggregate amount of Letter of Credit Liabilities for the account of such Borrower shall not exceed the Maximum Availability of such Borrower and (iii) the
aggregate amount of the Letter of Credit Liabilities shall not exceed $1,000,000,000. Upon the date of issuance by the Issuing Bank of a Letter of Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to
each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation in such Letter of Credit and the related Letter of Credit Liabilities in the proportion its Commitment
bears to the aggregate Commitments; provided that (i) if the scheduled Commitment Termination Date of a Bank falls prior to the expiry date of a Letter of Credit then outstanding and the Commitments of the other Banks are extended on
such date in accordance with Section 2.01(c), such Bank’s participation in such Letter of Credit shall terminate on its Commitment Termination Date, and the participations of the other Banks therein shall be redetermined pro rata in
proportion to their Commitments after giving effect to the termination of the Commitment of such former Bank; and (ii) in the event that the Commitments of the other Banks are not extended in accordance with Section 2.01(c), then such
Bank’s participation in all Letters of Credit shall remain at the level existing prior to the proposed extension, regardless of whether the expiry of any such Letters of Credit extends beyond such Bank’s Commitment Termination Date. If and
to the extent necessary to permit redetermination of the participations in Letters of Credit pursuant to clause (i) of the foregoing proviso within the limits of the Commitments which are not terminated, the Borrowers shall prepay on such date
all or a portion of the outstanding Loans and/or secure cancellation of outstanding Letters of Credit, and such redetermination and termination of participations in outstanding Letters of Credit shall be conditioned upon their having done so.

 (b) The Borrower shall give the Issuing Bank notice at least three Domestic Business Days prior to the requested issuance of a Letter
of Credit, or in the case of a Letter of Credit substantially in the form of Exhibit G, at least one Business Day prior to the requested issuance of such Letter of Credit, specifying the date such Letter of Credit is to be issued and describing the
terms of such Letter of Credit (such notice, including any such notice given in connection with the extension of a Letter of Credit, a “Notice of Issuance”), substantially in the form of Exhibit F, appropriately completed. Upon
receipt of a Notice of Issuance, the Issuing Bank shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Bank of the contents thereof and of the amount of such Bank’s participation in such Letter
of Credit. The issuance by the Issuing Bank of each Letter of Credit shall, in addition to the conditions precedent set forth in Article 3, be subject to the conditions precedent that such Letter of Credit shall be denominated in U.S. dollars and
shall be in such form and contain such terms as shall be reasonably satisfactory to the Issuing Bank. Unless otherwise notified by the Administrative Agent, the Issuing Bank may, but shall not be required to, conclusively presume that all conditions
precedent set forth in Article 3 have been satisfied. The Borrower shall also pay to each Issuing Bank for its own account issuance, drawing, amendment and extension charges in the amounts and at the times as agreed between the Borrower and such
Issuing Bank. Except for non-substantive amendments to any Letter of Credit for the purpose of correcting errors or ambiguities or to allow for administrative convenience (which amendments each Issuing Bank may make in its discretion with the
consent of the Borrower), the amendment, extension or renewal of any Letter of Credit shall be deemed to be an issuance of such Letter of Credit. If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically
renewed unless notice of termination is given by the Issuing Bank of such Letter of Credit, the Issuing Bank shall timely give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which the
Issuing Bank’s notice of termination may be given to the beneficiaries of such Letter of Credit, the Issuing Bank has received a notice of termination from the Borrower or a notice from 

  

 11 

 
the Administrative Agent that the conditions to issuance of such Letter of Credit have not been satisfied or (ii) the renewed Letter of Credit would have a term
not permitted by subsection (c) below. 
 (c) No Letter of Credit shall have a term extending beyond the first anniversary of the
Commitment Termination Date of the applicable Issuing Bank. 
 (d) Upon receipt from the beneficiary of any applicable Letter of Credit
of any notice of a drawing under such Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Bank as to the amount to be paid as a result of such demand
or drawing and the payment date. The Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank upon any drawing under any Letter of Credit without presentment,
demand, protest or other formalities of any kind. All such amounts paid by the Issuing Bank and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate for such day
plus, if such amount remains unpaid for more than two Domestic Business Days, 1%. In addition, each Bank will pay to the Administrative Agent, for the account of the applicable Issuing Bank, immediately upon such Issuing Bank’s demand at any
time during the period commencing after such drawing until reimbursement therefor in full by the Borrower, an amount equal to such Bank’s ratable share of such drawing (in proportion to its participation therein), together with interest on such
amount for each day from the date of the Issuing Bank’s demand for such payment (or, if such demand is made after 12:00 Noon (New York City time) on such date, from the next succeeding Domestic Business Day) to the date of payment by such Bank
of such amount at a rate of interest per annum equal to the Federal Funds Rate and, if such amount remains unpaid for more than five Domestic Business Days after the Issuing Bank’s demand for such payment, at a rate of interest per annum equal
to the Base Rate plus 1%. The Issuing Bank will pay to each Bank ratably all amounts received from the Borrower for application in payment of its reimbursement obligations in respect of any Letter of Credit, but only to the extent such Bank has made
payment to the Issuing Bank in respect of such Letter of Credit pursuant hereto. 
 (e) The obligations of the Borrower and each Bank
under subsection 2.15(d) above shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following
circumstances: 
 (i) the use which may be made of the Letter of Credit by, or any acts or omission of, a beneficiary of a Letter of
Credit (or any Person for whom the beneficiary may be acting); 
 (ii) the existence of any claim, set-off, defense or other rights that
the Borrower may have at any time against a beneficiary of a Letter of Credit (or any Person for whom the beneficiary may be acting), the Banks (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter
of Credit or any document related hereto or thereto or any unrelated transaction; 
 (iii) any statement or any other document presented
under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; 
 (iv) payment under a Letter of Credit to the beneficiary of such Letter of Credit against presentation to the Issuing Bank of a draft or certificate
that does not comply with the terms of the Letter of Credit; provided that the determination by the Issuing Bank to make such payment shall not have been the result of its willful misconduct or gross negligence; or 
 (v) any other act or omission to act or delay of any kind by any Bank (including the Issuing Bank), the Administrative Agent or any other Person or
any other event or circumstance whatsoever that might, but for the provisions of this subsection (v), constitute a legal or equitable discharge of the Borrower’s or the Bank’s obligations hereunder. 
 (f) The Borrower hereby indemnifies and holds harmless each Bank (including the Issuing Bank) and the Administrative Agent from and against any and
all claims, damages, losses, liabilities, costs or expenses which such Bank or the Administrative Agent may incur (including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the Issuing Bank may incur by reason
of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to such Issuing Bank hereunder (but nothing herein contained shall affect any rights the Borrower may have against such defaulting Bank) or
(ii) any litigation arising with respect to this Agreement (whether or not the Issuing Bank shall prevail in such litigation)), and none of the Banks (including the Issuing Bank) nor the Administrative Agent nor any of their officers or
directors or employees or agents shall be liable or responsible, by reason of or in connection with the execution and delivery or transfer of or payment or failure to pay under any Letter of Credit, including without limitation any of the
circumstances enumerated in subsection 2.15(e) above, as well as (i) any error, omission, interruption or delay in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, (ii) any loss or delay in the
transmission of any document required in order to make a drawing under a Letter of Credit and (iii) any consequences arising from causes beyond the control of the Issuing Bank, including, without limitation, any government acts or any other
circumstances whatsoever, in making or failing to make payment under such Letter of Credit; provided that the Borrower shall not be required to indemnify the Issuing Bank for any claims, damages, losses, liabilities, costs or expenses, and
the Borrower shall 

  

 12 

 
have a claim for direct (but not consequential) damage suffered by it, to the extent found by a court of competent jurisdiction to have been caused by (x) the
willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (y) the Issuing Bank’s failure to pay under any Letter of
Credit after the presentation to it of a request strictly complying with the terms and conditions of the Letter of Credit. Nothing in this subsection 2.15(f) is intended to limit the obligations of the Borrower under any other provision of this
Agreement. To the extent the Borrower does not indemnify the Issuing Bank as required by this subsection, the Banks agree to do so ratably in accordance with their Commitments. 
 (g) The Issuing Bank shall act on behalf of the Banks with respect to any Letters of Credit issued by it and the documents associated therewith, and
the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in Article 7 (other than Sections 7.08 and 7.09) with respect to any acts taken or omissions suffered by the Issuing Bank in connection with
Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article 7 included the
Issuing Bank with respect to such acts or omissions and (ii) as additionally provided herein with respect to the Issuing Bank. 
 Section 2.16. Regulation D Compensation. In the event that a Bank is required to maintain reserves of the type contemplated by the definition of “Euro-Dollar Reserve Percentage”, such Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such Bank at a rate per annum determined by such Bank up to but not exceeding the excess of
(i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Bank wishing to require payment of such
additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Bank shall be payable to such Bank at the place indicated in such notice with respect to
each Interest Period commencing at least three Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least three Euro-Dollar Business Days prior to each date on which interest is payable on the
Euro-Dollar Loans of the amount then due it under this Section. Each such notification shall be accompanied by such information as the Borrower may reasonably request. 
 “Euro-Dollar Reserve Percentage” means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the maximum reserve requirement for a member bank of the Federal Reserve System in New York City with deposits exceeding five billion dollars in respect of “Eurocurrency liabilities” (or in respect of any
other category of liabilities which includes deposits by reference to which the interest rate on Euro-Dollar Loans is determined or any category of extensions of credit or other assets which includes loans by a non-United States office of any Bank
to United States residents). 
 Section 2.17. Increase In Commitments; Additional Banks. (a) Subsequent to the Effective Date, Cinergy
may, upon at least 30 days’ notice to the Administrative Agent (which shall promptly provide a copy of such notice to the Banks), propose to increase the aggregate amount of the Commitments, provided that after giving effect to any such
increase, the total Commitments shall not exceed $2,500,000,000 (the amount of any such increase, the “Increased Commitments”). Each Bank party to this Agreement at such time shall have the right (but no obligation), for a period of
15 days following receipt of such notice, to elect by notice to Cinergy and the Administrative Agent to increase its Commitment hereunder. 
 (b) If any Bank party to this Agreement shall not elect to increase its Commitment pursuant to subsection (a) of this Section, Cinergy may designate another bank or other lenders (which may be, but need not be, one or more of the
existing Banks) which at the time agree to (i) in the case of any such lender that is an existing Bank, increase its Commitment and (ii) in the case of any other such lender (an “Additional Bank”), become a party to this
Agreement. The sum of the increases in the Commitments of the existing Banks pursuant to this subsection (b) plus the Commitments of the Additional Banks shall not in the aggregate exceed the unsubscribed amount of the Increased Commitments.

 (c) An increase in the aggregate amount of the Commitments pursuant to this Section 2.17 shall become effective upon the receipt
by the Administrative Agent of an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrowers, by each Additional Bank and by each other Bank whose Commitment is to be increased, setting forth the new Commitments
of such Banks and setting forth the agreement of each Additional Bank to become a party to this Agreement and to be bound by all the terms and provisions hereof, together with such evidence of appropriate corporate authorization on the part of the
Borrower with respect to the Increased Commitments and such opinions of counsel for the Borrower with respect to the Increased Commitments as the Administrative Agent may reasonably request. 
 Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.17, (i) the respective Letter of Credit Liabilities of the Banks shall be
redetermined as of the effective date of such increase and (ii) within five Domestic Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with respect thereto, in the case of any
Euro-Dollar Loans then outstanding, the Borrower shall prepay such Group of Loans in its entirety and, to the extent the Borrower elects 

  

 13 

 
to do so and subject to the conditions specified in Article 3, the Borrower shall reborrow Revolving Credit Loans from the Banks in proportion to their respective
Commitments after giving effect to such increase, until such time as all outstanding Revolving Credit Loans are held by the Banks in such proportion.

 Section 7.03. Action by Administrative Agent. The obligations of the Administrative Agent hereunder are only those expressly
set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default, except as expressly provided in Article 6. 
 Section 7.04. Consultation with Experts. The Administrative Agent may consult with legal counsel (who may be counsel for a Borrower), independent public
accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. 
 Section 7.05. Liability of Administrative Agent. Neither the Administrative Agent nor any of its affiliates nor any of their respective directors,
officers, agents or employees shall be liable to any Bank for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or
willful misconduct. Neither the Administrative Agent nor any of its affiliates nor any of their respective directors, officers, agents or employees shall be responsible for or 

  

 20 

 
have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or agreements of any Borrower; (iii) the satisfaction of any condition specified in Article 3, except receipt of items required to be delivered to the Administrative
Agent; or (iv) the validity, effectiveness or genuineness of this Agreement, the Notes or any other instrument or writing furnished in connection herewith. The Administrative Agent shall not incur any liability by acting in reliance upon any
notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) believed by it in good faith to be genuine or to be signed by the proper party or parties. Without limiting the generality of the
foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties. 
 Section 7.06. Indemnification. Each Bank shall, ratably in accordance with its Commitment, indemnify the Administrative Agent, its affiliates and their
respective directors, officers, agents and employees (to the extent not reimbursed by the Borrowers) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such
indemnitees’ gross negligence or willful misconduct) that such indemnitees may suffer or incur in connection with this Agreement or any action taken or omitted by such indemnitees thereunder. 
 Section 7.07. Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon any Agent or any other Bank, and based on
such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon any Agent or any other Bank, and
based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement. 
 Section 7.08. Successor Administrative Agent. The Administrative Agent may resign at any time by giving notice thereof to the Banks and the Borrowers.
Upon any such resignation, (i) Cinergy, with the consent of the Required Banks (such consent not to be unreasonably withheld or delayed), or (ii) if an Event of Default has occurred and is continuing, then the Required Banks, shall have
the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation,
then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $250,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested
with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder; provided that if such successor Administrative Agent is appointed
without the consent of Cinergy, such successor Administrative Agent may be replaced by Cinergy with the consent of the Required Banks so long as no Event of Default has occurred and is continuing at the time. After any retiring Administrative
Agent’s resignation hereunder as Administrative Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent. 
 Section 7.09. Administrative Agent’s Fee. Cinergy shall pay to the Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon between Cinergy and the Administrative Agent. 
 Section 7.10. Other Agents. None of the Syndication Agent or the
Documentation Agents, in their capacity as such, shall have any duties or obligations of any kind under this Agreement. 
  
 ARTICLE 8 
 CHANGE IN CIRCUMSTANCES 
  
 Section 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing: 
 (a) the Administrative Agent is advised by the Euro-Dollar Reference Banks that deposits in dollars (in the applicable
amounts) are not being offered to the Euro-Dollar Reference Banks in the relevant market for such Interest Period, or 
 (b) Banks
having 66 2/3% or more of the aggregate amount of the affected Loans advise the Administrative Agent that the London
Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Euro-Dollar Loans for such Interest Period, 
 the Administrative Agent shall forthwith give notice thereof to the Borrowers and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, (i) the obligations of the Banks to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each outstanding Euro-Dollar
Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the 

  

 21 

 
Borrower notifies the Administrative Agent at least one Domestic Business Day before the date of any Euro-Dollar Borrowing for which a Notice of Borrowing has
previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing. 
 Section 8.02.
Illegality. If on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund any of its Euro-Dollar Loans and such Bank shall so notify the Administrative
Agent, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrowers, whereupon until such Bank notifies the Borrowers and the Administrative Agent that the circumstances giving rise to such suspension no longer
exist, the obligation of such Bank to make Euro-Dollar Loans, or to continue or convert outstanding Loans as or into Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Bank
shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not be otherwise disadvantageous to such Bank in the good faith exercise of its discretion. If such notice is given, each
Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund
such Loan to such day or (b) immediately if such Bank shall determine that it may not lawfully continue to maintain and fund such Loan to such day. 
 Section 8.03. Increased Cost and Reduced Return. (a) If on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change
in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (the terms “Bank” and “Issuing
Bank” shall include, for purposes of this Section 8.03, the holding company of any Issuing Bank) (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) issued on or after such date of any
such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal
Reserve System, but excluding with respect to any Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its
Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or on the London interbank market any other condition (other than in respect of Taxes or Other Taxes) affecting its Euro-Dollar Loans, its Note or its
obligation to make Euro-Dollar Loans or its obligations hereunder in respect of Letters of Credit and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar
Loan or of issuing or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed
by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), each Borrower shall pay to such Bank its Appropriate Share of such additional amount or amounts as will compensate such Bank for
such increased cost or reduction; provided that no such amount shall be payable with respect to any period commencing more than 90 days prior to the date such Bank first notifies the Borrowers of its intention to demand compensation therefor
under this Section 8.03(a). 
 (b) If any Bank shall have determined that, on or after the date of this Agreement, the adoption of
any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency given or made after the date of this
Agreement, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but
for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy
to the Administrative Agent), each Borrower shall pay to such Bank its Appropriate Share of such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction; provided that no such amount shall be payable with
respect to any period commencing less than 30 days after the date such Bank first notifies the Borrowers of its intention to demand compensation under this Section 8.03(b). 
 (c) Each Bank will promptly notify the Borrowers and the Administrative Agent of any event of which it has knowledge, occurring after the date
hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. 
  

 22 

 (d) The “Appropriate Share” of a Borrower with respect to any amount payable
hereunder is the sum of (i) to the extent such amount is properly allocable to Loans and Letters of Credit outstanding hereunder, the portion of such amount properly allocable to the Loans and Letter of Credit outstanding to or for the account
of such Borrower, and (ii) to the extent such amount is not properly allocable to Loans and Letters of Credit outstanding hereunder, the Appropriate Share shall be the product of the Availability Percentage of such Borrower and such amount.

 Section 8.04. Taxes. (a) For purposes of this Section 8.04, the following terms have the following meanings: 

“Taxes” means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by
the Borrower pursuant to this Agreement or any Note, and all liabilities with respect thereto, excluding (i) in the case of each Bank and the Administrative Agent, taxes imposed on its income, net worth or gross receipts and franchise or
similar taxes imposed on it by a jurisdiction under the laws of which such Bank or the Administrative Agent (as the case may be) is organized or in which its principal executive office is located or, in the case of each Bank, in which its Applicable
Lending Office is located and (ii) in the case of each Bank, any United States withholding tax imposed on such payments except to the extent that such Bank is subject to United States withholding tax by reason of a U.S. Tax Law Change.

 “Other Taxes” means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or
levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note. 
 “U.S. Tax Law Change” means with respect to any Bank or Participant the occurrence (x) in the case of each Bank listed on the signature pages
hereof, after the date of its execution and delivery of this Agreement and (y) in the case of any other Bank, after the date such Bank shall have become a Bank hereunder, and (z) in the case of each Participant, after the date such
Participant became a Participant hereunder, of the adoption of any applicable U.S. federal law, U.S. federal rule or U.S. federal regulation relating to taxation, or any change therein, or the entry into force, modification or revocation of any
income tax convention or treaty to which the United States is a party. 
 (b) Any and all payments by any Borrower to or for the account
of any Bank or the Administrative Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if any Borrower shall be required by law to deduct any Taxes or Other Taxes from any such
payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 8.04) such Bank or the Administrative Agent (as the
case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions, (iii) such Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) such Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.01, the original or a certified copy of a receipt evidencing payment
thereof. 
 (c) Each Borrower agrees to indemnify each Bank and the Administrative Agent for its Appropriate Share of the full amount of
Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 8.04) paid by such Bank or the Administrative Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be paid within 15 days after such Bank or the Administrative Agent (as the case may be) makes demand therefor. 

(d) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on or prior to the date on which it becomes a Bank in the case of each other Bank, and from time to time thereafter as required by law (but only so long as such Bank remains
lawfully able to do so), shall provide the Borrowers two completed and duly executed copies of Internal Revenue Service form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the Internal Revenue Service, or other documentation
reasonably requested by the Borrowers, certifying that such Bank is entitled to benefits under an income tax treaty to which the United States is a party which exempts the Bank from United States withholding tax or reduces the rate of withholding
tax on payments of interest for the account of such Bank or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. 
 (e) For any period with respect to which a Bank has failed to provide the Borrowers with the appropriate form pursuant to Section 8.04(d)
(unless such failure is due to a U.S. Tax Law Change), such Bank shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with respect to any Taxes or Other Taxes which would not have been payable had such form been so
provided; provided that if a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrowers shall take such steps as
such Bank shall reasonably request to assist such Bank to recover such Taxes (it being understood, however, that the Borrowers shall have no liability to such Bank in respect of such Taxes). 
  

 23 

 (f) If any Borrower is required to pay additional amounts to or for the account of any Bank
pursuant to this Section 8.04, then such Bank will take such action (including changing the jurisdiction of its Applicable Lending Office) as in the good faith judgment of such Bank (i) will eliminate or reduce any such additional payment
which may thereafter accrue and (ii) is not otherwise disadvantageous to such Bank. 
 (g) If any Bank or the Administrative Agent
receives a refund (including a refund in the form of a credit against taxes that are otherwise payable by the Bank or the Administrative Agent) of any Taxes or Other Taxes for which any Borrower has made a payment under Section 8.04(b) or
(c) and such refund was received from the taxing authority which originally imposed such Taxes or Other Taxes, such Bank or the Administrative Agent agrees to reimburse such Borrower to the extent of such refund; provided that nothing
contained in this paragraph (g) shall require any Bank or the Administrative Agent to seek any such refund or make available its tax returns (or any other information relating to its taxes which it deems to be confidential). 
 Section 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make or to continue or convert
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) or 8.04 with respect to its Euro-Dollar Loans and the Borrower shall, by at
least five Euro-Dollar Business Days’ prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrowers that the
circumstances giving rise to such suspension or demand for compensation no longer apply: 
 (a) all Loans which would otherwise be made
by such Bank as (or continued as or converted to) Euro-Dollar Loans, as the case may be, shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and

 (b) after each of its Euro-Dollar Loans has been repaid, all payments of principal which would otherwise be applied to repay such
Loans shall be applied to repay its Base Rate Loans instead. 
 If such Bank notifies the Borrowers that the circumstances giving rise to such suspension or demand for
compensation no longer exist, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Banks.

 Section 8.06. Substitution of Bank; Termination Option. If (i) the obligation of any Bank to make or to convert or continue
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Bank has demanded compensation under Section 8.03 or 8.04, (iii) any Bank exercises its right not to extend its Commitment
Termination Date pursuant to Section 2.01(c) or (iv) Investment Grade Status ceases to exist as to any Bank, then: 
 (a)
Cinergy shall have the right, with the assistance of the Administrative Agent, to designate a substitute bank or banks (which may be one or more of the Banks) mutually satisfactory to Cinergy, the Administrative Agent and the Issuing Banks (whose
consent shall not be unreasonably withheld or delayed) to purchase for cash, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto, the outstanding Loans of such Bank and assume the Commitment and Letter of
Credit Liabilities of such Bank, without recourse to or warranty by, or expense to, such Bank, for a purchase price equal to the principal amount of all of such Bank’s outstanding Loans and funded Letter of Credit Liabilities plus any accrued
but unpaid interest thereon and the accrued but unpaid fees in respect of such Bank’s Commitment hereunder and all other amounts payable by the Borrowers to such Bank hereunder plus such amount, if any, as would be payable pursuant to
Section 2.13 if the outstanding Loans of such Bank were prepaid in their entirety on the date of consummation of such assignment; and 
 (b) if at the time Investment Grade Status exists as to the Borrowers, Cinergy may elect to terminate this Agreement as to such Bank; provided that (i) Cinergy notifies such Bank through the Administrative Agent of such election
at least three Euro-Dollar Business Days before the effective date of such termination, (ii) the Borrowers repay or prepay the principal amount of all outstanding Loans made by such Bank plus any accrued but unpaid interest thereon and the
accrued but unpaid fees in respect of such Bank’s Commitment hereunder plus all other amounts payable by the Borrower to such Bank hereunder, not later than the effective date of such termination and (iii) if at the effective date of such
termination, any Letter of Credit Liabilities are outstanding, the conditions specified in Section 3.02 would be satisfied (after giving effect to such termination) were the related Letters of Credit issued on such date. Upon satisfaction of
the foregoing conditions, the Commitment of such Bank shall terminate on the effective date specified in such notice, its participation in any outstanding Letters of Credit shall terminate on such effective date and the participations of the other
Banks therein shall be redetermined as of such date as if such Letters of Credit had been issued on such date.

Bank, at its address or telecopy or telex number set forth in its Administrative Questionnaire or (z) in the case of any party, such other address or telecopy or telex number as such party may hereafter specify for the purpose by notice to the
Administrative Agent and the Borrowers. Each such notice, request or other communication shall be effective (i) if given by telecopy or telex, when such telecopy or telex is transmitted to the telecopy or telex number specified in this Section
and the appropriate answerback or confirmation slip, as the case may be, is received or (ii) if given by any other means, when delivered at the address specified in this Section; provided that notices to the Administrative Agent or any
Issuing Bank under Article 2 or Article 8 shall not be effective until delivered. 
 Section 9.02. No Waivers. No failure or delay by the
Administrative Agent or any Bank in exercising any right, power or privilege hereunder or under any Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. 
 Section 9.03. Expenses; Indemnification. (a) Each Borrower shall pay (i) its Appropriate Share of all reasonable out-of-pocket expenses of the Administrative Agent, including reasonable fees and
disbursements of special counsel for the Agents, in connection with the preparation of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default with respect to such Borrower hereunder and (ii) if
an Event of Default with respect to such Borrower occurs, all reasonable out-of-pocket expenses incurred by the Administrative Agent or any Bank, including reasonable fees and disbursements of counsel, in connection with such Event of Default and
collection and other enforcement proceedings resulting therefrom. 
 (b) Each Borrower agrees to indemnify each Agent and each Bank,
their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such
Indemnitee shall be designated a party thereto) relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans hereunder, in each case to the extent of such Borrower’s Appropriate Share; provided that no
Indemnitee shall have the right to be indemnified hereunder for such Indemnitee’s own gross negligence or willful misconduct as determined by a court of competent jurisdiction. 
 Section 9.04. Sharing of Set-offs. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount then due with respect to the Loans and Letter of Credit Liabilities held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount then due with respect to the
Loans and Letter of Credit Liabilities held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Loans and Letter of Credit Liabilities held by the other Banks, and such other
adjustments shall be made, as may be required so that all such payments with respect to the Loans and Letter of Credit Liabilities held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the
right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of a Borrower other than its indebtedness under this Agreement. 
 Section 9.05. Amendments and Waivers. (a) Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by each Borrower and the Required Banks (and, if the rights or duties of any Agent or any Issuing Bank are affected thereby, by such Person); provided that no such amendment or waiver shall (x) unless
signed by each affected Bank, (i) increase the Commitment of any Bank or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or the amount to be reimbursed in respect of any Letter of
Credit or any interest thereon or any fees hereunder or (iii) postpone the date fixed for any payment of principal of or interest on any Loan or for reimbursement in respect of any Letter of Credit or interest thereon or any fees hereunder or
for termination of any Commitment or (y) unless signed by all Banks, (i) change the definition of Required Banks or the provisions of this Section 9.05 or (ii) change the provisions of Section 9.04. 
 (b) This Agreement may be amended by Cinergy to remove any of CG&E, PSI Energy or ULH&P as a Borrower (a “Removed
Borrower”) hereunder subject to: (i) the receipt by the Administrative Agent of prior written notification from Cinergy of such amendment, (ii) repayment in full of all Loans made to such Borrower, (iii) cash
collateralization of all amounts available for drawing under Letters of Credit issued for the account of such Borrower (or the amendment of such Letter of Credit to provide for Cinergy as the account party) and (iv) repayment in full of all
other amounts owing by such Borrower under this Agreement (it being agreed that any such repayment shall be in accordance with the other terms of this Agreement). Upon the satisfaction of the foregoing 

  

 25 

 
conditions the rights and obligations of such Removed Borrower hereunder shall terminate; provided, however, that the obligations of such Removed Borrower under
Section 9.03 shall survive such amendment. 
 Section 9.06. Successors and Assigns. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns and each Indemnitee, except that no Borrower may assign or otherwise transfer any of its rights under this Agreement without the prior
written consent of all Banks. 
 (b) Any Bank may, with the consent (unless an Event of Default then exists) of Cinergy (such consent
not to be unreasonably withheld or delayed), at any time grant to one or more banks or other institutions (each a “Participant”) participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities;
provided that any Bank may, without the consent of any Borrower, at any time grant participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities to another Bank, an Approved Fund or an Affiliate of such
transferor Bank. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Administrative Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and
the Borrowers, the Issuing Banks and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Any agreement pursuant to which any Bank may
grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrowers hereunder including, without limitation, the right to approve any amendment, modification or
waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (x) (i), (ii) or
(iii) of Section 9.05(a) without the consent of the Participant. Each Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article 8 with respect to its
participating interest, subject to the performance by such Participant of the obligations of a Bank thereunder. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of
this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). 
 (c) Any Bank may at any
time assign to one or more banks or other financial institutions (each an “Assignee”) all, or a proportionate part (equivalent to an initial Commitment of not less than $10,000,000 (unless Cinergy and the Administrative Agent shall
otherwise agree)) of all, of its rights and obligations under this Agreement and its Note (if any), and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D
hereto executed by such Assignee and such transferor Bank, with (and only with and subject to) the prior written consent of the Issuing Banks, the Administrative Agent (which shall not be unreasonably withheld or delayed) and, so long as no Event of
Default has occurred and is continuing, Cinergy (which shall not be unreasonably withheld or delayed); provided that unless such assignment is of the entire right, title and interest of the transferor Bank hereunder, after making any such
assignment such transferor Bank shall have a Commitment of at least $10,000,000 (unless Cinergy and the Administrative Agent shall otherwise agree). Upon execution and delivery of such instrument of assumption and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set
forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrowers shall make appropriate arrangements so that, if required by the Assignee, a Note(s) is issued to the Assignee. If the Assignee is not incorporated under
the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account, deliver to the Borrowers and the Administrative Agent certification as to exemption from
deduction or withholding of any United States federal income taxes in accordance with Section 8.04. All assignments (other than assignments to Affiliates) shall be subject to a transaction fee established by, and payable by the transferor Bank
to, the Administrative Agent for its own account (which shall not exceed $5,000). 
 (d) Any Bank may at any time assign all or any
portion of its rights under this Agreement and its Note (if any) to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder or modify any such obligations. 
 (e) No Assignee, Participant or other transferee of any Bank’s rights (including any Applicable Lending Office other than such Bank’s
initial Applicable Lending Office) shall be entitled to receive any greater payment under Section 8.03 or 8.04 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made by reason of
the provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. 

Section 9.07. Collateral. Each of the Banks represents to the Administrative Agent and each of the other Banks that it in good faith is not relying
upon any “margin stock” (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement. 
  

 26 

 Section 9.08. Confidentiality. Each Agent and each Bank agrees to keep any information delivered or
made available by any Borrower pursuant to this Agreement confidential from anyone other than persons employed or retained by such Bank and its affiliates who are engaged in evaluating, approving, structuring or administering the credit facility
contemplated hereby; provided that nothing herein shall prevent any Bank from disclosing such information (a) to any other Bank or any Agent, (b) to any other Person if reasonably incidental to the administration of the credit
facility contemplated hereby, (c) upon the order of any court or administrative agency, (d) upon the request or demand of any regulatory agency or authority, (e) which had been publicly disclosed other than as a result of a disclosure
by any Agent or any Bank prohibited by this Agreement, (f) in connection with any litigation to which any Agent, any Bank or its subsidiaries or Parent may be a party, (g) to the extent necessary in connection with the exercise of any
remedy hereunder, (h) to such Bank’s or any Agent’s legal counsel and independent auditors and (i) subject to provisions substantially similar to those contained in this Section 9.08, to any actual or proposed Participant or
Assignee. 
 Section 9.09. Governing Law; Submission to Jurisdiction. This Agreement and each Note (if any) shall be construed in accordance
with and governed by the law of the State of New York. Each Borrower hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City
for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each Borrower irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to
the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. 
 Section 9.10. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written,
relating to the subject matter hereof. 
 Section 9.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE AGENTS, THE ISSUING BANKS AND THE
BANKS, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 Section 9.12. USA Patriot Act. Each Bank hereby notifies each Borrower that pursuant to the requirements of the USA Patriot Act, Title
III of Pub. L. 107-56 (signed into law October 26, 2001) (the “Act”), it is required to obtain, verify and record information that identifies such Borrower, which information includes the name and address of such Borrower and
other information that will allow such Bank to identify such Borrower in accordance with the Act.

 Pricing Schedule 
  
 Each of “Euro-Dollar Margin” and “Facility Fee Rate” means, for any date, the rate set forth below in the applicable row and
column corresponding to the column and “Utilization” that exist on such date:

	 Utilization > 50%
	  	24.0	  	28.0	  	32.0	  	40.0	  	52.5	  	65.0

  
 The Euro-Dollar Margin for any
Term Loan shall equal the sum of (i) the rate that would otherwise be in effect based upon the table above and (ii) 12.5 basis points. 
 The
“Utilization” applicable to any date is the percentage equivalent of a fraction the numerator of which is the sum of (i) the aggregate outstanding principal amount of the Loans to all Borrowers determined at such time after
giving effect, if one or more Loans are being made at such time, to any substantially concurrent application of the proceeds thereof to repay one or more other Loans plus (ii) the aggregate amount of the Letter of Credit Liabilities of all
Banks for the account of all Borrowers at such time and the denominator of which is the aggregate amount of the Commitments at such date. If for any reason any Loans or Letter of Credit Liabilities remain outstanding following termination of the
Commitments, Utilization will be deemed to be 100%. 
 The Facility Fee Rate at any date shall be determined on the basis of the credit ratings of
Cinergy at such date, while the Euro-Dollar Margin applicable at any date for purposes of calculating interest on a Loan or fees in respect of a Letter of Credit shall be based upon the credit ratings of the Borrower to which such Loan is
outstanding or for whose account such Letter of Credit was issued. The credit ratings to be utilized for purposes of this Schedule are those indicated for or assigned to the senior unsecured long-term debt securities of the relevant Borrower without
third-party credit enhancement, and any rating indicated for or assigned to any other debt security of such Borrower shall be disregarded. The ratings in effect for any day are those in effect at the close of business on such day. A change in credit
rating will result in an immediate change in the applicable pricing. In the case of split ratings from S&P and Moody’s, the rating to be used to determine the applicable pricing is a rating one notch higher than the lower of the two.

 OPINION OF INTERNAL COUNSEL OF THE BORROWER 
  
 [Effective Date]

 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Barclays Bank PLC 
 as Administrative Agent 
 200 Park Avenue 
 New York, New York
10166 
  
 Ladies and Gentlemen: 
 I am [title of internal counsel] of [Cinergy Corp.] [The Cincinnati Gas & Electric Company] [PSI Energy, Inc.] [The Union Light, Heat and Power Company]
(the “Borrower”) and have acted as its counsel in connection with the Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among Cinergy Corp., The Cincinnati
Gas & Electric Company, PSI Energy, Inc., The Union Light, Heat and Power Company (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”), the banks listed on the
signature pages thereof, Barclays Bank PLC, as Administrative Agent, and JPMorgan Chase Bank, N.A., as Syndication Agent. Capitalized terms defined in the Credit Agreement are used herein as therein defined. This opinion letter is being delivered
pursuant to Section 3.01(b) of the Credit Agreement. 
 In such capacity, I or attorneys under my direct supervision have examined originals or
copies, certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or
advisable for purposes of this opinion. 
 Upon the basis of the foregoing, I am of the opinion that: 
 1. The Borrower is [a Delaware] [an Ohio] [an Indiana] [a Kentucky] corporation, validly existing and in good standing under the laws of [Delaware]
[Ohio] [Indiana] [Kentucky]. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement and any Notes are
within the Borrower’s corporate powers, have been duly authorized by all necessary corporate action, require no action by or in respect of, or filing with, any governmental body, agency or official (except for [list exceptions], which have been
obtained or made, as the case may be, and are in full force and effect) and do not contravene, or constitute a default under, any provision of applicable law or regulation or of the articles of incorporation or by-laws of the Borrower or, to my
knowledge, of any agreement, judgment, injunction, order, decree or other instrument binding upon the Borrower or, to my knowledge, result in the creation or imposition of any Lien on any asset of the Borrower or any of its Material Subsidiaries.

 3. The Credit Agreement and any Notes executed and delivered as of the date hereof have been duly executed and delivered by the
Borrower. 
 4. Except as disclosed in the Borrower’s annual report on Form 10-K for the fiscal year ended December 31, 2005
and its quarterly report on Form 10-Q for the period ended March 31, 2006, to my knowledge (but without independent investigation), there is no action, suit or proceeding pending or threatened against or affecting, the Borrower or any of its
Subsidiaries before any court or arbitrator or any governmental body, agency or official, which would be likely to be decided adversely to the Borrower or such Subsidiary and, as a result, to have a material adverse effect upon the business,
consolidated financial position or consolidated results of operations of the Borrower and its Consolidated Subsidiaries, considered as a whole, or which in any manner draws into question the validity of the Credit Agreement or any Notes. 

The phrase “to my knowledge”, as used in the foregoing opinion, refers to my actual knowledge without any independent investigation as to any such
matters. 
 I am a member of the Bar of the State of [Delaware] [Ohio] [Indiana] [Kentucky] and do not express any opinion herein concerning any law
other than the law of the State of [Delaware] [Ohio] [Indiana] [Kentucky] and the federal law of the United States of America. 
 The opinions expressed
herein are limited to the matters expressly stated herein, and no opinion is to be inferred or may be implied beyond the matters expressly so stated. This opinion is rendered to you in connection with the above-referenced matter and may not be
relied upon by you for any other purpose, or relied upon by, or furnished to, any other Person, firm or corporation without my prior written consent, except for Additional Banks and Assignees. My opinions expressed herein are as of the date hereof,
and I undertake no obligation to advise you of any changes of applicable law or any other matters that may come to my attention after the date hereof that may affect my opinions expressed herein. 
  
 Very truly yours, 

 EXHIBIT B-2 
 OPINION OF 
 ROBINSON, BRADSHAW & HINSON, P.A., 
 SPECIAL COUNSEL FOR THE BORROWER 
  
 [Effective Date] 
 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Barclays Bank PLC 
       as Administrative Agent 
 200 Park Avenue 
 New York, New York 10166 
  
 Ladies and Gentlemen: 
 We have acted as counsel to [Cinergy Corp., a Delaware] [The Cincinnati Gas & Electric Company, an Ohio] [PSI Energy, Inc., an Indiana] [The Union Light,
Heat and Power Company, a Kentucky] corporation (the “Borrower”), in connection with the Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among Cinergy Corp., The
Cincinnati Gas & Electric Company, PSI Energy, Inc., The Union Light, Heat and Power Company (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”), the banks
listed on the signature pages thereof, Barclays Bank PLC, as Administrative Agent, and JPMorgan Chase Bank, N.A., as Syndication Agent. Capitalized terms used herein and not defined shall have the meanings given to them in the Credit Agreement. This
opinion letter is being delivered pursuant to Section 3.01(b) of the Credit Agreement. 
 In connection with this opinion, we also examined
originals, or copies identified to our satisfaction, of such other documents and considered such matters of law and fact as we, in our professional judgment, have deemed appropriate to render the opinions contained herein. Where we have considered
it appropriate, as to certain facts we have relied, without investigation or analysis of any underlying data contained therein, upon certificates or other comparable documents of public officials and officers or other appropriate representatives of
the Borrower. 
 In rendering the opinions contained herein, we have assumed, among other things, that the Credit Agreement and any Notes to be executed
(i) are within the Borrower’s corporate powers, (ii) have been duly authorized by all necessary corporate action, (iii) have been duly executed and delivered, (iv) require no action by or in respect of, or filing with, any
governmental body, agency of official and (v) do not contravene, or constitute a default under, any provision of applicable law or regulation or of the Borrower’s certificate of incorporation or by-laws or any agreement, judgment,
injunction, order, decree or other instrument binding upon the Borrower or result in the creation or imposition of any Lien on any asset of the Borrower. In addition, we have assumed that the Credit Agreement fully states the agreement between the
Borrower and the Banks with respect to the matters addressed therein, and that the Credit Agreement constitutes a legal, valid and binding obligation of each Bank, enforceable in accordance with its respective terms. 
 The opinions set forth herein are limited to matters governed by the laws of the State of North Carolina and the federal laws of the United States, and no opinion
is expressed herein as to the laws of any other jurisdiction. For purposes of our opinions, we have disregarded the choice of law provisions in the Credit Agreement and, instead, have assumed with your permission that the Credit Agreement and the
Notes are governed exclusively by the internal, substantive laws and judicial interpretations of the State of North Carolina. We express no opinion concerning any matter respecting or affected by any laws other than laws that a lawyer in North
Carolina exercising customary professional diligence would reasonably recognize as being directly applicable to the Borrower, the Loans, or any of them. 
 Based upon and subject to the foregoing and the further limitations and qualifications hereinafter expressed, it is our opinion that the Credit Agreement constitutes the legal, valid and binding obligation of the Borrower and the Notes, if
and when issued, will constitute legal, valid and binding obligations of the Borrower, in each case, enforceable against the Borrower in accordance with its terms. 
 The opinions expressed above are subject to the following qualifications and limitations: 
 1. Enforcement of the
Credit Agreement and the Notes is subject to the effect of applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and similar laws affecting the enforcement of creditors’ rights generally. 
 2. Enforcement of the Credit Agreement and the Notes is subject to the effect of general principles of equity (regardless of whether considered in a
proceeding in equity or at law) by which a court with proper jurisdiction may deny rights of specific performance, injunction, self-help, possessory remedies or other remedies. 
 3. We do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement or any Note that (i) purport to
excuse a party for liability for its own acts, (ii) purport to make void any act done in contravention thereof, (iii) purport to authorize a party to act in its sole discretion, (iv) require waivers or amendments to be made only in
writing, (v) purport to effect waivers of constitutional, statutory or equitable rights or the effect of applicable laws, (vi) impose liquidated damages, penalties or forfeiture, or (vii) purport to indemnify a party for its own
negligence or willful misconduct. Indemnification provisions in the Credit Agreement are subject to and may be rendered unenforceable by applicable law or public policy, including applicable securities law. 

 4. We do not express any opinion as to the enforceability of any provisions contained in the Credit
Agreement or the Notes purporting to require a party thereto to pay or reimburse attorneys’ fees incurred by another party, or to indemnify another party therefor, which may be limited by applicable statutes and decisions relating to the
collection and award of attorneys’ fees, including but not limited to North Carolina General Statutes § 6-21.2. 
 5. We
do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement purporting to waive the right of jury trial. Under North Carolina General Statutes § 22B-10, a provision for the waiver of the right to
a jury trial is unconscionable and unenforceable. 
 6. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement concerning choice of forum or consent to the jurisdiction of courts, venue of actions or means of service of process. 
 7. It is likely that North Carolina courts will enforce the provisions of the Credit Agreement providing for interest at a higher rate resulting from a Default or Event of Default (a “Default Rate”) which
rate is higher than the rate otherwise stipulated in the Credit Agreement. The law, however, disfavors penalties, and it is possible that interest at the Default Rate may be held to be an unenforceable penalty, to the extent such rate exceeds the
rate applicable prior to a default under the Credit Agreement. Also, since North Carolina General Statutes § 24-10.1 expressly provides for late charges, it is possible that North Carolina courts, when faced specifically with the issue,
might rule that this statutory late charge preempts any other charge (such as default interest) by a bank for delinquent payments. The only North Carolina case which we have found that addresses this issue is a 1978 Court of Appeals decision, which
in our opinion is of limited precedential value, North Carolina National Bank v. Burnette, 38 N.C. App. 120, 247 S.E.2d 648 (1978), rev’d on other grounds, 297 N.C. 524, 256 S.E.2d 388 (1979). While the court in that case did
allow interest after default (commencing with the date requested in the complaint) at a rate six percent in excess of pre-default interest, we are unable to determine from the opinion that any question was raised as to this being penal in nature,
nor does the court address the possible question of the statutory late charge preempting a default interest surcharge. Therefore, since the North Carolina Supreme Court has not ruled in a properly presented case raising issues of its possible penal
nature and those of North Carolina General Statutes § 24-10.1, we are unwilling to express an unqualified opinion that the Default Rate of interest prescribed in the Credit Agreement is enforceable. 
 8. We do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement relating to evidentiary standards or
other standards by which the Credit Agreement are to be construed. 
 This opinion letter is delivered solely for your benefit in connection with the
Credit Agreement and, except for any Additional Bank or any Assignee which becomes a Bank pursuant to Section 2.17 or 9.06(c) of the Credit Agreement, may not be used or relied upon by any other Person or for any other purpose without our prior
written consent in each instance. Our opinions expressed herein are as of the date hereof, and we undertake no obligation to advise you of any changes of applicable law or any other matters that may come to our attention after the date hereof that
may affect our opinions expressed herein. 
  
 Very truly
yours,

 To the Banks and the Administrative Agent 
   Referred to Below

 c/o Barclays Bank PLC, 
 as Administrative Agent 
 200 Park Avenue 
 New York, New York 10166 
  
 Dear Sirs: 
 We have participated in the preparation of the Amended and Restated Credit Agreement (the “Credit Agreement”) dated as of June 29, 2006 among Cinergy Corp., a Delaware corporation, The Cincinnati Gas &
Electric Company, an Ohio corporation, PSI Energy, Inc., an Indiana corporation, The Union Light, Heat and Power Company, a Kentucky corporation (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the
“Borrowers”, each individually, a “Borrower”), the banks listed on the signature pages thereof (the “Banks”), Barclays Bank PLC, as Administrative Agent (the “Administrative
Agent”), and JPMorgan Chase Bank, N.A., as Syndication Agent, and have acted as special counsel for the Agents for the purpose of rendering this opinion pursuant to Section 3.01(c) of the Credit Agreement. Terms defined in the Credit
Agreement are used herein as therein defined. 
 We have examined originals or copies, certified or otherwise identified to our satisfaction, of such
documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion. 
 Upon the basis of the foregoing, we are of the opinion that: 
 1. The execution, delivery and performance by each Borrower of the Credit Agreement and the Notes are within such Borrower’s corporate powers and have been duly authorized by all necessary corporate action. 
 2. The Credit Agreement constitutes a valid and binding agreement of each Borrower and the Notes, if and when issued by a Borrower, constitute valid
and binding obligations of such Borrower enforceable in accordance with their respective terms, except as the same may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally and by general principles of
equity. 
 In giving the foregoing opinion, (i) we express no opinion as to the effect (if any) of any law of any jurisdiction (except the State of
New York) in which any Bank is located which limits the rate of interest that such Bank may charge or collect and (ii) we have relied, without independent investigation, as to all matters governed by the laws of each of Delaware, Ohio, Indiana
and Kentucky upon the opinion of the internal counsel of the Borrower located in such jurisdiction, dated [Effective Date], a copy of each of which has been delivered to you. 
 This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or
furnished to any other person, firm or corporation without our prior written consent, except for Additional Banks and all Participants. 
  
 Very truly yours,

(together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”, each individually, a “Borrower”), the Assignor and the other Banks party thereto, as Banks, the
Administrative Agent and JPMorgan Chase Bank, N.A., as Syndication Agent (the “Credit Agreement”); 
 WHEREAS, as provided under the
Credit Agreement, the Assignor has a Commitment to make Loans to the Borrowers and participate in Letters of Credit in an aggregate principal amount at any time outstanding not to exceed

 WHEREAS, Loans made to the Borrowers by the Assignor under the

 WHEREAS, the Assignor proposes to assign to the Assignee all of the rights of the Assignor under the Credit Agreement in respect of a portion of its Commitment
thereunder in an amount equal to $            (the “Assigned Amount”), together with a corresponding portion of its outstanding Loans and Letter of Credit Liabilities, and
the Assignee proposes to accept assignment of such rights and assume the corresponding obligations from the Assignor on such terms;* 
 NOW, THEREFORE,
in consideration of the foregoing and the mutual agreements contained herein, the parties hereto agree as follows: 
 SECTION 1.
Definitions. All capitalized terms not otherwise defined herein shall have the respective meanings set forth in the Credit Agreement. 
 SECTION 2. Assignment. The Assignor hereby assigns and sells to the Assignee all of the rights of the Assignor under the Credit Agreement to the extent of the Assigned Amount, and the Assignee hereby accepts such
assignment from the Assignor and assumes all of the obligations of the Assignor under the Credit Agreement to the extent of the Assigned Amount, including the purchase from the Assignor of the corresponding portion of the principal amount of the
Loans made by, and Letter of Credit Liabilities of, the Assignor outstanding at the date hereof. Upon the execution and delivery hereof by the Assignor, the Assignee [, Cinergy Corp.] [, the Issuing Banks] and the Administrative Agent, the payment
of the amounts specified in Section 3 required to be paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed to the rights and be obligated to perform the obligations of a Bank under the Credit Agreement with a
Commitment in an amount equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by a like amount and the Assignor released from its obligations under the Credit Agreement to the extent such
obligations have been assumed by the Assignee. The assignment provided for herein shall be without recourse to the Assignor. 
 SECTION 3. Payments. As consideration for the assignment and sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the date hereof in Federal funds the amount heretofore agreed
between them.2 It is understood that facility [and Letter of Credit] fees accrued to the date hereof in respect of the Assigned Amount are for the account of the Assignor and such fees accruing from and including the date
hereof are for the account of the Assignee. Each of the Assignor and the Assignee hereby agrees that if it receives any amount under the Credit Agreement which is for the account of the other party hereto, it shall receive the same for the account
of such other party to the extent of such other party’s interest therein and shall promptly pay the same to such other party. 
 SECTION 4. Consent to Assignment. This Agreement is conditioned upon the consent of [Cinergy Corp.,] [the Issuing Banks] and the Administrative Agent pursuant to Section 9.06(c) of the Credit Agreement. The
execution of this Agreement by [Cinergy Corp.,] [the Issuing Banks] and the Administrative Agent is evidence of this consent. Pursuant to Section 9.06(c) each Borrower agrees to execute and deliver a Note, if required by the Assignee, payable
to the order of the Assignee to evidence the assignment and assumption provided for herein. 
 SECTION 5. Non-reliance on
Assignor. The Assignor makes no representation or warranty in connection with, and shall have no responsibility with respect to, the solvency, financial condition, or statements of any Borrower, or the validity and enforceability of the
obligations of any Borrower in respect of the Credit Agreement or any Note. The Assignee acknowledges that it has, independently and without reliance on the Assignor, and based on such documents and information as it has deemed appropriate, made its
own credit 

  

	1	The asterisked provisions shall be appropriately revised in the event of an assignment after the Commitment Termination Date. 

	2	Amount should combine principal together with accrued interest and breakage compensation, if any, to be paid by the Assignee. It may be preferable in an appropriate case to specify these
amounts generically or by formula rather than as a fixed sum. 

 
analysis and decision to enter into this Agreement and will continue to be responsible for making its own independent appraisal of the business, affairs and financial
condition of each Borrower. 
 SECTION 6. Governing Law. This Agreement shall be governed by and construed in accordance with
the laws of the State of New York. 
 SECTION 7. Counterparts. This Agreement may be signed in any number of counterparts,
