 4.4 Tracking Account. 
  
 (a) Seller shall maintain an account (the “Tracking Account”), as provided in this Section 4.4. As of the Effective Date,
the balance of the Tracking Account shall be an amount equal to the sum of (i) four hundred and eight million, seven hundred and fifty-nine thousand, nine hundred and sixteen dollars and seventy-one cents ($408,759,916.71) (which represents the

existed immediately prior so the Tenth Amendment. Within thirty (30) days after the Effective Date, Seller shall provide Buyer with Seller’s calculation of the Effective Date balance of the Tracking Account, together with supporting
documentation therefor. If Buyer and Seller are unable to agree on the Effective Date balance of the Tracking Account within twenty (20) days of receipt by Buyer of Seller’s calculation, the Effective Date balance of the Tracking Account shall
be determined by a nationally recognized independent accounting firm mutually acceptable to the parties, the fees of which shall be shared equally between Buyer and Seller. Seller and Buyer agree that the Effective Date balance of the Tracking
Account as finally determined hereunder (the “Outstanding Balance”) shall be deemed to be a loan by Seller to Buyer in a principal amount equal to the Outstanding Balance (the “Tracking Account Loan”).
Notwithstanding any limitations on recourse in any Project Document to the contrary, but subject to all terms and conditions of subordination (including with respect to the Collateral) set forth in the Intercreditor Agreement, Buyer hereby waives
any such limitations on recourse applicable to it with respect to its obligations hereunder, and agrees that is shall be personally liable (on a recourse basis) for the repayment of the Tracking Account Loan and any accrued and unpaid interest
thereon pursuant to this Agreement. Repayment of the Tracking Account Loan shall be made in accordance with this Section 4.4. 
  
 (b) [Reserved]. 
  
 (c) Interest shall accrue on the unpaid balance of the Tracking Account Loan for the period commencing on the Effective Date until the
Tracking Account Loan shall 
  

 5 

 have been paid in full, at the Interest Rate, calculated on the basis of the actual number of Days
elapsed divided by 365. From the Effective Date to but excluding June 1, 2015, but subject to the provisions of Section 4.7, interest (i) shall be due and payable on each June 1 and December 1, commencing on December 1, 2001 (each such date, an
“Interest Payment Date”) in an amount equal to the interest accrued and unpaid on the Tracking Account Loan (including interest accrued on any deferred interest) as of such date and (ii) may be prepaid, at Buyer’s option, on
any Business Day on which any payments may be made to Buyer’s equity investors under the Indenture, in an amount equal to the lesser of (A) the interest accrued on the unpaid balance of the Tracking Account Loan (including interest accrued on
any deferred interest) as of such date, and (B) the amount available to be distributed to Buyer’s equity investors pursuant to the Indenture on such date. Commencing on June 1, 2015 and continuing on the first day of each December and June
thereafter until December 1, 2034 (or until the Tracking Account Loan has been paid in full), but subject to Section 4.7, the Tracking Account Loan shall be payable in forty (40) equal semi-annual installments of principal and interest, each such
installment to be in such amount as is necessary to filly amortize the Tracking Account Loan over the period from and including June 1, 2015 to but excluding December 1, 2034. Each of Buyer and Seller shall use its reasonable efforts to prepare and
attach to the Tenth Amendment, within thirty (30) days of the final determination of the Effective Date, the balance of the Tracking Account pursuant to Section 4.4(a) and a schedule reflecting the payments required under the Tracking Account Loan
pursuant to the immediately preceding sentence. Interest which is not paid as of the due date therefor shall not be capitalized into the principal amount of the Tracking Account Loan, but shall be carried by Buyer as a separate obligation on its
books and records, provided that if any payment of interest is not made as of the due date, interest shall accrue on the amount of interest that Buyer has so failed to make payment as the Interest Rate (if Buyer was unable to make such payment
pursuant to Section 4.7) or at the Default Interest Rate (in all other circumstances) for the period from such due date until the date upon which such payment is made in full. Buyer may, at any time after the date hereof and from time to time,
prepay all or any portion of accrued but unpaid interest and/or the unpaid balance of the Tracking Account Loan, without penalty or premium. If (i) a Termination Date occurs pursuant to Section 8.1 hereof, the entire principal amount of the Tracking
Account Loan outstanding, and all interest accrued and unpaid thereon, shall be accelerated and shall become immediately due and payable without any further presentment, demand, protest or further notice of any kind or (ii) the Facility Lenders
declare the Senior Obligations to be due and payable prior to the scheduled maturity thereof and the Facility Lenders shall commence any judicial, non-judicial or other proceeding to foreclose or to realize against any of their liens or security
interests on the Facility (including through a deed or other transfer in lieu of foreclosure on the Facility), then Seller, by notice to Buyer, may declare the unpaid balance of the Tracking Account Loan accelerated, whereupon the entire principal
amount of the Tracking Account Loan outstanding, and all interest accrued and unpaid thereon, shall, upon Buyer’s receipt of such notice, be accelerated and shall become immediately due and payable without any further presentment, demand,
protest or further notice of any kind, and Buyer shall pay the amount due, determined as of the date of such notice (including any interest accrued thereon until the date of payment), to Seller; provided, however, that, in the case of clause (ii) of
this sentence, if 
  

 6 

 the Senior Obligations shall no longer be due and payable prior to the scheduled maturity thereof or if
the Facility Lenders shall no longer be seeking to succeed to Buyer’s interest in the Facility (whether through foreclosure or by delivery of a deed or other transfer of the ownership of the Facility in lieu of foreclosure), or, in the case of
clause (i) or (ii) of this sentence, if the Facility Lenders or their designee(s) or assignee(s) shall succeed to Buyer’s interest under this Agreement in the manner contemplated by the Intercreditor Agreement, then such payment shall no longer
be due and payable under this Section 4.4(c) until a due date for such payment occurs thereafter, and if Buyer shall have theretofore made payment of all or any portion of the Tracking Account Loan or any interest thereon in accordance with clause
(i) or clause (ii) of this sentence or if Seller shall have theretofore obtained any portion of any such payment, whether through foreclosure or otherwise, Seller shall refund any such payment or recovery to Buyer. Notwithstanding any other
provision contained herein, but subject to the Intercreditor Agreement, Seller’s sole remedy for Buyer’s failure so make payment to Seller in accordance with clause (ii) of the immediately preceding sentence of this Section 4.4(c) shall be
to foreclose on any collateral securing such payment. 
  
 (d) At the written request of Seller at any time after the occurrence of a Buyer Event of Default pursuant to Section 8.1(a) or, in the case of any other Buyer Event of Default, on or after any Termination Date in respect thereof, Buyer
agrees that is will immediately and irrevocably certify to the Trustee, pursuant to Section 4.14(b) of the Indenture that all principal and interest payments due in accordance with this Section 4.4 constitute amounts payable to Seller as the
“Fuel Supplier” as contemplated by Section 4.14(b) of the Indenture. By its execution of this Agreement, Buyer irrevocably constitutes and appoints Seller as Buyer’s “Authorized Representative” (as such term is defined in
the Indenture), with full power and authority in Buyer’s name, place and stead, so execute, acknowledge and deliver to the Trustee any certificate as may be required to be furnished to the Trustee in accordance with Section 4.14(b) of the
Indenture; provided that Seller agrees that is shall only exercise such power and authority under the circumstances described in, and for the purpose of effectuating, the provisions of the immediately preceding sentence. The foregoing grant
of authority (i) to act as Buyer’s “Authorized Representative” under the Indenture is coupled with an interest in favor of Seller and as such shall be irrevocable and shall survive the merger, dissolution or other termination of
Buyer’s existence, (ii) may be exercised by a facsimile signature of the Seller, and (iii) shall survive the assignment by Buyer of this Agreement. If any payment under this Agreement shall be due on a Day which is not a Business Day, such
payment shall be made without default on the next succeeding Business Day. Any payments made pursuant to this Article 4 shall be made by wire transfer in immediately available funds for credit to Seller’s account at Bank of America, N.A.,
Houston, Texas, ABA No. 111000012, Account No. 3750494099, or as Seller may specify by notice to Buyer on or before the second Business Day prior to payment. 
  

(e) All payments received by Seller under this Agreement, shall be applied first to the payment of accrued and unpaid interest; and
then to principal, with any prepayments of principal to be applied so the installments of the principal of the Tracking Account Loan in inverse order of maturity.

 4.5 [Reserved]. 
  

4.6 [Reserved]. 
  
 4.7 Deferral of Certain Payments. For as long as the Senior Obligations are outstanding, notwithstanding the provisions of Section 4.4,
payment of amounts otherwise due under Section 4.4 shall be deferred if and so the extent Buyer’s agreements with the Facility Lenders in connection with the Senior Obligations prohibit payment of like amounts to Buyer’s equity investors
until such time as such payments to Buyer’s equity investors could be made under such agreements (and Buyer agrees not to make payment to its equity investors during such deferral). For as long as the ConEd Subordinated Obligations are
outstanding, notwithstanding the provisions of Section 4.4 hereof, if and to the extent that Buyer can make payments to its equity investors, all amounts which could be paid to Buyer’s equity investors by Buyer shall be applied first to pay any
and all amounts due and payable under the ConEd Subordinated Obligations, and second to pay all amounts due and payable under Section 4.4 hereof, and any additional amounts due under Section 4.4 hereof and not paid shall be deferred; provided,
further, that Buyer shall not, on any Business Day on which any payments may be made to Buyer’s equity investors under the Indenture, make any payments to its equity investors of amounts which could be paid to its equity investors unless and
until Buyer shall have paid (i) first, all amounts due and payable under the ConEd Subordinated Obligations; (ii) second, all amounts due and payable under Section 4.4 hereof (including accrued interest thereon) which have previously been deferred
pursuant so this Section 4.7; (iii) third, all principal, accrued interest and all other amounts otherwise due and payable on such Business Day under Section 4.4 hereof; and (iv) fourth, if such Business Day is not an Interest Payment Date, all
accrued and unpaid interest under Section 4.4 hereof as of such Business Day. The provisions of this Section 4.7, however, shall not limit the ability of Seller to exercise its rights to accelerate the Tracking Account Loan or to foreclose on any
collateral securing payment of amounts due under Section 4.4(c) when due as therein provided. Notwithstanding anything contained herein, if and to the extent that Buyer is required to defer payment of any amount due under Section 4.4 in accordance
with this Section 4.7, Buyer’s failure to make any such payment shall not constitute or result in a Buyer Event of Default under this Agreement. Buyer and Seller expressly acknowledge and agree that the obligation of Buyer to pay the principal
amount of the Tracking Account Loan and accrued interest thereon when due and payable in accordance with the provisions of Section 4.4, shall constitute Tracking Account Liabilities for purposes of the Intercreditor Agreement and shall be subject
to, and shall be payable when and as permitted by, the provisions of Section 3(b) of the Intercreditor Agreement.

Effect; Assignment; No Third Party Beneficiary. Subject to the remaining provisions of this Section 10.2, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted
assigns. No party may assign any rights or obligations under this Agreement without the prior written consent of the 
  

 15 

 other party or parties; provided, however, that Seller may assign its rights to receive payments hereunder and Seller
acknowledges that Buyer has pledged its interests hereunder with the consent of the Seller to the Facility Lenders; and provided, further, that as long as the Parent Guaranty is in effect and Parent shall have confirmed in writing to Buyer and the
Facility Lenders, in a manner and in form and substance reasonably satisfactory to Buyer and the Facility Lenders, the continuing validity and enforceability of the Parent Guaranty, Seller may assign this Agreement to any Person and thereby be
relieved of its obligations hereunder. If Buyer does assign its rights under this Agreement, the expression “Buyer” as used herein and in the exhibits attached hereto shall be deemed to refer to Buyer’s assignee. The parties
acknowledge and agree that any assignment by any party of any rights or obligations hereunder shall not in any way release such party from any obligations so assigned. Nothing expressed or implied in this Agreement is intended to confer on any
Person other than Buyer, Seller and their successors and permitted assigns, any rights or obligations under this Agreement. 
  
 10.3 Incidental Expenses; Brokers. Except as expressly provided otherwise herein, each party hereto shall bear and pay its own expenses of
negotiating and consummating the transactions contemplated by this Agreement, and any broker’s or other commissions that may be due as a result of any agreement made by the party. 
  
 10.4 Multiple Counterparts. This Agreement may be executed in multiple counterparts, each of which may be
signed by fewer than all parties hereto, but all of which shall be considered one instrument for all purposes. 
  
 10.5 Entire Agreement. This Agreement and the other documents, if any, to be delivered pursuant hereto constitute the entire agreement
between the parties and supersede any prior or contemporaneous written or oral agreement or understanding between the parties with respect to the subject matter of this Agreement. The execution and delivery of any other documents contemplated to be
executed and delivered hereunder shall not supersede or otherwise affect the provisions of this Agreement. 
  
 10.6 Applicable Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK, EXCLUDING
CONFLICT-OF-LAWS RULES (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW). EACH OF BUYER AND SELLER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDINGS
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER AGREEMENTS REFERRED TO HEREIN OR ANY OF TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. 
  
 10.7 Amendment. No amendment or modification of this Agreement shall be effective unless same is in writing and signed by the parties
affected by such amendment or modification. 
  
 10.8
Waiver. No waiver of any provision of or rights under this Agreement shall be effective unless in writing and signed by the waiving party. No waiver of any specified right or provision shall be construed as a waiver of any other right
or provision or as a continuing waiver. 
  

 16 

 10.9 Severability. If any term or other provision of this Agreement is invalid, illegal, or
incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall to the fullest extent permitted by law nevertheless remain in full force and effect. Upon such determination that any term
or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement to effect the original intent of the parties as closely as possible in an acceptable manner so that the
transactions contemplated hereby are fulfilled to the extent possible. 
  
 10.10 [Reserved].

Seller and Buyer will cooperate with each other in the development and distribution of all news releases and other public disclosures relating to the transactions contemplated hereby. Neither Seller nor Buyer shall issue or make, or cause to have

 10.12 Preparation. This Agreement was negotiated and
prepared by both parties hereto with advice of counsel to the extent deemed necessary by each party, was not prepared by any party to the exclusion of the other, and accordingly, should not be construed against either party by reason of its
preparation. 
  
 12. The parties agree that Exhibit 2.2, Exhibit
4.2, Exhibit 4.6, Exhibit 4.6(d), Exhibit 7.2(e)(i) and Exhibit 7.2(e)(ii) of the Original Agreement shall be deleted in their entirety. The parties further agree that Annex “A” and the Schedule A referred to therein, which were

 13. This Amendment shall be effective as of 8:00 a.m. (Central time) on June

enter into this Amendment, represents and warrants to the other Party that: 
  
 (a) Organization. Each party is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and is qualified to do business in all jurisdictions in which the
nature of business conducted by it makes such qualification necessary and where failure so to qualify would preclude its ability to perform its obligations under this Amendment. 
  
 (b) Authorization and Validity. This Amendment and the transactions contemplated hereby have been
duly authorized by such party, and this Amendment has been duly executed and delivered by such party and constitutes the legal, valid and binding obligation of such party, enforceable against such party in accordance with its terms, subject,
however, to applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting creditors’ rights generally and except as the enforceability thereof may be limited by general principles of equity (regardless of whether
considered in a proceeding in equity or at law). 
  

 17 

 (c) No Violation. The execution and delivery of this Amendment by such party and
the performance by such party of this Amendment and the transactions contemplated hereby, do not and will not (i) violate or conflict with any provision of such party’s partnership agreement, certificate of incorporation or by-laws, as the case
may be, (ii) violate any existing statute or law or any judgment, decree, order, regulation or rule of any court or governmental authority applicable to such party, which violation will have a material and adverse effect on such party’s ability
to perform its obligations under this Amendment or (iii) under existing law require any consent, approval or authorization of, or designation, declaration or filing with, any governmental authority on the part of such party. 
  
 (d) Legal Proceedings. There are no judicial or
administrative actions, proceedings, or to such party’s knowledge, investigations (including, without limitation, bankruptcy, reorganization or insolvency actions, proceedings or investigations) pending or, to such party’s knowledge,
threatened that (i) challenge the validity of this Amendment or the transactions contemplated hereby or (ii) seek to restrain or prevent any action taken or to be taken by such party in connection with this Amendment would have a material and
adverse effect on such party’s ability to perform its obligations under this Amendment. 
  
 15. Except as specifically amended herein, the Original Agreement, as amended by this Amendment, shall continue to be in full force and effect and is hereby ratified by Seller and Buyer. 
  
 16. This Amendment may be executed in multiple counterparts, each of which
may be signed by fewer than all parties hereto, but all of which shall be considered one instrument for all purposes. This Amendment was negotiated and prepared by all parties hereto with the advice of counsel to the extent deemed necessary by each
party, was not prepared by any party to the exclusion of the other parties, and accordingly, should not be construed against any party by reason of its preparation. 
  

 18

Kendall’s metering devices under this Section 9.4, and Kendall and Seller cannot agree on the amount of the adjustment necessary to correct the measurements made by such inaccurate or defective Seller’s back-up metering devices, Kendall
and Seller shall, as soon as practicable and on the basis of procedures to be mutually agreed by Kendall and Seller, estimate the amount of the necessary adjustment on the basis of deliveries of the Net Electrical Output of the Dedicated Units to
the Commonwealth Edison System during periods of similar operating conditions (e.g., based on the Fuel use records for the Dedicated Units) when Kendall’s metering devices were registering accurately. Where Seller is required to
“agree” on a matter with Kendall pursuant to this Section 9.4(a), Purchaser shall direct Seller what position to take in such matter and Seller shall use Commercially Reasonable Efforts to advance Purchaser’s directives; 

 
 (b) In the event that Kendall and Seller cannot agree on the actual
period during which the inaccurate measurements were made, the period during which the measurements are to be adjusted shall be the shorter of (i) one half of the period from the last test of the relevant metering devices, and (ii) the 180 Days
immediately preceding the test that found the relevant metering devices to be defective or inaccurate. Where Seller is 

  

 22 

 
required to “agree” on a matter with Kendall pursuant to this Section 9.4(b), Purchaser shall direct Seller what position to take in such matter
and Seller shall use Commercially Reasonable Efforts to advance Purchaser’s directives; and 
  
 (c) To the extent that the adjustment period covers a period of deliveries for which payment has already been made by Purchaser, Seller shall use the
corrected measurements as determined in accordance with this Section 9.4 to re-compute the amount due for the period of the inaccuracy and shall subtract the previous payments by Purchaser for such period from such re-computed amount. If the
difference is a positive number, such difference shall be paid by Purchaser to Seller and if the difference is a negative number, such difference shall be paid by Seller to Purchaser. Payment of such difference shall be made by means of a credit or
an additional charge on the next statement rendered pursuant to Section 13.1(a). 
  
 (d) For Fuel, the adjustment will be based on gas quantities specified on statements from the Transporting Pipelines delivery of Fuel for the Dedicated Units.

or by-laws of Purchaser, 
  
 (iii) result in a breach of or
constitute a default under any agreement relating to the management or affairs of Purchaser or any indenture or loan or credit agreement or any other agreement, lease, or instrument to which Purchaser is a party or by which Purchaser or its
properties or assets may be bound, the breach or default of which could reasonably be expected to have a material adverse effect on the ability of Purchaser to perform its obligations under this Agreement, or 
  
 (iv) result in, or require, the creation or imposition of any mortgage, deed
of trust, pledge, lien, security interest, or other charge or encumbrance of any nature (other than as may be contemplated by this Agreement) upon or with respect to any of the assets or properties of Purchaser, the creation or imposition of which
could reasonably be expected to have a material adverse effect on the ability of Purchaser to perform its obligations under this Agreement. 
  
 (d) This Agreement constitutes a legal, valid and binding obligation of Purchaser and is enforceable against Purchaser in accordance with its terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights of creditors generally and except as the enforceability of this Agreement is subject to the application of
general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of
materiality, reasonableness, good faith and fair dealing. 
  
 (e)
There is no pending or, to the best of Purchaser’s knowledge, threatened action or proceeding affecting Purchaser before any court, Governmental Agency or arbitrator that could reasonably be expected to materially and adversely affect the
financial condition or operations of Purchaser or the ability of Purchaser to perform its obligations hereunder, or that purports to affect the legality, validity or enforceability of this Agreement. 
  
 Section 14.3 Certificates and Opinions. Each of Purchaser and Seller
shall, upon the request of the other Party, deliver or cause to be delivered from time to time to the other Party certifications of its officers, accountants, engineers or agents as to such matters as either Party may reasonably request in
connection with such Parties’ obligations under this Agreement. 
  
 Section 14.4 Books and Records; Information. Each of Purchaser and Seller shall keep proper books of record and account, in which full and correct entries shall be made of all dealings or transactions of or in relation to its
business and affairs in accordance with GAAP consistently applied. 
  
 Section 14.5 Guarantee. Subject to Section 14.8, Purchaser’s obligations under this agreement shall be guaranteed by Constellation Energy Group, Inc. through a Guarantee in the form of Appendix G. 
  
 Section 14.6 Amendments to Kendall PPA. Seller acknowledges and
agrees that without Purchaser’s prior written consent, Seller shall have no right to agree to or otherwise enter into any amendment or modification to the Kendall PPA which would materially adversely affect Purchaser’s rights and
obligations under this Agreement or, assuming the conditions precedent to the effectiveness of the Assignment and Assumption Agreement were satisfied, Purchaser’s rights and obligations as purchaser under the Kendall PPA, and Seller agrees to
indemnify and hold harmless Purchaser from and against any loss, damage, cost or expense in connection with any unauthorized amendment or modifications to the Kendall PPA. Seller may amend or modify the Kendall PPA to the extent such assignment or
modification is not otherwise prohibited by this Section 14.6. 
  
 Section 14.7 Enforcement of Seller’s Rights under the Kendall PPA. If at any time during the Term Kendall is in breach of its obligations under the Kendall PPA as such event is referenced therein, Seller shall communicate such
to Purchaser in accordance with the terms of Section 14.9. Within five (5) Business Days after Seller’s notice, representatives of the Parties shall discuss what course of action, if any, should be taken with respect to such breach subject to
the provisions below; provided, however, that Purchaser shall have the right to decide on 

  

 31 

 
the course of action to be taken, subject to satisfaction of the conditions to taking such action set forth in this Section 14.7. Following such discussion,
Purchaser may request that Seller enforce its contractual rights under the Kendall PPA (an “Enforcement Action”). Upon receipt of such notice, Seller shall exercise Commercially Reasonable Efforts to enforce such rights. If
Purchaser determines in good faith that it desires that Seller take an Enforcement Action in addition to those that Seller deems to constitute Commercially Reasonable Efforts, it shall notify Seller of the same, and shall specify in writing the
specific actions it desires Seller to take (the “Additional Enforcement Action”). Seller agrees to take an Enforcement Action requested by Purchaser if: (a) it reasonably believes that (i) the actions requested of it are rights that
it is lawfully permitted to take in the enforcement of its rights under the Kendall PPA, and (ii) taking the actions requested will not materially and adversely affect other rights that Seller may have under the Kendall PPA (taking into account to
extent to which Seller has provided the benefit of such rights to Purchaser pursuant to this Agreement); and (b) in the case of an Additional Enforcement Action, to the extent permitted by Section 19.3(d) the Purchaser agrees to pay for any costs
and expenses reasonably incurred by Seller in taking the Additional Enforcement Action which exceed the costs and expenses of Seller taking Commercially Reasonable Efforts, which shall include reasonable compensation for the value of the material
amounts of time which may be required to be expended by Seller’s personnel to take the Additional Enforcement Action. Notwithstanding anything in this Section 14.7 to the contrary, however, Purchaser’s agreement to compensate Seller for
costs and expenses incurred in taking the Additional Enforcement Action under clause (b) above shall not preclude Purchaser from claiming that such Additional Enforcement Action did not require Seller to take actions beyond Commercially Reasonable
Efforts and seeking reimbursement from Seller for the amounts paid to Seller pursuant to such clause (b) under the other provisions of this Agreement, as well as interest thereon pursuant to Section 13.5. 
  
 Section 14.8 Purchaser’s Credit Requirement. If at any time on
or after March 1, 2005, the Credit Rating of Purchaser’s Guarantor is below either BBB- from S&P or Baa3 from Moody’s, Purchaser shall be required to post the Collateral Amount of Performance Assurance with Seller no later than
5:00 pm Central Prevailing Time on the Business Day which is two (2) Business Days after Purchaser’s receipt of Seller’s invoice for such Collateral Amount (“Delivery Date”). Upon delivery of the Performance Assurance,
Seller shall release the Guarantee described in Section 14.5, and Seller shall return such Guarantee to Purchaser within five (5) Business Days of Seller’s receipt of Purchaser’s written request therefor. The Performance Assurance shall be
held by Seller until the earlier of: (i) the date on which Credit Rating of Purchaser’s Guarantor is at least BBB- from S&P and Baa3 from Moody’s and Purchaser has again provided the Guarantee described in Section 14.5, or (ii)
the remainder of the Term. Should such Performance Assurance not be received by Seller by the Delivery Date or should the Performance Assurance cease to be in effect during the Term for any reason, this shall constitute an Event of Default with
respect to Purchaser pursuant to the terms of Section 18.1(b)(vii). 
  
 To secure
its obligations under this Agreement (including, but not limited to, the payment by Purchaser of any disputed amounts pursuant to Section 18.3 which are determined to be due) and to the extent Purchaser delivers Performance Assurance hereunder,
Purchaser hereby grants to Seller a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral and cash equivalent 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 Seller pursuant to this Agreement, and Purchaser agrees to take such action as Seller reasonably requires in order to perfect Seller’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 by Purchaser or a termination of the Agreement caused by Purchaser pursuant to Article 18, Seller 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
Performance Assurance, including any such rights and remedies under law then in effect; (ii) exercise its rights of setoff against any and all property of the Purchaser in the possession of Seller or its agent; (iii) draw on any outstanding Letter
of Credit issued for its benefit; and (iv) liquidate all Performance Assurance then held by or for the benefit of Seller free from any claim or right of any nature whatsoever of Purchaser, including any equity or right of purchase or redemption by
Purchaser. Seller shall apply the proceeds of the collateral realized upon the exercise of any such rights or remedies to reduce Purchaser’s obligations under the Agreement (Purchaser remaining liable for any amounts owing to Seller after such
application), subject to Seller’s obligation to return any surplus proceeds remaining after such obligations are satisfied in full. 
  

 32 

 Section 14.9 Communications. In addition to the notices and other communications provided
for elsewhere in this Agreement, Seller covenants and agrees that it will use Commercially Reasonable Efforts to promptly provide Purchaser with copies of written communications between Seller and Kendall which concern the following: (i) the failure
by Kendall to perform any of its material obligations under the Kendall PPA during the Term of this Agreement, (ii) the administration of the transactions contemplated by the Kendall PPA during the Term of this Agreement in a manner which is
materially different than the terms set forth therein, and (iii) any material dispute between Seller and Kendall in connection with the Kendall PPA which either: (A) exists on or after the Effective Date and has not already been communicated to
Purchaser as of the Effective Date or (B) occurs during or arises out of the Term of this Agreement.

 TAXES 
  
 Section 15.1 Taxes and Fees.

  
 (a) Seller shall be responsible for the payment of, and the
Reservation Payments, Energy Payments, Guaranteed Heat Rate Payments and other amounts payable by Purchaser to Seller hereunder shall not be subject to adjustment for, Taxes (other than Change-in-Law Taxes) imposed on Seller and its property.
Purchaser shall be responsible for the payment of, and no amount payable by Seller to Purchaser shall be subject to adjustment for, Taxes imposed on Purchaser and its property. In addition, Purchaser shall be responsible for the payment of any
Change-in-Law Taxes imposed on Seller pursuant to the Kendall PPA; provided, however, that to the extent that the Change-in-Law Taxes pertain to the Term of this Agreement Seller and Purchaser shall use Commercially Reasonable Efforts to jointly
pursue an implementation of Section 15.1(a) of the Kendall PPA (including utilizing the dispute resolution procedures of the Kendall PPA if necessary) that reflects an equitable allocation of such costs between the Parties. The Parties agree that
any adjustments made pursuant to Section 15.1(a) of the Kendall PPA in accordance with the preceding sentence shall be employed herein as a reasonable allocation of such costs between the Parties. Seller shall determine for any Billing Period the
adjustment to any payment under Section 13.1 resulting from the application of a Change-in-Law Tax for such period, and shall provide to Purchaser a certificate setting forth in reasonable detail the basis and calculation of such adjustment. In the
case of any Change-in-Law Taxes imposed on Seller for which Purchaser is responsible, Purchaser shall pay Seller the amount of such Taxes within 10 Days of Seller notifying Purchaser of the imposition of such Change-in-Law Taxes and providing
Purchaser with a certificate in reasonable detail of the amount of such Change-in-Law Taxes. If, after the imposition of Change-in-Law Taxes in respect of which Purchaser has made a payment to Seller under this Section 15.1(a), a subsequent
Change-in-Law results in a reduction of such Change-in-Law Taxes, then the obligation of Purchaser to pay for Change-in-Law Taxes shall be reduced to such extent, and if such Change-in-Law affects Change-in-Law Taxes as to which Purchaser has
already made such payments under this Section 15.1(a), Seller shall reimburse Purchaser an amount equal to such reduction in Taxes. 
  
 (b) Seller shall provide Purchaser with written notice, as soon as reasonably practicable, but in no event less than 10 Days prior to the date on which
Change-in-Law Taxes imposed on Seller would become applicable, of such Change-in-Law Taxes. Purchaser shall have the right to Contest, in the name of either or both Parties, as required, and Seller shall Contest in the name of Kendall if requested
by Purchaser the imposition of any Change-in-Law Taxes, and Purchaser shall make any payments to Seller in respect of such Change-in-Law Taxes when required under this Agreement, but subject to refund in the event that Purchaser or Seller, as
applicable, prevails in such Contest; provided that Purchaser shall notify Seller in writing of its decision to Contest; and provided, further, that Purchaser shall be responsible for any costs and expenses (including the costs
and expenses of Seller) relating to such Contest. 
  
 (c) Each
Party shall provide the other Party upon written request a certificate of exemption or other reasonably satisfactory evidence of exemption if any exemption from or reduction of any Tax is applicable. Each Party shall exercise Commercially Reasonable
Efforts to obtain and to cooperate in obtaining any exemption from or reduction of any Tax. Each Party shall notify the other Party of any proposal to implement a Change-in-Law Tax. 
  

 33 

 Section 15.2. Change-in-Law. If the capital or variable costs of the financing, operation or
maintenance of the Dedicated Units change as a result of a Change-in-Law, the Reservation Payment, the Energy Payment, the Guaranteed Heat Rate Payment shall be adjusted, as appropriate, to correspond to the amount that such Payments, costs and/or
amount were adjusted under Section 15.2 of the Kendall PPA as of the date that such changed costs were implemented under the Kendall PPA; provided, however that to the extent that the Change-in-Law pertains to the Term of this Agreement Seller and
Purchaser shall use Commercially Reasonable Efforts to jointly pursue an implementation of Section 15.2 of the Kendall PPA (including utilizing the dispute resolution procedures of the Kendall PPA if necessary) that reflects an equitable allocation
of such costs between the Parties. The Parties agree that any adjustments made pursuant to Section 15.2 of the Kendall PPA in accordance with the preceding sentence shall be employed herein as a reasonable allocation of such costs between the
Parties. Seller shall not be entitled to a Change in Law cost increase to the extent caused by Seller’s failure to comply with Section 5.4(b). Seller shall submit to Purchaser a certificate setting forth in reasonable detail the basis of and
the calculation for, such adjustments. Within 10 Days after its receipt of such certificate, Purchaser shall notify Seller whether it approves or disapproves of Seller’s adjustments, If Purchaser approves of such adjustments within such 10 Day
period or the adjustments shall be determined to be due Seller by dispute resolution, the adjustments shall become effective under this Agreement. 
  
 ARTICLE XVI 
  
 INSURANCE 
  
 Section 16.1 Insurance Required. Seller shall use Commercially Reasonable Efforts in accordance with its rights as purchaser under the Kendall PPA to cause Kendall to carry and maintain or cause to be carried and maintained no less
than the insurance coverages listed in Appendix D of the Kendall PPA, applicable to all operations undertaken by Kendall and Kendall’s personnel in the minimum amounts (limits) indicated in Appendix D of the Kendall PPA. Except as provided in
Appendix D of the Kendall PPA, Seller shall use Commercially Reasonable Efforts to cause Kendall to place in effect the required insurance coverages as of the Delivery Start Date and to maintain the same in effect throughout the Term of this
Agreement. To the extent that Seller receives any proceeds of insurance maintained by Kendall, such proceeds shall be allocated pro rata between Purchaser and Seller based upon the then-remaining Term of this Agreement (and any subsequent remainder
of the Assignment Period (as defined in the Assignment and Assumption Agreement)) and the term of the Kendall PPA remaining after the expiration of the Term of this Agreement (and any subsequent remainder of the Assignment Period). 
  
 Section 16.2 Evidence and Scope of Insurance.

with two original copies of insurance certificates reasonably acceptable to Purchaser evidencing the effectiveness of the insurance coverages required to be maintained. A complete copy of each policy shall be provided to Purchaser upon request.

  
 (b) Seller shall use Commercially Reasonable Efforts in
accordance with its rights as purchaser under the Kendall PPA to cause Kendall to maintain insurance policies in conformity with Section 16.2(b) of the Kendall PPA.

request that Purchaser be named as an additional insured (except in the case of worker’s compensation insurance) under the insurance policies to be maintained by Kendall pursuant to the Kendall PPA. To the extent that Kendall will incur a cost
or expense in order to name Purchaser as such an additional insured, Purchaser shall either pay such cost or expense or Purchaser shall not be named as such an additional insured. 
  
 (ii) This section is intentionally deleted.

rights as purchaser under the Kendall PPA to cause Kendall to maintain insurance policies in conformity with Section 16.2(d) of the Kendall PPA.

 Section 16.3 Claims Made Insurance; Modification of Insurance.

cause Kendall to maintain insurance policies in conformity with Section 16.3(a) of the Kendall PPA. 
  
 (b) If any insurance coverages required by the Kendall PPA are unavailable on reasonable commercial terms, Seller shall (i) use Commercially Reasonable
Efforts in accordance with its rights as purchaser under the Kendall PPA to obtain from Kendall (upon receipt of which Seller shall promptly provide to Purchaser) detailed information as to the maximum amount of available coverage that it is able to
purchase and (ii) be required to obtain Purchaser’s consent which shall then be communicated to Kendall as to the adequacy of said coverage under the circumstances prevailing at the time, which consent Purchaser shall not unreasonably withhold
or delay. 
  
 ARTICLE XVII 
  
 FORCE MAJEURE EVENT

mean causes or events that are beyond the reasonable control of, without the fault or negligence of, the Party claiming such Force Majeure Event, and preventing or delaying the performance of the Party claiming excuse under this Agreement including,
without limitation, acts of God; unusually severe actions of the elements such as floods, hurricanes, or tornadoes; sabotage; terrorism; war; riots or public disorders; Emergency Conditions; with respect to Seller, any Force Majeure Event of Kendall
under the Kendall PPA; or any actions or failures to act of any Governmental Agency (including expropriation, requisition, Change-in-Law). 
  
 (b) Force Majeure Event shall not include: (i) the failure of performance of third-party suppliers of goods or services, including, without limitation, a
defect in the manufacture, design or installation of the Facility which could reasonably have been avoided by compliance with Prudent Industry Practices (ii) any failure of, or delay in performance, or any full or partial curtailment in the electric
output of the Facility that is caused by, or arises from any labor dispute or strike by Kendall’s employees (except to the extent arising out of a strike or labor action by employees or labor organizational members not employed at the Facility,
including without limitation, a national strike, any of which shall be a Force Majeure Event), (iii) the unavailability of equipment which could reasonably have been avoided by compliance with Prudent Industry Practices, (iv) changes in market
conditions that affect the price of fuel, energy, or capacity, (v) the failure timely to apply for or to obtain Governmental Approvals for the construction or operation of the Facility, or (vi) any Delivery Excuse; except to the extent that item is
caused by an event that that would be a Force Majeure Event with respect to the non-performing Party as described above. 
  

 35 

 Section 17.2 Applicability of Force Majeure Event. Neither Party shall be in breach or liable for
any delay or failure in its performance under this Agreement to the extent such performance is prevented or delayed due to a Force Majeure Event, provided that: 
  
 (a) the non-performing Party shall give the other Party written notice within 48 hours of the commencement of the Force
Majeure Event, with details to be supplied within 10 Days after the commencement of the Force Majeure Event further describing the particulars of the occurrence of the Force Majeure Event after such commencement the non-performing party shall be
excused for breach or liability for any delay or failure in its performance hereunder; 
  
 (b) the delay in performance shall be of no greater scope and of no longer duration than is directly caused by the Force Majeure Event; 
  
 (c) the Party whose performance is delayed or prevented shall proceed with Commercially Reasonable Efforts to overcome the
events or circumstances preventing or delaying performance and shall provide weekly written progress reports to the other Party during the period that performance is delayed or prevented describing actions taken and to be taken to remedy the
consequences of the Force Majeure Event, the schedule for such actions and the expected date by which performance shall no longer be affected by the Force Majeure Event; and 
  
 (d) when the performance of the Party claiming the Force Majeure Event is no longer being delayed or prevented, that Party
shall give the other Party written notice to that effect: and 
  
 (e) except as specifically provided in this Article XVII, a Force Majeure Event shall not excuse any obligation to make any payments that are otherwise due and payable pursuant to this Agreement. 
  
 Section 17.3 Other Effects of Force Majeure Events. 
  
 (a) If any Force Majeure Event claimed by a Party shall continue for more
than twelve Months from the date of notice provided by such Party in Section 17.2(a), the Parties shall attempt to mutually agree as to whether such termination right should be exercised. If the Parties are unable to agree within thirty (30) Days
after such right of termination arose, Seller shall have the exclusive right to elect whether to terminate this Agreement which shall be evidenced by written notice to Purchaser specifying such as well as the date of termination. Other than the
payment of any costs and liabilities incurred prior to the effective date of such termination, both Parties agree that neither Party shall have any liability to the other as a result of the termination of this Agreement pursuant to this Section
17.3.  
  
 (b) To the extent that Seller is unable to
deliver all or part of the Actual Contract Capacity of a Dedicated Unit as a result of a Force Majeure Event claimed by Seller in accordance with Section 17.2, as to that Dedicated Unit to the extent that the Actual Contract Capacity is not
available as a result of such Force Majeure Event; Purchaser’s payments of the Reservation Payment (the “Force Majeure Fixed Payments”) shall be reduced for the period of Force Majeure in accordance with the following formula:

  
 FMFP = RP * APC / PC 
  
 where 
  
 FMFP means the Force Majeure Fixed Payments due for the Billing Period to which the Force Majeure Event excuse applies.

  

 36 

 RP means the Reservation Payment which would be due Seller for the period under Sections 10.1, but for
the application of this Section 17.3. 
  
 APC means the sum of
(i) the amount of Contract Capacity actually available multiplied by the number of hours in the period, and (ii) the amount of any Contract Capacity rendered unavailable by reason of Scheduled Outage or Delivery Excuse, except to the extent that the
Delivery Excuse is treated as a Force Majeure Event claimed by Seller under Section 17.1, times the number of hours in the period to which such unavailability is applicable. 
  
 PC means the total amount of Contract Capacity multiplied by the number of hours for the period. 
  
 The foregoing shall not affect the obligation of Purchaser to pay Seller the Reservation
Payment for Replacement Power or any other payment obligation of Purchaser. Subject to the foregoing, if Purchaser shall be unable to accept the Actual Contract Capacity or Net Electrical Output as a result of a Force Majeure Event claimed by
Purchaser, Purchaser shall remain obligated to pay the Reservation Payment to Seller pursuant to Section 10.1 and any other payments due under the Agreement for the period of such Force Majeure Event. 
  
 Section 17.4 Delivery Excuse. 
  
 (a) As used in this Agreement, “Delivery Excuse” shall
mean: (i) any breach by Purchaser of its obligations under this Agreement; (ii) any delay or failure by Purchaser in giving any approval within the times required under this Agreement; (iii) any delay or failure by Purchaser in performing any
obligation under this Agreement; (iv) any delay or failure of Purchaser to deliver Fuel or to accept Actual Contract Capacity or Net Electrical Output as required under this Agreement unless such failure is the result of Seller’s unexcused
failure to perform under this Agreement or Kendall’s unexcused failure to perform under the Kendall PPA, (v) any failure of Purchaser to maintain adequate transmission rights to take delivery of the Net Electric Output of a Dedicated Unit or
Replacement Power in accordance with the Agreement; (vi) delivery of Non-Conforming Fuel in accordance with Section 8.5(b); (vii) any curtailment or disconnection of the Dedicated Units from the Electrical Transmission System by the Control Center,
or any other entity with jurisdiction over the Electrical Transmission System, to the extent such curtailment or disconnection is not caused by fault of the Seller or Kendall, and provided Seller or Kendall, as applicable, Contests such action in
the event Seller or Kendall, as applicable, has an opportunity to Contest and concludes in its judgment, reasonably exercised, that a Contest is warranted; or (viii) any Emergency Condition to the extent not caused by the fault of Seller, the fault
of Kendall or an Event of Force Majeure. 
  
 (b) Seller shall not
be liable for or deemed in breach of this Agreement to the extent the performance of its obligations under this Agreement is delayed or prevented by a condition of Delivery Excuse; provided that if Seller determines that its performance is or has
been affected by a condition of Delivery Excuse: 
  
 (i)
Promptly after receiving notice from Kendall, Seller shall give Purchaser written notice of such condition, with details to be supplied further describing the particulars of the occurrence promptly after Seller receives such information from
Kendall; 
  
 (ii) Any delay in performance shall be of no greater
scope and of no longer duration than is directly caused by the Delivery Excuse; and 
  
 (iii) Promptly after receiving notice from Kendall, Seller shall promptly notify Purchaser when the condition of Delivery Excuse is no longer delaying or preventing Seller’s performance. 
  
 (c) To the extent that Seller is prevented or delayed in delivering Actual
Contract Capacity or Net Electrical Output from such Dedicated Unit as a result of a Delivery Excuse in accordance with Section 17.4(b), then Seller shall have no obligation to provide Replacement Power to Purchaser with respect to such failure of
delivery, and, except as provided in Section 17.3(b) above, Purchaser shall remain obligated to pay the Reservation Payment pursuant to Section 10.1 during the period of such Delivery Excuse.

 (v) Any representation made by Seller under Article XIV shall be false in any material respect when made, unless cured within thirty (30) Days after notice by Purchaser; and 
  
 (vi) Seller shall fail to comply with any other material provision of this
Agreement (other than the obligation to pay money when due) and (i) such failure shall continue uncured for 30 Days after notice thereof by Purchaser, and (ii) such failure is not capable of being cured within such period of 30 Days with the
exercise of reasonable diligence, then such cure period shall be extended for an additional reasonable period of time (not to exceed 120 Days) so long as Seller is exercising reasonable diligence to cure such failure; 
  
 (b) The occurrence of any one of the following shall constitute an Event of
Default with respect to Purchaser: 
  
 (i) Purchaser shall fail
to make payments for undisputed amounts due under this Agreement to Seller within thirty (30) Days after notice from Seller that such payment is due; 
  
 (ii) Purchaser shall: (a) admit in writing its inability to pay its debts as such debts become due; (b) make a general assignment or an arrangement or
composition with or for the benefit of its creditors; (c) fail to controvert in a timely and appropriate manner, or acquiesce in writing to, any petition filed against such Party under any bankruptcy or similar law; (d) take any action for the

money when due), and such failure shall continue uncured for 30 Days after notice thereof by Seller, provided that if such failure is not capable of being cured within such period of 30 Days with the exercise of reasonable diligence, then
such cure period shall be extended for an additional reasonable period of time (not to exceed 120 Days) so long as Purchaser is exercising reasonable diligence to cure such failure; and 
  
 (vii) The failure of Purchaser to satisfy the credit requirements set forth in Section 14.8 hereof, if such failure is not
remedied within three (3) Business Days after written notice from Seller; 
  
 Section 18.2 Financing Party’s Opportunity to Cure. Should an Event of Default under this Agreement occur with respect to Seller which is caused, directly or indirectly, by Kendall pursuant to the terms of
the Kendall PPA, Purchaser agrees that Purchaser will not exercise any rights arising from such Event of Default until the cure period allotted to the Financing Parties as described in Section 18.2 of the Kendall PPA has elapsed and such Event of
Default remains uncured. The Parties agree, however, that notwithstanding the prior sentence, during the continuance of any such Event of Default, Purchaser may also withhold payments due to Seller hereunder, to the extent that this Agreement would
otherwise give Purchaser that right, in which case Seller may similarly elect not to make the resulting payments due to Kendall under the Kendall PPA (a “Resulting Non Payment”). Purchaser agrees that Purchaser’s rights to
withhold such payments under the preceding sentence shall terminate on the date which is the earlier of: (a) the date on which such Event of Default is no longer continuing in effect or (b) the date on which Purchaser receives notice from Seller
that Seller has received a notice from Kendall pursuant to Section 18.1(b) of the Kendall PPA as a result of the Resulting Non Payment. Once Purchaser’s right to withhold payment expires in accordance with the previous sentence, such withheld
payment shall be due and payable to Seller within five (5) Business Days of receipt of Seller’s invoice therefor. In addition, to the extent that interest is requested of Seller by Kendall regarding any withheld payments, Purchaser agrees that
it shall pay interest on such withheld payment calculated from the original due date as provided in Section 13.5 within five (5) Business Days of receipt of Seller’s invoice therefor. 
  
 Section 18.3 Remedies for Default. Subject to the terms of Section
18.2, if an Event of Default occurs with respect to a defaulting Party at any time during the Term, the non-defaulting party may, for so long as the Event of Default is continuing, (i) establish a date consistent with Section 18.1 and Section 18.2
(which date shall be sixty (60) Days after the non-defaulting party delivers notice) (the “Early Termination Date”) on which this Agreement shall be canceled if the Event of Default has not been cured and send a written notice to
the defaulting party stating the date of such Early Termination Date with the non-defaulting party’s invoice for the Break Up Fee (as defined below), (ii) withhold any payments due in respect of this Agreement and (iii) pursue any other
remedies available at law or in equity except to the extent such remedies are limited or excluded by this Agreement. In addition to the remedies set forth in this Section 18.3, in connection with the cancellation of the Agreement on an Early
Termination Date pursuant to this Section 18.3, the defaulting Party shall pay the non-defaulting party a break-up fee of Three Million Dollars ($3,000,000) (“Break Up Fee”) within five (5) Business Days of the defaulting
party’s receipt of non-defaulting party’s invoice therefor.  
  
 Section 18.4 Seller’s One-Time Termination Right. During the period commencing on the date which is thirty (30) Days after the Effective Date and ending on the date one hundred eighty (180) Days after the
Effective Date, Seller may terminate this Agreement upon written notice of such termination to Purchaser. Seller’s termination notice shall designate an Early Termination Date between ten (10) and fifteen (15) Days after 

  

 39 

 
Purchaser’s receipt thereof. Purchaser shall calculate, in a commercially reasonable manner, a Settlement Amount for this Agreement as of the Early
Termination Date. The Gains and Losses shall be determined by Purchaser by calculating the amount that would be incurred or realized by Purchaser to replace or to provide the economic equivalent of the remaining payments and/or deliveries in respect
of the Agreement. Purchaser may determine its Gains and Losses by reference to information either available to it internally or supplied by one or more third parties including, without limitation, quotations (either firm or indicative) of relevant
rates, prices, yields, yield curves, volatilities, spreads or other relevant market data in the relevant markets. Third parties supplying such information may include, without limitation, dealers in the relevant markets, end-users of the relevant
product, information vendors and other sources of market information. Seller shall be entitled to review and evaluate a copy of all information utilized by Purchaser in calculating the Settlement Amount; provided, however, that all such information
shall be deemed to be confidential and subject to the restrictions set forth in Section 21.11, provided, further, that this information shall be utilized by Seller solely in connection with Seller’s review and evaluation of, and any dispute
regarding, the calculation of the Settlement Amount. In Purchaser’s calculation of the Settlement Amount, Purchaser shall be entitled to: (a) a termination option fee of Three Million Dollars ($3,000,000) and (b) any or all other amounts due to
Purchaser under this Agreement. All of the amounts, payments or charges referenced in the preceding sentence shall be aggregated into a single liquidated amount (the “Termination Payment”) payable by Seller. 
  
 Notice of the Termination Payment shall be given by Purchaser to Seller of
the amount of the Termination Payment. The notice shall include a written statement explaining in reasonable detail the calculation of such amount. The Termination Payment shall be made by the Party that owes it within two (2) Business Days after
such notice is effective. If Seller disputes Purchaser’s calculation of the Termination Payment, in whole or in part, Seller shall, within two (2) Business Days of receipt of Purchaser’s calculation of the Termination Payment, provide to
Purchaser a detailed written explanation of the basis for such dispute. Amounts paid as a result of any settlement or other resolution of the disputed amount shall be paid with interest thereon from the original due date as provided in Section 13.5.

  
 Section 18.5 Purchaser’s Requirement Regarding the
Assignment and Assumption Agreement. Purchaser agrees that it will use Commercially Reasonable Efforts to work diligently with Seller and/or Kendall to obtain the consent of Kendall and the Financing Parties to the assignment of the Kendall PPA
pursuant to the Assignment and Assumption Agreement. Any failure by Purchaser to comply with the provisions of this Section 18.5 shall constitute an Event of Default pursuant to the terms of Section 18.1(b)(vi);provided however that this shall not
be construed as an indication of whether any other section of this Agreement is or is not a material provision.  
  
 Section 18.6 Termination of Kendall PPA. If at any time during the Term of this Agreement the Kendall PPA is terminated for whatever reason, this
Agreement shall be deemed to have been automatically terminated at the same time as the termination of the Kendall PPA without further action by either of the Parties. Seller and Purchaser agree to reasonably settle any outstanding matters under
this Agreement with each other on a prompt basis in relation to the termination of this Agreement. Other than the payment of any costs and liabilities incurred prior to or upon the effective date of such termination, both Parties agree that neither
Party shall have any liability to the other as a result of the termination of this Agreement pursuant to this Section 18.6. The provisions of this Section shall not affect any liability of a Party as a result of the occurrence of an Event of Default
under this Agreement which liability shall be determined in accordance with Section 18.3 above. 
  
 ARTICLE XIX

the other Party and its officers, directors, Affiliates, agents, employees, contractors and subcontractors, harmless from and against any and all Claims, to the extent caused by the negligence or willful misconduct of the indemnifying Party or the
indemnifying Party’s own officers, directors, Affiliates, agents, employees, contractors or subcontractors and to the extent such Claims arise out of or relate to the indemnifying Party’s performance under this Agreement, in each case
except to the extent such Claims are caused by 

  

 40 

 
the negligence, willful misconduct, or breach of this Agreement by the indemnified Party or its officers, directors, Affiliates, agents, employees,
contractors and subcontractors. In addition, each Party shall each indemnify, defend and hold harmless the other Party from any Claims, and whether or not such Claims result from the negligence or willful misconduct of the indemnifying Party or the
indemnifying Party’s own officers, directors, Affiliates, agents, employees, contractors or subcontractors, arising from the Fuel or the Net Electrical Output that occur when risk of loss of the Fuel or Net Electrical Output is vested in the
indemnifying Party, in each case except to the extent such Claims are caused by the negligence, willful misconduct, or breach of this Agreement by the indemnified Party or its officers, directors, Affiliates, agents, employees, contractors and
subcontractors. The Parties agree that (a) the risk of loss with respect to such Claims related to Net Electric Output shall transfer from Seller to Purchaser at the Interconnection Points or the Replacement Power Delivery Points (as applicable) and
(b) the risk of loss with respect to such Claims related to Fuel shall transfer from Purchaser to Seller at the Fuel Metering Points (as more fully described in Section 8.4). The indemnifying Party shall also reimburse the indemnified Party for any

 (b) If such fines, penalties or other costs are assessed against Purchaser
by any Governmental Agency or court of competent jurisdiction due to the non-compliance by Kendall with any Laws or Governmental Approvals, Seller shall use Commercially Reasonable Efforts in accordance with its rights as purchaser under the Kendall
PPA to recover from Kendall (a) any and all losses, liabilities, damages and claims suffered or incurred because of the failure of Kendall to comply therewith, and (b) any and all legal or other expenses (including attorneys’ fees) reasonably
incurred by Purchaser in connection with such losses, liabilities, damages and claims. Seller shall promptly remit to Purchaser whatever it receives in connection therewith from Kendall. 
  
 (c) If such fines, penalties or other costs are assessed against Seller by any Governmental Agency or court of competent
jurisdiction due to the non-compliance by Purchaser with any Laws or Governmental Approvals, Purchaser shall indemnify and hold harmless Seller against any and all losses, liabilities, damages and claims suffered or incurred because of the failure
of Purchaser to comply therewith. Purchaser shall also reimburse Seller for any and all legal or other expenses (including attorneys’ fees) reasonably incurred by Seller in connection with such losses, liabilities, damages and claims.

  
 Section 19.3 Limitations of Liability, Remedies and
Damages. 
  
 (a) Each Party acknowledges and agrees that in
no event shall any partner, shareholder, owner, officer, director, employee, or Affiliate of either Party be personally liable to the other Party for any payments, obligations, or performance due under this Agreement or any breach or failure of
performance of either Party and the sole recourse for payment or performance of the obligations under this Agreement shall be against Seller or Purchaser and each of their respective assets and not against any other Person, except for such liability
as expressly assumed by an assignee pursuant to an assignment of this Agreement in accordance with the terms hereof. 
  
 (b) This section has been intentionally deleted. 
  
 (c) Notwithstanding any provision of this Agreement to the contrary, after the Delivery Start Date of a Dedicated Unit, Seller shall have no obligation
to deliver Replacement Power with respect to such Dedicated Unit to Purchaser, and Seller shall not be liable for any claims, damages or liabilities of any kind resulting from a Forced Outage or other failure to deliver Actual Contract Capacity or
Net Electrical Output from such Dedicated Unit to Purchaser or for such Dedicated Unit to operate within the Design Limits (other than (i) as reflected in the calculation of Availability Adjustment Factor, (ii) Seller’s obligation to reimburse
Purchaser for 

  

 41 

 
Replacement Power requested by Seller to be provided pursuant to Sections 6.3, and Appendix E or, (iii) pursuant to Section 19.1, in which event this
limitation of liability shall not apply); provided that the foregoing shall not limit the liability of Seller upon cancellation of this Agreement upon an Event of Default of Seller. 
  
 (d) THE PAYMENT, EXPRESS REMEDY OR MEASURE OF DAMAGES SET FORTH IN SECTIONS,
6.3, 8.3, 9.4, 10.1(b), 10.4, 12.1, 13.4, 13.5, 17.3, 18.3, 19.1, 19.2, AND THIS SECTION 19.3 SHALL BE THE SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO SUCH SECTIONS. EACH PARTY’S LIABILITY SHALL BE LIMITED AS SET FORTH IN SUCH PROVISION AND ALL
OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY PROVIDED IN THIS AGREEMENT, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES SUFFERED BY THAT PARTY OR BY ANY
CUSTOMER OR ANY PURCHASER OF THAT PARTY, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE; PROVIDED THAT THE FOREGOING SHALL NOT LIMIT DAMAGES FOR BREACH BY
SELLER BASED ON THE INCREASE, IF ANY, IN PURCHASER’S COST OF OBTAINING REPLACEMENT POWER FROM ANOTHER SOURCE (WHETHER OR NOT SUCH REPLACEMENT POWER IS ACTUALLY PURCHASED BY PURCHASER) OVER THE AMOUNT WHICH WOULD BE PAYABLE BY PURCHASER UNDER
THIS AGREEMENT WITH RESPECT TO SUCH POWER NOR LIMIT DAMAGES FOR BREACH BY PURCHASER BASED ON THE REDUCTION, IF ANY, IN PAYMENTS TO SELLER FROM THE SALE OF POWER FROM THE DEDICATED UNITS ARISING OUT OF SUCH BREACH. 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, WITHOUT LIMITATION, THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR
ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE LIQUIDATED
DAMAGES CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS. NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, PURCHASER SHALL NOT BE LIABLE FOR ANY COSTS, CLAIMS OR DAMAGES WHICH ARE CALCULATED WITH RESPECT TO THE PERIOD OF
TIME BEFORE OR AFTER THE TERM; UNDER NO CIRCUMSTANCES SHALL PURCHASER BE LIABLE FOR ANY COSTS, CLAIMS OR DAMAGES WHICH OCCUR DURING OR ARISE OUT OF A PERIOD OF TIME EITHER BEFORE OR AFTER THE TERM. 
  
 (e) The provisions of this Article XIX shall survive the termination of this
Agreement.

a dispute under this Agreement, such dispute shall be referred by each Party’s representatives, respectively, to a senior officer designated by Seller and a senior officer designated by Purchaser for resolution upon five Days’ written
notice from either Party. 
  
 (c) The Parties hereto agree (i) to
attempt to resolve all disputes arising hereunder promptly, equitably and in a good faith manner; and (ii) to provide each other with reasonable access during normal business hours to any and all non-privileged records, information and data
pertaining to any such dispute. 
  

 42 

 Section 20.2 Arbitration. 
  
 (a) In the event that any dispute between the Parties is unable to be resolved pursuant to Section 20.1 within 30 Days of
the written notice described in Section 20.1(b), then either Party may commence a proceeding with respect to such dispute by written notice of arbitration specifying the matter to be arbitrated. 
  
 (b) Within twenty (20) Days of the notice given in Section 20.2 (a), the
Parties shall select three (3) AAA approved commercial arbitrators, unless the Parties otherwise agree in writing to select the arbitrators from another source. To select these arbitrators, the Parties shall alternately strike names from a list of
commercial arbitrators knowledgeable or experienced in the industry with no financial interest in any Party or any Affiliate of any Party obtained from the AAA or other agreed upon source, with the Party furnishing the Notice of Arbitration striking
first, until three (3) Persons’ names remain on such list. Such Persons shall become the arbitrators of the matter. In the event any Person selected to be an arbitrator is unable or unwilling to serve, the process shall be repeated until three
(3) arbitrators have been selected and have agreed to hear and resolve the dispute. 
  
 (c) The arbitrators shall permit each Party to conduct reasonable discovery as promptly and expeditiously as possible (and both Parties shall cooperate to this end). Discovery shall be limited to requests for the
production of documents and examination upon deposition of witnesses designated as hearing witnesses. Each Party’s requests for, and responses to discovery including examination upon deposition shall be completed within sixty (60) Days of the
arbitrators’ selection. The Parties may modify the period for discovery by mutual agreement. The arbitrators shall resolve any discovery disputes between the Parties that, after using their best efforts, the Parties cannot resolve themselves.

  
 (d) The hearing shall be initiated as promptly and
expeditiously as possible (and the Parties shall cooperate to this end) and, in no event more than thirty (30) Days after the conclusion of the discovery period. The rules of evidence of AAA shall apply to the presentation of evidence. Each Party
shall file written direct testimony with the arbitrators and serve a copy on the other Party. Each Party shall be permitted to make opening statements with the Party demanding arbitration presenting its opening statement first. Immediately after
opening statements, the Party demanding arbitration shall then present evidence in support of its position. The other Party then shall present evidence in support of its position. All witnesses must testify under oath, and a stenographic record and
transcript of the hearing shall be made. Each Party shall have an opportunity to cross-examine the other Party’s witnesses. The Parties shall be permitted to make closing statements. The Party demanding arbitration shall present its statement
first. The arbitrators shall conclude the hearing within thirty (30) calendar Days of its commencement. The period for concluding the hearing may be modified by mutual agreement of the Parties. 
  
 (e) The Parties shall submit proposed orders following the completion of the
hearing unless otherwise agreed by the Parties and approved by the arbitrators. Pre-hearing briefs may be submitted and shall be served on other Parties. The pre-hearing briefs must be received by the arbitrators and the other Party no later than
seven Business Days prior to commencement of the hearing. The briefing schedule provided herein may be modified by mutual agreement of the Parties with the approval of the arbitrators. 
  
 (f) The determination and/or award of the arbitrators, whichever is appropriate, shall be made no later than thirty (30)
Days from the date of the completion of the hearing. Such determination and/or award shall be conclusive, final, and binding, subject only to the outcome of confirmation or vacation proceedings, if any, under applicable Law. To the extent that an
award includes an amount of money, such award shall include interest at the Contract Interest Rate, and such interest shall accrue from the dates on which such money should have been paid to the prevailing Party or was incorrectly paid by that
Party. 
  
 (g) Unless the Parties otherwise agree in writing,
arbitration under this Agreement shall be conducted in Chicago, Illinois. 
  
 (h) Arbitration under this Agreement shall be governed by the AAA Commercial Arbitration Rules (or any successor thereto) in effect at the time of arbitration, unless the Parties mutually agree to another set of rules
or body of Law, provided that if any specific provision of this Section conflicts with the then effective AAA Commercial Arbitration Rules, or other set of rules or body of Law mutually agreed to by the parties, then the provisions of this Section
shall govern. 
  

 43 

 (i) The costs of the arbitration proceedings, other than the Parties’ own expenses, shall be shared
equally by the Parties. 
  
 (j) The arbitrators shall have no
power to amend or add to this Agreement, but shall have the authority to interpret the language of such Agreements and make findings of fact, order specific performance and provide injunctive relief as if the arbitrators were a court. Subject to
such limitation, the decision of the arbitrators shall be final and binding. Judgment on an award may be enforced in any court of competent jurisdiction. Upon request of either Party, the arbitrators may issue such orders for interim relief as may
be deemed necessary to safeguard the property that is the subject of arbitration or otherwise avoid irreparable harm to a Party, without prejudice to the rights of the Parties to the final determination of the dispute. Either Party may, without
inconsistency with this Agreement, seek from any court of competent jurisdiction any interim or provisional relief that may be necessary to protect the rights or property of that Party, pending the establishment of the arbitration tribunal.

be subject to the terms of the Master Netting, Setoff, Security and Collateral Agreement, dated August 6, 2004, between the Parties. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors
and assigns. 
  
 Section 21.7 Waiver. Any term or
condition of this Agreement may be waived at any time by the Party hereto that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such
term or condition. The failure or delay of either Party to require performance by the other Party of any provision of this Agreement shall not affect its right to require performance of such provision unless and until such performance has been
waived by such Party in writing in accordance with the terms hereof. No waiver by either Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or

Agreement may be executed in counterparts, all of which shall constitute one agreement binding on both Parties hereto and shall have the same force and effect as an original instrument, notwithstanding that both Parties may not be signatories to the
same original or the same counterpart. 
  
 Section 21.11
Confidential Information. 
  
 (a) Prior to the dissemination of the
initial public disclosure of this Agreement and the transactions contemplated therein, the Parties shall mutually agree upon the text of such disclosure. 
  
 (b) The terms contained in this Agreement are confidential information, and from and after the initial disclosure contemplated by paragraph (a) above, the Parties shall
not disclose any such additional confidential information to any third party (other than the Party’s Affiliates or its lenders, counselors, accountants or rating agencies who have agreed to keep such terms confidential) without first obtaining
the prior written consent of the non-disclosing Party. Notwithstanding the foregoing sentence, nothing herein shall prohibit either Party from making any public disclosure which it, with advice of counsel, deems reasonably necessary to comply with
applicable Laws, including but not limited to securities laws or rules or regulations of a stock exchange or market on which the securities of the disclosing Party or any of its Affiliates are listed; provided that the disclosing Party provide the
non-disclosing Party as much advance notice of such public disclosure as is practicable under the circumstances. Once the terms contained in this Agreement become generally available to the public as a result of the Parties’ actions in
conformity with the provisions of this Sections 21.11 (a) and (b), the prohibitions on disclosure contemplated by this Section 21.11(b) shall have no further force and effect. 
  
 (c) Any information provided by either Party to the other Party pursuant to this Agreement and labeled “CONFIDENTIAL” shall be
utilized by the receiving Party solely in connection with the purposes of this Agreement and shall not be disclosed by the receiving Party to any third party (other than the Party’s Affiliates or its lenders, counselors, accountants or rating
agencies who have agreed to keep such terms confidential), except with the providing Party’s consent, and upon request of the providing Party shall be returned thereto. Notwithstanding the 

  

 46 

 
above, the Parties acknowledge and agree that such information may be disclosed (i) if the disclosure would be permitted by the second sentence of Section
21.11(b) above, or (ii) to actual and prospective suppliers and potential suppliers of major equipment to the Facility and other third parties as may be necessary for Purchaser and Seller to perform their obligations under this Agreement. To the
extent that such disclosures pursuant to clause (ii) of the preceding sentence are necessary, the Parties also agree that they shall endeavor in disclosing such information to seek to preserve the confidentiality of such disclosures. This provision
shall not prevent either Party from providing any confidential information received from the other Party to any court in accordance with a proper discovery request or in response to the reasonable request of any Governmental Agency charged with
regulating the disclosing Party’s affairs, provided that, if feasible, the disclosing Party shall give prior notice to the other Party of such disclosure and, if so requested by such other Party, shall have used all reasonable efforts to
oppose or resist the requested disclosure, as appropriate under the circumstances, or to otherwise make such disclosure pursuant to a protective order or other similar arrangement for confidentiality. 
  
 (d) In addition to any other rights afforded by law or under this Agreement, the
non-disclosing Party shall be entitled to injunctive relief in order to protect its rights under this Section 21.11. 
  
 Section 21.12 Independent Contractors. The Parties are independent contractors. Nothing contained herein shall be deemed to create an association,
joint venture, partnership or principal/agent relationship between the Parties hereto or to impose any partnership obligation or liability on either Party. Neither Party shall have any right, power or authority to enter into any agreement or
commitment, act on behalf of, or otherwise bind the other Party in any way. 
  
 Section 21.13 Third Parties. This Agreement is intended solely for the benefit of the Parties. Nothing in this Agreement shall be construed to create any duty or liability to, or standard of care with reference
to, any other Person.

headings contained in this Agreement are solely for the convenience of the Parties and should not be used or relied upon in any manner in the construction or interpretation of this Agreement.
