 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

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.

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

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

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.

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.
