Notes issued in definitive form shall be substantially in the form of Exhibit A-1 (in the case of the Second Lien Notes) or Exhibit A-2 (in the case of the Series B Second Lien Notes) hereto (but without, in each case, the Global Note
Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified in the “Schedule of Exchanges of Interests

ability to issue Additional Notes shall be subject, among other things, to the Issuer’s compliance with Sections 4.09 and 4.12 hereof. The Second Lien Notes and the Series B Second Lien
Notes are each a separate series of Notes but shall be treated as a single class of securities under this Indenture, except as otherwise stated herein. As a result, except as otherwise provided for in this Indenture, Holders of each series of Notes
will not have separate rights to, among other things, give notice of Defaults or to direct the Trustee to exercise remedies during an Event of Default or otherwise. Except as otherwise stated herein, the Notes offered by the Issuer and any
Additional Notes subsequently issued under this Indenture shall be treated as a single class for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references
to “Notes” for all purposes under this Indenture include any Additional Notes that are actually issued. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Indenture. Each series of Notes are a
separate series of debt, but will be treated as a single class with other series of Required Debt for certain actions and voting as set forth in this Indenture.

 At least one Officer shall execute the Notes on behalf of the Issuer by manual or facsimile signature. 
 If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

substantially in the form of Exhibit A-1 (in the case of the Second Lien Notes) or Exhibit A-2 (in the case of the Series B Second Lien Notes) hereto, as the case may be, by the manual signature of the Trustee. The signature shall
be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture.

of this First Supplemental Indenture, the Trustee shall, upon receipt of an Issuer Authentication Order, authenticate and deliver the Initial Series B Second Lien Notes. In addition, at any time, and from time to time, the Trustee shall, upon
receipt of an Issuer Authentication Order, authenticate and deliver any Additional Notes or Exchange Notes, for an aggregate principal amount specified in such Issuer Authentication Order for such Additional Notes or Exchange Notes. 

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the
Issuer.

Note and Series B Second Lien Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Issuer Authentication Order

with respect to the Series B Second Lien Notes, it shall follow the procedures specified below. 
 i. The Escrow
Proceeds Offer shall remain open for a period of not less than 20 Business Days or greater than 40 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Escrow Offer

purchase of Series B Second Lien Notes tendered in response to the Escrow Proceeds Offer. Payment for any Series B Second Lien Notes so purchased shall be made in the same manner as interest payments are made. 

ii. If the Escrow Offer Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any
accrued and unpaid interest up to but excluding the Purchase Date, shall be paid to the Person in whose name a Series B Second Lien Note is registered at the close of business on such Record Date, and no additional interest shall be payable to
Holders who tender Series B Second Lien Notes pursuant to the Escrow Proceeds Offer. 
 iii. Upon the
commencement of an Escrow Proceeds Offer, the Issuer shall send, by first-class mail, a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender
Notes pursuant to such Escrow Proceeds Offer. Any Escrow Proceeds Offer shall be made to all Holders of Series B Second Lien Notes. The notice, which shall govern the terms of the Escrow Proceeds Offer, shall state:

Proceeds Offer shall remain open; 
 (B) the Escrow Offer Amount, the purchase price and the Escrow Offer

(D) that any Series B Second Lien Note not tendered or accepted for payment shall continue to accrue interest; 


  
 11

principal amount of the Series B Second Lien Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Series B Second Lien Note purchased; 

(I) that if the aggregate principal amount of Series B Second Lien Notes surrendered by the holders thereof exceeds the
Escrow Offer Amount, the Trustee shall select the Series B Second Lien Notes to be purchased on a pro rata basis based on the principal amount of the Series B Second Lien Notes tendered (with such adjustments as may be deemed
appropriate by the Trustee so that only Series B Second Lien Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, shall be purchased); and 

(J) that Holders whose Series B Second Lien Notes were purchased only in part shall be issued new Series B Second Lien
Notes equal in principal amount to the unpurchased portion of the Series B Second Lien Notes surrendered (or transferred by book-entry transfer) representing the same indebtedness to the extent not repurchased. 

iv. On or before the Escrow Offer Purchase Date, the Issuer shall, to the extent lawful, (1) accept for payment, on a

Series B Second Lien Notes tendered and (2) deliver or cause to be delivered to the Trustee the Series B Second Lien Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Series B Second
Lien Notes or portions thereof so tendered.

be, shall promptly mail or deliver to each tendering Holder an amount equal to the purchase price of the Series B Second Lien Notes properly tendered by such Holder and accepted by the Issuer for purchase, and the Issuer shall promptly issue a new
Series B Second Lien Note, and the Trustee, upon receipt of a Issuer Authentication Order, shall authenticate and mail or deliver (or cause to be transferred by book-entry) such new Series B Second Lien Note to such Holder (it being understood that,

Counsel or Officer’s Certificate is required for the Trustee to authenticate and mail or deliver such new Series B Second Lien Note) in a principal amount equal to any unpurchased portion of
the Series B Second Lien Note surrendered representing the same indebtedness to the extent not repurchased; provided that each such new Series B Second Lien Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess
thereof. Any Series B Second Lien Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Escrow Proceeds Offer on or as soon as practicable after the

with respect to defaulted interest. Payment of interest and Additional Interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately
available funds will be required with respect to principal of and interest, premium and Additional Interest, if any, on, all Global Notes and all other Series B Second Lien Notes the Holders of which shall have provided wire transfer instructions to

Required Holders of a majority in aggregate principal amount of the Required Debt by notice to the Trustee may on behalf of the Holders of all of the Required Debt waive any existing Default or and its consequences under the Indenture except a
continuing Default in the payment of interest on, premium, if any, or the principal of any Note held by a non-consenting Holder. The Issuer and each Guarantor (to the extent that such Guarantor is so required under the Trust Indenture Act) is

 [FORM OF SUPPLEMENTAL INDENTURE 
 TO BE DELIVERED BY SUBSEQUENT GUARANTORS] 
 Supplemental Indenture (this
“Supplemental Indenture”), dated as of
                                        ,
among
                                        
(the “Guaranteeing Subsidiary”), a subsidiary of Texas Competitive Electric Holdings Company LLC, a Delaware limited liability company (“TCEH”), TCEH Finance, Inc., a Delaware Corporation (together with TCEH, the
“Issuer”), the Guarantors (as defined in the Indenture referred to below) and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). 

W I T N E S S E T H 
 WHEREAS, each of the Issuer and the Guarantors has heretofore executed and delivered to the Trustee an Indenture (the “Existing Indenture”), dated as of October 6, 2010, as
supplemented by the First Supplemental Indenture (the Existing Indenture as supplemented, the “Indenture”), dated as of October 20, 2010, providing for the issuance of an unlimited aggregate principal amount of 15% Senior
Secured Second Lien Notes due 2021 and 15% Senior Secured Second Lien Notes due 2021, Series B (together, the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary
shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Guarantee”); and 

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees as follows: 

(a) Along with all Guarantors named in the Indenture, to jointly and severally unconditionally guarantee to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 

(i) the principal of, interest, premium and Additional Interest, if any, on the Notes shall be promptly paid in full when
due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder
shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

  
 D-1









  
 (ii) in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity,
by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same
immediately. This is a guarantee of payment and not a guarantee of collection. 
 (b) The obligations hereunder
shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof
or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

(c) The following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever. 
 (d) Except as set forth in Section 5 hereto, this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental
Indenture, and the Guaranteeing Subsidiary accepts all obligations of a Guarantor under the Indenture. 
 (e) If
any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer
or the Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 

(f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 (g) As between
the Guaranteeing Subsidiary, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this
Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in
Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guaranteeing Subsidiary for the purpose of this Guarantee. 

(h) The Guaranteeing Subsidiary shall have the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the Holders under this Guarantee. 
 (i) Pursuant to
Section 10.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to
receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of 

  
 D-2









 
such other Guarantor under Article 10 of the Indenture, this new Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under
this Guarantee will not constitute a fraudulent transfer or conveyance. 
 (j) This Guarantee shall remain in
full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes
are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes and Guarantee, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as
though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned. 
 (k) In case any provision of this
Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

(l) This Guarantee shall be a general senior secured obligation of such Guaranteeing Subsidiary, ranking equally in right
of payment with all existing and future Indebtedness of the Guaranteeing Subsidiary, except to the extent such Indebtedness is expressly subordinated to the Obligations arising under a Guarantee, in which case the obligations of a Guaranteeing
Subsidiary under such Guarantee will rank senior in right of payment to such Indebtedness and will be effectively subordinated to all existing and future Indebtedness of the Guarantors that are either (1) secured by a Lien on the Collateral
that is senior or prior to the Second-Priority Liens securing a Guarantee, including first-priority Liens securing Obligations under the TCEH Senior Secured Facilities and any other First Lien Obligations (and any Permitted Liens) or
(2) secured by assets that are not part of the Collateral securing a Guarantee, in each case, to the extent of the value of the assets securing such Indebtedness. The Guarantees will be senior in right of payment to all existing and future
unsecured Indebtedness, to the extent of the value of the Collateral (after taking into consideration all first-priority Liens on the Collateral) of each Guarantor. The Notes will be structurally subordinated to Indebtedness and other liabilities of
Subsidiaries of the Issuer that do not Guarantee the Notes, if any. 
 (m) Each payment to be made by the
Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 3. EXECUTION AND DELIVERY. The Guaranteeing Subsidiary agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the
endorsement of any notation of such Guarantee on the Notes.

(b) Subject to certain limitations described in the Indenture, the Successor Person will succeed to, and be substituted

Guarantor or the Issuer, (ii) merge with an Affiliate of the Issuer solely for the purpose of reincorporating the Guaranteeing Subsidiary in the United States, any state thereof, the District of Columbia or any territory thereof or

(1)(A) any sale, exchange or transfer (by merger, wind-up, consolidation or otherwise) of the Capital Stock of the
Guaranteeing Subsidiary (including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or sale of all or substantially all the assets of the Guaranteeing Subsidiary which sale, exchange or
transfer is made in compliance with the applicable provisions of the Indenture;
