Indenture 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

(including any Exchange Notes issued in exchange therefor) and the Series B Second Lien Notes (including any Exchange Notes issued in exchange therefor) (collectively referred to herein as the “Notes”) are separate series of Notes,
but shall be treated as a single class of securities under the Indenture, unless otherwise specified in the Indenture. In addition, the Notes will be treated along with certain other Pari Passu Secured Indebtedness of the Issuer as a single class
for amendments and waivers and for taking certain other actions. The terms of the Series B Second Lien Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the
“Trust Indenture Act”). The Series B Second Lien Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Series B Second Lien
Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, TCEH and/or any of its Restricted Subsidiaries may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other
covenants contained in the Indenture. If the aggregate principal amount of First Lien Obligations, Notes and Pari Passu Secured Indebtedness surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, then all First Lien
Obligations properly tendered for purchase shall be purchased, and, any remaining Collateral Excess Proceeds shall be applied to purchase the Notes and any other Pari Passu Secured Indebtedness properly tendered for purchased on a pro rata basis,
based on the accreted value or principal amount of the Notes or such other Pari Passu Secured Indebtedness tendered. 
 (e) TCEH
may, at its option, make a Collateral Asset Sale Offer using proceeds from any Asset Sale of Collateral at any time after consummation of such Asset Sale; provided that such Collateral Asset Sale Offer shall be in an aggregate amount of not
less than $25.0 million. Upon consummation of such Collateral Asset Sale Offer, any Net Proceeds not required to be used to purchase First Lien Obligations, Notes and Pari Passu Secured Indebtedness shall not be deemed Collateral Excess Proceeds.

DEFAULTS AND REMEDIES. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or
the Required Holders of at least 30% in aggregate principal amount of the Required Debt may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes of the affected series to be due and
payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders
may not enforce the Indenture, the Notes or the Guarantees except as provided in the Indenture. Subject to certain limitations, Required Holders of a majority in aggregate principal amount of the Required Debt may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, Additional Interest, if any, or interest) if it determines that
withholding notice is in their interest. The 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 required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuer is required within five Business Days after becoming aware of any Default, to deliver to the
Trustee a statement specifying such Default and what action the Issuer proposes to take with respect thereto.

the Registration Rights Agreement). 
 (16) GOVERNING LAW. THE INDENTURE, THE SERIES B SECOND LIEN NOTES AND THE
GUARANTEES THEREOF SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Lien Notes and the Trustee may use CUSIP/ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Series B Second Lien Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

	Re:	  	[15% Senior Secured Second Lien Notes due 2021, Series B] (the “Notes”)

 Ladies and Gentlemen: 
 In connection with our proposed sale of
$             aggregate principal amount of Notes, we confirm that: 
 1. We understand that any subsequent transfer of the Notes is subject to certain restrictions and conditions set forth in the Indenture dated as of October 6, 2010 (as amended, supplemented or
otherwise modified from time to time) relating to the Notes (the “Indenture”) and the undersigned agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes except in compliance with, such restrictions and
conditions and the Securities Act of 1933, as amended (the “Securities Act”). Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Indenture. 

2. We understand that the Notes have not been registered under the Securities Act or any other applicable securities law, and that the
Notes may not be offered, sold or otherwise transferred except as permitted in the following sentence. We agree, on our own behalf and on behalf of any accounts for which we are acting as hereinafter stated, that if we should offer, sell, transfer,
pledge, hypothecate or otherwise dispose of any Notes within one year after the original issuance of the Notes, we will do so only (A) to the Issuer or any subsidiary thereof, (B) inside the United States to a “qualified institutional
buyer” in compliance with Rule 144A under the Securities Act, (C) outside the United States in an offshore transaction in compliance with Rule 903 or 904 under the Securities Act, (D) pursuant to the exemption from registration
provided by Rule 144 under the Securities Act (if available), (E) in accordance with another exemption from the registration requirements of the Securities Act (and based upon an opinion of counsel if the Issuer so requests), (F) inside
the United States to an institutional “accredited investor” (as defined below) that, prior to such transfer, furnishes to you a signed letter substantially in the form of this letter (and an opinion of counsel if the Issuer or you so
requests), or (G) pursuant to an effective registration statement under the Securities Act, and we further agree to provide to any person purchasing any of the Notes from us a notice advising such purchaser that resales of the Notes are
restricted as stated herein and in the Indenture. 







  
 3. We understand that,
on any proposed transfer of any Notes prior to the later of the original issue date of the Notes and the last date the Notes were held by an affiliate of the Issuer pursuant to clauses 2(C), 2(D) and 2(F) above, we will be required to furnish to you
and the Issuer such certifications, legal opinions and other information as you and the Issuer may reasonably require to confirm that the proposed transfer complies with the foregoing restrictions. We further understand that the Notes purchased by
us will bear a legend to the foregoing effect. 
 4. We are an institutional “accredited investor” (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) purchasing at least $250,000 principal amount of the Notes and have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of
our investment in the Notes, and we and any accounts for which we are acting are acquiring the Notes for investment purposes and not with a view to, or offer or sale in connection with, any distribution in violation of the Securities Act, and we are
each able to bear the economic risk of our or its investment. 
 5. We are purchasing the Notes for our own account or for one
or more accounts (each of which is an institutional “accredited investor”) as to each of which we exercise sole investment discretion. 
 You, the Issuer, and counsel for the Issuer are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or
legal proceedings or official inquiry with respect to the matters covered hereby. 
  

			
	Very truly yours,
