of the Fixed Charge Coverage Ratio is made (the “Fixed Charge Coverage Ratio Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such 

  

 17 

 
incurrence, assumption, guarantee, redemption, retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or
Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (as determined in accordance with GAAP) that have been made by TCEH or any of its Restricted Subsidiaries during the four-quarter
reference period or subsequent to such reference period and on or prior to or simultaneously with the Fixed Charge Coverage Ratio Calculation Date shall be calculated on a pro forma basis assuming that all such Investments,

Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by
a responsible financial or accounting officer of TCEH to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a
revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period except as set forth in the first paragraph of this definition. Interest on
Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate or other rate shall be deemed to have been based upon the rate actually chosen, or, if none,
then based upon such optional rate chosen as TCEH may designate.

	 	Section 1.05	Acts of Holders. 

 (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person
or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Issuer. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive
in favor of the Trustee and the Issuer, if made in the manner provided in this Section 1.05. 
 (b) The fact and date of the execution
by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the

 (e) The Issuer may, in the circumstances permitted by the Trust Indenture Act, set a record date for purposes of determining the identity
of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or take any other act, or to vote or consent to any action by vote or consent authorized or permitted to be given or taken by Holders. Unless
otherwise specified, if not set by the Issuer prior to the first solicitation of a Holder made by any Person in respect of any such action, or in the case of any such vote, prior to such vote, any such record date shall be the later of 10 days prior
to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation. 
  

 42 

 (f) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any
particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any

proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and DTC that is the Holder of a Global Note may provide its
proxy or proxies to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices.

take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders. If such a record date is fixed, the
Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders
remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date. 
 (i) Within three Business Days following any vote requiring the vote of the Required Holders of Required Debt, the Issuer shall use commercially
reasonable efforts to cause the Administrative Agent (and any other representative of Required Debt, including any trustee for such Required Debt) to provide written notice to the Trustee of (i) the outstanding principal amount of Required Debt
(other than the Notes) and (ii) the results of any votes by the Required Holders of Required Debt. In addition, the Issuer shall use commercially reasonable efforts to cause the Administrative Agent (and any other representative of Required
Debt, including any trustee for such Required Debt) to provide written notice to the Trustee of any other action the Required Holders of Required Debt require the Administrative Agent (or such other representative) to undertake at their request,
including without limitation, the declaration of an Event of Default. The Trustee may rely conclusively on the information provided to it by the Administrative Agent (or such other representative), including without limitation, information provided

 (b) Global Notes. Notes issued in global form shall be substantially in the form of
Exhibit A-1 hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of
Exhibit A-1 attached 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 in the Global Note” attached thereto and each shall provide that it shall represent up to the aggregate principal amount of Notes from time to time endorsed
thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of
any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as
required by Section 2.06 hereof. 
 (c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S shall be
issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the Depositary, and registered in the name of the
Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The Restricted Period shall be
terminated upon the receipt by the Trustee of: 
 (i) a written certificate from the Depositary (if available), together with
copies of certificates from Euroclear and Clearstream (if available) certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of each Regulation S Temporary Global Note
(except to the extent of any beneficial owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who shall take delivery of a beneficial ownership
interest in a 144A Global Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b) hereof); and 
 (ii) an Officer’s Certificate from the Issuer. 
 Following the termination of the Restricted Period, beneficial interests in
each Regulation S Temporary Global Note shall be exchanged for beneficial interests in the Regulation S Permanent Global Note of the same series pursuant to the Applicable Procedures. Simultaneously with the authentication of the
corresponding Regulation S Permanent Global Note, the Trustee shall cancel the corresponding Regulation S Temporary Global Note. The aggregate principal amount of a Regulation S Temporary Global Note and the Regulation S
Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

 (d) Terms. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited.

 The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture, and the Issuer,
the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this
Indenture, the provisions of this Indenture shall govern and be controlling. 
  

 44

Section 4.10 hereof or a Change of Control Offer as provided in Section 4.14 hereof. The Notes shall not be redeemable other than as provided in Article 3 hereof. 
 Additional Notes ranking pari passu with the Initial Notes may be created and issued from time to time by the Issuer without notice to or consent
of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise as the Initial Notes; provided that the Issuer’s ability to issue Additional
Notes shall be subject, among other things, to the Issuer’s compliance with Section 4.09 hereof. The Notes offered by the Issuer and any Additional Notes subsequently issued under this Indenture will 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. The 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. As a result, Holders of the Notes will not have separate rights to, among other things, give notice of Defaults, direct the Trustee to exercise remedies during an Event of Default or otherwise or
vote for amendments and waivers. 
 (e) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating
Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to

	 	Section 2.02	Execution and Authentication. 

 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. 
 A Note shall not be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form of Exhibit A-1 attached hereto, 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. 
 On the Issue Date, the Trustee shall, upon receipt of a written order of
the Issuer signed by an Officer (an “Issuer Authentication Order”) authenticate and deliver the Initial Notes specified in such Issuer Authentication Order. 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.

 The Issuer shall
maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar

 The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or

 The Issuer initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. 
 The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent for the Notes and to act as Custodian with respect to the Global

shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional
Interest if any, or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The
Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall
serve as Paying Agent for the Notes.

or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits
under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (v) The Issuer shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under
Section 3.02 hereof and ending at the close of business on the day of selection; (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being
redeemed in part; or (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date. 
 (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note
for the purpose of receiving payment of principal of (and premium, if any) and interest (including Additional Interest, if any) on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to
the contrary. 
 (vii) Upon surrender for registration of transfer of any Note at the office or agency of the Issuer
designated pursuant to Section 4.02 hereof, the Issuer shall execute, and the Trustee shall authenticate and mail, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or
denominations of a like aggregate principal amount. 
  

 57 

 (viii) At the option of the Holder, Notes may be exchanged for other Notes of any
authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuer shall
execute, and the Trustee shall authenticate and mail, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02 hereof. 
 (ix) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06
to effect a registration of transfer or exchange may be submitted by facsimile. 
  

	 	Section 2.07	Replacement Notes. 

 If any mutilated Note is
surrendered to the Trustee, the Registrar or the Issuer and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of a Issuer
Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and
the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a Note. 
 Every replacement Note is a contractual obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder. 
  

	 	Section 2.08	Outstanding Notes. 

 The Notes outstanding at any
time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and
those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under Section 4.01 hereof, it
ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of
any thereof) holds, on a Redemption Date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 
  

	 	Section 2.09	Treasury Notes. 

 In determining whether the Holders
of the required principal amount of Notes have concurred in any direction, waiver or consent, any Notes owned by the Issuer or any Affiliate of the Issuer, shall be considered as though not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible 

  

 58 

 
Officer of the Trustee knows are so owned, shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the
pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Issuer or any obligor upon the Notes or any Affiliate of the
Issuer or of such other obligor. 
  

	 	Section 2.10	Temporary Notes. 

 Until certificates representing
Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Issuer Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have
variations that the Issuer considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for
temporary Notes. 
 Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded
to Holders, or beneficial holders, respectively, of Notes under this Indenture. 
  

	 	Section 2.11	Cancellation. 

 The Issuer at any time may deliver
Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the
Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act).
Certification of the destruction of all cancelled Notes shall be delivered to the Issuer upon the Issuer’s written request. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for
cancellation. 
  

	 	Section 2.12	Defaulted Interest. 

 If the Issuer defaults in a
payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each
case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment and at the same time the
Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12. The Trustee shall fix or cause to be fixed each such special record date and
payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. The Trustee shall promptly notify the Issuer of such special record date. At least 15 days
before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice at his or her
address as it appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid. 
 Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall
carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 
  

 59 

	 	Section 2.13	CUSIP and ISIN Numbers. 

 The Issuer in issuing the
Notes may use CUSIP and/or ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP and/or ISIN numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such
redemption shall not be affected by any defect in or omission of such numbers. The Issuer will as promptly as practicable notify the Trustee of any change in the CUSIP or ISIN numbers. 
 ARTICLE 3

	 	Section 3.01	Notices to Trustee. 

 If the Issuer elects to redeem
the Notes pursuant to Section 3.07 hereof, it shall furnish to the Trustee, at least 2 Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to Section 3.03 hereof but not more than

exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed, (b) on a pro rata basis to the extent practicable or (c) by lot or such similar method in accordance
with the procedures of the DTC. 
 In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased
shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Notes not previously called for redemption or purchase. 
 The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for
partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; no Notes of $2,000 or less can be redeemed
in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed or purchased. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

	 	Section 3.03	Notice of Redemption. 

 Subject to Section 3.09
hereof, notices of redemption shall be mailed by first-class mail, postage prepaid, at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address or otherwise in
accordance with the procedures of DTC, except that notices of redemption may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 11 hereof. Except as set forth in
Section 3.04 and Section 3.07(b) hereof, notices of redemption may not be conditional. 
 The notice shall identify the Notes to be
redeemed and shall state: 
 (a) the Redemption Date; 
 (b) the redemption price; 
 (c) if any Note is to be redeemed in part only, the portion of the principal
amount of that Note that is to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent
not redeemed will be issued in the name of the Holder of the Notes upon cancellation of the original Note; 
 (d) the name and address of the
Paying Agent; 
 (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (f) that, unless the Issuer defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the
Redemption Date; 
 (g) the paragraph or subparagraph of the Notes and/or Section of this Indenture pursuant to which the Notes called
for redemption are being redeemed; 
 (h) that no representation is made as to the correctness or accuracy of the CUSIP and/or ISIN number,
if any, listed in such notice or printed on the Notes; and 
 (i) if in connection with a redemption pursuant to Section 3.07(b) hereof,
any condition to such redemption. 
 At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name
and at its expense; provided that the Issuer shall have delivered to the Trustee, at least 2 Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this Section 3.03 (unless a
shorter notice shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 
  

	 	Section 3.04	Effect of Notice of Redemption. 

 Once notice of
redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price (except as provided for in Section 3.07(b) hereof). The notice, if
mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, 

  

 61 

 
failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the
validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption. 
  

	 	Section 3.05	Deposit of Redemption or Purchase Price. 

 Prior to
10:00 a.m. (New York City time) on the redemption or purchase date, the Issuer shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest (including Additional
Interest, if any) on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to
pay the redemption price of, and accrued and unpaid interest (including Additional Interest, if any) on, all Notes to be redeemed or purchased. 
 If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the redemption or purchase date shall be paid to the Person in whose name such Note was registered at the
close of business on such Record Date. If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid
on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in
the Notes and in Section 4.01 hereof. 
  

	 	Section 3.06	Notes Redeemed or Purchased in Part. 

 Upon
surrender of a Note that is redeemed or purchased in part, the Issuer shall issue and, upon receipt of an Issuer Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to
the unredeemed or unpurchased portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that each new Note will 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 and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new
Note. 
  

	 	Section 3.07	Optional Redemption. 

 (a) At any time prior to
November 1, 2011, the Issuer may redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional

Date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
  

 63

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 the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders and, if

withdrawing his election to have such Note purchased; 
 (viii) that, if the aggregate principal amount of Notes and Senior
Indebtedness surrendered by the holders thereof exceeds the Offer Amount, the Trustee shall select the Notes and such Senior Indebtedness to be purchased on a pro rata basis (subject to the limitations set forth in

integral multiple of $1,000 in excess thereof, shall be purchased); and 
 (ix) that Holders whose Notes were purchased only
in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer) representing the same indebtedness to the extent not repurchased. 
 (e) On or before the Purchase Date, the Issuer shall, to the extent lawful, (1) accept for payment, on a pro rata basis to the extent
necessary and subject to Section 4.10(b)(1) hereof, the Offer Amount of Notes or portions thereof validly tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered and (2) deliver or
cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof so tendered. 
  

 64

 (a) Notwithstanding
that TCEH may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and
regulations promulgated by the SEC, TCEH shall file with the SEC (and make available to the Trustee and Holders of the Notes (without exhibits), without cost to any Holder, within 15 days after it files them with the SEC) from and after the
Issue Date, 
 (1) within 90 days (or any other time period then in effect under the rules and regulations of the
Exchange Act with respect to the filing of a Form 10-K by a non-accelerated filer) after the end of each fiscal year, annual reports on Form 10-K, or any successor or comparable form, containing the information required to be contained

TCEH by furnishing financial information 

  

 66 

 
relating to such parent; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between
the information relating to such parent, on the one hand, and the information relating to TCEH and its Restricted Subsidiaries on a standalone basis, on the other hand.

Section 4.09(a) and Section 4.09(b)(12) and (14) hereof at such time.

within 30 days following such drawing or incurrence; 
 (6) Indebtedness arising from agreements of TCEH or its Restricted
Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or a Subsidiary, other than guarantees of Indebtedness

 (7) Indebtedness of TCEH to a Restricted Subsidiary; provided that any such Indebtedness owing to a Restricted
Subsidiary that is not the Issuer or a Guarantor is expressly subordinated in right of payment to the Notes; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any
Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to TCEH or another Restricted Subsidiary) shall be deemed, in each case, to be an incurrence of such Indebtedness not
permitted by this clause (7); 
 (8) Indebtedness of a Restricted Subsidiary to TCEH or another Restricted Subsidiary;
provided that if the Issuer or a Guarantor incurs such Indebtedness to a Restricted Subsidiary that is not the Issuer or a Guarantor, such Indebtedness is expressly subordinated in right of payment to the Guarantee of the Notes of such

subsequent issuance or transfer of any Capital Stock or any other event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to TCEH or
another of its Restricted Subsidiaries) shall be deemed in each case to be an issuance of such shares of Preferred Stock not permitted by this clause (9); 
 (10) Hedging Obligations; provided that (i) other than in the case of commodity Hedging Obligations, such Hedging Obligations are not entered into for speculative purposes (as determined by TCEH in its
reasonable discretion acting in good faith) and (ii) in the case of speculative commodity Hedging Obligations, such Hedging Obligations are entered into in the ordinary course of business and are consistent with past practice; 
 (11) obligations in respect of performance, bid, appeal and surety bonds and completion guarantees provided by TCEH or any of its

Preferred Stock then outstanding and incurred pursuant to this clause (12)(b), does not at any one time outstanding exceed $1,750.0 million (it being understood that any Indebtedness, Disqualified Stock or Preferred Stock incurred pursuant
to this clause (12)(b) shall cease to be deemed incurred or outstanding for purposes of this clause (12)(b) but shall be deemed incurred for the purposes of Section 4.09(a) hereof from and after the first date on which TCEH or such
Restricted Subsidiary could have incurred such Indebtedness, Disqualified Stock or Preferred Stock under the first paragraph of this covenant without reliance on this clause (12)(b)); provided, however that on a pro forma basis,
together with any amounts incurred and outstanding by Restricted Subsidiaries that are not Guarantors pursuant to Section 4.09(a) hereof and clause (14) of Section 4.09(b) hereof, no more than $1,250.0 million of Indebtedness,

this clause (13) and clause (14) of this Section 4.09(b) or any Indebtedness, Disqualified Stock or Preferred Stock of TCEH or any Restricted Subsidiary issued to so refund or refinance such Indebtedness, Disqualified Stock or
Preferred Stock of TCEH or any Restricted Subsidiary including additional Indebtedness, Disqualified Stock or Preferred Stock incurred to pay premiums (including reasonable tender premiums), defeasance costs and fees in connection therewith (the
“Refinancing Indebtedness”) prior to its respective maturity; provided, however, that such Refinancing Indebtedness: 
 (a) has a Weighted Average Life to Maturity at the time such Refinancing Indebtedness is incurred which is not less than the remaining Weighted Average Life to Maturity of the Indebtedness, Disqualified Stock or
Preferred Stock being refunded or refinanced, 
 (b) to the extent such Refinancing Indebtedness refinances
(i) Indebtedness subordinated or pari passu to the Notes or any Guarantee thereof, such Refinancing Indebtedness is subordinated or pari passu to the Notes or the Guarantee at least to the same extent as the Indebtedness being
refinanced or refunded or (ii) Disqualified Stock or Preferred Stock, such Refinancing Indebtedness must be Disqualified Stock or Preferred Stock, respectively, and 
  

 79 

 (c) shall not include Indebtedness, Disqualified Stock or Preferred Stock of a Subsidiary

(x) TCEH or a Restricted Subsidiary incurred to finance an acquisition or (y) Persons that are acquired by TCEH or any Restricted Subsidiary or merged into TCEH or a Restricted Subsidiary in accordance with the terms of this Indenture;
provided that after giving effect to such acquisition or merger, either 
 (a) TCEH would be permitted to incur at
least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first sentence of this covenant, or 
 (b) such Fixed Charge Coverage Ratio of TCEH and the Restricted Subsidiaries is greater than immediately prior to such acquisition or merger; 
 provided, however that on a pro forma basis, together with any amounts incurred and outstanding by Restricted Subsidiaries that are not
Guarantors pursuant to Section 4.09(a) hereof and clause (12) of Section 4.09(b) hereof, no more than $1,250.0 million of Indebtedness, Disqualified Stock or Preferred Stock at any one time outstanding and incurred pursuant to this
clause (14) shall be incurred by Restricted Subsidiaries that are not Guarantors; 
 (15) Indebtedness arising from the
honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within two Business Days of its

 (16) Indebtedness of TCEH or any of its Restricted Subsidiaries supported by a letter of credit issued pursuant
to any Credit Facilities, in a principal amount not in excess of the stated amount of such letter of credit; 
 (17) any
guarantee by TCEH or a Restricted Subsidiary of Indebtedness or other obligations of any Restricted Subsidiary, so long as the incurrence of such Indebtedness incurred by such Restricted Subsidiary is permitted under the terms of this Indenture, or
(b) any guarantee by a Restricted Subsidiary of Indebtedness of TCEH; provided that such guarantee is incurred in accordance with Section 4.15 hereof; 
 (18) Indebtedness of TCEH or any of its Restricted Subsidiaries consisting of (i) the financing of insurance premiums or

 (19) Indebtedness consisting of Indebtedness issued by TCEH or any of its Restricted Subsidiaries to current or former officers, directors and employees thereof, their respective estates, spouses or former spouses, in each case to finance
the purchase or redemption of Equity Interests of TCEH or any direct or indirect parent company of TCEH to the extent described in clause (4) of Section 4.07(b) hereof; and 
  

 80 

 (20) Indebtedness of TCEH or any Restricted Subsidiary to EFH Corp. or any of its
Subsidiaries consistent with past practice in an aggregate amount not to exceed $25.0 million; provided, that at the time of incurring, and after giving effect to, such Indebtedness, no Default described in Section 6.01(a)(1) and
(2) hereof shall have occurred and be continuing or would occur as a consequence thereof; provided, further, that any such Indebtedness owing to an entity that is not a Guarantor is expressly subordinated in right of payment to
the Notes. 
 (c) For purposes of determining compliance with this Section 4.09: 
 (1) in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more
than one of the categories of permitted Indebtedness, Disqualified Stock or Preferred Stock described in clauses (1) through (20) of this Section 4.09(b) or is entitled to be incurred pursuant to Section 4.09(a) hereof, TCEH, in
its sole discretion, shall classify or reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and shall only be required to include the amount and type of such Indebtedness, Disqualified Stock or
Preferred Stock in one of the above clauses; and 
 (2) at the time of incurrence, TCEH will be entitled to divide and
classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.09(a) and (b) hereof; 
 provided that
all Indebtedness outstanding under the TCEH Senior Secured Facilities on the Closing Date will be treated as incurred on the Closing Date under clause (1) of Section 4.09(b) hereof. 
 (d) Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness, Disqualified Stock or
Preferred Stock shall not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.09. 
 (e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency
shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is
incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date
of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

 The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the
Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing. 
 (f) Notwithstanding anything to the contrary, TCEH shall not, and shall not permit TCEH Finance, Inc. or any Guarantor to, directly or indirectly, incur
any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of TCEH, TCEH Finance, Inc. or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in

  

 81 

 
right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other
Indebtedness of TCEH, TCEH Finance, Inc. or such Guarantor, as the case may be. 
 For purposes of this Indenture, (1) Indebtedness that
is unsecured is not deemed to be subordinated or junior to Secured Indebtedness merely because it is unsecured, and (2) Senior Indebtedness is not deemed to be subordinated or junior to any other Senior Indebtedness merely because it has a
junior priority with respect to the same collateral. 
  

	 	Section 4.10	Asset Sales. 

 (a) TCEH shall not, and shall not
permit any of its Restricted Subsidiaries to consummate, directly or indirectly, an Asset Sale, unless: 
 (1) TCEH or such
Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by TCEH) of the assets sold or otherwise disposed of; and 
 (2) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by TCEH or such Restricted
Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; provided that the amount of: 
 (A) any
liabilities (as shown on TCEH’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of TCEH or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes or that
are owed to TCEH or an Affiliate of TCEH, that are assumed by the transferee of any such assets and for which TCEH and all of its Restricted Subsidiaries have been validly released by all applicable creditors in writing, 
 (B) any securities received by TCEH or such Restricted Subsidiary from such transferee that are converted by TCEH or such Restricted
Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Sale, and 
 (C)
any Designated Non-cash Consideration received by TCEH or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (c)
that is at that time outstanding, not to exceed 5% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received
and without giving effect to subsequent changes in value, 
 shall be deemed to be cash for purposes of this provision and for no other
purpose. 
 (b) Within 450 days after the receipt of any Net Proceeds of any Asset Sale, TCEH or such Restricted Subsidiary, at its
option, may apply the Net Proceeds from such Asset Sale, 
 (1) to permanently reduce: 
 (A) Obligations under Senior Indebtedness which is Secured Indebtedness permitted by this Indenture, and to correspondingly reduce
commitments with respect thereto; 
  

 82 

 (B) Obligations under other Senior Indebtedness (and to correspondingly reduce
commitments with respect thereto); provided that the Issuer shall equally and ratably reduce Obligations under the Notes as provided under Section 3.07 hereof, through open-market purchases (to the extent such purchases are at or above
100% of the principal amount thereof) or otherwise by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of
accrued but unpaid interest, if any; 
 (C) Obligations under the Existing Notes which have a final maturity date (as in
effect on the Closing Date) on or prior to October 15, 2016; provided that, at the time of, and after giving effect to, such repurchase, redemption or defeasance, the aggregate amount of Net Proceeds used to repurchase, redeem or defease
Existing Notes pursuant to this subclause (C) following the Closing Date shall not exceed 3.5% of Total Assets at such time; or 
 (D) Indebtedness of a Restricted Subsidiary (other than TCEH Finance, Inc.) that is not a Guarantor, other than Indebtedness owed to TCEH or another Restricted Subsidiary (or any affiliate thereof); 
 (2) to make (a) an Investment in any one or more businesses, provided that such Investment in any business is in the form of
the acquisition of Capital Stock and results in TCEH or another of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) capital
expenditures or (c) acquisitions of other assets, in each of (a), (b) and (c), used or useful in a Similar Business; or 
 (3) to make an Investment in (a) any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in TCEH or another of its Restricted Subsidiaries, as the
case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) properties or (c) acquisitions of other assets that, in each of (a), (b) and (c), replace the businesses,
properties and/or assets that are the subject of such Asset Sale; 
 provided that, in the case of clauses (2) and (3) above, a binding
commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as TCEH, or such other Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will
be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”) (and reinvest within the later of 450 days from the date of receipt of Net Proceeds and 180 days of receipt of such
commitment), and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, TCEH or such Restricted Subsidiary enters into another Acceptable Commitment (a
“Second Commitment”) within the later of (a) 180 days of such cancellation or termination or (b) the initial 450-day period; provided, further, that if any Second Commitment is later cancelled or
terminated for any reason before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds. 
 Notwithstanding
Section 4.10(b) hereof, in the event that regulatory approval is necessary for an asset or investment, or replacement, repair or restoration on any asset or investment, then TCEH or any Restricted Subsidiary shall have an additional 365 days to
apply the Net Proceeds from such Asset Sale in accordance with Section 4.10(b) hereof. 
  

 83 

 Any Net Proceeds from Asset Sales that are not invested or applied as provided and within the time period
set forth in Section 4.10(b) hereof shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes and, if
required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is
a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and
Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within 10 Business Days after
the date that Excess Proceeds exceed $200.0 million by mailing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. 
 To the extent that the aggregate amount of Notes and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, TCEH may use any remaining Excess Proceeds for general corporate
purposes, subject to other covenants contained in this Indenture. If the aggregate principal amount of Notes or the Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and
such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered. Additionally, the Issuer may, at its option, make an Asset Sale Offer using proceeds from
any Asset Sale at any time after consummation of such Asset Sale; provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of an Asset Sale Offer, any Net Proceeds not required
to be used to purchase Notes shall not be deemed Excess Proceeds and any remaining amounts may be used to make Restricted Payments to the extent permitted by clause (16) of Section 4.07(b) hereof. 
 (c) Pending the final application of any Net Proceeds pursuant to this Section 4.10, the holder of such Net Proceeds may apply such Net Proceeds
temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture. 
 (d) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection
with the repurchase of the Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 
  

	 	Section 4.11	Transactions with Affiliates. 

 (a) TCEH shall not,

transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of TCEH (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in
excess of $25.0 million, unless: 
 (1) such Affiliate Transaction is on terms that are not materially less favorable to
TCEH or its relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by TCEH or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis; and 
  

 84 

 (2) TCEH delivers to the Trustee with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate payments or consideration in excess of $50.0 million, a resolution adopted by the majority of the board of directors of TCEH approving such Affiliate Transaction and set forth in an

Restricted Subsidiary with an unrelated Person on an arm’s-length basis;

Closing Date, or any amendment thereto (so long as any such amendment is not disadvantageous to the Holders when taken as a whole as compared to the applicable agreement as in effect on the Closing Date);

stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Closing Date and any similar agreements which it may enter into thereafter; provided, however,
that the existence of, or the performance by TCEH or any of its Restricted Subsidiaries of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Closing Date shall only be
permitted by this clause (7) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous to the Holders when taken as a whole; 
  

 85 

 (8) the Transactions (including any payments made after the Closing Date in respect of

obligations under any Indebtedness or any related guarantee, on any asset or property of the Issuer or any Guarantor, or any income or profits therefrom, or
assign or convey any right to receive income therefrom, unless: 
 (1) in the case of Liens securing Subordinated
Indebtedness, the Notes and related Guarantees are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; or 
 (2) in all other cases, the Notes or the Guarantees are equally and ratably secured or are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; 
 except that the foregoing shall not apply to (a) Liens securing the Notes and the related Guarantees, (b) Liens securing Indebtedness permitted to be
incurred under Credit Facilities, including any letter of credit relating thereto, that was permitted by the terms of this Indenture to be incurred pursuant to clause (1) of Section 4.09(b) and (c) Liens incurred to secure Obligations
in respect of any Indebtedness permitted to be incurred pursuant to Section 4.09 hereof; provided that, with respect to Liens securing Obligations permitted under this clause (c), at the time of incurrence and after giving

calculation is being made shall occur, in each case with such pro forma adjustments to Indebtedness and EBITDA as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of
Fixed Charge Coverage Ratio would be no greater than 5.0 to 1.0.  
 Any Lien which is granted to secure the Notes under this
Section 4.12 shall be discharged at the same time as the discharge of the Lien (other than through the exercise of remedies with respect thereto) that gave rise to the obligation to so secure the Notes. 
  

	 	Section 4.13	Corporate Existence. 

 Subject to Article 5
hereof, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in
accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Issuer and its
Restricted Subsidiaries; provided that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Issuer in good faith
shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole. 
  

	 	Section 4.14	Offer to Repurchase upon Change of Control. 

 (a) If
a Change of Control occurs, unless the Issuer has previously or concurrently mailed a redemption notice with respect to all the outstanding Notes as described under Section 3.07 hereof and will redeem all of the outstanding Notes pursuant
thereto, the Issuer shall make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, subject to the right of Holders of the Notes of record on the relevant Record Date to receive interest due on the
relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuer shall send notice of such Change of Control Offer by first-class mail, with a copy to the Trustee, to each Holder of Notes to the address of such Holder
appearing in the security register with a copy to the Trustee or otherwise in accordance with the procedures of DTC, with the following information: 
 (1) that a Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment by the Issuer; 

 

 87 

 (2) the purchase price and the purchase date, which will be no earlier than 30 days nor
later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that
any Note not properly tendered will remain outstanding and continue to accrue interest; 
 (4) that unless the Issuer defaults
in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with
the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day
preceding the Change of Control Payment Date; 
 (6) that Holders shall be entitled to withdraw their tendered Notes and their
election to require the Issuer to purchase such Notes; provided that the Paying Agent receives, not later than the close of business on the expiration date of the Change of Control Offer, a telegram, facsimile transmission or letter setting
forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; 
 (7) that the Holders whose Notes are being repurchased only in part will be issued new Notes and such new Notes will be equal in principal
amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must be equal to $2,000 or an integral multiple of $1,000 in excess thereof; and 
 (8) the other instructions, as determined by the Issuer, consistent with this Section 4.14, that a Holder must follow. 
 The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. If
(a) notice is mailed in a manner herein provided and (b) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the
validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict
with the provisions of this Section 4.14, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by virtue thereof. 
  

 88 

 (b) On the Change of Control Payment Date, the Issuer shall, to the extent permitted by law, 

(A) accept for payment all Notes issued by it or portions thereof properly tendered pursuant to the Change of Control Offer;

 (B) deposit with the Paying Agent an amount equal to the aggregate Change of Control Payment in respect of all Notes or
portions thereof so tendered; and 
 (C) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so
accepted together with an Officer’s Certificate to the Trustee stating that such Notes or portions thereof have been tendered to and purchased by the Issuer. 
 (c) The Paying Agent shall promptly mail to each Holder the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a
new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 (d) The Issuer shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change
of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at
the time of making of the Change of Control Offer. 
 (e) Other than as specifically provided in this Section 4.14, any purchase
pursuant to this Section 4.14 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06 hereof.

 (a) if the Notes or such Guarantor’s Guarantee is subordinated in right of payment to such Indebtedness, the Guarantee under the
supplemental indenture shall be subordinated to such Restricted Subsidiary’s guarantee with respect to such Indebtedness substantially to the same extent as the Notes are subordinated to such Indebtedness; and 
 (b) if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Guarantee, any
such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s
Guarantee; and 
  

 89 

 (2) such Restricted Subsidiary waives, and shall not in any manner whatsoever claim or
take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against TCEH or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee; 
 provided that this Section 4.15 shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a

 (a) such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity
(after giving effect to any applicable grace periods) or relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such
Indebtedness to become due prior to its stated maturity; and

60 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; 
  

 93

a Significant Subsidiary), in a proceeding in which the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), is to be adjudicated bankrupt or insolvent; 

(ii) appoints a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Issuer or any Significant

effect, other than by reason of the termination of this Indenture or the release of any such Guarantee in accordance with this Indenture. 
  

 94 

 (b) In the event of any Event of Default specified in clause (4) of Section 6.01(a) hereof,
such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the
Holders, if within 20 days after such Event of Default arose: 
 (1) the Indebtedness or guarantee that is the basis for such
Event of Default has been discharged; or 
 (2) the holders thereof have rescinded or waived the acceleration, notice or
action (as the case may be) giving rise to such Event of Default; or

Default has been cured. 
  

	 	Section 6.02	Acceleration. 

 If any Event of Default (other than
an Event of Default specified in clause (6) or (7) of Section 6.01(a) hereof) occurs and is continuing under this Indenture, 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 to be due and payable immediately. Upon the effectiveness of such declaration, such principal and interest shall be due and payable
immediately. The Trustee shall have no obligation to accelerate the Notes if and so long as a committee of its Responsible Officers in good faith determines acceleration is not in the best interest of the Holders of the Notes. 
 Notwithstanding the foregoing, in the case of an Event of Default arising under clause (6) or (7) of Section 6.01(a) hereof, all
outstanding Notes shall be due and payable immediately without further action or notice. 
 Required Holders of at least a majority in
principal amount of the Required Debt by written notice to the Trustee may on behalf of all of the Required Holders waive any existing Default and its consequences under this 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) and rescind any acceleration with respect to the Notes and its consequences (so long as such rescission would not conflict with any judgment of a court of competent
jurisdiction). 
  

	 	Section 6.03	Other Remedies. 

 If an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the
extent permitted by law. 
  

	 	Section 6.04	Waiver of Past Defaults. 

 The Required Holders of
at least a majority in principal amount of the Required Debt by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its 

  

 95 

 
consequences hereunder, except a continuing Default in the payment of the principal of, premium, if any, Additional Interest, if any, or interest on, any
Note held by a non-consenting Holder and rescind any acceleration with respect to the Notes and its consequences (provided such rescission would not conflict with any judgment of a court of competent jurisdiction); provided, subject to
Section 6.02 hereof, that such Required Holders of at least a majority in principal amount of the Required Debt may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon. 
  

	 	Section 6.05	Control by Majority. 

 The Required Holders of at
least a majority in principal amount of the Required Debt may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however,
may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability. 
  

	 	Section 6.06	Limitation on Suits. 

 Subject to Section 6.07
hereof, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has
previously given the Trustee notice that an Event of Default is continuing; 
 (2) Required Holders of at least 30% in
aggregate principal amount of the Required Debt have requested the Trustee to pursue the remedy; 
 (3) Holders of the Notes
have offered the Trustee reasonable security or indemnity against any loss, liability or expense; 
 (4) the Trustee has not
complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and 
 (5) the
Required Holders of at least a majority in aggregate principal amount of the Required Debt have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note. 
  

	 	Section 6.07	Rights of Holders of Notes to Receive Payment. 

 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and Additional Interest, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an Asset Sale Offer or a Change of Control Offer), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent
of such Holder. 
  

 96 

	 	Section 6.08	Collection Suit by Trustee. 

 If an Event of Default
specified in Section 6.01(a)(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium, if
any, and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  

	 	Section 6.09	Restoration of Rights and Remedies. 

 If the Trustee
or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in
every such case, subject to any determination in such proceedings, the Issuer, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the
Holders shall continue as though no such proceeding has been instituted. 
  

	 	Section 6.10	Rights and Remedies Cumulative. 

 Except as
otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  

	 	Section 6.11	Delay or Omission Not Waiver. 

 No delay or omission
of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

	 	Section 6.12	Trustee May File Proofs of Claim. 

 The Trustee is
authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes including the Guarantors), its creditors or its property and shall be entitled and
empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee 

  

 97 

 
under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on,
and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any Plan of Reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any Plan of Reorganization, arrangement, adjustment or composition affecting the Notes or the rights
of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  

	 	Section 6.13	Priorities. 

 If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in the following order:

Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

(ii) to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and Additional Interest, if any, and
interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and Additional Interest, if any, and interest, respectively; and 
 (iii) to the Issuer or to such party as a court of competent jurisdiction shall direct including a Guarantor, if applicable. 

The Trustee may fix a Record Date and payment date for any payment to Holders of Notes pursuant to this Section 6.13. 
  

	 	Section 6.14	Undertaking for Costs. 

 In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to
pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made
by the party litigant. This Section 6.14 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 ARTICLE 7 
 TRUSTEE 

 

	 	Section 7.01	Duties of Trustee. 

 (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the
conduct of such person’s own affairs. 
  

 98 

 (b) Except during the continuance of an Event of Default: 
 (i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only
those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

except that: 
 (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

any Holder of the Notes unless such Holder shall have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. 
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law. 
  

	 	Section 7.02	Rights of Trustee. 

 (a) The Trustee may
conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer,
personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

 99

or negligence of any agent or attorney appointed with due care. 
 (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. 
 (e) Unless
otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by an Officer of the Issuer. 
 (f) None of the provisions of this Indenture shall require the Trustee to expend or risk its own funds or otherwise to incur any liability, financial or otherwise, in the performance of any of its duties hereunder, or
in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it. 
 (g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 
 (h) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but
not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 (i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of
its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

pay Additional Interest, the Issuer will provide written notice to the Trustee of the Issuer’s obligation to pay Additional Interest no later than 15 days prior to the next Interest Payment Date, which notice shall set forth the amount of the
Additional Interest to be paid by the Issuer. The Trustee shall not at any time be under any duty or responsibility to any Holders to determine whether the Additional Interest is payable and the amount thereof. 
  

	 	Section 7.03	Individual Rights of Trustee. 

 The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee
acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to
Sections 7.10 and 7.11 hereof. 
  

 100 

	 	Section 7.04	Trustee’s Disclaimer. 

 The Trustee shall not
be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the
Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital
herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
  

	 	Section 7.05	Notice of Defaults. 

 If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default within 90 days after it occurs. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on
any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. The
Trustee shall not be deemed to know of any Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee at the Corporate Trust Office of the
Trustee. 
  

	 	Section 7.06	Reports by Trustee to Holders of the Notes. 

 Within
60 days after each May 15, beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that
complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall
comply with Trust Indenture Act Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by Trust Indenture Act Section 313(c). 
 A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Issuer and filed with the SEC and each stock exchange on which the Notes are listed in accordance with Trust Indenture
Act Section 313(d). The Issuer shall promptly notify the Trustee when the Notes are listed on any stock exchange. 
  

	 	Section 7.07	Compensation and Indemnity. 

 The Issuer and the
Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in writing from time to time. The Trustee’s compensation
shall not be limited by any law on compensation of a trustee of an express trust. The Issuer and the Guarantors, jointly and severally, shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses
incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee for, and hold the Trustee harmless against, any and all loss, damage,
claims, liability or expense (including attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture
against the Issuer or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any 

  

 101 

 
Holder, the Issuer or any Guarantor, or liability in connective with the acceptance, exercise or performance of any of its powers or duties hereunder). The
Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee may
have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful
misconduct, negligence or bad faith. 
 The obligations of the Issuer under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee. 
 Notwithstanding anything to the contrary in
Section 4.12 hereof, to secure the payment obligations of the Issuer and the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in
trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. 
 When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(a)(6) or (7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel)
are intended to constitute expenses of administration under any Bankruptcy Law. 
 The Trustee shall comply with the provisions of Trust
Indenture Act Section 313(b)(2) to the extent applicable. 
  

	 	Section 7.08	Replacement of Trustee. 

 A resignation or removal
of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Trustee may resign at any time by giving 30 days prior written
notice of such resignation to the Issuer and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and
the Issuer in writing. The Issuer may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof; 
 (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

 (c) a custodian or public officer takes charge of the Trustee or its property; or 
 (d) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority
in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuer’s expense), the Issuer or the Holders of at least 10% in principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  

 102 

 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails
to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided, all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding
replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
  

	 	Section 7.09	Successor Trustee by Merger, etc. 

 If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. 
  

	 	Section 7.10	Eligibility; Disqualification. 

 There shall at all
times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to
supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5). The Trustee
is subject to Trust Indenture Act Section 310(b). 
  

	 	Section 7.11	Preferential Collection of Claims Against Issuer. 

 The Trustee is subject to Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act
Section 311(a) to the extent indicated therein. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
  

	 	Section 8.01	Option to Effect Legal Defeasance or Covenant Defeasance. 

 The Issuer may, at its option and at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 
  

	 	Section 8.02	Legal Defeasance and Discharge. 

 Upon the
Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have
been discharged from their obligations with respect to all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this 

  

 103 

 
purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes,
which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations
under such Notes and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: 
 (a) the rights of Holders of Notes to receive payments in respect of the principal of,
premium, if any, and interest on the Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof; 
 (b) the Issuer’s obligations with respect to Notes concerning issuing temporary Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment
and money for security payments held in trust; 
 (c) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuer’s
obligations in connection therewith; and 
 (d) this Section 8.02. 
 Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof. 
  

	 	Section 8.03	Covenant Defeasance. 

 Upon the Issuer’s
exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations
under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 hereof and clauses (3) and (4) of Section 5.01(a), Sections 5.01(c) and 5.01(d) hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that
such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon
the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(a)(3), 6.01(a)(4),
6.01(a)(5), 6.01(a)(6) (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are Significant Subsidiaries), 6.01(a)(7) (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are
Significant Subsidiaries) and 6.01(a)(8) hereof shall not constitute Events of Default. 
  

 104

with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent
public accountants, to pay the principal of, premium, if any, and interest due on the Notes on the stated maturity date or on the redemption date, as the case may be, of such principal, premium, if any, or interest on such Notes and the Issuer must
specify whether such Notes are being defeased to maturity or to a particular redemption date; 
 (2) in the case of Legal
Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, 
 (a) the Issuer has received from, or there has been published by, the United States Internal Revenue Service a ruling, or 
 (b) since the Issue Date, there has been a change in the applicable U.S. federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the
Holders of the Notes will not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance,
the Issuer shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the Notes will not recognize income, gain or loss for U.S.
federal income tax purposes as a result of such Covenant Defeasance and will be subject to such tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous
deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit; 
 (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the TCEH
Senior Secured Facilities or any other material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to
be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith); 
  

 105 

 (6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect

the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or any Guarantor or others; and 
 the Issuer shall
have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the Legal
Defeasance or the Covenant Defeasance, as the case may be, have been complied with. 
  

	 	Section 8.05	Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. 

 Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium and Additional Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities
deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
 Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the request of the
Issuer any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  

	 	Section 8.06	Repayment to Issuer. 

 Subject to any applicable
abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium and Additional Interest, if any, or interest on any Note and remaining unclaimed for
two years after such principal, and premium and Additional Interest, if any, or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of
such Note shall thereafter look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease. 
  

 106 

	 	Section 8.07	Reinstatement. 

 If the Trustee or Paying Agent is
unable to apply any United States dollars or Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided that if the Issuer makes any payment of principal of, premium and Additional Interest, if any, or interest on
any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER

  

	 	Section 9.01	Without Consent of Holders of Notes. 

 Notwithstanding Section 9.02 of this Indenture, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Guarantees, at any time after the Issue Date, without the consent of any Holder:

 (1) to cure any ambiguity, omission, mistake, defect or inconsistency;

 (6) to add covenants for the benefit of the Holders or to surrender any right or power conferred upon the Issuer or any Guarantor;

 (7) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the
Trust Indenture Act;

Notes; 
 (12) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes as
permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of the Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in Notes being
transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer Notes; or 
 (13) to mortgage, pledge, hypothecate or grant any other Lien in favor of the Trustee for the benefit of the Holders of the Notes, as

series of debt of the Issuer constituting Required Debt in accordance with this Indenture. 
 Upon the request of the Issuer accompanied by a
resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Sections 7.02 and 12.04 hereof, the Trustee shall join with the Issuer
and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with the
addition of a Guarantor under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, and delivery of an
Officer’s Certificate. 
  

	 	Section 9.02	With Consent of Holders of Notes. 

 Except as
provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes and the Guarantees with the consent of the Required Holders of at least a majority in principal amount of the
Required Debt including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Required Debt, and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default
(other than a Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture, the Notes or the Guarantees may be waived with the consent of the Required Holders of at least a majority in principal amount of the Required Debt other than Required Debt beneficially owned by the Issuer or its
Affiliates (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Required Debt). Section 2.08 hereof and Section 2.09 hereof shall determine which Notes are considered to be
“outstanding” for the purposes of this Section 9.02. 
 Upon the request of the Issuer accompanied by a resolution of its
board of directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of 

  

 108 

 
evidence satisfactory to the Trustee of the consent of the Required Holders of at least a majority in principal amount of the Required Debt as aforesaid, and
upon receipt by the Trustee of the documents described in Sections 7.02 and 12.04 hereof, the Trustee shall join with the Issuer in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
 It shall not be necessary for the consent of the Required Holders of the Required Debt under this Section 9.02 to approve the particular form of any
proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or
waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 
 Without the
consent of each affected Holder of Notes, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of such Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed final maturity of any such Note or alter or waive the provisions with respect to the
redemption of such Notes (other than provisions relating to Section 3.09, Section 4.10 and Section 4.14 hereof to the extent that any such amendment or waiver does not have the effect of reducing the principal of or changing the fixed
final maturity of any such Note or altering or waiving the provisions with respect to the redemption of such Notes); 
 (3)
reduce the rate of or change the time for payment of interest on any Note; 
 (4) waive a Default in the payment of principal
of or premium, if any, or interest on the Notes, except a rescission of acceleration of the Notes by the Required Holders of at least a majority in aggregate principal amount of the Required Debt and a waiver of the payment default that resulted
from such acceleration, or in respect of a covenant or provision contained in this Indenture or any Guarantee which cannot be amended or modified without the consent of all Holders; 
 (5) make any Note payable in money other than that stated therein; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments
of principal of or premium, if any, or interest on the Notes; 
 (7) make any change in these amendment and waiver provisions;

 (8) impair the right of any Holder to receive payment of principal of, or interest on such Holder’s Notes on or after
the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; 
  

 109 

 (9) make any change to or modify the ranking provisions of this Indenture or the Notes
that would adversely affect the Holders; or 
 (10) except as expressly permitted by this Indenture, modify the Guarantees of
any Significant Subsidiary in any manner adverse to the Holders of the Notes. 
  

	 	Section 9.03	Compliance with Trust Indenture Act. 

 Every
amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the Trust Indenture Act as then in effect. 
  

	 	Section 9.04	Revocation and Effect of Consents. 

 Until an
amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date
the waiver, supplement or amendment becomes effective. Except as provided in the last paragraph of Section 9.02 hereof, an amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

 The Issuer may, but shall not be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any
amendment, supplement, or waiver. If a Record Date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such Record Date (or their duly designated proxies), and only such Persons, shall be entitled to consent to
such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such Record Date. No such consent shall be valid or effective for more than 120 days after such Record Date
unless the consent of the requisite number of Holders has been obtained. 
  

	 	Section 9.05	Notation on or Exchange of Notes. 

 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of a Issuer Authentication
Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new
Note shall not affect the validity and effect of such amendment, supplement or waiver. 
  

	 	Section 9.06	Trustee to Sign Amendments, etc. 

 The Trustee shall
sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment,
supplement or waiver until the board of directors approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition
to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such
amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to 

  

 110 

 
customary exceptions, and complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, no Opinion of Counsel will be
required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture. 
  

	 	Section 9.07	Payment for Consent. 

 Neither the Issuer nor any
Affiliate of the Issuer shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Required Holder of Required Debt for or as an inducement to any consent, waiver or amendment of
any of the terms or provisions of the Required Debt unless such consideration is offered to all Required Holders and is paid to all Required Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents
relating to such consent, waiver or agreement. 
 ARTICLE 10 
 GUARANTEES 
  

	 	Section 10.01	Guarantee. 

 Subject to this Article 10, each
of the Guarantors hereby, jointly and severally, fully and unconditionally guarantees 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 this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: (a) 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 (b) 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 shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this 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. Each Guarantor hereby waives 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 and covenants that this Guarantee shall not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture. 
 Each Guarantor also agrees to pay any and all costs and expenses (including
reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. 
 If any
Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors 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. 
  

 111 

 Each Guarantor agrees that it 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. Each Guarantor further agrees that, as between the Guarantors, 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 hereof 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 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by
the Guarantors for the purpose of this Guarantee. The Guarantors 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 the Guarantees.

 Each 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 or Guarantees, 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 Notes 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. 
 In case any provision of any 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. 
 The Guarantee issued by any Guarantor shall be a senior unsecured obligation of such
Guarantor. The Guarantees shall rank equally in right of payment with all existing and future Senior Indebtedness of the Guarantor. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each
Guarantor. 
 Each payment to be made by a Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature. 
  

	 	Section 10.02	Limitation on Guarantor Liability. 

 Each Guarantor,
and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the
obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such 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 such other Guarantor under this Article 10, result in the obligations of such Guarantor under its
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Indenture to a
contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance
with GAAP. 
  

 112 

	 	Section 10.03	Execution and Delivery. 

 To evidence its Guarantee
set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer or person holding an equivalent title. 
 Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding the absence
of the endorsement of any notation of such Guarantee on the Notes. 
 If an Officer whose signature is on this Indenture no longer holds that
office at the time the Trustee authenticates the Note, the Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee,
after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors. 
 If required by Section 4.15 hereof, the Issuer shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 10, to the extent applicable. 
  

	 	Section 10.04	Subrogation. 

 Each Guarantor shall be subrogated to
all rights of Holders of Notes against the Issuer in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 10.01 hereof; provided that, if an Event of Default has occurred and is continuing, no Guarantor
shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under this Indenture or the Notes shall have been paid in full. 
  

	 	Section 10.05	Benefits Acknowledged. 

 Each Guarantor acknowledges
that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Guarantee are knowingly made in contemplation of such benefits.

  

	 	Section 10.06	Release of Guarantees. 

 A Guarantee by a Guarantor
shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Issuer or the Trustee is required for the release of such Guarantor’s Guarantee, upon: 
 (1) (a) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of such Guarantor (including any sale, exchange or
transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary or all or substantially all the assets of such Guarantor which sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture;

  

 113 

 (b) the release or discharge of the guarantee under the TCEH Senior Secured Facilities or
of the guarantee by such Guarantor that resulted in the creation of such Guarantee, except a discharge or release by or as a result of payment under such guarantee; 
 (c) the designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in compliance with Section 4.07
hereof and the definition of “Unrestricted Subsidiary” hereunder; or 
 (d) the exercise by Issuer of its Legal
Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the Issuer’s obligations under this Indenture being discharged in accordance with the terms of this Indenture; and 
 (2) such Guarantor delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for in this Indenture relating to such transaction have been complied with. 
 ARTICLE 11 
 SATISFACTION AND DISCHARGE 
  

	 	Section 11.01	Satisfaction and Discharge. 

 This Indenture shall
be discharged and shall cease to be of further effect as to all Notes, when either: 
 (1) all such Notes theretofore
authenticated and delivered, except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust, have been delivered to the Trustee for cancellation; or 
 (2) (A) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption
or otherwise, shall become due and payable within one year or may be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the
Issuer, and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination
thereof, in such amounts as shall be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any,
and accrued interest to the date of maturity or redemption; 
 (B) no Default (other than that resulting from borrowing funds
to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect to the Indenture or the Notes shall have occurred and be
continuing on the date of such deposit or shall occur as a result of such deposit, and such deposit will not result in a breach or violation of, or constitute a default under, the TCEH Senior Secured Facilities or any other material agreement or
instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar and
simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith); 
  

 114 

 (C) the Issuer has paid or caused to be paid all sums payable by it under this Indenture;
and 
 (D) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of
the Notes at maturity or the redemption date, as the case may be. 
 In addition, the Issuer must deliver an Officer’s Certificate and
an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subclause (A) of clause (2) of this Section 11.01, the provisions of Section 11.02 and
Section 8.06 hereof shall survive. 
  

	 	Section 11.02	Application of Trust Money. 

 Subject to the
provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either
directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment
such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to
Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium and Additional Interest, if any, or interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to
the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 [Back of Note] 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Texas Competitive Electric Holding Company LLC, a Texas limited liability company and TCEH Finance, Inc., a Texas corporation (collectively, the
“Issuers”), promise to pay interest on the principal amount of this Note at 10.25% per annum from October 31, 2007 until maturity and shall pay Additional Interest, if any, payable pursuant to the
Registration Rights Agreement referred to below. The Issuer will pay interest and Additional Interest, if any, semi-annually in arrears on May 1 and November 1 of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each, an “Interest Payment Date”) without interest accruing on the amount then so payable from such day that is not a Business Day until such Business Day. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of issuance. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time
to time on demand at the interest rate on the Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any
applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes and Additional
Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the April 15 and October 15 (whether or not a Business Day), next preceding the Interest Payment Date, even if such Notes are canceled after
such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of the 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 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 Notes the Holders of which shall have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. 
 (3) PAYING AGENT AND
REGISTRAR. Initially, The Bank of New York, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to the Holders. The Issuer or
any of its Subsidiaries may act in any such capacity. 
 (4) INDENTURE. The Issuer issued the Notes
under an Indenture, dated as of October 31, 2007 (the “Indenture”), among the Issuer, the Guarantors named therein and the Trustee. This Note is one of a duly authorized issue of notes of the Issuer designated as its 10.25%
Senior Notes due 2015. The Issuer shall be entitled to issue Additional Notes pursuant to Sections 2.01 and 4.09 of the Indenture. The Notes (including any Exchange Notes issued in exchange therefor) and any Additional Notes shall be treated as
a single class of securities under the Indenture. In addition, the Notes will be treated along with certain other senior unsecured debt of the Issuer as a single class for amendments and waivers and for taking certain other actions. The terms of the
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 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 Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date, with the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the sum of

such redemption occurs within 90 days of the date of closing of each such Equity Offering. Notice of any redemption upon any Equity Offerings may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuer’s
discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.

any, to the date of purchase (the “Change of Control Payment”), subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. The Change of Control
Offer shall be made in accordance with Section 4.14 of the Indenture. 
 (b) If the Issuer or any of its Restricted Subsidiaries
consummates an Asset Sale, within ten Business Days of each date that the aggregate amount of Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes, and if required or permitted by the terms of any Senior
Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of
$1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date
fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Issuer may use any remaining Excess Proceeds to make Restricted Payments to the extent permitted by clause (16) of Section 4.07(b) of the Indenture. If the aggregate principal amount of Notes or such Senior Indebtedness
surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or
such Senior Indebtedness tendered.

by the Indenture. The Issuer need not exchange or register the transfer of any Notes or portion of Notes selected for redemption, except for the unredeemed portion of any Notes being redeemed in part. Also, the Issuer need not exchange or register
the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 
 (10) PERSONS
DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

 A-1-5 

 (12) 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 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 Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if any, Additional
Interest, if any, or interest on, any of the Notes 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 (5) 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. 
 (13) AUTHENTICATION. This Note shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee. 
 (14)

Interest, if any (as defined in the Registration Rights Agreement).

WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

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 Notes or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

 [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
Texas limited liability company (“TCEH” ), TCEH Finance, Inc., a Texas Corporation (together with TCEH, the “Issuer”), and The Bank of New York, as trustee (the “Trustee”). 
 WITNESSETH 
 WHEREAS, each of the Issuer and
the Guarantors (as defined in the Indenture referred to below) has heretofore executed and delivered to the Trustee an Indenture (the “Indenture”), dated as of October 31, 2007, providing for the issuance of an unlimited
aggregate principal amount of 10.25% Senior Notes due 2015 (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 and interest, premium and Additional Interest, if any, on the Notes will 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 will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will 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 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. 
  

 D-2 

 (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 obligation of such Guaranteeing Subsidiary, ranking equally in right of payment with all existing and future Senior Indebtedness of the Guaranteeing Subsidiary, will be effectively subordinated to all Secured
Indebtedness of such Guaranteeing Subsidiary to the extent of the value of the collateral securing such indebtedness. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness 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.

Subsidiaries are bound or affected, except, in all cases, for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect (other than
violations pursuant to clauses (i) or (iii) (with respect to federal and state securities laws)). Neither the Company nor any of its Subsidiaries is required under federal, state, foreign or local law, rule or regulation to obtain any

of the environment including, without limitation, all requirements pertaining to reporting, licensing, permitting, controlling, investigating or remediating emissions, discharges, releases or threatened releases of hazardous substances, chemical
substances, pollutants, contaminants or toxic substances, materials or wastes, whether solid, liquid or gaseous in nature, into the air, surface water, 

  

 5

limitations, restrictions, conditions, standards, requirements, schedules and timetables required or imposed under all Environmental Laws, except for those that the failure of which to comply with would not reasonably be expected to have a Material
Adverse Effect. Except for such instances as would not individually or in the aggregate have a Material Adverse Effect, there are no past or present events, conditions, circumstances, incidents, actions or omissions relating to or in any way
affecting the Company or its Subsidiaries that violate any Environmental Law or that to the Company’s knowledge, give rise to any environmental liability or otherwise form the basis of any claim, action, demand, suit, proceeding, hearing, study
or investigation (i) under any Environmental Law, or (ii) based on or related to the manufacture, processing, distribution, use, treatment, storage (including without limitation underground storage tanks), disposal, transport or handling,
or the emission, discharge, release or threatened release of any hazardous substance. 
 (t) Books and Records; Internal Accounting

the nature of all transactions giving rise to the obligations or accounts receivable of the Company or any Subsidiary. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient, in the judgment of the
Company’s board of directors, to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate actions are taken with respect to any differences.

be reasonably likely to have a Material Adverse Effect, (i) the Company and each of its Subsidiaries have performed all obligations required to be performed by them to date under any existing written or oral contract, instrument, agreement,
commitment, obligation, plan or arrangement, filed or required to be filed with the Commission (the “Material Agreements”), (ii) neither the Company nor any of its Subsidiaries has received any notice of default under any
Material Agreement and, (iii) to the best of the Company’s knowledge, neither the Company nor any of its Subsidiaries is in material default under any Material Agreement now in effect.

there are no loans, leases, agreements, contracts, royalty agreements, management contracts or arrangements or other continuing transactions between (a) the Company, any Subsidiary or any of their respective customers or suppliers on the one
hand, and (b) on the other hand, any officer, employee, consultant or director of the Company, or any of its Subsidiaries, or any person owning at least 5% of the outstanding capital stock of the Company or any Subsidiary or any member of the
immediate family of such officer, employee, consultant, director or stockholder or any corporation or other entity controlled by such officer, employee, consultant, director or stockholder, or a member of the immediate family of such officer,
employee, consultant, director or stockholder which, in each case, is required to be disclosed in the Commission Documents or in the Company’s most recently filed definitive proxy statement on Schedule 14A, that is not so disclosed in

Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the
performance of the obligations of any other Purchaser under the Transaction Documents. The Company acknowledges that the decision of each Purchaser to purchase Securities pursuant to this Agreement has been made by such Purchaser independently of
any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the
Company or of its Subsidiaries which may have made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person)
relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be
deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the
transactions contemplated by the Transaction Documents. The Company acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or
requested to do so by the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the
Transaction Documents or the transactions contemplated hereby or thereby. 
 (cc) No Integrated Offering. Neither the Company, nor any
of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Securities
pursuant to this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Securities pursuant to Regulation D and Rule 506 thereof under the Securities Act, or
any applicable exchange-related stockholder approval provisions, nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings. The
Company does not have any registration statement pending registration before the Commission or currently under the Commission’s review. 
 (dd) Sarbanes-Oxley Act. The Company is in material compliance with the applicable provisions of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the rules and regulations promulgated thereunder, that
are effective and intends to comply with other applicable provisions of the Sarbanes-Oxley Act, and the rules and regulations promulgated thereunder, upon the effectiveness of such provisions.

 (ee) Dilutive Effect. The Company understands and acknowledges that pursuant to the Statement of
Designation the number of Conversion Shares may increase in certain circumstances. The Company further acknowledges that it is obligated to issue Conversion Shares, in accordance with this Agreement and the Statement of Designation, regardless of
the dilutive effect that such issuance may have on the ownership interest of other stockholders of the Company except to the extent that the Company’s obligations conflict with the rules and regulations of The Nasdaq Stock Market. 

(ff) Delisting Notification. Except as disclosed in the Commission Documents, the Company has not received notice (written or oral) from The
Nasdaq Stock Market LLC to the effect that the Company is not in compliance with the listing or maintenance requirements of such exchange. 
 Section 2.2 Representations and Warranties of the Purchasers. Each of the Purchasers hereby represents and warrants to the Company with respect solely to itself and not with respect to any other Purchaser as follows as of the
date hereof and as of the Closing Date: 
 (a) Organization and Standing of the Purchasers. If the Purchaser is an entity, such
Purchaser is a corporation, limited liability company or partnership duly incorporated or organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization. 
 (b) Authorization and Power. Each Purchaser has the requisite power and authority to enter into and perform the Transaction Documents and to
purchase the Securities being sold to it hereunder. If the Purchaser is an entity, the execution, delivery and performance of the Transaction Documents by such Purchaser and the consummation by it of the transactions contemplated hereby have been
duly authorized by all necessary corporate, limited liability company or partnership action, and no further consent or authorization of such Purchaser or its Board of Directors, stockholders, members or partners, as the case may be, is required.
When executed and delivered by the Purchasers, each of the Transaction Documents shall constitute valid and binding obligations of each Purchaser enforceable against such Purchaser in accordance with their terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable
principles of general application. 
 (c) Acquisition for Investment. Each Purchaser is purchasing the Securities solely for its own
account and not with a view to or for sale in connection with any distribution. Each Purchaser acknowledges that it (i) has such knowledge and experience in financial and business matters such that such Purchaser is capable of evaluating the
merits and risks of such Purchaser’s investment in the Company, (ii) is able to bear the financial risks associated with an investment in the Securities and (iii) has been given full access to such records of the Company and the
Subsidiaries and to the officers of the Company and the Subsidiaries as it has deemed necessary or appropriate to conduct its due diligence investigation. 
 (d) Rule 144. Each Purchaser understands that the Securities are restricted securities and must be held indefinitely unless such Securities are registered under the Securities Act or an exemption from
registration is available. Each Purchaser acknowledges that such person is familiar with Rule 144 of the rules and regulations of the Commission, as amended, promulgated pursuant to the Securities Act (“Rule 144”), and that such
Purchaser has been advised that Rule 144 permits resales only under certain circumstances. Each Purchaser understands that to the extent that Rule 144 is not available, such Purchaser will be unable to sell any Securities without either registration
under the Securities Act or the existence of another exemption from such registration requirement. 
 (e) General. Each Purchaser
understands that the Securities are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and the Company is relying upon the truth and accuracy of the
representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Securities. Each Purchaser
understands that no United States federal or state agency or any government or governmental agency has passed upon or made any recommendation or endorsement of the Securities, the Conversion Shares or the Warrant Shares. Commencing on the date that
the Purchasers were initially contacted regarding an investment in the Securities, none of the Purchasers has engaged in any short sale of the Common Stock and will not engage in any short sale of the Common Stock prior to the consummation of the
transactions contemplated by this Agreement. 
  

 9 

 (f) No General Solicitation. Each Purchaser acknowledges that the Securities were not offered to
such Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any
newspaper, magazine, or similar media, or broadcast over television or radio, or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications. Each Purchaser, in making the decision to purchase
the Securities, has relied upon independent investigation made by it and has not relied on any information or representations made by third parties. 
 (g) Reservation of Shares. Each Purchaser acknowledges and agrees that the Company does not have sufficient shares of Common Stock authorized under its Articles to reserve for the issuance of the Conversion
Shares or the Warrant Shares. 
 (h) Accredited Investor. Each Purchaser is an “accredited investor” (as defined in Rule 501
of Regulation D of the Securities Act), and such Purchaser has such experience in business and financial matters that it is capable of evaluating the merits and risks of an investment in the Securities. Such Purchaser is not required to be
registered as a broker-dealer under Section 15 of the Exchange Act and such Purchaser is not a broker-dealer. Each Purchaser acknowledges that an investment in the Securities is speculative and involves a high degree of risk. Each Purchaser has
executed and delivered to the Company the Accredited Investor Questionnaire attached hereto as Exhibit E (the “Questionnaire”) and represents and warrants that the information contained therein is true, correct and complete.

 (i) Certain Fees. Except as set forth on Schedule 2.1(p), the Purchasers have not employed any broker or finder or incurred
any liability for any brokerage or investment banking fees, commissions, finders’ structuring fees, financial advisory fees or other similar fees in connection with the Transaction Documents. 
 (j) Independent Investment. No Purchaser has agreed to act with any other Purchaser for the purpose of acquiring, holding, voting or disposing of
the Securities purchased hereunder for purposes of Section 13(d) under the Exchange Act, and each Purchaser is acting independently with respect to its investment in the Securities. 
 ARTICLE III

“Issuable Maximum”) as required by the Nasdaq Marketplace Rules then in effect (the “Nasdaq Proposal”), and (3) to the extent that making the Shares convertible into shares of Common Stock as well as the
issuance of the Warrants may constitute a change of control under the Nasdaq Marketplace Rules, the approval of such change of control (the “Control Proposal” and together with the Articles Amendment and the Nasdaq Proposal, the
“Proposals”). 
 (j) Officers and Directors. The Company covenants and agrees that all of the officers and directors
of the Company that hold shares of Common Stock shall vote in favor of the Proposals. 
 (k) Warrants. 
 (i) In the event that the Company’s shareholders approve all the Proposals, on the next Trading Day following the Next Annual
Meeting, the Company shall issue Warrants to each Purchaser, in the amounts and at the exercise prices set forth in Exhibit A-1.

Date but in no event more than two (2) Trading Days following the Closing Date, which Press Release and Form 8-K shall be subject to prior review and comment by the Purchasers. “Trading Day” means any day during which the
principal exchange on which the Common Stock is traded shall be open for trading. 
 (o) Disclosure of Material Information. The
Company covenants and agrees that neither it nor any other person acting on its behalf has provided or will provide any Investor Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public
information, unless prior thereto such Investor Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Investor Purchaser shall be relying on the
foregoing representations in effecting transactions in securities of the Company. 
 (p) Pledge of Securities. The Company
acknowledges and agrees that the Securities, the Conversion Shares and the Warrant Shares may be pledged by a Purchaser in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities, the
Conversion Shares or the Warrant Shares. The pledge of the Securities, the Conversion Shares or the Warrant Shares shall not be deemed to be a transfer, sale or assignment of the Securities, the Conversion Shares or the Warrant Shares, and no
Purchaser effecting a pledge of the Securities, the Conversion Shares or the Warrant Shares shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other
Transaction Document; provided that a Purchaser and its pledgee shall be required to comply with the 

  

 12 

 
provisions of Article V hereof in order to effect a sale, transfer or assignment of the Securities, the Conversion Shares or the Warrant Shares to such
pledgee. At the Purchasers’ expense, the Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities, the Conversion Shares or the Warrant Shares may reasonably request in connection with a pledge of the
Securities, the Conversion Shares or the Warrant Shares to such pledgee by a Purchaser. 
 (q) Amendments. The Company shall not amend
or waive any provision of the Articles or Bylaws of the Company in any way that would adversely affect exercise rights, voting rights, conversion rights, prepayment rights or redemption rights of the holder of the Shares. 
 (r) Distributions. So long as any Shares remain outstanding, the Company agrees that it shall not (i) declare or pay any dividends or make
any distributions to any holder(s) of Common Stock or (ii) purchase or otherwise acquire for value, directly or indirectly, any Common Stock or other equity security of the Company. 
 (s) Reservation of Shares. The Company shall at all times reserve and keep available out of its authorized but unissued Common Stock, solely for
issuance upon the conversion of the Shares, one hundred percent (100%) of the applicable number of shares of Common Stock as is expressly permitted to be issued from time to time upon the conversion of the Shares outstanding at the time,
subject to the limitations on conversion set forth in the Statement of Designation. 
 (t) Subsequent Financings. During the period
commencing on the Closing Date and ending on first anniversary hereof, the Company covenants and agrees to promptly notify (in no event later than five (5) days after making or receiving an applicable offer) in writing (a “Rights
Notice”) each Purchaser of the terms and conditions of any proposed offer or sale to, or exchange with (or other type of distribution to), any third party, of Common Stock or any securities convertible, exercisable or exchangeable into
Common Stock, including convertible debt securities (a “Subsequent Financing”). The Rights Notice shall describe, in reasonable detail, the proposed Subsequent Financing, the proposed closing date of the Subsequent Financing, which
shall be within thirty (30) calendar days from the date of the Rights Notice, including, without limitation, all of the terms and conditions thereof and proposed definitive documentation to be entered into in connection therewith. The Rights
Notice shall provide each Purchaser an option (the “Rights Option”) during the ten (10) Trading Days following delivery of the Rights Notice (the “Option Period”) to inform the Company whether such Purchaser
will purchase up to its pro rata portion for the securities being offered in such Subsequent Financing on the same, absolute terms and conditions as contemplated by such Subsequent Financing (the “First Refusal Rights”). If any
Purchaser elects not to participate in such Subsequent Financing, the other Purchasers may participate on a pro-rata basis so long as such participation in the aggregate does not exceed the total Purchase Price hereunder. The Company has no
obligation to allow the Purchasers to participate in any Subsequent Financing in excess of the Purchase Price. For purposes of this Section, all references to “pro rata” means, for any Purchaser electing to participate in such Subsequent
Financing, the percentage obtained by dividing (x) such Purchaser’s respective portion of the Purchase Price, as set forth on Exhibit A hereto, by (y) the total Purchase Price. If the Company does not receive notice of exercise
of the Rights Option from the Purchasers within the Option Period, the Company shall have the right to close the Subsequent Financing on the scheduled closing date with a third party; provided that all of the material terms and conditions of
the closing are substantially the same as those provided to the Purchasers in the Rights Notice. If the closing of the proposed Subsequent Financing does not occur on that date, any closing of the contemplated Subsequent Financing or any other
Subsequent Financing shall be subject to all of the provisions of this Section 3.1(r), including, without limitation, the delivery of a new Rights Notice. 
 (u) No Impairment. At all times after the date hereof, the Company will not take or permit any action, or cause or permit any subsidiary to take or permit any action that impairs or adversely affects the rights
of the Purchasers under the Transaction Documents. 
 (v) Fundamental Changes. In addition to any other rights provided by law or set
forth herein, from and after the date of this Agreement and for so long as any Shares remain outstanding, except as set forth on Schedule 3.1(v) the Company shall not without first obtaining the approval (by vote or written consent, as
provided by law) of the Purchasers holding a majority of the outstanding Shares: 
  

 13 

 (i) purchase, redeem (other than pursuant to equity incentive agreements with non-officer
employees giving the Company the right to repurchase shares upon the termination of services) or set aside any sums for the purchase or redemption of, or declare or pay any dividend (including a dividend payable in stock of the Company) or make any
other distribution with respect to, any shares of capital stock or any other securities that are convertible into or exercisable for such stock; 
 (ii) change the nature of the Company’s business to any business which is fundamentally distinct and separate from the business currently conducted by the Company; or 
 (iii) cause or permit any subsidiary of the Company directly or indirectly to take any actions described in clauses (i) through
(iii) above, other than issuing securities to the Company. 
 Section 3.2 Purchaser Covenant. Each Purchaser covenants with
the Company, which covenants are for the benefit of the Company and its permitted assignees: 
 (a) Short Sales. Such Purchaser shall
not engage in any short sale of the Common Stock. 
 (b) Ownership Percentage. Notwithstanding anything to the contrary set forth in
this Agreement or the Statement of Designation, at no time may each Purchaser convert all or a portion of its Shares or exercise all or a portion of its Warrants, if the number of shares of Common Stock to be issued pursuant to such conversion or
exercise would exceed, when aggregated with all other shares of Common Stock owned by such Purchaser at such time, the number of shares of Common Stock which would result in the such Purchaser beneficially owning (as determined in accordance with
Section 13(d) and Section 16(b) of the Exchange Act and the rules thereunder) more than 9.99% of all of the Common Stock outstanding at such time.

 ARTICLE V 
 TRANSFERABILITY; LEGENDS

 Section 5.1 Transferability of the Securities. Subject to compliance with any applicable securities laws and
Section 5.2 the Securities, the Conversion Shares and the Warrant Shares may be transferred by a holder without the consent of the Corporation. The certificates representing the Securities, the Conversion Shares and the Warrant Shares are
exchangeable at the principal office of the Corporation for certificates representing the same aggregate number of shares as set forth therein. 
 Section 5.2 Legends. Each certificate representing the Securities, the Conversion Shares and the Warrant Shares shall be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend
required by applicable state securities or “blue sky” laws): 
 [NEITHER] THESE SECURITIES [NOR THE SECURITIES INTO WHICH THESE
SECURITIES ARE [CONVERTIBLE][EXERCISABLE]] HAVE [NOT] BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE 

  

 15 

 
SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS. NOTWITHSTANDING THE FOREGOING, THESE SECURITIES AND THE SECURITIES
ISSUABLE UPON [EXERCISE] [CONVERSION] OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT SECURED BY SUCH SECURITIES. 
 The Company agrees to issue or reissue certificates representing any of the Conversion Shares and the Warrant Shares, without the legend set forth above if at such time, prior to making any transfer of any such Conversion Shares or Warrant
Shares, such holder thereof shall give written notice to the Company describing the manner and terms of such transfer and removal as the Company may reasonably request. Such proposed transfer and removal will not be effected until: (a) either
(i) the Company has received an opinion of counsel reasonably satisfactory to the Company, to the effect that the registration of the Conversion Shares or Warrant Shares under the Securities Act is not required in connection with such proposed
transfer, (ii) a registration statement under the Securities Act covering such proposed disposition has been filed by the Company with the Commission and has become effective under the Securities Act, (iii) the Company has received other
evidence reasonably satisfactory to the Company that such registration and qualification under the Securities Act and state securities laws are not required, (iv) the holder provides the Company with reasonable assurances that such security can
be sold pursuant to Rule 144 under the Securities Act or (v) the holder certifies in writing to the Company that the Securities may be sold under Rule 144(k) of the Securities Act; and (b) either (i) the Company has received an
opinion of counsel reasonably satisfactory to the Company, to the effect that registration or qualification under the securities or “blue sky” laws of any state is not required in connection with such proposed disposition,
(ii) compliance with applicable state securities or “blue sky” laws has been effected, or (iii) the holder provides the Company with reasonable assurances that a valid exemption exists with respect thereto. The Company will
respond to any such notice from a holder within three (3) business days. In the case of any proposed transfer under this Section 5.1, the Company will use reasonable efforts to comply with any such applicable state securities or “blue
sky” laws, but shall in no event be required, (x) to qualify to do business in any state where it is not then qualified, (y) to take any action that would subject it to tax or to the general service of process in any state where it is
not then subject, or (z) to comply with state securities or “blue sky” laws of any state for which registration by coordination is unavailable to the Company. The restrictions on transfer contained in this Section 5.1 shall be in
addition to, and not by way of limitation of, any other restrictions on transfer contained in any other section of this Agreement. Each Purchaser, severally and not jointly, agrees that the removal of the restrictive legend from certificates
representing the Warrant Shares or the Conversion Shares as set forth in this Section 5.1 is predicated upon the Company’s reliance that the Purchaser will sell such Warrant Shares or Conversion Shares pursuant to the registration
requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom. Whenever a certificate representing the Conversion Shares or Warrant Shares is required to be issued to a Purchaser without a
legend, in lieu of delivering physical certificates representing the Conversion Shares or Warrant Shares, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities
Transfer program, the Company shall use its reasonable best efforts to cause its transfer agent to electronically transmit the Conversion Shares or Warrant Shares to a Purchaser by crediting the account of such Purchaser’s Prime Broker with DTC
through its Deposit Withdrawal Agent Commission (“DWAC”) system (to the extent not inconsistent with any provisions of this Agreement). 
 ARTICLE VI 
 INDEMNIFICATION 
 Section 6.1 General Indemnity. The Company agrees to indemnify and hold harmless the Purchasers (and their respective directors, officers,
affiliates, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the
Purchasers as a result of any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein. The maximum aggregate liability of each Purchaser pursuant to its indemnification obligations under this Article VI
shall not exceed the portion of the Purchase Price paid by such Purchaser hereunder. 
 Section 6.2 Indemnification Procedure.
Any party entitled to indemnification under this Article VI (an “indemnified party”) will give written notice to the indemnifying party of any matter giving rise to a 

  

 16 

 
claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve
the indemnifying party of its obligations under this Article VI except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action, proceeding or claim is brought against an indemnified
party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnifying party a conflict of interest between it and the indemnified party
exists with respect to such action, proceeding or claim (in which case the indemnifying party shall be responsible for the reasonable fees and expenses of one separate counsel for the indemnified parties), to assume the defense thereof with counsel
reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will not contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any
indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then
the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim,
proceeding or action, the indemnified party’s costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall
cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party
which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to
defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim
or proceeding effected without its prior written consent. Notwithstanding anything in this Article VI to the contrary, the indemnifying party shall not, without the indemnified party’s prior written consent, settle or compromise any claim or
consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party,
identified by name or category of persons, of a release from all liability in respect of such claim. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against
the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law. No indemnifying party will be liable to the indemnified party under this Agreement to the extent, but only to the extent
that a loss, claim, damage or liability is attributable to the indemnified party’s breach of any of the representations, warranties or covenants made by such party in this Agreement or in the other Transaction Documents. 
 ARTICLE VII 
 MISCELLANEOUS 

 Section 7.1 Fees and Expenses. Each party shall pay the fees and expenses of its advisers, counsel, accountants and other
experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all transfer agent fees, stamp taxes and other taxes and duties
levied in connection with the issuance of any Securities. 
 Section 7.2 Specific Performance; Consent to Jurisdiction; Venue.

 (a) The Company and the Purchasers acknowledge and agree that irreparable damage would occur in the event that any of the provisions of
this Agreement or the other Transaction Documents were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent or cure
breaches of the provisions of this Agreement or the other Transaction Documents and to enforce specifically the terms and provisions hereof or thereof, this being in addition to any other remedy to which any of them may be entitled by law or equity.

 (b) The parties agree that venue for any dispute arising under this Agreement will lie exclusively in the state or federal courts located
in New York County, New York, and the parties irrevocably waive any right to raise forum non conveniens or any other argument that New York is not the proper venue. The parties 

  

 17 

 
irrevocably consent to personal jurisdiction in the state and federal courts of the state of New York. The Company and each Purchaser consent to process
being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing in this Section 7.2 shall affect or limit any right to serve process in any other manner permitted by law. The Company and the Purchasers hereby agree that the prevailing party in any suit, action or proceeding arising
out of or relating to the Securities, this Agreement or the other Transaction Documents, shall be entitled to reimbursement for reasonable legal fees from the non-prevailing party. The parties hereby waive all rights to a trial by jury. 

Section 7.3 Entire Agreement; Amendment. This Agreement and the Transaction Documents contain the entire understanding and agreement of
the parties with respect to the matters covered hereby and, except as specifically set forth herein or in the other Transaction Documents, neither the Company nor any Purchaser make any representation, warranty, covenant or undertaking with respect
to such matters, and they supersede all prior understandings and agreements with respect to said subject matter, all of which are merged herein. No provision of this Agreement may be waived or amended other than by a written instrument signed by the
Company and the Purchasers holding at least a majority of the Shares. Any amendment or waiver effected in accordance with this Section 7.3 shall be binding upon each Purchaser (and their permitted assigns) and the Company.

any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right
hereunder in any manner impair the exercise of any such right accruing to it thereafter. No consideration shall 

  

 18 

 
be offered or paid to any Purchaser to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same
consideration is also offered to all of the parties to the Transaction Documents. This provision constitutes a separate right granted to each Purchaser by the Company and shall not in any way be construed as the Purchasers acting in concert or as a
group with respect to the purchase, disposition or voting of Securities or otherwise. 
 Section 7.6 Headings. The article,
section and subsection headings in this Agreement are for convenience only and shall not constitute a part of this Agreement for any other purpose and shall not be deemed to limit or affect any of the provisions hereof. 
 Section 7.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and
assigns. After the Closing, the assignment by a party to this Agreement of any rights hereunder shall not affect the obligations of such party under this Agreement. Subject to Section 5.1 hereof, the Purchasers may assign the Securities and its
rights under this Agreement and the other Transaction Documents and any other rights hereto and thereto without the consent of the Company. 
 Section 7.8 No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns and is not for the benefit of, nor may any provision hereof be
enforced by, any other person. 
 Section 7.9 Governing Law. This Agreement shall be governed by and construed in accordance with
the internal laws of the State of New York, without giving effect to any of the conflicts of law principles which would result in the application of the substantive law of another jurisdiction. This Agreement shall not be interpreted or construed
with any presumption against the party causing this Agreement to be drafted. 
 Section 7.10 Survival. The representations and
warranties of the Company and the Purchasers shall survive the execution and delivery hereof and the Closing until the first anniversary of the Closing Date, except the agreements and covenants set forth in Articles I, III, V, VI and VII of this
Agreement shall survive the execution and delivery hereof and the Closing, and shall terminate and be of no further force or effect when a majority of the Shares are no longer outstanding. 
 Section 7.11 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and
the same instrument and shall become effective when counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. The Parties agree that the delivery
of this Agreement may be effected by means of an exchange of facsimile or as an attachment to an electronic mail message in “pdf” or similar format. 
 Section 7.12 Publicity. The Company agrees that it will not disclose, and will not include in any public announcement, the names of the Purchasers without the consent of the Purchasers, which consent shall
not be unreasonably withheld or delayed, or unless and until such disclosure is required by law, rule or applicable regulation, including without limitation any disclosure pursuant to a registration statement registering the Conversion Shares and
the Warrant Shares, and then only to the extent of such requirement. 
 Section 7.13 Severability. The provisions of this
Agreement are severable and, in the event that any court of competent jurisdiction shall determine that any one or more of the provisions or part of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision or part of a provision of this Agreement and this Agreement shall be reformed and construed as if such invalid or illegal or
unenforceable provision, or part of such provision, had never been contained herein, so that such provisions would be valid, legal and enforceable to the maximum extent possible. 
  

 19 

 Section 7.14 Further Assurances. From and after the date of this Agreement, upon the request
of the Purchasers or the Company, the Company and each Purchaser shall execute and deliver such instruments, documents and other writings as may be reasonably necessary or desirable to confirm and carry out and to effectuate fully the intent and
purposes of this Agreement and the other Transaction Documents.
