subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but prior to or simultaneously with the event for which the calculation 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 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. 
 For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (as determined in accordance with GAAP) that have been made by the

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 the Issuer may designate.

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 Senior 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.

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. 
 (f) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Senior Note may do so with regard to all
or any part of the principal amount of such Senior 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 notice given or action taken by a

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.

Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Senior Note shall be dated the date of its authentication. The Senior Notes shall be in minimum denominations of $2,000 and integral multiples of
$1,000 in excess thereof, subject to the issuance of certificated PIK Notes as set forth in Exhibit A-2. 
 (b) Global
Notes. Senior Notes issued in global form shall be substantially in the form of Exhibit A-1 (in the case of Senior Cash Pay Notes) or Exhibit A-2 (in the case of the Senior Toggle Notes) hereto (including, in each case,
the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Senior Notes issued in definitive form shall be substantially in the form of Exhibit A-1 (in the case of Senior
Cash Pay Notes) or Exhibit A-2 (in the case of the Senior Toggle Notes) 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 Senior 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 Senior Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Senior 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 Senior 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. Senior 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 Senior 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 

  

 43 








 
amount of the 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 Senior Notes that may be authenticated and delivered under this Indenture is unlimited. 
 The terms and provisions contained in the Senior 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 Senior Note conflicts with the express provisions of
this Indenture, the provisions of this Indenture shall govern and be controlling. 
 The Senior Notes shall be subject to repurchase by the
Issuer pursuant to an Asset Sale Offer as provided in Section 4.10 hereof or a Change of Control Offer as provided in Section 4.14 hereof. The Senior Notes shall not be redeemable other than as provided in Article 3 hereof.

to or consent of the Holders and shall be consolidated with and form a single class with the Initial Senior Notes and shall have the same terms as to status, redemption or otherwise as the Initial Senior Notes; provided that the Issuer’s
ability to issue Additional Senior Notes shall be subject, among other things, to the Issuer’s compliance with Section 4.09 hereof; provided further that in connection with the payment of PIK Interest, the Issuer may, without
the consent of the Holders (and without regard to any restrictions or limitations set forth in Section 4.09 hereof), increase the outstanding principal amount of the Senior Toggle Notes or issue PIK Notes. The Senior Cash Pay Notes and the
Senior Toggle Notes are each a separate series of Senior Notes but will be treated as a single class of securities under this Indenture, except as otherwise stated herein. As a result, Holders of each series of Senior Notes will not have separate
rights to, among other things, give notice of Defaults or to direct the Trustee to exercise remedies during an Event of Default or otherwise. Except as described under Article 9 hereof, the Senior Notes offered by the Issuer, the PIK Notes and any
Additional Senior Notes subsequently issued under this Indenture will be treated as a single class for all purposes under this Indenture, including, among other things, waivers, amendments, redemptions and offers to purchase. Unless the context
requires otherwise, references to “Senior Notes” for all purposes under this Indenture include any PIK Notes and Additional Notes that are actually issued, and references to “principal amount” of the Senior Notes includes any
increases in the principal amount of the outstanding Senior Notes as a result of a PIK Payment. Any Additional Senior Notes shall be issued with the benefit of an indenture supplemental to this Indenture.

interests, and an adjustment shall be made on the books and records of the Trustee (if it is then the Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Custodian, to reflect such increase. On any Interest
Payment Date on which the Issuer pays PIK Interest by issuing definitive PIK Notes, the principal amount of any such PIK Notes issued to any Holder, for the relevant interest period as of the relevant Record Date for such Interest Payment Date,
shall be rounded up to the nearest $1.00. 
 The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Senior
Notes. An authenticating agent may authenticate Senior 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.

	 	Section 2.04	Paying Agent to Hold Money in Trust. 

 The Issuer
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, Additional
Interest if any, or cash interest on the Senior 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

 (h) Cancellation and/or
Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such
Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who
will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Senior Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on
such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

 (i) General Provisions Relating to Transfers and Exchanges. 
 (i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and
Definitive Notes upon receipt of a Issuer Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.07, 2.10, 3.06, 3.09,
4.10, 4.14 and 9.05 hereof). 
 (iii) Neither the Registrar nor the Issuer shall be required to register the transfer of or
exchange any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior 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 Senior Notes during a period beginning at the opening of business 15 days before the day of any selection of
Senior 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 Senior Note so selected for redemption in whole or in part, except the
unredeemed portion of any Senior Note being redeemed in part; or (C) to register the transfer of or to exchange a Senior Note between a Record Date and the next succeeding Interest Payment Date. 
  

 57 








 (vi) Prior to due presentment for the registration of a transfer of any Senior Note, the
Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Senior Note is registered as the absolute owner of such Senior Note for the purpose of receiving payment of principal of (and premium, if any) and interest (including
Additional Interest, if any) on such Senior 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 Senior 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 Senior Notes of any authorized denomination or denominations of a like
aggregate principal amount. 
 (viii) At the option of the Holder, Senior Notes may be exchanged for other Senior Notes of any
authorized denomination or denominations of a like aggregate principal amount upon surrender of the Senior 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 Senior Notes. 

 If any mutilated Senior
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 Senior Note, the Issuer shall issue and the Trustee, upon receipt of a
Issuer Authentication Order, shall authenticate a replacement Senior 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 Senior Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a
Senior Note. 
 Every replacement Senior 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 Senior Notes duly issued hereunder. 
  

	 	Section 2.08	Outstanding Senior Notes. 

 The Senior Notes
outstanding at any time are all the Senior 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 Senior Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Senior
Note. 
 If a Senior 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 Senior Note is held by a protected purchaser. 
  

 58 








 If the principal amount of any Senior 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 Senior Notes payable on that date, then on and after that date such Senior 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 Senior Notes have concurred in any direction, waiver or consent, any Senior 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 Senior Notes that a Responsible Officer of the Trustee knows are so owned, shall be so disregarded. Senior 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 Senior Notes and that the pledgee is not the
Issuer or any obligor upon the Senior Notes or any Affiliate of the Issuer or of such other obligor. 
  

	 	Section 2.10	Temporary Senior Notes. 

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

	 	Section 2.11	Cancellation. 

 The Issuer at any time may deliver
Senior Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Senior 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 Senior Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Senior Notes (subject to the record retention
requirement of the Exchange Act). Certification of the destruction of all cancelled Senior Notes shall be delivered to the Issuer upon the Issuer’s written request. The Issuer may not issue new Senior Notes to replace Senior Notes that it has
paid or that have been delivered to the Trustee for cancellation. 
  

	 	Section 2.12	Defaulted Cash Interest. 

 If the Issuer defaults in
a payment of cash interest on the Senior Notes, it shall pay the defaulted cash interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted cash interest, to the Persons who are Holders on a subsequent special
record date, in each case at the rate provided in the Senior Notes and in Section 4.01 hereof. The Issuer shall notify the Trustee in writing of the amount of defaulted cash interest proposed to be paid on each Senior Note and the date of the


  

 59 








 
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 cash 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 cash 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 cash 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
Senior Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Senior Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Senior Note.

  

	 	Section 2.13	CUSIP and ISIN Numbers. 

 The Issuer in issuing the
Senior 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 Senior Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Senior 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.

	 	Section 3.01	Notices to Trustee. 

 If the Issuer elects to redeem
the Senior Cash Pay Notes or the Senior Toggle Notes, as the case may be, pursuant to Section 3.07 hereof, it shall furnish to the Trustee, at least two 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 60 days before a Redemption Date, an Officer’s Certificate setting forth (i) the paragraph or subparagraph of such Senior Notes and/or Section of this Indenture

	 	Section 3.02	Selection of Senior Notes to Be Redeemed or Purchased. 

 (a) If less than all of the Senior Cash Pay Notes or the Senior Toggle Notes, as the case may be, are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Senior Notes of such series to be redeemed
or purchased (a) if the Senior Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Senior 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 DTC. 
  

 60 








 In the event of partial redemption or purchase by lot, the particular Senior 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 Senior Notes not previously called for redemption or purchase. 
 The Trustee shall promptly notify the Issuer in writing of the Senior Notes selected for redemption or purchase and, in the case of any Senior Note
selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Senior Notes and portions of Senior Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; no Senior Notes
of $2,000 or less can be redeemed in part, except that if all of the Senior Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Senior 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 Senior Notes called for redemption or purchase also apply to portions of Senior 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 Senior 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, Section 3.07(c) and Section 3.07(d) hereof, notices of redemption may not be conditional. 
 The notice shall
identify the Senior Notes to be redeemed and shall state: 
 (a) the Redemption Date; 
 (b) the redemption price; 
 (c) if any
Senior Note is to be redeemed in part only, the portion of the principal amount of that Senior Note that is to be redeemed and that, after the Redemption Date upon surrender of such Senior Note, a new Senior Note or Senior Notes in principal amount
equal to the unredeemed portion of the original Senior Note representing the same indebtedness to the extent not redeemed will be issued in the name of the Holder of the Senior Notes upon cancellation of the original Senior Note; 
 (d) the name and address of the Paying Agent; 
 (e) that Senior 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 Senior Notes called for redemption ceases to accrue on and after the Redemption Date; 
 (g) the paragraph or subparagraph of the Senior Notes and/or Section of this Indenture pursuant to which the Senior 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
Senior Notes; and 
  

 61 








 (i) if in connection with a redemption pursuant to Section 3.07(c) or 3.07(d) 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, Senior 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(c) and 3.07(d)
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, failure to give such notice by mail or any defect in the notice to the Holder
of any Senior Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Senior Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to
accrue on Senior Notes or portions of Senior 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 Senior 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 Senior 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 Senior Notes or the portions of Senior Notes called for
redemption or purchase. If a Senior 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 Senior Note was registered at the close of business on such Record Date. If any Senior 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 Senior Notes and in Section 4.01 hereof. 
  

	 	Section 3.06	Senior Notes Redeemed or Purchased in Part. 

 Upon
surrender of a Senior 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 Senior Note equal in
principal amount to the unredeemed or unpurchased portion of the Senior Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that each new Senior Cash Pay Note and Senior Toggle Note (other
than PIK Notes) will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is

Officer’s Certificate is required for the Trustee to authenticate such new Senior Note.

discount” (as defined in Section 1273(a)(1) of the Code) on the Senior Toggle Notes then outstanding up to the Optional Interest Repayment Amount (each such redemption, an “Optional Interest Repayment”). The

discount” (as defined in Section 1273(a)(1) of the Code) with respect to the applicable Senior Toggle Note, over (b) an amount equal to the product of (i) the “issue price” (as defined in Sections 1273(b) and 1274(a) of

for exchange and where notices and demands to or upon the Issuer in respect of the Senior Notes and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee. 
 The Issuer may also from time to time designate one or more other offices or agencies where the
Senior Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Issuer of its obligation to
maintain an office or agency in the Borough of Manhattan, the City of New York, for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency.

SEC on the Issuer’s website (or that of any of its parent companies) or providing such reports to the Trustee within 15 days after the time the Issuer would be required to file such information with the SEC if it were a non-accelerated filer
subject to Section 13 or 15(d) of the Exchange Act, containing the financial information (including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section) that would be required to be
included in such reports, subject to exceptions consistent with the presentation of financial and other information in the Offering Memorandum, to the extent filed within the times specified above. 
 Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its obligations set forth under this
Section 4.03 for purposes of Section 6.01(3) hereof until 60 days after the date any report is due pursuant to this Section 4.03.

 (b) When any Default has occurred and is continuing under this Indenture, or if the Trustee or the holder of any other evidence of Indebtedness of the
Issuer or any Subsidiary gives any notice or takes any other action with respect to a claimed Default, the Issuer shall promptly (which shall be no more than five (5) Business Days) deliver to the Trustee by registered or certified mail or by

“Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Issuer’s Capital Stock or purchase for cash or otherwise acquire for cash any Capital Stock of the Issuer or any direct or indirect parent of the Issuer for the purpose of paying any cash dividend or making any cash distribution to, or
acquiring Capital Stock of any direct or indirect parent of the Issuer for cash from, the Investors, or guarantee any Indebtedness of any Affiliate of the Issuer for the purpose of paying such dividend, making such distribution or so acquiring such
Capital Stock to or from the Investors, in each case by means of utilization of the cumulative Restricted Payment credit provided by Section 4.07(a) hereof, or the exceptions provided by clauses (1), (7) or (11) of
Section 4.07(b) hereof or clauses (8), (10) or (13) of the definition of “Permitted Investments”, unless (x) at the time and after giving effect to such payment, the Consolidated Leverage Ratio of the Issuer would be
equal to or less than 7.00 to 1.00 and (y) such payment is otherwise in compliance with this Section 4.07.

 (5) any agreement or other instrument of a Person acquired by the Issuer or any Restricted Subsidiary
in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the
property or assets of the Person and its Subsidiaries, so acquired; 
 (6) contracts for the sale of assets, including
customary restrictions with respect to a Subsidiary of the Issuer pursuant to an agreement that has been entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Subsidiary;

Closing Date or (ii) any such encumbrance or restriction does not prohibit (except upon a default thereunder) the payment of dividends or loans in an amount sufficient, as determined by the Issuer in good faith, to make scheduled payments of
cash interest of the Senior Notes when due; 
  

 77

refinancing of the contracts, instruments or obligations referred to in clauses (1) through (11) of this Section 4.08(b); provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings are, in the good faith judgment of the Issuer, no more restrictive with respect to such encumbrance and other restrictions taken as a whole than those prior to such amendment, modification, restatement, renewal,
increase, supplement, refunding, replacement or refinancing; 
 (13) restrictions created in connection with any Receivables
Facility for the benefit of the Issuer or any of its Restricted Subsidiaries that, in the good faith determination of the Issuer, are necessary or advisable to effect the transactions contemplated under such Receivables Facility; and

similar agreement to which the Issuer or any Restricted Subsidiary of the Issuer is a party entered into in the ordinary course of business; provided that such agreement prohibits the encumbrance solely to the property or assets of the Issuer
or such Restricted Subsidiary that are the subject of such agreement, the payment rights arising thereunder and/or the proceeds thereof and does not extend to any other asset or property of the Issuer or such Restricted Subsidiary or the assets or
property of any other Restricted Subsidiary.

 (a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or

issue shares of Preferred Stock, if the Fixed Charge Coverage Ratio on a consolidated basis for the Issuer and its Restricted Subsidiaries’ most recently ended four fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.00 to 1.00 and (ii) TCEH or any of its Restricted Subsidiaries may incur
Indebtedness (including Acquired Indebtedness), issue shares of Disqualified Stock and issue shares of Disqualified Stock and issue shares of Preferred Stock, if the Fixed Charge Coverage Ratio on a consolidated basis for TCEH and its Restricted

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 incurred by any Person acquiring all or any
portion of such business, assets or a Subsidiary for the purpose of financing such acquisition; provided, however, that such Indebtedness is not reflected on the balance sheet of the Issuer, or any of its Restricted Subsidiaries
(contingent obligations referred to in a footnote to financial statements and not otherwise reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this clause (6));

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 

  

 79 








 
or any other subsequent transfer of any such Indebtedness (except to the Issuer or another Restricted Subsidiary) shall be deemed, in each case, to be an
incurrence of such Indebtedness not permitted by this clause (7);

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 the Issuer or another Restricted Subsidiary) shall
be deemed, in each case, to be an incurrence of such Indebtedness not permitted by this clause (8); 
 (9) shares of Preferred
Stock of a Restricted Subsidiary issued to the Issuer or another Restricted Subsidiary; provided that any 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 the Issuer 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 the Issuer in its reasonable discretion acting in good faith) and (ii) in the case of speculative commodity Hedging Obligations, such

the extent such net cash proceeds or cash have not been applied pursuant to such clauses to make Restricted Payments or to make other Investments, payments or exchanges pursuant to Section 4.07(b) hereof or to make Permitted Investments (other
than Permitted Investments specified in clauses (1) and (3) of the definition thereof) and (b) Indebtedness or Disqualified Stock of the Issuer and Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted

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) from and after the first date on which the Issuer or such Restricted
Subsidiary could have incurred such Indebtedness, Disqualified Stock or Preferred Stock under Section 4.09(a) hereof without reliance on this clause (12)(b)); 
  


 80 








 (13) the incurrence or issuance by the Issuer or any Restricted Subsidiary of
Indebtedness, Disqualified Stock or Preferred Stock which serves to refund or refinance any Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted Subsidiary incurred as permitted under Section 4.09(a) hereof and
clauses (2), (3), (4) and (12)(a) of this Section 4.09(b), this clause (13) and clause (14) of this Section 4.09(b) or any Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted

(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 Senior Notes or any Guarantee thereof, such Refinancing Indebtedness is subordinated or pari
passu to the Senior 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

Restricted Subsidiary incurred to finance an acquisition or (y) Persons that are acquired by the Issuer or any Restricted Subsidiary or merged into the Issuer or a Restricted Subsidiary in accordance with the terms of this Indenture;
provided that after giving effect to such acquisition or merger, either 
 (A) in the case of an acquisition by or
merger with the Issuer or any of its Restricted Subsidiaries other than TCEH and its Restricted Subsidiaries, either (a) the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to clause (i) of the Fixed
Charge Coverage Ratio test set forth in Section 4.09(a) hereof, or (b) such Fixed Charge Coverage Ratio of the Issuer and the Restricted Subsidiaries is greater than immediately prior to such acquisition or merger; or 
  

 81 








 (B) in the case of an acquisition by or merger with TCEH or any of its Restricted
Subsidiaries, either (a) TCEH would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to clause (ii) of the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof, or (b) such Fixed Charge
Coverage Ratio of TCEH and its Restricted Subsidiaries is greater than immediately prior to such acquisition or merger; 
 (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 incurrence; 
 (16) Indebtedness of the Issuer 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) (a) any guarantee by the Issuer 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 the Issuer; provided that such
guarantee is incurred in accordance with Section 4.15 hereof; 
 (18) Indebtedness of the Issuer or any of its Restricted
Subsidiaries consisting of (i) the financing of insurance premiums or (ii) take-or-pay obligations contained in supply arrangements, in each case, incurred in the ordinary course of business; and 
 (19) Indebtedness consisting of Indebtedness issued by the Issuer 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 the Issuer or any direct or indirect parent company of the Issuer to the extent described
in clause (4) of Section 4.07(b) hereof. 
 (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 (19) of this Section 4.09(b) or is entitled to be incurred pursuant to Section 4.09(a) hereof, the
Issuer, 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, the Issuer 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 Section 4.09(b)(1) hereof. 
  

 82 








 (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, the Issuer shall not, and shall not permit 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 the Issuer or such Guarantor, as the case may be, unless such Indebtedness is expressly
subordinated in right of payment to the Senior Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Guarantor, as the case may be. 

For purposes of this Indenture, Indebtedness that is unsecured is not deemed to be subordinated or junior to Secured Indebtedness merely because it is
unsecured, and 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) The Issuer shall not, and shall
not permit any of its Restricted Subsidiaries to consummate, directly or indirectly, an Asset Sale, unless: 
 (1) the Issuer
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 the Issuer) 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 the Issuer 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 the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Issuer or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the
Senior Notes or that are owed to the Issuer or an Affiliate of the Issuer, that are assumed by the transferee of any such assets and for which the Issuer and all of its Restricted Subsidiaries have been validly released by all applicable creditors
in writing, 
  

 83 








 (B) any securities received by the Issuer or such Restricted Subsidiary from such
transferee that are converted by the Issuer 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 the Issuer 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, the Issuer 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; 
 (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 Senior 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 under this Section 4.10) to all Holders to purchase their Senior 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, 2017, 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 that is not a Guarantor, other than Indebtedness owed to the Issuer or another Restricted Subsidiary (or any affiliate thereof); 
 provided that, if an offer to purchase any Indebtedness of TCEH or any of its Restricted Subsidiaries is made in accordance with the terms of such
Indebtedness, the obligation to permanently reduce Indebtedness of a Restricted Subsidiary will be deemed to be satisfied to the extent of the amount of the offer, whether or not accepted by the holders thereof, and no Net Proceeds in the amount of
such offer will be deemed to exist following such offer; 
  

 84 








 (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 the Issuer 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 the Issuer 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 the Issuer, 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, the Issuer 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 the Issuer 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. 

Any Net Proceeds from Asset Sales that are not invested or applied as provided and within the time period set forth in the first sentence of
Section 4.10(b) 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 Senior 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 Senior 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 ten 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 Senior 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 for
general corporate purposes, subject to other covenants contained in this Indenture. If the aggregate principal amount of Senior Notes or the Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee
shall select the Senior Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the

Senior 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 such Asset Sale Offer, any Net Proceeds not required to be used
to purchase Senior Notes shall not be deemed Excess Proceeds. 
 (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 Senior 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.

 (4) that unless the Issuer defaults in the payment of the Change of Control Payment, all Senior 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 Senior Notes purchased pursuant to a Change of Control Offer will be

entitled to withdraw their tendered Senior Notes and their election to require the Issuer to purchase such Senior 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

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.

the Issuer and purchases all Senior 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.

attached as Exhibit D hereto, providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Issuer: 
 (a) if the Senior 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 Senior Notes are subordinated to such Indebtedness; and 
 (b) if such Indebtedness is by its express terms subordinated in right of payment to the Senior Notes, 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 Senior Notes; and 
 (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 the Issuer or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee;

hereof, all outstanding Senior Notes shall be due and payable immediately without further action or notice. 
 The Holders of at least a
majority in aggregate principal amount of the Senior Notes by written notice to the Trustee may on behalf of all of the 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 Senior Note (held by a non consenting Holder) and rescind any acceleration with respect to the Senior 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 Senior Notes or to enforce the performance of any provision of the Senior Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Senior Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Senior 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 Holders of at least a
majority in aggregate principal amount of the Senior Notes by notice to the Trustee may on behalf of the Holders of all of the Senior Notes waive any existing Default and its consequences hereunder, except a continuing Default in the payment of the
principal of, premium, if any, Additional Interest, if any, or interest on, any Senior Note held by a non-consenting Holder and rescind any acceleration with respect to the Senior 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 the Holders of a majority in aggregate principal amount of the then outstanding Senior Notes 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. 
  

 96 









	 	Section 6.05	Control by Majority. 

 The Holders of at least a
majority in aggregate principal amount of the Senior Notes 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 Senior 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 Senior Note may pursue any remedy with respect to this Indenture or the Senior Notes unless: 
 (1)
such Holder has previously given the Trustee notice that an Event of Default is continuing; 
 (2) Holders of at least 30% in
aggregate principal amount of the Senior Notes have requested the Trustee to pursue the remedy; 
 (3) Holders of the Senior
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
Holders of at least a majority in aggregate principal amount of the Senior Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 A Holder of a Senior Note may not use this Indenture to prejudice the rights of another Holder of a Senior Note or to obtain a preference or priority
over another Holder of a Senior Note. 
  

	 	Section 6.07	Rights of Holders of Senior Notes to Receive Payment. 

 Notwithstanding any other provision of this Indenture, the right of any Holder of a Senior Note to receive payment of principal, premium, if any, and Additional Interest, if any, and interest on the Senior Note, on or after the respective
due dates expressed in the Senior 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. 
  

	 	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 Senior 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. 
  

 97 









	 	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 Senior 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 Senior 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 Senior Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Senior 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 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 Senior
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. 
  

 98 









	 	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: 
 (i) to the 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 Senior Notes for amounts due and unpaid on the Senior 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 Senior 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 Senior 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 Senior Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Senior
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. 
 (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 

  

 99 








 
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; 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved in a court

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.

 (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. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not

 100 








 (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 Senior 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.

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 Senior 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.

be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Senior Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Senior 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

 101 









	 	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 Senior 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 Senior 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 Senior 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 Senior Notes. 

 Within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, and for so long as Senior Notes remain outstanding, the Trustee shall mail to the Holders of the Senior 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 Senior Notes shall be mailed to the Issuer and filed with the SEC and each stock
exchange on which the Senior Notes are listed in accordance with Trust Indenture Act Section 313(d). The Issuer shall promptly notify the Trustee when the Senior 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 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. 
  

 102 








 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 Senior Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular
Senior 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 Senior 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 Senior 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 Senior Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 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 

  

 103 








 
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.

 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 Senior 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 Senior Notes and Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the
Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Senior 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 Senior 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 Senior Notes to receive payments in respect of the principal of, premium, if any, and interest on the Senior Notes when such
payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof; 
  

 104 








 (b) the Issuer’s obligations with respect to Senior Notes concerning issuing temporary Senior Notes,
registration of such Senior Notes, mutilated, destroyed, lost or stolen Senior 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
Senior Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“Covenant Defeasance”), and the Senior 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 Senior Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Senior 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 Senior 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. 
  

	 	Section 8.04	Conditions to Legal or Covenant Defeasance. 

 The
following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Senior Notes: 
 In order

irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Senior Notes, cash in U.S. dollars, Government Securities, or a combination 

  

 105

premium, if any, and interest due on the Senior 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 Senior Notes and the Issuer must specify whether such Senior
Notes are being defeased to maturity or to a particular redemption date; 
 (2) in the case of Legal Defeasance, the Issuer

 (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 Senior 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 Senior 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 any 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); 
 (6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject to
customary assumptions and exclusions following the deposit, the trust funds will not be subject to the effect of Section 547 of Title 11 of the United States Code; 
 (7) the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer with
the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or any Guarantor or others; and 
  

 106 








 (8) 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 Senior Notes shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Senior 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 Senior 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 Senior 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 Senior 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 Senior 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. 
  

	 	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 Senior 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 Senior Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Senior Notes to receive such payment from the money held by the Trustee or Paying Agent. 
  

 107 








 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
  

	 	Section 9.01	Without Consent of Holders of Senior Notes. 

 Notwithstanding Section 9.02 of this Indenture, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Senior 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; 
 (2) to provide for uncertificated Senior Notes of such series in addition to or in place of certificated Senior Notes; 
 (3) to comply with Section 5.01 hereof; 
 (4) to provide for the assumption of the Issuer’s or any Guarantor’s obligations to the Holders; 
 (5) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under this Indenture of any such Holder; 
 (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

 (8) to evidence and provide for the acceptance and appointment under this Indenture of a successor
Trustee thereunder pursuant to the requirements thereof; 
 (9) to provide for the issuance of Exchange Notes or private
exchange notes, which are identical to Exchange Notes except that they are not freely transferable; 
 (10) to add a Guarantor
under this Indenture; 
 (11) to conform the text of the Indenture, Guarantees or the Senior Notes to any provision of the
“Description of the Notes” section of the Offering Memorandum to the extent such provision in such “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Indenture, Guarantee or Senior
Notes; 
 (12) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Senior
Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of the Senior Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in
Senior 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 Senior Notes; 
  

 108 








 (13) to mortgage, pledge, hypothecate or grant any other Lien in favor of the Trustee for
the benefit of the Holders of the Senior Notes, as security for the payment and performance of all or any portion of the Obligations, in any property or assets; or 
 (14) in the event that PIK Notes are issued in certificated form, to make appropriate amendments to this Indenture to reflect an
appropriate minimum denomination of certificated PIK Notes and establish minimum redemption amounts for certificated PIK Notes. 
 In
addition, notwithstanding Section 9.02 of this Indenture, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture at any time after the Issue Date, without the consent of any Holder, to provide for the issuance of
Additional Senior Notes 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 Senior Notes. 

 Except as
provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Senior Notes and the Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of
the Senior Notes (including Additional Senior Notes) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Senior Notes) 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 Senior Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Senior Notes or the Guarantees may be waived with the consent of the Holders of at least a majority in aggregate principal amount
of the Senior Notes (including Additional Senior Notes) then outstanding voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Senior Notes) other than Senior Notes
beneficially owned by the Issuer or its Affiliates; provided, however, that if any amendment, waiver or other modification will affect only the Senior Cash Pay Notes or Senior Toggle Notes, only the consent of the Holders of at least a
majority in principal amount of the then outstanding Senior Cash Pay Notes or Senior Toggle Notes (and not the consent of at least a majority of all Senior Notes), as the case may be, shall be required. Section 2.08 hereof and Section 2.09
hereof shall determine which Senior 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 evidence satisfactory to the Trustee of the consent of
the Holders of at least a majority in aggregate 

  

 109 








 
principal amount of the Senior Notes 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 Holders of the Senior Notes 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 Senior 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 Senior Notes, an amendment or waiver under this Section 9.02 may not (with
respect to any Senior Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of such Senior 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 Senior Note or alter or waive the provisions with respect to the redemption of such Senior 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 Senior Note or altering or waiving the provisions with respect to the redemption of such Senior Notes); 
 (3) reduce the rate of or change the time for payment of interest on any Senior Note; 
 (4) waive a Default in the payment of principal of or premium, if any, or interest on the Senior Notes, except a rescission of
acceleration of the Senior Notes by the Holders of at least a majority in aggregate principal amount of the Senior Notes 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 Senior
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 Senior 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 Senior 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 Senior Notes; 

 

 110 








 (9) make any change to or modify the ranking provisions of this Indenture or the Senior
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 Senior Notes. 
  

	 	Section 9.03	Compliance with Trust Indenture Act. 

 Every
amendment or supplement to this Indenture or the Senior 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 Senior Note is a continuing consent by the Holder of a Senior Note and every subsequent Holder of a Senior Note or portion of a Senior Note that evidences the same
debt as the consenting Holder’s Senior Note, even if notation of the consent is not made on any Senior Note. However, any such Holder of a Senior Note or subsequent Holder of a Senior Note may revoke the consent as to its Senior 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 Senior Notes. 

 The
Trustee may place an appropriate notation about an amendment, supplement or waiver on any Senior Note thereafter authenticated. The Issuer in exchange for all Senior Notes may issue and the Trustee shall, upon receipt of a Issuer Authentication
Order, authenticate new Senior Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a
new Senior 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 customary 

  

 111 








 
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 Holder of Senior Notes for or as an inducement to any consent, waiver or amendment of any of the
terms or provisions of this Indenture or the Senior Notes unless such consideration is offered to all Holders and is paid to all 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 Senior 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 Senior Notes or the obligations of the Issuer hereunder or thereunder, that: (a) the principal of, interest, premium and Additional Interest, if any, on the Senior 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 Senior 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 Senior 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
Senior Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Senior 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 Senior 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. 
  

 112 








 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 Senior Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by
any obligee on the Senior 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 Senior 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 Senior 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 

  

 113 








 
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. 
  

	 	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 Senior Notes. 
 If an Officer whose signature is on this Indenture no longer
holds that office at the time the Trustee authenticates the Senior Note, the Guarantee shall be valid nevertheless. 
 The delivery of any
Senior 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 Senior 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 Senior 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;

  

 114 








 (b) the release or discharge 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; 
 provided that such Guarantor shall
have delivered 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 Senior Notes, when either: 
 (1) all Senior Notes theretofore
authenticated and delivered, except lost, stolen or destroyed Senior Notes which have been replaced or paid and Senior Notes for whose payment money has theretofore been deposited in trust, have been delivered to the Trustee for cancellation; or

 (2) (A) all Senior 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 Senior 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 Senior 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 this
Indenture or the Senior 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 any 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 

  

 115 








 
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); 
 (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
Senior 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 Senior 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

 [Back of Senior Cash Pay Note] 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Energy Future Holdings Corp., a Texas corporation (the “Issuer”), promises to pay
interest on the principal amount of this Senior Cash Pay Note at 10.875% 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 Senior Cash Pay 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 Senior Cash Pay 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 Senior Cash Pay 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 Senior Cash Pay Notes and
Additional Interest, if any, to the Persons who are registered Holders of Senior Cash Pay Notes at the close of business on the April 15 or October 15 (whether or not a Business Day), as the case may be, next preceding the Interest Payment
Date, even if such Senior Cash Pay 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 Senior Cash Pay 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 Senior Cash Pay Notes under an Indenture, dated as of October 31, 2007 (the “Indenture”), among the Issuer, the Guarantors named therein and the Trustee.
This Senior Cash Pay Note is one of a duly authorized issue of notes of the Issuer designated as its 10.875% Senior Notes due 2017. The Issuer shall be entitled to issue Additional Senior Cash Pay Notes pursuant to Sections 2.01 and 4.09 of the
Indenture. The Senior Cash Pay Notes (including any Exchange Notes issued in exchange therefor) and the Senior Toggle Notes issued under the Indenture (including any Exchange Notes issued in exchange therefor) (collectively, referred to herein as
the “Senior Notes”) are separate series of Senior Notes, but shall be treated as a single class of securities under the Indenture, unless otherwise specified in the Indenture. The terms of the Senior Cash Pay 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 Senior Cash Pay 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 Senior Cash Pay Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

address or otherwise in accordance with the procedures of DTC. Senior Cash Pay Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Senior Cash Pay Notes held by
a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Senior Cash Pay Notes or portions thereof called for redemption.

Change of Control occurs, the Issuer shall make an offer (a “Change of Control Offer”) to each Holder to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Senior
Cash Pay Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Change of Control Payment”), subject
to the right of Holders of Senior Cash Pay 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.

“Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Senior 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

Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Senior Notes or such Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds,
the Trustee shall select the Senior Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Senior Notes or such Senior Indebtedness tendered. 
 (c) 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;

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

 [Back of Senior Toggle Note] 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Energy Future Holdings Corp., a Texas corporation (the “Issuer”), promises to pay
interest on the principal amount of this Senior Toggle Note at a rate per annum set forth below 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 Senior Toggle 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 Senior Toggle 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 Senior Toggle Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 Cash Interest on the Senior Toggle Notes will accrue at a rate of 11.250% per annum and be payable in cash. PIK Interest on the Senior
Toggle Notes will accrue at a rate of 12.000% per annum and be payable (x) with respect to Senior Toggle Notes represented by one or more global notes registered in the name of, or held by, The Depository Trust Company
(“DTC”) or its nominee on the relevant Record Date, by increasing the principal amount of the outstanding global Senior Toggle Note by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to
the nearest $1,000) (or, if necessary, pursuant to the requirements of DTC or otherwise, to authenticate new global Senior Toggle Notes executed by the Issuer with such increased principal amounts) and (y) with respect to Senior Toggle Notes
represented by certificated notes, by issuing PIK Notes in certificated form in an aggregate principal amount equal to the amount of PIK Interest for the applicable period (rounded up to the nearest whole dollar), and the Trustee will, at the
request of the Issuer, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant Record Date, as shown by the records of the register of Holders. In the event that the Issuer elects to pay
Partial PIK Interest for any interest period, each Holder will be entitled to receive Cash Interest in respect of 50% of the principal amount of the Senior Toggle Notes held by such Holder on the relevant Record Date and PIK Interest in respect of
50% of the principal amount of the Senior Toggle Notes held by such Holder on the relevant Record Date. Following an increase in the principal amount of the outstanding global Senior Toggle Notes as a result of a PIK Payment, the global Senior
Toggle Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in certificated form will be dated as of the applicable Interest Payment Date and will bear interest from and after
such date. All Senior Toggle Notes issued pursuant to a PIK Payment will mature on November 1, 2017 and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits as
the Senior Toggle Notes issued on the Issue Date. Any certificated PIK Notes will be issued with the description PIK on the face of such PIK Note. 
 At the end of any “accrual period” (as defined in Section 1272(a)(5) of the Code) ending after the fifth anniversary of the Issue Date (each, an “Optional Interest Repayment Date”), the Issuer may pay in
cash, without duplication, all accrued and unpaid interest, if any, and all accrued but unpaid “original issue discount” (as defined in Section 1273(a)(1) of the Code) on the Senior Toggle Notes then outstanding up to the Optional
Interest Repayment Amount (each such redemption, an “Optional Interest  

  

 A-2-3 








 
Repayment”). The “Optional Interest Repayment Amount” shall mean, as of each Optional Interest Repayment Date, the excess, if
any, of (a) the aggregate amount of accrued and unpaid interest and all accrued and unpaid “original issue discount” (as defined in Section 1273(a)(1) of the Code) with respect to the applicable Senior Toggle Note, over
(b) an amount equal to the product of (i) the “issue price” (as defined in Sections 1273(b) and 1274(a) of the Code) of the applicable Senior Toggle Note multiplied by (ii) the “yield to maturity” (as defined in
the Treasury Regulation Section 1.1272-1(b)(1)(i)) of such Senior Toggle Note, minus (c) $50,000,000. 
 On May 1, 2017, the
Issuer shall repay in full in U.S. Dollars an amount of Senior Toggle Notes equal to $50,000,000. Prepayments of Senior Toggle Notes made pursuant to the preceding sentence shall be made on a pro rata basis based on the aggregate
principal amount of Senior Toggle Notes outstanding. 
 (2) METHOD OF
PAYMENT. For any interest payment period after the initial interest payment period and prior to November 1, 2012, the Issuer may, at its option elect to pay interest on the Senior Toggle Notes: 
 (i) entirely in cash (“Cash Interest”); 
 (ii) entirely by increasing the principal amount of the outstanding Senior Toggle Notes or by issuing PIK Notes (“PIK Interest”); or 
 (iii) on 50% of the outstanding principal amount of the Senior Toggle Notes in cash and on 50% of the outstanding principal amount by increasing the
principal amount of the outstanding Senior Toggle Notes or by issuing PIK Notes (“Partial PIK Interest”). 
 The Issuer must
elect the form of interest payment with respect to each interest period by delivering a notice to the Trustee prior to the beginning of such interest period. The Trustee shall promptly deliver a corresponding notice to the Holder of this Senior
Toggle Note. In the absence of such an election for any interest period, interest on this Senior Toggle Note shall be payable according to the election for the previous interest period. Interest for the first interest payment period commencing on
the Issue Date shall be payable entirely in cash. After November 1, 2012, the Issuer will make all interest payments on this Senior Toggle Note entirely in cash. Notwithstanding anything to the contrary, the payment of accrued interest in
connection with any redemption of Senior Toggle Notes as described under Sections 3.07, 4.10 and 4.14 of the Indenture shall be made solely in cash. 
 The Issuer will pay Cash Interest on the Senior Toggle Notes and Additional Interest, if any, to the Persons who are registered Holders of Senior Toggle Notes at the close of business on the April 15 or
October 15 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Senior Toggle 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. Payments of Cash 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 Senior Toggle 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. 
  

 A-2-4 








 (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.

Toggle Notes under an Indenture, dated as of October 31, 2007 (the “Indenture”), among the Issuer, the Guarantors named therein and the Trustee. This Senior Toggle Note is one of a duly authorized issue of notes of the Issuer
designated as its 11.250%/12.000% Senior Toggle Notes due 2017. The Issuer shall be entitled to issue Additional Senior Toggle Notes pursuant to Sections 2.01 and 4.09 of the Indenture. The Senior Cash Pay Notes (including any Exchange Notes issued
in exchange therefor) and the Senior Toggle Notes issued under the Indenture (including any Exchange Notes issued in exchange therefor) (collectively, referred to herein as the “Senior Notes”) are separate series of Senior Notes,
but shall be treated as a single class of securities under the Indenture, unless otherwise specified in the Indenture. The terms of the Senior Toggle Notes include those stated in the Indenture and those made part of the Indenture by reference to

 EXHIBIT D 
 [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 Energy
Future Holdings Corp., a Texas corporation (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 10.875% Senior Notes due 2017 and 11.250%/12.000% Senior Toggle
Notes due 2017 (together, the “Senior 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 Senior 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 Senior 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 Senior 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 Senior 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 Senior 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 Senior 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 
  

 D-1 








 (ii) in case of any extension of time of payment or renewal of any Senior 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
Senior Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Senior 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 Senior 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 

  

 D-2 








 
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. 
 (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 Senior Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored
or returned by any obligee on the Senior 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 Senior 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
unsecured 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 Senior Notes will be
structurally subordinated to Indebtedness and other liabilities of Subsidiaries of the Issuer that do not Guarantee the Senior Notes, if any.

applicable provisions of the Indenture;
