which the calculation of such ratio is made shall be calculated on a pro forma basis assuming that all such Specified Transactions (and any increase or decrease in Consolidated EBITDA and the component financial definitions used therein

 Whenever pro forma effect is to be given to a Specified Transaction or

expense reductions, other operating improvements and synergies that are reasonably identifiable, factually supportable and projected by the Company in good faith to be reasonably anticipated to be realizable within 18 months after the closing date
of such Specified Transaction or implementation of an operating initiative (provided, that to the extent any such operational changes are not associated with a transaction, such changes shall be limited to those for which all steps have been
taken for realizing such savings and are factually supportable, reasonably identifiable and supported by an Officer’s Certificate delivered to the Trustee) (calculated on a pro forma basis as though such cost savings, operating expense
reductions, other operating improvements and synergies had been realized on the first day of such period as if such cost savings, operating expense reductions, other operating improvements and synergies were realized during the entirety of such
period) relating to such Specified Transaction, net of the amount of actual benefits realized during such period from such actions; provided that any increase in Consolidated EBITDA as a result of cost savings, operating expense reductions,

letter of credit, except to the extent of unreimbursed amounts drawn thereunder, (ii) of Excluded Subsidiaries (but, for the avoidance of doubt, not secured guarantees of such Indebtedness by the Company or the Subsidiary Guarantors) or
(iii) in respect of certain hedging obligations described in the Collateral Trust Agreement.

waived by the Company in its sole discretion), such redemption may not occur and such notice may be rescinded in the event that any or all of such conditions shall not have been satisfied (or waived by the Company in its sole discretion) by the
redemption date, or by the redemption date so delayed.

May 13, 2025, the Company may on any one or more occasions redeem all or a part of the applicable series of Notes, upon not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of
such Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to but excluding the redemption date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest
payment date.

excluding the redemption date, subject to the rights of Holders of such 2024 Notes on the relevant record date to receive interest due on the relevant interest payment date. 

(c) Except pursuant to clauses (a) and (b) above, the Notes are not redeemable. The Company is not prohibited, however, from acquiring the

day that is a Business Day, and no interest shall accrue on any amount that would have been otherwise payable on such redemption date if it were a Business Day for the intervening period. 

(e) Notwithstanding the foregoing, in connection with any tender offer for or other offer to purchase the Notes, including a Change of Control
Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not validly withdraw such Notes in such offer and the Company, or any third party making such an offer in lieu of the Company,
purchase all of the Notes validly tendered and not withdrawn by such Holders, all Holders will be deemed to have consented to such offer, and the Company or such third party will have the right upon not less than 10 nor more than 60 days’
notice, given not more than 30 days following such offer expiration date, to redeem the Notes that remain outstanding, in whole but not in part, following such purchase at a price equal to the price paid to each other Holder (excluding any early
tender, incentive or similar fee) in such offer, plus, to the extent not included in the offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, such redemption date. In determining whether the Holders of at least 90% of the
aggregate principal amount of the then outstanding Notes have validly tendered and not validly withdrawn Notes in a tender offer or other offer to purchase, such calculation shall include all Notes owned by an Affiliate of the Company
(notwithstanding any provision of the Indenture to the contrary).

Section 3.07 shall be made pursuant to the provisions of Section 3.01 through Section 3.06 hereof.

accompanied by consolidating or other information that explains in reasonable detail the differences between the information relating to Vistra or such other parent, on the one hand, and the information relating to the Company on a standalone basis,
on the other hand (provided, however, that the Company shall be under no obligation to deliver such consolidating or other explanatory information if the Total Assets and the Consolidated EBITDA of the Company and its consolidated
Restricted Subsidiaries do not differ from the Total Assets and the Consolidated EBITDA, respectively, of Vistra (or any other direct or indirect parent of the Company) and its consolidated Subsidiaries by more than 2.5%). 

(d) The Trustee shall have no duty to review or analyze reports delivered to it. Delivery of such reports, information and documents to the
Trustee is for informational purposes only, and the Trustee’s receipt thereof shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants under the Indenture (as to which the Trustee is entitled to rely on an Officer’s Certificate). 

Section 4.04 Compliance Certificate.

obligations under the Indenture, and further stating, as to such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in the Indenture
and is not in default in the performance or observance of any of the terms, provisions and conditions of the Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have
knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or

Section 4.05 Liens. 
 (a) The Company
will not and will not permit any Subsidiary Guarantor to, create, incur, assume or suffer to exist or become effective any mortgage, pledge or other Lien (other than (1) prior to a Release Event, Permitted Liens and (2) following a Release
Event, Permitted Post-Release Liens) upon any Principal Property to secure indebtedness for borrowed money represented by notes, bonds, debentures or other similar evidences of indebtedness, unless all payments due under the Indenture and the Notes
issued thereunder are secured on an equal and ratable basis with the Obligations so secured prior to or simultaneously with the creation of such Lien until such time as such Obligations are no longer secured by a lien. 

(b) Any Lien created for the benefit of the Holders pursuant to Section 4.05(a) shall provide by its terms that such
Lien shall be automatically and unconditionally released and discharged upon the release of the Lien that gave rise to the obligation to secure the Notes pursuant to Section 4.05(a). 

Section 4.06 Offer to Repurchase Upon a Change of Control Trigger Event. 

(a) Upon the occurrence of a Change of Control Trigger Event, each Holder will have the right to require the Company to repurchase all or any
part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s Notes pursuant to a change of control offer (the “Change of Control Offer”). In the Change of Control Offer, the Company will offer a
payment (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, on the Notes to but excluding the date of purchase, subject to the
rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control Trigger Event, the Company shall mail (or deliver electronically) a notice to each Holder
describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) that the Change of
Control Offer is being made pursuant to this Section 4.06 and that all Notes tendered will be accepted for payment; 

(2) the purchase price and the purchase date, which date will be no earlier than 10 days and no later than 60 days from the
date such notice is mailed or delivered electronically (the “Change of Control Payment Date”);

any Note not tendered will continue to accrue interest; 

  
 -50- 












 (4) that, unless the Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender the
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the
Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw their election if the Paying Agent receives,
not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, email, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered
for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral
multiple of $1,000 in excess of $2,000. 
 The Company shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a
Change of Control Trigger Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.06, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this Section 4.06 by virtue of such compliance. 

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes
properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

Paying Agent shall promptly mail or deliver electronically to each Holder properly tendered the Change of Control Payment for the Notes, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book entry) to each
Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note shall be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The
Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

 (c) Notwithstanding anything to the contrary in this Section 4.06,
the Company shall not be required to make a Change of Control Offer upon a Change of Control Trigger Event if (1) a third party makes the Change of Control Offer with respect to the Notes in the manner, at or prior to the times and otherwise in
compliance with the requirements set forth in this Section 4.06 and purchases all such Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption with respect to the Notes has been
given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control Trigger Event, with the
obligation to pay and the timing of payment conditioned upon the occurrence of a Change of Control Trigger Event, if a definitive agreement to effect a Change of Control is in place at the time the Change of Control Offer is made. 

Section 4.07 Additional Subsidiary Guarantees. 

(a) If any Eligible Subsidiary of the Company other than a Subsidiary Guarantor (i) guarantees any Indebtedness under the Credit Agreement or
(ii) if the Company has no Indebtedness outstanding under the Credit Agreement, guarantees any Additional Indebtedness, then within 30 days thereof the Company shall cause such Eligible Subsidiary to execute and deliver to the Trustee a
supplemental indenture pursuant to which such Subsidiary will guarantee payment of the Notes on the same terms and conditions as those applicable to the Subsidiary Guarantors under the Indenture and will deliver to the Trustee an Officer’s
Certificate and Opinion of Counsel that such supplemental indenture has been duly authorized, executed and delivered and constitutes a legally valid and enforceable obligation (subject to customary qualifications and exceptions). Thereafter, such
Eligible Subsidiary will be a Subsidiary Guarantor with respect to the Notes until such Eligible Subsidiary’s Subsidiary Guarantee with respect to the Notes is released in accordance with the Indenture. 

(b) The Company shall cause any such Eligible Subsidiary, substantially concurrently with the execution of a supplemental indenture pursuant to
Section 4.07(a), to pledge all of its existing and future assets constituting Collateral to secure its guarantee, and the Company shall cause all of the Capital Stock in such Eligible Subsidiary owned by the Company or any
Subsidiary Guarantor to be pledged to secure the Notes and the Subsidiary Guarantees and shall cause the Liens thereon to be valid and perfected, subject to the limitations and timing requirements set forth in this Eleventh Supplemental Indenture,
the Note Security Documents and the other Priority Lien Documents.

Trustee to maintain possession of certificates, promissory notes or other instruments actually delivered to it representing securities pledged under the Note Security Documents or (2) to the extent relating to Collateral consisting of real
property, is covered by a title insurance policy with respect to such real property and such insurer has not denied coverage; or

immediately. 
 Section 6.03 Waiver of Past Defaults. 

Holders of not less than a majority in aggregate principal amount of the Notes that are then outstanding, by notice to the Trustee may, on
behalf of the Holders, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of interest on or principal of, the Notes (including in connection with an offer to
purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee 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 the Indenture, but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon. 
 Section 6.04 Control by Majority. 

Subject to the terms of the Collateral Trust Agreement, Holders of a majority in principal amount of the Notes that are then outstanding may
direct the Trustee in its exercise of any trust or power. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or the Notes or, subject to Section 7.01 and
Section 7.02 of the Base Indenture, that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability (provided that the Trustee shall not have an 

  
 -56- 












 affirmative duty to determine whether any such direction is unduly prejudicial to any other Holder);
provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may withhold from Holders notice of any continuing Default or Event of Default if it
determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest. 

Section 6.05 Limitations on Suits. 

In case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under
the Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder of a Note may pursue any remedy with respect to the Indenture 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 Notes that are then outstanding have requested the Trustee to
pursue the remedy; 
 (3) such Holders 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; 
 (5) Holders of a majority in aggregate principal amount of the Notes that are then outstanding have
not given the Trustee a direction inconsistent with such request within such 60-day period; and 

(6) such Holders are not prohibited from taking such action pursuant to the terms of the Collateral Trust Agreement. 

Section 6.06 Collection Suit by Trustee. 

Subject to the Collateral Trust Agreement, if an Event of Default specified in Section 6.01(1) or
Section 6.01(2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and
interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding.

 Section 6.07 Priorities. 

Subject to the Collateral Trust Agreement, if the Trustee collects any money pursuant to this Article 6, it shall pay out the money in
the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.06 of the
Base Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: subject to clause Second of Section 6.07 of the Base Indenture, to Holders of Notes for amounts due and
unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 

Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.07.

 Section 6.08 Trustee May File Proofs of Claim. 

The Trustee may 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 allowed in any judicial proceedings relative to the Company, its Subsidiaries or its or their
respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the
Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian or other party making payment in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and
any other amounts due the Trustee under Section 7.06 of the Base Indenture. No provision of the Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.09 Holder Representation. 

(a) Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take
any other action (a “Noteholder Direction”) provided by any one or more Holders of the Notes (each, a “Directing Holder”) must be accompanied by a written representation from each such Holder to the Company and the
Trustee that such Holder is not (or, in the case such Holder is DTC or its nominee, that such 

  
 -58- 












 
Holder is being instructed solely by Beneficial Owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating
to a notice of Default (a “Default Direction”) shall be deemed repeated at all times until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder must,
at the time of providing a Noteholder Direction, covenant to provide the Company with such other information as the Company may reasonably request from time to time in order to verify the accuracy of such Directing Holder’s Position
Representation within five Business Days of request therefor (a “Verification Covenant”). Notwithstanding anything herein to the contrary, in any case in which the Holder is DTC or its nominee, any Position Representation or
Verification Covenant required hereunder shall be provided by the Beneficial Owner of the Notes in lieu of DTC or its nominee, and DTC shall be entitled to rely on such Position Representation and Verification Covenant in delivering its direction to
the Trustee, and such beneficial owner shall provide proof of its holdings in a manner satisfactory to the Trustee. 
 (b) If, following the
delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and
provides to the Trustee an officer’s certificate stating that the Company has initiated litigation (“Litigation”) in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in
breach of its Position Representation, and seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Event of Default shall be automatically stayed and the cure period
with respect to such Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter (a
“Final Decision”). Once such officer’s certificate has been provided to the Trustee, the Trustee shall take no further action pursuant to the related Noteholder Direction until it has actual knowledge of a Final Decision. If,
following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company provides to the Trustee an officer’s certificate stating that a Directing Holder failed to satisfy its Verification Covenant (a
“Verification Covenant Officer’s Certificate”), the cure period with respect to such Event of Default shall be automatically stayed and the cure period with respect to any Event of Default that resulted from the applicable
Noteholder Direction shall be automatically reinstituted and any remedy stayed until such time as the Company provides the Trustee with an officer’s certificate that the Verification Covenant has been satisfied (a “Covenant Satisfaction
Officer’s Certificate”); provided that the Company shall promptly deliver such officer’s certificate to the Trustee upon becoming aware that the Verification Covenant has been satisfied. Any breach of the Position
Representation (as evidenced by the delivery to the Trustee of the officer’s certificate stating that a Directing Holder failed to satisfy its Verification Covenant (a “Covenant Failure Officer’s Certificate”)) shall
result in such Holder’s participation in such Noteholder Direction being disregarded; and if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have
been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be
deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default. 

  
 -59- 












 (c) Notwithstanding anything in Section 6.09(a) or
Section 6.09(b) to the contrary, (i) any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy or similar direction shall not require compliance with the
foregoing paragraphs and (ii) a notice of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default. For the avoidance of doubt, the Trustee shall have no
duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant or verify any statements in any officer’s certificates delivered to it or otherwise make calculations with
respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no obligation to monitor or determine whether a Holder is Net Short and can rely conclusively on a
Directing Holder’s Position Representation, the officer’s certificates delivered by the Issuer and determinations made by a court of competent jurisdiction and shall have no liability for ceasing to take any action, staying any remedy or
otherwise failing to act in accordance with a Noteholder Direction during the pendency of Litigation or a Noteholder Direction after a Verification Covenant Officer’s Certificate has been provided but prior to receipt of a Covenant Satisfaction
Officer’s Certificate. The Trustee shall have no liability or responsibility to the Issuer or to any Holder or any other Person in connection with any Noteholder Direction or to determine whether or not any Holder has delivered a Position
Representation or that such Position Representation conforms with the Indenture or any other agreement.

 ARTICLE 8 
 LEGAL DEFEASANCE
AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may, at its option evidenced by a resolution of its Board of Directors set forth in an Officer’s Certificate, at any time,
elect to have either Section 8.02 or Section 8.03 hereof be applied to the Notes upon compliance with the conditions set forth below in this Article 8. 

Section 8.02 Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
Section 8.02, the Company and each of the Subsidiary 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 the Notes (including the Subsidiary Guarantees) on the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Legal Defeasance”). For this purpose,
Legal Defeasance means that the Company and the Subsidiary Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the Notes (including the Subsidiary Guarantees with respect to the Notes), which will thereafter
be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections hereof 

  
 -60- 












 referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under the
applicable Note Documents (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged
hereunder: 
 (1) the rights of Holders of such Notes to receive payments in respect of the principal of, or interest or
premium on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 

(2) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02
hereof; 
 (3) the rights, powers, trusts, duties, indemnities and immunities of the Trustee under the Indenture, and the
Company’s and the Subsidiary Guarantors’ obligations in connection therewith; and 
 (4) this Article 8.

 Subject to compliance with this Article 8, the Company 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 Company’s exercise under Section 8.01 hereof of the option applicable to this
Section 8.03, the Company and the Subsidiary Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under
Sections 4.03, 4.04, 4.05, 4.06 and 4.07 hereof with respect to the Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of the Holders (and the consequences of any thereof) in connection
with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that the Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means
that, with respect to the Notes and Subsidiary Guarantees with respect to the Notes, the Company and the Subsidiary Guarantors 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 Note Document and such omission to comply
will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of the Indenture and such Notes and Subsidiary Guarantees shall be unaffected thereby. In
addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Sections 8.04,
6.01(3), 6.01(4) and 6.01(5) hereof shall not constitute Events of Default.

 Section 8.04 Conditions to Legal or Covenant Defeasance. 

(a) In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the Notes under either
Section 8.02 or Section 8.03 hereof: 
 (1) the Company must irrevocably
deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants to pay the principal of, or
interest and premium on, such Notes that are then outstanding on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether such Notes are being defeased to maturity or to a particular
redemption date; 
 (2) in the case of Legal Defeasance, the Company has delivered to the Trustee an Opinion of Counsel
reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date,
there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the Notes that are then outstanding will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to 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 Company shall have delivered to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the Notes that are then outstanding will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income 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 or Event of Default with respect to the Notes has occurred and is continuing on the date of such deposit (other
than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit); 
 (5) such Legal
Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture) to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officer’s Certificate
stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 

  
 -62- 












 (7) the Company must deliver to the Trustee an Officer’s Certificate
and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance 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 non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to
Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the
request of the Company any money or non-callable 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(a)(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 the Company. 

Subject to applicable law, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable, shall be paid to the Company on its written request or (if then held by
the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and
all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published
once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining shall be repaid to the Company. 

  
 -63- 












 Section 8.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government
Securities in accordance with Section 8.02 or Section 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 Company’s and the Subsidiary Guarantors’ obligations under the applicable Note Documents will be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or Section 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
Section 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9 
 AMENDMENT, SUPPLEMENT
AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 

Notwithstanding Article 9 of the Base Indenture and Section 9.02 hereof, the Company, the Subsidiary Guarantors and
the Trustee may amend or supplement any Note Document without the consent of any Holder: 
 (1) to cure any ambiguity, defect
or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 

(3) to provide for the assumption of the Company’s or a Subsidiary Guarantor’s obligations to Holders in the case of
a merger or consolidation or sale of all or substantially all of the Company’s or such Subsidiary Guarantor’s assets pursuant to Article 5 of this Eleventh Supplemental Indenture (if applicable); 

(4) 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 the Indenture of any such Holder; 
 (5) to comply with requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA; 
 (6) to conform the text of the Indenture, the Subsidiary
Guarantees or the Notes to any provision of the “Description of the Notes” section of the Offering Memorandum, to the extent that such provision in the “Description of the Notes” was intended to be a verbatim or substantially
verbatim recitation of a provision of the Indenture, the Notes or the Subsidiary Guarantees, as evidenced by an Officer’s Certificate; 

  
 -64- 












 (7) to evidence and provide for the acceptance and appointment under the
Indenture of a successor Trustee pursuant to the requirements thereof; 
 (8) to provide for the issuance of Additional Notes
in accordance with the limitations set forth in the Indenture; 
 (9) to allow any Subsidiary Guarantor to execute a
supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes; 
 (10) to make, complete or confirm any
grant of Collateral permitted or required by any of the Note Documents; 
 (11) to release, discharge, terminate or
subordinate Liens on Collateral in accordance with the Note Documents; and to confirm and evidence any such release, discharge, termination or subordination; or 

(12) as provided in Section 12.03(c) and Section 12.03(e) of the Base Indenture and in the Collateral Trust
Agreement. 
 Upon the request of the Company, 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 Section 11.02 of the Base Indenture and Section 9.05 hereof the Trustee shall join with the Company and the Subsidiary
Guarantors in the execution of any amended or supplemental indenture or any other amendment of or supplement to any Note Document authorized or permitted by the terms of this Eleventh Supplemental Indenture and to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to (but may, in its sole discretion) enter into such amended or supplemental indenture or any other amendment of or supplement to any Note Document
that affects its own rights, duties, indemnities or immunities under this Eleventh Supplemental Indenture or otherwise. 
 Section 9.02 With Consent
of Holders of Notes. 
 (a) Except as provided below in this Section 9.02, the Company, the Subsidiary
Guarantors and the Trustee may amend or supplement the Note Documents (for the avoidance of doubt, other than the Base Indenture, but including, without limitation, Section 4.06 hereof) with the consent of the Holders of at
least a majority in principal aggregate amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase, or tender offer or exchange offer for, the Notes), and, subject to
Section 6.03 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on such Notes, except a payment default resulting from an
acceleration that has been rescinded) or compliance with any provision of the Note Documents may be waived with the consent of the Holders of a majority in principal aggregate amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes). Section 2.08 of the Base Indenture shall determine which Notes are considered to be “outstanding” for purposes of this
Section 9.02. 

  
 -65- 












 (b) Upon the request of the Company accompanied by a resolution of its Board of Directors
and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of the Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 11.02 of the Base
Indenture and Section 9.05 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental indenture or any amendment of or supplement to any Note Document authorized or permitted by the terms of this
Eleventh Supplemental Indenture unless such amended or supplemental indenture or any amendment of or supplement to any Note Document directly affects the Trustee’s own rights, duties, indemnities or immunities under this Eleventh Supplemental
Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture or any amendment of or supplement to any Note Document. 

(c) It is not necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any
proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 (d) After an amendment,
supplement or waiver under this Section 9.02 becomes effective, the Company shall mail or deliver electronically to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure
of the Company to mail or deliver electronically such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to
Section 6.03 hereof and Section 9.02 of the Base Indenture, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a
particular instance by the Company with any provision of the Note Documents. However, without the consent of each Holder of the Notes affected, an amendment, supplement or waiver under this Section 9.02 may not (with
respect to any such Notes held by a non-consenting Holder): 
 (1) reduce the
principal amount of the Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal
of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of any Note (other than provisions relating to the covenant described in Section 4.06 and provisions relating to the number
of days of notice to be given in the event of a redemption); 
 (3) reduce the rate of or change the time for payment of
interest on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or interest or premium on
any Note (except a rescission of acceleration of such Notes by the Holders of a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

(5) make any Note payable in currency other than that stated in the Notes; 

(6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of such Holders to
receive payments of principal of, or interest or premium on any Notes; 

  
 -66- 












 (7) waive a redemption payment with respect to any Note (other than a
payment required by the covenant described in Section 4.06 hereof); or 
 (8) make any change to
Section 9.01 hereof and this Section 9.02, as to the Notes. 
 (e) Without the consent of
the Holders of at least 66 2/3% in aggregate principal amount of the Notes then outstanding, no amendment or waiver may (A) make any change in any Note Security Documents or the provisions in the Indenture dealing with Collateral or application
of trust proceeds of the Collateral with the effect of releasing the Liens on all or substantially all of the Collateral which secure the Obligations in respect of the Notes or (B) change or alter the priority of the Liens securing the Obligations
in respect of the Notes in any material portion of the Collateral in any way adverse to the Holders of such Notes in any material respect, other than, in each case, as provided under the terms of the Note Security Documents. 

(f) Other than as expressly provided in this Section 9.02, the Base Indenture may only be amended, supplemented or
otherwise modified as and to the extent provided in the Base Indenture. 
 Section 9.03 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder. 
 Section 9.04 Notation on or Exchange of Notes. 

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

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

 Section 9.05 Trustee to Sign Amendments, etc. 

The Trustee shall sign any amended or supplemental indenture or other amendment of or supplement to any Note Document authorized pursuant to
this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities, indemnities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture or other amendment of or
supplement to any Note Document until the Board of Directors of the 

  
 -67- 












 
Company approves it. In executing any amended or supplemental indenture or other amendment of or supplement to any Note Document, the Trustee will be entitled to receive and (subject to
Section 7.01 of the Base Indenture) will be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture or other amendment of
or supplement to any Note Document is authorized or permitted by the Indenture and the Note Documents. 
 ARTICLE 10 

SUBSIDIARY GUARANTEES 
 Section 10.01
Guarantee. 
 (a) Subject to this Article 10, each of the Subsidiary Guarantors hereby, jointly and severally, irrevocably and
unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the
Company hereunder or thereunder, that: 
 (1) the principal of, premium, if any, and interest on the Notes shall be promptly
paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company 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 

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be
promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors will be
jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. The obligations of each Subsidiary Guarantor in respect of its guarantee are secured
by the Collateral on a senior secured basis as provided in the Note Security Documents. 
 (b) The Subsidiary Guarantors hereby agree that
their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to
any provisions hereof or thereof, the recovery of any judgment against the Company, 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 Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands
whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and the Indenture. 

  
 -68- 












 (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company, the Subsidiary Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary
Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (d) Each Subsidiary Guarantor agrees that
it will 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 Subsidiary Guarantor further agrees that, as between the
Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary
Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) 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) will forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Subsidiary Guarantee. The Subsidiary Guarantors will have the right to seek
contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee. 

Section 10.02 Limitation on Subsidiary Guarantor Liability. 

Each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the
Subsidiary Guarantee of such Subsidiary 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 Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor will be limited to the
maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Subsidiary 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 Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article 10, result in the obligations of such Subsidiary Guarantor under its
Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 
 Section 10.03 Subsidiary Guarantors May Consolidate, etc., on Certain
Terms. 
 (a) Except as otherwise provided in Section 10.04 hereof, no Subsidiary Guarantor may sell or
otherwise dispose, in one or a series of related transactions, of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person, other than the
Company or another Subsidiary Guarantor, unless immediately after giving effect to that transaction, no Default or Event of Default exists. 

  
 -69- 












 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and
conditions of the Indenture to be performed by the Subsidiary Guarantor, such successor Person shall succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such
successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the
Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under the Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such
Subsidiary Guarantees had been issued on the Issue Date. 
 Except as set forth in Article 4 and Article 5 hereof, nothing
contained in the Indenture or in any of the Notes will prevent any consolidation or merger of a Subsidiary Guarantor with or into the Company or another Subsidiary Guarantor, or will prevent any sale or conveyance of the property of a Subsidiary
Guarantor as an entirety or substantially as an entirety to the Company or another Subsidiary Guarantor. 
 Section 10.04 Releases. 

(a) The Subsidiary Guarantee of a Subsidiary Guarantor will be released automatically: 

(1) upon the release, discharge or termination of such Subsidiary Guarantor’s guarantee of all obligations of the Company
under the Credit Agreement; 
 (2) if such Subsidiary Guarantor has become a guarantor of any Additional Indebtedness, upon
the release, discharge or termination of such Subsidiary Guarantor’s guarantee of all obligations of the Company under such Additional Indebtedness; or 

(3) upon defeasance or satisfaction and discharge of the Notes as provided in Article 8 and Article 11 hereof.

 (b) Upon delivery by the Company to the Trustee of an Officer’s Certificate to the effect that the action or event giving rise to a
release has occurred as specified above, the Trustee shall, upon receipt by it of the documents described in Section 11.02 of the Base Indenture, execute any documents reasonably requested by the Company or the Trustee in
order to evidence the release of any Subsidiary Guarantor from its obligations under its Subsidiary Guarantee. 
 (c) Any Subsidiary
Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 10.04 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the
other obligations of any Subsidiary Guarantor under the Indenture as provided in this Article 10.

 ARTICLE 11 

SATISFACTION AND DISCHARGE 
 Section 11.01
Satisfaction and Discharge. 
 The Indenture will be discharged and will cease to be of further effect as to all Notes issued
hereunder, when: 
 (1) either: 

(A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 

(B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the
distribution of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Subsidiary Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for
the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities or a combination of cash in U.S. dollars and non-callable Government Securities, in
such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to
the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of the
deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the
Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound; 
 (3) the
Company or any Subsidiary Guarantor has paid or caused to be paid all sums payable by it with respect to all Notes under this Eleventh Supplemental Indenture; and 

(4) the Company has delivered irrevocable written instructions to the Trustee under the Indenture to apply the deposited money
toward the payment of the Notes at maturity or the redemption date, as the case may be. 
 In addition, the Company 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. 

  
 -71- 












 Notwithstanding the satisfaction and discharge of this Eleventh Supplemental Indenture as to
Notes issued hereunder, if money has been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 11.01, the provisions of Section 11.02 and Section
8.06 hereof will survive. 
 Section 11.02 Application of Trust Money. 

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

 Capitalized terms used herein have the meanings assigned to them in the Supplemental Indenture referred to below unless
otherwise indicated. 
 1. Interest. Vistra Operations Company LLC, a Delaware limited liability company (the
“Company”), promises to pay interest on the principal amount of this Note at 4.875% per annum from May 13, 2022 until maturity. The Company shall pay interest semi-annually in arrears on May 13 and November 13 of each
year, or if any such day is not a Business Day, on the next succeeding Business Day (and without any additional interest or other payment in respect of any delay) (each, an “Interest Payment Date”), with the same force and effect as
if made on such date. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further, that the
first Interest Payment Date shall be November 13, 2022. Interest will be computed on the basis of a 360-day year of twelve 30-day months, and with respect to any
period less than a full calendar month, on the basis of the actual number of days elapsed during the period. 
 2. Method of Payment.
The Company shall pay interest on the Notes to the Persons who are registered Holders of Notes on April 28 and October 29 (whether or not a Business Day) immediately preceding the Interest Payment Date, except that interest payable at
maturity will be paid to the person to whom principal is paid. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose, or, at the option of the Company, payment of
interest and 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
and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company 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, Wilmington
Trust, National Association, the Trustee under the Indenture, will act as Paying Agent and the Registrar. The Company may change any Paying Agent or the Registrar without prior notice to any Holder. The Company or any of its Subsidiaries may act in
any such capacity. 

  
 -A-3- 












 4. Indenture. The Company issued the Notes as one of a duly authenticated series of
securities of the Company issued and to be issued in one or more series under an Indenture dated as of June 11, 2019 (the “Base Indenture”), between the Company and the Trustee, as amended by the Eleventh Supplemental Indenture
dated as of May 13, 2022 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Subsidiary Guarantors and the Trustee, and Holders are referred to the
Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Base Indenture, the provisions of this Note shall govern and be controlling, and to the extent any provision of this Note
conflicts with the express provisions of the Supplemental Indenture, the provisions of the Supplemental Indenture shall govern and be controlling. The Company shall be entitled to issue Additional Notes pursuant to
Section 2.07 of the Supplemental Indenture. 
 5. Optional Redemption. 

(a) At any time prior to May 13, 2023, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than
10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to but excluding the redemption date, subject to
the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. 
 (b) At any time on or
after May 13, 2023 the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed
plus accrued and unpaid interest, if any, to but excluding the redemption date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. 

(c) Except pursuant to clauses (a) and (b) above, the Notes are not redeemable. The Company and its subsidiaries are not prohibited,
however, from acquiring the Notes in market transactions by means other than a redemption, whether pursuant to a tender offer or otherwise. 

(d) If a redemption date is not a Business Day, payment may be made on the next succeeding day that is a Business Day, and no interest shall
accrue on any amount that would have been otherwise payable on such redemption date if it were a Business Day for the intervening period. 

(e) Notwithstanding the foregoing, in connection with any tender offer for or other offer to purchase the Notes, including a Change of Control
Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not validly withdraw such Notes in such offer and the Company, or any third party making such an offer in lieu of the Company,
purchase all of the Notes validly tendered and not withdrawn by such Holders, all Holders will be deemed to have consented to such offer, and the Company or such third party will have the right upon not less than 10 nor more than 60 days’
notice, given not more than 30 days following such offer expiration date, to redeem the Notes that remain outstanding, in whole but not in part, following such purchase at a price equal to the price paid to each other Holder (excluding any early
tender, incentive or similar fee) in such offer, plus, to the 

  
 -A-4- 












 extent not included in the offer payment, accrued and unpaid interest, if any, thereon, to, but excluding,
such redemption date. In determining whether the Holders of at least 90% of the aggregate principal amount of the then outstanding Notes have validly tendered and not validly withdrawn Notes in a tender offer or other offer to purchase, the
denominator in such calculation shall include all Notes owned by an Affiliate of the Company (notwithstanding any provision of the Indenture to the contrary). 

6. Offer to Repurchase Upon a Change of Control Trigger Event. Upon the occurrence of a Change of Control Trigger Event, each Holder
shall have the right to require the Company to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of each Holder’s Notes at a
purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest on the Notes, if any, to but excluding the date of purchase, subject to the rights of Holders of Notes on the relevant record
date to receive interest due on the relevant interest payment date specified in the notice (the “Change of Control Payment”). Within 30 days following any Change of Control Trigger Event, the Company shall mail (or deliver
electronically) a notice to each Holder describing the transaction or transactions that constitute the Change of Control as required by the Indenture. 

7. Notice of Redemption. Notice of redemption will be furnished at least 10 days but not more than 60 days before the redemption date to
each Holder whose Notes are to be redeemed. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Notes or portions thereof called for redemption. 
 8. Denominations, Transfer, Exchange. The Notes are
in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. A Holder may transfer or exchange Notes in accordance with the provisions of the Supplemental Indenture. The Registrar and
the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Notes. There will be no service charge for any transfer or exchange of the Notes, but Holders will be
required to pay all taxes due on transfer. The Company is not required to transfer or exchange any Note selected for redemption or to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed. The registered
Holder will be treated as the owner of the Note for all purposes. 
 9. Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes. 
 10. Amendment, Supplement and Waiver. The Base Indenture may be amended as provided therein.
The Note Documents (for the avoidance of doubt, other than the Base Indenture) may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a 

  
 -A-5- 












 purchase of, or tender offer or exchange offer for, the Notes). Without the consent of the Holders of at
least 66 2/3% in aggregate principal amount of the then outstanding Notes, no amendment or waiver may (i) make any change in any Note Security Documents or the provisions in the Indenture dealing with Collateral or application of trust proceeds
of the Collateral with the effect of releasing the Liens on all or substantially all of the Collateral which secure the Obligations in respect of the Notes or (ii) change or alter the priority of the Liens securing the Obligations in respect of
the Notes in any material portion of the Collateral in any way adverse to the Holders of the Notes in any material respect, other than, in each case, as provided under the terms of the Note Security Documents. Without the consent of any Holder of a
Note, the Note Documents may be amended or supplemented (i) to cure any ambiguity, defect or inconsistency, (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes, (iii) to provide for the assumption
of the Company’s or a Subsidiary Guarantor’s obligations to Holders of the Notes in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Subsidiary Guarantor’s assets pursuant to
Article 5 of the Supplemental Indenture, (iv) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under the S Indenture, (v) to comply
with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act of 1939, as amended, (vi) to conform the text of the Indenture, the Notes, or the Subsidiary Guarantees to any
provision of the “Description of the Notes” in the Offering Memorandum to the extent that such provision in the “Description of the Notes” was intended to be a verbatim or substantially verbatim recitation of a provision of the
Indenture, the Notes or the Subsidiary Guarantees as evidenced by an Officer’s Certificate of the Company, (vii) to evidence and provide for the acceptance and appointment under the Indenture of a successor Trustee pursuant to the
requirements thereof, (viii) to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, (ix) to allow any Subsidiary Guarantor to execute a supplemental indenture and/or Subsidiary Guarantee
with respect to the Notes, (x) to make, complete or confirm any grant of Collateral permitted or required by any of the Note Documents, (xi) to release, discharge, terminate or subordinate Liens on Collateral in accordance with the Note
Documents; and to confirm and evidence any such release, discharge, termination or subordination or (xii) with respect to the Note Documents, as provided in the Collateral Trust Agreement.

any document evidencing any indebtedness for borrowed money by the Company or any Subsidiary Guarantor, whether such indebtedness now exists or is created after the Issue Date, if that default: (A) is caused by a failure to pay principal when
due at final (and not any interim) maturity on or prior to the expiration of any grace period provided in such indebtedness (a “Payment Default”); or (B) results in the acceleration of such indebtedness prior to its express
maturity (without such acceleration having been rescinded, annulled or otherwise cured), and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated (without such acceleration 

  
 -A-6- 












 having been rescinded, annulled or otherwise cured), aggregates $300.0 million or more; provided
that this clause (4) shall not apply to (i) secured indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such indebtedness and (ii) any indebtedness that is required to be
converted into Qualifying Equity Interests upon the occurrence of certain designated events so long as no payments in cash or otherwise are required to be made in accordance with such conversion); (5) except as permitted by the Indenture, any
Subsidiary Guarantee of any Subsidiary Guarantor (or any group of Subsidiary Guarantors) that constitutes a Significant Subsidiary shall be held in any final and non-appealable judicial proceeding to be
unenforceable or invalid or shall cease for any reason (other than in accordance with its terms) to be in full force and effect or any Subsidiary Guarantor (or any group of Subsidiary Guarantors) that constitutes a Significant Subsidiary, or any
Person acting on behalf of any Subsidiary Guarantor (or any group of Subsidiary Guarantors) that constitutes a Significant Subsidiary, shall deny or disaffirm in writing its or their obligations under its or their Subsidiary Guarantees; (6)(a) a
court of competent jurisdiction (i) enters an order or decree under any Bankruptcy Law that is for relief against the Company, any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that, taken together,
would constitute a Significant Subsidiary in an involuntary case; (ii) appoints a custodian for all or substantially all of the property of the Company, any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary
Guarantors that, taken together, would constitute a Significant Subsidiary; or (iii) orders the liquidation of the Company, any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that, taken together,
would constitute a Significant Subsidiary and, in each of clauses (i), (ii) or (iii), the order, appointment or decree remains unstayed and in effect for at least 60 consecutive days; or (b) the Company, any Subsidiary Guarantor that is a
Significant Subsidiary or any group of Subsidiary Guarantors that, taken together, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law (i) commences a voluntary case; (ii) consents to the entry of
an order for relief against it in an involuntary case; (iii) consents to the appointment of a custodian of it or for all or substantially all of its property; or (iv) makes a general assignment for the benefit of its creditors; and
(7) other than by reason of the satisfaction in full of all Obligations under the Supplemental Indenture and discharge of the Indenture with respect to the Notes or the release of such Collateral with respect to the Notes in accordance with the
terms of the Indenture and the Note Security Documents: (A) in the case of any security interest with respect to Collateral having a fair market value in excess of 5% of Total Assets, individually or in the aggregate, such security interest
under the Note Security Documents shall, at any time, cease to be a valid and perfected security interest or shall be declared invalid or unenforceable and any such default continues for 30 days after notice of such default shall have been given to
the Company by the Trustee or the Holders of at least 30% in principal amount of the Notes, except to the extent that any such default (1) results from the failure of the Collateral Trustee to maintain possession of certificates, promissory
notes or other instruments actually delivered to it representing securities pledged under the Note Security Documents or (2) to the extent relating to Collateral consisting of real property, is covered by a title insurance policy with respect
to such real property and such insurer has not denied coverage; or (B) the Company or any Subsidiary Guarantor that is a Significant Subsidiary (or any group of Subsidiary Guarantors that, taken together, would constitute a Significant
Subsidiary) shall assert, in any pleading in any court of competent jurisdiction, that any security interest under any Note Security Document is invalid or unenforceable. 

  
 -A-7- 












 12. Security and Collateral. The Notes will be entitled to the benefits of certain
Collateral pledged for the benefit of the Holders pursuant to the terms of the Note Documents. Reference is hereby made to the Note Documents for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the
Company, the Subsidiary Guarantors, the Collateral Trustee, the Trustee and the Holders. The Company agrees, and each Holder by accepting a Note agrees, to the provisions contained in the Note Documents. 

13. Trustee Dealings with Company. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may
otherwise deal with the Company or any Subsidiary Guarantor or any Affiliate of the Company or any Subsidiary Guarantor 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 (if the Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also
subject to Section 7.09 of the Base Indenture. 
 14. No Recourse Against Others. No director, officer, employee, incorporator or
stockholder of the Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or the Subsidiary Guarantors under the Notes, the Indenture, the Subsidiary Guarantees or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive
liabilities under the federal securities laws. 
 15. Authentication. This Note will not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent. 
 16. Abbreviations. Customary abbreviations may be used in the name of a Holder
or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

17. CUSIP Numbers/ISINs. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP numbers/ISINs to be printed on the Notes and the Trustee may use CUSIP numbers/ISINs in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the
Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

 Capitalized terms used herein have the meanings assigned to them in the Supplemental Indenture referred to below unless otherwise
indicated. 
 1. Interest. Vistra Operations Company LLC, a Delaware limited liability company (the “Company”),
promises to pay interest on the principal amount of this Note at 5.125% per annum from May 13, 2022 until maturity. The Company shall pay interest semi-annually in arrears on May 13 and November 13 of each year, or if any such day is
not a Business Day, on the next succeeding Business Day (and without any additional interest or other payment in respect of any delay) (each, an “Interest Payment Date”), with the same force and effect as if made on such date.
Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this
Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further, that the first Interest Payment
Date shall be November 13, 2022. Interest will be computed on the basis of a 360-day year of twelve 30-day months, and with respect to any period less than a full
calendar month, on the basis of the actual number of days elapsed during the period. 
 2. Method of Payment. The Company shall pay
interest on the Notes to the Persons who are registered Holders of Notes on April 28 and October 29 (whether or not a Business Day) immediately preceding the Interest Payment Date, except that interest payable at maturity will be paid to
the person to whom principal is paid. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose, or, at the option of the Company, payment of interest and 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 and premium, if any, on,
all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company 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, Wilmington Trust, National
Association, the Trustee under the Indenture, will act as Paying Agent and the Registrar. The Company may change any Paying Agent or the Registrar without prior notice to any Holder. The Company or any of its Subsidiaries may act in any such
capacity. 

  
 -B-3- 












 4. Indenture. The Company issued the Notes as one of a duly authenticated series of
securities of the Company issued and to be issued in one or more series under an Indenture dated as of June 11, 2019 (the “Base Indenture”), between the Company and the Trustee, as amended by the Eleventh Supplemental Indenture
dated as of May 13, 2022 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Subsidiary Guarantors and the Trustee, and Holders are referred to the
Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Base Indenture, the provisions of this Note shall govern and be controlling, and to the extent any provision of this Note
conflicts with the express provisions of the Supplemental Indenture, the provisions of the Supplemental Indenture shall govern and be controlling. The Company shall be entitled to issue Additional Notes pursuant to
Section 2.07 of the Supplemental Indenture. 
 5. Optional Redemption. 

(a) At any time prior to May 13, 2025, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than
10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to but excluding the redemption date, subject to
the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. 
 (b) Except pursuant to
clauses (a) above, the Notes are not redeemable. The Company and its subsidiaries are not prohibited, however, from acquiring the Notes in market transactions by means other than a redemption, whether pursuant to a tender offer or otherwise.

 (c) If a redemption date is not a Business Day, payment may be made on the next succeeding day that is a Business Day, and no interest
shall accrue on any amount that would have been otherwise payable on such redemption date if it were a Business Day for the intervening period. 

(d) Notwithstanding the foregoing, in connection with any tender offer for or other offer to purchase the Notes, including a Change of Control
Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not validly withdraw such Notes in such offer and the Company, or any third party making such an offer in lieu of the Company,
purchase all of the Notes validly tendered and not withdrawn by such Holders, all Holders will be deemed to have consented to such offer, and the Company or such third party will have the right upon not less than 10 nor more than 60 days’
notice, given not more than 30 days following such offer expiration date, to redeem the Notes that remain outstanding, in whole but not in part, following such purchase at a price equal to the price paid to each other Holder (excluding any early
tender, incentive or similar fee) in such offer, plus, to the extent not included in the offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, such redemption date. In determining whether the Holders of at least 90% of the
aggregate principal amount of the then outstanding Notes have validly tendered and not validly withdrawn Notes in a tender offer or other offer to purchase, the denominator in such calculation shall include all Notes owned by an Affiliate of the
Company (notwithstanding any provision of the Indenture to the contrary). 

  
 -B-4- 












 6. Offer to Repurchase Upon a Change of Control Trigger Event. Upon the occurrence of
a Change of Control Trigger Event, each Holder shall have the right to require the Company to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of
$2,000) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest on the Notes, if any, to but excluding the date of purchase, subject to the rights of
Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date specified in the notice (the “Change of Control Payment”). Within 30 days following any Change of Control Trigger Event, the
Company shall mail (or deliver electronically) a notice to each Holder describing the transaction or transactions that constitute the Change of Control as required by the Indenture. 

7. Notice of Redemption. Notice of redemption will be furnished at least 10 days but not more than 60 days before the redemption date to
each Holder whose Notes are to be redeemed. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Notes or portions thereof called for redemption. 
 8. Denominations, Transfer, Exchange. The Notes are
in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. A Holder may transfer or exchange Notes in accordance with the provisions of the Supplemental Indenture. The Registrar and
the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Notes. There will be no service charge for any transfer or exchange of the Notes, but Holders will be
required to pay all taxes due on transfer. The Company is not required to transfer or exchange any Note selected for redemption or to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed. The registered
Holder will be treated as the owner of the Note for all purposes. 
 9. Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes. 
 10. Amendment, Supplement and Waiver. The Base Indenture may be amended as provided therein.
The Note Documents (for the avoidance of doubt, other than the Base Indenture) may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Without the consent of the Holders of at least 66 2/3%
in aggregate principal amount of the then outstanding Notes, no amendment or waiver may (i) make any change in any Note Security Documents or the provisions in the Indenture dealing with Collateral or application of trust proceeds of the
Collateral with the effect of releasing the Liens on all or substantially all of the Collateral which secure the Obligations in respect of the Notes or (ii) change or alter the priority of the Liens securing the Obligations in respect of the
Notes in any material portion of the Collateral in any 

  
 -B-5- 












 way adverse to the Holders of the Notes in any material respect, other than, in each case, as provided under
the terms of the Note Security Documents. Without the consent of any Holder of a Note, the Note Documents may be amended or supplemented (i) to cure any ambiguity, defect or inconsistency, (ii) to provide for uncertificated Notes in
addition to or in place of certificated Notes, (iii) to provide for the assumption of the Company’s or a Subsidiary Guarantor’s obligations to Holders of the Notes in the case of a merger or consolidation or sale of all or
substantially all of the Company’s or such Subsidiary Guarantor’s assets pursuant to Article 5 of the Supplemental Indenture, (iv) to make any change that would provide any additional rights or benefits to the Holders of Notes
or that does not adversely affect the legal rights under the S Indenture, (v) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act of 1939, as amended,
(vi) to conform the text of the Indenture, the Notes, or the Subsidiary Guarantees to any provision of the “Description of the Notes” in the Offering Memorandum to the extent that such provision in the “Description of the
Notes” was intended to be a verbatim or substantially verbatim recitation of a provision of the Indenture, the Notes or the Subsidiary Guarantees as evidenced by an Officer’s Certificate of the Company, (vii) to evidence and provide
for the acceptance and appointment under the Indenture of a successor Trustee pursuant to the requirements thereof, (viii) to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, (ix) to
allow any Subsidiary Guarantor to execute a supplemental indenture and/or Subsidiary Guarantee with respect to the Notes, (x) to make, complete or confirm any grant of Collateral permitted or required by any of the Note Documents, (xi) to
release, discharge, terminate or subordinate Liens on Collateral in accordance with the Note Documents; and to confirm and evidence any such release, discharge, termination or subordination or (xii) with respect to the Note Documents, as
provided in the Collateral Trust Agreement. 
 11. Defaults and Remedies. Events of Default include: (1) default for 30 days in
the payment when due of interest on the Notes; (2) default in payment when due of the principal of, or premium, if any, on the Notes; (3) failure by the Company or a Subsidiary Guarantor to comply with any covenant in the Indenture (other

Notes then outstanding; (4) default under any document evidencing any indebtedness for borrowed money by the Company or any Subsidiary Guarantor, whether such indebtedness now exists or is created after the Issue Date, if that default:
(A) is caused by a failure to pay principal when due at final (and not any interim) maturity on or prior to the expiration of any grace period provided in such indebtedness (a “Payment Default”); or (B) results in the

such default continues for 30 days after notice of such default shall have been given to the Company by the Trustee or the Holders of at least 30% in principal amount of the Notes, except to the extent that any such default (1) results from the
failure of the Collateral Trustee to maintain possession of certificates, promissory notes or other instruments actually delivered to it representing securities pledged under the Note Security Documents or (2) to the extent relating to

benefit of the Holders pursuant to the terms of the Note Documents. Reference is hereby made to the Note Documents for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Company, the Subsidiary
Guarantors, the Collateral Trustee, the Trustee and the Holders. The Company agrees, and each Holder by accepting a Note agrees, to the provisions contained in the Note Documents. 

  
 -B-7- 












 13. Trustee Dealings with Company. The Trustee in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Subsidiary Guarantor or any Affiliate of the Company or any Subsidiary Guarantor 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 (if the Indenture has been qualified under the TIA) or resign. Any Agent may do the
same with like rights and duties. The Trustee is also subject to Section 7.09 of the Base Indenture. 
 14. No Recourse Against
Others. No director, officer, employee, incorporator or stockholder of the Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or the Subsidiary Guarantors under the Notes, the Indenture, the
Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws. 
 15. Authentication.
This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
 16.

common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers/ISINs to be printed on the Notes and the Trustee may use CUSIP numbers/ISINs in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
