increased to provide for issuances of additional Securities of such Series, unless otherwise provided in such Supplemental Indenture. 
 (d)
Global Securities will be in the form specified in the Supplemental Indenture pursuant to which such Series of Securities is created. Each Global Security shall represent such of the outstanding Securities of a Series as will be specified therein
and each shall provide that it represents the aggregate principal amount of outstanding Securities of such Series from time to time as reflected in the records of the Trustee and that the aggregate principal amount of outstanding Securities of such
Series represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. The Trustee’s records shall be noted to reflect the amount of any increase or decrease in the aggregate principal
amount of outstanding Securities of such Series represented thereby, in accordance with instructions given by the Holder thereof. 
 Section 2.02
Execution and Authentication. 
 One Officer must sign the Securities for the Company by manual, facsimile or .pdf signature. 

If an Officer whose signature is on a Security no longer holds that office at the time a Security is authenticated, the Security will
nevertheless be valid. 
 A Security will not be valid until authenticated by the manual signature of the Trustee. The signature will be
conclusive evidence that the Security has been authenticated under this Indenture. A Security shall be dated the date of its authentication. 

  
 -22- 

 The Trustee shall, upon receipt of a Company Order, authenticate Securities for original
issue under this Indenture. The aggregate principal amount of Securities outstanding at any time may not exceed the aggregate principal amount of Securities authorized for issuance by the Company pursuant to one or more Company Orders, except as
provided in Section 2.07 hereof. 
 The Trustee shall not be required to authenticate such Securities if the issue
thereof will adversely affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. Notwithstanding the generality of the foregoing,
the Trustee will not be required to authenticate Securities denominated in any currency other than U.S. dollars if the Trustee reasonably believes that it would be unable to perform its duties with respect to the such Securities. 

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders, the Company or an
Affiliate of the Company. 
 Section 2.03 Registrar and Paying Agent. 

(a) The Company will maintain a Registrar and a Paying Agent with respect to each Series of Securities issued pursuant to this Indenture. The
Registrar will keep a register of the Holders and the Securities and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional Paying Agents and may change any Paying Agent or Registrar without
notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. The Company or any of the Company’s Subsidiaries may act as Paying Agent or Registrar. 

(b) The Company initially appoints DTC to act as Depository with respect to each Series unless another Depository is appointed prior to the
time Securities of that Series are first issued. 
 (c) The Company initially appoints the Trustee to act as the Registrar and Paying Agent
with respect to each Series unless another Registrar and Paying Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued. 

Section 2.04 Paying Agent to Hold Money in Trust. 

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent (i) will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on such Securities and (ii) will notify the Trustee in writing of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary of the Company) will have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it will segregate

  
 -23- 

 
and hold in a separate trust fund for the benefit of the Holders of any Series of Securities all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to
the Company, the Trustee will serve as Paying Agent for each Series of Securities. 
 Section 2.05 Holder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
all Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of the Holders. 
 Section 2.06 Transfer and Exchange. 

(a) Transfer and Exchange of Global Securities and Definitive Securities. A Global Security may not be transferred as a whole except by
the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or to another nominee of the Depository, or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.
The Company shall exchange Global Securities for Definitive Securities of the same Series if at any time: 
 (1) the Company
delivers to the Trustee notice from the Depository that it is unwilling or unable to continue to act as Depository or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depository is not
appointed by the Company within 90 days after the date of such notice from the Depository; 
 (2) the Company in its
sole discretion determines that the Global Securities of a given Series (in whole but not in part) should be exchanged for Definitive Securities of the same Series and delivers an Officer’s Certificate to such effect to the Trustee; or 

(3) upon the written request of a Holder if a Default or Event of Default shall have occurred and be continuing with respect to
the Securities of such Series. 
 Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Securities
shall be issued in such names and in any approved denominations as the Depository shall instruct the Trustee. Global Securities also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every
Security authenticated and delivered in exchange for, or in lieu of, a Global Security or any portion thereof, pursuant to this Section 2.06 or Sections 2.07 or 2.10 hereof, shall be authenticated and
delivered in the form of, and shall be, a Global Security. Definitive Securities and beneficial interests in a Global Security may each be transferred and exchanged as provided in the Supplemental Indenture pursuant to which such applicable Series
of Securities is created. 

  
 -24- 

 (b) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global
Securities and Definitive Securities upon receipt of a Company Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(2) No service charge shall be made to a Holder of a Global Security or to a Holder of a Definitive Security for any
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchange or transfer pursuant to Sections 2.10, 3.06 and 9.04 hereof). 

(3) The Registrar shall not be required to register the transfer of or exchange any Security selected for redemption in whole
or in part, except the unredeemed portion of any Security being redeemed in part. 
 (4) All Global Securities and Definitive
Securities issued upon any registration of transfer or exchange of Global Securities or Definitive Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Securities or Definitive Securities surrendered upon such registration of transfer or exchange. 
 (5) Neither the
Registrar nor the Company shall be required: 
 (A) to issue, to register the transfer of or to exchange any Securities
during a period beginning at the opening of business 15 days before the day of any selection of Securities for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 

(B) to register the transfer of or to exchange any Security selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part; or 
 (C) to register the transfer of or to exchange a Security between a
record date and the next succeeding interest payment date. 
 (6) Prior to due presentment for the registration of a transfer
of any Security, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such
Securities and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 

(7) The Trustee shall authenticate Global Securities and Definitive Securities in accordance with the provisions of
Section 2.02 hereof. 

  
 -25- 

 (8) All orders, certifications, certificates and Opinions of Counsel
required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 

(9) Notwithstanding anything herein to the contrary, neither the Trustee nor the Registrar shall be responsible for
ascertaining whether any transfer or exchange complies with the registration provisions of or exemptions from the Securities Act or applicable state securities laws. 

(c) Legends. Securities of a Series will bear the legends provided for in the Supplemental Indenture pursuant to which such Series of
Securities is created. 
 Section 2.07 Replacement Securities. 

(a) If any mutilated Security is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Security, the Company will issue and the Trustee, upon receipt of a Company Order, will authenticate a replacement Security of the same Series if the Trustee’s requirements are met. An indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Company may
charge for its expenses in replacing a Security. 
 (b) Every replacement Security is an additional obligation of the Company and will be
entitled to all of the benefits of this Indenture equally and proportionately with all other Securities of such Series duly issued hereunder. 

Section 2.08 Outstanding Securities. 

(a) The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof or any applicable Supplemental Indenture, and those described in this
Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security;
however, Securities held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 9.02(a) hereof. 

(b) If a Security is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee
receives proof satisfactory to it that the replaced Security is held by a protected purchaser. 
 (c) If the principal amount of any
Security is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

(d) If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate of any thereof) holds, on a redemption date or
maturity date, money sufficient to pay Securities payable on that date, then on and after that date such Securities will be deemed to be no longer outstanding and will cease to accrue interest. 

  
 -26- 

 Section 2.09 Treasury Securities. 

In determining whether the Holders of the required principal amount of Securities of a given Series have concurred in any direction, waiver or
consent, Securities of such Series owned by the Company or any Subsidiary Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary Guarantor, will
be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows
are so owned will be so disregarded. 
 Section 2.10 Temporary Securities. 

(a) Until certificates representing Securities are ready for delivery, the Company may prepare and the Trustee, upon receipt of a Company
Order, will authenticate temporary Securities. Temporary Securities will be substantially in the form of certificated Securities but may have variations that the Company considers appropriate for temporary Securities and as may be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate Definitive Securities of the same Series in exchange for temporary Securities. 

(b) Holders of temporary Securities will be entitled to all of the benefits of this Indenture as the definitive Securities of the same Series.

The Company may, with respect to any Series of Securities, reserve the right to redeem and pay the Series of Securities or may covenant to
redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in such Securities. If a Series of Securities is redeemable and the Company elects or is obligated to
redeem such Series of Securities pursuant to the provisions of such Securities, it must furnish to the Trustee, at least 10 days but not more than 60 days before a redemption date, an Officer’s Certificate setting forth:

exchange requirements. 
 In the event of partial redemption by lot, the particular Securities of the Series to be redeemed shall be
selected, unless otherwise provided herein, not less than 10 nor more than 60 days prior to the redemption by the Trustee from the outstanding Securities of such Series not previously called for redemption. 

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected
for partial redemption, the principal amount thereof to be redeemed. Securities and portions of Securities selected shall be in minimum amounts of $2,000 or whole multiples of $1,000 in excess of $2,000; except that if all of the Securities of a
Holder of any Series are to be redeemed, the entire outstanding amount of Securities of such Series held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture
that apply to a Series of Securities called for redemption also apply to portions of Securities called for redemption. 
 No Securities of a
Series of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first-class mail or delivered electronically at least 10 but not more than 60 days before the redemption date to each Holder to be redeemed at its

and discharge of this Indenture. 

  
 -28- 

 If any Security of a Series is to be redeemed in part only, the notice of redemption that
relates to that Security shall state the portion of the principal amount of that Security that is to be redeemed. In the case of certificated Securities, a new Security of such Series in principal amount equal to the unredeemed portion of the
original Security shall be issued in the name of the Holder upon cancellation of the original Security. Securities of a Series called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Securities of a Series or portions of them called for redemption unless the Company defaults in making the applicable redemption payment. 

Section 3.03 Notice of Redemption. 

At least 10 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first-class
mail or delivered electronically, a notice of redemption to each Holder whose Securities are to be redeemed at its registered address, except that redemption notices may be mailed or delivered electronically more than 60 days prior to a
redemption date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of this Indenture pursuant to Article 8 or Article 10 hereof. 

The notice will identify the Securities of the Series to be redeemed and will state: 

(1) the redemption date; 

(2) the redemption price; 

(3) if any Security of such Series is being redeemed in part, the portion of the principal amount of such Security to be
redeemed and that, after the redemption date upon surrender of such Security, in the case of certificated Securities, a new Security or Securities in principal amount equal to the unredeemed portion will be issued in the name of the Holder upon
cancellation of the original Security; 
 (4) the name and address of the Paying Agent; 

(5) that Securities of such Series called for redemption must be surrendered to the Paying Agent to collect the redemption
price; 
 (6) that, unless the Company defaults in making such redemption payment, interest on Securities of such Series
called for redemption ceases to accrue on and after the redemption date; 
 (7) the applicable section of this Indenture
and/or the Supplemental Indenture for the applicable Series pursuant to which the Securities of such Series called for redemption are being redeemed; 

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or
printed on the Securities; and 

  
 -29- 

 (9) if such redemption is subject to the satisfaction of one of more
conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or 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.

 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense;
provided, however, that the Company has delivered to the Trustee, at least 10 days prior to the redemption date (or such shorter period as the Trustee in its sole discretion may allow), an Officer’s Certificate requesting
that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Any redemption and notice thereof may, in the Company’s discretion, be subject to the satisfaction of one or more conditions precedent.

 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed or delivered electronically in accordance with Section 3.03 hereof, Securities of
the Series called for redemption become, subject to any conditions precedent set forth in the notice of redemption, irrevocably due and payable on the redemption date at the redemption price. 

Section 3.05 Deposit of Redemption Price. 

One Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of, accrued interest to but excluding the redemption date, and premium, if any, on all Securities to be redeemed on that date. Promptly after the Company’s written request, the Trustee or the Paying Agent shall promptly return
to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, accrued interest, and premium, if any, on, all Securities to be redeemed. 

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest will cease to accrue on the
Securities or the portions of Securities called for redemption. 
 If a Security is redeemed on or after an interest record date but on or
prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Security was registered at the close of business on such record date. If any Security called for redemption is not so
paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 4.01 hereof. 

  
 -30- 

 Section 3.06 Securities Redeemed in Part.

(b) The Company may also from time to time designate one or more other offices or agencies where the Securities of a Series may be presented

(2) all current reports of the Company that would be required to be filed with the SEC on

Subsidiaries by more than 2.5%). 
 (d) Delivery of such reports, information and documents to the Trustee is for informational purposes

terms of defaults and remedies for such Series of Securities, which may include some, all or none of the terms contained in this Article 6. 

Section 6.01 Events of Default. 

Each of the following is an “Event of Default” with respect to the Securities of a Series: 

(1) default for 30 days in the payment when due of interest on such Series of Securities; 

(2) default in payment when due of the principal of, or premium, if any, on such Series of Securities;

of the applicable Series of Securities then outstanding; 

  
 -35- 

 (4) default under any document evidencing any indebtedness for borrowed
money by the Company or any guarantor of such Securities, whether such indebtedness now exists or is created after the applicable 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
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 this Indenture, any Subsidiary
Guarantee of the Securities of such Series 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 Guarantee(s) of the Securities of such Series; and 

(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 

  
 -36- 

 
(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

(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 as to such Series, at any time, cease to be a valid and perfected security interest or shall be declared invalid or unenforceable by a court of
competent jurisdiction 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 such Series of Securities that are outstanding,
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 in respect of such Series of Securities is invalid or
unenforceable as it pertains to such Series of Securities. 
 Section 6.02 Acceleration. 

In the case of an Event of Default with respect to Securities of any Series pursuant to Section 6.01(6), principal of
and accrued and unpaid interest on all the Securities of such Series that are outstanding will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of
at least 30% in principal amount of such Series of Securities that are outstanding may declare the principal of and accrued and unpaid interest on all the Securities of such Series to be due and payable immediately. 

Section 6.03 Waiver of Past Defaults. 

Holders of not less than a majority in aggregate principal amount of the applicable Series of Securities 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 

  
 -37- 

 
a continuing Default or Event of Default in the payment of interest on or principal of, such Series of Securities (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding of the applicable Series of Securities may rescind an acceleration and its consequences, including any related payment default that resulted from such
acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon. 
 Section 6.04 Control by Majority. 

Subject to the terms of the Collateral Trust Agreement, Holders of a majority in principal amount of the applicable Series of Securities that
are then outstanding may direct the Trustee in its exercise of any trust or power in respect of such Series of Securities. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or the applicable Series of
Securities or, subject to Section 7.01 and Section 7.02, that the Trustee determines is unduly prejudicial to the rights of other Holders of such Series of Securities or would involve the Trustee
in personal liability; 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 of any Series of Securities 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
this Indenture at the request or direction of any Holders of a Series of Securities 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 Security may pursue any remedy with respect to this 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 such Series of Securities 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 such Series of
Securities that are then outstanding have not given the Trustee a direction inconsistent with such request within such 60-day period; and 

  
 -38- 

 (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 Securities of a Series 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 Securities 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 the Note Documents, including payment of all
compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders of Securities for amounts due and unpaid on the Securities for principal, premium, if any, and
interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities 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 Securities 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 

  
 -39- 

 
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 hereof. No
provision of this 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 Securities 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.

the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs. 
 (b) Except during the continuance of an Event of Default:

 (2) the Trustee will not be liable for any error
of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

request or direction. 
 (g) In no event shall the Trustee be responsible or liable for special, indirect, punitive, or consequential loss
or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

  
 -41- 

 (h) The Trustee shall not be deemed to have notice of any Default or Event of Default unless
a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the
Securities of a particular Series and this Indenture. 
 (i) The rights, privileges, protections, immunities and benefits given to the
Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder as Registrar and Paying Agent, and each Agent, Custodian and other Person employed to
act hereunder. 
 (j) The Trustee may request that the Company and each Subsidiary Guarantor deliver an Officer’s Certificate setting
forth the names of individuals and/or titles of Officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any Person authorized to sign an Officer’s Certificate,
including any Person specified as so authorized in any such certificate previously delivered and not superseded. 
 (k) Notwithstanding any
provision herein to the contrary, in no event shall the Trustee be liable for any failure or delay in the performance of its obligations under this Indenture because of circumstances beyond its control, including, but not limited to, nuclear or
natural catastrophes or acts of God, flood, war (whether declared or undeclared), terrorism, fire, riot, strikes or work stoppages for any reason, embargo, government action, including any laws, ordinances, regulations or the like which restrict or

(l) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole
cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

 (n) The
Trustee shall have no duty (A) to see any recording, filing, or depositing of this Indenture or any Note Security Document, or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of
such recording or filing or depositing, or to any re-recording, refiling, or redepositing of any thereof, or otherwise 

  
 -42- 

 
monitoring the perfection, continuation of perfection, or the sufficiency or validity of any security interest in or related to any Collateral or (B) to see to the payment or discharge of
any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Collateral. 

(o) The Trustee shall have no obligation whatsoever to assure that the Collateral exists or is owned by any Grantor or is cared for,
protected, insured or has been encumbered, or that any Liens on the Collateral have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether
the property constituting collateral intending to be subject to the interest and the interest of the Note Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or
sufficiency thereof or title thereto. 
 (p) The Trustee shall have no duty to monitor the performance or actions of the Collateral Trustee.
The Trustee shall have no responsibility or liability for the actions or omissions of the Collateral Trustee. In each case that the Trustee is requested hereunder or under any of the Note Security Documents to give direction or provide any consent
or approval to the Collateral Trustee, the Company or to any other party, the Trustee may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding applicable Series of Securities. If the Trustee requests
direction from the Holders of a majority in aggregate principal amount of the then outstanding applicable Series of Securities with respect to giving any direction to the Collateral Trustee, the Trustee shall be entitled to refrain from giving such
direction unless and until the Trustee shall have received direction from the Holders of a majority in aggregate principal amount of the then outstanding Securities, and the Trustee shall not incur liability to any Person by reason of so refraining.

 (q) The Trustee shall be under no obligation to effect or maintain insurance or to renew any policies of insurance or to inquire as to

payment of any taxes or assessments, or to require any such payment be made. 
 Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with either 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 this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. 

Section 7.04 Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of any offering materials, the Note
Documents, the Securities or any Subsidiary Guarantee; it shall not be accountable for the Company’s use of the proceeds from the 

  
 -43- 

 
Securities or any money paid to the Company or upon the Company’s direction under any provision of this Indenture; it will not be responsible for the use or application of any money received
by any Paying Agent other than the Trustee; and it will not be responsible for any statement or recital herein or any statement in the Securities, any Subsidiary Guarantee or any other document in connection with the sale of the Securities or
pursuant to this Indenture other than its certificate of authentication. 
 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail or deliver electronically to
Holders of the applicable Series of Securities a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on, any
Security, the Trustee may and shall be protected in withholding the notice if and so long as it in good faith determines that withholding the notice is in the interests of the Holders of the applicable Series of Securities. 

Section 7.06 Compensation and Indemnity. 

(a) The Company and any Subsidiary Guarantors, jointly and severally, shall pay to the Trustee from time to time reasonable compensation, as
agreed in writing from time to time, for its acceptance and administration of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a Trustee of an express trust. The Company and any
Subsidiary Guarantors, jointly and severally, shall reimburse the Trustee promptly upon request for all reasonable and documented disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such
expenses will include the reasonable and documented compensation, disbursements and expenses of the Trustee’s agents and counsel. 

(b) The Company and any Subsidiary Guarantor, jointly and severally, will indemnify the Trustee and hold it harmless from and against any and
all losses, liabilities, claims, damages, costs or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties or the exercise of its rights under this Indenture, each Supplemental Indenture and any
Subsidiary Guarantees and with respect to each Series of Securities, including the reasonable and documented costs and expenses of enforcing this Indenture, each Supplemental Indenture and any Subsidiary Guarantees against the Company and any
Subsidiary Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Company, any Subsidiary Guarantors, any Holder or any other Person) or liability in connection with the
exercise or performance of any of its powers or duties under this Indenture and each Supplemental Indenture, except to the extent any such loss, liability or expense may be attributable to its own gross negligence or bad faith or willful misconduct.
The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any Subsidiary Guarantors of their obligations hereunder. The Company or any
such Subsidiary Guarantor shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company and/or any Subsidiary Guarantors shall pay the reasonable fees and expenses of such counsel.
Neither the Company nor any Subsidiary Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 

  
 -44- 

 (c) When the Trustee incurs expenses or renders services after an Event of Default specified
in clause (6) of Section 6.01 hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law. 
 (d) The Company’s and Subsidiary Guarantors’ obligations under this Section 7.06
shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture with respect to any Series of Securities, the complete satisfaction and discharge of this Indenture, any termination of this Indenture or any
Supplemental Indenture, including any termination or rejection of this Indenture or any Supplemental Indenture in any insolvency or similar proceeding, and the repayment of all the Securities. 

Section 7.07 Replacement of Trustee. 

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.07. 
 (b) The Trustee may resign at any time, with
respect to the Securities of one or more Series, and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of a majority in aggregate principal amount of the then outstanding Securities of any Series may
remove the Trustee with respect to that Series by so notifying the Trustee and the Company in writing not less than 30 days prior to the effective date of such removal. The Company may remove the Trustee with respect to the Securities of one or
more Series if: 
 (1) the Trustee fails to comply with Section 7.09 hereof; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee with respect to Securities of any one or more Series
for any reason, the Company will promptly appoint a successor Trustee with respect to such Series. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Securities
of such Series may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
 (d) If a successor Trustee with
respect to the Securities of any one or more Series does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring or removed Trustee, the Company, or the Holders of at least 10% in aggregate principal amount
of the then outstanding Securities of the applicable Series may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

  
 -45- 

 (e) If the Trustee, after written request by any Holder who has been a Holder for at least
six months, fails to comply with Section 7.09 hereof, such Holder may petition at the expense of the Company any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee with respect to each Series of Securities for which it is acting as Trustee under this
Indenture. The successor Trustee will mail or deliver electronically a notice of its succession to Holders of each such Series. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee. 

(g) The retiring Trustee shall have no responsibility or liability for any action or inaction of a successor Trustee. 

Section 7.08 Successor Trustee by Merger, etc. 

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including this
transaction) to, another corporation, the successor corporation without any further act will be the successor Trustee.

 ARTICLE 8 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

For purposes of this Indenture, Article 8 hereof provides the terms upon which legal defeasance and covenant defeasance can occur. For
purposes of any Series of Securities issued under this Indenture, the Supplemental Indenture in respect of such Series of Securities will specify the terms upon which legal defeasance and covenant defeasance can occur for such Series of Securities,
which may include some, all or none of the terms contained in this Article 8. 
 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 a Series of Securities upon compliance with the conditions set forth below in this Article 8.

  
 -46- 

 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 of such Securities, if any, 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 a Series of Securities (including the Subsidiary Guarantees, if any) 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 any Subsidiary Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by such Series of Securities (including any
Subsidiary Guarantees with respect to such Series of Securities), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections hereof 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 Securities to receive payments in respect of the principal of, or interest or premium on, such Securities when such payments are due from the trust referred to in Section 8.04 hereof; 

(2) the Company’s obligations with respect to such Securities under Article 2 and
Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties, indemnities and immunities of the
Trustee hereunder, and the Company’s and any 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 of such Securities, if any, shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of
its or their obligations under the covenants specified in a Supplemental Indenture with respect to Securities of the applicable Series on and after the date the conditions set forth in Section 8.04 hereof are satisfied
(hereinafter, “Covenant Defeasance”), and such Series of Securities will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of the Holders of such Series of
Securities (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 such Series of Securities will not be deemed
outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to such Series of Securities and any Subsidiary Guarantees with respect to such Series of 

  
 -47- 

 
Securities, the Company and any 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 this Indenture and such Securities 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 a Series of Securities under
either Section 8.02 or Section 8.03 hereof: 
 (1) the Company must
irrevocably deposit with the Trustee for such Securities, in trust, for the benefit of the Holders of such Series of Securities, 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 Securities 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 Securities 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 for such Securities 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 applicable 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 such Series of Securities 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 for such Securities an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of such Series of
Securities 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; 

  
 -48- 

 (4) no Default or Event of Default with respect to such Series of Securities
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 this 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 for such Securities 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 

(7) the Company must deliver to the Trustee for such Securities 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 Securities of any Series shall be held in trust and applied by the Trustee, in accordance
with the provisions of such Securities and this 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 Securities 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 Securities of the applicable Series. 
 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. 

  
 -49- 

 Section 8.06 Repayment to the Company. 

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 Series of Securities 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 Holders of such Securities 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. 
 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 any 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 Security following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities 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 Securities. 

Notwithstanding Section 9.02 hereof, the Company 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 Securities in addition to or in place of certificated Securities; 

(3) to provide for the assumption of the Company’s or, if any, 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, if any, Subsidiary Guarantor’s assets pursuant to Article 5 of this Indenture (if applicable); 

  
 -50- 

 (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 this Indenture of any such Holder; 
 (5) to comply
with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 
 (6) to
evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee with respect to the Securities of one or more Series pursuant to the requirements thereof; 

(7) to provide for the issuance of Securities of any Series in accordance with the limitations set forth in this Indenture;

 (8) to allow any Subsidiary Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to
the Securities; 
 (9) to make, complete or confirm any grant of Collateral permitted or required by any of the Note
Documents; 
 (10) 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 
 (11) as provided in
Section 12.03(c) and Section 12.03(e) 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 and Section 9.05 hereof the Trustee shall join with the Company and any 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 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 or immunities under this Indenture or otherwise. 

Section 9.02 With Consent of Holders of Securities. 

(a) Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement the Note
Documents with the consent of the Holders of at least a majority in principal aggregate amount of the applicable Series of Securities then outstanding (including, without limitation, consents obtained in connection with a purchase, or tender offer
or exchange offer for, the Securities), 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
Securities, 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 

  
 -51- 

 
consent of the Holders of a majority in principal aggregate amount of the applicable Series of Securities then outstanding (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for, such Securities). Section 2.08 hereof shall determine which Securities are considered to be “outstanding” for purposes of this
Section 9.02. 
 (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 applicable Series of Securities as aforesaid, and upon receipt by the Trustee of the documents described in
Section 11.02 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 unless such
amended or supplemental indenture or any amendment of or supplement to any Note Document directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but
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 of the applicable Series of Securities 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, the Holders of a majority in aggregate principal amount of
the applicable Series of Securities then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of the Note Documents as to such Series of Securities. However, without the consent of each
Holder of the applicable Series of Securities affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any such Securities held by a
non-consenting Holder): 
 (1) reduce the principal amount of Securities of such
Series whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed
maturity of any such Security or alter the provisions with respect to the redemption of such Securities (other than 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 such Security; 

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium on such Series of Securities
(except a rescission of acceleration of such Securities by the Holders of a majority in aggregate principal amount of such Series of Securities and a waiver of the payment default that resulted from such acceleration); 

  
 -52- 

 (5) make any Security payable in currency other than that stated in the
Securities; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of
such Holders to receive payments of principal of, or interest or premium on such Series of Securities; 
 (7) waive a
redemption payment with respect to any Security; or 
 (8) make any change to Section 9.01 hereof
and this Section 9.02. 
 (e) Without the consent of the Holders of at least 66 2/3% in aggregate principal amount
of the applicable Series of Securities then outstanding, no amendment or waiver may (A) make any change in any Note Security Documents or the provisions in this 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 such Series of Securities or (B) change or alter the priority of the Liens securing the Obligations in
respect of such Series of Securities in any material portion of the Collateral in any way adverse to the Holders of such Securities in any material respect, other than, in each case, as provided under the terms of the Note Security Documents. 

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 Security is a continuing consent by the Holder of
a Security and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder of a Security
or subsequent Holder of a Security may revoke the consent as to its Security 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 Securities. 

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

Failure to make the appropriate notation or issue a new Security 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 or immunities of the Trustee. The Company may not sign an amended or supplemental indenture or other

  
 -53- 

 
amendment of or supplement to any Note Document until the Board of Directors of the 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 hereof) 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 Note Documents. 

ARTICLE 10 
 SATISFACTION AND
DISCHARGE 
 For purposes of this Indenture, Article 10 hereof provides the terms upon which satisfaction and discharge can occur.
For purposes of any Series of Securities issued under this Indenture, the Supplemental Indenture in respect of such Series of Securities will specify the terms upon which satisfaction and discharge can occur for such Securities, which may include
some, all or none of the terms contained in this Article 10. 
 Section 10.01 Satisfaction and Discharge. 

This Indenture will be discharged and will cease to be of further effect as to all Securities of a Series issued hereunder, when: 

(1) either: 

(A) all such Securities that have been authenticated, except lost, stolen or destroyed Securities that have been replaced or
paid and Securities 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 such Securities 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 Securities 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, as applicable, of such Securities is a party or by which the Company or any such Subsidiary Guarantor, as applicable, is bound; 

  
 -54- 

 (3) the Company or any Subsidiary Guarantor of such Securities has paid or
caused to be paid all sums payable by it with respect to such Series of Securities under this Indenture; and 
 (4) the
Company has delivered irrevocable written instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Securities of such Series 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 for such Securities stating that all conditions
precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture as to a
Series of Securities issued hereunder, if money has been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 10.01, the provisions of Section 10.02 and
Section 8.06 hereof will survive. In addition, nothing in this Section 10.01 will be deemed to discharge any provisions related to any other Series of Securities or those provisions of
Section 7.06 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture as to a Series of Securities issued hereunder. 

Section 10.02 Application of Trust Money. 

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to
Section 10.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Securities and this 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 10.01 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 applicable Subsidiary Guarantor’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01
hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such
Securities to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 ARTICLE 12 

COLLATERAL AND SECURITY 
 For
purposes of this Indenture, Article 12 hereof provides the terms upon which any Series of Securities will be secured by Collateral. For purposes of any Series of Securities issued under this Indenture, the Supplemental Indenture in respect of
such Series of Securities will specify the terms upon which such Securities will be secured by Collateral, which may include some, all or none of the terms contained in this Article 12. 

Section 12.01 Grant of Security Interest. 

(a) The due and punctual payment of the Obligations on the Securities and the Obligations of, if any, the Subsidiary Guarantors under the
Subsidiary Guarantees, when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest,
if any (to the extent permitted by law), on the Securities, any Subsidiary Guarantees and performance of all other obligations of the Company and the Guarantors to the Holders or the Trustee under the Note Documents, according to the terms hereunder
or thereunder (collectively, the “Notes Obligations”), are secured, as provided in the Note Security Documents. The Company hereby consents and agrees, and shall cause each, if any, of the Subsidiary Guarantors, to be bound by the
terms of the Note Security Documents to which they are parties, as the same may be in effect from time to time, and agree to perform their obligations thereunder in accordance therewith. The Company hereby agrees, and shall cause the Subsidiary
Guarantors, if any, to agree, that the Collateral Trustee shall hold the Collateral (directly or through co-trustees or agents) on behalf of and for the benefit of all of the Holders and the other holders of Priority Lien Obligations. 

(b) Each Holder, by its acceptance of any Securities and, if any, the Subsidiary Guarantees, consents and agrees to the terms of the
Collateral Trust Agreement and the Note Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and amendments to the Note Security Documents) as the same may be in effect or may be
amended from time to time in accordance with their terms and authorizes and appoints Delaware Trust Company (or any successor thereto as contemplated by the Collateral Trust Agreement) as the Collateral Trustee. Each Holder, by accepting any
Securities and, if any, the Subsidiary Guarantees of the Subsidiary Guarantors, authorizes and directs the Collateral Trustee to enter into any Note Security Documents to the extent not already entered into (including any amendments thereto and any
security documents to secure additional Priority Lien Debt in accordance with the Collateral Trust Agreement) and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof.
Each of the Trustee, the Collateral Trustee and the Holders, by accepting the Securities and, if any, the Subsidiary Guarantees of the Subsidiary Guarantors, acknowledges that, as more fully set forth in the Note Security Documents, the Collateral
as now or hereafter constituted shall be held for the benefit of all the holders of Priority Lien Obligations, the Collateral Trustee 

  
 -60- 

 
and the Trustee, and the Lien of this Indenture and the Note Security Documents is subject to and qualified and limited in all respects by the Note Security Documents and actions that may be
taken thereunder. 
 Section 12.02 Post-Date of this Indenture Collateral Requirements. 

(a) With respect to each Series of Securities, the Company shall, or shall cause the applicable Subsidiary Guarantor, if any, to, use its
commercially reasonable efforts to as soon as reasonably practicable, but in no event later than 90 days, after the applicable Issue Date execute and deliver to the Collateral Trustee as mortgagee or beneficiary, as applicable (with a copy to the
Trustee), such Note Security Documents, and any supplements or amendments related thereto, together with satisfactory evidence of the completion (or satisfactory arrangements for the completion) of all recordings and filings of such Note Security
Documents in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith) as may be necessary to create a valid, perfected first-priority Lien (subject to the applicable Permitted Liens
described in the applicable Supplemental Indenture), securing the Securities, Subsidiary Guarantees (if any) and Security Obligations, on or against, except as otherwise provided in the Collateral Trust Agreement or the other Note Security
Documents, the Collateral. 
 (b) Any Note Security Documents entered into with respect to a Series of Securities after the applicable Issue
Date shall be substantially in the form of the corresponding security document securing the Priority Lien Obligations in place on, or required to be in place within 90 days after, the applicable Issue Date, or, to the extent there is no such
corresponding security document, in the form of corresponding security documents establishing Liens securing comparable debt securities, in each case, with such deletions or modifications of representations, warranties and covenants as are customary
in the business of the Company, as determined in good faith by the Company. 
 Section 12.03 Further Assurances; Liens on Additional Property

 (a) With respect to each Series of Securities, the Company and each, if any, of the Subsidiary Guarantors shall do or cause to be done all
acts and things that may be required, or that the Collateral Trustee (acting at the written direction of the Controlling Priority Lien Representative) from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds,
for the benefit of the holders of Priority Lien Obligations, duly created and enforceable and perfected first-priority Liens upon the Collateral (including any property or assets constituting Collateral that are acquired or otherwise become, or are
required by any Priority Lien Document to become, Collateral after the applicable Issue Date), in each case, as contemplated by, and with the Lien priority required under, the Priority Lien Documents and in connection with any merger, consolidation
or sale of assets of the Company or any Subsidiary Guarantor, the property and assets of the Person which is consolidated or merged with or into the Company or any Subsidiary Guarantor, to the extent that they are property or assets of the types
which would constitute Collateral under the Note Security Documents and, to the extent such property or assets are not otherwise required or permitted to be released as Collateral in connection with such transaction, shall be treated as
after-acquired property and the Company or such Subsidiary Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Priority Liens, in the manner and to the extent required under the
Priority Lien Documents. 

  
 -61- 

 (b) At any time and from time to time, the Company and each of the other Grantors will
promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents, and take such other actions as may be reasonably required, or that the Collateral Trustee (acting at the written direction of
the Controlling Priority Lien Representative) or any Priority Lien Representative may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Priority
Lien Documents for the benefit of the holders of Priority Lien Obligations. 
 (c) Notwithstanding anything to the contrary in any Note
Document (but subject to Section 12.03(d) below), to the extent that any portion of the Collateral consists of Indenture Principal Property, (i) the aggregate principal amount of Specified Secured Obligations at any
time shall be limited, automatically and without further action by any Person, so that such amount does not exceed the Indenture Principal Property Cap at such time and (ii) consistent with Sections 12.01(b) and 12.04 hereof, in
the event that Specified Secured Obligations (other than Priority Lien Obligations) are incurred, each of the Trustee and the Collateral Trustee is authorized (without the consent of the Holders) to amend the Note Documents to give effect to such
incurrence, including to provide that the aggregate principal amount of Priority Lien Obligations constituting Specified Secured Obligations shall not exceed its pro rata portion of the aggregate principal amount of Specified Secured Obligations.
For the avoidance of doubt, in executing any such amendment, each of the Trustee and the Collateral Trustee shall be entitled to receive and rely on (without further inquiry) an Officer’s Certificate of the Company (together with any other
opinions of counsel or Officer’s Certificates to which the Trustee or Collateral Trustee may be entitled under the Note Documents) to the effect that any such amendment is consistent with the terms and requirements of this
Section 12.03(c). 
 (d) To the extent that any event occurs that activates or triggers any of the “equal and
ratable” security provisions of the liens covenant in any Reference Indenture (each, an “Indenture Trigger Event”), then, at the time that the Company or any Restricted Subsidiary grants a Lien on Indenture Principal Property
to holders of Specified Indebtedness as to which such Indenture Trigger Event has occurred in order to satisfy the requirements of such “equal and ratable security” provisions, the Indenture Principal Property Cap, notwithstanding anything
to the contrary in any Note Document, shall no longer apply to the Priority Lien Obligations constituting Specified Secured Obligations and the full amount of the Priority Lien Obligations shall be secured by all of the Collateral, including,
without limitation, the full amount and value of all Indenture Principal Property, without any reference to, or application of, the Indenture Principal Property Cap. 

(e) In addition, in the event that all of the Reference Indentures are terminated and/or all conditions of satisfaction and discharge of all
of the Reference Indentures have occurred and/or the liens covenant in all of the Reference Indentures has been “stripped” or deleted (by way of amendment, supplement or otherwise), notwithstanding anything to the contrary in any Note
Document, (i) the Indenture Principal Property Cap shall no longer apply to the Priority Lien Obligations constituting Specified Secured Obligations and the full amount of the Priority 

  
 -62- 

 
Lien Obligations shall be secured by all of the Collateral, including, without limitation, the full amount and value of all Indenture Principal Property, without any reference to, or application
of, the Indenture Principal Property Cap, (ii) the definitions and provisions in this Agreement utilizing the term Reference Indenture shall be interpreted as if such Reference Indentures were in effect but with no cap, restriction or
limitation on the amount of the Priority Lien Obligations that may be secured by any Indenture Principal Property and (iii) consistent with Sections 12.01(b) and 12.04 hereof, the Trustee and the Collateral Trustee are authorized
(without the consent of the Holders) to amend the Note Documents to eliminate the restrictions on Specified Secured Obligations that may be secured by the Indenture Principal Property contemplated by Section 12.03(c)(i),
replace any definitions used herein that are imported from the Reference Indentures with substantially equivalent definitions that do not import any terms from a Reference Indenture and effectuate the fall away of the Indenture Principal Property
Cap. For the avoidance of doubt, in executing any such amendment, each of the Trustee and the Collateral Trustee shall be entitled to receive and rely on (without further inquiry) an Officer’s Certificate of the Company (together with any other
opinions of counsel or Officer’s Certificates to which the Trustee or Collateral Trustee may be entitled under the Note Documents) to the effect that any such amendment is consistent with the terms and requirements of this
Section 12.03(e). 
 Section 12.04 Collateral Trust Agreement 

This Article 12 and the provisions of each of the Note Security Documents are subject to the terms, conditions and benefits set forth in
the Collateral Trust Agreement. The Company consents to and agrees to be bound by, and shall cause each Subsidiary Guarantor to be bound by, the terms of the Collateral Trust Agreement, as the same may be in effect from time to time, and to perform
its obligations thereunder in accordance with the terms therewith. Each Holder, by its acceptance of the a Series of Securities (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Trust
Agreement, (b) authorizes and instructs the Trustee on behalf of the Holders of the Securities to enter into a Collateral Trust Joinder – Additional Debt (the “Joinder”) and Additional First Lien Secured Party Consent (the
“First Lien Consent”), in each case, dated as of the applicable Issue Date, and (c) authorizes and instructs the Collateral Trustee to enter into the First Lien Consent and to acknowledge the Joinder and Additional Secured Debt
Designation dated as of the applicable Issue Date. In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Collateral Trust Agreement in accordance with its terms with the consent of
the parties thereto or otherwise in accordance with its terms, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Obligations and add other parties (or any authorized agent or trustee therefor) holding
such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the other Priority Lien Debt then outstanding, to the extent permitted by the
Priority Lien Documents. The Trustee and the Collateral Trustee shall be entitled to rely on an Officer’s Certificate or an Opinion of Counsel certifying that any such amendment is authorized or permitted under the Note Documents and that all
conditions precedent thereto have been satisfied. 

  
 -63- 

 Section 12.05 Releases of Collateral 

(a) The Liens on the Collateral of this Indenture will no longer secure a Series of Securities outstanding under this Indenture or a
Supplemental Indenture or any other Note Obligations with respect to such Series of Securities, and the right of the Holders of such Series of Securities to the benefits and proceeds of the Liens on the Collateral will terminate and be discharged,
in each case, automatically and without the need for any further action by any Person: 
 (1) in whole, upon the full and
final payment and performance of the Obligations of the Company and the Subsidiary Guarantors with respect to such Series of Securities under the Note Documents; 

(2) in whole, upon Legal Defeasance or Covenant Defeasance of such Series of Securities pursuant to Article 8 hereof or
upon the satisfaction and discharge of this Indenture with respect to such Series of Securities in accordance with Article 10 hereof; 

(3) in whole or in part, as applicable, upon receipt of the consent of Holders of the requisite percentage of such Series of
Securities in accordance with Article 9 hereof;

otherwise disposed of by the Company or any Subsidiary Guarantor in a transaction or other circumstance made in compliance with the applicable Supplemental Indenture and the Note Security Documents at the time of such sale, transfer or disposition;

 (5) in whole, with respect to the Collateral owned by any Subsidiary Guarantor, upon the release of the Subsidiary
Guarantee of such Subsidiary Guarantor in accordance with the terms of the applicable Supplemental Indenture; and 
 (6) in
whole, upon the occurrence of an Investment Grade Event with respect to such Series of Securities; provided, however, that in the event that on any subsequent date (the “Reversion Date”) any two of the three Rating Agencies
withdraw their Investment Grade rating of the senior, unsecured, long-term debt securities of the Company or downgrade such rating below Investment Grade, then (i) the Company and any Subsidiary Guarantors will be required to secure the Series
of Securities with the Collateral within 60 days after the Reversion Date and (ii) will thereafter be subject to the terms of the Note Documents and the Note Security Documents with respect to future events; provided that clause
(i) will not apply to property and other assets released by the Company under any other subsection of this Section 12.05(a). For the avoidance of doubt, in the event of any such reinstatement pursuant to clause
(i) hereof, (A) no action taken or omitted to be taken by the Company or any Subsidiary Guarantors after a Release Event and before the Reversion Date will give rise to a Default, Event of Default or other breach under this Indenture, the
Securities or, if any, the Subsidiary Guarantees and (B) none of the Company or any Subsidiary Guarantor will bear any liability for any actions taken or events occurring after a Release Event and before the Reversion Date, or any actions taken
at any time pursuant to any contractual obligation arising after a Release Event and before the Reversion Date; provided that all Liens incurred after a 

  
 -64- 

 
Release Event and before the Reversion Date will be classified to have been incurred or issued pursuant to the applicable clause of the definition of “Permitted Lien” in the applicable
Supplemental Indenture.

subject to the conditions set forth in Section 4.1 of the Collateral Trust Agreement.

Company, accompanied by an Officer’s Certificate and Opinion of Counsel to the effect that the conditions precedent to such release have been satisfied) to release and re-convey to the Company or any
other Grantor, as the case may be, the applicable portion of the Collateral that is authorized to be released pursuant to Section 12.05, and shall deliver such Collateral in its possession to the Company or any other
Grantor, as the case may be, including, without limitation, executing and delivering releases and satisfactions wherever required. 
 Section 12.07

(3) to take any other action whatsoever with regard to any or all of the Note Security Documents, the Liens created thereby or
the Collateral. 
 Notwithstanding anything to the contrary contained in the Collateral Trust Agreement, the Collateral Trustee will not commence any
Enforcement Action or otherwise take any action or proceeding against any of the Collateral unless and until it shall have been directed by written notice from the Controlling Priority Lien Representative and then only in accordance with the
provisions of the Collateral Trust Agreement.

The Company and any Subsidiary Guarantors shall: 

  
 -65-

arrangements or with insurance companies that the Company believes (in the good faith judgment of the management of the Company, as applicable) are financially sound and responsible at the time the relevant coverage is placed or renewed, insurance
in at least such amounts (after giving effect to any self-insurance which the Company believes (in the good faith judgment of management of the Company, as applicable) is reasonable and prudent in light of the size and nature of its business) and
against at least such risks (and with such risk retentions) as the Company believes (in the good faith judgment of management of the Company, as applicable) is reasonable and prudent in light of the size and nature of its business and the
availability of insurance on a cost-effective basis; and 
 (b) maintain such other insurance as may be required by law. 

Section 12.09 Purchaser Protected. 

No purchaser or grantee of any property or rights purporting to be released from the Liens in favor of the Collateral Trustee shall be bound to

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

Section 2.05 Holder Lists. 
 The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven

requirements. 

  
 -44- 

 In the event of partial redemption by lot, the particular Notes of the Series to be redeemed
shall be selected, unless otherwise provided herein, not less than 10 nor more than 60 days prior to the redemption by the Trustee from the outstanding Notes of such Series not previously called for redemption. 

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for
partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in minimum amounts of $2,000 or whole multiples of $1,000 in excess of $2,000; except that if all of the Notes of a Holder of any Series
are to be redeemed, the entire outstanding amount of Notes of such Series held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of the Indenture that apply to a Series of
Notes called for redemption also apply to portions of Notes called for redemption. 
 No Notes of $2,000 or less shall be redeemed in part.
Notices of redemption shall be mailed by first-class mail or delivered electronically at least 10 but not more than 60 days before the redemption date to each Holder to be redeemed at its registered address, except that redemption notices may
be mailed or delivered electronically more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. 

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount
of that Note that is to be redeemed. In the case of certificated Notes, a new Note in principal amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder upon cancellation of the original Note. Notes
called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption unless the Company defaults in making the applicable redemption
payment. 
 Section 3.03 Notice of Redemption. 

At least 10 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first-class
mail or delivered electronically, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that, notwithstanding anything to the contrary in Section 3.07 below, redemption
notices may be mailed or delivered electronically more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article 8 or
Article 11 of this Supplemental Indenture. 
 The notice will identify the Notes of the Series to be redeemed and will state: 

(1) the redemption date; 

(2) the redemption price;

 -45- 

 (4) the name and address of the Paying Agent; 

(5) that Notes of such Series called for redemption must be surrendered to the Paying Agent to collect the redemption price;

redemption ceases to accrue on and after the redemption date; 
 (7) the applicable section of this Supplemental Indenture or
the Notes pursuant to which the Notes of such Series called for redemption are being redeemed; 
 (8) that no representation
is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and 

(9) if such redemption is subject to the satisfaction of one of more conditions precedent, such notice shall state that, in the
Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or 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. 

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense;
provided, however, that the Company has delivered to the Trustee, at least 10 days prior to the redemption date (or such shorter period as the Trustee in its sole discretion may allow), an Officer’s Certificate requesting
that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Any redemption and notice thereof may, in the Company’s discretion, be subject to the satisfaction of one or more conditions precedent.

 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed or delivered electronically in accordance with Section 3.03 hereof, Notes of the
Series called for redemption become, subject to any conditions precedent set forth in the notice of redemption, irrevocably due and payable on the redemption date at the redemption price. 

Section 3.05 Deposit of Redemption Price. 

One Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of, accrued interest to but excluding the redemption date, and premium, if any, on all Notes to be redeemed on that date. Promptly after the Company’s written request, the Trustee or the Paying Agent shall promptly return to
the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, accrued interest, and premium, if any, on, all Notes to be redeemed. 

  
 -46- 

 If the Company complies with the provisions of the preceding paragraph, on and after the
redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption. 
 If a Note is redeemed on or
after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note
called for redemption is not so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid,
and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06 Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon receipt of a Company Order, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 
 Section 3.07
Optional Redemption. 
 (a) At any time prior to the Par Call Date for the applicable Series of Notes, 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 Series of Notes redeemed, plus 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 such Series 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 is not prohibited, however, from acquiring the Notes in market transactions by means other than a redemption, whether pursuant to a tender offer or otherwise,
if such action does not otherwise violate the Indenture. 

  
 -47- 

 (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 the Notes of either Series, including a Change of Control Offer, if

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

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

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 Notes of such Series 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.

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 Supplemental Indenture, the Note
Security Documents and the other Priority Lien Documents.

 Section 6.04 Control by Majority. 

Subject to the terms of the Collateral Trust Agreement, Holders of a majority in principal amount of the applicable Series of 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 applicable Series of 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 of such Series of Notes or would involve the Trustee in
personal liability; 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 of the Series of Notes 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 of a Series of Notes 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 such Series of 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 such Series of 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 

  
 -58- 

 
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.

elect to have either Section 8.02 or Section 8.03 hereof be applied to a Series of 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 a Series of 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 such Series of Notes (including the Subsidiary Guarantees with respect to such Series
of Notes), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections hereof 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. 

  
 -60- 

 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 a Series of Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied
(hereinafter, “Covenant Defeasance”), and such Series of Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of the Holders of such Series of Notes
(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 such Series of Notes will not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to such Series of Notes and Subsidiary Guarantees with respect to such Series of 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 a Series of 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 such Series of 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 such Series of 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; 

  
 -61- 

 (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 such Series of 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 such Series of 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 

(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. 

  
 -62- 

 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. 

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. 
 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: 

  
 -63- 

 (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 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; 

(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

  
 -64- 

 
to any Note Document authorized or permitted by the terms of this 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 or immunities under this
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 applicable Series of 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 applicable Series of 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. 
 (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 applicable Series of 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 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 or
immunities under this 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 of the applicable Series of Notes 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 applicable Series of 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 as to such Series of Notes. However, without the
consent of each Holder of the applicable Series of 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): 

  
 -65- 

 (1) reduce the principal amount of Notes of such Series whose Holders must
consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any such Note
or alter the provisions with respect to the redemption of such Notes (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 such Note; 

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium on such Series of Notes (except
a rescission of acceleration of such Notes by the Holders of a majority in aggregate principal amount of such Series of 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 such Series of Notes; 
 (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 of such Series. 
 (e) Without the consent of the Holders of at least 66 2/3% in aggregate principal amount of the applicable Series of
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 such Series of Notes or (B) change or alter the priority of the Liens securing the Obligations in respect of such Series of 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. 

  
 -66- 

 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 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 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: 

  
 -67- 

 (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. 

(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. 

  
 -68- 

 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. 

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. 

  
 -69- 

 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 of a Series
issued hereunder, when: 
 (1) either: 

(A) all such 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 such 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; 

  
 -70- 

 (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 such Series of Notes under this 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 of such Series 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. 

Notwithstanding the satisfaction and discharge of this Supplemental Indenture as to a Series of 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.
In addition, nothing in this Section 11.01 will be deemed to discharge any provisions related to any other Series of Notes or those provisions of Section 7.06 of the Base Indenture, that, by their
terms, survive the satisfaction and discharge of the Indenture as to a Series of Notes issued hereunder. 
 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 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 3.55% per annum from June 11, 2019 until maturity. The Company shall pay interest semi-annually in arrears on January 15 and July 15 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 January 15, 2020. 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 the January 1 and July 1 (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-1-3- 

 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 Supplemental Indenture dated as
of June 11, 2019 (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 the June 15, 2024, 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 the June 15, 2024, 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 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 tender offer and the Company, or any third party making such a tender offer in lieu of the Company, purchase all of
the Notes validly tendered and not withdrawn by such Holders, 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 tender 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 tender offer, plus, to the
extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, such redemption date. In determining whether 

  
 -A-1-4- 

 
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 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 

  
 -A-1-5- 

 
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 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 than a default specified in clause
(1) or (2) above) for 60 days (or 120 days in the case of the covenant set forth in Section 4.03 of the Indenture) after written notice by the Trustee or Holders of at least 30% in principal amount of the 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 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 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 

  
 -A-1-6- 

 
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 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.

 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.

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 4.30% per annum from June 11, 2019 until maturity. The Company shall pay interest semi-annually in arrears on January 15 and July 15 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 January 15, 2020. 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 the January 1 and July 1 (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-2-3- 

 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 Supplemental Indenture dated as
of June 11, 2019 (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 the April 15, 2029, 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 the April 15, 2029, 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 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 tender offer and the Company, or any third party making such a tender offer in lieu of the Company, purchase all of
the Notes validly tendered and not withdrawn by such Holders, 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 tender 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 tender offer, plus, to the
extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, such redemption date. In determining whether 

  
 -A-2-4- 

 
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 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 

  
 -A-2-5- 

 
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 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 than a default specified in clause
(1) or (2) above) for 60 days (or 120 days in the case of the covenant set forth in Section 4.03 of the Indenture) after written notice by the Trustee or Holders of at least 30% in principal amount of the 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 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 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 

  
 -A-2-6- 

 
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-2-7- 

 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

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.
