THIS SECURITY IS A REGISTERED SECURITY WITHIN THE
MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITORY TRUST COMPANY OR A NOMINEE THEREOF.

 

Unless this Security is presented by an authorized
representative of The Depository Trust Company, a New York corporation (“DTC”), to NSTAR ELECTRIC COMPANY, doing business
as EVERSOURCE ENERGY, or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the
name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (the “Registered Owner”)
(and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER,
PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede &
Co., has an interest herein.

 

NSTAR
ELECTRIC COMPANY, doing business as EVERSOURCE ENERGY, a corporation duly organized and validly existing under the laws of The Commonwealth
of Massachusetts (herein called the “Company,” which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to the Registered Owner, or registered assigns, the principal amount specified
in the title of this security (the “Principal Amount”) on the Stated Maturity, except to the extent redeemed prior to the
Stated Maturity, and to pay interest on said principal sum semi-annually on each Interest Payment Date, commencing March 15, 2023,
at the rate per annum specified in the title of this Security, from the March 15 and September 15, as the case may be, next
preceding the date of this Security to which interest has been paid unless the date hereof is a date to which interest has been paid,
in which case from the date of this Security, or unless no interest has been paid on this Security, in which case from the date of initial
issuance until payment of said principal sum has been made or duly provided for and at such rate on any overdue principal and premium
and (to the extent that the payment of such interest shall be legally enforceable) on any overdue installment of interest. If any
Interest Payment Date falls on a day that is not a Business Day, the interest payment will be made on the next Business Day, but such
payment will be deemed to have been made on the date that payment was due. No interest will accrue on the amount payable for the period
from the actual payment date to such next Business Day. The interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, except as otherwise provided in said Indenture, be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the March 1 and September 1, as the case may be, next preceding such March 15
and September 15.

notice to the Registered Owner of this Security; provided that interest shall be paid by wire transfer in immediately available funds
to an account located in the United States of America as the Registered Owner hereof shall designate to the Indenture Trustee in writing
at least 15 Business Days prior to such Interest Payment Date. Any interest not punctually paid or duly provided for shall be payable
as provided in the Indenture.

 

The authentication by the Trustee may be by manual
or electronically transmitted signature.

THE OPTIONAL REDEMPTION PROVISIONS, OF THIS SECURITY SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE. UNLESS THE CERTIFICATE OF AUTHENTICATION HEREON HAS BEEN EXECUTED BY THE TRUSTEE BY

INDENTURE
TRUSTEE’S CERTIFICATE OF AUTHENTICATION

 

This is one of the Securities of the series designated
therein referred to in the within- mentioned Indenture.

 

	 	THE BANK OF NEW YORK

MELLON TRUST COMPANY, N.A.,

as Indenture Trustee

 

	 	By:	 
	 	 	
    Name:

    Title:

 

     

     

    

 

(Reverse of Security)

 

This Security is one of a duly authorized issue
of securities of the Company (herein called the “Securities”) issued under the Indenture, dated as of September 1, 1988,
as supplemented, between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly Bank of Montreal Trust Company), as
Indenture Trustee, to which Indenture and all other indentures supplemental thereto reference is hereby made for a statement of the respective
rights thereunder of the Company, the Indenture Trustee and the Holders of the Securities and the terms upon which the Securities are,
and are to be, authenticated and delivered.

 

This Security is one of the series designated as
the 4.95% Debentures due 2052.

 

Prior to six months prior to the maturity date
(the “Par Call Date”), the Company may redeem the Securities at its option, in whole or in part, at any time, on not less
than 10 nor more than 60 days’ prior notice mailed (or delivered by electronic transmission in accordance with the applicable procedures
of DTC) to the holders of the Securities, at a redemption price (expressed as a percentage of principal amount of the Securities to be
redeemed and rounded to three decimal places) equal to the greater of:

 

(1)(a) the sum of the present values of the
remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Securities matured on the
Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined herein)
plus 25 basis points less (b) interest accrued to the date of redemption date, and

 

(2) 100% of the principal amount of the Securities
to be redeemed,

 

plus, in either case, accrued and unpaid interest
thereon to, but excluding, the redemption date.

 

On or after the Par Call Date the Company may redeem
the Securities, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of
the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

 

The terms which follow, when used in this Security,
shall have the following meanings:

 

“Treasury Rate” means, with respect
to any redemption date, yield determined by the Company in accordance with the following two paragraphs.

 

    i 

     

    

 

The Treasury Rate shall be determined by the Company
after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors
of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent
day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal
Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”)
under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption
or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for
the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining
Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields –
one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury
constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line
basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no
such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity
on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15
shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity
from the redemption date.

 

If on the third business day preceding the redemption
date H.15 TCM or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based
on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business
day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par
Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury
securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date, and one
with a maturity date following the Par Call Date the Company shall select the United States Treasury security with a maturity date preceding
the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States
Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States
Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices
for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the
terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average
of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury
security, and rounded to three decimal places.

 

The Company’s actions and determinations
in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall have no
responsibility to calculate the redemption price.

 

Notice of any redemption will be mailed or electronically
delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before
the redemption date to each holder of notes to be redeemed.

 

In the case of a partial redemption, selection
of the Securities for redemption will be made by lot or pursuant to the applicable depositary’s procedures. No notes of a principal
amount of $2,000 or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates
to the Security will state the portion of the principal amount of the Security to be redeemed. A new Security in a principal amount equal
to the unredeemed portion of the Security will be issued in the name of the holder of the Security upon surrender for cancellation of
the original Security. For so long as the Securities are held by DTC (or another depositary), the redemption of the Securities shall be
done in accordance with the policies and procedures of the depositary.

 

    ii 

     

    

 

On
and after the redemption date interest will cease to accrue on the Securities or portions thereof called for redemption. Prior
to any redemption date, the Company is required to deposit with a paying agent money sufficient to pay the redemption price of and accrued
interest on the Securities to be redeemed on such date.

 

Any
redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, the
completion or occurrence of a related transaction or event, as the case may be, and any notice of redemption made in connection with a
related transaction or event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. If
such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if
applicable, will state that, at the Company’s discretion, the redemption date may be delayed until such time (including more than
60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions
are satisfied (or waived by the Company in its sole discretion), or that such redemption may not occur and such notice may be rescinded
in the event that any or all such conditions are not satisfied (or waived by the Company in its sole discretion) by the redemption date,
or by the redemption date as so delayed, or that such notice may be rescinded at any time in the Company’s discretion if in its
good faith judgment any or all of such conditions will not be satisfied. If any such condition precedent has not been satisfied, the Company
shall provide written notice prior to the close of business on the business day immediately prior to the redemption date. Upon receipt
of such notice, the notice of redemption shall be rescinded or delayed, and the redemption of the Securities shall be rescinded or delayed
as provided in such notice.

 

As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security may be registered on the Security Register of the Company, upon surrender
of this Security for registration of transfer at the office or agency of the Indenture Trustee, as Indenture Trustee and Paying Agent
located at The Bank of New York Mellon Trust Company, N.A., 500 Ross Street, 12th Floor, Pittsburgh, Pennsylvania, 15262, or at such other
office as the Indenture Trustee shall designate by written notice to the Registered Owner of this Security, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company and the Indenture Trustee duly executed by, the Registered Owner
hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series, of any authorized denominations
and for a like aggregate principal amount and tenor, will be issued to the designated transferee or transferees; provided, however, that
the Indenture Trustee will not be required to register the transfer of or exchange any Security that has been called for redemption in
whole or in part except the unredeemed portion of Securities being redeemed in part.

 

    iii 

     

    

 

The Securities of this series are issuable only
in registered form without coupons in minimum denominations of $2,000 or any amount in excess thereof which is an integral multiple of
$1,000. As provided in the Indenture, and subject to certain limitations therein set forth, Securities of this series are exchangeable
for a like aggregate principal amount and tenor of Securities of this series of any authorized denomination, as requested by the Holder
surrendering the same; provided, however, that the Company shall not be required to issue any Securities of this series of a denomination
less than $1,000.

 

No service charge (to the Holder) will be made
for any such transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

 

The Indenture Trustee shall be entitled to withhold
from all payments of principal of (and premium, if any) and interest on this Security any amounts required to be withheld under the applicable
provisions of the Federal income tax laws of the United States at the time of such payments.

 

Prior to due presentment for registration of transfer
of this Security, the Company, the Indenture Trustee and any agent of the Company or the Indenture Trustee, may treat the Person in whose
name this Security is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes,
whether or not this Security be overdue and neither the Company, the Indenture Trustee nor any agent of the Company or Indenture Trustee
shall be affected by notice to the contrary.

 

If an Event of Default shall occur and be continuing,
the principal of the Securities of this series may be declared due and payable, and such declarations may be in certain events rescinded,
in the manner and with the effect provided in the Indenture.

 

The Indenture permits, to the extent therein provided,
the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected
under the Indenture at any time by the Company with the consent of the Holders of a majority in aggregate principal amount of the Securities
at the time Outstanding if all of the Securities Outstanding are affected, or the Holders of a majority in aggregate principal amount
of each series to be affected, in case one or more, but less than all, of the series of the Outstanding Securities are affected. The Indenture
also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series
at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions
of the Indenture and certain past defaults under the Indenture and the consequences thereof. Any such consent or waiver by the Holder
of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security or such other Security.

 

The Securities of this series are unsecured.

 

All terms in this Security which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

 

    iv 

     

    

 

No recourse shall be had for the payment of the
principal of (and premium, if any), or the interest, if any, on this Security, or for any claim based thereon, or upon any obligation,
covenant or agreement of the Company in the Indenture, against any partner, member, incorporator, stockholder, officer or director, as
such, past, present of future, of the Company or of any successor or any of their assets, whether by virtue of any constitution, statute
or rule of law or by the enforcement of any assessment of penalty or otherwise; and all such liability is expressly released and
waived as a condition of, and as part of the consideration for, the issuance of this Security.

 

This Security shall be governed by and construed
in accordance with the laws of The Commonwealth of Massachusetts.

Series will be determined, if such amounts may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index; 

(m) the provisions, if any, relating to any security provided for the Notes of the Series or the related Note Guarantees; 

(n) any addition to or change in the Events of Default which applies to any Notes of the Series and any change in the right of

 (r) whether the Notes of such Series are entitled to the benefits of the
Note Guarantee of any Guarantor pursuant to this Indenture; 
 (s) whether the terms and provisions set forth in Appendix A
of this Base Indenture apply to the Notes of such Series (and, unless so specified, such terms and provisions shall not apply to Notes of such Series); and 

(t) any other terms of the Notes of the Series (which may supplement, modify or delete any provision of this Indenture insofar
as it applies to such Series, regardless of whether this Indenture expressly contemplates such supplement, modification or deletion). 
 All
Notes of any one Series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture hereto or Officer’s
Certificate referred to above. 
 Section 2.03 Execution and Authentication. 

At least one Officer must sign the Notes for the Issuer by manual, facsimile or electronic (including PDF) signature. 

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be
valid. 
 A Note will not be valid until authenticated by the manual, facsimile or electronic (including PDF) signature of the Trustee. The
signature will be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee will at any time, and from
time to time, authenticate Notes for original issue in the principal amount provided in the Board Resolution, supplemental indenture hereto or Officer’s Certificate, upon receipt by the Trustee of a Company Order. Such Company Order may
authorize authentication and delivery pursuant to written instructions from the Issuer or its duly authorized agent or agents. Each Note will be dated the date of its authentication unless otherwise provided by a Board Resolution, a supplemental
indenture hereto or an Officer’s Certificate. 
 The aggregate principal amount of Notes of any Series outstanding at any time may not
exceed any limit upon the maximum principal amount for such Series set forth in the Board Resolution, supplemental indenture hereto or Officer’s Certificate delivered pursuant to Section 2.02, except as provided in Section 2.08. 

Prior to the issuance of Notes of any Series, the Trustee will have received: (a) the Board Resolution, supplemental indenture hereto or
Officer’s Certificate establishing the form and the terms of the Notes of that Series or of Notes within that Series, (b) an Officer’s Certificate complying with Section 12.04, and (c) an Opinion of Counsel complying with
Section 12.04. 

  
 -23- 

 The Trustee will have the right to decline to authenticate and deliver any Notes of such
Series if (a) the Trustee, being advised by counsel, determines that such action may not be taken lawfully or (b) a trust committee of directors and/or vice-presidents of the Trustee determines in good faith that such action would expose
the Trustee to personal liability to Holders of any then outstanding Series of Notes. 
 The Trustee may appoint an authenticating agent
acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such authenticating agent. An
authenticating agent has the same rights as an Agent to deal with Holders, the Issuer or an Affiliate of the Issuer. 
 Section 2.04 Registrar and
Paying Agent. 
 The Issuer will maintain, with respect to each Series of Notes, an office or agency where Notes of such Series may be
presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes of such Series may be presented for payment (“Paying Agent”). The Registrar will keep a register of each
Series of Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee will act as such. The Issuer or any of its Subsidiaries may act as Paying
Agent or Registrar. 
 If a Holder has given wire transfer instructions to the Issuer and the Issuer is the Paying Agent, the Issuer will
pay all principal, interest and premium, if any, on that Holder’s Notes in accordance with these instructions until given written notice to the contrary. All other payments on the Notes of any Series will be made at the Corporate Trust Office
of the Trustee, unless the Issuer elects to make interest payments by checks mailed to the Holders at their addresses in the books and records of the Registrar. 

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent and to act as custodian of any Global Note (or Global
Notes) with respect to each Series unless another Registrar or Paying Agent, as the case may be, is appointed prior to the time Notes of that Series are first issued. The Issuer may change the Paying Agent or Registrar with respect to the Notes of
any Series without prior notice to the Holders. 
 Section 2.05 Paying Agent to Hold Money in Trust. 

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders of any Series of Notes or the Trustee, all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest on such Series of Notes, and will notify the Trustee of any default by the Issuer in making any
such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it with respect to such series of Notes to the Trustee. The Issuer 

  
 -24- 

 
at any time may require a Paying Agent to pay all money held by it with respect to such series of Notes to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Issuer or a Subsidiary of the Issuer) will have no further liability for such money. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders of any Series
of Notes all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes. 

Section 2.06 Holder Lists. 
 The
Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of each Series of Notes and will otherwise comply with Trust Indenture Act § 312(a). If the
Trustee is not the Registrar, the Issuer will furnish to the Trustee at least ten 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 Holders of each Series of Notes. 
 Section 2.07 Transfer and Exchange. 

When Notes of a Series are presented to the Registrar or a co-registrar with a request to register a
transfer or to exchange them for an equal principal amount of Notes of the same Series of other denominations, the Registrar will register the transfer or make the exchange as requested if its requirements for such transactions are met. To permit
registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar’s request. A Holder may transfer or exchange Notes only in accordance with this Indenture. Upon any transfer or
exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly
permitted herein), but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon
exchanges pursuant to Sections 2.11, 3.06 or 9.05). 
 Neither the Issuer nor the Registrar will be required (a) to issue, register the
transfer or purchase of, or exchange Notes of any Series for the period beginning at the opening of business 15 days immediately preceding the sending of a notice of redemption of Notes of that Series selected for redemption and ending at the close
of business on the day such notice is sent or (b) to issue, register the transfer or purchase of, or exchange Notes of any Series selected for redemption. 

Section 2.08 Replacement Notes. 
 If
any mutilated Note is surrendered to the Trustee or the Issuer or the Trustee receives evidence to its satisfaction of the destruction, loss or theft and ownership of any Note, the Issuer will issue and the Trustee, upon receipt of a Company Order,
will authenticate and deliver a replacement Note of the same Series and of like tenor and principal amount in exchange and substitution for the mutilated Note, or in lieu and in substitution for the Note so destroyed, lost or stolen. In every case,
the applicant for a substituted Note shall furnish to the Issuer, the Trustee, and any authentication agent, such security or indemnity as may be required by them to indemnify them and save each of them harmless from any loss that any of them may
suffer if a Note is replaced, including an indemnity bond. The Issuer may charge for its expenses in replacing a Note. 

  
 -25- 

 Every replacement Note is an additional obligation of the Issuer and will be entitled to all
of the benefits of this Indenture equally and proportionately with all other Notes of such Series duly issued hereunder. 
 The provisions
of this Section 2.08 are exclusive and will preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

Section 2.09 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.09 as not outstanding. Except as set forth in Section 2.10 hereof, a
Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 
 If a Note is replaced pursuant to
Section 2.08 hereof, it ceases to be outstanding and shall be deemed cancelled for all purposes unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding, shall be deemed cancelled,
and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a
redemption or purchase date or at Maturity, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding, shall be deemed cancelled, and will cease to accrue interest. 

Section 2.10 Treasury Notes. 
 In
determining whether the Holders of the required principal amount of Notes of a Series have concurred in any request, demand, authorization, direction, notice, consent or waiver, Notes of a Series owned by the Issuer or any Guarantor, or by any
Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, shall be disregarded, except that (a) notwithstanding this Section 2.10, so long as all of the Notes of
a Series are owned by Deutsche Telekom or its Affiliates, Notes of such Series owned by Deutsche Telekom or its Affiliates shall not be disregarded for purposes of determining whether the Holders of the required principal amount of Notes of such
Series have concurred in any request, demand, authorization, direction, notice, consent or waiver and (b) for the purposes of determining whether the Trustee will be protected in relying on any such request, demand, authorization, direction,
notice, consent or waiver, only Notes of a Series that a Responsible Officer has been informed in writing are so owned will be so disregarded. 

  
 -26- 

 Section 2.11 Temporary Notes. 

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee will authenticate temporary Notes upon receipt of a
Company Order. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes, including any legend the Issuer deems appropriate. Without unreasonable delay,
the Issuer will prepare and the Trustee upon receipt of a Company Order will authenticate definitive Notes of the same Series and date of maturity in exchange for temporary Notes. Until so exchanged, temporary Notes will have the same rights under
this Indenture as the definitive Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 

Section 2.12 Cancellation. 
 The
Issuer or its agents or representatives at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, redemption,
purchase, cancellation, replacement or payment. The Trustee and no one else will promptly cancel all Notes surrendered for registration of transfer, exchange, redemption, purchase, payment, replacement or cancellation and will destroy canceled Notes
(subject to the record retention requirements of the Exchange Act). Certification of the cancellation and destruction of all canceled Notes will be delivered to the Issuer upon written request. The Issuer may not issue new Notes to replace Notes
that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.13 Persons Deemed Owners. 

The Issuer, the Trustee and any agent of the Issuer or the Trustee shall (subject to Section 2.15(e)) treat the Person in whose name such
Global Note is registered as the absolute owner of such Global Note for all purposes, including for the purpose of receiving payment of principal of, and any premium and any interest, if any, on, such Global Note and for all other purposes
whatsoever, whether or not such Global Note be overdue, and neither the Issuer nor Trustee nor any of their respective agents shall be affected by notice to the contrary. 

Neither the Issuer, nor the Trustee, nor any of their respective agents will have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Section 2.14 Defaulted Interest. 

If the Issuer defaults in a payment of interest on a Series of Notes, it will pay the defaulted interest in any lawful manner, plus, to
the extent lawful, any interest payable on the defaulted interest, to the Persons who are Holders of the Notes of such Series on a subsequent special record date. The Issuer will fix such special record date and payment date. At least 10 days before
such special record date, the Issuer will send to the Trustee and to each Holder of Notes of the applicable Series a notice that states the record date, the payment date and the amount of interest to be paid. The Issuer may pay defaulted interest in
any other lawful manner. 

  
 -27- 

 Section 2.15 Global Notes. 

(a) Terms of Notes. A Board Resolution, a supplemental indenture hereto or an Officer’s Certificate will establish
whether the Notes of a Series will be issued in whole or in part in the form of one or more Global Notes and the Depositary, if any, for such Global Note or Notes. 

(b) Legend. Any Global Note issued hereunder will bear a legend in substantially the following form: 

“THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR
A NOMINEE OF THE DEPOSITARY. THIS NOTE IS EXCHANGEABLE FOR NOTES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE
BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY, BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH A SUCCESSOR
DEPOSITARY.” 
 (c) Acts of Holders. The Depositary, as a Holder, may appoint agents and otherwise authorize
participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Indenture. 

(d) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by
Section 2.02, payment of the principal of and premium, if any and interest, if any, on any Global Note will be made to the Holder thereof. 

(e) Rights of Beneficial Owners. No beneficial owner of a beneficial interest in any Global Note held on its behalf by a
Depositary shall have any rights under this Indenture with respect to such Global Note, and such Depositary shall be treated by the Issuer, the Trustee, and any agent of the Issuer or the Trustee as the sole beneficial owner of such Note for all
purposes whatsoever. 
 Section 2.16 CUSIP, ISIN and Common Code Numbers. 

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

 ARTICLE III 

REDEMPTION

Notes or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in the Board Resolution, Officer’s Certificate or supplemental indenture relating to such Series. If a Series of Notes is redeemable
and the Issuer wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Notes pursuant to the terms of such Notes, it must furnish to the Trustee, at least 10 days (or such shorter period as may be permitted
by the Trustee) but not more than 60 days before a redemption date, an Officer’s Certificate setting forth: 
 (1) the
redemption date; 
 (2) the principal amount of Notes of a Series to be redeemed; and 

(3) the redemption price. 

Section 3.02 Selection of Notes to be Redeemed. 

Unless otherwise indicated for a particular Series in the Board Resolution, Officer’s Certificate or supplemental indenture under which
such Series of Notes is issued or in the form of Note for such Series, if less than all of the Notes of a Series are to be redeemed at any time, the Registrar will select or cause to be selected the Notes of such Series to be redeemed on a pro
rata or by lot basis unless otherwise required by law or applicable stock exchange or Depositary requirements. In the event of partial redemption by lot, the particular Notes of a Series to be redeemed will be selected, unless otherwise provided
herein, not less than 10 days (or such shorter period as may be permitted by the Trustee) but not more than 60 days prior to the redemption date by the Trustee from the outstanding Notes of such Series not previously called for redemption. 

The Trustee will promptly notify the Issuer in writing of the Notes of a Series selected for redemption and, in the case of any Note of such
Series selected for partial redemption, the principal amount thereof to be redeemed. Notes of a Series and portions of Notes of a Series selected will be in minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof or, with
respect to Notes of any Series issuable in other denominations pursuant to Section 2.02(i), the minimum principal denomination for each Series and integral multiples thereof; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes of such Series held by such Holder, even if not in compliance with the foregoing, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes of a Series called
for redemption also apply to portions of Notes of that Series called for redemption. 

  
 -29- 

 Section 3.03 Notice of Redemption. 

Unless otherwise indicated for a particular Series in the Board Resolution, Officer’s Certificate or supplemental indenture under which
such Series of Notes is issued or in the form of Note for such Series, at least 10 days but not more than 60 days before a redemption date, the Issuer will send electronically, or mail by first-class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address, except that redemption notices may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes of a Series or a satisfaction
and discharge of the Notes of any Series pursuant to ARTICLES VIII or XI hereof. 
 The notice will identify the Notes to be
redeemed and will state: 
 (1) the redemption date and whether the redemption is conditioned on any transaction or event;

 (2) the redemption price; 

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the
redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 

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

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

 (6) that, unless the Issuer defaults in making such redemption payment, interest on Notes of the Series called for
redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the Notes called for redemption are being redeemed; 
 (8) the CUSIP, ISIN and/or Common Code
number, if any; 
 (9) that no representation is made as to the correctness or accuracy of the CUSIP, ISIN and/or Common Code
number, if any, listed in such notice or printed on the Notes; and 
 (10) any other information as may be required by the
terms of the particular Series or the Notes of the Series being redeemed. 
 At the Issuer’s request, the Trustee will give the notice
of redemption in the Issuer’s name and at its expense, provided, that the Issuer makes such request no later than 1:00 p.m., New York City time, on the date that is at least five Business Days (or such shorter period as may be permitted
by the Trustee) prior to the date by which such notice must be given to Holders in accordance with this Section 3.03. 

  
 -30- 

 Section 3.04 Effect of Notice of Redemption. 

Except to the extent that a notice of redemption is conditional as permitted by this Indenture, once notice of redemption is sent in
accordance with Section 3.03 hereof, Notes of a Series called for redemption become due and payable on the redemption date at the redemption price. On and after the redemption date, interest ceases to accrue on Notes or portions of Notes called
for redemption. 
 Section 3.05 Deposit of Redemption Price. 

On or before 10:00 a.m., New York City time, on the redemption date (or such other time as specified in the Supplemental Indenture with
respect to any Series of Notes), the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying
Agent will promptly, but in any event no later than 1:00 p.m., New York City time on the next succeeding Business Day, return to the Issuer any money so deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary
to pay the redemption price of, and accrued interest, if any, on, all Notes to be redeemed, or if any condition to the redemption is not satisfied. The Trustee will not be liable or responsible for any interest on the funds deposited. 

If the Issuer 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 Issuer 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 Issuer will issue and, upon receipt of a Company Order, the Trustee will authenticate
for the Holder at the expense of the Issuer a new Note of the same Series and in equal principal amount to the unredeemed portion of the Note surrendered. 

ARTICLE IV 
 COVENANTS 

Section 4.01 Payment of Notes. 
 The
Issuer will pay or cause to be paid the principal of, and premium, if any, and interest on the Notes of each Series on the dates and in the manner provided in the Notes of such Series. Principal, premium, if any, and interest will be considered paid
on the date due if the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds on or before 12:00 noon, New York City time, on the due date money deposited by the Issuer in immediately available funds and designated for and sufficient
to pay all principal, premium, if any, and interest then due.

 Section 4.02 Maintenance of Office or Agency. 

The Issuer will maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and
this Indenture may be served. The Issuer will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer fails to maintain any such required office or agency or
fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuer of its obligation to maintain an office or agency in the Borough
of Manhattan, the City of New York for such purposes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with
Section 2.04 hereof. 
 Section 4.03 Reports. 

Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, Parent will file a copy of each of the
Parent reports referred to in clauses (1) and (2) below with the SEC for public availability within the time periods (including all applicable extension periods) specified in the SEC rules and regulations applicable to such reports (unless
the SEC will not accept such a filing): 
 (1) all quarterly and annual financial reports that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if Parent were required to file such reports, including a “Management’s Discussion and Analysis
of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by its certified independent accountants; and 

(2) all current reports that would be required to be filed with the SEC on
Form 8-K if Parent were required to file such reports; 

  
 -32- 

 provided that the availability of the foregoing reports on the SEC’s EDGAR service (or successor
thereto) shall be deemed to satisfy the Issuer’s delivery obligations to the Trustee and any Holder of Notes. 
 All such reports will
be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports; provided that, if Parent is not required under the rules and regulations of the SEC to file such reports with the SEC for
public availability, such reports need not be prepared in accordance with all of the rules and regulations applicable to such reports and shall only be required to include the information or disclosure that would be required by such form to the
extent that, and in the same general style of presentation as, the same or substantially similar information or disclosure is also included or incorporated by reference in the offering memorandum, prospectus or prospectus supplement pursuant to
which the applicable Notes were offered and sold. The Issuer will comply with Trust Indenture Act §314(a). 
 If the SEC will not
accept Parent’s filings for any reason, the Issuer will post the reports referred to in the preceding paragraphs on its website, on intralinks.com or another website within the time periods that would apply if Parent were required to file those
reports with the SEC (including all applicable extension periods). 
 Notwithstanding anything herein to the contrary, the Issuer will not
be deemed to have failed to comply with any of its obligations hereunder for purposes of Section 6.01(4) until 150 days after the receipt of the written notice delivered thereunder. 

For so long as any Notes remain outstanding, if at any time Parent is not required to file with the SEC the reports required by paragraphs
(a) and (b) of this Section 4.03, Parent will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities
Act. 
 Delivery of such reports, information and documents to the Trustee shall be considered for informational purposes only, and the
Trustee’s receipt of such reports shall not constitute notice or actual knowledge of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). 
 Section 4.04 Compliance Certificate.

 The Issuer and each Guarantor shall deliver to the Trustee, in compliance with Trust Indenture Act § 314(a)(4), within 120 days
after the end of each fiscal year, an Officer’s Certificate stating that a review of the activities of the Issuer and the Guarantors during the preceding fiscal year has been made under the supervision of the signing Officers with a view to
determining whether the Issuer and each Guarantor has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to his or her knowledge the Issuer and
each Guarantor has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default
or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge). 

  
 -33- 

 So long as any of the Notes are outstanding, the Issuer will deliver to the Trustee, within
30 days after becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto unless such Default or Event of
Default has been cured or waived in such period. 
 Section 4.05 Stay, Extension and Usury Laws. 

Each of the Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture or the Notes;
and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.06 Liens. 

(a) The Issuer will not, and will not permit any Material Subsidiary to, directly or indirectly, create, incur or assume any
Lien securing Indebtedness for Borrowed Money upon any of its or any Material Subsidiary’s Principal Property or upon Capital Stock or Indebtedness of any Material Subsidiary that directly owns any Principal Property, except Permitted Liens,
unless the Notes are equally and ratably secured with (or, at the Issuer’s option, on a senior basis to) the Indebtedness for Borrowed Money so secured. 

(b) Any Lien created for the benefit of the Holders of the Notes pursuant to Section 4.06(a) shall provide by its terms
that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to such Lien created for the benefit of the Holders of the Notes. 

(c) For purposes of determining compliance with this Section 4.06, (x) a Lien need not be incurred solely by reference to
one category of Permitted Liens, but may be incurred under any combination of such categories (including in part under one such category and in part under any other such category) and (y) in the event that a Lien (or any portion thereof) meets
the criteria of one or more of such categories of Permitted Liens, the Issuer shall, in its sole discretion, divide, classify or may subsequently reclassify at any time such Lien (or any portion thereof) in any manner that complies with this
Section 4.06 and the definition of “Permitted Liens.”

 DEFAULTS AND REMEDIES 
 Section 6.01
Events of Default. 
 Each of the following is an “Event of Default” in respect of the Notes of any Series, unless

 (5) default under any mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the Issuer or any of its Significant Subsidiaries (or any of its Subsidiaries that together would constitute a Significant Subsidiary) (or the payment of which Indebtedness for
borrowed money is guaranteed by the Issuer or any of its Significant Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default: 

(A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness at the later of final
maturity and the expiration of any related applicable grace period (a “Payment Default”); or 

  
 -36- 

 (B) results in the acceleration of such Indebtedness prior to its express
maturity; 
 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, aggregates an amount equal to the greater of $1,500.0 million and 0.675% of Consolidated Total Assets of Parent determined on a pro
forma basis for acquisitions, dispositions and Pro Forma Transactions or more, in each case for so long as such failure or acceleration is continuing;

determined on a pro forma basis for acquisitions, dispositions and Pro Forma Transactions (to the extent not covered by indemnities or insurance), which judgments are not paid, discharged or stayed for a period of 60 consecutive days following entry
of such final judgment or decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, is not in effect;

 (8) a court of competent jurisdiction enters a final order or decree under
any Bankruptcy Law that:

Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer in an involuntary case; 

(B) appoints a custodian of the Issuer or any of its Significant Subsidiaries or any group of Subsidiaries of the Issuer that,
taken together, would constitute a Significant Subsidiary of the Issuer or for all or substantially all of the property of the Issuer or any of its Significant Subsidiaries or any group of Subsidiaries of the Issuer that, taken together, would
constitute a Significant Subsidiary; or 
 (C) orders the liquidation of the Issuer or any of its Significant Subsidiaries
or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer;

 (9) except as permitted by this Indenture,
(a) any Note Guarantee of a Significant Subsidiary or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer with respect to Notes of such Series (i) is held in any judicial
proceeding to be unenforceable or invalid or (ii) ceases for any reason to be in full force and effect, or (b) any Guarantor, or any Person acting on behalf of any such Guarantor, denies or disaffirms its obligations under its Note
Guarantee. 
 A Default under one Series of Notes issued under this Indenture will not necessarily be a Default under another Series of
Notes issued under this Indenture. 
 Section 6.02 Acceleration. 

In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Issuer, any of
its Significant Subsidiaries or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer, all outstanding Notes of such Series will become due and payable immediately without further
action or notice. If any other Event of Default occurs and is continuing with respect to any Series of Notes, the Trustee or the Holders, with a copy to the Trustee, of at least 30% in aggregate principal amount of the then outstanding Notes of such
Series may declare all the Notes of such Series to be due and payable immediately; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two
years prior to such declaration. 

  
 -38- 

 The Holders of a majority in aggregate principal amount of the then outstanding Notes of
such Series by written notice to the Trustee may, on behalf of all Holders of Notes of that Series, rescind an acceleration or waive any existing Default or Event of Default in respect of such Series of Notes and its consequences under this
Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes of such Series. 

Section 6.03 Other Remedies. 
 If an
Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes of a Series or to enforce the performance of any provision of the Notes of such
Series or this Indenture. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, the Guarantors, the
Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders will continue as though no such proceeding had been instituted. 

The Trustee may maintain a proceeding with respect to the Notes of any Series even if it does not possess any of the Notes of such Series or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note of any Series in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver
of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 The Trustee may withhold from
holders of the 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 in the payment of the principal of, or the interest or premium, if any, on
the Notes of such Series. 
 Section 6.04 Waiver of Past Defaults. 

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes of any Series by notice to the Trustee may on
behalf of the Holders of all of the Notes of such Series waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the
principal of, the Notes of such Series. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 

The Holders of a majority in aggregate principal amount of the then outstanding Notes of any Series may direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Notes of such Series. However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of the Notes of such Series or that may involve the Trustee in personal liability. 

  
 -39- 

 Section 6.06 Limitation on Suits. 

Except to enforce the right to receive payment of principal, premium (if any) or interest when due, a Holder may pursue a remedy with respect
to this Indenture or the Notes of any Series only if: 
 (1) such Holder gives to the Trustee written notice that an Event of
Default for such Series of Notes is continuing; 
 (2) Holders of at least 30% in aggregate principal amount of the then
outstanding Notes of the applicable Series have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(3) such Holder or Holders offer and, if requested, provide to the Trustee indemnity or security satisfactory to the Trustee
against any loss, liability or expense to be incurred in compliance with such request; 
 (4) the Trustee does not comply
with the request within 90 days after receipt of the request and the offer of indemnity or security; and 
 (5) during such 90-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes of such Series do not give the Trustee a direction inconsistent with such request. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note of the same Series or to obtain a preference
or priority over another Holder of a Note of the same Series. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if
any, and interest on the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such
Holder. 
 Section 6.08 Collection Suit by Trustee. 

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

  
 -40- 

 Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable and actual out-of-pocket expenses and disbursements of the Trustee) and the Holders of the Notes allowed in
any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable and actual out-of-pocket expenses and disbursements of the Trustee, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such amounts due the Trustee, its agents and outside counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether
in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities. 
 If the
Trustee collects any money pursuant to this ARTICLE VI on account of a Series of Notes, it shall pay out the money in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of
principal or interest, upon presentation of the Notes of such Series and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

First: To the payment of all amounts due the Trustee and each Agent under Section 7.07; 

Second: To the payment of the amounts due and unpaid for principal of, premium, if any, and interest on the Notes of such
Series in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes of such Series for principal, premium, if any and
interest, respectively; and 
 Third: To the Issuer or the Guarantors, as applicable. 

  
 -41- 

 Section 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of such suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the outstanding Notes of any Series, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or interest on any Note on or after the Stated Maturity or Stated Maturities expressed in such Note (or, in the case of redemption, on the redemption date). 

ARTICLE VII 
 TRUSTEE 

Section 7.01 Duties of Trustee. 

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which
may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred and is continuing with respect to any Series of Notes, the Trustee will exercise such of
the rights and powers vested in it by this Indenture in respect of such Series of Notes, 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 with respect to the Notes of any
Series: 
 (1) the Trustee and the Agents shall not be liable except for the performance of such duties as are specifically
set out in this Indenture and no implied duties or obligations shall be read into this Indenture against the Trustee and the Agents (it being agreed that a permissive right of the Trustee and the Agents shall not be construed as a duty); and 

(2) in the absence of bad faith on its part, the Trustee and the Agents may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel furnished to the Trustee and the Agents and conforming to the requirements of this Indenture; however, in the case of
any such Officer’s Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee and the Agents, the Trustee and the Agents will examine such Officer’s Certificates and Opinions
of Counsel to determine whether or not they conform on their face to the requirements of this Indenture, but need not confirm or investigate the accuracy of statements, calculations or other facts stated therein. 

  
 -42- 

 (c) The Trustee and the Agents may not be relieved from liabilities for its
own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph
does not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee and the Agents will not be
liable for and shall be protected pursuant to the indemnification provisions in Section 7.07 hereof from, any error of judgment made in good faith by a Responsible Officer of the Trustee, unless it shall be proved that the Trustee or Agent was
negligent in ascertaining the pertinent facts; and 
 (3) the Trustee and the Agents will not be liable for and shall be
protected pursuant to the indemnification provisions in Section 7.07 hereof from, any action it takes or omits to take with respect to Notes of any Series in good faith in accordance with the direction of the Holders of a majority in principal
amount of the outstanding Notes of such Series pursuant to Section 6.05 hereof. 
 (d) Whether or not therein expressly
so provided, every provision of this Indenture that in any way relates to the Trustee and the Agents is subject to paragraphs (a), (b), and (c) of this Section 7.01. 

(e) No provision of this Indenture will require the Trustee or any Agent to expend or risk its own funds or incur any
liability, financially or otherwise. The Trustee and any Agent will be under no obligation to exercise any of its rights or powers under this Indenture or the Notes Documents at the request of any Holder, unless such Holder has offered to the
Trustee or applicable Agent security and indemnity satisfactory to it against any loss, liability or expense. 
 (f) The
Trustee and the Agents will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required
by law. 
 Section 7.02 Rights of Trustee and the Agents. 

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by
the proper Person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts
or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion
of Counsel or both. The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon. 

  
 -43- 

 (c) The Trustee may act through its attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due care. 
 (d) The Trustee will not be liable for
any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. 

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer will be
sufficient if signed by an Officer of the Issuer. 
 (f) The Trustee will be under no obligation to exercise any of the
rights or powers vested in it by this Indenture or the Notes Documents at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and
expenses that might be incurred by it in compliance with such request or direction. 
 (g) The Trustee shall not be deemed to
have notice of any Default or Event of Default, except a Default under Sections 6.01(1) or 6.01(2), unless written notice of any event which is in fact such a Default or Event of Default is received by a Responsible Officer at Corporate Trust Office
of the Trustee from either of the Issuer or the Holders of 30% in aggregate principal amount of the outstanding Notes of the relevant Series, and such notice references the specific Default or Event of Default, the Notes and this Indenture and, in
the absence of any such notice, the Trustee may conclusively assume that no such Default or Event of Default exists. 
 (h)
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. 
 (i) The rights, privileges, protections,
immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee (i) in each of its capacities hereunder, including, without limitation, as each Agent, custodian and
other Person employed to act hereunder and (ii) in each document related hereto to which it is a party. 
 (j) The
Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 

(k) The Trustee may request that the Issuer 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. 

  
 -44- 

 (l) [reserved]. 

(m) If the Trustee requests instructions from the Issuer or the Holders with respect to any action or omission in connection
with the Indenture, the Trustee shall be entitled (without incurring any liability therefor) to refrain from taking such action and continue to refrain from acting unless and until the Trustee shall have received written instructions from the Issuer
or the Holders, as applicable, with respect to such request. 
 (n) The Trustee shall not be liable for failing to comply
with its obligations under the Indenture in so far as the performance of such obligations is dependent upon the timely receipt of instructions and/or other information from any other person which are not received or not received by the time
required. 
 (o) The Trustee and the Agents shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document, but the Trustee and the Agents may (but shall not be obligated to) make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee or an Agents shall determine to make such further inquiry or investigation, they shall be entitled to examine the books, records and premises of the Issuer,
personally or by agent or attorney, at the expense of the Issuer and shall incur no liability of any kind by reason of such inquiry or investigation. 

Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest when a Default is continuing it must eliminate such conflict within 90 days of the date such
conflict arises, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the Trust Indenture Act) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections
7.10 and 7.11 hereof. 
 Section 7.04 Trustee’s Disclaimer. 

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

 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing with respect to the Notes of any Series and if it is actually known to a Responsible
Officer of the Trustee, the Trustee shall send to each Holder of the Notes of that Series notice of the Default or Event of Default within 120 days after the occurrence thereof; provided, that except in the case of default in the payment of
principal of, or the interest or premium, if any, on any Note of any Series, the Trustee shall be protected pursuant to the indemnification provisions in Section 7.07 hereof in withholding such notice if and so long as a committee of its
Responsible Officers in good faith determines that the withholding of such notice is in the interests of Holders of that Series. 
 Section 7.06
Reports by Trustee to Holders of the Notes. 
 (a) Within 60 days after May 15 in each year, the Trustee will

on any stock exchange. 
 Section 7.07 Compensation and Indemnity. 

(a) The Issuer will pay to the Trustee and the Agents from time to time
compensation for its acceptance of this Indenture and services hereunder, as separately agreed in writing. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer will further
reimburse the Trustee promptly upon request for all reasonable and actual out-of-pocket disbursements and expenses incurred in accordance with any of the provisions
hereof or any other document executed in connection herewith. Such expenses will include the reasonable and actual disbursements and expenses of the Trustee’s agents and outside counsel.

liabilities or expenses incurred by it arising out of or in connection with the acceptance and administration of its duties under this Indenture, including the reasonable and actual costs and expenses of enforcing this Indenture against the Issuer
and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its
powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its gross negligence or willful misconduct. The Trustee will notify the Issuer promptly of any claim for which it may seek indemnity;
provided that the failure by the Trustee to deliver such notice shall not relieve the Issuer of its obligations hereunder. The Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have
one separate counsel and one local counsel in each jurisdiction (as applicable) and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its consent. 

  
 -46- 

 (c) The obligations of the Issuer and the Guarantors under this
Section 7.07 will survive the satisfaction and discharge of this Indenture as to any Series of Notes or the removal or resignation of the Trustee or any Agent. 

(d) To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a
Lien prior to the Notes of any Series on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes of that Series. Such Lien will survive the satisfaction or discharge of this
Indenture as to any Series of Notes. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default
specified in Section 6.01(7) or (8) 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. 
 (f) The Trustee will comply with the provisions of Trust Indenture Act § 313(b)(2) to the extent applicable.

 Section 7.08 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 7.08. 
 (b) The Trustee may resign with
respect to the Notes of one or more Series in writing at any time and be discharged from the trust hereby created by so notifying the Issuer at least 30 days prior to the effective date of such resignation. The Holders of a majority in aggregate
principal amount of the then outstanding Notes of any Series may remove the Trustee with respect to that Series by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee with respect to the Notes of one or more Series
if: 
 (1) the Trustee fails to comply with Section 7.10 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 for any reason, with respect to the
Notes of one or more Series, the Issuer will promptly appoint a successor Trustee with respect to the Notes of that Series. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then
outstanding Notes of such Series may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 

  
 -47- 

 (d) If a successor Trustee with respect to the Notes of any one or more
Series does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer, or the Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such Series may
petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (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 7.10 hereof, such Holder may petition 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
Issuer. 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 Notes for which it is acting as Trustee
under this Indenture. The successor Trustee will mail a notice of its succession to each Holder of each such Series. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided that all
sums owing to the Trustee hereunder have been paid and subject to the lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07
hereof will continue for the benefit of the retiring Trustee with respect to the expenses, liabilities and indemnities incurred by it prior to such replacement. 

Section 7.09 Successor Trustee by Merger, etc. 

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
entity, the successor entity without any further act will be the successor Trustee. 
 Section 7.10 Eligibility; Disqualification.

America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100.0 million as set forth in its most recent published annual report of condition. This Indenture will always have a Trustee who satisfies the requirements of Trust Indenture Act § 310(a)(1), (2) and (5). The Trustee is subject to
Trust Indenture Act § 310(b). 
 Section 7.11 Preferential Collection of Claims Against Issuer.

 -48- 

 Section 7.12 Force Majeure. 

In no event shall the Trustee or the Agents be responsible or liable for any failure or delay in the performance of their obligations
hereunder arising out of or caused by, directly or indirectly, forces that are not foreseen and which are beyond their control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or
natural catastrophes or acts of God, and interruptions, epidemics and pandemics, loss or malfunctions of utilities, loss of wire or other communication facilities; it being understood that the Trustee and the Agents shall use reasonable efforts

ARTICLE VIII 
 LEGAL DEFEASANCE AND
COVENANT DEFEASANCE 
 Section 8.01 Legal Defeasance and Covenant Defeasance. 

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

Section 8.02 Legal Defeasance and Discharge. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the
Guarantors will, with respect to Notes of any Series, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes of such Series
(including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes of such Series (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the
Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 

(1) the rights of Holders of outstanding Notes of such Series to receive payments in respect of the principal of, or interest
or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 
 (2)
the Issuer’s obligations with respect to such Notes under ARTICLE II and Section 4.02 hereof; 

  
 -49- 

 (3) the rights, powers, trusts, duties, indemnities and immunities of the
Trustee hereunder, and the Issuer’s and the Guarantors’ obligations in connection therewith; and 
 (4) the
provisions of this ARTICLE VIII. 
 Subject to compliance with this ARTICLE VIII, the Issuer may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of the
Guarantors will, with respect to Notes of any Series and subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04, 4.05 and
4.06 hereof with respect to the outstanding Notes of such Series on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes of such Series will
thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed
“outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes of a
Series and related Note Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply 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 Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’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 Section 8.04 hereof, Sections 6.01(3) through 6.01(9) (in the case of Sections 6.01(7) and 6.01(8), only with respect to the Issuer’s
Subsidiaries) and Section 6.01(10) hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant
Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof with
respect to Notes of any Series: 
 (1) the Issuer must irrevocably deposit with the Trustee or its designee, in trust, for
the benefit of the Holders of such Series, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such 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, and premium, if any, and interest on, the outstanding Notes of such Series on the stated date for payment thereof or on the applicable redemption
date, as the case may be, and the Issuer must specify whether the Notes of such Series are being 

  
 -50- 

 
defeased to such stated date for payment or to a particular redemption date; provided that in connection with any Legal Defeasance or Covenant Defeasance that requires the payment of a premium,
the amount deposited shall be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to premium calculated as of the date of the deposit, with any deficit as of the maturity date of the Notes of
such Series only required to be deposited with the Trustee on or prior to the maturity date of the Notes of such Series; 

(2) in the case of an election under Section 8.02 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel
confirming that: 
 (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling;
or 
 (B) since the date Notes of such Series were first issued, there has been a change in the applicable U.S. federal
income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the beneficial owners of
the outstanding Notes of such Series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not occurred; 
 (3) in the case of an election under
Section 8.03 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel confirming that the beneficial owners of the outstanding Notes of such Series will not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Event of Default has occurred and is continuing with respect to the Notes of the applicable Series on the date of such
deposit (other than an Event of Default resulting from the borrowing of funds, or the imposition of Liens in connection therewith, to be applied to such deposit, or an Event of Default that will be cured by such Covenant Defeasance or Legal
Defeasance) and the deposit will not otherwise result in a breach or violation of, or constitute a default under, any material instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound; 

(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 Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound; 

(6) the Issuer must deliver to the Trustee an Officer’s Certificate, stating that the deposit was not made by the Issuer
with the intent of preferring the Holders over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or others; 

  
 -51- 

 (7) the Issuer must deliver to the Trustee an Officer’s Certificate,
stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and 

(8) the Issuer must deliver to the Trustee an Opinion of Counsel, stating that all conditions precedent set forth in clauses
(2) and (3) of this Section 8.04, as applicable, 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 of a Series will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Issuer 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 of, and premium, if any, and interest but such money need not be
segregated from other funds except to the extent required by law. 
 The Issuer will 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 of such Series. 
 Notwithstanding
anything in this ARTICLE VIII to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the written request of the Issuer 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 investment bank, appraisal firm, or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be
the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. This provision shall not authorize the sale by
the Trustee of any Government Securities held under this Indenture. 
 Section 8.06 Repayment to Issuer. 

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

  
 -52- 

 Section 8.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government
Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and the
Guarantors’ obligations under this Indenture with respect to the Notes of such Series and under the Notes of such Series and the corresponding Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer makes
any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Issuer will 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 IX

Notwithstanding Section 9.02 hereof, the Issuer, the Guarantors of the Notes of any Series and the Trustee may amend or supplement this
Indenture with respect to such Series, the Notes of such Series or the related Note Guarantees without the consent of any Holder of Notes: 

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

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(7) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust
Indenture Act; 
 (8) to change or eliminate any of the provisions of this Indenture with respect to such Series,
provided that any such change or elimination shall not become effective with respect to any outstanding Notes of any Series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision; 

(9) to provide for the issuance of and establish forms and terms and conditions of a new Series of Notes as permitted by this
Indenture; 
 (10) to conform the text of this Indenture, any Notes or any related Note Guarantees to the description of the

Officer’s Certificate; 
 (11) to provide for the issuance of Additional Notes of any Series, provided that such

(12) to evidence and provide for the acceptance of and appointment by a successor trustee or collateral trustee with respect to
the Notes of such Series and to add to or change any of the provisions of this Indenture with respect to such Series as shall be necessary to provide for or facilitate the administration of the trust by more than one trustee; 

(13) to allow any Guarantor of the Notes of such Series to execute a supplemental indenture providing a Note Guarantee with

 Upon the written request of the Issuer accompanied by a resolution of its Board of

Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be
obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

  
 -54- 

 Section 9.02 With Consent of Holders of Notes. 

Except as provided below in this Section 9.02, the Issuer, the Guarantors of the Notes of any Series and the Trustee may amend or
supplement this Indenture with respect to the Notes of such Series, or the Notes of such Series, or the related Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the Notes of such Series then
outstanding (including consents obtained in connection with a purchase of, or a tender offer or exchange offer for, Notes of such Series), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default with respect to the
Notes of such Series or compliance with any provision of this Indenture or the Notes of such Series or the related Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the Notes of such Series
then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes of such Series). Section 2.09 and 2.10 hereof shall determine which Notes are considered to be “outstanding”
for purposes of this Section 9.02. 
 Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing
the execution of any such amended or supplemental indenture and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes of a Series as aforesaid, and upon receipt by the Trustee of the
documents described in Section 7.02 hereof, the Trustee shall join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may, but will not be obligated to, enter into such amended or supplemental indenture. 

However, without the consent of each Holder of Notes of the applicable Series affected, an amendment, supplement or waiver (including a waiver
pursuant to Section 6.04) under this Section 9.02 may not (with respect to any Notes of any Series held by a non-consenting Holder): 

(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 Note of such Series or alter the provisions with respect to the
redemption of the Notes of such Series (except with respect to notice periods for redemption); 
 (3) reduce the rate of or
change the time for payment of interest on any Note of such Series; 
 (4) waive a Default or Event of Default in the payment
of principal of, or premium, if any, or interest on, the Notes of such Series (except a rescission of acceleration of the Notes of such Series by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such
Series and a waiver of the payment default that resulted from such acceleration); 
 (5) make any Note of such Series payable
in money other than that stated in the Notes; 

  
 -55- 

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

(7) waive a redemption payment with respect to any Note of such Series; 

(8) release any Guarantor from any of its obligations under its Note Guarantee of the Notes of such Series or this Indenture
with respect to such Series, except in accordance with the terms of this Indenture; or 
 (9) make any change in the
preceding amendment and waiver provisions. 
 It is not necessary for the consent of the Holders of Notes of a Series 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. 

For the avoidance of doubt, any amendment, supplement or waiver to any Series of Notes made with the consent of Holders of such Series of
Notes, shall be made with respect to that Series of Notes only, and not any other Series of Notes, unless the Holders of such other Series of Notes consent to such amendment, supplement or waiver to such other Series of Notes. 

For the avoidance of doubt, no amendment to, or deletion of any of the covenants under ARTICLE IV, or action taken in compliance with the
covenants in effect at the time of such action, shall be deemed to impair or affect any legal rights of any Holders of any Series of Notes to receive payment of principal of or premium, if any, or interest on the Notes of such Series or to institute
suit for the enforcement of any payment on or with respect to such Holders’ Notes of any Series. 
 After an amendment, supplement or
waiver under this Section 9.02 becomes effective, the Issuer will send or cause to be sent to the Holders of Notes of a Series affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to send
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 Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal
amount of the Notes of a Series then outstanding may waive compliance in a particular instance by the Issuer with any provision of this Indenture with respect to such Series or the Notes of such Series or the related Note Guarantees. 

Section 9.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes of one or more Series will be set forth in a Board Resolution, Officer’s
Certificate, or amended or supplemental indenture that complies with the Trust Indenture Act as then in effect, to the extent the Trust Indenture Act is then applicable hereto. 

  
 -56- 

 Section 9.04 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before 11:59 p.m. New York City Time on the Business Day immediately prior to 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 of each Series affected. 

Section 9.05 Notation on or Exchange of Notes. 

The Issuer may place an appropriate notation about an amendment, supplement or waiver on any Note of any Series thereafter authenticated. The
Issuer in exchange for Notes of that Series may issue and the Trustee shall, upon receipt of a Company Order, authenticate new Notes of that Series 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 9.06 Trustee to Sign Amendments, etc. 

The Trustee will sign any amended or supplemental indenture authorized pursuant to this ARTICLE IX if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors of the Issuer approves it. In executing any amended or supplemental indenture,
the Trustee will be entitled to receive and will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such
amended or supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent with respect thereto have been satisfied. 

ARTICLE X 
 NOTE GUARANTEES 

Section 10.01 Note Guarantees. 

(a) Notwithstanding any provision of this ARTICLE X to the contrary, the provisions of this ARTICLE X will be applicable only
to, and inure solely to the benefit of, the Notes of any Series designated, pursuant to Section 2.02(r), as entitled to the benefits of the Note Guarantee of each Guarantor identified in such designation. 

  
 -57- 

 (b) Subject to this ARTICLE X, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to the Holders of each Series of Notes authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes
or the obligations of the Issuer hereunder or thereunder, that: 
 (1) the principal of, premium, if any, and interest on the
Notes of such Series will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on such Notes, if any, if lawful, and all other obligations of
the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

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

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and
severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(a) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance
of the obligations contained in the Notes and this Indenture. 
 (b) If any Holder or the Trustee is required by any court or
otherwise to return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note
Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (c) Each 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 Guarantor further agrees that, as between the
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 VI hereof for the purposes of this Note 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 VI hereof, such
obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

 Section 10.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to
any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such 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 Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under this ARTICLE X, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. 

Section 10.03 Execution and Delivery. 

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor shall execute the supplemental indenture substantially
in the form set forth in Exhibit A or such other supplemental indenture to this Indenture (including substantially in the form of the supplemental indenture set forth in Exhibit A). Upon the execution and delivery of such supplemental indenture,
each Guarantor who executes such supplemental indenture agrees that its Note Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the
Notes. 
 If an Officer whose signature is on such a supplemental indenture to this Indenture no longer holds that office at the time the
Trustee authenticates the Note, the Note Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee, after the
authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. 

Section 10.04 Releases. 

(a) The Note Guarantee of a Guarantor will be automatically and unconditionally released in respect of the Notes of any Series:

 (1) only in the case of a Subsidiary Guarantor, at such time as such Subsidiary Guarantor (i) is not, (ii) is
released or relieved as, or (iii) ceases (or substantially concurrently will cease) to be, a borrower or guarantor under the Credit Agreement, except by or as a result of payment under such guarantee or direct obligation; 

  
 -59- 

 (2) only in the case of a Subsidiary Guarantor, in connection with any sale
or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Subsidiary
Guarantor; 
 (3) only in the case of a Subsidiary Guarantor, if for any reason such Subsidiary Guarantor ceases to be a
Wholly-Owned Subsidiary of the Issuer; provided, that any Subsidiary Guarantor that ceases to constitute a Subsidiary Guarantor or becomes an Excluded Subsidiary solely by virtue of no longer being a Wholly-Owned Subsidiary (a “Partially
Disposed Subsidiary”) shall only be released from its Note Guarantee to the extent that the other person taking an equity interest in such Partially Disposed Subsidiary is not an Affiliate of the Issuer that is controlled by Parent, Deutsche
Telekom or any of their respective subsidiaries or an employee of any of the foregoing; 
 (4) upon Legal Defeasance,
Covenant Defeasance or satisfaction and discharge of this Indenture as provided in ARTICLES VIII and XI hereof; 
 (5) upon
the liquidation or dissolution of any Subsidiary Guarantor, provided that no Event of Default has occurred that is continuing; 

(6) upon the merger or consolidation of any Guarantor with and into the Issuer or another Guarantor that is the surviving
Person in such merger or consolidation; or 
 (7) in the case of a Subsidiary Guarantor, if, immediately following such
release and any concurrent releases of other Guarantees by such Subsidiary Guarantor, the aggregate principal amount of Indebtedness for Borrowed Money of Subsidiaries that are not Guarantors and not Excluded Subsidiaries (excluding any Indebtedness
under any Permitted Receivables Financing and any Indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary) that would remain incurred or issued and
outstanding would not exceed $2,000.0 million. 
 (b) The Trustee shall deliver an appropriate instrument, prepared by
the Issuer, evidencing any release of a Guarantor from the Note Guarantee in respect of any Series of Notes upon receipt of a written request of the Issuer accompanied by an Officer’s Certificate and an Opinion of Counsel to the effect that the
Guarantor is entitled to such release in accordance with the provisions of this Indenture and the other Notes Documents. Any Guarantor not so released shall remain liable for the full amount of principal of, and premium, if any, and interest on the
Notes entitled to the benefits of the Note Guarantee as provided in this Indenture, subject to the limitations of Section 10.02.

 ARTICLE XI 

SATISFACTION AND DISCHARGE 
 Section 11.01
Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to Notes of any Series,
when: 
 (1) either: 

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

(B) all Notes of such Series that have not been delivered to the Trustee for cancellation have become due and payable by reason
of the sending of a notice of redemption or otherwise or will become due and payable within one year and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee or its designee as trust funds in trust solely
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 such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes of such Series not
delivered to the Trustee for cancellation for principal of, and premium, if any, and accrued interest to the date of maturity or redemption; provided that upon any redemption that requires the payment of a premium, the amount deposited shall
be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the premium calculated as of the date of the notice of redemption, with any deficit as of the redemption date only required to be
deposited with the Trustee on or prior to the redemption date; 
 (2) the Issuer or any Guarantor has paid or caused to be
paid all sums payable by it under this Indenture in respect of such Series; and 
 (3) the Issuer has delivered irrevocable
instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes of such Series at Maturity or on the redemption date, as the case may be. 

In addition, the Issuer must deliver to the Trustee (a) an Officer’s Certificate, stating that all conditions precedent set forth in
the Indenture have been satisfied, and (b) an Opinion of Counsel, stating that all conditions precedent set forth in the Indenture have been satisfied. 

  
 -61- 

 Notwithstanding the satisfaction and discharge of this Indenture with respect to Notes of
any Series, if money has been deposited with the Trustee for any Series pursuant to subclause (B) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this
Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of any Series of Notes under this Indenture. 

Section 11.02 Application of Trust Money. 

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

generally in use), including after the Series Issue Date thereof, and, if so, the Trustee will use “CUSIP,” “ISIN” and/or “Common Code” numbers in notices of redemption as a convenience to Holders of Notes of such
Series; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes of such Series or as contained in any notice of a redemption and that reliance may be placed
only on the other elements of identification printed on the Notes of such Series, and any such redemption will not be affected by any defect in or omission of such numbers.

the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy

 2.3 Transfer and Exchange. 

(a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Registrar with a request: 

(x) to register the transfer of such Definitive Notes; or 

(y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, 

the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided,
however, that the Definitive Notes surrendered for transfer or exchange: 
 (i) shall be duly endorsed or accompanied
by a written instrument of transfer in form reasonably satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 

(ii) if such Definitive Notes are required to bear a restricted notes legend, they are being transferred or exchanged pursuant
to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) below or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

 (A) if such Definitive Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder,
without transfer, a certification from such Holder to that effect; or 
 (B) if such Definitive Notes are being transferred
to the Issuer, a certification to that effect; or 
 (C) if such Definitive Notes are being transferred (x) pursuant to
an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act or (y) in reliance upon another exemption from the requirements of the Securities Act: (1) a certification to that effect (in
the form set forth on the reverse of the Note) and (2) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in
Section 2.3(e)(i). 
 (b) Restrictions on Transfer of a Definitive Note for a Beneficial Interest in a Global Note. A Definitive
Note may not be exchanged for a beneficial interest in a Rule 144A Global Note or a Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Note, duly endorsed or accompanied
by appropriate instruments of transfer, together with: 
 (i) certification, in the form set forth on the reverse of the
Note, that such Definitive Note is either (A) being transferred to a QIB in accordance with Rule 144A (B) being transferred to a Person in reliance on Regulation S, or (C) being transferred after expiration of the Distribution
Compliance Period by a Person who initially purchased such security in reliance on Regulation S to a buyer who elects to hold its interest in such security in the form of a beneficial interest in the Regulation S Global Note; and 

  
 Appendix A-4 

 (ii) written instructions directing the Trustee to make, or to direct the
Notes Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Regulation S Global Note (in the case of a transfer pursuant to clause (b)(i)(B)
or (b)(i)(C)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note or Regulation S Global Note, as applicable, such instructions to contain information regarding the Depositary account to be
credited with such increase, then the Trustee shall cancel such Definitive Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Notes Custodian,
the aggregate principal amount of Notes represented by the Rule 144A Global Note or Regulation S Global Note, as applicable, to be increased by the aggregate principal amount of the Definitive Note to be exchanged and shall credit or cause to be
credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note or Regulation S Global Note, as applicable, equal to the principal amount of the Definitive Note so canceled. If no Rule 144A
Global Notes or Regulation S Global Notes, as applicable, are then outstanding, the Issuer shall issue and the Trustee shall authenticate, upon Company Order in the form of an Officer’s Certificate of the Issuer, a new Rule 144A Global Note or
Regulation S Global Note, as applicable, in the appropriate principal amount. 
 (c) Transfer and Exchange of Global Notes. 

(i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in
accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written
order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the Global Note. The Registrar shall, in accordance with such
instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global
Note being transferred. 
 (ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a
beneficial interest in another Global Note, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal
amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred. 

  
 Appendix A-5 

 (iii) Notwithstanding any other provisions of this Appendix (other than the
provisions set forth in Section 2.4), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 (iv) In the event that
a Global Note is exchanged for Definitive Notes pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or prior to or following the effectiveness of a Registration Statement with respect to such
Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Notes intended
to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer. 

(d) Restrictions on Transfer of Regulation S Global Notes. (i) Prior to the expiration of the Distribution Compliance Period,
beneficial ownership interests in the Regulation S Global Note may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (A) to the Issuer, (B) so long as such security is eligible for resale pursuant
to Rule 144A, to a person whom the selling holder reasonably believes is a QIB that purchases for its own account or for the account of a QIB to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A,
(C) in an offshore transaction in accordance with Regulation S, (D) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if applicable), or (E) pursuant to an effective registration statement under
the Securities Act, in each case in accordance with any applicable securities laws of any State of the United States. Prior to the expiration of the Distribution Compliance Period, transfers by an owner of a beneficial interest in the Regulation S
Global Note to a transferee who takes delivery of such interest through the Rule 144A Global Note shall be made only in accordance with Applicable Procedures and upon receipt by the Trustee of a written certification from the transferor of the
beneficial interest in the form provided on the reverse of the Initial Note to the effect that such transfer is being made to a QIB within the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A. Such written certification
shall no longer be required after the expiration of the Distribution Compliance Period. 
 (e) Legends. 

(i) Except as permitted by the following paragraphs (iii), (iv) and (v), each Note certificate evidencing the Global Notes
shall bear a legend in substantially the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS

PERSONS OTHER THAN DISTRIBUTORS (AS DEFINED IN RULE 902 OF REGULATION S) IN RELIANCE ON REGULATION S] ONLY (A)(1) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (2) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE
SECURITIES ACT, (3) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A PURCHASING FOR
ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (4) IN AN OFFSHORE TRANSACTION COMPLYING WITH RULE 903 OR RULE 904 OF REGULATION S UNDER THE

REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. 
 BY ITS ACQUISITION OF THIS SECURITY OR ANY INTEREST
HEREIN, THE HOLDER WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (I) NO PORTION OF THE ASSETS USED BY SUCH HOLDER TO ACQUIRE OR HOLD THIS NOTE OR ANY INTEREST HEREIN CONSTITUTES THE ASSETS OF ANY (A) EMPLOYEE BENEFIT PLAN

 Appendix A-7 

 
(“ERISA”), (B) PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT THAT IS SUBJECT TO SECTION 4975 OF THE U.S. INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”) OR
PROVISIONS UNDER ANY OTHER FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (COLLECTIVELY, “SIMILAR LAWS”), OR (C) ENTITY
WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE “PLAN ASSETS” (WITHIN THE MEANING OF 29 C.F.R. SECTION 2510.3-101 (AS MODIFIED BY SECTION 3(42) OF ERISA) AND ANY SIMILAR LAWS) OF ANY SUCH PLAN,
ACCOUNT OR ARRANGEMENT DESCRIBED IN CLAUSE (A) OR (B) ABOVE (EACH OF (A), (B) AND (C), A “PLAN”), OR (II)(A) THE ACQUISITION, HOLDING AND SUBSEQUENT DISPOSITION OF THIS SECURITY OR ANY INTEREST HEREIN WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS AND (B) NONE OF THE ISSUER, THE APPLICABLE INITIAL PURCHASER(S)
OF THE SECURITY NOR ANY OF THEIR AFFILIATES, IS, BY HAVING MADE ANY ORAL OR WRITTEN STATEMENT REGARDING THE SECURITY, UNDERTAKING TO PROVIDE IMPARTIAL INVESTMENT ADVICE, OR TO GIVE ADVICE IN A FIDUCIARY CAPACITY, IN CONNECTION WITH THE PLAN’S
PURCHASE, HOLDING OR DISPOSITION OF THE SECURITY. 
 Each certificate evidencing a Note offered in reliance on Regulation S shall, in
addition to the foregoing, bear a legend in substantially the following form: 
 BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT
IT IS NOT A U.S. PERSON NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT. 

Each Definitive Note shall also bear the following additional legend: 

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH
TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 
 (ii) Except
as permitted by the following paragraphs (iii), (iv) and (v), each Note certificate evidencing the Definitive Notes shall bear a legend in substantially the following form: 

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF

 Appendix A-8 

 (iii) Upon any sale or transfer of a Transfer Restricted Note (including any
Transfer Restricted Note represented by a Global Note) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a certificated Note that does not bear the legend
set forth above and rescind any restriction on the transfer of such Transfer Restricted Note, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in
the form set forth on the reverse of the Note). 
 (iv) After or in connection with a transfer of any Initial Notes pursuant
to and during the period of the effectiveness of a Registration Statement with respect to such Initial Notes to a person who is not the Issuer or an Affiliate thereof, all requirements pertaining to legends on such Initial Note will cease to apply,
and a certificated Note or a Note in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Notes upon exchange of such transferring Holder’s certificated Initial Note
or directions to transfer such Holder’s interest in the Global Note, as applicable. 
 (v) Upon the occurrence of a
Registered Exchange Offer, the Issuer shall issue and, upon receipt of a Company Order in accordance with Section 2.2, the Trustee shall authenticate, one or more Global Notes or Definitive Notes, as directed by the Holders of the Notes to be
exchanged, not bearing the restricted notes legend in an aggregate principal amount equal to the principal amount of the beneficial interests in the Notes that are Initial Notes tendered for acceptance by a Person other than the Issuer or an
Affiliate thereof in accordance with the Registered Exchange Offer and accepted for exchange in the Registered Exchange Offer. Concurrently with the issuance of such Notes, the Registrar shall cause the aggregate principal amount of the applicable
Initial Notes to be reduced accordingly, and the Registrar shall deliver to the Persons designated by the Holders of the Initial Notes so accepted Notes not bearing the restricted securities legend in the appropriate principal amount. Upon the
consummation of a Registered Exchange Offer with respect to the Initial Notes, Exchange Notes in certificated or global form, in each case without the restricted notes legend set forth in Section 2.3(e) hereof, will be available to Holders
other than the Issuer or an Affiliate thereof that exchange such Initial Notes in such Registered Exchange Offer. 
 (f) Cancellation or
Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Trustee for cancellation or retained
and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note shall
be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction. 

  
 Appendix A-9 

 (g) No Obligation of the Trustee. 

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a
participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery
to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given
to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial
owners in any Global Note shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with
respect to its members, participants and any beneficial owners. 
 (ii) The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary
participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the
Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 2.4 Definitive
Notes. 
 (a) A Global Note deposited with the Depositary or with the Trustee as Notes Custodian for the Depositary pursuant to
Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer
complies with Section 2.3 hereof and (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for such Global Note and the Depositary fails to appoint a successor depositary or if at any time such
Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in either case, a successor depositary is not appointed by the Issuer within 120 days of such notice, or (ii) if requested by such a beneficial owner
after the occurrence and during the continuance of an Event of Default or (iii) the Issuer, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Notes under the Indenture. 

(b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by the
Depositary to the Trustee located at its Corporate Trust Office, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, upon such transfer of

  
 Appendix A-10 

 
each portion of such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.4
shall be executed, authenticated and delivered only in denominations of a minimum of $2,000 principal amount and any integral multiples of $1,000 in excess thereof (unless otherwise provided by Board Resolution, Officer’s Certificate or
supplemental indenture hereto for a particular Series) and registered in such names as the Depositary shall direct. Any Definitive Note delivered in exchange for an interest in the Transfer Restricted Note shall, except as otherwise provided by
Section 2.3(e) hereof, bear the applicable restricted notes legend and definitive notes legend set forth in Section 2.3(e) hereof. 

(c) Subject to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Note shall be entitled to grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes. 

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Issuer shall promptly make available to
the Trustee a reasonable supply of Definitive Notes in definitive, fully registered form without interest coupons. In the event that such Definitive Notes are not issued, the Issuer expressly acknowledges, with respect to the right of any Holder to
pursue a remedy pursuant to Section 6.06 of the Base Indenture, the right of any beneficial owner of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial owner’s Notes as if such
Definitive Notes had been issued.
