“Acquired Indebtedness” means Indebtedness (1) of a Person or any of its Subsidiaries existing at the time such Person
becomes a Restricted Subsidiary, or (2) assumed in connection with the acquisition of assets from such Person, in each case whether or not Incurred by such Person in connection with such Person becoming a Restricted Subsidiary of Holdings or
such acquisition or (3) of a Person at the time such Person merges with or into or consolidates, amalgamates or otherwise combines with Holdings or any Restricted Subsidiary. Acquired Indebtedness shall be deemed to have been Incurred, with
respect to clause (1) of the preceding sentence, on the date such Person becomes a Restricted Subsidiary and, with respect to clause (2) of the preceding sentence, on the date of consummation of such acquisition of assets
and, with respect to clause (3) of the preceding sentence, on the date of the relevant merger, consolidation or other combination. 

 “Acquisition” means the proposed acquisition by Holdings of Lake Region pursuant
to the Merger Agreement. 
 “Additional Assets” means: 

(1) any property or assets (other than Capital Stock) used or to be used by Holdings or a Restricted Subsidiary or otherwise
useful in a Similar Business (it being understood that capital expenditures on property or assets already used in a Similar Business or to replace any property or assets that are the subject of such Asset Disposition shall be deemed an investment in
Additional Assets); or 
 (2) the Capital Stock of a Person that is engaged in a Similar Business and becomes a Restricted
Subsidiary as a result of the acquisition of such Capital Stock by Holdings or a Restricted Subsidiary of Holdings. 

“Affiliate” of any specified Person means any other Person, directly or indirectly, controlling or controlled by or under
direct or indirect common control with such specified Person. For the purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies of such Person, directly or
indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

“Agent” means any Registrar, Paying Agent, Authenticating Agent or Notes Custodian. 

“Alternative Currency” means each of Euro, British Pounds Sterling, Australian Dollars, Brazilian Real, Canadian Dollars,

“Applicable Premium” means, with respect to any Note on any redemption date, the greater of (A) 1.0% of the principal
amount of such Note and (B) the excess (to the extent positive) of: 
 (a) the present value at such redemption date of

to and including such date set forth in clause (i) (excluding accrued but unpaid interest to the redemption date), computed on the redemption date using a discount rate equal to the Applicable Treasury Rate at such redemption date
plus 50 basis points; over 
 (b) the outstanding principal amount of such Note;

November 1, 2018; provided, however, that if the period from the redemption date to November 1, 2018 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the
Applicable Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from
the redemption date to such applicable date is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

 -20- 

 
effect to such Incurrence, assumption, Guarantee, redemption, defeasance, retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as
if the same had occurred at the beginning of the applicable four-quarter period; provided, however, that the pro forma calculation shall not give effect to any Indebtedness Incurred on such determination date pursuant to
Section 3.2(b) (other than Indebtedness Incurred pursuant to Section 3.2(b)(5)). 
 For purposes of making the
computation referred to above, any Investments, acquisitions, dispositions, mergers, consolidations and disposed operations that have been made by Holdings or any of its Restricted Subsidiaries, during the four-quarter reference period or subsequent
to such reference period and on or prior to or simultaneously with the Fixed Charge Coverage Ratio Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, consolidations and
disposed or discontinued operations (and the change in any associated fixed charge obligations and the change in Consolidated EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of
such period any Person that subsequently became a Restricted Subsidiary or was merged with or into Holdings or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger,
consolidation or disposed or discontinued operation that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment,
acquisition, disposition, merger, consolidation or disposed operation had occurred at the beginning of the applicable four-quarter period. 

For purposes of this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good
faith by a responsible financial or chief accounting officer of Holdings subject to the restrictions set forth in the definition of “Consolidated EBITDA” (it being understood for the avoidance of doubt that this definition shall not be
construed to permit adjustments to Consolidated EBITDA (including with respect to cost savings) that are not otherwise permitted by the definition of “Consolidated EBITDA”). If any Indebtedness bears a floating rate of interest and is
being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Fixed Charge Coverage Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging
Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of Holdings to be the rate of interest
implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed with a pro forma basis shall be computed based
upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate,
or other rate, shall be determined to have been based upon the rate actually chosen, or if none, then based upon such optional rate chosen as Holdings may designate.

however, that any such election, once made, shall be irrevocable. At any time after the Issue Date, Holdings may elect to apply IFRS accounting principles in lieu of GAAP and, upon any such election, references herein to GAAP shall thereafter be
construed to mean IFRS (except as otherwise provided in this Indenture), including as to the ability of Holdings to make an election pursuant to the previous sentence; provided that any such election, once made, shall be irrevocable;
provided, however, that any calculation or determination in this Indenture that require the application of GAAP for periods that include fiscal quarters ended prior to Holdings’ election to apply IFRS shall remain as previously
calculated or determined in accordance with GAAP; provided, further, that Holdings may only make such election if it also elects to report any subsequent financial reports required to be made by Holdings, including pursuant to

pursuant to the terms of the instrument embodying such Guarantee or, if such Guarantee is not an unconditional guarantee of the entire amount of the primary obligation and such maximum amount is not stated or determinable, the amount of such
guaranteeing Person’s maximum reasonably anticipated liability in respect thereof as determined by such Person in good faith. The term “Guarantee” used as a verb has a corresponding meaning.

similar facility shall only be “Incurred” at the time any funds are borrowed thereunder.

 ARTICLE II 

THE NOTES 
 SECTION 2.1.
Form, Dating and Terms. 
 (a) The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is
unlimited. The Initial Notes issued on the date hereof shall be in an aggregate principal amount of $360,000,000. In addition, the Issuer may issue, from time to time in accordance with the provisions of this Indenture, Additional Notes.
Furthermore, Notes may be authenticated and delivered upon registration of transfer, exchange or in lieu of, other Notes pursuant to Section 2.2, 2.6, 2.11, 2.13, 5.6 or 9.5, in connection with an Asset
Disposition Offer pursuant to Section 3.5 or in connection with a Change of Control Offer pursuant to Section 3.9. 

  
 -46- 

 Notwithstanding anything to the contrary contained herein, the Issuer may not issue any
Additional Notes, unless such issuance is in compliance with this Indenture, including Section 3.2. 
 With respect to any
Additional Notes, the Issuer shall set forth in (1) a Board Resolution and (2) (i) an Officer’s Certificate and (ii) one or more indentures supplemental hereto, the following information: 

(A) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 

(B) the issue price and the issue date of such Additional Notes, including the date from which interest shall accrue; and 

(C) whether such Additional Notes shall be Restricted Notes. 

In authenticating and delivering Additional Notes, the Trustee shall be entitled to receive and shall be fully protected in relying upon, in
addition to the Opinion of Counsel and Officer’s Certificate required by Section 12.4, an Opinion of Counsel as to the due authorization, execution, delivery, validity and enforceability of such Additional Notes. 

The Initial Notes and the Additional Notes shall be considered collectively as a single class for all purposes of this Indenture;
provided that Additional Notes will not be issued with the same CUSIP or ISIN, as applicable, as existing Notes unless such Additional Notes, are fungible with such existing Notes for U.S. federal income tax purposes and otherwise. Holders of
the Initial Notes and the Additional Notes shall vote and consent together as one class on all matters to which such Holders are entitled to vote or consent, and none of the Holders of the Initial Notes or the Additional Notes shall have the right
to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent. 
 If any of the terms of any
Additional Notes are established by action taken pursuant to a Board Resolution of the Issuer, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Issuer and delivered to the Trustee
at or prior to the delivery of the Officer’s Certificate and an indenture supplemental hereto setting forth the terms of the Additional Notes. 

(b) The Initial Notes are being offered and sold by the Issuer pursuant to the Purchase Agreement. The Initial Notes and any Additional Notes
(if issued as Restricted Notes) (the “Additional Restricted Notes”) will be resold initially only to (A) persons reasonably believed to be QIBs in reliance on Rule 144A and (B) Non-U.S. Persons in reliance on
Regulation S. Such Initial Notes and Additional Restricted Notes may thereafter be transferred to, among others, QIBs, purchasers in reliance on Regulation S, and IAIs, in each case, in accordance with the procedures described herein.
Additional Notes offered after the date hereof may be offered and sold by the Issuer from time to time pursuant to one or more purchase agreements or underwriting agreements, as the case may be, in accordance with applicable law. 

Initial Notes and Additional Restricted Notes offered and sold to QIBs in the United States of America in reliance on Rule 144A (the
“Rule 144A Notes”) shall be issued in the form 

  
 -47- 

 
of a permanent global Note substantially in the form of Exhibit A, which is hereby incorporated by reference and made a part of this Indenture, including appropriate legends as set
forth in Sections 2.1(d) and (e) (the “Rule 144A Global Note”), deposited with the Trustee, as custodian for DTC, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The
Rule 144A Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Rule 144A
Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided. 

Initial Notes and any Additional Restricted Notes offered and sold outside the United States of America (the
“Regulation S Notes”) in reliance on Regulation S shall initially be issued in the form of a temporary global Note (the “Temporary Regulation S Global Note”). Beneficial interests in the Temporary
Regulation S Global Note will be exchanged for beneficial interests in a corresponding permanent global Note substantially in the form of Exhibit A including appropriate legends as set forth in Sections 2.1(d) and
(e) (the “Permanent Regulation S Global Note” and, together with the Temporary Regulation S Global Note, each a “Regulation S Global Note”) within a reasonable period after the expiration
of the Restricted Period (as defined below) upon delivery of the certification contemplated by Exhibit C. Each Regulation S Global Note shall be deposited upon issuance with, or on behalf of, the Trustee as custodian for DTC in the
manner described in this Article II for credit to the respective accounts of the purchasers (or to such other accounts as they may direct), including, but not limited to, accounts at Euroclear Bank S.A./N.V.
(“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”). Prior to the 40th day after the later of the commencement of the offering of the Initial Notes and the Issue Date (such period
through and including such 40th day, the “Restricted Period”), interests in the Temporary Regulation S Global Note may only be transferred to non-U.S. persons pursuant to Regulation S, unless exchanged for interests in a
Global Note in accordance with the transfer and certification requirements described herein. 
 The Regulation S Global Note may be
represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Regulation S Global Note may from time to time
be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided. 

Initial Notes and Additional Restricted Notes resold to IAIs (the “Institutional Accredited Investor Notes”) in the United
States of America shall be issued in the form of a permanent global Note substantially in the form of Exhibit A including appropriate legends as set forth in Sections 2.1(d) and (e) (the “Institutional
Accredited Investor Global Note”) deposited with the Trustee, as custodian for DTC, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The Institutional Accredited Investor Global Note may be represented
by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Institutional Accredited Investor Global Note may from time to
time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided. 

  
 -48- 

 The Rule 144A Global Note, the Regulation S Global Note, the Institutional Accredited
Investor Global Note and any Unrestricted Global Notes are sometimes collectively herein referred to as the “Global Notes.” 

The principal of, premium, if any, and interest on the Notes shall be payable at the office or agency of the Paying Agent designated by the
Issuer and maintained for such purpose (which shall initially be the office of the Trustee maintained for such purpose), or at such other office or agency of the Issuer as may be maintained for such purpose pursuant to Section 2.3;
provided, however, that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes Register or
(ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and
interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC. Payments in respect of Notes represented by Definitive Notes (including principal, premium, if any, and interest) held by a Holder of at least
$1,000,000 aggregate principal amount of Notes represented by Definitive Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or the Paying Agent to such effect designating such account no later than fifteen (15) days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

 The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage, in addition to those set forth on
Exhibit A and in Sections 2.1(d) and (e). The Issuer shall approve any notation, endorsement or legend on the Notes. Each Note shall be dated the date of its authentication. The terms of the Notes set forth in
Exhibit A are part of the terms of this Indenture and, to the extent applicable, the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to be bound by such terms. 

(c) Denominations. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

(d) Restrictive Legends. Unless and until (i) an Initial Note or an Additional Note issued as a Restricted Note is sold under an
effective registration statement or (ii) the Trustee receives an Opinion of Counsel reasonably satisfactory to it stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the
provisions of the Securities Act: 
 (1) the Rule 144A Global Note and the Institutional Accredited Investor Global Note
shall bear the following legend on the face thereof: 
 THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM
REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS NOTE MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH
PURCHASER OF THIS 

  
 -49- 

 
NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER
OF THIS NOTE AGREES FOR THE BENEFIT OF THE ISSUER THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO THE ISSUER, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER
THE SECURITIES ACT, (IV) TO AN “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) THAT, PRIOR TO SUCH TRANSFER, FURNISHES THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN
REPRESENTATIONS AND AGREEMENTS RELATING TO THE TRANSFER OF THIS NOTE (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE) AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF NOTES LESS THAN $250,000, AN OPINION OF COUNSEL
ACCEPTABLE TO THE ISSUER THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (V) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (VI) PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (VI) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER
IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. 
 (2)
the Regulation S Global Note shall bear the following legend on the face thereof: 
 THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY
ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON
EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT. 

  
 -50- 

 (3) the Temporary Regulation S Global Note shall bear the following legend
on the face thereof: 
 THIS SECURITY IS A TEMPORARY REGULATION S GLOBAL NOTE. PRIOR TO THE EXPIRATION OF THE RESTRICTED PERIOD
APPLICABLE HERETO, BENEFICIAL INTERESTS HEREIN MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT
AND ALL APPLICABLE STATE SECURITIES LAWS. BENEFICIAL INTERESTS HEREIN ARE NOT EXCHANGEABLE FOR DEFINITIVE NOTES OTHER THAN A PERMANENT REGULATION S GLOBAL NOTE IN ACCORDANCE WITH THE TERMS OF THE INDENTURE. 

(e) Global Note Legend. Each Global Note, whether or not an Initial Note, shall bear the following legend on the face thereof: 

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION
(“DTC”), NEW YORK, NEW YORK, TO THE ISSUER 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 (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. 
 TRANSFERS OF THIS GLOBAL NOTE SHALL BE
LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO DTC, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF. 
 (f) [Reserved]. 

(g) Book-Entry Provisions. (i) This Section 2.1(g) shall apply only to Global Notes deposited with the Trustee, as
custodian for DTC. 
 (1) Each Global Note initially shall (x) be registered in the name of DTC or the nominee of DTC,
(y) be delivered to the Notes Custodian for DTC and (z) bear the applicable legends as set forth in Section 2.1(e). Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in
whole, but not in part, to DTC, its successors or its respective nominees, except as set forth in Section 2.1(g)(4) 

  
 -51- 

 
and Section 2.1(h). If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, the Notes Custodian will (x) record a
decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial
interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such
Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long
as it remains such an interest. 
 (2) Members of, or participants in, DTC (“Agent Members”) shall have no
rights under this Indenture with respect to any Global Note held on their behalf by DTC or by the Notes Custodian as the custodian of DTC or under such Global Note, and DTC may be treated by the Issuer, the Trustee and any agent of the Issuer or the
Trustee as 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 or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a holder of a beneficial interest in any Global Note.

 (3) In connection with any transfer of a portion of the beneficial interest in a Global Note pursuant to
Section 2.1(h) to beneficial owners who are required to hold Definitive Notes, the Notes Custodian shall reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the
principal amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, one or more Definitive Notes of like tenor and amount. 

(4) In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 2.1(h), such
Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, to each beneficial owner identified by DTC in exchange for its
beneficial interest in such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. 

(5) The registered Holder of a Global Note may 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 this Indenture or the Notes. 

(6) Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such
Global Note may be effected only through a book-entry system maintained by (i) the Holder of such Global Note (or its agent) or (ii) any holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in
such Global Note shall be required to be reflected in a book entry. 

  
 -52- 

 (h) Definitive Notes. Except as provided below, owners of beneficial interests in Global
Notes will not be entitled to receive Definitive Notes. Definitive Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note if (A) DTC notifies the Issuer that it is unwilling or unable to
continue as Depositary for the Global Note, or DTC has ceased to be a clearing agency registered under the Exchange Act, and, in each case, a successor depositary is not appointed or (B) there shall have occurred and be continuing an Event of
Default with respect to the Notes and DTC shall have requested the issuance of Definitive Notes. In the event of the occurrence of any of the events specified in clause (A) or (B) of the preceding sentence, the Issuer shall
promptly make available to the Trustee a reasonable supply of Definitive Notes. In addition, any Note transferred to an affiliate (as defined in Rule 405 under the Securities Act) of the Issuer or evidencing a Note that has been acquired by an
affiliate in a transaction or series of transactions not involving any public offering must, until six months (or one year if the holding period under Rule 144 then applicable to such Note is one year) after the last date on which either the
Issuer or any affiliate of the Issuer was an owner of the Note, be in the form of a Definitive Note and bear the legend regarding transfer restrictions in Section 2.1(d). 

(1) Any Definitive Note delivered in exchange for an interest in a Global Note pursuant to Section 2.1(g) shall,
except as otherwise provided by Section 2.6(d), bear the applicable legend regarding transfer restrictions applicable to the Global Note set forth in Section 2.1(d). 

(2) If a Definitive Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will
(x) cancel such Definitive Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the
entire principal amount of the canceled Definitive Note, the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, to the transferring Holder a new Definitive Note representing the principal amount not so
transferred. 
 (3) If a Definitive Note is transferred or exchanged for another Definitive Note, (x) the Trustee will
cancel the Definitive Note being transferred or exchanged, (y) the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, one or more new Definitive Notes in authorized denominations having an aggregate
principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Definitive Note (in the case of an exchange), registered in the name of such transferee or
Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Issuer shall execute, and the Trustee shall authenticate and make available for delivery to the
Holder thereof, one or more Definitive Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Definitive Notes, registered in the name of the Holder thereof. 

  
 -53- 

 (4) Notwithstanding anything to the contrary in this Indenture, in no event shall
a Definitive Note be delivered upon exchange or transfer of a beneficial interest in the Temporary Regulation S Global Note prior to the end of the Restricted Period. 

SECTION 2.2. Execution and Authentication. One Officer shall sign the Notes for the Issuer by manual, facsimile or other electronic
signature. If the Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless. 

A Note shall not be valid until an authorized officer of the Trustee manually authenticates the Note. The signature of the Trustee on a Note
shall be conclusive evidence that such Note has been duly and validly authenticated and issued under this Indenture. A Note shall be dated the date of its authentication. 

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for
delivery: (1) Initial Notes for original issue on the Issue Date in an aggregate principal amount of $360,000,000 and (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount and
(3) under the circumstances set forth in Section 2.6(e), Initial Notes in the form of an Unrestricted Global Note, in each case upon a written order of the Issuer signed by one Officer (the “Issuer Order”)
provided that the Trustee shall be entitled to receive an Officer’s Certificate and, except in the case of clause (1), an Opinion of Counsel addressing such matters as the Trustee may reasonably request in connection with
such authentication of such Notes. Such Issuer Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be
authenticated, the holder of the Notes and whether the Notes are to be Initial Notes or Additional Notes. 
 The Trustee may appoint an
agent (the “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer.
Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating
Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 
 In case
the Issuer or any Guarantor, pursuant to Article IV or Section 10.2, as applicable, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and
assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Issuer or any Guarantor shall have been merged, or the Person which shall have received a
conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of the Notes authenticated or delivered prior to such consolidation, merger,
conveyance, transfer, lease or other disposition may (but shall not be required), from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology
and form as may be appropriate to reflect such successor Person, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; 

  
 -54- 

 
and the Trustee, upon the Issuer Order of the successor Person, shall authenticate and make available for delivery Notes as specified in such order for the purpose of such exchange. If Notes
shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of
the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered in such new name. 

SECTION 2.3. Registrar and Paying Agent. The Issuer shall maintain an office or agency where Notes may be presented for registration of
transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented for payment. The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Notes
Register”). The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any co-registrar. 

The Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name and address of each such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act
as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. The Issuer or any Guarantor may act as Paying Agent, Registrar or transfer agent. 

The Issuer initially appoints The Depository Trust Company (“DTC”), its nominees and successors to act as Depositary with
respect to the Global Notes. The Issuer has entered into a letter of representations with the Depositary in the form provided by the Depositary. The Trustee in any of its capacities and each Agent are hereby authorized to act in accordance with such
letter of representation and the Applicable Procedures. The Issuer initially appoints the Trustee as the Registrar and Paying Agent for the Notes. The Issuer may remove any Registrar or Paying Agent without prior notice to the Holders, but upon
written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement
entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by Applicable Procedures or (ii) written notification to the
Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuer and the
Trustee. 
 The Issuer shall be responsible for making calculations called for under the Notes and this Indenture, including but not limited
to determination of interest, redemption price, Applicable Premium, premium, if any, and any additional amounts or other amounts payable on the Notes. The Issuer will make the calculations in good faith and, absent manifest error, its calculations
will be final and binding on the Holders. The Issuer will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Issuer’s calculations without
independent verification.

 SECTION 2.4. Paying Agent to Hold Money in Trust. Prior to 10:00 a.m. (New York City
time), on each date on which the principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall deposit with the Paying Agent a sum sufficient (in United States Dollars in immediately available funds) to pay such
principal, premium or interest when due. The Issuer shall require the Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders and the Trustee all money held by such Paying Agent
for the payment of principal of, premium, if any, or interest on the Notes (whether such assets have been distributed to it by the Issuer or other obligors on the Notes), shall notify the Trustee in writing of any default by the Issuer or any
Guarantor in making any such payment and shall during the continuance of any default by the Issuer (or any other obligor upon the Notes) or any Guarantor in the making of any payment in respect of the Notes, upon the written request of the Trustee,
forthwith deliver to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes together with a full accounting thereof. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund for the benefit of the Trustee and the Holders. The Issuer at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for
any funds or assets disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Issuer or a Subsidiary of the Issuer) shall have no further liability for the money delivered to the Trustee.
Upon any bankruptcy, insolvency, reorganization or similar proceeding with respect to the Issuer, the Trustee shall serve as Paying Agent for the Notes. 

SECTION 2.5. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer, on its own behalf and on behalf of each of the Guarantors, shall furnish or cause the Registrar to furnish to the Trustee, in writing at least five
(5) Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders. 

SECTION 2.6. Transfer and Exchange. 

(a) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for
another Note or Notes of any authorized denomination by presenting to the Registrar a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document
required by this Section 2.6. The Registrar will promptly register any transfer or exchange that meets the requirements of this Section 2.6 by noting the same in the Notes Register maintained by the Registrar for the purpose,
and no transfer or exchange will be effective until it is registered in such Notes Register. The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and
Sections 2.1(g) and 2.1(h), as applicable, and, in the case of a Global Note (or a beneficial interest therein), the Applicable Procedures and the applicable rules and procedures of Euroclear and Clearstream. The Registrar shall
refuse to register any requested transfer or exchange that does not comply with this Section 2.6(a). 

  
 -56- 

 (b) Transfers of Rule 144A Notes and Institutional Accredited Investor Notes. The
following provisions shall apply with respect to any proposed registration of transfer of a Rule 144A Note or an Institutional Accredited Investor Note prior to the date that is six months (or one year if the holding period under
Rule 144 then applicable to such Note is one year) after the later of the Issue Date and the last date on which the Issuer or any Affiliate of the Issuer was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction
Termination Date”): 
 (1) a registration of transfer of a Rule 144A Note or an Institutional Accredited
Investor Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Note that it is purchasing for its own account or an account with respect to which it
exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges
that it has received such information regarding the Issuer as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing
representations in order to claim the exemption from registration provided by Rule 144A; provided that no such written representation or other written certification shall be required in connection with the transfer of a beneficial
interest in the Rule 144A Global Note to a transferee in the form of a beneficial interest in that Rule 144A Global Note in accordance with this Indenture and the Applicable Procedures; 

(2) a registration of transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest
therein to an IAI shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Exhibit D from the proposed transferee and the delivery of an Opinion of Counsel, certification and/or
other information satisfactory to the Issuer; and 
 (3) a registration of transfer of a Rule 144A Note or an
Institutional Accredited Investor Note or a beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Issuer and the Registrar or its agent of a certificate substantially in the form set forth in Exhibit E from
the proposed transferee and the delivery of an Opinion of Counsel, certification and/or other information satisfactory to the Issuer. 
 (c)
Transfers of Regulation S Notes. The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the expiration of the Restricted Period: 

(1) a transfer of a Regulation S Note or a beneficial interest therein to a QIB shall be made upon the representation of
the transferee, in the form of assignment on the reverse of the certificate, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a
“qualified institutional buyer” within the meaning of Rule 144A, is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Issuer as the undersigned
has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by
Rule 144A; 

  
 -57- 

 (2) a transfer of a Regulation S Note or a beneficial interest therein to an
IAI shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Exhibit D, respectively, from the proposed transferee and the delivery of an Opinion of Counsel, certification and/or
other information satisfactory to the Issuer; and 
 (3) a transfer of a Regulation S Note or a beneficial interest
therein to a Non-U.S. Person shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Exhibit E from the proposed transferee and receipt by the Registrar or its agent of an Opinion
of Counsel, certification and/or other information satisfactory to the Issuer. 
 After the expiration of the Restricted Period, interests
in the Regulation S Note may be transferred in accordance with applicable law without requiring the certification set forth in Exhibit D, Exhibit E or any additional certification. 

(d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing a Restricted Notes Legend, the Registrar
shall deliver Notes that do not bear a Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing a Restricted Notes Legend, the Registrar shall deliver only Notes that bear a Restricted Notes Legend unless (1) a Note
is being transferred pursuant to an effective registration statement, (2) Notes are being exchanged for other Notes that do not bear the Restricted Notes Legend in accordance with Section 2.6(e) or (3) there is delivered
to the Registrar and the Issuer an Opinion of Counsel satisfactory to the Issuer stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. Any
Additional Notes sold in a registered offering shall not be required to bear the Restricted Notes Legend. 
 (e) Automatic Exchange from
Global Note Bearing Restricted Notes Legend to Global Note Not Bearing Restricted Notes Legend. Upon the Issuer’s satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities
Act, beneficial interests in a Global Note bearing the Restricted Notes Legend (a “Restricted Global Note”) may be automatically exchanged into beneficial interests in a Global Note not bearing the Restricted Notes Legend (an
“Unrestricted Global Note”) without any action required by or on behalf of the Holder (the “Automatic Exchange”) at any time on or after the date that is the 181st calendar day (or the 366th calendar day if the
holding period under Rule 144 then applicable to such Note is one year) after (1) with respect to the Notes issued on the Issue Date or (2) with respect to Additional Notes, if any, the issue date of such Additional Notes, or, in each
case, if such day is not a Business Day, on the next succeeding Business Day (the “Automatic Exchange Date”). Upon the Issuer’s satisfaction that the Restricted Notes Legend shall no longer be required in order to maintain
compliance with the Securities Act, the Issuer shall (i) provide written notice to DTC and the Trustee at least fifteen (15) calendar days prior to the Automatic Exchange Date, instructing DTC to exchange all of the outstanding beneficial
interests in a particular Restricted Global Note to the Unrestricted Global Note, which 

  
 -58- 

 
the Issuer shall have previously otherwise made eligible for exchange with the DTC, (ii) provide prior written notice (the “Automatic Exchange Notice”) to each Holder at
such Holder’s address appearing in the register of Holders at least fifteen (15) calendar days prior to the Automatic Exchange Date (the “Automatic Exchange Notice Date”), which notice must include (w) the
Automatic Exchange Date, (x) the section of this Indenture pursuant to which the Automatic Exchange shall occur, (y) the “CUSIP” number of the Restricted Global Note from which such Holder’s beneficial interests will be
transferred and (z) the “CUSIP” number of the Unrestricted Global Note into which such Holder’s beneficial interests will be transferred, and (iii) on or prior to the Automatic Exchange Date, deliver to the Trustee for
authentication one or more Unrestricted Global Notes, duly executed by the Issuer, in an aggregate principal amount equal to the aggregate principal amount of Restricted Global Notes to be exchanged into such Unrestricted Global Notes. At the
Issuer’s written request on no less than five (5) calendar days’ notice prior to the Automatic Exchange Notice Date, the Trustee shall send, in the Issuer’s name and at its expense, the Automatic Exchange Notice to each Holder at
such Holder’s address appearing in the register of Holders; provided that the Issuer has delivered to the Trustee the information required to be included in such Automatic Exchange Notice. 

Notwithstanding anything to the contrary in this Section 2.6(e), during the fifteen (15) calendar day period prior to the
Automatic Exchange Date, no transfers or exchanges of Notes other than pursuant to this Section 2.6(e) shall be permitted without the prior written consent of the Issuer. As a condition to any Automatic Exchange, the Issuer shall
provide, and the Trustee shall be entitled to conclusively rely upon, an Officer’s Certificate and Opinion of Counsel to the Issuer stating that the Automatic Exchange shall be effected in compliance with the Securities Act and that the
restrictions on transfer contained herein and in the Restricted Notes Legend shall no longer be required in order to maintain compliance with the Securities Act and that the aggregate principal amount of the particular Restricted Global Note is to
be transferred to the particular Unrestricted Global Note by adjustment made on the records of the Trustee, as custodian for the Depositary to reflect the Automatic Exchange. Upon such exchange of beneficial interests pursuant to this
Section 2.6(e), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, to reflect the relevant increase or decrease in the
principal amount of such Global Note resulting from the applicable exchange. The Restricted Global Note from which beneficial interests are transferred pursuant to an Automatic Exchange shall be cancelled following the Automatic Exchange. 

(f) Retention of Written Communications. The Registrar shall retain copies of all letters, notices and other written communications
received pursuant to Section 2.1 or this Section 2.6, in accordance with applicable law and the Registrar’s customary procedures. The Issuer shall have the right to inspect and make copies of all such letters, notices or
other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar. 
 (g)
Obligations with Respect to Transfers and Exchanges of Notes. To permit registrations of transfers and exchanges, the Issuer shall, subject to the other terms and conditions of this Article II, execute and the Trustee shall
authenticate Definitive Notes and Global Notes at the Issuer’s and Registrar’s written request. 

  
 -59- 

 No service charge shall be made to a Holder for any registration of transfer or exchange, but the
Issuer may require the Holder to pay a sum sufficient to cover any transfer tax assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon
exchange or transfer pursuant to Section 2.2, 2.6, 2.11, 2.13, 5.6 or 9.5). 
 The Issuer
(and the Registrar) shall not be required to register the transfer of or exchange of any Note (A) for a period beginning (1) fifteen (15) calendar days before the mailing or sending of a notice of an offer to repurchase or redeem
Notes and ending at the close of business (New York City time) on the day of such mailing or sending or (2) fifteen (15) calendar days before an interest payment date and ending on such interest payment date or (B) called for
redemption, except the unredeemed portion of any Note being redeemed in part or any Note not redeemed due to the failure of a condition precedent to the redemption. 

Prior to the due presentation for registration of transfer of any Note, the Issuer, the Trustee, the Paying Agent or the Registrar may deem
and treat the person in whose name a Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to paragraph 2 of the form of Notes attached hereto as Exhibit A)
interest on such Note and for all other purposes whatsoever, including without limitation the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Issuer, the Trustee, the Paying Agent or the Registrar shall be
affected by notice to the contrary. 
 Any Definitive Note delivered in exchange for an interest in a Global Note pursuant to
Section 2.1(h) shall, except as otherwise provided by Section 2.6(d), bear the applicable legends regarding transfer restrictions applicable to the Definitive Note set forth in Section 2.1(d). 

All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to
the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange. 
 (h) No Obligation of the Trustee.
The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in, DTC or other Person with respect to the accuracy of the records of DTC 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 DTC) of any notice (including any notice of redemption or purchase) or the payment
of any amount or delivery of any Notes (or other security or property) 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 in respect of the Notes shall be given or
made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through DTC and subject to the Applicable
Procedures. The Trustee may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or 

  
 -60- 

 
among DTC 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 this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Neither the Trustee nor any of its agents shall have any
responsibility for any actions taken or not taken by DTC. 
 SECTION 2.7. [Reserved]. 

SECTION 2.8. [Reserved]. 

SECTION 2.9. [Reserved]. 

SECTION 2.10. [Reserved]. 

SECTION 2.11. Mutilated, Destroyed, Lost or Stolen Notes. 

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Issuer and the Trustee that such
Note has been lost, destroyed or wrongfully taken within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes
such request to the Issuer and the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other
reasonable requirements of the Trustee; provided, however, if after the delivery of such replacement Note, a protected purchaser of the Note for which such replacement Note was issued presents for payment or registration such replaced
Note, the Trustee and/or the Issuer shall be entitled to recover such replacement Note from the Person to whom it was issued and delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuer or the Trustee in connection therewith. Such Holder shall furnish an indemnity bond sufficient in the judgment of the (i) Trustee
to protect the Trustee and (ii) the Issuer to protect the Issuer, the Trustee, the Paying Agent and the Registrar, from any loss which any of them may suffer if a Note is replaced, and, in the absence of notice to the Issuer, any Guarantor or
the Trustee that such Note has been acquired by a protected purchaser, the Issuer shall execute, and upon receipt of an Issuer Order, the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Note or in lieu
of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuer in its discretion may,
instead of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note under this Section 2.11, the Issuer may
require that such Holder pay a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and of the Trustee) in connection therewith. 

  
 -61- 

 Subject to the proviso in the initial paragraph of this Section 2.11, every new Note
issued pursuant to this Section 2.11, in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer, any Guarantor (if applicable) and any other obligor upon the
Notes, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

 The provisions of this Section 2.11 are exclusive and shall 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 2.12. Outstanding Notes. Notes
outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those paid pursuant to Section 2.11 and those described in this Section 2.12 as not
outstanding. A Note does not cease to be outstanding in the event the Issuer or an Affiliate of the Issuer holds the Note; provided, however, that (i) for purposes of determining which Notes are outstanding for consent or voting
purposes hereunder, the provisions of Section 12.6 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes are
present at a meeting of Holders of Notes for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum,
consent or vote, only Notes which a Trust Officer of the Trustee actually knows to be held by the Issuer or an Affiliate of the Issuer shall not be considered outstanding. 

If a Note is replaced pursuant to Section 2.11 (other than a mutilated Note surrendered for replacement), it ceases to be
outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement pursuant to
Section 2.11. 
 If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or
maturity date, money (in United States Dollars in immediately available funds) sufficient to pay all principal, premium, if any, and accrued interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as
the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture or the notice of redemption, if any, then on and after that date such Notes (or portions thereof)
cease to be outstanding and interest on them ceases to accrue. 
 SECTION 2.13. Temporary Notes. In the event that Definitive Notes
are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry
all rights, of Definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the 

  
 -62- 

 
Issuer shall prepare and the Trustee shall authenticate Definitive Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender
of the temporary Notes at any office or agency maintained by the Issuer for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute, and the
Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall
in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes. 
 SECTION 2.14. Cancellation.
The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else
shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Notes in accordance with its internal policies and customary procedures (subject to the record retention requirements of the
Exchange Act and the Trustee). If the Issuer or any Guarantor acquires any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to
the Trustee for cancellation pursuant to this Section 2.14. The Issuer may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

 At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, transferred, redeemed,
repurchased or canceled, such Global Note shall be returned by DTC 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, transferred in exchange for an interest in another Global Note, redeemed, repurchased 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. 

SECTION 2.15. Payment of Interest; Defaulted Interest. Interest on any Note which is payable, and is punctually paid or duly provided
for, on any interest payment date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business (New York City time) on the regular record date for such payment at the office or agency
of the Issuer maintained for such purpose pursuant to Section 2.3. 
 Any interest on any Note which is payable, but is not paid
when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date, and such defaulted interest and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Issuer, at its election in each case, as provided in
clause (a) or (b) below: 
 (a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in
whose names the Notes (or their respective predecessor Notes) are registered at the close of 

  
 -63- 

 
business (New York City time) on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time
the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Section 2.15(a). Thereupon the Issuer shall fix a record date (the “Special
Record Date”) for the payment of such Defaulted Interest, which date shall be not more than twenty (20) calendar days and not less than fifteen (15) calendar days prior to the Special Interest Payment Date and not less than ten
(10) calendar days after the receipt by the Trustee of the notice of the proposed payment. The Issuer shall promptly notify the Trustee in writing of such Special Record Date, and in the name and at the expense of the Issuer, the Trustee shall
cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.2, not less than ten (10) calendar days
prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest

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 or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and
any such redemption or purchase shall not be affected by any defect in or omission of such CUSIP and ISIN numbers. The Issuer shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

(c) For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and
in compliance with, this Section 3.2: 
 (1) subject to Section 3.2(c)(3), in the event that all or
any portion of any item of Indebtedness meets the criteria of more than one of the types of Indebtedness described in Sections 3.2(a) and (b), Holdings, in its sole discretion, may classify, and may from time to time reclassify
under Section 3.2(c)(2), such item of Indebtedness and only be required to include the amount and type of such Indebtedness in one of the clauses of Section 3.2(a) or (b); 

(2) subject to Section 3.2(c)(3), all or any portion of any item of Indebtedness may later be classified as having been
Incurred pursuant to any type of Indebtedness described in Sections 3.2(a) and (b) so long as such Indebtedness is permitted to be Incurred pursuant to such provision at the time of reclassification; 

(3) all Indebtedness outstanding on the Issue Date under the Credit Agreement shall be deemed to have been

(4) in the case of the incurrence of any Refinancing Indebtedness under clauses (7), (10) or (13) of

 -68- 

 (8) the amount of any Indebtedness outstanding as of any date shall be
(i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount of Indebtedness, or liquidation preference thereof, in the case of any other Indebtedness. 

(d) Accrual of interest, accrual of dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the
payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock or the reclassification of commitments or obligations not treated as Indebtedness due to a
change in GAAP, shall not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.2. 
 (e) If at any time
an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary of Holdings as of such date (and, if such Indebtedness is not permitted to be Incurred as of
such date under this Section 3.2, such will constitute a default of this Section 3.2). 
 (f) Notwithstanding any
other provision of this Section 3.2, the maximum amount of Indebtedness that Holdings or a Restricted Subsidiary may Incur pursuant to this Section 3.2 shall not be deemed to be exceeded solely as a result of fluctuations in
the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in the same currency as the Indebtedness being refinanced, shall be calculated based on the currency exchange rate in
effect on the date such Indebtedness was originally incurred, in the case of term indebtedness, or first committed, in the case of revolving credit indebtedness. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if
Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such
refinancing. 
 (g) Holdings and the Issuer shall not, and shall not permit any Guarantor to, directly or indirectly, Incur any Indebtedness
(including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of Holdings, the Issuer or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the
Notes or such Guarantor’s Note Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of Holdings, the Issuer or such Guarantor, as the case may be. 

(h) (1) Unsecured Indebtedness shall not be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured, and
(2) senior Indebtedness shall not be treated as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral or is secured by different collateral or because it is
guaranteed by different obligors.

pursuant to this Section 3.3(b)(18)(y) since the Issue Date, does not exceed $25,000,000. 
 (c) The amount of all Restricted
Payments (other than cash) shall be the fair market value on the date of such Restricted Payment of the asset(s) or securities proposed to be paid, transferred or issued by Holdings or such Restricted Subsidiary, as the case may be, pursuant to such
Restricted Payment. The fair market value of any cash Restricted Payment shall be its face amount, and the fair market value of any non-cash Restricted Payment, property or assets other than cash shall be determined in accordance with the definition
of “fair market value.” 
 SECTION 3.4. Limitation on Restrictions on Distributions from Restricted Subsidiaries. 

(a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(2) make any loans or advances to Holdings or any Restricted Subsidiary; or 

(3) sell, lease or transfer any of its property or assets to Holdings or any Restricted Subsidiary; 

provided that (x) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating
distributions being paid on common stock and (y) the subordination of (including the application of any standstill requirements to) loans or advances made to Holdings or any Restricted Subsidiary to other Indebtedness Incurred by Holdings or
any Restricted Subsidiary shall not be deemed to constitute such an encumbrance or restriction. 
 (b) Section 3.4(a) shall not
prohibit: 
 (1) any encumbrance or restriction pursuant to (a) any Credit Facility (and any Hedging Obligations and
Cash Management Services related thereto), or (b) any other agreement or instrument of Holdings or any Subsidiary of Holdings in effect or entered into on the Issue Date; 

(2) any encumbrance or restriction pursuant to this Indenture, the Notes and the Note Guarantees;

 -76- 

 
otherwise combined with or into Holdings or any Restricted Subsidiary, or was designated as a Restricted Subsidiary or on which such agreement or instrument is assumed by Holdings or any
Restricted Subsidiary in connection with an acquisition of assets (other than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related
transactions pursuant to which such Person became a Restricted Subsidiary or was acquired by Holdings or was merged, consolidated or otherwise combined with or into Holdings or any Restricted Subsidiary or entered into in contemplation of or in
connection with such transaction) and outstanding on such date which encumbrance or restriction is not applicable to any Person or the properties or assets of any Person, other than the Person, or the properties or assets of the Person, so acquired;
provided that, for the purposes of this clause (3), if another Person is the Successor Company, any Subsidiary thereof or agreement or instrument of such Person or any such Subsidiary shall be deemed acquired or assumed by
Holdings or any Restricted Subsidiary when such Person becomes the Successor Company; 
 (4) any encumbrance or restriction:

 (i) that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject
to a lease, license or similar contract or agreement, or the assignment or transfer of any lease, license or other contract or agreement; 

(ii) contained in mortgages, pledges, charges or other security agreements permitted under this Indenture or securing
Indebtedness of Holdings or a Restricted Subsidiary permitted under this Indenture to the extent such encumbrances or restrictions restrict the transfer or encumbrance of the property or assets subject to such mortgages, pledges, charges or other
security agreements; or 
 (iii) pursuant to customary provisions restricting dispositions of real property interests set
forth in any reciprocal easement agreements of Holdings or any Restricted Subsidiary; 
 (5) any encumbrance or restriction

restriction on cash or other deposits or net worth imposed by customers under agreements entered into in the ordinary course of business or consistent with past practice; 

(10) any customary encumbrance or restriction pursuant to Hedging Obligations; 

(11) other Indebtedness, Disqualified Stock or Preferred Stock of Foreign Subsidiaries permitted to be Incurred or issued
subsequent to the Issue Date pursuant to Section 3.2 that impose restrictions solely on the Foreign Subsidiaries party thereto or their Subsidiaries; 

(12) any encumbrance or restriction required by the terms of any agreement relating to a Qualified Receivables Transaction;
provided, however, that such encumbrance or restriction applies only to such Qualified Receivables Transaction; 

(13) any encumbrance or restriction arising pursuant to an agreement or instrument (which, if it relates to any Indebtedness,
shall only be permitted if such Indebtedness is permitted to be Incurred pursuant to Section 3.2) if the encumbrances and restrictions contained in any such agreement or instrument taken as a whole (i) are not materially less
favorable to the Holders than the encumbrances and restrictions contained in the Credit Agreement, together with the security documents associated therewith, as in effect on the Issue Date (as determined in good faith by Holdings) or
(ii) either (A) the Issuer determines at the time of entry into such agreement or instrument that such encumbrances or restrictions shall not adversely affect, in any material respect, the Issuer’s ability to make principal or
interest payments on the Notes or (B) such encumbrance or restriction applies only during the continuance of a default relating to such agreement or instrument; 

(14) any encumbrance or restriction existing by reason of any lien permitted under Section 3.6; or

contained in any amendment, supplement or other modification to an agreement referred to in clauses (1) to (14) of this Section 3.4(b) or this clause (15); provided, however, that the
encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement or instrument are no less favorable in any material respect to the Holders taken as a whole than the encumbrances and restrictions contained in
the Initial Agreement or Initial Agreements to which such refinancing or amendment, supplement or other modification relates (as determined in good faith by Holdings). 

  
 -78- 

 SECTION 3.5. Limitation on Sales of Assets and Subsidiary Stock. 

(a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: 

(1) Holdings or such Restricted Subsidiary, as the case may be, receives consideration (including by way of relief from, or by
any other Person assuming responsibility for, any liabilities, contingent or otherwise) at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition) of the shares
and assets subject to such Asset Disposition (including, for the avoidance of doubt, if such Asset Disposition is a Permitted Asset Swap); 

(2) in any such Asset Disposition or series of related Asset Dispositions (except to the extent the Asset Disposition is a
Permitted Asset Swap), at least 75% of the consideration from such Asset Disposition (including by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise) received by Holdings or such
Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and 
 (3) Holdings or any of its
Restricted Subsidiaries, will apply 100% of the Net Available Cash from any Asset Disposition at its option: 
 (i) to the
extent Holdings or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Indebtedness), (A) to prepay, repay or purchase any Indebtedness of a Non-Guarantor or Indebtedness that is secured by a Lien (in each
case, other than Indebtedness owed to Holdings or any Restricted Subsidiary) within 365 days from the later of (1) the date of such Asset Disposition and (2) the receipt of such Net Available Cash; provided, however,
that, in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (i), Holdings or such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be reduced
in an amount equal to the principal amount so prepaid, repaid or purchased; or (B) to prepay, repay or purchase Senior Indebtedness; provided further that, to the extent Holdings redeems, repays or repurchases Senior Indebtedness
pursuant to this clause (B), the Issuer shall equally and ratably reduce Obligations under the Notes pursuant to Section 5.7, through open-market purchases (to the extent such purchases are at or above 100% of the principal
amount thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Disposition Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest,
if any, on the amount of Notes that would otherwise be prepaid; and/or 
 (ii) to the extent Holdings or any Restricted
Subsidiary elects, to invest in or commit to invest in Additional Assets (including by means of an investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by Holdings or another Restricted Subsidiary) within
365 days from the later of 

  
 -79- 

 
(A) the date of such Asset Disposition and (B) the receipt of such Net Available Cash; provided, however, that a binding agreement shall be treated as a permitted
application of Net Available Cash from the date of such commitment so long as Holdings or the applicable Restricted Subsidiary has the good faith expectation that such Net Available Cash will be applied to satisfy such commitment within
180 days of such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Available Cash is applied in connection therewith, Holdings or
such Restricted Subsidiary enters into another Acceptable Commitment (a “Second Commitment”) within 180 days of such cancellation or termination; provided further that if any Second Commitment is later cancelled or
terminated for any reason before such Net Available Cash is applied, then such Net Available Cash shall constitute Excess Proceeds; 
 provided,
however, that, pending the final application of any such Net Available Cash in accordance with Section 3.5(a)(3)(i) or (ii), Holdings and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise use such
Net Available Cash in any manner not prohibited by this Indenture. 
 (b) Any Net Available Cash from Asset Dispositions that is not applied
or invested or committed to be applied or invested as provided in Section 3.5(a) shall be deemed to constitute “Excess Proceeds” under this Indenture. On the 366th day after an Asset Disposition or the receipt of such
Net Available Cash, as applicable, if the aggregate amount of Excess Proceeds under this Indenture exceeds $10,000,000, the Issuer shall within ten (10) Business Days be required to make an offer (“Asset Disposition Offer”) to
all Holders of Notes issued under this Indenture and, to the extent the Issuer elects, to all holders of other outstanding Senior Indebtedness, to purchase the maximum principal amount of Notes and any such Senior Indebtedness to which the Asset
Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price equal to 100% of the principal amount of the Notes, and Senior Indebtedness, in each case, plus accrued and unpaid interest, if any, to, but not including,
the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Senior Indebtedness, as applicable, and, with respect to the Notes, in minimum denominations of $2,000 and in integral multiples of
$1,000 in excess thereof. The Issuer shall deliver notice of such Asset Disposition Offer electronically or by first-class mail, with a copy to the Trustee, to each Holder of Notes at the address of such Holder appearing in the security register or
otherwise in accordance with the Applicable Procedures, describing the transaction or transactions that constitute the Asset Disposition and offering to repurchase the Notes for the specified purchase price on the date specified in the notice, which
date shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered, pursuant to the procedures required by this Indenture and described in such notice. 

(c) To the extent that the aggregate amount of Notes and Senior Indebtedness so validly tendered and not properly withdrawn pursuant to an
Asset Disposition Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for any purpose not prohibited by this Indenture. If the aggregate principal amount of the Notes surrendered in any Asset Disposition Offer by
Holders and other Senior Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Excess Proceeds shall be 

  
 -80- 

 
allocated by the Issuer among the Notes and Senior Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Senior Indebtedness;
provided that no Notes or other Senior Indebtedness shall be selected and purchased in an unauthorized denomination. Upon completion of any Asset Disposition Offer, the amount of Excess Proceeds will be reset at zero. 

(d) To the extent that any portion of Net Available Cash payable in respect of the Notes is denominated in a currency other than United States
Dollars, the amount thereof payable in respect of the Notes shall not exceed the net amount of funds in United States Dollars that is actually received by the Issuer upon converting such portion into United States Dollars. 

(e) Notwithstanding any other provisions of this Section 3.5, (i) to the extent that any of or all the Net Available Cash of
any Asset Disposition by a Foreign Subsidiary of Holdings (a “Foreign Disposition”) is prohibited or delayed by applicable local law, or would give rise to a violation of a third-party agreement of Holdings, the Issuer or any
Restricted Subsidiary, from being repatriated to the United States, the portion of such Net Available Cash so affected will not be required to be applied in compliance with this Section 3.5, and such amounts may be retained by the
applicable Foreign Subsidiary so long, but only so long, as the applicable local law or third-party agreement will not permit repatriation to the United States (the Issuer hereby agreeing to use reasonable efforts (as determined in the Issuer’s
reasonable business judgment) to otherwise cause the applicable Foreign Subsidiary to within one year following the date on which the respective payment would otherwise have been required, to promptly take all actions reasonably required by the
applicable local law or third-party agreement to permit such repatriation), and if within one year following the date on which the respective payment would otherwise have been required, such repatriation of any of such affected Net Available Cash is
permitted under the applicable local law or third-party agreement, such repatriation will be promptly effected and such repatriated Net Available Cash will be promptly (and in any event not later than five (5) Business Days after such
repatriation could be made) applied by the Issuer (net of additional Taxes payable or reserved against as a result thereof) in compliance with this Section 3.5 and (ii) to the extent that the Issuer has determined in good faith that
repatriation of any of or all the Net Available Cash of any Foreign Disposition would have an adverse Tax cost consequence with respect to such Net Available Cash (which for the avoidance of doubt, includes, but is not limited to, any prepayment
whereby doing so the Issuer, any Restricted Subsidiary or any of their respective affiliates would incur a tax liability, including a tax dividend, deemed dividend pursuant to Code Section 956 or a withholding tax), the Net Available Cash so
affected may be retained by the applicable Foreign Subsidiary. The nonapplication of any prepayment amounts as a consequence of the foregoing provisions will not, for the avoidance of doubt, constitute a Default or an Event of Default. 

(f) For the purposes of Section 3.5(a)(2), the following will be deemed to be cash: 

(i) the assumption by the transferee of Indebtedness or other liabilities contingent or otherwise of Holdings or a Restricted
Subsidiary (other than Subordinated Indebtedness of Holdings, the Issuer or a Subsidiary Guarantor) and the release of Holdings or such Restricted Subsidiary from all liability on such Indebtedness or other liability in connection with such Asset
Disposition; 

  
 -81- 

 (ii) securities, notes or other obligations received by Holdings or any
Restricted Subsidiary of Holdings from the transferee that are converted by Holdings or such Restricted Subsidiary into cash or Cash Equivalents within 180 days following the closing of such Asset Disposition; 

(iii) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset
Disposition, to the extent that Holdings and each other Restricted Subsidiary are released from any Guarantee of payment of such Indebtedness in connection with such Asset Disposition; 

(iv) consideration consisting of Indebtedness of Holdings (other than Subordinated Indebtedness) received after the Issue Date
from Persons who are not Holdings or any Restricted Subsidiary; and 
 (v) any Designated Non-Cash Consideration received by
Holdings or any Restricted Subsidiary in such Asset Dispositions having an aggregate fair market value, taken together with all other Designated Non-Cash Consideration received pursuant to this Section 3.5 that is at that time
outstanding, not to exceed $50,000,000 (with the fair market value of each item of Designated Non-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value). 

(g) Upon the commencement of an Asset Disposition Offer, the Issuer shall send, or cause to be sent, electronically or by first class mail, a
notice to the Trustee and to each Holder at its registered address, in accordance with the Applicable Procedures. The notice shall contain all instructions and materials necessary to enable such Holder to tender Notes pursuant to the Asset
Disposition Offer. Any Asset Disposition Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Disposition Offer, shall state: 

(1) that the Asset Disposition Offer is being made pursuant to this Section 3.5 and that, to the extent lawful, all
Notes tendered and not withdrawn shall be accepted for payment (unless prorated); 
 (2) the Asset Disposition payment
amount, the Asset Disposition offered price, and the date on which Notes tendered and accepted for payment shall be purchased, which date shall be at least 30 days and not later than 60 days from the date such notices are mailed or sent
(the “Asset Disposition Payment Date”); 
 (3) that any Notes not tendered or accepted for payment shall
continue to accrue interest in accordance with the terms thereof; 
 (4) that, unless the Issuer defaults in making such
payment, any Notes accepted for payment pursuant to the Asset Disposition Offer shall cease to accrue interest on and after the Asset Disposition Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to any Asset Disposition Offer shall be required to surrender
the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice at least three (3) Business Days before the Asset Disposition
Payment Date; 

  
 -82- 

 (6) that Holders shall be entitled to withdraw their election if the Paying Agent
receives, not later than two (2) Business Days prior to the Asset Disposition Payment Date, a notice setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is
withdrawing its election to have such Note purchased; 
 (7) that if the aggregate principal amount of Notes surrendered by
Holders exceeds the Asset Disposition payment amount, the Issuer shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $2,000 or
integral multiples of $1,000 remain outstanding after purchase); and 
 (8) that Holders whose Notes were purchased only in
part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry). 

(h) If the Asset Disposition Payment Date is on or after a record date and on or before the related interest payment date, any accrued and
unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business (New York City time) on such record date, and no other interest, if any, shall be payable to Holders who tender Notes pursuant to the Asset
Disposition Offer. 
 (i) On the Asset Disposition Payment Date, the Issuer will, to the extent permitted by law, 

(1) accept for payment all Notes issued by it or portions thereof properly tendered pursuant to the Asset Disposition Offer,

 (2) deposit by 10:00 a.m. (New York City time) with the Paying Agent an amount (in United States Dollars in immediately
available funds) equal to the aggregate Asset Disposition payment in respect of all Notes or portions thereof so tendered, and 

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officer’s
Certificate to the Trustee stating that such Notes or portions thereof have been tendered to and purchased by the Issuer. 
 (j) The Issuer
will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase
of Notes pursuant to this Section 3.5. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 

  
 -83- 

 SECTION 3.6. Limitation on Liens. 

(a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or permit to exist
any Lien (except Permitted Liens) (each, an “Initial Lien”) that secures obligations under any Indebtedness or any related guarantee, on any asset or property of Holdings or any Restricted Subsidiary, unless: 

(1) in the case of Liens securing Subordinated Indebtedness, the Notes and related Guarantees are secured by a Lien on such
property, assets or proceeds that is senior in priority to such Liens; or 
 (2) in all other cases, the Notes and the
related Note Guarantees are equally and ratably secured with the Obligations secured by such Initial Lien. 
 (b) Any Lien created for the
benefit of the Holders pursuant to Section 3.6(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 

(c) With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such
Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any
accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion of original issue discount or liquidation preference and
increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness. 

SECTION 3.7. Limitation on Guarantees. 

(a) Holdings shall not permit any of its Domestic Subsidiaries, other than the Issuer or a Guarantor, to Guarantee the payment of any capital
markets debt securities of Holdings, the Issuer or any Guarantor or Indebtedness under the Credit Agreement or any other Credit Facilities of Holdings, the Issuer or any Guarantor, in each case unless: 

(1) such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture
substantially in the form of Exhibit B providing for a Note Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of Holdings, the Issuer or any Subsidiary Guarantor, if such Indebtedness is by
its express terms subordinated in right of payment to the Notes or such Guarantor’s Note Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee
substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s Note Guarantee; and 

(2) such Restricted Subsidiary shall deliver to the Trustee an Officer’s Certificate stating that: 

(i) such Note Guarantee has been duly authorized, executed and delivered; and 

  
 -84- 

 (ii) such Note Guarantee constitutes a valid, binding and enforceable obligation
of such Restricted Subsidiary, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws (including all laws relating to fraudulent transfers) and except insofar as enforcement thereof is subject to general
principals of equity; 
 provided that this Section 3.7 shall not be applicable in the event that the Guarantee of the Issuer’s
obligations under the Notes or this Indenture by such Subsidiary would not be permitted under applicable law. 
 (b) Holdings may elect, in
its sole discretion, to cause any Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor. 
 SECTION 3.8.
Limitation on Affiliate Transactions. 
 (a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any property or the rendering of any service) with any Affiliate of Holdings (an “Affiliate Transaction”) involving aggregate
value in excess of $10,000,000 unless: 
 (1) the terms of such Affiliate Transaction taken as a whole are not materially
less favorable to Holdings or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction or the execution of the agreement providing for such transaction in
arm’s length dealings with a Person who is not such an Affiliate; and 
 (2) in the event such Affiliate Transaction
involves an aggregate value in excess of $25,000,000, the terms of such transaction have been approved by a majority of the members of the Disinterested Directors. 

(b) Section 3.8(a) shall not apply to: 

(1) any Restricted Payment permitted to be made pursuant to Section 3.3, or any Permitted Investment; 

(2) any issuance or sale of Capital Stock, options, other equity-related interests or other securities, or other payments,
awards or grants in cash, securities or otherwise pursuant to, or the funding of, or entering into, or maintenance of, any employment, consulting, collective bargaining or benefit plan, program, agreement or arrangement, related trust or other
similar agreement and other compensation arrangements, options, warrants or other rights to purchase Capital Stock of Holdings or any Restricted Subsidiary, restricted stock plans, long-term incentive plans, stock appreciation rights plans,
participation plans or similar employee benefits or consultants’ plans (including valuation, health, insurance, deferred compensation, severance, retirement, savings or similar plans, programs or arrangements) or indemnities provided on behalf

 -85- 

 (3) [reserved]; 

(4) any transaction between or among Holdings and any Restricted Subsidiary (or entity that becomes a Restricted Subsidiary as
a result of such transaction), or between or among Restricted Subsidiaries;

reimbursement of expenses to, and customary indemnities (including under customary insurance policies) and employee benefit and pension expenses provided on behalf of, directors, officers, consultants or employees of Holdings or any Restricted
Subsidiary (whether directly or indirectly and including through any Person owned or controlled by any of such directors, officers or employees); 

(6) the entry into and performance of obligations of Holdings or any Restricted Subsidiary under the terms of any transaction
arising out of, and any payments pursuant to or for purposes of funding, any agreement or instrument in effect as of or on the Issue Date, in each case, as these agreements and instruments may be amended, modified, supplemented, extended, renewed or
refinanced from time to time in accordance with the other terms of this Section 3.8 or to the extent not more disadvantageous to the Holders in any material respect; 

(7) any transaction pursuant to a Qualified Receivables Transaction; 

(8) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary
course of business or consistent with past practice, which are fair to Holdings or the relevant Restricted Subsidiary in the reasonable determination of the Board of Directors of Holdings or the senior management of Holdings or the relevant
Restricted Subsidiary, or are on terms no less favorable than those that could reasonably have been obtained at such time from an unaffiliated party; 

(9) issuances or sales of Capital Stock (other than Disqualified Stock or Designated Preferred Stock) of Holdings’ or
options, warrants or other rights to acquire such Capital Stock and the granting of registration and other customary rights in connection therewith or any contribution to capital of Holdings or any Restricted Subsidiary;

(12) any purchases by Holdings’ Affiliates of Indebtedness or Disqualified Stock of Holdings or any Restricted Subsidiary

not Holdings’ Affiliates; and 

  
 -86-

 (7) that Holders whose Notes are being purchased only in part will be issued new
Notes and such new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered (with the unpurchased portion of the Notes required to be equal to at least $2,000 or any integral multiple of $1,000 in excess of
$2,000); 
 (8) if such notice is delivered prior to the occurrence of a Change of Control, stating that the Change of
Control Offer is conditional on the occurrence of such Change of Control; and 
 (9) the other instructions, as determined by
the Issuer, consistent with this Section 3.9, that a Holder must follow. 
 The Paying Agent will promptly deliver to each
Holder of the Notes tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and send (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Issuer will publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Payment Date. Any Change of Control Offer shall comply with the Applicable Procedures. 

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued
and unpaid interest will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business (New York City time) on such record date. 

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

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

 (2) deposit by 10:00 a.m. (New York City time) with the Paying Agent an amount (in United States Dollars in immediately
available funds) equal to the aggregate Change of Control Payment in respect of all Notes or portions thereof so tendered, and 

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officer’s
Certificate to the Trustee stating that such Notes or portions thereof have been tendered to and purchased by the Issuer and directing the Trustee to cancel such Notes. 

(c) The Issuer will not be required to make a Change of Control Offer following a Change of Control if (1) a third party makes the Change
of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under
such Change of Control Offer or (2) a notice of redemption of all outstanding Notes has been given pursuant to Section 5.7, unless and until there is a default in the payment of the redemption price on the applicable redemption date
or the redemption is not consummated 

  
 -88- 

 
for any reason on or before the 60th day after such Change of Control. Notwithstanding anything to the contrary in this Section 3.9, a Change of Control Offer may be made in advance
of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. 

(d) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a
Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described in this Section 3.9, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer
or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice to the Holders with a copy to the Trustee, given not more than 30 days following such purchase pursuant to the Change of Control Offer
described above, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to but not including the redemption date. 

(e) The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict
with the provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 

SECTION 3.10. Reports. 

(a) Whether or not required by the SEC, so long as any Notes are outstanding, Holdings shall (i) file electronically with the SEC through
the SEC’s Electronic Data Gathering, Analysis, and Retrieval System (“EDGAR”) or any successor system or (ii) otherwise furnish to the Trustee and the Holders: 

(1) within the time period then in effect under the rules and regulations of the Exchange Act with respect to the filing of a
Form 10-K for a non-accelerated filer, all information that would be required to be contained in an annual report on Form 10-K, or any successor or comparable form, filed with the SEC, including a “Management’s discussion and analysis
of financial condition and results of operations” and a report on the annual financial statements by Holdings’ independent registered public accounting firm; 

(2) within the time period then in effect under the rules and regulations of the Exchange Act with respect to the filing of a
Form 10-Q for a non-accelerated filer, all information that would be required to be contained in a quarterly report on Form 10-Q, or any successor or comparable form, filed with the SEC, including a
“Management’s discussion and analysis of financial condition and results of operations”; and 
 (3) within the
time period then in effect under the rules and regulations of the Exchange Act with respect to the filing of a Form 8-K after the occurrence of each event that would be required to be reported in a current report on Form 8-K, all information
that would be required to be contained in a current report on Form 8-K, or any successor or comparable form, filed with the SEC; 

  
 -89- 

 in each case, in a manner that complies in all material respects with the requirements specified in such form. At
any time that any of Holdings’ Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by this Section 3.10 shall include a reasonably detailed presentation, either on the face of the
financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of Holdings and its Restricted
Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Issuer; provided, however, that such reasonably detailed presentation shall not be required if the total assets of all
Unrestricted Subsidiaries are less than 5.0% of Holdings’ Total Assets. Promptly after filing (or, if applicable, furnishing to the Trustee and the Holders) information pursuant to the immediately preceding paragraph, Holdings shall also post
copies of such information required by the immediately preceding paragraph on its public website. To the extent any such information is not so filed or furnished, as applicable, within the time periods specified above and such information is
subsequently filed or furnished, as applicable, Holdings will be deemed to have satisfied its obligations with respect thereto at such time and any Default or Event of Default with respect thereto shall be deemed to have been cured at such time;
provided that such cure shall not otherwise affect the rights of the Holders under Section 6.1, Section 6.2 or otherwise in Article VI if Holders of at least 30% in principal amount of the then total
outstanding Notes have declared the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately and such declaration shall not have been rescinded or cancelled prior to such cure. In addition, to the extent not
satisfied by the foregoing, the Issuer will agree that, for so long as any Notes are outstanding, it will furnish to 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. 
 (b) Unless Holdings is otherwise obligated to do so under the Exchange Act or the rules
and regulations promulgated by the SEC thereunder, such reports referred to in Sections 3.10(a)(1), (2) and (3) will not be required: 

(1) to comply with Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 and 308 of
Regulation S-K promulgated by the SEC; 
 (2) to contain the separate financial information for Guarantors as contemplated by
Rule 3-10 of Regulation S-X or any financial statements of unconsolidated subsidiaries or 50% or less owned persons as contemplated by Rule 3-09 of Regulation S-X or any schedules required by Regulation
S-X, or in each case any successor provisions (it being understood however that Holdings will be required to furnish summary financial information with respect to the Guarantors and Non-Guarantors on a basis substantially consistent with the
financial information presented in the first and second sentences of the second paragraph under “Description of the Notes—Guarantees” in the Offering Circular); and 

(3) to comply with Regulation G under the Exchange Act or Item 10(e) of Regulation S-K with respect to any non-GAAP
financial measures contained therein. 

  
 -90- 

 (c) Notwithstanding any other provision of this Indenture, the sole remedy for an Event of
Default relating to the failure to comply with the reporting obligations set forth in this Section 3.10, for the 270 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional
interest on the principal amount of the Notes at a rate equal to 0.50% per annum. This additional interest shall be payable in the same manner and subject to the same terms as other interest payable under this Indenture. This additional
interest will accrue on all outstanding Notes from and including the date on which an Event of Default relating to a failure to comply with the reporting obligations described in Section 3.10(a) first occurs to, but excluding, the 270th
day thereafter (or such earlier date on which the Event of Default relating to such reporting obligations is cured or waived). If the Event of Default resulting from such failure to comply with the reporting obligations is continuing on such 270th
day, such additional interest will cease to accrue and the Notes will be subject to the other remedies provided under Article VI. If additional interest is payable on the Notes, the Issuer shall provide an Officer’s Certificate to
the Trustee on or before the record date for each Interest Payment Date such additional interest is payable setting forth the accrual period and the amount of such additional interest in reasonable detail. The Trustee may provide a copy of such
Officer’s Certificate received from the Issuer relating to additional interest to any Holder upon request. Unless and until a Trust Officer of the Trustee receives at the Corporate Trust Office such Officer’s Certificate, the Trustee may
assume without inquiry that no such additional interest is payable. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether any additional interest is payable, or with respect to the nature, extent,
or calculation of the amount of any additional interest owed, or with respect to the method employed in such calculation of any additional interest. If the Issuer has paid additional interest directly to the Holders entitled to it, the Issuer shall
deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment in reasonable detail. 
 (d) Holdings
will also hold quarterly conference calls for the Holders to discuss financial information for the previous quarter (it being understood that such quarterly conference call may be the same conference call as with Holdings’ equity investors and
analysts). The conference call will be following the last day of each fiscal quarter of Holdings and not later than ten (10) Business Days from the time Holdings files (or, if applicable, furnishes) the applicable financial information in
respect of such fiscal quarter as set forth in Section 3.10(a). No fewer than two (2) days prior to the conference call, Holdings will issue a press release announcing the time and date of such conference call and providing
instructions for Holders, securities analysts and prospective investors to obtain access to such call. The Trustee has no duty to participate in or monitor any conference calls required by this Section 3.10(d). The Trustee will not be
deemed to have received notice of any such conference calls unless notice is provided by the Issuer to the Trustee in writing. 
 (e)
Delivery of reports, information and documents under this Section 3.10 to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute actual or constructive notice of any information
contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s
Certificates). The Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the EDGAR filing system (or its successor) or whether or not postings to any website have
occurred. 

  
 -91- 

 SECTION 3.11. Maintenance of Office or Agency. 

The Issuer shall maintain an office or agency where the Notes will be payable at the office or agency of the Issuer maintained for such purpose
and where, if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be delivered. The Corporate Trust Office of the
Trustee, which initially shall be located at 1100 N. Market Street, Wilmington, DE 19890, Attention: Capital Markets & Agency Services, shall be such office or agency of the Issuer unless the Issuer shall designate and maintain some other
office or agency for one or more of such purposes. The Issuer will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuer shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee, and the Issuer hereby appoints the Trustee as its agent to receive all such
presentations and surrenders. 
 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 any such designation. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any
such other office or agency. 
 SECTION 3.12. Corporate Existence. Except as otherwise permitted by Article IV, each of
Holdings and the Issuer will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each Restricted Subsidiary
and the rights (charter and statutory), licenses and franchises of Holdings, the Issuer and each Restricted Subsidiary; provided, however, that each of Holdings and the Issuer shall not be required to preserve any such right, license
or franchise or the corporate, partnership, limited liability company or other existence of any Restricted Subsidiary of the Issuer if the respective Board of Directors or, with respect to a Restricted Subsidiary of the Issuer that is not a
Significant Subsidiary (or group of Restricted Subsidiaries that taken together would not be a Significant Subsidiary), senior management of Holdings determines that the preservation thereof is no longer desirable in the conduct of the business of
Holdings and each of its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not, and will not be, disadvantageous in any material respect to the Holders. 

SECTION 3.13. Payment of Taxes. Holdings shall pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, all material taxes, assessments and governmental charges levied or imposed upon Holdings or any Subsidiary thereof; provided, however, that Holdings shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of
management of Holdings), are being maintained in accordance with GAAP or where the failure to effect such payment will not be disadvantageous in any material respect to the Holders. 

  
 -92- 

 SECTION 3.14. Compliance Certificate. The Issuer shall deliver to the Trustee within
120 days after the end of each fiscal year of the Issuer an Officer’s Certificate that need not comply with the requirements set forth in Section 12.5, signed by the Chief Executive Officer, Chief Financial Officer or the
Treasurer of the Issuer, stating that in the course of the performance by the signer of his or her duties as an Officer of the Issuer he or she would normally have knowledge of any Default or Event of Default and whether or not the signer knows of
any Default or Event of Default that occurred during the previous fiscal year; provided that no such Officer’s Certificate shall be required for any fiscal year ended prior to the Issue Date. If such Officer does have such knowledge, the
certificate shall describe the Default or Event of Default, its status and the action the Issuer is taking or proposes to take with respect thereto. 

SECTION 3.15. [Reserved]. 

SECTION 3.16. Statement by Officers as to Default. The Issuer shall deliver to the Trustee, within 30 days after the occurrence
thereof, written notice of any events of which it is aware which would constitute a Default or Event of Default, their status and what action the Issuer is taking or proposes to take in respect thereof. 

SECTION 3.17. Suspension of Certain Covenants on Achievement of Investment Grade Status. 

(a) Following the first day that: (1) the Notes have achieved Investment Grade Status; and (2) no Default or Event of Default has
occurred and is continuing under this Indenture, then, beginning on that day and continuing until the Reversion Date (as defined below), Holdings and its Restricted Subsidiaries will not be subject to Sections 3.2, 3.3,
3.4, 3.5, 3.7, 3.8 and 4.1(a)(3) (collectively, the “Suspended Covenants”). 
 (b) If at
any time the Notes cease to have such Investment Grade Status or if a Default or Event of Default occurs and is continuing, then the Suspended Covenants will thereafter be reinstated as if such covenants had never been suspended (the
“Reversion Date”) and be applicable pursuant to the terms of this Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of this Indenture), unless and until the Notes
subsequently attain Investment Grade Status and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Status and no Default or
Event of Default is in existence); provided, however, that no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Notes or the Note Guarantees with respect to the Suspended Covenants based
on, and none of Holdings or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising
prior to the Reversion Date (in each case to the extent such actions or events are permitted at such time, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such
period). The period of time between the date of suspension of the covenants and the Reversion Date is referred to as the “Suspension Period.” 

  
 -93- 

 (c) On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be
classified to have been Incurred pursuant to Section 3.2(a) or one of the clauses set forth in Section 3.2(b) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after
giving effect to the Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to Sections 3.2(a) or (b), such
Indebtedness will be deemed to have been outstanding on the Issue Date so that it is classified as permitted under Section 3.2(b)(4)(ii). Calculations made after the Reversion Date of the amount available to be made as Restricted
Payments under Section 3.3 will be made as though Section 3.3 had been in effect since the Issue Date and throughout the Suspension Period; provided, however, that, no Subsidiaries may be designated as
Unrestricted Subsidiaries during the Suspension Period, unless such designation would have complied with Section 3.3 as if such Section would have been in effect during such period. Accordingly, Restricted Payments made during the
Suspension Period will reduce the amount available to be made as Restricted Payments under Section 3.3(a). 
 (d) The Trustee
shall have no obligation to independently determine or verify if circumstances set forth in Section 3.17(a), Section 3.17(b) or Section 3.17(c) have occurred or notify the Holders (or beneficial owners of Notes)
of the continuance and termination of any Suspension Period. 
 (e) The Issuer shall reasonably promptly provide an Officer’s
Certificate to the Trustee indicating the occurrence of any Suspended Covenants or the Reversion Date. The Trustee may provide a copy of such Officer’s Certificate to any Holders (or beneficial owners of Notes) upon request. 

SECTION 3.18. Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of Holdings may designate any Restricted Subsidiary of the Issuer to be an Unrestricted Subsidiary if no Default or
Event of Default would be in existence following such designation and subject to the requirements set forth in the definition of “Unrestricted Subsidiary”. If a Restricted Subsidiary of the Issuer is designated as an Unrestricted
Subsidiary, the aggregate fair market value of all outstanding Investments owned by Holdings and its Restricted Subsidiaries in the Subsidiary of the Issuer designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the
time of the designation and will reduce the amount available for Restricted Payments under Section 3.3 or under one or more clauses of the definition of Permitted Investments, as determined by Holdings. That designation will only be
permitted if the Investment would be permitted at that time and if the Restricted Subsidiary of the Issuer otherwise meets the definition of an Unrestricted Subsidiary. 

(b) Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a
resolution of the Board of Directors of Holdings giving effect to such designation and an Officer’s Certificate certifying that such designation complies with the preceding conditions and was permitted by Section 3.3. If, at any
time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of 

  
 -94- 

 
this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Issuer as of such date and, if such Indebtedness is not permitted to be
incurred as of such date under Section 3.2, the Issuer will be in default of Section 3.2. 
 (c) The Board of
Directors of Holdings may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Issuer; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the
Issuer of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 3.2 calculated on a pro forma basis as if such designation had
occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such designation. Any such designation by the Board of Directors of Holdings shall be evidenced to the Trustee
by filing with the Trustee a certified copy of a resolution of the Board of Directors of Holdings giving effect to such designation and an Officer’s Certificate certifying that such designation complies with the preceding conditions. 

(d) Notwithstanding anything in this Indenture to the contrary, and for the avoidance of doubt, neither Holdings nor the Issuer may be, or may
be designated as, an Unrestricted Subsidiary. 
 SECTION 3.19. Limitation on Sale and Leaseback Transactions. 

(a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction with respect
to any property unless: 
 (1) Holdings or such Restricted Subsidiary would be entitled to (i) Incur Indebtedness in an
amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to Section 3.2 and (ii) create a Lien on such property securing such Attributable Debt without equally and ratably securing the Notes
pursuant to Section 3.6. 
 (2) the net proceeds received by Holdings or such Restricted Subsidiary in connection
with such Sale and Leaseback Transaction are at least equal to the fair market value of such property; and 
 (3) Holdings or
such Restricted Subsidiary applies the proceeds of such transaction in compliance with Section 3.5. 

  
 -95- 

 ARTICLE IV 

SUCCESSOR ISSUER; SUCCESSOR PERSON 

SECTION 4.1. Merger and Consolidation. 

(a) The Issuer shall not consolidate with or merge with or into or convey, transfer or lease all or substantially all its assets, in one or
more related transactions, to any Person, unless: 
 (1) the resulting, surviving or transferee Person (the
“Successor Company”) will be a Person organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and the Successor Company (if not the Issuer) will expressly
assume, by supplemental indenture, executed and delivered to the Trustee, all the obligations of the Issuer under the Notes and this Indenture and if such Successor Company is not a corporation, a co-obligor of the Notes that is a corporation
organized or existing under such laws shall be appointed pursuant to such supplemental indenture; 
 (2) immediately after
giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the applicable Successor Company or any Subsidiary of the applicable Successor Company as a result of such transaction as having been Incurred by the
applicable Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be continuing; 

(3) immediately after giving effect to such transaction, either (i) the applicable Successor Company would be able to
Incur at least an additional $1.00 of Indebtedness pursuant to Section 3.2(a) or (ii) the Fixed Charge Coverage Ratio of Holdings and its Restricted Subsidiaries would not be lower than it was immediately prior to giving effect to
such transaction; and 
 (4) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture and an Opinion of Counsel stating that such supplemental indenture (if any) has been duly authorized, executed and
delivered and is a legal, valid and binding agreement enforceable against the applicable Successor Company (in each case, in form satisfactory to the Trustee); provided that in giving an Opinion of Counsel, counsel may rely on an
Officer’s Certificate as to any matters of fact, including as to satisfaction of Sections 4.1(a)(2) and (3). 
 (b)
For purposes of this Section 4.1, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Issuer, which properties and assets, if
held by the Issuer instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Issuer on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and
assets of the Issuer. 
 (c) The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the
Issuer under the Note Documents, but in the case of a lease of all or substantially all its assets, the predecessor company will not be released from its obligations under the Note Documents. 

(d) Notwithstanding Sections 4.1(a)(2), (3) and (4) (which do not apply to transactions referred to in
this sentence), any Restricted Subsidiary of the Issuer may consolidate or otherwise combine with, merge into or transfer all or part of its properties and assets to the Issuer. Notwithstanding Sections 4.1(a)(2) and
(3) (which do not apply to the transactions referred to in this sentence), the Issuer may consolidate or otherwise combine with or merge into an Affiliate incorporated or organized for the purpose of changing the legal domicile of the
Issuer, reincorporating the Issuer in another jurisdiction, or changing the legal form of the Issuer. 

  
 -96-

this Indenture; and 
 (ii) immediately after giving effect to the transaction, no Default or Event of Default has occurred
and is continuing. 
 (f) No Subsidiary Guarantor may: 

(1) consolidate with or merge with or into any Person, or 

(2) sell, convey, transfer or dispose of, all or substantially all its assets, in one transaction or a series of related
transactions, to any Person, or 
 (3) permit any Person to merge with or into the Subsidiary Guarantor, unless: 

(i) the other Person is the Issuer or a Subsidiary Guarantor or becomes a Subsidiary Guarantor concurrently with the
transaction; or 
 (ii) (A) either (x) a Subsidiary Guarantor is the surviving Person or (y) the resulting,
surviving or transferee Person is a Person organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and expressly assumes by supplemental indenture all of the obligations of
the Subsidiary Guarantor under its Note Guarantee and under this Indenture; and 
 (B) immediately after giving effect to
the transaction, no Default or Event of Default has occurred and is continuing; or

 ARTICLE V 

REDEMPTION OF NOTES 

SECTION 5.1. Notices to Trustee. If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of
Section 5.7, it must furnish to the Trustee, at least five (5) Business Days prior to the issuance of the notice of redemption to the Holders (unless a shorter period shall be satisfactory to the Trustee), an Officer’s
Certificate setting forth: 
 (1) the clause of this Indenture pursuant to which the redemption shall occur, that such
redemption complies with this Indenture and whether the redemption will be subject to any conditions; 
 (2) the redemption
date; 
 (3) the principal amount of Notes to be redeemed; and 

(4) the redemption price. 

Any optional redemption referenced in such Officer’s Certificate may be cancelled by the Issuer at any time prior to notice of redemption
being sent to any Holder. If the redemption price is not known at the time such notice is to be given, the actual redemption price calculated as described in the terms of the Notes will be set forth in an Officer’s Certificate delivered to the
Trustee no later than two (2) Business Days prior to the redemption date. 
 SECTION 5.2. Selection of Notes to Be Redeemed or
Purchased. If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes for redemption in compliance with the requirements of the principal securities exchange, if any, on which the Notes are listed, as
certified to the Trustee by the Issuer, and in compliance with the Applicable Procedures, or if the Notes are not so listed or such exchange prescribes no method of selection and the Notes are not held through DTC or DTC prescribes no method of
selection, in accordance with the Trustee’s procedures, subject to adjustments so that no Note in an unauthorized denomination is redeemed in part; provided, however, that no Note of $2,000 in aggregate principal amount or less
will be redeemed in part. 
 SECTION 5.3. Notice of Redemption. 

(a) Notices of redemption will be delivered electronically or mailed by first-class mail at least 30 days but not more than 60 days
before the redemption date to each Holder of Notes to be redeemed at the address of such Holder appearing in the security register or otherwise in accordance with the Applicable Procedures, except that redemption notices may be delivered
electronically or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII or XI. 

The notice will identify the Notes (including the CUSIP or ISIN number) to be redeemed and will state: 

(1) the redemption date; 

  
 -98- 

 (2) the redemption price;

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 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 called for redemption cease 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) if such redemption or notice is subject to satisfaction of one or more
conditions precedent, that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any
or all such conditions shall not have been satisfied by 3:00 p.m. (New York City time) on the Business Day prior to the redemption date (or by 3:00 p.m. (New York City time) on the Business Day prior to the redemption date so delayed); and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number listed in such notice or
printed on the Notes. 
 (b) If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the
portion of the principal amount thereof to be redeemed, in which case the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon cancellation of the original Note. In the case of a Global Note, an appropriate
notation shall be made on such Note to decrease the principal amount thereof to an amount equal to the unredeemed portion thereof. Subject to the terms of the applicable redemption notice (including any conditions contained therein), Notes called
for redemption become due on the date fixed for redemption. On and after the redemption date, unless the Issuer defaults in the payment of the redemption price, interest ceases to accrue on Notes or portions of them called for redemption. 

(c) For Notes which are represented by global certificates held on behalf of DTC, notices may be given by delivery of the relevant notices to
DTC, in accordance with their procedures for communication to entitled account holders in substitution for the aforesaid electronic delivery or first- class mailing. 

(d) At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense.
In such event, the Issuer shall provide the Trustee 

  
 -99- 

 
with an Officer’s Certificate with the notice to be given as an exhibit thereto containing the information required by this Section 5.3 at least five (5) Business Days prior
to the date on which the Issuer instructs the Trustee to send the notice (or such shorter period as the Trustee may agree). 
 SECTION 5.4.
Effect of Notice of Redemption. Subject to the following sentence, once notice of redemption is sent in accordance with Section 5.3, Notes called for redemption become irrevocably due and payable on the redemption date at the
redemption price. Any optional redemption may, at the Issuer’s option and discretion, be subject to one or more conditions precedent, including, but not limited to, completion of an Equity Offering in the case of a redemption related to an
Equity Offering. If any such condition precedent has not been satisfied, the Issuer will provide notice to the Holders and the Trustee not later than 3:00 p.m. New York City time on the Business Day prior to the redemption date that such condition
precedent has not been satisfied and will specify in such notice that the notice of redemption is either rescinded or delayed and that either the redemption shall not occur or shall be delayed subject to the satisfaction of such condition precedent.

 SECTION 5.5. Deposit of Redemption or Purchase Price. Prior to 10:00 a.m., New York City time, on the redemption or purchase date,
the Issuer will deposit with the Trustee or with the Paying Agent money (in United States Dollars in immediately available funds) sufficient to pay the redemption or purchase price of and accrued interest, if any, on, all Notes to be redeemed or
purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and
accrued interest, if any, on, all Notes to be redeemed or purchased. 
 If the Issuer complies with the provisions of the preceding
paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after 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 (New York City time) on such record date, and no other interest will be payable to
Holders whose Notes will be subject to redemption by the Issuer. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in
Section 3.1. 
 SECTION 5.6. Notes Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased
in part, the Issuer will issue and, upon receipt of an Issuer Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered;
provided, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

 (1) in each case the
redemption takes place not later than 90 days after the closing of the related Equity Offering, and

5.6.

with respect to the Notes; provided however, that under certain circumstances, the Issuer may be required to offer to purchase Notes under Section 3.5 and Section 3.9. The Issuer may at any time and from time to time
purchase Notes in the open market or otherwise.

Restricted Subsidiary whether such Indebtedness or Guarantee now exists, or is created after the date hereof, which default: 

(A) is caused by a failure to pay principal of such Indebtedness, at its stated final maturity (after giving effect to any
applicable grace periods) provided in such Indebtedness; or 
 (B) results in the acceleration of such Indebtedness prior to
its stated final maturity;

other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $100,000,000 or more; 

(6) Holdings, the Issuer or a Significant Subsidiary or group of Restricted Subsidiaries that together (as of the latest

 (9) the Note Guarantee of Holdings or of any Subsidiary Guarantor that is a
Significant Subsidiary ceases to be in full force and effect (other than in accordance with the terms of this Indenture) or shall be held in any judicial proceeding to be unenforceable or invalid or Holdings or any Subsidiary Guarantor that is a
Significant Subsidiary (or any Person acting on behalf of Holdings or such Subsidiary Guarantor) denies or disaffirms Holdings’ or such Subsidiary Guarantor’s obligations under its Note Guarantee. 

(b) Notwithstanding the foregoing, a Default under Section 6.1(a)(4) will not constitute an Event of Default until the Trustee or
the Holders of 30% in principal amount of the outstanding Notes notify the Issuer (and the Trustee if given by the Holders) of the Default and the Issuer does not cure such Default within the time specified in Section 6.1(a)(4) after
receipt of such notice. 
 SECTION 6.2. Acceleration. 

(a) If an Event of Default (other than an Event of Default described in Section 6.1(a)(6) or (7)) occurs and is
continuing, the Trustee by written notice to the Issuer (or the Holders of at least 30% in principal amount of the outstanding Notes by written notice to the Issuer and the Trustee), may declare the principal of and accrued and unpaid interest on
all the Notes to be due and payable. Upon such a declaration, such principal and accrued and unpaid interest will be due and payable immediately. 

(b) In the event of a declaration of acceleration of the Notes because an Event of Default described in Section 6.1(a)(5) has
occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if: 
 (1) the event
of default or payment default triggering such Event of Default pursuant to Section 6.1(a)(5) shall be remedied or cured, or waived by the holders of the Indebtedness, or the Indebtedness that gave rise to such Event of Default shall have
been discharged in full, in each case, within 30 days after the declaration of acceleration with respect thereto; 
 (2)
the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and 

(3) all existing Events of Default, except nonpayment of principal or interest on the Notes that became due solely because of
the acceleration of the Notes, have been cured or waived. 
 (c) If an Event of Default described in Section 6.1(a)(6) or
(7) occurs, the principal of, and accrued and unpaid interest on, all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. 

  
 -104- 

 (d) (i) If a Default for a failure to report, or for a failure to deliver a required
certificate in connection with, another Default (the “Initial Default”) occurs, then at the time such Initial Default is cured, such Default for a failure to report or failure to deliver a required certificate in connection with
another Default that resulted solely because of that Initial Default shall also be cured without any further action and (ii) any Default or Event of Default for the failure to comply with the time periods prescribed under
Section 3.10, or otherwise to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the delivery of any such report required by Section 3.10 or such notice or
certificate, as applicable, even though such delivery is not within the prescribed period specified herein. 
 SECTION 6.3. Other
Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the
Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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. No remedy is exclusive of any other remedy. All available remedies are cumulative. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings, the Issuer, the Guarantors, the Trustee
and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted. 

SECTION 6.4. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written
notice to the Trustee may, on behalf of all of the Holders, (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), all past or existing
Defaults or Events of Default and its consequences under this Indenture except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest, on a Note or (ii) a Default or Event of Default in
respect of a provision that under Section 9.2(b) cannot be amended, supplemented or waived without the consent of each Holder affected and (b) rescind any acceleration with respect to the Notes and its consequences if (1) such
rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (2) all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely
because of the acceleration, (3) to the extent the payment of such interest is lawful, interest on overdue installments of interest, premium, if any, and overdue principal, which has become due otherwise than by such declaration of
acceleration, has been paid and (4) in the event of the cure or waiver of an Event of Default of the type described in clause (4) of Section 6.1(a), the Trustee shall have received an Officer’s Certificate and an
Opinion of Counsel stating that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. When a Default or Event of Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right. 

  
 -105- 

 SECTION 6.5. Control by Majority. The Holders of a majority in principal amount of the
outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or the Notes or, subject to Sections 7.1 and 7.2, that the Trustee determines is unduly prejudicial to the rights of other Holders (it being understood that the Trustee does not have an
affirmative duty to ascertain whether or not any actions are unduly prejudicial to such other Holders) or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. Prior to taking any such action hereunder, the Trustee shall be entitled to indemnification or security satisfactory to it against all fees, losses and expenses (including attorney’s
fees and expenses) that may be caused by taking or not taking such action. 
 SECTION 6.6. Limitation on Suits. If an Event of
Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or
security satisfactory to the Trustee against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or the
Notes unless: 
 (1) such Holder has previously given the Trustee written notice that an Event of Default is continuing; 

(2) Holders of at least 30% in principal amount of the outstanding Notes have requested in writing the Trustee to pursue the
remedy; 
 (3) such Holders have offered in writing the Trustee security or indemnity satisfactory to the Trustee against any
loss, liability or expense; 
 (4) the Trustee has not complied with such request within 60 days after the receipt of
the written request and the offer of security or indemnity; and 
 (5) the Holders of a majority in principal amount of the
outstanding Notes have not given the Trustee a written direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 

SECTION 6.7. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including, without
limitation, Section 6.6), the right of any Holder to receive payment of principal of, premium, if any, or interest, if any, on the Notes held by such Holder, on or after the respective due dates expressed or provided for in the Notes, 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. 

  
 -106- 

 SECTION 6.8. Collection Suit by Trustee. If an Event of Default specified in
Section 6.1(a)(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section 7.7. 
 SECTION 6.9. Trustee May File Proofs of
Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to Holdings, the Issuer, its Subsidiaries or its or their respective creditors or properties and, unless prohibited by law or applicable
regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding, shall be unpaid 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. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 SECTION 6.10. Priorities. 

(a) If the Trustee collects any money or property pursuant to this Article VI it shall pay out the money or property in the
following order: 
 FIRST: to the Trustee for amounts due to it under Section 7.7; 

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

THIRD: to the Issuer, or to the extent the Trustee collects any amount from any Guarantor, to such Guarantor. 

  
 -107- 

 (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to
this Section 6.10. At least fifteen (15) days before such record date, the Issuer shall send or cause to be sent to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. 

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, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees and expenses, 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 does not apply to a
suit by the Trustee, a suit by the Issuer, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Notes.

provided to a Trust Officer as described in Section 7.2(f), the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or
use under the circumstances in the conduct of such person’s own affairs.

opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture or the Notes,
as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 
 (c) The
Trustee may not be relieved from liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that:

subject to clauses (a), (b) and (c) of this Section 7.1.

resolution, certificate, statement, instrument, report, notice, request, direction, consent, order, bond, debenture, coupon or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine, during business hours and upon reasonable notice, the books, records and premises of Holdings and
the Restricted Subsidiaries, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 

  
 -110- 

 (m) 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 or the Notes. 

(n) In no event shall the Trustee be liable to any Person for special, punitive, indirect, consequential or incidental loss or damage of any
kind whatsoever (including, but not limited to, lost profits), even if the Trustee has been advised of the likelihood of such loss or damage. 

(o) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if
signed by one Officer of the Issuer or sufficiently evidenced by an Officer’s Certificate or by an Issuer Order, and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. 

(p) The Trustee shall have the right, but shall not be required, to rely upon and comply with instructions and directions sent by e-mail,
facsimile and other similar unsecured electronic methods by persons believed by the Trustee to be authorized to give instructions and directions on behalf of the Issuer, the Guarantors or any Person. The Trustee shall have no duty or obligation to
verify or confirm that the Person who sent such instructions or directions is, in fact, a Person authorized to give instructions or directions on behalf of the Issuer or Guarantors; and the Trustee shall have no liability for any losses,
liabilities, costs or expenses incurred or sustained by the Issuer or Guarantors as a result of such reliance upon or compliance with such instructions or directions. The Issuer or Guarantors agree to assume all risks arising out of the use of such
electronic methods to submit instructions and directions to the Trustee, including, without limitation, the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. 

SECTION 7.3. 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, Guarantors or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee
must comply with Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to engage in transactions with the Issuer; provided, however, that if the Trustee acquires any conflicting interest as defined by
the Trust Indenture Act, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest or (ii) resign. 

SECTION 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture, the Notes or the Note Guarantees, shall not be accountable for the Issuer’s use of the proceeds from the sale of the Notes, shall not be responsible for the use or application of any money received by any Paying
Agent (other than the Trustee to the extent the Trustee is the Paying Agent) or any money paid to the Issuer or upon the Issuer’s direction pursuant to the terms of this Indenture and shall not be responsible for any statement of the Issuer in
this Indenture, in the Offering Circular or in any document issued in connection with the sale of the Notes or in the Notes (other than, in the case of the Trustee, the Trustee’s certificate of authentication). 

SECTION 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and the Trustee is informed in writing of
such occurrence by the Issuer, the Trustee 

  
 -111- 

 
must give notice of the Default or Event of Default to the Holders within 60 days after being notified by the Issuer. Except in the case of a Default or Event of Default in payment of
principal of, or premium, if any, or interest on any Note, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interests of the Holders. 

SECTION 7.6. Reports by Trustee to Holders. Within 60 days after each December 31 beginning December 31, 2015, the
Trustee shall mail to each Holder a brief report dated as of such December 31 that complies with Section 313(a) of the Trust Indenture Act if and to the extent required thereby. The Trustee also shall comply with Section 313(c) of the
Trust Indenture Act. 
 A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange (if
any) on which the Notes are listed. The Issuer agrees to notify the Trustee promptly in writing whenever the Notes become listed on any stock exchange and of any delisting thereof and the Trustee shall comply with Section 313(d) of the Trust
Indenture Act. 
 SECTION 7.7. Compensation and Indemnity. The Issuer and Guarantors shall, jointly and severally, pay to the Trustee
from time to time compensation for its services hereunder and under the Notes as the Issuer and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Issuer and Guarantors shall, jointly and severally, reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including, but not limited to, costs of collection, costs of preparing
reports, certificates and other documents, costs of preparation and mailing or sending of notices to Holders. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the agents, counsel, accountants and
experts of the Trustee. The Issuer and the Guarantors shall jointly and severally indemnify the Trustee against any and all fees, loss, liability, damages, claims or expense, including taxes (other than taxes based upon the income of the Trustee)
(including reasonable attorneys’ and agents’ fees and expenses) incurred by it without willful misconduct or gross negligence, as determined by a final non-appealable order of a court of competent jurisdiction, on its part in connection
with the administration of this trust and the performance of its duties hereunder and under the Notes, including the fees, costs and expenses of enforcing this Indenture (including this Section 7.7), the Note Guarantees and the Notes and
of defending itself against any claims (whether asserted by any Holder, the Issuer, the Guarantors or otherwise). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity of which it has received written notice.
Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee shall provide reasonable cooperation at the Issuer’s expense in the defense. The Trustee
may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer and the Guarantors need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. All
indemnifications and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, custodians, successors and assigns. 

To secure the Issuer’s and Guarantors’ payment obligations in this Section 7.7, the Trustee shall have a lien prior to
the Notes on all money or property held or collected by the 

  
 -112- 

 
Trustee. Such lien shall survive the satisfaction and discharge of this Indenture. The Trustee’s respective right to receive payment of any amounts due under this Section 7.7 shall
not be subordinate to any other liability or Indebtedness of the Issuer. 
 The Issuer’s payment obligations pursuant
to this Section 7.7 shall survive the payment of the Notes and the discharge of this Indenture and the resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee incurs fees, expenses or renders services after the occurrence of a Default specified in Section 6.1(a)(6) or (a)(7), the fees and expenses (including the reasonable fees and expenses of its counsel) are intended to constitute
expenses of administration under any Bankruptcy Law. “Trustee” for the purposes of this Section 7.7 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person
employed to act hereunder; provided, however, that the gross negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

SECTION 7.8. Replacement of Trustee. The Trustee may resign at any time by so notifying the Issuer in writing not less than
30 days prior to the effective date of such resignation. The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the removed Trustee in writing not less than 30 days prior to the effective date of
such removal and may appoint a successor Trustee with the Issuer’s written consent, which consent will not be unreasonably withheld. The Issuer shall remove the Trustee (and any Holder that has been a bona fide Holder for not less than six
months may petition any court for removal of the Trustee and appointment of a successor Trustee) if: 
 (1) the Trustee fails
to comply with Section 7.10; 
 (2) the Trustee is adjudged bankrupt or insolvent; 

(3) a receiver or other public officer takes charge of the Trustee or its property; 

(4) the Trustee otherwise becomes incapable of acting as trustee hereunder; or 

(5) the Trustee acquires a conflicting interest, as defined by the Trust Indenture Act. 

If the Trustee resigns or is removed by the Issuer (or a bona fide Holder described above) or by the Holders of a majority in principal amount
of the Notes and such Holders do not reasonably promptly appoint a successor Trustee as described in the preceding paragraph, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as
the retiring Trustee), the Issuer shall promptly appoint a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of
its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail or send a notice of its succession to Holders. The retiring Trustee shall, at the expense of the Issuer, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.7. 

  
 -113- 

 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or
is removed, the retiring Trustee or the Holders of at least 10% in principal amount of the Notes may petition, at the Issuer’s expense, any court of competent jurisdiction for the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under
Section 7.7 shall continue for the benefit of the retiring Trustee. The predecessor Trustee shall have no liability for any action or inaction of any successor Trustee. 

SECTION 7.9. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by
this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that
time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; provided that the right to adopt
the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall only apply to its successor or successors by merger, consolidation or conversion. 

SECTION 7.10. Eligibility; Disqualification. There will at all times be a Trustee hereunder that is a corporation organized and doing
business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a
combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition. 
 SECTION
7.11. Preferential Collection of Claims Against the Issuer. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee
who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated. 
 SECTION
7.12. Trustee’s Application for Instruction from the Issuer. Any application by the Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by
the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal
included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any Officer of the Issuer actually receives such application, unless any such Officer
shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the
action to be taken or omitted.

 ARTICLE VIII 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 8.1. Option to Effect Legal Defeasance or Covenant Defeasance; Defeasance. The Issuer may, at its option and at any time, elect
to have either Section 8.2 or Section 8.3 be applied to all outstanding Notes upon compliance with the conditions set forth in this Article VIII. 

SECTION 8.2. Legal Defeasance and Discharge. Upon the Issuer’s exercise under Section 8.1 of the option applicable to
this Section 8.2, the Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from their obligations with respect to all outstanding
Notes (including the Note Guarantees) on the date the conditions set forth in Section 8.4 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 (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 and
the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all of their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on written demand
of and at the expense of the Issuer, shall execute proper instruments acknowledging the same) and to have cured all then existing Events of Default, except for the following provisions which will survive until otherwise terminated or discharged
hereunder: 
 (1) the rights of Holders of Notes issued under this Indenture to receive payments in respect of the principal
of, premium, if any, and interest on the Notes when such payments are due solely out of the trust referred to in Section 8.4; 

(2) the Issuer’s obligations with respect to the Notes under Article II concerning issuing temporary Notes,
registration of such Notes, mutilated, destroyed, lost or stolen Notes and Section 3.11 concerning the maintenance of an office or agency for payment and money for security payments held in trust; 

(3) the rights, powers, trusts, duties, indemnities and immunities of the Trustee and the Issuer’s or Guarantors’
obligations in connection therewith; and 
 (4) this Article VIII with respect to provisions relating to Legal
Defeasance. 
 Subject to compliance with this Section 8.2, the Issuer may exercise its option under this
Section 8.2 notwithstanding the prior exercise of its option under Section 8.3. 
 SECTION 8.3. Covenant
Defeasance. Upon the Issuer’s exercise under Section 8.1 of the option applicable to this Section 8.3, the Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in
Section 8.4, be released from each of their obligations under the covenants contained in Section 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.14, 3.17,
3.18, 3.19 and Section 4.1 (except Section 4.1(a)(1) and (a)(2)) with respect to the outstanding Notes on and after the date of the conditions set forth in Section 8.4 are satisfied
(hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the 

  
 -115- 

 
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. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuer and the Guarantors may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1(a), but, except as specified in this Section 8.3, the remainder of this Indenture
and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.1 of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set
forth in Section 8.4, Sections 6.1(a)(3) (solely with respect to the defeased covenants listed above), 6.1(a)(4) (solely with respect to the defeased covenants listed above), 6.1(a)(5), 6.1(a)(6) (with
respect only to a Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that taken together would constitute a Significant Subsidiary), 6.1(a)(7) (with respect only to a Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that taken together would constitute a Significant Subsidiary) and 6.1(a)(8) shall not constitute Events of Default. In addition, upon the occurrence of Covenant Defeasance, the
Note Guarantees shall terminate as provided in Section 10.2 and, as a result, the Event of Default specified in Section 6.1(a)(9) shall cease to apply upon the occurrence of Covenant Defeasance. 

SECTION 8.4. Conditions to Legal or Covenant Defeasance. In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.2 or 8.3: 
 (1) the Issuer must irrevocably deposit in trust with the Trustee (the
“Defeasance Trust”), for the benefit of the Holders, cash in United States Dollars or U.S. Government Obligations or a combination thereof in such amounts as will be sufficient (without consideration of any reinvestment of
interest), in the opinion of an Independent Financial Advisor delivered to the Trustee, to pay the principal, premium, if any and interest due on the Notes on the stated maturity date or on the applicable redemption date, as the case may be, and the
Issuer must specify whether such Notes are being defeased to maturity or to a particular redemption date; 
 (2) in the case
of Legal Defeasance pursuant to Section 8.2, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that, subject to customary assumptions and exclusions: 

(i) the Issuer has received from, or there has been published by, the United States Internal Revenue Service a ruling; or 

(ii) since the issuance of the Initial Notes, there has been a change in the applicable U.S. federal income tax law 

in either case stating that, and based thereon such Opinion of Counsel in the United States shall confirm that, subject to customary assumptions and
exclusions, the Holders 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; 

  
 -116- 

 (3) in the case of Covenant Defeasance pursuant to Section 8.3, the
Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States stating that, subject to customary assumptions and exclusions, the Holders 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 Default or Event of Default (other than that resulting from borrowing funds to be applied to make such deposit and the
granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit; 
 (5) such
Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any Credit Facilities or any other material agreement or instrument (other than this Indenture) to which, the Issuer or any Guarantor
is a party or by which the Issuer or any Guarantor is bound; 
 (6) the Issuer shall have delivered to the Trustee an
Officer’s Certificate stating that the deposit was not made by the Issuer with the intent of defeating, hindering, delaying, defrauding or preferring any creditors of the Issuer; and 

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

SECTION 8.5. Deposited Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions. Subject to
Section 8.6, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”)
pursuant to Section 8.4 in respect of the outstanding Notes 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, 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 U.S. Government Obligations deposited pursuant to Section 8.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article VIII to the contrary, the Trustee
will deliver or pay to the Issuer from time to time upon the request of the Issuer any money or U.S. Government 

  
 -117- 

 
Obligations held by it as provided in Section 8.4 which, in the opinion of an Independent Financial Advisor in a written certification thereof delivered to the Trustee (which may be
the Independent Financial Advisor delivering the opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 SECTION 8.6. Repayment to the Issuer. Subject to the requirements of any applicable abandoned 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, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has
become due and payable shall be paid to the Issuer on its written request unless an abandoned property law designates another Person 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 unless an abandoned property law designates another Person, 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; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The Wall
Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Issuer. 
 SECTION 8.7. Reinstatement. If the Trustee or Paying Agent is unable to apply any
money or United States Dollars or U.S. Government Obligations in accordance with Section 8.2 or Section 8.3, 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 the Note Documents, the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.2
or Section 8.3 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or Section 8.3, 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 or
U.S. Government Obligations held by the Trustee or Paying Agent. 
 ARTICLE IX 

AMENDMENTS 
 SECTION 9.1.
Without Consent of Holders. Notwithstanding Section 9.2, without the consent of any Holder, the Issuer, the Trustee and the other parties thereto, as applicable, may amend or supplement any Note Documents and the Issuer may direct
the Trustee, and the Trustee will, enter into an amendment to any Note Document, to:

Act or any applicable securities law and (ii) such amendment does not adversely affect the rights of Holders to transfer Notes in any material respect. 

Subject to Section 9.2, upon the request of the Issuer accompanied by a Board Resolution authorizing the execution of any such
amendment or supplement to the applicable Note Document, and upon receipt by the Trustee of the documents described in Section 9.6 and Section 12.4, the Trustee will join with the Issuer and the Guarantors in the execution of
such amendment or supplement unless such amendment or supplement directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to,
enter into such amendment or supplement. 

  
 -119- 

 After an amendment or supplement under this Section 9.1 becomes effective, the Issuer
shall mail or otherwise deliver to Holders a notice briefly describing such amendment or supplement. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement under
this Section 9.1. 
 SECTION 9.2. With Consent of Holders. 

(a) Except as otherwise provided in this Section 9.2, the Note Documents may be amended, supplemented or otherwise modified with

Sections 6.4 and 6.7, any existing Default or Event of Default or compliance with any provisions thereof may be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding

Change of Control in accordance with Section 3.9 after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto; 

  
 -120- 

 (6) make any Note payable in currency other than that stated in such Note;

due dates therefor or to institute suit for the enforcement of any such payment on or with respect to such Holder’s Notes; 

(8) waive a Default or Event of Default with respect to the nonpayment of principal, premium or interest (except pursuant to a
rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

(9) make any change in the ranking of any Note that would adversely affect the Holders; 

(10) [Reserved]; 

(11) make any change to the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or premium, if any, or interest on the Notes; 
 (12) release any Guarantor from its
obligations under its Note Guarantee or under this Indenture, except in accordance with the express terms of this Indenture or such Note Guarantee; or 

(13) make any change to Section 9.2(a) or this Section 9.2(b). 

(c) The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment, supplement or
waiver of any Note Document. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. A consent to any amendment, supplement or waiver under this Indenture by any Holder of Notes given in connection
with a tender of such Holder’s Notes will not be rendered invalid by such tender. 
 (d) After an amendment, supplement or waiver under
this Section 9.2 becomes effective, the Issuer shall mail or send to Holders a notice briefly describing such amendment, supplement or waiver. The failure to give such notice to all Holders, or any defect therein, shall not impair or
affect the validity of an amendment, supplement or waiver. 
 (e) Neither the Issuer nor any Affiliate of the Issuer may, directly or
indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless
such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. 

SECTION 9.3. [Reserved]. 

  
 -121- 

 SECTION 9.4. Revocation and Effect of Consents and Waivers. 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 such Holder’s Note or portion of its Note if the Trustee receives written notice of revocation
before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or
take any other action described in this Section 9.4 or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at
such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such
record date. No such consent shall be valid or effective for more than 120 days after such record date. 
 SECTION 9.5. Notation on
or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Issuer
Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 

SECTION 9.6. Trustee to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver to any Note Document authorized
pursuant to this Article IX if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment, supplement or waiver to any Note Document
until the Board of Directors of the Issuer approves it. In executing any amendment, supplement or waiver to any Note Document, the Trustee shall receive and (subject to Sections 7.1 and 7.2) shall be fully protected in
conclusively relying upon, in addition to the documents required by Section 12.4, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amendment, supplement or waiver is authorized or permitted by
this Indenture and is valid, binding and enforceable against the Issuer or any Guarantor, as the case may be, in accordance with its terms. 

ARTICLE X 
 GUARANTEE 

SECTION 10.1. Guarantee. The obligations of the Issuer under the Notes and this Indenture shall be, jointly and severally,
unconditionally guaranteed on a senior unsecured basis (the “Note Guarantees”) by the Guarantors. Subject to the provisions of this Article X, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as
primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes 

  
 -122- 

 
and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest, if any, on the Notes
and all other obligations and liabilities of the Issuer under the Note Documents (including without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to the Issuer or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding and the obligations under Section 7.7) (all the foregoing being hereinafter collectively
called the “Guaranteed Obligations”). Each Guarantor agrees that the Guaranteed Obligations will rank equally in right of payment with other Indebtedness of such Guarantor, except to the extent such other Indebtedness is subordinate
to the Guaranteed Obligations, in which case the obligations of the Guarantors under the Note Guarantees will rank senior in right of payment to such other Indebtedness. 

Each Guarantor hereby agrees that its Note Guarantee set forth in this Section 10.1 shall remain in full force and effect
notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. 
 If an Officer whose signature is on the
applicable 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. 

Each Guarantor further agrees (to the extent permitted by law) that the Guaranteed Obligations may be extended or renewed, in whole or in
part, without notice or further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Guaranteed Obligation. 

Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives
notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. 
 Each
Guarantor further agrees that its Note Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the
Guaranteed Obligations. 
 Except as set forth in Section 10.2, the obligations of each Guarantor hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense
of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the Guaranteed Obligations of
each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of the Trustee or any Holder to assert any claim or demand or to enforce any right or remedy against the Issuer or any other person under this
Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other
agreement; (d) the release of any security held by any Holder for the Guaranteed Obligations; (e) the failure of the Trustee or any Holder to exercise 

  
 -123- 

 
any right or remedy against any other Guarantor; (f) any change in the ownership of the Issuer; (g) any default, failure or delay, willful or otherwise, in the performance of the
Guaranteed Obligations; or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor
as a matter of law or equity. 
 Each Guarantor agrees that its Note Guarantee herein shall remain in full force and effect until payment in
full of all the Guaranteed Obligations or such Guarantor is released from its Note Guarantee in compliance with Section 10.2, Article VIII or Article XI. Each Guarantor further agrees that its Note Guarantee
herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by
any Holder upon the bankruptcy or reorganization of the Issuer or otherwise. 
 In furtherance of the foregoing and not in limitation of any
other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders (or the Trustee on behalf of the Holders) an amount equal to the sum of
(i) the unpaid amount of such Guaranteed Obligations then due and owing and (ii) accrued and unpaid interest, if any, on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest
accruing after the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Issuer or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in
such proceeding). 
 Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand,
(x) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Guaranteed Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith
become due and payable by the Guarantor for the purposes of this Note Guarantee. 
 Each Guarantor also agrees to pay any and all fees,
costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.1. 

SECTION 10.2. Limitation on Liability; Termination, Release and Discharge. 

(a) Any term or provision of this Indenture to the contrary notwithstanding, the obligations of each Guarantor hereunder will be limited to the
maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such
other Guarantor under its Note Guarantee or pursuant to its contribution 

  
 -124- 

 
obligations under this Indenture, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, foreign or
state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally. 
 (b) The Note
Guarantee of a Subsidiary Guarantor shall automatically terminate upon: 
 (1) a sale or other disposition (including by way
of consolidation or merger) of the Capital Stock of such Subsidiary Guarantor after which such Subsidiary Guarantor is no longer a Subsidiary of Holdings but only to the extent such sale or disposition is otherwise permitted under this Indenture;

 (2) the designation in accordance with this Indenture of such Subsidiary Guarantor as an Unrestricted Subsidiary; 

(3) defeasance or discharge of the Notes pursuant to Article VIII or XI; or 

(4) in the case of a Note Guarantee made by a Subsidiary Guarantor as a result of its Guarantee of other Indebtedness of the
Issuer or a Guarantor pursuant to Section 3.7, such Guarantor being released from all of its obligations under its Guarantee of such other Indebtedness, except a release as a result of the repayment or discharge of such other
Indebtedness (it being understood that a release or discharge subject to a contingent reinstatement is still considered a release or discharge, and if any such other Indebtedness is reinstated, such Note Guarantee shall also be reinstated). 

(c) The Note Guarantee of Holdings or any other direct or indirect parent of the Issuer that provides a Guarantee will terminate upon
defeasance or discharge of the Notes, pursuant to Article VIII or Article XI. 
 (d) If the Note Guarantee of any
Guarantor is terminated, the Issuer shall deliver to the Trustee an Officer’s Certificate stating the identity of the Guarantor, the basis for termination in reasonable detail, and that such termination complies with this Indenture. 

SECTION 10.3. Right of Contribution. Each Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its
proportionate share of any payment made on the obligations under the Note Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Issuer or any other Guarantor who has not paid its proportionate share of
such payment. The provisions of this Section 10.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the
full amount guaranteed by such Guarantor hereunder. 
 SECTION 10.4. No Subrogation. Notwithstanding any payment or payments made by
each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Issuer or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or
any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or 

  
 -125- 

 
reimbursement from the Issuer or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Issuer on account of
the Guaranteed Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guaranteed Obligations shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such
Guarantor to the Trustee, if required), to be applied against the Guaranteed Obligations. 
 ARTICLE XI 

SATISFACTION AND DISCHARGE 

SECTION 11.1. Satisfaction and Discharge. This Indenture will be discharged and cease to be of further effect (except as to surviving
rights of transfer or exchange of the Notes the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s and Guarantors’ obligations in connection therewith, and as expressly provided for in this Indenture)
as to all outstanding Notes when: 
 (a) either: 

(1) all the Notes previously authenticated and delivered (other than lost, stolen or destroyed Notes and Notes for which
provision for payment was previously made and thereafter the funds have been released to the Holders) have been delivered to the Trustee for cancellation; or 

(2) all Notes not previously delivered to the Trustee for cancellation (i) have become due and payable, (ii) will
become due and payable at their Stated Maturity within one year or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at
the expense, of the Issuer; 
 (b) the Issuer has deposited or caused to be deposited with the Trustee, money in United States Dollars or
U.S. Government Obligations, or a combination thereof, as applicable, in an amount sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire indebtedness on the Notes not previously delivered to the Trustee
for cancellation, for principal, premium, if any, and interest to the date of deposit (in the case of Notes that have become due and payable), or to the Stated Maturity or redemption date, as the case may be; 

(c) the Issuer has paid or caused to be paid all other sums payable under this Indenture; 

(d) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of such notes issued
hereunder at maturity or the redemption date, as the case may be; and 

  
 -126- 

 (e) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel each stating that all conditions precedent under this Article XI relating to the satisfaction and discharge of this Indenture have been complied with; provided that any such counsel may rely on any Officer’s
Certificate as to matters of fact (including as to compliance with the foregoing clauses (a), (b) and (c)). 

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to
clause (b) of this Section 11.1, the provisions of Sections 11.2 and 8.6 will survive. After the conditions to discharge contained in this Article XI have been satisfied, and the Issuer has paid
or caused to be paid all other sums payable hereunder by the Issuer, and delivered to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that all conditions precedent to satisfaction and discharge have been satisfied, the
Trustee upon Issuer Order shall (i) acknowledge in writing the discharge of the obligations of the Issuer and the Guarantors under this Indenture (except for those surviving obligations specified in Section 11.2 and the rights,
powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s and Guarantors’ obligations in connection therewith) and (ii) transfer funds then on deposit with the Trustee in excess of those required for such
satisfaction and discharge in accordance with such Issuer Order. 
 SECTION 11.2. Application of Trust Money. Subject to the
provisions of Section 8.6, all money deposited with the Trustee pursuant to Section 11.1 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 U.S. Government Obligations in accordance with Section 11.1 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 11.1;
provided that if the Issuer has made any payment of principal of, premium 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 U.S. Government Obligations held by the Trustee or Paying Agent.

the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, any Guarantor or any Affiliate of any of them shall be disregarded and deemed not to be outstanding,
except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. In
connection with any such direction, waiver or consent, the Issuer shall furnish to the Trustee an Officer’s Certificate listing and identifying all Notes, if any, known by the Issuer to be owned by or for the account of any of the

final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Issuer or the Guarantors, as the case may be, and may be enforced in any court to the jurisdiction of which the Issuer or the

SECTION 12.20. Waiver of Immunities. To the extent that Issuer or any Guarantor or any of its properties, assets or revenues may have
or may hereafter become entitled to, or have attributed to them, any right of immunity, on the grounds of sovereignty, from any legal action, suit or proceeding, from set-off or counterclaim, from the jurisdiction of any court, from service of
process, from attachment upon or prior to judgment, or from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any
jurisdiction in which proceedings may at any time be commenced, with respect to their obligations, liabilities or any other matter under or arising out of or in connection with this Indenture, the Notes or the Note Guarantees, the Issuer and each
Guarantor hereby irrevocably and unconditionally, to the extent permitted by applicable law, waives and agrees not to plead or claim any such immunity and consents to such relief and enforcement. 

SECTION 12.21. Judgment Currency. The Issuer and each Guarantor shall jointly and severally indemnify the recipient against any loss
incurred by such recipient as a result of any judgment or order being given or made against the Issuer or any Guarantor for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “Judgment
Currency”) other than United States Dollars and as a result of any variation as between (i) the rate of exchange at which the United States Dollar amount is converted into the Judgment Currency for the purpose of such judgment or
order, and (ii) the rate of exchange in The City of New York at which such party on the date of payment of such judgment or order is able to purchase United States Dollars with the amount of the Judgment Currency actually received by such party
if such party had utilized such amount of Judgment Currency to purchase United States dollars as promptly as practicable upon such party’s receipt thereof. The foregoing indemnity shall constitute a separate and independent obligation of the
Issuer and each Guarantor and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the
purchase of, or conversion into, the relevant currency.

 [FORM OF REVERSE SIDE OF NOTE] 

GREATBATCH LTD. 
 9.125% Senior
Notes due 2023 
 Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. 

 

	1.	Interest 

 The Issuer promises to pay interest on the principal amount of this Note at
9.125% per annum from October 27, 20153 until maturity. The Issuer will pay interest semi-annually in arrears every May 1 and November 1 of each year, or if any such day is not
a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from
October 27, 20154; provided, that the first Interest Payment Date shall be May 1, 2016.5 The Issuer shall pay interest on
overdue principal at the rate specified herein, and the Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at
the same rate to the extent lawful. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. Each interest period will end on (but not include) the relevant Interest Payment Date. 

 

	2.	Method of Payment 

 By no later than 10:00 a.m. (New York City time) on the date on which
any principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall deposit with the Paying Agent a sum sufficient (in United States Dollars in immediately available funds) to pay such principal, premium, and interest
when due. Interest on any Note which is payable, and is timely paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on
the preceding April 15 or October 15, as applicable, at the office or agency of the Issuer maintained for such purpose pursuant to Section 2.3 of the Indenture. The principal of, premium, if any and interest on the Notes shall
be payable at the office or agency of Paying Agent or Registrar designated by the Issuer maintained for such purpose (which shall initially be the office of the Trustee maintained for such purpose), or at such other office or agency of the Issuer as
may be maintained for such purpose pursuant to Section 2.3 of the Indenture; provided, however, that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to addresses of the
Persons entitled thereto as such addresses shall appear on the Notes Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Notes
represented by a Global Note (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository. Payments in respect
of Notes represented by Definitive 
  

	3 	In the case of Notes issued on the Issue Date. 

	4 	In the case of Notes issued on the Issue Date. 

	5 	 In the case of Notes issued on the Issue Date. 

  
 A-4 

 
Notes (including principal, premium, if any, and interest) held by a Holder of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes will be made by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later
than fifteen (15) days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). If an Interest Payment Date is a Legal Holiday, payment shall be made on the next succeeding day
that is not a Legal Holiday, and no interest shall accrue for the intervening period. If a regular record date is a Legal Holiday, the record date shall not be affected. All payments will be made in United States Dollars. 

 

	3.	Paying Agent and Registrar 

 The Issuer initially appoints Wilmington Trust, National
Association (the “Trustee”) as Registrar and Paying Agent for the Notes. The Issuer may change any Registrar or Paying Agent without prior notice to the Holders. The Issuer or any Guarantor may act as Paying Agent, Registrar or
transfer agent. 
  

	4.	Indenture 

 The Issuer issued the Notes under an Indenture dated as of October 27,
2015 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Issuer, the Guarantors from time to time party thereto and the Trustee. The terms of the Notes include
those stated in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and Holders are referred to the Indenture for a statement of those terms. 
  

	5.	Guarantees 

 To guarantee the due and punctual payment of the principal and interest, if
any (including post-filing or post-petition interest) on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise,
according to the terms of the Notes and the Indenture, the Guarantors will unconditionally guarantee (and future guarantors, jointly and severally with the Guarantors, jointly and severally, will fully and unconditionally Guarantee) such obligations
on a senior unsecured basis pursuant to the terms of the Indenture. 
  

	6.	Optional Redemption 

 (a) At any time and from time to time prior to November 1,
2018, the Issuer may redeem the Notes in whole or in part, at its option, upon notice in accordance with Section 5.3 of the Indenture, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the
Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the redemption date. 
 (b) At any time and from
time to time on or after November 1, 2018, the Issuer may redeem the Notes in whole or in part, upon notice in accordance with Section 5.3 of the Indenture, at a redemption price equal to the percentage of principal amount set forth
below plus

	  	102.281%
	 2021 and thereafter

 (c) At any time and from time to time prior to November 1, 2018, the Issuer may redeem Notes, upon notice
in accordance with Section 5.3 of the Indenture, with the net cash proceeds from any Equity Offering (other than Excluded Contributions) that are contributed by Holdings to the common equity capital of the Issuer at a redemption price
(expressed as a percentage of principal amount) equal to 109.125% plus accrued and unpaid interest, if any, to but not including, the redemption date, in an aggregate principal amount for all such redemptions not to exceed 40% of the original
aggregate principal amount of the Notes (including Additional Notes); provided that: 
 (1) in each case the
redemption takes place not later than 90 days after the closing of the related Equity Offering; and 
 (2) not less than
60% of the original aggregate principal amount of the Notes issued under the Indenture remains outstanding immediately thereafter (excluding Notes held by the Issuer or any of its Restricted Subsidiaries). 

(d) Any redemption and notice of any such redemption may, at the Issuer’s discretion, be subject to the satisfaction of one or more
conditions precedent (including, in the case of a redemption related to an Equity Offering, the consummation of such Equity Offering). 

(e) If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and
unpaid interest will be paid to the Person in whose name the Note is registered at the close of business (New York City time) on such record date, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the
Issuer. 
 (f) Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions
thereof called for redemption on the applicable redemption date. 
 (g) Any redemption pursuant to this paragraph 6 shall be
made pursuant to the provisions of Sections 5.1 through 5.6 of the Indenture. 
 The Issuer is not required to make
mandatory redemptions or sinking fund payments with respect to the Notes; provided, however, that under certain circumstances, the Issuer may be required to offer to purchase Notes under Section 3.5 and
Section 3.9 of the Indenture. The Issuer may at any time and from time to time purchase Notes in the open market or otherwise.

	8.	Repurchase Provisions 

 If a Change of Control occurs, subject to
Section 3.5(c) of the Indenture, each Holder will have the right to require the Issuer to repurchase from each Holder all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes at a
purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to but not including the date of purchase, subject to the right of Holders of record on the relevant record date to receive
interest due on the relevant interest payment date as provided in, and subject to the terms of, the Indenture. 
 Upon certain Asset

the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to but not including the date of purchase, in accordance with the procedures set forth in, and subject to the
terms of, the Indenture.

form in minimum denominations of principal amount of $2,000 and any integral multiple of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any tax and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Note (A) for a period
beginning (1) fifteen (15) days before the mailing of a notice of an offer to repurchase or redeem Notes and ending at the close of business on the day of such mailing or sending or (2) fifteen (15) days before an Interest
Payment Date and ending on such Interest Payment Date or (B) called for redemption, except the unredeemed portion of any Note being redeemed in part. 
  

	10.	Persons Deemed Owners 

 The registered Holder of this Note may be treated as the owner of
it for all purposes. 
  

	11.	Discharge and Defeasance 

 Subject to certain exceptions and conditions and the other
terms set forth in the Indenture, the Issuer at any time may terminate some or all of its obligations under the Notes and the Indenture if the Issuer deposits with the Trustee money in United States Dollars or U.S. Government Obligations for the
payment of principal, premium, if any, and interest, if any on the Notes to redemption or maturity, as the case may be. 
  

	12.	Amendment, Supplement, Waiver 

 Subject to certain exceptions and other items contained
in the Indenture, Note Documents may be amended, supplemented or waived, with the consent of the Holders of a majority in 

  
 A-7 

 
aggregate principal amount of the outstanding Notes (including consents obtained in connection with a purchase, or tender offer or exchange offer for, such Notes). Without notice to or the
consent of any Holder, the Issuer, the Guarantors and the Trustee may amend or supplement the Note Documents as provided in the Indenture. 
  

	13.	Defaults and Remedies 

 If an Event of Default (other than an Event of Default described
in Section 6.1(a)(6) or (7) of the Indenture) occurs and is continuing, the Trustee by notice to the Issuer, or the Holders of at least 30% in principal amount of the outstanding Notes by notice to the Issuer and the Trustee,
may declare the principal of, and accrued and unpaid interest, on all the Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal and accrued and unpaid, interest will be due and payable immediately. If an
Event of Default described in Section 6.1(a)(6) or (7) occurs, the principal of, and accrued and unpaid interest on, all the Notes will become and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind an acceleration with respect to the Notes and its consequences. 

 

	14.	Trustee Dealings with the Issuer 

 Subject to certain limitations set forth in the
Indenture, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, Guarantors or their Affiliates with the same rights it would have if it were not Trustee. In addition,
the Trustee shall be permitted to engage in transactions with the Issuer; provided, however, that if the Trustee acquires any conflicting interest under the Trust Indenture Act, the Trustee must (i) eliminate such conflict within
90 days of acquiring such conflicting interest or (ii) resign. 
  

	15.	No Recourse Against Others 

 No director, officer, employee, incorporator or shareholder
of the Issuer or any of its Subsidiaries or Affiliates, solely in their capacities as such (other than the Issuer and the Guarantors), shall have any liability for any obligations of the Issuer under the Note Documents or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

 

	16.	Authentication

Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Note.

This certificate is delivered to request a transfer of $[        ] principal amount of the 9.125%

 Upon transfer, the Notes would

 The undersigned represents and warrants to you that: 

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under
the Securities Act of 1933, as amended (the “Securities Act”)) purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Notes, and we are
acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits
and risk of our investment in the Notes and we invest in or purchase securities similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment.

 2. We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of
original issue and the last date on which the Issuer or any affiliate of the Issuer was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuer or any Subsidiary
thereof, (b) pursuant to an effective registration statement under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a “qualified
institutional buyer” under Rule 144A of the Securities Act (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on
Rule 144A, (d) pursuant to offers and sales to non-U.S. persons that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the
meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum
principal amount of Notes of $250,000 for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act or (f) pursuant to any other available exemption from the
registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control
and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to
clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuer and the Trustee, which shall provide, among other things,
that the transferee is an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and that it is acquiring such Notes for investment purposes and
not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Issuer and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Termination Date of the Notes pursuant to
clauses (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Issuer.

 9.125% Senior Notes due 2023 (the
“Notes”) 
 Ladies and Gentlemen: 

In connection with our proposed sale of $[         ] aggregate principal amount of the Notes, we
confirm that such sale has been effected pursuant to and in accordance with Regulation S under the United States Securities Act of 1933, as amended (the “Securities Act”), and, accordingly, we represent that: 

(a) the offer of the Notes was not made to a U.S. person (within the meaning of Regulation S); 

(b) either (i) at the time the buy order was originated, the transferee was outside the United States or we and any person
acting on our behalf reasonably believed that the transferee was outside the United States or (ii) the transaction was executed in, on or through the facilities of a designated off-shore securities market and neither we nor any person acting on
our behalf knows that the transaction has been pre-arranged with a buyer in the United States; 
 (c) no directed selling
efforts have been made in the United States in contravention of the requirements of Rule 903(a)(2) or Rule 904(a)(2) of Regulation S, as applicable; and 

(d) the transaction is not part of a plan or scheme to evade the registration requirements of the Securities Act. 

  
 E-1 

 In addition, if the sale is made during a restricted period and the provisions of
Rule 903(b)(2), Rule 903(b)(3) or Rule 904(b)(1) of Regulation S are applicable thereto, we confirm that such sale has been made in accordance with the applicable provisions of Rule 903(b)(2), Rule 903(b)(3) or
Rule 904(b)(1), as the case may be. 
 We also hereby certify that we [are][are not] an Affiliate of the Issuer and, to our knowledge,
the transferee of the Notes [is][is not] an Affiliate of the Issuer. 
 The Trustee, Registrar and the Issuer are entitled to
conclusively rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to the matters covered hereby. Terms used

 WHEREAS, on
August 27, 2015, the Company, Lake Region Medical Holdings, Inc., a Delaware corporation (“Lake Region”), and Provenance Merger Sub Inc., a Delaware corporation and wholly-owned indirect subsidiary of the Company
(“Merger Subsidiary”), entered into an Agreement and Plan of Merger (as it may be amended from time to time, the “Merger Agreement”) pursuant to which, among other things, the Merger Subsidiary will be merged with

 WHEREAS, pursuant to
and subject to the terms and conditions of the Merger Agreement, in connection with the Merger, the Investors (as defined below) are expected to receive shares of Company Common Stock (the shares of Company Common Stock to be received by the

WHEREAS, each of the parties hereto wishes to set forth in this Agreement certain terms and conditions regarding the Investors’ ownership

 NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this
Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties agree as follows: 

ARTICLE I 
 TRANSFERS;
STANDSTILL PROVISIONS 
 1.1. Transfer Restrictions. 

(a) Other than solely in the case of a Permitted Transfer, no Investor shall Transfer any Shares prior to the date that is six (6) months
after the Closing (such period, the “Restricted Period”). 

  
 2 

 (b) “Permitted Transfers” mean, in each case, so long as such Transfer is in accordance
with Applicable Law and, solely in the case of sub-clause (i) below, any such Transfer would not result in the Bain Investors or the KKR Investors, as applicable, exceeding the Bain Ownership Limit or the KKR Ownership Limit, respectively: 

(i) a Transfer to a Permitted Transferee of the applicable Investor, so long as such Permitted Transferee, in connection with
such Transfer, executes a joinder to this Agreement in the form attached as Exhibit A hereto, in which such Permitted Transferee agrees to be a “Bain Investor,” in the case of a Transfer by a Bain Investor or a “KKR
Investor,” in the case of a Transfer by a KKR Investor; or 
 (ii) a Transfer solely to tender into a tender or exchange
offer commenced by a third party (for the avoidance of doubt, not in violation of this Agreement) or by the Company; provided, that with respect to an unsolicited tender or exchange offer commenced by a third party, such Transfer shall be permitted
only if (A) such tender or exchange offer includes an irrevocable minimum tender condition of no less than a majority of the then-outstanding shares of Company Common Stock and (B) as of the expiration of such offer (x) no stockholder
rights plan or analogous “poison pill” of the Company is in effect or (y) the Board has affirmatively publicly recommended to the Company’s stockholders that such stockholders tender into such offer and has not publicly withdrawn
or changed such recommendation. 
 (c) Notwithstanding anything to the contrary contained herein, including Article IV hereof and the
expiration or inapplicability of the Restricted Period, no Investor shall Transfer any Voting Securities other than in accordance with all Applicable Laws and, in the case of Transfers made pursuant to Article IV hereof, the other terms and
conditions of this Agreement. 
 (d) Any Transfer or attempted Transfer of Voting Securities in violation of this Section 1.1 shall, to
the fullest extent permitted by Applicable Law, be null and void ab initio, and the Company shall not, and shall instruct its transfer agent and other third parties not to, record or recognize any such purported transaction on the share register of
the Company. 
 (e) With respect to any Bain Investor or KKR Investor, any certificates for Shares shall bear a legend or legends (and
appropriate comparable notations or other arrangements will be made with respect to any uncertificated Shares) referencing restrictions on Transfer of such Shares under the Securities Act and under this Agreement, which legend shall state in
substance: 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
“ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS REGISTERED UNDER THE ACT OR UNLESS AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT IS AVAILABLE. 

  
 3 

 THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A
STOCKHOLDERS AGREEMENT, DATED AS OF OCTOBER 27, 2015, AMONG GREATBATCH, INC. AND THE OTHER PARTIES THERETO, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF GREATBATCH, INC.” 

(f) Notwithstanding the foregoing subsection (e), the holder of any certificate(s) for Shares shall be entitled to receive from the Company
new certificates for a like number of Shares not bearing such legend (or the elimination or termination of such notations or arrangements) upon the request of such holder (i) at such time as such restrictions are no longer applicable, and
(ii) with respect to the restriction on Transfer of such Shares under the Securities Act or any other applicable Foreign or State Act, unless such Shares are sold pursuant to a registration statement, subject to delivery of an opinion of
counsel to such holder, which opinion is reasonably satisfactory in form and substance to the Company and its counsel, that the restriction referenced in such legend (or such notations or arrangements) is no longer required in order to ensure
compliance with the Securities Act or any such other applicable Foreign or State Act.

engage in, any “solicitation” of “proxies” (as such terms are used in the proxy rules of the Commission) to vote, or advise or 

  
 4

 ARTICLE IV 

REGISTRATION 
 4.1.
Demand Registrations. 
 (a) From and after the expiration of the Restricted Period, subject to the terms and conditions hereof
(x) solely during any period that the Company is then-ineligible under Applicable Law to register Registrable Securities on Form S-3 pursuant to Section 4.3 or, if the Company is so eligible but has failed to comply with its obligations
under Section 4.3 or (y) following the expiration of the Company’s obligation to keep the Shelf Registration Statement continuously effective pursuant to Section 4.3(c), but only if there is no Shelf Registration Statement then
in effect, any Demand Stockholders (the “Requesting Stockholders”) shall be entitled to make an unlimited number of written requests of the Company (each, a “Demand”) for registration under the Securities Act of an
amount of Registrable Securities then held by such Requesting Stockholders that equals or is greater than the Registrable Amount (a “Demand Registration”). Thereupon the Company will, subject to the terms of this Agreement, use its
reasonable best efforts to effect the registration as promptly as reasonably practicable under the Securities Act of: 
 (i)
the Registrable Securities which the Company has been so requested to register by the Requesting Stockholders for disposition in accordance with the intended method of disposition stated in such Demand; 

(ii) all other Registrable Securities which the Company has been requested to register pursuant to Section 4.1(b), but
subject to Section 4.1(g); and 
 (iii) all shares of Company Common Stock which the Company may elect to register in
connection with any offering of Registrable Securities pursuant to this Section 4.1, but subject to Section 4.1(g); 

  
 8 

 all to the extent necessary to permit the disposition (in accordance with the intended methods
thereof) of the Registrable Securities and the additional shares of Company Common Stock, if any, to be so registered. 
 (b) A Demand shall
specify: (i) the aggregate number of Registrable Securities requested to be registered in such Demand Registration, (ii) the intended method of disposition in connection with such Demand Registration, to the extent then known and
(iii) the identity of the Requesting Stockholder(s). Within three (3) Business Days after receipt of a Demand, the Company shall give written notice of such Demand to all holders of Registrable Securities. The Company shall include in the
Demand Registration covered by such Demand all Registrable Securities with respect to which the Company has received a written request (which written requests shall specify the number of Registrable Securities requested to be disposed of by such
holder of Registrable Securities) for inclusion therein from any holder of Registrable Securities (any such holders requesting to include Registrable Securities in such Demand, together with the Requesting Stockholder, the “Demanding Selling
Holders”) within five (5) days after the Company’s notice required by this paragraph has been given, subject to Section 4.1(g). Each such written request shall comply with the requirements of a Demand as set forth in this
Section 4.1(b). 
 (c) A Demand Registration shall not be deemed to have been effected and shall not count as a Demand Registration
(i) unless a registration statement with respect thereto has become effective and has remained effective for a period of at least one hundred eighty (180) days or such shorter period in which all Registrable Securities included in such
Demand Registration have actually been sold thereunder (provided, that such period shall be extended for a period of time equal to the period the holder of Registrable Securities refrains from selling any securities included in such registration
statement at the request of the Company or the lead managing underwriter(s) pursuant to the provisions of this Agreement) or (ii) if, after it has become effective, such Demand Registration becomes subject, prior to one hundred eighty
(180) days after effectiveness, to any stop order, injunction or other order or requirement of the Commission or other Governmental Authority, other than by reason of any act or omission by the applicable Selling Stockholders. 

(d) Demand Registrations shall be on such appropriate registration form of the Commission as shall be selected by the Company and reasonably
acceptable to the Requesting Stockholders. 
 (e) The Company shall not be obligated to (i) subject to Section 4.1(c), maintain
the effectiveness of a registration statement under the Securities Act filed pursuant to a Demand Registration, for a period longer than one hundred eighty (180) days or (ii) effect or act upon any request for a Demand Registration
(A) if the Company is diligently pursuing a primary Underwritten Offering for which all Demand Stockholders will be offered “piggyback” rights pursuant to Section 4.2, (B) within six (6) months of the completion of a
“firm commitment” Underwritten Offering in which all holders of Registrable Securities were offered “piggyback” rights pursuant to Section 4.2 (subject to Section 4.2(b)) and at least 75% of the number of Registrable
Securities requested by such holders of Registrable Securities to be included in such Demand Registration were included and sold, (C) within six (6) months of the completion of any other Demand Registration (including, for the avoidance of
doubt, any Underwritten Offering 

  
 9 

 
pursuant to any Shelf Registration Statement) or (D) if, in the Company’s reasonable judgment, it is not feasible for the Company to proceed with the Demand Registration because of the
unavailability of audited or other required financial statements; provided, that the Company shall use its reasonable best efforts to obtain such financial statements as promptly as reasonably practicable. 

(f) The Company shall be entitled (upon written notice to the Demand Stockholders and Bain) to postpone or delay the filing or the
effectiveness of, or suspend the continued use of, a registration statement for any Demand Registration in the event of a Blackout Period until the expiration of the applicable Blackout Period. In the event of a Blackout Period under clause
(ii) of the definition thereof, the Company shall deliver to the Demand Stockholders and Bain a certificate signed by either the chief executive officer or the chief financial officer of the Company certifying that, in the good faith judgment
of the Company, the conditions described in clause (ii) of the definition of Blackout Period are met. Such certificate shall contain an approximation of the anticipated delay or, if the Company is unable to provide an approximation of the
anticipated delay, a certification that the Company is unable to provide an approximation of the anticipated delay. During the Blackout Period, the holders of Registrable Securities agree to suspend use of the applicable prospectus and any Free
Writing Prospectus in connection with any sale or purchase, or offer to sell or purchase, Registrable Securities, upon distribution of the written notice referred to above. After the termination of the Blackout Period and without any further request
from a Demand Stockholder, the Company shall, to the extent necessary, as promptly as reasonably practicable, supplement, make amendments to or prepare a post-effective amendment or supplement to the registration statement for the Demand
Registration or the prospectus, or any document incorporated therein by reference, or any Free Writing Prospectus or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the
prospectus does not contain any untrue statement of material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(g) If, in connection with a Demand Registration that involves an Underwritten Offering, the lead managing underwriter(s) advise(s) the
Company that, in its (their) opinion, the inclusion of all of the securities sought to be registered in connection with such Demand Registration would adversely affect the success thereof, then the Company shall include in such registration
statement only such securities as the Company is advised by such lead managing underwriter(s) can be sold without such adverse effect as follows and in the following order of priority: (i) first, up to the number of Registrable Securities
requested to be included in such Demand Registration by the Demanding Selling Holders, with any required reductions to such amounts requested to be included made in the following manner: (x) first, to the extent that the Demanding Selling
Holders are each selling a different percentage of the total Registrable Securities owned by each such Demanding Selling Holder, by reducing the number of Registrable Securities requested to be included by a Demanding Selling Holder that is selling
a greater percentage of its total Registrable Securities than is requested to be included by the other Demanding Selling Holders until each such Demanding Selling Holder is selling in such Demand the same percentage of the total number of
Registrable Securities owned by it after giving effect to such reductions (for example, if the first Demanding Selling Holder is requesting to sell 50% of the total Registrable Securities owned by it and the second Demanding Selling

  
 10 

 
Holder is requesting to sell 10% of the total Registrable Securities owned by it, then the number of Registrable Securities requested to be included by the first Demanding Selling Holder will be
reduced as required until such first Demanding Selling Holder is selling only 10% of its total Registrable Securities and no reductions will be made to the number of Registrable Securities requested to be included by the second Demanding Selling
Holder under this clause (x)) and (y) if additional reductions are required to be made, pro rata among such Demanding Selling Holders on the basis of the number of such Registrable Securities requested to be included by such Demanding Selling
Holders after giving effect to the reductions in clause (x); (ii) second, securities the Company proposes to sell; and (iii) third, all other securities of the Company duly requested to be included in such registration statement, pro rata
on the basis of the amount of such other securities requested to be included or such other allocation method determined by the Company. 

(h) Any time that a Demand Registration involves an Underwritten Offering, the Requesting Stockholder(s) shall select the investment banker(s)
and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve as lead or co-lead) and underwriters with respect to the offering of such Registrable Securities; provided, that such investment banker(s)
and manager(s) shall be reasonably acceptable to the Company (such acceptance not to be unreasonably withheld, conditioned or delayed). 

4.2. Piggyback Registrations. 

(a) From and after the expiration of the Restricted Period, subject to the terms and conditions hereof, whenever the Company proposes to
register any Company Common Stock under the Securities Act (other than a registration by the Company (i) on Form S-4 or any successor form thereto, (ii) on Form S-8 or any successor form thereto, (iii) on a Shelf Registration
Statement pursuant to Section 4.3 or (iv) pursuant to Section 4.1) (a “Piggyback Registration”), whether for its own account or for the account of others, the Company shall give reasonably prompt written notice
thereof (but not less than ten (10) Business Days prior to the filing by the Company with the Commission of any registration statement with respect thereto) to all holders of Registrable Securities. Such notice (a “Piggyback
Notice”) shall specify the number of shares of Company Common Stock that the Company proposes to register, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the proposed
managing underwriter(s) (if any) and a good faith estimate by the Company of the proposed minimum offering price of such shares of Company Common Stock, in each case to the extent then known. Subject to Section 4.2(b), the Company shall include
in each such Piggyback Registration all Registrable Securities held by holders of Registrable Securities (a “Piggyback Seller”) with respect to which the Company has received written requests (which written requests shall specify
the number of Registrable Securities requested to be disposed of by such Piggyback Seller) for inclusion therein from any holder of Registrable Securities within ten (10) days after such Piggyback Notice is given by the Company. 

(b) If, in connection with a Piggyback Registration that involves an Underwritten Offering, the lead managing underwriter(s) advises the
Company that, in its opinion, the inclusion of all the shares of Company Common Stock sought to be included in such Piggyback Registration by (i) the Company, (ii) other Persons who have sought to have shares of Company Common Stock
registered in such Piggyback Registration pursuant to rights to demand 

  
 11 

 
(other than pursuant to so-called “piggyback” or other incidental or participation registration rights) such registration (such Persons being “Other Demanding
Sellers”), (iii) the Piggyback Sellers and (iv) any other proposed sellers of shares of Company Common Stock (such Persons being “Other Proposed Sellers”), as the case may be, would adversely affect the success
thereof, then the Company shall include in the registration statement applicable to such Piggyback Registration only such shares of Company Common Stock as the Company is advised by such lead managing underwriter(s) can be sold without such an
effect, as follows, and in the following order of priority: 
 (i) if the Piggyback Registration relates to an offering for
the Company’s own account, then (A) first, such number of shares of Company Common Stock to be sold by the Company as the Company, acting in good faith, shall have determined, (B) second, Registrable Securities of Piggyback Sellers,
with any required reductions to such amounts requested to be included made in the following manner: (x) first, to the extent that the Piggyback Sellers are each selling a different percentage of the total Registrable Securities owned by each
such Piggyback Seller, by reducing the number of Registrable Securities requested to be included by a Piggyback Seller that is selling a greater percentage of its total Registrable Securities than is requested to be included by the other Piggyback
Sellers until each such Piggyback Seller is selling in such Piggyback Registration the same percentage of the total number of Registrable Securities owned by it after giving effect to such reductions; and (y) if additional reductions are
required to be made, pro rata on the basis of the number of Registrable Securities proposed to be sold by such Piggyback Sellers, (C) third, shares of Company Common Stock sought to be registered by Other Demanding Sellers, pro rata on the
basis of the number of shares of Company Common Stock proposed to be sold by such Other Demanding Sellers and (D) fourth, other shares of Company Common Stock proposed to be sold by any Other Proposed Sellers, pro rata on the basis of the
number of shares of Company Common Stock proposed to be sold by such Other Proposed Sellers; or 
 (ii) if the Piggyback
Registration relates to an offering other than for the Company’s own account, then (A) first, such number of shares of Company Common Stock sought to be registered by each Other Demanding Seller pro rata in proportion to the number of
securities sought to be registered by all such Other Demanding Sellers, (B) second, Registrable Securities of Piggyback Sellers, with any required reductions to such amounts requested to be included made in the following manner: (x) first,
to the extent that the Piggyback Sellers are each selling a different percentage of the total Registrable Securities owned by each such Piggyback Seller, by reducing the number of Registrable Securities requested to be included by a Piggyback Seller
that is selling a greater percentage of its total Registrable Securities than is requested to be included by the other Piggyback Sellers until each such Piggyback Seller is selling in such Piggyback Registration the same percentage of the total
number of Registrable Securities owned by it after giving effect to such reductions and (y) if additional reductions are required to be made, pro rata on the basis of the number of shares of Company Common Stock proposed to be sold by such
Piggyback Sellers, (C) third, shares of Company Common Stock to be sold by the Company and (D) fourth, other shares of Company Common Stock proposed to be sold by any Other Proposed Sellers, pro rata on the basis of the number of shares of
Company Common Stock proposed to be sold by such Other Proposed Sellers. 

  
 12 

 (c) For clarity, in connection with any Underwritten Offering under this Section 4.2 for the
Company’s account, the Company shall not be required to include the Registrable Securities of a Piggyback Seller in the Underwritten Offering unless (i) such Piggyback Seller accepts the terms of the underwriting as agreed upon between the
Company and the lead managing underwriter(s), which shall be selected by the Company in its sole discretion, and (ii) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements,
lock-up letters and any other documents reasonably required under the terms of such arrangements within the timeframes set forth in Section 4.8(a) hereof. 

(d) If, at any time after giving written notice of its intention to register any shares of Company Common Stock as set forth in this
Section 4.2 and prior to the time the registration statement filed in connection with such Piggyback Registration is declared effective, the Company shall determine for any reason not to register such shares of Company Common Stock, the Company
may, at its election, give written notice of such determination to any Piggyback Seller within five (5) Business Days thereof and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such
particular withdrawn or abandoned Piggyback Registration; provided, that Demand Stockholders may continue the registration as a Demand Registration pursuant to the terms of Section 4.1. 

4.3. Shelf Registration Statement. 

(a) From and after the expiration of the Restricted Period, subject to the terms and conditions hereof, and further subject to the availability
of a registration statement on Form S-3 or any successor form thereto (“Form S-3”) to the Company, any of the Demand Stockholders may by written notice delivered to the Company (the “Shelf Notice”) require the
Company to file as soon as reasonably practicable, and to use reasonable best efforts to cause to be declared effective by the Commission as soon as reasonably practicable after such filing date, a Form S-3 providing for an offering to be made on a
continuous basis pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”) relating to the offer and sale, from time to time, of an amount of Registrable Securities then held by such Demand Stockholders that
equals or is greater than the Registrable Amount. Notwithstanding the foregoing, to the extent that upon the expiration of the Restricted Period the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act), a Shelf
Notice shall not be required and the Company shall file, as soon as reasonably practicable following the expiration of the Restricted Period, the Shelf Registration Statement in the form of an automatic shelf registration statement (as defined in
Rule 405 under the Securities Act) or any successor form thereto registering all Registrable Securities then held by any holder of Registrable Securities. 

(b) Within five (5) days after receipt of a Shelf Notice pursuant to Section 4.3(a), the Company will deliver written notice thereof
to all holders of Registrable Securities. Each other holder of Registrable Securities may elect to participate with respect to its Registrable Securities in the Shelf Registration Statement in accordance with the plan and method of distribution set
forth, or to be set forth, in such Shelf Registration Statement by delivering to the Company a written request to so participate within five (5) days after the Shelf Notice is given by the Company. 

  
 13 

 (c) Subject to Section 4.3(d), the Company will use its reasonable best efforts to keep the
Shelf Registration Statement, or any renewal Shelf Registration Statement upon the expiration of the prior Shelf Registration Statement, continuously effective until the earlier of (i) three (3) years after the initial Shelf Registration
Statement has been declared effective; (ii) the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus
included in the Shelf Registration Statement, or otherwise cease to be Registrable Securities; and (iii) the date on which this Agreement terminates pursuant to Section 6.1. 

(d) Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing
written notice to any holder of Registrable Securities who elected to participate in the Shelf Registration Statement, to require such holder of Registrable Securities to suspend the use of the prospectus for sales of Registrable Securities under
the Shelf Registration Statement during any Blackout Period. In the event of a Blackout Period under clause (ii) of the definition thereof, the Company shall deliver to the Demand Stockholders and Bain, a certificate signed by either the chief
executive officer or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in clause (ii) of the definition of Blackout Period are met. Such certificate shall contain an
approximation of the anticipated delay or, if the Company is unable to provide an approximation of the anticipated delay, a certification that the Company is unable to provide an approximation of the anticipated delay. During such Blackout Period,
holders of Registrable Securities who elected to participate in the Shelf Registration Statement agree to suspend use of the applicable prospectus or any Free Writing Prospectus in connection with any sale or purchase, or offer to sell or purchase,
Registrable Securities, upon distribution of the written notice referred to above. After the termination of the Blackout Period and without any further request from a holder of Registrable Securities, the Company shall, to the extent necessary, as
promptly as reasonably practicable, supplement, make amendments to or prepare a post-effective amendment or supplement to the Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or any Free Writing
Prospectus or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 (e) At any time
that a Shelf Registration Statement is effective, if any Demand Stockholder delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to sell all or part of its Registrable Securities included by it on the
Shelf Registration Statement in an Underwritten Offering (a “Shelf Offering”), then, the Company shall promptly amend or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities
to be distributed pursuant to the Shelf Offering (taking into account 

  
 14 

 
the inclusion of Registrable Securities by any other holders pursuant to this Section 4.3). In connection with any Shelf Offering that is an Underwritten Offering: 

(i) the Company shall within three (3) Business Days send the Take-Down Notice to any holder of Registrable Securities
included on the Shelf Registration Statement and the Company and such proposing Demand Stockholder(s) shall permit each such holder to include its Registrable Securities included on the Shelf Registration Statement in such Underwritten Offering if
such holder notifies the proposing Demand Stockholder(s) and the Company within three (3) days after distribution of the Take-Down Notice by the Company; 

(ii) the Company shall not be required to include the Registrable Securities of a holder in such Underwritten Offering unless
(A) such holder accepts the terms of the underwriting as agreed upon between the Demand Stockholder and the lead managing underwriter(s), and (B) completes and executes all questionnaires, powers of attorney, custody agreements,
indemnities, underwriting agreements, lock-up letters and any other documents reasonably required under the terms of such arrangements within the timeframes reasonably required by the Company and the lead managing underwriter(s); and 

(iii) if the lead managing underwriter(s) advises the Company and the proposing Demand Stockholder(s) that, in its opinion, the
inclusion of all of the securities sought to be sold in connection with such Underwritten Offering would adversely affect the success thereof, then there shall be included in such Underwritten Offering only such securities as the proposing Demand
Stockholder(s) is advised by such lead managing underwriter(s) can be sold without such adverse effect, and such number of Registrable Securities shall be allocated in the same manner as described in Section 4.1(g). Except as otherwise
expressly specified in this Section 4.3, any Shelf Offering that is an Underwritten Offering where the plan of distribution set forth in the applicable Take-Down Notice includes a customary “road show” (including an electronic road
show) or other substantial marketing effort by the Company and the underwriters (a “Marketed Underwritten Shelf Offering”) shall be subject to the same requirements, limitations and other provisions of this Article IV as would be
applicable to a Demand Registration (i.e., as if such Marketed Underwritten Shelf Offering were a Demand Registration), including Section 4.1(e)(ii) (provided that references therein to six (6) months shall be deemed to be references to
four (4) months) and Section 4.1(g). 
 4.4. Withdrawal Rights. Any holder of Registrable Securities having notified or
directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities
designated by it for registration by giving written notice to such effect to the Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not include such Registrable Securities in
the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement). No such withdrawal shall affect the obligations
of the Company with respect to the Registrable Securities not so withdrawn; provided, however, that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration
below the Registrable Amount, then the Company shall as promptly as practicable give each Demand Stockholder seeking to register Registrable 

  
 15 

 
Securities notice to such effect and, within ten (10) days following the mailing of such notice, such Demand Stockholders still seeking registration shall, by written notice to the Company,
elect to register additional Registrable Securities to satisfy the Registrable Amount or elect that such registration statement not be filed or, if theretofore filed, be withdrawn. During such ten (10) day period, the Company shall not file
such registration statement if not theretofore filed or, if such registration statement has been theretofore filed, the Company shall not seek, and shall use reasonable best efforts to prevent, the effectiveness thereof. 

4.5. Holdback Agreements. (a) In connection with any Underwritten Offering, each holder of Registrable Securities, agrees to enter
into customary agreements, subject to customary carve-outs, restricting the public sale or distribution of equity securities of the Company (including sales pursuant to Rule 144 under the Securities Act) to the extent requested by the lead managing
underwriter(s) with respect to an applicable Underwritten Offering during the period commencing on the tenth (10th) day prior to the date of the “pricing” of such Underwritten Offering and continuing for not more than sixty
(60) days after the date of the “final” prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration Statement), pursuant to which such Underwritten Offering shall be
made, or such lesser period as may be requested by the lead managing underwriter(s). Any discretionary waiver or termination of the requirements under the foregoing provisions made by the Company or applicable lead managing underwriter(s) shall
apply to each holder of Registrable Securities on a pro rata basis. 
 (b) If any Demand Registration or Shelf Offering involves an
Underwritten Offering, the Company, if requested by the lead managing underwriter(s), will not effect any public sale or distribution of any common equity (or securities convertible into or exchangeable or exercisable for common equity) (other than
a registration statement on Form S-4, Form S-8 or any successor forms thereto) for its own account, subject to customary carve outs, within sixty (60) days after the effective date of such registration, except as may otherwise be agreed
(including as to the length of the restricted period) between the Company and the lead managing underwriter(s) of such Underwritten Offering. 

4.6. Registration Procedures. 

(a) If and whenever the Company is required to use reasonable best efforts to effect the registration of any Registrable Securities under the
Securities Act as provided in Section 4.1, Section 4.2 or Section 4.3, the Company shall as expeditiously as reasonably practicable: 

(i) prepare and file with the Commission a registration statement to effect such registration in accordance with the intended
method or methods of distribution of such securities and thereafter use reasonable best efforts to cause such registration statement to become and remain effective pursuant to the terms of this Article IV; provided, however, that the Company may
discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the registration statement relating thereto; provided, further, that before filing such registration statement or any
amendments thereto, the Company will furnish to the Demand Stockholders, on behalf of all holders of Registrable Securities that are including 

  
 16 

 
Registrable Securities in such registration (such holders of Registrable Securities collectively, the “Selling Stockholders”), their counsel and the lead managing underwriter(s),
if any, copies of all such documents proposed to be filed, which documents will be subject to the review and reasonable comment of such counsel, and other documents reasonably requested by such counsel, including any comment letter from the
Commission, and, if requested by such counsel, provide such counsel reasonable opportunity to participate in the preparation of such registration statement and each prospectus included therein and such other opportunities to conduct a reasonable
investigation within the meaning of the Securities Act, including reasonable access to the Company’s books and records, officers, accountants and other advisors. The Company shall not file any such registration statement or prospectus or any
amendments or supplements thereto with respect to a Demand Registration to which the holders of a majority of Registrable Securities held by the Demand Stockholders, their counsel or the lead managing underwriter(s), if any, shall reasonably object,
in writing, on a timely basis, unless, in the opinion of the Company, such filing is reasonably necessary to comply with Applicable Law; 

(ii) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration statement effective pursuant to the terms of this Article IV, and comply with the provisions of the Securities Act with respect to the disposition of all securities covered
by such registration statement; 
 (iii) if requested by the lead managing underwriter(s), if any, or the holders of a
majority of the then outstanding Registrable Securities being sold in connection with an Underwritten Offering, promptly include in a prospectus supplement or post-effective amendment such information as the lead managing underwriter(s), if any, and
such holders may reasonably request in order to permit the intended method of distribution of such securities and make all required filings of such prospectus supplement or such post-effective amendment as soon as reasonably practicable after the
Company has received such request; provided, however, that the Company shall not be required to take any actions under this Section 4.6(a)(iii) that are not, in the opinion of counsel for the Company, in compliance with Applicable Law; 

(iv) furnish to the Selling Stockholders and each underwriter, if any, of the securities being sold by such Selling
Stockholders such number of conformed copies of such registration statement and of each amendment and supplement thereto, such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any
summary prospectus) and each free writing prospectus (as defined in Rule 405 of the Securities Act) (a “Free Writing Prospectus”) utilized in connection therewith and any other prospectus filed under Rule 424 under the Securities
Act, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholders and underwriter, if any, may reasonably request in order to facilitate the public sale or other disposition of the Registrable
Securities owned by such Selling Stockholders; 

  
 17 

 (v) use reasonable best efforts to register or qualify or cooperate with the
Selling Stockholders, the underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities covered by such registration
statement under such other securities laws or “blue sky” laws of such jurisdictions as the Selling Stockholders and any underwriter of the securities being sold by such Selling Stockholders shall reasonably request, and to keep each such
registration or qualification (or exemption therefrom) effective during the period such registration statement is required to be kept effective and take any other action which may be necessary or reasonably advisable to enable such Selling
Stockholders and underwriters to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Selling Stockholders, except that the Company shall not for any such purpose be required to (A) qualify generally to
do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this clause (v) be obligated to be so qualified, (B) subject itself to taxation in any such jurisdiction or (C) file a general
consent to service of process in any such jurisdiction; 
 (vi) use reasonable best efforts to cause such Registrable
Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if no such securities are so listed, use reasonable best efforts to cause such Registrable Securities to be listed on the New
York Stock Exchange, the NYSE MKT or the NASDAQ Stock Market; 
 (vii) use reasonable best efforts to cause such Registrable
Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be reasonably necessary to enable the Selling Stockholder(s) thereof to consummate the disposition of such
Registrable Securities; 
 (viii) use reasonable best efforts to provide and cause to be maintained a transfer agent and
registrar for all Registrable Securities covered by such registration statement from and after a date not later than the effective date of such registration statement; 

(ix) enter into such agreements (including an underwriting agreement in form, scope and substance as is customary in
underwritten offerings) and use its reasonable best efforts to take all such other actions reasonably requested by the holders of a majority of the Registrable Securities being sold in connection therewith (including those reasonably requested by
the lead managing underwriter(s), if any) to expedite or facilitate the disposition of such Registrable Securities, and in such connection, whether or not an underwriting agreement is entered into and whether or not the registration is an
Underwritten Offering (A) make such representations and warranties to the holders of such Registrable Securities and the underwriters, if any, with respect to the business of the Company and its subsidiaries, and the registration statement,
prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance and scope as are customarily made by issuers in underwritten offerings, and, if true, confirm the same if and when
requested, (B) if an

(2) the Company reasonably determines in good faith that such Records are confidential and so notifies the Inspectors in writing; unless prior to furnishing any such information with respect to clause (1) or (2) such Selling

Section 4.6(a)(ix) cease to be true and correct in any material respect; and (F) upon the happening of any event that makes any statement made in such registration statement or related prospectus or any document incorporated or deemed to
be incorporated therein by reference untrue in any material respect or that requires the making of any changes in such registration statement, prospectus or documents so that, in the case of the registration statement, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the prospectus, it will not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and, at the request of any Selling Stockholder, promptly prepare and furnish to such

shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; 

(xiii) use reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of such registration
statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction at the earliest reasonable practicable date, except that, subject to the

such registration statement a supply of such certificates; 
 (xv) cooperate with each seller of Registrable Securities and
each underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA; and 

(xvi) have appropriate senior officers of the Company participate in reasonable marketing efforts (which marketing efforts will
not, for the avoidance of doubt, include a “road show” requiring such officers to travel outside of the city in which they are primarily located) organized by the underwriters for the offering, marketing or selling of the Registrable
Securities. 
 (b) The Company may require each Selling Stockholder and each underwriter, if any, to furnish the Company in writing such
information regarding each Selling Stockholder or underwriter and the distribution of such Registrable Securities as the Company may from time to time reasonably request in writing to complete or amend the information required by such registration

periods under Section 4.1(c) with respect to the length of time that the effectiveness of a registration statement must be maintained by the amount of time the holder is required to discontinue disposition of such securities. 

(d) With a view to making available to the holders of Registrable Securities the benefits of Rule 144 under the Securities Act and any other

 (ii) use reasonable best efforts to file with the Commission in a timely manner all

the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed or

(c) all messenger, telephone and delivery expenses, (d) all fees and expenses of the Company’s independent certified public accountants and counsel (including with respect to “comfort” letters and opinions),
(e) expenses of the Company incurred in connection with any “road show” and (f) reasonable and documented fees and disbursements of one counsel for all holders of Registrable Securities whose shares are included in a registration
statement, which counsel shall be selected by the Demand Stockholder, shall be borne solely by the Company whether or not any registration statement is filed or becomes effective. In connection with the Company’s performance of its
obligations under this Article IV, the Company will pay its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties and the expense of any annual audit) and the expenses and fees for
listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded. Each Selling Stockholder shall pay its portion
of all underwriting discounts and commissions and transfer taxes, if any, relating to the sale of such Selling Stockholder’s Registrable Securities pursuant to any registration. 

4.8. Miscellaneous. 
 (a)
Not less than seven (7) Business Days before the expected filing date of each registration statement pursuant to this Agreement, the Company shall notify each holder of 

  
 22 

 
Registrable Securities who has timely provided the requisite notice hereunder entitling such holder to register Registrable Securities in such registration statement of the information, documents
and instruments from such holder that the Company or any underwriter reasonably requests in connection with such registration statement, including, to the extent applicable, a questionnaire, custody agreement, power of attorney, lock-up letter,
underwriting agreement and any other documents reasonably required under the terms of such arrangements (the “Requested Information”). If the Company has not received, on or before the third Business Day before the expected filing
date, the Requested Information from such holder, the Company may file the registration statement without including Registrable Securities of such holder. The failure to so include in any registration statement the Registrable Securities of a holder
of Registrable Securities (with regard to that registration statement) shall not result in any liability on the part of the Company to such holder. 

(b) The Company shall not grant any demand, piggyback or shelf registration rights the terms of which are senior to or conflict with the
rights granted to the holders of Registrable Securities hereunder to any other Person without the prior written consent of Demand Stockholders holding a majority of the Registrable Securities then held by all Demand Stockholders. 

4.9. Registration Indemnification. 

(a) The Company agrees, without limitation as to time, to indemnify and hold harmless, to the fullest extent permitted by Applicable Law, each
Selling Stockholder and its Affiliates and their respective officers, directors, members, shareholders, employees, managers, partners, and each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of
the Exchange Act) such Selling Stockholder, from and against all losses, claims, damages, liabilities, costs, expenses (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses), judgments, fines, penalties,
charges and amounts paid in settlement (collectively, the “Losses”), as incurred, arising out of, caused by, resulting from or relating to any untrue statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading and (without limitation of the preceding portions of this Section 4.9(a)) will reimburse each such Selling Stockholder, each of its Affiliates, and each of their
respective officers, directors, members, shareholders, employees, managers, partners, and each such Person who controls each such Selling Stockholder, for any documented legal expenses reasonably incurred in connection with investigating and
defending or settling any such claim, Loss, damage, liability or action, except insofar as the same are caused by any information furnished in writing to the Company by any other party expressly for use therein. 

(b) In connection with any registration statement in which a Selling Stockholder is participating, without limitation as to time, each such
Selling Stockholder shall, severally and not jointly, indemnify the Company, its directors, officers and employees, and each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act)
the Company, from and against all Losses, as incurred, arising out of, caused 

  
 23 

 
by, resulting from or relating to any untrue statement (or alleged untrue statement) of material fact contained in the registration statement, prospectus or preliminary prospectus or Free Writing
Prospectus or any amendment or supplement thereto or any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not
misleading, and (without limitation of the preceding portions of this Section 4.9(b)) will reimburse the Company, its directors, officers and employees and each Person who controls the Company (within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act) for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, Loss, damage, liability or action, in each case solely to the
extent, but only to the extent, that such untrue statement or omission is made in such registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto in reliance upon and in conformity
with written information furnished to the Company by such Selling Stockholder for inclusion in such registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto. Notwithstanding the
foregoing, no Selling Stockholder shall be liable under this Section 4.9(b) for amounts in excess of the net proceeds received by such holder in the offering giving rise to such liability. 

(c) Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification; provided, however, the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been actually and materially prejudiced by such
failure to provide such notice on a timely basis. 
 (d) In any case in which any such action is brought against any indemnified party, and
it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and acknowledging the obligations of the indemnifying party with respect to such proceeding, the indemnifying
party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense
subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision and monitoring (unless (i) such indemnified party reasonably objects to such assumption on the
grounds that there may be defenses available to it which are different from or in addition to the defenses available to such indemnifying party and, as a result, a conflict of interest exists or (ii) the indemnifying party shall have failed
within a reasonable period of time to assume such defense and the indemnified party is or would reasonably be expected to be materially prejudiced by such delay, in either event the indemnified party shall be promptly reimbursed by the indemnifying
party for the expenses incurred in connection with retaining one separate legal counsel (for the avoidance of doubt, for all indemnified parties in connection therewith)). For the avoidance of doubt, notwithstanding any such assumption by an
indemnifying party, the indemnified party shall have the right to employ separate counsel in any such matter and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party except
as provided in the previous sentence. An 

  
 24 

 
indemnifying party shall not be liable for any settlement of an action or claim effected without its consent (which consent shall not be unreasonably withheld, conditioned or delayed). No matter
shall be settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement (x) includes as an unconditional term thereof the giving
by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation, (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf
of any indemnified party and (z) is settled solely for cash for which the indemnified party would be entitled to indemnification hereunder. 

(e) The indemnification provided for under this Agreement shall survive the Transfer of the Registrable Securities and the termination of this
Agreement. 
 (f) If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as
specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such
indemnification but for such reason or reasons, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements
or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, the Persons’ relative knowledge and access to information concerning
the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would not necessarily be
equitable if the amount of such contribution were determined by pro rata or per capita allocation. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution
from any Person who was not found guilty of such fraudulent misrepresentation. Notwithstanding the foregoing, no Selling Stockholder shall be required to make a contribution in excess of the amount received by such Selling Stockholder from its sale
of Registrable Securities in connection with the offering that gave rise to the contribution obligation.
