 WHEREAS, all things necessary (i) to make the Notes, when executed and duly
issued by the Company and authenticated and delivered hereunder, the valid obligations of the Company, and (ii) to make this Indenture a valid agreement of the Company have been done; and 

NOW, THEREFORE, in consideration of the premises and the purchase of the Notes by the Holders thereof, it is mutually covenanted and agreed,
for the equal and proportionate benefit of all Holders, as follows: 
 ARTICLE I 

DEFINITIONS AND INCORPORATION BY REFERENCE 

SECTION 1.1.    Definitions. 

“Acquired EBITDA” means, with respect to any Acquired Entity or Business or any Converted Restricted Subsidiary for any
period, the amount for such period of Consolidated EBITDA of such Acquired Entity or Business or Converted Restricted Subsidiary, as applicable, all as determined on a consolidated basis for such Acquired Entity or Business or Converted Restricted
Subsidiary, as applicable. 
 “Acquired Indebtedness” means Indebtedness (x) of a Person or any of its Subsidiaries
existing at the time such Person becomes a Restricted Subsidiary, (y) 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 or such acquisition or (z) of a Person at the time such Person merges or amalgamates with or into or consolidates or otherwise combines with the Company or any Restricted Subsidiary. Acquired Indebtedness shall be deemed to have been
Incurred, with respect to clause (x) of the preceding sentence, on the date such Person becomes a Restricted Subsidiary, with respect to clause (y) of the preceding sentence, on the date of consummation of such acquisition of assets and, with
respect to clause (z) of the preceding sentence, on the date of the relevant merger, consolidation, amalgamation or other combination. 

“Additional Assets” means: 

(1)    any property or assets (other than Capital Stock) used or to be used by the Company, 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); 
 (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 the Company or a Restricted Subsidiary; or 

(3)    Capital Stock constituting a minority interest in any Person that at such time is a Restricted
Subsidiary. 







 “Additional Notes” has the meaning ascribed to it in the second introductory
paragraph of this Indenture. 
 “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. 

“Air Products” refers to Air Products and Chemicals, Inc. 

“Air Products common stock” refers to the common stock, par value $1.00 per share, of Air Products and Chemicals, Inc. 

“Alternative Currency” means any currency (other than Dollars) that is a lawful currency (other than Dollars) that is readily
available and freely transferable and convertible into Dollars (as determined in good faith by the Company). 
 “Applicable
Premium” means the greater of (A) 1.0% of the principal amount of such Note and (B) on any redemption date, the excess (to the extent positive) of: 

(a)    the present value at such redemption date of (i) the redemption price of such Note at September
30, 2021 (such redemption price (expressed in percentage of principal amount) being set forth in the table under Section 5.7(d) (excluding accrued but unpaid interest, if any)), plus (ii) all required interest payments
due on such Note to and including such date set forth in clause (i) (excluding accrued but unpaid interest, if any), computed upon 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; 

in each case, as calculated by the Company or on behalf of the Company by such Person as the Company shall designate. The Trustee shall have no duty to
calculate or verify the calculations of the Applicable Premium. 
 “Applicable Treasury Rate” means the yield to maturity
at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two (2) Business Days
prior to the redemption date (or in the case of a satisfaction and discharge, two Business Days before the deposit of the redemption funds with the Trustee or Paying Agent) (or, if such statistical release is not so published or available, any
publicly available source of similar market data selected by the Company in good faith)) most nearly equal to the period from the redemption date to September 30, 2021; provided, however, that if the period from the redemption date to
September 30, 2021 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. 
 “Asset
Disposition” means: 
 (a)    the voluntary sale, conveyance, transfer or other disposition,
whether in a single transaction or a series of related transactions, of property or assets (including by way of a Sale and Leaseback Transaction) of the Company or any of its Restricted Subsidiaries (in each case other than Capital Stock of the
Company) (each referred to in this definition as a “disposition”); or 
 (b)    the issuance or
sale of Capital Stock of any Restricted Subsidiary (other than Preferred Stock or Disqualified Stock of Restricted Subsidiaries issued in compliance with Section 3.2 hereof or directors’ qualifying shares and shares
issued to foreign nationals as required under applicable law), whether in a single transaction or a series of related transactions;

 In addition, to the extent not already included in the Consolidated Net Income of such Person and
its Restricted Subsidiaries, notwithstanding anything to the contrary in the foregoing, Consolidated Net Income shall include (i) any expenses and charges that are reimbursed by indemnification or other reimbursement provisions in connection with
any investment or any sale, conveyance, transfer or other disposition of assets permitted hereunder, or, so long as the Company has made a determination that there exists reasonable evidence that such amount will in fact be reimbursed and only to
the extent that such amount is (A) not denied by the applicable payor in writing within 180 days and (B) in fact reimbursed within 365 days of the date of such evidence (with a deduction for any amount so added back to the extent not so reimbursed
within 365 days) and (ii) to the extent covered by insurance (including business interruption insurance) and actually reimbursed, or, so long as the Company has made a determination that there exists reasonable evidence that such amount will in fact

so added back to the extent not so reimbursed within 365 days), expenses with respect to liability or casualty events or business interruption. 

“Consolidated Secured Leverage Ratio” means, with respect to any Person, at any date, the ratio of (i) Secured Indebtedness
of such Person and its Restricted Subsidiaries constituting as of such date of calculation (determined on a consolidated basis in accordance with GAAP) less cash and Cash Equivalents in excess of any restricted cash that would be stated on the
balance sheet of such Person and its Restricted Subsidiaries and held by such Person and its Restricted Subsidiaries as of such date of determination to (ii) LTM EBITDA. For purposes of calculating the Consolidated Secured Leverage Ratio for
the Company (a) at all times prior to the Spin-Off Effective Date pro forma effect will be given to the consummation of the Spin-Off and (b) from and after the Spin-Off Effective Date, such calculation shall be made in respect of the Company
and the Restricted Subsidiaries. 
 In the event that the Company or any Restricted Subsidiary Incurs, repays, repurchases or redeems any
Indebtedness subsequent to the commencement of the period for which the Consolidated Secured Leverage Ratio is being calculated but prior to the event for which the calculation of the Consolidated Secured Leverage Ratio is made (the
“Consolidated Secured Leverage Calculation Date”), then the Consolidated Secured Leverage Ratio shall be calculated giving pro forma effect to such Incurrence, repayment, repurchase or redemption of Indebtedness, or such
issuance, repurchase or redemption of Disqualified Stock or Preferred Stock as if the same had occurred at the beginning of the applicable four-quarter period; provided that the Company may elect pursuant to an Officer’s Certificate delivered
to the Trustee to treat all or any portion of the commitment under any Indebtedness as being Incurred at such time, in which case any subsequent Incurrence of Indebtedness under such commitment shall not be deemed, for purposes of this calculation,
to be an Incurrence at such subsequent time. 
 For purposes of making the computation referred to above, any Investments, acquisitions,
dispositions, mergers, amalgamations, consolidations and disposed or discontinued operations that have been made by the Company or any of its Restricted Subsidiaries, during the reference period or subsequent to the reference period and on or prior
to or simultaneously with the Consolidated Secured Leverage Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, amalgamations, 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 reference period. If since the beginning of such period any Person that
subsequently became a Restricted Subsidiary or was merged or amalgamated with or into the Company or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger,
amalgamation, consolidation or disposed or discontinued operation that would have required adjustment pursuant to this definition, then the Consolidated Secured Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if
such Investment, acquisition, disposition, merger, amalgamation, consolidation or disposed operation had occurred at the beginning of the applicable reference 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 the Company 

  
 -15- 








 
(including cost savings and synergies). 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 Consolidated Secured Leverage Calculation Date had been the applicable rate for the entire reference 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 the Company 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 reference
period except as set forth in the first paragraph of this definition. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered
rate, or other rate, shall be determined to have been based upon the rate actually chosen, or if none, then based upon such optional rate chosen as the Company may designate. 

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 Consolidated Secured Leverage Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligations has
a remaining term in excess of 12 months). 
 Interest on a Capitalized Lease Obligations shall be deemed to accrue at an interest rate
reasonably determined by a responsible financial or accounting officer of the Company 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 on 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 deemed to have been based upon the rate actually chosen, or, if none, then based upon such
optional rate chosen as the Company may designate. 
 For purposes of this definition, any amount in a currency other than U.S. dollars will
be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve month period immediately prior to the date of determination in a manner consistent with that used in calculating Consolidated EBITDA for the
applicable period. 
 “Consolidated Total Indebtedness” means, as of any date of determination, (a) the aggregate
principal amount of Indebtedness for borrowed money (excluding Indebtedness with respect to Cash Management Services and intercompany Indebtedness among the Company and its Restricted Subsidiaries), plus (without duplication) (b) the aggregate
principal amount of Capitalized Lease Obligations, Purchase Money Obligations and unreimbursed drawings under letters of credit of the Company and its Restricted Subsidiaries outstanding on such date, minus (c) the aggregate amount of cash and
Cash Equivalents included in the consolidated balance sheet of the Company and its Restricted Subsidiaries as of the end of the most recent fiscal period for which internal financial statements of the Company are available (provided that, the
cash proceeds of any proposed Incurrence of Indebtedness shall not be included in this clause (c) for purposes of calculating the Consolidated Total Leverage Ratio or the Consolidated Secured Leverage Ratio, as applicable), with such pro forma
adjustments as are consistent with the pro forma adjustments set forth in the definition of “Fixed Charge Coverage Ratio.” For the avoidance of doubt, “Consolidated Total Indebtedness” shall exclude Indebtedness in respect
of any Receivables Facility. For purposes of calculating the Consolidated Total Leverage Ratio or the Consolidated Secured Leverage Ratio, Consolidated Total Indebtedness shall be calculated in the reporting currency of the Company at the spot
rate of exchange pursuant to GAAP on the date of determination as further increased or decreased by the fair value of foreign currency Swap Contracts or other derivative instruments or portions thereof entered into for the purpose of hedging
currency risk related to the principal amount of any Indebtedness on such date of determination, regardless of whether such Swap Contracts or other instruments are recorded under hedge accounting principles in accordance with GAAP. 

“Consolidated Total Leverage Ratio” means, as of any date of determination, the ratio of (x) the sum of (i) Consolidated
Total Indebtedness and (ii) the Reserved Indebtedness Amount, each as of such date to (y) LTM EBITDA.

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 the Company (including cost savings and synergies). 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 reference 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 the Company to be the rate of interest implicit in such

Date. At any time after the Issue Date, the Company may elect to establish that GAAP shall mean the GAAP as in effect on or prior to the date of such election; provided that any such election, once made, shall be irrevocable. At any
time after the Issue Date, the Company 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 the Company to make an election pursuant to the previous sentence; provided that any such election, once made, shall be irrevocable; provided, further, that any calculation or determination in this
Indenture that require the application of GAAP for periods that include fiscal quarters ended prior to the Company’s election to apply IFRS shall remain as previously calculated or determined in accordance with GAAP; provided, further
again, that the Company may only make such election if it also elects to report any subsequent financial reports required to be made by the Company, including pursuant to Section 13 or Section 15(d) of the Exchange Act and

(2)    entered into primarily for purposes of assuring in any other manner the obligee of such Indebtedness
of the payment thereof or to protect such obligee against loss in respect thereof (in whole or in part); 
 provided, however, that the term
“Guarantee” will not include (x) endorsements for collection or deposit in the ordinary course of business or consistent with past practice and (y) standard contractual indemnities or product warranties provided in the ordinary course
of business, and provided, further, that the amount of any Guarantee shall be deemed to be the lower of (i) an amount equal to the stated or determinable amount of the primary obligation in respect of which such Guarantee is made and
(ii) the maximum amount for which such guaranteeing Person may be liable 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

Incurrence);

 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 will be in an aggregate principal amount of $425,000,000. In addition, the Company may issue, from time to time in accordance with
the provisions of this Indenture, Additional Notes (as provided herein). Furthermore, Notes may be authenticated and delivered upon registration of transfer, exchange or in lieu of, other Notes pursuant to
Sections 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. 
 Notwithstanding anything to the contrary contained herein, the Company may not issue
any Additional Notes, unless such issuance is in compliance with Section 3.2. 
 With respect to any Additional
Notes, the Company shall set forth in an Officer’s Certificate or 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
conclusively relying upon, in addition to the Opinion of Counsel and Officer’s Certificate required by Section 12.2, 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 (other than special redemptions or offers to purchase related to a particular transaction or an escrow funding and specific to an issuance of Notes). Holders of the Initial Notes and the Additional Notes will vote and consent
together on all matters to which such Holders are entitled to vote or consent as one class, 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. 
 (b)    The Initial Notes and any Additional Notes (if issued as Restricted
Notes) (the “Additional Restricted Notes”) will be resold initially only to (A) Persons they reasonably believe 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 and purchasers in reliance on Regulation S, in each case, in accordance with the procedure described
herein. Additional Notes offered after the date hereof may be offered and sold by the Company from time to time pursuant to one or more offering or purchase agreements in accordance with applicable law. 

The 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 delivered in the form 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 Section 2.1(d) (the “Rule 144A Global Note”), deposited with the Trustee, as Notes Custodian, duly executed by the Company and
authenticated by the Trustee as hereinafter provided; provided however, the Initial Notes may be initially issued as Definitive Notes substantially in the form of Exhibit C on the date hereof prior to the issuance of a Rule 144A Global
Note. The Rule 144A Global Note may be 

  
 -47- 








 
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 to non-U.S. Persons outside the United States of America (the
“Regulation S Notes”) in reliance on Regulation S shall be delivered in the form of a permanent global Note substantially in the form of Exhibit A including appropriate legends as set forth in
Section 2.1(d) (the “Regulation S Global Note”). Each Regulation S Global Note will be deposited upon authentication with, or on behalf of, the Trustee as Notes Custodian 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”); provided however, the Initial Notes may be initially issued as Definitive Notes substantially in the form of Exhibit C on the date hereof prior to
the issuance of a Regulation S Global Note. 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 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. 
 Investors may hold their interests in the Regulation S Global Note
through organizations other than Euroclear or Clearstream that are participants in DTC’s system or directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants
in such systems. If such interests are held through Euroclear or Clearstream, Euroclear and Clearstream will hold such interests in the applicable Regulation S Global Note on behalf of their participants through customers’ securities
accounts in their respective names on the books of their respective depositaries. Such depositaries, in turn, will hold such interests in the applicable Regulation S Global Note in customers’ securities accounts in the
depositaries’ names on the books of DTC. 
 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. 
 The Rule 144A Global Note and the
Regulation S Global Note are sometimes collectively herein referred to as the “Global Notes.” 
 The principal of (and
premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent designated by the Company 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 Company 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 in accordance with the
Notes Register, or by wire transfer to a 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 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 Section 2.1(d). The Company 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 Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to be bound
by such terms. 

  
 -48- 








 (c)    Denominations. The Notes shall be issuable only in fully
registered form in minimum denominations of $2,000 and any integral multiple 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 Company receives an Opinion of Counsel satisfactory to it to the effect 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 Regulation S Global Note shall bear the following legend on the face thereof: 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE

SECURITY, PRIOR TO THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET FORTH IN RULE 144 PROMULGATED UNDER THE SECURITIES ACT ONLY (A) TO THE ISSUERS OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE
SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A PROMULGATED UNDER THE SECURITIES ACT) THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE
ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S AND IN ACCORDANCE
WITH THE LAWS APPLICABLE TO IT IN THE JURISDICTION IN WHICH SUCH PURCHASE IS MADE, (D) TO AN INSTITUTIONAL “ACCREDITED INVESTOR” WITHIN THE MEANING OF REGULATION D THAT IS ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT, OR FOR THE ACCOUNT OF
SUCH AN ACCREDITED INVESTOR, 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, (E) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE
UNDER THE SECURITIES ACT OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE ISSUERS’ AND THE TRUSTEE’S, OR REGISTRAR’S, AS APPLICABLE, RIGHT PRIOR TO ANY SUCH OFFER,

 -49- 








 BY ITS ACQUISITION OF THIS SECURITY THE HOLDER AND ANY SUBSEQUENT TRANSFEREE HEREOF WILL BE
DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (I) THE PURCHASER IS NOT ACQUIRING OR HOLDING SUCH NOTE OR AN INTEREST THEREIN WITH THE ASSETS OF (A) AN “EMPLOYEE BENEFIT PLAN” (AS DEFINED IN SECTION 3(3) OF ERISA) THAT
IS SUBJECT TO ERISA, (B) A “PLAN” DESCRIBED IN SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), (C) ANY ENTITY DEEMED TO HOLD “PLAN ASSETS” OF ANY OF THE FOREGOING BY
REASON OF AN EMPLOYEE BENEFIT PLAN’S OR PLAN’S INVESTMENT IN SUCH ENTITY OR (D) A GOVERNMENTAL PLAN OR CHURCH PLAN SUBJECT TO SUCH PROVISIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (COLLECTIVELY, “SIMILAR
LAWS”) OR (II) THE ACQUISITION AND HOLDING OF SUCH NOTE BY THE PURCHASER, THROUGHOUT THE PERIOD THAT IT HOLDS SUCH NOTE AND THE DISPOSITION OF SUCH NOTE OR AN INTEREST THEREIN WILL NOT CONSTITUTE OR RESULT IN A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE, A BREACH OF FIDUCIARY DUTY UNDER ERISA OR A VIOLATION OF ANY PROVISIONS OF ANY APPLICABLE SIMILAR LAW. 

IN THE CASE OF THE REGULATION S GLOBAL NOTE:

THIS NOTE 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. BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON NOR IS IT PURCHASING FOR THE ACCOUNT OF
A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT. 

(2)    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 COMPANY 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. 
 (e)    Book-Entry Provisions. (i) This
Section 2.1(e) shall apply only to Global Notes deposited with the Trustee, as Notes Custodian, and for which the applicable procedures of DTC shall govern. 

(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 and (z) bear legends as set forth in Section 2.1(d). 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(e)(4) and 2.1(f).

  
 -50- 








 
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 Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company 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(f) 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 Company 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(f), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company 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. 

(f)    Definitive Notes. Except as provided in Section 2.1(b) and 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 Company that it is
unwilling or unable to continue as depositary for such Global Note or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a
successor depositary is not appointed by the Company within 90 days of such notice, (B) the Company in its sole discretion executes and deliver to the Trustee and Registrar an Officer’s Certificate stating that such Global Note shall
be so exchangeable or (C) an Event of Default has occurred and is continuing and the Registrar has received a written request from DTC. In the event of the occurrence of any of the events specified in the second preceding sentence or in
clause (A), (B) or (C) of the preceding sentence, the Company shall promptly make available to the Registrar 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 Company, other than the initial issuance of the Initial Notes to Air Products described in Section 2.1(b), or evidencing a Note that has been acquired by an affiliate


  
 -51- 








 
in a transaction or series of transactions not involving any public offering, other than the initial issuance of the Initial Notes to Air Products described in Section 2.1(b), must, until
one year after the last date on which either the Company or any affiliate of the Company 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). If required to do so pursuant to any applicable law or regulation, beneficial owners may also obtain Definitive Notes in exchange for their beneficial interests in a Global Note upon written request in
accordance with DTC’s and the Registrar’s procedures. 
 (1)    Any Definitive Note delivered
in exchange for an interest in a Global Note pursuant to Section 2.1(e) 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 Company 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 Company 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 Company 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. 

(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 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 Company by manual or
facsimile 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 $425,000,000, (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 Company signed by one Officer (the “Company
Order”). Such Company 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 Company 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 Company. 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. 

  
 -52- 








 In case the Company 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 Company 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; and the Trustee, upon the Company 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 Company 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 Company 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 Company shall enter into an appropriate agency agreement with any Registrar or
Paying Agent that is not the Trustee. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of each such agent. If the Company
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 Company or any Guarantor may act as Paying Agent,
Registrar or transfer agent; provided, however, that if an Event of Default has occurred and is continuing, then the Registrar, Paying Agent and/or transfer agent shall be the Trustee or such other Person (other than the Company or any
Guarantor) as the Company shall have appointed pursuant to this Section 2.3. 
 The Company initially appoints DTC to act as Depositary with
respect to the Global Notes. The Company initially appoints the Trustee as Registrar and Paying Agent for the Notes. The Company may change 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
Company 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 DTC 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 Company and the Trustee. 

SECTION 2.4.    Paying Agent to Hold Money in Trust. By no later than 11:00 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 Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when
due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or 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 Company or other obligors on the Notes), shall notify the Trustee in writing of any default by the Company or any Guarantor in making any such
payment and shall during the continuance of any default by the Company (or any other obligor upon the Notes) 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 

  
 -53- 








 
for payment in respect of the Notes together with a full accounting thereof. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it as a separate trust fund. The Company 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 Company or a Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy,
reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Notes. 
 SECTION
2.5.    Holder Lists. The Registrar 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 Company, 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 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 Section 2.1(e) and 2.1(f), as applicable, and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and
procedures of DTC, Euroclear and Clearstream. The Registrar shall refuse to register any requested transfer or exchange that does not comply with this paragraph. 

(b)    Transfers of Rule 144A Notes. The following provisions shall apply with respect to
any proposed registration of transfer of a Rule 144A Note prior to the date that is one year after the later of the date of its original issue and the last date on which the Company or any Affiliate of the Company was the owner of such Notes
(or any predecessor thereto): 
 (1)    a registration of transfer of a Rule 144A 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 Company 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 of DTC; 

(2)    [reserved]; and 

(3)    a registration of transfer of a Rule 144A 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 D from the proposed transferee and the delivery of an Opinion of
Counsel, certification and/or other information satisfactory to the Company. 
 (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: 

  
 -54- 








 (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 Company 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; 
 (2)    [reserved]; 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 D 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 Company. 
 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 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) an Initial Note is being transferred pursuant to an effective registration statement, (2) Initial Notes are being exchanged for Notes that do not bear the Restricted Notes Legend in accordance with
Section 2.6(e) or (3) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Company to the effect 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 Company’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 366th calendar day after (1) with respect to the Notes issued on the Issue Date, 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 Company’s satisfaction that the Restricted
Notes Legend shall no longer be required in order to maintain compliance with the Securities Act, the Company may (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 the Company shall have previously otherwise made eligible for exchange with 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 Company and a Company Order requesting the Trustee to authenticate, 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 Company’s written request on no less than five (5) calendar days’ notice prior to the
Automatic Exchange Notice Date, the Trustee shall deliver, at the Company’s expense, the Automatic Exchange Notice to each Holder at such Holder’s address appearing in the register of Holders; provided that the Company has delivered
to the Trustee such Automatic Exchange Notice to be delivered to Holders. 

  
 -55- 








 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 other than pursuant to this Section 2.6(e) shall be permitted without the prior written consent of the
Company. As a condition to any Automatic Exchange, the Company shall provide, and the Trustee shall be entitled to conclusively rely upon, an Officer’s Certificate and Opinion of Counsel to the Company to the effect 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. The Company 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 Company 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 Company’s and Registrar’s written
request. 
 No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company 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 Sections 2.2, 2.6, 2.11, 2.13, 3.5, 5.6 or 9.5). 
 The Company (and
the Registrar) shall not be required to register the transfer of or exchange of any Note (A) for a period beginning (1) 15 calendar days before the sending of a notice of an offer to repurchase or redeem Notes and ending at the close
of business on the day of such sending or (2) 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.

 Prior to the due presentation for registration of transfer of any Note, the Company, 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 Company, the Trustee, the
Paying Agent or the Registrar shall be affected by notice to the contrary. 
 Any Definitive Note authenticated pursuant to the transactions
described in Section 2.1(b) or delivered in exchange for an interest in a Global Note pursuant to Section 2.1(f) shall, except as otherwise provided by Section 2.6(d), bear the applicable
legend 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. 

  
 -56- 








 (h)    No Obligation of the Trustee. (1) Neither the Trustee nor
the Registrar shall have any 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 subject to the
applicable rules and procedures of DTC. 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. 

Neither the Trustee nor the Registrar shall have any 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 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 Company 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 Company 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 Company 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”), (c) satisfies any other reasonable requirements of the Trustee and (d) provides an indemnity bond, as more fully described below; 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 Company 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
Company or the Trustee in connection therewith. Such Holder shall furnish security or indemnity sufficient in the judgment of the (i) Trustee to protect the Trustee and (ii) the Company to protect the Company, from any loss which any
of them may suffer if a Note is replaced, and, in the absence of notice to the Company, any Guarantor or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute, and upon receipt of a Company 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 Company in
its discretion may, instead of issuing a new Note, pay such Note. 

  
 -57- 








 Upon the issuance of any new Note under this Section 2.11, the Company
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.

 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 Company, 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 Company or an Affiliate of the Company holds the Note; provided, however, that (i) for purposes of
determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 12.4 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 Company or an Affiliate of the Company 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 Company 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 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, 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 Company 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 Company considers appropriate for temporary Notes. Without unreasonable delay, the Company 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 Company 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 Company shall execute, and the Trustee shall, upon receipt of a Company 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 Company may, at any time, 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 by any Holder. The Trustee and no one else shall promptly cancel all Notes
delivered or surrendered by the Company or any Holder 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). At the Company’s written request, certification of the disposition of all canceled Notes will be delivered to the Company. If the Company or any


  
 -58- 








 
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 Company 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 Registrar (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 on the regular record date for such payment at the
office or agency of the Company 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 Company, at its election, as
provided in clause (a) or (b) below: 
 (a)    The Company 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 business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed
in the following manner. The Company 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 Company 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 in this
Section 2.15(a). Thereupon the Company shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 20 calendar days and not
less than 15 calendar days prior to the Special Interest Payment Date and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in
writing of such Special Record Date, and in the name and at the expense of the Company, 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 12.1, not less than 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 Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the provisions in Section 2.15(b). 

(b)    The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this
Section 2.15(b), such manner of payment shall be deemed practicable by the Trustee.

 Subject to the foregoing provisions of this Section 2.15, each Note
delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 

SECTION 2.16.    CUSIP and ISIN Numbers. 

The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers and, if so, the Trustee shall use “CUSIP and
“ISIN” numbers in notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Notes or as contained in any notice of a redemption 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 Company shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

 -63- 








 (1)    subject to clause (3) below, 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) or (b), the Company, in its sole discretion, shall divide, classify, and may from time to time
reclassify, such item of Indebtedness and will only be required to include the amount and type of such Indebtedness in Section 3.2(a) or one of the clauses of Section 3.2(b); 

(2)    additionally, all or any portion of any item of Indebtedness may later be reclassified as having
been Incurred pursuant to any type of Indebtedness described in Section 3.2(a) or (b) so long as such Indebtedness is permitted to be Incurred pursuant to such provision and any related Liens are permitted to be
Incurred at the time of reclassification; 
 (3)    all Indebtedness outstanding on the Issue Date under
the Credit Agreement shall be deemed Incurred on the Issue Date under Section 3.2(b)(1); 

(4)    in the case of any Refinancing Indebtedness, when measuring the outstanding amount of such
Indebtedness such amount shall not include the aggregate amount of fees, underwriting discounts, accrued and unpaid interest, premiums (including, without limitation, tender premiums) and other costs and expenses (including, without limitation,
original issue discount, upfront fees or similar fees) Incurred in connection with such refinancing; 

(5)    Guarantees of, or obligations in respect of letters of credit, bankers’ acceptances or other
similar instruments relating to, or Liens securing, Indebtedness that is otherwise included in the determination of a particular amount of Indebtedness shall not be included; 

(6)    if obligations in respect of letters of credit, bankers’ acceptances or other similar
instruments are Incurred pursuant to any Credit Facility and are being treated as Incurred pursuant to Section 3.2(a) or any clause of Section 3.2(b) and the letters of credit, bankers’ acceptances or other
similar instruments relate to other Indebtedness, then such other Indebtedness shall not be included; 

(7)    the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or
Preferred Stock of a Restricted Subsidiary, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof; 

(8)    Indebtedness permitted by this covenant need not be permitted solely by reference to one provision
permitting such Indebtedness; the Company will be entitled to divide and classify an item of Indebtedness in more than one of the categories of Indebtedness described in the second paragraph of this covenant without giving pro forma effect to the
Indebtedness Incurred pursuant to any other clause or paragraph above (or any portion thereof) when calculating the amount of Indebtedness that may be Incurred pursuant to any such clause or paragraph (or any portion thereof); 

(9)    in the event that the Company or a Restricted Subsidiary enters into or increases commitments under
a revolving credit facility, the Fixed Charge Coverage Ratio or the Consolidated Secured Leverage Ratio, as applicable, for borrowings and reborrowings thereunder (and including issuance and creation of letters of credit and bankers’
acceptances thereunder) will, at the Company’s option as elected on the date the Company or a Restricted Subsidiary, as the case may be, enters into or increases such commitments, either (a) be determined on the date of such revolving credit
facility or such increase in commitments (assuming that the full amount thereof has been borrowed as of such date), and, if such Fixed Charge Coverage Ratio or the Consolidated Secured Leverage Ratio, as applicable, test is satisfied with respect
thereto at such time, any borrowing or reborrowing thereunder (and the issuance and creation of letters of credit and bankers’ acceptances thereunder) will be permitted under this covenant irrespective of the Fixed Charge Coverage Ratio or the
Consolidated Secured Leverage Ratio, as applicable, at the time of any borrowing or reborrowing (or issuance or creation of letters of credit or bankers’ acceptances thereunder) (the committed amount permitted to be borrowed or reborrowed (and
the issuance and creation of letters of credit and bankers’ acceptances) on a date pursuant to the operation of this clause (a) shall be the “Reserved Indebtedness Amount” as of such date for purposes of the Fixed Charge
Coverage Ratio or the Consolidated Secured Leverage Ratio, as applicable) or (b) be determined on the date such amount is borrowed pursuant to any such facility or increased commitment; 

  
 -64- 








 (10)    in the event that the Company or a Restricted
Subsidiary (x) incurs Indebtedness to finance an acquisition or (y) assumes Indebtedness of Persons that are acquired by the Company or any Restricted Subsidiary or merged into the Company or a Restricted Subsidiary in accordance with the terms
of this Indenture, the date of determination of the Fixed Charge Coverage Ratio or the Consolidated Secured Leverage Ratio, as applicable, shall, at the option of the Company, be the date that a definitive agreement for such acquisition, purchase,
merger or consolidation is entered into and the Fixed Charge Coverage Ratio or the Consolidated Secured Leverage Ratio, as applicable, shall be calculated giving pro forma effect to such acquisition, purchase, merger or consolidation and the other
transactions to be entered into in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) consistent with the definition of the Fixed Charge Coverage Ratio or the Consolidated Secured Leverage Ratio, as
applicable, and, for the avoidance of doubt, (A) if any such ratios are exceeded as a result of fluctuations in such ratio (including due to fluctuations in the Consolidated EBITDA of the Company or the target company) at or prior to the
consummation of the relevant acquisition, purchase, merger or consolidation such ratios will not be deemed to have been exceeded as a result of such fluctuations solely for purposes of determining whether such acquisition, purchase, merger or
consolidation and any related transactions are permitted hereunder and (B) such ratios shall not be tested at the time of consummation of such acquisition, purchase, merger or consolidation or related transactions; provided, further, that if
the Company elects to have such determinations occur at the time of entry into such definitive agreement, (i) any such transaction shall be deemed to have occurred on the date the definitive agreement is entered into and to be outstanding thereafter
for purposes of calculating any ratios under this Indenture after the date of such agreement and before the earlier of the date of consummation of such acquisition, purchase, merger or consolidation or the date such agreement is terminated or
expires without consummation of such acquisition, purchase, merger or consolidation and (ii) to the extent any covenant baskets were utilized in satisfying any covenants, such baskets shall be deemed utilized until the earlier of the date of
consummation of such acquisition, purchase, merger or consolidation or the date such agreement is terminated or expires without consummation of such acquisition, purchaser, merger or consolidation, but any calculation of Consolidated EBITDA for
purposes of other incurrences of Indebtedness or Liens or making of Restricted Payments (not related to such acquisition) shall not reflect such acquisition, purchase, merger or consolidation until it has been consummated; and 

(11)    the amount of Indebtedness issued at a price that is less than the principal amount thereof
will be equal to the amount of the liability in respect thereof determined on the basis of GAAP. 
 (d)    Accrual of
interest, accrual of dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the payment of interest or dividends 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, will 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 as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 3.2,
the Company shall be in default of this Section 3.2). 
 (f)    For purposes of determining
compliance with any Dollar-denominated restriction on the Incurrence of Indebtedness, the Dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect
on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first incurred (whichever yields the lower Dollar equivalent), in the case of revolving credit debt; provided, that if such Indebtedness is Incurred
to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such
refinancing, such Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed (a) the principal amount of such Indebtedness


  
 -65- 








 
being refinanced plus (b) the aggregate amount of fees, underwriting discounts, accrued and unpaid interest, premiums (including, without limitation, tender premiums) and other costs and expenses
(including, without limitation, original issue discount, upfront fees or similar fees) Incurred in connection with such refinancing. 

(g)    Notwithstanding any other provision of this Section 3.2, the maximum amount of
Indebtedness that the Company 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 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. The principal amount of any non-interest bearing Indebtedness or other discount security constituting Indebtedness at any date shall be the principal amount
thereof that would be shown on a balance sheet of the Company dated such date prepared in accordance with GAAP. 

(h)    The Company shall not, and shall not permit any Guarantor to, directly or indirectly, Incur any Indebtedness
(including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Company 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 the Company or such Guarantor, as the case may be; provided that for purposes of this Indenture,
(1) unsecured Indebtedness shall not be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured, (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, (3) Indebtedness of such Person which is not guaranteed shall not be treated as
subordinated or junior to Indebtedness that is guaranteed merely because of such guarantee and (4) Indebtedness under any Secured Indebtedness shall not be treated as subordinated because of the application of the waterfall or other
payment-ordering or collateral-sharing provisions affecting such Secured Indebtedness. 
 SECTION 3.3.    Limitation
on Restricted Payments. 
 (a)    The Company shall not, and shall not permit any of its Restricted Subsidiaries,
directly or indirectly, to: 
 (1)    declare or pay any dividend or make any distribution on or in
respect of the Company’s or any Restricted Subsidiary’s Capital Stock (including, without limitation, any such payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except: 

(i)    dividends or distributions payable in Capital Stock of the Company (other than Disqualified Stock)
or in options, warrants or other rights to purchase such Capital Stock; or 
 (ii)    dividends or
distributions payable to the Company or a Restricted Subsidiary (and, in the case of the Company or any such Restricted Subsidiary making such dividend or distribution, to holders of its Capital Stock other than the Company or another Restricted
Subsidiary on no more than a pro rata basis). 
 (2)    purchase, repurchase, redeem, retire or

of such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing. 
 SECTION
3.5.    Limitation on Sales of Assets and Subsidiary Stock. 
 (a)    The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: 

(1)    in accordance with the Transactions in a manner consistent in all material respects with the
disclosures set forth in the Offering Memorandum; 
 (2)    the Company 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), as determined in good faith by the Company, 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); 
 (3)    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 75.0% of the consideration from such Asset Disposition, received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and

 (4)    an amount equal to 100.0% of the Net Available Cash from such Asset Disposition is applied:

 (i)    to the extent the Company 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 any Secured Indebtedness (in each case, other than Indebtedness owed to the Company or any Restricted Subsidiary), including
Indebtedness under the Credit Agreement (or any Refinancing Indebtedness in respect thereof) within 365 days from 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), the Company 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 Pari Passu Indebtedness; provided further that, to the extent the Company redeems, repays or repurchases Pari Passu Indebtedness pursuant to this clause (B), the Company shall
equally and ratably reduce Obligations under the Notes as provided under Section 5.7, through open-market purchases (to the extent such purchases are at or above 100.0% of the
principal amount thereof) or by making an offer (in accordance with the procedures set forth 

  
 -74- 








 
below for an Asset Disposition Offer) to all Holders to purchase their Notes at 100.0% 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 
 (ii)    to the extent the Company 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 equal to the amount of Net Available Cash received by the Company or another Restricted
Subsidiary) within 365 days of the receipt of such Net Available Cash; a binding commitment shall be treated as a permitted application of the Net Available Cash from the date of such commitment until the 12-month anniversary of the date of the
receipt of such Net Available Cash; provided that, in the event such binding commitment is later cancelled or terminated for any reason before such Net Available Cash is so applied, then such Net Available Cash shall constitute Excess
Proceeds unless the Company or such Restricted Subsidiary enters into another binding commitment (a “Second Commitment”) within six months of such cancellation or termination of the prior binding commitment; provided,
further, that the Company or such Restricted Subsidiary may only enter into a Second Commitment under the foregoing provision one time with respect to each Asset Disposition and to the extent such Second Commitment is later cancelled or
terminated for any reason before such Net Available Cash is applied or such Net Available Cash is not applied within 180 days of such Second Commitment, then such Net Available Cash shall constitute Excess Proceeds; 

provided that, pending the final application of the amount of any such Net Available Cash in accordance with clause (i) or clause (ii) above,
the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise use such Net Available Cash in any manner not prohibited by this Indenture. 

(b)    The amount of any Net Available Cash from Asset Dispositions that is not applied or invested or committed to be
applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds” under this Indenture. On the 366th day after the receipt of such Net Available Cash, if the aggregate amount of Excess
Proceeds under this Indenture exceeds $50.0 million, the Company will within 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 Company elects, to all holders of other outstanding Pari Passu Indebtedness, to purchase the maximum principal amount of Notes and any such Pari Passu Indebtedness to which the Asset Disposition Offer applies that may be purchased out of the
Excess Proceeds, at an offer price in respect of the Notes in an amount equal to 100.0% of the principal amount of the Notes and Pari Passu 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 Pari Passu 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 Company will deliver notice of such Asset Disposition Offer electronically or by first-class mail, with a copy to the Trustee, the Paying Agent and each Holder of Notes at the address of such Holder appearing in the security
register or otherwise in accordance with the applicable procedures of DTC, 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 will be no earlier than 15 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. The Company may satisfy the
foregoing obligations with respect to any Net Available Cash from an Asset Disposition by making an Asset Disposition Offer with respect to all Net Available Cash prior to the expiration of the relevant 365 days (or such longer period provided
above) or with respect to any unapplied Excess Proceeds. 
 (c)    To the extent that the aggregate amount of Notes and
Pari Passu Indebtedness so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company 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 Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the
Company shall allocate the Excess Proceeds among the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Indebtedness; provided that no Notes or
other Pari Passu Indebtedness will be selected and purchased in an unauthorized denomination. Upon completion of any Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero. Additionally, the Company may, at its


  
 -75- 








 
option, make an Asset Disposition Offer using proceeds from any Asset Disposition at any time after the consummation of such Asset Disposition. Upon consummation or expiration of any Asset
Disposition Offer, any remaining Net Available Cash shall not be deemed Excess Proceeds and the Company may use such Net Available Cash for any purpose not prohibited by this Indenture. To the extent that any portion of Net Available Cash
payable in respect of the Notes is denominated in a currency other than Dollars, the amount thereof payable in respect of the Notes shall not exceed the net amount of funds in Dollars that is actually received by the Company upon converting such
portion into Dollars. Pending the final application of any Net Available Cash, the holder of such Net Available Cash may apply such Net Available Cash temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise
invest such Net Available Cash in any manner not prohibited by this Indenture. 
 (d)    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 (a “Foreign Disposition”) is (x) prohibited or delayed by applicable local law, (y) restricted by applicable organizational documents or any agreement or (z)
subject to other onerous organizational or administrative impediments 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 covenant, and such
amounts may be retained by the applicable Foreign Subsidiary so long, but only so long, as the applicable local law documents or agreements will not permit repatriation to the United States (the Company hereby agreeing to use reasonable efforts (as
determined in the Company’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, promptly take all actions
reasonably required by the applicable local law, applicable organizational impediments or other impediment 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, applicable organizational impediment or other impediment, 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 (net of additional Taxes payable or reserved against as a result thereof) (whether or not such repatriation actually occurs) in compliance with this Section 3.5; and

 (ii)    to the extent that the Company has determined in good faith that repatriation of any of or
all the Net Available Cash of any Foreign Disposition would have a material adverse Tax, the Net Available Cash, to the extent of the amount of such Tax, will not be required to be applied in accordance with this Section 3.5. The
non-application 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. 

(e)    For the purposes of Section 3.5(a)(3) hereof, the following will be deemed
to be cash: 
 (1)    the assumption by the transferee of Indebtedness or other liabilities contingent or
otherwise of the Company or a Restricted Subsidiary (other than Subordinated Indebtedness of the Company or a Guarantor) and the release or indemnification of the Company or such Restricted Subsidiary from all liability on such Indebtedness or other
liability in connection with such Asset Disposition; 
 (2)    securities, notes or other obligations
received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days following the closing of such Asset Disposition; 

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

(4)    consideration consisting of Indebtedness of the Company (other than Subordinated Indebtedness)
received after the Issue Date from Persons who are not the Company or any Restricted Subsidiary; and 

  
 -76- 








 (5)    any Designated Non-Cash Consideration received by the
Company 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 covenant that is
at that time outstanding, not to exceed the greater of (a) $25.0 million and (b) 3.0% of Total Assets (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). 
 (f)    To the extent that the provisions of
any securities laws, rules or regulations, including Rule 14e-1 under the Exchange Act, conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws, rules and regulations and shall not be deemed to
have breached its obligations described in this Indenture by virtue thereof. 
 (g)    The provisions of this Indenture
relative to the Company’s obligation to make an offer to repurchase the Notes as a result of an Asset Disposition may be waived or modified with the written consent of the Holders of a majority in principal amount of the then outstanding Notes.

 SECTION 3.6.    Limitation on Liens. The Company shall not, and shall not permit any Guarantor 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 the Company
or any Guarantor, 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 or the Guarantees are ratably secured or secured on a senior basis,

 except that the foregoing shall not apply to any Liens securing the Notes and the related Guarantees. 

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by its terms that such Lien
shall be automatically and unconditionally released and discharged (i) upon the release and discharge of the Initial Lien or (ii) any sale, exchange or transfer to any person not an Affiliate of the Company of the property or assets secured by
the Initial Lien, or of all of the Capital Stock held by the Company or any Restricted Subsidiary in, or all or substantially all of the assets of, any Guarantor creating such Initial Lien. 

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)    The Company shall not permit any of its Wholly Owned Restricted Subsidiaries that are not Foreign Subsidiaries or
Excluded Subsidiaries, to guarantee or become a borrower under the Credit Agreement, unless: 

(1)    such Restricted Subsidiary within 60 days executes and delivers a supplemental indenture to this
Indenture providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Company or any 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 Guarantee of the Notes; and 

  
 -77- 








 (2)    such Restricted Subsidiary waives and will not in any
manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against the Company or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary
under its Guarantee until payment in full of Obligations under this Indenture. 
 provided that this Section 3.7 shall not
be applicable (i) to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary, or
(ii) in the event that the Guarantee of the Company’s obligations under the Notes or this Indenture by such Subsidiary would not be permitted under applicable law. 

(b)    The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a
Guarantor to become a Guarantor, in which case, such Subsidiary shall not be required to comply with the 60-day period described in Section 3.7(a). 

(c)    If any Guarantor becomes an Immaterial Subsidiary, the Company shall have the right, by execution and delivery of a
supplemental indenture to the Trustee, to cause such Immaterial Subsidiary to cease to be a Guarantor, subject to the requirement described in the first paragraph above that such Subsidiary shall be required to become a Guarantor if it ceases to be
an Immaterial Subsidiary (except that if such Subsidiary has been properly designated as an Unrestricted Subsidiary it shall not be so required to become a Guarantor or execute a supplemental indenture); provided, further, that such
Immaterial Subsidiary shall not be permitted to Guarantee the Credit Agreement or other Indebtedness of the Company or the other Guarantors, unless it again becomes a Guarantor. 

SECTION 3.8.    Limitation on Affiliate Transactions. 

(a)    The Company shall not, and shall not permit any Restricted Subsidiary to 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 the Company (an “Affiliate Transaction”) involving aggregate value in excess of $20.0 million, unless: 

(1)    the terms of such Affiliate Transaction taken as a whole are not materially less favorable to the
Company 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 $40.0 million, the Company delivers to the Trustee, a resolution adopted by the majority of the Board of Directors (including a majority of the Disinterested Directors) approving such Affiliate
Transaction and an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) above. 

(b)    The provisions of 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 the Company, any Restricted
Subsidiary or any Parent Entity, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits or consultants’ plans (including
valuation, health, 

  
 -78- 








 
insurance, deferred compensation, severance, retirement, savings or similar plans, programs or arrangements) or indemnities provided on behalf of former, current or future officers, employees,
directors or consultants of the Company, any Restricted Subsidiary or any Parent Entity approved by the Board of Directors or senior management of the Company, any Restricted Subsidiary or any Parent Entity, as applicable; 

(3)    any Management Advances and any waiver or transaction with respect thereto; 

(4)    (a) any transaction between or among the Company and any Restricted Subsidiary (or entity that
becomes a Restricted Subsidiary as a result of such transaction), or between or among Restricted Subsidiaries and (b) any merger or consolidation with any Parent Entity, provided that such Parent Entity shall have no material liabilities and
no material assets other than cash, Cash Equivalents and the Capital Stock of the Company or another Parent Entity with no material liabilities and no material assets other than cash, Cash Equivalents and the Capital Stock of the Company or another
Parent Entity and such merger or consolidation is otherwise consummated in compliance with this Indenture; 

(5)    the payment of compensation, fees and reimbursement of expenses to, and customary indemnities
(including under customary insurance policies) and employee benefit and pension expenses provided on behalf of, former, current or future directors, officers, consultants or employees of the Company, any Parent Entity or any Restricted Subsidiary
(whether directly or indirectly and including through any Controlled Investment Affiliate of such directors, officers or employees); 

(6)    the entry into and performance of obligations of the Company or any of its Restricted Subsidiaries
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 (or, if entered into in connection with the Spin-Off and not in effect on
the Issue Date, as in effect on the Spin-Off Effective Date), 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 covenant or to the
extent not more disadvantageous to the Holders in any material respect when taken as a whole; 

(7)    any customary transaction with a Receivables Subsidiary including a Securitization Repurchase
Obligation and sales of accounts receivable, or participations therein, in connection with any Receivables Facility; 

(8)    transactions with customers, clients, joint venture partners, 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 the Company or the relevant Restricted Subsidiary in the reasonable determination of the Board of Directors or the senior
management of the Company 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)    transactions with any other Person that is an Affiliate of the Company solely because the Company
owns, directly or through a Restricted Subsidiary, an equity interest in, or controls, such Person; 

(10)    issuances or sales of Capital Stock (other than Disqualified Stock or Designated Preferred Stock)
of the Company or options, warrants or other rights to acquire such Capital Stock and the granting and performance of registration and other customary rights in connection therewith or any contribution to capital of the Company or any Restricted
Subsidiary; 
 (11)    any transactions (a) pursuant to the Transactions, the Transaction Agreements and
any actions pursuant thereto or contemplated thereby, including the payment of all costs and expenses (including all legal, accounting and other professional fees and expenses) related to the Transactions, (b) with Air Products or any of its
Affiliates pursuant to the contracts or agreements described in the Offering Memorandum under the caption “Our Relationship with Air Products Following the Spin-Off”, or (c) in the case of each of clauses (a) and (b), any amendment,
modification, or supplement thereto or replacement 

  
 -79- 








 
thereof, as long as such agreement or arrangement, as so amended, modified, supplemented or replaced, taken as a whole, is not materially more disadvantageous to the Company and its Restricted
Subsidiaries than the original agreement or arrangement in existence on the Issue Date (or if such agreement or contract is not in effect on the Issue Date or in the case of the Transaction Agreements, their respective dates); 

(12)    transactions in which the Company or any Restricted Subsidiary, as the case may be, delivers to the
Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or meets the requirements of Section 3.8(a)(1); 

(13)    the existence of, or the performance by the Company or any Restricted Subsidiary of its obligations
under the terms of, any equityholders agreement (including any registration rights agreement or purchase agreements related thereto) to which it is party as of the Issue Date and any similar agreement that it may enter into thereafter;
provided, however, that the existence of, or the performance by the Company or any Restricted Subsidiary of its obligations under any future amendment to the equityholders’ agreement or under any similar agreement entered into
after the Issue Date will only be permitted under this clause (13) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous to the Holders in any material respect; 

(14)    any purchase by or Issuance to the Company’s Affiliates of Indebtedness or Disqualified Stock
of the Company or any of its Restricted Subsidiaries the majority of which Indebtedness or Disqualified Stock is purchased by or Issued to Persons who are not the Company’s Affiliates; provided that such purchases by or Issuances to the
Company’s Affiliates are on terms no less favorable to the Company and its Restricted Subsidiaries as such purchases by or Issuances to such Persons who are not the Company’s Affiliates; 

(15)    (i) investments by Affiliates in securities of the Company or any of its Restricted
Subsidiaries (and payment of reasonable out-of-pocket expenses incurred by such Affiliates in connection therewith) so long as the investment is being offered by the Company or such Restricted Subsidiary generally to other non-affiliated third party
investors on the same or more favorable terms and (ii) payments to Affiliates in respect of securities of the Company or any of its Restricted Subsidiaries contemplated in the foregoing clause (i) or that were acquired from Persons other than
the Company and its Restricted Subsidiaries, in each case, in accordance with the terms of such securities; 

(16)    payments by any Parent Entity, the Company and the Restricted Subsidiaries pursuant to any tax
sharing agreements or other equity agreements in respect of Related Taxes among any such Parent Entity, the Company and the Restricted Subsidiaries on customary terms to the extent attributable to the ownership or operation of the Company and its
Subsidiaries; 
 (17)    payments, Indebtedness and Disqualified Stock (and cancellation of any thereof)

or agreement or any stock subscription or shareholder agreement; and any employment agreements, stock option plans and other compensatory arrangements (and any successor plans thereto) and any supplemental executive retirement benefit plans or

arrangement or similar arrangement entered into in connection with or in contemplation of the disposition of assets or equity interests in any Restricted Subsidiary permitted under Section 3.5 or entered into with any Business Successor, in
each case, that the Company determines in good faith is either fair to the Company or otherwise on customary terms for such type of arrangements in connection with similar transactions; 

(20)    transactions entered into by an Unrestricted Subsidiary with an Affiliate prior to the day such
Unrestricted Subsidiary is redesignated as a Restricted Subsidiary as described under the caption “—Designation of Restricted and Unrestricted Subsidiaries;” and

SECTION 3.9.    Change of Control. 

(a)    If a Change of Control occurs, unless the Company has previously or substantially concurrently therewith delivered
a redemption notice with respect to all of the outstanding Notes and all conditions to such redemption, other than the deposit of funds with the Trustee, have been satisfied as set forth under Section 5.7(a) or
Section 5.7(d), the Company shall make an offer to purchase all of the Notes pursuant to the offer (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal
to 101.0% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to but excluding the date of repurchase; provided that if the repurchase date is after the record date but on or before the related interest payment
date, then Holders of the Notes who hold as of the record date will receive interest on the repurchase date. Within 30 days following any Change of Control, the Company will deliver or cause to be delivered notice of such Change of Control
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 of DTC, with the following
information: 
 (1)    that a Change of Control Offer is being made pursuant to this
Section 3.9, and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment by the Company; 

(2)    the purchase price and the purchase date, which will be no earlier than 15 days nor later than
60 days from the date such notice is delivered (the “Change of Control Payment Date”); 

(3)    that any Note not properly tendered will remain outstanding and continue to accrue interest; 

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

(5)    that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be
required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of
business on the third Business Day preceding the Change of Control Payment Date; 
 (6)    that Holders
will be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided that the Paying Agent receives, not later than the close of business on the second Business Day prior to the
expiration date of the Change of Control Offer, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its
tendered Notes and its election to have such Notes purchased; 
 (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. The unpurchased portion of the Notes must be equal to at least $2,000 or any
integral multiple of $1,000 in excess of $2,000; 

  
 -81- 








 (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 Company, 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 mail (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 minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 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 repurchase date to the Person in whose name a Note is registered at the close of business on such record
date. 
 (b)    On the Change of Control Payment Date, the Company 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 with the Paying Agent an amount 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 Company. 

(c)    The Company will not be required to make a Change of Control Offer following a Change of Control if (x) 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 Company and purchases all Notes validly
tendered and not withdrawn under such Change of Control Offer or (y) a notice of redemption of all outstanding Notes has been given pursuant to Section 5.7 hereof 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 due to the failure of a condition precedent contained in the applicable redemption notice to be satisfied. 

(d)    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. 
 (e)    [Reserved] 

(f)    While the Notes are in global form and the Company makes an offer to purchase all of the Notes pursuant to the
Change of Control Offer, a Holder may exercise its option to elect for the purchase of the Notes through the facilities of DTC, subject to its rules and regulations. 

(g)    The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws, rules and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer. To the extent that the provisions of any
securities laws, rules or regulations conflict with the provisions of this Indenture, the Company 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)    Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, from and after the Issue Date, the Company shall furnish to the
Trustee, within 15 days after the time periods specified below: 
 (1)    within 100 days (120 days
in the case of the fiscal year ending September 30, 2016) after the end of each fiscal year, all financial 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 the Company’s independent registered public accounting firm; 

(2)    within 55 days (60 days in the case of the first three fiscal quarters after the Issue Date)

(3)    promptly after the occurrence of any of the following events, all current reports that would be
required to be filed with the SEC on Form 8-K or any successor or comparable form (if the Company had been a reporting company under Section 15(d) of the Exchange Act); provided, that the foregoing shall not obligate the Company to make
available (i) any information otherwise required to be included on a Form 8-K regarding the occurrence of any such events if the Company determines in its good faith judgment that such event that would otherwise be required to be disclosed is not
material to the Holders of the Notes or the business, assets, operations, financial positions or prospects of the Company and its Restricted Subsidiaries taken as a whole, (ii) a summary of the terms of, any employment or compensatory arrangement,
agreement, plan or understanding between the Company (or any of its Subsidiaries) and any director, manager or executive officer of the Company (or any of its Subsidiaries) or (iii) copies of any agreements, financial statements or other items
that would be required to be filed as exhibits to a current report on Form 8-K:

 (B)    significant acquisitions or dispositions; 

(C)    bankruptcy;

in each case, in a manner that complies in all material respects with the requirements specified in such form, except as described above or below and subject
to exceptions consistent with the presentation of information in the Offering Memorandum; provided, however, that the Company shall not be required to (i) comply with Regulation G under the Exchange Act or Item 10(e) of Regulation S-K

 -83- 








 
Memorandum or (iii) provide separate financial statements or other information contemplated by Rule 3-09 or Rule 3-10 of Regulation S-X, or in each
case any successor provisions. In addition, notwithstanding the foregoing, the Company will not be required to (i) comply with Sections 302, 906 and 404 of the Sarbanes-Oxley Act of 2002, as amended, or (ii) otherwise furnish any
information, certificates or reports required by Items 307 or 308 of Regulation S-K. 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, the Company will be deemed to have satisfied its obligations with respect thereto at such time and any Default with respect thereto shall be deemed to have been cured; provided that such cure shall not
otherwise affect the rights of the Holders under Section 6.1 hereof if Holders of at least 30.0% in principal amount of the then total outstanding Notes have declared the principal, premium, if any, interest and any other monetary
obligations on all the then outstanding 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 Company shall
agree that, for so long as any Notes are outstanding, it shall 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)    If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries and such Unrestricted
Subsidiaries hold in the aggregate more than 5.0% of the Total Assets of the Company, then the annual and quarterly financial information required by Section 3.10(a)(1) and (2) will 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 the
Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 

(c)    Substantially concurrently with the furnishing or making such information available to the Trustee pursuant to the
immediately preceding paragraph, the Company shall also use its commercially reasonable efforts to post copies of such information required by the immediately preceding paragraph on a website (which may be nonpublic and may be maintained by the
Company or a third party) to which access will be given to the Holders, prospective investors in the Notes (which prospective investors shall be limited to “qualified institutional buyers” within the meaning of Rule 144A of the Securities
Act or non-U.S. persons (as defined in Regulation S under the Securities Act) that certify their status as such to the reasonable satisfaction of the Company), and securities analysts and market making financial institutions that are, in the case of
securities analysts and market making financial institutions, reasonably satisfactory to the Company. To the extent the Company determines in good faith that it cannot make such reports available in the manner described in the preceding
sentence after the use of its commercially reasonable efforts, the Company shall furnish such reports to the Holders of the Notes, upon their request. The Company may condition the delivery of any such reports to such Holders, prospective
investors in the Notes, and securities analysts and market making financial institutions on the agreement of such Persons to (i) treat all such reports (and the information contained therein) and information as confidential, (ii) not use such
reports and the information contained therein for any purpose other than their investment or potential investment in the Notes and (iii) not publicly disclose any such reports (and the information contained therein) and information. 

(d)    The Company will also hold quarterly conference calls for the Holders of Notes, prospective investors in the Notes
and securities analysts and market making financial institutions, to discuss financial information for the previous quarter (it being understood that such quarterly conference call may be the same conference call as with the Company’s (or as
applicable, any of any Parent Entity’s) equity investors and analysts). The conference call will be following the last day of each fiscal quarter of the Company and not later than ten (10) Business Days from the time that the Company
distributes the financial information as set forth in the third preceding paragraph. No fewer than two days prior to the conference call, the Company will issue a press release announcing the time and date of such conference call and providing
instructions for Holders, securities analysts and prospective investors and market making financial institutions to obtain access to such call. 

(e)    The Company may satisfy its obligations pursuant to this Section 3.10 with respect to
financial information relating to the Company by furnishing financial information relating to a Parent Entity; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the
information relating to such Parent Entity (and other direct or indirect Parent Entities included in such information, if any), on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on
the other hand. For the avoidance of doubt, the consolidating information referred to in the proviso in the preceding sentence need not be audited.

 (f)    Notwithstanding anything to the contrary set forth in this Section
3.10, if the Company or any Parent Entity of the Company has furnished to the Holders of Notes or filed with the SEC the reports described in the preceding paragraphs with respect to the Company or any Parent Entity, the Company shall be deemed
to be in compliance with the provisions of this Section 3.10. 
 (g)    Delivery of reports, information and
documents by the Company or Subsidiary Guarantors to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The Trustee shall have no liability or
responsibility for the timeliness, filing or content of any such report. 
 SECTION 3.11.    [Reserved]. 

SECTION 3.12.    Maintenance of Office or Agency. 

The Company will maintain an office or agency where the Notes may be presented or surrendered for payment, where, if applicable, the Notes may
be surrendered for registration of transfer or exchange. The corporate trust office of the Trustee, which initially shall be located at Wells Fargo Bank, National Association, 150 East 42nd Street, 40th Floor, New York, New York 10017,
Attention: Corporate Trust Services—Administrator for Versum Materials, Inc., shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The
Company 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 Company 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 or served at the corporate trust office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations and surrenders. 

The Company 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 Company 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. The office of the Trustee shall not be an office or agency of the Company for the purposes of service of legal process on the Company or any Guarantor. 

SECTION 3.13.    Corporate Existence. Subject to, and as permitted under, Article IV, and the ability
of the Company or any of its Subsidiaries to convert (or similar action) to another form of legal entity under the laws of the jurisdiction under which the Company or such Subsidiary then exists, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect its limited liability company existence, and the corporate, partnership or other similar existence of each of its Subsidiaries, in accordance with the respective organizational documents (as
the same may be amended from time to time) of the Company or any such Subsidiary; provided, however, that the Company shall not be required to preserve or keep the corporate, partnership or other existence of any of its Subsidiaries, if the Company
shall determine that the preservation or keeping thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole. 

SECTION 3.14.    Payment of Taxes. The Company will pay, and will cause each of its Restricted Subsidiaries to
pay, prior to delinquency, all of its and their, as applicable, taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders of the Notes. 
 SECTION 3.15.    [Reserved]. 

SECTION 3.16.    Compliance Certificate. The Company shall deliver to the Trustee within 120 days after
the end of each fiscal year of the Company an Officer’s Certificate, the signer of which shall be the principal 

  
 -85- 








 
executive officer, principal financial officer or principal accounting officer of the Company, stating that in the course of the performance by the signer of his or her duties as an Officer of
the Company 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 or subsequent period 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 Company is
taking or proposes to take with respect thereto. 
 SECTION 3.17.    Further Instruments and Acts. Upon
request of the Trustee or as necessary to comply with future developments or requirements, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively
the purpose of this Indenture. 
 SECTION 3.18.    [Reserved]. 

SECTION 3.19.    Statement by Officers as to Default. The Company shall deliver to the Trustee, as soon as
reasonably practical and in any event within 5 days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status
and the actions which the Company is taking or proposes to take with respect thereto, but only to the extent such Default or Event of Default has not been cured by the end of such 5 day period. 

SECTION 3.20.    Designation of Restricted and Unrestricted Subsidiaries. The Company may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned
by the Company and its Restricted Subsidiaries in the Subsidiary 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 as
described in Section 3.3 or under one or more clauses of the definition of Permitted Investment, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by 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 this Indenture and any Indebtedness of such Subsidiary will be deemed to be Incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be
Incurred as of such date by Section 3.2, the Company will be in default of such covenant. 
 The Company may at any time designate
any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary 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 (including pursuant to clause (b)(6)(y) thereof treating such redesignation as an acquisition for the purpose of such clause), 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 Company shall be
evidenced to the Trustee by an Officer’s Certificate certifying that such designation complies with the preceding conditions. 

SECTION 3.21.    Suspension of Certain Covenants on Achievement of Investment Grade Status. Following the
first day the Notes have achieved Investment Grade Status and no Default or Event of Default has occurred and is continuing under this Indenture, the beginning on that day and ending on a Reversion Date (such period a “Suspension
Period”), the Company 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). 

  
 -86- 








 On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be deemed to
have been outstanding on the Issue Date, so that it is classified as permitted under Section 3.2(b)(5)(ii). On and after the Reversion Date, all Liens created during the Suspension Period will be considered Permitted
Liens. 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 prior to, but not during, the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under
Section 3.3(a). On the Reversion Date, the amount of Excess Proceeds shall be reset at zero. Any Affiliate Transaction entered into after the Reversion Date pursuant to an agreement entered into during any
Suspension Period will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 3.8(b)(6). Any encumbrance or restriction on the ability of any Non-Guarantor Subsidiaries to take any
action described in Section 3.4(a)(1) through (3) that becomes effective during the Suspension Period will be deemed to have existed on the Issue Date, so that it is classified as permitted under Section 3.4(b)(1). In
addition, any future obligation to grant further Guarantees shall be released. All such further obligations to grant Guarantees shall be reinstated on the Reversion Date.

Notwithstanding anything herein to the contrary, 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 the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period or any
actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period.

 On or after each Reversion Date, the Company and its Subsidiaries will be permitted to consummate the transactions contemplated by any
contract entered into during the Suspension Period, so long as such contract and such consummation would have been permitted during the Suspension Period. 

The Company, in an Officer’s Certificate, shall provide the Trustee notice of any Covenant Suspension or Reversion Date. Any failure
of the Company to deliver such Officer’s Certificate or, or any defect therein, shall not, however, in any way impair or affect the validity of any events described under this Section 3.21. The Trustee will have no obligation to
(i) independently determine or verify if such events have occurred or (ii) make any determination regarding the impact of actions taken during the Suspension Period on the Company’s future compliance with its covenants. In
addition, the Trustee shall have no duty to monitor the ratings of the Notes, shall not be deemed to have any knowledge of the ratings of the Notes and shall have no duty to notify Holders if the Notes achieve Investment Grade Status.

Default or Event of Default shall have occurred and be continuing;

purposes of effecting the Spin-Off shall not be subject to this Section 4.1. 
 (f)    The foregoing provisions
(other than the requirements of clause (a)(2) of this Section 4.1) shall not apply to the creation of a new Subsidiary as a Restricted Subsidiary or to the transfer of assets among the Company and its Subsidiaries.

provisions of Section 5.7 hereof, it must furnish to the Trustee, at least 15 days but not more than 60 days before a redemption date, an Officer’s Certificate setting forth: 

(1)    the clause of this Indenture pursuant to which the redemption shall occur; 

(2)    the redemption date; 

(3)    the principal amount of Notes to be redeemed; 

(4)    the redemption price; and 

(5)    CUSIPs/ISINs. 

Any optional redemption referenced in such Officer’s Certificate may be cancelled by the Company at any time prior to notice of
redemption being sent to any Holder and thereafter shall be null and void. 
 SECTION 5.2.    Selection of Notes to
Be Redeemed or Purchased. If less than all of the Notes are to be redeemed pursuant to Section 5.7 or purchased in an Asset Disposition Offer pursuant to Section 3.5 the Trustee will
select Notes for redemption or purchase (a) if the Notes are in global form, on a pro rata basis or such similar method in accordance with the applicable procedures of DTC and (b) if the Notes are in definitive form, on a pro rata basis
(subject to adjustments to maintain the authorized Notes denomination requirements) except: 
 (1)    if
the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or 

(2)    if otherwise required by law. 

No Notes in an unauthorized denomination or of less than $2,000 in aggregate principal amount shall be redeemed in part. In the event of
partial redemption, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 15 days nor more than 60 days prior to the redemption or purchase date by the Trustee from the
outstanding Notes not previously called for redemption or purchase; provided that the Company shall provide the Trustee with sufficient notice of such partial redemption to enable the Trustee to select the Notes for partial redemption. 

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected
for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes
called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

 SECTION 5.3.    Notice of Redemption. At least 15 days but
not more than 60 days before a redemption date, the Company will send or cause to be sent, by electronic delivery or by first class mail postage prepaid, a notice of redemption to each Holder (with a copy to the Trustee) whose Notes are to be
redeemed at the address of such Holder appearing in the Notes Register or otherwise in accordance with the procedures of DTC, except that redemption notices may be sent 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 Articles VIII or XI hereof. 

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

(1)    the redemption date; 

(2)    the redemption price; 

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

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

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

Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 

(8)    that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed
in such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the notice of redemption in the
Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 5 days prior to the redemption date (or such shorter period as the Trustee may agree), an Officer’s Certificate
requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

Notice of any redemption of the Notes may, at the Company’s discretion, be given prior to the completion of a corporate transaction
(including, but not limited to, an Equity Offering, an incurrence of Indebtedness, a Change of Control or other corporate transaction) and any redemption notice may, at the Company’s discretion, be subject to one or more conditions precedent,
including, but not limited to, completion of a related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent such notice shall describe each such condition, and if applicable, shall state
that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all
such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s
obligations with respect to such redemption may be performed by another Person. 
 SECTION 5.4.    [Reserved] 

  
 -90- 








 SECTION 5.5.    Deposit of Redemption or Purchase Price. Prior to
11:00 a.m. New York City Time on the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on, all Notes to be redeemed
or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price
of, and accrued interest, on, all Notes to be redeemed or purchased. 
 If the Company 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 up to the redemption date shall be paid on the redemption date to the Person in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company 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 hereof. 

SECTION 5.6.    Notes Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased in
part, the Company will issue and, upon receipt of a Company Order, the Trustee will authenticate for the Holder at the expense of the Company 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 minimum principal amount of $2,000 or integral multiple of $1,000 in excess thereof. 

SECTION 5.7.    Optional Redemption. 

(a)    At any time prior to September 30, 2021, the Company may redeem the Notes in whole or in part, at its option, upon
not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Notes Register, at a redemption price (expressed as percentages of principal amount of
the Notes to be redeemed) equal to 100.000% of the principal amount of Notes redeemed plus the relevant Applicable Premium as of, and accrued and unpaid interest, if any, to but excluding the date of redemption (the
“Redemption Date”), subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date. 

(b)    At any time and from time to time prior to September 30, 2019, the Company may, on one or more occasions, upon not
less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Notes Register, redeem up to 40.0% of the original aggregate principal amount of Notes
issued under this Indenture at a redemption price (expressed as percentages of principal amount of the Notes to be redeemed) equal to 105.500% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to but excluding the
applicable Redemption Date, subject to the right of Holders of record of the Notes on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds received from one or more Equity Offerings;
provided that not less than 50.0% of the original aggregate principal amount of Notes initially issued under this Indenture remains outstanding immediately after the occurrence of each such redemption (excluding Notes held by the Company or
any of its Restricted Subsidiaries); provided further that each such redemption occurs not later than 180 days after the date of closing of the related Equity Offering. The Trustee shall select the Notes to be purchased in the
manner described under Sections 5.1 through 5.6. 
 (c)    Except pursuant to
clauses (a) and (b) of this Section 5.7, the Notes will not be redeemable at the Company’s option prior to September 30, 2021. 

(d)    At any time and from time to time on or after September 30, 2021, the Company may redeem the Notes, in whole or in
part, upon not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Notes Register at the redemption prices (expressed as percentages of
principal amount of the Notes to be redeemed) set forth in the table below, plus accrued and unpaid interest thereon, if any, to but excluding the applicable Redemption Date, subject to the right of Holders of record of the Notes on the
relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on September 30 of each of the years indicated in the table below:

	 2022
	  	 	101.375	% 
	 2023 and thereafter
	  	 	100.000	% 

 (e)    Notwithstanding the foregoing, in connection with any Change of Control Offer or
Asset Disposition Offer, if Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such offer and the Company, or any third party making such tender offer in lieu of the
Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party shall have the right upon not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each
Holder of Notes to the address of such Holder appearing in the Notes Register, given not more than 15 days following such purchase date have elapsed to redeem all Notes that remain outstanding following such purchase at a redemption price equal to

portions thereof called for redemption on the applicable Redemption Date. 
 (g)    Any redemption pursuant to this
Section 5.7 shall be made pursuant to the provisions of Sections 5.1 through 5.6. 

SECTION 5.8.    Mandatory Redemption. The Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes; provided however, that under certain circumstances, the Company may be required to offer to purchase Notes under Section 3.5 and Section 3.9. The Company may at any time and from time to
time purchase Notes in the open market or otherwise. 
 ARTICLE VI 

DEFAULTS AND REMEDIES 

SECTION 6.1.    Events of Default. 

(a)    Each of the following is an “Event of Default”: 

(1)    default in any payment of interest on any Note when due and payable, continued for 30 days;

 (2)    default in the payment of the principal amount of or premium, if any, on any Note issued under
this Indenture when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; 

(3)    failure by the Company or any Guarantor to comply for 60 days after written notice by the
Trustee on behalf of the Holders or by the Holders of 30.0% in principal amount of the outstanding Notes with any agreement or obligation contained in this Indenture; provided that in the case of a failure to comply with this Indenture
provisions described under Section 3.10, such period of continuance of such default or breach shall be 270 days after written notice described in this clause (3) has been given; 

(4)    default under any mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the Company or any Significant Subsidiary (or the payment of which is Guaranteed by the Company or any Significant Subsidiary) other than Indebtedness owed to the Company or a
Restricted Subsidiary whether such Indebtedness or Guarantee now exists, or is created after the date hereof, which default: 

  
 -92- 








 (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) (“payment default”); or 

(B)    results in the acceleration of such Indebtedness prior to its stated final maturity; 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which
there has been a payment default of principal at its stated final maturity (after giving effect to any applicable grace periods) or the maturity of which has been so accelerated, aggregates to $50.0 million or more at any one time outstanding;

 (5)    failure by the Company or any Significant Subsidiary (or group of Restricted Subsidiaries that,
taken together (as of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary), to pay final judgments aggregating in excess of $100.0 million other than
any judgments covered by indemnities provided by, or insurance policies issued by, reputable and creditworthy companies, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment
becomes final and unappealable, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; 

(6)    any Note Guarantee by a Significant Subsidiary ceases to be in full force and effect, other than
(x) in accordance with the terms of this Indenture, (y) a Guarantor that is a Significant Subsidiary denies or disaffirms its obligations under its Note Guarantee, other than in accordance with the terms of this Indenture or upon release
of such Note Guarantee in accordance with this Indenture or (z) in connection with the bankruptcy of a Guarantor, so long as the aggregate assets of such Guarantor and any other Guarantor whose Note Guarantee ceased or ceases to be in full
force as a result of a bankruptcy are less than $50.0 million; 
 (7)    the Company or any Guarantor
that is Significant Subsidiary or any group of Guarantors that, taken together (as of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary pursuant to or
within the meaning of any Bankruptcy Law: 
 (A)    commences a voluntary case or proceeding; 

(B)    consents to the entry of an order for relief against it in an involuntary case or proceeding; 

(C)    consents to the appointment of a Custodian of it or for substantially all of its property; 

(D)    makes a general assignment for the benefit of its creditors; 

(E)    consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against
it; or 
 (F)    takes any comparable action under any foreign laws relating to insolvency; 

  
 -93- 








 (8)    a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that: 
 (A)    is for relief against the Company or any Guarantor that
is a Significant Subsidiary or any group of Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary, in an involuntary case; 

(B)    appoints a Custodian of the Company, any Guarantor that is a Significant Subsidiary or any group of
Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary, for substantially all of its property; 

(C)    orders the winding up or liquidation of the Company, any Guarantor that is a Significant Subsidiary
or any group of Guarantors that, taken together as of the latest audited consolidated financial statements for the Company, would constitute a Significant Subsidiary; or 

(D)    or any similar relief is granted under any foreign laws and the order, decree or relief remains
unstayed and in effect for 60 consecutive days; 
 provided that a Default under clause (3), (4) or (5) above will not constitute an Event of Default until
the Trustee or the Holders of 30.0% in principal amount of the outstanding Notes notify the Company of the Default and, with respect to clauses (3) and (5), the Company does not cure such Default within the time specified in clauses (3) and (5), as
applicable, after receipt of such notice. 
 (b)    If a Default for a failure to report or 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. 

(c)    Any Default or Event of Default for the failure to comply with the time periods prescribed in Section 3.10
hereof 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 such provision or such notice or certificate, as applicable, even
though such delivery is not within the prescribed period specified in this Indenture. 
 SECTION
6.2.    Acceleration. If an Event of Default (other than an Event of Default described in clauses (7) or (8) of Section 6.1(a)) occurs and is continuing, the Trustee by written notice to
the Company, or the Holders of at least 30.0% in principal amount of the outstanding Notes by written notice to the Company and the Trustee, may declare the principal of and accrued and unpaid interest, if any, 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. 
 In the event
of any Event of Default specified in clause (4) of Section 6.1(a), such Event of Default and all consequences thereof shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the
Holders, if within 30 days after such Event of Default arose: 

(1)    (x)    the Indebtedness that gave rise to such Event of Default shall have been
discharged in full; or 
          (y)    the holders
thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default; or 

         (z)    if the default that is the basis for such
Event of Default has been remedied or cured; and 

  
 -94- 








 (2)    the annulment of the acceleration of the Notes would
not conflict with any judgment or decree of a court of competent jurisdiction. 
 If an Event of Default described in clauses (7) or
(8) of Section 6.1(a) with respect to the Company occurs and is continuing, the principal of and accrued and unpaid interest, if any, 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. 
 SECTION 6.3.    Other Remedies. If an Event of
Default occurs and is continuing, the Trustee may pursue any available contractual remedy under this Indenture 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. 

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), an existing Default or Event of Default and its consequences under this Indenture except (i) a Default or Event of Default in the payment of the principal of, or interest, if any, on a Note held by a non-consenting Holder or (ii) a
Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended 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, 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 and overdue principal, which has become due otherwise than by such declaration of
acceleration, has been paid, (4) the Company has paid the Trustee its compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances (including reasonable attorney’s and agent’s fees and expenses) and
(5) 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. 
 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 pursuant
to this Indenture or at law or of exercising any trust or power conferred on the Trustee pursuant to this Indenture or at law. 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 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 satisfactory to it against all fees, losses,
liabilities 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. Subject to Section 6.7, a Holder may not 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 30.0% in principal amount of the outstanding Notes have requested in
writing the Trustee to pursue the remedy; 

  
 -95- 








 (3)    such Holders have offered in writing and, if
requested, provided to 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)    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. 

It is understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances of a Holder are
unduly prejudicial to any other Holder. 
 SECTION 6.7.    Rights of Holders to Receive
Payment. Notwithstanding any other provision of this Indenture (including, without limitation, Section 6.6), the contractual right expressly set forth in this Indenture of any Holder to receive payment of interest
on the Notes held by such Holder or to institute suit for the enforcement of any such payment on or with respect to such Holder’s Notes after the due date therefor shall not be amended without the consent of such Holder (and, for the avoidance
of doubt, the amendment, supplement or modification in accordance with the terms of this Indenture of Articles III and IV and Sections 6.1(a)(3), (4), (5) and (6) and the related definitions shall be deemed
not to impair the contractual right of any Holder to receive payments of principal of and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any such payment on or with respect to such
Holder’s Note). 
 SECTION 6.8.    Collection Suit by Trustee. If an Event of Default specified in
clauses (1) or (2) of Section 6.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together
with interest on any unpaid interest to the extent lawful) and the amounts provided for hereunder. 
 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 the Company, its Subsidiaries or its or their respective creditors or
properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any Custodian 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 hereunder. 

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 (acting in any capacity hereunder) for amounts due to it
hereunder; 
 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 

  
 -96- 








 THIRD: to the Company, or to the extent the Trustee collects any amount for
any Guarantor, to such Guarantor. 
 (b)    The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10. At least 15 days before such record date, the Company 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 as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of 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 Company, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10.0% in outstanding
principal amount of the Notes. 
 ARTICLE VII 

TRUSTEE 
 SECTION
7.1.    Duties of Trustee. 
 (a)    If an Event of Default has occurred and is continuing,
the Trustee shall exercise the contractual rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such
person’s own affairs. 
 (b)    Except during the continuance of an Event of Default: 

(1)    the Trustee undertakes to perform such duties and only such duties as are specifically set forth in
this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(2)    the Trustee may conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates, opinions or orders furnished to the Trustee and conforming to the requirements of this Indenture or the Notes, as the case may be. However, in the case of any such certificates or 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 negligent action, its own negligent failure to act or
its own willful misconduct, except that: 
 (1)    this paragraph does not limit the effect of
paragraph (b) of this Section 7.1; 
 (2)    the Trustee shall not be
liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; 

(3)    the Trustee shall not be liable with respect to any action it takes or omits to take in good faith
in accordance with a direction received by it pursuant to Section 6.5; and 

(4)    No provision of this Indenture or the Notes shall require the Trustee to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its duties hereunder or thereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. 

  
 -97- 








 (d)    Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.1. 
 (e)    The
Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. 

(f)    Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

 (g)    Every provision of this Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section 7.1. 
 SECTION
7.2.    Rights of Trustee. Subject to Section 7.1: 

(a)    The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or
presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. The Trustee shall receive and retain financial reports and statements of the Company as provided herein, but shall have no duty to
review or analyze such reports or statements to determine compliance with covenants or other obligations of the Company. 

(b)    Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate and/or an Opinion of
Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officer’s Certificate or Opinion of Counsel. 

(c)    The Trustee may execute any of the trusts and powers hereunder or perform any duties hereunder either directly or
by or through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care by it hereunder. 

(d)    The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be
authorized or within its rights or powers conferred upon it by this Indenture. 
 (e)    The Trustee may consult with
counsel of its selection, and the advice or opinion of counsel relating to this Indenture or the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder or
under the Notes in good faith and in accordance with the advice or opinion of such counsel. 
 (f)    The Trustee shall
not be deemed to have notice of any Default or Event of Default or whether any entity or group of entities constitutes a Significant Subsidiary unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event
which is in fact such a Default or of any such Significant Subsidiary is received by the Trustee at the corporate trust office of the Trustee specified in Section 3.12, and such notice references the Notes and this
Indenture. 
 (g)    The rights, privileges, protections, immunities and benefits given to the Trustee, including,
without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder. 

(h)    The Trustee shall be under no obligation to exercise any of the contractual rights or powers vested in it by this
Indenture or the Notes at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs,
expenses and liabilities which may be incurred therein or thereby. 
 (i)    The Trustee shall not be deemed to have
knowledge of any fact or matter unless such fact or matter is actually known to a Trust Officer of the Trustee. 

  
 -98- 








 (j)    Whenever in the administration of this Indenture or the Notes the
Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder or thereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of gross
negligence or willful misconduct on its part, conclusively rely upon an Officer’s Certificate. 
 (k)    The
Trustee shall not be bound to make any investigation into the facts or matters stated in any 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 the Company and the Restricted Subsidiaries, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any
kind by reason of such inquiry or investigation. 
 (l)    The Trustee shall not be required to give any bond or surety
in respect of the performance of its powers and duties hereunder. 
 (m)    The Trustee may request that the Company
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 Company
shall be sufficient if signed by one Officer of the Company. 
 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 Company, 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
Section 7.10. In addition, the Trustee shall be permitted to engage in transactions with the Company; provided, however, that if the Trustee acquires any conflicting interest, the Trustee must (i)
eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) 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 or the Notes, shall not be accountable for the Company’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 or any money paid to the Company pursuant to the terms of this Indenture and shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale
of the Notes or in the Notes other than the Trustee’s certificate of authentication. 
 SECTION 7.5.    Notice
of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof or is informed of such occurrence by the Company, the Trustee shall send electronically or by first class mail to
each Holder at the address set forth in the Notes Register notice of the Default or Event of Default within 60 days after it is actually known to a Trust Officer or being notified by the Company. Except in the case of a Default or Event of
Default in payment of principal of or interest on any Note (including payments pursuant to the optional redemption or required repurchase provisions of such Note), the Trustee may withhold the notice if and so long it in good faith determines that
withholding the notice is in the interests of Holders. 
 SECTION 7.6.    [Reserved]. 

  
 -99- 








 SECTION 7.7.    Compensation and Indemnity. The Company shall pay
to the Trustee from time to time compensation for its services hereunder and under the Notes as the Company 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 Company shall reimburse the Trustee (in any capacity hereunder) upon request for all reasonable and documented
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 of notices to Holders. Such expenses shall include the reasonable and documented compensation and expenses, disbursements and advances of the agents, counsel, accountants and experts of the Trustee. The Company
shall indemnify the Trustee (in any capacity hereunder), its directors, officers, employees and agents against any and all loss, liability, damages, claims or expense, including taxes (other than taxes based upon the income of the Trustee)
(including reasonable and documented attorneys’ and agents’ fees and expenses) incurred by it without willful misconduct or gross negligence, as determined by a final nonappealable 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 costs and expenses of enforcing this Indenture (including this Section 7.7) and the Notes and
of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify the Company 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 Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense. The
Trustee may have separate counsel and the Company shall pay the reasonable and documented fees and expenses of such counsel; provided that the Company shall not be required to pay the fees and expenses of such separate counsel if it assumes
the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the Trustee in connection with such defense. 

To secure the Company’s payment obligations hereunder, the Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes. Such lien shall survive the satisfaction and discharge of this Indenture. The Trustee’s respective right to
receive payment of any amounts due hereunder shall not be subordinate to any other liability or Indebtedness of the Company. 
 The
Company’s payment obligations hereunder shall survive the discharge of this Indenture and any resignation or removal of the Trustee under Section 7.8. 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 clause (7) or clause (8) of Section 6.1(a), the fees and expenses (including the reasonable fees and
expenses of its counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
 SECTION
7.8.    Replacement of Trustee. The Trustee may resign at any time by so notifying the Company 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 Company’s written consent,
which consent will not be unreasonably withheld. The Company shall remove the Trustee if: 

(1)    the Trustee fails to comply with Section 7.10 hereof; 

(2)    the Trustee is adjudged bankrupt or insolvent; 

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

(4)    the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed by the Company 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 Company
shall promptly appoint a successor Trustee. 

  
 -100- 








 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee
and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee
shall mail a notice of its succession to Holders. The retiring Trustee shall, at the expense of the Company, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.7. 
 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 10.0% in principal amount of the Notes may petition, at the Company’s expense, any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, any Holder, who has been a bona fide holder of a Note for at least
six months, may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under
Section 7.7 shall continue for the benefit of the retiring Trustee. The predecessor Trustee shall have no responsibility or 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. This Indenture shall always have a Trustee. The Trustee
shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. 

SECTION 7.11.    [Reserved]. 

SECTION 7.12.    Trustee’s Application for Instruction from the Company. Any application by the Trustee
for written instructions from the Company 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 Business Days after the date any Officer of the Company 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 Company may, at its
option and at any time, elect to have either Section 8.2 or 8.3 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII. 

  
 -101- 








 SECTION 8.2.    Legal Defeasance and Discharge. Upon the
Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth
in Section 8.4 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Guarantees) on the date the conditions set forth below are satisfied (hereinafter,
“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the
Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof 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 the Note Documents (and the Trustee, on written demand of and at the expense of the Company, shall execute such instruments reasonably requested by the Company 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 hereof; 

(2)    the Company’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 3.12 hereof concerning the maintenance of an office or agency for payment and money for security payments held in trust;

 (3)    the rights, powers, trusts, duties and immunities of the Trustee and the Company’s or
Guarantors’ obligations in connection therewith; and 
 (4)    this
Article VIII with respect to provisions relating to Legal Defeasance. 
 SECTION
8.3.    Covenant Defeasance. Upon the Company’ exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Company and each of the
Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, 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, 3.16, 3.19, 3.20, 3.21 and Section 4.1 (except Section 4.1(a)(1) and
(a)(2)) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.4 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will
thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of 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 Guarantees, the Company 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) hereof, but, except as specified above, the remainder of this Indenture and
such Notes and Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the
satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(a)(3) (other than with respect to Section 4.1(a)(1) and (a)(2)), 6.1(a)(4),
6.1(a)(5), 6.1(a)(6), 6.1(a)(7) (with respect only to a Guarantor that is a Significant Subsidiary or any group of Guarantors that taken together would constitute a Significant Subsidiary), and 6.1(a)(8) (with respect
only to a Guarantor that is a Significant Subsidiaries or any group of Guarantors that taken together would constitute a Significant Subsidiary) hereof shall not constitute Events of Default. 

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 hereof: 

(1)    the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders,
cash in Dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of and premium, if any, and
interest, due on the Notes issued under this Indenture on the stated maturity date or on the applicable redemption date, as the case may be, and the Company must specify whether such Notes are being defeased to maturity or to a particular redemption
date; 

  
 -102- 








 (2)    in the case of Legal Defeasance, the Company shall
have delivered to the Trustee an Opinion of Counsel in the United States confirming that, subject to customary assumptions and exclusions; 

(A)    the Company has received from, or there has been published by, the United States Internal Revenue
Service a ruling; or 
 (B)    since the issuance of such Notes, there has been a change in the
applicable U.S. federal income tax law; 
 in either case to the effect that, and based thereon such Opinion of Counsel in the United
States shall confirm that, subject to customary assumptions and exclusions, the Holders, in their capacity as Holders of the Notes; 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 in the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3)    in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of
Counsel in the United States confirming that, subject to customary assumptions and exclusions, the Holders, in their capacity as Holders of the Notes, will not recognize income, gain or loss for U.S. federal income tax purposes as a result of
such Covenant Defeasance and will be subject to 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 the Credit Facilities or any other material agreement or instrument (other than this Indenture) to which, the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 

(6)    [reserved]; 

(7)    the Company shall have delivered to the Trustee an Officer’s Certificate stating that the
deposit was not made by the Company with the intent of defeating, hindering, delaying, defrauding or preferring any creditors of the Company or any Guarantor or others; and 

(8)    the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may
be, have been complied with. 
 SECTION 8.5.    Deposited Money and U.S. Government Obligations to be Held in Trust;
Other Miscellaneous Provisions. Subject to Section 8.6 hereof, 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 hereof 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 Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal, premium, and interest, but such money need not be segregated from other funds except to the extent required by law. 

  
 -103- 








 The Company 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 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article VIII to the
contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or U.S. Government Obligations held by it as provided in Section 8.4 hereof which, in the opinion of
a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(1) hereof), are in excess of the
amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 SECTION
8.6.    Repayment to the Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium or interest on, any Note and remaining
unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on their written request unless an abandoned property law designates another Person or (if then held by the Company) will be
discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof 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 Company as trustee thereof, will thereupon cease. 
 SECTION
8.7.    Reinstatement. If the Trustee or Paying Agent is unable to apply any money or Dollars or U.S. Government Obligations in accordance with Section 8.2 or 8.3 hereof, as the case
may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and
the Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance
with Section 8.2 or 8.3 hereof, as the case may be; provided, however, that, if the Company make any payment of principal of, premium, or interest on, any Note following the reinstatement of its
obligations, the Company 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 of this
Indenture, the Company, any Guarantor (with respect to its Guarantee or this Indenture), if applicable, and the Trustee may amend, supplement or modify this Indenture, any Guarantee and the Notes without the consent of any Holder: 

(1)    to cure any ambiguity, omission, mistake, defect, error or inconsistency, conform any provision to
any provision under the heading “Description of Notes” (as provided for in an Officer’s Certificate) in the Offering Memorandum or reduce the minimum denomination of the Notes; 

(2)    to provide for the assumption by a successor Person of the obligations of the Company or a Guarantor
under any Note Document; 
 (3)    to provide for uncertificated Notes in addition to or in place of
certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code); 

(4)    to add to the covenants or provide for a Note Guarantee for the benefit of the Holders or to
surrender any right or power conferred upon the Company or any Restricted Subsidiary; 
 (5)    to add
additional events of default; 

  
 -104- 








 (6)    to make any change that does not adversely affect the
rights of any holder of any series of debt securities, including the Notes, in any material respect; 

(7)    to change or eliminate any provisions of this Indenture so long as there are no Holders entitled to
the benefit of the provisions; 
 (8)    at the Company’s election, to comply with any requirement
of the SEC in connection with the qualification of this Indenture under the TIA, if such qualification is required; 

(9)    to make such provisions as necessary (as determined in good faith by the Company) for the issuance
of Additional Notes; 
 (10)    to provide for any Restricted Subsidiary to provide a Note Guarantee in
accordance with Section 3.2, to add Guarantees with respect to the Notes, to add security to or for the benefit of the Notes, or to confirm and evidence the release, termination, discharge or retaking of any Guarantee or
Lien with respect to or securing the Notes when such release, termination, discharge or retaking is provided for under this Indenture; 

(11)    to evidence and provide for the acceptance and appointment under this Indenture of a successor
Trustee pursuant to the requirements hereof or to provide for the accession by the Trustee to any Note Document; 

(12)    to supplement any of the provisions of this Indenture to such extent as shall be necessary to
permit or facilitate the defeasance and discharge of any series of Notes so long as any such action shall not adversely affect the interests of any Holder of such series of Notes or any other series of debt securities issued thereunder; 

(13)    to prohibit the authentication and delivery of additional series of Notes; 

(14)    to comply with the merger and consolidation provisions pursuant to this Indenture; 

(15)    in the case of subordinated debt securities, to make any change to the provisions of this Indenture
or any supplemental indenture relating to subordination that would limit or terminate the benefits available to any holder of senior Indebtedness under such provisions (but only if each such holder of senior Indebtedness under such provisions
consents to such change); or 
 (16)    to make any amendment to the provisions of this Indenture
relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of Notes; provided, however, that (i) compliance with this Indenture as
so amended would not result in Notes being transferred in violation of the Securities Act or any other 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 Company and upon receipt by the Trustee of the documents
described in Section 9.6 hereof, the Trustee will join with the Company and the Guarantors, if applicable, in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the
Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 

After an amendment or supplement under this Section 9.1 becomes effective, the Company shall provide to Holders a
notice briefly describing such amendment or supplement, which the Company may do by making such notice publicly available by filing with the SEC. The failure to provide 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. 

  
 -105- 








 SECTION 9.2.    With Consent of Holders. Except as provided below
in this Section 9.2, the Company, the Guarantors, if applicable, and the Trustee may amend or supplement this Indenture, any Guarantee and the Notes issued hereunder with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes then outstanding and issued under this Indenture, including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes, and, subject to
Sections 6.4 and 6.7 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default
resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes and the Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then
outstanding Notes issued under this Indenture (including consents obtained in connection with a purchase of or tender offer or exchange offer for Notes). Section 2.12 hereof and Section 12.4
hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.2. 

Upon the request of the Company and upon the filing with the Trustee of evidence of the consent of the Holders of Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee will join with the Company and the Guarantors, if applicable, in the execution of such amended or supplemental indenture unless such
amended or supplemental indenture affects the Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or
supplemental Indenture. 
 Without the consent of each Holder of Notes affected, an amendment, supplement or waiver may not, with respect to
any Notes issued thereunder and held by a nonconsenting Holder: 
 (1)    reduce the principal amount of
such Notes whose Holders must consent to an amendment; 
 (2)    reduce the stated rate of or extend the
stated time for payment of interest on any such Note (other than provisions relating to Section 3.5 and Section 3.9); 

(3)    reduce the principal of or extend the Stated Maturity of any such Note (other than provisions
relating to Section 3.5 and Section 3.9); 

(4)    reduce the premium payable upon the redemption of any such Note or change the time at which any such
Note may be redeemed, in each case as set forth in Section 5.7; 
 (5)    make
any such Note payable in currency other than that stated in such Note; 
 (6)    make any change to the
contractual right of any Holder to receive payment of and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any such payment on or with respect to such Holder’s Notes (and, for
the avoidance of doubt, the amendment, supplement or modification in accordance with the terms of this Indenture of Articles III and IV and Sections 6.1(a)(3), (4), (5) and (6) and the related definitions
shall be deemed not to impair the contractual right of any Holder to receive payment of principal of and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any such payment on or with
respect to such Holder’s Note); 
 (7)    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 such Notes and a waiver of the payment default that resulted from such
acceleration); or 
 (8)    make any change in the amendment or waiver provisions which require the
Holders’ consent described in this Section 9.2. 

  
 -106- 








 It shall not be necessary for the consent of the Holders under this Indenture to approve the
particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment, supplement or waiver under this Indenture by any Holder of the Notes given
in connection with a tender or exchange of such Holder’s Notes will not be rendered invalid by such tender or exchange. 
 After an
amendment or supplement under this Section 9.2 becomes effective, the Company shall provide to Holders a notice briefly describing such amendment or supplement, which the Company may do by making such notice publicly
available by filing with the SEC. The failure to provide such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement. 

SECTION 9.3.    Compliance with this Indenture. Every amendment or supplement to this Indenture, any Guarantee
and the Notes will be set forth in an amended or supplemental indenture that complies with this Indenture as then in effect. 
 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 or waiver is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent or waiver 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 Company 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 above 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 Company in exchange for all Notes may issue and the Trustee shall, upon receipt of a Company Order, authenticate new Notes that reflect the amendment, supplement or
waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment,
supplement or waiver. 
 SECTION 9.6.    Trustee to Sign Amendments. The Trustee shall sign any amended or
supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the
Trustee shall receive and (subject to Sections 7.1 and 7.2 hereof) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 12.2 hereof, an
Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and is valid, binding and enforceable against the Company and the Guarantors party
thereto, if any, in accordance with its terms. Notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel shall be required solely in connection with the addition of a Guarantor under this Indenture upon execution and
delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit B, and delivery of an Officer’s Certificate. 

  
 -107- 








 ARTICLE X 

GUARANTEE 
 SECTION
10.1.    Guarantee. Subject to the provisions of this Article X, each Guarantor hereby fully, unconditionally and irrevocably guarantees (the “Note Guarantees”), as primary
obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes, 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 on the Notes and all other obligations and liabilities of the Company under this Indenture (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 Company 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 Guarantees will rank senior in right of payment to such other Indebtedness. 
 To evidence its Guarantee set forth in this
Section 10.1, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer of such Guarantor. 

Each Guarantor hereby agrees that its 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 this
Indenture no longer holds that office at the time the Trustee authenticates the Note, the 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 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 any Holder to assert any claim or demand or to enforce any right or remedy against the Company 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 any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of the Company; (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. 

  
 -108- 








 Each Guarantor agrees that its 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 Guarantee in compliance with Section 10.2, Article VIII or Article XI. Each
Guarantor further agrees that its 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, interest on any of the Guaranteed Obligations is
rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company 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 Company 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 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 Company 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 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 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 Guarantee or pursuant to its contribution obligations under this Indenture, result in the
obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, foreign, state or provincial law and not otherwise being void or voidable under any similar laws affecting the rights of
creditors generally. 
 (b)    Any Note Guarantee of a Guarantor shall be automatically and unconditionally released and
discharged upon: 
 (1)    a sale or other disposition (including by way of consolidation, merger or
amalgamation) of all of the Capital Stock of such Guarantor or the sale or disposition of all or substantially all of the assets of the Guarantor to a Person other than to the Company or a Restricted Subsidiary and as otherwise permitted by this
Indenture; 
 (2)    the designation in accordance with this Indenture of the Guarantor as an
Unrestricted Subsidiary or the occurrence of any event after which the Guarantor is no longer a Restricted Subsidiary; 

(3)    defeasance or discharge of the Notes pursuant to Article VIII or
Article XI; 
 (4)    to the extent such Guarantor is not an Immaterial
Subsidiary solely due to the operation of clause (i) of the definition of “Immaterial Subsidiary,” upon the release of the guarantee referred to in such clause; 

  
 -109- 








 (5)    such Guarantor being released from all of (i) its
obligations under all of its Guarantees of payment by the Company of any Indebtedness of the Company under the Credit Agreement or (ii) in the case of a Note Guarantee made by a Guarantor (each, an “Other Guarantee”) as a result of
its guarantee of other Indebtedness of the Company or a Guarantor pursuant to Section 3.7 hereof, the relevant Indebtedness, except in the case of (i) or (ii), a release as a result of the payment under such Guarantee (it being understood
that a release subject to a contingent reinstatement is still considered a release, and if any such Guarantee of such Guarantor under the Credit Agreement or any Other Guarantee is so reinstated, such Note Guarantee shall also be reinstated); or

 (6)    upon the achievement of Investment Grade Status by the Notes; provided that such Note
Guarantee shall be reinstated upon the Reversion Date; 
 (7)    the merger or consolidation of any
Guarantor with and into the Company or upon the liquidation of such Guarantor following the transfer of all its assets to the Company; or 

(8)    the consent of Holders of a majority in aggregate principal amount of the outstanding Notes. 

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 Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Company 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 Company 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 reimbursement from the Company 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 Company 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 will cease to be of further
effect as to all Notes issued hereunder, when: 
 (a)    either: 

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

(2)    all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due
and payable by reason of the making of a notice of redemption or otherwise or (ii) will become due and payable within one year at their Stated Maturity 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 Company; 

  
 -110- 








 (b)    the Company has irrevocably deposited or caused to be deposited with
the Trustee as trust funds in trust solely for the benefit of the Holders, cash in Dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to
pay and discharge the entire Indebtedness on such 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)    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) with respect to this Indenture or the Notes issued hereunder shall have occurred and be continuing on the date of such deposit or
shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under the Credit Facilities or any other material agreement or instrument (other than this Indenture) to which the Company
or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (d)    the Company or any Guarantor
has paid or caused to be paid all sums payable by the Company under this Indenture; and 
 (e)    the Company has
delivered irrevocable instructions to the Trustee to apply the deposited money in Dollars toward the payment of such Notes issued hereunder at maturity or the redemption date, as the case may be. 

In addition, the Company shall deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions
precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, the
Company’s obligation to the Trustee in Section 7.7 hereof and, if money in Dollars has been deposited with the Trustee pursuant to clause (a)(2) of this Section 11.1, the provisions of
Sections 11.2 and 8.6 hereof will survive. 
 SECTION 11.2.    Application of Trust
Money. Subject to the provisions of Section 8.6 hereof, all money in Dollars or U.S. Government Obligations deposited with the Trustee pursuant to Section 11.1 hereof shall be held in
trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal (and premium) and interest for whose payment such money in Dollars or U.S. Government Obligations has been deposited with the Trustee; but such money in Dollars or U.S. Government Obligations 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 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company’s and any 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 hereof; provided
that if the Company has made any payment of principal of, premium or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from
the money or U.S. Government Obligations held by the Trustee or Paying Agent.

Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, any Guarantor or any Affiliate 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; provided, however, that
for so long as Air Products holds the entire aggregate principal amount of the Notes, Air Products shall be considered the sole Holder of the Notes hereunder. Also, subject to the foregoing, only Notes outstanding at the time shall be
considered in any such determination.
 SECTION 12.5.    Rules by Trustee, Paying Agent and Registrar. The
Trustee may make reasonable rules for action by, or at meetings of, Holders. The Registrar and the Paying Agent may make reasonable rules for their functions. 

SECTION 12.6.    Legal Holidays. A “Legal Holiday” is a Saturday, a Sunday or other day on
which commercial banking institutions are authorized or required to be closed in New York, New York or the state of the place of payment. If a payment date or a redemption 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. 

SECTION 12.7.    Governing Law. THIS INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 SECTION 12.8.    Jurisdiction. The
Company and the Guarantors agree that any suit, action or proceeding against the Company or any Guarantor brought by any Holder or the Trustee arising out of or based upon this Indenture, the Guarantee or the Notes may be instituted in any state or
Federal court in the Borough of Manhattan, New York, New York, and any appellate court from any thereof, and each of them irrevocably submits to the non-exclusive jurisdiction of such courts in any suit,
action or proceeding. The Company and the Guarantors 

  
 -113- 








 
irrevocably waive, to the fullest extent permitted by law, any objection to any suit, action, or proceeding that may be brought in connection with this Indenture, the Guarantee or the Notes,
including such actions, suits or proceedings relating to securities laws of the United States of America or any state thereof, in such courts whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or
proceeding has been brought in an inconvenient forum. The Company and the Guarantors agree that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Company or the Guarantors, as
the case may be, and may be enforced in any court to the jurisdiction of which the Company or the Guarantors, as the case may be, are subject by a suit upon such judgment. 

SECTION 12.9.    Waivers of Jury Trial. EACH OF THE COMPANY, THE GUARANTORS AND THE TRUSTEE HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE GUARANTEES AND FOR ANY
COUNTERCLAIM THEREIN. 
 SECTION 12.10.    USA PATRIOT Act. The parties hereto acknowledge that in
accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies
each person or legal entity that establishes a relationship or opens an account. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order to satisfy the requirements of the USA
PATRIOT Act. 
 SECTION 12.11.    No Recourse Against Others. No director, officer, employee, incorporator
or shareholder of the Company or any of its respective Subsidiaries or Affiliates as such (other than the Company and the Guarantors), shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or
this Indenture 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. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 

SECTION 12.12.    Successors. All agreements of the Company and each Guarantor in this Indenture and the Notes
shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successors. 
 SECTION
12.13.    Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies
of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all
purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 

SECTION 12.14.    Table of Contents; Headings. The table of contents,
cross-reference table and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or
restrict any of the terms or provisions hereof. 
 SECTION 12.15.    Force Majeure. In no event shall the
Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages,
accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, it being
understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

SECTION 12.16.    Severability. In case any provision in this Indenture or in the Notes shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

VERSUM MATERIALS, INC. 5.500% SENIOR NOTES DUE 2024 

Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. 

1.    Interest 
 The
Company promises to pay interest on the principal amount of this Note at 5.500% per annum from                 until maturity.The Company will pay interest semi-annually
in arrears every March 15 and September 15 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 the date of issuance; provided, that the first Interest Payment Date shall be March 15, 2017. The Company shall pay interest on overdue principal at
the rate specified herein, and it 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. 

2.    Method of Payment 

By no later than 11:00 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 Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium, 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 March 1 and September 1 at the office or agency of the Company
maintained for such purpose pursuant to Section 2.3 of the Indenture. The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent or Registrar designated by
the Company 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 Company 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

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 in accordance with the Notes Register, or
by wire transfer to a 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 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.

Agent for the Notes. The Company may change any Registrar or Paying Agent without prior notice to the Holders. The Company or any Guarantor may act as Paying Agent, Registrar or transfer agent.

Company issued the Notes under an Indenture dated as of September 30, 2016 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the guarantors named
therein 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. In
the event of a conflict between the terms of the Notes and the terms of the Indenture, the terms of the Indenture shall control.

that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 5.500% Senior Notes due 2024 referred to in the Indenture. The Notes include (i) $425,000,000 principal amount of the Company’s
5.500% Senior Notes due 2024 issued under the Indenture on September 30, 2016 (the “Initial Notes”) and (ii) if and when issued, additional Notes that may be issued from time to time under the Indenture subsequent to September
30, 2016 (the “Additional Notes”) as provided in Section 2.1(a) of the Indenture. The Initial Notes and the Additional Notes shall be considered collectively as a single class for all purposes of the
Indenture; provided that the Additional Notes will not be issued with the same CUSIP as the existing Notes unless such Additional Notes are fungible with the existing Notes for U.S. federal income tax purposes. The Indenture imposes
certain limitations on the incurrence of indebtedness, the making of restricted payments, the sale of assets, the incurrence of certain liens, the making of payments for consents, the entering into of agreements that restrict distribution from

less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Notes Register, redeem up to 40.0% of the original aggregate principal amount of Notes
issued under this Indenture at a redemption price (expressed as percentages of principal amount of the Notes to be redeemed) equal to 105.500% of the aggregate principal amount thereof, plus accrued and unpaid interest, thereon, if any, to but
excluding the applicable Redemption Date, subject to the right of Holders of record of the Notes on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds received from one or more
Equity Offerings; provided that not less than 50% of the original aggregate principal amount of Notes initially issued under the Indenture remains outstanding immediately after the occurrence of each such redemption (excluding Notes held by
the Company or any of its Restricted Subsidiaries); provided further that each such redemption occurs not later than 180 days after the date of closing of the related Equity Offering. The Trustee shall select the Notes to be
purchased in the manner described under Sections 5.1 through 5.6 of the Indenture.

 A-5 








 (d)    At any time and from time to time on or after September 30, 2021, the
Company may redeem the Notes, in whole or in part, upon not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Notes Register at the
redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth in the table below, plus accrued and unpaid interest thereon, to but excluding the applicable Redemption Date, subject to the right of
Holders of record of the Notes on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on September 30 of each of

Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party shall have the right upon not less than 15 nor more than 60 days’ prior notice, with a copy to the Trustee, to each Holder

 8.    [Reserved]. 

9.    Repurchase Provisions 

If a Change of Control occurs, unless the Company has previously or substantially concurrently therewith delivered a redemption notice with
respect to all the outstanding Notes and all conditions to such redemption, other than the deposit of funds with the Trustee have been satisfied, each Holder will have the right to require the Company 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 101.0% of the aggregate principal amount thereof plus accrued and unpaid interest, to but excluding the
date of purchase; provided that if the repurchase date is after the record date but on or before the related interest payment date, then Holders of the Notes who hold as of the record date will receive interest on the repurchase date. 

Upon certain Asset Dispositions, the Company may be required to use the Excess Proceeds from such Asset Dispositions to offer to purchase the
maximum aggregate principal amount of Notes (that is $2,000 or an integral multiple of $1,000 in excess thereof) and, at the Company’s option, Pari Passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in
an amount equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest, to the date fixed for the closing of such offer, in accordance with the procedures set forth in Section 3.5 and in
Article V of the Indenture. 

  
 A-6 








 10.    Denominations; Transfer; Exchange 

The Notes shall be issuable only in fully registered 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) 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 (2) 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. 
 11.    Persons Deemed Owners 

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

12.    Unclaimed Money 

If money for the payment of principal, premium, if any, interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the
money back to the Company at its written request unless an abandoned property law designates another Person to receive such money. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for
payment as general creditors unless an abandoned property law designates another person for payment. 
 13.    Discharge and
Defeasance 
 Subject to certain exceptions and conditions set forth in the Indenture, the Company at any time may terminate some or all
of its obligations under the Notes and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any and interest on the Notes to redemption or maturity, as the case may be.

 14.    Amendment, Supplement, Waiver 

Subject to certain exceptions contained in the Indenture, the Indenture, the Note Guarantees and the Notes may be amended, or a Default
thereunder may be waived, with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company, the Guarantors and the Trustee may amend or supplement
the Indenture and the Notes as provided in the Indenture. 
 15.    Defaults and Remedies 

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company
or certain Guarantors) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 30.0% in principal amount of the outstanding Notes by notice to the Company and the Trustee may declare the principal of and accrued
and unpaid interest, and any other monetary obligations on all the Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal, interest, and other monetary obligations will be due and payable
immediately. If a bankruptcy, insolvency or reorganization of the Company or certain Guarantors occurs and is continuing, the principal of and accrued and unpaid interest and any other monetary obligations 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 any such acceleration
with respect to the Notes and its consequences. 

  
 A-7 








 16.    Trustee Dealings with the Company 

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 Company, 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 Company;
provided, however, that if the Trustee acquires any conflicting interest, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to
continue acting as Trustee or (iii) resign. 
 17.    No Recourse Against Others 

No director, officer, employee, incorporator or shareholder of the Company or any of its Subsidiaries or Affiliates, as such (other than the
Company and the Guarantors), shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or the Indenture 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. Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the SEC that such a waiver is against public policy. 
 18.    Authentication 

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Note. 
 19.    Abbreviations 

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the
entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gift to Minors Act). 

20.    CUSIP and ISIN Numbers 

The Company has caused CUSIP and ISIN numbers, if applicable, to be printed on the Notes and has directed the Trustee to use CUSIP and ISIN
numbers, if applicable, in notices of redemption or purchase as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption or purchase and
reliance may be placed only on the other identification numbers placed thereon. 
 21.    Governing Law 

This Note shall be governed by, and construed in accordance with, the laws of the State of New York. 

The Company will furnish to any Holder upon written request and without charge to the Holder a copy of the Indenture. Requests may be

 [REVERSE SIDE OF NOTE] 

VERSUM MATERIALS, INC. 5.500% SENIOR NOTES DUE 2024 

Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. 

1.    Interest 
 The
Company promises to pay interest on the principal amount of this Note at 5.500% per annum from September 30, 2016 until maturity. The Company will pay interest semi-annually in arrears every March 15 and September 15 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 the date of issuance; provided, that the first Interest Payment Date shall be March 15, 2017. The Company shall pay interest on overdue principal at the rate specified herein, and it 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. 

2.    Method of Payment 

By no later than 11:00 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 Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium, 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 March 1 and September 1 at the office or agency of the Company
maintained for such purpose pursuant to Section 2.3 of the Indenture. The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent or Registrar designated by
the Company 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 Company 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 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 in accordance with the Notes Register, or
by wire transfer to a 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 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. 







 3.    Paying Agent and Registrar 

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

4.    Indenture 
 The
Company issued the Notes under an Indenture dated as of September 30, 2016 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the guarantors named
therein 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. In
the event of a conflict between the terms of the Notes and the terms of the Indenture, the terms of the Indenture shall control. 
 The
Notes are senior obligations of the Company. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 5.500% Senior Notes due 2024 referred to in the
Indenture. The Notes include (i) $425,000,000 principal amount of the Company’s 5.500% Senior Notes due 2024 issued under the Indenture on September 30, 2016 (the “Initial Notes”) and (ii) if and when issued,
additional Notes that may be issued from time to time under the Indenture subsequent to September 30, 2016 (the “Additional Notes”) as provided in Section 2.1(a) of the Indenture. The Initial Notes and
the Additional Notes shall be considered collectively as a single class for all purposes of the Indenture; provided that the Additional Notes will not be issued with the same CUSIP as the existing Notes unless such Additional Notes are

making of payments for consents, the entering into of agreements that restrict distribution from restricted subsidiaries and the consummation of mergers and consolidations. The Indenture also imposes requirements with respect to the provision
of financial information and the provision of guarantees of the Notes by certain subsidiaries.

the Company or any of its Restricted Subsidiaries); provided further that each such redemption occurs not later than 180 days after the date of closing of the related Equity Offering. The Trustee shall select the Notes to be
purchased in the manner described under Sections 5.1 through 5.6 of the Indenture. 

(c)    Except pursuant to clauses (a) and (b) of this paragraph 7, the Notes will not be redeemable at the

offer in lieu of the Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party shall have the right upon not less than 15 nor more than 60 days’ prior notice, with a copy to the

to the Notes 
 8.    [Reserved]. 

9.    Repurchase Provisions 

If a Change of Control occurs, unless the Company has previously or substantially concurrently therewith delivered a redemption notice with
respect to all the outstanding Notes and all conditions to such redemption, other than the deposit of funds with the Trustee have been satisfied, each Holder will have the right to require the Company 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 101.0% of the aggregate principal amount thereof plus accrued and unpaid interest, to but excluding the
date of purchase; provided that if the repurchase date is after the record date but on or before the related interest payment date, then Holders of the Notes who hold as of the record date will receive interest on the repurchase date. 

Upon certain Asset Dispositions, the Company may be required to use the Excess Proceeds from such Asset Dispositions to offer to purchase the
maximum aggregate principal amount of Notes (that is $2,000 or an integral multiple of $1,000 in excess thereof) and, at the Company’s option, Pari Passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in
an amount equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest, to the date fixed for the closing of such offer, in accordance with the procedures set forth in Section 3.5 and in
Article V of the Indenture. 







 10.    Denominations; Transfer; Exchange 

The Notes shall be issuable only in fully registered 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) 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 (2) 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. 
 11.    Persons Deemed Owners 

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

12.    Unclaimed Money 

If money for the payment of principal, premium, if any, interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the
money back to the Company at its written request unless an abandoned property law designates another Person to receive such money. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for
payment as general creditors unless an abandoned property law designates another person for payment. 
 13.    Discharge and
Defeasance 
 Subject to certain exceptions and conditions set forth in the Indenture, the Company at any time may terminate some or all
of its obligations under the Notes and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any and interest on the Notes to redemption or maturity, as the case may be.

 14.    Amendment, Supplement, Waiver 

Subject to certain exceptions contained in the Indenture, the Indenture, the Note Guarantees and the Notes may be amended, or a Default
thereunder may be waived, with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company, the Guarantors and the Trustee may amend or supplement
the Indenture and the Notes as provided in the Indenture. 
 15.    Defaults and Remedies 

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company
or certain Guarantors) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 30.0% in principal amount of the outstanding Notes by notice to the Company and the Trustee may declare the principal of and accrued
and unpaid interest, and any other monetary obligations on all the Notes 







 
to be due and payable immediately. Upon the effectiveness of such declaration, such principal, interest, and other monetary obligations will be due and payable immediately. If a
bankruptcy, insolvency or reorganization of the Company or certain Guarantors occurs and is continuing, the principal of and accrued and unpaid interest and any other monetary obligations 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 any such acceleration with respect to the
Notes and its consequences. 
 16.    Trustee Dealings with the Company 

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 Company, 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 Company;
provided, however, that if the Trustee acquires any conflicting interest, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to
continue acting as Trustee or (iii) resign. 
 17.    No Recourse Against Others 

No director, officer, employee, incorporator or shareholder of the Company or any of its Subsidiaries or Affiliates, as such (other than the
Company and the Guarantors), shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or the Indenture 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. Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the SEC that such a waiver is against public policy. 
 18.    Authentication 

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Note. 
 19.    Abbreviations 

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by
the entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gift to Minors Act). 

20.    CUSIP and ISIN Numbers 

The Company has caused CUSIP and ISIN numbers, if applicable, to be printed on the Notes and has directed the Trustee to use CUSIP and ISIN
numbers, if applicable, in notices of redemption or purchase as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption or purchase and
reliance may be placed only on the other identification numbers placed thereon. 







 21.    Governing Law 

This Note shall be governed by, and construed in accordance with, the laws of the State of New York.
