For all purposes of this Second Supplemental Indenture: 

“Attributable Debt” means, as to any particular lease under which the Company or a Restricted Subsidiary is at the time
liable, other than a Capital Lease, and at any date as of which the amount of such lease is to be determined, the total net amount of rent required to be paid by the Company or such Restricted Subsidiary, as the case may be, under such lease during
the initial term of such lease as determined in accordance with GAAP, discounted from the last date of such initial term to the date of determination at a rate per annum equal to the discount rate which would be applicable to a Capital Lease with a
like term in accordance with GAAP. The net amount of rent required to be paid under any such lease for any such initial term shall be the aggregate amount of rent payable by the lessee with respect to such initial term after excluding amounts
required to be paid on account of insurance, taxes, assessments, utility, operating and labor costs and similar charges. If any such lease is terminable by the lessee upon the payment of a penalty, such net amount shall also include the amount of
such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. “Attributable Debt” means, as to a Capital Lease under which the Company or a
Restricted Subsidiary is at the time liable and at any date as of which the amount of such Capital Lease is to be determined, the capitalized amount of such Capital Lease that would appear on the face of the consolidated balance sheet of the Company

 “Capital Lease” means any Indebtedness represented by a lease obligation
of the Company or a Restricted Subsidiary incurred with respect to real property or equipment acquired or leased by the Company or such Restricted Subsidiary and used in its business that is required to be recorded as a capital lease on the face of

(2) any sale, lease, exchange or other transfer (other than by way of merger or consolidation), in one transaction or a series
of related transactions, of all or substantially all of the assets of the Company and the assets of its Subsidiaries, taken as a whole, to any person or group of related persons for the purpose of Section 13(d)(3) of the Exchange Act, other than the
Company or one of its Subsidiaries, 
 (3) the Company consolidates with, or merges with or into, any Person, or any Person

property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving
Person immediately after giving effect to such transaction,

office who either were members of the Board of Directors at the beginning of such period or whose election as members of the Board of Directors was previously so approved (either by a specific vote or by approval of the Company’s proxy
statement in which such member was named as a nominee for election as a director, without objection to such nomination) or subsequently ratified, or 

(5) the adoption of a plan relating to the liquidation, dissolution or winding up of the Company. 

Notwithstanding the foregoing, a transaction or series of related transactions will not be considered to be a Change of Control if
(1) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (2)(a) immediately following that transaction, the direct or indirect holders of the Voting Stock of the holding company are substantially the same as
the holders of the Company’s Voting Stock immediately prior to that transaction or (b) immediately following that transaction, no person or group (as used in Section 13(d)(3) of the Exchange Act) is the beneficial owner (as defined in
Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Voting Stock of such holding company.

assumption, renewal, extension or replacement, and after giving effect to such creation, incurrence, assumption, renewal, extension or replacement, Exempted Debt does not exceed 15% of Consolidated Net Tangible Assets. 

Section 2.2 Limitation on Sale and Leaseback Transactions. The Company will not, and will not permit any Restricted
Subsidiary to, sell or otherwise transfer, directly or indirectly, except to the Company or a Restricted Subsidiary, any Principal Property as an entirety, or any substantial portion of any Principal Property, with the intention of taking back a
lease of such Principal Property, or substantial portion of such Principal Property, except a lease for a period of three years or less; provided, however, that the Company or any Restricted Subsidiary may sell any Principal Property, or any
substantial portion of any Principal Property, and lease it back for a longer period (i) if the Company or such Restricted Subsidiary would be entitled, pursuant to the provisions described above in clauses (a) through (o) under
Section 2.1 of this Second Supplemental Indenture, to create a mortgage, pledge or other lien on such Principal Property, or substantial portion of such Principal Property, to be leased securing Funded Debt in an amount equal to the
Attributable Debt with respect to such sale and leaseback transaction without equally and ratably securing the outstanding Notes or (ii) if (A) the Company promptly informs the Trustee of such sale, (B) the net proceeds of such sale are at
least equal to the fair value (as determined by a resolution of the Board of Directors) of such Principal Property, or substantial portion of such Principal Property, and (C) the Company causes an amount equal to the net proceeds of such sale
to be applied to the retirement, within 180 days after receipt of such proceeds, of Funded Debt created, incurred, assumed or guaranteed by the Company or a Restricted Subsidiary; provided, further, that, in lieu of applying all of or any part of
such net proceeds to such retirement, the Company may, within 75 days after such sale, deliver or cause to be delivered to the applicable trustee for cancellation either debentures or notes evidencing Funded Debt created, incurred, assumed or
guaranteed by the Company or any Restricted Subsidiary previously authenticated and delivered by the applicable trustee, and not previously tendered for sinking fund purposes or called for a sinking fund or otherwise applied as a credit against an
obligation to redeem or retire such debentures or notes, and to deliver an Officer’s Certificate to the Trustee stating that the Company elects to deliver or cause to be delivered such 

  
 11 








 
debentures or notes in lieu of retiring Funded Debt created, incurred, assumed or guaranteed by the Company or any Restricted Subsidiary. If the Company shall so deliver or cause to be delivered
such debentures or notes and such Officer’s Certificate, the amount of cash which the Company will be required to apply to the retirement of Funded Debt under this provision shall be reduced by an amount equal to the aggregate of the then
applicable optional redemption prices (not including any optional sinking fund redemption prices) of such debentures or notes or, if there are no such optional redemption prices, the principal amount of such debentures or notes, provided, that in
the case of debentures or notes which provide for an amount less than the principal amount of such debentures or notes to be due and payable upon an acceleration of the maturity of such debentures or notes, such amount of cash shall be reduced by
the amount of principal of such debentures or notes that would be due and payable as of the date of such acceleration of the maturity of such debentures or notes in accordance with the terms of the indenture pursuant to which such debentures or
notes were issued. 
 Notwithstanding the foregoing, the Company or any Restricted Subsidiary may enter into sale and leaseback transactions
in addition to those permitted by this Section 2.2 and without any obligation for the Company or any Restricted Subsidiary to retire any Funded Debt or to deliver or cause to be delivered debentures or notes evidencing Funded Debt to the
applicable trustee for cancellation, provided, that at the time of entering into such sale and leaseback transactions and after giving effect to such transactions, Exempted Debt does not exceed 15% of Consolidated Net Tangible Assets. 

Section 2.3 Offer to Repurchase Upon Change of Control Repurchase Event. (a) If a Change of Control Repurchase Event occurs,
unless the Company has exercised its right to redeem the Notes in full in accordance with Section 6.3 of this Second Supplemental Indenture, the Company shall be required to make an offer to each Holder of Notes to repurchase all or, at the
election of such Holder, any part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes for cash at a repurchase price equal to 101% of the principal amount of such Notes to be
repurchased plus unpaid interest, if any, accrued thereon to, but not including, the repurchase date. Notwithstanding the foregoing, interest shall be payable to Holders of the Notes on the Record Date applicable to an Interest Payment Date falling
on or before a repurchase date. 
 (b) Within 30 days following any Change of Control Repurchase Event or, at the Company’s option,
prior to any Change of Control, but after the public announcement of a transaction or transactions that constitute or may constitute a Change of Control, the Company shall mail a notice (the “Change of Control Offer”) to each Holder
of Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase all of such Notes on the repurchase date specified in the notice,
which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, except in the case of an offer made in advance of a Change of Control Repurchase Event in accordance with Section 2.3(g) of this Second
Supplemental Indenture. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase such Notes is conditioned on the Change of Control Repurchase Event occurring on or prior to the
repurchase date specified in the notice. Holders electing to have their Notes repurchased pursuant to a Change of Control Offer shall be required to surrender their Notes, with the form entitled “Option of Holder to Elect Repurchase” on
the 

  
 12 








 
reverse of their Notes completed, to the Trustee or a Paying Agent at the address specified in the notice, or transfer their Notes to the Trustee or such Paying Agent by book-entry transfer
pursuant to the applicable procedures of the Trustee or such Paying Agent, prior to the close of business on the third Business Day prior to the repurchase date. 

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this Section 2.3 or the related provisions in the Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations under the provisions of this Section 2.3 or the related provisions in the Notes by virtue of such conflict. 
 (d) On the
repurchase date, the Company shall, to the extent lawful: 
 (i) accept for payment all Notes or portions of Notes (equal to
a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) properly tendered by the Holders thereof pursuant to the Company’s offer; 

(ii) deposit with the Trustee or one or more Paying Agents an amount equal to the aggregate repurchase price in respect of all
Notes or portions of Notes properly tendered by the Holders thereof; and 
 (iii) deliver or cause to be delivered to the
Trustee the Notes properly accepted by the Company, together with an Officer’s Certificate stating the aggregate principal amount of Notes being repurchased. 

(e) The Trustee or one or more Paying Agents shall promptly mail to each Holder of Notes properly tendered the repurchase price for such Notes,
and the Trustee, upon the Company’s execution and delivery of the related Notes, shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unrepurchased portion of
any Notes properly tendered, provided, that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 

(f) The Company shall not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes
such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to be made by the Company and such third party purchases all Notes properly tendered and not withdrawn by the Holders thereof under its offer.

 (g) Notwithstanding anything to the contrary herein, an offer to repurchase the Notes may be made in advance of a Change of Control
Repurchase Event, conditional upon the occurrence of such Change of Control Repurchase Event. 
 (h) If Holders of not less than 90% in
aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making an offer to repurchase the Notes upon a Change of Control


  
 13 








 
Repurchase Event in lieu of the Company as described in Section 2.3(f) of this Second Supplemental Indenture, repurchases all of the Notes validly tendered and not withdrawn by such Holders, the
Company or such third party will have the right, upon not less than 30 nor more than 60 days’ prior written notice, given not more than 30 days following such repurchase pursuant to the Change of Control Offer described above, to repurchase all
Notes that remain outstanding following such repurchase at a price in cash equal to 101% of the principal amount of such Notes to be repurchased plus unpaid interest, if any, accrued thereon to, but not including, the repurchase date. 

Section 2.4 Merger, Consolidation and Sale of Assets of Subsidiary Guarantors. If, after the date of this Second Supplemental
Indenture, any Wholly-Owned Domestic Subsidiary of the Company provides a Subsidiary Guarantee with respect to the Notes pursuant to Article IV of this Second Supplemental Indenture, such Subsidiary Guarantor shall not consolidate or merge with or
into any other entity, or sell, convey, transfer or lease all or substantially all its assets to another entity, unless such Subsidiary Guarantor’s Subsidiary Guarantee is released under the circumstances described in Section 4.1(d) of this
Second Supplemental Indenture or: 
 (1) either such Subsidiary Guarantor shall be the continuing entity, or the successor, transferee or
lessee entity (if other than such Subsidiary Guarantor) shall, pursuant to a supplemental indenture, executed and delivered by such entity prior to or simultaneously with such consolidation, merger, sale, conveyance, transfer or lease, expressly
assume all obligations under the Subsidiary Guarantee to be performed or observed by such Subsidiary Guarantor; and 
 (2) such Subsidiary
Guarantor shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease and such supplemental indenture comply with this
Section 2.4 and that all conditions precedent herein provided for relating to such transaction have been complied with.

Securities other than the Notes and other than a covenant or condition of default in the performance of which is elsewhere in this Section specifically addressed), which failure shall not have been remedied, or without provision deemed to be
adequate for the remedying thereof having been made, for a period of 90 days after written notice shall have been given to the Company by the Trustee or shall have been given to the Company and the Trustee by Holders of 25% or more in aggregate
principal amount of the Notes then Outstanding, specifying such failure, requiring the Company to remedy the same and stating that such notice is a “Notice of Default” hereunder;

(g) default by the Company or any of its Subsidiaries under any bond, debenture, note, mortgage, indenture or instrument evidencing or securing
Indebtedness that is recourse to the Company’s assets or those of its Subsidiaries, which default (a) shall constitute a failure to pay an aggregate principal amount exceeding $75.0 million of such Indebtedness when due and payable

(d) above shall constitute an Event of Default hereunder until the Trustee or the Holders of 25% or more in aggregate principal amount of the Notes Outstanding, notify the Company (and the Trustee in case of notice by the Holders) of the
Default, specifying the Default, requiring the Company to remedy the same and stating that such notice is a “Notice of Default” hereunder. 

ARTICLE IV 
 GUARANTEES

 Section 4.1 Subsidiary Guarantees. (a) If, after the date of this Second Supplemental Indenture, any Wholly-Owned
Domestic Subsidiary of the Company executes and delivers a guarantee of, or otherwise becomes obligated with respect to, any Debt of the Company, then the Company shall cause such Wholly-Owned Domestic Subsidiary to guarantee the Company’s
obligations under the Indenture and under the Notes on a senior unsecured basis (each, a “Subsidiary Guarantee”). For the avoidance of doubt, in the event that any Debt of the Company contains a provision that would require
one or more Wholly-Owned Domestic Subsidiaries of the Company to execute and deliver a guarantee, or otherwise become obligated with respect to, such Debt upon the occurrence or satisfaction of specified conditions, such Wholly-Owned Domestic
Subsidiary shall not be deemed to have executed and delivered a guarantee, or otherwise become obligated with respect to, such Debt until such time as such conditions shall have been satisfied and such Wholly-Owned Domestic Subsidiary is required to
guarantee, or otherwise be obligated with respect to, such Debt. 
 (b) If a Wholly-Owned Domestic Subsidiary becomes obligated pursuant to
Section 4.1(a) to guarantee the Notes after the initial issue date of the Notes, then the Company shall cause such Wholly-Owned Domestic Subsidiary, within twenty Business Days, to (A) execute and deliver to the Trustee a supplemental
indenture, in form reasonably satisfactory to the Trustee, pursuant to which such Wholly-Owned Domestic Subsidiary shall guarantee all of the Company’s obligations under the Indenture and under the Notes on a senior unsecured basis and
(B) deliver to the Trustee an Opinion of Counsel to the effect that each of such supplemental indenture and such Subsidiary Guarantee has been duly authorized, executed and delivered by, and constitutes a valid, legally binding and enforceable
obligation of, such Wholly-Owned Domestic Subsidiary, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws or by general principles of equity. 

(c) Any Subsidiary Guarantee shall rank equally and ratably with all other unsecured and unsubordinated Indebtedness of the applicable
Subsidiary Guarantor from time to time outstanding, including the Debt that triggers such Subsidiary Guarantee if such Debt is senior unsecured Indebtedness. 

  
 16 








 (d) The Holders of the Notes shall be deemed to have consented to the release of the Subsidiary
Guarantee of the Notes and the Indenture provided by a Subsidiary Guarantor, without any action required on the part of the Trustee or any Holder of the Notes, upon such Subsidiary Guarantor ceasing to be a guarantor or obligor under any Debt of the
Company. Accordingly, if a Subsidiary Guarantor is released from its guarantee of all Debt of the Company and other obligations as a borrower or guarantor thereunder, such Subsidiary Guarantor’s Subsidiary Guarantee of the Notes and the
Indenture shall automatically terminate and the Company shall give prompt written notice to the Trustee of the release of such Subsidiary Guarantor from its Subsidiary Guarantee of the Notes and the Indenture. 

In addition, a Subsidiary Guarantor shall be automatically released from all of its obligations under its Subsidiary Guarantee upon
(1) such Subsidiary Guarantor no longer being wholly-owned by the Company and its Subsidiaries or such Subsidiary Guarantor redomiciling outside the United States of America, any state thereof or the District of Columbia or (2) the sale or
other transfer of all or substantially all of the assets of such Subsidiary Guarantor to a Person other than an Affiliate of the Company that is not another Subsidiary Guarantor. A Subsidiary Guarantee also will be automatically released if the
Company exercises its option to discharge its obligations with respect to the Notes as set forth in Section 12.03 of the Base Indenture, or if the Company’s obligations under the Indenture are discharged as set forth in Section 12.02
of the Base Indenture. 
 At the Company’s written instruction, the Trustee shall execute and deliver any documents, instructions or
instruments evidencing any such automatic release of a Subsidiary Guarantor. 
 The obligations of a Subsidiary Guarantor under its
Subsidiary Guarantee that are released as described in this Section 4.1(d) shall be reinstated if such Subsidiary Guarantor again executes and delivers a guarantee of, or otherwise becomes obligated with respect to, any Debt of the Company. 

Section 4.2 Limitation of Guarantees. Notwithstanding any provision of any Subsidiary Guarantee, any Subsidiary Guarantee of a
Subsidiary Guarantor shall hereby be limited to the extent, if any, required so that its obligations under such Subsidiary Guarantee shall not be subject to avoidance under Section 548 of the Federal Bankruptcy Code or under any applicable
state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law. 
 ARTICLE V 

SATISFACTION AND DISCHARGE 
  

Section 5.1 Amendment of Satisfaction and Discharge of the Indenture 

Section 12.02 of the Base Indenture is hereby superseded and replaced with respect to the Notes with the following: 

Satisfaction and Discharge of Indenture. The Indenture, with respect to the Notes (if all series of Securities issued under the
Indenture are not to be affected), shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or 

  
 17 








 
exchange of such Notes expressly provided for in the Indenture and the rights of the Holders of the Notes to receive, the principal of and premium, if any, and interest on such Notes as and when
the same shall become due and payable and except as otherwise provided in the last paragraph of this Section), and the Trustee, at the request and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of the Indenture with respect to the Notes, when, 
 (a) either: 

(i) all Notes theretofore authenticated and delivered (other than (A) Notes that have been destroyed, lost or stolen and
that have been replaced or paid as provided in Section 3.07 of the Base Indenture and (B) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust, as provided in Section 6.03(e) of the Base Indenture) have been delivered to the Trustee for cancellation; or 

(ii) all Notes not theretofore delivered to the Trustee for cancellation, 

(A) have become due and payable, or 

(B) will become due and payable at their Stated Maturity within one year, or 

(C) if redeemable at the option of the Company (including, without limitation, by operation of any mandatory sinking fund), 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, 

and the Company, in the case of (A), (B) or (C) above, has irrevocably deposited or caused to be deposited with the Trustee funds in trust for the
purpose an amount in cash in the Currency in which the Notes are payable (subject to Section 12.08 of the Base Indenture) sufficient, without consideration of any reinvestment, to pay and discharge the entire indebtedness on such Notes for
principal and premium, if any, and interest to the date of such deposit (in the case of Notes that have become due and payable) or to the Stated Maturity thereof or, in the case of Notes which are to be called for redemption as contemplated by
(C) above, the applicable Redemption Date, as the case may be, and including any mandatory sinking fund payments as and when the same shall become due and payable. 

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Notes; and 

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent
provided for in the Indenture relating to the satisfaction and discharge of the Indenture with respect to the Notes have been complied with. 

  
 18 








 Notwithstanding the satisfaction and discharge of the Indenture with respect to the Notes, the
obligations of the Company to the Trustee under Section 11.01 of the Base Indenture, the provisions of Sections 3.04, 3.05, 3.06, 3.07, 3.10, 6.02 and 6.03 of the Base Indenture and Article
XII of the Base Indenture and, if the Notes are to be redeemed prior to their Stated Maturity (including, without limitation, pursuant to a mandatory sinking fund), the provisions of Article IV of the Base Indenture, and, if the Notes
are convertible into or exchangeable for other securities or property, the rights of the Holders of such Notes to convert or exchange, and the obligations of the Company to convert or exchange, such Notes into other securities or property, and,
if money shall have been deposited with the Trustee pursuant to clause (a) of this Section, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Base Indenture shall survive such satisfaction and discharge. 

ARTICLE VI 
 FORM AND
TERMS OF THE NOTES 
 This Article VI applies solely to the Notes and shall not affect the rights under the Indenture of the Holders of
Securities of any other series. 
 Section 6.1 Form and Dating. 

The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A attached hereto. The
Notes shall be executed on behalf of the Company by an Officer of the Company as specified in Section 3.03 of the Base Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Note
shall be dated the date of its authentication. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

The terms and notations contained in the Notes shall constitute, and are hereby expressly made, a part of the Indenture; and the Company and
the Trustee, by their execution and delivery of this Second Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby; provided, that, to the extent of any inconsistency between the terms and provisions in the
Indenture and those contained in the Notes, the Notes shall govern. 
 (a) Global Notes. The Notes designated herein shall be issued
initially in the form of one or more fully-registered permanent Global Securities (each, a “Global Note”), which shall be held by the Trustee as custodian for The Depository Trust Company, New York, New York (the
“Depositary”), and registered in the name of Cede & Co., the Depositary’s nominee, duly executed by the Company and authenticated by the Trustee. The aggregate principal amount of outstanding Notes represented by a
Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided. 

(b) Paying Agent and Security Registrar. The Company appoints the Trustee as its initial Paying Agent and Security Registrar for the
Notes. 

  
 19 








 Section 6.2 Certain Terms of the Notes. 

In addition to the terms of the Notes established elsewhere in this Second Supplemental Indenture and the form of Note attached hereto as
Exhibit A, the Notes have the following terms: 
 (a) Title. The Notes shall constitute a series of Securities having
the title “3.950% Senior Notes due 2027.” 
 (b) Principal Amount. The aggregate principal amount of the Notes that
may be initially authenticated and delivered under the Indenture shall be FOUR HUNDRED MILLION DOLLARS ($400,000,000). The Company may, from time to time, without notice to, or the consent of, the Holders of the Notes, create and issue additional
Securities (“Additional Securities”) ranking equally and ratably with, and having the same interest rate, maturity and other terms as, the originally issued Notes (other than the issue date and, under certain circumstances, the
issue price, the date from which interest begins to accrue and the first Interest Payment Date). Any such Additional Securities will be consolidated, and constitute a single series of Securities, with the originally issued Notes for all purposes
under the Indenture. 
 (c) Stated Maturity Date. The entire outstanding principal of the Notes shall mature and be payable on
February 15, 2027 (the “Stated Maturity Date”), subject to Sections 2.3 and 6.3 of this Second Supplemental Indenture. 

(d) Interest Rate. The rate at which the Notes shall bear interest shall be 3.950% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months; the date from which interest shall accrue on the Notes shall be February 16, 2017 or the most recent Interest Payment
Date to which interest has been paid or duly provided for; the Interest Payment Dates for the Notes shall be February 15 and August 15 of each year, beginning on August 15, 2017. The interest rate payable on the Notes will be subject
to adjustments upon the occurrence of certain ratings-based events as set forth in Section 6.2(e) of this Second Supplemental Indenture. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will be paid to
the Persons in whose names the Notes (or one or more predecessor Notes) is registered at the close of business on the February 1 or August 1 (whether or not a Business Day) immediately preceding the applicable Interest Payment Date. 

(e) Interest Rate Adjustment. (i) The interest rate payable on the Notes will be subject to adjustments from time to time if
either Moody’s or S&P or, if either Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside the Company’s control, a “nationally recognized statistical rating
organization” selected pursuant to the definition of Rating Agency (a “substitute rating agency”), downgrades (or downgrades and subsequently upgrades) the credit rating assigned to the Notes, in the manner described below.

 (ii) If the rating from Moody’s (or any substitute rating agency therefor) of the Notes is decreased to a rating set forth in the
immediately following table, the interest rate on the Notes will increase such that it will equal the interest rate payable on the Notes on the date of this Second Supplemental Indenture plus the percentage set forth opposite the ratings from the
table below: 

  
 20 








 Moody’s Rating* Percentage 
  


					
	 Ba1
	  	 	0.25	% 
	 Ba2
	  	 	0.50	% 
	 Ba3
	  	 	0.75	% 
	 B1 or below
	  	 	1.00	% 

  

	*	Including the equivalent ratings of any substitute rating agency. 

 (iii) If the rating from
S&P (or any substitute rating agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase such that it will equal the interest rate payable on the Notes on the
date of this Second Supplemental Indenture plus the percentage set forth opposite the ratings from the table below: 
 S&P Rating* Percentage

  

					
	 BB+
	  	 	0.25	% 
	 BB
	  	 	0.50	% 
	 BB-
	  	 	0.75	% 
	 B+ or below
	  	 	1.00	% 

  

	*	Including the equivalent ratings of any substitute rating agency. 

 (iv) If at any time the
interest rate on the Notes has been increased and either Moody’s or S&P (or, in either case, a substitute rating agency therefor), as the case may be, subsequently upgrades its rating of the Notes to any of the threshold ratings set forth
above, the interest rate on the Notes will be decreased such that the interest rate for the Notes equals the interest rate payable on the Notes on the date of this Second Supplemental Indenture plus the percentages set forth opposite the ratings
from the tables in paragraphs (ii) and (iii) above in effect immediately following the upgrade in rating. If Moody’s (or any substitute rating agency therefor) subsequently upgrades its rating of the Notes to Baa3 (or its equivalent, in
the case of a substitute rating agency) or higher, and S&P (or any substitute rating agency therefor) upgrades its rating to BBB- (or its equivalent, in the case of a substitute rating agency) or higher,
the interest rate on the Notes will be decreased to the interest rate payable on the Notes on the date of this Second Supplemental Indenture (and if one such upgrade occurs and the other does not, the interest rate on the Notes will be decreased so
that it does not reflect any increase attributable to the upgrading Rating Agency). In addition, the interest rates on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent downgrade in the
ratings by either or both Rating Agencies) if the Notes become rated Baa2 and BBB (or the equivalent of either such rating, in the case of a substitute rating agency) or higher by Moody’s and S&P (or, in either case, a substitute rating
agency therefor), respectively (or one of these ratings if the Notes are only rated by one Rating Agency). 

  
 21 








 (v) Each adjustment required by any downgrade or upgrade in a rating set forth above, whether
occasioned by the action of Moody’s or S&P (or, in either case, a substitute rating agency therefor), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Notes be reduced to below
the interest rate payable on the Notes on the date of this Second Supplemental Indenture or (2) the total increase in the interest rate on the Notes exceed 2.00% above the interest rate payable on the Notes on the date of this Second
Supplemental Indenture. 
 (vi) No adjustments in the interest rate of the Notes shall be made solely as a result of a Rating Agency ceasing
to provide a rating of the Notes. If at any time Moody’s or S&P ceases to provide a rating of the Notes, the Company will use its commercially reasonable efforts to obtain a rating of the Notes from a substitute rating agency, to the extent
one exists, and if a substitute rating agency exists, for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the tables in paragraphs (ii) and (iii) above (a) such substitute rating agency will
be substituted for the last Rating Agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative rating scale used by such substitute rating agency to assign ratings to senior unsecured debt will be
determined in good faith by an independent investment banking institution of national standing appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table in paragraph (ii) or (iii) above
with respect to such substitute rating agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate on the Notes will increase or decrease, as the case
may be, such that the interest rate equals the interest rate payable on the Notes on the date of this Second Supplemental Indenture plus the appropriate percentage, if any, set forth opposite the rating from such substitute rating agency in the
applicable table in paragraph (ii) or (iii) above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other Rating Agency). 

(vii) For so long as only one Rating Agency provides a rating of the Notes, any subsequent increase or decrease in the interest rate of the
Notes necessitated by a reduction or increase in the rating by the Rating Agency providing the rating shall be twice the percentage set forth in the applicable table in paragraph (ii) or (iii) above. For so long as neither Moody’s nor
S&P (or, in either case, a substitute rating agency therefor) provides a rating of the Notes, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Notes on the date of
this Second Supplemental Indenture. 
 (viii) Any interest rate increase or decrease described above will take effect from the first Interest
Payment Date following the date on which a rating change occurs that requires an adjustment in the interest rate. As such, interest will not accrue at such increased or decreased rate until the Interest Payment Date immediately following the date on
which a rating change occurs. If Moody’s or S&P (or, in either case, a substitute rating agency therefor) changes its rating of the Notes more than once prior to any particular Interest Payment Date, the last change by such Ratings Agency
prior to such Interest Payment Date will control for purposes of any interest rate increase or decrease with respect to the Notes described above relating to such Rating Agency’s action. If the interest rate payable on the Notes is increased as
described above, the term “interest,” as used with respect to the Notes under the Indenture or the Notes, will be deemed to include any such additional interest unless the context otherwise requires. 

  
 22 








 (f) Currency. The currency of denomination of the Notes is United States dollars. Payment
of principal of, and premium, if any, and interest on, the Notes will be made in United States dollars. 
 (g) Sinking Fund
Provisions. The Notes will not be entitled to the benefit of, or be subject to, any sinking fund provisions. 
 (h) Defeasance and
Covenant Defeasance. The Notes are subject to defeasance and covenant defeasance at the option of the Company as provided in the Base Indenture. 

Section 6.3 Optional Redemption. 

(a) Applicability of Article IV. The provisions of Article IV of the Base Indenture shall apply to the Notes, as supplemented by Section
6.3(b) of this Second Supplemental Indenture. 
 (b) Redemption Price. The Redemption Price for Notes that are redeemed prior to
November 15, 2026 (i.e., three months prior to the Stated Maturity Date of the Notes) (the “Par Call Date”), will be equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of
the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed that would have been payable in respect of such Notes calculated as if the Stated Maturity Date of such Notes was the Par Call Date,
discounted to the applicable Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 0.250%, or 25
basis points, plus in each case unpaid interest, if any, accrued thereon to, but not including, such Redemption Date. In addition, the Redemption Price for the Notes that are redeemed on or after the Par Call Date will be equal to 100% of the
principal amount of the Notes to be redeemed plus unpaid interest, if any, accrued thereon to, but not including, the Redemption Date. 

ARTICLE VII

 HEXCEL CORPORATION 

3.950% SENIOR NOTES DUE 2027 

Hexcel Corporation, a Delaware corporation (the “Company,” which term includes any successor under the Indenture (as defined
below)), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal amount of FOUR HUNDRED MILLION dollars (or such lesser amount as shall be the outstanding principal amount of this Note shown in
Schedule A hereto) on February 15, 2027 (the “Stated Maturity Date”), unless earlier redeemed or repurchased as described on the reverse hereof, and to pay interest on the outstanding principal amount hereof from, and
including, February 16, 2017, semiannually in arrears on February 15 and August 15 of each year, beginning on August 15, 2017 (each, an “Interest Payment Date”), at the rate of 3.950% per annum, subject to adjustment as
described in Section 6.2(e) of the Second Supplemental Indenture (as defined below), until payment of said principal amount has been made or duly provided for. 

  
 A-1 








 The interest so payable and punctually paid or duly provided for on any Interest Payment Date
shall be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered in the Register applicable to this Note at the close of business on the Record Date for such payment, which shall be the February 1 or
August 1, as the case may be, immediately preceding such Interest Payment Date, regardless of whether such day is a Business Day. Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such
Record Date and may either be paid to the Person in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee
(which shall not be more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment of such Defaulted Interest) established by notice given by mail by or on behalf of the Company to the Holders of the
Notes not less than 10 calendar days prior to the Special Record Date, or may be paid at any time 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, all as more fully provided in the Indenture. Interest on this Note shall be computed on the basis of a 360-day year of twelve 30-day
months. 
 Interest payable on this Note on any Interest Payment Date or the Stated Maturity Date or date of earlier redemption or
repurchase shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date (or from, and including, February 16, 2017, in the case of the initial period) to, but not including, such Interest Payment
Date or the Stated Maturity Date or such date of earlier redemption or repurchase, as the case may be. If any Interest Payment Date or the Stated Maturity Date or date of earlier redemption or repurchase falls on a day that is not a Business Day,
the principal, premium, if any, and/or interest payable with respect to such date shall be made on the next succeeding Business Day with the same force and effect as if made on such date, and no interest shall accrue on the amount so payable for the
period from and after such date to such next succeeding Business Day. 
 The principal of this Note payable on the Stated Maturity Date or
date of earlier redemption or repurchase shall be paid against presentation and surrender of this Note at the office or agency of the Company maintained for that purpose in The Borough of Manhattan, The City of New York. The Company hereby initially
designates the Corporate Trust Office of the Trustee in The City of New York as the office to be maintained by it where Notes may be presented for payment, registration of transfer or exchange, and where notices to or demands upon the Company in
respect of the Notes or the Indenture may be made. 
 Payments of principal, premium, if any, and interest in respect of this Note shall be
made by wire transfer of immediately available funds in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. 

Reference is made to the further provisions of this Note set forth on the reverse hereof. Such further provisions shall for all purposes have
the same effect as though fully set forth at this place.

 [REVERSE OF SECURITY] 

HEXCEL CORPORATION 

3.950% SENIOR NOTE DUE 2027 

This Note is one of a duly authorized issue of debt securities of the Company (collectively, the “Securities”), issued or to
be issued under and pursuant to an Indenture, dated as of August 3, 2015 (as amended or supplemented from time to time, the “Indenture”), duly executed and delivered by the Company to U.S. Bank National Association, as Trustee
(herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the Securities of the series of which this Note is a part), to which Indenture and all indentures supplemental thereto
relating to this Note (including, without limitation, the Second Supplemental Indenture, dated as of February 16, 2017, between the Company and the Trustee (the “Second Supplemental Indenture”)) reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered and for the
definition of capitalized terms used hereby and not otherwise defined. This Note is one of a series designated as the Hexcel Corporation 3.950% Senior Notes due 2027, limited in aggregate principal amount to $400,000,000, except as contemplated in
the Indenture (collectively, the “Notes”). 
 In case an Event of Default with respect to the Notes shall have occurred and
be continuing, the principal amount of the Notes and any premium due on the outstanding Notes and unpaid interest, if any, accrued thereon may be declared, and in certain cases shall automatically become, due and payable immediately, in the manner,
with the effect, and subject to the conditions provided in the Indenture. 
 The Notes may be redeemed at the option of the Company, in
whole at any time or in part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) from time to time, (x) prior to November 15, 2026 (the “Par Call Date”), for cash, at a Redemption
Price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) an amount equal to the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed
that would have been payable in respect of such Notes, calculated as if the Stated Maturity Date of such Notes was the Par Call Date, discounted to the applicable Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate plus 0.250%, or 25 basis points, plus, in each case, unpaid interest, if any, accrued thereon to,
but not including, such Redemption Date, and (y) on or after the Par Call Date, for cash, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, to, but not including,
such Redemption Date. Notwithstanding the foregoing, interest will be payable to Holders of the Notes on the Record Date applicable to an Interest Payment Date falling on or before a Redemption Date. 

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions of the Notes called for redemption. If fewer than all of the Notes are to be redeemed,
the Trustee will select Notes to be redeemed in accordance with the terms specified in the Indenture. 

  
 A-6 








 If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to
redeem the Notes in full, the Company shall be required to make an offer to each Holder of Notes to repurchase all or, at the election of such Holder, any part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess
thereof) of such Holder’s Notes for cash at a repurchase price equal to 101% of the principal amount of such Notes to be repurchased plus unpaid interest, if any, accrued thereon to, but not including, the repurchase date. Notwithstanding the
foregoing, interest shall be payable to Holders of the Notes on the Record Date applicable to an Interest Payment Date falling on or before a repurchase date. Any Change of Control Offer will be made in accordance with the terms specified in the
Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series to be affected voting separately, evidenced as provided in the Indenture, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or modifying in any manner the rights of the Holders of the Securities of such series, subject to certain exceptions requiring the consent of each Holder of Securities affected thereby and certain other
exceptions not requiring the consent of any Holder of Securities. The Indenture also permits the Holders of a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all the Securities of such
series, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults or Events of Default under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such Holder and every subsequent Holder of this Note or portion hereof and of any Note that may be issued in exchange or substitution hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Note. 
 No reference herein to the Indenture and no provision of this Note or of the
Indenture shall affect or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, and premium, if any, and interest on, this Note at the respective due dates herein prescribed. 

This Note is issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.
This Note may be exchanged for a like aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company in The Borough of Manhattan, The City of New York, in the manner and subject to the limitations
provided herein and in the Indenture, but without the payment of any service charge, except for any tax, easement or other governmental charge imposed in connection therewith. 

Upon surrender for registration of transfer of this Note at the office or agency of the Company in The Borough of Manhattan, The City of New
York, one or more new Notes of authorized denominations in a like aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided herein and in the Indenture, without charge, except for any tax,
assessment or other governmental charge imposed in connection therewith. 

  
 A-7 








 The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the
Holder the absolute owner of this Note (whether or not this Note shall be overdue), for the purpose of receiving payment of the principal hereof and any premium hereon and, subject to the provisions on the face hereof, interest hereon, and for all
other purposes, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 

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

Capitalized terms used but not otherwise defined shall have the respective meanings assigned to them in the Indenture (including the Second
Supplemental Indenture).
