or publicly confirm or inform the Trustee in writing that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the

be considered intangible assets under GAAP, including, without limitation, franchises, trademarks, unamortized debt discount and goodwill.

 5 













 
provided, however, that in the case of any such acquisition, construction or improvement, the Liens shall not apply to any property theretofore owned by Holdings or a Restricted

(b)    Section 4.07 of the Original Indenture, entitled “Restrictions as to Dividends and Certain Other
Payments”, is hereby deleted in its entirety and replaced with “[Reserved]” in lieu thereof.

“default under any mortgage, indenture (including this Indenture governing the Notes) or instrument under which there is issued, or which
secures or evidences, any indebtedness for borrowed money of Holdings or any Restricted Subsidiary existing on, or created after, the date of this Indenture, which default shall constitute a failure to pay principal of such indebtedness in an amount
exceeding $200,000,000 when due and payable (other than as a result of acceleration), after expiration of any applicable grace period with respect thereto, or shall have resulted in an aggregate principal amount of such indebtedness exceeding
$200,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such 

  
 6 













 
indebtedness having been discharged or such acceleration having been rescinded or annulled within a period of 30 days after there has been given a notice to Holdings by the Trustee, or to
Holdings and the Trustee by the Holders of at least 25% in principal amount of the Notes of such Series at the time Outstanding;”. 

SECTION 2.04    Further Issues. The Issuers may, from time to time, without the consent of the Holders of the Notes
and in accordance with the Original Indenture and this Twenty-First Supplemental Indenture, create and issue further notes in an unlimited principal amount having the same terms and conditions as the Notes in all respects (or in all respects except
for the issue date and the amount and the date of the first payment of interest) so as to form a single Series with the Notes. The Notes and any such further notes shall be treated as a single class for all purposes under this Indenture; provided
that if any such further notes are not fungible with the Notes for U.S. Federal income tax purposes, such further notes will have a separate CUSIP, ISIN or other identifying number, if applicable. Unless the context otherwise requires, all
references to the Notes shall include any such further notes. 
 SECTION 2.05    Interest and Principal. The
Notes will mature on August 14, 2024 and will bear interest at the rate of 2.875% per annum. The Issuers will pay interest on the Notes on each February 14 and August 14 (each an “Interest Payment Date”), beginning on
February 14, 2020, to the Holders of record on the immediately preceding January 30 and July 30 (each a “Record Date”), respectively. 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 and including the date of issuance. Payments of the principal of and interest on the Notes shall be made in Dollars, and the Notes shall be denominated in Dollars. 

SECTION 2.06    Place of Payment. The place of payment where the Notes issued in the form of Definitive Notes may
be presented or surrendered for payment, where the principal of and interest and any other payments due on the Notes issued in the form of Definitive Notes are payable and where the Notes may be surrendered for registration of transfer or exchange
shall be the office or agency of the Issuers maintained for that purpose pursuant to Section 2.05 of the Original Indenture, and the office or agency maintained by the Issuers for such purpose shall initially be the Corporate Trust Office of
the Trustee. All payments on Notes issued in the form of Global Notes shall be made by wire transfer of immediately available funds to the Depositary and, at the option of the Issuers, payment of interest on the Notes issued in the form of
Definitive Notes may be made by check mailed to registered Holders. 
 SECTION 2.07    Form and Dating. 

(a)    General. The Notes will be substantially in the form of Exhibit A hereto. The terms and provisions contained
in the Notes will constitute, and are hereby expressly made, a part of this Twenty-First Supplemental Indenture and the Issuers and the Trustee, by their execution and delivery of this Twenty-First Supplemental Indenture, expressly agree to such
terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

  
 7 













 (b)    Global Notes. Notes issued in global form will be
substantially in the form of Exhibit A attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in
the form of Exhibit A attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding principal
amount of the Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of
outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Article III hereof. 

SECTION 2.08    [Reserved]. 

SECTION 2.09    Depositary; Registrar. The Issuers initially appoint DTC to act as Depositary with respect to the
Global Notes. The Issuers initially appoint the Trustee to act as the Registrar and the Paying Agent with respect to the Notes. 
 SECTION
2.10    Optional Redemption. 
 (a)    Prior to the Par Call Date, the Issuers may redeem all
or part of the Notes, after having sent a notice of redemption as described in Section 3.03 of the Original Indenture (except that, for the purposes of the Notes issued under this Twenty-First Supplemental Indenture, such notice shall be
required to be sent upon not less than 15 nor more than 45 days’ notice, rather than upon not less than 30 days nor more than 60 days’ notice), at a redemption price equal to the greater of (i) 100% of the principal amount of Notes and
(ii) the sum of the present value at such redemption date of all remaining scheduled payments of principal and interest on such Note through the Par Call Date (excluding accrued but unpaid interest to the redemption date), discounted to the
date of redemption using a discount rate equal to the Treasury Rate plus 25 basis points, plus, in each case, accrued and unpaid interest, if any, to, but not including, the redemption date, subject to the right of holders of record on the relevant
Record Date to receive interest due on the relevant Interest Payment Date. 
 (b)    On or after the Par Call Date, the
Notes may be redeemed at the Issuers’ option, at any time in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not
including, the redemption date, subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. 

SECTION 2.11    Redemption for Changes in Withholding Taxes. 

(a)    The Issuers are entitled to redeem the Notes, at the option of the Issuers, at any time in whole but not in part,
upon not less than 15 nor more than 45 days’ notice (which notice shall be irrevocable) to the Holders (with a copy to the Trustee) mailed by first-class mail 

  
 8 













 
to each Holder’s registered address (or delivered electronically if held by DTC), at 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including,
the date of redemption (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date) and Additional Amounts, if any, in the event the Issuers have become or would become
obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of: 

(i)    a change in or an amendment to the laws (including any regulations, rulings or protocols promulgated
and treaties enacted thereunder) of any Relevant Taxing Jurisdiction affecting taxation; or 

(ii)    any change in or amendment to, or the introduction of, any official position regarding the
application, administration or interpretation of such laws, regulations, rulings, protocols or treaties (including a holding, judgment or order by a court of competent jurisdiction), 

which change or amendment is announced or becomes effective on or after the date on which the Notes are issued (or, in the case of a jurisdiction that becomes
a Relevant Taxing Jurisdiction after such date, on or after such later date), and where the Issuers cannot avoid such obligation by taking reasonable measures available to the Issuers. Notwithstanding the foregoing, no such notice of redemption will
be given (x) earlier than 90 days prior to the earliest date on which the Issuers would be obliged to make such payment of Additional Amounts and (y) unless at the time such notice is given, such obligation to pay such Additional Amounts
remains in effect. 
 (b)    Before the Issuers publish or mail or deliver notice of redemption of the Notes as
described above, the Issuers will deliver to the Trustee an Officers’ Certificate stating that the Issuers cannot avoid their obligation to pay Additional Amounts by taking reasonable measures available to them and that all conditions precedent
to the redemption have been complied with. The Issuers will also deliver to the Trustee an Opinion of Counsel from outside counsel stating that the Issuers would be obligated to pay Additional Amounts as a result of a change or amendment described
above and that all conditions precedent to the redemption have been complied with. 
 (c)    This Section will apply
mutatis mutandis to any jurisdiction in which any successor Person to an Issuer is incorporated or organized or any political subdivision or taxing authority or agency thereof or therein.

and the Holders of a majority in principal amount of the Notes have requested the Issuers to issue Definitive Notes. 
 Upon the occurrence
of any of the preceding events in clause (a), (b) or (c) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Issuers and the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as
provided in Sections 2.09 and 2.11 of the Original Indenture. A Global Note may not be exchanged for a Definitive Note other than as provided in this Section 3.01; however, beneficial interests in a Global Note may be transferred and exchanged
as provided in Section 3.02 or 3.03 hereof. 
 SECTION 3.02    Transfer and Exchange of Beneficial Interests in
the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Twenty-First Supplemental Indenture and the Applicable Procedures. The
transferor of such beneficial interest must deliver to the Registrar either: 
 (a)    both: 

(A)    a written order from a Participant or an Indirect Participant given to the Depositary in accordance
with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

(B)    instructions given in accordance with the Applicable Procedures containing information regarding the
Participant account to be credited with such increase; or 
 (b)    both: 

(A)    a written order from a Participant or an Indirect Participant given to the Depositary in accordance
with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

(B)    instructions given by the Depositary to the Registrar containing information regarding the Person in
whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in subclause (A) of this clause (b). 

  
 10 













 Upon satisfaction of all of the requirements for transfer or exchange of beneficial
interests in Global Notes contained in this Indenture and the Notes, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 3.08 hereof. 

SECTION 3.03    Transfer or Exchange of Beneficial Interests in Global Notes for Definitive Notes. Subject to the
terms hereof, including Section 3.01 hereof, if any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery
thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 3.02 hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to
Section 3.08 hereof, and the Issuers will execute and the Trustee, upon receipt of a Company Order in accordance with Section 2.04 of the Original Indenture, will authenticate and deliver to the Person designated in the instructions a
Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 3.03 will be registered in such name or names and in such authorized denomination or denominations as
the Holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes
are so registered. 
 SECTION 3.04    Transfer and Exchange of Definitive Notes for Beneficial Interests in Global
Notes. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time.
Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes. 

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected at a time when a Global Note has not yet been
issued, the Issuers will issue and, upon receipt of a Company Order in accordance with Section 2.04 of the Original Indenture, the Trustee will authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount
of Definitive Notes so transferred. 
 SECTION 3.05    Transfer and Exchange of Definitive Notes for Definitive
Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.05, the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer
or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its
attorney, duly authorized in writing. 
 SECTION 3.06    [Reserved].

 SECTION 3.08    Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and
canceled by the Trustee in accordance with Section 2.12 of the Original Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such
other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

 COVENANTS 

SECTION 5.01    Repurchase upon a Change of Control Triggering Event. 

(a)    Upon the occurrence of a Change of Control Triggering Event after the date of this Twenty-First Supplemental
Indenture, the Issuers will make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest to, but not including, the date of purchase, subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date.

 (b)    Within 30 days following any Change of Control Triggering Event, the Issuers will send notice of such Change
of Control Offer by first-class mail, or delivered electronically if held by DTC, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the register or otherwise in accordance with the procedures of DTC, with
the following information: 
 (i)    a Change of Control Offer is being made pursuant to this
Section 5.01 and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment; 

(ii)    the purchase price and the purchase date, which will be no earlier than 30 days nor later than 60
days from the date such notice is mailed or delivered (the “Change of Control Payment Date”); 

  
 14 













 (iii)    any Note not properly tendered will remain
Outstanding and continue to accrue interest; 
 (iv)    unless the Issuers default 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, but not including, the Change of Control Payment Date; 

(v)    the instructions determined by the Issuers consistent with this covenant that a Holder must follow
in order to have its Notes purchased or to cancel a previous order of purchase; and 
 (vi)    if such
notice is mailed or delivered prior to the occurrence of a Change of Control Triggering Event, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control Triggering Event. 

(c)    While the Notes are in global form, when the Issuers make 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 DTC’s rules and regulations. 

(d)    If Holders of not less than 90% in aggregate principal amount of the Outstanding Notes validly tender and do not
withdraw such Notes in a Change of Control Offer and the Issuers, or any other Person making a Change of Control Offer in lieu of the Issuers as described below, purchase all of the Notes validly tendered and not withdrawn by such Holders, the
Issuers will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain Outstanding
following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the date of redemption (subject to the right of Holders of record on the relevant Record
Date to receive interest due on the relevant Interest Payment Date). 
 (e)    The Issuers will not be required to make
a Change of Control Offer following a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable
to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn pursuant to such Change of Control Offer or (2) notice of redemption has been given pursuant to this Indenture as described in
Section 3.03 of the Original Indenture (as amended and supplemented by this Twenty-First Supplemental Indenture), unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary
herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon the occurrence of such Change of Control Triggering Event. 

(f)    Notes repurchased by the Issuers pursuant to a Change of Control Offer will have the status of Notes issued but not
Outstanding or will be retired and canceled at the option of the Issuers. Notes purchased by a third party pursuant to the preceding paragraph will have the status of Notes issued and Outstanding. 

  
 15 













 (g)    The Issuers will comply with the requirements of
Section 14(e) under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer. To the
extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuers will comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations
described in this Indenture by virtue thereof. 
 (h)    On the Change of Control Payment Date, the Issuers (or any
Person making a Change of Control Offer in lieu of the Issuers) will, to the extent permitted by law, 

(i)    accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control
Offer; 
 (ii)    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

portions thereof have been tendered to and purchased by the Issuers. 
 (i)    The Paying Agent will promptly mail or
otherwise deliver to each Holder of the Notes the Change of Control Payment for such Notes, and the Issuers shall execute and the Trustee, upon a Company Order, will promptly authenticate and mail, or will cause to be delivered electronically if
held by DTC, 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 denomination of $150,000 and an integral multiple of $1,000
above that amount. The Issuers will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 of the Original Indenture and ending at the close of business on the day of selection; (b) to register the transfer of
or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or (c) to register the transfer of or to exchange a Note between a Record Date and the next succeeding
Interest Payment Date. 
  

	10.	 Further Issues 



The Issuers may from time to time, without the consent of the Holders of the Notes and in accordance with the Indenture, create and issue
further notes having the same terms and conditions as the Notes in all respects (or in all respects except for the issue date and the amount and the date of the first payment of interest) so as to form a single Series with the Notes. 

 

	11.	 Optional Redemption 



(a)    Prior to the Par Call Date, the Issuers may redeem all or part of the Notes, after having sent a notice of
redemption as described in Section 3.03 of the Original Indenture (except that, for the purposes of the Notes issued under the Twenty-First Supplemental Indenture, such notice shall be required to be sent upon not less than 15 nor more than 45
days’ notice, rather than upon not less than 30 nor more than 60 days’ notice), at a redemption price equal to the greater of (i) 100% of the principal amount of Notes or (ii) the sum of the present value at such redemption date of
all remaining scheduled payments of principal and interest on such Note through the Par Call Date (excluding accrued but unpaid interest to the redemption date), discounted to the date of redemption using a discount rate equal to the Treasury Rate
plus 25 basis points, plus, in each case, accrued and unpaid interest, if any, to, but not including, the redemption date, subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment
Date. 
 (b)    On or after the Par Call Date, the Notes may be redeemed at the Issuers’ option, at any time in
whole or from time to time in part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not including, the redemption date, subject to the right of holders of
record on the relevant Record Date to receive interest due on the relevant Interest Payment Date.

	12.	 Redemption for Changes in Withholding Taxes 



(a)    The Issuers are entitled to redeem the Notes, at the option of the Issuers, at any time in whole but not in part,
upon not less than 15 nor more than 45 days’ notice (which notice shall be irrevocable) to the Holders (with a copy to the Trustee) mailed by first-class mail to each Holder’s registered address (or delivered electronically if held by
DTC), at 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant
Interest Payment Date) and Additional Amounts, if any, in the event the Issuers have become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of:

 (i)    a change in or an amendment to the laws (including any regulations, rulings or protocols
promulgated and treaties enacted thereunder) of any Relevant Taxing Jurisdiction affecting taxation; or 

(ii)    any change in or amendment to, or the introduction of, any official position regarding the
application, administration or interpretation of such laws, regulations, rulings, protocols or treaties (including a holding, judgment or order by a court of competent jurisdiction), 

which change or amendment is announced or becomes effective on or after the date on which the Notes are issued (or, in the case of a jurisdiction that becomes
a Relevant Taxing Jurisdiction after such date, on or after such later date), and where the Issuers cannot avoid such obligation by taking reasonable measures available to the Issuers. Notwithstanding the foregoing, no such notice of redemption will
be given (x) earlier than 90 days prior to the earliest date on which the Issuers would be obliged to make such payment of Additional Amounts and (y) unless at the time such notice is given, such obligation to pay such Additional Amounts
remains in effect. 
 (b)    Before the Issuers publish or mail or deliver notice of redemption of the Notes as
described above, the Issuers will deliver to the Trustee an Officers’ Certificate stating that the Issuers cannot avoid their obligation to pay Additional Amounts by taking reasonable measures available to them and that all conditions precedent
to the redemption have been complied with. The Issuers will also deliver to the Trustee an Opinion of Counsel from outside counsel stating that the Issuers would be obligated to pay Additional Amounts as a result of a change or amendment described
above and that all conditions precedent to the redemption have been complied with. 
 (c)    This Section will apply
mutatis mutandis to any jurisdiction in which any successor Person to an Issuer is incorporated or organized or any political subdivision or taxing authority or agency thereof or therein. 

 

	13.	 Persons Deemed Owners 



The ownership of Notes shall be proved by the register maintained by the Registrar. 

  
 A-7 














	14.	 No Recourse Against Others 



No director, officer, employee, incorporator or stockholder of the Issuers, as such, will have any liability for any obligations of the Issuers
under the Notes, 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. The waiver may not be effective to waive liabilities under the federal securities laws. 
  

	15.	 Discharge and Defeasance 



Subject to certain conditions set forth in the Indenture, the Issuers at any time may terminate some or all of their obligations under the
Notes and the Indenture if the Issuers deposit with the Trustee money and/or U.S. Government Obligations for the payment of principal of, premium, if any, and interest on the Notes to redemption or maturity, as the case may be. 

 

	16.	 Unclaimed Money 



Any money deposited with the Trustee or any Paying Agent, or then held by an Issuer, in trust for the payment of the principal of, premium, if
any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Issuers on their request or, if then held by an Issuer, shall be discharged
from such trust. Thereafter the Holder of such Note shall look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Issuers. 
  

	17.	 Trustee Dealings with the Issuers 



Subject to certain limitations imposed by the TIA, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar or co paying agent may do the same with like rights. 

 

	18.	 Abbreviations 



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

  
 A-8 














	19.	 CUSIP Numbers 



Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers
to be printed on the Notes and have directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  

	20.	 Governing Law 



THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT
TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
 The
Issuers will furnish to any Holder of Notes upon written request and without charge to the Holder a copy of the Indenture.
