Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes of the series being reopened for
U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes of the series being reopened. 

 

	202.	 Principal Amount of the Notes; Maturity

	203.	 Form of Notes; Denominations; Depositary 

(a) On the date hereof, the Company shall execute and the Trustee shall authenticate and deliver initial Securities (together with any
Additional Notes of such series, if any, issued in a transaction exempt from the registration requirements of the Securities Act, the “Initial Notes”) in the form of Global Notes (as defined below) of each applicable series. The 7.875%
2026 Notes shall be initially issued in the form of one or more Global Securities (the “7.875% 2026 Global Notes”) in substantially the form set forth in Exhibit A hereto. The 7.750% 2026 Notes shall be initially issued in the form
of one or more Global Securities (the “7.750% 2026 Global Notes”) in substantially the form set forth in Exhibit B hereto. The 2028 Notes shall be initially issued in the form of one or more Global Securities (the “2028 Global

The 2036 Notes shall be initially issued in the form of one or more Global Securities (the “2036 Global Notes” and, together with the 7.875% 2026 Global Notes, the 7.750% 2026 Global Notes, the 2028 Global Notes, the 2029 Global Notes and
the 2031 Global Notes, the “Global Notes”) in substantially the form set forth in Exhibit F hereto. The Notes shall be issued in fully registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. 
 (b) The initial Depositary in respect of the Global Notes shall be The Depository Trust Company. The Global Notes shall
be deposited with, or on behalf of, the Depositary and shall be registered in the name of Cede & Co. Except as otherwise set forth in herein or Section 305 of the Original Indenture, the Global Notes may be transferred, in whole or in
part, only to the Depositary, another nominee of the Depositary or to a successor of the Depositary or its nominee. 
 (c) The Initial Notes
being issued on the date hereof are being issued by the Company only to (i) persons reasonably believed to be “qualified institutional buyers” (“QIBs”) (as defined in Rule 144A (“Rule 144A”) under the Securities
Act of 1933, as amended (the “Securities Act”)) and (ii) persons other than U.S. Persons (as defined in Regulation S) outside the United States in offshore transactions in reliance on Regulation S (“Regulation S”) under the
Securities Act. Initial Notes of each series that are offered in reliance on Rule 144A shall be issued in the form of one or more permanent Global Notes substantially in the form of the applicable form of Note attached hereto (each, a “QIB
Global Note”) bearing the Restricted Notes Legend (as defined below) and the Global Note legend in the first paragraph of the face of the forms of Note attached hereto (the “Global Notes Legend”). Initial Notes of each series that are
offered in offshore transactions in reliance on Regulation S shall be issued in the form of one or more permanent Global Notes substantially in the form of the applicable form of Note attached hereto (each, a “Regulation S Global Note”)
bearing the Restricted Notes Legend, the Global Notes Legend, and the legends in the fourth, fifth and sixth paragraphs of the face of each Regulation S Global Note. The QIB Global Note and the Regulation S Global Note with respect to each series of
Notes shall be issued with separate CUSIP numbers. The aggregate principal amount of each Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as Security Registrar. Transfers of Notes of an
applicable series between QIBs and to or by purchasers pursuant to Regulation S shall be represented by appropriate increases or decreases to the respective amounts of the appropriate Global Notes, as more fully provided in paragraph (d) below.

 (d) Restricted Notes Legend. Unless and until (i) a restricted note, as defined in Rule 144(a)(3) under the Securities Act (a
“Restricted Note”), is exchanged for an Exchange Note (as defined below) or sold in connection with an effective shelf registration statement or (ii) the Company determines and there is delivered to the Trustee an Opinion of Counsel
and an Officers’ Certificate to the effect that the legend in the second and third paragraphs of the face of the forms of Note attached hereto (the “Restricted Notes Legend”), and the related restrictions on transfer are not required
in order to maintain compliance with the provisions of the Securities Act, each Global Note and each definitive Security (and all Notes issued in exchange therefor or substitution therefor) shall bear the applicable Restricted Notes Legend. 

  
 6 

 (e) Special Transfer Provisions. Unless and until (i) a Restricted Note is
exchanged for an Exchange Note or sold in connection with an effective registration statement or (ii) the Restricted Notes Legend is no longer required pursuant to paragraph (d) above, the following provisions shall apply: 

(i) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of
beneficial interests in a Restricted Note (other than pursuant to Regulation S): 
  

	 	(A)	 The Security Registrar shall register the transfer of a beneficial interest in a Restricted Note by a Holder
that is not a Depositary to a QIB if such transfer is being made by a proposed transferor who has provided the Security Registrar with (1) an appropriately completed assignment form and (2) a signed representation, in each case in the form
of the same attached to the applicable Note. 

  

	 	(B)	 If the proposed transferee is a member of, or participant in, the Depositary (an “Agent Member”) and
the beneficial interest in a Restricted Note to be transferred consists of an interest in a Regulation S Global Note, upon receipt by the Security Registrar of (1) the items required by paragraph (A) above and (2) instructions given
in accordance with the Depositary’s and the Security Registrar’s procedures therefor, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the applicable QIB Global Note in an
amount equal to the principal amount of the beneficial interest in the Regulation S Global Note to be so transferred, and the Security Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of
such Regulation S Global Note. 

 (ii) Transfers Pursuant to Regulation S. The following provisions
shall apply with respect to the registration of any proposed transfer of a beneficial interest in a Restricted Note pursuant to Regulation S: 
  

	 	(A)	 The Security Registrar shall register any proposed transfer of a beneficial interest in a Restricted Note
pursuant to Regulation S by a Holder upon receipt of (1) an appropriately completed assignment form and (2) a signed representation, in each case in the form of the same attached to the applicable Note. 

 

	 	(B)	 If the proposed transferee is an Agent Member and the beneficial interest in a Restricted Note to be
transferred consists of an interest in a QIB Global Note, upon receipt by the Security Registrar of (1) the items required by paragraph (A) above and (2) instructions in accordance with the Depositary’s and the Security
Registrar’s procedures therefor, the Security Registrar shall reflect on its 

  
 7 

	 	
books and records the date and an increase in the principal amount of the applicable Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the QIB
Global Note to be transferred, and the Security Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of such QIB Global Note. 

(iii) Exchange Offer. Upon the occurrence of an offer made by the Company to exchange (each, an “Exchange
Offer”) Initial Notes or Additional Notes, if any, of a series bearing the Restricted Notes Legend for exchange notes which will be registered under the Securities Act and have terms identical in all material respects to such Initial Notes or
such Additional Notes, as the case may be (the “Exchange Notes”), including the Exchange Offers contemplated by a Registration Rights Agreement, the Company shall execute a Company Order in accordance with Section 303 of the Original
Indenture with respect to each applicable series of Notes, and the Trustee shall authenticate, one or more Global Notes not bearing the Restricted Notes Legend in an aggregate principal amount equal to the principal amount of the beneficial
interests in the Global Notes of each applicable series that are Restricted Notes tendered for acceptance in accordance with the applicable Exchange Offer and accepted for exchange in such Exchange Offer. Concurrently with the issuance of such
Global Notes, the Security Registrar shall cause the aggregate principal amount of the applicable Restricted Notes to be reduced accordingly, and the Security Registrar shall cause to be delivered to the Persons designated by the Holders of such
Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate principal amount. 

(iv) Restricted Notes Legend. Upon the transfer, exchange or replacement of one or more Notes that do not and are not
required to bear the Restricted Notes Legend (“Unrestricted Notes”), the Security Registrar shall deliver Unrestricted Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Restricted Notes of
any series, other than in exchange for Exchange Notes pursuant to an Exchange Offer, the Security Registrar shall cause to be delivered only Restricted Notes that bear the Restricted Notes Legend unless the Restricted Notes Legend is no longer
required by paragraph (d) above and there is delivered to the Trustee an Opinion of Counsel and an Officers’ Certificate of the Company, each to the effect that neither such legend nor the related restrictions on transfer are required in
order to ensure that subsequent transfers of such Notes are effected in compliance with the Securities Act. Upon receipt of such Opinion of Counsel and Officers’ Certificate of the Company, the Trustee shall direct the Security Registrar to
exchange the applicable Restricted Notes for Unrestricted Notes of such series with such exchange to occur in accordance with paragraph (v) below (in the case of Global Notes). 

(v) Acknowledgement of Transfer Restrictions. By its acceptance of any Note bearing the Restricted Notes Legend, each
Holder of such a Note acknowledges receipt of a Restricted Note with the restrictions on transfer of such Note set forth in this Tenth Supplemental Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as
provided in this Tenth Supplemental Indenture until such time as the Restricted Notes Legend is no longer required pursuant to paragraph (d) above and 

  
 8 

 
such Holder transfers such a Restricted Note to an Unrestricted Note. The Security Registrar shall not register a transfer of any Note unless such transfer complies with the restrictions on
transfer of such Note set forth in this Tenth Supplemental Indenture. In connection with any transfer of Notes, each Holder agrees by its acceptance of the Notes to furnish the Trustee, the Security Registrar or the Company such certifications,
legal opinions or other information as any of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act until such time
as the Restricted Notes Legend is no longer required pursuant to paragraph (d) above and such Holder transfers such a Restricted Note to an Unrestricted Note; provided that the Security Registrar shall not be required to determine (but may rely
on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information. 

The Security Registrar shall retain copies of all letters, notices and other written communications received pursuant to this paragraph
(e) in accordance with its customary procedures. 
 None of the Trustee, the Security Registrar or any agent thereof shall have any
obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture, this Tenth Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note
(including any transfers between or among Agent Members or beneficial owners of interests in any Global Notes) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and
when expressly required by the terms of, the Indenture or this Tenth Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements thereof or hereof. 

 

	204.	 Payment 

The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time
of payment is legal tender for payment of public and private debts. The Company will make all payments of interest on any Global Note in accordance with the arrangements then existing between the Paying Agent and the applicable Depositary, and all
payments of principal of and premium, if any, on any Global Note at the Corporate Trust Office upon surrender of such Note for payment. The Company will make all payments of interest on any definitive Note by mailing a check to the address of each
Person entitled thereto, and all payments of principal of and premium, if any, on any definitive Note at the Corporate Trust Office upon surrender of such Note for payment. 

If any Additional Interest will be due pursuant to the terms of the Registration Rights Agreement in respect of a series of Notes, prior to
the time such Additional Interest is payable, the Company shall deliver an Officers’ Certificate to the Trustee and Paying Agent setting forth the Additional Interest per $1,000 aggregate principal amount of such Notes and the date from which
such Additional Interest shall accrue. The Company shall also deliver an Officers’ Certificate to the Trustee and the Paying Agent setting forth the date after which such Additional Interest shall cease accruing. Neither the Trustee nor the
Paying Agent shall have any 

  
 9 

 
responsibility or liability for the determination, verification or calculation of any Additional Interest. All references to any amount of “interest payable” on or with respect to a
Note of a series in the Indenture shall be deemed to include any applicable Additional Interest that may be payable on or with respect to such Note.

value received, hereby promises to pay to [________________]5 [CEDE & CO.]6, or registered assigns, the principal sum of
________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on March 1, 2026 (the “Maturity Date”), and to pay interest thereon from September 1, 2021 (the “Original
Accrual Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 1 and September 1 in each year (each an
“Interest Payment Date”), commencing March 1, 2022, at the rate of 7.875% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a

(“Additional Interest”) shall accrue on this Note if and to the extent provided for in accordance with the terms of the Registration Rights Agreement]7. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note
(the “Predecessor Notes”)) is registered at the close of business on the February 15 or August 15 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next preceding such
Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the Holder 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 under the Indenture, notice whereof shall be given to Holders of Notes
not less than 10 days prior to such Special Record Date, or 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 said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding
Interest Payment Date (or from and including the Original Accrual Date, in the case of

the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day
that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the
Maturity Date, as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this
Note.]

America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the
Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for payment.]8 [The Company will make all
payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of principal of and premium, if any, on this Note at the Corporate Trust Office upon surrender of this Note for payment.]9 
 Reference is hereby made to the further provisions of this Note set forth on the
reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 
 Unless the
certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual or electronic signature, this Note shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental
Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental
Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture,
the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for
a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “7.875% Senior Notes due 2026” of the Company initially limited in aggregate
principal amount to $76,490,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

them by the Indenture.

7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of
transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges
pursuant to Section 304, 906 or 1107 not involving any transfer. 
 8. Persons Deemed Owner. The Holder of this Note may be treated as the owner
of this Note for all purposes. 
 9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not
to the Trustee or any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth
in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture. 
 11. Amendment;
Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions
permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of
the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to

value received, hereby promises to pay to [________________]14 [CEDE & CO.]15, or registered assigns, the principal sum of
________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on March 15, 2026 (the “Maturity Date”), and to pay interest thereon from March 15, 2021 (the “Original Accrual
Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 15 and September 15 in each year (each an

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 said
Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the

Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a

 3. Paying Agent
and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration
of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental
Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental
Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture,
the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for
a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “7.750% Senior Notes due 2026” of the Company initially limited in aggregate
principal amount to $47,828,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to
them by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at
the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60
days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present
values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate
(as defined below), as determined by the Independent Investment Banker (as defined below), plus 10 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including,
the Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates
falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the
Tenth Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the “Independent Investment Banker.” 
 “Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP
Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided,
however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

  

					
		 	B-8	 	Reverse Side of Form of 7.750% Senior Note due 2026

 “Reference Treasury Dealer Quotation” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date. 
 The Company
shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for
redemption by the Depositary in accordance with its standard procedures therefor. 
 6. Sinking Fund. The Notes are not subject to any sinking fund
or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall
be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or
exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during
the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note
so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part). 
 8. Persons Deemed Owner. The

Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has
been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note
for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter 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 times, place and rate, and in the coin or currency, herein prescribed. 

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any
claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of
any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the
issue hereof, expressly waived and released.

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or
not, except as provided in Section 802 of the Original Indenture.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Interest Payment Date (or from and including the Original Accrual Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or

 3. Paying Agent
and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration
of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental
Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental
Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture,
the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for
a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “6.650% Senior Notes due 2028” of the Company initially limited in aggregate
principal amount to $38,859,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to
them by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at
the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60
days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present
values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate
(as defined below), as determined by the Independent Investment Banker (as defined below), plus 12.5 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including,
the Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates
falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the
Tenth Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the “Independent Investment Banker.”

Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as
Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has

claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of
any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the
issue hereof, expressly waived and released.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental
Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental
Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture,
the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for
a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “7.750% Senior Notes due 2029” of the Company initially limited in aggregate
principal amount to $79,323,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

them by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at
the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60
days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present
values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate
(as defined below), as determined by the Independent Investment Banker (as defined below), plus 25 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including,
the Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates
falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the
Tenth Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the “Independent Investment Banker.” 
 “Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP
Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided,
however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

 “Reference Treasury Dealer Quotation” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date. 
 The Company
shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation.

or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall
be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or
exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during
the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note
so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part). 
 8. Persons Deemed Owner. The
Holder of this Note may be treated as the owner of this Note for all purposes. 
 9. Unclaimed Funds. If money for the payment of principal, premium
or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled
to the money must look only to the Company and not to the Trustee or any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be
subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as

for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation

any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the
issue hereof, expressly waived and released.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding
Interest Payment Date (or from and including the Original Accrual Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest

Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. [All references to any amount of
“interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

principal amount to $166,864,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to
them by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at
the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60
days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present
values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate
(as defined below), as determined by the Independent Investment Banker (as defined below), plus 30 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including,
the Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates
falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the
Tenth Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the “Independent Investment Banker.” 
 “Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP
Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided,
however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

  

					
		 	E-8	 	Reverse Side of Form of 7.750% Senior Note due 2031

 “Reference Treasury Dealer Quotation” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date. 
 The Company
shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for
redemption by the Depositary in accordance with its standard procedures therefor. 
 6. Sinking Fund. The Notes are not subject to any sinking fund
or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall
be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or
exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during
the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note
so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part). 
 8. Persons Deemed Owner. The
Holder of this Note may be treated as the owner of this Note for all purposes. 
 9. Unclaimed Funds. If money for the payment of principal, premium
or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled
to the money must look only to the Company and not to the Trustee or any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be
subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each

or not notation of such consent or waiver is made upon this Note. 
 12. Defaults and Remedies. If an Event of Default with respect to the Notes
shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not
have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as
Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has
been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note
for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter 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 times, place and rate, and in the coin or currency, herein prescribed. 

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any
claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of
any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the
issue hereof, expressly waived and released.

Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

not, except as provided in Section 802 of the Original Indenture.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

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. 

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

 1. Principal and
Interest. NORTHROP GRUMMAN CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to [________________]50 [CEDE & CO.]51, or registered assigns, the principal sum of
________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on March 15, 2036 (the “Maturity Date”), and to pay interest thereon from March 15, 2021 (the “Original Accrual
Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 15 and September 15 in each year (each an
“Interest Payment Date”), commencing September 15, 2021, at the rate of 6.980% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a

the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or
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 said
Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the
Original Accrual Date, in the case of the initial Interest

Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a
Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date,
as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

6.980% Senior Note due 2036 
 3. Paying Agent
and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration
of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental
Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental
Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture,
the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for
a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “6.980% Senior Notes due 2036” of the Company initially limited in aggregate
principal amount to $12,300,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”).
Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date
and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to
them by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at
the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60
days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present
values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate
(as defined below), as determined by the Independent Investment Banker (as defined below), plus 10 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including,
the Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates
falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the
Tenth Supplemental Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining
term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as
the “Independent Investment Banker.” 
 “Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP
Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided,
however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

  

					
		 	F-8	 	Reverse Side of Form of 6.980% Senior Note due 2036

 “Reference Treasury Dealer Quotation” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date. 
 The Company
shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for
redemption by the Depositary in accordance with its standard procedures therefor. 
 6. Sinking Fund. The Notes are not subject to any sinking fund
or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall
be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or
exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during
the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note
so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part). 
 8. Persons Deemed Owner. The
Holder of this Note may be treated as the owner of this Note for all purposes. 
 9. Unclaimed Funds. If money for the payment of principal, premium
or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled
to the money must look only to the Company and not to the Trustee or any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be
subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each
series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Note. 
 12. Defaults and Remedies. If an Event of Default with respect to the Notes
shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not
have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as
Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has
been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note
for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter 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 times, place and rate, and in the coin or currency, herein prescribed. 

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any
claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of
any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the
issue hereof, expressly waived and released.

Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or
not, except as provided in Section 802 of the Original Indenture.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

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.

Offer. The Exchange Offer shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Registrable Securities and to permit resales of Initial Securities held by Broker-Dealers as contemplated
by Section 3(c) hereof. 
 (b) The Company shall use its commercially reasonable efforts to cause the Exchange Offer Registration
Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however,
that in no event shall such period be less than 20 business days after the date notice of the Exchange Offer is first published or delivered to the Holders. The Company shall cause the Exchange Offer to comply with all applicable federal and state
securities laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. The Company shall use its commercially reasonable efforts to cause the Exchange Offer to be Consummated on the earliest
practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 365 days after the Closing Date (or if such 365th day is not a Business Day, the next succeeding Business Day). 

(c) The Company shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer
Registration Statement that any Broker-Dealer who holds Initial Securities that are Registrable Securities and that were acquired for its own account as a result of market-making activities or other trading activities (other than Registrable
Securities acquired directly from the Company), may exchange such Initial Securities pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within 

  
 -4- 

 
the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities received by
such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution”
section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such
Broker-Dealer or disclose the amount of Initial Securities held by any such Broker-Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement. 

The Company shall use its commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective,
supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities acquired by Broker-Dealers for their own accounts as a result of
market-making activities or other trading activities, and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period
ending on the earlier of (i) 90 days from the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with
market-making or other trading activities. 
 The Company shall provide sufficient copies of the latest version of such Prospectus contained
in such Exchange Offer Registration Statement to Broker-Dealers promptly upon request at any time during such 90-day (or shorter as provided in the foregoing sentence) period in order to facilitate such
resales. 
 SECTION 4. Shelf Registration. 

(a) Shelf Registration. If (i) the Company is not required to file an Exchange Offer Registration Statement or to consummate the
Exchange Offer because the Company determines that the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), (ii) for any reason the Exchange
Offer is not Consummated within 365 days after the Closing Date (or if such 365th day is not a Business Day, the next succeeding Business Day), or (iii) with respect to any Holder of Registrable Securities such Holder notifies the Company in
writing prior to the 20th calendar day following Consummation of the Exchange Offer that (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer or (B) such Holder may not resell the
Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, then,
upon such Holder’s request, the Company shall use its commercially reasonable efforts to cause a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement
(in either event, the “Shelf Registration Statement”) to be filed and declared effective by the Commission on or prior to the 

  
 -5- 

 
earliest to occur of (1) the 90th day after the date on which the Company determines that it is not required to file the Exchange Offer Registration Statement, and (2) the 90th day
after the date on which the Company receives notice from a Holder of Registrable Securities as contemplated by clause (iii) above, (such earliest date being the “Shelf Filing Deadline”) which Shelf Registration Statement shall
provide for resales of all Registrable Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof. Notwithstanding the foregoing, in no event shall the Company be required to file a Shelf
Registration Statement (and no Shelf Filing Deadline shall occur) prior to 365 days after the Closing Date (or if such 365th day is not a Business Day, the next succeeding Business Day). 

The Company shall use its commercially reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and
amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities by the Holders of Registrable Securities who shall have provided the information
required pursuant to Section 4(b) hereof and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, until all the Initial
Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or are freely tradeable pursuant to Rule 144(k) of the Securities Act. 

Notwithstanding anything to the contrary in this Agreement, at any time, the Company may delay the filing of any Shelf Registration Statement
or delay or suspend the effectiveness thereof, for a reasonable period of time, but not in excess of 120 days in the aggregate during any 12-month period (each, a “Shelf Suspension Period”),
if the Company reasonably determines that the filing of any such Shelf Registration Statement or the continuing effectiveness thereof would require the disclosure of non-public material information that, in
the reasonable judgment of the Company, would be detrimental to the Company if so disclosed or would otherwise materially adversely affect a financing, acquisition, disposition, merger or other material transaction or such action is required by
applicable law; provided that in no event shall the Company be required to disclose the business purpose for such suspension. Any Shelf Suspension Period pursuant to this Section 4(a) shall begin on the date specified in a written notice
given by the Company to the Holders and shall end on the date specified in a subsequent written notice given by the Company to the Holders. 

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Registrable
Securities may include any of its Registrable Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 20 Business Days after receipt of a request therefor,
such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder as to which any Shelf Registration Statement is being effected
agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading. 

  
 -6- 

 SECTION 5. Additional Interest. If, with respect to a series of Registrable
Securities, (i) the Exchange Offer for such series has not been Consummated within 365 days after the Closing Date (or if such 365th day is not a Business Day, the next succeeding Business Day) or (ii) any Shelf Registration Statement for
such series required by this Agreement is not filed prior to the applicable Shelf Filing Deadline or filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose for a period of time (expect
as specifically permitted herein, including with respect to any Shelf Suspension Period as provided in Section 4(a) hereof or because of the sale of all Registrable Securities under such Shelf Registration Statement) without being succeeded
immediately by a post-effective amendment to such Shelf Registration Statement that cures such failure and that is itself immediately declared effective (each such event referred to in clauses (i) and (ii), a “Registration
Default”), the Company hereby agrees that the interest rate borne by the Registrable Securities of such series shall be increased by 0.25% per annum immediately following the occurrence of any Registration Default (such interest,
“Additional Interest”); provided that Additional Interest shall accrue from and including the date that the applicable Registration Default occurs and is continuing to but excluding the date that is the earlier of
(x) the date on which such Registration Default is cured and (y) the date on which the Initial Securities of the applicable series cease to be Registrable Securities. Notwithstanding the foregoing, the amount of Additional Interest borne
by any series of Initial Securities as a result of a Registration Default shall in no event exceed 0.25% per annum even if more than one Registration Default has occurred and is continuing. Following the cure of all Registration Defaults relating to
any particular series of Registrable Securities or such applicable Initial Securities ceasing to be Registrable Securities, the interest rate borne by the relevant Registrable Securities will be reduced to the original interest rate borne by such
Initial Securities; provided, however, that, if after any such reduction in interest rate, a different Registration Default with respect to such series of Registrable Securities occurs, the interest rate borne by the relevant Registrable
Securities shall again be increased pursuant to the foregoing provisions. Additional Interest shall not be payable with respect to Registration Defaults for any period during which a Shelf Registration Statement is effective and usable by the
Holders of Registrable Securities of such series. 
 Notwithstanding the foregoing, the Company shall not be required to pay Additional
Interest with respect to the Registrable Securities to any Holder if the failure arises from the Company’s failure to file, or cause to become effective, a Shelf Registration Statement within the time periods specified in Section 4 by
reason of the failure of such Holder to provide such information as (i) the Company may reasonably request, with reasonable prior written notice, for use in the Shelf Registration Statement or any Prospectus included therein to the extent the
Company reasonably determines that such information is required to be included therein by applicable law, (ii) FINRA or the SEC may request in connection with such Shelf Registration Statement or (iii) is required to comply with the
agreements of such Holder as contained herein to the extent compliance thereof is necessary for the Shelf Registration Statement to be declared or otherwise become effective, including, without limitation, a signed notice and questionnaire as
distributed by the Company consenting to such Holder’s inclusion in the Prospectus as a selling security holder, evidencing such Holder’s agreement to be bound by the applicable provisions of this Agreement and providing such further
information to the Company as the Company may reasonably request. 
 For the avoidance of doubt, a Registration Default or a default or
event of default under this Agreement shall not constitute a default or event of default under the Indenture. 

  
 -7- 

 SECTION 6. Registration Procedures. 

(a) Representation of Holders. As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each
Holder of Registrable Securities shall furnish, upon the request of the Company, prior to the Consummation thereof, a written representation to the Company (which may be contained in the letter of transmittal contemplated by the Exchange Offer
Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution of
the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Registrable Securities shall otherwise use commercially reasonable
efforts to cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be
acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital
Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters, and (2) must
comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement
containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for Initial
Securities acquired by such Holder directly from the Company. 
 (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall comply with all the provisions of Section 6(c) hereof and shall use its commercially reasonable efforts to effect such registration to permit the sale of the Registrable Securities being sold in
accordance with the intended method or methods of distribution thereof, and pursuant thereto the Company will as expeditiously as reasonably possible prepare and file with the Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the sale of the Registrable Securities in accordance with the intended method or methods of distribution thereof. 

(c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the sale
or resale of Registrable Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial Securities by Broker-Dealers), the Company shall: 

  
 -8- 

 (i) except as otherwise permitted by this Agreement, use its commercially
reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements for the period specified in Section 3 or 4 hereof, as applicable; upon the occurrence of any event that would cause any
such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Registrable Securities during the period required by this Agreement, the
Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its commercially reasonable efforts
to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as practicable thereafter; 

(ii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration
Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Registrable Securities covered by such
Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable
provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period
in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; 

(iii) in the case of a Shelf Registration Statement, advise selling Holders promptly and, if requested by such Persons, to
confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to any Shelf Registration Statement or any post-effective amendment thereto, when the same has
become effective, (B) of any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission
of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Securities for offering or sale in any
jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Shelf Registration Statement, the
Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the
statements therein not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order
suspending the qualification or exemption from qualification of the Registrable Securities under state securities or blue sky laws, the Company shall use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the
earliest possible time; 

  
 -9- 

 (iv) in the case of a Shelf Registration Statement, furnish without charge,
upon request, to each selling Holder named in any Shelf Registration Statement and to counsel for the Dealer Managers, at least two Business Days before filing with the Commission, copies of any Shelf Registration Statement or any Prospectus
included therein or any amendments or supplements to any such Shelf Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Shelf Registration Statement); 

(v) [reserved]; 

(vi) [reserved]; 

(vii) if requested by any selling Holders, promptly incorporate in any Shelf Registration Statement or Prospectus, pursuant to
a supplement or post-effective amendment if necessary, such information as such selling Holders may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the
Registrable Securities, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as
soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 

(viii) [reserved]; 

(ix) furnish to each selling Holder, upon request, without charge, at least one copy of the Shelf Registration Statement, as
first filed with the Commission, and of each amendment thereto, including financial statements and schedules, all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference) if such documents
are not available via EDGAR; 
 (x) deliver to each selling Holder, without charge, as many copies of the Prospectus
(including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; the Company hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders
in connection with the offering and the sale of the Registrable Securities covered by the Prospectus or any amendment or supplement thereto if such documents are not available via EDGAR; 

(xi) enter into such agreements, and make such representations and warranties, and take all such other actions in connection
therewith in order to expedite or facilitate the disposition of the Registrable Securities pursuant to any Shelf Registration Statement contemplated by this Agreement, all to such extent as may be reasonably requested by any Holder of Registrable
Securities and only as are customarily entered into, made or taken in similar circumstances in connection with any sale or resale pursuant to any Shelf Registration Statement contemplated by this Agreement; and the Company shall: 

  
 -10- 

 (A) furnish to each selling Holder in such substance and scope as they may
reasonably request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the date of the effectiveness of the Shelf Registration Statement: 

(1) a certificate, dated the date of effectiveness of the Shelf Registration Statement, signed by the Chief Financial Officer
or Treasurer of the Company, confirming, as of the date thereof, the matters set forth in paragraphs (i), (ii) and (iii) of Section 6(l) of the Dealer Manager Agreement and such other matters as such parties may reasonably request; 

(2) a customary opinion, dated the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel
for the Company, covering the matters set forth in Section 6(d) of the Dealer Manager Agreement and such other matter as such parties may reasonably request; and 

(3) a customary comfort letter, dated the date of effectiveness of the Shelf Registration Statement, from the Company’s
independent accountants, in the customary form and covering matters of the type customarily requested to be covered in comfort letters by underwriters in connection with primary underwritten offerings, and covering or affirming the matters set forth
in the comfort letters delivered pursuant to Section 6(i) of the Dealer Manager Agreement, without exception; 
 (B) set
forth in full or incorporate by reference in the underwriting agreement, if any, the indemnification provisions and procedures of Section 8 hereof with respect to all parties to be indemnified pursuant to said Section; and 

(C) deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with
Section 6(c)(xi)(A) hereof and with any customary conditions contained in any agreement entered into by the Company pursuant to this Section 6(c)(xi), if any. 

If at any time the representations and warranties of the Company contemplated in Section 6(c)(xi)(A)(1) hereof cease to be
true and correct, the Company shall so advise each selling Holder promptly and, if requested by such Persons, shall confirm such advice in writing; 

  
 -11- 

 (xii) prior to any public offering of Registrable Securities, use
commercially reasonable efforts to cooperate with the selling Holders and their respective counsel in connection with the registration and qualification of the Registrable Securities under the state securities or blue sky laws of such jurisdictions
as the selling Holders may reasonably request and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the Shelf Registration Statement;
provided, however, that the Company shall not be required to (A) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (B) file
any general consent to service of process in any such jurisdiction, (C) subject itself to taxation or tariff in any such jurisdiction if it is not so subject or (D) make any change to its charter or
by-laws or similar organizational documents; 
 (xiii) issue, upon the request of any
Holder of Initial Securities covered by the Shelf Registration Statement, Exchange Securities having an aggregate principal amount equal to the aggregate principal amount of Initial Securities surrendered to the Company by such Holder in exchange
therefor or being sold by such Holder; such Exchange Securities to be registered in the name of such Holder or in the name of the purchaser(s) of such Securities, as the case may be; in return, the Initial Securities held by such Holder shall be
surrendered to the Company for cancellation; 
 (xiv) use commercially reasonable efforts to cooperate with the selling
Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends; and enable such Registrable Securities to be in such denominations and registered in
such names as the Holders may request at least two Business Days prior to any sale of Registrable Securities made by such Holders; 

(xv) [reserved]; 

(xvi) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement
or post-effective amendment to the Shelf Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Registrable Securities,
the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading; 

(xvii) provide a CUSIP number for all Securities not later than the effective date of the Registration Statement covering such
Securities and provide the Trustee under the Indenture with printed certificates for such Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action necessary to ensure that all such Securities
are eligible for deposit with the Depository Trust Company; 
 (xviii) use commercially reasonable efforts to cooperate and
assist in any filings required to be made with FINRA; 

  
 -12- 

 (xix) otherwise use its commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission, and make generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) for the twelve-month
period (A) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in a firm commitment or best efforts underwritten offering or (B) if not sold to underwriters in such an offering, beginning
with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement; and 

(xx) cause the applicable Indenture to be qualified under the Trust Indenture Act not later than the effective date of the
first Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders of Securities to effect such changes to the Indenture as may be required for such Indenture to be so qualified in
accordance with the terms of the Trust Indenture Act; and to execute and use its commercially reasonable efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to
be filed with the Commission to enable such Indenture to be so qualified in a timely manner. 
 Each Holder agrees by acquisition of a
Registrable Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to
the applicable Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof, or until it is advised in writing (the “Advice”) by the
Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will deliver to the Company (at
the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that was current at the time of receipt of such notice. In the event the Company
shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of
the giving of such notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by
Section 6(c)(xvi) hereof or shall have received the Advice; provided, however, that no such extension shall be taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such
Additional Interest, it being agreed that the Company’s option to suspend use of a Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 

  
 -13- 

 SECTION 7. Registration Expenses. 

(a) All expenses incident to the Company’s performance of or compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Dealer Manager or Holder with FINRA (and, if applicable, the reasonable and
documented fees and out-of-pocket expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of
FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and
printing of Prospectuses), messenger and delivery services; (iv) all reasonable and documented fees and out-of-pocket disbursements of counsel for the Company and,
subject to Section 7(b) hereof, the Holders of Registrable Securities; and (v) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required
by or incident to such performance). 
 The Company will, in any event, bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 

(b) In connection with any Shelf Registration Statement required by this Agreement, the Company will reimburse the Holders of Registrable
Securities registered pursuant to the Shelf Registration Statement for the reasonable and documented fees and out-of-pocket disbursements of not more than one counsel,
who shall be Simpson Thacher & Bartlett LLP or such other counsel as may be chosen by the Holders of a majority in principal amount of the Registrable Securities for whose benefit such Registration Statement is being prepared. 

(c) Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such
Holder’s Registrable Securities pursuant to a Registration Statement. 
 SECTION 8. Indemnification. 

(a) The Company agrees to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective
officers and directors, of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any
and all losses, claims, damages, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending
any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable and documented fees and
out-of-pocket expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based upon, arising out of or in connection
with any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities, judgments, actions or expenses are caused by an untrue statement or omission or alleged untrue statement or
omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any
liability which the Company may otherwise have. 

  
 -14- 

 In case any action or proceeding (including any governmental or regulatory investigation or
proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Company, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall
promptly notify the Company in writing; provided, however, that the failure to give such notice shall not relieve the Company of its obligations pursuant to this Agreement except to the extent that it has been prejudiced by such failure
(through the forfeiture of substantive rights and defenses) and shall not relieve the Company from any liability which it may have to any Indemnified Holder other than under this Agreement. The Company shall be entitled to participate therein and,
to the extent it shall elect, jointly with any other indemnifying party similarly notified, by written notice delivered to the Indemnified Holder promptly after receiving the aforesaid notice from such Indemnified Holder, to assume the defense
thereof, with counsel reasonably satisfactory to such Indemnified Holder. Any Indemnified Holder shall have the right to retain its own counsel if (i) the Company does not elect to so assume the defense thereof within a reasonable time after
notice of commencement of action, (ii) the named parties to any such action (including any impleaded parties) include both the Company and the Indemnified Holder and representation of both parties by the same counsel would be inappropriate due
to actual or potential differing interests between them, (iii) there are legal defenses available to the Indemnified Holder and/or other Indemnified Holders which are different from or additional to those available to the Company or
(iv) the Company and the Indemnified Holder shall have mutually agreed to the retention of such counsel, and the reasonable and documented fees and out-of-pocket
expenses of such counsel shall be paid, as incurred, by the Company (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to indemnification hereunder). The Company shall not, in connection with any one such
action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable and documented fees and out-of-pocket expenses of more than one separate firm of attorneys (in addition to any one local counsel in each jurisdiction) at any time for such Indemnified Holders, which
firm shall be designated by the Holders. The Company shall be liable for any settlement of any such action or proceeding effected with the Company’s prior written consent, which consent shall not be withheld unreasonably, and the Company agrees
to indemnify and hold harmless any Indemnified Holder from and against any loss, claim, damage, liability or expense by reason of any settlement of any action effected with the written consent of the Company. The Company shall not, without the prior
written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Holder from all liability arising out
of such action, claim, litigation or proceeding. 

  
 -15- 

 (b) Each Holder of Registrable Securities agrees, severally and not jointly, to indemnify
and hold harmless the Company and each of its directors, officers of the Company who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the
Company, and the respective officers and directors of each such Person, to the same extent as the foregoing indemnity from the Company to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to
such Holder furnished in writing by such Holder expressly for use in any Registration Statement. In case any action or proceeding shall be brought against the Company or its directors or officers or any such controlling person in respect of which
indemnity may be sought against a Holder of Registrable Securities, such Holder shall have the rights and duties given the Company, and the Company, its directors and officers and such controlling person shall have the rights and duties given to
each Holder by the preceding paragraph. 
 (c) If the indemnification provided for in this Section 8 is unavailable to an indemnified
party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or expenses referred to therein, then each applicable
indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative benefits received by the Company, on the one hand, and the Holders, on the other hand, from the exchange of Initial Securities (which in the case of the Company shall be deemed to be equal to the total principal amount of the
Initial Securities), the amount of Additional Interest which did not become payable as a result of the Consummation of the Exchange Offer resulting in such losses, claims, damages, liabilities, judgments actions or expenses, and the Registration
Statement, or if such allocation is not permitted by applicable law, the relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which resulted in such losses, claims,
damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of the Indemnified Holder on the other shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Indemnified Holders, on the other hand, and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other reasonable and documented fees or
out-of-pocket expenses reasonably incurred by such party in connection with investigating or defending any action or claim. 

The Company and each Holder of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this
Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the immediately 

  
 -16- 

 
preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other reasonable and documented fees or out-of-pocket expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, none of the
Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total discount received by such Holder with respect to the Initial Securities exceeds the amount of any
damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective
principal amount of Initial Securities held by each of the Holders hereunder and not joint. 
 SECTION 9. Rule 144A. The Company
hereby agrees with each Holder of a series of Registrable Securities, for so long as any Registrable Securities of such series remain outstanding (unless the Company is subject to and complies with Section 13 or 15(d) of the Exchange Act), to
make available to such Holder or beneficial owner of such Registrable Securities in connection with any sale thereof and any prospective purchaser of such Registrable Securities from such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Securities Act in order to permit resales of such Registrable Securities pursuant to Rule 144A under the Securities Act. 

SECTION 10. Miscellaneous. 

(a) Remedies. The Company hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate. 

(b) No Inconsistent Agreements. The Company will not on or after the date of this Agreement enter into any agreement with respect to
its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company’s securities under any agreement in effect on the date hereof. 
 (c) Adjustments
Affecting the Securities. The Company will not take any action, or permit any change to occur, with respect to the Securities that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer. 

(d) Amendments and Waivers. The provisions of this Agreement, with respect to any series of Registrable Securities, may not be amended,
modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof and this Section 10(d)(i), obtained the written consent of

  
 -17- 

 
Holders of all outstanding Registrable Securities of such series and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding
principal amount of Registrable Securities of such series (excluding any Registrable Securities held by the Company or its affiliates). Notwithstanding the foregoing, a waiver or consent to or departure from the provisions hereof that relates
exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange
Offer may be given by the Holders of a majority of the outstanding principal amount of applicable Registrable Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the
rights of any Dealer Manager hereunder, the Company shall obtain the written consent of each such Dealer Manager with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective.
