(2) Each Global Note will be delivered to the Trustee as custodian for the Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (x) as set forth in Section 2.3(b)(4) and (y) transfers of portions thereof in the form of Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Company or the Trustee, on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section and Section 2.2.

(3) Agent Members will have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary shall be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under the Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(4) If (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing, any owner of a beneficial interest in such Global Note will be entitled to receive a Certificated Note in exchange for such interest, whether or not the Trustee has received a request from the Depositary, and the Company will promptly execute one or more Certificated Notes in authorized denominations having an equal aggregate principal amount of such Global Note, registered in the name of the owner of the beneficial interest of each such Global Note, as identified to the Trustee by the Depositary. The Trustee will authenticate and deliver such Certificated Notes in exchange for such Global Note and thereupon the Global Note will be deemed canceled upon issuance of such Certificated Notes. If such Note was an Offshore Global Note, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend.

(c) Certificated Notes. Each Certificated Note will be registered in the name of the Holder thereof or its nominee.

(d) Transfers and Exchanges Generally.

(1) Global Notes. Transfers of beneficial interests in any Global Notes shall be transferred pursuant to the policies and procedures of the Depositary.

(2) Certificated Notes. A Holder may transfer a Certificated Note (or a beneficial interest therein) to another Person or exchange a Certificated Note (or a beneficial interest therein) for another Certificated Note or Certificated Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.2. The Trustee will promptly register any such transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that (x) no transfer or exchange will be effective until the transfer or exchange is registered in such register and (y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Certificated Note for a period of 15 days before a selection of Certificated Notes to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any Certificated Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption (or purchase), that portion of any Certificated Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Certificated Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the person in whose name the Certificated Note is registered as the owner and Holder thereof for all purposes (whether or not the Certificated Note is overdue), and will not be affected by notice to the contrary.

From time to time the Company will execute and the Trustee will authenticate additional Certificated Notes as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

No service charge will be imposed in connection with any transfer or exchange of any Certificated Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to paragraph (b)(4)).

(e) Procedures to Be Followed. (1) Global Note to Global Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, such transfer or exchange shall be made pursuant to the policies and procedures of the Depositary. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(2) Global Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated Notes in authorized denominations having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable.

(3) Certificated Note to Global Note. If a Certificated Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

(4) Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

[FORM OF REVERSE OF SECURITY]

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

Indenture. This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under the Indenture, dated as of August 31, 2026 (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of August 31, 2026 (herein called the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as Trustee (herein called 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 of the Securities and of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, issued initially in aggregate principal amount to $________.

Optional Redemption. Prior to July 15, 2031 (the “Par Call Date”), the Company may redeem the Securities of this series at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities of this series matured on the Par Call Date), on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date; and

(2) 100% of the principal amount of the Securities to be redeemed;

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities of this series, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

This Security is also subject to a Special Mandatory Redemption as provided in Article IV of the First Supplemental Indenture.
 

“Treasury Rate” means, with respect to any Redemption Date for the Securities of this series, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate applicable to redemption of the Securities of this series shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent

statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate applicable to such redemption based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Company will notify the Trustee of the redemption price promptly after the calculation thereof and the Trustee shall not be responsible or liable for any calculation of the redemption price or of any component thereof, or for determining whether manifest error has occurred.

Any redemption and notice of such redemption may, at the Company’s option, be subject to the satisfaction of one or more conditions precedent. If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Company) by the Redemption Date, or by the Redemption Date as so delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

Unless the Company defaults in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Except as set forth herein, the Securities of this series will not be redeemable by the Company prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund.

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Change of Control. If a Change of Control Triggering Event occurs with respect to the Securities of this series, unless the Company has exercised its option to redeem the Securities of this series in accordance with the provisions set forth in this Security under the heading “Optional Redemption”, Holders of the Securities will have the right to require the Company to repurchase all or any part (equal to $2,000 and any integral multiple of $1,000 in excess thereof) of their Securities as described in Article IV of the Supplemental Indenture.

Amendment, Modification and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment and 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 aggregate principal amount of the Outstanding Securities (as defined in the Base Indenture) affected by such amendment, supplement or modification voting as a single class. The Indenture also contains provisions permitting the Holders of a majority in aggregate 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

Restrictive Covenants. The restrictive covenants for this Security are as specified in the Indenture. The Indenture does not limit unsecured debt of the Company or any of its Subsidiaries.

Denominations, Transfer and Exchange. The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 or any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Persons Deemed Owners. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Miscellaneous. The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law rules of said State.

Date of authentication:

[FORM OF REVERSE OF SECURITY]

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

Indenture. This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under the Indenture, dated as of August 31, 2026 (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of August 31, 2026 (herein called the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as Trustee (herein called 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 of the Securities and of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, issued initially in aggregate principal amount to $________.

Optional Redemption. Prior to May 15, 2036 (the “Par Call Date”), the Company may redeem the Securities of this series at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

(1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities of this series matured on the Par Call Date), on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date; and

(2) 100% of the principal amount of the Securities to be redeemed;

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities of this series, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

This Security is also subject to a Special Mandatory Redemption as provided in Article IV of the First Supplemental Indenture.

“Treasury Rate” means, with respect to any Redemption Date for the Securities of this series, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate applicable to redemption of the Securities of this series shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent

statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate applicable to such redemption based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Company will notify the Trustee of the redemption price promptly after the calculation thereof and the Trustee shall not be responsible or liable for any calculation of the redemption price or of any component thereof, or for determining whether manifest error has occurred.

Any redemption and notice of such redemption may, at the Company’s option, be subject to the satisfaction of one or more conditions precedent. If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Company) by the Redemption Date, or by the Redemption Date as so delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

Unless the Company defaults in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Except as set forth herein, the Securities of this series will not be redeemable by the Company prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund.

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Change of Control. If a Change of Control Triggering Event occurs with respect to the Securities of this series, unless the Company has exercised its option to redeem the Securities of this series in accordance with the provisions set forth in this Security under the heading “Optional Redemption”, Holders of the Securities will have the right to require the Company to repurchase all or any part (equal to $2,000 and any integral multiple of $1,000 in excess thereof) of their Securities as described in Article IV of the Supplemental Indenture.

Amendment, Modification and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment and 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 aggregate principal amount of the Outstanding Securities (as defined in the Base Indenture) affected by such amendment, supplement or modification voting as a single class. The Indenture also contains provisions permitting the Holders of a majority in aggregate 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

Restrictive Covenants. The restrictive covenants for this Security are as specified in the Indenture. The Indenture does not limit unsecured debt of the Company or any of its Subsidiaries.

Denominations, Transfer and Exchange. The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 or any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Persons Deemed Owners. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Miscellaneous. The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law rules of said State.
