(d) The following defined terms used in this Article V shall, unless the context otherwise requires, have the meanings specified below.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer 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 applicable 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 Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the applicable Redemption Date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the applicable 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 applicable Remaining Life – and shall interpolate to the applicable 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 applicable Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the applicable 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 applicable Redemption Date.

7

If on the third Business Day preceding the applicable Redemption Date H.15 TCM is no longer published, the Issuer shall calculate the applicable Treasury Rate 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 applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer 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 applicable 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 Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(e) The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof. The Trustee shall have no responsibility for any calculation or determination in respect of the Redemption Price of any Notes, or any component thereof, and shall be entitled to receive, and fully-protected in relying upon, an Officer’s Certificate from the Issuer that states such Redemption Price.

Section 5.02 Par Call. Any time on or after the 2027 Par Call Date, with respect to the 2027 Notes, the 2035 Par Call Date, with respect to the 2035 Notes, and the 2055 Par Call Date, with respect to the 2055 Notes, the Issuer may redeem the applicable series of Notes, in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus in each case, accrued and unpaid interest on the Notes being redeemed to, but excluding, such Redemption Date.

Section 5.03 No Sinking Fund. None of the Notes are entitled to the benefit of any sinking fund.

The Trustee will then reasonably promptly, mail or electronically deliver (or otherwise transmit in accordance with DTC’s (or any successor depositary’s) procedures), such notice of Special Mandatory Redemption to each registered Holder of 2027 Notes.

BLACKROCK FUNDING, INC.

4.600% Note due 2027

This Security is one of a duly authorized issue of securities of the Issuer (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 14, 2024 (the “Base Indenture”), as amended and supplemented by a Second Supplemental Indenture, dated as of July 26, 2024 (the “Second Supplemental Indenture” and the Base Indenture, as amended and supplemented by the Second Supplemental Indenture, the “Indenture”), among the Issuer, BlackRock, Inc., a corporation duly organized and existing under the laws of Delaware (herein called the “Guarantor,” which term includes any successor Person under the Indenture hereinafter referred to), and The Bank of New York Mellon, 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 Issuer, the Guarantor the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $800,000,000 (EIGHT HUNDRED MILLION DOLLARS). The Issuer may, from time to time, without the consent of the holders of the Securities of this series, issue additional Securities under the Indenture having the same ranking and the same interest rate, maturity and other terms as this series of Securities. Any additional Securities having such similar terms, together with any outstanding Securities of this series, will constitute a single series of Securities under the Indenture; provided that if the additional Securities are not fungible with the Securities of such series for U.S. federal income tax purposes, such additional Securities will be issued with a separate CUSIP number.

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, prior to June 26, 2027 (one month prior to the Stated Maturity of the Securities of this series) (the “Par Call Date”) at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest on the Securities being redeemed to, but excluding, the Redemption Date.

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, on or after the Par Call Date at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

A-4

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer 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 Issuer 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 Issuer shall calculate the Treasury Rate 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 Issuer 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 Issuer 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.

A-5

The Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof and the Trustee shall have no duty to determine, or verify the calculation of, the Redemption Price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Securities of this series to be redeemed.

In the case of a partial redemption, selection of definitive Securities for redemption will be by lot. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security in the definitive form is to be redeemed in part only, the notice of redemption that relates to such Security will state the portion of the principal amount of the Security to be redeemed. A new definitive Security in a principal amount equal to the unredeemed portion of such Security will be issued in the name of the holder of such Security upon surrender for cancellation of the original definitive Security. For so long as the Securities are held by DTC (or another depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the depositary, which may be made on a pro rata pass-through distribution of principal basis.

Any redemption notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Issuer’s discretion, the Redemption Date may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions shall be satisfied or waived, 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 Issuer in its sole discretion) by the Redemption Date, or by the Redemption Date as so delayed.

Unless the Issuer 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.

The Securities of this series are subject to a Special Mandatory Redemption as provided in Article VI of the Second Supplemental Indenture.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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.

This Security is entitled to the benefits of a full and unconditional guarantee by the Guarantor for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantor, the Trustee and the Holders. The guarantee of the Guarantor may be released in the circumstances as set forth in Section 1605 of the Indenture, including in certain circumstances without the consent of Holders.

A-6

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantor and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer, the Guarantor and the Trustee with the consent of the Holders of at least a majority in aggregate 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 Issuer 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.

As provided in and subject to the provisions of the Indenture, the Holder of this Security 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 such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 33% in principal amount of the Securities of this series 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 satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Security 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.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples 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 this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

A-7

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

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer 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 Issuer, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

This Security is one of a duly authorized issue of securities of the Issuer (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 14, 2024 (the “Base Indenture”), as amended and supplemented by a Second Supplemental Indenture, dated as of July 26, 2024 (the “Second Supplemental Indenture” and the Base Indenture, as amended and supplemented by the Second Supplemental Indenture, the “Indenture”), among the Issuer, BlackRock, Inc., a corporation duly organized and existing under the laws of Delaware (herein called the “Guarantor,” which term includes any successor Person under the Indenture hereinafter referred to), and The Bank of New York Mellon, 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 Issuer, the Guarantor the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $500,000,000 (FIVE HUNDRED MILLION DOLLARS). The Issuer may, from time to time, without the consent of the holders of the Securities of this series, issue additional Securities under the Indenture having the same ranking and the same interest rate, maturity and other terms as this series of Securities. Any additional Securities having such similar terms, together with any outstanding Securities of this series, will constitute a single series of Securities under the Indenture; provided that if the additional Securities are not fungible with the Securities of such series for U.S. federal income tax purposes, such additional Securities will be issued with a separate CUSIP number.

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, prior to October 8, 2034 (three months prior to the Stated Maturity of the Securities of this series) (the “Par Call Date”) at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest on the Securities being redeemed to, but excluding, the Redemption Date.

B-4

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, on or after the Par Call Date at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer 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 Issuer 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 Issuer shall calculate the Treasury Rate 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 Issuer 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 Issuer 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.

B-5

The Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof and the Trustee shall have no duty to determine, or verify the calculation of, the Redemption Price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Securities of this series to be redeemed.

In the case of a partial redemption, selection of definitive Securities for redemption will be by lot. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security in the definitive form is to be redeemed in part only, the notice of redemption that relates to such Security will state the portion of the principal amount of the Security to be redeemed. A new definitive Security in a principal amount equal to the unredeemed portion of such Security will be issued in the name of the holder of such Security upon surrender for cancellation of the original definitive Security. For so long as the Securities are held by DTC (or another depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the depositary, which may be made on a pro rata pass-through distribution of principal basis.

Any redemption notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Issuer’s discretion, the Redemption Date may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions shall be satisfied or waived, 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 Issuer in its sole discretion) by the Redemption Date, or by the Redemption Date as so delayed.

Unless the Issuer 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.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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.

This Security is entitled to the benefits of a full and unconditional guarantee by the Guarantor for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantor, the Trustee and the Holders.

BLACKROCK FUNDING, INC.

5.350% Note due 2055

This Security is one of a duly authorized issue of securities of the Issuer (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 14, 2024 (the “Base Indenture”), as amended and supplemented by a Second Supplemental Indenture, dated as of July 26, 2024 (the “Second Supplemental Indenture” and the Base Indenture, as amended and supplemented by the Second Supplemental Indenture, the “Indenture”), among the Issuer, BlackRock, Inc., a corporation duly organized and existing under the laws of Delaware (herein called the “Guarantor,” which term includes any successor Person under the Indenture hereinafter referred to), and The Bank of New York Mellon, 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 Issuer, the Guarantor the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $1,200,000,000 (ONE BILLION, TWO HUNDRED MILLION DOLLARS). The Issuer may, from time to time, without the consent of the holders of the Securities of this series, issue additional Securities under the Indenture having the same ranking and the same interest rate, maturity and other terms as this series of Securities. Any additional Securities having such similar terms, together with any outstanding Securities of this series, will constitute a single series of Securities under the Indenture; provided that if the additional Securities are not fungible with the Securities of such series for U.S. federal income tax purposes, such additional Securities will be issued with a separate CUSIP number.

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, prior to July 8, 2054 (six months prior to the Stated Maturity of the Securities of this series) (the “Par Call Date”) at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest on the Securities being redeemed to, but excluding, the Redemption Date.

C-4

The Securities of this series will be redeemable in whole or in part, at the Issuer’s option at any time and from time to time, on or after the Par Call Date at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer 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 Issuer 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 Issuer shall calculate the Treasury Rate 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 Issuer 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 Issuer 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.

C-5

The Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Issuer will notify the Trustee of the Redemption Price promptly after the calculation thereof and the Trustee shall have no duty to determine, or verify the calculation of, the Redemption Price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each holder of Securities of this series to be redeemed.

In the case of a partial redemption, selection of definitive Securities for redemption will be by lot. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security in the definitive form is to be redeemed in part only, the notice of redemption that relates to such Security will state the portion of the principal amount of the Security to be redeemed. A new definitive Security in a principal amount equal to the unredeemed portion of such Security will be issued in the name of the holder of such Security upon surrender for cancellation of the original definitive Security. For so long as the Securities are held by DTC (or another depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the depositary, which may be made on a pro rata pass-through distribution of principal basis.

Any redemption notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Issuer’s discretion, the Redemption Date may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions shall be satisfied or waived, 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 Issuer in its sole discretion) by the Redemption Date, or by the Redemption Date as so delayed.

Unless the Issuer 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.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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.

This Security is entitled to the benefits of a full and unconditional guarantee by the Guarantor for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantor, the Trustee and the Holders. The guarantee of the Guarantor may be released in the circumstances as set forth in Section 1605 of the Indenture, including in certain circumstances without the consent of Holders.

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 Issuer 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.

As provided in and subject to the provisions of the Indenture, the Holder of this Security 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 such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 33% in principal amount of the Securities of this series 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 satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Security 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.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples 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 this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
