TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This Note is one or all of the Securities of the series of 2031 Notes designated, described or provided for in the within-mentioned Indenture.

Dated: June 24, 2025

U.S. BANK TRUST COMPANY, NATIONAL ASSOCIATION, as Trustee

[REVERSE SIDE OF NOTE]

6.150% Green Senior Unsecured Note due 2031

1. Indenture. This Note is one or all of a duly authorized issue of securities of the Company issued and to be issued in one or more series under the Indenture, dated as of June 24, 2025 (the “Base Indenture”), by and among the Company, the Guarantors and U.S. Bank Trust Company, National Association, as trustee (the “Base Trustee”), as amended and supplemented from time to time, including without limitation, pursuant to the Officer’s Certificate, dated June 24, 2025 (the “Officer’s Certificate” and, together with the Base Indenture, the “Indenture”), establishing the specific terms and form of this Note and appointing U.S. Bank Trust Company, National Association to serve as trustee with respect to the Notes (the “Trustee”, which term includes any successor trustee thereunder), which Indenture reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one or all of the securities of the Series issued hereby and designated as the “6.150% Green Senior Unsecured Notes due 2031” (the “Notes”).

The Company appointed U.S. Bank Trust Company, National Association as Trustee, Paying Agent, and Security Registrar with respect to the Notes, with all of the rights, powers, and duties under the Indenture with respect to the Notes, and U.S. Bank Trust Company, National Association, by execution of an Acknowledgement to the Officer’s Certificate, accepted such appointment. The Base Trustee will continue to serve as the trustee under the Base Indenture with respect to the existing Series of securities outstanding as to which it has served and continues to serve as trustee under the Base Indenture, and for all other purposes under the Base Indenture (other than with respect to the Notes and the Company’s 6.750% Green Senior Unsecured Notes due 2035 issued simultaneously herewith).

2. Optional Redemption. Prior to December 15, 2030 (one month prior to the maturity date of the Notes) (the “Par Call Date”), the Company may redeem the Notes 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 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 Notes 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 (as defined below) plus 35 basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the Notes 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 Notes at its option, 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 Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on an Interest Payment Date falling on or prior to a Redemption Date will be payable on that Interest Payment Date to the Holders as of the close of business on the relevant record date according to the Notes and the Indenture.

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

The Treasury Rate 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 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 Trustee shall have no duty or responsibility 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 the Notes to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on any Notes or portions thereof called for redemption. If less than all the Notes are to be redeemed, the Trustee will select the Notes to be redeemed pro rata, by lot, or by another method compliant with applicable legal and securities exchange requirements, if any, and that the Trustee deems to be fair and appropriate in accordance with DTC’s procedures.

3. Offer to Repurchase Upon a Change of Control Repurchase Event. If a Change of Control Repurchase Event (as defined below) occurs, unless the Company has exercised its option to redeem the Notes as provided under the heading “Optional Redemption,” the Company shall make an offer to each Holder of Notes to repurchase all or any part of that Holder’s Notes (the “Change of Control Offer”) at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but excluding, the date of repurchase (the “Repurchase Price”).

In connection with any Change of Control related to a Change of Control Repurchase Event and any particular reduction in the rating on the Notes, the Company shall request from the Rating Agencies (as defined below) each such Rating Agency’s written confirmation that such reduction in the rating on the Notes was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of any Below Investment Grade Rating Event). The Company shall promptly deliver an Officers’ Certificate to the Trustee certifying as to whether or not such confirmation has been received or denied.

Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall give notice to each Holder of Notes, with a written copy to the Trustee. Such notice shall state:

(A) a description of the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event;

(B) that a Change of Control Offer is being made pursuant to this Section 3;

(C) the Repurchase Price and the date on which the Repurchase Price will be paid, which date shall be a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed, other than as may be required by law (the “Repurchase Price Payment Date”); and

(D) if the notice is given prior to the date of consummation of the Change of Control, a statement that the Change of Control Offer is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

The Company shall comply with the applicable requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Repurchase Price Payment Date, the Company shall, to the extent lawful:

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

(F) deposit with the Paying Agent an amount equal to the aggregate Repurchase Price in respect of all Notes or portions of Notes properly tendered; and

(G) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Paying Agent shall promptly deliver to each Holder of Notes properly tendered the Repurchase Price for such Notes, and, upon receipt of a written direction from the Company, the Trustee shall promptly authenticate (if applicable) and deliver (or cause to be transferred by book-entry) to each Holder of Notes properly tendered a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note representing any unpurchased portion of any Notes surrendered will be in a minimum principal amount of $2,000 or any integral multiple of $1,000 in excess thereof.

Notwithstanding the foregoing, the Company shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if (i) a third party makes such an offer in respect of the Notes in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all the Notes properly tendered and not withdrawn in respect of its offer or (ii) the Company has given written notice of a redemption as provided under the heading “Optional Redemption”; provided that the Company has not failed to pay the redemption price on the redemption date.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the rating on the Notes is (A) lowered by two or more Rating Agencies in respect of a Change of Control and (B) the Notes are rated below Investment Grade (as defined below) by (i) both Rating Agencies if the Notes are rated by two Rating Agencies or (ii) two of such Rating Agencies if the Notes are rated by three Rating Agencies on any date from the date of the public notice of a transaction or transactions that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended until the ratings are announced if during such 60-day period the rating of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if each Rating Agency making the reduction

in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Company in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event). The Company will request the Rating Agencies to make such confirmation in connection with any Change of Control and shall promptly deliver an officer’s certificate to the Trustee certifying as to whether or not such confirmation has been received or denied.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This Note is one or all of the Securities of the series of 2035 Notes designated, described or provided for in the within-mentioned Indenture.

Dated: June 24, 2025

U.S. BANK TRUST COMPANY, NATIONAL ASSOCIATION, as Trustee

[REVERSE SIDE OF NOTE]

6.750% Green Senior Unsecured Note due 2035

1. Indenture. This Note is one or all of a duly authorized issue of securities of the Company issued and to be issued in one or more series under the Indenture, dated as of June 24, 2025 (the “Base Indenture”), by and among the Company, the Guarantors and U.S. Bank Trust Company, National Association, as trustee (the “Base Trustee”), as amended and supplemented from time to time, including without limitation, pursuant to the Officer’s Certificate, dated June 24, 2025 (the “Officer’s Certificate” and, together with the Base Indenture, the “Indenture”), establishing the specific terms and form of this Note and appointing U.S. Bank Trust Company, National Association to serve as trustee with respect to the Notes (the “Trustee”, which term includes any successor trustee thereunder), which Indenture reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one or all of the securities of the Series issued hereby and designated as the “6.750% Green Senior Unsecured Notes due 2035” (the “Notes”).

The Company appointed U.S. Bank Trust Company, National Association as Trustee, Paying Agent, and Security Registrar with respect to the Notes, with all of the rights, powers, and duties under the Indenture with respect to the Notes, and U.S. Bank Trust Company, National Association, by execution of an Acknowledgement to the Officer’s Certificate, accepted such appointment. The Base Trustee will continue to serve as the trustee under the Base Indenture with respect to the existing Series of securities outstanding as to which it has served and continues to serve as trustee under the Base Indenture, and for all other purposes under the Base Indenture (other than with respect to the Notes and the Company’s 6.150% Green Senior Unsecured Notes due 2031 issued simultaneously herewith).

2. Optional Redemption. Prior to April 15, 2035 (three months prior to the maturity date of the Notes) (the “Par Call Date”), the Company may redeem the Notes 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 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 Notes 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 (as defined below) plus 40 basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the Notes 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 Notes at its option, 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 Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on an Interest Payment Date falling on or prior to a Redemption Date will be payable on that Interest Payment Date to the Holders as of the close of business on the relevant record date according to the Notes and the Indenture.

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

The Treasury Rate 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 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 Trustee shall have no duty or responsibility 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 the Notes to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on any Notes or portions thereof called for redemption. If less than all the Notes are to be redeemed, the Trustee will select the Notes to be redeemed pro rata, by lot, or by another method compliant with applicable legal and securities exchange requirements, if any, and that the Trustee deems to be fair and appropriate in accordance with DTC’s procedures.

3. Offer to Repurchase Upon a Change of Control Repurchase Event. If a Change of Control Repurchase Event (as defined below) occurs, unless the Company has exercised its option to redeem the Notes as provided under the heading “Optional Redemption,” the Company shall make an offer to each Holder of Notes to repurchase all or any part of that Holder’s Notes (the “Change of Control Offer”) at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but excluding, the date of repurchase (the “Repurchase Price”).

In connection with any Change of Control related to a Change of Control Repurchase Event and any particular reduction in the rating on the Notes, the Company shall request from the Rating Agencies (as defined below) each such Rating Agency’s written confirmation that such reduction in the rating on the Notes was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of any Below Investment Grade Rating Event). The Company shall promptly deliver an Officers’ Certificate to the Trustee certifying as to whether or not such confirmation has been received or denied.

Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall give notice to each Holder of Notes, with a written copy to the Trustee. Such notice shall state:

(A) a description of the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event;

(B) that a Change of Control Offer is being made pursuant to this Section 3;

(C) the Repurchase Price and the date on which the Repurchase Price will be paid, which date shall be a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed, other than as may be required by law (the “Repurchase Price Payment Date”); and

(D) if the notice is given prior to the date of consummation of the Change of Control, a statement that the Change of Control Offer is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

The Company shall comply with the applicable requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Repurchase Price Payment Date, the Company shall, to the extent lawful:

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

(F) deposit with the Paying Agent an amount equal to the aggregate Repurchase Price in respect of all Notes or portions of Notes properly tendered; and

(G) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Paying Agent shall promptly deliver to each Holder of Notes properly tendered the Repurchase Price for such Notes, and, upon receipt of a written direction from the Company, the Trustee shall promptly authenticate (if applicable) and deliver (or cause to be transferred by book-entry) to each Holder of Notes properly tendered a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note representing any unpurchased portion of any Notes surrendered will be in a minimum principal amount of $2,000 or any integral multiple of $1,000 in excess thereof.

Notwithstanding the foregoing, the Company shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if (i) a third party makes such an offer in respect of the Notes in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all the Notes properly tendered and not withdrawn in respect of its offer or (ii) the Company has given written notice of a redemption as provided under the heading “Optional Redemption”; provided that the Company has not failed to pay the redemption price on the redemption date.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the rating on the Notes is (A) lowered by two or more Rating Agencies in respect of a Change of Control and (B) the Notes are rated below Investment Grade (as defined below) by (i) both Rating Agencies if the Notes are rated by two Rating Agencies or (ii) two of such Rating Agencies if the Notes are rated by three Rating Agencies on any date from the date of the public notice of a transaction or transactions that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended until the ratings are announced if during such 60-day period the rating of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if each Rating Agency making the reduction

in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Company in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event). The Company will request the Rating Agencies to make such confirmation in connection with any Change of Control and shall promptly deliver an officer’s certificate to the Trustee certifying as to whether or not such confirmation has been received or denied.
