Cautionary Statement Concerning Forward-Looking Statements
This current report on Form 8-K contains forward-looking statements that are not historical facts, including statements about the anticipated use of proceeds from the sale of the Notes. These statements are based on current expectations and assumptions, which management believes are reasonable, and on information currently available to management, but are necessarily subject to various risks and uncertainties. In addition to the risk that these assumptions prove to be inaccurate, factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include factors disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, and its subsequent filings with the SEC, which are available on the Company’s website at www.nisource.com and on the SEC’s website at www.sec.gov. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether due to new information, future events or otherwise, except to the extent required by law.

1.
Interest
NiSource Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being
herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will pay interest semiannually on May 18 and November 18 of each year, beginning
November 18, 2026. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from May 18, 2026. Interest will be computed on the basis of a
360-day year of twelve 30-day months. The Company will pay interest on overdue principal and premium at the above rate and will pay interest on overdue installments of
interest at such rate to the extent lawful.
2.
Method of Payment
The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of
business on the Regular Record Date next preceding each Interest Payment Date even if Notes are canceled after the Regular Record Date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including
principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC, as Depositary.
3.
Paying Agent and Security Registrar
Initially, the Trustee will act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent or Security
Registrar without notice to the Holders. The Company may act as Paying Agent or Security Registrar.
4.
Indenture
The Company issued the Notes under an Indenture dated as of November 14, 2000, by and between the Company, in its own capacity and as
successor to NiSource Finance Corp., and the Trustee (as successor trustee) (as amended and supplemented, the “Indenture”) and pursuant to an Officers’ Certificate of the Company dated May 18, 2026 (the
“Officers’ Certificate”). The terms of the Notes include those stated in the Indenture and the Officers’ Certificate and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
sections 77aaa-77bbbb) as in effect on the date of the Officers’ Certificate (the “Act”). Capitalized terms used herein and defined in the Indenture but not defined herein have the respective meanings ascribed thereto in the
Indenture. The Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the Act for a statement of those terms.
The Notes are senior unsecured obligations of the Company. The Notes issued on the original issue date will be treated as a single class for
all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Subsidiaries (other than Utilities) to incur additional indebtedness and create liens on assets unless the total amount of all the
secured debt would not exceed 10% of Consolidated Net Tangible Assets (excluding the Utilities). These covenants are subject to important exceptions and qualifications.
5.
Optional Redemption
Prior to April 18, 2031 (one month prior to the maturity date of the Notes) (the “Par Call Date”), the Company will
have the right to 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 plus 12.5 basis points less (b) interest accrued to the Redemption Date, 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 will have the right to 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.
“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 Trustee
shall have no duty to calculate the Redemption Price.
6.
Tax Credit Event Redemption
If a Tax Credit Event occurs, the Company will have the right to redeem the Notes, at its option, in whole but not in part, at a Redemption
Price equal to 101% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.
Notice of any redemption of the Notes upon the occurrence of a Tax Credit Event (i) may only be sent by the later of (a) the end of
the calendar year in which the Notes were issued and (b) six months after the date of issuance of the Notes and (ii) shall be accompanied by a certificate from an officer of the Company stating that a Tax Credit Event has occurred.
The consummation of a redemption of the Notes upon a Tax Credit Event may be subject to the Paying Agent’s receipt of the required
redemption moneys on or before the Redemption Date (and in such case no redemption shall occur unless such moneys have been received by the Paying Agent on or before such date).
A “Tax Credit Event” has occurred if, in the Company’s reasonable determination, there exists a material risk, due to the
Notes (considered together with other debt) having been issued, as part of an original issuance, to one or more “specified foreign entities,” as defined in Section 7701(a)(51)(B) of the Internal Revenue Code of 1986, as amended (the
“Code”), that the Company or any of its affiliates would be unable to utilize or otherwise ineligible to claim any tax credits otherwise allowed under Section 38 of the Code.
7.
Notice of Redemption
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 Notes to be redeemed in accordance with Section 106 of the Indenture. In the case of a partial redemption, if the Notes to be redeemed are held
in certificated form, selection of the Notes for redemption will be made by the Trustee, by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that
relates to such Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of the original Note upon
surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes, including selection of the Notes for redemption, shall be done in accordance with the policies and
procedures of the depositary and may be made on a pro rata pass-through distribution of principal basis. The Company will not know the exact Redemption Price until approximately two (2) to three (3) Business Days before the Redemption
Date. Therefore, the notice of redemption will only describe how the Redemption Price will be calculated. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or
portions thereof called for redemption.
8.
Additional Notes
The Company may, without the consent of the Holders of the Notes, create and issue additional Notes ranking equally with the Notes in all
respects, including having the same terms (except for the price to public, the issue date and the initial interest accrual date and the first Interest Payment Date, as applicable), so that such additional Notes shall be consolidated and form a
single series with the Notes and shall have the same terms as to status, redemption or otherwise as the Notes. Such additional Notes will have the same CUSIP number as the Notes being authenticated on the date hereof, provided that such additional
Notes are part of the same issue as the Notes being authenticated on the date hereof for U.S. federal income tax purposes. If such additional Notes are not part of the same issue for U.S. federal income tax purposes, such additional Notes must be
issued with a separate CUSIP number. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.
9.
Denominations; Transfer; Exchange
The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000. A Holder may
transfer or exchange Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Security Registrar need not register the transfer or exchange of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) for a period of fifteen
(15) Business Days before a selection of Notes to be redeemed.
10.
Persons Deemed Owners
The registered Holder of this Note may be treated as the owner of it for all purposes.
11.
Unclaimed Money
If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or the Paying Agent for payment.
12.
Satisfaction and Discharge
Under the Indenture, the Company can terminate its obligations with respect to the Notes not previously delivered to the Trustee for
cancellation when those Notes have become due and payable or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving notice of
redemption. The Company may terminate its obligations with respect to the Notes by depositing with the Trustee, as funds in trust dedicated solely for that purpose, an amount sufficient to pay and discharge the entire indebtedness on the Notes. In
that case, the Indenture will cease to be of further effect and the Company’s obligations will be satisfied and discharged with respect to the Notes (except as to the Company’s obligations to pay all other amounts due under the Indenture
and to provide certain Officers’ Certificates and Opinions of Counsel to the Trustee). At the expense of the Company, the Trustee will execute proper instruments acknowledging the satisfaction and discharge.
13.
Amendment, Waiver
Subject to certain exceptions set forth in the Indenture, (i) the Indenture may be amended with the written consent of the Holders of a
majority in principal amount of the then Outstanding Securities of each series affected by such amendment, (ii) the Notes may be amended with the written consent of the Holders of at least a majority in principal amount of the Outstanding Notes
and (iii) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount of the Outstanding Notes. Subject to certain exceptions set forth in the Indenture, without the
consent of any Holder, the Company and the Trustee shall be entitled to amend the Indenture to, among other things, cure any ambiguity, defect or inconsistency, or to evidence the succession of another Person as obligor under the Indenture, or to
add to the Company’s covenants or to surrender any right or power conferred on the Company under the Indenture, or to add events of default, or to secure the Notes, or to evidence or provide for the acceptance or appointment by a successor
Trustee or facilitate the administration of the trusts under the Indenture by more than one trustee, or to conform the Indenture to any amendment of the Act.
14.
Defaults and Remedies
Under the Indenture, Events of Default include: (i) a default by the Company in the payment of any interest upon any Note and the
continuance of such default for 60 days; (ii) a default by the Company in the payment of principal of or any premium on any Note when due at Maturity, on redemption, by declaration or otherwise, and the continuance of such default for three
(3) Business Days; (iii) a default by the Company in the performance of or breach of any covenant or warranty in the Indenture and continuance of such default for 90 days after written notice has been given to the Company by the Trustee or
to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Notes; (iv) a default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company, or
the Company defaults under any mortgage, indenture or instrument under which there may be issued, secured or evidenced indebtedness constituting a failure to pay in excess of $50,000,000 of the principal or interest when due and payable, subject to
certain cure rights; or (v) certain events of bankruptcy, insolvency or reorganization involving the Company. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 33% in principal amount of the Outstanding
Notes may declare all the Notes to be due and payable immediately.
Holders may not enforce the Indenture or the Notes except as provided
in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee
in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.
15.
Trustee Dealings with the Company
Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.
16.
No Recourse Against Others
A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Notes.
17.
Authentication
This Note shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) signs the certificate of authentication
on the other side of this Note in accordance with requirements set forth in the Indenture and the Officers’ Certificate.
18.
Abbreviations
Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).
19.
CUSIP and ISIN Numbers
Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused the applicable
CUSIP number to be printed on the Notes and has directed the Trustee to use such CUSIP number in any notice of redemption as a convenience to the Holders. To the extent such number has been issued, the Company has caused the applicable ISIN number
to be similarly printed on the Notes and has similarly instructed the Trustee. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

[SIGNATURE PAGE TO GLOBAL NOTE NO. 1]
5.300% Notes due 2036
1.
Interest
NiSource Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being
herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will pay interest semiannually on May 18 and November 18 of each year, beginning
November 18, 2026. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from May 18, 2026. Interest will be computed on the basis of a
360-day year of twelve 30-day months. The Company will pay interest on overdue principal and premium at the above rate and will pay interest on overdue installments of
interest at such rate to the extent lawful.
2.
Method of Payment
The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of
business on the Regular Record Date next preceding each Interest Payment Date even if Notes are canceled after the Regular Record Date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including
principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC, as Depositary.
3.
Paying Agent and Security Registrar
Initially, the Trustee will act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent or Security
Registrar without notice to the Holders. The Company may act as Paying Agent or Security Registrar.
4.
Indenture
The Company issued the Notes under an Indenture dated as of November 14, 2000, by and between the Company, in its own capacity and as
successor to NiSource Finance Corp., and the Trustee (as successor trustee) (as amended and supplemented, the “Indenture”) and pursuant to an Officers’ Certificate of the Company dated May 18, 2026 (the
“Officers’ Certificate”). The terms of the Notes include those stated in the Indenture and the Officers’ Certificate and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
sections 77aaa-77bbbb) as in effect on the date of the Officers’ Certificate (the “Act”). Capitalized terms used herein and defined in the Indenture but not defined herein have the respective meanings ascribed thereto in the
Indenture. The Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the Act for a statement of those terms.
The Notes are senior unsecured obligations of the Company. The Notes issued on the original issue date will be treated as a single class for
all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Subsidiaries (other than Utilities) to incur additional indebtedness and create liens on assets unless the total amount of all the
secured debt would not exceed 10% of Consolidated Net Tangible Assets (excluding the Utilities). These covenants are subject to important exceptions and qualifications.
5.
Optional Redemption
Prior to February 18, 2036 (three months prior to the maturity date of the Notes) (the “Par Call Date”), the Company
will have the right to 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 plus 15.0 basis points less (b) interest accrued to the Redemption Date, 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 will have the right to 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.
“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 Trustee
shall have no duty to calculate the Redemption Price.
6.
Tax Credit Event Redemption
If a Tax Credit Event occurs, the Company will have the right to redeem the Notes, at its option, in whole but not in part, at a Redemption
Price equal to 101% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.
Notice of any redemption of the Notes upon the occurrence of a Tax Credit Event (i) may only be sent by the later of (a) the end of
the calendar year in which the Notes were issued and (b) six months after the date of issuance of the Notes and (ii) shall be accompanied by a certificate from an officer of the Company stating that a Tax Credit Event has occurred.
The consummation of a redemption of the Notes upon a Tax Credit Event may be subject to the Paying Agent’s receipt of the required
redemption moneys on or before the Redemption Date (and in such case no redemption shall occur unless such moneys have been received by the Paying Agent on or before such date).
A “Tax Credit Event” has occurred if, in the Company’s reasonable determination, there exists a material risk, due to the
Notes (considered together with other debt) having been issued, as part of an original issuance, to one or more “specified foreign entities,” as defined in Section 7701(a)(51)(B) of the Internal Revenue Code of 1986, as amended (the
“Code”), that the Company or any of its affiliates would be unable to utilize or otherwise ineligible to claim any tax credits otherwise allowed under Section 38 of the Code.
7.
Notice of Redemption
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 Notes to be redeemed in accordance with Section 106 of the Indenture. In the case of a partial redemption, if the Notes to be redeemed are held
in certificated form, selection of the Notes for redemption will be made by the Trustee, by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that
relates to such Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of the original Note upon
surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes, including selection of the Notes for redemption, shall be done in accordance with the policies and
procedures of the depositary and may be made on a pro rata pass-through distribution of principal basis. The Company will not know the exact Redemption Price until approximately two (2) to three (3) Business Days before the Redemption
Date. Therefore, the notice of redemption will only describe how the Redemption Price will be calculated. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or
portions thereof called for redemption.
8.
Additional Notes
The Company may, without the consent of the Holders of the Notes, create and issue additional Notes ranking equally with the Notes in all
respects, including having the same terms (except for the price to public, the issue date and the initial interest accrual date and the first Interest Payment Date, as applicable), so that such additional Notes shall be consolidated and form a
single series with the Notes and shall have the same terms as to status, redemption or otherwise as the Notes. Such additional Notes will have the same CUSIP number as the Notes being authenticated on the date hereof, provided that such additional
Notes are part of the same issue as the Notes being authenticated on the date hereof for U.S. federal income tax purposes. If such additional Notes are not part of the same issue for U.S. federal income tax purposes, such additional Notes must be
issued with a separate CUSIP number. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.
9.
Denominations; Transfer; Exchange
The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000. A Holder may
transfer or exchange Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Security Registrar need not register the transfer or exchange of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) for a period of fifteen
(15) Business Days before a selection of Notes to be redeemed.
10.
Persons Deemed Owners
The registered Holder of this Note may be treated as the owner of it for all purposes.
11.
Unclaimed Money
If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or the Paying Agent for payment.
12.
Satisfaction and Discharge
Under the Indenture, the Company can terminate its obligations with respect to the Notes not previously delivered to the Trustee for
cancellation when those Notes have become due and payable or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving notice of
redemption. The Company may terminate its obligations with respect to the Notes by depositing with the Trustee, as funds in trust dedicated solely for that purpose, an amount sufficient to pay and discharge the entire indebtedness on the Notes. In
that case, the Indenture will cease to be of further effect and the Company’s obligations will be satisfied and discharged with respect to the Notes (except as to the Company’s obligations to pay all other amounts due under the Indenture
and to provide certain Officers’ Certificates and Opinions of Counsel to the Trustee). At the expense of the Company, the Trustee will execute proper instruments acknowledging the satisfaction and discharge.
13.
Amendment, Waiver
Subject to certain exceptions set forth in the Indenture, (i) the Indenture may be amended with the written consent of the Holders of a
majority in principal amount of the then Outstanding Securities of each series affected by such amendment, (ii) the Notes may be amended with the written consent of the Holders of at least a majority in principal amount of the Outstanding Notes
and (iii) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount of the Outstanding Notes. Subject to certain exceptions set forth in the Indenture, without the
consent of any Holder, the Company and the Trustee shall be entitled to amend the Indenture to, among other things, cure any ambiguity, defect or inconsistency, or to evidence the succession of another Person as obligor under the Indenture, or to
add to the Company’s covenants or to surrender any right or power conferred on the Company under the Indenture, or to add events of default, or to secure the Notes, or to evidence or provide for the acceptance or appointment by a successor
Trustee or facilitate the administration of the trusts under the Indenture by more than one trustee, or to conform the Indenture to any amendment of the Act.
14.
Defaults and Remedies
Under the Indenture, Events of Default include: (i) a default by the Company in the payment of any interest upon any Note and the
continuance of such default for 60 days; (ii) a default by the Company in the payment of principal of or any premium on any Note when due at Maturity, on redemption, by declaration or otherwise, and the continuance of such default for three
(3) Business Days; (iii) a default by the Company in the performance of or breach of any covenant or warranty in the Indenture and continuance of such default for 90 days after written notice has been given to the Company by the Trustee or
to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Notes; (iv) a default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company, or
the Company defaults under any mortgage, indenture or instrument under which there may be issued, secured or evidenced indebtedness constituting a failure to pay in excess of $50,000,000 of the principal or interest when due and payable, subject to
certain cure rights; or (v) certain events of bankruptcy, insolvency or reorganization involving the Company. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 33% in principal amount of the Outstanding
Notes may declare all the Notes to be due and payable immediately.
Holders may not enforce the Indenture or the Notes except as provided
in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee
in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.
15.
Trustee Dealings with the Company
Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.
16.
No Recourse Against Others
A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Notes.
17.
Authentication
This Note shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) signs the certificate of authentication
on the other side of this Note in accordance with requirements set forth in the Indenture and the Officers’ Certificate.
18.
Abbreviations
Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).
19.
CUSIP and ISIN Numbers
Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused the applicable
CUSIP number to be printed on the Notes and has directed the Trustee to use such CUSIP number in any notice of redemption as a convenience to the Holders. To the extent such number has been issued, the Company has caused the applicable ISIN number
to be similarly printed on the Notes and has similarly instructed the Trustee. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.
20.

Based on and subject to the foregoing and the exclusions, qualifications, limitations and other assumptions set forth in this opinion letter,
we are of the opinion that:

Notes.

the Agreements and the Prospectus, (ii) the Company has received the consideration provided for in the Prospectus Supplement and the Agreements, and (iii) the Notes have been authenticated in accordance with the provisions of the
Indenture, the Notes will constitute the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, under the laws of State of New York.
Matters Excluded from Our Opinions
We express no opinion with respect to the following matters:
(a) Indemnification and Change of Control. The enforceability of any agreement relating to (i) indemnification, contribution or
exculpation from costs, expenses or other liabilities or (ii) changes in the organizational control or ownership of any party, which agreement (in the case of clause (i) or clause (ii)) is contrary to public policy or Applicable Law.
(b) Jurisdiction, Venue, etc. The enforceability of any agreement to submit to the jurisdiction of any specific federal or state court
(other than the enforceability in a court of the State of New York of any such agreement to submit to the jurisdiction of a court of the State of New York), to waive any objection to the laying of the venue, to waive the defense of forum non
conveniens in any action or proceeding referred to therein, to waive trial by jury, to effect service of process in any particular manner or to establish evidentiary standards, and any agreement regarding the choice of law governing any Subject
Document (other than the enforceability in a court of the State of New York or in a federal court sitting in the State of New York and applying New York law to any such agreement that the laws of the State of New York shall govern).
(c) Remedies. The enforceability of any provision in any Subject Document to the effect that rights or remedies are not exclusive, that
every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights
or remedies will not operate as a waiver of any such right or remedy.
Qualifications and Limitations Applicable to Our Opinions
The opinions set forth above are subject to the following qualifications and limitations:
(a) Applicable Law. Our opinions are limited to the Applicable Law, and we do not express any opinion concerning any other law.
(b) Bankruptcy. Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, laws
relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors’ rights generally.
(c) Equitable Principles. Our opinions are subject to the effect of general
principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing. In applying such principles, a court, among other
things, might limit the availability of specific equitable remedies (such as injunctive relief and the remedy of specific performance), might not allow a creditor to accelerate maturity of debt or exercise other remedies upon the occurrence of a
default deemed immaterial or for non-credit reasons or might decline to order a debtor to perform covenants in a Subject Document.
(d) Unenforceability of Certain Provisions. Provisions contained in the Notes or the Subject Documents which require waivers or
amendments to be made only in writing may be unenforceable or ineffective, in whole or in part. The inclusion of such provisions, however, does not render any of the Notes or the Subject Documents invalid as a whole.
(e) Choice of New York Law and Forum. To the extent that any of our opinions relate to the enforceability of the choice of New York law
or any choice of New York forum provisions of any Subject Document, our opinion is rendered in reliance upon N.Y. Gen. Oblig. Law §§ 5-1401 and 5-1402 and N.Y.
CPLR 327(b) and is subject to the qualification that such enforceability may be limited by principles of public policy, comity and constitutionality. We express no opinion as to whether a United States federal court would have subject-matter or
personal jurisdiction over a controversy arising under the Subject Documents.
