(r) rights reserved to or vested in any municipality or public authority to control or regulate any property of the Issuer or a Subsidiary of the Issuer, or to use such property in any manner which does not materially impair the use of such property for the purposes for which it is held by the Issuer or such Subsidiary;

In the event that the Issuer or a Subsidiary of the Issuer shall hereafter secure the Notes equally and ratably with any other obligation or Indebtedness pursuant to the provision of this Section 4.10, the Trustee is hereby authorized to enter into an indenture supplemental hereto and to take such action, if any, as it may deem advisable to enable it to enforce effectively the rights of the Holders of the Notes so secured, equally and ratably with such other obligation or Indebtedness.

The Trustee, at its request, shall be provided with an Opinion of Counsel as conclusive evidence that any such supplemental indenture or steps taken to secure the Notes equally and ratably comply with the provisions of this Section 4.10.

Section 4.11 Limitations on Sale and Lease-Back Transactions. The Issuer will not, and will not permit any of its Subsidiaries to, enter into any arrangement with any Person providing for the lease by the Issuer or a Subsidiary of the Issuer of any Principal Property, acquired or placed into service more than 180 days prior to such arrangement (except for leases of three years or less), whereby such property has been or is to be sold or transferred by the Issuer or any Subsidiary of the Issuer to such Person (herein referred to as a “Sale and Lease-Back Transaction”), unless:

(a) the Issuer or such Subsidiary would, at the time of entering into a Sale and Lease-Back Transaction, be entitled to incur Indebtedness secured by a mortgage on such Principal Property to be leased in a principal amount at least equal to the Attributable Debt in respect of such transaction without equally and ratably securing the Notes pursuant to Section 4.10 hereof; or

(b) the Issuer shall covenant that it will apply an amount equal to the net proceeds from the sale of the Principal Property so leased to the retirement (other than any mandatory retirement) of its Funded Indebtedness within 90 days of the effective date of any such Sale and Lease-Back Transaction, provided that the amount to be applied to the retirement of Funded Indebtedness of the Issuer shall be reduced by (i) the principal amount of any Notes delivered by the Issuer to the Trustee within 90 days after such Sale and Lease-Back Transaction for retirement and cancellation, and (ii) the

-8-

principal amount of Funded Indebtedness, other than Notes, voluntarily retired by the Issuer within 90 days following such Sale and Lease-Back Transaction, and provided, further, that the covenant contained in this Section 4.11 shall not apply to, and there shall be excluded from Attributable Debt in any computation under this Section 4.11, Attributable Debt with respect to any Sale and Lease-Back Transaction if:

(A) such Sale and Lease-Back Transaction is entered into in connection with transactions which are part of an industrial development or pollution control financing, or

(B) the only parties involved in such Sale and Lease-Back Transaction are the Issuer and any Subsidiary or Subsidiaries of the Issuer.

Notwithstanding these restrictions on Sale and Lease-Back Transactions, the Issuer and its Subsidiaries may enter into, create, assume and suffer to exist Sale and Lease-Back Transactions, not otherwise permitted hereby, if at the time of, and after giving effect to, such Sale and Lease-Back Transactions, the total consolidated Attributable Debt of the Issuer and its Subsidiaries in respect of such Sale and Lease-Back Transactions, together with mortgages incurred pursuant to Section 4.10(y) hereof, does not exceed 10% of Consolidated Net Tangible Assets of the Issuer.”

ARTICLE VI

ADDITIONAL AMENDMENTS TO THE BASE INDENTURE

Section 6.01 Amendment to Section 11.02(b). Only in relation to the Notes, the first paragraph of Section 11.02(b) of the Base Indenture is hereby amended and restated in its entirety to read as follows:

“(b) Subject to Sections 11.02(c), 11.03 and 11.07, the Partnership at any time may terminate, with respect to Debt Securities of a particular series, all its obligations under the Debt Securities of such series and this Indenture with respect to the Debt Securities of such series (“legal defeasance option”) or the operation of: (i) Article X; (ii) any covenant made applicable to such Debt Securities pursuant to Section 2.03; (iii) Sections 6.01(d), (g) and (h) (including, without limitation, all Events of Default added pursuant to Article VI of the Eighth Supplemental Indenture); and (iv) as they relate to the Guarantors only, Sections 6.01(e) and (f) (“covenant defeasance option”). If the Partnership exercises either its legal defeasance option or its covenant defeasance option with respect to Debt Securities of a particular series that are entitled to the benefit of the Guarantee, the Guarantee will terminate with respect to that series of Debt Securities. The Partnership may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.”

Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the February 1 or August 1 next preceding the Interest Payment Date, even if such Notes are canceled

²	To be included only if the Note is issued in global form.

Exhibit A-3

after such record date and on or before such Interest Payment Date, except as provided in Section 2.16 of the Base Indenture with respect to Defaulted Interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a paying agent on or after the Stated Maturity thereof. The Notes shall be payable as to principal, premium, if any, and interest at the office or agency of the Trustee maintained for such purpose (which initially is 0 Xxxxx XxXxxxx Xxxxxx, Xxxxx 000, Xxxxxxx, Xxxxxxxx 60602), or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Debt Security Register or by wire transfer to accounts designated by the Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, and interest and premium, if any, on each Global Security. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, shall act as paying agent and Registrar. The Issuer may change any paying agent or Registrar without notice to any Holder. The Partnership may act in any such capacity.

4. Indenture. The Issuer issued the Notes under an Indenture dated as of August 21, 2009 (the “Original Indenture”), as amended by the Third Supplemental Indenture thereto dated as of April 18, 2013 (the Original Indenture, as so amended, the “Base Indenture”), as amended and supplemented by the Eighth Supplemental Indenture, dated as of August 11, 2020 (the “Eighth Supplemental Indenture,” and, together with the Base Indenture, the “Indenture”), each between the Issuer, Boardwalk Pipeline Partners, LP, as guarantor (together with its successors, the “Guarantor”), and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are the obligation of the Issuer and the Guarantor, initially in aggregate principal amount of $500 million. The Issuer may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued and Outstanding Notes (and as the same series (with identical terms other than with respect to the issue date, issue price and first payment of interest) as the initial Notes for the purposes indicated in Section 3.02 of the Eighth Supplemental Indenture).

5. Optional Redemption.

(a) At its option, the Issuer at any time prior to the Par Call Date, may choose to redeem all or any portion of the Notes, at once or from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of such Notes and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon that would have been due if the Notes matured on the Par Call Date (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 45 basis points, plus in each case accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

Exhibit A-4

For purposes of determining the redemption price, the following definitions shall apply:

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed (assuming, for this purpose, that the Notes matured on the Par Call Date (the “Remaining Life”)) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the Remaining Life of the Notes to be redeemed (including, with respect to the definition of the term “Remaining Life”).

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations or (2) if the Issuer obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Issuer.

“Par Call Date” means November 15, 2030.

“Reference Treasury Dealers” means each of Barclays Capital Inc., X.X. Xxxxxx Securities LLC, Mizuho Securities USA LLC and a Primary Treasury Dealer (as defined below) selected by MUFG Securities Americas Inc., or an affiliate or successor of the foregoing, and one Primary Treasury Dealer selected by the Issuer; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Issuer by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding such Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

Exhibit A-5

6. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase them at the option of the Holders.

7. Notice of Redemption. Notice of redemption shall be mailed by first class mail (or, in the case of Global Securities, transmitted electronically) at least 10 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notices of redemption may be subject to conditions, as provided in the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the redemption price has been paid.

8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay any taxes or other governmental charges imposed in relation thereto.

9. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes, and any existing default or compliance with any provision of the Indenture relating to the Notes may be waived with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder of a Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 9.01 of the Indenture.

11. Defaults and Remedies. If any Event of Default, other than one arising from certain events of bankruptcy or insolvency as described in the Indenture, occurs and is continuing, then, unless the principal of and accrued and unpaid interest on all the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal of and interest on all the Notes to be due and payable. In the case of an Event of Default arising from certain events of bankruptcy or insolvency, then in each and every such case, unless the principal of and accrued and unpaid interest on all the Notes shall have already become due and payable, the principal of and interest on all the Notes shall become due and payable immediately, without further action or notice.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if the Trustee determines in good faith that withholding notice is in the Holders’ interests. The Holders of not less than a majority

Exhibit A-6

in aggregate principal amount of the Notes then Outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default or Event of Default and its consequences under the Indenture except a Default or Event of Default in the payment of interest on, the principal of, or premium, if any, on, the Notes or an Event of Default relating to a provision of the Indenture that cannot be amended without the consent of each Holder affected thereby. The Partnership is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Partnership is required within 30 days after it becomes aware of the occurrence of any Default or Event of Default to deliver to the Trustee a statement specifying such Default or Event of Default and certain additional information.

14. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP and corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and corresponding ISIN numbers in notices of redemption as a convenience to Holders. 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.
