“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.

Article II

Section 2.1      Form.

Payments of principal of, premium, if any, and interest due on the Notes representing Book-Entry Notes on any Interest Payment Date or at maturity will be made available to the Trustee by 11:00 a.m., New York City time, on such date, unless such date falls on a day which is not a Business Day, in which case such payments will be made available to the Trustee by 11:00 a.m., New York City time, on the next Business Day.

The Company shall not, nor shall it permit any of its Principal Subsidiaries to, create, assume, or incur any mortgage, lien, security interest, pledge, charge, or other encumbrance (“liens”) upon any Principal Property or upon any capital stock of any Principal Subsidiary, whether owned on the date hereof or thereafter acquired, to secure any Indebtedness of the Company or any other Person (other than the Notes), without in any such case making effective provisions whereby all of the outstanding Notes are secured equally and ratably with, or prior to, such Indebtedness so long as such Indebtedness is so secured.

Notwithstanding the foregoing, the Company may, and may permit any of its Principal Subsidiaries to, create, assume, or incur without securing the Notes (a) any Permitted Lien, (b) any lien upon any Principal Property or capital stock of a Principal Subsidiary to secure Indebtedness of the Company or any other Person, provided that the aggregate principal amount of all Indebtedness then outstanding secured by such lien and all similar liens under this clause (b), together with all Attributable Indebtedness from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by clauses (1) through (4), inclusive, of Section 5.2 hereof), does not exceed 15% of Consolidated Net Tangible Assets, or (c) any lien upon (i) any Principal Property that was not owned by the Company or any of its Subsidiaries on the date hereof or (ii) the capital stock of any Principal Subsidiary that owns no Principal Property that was owned by the Company or any of its Subsidiaries on the date hereof, in each case owned by a Subsidiary of the Company (an “Excluded Subsidiary”) that (A) is not, and is not required to be, a Subsidiary Guarantor and (B) has not granted any liens on any of its property securing Indebtedness with recourse to the Company or any Subsidiary of the Company other than such Excluded Subsidiary or any other Excluded Subsidiary.

The Company will not, and will not permit any Principal Subsidiary to, engage in the sale or transfer by the Company or any of its Principal Subsidiaries of any Principal Property to a Person (other than the Company or a Subsidiary of the Company) and the taking back by the Company or its Principal Subsidiary, as the case may be, of a lease of such Principal Property (a “Sale-Leaseback Transaction”), unless:

(1)     such Sale-Leaseback Transaction occurs within one year from the date of completion of the acquisition of the Principal Property subject thereto or the date of the completion of construction, development, or substantial repair or improvement, or commencement of full operations on such Principal Property, whichever is later;

(2)     the Sale-Leaseback Transaction involves a lease for a period, including renewals, of not more than three years;

(3)     the Company or such Principal Subsidiary would be entitled to incur Indebtedness secured by a lien on the Principal Property subject thereto in a principal amount equal to or exceeding the Attributable Indebtedness from such Sale-Leaseback Transaction without equally and ratably securing the Notes; or

(4)     the Company or such Principal Subsidiary, within a one-year period after such Sale-Leaseback Transaction, applies or causes to be applied an amount not less than the Attributable Indebtedness from such Sale-Leaseback Transaction to (a) the prepayment, repayment, redemption, reduction, or retirement of any Indebtedness of the Company or any of its Subsidiaries that is not subordinated to the Notes or any Guarantee, or (b) the expenditure or expenditures for Principal Property used or to be used in the ordinary course of business of Company or its Subsidiaries.

[REVERSE OF SECURITY]

ENLINK MIDSTREAM, LLC

5.650% SENIOR NOTES DUE 2034

This Security is one of a duly authorized issue of debentures, notes, or other evidences of indebtedness of the Company (the “Debt Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Company, the Guarantor, and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase, or analogous funds (if any) and may otherwise vary as provided in the Indenture. This Security is one of a series designated as the 5.650% Senior Notes due 2034 of the Company, in an initial aggregate principal amount of $500,000,000 (the “Securities”).

The Company promises to pay interest on the principal amount of this Security at the rate of 5.650% per annum.

The Company will pay interest semi-annually on March 1 and September 1 of each year (each an “Interest Payment Date”), commencing March 1, 2025. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from [the date of issuance]. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest (including post-petition interest in any proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the same rate per annum, in each case to the extent lawful.

The Company shall pay interest on the Securities (except Defaulted Interest) to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Any such interest not so punctually paid or duly provided for (“Defaulted Interest”) may be paid to the persons who are registered Holders at the close of business on a special record date for the payment of such Defaulted Interest, or in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may then be listed if such manner of payment shall be deemed practicable by the Trustee, as more fully provided in the Indenture. The Company shall pay principal, premium, if any, and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. Payments in respect of a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made at the office or agency of the Company maintained for such purpose in the place of payment for the notes, which initially will be at the corporate trust office of the Trustee as specified in Section 13.03 of the Indenture or such other address as to which the Trustee may give notice to the Company, or, at the option of the Company, payment of interest may be made by check mailed to the Holders on the relevant record date at their addresses set forth in the register of Holders maintained by the Registrar or at the option of the Holder, payment of interest on Securities in definitive form will be made by wire transfer of immediately available funds to any account maintained in the United States, provided such Holder has requested such method of payment and provided timely wire transfer instructions to the Paying Agent. The Holder must surrender this Security to a Paying Agent to collect payment of principal.

If any interest payment date, any Redemption Date, the applicable maturity date or any other date on which a payment on the Notes is due falls on a day that is not a Business Day, the payment due on such interest payment date, Redemption Date, maturity date or other date, as applicable, will be made on the next Business Day, and no interest will accrue on the amount of interest due on that interest payment date, Redemption Date, maturity date or other date, as applicable, for the period from and after the interest payment date, Redemption Date, maturity date or other date, as the case may be, to the date of payment.

Initially, Computershare Trust Company, N.A. will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar at any time upon notice to the Trustee and the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

This Security is one of a duly authorized issue of Debt Securities of the Company issued and to be issued in one or more series under the Indenture.

Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Base Indenture, those made part of the Indenture by reference to the TIA, as in effect on the date of the Base Indenture, and those terms stated in the First Supplemental Indenture. The Securities are subject to all such terms, and Holders of Securities are referred to the Base Indenture, the First Supplemental Indenture, and the TIA for a statement of them. The Securities of this series are general unsecured obligations of the Company limited to an initial aggregate principal amount of $500,000,000; provided, however, that the authorized aggregate principal amount of such series may be increased from time to time as provided in the First Supplemental Indenture.

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

Any redemption under the foregoing will be effected in compliance with the Article III of the Base Indenture, including with respect to notice provisions.

The Securities are to be issued in registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

The registered Holder of a Security may be treated as the owner of it for all purposes.

Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority in principal amount of the outstanding Debt Securities of each series affected. Without consent of any Holder of a Security, the parties thereto may amend or supplement the Indenture to, among other things, cure any ambiguity or omission, to correct any defect or inconsistency, or to make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

Certain events of bankruptcy or insolvency are Events of Default that will result in the principal amount of the Securities, together with premium, if any, and accrued and unpaid interest thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any other Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then outstanding may declare the principal amount of all the Securities, together with premium, if any, and accrued and unpaid interest thereon, to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after such a declaration of acceleration has been made, the Holders of a majority in aggregate principal amount of the outstanding Securities, by written notice to the Trustee, may rescind such acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction already rendered and if all existing Events of Default with respect to the Securities have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely by the declaration of acceleration. No such rescission shall affect any subsequent default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and subject to the provisions of the TIA relating to conflicts of interest and preferential claims may otherwise deal with the Company with the same rights it would have as if it were not the Trustee.

This Security shall not be valid until the Trustee signs the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

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

None of the Managing Member nor any director, officer, employee, incorporator, manager, or unitholder or other owner of equity of the Managing Member, the Company, or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Subsidiary Guarantors or the Company under the Securities, the Indenture, or any Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting the Securities, each Holder will waive and release all such liability. The waiver and release are part of the consideration for issuance of the Securities.

This Security shall be construed in accordance with and governed by the laws of the State of New York.

The Securities are fully and unconditionally guaranteed on an unsecured, unsubordinated basis by the Guarantor as set forth in Article XIV of the Base Indenture, and under certain circumstances set forth in the First Supplemental Indenture one or more Subsidiaries of the Company may be required to join in such Guarantee.

FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

This Supplemental Indenture (this “Supplemental Indenture”), dated as of           , 20          , is among            (the “Guaranteeing Subsidiary”), EnLink Midstream, LLC, a Delaware limited liability company (the “Company”), the other Guarantors (as defined in the Indenture referred to herein), and Computershare Trust Company, N.A., as trustee under the Indenture referred to below (the “Trustee”).

W I T N E S S E T H

WHEREAS, the Company has executed and delivered to the Trustee an Indenture, dated as of August 15, 2024 (the “Base Indenture”), as amended and supplemented by a First Supplemental Indenture dated as of August 15, 2024 (the “First Supplemental Indenture”), among the Company, EnLink Midstream Partners, LP, a Delaware limited partnership, as guarantor, and the Trustee (the Base Indenture, as amended and supplemented by the First Supplemental Indenture, the “Indenture”), providing for the issuance by the Company of a series of Debt Securities designated as the “5.650% Senior Notes due 2034” (the “Notes”);

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s obligations under the Notes in accordance with Article XIV of the Base Indenture and Section 3.2 of the First Supplemental Indenture and on the terms and conditions set forth herein (the “Note Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. Agreement to Guarantee. The Guaranteeing Subsidiary hereby provides the Note Guarantee on the terms and subject to the conditions set forth in the Indenture including but not limited to Article XIV of the Base Indenture.

3. No Recourse Against Others. No past, present or future director, officer, partner, member, employee, incorporator, manager or unit holder or other owner of equity interests of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture, or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Securities and Exchange Commission that such a waiver is against public policy.

4. Governing Law. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

5. Counterparts. This Supplemental Indenture shall be valid, binding, and enforceable against a party only when executed and delivered by an authorized individual on behalf of the party by means of (i) any electronic signature permitted by the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions Act, and/or any other relevant electronic signatures law, including relevant provisions of the Uniform Commercial Code (collectively, “Signature Law”); (ii) an original manual signature; or (iii) a faxed, scanned, or photocopied manual signature. Each electronic signature or faxed, scanned, or photocopied manual signature shall for all purposes have the same validity, legal effect, and admissibility in evidence as an original manual signature.

This Supplemental Indenture may be executed in any number of counterparts, each of which shall be deemed to be an original, but such counterparts shall, together, constitute one and the same instrument. For avoidance of doubt, original manual signatures shall be used for execution or indorsement of writings when required under the Uniform Commercial Code or other Signature Law due to the character or intended character of the writings.

6. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.
