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

(3) the Partnership 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 Partnership 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 Partnership 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 Partnership or its Subsidiaries.

ENLINK MIDSTREAM PARTNERS, LP

2.700% SENIOR NOTES DUE 2019

This Security is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of the Partnership (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 Partnership 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 2.700% Senior Notes due 2019 of the Partnership, in an initial aggregate principal amount of $400,000,000 (the “Securities”).

1. Interest.

The Partnership promises to pay interest on the principal amount of this Security at the rate of 2.700% per annum.

The Partnership will pay interest semi-annually on April 1 and October 1 of each year (each an “Interest Payment Date”), commencing October 1, 2014. 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 March 19, 2014. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Partnership 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.

2. Method of Payment.

The Partnership 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 Partnership 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 Partnership maintained for such purpose in New York, New York, which initially will be at the corporate trust office of the Trustee located

A-1-4

at ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Corporate Trust, or, at the option of the Partnership, 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.

3. Paying Agent and Registrar.

Initially, ▇▇▇▇▇ Fargo Bank, National Association will act as Paying Agent and Registrar. The Partnership may change any Paying Agent or Registrar at any time upon notice to the Trustee and the Holders. The Partnership may act as Paying Agent.

4. Indenture.

This Security is one of a duly authorized issue of Debt Securities of the Partnership 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 Partnership limited to an initial aggregate principal amount of $400,000,000; 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.

5. Redemption.

Prior to March 1, 2019, the Securities are redeemable, at the option of the Partnership, at any time in whole, or from time to time in part, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed that would be due after the related Redemption Date but for such redemption (exclusive of interest accrued to, but excluding, the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 20 basis points; plus, in either case, accrued and unpaid interest to, but excluding, the Redemption Date.

At any time on or after March 1, 2019, the Securities are redeemable, at the option of the Partnership, in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date.

Notices of redemption shall be sent at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Securities are to be redeemed. Unless the Partnership

A-1-5

defaults in payment of the redemption price, on and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption.

The Partnership shall deliver to the Trustee an Officers’ Certificate with respect to the actual redemption price of the Securities in connection with a redemption thereof.

Except as set forth above, the Securities will not be redeemable prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund.

6. Denominations; Transfer; Exchange.

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.

7. Person Deemed Owners.

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

8. Amendment; Supplement; Waiver.

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.

9. Defaults and Remedies.

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

A-1-6

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 reasonable 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.

10. Trustee Dealings with Partnership.

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 Partnership with the same rights it would have as if it were not the Trustee.

11. Authentication.

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

12. Abbreviations and Defined Terms.

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).

13. CUSIP Numbers.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Partnership 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.

14. Absolute Obligation.

No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Partnership, 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.

15. No Recourse.

None of the General Partner nor any director, officer, employee, incorporator, manager or unitholder or other owner of equity of the General Partner, the Partnership or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Subsidiary Guarantors or the Partnership under the Securities, the Indenture or any Guarantee or for any claim based on, in

A-1-7

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.

16. Governing Law.

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