CERC SUBORDINATED GUARANTEE 

Section 3.01 Subordinated Guarantee of Collection. CenterPoint Energy Resources Corp. shall be a Guarantor of the 2019
Notes and 2024 Notes (the “Guaranteed Notes”) in accordance with Section 1602 of the Original Indenture. The Guarantor guarantees (the “Subordinated Guarantee of Collection”) to the Trustee, for the ratable
benefit of the Holders of the Guaranteed Notes, the full and prompt collection of the Company’s obligations under the Guaranteed Notes (each Holder, a “Guaranteed Party” and, collectively, the “Guaranteed
Parties”) and the Company’s obligations under the Indenture with respect to the Guaranteed Notes (the “Guaranteed Obligations”). Such Subordinated Guarantee of Collection is a guaranty of collection only, and not a
guaranty of payment.  
 Section 3.02 Exhaustion of Other Remedies Required. The obligations of the Guarantor hereunder
are those of a secondary obligor, and not as primary obligor, and are dependent, in all respects, upon the Trustee, on behalf of the Guaranteed Parties, first pursuing and exhausting all rights and remedies, both legal and equitable, against the
Company to collect payment upon the Guaranteed Obligations. 
 Section 3.03 Guaranteed Obligations Absolute. Except as otherwise
provided in this First Supplemental Indenture, the Guarantor’s obligations under the Subordinated Guarantee of Collection are in all respects absolute and unconditional and shall not be impaired, modified, released or limited by any occurrence
or condition whatsoever, including, without limitation: (i) any amendment to, restatement of, supplement to or other modification of the Indenture in accordance with the terms thereof, or any furnishing, acceptance or release of any collateral
for the Guaranteed Obligations or the addition, substitution or release of any other guarantor or any other entity or other Person primarily or secondarily liable in respect of the Guaranteed Obligations, (ii) any waiver, consent, extension,
indulgence or other action or inaction under or in respect of the Indenture, (iii) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or its
property, (iv) any merger, amalgamation or consolidation of any other guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of any other guarantor or of the Company to any Person or
(v) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense (other than repayment in full in cash of all the Guaranteed Obligations) of a guarantor (whether or not similar to the foregoing).

 Section 3.04 Subordination. 

(a) Any payment in respect of the Guaranteed Obligations is subordinated, to the extent and in the manner provided in this
Section 3.04, to the prior payment in full of all CERC Senior Debt, whether outstanding at the date of this First Supplemental Indenture or thereafter created, incurred, assumed or guaranteed. These subordination provisions are for the benefit
of the holders of CERC Senior Debt. This Section 3.04 shall constitute a continuing offer to all Persons who, in reliance upon such provisions, become holders of, or continue to hold, CERC Senior Debt, and such provisions are made for the
benefit of the holders of CERC Senior Debt, and such holders are made obligees hereunder and any one or more of them may enforce such provisions. 

  
 16 








 (b) (i) No payment shall be made by or on behalf of the Guarantor on account
of any of the Guaranteed Obligations in the event of default in payment of any principal of, premium (if any) or interest on any CERC Senior Debt when the same becomes due and payable, whether at maturity or at a date fixed for prepayment or by
acceleration of maturity or otherwise (a “Payment Default”), unless and until such Payment Default has been cured or waived or otherwise has ceased to exist or such CERC Senior Debt has been discharged or paid in full. 

(ii) No payment shall be made by or on behalf of the Guarantor on account of any of the Guaranteed Obligations in the event of
any event of default (other than a Payment Default) with respect to any Designated CERC Senior Debt permitting the holders of such Designated CERC Senior Debt (or a trustee, agent or other representative on behalf of the holders thereof) to declare
such Designated CERC Senior Debt due and payable prior to the date on which it would otherwise have become due and payable, upon written notice thereof to the Guarantor and the Trustee by any holders of Designated CERC Senior Debt (or a trustee,
agent or other representative on behalf of the holders thereof) (a “Payment Blocking Notice”), unless and until such event of default has been cured or waived or otherwise has ceased to exist or such Designated CERC Senior Debt has
been discharged or paid in full, provided, that such payments may not be prevented pursuant to this Section 3.04(b)(ii) for more than 179 days after an applicable Payment Blocking Notice has been received by the Trustee unless the Designated
CERC Senior Debt in respect of which such event of default exists has been declared due and payable in its entirety, in which case no such payment may be made until such acceleration has been rescinded or annulled or such Designated CERC Senior Debt
has been discharged or paid in full. No event of default that existed or was continuing on the date of any Payment Blocking Notice may be made the basis for the giving of a second Payment Blocking Notice, and only one such Payment Blocking Notice
may be given in any 360-day period, irrespective of the number of defaults with respect to any number of issues of Designated CERC Senior Debt during such period. 

(iii) In furtherance of the provisions of Section 3.04(a) of this First Supplemental Indenture, in the event that,
notwithstanding the foregoing provisions of this Section 3.04(b), any payment or distribution of assets of the Guarantor shall be received by the Trustee for the benefit of any Guaranteed Party at a time when such payment or distribution was
prohibited by the provisions of this Section 3.04(b) and the Trustee has received notice from the Guarantor or the Company that such payment or distribution was prohibited by the provisions of this Section 3.04(b), then, unless such
payment or distribution has thereafter been paid or distributed by the Trustee or Paying Agent to the Guaranteed Party or is no longer prohibited by this Section 3.04(b), such payment or distribution shall be held in trust by the Trustee for
the benefit of the holders of CERC Senior Debt, and upon direction from the Guarantor or the Company shall be paid or delivered by the Trustee to the holders of CERC Senior Debt remaining unpaid or unprovided for or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such CERC Senior Debt may have been issued, it being understood that such payment or delivery shall be made ratably, according to the
aggregate amounts remaining unpaid on account of such CERC Senior Debt held or represented by each, for application to the payment of all CERC Senior Debt in full after giving effect to all concurrent payments and distributions to or for the holders
of such CERC Senior Debt. 
 (c) Upon any distribution of assets of the Guarantor or upon any dissolution, winding up, total
or partial liquidation or reorganization of the Guarantor, whether voluntary or involuntary, in bankruptcy, insolvency, receivership or similar proceedings or upon any assignment for the benefit of creditors:

Guaranteed Party is entitled to receive any payment on account of the Guaranteed Obligations; 
 (ii) any payment or
distribution of assets of the Guarantor of any kind or character, whether in cash, property or securities, to which any Guaranteed Party would be entitled, except for the provisions of this Section 3.04, shall be paid by the liquidating trustee
or agent or other Person making such a payment or distribution directly to the holders of such CERC Senior Debt or their representative, ratably according to the respective amounts of CERC Senior Debt held or represented by each, to the extent
necessary to make payment in full of all such CERC Senior Debt remaining unpaid after giving effect to all concurrent payments and distributions to the holders of such CERC Senior Debt; 

  
 17 








 (iii) in the event that, notwithstanding the foregoing provisions of this
Section 3.04(c), (A) any payment or distribution of assets of the Guarantor of any kind or character, whether in cash, property or securities, shall be received by the Trustee for the benefit of any Guaranteed Party on account of any of
the Guaranteed Obligations before all CERC Senior Debt is paid in full, (B) any holder of such CERC Senior Debt, notifies the Trustee of the amounts then due and owing on such CERC Senior Debt, if any, held by such holder (which notice shall be
provided as promptly as practical following notice from the Guarantor or the Company or the liquidating trustee or agent to the holders of such CERC Senior Debt that such prohibited payment has been received by the Trustee), and (C) such
payment or distribution has not thereafter been paid or distributed by the Trustee or Paying Agent to the Guaranteed Party, then such payment or distribution shall be received and held in trust by the Trustee for the benefit of the holders of such

remaining unpaid after giving effect to all concurrent payments and distributions and all provisions therefor to or for the holders of such CERC Senior Debt, and upon direction from the Guarantor or the Company, the Trustee shall pay only the

of assets of the Guarantor applicable to the CERC Senior Debt until release and discharge of the Subordinated Guarantee of Collection in accordance with Section 3.06 of this First Supplemental Indenture. For the purpose of such subrogation, no
such payments or distributions to the holders of such CERC Senior Debt by the Guarantor or by or on behalf of the Guaranteed Parties by virtue of this Section 3.04, which otherwise would have been made to such Guaranteed Parties shall, as
between the Guarantor and such Guaranteed Parties, be deemed to be payment by the Guarantor on account of such CERC Senior Debt, it being understood that the provisions of this Section 3.04 are, and are intended, solely for the purpose of
defining the relative rights of the Guaranteed Parties, on the one hand, and the holders of such CERC Senior Debt, on the other hand. 

(ii) If any payment or distribution to which any Guaranteed Party would otherwise have been entitled but for the provisions of
this Section 3.04 shall have been applied, pursuant to the provisions of this Section 3.04, to the payment of amounts payable under CERC Senior Debt, then the Trustee, on behalf of such Guaranteed Party, shall be entitled to receive from
the holders of such CERC Senior Debt any payments or distributions received by such holders of CERC Senior Debt in excess of the amount sufficient to pay all amounts payable under or in respect of such CERC Senior Debt in full and such amounts shall
be paid and distributed by the Trustee or Paying Agent to the Guaranteed Party in accordance with the terms of the Indenture. 

Section 3.05 Reinstatement. This Subordinated Guarantee of Collection shall continue to be effective, or be reinstated, as the
case may be, if and to the extent at any time payment, in whole or in part, of any of the sums due to any Guaranteed Party on account of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by the Trustee upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other guarantors, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Company
or any other guarantors or any part of its or their property, or otherwise, all as though such payments had not been made.

Guaranteed Parties hereunder shall be automatically and unconditionally released and discharged upon the earliest to occur of (a) a defeasance or covenant defeasance applicable to the Guaranteed Notes in accordance with Article Four of the
Original Indenture, (b) the Company’s obligations under the Indenture with respect to the Guaranteed Notes are satisfied and discharged in accordance with the terms of the Indenture and (c) May 1, 2016.

 [REVERSE OF NOTE] 

ENABLE MIDSTREAM PARTNERS, LP 

2.400% Senior Note due 2019 

This Security is one of a duly authorized issue of senior securities of the Company (the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of May 27, 2014 (such Indenture, as amended and supplemented being referred to herein as the “Indenture”), between the Company and U.S. Bank National Association, as
trustee (the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture thereto dated as of May 27, 2014, by and among the Company, the Guarantor
and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Guarantor, the
Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used but not defined herein have the meanings set forth in the Indenture. This Security is one of
the series designated on the face hereof, initially limited in aggregate principal amount to $            . To the extent any provision of this Security conflicts with the express
provisions of the Indenture, the Indenture shall govern and be controlling. The Company may issue an unlimited aggregate principal amount of additional Securities of this series under the Indenture. Any such additional Securities shall be treated as
issued and outstanding Securities of the same series as this Security (with identical terms other than with respect to the issue date, the date of first payment of interest, if applicable, and the payment of interest accruing prior to the issue
date) for all purposes of the Indenture, including waivers, amendments, and redemptions. 
 This Security is the general, unsecured, senior
obligation of the Company and is guaranteed pursuant to a guarantee (the “Subordinated Guarantee of Collection”) by the Guarantor. The Subordinated Guarantee of Collection is an unsecured subordinated obligation of the Guarantor and
is subject to automatic release. 
 At any time prior to April 15, 2019, this Security is redeemable, in whole or in part, at the
option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of this Security to be redeemed and (ii) the sum of the present values of the principal amount of this Security to be redeemed and the
remaining scheduled payments of interest hereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled payment dates to the Redemption Date
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to, but not including,
such Redemption Date. From and after April 15, 2019, this Security is redeemable, in whole or in part, at the option of the Company, at a Redemption Price equal to 100% of the principal amount of this Security to be redeemed, plus accrued and
unpaid interest, if any, on the principal amount being redeemed to, but not including, such Redemption Date. 
 For purposes of determining
any Redemption Price, the following definitions shall apply: 
 “Comparable Treasury Issue” means the United States
Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (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 comparable maturity to the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, (a) the average of five Reference Treasury
Dealer Quotations for such Redemption Date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (b) if the Quotation Agent obtains fewer than five such Reference Treasury Dealer Quotations, the average of
all such quotations. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means (a) RBS Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated,
Credit Suisse Securities (USA) LLC and RBC Capital Markets, LLC, and their respective successors; provided, however, that if any of the foregoing ceases to be a U.S. government securities dealer (a “Primary Treasury Dealer”),
the Company shall substitute therefor another Primary Treasury Dealer and (b) one other Primary Treasury Dealer selected by the Company. 

  
 A-1-1 








 “Reference Treasury Dealer Quotations” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, 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
Quotation Agent by such Reference Treasury Dealer at 5:00 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 year equal to the semiannual 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. The Treasury Rate shall be
calculated on the third Business Day preceding any Redemption Date. 
 Unless the Company defaults in payment of the Redemption Price, on
and after the Redemption Date, interest shall cease to accrue on this Security or the portions hereof called for redemption. 
 In the event
of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 

The Company is not required to make mandatory redemption or sinking fund payments with respect to this Security. 

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of this Security or (b) certain
restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, the Guarantor and any other Guarantor, and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company, the Guarantor or any other Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company, the
Guarantor or any other Guarantor with certain provisions of the Indenture and certain existing and past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, regardless of whether notation of such consent or waiver is made upon this
Security. 
 No Holder of this Security shall have any right to institute any proceeding, judicial or otherwise, with respect to the
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of this
series, (b) as set forth in the Indenture, the Holders of not less than 25% of the principal amount of the Outstanding Securities of this series shall have made written request to the Trustee to institute proceedings in respect of certain
Events of Default set forth in the Indenture in its own name as Trustee hereunder, (c) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in
compliance with such request, (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding and (e) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of not less than a majority in 

  
 A-1-2 








 
aggregate principal amount of the Outstanding Securities of this series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatsoever by
virtue of, or by availing of, any provision of the Indenture or this Security to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to
enforce any right under the Indenture, except in the manner herein provided or provided in the Indenture and for the equal and ratable benefit of all such Holders. 

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

The Securities of this series are issuable only in registered form without coupons in denominations of U.S. $2,000 and any integral multiple
of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a
different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) payable in connection therewith, other
than exchanges pursuant to Sections 304, 306, 906 and 1107 of the Indenture. 
 Except as provided in the Indenture, prior to due
presentment of this Security for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security is overdue, and none of the Company, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary. 

No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in this Security, or the
Subordinated Guarantee of Collection endorsed thereon, or for any claim based thereon or otherwise in respect thereof, or in any Security or in the Subordinated Guarantee of Collection, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, shareholder, partner, member, officer, manager or director, as such, past, present or future, of the Company or the Guarantor or of any successor Person, either directly or through the Company or the
Guarantor or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and
released by the acceptance hereof and as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities. 

This Security shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made or
instruments entered into and, in each case, performed in said State.

ENABLE MIDSTREAM PARTNERS, LP 

3.900% Senior Note due 2024 

This Security is one of a duly authorized issue of senior securities of the Company (the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of May 27, 2014 (such Indenture, as amended and supplemented being referred to herein as the “Indenture”), between the Company and U.S. Bank National Association, as
trustee (the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture thereto dated as of May 27, 2014, by and among the Company, the Guarantor
and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Guarantor, the
Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used but not defined herein have the meanings set forth in the Indenture. This Security is one of
the series designated on the face hereof, initially limited in aggregate principal amount to $            . To the extent any provision of this Security conflicts with the express
provisions of the Indenture, the Indenture shall govern and be controlling. The Company may issue an unlimited aggregate principal amount of additional Securities of this series under the Indenture. Any such additional Securities shall be treated as
issued and outstanding Securities of the same series as this Security (with identical terms other than with respect to the issue date, the date of first payment of interest, if applicable, and the payment of interest accruing prior to the issue
date) for all purposes of the Indenture, including waivers, amendments, and redemptions. 
 This Security is the general, unsecured, senior
obligation of the Company and is guaranteed pursuant to a guarantee (the “Subordinated Guarantee of Collection”) by the Guarantor. The Subordinated Guarantee of Collection is an unsecured subordinated obligation of the Guarantor and
is subject to automatic release. 
 At any time prior to February 15, 2024, this Security is redeemable, in whole or in part, at the
option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of this Security to be redeemed and (ii) the sum of the present values of the principal amount of this Security to be redeemed and the
remaining scheduled payments of interest hereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled payment dates to the Redemption Date
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to, but not including,
such Redemption Date. From and after February 15, 2024, this Security is redeemable, in whole or in part, at the option of the Company, at a Redemption Price equal to 100% of the principal amount of this Security to be redeemed, plus accrued
and unpaid interest, if any, on the principal amount being redeemed to, but not including, such Redemption Date. 
 For purposes of
determining any Redemption Price, the following definitions shall apply: 
 “Comparable Treasury Issue” means the United
States Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (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 comparable maturity to the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, (a) the average of five Reference Treasury
Dealer Quotations for such Redemption Date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (b) if the Quotation Agent obtains fewer than five such Reference Treasury Dealer Quotations, the average of
all such quotations. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means (a) RBS Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated,
Credit Suisse Securities (USA) LLC and RBC Capital Markets, LLC, and their respective successors; provided, however, that if any of the foregoing ceases to be a U.S. government securities dealer (a “Primary Treasury Dealer”),
the Company shall substitute therefor another Primary Treasury Dealer and (b) one other Primary Treasury Dealer selected by the Company. 

  
 A-2 - 1 








 “Reference Treasury Dealer Quotations” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, 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
Quotation Agent by such Reference Treasury Dealer at 5:00 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 year equal to the semiannual 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. The Treasury Rate shall be
calculated on the third Business Day preceding any Redemption Date. 
 Unless the Company defaults in payment of the Redemption Price, on
and after the Redemption Date, interest shall cease to accrue on this Security or the portions hereof called for redemption. 
 In the event
of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 

The Company is not required to make mandatory redemption or sinking fund payments with respect to this Security. 

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of this Security or (b) certain
restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, the Guarantor and any other Guarantor, and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company, the Guarantor or any other Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company, the
Guarantor or any other Guarantor with certain provisions of the Indenture and certain existing and past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, regardless of whether notation of such consent or waiver is made upon this
Security. 
 No Holder of this Security shall have any right to institute any proceeding, judicial or otherwise, with respect to the
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of this
series, (b) as set forth in the Indenture, the Holders of not less than 25% of the principal amount of the Outstanding Securities of this series shall have made written request to the Trustee to institute proceedings in respect of certain
Events of Default set forth in the Indenture in its own name as Trustee hereunder, (c) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in
compliance with such request, (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding and (e) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of not less than a majority in 

  
 A-2 - 2 








 
aggregate principal amount of the Outstanding Securities of this series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatsoever by
virtue of, or by availing of, any provision of the Indenture or this Security to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to
enforce any right under the Indenture, except in the manner herein provided or provided in the Indenture and for the equal and ratable benefit of all such Holders. 

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

The Securities of this series are issuable only in registered form without coupons in denominations of U.S. $2,000 and any integral multiple
of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a
different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) payable in connection therewith, other
than exchanges pursuant to Sections 304, 306, 906 and 1107 of the Indenture. 
 Except as provided in the Indenture, prior to due
presentment of this Security for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security is overdue, and none of the Company, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary. 

No recourse under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in this Security, or the
Subordinated Guarantee of Collection endorsed thereon, or for any claim based thereon or otherwise in respect thereof, or in any Security or in the Subordinated Guarantee of Collection, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, shareholder, partner, member, officer, manager or director, as such, past, present or future, of the Company or the Guarantor or of any successor Person, either directly or through the Company or the
Guarantor or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and
released by the acceptance hereof and as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities. 

This Security shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made or
instruments entered into and, in each case, performed in said State.

ENABLE MIDSTREAM PARTNERS, LP 

5.000% Senior Note due 2044 

This Security is one of a duly authorized issue of senior securities of the Company (the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of May 27, 2014 (such Indenture, as amended and supplemented being referred to herein as the “Indenture”), between the Company and U.S. Bank National Association, as
trustee (the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture thereto dated as of May 27, 2014, by and among the Company, CERC and the
Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, CERC, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used but not defined herein have the meanings set forth in the Indenture. This Security is one of the series
designated on the face hereof, initially limited in aggregate principal amount to $            . To the extent any provision of this Security conflicts with the express provisions of the
Indenture, the Indenture shall govern and be controlling. The Company may issue an unlimited aggregate principal amount of additional Securities of this series under the Indenture. Any such additional Securities shall be treated as issued and
outstanding Securities of the same series as this Security (with identical terms other than with respect to the issue date, the date of first payment of interest, if applicable, and the payment of interest accruing prior to the issue date) for all
purposes of the Indenture, including waivers, amendments, and redemptions. 
 At any time prior to November 15, 2043, this Security is
redeemable, in whole or in part, at the option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of this Security to be redeemed and (ii) the sum of the present values of the principal amount of
this Security to be redeemed and the remaining scheduled payments of interest hereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount
being redeemed to, but not including, such Redemption Date. From and after November 15, 2043, this Security is redeemable, in whole or in part, at the option of the Company, at a Redemption Price equal to 100% of the principal amount of this
Security to be redeemed, plus accrued and unpaid interest, if any, on the principal amount being redeemed to, but not including, such Redemption Date. 

For purposes of determining any Redemption Price, the following definitions shall apply: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity
comparable to the term between the Redemption Date and the Stated Maturity (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 comparable maturity to the Remaining Life. 
 “Comparable Treasury Price” means, with respect
to any Redemption Date, (a) the average of five Reference Treasury Dealer Quotations for such Redemption Date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (b) if the Quotation Agent obtains
fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Quotation Agent” means
the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury Dealer” means (a) RBS Securities Inc.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, Credit Suisse Securities (USA) LLC and RBC Capital Markets, LLC, and their respective successors; provided, however, that if any of the foregoing ceases to be a U.S. government securities
dealer (a “ Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer and (b) one other Primary Treasury Dealer selected by the Company. 

  
 A-3 - 1 








 “Reference Treasury Dealer Quotations” means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, 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
Quotation Agent by such Reference Treasury Dealer at 5:00 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 year equal to the semiannual 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. The Treasury Rate shall be
calculated on the third Business Day preceding any Redemption Date. 
 Unless the Company defaults in payment of the Redemption Price, on
and after the Redemption Date, interest shall cease to accrue on this Security or the portions hereof called for redemption. 
 In the event
of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 

The Company is not required to make mandatory redemption or sinking fund payments with respect to this Security. 

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of this Security or (b) certain
restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, the Guarantor and any other Guarantor, and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company, the Guarantor or any other Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company, the
Guarantor or any other Guarantor with certain provisions of the Indenture and certain existing and past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, regardless of whether notation of such consent or waiver is made upon this
Security. 
 No Holder of this Security shall have any right to institute any proceeding, judicial or otherwise, with respect to the
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of this
series, (b) as set forth in the Indenture, the Holders of not less than 25% of the principal amount of the Outstanding Securities of this series shall have made written request to the Trustee to institute proceedings in respect of certain
Events of Default set forth in the Indenture in its own name as Trustee hereunder, (c) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in
compliance with such request, (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding and (e) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of this series; it being understood and intended that no one or more of such Holders shall have any
right in any manner whatsoever by virtue of, or by availing of, any provision of the Indenture or this Security to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over
any other of such Holders or to enforce any right under the Indenture, except in the manner herein provided or provided in the Indenture and for the equal and ratable benefit of all such Holders. 

  
 A-3 - 2 








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

The Securities of this series are issuable only in registered form without coupons in denominations of U.S. $2,000 and any integral multiple
of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a
different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) payable in connection therewith, other
than exchanges pursuant to Sections 304, 306, 906 and 1107 of the Indenture. 
 Except as provided in the Indenture, prior to due
presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this
Security is overdue, and none of the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse
under or upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in this Security, or for any claim based thereon or otherwise in respect thereof, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator, shareholder, partner, member, officer, manager or director, as such, past, present or future, of the Company or of any successor Person, either directly or through the Company
or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released by
the acceptance hereof and as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities. 

This Security shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made or
instruments entered into and, in each case, performed in said State.
