 CENTERPOINT ENERGY RESOURCES
CORP. 
 1111 Louisiana Street 

Houston, Texas 77002 
 $10,000,000
4.25% SENIOR NOTES, SERIES B, DUE JUNE 5, 2043 

May 27, 2022 
 TO
EACH OF THE PURCHASERS LISTED IN 

SCHEDULE A HERETO: 

Ladies and Gentlemen: 

CenterPoint Energy Resources Corp., a Delaware corporation (the “Company”), agrees with each of the purchasers listed in
Schedule A hereto (each, a “Purchaser” and, collectively, the “Purchasers”) as follows: 

SECTION 1 AUTHORIZATION OF ORIGINAL NOTES; RECITALS. 

Pursuant to a Note Purchase Agreement dated as of December 20, 2012 (the “Original Note Purchase Agreement”) among
Vectren Utility Holdings, Inc., an Indiana corporation (“VUHI”) as original issuer, Indiana Gas Company, Inc., an Indiana corporation (“Indiana Gas”) as guarantor, Southern Indiana Gas and Electric Company, an
Indiana corporation (“SIGECO”) as guarantor, and Vectren Energy Delivery of Ohio, Inc., an Ohio corporation (“VEDO”) as guarantor, and certain institutional investors named therein, VUHI heretofore issued and sold
(i) $45,000,000 aggregate principal amount of its 3.20% Senior Guaranteed Notes, Series A, due June 5, 2028 (the “Series A Notes”) and (ii) $80,000,000 aggregate principal amount of its 4.25% Senior Guaranteed Notes,
Series B, due June 5, 2043 (the “Series B Notes” and together with the Series A Notes, the “Original Notes”) to such institutional investors. Capitalized terms used herein without definition are used as defined
in Schedule A to this Agreement; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement. 

On February 1, 2019 CenterPoint Energy, Inc. (“CenterPoint”) acquired Vectren Corp. (“Vectren”), who is
the owner of VUHI, who in turn owns SIGECO, Indiana Gas and VEDO. In connection with such acquisition, VUHI made a Change of Control prepayment offer to the holders of the Original Notes (“Original Notes Holders”) and certain
Original Notes Holders accepted such offer. As a result of such prepayment, $10,000,000 of the Series B Notes remaining outstanding and all other Original Notes were prepaid. VUHI also has previously issued certain other VUHI Senior Notes. 

The Company is an indirect, wholly owned Subsidiary of CenterPoint. CenterPoint has proposed a restructuring (collectively referred to herein
as the “Restructuring”) wherein VUHI would still be the parent of SIGECO, but IGAS and VEDO would no longer be Subsidiaries of VUHI and instead would be Subsidiaries of the Company. After the Restructuring, each of
the Company and VUHI would be direct or indirect wholly owned Subsidiaries of Utility Holding, LLC. The proposed restructuring requires the consent of 51% of the outstanding principal amount of the Original Notes. 

 













			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 VUHI, the Company and the Original Notes Holders party to this Agreement (who, as of the date
of this Agreement, hold 100% of the outstanding principal amount of the Original Notes) desire that (i) the Original Notes Holders consent to the Restructuring, (ii) the Company enter into this Agreement and issue the Notes pursuant to the
terms hereof to the Original Notes Holders in exchange for their respective Original Notes, with such Original Notes to be delivered to the Company and (iii) VUHI, SIGECO, IGAS and VEDO are concurrently released from all obligations under the
Original Note Purchase Agreement and the Original Notes.

payable to the same holders (or their nominees). The Notes shall bear interest at the same rate, shall have the same maturity and the same semi-annual payments of interest and payments of principal as the
Original Notes and shall be dated the Effective Date. In accordance with Section 4.4, VUHI shall pay each Purchaser interest on the Original Notes held by such holder for the period from the date of the last interest payment on the Original
Notes to, but excluding, the Effective Date. The Original Notes originally issued by VUHI shall be deemed transferred to the Company on the Effective Date. 

Section 2.2. Release. Upon satisfaction of the conditions set forth in Sections 3 and 4 hereof,
effective upon the Effective Date and issuance of Notes as set forth in Section 2.1 above, VUHI, SIGECO, VEDO and Indiana Gas are hereby released from all rights and obligations under the Original Note Purchase Agreement and the Original Notes
(the “Release”). 
 Section 2.3. Indemnification. The Company shall pay, indemnify and
save harmless each Purchaser from and against any and all liabilities, costs and expenses, claims, demands or judgments arising from or out of the assumption by the Company of the obligations of VUHI under the Original Notes and the Original Note
Purchase Agreement, including, without limitation, any income tax owed by the Purchaser as a result of the issuance of new Notes by the Company in exchange for the Original Notes originally issued by VUHI constituting a taxable event for income tax
purposes. The indemnification contained in this Section 2.3 shall survive the payment or transfer of any Original Note and the termination of the Note Purchase Agreement. 

Section 2.4. Consent. Upon satisfaction of the conditions set forth in Sections 2, 3, 4 and 5 hereof,
the Purchaser, as evidenced by their execution and delivery of this Agreement, hereby consent to the Restructuring and Release as evidenced by this Agreement.

Section 8.1. Maturity. As provided therein, the entire unpaid principal balance of the Notes shall be due and
payable on the stated maturity date thereof. 
 Section 8.2. Optional Prepayments with Make-Whole Amount.
The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding in the case of a
partial prepayment at 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment
under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business day), the aggregate principal amount of the Notes
to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid,
and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the
details of such computation. Two Business days prior to such prepayment, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified
prepayment date. 
 Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment
of the Notes, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for

this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business day), together with interest on such principal amount accrued to such date

principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

 Section 8.5. Purchase of Notes. The Company will not, and
will not permit any Affiliate to, purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the
Notes or (b) pursuant to a written offer to purchase any outstanding Notes made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. If the holders of more than 33% of
the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number
of days necessary to give each such remaining holder at least three (3) Business days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by them or any Affiliate pursuant to any payment,
prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 

Section 8.6. Make-Whole Amount. 

“Make-Whole Amount” means, with respect to any Note of any Series, an amount equal to the excess, if any, of the Discounted
Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the
Make-Whole Amount, the following terms have the following meanings: 
 “Called Principal” means, with respect to any Note
of any Series, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

“Discounted Value” means, with respect to the Called Principal of any Note of any Series, the amount obtained by discounting
all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor
(applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. 

“Reinvestment Yield” means, with respect to the Called Principal of any Note of any Series, 0.50% plus the yield to maturity
calculated by using (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business day preceding the Settlement Date with respect to Called Principal on screen
“PX-1” on the Bloomberg Financial Market Service (or such other display as may replace Page PX1) on Bloomberg for the most recently issued actively traded on the run U.S. Treasury securities
having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of
interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business day preceding the Settlement Date, with respect to such Called Principal, in Federal
Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.


  
 -12- 














			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 In the case of each determination under clause (i) or clause (ii), as the case may
be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating
linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such
Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect
to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due
date of such Remaining Scheduled Payment. 
 “Remaining Scheduled Payments” means, with respect to the Called Principal of
any Note of any Series, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date,
provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest
accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or Section 12.1. 

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be
prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

Section 8.7. Change in Control. 

(a) Notice of Change in Control or Control Event. The Company will, within 15 Business days after any Responsible Officer has knowledge
of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control (or the Change in Control contemplated by
such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (c) of

Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the
name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). If such Proposed Prepayment Date is in connection with an offer contemplated by
subparagraph (a) of this Section 8.7, such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment
Date shall be the 20th day after the date of such offer). 
 (d) Acceptance; Rejection. A holder of Notes may accept or reject
the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance or rejection to be delivered to the Company at least 5 Business days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond
to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder. 
 (e)
Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes, but without the payment of the Make-Whole Amount, together with interest on such Notes accrued to the
date of prepayment. The prepayment shall be made on the Proposed Prepayment Date except as provided in subparagraph (f) of this Section 8.7. 

(f) Deferral Pending Change in Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph
(b) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such Change in
Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change in Control occurs. The Company shall keep each holder of Notes reasonably and timely
informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in
Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change in Control shall be deemed rescinded). 

(g) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate,
executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 8.7; (iii) the principal amount of each
Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.7 have been fulfilled; and (vi) in reasonable
detail, the nature and date or proposed date of the Change in Control.

If any other Event of Default has occurred and is continuing, any holder or holders of more than 51% in principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all
the Notes then outstanding to be immediately due and payable. 
 (c) If any Event of Default described in Section 11(a) or (b) has
occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be
immediately due and payable. 
 Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by
declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate) and (y) the
Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which
are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the
provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such
circumstances. 
 Section 12.2. Other Remedies. If any Default or Event of Default has occurred and is
continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by
an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained in this Agreement or the Notes, or for an injunction against a violation of any of the terms hereof or thereof, or in
aid of the exercise of any power granted hereby or thereby or by law or otherwise. 
 Section 12.3.
Rescission. At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the holders of not less than 51% in principal amount of the Notes then outstanding, by written notice to the Company, may
rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason
of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of

the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of
Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (d) no judgment or
decree has been entered for the payment of any monies due pursuant to this Agreement or the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right
consequent thereon. 
 Section 12.4. No Waivers or Election of Remedies, Expenses, Etc. No course of
dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this
Agreement or the Notes upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the
Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12,
including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

EXCHANGE; SUBSTITUTION OF NOTES. 
 Section 13.1.
Registration of Notes. The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the

information for notices of each transferee of such Note or part thereof), within ten Business days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by
the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the
form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The

of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than $1,000,000 and in an amount which is not an integral of $250,000. Any transferee, by its acceptance of a Note registered in its name (or the name
of its nominee), shall be deemed to have made the representation set forth in Section 7. 
 Section 13.3.
Replacement of Notes. Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft,

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is,
or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $50,000,000 in excess of the outstanding principal amount of such Note or a Qualified Institutional Buyer, such Person’s own unsecured
agreement of indemnity shall be deemed to be satisfactory), or 
 (b) in the case of mutilation, upon surrender and cancellation thereof,
within ten Business days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated
Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon. 

Section 13.4. Legend. Each Note issued on the date of the Closing and each Note issued pursuant to this
Section 13 shall bear a legend substantially as follows (until such time as the Company shall reasonably agree that such legend is no longer necessary or advisable): 

“THIS NOTE HAS NOT BEEN REGISTERED
UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY
OTHER APPLICABLE SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE SOLD OR
OTHERWISE TRANSFERRED UNLESS REGISTERED OR EXEMPT FROM REGISTRATION UNDER SAID ACT

of a bank or trust company in such jurisdiction.

 Section 14.2. Home Office Payment. So long as any Purchaser
or its nominee shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and
interest by the method and at the address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in
writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of
any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to
Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been
paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect

Section 15.1. Transaction Expenses. Whether or not the transactions contemplated hereby are consummated, the
Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required by the Required Holders, local or other counsel) incurred by the Purchasers and each other holder of a Note in
connection with such transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement or the Notes (whether or not such amendment, waiver or consent becomes effective), including, without limitation:
(a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Notes or in responding to any subpoena or other legal process or informal investigative
demand issued in connection with this Agreement or the Notes, or by reason of being a holder of any Note, (b) the costs and expenses, including financial advisors’ fees, incurred in connection with the insolvency or bankruptcy of the
Company or any Subsidiary or in connection with any work-out or restructuring of the transactions contemplated hereby and by the Notes and (c) the costs and expenses incurred in connection with the

 Section 15.2. Survival. The obligations of the Company under this Section 15 will survive the
payment or transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement or the Notes, and the termination of this Agreement or the Notes.

 SECTION 16. SURVIVAL OF REPRESENTATIONS
AND WARRANTIES; ENTIRE AGREEMENT. 
 All representations and warranties
contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any
subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company
pursuant to this Agreement shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement and the Notes embody the entire agreement and understanding between each Purchaser and
the Company and supersede all prior agreements and understandings relating to the subject matter hereof. 
 SECTION 17.
AMENDMENT AND WAIVER. 
 Section 17.1. Requirements. This Agreement and the Notes may be
amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of
any of the provisions of Section 1, 2, 3, 4, 5, 6, 7 or 20 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser in writing, and (b) no such amendment or waiver
may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or
payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on, the Notes, (ii) change the percentage of the principal amount
of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend any of Sections 8, 11(a), 11(b), 12, 17 or 20. 

Section 17.2. Solicitation of Holders of Notes. 

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with
sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions
hereof or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on
which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes. 
 (b) Payment. The
Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration
for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support
concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment. 

  
 -32- 














			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 (c) Consent in Contemplation of Transfer. Any consent made pursuant to this
Section 17 by the holder of any Note that has transferred or has agreed to transfer such Note to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed to provide such written consent as a condition to such
transfer shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and
the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder. 

Section 17.3. Binding Effect, etc. Any amendment or waiver consented to as provided in this Section 17
applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will
extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in
exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be
amended or supplemented. 
 Section 17.4. Notes Held by Company, etc. Solely for the purpose of determining whether the holders of the
requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in
the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be
outstanding. 
 SECTION 18. NOTICES. 

All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on the same day
sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent: 
 (i) if to any Purchaser or its nominee, to such Purchaser or nominee
at the address specified for such communications in Schedule A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing, 

(ii) if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the
Company in writing, or 

  
 -33- 














			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 (iii) if to the Company at its address set forth at the beginning hereof to
the attention of the Vice President and Treasurer, or at such other address as the Company shall have specified to the holder of each Note in writing. 

Notices under this Section 18 will be deemed given only when actually received. 

SECTION 19. REPRODUCTION OF DOCUMENTS. 

This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may
hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be
reproduced by such Purchaser by any photographic, photostatic, electronic, digital, or other similar process and such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by
applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in
the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting
any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. 

SECTION 20. CONFIDENTIAL INFORMATION. 

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of
the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such
Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure,
(b) subsequently becomes publicly known through no act or omission by such Purchaser or any person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any
Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 9.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with
procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors,
officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who
agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note
or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person from which it offers


  
 -34- 














			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 
to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20),
(vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information
about such Purchaser’s investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such
Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may
reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes and this Agreement. Each holder of a Note, by its acceptance of a
Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note
of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the
provisions of this Section 20. 
 SECTION 21. SUBSTITUTION OF PURCHASER. 

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase
hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of
the accuracy with respect to it of the representations set forth in Section 7. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Affiliate in
lieu of such original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company
of notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such
original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement. 
 SECTION 22.
MISCELLANEOUS. 
 Section 22.1. Successors and Assigns. All covenants and other agreements
contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

Section 22.2. Payments Due on Non-Business days. Anything in this
Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business day as the date fixed for such prepayment), any payment of principal of or
Make-Whole Amount or interest on any Note that is due on a date other than a Business day shall be made on the next succeeding Business day without including 

  
 -35- 














			
	CenterPoint Energy Resources Corp.	  	Note Purchase Agreement

  

 
the additional days elapsed in the computation of the interest payable on such next succeeding Business day; provided that if the maturity date of any Note is a date other than a
Business day, the payment otherwise due on such maturity date shall be made on the next succeeding Business day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business day. 

Section 22.3. Accounting Terms. All accounting terms used herein which are not expressly defined in this
Agreement have the meanings respectively given to them in accordance with GAAP; provided that if the Company notifies the holders of Notes that the Company requests an amendment to any provision of this Agreement to eliminate the effect of
any change occurring after the date hereof in GAAP or in the application thereof on the operation of such provision (or if the Required Holders request an amendment to any provision of this Agreement for such purpose), regardless of whether any such
notice is given before or after such change in GAAP or in the application thereof, then such provision shall be interpreted on the basis of GAAP as in effect and applied immediately before such change shall have become effective until such notice
shall have been withdrawn or such provision amended in accordance with this Agreement. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and
(ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with the financial covenants contained in this Agreement, any election by the Company to measure an item of Indebtedness using fair
value (as permitted by Statement of Financial Accounting Standards No. 159 or any similar accounting standard) shall be disregarded and such determination shall be made instead using the par value of such Indebtedness. Notwithstanding any other
provision contained herein, GAAP will be deemed for all purposes hereof to treat leases that would have been classified as operating leases in accordance with GAAP as in effect on December 31, 2014 in a manner consistent with the treatment of
such leases under GAAP as in effect on December 31, 2014, notwithstanding any modifications or interpretive changes thereto or implementations of any such modifications or interpretive changes that may have occurred thereafter. 

Section 22.4. Severability. Any provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the
full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 

Section 22.5. Construction, etc. Each covenant contained herein shall be construed (absent express provision
to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision
herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof.

 Section 22.6. Counterparts. This Agreement may be executed
in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the
parties hereto. 
 Section 22.7. Governing Law. This Agreement shall be construed and enforced in
accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State
that would permit the application of the laws of a jurisdiction other than such State. 
 Section 22.8. Waiver
of Jury Trial. THE PARTIES HERETO HEREBY WAIVE TRIAL BY JURY IN ANY ACTION
BROUGHT ON OR WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY
OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH OR THEREWITH.
