 COMMITMENT LETTER 
 Ladies and Gentlemen: 

CenterPoint Energy, Inc. (“CenterPoint Energy”) and Enogex LLC (“Enogex” and, together with CenterPoint
Energy, “you” or the “Companies”, and each individually, a “Company”) have advised Citigroup Global Markets Inc. (“CGMI”), UBS Loan Finance LLC (“UBSLF”) and UBS
Securities LLC (“UBS Securities” and, together with CGMI and UBSLF, “we” or “us”) that you plan to form a joint venture (the “Borrower”), which will be a Delaware limited
partnership (and will be the successor to CenterPoint Energy Field Services, LLC, a Delaware limited liability company), and to consummate the other Transactions described in Exhibit A attached hereto (the “Transaction
Description”). In addition, you have informed us that you desire to cause the Borrower to establish a $1,400,000,000 5-year unsecured revolving credit facility (the “Facility”), the proceeds of which would be used by the
Borrower for general corporate purposes and to refinance certain obligations outstanding under Enogex’s existing revolving credit facility. Capitalized terms used in this commitment letter but not defined herein shall have the meanings given to
them in the Transaction Description or the Summary of Terms and Conditions attached hereto as Exhibit B (the “Term Sheet”; this commitment letter, the Transaction Description and the Term Sheet, collectively, the
“Commitment Letter”). 
 In connection with the Transactions, (a) CGMI, on behalf of Citi (as defined
below), is pleased to inform the Companies of Citi’s several, but not joint, commitment to provide $200,000,000 of the Facility, and (b) UBSLF is pleased to inform the Companies of UBSLF’s several, but not joint, commitment to provide
$200,000,000 of the Facility, in each case on the terms and subject to the conditions set forth in Section 1 hereof. 







 In addition, each of Citi and UBS Securities is pleased to inform the Companies of its
agreement to use its best efforts to arrange, in consultation with each of you, a syndicate of Lenders (as defined and subject to the provisions below) for the balance of the Facility, on the terms and subject to the conditions of this Commitment
Letter (it being understood and agreed that none of the Commitment Parties is agreeing to underwrite such syndication). For purposes of this Commitment Letter, (a) “Citi” means CGMI, Citibank, N.A., Citicorp USA, Inc., Citicorp
North America, Inc. and/or any of their affiliates as may be appropriate to consummate the transactions contemplated hereby; (b) “Initial Lenders” means, collectively, Citi and UBSLF; (c) “Initial Commitment
Parties” means, collectively, Citi, UBSLF and UBS Securities; and (d) “Commitment Parties” means, collectively, the Initial Commitment Parties and the Additional Commitment Parties (as defined below). 

The commitment and other obligations of each Commitment Party hereunder are several and not joint. No Commitment Party is responsible for
the performance of the obligations of another Commitment Party, and the failure of a Commitment Party to perform its obligations hereunder will not prejudice the rights of any other Commitment Party hereunder. 

Section 1. Conditions Precedent. Each Commitment Party’s commitment hereunder and agreement to perform the
services described herein are subject to the following conditions: 
 (a) the preparation, execution and delivery
of mutually acceptable definitive loan documentation for the Facility, including, without limitation, a credit agreement incorporating substantially the terms and conditions outlined in this Commitment Letter (the “Operative
Documents”); 
 (b) other than as disclosed in the SEC Reports (as defined below) or otherwise prior to
the date hereof, the absence since December 31, 2012 of any material adverse change in the business, condition (financial or otherwise) or operations of the Borrower, its subsidiaries and the assets and businesses to be contributed to the
Borrower pursuant to the Transactions, taken as a whole; 
 (c) the accuracy in all material respects of the
representations of the Companies contained herein (other than those representations that are subject to a materiality qualifier in the text thereof, which shall be accurate in all respects) and the performance in all material respects by the
Companies of their agreements hereunder; 
 (d) the receipt of commitments from Lenders (other than Citi and
UBSLF) of not less than $600,000,000, on the terms and conditions set forth in Annex I; 
 (e) such Commitment
Party not discovering or otherwise becoming aware of any information not previously disclosed to it that is inconsistent in a material and adverse manner with the information provided to it prior to the date hereof, regarding the business, condition
(financial or otherwise), or operations of the Borrower, its subsidiaries and the assets and businesses to be contributed to the Borrower pursuant to the Transactions, taken as a whole; and 

(f) the satisfaction of the other conditions set forth under the heading “Conditions Precedent to Closing”
contained in the Term Sheet. 
 As used herein, “SEC Reports” means, collectively, (i) the Annual Report
on Form 10-K of OGE Energy Corp. (“OGE”), the Annual Report on Form 10-K of CenterPoint Energy and the Annual Report on Form 10-K of CenterPoint Energy Resources Corp. (“CERC”), in each case, for the fiscal year
ended December 31, 2012, and (ii) the Current Reports on Form 8-K filed by OGE, the Current Reports on Form 

  
 2 








 
8-K filed by CenterPoint Energy and the Current Reports on Form 8-K filed by CERC, in each case, after the Annual Report on Form 10-K for the fiscal year ended December 31, 2012 for such
company and prior to the date hereof. 
 Section 2. Commitment Termination; Survival of Obligations. Each
Commitment Party’s commitment and other obligations set forth in this Commitment Letter will terminate on the earlier of (a) the occurrence of the Closing Date, and (b) December 31, 2013, provided, that if on December 31,
2013 the only condition under the Master Formation Agreement (as defined on Exhibit A) not satisfied or waived is the condition set forth in Section 7.1(a) of the Master Formation Agreement, then the commitments and other obligations of the
Commitment Parties set forth in this Commitment Letter will terminate on February 28, 2014. In addition, the Companies, acting together, may terminate the commitments set forth in this Commitment Letter at any time in whole or in part upon
written notice to the Commitment Parties. Notwithstanding the foregoing, the provisions of Sections 5 through 8 and 10 through 13 shall remain in full force and effect regardless of whether any Operative Documents shall be executed and delivered and
notwithstanding the termination of this Commitment Letter or any commitment or undertaking of the Commitment Parties hereunder, provided that if the Facility closes and the Operative Documents are executed and delivered, the provisions under
Sections 6 and 7 and the second paragraph of Section 8 shall be superseded and deemed replaced by the terms of the Operative Documents governing such matters (solely to the extent such provisions are set forth therein). 

Section 3. Titles and Roles. Citi will act as the sole administrative agent for the Facility, UBS Securities will act
as syndication agent for the Facility, and CGMI and UBS Securities will act as joint lead arrangers and joint bookrunners for the Facility. It is understood and agreed that Citi will have “left” placement in all marketing materials and
other documentation used in connection with the Facility. Except as provided in the immediately succeeding paragraph, no additional agents, co-agents or arrangers will be appointed, no other titles will be awarded and no compensation (except as set
forth in this Commitment Letter and the Fee Letters) will be paid to any Lender in order to obtain its commitment to participate in the Facility, without the consent of the Initial Commitment Parties. 

Notwithstanding the foregoing, after the date hereof, you may arrange for one or more additional financial institutions (each, an
“Additional Commitment Party”) selected by you and reasonably acceptable to us (it being acknowledged and agreed that each of Wells Fargo Bank, National Association and JPMorgan Chase Bank, N.A. shall be acceptable to both us and
you) to provide (pursuant to customary joinder documentation reasonably satisfactory to you and us) additional commitments to the Facility, and add each Additional Commitment Party as a party to this Commitment Letter as an additional joint lead
arranger and joint bookrunner for the Facility and award such agent or co-agent titles to such Additional Commitment Party as you, we and the joint lead arrangers may agree; provided that (a) no Additional Commitment Party shall receive
economics greater than the economics received by each of the Initial Commitment Parties and (b) the fees set forth in the Fee Letters payable to Citi and UBS Securities may not be reduced as a result of the addition of a new Additional
Commitment Party. Each party hereto agrees to execute such joinders, amendments and other documents as are required to give effect to this paragraph. From and after the execution by any financial institution of such joinder documentation, such
financial institution (and any relevant affiliate) shall constitute a “Commitment Party” hereunder, and it or its relevant affiliate providing such commitment shall constitute an “Initial Lender” hereunder. 

Section 4. Syndication. Each Initial Commitment Party intends to syndicate, prior to the Closing Date, all or a
portion of the Facility (including all or part of such Initial Commitment Party’s commitment) to one or more other financial institutions listed on the list distributed by us to you on the date hereof (the “Approved Lenders”)
and any other financial institutions subject to your reasonable mutual consent, which financial institutions will become parties to the Operative Documents pursuant to a syndication to be managed by the Initial Commitment Parties in consultation
with you (such financial institutions becoming parties to the Operative Documents, including the Initial Lenders, being collectively referred to herein as the 

  
 3 








 
“Lenders”); provided that none of the commitments of the Initial Lenders may be syndicated or participated until the earlier of the (i) the Closing Date and
(ii) such time as at least $1,400,000,000 has been committed to the Facility by Lenders (including the Initial Lenders). Subject to the preceding sentence, the Initial Commitment Parties will manage all aspects of the syndication in
consultation with each of you, including the timing of all offers to potential Lenders, the determination of the amounts offered to potential Lenders, the acceptance of commitments of the Lenders, the assignment of any titles and the compensation to
be provided to the Lenders. 
 Each Company will take all actions as any Initial Commitment Party may reasonably request to
assist the Initial Commitment Parties in forming a syndicate for the Facility reasonably acceptable to the Initial Commitment Parties and to the Companies, which acceptance by the Companies will be deemed to be given for any Approved Lender. Each
Company’s assistance in forming such a syndicate will include, without limitation, (a) making senior management and representatives of such Company and the Borrower available to participate in information meetings with potential Lenders
and rating agencies at such times and places as any Initial Commitment Party may reasonably request; (b) using such Company’s commercially reasonable efforts to ensure that the syndication efforts benefit from such Company’s existing
lending relationships; (c) assisting (including using its commercially reasonable efforts to cause its affiliates and advisors to assist) in the preparation of a confidential information memorandum for the Facility and other marketing and
rating agency materials to be used in connection with the syndication of the Facility; and (d) subject to Section 9, promptly providing the Initial Commitment Parties with all other information reasonably deemed necessary by any of them to
successfully complete the syndication of the Facility (it being understood, however, that the only financial statements that shall be required to be provided to the Initial Commitment Parties in connection with the syndication of the Facility shall
be those required to be delivered pursuant to the Term Sheet). 
 Each Company acknowledges that (a) the Initial Commitment
Parties may make available any Information and Projections (each as defined in Section 9) (collectively, the “Borrower Materials”) to potential Lenders on a confidential basis by posting the Borrower Materials on DebtDomain or
another similar electronic system (the “Platform”) and (b) certain of the potential Lenders may be “public side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the
Borrower or its securities) (each, a “Public Lender”). Each Company agrees that (i) at the request of the Initial Commitment Parties, it will assist us in preparing a version of the information package and presentation to be
provided to potential Lenders that does not contain material non-public information concerning the Companies, the Borrower or any securities of any thereof for purposes of United States federal and state securities laws; (ii) all Borrower
Materials that are to be made available to Public Lenders will be clearly and conspicuously marked “PUBLIC” which, at a minimum, will mean that the word “PUBLIC” will appear prominently on the first page thereof; (iii) by
marking Borrower Materials “PUBLIC,” each Company will be deemed to have authorized the Initial Commitment Parties and the proposed Lenders to, among other things, treat such Borrower Materials as not containing any material non-public
information (although they may be confidential or proprietary) with respect to the Borrower or its securities for purposes of United States federal and state securities laws; (iv) all Borrower Materials marked “PUBLIC” are permitted
to be made available through a portion of the Platform designated “Public Lender,” and (v) the Initial Commitment Parties will be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only
for posting on a portion of the Platform not designated “Public Lender.” Each of the Initial Commitment Parties hereby agrees that it shall obtain from each Lender or prospective Lender to which it disseminates any non-public or
confidential information regarding the Companies, their respective affiliates or the Borrower, an agreement (which agreement may be deemed to be made by the acceptance by such Lender or prospective Lender of the Confidential Information Memorandum)
to treat such information as confidential pursuant to the terms of the Special Notice and the Notice and Undertaking set forth in the Confidential Information Memorandum prepared for the Facility.

 To ensure an effective syndication of the Facility, each Company agrees that, until the
earlier of (x) the Closing Date and (y) termination of this Commitment Letter prior to the Closing Date, the Borrower will not, and will not permit any of its subsidiaries to, syndicate or issue, attempt to syndicate or issue, announce or
authorize the announcement of the syndication or issuance of, or engage in discussions concerning the syndication or issuance of, any debt facility or debt security of the Borrower or any of its subsidiaries in the syndicated bank loan market
(including any renewals thereof) without the prior written consent of the Initial Commitment Parties, other than the $1,050,000,000 three-year term loan facility referred to in that certain commitment letter dated as of the date hereof among the
Companies and the Initial Commitment Parties. 
 Section 5. Fees. In addition to the fees described in the
Term Sheet, each Company will pay (or cause to be paid) the non-refundable fees set forth in (a) the Revolver Arrangers’ Fee Letter dated the date hereof (the “Revolver Arrangers’ Fee Letter”) among the Companies and
the Initial Commitment Parties and (b) the Revolver Administrative Agent Fee Letter dated the date hereof (together with the Revolver Arrangers’ Fee Letter, the “Fee Letters”) among the Companies and Citi, in each case if
and to the extent payable by such Company thereunder. 
 Section 6. Indemnification. You, severally and not
jointly, agree to indemnify and hold harmless (in each case, in accordance with your Percentage (as defined below)), each of the Commitment Parties and their respective affiliates and each of their respective officers, directors, employees,
advisors, agents and representatives (each, an “Indemnified Party”) from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and disbursements of counsel, which
shall be limited to a single firm of counsel for all Indemnified Parties, taken as a whole, and, if reasonably necessary, a single firm of local or regulatory counsel in each appropriate jurisdiction and a single firm of special counsel for each
relevant specialty, in each case for all Indemnified Parties, taken as a whole and, solely in the case of an actual or perceived conflict of interest (as reasonably identified by an Indemnified Party) where the Indemnified Party affected by such
conflict informs you of such conflict, one additional firm of counsel in each relevant jurisdiction for the affected Indemnified Parties similarly situated, taken as a whole) that may be incurred by or asserted or awarded against any Indemnified
Party (including without limitation, in connection with any investigation, litigation or proceeding or the preparation of a defense in connection therewith), in each case, arising out of or in connection with or by reason of this Commitment Letter,
the Fee Letters or the Operative Documents or the transactions contemplated hereby or thereby or any actual or proposed use of the proceeds of the Facility, except to the extent such claim, damage, loss, liability or expense is found in a final,
non-appealable judgment by a court of competent jurisdiction to have resulted from (i) the gross negligence, bad faith or willful misconduct of such Indemnified Party, (ii) a material breach by such Indemnified Party of its obligations
under this Commitment Letter or the Fee Letters, or (iii) claims of one or more Indemnified Parties against another Indemnified Party (other than claims against the Agent or the joint lead arrangers in their capacities as such) and not
involving any act or omission of the Companies, the Borrower or any subsidiaries or affiliates of any of the foregoing (or any of such person’s officers, directors, employees, advisors, agents or representatives). In the case of an
investigation, litigation or other proceeding to which the indemnity in this paragraph applies, such indemnity will be effective whether or not such investigation, litigation or proceeding is brought by any Company, the Borrower, any of their
respective directors, security holders or creditors, an Indemnified Party or any other person or an Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. 

No Indemnified Party will have any liability (whether direct or indirect, in contract, tort or otherwise) to any Company, the Borrower or
any of their affiliates or any of their respective security holders or creditors for or in connection with the transactions contemplated hereby, except to the extent such liability is determined in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from (i) the gross negligence, bad faith or willful misconduct of such Indemnified Party, (ii) a material breach by such Indemnified Party of its obligations under this Commitment Letter or the Fee


  
 5 








 
Letters, or (iii) claims of one or more Indemnified Parties against another Indemnified Party (other than claims against the Agent or the joint lead arrangers in their capacities as such)
and not involving any act or omission of the Companies, the Borrower or any subsidiaries or affiliates of any of the foregoing (or any of such person’s officers, directors, employees, advisors, agents or representatives). No party hereto nor
any of its affiliates nor any of their respective officers, directors, employees, advisors, agents, representatives or controlling persons shall be liable to any other party hereto (or its affiliates, officers, directors, employees, advisors,
agents, representatives or controlling persons) on any theory of liability for any special, indirect, consequential or punitive damages (including without limitation, any loss of profits, business or anticipated savings) in connection with this
Commitment Letter, the Fee Letters or the Facility; provided that nothing contained in this sentence shall limit your indemnification obligations set forth in the immediately preceding paragraph, including your obligation to indemnify
Indemnified Parties for special, indirect, consequential or punitive damages awarded against an Indemnified Party. 
 Each
Company acknowledges that information and other materials relative to the Facility and the transactions contemplated hereby may be transmitted through the Platform. No Indemnified Party will be liable to any Company, the Borrower or any of their
affiliates or any of their respective security holders or creditors for any damages arising from the use by unauthorized persons of information or other materials sent through the Platform that are intercepted by such persons, except to the extent
such damages are incurred by reason of the willful misconduct or gross negligence of an Indemnified Party, in each case, as determined by a final, non-appealable judgment of a court of competent jurisdiction. 

Section 7. Costs and Expenses. Each Company, severally and not jointly, agrees to pay (or cause to be paid), or
reimburse the Commitment Parties (in each case, in accordance with such Company’s Percentage (as defined below)) for, all reasonable out-of-pocket costs and expenses (including the reasonable fees and expenses of Bracewell & Giuliani
LLP, counsel to Citi in its capacity as administrative agent and an arranger for the Facility, and no other counsel of any other Lender or Commitment Party) incurred by any of them (whether incurred before or after the date hereof) in connection
with the Facility and the preparation, negotiation, execution and delivery of this Commitment Letter, the Fee Letters and the Operative Documents, regardless of whether any of the transactions contemplated hereby are consummated. Such amounts shall
be paid on the earlier of (i) the Closing Date and (ii) five business days following the termination of this Commitment Letter as provided below. Each Company also, severally and not jointly, agrees to pay (or cause to be paid) (in
accordance with such Company’s Percentage) all costs and expenses of the Commitment Parties (including, without limitation, the reasonable fees and disbursements of counsel, which shall be limited to a single firm of counsel for all Commitment
Parties, taken as a whole, and, if reasonably necessary, a single firm of local or regulatory counsel in each appropriate jurisdiction and a single firm of special counsel for each relevant specialty, in each case for all Commitment Parties, taken
as a whole and, solely in the case of an actual or perceived conflict of interest (as reasonably identified by an Indemnified Party), where the Commitment Party affected by such conflict informs you of such conflict, one additional firm of counsel
in each relevant jurisdiction for the affected Commitment Parties similarly situated, taken as a whole) incurred in connection with the enforcement of any of their respective rights and remedies under this Commitment Letter or the Fee Letters.

 As used herein, “Percentage” shall mean, with respect to CenterPoint Energy, 50% and, with respect to
Enogex, 50%. 
 Section 8. Confidentiality. By accepting delivery of the Fee Letters and this Commitment
Letter, each Company agrees that each of the Fee Letters and, prior to your acceptance hereof, this Commitment Letter are for your confidential use only and that neither the existence nor the terms of the Fee Letters and this Commitment Letter will
be disclosed by you to any person other than the Borrower and your and the Borrower’s respective affiliates and your and their respective officers, directors, employees, accountants, attorneys, other advisors, agents and representatives (the
“Company Representatives”), and then only on a confidential and “need to know” basis in connection with the transactions contemplated hereby; provided, 

  
 6 








 
that (i) you may file a copy of this Commitment Letter (but not any Fee Letter) in any public record in which this Commitment Letter is required by law to be filed, (ii) you may
disclose this Commitment Letter and the contents thereof and the aggregate fee amounts contained in the Fee Letters to rating agencies in connection with obtaining ratings for the Borrower and the Facility, provided that such rating agencies are
informed of the confidential nature of such information and of their obligation to keep such information confidential, (iii) you may make a generic disclosure of aggregate sources and uses including the aggregate amount of fees related to the
Transactions to the extent customary or required in marketing materials for the Facility or in any public release or filing related to the Transactions, (iv) you may make public disclosures of the terms and conditions hereof to the extent such
terms and conditions have become publicly available as a result of disclosures thereof by persons other than, to the extent prohibited hereby, you, your affiliates or any of your or their respective officers, directors, employees, advisors, agents
or representatives, (v) you may make such public disclosures of the terms and conditions hereof and of the Fee Letters as you are required by law or regulation to make or as may be requested or required by regulatory authorities having
jurisdiction over you (in which case you shall (x) promptly notify the Initial Commitment Parties in advance of disclosure, to the extent permitted by law and to the extent practicable, and (y) so furnish only that portion of such
information which you are legally required to disclose), (vi) you may make such public disclosures of the terms and conditions hereof and of the Fee Letters if you are legally compelled to do so in connection with any litigation or similar
proceeding (in which case you shall (x) promptly notify the Initial Commitment Parties in advance of disclosure, to the extent permitted by law and to the extent practicable, and (y) so furnish only that portion of such information which
you are legally required to disclose), (vii) you may disclose this Commitment Letter and the Fee Letters (to the extent the fees contained in such Fee Letter are in dispute or in issue) and the contents thereof to a court, tribunal or any other
applicable judicial authority in connection with the enforcement of your rights hereunder (in which case, you shall promptly notify the Initial Commitment Parties in advance of such disclosure to the extent permitted by law), (viii) you may
make such public disclosures of the terms and conditions hereof and of the Fee Letters where the Initial Commitment Parties jointly consent to the proposed disclosure and (ix) you may disclose this Commitment Letter and the contents hereof to
prospective Additional Commitment Parties who are reasonably acceptable to us in accordance with Section 3 hereof. Notwithstanding any other provision in this Commitment Letter, the Commitment Parties hereby confirm that the Companies and the
Company Representatives will not be limited from disclosing the U.S. tax treatment or U.S. tax structure of the Facility. 

Each of the Commitment Parties agrees to maintain the confidentiality of all Specified Information (as defined below); provided
that nothing herein shall prevent any Commitment Party from disclosing any Specified Information (a) to any other Commitment Party, (b) to prospective Lenders who have been approved by you in accordance with the terms hereof, (c) to
any of its affiliates solely in connection with the transactions contemplated hereby, (d) to its employees, directors, agents, attorneys, accountants and other professional advisors or those of any of its affiliates who are informed of the
confidential nature of such information and of their obligation to keep such information confidential, (e) upon the request or demand of any governmental authority or any regulatory authority having jurisdiction over such Commitment Party,
(f) in response to any order of any court or other governmental authority having jurisdiction over such Commitment Party or as may otherwise be required pursuant to any requirement of law or as requested by any self-regulatory body (in which
case such Commitment Party shall (i) promptly notify you in advance of disclosure, to the extent permitted by law and to the extent practicable, and (ii) so furnish only that portion of such information which it is legally required to
disclose), (g) if legally compelled to do so in connection with any litigation or similar proceeding (in which case such Commitment Party shall (i) promptly notify you in advance of disclosure, to the extent permitted by law and to the
extent practicable, and (ii) so furnish only that portion of such information which it is legally required to disclose), (h) to the extent any such information becomes publicly available other than by reason of disclosure by any Commitment
Party, its affiliates or any of their respective employees, directors, agents, attorneys, accountants or other professional advisors in breach of this Commitment Letter, (i) in connection with protecting its rights with respect to this
Commitment Letter and the exercise of any remedy under this Commitment Letter or any loan document 

  
 7 








 
related to any of the Facilities or (j) with your joint written consent. The Commitment Parties shall be responsible for any breach of the provisions of this paragraph by any of their
affiliates and any of their or their affiliates’ employees and directors. “Specified Information” means all information that is made available to any Commitment Party by or on behalf of by the Companies, the Borrower or any
Company Representatives in connection with the transactions contemplated hereby, other than any such Information that is available to such Commitment Party on a non-confidential basis prior to disclosure by any Company or any of their respective
representatives, excluding any information from a source which, to such Commitment Party’s knowledge, has been disclosed by such source in breach of the terms hereof. 
 Section 9. Representations and Warranties of the Companies. Each Company represents and warrants that (a) (i) all written information, other than Projections (as defined below),
that has been or will hereafter be made available to any Commitment Party, any Lender or any potential Lender by such Company, the Borrower or any Company Representative of such Company or the Borrower in connection with the transactions
contemplated hereby and (ii) all information orally communicated by such Company, the Borrower or any Company Representative of such Company or the Borrower to any Initial Commitment Party or any of their attorneys in due diligence sessions or
to any Commitment Party, any Lender or any potential Lender in formal lender presentations (the “Information”), when taken as a whole after giving effect to all supplements and updates provided thereto, is or will be, when
furnished, correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially
misleading in light of the circumstances under which such statements were or are made and (b) all financial projections and forward looking statements, if any, that have been or will be prepared by such Company, the Borrower or any Company
Representative of such Company or the Borrower and made available to any Commitment Party, any Lender or any potential Lender (the “Projections”) have been or will be prepared in good faith based upon assumptions that are or were,
in good faith, believed by such Company’s or the Borrower’s management to be reasonable as of the date of the preparation of such Projections (it being understood that the Projections are subject to significant uncertainties and
contingencies, many of which are beyond the Companies’ and the Borrower’s control, and that no assurance can be given (and no representation shall be deemed made) that the Projections will be realized). If, at any time from the date hereof
until the termination of this Commitment Letter, any of the representations and warranties in the preceding sentence would not be accurate and complete in any material respect if the Information or Projections were being furnished, and such
representations and warranties were being made, at such time, then each Company agrees to promptly supplement the Information and/or Projections from time to time so that the representations and warranties contained in this paragraph remain accurate
and complete in all material respects under those circumstances; it being agreed that (i) such information shall be deemed to have been provided by the Companies as required hereunder by any Company’s delivery of written notice to the
Initial Commitment Parties that such information has been included or disclosed in any periodic or current report filed by such Company (or any of its related filing affiliates) with the Securities and Exchange Commission and (ii) the Companies
shall have no obligation to update or supplement the Projections included in that certain “Midstream JV Ratings Agency Presentation” dated January 31, 2013. You also agree to promptly advise us of all developments materially and
adversely affecting the Borrower or the assets and businesses that are to be contributed to the Borrower pursuant to the Transactions, taken as a whole; it being agreed that such information shall be deemed to have been provided by the Companies as
required hereunder by any Company’s delivery of written notice to the Initial Commitment Parties that such information has been included or disclosed in any periodic or current report filed by such Company (or any of its related filing
affiliates) with the Securities and Exchange Commission. 
 In providing this Commitment Letter and in arranging the Facility,
the Initial Commitment Parties are relying on the accuracy of the Information furnished to them by or on behalf of the Companies, the Borrower or any Company Representatives without independent verification thereof.

 Section 10. No Third Party Reliance, Not a Fiduciary, Etc. The agreements
of the Commitment Parties hereunder and of any Lender that issues a commitment to provide financing under the Facility are made solely for the benefit of you and the Commitment Parties, as applicable, and may not be relied upon or enforced by any
other person. Please note that those matters that are not covered or made clear herein are subject to mutual agreement of the parties. You may not assign or delegate any of your rights or obligations hereunder without the Initial Commitment
Parties’ prior written consent. This Commitment Letter may not be amended or modified, or any provision hereof waived, except by a written agreement signed by all parties hereto. 

Each Company hereby acknowledges that each of the Commitment Parties is acting pursuant to a contractual relationship on an arm’s
length basis, and the parties hereto do not intend that the Commitment Parties act or be responsible as a fiduciary to it, the Borrower, their management, stockholders, creditors or any other person. Each Company and each Commitment
Party hereby expressly disclaims any fiduciary relationship and agrees they are each responsible for making their own independent judgments with respect to any transactions entered into between them. Each Company also hereby acknowledges that the
Commitment Parties have not advised and are not advising it as to any legal, accounting, regulatory or tax matters, and that it and the Borrower are consulting their own advisors concerning such matters to the extent it deems appropriate. You
also acknowledge that UBS Securities is acting as financial advisor to OGE in connection with various matters, including the Transactions, and that Citi is acting as financial advisor to CenterPoint Energy in connection with various matters,
including the Transactions. 
 Each Company understands that each Commitment Party and its affiliates (each Commitment Party,
together with its affiliates, being collectively, a “Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and
research). Members of each Group and businesses within each Group generally act independently of each other, both for their own account and for the account of clients. Accordingly, there may be situations where parts of a Group and/or their clients
either now have or may in the future have interests, or take actions, that may conflict with a Company’s interests. For example, a Group may, in the ordinary course of business, engage in trading in financial products or undertake other
investment businesses for their own account or on behalf of other clients, including without limitation, trading in or holding long, short or derivative positions in securities, loans or other financial products of a Company or its affiliates or
other entities connected with the Facility or the transactions contemplated hereby. 
 In recognition of the foregoing, each

unanimous Lender consent and the consent of the Majority Lenders has been obtained.
  
 In addition, the Borrower shall have the right at any time that no event of default exists, in its sole discretion, to remove a Lender upon 15 business days’ written notice to such Lender being

 Ratings in the above Ratings-Based Pricing Grid are based on the Designated Ratings issued by
Standard & Poor’s Financial Services LLC (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings (“Fitch” and, together with S&P and Moody's, the
“Rating Agencies” and each, a “Rating Agency”). “Designated Rating” means, with respect to any Rating Agency, (i) the rating assigned by such Rating Agency to the Facility at any time such a
rating is in effect, (ii) if and only if such Rating Agency does not have in effect a rating described in the preceding clause (i), the rating assigned by such Rating Agency to the Term Loan Facility, (iii) if and only if such Rating
Agency does not have in effect a rating described in the preceding clauses (i) or (ii), the Borrower’s long-term senior unsecured non-credit enhanced debt rating, or (iv) if and only if such Rating Agency does not have in effect a
rating described in the preceding clauses (i), (ii) or (iii), the Borrower’s “company” or “corporate credit” rating (or its equivalent) assigned by such Rating Agency. 

For purposes of the foregoing, (i) if the Designated Ratings are split and all three ratings fall in different levels, the pricing
shall be based upon the level indicated by the middle rating; (ii) if the 

  
 B-19









 
Designated Ratings are split and two of the ratings fall in the same level (the “Majority Level”) and the third rating is in a different level, the pricing shall be based upon
the Majority Level; (iii) if only two of the three rating agencies issue a Designated Rating, the higher of such ratings shall apply, provided that if the higher rating is two or more levels above the lower rating, the rating next below the
higher of the two shall apply; (iv) if only one of the three rating agencies issues a Designated Rating, such rating shall apply; and (v) if the Designated Rating established by S&P, Moody’s or Fitch shall be changed (other than
as a result of a change in the rating system of S&P, Moody’s or Fitch), such change shall be effective as of the date on which it is first announced by the applicable rating agency. If the rating system of S&P, Moody’s or Fitch
shall change, or if any of S&P, Moody’s or Fitch shall cease to be in the business of rating corporate debt obligations, the Borrower and the Agent shall negotiate in good faith if necessary to amend this provision to reflect such changed
rating system or the unavailability of Designated Ratings from such rating agencies and, pending the effectiveness of any such amendment, the applicable commitment fee rate, the Applicable Margin for Eurodollar Rate Advances and the Applicable
Margin for Base Rate Advances shall be determined by reference to the Designated Rating of such rating agency most recently in effect prior to such change or cessation. 
 C. Base Rate Definition 
 “Base Rate” means for any period,
a fluctuating interest rate per annum as shall be in effect from time to time, which rate per annum shall be equal at all times to the highest of the following: (a) the rate of interest announced publicly by Citibank, N.A. at its principal
office in New York, New York, from time to time, as its prime rate; (b) 0.5% per annum plus the federal funds rate and (c) the Eurodollar Rate for a one-month interest period that begins on such day (and if such day is not a business
day, the immediately preceding business day) plus 1%. 
 D. Eurodollar Rate Definition  

“Eurodollar Rate” means, with respect to any interest period for any Eurodollar Rate Advance, the rate appearing on the
Reuters Reference LIBOR01 page (or on any successor or substitute page of such service, or any successor to or substitute for such service, providing rate quotations comparable to those currently provided on such page of such service, as determined
by the Agent from time to time for purposes of providing quotations of interest rates applicable to deposits in Dollars in the London interbank market) at approximately 11:00 a.m., London time, on the second business day next preceding the first day
of such interest period, as the rate for deposits in Dollars with a maturity comparable to such interest period. In the event that such rate is not available at such time for any reason, then the “Eurodollar Rate” for such interest period
shall be the rate at which dollar deposits of $5,000,000 and for a maturity comparable to such interest period are offered by the principal London office of the Agent in immediately available funds in the London interbank market at approximately
11:00 a.m., London time, on the second business day next preceding the first day of such interest period.
