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 $1,050,000,000 3-year unsecured term loan facility (the “Facility”), the proceeds of which would be used by the Borrower for general corporate purposes and for the repayment of debt of the Borrower owing to CenterPoint Energy Resources Corp. (“CERC”).  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 $525,000,000 of the Facility, and (b) UBSLF is pleased to inform the Companies of UBSLF's several, but not joint, commitment to provide $525,000,000 of the Facility, in each case on the terms and subject only to the conditions set forth in Section 1 hereof. 

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 each other financial institution that becomes a party hereto pursuant to a joinder agreement in form and substance reasonably satisfactory to the Initial Commitment Parties and you (a “Joinder Agreement”).  

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 solely 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, which shall be subject to the Certain Funds Provision (as defined below) (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 Closing Date Material Adverse Effect (as defined below); 

(c)    the accuracy in all material respects of the Specified Representations (as defined below) (other than those Specified 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)    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 

(e)    the satisfaction of the other conditions set forth under the heading “Conditions Precedent to Closing” contained in the Term Sheet. 
As used herein, “Closing Date Material Adverse Effect” means a material adverse effect on the business, condition (financial or otherwise), properties, assets, liabilities, obligations (whether absolute, accrued, conditional or otherwise), operations, or results of 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; provided, however, that a Closing Date Material Adverse Effect shall not include any effect on the business, condition (financial or otherwise), properties, assets, liabilities, obligations (whether absolute, accrued, conditional or otherwise), operations or results of operations of the Borrower, its subsidiaries and the assets and businesses to be contributed to the Borrower pursuant to the Transactions to the extent arising out of or attributable to (a) any decrease in the market price of CenterPoint Energy's or OGE Energy Corp.'s publicly traded equity securities (but not any change or effect underlying such decrease to the extent such change or effect would otherwise contribute to a Closing Date Material Adverse Effect), (b) changes in the general state of the industries in which the CNP Midstream Entities and Enogex Entities (each as defined in the Master Formation Agreement referred to in the Transaction Description) operate to the extent that such changes would have the same general effect on companies engaged in such industries, (c) changes in general economic conditions (including changes in commodity prices or interest rates), financial or securities markets or political conditions, in each case to the extent that such changes would have the same general effect on companies engaged in the same lines of business as those conducted by the CNP Midstream Entities and the Enogex Entities, (d) the negotiation, announcement or proposed consummation of the Transactions, including the loss or departure of officers or other 

2

employees of any of the CNP Midstream Entities and the Enogex Entities or any adverse change in customer, distributor, supplier or similar relationships resulting therefrom, (e) changes in United States generally accepted accounting principles or the interpretation thereof or changes in applicable law or the interpretation or enforcement thereof, (f) acts of terrorism, war, sabotage or insurrection not directly damaging or impacting the CNP Midstream Entities and the Enogex Entities, to the extent that such acts have the same general effect on companies engaged in the same lines of business as those conducted by the CNP Midstream Entities and the Enogex Entities, (g) the failure to take any action as a result of any restrictions or prohibitions set forth in Section 6.1 of the Master Formation Agreement (as defined on Exhibit A attached hereto) with respect to which the other parties thereto refused, following the subject party's request, to provide a waiver in a timely manner or at all, (h) compliance with the terms of, or the taking of any action required by, the Master Formation Agreement, (i) the downgrade in rating of any debt or debt securities of CenterPoint Energy, CERC, OGE Energy Corp. (“OGE”) or Enogex, (j) any legal proceedings arising out of or related to the Master Formation Agreement or any of the Transactions or (k) the failure by the CNP Midstream Entities and the Enogex Entities to meet any internal or published industry analyst projections or forecasts or estimates of revenues or earnings for any period (it being understood and agreed that the facts and circumstances that may have given rise or contributed to such failure that are not otherwise excluded from the definition of a Closing Date Material Adverse Effect may be taken into account in determining whether there has been a Closing Date Material Adverse Effect).

Notwithstanding anything in this Commitment Letter, the Fee Letters (as defined below), the Operative Documents or any other letter agreement or other undertaking concerning the financing of the Transactions to the contrary, (i) the only representations and warranties the accuracy of which shall be a condition to availability of the Facility on the Closing Date shall be the Specified Representations (as defined below) in the Operative Documents and (ii) the terms of the Operative Documents shall be in a form such that they do not impair availability of the Facility on the Closing Date if the conditions specified in the immediately preceding paragraph are satisfied.  The only conditions to funding of the Facility on the Closing Date are set forth in the immediately preceding paragraph, and upon satisfaction (or waiver by the Initial Lenders) of such conditions, the initial funding of the Facility shall occur.  For purposes hereof, “Specified Representations” means the representations and warranties of the Borrower set forth in the Operative Documents relating to corporate or other organizational existence; organizational power and authority (as to execution, delivery and performance of the Operative Documents); due authorization, execution and delivery of the Operative Documents; enforceability of the Operative Documents; solvency as of the Closing Date (after giving effect to the Transactions to occur on the Closing Date) of the Borrower and its subsidiaries on a consolidated basis; execution, delivery and performance of the Operative Documents not violating applicable law, charter documents and existing material agreements; OFAC and Patriot Act; Federal Reserve margin regulations; and Investment Company Act.  This paragraph, and the provisions herein, shall be referred to as the “Certain Funds Provision”.

As used herein, “SEC Reports” means, collectively, (i) the Annual Report on Form 10-K of OGE, the Annual Report on Form 10-K of CenterPoint Energy and the Annual Report on Form 10-K of 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 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 the funding of the Facility, 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 4 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 (i) the provisions of Sections 4 and 9 shall not survive if the commitments and undertakings of the Commitment Parties are effectively terminated in full prior to the effectiveness and funding of the Facility and (ii) if the Facility closes and the Operative Documents are executed and delivered, 

3

(A) the provisions of Sections 4 and 9 shall survive only until the date a Successful Syndication is achieved and (B) 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, 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.  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. 

Section 4.  Syndication.  Each Initial Commitment Party reserves the right, before or after the execution of the Operative Documents, to syndicate 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 “Lenders”); provided that, notwithstanding each Initial Commitment Party's right to syndicate the Facility and receive commitments with respect thereto, until the Closing Date, (a) no Initial Commitment Party shall be relieved, released or novated from its obligations hereunder with respect to its original commitment (including such Initial Commitment Party's obligation to fund the Facility on the Closing Date in an amount equal to such original commitment) in connection with any syndication, assignment or participation of the Facility, (b) no assignment or novation shall become effective with respect to all or any portion of any Initial Commitment Party's commitments in respect of the Facility, and (c) unless you collectively otherwise agree in writing, each Initial Commitment Party shall retain exclusive control over all rights and obligations with respect to its commitment in respect of the Facility, including all rights with respect to consents, modifications, supplements, waivers and amendments, in each case, except to the extent any other Lender to which a portion of the Facility has been syndicated has been joined to this Commitment Letter as an additional “Commitment Party” pursuant to a Joinder Agreement.  The commitment of the Initial Commitment Parties shall be ratably reduced dollar-for-dollar by the amount of the commitment of each Lender that has been joined to this Commitment Letter as an additional “Commitment Party” by the execution of a Joinder Agreement.  For the avoidance of doubt, on and after the Closing Date, any Lender may assign its commitments in respect of the Facility in accordance with the assignment provisions set forth in the Operative Documents (which shall be consistent with the “Assignments and Participations” section of the Term Sheet).

Subject to the preceding paragraph, 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. 

Notwithstanding anything to the contrary contained herein (but without limiting your obligations to assist with the Initial Commitment Parties' syndication efforts as set forth herein), it is understood that the Initial Lenders' commitments hereunder are not conditioned upon the syndication of, or receipt of commitments in respect of, the Facility or on the obtaining of ratings for the Facility, and in no event shall the commencement or successful completion of syndication of the Facility or the obtaining of ratings for the Facility constitute a condition to the availability of the Facility on the Closing Date.

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 

4

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).  The obligations of each Company to assist with the syndication of the Facility shall terminate upon the completion of a Successful Syndication (as defined in the Term Loan Arrangers' Fee Letter referred to below) or sixty (60) days after the Closing Date, whichever occurs first. 

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 earliest of (x) 60 days after the Closing Date, (y) completion of a Successful Syndication and (z) 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 $1,400,000,000 five-year revolving credit facility referred to in that certain commitment letter dated as of the date hereof among the Companies and the Initial Commitment Parties (the “Revolving Credit Facility”). 

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 Term Loan Arrangers' Fee Letter dated the date hereof (the “Term Loan Arrangers' Fee Letter”) among the Companies and the Initial Commitment Parties, (b) the Term Loan Administrative Agent Fee Letter dated the date hereof (the “Term Loan Administrative Agent Fee Letter”) among the Companies and Citi, and (c) the Term Loan Administrative Agent Fee Letter dated the date hereof (together with the Term Loan Arrangers' Fee Letter and the Term Loan Administrative Agent Fee Letter, the “Fee Letters”) between CenterPoint Energy 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 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 

6

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, 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 as contemplated by Section 4 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. 

7

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 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 

8

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 Company agrees that no Group is required to restrict its activities as a result of this Commitment Letter and that each Group may undertake any business activity without further consultation with or notification to such Company.  Neither this Commitment Letter nor the receipt by any Commitment Party of confidential information nor any other matter will give rise to any fiduciary, equitable or contractual duties (including without limitation, any duty of trust or confidence) that would prevent or restrict a Group from acting on behalf of other customers or for its own account.  Furthermore, each Company agrees that no Group and no member or business of a Group is under a duty to disclose to it or the Borrower or use on behalf of it or the Borrower any information whatsoever about or derived from those activities or to account for any revenue or profits obtained in connection with such activities.  However, consistent with each Group's long-standing policy to hold in confidence the affairs of its customers, and without limiting each Commitment Party's obligations and rights under Section 8 of this Commitment Letter (and subject to the exceptions set forth in Section 8), no Group will use confidential information obtained from 

9

any Company or the Borrower except in connection with its services to, and its relationship with, such Company and the Borrower.

Section 11.    Governing Law, Etc.  This Commitment Letter will be governed by, and construed in accordance with, the law of the State of New York.  This Commitment Letter and the Fee Letters set forth the entire agreement between the parties with respect to the Facility and supersede all prior communications, written or oral, with respect thereto.  This Commitment Letter may be executed in any number of counterparts, each of which, when so executed, will be deemed to be an original and all of which, taken together, will constitute one and the same Commitment Letter.  Delivery of an executed counterpart of a signature page to this Commitment Letter by facsimile transmission or other electronic transmission (i.e., PDF) will be as effective as delivery of an original executed counterpart of this Commitment Letter.  

Section 12.  Waiver of Jury Trial.  EACH PARTY HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS COMMITMENT LETTER OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES HERETO IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF.

Section 13.  Consent to Jurisdiction, Etc.  Each Company irrevocably and unconditionally (i) submits to the exclusive jurisdiction of any New York State or Federal court located in the City of New York over any suit, action or proceeding arising out of or relating to this Commitment Letter, (ii) accepts for itself and in respect of its property the jurisdiction of such courts, (iii) waives any objection to the laying of venue of any such suit, action or proceeding brought in any such courts and any claim that any such suit, action or proceeding has been brought in an inconvenient forum and (iv) consents to the service of any process, summons, notice or document in any such suit, action or proceeding by registered mail addressed to such Company at its address specified on the first page of this Commitment Letter.  A final judgment in any such suit, action or proceeding will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing herein will affect the right of any Commitment Party to serve legal process in any other manner permitted by law or affect any Commitment Party's right to bring any suit, action or proceeding against any Company or its property in the courts of other jurisdictions.  To the extent that any Company has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, such Company irrevocably waives such immunity in respect of its obligations under this Commitment Letter. 

Section 14.  Patriot Act Compliance.  Each Commitment Party hereby notifies the Companies that pursuant to the requirements of the USA PATRIOT ACT (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Commitment Party to identify the Borrower in accordance with the Patriot Act.  In that connection, each Commitment Party may also request corporate formation documents, or other forms of identification, to verify information provided.

Please indicate your acceptance of the provisions hereof by signing the enclosed copy of this Commitment Letter and the Fee Letters and returning them, to Mary O'Black, Bracewell & Giuliani LLP, 711 Louisiana St., Suite 2300, Houston, Texas 77002 (fax: 713-437-5336, email: mary.o'black@bgllp.com) at or before 5:00 p.m. (New York City time) on March 15, 2013, the time at which the commitments and other obligations of each Commitment Party hereunder (if not so accepted prior thereto) will terminate.

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 Revolving Credit 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 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 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.

B-11

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.

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 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).

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:

(“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 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 “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 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, 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 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 Company agrees that no Group is required to restrict its activities as a result of this Commitment Letter and that each Group may undertake any business activity without further consultation with or notification to such Company.  Neither this Commitment Letter nor the receipt by any Commitment Party of confidential information nor any other matter will give rise to any fiduciary, equitable or contractual duties (including without limitation, any duty of trust or confidence) that would prevent or restrict a Group from acting on behalf of other customers or for its own account.  Furthermore, each Company agrees that no Group and no member or business of a Group is under a duty to disclose to it or the Borrower or use on behalf of it or the Borrower any information whatsoever about or derived from those activities or to account for any revenue or profits obtained in connection with such activities.  However, consistent with each Group's long-standing policy to hold in confidence the affairs of its customers, and without limiting each Commitment Party's obligations and rights under Section 8 of this Commitment Letter (and subject to the exceptions set forth in Section 8), no Group will use confidential information obtained from any Company or the Borrower except in connection with its services to, and its relationship with, such Company and the Borrower.

Section 11.  Governing Law, Etc.  This Commitment Letter will be governed by, and construed in accordance with, the law of the State of New York.  This Commitment Letter and the Fee Letters set forth the entire agreement between the parties with respect to the Facility and supersede all prior communications, written or oral, with respect 

thereto.  This Commitment Letter may be executed in any number of counterparts, each of which, when so executed, will be deemed to be an original and all of which, taken together, will constitute one and the same Commitment Letter.  Delivery of an executed counterpart of a signature page to this Commitment Letter by facsimile transmission or other electronic transmission (i.e., PDF) will be as effective as delivery of an original executed counterpart of this Commitment Letter.  

Section 12.  Waiver of Jury Trial.  EACH PARTY HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS COMMITMENT LETTER OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES HERETO IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

Section 13.  Consent to Jurisdiction, Etc.  Each Company irrevocably and unconditionally (i) submits to the exclusive jurisdiction of any New York State or Federal court located in the City of New York over any suit, action or proceeding arising out of or relating to this Commitment Letter, (ii) accepts for itself and in respect of its property the jurisdiction of such courts, (iii) waives any objection to the laying of venue of any such suit, action or proceeding brought in any such courts and any claim that any such suit, action or proceeding has been brought in an inconvenient forum and (iv) consents to the service of any process, summons, notice or document in any such suit, action or proceeding by registered mail addressed to such Company at its address specified on the first page of this Commitment Letter.  A final judgment in any such suit, action or proceeding will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing herein will affect the right of any Commitment Party to serve legal process in any other manner permitted by law or affect any Commitment Party's right to bring any suit, action or proceeding against any Company or its property in the courts of other jurisdictions.  To the extent that any Company has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, such Company irrevocably waives such immunity in respect of its obligations under this Commitment Letter. 

Section 14.  Patriot Act Compliance.  Each Commitment Party hereby notifies the Companies that pursuant to the requirements of the USA PATRIOT ACT (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Commitment Party to identify the Borrower in accordance with the Patriot Act.  In that connection, each Commitment Party may also request corporate formation documents, or other forms of identification, to verify information provided.

Please indicate your acceptance of the provisions hereof by signing the enclosed copy of this Commitment Letter and the Fee Letters and returning them, to Mary O'Black, Bracewell & Giuliani LLP, 711 Louisiana St., Suite 2300, Houston, Texas 77002 (fax: 713-437-5336, email: mary.o'black@bgllp.com) at or before 5:00 p.m.  (New York City time) on March 15, 2013, the time at which the commitments and other obligations of each Commitment Party hereunder (if not so accepted prior thereto) will terminate.  If you elect to deliver this Commitment Letter by facsimile or other electronic transmission (i.e., PDF), please arrange for the executed original to follow by next-day courier.

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 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, 

B-13

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.
