Ladies and Gentlemen:

     You have advised Credit Suisse AG (acting through such of its affiliates or branches as it deems appropriate, “CS”) and Credit Suisse Securities (USA) LLC (“CS Securities” and, together with CS and their respective affiliates, “Credit Suisse”; Credit Suisse is also herein referred to as “we”, “us”, “our” or the “Commitment Parties”) that you, directly or through one of your wholly owned domestic subsidiaries, intend to acquire (the “Acquisition”) all of the equity interests of Southern Union Company, a Delaware corporation (the “Company”) (such term and each other capitalized term used but not defined herein having the meaning assigned to such term in the Summary of Principal Terms and Conditions attached hereto as Exhibit A (the “Term Sheet”)). This letter amends, restates and supersedes in its entirety that certain commitment letter dated as of July 4, 2011 among you and us.

     You have further advised us that, in connection therewith, the Borrower will obtain the 364-day senior bridge term loan credit facility (the “Bridge Facility”) described in the Term Sheet, in an aggregate principal amount of $3.7 billion (or such lesser amount as you may elect to borrow in your sole discretion).

1. Commitments.

     In connection with the foregoing, CS (in such capacity the “Initial Lender”) is pleased to advise you of its commitment to provide the entire principal amount of the Bridge Facility, upon the terms set forth in this commitment letter (including the Term Sheet and other attachments hereto, this “Commitment Letter”) and the conditions set forth in Section 6 of this Commitment Letter and Exhibit B.

2. Titles and Roles.

     You hereby appoint (a) CS Securities (in such capacity, the “Arranger”) to act, and the Arranger hereby agrees to act, as a sole bookrunner and lead arranger for the Bridge Facility, and (b) CS to act, and CS hereby agrees to act, as sole administrative agent for the Bridge Facility, in each case upon the terms and subject to the conditions set forth or referred to in this Commitment Letter. The Arranger and the Initial Lender, in such capacities, will perform the duties and exercise the authority customarily performed and exercised by it in such roles. You agree that CS will have “left” placement in any and all marketing materials or other documentation used in connection with the Bridge Facility. You further agree that no other titles will be awarded and no compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letters referred to below) will be paid in connection with the Bridge Facility unless you and we shall so agree.

3. Syndication.

     We reserve the right, prior to and/or after the execution of definitive documentation for the Bridge Facility, to syndicate all or a portion of the Initial Lender’s commitment with respect to the Bridge Facility to a group of banks, financial institutions and other institutional lenders (together with the Initial Lender, the “Lenders”) identified by us in consultation with you, and you agree to provide us with a period of at least 30 consecutive days following the launch of the general syndication of the Bridge Facility and prior to the Closing Date to syndicate the Bridge Facility (provided that such period shall not include any day from and including August 21, 2011 through and including September 5, 2011, from and including November 23 through and including November 25, 2011, from and including December 18, 2011 through and including January 2, 2012, from and including June 30, 2012 through and including July 4, 2012 and from and including August 20, 2012 through and including September 4, 2012). Notwithstanding the right to syndicate the Bridge Facility and receive commitments with respect thereto, (i) the Initial Lender shall not be relieved, released or novated from its obligations hereunder (including its obligation to fund the Bridge Facility on the date of the consummation of the Acquisition with the proceeds of the funding under the Bridge Facility) in connection with any syndication or assignment of the Bridge Facility, including its commitments in respect thereof, until after the Closing Date has occurred unless such syndication or assignment is to a Permitted Assignee (as defined) and (ii) no assignment or novation, other than to a Permitted Assignee, shall become effective with respect to all or any portion of the Initial Lender’s commitments in respect of the Bridge Facility until the Closing Date. We intend to commence syndication efforts promptly upon the execution of this Commitment Letter, and you agree to use commercially reasonable efforts to actively assist us in completing a satisfactory syndication. Such assistance shall include (a) your using commercially reasonable efforts to ensure that any syndication efforts benefit materially from your existing lending and investment banking relationships and the existing lending and investment banking relationships of the Company, (b) direct contact between senior management, representatives and advisors of you (and your using commercially reasonable efforts to cause direct contact between senior management, representatives and advisors of the Company) and the proposed Lenders, (c) assistance by you (and your using commercially reasonable efforts to cause the assistance by the Company) in the preparation of a customary Confidential Information Memorandum for the Bridge Facility (the “Information Materials”), (d) prior to the launch of the syndication, confirmation that the Borrower has a Public Debt Rating from each of Standard & Poor’s Ratings Service (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”), and (e) the hosting, with the Arranger, of one meeting of prospective Lenders. Without limiting your obligations to assist with syndication efforts as set forth herein, it is understood that the Initial Lender’s commitments hereunder are not conditioned upon the

syndication of, or receipt of commitments in respect of, the Bridge Facility and in no event shall the commencement or successful completion of syndication of the Bridge Facility constitute a condition to the availability of the Bridge Facility on the Closing Date.

     You agree, at the request of the Arranger, to assist in the preparation of a version of the Information Materials to be used in connection with the syndication of the Bridge Facility, consisting exclusively of information and documentation that is either (i) publicly available (or, if applicable, contained in any prospectus or other offering memorandum related to any securities issues in connection with the Permanent Debt Financing) or (ii) not material with respect to the Borrower, the Company or their respective subsidiaries or any of their respective securities for purposes of United States Federal securities laws (all such Information Materials being “Public Lender Information”). Any information and documentation that is not Public Lender Information is referred to herein as “Private Lender Information”. Before distribution of any Information Materials, you agree to execute and deliver to the Arranger, either (i) a letter in which you authorize distribution of the Information Materials to Lenders’ employees willing to receive Private Lender Information or (ii) a separate letter in which you authorize distribution of Information Materials containing solely Public Lender Information and represent that such Information Materials do not contain any Private Lender Information. You further agree that each document to be disseminated by the Arranger to any Lender in connection with the Bridge Facility will, at the request of the Arranger, be identified by you as either (i) containing Private Lender Information or (ii) containing solely Public Lender Information. You acknowledge that the following documents contain solely Public Lender Information (unless you notify us promptly prior to their intended distribution that any such document contains Private Lender Information): (a) drafts and final definitive documentation with respect to the Bridge Facility, including term sheets; (b) administrative materials prepared by the Commitment Parties for prospective Lenders (such as a lender meeting invitation, bank allocation, if any, and funding and closing memoranda); and (c) notification of changes in the terms of the Bridge Facility.

     The Arranger will manage all aspects of any syndication in consultation with you, including decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted, which institutions will participate, the allocation of the commitments among the Lenders, any naming rights and the amount and distribution of fees among the Lenders.

4. Information.

     You hereby represent and covenant that (with respect to Information and Projections relating to the Company and its subsidiaries, to the best of your knowledge) (a) all written and factual information other than the projections (the “Projections”) and other information of a general economic or industry-specific nature (the “Information”) that have been or will be made available to us by or on behalf of you or any of your representatives is or will be, when furnished, complete and 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 are made after giving effect to all supplements and updates thereto, and (b) the Projections that have been or will be made available to us by or on behalf of you or any of your representatives have been or will be prepared in good faith based upon assumptions that are reasonable at the time made and at the time the related Projections are made available to us (it being understood that the Projections by their nature are inherently uncertain, no assurances are being given that the results reflected in the Projections will be achieved, and actual results may differ materially from the Projections). You agree that if at any time prior to the closing of the

Bridge Facility any of the representations in the preceding sentence would be incorrect if the Information and Projections were being furnished, and such representations were being made, at such time, then you will promptly supplement the Information and the Projections so that such representations will be correct under those circumstances. In arranging and syndicating the Bridge Facility, we will be entitled to use and rely primarily on the Information and the Projections without responsibility for independent verification thereof.

5. Fees.

     As consideration for the Initial Lender’s commitment hereunder, and the Arranger’s agreement to perform the services described herein, you agree to pay to us the fees set forth in this Commitment Letter and in the Amended and Restated Fee Letter (the “Arranger Fee Letter”) and the Amended and Restated Agent Fee Letter (the “Agent Fee Letter” and, together with the Arranger Fee Letter, the “Fee Letters”), each dated the date hereof and delivered herewith with respect to the Bridge Facility.

Form of Solvency Certificate

[See following page]

SOLVENCY CERTIFICATE
OF
ENERGY TRANSFER EQUITY, L.P. AND ITS SUBSIDIARIES

[__], 201__

     This Solvency Certificate (the “Certificate”) of Energy Transfer Equity, L.P., a Delaware limited partnership (the “Borrower”), and its Subsidiaries is delivered pursuant to Section [__] of the 364-Day Credit Agreement dated as of [__] 201__ (the “Credit Agreement”) by and among the Borrower, the Lenders from time to time party thereto, Credit Suisse AG, as Administrative Agent, [__], as Documentation Agent, [__], as Syndication Agent. Unless otherwise defined herein, capitalized terms used in this Certificate shall have the meanings set forth in the Credit Agreement.¹

     I, [ ], the duly elected, qualified and acting Chief Financial Officer of the Borrower, DO HEREBY CERTIFY in my capacity as an officer of the Borrower, as follows:

     1. I have carefully reviewed the Credit Agreement and the other [Loan Documents] referred to therein (collectively, the “Transaction Documents”) and such other documents as I have deemed relevant and the contents of this Certificate and, in connection herewith, have made such investigation, as I have deemed necessary therefor. Furthermore, I confirm and acknowledge that the Administrative Agent and the Lenders are relying on the truth and accuracy of this Certificate in connection with the Commitments and Loans under the Credit Agreement.

     2. I have reviewed the pro forma consolidated balance sheet, attached hereto as Exhibit A, delivered to the Administrative Agent and the Lenders pursuant to Section [__] of the Credit Agreement (the “Balance Sheet”). I am familiar with the financial performance and prospects of the Borrower and its Subsidiaries and hereby confirm that the Balance Sheet was prepared in good faith and fairly presents, on a pro forma basis as of [__] (after giving effect to the transactions contemplated by the Transaction Documents), the Borrower’s and its Subsidiaries’ pro forma consolidated financial condition, based on the information available to the Borrower and its Subsidiaries at the time so furnished.

     3. As of the date hereof, before and after giving effect to the Transactions, the fair value of any and all property of the Borrower and its Subsidiaries, on a consolidated basis, is greater than the probable liability on existing debts of the Borrower and its Subsidiaries, on a consolidated basis, as they become absolute and matured.

     4. As of the date hereof, before and after giving effect to the Transactions, the present fair saleable value of any and all property of the Borrower and its Subsidiaries, on a consolidated basis, is greater than the probable liability on existing debts of the Borrower and its Subsidiaries, on a consolidated basis, as they become absolute and matured.

     As of the date hereof, before and after giving effect to the Transactions, the Borrower and its Subsidiaries, on a consolidated basis, are solvent and are able to pay their debts (including, without limitation, contingent and subordinated liabilities) as they become absolute and mature.

     5. The Borrower and its Subsidiaries, on a consolidated basis, do not intend to, nor do they believe that they will, incur debts that would be beyond their ability to pay as such debts mature.

     6. As of the date hereof, before and after giving effect to Transactions, the Borrower and its Subsidiaries are not engaged in businesses or transactions, nor about to engage in businesses or transactions, for which any property remaining would, on a consolidated basis, constitute unreasonably small capital after giving due consideration to the prevailing practice in the industry in which they are engaged.

[Remainder of page intentionally left blank]

     IN WITNESS WHEREOF, I have executed this Certificate as of the date first written above.
