     WHEREAS, each of the Board of Directors of the Company and Merger Sub have (a) determined that it is in the best interests of the Company and Merger Sub, respectively, and their respective stockholders, and declared it advisable, to enter into this Agreement, (b) approved the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the Merger and (c) resolved to recommend adoption of this Agreement by their respective stockholders;

     NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained herein, and intending to be legally bound hereby, Parent, Merger Sub and the Company agree as follows, and the First Amended Merger Agreement is hereby amended and restated in its entirety with effect from the date of execution of the Original Agreement, as follows:

ARTICLE I.

THE MERGER

     Section 1.1. The Merger. At the Effective Time, upon the terms and subject to the conditions set forth in this Agreement and in accordance with the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”), Merger Sub shall be merged with and into the Company, whereupon the separate corporate existence of Merger Sub shall cease, and the Company shall continue its corporate existence under Delaware law as the surviving corporation in the Merger (the “Surviving Corporation”) and a direct wholly owned subsidiary of Parent.

     Section 1.2. Closing. The closing of the Merger (the “Closing”) shall take place at the offices of Locke Lord Bissell & Liddell, 600 Travis Street, Suite 2800, Houston, Texas at 10:00 a.m., local time, on a date to be agreed upon by the parties in writing (the “Closing Date”), which shall be no later than the third business day after the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their nature are to be satisfied by action taken at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other place, date and time as the Company and Parent may agree in writing; provided, however, that upon satisfaction or waiver of all the conditions set forth in Article VI (excluding conditions that, by their terms, cannot be satisfied until the Closing Date, but subject to the satisfaction or waiver of such conditions) Parent may, on one occasion, by giving written notice to the Company no later than two business days prior to the date the Closing is scheduled to occur, elect to postpone the Closing Date for a period of time not to exceed 15 consecutive business days in order to facilitate the Financings.

     Section 1.3. Effective Time. On the Closing Date, the Company and Merger Sub shall file the certificate of merger (the “Certificate of Merger”), executed in accordance with, and containing such information as is required by, the relevant provisions of the DGCL with the Secretary of State of the State of Delaware. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such later time as is agreed between the parties and specified in the Certificate of Merger in accordance with the relevant provisions of the DGCL (such date and time is hereinafter referred to as the “Effective Time”).

     Section 1.4. Effects of the Merger. The effects of the Merger shall be as provided in this Agreement and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation, all as provided under the DGCL.

     Section 1.5. Certificate of Incorporation and By-laws of the Surviving Corporation.

     (a) At the Effective Time, the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and applicable Law.

     (b) At the Effective Time, the by-laws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the by-laws of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and hereof and applicable Law.

     Section 1.6. Directors. Subject to applicable Law, the directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

     Section 1.7. Officers. The officers of Merger Sub immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

     Section 1.8. Merger Sub Contribution. Immediately prior to the Effective Time, the Company shall contribute to Merger Sub the funds, if any, it receives pursuant to the Citrus Transfer (not to exceed $1,450,000,000) in exchange for an equity interest in Merger Sub proportionate to its Deemed Share. Such obligation shall be deemed satisfied by the Company’s compliance with clause (ii) of Section 2.3(a). As used herein, “Deemed Share” means the fraction (a) the numerator of which is the amount, if any, contributed by the Company to Merger Sub pursuant to this Section 1.8 and (b) the denominator of which is the aggregate value of the Merger Consideration, valuing the Common Units based upon the volume weighted average price of the Common Units for the five trading days ending on the trading day immediately preceding the Effective Time.

ARTICLE II.

CONVERSION OF SHARES; EXCHANGE OF CERTIFICATES

     Section 2.1. Effect on Capital Stock.

     (a) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Merger Sub or the holders of any securities of the Company or Merger Sub, each share of common stock, par value $1.00 per share of the Company (such shares, collectively, “Company Common Stock”, and each, a “Share”) issued and outstanding immediately prior to the Effective Time (other than Cancelled Shares and Dissenting Shares) (the “Acquired Shares”) shall, by virtue of this Agreement and without any action on the part of the holder thereof, be converted into and shall thereafter represent the right to receive the following consideration (collectively, the “Merger Consideration”), calculated in the following order:

	(i)		Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time with respect to which an election to receive cash (a “Cash Election”) has been effectively made and not revoked or lost pursuant to Section 2.2 (each, a “Cash Election Share”) shall be converted into the right to receive $44.25 in cash without interest (the “Per Share Cash Consideration”); provided, however, if (A) the product of the Per Share Cash Consideration and the number of Cash Election Shares (such product being the “Cash Election Amount”) exceeds the Available Cash Election Amount, then each Cash Election Share shall be converted into a right to receive (1) an amount of cash (without interest) equal to the product of (p) the Per Share Cash Consideration and (q) a fraction, the numerator of which shall be the Available Cash Election Amount and the denominator of which shall be the Cash Election Amount (such fraction being the “Cash Fraction”) and (2) a number of Common Units equal to the product of (r) 1.00 (the “Exchange Ratio”) and (s) one (1) minus the Cash Fraction. The “Available Cash Election Amount” shall equal (A) the product of (x) 0.60, (y) the Per Share Cash Consideration and (z) the total number of shares of Company Common Stock (other than the Cancelled Shares) issued and outstanding immediately prior to the Effective Time minus (B) the product of the Per Share Cash Consideration and the total number of Dissenting Shares immediately prior to the Effective Time.
	(ii)		Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time with respect to which an election to receive consideration consisting of Common Units (a “Common Unit Election”) is properly made and not revoked or lost pursuant to Section 2.2 (each, a “Common Unit Election Share”), and each No Election Share (which shall be deemed to be Common Unit Election Shares for purposes of this Section 2.1(a)(ii)), shall be converted into the right to receive that number of Common Units equal to the Exchange Ratio (together with any

			cash in lieu of fractional Common Units to be paid pursuant to Section 2.1(d), the “Per Share Common Unit Consideration”); provided, however, if the Cash Election Amount is less than an amount equal to 5/6 (five sixths) multiplied by the Available Cash Election Amount (the amount of such shortfall, if any, the “Shortfall Amount”), then each Common Unit Election Share shall be converted into the right to receive (1) a number of Common Units equal to the product of (x) the Exchange Ratio and (y) a fraction, the numerator of which shall be the Per Share Cash Consideration minus the amount of cash calculated in clause (2) below and the denominator of which shall be the Per Share Cash Consideration and (2) an amount of cash (without interest) equal to the amount the Shortfall Amount divided by the number of Common Unit Election Shares.
	(iii)		Of the Shares converted pursuant to this Section 2.1(a), a number of shares equal to the Deemed Share of the Acquired Shares shall be treated as having been acquired by the Company pursuant to a transaction described in Section 317(b) of the Code.

     (b) Cancellation of Shares. Each Share that is held directly or indirectly by the Company or any of its wholly owned Subsidiaries immediately prior to the Effective Time (in each case, other than any Shares held on behalf of third parties) (the “Cancelled Shares”) shall, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange for such cancellation and retirement.

     (c) Conversion of Merger Sub Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of common stock, par value $1.00 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully-paid and nonassessable share of common stock, par value $1.00 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation. From and after the Effective Time, all certificates representing the capital stock of Merger Sub shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

     (d) Fractional Units. No fractional Common Units shall be issued in the Merger, but in lieu thereof each holder of Shares otherwise entitled to a fractional Common Unit will be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 2.1(d), a cash payment in lieu of such fractional Common Unit representing such holder’s proportionate interest, if any, in the proceeds from the sale by the Exchange Agent (reduced by any fees of the Exchange Agent attributable to such sale) in one or more transactions of Common Units equal to the excess of (A) the aggregate number of Common Units to be delivered to the Exchange Agent by Parent pursuant to Section 2.3(a) over (B) the aggregate number of whole Common Units to be distributed to the holders of Shares pursuant to Section 2.3(b) (such excess, the “Excess Shares”). No certificates or scrip representing fractional Common Units shall be issued in the Merger. The parties acknowledge

that payment of the cash consideration in lieu of issuing fractional Common Units was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance of fractional Common Units. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Shares in lieu of any fractional Common Units, the Exchange Agent shall make available such amounts to such holders of Shares, without interest, subject to and in accordance with Section 2.2.

     (e) Adjustments to the Exchange Ratio. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of the Company or Parent shall occur as a result of any reclassification, stock or unit split (including a reverse stock or unit split) or combination, exchange or readjustment of shares or units, or any stock or unit dividend or stock or unit distribution with a record date during such period, the Exchange Ratio, the Per Share Common Unit Consideration, the Per Share Cash Consideration, the Merger Consideration and any other similarly dependent items shall be equitably adjusted to provide to Parent, Merger Sub and the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action, and thereafter, all references in this Agreement to the “Exchange Ratio,” “Per Share Common Unit Consideration,” “Per Share Cash Consideration,” “Merger Consideration” and any other similarly dependent items shall be references to the Exchange Ratio, Per Share Common Unit Consideration, Per Share Cash Consideration, Merger Consideration and any other similarly dependent items as so adjusted; provided, however, that nothing in this Section 2.1(e) shall be deemed to permit or authorize any party hereto to effect any such change that it is not otherwise authorized or permitted to undertake pursuant to this Agreement.

     (f) Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Shares that are issued and outstanding immediately prior to the Effective Time and which are held by stockholders properly exercising appraisal rights available under Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into or be exchangeable for the right to receive the Merger Consideration, unless and until such holders shall have failed to perfect or shall have effectively withdrawn or lost their rights to appraisal under the DGCL. Holders of Dissenting Shares shall be entitled to payment of the appraised value of the Dissenting Shares held by them to the extent permitted by and in accordance with Section 262 of the DGCL. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right to appraisal, such holder’s Shares shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal shall have been irrevocably lost, withdrawn or expired, the Merger Consideration specified in Section 2.1(a)(iii); provided, in such circumstance, to the fullest extent permitted by Law, that Parent shall be entitled at its sole option to convert each such share into the right to receive the Merger Consideration specified in either Section 2.1(a)(i) or 2.1(a)(ii). The Company shall give Parent and Merger Sub (i) prompt written notice of any demands for appraisal of any Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights to be paid the “fair value” of Dissenting Shares, as provided in Section 262 of the DGCL, and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent which will not be unreasonably withheld or delayed, voluntarily make or agree to make any material payment with

respect to any demands for appraisals of capital stock of the Company, offer to settle or settle any such demands.

     Section 2.2. Election Procedures.

     (a) An election form and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing shares of Company Common Stock shall pass, only upon proper delivery of such Certificates to the Exchange Agent) in such form as Parent shall specify and as shall be reasonably acceptable to the Company (the “Election Form”) shall be mailed thirty days prior to the anticipated Closing Date or on such other date as Parent and the Company shall mutually agree (the “Mailing Date”) to each holder of record of Company Common Stock as of the close of business on the fifth business day prior to the Mailing Date (the “Election Form Record Date”).

     (b) Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions), other than any holder of Dissenting Shares, to specify (i) the number of shares of such holder’s Company Common Stock with respect to which such holder elects to receive the Per Share Common Unit Consideration and (ii) the number of shares of such holder’s Company Common Stock with respect to which such holder elects to receive the Per Share Cash Consideration. Any Shares with respect to which the Exchange Agent has not received an effective, properly completed Election Form on or before 5:00 p.m., New York time, on the twentieth (20th) day following the Mailing Date (or such other time and date as Parent and the Company shall agree) (the “Election Deadline”) (other than Cancelled Shares or any shares of Company Common Stock that constitute Dissenting Shares as of such time) shall be deemed to be “No Election Shares”.

     (c) Parent shall make available one or more Election Forms as may reasonably be requested from time to time by all Persons who become holders (or beneficial owners) of Company Common Stock between the Election Form Record Date and the close of business on the business day prior to the Election Deadline, and the Company shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein.

     (d) Any such election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by one or more certificates (or customary affidavits and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such certificate) representing all shares of Company Common Stock covered by such Election Form, together with duly executed transmittal materials included in the Election Form. Any Election Form may be revoked or changed by the Person submitting such Election Form, by written notice received by the Exchange Agent prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the shares of Company Common Stock represented by such Election Form shall become No Election Shares and Parent shall cause the certificates representing such shares of Parent Common Stock to be promptly returned without charge to the Person submitting the Election Form upon written request to that effect from the holder who submitted the Election Form, except to the extent (if

any) a subsequent election is properly made with respect to any or all of such shares of Company Common Stock. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent, the Company or the Exchange Agent shall be under any obligation to notify any Person of any defect in an Election Form.

     Section 2.3. Exchange of Shares.

     (a) Exchange Agent. Prior to the Effective Time, Parent shall appoint an exchange agent mutually acceptable to Parent and the Company (the “Exchange Agent”) for the purpose of exchanging Shares for Merger Consideration. Prior to the Effective Time, (i) Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, in trust for the benefit of holders of the Shares (other than the Cancelled Shares and any Dissenting Shares), certificates representing the Common Units issuable pursuant to Section 2.1(a) and Section 5.6(a) (or appropriate alternative arrangements shall be made by Parent if uncertificated Common Units will be issued) and an amount of cash sufficient (when combined with the Company Cash Funds) to effect the delivery of the Merger Consideration to the holders of Company Common Shares (other than Cancelled Shares and any Dissenting Shares) and (ii) the Company shall deposit the Company Cash Funds with the Exchange Agent. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 2.3(c). All such certificates representing Common Units and cash deposited with the Exchange Agent from time to time is hereinafter referred to as the “Exchange Fund.” As used herein, “Company Cash Funds” means the cash proceeds received, if any, by the Company pursuant to the Citrus Transfer, not to exceed $1,450,000,000.

     (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time and in any event not later than the fifth business day following the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of Shares, which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 2.1, (i) a letter of transmittal (which shall specify that delivery shall be effected, and that risk of loss and title to the Shares shall pass, only upon delivery of the Shares to the Exchange Agent) and (ii) instructions for use in effecting the surrender of the Shares in exchange for, as applicable, cash Merger Consideration, certificates representing whole Common Units (or appropriate alternative arrangements shall be made by Parent if uncertificated Common Units will be issued), cash in lieu of any fractional Common Units pursuant to Section 2.1(d) and any distributions payable pursuant to Section 2.3(c). Upon surrender of Shares for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Shares shall be entitled to receive in exchange therefor, as applicable, that number of whole Common Units (after taking into account all Shares surrendered by such holder) to which such holder is entitled pursuant to Section 2.1 and payment by cash or check of that amount of cash Merger Consideration to which such holder is entitled pursuant to Section 2.1, that amount of cash in lieu of fractional Common Units which such holder is entitled to receive pursuant to Section 2.1(d) and any distributions payable pursuant to Section 2.3(c), and the Shares so surrendered shall forthwith be cancelled. If any cash

payment is to be made to, or any Common Units constituting any part of the Merger Consideration is to be registered in the name of, a person other than the person in whose name the applicable surrendered Share is registered, it shall be a condition to the payment or registration thereof that the surrendered Share be in proper form for transfer and that the person requesting such payment or delivery of the Merger Consideration pay any transfer or other similar Taxes required as a result of such registration in the name of a person other than the registered holder of such Share or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 2.2(b), each Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 2.1(d) or Section 2.3(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 2.1(d) or Section 2.3(c).

     (c) Distributions with Respect to Unexchanged Shares.

Pt. 34) as are customarily granted to entities with market-based rate authority. Each such Subsidiary has obtained an order from the FERC finding it, or has in good faith self-certified itself to the FERC, to be an Exempt Wholesale Generator under PUHCA.

Each of Parent and its Subsidiaries is qualified to do business, and is in good standing as a foreign entity in each jurisdiction where the ownership, leasing or operation of its assets or properties or conduct of its business requires such qualification, except where the failure to be so organized, validly existing, qualified or in good standing, or to have such power or authority, would not have, individually or in the aggregate, a Parent Material Adverse Effect.

     (b) As used in this Agreement, a “Parent Material Adverse Effect” means a material adverse event, change, effect, development, condition or occurrence on or with respect to the business, financial condition or continuing results of operations of Parent and its Subsidiaries, taken as a whole, other than any event, change, effect, development, condition or occurrence: (i) disclosed in the Parent SEC Documents filed or furnished prior to the date of this Agreement (excluding any disclosure set forth in any risk factor section, or in any Section relating to forward looking statements, and any other disclosures therein, in each case, to the extent that they are cautionary and predictive or forward looking in nature) or as disclosed on the face of the Parent Disclosure Schedule (ii) in or generally affecting the economy or the financial or securities markets in the United States or elsewhere in the world, or (iii) resulting from or arising out of (A) any changes or developments in national, regional, state or local wholesale or retail markets for natural gas, natural gas transmission or distribution or related products or services including those due to actions by competitors or due to changes in commodities prices or hedging markets therefor, (B) any changes or developments in national, regional, state or local wholesale or retail natural gas prices (C) the announcement or the existence of, or compliance with, this Agreement or the Original Merger Agreement or the transactions contemplated hereby or thereby (including the impact thereof on the relationships, contractual or otherwise, of Parent or any of its Subsidiaries with employees, labor unions, customers, suppliers or partners, and including any lawsuit, action or other proceeding with respect to the Merger or any of the other transactions contemplated by this Agreement or the Original Merger Agreement), (D) any taking of any action at the written request of the Company, (E) any adoption, implementation, promulgation, repeal, modification, reinterpretation or proposal of any rule, regulation, ordinance, order, protocol or any other Law of or by any national, regional, state or local Governmental Entity, or market administrator, (F) any changes in GAAP or accounting standards or interpretations thereof, (G) any weather-related or other force majeure event or outbreak or escalation of hostilities or acts of war or terrorism, or (H) any changes in the share price or trading volume of the Common Units or in Parent’s credit rating, or the failure of Parent to meet projections or forecasts (unless due to any event, change, effect, development, condition or occurrence which has otherwise resulted in a Parent Material Adverse Effect); except, in each case with respect to subclauses (A) – (B) and (E) – (G) of this clause (iii), to the extent materially disproportionately affecting Parent and its Subsidiaries, taken as a whole, relative to other similarly situated companies in the industries in which Parent and its Subsidiaries operate

The execution and delivery of this Agreement and the other Parent Transaction Documents and the consummation of the transactions contemplated hereby and thereby have been duly and validly authorized by the general partner of Parent and the Board of Directors of Merger Sub, and no other entity or equity-holder proceedings on the part of Parent, Merger Sub or their respective equity holders, except Parent as the sole stockholder of Merger Sub, are necessary to authorize the consummation of the transactions contemplated hereby. As of the Second Amendment Date, the general partner of Parent has unanimously approved the issuance of Common Units (the “Unit Issuance”) in connection with the Merger. Each of the Parent Transaction Documents has been duly and validly executed and delivered by Parent and Merger Sub and, assuming such Parent Transaction Document constitutes the legal, valid and binding agreement of the counterparty thereto, each of the Parent Transaction Documents constitutes the legal, valid and binding agreement of each of Parent and Merger Sub and is enforceable against Parent and Merger Sub in accordance with its terms, except as such enforcement may be limited by the Remedies Exceptions.

     (b) Other than in connection with or in compliance with (i) the Exchange Act, (ii) the Securities Act, (iii) the rules and regulations of the NYSE, (iv) the HSR Act, (v) the FPA and the FERC Approval, (vi) the MDPU Approval, (vii) the MPSC Approval, (viii) the FCC Approval, and (ix) the approvals set forth in Section 4.3(b) of the Parent Disclosure Schedule (collectively, the “Parent Approvals”), and, subject to the accuracy of the representations and warranties of the Company in Section 3.3(b), no authorization, consent, order, license, permit or approval of, or registration, declaration, notice or filing with, any Governmental Entity is necessary, under applicable Law, for the consummation by Parent or Merger Sub of the transactions contemplated by this Agreement, except for the filing of the Certificate of Merger and for such authorizations, consents, approvals or filings that are not required to be obtained or made prior to consummation of such transactions or that, if not obtained or made, would not materially impede or delay the consummation of the Merger and the other transactions contemplated by this Agreement or materially and adversely affect the ability of Parent and its Subsidiaries to operate their business in the ordinary course consistent with past practices.

     (c) The execution and delivery by Parent and Merger Sub of this Agreement do not, and, assuming receipt of the Parent Approvals, the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not (i) result in any loss, or material suspension, limitation or impairment of any right of Parent or any of its Subsidiaries to own or use any assets material to the conduct of their business or result in any material violation

of, or material default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any material obligation or to the loss of a material benefit under any loan, guarantee of indebtedness or credit agreement, note, bond, mortgage, indenture, lease, agreement, contract, instrument, permit, concession, franchise, right or license binding upon Parent or any of its Subsidiaries or result in the creation of any Liens other than Permitted Liens, in each case, upon any of the properties or assets of Parent or any of its Subsidiaries, (ii) conflict with or result in any violation of any provision of the certificate of incorporation or by-laws or other equivalent organizational document, in each case as amended or restated, of Parent or any of its Subsidiaries or (iii) materially conflict with or materially violate any applicable Laws.

     Section 4.4. Reports and Financial Statements.

     (a) Parent and each of its Subsidiaries has filed or furnished all forms, documents and reports required to be filed or furnished prior to the date hereof by it with the SEC since January 1, 2009 (the “Parent SEC Documents”). As of their respective dates or, if amended, as of the date of the last such amendment, the Parent SEC Documents complied in all material respects with the requirements of the Securities Act and the Exchange Act, as the case may be, and the applicable rules and regulations promulgated thereunder, and none of the Parent SEC Documents contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except that information set forth in the Parent SEC Documents as of a later date (but before the date of this Agreement) will be deemed to modify information as of an earlier date.

     (b) The consolidated financial statements (including all related notes and schedules) of Parent included in the Parent SEC Documents fairly present in all material respects the consolidated financial position of Parent and its consolidated Subsidiaries, as at the respective dates thereof, and the consolidated results of their operations and their consolidated cash flows for the respective periods then ended (subject, in the case of the unaudited statements, to normal year-end audit adjustments and to any other adjustments described therein, including the notes thereto) in conformity with GAAP (except, in the case of the unaudited statements, as permitted by the SEC) applied on a consistent basis during the periods involved (except as may be indicated therein or in the notes thereto).

     Section 4.5. Internal Controls and Procedures. Parent has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act. Parent’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act. Parent’s management has completed an assessment of the effectiveness of Parent’s internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley

Act for the year ended December 31, 2010, and such assessment concluded that such controls were effective. Based on its most recent evaluation of internal control over financial reporting prior to the date hereof, management of Parent has disclosed to Parent’s auditors and the audit committee of the board of directors of the general partner of Parent (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting that are reasonably likely to adversely affect in any material respect Parent’s ability to report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal control over financial reporting, and each such deficiency, weakness and fraud so disclosed to auditors, if any, has been disclosed to the Company prior to the date hereof.

     Section 4.6. No Undisclosed Liabilities. Except (a) as reflected or reserved against in Parent’s consolidated balance sheets (or the notes thereto) included in the Parent SEC Documents, (b) as permitted or contemplated by this Agreement, (c) for liabilities and obligations incurred since December 31, 2010 in the ordinary course of business consistent with past practice and (d) for liabilities or obligations which have been discharged or paid in full in the ordinary course of business, neither Parent nor any Subsidiary of Parent has any liabilities or obligations of any nature, whether or not accrued, contingent or otherwise, that would be required by GAAP to be reflected on a consolidated balance sheet of Parent and its consolidated Subsidiaries (or in the notes thereto), other than those which would not have, individually or in the aggregate, a Parent Material Adverse Effect.

     Section 4.7. Compliance with Law; Permits.

     (a) Parent and each of its Subsidiaries are in compliance with and are not in default under or in violation of any applicable Law, except where such non-compliance, default or violation would not have, individually or in the aggregate, a Parent Material Adverse Effect.

     (b) Parent and its Subsidiaries are in possession of all franchises, grants, authorizations, licenses, permits, easements, variances, exceptions, consents, certificates, approvals, clearances, permissions, qualifications and registrations and orders of all Governmental Entities, and all rights under any Parent Material Contract with all Governmental Entities, and have filed all tariffs, reports, notices and other documents with all Governmental Entities necessary for Parent and its Subsidiaries to own, lease and operate their properties and assets or to carry on their businesses as they are now being conducted (the “Parent Permits”), except where the failure to have any of the Parent Permits would not have, individually or in the aggregate, a Parent Material Adverse Effect. All Parent Permits are valid and in full force and effect and are not subject to any administrative or judicial proceeding that could result in modification, termination or revocation thereof, except where the failure to be in full force and effect would not have, individually or in the aggregate, a Parent Material Adverse Effect. Parent is, and each of its Subsidiaries is, in compliance in all respects with the terms and requirements

of such Parent Permits, except where the failure to be in compliance would not have, individually or in the aggregate, a Parent Material Adverse Effect.

     Section 4.12. Information Supplied. None of the information provided by Parent or its Subsidiaries for inclusion or incorporation by reference in (a) the Form S-4 will, at the time the Form S-4 becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading or (b) the Proxy Statement will, at the date it is first mailed to the Company’s stockholders or at the time of the Stockholders’ Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

     Section 4.22. Financing. As of the Second Amendment Date, Parent has delivered to the Company true, complete and correct copies of the fully executed commitment letter (such letter, as amended, modified or waived from time to time to the extent permitted herein, or any financing commitment in respect of an Alternative Financing as contemplated by the last sentence of Section 5.18(b), the “Commitment Letter”) and fee letter (the “Fee Letter”) executed in connection with the debt financing of a portion of the cash component of the Merger

Consideration (the “Financing”) (with certain fee amounts and certain economic terms of the “market flex” provisions redacted). As of the Second Amendment Date, the Commitment Letter is in full force and effect and constitutes the legal, valid, binding and enforceable obligations of Parent and, to the knowledge of Parent, the other parties thereto (subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws affecting creditors’ rights generally and general principles of equity). As of the Second Amendment Date, the Commitment Letter has not been amended or modified in any respect and the respective commitments therein have not been withdrawn or terminated.

As of the Second Amendment Date, assuming satisfaction of the conditions set forth in Section 6.3, Parent has no reason to believe that either it or any other party will be unable to satisfy on a timely basis any condition of the Financing under the Commitment Letter or the Fee Letter or that the Financing contemplated by the Commitment Letter will not be made available to Parent on the Closing Date; provided that Parent is not making any representation or warranty regarding the Company’s future performance, the effect of any inaccuracy of the representations and warranties of the Company in this Agreement or the failure of the Company to comply with any of its covenants in all material respects under this Agreement.

     Section 4.23. No Additional Representations. Parent and Merger Sub acknowledge that the Company does not make any representation or warranty as to any matter whatsoever except as expressly set forth in this Agreement or in any certificate delivered by the Company to Parent or Merger Sub in accordance with the terms hereof, and specifically (but without limiting the generality of the foregoing) that the Company makes no representation or warranty with respect to (a) any projections, estimates or budgets delivered or made available to Parent or Merger Sub (or any of their respective affiliates, officers, directors, employees or Representatives) of future revenues, results of operations (or any component thereof), cash flows or financial condition (or any component thereof) of the Company and its Subsidiaries or (b) the future business and operations of the Company and its Subsidiaries, and neither Parent or Merger Sub has relied on such information or any other representations or warranties not set forth in this Agreement.

	(xxi)		except in the ordinary course of business in accordance with past practice, take or fail to take any action, or permit any of its Subsidiaries to take or fail to take any action, that could cause the Company or any of its Subsidiaries, or any of their assets or businesses that is not already so regulated or treated to be a natural gas company as defined in the NGA, a public utility, transmitting utility, electric utility or electric utility

			company under the FPA, a non-exempt holding company under PUHCA, a common carrier under the ICA or a utility, utility holding company, intrastate pipeline, gas service company, electric service company, gas company, electric company, or any similar entity however described under the laws of any state or local jurisdiction and the regulations promulgated thereunder; and

	(i)		except in the ordinary course of business, shall not authorize or make any distribution with respect to its outstanding equity securities (whether in cash, assets, partnership units, stock or other securities of Parent or its Subsidiaries), except (A) regular quarterly cash distributions with customary record and payment dates on the Common Units not in excess of $0.625 per Common Unit per quarter, and (B) regular quarterly cash distributions with customary record and payment dates on the Series A Preferred Units not in excess of $2.00 per Series A Preferred Unit per quarter plus any accrued and unpaid distributions on the Series A Preferred Units from prior quarters;

     (c) For the avoidance of doubt, none of the restrictions contained in this Section 5.2 shall apply to ETP or its Subsidiaries.

     Section 5.3. Mutual Access.

     (a) For purposes of furthering the transactions contemplated hereby, each of the Company and Parent shall afford the other party and (i) the officers and employees and (ii) the accountants, consultants, legal counsel, financial advisors and agents and other representatives

(such persons described in this clause (ii), collectively, “Representatives”) of such other party reasonable access during normal business hours, throughout the period prior to the earlier of the Effective Time and the Termination Date, to its and its Subsidiaries’ personnel and properties, contracts, commitments, books and records and any report, schedule or other document filed or received by it pursuant to the requirements of applicable Laws and with such additional accounting, financing, operating, environmental and other data and information regarding the Company and its Subsidiaries, as Parent may reasonably request, and Parent and its Subsidiaries, as the Company may reasonably request, as the case may be. Notwithstanding the foregoing, neither the Company nor Parent shall be required to afford such access if it would unreasonably disrupt the operations of such party or any of its Subsidiaries, would cause a violation of any agreement to which such party or any of its Subsidiaries is a party, would cause a risk of a loss of privilege to such party or any of its Subsidiaries or would constitute a violation of any applicable Law. The foregoing notwithstanding, neither the Company nor Parent, nor any of their respective officers, employees or Representatives, shall be permitted to perform any onsite procedures (including an onsite study) with respect to any property of the other party or any of the other party’s Subsidiaries without the other party’s prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned).

     (b) The parties hereto hereby agree that all information provided to them or their respective officers, directors, employees or Representatives in connection with this Agreement and the consummation of the transactions contemplated hereby shall be deemed to be “Evaluation Material,” as such term is used in, and shall be treated in accordance with, the confidentiality agreement, dated as of May 12, 2011, among the Company, ETP and Parent (the “Confidentiality Agreement”).

     Section 5.4. Non-Solicitation by the Company.

     (a) The Company agrees that neither it nor any Subsidiary of the Company, nor any of their respective officers, directors or employees, shall, and that it shall use its reasonable best efforts to cause its and their respective Representatives not to (and shall not authorize or give permission to its and their respective Representatives to), directly or indirectly: (i) solicit, initiate, seek or knowingly encourage or facilitate the making, submission or announcement of, any proposal that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal, (ii) furnish any non-public information regarding the Company or any of its Subsidiaries to, or afford access to the business, properties, books or records of the Company or any of its Subsidiaries to, any person (other than Parent or Merger Sub), in connection with or in response to an Acquisition Proposal, (iii) engage or participate in any discussions or negotiations with any person (other than Parent or Merger Sub) with respect to any Acquisition Proposal, (iv) approve, endorse or recommend (or publicly propose to approve, endorse or recommend) any Acquisition Proposal, (v) enter into any letter of intent, term sheet, memorandum of understanding, merger agreement, acquisition agreement, exchange agreement or any other agreement providing for any Acquisition Transaction or requiring the Company to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement (except as contemplated by Section 7.1(h)) or (vi) resolve, propose or agree to do any of the foregoing; provided, however, that this Section 5.4 shall not prohibit (A) the Company, or the Board of Directors of the Company, directly or indirectly through any officer, employee or Representative, prior to obtaining the Company Stockholder Approval, from taking any of the

actions described in clauses (ii) or (iii) above in response to an unsolicited Acquisition Proposal that the Board of Directors of the Company, prior to taking any such particular action, concludes in good faith, after consultation with its financial advisors and outside legal counsel (it being understood that, for purposes of this Section 5.4, such a financial advisor or outside legal counsel shall include a financial advisor or outside legal counsel to a duly constituted and acting committee of the Board of Directors of the Company), constitutes or is reasonably likely to result in a Superior Offer if (1) the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel, that the failure to take such action with respect to such Acquisition Proposal would be reasonably likely to constitute a breach by the Board of Directors of its fiduciary duties under applicable Laws, (2) such Acquisition Proposal did not result from a breach of this Section 5.4, (3) the Company gives to Parent the notice required by Section 5.4, and (4) the Company furnishes any non-public information provided to the maker of the Acquisition Proposal only pursuant to a confidentiality agreement between the Company and such person on substantially the same terms as the Confidentiality Agreement (it being acknowledged and agreed that such confidentiality agreement need not contain a “standstill” or similar provision that prohibits the third party recipient of such information from making any Acquisition Proposal) and to the extent non-public information that has not been made available to Parent is made available to the maker of the Acquisition Proposal, provide such non-public information to Parent substantially concurrent with the time that it is provided to such other person; (B) the Company from complying with Rules 14d-9 and 14e-2 promulgated under the Exchange Act with regard to any Acquisition Proposal (or making any similar communication to stockholders in connection with any amendment to the terms of a tender offer or exchange offer) so long as any action taken or statement made to so comply is consistent with this Section 5.4; (C) the Company, or the Board of Directors, directly or indirectly through any officer, employee or Representative disclosing factual information regarding the business, financial condition or results of operations of the Company or the fact that an Acquisition Proposal has been made, the identity of the party making such proposal or the material terms of such proposal in the Proxy Statement or otherwise, to the extent the Company in good faith determines that such information, facts, identity or terms is required to be disclosed under applicable Law or that failure to make such disclosure is reasonably likely to be inconsistent with its fiduciary duties under applicable Law; or (D) the Company, or the Board of Directors, directly or indirectly through any officer, employee or Representative making any statement or disclosure to the Company’s stockholders required by applicable Law; provided that any such action taken or statement or disclosure made that relates to an Acquisition Proposal shall be deemed to be a Change of Recommendation unless the Board of Directors reaffirms its recommendation in favor of the proposed transaction in such statement or disclosure or in connection with such action (except that a mere “stop, look and listen” disclosure in compliance with Rule 14d-9(f) of the 1934 Act shall not constitute a Change of Recommendation). So long as the Company and its Representatives have otherwise complied with this Section 5.4, none of the foregoing shall prohibit the Company and its Representatives from contacting in writing any persons or group of persons who has made an Acquisition Proposal after the date of this Agreement solely to request the clarification of the terms and conditions thereof so as to determine whether the Acquisition Proposal is, or could reasonably be expected to lead to, a Superior Offer, and any such actions shall not be a breach of this Section 5.4.

     (b) The Company shall promptly, and in no event later than twenty-four (24) hours after its or any of its Representatives’ receipt of any Acquisition Proposal or any request for non-

public information relating to the Company or any of its Subsidiaries in connection with an Acquisition Proposal, advise Parent orally and in writing of such Acquisition Proposal or request (including providing the identity of the person making or submitting such Acquisition Proposal or request, and, (x) if it is in writing, a copy of such Acquisition Proposal and any related draft agreements and (y) if oral, a reasonably detailed summary thereof that is made or submitted by any person during the period between the date hereof and the Closing). The Company shall keep Parent informed in all material respects on a prompt basis with respect to any change to the material terms of any such Acquisition Proposal (and in no event later than twenty-four (24) hours following any such change). The Company agrees that it shall promptly provide to Parent any non-public information concerning itself or its Subsidiaries provided to any other person in connection with any Acquisition Proposal which was not previously provided to Parent.

     (c) Immediately following the execution of this Agreement, (i) the Company shall, and shall cause its Subsidiaries and its and their respective officers, directors and employees, and shall use its reasonable best efforts to cause its and their respective Representatives to, immediately cease and terminate any discussions existing as of the date of this Agreement between the Company or any of its Subsidiaries or any of their respective officers, directors, employees or Representatives and any person (other than Parent) that relate to any Acquisition Proposal, and (ii) the Company shall, and shall use its reasonable best efforts to cause its Representatives to, cause to be returned or destroyed all confidential information provided by or on behalf of the Company or any Subsidiary to such person.

     (d) Except as otherwise provided in Section 5.4(e), neither the Board of Directors of the Company nor any committee thereof may (i) withhold, withdraw or modify, or publicly propose to withhold, withdraw or modify, the Company Recommendation in a manner adverse to Parent, or (ii) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Acquisition Proposal (any action described in this Section 5.4(d), a “Change of Recommendation”).

     (e) Notwithstanding anything in this Agreement to the contrary, with respect to (i) an Intervening Event or (ii) an Acquisition Proposal, the Board of Directors of the Company may at any time prior to receipt of the Company Stockholder Approval, make a Change of Recommendation and/or terminate this Agreement pursuant to Section 7.1(h), if (and only if): (A) in the case of (ii) above, (x) an Acquisition Proposal (that did not result from a breach of Section 5.4(a)) is made to the Company by a third party, and such Acquisition Proposal is not withdrawn; (y) the Company’s Board of Directors determines in good faith after consultation with its financial advisors and outside legal counsel that such Acquisition Proposal constitutes a Superior Offer; and (z) the Company’s Board of Directors determines to terminate this Agreement pursuant to Section 7.1(h), (B) in the case of (i) above, following consultation with outside legal counsel, the Company’s Board of Directors determines that the failure to make a Change of Recommendation would be reasonably likely to constitute a breach by the Board of Directors of its fiduciary duties under applicable Laws; (C) in the case of (i) and (ii) above, (x) the Company provides Parent ninety-six (96) hour’s prior written notice of its intention to take such action, which notice shall include the information with respect to such Intervening Event or Superior Offer, as the case may be, that is specified in Section 5.4(b), (y) after providing such notice and prior to making such Change of Recommendation in connection with an Intervening Event or a Superior Offer or taking any action pursuant to Section 7.1(h) with

respect to a Superior Offer, the Company shall negotiate in good faith with Parent during such ninety-six (96) hour period (to the extent that Parent desires to negotiate) to make such revisions to the terms of this Agreement as would permit the Board of Directors of the Company not to effect a Change of Recommendation in connection with an Intervening Event or a Superior Offer or to take such action pursuant to Section 7.1(h) in response to a Superior Offer, and (z) the Board of Directors of the Company shall have considered in good faith any changes to this Agreement offered in writing by Parent and shall have determined in good faith, after consultation with its outside legal counsel and financial advisors, that the event continues to constitute an Intervening Event or that the Superior Offer would continue to constitute a Superior Proposal, in each case if such changes offered in writing by Parent were to be given effect; provided that, for the avoidance of doubt, the Company shall not effect a Change of Recommendation in connection with an Intervening Event or a Superior Offer or take any action pursuant to Section 7.1(h) with respect to a Superior Offer prior to the time that is ninety-six (96) hours after it has provided the written notice required by clause (x) above; provided further, that in the event that the Acquisition Proposal is thereafter modified by the party making such Acquisition Proposal, the Company shall provide written notice of such modified Acquisition Proposal and shall again comply with this Section 5.4(e), except that the Company’s advance written notice obligation shall be reduced to seventy-two (72) hours (rather than the ninety-six (96) hours otherwise contemplated by this Section 5.4(e)) and the time the Company shall be permitted to effect a Change of Recommendation in connection with a Superior Offer or to take action pursuant to Section 7.1(h) with respect to a Superior Offer shall be reduced to the time that is seventy-two (72) hours after it has provided such written notice (rather than the time that is the ninety-six (96) hours otherwise contemplated by this Section 5.4(e)) (but in no event prior to the original ninety-six (96) hour advance notice period).

     (f) As used in this Agreement:

(i)

“Acquisition Proposal” means any bona fide offer, inquiry, proposal or indication of interest, whether or not in writing, received from a third party (other than an offer, inquiry, proposal or indication of interest by Parent or Merger Sub or any of their respective Subsidiaries) relating to any Acquisition Transaction;

(ii)

“Acquisition Transaction” means any transaction or series of transactions (other than those contemplated by Section 5.19) involving: (A) any merger, consolidation, share exchange, recapitalization or business combination involving the Company or any of its material Subsidiaries; (B) any direct or indirect acquisition, sale, issuance or repurchase of securities, tender offer, joint venture, exchange offer or other similar transaction or series of transactions which would result in a person or “group” (as defined in the Exchange Act) of persons having direct or indirect beneficial or record ownership of securities representing more than twenty percent (20%) of the outstanding Company Common Stock; (C) any direct or indirect acquisition of any business or businesses or of assets (including equity interests in any Subsidiary) that constitute or account for twenty percent (20%) or more of the consolidated net revenues, net income or assets (based on the fair market value thereof) of

the Company and its Subsidiaries, taken as a whole; (D) any liquidation or dissolution of the Company or any of its Subsidiaries or the payment of any extraordinary dividend by the Company; or (E) any combination of the foregoing;

(iii)

     Section 5.5. Filings; Other Actions.

     (a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Company shall prepare and file with the SEC the Proxy Statement, and Parent shall prepare and file with the SEC the Form S-4, in which the Proxy Statement will be included as a prospectus. Each of Parent and the Company shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the Merger and the other transactions contemplated hereby. The Company will cause the Proxy Statement to be mailed to the Company’s stockholders, as reasonably practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of Common Units in the Merger, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the

Form S-4 or the Proxy Statement will be made by Parent or the Company, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, delayed or conditioned) and without providing the other party a reasonable opportunity to review and comment thereon. Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Common Units issuable in connection with the Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective affiliates, officers or directors, is discovered by Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the stockholders of the Company.

     (b) The Company shall take all action necessary in accordance with applicable Laws and the Company Organizational Documents to duly give notice of, convene and hold a meeting of its stockholders, to be held as promptly as practicable after the Form S-4 is declared effective under the Securities Act, to consider the adoption of this Agreement and the approval of the transactions contemplated hereby, including the Merger (the “Stockholders’ Meeting”). The Company will, except in the case of a Change of Recommendation, through its Board of Directors, recommend that its stockholders adopt this Agreement and will use reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and to take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NYSE or applicable Laws to obtain such approvals.

     Section 5.6. Equity-Based Awards.

     (a) The Company shall cause each option to purchase shares of Company Common Stock or stock appreciation right relating to Company Common Stock granted under a Company Benefit Plan that provides for equity-based compensation (each such Company Benefit Plan, a “Company Stock Plan”) that is outstanding immediately prior to the Effective Time (a “Company Stock Award”) to become vested and exercisable prior to the Effective Time and shall, in accordance with the terms of the applicable Company Stock Plan, provide notice to all holders of Company Stock Awards that any Company Stock Award not exercised prior to the Effective Time shall be cancelled and terminate upon the Effective Time. In consideration of such cancellation and termination of Company Stock Awards, the Company shall pay to each holder of a Company Stock Award within five business days following the Effective Time an amount, less applicable withholding Taxes, in cash with respect to each share of Company Common Stock subject to the Company Stock Award equal to (i) the Per Share Cash Consideration minus (ii) the per share exercise price or strike price of the Company Stock Award. If Parent determines the consent of a holder of a Company Stock Award is required to

effectuate the termination of any Company Stock Award, then the Company shall (i) use its reasonable best efforts to obtain such consent from the holder of such Company Stock Award for no additional consideration, except as approved by Parent in advance and (ii) shall make any amendments to the terms of the Company Stock Plans or awards thereunder that may be necessary or advisable to give effect to the termination of such Company Stock Awards, subject to the advance approval of Parent which approval shall not be unreasonably withheld. The Company shall require the holder of any Company Stock Award exercised prior the Effective Time to satisfy any withholding obligation with respect to such Company Stock Award in accordance with the terms of the applicable Company Stock Plan and award agreement.

     (b) Each award of restricted Company Common Stock granted under a Company Stock Plan that is outstanding immediately prior to the Effective Time (the “Restricted Shares”) shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, vest and the restrictions with respect thereto shall lapse, and each share of Company Common Stock subject to such grant of Restricted Shares shall be converted into cash, Common Units or a combination of cash and Common Units in accordance with Section 2.1, depending on whether the holder of such Restricted Shares makes a Cash Election or a Common Unit Election and subject to the terms and conditions of Section 2.1. Unless the holder of such Restricted Shares shall have remitted to the Company the amount required to be withheld with respect to the vesting and lapse of restrictions on the Restricted Shares under the Code or any provision of state, local or foreign tax Law, the consideration to be received by such holder pursuant to Section 2.1 shall be reduced by the amount required to be deducted and withheld with respect to the vesting and lapse of such restrictions on the Restricted Shares. Such reduction shall come first from the cash portion of the consideration payable to the holder of the Restricted Shares under Section 2.1, if any, and if there is no cash portion of such consideration or if the cash portion is not sufficient to satisfy the amount required to be deducted and withheld with respect to vesting and lapse of such restrictions on the Restricted Shares, then the number of Common Units to be received by the holder of such Restricted Shares pursuant to Section 2.1 shall be reduced by a number of Common Units (rounded up to the nearest whole unit with cash payable in respect of the resulting fractional unit) equal to (i) the amount (or additional amount, as the case may be) required to be deducted and withheld with respect to the vesting and lapse of such restrictions on the Restricted Shares, divided by (ii) the closing price of one Common Unit on the New York Stock Exchange on the day prior to the Closing Date.

     (c) The Company shall cause each unvested award of restricted share units, performance shares or phantom shares with respect to shares of Company Common Stock under a Company Stock Plan that is outstanding immediately prior to the Effective Time (a “Company RSU”) to become fully vested, and the Company shall, within five business days following the Effective Time pay to the holder thereof, with respect to each share of Company Common Stock subject to such outstanding Company RSU (giving effect to the acceleration of vesting contemplated by this Section 5.6(c)) a lump sum cash payment, less any applicable withholding Taxes, equal to the greater of (i) the Per Share Cash Consideration and (ii) the product of the Exchange Ratio multiplied by the closing price of one Common Unit on the NYSE on the Closing Date, as reported in the Wall Street Journal or such other source as may be determined by Parent.

     (d) The Company shall use its reasonable best efforts to take any actions reasonably necessary to effectuate the transactions contemplated by this Section 5.6. Prior to the Effective

Time, the Company shall deliver to the holders of the Company Stock Awards and Company RSUs notices, in form and substance reasonably acceptable to Parent, setting forth such holders’ rights pursuant to this Agreement.

     Section 5.7. Employee Matters.

     (a) Parent shall cause the Surviving Corporation and each of its Subsidiaries, for the period commencing at the Effective Time and ending on the first anniversary thereof, to maintain for the individuals employed by the Company or any of its Subsidiaries at the Effective Time (the “Current Employees”) compensation and benefits that are substantially comparable in the aggregate to the compensation and benefits (i) provided to Current Employees as a group immediately prior to the Effective Time (excluding, for this purpose, equity-based compensation and participation in a defined-benefit pension plan unless such participation is mandated by the terms of a collective bargaining or other similar agreement between the Company or one of its Subsidiaries and an employee representative) or (ii) provided to similarly situated employees of Parent and its Subsidiaries.

     (b) Parent will cause the Surviving Corporation to provide credit for each Current Employees length of service with the Company and its Subsidiaries prior to the Effective Time for eligibility, vesting and benefits accrual purposes under any employee benefit plans of the Surviving Corporation and its Subsidiaries to the same extent as such service was recognized under a similar Company Benefit Plan; provided, that such prior service credit shall not be required to the extent it results in a duplication of benefits. Parent shall use commercially reasonable efforts to cause each health plan of Parent in which any Current Employee participates following the Closing to (i) waive any pre-existing condition limitation for any condition for which such Current Employee would have been entitled to coverage under the corresponding Company Benefit Plan prior to the Effective Time and (ii) honor co-payments made, and deductibles satisfied, by such Current Employee prior to the Effective Time. For purposes of this Agreement, “Benefit Plans” means, with respect to any entity, any compensation or employee benefit plans, programs, policies, agreements or other arrangements, whether or not “employee benefit plans” (within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), whether or not subject to ERISA, including bonus, cash or equity-based incentive, deferred compensation, stock purchase, health, medical, dental, disability, accident, life insurance, or vacation, paid time off, perquisite, fringe benefit, severance, change of control, retention, employment, separation, retirement, pension, or savings, plans, programs, policies, agreements or arrangements for the benefit of current or former directors, officers or employees of such entity or any of its Subsidiaries or any dependant or beneficiary thereof.

     (c) If requested by Parent, subject to the terms of any such Benefit Plan, the Company’s Board of Directors shall adopt resolutions, in form and substance reasonably acceptable to Parent, terminating, effective at least one day prior to the Closing Date (the “ERISA Effective Date”), any Company Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement (a “401(k) Plan”). Prior to the ERISA Effective Date, the Company shall provide Parent with executed resolutions of its Board of Directors authorizing such termination and amending any such 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws.

The Company shall also take such other actions in furtherance of the termination of each 401(k) Plan as Parent may reasonably require, including such actions as Parent may require prior to the Effective Time to support Parent obtaining a determination letter with respect to the termination of each 401(k) Plan following the ERISA Effective Date. In addition, if requested by Parent, the Company shall take such actions as may be necessary to eliminate, as of no later than immediately prior to the Effective Time, from any 401(k) Plan or other retirement plan, any investment fund, election or alternative that provides for an investment directly in shares of Company Common Stock.

     (d) Nothing in this Section 5.7 shall be construed as an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment or termination of any Benefit Plan. Nothing in this Section 5.7 shall limit the right of Parent, the Surviving Corporation or any of their Subsidiaries to terminate the employment of any Current Employee at any time, subject to any rights to severance or other separation benefits accrued as of the applicable termination date under a Company Benefit Plan. Without limiting the generality of Section 8.10, the provisions of this Section 5.7 are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other person shall be a third-party beneficiary of this Agreement, and nothing herein shall be construed as an amendment to any Parent Benefit Plan, Company Benefit Plan or other compensation or benefit plan or arrangement for any purpose.

     Section 5.8. Regulatory Approvals; Reasonable Best Efforts.

     (a) Subject to the terms and conditions set forth in this Agreement, each of the parties hereto shall use its reasonable best efforts (subject to, and in accordance with, applicable Law) to take, or cause to be taken, promptly all actions, and to do, or cause to be done, promptly and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Merger and the other transactions contemplated by this Agreement, including: (i) the obtaining of all necessary actions or nonactions, waivers, consents and approvals, including the Company Approvals and the Parent Approvals, from Governmental Entities and the making of all necessary registrations and filings and the taking of all steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties other than any Governmental Entity (including consents necessary in connection with the merger of CrossCountry Energy, LLC with and into a subsidiary of Parent and thereafter a subsidiary of ETP), (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any Governmental Entity vacated or reversed, and (iv) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement. In the event that any litigation, administrative or judicial action or other proceeding is commenced challenging the Merger or any of the proposed transactions, each of the Company, Parent and Merger Sub shall cooperate with each other and use its respective reasonable best efforts to contest and resist any such litigation, action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement.

     (b) Subject to the terms and conditions herein provided and without limiting the foregoing, the Company and Parent shall (i) as promptly as practicable (and in any event not more than ten business days) after the date hereof, make their respective filings and thereafter make any other required submissions under the HSR Act, (ii) use reasonable best efforts to cooperate with each other in (A) determining whether any filings are required to be made with, or consents, permits, authorizations, waivers or approvals are required to be obtained from, any third parties or other Governmental Entities in connection with the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, (B) timely making all such filings and timely seeking all such consents, permits, authorizations or approvals, (C) assuring that all such filings are in material compliance with the requirements of applicable Regulatory Laws, and (D) making available to the other party such information as the other party may reasonably request in order to respond to information requests by any relevant Governmental Entity, (iii) use reasonable best efforts to take, or cause to be taken, all other actions and do, or cause to be done, all other things advisable to consummate and make effective the transactions contemplated hereby, and (iv) subject to applicable legal limitations and the instructions of any Governmental Entity, keep each other apprised of the status of matters relating to the completion of the transactions contemplated thereby, including promptly furnishing the other with copies of notices or other communications, filings or correspondence (or memoranda setting forth the substance thereof) between the Company or Parent, or any of their respective Subsidiaries, and any third party and/or any Governmental Entity (or members of their respective staffs) with respect to such transactions. The Company and Parent shall use their respective reasonable best efforts to file applications for the FERC Approval, the MDPU Approval, the MPSC Approval, the FCC Approval and any other filings, determined to be required as promptly as practicable after the date hereof, but in no event later than thirty days after the date hereof, and shall make such filings jointly if appropriate. Prior to transmitting any material to any Governmental Entity (or members of their respective staffs), the Company and Parent shall permit counsel for the other party a reasonable opportunity to review and provide comments thereon, and consider in good faith the views of the other party in connection with, any proposed written communication to any Governmental Entity (or members of their respective staffs) to the extent permitted by Law. Each of the Company and Parent agrees not to participate in any meeting or discussion, either in person or by telephone, with any Governmental Entity in connection with the proposed transactions unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity or by Law, gives the other party the opportunity to attend and participate.

     (c) In furtherance and not in limitation of the foregoing, each of Parent, Merger Sub and the Company shall use their reasonable best efforts to obtain the Requisite Regulatory Approvals, including (i) responding to and complying with, as promptly as reasonably practicable, any request for information regarding the transactions from any relevant Governmental Entity (including responding to any “second request” for information under the HSR Act as promptly as reasonably practicable); (ii) ensuring the prompt expiration of any applicable waiting period and clearance or approval by any such relevant Governmental Entity, including defense against, and the resolution of, any objections or challenges, in court or otherwise, by any relevant Governmental Entity preventing consummation of the transactions; and (iii) assisting and cooperating with the other party in doing all things necessary, proper or advisable to consummate and make effective the transactions, under any applicable Regulatory Law with each relevant Governmental Entity. In the event the parties, despite their reasonable

best efforts, have not obtained clearance or approval of the transactions from any relevant Governmental Entity and/or resolved any objections or challenges by any relevant Governmental Entity preventing consummation of the transactions by the Closing Date, the Closing Date shall automatically be extended for an additional three months, and thereafter shall be extended for any additional periods as agreed by both Company and Parent.

     (d) Parent agrees to take, or cause to be taken, any and all steps and to make, or cause to be made, any and all undertakings necessary to resolve such objections, if any, that a Governmental Entity may assert under Regulatory Laws with respect to the transactions contemplated hereby, and to avoid or eliminate each and every impediment under Regulatory Laws that may be asserted by any Governmental Entity with respect to the Merger so as to enable the Closing to occur (i) as to the Requisite Regulatory Approvals related to the HSR Act, the Clayton Act, the Sherman Act or the Federal Trade Commission Act (the “Antitrust Approvals”), no later than the time at which all Requisite Regulatory Approvals other than those related to the Antitrust Approvals are achieved and (ii) as to Requisite Regulatory Approvals other than those related to the Antitrust Approvals, as promptly as reasonably practicable and in any event no later than the End Date, including in each case taking any action (including any action that limits Parent’s freedom of action, ownership or control with respect to, or its ability to retain or hold, any of the businesses, assets, product lines or properties of Parent or Company) as may be required in order to avoid the commencement of any action to prohibit the merger, or, in the alternative, to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any action seeking to prohibit the merger; provided, however, that notwithstanding anything in this Section 5.8 to the contrary, Parent shall not be required to take, or cause to be taken, any such action to obtain the MDPU Approval or the MPSC Approval to the extent that such action would require Parent, Merger Sub or the Company to take, or cause to be taken, any action with respect to any of the assets, businesses or product lines of the Company or any of its Subsidiaries, or of Parent or any of its Subsidiaries, or any combination thereof, if such action would result in a material adverse effect on or with respect to the business, financial condition or continuing results of operations of Parent and its Subsidiaries (including the Surviving Corporation), taken as a whole (assuming Parent and its Subsidiaries (including the Surviving Corporation), taken as a whole were an entity with the assets, liabilities and revenues of an entity the size of the Company and its Subsidiaries, taken as a whole). Subject to the provisions of this Section 5.8, Parent shall have sole discretion in determining the scope of undertakings to be taken, including the scope of assets to be divested or held separate, or the conduct to be restricted, in order to meet the obligations of this Paragraph; provided, however, any undertaking pursuant to this Paragraph shall be conditioned on closing of the transactions in this Agreement. Further, Company shall not, without the prior written consent of Parent, publicly or before any governmental entity or other third party commit to or effect, by consent decree, hold separate order or otherwise, any sale, divestiture, disposition, prohibition or limitation or other action of a type described in this agreement. For purposes of this Section 5.8(d), ETP and Regency Energy Partners LP, a Delaware limited partnership (“Regency”), and their respective Subsidiaries, shall be deemed to be Subsidiaries of Parent.

     (e) Parent and the Company and each of their respective Subsidiaries shall not take any action with the intention to, or that could reasonably be expected to, hinder or delay the obtaining of clearance or any necessary consent of any Governmental Entity under any Regulatory Law or the expiration of the required waiting period under any Regulatory Law.

     (f) Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 5.8 shall limit a party’s right to terminate this Agreement pursuant to Section 7.1(b) or Section 7.1(c) so long as such party has, prior to such termination, complied with its obligations under this Agreement, including this Section 5.8.

     (g) As used in this Agreement, “Regulatory Law” means the Sherman Act of 1890, the Clayton Antitrust Act of 1914, the HSR Act, the FPA, the NGA, the NGPA, the ICA, the PUHCA, the Communications Act of 1934, as amended, state laws governing local distribution companies in the States of Massachusetts and Missouri and all other federal, state or foreign statutes, rules, regulations, orders, decrees, administrative and judicial doctrines and other Laws, including any antitrust, competition or trade regulation Laws, that are designed or intended to (i) prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening competition through merger or acquisition or (ii) protect the national security or the national economy of any nation.

     Section 5.9. Takeover Statutes. If any Takeover Law may become, or may purport to be, applicable to the Merger, the Support Agreements or any other transactions contemplated hereby, each of the Company and Parent shall grant such approvals and take such actions as are reasonably necessary so that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby.

     Section 5.10. Public Announcements. Except (a) following any Change of Recommendation or (b) with respect to action taken by the Company or its Board of Directors pursuant to, and in accordance with, Section 5.4 so long as this Agreement is in effect, the parties shall use reasonable best efforts to consult with each other before issuing, and provide each other the reasonable opportunity to review and comment upon, any press release or any public announcement primarily relating to this Agreement or the transactions contemplated hereby. Parent and the Company agree to issue a mutually acceptable initial joint press release announcing this Agreement.

     Section 5.11. Indemnification and Insurance.

     (a) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company or its Subsidiaries as provided in their respective certificates of incorporation or by-laws or other organization documents or in any agreement to which the Company or any of its Subsidiaries is a party, shall survive the Merger and shall continue in full force and effect. For a period of six years from the Effective Time, Parent and the Surviving Corporation shall maintain in effect the exculpation, indemnification and advancement of expenses provisions of the Company’s and any of its Subsidiary’s certificate of incorporation and by-laws or similar organization documents in effect immediately prior to the Effective Time or in any indemnification agreements of the Company or its Subsidiaries with any of their respective directors, officers or employees in effect immediately prior to the Effective Time, and shall not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former directors, officers or employees of the

Company or any of its Subsidiaries; provided, however, that all rights to indemnification in respect of any Action pending or asserted or any claim made within such period shall continue until the disposition of such Action or resolution of such claim. From and after the Effective Time, Parent shall assume, be jointly and severally liable for, and honor, guaranty and stand surety for, and shall cause the Surviving Corporation and its Subsidiaries to honor and perform, in accordance with their respective terms, each of the covenants contained in this Section 5.11 without limit as to time.

     (b) The Surviving Corporation shall, to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current and former director, officer or employee of the Company or any of its Subsidiaries and each person who served as a director, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise if such service was at the request or for the benefit of the Company or any of its Subsidiaries (each, together with such person’s heirs, executors or administrators, an “Indemnified Party”), in each case against any costs or expenses (including advancing attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by applicable Law; provided, however, that the Person to whom expenses are advanced provides an undertaking, if and only to the extent required by Delaware law, to repay such advances if it is ultimately determined that such person is not entitled to indemnification), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (an “Action”), arising out of, relating to or in connection with any action or omission by them in their capacities as such occurring or alleged to have occurred whether before or after the Effective Time (including acts or omissions in connection with such persons serving as an officer, director or other fiduciary in any entity if such service was at the request or for the benefit of the Company). In the event of any such Action, the Surviving Corporation shall cooperate with the Indemnified Party in the defense of any such Action.

     (c) For a period of six years from the Effective Time, Parent shall cause to be maintained in effect the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the Effective Time by the Company and its Subsidiaries with respect to matters arising on or before the Effective Time; provided, however, that Parent shall not be required to pay annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverages required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount.

     (d) Parent shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any indemnified party in enforcing the indemnity and other obligations provided in this Section 5.11.

     (e) The rights of each indemnified party hereunder shall be in addition to, and not in limitation of, any other rights such indemnified party may have under the certificate of incorporation or by-laws or other organization documents of the Company or any of its

Subsidiaries or the Surviving Corporation, any other indemnification arrangement, the DGCL or otherwise.

     (f) In the event Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations of such party set forth in this Section 5.11.

     (g) The obligations of Parent and the Surviving Corporation under this Section 5.11 shall not be terminated, amended or modified in any manner so as to adversely affect any indemnified party (including their successors, heirs and legal representatives) to whom this Section 5.11 applies without the consent of such Indemnified Parties (it being expressly agreed that the Indemnifying Parties to whom this Section 5.11 applies shall be third party beneficiaries of this Section 5.11, and this Section 5.11 shall survive consummation of the Merger and shall be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives against Parent and the Surviving Corporation and their respective successors and assigns.

     Section 5.12. Control of Operations. Without in any way limiting any party’s rights or obligations under this Agreement, the parties understand and agree that (a) nothing contained in this Agreement shall give Parent or the Company, directly or indirectly, the right to control or direct the other party’s operations prior to the Effective Time and (b) prior to the Effective Time, each of the Company and Parent shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

     Section 5.13. Certain Transfer Taxes. Any liability arising out of any real estate transfer Tax with respect to interests in real property owned directly or indirectly by the Company or any of its Subsidiaries immediately prior to the Merger, if applicable and due with respect to the Merger, shall be borne by the Surviving Corporation and expressly shall not be a liability of stockholders of the Company.

     Section 5.14. Section 16 Matters. Prior to the Effective Time, Parent and the Company shall take all such steps as may be required to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) or acquisitions of Common Units (including derivative securities with respect to Common Units) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

     Section 5.15. Agreed Tax Treatment. The parties to this Agreement intend that, with respect to holders of Company Common Stock receiving Common Units as Merger Consideration, the Merger qualify under Section 721(a) of the Code with respect to holders of Company Common Stock to the extent they receive Common Units as Merger Consideration;

provided however, this result may not apply to the extent such holders receive money or other property, other than an operating cash flow distribution (as such term is defined in Treasury regulation section 1.707-4), from Parent on any date through and including the second anniversary of the Closing. Each party hereto agrees to file all federal (and, to the extent applicable, state and local) income tax returns reporting the Merger in a manner consistent with such treatment. Provided the opinion conditions contained in Section 6.2(e) and Section 6.2(f) have been satisfied, Parent shall file the opinions described in Section 6.2(e) and Section 6.2(f) with the SEC by a post-effective amendment to the Form S-4 promptly following the Closing, unless opinions issued to the Company and Parent and addressing the qualification of the Merger (in similar form to those opinions described in Section 6.2(e) and Section 6.2(f)) were previously filed with the SEC.

     Section 5.16. Tax Representation Letters. Parent shall use its reasonable best efforts to deliver to Bingham McCutchen LLP and Latham & Watkins LLP, counsel to Parent (collectively “Parent’s Counsel”), and Roberts & Holland LLP and Locke Lord Bissell & Liddell, LLP, counsel to the Company (collectively the “Company’s Counsel”), a “Tax Representation Letter,” dated as of the Closing Date (and, if requested, dated as of the date the Form S-4 shall have been declared effective by the SEC) and signed by an officer of Parent and Merger Sub, containing representations of Parent and Merger Sub, and the Company shall use its reasonable best efforts to deliver to Parent’s Counsel and the Company’s Counsel a “Tax Representation Letter,” dated as of the Closing Date (and, if requested, dated as of the date the Form S-4 shall have been declared effective by the SEC) and signed by an officer of the Company, containing representations of the Company, in each case (notwithstanding Section 3.24 and Section 4.23) as shall be reasonably necessary or appropriate to enable the Company’s Counsel to render the opinions described in Section 6.2(f) and Parent’s Counsel to render the opinions described in Section 6.2(e).

     Section 5.17. NYSE Listing. Parent shall use its reasonable efforts to cause the Common Units to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Closing Date.

     Section 5.18. Financing and Financing Assistance.

     (a) Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, advisable or proper to consummate and obtain the Financing on the terms and conditions described in the Commitment Letter (or on revised terms that are not materially adverse to Parent as compared to the terms and conditions described in the Commitment Letter and do not contain any provisions which would reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the transactions contemplated by this Agreement, including any modified or additional conditions to the closing of such Financing), including using reasonable best efforts to (i) maintain in effect the Commitment Letter, (ii) satisfy on a timely basis all conditions to the funding of the Financing set forth in the Commitment Letter, (iii) enforce the terms of the Commitment Letter and (iv) negotiate and enter into definitive agreements with respect thereto on the terms and conditions contemplated by the Commitment Letter (including after giving effect to any “market flex” provisions set forth in the Fee Letter executed in connection with the Financing). Parent shall not, and shall not permit Merger Sub to, agree to or permit any

amendment, replacements, supplement or other modification of, or waive any of its material rights under, the Commitment Letter without the Company’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed); provided that Parent and Merger Sub may (x) enter into any amendment, replacement, supplement or other modification to or waiver of any provision of the Commitment Letter that does not contain any provisions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the transactions contemplated by this Agreement; and (y) amend the Commitment Letter to add lenders, lead arrangers, book runners, syndication agents or similar entities who had not executed the Commitment Letter as of the date of this Agreement so long as any such addition would not reasonably be expected to prevent, materially hinder or materially delay the consummation of the Financing or the transactions contemplated by this Agreement or the availability of the Financing under the Commitment Letter. Parent shall exercise its option to extend the commitment to provide the Financing in accordance with the terms of the Commitment Letter if it becomes necessary to ensure that the Financing is available at Closing.

     (b) In the event any portion of the Financing becomes unavailable on the terms and conditions described in or contemplated by the Commitment Letter (including after giving effect to the “market flex” provisions set forth in the Fee Letter executed in connection with the Financing) for any reason, Parent shall, in consultation with the Company, use its reasonable best efforts to arrange to obtain, as promptly as practicable following the occurrence of such event, alternative financing from the same or alternative sources (the “Alternative Financing”) in an amount sufficient to enable Parent to fund the payment of the cash component of the Merger Consideration, which Alternative Financing would not contain any provisions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the transactions contemplated by this Agreement, including any conditions to the closing of such Financing that are materially less favorable to Parent than the conditions to closing in the Commitment Letter (as set forth therein immediately prior to such Alternative Financing). If an Alternative Financing is required in accordance with this Section 5.18(b), Parent shall obtain, and when obtained, provide the Company with a copy of, a new financing commitment that provides for such Alternative Financing, and thereafter the “Commitment Letter” as defined herein shall refer to such financing commitment in respect of the Alternative Financing.

     (c) Prior to the Closing, the Company shall use its reasonable best efforts to provide to Parent and Merger Sub, and shall use its reasonable best efforts to cause its Subsidiaries and the respective officers, employees, agents and representatives of the Company and its Subsidiaries to, provide to Parent and Merger Sub cooperation reasonably requested by Parent that is necessary or reasonably required in connection with the Financing or any other financing that may be arranged by Parent or ETP (together with the Financing, the “Financings”, and the sources of the Financings, the “Financing Sources”), consisting of the following: (i) using reasonable best efforts to cause the senior officers and other representatives of the Company and its Subsidiaries, including without limitation Citrus Corp. (the “Company Finance Parties”) to participate in meetings, presentations, road shows, due diligence sessions (including accounting due diligence sessions), drafting sessions and sessions with rating agencies on reasonable advance notice to the extent practicable; (ii) assisting with the preparation of appropriate and customary materials for rating agency presentations, customary debt offering documents and

customary bank information memoranda in connection with the Financings; (iii) using its commercially reasonable efforts to assist with the preparation of any pledge and security documents, any loan agreement, currency or interest hedging agreement, other definitive financing documents on terms reasonably satisfactory to Parent, or other certificates, legal opinions or documents as may be reasonably requested by Parent and usual and customary for transactions of the type contemplated by the Financings, provided that no obligation of any Company Finance Party under any such document or agreement shall be effective until the Effective Time; (iv) using commercially reasonable efforts to facilitate the pledging of collateral, provided that no pledge shall be effective until the Effective Time; (v) using reasonable best efforts to furnish to Parent and Merger Sub and the Financing Sources, as promptly as reasonably practicable, with financial statements regarding the Company Finance Parties as may be reasonably requested by Parent, including all historical financial statements that meet the requirements of Regulation S-X promulgated under the Securities Act and other financial data reasonably required in connection with the Financing, including such financial information that Parent reasonably requires for the preparation of pro-forma financial statements; (vi) providing monthly financial statements to the extent the Company Finance Parties customarily prepare such financial statements within the time such statements are customarily prepared; (vii) executing and delivering (or using reasonable best efforts to obtain from its advisors), and causing the Company Finance Parties to execute and deliver (or use reasonable best efforts to obtain from its advisors), customary certificates, accounting comfort letters (including consents of accountants for use of their audit reports in any financial statements relating to the Financing), legal opinions or other documents and instruments relating to guarantees and other matters ancillary to the Financings as may be reasonably requested by Parent as necessary and customary in connection with the Financings, (viii) providing audited consolidated financial statements of the Company (and any other Company Finance Party that regularly prepares such financial statements) covering the three (3) fiscal years immediately preceding the date of any request therefor for which audited consolidated financial statements are then currently available, unaudited financial statements for any regular quarterly interim fiscal period or periods of the Company (and any other Company Finance Party that regularly prepares such financial statements) ended after the date of the most recent audited financial statements and at least 45 days prior to any request therefor (within 45 days after the end of each such period), and (ix) requesting that its independent accountants cooperate with and assist Parent and ETP in preparing customary and appropriate information packages and offering materials as the parties to the Financings may reasonably request for use in connection with the Financings, in obtaining third party consents in connection with such financing, and, if applicable, in extinguishing existing indebtedness of the Company Finance Parties and releasing liens securing such indebtedness, in each case to take effect at the Effective Time; provided, that the cooperation and actions required by the Company Finance Parties pursuant to this Section 5.18(c) shall not be required to be taken if any such cooperation or act (x) causes any representations or warranties of the Company in this Agreement to be breached, (y) otherwise causes a breach of this Agreement or (z) would cause the Company Finance Parties any material disruption in its business and the reasonable out-of-pocket cost and expense of such cooperation and actions under this Section 5.18(c) shall be borne by the Parent. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be deemed to be in breach of the covenant set forth in this Section 5.18(c) so long as it has acted in good faith to comply with the cooperation and assistance set forth herein. The Company may provide Parent with a written notice indicating

that it has complied with the covenant set forth in this Section 5.18(c) (other than those items that are not capable of being satisfied prior to Closing) which shall be deemed accepted by Parent unless Parent shall object to such determination in writing within 5 business days from receipt of such notice which objection shall specifically identify the area or areas where it believes that the Company Finance Parties have not satisfied its obligations under this Section 5.18(c) (other than those items that are not capable of being satisfied prior to Closing).

     (d) Parent acknowledges and agrees that obtaining the Financing is not a condition to Closing. For the avoidance of doubt, if the Financing has not been obtained, Parent shall continue to be obligated, until such time as the Agreement is terminated in accordance with its terms and subject to the fulfillment or waiver of the condition set forth in Article VI to complete the Merger on the terms contemplated by this Agreement.

     (e) All material non-public information regarding the Company and its Subsidiaries provided to Parent, Merger Sub, ETP and their respective representatives pursuant to Section 5.18(c) shall be kept confidential by them in accordance with the Confidentiality Agreement. The Company hereby consents to the use of all of its and its Subsidiaries’ names and logos in connection with the Financing; provided that such names and logos are used solely in a manner that is not intended to nor is reasonably likely to harm or disparage the Company or any of its Subsidiaries, the reputation or goodwill of the Company or any of its Subsidiaries or any of their assets, including their logos and marks.

     Section 5.19. Citrus Transfer. Assuming all conditions to consummation of Merger have been satisfied or will be satisfied upon the Closing, the Company will assume (and Parent will assign its rights), immediately prior to the Effective Time, the obligations and rights of Parent under the Amended and Restated Merger Agreement (the “ETP Merger Agreement”) attached hereto as Exhibit B and perform Parent’s obligations under the ETP Merger Agreement, including consummation of the transactions contemplated thereby (the “Citrus Transfer”), if all conditions to consummation set forth in Sections 6.1 and 6.2 of the ETP Merger Agreement have been satisfied or will be satisfied at closing thereof. Provided that the Company has complied with its obligations under this Section 5.19 in all material respects, the consummation of the Citrus Transfer shall not otherwise be a condition to consummation of the Merger.

ARTICLE VII.

TERMINATION

     Section 7.1. Termination or Abandonment. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and abandoned at any time prior to the Effective Time, whether before or after any approval of the Merger by the stockholders of the Company:

     (a) by the mutual written consent of the Company and Parent;

     (b) by either Parent or the Company if the Merger shall not have been consummated on or prior to June 30, 2012 (the “End Date”), provided, however, that if all of the conditions to Closing, other than the condition set forth in Section 6.1(c), shall have been satisfied or shall be capable of being satisfied at such time, the End Date may be extended by Parent or the Company from time to time by written notice to the other party up to a date not beyond December 31, 2012, the latest of any of which dates shall thereafter be deemed to be the End Date; and provided, further, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to a party if the failure of the Closing to occur by such date shall be due to the material breach by such party of any representation, warranty, covenant or other agreement of such party set forth in this Agreement;

     (c) by either the Company or Parent if an injunction shall have been entered permanently restraining, enjoining or otherwise prohibiting the consummation of the Merger and such injunction shall have become final and non-appealable; provided that the party seeking to

terminate this Agreement pursuant to this Section 7.1(c) shall have used its reasonable best efforts to remove such injunction to the extent such party is required to use its reasonable best efforts pursuant to this Agreement;

     (d) by either the Company or Parent if the Stockholders’ Meeting (including any adjournments or postponements thereof) shall have concluded and the Company Stockholder Approval shall not have been obtained;

     (e) by the Company, if Parent shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) would result in a failure of a condition set forth in Section 6.1 or Section 6.2 and (ii) by its nature, cannot be cured prior to the End Date or, if by its nature such breach or failure is capable of being cured by the End Date, Parent does not diligently attempt or ceases to diligently attempt to cure such breach or failure after receiving written notice from the Company describing such breach or failure in reasonable detail (provided that the Company is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

     (f) by Parent, if the Company shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) would result in a failure of a condition set forth in Section 6.1 or Section 6.3 and (ii) by its nature, cannot be cured prior to the End Date or, if by its nature such breach or failure is capable of being cured by the End Date, the Company does not diligently attempt or ceases to diligently attempt to cure such breach or failure after receiving written notice from Parent describing such breach or failure in reasonable detail (provided that Parent is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

     (g) by Parent, (i) prior to the Company Stockholder Approval, in the event of a Change of Recommendation or if the Board of Directors of the Company shall have approved or recommended to its shareholders an Acquisition Transaction, or (ii) the Company shall have willfully and materially breached any of its obligations under Section 5.4; and

     (h) by the Company, prior to obtaining the Company Stockholder Approval and if the Company has complied with its obligations under Section 5.4, in order to enter into a definitive agreement with respect to a Superior Offer; provided that any such purported termination by the Company pursuant to this Section 7.1(h) shall be void and of no force or effect unless the Company pays to Parent the expense reimbursement in accordance with Section 7.3(a) and the Breakup Fee in accordance with Section 7.3(c).

     Section 7.2. Effect of Termination. In the event of termination of this Agreement pursuant to Section 7.1, this Agreement shall terminate (except for the provisions of Section 7.3 and Article VIII), and there shall be no other liability on the part of the Company or Parent to the other except as provided in Section 7.3 and, subject to Section 7.3(h), liability arising out of or the result of, fraud or any willful or intentional breach of any covenant or agreement or willful or intentional breach of any representation or warranty in this Agreement occurring prior to

termination or as provided for in the Confidentiality Agreement, in which case the aggrieved party shall be entitled to all rights and remedies available at law or in equity.

     Section 7.3. Expense Reimbursement; Breakup Fee.

     (a) If this Agreement is terminated (i) by either the Company or Parent pursuant to Section 7.1(d) and (A) prior to such termination, any person (other than Parent or its affiliates) shall have made an Acquisition Proposal, which shall have been publicly announced or disclosed or otherwise communicated to the Company, the Board of Directors of the Company or any Representative of the Company (or any person shall have publicly announced a bona fide intention, whether or not conditional, to make an Acquisition Proposal), and such Acquisition Proposal shall not have been withdrawn prior to such termination and (B) within twelve months after such termination of this Agreement, the Company shall have consummated, or shall have entered into an agreement to consummate (which may be consummated after such twelve-month period), an Acquisition Transaction, (ii) by the Company pursuant to Section 7.1(d), (iii) by Parent pursuant to Section 7.1(f), (iv) by Parent pursuant to Section 7.1(g), or (v) by the Company pursuant to Section 7.1(h), then the Company shall, promptly upon written demand by Parent (and in any event no later than two business days after such written demand is delivered to the Company) reimburse Parent, by wire transfer of same day federal funds to the account specified by Parent, for all out-of-pocket fees and expenses incurred or paid by or on or behalf of Parent and Merger Sub in connection with the Merger or related to the preparation, negotiation, execution and performance of this Agreement, the Commitment Letter, the Fee Letter and the Support Agreements, including all fees and expenses of counsel, financial advisors, accountants, experts, and consultants retained by Parent or Merger Sub, and all commitment and other fees of the financing sources in connection with the Financings, such amount not to exceed $54.0 million.

     (b) If this Agreement is terminated by the Company pursuant to Section 7.1(e) (other than for a failure to cause the Closing to occur as a result of Parent’s failure to obtain the Financing or any Alternative Financing), then Parent shall promptly upon written demand by the Company (and in any event no later than two business days after such written demand is delivered to Parent) reimburse the Company, by wire transfer of same day federal funds to the account specified by the Company, for all out-of-pocket fees and expenses incurred or paid by or on or behalf of the Company in connection with the Merger or related to the preparation, negotiation, execution and performance of this Agreement, including all fees and expenses of counsel, financial advisors, accountants, experts, and consultants retained by the Company, such amount not to exceed $54.0 million.

     (c) If this Agreement is terminated (i) by Parent pursuant to Section 7.1(f), (ii) by Parent pursuant to Section 7.1(g) or (iii) by the Company pursuant to Section 7.1(h), then the Company shall pay to Parent the Breakup Fee (x) within two business days after termination of this Agreement in the case of a termination pursuant to clauses (i) and (ii) above and (y) upon termination of this Agreement, and as a condition to the effectiveness of such termination, in the case of a termination pursuant to clause (iii) above.

     (d) If this Agreement is terminated by the Company or Parent pursuant to Section 7.1(b) or Section 7.1(d) or by Parent pursuant to Section 7.1(f) and (i) prior to the Company

Stockholder Approval, any person (other than Parent or its affiliates) shall have made an Acquisition Proposal which shall have been publicly announced or disclosed or otherwise communicated to the Company, the Board of Directors of the Company or any Representative of the Company (or any person shall have publicly announced a bona fide intention, whether or not conditional, to make an Acquisition Proposal) and such Acquisition Proposal shall not have been withdrawn prior to the Company Stockholder Approval and (ii) within twelve months after such termination of this Agreement, the Company shall have consummated, or shall have entered into an agreement to consummate (which may be consummated after such twelve-month period), an Acquisition Transaction, then the Company shall pay to Parent the Breakup Fee, by wire transfer of same day federal funds to the account specified by Parent, on the date such Acquisition Transaction is consummated, or, if earlier, contemporaneously with or immediately after the entry into of any binding agreement to consummate the Acquisition Transaction.

     (e) If this Agreement is terminated by the Company pursuant to Section 7.1(e) (other than for a failure to cause the Closing to occur as a result of Parent’s failure to obtain the Financing or any Alternative Financing), then Parent shall pay to the Company the Breakup Fee in immediately available funds within two (2) business days after termination of this Agreement.

     (f) Solely for purposes of this Section 7.3, “Acquisition Transaction” shall have the meaning ascribed thereto in Section 5.4, except that all references to twenty-five percent (25%) shall be changed to fifty percent (50%).

     (g) As used in this Agreement, “Breakup Fee” means $181.3 million.

     (h) Upon payment of (i) the Breakup Fee to Parent pursuant to Section 7.3(c) or Section 7.3(d) and any expense reimbursement required pursuant to Section 7.3(a), the Company shall have no further liability with respect to this Agreement or the transactions contemplated hereby to Parent or its stockholders and (ii) upon payment of the Breakup Fee to the Company pursuant to Section 7.3(e) and any expense reimbursement required pursuant to Section 7.3(b), Parent shall have no further liability pursuant to this Agreement or the transactions contemplated hereby to the Company or its stockholders; provided, that nothing herein shall release any party from liability arising out of or the result of, fraud or any willful or intentional breach of any covenant or agreement or willful or intentional breach of any representation or warranty in this Agreement and provided further that whether or not the Breakup Fee has been paid, nothing in this Agreement shall release Parent from any liabilities in the event that (i) all of the conditions to Closing set forth in Section 6.1 and Section 6.3 have been satisfied (other than conditions that can only be satisfied as of the Closing) and Parent does not cause the Closing to occur or (ii) the Closing does not occur as a result of a breach by Parent of its obligations under Section 5.8. The parties acknowledge and agree that in no event shall the Company or Parent be required to pay the Breakup Fee, as applicable, on more than one occasion. In addition, the parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement and are not a penalty, and that, without these agreements, neither party would enter into this Agreement. If the Company or Parent, as the case may be, fails to pay promptly the amounts due pursuant to this Section 7.3, the Company or Parent, as the case may be, will also pay to Parent or the Company, as the case may be, such party’s reasonable costs and expenses (including legal fees and expenses) in connection with any action, including the filing of any lawsuit or other legal action, taken to collect payment, together with interest on

the unpaid amount under this Section 7.3, accruing from its due date, at an interest rate per annum equal to two percentage points in excess of the prime commercial lending rate quoted by The Wall Street Journal. Any change in the interest rate hereunder resulting from a change in such prime rate will be effective at the beginning of the date of such change in such prime rate.

     Section 8.9. Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

     Section 8.10. Entire Agreement. This Agreement together with the exhibits hereto, schedules hereto and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof and thereof, and this Agreement is not intended to grant standing to any person other than the parties hereto. In connection with the execution of this Agreement, Parent and the Company hereby waive the applicability of the first paragraph on page four of the Confidentiality Agreement to Parent and its affiliates from and after the date hereof.

     Section 8.11. Amendments; Waivers. At any time prior to the Effective Time, any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the Company, Parent and Merger Sub or, in the case of a waiver, by the party against whom the waiver is to be effective;

provided, however, that after receipt of Company Stockholder Approval, if any such amendment or waiver shall by applicable Law or in accordance with the rules and regulations of the NYSE require further approval of the stockholders of the Company, the effectiveness of such amendment or waiver shall be subject to the approval of the stockholders of the Company. Notwithstanding the foregoing, no failure or delay by the Company or Parent in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

     Section 8.12. Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever. The table of contents to this Agreement is for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

     Section 8.13. No Third Party Beneficiaries. Each of Parent, Merger Sub and the Company agrees that (a) their respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the other party hereto, in accordance with and subject to the terms of this Agreement, and (b) except for Section 5.11, and except for Section 8.6 and the final sentence of Section 8.5 (which are enforceable by each of the Financing Sources and its successors and assigns) this Agreement is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein.

     Section 8.14. Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement, unless the context otherwise requires. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant thereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any statute defined or referred to herein means such statute as from time to time amended, modified or supplemented, including by succession of comparable successor statutes. Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement. All references herein to “the date hereof”, “the date of this Agreement” or similar references shall be deemed to refer to the date of execution of the Original Agreement.

     Section 8.15. Definitions.

general partner on the date hereof (excluding partnerships in which such party or any Subsidiary of such party does not have a majority of the voting interests in such partnership other than ETP which will be deemed a Subsidiary of Parent solely for purposes of Article IV hereof). References in this Agreement (except as specifically otherwise defined) to “affiliates” means, as to any person, any other person which, directly or indirectly, controls, or is controlled by, or is under common control with, such person; provided, however, that (other than for purposes of Section 4.21) the term “affiliate” shall not include ETP, Regency, or any of their respective Subsidiaries. As used in this definition, “control” (including, with its correlative meanings, “controlled by” and “under common control with”) means the possession, directly or indirectly, of the power to direct or cause the direction of management or policies of a person, whether through the ownership of securities or partnership or other ownership interests, by contract or otherwise.
