2.5 Contribution Consideration Adjustment.

(a) The “Contribution Consideration Adjustment Amount” shall be an amount determined as follows:

(i) The Contribution Consideration Adjustment Amount shall be increased by the amount (if any) by which the Net Working Capital of the Acquired Companies on a consolidated basis as of the Closing Date (“Closing Date Net Working Capital”) exceeds $0 (the “Net Working Capital Threshold”);

(ii) The Contribution Consideration Adjustment Amount shall be decreased by the amount (if any) by which the Net Working Capital Threshold exceeds the Closing Date Net Working Capital;

(iii) The Contribution Consideration Adjustment Amount shall be decreased by the amount (if any) by which the Long-Term Debt of the Acquired Companies on a consolidated basis as of the Closing Date (“Closing Date Long-Term Debt”) exceeds $0 (the “Long-Term Debt Threshold”);

(iv) The Contribution Consideration Adjustment Amount shall be increased by the amount (if any) by which the Capex Amount exceeds the Base Capex Amount;

(v) The Contribution Consideration Adjustment Amount shall be decreased by the amount (if any) by which the Base Capex Amount exceeds the Capex Amount; and

(vi) The Contribution Consideration Adjustment Amount shall be decreased by the Estimated Preceding Quarter Distribution Amount (if any) and the Estimated Pro Rata Closing Quarter Distribution Amount, in each case as determined in accordance with Sections 2.6(a) or (b).

(b) Not later than ten (10) Business Days prior to the Closing Date, the Contributor shall prepare and deliver to Regency a preliminary settlement statement (the “Estimated Adjustment Statement”) setting forth (i) an estimated consolidated balance sheet of the Acquired Companies as of the Closing Date, which balance sheet was prepared in accordance with GAAP, applied consistently with the Acquired Companies’ past practices (including its preparation of the Company Financial Statements) (the “Estimated Closing Date Balance Sheet”) based on the most recent financial information of the Acquired Companies reasonably available to the Contributor, (ii) a calculation of the difference, if any, between the Net Working Capital shown on the Estimated Closing Date Balance Sheet (“Estimated Net Working Capital”) and the Net Working Capital Threshold, (iii) a calculation of the difference, if any, between the Long-Term Debt shown on the Estimated Closing Date Balance Sheet (“Estimated Closing Date Long-Term Debt”) and the Long-Term Debt Threshold, (iv) a calculation of the difference, if any, between the estimated Capex Amount and the Base Capex Amount, (v) an estimated calculation of the Estimated Preceding Quarter Distribution Amount, if any, and the Estimated Pro Rata Closing Quarter Distribution Amount; and (vi) an estimated calculation of the Contribution

Consideration Adjustment Amount. The Estimated Adjustment Statement shall be prepared consistent with a methodology agreed to by the Parties for the preparation of the Estimated Adjustment Statement. Regency shall have the right, following Regency’s receipt of the Estimated Adjustment Statement, to object thereto by delivering written notice to the Contributor no later than two Business Days before the Closing Date. To the extent Regency timely objects to the Estimated Adjustment Statement (or any component thereof), Regency and the Contributor shall attempt to resolve their differences; provided that, if Regency and the Contributor are unable to resolve any such dispute prior to the Closing Date, then the Contributor’s calculations as reflected in the Estimated Adjustment Statement shall control for purposes of all payments to be made at Closing. To the extent Regency and the Contributor resolve any of their differences prior to the Closing, then the Parties shall jointly agree on a revised Estimated Adjustment Statement that will control for purposes of the payments to be made at the Closing. The estimated Contribution Consideration Adjustment Amount that controls for purposes of the payments to be made at the Closing is referred to herein as the “Estimated Contribution Consideration Adjustment Amount.” If the Estimated Contribution Consideration Adjustment Amount is (i) a positive number, then the Cash Consideration to be distributed by Regency at Closing shall be increased by the amount of the Estimated Contribution Consideration Adjustment Amount or (ii) a negative number, then the Cash Consideration to be distributed by Regency at Closing shall be reduced by the absolute value of the Estimated Contribution Consideration Adjustment Amount.

(c) As promptly as practicable after the Closing, but in no event later than 45 days following the Closing Date, the Contributor shall prepare and deliver to Regency a statement (the “Final Adjustment Statement”) setting forth (i) a consolidated balance sheet of the Acquired Companies as of the Closing Date, which balance sheet will be prepared using the same accounting methods, policies, practices and procedures used in the preparation of the Estimated Closing Date Balance Sheet (the “Final Closing Date Balance Sheet”) based on the most recent financial information of the Acquired Companies reasonably available to the Contributor, (ii) a calculation of the difference, if any, between the Net Working Capital shown on the Final Closing Date Balance Sheet and Estimated Net Working Capital, (iii) a calculation of the difference, if any, between the Closing Date Long-Term Debt shown on the Final Closing Date Balance Sheet and Estimated Closing Date Long-Term Debt, (iv) a calculation of the difference, if any, between the actual Capex Amount and the estimated Capex Amount, and (v) the final calculation of the Contribution Consideration Adjustment Amount; provided, however, that the calculation of the difference between the Actual Preceding Quarter Distribution Amount and the Estimated Preceding Quarter Distribution Amount and the calculation of the difference between the Actual Pro Rata Closing Quarter Distribution Amount and the Estimated Pro Rata Closing Quarter Distribution Amount shall be determined in accordance with Section 2.6(c) and Section 2.6(d), respectively. The Final Adjustment Statement shall be prepared consistent with the methodology and example agreed to by the Parties for the preparation of the Estimated Adjustment Statement. In order for the Contributor to prepare the Final Closing Date Balance Sheet and the calculations required in the Final Adjustment Statement, Regency and the Acquired Companies shall, and Regency shall cause the Acquired Companies to, (i) permit the Contributor and its Representatives to have reasonable access during normal business hours to the books, records and other documents (including working papers, schedules, financial statements, memoranda, etc.) (the “Books and Records”) of the Acquired Companies, and shall cooperate with the Contributor and its Representatives in seeking to obtain work papers from

Regency and the Acquired Companies, reasonably necessary for the preparation of the Final Closing Date Balance Sheet and such calculations, and provide the Contributor with copies thereof (as reasonably requested by the Contributor) and (ii) provide the Contributor and its Representatives with reasonable access during normal business hours to the Acquired Companies employees and accountants as reasonably requested by the Contributor. At any time during the 30-day period following receipt of the Final Adjustment Statement (the “Review Period”), Regency may deliver to the Contributor a written report containing any changes that Regency proposes be made to the Final Adjustment Statement, accompanied with any such supporting documentation, if available, and describing in reasonable detail the basis for the proposed changes (such written report, an “Objection Notice”). Upon Regency’s request, the Contributor shall provide to Regency and its Representatives such documentation and other data, and, during normal business hours, access to its officers, employees, agents and other personnel as is reasonably necessary to enable Regency and its Representatives to appropriately review the Final Closing Balance Sheet and Final Adjustment Statement. Regency shall be deemed to have waived any rights to object to the Final Adjustment Statement unless Regency delivers an Objection Notice to the Contributor within the Review Period and, if the Review Period expires without Regency so delivering an Objection Notice, then the Final Adjustment Statement shall become final and binding for all purposes of this Agreement. If Regency delivers an Objection Notice to the Contributor during the Review Period, then the Contributor and Regency shall negotiate in good faith to resolve their disagreement and to agree on the amount of the actual Contribution Consideration Adjustment Amount. If the Contributor and Regency cannot reach agreement within 30 days after the date on which Regency delivered such Objection Notice to the Contributor, then the Contributor and Regency shall refer the remaining disputed matters necessary to the final determination of the Contribution Consideration Adjustment Amount to BDO, or if BDO is unable or unwilling to perform its obligations under this Section 2.5(c), such other nationally-recognized independent accounting firm as is mutually agreed on by the Contributor and Regency (the “Accounting Firm”). The Accounting Firm shall, if requested by the Contributor and Regency, resolve any disputes under this Section 2.5(c). Each Party shall deliver simultaneously to the Accounting Firm (i) the Objection Notice and such work papers, invoices and other reports and information relating to the disputed matters as the Accounting Firm may request and (ii) such Party’s proposed resolution of the disputed matters and any materials it wishes to present to justify the resolution it so presents. Each Party shall be afforded the opportunity to discuss the disputed matters with the Accounting Firm. The Accounting Firm shall act as an expert (and not as an arbitrator) for the limited purpose of determining the specific items identified by the Contributor and Regency as being items that are in dispute, and whether and to what extent, if any, the Contribution Consideration Adjustment Amount requires adjustment as a result of the resolution of those disputed matters (applying GAAP consistently with the Acquired Companies’ past practices). The Accounting Firm may not award damages or penalties and shall not have authority to address matters not in dispute between the Contributor and Regency or not necessary to the determination of the final Contribution Consideration Adjustment Amount. The Accounting Firm’s determination shall be made within 30 days after submission of the disputed matters to the Accounting Firm and shall be final and binding on all Parties, without right of appeal. In determining the proper amount of the Contribution Consideration Adjustment Amount, the Accounting Firm shall not increase the Contribution Consideration Adjustment Amount more than the increase proposed by the Contributor nor decrease the Contribution Consideration Adjustment Amount more than the decrease proposed

by Regency, as applicable. Each Party shall each bear its own legal fees and other costs of presenting its case to the Accounting Firm. The Contributor and Regency shall each bear one-half of the costs and expenses of the Accounting Firm incurred in resolving such disputed matters. The Contribution Consideration Adjustment Amount as finally determined pursuant to this Section 2.5(c) shall be referred to as the “Final Contribution Consideration Adjustment Amount.”

(d) Within five days after the earlier of (i) the expiration of the Review Period without delivery of any Objection Notice and (ii) the date on which the Contributor and Regency, or the Accounting Firm, as applicable, finally determine the Final Contribution Consideration Adjustment Amount (A) if the Final Contribution Consideration Adjustment Amount exceeds the Estimated Contribution Consideration Adjustment Amount (such excess, the “Contributor Adjustment Distribution”), Regency shall wire transfer in immediately available funds an amount equal to the Contributor Adjustment Distribution to an account designated by the Contributor and (B) if the Estimated Contribution Consideration Adjustment Amount exceeds the Final Contribution Consideration Adjustment Amount (such excess, the “Regency Adjustment Contribution”), the Contributor shall wire transfer in immediately available funds an amount equal to the Regency Adjustment Contribution to an account designated by Regency.

2.6 Pro Ration of Distributions.

(a) If the Closing occurs after the last day of the calendar quarter (the “Preceding Quarter”) immediately prior to the calendar quarter (the “Closing Quarter”) in which the Closing Date occurs but prior to the Record Date for the distribution in respect of the Preceding Quarter, then at the Closing, the Estimated Contribution Consideration Adjustment Amount (and therefore the Cash Consideration) shall be reduced by (i) an amount equal to the product of (a) the number of Acquired Common Units multiplied by (b) $0.46 (unless prior to the Closing, Regency shall have declared its cash distribution in respect of the Preceding Quarter, in which event such number in this clause (b) shall be the cash distribution amount declared per Regency Common Unit) (such aggregate amount being referred to herein as the “Estimated Preceding Quarter Distribution Amount”) and (ii) an amount equal to the product of (A) the number of Acquired Common Units multiplied by (B) $0.46 multiplied by (C) a fraction, (1) the numerator of which is the number of days in the Closing Quarter commencing on the first day of the Closing Quarter and ending on and including the Closing Date and (2) the denominator of which is the total number of days in the Closing Quarter (such aggregate amount calculated in accordance with this clause (ii) being referred to herein as the “Estimated Pro Rata Closing Quarter Distribution Amount”).

(b) If the Closing occurs after the Record Date for the cash distribution by Regency on its Common Units in respect of the Preceding Quarter, then at the Closing, the Estimated Contribution Consideration Adjustment Amount (and therefore the Cash Consideration) shall be reduced by an amount equal to the Estimated Pro Rata Closing Quarter Distribution Amount, and no adjustment shall be made pursuant to Section 2.6(a).

(c) If the Closing occurs within the period specified in Section 2.6(a), unless the actual declared per unit distribution in respect of the Preceding Quarter is used to determine the

Estimated Preceding Quarter Distribution Amount, then not later than the second Business Day following Regency’s declaration of its cash distribution in respect of the Preceding Quarter, Regency shall prepare and deliver to the Contributor a calculation of the Actual Preceding Quarter Distribution Amount (as defined below). Within two Business Days after such delivery, (i) if the Actual Preceding Quarter Distribution Amount exceeds the Estimated Preceding Quarter Distribution Amount, then the Contributor shall wire transfer in immediately available funds the amount of such excess to an account designated by Regency and (ii) if the Estimated Preceding Quarter Distribution Amount exceeds the Actual Preceding Quarter Distribution Amount, then Regency shall wire transfer in immediately available funds the amount of such excess to an account designated by the Contributor.

(d) Not later than the second Business Day following Regency’s declaration of its cash distribution in respect of the Closing Quarter, Regency shall prepare and deliver to the Contributor a calculation of the Actual Pro Rata Closing Quarter Distribution Amount (as defined below). Within two Business Days of such delivery, (i) if the Actual Pro Rata Closing Quarter Distribution Amount exceeds the Estimated Pro Rata Closing Quarter Distribution Amount, the Contributor shall wire transfer in immediately available funds an amount equal to such excess to an account designated by Regency and (ii) if the Estimated Pro Rata Closing Quarter Distribution Amount exceeds the Actual Pro Rata Closing Quarter Distribution Amount, Regency shall wire transfer in immediately available funds an amount equal to such excess to an account designated by the Contributor.

(e) “Actual Preceding Quarter Distribution Amount” means the product of (i) the number of Acquired Common Units multiplied by (ii) the actual per-unit cash distribution amount declared on the Regency Common Units in respect of the Preceding Quarter.

(f) “Actual Pro Rata Closing Quarter Distribution Amount” means the product of (i) the number of Acquired Common Units multiplied by (ii) the actual per-unit cash distribution amount declared on the Regency Common Units in respect of the Closing Quarter multiplied by (iii) a fraction, (A) the numerator of which is the number of days in the Closing Quarter commencing on the first day of such quarter and ending on and including the Closing Date and (B) the denominator of which is the total number of days in the Closing Quarter.

2.7 Adjustment to Contribution Consideration. All adjustments to the Cash Consideration pursuant to this Agreement and amounts paid pursuant to Section 2.6 shall be deemed to be adjustments to the Final Contribution Consideration.

2.8 Borrowing by Regency; Tax Treatment of Regency Contribution Consideration. Prior to the Closing, but no more than ninety (90) days prior to the Closing, Regency shall incur a new and separate borrowing (which may be in the form of a new credit facility, senior debt or any combination thereof) that will be used by Regency exclusively to pay the Cash Consideration, as adjusted, and other expenses or disbursements directly related to the Closing (the “Regency Debt”) and Regency Subsidiary Guarantor shall enter into the Guarantee of Collection with Regency with respect to the Regency Debt. In the event Regency receives the proceeds from the Regency Debt prior to the Closing, such proceeds shall be deposited and held separate from other cash items of Regency until distributed to Contributor at the time of the Closing. Immediately prior to the effective time of the Closing, PEPL Holdings shall enter into

the Support Agreement with Regency Subsidiary Guarantor pursuant to which PEPL Holdings shall provide contingent residual support to Regency Subsidiary Guarantor (on a nonrecourse basis to Contributor) with respect to Regency Subsidiary Guarantor’s obligations to Regency under the Guarantee of Collection to support the payment of the Regency Debt. The Parties intend that for United States federal income tax purposes (i) the contribution of the Contributed Interests shall be treated as a contribution by Contributor to Regency of the assets of the Company (and the assets of the Subsidiaries of the Company that are also treated as disregarded entities of Contributor) in a transaction consistent with the requirements of Section 721(a) of the Code; (ii) the receipt by Contributor of the Cash Consideration shall be treated as a distribution to Contributor by Regency under Section 731 of the Code; (iii) the distribution of the Cash Consideration to Contributor shall be made out of the proceeds of the Regency Debt and shall qualify as a “debt-financed transfer” under Section 1.707-5(b) of the Treasury Regulations; and (iv) Contributor’s allocable share of the Regency Debt under Sections 1.752-2 and 1.707-5(a)(2)(i) of the Treasury Regulations shall be the allocable amount of the Regency Debt as determined under Section 1.707-5(b)(2) of the Treasury Regulations. Accordingly, such consideration is not expected to be taken into account in determining whether Contributor received money or other consideration for disguised sale purposes. Any Cash Consideration in excess of the amount treated as a “debt-financed transfer” shall be treated (i) as a reimbursement of Contributor’s preformation expenditures with respect to the assets of the Company (and the assets of the Subsidiaries of the Company) within the meaning of Section 1.707-4(d) of the Treasury Regulations to the extent applicable (accordingly, such cash is not expected to be taken into account in determining whether Contributor received money or other consideration for disguised sale purposes), and (ii) in a transaction subject to treatment under Section 707(a) of the Code, and its implementing Treasury Regulations, as in part a sale, and in part a contribution, by Contributor of the assets of the Company (and the assets of the Subsidiaries of the Company) to the extent Section 1.707-4(d) of the Treasury Regulations is inapplicable. The Parties agree to file all Tax Returns and otherwise act at all times in a manner consistent with this intended treatment of the contribution of the Contributed Interests, the Cash Consideration, and the Regency Debt, including disclosing the distribution of the Cash Consideration in accordance with the requirements of Section 1.707-3(c)(2) of the Treasury Regulations; provided that, notwithstanding the foregoing, Regency shall not be required to take any position in any taxable year to the extent Regency determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances. Contributor shall reimburse Regency and its Affiliates for all of their costs and expenses (including legal fees) relating to a new credit facility (but not for a debt offering) as contemplated by this Section 2.8. Contributor agrees that it shall be solely liable for any Taxes attributable to the receipt by Contributor of the Cash Consideration and the Acquired Units.

4.20 Matters Relating to Acquisition of the Contributed Interests.

(a) Regency has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of its investment in the Contributed Interests and is capable of bearing the economic risk of such investment. Regency is an “accredited investor” as that term is defined in Rule 501 of Regulation D (without regard to Rule 501(a)(4)) promulgated under the Securities Act. The Regency Parties are acquiring the Contributed Interests for investment for their own account and not with a view toward or for sale in connection with any distribution thereof, or with any present intention of distributing or selling the Contributed Interests. Neither of the Regency Parties has any Contract or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to the Contributed Interests. The Regency Parties acknowledge and understand that (i) the acquisition of the Contributed Interests has not been registered under the Securities Act in reliance on an exemption therefrom and (ii) the Contributed Interests will, upon such acquisition, be characterized as “restricted securities” under state and federal securities laws. The Regency Parties agree that the Contributed Interests may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of except (A) in accordance with the requirements of the SUGC Company Agreement or (B) pursuant to an effective registration statement under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with other applicable state and federal securities laws.

(b) The Regency Parties have undertaken such investigation as they have deemed necessary to enable them to make an informed and intelligent decision with respect to the execution, delivery and performance of this Agreement and the acquisition of the Contributed Interests. The Regency Parties have had an opportunity to ask questions and receive answers from the Contributor regarding the terms and conditions of the offering of the Contributed Interests and the business, properties, prospects, and financial condition of the Company (to the extent the Contributor possessed such information). The foregoing, however, does not modify the representations and warranties of the Contributor in Article III and such representations and warranties constitute the sole and exclusive representations and warranties of the Contributor to the Regency Parties in connection with the transactions contemplated by this Agreement.

The Contributor and Regency shall use commercially reasonable best efforts to cause their respective Audit Firm to consent to the inclusion or incorporation by reference of its audit opinion with respect to any of the financial statements of the Acquired Companies and Regency Parties in any such registration statement, report or other filing of the Contributor, Regency or any of their respective Affiliates, and the

Contributor and Regency shall cause representation letters, in form and substance reasonably satisfactory to their respective Audit Firm, to be executed and delivered to their respective Audit Firm in connection with obtaining any such consents from their respective Audit Firms.

(c) The Contributor and Regency shall cooperate with the other party in connection with the preparation of any pro forma financial statements of the Contributor, Regency or any of their respective Affiliates that are derived in part from the financial statements of the Contributor or Regency that the Contributor, Regency or their respective Affiliates reasonably determines are required to be included or incorporated by reference in any registration statement, report or other filing of the Contributor, Regency or any of their respective Affiliates to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act.

(d) Each of the Contributor and Regency shall provide access to its Books and Records as may be reasonably necessary for the Contributor, Regency or any of their respective Affiliates, or any of their respective advisors or Representatives, to conduct customary due diligence with respect to the financial statements of the Contributor and Regency in connection with any offering of securities by the Contributor, Regency or any of their respective Affiliates, or to enable an accounting firm to prepare and deliver a customary comfort letter with respect to financial information relating to the Contributor or Regency.

(e) Except as described on Schedule 5.13(e) of the Contributor Disclosure Schedule, on or prior to the Closing Date, the Contributor shall cause (i) all intercompany agreements and arrangements (including all cost-sharing and service agreements, loans, debentures, letters of credit and guarantees) between the Contributor and/or its Affiliates (provided that for purposes of this Section 5.13(e) the Acquired Companies shall not constitute Affiliates of the Contributor), on the one hand, and the Acquired Companies, on the other hand, to be terminated; and (ii) all intercompany accounts and liabilities (including any open balances), between the Contributor and/or its Affiliates, on the one hand, and the Acquired Companies, on the other hand, payable under such intercompany agreements and arrangements to be terminated pursuant to this Section 5.13(e).

5.14 Updating Schedules. Prior to the Closing Date, the Contributor and the Regency Parties shall have the right from time to time to supplement or amend the Contributor Disclosure Schedule and the Regency Disclosure Schedule, respectively, including by the addition of new schedules with respect to any representations and warranties of the Contributor or the Regency Parties in this Agreement for which no schedule was provided as of the date hereof, with respect to any matter arising or discovered after the date of this Agreement which matter, if existing or known as of the date hereof, would have been set forth in such Party’s Disclosure Schedule; provided that for purposes of Section 6.2(a) and 6.3(a), any such supplement or amendment to the Contributor Disclosure Schedule or the Regency Disclosure Schedule shall not be deemed to have been disclosed in the Contributor Disclosure Schedule or the Regency Disclosure Schedule unless agreed to in writing by the other Party. For purposes of the rights and obligations of the parties hereunder, upon the occurrence of the Closing, any amendments or supplements to the Contributor Disclosure Schedule or the Regency Disclosure Schedule shall become part of the Contributor Disclosure Schedule or the Regency Disclosure Schedule, as applicable, and part of this Agreement.

5.15 Risk of Loss. If any loss, damage, impairment, confiscation or condemnation of any of the assets or properties of the Acquired Companies from any cause whatsoever occurs on or prior to Closing, the Contributor shall apply the proceeds of any insurance policy, judgment or award with respect thereto to repair, replace or restore the assets or properties of the Acquired Companies as soon as possible (whether before, on or after Closing) to their prior condition. In the event (“Material Casualty Event”) of any damage or destruction to the assets or properties of the Acquired Companies that would result in the nonsatisfaction of a condition precedent to the Regency Parties’ obligation to consummate this Agreement, the Regency Parties, at their option, may either terminate this Agreement or proceed to close this Agreement on the Closing Date, in which event the Contributor shall pay or assign to the Regency Parties (together with the amount of any deductible or self-insured retention) the proceeds from any insurance policies covering the assets or properties subject to the Material Casualty Event to the extent such proceeds are received by or payable to the Contributor and have not been used in or committed to the restoration or replacement of the assets or properties subject to the Material Casualty Event as of the Closing Date. This Section 5.15 will provide the exclusive remedy for each of the Parties for any and all claims relating (directly or indirectly) to any Material Casualty Event.

5.16 Non-Compete

(a) During the three (3) year period following the Closing Date, Contributor shall not, and shall cause the Contributor’s Affiliates not to, directly or indirectly, in any of the geographic areas identified on Schedule 5.16 (each, a “Restricted Area”): (i) acquire, own any interest in, control, or operate a natural gas gathering, treating, processing, compression or storage system (a “Competing Business”) or (ii) for the purpose of conducting or engaging in a Competing Business, call upon, solicit, advise or otherwise do, or attempt to do, business with any clients, suppliers, customers or accounts relating to the business of the Acquired Companies. The preceding sentence shall not apply in the case of Contributor’s or any of Contributor’s Affiliate’s acquisition, directly or indirectly, of an entity or a business (the “Acquisition Target”) that includes a Competing Business in the event that (A) Contributor or Contributor’s Affiliate makes an Offer (as defined herein) and complies fully with the provisions of Section 5.16(b) or (B) Contributor makes a good faith determination that the portion of such Acquisition Target constituting the Competing Business is not commercially reasonably separable from the Acquisition Target, taken as a whole, and the Competing Business constitutes less than 15% of the Acquisition Target’s assets or operations;

(b) (i) If Contributor or any of Contributor’s Affiliates acquires an Acquisition Target that includes a Competing Business subject to the noncompetition provisions of Section 5.16(a), then not later than six (6) months after the consummation of the acquisition by Contributor or any of Contributor’s Affiliates of the Acquisition Target that includes such Competing Business, Contributor shall notify Regency in writing of such acquisition and offer Regency the opportunity to purchase such Competing Business in accordance with this Section 5.16(b) (the “Offer”). The Offer shall set forth preliminary terms relating to the sale and purchase of the Competing Business. As soon as practicable, but in any event within sixty (60) days after receipt of the Offer, Regency shall notify Contributor in writing that either (A) Regency has elected, with the approval of the Regency Conflicts Committee, not to purchase the Competing Business, in which event Contributor or Contributor’s Affiliates, as applicable, shall be forever free to continue to own or operate such Competing Business, or (B) Regency has elected to

negotiate the purchase of the Competing Business, in which event the procedures outlined in this Section 5.16(b)(ii) and (iii) shall apply. In the event that Regency fails to deliver a written notice pursuant to Section 5.16(b)(i)(A) or (B) within sixty days after receipt of the Offer or after giving such written notice fails to consummate the purchase of the Competing Business, Regency shall be deemed to have elected not to purchase the Competing Business with the approval of the Regency Conflicts Committee, and Contributor or Contributor’s Affiliates, as applicable, shall be forever free to continue to own or operate such Competing Business.

(ii) If Contributor or Contributor’s Affiliates, as applicable, and Regency (with the concurrence of the Regency Conflicts Committee) are able to agree on the fair market value of the Competing Business that is subject to the Offer and the other terms of a definitive agreement within sixty (60) days after Contributor’s receipt of Regency’s election to negotiate the purchase of the Competing Business, Regency shall purchase the Competing Business for the agreed upon fair market value and other terms as soon as commercially practicable after such definitive agreement has been reached.

(iii) If Contributor or Contributor’s Affiliates, as applicable, and Regency are unable to agree on the fair market value of the Competing Business or the other terms of a definitive agreement within sixty (60) days after Contributor’s receipt of Regency’s election to negotiate the purchase of the Competing Business, Contributor and Regency will engage a mutually agreed upon, nationally recognized investment banking firm to determine the fair market value of the Competing Business and/or the other terms on which Contributor and Regency are unable to agree. Such investment banking firm will determine the fair market value of the Competing Business and/or the other terms on which Contributor and Regency are unable to agree within thirty (30) days of its engagement and furnish Contributor and Regency its determination. Once the investment banking firm has submitted its determination of the fair market value of the Competing Business and/or the other terms on which Contributor and Regency are unable to agree, Regency will have the right, but not the obligation, subject to the approval of the Regency Conflicts Committee, to purchase the Competing Business that is subject to the Offer on the agreed-upon terms and as otherwise determined by the investment banking firm. If Regency elects to purchase the Competing Business, then it shall purchase, and Contributor shall sell (or cause Contributor’s Affiliates to sell, if applicable) the Competing Business on the agreed-upon terms and as otherwise determined by the investment banking firm as soon as commercially practicable after such determination and the fees of the investment banking firm will be split equally between Contributor and Regency. If Regency fails to elect to purchase the Competing Business within fifteen (15) days of the receipt of such terms from the investment banking firm, (i) Regency will be deemed to have elected, with the approval of the Regency Conflicts Committee, not to purchase the Competing business, (ii) the fees of the investment banking firm will be paid solely by Regency and (iii) Contributor or Contributor’s Affiliates, as applicable, shall be forever free to continue to own or operate such Competing Business.

(c) In the event that the covenants in this Section 5.16 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great of time or over too great a geographical area or by reason of its being too extensive in any other respect, they shall be interpreted to extend only over the maximum period of time for which they may be enforceable and/or over the maximum geographical area as to which they may be enforceable and/or to the maximum extent in all other respects as to which they may be enforceable, all as determined by such court in such action.

(d) Contributor acknowledges that a breach of the covenants contained in this Section 5.16 will cause irreparable damage to the Regency Parties, the Company, their Subsidiaries or their businesses, the exact amount which will be difficult to ascertain, and that remedies at law for any such breach will be inadequate. Accordingly, Contributor agrees that if it, its Subsidiaries or Affiliates breach any of the covenants contained in this Section 5.16, in addition to any other remedy which may be available at law or in equity, Regency shall be entitled to specific performance and injunctive relief, without posting a bond or any other security.

(e) Each of ETE, ETP and Holdco severally agrees (and agrees to cause its respective Affiliates) to comply with the terms and conditions of this Section 5.16. Each of ETE and ETP is executing this Agreement for the sole purposes of agreeing to this Section 5.16 and Section 5.20. Holdco is executing this Agreement for the sole purposes of agreeing to this Section 5.16 and Section 5.9.

5.17 Hedges. Contributor shall terminate on or prior to Closing any hedges, swaps, collars or any other derivative contracts that hedge against the price of any commodity or interest rate with respect to the Acquired Companies.

5.18 Employee Matters.

(a) Following the date hereof and prior to the Closing Date, Regency shall, or shall cause the Acquired Companies or another Affiliate of Regency to offer to employ as a direct employee of Regency, the Acquired Companies or another Affiliate of Regency each employee of Contributor (i) who is assigned to, and devotes substantially all of his or her time to, providing services to the Acquired Companies, each of whom shall be identified by Contributor in a list to be provided to Regency within thirty (30) days after the Execution Date (collectively, the “Dedicated Employees”), which list shall include the name, title, business location and annual compensation of each Dedicated Employee, (ii) who devotes some, but less than substantially all, of his or her time to providing services to the Acquired Companies, each of whom Contributor and Regency shall identify by mutual agreement prior to the Closing Date (collectively, the “Shared Employees”), and (iii) who, without regard to whether he or she is a Dedicated Employee or a Shared Employee, is listed in Schedule 5.18(a)(iii) of the Contributor Disclosure Schedule (collectively, the “Listed Employees”, and together with the Dedicated Employees and Shared Employees, the “Offered Employees”). Such offers shall be for employment with substantially the same title and position, and with (i) a base pay or salary rate at least equal to the base pay or salary rate as in effect with respect to each such Offered Employee immediately prior to the Closing Date and (ii) bonus opportunities and employee benefits no less favorable in the aggregate than the bonus opportunities and employee benefits offered or provided to similarly situated employees of Regency and its Affiliates. Both the offers from Regency or its Affiliates and any acceptances thereof by the Offered Employees shall be contingent upon the consummation of the transaction contemplated in this Agreement and effective upon the Closing Date. Offered Employees who accept such offers of employment from Regency or its Affiliates are referred to herein as “Transferred Employees.” Such employment of Transferred Employees as direct employees of Regency, the Acquired Companies or another Affiliate of Regency (as applicable) shall commence effective as of the Closing Date.

(b) For a period of at least 12 months following the Closing Date, Regency shall, or shall cause the Acquired Companies or another Affiliate of Regency to, provide each Transferred Employee with (i) a base pay or salary rate at least equal to the base pay or salary rate as in effect with respect to such Transferred Employee immediately prior to the Closing Date and (ii) bonus opportunities and employee benefits no less favorable in the aggregate than the bonus opportunities and employee benefits offered or provided to similarly situated employees of Regency and its Affiliates. The Transferred Employees shall receive credit for all periods of employment and/or service with Contributor and its Affiliates prior to the Closing Date for purposes of eligibility, vesting and benefit accrual under all plans, programs and arrangements made available to such Transferred Employees, except for purposes of benefit accruals under defined benefit pension plans unless required by Applicable Law. For the calendar year in which the Closing Date occurs, each Transferred Employee will accrue an amount of vacation time equal to that which a similarly situated employee of Regency and its Affiliates (with tenure that includes all of such Transferred Employee’s periods of employment and/or service with Contributor and its Affiliates prior to the Closing Date) would accrue under the policies of Regency and its Affiliates.

(c) Regency shall be responsible for all continuation coverage under Section 601 et seq. of ERISA (“COBRA Obligations”) and any state continuation coverage requirements accrued after the Closing Date with respect to the Transferred Employees and their beneficiaries, provided such Transferred Employees enroll in a group health plan sponsored by Regency or one of its Affiliates. Contributor agrees that it shall retain responsibility for COBRA Obligations to all employees and their beneficiaries who are not Transferred Employees for whom a “qualifying event” under COBRA occurs or has occurred.

(d) Regency shall not assume or otherwise be responsible for any liability, claim, loss, severance, bonus or benefit accrued or owed under any Company Benefit Plan or otherwise with respect to any employee that (1) does not become a Transferred Employee, irrespective of the date of accrual of such liability, or (2) becomes a Transferred Employee, only to the extent such liability, claim, loss, severance, bonus or benefit has accrued on or prior to the Closing Date. Contributor and not Regency shall be responsible for any severance payments that become due under any Company Benefit Plan of Contributor or its Affiliates to an employee whose employment with Contributor or its Affiliates is terminated in conjunction with the transaction contemplated in this Agreement either because (1) the employee is not an Offered Employee and, as such, does not receive an offer of employment from Regency the Acquired Companies or another Affiliate of Regency or (2) the Offered Employee receives an offer of employment from Regency, the Acquired Companies or another Affiliate of Regency, but elects not to accept such offer.

(e) In the event that any Transferred Employee is required to forfeit equity in Contributor or one of Contributor’s Affiliates in order to accept an offer of employment from Regency, Regency shall use commercially reasonable best efforts to ensure that such Transferred Employee(s), receives equity in Regency or one of its Affiliates of substantially equal value.

(f) Nothing herein express or implied by this Agreement shall (i) confer upon any employee, including but not limited to any Offered Employee or Transferred Employee, or legal representative thereof, any rights or remedies, including any right to employment or benefits for any specified period, of any nature or kind whatsoever, under or by reason of this Agreement, or (ii) be deemed to amend any employee benefit plan of Contributor, Regency or any of their Affiliates.

5.19 Use of the Company’s Names and Marks.

(a) With respect to the phase-out of the use of the Company’s Names and Marks, the Regency Parties agree as follows: (i) as soon as practicable following the Closing, but in no event later than ten Business Days after Closing, Regency shall, and after the Closing shall cause the Acquired Companies to, change the names of the Acquired Companies to a name that does not include any of Company’s Names and Marks or comprise any colorable imitations thereof; and (ii) as soon as practicable following the Closing, but in no event later than 90 days after Closing, Regency shall, and after the Closing shall cause the Acquired Companies to, cease and permanently discontinue any and all uses of any of the Company’s Names and Marks and any colorable imitations thereof, and remove or cover all of the Company’s Names and Marks from or on, or destroy, any publications, signage, corporate letterhead, invoices, stationery, business cards, marketing materials, website content or other materials in the Company’s possession or under its control bearing any of the Company’s Names and Marks (other than any existing correspondence, files, contracts and other similar instruments and any Books and Records that bear the Company’s Names or Marks), and provide Contributor with written confirmation thereof. Notwithstanding the foregoing, Regency shall have a period of up to twelve (12) months from the Closing to cause the Acquired Companies to permanently remove the Company’s Names and Marks from pipeline markers on the assets of the Acquired Companies.

(b) In no event shall Regency or any of its Affiliates (including, after Closing, the Acquired Companies) use any of the Company’s Names and Marks after Closing in any manner or for any purpose different from the use of such of the Company’s Names and Marks by the Acquired Companies preceding the Closing, and none of them shall affix or include any of the Company’s Names and Marks, or any colorable imitations thereof, on any publications, signage, corporate letterhead, invoices, stationery, business cards, marketing materials, website content or other materials that are created or produced after the Closing.

(c) Regency expressly acknowledges and confirms that Contributor is not transferring or assigning, and Regency shall not receive, any right, title or interest in or to the Company’s Names and Marks, except the limited right to use for the sole purpose of permitting Regency to complete the phase-out in strict compliance with this Section 5.19. Furthermore, all use of the Company’s Names and Marks hereunder during the phase-out period shall be at all times subject to Contributor’s direction and control and any and all use thereof by Regency or the Acquired Companies hereunder shall inure to the exclusive benefit of Contributor, and Buyer shall, and after the Closing shall cause the Acquired Companies to, comply with Contributor’s instructions and direction at all times.

5.20 Shared Services. The Parties will cooperate in good faith to negotiate, on mutually agreed upon terms, definitive documentation regarding items listed on Exhibit F.

5.21 Release from Credit Support Instruments. Regency shall use commercially reasonable best efforts to, and shall cause its Affiliates to use commercially reasonable best efforts to, secure the unconditional release, as of the Closing Date, of Contributor and its Affiliates from the credit support instruments set forth in Schedule 5.21 to the extent, but only to the extent, that such instruments provide credit support to any of the Acquired Companies (the “Acquired Companies Credit Support”), including effecting such release by providing guarantees or other credit support for obligations of the Acquired Companies, and Regency shall use commercially reasonable best efforts to, and shall cause its Affiliates to use commercially reasonable best efforts to, be substituted in all respects for Contributor and each of its Affiliates that provide the Acquired Companies Credit Support, so that Regency shall be solely responsible for the obligations of such Acquired Companies Credit Support. Contributor shall use its commercially reasonable best efforts to assist Regency in its efforts to secure the release of the Acquired Companies Credit Support; provided that Regency’s failure to effect any such release by providing guarantees or other credit support for obligations of the Acquired Companies shall relieve Contributor from its duty to assist Regency in such efforts with respect to any such release. To the extent Regency is unable to obtain release for any Acquired Companies Credit Support as of the Closing, Regency shall indemnify Contributor and its Affiliates for any and all Losses arising from or relating to the Acquired Companies Credit Support Instruments arising after the Closing Date. In the event that any Acquired Companies Credit Support has not been terminated and Contributor or any of its Affiliates has not been released as of the Closing Date, Contributor and/or such Affiliate shall be permitted to terminate such Acquired Companies Credit Support as promptly as possible under the terms of each applicable credit support instrument.

5.22 Delivery of Audited 2012 Financial Statements. Contributor shall deliver to Regency as soon as reasonably practicable but no later than March 31, 2013 true and complete copies of audited consolidated balance sheets of the Acquired Companies as of December 31, 2012 and the related audited statements of operations, changes in parent equity and cash flows for the year ended December 31, 2012 (collectively, the “Audited 2012 Financial Statements”). Between the Execution Date and the Closing Date, Contributor shall deliver to Regency as soon as reasonably practicable after the end of each fiscal quarter (but no later than forty (40) days after the end of each fiscal quarter) of the Acquired Companies unaudited consolidated balance sheets of the Acquired Companies as of the end of each such quarter and the related unaudited statements of operations, changes in parent equity and cash flows for the period then ended, in each case with SAS 100 reviews by the appropriate Audit Firm.

No later than five (5) days prior to the end of each calendar quarter between the Execution Date and the Closing Date, Contributor shall deliver to the Regency Parties a detailed capital expenditure budget for the following calendar quarter in a form substantially similar to the information with respect to the first calendar quarter of 2013 that is contained in Schedule 3.11(c) of the Contributor Disclosure Schedules.

(d) Survival; Claims Period.

(i) The representations, warranties, covenants and agreements of the Parties under this Agreement shall survive the execution and delivery of this Agreement and

shall continue in full force and effect until the two-year anniversary of the Closing Date (the “Expiration Date”); provided that (A) the Fundamental Representations (other than the representations and warranties set forth in Section 3.16 and Section 4.15 shall survive indefinitely, (B) the representations and warranties set forth in Section 3.16 (Taxes), Section 3.17 (Employee Benefits; Employment and Labor Matters), Section 4.15 (Taxes) and Section 4.16 (Employee Benefits; Employment and Labor Matters) shall survive the execution and delivery of this Agreement and shall continue in full force and effect until ninety (90) days after the expiration of the applicable statute of limitations, including any extensions thereof (which shall be deemed to be the Expiration Date with respect to such representations and warranties) and (C) any covenants or agreements contained in this Agreement that by their terms are to be performed after the Closing Date shall survive until fully discharged.

(iii) For purposes of this Article VIII, all qualifications of the representations and warranties contained in Article III and Article IV by materiality (whether by reference to the terms “material,” “Company Material Adverse Effect,” “Regency Material Adverse Effect”), other than those contained in Section 3.10(b) and Section 4.9(c), shall be disregarded.

(e) Calculation of Losses.

(i) In calculating amounts payable to any Contributor Indemnitee or Regency Indemnitee (each such person, an “Indemnified Party”) for a claim for indemnification hereunder, the amount of any indemnified Losses shall be determined without duplication of any other Loss for which an indemnification claim has been made or could be made under any other representation, warranty, covenant or agreement and shall be computed net of (A) payments actually recovered by the Indemnified Party under any insurance policy with respect to such Losses or from any other Person alleged to be responsible therefore and (B) any prior or subsequent actual recovery by the Indemnified Party from any Person with respect to such Losses.

(ii) The Indemnified Party must use commercially reasonable best efforts to mitigate in accordance with applicable Law any Loss for which the Indemnified Party seeks indemnification under this Agreement, including cooperating with the Indemnifying Party to take all commercially reasonable measures to mitigate the consequences of the related breach.

(iii) Contributor shall have no obligation to indemnify the Regency Parties or their Affiliates pursuant to Section 8.1 to the extent Losses result or arise from environmental invasive testing of soil, water or any other parts of the environment that

can contain contaminants with respect to any assets of the Acquired Companies (“Environmental Test”), unless (A) such Environmental Test is (w) required by Environmental Laws, (x) requested by a Governmental Authority with authority under Environmental Laws, (y) requested by a prospective or direct or indirect purchaser of, or third party providing financing for, Regency or any of its Affiliates, or any of the Acquired Companies or (z) necessary in connection with a bona fide expansion, reconfiguration, maintenance, dismantling, or repair of the assets of any of the Acquired Companies, or (B) there exists visual (or other sensory) or physical evidence that is manifest and would cause a reasonably prudent Person to suspect that there exists pollution or contamination in the soil or groundwater.

(iv) The Contributor shall have no obligation to indemnify the Regency Parties or their Affiliates pursuant to Section 8.1 with respect to any Losses or alleged Losses to the extent that such Losses or alleged Losses were taken into account in the determination of Closing Date Net Working Capital.

(v) Except as required by applicable Law following a final determination within the meaning of Section 1313 of the Code, any indemnity payment under this Agreement shall be treated as an adjustment to the Final Contribution Consideration for Tax purposes.

(f) Waiver of Certain Damages. Notwithstanding any other provision of this Agreement, in no event shall any Party be liable for punitive, damages or any multiples of earnings damages of any kind or nature, regardless of the form of action through which such damages are sought, except for any such damages recovered by any third party against an Indemnified Party in respect of which such Indemnified Party would otherwise be entitled to indemnification pursuant to the terms hereof.

(g) Sole and Exclusive Remedy.

(i) After the Closing, Article VIII will provide the exclusive remedy for each of the Parties for any and all claims relating (directly or indirectly) to this Agreement and the transactions contemplated hereby, including any misrepresentation, breach of representation, warranty, covenant or other agreement or other claim arising out of this Agreement or the transactions contemplated hereby (other than the post-Closing reconciliations pursuant to Section 2.5 and Section 2.6 and other than equitable remedies as they relate to breaches of covenants or other agreements contained herein to the extent such covenants or agreements are to be performed after the Closing), regardless of applicable Law or the legal theory under which such liability or obligation may be sought or imposed, whether sounding in contract or tort, or whether at law or in equity or otherwise. Notwithstanding the foregoing, nothing herein shall preclude any Party from asserting a claim of Fraud or willful misconduct.

(ii) Except as specifically set forth in this Agreement, effective as of the Closing, Regency waives any rights Regency or its Affiliates may have against the Contributor, whether at law or in equity, relating to claims for contribution and other rights of recovery arising out of or relating to any Environmental Law (whether now or hereinafter in effect).

8.4 Indemnification Procedures.

(a) Each Indemnitee agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant to this Article VIII, such Indemnitee must assert its claim for indemnification under this Article VIII (each, a “Claim”) by providing a written notice (a “Claim Notice”) to the Indemnifying Party allegedly required to provide indemnification protection under this Article VIII specifying, in reasonable detail, the nature and basis for such Claim (e.g., the underlying representation, warranty, covenant or agreement alleged to have been breached). Notwithstanding the foregoing, an Indemnitee’s failure to send or delay in sending a third party Claim Notice will not relieve the Indemnifying Party from liability hereunder with respect to such Claim except to the extent the Indemnifying Party is actually prejudiced by such failure or delay and except as is otherwise provided herein, including in Section 8.3(e).

(b) In the event of the assertion of any third party Claim for which, by the terms hereof, an Indemnifying Party is obligated to indemnify an Indemnitee, the Indemnifying Party will have the right, at such Indemnifying Party’s expense, to assume the defense of same including the appointment and selection of counsel on behalf of the Indemnitee so long as such counsel is reasonably acceptable to the Indemnitee. If the Indemnifying Party elects to assume the defense of any such third party Claim, it shall, within 30 days of its receipt of the Claim Notice, notify the Indemnitee in writing of its intent to do so. The Indemnifying Party will have the right to settle or compromise or take any corrective or remediation action with respect to any such Claim by all appropriate Proceedings, which Proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party. The Indemnitee will be entitled, at its own cost, to participate with the Indemnifying Party in the defense of any such Claim. If the Indemnifying Party assumes the defense of any such third-party Claim but fails to diligently prosecute such Claim, or if the Indemnifying Party does not assume the defense of any such Claim, the Indemnitee may assume control of such defense and if it is determined pursuant to the procedures set forth in Article IX that the Claim was a matter for which the Indemnifying Party is required to provide indemnification under the terms of this Article VIII, the Indemnifying Party will bear the reasonable costs and expenses of such defense (including reasonable attorneys’ fees and expenses). Notwithstanding the foregoing, the Indemnifying Party may not assume the defense of the third-party Claim (but will be entitled at its own cost to participate with the Indemnified Party in the defense of any such Claim) if the potential Losses under the third-party Claim could reasonably and in good faith be expected to exceed, in the aggregate when combined with all claims previously made by the Indemnified Party to the Indemnifying Party under this Article VIII, the maximum amount for which the Indemnifying Party may be liable pursuant to Section 8.3(c); provided, however, that to the extent the Parties are not in agreement with respect to the calculation of potential Losses, the Indemnifying Party shall have the right to assume the defense of the third-party Claim in accordance herewith until the Parties have agreed or a final non-appealable judgment has been entered into, with respect to the determination of the potential Losses.

(c) Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter

into an agreed judgment or consent decree that: (i) subjects the Indemnitee to any criminal liability, (ii) requires an admission of guilt, wrongdoing or fault on the part of the Indemnitee, (iii) imposes any continuing obligation on the Indemnitee, (iv) does not include an unconditional release of the Indemnitee, or (v) requires any payment from the Indemnitee, in each case without the Indemnitee’s prior written consent.

REGISTRATION RIGHTS

Section 2.01 Shelf Registration.

(a) Shelf Registration. At the option and upon the request of the holders of a majority of the Common Units covered by this Agreement, Regency shall prepare and file a registration statement under the Securities Act to permit the public resale of the Registrable Securities from time to time as permitted by Rule 415 (or any similar provision then in force) of the Securities Act (the “Shelf Registration Statement”). Regency shall use its reasonable best efforts to file the Shelf Registration Statement within 45 days of any such request and cause it to be effective as soon as reasonably practicable thereafter (the “Shelf Registration”); provided, however, that Regency shall not be required to effect more than three registrations pursuant to this Section 2.01(a). The Shelf Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be selected by Regency; provided, however, that if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from the Shelf Registration Statement and the Managing Underwriter at any time shall notify Southern Union in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, Regency shall use its reasonable best efforts to include such information in such a prospectus supplement. Regency will cause the Shelf Registration Statement filed pursuant to this Section 2.01(a) to be continuously effective under the

-2-

Securities Act until all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in the Shelf Registration Statement or there are no longer any Registrable Securities outstanding (the “Effectiveness Period”). The Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. If Regency determines in good faith that the requested registration would be materially detrimental to Regency because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving Regency, (y) require premature disclosure of material information that Regency has a bona fide business purpose for preserving as confidential or (z) render Regency unable to comply with requirements under applicable securities laws, then Regency shall have the right to postpone such requested registration for a period of not more than three months after receipt of Southern Union’s request, such right pursuant to this Section 2.01(b) not to be utilized more than twice in any twelve-month period.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, Regency may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if Regency (i) is pursuing a financing, acquisition, merger, reorganization, disposition or other similar transaction and determines in good faith that its ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Regency would materially adversely affect Regency. Upon disclosure of such information or the termination of the condition described above, Regency shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.02 Underwritten Offering. In the event that the Selling Holders holding a majority of the Common Units covered by this Agreement elect to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering, Regency shall enter into an underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.07, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the registration and disposition of the Registrable Securities. In connection with any Underwritten Offering under this Agreement, Regency shall be entitled to select the Managing Underwriter or Underwriters, subject to the consent of Southern Union not to be unreasonably withheld or delayed. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Regency to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Regency other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representations required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to Regency and the Managing Underwriter; provided, however, that such notice of withdrawal must be made before or at the time of pricing of such offering in order to be effective. No such withdrawal or abandonment shall affect Regency’s obligation to pay Registration Expenses.

(a) prepare and file with the Commission such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement;

(b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Shelf Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including furnishing or making available exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Shelf Registration Statement or supplement or amendment thereto, and (ii) such number of copies of the Shelf Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement;

(c) if applicable, use its reasonable best efforts to register or qualify the Registrable Securities covered by the Shelf Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request, provided that neither Regency nor its general partner will be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d) promptly notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of the Shelf Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Shelf Registration Statement, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Shelf Registration Statement or any prospectus or prospectus supplement thereto;

(e) immediately notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Shelf Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Regency of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Regency agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances then existing, and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(i) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Regency personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that Regency need not disclose any information to any such representative unless and until such representative has entered into a confidentiality agreement with Regency;

(j) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Regency are then listed;

(k) use its reasonable best efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Regency to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(l) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement; and

Section 2.04 Cooperation by Holders. Regency shall have no obligation to include in the Shelf Registration Statement units of a Holder who has failed to timely furnish such information which, in the opinion of counsel to Regency, is reasonably required in order for the Shelf Registration Statement or any prospectus or prospectus supplement thereto, as applicable, to comply with the Securities Act.

-5-

Section 2.05 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the lock-up period contained in a prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, provided that (i) Regency gives written notice to such Holder of the date of the commencement and termination of such period with respect to any such Underwritten Offering and (ii) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on Regency or on the officers or directors or any other unitholder of Regency on whom a restriction is imposed.

Section 2.06 Expenses.

(a) Certain Definitions. “Registration Expenses” means all expenses incident to Regency’s performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for Regency, including the expenses of any special audits or “comfort letters” required by or incident to such performance and compliance. Except as otherwise provided in Section 2.07 hereof, Regency shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, Regency shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions allocable to the sale of the Registrable Securities.

(b) Expenses. Regency will pay all Registration Expenses in connection with any Shelf Registration Statement filed pursuant to Section 2.01(a) of this Agreement, whether or not the Shelf Registration Statement becomes effective or any sale is made pursuant to the Shelf Registration Statement. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.07 Indemnification.

(a) By Regency. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Regency will indemnify and hold harmless each Selling Holder thereunder, its directors and officers and each underwriter pursuant to the applicable underwriting agreement with such underwriter and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or underwriter or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors and officers, each such underwriter and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Regency will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, such underwriter or such controlling Person in writing specifically for use in the Shelf Registration Statement or any prospectus contained therein or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

-6-

(b) By Each Selling Holder. Each Selling Holder agrees severally and jointly to indemnify and hold harmless Regency, its directors and officers, and each Person, if any, who controls Regency within the meaning of the Securities Act or of the Exchange Act against any Losses to the same extent as the foregoing indemnity from Regency to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or any prospectus contained therein or any amendment or supplement thereof relating to the Registrable Securities; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but such indemnified party’s failure to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to any indemnified party other than under this Section 2.07. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.07 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of one such separate counsel (firm) and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 2.07 is held by a court or government agency of competent jurisdiction to be unavailable to Regency or any Selling Holder or is insufficient to hold it harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses as between Regency, on the one hand, and such Selling Holder, on the other hand, in such proportion as is appropriate to reflect the relative fault of Regency, on the one hand, and of such Selling Holder, on the other, in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of Regency, on the one hand, and each Selling Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with

-7-

investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.07 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.08 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Regency agrees to use its reasonable best efforts to:

(a) Make and keep public information regarding Regency available, as those terms are understood and defined in Rule 144 of the Securities Act, at all times from and after the date hereof;

(b) File with the Commission in a timely manner all reports and other documents required of Regency under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Regency, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.09 Transfer or Assignment of Registration Rights. The rights to cause Regency to include Registrable Securities in a Shelf Registration Statement may be transferred or assigned by Southern Union to one or more transferee(s) or assignee(s) of such Registrable Securities, provided that (a) such transferee or assignee is an Affiliate of Southern Union or receives at least 20% of the Common Units covered by this Agreement, (b) Regency is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of Southern Union under this Agreement.

Section 2.10 Information by Holder. Any Holder or Holders of Registrable Securities included in any registration statement shall promptly furnish to Regency such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as Regency may reasonably request and as shall be required in connection with any registration, qualification or compliance referred to herein.

Section 3.02 Books and Records; Financial Information.

(a) Regency shall provide to Southern Union and its Affiliates access upon reasonable notice during normal business hours to the Regency’s books and records to the extent reasonably necessary to prepare financial statements of Southern Union and its Affiliates in such forms and covering such periods as may be required by any applicable securities laws to be filed with the SEC by Southern Union or any of its Affiliates as a result of the transactions contemplated by this Agreement. Regency shall use its reasonable best efforts to cause its independent accountants to provide any consent necessary to the filing of such financial statements with the SEC and to provide such customary representation letters as are necessary in connection therewith. Until such time none of Southern Union and any of its Affiliates shall be obligated to include financial information with respect to Regency in any of their reports required to be filed with the SEC, Regency’s obligations under this Section 3.02 shall include the obligation to provide to Southern Union or any of its Affiliates, at Southern Union or such Affiliate’s expense, the accounting and financial information set forth on Schedule I.

(b) Regency hereby consents to the inclusion or incorporation by reference of the financial statements of the Regency in any registration statement, report or other filing of Southern Union or any of its Affiliates as to which Southern Union or any of its Affiliates reasonably determines that such financial statements are required to be included or incorporated by reference to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act. Regency shall use reasonable best efforts to cause its independent auditors to consent to the inclusion or incorporation by reference of its audit opinion with respect to any of the financial statements of Regency in any such registration statement, report or other filing of Southern Union or any of its Affiliates, and Regency shall cause representation letters, in form and substance reasonably satisfactory to the its independent auditors, to be executed and delivered to the independent auditors in connection with obtaining any such consent.

-9-

(c) Regency shall provide access upon reasonable notice during normal business hours to its books and records as may be reasonably necessary for Southern Union or any of its Affiliates, or any of its advisors or representatives, to conduct customary due diligence with respect to the financial statements of Regency in connection with any offering of securities by Southern Union or any of its Affiliates or to enable an accounting firm to prepare and deliver a customary comfort letter with respect to financial information relating to Regency. Southern Union or its Affiliates shall reimburse Regency for any cost or expenses incurred by Regency in connection with the foregoing.

(d) Southern Union and its Affiliates shall not, directly or indirectly, disclose to any Person any confidential Information provided to Southern Union pursuant to this Section 3.02 (“Information”), which has not become generally available to the public, other than as a result of a breach of this Agreement. Notwithstanding the foregoing, (A) in the event that Southern Union or any of its Affiliates is required by Law or applicable stock exchange rules to disclose any Information, such party shall (1) notify Regency as promptly as practicable of the existence, terms and circumstances surrounding such a request, so that Regency may either waive such party’s compliance with the terms of this Section 3.2 or seek an appropriate protective order or other remedy and (2) if Regency seeks such a protective order, to provide such cooperation as Regency may reasonably request (at Regency’s sole expense) and (B) the Parties acknowledge and agree that Southern Union or its Affiliates may be required to include or incorporate into its financial statements the financial information described on Schedule I and Southern Union and any such Affiliate shall not publicly disclose such Information in its financial statements until Regency has publicly filed its financial statements containing such information. In the event that Regency waives compliance (in whole or in part) with the terms of this Section 3.02, or such protective order or other remedy is denied, as a result of which Southern Union or its Affiliate is nonetheless legally compelled to disclose such Information, Southern Union or its Affiliate, as the case may be, shall furnish only that portion of the Information that its legal counsel advises is legally required, and Southern Union or its Affiliate shall exercise its reasonable best efforts to preserve the confidentiality of the remainder of the Information. In no event shall Southern Union or its Affiliate oppose action by Regency to obtain a protective order or other relief to prevent the disclosure of Information or to obtain reliable assurance that confidential treatment will be afforded the Information.

Section 3.04 Assignment of Rights. All or any portion of the rights and obligations of Southern Union under this Agreement may be transferred or assigned by Southern Union only in accordance with Section 2.09 of this Agreement.

Section 3.05 Recapitalization, Exchanges, etc. Affecting the Common Units. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all units of Regency or any successor or assign of Regency (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Registrable Securities, and shall be appropriately adjusted for combinations, recapitalizations and the like occurring after the date of this Agreement.

Section 3.06 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have.

-10-

Section 3.07 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 3.08 Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

Section 3.09 Governing Law. The laws of the State of Delaware shall govern this Agreement without regard to principles of conflict of laws.

Section 3.10 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or enforceability of such provision in any other jurisdiction.

Section 3.11 Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by Regency set forth herein. This Agreement supersedes all prior agreements and understandings between the parties with respect to such subject matter.

Section 3.12 Amendment. This Agreement may be amended only by means of a written amendment signed by Regency and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder.

Section 3.13 No Presumption. In the event any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

The holder of any Class F Common Unit shall surrender the certificates evidencing such Class F Common Units for conversion at the office of the General Partner. In such case, the Partnership shall, as soon as practicable thereafter, issue and deliver at such office to the Person in whose name the surrendered Class F Common Units were registered one or more certificates evidencing Common Units, registered in the name of such Person, for the number of Common Units to which such Person shall be entitled as aforesaid.

(g) Section 6.1(d)(iii)(A) is amended and restated to read in its entirety:

(A) If the amount of cash or the Net Agreed Value of any property distributed (except (x) for any difference resulting from the application of Section 5.15(b)(ii) or (y) cash or property distributed or deemed distributed pursuant to Section 12.4) to any Unitholder with respect to its Units for a taxable year is greater (on a per Unit basis) than the amount of cash or the Net Agreed Value of property distributed to the other Unitholders with respect to their Units (on a per Unit basis), then (1) each Unitholder receiving such greater cash or property distribution shall be allocated gross income in an amount equal to the product of (aa) the amount by which the

distribution (on a per Unit basis) to such Unitholder exceeds the distribution (on a per Unit basis) to the Unitholders receiving the smallest distribution and (bb) the number of Units owned by the Unitholder receiving the greater distribution; and (2) the General Partner shall be allocated gross income in an aggregate amount equal to the product obtained by multiplying (aa) the quotient determined by dividing (x) the General Partner’s Percentage Interest at the time in which the greater cash or property distribution occurs by (y) the sum of 100 less the General Partner’s Percentage Interest at the time in which the greater cash or property distribution occurs times (bb) the sum of the amounts allocated in clause (1) above.

(h) Article VI is amended to add a new Section 6.1(d)(xv) as follows:

(xv) Allocations for Class F Common Units.

(B) With respect to any taxable period of the Partnership ending upon, or after, a Book-Up Event or a Book-Down Event occurring no earlier than the taxable year during which the Class F Common Units convert into Common Units or a sale of all or substantially all of the assets of the Partnership occurring after the date of issuance of Class F Common Units, Partnership items of income, gain, loss or deduction for such taxable period shall be allocated (1) to the Partners holding Class F Common Units or converted Class F Common Units that are Outstanding as of the time of such event in proportion to the number of Class F Common Units or converted Class F Common Units held by such Partners, and/or (2) to the Partners holding Common Units (other than Class F Common Units or converted Class F Common Units) that are Outstanding as of the time of such event in proportion to the number of Common Units held by such Partners, until the Capital Account of each Class F Common Unit or converted Class F Common Unit is equal to the Per Unit Capital Amount for a then outstanding Common Unit (other than a converted Class F Common Unit).

(C) With respect to any taxable period of the Partnership ending upon, or after, the transfer of converted Class F Common Units to a Person that is not an Affiliate of the holder, Partnership items of income, gain, loss or deduction for such taxable period shall be allocated (1) to the Partners transferring (or receiving, as applicable) such converted Class F Common Units in proportion to the number of converted Class F Common Units transferred (or received, as applicable) by such Partners, and/or (2) to the Partners holding Common Units (other than Class F Common Units or converted Class F Common Units) that are Outstanding as of the time of such event in proportion to the number of Common Units held by such Partners, until the Capital Account of such converted Class F Common Unit is equal to the Per Unit Capital Amount for a then outstanding Common Unit (other than a converted Class F Common Unit).

(i) Article VI is amended to add a new Section 6.7(g) as follows:

(g) A Unitholder holding a Class F Common Unit that has converted into a Common Unit pursuant to Section 5.15 shall be required to provide notice to the General Partner of the proposed transfer of the converted Class F Common Unit within 30 days prior to such proposed transfer and in no event later than the last Business Day of the calendar year during which such transfer occurs, unless (x) the transfer is to an Affiliate of the holder or (y) by virtue of the application of Section 6.1(d)(xv)(B) to a prior transfer of the Unit or the application of Section 6.1(d)(xv)(A), the General Partner has previously determined, based on advice of counsel, that

the converted Class F Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(g), the General Partner shall take whatever steps are required to provide economic uniformity to the converted Class F Common Units in preparation for a transfer of such Units, including the application of Section 5.5(c)(iii) and/or Section 6.1(d)(xv)(B); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Common Unit Certificates (for this purpose the allocations of income, gain, loss and deductions with respect to Class F Common Units or Common Units will be deemed not to have a material adverse effect on the Unitholders holding Common Units).

Section 3. Ratification of Partnership Agreement. Except as expressly modified and amended herein, all of the terms and conditions of the Partnership Agreement shall remain in full force and effect.

Section 4. General Authority. The appropriate officers of the General Partner are hereby authorized to make such clarifying and conforming changes as they deem necessary or appropriate, and to interpret the Partnership Agreement, to give effect to the intent and purposes of this Amendment.

A G R E E M E N T S

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the Guarantor, the Guarantor agrees as follows:

1. Guarantee. Subject to the terms herein, the Guarantor guarantees to the Holders and the Trustee full and prompt collection of the principal amount due under the Supported Debt, but not any accrued and unpaid interest thereon or any fees or other amounts of any kind whatsoever that shall be due to the Holders by Regency (the “Liabilities”).

2. Guarantee of Collection. This is a guarantee of collection only, and not a guarantee of payment. Notwithstanding any other term or condition of this Guarantee to the contrary, the Guarantor shall not be obligated to make any payment pursuant to this Guarantee unless and until each of the following has occurred: (i) the Trustee or other Holder must use commercially reasonable efforts to obtain judgment against Regency, (ii) the Trustee or other Holder must use commercially reasonable efforts to execute on any judgment obtained against Regency, (iii) following execution of any such judgment, a portion of the sums due under the Supported Debt constituting Liabilities must remain unpaid, (iv) if no bankruptcy proceeding has been commenced with respect to Regency, the Trustee or other Holder shall have brought an action in a court of law having proper subject matter jurisdiction against Regency to collect such Liabilities, obtained a final and non-appealable judgment by such court against Regency in respect of such Liabilities and levied execution of such judgment against the property of Regency, and as a result of such execution received less than payment in full in cash or property of such Liabilities, and (v) if a bankruptcy proceeding has been commenced with respect to Regency, the closing of the bankruptcy proceeding after its administration under 11 U.S.C. Section 350(a) shall have occurred and the Trustee or other Holder shall have received, after all distributions contemplated by such bankruptcy proceeding or otherwise, less than payment in full in cash or property in respect of such Liabilities. For these purposes, the value of any payment made in property shall be equal to the fair market value of such property at the time of such payment.

3. Termination of Guarantee. This Guarantee shall remain in effect and will not terminate until the Liabilities have been paid in full.

4. Waivers. The Guarantor waives (i) notice of acceptance of this Guarantee, (ii) all presentments and protests, and (iii) notice of dishonor.

5. Obligations Absolute. Except as set forth in this Guarantee, the Guarantor’s obligations are in all respects absolute and unconditional and will not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any modification, discharge, renewal or extension of the Liabilities or the Supported Debt, or any amendment, modification or stay of the Trustee’s or other Holder’s rights under the Supported Debt which may occur in any bankruptcy or reorganization case or proceeding concerning Regency, whether permanent or temporary and whether or not assented to by the Trustee or other Holder, (ii) any notice of withdrawal of this Guarantee, at any time and from time to time before, at or after maturity of the Supported Debt, (iii) any determination that any signatures on behalf of Regency on the Supported Debt are not genuine or that the Supported Debt is not the legal, valid and binding obligation of Regency, or (iv) any defenses that Regency may have as to any sums due under the Supported Debt.

6. Waiver of Subrogation. Until the Liabilities have been paid in full, the Guarantor irrevocably waives, relinquishes and renounces any right of subrogation, contribution, indemnity, reimbursement or any claim whatsoever which the Guarantor may have against Regency or any other guarantors liable on the Supported Debt arising out of, or in any way connected with, the documents evidencing, guaranteeing or otherwise relating to the Supported Debt (the “Supported Debt Documents”). The Guarantor will not assert any such claim against Regency or any such guarantor, in any proceeding, legal or equitable, including any bankruptcy, insolvency or reorganization proceeding, before the Trustee and the Holders are paid in full for the Liabilities. This provision will inure to the benefit of and will be enforceable by the Trustee, the Holders, Regency and any such guarantors, and their successors and assigns, including any trustee in bankruptcy or debtor-in-possession. This provision will not prevent the Guarantor from asserting a claim against Regency or any such guarantors once the Liabilities have been fully paid to the Trustee and the Holders. Once the Liabilities have been paid in full, if the Guarantor has made any payment to the Trustee and the Holders under this Guarantee, then the Trustee and the Holders will assign to the Guarantor, to the extent of such payment, the Trustee’s and the Holders’ interest in the Supported Debt Documents and any judgments against Regency.

7. Reinstatement of Guaranteed Liabilities. The Guarantor acknowledges and agrees that the Guarantor’s obligations hereunder shall apply to and continue with respect to any amount paid to the Trustee and the Holders on the Liabilities which is subsequently recovered from the Trustee and the Holders for any reason whatsoever (including, without limitation, as a result of any bankruptcy, insolvency or fraudulent conveyance proceeding), notwithstanding the fact that the Liabilities may have been previously paid in full or this Guarantee terminated, or both.

8. Assignment. The Trustee and the Holders may, from time to time, whether before or after any withdrawal of this Guarantee, without notice to the Guarantor, assign or transfer any or all of the Liabilities or any interest therein; and, notwithstanding any such assignment or transfer or any subsequent assignment or transfer thereof, such Liabilities shall be and remain Liabilities for purposes of this Guarantee, and each and every immediate and successive assignee or transferee of any of the Liabilities or of any interest therein shall, to the extent of the interest of such assignee or transferee in the Liabilities, be entitled to the benefits of this Guarantee to the same extent as if such assignee or transferee were the Trustee or other Holder; provided, however, that, unless the Trustee or Holders shall otherwise consent in writing, the Trustee and the Holders shall have an unimpaired right, prior and superior to that of any such assignee or transferee, to enforce this Guarantee, for the benefit of the Trustee and the Holders, as to that portion of the Liabilities which the Trustee and the Holders have not assigned or transferred.

9. Cumulative Rights; No Waiver. Each and every right granted to the Trustee and the Holders hereunder or under any other document delivered hereunder or in connection herewith, or allowed it by law or equity, shall be cumulative and may be exercised from time to time subject only to the limitations set forth in this Guarantee. No failure on the part of the Trustee and the Holders to exercise, and no delay in exercising, any right shall operate as a waiver thereof, nor shall any single or partial exercise by the Trustee or other Holder of any right preclude any other or future exercise thereof or the exercise of any other right.

10. Interpretation and Construction. Each reference herein to the Trustee and the Holders shall be deemed to include their respective successors and assigns, and each reference to Regency and the Guarantor and any pronouns referring thereto as used herein shall be construed in the singular or plural as the context may require and shall be deemed to include the successors and assigns of Regency and the Guarantor, all of whom shall be bound by the provisions hereof. All references herein to Regency shall be deemed to include any successor or successors, whether immediate or remote, to Regency.

11. Continuing Guarantee. Subject to the limitations herein, this instrument is intended to be a full, complete and continuing guarantee to the Trustee and the Holders to the extent of and for the Liabilities owing by Regency to the Trustee and the Holders from time to time and to be valid and continuous without other or further notice to the Guarantor, notwithstanding the death, disability or dissolution of Regency or any other guarantor, until notice in writing of withdrawal of this Guarantee, signed by the parties hereto or any of them or by the legal representative(s) of a deceased party, has actually been given to the Trustee and the Holders, and then only as to the party or parties signing such notice and to transactions subsequent to the time of such notice; provided, however, that no such notice of withdrawal shall affect or impair any of the agreements and obligations of the Guarantor hereunder with respect to any and all Liabilities existing at the time of actual receipt of such notice by the Trustee and the Holders until paid in full; and shall not affect or impair the Trustee’s or other Holder’s right to recover all expenses paid or incurred by the Trustee or other Holder endeavoring to enforce this Guarantee against the Guarantor. All of the agreements and obligations of the Guarantor under this Guarantee shall, notwithstanding any such notice of withdrawal, remain in effect until all such Liabilities and all such expenses shall have been paid in full.

12. Subsequent Guaranties. No subsequent guarantee by the Guarantor or any other person of the Liabilities shall be deemed to be in lieu of or to supersede this Guarantee, unless otherwise expressly provided therein. The obligation under this Guarantee shall be in addition to any obligation of the Guarantor as endorser of any obligations of Regency.

13. Governing Law. THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

14. Consent to Jurisdiction; Waiver of Jury Trial. The Guarantor irrevocably submits to the exclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York County, and any appellate court from any thereof, for the purposes of any proceeding arising out of this Guarantee or the transactions contemplated hereby (and agrees that no such proceeding relating to this Guarantee or the transactions contemplated hereby shall be brought by it except in such courts). The Guarantor irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any proceeding arising out of this Guarantee or the transactions contemplated hereby in any New York State court or federal court of the United States of America sitting in New York County, and any

appellate court from any thereof, or that any such proceeding brought in any such court has been brought in an inconvenient forum. The Guarantor also agrees that any final and non appealable judgment against it in connection with any proceeding shall be conclusive and binding on it and that such award or judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States. A certified or exemplified copy of such award or judgment shall be conclusive evidence of the fact and amount of such award or judgment. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY ACTION OR PROCEEDING TO ENFORCE OR TO DEFEND ANY RIGHTS UNDER THIS GUARANTEE SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

15. Entire Agreement. This Guarantee constitutes the entire agreement with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written, between the parties related thereto.

If all or any portion of any Supported Debt or Refinancing Supported Debt is repaid or refinanced after the third (3rd) anniversary of the date of this Support Agreement and prior to the applicable Maturity Date, Support Provider may at its sole discretion enter into and provide for a guarantee of collection and/or of payment for the principal amount of all or a portion of any debt of Regency.

(b) Actions Upon Maturity Date. Upon the applicable Maturity Date of any Supported Debt and payment in full of the aggregate principal amount of such Supported Debt, no additional Regency Subsidiary Guarantee shall be permitted to be made by Regency Subsidiary Guarantor with respect to such Supported Debt. Any Supported Debt subject to the Regency Subsidiary Guarantee may be retired or refinanced with debt that is not subject to the Regency Subsidiary Guarantee commencing at any time on or after the scheduled Maturity Date for such Supported Debt.

(c) Extinguishment of Supported Debt. Regency shall use commercially reasonable efforts to extinguish any applicable outstanding Supported Debt on the Maturity Date. Regency Subsidiary Guarantor shall release the Support Provider from any liability or obligation under this Agreement related to the Supported Debt on the applicable Maturity Date for such Supported Debt and shall enter into and execute such documents and instruments as the Support Provider may reasonably request in order to evidence such release, and Regency shall cause Regency Subsidiary Guarantor to take such actions.

(d) Regency Subsidiary Guarantor Limited Activities. Regency Subsidiary Guarantor shall not (i) create, incur, assume or permit to exist any Indebtedness (as defined below) other than the Regency Subsidiary Guarantee or (ii) consummate any transactions other than the Regency Subsidiary Guarantee of the Supported Debt; provided that Regency Subsidiary Guarantor may guarantee other public debt of Regency to the extent Regency Subsidiary Guarantor is required to do so as a subsidiary of Regency and Support Provider shall have no liability for such other public debt or the obligations of Regency Subsidiary Guarantor

7. Covenants of Support Provider.

(a) Net Worth. Support Provider hereby represents to Regency Subsidiary Guarantor and Regency that its existing net worth is equal to or greater than the aggregate principal amount of the Supported Debt and in the event Support Provider disposes of, transfers, or conveys any of its assets, except with respect to distributions permitted in clause (b) below, it shall promptly replace such assets with assets having a net fair market value (after taking into account any Indebtedness to be assumed by the Support Provider in connection with any such transaction) substantially equivalent to or greater than the net fair market value (after taking into account any Indebtedness to be assumed by the Support Provider in connection with any such transaction) of the disposed assets.

(b) Distributions. Support Provider shall be entitled to make distributions of available cash with respect to its equity interests provided Support Provider shall not make a distribution of cash or property to the extent such distribution would constitute a Fraudulent Conveyance (as defined in Section 10) in light of Support Provider’s obligations under this Agreement or otherwise impair Support Provider’s ability to satisfy its obligations under this Agreement.

8. Covenants of the Parties to Maintain Tax Treatment. For so long as any Regency Subsidiary Guarantee is outstanding, the Parties hereto hereby agree that:

(a) Unless otherwise required by law, it is the intent of the Parties to treat Southern Union as the sole partner bearing the economic risk of loss with respect to the Supported Debt pursuant to Treasury Regulation § 1.752-2; provided that, notwithstanding the foregoing, Regency shall not be required to take such position in any taxable year to the extent Regency determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances.

(b) It is the intent of the Parties, that the distribution to Southern Union by Regency of the Cash Consideration (as such term is defined in the Contribution Agreement) be treated as a distribution under Section 731 of the Internal Revenue Code of 1986, as amended (the “Code”), and neither Regency nor any partner of Regency shall take a position inconsistent with such treatment unless otherwise required by law; provided that, notwithstanding the foregoing, Regency shall not be required to take such position in any taxable year to the extent Regency determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances.

(c) Neither Regency nor Regency Subsidiary Guarantor shall (i) modify the Regency Subsidiary Guarantee so as to eliminate or limit the ultimate recourse liability of the Support Provider with respect to the Supported Debt, (ii) merge or consolidate with, or intentionally take any action that would cause, Regency Subsidiary Guarantor to become a corporation for U.S. federal income tax purposes or (iii) except as required by the Supported Debt, cause or permit any other corporation, partnership, person or entity to assume, guarantee, indemnify against or otherwise incur any liability with respect to any Supported Debt.

(d) In the event a subsidiary of Regency that is regarded as separate and apart from Regency for U.S. federal income tax purposes, including but not limited to Pueblo Holdings, Inc. and Pueblo Midstream Gas Corporation, becomes a Subsidiary Guarantor (as such term is defined in the [Senior Notes Indenture/New Credit Facility]) of the Supported Debt or otherwise guarantees the Supported Debt, the Support Provider agrees to indemnify such subsidiary for any amounts that the subsidiary is required to pay pursuant to its guarantee of the Supported Debt.

(e) In the event a partner of Regency guarantees or otherwise incurs any liability with respect to the Supported Debt, the Support Provider agrees to indemnify such partner for any amounts that the partner is required to pay pursuant to its guarantee or liability with respect to the Supported Debt.

9. Subrogation. To the extent that the Support Provider shall have made any payments under this Agreement, the Support Provider shall be subrogated to, and shall acquire, all rights of Regency Subsidiary Guarantor against Regency with respect to such payments, including without limitation, (a) all rights of subrogation, reimbursement, exoneration, contribution or indemnification, and (b) all rights to participate in any claim or remedy of Regency Subsidiary Guarantor or any trustee on behalf of Regency Subsidiary Guarantor against Regency, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from Regency, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right.

10. Fraudulent Conveyance. Notwithstanding any provision of this Agreement to the contrary, it is intended that this Agreement not constitute a Fraudulent Conveyance (as defined below). Consequently, the Support Provider agrees that if this Agreement would, but for the application of this sentence, constitute a Fraudulent Conveyance, this Agreement shall be valid and enforceable only to the maximum extent that would not cause this Agreement to constitute a Fraudulent Conveyance, and this Agreement shall automatically be deemed to have been amended accordingly at all relevant times. For purposes of this Section 10, the term “Fraudulent Conveyance” means a fraudulent conveyance under Section 548 of the United States Bankruptcy Code or a fraudulent conveyance or fraudulent transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, nation or other governmental unit, as in effect from time to time.

11. Cumulative Rights; No Waiver. Each and every right granted to Support Provider hereunder or under any other document delivered hereunder or in connection herewith, or allowed it by law or equity, shall be cumulative and may be exercised from time to time

subject only to the limitations set forth in this Agreement. No failure on the part of Support Provider to exercise, and no delay in exercising, any right shall operate as a waiver thereof, nor shall any single or partial exercise by Support Provider of any right preclude any other or future exercise thereof or the exercise of any other right.

12. Amendments; Waivers.

(a) Except as otherwise expressly set forth herein, this Agreement may not be modified, amended or waived except by an instrument or instruments in writing signed by each of the Parties hereto.

(b) The Parties hereby agree that no provision of Section 1 hereof may be modified, amended or waived without the prior written consent of a majority of the noteholders or lenders under the [Senior Notes Indenture/New Credit Facility] if such modification, amendment or waiver would materially and adversely reduce the benefits to such noteholders or lenders of the support contemplated by Section 1 hereof with respect to such Supported Debt.

13. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. Nothing in this Agreement shall prevent the Support Provider from merging or consolidating with or into any other person so long as the surviving person agrees to be bound by the terms of this Agreement.

14. Third-Party Beneficiaries. This Agreement is for the benefit only of the Support Provider, Regency and Regency Subsidiary Guarantor, the trustee under the Indenture, [the New Credit Facility administrative agents and lenders,] and the subsidiaries and partners of Regency described in Sections 8(d) and 8(e), and is not intended to confer upon any other third party any rights or remedies hereunder, and shall not be construed as for the benefit of any other third party.

15. Notices. Any and all notices, requests or other communications hereunder shall be given in writing and delivered by: (a) regular, overnight, registered or certified mail (return receipt requested), with first class postage prepaid; (b) hand delivery; (c) facsimile transmission; or (d) overnight courier service, if to the Support Provider, at the following address or facsimile number for the Support Provider:
