     2.5 Purchase Price Adjustment.

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

     (i) The Purchase Price Adjustment Amount shall be increased by 49.9% of the amount (if any) by which the Net Working Capital of the Company as of the Closing Date (“Closing Date Net Working Capital”) exceeds negative $83,161,000 (the “Net Working Capital Threshold”);

     (ii) The Purchase Price Adjustment Amount shall be decreased by 49.9% of the amount (if any) by which the Net Working Capital Threshold exceeds Closing Date Net Working Capital;

     (iii) The Purchase Price Adjustment Amount shall be decreased by 49.9% of the amount (if any) by which the Long-Term Debt of the Company as of the Closing Date (“Closing Date Long-Term Debt”) exceeds $798,836,000 (the “Long-Term Debt Threshold”);

     (iv) The Purchase Price Adjustment Amount shall be increased by 49.9% of the amount (if any) by which the Long-Term Debt Threshold exceeds Closing Date Long-Term Debt; and

     (v) The Purchase Price Adjustment Amount shall be increased by 49.9% of the Pre-Closing Capex Amount.

     (b) Not later than ten Business Days prior to the Closing Date, ETE shall prepare and deliver to Regency a preliminary settlement statement (the “Estimated Adjustment Statement”) setting forth (i) an estimated balance sheet of the Company as of the Closing Date, which balance sheet will be prepared in accordance with GAAP, applied consistently with the Company’s past practices (including its preparation of the Financial Statements) (the “Estimated Closing Date Balance Sheet”) based on the most recent financial information of the Company reasonably available to ETE, (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) an estimated calculation of the Pre-Closing Capex Amount (“Estimated Pre-Closing Capex Amount”) and (v) an estimated calculation of the Purchase Price Adjustment Amount. Regency shall have the right, following Regency’s receipt of the Estimated Adjustment Statement, to object thereto by delivering written notice to ETE no later than three Business Days before the Closing Date. To the extent Regency timely objects to the Estimated Adjustment Statement (or any component thereof), Regency and ETE shall attempt to resolve their differences; provided that, if Regency and ETE are unable to resolve any such dispute prior to the Closing Date, then ETE’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 ETE 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 Purchase Price Adjustment Amount that controls for purposes of the payments to be made at the Closing is referred to herein as the “Estimated Purchase Price Adjustment Amount.” If the Estimated Purchase Price Adjustment Amount is a positive number, then at Closing Regency shall wire transfer in immediately available funds an amount equal to the Estimated Purchase Price Adjustment Amount to an account to be designated by ETE before Closing. If the Estimated Purchase Price Adjustment Amount is a negative number, then at Closing ETE shall wire transfer in immediately available funds an amount equal to the absolute value of the Estimated Purchase Price Adjustment Amount to an account to be designated by Regency before Closing.

     (c) Not later than the 90th day following the Closing Date, Regency shall prepare and deliver to ETE a statement (the “Final Adjustment Statement”) setting forth (i) an estimated balance sheet of the Company as of the Closing Date, which balance sheet will be prepared in the same manner as the Estimated Closing Date Balance Sheet (the “Final Closing Date Balance Sheet”) based on the most recent financial information of the Company reasonably available to Regency, (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 actual Pre-Closing Capex Amount (the “Final Pre-Closing Capex Amount”), together with a calculation showing the difference, if any, between the Final Pre-Closing Capex Amount and the Estimated Pre-Closing Capex Amount and (v) the final calculation of the Purchase Price Adjustment Amount. At any time during the 30-day period following receipt of the Final Adjustment Statement (the “Review Period”), ETE may deliver to Regency a written report containing any changes that ETE proposes be made to the Final Adjustment Statement (such written report, an “Objection Notice”). Regency shall provide to ETE such documentation and other data, and, during normal business hours, access to its and the Company’s officers, employees, agents and other personnel as is reasonably necessary to enable ETE to appropriately review the Final Adjustment Statement, including preparing a Final Closing Date Balance Sheet and making the calculations set forth in the first sentence of this Section 2.5(c). ETE shall be deemed to have waived any rights to object to the Final Adjustment Statement unless ETE delivers an Objection Notice to Regency within the Review Period and, if the Review Period expires without ETE so delivering an Objection Notice, then the Final Adjustment Statement shall become final and binding for all purposes of this Agreement. If ETE delivers an Objection Notice to Regency during the Review Period, then ETE and Regency shall attempt to agree on the amount of the actual Purchase Price Adjustment Amount. If such Parties cannot reach agreement within 30 days after the date on which ETE delivered such Objection Notice to Regency, the Parties shall refer the remaining disputed matters necessary to the final determination of the Purchase Price Adjustment Amount to PriceWaterhouseCoopers, or if PriceWaterhouseCoopers 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 ETE and Regency (the “Accounting Firm”). The Accounting Firm shall, if requested by ETE, resolve any disputes under this Section 2.5(c), as well as any disputes under Section 2.5(c) of the Redemption and Exchange Agreement. 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 disputed matters necessary to the determination of the Purchase Price Adjustment Amount submitted by either ETE or Regency to the Accounting Firm, and whether and to what extent, if any, the Purchase Price Adjustment Amount requires adjustment as a result of the resolution of those disputed matters (applying GAAP consistently with the Company’s past practices). The Accounting Firm may not award damages or penalties and shall not have authority to address matters not in dispute between the Parties or necessary to the determination of the final Purchase Price Adjustment

Amount. The Accounting Firm’s determination shall be made within 30 days after submission of the disputed matters and shall be final and binding on all Parties, without right of appeal. In determining the proper amount of the Purchase Price Adjustment Amount, the Accounting Firm shall not increase the Purchase Price Adjustment Amount more than the increase proposed by ETE nor decrease the Purchase Price 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. ETE and Regency shall each bear one-half of the costs and expenses of the Accounting Firm incurred in resolving such disputed matters. The Purchase Price Adjustment Amount as finally determined pursuant to this Section 2.5(c) shall be referred to as the “Final Purchase Price Adjustment Amount.”

     (d) Within ten days after the earlier of (i) the expiration of the Review Period without delivery of any Objection Notice and (ii) the date on which ETE and Regency, or the Accounting Firm, as applicable, finally determine the actual Purchase Price Adjustment Amount (A) if the Final Purchase Price Adjustment Amount exceeds the Estimated Purchase Price Adjustment Amount (such excess, the “ETE Adjustment Payment”), Regency shall wire transfer in immediately available funds an amount equal to the ETE Adjustment Payment to an account designated by ETE and (B) if the Estimated Purchase Price Adjustment Amount exceeds the Final Purchase Price Adjustment Amount (such excess, the “Regency Adjustment Payment”), ETE shall wire transfer in immediately available funds an amount equal to the Regency Adjustment Payment 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, (i) ETE shall wire transfer in immediately available funds an amount equal to the product of (a) the number of Acquired Units multiplied by (b) $0.46 (unless prior to the Closing, Regency shall have declared its distribution in respect of the Preceding Quarter, in which event such number in this clause (b) shall be the amount declared per Regency Common Unit) (such aggregate amount being referred to herein as the “Estimated Preceding Quarter Distribution Amount”) to an account designated by Regency before Closing and (ii) ETE shall wire transfer in immediately available funds an amount equal to the product of (A) the number of Acquired 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 being referred to herein as the “Estimated Pro Rata Closing Quarter Distribution Amount”) to an account designated by Regency before Closing.

     (b) If the Closing occurs after the Record Date for distribution in respect of the Preceding Quarter, at the Closing ETE shall wire transfer in immediately available funds an amount equal to the Estimated Pro Rata Closing Quarter Distribution Amount to an account designated by Regency before Closing.

     (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 distribution in respect of the Preceding Quarter, Regency shall prepare and deliver to ETE a calculation of the Actual Preceding Quarter Distribution Amount (as defined below). Within two Business Days of such delivery, (i) if the Actual Preceding Quarter Distribution Amount exceeds the Estimated Preceding Quarter Distribution Amount, then ETE 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 ETE.

     (d) Not later than the second Business Day following Regency’s declaration of its distribution in respect of the Closing Quarter, Regency shall prepare and deliver to ETE 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, ETE 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 ETE.

     (e) “Actual Preceding Quarter Distribution Amount” means the product of (i) the number of Acquired Units multiplied by (ii) the actual per-unit distribution 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 Units multiplied by (ii) the actual per-unit distribution 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 amounts to be paid by ETE to Regency pursuant to Section 2.6 shall be deemed to be adjustments to the Purchase Price Adjustment Amount.

To the extent practicable, Regency shall make reasonable and appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Any investigation pursuant to this Section 5.4(b) shall be conducted in such manner as not to interfere with the conduct of the business of Regency or its Subsidiaries. Notwithstanding the foregoing, ETE shall not be entitled to perform any intrusive or subsurface investigation or other sampling of, on or under any of the properties of Regency or its Subsidiaries without the prior written consent of Regency. To the fullest extent permitted by Law, Regency and its Representatives and Affiliates shall (A) not be responsible or liable to ETE for personal injuries sustained by ETE’s Representatives in connection with the access provided pursuant to this Section 5.4(b) and (B) shall be indemnified and held harmless by ETE for any losses suffered by any such Persons in connection with any such personal injuries; provided such personal injuries are not caused by the gross negligence or willful misconduct of Regency.

     (e) Calculation of Losses. In calculating amounts payable to any Energy Transfer 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 (i) payments actually recovered by the Indemnified Party under any insurance policy with respect to such Losses and (ii) any prior or subsequent actual recovery by the Indemnified Party from any Person with respect to such Losses.

     (f) Waiver of Certain Damages. Notwithstanding any other provision of this Agreement, in no event shall any Party be liable for punitive, special, indirect, consequential, remote, speculative or lost profits damages of any kind or nature, regardless of the form of action through which such damages are sought, except (i) 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 and (ii) in the case of consequential damages, (A) to the extent an Indemnified Party is required to pay consequential damages to an unrelated third party and (B) to the extent of consequential damages to an Indemnified Party arising from fraud or willful misconduct.

     (g) Sole and Exclusive Remedy. Except for the assertion of any claim based on fraud or willful misconduct, the remedies provided in this Article VIII shall be the sole and exclusive legal remedies of the Parties, from and after the Closing, with respect to this Agreement and the transactions contemplated hereby.

     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 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 in the event 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, in each case, that subjects the Indemnitee to any criminal liability, requires an admission of guilt, wrongdoing or fault on the part of the Indemnitee or imposes any continuing obligation on or requires any payment from the Indemnitee without the Indemnitee’s prior written consent.

     8.5 No Reliance.

     (a) THE REPRESENTATIONS AND WARRANTIES OF ETE CONTAINED IN ARTICLE III CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF ETE TO THE REGENCY PARTIES IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. THE REPRESENTATIONS OF THE REGENCY PARTIES CONTAINED IN ARTICLE IV CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF THE REGENCY PARTIES TO ETE IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EXCEPT FOR SUCH REPRESENTATIONS AND WARRANTIES, NO PARTY OR ANY OTHER PERSON MAKES ANY OTHER EXPRESS OR IMPLIED REPRESENTATION OR WARRANTY WITH RESPECT TO SUCH PARTY OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AND EACH PARTY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, WHETHER MADE BY SUCH PARTY OR ANY OF ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES (INCLUDING WITH RESPECT TO THE DISTRIBUTION OF, OR ANY PERSON’S RELIANCE ON, ANY INFORMATION, DISCLOSURE OR OTHER DOCUMENT OR OTHER MATERIAL MADE AVAILABLE TO ANY PARTY IN ANY DATA ROOM, ELECTRONIC DATA ROOM, MANAGEMENT PRESENTATION OR IN ANY OTHER FORM IN EXPECTATION OF, OR IN CONNECTION WITH, THE TRANSACTIONS CONTEMPLATED BY THIS

AGREEMENT).

     (b) Except as provided in Sections 7.2, 8.1 and 8.2, no Party nor any Affiliate of a Party shall assert or threaten, and each Party hereby waives and shall cause such Affiliates to waive, any claim or other method of recovery, in contract, in tort or under applicable Law, against any Person that is not a Party (or a successor to a Party) relating to the transactions contemplated by this Agreement.

Each of the Parties hereto also agrees that any final and non-appealable judgment against a Party hereto in connection with any Proceeding shall be conclusive and binding on such Party 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.

     9.3 Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY ACTION OR PROCEEDING TO ENFORCE OR TO DEFEND ANY RIGHTS UNDER THIS AGREEMENT SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.
