The Purchased Units are being acquired for the Purchaser’s own account, not as a nominee or agent, and with no present intention of distributing the Purchased Units or any part thereof, and the Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of any securities Laws, without prejudice, however, to the Purchaser’s right at all times to sell or otherwise dispose of all or any part of the Purchased Units pursuant to a registration statement under the Securities Act and applicable state securities Laws or under an exemption from such registration available thereunder (including, if available, Rule 144 under the Securities Act). If the Purchaser should in the future decide to dispose of any of the Purchased Units, the Purchaser understands and agrees (a) that it may do so only (i) in compliance with the Securities Act and applicable state securities Laws, as then in effect, or pursuant to an exemption therefrom (including Rule 144 under the Securities Act) or (ii) in the manner contemplated by any registration statement under the Securities Act pursuant to which such securities are being offered, and (b) that stop-transfer instructions to that effect will be in effect with respect to the Purchased Units. Notwithstanding the foregoing, the Purchaser may at any time transfer Purchased Units to an Affiliate of the Purchaser provided that any such

transaction is exempt from registration under the Securities Act and that such Affiliate agrees to be bound by the terms and conditions of this Agreement.

Section 4.06    Nature of Purchaser. The Purchaser (a) is an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities Act and (b) by reason of its business and financial experience it has such knowledge, sophistication and experience in making similar investments and in business and financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

Section 4.07    Restricted Securities. The Purchaser understands that the Purchased Units are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from Regency in a transaction not involving a public offering and that under such Laws such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, the Purchaser represents that it is knowledgeable with respect to Rule 144 under the Securities Act.

Section 4.08    Receipt of Information. The Purchaser has (a) had access to Regency’s periodic filings with the Commission and (b) been provided a reasonable opportunity to ask questions of and receive answers from Representatives of Regency regarding such matters.

Section 4.09    Legend. It is understood that the Purchased Units, as represented in one or more accounts with DTC, will bear the following legend:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND IS SUBJECT TO THE TERMS OF THE AMENDED AND RESTATED LIMITED PARTNERSHIP AGREEMENT OF REGENCY ENERGY PARTNERS LP. THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF REGENCY ENERGY PARTNERS LP THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF REGENCY ENERGY PARTNERS LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE REGENCY ENERGY PARTNERS LP TO BE TREATED AS AN ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). REGENCY GP LP, THE GENERAL PARTNER OF REGENCY ENERGY PARTNERS LP, MAY IMPOSE

ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF REGENCY ENERGY PARTNERS LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

Section 4.10    Short Selling. The Purchaser has not entered into any short sales of the Common Units owned by it between the time it first began discussion with Regency about the transactions contemplated by this Agreement and the date hereof (it being understood that the entering into of a total return swap shall not be considered a short sale of Common Units).

Section 4.11    Trading Activities. The Purchaser’s trading activities, if any, with respect to the Common Units will be in compliance with all applicable state and federal securities Laws and the rules and regulations of the NYSE.

Section 4.12    Taking of Necessary Actions. The Purchaser shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement. Without limiting the foregoing, Purchaser shall use its commercially reasonable efforts to assist Regency in making all filings and obtaining all consents of Governmental Authorities that may be necessary or, in the reasonable opinion of Regency, advisable for the consummation of the transactions contemplated by the Basic Documents.

Section 5.01    Indemnification by Regency. Regency agrees to indemnify the Purchaser, Energy Transfer Equity, L.P., LE GP, LLC and their respective Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to (a) the breach of any of the representations, warranties or covenants of Regency contained herein, provided such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty and (b) claims made by any third party or governmental agency in any proceeding as to which any Purchaser Related Party is a party or defendant thereto (whether or not such Purchaser Related Party

is a primary defendant) (i) with respect to any breach of fiduciary duty (whether arising at law, in equity or by contract) or (ii) any violation of law or regulation by any Regency Related Party, in the case of (i) or (ii) in connection with the entry into this Agreement and the performance of the transactions contemplated hereby; provided, however, that no Purchaser Related Party shall be entitled to recover special, consequential or punitive damages with respect to claims pursuant to clause (a) of this Section 5.01. Notwithstanding anything to the contrary, consequential damages shall not be deemed to include diminution in value of the Purchased Units, which is specifically included in damages covered by Purchaser Related Parties’ indemnification.

Section 5.02    Indemnification by the Purchaser. The Purchaser agrees to indemnify Regency, the General Partners and their respective Representatives (collectively, “Regency Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Purchaser contained herein, provided such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty, provided, however, that the liability of the Purchaser shall not be greater in amount than the Purchase Price.

Section 5.03    Indemnification Procedure. Promptly after any Regency Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability;

provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) 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 in addition 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 expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrong doing by, the Indemnified Party.

Section 6.01    Interpretation and Survival of Provisions. Article, Section, Schedule, and Exhibit references are to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever Regency has an obligation under a Basic Document, the expense of complying with that obligation shall be an expense of Regency unless otherwise specified. Whenever any determination, consent or approval is to be made or given by the Purchaser, such action shall be in such the Purchaser’s sole discretion unless otherwise specified in this Agreement. If any provision in the Basic Documents is held to be illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid, not binding, or unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect.

Section 6.02    Survival of Provisions. The representations and warranties set forth in Sections 3.02, 3.07, 3.08, 3.11, 3.12, 4.02 and 4.04 hereunder shall survive the execution and delivery of this Agreement indefinitely, and the other representations and warranties set forth herein shall survive for a period of 12 months following the Closing Date regardless of any investigation made by or on behalf of Regency or the Purchaser. The covenants made in this Agreement or any other Basic Document shall survive the Closing of the transactions described herein and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment or repurchase thereof. All indemnification obligations of Regency and the Purchaser and the provisions of Article V shall remain operative and in full force and effect unless such obligations are expressly terminated in a writing referencing that individual Section, regardless of any purported general termination of this Agreement.

Section 6.03    No Waiver; Modifications in Writing.

(a)    Delay. No failure or delay on the part of any Party in exercising any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power, or remedy preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a Party at law or in equity or otherwise.

(b)    Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification, or termination of any provision of this Agreement or any other Basic Document shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification, or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other Basic Document, and any consent to any departure by Regency from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on Regency in any case shall entitle Regency to any other or further notice or demand in similar or other circumstances.

Section 6.04    Binding Effect; Assignment.

(a)    Binding Effect. This Agreement shall be binding upon Regency, the Purchaser, and their respective successors and permitted assigns. Except as expressly provided in this Agreement (including, without limitation, Article V), this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the Parties and their respective successors and permitted assigns.

(b)    Assignment of Rights. All or any portion of the rights and obligations of the Purchaser under this Agreement may be transferred by the Purchaser to any Affiliate of the Purchaser without the consent of Regency.
