Section 2.01.    Right of First Refusal.

(a)    If ETP or any of its Subsidiaries (such entity, a “Selling Party”) receives a bona fide offer from a third party for a Transfer of all or any portion of (i) the membership interests of Sunoco GP owned directly or indirectly by the Selling Party, (ii) the SXL GP Interest owned by the Selling Party or (iii) the SXL IDRs owned by the Selling Party (in each case, the “Subject Interest”), and the Selling Party wishes to accept such offer, the Selling Party (and ETP on behalf of the Selling Party) must notify the ETE Parties in writing within twenty (20) days after receiving such offer (the “Sale Notice”). The Sale Notice must include a complete description of the purchase price and other terms and conditions of the transaction in which the Selling Party proposes to Transfer the Subject Interest, including the name of the proposed Transferee and other consideration specified in the offer. The ETE Parties shall have thirty (30) days (the “ROFR Option Period”) after receiving the Sale Notice in which to advise the Selling Party in writing (the “ROFR Acceptance Notice”) whether or not they will acquire all of the Subject Interest upon the terms and conditions contained in the Sale Notice. A failure to advise the Selling Party in writing before the expiration of the ROFR

Option Period as to whether or not the ETE Parties will acquire all of the Subject Interest pursuant to the preceding sentence shall be deemed to constitute an election not to acquire the Subject Interest.

(b)    If, during the ROFR Option Period, the ETE Parties elect to acquire the Subject Interest at the price and subject to the terms and conditions set forth in the Sale Notice (upon such election, the “ROFR Accepting Party”), then such ROFR Accepting Party and the Selling Party shall close such transaction no later than the later to occur of (A) the closing date set forth in the Sale Notice and (B) ninety (90) days after the Selling Party receives the ROFR Acceptance Notice.

(c)    The right of first refusal created in this Section 2.01 is an option to acquire all, but not less than all, of the Subject Interest offered for sale by the Selling Party. If the ETE Parties elect not to acquire the Subject Interest or the ETE Parties fail to make an election before the expiration of the ROFR Option Period, the Selling Party may Transfer the Subject Interest to the proposed Transferee named in the Sale Notice upon the terms and conditions described in the Sale Notice and in accordance with this Section 2.01(c). If such Transfer does not occur on substantially the same terms and conditions set forth in the Sale Notice, or if such Transfer is not consummated within one hundred twenty (120) days after the ETE Parties’ election not to acquire the Subject Interest, then such Transfer shall be null and void ab initio and the Selling Party must again satisfy all of the requirements of this Section 2.01.

(d)    Upon consummation of any Transfer of any Subject Interest in accordance with this Section 2.01 (whether to an ETE Party or any other Person), such Transferee shall enter into a joinder agreement to become a Party to and be bound by this Agreement and shall thereafter have all of the rights and obligations as a Selling Party hereunder other than with respect to this Section 2.01 and Section 2.02; provided, however, that this Agreement shall be amended as necessary to provide that only the Parties who collectively own a controlling interest in the SXL GP Interest (whether directly or indirectly by owning membership interests of Sunoco GP) will be obligated to provide ETE the governance rights set forth in Section 2.03 that relate to SXL. Notwithstanding the foregoing, all Transfers pursuant to this Section 2.01 must comply with the terms of this Agreement.

Section 2.02.    SXL GP Interest Purchase Right.

(a)    If a Selling Party receives a bona fide offer from a third party for a Transfer of 50% or more of the SXL IDRs and the ETE Parties have elected to acquire all of such SXL IDRs in accordance with Section 2.01, the ETE Parties shall also have the option to acquire all, but not less than all, of the SXL GP Interest, provided that such interest is then owned by ETP or any of its Subsidiaries (the owner of the SXL GP Interest at such time referred to as the “SXL GP Interest Owner”). The ETE Parties shall advise the SXL GP Interest Owner in writing (the “Purchase Right Acceptance Notice”) of their intent to purchase the SXL GP Interest prior to the expiration of the ROFR Option Period. A failure to advise the SXL GP Interest Owner of its election prior to the expiration of the ROFR Option Period shall be deemed to constitute an election not to acquire the SXL GP Interest.

(b)    If the ETE Parties elect to acquire the SXL GP Interest, the transaction shall close within ninety (90) days after the SXL GP Interest Owner receives the Purchase Right Acceptance Notice. The purchase price for the SXL GP Interest shall be the fair market value of such interest. For purposes of this Section 2.02(b), the fair market value of the SXL GP Interest shall be determined by agreement among the SXL GP Interest Owner and the ETE Parties or, failing agreement within thirty (30) days following the date on which the SXL GP Interest Owner receives the Purchase Right Acceptance Notice, by an independent investment banking firm or other independent expert selected by the SXL GP Interest Owner and the ETE Parties, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If the SXL GP Interest Owner and the ETE Parties cannot agree upon one independent investment banking firm or other independent expert within forty-five (45) days following the date on which the SXL GP Interest Owner receives the Purchase Right Acceptance Notice, then the SXL GP Interest Owner shall designate an independent investment banking firm or other independent expert and the ETE Parties shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert within ten (10) days following the date of designation, which third independent investment banking firm or other independent expert shall determine the fair market value of the SXL GP Interest.

(c)    ETP shall use its best efforts to cause its Subsidiaries (including Sunoco GP and SXL) to comply with Section 2.01 and Section 2.02 as if such Subsidiaries were parties hereto and bound hereby.

Section 2.03.    Governance Rights.

(a)    ETP, in its capacity as a member of Sunoco GP, shall not consent to or cause Sunoco GP to take or cause SXL to take any of the following actions without having obtained the prior written consent of ETE:

(b)    ETP shall not take any action to cause the Board of Directors of Sunoco GP (the “SXL Board”) to take any of the following actions on behalf of Sunoco GP, in its capacity as the general partner of SXL, without having obtained the prior written consent of ETE:

Each of ETE and ETP agree that, without having obtained the prior written consent of the other party, neither ETE or any of its Controlled Subsidiaries (other than ETP, its general partner or any of their respective Controlled Subsidiaries) nor ETP or any of its Controlled Subsidiaries (other than SXL, Sunoco GP or any of their respective Controlled Subsidiaries) will enter into any Affiliate Contract with SXL, Sunoco GP or any of their respective Controlled Subsidiaries.

Section 2.05.    Information Rights.

(a)    Subject to Section 2.05(e), ETP shall provide the ETE Parties with the following information, in each case, to the extent available to ETP:

(b)    The annual and quarterly financial statements described above will include a description of the business activities that took place during the period covered by the financial statements and a summary of SXL’s business plan for the following quarter.

(c)    Subject to Section 2.05(e), ETP shall permit the ETE Parties or their respective representatives to inspect any of the books of account and other records of SXL to which ETP has access as the controlling member of Sunoco GP and to discuss the business and affairs of SXL with Sunoco GP’s officers and SXL’s independent public accountants, all subject to customary confidentiality provisions and at such reasonable times during Sunoco GP’s usual business hours and upon reasonable prior notice (which shall not be less than twenty-four (24) hours).

(d)    The ETE Parties shall not, directly or indirectly, disclose to any Person any confidential information provided to the ETE Parties pursuant to this Section 2.05 (“Information”), which has not generally become available to the public, other than as a result of a breach of this Agreement. Notwithstanding the foregoing, in the event that the ETE Parties are required by Law or applicable stock exchange rules to disclose any Information, such ETE Party shall (i) notify ETP

as promptly as practicable of the existence, terms and circumstances surrounding such a request, so that ETP may either waive such ETE Party’s compliance with the terms of this Section 2.05(d) or seek an appropriate protective order or other remedy and (ii) if ETP seeks such a protective order, to provide such cooperation as ETP may reasonably request (at ETP’s sole expense).

(e)    Notwithstanding anything else in this Section 2.05, in the event that (i) the Board of Directors of Sunoco GP determines in good faith, with the advice of outside legal counsel, that the provision by Sunoco GP to ETP of any of the information set forth in this Section 2.05 would be reasonably likely to result in a breach of Sunoco GP’s obligations under the SXL Partnership Agreement or of any applicable Law or (ii) the Board of Directors of ETP GP LLC determines in good faith, with the advice of outside legal counsel, that the provision by ETP to ETE of any of the information set forth in this Section 2.05 would be reasonably likely to result in a breach of Sunoco GP’s obligations under the SXL Partnership Agreement or of any applicable Law, then ETP shall have no obligation to provide such information to ETE.
