“5.11    Establishment of Class G Units.

(a)General. The General Partner hereby designates and creates a series of Units to be designated as “Class G Units” and initially consisting of a total of 90,706,000 Class G Units. The initial Class G Units shall be issued to the holders of the 90,706,000 Class F Units currently outstanding, Pro Rata, and the Class F Units shall be cancelled upon the issuance of the Class G Units. In accordance with Section 5.6, the General Partner shall have the power and authority to issue additional Class G Units in the future.

(b)Rights of Class G Units. The Class G Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Initial Capital Account. The initial capital account with respect to each Class G Unit will be equal to the capital account of the Class F Unit retired on the date of the issuance of the corresponding Class G Unit.

(ii) Allocations.

(A) The Class G Units shall not be entitled to receive any allocation of any item of Partnership income, gain, loss, deduction or credit attributable to the Partnership’s ownership of ETP Holdco or the Partnership’s ownership of any indebtedness of ETP Holdco or any of its subsidiaries (the “ETP Holdco Items”), and such ETP Holdco Items (which shall not be included in the computation of Net Income, Net Loss, Net Termination Gain or Net Termination Loss for any taxable period while any Class G Units remain Outstanding) shall instead be specially allocated to the General Partner in an amount equal to the General Partner’s Percentage Interest of such ETP Holdco Items and the remainder to the Unitholders (other than the holders of the Class G Units or the holders of the Class E Units) Pro Rata.

(B) Items of Partnership depreciation, amortization and cost recovery deductions for the taxable period shall be allocated to the Class G Units to the extent that such items would be allocated to the Class G Units if clauses (B) through (E) of this Section 5.11(b)(ii) were not part of this agreement and, solely for purposes of applying Sections 6.1(a), 6.1(b) and the term “Pro Rata” in Section 6.1(d)(xii)(A)(2), the Class G Percentage were equal to the Class G Units’ Share of

4

Additional Book Basis Derivative Items to the extent the item is attributable to an adjustment to property occurring after October 5, 2012, and otherwise the percentage obtained by dividing the number of Class G Units Outstanding by the total number of Units Outstanding (including the Class G Units).

(C) If the Partnership would have had net income for the taxable period, computed in the same manner as Net Income but prior to the application of Section 6.1(d)(xii)(A)(2) and clauses (B) through (D) of this Section 5.11(b)(ii) (“Unitholder Net Income”), the Class G Units shall be allocated an amount of the remaining items of Partnership gross income or gain for the taxable period in a manner such that the Class G Units are allocated items that achieve the same result (taking into account federal income tax consequences) as if the Class G Units were allocated the Class G Percentage of the Unitholder Net Income for such taxable period; provided that the net amount allocated to each Class G Unit for each taxable period shall not exceed the product of (A) the aggregate cash amount distributed to such Class G Unit pursuant to Article VI for such taxable period, multiplied by (B) the quotient obtained by dividing (I) the Partnership’s Net Income that would be allocated to the Unitholders pursuant to Section 6.1(a) for such taxable period if clause (B) above and this clause (C) were not a part of this Agreement by (II) the aggregate cash amount distributed (excluding ETP Holdco Distributions) to the Unitholders (including the holders of the Class G Units) pursuant to Article VI for such taxable period.

(D) If the Partnership would have had net losses for the taxable period, computed in the same manner as Net Losses but prior to the application of Section 6.1(d)(xii)(A)(2) and clause (B) through (D) of this Section 5.11(b)(ii) (“Unitholder Net Losses”), the Class G Units shall be allocated an amount of the remaining items of Partnership gross income, gain, loss or deduction for the taxable period in a manner such that the Class G Units are allocated items that achieve the same result (taking into account federal income tax consequences) as if the Class G Units were allocated the Class G Percentage of the Unitholder Net Losses for such taxable period; provided that items of Partnership gross deduction or loss shall not be allocated to the Class G Units pursuant to this clause (D) to the extent that such allocation would cause any holder of a Class G Unit to have a deficit balance in its Adjusted Capital

5

Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account).

(E) No allocations of Net Income or Net Losses shall be made to the Class G Units pursuant to Section 6.1(a) or Section 6.1(b) following the allocations set forth above.

(F) For each taxable period, each Class G Unit shall be allocated Net Termination Gain pursuant to Section 6.1(c)(i)(B) until the Capital Account of each Class G Unit is equal to its Issue Price. Such allocations will be made prior to any allocations being made to any other Unitholder pursuant to Section 6.1(c)(i)(B) and will be made prior to any allocations being made pursuant to Section 6.1(c)(i)(C). The Class G Units shall be allocated 1% of the remaining aggregate Net Termination Gain, if any, that is to be allocated pursuant to Section 6.1(c)(i) for such taxable period following the allocations made pursuant to Section 6.1(c)(i)(B). No other allocations of Net Termination Gain shall be made to the Class G Units for such taxable period. The Class G Units shall be allocated Net Termination Loss to the same extent as the Common Units. Notwithstanding the foregoing, if ETP Holdco is an asset of the Partnership in the year in which the Partnership is liquidated and the aggregate balance of the Capital Accounts of the Unitholders (other than the holders of the Class E Units and Class G Units) after the allocations under Section 6.1(c) of the Partnership Agreement would be less than the Carrying Value of ETP Holdco, then Net Termination Gain or Net Termination Loss, as the case may be, or if necessary items thereof, shall first be allocated to the Class E Units and Class G Units, in proportion to their respective positive Capital Accounts, to the extent necessary to cause the aggregate balance of the Capital Accounts of the Unitholders (other than the holders of the Class E Units and Class G Units) to equal the Carrying Value of ETP Holdco after all allocations have been made.

(G) Section 6.1(d)(iii)(A) shall not apply to the Class G Units.

(H) Notwithstanding Section 6.2(b)(iii), the General Partner shall apply the principles of Treasury Regulation Section 1.704-3(b) to eliminate Book-Tax Disparities in any Contributed Property received by the Partnership in exchange for the issuance of Class F Units when applying Section 6.2(b)(i) with respect to such Contributed Property.

6

(I) All items of income, gain, loss, deduction or credit attributable to any public indebtedness of the Company assumed, or treated as assumed, by the Partnership in connection with the issuance of the Class F Units shall be specially allocated to the holders of the Class G Units.

(J) For the purposes of effectuating the intent of the foregoing allocation provisions, the General Partner shall have sole discretion to make special allocations of items of Partnership gross income, gain, loss or deductions among the General Partner and the Unitholders as it deems reasonable.

(iii) Distributions.

(A) For each taxable period, no portion of any Partnership cash distribution attributable to (i) any distribution or dividend received by the Partnership from ETP Holdco or the proceeds of any sale of the capital stock of ETP Holdco or (ii) any interest payments received by the Partnership with respect to indebtedness of ETP Holdco or its subsidiaries (such portion of any Partnership cash distributions, the “ETP Holdco Distributions”) shall be distributed to the Class G Units.

(B) For each Quarter in which distributions are made to the Class G Units, (i) for purposes of Sections 6.4 and 6.5, the Percentage Interest of the General Partner shall be computed without taking into account the Class G Units and (ii) any quarterly distributions to the General Partner pursuant to Section 6.4 or Section 6.5 or to the holders of the Incentive Distribution Rights pursuant to clauses (iii)(B), (iv)(B) and (v)(B) of Section 6.4(a) shall equal the amount that would have been distributed to such interests if the distributions to the Class G Units in such Quarter had been made prior to any distributions being made pursuant to Section 6.4 or Section 6.5.

(C) The Class G Units will be entitled to receive the Class G Percentage of the portion of any Partnership cash distributions (other than ETP Holdco Distributions) to be made to the Unitholders pursuant to Article VI and the remaining portion of the Available Cash to be distributed shall be made to the Unitholders (other than the holders of Class G Units) in proportion to their relative Percentage Interests; provided, that the aggregate Partnership distributions made to each Class G Unit for each fiscal year shall not exceed $3.75 (which

7

may, at the General Partner’s discretion, be split equally among the four Quarters of each fiscal year).

(iv) Voting Rights. The Class G Units shall not have any voting rights, except to the extent the Delaware Act gives the Class G Units a vote as a class on any matter. With respect to any matter on which the Class G Units are entitled to vote, each Class G Unit will be entitled to one vote on such matter.

(v) Redemption and Conversion Rights. The Class G Units will be perpetual and shall not have any rights of redemption or conversion.

(vi) Certificates; Book-Entry. Unless the General Partner shall determine otherwise, the Class G Units shall not be evidenced by certificates. Any Certificates relating to the Class G Units that may be issued will be in such form as the General Partner may approve. The Class G Units, subject to the satisfaction of any applicable legal, regulatory and contractual requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other Units.

(vii) Registrar and Transfer Agent. Unless and until the General Partner determines to assign the responsibility to another Person, the General Partner will act as the registrar and transfer agent for the Class G Units.

(viii) Continuing Liability for Assumed Company Debt. The Company shall continue to be liable for any public indebtedness assumed, or treated as assumed, by the Partnership as a result of the contribution of assets to the Partnership by the Company or its subsidiaries in exchange for Class F Units. The Company, on behalf of itself and its subsidiaries, shall contribute cash to the Partnership immediately prior to the payment by the Partnership of any amount due with respect to such indebtedness, including principal, interest or any other amounts due pursuant to the terms of such indebtedness, in an amount equal to the amount due by the Partnership with respect to such indebtedness. Any amount paid by the Company directly to the holders of any securities evidencing such indebtedness shall for federal income tax purposes be treated as a capital contribution of such amount to the Partnership by the Company and a payment by the Partnership of such amount to the holders of such securities. The capital accounts of the Class G Units shall be increased by the amount of such cash contributions, or deemed cash contributions, but no additional Class G Units shall be issued to the Company or its subsidiaries as a result of such additional cash contributions. The Company shall provide such additional documentation setting forth such obligation as requested by the Partnership, including but not limited to the issuance to the Partnership of a promissory note of the Company.

8

(c)Section 6.1(d)(iii)(A) shall not apply to the Class E Units.

(d)Section 6.1(d)(xiii)(A) is hereby amended and restated as follows:

“(A)    The Class E Units shall not be entitled to receive any allocation of any ETP Holdco Items, and such ETP Holdco Items (which shall not be included in the computation of Net Income, Net Loss, Net Termination Gain or Net Termination Loss for any taxable year while any Class E Units or Class G Units remain Outstanding) shall instead be specifically allocated to the General Partner in an amount equal to the General Partner’s Percentage Interest of such ETP Holdco Items and the remainder to the Unitholders (other than the holders of Class E Units or Class G Units) Pro Rata.”    

(e)Section 6.3(e)(ii) of the Partnership Agreement is hereby amended by replacing the second parenthetical with the following: “(other than the holders of Class E or Class G Units)”.

(f) The allocation provisions set forth herein applicable to the Class G Units shall apply for any allocations to the holders of the Class G Units that are attributable to their ownership of the Class F Units, effective as of October 5, 2012, and shall remain in effect for as long as the Class G Units remain outstanding, unless amended. The amendments of the allocation provisions set forth herein applicable to the Class E Units shall apply for any allocations to the holders of the Class E Units that are attributable to their ownership of the Class E Units, effective as of January 1, 2012, and shall remain in effect for as long as the Class E Units remain outstanding, unless amended.

Section 2.    Except as hereby amended, the Partnership Agreement shall remain in full force and effect.
