(B)    For each taxable period, after the application of Section 6.1(d)(iii)(A) but before the application of Section 6.1(d)(iii)(B), and after making the allocations provided for in Section 5.12(b)(ii), the holders of the Class K Units shall be allocated, pro rata in proportion to the number of Class K Units of each such

4

holder, items of Partnership income, gain, loss or deduction (other than from ETP Holdco Items and items of Partnership depreciation, amortization and cost recovery deductions) until the aggregate amount of such items allocated to the holders of the Class K Units pursuant to this Section 5.16(b)(ii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all distributions made to the holders of the Class K Units pursuant to Section 5.16(b)(iii).

(C)     Items of Partnership depreciation, amortization and cost recovery deductions (other than from ETP Holdco Items) for the taxable period shall be allocated to the holders of Class K Units to the extent such items would be allocated to the holders of Class K Units as if each Class K Unit were treated as a Common Unit.

(D)    For each taxable period, after the application of Section 6.1(c)(i)(A) but before the application of Section 6.1(c)(i)(B), Net Termination Gain (other than from ETP Holdco Items) shall be allocated to the holders of the Class K Units, pro rata in proportion to the number of Class K Units of each such holder, until the Capital Account of each Class K Unit is equal to the Class K Unit Issue Price.

(F)    For each taxable period, after the application of Section 6.1(c)(ii)(A), but before the application of Section 6.1(c)(ii)(B), the holders of the Class K Units shall be allocated Net Termination Loss (other than from ETP Holdco Items) until the Capital Account in respect of each Class K Unit has been reduced to zero.

(A)    For each taxable period, no portion of any Partnership cash distribution attributable to ETP Holdco Distributions shall be distributed to the Class K Units.

Each Record Date established for paying a Class K Unit Quarterly Distribution in respect of any Quarter shall be the same Record Date established for any distribution to be made by the Partnership in respect of other Partnership Interests pursuant to Section 6.4 or Section 6.5. If the Partnership is unable to pay the Class K Unit Quarterly Distribution with respect to any Quarter, (A) the amount of such accrued and unpaid distributions will accumulate until paid in full in cash and (B) the balance of such accrued and unpaid distributions shall increase at a rate of 1.5% per annum, compounded quarterly, from the date such distribution was due until the date it is paid. For the avoidance of doubt, except as set forth in this Section 5.16(b)(iii)(B), the Class K Units will not be entitled to receive distributions, including distributions of Available Cash under Section 6.4 and Section 6.5.

(iv)    Voting Rights. Except as set forth in this Section 5.16(b)(iv) and Section 13.3(c) and except to the extent the Delaware Act gives the Class K Units a vote as a class on any matter, the Class K Units shall not have any voting rights. With respect to any matter on which the Class K Units are entitled to vote, each Class K Unit will be entitled to one vote on such matter. The General Partner shall not, without the affirmative vote or written consent of holders of a majority of the Class K Units then Outstanding, amend, alter, modify or change this Section 5.16 (or vote or consent or resolve to take such action).

(v)    Redemption and Conversion Rights. The Class K 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 K Units shall not be evidenced by certificates. Any certificates relating to the Class K Units that may be issued will be in such form as the General Partner may approve. The

6

Class K 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.

(viii)    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 K Units.”

(e) Section 6.1(d)(xiii)(A) of the Partnership Agreement is hereby amended and restated to read in its entirety:

“(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 Series A Preferred Units, Class E Units, Class G Units or Class K 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 Series A Preferred Units, Class E Units, Class G Units or Class K Units) Pro Rata.”

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