     Pursuant to the Support Agreement, dated as of September 3, 2010 (the “Holdings Support Agreement”), by and among EPD, on the one hand, and DD Securities, DFI GP Holdings, DD LLC, EPCO Holdings, DFI and DFI Delaware Holdings L.P. (“DFIDH”) (the “Holdings Affiliated Unitholders”) on the other hand, described in Item 4 of this Schedule, the Holdings Affiliated Unitholders agreed to vote their Units in favor of the Holdings MLP Merger described in Item 4 of this Schedule and certain transactions contemplated thereby. The Holdings Affiliated Unitholders entered into the Holdings Support Agreement as an inducement to EPD to enter into the Holdings MLP Merger Agreement and the Distribution Waiver Agreement described in Item 4 of this Schedule, and the Issuer did not pay any additional consideration to the Holdings Affiliated Unitholders in connection with the voting rights set forth in the Holdings Support Agreement. The descriptions of the Holdings Support Agreement, the Holdings Mergers and the Holdings Merger Agreements in Item 4 of this Schedule are incorporated into this Item 3 by reference.

Item 4. Purpose of the Transaction.

     Item 4 of each of the Original Schedule 13D and the Duncan Trustee Schedule 13D is hereby amended to add each of the following paragraphs:

     On September 3, 2010, EPD, Enterprise Products GP, LLC, (“EPD GP”), Enterprise ETE LLC, a Delaware limited liability company and a wholly owned subsidiary of EPD (“MergerCo”), the Issuer and EPE Holdings entered into an Agreement and Plan of Merger (the “Holdings MLP Merger Agreement”). Pursuant to the Holdings MLP Merger Agreement and immediately prior to the effective time of the Holdings MLP Merger (as defined below), the Issuer’s existing partnership agreement will be amended to provide for the transformation of the approximate 0.01% economic interest of the general partner in the Issuer owned by EPE Holdings into 13,921 Units representing an approximate 0.01% limited partner interest in the Issuer and a non-economic general partner interest in the Issuer (the “transformation”) in accordance with a Fourth Amendment to the First Amended and Restated Agreement of Limited Partnership of the Issuer substantially in the form attached as Annex A to the Holdings MLP Merger Agreement.

16

     Subject to the conditions set forth in the Holdings MLP Merger Agreement, immediately following the transformation and pursuant to the Holdings MLP Merger Agreement and an Agreement and Plan of Merger, dated as of September 3, 2010 (the “Holdings GP Merger Agreement” and, together with the Holdings MLP Merger Agreement, the “Holdings Merger Agreements”), by and among EPD GP, the Issuer and EPE Holdings, EPD GP (a wholly owned subsidiary of the Issuer) will merge with and into the Issuer with the Issuer surviving such merger, thus becoming the general partner of EPD (the “Holdings GP Merger”).

     Subject to the conditions set forth in the Holdings MLP Merger Agreement, immediately following the Holdings GP Merger, at the effective time of the Holdings MLP Merger, the Issuer will merge with and into MergerCo, with MergerCo surviving the merger as a wholly owned subsidiary of EPD (the “Holdings MLP Merger” and, together with the Holdings GP Merger, the “Holdings Mergers”). As a result of the Holdings MLP Merger and pursuant to the Holdings MLP Merger Agreement, EPE Holdings will become the non-economic general partner of EPD and all outstanding Units (other than Units held by the Issuer, EPD or their respective subsidiaries) will be converted into the right to receive common units representing limited partner interests in EPD (“EPD Common Units”). The 21,563,177 EPD Common Units currently owned by the Issuer will become treasury units and cancelled by EPD immediately after the Holdings MLP Merger.

     Under the terms of the Holdings MLP Merger Agreement, all outstanding Units (other than Units held by the Issuer, EPD or their respective subsidiaries) will be cancelled and converted into the right to receive EPD Common Units based on an exchange ratio of 1.5 EPD Common Units per Unit. No fractional EPD Common Units will be issued in the Holdings MLP Merger, and EPE unitholders will, instead, receive cash in lieu of fractional EPD Common Units, if any.

     Under the terms of the Holdings MLP Merger Agreement and a related Sixth Amended and Restated Agreement of Limited Partnership of EPD (substantially in the form attached as Annex C to the Holdings MLP Merger Agreement) to be executed at the closing of the Holdings MLP Merger, the current 2% economic general partner interest and the incentive distribution rights in EPD held by the Issuer will be cancelled, and the non-economic general partner interest in the Issuer held by EPE Holdings will be cancelled and converted into the right to receive the non-economic general partner interest in EPD.

     The Holdings MLP Merger Agreement contains customary representations and warranties and covenants by each of the parties. Completion of the Holdings MLP Merger is conditioned upon, among other things: (1) approval of the Holdings MLP Merger Agreement by EPE unitholders that own at least a majority of the outstanding Units; (2) applicable regulatory approvals; (3) the absence of certain legal injunctions or impediments prohibiting the transactions; (4) the effectiveness of a registration statement on Form S-4 with respect to the issuance by EPD of the EPD Common Units in connection with the Holdings MLP Merger; (5) the receipt of certain tax opinions; (6) approval for the listing of the EPD Common Units on the New York Stock Exchange; (7) the effectiveness of the Holdings GP Merger; (8) the execution of the Sixth Amended and Restated Agreement of Limited Partnership of EPD substantially in the form attached as Annex C to the Holdings MLP Merger Agreement; and (9) the execution of a Distribution Waiver Agreement by certain affiliates of EPCO substantially in the form attached as Annex D to the Holdings MLP Merger Agreement.

     The Holdings MLP Merger Agreement contains provisions granting both EPD and the Issuer the right to terminate the Holdings MLP Merger Agreement for certain reasons, including, among others, if the Holdings MLP Merger does not occur on or before December 31, 2010.

     The Holdings GP Merger Agreement contains customary representations and warranties and covenants by each of the parties. Completion of the Holdings GP Merger is conditioned upon, among other things: (1) the absence of certain legal impediments prohibiting the transactions; (2) applicable regulatory approvals; and (3) the conditions precedent contained in the Holdings MLP Merger Agreement having been satisfied.

     The Holdings GP Merger Agreement contains provisions granting both the EPD GP and the Issuer the right to terminate the Holdings GP Merger Agreement for certain reasons, including, among others, if the Holdings GP Merger does not occur on or before December 31, 2010.

17

     In connection with the Holdings MLP Merger Agreement, EPD entered into the Holdings Support Agreement. Pursuant to the Holdings Support Agreement, the Holdings Affiliated Unitholders, who directly own 105,739,220 Units (representing approximately 76% of the outstanding Units and a sufficient vote for approval of the Holdings MLP Merger Agreement if voted in favor therefor), agreed to vote their Units in favor of the adoption of the Holdings MLP Merger Agreement at any meeting of EPE unitholders. In addition, EPCO Holdings and DFIDH have agreed to execute a Distribution Waiver Agreement substantially in the form attached as Annex D to the Holdings MLP Merger Agreement at the closing of the Holdings MLP Merger. Under the Distribution Waiver Agreement, DFIDH will agree to designate and waive its rights to quarterly distributions of “Available Cash” with respect to a specified number of EPD Common Units over a five-year period: 30,610,000 EPD Common Units during the first four quarters following the closing of the merger; 26,130,000 EPD Common Units during the four quarters thereafter; 23,700,000 EPD Common Units during the four quarters thereafter; 22,560,000 EPD Common Units during the four quarters thereafter; and 17,690,000 EPD Common Units during the four quarters thereafter. EPCO Holdings will agree under the Distribution Waiver Agreement to perform certain obligations in the event DFIDH breaches its obligations under the agreement.

     The Holdings Support Agreement will terminate at 11:59 p.m. (Eastern time) on December 31, 2010 or upon the termination of the Holdings MLP Merger Agreement. In addition, the Holdings Affiliated Unitholders may terminate their obligations under the Holdings Support Agreement, including their obligations to execute and deliver the Distribution Waiver Agreement, (1) after any change in recommendation by the Issuer’s Audit, Conflicts and Governance Committee permitted under the Holdings MLP Merger Agreement, (2) any change in, or a failure to maintain, the Issuer’s Audit, Conflicts and Governance Committee’s “Special Approval” in accordance with the Issuer’s partnership agreement and (3) after the occurrence of certain specified changes in U.S. federal income tax law prior to the closing of the Holdings MLP Merger.

     The foregoing descriptions of the Holdings MLP Merger Agreement, the Holdings GP Merger Agreement, the Holdings Support Agreement and the Distribution Waiver Agreement are qualified in their entirety by reference to the full text of the agreements (including the annexes thereto), which are attached hereto as Exhibits 99.21, 99.22, 99.23 and Annex D to 99.21, respectively, and incorporated herein by reference.

     Other than described above, none of the Reporting Persons has any plans or proposals of the type referred to in clauses (a) through (j) of Item 4 of Schedule 13D, although they reserve the right to formulate such plans or proposals in the future.
