Item 3. Source and Amount of Funds of Other Consideration.

Item 3 of the Original Schedule 13D is hereby amended and supplemented by adding the following thereto:

The Support Agreement described in Item 4 of this Schedule 13D (the terms of which are hereby incorporated by reference) was entered into among Enterprise Products Partners L.P., a Delaware limited partnership (“EPD”), EPE, DD Securities, DFI GP Holdings, DFI, Duncan Family 2000 Trust and Dan Duncan (collectively, the “Unitholders”). The Unitholders entered into the Support Agreement as an inducement to EPD to enter into the MLP Merger Agreement described in Item 4 (the terms of which are hereby incorporated by reference). The Reporting Persons did not pay additional consideration to the Unitholders in connection with the execution and delivery of the Support Agreement and thus no funds were used for such purpose.

As discussed below in Item 4 of this Schedule 13D, the consideration being offered by EPD in the MLP Merger (as defined below) consists exclusively of equity interests of EPD in exchange for the outstanding limited partner interests of TEPPCO.

Item 4. Purpose of the Transaction.

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following thereto:

On June 28, 2009, EPD, EPD GP, Enterprise Sub B LLC, a Delaware limited liability company and a wholly owned subsidiary of EPD (“Merger Sub B”), TEPPCO and TEPPCO GP entered into an Agreement and Plan of Merger (the “MLP Merger Agreement”) providing for the merger of Merger Sub B into TEPPCO (the “MLP

Merger”) with TEPPCO surviving the MLP Merger as a wholly owned subsidiary of EPD, upon the terms and subject to the conditions set forth in the MLP Merger Agreement. Under the terms of the MLP Merger Agreement, all outstanding TEPPCO units, other than 3,645,509 TEPPCO units (the “Designated Units”) owned by an affiliate of EPCO, will be cancelled and converted into the right to receive EPD common units based on an exchange rate of 1.24 EPD common units per TEPPCO unit. The Designated Units will be converted, based on the 1.24 exchange rate, into the right to receive 4,520,431 EPD Class B Units (the “Class B Units”). The Class B Units will not be entitled to regular quarterly cash distributions of EPD for sixteen quarters following the closing of the MLP Merger. The Class B Units will convert automatically into EPD common units on the date immediately following the payment date for the sixteenth distribution following the closing of the MLP Merger. No fractional EPD common units will be issued in the MLP Merger, and TEPPCO unitholders will, instead, receive cash in lieu of fractional EPD common units, if any. A copy of the MLP Merger Agreement is incorporated herein by reference as Exhibit 99.8 hereto and the description of the MLP Merger Agreement contained herein is qualified in its entirety by reference to Exhibit 99.8, which is incorporated herein by reference.

In addition to the MLP Merger, on June 28, 2009, EPD, EPD GP, Enterprise Sub A LLC, a Delaware limited liability company and a wholly owned subsidiary of EPD (“Merger Sub A”), TEPPCO and TEPPCO GP entered into an Agreement and Plan of Merger (“GP Merger Agreement”). Pursuant to the GP Merger Agreement, EPD will acquire 100% of the limited liability company interests in TEPPCO GP (the “TEPPCO GP Interests”) and Merger Sub A will be merged with and into TEPPCO GP, with TEPPCO GP surviving the merger as a wholly owned subsidiary of EPD. Under the terms of the GP Merger Agreement, EPE, the owner of the TEPPCO GP Interests, will receive 1,331,681 EPD common units and an increase in the capital account of EPD GP to maintain EPD GP’s two percent general partner interest in EPD. A copy of the GP Merger Agreement is incorporated herein by reference as Exhibit 99.9 hereto and the description of the GP Merger Agreement contained herein is qualified in its entirety by reference to Exhibit 99.9, which is incorporated herein by reference.

In order to induce EPD to enter into the MLP Merger Agreement, the Unitholders entered into the Support Agreement with EPD, dated as of June 28, 2009 (the “Support Agreement”). Pursuant to the Support Agreement, the Unitholders have agreed to vote all units of TEPPCO owned by them (i) in favor of the adoption of the MLP Merger Agreement, any transactions contemplated by the MLP Merger Agreement and any other action reasonably requested by EPD in furtherance thereof, submitted for the vote or written consent of Unitholders; (ii) against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of TEPPCO contained in the MLP Merger Agreement; and (iii) against any action, agreement or transaction that would impede, interfere with, delay, postpone, discourage, frustrate the purposes of or adversely affect the MLP Merger or the other transactions contemplated by the MLP Merger Agreement. Furthermore, DFI agreed and consented to the receipt of EPD Class B units pursuant to the MLP Merger Agreement in lieu of EPD common units. A copy of the Support Agreement is incorporated herein by reference as Exhibit 99.10 hereto and the description of the Support Agreement contained herein is qualified in its entirety by reference to Exhibit 99.10, which is incorporated herein by reference.

Mr. Duncan also hereby represents that he intends to vote the TEPPCO units owned by him in favor of the MLP Merger.

Except as stated above, no Reporting Person has any plans or proposals of the type referred to in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Original Schedule 13D is hereby amended and supplemented by adding the following thereto:

By virtue of the Support Agreement, certain Reporting Persons may be deemed to share with the Unitholders the power to vote, and may be deemed to be the beneficial owners of, 16,691,550 TEPPCO units, representing approximately 15.9% of the outstanding TEPPCO units (based upon 104,682,604 TEPPCO units outstanding, which TEPPCO has represented and warranted in the MLP Merger Agreement). The Reporting Persons, however, hereby disclaim beneficial ownership of such shares and this Schedule 13D shall not be construed as an admission that the Reporting Persons are, for any or all purposes, the beneficial owners of the securities covered by this Schedule 13D.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Original Schedule 13D is hereby amended and supplemented by adding the following thereto:

The information set forth under Items 3, 4 and 5 and the agreements set forth on Exhibits 99.8, 99.9 and 99.10 are incorporated in this Item 6 by reference.
