Item 5.01 Changes in Control of the Registrant

Based on information provided to DEP Holdings LLC (“DEP Holdings”), the general partner of Duncan Energy Partners L.P. (“Duncan Energy Partners”), upon the death of Dan L. Duncan, voting control of all of the membership interests of Dan Duncan LLC (“Duncan LLC”) has been transferred on March 29, 2010 to three voting trustees pursuant to the Dan Duncan LLC Voting Trust Agreement (the “Trust Agreement”) among Duncan LLC, Dan L. Duncan, as member, and Dan L. Duncan, as initial sole voting trustee.

Duncan LLC owns 100% of the membership interest of EPE Holdings, LLC (“EPE Holdings”), which is the 0.01% general partner of Enterprise GP Holdings L.P. (“Enterprise GP Holdings”).  Enterprise GP Holdings owns 100% of the membership interest of Enterprise Products GP, LLC, the general partner of Enterprise Products Partners L.P. (“Enterprise Products Partners”).  Duncan LLC owns directly 100% of the membership interest in DFI Holdings, LLC (“DFI Holdings”), which owns the sole 1.0% general partner interest in DFI GP Holdings L.P. (“DFI GP Holdings”), and a 4% limited partner interest in DFI GP Holdings.  DFI GP Holdings owns directly 25,162,804 units of Enterprise GP Holdings (representing approximately 18.1% of its outstanding units) and 3,100,000 common units of Enterprise Products Partners (representing less than 1% of its outstanding common units).  Enterprise Products Partners indirectly owns 100% of the membership interest of DEP Holdings.  Enterprise Products Partners also owns indirectly 33,783,587 common units of Duncan Energy Partners (representing approximately 58.6% of its outstanding common units).

The voting trustees under the Trust Agreement consist of up to three trustees, who are initially: (1) Randa Duncan Williams, Mr. Duncan’s oldest daughter who is also an existing director on the board of the general partner of Enterprise GP Holdings; (2) Ralph Cunningham, who is currently the President and Chief Executive Officer of the general partner of Enterprise GP Holdings; and (3) Richard H. Bachmann, who is currently the Executive Vice President and Chief Legal Officer of the general partner of Enterprise Products Partners and the President and Chief Executive Officer of the general partner of Duncan Energy Partners L.P.  Messrs. Cunningham and Bachmann are also currently directors of the general partners of each of Enterprise GP Holdings, Enterprise Products Partners and Duncan Energy Partners.  The address of each of these voting trustees is 1100 Louisiana Street, 10th Floor, Houston, Texas 77002.

Subsequent to Mr. Duncan’s death, the Trust Agreement requires that there always be two “Independent Voting Trustees” serving.  If Mr. Bachmann or Mr. Cunningham fail to qualify or cease to serve, then the substitute or successor Independent Voting Trustee(s) will be appointed by the then-serving Independent Voting Trustee, provided that if no Independent Voting Trustee is then serving or if a vacancy in a trusteeship of an Independent Voting Trustee is not filled within ninety days of the vacancy’s occurrence, the chief executive officer of the general partner of Enterprise Products Partners will appoint the successor Independent Voting Trustee(s).

Subsequent to Mr. Duncan’s death, the Trust Agreement also provides for a “Duncan Voting Trustee.”  The Duncan Voting Trustee is appointed by the children of Mr. Duncan acting by a majority or unanimously if less than three children of Mr. Duncan are then living.  If for any reason no descendent of Mr. Duncan is appointed as the Duncan Voting Trustee, then such trusteeship will remain vacant until such time as a Duncan Voting Trustee is appointed in the manner provided above.  If a Duncan Voting Trustee for any reason ceases to serve, his or her successor shall be appointed by the children of Mr. Duncan acting by majority or unanimously if less than three children of Mr. Duncan are then living.  Randa Duncan Williams is currently the Duncan Voting Trustee.

The voting trustees are required to treat the member of Duncan LLC as the beneficial owner for all purposes whatsoever of the membership interests of Duncan LLC.  However, the voting trustees possess and are entitled to exercise all rights and powers of absolute ownership and to vote, assent or consent with respect thereto and to take party in and consent to any corporate or members’ actions (except those actions, if any, to which the voting trustees may not legally consent) and subject to the provisions of the Trust Agreement, to receive dividends and distributions on the Duncan LLC membership interests.  Except as otherwise provided in the Trust Agreement, all actions taken by the voting trustees are by majority vote.

The voting trustees serve in such capacity without compensation, but they are entitled to incur reasonable charges and expenses deemed necessary and proper for administering the Trust Agreement and to reimbursement and indemnification.
 
2


The Trust Agreement will terminate when (1) the descendants of Dan L. Duncan, and entities directly or indirectly controlled by or held for the benefit of any such descendant, no longer own any capital stock of Enterprise Products Company (formerly named EPCO, Inc.); or (2) upon such earlier date designated by the voting trustees by an instrument in writing delivered to the member of Duncan LLC.
