Rigrodsky & Long, P.A. Investigates Duncan Energy Partners L.P.'s Buyout Offer From Enterprise Products Partners L.P.

Rigrodsky & Long, P.A. announces that it is investigating potential claims against the board of directors of Duncan Energy Partners, L.P. (“Duncan” or the “Company”) (NYSE: DEP) concerning the Company’s receipt of a proposal from Enterprise Product Partners L.P. (“Enterprise”) (NYSE: EPD) to acquire all of the outstanding common units of Duncan in a unit-for-unit exchange valued at approximately $2.4 billion (the “Proposal”).

The investigation concerns whether Duncan’s board of directors is adequately shopping the Company and working to obtain the best price possible for Duncan’s unitholders.  Enterprise already owns 100% of Duncan’s general partner and owns approximately 58% of Duncan’s outstanding common units.

The Proposal contemplates the acquisition of all of the outstanding common units of Duncan in a unit-for-unit exchange whereby Enterprise has proposed consideration of 0.9545 Enterprise common units for each issued and outstanding publicly-held Duncan common unit.  The consideration offered by Enterprise represents a value of approximately $42.00 for each Duncan common unit based on the 10-day average closing price of Duncan common units and the closing price of Enterprise common units on February 18, 2011.

If you own Duncan common units and purchased your common units before February 23, 2011, if you have information or would like to learn more about these claims, or if you wish to discuss these matters or have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Seth D.
