The Partnership intends to use the net proceeds of this offering, together with the net proceeds from a private placement of preferred units of the Partnership and borrowings under its asset-based revolving credit facility, to fund the cash purchase price of its previously announced acquisition of all of the issued and outstanding membership interests in CDM Resource Management LLC and CDM Environmental & Technical Services LLC from Energy Transfer Partners, L.P. for aggregate consideration of approximately $1.7 billion consisting of units representing limited partner interests in the Partnership and an amount in cash equal to $1.225 billion, subject to certain adjustments (the “CDM Acquisition”).

Unless they are registered, the notes may be offered only in transactions that are exempt from registration under the Securities Act and applicable state securities laws. The notes will be offered only to qualified institutional buyers under Rule 144A under the Securities Act and to non-U.S. persons outside the United States under Regulation S of the Securities Act. The notes will not be listed on any securities exchange or automated quotation system.

This press release does not constitute an offer to sell or a solicitation of an offer to buy the securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
