Item 1.01. Entry into a Material Definitive Agreement.

On June 14, 2012, DCP Midstream Operating, LP (the “Operating Partnership”) and DCP Midstream Partners, LP (the “Partnership”) entered into a third supplemental indenture (the “Third Supplemental Indenture”) among the Operating Partnership, the Partnership and The Bank of New York Mellon Trust Company, N.A. as trustee, amending the base indenture dated as of September 30, 2010 (the “Base Indenture”), as supplemented by the First Supplemental Indenture dated September 30, 2010, and the Second Supplemental Indenture dated March 13, 2012. The Third Supplemental Indenture eliminated certain rights of the Partnership to release the Partnership’s guarantee under the notes issued pursuant to the Base Indenture, and certain rights of any guarantors that are subsidiaries of the Operating Partnership to release any prospective guarantee that such subsidiaries enter into under such notes. A copy of the Third Supplemental Indenture is attached to this Current Report on Form 8-K as Exhibit 4.1 and is incorporated herein by reference.

Item 3.03. Material Modification to Rights of Security Holders.

The information set forth under Item 1.01 above is incorporated by reference into this Item 3.03.

Item 8.01. Other Events.

On March 30, 2012, the Partnership acquired the remaining 66.67% interest in DCP Southeast Texas Holdings, GP, or Southeast Texas, and commodity derivative instruments related to the Southeast Texas storage business. Prior to the acquisition of the additional interest in Southeast Texas, the Partnership owned a 33.33% interest which the Partnership accounted for as an unconsolidated affiliate using the equity method. The acquisition of the remaining 66.67% interest in Southeast Texas represents a transaction between entities under common control and a change in reporting entity. Transfers of net assets or exchanges of shares between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior years are retrospectively adjusted to furnish comparative information similar to the pooling method. As a result, the Partnership is providing consolidated financial statements to include our 100% interest in the financial results of Southeast Texas and the natural gas commodity derivatives associated with the storage business for all periods presented.

Included herein as Exhibit 99.3 are the audited consolidated financial statements of the Partnership as of December 31, 2011 and 2010 and for the years ended December 31, 2011, 2010 and 2009. These audited consolidated financial statements give retrospective effect to the acquisitions of the 100% interest in Southeast Texas. These audited consolidated financial statements replace Item 8 and the consolidated financial statements of DCP Southeast Texas Holdings, GP included in Item 15 in the Partnership’s 2011 Form 10-K filed with the SEC on February 29, 2012. This 8-K does not affect Item 15 of the Form 10-K as it pertains to the audited consolidated financial statements of Discovery Producer Services LLC. Also, included herein as Exhibit 99.1 is the Selected Financial Data, which replaces Item 6 in the Partnership’s 2011 Form 10-K filed with the SEC on February 29, 2012. Included herein as Exhibit 99.2 is Management’s Discussion and Analysis of Financial Condition and Results of Operations, which relates to the audited consolidated financial statements, and replaces Item 7 in the Partnership’s 2011 Form 10-K filed with the SEC on February 29, 2012. Also, included herein as Exhibit 12.1 is the Ratio of Earnings to Fixed Charges, which replaces Exhibit 12.1 in the Partnership’s 2011 Form 10-K filed with the SEC on February 29, 2012.
