Third Supplemental Indenture

 Exhibit 4.4 
 THIRD SUPPLEMENTAL INDENTURE 
 Third Supplemental Indenture (this
“Supplemental Indenture”), dated as of May 22, 2012, among each of Zephyr Gas Services I LLC, a Delaware limited liability company, CDM Resource Management I LLC, a Delaware limited liability company, and Regency Ranch
JV LLC, a Delaware limited liability company (collectively, the “Guaranteeing Subsidiaries”), Regency Energy Partners LP, a Delaware limited partnership (“Regency Energy Partners”), Regency Energy
Finance Corp., a Delaware corporation (“Finance Corp.” and, together with Regency Energy Partners, the “Issuers”), the other Guarantors (as defined in the Indenture referred to herein) and Wells Fargo
Bank, National Association, as trustee (the “Trustee”) under the Indenture referred to below. 
 W I T
N E S S E T H: 
 WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an Indenture (as
supplemented to date, the “Indenture”), dated as of May 20, 2009, providing for the issuance of the 9 3/8% Senior Notes due 2016 (the “Notes”); 

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiaries shall execute and deliver to the
Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiaries shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the
“Note Guarantees”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee
is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing
and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the
Indenture. 
 2. Agreement to Guarantee. The Guaranteeing Subsidiaries hereby agree to provide an unconditional Guarantee
on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof. 
 3. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guaranteeing Subsidiaries, as such, shall have any liability for any
obligations of the Issuers or any Guaranteeing Subsidiaries under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder
of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it
is the view of the SEC that such a waiver is against public policy. 

 4. NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED
TO CONSTRUE THIS SUPPLEMENTAL INDENTURE. 
 5. Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. 
 6.
Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof. 

7. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of
this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiaries and the Issuers.
