    Exhibit
A

     

    SUPPLEMENTAL
INDENTURE (this “Supplemental Indenture”), dated as of March 15, 2006, among
Targa LSNG LP and Targa LSNG GP LLC (each, a “Guaranteeing Subsidiary”),
subsidiaries of Targa Resources, Inc. (or its permitted successor), a Delaware
corporation (the “Company”), Targa Resources Finance Corporation, a Delaware
corporation (the “Co-Issuer”), the other Subsidiary Guarantors (as defined in
the Indenture referred to herein) and Wells Fargo Bank, National Association, as
trustee under the Indenture referred to below (the “Trustee”).

     

    WITNESSETH

     

    WHEREAS,
the Company and the Co-Issuer have heretofore executed and delivered to the
Trustee a senior unsecured indenture (the “Indenture”), dated as of October 31,
2005 providing for the issuance of 81⁄2% Senior Notes Due 2013 (the
“Notes”);

     

    WHEREAS,
the Indenture provides that under certain circumstances a Guaranteeing
Subsidiary shall execute and deliver to the Trustee a supplemental indenture
pursuant to which each Guaranteeing Subsidiary shall unconditionally guarantee
all of the Company’s and the Co-Issuer’s Obligations under the Notes and the
Indenture on the terms and conditions set forth herein (the “Subsidiary
Guarantee”); and

     

    WHEREAS,
pursuant to Section 901 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, each Guaranteeing
Subsidiary 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 SUBSIDIARY GUARANTEE.  Each Guaranteeing Subsidiary hereby agrees
to provide an unconditional Subsidiary Guarantee on the terms and subject to the
conditions set forth in the Note Subsidiary Guarantee and in the Indenture
including but not limited to Article 12 thereof.

     

    3.           NO
RECOURSE AGAINST OTHERS.  No past, present or future director,
officer, employee, incorporator, stockholder or agent of any Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the
Company, the Co-Issuer or any Guaranteeing Subsidiary 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; provided that the foregoing
shall not limit any of the Company’s or the Co-Issuer’s obligations under the
Notes.  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.           GOVERNING
LAW.  THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     

    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 each Guaranteeing Subsidiary, the Co-Issuer and the
Company.

     

    IN
WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to
be duly executed and attested, all as of the date first above
written.
