Exhibit 4.2

SECOND SUPPLEMENTAL INDENTURE

          Second Supplemental Indenture (this “Supplemental Indenture”), dated as of May 24, 2011, among
each of Regency Midstream LLC, a Delaware limited liability company, and Regency Texas Pipeline
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 U.S. Bank
National Association, as trustee under the Indenture referred to below (the “Trustee”).

W I T N E S S E T H

          WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an Indenture, dated
as of October 27, 2010, as amended and supplemented by the First Supplemental Indenture dated as of
October 27, 2010 (as amended and supplemented, the “Indenture”), providing for the issuance of the
6 7/8% Senior Notes due 2018 (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 Guarantee”); 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, each of 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 XIV thereof.

          3. No Recourse Against Others. No past, present or future director, officer, partner,
member, employee, incorporator, manager or unit holder or other owner of Equity Interest 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 each of the Guaranteeing
Subsidiaries and the Issuers.

executed as of the date first above written.

with Regency Energy Partners, the “Issuers”), the Guarantors (as defined below) and U.S. Bank
National Association, as trustee (herein called the “Trustee”).

RECITALS:

          WHEREAS, the Issuers and the Guarantors have executed and delivered to the Trustee an
Indenture, dated October 27, 2010 (the “Base Indenture” and as amended and supplemented by this
Third Supplemental Indenture, in respect of the Notes (as defined below), the “Indenture”),
providing for the issuance by the Issuers from time to time of their Debt Securities (as defined in
the Base Indenture);

          WHEREAS, the Issuers have duly authorized and desire to cause to be established pursuant to
the Base Indenture and this Third Supplemental Indenture a new series of Debt Securities;

          WHEREAS, Sections 2.01 and 2.03 of the Base Indenture permit the execution of supplemental
indentures to establish the form and terms of Debt Securities of any series;

          WHEREAS, pursuant to Section 9.01 of the Base Indenture, the Issuers have requested that the
Trustee join in the execution of this Third Supplemental Indenture to establish the form and terms
and to provide for the issuance, of a series of senior notes designated as their 6 1/2% Senior
Notes due 2021 in an aggregate principal amount of $500,000,000 (the “Initial Notes”);

          WHEREAS, from time to time subsequent to the date hereof, the Issuers may, if permitted to do
so pursuant to the terms of the Indenture, the Initial Notes and the terms of their other
indebtedness existing on such future date, issue additional senior notes of the same series as the
Initial Notes in accordance with this Third Supplemental Indenture (the “Additional Notes” and,
together with the Initial Notes, the “Notes”), pursuant to this Third Supplemental Indenture; and

          WHEREAS, all things necessary have been done to make the Notes, when executed by the Issuers
and authenticated and delivered hereunder and under the Base Indenture and duly issued by the
Issuers, the valid obligations of the Issuers, and to make this Third Supplemental Indenture a

          NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for
other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree, for the equal and proportionate benefit of all
Holders of the Notes, as follows:

ARTICLE I

RELATION TO BASE INDENTURE; DEFINITIONS

Section 1.01 Relation to Base Indenture.

          With respect to the Notes, this Third Supplemental Indenture constitutes an integral part of
the Base Indenture.

 

 

Section 1.02 Generally.

          The rules of interpretation set forth in the Base Indenture shall be applied hereto as if set
forth in full herein.

Section 1.03 Definitions of Certain Terms.

          (a) Capitalized terms used herein and not otherwise defined herein shall have the respective
meanings ascribed thereto in the Base Indenture.

          (b) The following terms shall have the definitions set forth below as used in this Third
Supplemental Indenture and in the provisions of the Base Indenture amended hereby, and for purposes
of this Third Supplemental Indenture and the provisions of the Base Indenture amended hereby only,
shall replace any such definitions of such capitalized terms set forth in the Base Indenture.

          “Acquired Debt” means, with respect to any specified Person:

     (1) Indebtedness of any other Person existing at the time such other Person is merged
with or into or becomes a Subsidiary of such specified Person, whether or not such
Indebtedness is incurred in connection with, or in contemplation of, such other Person
merging with or into, or becoming a Subsidiary of, such specified Person, but excluding
Indebtedness which is extinguished, retired or repaid in connection with such Person merging
with or becoming a Subsidiary of such specific Person; and

     (2) Indebtedness secured by a Lien encumbering any asset acquired by such specified
Person.

          “Affiliate” of any specified Person means any other Person directly or indirectly controlling
or controlled by or under direct or indirect common control with such specified Person. For
purposes of this definition, “control,” as used with respect to any Person, means the possession,
directly or indirectly, of the power to direct or cause the direction of the management or policies
of such Person, whether through the ownership of voting securities, by agreement or otherwise;
provided that beneficial ownership of 10% or more of the Voting Stock of a Person will be deemed to
be control; provided, further, that any third Person which also beneficially owns 10% or more of
the Voting Stock of a specified Person shall not be deemed to be an Affiliate of either the
specified Person or the other Person merely because of such common ownership in such specified
Person. For purposes of this definition, the terms “controlling,” “controlled by” and “under
common control with” have correlative meanings.

          “Agent” means any Registrar or Paying Agent.

          “Applicable Premium” means, with respect to any Note on any Redemption Date, the greater of:

     (1) 1.0% of the principal amount of the Note; or

     (2) the excess of: (a) the present value at such Redemption Date of (i) the redemption
price of the Note at July 15, 2016 (such redemption price being set forth in the table
appearing in Section 3.07 hereof) plus (ii) all required interest payments due on the Note
through July 15, 2016 (excluding accrued but unpaid interest to the Redemption Date),
computed using a dis-

-2-

 

count rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over
(b) the principal amount of the Note.

          “Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial
interests in any Global Note, the rules and procedures of the Depositary, Euroclear System and
Clearstream Banking, S.A. that apply to such transfer or exchange.

          “Asset Sale” means:

     (1) the sale, lease, conveyance or other disposition of any properties or assets;
provided, however, that the sale, lease, conveyance or other disposition of all or
substantially all of the properties or assets of Regency Energy Partners and its
Subsidiaries taken as a whole will be governed by Section 4.15 hereof and/or Section 10.01
hereof and not by Section 4.10 hereof; and

     (2) the issuance of Equity Interests in any of Regency Energy Partners’ Restricted
Subsidiaries or the sale of Equity Interests in any of its Restricted Subsidiaries.

     Notwithstanding the preceding, none of the following items will be deemed to be an Asset Sale:

     (1) any single transaction or series of related transactions that involves properties
or assets having a Fair Market Value of less than $10.0 million;

     (2) a transfer of properties or assets between or among Regency Energy Partners and its
Restricted Subsidiaries;

     (3) an issuance or sale of Equity Interests by a Restricted Subsidiary of Regency
Energy Partners to Regency Energy Partners or to a Restricted Subsidiary of Regency Energy
Partners;

     (4) the sale or lease of products, services or accounts receivable in the ordinary
course of business and any sale or other disposition of damaged, worn-out or obsolete
properties or assets in the ordinary course of business;

     (5) the sale or other disposition of cash or Cash Equivalents, Hedging Obligations or
other financial instruments in the ordinary course of business;

     (6) a Restricted Payment that does not violate Section 4.07 hereof or a Permitted
Investment;

     (7) any trade or exchange by Regency Energy Partners or any Restricted Subsidiary of
properties or assets of any type for properties or assets of any type owned or held by
another Person, including any disposition of some but not all of the Equity Interests of a
Restricted Subsidiary in exchange for assets or properties and after which the Person whose
Equity Interests have been so disposed of continues to be a Restricted Subsidiary, provided
that the Fair Market Value of the properties or assets traded or exchanged by Regency Energy
Partners or such Restricted Subsidiary (together with any cash or Cash Equivalents and
liabilities assumed) is reasonably equivalent to the Fair Market Value of the properties or
assets (together with any cash or Cash Equivalents and liabilities assumed) to be received
by Regency Energy Partners or such Re-

-3-

 

stricted Subsidiary; and provided further that any cash received must be applied in
accordance with Section 4.10 hereof; and

     (8) the creation or perfection of a Lien that is not prohibited by Section 4.12 hereof
and any disposition in connection with a Permitted Lien.

          “Attributable Debt” in respect of a sale and leaseback transaction means, at the time of
determination, the present value of the obligation of the lessee for net rental payments during the
remaining term of the lease included in such sale and leaseback transaction including any period
for which such lease has been extended or may, at the option of the lessor, be extended. Such
present value shall be calculated using a discount rate equal to the rate of interest implicit in
such transaction, determined in accordance with GAAP; provided, however, that, if such sale and
leaseback transaction results in a Capital Lease Obligation, the amount of Indebtedness represented
thereby will be determined in accordance with the definition of “Capital Lease Obligation.”

          “Available Cash” has the meaning assigned to such term in the Partnership Agreement, as in
effect on the 2013 Notes Issue Date.

          “Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under
the Exchange Act, except that, in calculating the beneficial ownership of any particular “person”
(as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to
have beneficial ownership of all securities that such “person” has the right to acquire by
conversion or exercise of other securities, whether such right is currently exercisable or is
exercisable only after the passage of time. The terms “Beneficially Owns” and “Beneficially Owned”
have a corresponding meaning.

          “Board of Directors” means:

     (1) with respect to a corporation, the board of directors of the corporation or any
committee thereof duly authorized to act on behalf of such board;

     (2) with respect to a partnership, the board of directors or board of managers of the
general partner of the partnership or, if such general partner is itself a limited
partnership, then the board of directors or board of managers of its general partner;

     (3) with respect to a limited liability company, the managing member or members or any
controlling committee of managing members thereof; and

     (4) with respect to any other Person, the board or committee of such Person serving a
similar function.

          “Capital Lease Obligation” means, at the time any determination is to be made, the amount of
the liability in respect of a capital lease that would at that time be required to be capitalized
on a balance sheet prepared in accordance with GAAP.

          “Capital Stock” means:

     (1) in the case of a corporation, corporate stock;

-4-

 

     (2) in the case of an association or business entity, any and all shares, interests,
participations, rights or other equivalents (however designated) of corporate stock;

     (3) in the case of a partnership or limited liability company, partnership interests
(whether general or limited) or membership interests; and

     (4) any other interest or participation that confers on a Person the right to receive a
share of the profits and losses of, or distributions of assets of, the issuing Person,

     but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether
or not such debt securities include any right of participation with Capital Stock.

          “Cash Equivalents” means:

     (1) United States dollars or, in an amount up to the amount necessary or appropriate to
fund local operating expenses, other currencies;

     (2) securities issued or directly and fully guaranteed or insured by the United States

Certificate requesting that the Trustee give such notice and setting forth the information to be
stated in such notice as provided in the preceding paragraph. Such Officers’ Certificate may be
combined with the Officers’ Certificate referred to in Section 3.01.

	Section 3.04 Effect of Notice of Redemption.

          Once notice of redemption is delivered in accordance with Section 3.03 hereof, Notes called
for redemption become irrevocably due and payable on the redemption date at the redemption price.
A notice of redemption may not be conditional.

	Section 3.05 Deposit of Redemption or Purchase Price.

          By 11:00 a.m. Eastern Time on the redemption or purchase date, the Issuers will deposit with
the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of
and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the
Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying
Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of,
and accrued interest on, all Notes to be redeemed or purchased.

          If the Issuers comply with the provisions of the preceding paragraph, on and after the
redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes
called for redemption or surrendered for purchase. If a Note is redeemed or purchased on or after
an interest record date but on or prior to the related interest payment date, then any accrued and
unpaid interest shall be paid to the Person in whose name such Note was registered at the close of
business on such record date. If any Note called for redemption or surrendered for purchase is not
so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply
with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption
or purchase date until such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

	Section 3.06 Notes Redeemed or Purchased in Part.

          Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and,
upon receipt of a Company Order, the Trustee will authenticate for the Holder at the expense of the
Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

	Section 3.07 Optional Redemption.

          (a) At any time prior to July 15, 2014, the Issuers may on any one or more occasions redeem up
to 35% of the aggregate principal amount of Notes (including any Additional Notes) then
Outstanding, upon not less than 10 nor more than 60 days’ notice, at a redemption price of
106.500% of the principal amount thereof, plus accrued and unpaid interest to the Redemption Date
(subject to the right of Holders of record on the relevant record date to receive interest due on
an interest payment date that is on or prior to the Redemption Date), with the net cash proceeds of
one or more Equity Offerings by Regency Energy Partners; provided that:

-26-

 

     (1) at least 65% of the aggregate principal amount of Notes issued on the date of this
Indenture (excluding Notes held by Regency Energy Partners and its Subsidiaries) remains
Outstanding immediately after the occurrence of such redemption; and

     (2) the redemption occurs within 90 days of the date of the closing of such Equity
Offering.

          (b) Except pursuant to the preceding paragraph and paragraph (d) of this Section 3.07 and of
Section 4.15, the Notes will not be redeemable at the Issuers’ option prior to July 15, 2016.

          (c) On or after July 15, 2016, the Issuers may redeem all or a part of the Notes upon not less
than 10 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but
excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on
July 15 of each year indicated below, subject to the rights of Holders of Notes on the relevant
record date to receive interest on an interest payment date that is on or prior to the Redemption
Date:

	 	 	 	 	 
	Year	 	Percentage	 
	2016
	 	 	103.250	%
	2017
	 	 	102.167	%
	2018
	 	 	101.083	%
	2019 and thereafter
	 	 	100.000	%

          Unless the Issuers default in the payment of the redemption price, interest will cease to
accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date.

          (d) At any time prior to July 15, 2016, the Issuers may also redeem all or a part of the
Notes, upon not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to
100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and
unpaid interest to, but excluding, the Redemption Date, subject to the rights of Holders on the
relevant record date to receive interest due on an interest payment date that is on or prior to the
Redemption Date.

          (e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

Section 3.08 [Reserved].

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

          In the event that, pursuant to Section 4.10 hereof, Regency Energy Partners is required to
commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the
procedures specified below.

          The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that
is pari passu with the Notes containing provisions similar to those set forth in this Indenture
with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale
Offer will remain open for a period of at least 20 Business Days following its commencement and not
more than 30 Business Days, except to the extent that a longer period is required by applicable law
(the “Offer Period”). No later than three Business Days after the termination of the Offer Period
(the “Purchase Date”), the

-27-

 

Issuers will apply all Excess Proceeds (the “Offer Amount”) to the
purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or,
if less than the Offer Amount has been tendered,
all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for
any Notes so purchased will be made in the manner prescribed in the Notes.

          If the Purchase Date is on or after an interest record date and on or before the related
interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a
Note is registered at the close of business on such record date, and no additional interest will be
payable to Holders who tender Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Issuers will send, by first class mail, a
notice to the Trustee and each of the Holders. The notice will contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The
notice, which will govern the terms of the Asset Sale Offer, will state:

     (1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section
4.10 hereof and the length of time the Asset Sale Offer will remain open;

     (2) the Offer Amount, the purchase price and the Purchase Date;

     (3) that any Note not tendered or accepted for payment will continue to accrue
interest;

     (4) that, unless the Issuers default in making such payment, any Note accepted for
payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase
Date;

     (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may
elect to have Notes purchased in denominations of $2,000 and integral multiples of $1,000 in
excess thereof only;

     (6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will
be required to surrender the Note, with the form entitled “Option of Holder to Elect
Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the
Issuers, a depositary, if appointed by the Issuers, or a Paying Agent at the address
specified in the notice at least three Business Days before the Purchase Date;

     (7) that Holders will be entitled to withdraw their election if the Issuers, the
Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Note the Holder delivered for purchase and a
statement that such Holder is withdrawing his election to have such Note purchased;

     (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness
surrendered by holders thereof exceeds the Offer Amount, the Issuers will select the Notes
and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal
amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as
may be deemed appropriate by the Issuers so that only Notes in denominations of $2,000 and
integral multiples of $1,000 in excess thereof, will be purchased); and

-28-

 

     (9) that Holders whose Notes were purchased only in part will be issued new Notes equal
in principal amount to the unpurchased portion of the Notes surrendered (or transferred by
book-entry transfer).

          On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on
a pro rata basis to the extent necessary, the Offer Amount allocable to the Notes or portions
thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount allocable to
the Notes has been tendered, all Notes tendered, and will deliver or cause to be delivered to the
Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes
or portions thereof were accepted for payment by the Issuers in accordance with the terms of this
Section 3.09. The Issuers, the Depositary or the Paying Agent, as the case may be, will promptly
(but in any case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Issuers for purchase, and the Issuers will promptly issue a new Note, and the
Trustee, upon receipt of a Company Order, will authenticate and mail or deliver (or cause to be
transferred by book entry) such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or
delivered by the Issuers to the Holder thereof. The Issuers will publicly announce the results of
the Asset Sale Offer on the Purchase Date.

          Other than as specifically provided in this Section 3.09, any purchase pursuant to this
Section 3.09 shall be made pursuant to the provisions of Sections 3.05 and 3.06 hereof.

ARTICLE IV

COVENANTS

          The provisions of Article IV of the Base Indenture are deleted and replaced in their entirety,
solely as they relate to the Notes, by the provisions of this Article IV of this Third Supplemental
Indenture.

Section 4.01 Payment of Notes.

          The Issuers shall pay or cause to be paid the principal of, premium, if any, and interest on
the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and
interest will be considered paid on the date due if the Paying Agent, if other than the Regency
Energy Partners or a Subsidiary thereof, holds as of 11:00 a.m. Eastern Time on the due date money
deposited by the Issuers in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due.

          The Issuers shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, at the then applicable interest rate on
the Notes to the extent lawful; they shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

Section 4.02 Maintenance of Office or Agency.

          The Issuers shall maintain in the continental United States an office or agency (which may be
an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may

-29-

 

be surrendered for registration of transfer or for exchange and where notices and demands to or
upon the Issuers in respect of the Notes and this Indenture may be served. The Issuers shall give
prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Issuers fail to maintain any such required office or agency
or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee.

          The Issuers may also from time to time designate one or more other offices or agencies where
the Notes may be presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or rescission will in any
manner relieve the Issuers of their obligation to maintain an office or agency in the continental
United States for such purposes. The Issuers shall give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such other office or
agency.

          The Issuers hereby designate the Corporate Trust Office of the Trustee as one such office or
agency of the Issuers in accordance with Section 2.05 of the Third Supplemental Indenture.

periods specified in the SEC’s rules and regulations:

10-Q and 10-K if Regency Energy Partners were required to file such reports; and

Regency Energy Partners will file a copy of each of the reports referred to in clauses (a) and (b)
above with the SEC for public availability within the time periods specified in the rules and
regulations applicable to such reports (unless the SEC will not accept such a filing) and will post
the reports on its website within those time periods.

          If, at any time Regency Energy Partners is no longer subject to the periodic reporting
requirements of the Exchange Act for any reason, Regency Energy Partners will nevertheless continue
filing the reports specified in the preceding paragraphs of this Section 4.03 with the SEC within
the time periods specified above unless the SEC will not accept such a filing; provided that, for
so long as Regency Energy Partners is not subject to the periodic reporting requirements of the
Exchange Act for any reason, the time period for filing reports on Form 8-K shall be 5 Business
Days after the event giving rise to the obligation to file such report. Regency Energy Partners
will not take any action for the purpose of causing the SEC not to accept any such filings. If,
notwithstanding the foregoing, the SEC will not accept Regency Energy Partners’ filings for any
reason, Regency Energy Partners will post the reports referred to in the preceding

-30-

 

paragraphs on
its website within the time periods that would apply if Regency Energy Partners were required to
file those reports with the SEC.

Section 4.04 Compliance Certificate.

          (a) The Issuers and each Guarantor (to the extent that such Guarantor is so required under the
TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’

Default has occurred, describing all such Defaults or Events of Default of which he or she may have
knowledge and what action the Issuers are taking or propose to take with respect thereto).

          (b) So long as any of the Notes are Outstanding, the Issuers and the Guarantors will deliver

is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

          The Issuers and each of the Guarantors covenant (to the extent that they may lawfully do so)
that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time
hereafter in force, that may affect the covenants or the performance of this Indenture; and the
Issuers and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly
waive all benefit or advantage of any such law, and covenants that they will not, by resort to any
such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but
shall suffer and permit the execution of every such power as though no such law has been enacted.

paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed
$2.0 million in any calendar year (with unused amounts in any calendar year being carried

Restricted Payment. The Fair Market Value of any assets or securities that are required to be
valued by this Section 4.07 will be determined in the case of amounts over $15.0 million, by the
Board of Directors of the General Partner, whose resolution with respect thereto shall be delivered
to the Trustee. For the purposes of determining compliance with this Section 4.07, if a Restricted
Payment meets the criteria of more than one of the categories of Restricted Payments described in
the preceding clauses (1)-(8), Regency Energy Partners will be permitted to classify (or reclassify
in whole or in part in its sole discretion) such Restricted Payment in any manner that complies
with this Section 4.07.

encumbrance or restriction on the ability of any Restricted Subsidiary to:

restatements, modifications, renewals, supplements, refundings, replacements or refinancings
of those agreements or the Indebtedness to which they relate; provided that the amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings
are not materially more restrictive, taken as a whole, with respect to such dividend,
distribution and other payment restrictions than those contained in those agreements on the
date of this Indenture;

     (2) this Indenture, the Notes and the Note Guarantees;

     (3) applicable law, rule, regulation or order;

     (4) any instrument governing Indebtedness or Equity Interests of a Person acquired by

          (a) Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any
Indebtedness (including Acquired Debt), and Regency Energy Partners will not issue any Disqualified
Equity and will not permit any of its Restricted Subsidiaries to issue any Disqualified Equity;
provided, however, that Regency Energy Partners and any Restricted Subsidiary may incur
Indebtedness (including Acquired Debt) and Regency Energy Partners and the Restricted Subsidiaries
may issue Disqualified Equity, if the Fixed Charge Coverage Ratio for Regency Energy Partners’ most
recently ended four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such
Disqualified Equity is issued, as the case may be, would have been at least 2.0 to 1.0, determined
on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Equity had been issued, as the case
may be, at the beginning of such four-quarter period.

          (b) The provisions of Section 4.09(a) hereof shall not prohibit the incurrence of any of the
following items of Indebtedness (collectively, “Permitted Debt”) or the issuance of any preferred
securities described in clause (11) below:

     (1) the incurrence by Regency Energy Partners and any Restricted Subsidiary of
additional Indebtedness (including any letters of credit) under one or more Credit
Facilities, provided, that, after giving effect to such incurrence, the aggregate principal
amount of all Indebtedness incurred under this clause (1) (with letters of credit being
deemed to have a principal amount

-36-

 

equal to the maximum potential liability of Regency Energy
Partners and its Restricted Subsidiaries thereunder) and then outstanding does not exceed
the greater of (a) $900.0 million and (b) the sum of $500.0 million and 20.0% of Regency
Energy Partners’ Consolidated Net Tangible Assets;

     (2) the incurrence by Regency Energy Partners and its Restricted Subsidiaries of the
Existing Indebtedness;

     (3) the incurrence by Regency Energy Partners, Finance Corp. and the Guarantors of
Indebtedness represented by the Notes and the related Note Guarantees to be issued on the
date of this Indenture;

     (4) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money
obligations, in each case, incurred for the purpose of financing all or any part of the
purchase price or cost of construction or improvement of property, plant or equipment used
in the business of Regency Energy Partners or any of its Restricted Subsidiaries, including
all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to this clause (4), provided that
after giving effect to such incurrence the aggregate principal amount of all Indebtedness
incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a)
$20.0 million and (b) 2.0% of Regency Energy Partners’ Consolidated Net Tangible Assets;

     (5) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to
renew, refund, refinance, replace, defease or discharge, any Indebtedness (other than
intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section
4.09(a) hereof or clauses (2) or (3) of this Section 4.09(b) or this clause (5);

     (6) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among Regency Energy Partners and any of its Restricted
Subsidiaries; provided, however, that:

     (A) if Regency Energy Partners or any Guarantor is the obligor on such Indebtedness and
the payee is not Regency Energy Partners or a Guarantor, such Indebtedness must be expressly
subordinated to the prior payment in full in cash of all Obligations then due with respect
to the Notes, in the case of Regency Energy Partners, or the Note Guarantee, in the case of
a Guarantor, and

     (B) (1) any subsequent issuance or transfer of Equity Interests that results in any
such Indebtedness being held by a Person other than Regency Energy Partners or a Restricted
Subsidiary of Regency Energy Partners and (2) any sale or other transfer of any such
Indebtedness to a Person that is not either Regency Energy Partners or a Restricted
Subsidiary of Regency Energy Partners, will be deemed, in each case, to constitute an
incurrence of such Indebtedness by Regency Energy Partners or such Restricted Subsidiary, as
the case may be, that was not permitted by this clause (6);

     (7) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
Hedging Obligations;

-37-

 

     (8) the guarantee by Regency Energy Partners or any of its Restricted Subsidiaries of
Indebtedness of Regency Energy Partners or a Restricted Subsidiary of Regency Energy
Partners that was permitted to be incurred by another provision of this Section 4.09;
provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the
Notes, then the Guarantee shall be subordinated or pari passu, as applicable, to the same
extent as the Indebtedness guaranteed;

     (9) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
obligations relating to net gas balancing positions arising in the ordinary course of
business and consistent with past practice;

     (10) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
Acquired Debt in connection with a transaction meeting either one of the financial tests set
forth in clause (4) under Section 10.01(a) hereof;

     (11) the issuance by any of Regency Energy Partners’ Restricted Subsidiaries to Regency
Energy Partners or to any of its Restricted Subsidiaries of any preferred securities;
provided, however, that:

     (a) any subsequent issuance or transfer of Equity Interests that results in any
such preferred securities being held by a Person other than Regency Energy Partners
or a Restricted Subsidiary of Regency Energy Partners; and

     (b) any sale or other transfer of any such preferred securities to a Person
that is not either Regency Energy Partners or a Restricted Subsidiary of Regency
Energy Partners

will be deemed, in each case, to constitute an issuance of such preferred securities by such
Restricted Subsidiary that was not permitted by this clause (11); and

     (12) the incurrence by Regency Energy Partners or any of its Restricted Subsidiaries of
additional Indebtedness; provided that, after giving effect to any such incurrence, the
aggregate principal amount of all Indebtedness incurred under this clause (12) and then
outstanding does not exceed the greater of (a) $25.0 million and (b) 2.5% of Regency Energy
Partners’ Consolidated Net Tangible Assets.

          Regency Energy Partners shall not incur, and shall not permit Finance Corp. or any Guarantor
to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right
of payment to any other Indebtedness of Regency Energy Partners, Finance Corp. or such Guarantor
unless such Indebtedness is also contractually subordinated in right of payment to the Notes and
the applicable Note Guarantee on substantially identical terms; provided, however, that no
Indebtedness of a Person shall be deemed to be contractually subordinated in right of payment to
any other Indebtedness of such Person solely by virtue of being unsecured or by virtue of being
secured on a first or junior Lien basis.

          For purposes of determining compliance with this Section 4.09, if an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in
clauses (1) through (12) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof,
Regency Energy Partners will be permitted to classify such item of Indebtedness on the date of its
incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that
complies with this Section 4.09. Indeb-

-38-

 

tedness under Credit Facilities outstanding on the date on
which Notes are first issued and authenticated under this Indenture will initially be deemed to
have been incurred on such date in reliance on the exception provided by clause (1) of the
definition of Permitted Debt.

          The accrual of interest, the accretion or amortization of original issue discount, the payment
of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the
reclassification of preferred stock as Indebtedness due to a change in accounting principles, and
the payment of dividends on Disqualified Equity in the form of additional shares of the same class
of Disqualified Equity will not be deemed to be an incurrence of Indebtedness or an issuance of
Disqualified Equity for purposes of this Section 4.09; provided, however, in each such case, that
the amount of any such accrual, accretion or payment is included in Fixed Charges of Regency Energy
Partners as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount
of Indebtedness that Regency Energy Partners or any Restricted Subsidiary may incur pursuant to
this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange
rates or currency values.

Section 4.10 Asset Sales.

          Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

     (1) Regency Energy Partners (or the Restricted Subsidiary, as the case may be) receives
consideration at the time of the Asset Sale at least equal to the Fair Market Value of the
assets or Equity Interests issued or sold or otherwise disposed of;

     (2) such Fair Market Value is determined by the Board of Directors of the General
Partner if the value is $15.0 million or more, as evidenced by a resolution of such Board of
Directors of the General Partner; and

     (3) at least 75% of the aggregate consideration received by Regency Energy Partners and
its Restricted Subsidiaries in the Asset Sale and all other Asset Sales since the 2013 Notes
Issue Date is in the form of cash or Cash Equivalents. For purposes of this provision, each
of the following shall be deemed to be cash:

     (A) any liabilities, as shown on Regency Energy Partners’ most recent consolidated
balance sheet, of Regency Energy Partners or any Restricted Subsidiary (other than
contingent liabilities and liabilities that are by their terms subordinated to the Notes or
any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases Regency Energy Partners or such Restricted
Subsidiary from further liability; and

     (B) any securities, notes or other obligations received by Regency Energy Partners or
any such Restricted Subsidiary from such transferee that are within 90 days after the Asset
Sale (subject to ordinary settlement periods), converted by Regency Energy Partners or such
Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash
Equivalents received in that conversion.

-39-

 

          Within 365 days after the receipt of any Net Proceeds from an Asset Sale (or within 180 days
after such 365-day period in the event Regency Energy Partners enters into a binding commitment
with respect to such application), Regency Energy Partners (or the applicable Restricted
Subsidiary, as the case may be) may apply such Net Proceeds:

     (1) to repay Senior Indebtedness of Regency Energy Partners and/or its Restricted
Subsidiaries (or to make an offer to repurchase or redeem such Indebtedness, provided that
such repurchase or redemption closes within 45 days after the end of such 365-day period)
with a permanent reduction in availability for any revolving credit Indebtedness;

     (2) to acquire all or substantially all of the assets of, or any Capital Stock of,
another Permitted Business, if, after giving effect to any such acquisition of Capital
Stock, the Permitted Business is or becomes a Restricted Subsidiary of Regency Energy
Partners;

     (3) to make a capital expenditure; or

     (4) to acquire other assets that are not classified as current assets under GAAP and
that are used or useful in a Permitted Business.

Pending the final application of any Net Proceeds, Regency Energy Partners or the applicable
Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the
Net Proceeds in any manner that is not prohibited by this Indenture.

          Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second
paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of
Excess Proceeds exceeds $20.0 million, within five days thereof, Regency Energy Partners will make
an Asset Sale Offer, pursuant to Section 3.09, to all Holders of Notes (and deliver a copy thereof
to the Trustee) and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers to purchase or
redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and
such other pari passu Indebtedness that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be
equal to 100% of the principal amount of the Notes plus accrued and unpaid interest to, but
excluding, the date of purchase, subject to the rights of Holders of Notes on the relevant record
date to receive interest due on an interest payment date that is on or prior to the purchase date,
and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale
Offer, Regency Energy Partners may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, then the
Notes and such other pari passu Indebtedness shall be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Issuers so that only Notes and such other pari
passu Indebtedness will be purchased in an authorized denomination and integral multiples thereof).
Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

          In making an Asset Sale Offer Regency Energy Partners will comply with the applicable
requirements of Rule 14e-1 under the Exchange Act and other securities laws and regulations. To
the extent that the provisions of any securities laws or regulations conflict with the provisions
of Section 3.09 hereof or this Section 4.10, Regency Energy Partners will comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations
under Section 3.09 hereof or this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

          (a) Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries
to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or
assets to, or purchase any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of Regency Energy Partners (each an “Affiliate Transaction”), unless:

     (1) the Affiliate Transaction is on terms that are no less favorable to Regency Energy
Partners or the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by Regency Energy Partners or such Restricted Subsidiary with an
unrelated Person; and

     (2) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $50.0 million, Regency Energy
Partners delivers to the Trustee a resolution of the Board of Directors of the General
Partner set forth in an Officers’ Certificate certifying that such Affiliate Transaction or
series of related Affiliate Transactions complies with clause (1) of this Section 4.11(a)
and that such Affiliate Transaction has been approved by a majority of the disinterested
members of the Board of Directors of Regency Energy Partners.

          (b) The following items will not be deemed to be Affiliate Transactions and, therefore, shall
not be subject to the provisions of Section 4.11(a) hereof:

     (1) any employment agreement, equity award, equity option or equity appreciation
agreement or plan or any similar arrangement entered into by Regency Energy Partners or any
of its Restricted Subsidiaries in the ordinary course of business and payments pursuant
thereto;

     (2) transactions between or among Regency Energy Partners and/or its Restricted
Subsidiaries;

     (3) transactions with a Person (other than an Unrestricted Subsidiary of Regency Energy
Partners) that is an Affiliate of Regency Energy Partners solely because Regency Energy
Partners owns, directly or through a Restricted Subsidiary, an Equity Interest in, or
controls, such Person;

     (4) any issuance of Equity Interests (other than Disqualified Equity) of Regency Energy
Partners to Affiliates of Regency Energy Partners;

     (5) Restricted Payments or Permitted Investments that do not violate Section 4.07
hereof;

     (6) customary compensation, indemnification and other benefits made available to
officers, directors or employees of Regency Energy Partners, a Restricted Subsidiary of
Regency Energy Partners or the General Partner, including reimbursement or advancement of
out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

     (7) in the case of contracts for purchase, gathering, processing, sale, transportation
and marketing of crude oil, natural gas, condensate and natural gas liquids, hedging
agreements,

-41-

 

and production handling, operating, construction, terminaling, storage, lease,
platform use, or other operational contracts, any such contracts are entered into in the
ordinary course of business on terms substantially similar to those contained in similar
contracts entered into by Regency Energy Partners or any Restricted Subsidiary and third
parties, or if neither Regency Energy Partners nor any Restricted Subsidiary has entered
into a similar contract with a third party, that the terms are no less favorable than those
available from third parties on an arm’s length basis, as determined by the Board of
Directors of the General Partner;

     (8) loans or advances to employees in the ordinary course of business not to exceed
$1.0 million in the aggregate at any one time outstanding; and

     (9) transactions effected in accordance with the terms of (a) the Contribution
Agreement, the Partnership Agreement, the Master Services Agreement or the AMI Agreement, as
the case may be, referred to in the Current Report on Form 8-K of Regency Energy Partners
filed with the SEC on March 18, 2009, (b) the Contribution Agreement dated as of May 10,
2010 by and among Energy Transfer Equity, L.P., Regency Energy Partners and Regency
Midcontinent Express LLC, (c) the Amended and Restated Limited Liability Company Agreement
dated as of March 1, 2007 of MEP, (d) the Amended and Restated Limited Liability Company

dated as of May 19, 2011 by and between La Grange Acquisition, L.P. d/b/a Energy Transfer
Company, Regency GP LP, Regency Energy Partners LP and Regency Gas Services LP, as each such
agreement described in clauses (a) through (e) is in effect on the date of this Indenture,
and any amendment or extension of such agreement so long as the terms of such amendment or
extension, taken as a whole, are not less advantageous to Regency Energy Partners or the
relevant Restricted Subsidiary (as determined by the Board of Directors of the General
Partner in its reasonable good faith judgment) in any material respect than the agreement so
amended or extended.

Section 4.12 Liens.

          Regency Energy Partners will not, and will not permit any of its Restricted Subsidiaries to,
create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any
kind (other than Permitted Liens) securing Indebtedness (including any Attributable Debt) upon any
of their property or assets, now owned or hereafter acquired, unless all payments due under the
Notes are secured
on an equal and ratable basis or on a senior basis with obligations so secured until such time
as such obligations are no longer secured by a Lien (other than Permitted Liens).

Section 4.13 Business Activities.

          Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries to,
engage in any business other than Permitted Businesses, except to such extent as would not be
material to Regency Energy Partners and its Restricted Subsidiaries taken as a whole.

          Finance Corp. shall not hold any material assets, become liable for any material obligations
or engage in any significant business activities; provided, that Finance Corp. may be a co-obligor
or guarantor with respect to Indebtedness if Regency Energy Partners is an obligor on such
Indebtedness and the net proceeds of such Indebtedness are received by Regency Energy Partners,
Finance Corp. or one or more Guarantors. At any time after Regency Energy Partners is a
corporation, Finance Corp. may consolidate or merge with or into Regency Energy Partners or any
Restricted Subsidiary.

-42-

 

Section 4.14 Corporate Existence.

          Subject to Article X hereof, Regency Energy Partners shall do or cause to be done all things
necessary to preserve and keep in full force and effect:

     (1) its limited partnership existence, and the corporate, partnership or other
existence of each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of Regency Energy
Partners or any such Restricted Subsidiary; and

     (2) the rights (charter and statutory), licenses and franchises of Regency Energy
Partners and its Restricted Subsidiaries;

provided, however, that Regency Energy Partners shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other existence of any of its Restricted
Subsidiaries, if it shall determine that the preservation thereof is no longer desirable in the
conduct of the business of Regency Energy Partners and its Restricted Subsidiaries, taken as a
whole, and that the loss thereof is not adverse in any material respect to the Holders of the
Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

          (a) Upon the occurrence of a Change of Control, Regency Energy Partners shall make an offer (a
“Change of Control Offer”) to each Holder of Notes to repurchase all or any part (equal to $2,000
or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in
cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid
interest on the Notes repurchased to, but excluding, the date of purchase, subject to the rights of
Holders of Notes on the relevant record date to receive interest due on an interest payment date
that is prior to the purchase date (the “Change of Control Payment”). Within 30 days following any
Change of Control, Regency Energy Partners will mail a notice to the Trustee and each Holder
describing the transaction or transactions that constitute the Change of Control and stating:

     (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and
that all Notes tendered will be accepted for payment;

     (2) the purchase price and the purchase date, which shall be no earlier than 20
Business Days and no later than 60 days from the date such notice is mailed (the “Change of
Control Payment Date”);

     (3) that any Note not tendered will continue to accrue interest;

     (4) that, unless Regency Energy Partners defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will
cease to accrue interest after the Change of Control Payment Date;

     (5) that Holders electing to have any Notes purchased pursuant to a Change of Control
Offer will be required to surrender the Notes, with the form entitled “Option of Holder to
Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the
Paying Agent at the address specified in the notice prior to the close of business on the
third Business Day preceding the Change of Control Payment Date;

-43-

 

     (6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day preceding the
Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of Notes delivered for purchase, and a
statement that such Holder is withdrawing his election to have the Notes purchased; and

     (7) that Holders whose Notes are being purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered, which
unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of
$1,000 in excess thereof.

          Regency Energy Partners shall comply with all applicable requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations. To the extent that the provisions of
any securities laws or regulations conflict with the provisions of this Section 4.15, Regency
Energy Partners shall comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

          (b) On the Change of Control Payment Date, Regency Energy Partners shall, to the extent
lawful:

     (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the
Change of Control Offer;

     (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions of Notes properly tendered; and

     (3) deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officers’ Certificate stating the aggregate principal amount of Notes or
portions of Notes being purchased by the Issuers.

          The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of
Control Payment for such Notes (or, to the extent the Notes are in global form, make such payment
through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered; provided, that each new Note will be in a principal amount of
$2,000 or
an integral multiple of $1,000 in excess thereof. Regency Energy Partners will publicly
announce the results of the Change of Control Offer on or as soon as practicable after the Change
of Control Payment Date.

          The provisions described above that require the Issuers to make a Change of Control Offer
following a Change of Control will be applicable whether or not any other provisions of this
Indenture are applicable.

          (c) Notwithstanding anything to the contrary in this Section 4.15, Regency Energy Partners
will not be required to make a Change of Control Offer upon a Change of Control if (1) a third
party makes the Change of Control Offer in the manner, at the times and otherwise in compliance
with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and
not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given
pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable
redemption price. Notwithstanding

-44-

 

anything to the contrary contained in this Indenture, a Change
of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation
of such Change of Control, if a definitive agreement is in place for the Change of Control at the
time the Change of Control Offer is made.

          (d) In the event that Holders of not less than 90% of the aggregate principal amount of the
Outstanding Notes accept a Change of Control Offer and Regency Energy Partners purchases all of the
Notes held by such Holders, Regency Energy Partners will have the right, upon not less than 15 nor
more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the
Change of Control Offer described above, to redeem all of the Notes that remain Outstanding
following such purchase at a redemption price equal to 101% of the aggregate principal amount of
Notes redeemed plus accrued and unpaid interest thereon to, but excluding, the date of redemption,
subject to the right of the Holders of Notes on the relevant record date to receive interest due on
an interest payment date that is on or prior to the Redemption Date.

Section 4.16 Limitation on Sale and Leaseback Transactions.

          Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries to,
enter into any sale and leaseback transaction; provided that Regency Energy Partners or any
Restricted Subsidiary may enter into a sale and leaseback transaction if the transfer of assets in
that sale and leaseback transaction is permitted by, and Regency Energy Partners or such Restricted
Subsidiary applies the proceeds of such transaction in compliance with, Section 4.10 hereof.

Section 4.17 Payments for Consent.

          Regency Energy Partners shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any
Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Notes unless such consideration is offered to be paid and is
paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement.

Section 4.18 Additional Guarantees.

          If, after the date of this Indenture, any Restricted Subsidiary of Regency Energy Partners
that is not already a Guarantor guarantees any Indebtedness of either of the Issuers or any
Indebtedness of any Guarantor, or any Domestic Subsidiary, if not then a Guarantor, incurs any
Indebtedness under any Credit Facility, then in either case that Subsidiary will become a Guarantor
by executing a supplemental
indenture substantially in the form of Exhibit C to the Third Supplemental Indenture and
delivering it to the Trustee within 20 Business Days of the date on which it guaranteed or incurred
such Indebtedness, as the case may be; provided, however, that the preceding shall not apply to
Subsidiaries of Regency Energy Partners that have been properly designated as Unrestricted
Subsidiaries in accordance with this Indenture for so long as they continue to constitute
Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Restricted
Subsidiary that was incurred pursuant to this paragraph as a result of its guarantee of any
Indebtedness shall provide by its terms that it shall be automatically and unconditionally released
upon the release or discharge of the Guarantee that resulted in the creation of such Restricted
Subsidiary’s Note Guarantee, except a discharge or release by, or as a result of payment under,
such Guarantee.

Section 4.19 Designation of Restricted and Unrestricted Subsidiaries.

          The Board of Directors of the General Partner may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary
is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding
Investments owned by Regency Energy Partners and its Restricted Subsidiaries in the Subsidiary
designated as Unrestricted will be deemed to be either an Investment made as of the time of the
designation that will reduce the amount available for Restricted Payments under Section 4.07 hereof
or a Permitted Investment under one or more clauses of the definition of Permitted Investments, as
determined by Regency Energy Partners; provided that any designation will only be permitted if the
Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.

          Any designation of a Subsidiary of Regency Energy Partners as an Unrestricted Subsidiary will
be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the
Board of Directors of the General Partner giving effect to such designation and an Officers’
Certificate certifying that such designation complied with the preceding conditions and was
permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet
the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will
be deemed to be incurred by a Restricted Subsidiary of Regency Energy Partners as of such date and,
if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof,
Regency Energy Partners will be in default of such covenant. The Board of Directors of the General
Partner may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of
Regency Energy Partners; provided that such designation will be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of Regency Energy Partners of any outstanding Indebtedness
of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such
Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such
designation had occurred at the beginning of the four-quarter reference period; and (2) no Default
or Event of Default would be in existence following such designation.

Section 4.20 Termination of Covenants.

          If at any time the Notes achieve an Investment Grade Rating from both of the Rating Agencies
and no Default or Event of Default has occurred and is then continuing under this Indenture,
Regency Energy Partners and its Restricted Subsidiaries will no longer be subject to the following
provisions of this Indenture:

     (1) Section 4.07;

     (2) Section 4.08;

     (3) Section 4.09;

     (4) Section 4.10;

     (5) Section 4.11;

     (6) Section 4.13;

     (7) Section 4.16;

-46-

 

     (8) Section 4.18;

     (9) Section 4.19; and

     (10) Section 10.01(a)(4).

          Promptly after such termination, Regency Energy Partners shall deliver to the Trustee an
Officers’ Certificate certifying to such termination.

10.01 hereof, the successor Person formed by such consolidation or into or with which Regency
Energy Partners is merged or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and after the date of
such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the
provisions of this Indenture referring to “Regency Energy Partners” shall refer instead to the

ARTICLE VI

DEFAULTS AND REMEDIES

          The provisions of Article VI of the Base Indenture are deleted and replaced in their entirety,
solely as they relate to the Notes, by the provisions of this Article VI of this Third Supplemental
Indenture.

	Section 6.01 Events of Default.

          Each of the following is an “Event of Default”:

     (1) default for 30 days in the payment when due of interest on the Notes;

Regency Energy Partners or any of its Restricted Subsidiaries (or the payment of which
is guaranteed by Regency Energy Partners or any of its Restricted Subsidiaries), whether
such Indebtedness or Guarantee now exists, or is created after the date of this Indenture,
if that default:

     (A) is caused by a failure to pay principal of, or interest or premium, if any, on
Indebtedness prior to the expiration of the grace period provided in such Indebtedness on
the date of such default (a “Payment Default”); or

-49-

 

     (B) results in the acceleration of such Indebtedness prior to its express
maturity,

and, in each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a Payment Default
or the maturity of which has been so accelerated, aggregates $20.0 million or more,
provided, however, that if, prior to any acceleration of the Notes, (i) any such Payment
Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such
Indebtedness is repaid during the 10 Business Day period commencing upon the end of any
applicable grace period for such Payment Default or the occurrence of such acceleration, as
applicable, any Default or Event of Default (but not any acceleration of the Notes) caused
by such Payment Default or acceleration shall automatically be rescinded, so long as such
rescission does not conflict with any judgment, decree or applicable law;

     (7) failure by an Issuer or any of Regency Energy Partners’ Restricted Subsidiaries to
pay final judgments entered by a court or courts of competent jurisdiction aggregating in
excess of $20.0 million, which judgments are not paid, discharged or stayed for a period of

     (8) an Issuer or any of Regency Energy Partners’ Restricted Subsidiaries that is a

     (A) commences a voluntary case,

     (B) consents to the entry of an order for relief against it in an involuntary case,

     (C) consents to the appointment of a custodian of it or for all or substantially all of
its property,

     (D) makes a general assignment for the benefit of its creditors, or

     (E) generally is not paying its debts as they become due;

     (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that:

Regency Energy Partners that, taken together, would constitute a Significant Subsidiary or

Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries of Regency Energy Partners that, taken together, would constitute a Significant
Subsidiary; or

-50-

 

     (C) orders the liquidation of an Issuer or any of Regency Energy Partners’ Restricted
Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of
Regency Energy Partners that, taken together, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days; and

     (10) except as permitted by this Indenture, any Note Guarantee is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and
effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or
disaffirms its Obligations under its Note Guarantee.

Section 6.02 Acceleration.

          In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, with
respect to Finance Corp., Regency Energy Partners or any Restricted Subsidiary of Regency Energy
Partners that is a Significant Subsidiary or any group of Restricted Subsidiaries of Regency Energy
Partners that, taken together, would constitute a Significant Subsidiary, all Outstanding Notes
will become due and payable immediately without further action or notice. If any other Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then Outstanding Notes may declare, by notice in writing to the Issuers, all the
Notes to be due and payable immediately.

          Upon any such declaration, the Notes shall become due and payable immediately.

          The Holders of at least a majority in aggregate principal amount of the then Outstanding Notes
by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration
or waive any existing Default or Event of Default and its consequences under this Indenture except
a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the
principal of, the Notes.

Section 6.03 Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy
to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of the then Outstanding
Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing
Default or Event of Default and its consequences hereunder, except a continuing Default or Event of
Default in the payment of the principal of, premium, if any, or interest on, the Notes (including
in connection with an offer to purchase); provided, however, that the Holders of a majority in
aggregate principal amount of the

-51-

 

then Outstanding Notes may rescind an acceleration and its
consequences, including any related payment default that resulted from such acceleration. Upon any
such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be
deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

          Holders of at least a majority in aggregate principal amount of the then Outstanding Notes may
direct the time, method and place of conducting any proceeding for exercising any remedy available
to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture that the Trustee determines may
be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in
personal liability.

Section 6.06 Limitation on Suits.

          A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

     (1) such Holder gives to the Trustee written notice that an Event of Default is
continuing;

     (2) Holders of at least 25% in aggregate principal amount of the then Outstanding Notes
make a written request to the Trustee to pursue the remedy;

     (3) such Holder or Holders offer and, if requested, provide to the Trustee security or
indemnity satisfactory to the Trustee in its sole discretion against any loss, liability or
expense;

     (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of security or indemnity; and

     (5) during such 60-day period, Holders of at least a majority in aggregate principal
amount of the then Outstanding Notes do not give the Trustee a direction inconsistent with
such request.

          A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a
Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to
receive payment of principal, premium, if any, and interest on the Note, on or after the respective
due dates expressed in the Note (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the

-52-

 

Issuers for the whole amount of principal of, premium, if any, and interest remaining
unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel.

Section 6.09 Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers
(or any other obligor upon the Notes), their creditors or their property and shall be entitled and
empowered to collect, receive and distribute any money or other property payable or deliverable on
any such claims and any custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder
in any such proceeding.

Section 6.10 Priorities.

          If the Trustee collects any money or property pursuant to this Article VI, it shall pay out
the money or property in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under Section 7.06
hereof, including payment of all compensation, expenses and liabilities incurred, and all
advances made, by the Trustee and the costs and expenses of collection;

     Second: to Holders of Notes for amounts due and unpaid on the Notes for principal,
premium, if any, and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for principal, premium, if any, and
interest, respectively; and

     Third: to the Issuers or to such party as a court of competent jurisdiction shall
direct.

          The Trustee may fix a record date and payment date for any payment to Holders of Notes
pursuant to this Section 6.10.

-53-

 

Section 6.11 Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by a Holder of a Note pursuant to
Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of
the then Outstanding Notes.

Section 6.12 Willful Action or Inaction.

          In the case of any Event of Default occurring by reason of any willful action or inaction
taken or not taken by or on behalf of an Issuer with the intention of avoiding payment of the
premium that the Issuers would have had to pay if the Issuers then had elected to redeem the Notes
on or after July 15, 2016 pursuant to Section 3.07, an equivalent premium will also become and be
immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If
an Event of Default occurs prior to July 15, 2016 by reason of any willful action or inaction taken
or not taken by or on behalf of an Issuer with the intention of avoiding the prohibition on
redemption of the Notes prior to that date, then the applicable redemption price pursuant to
Section 3.07 with respect to the first year that the Notes may be redeemed at the Issuers’ option
(other than with the net cash proceeds of an Equity Offering or on a make-whole basis) will also
become immediately due and payable to the extent permitted by law upon the acceleration of the
Notes.

contained in Sections 3.09, 4.03, 4.04 (except for paragraph (a) thereof to the extent required by
the TIA), 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18 and 4.19 hereof
and clause (4) of Section 10.01 hereof with respect to the Outstanding Notes, and the Guarantors
will be released from their obligations with respect to the Note Guarantees, on and after the date
the conditions set forth in Section 11.04 hereof are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes will thereafter be deemed not “Outstanding” for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof)
in connection with such covenants, but will continue to be deemed “Outstanding” for all other
purposes hereunder (it being understood that such Notes will not be deemed Outstanding for
accounting purposes to the extent permitted by GAAP). For this purpose, Covenant Defeasance means
that, with respect to the Outstanding Notes and Note Guarantees, the Issuers and the Guarantors may
omit to comply with and will have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply will not constitute a Default
or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of
this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon
the Issuers’ exercise under Section 11.01 hereof of the option applicable to this Section 11.03,
subject to the satisfaction of the conditions set forth in Section 11.04 hereof, Sections 6.01(3)
through 6.01(7) inclusive hereof will not constitute Events of Default.

Section 11.04 Conditions to Legal or Covenant Defeasance.

          In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 11.02
or 11.03 hereof:

     (1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a
combination of cash in U.S. dollars and non-callable Government Securities, in amounts as
will be suffi-

-56-

 

cient, in the opinion of a nationally recognized investment bank, appraisal
firm or firm of independent public accountants, to pay the principal of, or interest and
premium, if any, on the Outstanding Notes on the stated date for payment thereof or on the
applicable Redemption Date, as the case may be, and the Issuers must specify whether the
Notes are being defeased to such stated date for payment or to a particular Redemption Date;

     (2) in the case of an election under Section 11.02 hereof, the Issuers must deliver to
the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

     (A) the Issuers have received from, or there has been published by, the Internal
Revenue Service a ruling; or

     (B) since the date of this Indenture, there has been a change in the applicable federal
income tax law, in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders of the Outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Legal Defeasance had not occurred;

     (3) in the case of an election under Section 11.03 hereof, the Issuers must deliver to
the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the
Holders of the Outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the
case if such Covenant Defeasance had not occurred;

     (4) no Default or Event of Default shall have occurred and be continuing on the date of
such deposit (other than a Default or Event of Default resulting from the borrowing of funds
to be applied to such deposit);

     (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other
than this Indenture) to which Regency Energy Partners or any of its Subsidiaries is a party
or by which Regency Energy Partners or any of its Subsidiaries is bound;

     (6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the
deposit was not made by the Issuers with the intent of preferring the Holders of Notes over
the other creditors of the Issuers with the intent of defeating, hindering, delaying or
defrauding any creditors of the Issuers or others; and

     (7) the Issuers must deliver to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

Section 11.05 Deposited Money and Government Securities to Be Held in Trust; Other
Miscellaneous Provisions.

          Subject to Section 11.06 hereof, all money and non-callable Government Securities (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for
pur-

-57-

 

poses of this Section 11.05, the “Trustee”) pursuant to Section 11.04 hereof in respect of the
Outstanding Notes will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including either Issuer acting as Paying Agent) as the Trustee may determine, to the Holders
of such Notes of all sums due and to become due thereon in respect of principal, premium, if any,
and interest, but such money need not be segregated from other funds except to the extent required
by law.

          The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable Government Securities deposited pursuant to Section
11.04 hereof or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes.

          Notwithstanding anything in this Article XI to the contrary, the Trustee will deliver or pay
to the Issuers from time to time upon the request of the Issuers any money or non-callable
Government Securities held by it as provided in Section 11.04 hereof which, in the opinion of a
nationally recognized investment bank, appraisal firm or firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 11.04(1) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 11.06 Repayment to the Issuers.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in
trust for the payment of the principal of, premium, if any, or interest on, any Note and remaining
unclaimed for two years after such principal, premium, if any, or interest has become due and
payable shall be paid to the Issuers on their request or (if then held by the Issuers) will be
discharged from such trust; and the Holder of such Note will thereafter be permitted to look only
to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Issuers as trustee thereof, will thereupon
cease; provided, however, that, if any Notes then Outstanding are in definitive form, the Trustee
or such Paying Agent, before being required to make any such repayment, may at the expense of the
Issuers cause to be published once, in The New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date specified therein, which
will not be less than 30 days from the date of such notification or publication, any unclaimed
balance of such money then remaining will be repaid to the Issuers.

Section 11.07 Reinstatement.

          If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government
Securities in accordance with Section 11.02 or 11.03 hereof, as the case may be, by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this
Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit
had occurred pursuant to Section 11.02 or 11.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 11.02 or 11.03 hereof, as the
case may be; provided, however, that, if the Issuers make any payment of principal of, premium , if
any, or interest on, any Note following the reinstatement of its obligations, the Issuers will be
subrogated to the rights of the Holders of such Notes to receive such payment from the money held
by the Trustee or Paying Agent.

Section 11.08 Satisfaction and Discharge.

-58-

 

          This Indenture will be discharged and will cease to be of further effect as to all Notes
issued hereunder (except as to surviving rights of transfer or exchange of the Notes and as
otherwise specified herein), when:

          (1) either:

     (a) all Notes that have been authenticated, except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuers, have been
delivered to the Trustee for cancellation; or

     (b) all Notes that have not been delivered to the Trustee for cancellation have
become due and payable or will become due and payable within one year by reason of
the mailing of a notice of redemption or otherwise and the Issuers or any Guarantor
has irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable
Government Securities, or a combination of cash in U.S. dollars and non-callable
Government Securities, in amounts as will be sufficient, without consideration of
any reinvestment of interest, to pay and discharge the entire Indebtedness on the
Notes not delivered to the Trustee for cancellation for principal and premium, if
any, and accrued interest to the date of fixed maturity or redemption;

     (2) no Default or Event of Default has occurred and is continuing on the date of such
deposit (other than a Default or Event of Default resulting from the borrowing of funds to
be applied to such deposit) and the deposit will not result in a breach or violation of, or
constitute a default under, any other instrument to which Regency Energy Partners or any
Guarantor is a party or by which Regency Energy Partners or any Guarantor is bound;

     (3) the Issuers or any Guarantor has paid or caused to be paid all sums payable by it
under this Indenture; and

     (4) the Issuers have delivered irrevocable instructions to the Trustee under this
Indenture to apply the deposited money toward the payment of the Notes at fixed maturity or
on the Redemption Date, as the case may be.

          In addition, the Issuers must deliver an Officers’ Certificate and an Opinion of Counsel to
the Trustee stating that all conditions precedent to satisfaction and discharge have been
satisfied.

          Notwithstanding the satisfaction and discharge of this Indenture, if money or Government
Securities have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this
Section 11.08, the provisions of Sections 2.07, 2.08, 2.09, 11.06 and 11.09 hereof will survive.
In addition, nothing in this Section 11.08 will be deemed to discharge those provisions of Section
7.06 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.09 Application of Trust Money.

          Subject to the provisions of Section 11.06 hereof, all money deposited with the Trustee
pursuant to Section 11.08 hereof shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including

-59-

 

either Issuer acting as Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal, premium, if any, and interest for whose payment such money has
been deposited with the Trustee; but such money need not be segregated from other funds except to
the extent required by law.

          If the Trustee or Paying Agent is unable to apply any money or Government Securities in
accordance with Section 11.08 hereof by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes
shall be revived
and reinstated as though no deposit had occurred pursuant to Section 11.08 hereof, provided
that if the Issuers have made any payment of principal of, premium, if any, or interest on, any
Notes because of the reinstatement of its obligations, the Issuers shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money or Government Securities
held by the Trustee or Paying Agent.

ARTICLE IX

AMENDMENT, SUPPLEMENT AND WAIVER

          The provisions of Article IX of the Base Indenture are deleted and replaced in their entirety,
solely as they relate to the Notes, by the provisions of this Article IX of this Third Supplemental
Indenture.

Section 9.01 Without Consent of Holders of Notes.

          Notwithstanding Section 9.02 of this Indenture, the Issuers, the Guarantors and the Trustee
may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of
any Holder of Notes:

     (1) to cure any ambiguity, defect or inconsistency;

     (2) to provide for uncertificated Notes in addition to or in place of certificated
Notes;

     (3) to provide for the assumption of the Issuers’ or a Guarantor’s obligations to the
Holders of the Notes and Note Guarantees in the case of a merger or consolidation or sale of
all or substantially all of the Issuers’ or such Guarantors’ properties or assets, as
applicable;

     (4) to make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights hereunder of any
such Holder;

     (5) to comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA;

     (6) to conform the text of this Indenture or the Note Guarantees to any provision of
the “Description of the Notes” section of the Issuers’ prospectus supplement dated May 26,
2011 (the “Prospectus Supplement”) to the base prospectus included in the Issuers’
registration statement on Form S-3 (File No. 333-169901) relating to the issuance and sale
of the Initial Notes, to

-60-

 

the extent that such text of this Indenture or the Note Guarantees
was intended to reflect such provision of the “Description of the Notes”;

     (7) to provide for the issuance of Additional Notes in accordance with the limitations
set forth in this Indenture as of the date hereof;

     (8) to allow any Guarantor to execute a supplemental indenture and/or a notation of
Note Guarantee with respect to the Notes or to reflect the addition or release of a Note
Guarantee in accordance with this Indenture;

     (9) to secure the Notes and/or the Note Guarantees; or

     (10) to provide for the reorganization of Regency Energy Partners as any other form of
entity, in accordance with Section 10.01(b) hereof.

          Upon the request of the Issuers accompanied by resolutions of their Boards of Directors
authorizing the execution of any such amended or supplemental indenture, and upon receipt by the
Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Issuers
and the Guarantors in the execution of any amended or supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not be obligated to enter into
such amended or supplemental indenture that affects its own rights, duties or immunities under this
Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may
amend or supplement this Indenture (including Sections 3.09, 4.10 and 4.15 hereof) and the Notes
and the Note Guarantees with the consent of the Holders of at least a majority in aggregate
principal amount of the then Outstanding Notes (including Additional Notes, if any) voting as a
single class (including, without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any
existing Default or Event of Default or compliance with any provision of this Indenture or the
Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in
aggregate principal amount of the then Outstanding Notes (including, without limitation, Additional
Notes, if any) voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes).

          Upon the request of the Issuers accompanied by resolutions of their Boards of Directors
authorizing the execution of any such amended or supplemental indenture, and upon the filing with
the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the
Trustee will join with the Issuers and the Guarantors in the execution of such amended or
supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may
in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

          It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve
the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such
consent approves the substance thereof.

-61-

 

          After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Issuers will mail to the Holders of Notes affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect
therein, will not, however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver.

          However, without the consent of each Holder affected, an amendment, supplement or waiver under
this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

     (1) reduce the principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver;

     (2) reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to the redemption or repurchase of the Notes (other than provisions
relating to Sections 3.09, 4.10 or 4.15 hereof);

     (3) reduce the rate of or change the time for payment of interest, including default
interest, on any Note;

     (4) waive a Default or Event of Default in the payment of principal, premium, if any,
or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of
at least a majority in aggregate principal amount of the then Outstanding Notes and a waiver
of the payment default that resulted from such acceleration);

     (5) make any Note payable in money other than that stated in the Notes;

     (6) make any change in the provisions of this Indenture relating to waivers of past
Defaults or the rights of Holders of Notes to receive payments of principal of, or interest
or premium, if any, on, the Notes (other than as permitted by clause (7) below);

     (7) waive a redemption or repurchase payment with respect to any Note (other than a
payment required by Sections 4.10 or 4.15 hereof);

     (8) release any Guarantor from any of its obligations under its Note Guarantee or this
Indenture, except in accordance with the terms of this Indenture; or

     (9) make any change in the preceding amendment, supplement and waiver provisions.

Section 9.03 Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes will be set forth in an amended
or supplemental indenture that complies with the TIA as then in effect.

Section 9.04 Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a
Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of
the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may

-62-

 

revoke the consent as to its Note if the Trustee receives written notice of revocation
before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Holder; except as
provided in the last paragraph of Section 9.02.

Section 9.05 Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment, supplement or waiver on any
Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee
shall, upon receipt of a Company Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

          Failure to make the appropriate notation or issue a new Note will not affect the validity and
effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

          The Trustee will sign any amended or supplemental indenture authorized pursuant to this
Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. The Issuers may not sign an amended or supplemental indenture until
the Boards of Directors of each of the Issuers approves it. In executing any amended or
supplemental indenture, the Trustee shall receive and (subject to Section 7.01 hereof) will be
fully protected in relying upon, in addition to the documents required by Section 13.05 hereof, an
Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or
supplemental indenture is authorized or permitted by this Indenture. In the case of any amendment
or supplement pursuant to Section 9.01(6) hereof, such Officers’ Certificate shall include a
certification that the conforming change being made to this Indenture reflects the intent of the
Issuers and the Underwriters.

ARTICLE X

AMENDMENT TO ARTICLE XIV OF BASE INDENTURE

          The provisions of Article XIV of the Base Indenture are deleted and replaced in their
entirety, solely as they relate to the Notes, by the provisions of this Article X of this Third
Supplemental Indenture as provided below:

“ARTICLE XIV

NOTE GUARANTEES

Section 14.01 Guarantee.

          (a) Subject to this Article XIV, each of the Guarantors hereby, jointly and severally,
unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and
to the Trustee and its successors and assigns, irrespective of the validity and enforceability of
this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

     (1) the principal of, premium, if any, and interest on, the Notes will be promptly paid
in full when due, whether at stated maturity, by acceleration, redemption or otherwise, and
inter-

-63-

 

est on the overdue principal of and interest on the Notes, if any, if lawful, and all
other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will
be promptly paid in full or performed, all in accordance with the terms hereof and thereof;
and

     (2) in case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated maturity, by
acceleration or otherwise.

          Failing payment when due of any amount so guaranteed or any performance so guaranteed for
whatever reason, the Guarantors will be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of
collection.

          (b) The Guarantors hereby agree that their obligations hereunder are unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with
respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest,
notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged
except by complete performance of the obligations contained in the Notes and this Indenture.

          (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in
relation to either the Issuers or the Guarantors, any amount paid by either to the Trustee or such
Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force
and effect.

          (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation
to the Holders in respect of any obligations guaranteed hereby until payment in full of all
obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on
the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes
of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any
declaration of acceleration of such obligations as provided in Article VI hereof, such obligations
(whether or not due and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Note Guarantee.

Section 14.02 Limitation on Guarantor Liability.

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the
intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any
Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors
hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum
amount that will,

-64-

 

after giving effect to such maximum amount and all other contingent and fixed
liabilities of such Guarantor that are relevant under such laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of
such other Guarantor under this Article XIV, result in the obligations of such Guarantor under
its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 14.03 Execution and Delivery of Note Guarantee.

          To evidence its Note Guarantee set forth in Section 14.01 hereof, each Guarantor hereby agrees
that a notation of such Note Guarantee substantially in the form attached as Exhibit B to the Third
Supplemental Indenture will be endorsed by an Officer of such Guarantor on each Note authenticated
and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor
by one of its Officers.

          Each Guarantor hereby agrees that its Note Guarantee set forth in Section 14.01 hereof will
remain in full force and effect notwithstanding any failure to endorse on each Note a notation of
such Note Guarantee.

          If an Officer whose signature is on this Indenture or on the notation of Note Guarantee no
longer holds that office at the time the Trustee authenticates the Note on which a notation of Note
Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

          The delivery of any Note by the Trustee, after the authentication thereof hereunder, will
constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the
Guarantors.

          In the event that the Issuers or any of Regency Energy Partners’ Restricted Subsidiaries
creates or acquires any Domestic Subsidiary after the date of this Indenture, if required by
Section 4.18 hereof, the Issuers will cause such Domestic Subsidiary to comply with the provisions
of Section 4.18 hereof and this Article XIV, to the extent applicable.

Section 14.04 Guarantors May Consolidate, etc., on Certain Terms.

          Except as otherwise provided in Section 14.05 hereof, no Guarantor may sell or otherwise
dispose of all or substantially all of its properties or assets to, or consolidate with or merge
with or into (whether or not such Guarantor is the surviving Person) another Person, other than
Regency Energy Partners or another Guarantor, unless:

     (1) immediately after giving effect to such transaction, no Default or Event of Default
exists; and

     (2) either:

     (a) subject to Section 14.05 hereof, the Person acquiring the properties or
assets in any such sale or other disposition or the Person formed by or surviving
any such consolidation or merger (other than the Guarantor) unconditionally assumes
all the obligations of that Guarantor under this Indenture and its Note Guarantee on
the terms set forth herein or therein, pursuant to a supplemental indenture
substantially in the form of Exhibit C to the Third Supplemental Indenture; or

-65-

 

     (b) the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of this Indenture, including without
limitation, Section 4.10 hereof.

          In case of any such consolidation, merger, sale or conveyance and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the Trustee, of such
obligations, such successor Person will succeed to and be substituted for the Guarantor with the
same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may
cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the
Notes issuable hereunder which theretofore shall not have been signed by the Issuers and delivered

another Guarantor, such Guarantor will be released and relieved of any obligations under its Note
Guarantee, provided that, if it is also a Domestic Subsidiary, it is no longer an obligor with
respect to any Indebtedness under any Credit Facility; provided, however, that if, at any time
following such release, that Guarantor incurs a Guarantee under a Credit Facility, then such
Guarantor shall be required to provide a Note Guarantee at such time.

Indenture in accordance with Article XI hereof, each Guarantor will be released and relieved of any
obligations under its Note Guarantee.

FORTH IN THE INDENTURE REFERRED TO HEREIN.”

          Capitalized terms used herein have the meanings assigned to them in the Indenture referred to
below unless otherwise indicated.

     (1) Interest. Regency Energy Partners LP, a Delaware limited partnership (“Regency Energy
Partners”), and Regency Energy Finance Corp., a Delaware corporation (“Finance Corp.” and, together
with Regency Energy Partners, the “Issuers”), promise to pay interest on the principal amount of
this Note at 6 1/2% per annum from May 26, 2011 until maturity. The Issuers will pay interest
semi-annually in arrears on January 15 and July 15 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on
the Notes will accrue from the most recent date to which interest has been paid or, if no interest
has been paid, from the date of issuance; provided that if there is no existing Default in the
payment of interest, and if this Note is authenticated between a record date referred to on the
face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be
January 15, 2012. The Issuers will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at the rate then in effect to the extent lawful; they will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest (without regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve
30-day months.

     (2) Method of Payment. The Issuers will pay interest on the Notes (except defaulted interest)
to the Persons who are registered Holders of Notes at the close of business on the January 1 and
July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record
date and on or before such Interest Payment Date, except as provided in Section 2.17 of the
Indenture with respect to defaulted interest. Holders of Definitive Notes must surrender their
Notes to the Paying Agent to collect payments of principal and premium, if any, due at maturity.
The Notes will be payable as to principal, premium, if any, and interest at the office or agency of
the Issuers maintained for such purpose within the continental United States, or, at the option of
the Issuers, payment of interest may be made by check mailed to the Holders at their addresses set
forth in the register of Holders; provided that if a Holder of $5,000,000 or more in principal
amount of Notes has given wire instruction to the Issuers, payment by wire transfer of immediately
available funds will be required with respect to principal of and interest and

A-2

 

premium, if any, on that Holder’s Notes. Such payment will be in such coin or currency of the
United States of America as at the time of payment is legal tender for payment of public and
private debts.

     (3) Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under
the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or
Registrar without notice to any Holder. Regency Energy Partners or any of its Subsidiaries may act
in any such capacity.

     (4) Indenture. The Issuers issued the Notes under an Indenture dated as of October 27, 2010
(the “Base Indenture”) among the Issuers, the guarantors party thereto and the Trustee, as amended
and supplemented by the Third Supplemental Indenture to the Base Indenture, dated as of May 26,
2011 (the “Supplemental Indenture”) among the Issuers, the Guarantors and the Trustee. The Base
Indenture, as amended and supplemented by the Supplemental Indenture, is hereinafter referred to as
the “Indenture.” The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the TIA for a statement of such terms. To the extent any provision
of this Note conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are unsecured obligations of the Issuers.
The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

     (5) Optional Redemption.

     (a) Except as set forth in subparagraphs (b), (c) and (d) of this Paragraph 5, the Issuers
will not have the option to redeem the Notes prior to July 15, 2016. On or after July 15, 2016,
the Issuers may redeem all or a part of the Notes upon not less than 10 nor more than 60 days’
notice, at the redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest on the Notes redeemed to, but excluding, the applicable Redemption
Date, if redeemed during the twelve-month period beginning on July 15 of each year indicated below,
subject to the rights of Holders of Notes on the relevant record date to receive interest on an
Interest Payment Date that is on or prior to the Redemption Date:

	 	 	 	 	 
	Year	 	Percentage	 
	2016
	 	 	103.250	%
	2017
	 	 	102.167	%
	2018
	 	 	101.083	%
	2019 and thereafter
	 	 	100.000	%

     (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior
to July 15, 2014, the Issuers may on any one or more occasions redeem up to 35% of the aggregate
principal amount of Notes (including any Additional Notes) then Outstanding upon not less than 10
nor more than 60 days’ notice, at a redemption price of 106.500% of the principal amount, plus
accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on
the relevant record date to receive interest due on an Interest Payment Date that is on or prior to
the Redemption Date), with the net cash proceeds of one or more Equity Offerings by Regency Energy
Partners; provided that at least 65% of the aggregate principal amount of Notes issued on the date
of the Indenture (excluding Notes held by Regency Energy Partners and its Subsidiaries) remains
Outstanding immediately after the occurrence of such redemption and the redemption occurs within 90
days of the date of the closing of such Equity Offering.

     (c) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior
to July 15, 2016, the Issuers may also redeem all or a part of the Notes, upon not less than 10 nor
more

A-3

 

than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of
Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but
excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to
receive interest due on an Interest Payment Date that is prior to the Redemption Date.

          For purposes of subparagraph (c) of this Paragraph 5, “Applicable Premium” means, with respect
to any Note on any Redemption Date, the greater of (1) 1.0% of the principal amount of the Note or
(2) the excess of: (a) the present value at such Redemption Date of (i) the redemption price of the
Note at July 15, 2016 (such redemption price being set forth in the table appearing in subparagraph
(a)) plus (ii) all required interest payments due on the Note through July 15, 2016 (excluding
accrued but unpaid interest to the Redemption Date), computed using a discount rate equal to the
Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the principal amount of the
Note. In addition, for purposes of subparagraph (c) of this Paragraph 5, “Treasury Rate” means,
with respect to any Redemption Date, the yield to maturity at the time of computation of United
States Treasury securities with a constant maturity (as compiled and published in the most recent
Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two
Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published,
any publicly available source of similar market data)) most nearly equal to the period from the
Redemption Date to July 15, 2016; provided, however, that if such period is not equal to the
constant maturity of a United States Treasury security for which a weekly average yield is given,
Regency Energy Partners shall obtain the Treasury Rate by linear interpolation (calculated to the
nearest one twelfth of a year) from the weekly average yields of United States Treasury securities
for which such yields are given, except that if the period from the Redemption Date to July 15,
2016, is less than one year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year will be used.

     Unless the Issuers default in the payment of the redemption price, interest will cease to
accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date.

     (d) In the event that Holders of not less than 90% of the aggregate principal amount of the
Outstanding Notes accept a Change of Control Offer and Regency Energy Partners purchases all of the
Notes held by such Holders, Regency Energy Partners will have the right, upon not less than 15 nor
more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the
Change of Control Offer, to redeem all of the Notes that remain Outstanding following such purchase
at a redemption price equal to 101% of the aggregate principal amount of Notes redeemed plus
accrued and unpaid interest thereon to, but excluding, the date of redemption, subject to the right
of the Holders of Notes on the relevant record date to receive interest due on an interest payment
date that is prior to the Redemption Date.

     (6) Mandatory Redemption.

          Except as set forth below, the Issuers are not required to make mandatory redemption or
sinking fund payments with respect to the Notes.

     (7) Repurchase at the Option of Holder.

     (a) Upon the occurrence of a Change of Control, Regency Energy Partners will be required to
make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to
$2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase
price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued
and unpaid interest on the Notes repurchased to, but excluding, the date of purchase, subject to
the rights of Holders on the relevant record date to receive interest due on the relevant Interest
Payment Date (the “Change of

A-4

 

Control Payment”). Within 30 days following any Change of Control, Regency Energy Partners
will mail a notice to each Holder setting forth the procedures governing the Change of Control
Offer as required by the Indenture. Payment shall be made no earlier than 20 Business Days and no
later than 60 days from the date such notice is mailed.

     (b) If the Issuers or a Restricted Subsidiary of Regency Energy Partners consummates any Asset
Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $20.0
million, Regency Energy Partners will commence an offer to all Holders of Notes and all holders of
other Indebtedness that is pari passu with the Notes containing provisions similar to those set
forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of
assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum
principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount plus
accrued and unpaid interest to, but excluding, the date of purchase in accordance with the
procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other
pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds,
Regency Energy Partners may use such deficiency for any purpose not otherwise prohibited by the
Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered
into such Asset Sale Offer exceeds the amount of Excess Proceeds, then the Notes and such other
pari passu Indebtedness shall be purchased on a pro rata basis. Holders of Definitive Notes that
are the subject of an offer to purchase will receive an Asset Sale Offer may elect to have such
Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to
the Notes.

     (8) Notice of Redemption. Notice of redemption will be mailed at least 10 days but not more
than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its
registered address, except that redemption notices may be mailed more than 60 days prior to a
Redemption Date if the notice is issued in connection with a defeasance of the Notes or a
satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes
held by a Holder are to be redeemed.

     (9) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes
may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents and the Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers need not exchange or register the transfer of any Note or
portion of a Note selected for redemption, except for the unredeemed portion of any Note being
redeemed in part. Also, the Issuers need not exchange or register the transfer of any Notes for a
period of 15 days before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

     (10) Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for
all purposes.

     (11) Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the
Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at
least a majority in aggregate principal amount of the then Outstanding Notes including Additional
Notes, if any, voting as a single class, and any existing Default or Event of Default or compliance
with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then Outstanding Notes
including Additional Notes, if any, voting as a single class. Without the consent of any Holder of
a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure
any ambiguity, defect or

A-5

 

inconsistency, to provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Issuers’ or a Guarantor’s obligations to Holders of the
Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially
all of the Issuers’ or such Guarantor’s properties and assets, as applicable, to make any change
that would provide any additional rights or benefits to the Holders of Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, to comply with the
requirements of the SEC in order to effect or maintain the qualification of the Indenture under the
TIA, to conform the text of the Indenture or the Note Guarantees to any provision of the
“Description of the Notes” section of the Issuers’ prospectus supplement dated May 26, 2011 to the
base prospectus included in the Issuers’ registration statement on Form S-3 (File No. 333-169901)
relating to the issuance and sale of the Initial Notes, to the extent that such text of the
Indenture or the Notes Guarantees was intended to reflect such provision of the “Description of the
Notes”, to provide for the issuance of Additional Notes in accordance with the limitations set
forth in the Indenture as of the date of the Indenture, to allow any Guarantor to execute a
supplemental indenture and/or a notation of Note Guarantee with respect to the Notes or to reflect
the addition or release of a Note Guarantee in accordance with the Indenture, to secure the Notes
and/or the Note Guarantees, or to provide for the reorganization of Regency Energy Partners as any
other form of entity, in accordance with Section 10.01 of the Indenture.

     (12) Defaults and Remedies. Events of Default include: (i) default for 30 days in the
payment when due of interest on the Notes; (ii) default in the payment when due (at stated
maturity, upon redemption or otherwise) of the principal of, or premium, if any, on the Notes;
(iii) failure by Regency Energy Partners or any Guarantor to timely consummate repurchase offers
under Section 4.10 or 4.15 of the Indenture or to comply with Section 10.01 of the Indenture; (iv)
failure by Regency Energy Partners for 90 days after notice to comply with Section 4.03 of the
Indenture; (v) failure by Regency Energy Partners or any Guarantor for 60 days after written notice
to comply with any of the other agreements in the Indenture; (vi) default under certain other
agreements relating to Indebtedness of Regency Energy Partners or any of its Restricted
Subsidiaries, which default results in the acceleration of such Indebtedness prior to its express
maturity; (vii) certain final judgments for the payment of money that remain undischarged for a
period of 60 days; (viii) certain events of bankruptcy or insolvency with respect to the Issuers or
any of Regency Energy Partners’ Restricted Subsidiaries that is a Significant Subsidiary or any
group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;
and (ix) except as permitted by the Indenture, any Note Guarantee is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect
or any Guarantor or any Person acting on its behalf denies or disaffirms its obligations under such
Guarantor’s Note Guarantee. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all
the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, with respect to Finance
Corp., Regency Energy Partners or any Restricted Subsidiary of Regency Energy Partners that is a
Significant Subsidiary or any group of Restricted Subsidiaries of Regency Energy Partners that,

the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default if it determines that withholding notice is in their
interest, except a Default or Event of Default relating to the payment of principal, interest or
premium, if any. The Holders of a majority in aggregate principal amount of the then Outstanding
Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an
acceleration or waive any existing Default or Event of Default and its consequences under the
Indenture except a continuing Default or Event of Default in the payment of interest or premium, if
any, on, or the principal of, the Notes. The Issuers and the Guarantors are required to deliver to
the Trustee annually a statement regarding compliance with the Indenture, and the

upon the Notes under any Bankruptcy Law, or in case a Custodian shall have been appointed for its
property, or in case of any other similar judicial proceedings relative to any of the Guarantors or
the Issuers or any other obligor upon the Notes, its creditors or its property, the Trustee,
irrespective of whether the principal of the Notes of any series shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand pursuant to the provisions of Section 6.08, shall be entitled and empowered to,
among other things, distribute all amounts received with respect to the claims of the Holders and
of the Trustee on their behalf, and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each such Holder by its acceptance of a Note to make
payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments
directly to such Holders, to pay to the Trustee such amount as shall be sufficient to cover
compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Trustee and owing to it pursuant to Section
7.06 of the Indenture.

[FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

          Supplemental Indenture (this “Supplemental Indenture”), dated as of ___, 20___, among __(the
“Guaranteeing Subsidiary”), Regency Energy Partners LP, a Delaware limited partnership (“Regency
Energy Partners”), Regency Energy Finance Corp. (“Finance Corp.” and, together with Regency Energy
Partners, the “Issuers”), the other Guarantors (as defined in the Indenture referred to herein) and
U.S. Bank National Association, as trustee under the Indenture referred to below (the “Trustee”).

W I T N E S S E T H

          WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an Indenture, dated
as of October 27, 2010, as amended and supplemented by the Third Supplemental Indenture dated as of
May 26, 2011 (as amended and supplemented, the “Indenture”), providing for the issuance of 6 1/2%
Senior Notes due 2021 (the “Notes”);

          WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary
shall execute and deliver to the Trustee a supplemental indenture pursuant to which the
Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the
Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); 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 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 Guarantee. The Guaranteeing Subsidiary hereby agrees 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 XIV thereof.

          3. No Recourse Against Others. No past, present or future director, officer, partner,
member, employee, incorporator, manager or unit holder or other owner of Equity Interest of the
Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Issuers 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. 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.

not affect the construction hereof.

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 Subsidiary
and the Issuers.
