Any such designation by the Board of Directors of a Subsidiary of the Company as an Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the foregoing conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the foregoing 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 shall be deemed to be incurred by a Restricted Subsidiary of the Company as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant). The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if:


(i)	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


(ii)	no Default or Event of Default would be in existence following such designation.

THE NOTES

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may be issued in the form of Definitive Notes or Global Notes, as specified by the Company. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Note will be dated the date of its authentication. The Notes will be in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Notes issued in global form will be substantially in the form of Exhibit A attached hereto (including the Global Note Legend and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each will provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company and the Trustee, by their execution and

delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture will govern and be controlling.

(b) Initial Notes. The Initial Notes will be offered and sold by the Company pursuant to a Purchase Agreement. The Initial Notes will be resold initially only to (i) QIBs in reliance on Rule 144A and (ii) Non-U.S. Persons in reliance on Regulation S. The Initial Notes may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S, subject to the restrictions on transfer set forth herein. Additional Notes offered after the Issue Date may be offered and sold by the Company from time to time in accordance with applicable law. Rule 144A Global Notes will be issued initially in the form of one or more permanent Global Notes in definitive, fully registered form, and Regulation S Global Notes will be issued initially in the form of one or more Global Notes in definitive, fully registered form, in each case without interest coupons and with the Global Note Legend and Private Placement Legend set forth in Exhibit A hereto, which will be deposited on behalf of the purchasers of the Initial Notes represented thereby with the Notes Custodian, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in this Indenture. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee and on the schedules thereto as hereinafter provided.

(c) Book-Entry Provisions. This Section 2.01(c) will apply only to a Global Note deposited with or on behalf of the Depositary.

The Company will execute and the Trustee will, in accordance with this Section 2.01(c), authenticate and deliver initially one or more Global Notes that (a) will be registered in the name of the Depositary for such Global Note or Global Notes or the nominee of such Depositary and (b) will be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the Trustee as custodian for the Depositary.

Participants in the Depositary will have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee will be entitled to treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever. None of the Trustee or any Agent shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Note, for the records of any such Depositary, including records in respect of beneficial ownership interests in respect of any such Global Note, for any transactions between the Depositary and any of its Participants or between or among the Depositary, any such Participant and/or any Holder or owner of a beneficial interest in such Global Note, or for any transfers of beneficial interests in any such Global Note.

Notwithstanding the foregoing, nothing herein will prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a Holder of a beneficial interest in any Global Note.

(d) Certificated Notes. Except as provided in this Section 2.01 or Section 2.03 or Section 2.04, owners of beneficial interests in Global Notes shall not be entitled to receive physical delivery of Definitive Notes.

Section 2.02 Execution and Authentication.

One Officer will sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office or position at the time a Note is authenticated, the Note will nevertheless be valid. The Trustee shall be entitled to rely on such signature as authentic and shall be under no obligation to make any investigation in relation thereto.

A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

Except as otherwise provided herein, the aggregate principal amount of Notes that may be outstanding at any time under this Indenture is not limited in amount. The Trustee will authenticate and deliver: (i) on the Issue Date, an aggregate principal amount of $450.0 million 5.125% Senior Notes Due 2022 and (ii) at any time and from time to time thereafter, Additional Notes for an original issue, in each case in an aggregate principal amount specified in the written order of the Company pursuant to this Section 2.02, together with an Officers’ Certificate and an Opinion of Counsel. Such order shall in each case specify the aggregate principal amount of Notes to be authenticated, the issue price, the issue date and the CUSIP number of such Notes and in the case of any issuance of Additional Notes, shall certify that such issuance is in compliance with Section 2.02, Section 2.14 and Section 4.09 hereof.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. Unless otherwise provided in the appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent for service of notices and demands.

Section 2.03 Registrar and Paying Agent.

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee will act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Note Custodian with respect to the Global Notes. The Company has entered into a letter of representations with DTC in the form provided by DTC and the Trustee and each Agent are hereby authorized to act in accordance with such letter and Applicable Procedures.

Claims against the Company for payment of principal of, premium, if any, or interest on the Notes will become void unless presentment for payment is made (where so required herein) within, in the case of principal, a period of ten years or, in the case of interest or premium, a period of five years, in each case from the applicable original date of payment therefor.

The obligations of the Agents are several and not joint.

Section 2.04 Paying Agent to Hold Money in Trust.

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on the Notes, and will notify the Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee pursuant to this Section 2.04, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and will otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee, at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes, which list may be conclusively relied upon by the Trustee, and the Company will otherwise comply with TIA § 312(a).

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Registrar or a co-registrar with a request:

(x) to register the transfer of such Definitive Notes or

(y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations,

the Registrar or co-registrar will register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Notes surrendered for transfer or exchange:

(i) are duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar or co-registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and

(ii) are being transferred or exchanged pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Definitive Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in substantially the form set forth on the reverse of the Note); or

(B) if such Definitive Notes are being transferred to the Company, a certification to that effect (in substantially the form set forth on the reverse of the Note); or

(C) if such Definitive Notes are being transferred pursuant to an exemption from registration in reliance upon an exemption from the registration requirements of the Securities Act: (1) a certification to that effect (in substantially the form set forth on the reverse of the Note) and (2) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to compliance with the restrictions set forth in the Private Placement Legend set forth in Section 2.06(e)(i) hereof.

(b) Restrictions on Transfer of a Definitive Note for a Beneficial Interest in a Global Note. A Definitive Note may not be exchanged for a beneficial interest in a Rule 144A Global Note or a Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

(i) certification, in the form set forth on the reverse of the Note, that such Definitive Note is being transferred (A) to the Company, (B) to the Registrar for registration in the name of a Holder, without transfer, (C) to a QIB in accordance with Rule 144A, (D) outside the United States in an offshore transaction within the meaning of Regulation S and in compliance with Rule 904 under the Securities Act or (E) pursuant to another available exemption from registration provided by Rule 144 under the Securities Act; and

(ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase,

then the Trustee will cancel such Definitive Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Notes Custodian, the aggregate principal amount of Notes represented by the Global Note to be increased accordingly. If no Global Notes are then outstanding, the Company will issue and the Trustee will authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Note in the appropriate principal amount.

(c) Transfer and Exchange of Global Notes. (i) The transfer and exchange of Global Notes or beneficial interests therein will be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Note will deliver to the Registrar a written order given in accordance with the Depositary’s procedures containing information regarding the Participant account of the Depositary to be credited with a beneficial interest in the Global Note. The Registrar will, in accordance with such instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer by an amount equal to the beneficial interest in the Global Note being transferred. Transfers by an owner of a beneficial interest in the Rule 144A Global Note to a transferee who takes delivery of such interest through the Regulation S Global Note shall be made only upon receipt by the Trustee of a certification in the form provided on the reverse of the Initial Notes from the transferor to the effect that such transfer is being made in accordance with Regulation S or (if available) Rule 144 under the Securities Act.

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Registrar will reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar will reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in Section 2.06(c)(iv) hereof), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(iv) A Global Note deposited with the Depositary or with the Trustee as Notes Custodian for the Depositary pursuant to Section 2.01 will be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.06 hereof and (A) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or if at any time such Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days of such notice, (B) an Event of Default has occurred and

is continuing or (C) the Company, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Notes under this Indenture.

(v) Any Global Note that is transferable to the beneficial owners thereof pursuant to Section 2.06(c)(iv) will be surrendered by the Depositary to the Trustee located at its principal corporate trust office in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee will authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note transferred pursuant to Section 2.06(c)(iv) will be executed, authenticated and delivered only in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any Definitive Note delivered in exchange for an interest in the Transfer Restricted Security will, except as otherwise provided by Section 2.06(e) hereof, bear the restricted securities legend set forth in Exhibit A hereto.

(vi) Subject to the provisions of Section 2.06(c)(v) above, the registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes.

(vii) In the event of the occurrence of any of the events specified in Section 2.06(c)(iv)(A), (B) or (C) above, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Notes in fully registered form without interest coupons.

(viii) Any certificate (i) evidencing a Note that has been transferred to an Affiliate of the Company within one year after the Issue Date, as evidenced by a notation on the assignment form for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Note that has been acquired from an Affiliate (other than by an Affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until one year after the last date on which either the Company or any Affiliate of the Company was an owner of such Note, in each case, be in the form of a permanent Definitive Note and bear the Private Placement Legend subject to the restrictions in Section 2.06(e). The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.03 and this Section 2.06. The Company, at its sole cost and expense, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

(d) [reserved]

(e) Legend.

(i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Note certificate evidencing the Global Notes (and all Notes issued in exchange therefor or in substitution thereof) will bear the Private Placement Legend in substantially the following form:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE OR OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN “OFFSHORE TRANSACTION” PURSUANT TO RULE 903 OR RULE 904 OF REGULATION S, (2) AGREES THAT IT WILL NOT, PRIOR TO THE DATE THAT IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF (OR OF ANY PREDECESSOR OF THIS SECURITY) AND THE LAST DATE ON WHICH SOUTHERN STAR CENTRAL CORP. (THE “ISSUER”) OR ANY AFFILIATE OF THE ISSUER WAS THE OWNER OF THIS SECURITY OR ANY PREDECESSOR OF THIS SECURITY, OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER OR ANY OF ITS SUBSIDIARIES, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED THAT THE ISSUER AND THE TRUSTEE SHALL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (I) PURSUANT TO CLAUSE (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM AND (II) IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATION OF TRANSFER IN THE FORM APPEARING IN THE INDENTURE IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE.

Each Global Note will also bear the Global Note Legend in substantially the following form:

TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(c) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

Each Definitive Note will also bear the following additional legend:

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

(i) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Note) pursuant to Rule 144, the Registrar will permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Note that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Note).

(f) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, redeemed, purchased or canceled, such Global Note will be returned to the Depositary for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, purchased or canceled, the principal amount of Notes represented by such Global Note will be reduced and an adjustment will be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

(g) Obligations with Respect to Transfers and Exchanges of Notes.

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee will authenticate Definitive Notes and Global Notes at the Registrar’s or co‑registrar’s request.

(ii) No service charge will be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 4.13 and 9.05 of this Indenture).

(iii) The Registrar or co‑registrar will not be required to register the transfer of or exchange of (a) any Definitive Note selected for redemption in whole or in part pursuant to Article 3 of this Indenture, except the unredeemed portion of any Definitive Note being redeemed in part, or (b) any Note for a period beginning 15 Business Days before the mailing of a notice of an offer to repurchase or redeem Notes or 15 Business Days before an interest payment date, and ending on such mailing date or interest payment date, as the case may be.

(iv) Prior to the due presentation for registration of transfer of any Note, the Company, the Trustee, the Paying Agent, the Registrar or any co‑registrar may deem and treat the person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co‑registrar will be affected by notice to the contrary.

(v) All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture will evidence the same debt and will be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

(h) No Obligation of the Trustee or Any Agent.

(i) The Trustee and each Agent will have no responsibility or obligation to any beneficial owner of a Global Note, a Participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Participant, with respect to any ownership interest in the Notes or with respect to the delivery to any Participant, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes will be given or made only to or upon the order of the registered Holders (which will be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note will be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee and each Agent may rely and will be fully protected in relying upon information furnished by the Depositary with respect to its Participants and any beneficial owners.

(ii) The Trustee and each Agent will have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon the written order of the Company signed by one Officer of the Company,

will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay all principal, premium, if any, and interest payable on that date with respect to the Notes, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee will authenticate temporary Notes upon a written order of the Company signed by one Officer of the Company. Temporary Notes will be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and that are

reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate Definitive Notes in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes in accordance with its standard procedures (subject to the record retention requirement of the Exchange Act). Certification of all canceled Notes will be delivered to the Company upon written request. The Company may not issue new Notes to replace Notes that it has redeemed, paid or delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date, provided that no such special record date will be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will deliver or cause to be delivered to Holders a notice that states the special record date, the related payment date and the amount of defaulted interest to be paid.

Section 2.13 CUSIP Numbers.

The Company in issuing the Notes may use CUSIP numbers, ISIN numbers (if then generally in use) or other similar numbers, and, if so, the Trustee may use the CUSIP and/or ISIN numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made by the Trustee as to the correctness of such numbers either as printed on the Notes or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Notes, and any such notice will not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers, ISIN numbers or other similar numbers.

Section 2.14 Issuance of Additional Notes.

The Company will be entitled, subject to its compliance with Sections 2.02 and 4.09 hereof, to issue Additional Notes under this Indenture with identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price.

The Initial Notes issued on the Issue Date and any Additional Notes will be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Company will set forth in a resolution of the Board of Directors and an Officers’ Certificate, copies of which will be delivered to the Trustee, the following information:

(i) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(ii) the issue price, the issue date and the CUSIP number of such Additional Notes; and

(iii) such issuance is in compliance with Section 2.02, this Section 2.14 and Section 4.09 of this Indenture.

REDEMPTION AND PREPAYMENT

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it will furnish to the Trustee, at least 45 days before a redemption date (unless a shorter period shall be satisfactory to the Trustee), an Officers’ Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption will occur, that such election has been duly authorized by all requisite corporate action on the part of the Company and complies with this Indenture, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption prices. If the redemption price is not known at the time such notice is to be given, the actual redemption price calculated as described in the terms of the Notes will be set forth in an Officers’ Certificate delivered to the Trustee no later than two Business Days prior to the redemption date.

Section 3.02 Selection of Notes to be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, and the Notes are Global Notes, they will be selected for redemption in accordance with Applicable Procedures. If the Notes are not Global Notes, the Trustee will select Notes for redemption or purchase on a pro rata basis, by lot or by such method as the Trustee in its sole discretion deems fair and appropriate; provided that no Notes of $2,000 or less shall be redeemed in part.

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $2,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $2,000, will be redeemed or purchased. Except as provided in the preceding

sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Company will send or cause to be sent a notice of redemption to each Holder whose Notes are to be redeemed, except that redemption notices may be sent 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 and discharge of this Indenture pursuant to Article 8 or 10 hereof. Notices of redemption may not be conditional. Notes called for redemption become due on the date fixed for redemption.

The notice will identify the Notes to be redeemed (including CUSIP Numbers, if any) and will state:

(i) the redemption date;

(ii) the redemption price plus accrued interest, if any, and, if such redemption is pursuant to Section 3.07(c), the manner of calculation for the Applicable Premium;

(iii) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note (or transferred by book-entry);

(iv) the name and address of the Paying Agent;

(v) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(vi) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(vii) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(viii) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter period shall be satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the form of notice to be given as provided in the preceding paragraph as an exhibit thereto.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is sent 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.

Prior to 11:00 a.m. Eastern Time on the Business Day prior to the redemption date, the Company 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 Company any money deposited with the Trustee or the Paying Agent by the Company 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 Company complies 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 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 will 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 purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest will 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 Company will issue and, upon the Company’s written request, the Trustee will authenticate (or deliver by book entry transaction pursuant to Applicable Procedures) for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

The notice of such redemption shall set forth the manner of calculation for the Applicable Premium. The Company will notify the Trustee of the amount of the Applicable Premium promptly after the calculation thereof (provided that the Trustee will not be responsible for such calculation).

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

The Company 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 Company of its obligation to maintain an office or agency in the continental United States for such purposes. The Company will 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 Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

(ix) Permitted Refinancing Indebtedness, provided that the encumbrances or restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive in any material respect, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined by the Board of Directors of the Company in its good faith judgment;

(x) Liens securing Indebtedness otherwise permitted to be incurred under Section 4.11 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(xi) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business; and

(b) The provisions of Section 4.09(a) shall not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(v) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) hereof or clauses (ii), (iii), (v) or (xiv) of this Section 4.09(b);

(vi) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, that (A) if the Company is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, and (B)(1) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (2) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or a Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi);

(vii) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the normal course of business and not for speculative purposes, designed to protect the Company or such Restricted Subsidiary against fluctuations in interest rates or currency exchange rates with respect to Indebtedness incurred or against fluctuations in the price of commodities used by that entity at the time;

(x) the incurrence by the Company’s Unrestricted Subsidiaries of Non-Recourse Debt;

(xi) Indebtedness incurred in respect of workers’ compensation claims, self-insurance obligations, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business;

(xii) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business;

(xiii) Indebtedness represented by agreements of the Company or a Restricted Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Restricted Subsidiary;

(xiv) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness; and

(xv) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (xv), not to exceed $75.0 million.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) at any time meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xv) of Section 4.09(b) above or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify (and later reclassify at any time) in whole or in part, in its sole discretion, such item of Indebtedness in any manner that complies with this Section 4.09. Indebtedness permitted by this Section 4.09 need not be permitted solely by reference to one clause permitting such Indebtedness but may be permitted (and classified) in part by one such clause and in part by one or more other clauses of this Section 4.09 permitting such Indebtedness.

Section 4.10 Transactions with Affiliates.

(a) The Company 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 (each, an “Affiliate Transaction”), unless:

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

(ii) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.10(a).

(b) The following provisions will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.10(a) hereof:

(i) any employment agreement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with past practices;

(ii) transactions between or among the Company and/or its Restricted Subsidiaries;

(iii) transactions with a Person that is an Affiliate of the Company solely because the Company owns an Equity Interest in, or controls, such Person;

(iv) payment of reasonable directors fees to Persons who are not otherwise Affiliates of the Company;

(vii) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements or stock option or stock ownership plans approved by the Board of Directors;

(viii) loans or advances to employees in the ordinary course of business and consistent with past practices;

(ix) indemnification payments made to officers, directors and employees of the Company or any of its Restricted Subsidiaries pursuant to charter, bylaw, statutory or contractual provisions; and

(x) any agreement in effect as of the Issue Date and described in the Offering Memorandum and any amendment thereto (so long as such amendment is not materially less favorable to the Company or any Restricted Subsidiary).

Section 4.11 Liens.

The Company shall not, and shall 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 or trade payables of the Company upon any of their property or assets, now owned or hereafter acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, unless the Notes are secured on an equal and ratable basis (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes) with the Obligations so secured until such time as such Obligations are no longer secured by a Lien. The Company 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) on the Capital Stock of Southern Star Central Gas Pipeline, Inc.

Section 4.12 Corporate Existence.

Subject to Article 5 hereof, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company will not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.13 Offer to Repurchase upon Change of Control Triggering Event.

(a) Upon the occurrence of a Change of Control Triggering Event, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Company will send a notice to each Holder (with a copy to the Trustee) describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the date specified in such notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”).

Such notice, which will govern the terms of the Change of Control Offer, will state:

(i) that the Change of Control Offer is being made pursuant to this Section 4.13 and that all Notes tendered will be accepted for payment;

(ii) the purchase price and the purchase date;

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

(iv) that, unless the Company 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;

(v) 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” on the reverse of the Notes completed, 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;

(vi) 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

(vii) 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 $1,000 in principal amount or an integral multiple thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.13, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.13 by virtue of such conflict.

(b) On the Change of Control Payment Date, the Company will, to the extent lawful:

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

(ii) deposit with the Paying Agent by 10:00 a.m., Eastern Time, an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and

(iii) 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 thereof being purchased by the Company.

The Paying Agent will promptly pay to each Holder of Notes properly tendered the Change of Control Payment for such Notes, 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, if any; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Prior to complying with any of the provisions of this Section 4.13, but in any event within 90 days following a Change of Control Triggering Event, if the Company is subject to any agreement evidencing Senior Debt (or commitments to extend Senior Debt) that prohibits prepayment of such Senior Debt or repurchase of the Notes pursuant to a Change of Control Offer, the Company will either repay all outstanding Senior Debt (and terminate all commitments to extend such Senior Debt) or obtain the requisite consents, if any, under all agreements governing outstanding Senior Debt or commitments to permit the repurchase of Notes required by this Section 4.13. The Company shall first comply with the covenant set forth in this clause (c) before it shall be required to make a Change of Control Offer or to repurchase Notes pursuant to this Section 4.13. The Company’s failure to comply with this Section 4.13 may (with notice and lapse of time) constitute an Event of Default described in clause (iii) but shall not constitute an Event of Default described in clause (ii) as set forth in Section 6.01.

(d) Notwithstanding anything to the contrary in this Section 4.13, the Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event 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 4.13 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (2) a notice of redemption is outstanding pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement for the Change of Control is in place at the time of the making of the Change of Control Offer.

(e) If Holders of not less than 95% in aggregate principal amount of outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described in this Section 4.13, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described in this Section 4.13, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, thereon, to the date of redemption.

Section 4.14 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default; provided that in no event will any business currently operated by Southern Star Central Gas Pipeline, Inc. be transferred to or held by an Unrestricted Subsidiary. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under clause (xii) of the definition of Permitted Investments, as determined by the Company. That designation will be permitted only if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

Section 4.15 Covenant Termination.

(a) Upon the first date upon which the Notes are rated Baa3 or better by ▇▇▇▇▇’▇ or BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Company as a replacement agency) (the “Investment Grade Rating”) and no Default has occurred and is then continuing under this Indenture (the “Investment Grade Date”), the Company and its Restricted Subsidiaries shall cease to be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.10 and 4.13, which will be deemed to be terminated as of and from such date, provided that the provisions of Sections 4.03, 4.11 and 5.01 will not be so terminated.

(b) The Company will deliver to the Trustee, promptly after the Investment Grade Date, (i) an Officers’ Certificate to the Trustee indicating the occurrence of any Investment Grade Date. The Trustee shall have no obligation to independently determine or verify if such event has occurred or notify the holders of the occurrence of any Investment Grade Date, or any date the Notes may no longer have an investment grade rating, or such rating is suspended or withdrawn. The Trustee may provide a copy of such Officers’ Certificate to any holder of Notes upon request.

(ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes and this Indenture pursuant to a supplemental indenture reasonably satisfactory to the Trustee; and

ARTICLE 6.

(iii) the Company or any of its Restricted Subsidiaries fails to comply with any of the provisions of Section 4.13 or 5.01 hereof;

(iv) the Company or any of its Restricted Subsidiaries fails to comply with any of the provisions of Section 4.07 or 4.09 hereof for 30 days after notice of such failure to the Company from the Trustee or Holders of at least 25% in principal amount of the Notes to the Company and the Trustee;

(vii) a default occurs under any mortgage, other indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default:

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

(B) results in the acceleration of such Indebtedness prior to its Stated 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 $50.0 million or more;

(viii) the Company or any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law:

(A) commences a voluntary case,

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

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

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

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

(C) orders the liquidation of the Company or any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary;

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

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (viii) or (ix) of Section 6.01 hereof, 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 principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

However, a Default under clause (iv), (v) or (vi) of Section 6.01 hereof will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Notes notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice.

In the case of an Event of Default specified in clause (vii) of Section 6.01 hereof, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded with respect to the Notes, automatically and without any action by the Trustee or the Holders, if within 60 days after such Event of Default first arose the Company delivers an Officers’ Certificate to the Trustee stating that (1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (2) the holders of the Indebtedness have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (3) the default that is the basis for such Event of Default has been cured; provided, however, that in no event shall an acceleration of the principal amount of such series of Notes as described in this Section 6.02 be annulled, waived or rescinded upon the happening of any such events.

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 of, 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 will 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 and its consequences hereunder, except a continuing Default in the payment of the principal of, or interest or premium, if any, 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 then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration, if the rescission would not conflict with any judgment and decree and if all existing Events of Default have been cured or waived and all amounts owing to Trustee have been paid. Upon any such waiver, such Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured for every purpose of this Indenture; but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in 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 or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) or that may involve the Trustee in personal liability. The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 6.06 Limitation on Suits.

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

(a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default;

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

(c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the 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 of, 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, will not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

ARTICLE 8.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, will execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section 8.04, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due;

(ii) the Company’s obligations with respect to such Notes under Sections 2.06, 2.07, 2.10 and 4.02 hereof;

(iii) the rights, powers, trusts, duties and immunities of the Trustee under this Indenture and the Company’s obligations in connection therewith and

(iv) this Section 8.02.

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, shall be released from its obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.14 and Article 5 hereof with respect to the outstanding Notes on and after the date the conditions set forth below 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). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company 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 will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(iii) through 6.01(ix) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

(i) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants delivered to the Trustee, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

(ii) in the case of an election under Section 8.02 hereof, the Company will deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable U.S. federal income tax law; in either case to the effect that, and based thereon such Opinion of Counsel will 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 U.S. 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;

(iii) in the case of an election under Section 8.03 hereof, the Company will 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 U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. 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;

(iv) no Default has occurred and is continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91^st day after the day of deposit;

(v) 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 the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

(vi) the Company will deliver to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

(viii) the Company will deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to Legal Defeasance or Covenant Defeasance have been complied with.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(i) 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 8.06 Repayment to Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, 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 will be paid to the Company on its written request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company 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 Company.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 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 Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company 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.

Upon (x) the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture and (y) receipt by the Trustee of the documents described in Section 7.02 (b) hereof, the Trustee will join with the Company 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 Company and the Trustee may amend or supplement this Indenture (including, without limitation, Section 4.13 hereof) or the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default (other than a Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

Upon (x) the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, (y) the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid and (z) receipt by the Trustee of the documents described in Section 7.02(b) hereof, the Trustee will join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture 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.

The Company may, but will not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders of Notes on such record date, or their duly designated proxies, and only such Persons, will be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided, that unless such consent will have become effective by virtue of the requisite percentage having been obtained prior to the date which is 180 days after such record date; any such consent previously given will automatically and without further action by any Holder be canceled and of no further effect.

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

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company 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. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority

in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes.

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

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

(ii) reduce the principal of or change the fixed maturity of any Note or reduce the premium payable upon the redemption of any Note on any date, except as provided above with respect to Section 4.13 hereof, provided that any amendment to the minimum notice requirement may be made with the consent of the holders of a majority in aggregate principal amount of the Notes then outstanding;

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

(iv) waive a Default in the payment of principal of, or interest or premium, if any, 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);

(v) make any Note payable in currency other than that stated in the Notes;

(vi) 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;

(vii) waive a redemption payment with respect to any Note (other than a payment required by Section 4.13 hereof);

(viii) make any change in the ranking or priority of any Note that would adversely affect the Holder of a Note; or

(ix) make any change in Section 6.04 or 6.07 hereof or in the foregoing provisions of this paragraph.

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

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 Company in exchange for all Notes may issue and the Trustee will 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 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive, and (subject to Section 7.01 hereof) will be fully protected in relying upon, 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, and is the legal, valid and binding of the Company in accordance with its terms, subject to customary exceptions.

ARTICLE 10.

SATISFACTION AND DISCHARGE

Section 10.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued thereunder, when:


(i)	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 been deposited in trust and thereafter repaid to the Company, 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 sending of a notice of redemption or otherwise and the Company has irrevocably deposited or caused to be deposited with the Trustee as 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 of principal, premium, if any, and accrued interest to the date of maturity or redemption;


(ii)	no Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;


(iii)	the Company has paid or caused to be paid all sums payable by the Company under this Indenture; and


(iv)	the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be.

In addition, the Company 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 has been deposited with the Trustee pursuant to Section 10.01(i)(B) hereof, the provisions of Section 10.02 and Section 8.06 will survive. In addition, nothing in this Section 10.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 10.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 10.01 will 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 the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and 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 10.01 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 Company’s obligations under this Indenture and the Notes will be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company will 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 11.

Attention: Corporate Trust Administration (Fax: (▇▇▇) ▇▇▇-▇▇▇▇)

The Company or the Trustee, by notice to the others, may designate additional or different addresses for subsequent notices or communications.

All notices and communications (other than those sent to Holders) will be deemed to have been duly given, at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt acknowledged, if telecopied; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

Any notice or communication to a Holder will be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar. Any notice or communication will also be so mailed to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to mail a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders. Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any Note provides for notice of any event (including any notice of redemption or repurchase) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing instructions from the Depositary or its designee, including by electronic mail in accordance with Applicable Procedures.

If a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

If the Company mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Section 11.03 Communications By Holders of Notes with Other Holders of Notes.

Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Company, the Trustee, the Registrar and anyone else will have the protection of TIA § 312(c).

Section 11.04 Certificate and Opinion as to Conditions Precedent.

Upon any request or application by the Company to the Trustee to take any action under this Indenture, the Company will furnish to the Trustee:

(a) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which will include the statements set forth in Section 11.05 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if

any, provided for in this Indenture relating to the proposed action have been satisfied; and

(b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which will include the statements set forth in Section 11.05 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants, if any, have been satisfied.

Section 11.05 Statements Required in Certificate or Opinion.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to Section 4.04 or TIA § 314(a)(4)) will comply with the provisions of TIA § 314(e) and will include:

(a) a statement that the Person making such certificate or opinion has read such covenant or condition;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(c) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been satisfied; and

(d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied.

Section 11.06 Rules by Trustee and Agents.

The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

Section 11.07 No Personal Liability of Directors, Officers, Employees and Stockholders.

No director, officer, employee, incorporator or stockholder of the Company will have any liability for any obligations of the Company under the Notes or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of 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 U.S. federal securities laws and it is the view of the Commission that such a waiver is against public policy.

Section 11.08 Governing Law; Jury Trial Waiver.

THIS INDENTURE AND THE NOTES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. THE PARTIES HERETO AND THE HOLDERS HEREBY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS INDENTURE, THE NOTES, OR ANY TRANSACTION CONTEMPLATED THEREBY, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. THE COMPANY AND THE TRUSTEE REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS INDENTURE MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

Section 11.09 No Adverse Interpretation of Other Agreements.

This Indenture may not be used to interpret any other indenture, loan or debt agreement of the Company or its Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

Section 11.10 Successors.

All agreements of the Company in this Indenture and the Notes will bind its successors. All agreements of the Trustee in this Indenture will bind its successors.

Section 11.11 Severability.

In case any provision in this Indenture or in the Notes will be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby.

Section 11.12 Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy will be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

Section 11.13 Table of Contents, Headings, etc.

The table of contents, cross-reference table and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and will in no way modify or restrict any of the terms or provisions hereof.

Section 11.14 U.S.A. Patriot Act.

The Company acknowledges that in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. PATRIOT Act.

[FORM OF REVERSE SIDE OF NOTE]

5.125% Senior Notes due 2022

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

1. INTEREST. Southern Star Central Corp., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 5.125% per annum from June 16, 2014 until maturity. The Company will pay interest semi-annually 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”), with the same force and effect as if made on the date for such payment. 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 and including the date of original 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 will accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date will be January 15, 2015. The Company 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 a rate that is 1% per annum in excess of the rate then in effect; it 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 Company 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 or July 1 next (whether or not a Business Day) 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 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose within The City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their respective addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, and interest and premium, if any, on all Global Notes and all other Notes the Holders of which have provided wire transfer instructions to the Company or the Paying Agent if such Holders are registered Holders of at least $250,000 in principal amount of the 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, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

4. INDENTURE. The Company issued the Notes under an Indenture dated as of June 16, 2014 (“Indenture”) between the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the

A-5

Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act 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 will govern and be controlling.

5. OPTIONAL REDEMPTION.

(a) On and after July 15, 2017, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on July 15 of the years indicated below:



Year	Percentage
2017	103.844	%
2018	102.563	%
2019	101.281	%
2020 and thereafter	100.000	%

(b) Notwithstanding the foregoing, at any time prior to July 15, 2017, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture at a redemption price of 105.125% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the redemption date, with the net cash proceeds of one or more Equity Offerings by the Company; provided that at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of each such redemption (excluding Notes held by the Company and its Subsidiaries); and provided, further, that any such redemption occurs within 180 days of the date of the closing of such Equity Offering.

(c) In addition, at any time and from time to time prior to July 15, 2017, the Company may redeem all or a portion of the Notes at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium plus accrued and unpaid interest, if any, thereon, to the redemption date. The Company will notify the Trustee of the amount of the Applicable Premium promptly after the calculation thereof (provided that the Trustee will not be responsible for such calculation).

6. MANDATORY REDEMPTION.

The Company is not required to make mandatory redemption payments with respect to the Notes.

7. REPURCHASE AT OPTION OF HOLDER.

If there is a Change of Control Triggering Event, the Company will be required to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase price equal to 101% of aggregate principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the

A-6

Company will send a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required by the Indenture and described in such notice.

8. NOTICE OF REDEMPTION. Notice of redemption will be sent at least 30 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 sent 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 and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $2,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on Notes or portions thereof called for redemption.

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 Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company 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, it 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 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, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation or sale of all or substantially all of the Company’s assets, 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 under the Indenture of any such Holder or to provide for the issuance of Additional Notes in accordance with the provisions set forth in the Indenture or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

12. DEFAULTS AND REMEDIES. An “Event of Default” occurs if: (i) the Company defaults in the payment when due of interest on the Notes and such default continues for a period of 30 days; (ii) the Company defaults in the payment when due of the principal of, or premium, if any, on the Notes; (iii) the Company or any of its Restricted Subsidiaries fails to comply with

A-7

any of the provisions contained in Sections 4.13 or 5.01 of the Indenture; (iv) the Company or any of its Restricted Subsidiaries fails to comply with any of the provisions contained in Sections 4.07 or 4.09 of the Indenture for 30 days after notice of such failure to the Company from the Trustee or Holders of at least 25% in principal amount of the Notes to the Company and the Trustee; (v) the Company fails to comply with any of the provisions contained in Section 4.03 of the Indenture for 90 days after notice of such failure to the Company from the Trustee or Holders of at least 25% in principal amount of the Notes to the Company and the Trustee; (vi) the Company or any of its Restricted Subsidiaries fails to comply with or perform any other agreement in the Indenture or the Notes for 60 days after notice of such failure to the Company from the Trustee or Holders of at least 25% in principal amount of the Notes to the Company and the Trustee; (vii) a default occurs under any mortgage, other indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the date of the Indenture, which default is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”) or results in the acceleration of such Indebtedness prior to its Stated 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 $50.0 million or more; and (viii) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary.

If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all outstanding 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 the Company or any Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in 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 with respect to a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on the Notes.

In the case of an Event of Default specified in clause (vii) of Section 6.01 of the Indenture, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded with respect to the Notes, automatically and without any action by the Trustee or the Holders, if within 60 days after such Event of Default first arose the Company delivers an Officers’ Certificate to the Trustee stating that (1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (2) the holders of the Indebtedness have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (3) the default that is the basis for such Event of Default has been cured; provided, however, that in no event shall an acceleration of

A-8

the principal amount of such series of Notes as described in this paragraph 12 be annulled, waived or rescinded upon the happening of any such events.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may, on behalf of the Holders of all of the Notes, 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 principal of, or interest or premium, if any, 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 then outstanding Notes may rescind an acceleration and its consequences, including any payment default that resulted from such acceleration, if the rescission would not conflict with any judgment or decree or if all existing Events of Default have been cured or waived. Upon any such waiver, such Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured for every purpose of the Indenture; but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

14. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company will have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Noted by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the 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 Commission that such a waiver is against public policy.

15. AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

16. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (tenants in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (custodian), and U/G/M/A (Uniform Gifts to Minors Act).

17. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

18. GOVERNING LAW. This Note will be governed by, and construed in accordance with, the laws of the State of New York. The Company, the Trustee and each Holder irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the Indenture, the Notes or any transaction contemplated thereby.
