For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (as determined in accordance with GAAP) that have been made by the Company or any Restricted Subsidiary during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (and the change in any associated fixed charges and the change in EBITDA resulting therefrom) had occurred on the first day of the reference period.

For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate.

“Fixed Charges” means, with respect to any Person for any period, the sum of

Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date. Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company or any Subsidiary Guarantor in reliance thereon, whether or not notation of such action is made upon such Note.

Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part.

(2) the Company or any Subsidiary Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or delivered in writing and mailed, first-class postage prepaid, or delivered by recognized overnight courier, to the Company or such Subsidiary Guarantor addressed to it at SemGroup Corporation, Two Warren Place, 6120 S. Yale Avenue, Suite 700, Tulsa, Oklahoma 74136-4216; Attn: General Counsel and Secretary, with a copy to Gibson, Dunn & Crutcher LLP, 200 Park Avenue, New York, New York 10166. Attention: Darius Mehraban (Facsimile: 212.351.5270).

instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee acts upon such instructions as required or permitted by this Indenture, then 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 instructions conflict or are inconsistent with a subsequent written instruction.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Notices given by publication shall be deemed given on the first date on which publication is made and notices given by first class mail, postage prepaid, shall be deemed given five calendar days after mailing. Notices given electronically will be deemed given when sent.

In case by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

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

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

The Article and Section headings herein, the Table of Contents and the reconciliation and tie between the TIA and this Indenture are for convenience of reference only, are not intended to be considered a part hereof and shall in no way affect the construction of, or modify or restrict, any of the terms or provisions hereof.

Each Holder by accepting a Note and the related Subsidiary Guarantee waives and releases all such liability to the extent permitted by applicable law. The waiver and release are part of the consideration for issuance of the Notes and the Subsidiary Guarantees.

SECTION 115. Trust Indenture Act Controls. Upon qualification of this Indenture under the TIA, if any provision of this Indenture limits, qualifies or conflicts with another provision which is required to be included in this Indenture by the TIA, the provision required by the TIA shall control.

At any time and from time to time after the Issue Date, the Company may deliver Additional Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Additional Notes, directing the Trustee to authenticate the Additional Notes and certifying that the issuance of such Additional Notes is in compliance with Article Ten hereof and that all other conditions precedent to the issuance of Notes contained herein have been fully complied with, and the Trustee in accordance with such Company Order shall authenticate and deliver such Additional Notes.

Upon receipt of a Company Order, the Trustee shall authenticate for original issue Exchange Notes in an aggregate principal amount not to exceed $300,000,000; provided that such Exchange Notes shall be issuable only upon the valid surrender for cancellation of Initial Notes and any Additional Notes of a like aggregate principal amount in accordance with an Exchange Offer pursuant to the Registration Rights Agreement and a Company Order for the authentication and delivery of such Exchange Notes and certifying that all conditions precedent to the issuance of such Exchange Notes are complied with. In each case, the Trustee shall receive a Company Order, an Officer’s Certificate and an Opinion of Counsel of the Company that it may reasonably require in connection with such authentication of Notes. Such Company Order shall specify the amount of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for in the applicable exhibit to the Appendix, duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon the applicable Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

In case the Company or any Subsidiary Guarantor, pursuant to Article Eight of this Indenture, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Company or such Subsidiary Guarantor shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed a supplemental indenture hereto with the Trustee pursuant to Article Eight of this Indenture, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Request of the successor Person, shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered in such new name.

SECTION 301. Title and Terms. The aggregate principal amount of Notes which may be authenticated and issued under this Indenture is not limited; provided, however, that any Additional Notes issued under this Indenture rank pari passu with the Initial Notes, are issued in accordance with Sections 202 and 1011 hereof, form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise as the Initial Notes. Any Additional Notes shall be issued pursuant to a supplemental indenture to this Indenture.

The Notes shall be known and designated as the “7.50% Senior Notes Due 2021” of the Company. The stated maturity of the Notes shall be June 15, 2021 (the “Stated Maturity”), and the Notes shall bear interest at the rate provided in the Notes from June 14, 2013, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal thereof is paid or duly provided for and to the Person in whose name the Note (or any Predecessor Note) is registered at the close of business on the June 1 and December 1 immediately preceding such Interest Payment Date (each, a “Regular Record Date”).

The principal of (and premium, if any), interest and Additional Interest, if any, on the Notes shall be payable at the office or agency of the Company maintained for such purpose or, at the option of the Company, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the Note Register; provided that all payments of principal, premium, if any, and interest and Additional Interest, if any, with respect to Notes represented by one or more permanent global Notes registered in the name of or held by the Depository or its nominee shall be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof.

Holders shall have the right to require the Company to purchase their Notes, in whole or in part, in the event of a Change of Control pursuant to Section 1017. The Notes shall be subject to repurchase pursuant to an offer to purchase as provided in Section 1018.

The Notes shall be redeemable as provided in Article Eleven of this Indenture and Paragraph 5 of the Notes.

The due and punctual payment of principal of, premium, if any, and interest on the Notes payable by the Company is irrevocably unconditionally guaranteed, to the extent set forth herein, by each of the Subsidiary Guarantors.

SECTION 302. Denominations. The Notes shall be issuable only in registered form without coupons and only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

SECTION 303. Temporary Notes. Pending the preparation of definitive Notes, the Company may execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes.

If temporary Notes are issued, the Company shall cause definitive Notes to be prepared without unreasonable delay. Subject to the provisions set forth in the Rule 144A/Regulation S Appendix, after the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes.

SECTION 304. Note Registrar; Paying Agent; Registration of Transfer and Exchange . The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as note registrar (the “Note Registrar”) for the purpose of registering Notes and transfers of Notes as herein provided. The Trustee is hereby initially appointed to act as the Paying Agent and to act as Custodian with respect to the Global Notes.

Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 1002, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount.

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive; provided that no exchange of Notes for Exchange Notes shall occur until an Exchange Offer Registration Statement shall have been declared effective by the SEC, the Trustee shall have received an Officer’s Certificate confirming that the Exchange Offer Registration Statement has been declared effective by the SEC and the Initial Notes to be exchanged for the Exchange Notes shall be cancelled by the Trustee.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Note Registrar) be duly endorsed, or be accompanied by written instruments of transfer, in form satisfactory to the Company and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Company may require payment of a sum sufficient to cover any taxes, fees or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 202, 303, 906, 1017, 1018 or 1108 not involving any transfer.

SECTION 305. Mutilated, Destroyed, Lost and Stolen Notes. If (1) any mutilated Note is surrendered to the Trustee, or (2) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such security or indemnity 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, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a Protected Purchaser (as defined in Section 8-303 of the Uniform Commercial Code) (a “Protected Purchaser”), the Company shall execute and upon Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in replacing a Note.

Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company and each Subsidiary Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

(a) Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 1002; provided that, subject to Section 301 hereof, each installment of interest may at the Company’s option be paid by (1) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 307, to the address of such Person as it appears in the Note Register or (2) transfer to an account located in the United States maintained by the payee.

(b) Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company at its election, in each case as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall 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, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such Special Record Date, and in the name and at the expense of the Company, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided for in Section 107, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

(c) Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 307. Persons Deemed Owners. Prior to the due presentment of a Note for registration of transfer, the Company, any Subsidiary Guarantor, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 304 and 306) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 308. Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold, and all Notes so delivered shall be promptly cancelled by the Trustee. If the Company shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures (subject to the record retention requirements of the Exchange Act). Certification of the cancellation of all cancelled Notes shall be delivered to the Company by the Trustee upon written request of the Company.

SECTION 309. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 310. Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Note Registrar or a co-registrar with a request to register a transfer, the Note Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Notes are presented to the Note Registrar or a co-registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Note Registrar shall make the exchange as requested if the same requirements are met.

SECTION 311. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case, if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such “CUSIP” numbers, ISINs and “Common Code” numbers in addition to serial numbers in notices of redemption, repurchase or other notices to Holders as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such “CUSIP” numbers, ISINs and “Common Code” numbers either as printed on the Notes or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers, ISINs and “Common Code” numbers applicable to the Notes.

SECTION 312. Issuance of Additional Notes. The Company may, subject to Section 1011 of this Indenture, issue additional Notes having identical terms and conditions to the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price (the “Additional Notes”). The Initial Notes issued on the Issue Date and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture; provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, they will be issued with a different CUSIP. Exchange Notes issued in exchange for Initial Notes issued on the Issue Date and Exchange Notes issued for any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture; provided that if the Exchange Notes are not fungible with the Initial Notes and/or Additional Notes, as applicable, for U.S. federal income tax purposes, they will be issued with a different CUSIP.

SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request and at the Company’s expense cease to be of further effect as to all Notes issued hereunder (except as set forth in the last paragraph of this Section and as to surviving rights of registration of transfer or exchange of Notes expressly provided for herein or pursuant hereto) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when:

(A) all such Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 305 and (ii) Notes for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

(i) have become due and payable by reason of the making of a notice of redemption pursuant to Section 1105 or otherwise, or

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company or any Subsidiary Guarantor, in the case of (i), (ii) or (iii) of this clause (B), has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as shall be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption, as the case may be;

(2) in respect of clause (1)(B) above, no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar deposit relating to other Indebtedness and, in each case, and the granting of Liens in connection therewith) with respect to this Indenture or the Notes issued hereunder shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit shall not result in a breach or violation of, or constitute a default under, the Senior Credit Facility or any other material agreement or instrument (other than this Indenture) to which the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar deposit relating to other Indebtedness and, in each case, and the granting of Liens in connection therewith);

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

(4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Notes at Maturity or the Redemption Date, as the case may be; and

(5) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the satisfaction and discharge of this Indenture have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money or Government Securities shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive such satisfaction and discharge. In addition, nothing in this Section 401 shall be deemed to discharge the obligations of the Company to the Trustee under Section 607 and the obligations of the Company to any Authenticating Agent under Section 612 that, by their terms, survive the satisfaction and discharge of this Indenture.

SECTION 402. Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money or Government Securities deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money or Government Securities has been deposited with the Trustee, but such money or Government Securities 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 401 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 and any Subsidiary Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 401; 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 shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

SECTION 501. Events of Default. “Event of Default,” wherever used herein, means any one of the following events:

(1) default in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the Notes issued under this Indenture;

(2) default for 30 days or more in the payment when due of interest on or with respect to the Notes issued under this Indenture;

(4) failure by the Company or any Subsidiary Guarantor for 60 days after receipt of written notice given by the Trustee or the Holders of at least 25% in principal amount of the then Outstanding Notes issued under this Indenture voting as a single class to comply with any of the other agreements contained in this Indenture or the Notes;

(5) failure by the Company or any Subsidiary Guarantor to make a Change of Control Offer or an Asset Sale Offer within the time periods set forth in Section 1017 or 1018, or to consummate a purchase of Notes when required pursuant to Section 1017 or 1018 or to comply with the provisions of Article Eight;

(6) default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company or any Restricted Subsidiary or the payment of which is guaranteed by the Company or any Restricted Subsidiary, other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created after the issuance of the Notes, if both

(i) results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or

(ii) relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its Stated Maturity and

(B) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $40.0 million or more at any one time outstanding;

(7) failure by the Company or any Restricted Subsidiary that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $40.0 million, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed;

(8) any of the following events with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary:

(A) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law;

and, solely with respect to clause (B), the order or decree remains unstayed and in effect for 60 consecutive days; provided, that for the purposes of this clause (8), a Significant Subsidiary shall include any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary; or

(9) the Subsidiary Guarantee of any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) shall for any reason cease to be in full force and effect or be declared null and void or any responsible officer of any Subsidiary Guarantor that is a Significant Subsidiary (or the responsible officers of any group of Subsidiaries that together would constitute a Significant Subsidiary), as the case may be, denies that it has any further liability under its Subsidiary Guarantee or gives notice to such effect, other than by reason of the termination of this Indenture or the release of any such Subsidiary Guarantee in accordance with this Indenture.

(a) If any Event of Default (other than an Event of Default specified in Section 501(8)) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes issued under this Indenture may declare the principal, premium, if any, interest and any other monetary Obligations on all the Outstanding Notes issued under this Indenture to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by the Holders).

(b) Upon the effectiveness of such declaration, such principal of and premium, if any, and interest on the Notes shall be due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in Section 501(8) occurs and is continuing with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Restricted Subsidiary), then the principal amount of all Outstanding Notes shall ipso facto become and be immediately due and payable without any notice, declaration or other act on the part of the Trustee or any Holder.

(c) At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(2) Events of Default, other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(d) Notwithstanding the preceding paragraph, in the event of any Event of Default specified in Section 501(6) above, such Event of Default and all consequences thereof (excluding any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose,

(1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged, or

(2) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default, or

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. If an Event of Default specified in Section 501(1) or (2) occurs and is continuing, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums due hereunder pursuant to this Article 5 and unpaid, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor including any Subsidiary Guarantor, upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(2) to collect, receive and distribute any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505. Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

SECTION 506. Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

THIRD: The balance, if any, to the Company or as a court of competent jurisdiction may direct in writing; provided that all sums due and owing to the Holders and the Trustee have been paid in full as required by this Indenture.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 506.

SECTION 507. Limitation on Suits. Subject to Section 508, no Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2) Holders of at least 25% in principal amount of the Outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee reasonable security or indemnity reasonably satisfactory to it against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

(5) Holders of a majority in principal amount of the Outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period,

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or the Subsidiary Guarantees to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture or the Subsidiary Guarantees, except in the manner herein provided and for the equal and ratable benefit of all the Holders (it being further understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Eleven) and in such Note of the principal of (and premium, if any) and (subject to Section 306) interest on such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment on or after such respective dates, and such rights shall not be impaired without the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture or the Subsidiary Guarantees and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, any Subsidiary Guarantor, any other obligor of the Notes, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 305, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. Control by Holders. The Holders of not less than a majority in principal amount of the Outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided that:

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) subject to Section 315 of the Trust Indenture Act, the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders not consenting.

SECTION 513. Waiver of Default. Subject to Sections 508 and 902, the Holders of not less than a majority in principal amount of the Outstanding Notes may on behalf of the Holders of all such Notes, rescind an acceleration, waive any Default of Event of Default hereunder and its consequences, except a continuing Default or Event of Default (1) in respect of the payment of interest on, premium, if any, or the principal of any such Note held by a non-consenting Holder, or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 514. Waiver of Stay or Extension Laws. Each of the Company, the Subsidiary Guarantors and any other obligor on the Notes covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force that would prohibit or forgive the Company or a Subsidiary Guarantor from paying any portion of the principal of, and premium, if any, and interest on the Notes.

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith or willful misconduct on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions specifically required by any provision hereof to be provided to it, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but not to verify the contents thereof.

(b) If an Event of Default has occurred and is continuing of which a Responsible Officer of the Trustee has actual knowledge or of which written notice of such Event of Default shall have been given to the Trustee by the Company, any other obligor of the Notes or by any Holder, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that

(1) this paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in aggregate principal amount of the Outstanding Notes relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

SECTION 602. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall transmit, in the manner and to the extent provided in TIA Section 313(c), notice of such Default or Event of Default within 90 days after it occurs unless such Default or Event of Default shall have been cured or waived. Except in the case of a Default or Event of Default in the payment of the principal of (or premium, if any, on) or interest on any Note, the Trustee shall be protected in withholding such notice if it determines that the withholding of such notice is in the interest of the Holders. In addition, the Trustee shall have no obligation to accelerate the Notes if in the judgment of the Trustee acceleration is not in the interest of the Holders of such Notes.

SECTION 603. Certain Rights of Trustee. Subject to the provisions of TIA Sections 315(a) through 315(d):

(1) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document (whether in original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper party or parties;

(2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of Directors of the Company may be sufficiently evidenced by a Board Resolution of the applicable Board of Directors;

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s Certificate and/or an Opinion of Counsel;

(4) the Trustee may consult with counsel of its own selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the advice or opinion of such counsel;

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses, losses and liabilities which might be incurred by it in compliance with such request or direction;

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation;

(7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(8) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence;

(9) the rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and

(10) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

SECTION 604. Trustee Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except for the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Company are true and accurate, subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Company of Notes or the proceeds thereof.

SECTION 605. May Hold Notes. The Trustee, any Paying Agent, any Note Registrar or any other agent of the Company or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not the Trustee, Paying Agent, Note Registrar or such other agent; provided, however, that, if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

SECTION 606. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

(1) The Company agrees to pay to the Trustee from time to time such compensation as shall be agreed in writing between the Company and the Trustee for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) The Company agrees to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall be determined to have been caused by its own negligence or willful misconduct; and

(3) The Company and the Subsidiary Guarantors, jointly and severally, agree to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any and all loss, liability, claim, damage or expense, including taxes (other than the taxes based on the income of the Trustee), incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this Indenture, the Notes and the trust created hereby (including the costs and expenses of defending itself against any claim regardless of whether the claim is asserted by the Company, a Subsidiary Guarantor, a Holder or any other Person) or arising out of or in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Subsidiary Guarantors of their obligations hereunder. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

The obligations of the Company under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder. As security for the performance of such obligations of the Company, the Trustee shall have a lien prior to the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any) or interest on particular Notes.

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(8), the expenses (including the reasonable charges and expenses of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy Law.

The provisions of and obligations of the Company under this Section shall survive the satisfaction, discharge and termination of this Indenture and resignation or removal of the Trustee.

SECTION 608. Corporate Trustee Required; Eligibility. There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of Federal, State, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 610.

(b) The Trustee may resign at any time by giving written notice thereof to the Company at least 30 days prior to the effective date of such resignation. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument executed by authority of the Board of Directors of the Company, a copy of which shall be delivered to the resigning Trustee and a copy to the successor Trustee. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, or the Company or the Holders of at least 10% in aggregate principal amount of Outstanding Notes may petition, any court of competent jurisdiction for the appointment of a successor Trustee.

(c) The Trustee may be removed at any time by Act of the Holders of not less than a majority in principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, or the Company or the Holders of at least 10% in aggregate principal amount of Outstanding Notes may petition, any court of competent jurisdiction for the appointment of a successor Trustee.

(d) The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 608 hereof, (2) the Trustee is adjudged to a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law, (3) a custodian or public officer takes charge of the Trustee or its property, or (4) the Trustee becomes incapable of acting.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution of the Board of Directors of the Company, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to the Holders in the manner provided for in Section 107. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

(a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

(b) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 611. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder without any further act; provided that such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 612. Appointment of Authenticating Agent. At any time when any of the Notes remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to the Notes which shall be authorized to act on behalf of the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment to all Holders of Notes with respect to which such Authenticating Agent shall serve, in the manner provided for in Section 107. Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent; provided that such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give written notice of such appointment to all Holders of Notes, in the manner provided for in Section 107. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time such compensation for its services under this Section as shall be agreed in writing between the Company and such Authenticating Agent.

If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Notes designated therein referred to in the within-mentioned Indenture.

SECTION 701. Holder Lists. The Trustee shall 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 shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Note Registrar, the Company shall furnish to the Trustee at least two Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing within 30 days after receipt by the Company of any such request, 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 and the Company shall otherwise comply with Trust Indenture Act Section 312(a).

SECTION 702. Disclosure of Names and Addresses of Holders. Every Holder, by receiving and holding Notes, agrees with the Company and the Trustee that none of the Company or the Trustee or any agent of either of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with TIA Section 312, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA Section 312(b).

SECTION 703. Reports by Trustee. Within 60 days after May 15 of each year commencing with the first May 15 after the Issue Date, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders (with a copy to the Company at the address specified in Section 106), in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports as required by the TIA Section 313(c).

(a) The Company may not consolidate or merge with or into or wind up into (whether or not the Company is the surviving entity), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless:

(1) the Company is the surviving company or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a Person organized or existing under the laws of the United States of America, any state thereof, the District of Columbia, or any territory thereof (the Company or such Person, as the case may be, being herein called the “Successor Company”); provided that if such Person is not a corporation, such Person immediately causes a Subsidiary that is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia to be added as a co-issuer of the Notes under this Indenture;

(2) the Successor Company, if other than the Company, expressly assumes all the obligations of the Company under this Indenture and the Notes pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee;

(4) immediately after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter period,

(A) the Successor Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 1011(a) of this Indenture or

(B) the Fixed Charge Coverage Ratio for the Successor Company and the Restricted Subsidiaries on a consolidated basis would be greater than such ratio for the Company and the Restricted Subsidiaries immediately prior to such transaction;

provided that this clause (4) shall be suspended during any period in which the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants;

(5) each Subsidiary Guarantor, unless it is the other party to the transactions described above, in which case Section 802(A)(2) shall apply, shall have by supplemental indenture confirmed that its Subsidiary Guarantee shall apply to such Person’s obligations under this Indenture and the Notes; and

(6) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indentures, if any, comply with this Indenture.

(1) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company and

(2) the Company may merge with an Affiliate of the Company incorporated solely for the purpose of reincorporating the Company in another State of the United States of America or converting into a different form of business entity so long as the amount of Indebtedness of the Company and the Restricted Subsidiaries is not increased thereby.

SECTION 802. Subsidiary Guarantors May Consolidate, Etc., Only on Certain Terms.

SECTION 903. Execution of Amendments, Supplements or Waivers. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article Nine 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, supplement or waiver until its Board of Directors approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive and shall be fully protected in relying upon, in addition to the documents required by Section 103 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

SECTION 906. Reference in Notes to Supplemental Indentures.

SECTION 907. 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 amendment, supplement or waiver becomes effective.

The Company shall pay interest on overdue principal at the rate equal to the then applicable interest rate on the Notes, and it shall pay interest on overdue installments of interest at the same rate, in any case to the extent lawful.

SECTION 1002. Maintenance of Office or Agency. The Company shall maintain an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Corporate Trust Office of the Trustee shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company shall give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

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 any such designation. The Company shall give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 1003. Paying Agent to Hold Money in Trust. If the Company shall at any time act as their own Paying Agent, it shall, on or before each due date of the principal of (or premium, if any) or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto an amount of cash sufficient to pay the principal of (or premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for the Notes, it shall, on or before each due date of the principal of (or premium, if any) or interest on any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of such action or any failure so to act.

The Company shall cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

(1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee notice of any Default by the Company (or any other obligor upon the Notes) in the making of any payment of principal (and premium, if any) or interest; and

(3) at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Subject to applicable laws relating to abandoned property, 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 (or premium, if any) or interest on any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, 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, shall thereupon cease.

SECTION 1004. Corporate Existence. Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence and that of each Restricted Subsidiary and the corporate rights (charter and statutory) and franchises of the Company and each Restricted Subsidiary; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole.

SECTION 1005. Taxes. The Company shall pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

(a) The Company shall deliver to the Trustee within 120 days after the end of each fiscal year, an Officer’s Certificate stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether it has kept, observed, performed and fulfilled, and has caused each of its Restricted Subsidiaries to keep, observe, perform and fulfill its obligations under this Indenture and further stating, as to each such Officer signing such certificate, that, to the best of his or her knowledge, the Company during such preceding fiscal year has kept, observed, performed and fulfilled, and has caused each of its Restricted Subsidiaries to keep, observe, perform and fulfill each and every such covenant contained in this Indenture and no Default occurred during such year and at the date of such certificate there is no Default which has occurred and is continuing or, if such signers do know of such Default that is continuing, the certificate shall describe such Default and what action each is taking or proposes to take with respect thereto and that, to the best of his or her knowledge, no event has occurred and remains by reason of which payments on the account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event. The Officer’s Certificate shall also notify the Trustee should the Company elect to change the manner in which it fixes its fiscal year-end. For purposes of this Section 1008(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) So long as any Notes are Outstanding, the Company will deliver to the Trustee, forthwith upon any Officer becoming aware of any Default, an Officer’s Certificate specifying such Default and what action the Company is taking or proposes to take with respect thereto.

(c) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates delivered under this Indenture).

(d) Notwithstanding the foregoing, the Company shall be deemed to have furnished such reports referred to above to the Trustee and Holders if the Company has filed such reports with the SEC via the EDGAR filing system (or any successor system) or, if the Company is not subject to reporting under Section 13 or 15(d) of the Exchange Act and are not permitted to file such reports with the SEC, if the Company posts such reports on its publicly available website.

(f) The principal amount of any Indebtedness incurred to extend, replace, refund, refinance, renew or defease other Indebtedness, if incurred in a different currency from the Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance.

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such obligations that would be payable by such Person at such time;

(3) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

SECTION 1012. Liens. The Company shall not, and shall not permit any of the Subsidiary Guarantors to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures obligations under any Indebtedness on any asset or property of the Company or any Subsidiary Guarantor now owned or hereafter acquired, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless:

(1) in the case of Liens securing Subordinated Indebtedness, the Notes or the applicable Subsidiary Guarantee of a Subsidiary Guarantor, as the case may be, are secured by a Lien on such property or assets that is senior in priority to such Liens; and

(2) in all other cases, the Notes or the applicable Subsidiary Guarantee of a Subsidiary Guarantor, as the case may be, are equally and ratably secured;

provided that any Lien that is granted to secure the Notes under this Section 1012 shall be discharged at the same time as the discharge of the Lien that gave rise to the obligation to so secure the Notes.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10.0 million, unless

(1) such Affiliate Transaction (taken as a whole, in the case of a series or group of related transactions, whether or not occurring substantially simultaneously) is on terms that are not materially 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

(2) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $50.0 million, a Board Resolution adopted by the majority of the members of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) above.

(7) the existence of, or the performance by the Company or any of the Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement or its equivalent (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Company or any Restricted Subsidiary of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (7) to the extent that the terms of any such existing agreement together with all amendments thereto, taken as a whole, or new agreement are not disadvantageous to the Holders in any material respect as compared to the terms of the original agreement as in effect on the Issue Date as reasonably determined in good faith by the Company;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture that are fair to the Company and the Restricted Subsidiaries, in the reasonable determination of the Board of Directors or the senior management of the Company, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

SECTION 1014. Limitations on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary that is not a Subsidiary Guarantor to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any such Restricted Subsidiary to:

(b) make loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of, or a requirement to subordinate, loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

except (in each case) for such encumbrances or restrictions existing under or by reason of:

(2) this Indenture and the Notes and the Subsidiary Guarantees of the Notes issued hereunder;

(3) purchase money obligations for property acquired and Capitalized Lease Obligations that impose restrictions of the nature discussed in clause (c) above on the property so acquired and other Liens permitted to be incurred under Section 1012 that limit the right of the debtor to dispose of the assets subject to such Liens;

SECTION 1016. Limitation on Sale and Lease-Back Transactions. The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction with respect to any property unless:

accrued and unpaid interest, to, but not including, the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company shall send notice of such Change of Control Offer by first class mail or electronically, to each Holder to the address of such Holder appearing in the security register with a copy to the Trustee, with the following information:

(1) a description of the transaction or transactions and identification of the ratings decline that together constitute a Change of Control Triggering Event and stating that a Change of Control Offer is being made pursuant to this Section 1017, and that all Notes properly tendered pursuant to such Change of Control Offer shall be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 15 days nor later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) any Note not properly tendered shall remain outstanding and continue to accrue interest;

(4) 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 shall cease to accrue interest on the Change of Control Payment Date;

(5) Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall 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 specified in the notice 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;

(7) Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (which unpurchased portion must be equal to $2,000 or an integral multiple of $1,000 in excess of $2,000); provided that no Notes of less than $2,000 shall be redeemed in part.

(b) While the Notes are in global form and the Company makes an offer to purchase all of the Notes pursuant to the Change of Control Offer, a Holder may exercise its option to elect for the purchase of the Notes through the facilities of DTC, subject to its rules and regulations.

(c) The Company shall 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 or regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of this Indenture, or compliance with the Change of Control Triggering Event provisions of this Indenture would constitute a violation of any such law or regulation, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 1017 by virtue thereof.

(d) On the Change of Control Payment Date, the Company shall, to the extent permitted by law,

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

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

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate stating that such Notes or portions thereof have been tendered to and purchased by the Company.

(e) The Paying Agent shall promptly mail to each Holder the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail to each Holder a new Note equal in principal amount to the unpurchased portion of the Notes surrendered, if any; provided that no Notes of $2,000 or less shall be redeemed in part and each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(f) The Company shall not be required to make a Change of Control Offer following a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to Section 1105 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, conditional upon such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(g) In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Company (or the third party making the Change of Control Offer as described above) purchases all of the Notes held by such Holders, the Company shall have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding to, but not including, the date of redemption, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, cause, make or suffer to exist an Asset Sale (including any MLP Asset Transfer), unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Company) of the assets or Equity Interests sold or otherwise disposed of; and

(2) other than in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; provided that the amount of

(A) any liabilities (as shown on the Company’s most recent consolidated balance sheet or in the notes thereto) of the Company or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets (or a third party on behalf of the transferee) and for which the Company or such Restricted Subsidiary has been validly released by all relevant creditors in writing,

(B) any securities, notes or other obligations or assets received by the Company or such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received) within 180 days following the closing of such Asset Sale, and

(C) any Designated Noncash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (C) that is at that time outstanding, not to exceed the greater of (x) $75.0 million and (y) 4.0% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value,

shall be deemed to be cash for purposes of this provision and for no other purpose; provided, that in the case of an MLP Asset Transfer, in lieu of the requirement in clause (2), the Company, at its election, may meet the following requirements:

(A) after such MLP Asset Transfer and as a result thereof, (x) the Company and its Restricted Subsidiaries shall have received an amount of cash and Designated Noncash Consideration permitted by clause (c) above attributable to such MLP Asset Transfer (as a result of (i) the receipt of cash proceeds and Designated Noncash Consideration as all or a portion of the consideration for such MLP Asset Transfer or (ii) the repayment of intercompany indebtedness, owed by a Subsidiary of the Company, transferred or assumed as part of such MLP Asset Transfer) at least equal to 50% of the fair market value (as determined in good faith by the Company based on values that could be obtained in an arms’ length transaction) of (A) the assets and property transferred or (B) in the case of a transfer of any Equity Interests of a Person, such Person at the time of such MLP Asset Transfer (it being understood that, in the case of a transfer of less than all of the Equity Interests of a Person, the value of such Person shall be determined at the time of the first MLP Asset Transfer constituting part of such MLP Asset Transfer (as if all the Equity Interests in such Person were transferred at the time of such first MLP Asset Transfer, and the cash requirement set forth in this clause shall be satisfied on that basis in connection with such first MLP Asset Transfer) and there shall be no such additional cash attributable to such MLP Asset Transfer required for any subsequent transfer of Equity Interests of such Person constituting part of the MLP Asset Transfer) (in each case of the foregoing clauses (A) and (B), assuming such assets or

Person, as applicable, operates as a going concern), with the balance of the consideration received by the Company and its Restricted Subsidiaries for such MLP Asset Transfer consisting solely of Equity Interests in the applicable MLP and (y) immediately after giving effect to such MLP Asset Transfer on a pro forma basis, the Company could incur $1.00 of additional Indebtedness under the provisions of Section 1011(a); and

(B) no Default shall have occurred and be continuing or would occur as a consequence thereof.

For purposes of calculating the fair market value of any assets or property transferred to any Person, any Person and any Equity Interests in a Person with respect to any MLP Asset Transfer, any Indebtedness that is owed by such Person to the Company or any Restricted Subsidiary shall be disregarded and shall not be reflected in such calculation to reduce the fair market value of such assets or property, Person or Equity Interests in such Person, as the case may be.

(b) Within 365 days after any of the Company’s or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale (including any MLP Asset Transfer), the Company or such Restricted Subsidiary may, at its option, apply the Net Proceeds from such Asset Sale:

(x) Obligations under the Senior Credit Facility or any other Senior Indebtedness, in each case, of the Company or any Subsidiary Guarantor, and, in the case of Obligations under the Senior Credit Facility or other similar Indebtedness, to correspondingly permanently reduce commitments with respect thereto (other than Obligations owed to the Company or a Restricted Subsidiary); provided that if the Company or any Restricted Subsidiary shall so reduce Obligations under any Senior Indebtedness that is not Secured Indebtedness, the Company or such Restricted Subsidiary shall, equally and ratably, reduce Obligations under the Notes by, at its option, (A) redeeming Notes to the extent the Notes are then redeemable as provided by the terms of the Notes, (B) making an offer (in accordance with the procedures set forth in this Section 1018) to all Holders to purchase their Notes at 100% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date or (C) purchasing Notes through open market purchases (to the extent such purchases are at a price equal to or higher than 100% of the principal amount thereof) in a manner that complies with this Indenture and applicable securities law; or

(y) Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor, other than Indebtedness owed to the Company or another Restricted Subsidiary; or

(2) to an investment in (A) any one or more businesses; provided that such investment in any business is in the form of the acquisition of Capital Stock and results in the Company or any Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) properties, (C) capital expenditures and (D) acquisitions of other assets, that in each of (A), (B), (C) and (D), are used or useful in a Similar Business or replace the businesses, properties and assets that are the subject of such Asset Sale.

(c) Any Net Proceeds from any Asset Sale that are not invested or applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Proceeds shall be deemed to constitute “Excess Proceeds;” provided that if during such 365-day period the Company or a

Restricted Subsidiary enters into a definitive binding agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2) of Section 1018(b) after such 365th day, such 365-day period shall be extended with respect to the amount of Net Proceeds so committed, but such extension shall in no event be for a period longer than 180 days, until such Net Proceeds are required to be applied in accordance with such agreement (or, if such agreement is terminated before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds from and after the date of such termination). When the aggregate amount of such Excess Proceeds exceeds $25.0 million, the Company shall make an offer to all Holders and, if required by the terms of any Senior Indebtedness, to the holders of such other Senior Indebtedness (other than with respect to Hedging Obligations) (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of Notes and such other Senior Indebtedness that is an integral multiple of $1,000 (subject to any required minimum denominations) that may be purchased out of such Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Company shall commence an Asset Sale Offer with respect to such Excess Proceeds within ten Business Days after the date that such Excess Proceeds exceed $25.0 million by mailing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to such Net Proceeds prior to the expiration of the relevant 365 days (or such longer period provided above) or with respect to Excess Proceeds of $25.0 million or less. To the extent that the aggregate amount of Notes and such other Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for any purpose not prohibited by this Indenture. Subject to Section 1018(f), if the aggregate principal amount of Notes and other Senior Indebtedness surrendered by the holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select or cause to be selected the Notes and the Company or agent for such other Senior Indebtedness shall select such other Senior Indebtedness to be purchased on a pro rata basis based on the principal amount (or accreted value, if applicable) of the Notes or such other Senior Indebtedness tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds related to such Asset Sale Offer shall be reset at zero.

(d) Pending the final application of any Net Proceeds pursuant to this Section 1018, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(e) The Company shall 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 or regulations are applicable in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 1018, or compliance with the Section 1018 would constitute a violation of any such laws or regulations, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the provisions of this Section 1018, as applicable, by virtue thereof.

(f) If the Company is repurchasing less than all of the Notes at any time, the Trustee shall select the Notes to be repurchased (a) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which such Notes are listed or (b) if such Notes are not so listed, on a pro rata basis or by lot or by such other method as may be required by the procedures of DTC; provided that no Notes of $2,000 or less shall be repurchased in part.

(g) Notices of repurchase shall be mailed by first class mail, postage prepaid, at least 15 days but not more than 60 days before the date of repurchase to each Holder at such Holder’s registered address, except that notices of repurchase may be mailed more than 60 days prior to a date of repurchase if

the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. If any Note is to be repurchased in part only, any notice of repurchase that relates to such Note shall state the portion of the principal amount thereof to be repurchased.

(h) A new Note in principal amount equal to the unrepurchased portion of any Note repurchased in part shall be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for repurchase become due and payable on the date fixed for repurchase. On and after the date of repurchase, unless the Company defaults in the repurchase payment, interest shall cease to accrue on the Note or portions thereof called for repurchase.

SECTION 1020. Additional Interest Notice. In the event that the Company is required to pay Additional Interest to Holders pursuant to the Registration Rights Agreement, the Company shall provide written notice (an “Additional Interest Notice”) to the Trustee of their obligation to pay Additional Interest no later than fifteen days prior to the proposed payment date for the Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

(a) During any period when the Notes have an Investment Grade Rating from both Rating Agencies and no Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries will not be subject to the provisions of Sections 801(a)(4), 1010, 1011, 1013, 1014, 1016 (only to the extent set forth in Section 1016) and 1018 (collectively, the “Suspended Covenants”); provided that the provisions of Article Eight (except with respect to Section 801(a)(4)), Section 1009, 1012, 1015, 1016 (except to the extent set forth in such Section 1016) and 1017 will not be so suspended; and provided further, that if the Company and our Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding portion of this sentence and, subsequently, either of the Rating Agencies withdraws its ratings or downgrades the ratings assigned to the Notes below the Investment Grade Ratings so that the Notes do not have an Investment Grade Rating from both Rating Agencies, or a Default (other than with respect to the Suspended Covenants) occurs and is continuing, the Company and Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants, subject to the terms, conditions and obligations set forth in this Indenture (each such date of reinstatement being the “Reinstatement Date”).

(b) Compliance with the Suspended Covenants with respect to Restricted Payments made after the Reinstatement Date will be calculated in accordance with the terms of Section 1010 as though such covenants had been in effect during the entire period of time from which the Notes are issued. However, all Restricted Payments made, Indebtedness incurred and other actions effected during any period in which covenants are suspended will not cause a default under this Indenture on any Reinstatement Date.

(c) In addition, during any period when the Suspended Covenants are suspended, the Company shall not be permitted to designate or redesignate any of our Subsidiaries as described under the definition of “Unrestricted Subsidiary.”

(d) The Company, in an Officer’s Certificate, shall promptly provide notice to the Trustee of any occurrence of any period of time when the Company is not subject to the Suspended Covenants and of any Reinstatement Date. The Trustee shall have no obligation to (i) independently determine or verify if such events have occurred, (ii) make any determination regarding the impact of actions taken during any period of time when the Company is not subject to the Suspended Covenants or the Company’s future compliance with any covenants, or (iii) notify the holders of any period of time when the Company is not subject to the Suspended Covenants or of any Reinstatement Date.

(a) At any time prior to June 15, 2016, the Company may redeem all or a part of the Notes, upon not less than 15 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, to, but not including, the applicable Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date.

(b) From and after June 15, 2016, the Company may redeem the Notes, in whole or in part, upon not less than 15 nor more than 60 days’ prior notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to, but not including, the applicable Redemption Date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on June 15 of each of the years indicated below:

(c) Prior to June 15, 2016, the Company may, at its option, on one or more occasions, redeem up to 35% of the sum of the original aggregate principal amount of Notes (and the original principal amount of any Additional Notes) issued under this Indenture at a redemption price equal to 107.500% of the aggregate principal amount thereof, plus accrued and unpaid interest to, but not including, the applicable Redemption Date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, with the net cash proceeds of one or more Equity Offerings of the Company or any direct or indirect parent of the Company to the extent such net cash proceeds are contributed to the Company; provided that at least 65% of the sum of the aggregate principal amount of Notes originally issued under this Indenture and the original principal amount of any Additional Notes issued under this Indenture after the Issue Date remains Outstanding immediately after the occurrence of each such redemption; provided, further, that each such redemption occurs within 90 days of the date of closing of each such Equity Offering.

SECTION 1102. Applicability of Article. Redemption of Notes at the election of the Company or otherwise, as permitted or required by any provision of this Indenture or the Notes, shall be made in accordance with such provision and this Article.

SECTION 1103. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Notes pursuant to Section 1101 above shall be evidenced by a Board Resolution of the Board of Directors of the Company. If the Company elects to redeem Notes pursuant to Section 1101 hereof, it shall furnish to the Trustee, at least five Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to Section 1105 hereof, an Officer’s Certificate setting forth (i) the paragraph or subparagraph of such Note and/or Section of this Indenture pursuant to which the redemption shall occur, (ii) the Redemption Date, (iii) the principal amount of the Notes to be redeemed and (iv) the Redemption Price.

(a) If the Company is redeeming less than all of the Notes at any time, the Trustee shall select the Notes to be redeemed (a) if the Notes are listed on any national securities exchange (and such listing is known to the Trustee), in compliance with the requirements of the principal national securities exchange on which such Notes are listed or (b) if such Notes are not so listed, on a pro rata basis to the extent practicable or by lot or by such other method as may be required by the procedures of DTC; provided that no Notes of $2,000 or less shall be redeemed in part.

(b) If any Note is to be redeemed in part only, any notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

(c) A new Note in principal amount equal to the unredeemed portion of any Note redeemed in part shall be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due and payable on the date fixed for redemption. On and after the Redemption Date, unless the Company defaults in the redemption payment, interest shall cease to accrue on the Note or portions thereof called for redemption.

SECTION 1105. Notice of Redemption. Notices of redemption shall be sent electronically or be mailed by first class mail, postage prepaid, at least 15 days but not more than 60 days before the Redemption Date to each Holder at such Holder’s registered address, except that notices of redemption may be sent electronically or mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture.

(2) the Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 1107, if any,

(4) in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on and after the Redemption Date, upon surrender of such Note, the Holder shall receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that on the Redemption Date the Redemption Price (and accrued interest, if any, to the Redemption Date payable as provided in Section 1107) shall become due and payable upon each such Note, or the portion thereof, to be redeemed, and that interest thereon shall cease to accrue on and after said date,

(6) the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if any,

(8) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price,

(9) 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,

(11) the paragraph of the Notes or Section of this Indenture pursuant to which the Notes are to be redeemed.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided that the Company shall have delivered to the Trustee, at least five Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this Section 1105 (unless a shorter notice shall be agreed to by the Trustee), an Officer’s Certificate from the Company requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 1103 and this Section 1105.

SECTION 1106. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 1105 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the Redemption Price. The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 1107 hereof, on and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption.

SECTION 1107. Deposit of Redemption Price. Prior to 10:00 a.m. (Eastern Time) on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest and Additional Interest, if any, on, all the Notes that are to be redeemed on that date. The Trustee or the Paying Agent shall 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 price of, and accrued and unpaid interest and Additional Interest, if any, on, all Notes to be redeemed or purchased. If the Company complies with the provisions of this Section 1107, on and after the Redemption Date, interest will cease to accrue on the Notes or the portions of Notes called for redemption.

(a) Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued interest and Additional Interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price, together with accrued interest and Additional Interest, if any, to, but not including, the applicable Redemption Date and such Notes shall be canceled by the Trustee; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant record dates according to their terms and the provisions of Section 306.

(b) If any Note called for redemption shall not be so paid upon surrender thereof for redemption because of the failure of the Company to comply with Section 1108(a), the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes.

SECTION 1109. Notes Redeemed in Part. Any Note which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 1002 (with, if the Company or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered; provided that no Note of $2,000 or less will be redeemed in part.

SECTION 1201. Subsidiary Guarantees. Each Subsidiary Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees, as primary obligor and not merely as surety, the Notes and obligations of the Company hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee, and to the Trustee for itself and on behalf of such Holder, that: (1) the principal of (and premium, if any) and interest on, or Additional Interest in respect of, the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including the amount that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise, subject, however, in the case of clauses (1) and (2) above, to the limitation set forth in Section 1204 hereof.

(a) Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, any release of any other Subsidiary Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor.

(b) Each Subsidiary Guarantor hereby waives (to the extent permitted by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands whatsoever and covenants that the Subsidiary Guarantee of such Subsidiary Guarantor shall not be discharged as to any Note except by complete performance of the obligations contained in such Note, this Indenture and such Subsidiary Guarantee. Each Subsidiary Guarantor acknowledges that the Subsidiary Guarantee is a guarantee of payment, performance and compliance when due and not of collection. Each of the Subsidiary Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest on such Note, whether at its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Subsidiary Guarantors to enforce such Subsidiary Guarantor’s Subsidiary Guarantee without first proceeding against the Company or any other Subsidiary Guarantor.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company or any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or any Subsidiary Guarantor, any amount paid by any of them to the Trustee or such Holder, the Subsidiary Guarantee of each of the Subsidiary Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor further agrees that, as between each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee on the other hand, (1) subject to this Article Twelve, the Maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of the Subsidiary Guarantee of such Subsidiary Guarantor notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any acceleration of such obligation as provided in Article Five hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of the Subsidiary Guarantee of such Subsidiary Guarantor. The Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

(d) Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation, reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

SECTION 1202. Severability. In case any provision of any Subsidiary Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby to the extent permitted by applicable law.

SECTION 1207. Reinstatement. Each Subsidiary Guarantor hereby agrees (and each Person who becomes a Subsidiary Guarantor shall agree) that the Subsidiary Guarantee provided for in Section 1201 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the Company upon the bankruptcy or insolvency of the Company or any Subsidiary Guarantor.

(2) in the case of clause (1)(A) above, the release or discharge of such Subsidiary Guarantor from its guarantee, if any, of and all pledges and security, if any, granted in connection with, the Senior Credit Facility and any other Indebtedness of the Company or any Restricted Subsidiary.

SECTION 1302. Legal Defeasance and Discharge. Upon the Company’s exercise under Section 1301 of the option applicable to this Section 1302, each of the Company and the Subsidiary Guarantors shall be deemed to have been discharged from its respective obligations with respect to all Outstanding Notes on the date the conditions set forth in Section 1304 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that each of the Company and the Subsidiary Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1305 and the other Sections of this Indenture referred to in (1) and (2) below, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes and their related Subsidiary Guarantees are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder:

For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company or any Subsidiary Guarantor, as applicable, may omit to comply with and shall 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 shall not constitute a Default or an Event of Default.

(4) no Default (other than that resulting from borrowing funds to be applied to make such deposit (and any similar concurrent depositing relating to other Indebtedness, or a Default or Event of Default that will be cured by such Covenant Defeasance or Legal Defeasance) and the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any of the Senior Credit Facility, or any other material agreement or instrument (other than this Indenture) to which, the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound;

(6) the Company shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or any Subsidiary Guarantor or others; and

The Company shall pay and indemnify the Qualifying Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes.

Anything in this Article Thirteen to the contrary notwithstanding, the Qualifying Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided in Section 1304 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Qualifying Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this Article.

SECTION 1306. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with Section 1305 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and each Subsidiary Guarantor’s obligations under this Indenture and the Outstanding Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1305; provided, however, that if the Company makes any payment of principal of (or premium, if any) or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

SECTION 1307. Repayment to Company.

(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 Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Permanent Regulation S Global Note (in the case of a transfer pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase,

Regulation S Global Note, as applicable, to be increased by the aggregate principal amount of the Certificated Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, equal to the principal amount of the Certificated Note so canceled.

(i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Note Registrar a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Note. The Note Registrar shall, in accordance with such instructions instruct the Depository 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 the beneficial interest in the Global Note being transferred.

AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

Each certificate evidencing a Note offered in reliance on Regulation S shall, in addition to the foregoing, bear a legend in substantially the following form:

The Company promises to pay interest and Additional Interest, if any, on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate of 7.50% per annum (subject to adjustment as provided below).

Interest, and Additional Interest, if any, shall be payable semi-annually (to the Holders of the Notes at the close of business on June 1 or December 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing December 15, 2013.

The Holder of this Note is entitled to the benefits of the Registration Rights Agreement, dated June 14, 2013, among the Company, the Subsidiary Guarantors and Citigroup Global Markets Inc., as representative of the several Initial Purchasers (the “Registration Rights Agreement”), including with respect to Additional Interest.

Interest, including Additional Interest, if any, on this Note shall accrue from the most recent date to which interest has been paid on this Note or the Note surrendered in exchange herefor or, if no interest has been paid, from June 14, 2013; provided that, if there is no existing Default in the payment of interest and if this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

The Company shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest and Additional Interest, if any, to the extent lawful, at a rate per annum equal to the rate of interest applicable to the Notes.

However, the Company may pay principal (premium, if any) and interest by their check payable in such money. The Company may pay interest on the Notes either (a) by mailing a check for such interest to a Holder’s registered address (as reflected in the Note Register) or (b) by wire transfer to an account located in the United States maintained by the payee. If a payment date is a date other than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

Initially, Wilmington Trust, National Association (the “Trustee”), shall act as Paying Agent and Note Registrar. The Company may change any Paying Agent or Note Registrar upon written notice thereto and without notice to the Holders. The Company, any Subsidiary or any Affiliate of any of them may act as Paying Agent, Note Registrar or co-registrar.

The Company issued the Notes under an Indenture dated as of June 14, 2013 (the “Indenture”), among the Company, the Subsidiary Guarantors 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 Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

The Notes are unsecured senior obligations of the Company. The Indenture does not limit the aggregate principal amount of the Notes. Subject to the conditions set forth in the Indenture, the Company may issue Additional Notes.

At any time prior to June 15, 2016, the Company may redeem all or a part of the Notes, upon not less than 15 nor more than 60 days’ prior notice at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but not including, the applicable Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date.

On and after June 15, 2016, the Company may redeem the Notes, in whole or in part, upon not less than 15 nor more than 60 days’ prior notice to each Holder at the Redemption Prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to, but not including, the applicable Redemption Date, subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on June 15 of each of the years indicated below:

the Company or any direct or indirect parent of the Company to the extent such net cash proceeds are contributed to the Company; provided that at least 65% of the sum of the aggregate principal amount of Notes originally issued under the Indenture and the original principal amount of any Additional Notes issued under the Indenture after the Issue Date remains Outstanding immediately after the occurrence of each such redemption; provided, further, that each such redemption occurs within 90 days of the date of closing of each such Equity Offering.

Upon the occurrence of (a) a Change of Control Triggering Event, the Company will be required to make an offer to purchase such Holder’s outstanding Notes, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the date of purchase and (b) Asset Sales, the Company may be obligated to make offers to purchase Notes and Senior Indebtedness of the Company with a portion of the Net Proceeds of such Asset Sales at a redemption price of 100% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date of purchase.

The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. The Note 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 Note Registrar need not register the transfer or exchange of a Note or portion of a Note selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Note or portion of a Note for a period of 15 days before a selection of Notes to be redeemed or 15 days before an Interest Payment Date.

Subject to any laws relating to abandoned property, if money for the payment of principal (premium, if any) or interest remains unclaimed for two years, the Trustee and the Paying Agent shall pay the money back to the Company on Company Request or (if then held by the Company) shall be discharged from such trust. After that, Holders entitled to the money must look to the Company for payment and all liability of the Trustee and such Paying Agent with respect to such money, and all liability of the Company as trustee thereof, shall cease.

Subject to satisfaction of conditions set forth in the Indenture, the Company at any time may terminate some or all of their obligations under the Notes and the Indenture if the Company irrevocably deposits with the Trustee cash or Government Securities or a combination thereof sufficient for the payment of the then outstanding principal of and interest on the Notes to Redemption or Stated Maturity, as the case may be.

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 Outstanding Notes, including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the 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 Outstanding Notes. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, omission, mistake, defect or inconsistency and make any change that does not adversely affect the legal rights of any Holder.

The Indenture contains certain covenants, including covenants with respect to the following matters: (i) Restricted Payments; (ii) incurrence of Indebtedness and issuance of Disqualified Stock and Preferred Stock; (iii) Liens; (iv) transactions with Affiliates; (v) dividend and other payment restrictions affecting Restricted Subsidiaries; (vi) future Subsidiary Guarantors; (vii) reports and other information; (viii) merger, consolidation or sale of all or substantially all assets; (ix) purchase of Notes upon a Change of Control Triggering Event; (x) sale and lease-back transactions and (xi) disposition of proceeds of Asset Sales. Within 120 days (or the successor time period then in effect under the rules and regulations of the Exchange Act) after the end of each fiscal year, the Company must report to the Trustee on compliance with such limitations.

When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person shall be released from those obligations, subject to certain exceptions.

If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes may declare all Outstanding Notes to be immediately due and payable. If an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company or any Significant Subsidiary occurs and is continuing, the Notes automatically become immediately due and payable. Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense. Subject to certain restrictions, the Holders of a majority in principal amount of the Outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability.

The Company’s obligations under the Notes are fully, irrevocably and unconditionally guaranteed on an unsecured senior basis, to the extent set forth in the Indenture, by each of the Subsidiary Guarantors.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for, and otherwise deal with, the Company and any of its Affiliates as if it were not the Trustee.

This Note shall not be valid until the Trustee manually signs the certificate of authentication on the other side of this Note.

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).

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 has directed the Trustee to 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 that reliance may be placed only on the serial or other identification numbers placed thereon.

Each Holder of a Note, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of , 201 , among (the “Guaranteeing Subsidiary”), a subsidiary of SemGroup Corporation (or its permitted successor), a Delaware corporation (the “Company”), the other Subsidiary Guarantors (as defined in the Indenture referred to herein) and Wilmington Trust, National Association, as trustee under the Indenture referred to below (the “Trustee”).

WHEREAS, the Company has heretofore executed and delivered to the Trustee a senior unsecured indenture (the “Indenture”), dated as of June 14, 2013 providing for the issuance of 7.50% Senior Notes Due 2021 (the “Notes”);

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

WHEREAS, pursuant to Section 901 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. AGREEMENT TO SUBSIDIARY GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Subsidiary Guarantee on the terms and subject to the conditions set forth in the Note Subsidiary Guarantee and in the Indenture including but not limited to Article 12 thereof.

3. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation; provided that the foregoing shall not limit any of the Company’s obligations under the Notes. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

5. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

6. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.

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

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