THE NOTES

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A1 or Exhibit A2 hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibits A1 or A2 attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A1 attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto).

Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Paying Agent, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, at its corporate trust office, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

Following the termination of the Restricted Period, the Trustee will remove the Regulation S Temporary Global Note Legend from the Regulation S Temporary Global Note, following which temporary beneficial interests in the Regulation S Temporary Global Note shall automatically become beneficial interests in Regulation S Permanent Global Notes pursuant to the Applicable Procedures. The aggregate principal amount of each Regulation S Temporary Global Note and the respective Regulation S Permanent Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

(d) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

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

The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate Notes for original issue. In addition, at any time, from time to time, the Trustee shall upon receipt of an Authentication Order authenticate and deliver Additional Notes in one or more series for original issue in aggregate principal amounts specified by the Company.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.03 Registrar and Paying Agent.

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

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. Neither the Trustee nor any agent thereof shall have any responsibility or liability for any actions taken or not taken by the Depositary.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent for the Notes and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

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

Section 2.05 Holder Lists.

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

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if:

(1) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 120 days after the date of such notice from the Depositary;

(2) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Definitive Notes prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

(3) requested by a holder, and there has occurred and is continuing a Default or an Event of Default.

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); provided, however, that beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1) Transfer of Beneficial Interests in the Same Global Note.

Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

Any Notes that remain outstanding after the consummation of the Exchange Offer, and Exchange Notes issued in connection with the Exchange Offer, shall be treated as a single class of securities under this Indenture.

“THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON.”

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(i) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

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

(5) Neither the Registrar nor the Company will be required:

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Notes under Section 3.02 hereof and ending at the close of business on the day of such mailing;

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

(7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

(8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

Each Holder of a Note agrees to indemnify the Company, the Guarantor, the Registrar and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law, except to the extent such liability results from the willful misconduct or gross negligence of any such Person.

Neither the Trustee nor the Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depository Participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence in writing to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced and subsequently presented or claimed for payment. The Company may charge for its expenses in replacing a Note including reasonable fees and expenses of its counsel and of the Trustee and its counsel.

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

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Sections 3.07(b) hereof.

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

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

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

Section 2.09 Treasury Notes.

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

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes in accordance

with its customary procedures (subject to the record retention requirement of the Exchange Act). Certification of the cancellation of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

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

Section 2.13 CUSIP Numbers.

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

Section 2.14 Issuance of Additional Notes.

The Issuer shall be entitled, subject to their compliance with Sections 4.09 and 4.12 hereof, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the date hereof, other than with respect to the date of issuance, issue price and rights under a related registration rights agreement, if any. The Initial Notes issued on the date hereof and any Additional Notes and all Exchange Notes issued in exchange therefor shall be treated as a single class for all purposes under this Indenture, including directions, waivers, amendments, consents, redemptions and offers to purchase.

With respect to any Additional Notes, the Issuer shall set forth in a Board Resolution and an Officer’s Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

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

(ii) the issue price, the issue date and the CUSIP and/or ISIN number of such Additional Notes, provided, however, that no Additional Notes may be issued at price that would cause such Additional Notes to have original issue discount within the meaning of Section 1273 of the Code, other than a de minimis original issue discount within the meaning of Section 1273 of the Code; and

(iii) whether such Additional Notes shall be subject to the restrictions on transfer set forth in Section 2.06 relating to Restricted Global Notes and Restricted Definitive Notes.

ARTICLE 3
REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officer’s Certificate setting forth:

(1) the clause of this Indenture pursuant to which the redemption shall occur;

(2) the redemption date;

(3) the principal amount of Notes to be redeemed; and

(4) the redemption price.

Any optional redemption referenced in such Officer’s Certificate may be cancelled by the Company at any time prior to a notice of redemption being mailed to any Holder and, thereafter, shall be null and void.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed at any time or purchased in an offer to purchase, the Trustee will select such Notes for redemption or purchase as follows:

(1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

(2) if the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate.

No Notes of $2,000 or less can be redeemed in part (in each case in aggregate principal amount). In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or integral multiples of $1,000 in excess thereof (in each case in aggregate principal amount); except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, or send electronically in “pdf” format a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or Article 11 of this Indenture. Failure to give notice of redemption, or any defect therein, to any Holder of any Note selected for redemption shall not impair or affect the validity of the redemption of any other Note.

The notice will identify the Notes to be redeemed and will state:

(1) the redemption date;

(2) the redemption price;

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued (unless such unredeemed portion is equal to or less than $2,000 in principal amount) or transferred by book-entry upon cancellation of the original Note;

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

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

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

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

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

The Company may provide in the notice that payment of the redemption price and the performance of the Company’s obligations with respect to such redemption may be performed by another Person.

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

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed or sent electronically in “pdf” format in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. The notice, if sent in a manner herein provide, 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. Other than as expressly permitted herein, notices of redemption may not be conditional. On and after the redemption date, interest and Special Interest, if any, ceases to accrue on Notes or portions of them called for redemption.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest and Special Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly, and in any event within two Business Days after the redemption or purchase date, return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest and Special Interest, if any, on, all Notes to be redeemed or purchased.

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

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Definitive Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Definitive Note equal in principal amount to the unredeemed or unpurchased portion of the Definitive Note surrendered; provided that each new Definitive Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

Section 3.07 Optional Redemption.

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

The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made in accordance with Section 4.01 hereof.

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

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

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

(5) Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased only in integral multiples of $1,000 above $2,000 (in aggregate principal amount);

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

(7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer

Period, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

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

(9) that Holders whose Definitive Notes were purchased only in part will be issued new Definitive Notes equal in principal amount to the unpurchased (to the extent such unpurchased portion of the Definitive Notes is equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) portion of the Definitive Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order from the Company will authenticate and mail or deliver (or cause to be transferred by book-entry) such new Definitive Note to such Holder, in a principal amount equal to any unpurchased portion of the Definitive Note surrendered; provided that each such new Definitive Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Definitive Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

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

(1) the incurrence by the Company and any Restricted Subsidiary of the Company of Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (A) the sum of (x) $235.0 million and (y) $50.0 million or (B) the amount of the Borrowing Base on the date of such incurrence;

(2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Company of Indebtedness represented by the Notes and the Subsidiary Guarantees to be issued on the Issue Date and the Exchange Notes and the Subsidiary Guarantees to be issued pursuant to the Registration Rights Agreement;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, together with any Permitted Refinancing Indebtedness in respect thereof, not to exceed at any time outstanding the greater of (x) $50.0 million and (y) 5.0% of Consolidated Total Assets of the Company;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance, replace, defease or discharge Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (3), (4), (5), (12), (13) or (14) of this Section 4.09(b);

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

(A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due

with respect to the Notes, in the case of the Company, or the Subsidiary Guarantee, in the case of a Guarantor; and

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

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares of Preferred Stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(B) any sale or transfer of any such Preferred Stock to a Person that is not either the Company or a Restricted Subsidiary of the Company;

will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business;

(9) the guarantee (A) by the Company or any of the Subsidiary Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to the Notes, then the guarantee shall be subordinated to the same extent as the Indebtedness guaranteed and (B) by any Restricted Subsidiary that is not a Subsidiary Guarantor of Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor;

(10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance, completion and surety bonds or guarantees, and similar types of obligations in the ordinary course of business;

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness consisting of guarantees, earn-outs, indemnities or obligations in respect of purchase price adjustments in connection with the acquisition or disposition of assets, including, without limitation, shares of Capital Stock;

(13) (A) Indebtedness or Preferred Stock of a Person incurred and outstanding on or prior to the date on which such Person was acquired by the Company or any Restricted Subsidiary

of the Company or merged into the Company or a Restricted Subsidiary of the Company in accordance with the terms of this Indenture, (B) Indebtedness of the Company or any Restricted Subsidiary incurred or issued to finance an acquisition; provided, that, in the case of subclauses (A) and (B), after giving effect to such acquisition or merger and the incurrence of Indebtedness either (i) the 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 4.09(a) or (ii) such Fixed Charge Coverage Ratio would be equal to or greater than immediately prior to such acquisition;

(14) the incurrence by the Company or any of its Restricted Subsidiaries of (A) Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations incurred and outstanding on or prior to the date on which such Person was acquired by the Company or any Restricted Subsidiary of the Company or merged into the Company or a Restricted Subsidiary of the Company in accordance with the terms of this Indenture and (B) Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations in respect of assets replacing those financed by Indebtedness incurred in reliance on subclause (A); provided that such Indebtedness is not incurred in connection with or in contemplation of, or to provide all or any portion of the funds or credit support utilized to consummate, such acquisition or merger;

(15) the incurrence by the Company of Indebtedness in an aggregate principal amount which will not exceed 100% of the net cash proceeds received by the Company from the issuance or sale (other than to a Restricted Subsidiary) of its Capital Stock (other than Preferred Stock, Disqualified Stock or an Excluded Contribution) or otherwise contributed to the equity (other than through the issuance of Preferred Stock, Disqualified Stock or an Excluded Contribution) of the Company, in each case, subsequent to the Issue Date; provided, however, that (A) any such net cash proceeds that are so received or contributed shall not increase the amount available for making Restricted Payments to the extent the Company and its Restricted Subsidiaries incur Indebtedness in reliance thereon, (B) any net cash proceeds that are so received or contributed shall be excluded for purposes of incurring Indebtedness pursuant to this clause to the extent the Company or any of its Restricted Subsidiaries makes a Restricted Payment and (C) such Indebtedness pursuant to this clause (15) is incurred within 180 days after the date of such issuance or cash contribution;

(16) the incurrence by any Restricted Subsidiary that is not a Subsidiary Guarantor of Indebtedness or issuance thereby of shares of Preferred Stock or Disqualified Stock in an aggregate principal amount not to exceed $25.0 million at any one time outstanding; and

(17) the incurrence by the Company or any Restricted Subsidiary of the Company of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed the greater of (x) $50.0 million and (y) 5.0% of Consolidated Total Assets of the Company.

The Company will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Subsidiary Guarantee on substantially identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company or any Guarantor, as applicable, solely by virtue of being unsecured or by virtue of being secured on a first, second or third priority Lien basis or by virtue of

the fact that the holders of any secured Indebtedness have entered into intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness or portion thereof meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) above, or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted to classify such item of Indebtedness or portion thereof on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness or portion thereof, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the Issue Date will initially be deemed to have been incurred on such date in reliance on the exemption provided by clause (1) of the definition of Permitted Debt.

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

The amount of any Indebtedness outstanding as of any date will be:

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

(2) the principal amount of the Indebtedness (including any payment-in-kind Indebtedness), in the case of any other Indebtedness; and

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

(A) the Fair Market Value of such assets at the date of determination, and

(B) the amount of the Indebtedness of the other Person that is secured by such assets.

Section 4.10 Asset Sales.

The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

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

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash:

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

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

(D) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause that is at that time outstanding, not to exceed 5% of Consolidated Total Assets of the Company as of the end of the Company’s most recently ended fiscal quarter prior to the date on which such Designated Non-cash Consideration is received (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received without giving effect to subsequent changes in value), shall be deemed to be cash for purposes of this Section 4.10(2)(D) and for no other purpose.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds at its option:

(1) to retire Indebtedness constituting First Priority Lien Obligations (whether or not the assets that were subject to such Asset Sale constitute Collateral) and, if the Indebtedness retired is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2) to the extent such Net Proceeds are not from an Asset Sale of any Collateral, to retire Indebtedness secured by the assets that are the subject of such Asset Sale and, if the Indebtedness retired is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

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

(4) to make a capital expenditure; or

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

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

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of this Section 4.10 will constitute “Excess Proceeds,” provided that, if during such 365-day period the Company or a Restricted Subsidiary of the Company enters into a definitive written agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2), (3) or (4) of such paragraph, such 365-day period shall be extended with respect to the amount of Net Proceeds so committed until 180 days after the date of such commitment (or, if earlier, until termination of such agreement).

When the aggregate amount of Excess Proceeds exceeds $20.0 million, within five days thereof, the Company will make an offer to purchase (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest and Special Interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall select such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

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

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

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors of the Company set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by (x) a majority of the disinterested members of

the Board of Directors or (y) in the event there are no disinterested members of the Board of Directors, a majority of the members of the Board of Directors; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $30.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing; provided, however, that the aforementioned opinion will not be required in the case of any issuance of Disqualified Stock that is subject to this Section 4.11(a).

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

(1) compensation arrangements, any employment agreement, employee benefit plan, officer and director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business;

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

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

(4) so long as they comply with clause (1) of Section 4.11(a), transactions with customers, clients, lessors, landlords, suppliers, contractors, or purchasers or sellers of goods or services that are Affiliates, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture;

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

(6) any issuance of Equity Interests (other than Disqualified Stock);

(7) Restricted Payments that do not violate Section 4.07 hereof and Permitted Investments;

(8) loans or advances to employees in the ordinary course of business not to exceed $1.5 million in the aggregate at any one time outstanding;

(9) the agreements described in the “Certain Relationships and Related Party Transactions” section of the Company’s Offering Memorandum, dated July 24, 2012, relating to the offering of the Initial Notes, as in effect on the Issue Date (other than the payment of management fees as described under clause (12) of this Section 4.11(b)), or any amendment thereto (so long as the amended agreement is not more disadvantageous to the Holders of the Notes in any material respect than such agreement immediately prior to such amendment) or any transaction contemplated thereby;

(10) the Transactions and the payment of all transaction, underwriting, commitment and other fees and expenses incurred in connection with the Transactions;

(11) investments by the Equity Sponsor in securities of the Company or any of its Restricted Subsidiaries so long as the investment is being offered generally to other investors on the same or more favorable terms and any other transactions involving the Company or any Restricted Subsidiary, on the one hand, and the Equity Sponsor or any of its Affiliates, on the other hand, which transactions, in the reasonable determination of the Board of Directors, are on commercially reasonable terms; and

(12) the payment of management fees to the Equity Sponsors pursuant to the Management Agreement as in effect on the Issue Date as described in the “Certain Relationships and Related Party Transactions — Management Agreements” section of the Company’s Offering Memorandum, dated July 24, 2012, relating to the offering of the Initial Notes.

Section 4.12 Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens.

Section 4.13 Suspension of Covenants.

(a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default or Event of Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the Company and the Restricted Subsidiaries shall not be subject to Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11 and clause (iv) of Section 5.01(a) (collectively, the “Suspended Covenants”).

(b) Upon the occurrence of a Covenant Suspension Event (the date of such occurrence, the “Suspension Date”), the amount of Excess Proceeds from Net Proceeds shall be set at zero.

(c) In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time pursuant to Section 4.13(a), and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Notes below an Investment Grade Rating or a Default or an Event of Default occurs and is continuing, then the Company and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events under this Indenture. The period of time between the Suspension Date and the Reversion Date is referred to as the “Suspension Period.”

(d) Notwithstanding that the Suspended Covenants may be reinstated, no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Registration Rights Agreement, the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants, and none of the Company or any of its Subsidiaries shall bear any liability for any actions taken or events occurring during the Suspension Period, or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, as a result of a failure to comply with the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred during the Suspension Period).

(e) On the Reversion Date, all Indebtedness incurred during the Suspension Period shall be classified to have been incurred or issued pursuant to Section 4.09(b)(2). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.07 shall

be made as though Section 4.07 had been in effect prior to, but not during, the Suspension Period. No Subsidiaries shall be designated as Unrestricted Subsidiaries during any Suspension Period. During the Suspension Period, any reference in the definitions of “Permitted Liens” or “First Priority Lien Obligations” to Section 4.09 or any provision thereof shall be construed as if such covenant were in effect during the Suspension Period.

(f) The Company shall provide written notice to the Trustee of the occurrence of any Covenant Suspension Event or Reversion Date. The Trustee shall have no obligation to (1) independently determine or verify if such events have occurred or (2) notify the Holders of the Notes of the occurrence of a Covenant Suspension Event or a Reversion Date.

Section 4.14 [Reserved.]

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000 (in aggregate principal amount)) of each Holder’s Notes in cash at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Special Interest, if any, on the Notes to be repurchased, to the date of repurchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). No later than 30 days following any Change of Control, the Company will send or cause to be sent a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

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

(2) the purchase price and the purchase date, which shall be no earlier than 10 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”);

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

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest and Special Interest, if any, after the Change of Control Payment Date;

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

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

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

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

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

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

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

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

The Paying Agent will promptly send or cause to be sent (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000.

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

(d) Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, (i) if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer or (ii) at the Company’s option, after the public announcement of the Change of Control.

Section 4.16 Guarantees.

If (a) the Company or any of its Restricted Subsidiaries acquires or creates a Domestic Subsidiary that is a Wholly Owned Restricted Subsidiary (or a Domestic Subsidiary that is a non-Wholly Owned Restricted Subsidiary if it Guarantees capital markets Indebtedness of the Company or a Subsidiary Guarantor), other than an Immaterial Subsidiary, on or after the Issue Date or (b) any such Immaterial Subsidiary ceases to meet the definition of Immaterial Subsidiary, then that newly acquired or created

Domestic Subsidiary or non-Immaterial Subsidiary, as applicable, must become a Guarantor and execute a supplemental indenture, grant a Second Priority Lien to the Trustee on behalf of the holders of the Notes on all of its property and assets constituting Collateral, become a party to the Security Documents and deliver an Opinion of Counsel to the Trustee.

A Subsidiary Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person), another Person unless:

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

(2) either:

(a) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (if other than the Subsidiary Guarantor) is organized or existing under the laws of the United States, any state thereof or the District of Columbia and assumes all the obligations of that Subsidiary Guarantor under this Indenture, the Subsidiary Guarantees, the Registration Rights Agreement and the Security Documents pursuant to a supplemental indenture reasonably satisfactory to the Trustee; or

(b) such sale or other disposition or consolidation or merger complies with Section 4.10 hereof.

Neither the merger or consolidation of a Subsidiary Guarantor with and into the Company (with the Company being the surviving entity) or another Subsidiary Guarantor nor the sale of all or substantially all of a Subsidiary Guarantor’s assets to the Company or another Subsidiary Guarantor need comply with the prior paragraph.

The Subsidiary Guarantee of a Subsidiary Guarantor will automatically and unconditionally be released upon written notice to the Trustee; provided, however, that failure to deliver such notice shall not affect the validity of such notice:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Sections 3.09 or 4.10 of this Indenture;

(2) in connection with any sale or other disposition of all or a majority of the Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Sections 3.09 or 4.10 of this Indenture;

(3) if the Company designates any Restricted Subsidiary that is a Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(4) upon legal defeasance or satisfaction and discharge of the Notes as provided in Section 8.02 and Article 11 of this Indenture; or

(5) all the obligations of such Subsidiary Guarantor under all Credit Facilities terminate and such Subsidiary Guarantor does not guarantee any other capital markets Indebtedness of the Company or another Subsidiary Guarantor.

Section 4.17 Payments for Consent.

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

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

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

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

The Company is required to deliver to the Trustee annually a written statement regarding compliance with this Indenture, and upon becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustee a statement specifying such Default or Event of Default.

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all such Notes to be due and payable immediately; provided, however, that the Company shall have 30 days to cure an Event of Default described in clause (10) of Section 6.01 hereof after it receives a written notice as set forth in clause (10) of Section 6.01 hereof.

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

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration or waive any existing Default or Event of Default and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Special Interest, if any, that has become due solely because of the acceleration) have been cured or waived.

Section 6.03 Other Remedies.

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

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

Section 6.04 Waiver of Past Defaults.

Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Special Interest, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every

purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

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

Section 6.06 Limitation on Suits.

Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

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

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

(3) such Holder or Holders offer the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

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

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

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use is unduly prejudicial to such Holders).

Section 6.07 Rights of Holders of Notes to Receive Payment.

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

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Special Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further

amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee and the Collateral Agent and their respective agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

Subject to the terms of the Security Documents, if the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First:to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection, including by the Collateral Agent;

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

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

Section 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any

party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

Section 7.01 Duties of Trustee.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

The Company will promptly notify the Trustee in writing when the Notes are listed on any stock exchange and upon any delisting thereof.

Section 7.07 Compensation and Indemnity.

(a) The Company will pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties will agree in writing from time to time.

The Trustee will notify the Company in writing 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 Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need (x) pay for any settlement made without its written consent, which consent will not be unreasonably withheld or delayed, or (y) reimburse any expense or indemnify against any of the foregoing loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or gross negligence.

(c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture and the removal or resignation of the Trustee.

Such Lien will survive the satisfaction and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(7) or (8) hereof occurs, the expenses and the compensation for the services (including the reasonable fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(f) The Trustee will comply with the provisions of TIA Section 313(b)(2) to the extent applicable.

Section 7.08 Replacement of Trustee.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may, upon 30 days’ written notice to the Company, resign in writing at any time and be discharged from the trust hereby created by so notifying the Company.

(1) the Trustee fails to comply with Section 7.10 hereof;

(2) the Trustee is adjudged 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 as Trustee hereunder or with respect to the Notes.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee; provided, however, that such Person shall be otherwise qualified and eligible under Article 7 hereof.

Section 7.10 Eligibility; Disqualification.

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or

state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition.

This Indenture will always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b).

Section 7.11 Preferential Collection of Claims Against Company.

The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. The Trustee hereby waives any right to set off any claim that it may have against the Company in any capacity (other than as Trustee) against any of the assets of the Company held by the Trustee in its capacity as Trustee.

ARTICLE 8
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Subsidiary Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Subsidiary Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all of their other obligations under such Notes, the Subsidiary Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium and Special Interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Company’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and

(4) the Legal Defeasance provisions of this Article 8.

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

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and any Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.15, 4.16, 4.17 and 4.18 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Subsidiary Guarantees, the Company and any Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Subsidiary Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(8) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Sections 8.02 or 8.03 hereof:

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

(2) in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

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

(B) since the date of this Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the

same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

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

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

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

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

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and Special Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the written request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written

certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

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

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Sections 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Sections 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Sections 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium or Special Interest, if any, or interest on any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes, the Subsidiary Guarantees or the Security Documents without the consent of any Holder of a Note:

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

(2) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes and Subsidiary Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets, as applicable;

(3) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not affect the legal rights hereunder of any Holder of the Note in a materially adverse manner;

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

(5) to conform the text of this Indenture, the Notes, the Security Documents or the Subsidiary Guarantees to any provision of the “Description of the Notes” section of the Company’s Offering Memorandum, dated July 24, 2012, relating to the offering of the Initial Notes, to the extent that such provision in that “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Indenture, the Subsidiary Guarantees, the Security Documents or the Notes and as set forth in an Officer’s Certificate;

(6) to mortgage, pledge, hypothecate or grant any other Lien in favor of the Collateral Agent for the benefit of itself, the Trustee, the Holders (and the holders or lenders of First Priority Lien Obligations or other Second Priority Lien Obligations), as security for the payment and performance of all or any portion of the First Priority Lien Obligations or the Obligations under the Notes, the Subsidiary Guarantees and any other Second Priority Lien Obligations, in any property or assets;

(7) to provide for the release of Collateral from the Second Priority Lien and the Security Documents when permitted or required by any of the Security Documents or this Indenture;

(8) to allow any Guarantor to execute a supplemental indenture and a Guarantee with respect to the Notes; or

(9) to evidence and provide for the acceptance and appointment under this Indenture by a successor Trustee.

In addition, without the consent of any Holder of the Notes, the Trustee and the Collateral Agent will be authorized to amend any Security Document (i) to add additional secured parties holding, and to secure any, other Second Priority Lien Obligations or First Priority Lien Obligations permitted by this Indenture with the same Lien priorities and rights as provided in the Intercreditor Agreement, (ii) to enter into intercreditor arrangements with the holders of any such Indebtedness described in clause (i) so long as the terms of such intercreditor arrangements are not less favorable to the Holders of Notes than the intercreditor provisions contained in the Security Agreement and the Intercreditor Agreement and (iii) to add parties (including collateral agents, administrative and other agents, trustees and lenders) to the Security Documents in respect of the incurrence of Indebtedness secured by Permitted Liens described in clause (16) of the definition thereof.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof), the Subsidiary Guarantees, the Notes and the Security Documents with the consent of the Holders of at least a

majority in principal amount of the Notes (including, without limitation, Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or Special Interest, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Security Documents, the Subsidiary Guarantees or such Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including any Additional Notes, if any) voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

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

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture, the Notes, or the Subsidiary Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof;

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

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

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

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium or Special Interest, if any, on the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.15 hereof);

(8) release any Guarantor that is a Significant Subsidiary from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture;

(9) make any change in the provisions of this Indenture or any Security Document dealing with the application of proceeds of the Collateral that would adversely affect the Holders of Notes; or

(10) make any change in the foregoing amendment and waiver provisions.

In addition, without the consent of at least 66-2/3% in aggregate principal amount of Notes then outstanding, an amendment, supplement or waiver may not have the effect of releasing all or substantially all of the Collateral from the Second Priority Liens (except as otherwise in accordance with the provisions of this Indenture and the Security Documents).

Section 9.03 Compliance with TIA.

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

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

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

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

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities

of the Trustee. In executing any amended or supplemental indenture, the Trustee shall receive and (subject to Section 7.01 hereof) will be fully protected in conclusively relying upon, in addition to the documents required by Section 13.04 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 and that such supplemental indenture is the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms. Notwithstanding the foregoing, no Opinion of Counsel will be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture provided that such amendment or supplement adding a new Guarantor is in the form of Exhibit E attached hereto.

ARTICLE 10
SUBSIDIARY GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium and Special Interest, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

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

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

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Subject to Section 6.06 hereof, each Guarantor hereby waives diligence, presentment, demand of 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, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Subsidiary Guarantee.

To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit D hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

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

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

In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Domestic Subsidiary after the date of this Indenture, the Company will cause such Domestic Subsidiary to comply with the provisions of this Article 10, to the extent applicable.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

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

(2) either:

(a) subject to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under this Indenture and the Subsidiary Guarantee on the terms set forth herein or therein; or

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

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture in the form of Exhibit E, executed and delivered to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05 Releases.

(a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee; provided that such sale or disposition does not violate the applicable provisions of this Indenture, including without limitation Section

4.10 hereof. Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof. Upon the Company’s written request, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee.

(b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee.

(c) Upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof, each Guarantor will be automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee.

Any Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11
SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

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

(1) either:

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

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

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

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

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

In addition, upon the Company’s request and upon delivery by the Company of an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied, the Trustee shall execute any discharge documentation.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

ARTICLE 12
SECURITY DOCUMENTS AND SECURITY

Section 12.01 Rights of the Collateral Agent.

(a) The Trustee is acting as Collateral Agent under the Security Documents and shall initially act as Collateral Agent for the benefit of the holders of all Second Priority Lien Obligations, including the Notes and, as Collateral Agent, shall be entitled to the protections, immunities and indemnities afforded the Trustee under Article 7.

(b) The Collateral Agent is authorized and empowered to appoint one or more co-Collateral Agents or sub-agents as it deems necessary or appropriate and shall have no liability for the performance of such co-Collateral Agent or sub-agent so long as it was selected with due care.

(c) Neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents shall be responsible for the existence, genuineness, value or protection of any Collateral (except for the safe custody of any Collateral in their possession and the accounting

for moneys actually received by them hereunder), for the legality, enforceability, effectiveness or sufficiency of the Security Documents, for the creation, perfection, priority, sufficiency or protection of any Second Priority Lien, or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Second Priority Liens or Security Documents or for any delay in doing so. The Trustee and the Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in their possession if such Collateral is accorded treatment substantially equal to that which they accord their own property.

(d) Subject to the terms of the Security Agreement, the Collateral Agent shall be subject to such directions as may be given it by the Trustee from time to time as required or permitted by this Indenture and the Intercreditor Agreement. Except as directed by the Trustee and as required or permitted by this Indenture, the Intercreditor Agreement or the other Security Documents, the Collateral Agent shall not be obligated:

(1) to act upon directions purported to be delivered to it by any other Person;

(2) to foreclose upon or otherwise enforce any Second Priority Lien; or

(3) to take any other action whatsoever with regard to any or all of the Second Priority Liens, Security Documents or Collateral.

(e) The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the enforcement of the Second Priority Liens or Security Documents.

(f) In acting as Collateral Agent or co-Collateral Agent, the Collateral Agent and each co-Collateral Agent may rely upon and enforce each and all of the rights, powers, immunities, indemnities and benefits of the Trustee under Article 7.

(g) Each successor Trustee shall become the successor Collateral Agent as and when the successor Trustee becomes the Trustee.

Section 12.02 Security Documents.

(a) In order to secure the due and punctual payment of the Notes, the Company has entered or will enter into the Security Documents to create the Second Priority Liens on the Collateral in accordance with the terms thereof. In the event of a conflict between the terms of this Indenture and the Intercreditor Agreement, the Intercreditor Agreement shall control.

(b) Each Holder of a Note, by accepting such Note, (i) agrees to all of the terms and provisions of the Intercreditor Agreement and the other Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and the automatic amendment or waiver of the Security Documents pursuant to the terms of the Intercreditor Agreement) and (ii) appoints the Collateral Agent as its collateral agent and authorizes the Trustee and the Collateral Agent to enter into the Intercreditor Agreement and the other Security Documents, to bind the Holders on the terms set forth in the Security Documents, to perform and observe its obligations under the Security Documents and, unless violative of the provisions hereof and thereof, to execute any and all documents, amendments, waivers, consents, releases or other instruments required (or authorized) to be executed by it pursuant to the terms thereof.

(c) Each Holder of a Note, by accepting such Note, acknowledges and agrees that, so long as the First Priority Lien Obligations are outstanding, the holders of the First Priority Liens may

change, waive, modify or vary the Security Documents; provided that any such change, waiver, modification or variance materially adversely affecting the rights of the Holders of the Notes (and not the holders of the First Priority Liens or any other secured creditors in a like or similar manner) will require the consent of the Trustee (acting at the direction of Holders of a majority of the aggregate principal amount of the Notes outstanding); provided further, however, that notwithstanding the foregoing, the holders of the First Priority Liens may (i) direct the First Priority Lien Representative to take actions with respect to the Collateral (including the release of the Collateral and the manner of realization) without the consent of the Holders of the Notes and (ii) agree to modify the Security Documents, without the consent of the Holders of the Notes, to secure additional extensions of credit and add additional secured creditors so long as such modifications do not expressly violate the provisions of the Credit Agreement or this Indenture.

Section 12.03 Application of Proceeds of Collateral.

Upon any realization upon the Collateral, the proceeds thereof shall be applied, subject to the terms of the Intercreditor Agreement, in accordance with the Security Documents and Section 6.10 hereof.

Section 12.04 Possession, Use and Release of Collateral.

(a) Subject to the terms of the Intercreditor Agreement and the other Security Documents, the Company shall have the right to remain in possession and retain exclusive control of the Collateral (other than any cash, securities, obligations and cash equivalents constituting part of the Collateral to the extent deposited with the Collateral Agent, or any agent of the Collateral Agent, in accordance with the provisions of the Security Documents and other than as set forth in the Security Documents), to freely operate the Collateral and to collect, invest and dispose of any income therefrom.

(b) In the event of the release of Second Priority Liens on any property constituting Collateral pursuant to Section 12.04(e)(3), the Collateral Agent will, at the Company’s expense, promptly execute and deliver to the Company such documents as the Company shall reasonably request to evidence the release of such item of Collateral from the Second Priority Liens; provided that the Company shall have delivered to the Collateral Agent, at least five Business Days prior to the date of the proposed release, a written request for release describing the item of Collateral and the terms of the sale, lease, transfer or other disposition in reasonable detail, including, without limitation, the price thereof and any expenses in connection therewith, together with a form of release for execution by the Collateral Agent and an Officer’s Certificate of the Company to the effect that the relevant transaction is in compliance with this Indenture, the Intercreditor Agreement and the other Security Documents, and as to such other matters as the Trustee may reasonably request. Notwithstanding the preceding sentence, all purchasers and grantees of any property or rights purporting to be released from the Second Priority Liens shall be entitled to rely upon any release executed by the Trustee hereunder as sufficient for the purpose of this Indenture and as constituting a good and valid release of the property therein described from the Second Priority Liens.

(c) Each Holder of a Note, by accepting such Note, acknowledges and agrees that, so long as any First Priority Lien Obligations are outstanding, the holders of the First Priority Lien Obligations will control at all times all remedies and other actions related to the Collateral and the Second Priority Liens will not entitle the Collateral Agent, the Trustee or the Holders of any Notes to take any action whatsoever with respect to the Collateral. As a result, so long as any First Priority Lien Obligations are outstanding, neither the Collateral Agent nor the Trustee nor the Holders of the Notes will be able to force a sale of the Collateral or otherwise exercise remedies normally available to secured creditors without the concurrence of the holders of the First Priority Lien Obligations.

(d) Each Holder of a Note, by accepting such Note, acknowledges and agrees that, at such time as (i) the First Priority Lien Obligations have been satisfied in full in cash in accordance with the terms thereof and all commitments and letters of credit thereunder have been terminated or (ii) the holders of the First Priority Lien Obligations have released their First Priority Liens on all or any portion of the Collateral, the Second Priority Liens will also be automatically released to the same extent; provided, however, that (x) in the case of clause (i) of this sentence, in the event that an Event of Default shall have occurred and be continuing as of the date on which the First Priority Lien Obligations are repaid in full and terminated as described in clause (i), the Second Priority Liens on the Collateral will not be released, except to the extent the Collateral or any portion thereof was disposed of in order to repay the First Priority Lien Obligations secured by the Collateral and, thereafter, subject to the provisions of the Security Agreement, the Trustee (acting at the direction of the Holders of a majority in outstanding principal amount of Notes) will have the right to direct the Collateral Agent to foreclose upon the Collateral (but, in such event, the Second Priority Liens will be released when such Event of Default and all other Events of Default under this Indenture shall cease to exist), and (y) in the case of clause (ii) of this sentence, if the First Priority Lien Obligations (or any portion thereof) are thereafter secured by assets that would constitute Collateral, the Notes will then be secured by the Second Priority Liens on such Collateral, to the same extent provided pursuant to the Security Documents. If the Company subsequently Incurs obligations under the Credit Agreement or other First Priority Lien Obligations which are secured by assets of the Company or any Guarantors of the type constituting Collateral, then the Second Priority Lien Obligations will be secured at such time by a Second Priority Lien on the collateral securing such First Priority Lien Obligations to the same extent provided by the Security Documents.

(e) Each Holder of a Note, by accepting such Note, acknowledges and agrees that the Second Priority Liens will be released automatically and without the need for any further action by any Person (so long as such release is in compliance with the TIA):

(1) as to all of the Collateral, upon payment in full of the principal of, and accrued and unpaid interest (including Special Interest) and premium, if any, on the Notes;

(2) as to all of the Collateral, upon defeasance or discharge of the Notes in accordance with the provisions described under Article 8 or Section 11.01 hereof;

(3) as to any property or assets constituting Collateral that is sold, transferred or otherwise disposed of by the Company or any of its subsidiaries (other than to the Company or any Guarantor) in a transaction not prohibited by this Indenture, at the time of such sale, transfer or disposition; or

(4) as to any property constituting Collateral that is owned by a Guarantor that has been released from its obligations under its Subsidiary Guarantee in accordance with Sections 4.16 and 10.05 hereof, concurrently with the release of such Guarantee.

(f) Each Holder of a Note, by accepting such Note, acknowledges that, notwithstanding the provisions set forth in this Section 12.04, the Company and any Guarantor may, without any release or consent by the Trustee or the Collateral Agent, perform a number of activities in the ordinary course in respect of the Collateral to the extent not restricted or prohibited by the Security Documents and this Indenture, including, without limitation, (i) selling or otherwise disposing of, in any transaction or series of related transactions, any property subject to the Second Priority Liens which has become worn out, defective or obsolete or not used or useful in the business; (ii) abandoning, terminating, canceling, releasing or making alterations in or substitutions of any leases or contracts subject to the Second Priority Liens; (iii) surrendering or modifying any franchise, license or permit subject to the Second Priority Liens

which it may own or under which it may be operating; (iv) altering, repairing, replacing, changing the location or position of and adding to its structures, machinery, systems, equipment, fixtures and appurtenances; (v) granting a license of any intellectual property; (vi) selling, transferring or otherwise disposing of inventory in the ordinary course of business; (vii) selling, collecting, liquidating, factoring or otherwise disposing of accounts receivable in the ordinary course of business; (viii) making cash payments (including for the repayment of Indebtedness) from cash that is at any time part of the Collateral in the ordinary course of business that are not otherwise prohibited by this Indenture; and (ix) abandoning any property which is no longer used or useful in the Company’s business. The release of any Collateral from the Liens pursuant to the terms of this Indenture and the Security Documents shall not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent that the Collateral is released pursuant to the terms of this Section 12.04.

Section 12.05 Opinion of Counsel.

So long as the Security Documents have not been terminated in accordance with the terms thereof, the Company shall deliver to the Collateral Agent, if and for so long as such delivery is required by Section 314(b) of the TIA, at least annually, within 90 days after September 30 of each year (commencing with September 30, 2012), an Opinion of Counsel either stating that, in the opinion of such counsel, such action has been taken with respect to the recording, filing, re-recording and refiling of this Indenture as is necessary to maintain the Second Priority Liens, and reciting the details of such action, or referring to prior Opinions of Counsel when such details were given, or stating that in the opinion of such counsel, no such action is necessary to maintain such Second Priority Liens.

Section 12.06 Further Assurances.

The Company and each Guarantor shall (a) furnish to the Collateral Agent (for the benefit of the Trustee and the Holders) from time to time, at the Company’s or such Guarantor’s sole cost and expense, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as is necessary or appropriate, all in such detail as is necessary or appropriate; (b) subject to the Intercreditor Agreement, at any time and from time to time, and at the sole expense of the Company or such Guarantor, promptly execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register, as applicable, any and all such further acts, deeds, conveyances, security agreements, mortgages, assignments, estoppel certificates, financing statements and continuations thereof (including, without limitation, any financing or continuation statements under the Uniform Commercial Code (or other similar laws) in effect in any jurisdiction with respect to the Second Priority Liens), termination statements, notices of assignment, transfers, certificates, assurances and other instruments as may be required from time to time in order to (i) subject to the Second Priority Liens any of the property or assets constituting Collateral and (ii) perfect and maintain the validity, effectiveness, perfection and priority of any of the Second Priority Liens to the extent required hereunder or by the Security Documents; (c) subject to the Intercreditor Agreement and without limitation of the foregoing subsection (b), with respect to any fee interest in real property constituting Collateral acquired after the Issue Date by the Company or any Guarantor, promptly (i) execute and deliver a mortgage in favor of the Collateral Agent, creating a security interest for the benefit of the Trustee and the Holders of the Notes, covering such real property, and (ii) deliver to the Collateral Agent title and extended coverage insurance covering such real property in an amount at least equal to the purchase price of such real property, with local fixture filings being made in respect of fixtures associated with such real property as well as a current “ALTA” survey thereof, together with a surveyor’s certificate; and (d) promptly deliver to the Collateral Agent such Opinions of Counsel, if any, as is necessary or appropriate with respect to this Section 12.06 (including opinions as to validity, enforceability and perfection of security interests).

Section 12.07 Certain TIA Requirements.

(a) To the extent applicable, and in addition to any other requirements under this Indenture, the Company will cause § 313(b) of the TIA (relating to reports) and § 314(d) of the TIA (relating to the release of property or securities from the Second Priority Liens or relating to the substitution for such Liens of any property or securities to be subjected to the Secured Priority Liens) to be complied with and will furnish to the Trustee, prior to each proposed release of Collateral pursuant to this Indenture and the Security Documents, all documents required by § 314(d) of the TIA and an Opinion of Counsel to the effect that the accompanying documents constitute all documents required by § 314(d) of the TIA.

(b) Notwithstanding anything to the contrary in this Section 12.07, the Company will not be required to comply with all or any portion of § 314(d) of the TIA if the Board of Directors of the Company determines, in good faith based on advice of counsel, that, under the terms of § 314(d) of the TIA and/or any interpretation or guidance as to the meaning thereof of the SEC or its staff, including publicly available “no action” letters or exemptive orders, all or any portion of § 314(d) of the TIA is inapplicable to all or any part of the Collateral or the release, deposit or substitution thereof.

Section 12.08 Suits to Protect the Collateral.

Subject to the provisions of the Intercreditor Agreement and the Security Documents, the Collateral Agent shall have the authority to institute and to maintain such suits and proceedings, at the expense of the Company, as the Collateral Agent may deem reasonably expedient to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Collateral Agent may deem reasonably expedient to preserve or protect its interests and the interests of the Holders of the Notes in the Collateral (including suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Second Priority Liens or be prejudicial to the interests of the Holders of the Notes).

Section 12.09 Purchaser Protected.

In no event shall any purchaser in good faith or other transferee of any property purported to be released hereunder be bound to ascertain the authority of the Collateral Agent to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted to be sold by this Article Twelve, be under obligation to ascertain or inquire into the authority of the Company or any Guarantor, as applicable, to make any such sale or other transfer.

Section 12.10 Powers Exercisable by Receiver or Trustee.

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 12 upon the Company or any Guarantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 12.

Section 12.11 Release of Second Priority Liens.

In the event that the Company delivers an Officer’s Certificate certifying that (a) its obligations under this Indenture have been defeased or discharged by complying with the provisions of Article Eight or Section 11.01 or (b) a Guarantor shall have been released from its obligations under its Subsidiary Guarantee the Second Priority Liens on all property and assets (including any Capital Stock) constituting Collateral (in the case of clause (a)) or the property and assets (including any Capital Stock) constituting Collateral owned by such Guarantor (in the case of clause (b)) shall be released, and the Collateral Agent shall (i) at the Company’s expense, promptly execute and deliver such releases, termination statements and other instruments (in recordable form, where appropriate) as the Company or any Guarantor, as applicable, may reasonably request to evidence the termination of such Second Priority Liens and (ii) not be deemed to hold such Second Priority Liens for the benefit of the Trustee and the Holders of Notes.

(or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and Wells Fargo Bank, National Association, a national banking association, as trustee under the Indenture referred to below (the “Trustee”).

W I T N E S S E T H

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of August 7, 2012, providing for the issuance of 7.625% Second Lien Senior Secured Notes due 2020 (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 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

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

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