The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors 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.

Notes issued in definitive form will be substantially in the form of Exhibit A 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.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for the Issuer by manual, facsimile or other electronic 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 an authorized signatory 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 Issuer signed by an Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes up to the aggregate principal amount stated in such Authentication Order for such Additional Notes issued hereunder (it being understood that, notwithstanding anything to the contrary contained in this Indenture, no Opinion of Counsel pursuant to Section 12.02 will be required by the Trustee with the authentication of the Initial Notes on the Issue Date). The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to one or more Authentication Orders, except as provided in Section 2.08 hereof.

Additional Notes may be issued from time to time subject to the terms of this Indenture, including Section 4.09. The Initial Notes and the Additional Notes shall be treated as a single class for all purposes of this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase, and Additional Notes shall have identical terms and conditions as the Initial Notes, other than (i) the date of issuance and (ii) if applicable, the first Interest Payment Date and date from which interest will begin to accrue; provided however that if any Additional Notes are not fungible with the Initial Notes for U.S. federal income tax or other purposes, such Additional Notes will have a separate CUSIP number.

The Trustee may appoint an authenticating agent acceptable to the Issuer 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 Issuer.

Section 2.03 Registrar and Paying Agent.

32

The Issuer 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 Issuer 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 Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest, if any, on, the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time 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 Issuer or a Subsidiary) will have no further liability for the money. If the Issuer 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 Issuer, 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. If the Trustee is not the Registrar, the Issuer 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.

(g) 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.

(h) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Issuer 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 Issuer 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 Issuer, 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 Issuer 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 any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

44

(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 Issuer 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 (subject to the record date provisions of the Notes) interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer 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 any Opinion 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.

(9) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or Beneficial Owners 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.

Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary. The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, any Participant in the Depositary or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Participant thereof, with respect to any ownership interest in Global Notes or with respect to the delivery to any Participant, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or purchase) or the payment of any amount, under or with respect to such Global Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Global Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely conclusively and shall be fully protected in relying upon information furnished by the Depositary with respect to its Participants and any beneficial owners.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer 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 Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

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

Every replacement Note is an additional obligation of the Issuer 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 Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for purposes of Section 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 Issuer, 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 Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, 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 the Trustee knows are so owned will be so disregarded.

46

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuer 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 Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer 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 Issuer 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 (subject to the record retention requirements of the Exchange Act) in accordance with its customary procedures. Certification of the cancellation of all canceled Notes will be delivered to the Issuer upon request. The Issuer 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 Issuer defaults in a payment of interest on the Notes, to the extent permitted by any Applicable Laws, 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, provided that no special record date shall be required with respect to defaulted interest that is paid within the applicable grace period. The Issuer 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 Issuer 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 Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will mail or cause to be mailed (or, in the case of Global Notes, transmit with the procedures of the Depositary) to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least five Business Days (or such shorter period as shall be satisfactory to the Trustee) prior to the giving notice of a redemption, an Officer’s Certificate setting forth:

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

47

(2) the redemption date;

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

(4) the redemption price or the method by which it is to be determined.

Section 3.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a by lot basis (or, in the case of Notes issued in global form, based on a method that most nearly approximates a by lot selection) unless otherwise required by law or applicable stock exchange requirements; provided, however, that so long as DTC serves as a Depositary for Notes issued in global form, any redemption will comply with the applicable procedural requirements of DTC with respect to redemption.

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in minimum amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. 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.

Section 3.03 Notice of Redemption.

Subject to the provisions of Section 3.09 hereof, at least 10 days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed, by first class mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary), a notice of redemption to each Holder (with a copy to the Trustee) whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed or transmitted 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 Articles 8 or 11 hereof.

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

(1) the redemption date;

(2) the redemption price, or if not then ascertainable, the manner of calculation thereof;

(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 upon cancellation of the original Note;

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

48

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

(6) that, unless the Issuer defaults in making such redemption payment, interest 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;

(8) 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; and

(9) any conditions precedent to which the redemption is subject.

At the Issuer’s written request, the Trustee will give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 30 days (or such shorter period as shall be satisfactory to the Trustee) prior to the redemption date, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the form of the notice to be provided.

Any such redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of any related Equity Offering, Change of Control or other transaction. In addition, if such redemption is subject to the satisfaction of one or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date as so delayed. In addition, the Issuer may provide in such notice that payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person (it being understood that any such provision for payment by another Person will not relieve the Issuer and the Guarantors from their obligations with respect to such redemption).

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is delivered or mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject to the fourth paragraph of Section 3.03.

Section 3.05 Deposit of Redemption Price.

No later than 11:00 a.m. Eastern Time on the redemption date, the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of and accrued and unpaid interest, if any, on all Notes to be redeemed.

49

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. If a Note is redeemed 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 is not so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed in Part.

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

Section 3.07 Optional Redemption.

(a) Except as described below, the Notes will not be redeemable at the Issuer’s option.

(b) At any time prior to October 1, 2025, the Issuer may on any one or more occasions redeem up to 40% of the aggregate principal amount of Notes issued under this Indenture (including any Additional Notes), upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 111.75% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date with an amount not to exceed the amount of net cash proceeds of one or more Equity Offerings consummated after the Issue Date; provided that:

(1) at least 50% of the aggregate principal amount of Notes issued under this Indenture (including Additional Notes but excluding Notes held by the Issuer and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption (unless all such Notes are otherwise being repurchased or redeemed substantially concurrently pursuant to another provision described under this Section 3.07); and

(2) the redemption occurs within 180 days of the date of the closing of such Equity Offering.

(c) At any time prior to April 1, 2028 (the “Par Call Date”), the Issuer may on any one or more occasions redeem all or any part of the Notes upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Redemption Premium as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption.

Section 3.08 Mandatory Redemption; Offers to Purchase; Purchase of Notes.

The Issuer will not be required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Issuer may be required to offer to purchase the Notes as described under Section 4.10 and Section 4.15. The Parent, the Restricted Subsidiaries and their respective Affiliates may at any time and from time to time purchase the Notes in the open market, by tender offer, in negotiated transactions or otherwise.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuer 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 Pari Passu Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay 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 Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Pari Passu Indebtedness (on a pro rata basis based on the principal amount of Notes and such other Pari Passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Pari Passu 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.

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

51

Upon the commencement of an Asset Sale Offer, the Issuer will send, by first class mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary), a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

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

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

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

(4) that, unless the Issuer 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) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in minimum denominations of $2,000 or an integral multiple of $1,000 in excess thereof;

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

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

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

52

On or before the Purchase Date, the Issuer 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 Issuer in accordance with the terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than two Business 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 Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon written request from the Issuer, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Purchase Date.

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Parent were required to file such reports.

Notwithstanding any of the foregoing, at any time when the Parent does not otherwise file such reports with the Commission, (a) no certifications, reports or attestations concerning the financial statements, disclosure controls and procedures or internal controls that would otherwise be required pursuant to the Sarbanes-Oxley Act of 2002, as amended, and the SEC rules and regulations implementing that Act, will be required; (b) no financial schedules specified in Regulation S-X under the Securities Act will be required; (c) compliance with the requirements of Item 10(e) of Regulation S-K under the Securities Act will not be required; (d) information specified in Rules 13-01 and 13-02 of Regulation S-X under the Securities Act with respect to Subsidiaries and Affiliates will not be required; and (e) no exhibits pursuant to Item 601 of Regulation S-K under the Securities Act will be required.

(b) In addition, the Issuer, the Parent and the Subsidiary Guarantors agree that, for so long as any Notes remain outstanding, at any time they are not required to file the reports required by this Section 4.03 with the SEC, they will furnish to the Trustee, Holders and to securities analysts and bona fide prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Further, the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the SEC’s EDGAR filing system (or its successor) or made publicly available on a website.

(b) So long as any of the Notes are outstanding, the Issuer and the Parent will deliver to the Trustee, within five Business Days of any of their Officers becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer and the Parent are taking or propose to take with respect thereto, but only to the extent such Default or Event of Default has not been cured by the end of such five Business Day period. The Trustee will not be deemed to have knowledge of any Defaults or Events of Default unless written notice of an event, which is in fact a Default, has been delivered to the Trustee at its Corporate Trust Office and such notice references the Notes and this Indenture and states that it is a “Notice of Default.”

Section 4.05 Taxes.

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

Section 4.06 Stay, Extension and Usury Laws.

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

(a) Subject to the exceptions set out under paragraph (b) below, the Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise (collectively, “incur”), with respect to any Indebtedness (including Acquired Debt), and the Parent will not issue any Disqualified Stock and will not permit its Restricted Subsidiaries to issue any Disqualified Stock or Preferred Equity; provided, however, that the Parent and its Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any Restricted Subsidiary may issue Preferred Equity, if (A) on the date of incurrence or issuance thereof the Fixed Charge Coverage Ratio for the applicable Test Period would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), and (B) the Cash Asset Coverage Ratio would have been at least 3.0 to 1.0, in each case as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Equity had been issued, as the case may be, on the first day of the relevant Test Period.

(b) Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness, Disqualified Stock or Preferred Equity:

(1) Indebtedness of the Parent or any of its Restricted Subsidiaries under Credit Facilities in an aggregate principal amount at any time outstanding not to exceed $100.0 million;

(5) Indebtedness of the Parent owing to any of its Restricted Subsidiaries or Indebtedness of any of its Restricted Subsidiaries owing to the Parent or any Restricted Subsidiary of the Parent; provided that (A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Parent or a Restricted Subsidiary and (B) any transfer of such Indebtedness to a Person that is not the Parent or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Parent or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (5);

(6) the issuance by any of the Parent’s Restricted Subsidiaries to the Parent or to any of its Restricted Subsidiaries of shares of Preferred Equity; provided, however, that: (A) any subsequent issuance or transfer of Equity Interests that results in any such Preferred Equity being held by a Person other than the Parent or a Restricted Subsidiary of the Parent; and (B) any sale or other transfer of any such Preferred Equity to a Person that is not either the Parent or a Restricted Subsidiary of the Parent, will be deemed, in each case, to constitute an issuance of such Preferred Equity by such Restricted Subsidiary that was not permitted by this clause (6);

(7) Indebtedness or Disqualified Stock of the Parent or Indebtedness or Preferred Equity of a Restricted Subsidiary incurred and outstanding on the date on which such Restricted Subsidiary was directly or indirectly acquired by the Parent after the Issue Date or on the date it otherwise becomes a Restricted Subsidiary (in either case, whether or not such Indebtedness, Disqualified Stock or Preferred Equity was incurred in contemplation of such acquisition); provided that, that after giving effect to such acquisition and incurrence, either (A) the Parent 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 (B) the Fixed Charge Coverage Ratio for the applicable Test Period would be equal to or greater than immediately prior to such acquisition and incurrence;

(8) Indebtedness of the Parent and its Restricted Subsidiaries incurred in respect of worker’s compensation claims or claims arising under similar legislation, self-insurance or similar obligations, performance, surety and similar bonds and completion guarantees provided by the Parent and its Restricted Subsidiaries in the ordinary course of business;

(15) (i) the factoring of accounts receivable and (ii) reverse factoring or confirming of accounts payable, in each case arising in the ordinary course of business;

(19) Indebtedness consisting of the financing of insurance premiums or take-or-pay obligations contained in supply agreements, in each case, in the ordinary course of business;

(20) [reserved];

(21) [reserved];

(22) the incurrence of Indebtedness by the Parent or any Restricted Subsidiary to the extent that the net proceeds thereof are promptly deposited with the Trustee to satisfy and discharge the Notes in accordance with this Indenture;

(23) Convertible Indebtedness of the Parent that is not guaranteed by any Subsidiary of the Parent; and

(24) any Refinancing Indebtedness incurred with respect to the refinancing of any Indebtedness permitted under Section 4.09(a) or clauses (2), (3), (4), or (7) of this Section 4.09(b).

The Issuer and the Guarantors will not incur any Indebtedness (other than intercompany Indebtedness incurred pursuant to clause (5) of this Section 4.09(b)) that is contractually subordinated in right of payment to any other Indebtedness of the Issuer or the applicable Guarantor, unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuer or the Guarantors solely by virtue of being unsecured or by virtue of being secured on a junior priority basis.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories described in paragraphs (b)(1) through (24) of this Section 4.09, or is entitled to be incurred pursuant to paragraph (a) of this Section 4.09, the Issuer will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09.

The accrual of interest or Preferred Equity dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Equity as Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Equity or Disqualified Stock in the form of additional shares of the same class of Preferred Equity or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Equity or Disqualified Stock for purposes of this Section 4.09. For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Parent 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.

65

For purposes of determining compliance with this Section 4.09, 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, 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.

With respect to any acquisition of a Permitted Business or long-term assets used or useful in a Permitted Business (whether by merger, consolidation or other business combination or the acquisition of Capital Stock), for purposes of determining whether:

(1) any Indebtedness (including Acquired Debt) that is being incurred in connection with such acquisition is permitted to be incurred in compliance with this Section 4.09; and

(2) whether any Lien being incurred to secure any such Indebtedness is permitted to be incurred in accordance with Section 4.12,

any calculation of the Fixed Charge Coverage Ratio, Consolidated Total Assets or CFADS may be made, at the option of the Parent, using the date that the definitive agreement for such acquisition is entered into (the “Acquisition Agreement Date”) as the applicable date of determination of the Fixed Charge Coverage Ratio, Consolidated Total Assets or CFADS, as the case may be, in each case with such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed Charge Coverage Ratio.” For the avoidance of doubt, if the Parent elects to use the Acquisition Agreement Date as the applicable date of determination in accordance with the foregoing, any fluctuation or change in the Fixed Charge Coverage Ratio, CFADS or Consolidated Total Assets of the Parent or the Permitted Business or assets to be acquired subsequent to the Acquisition Agreement Date and prior to the consummation of such acquisition will not be taken into account for purposes of determining whether any Indebtedness (including Acquired Debt) that is being incurred in connection with such acquisition is permitted to be incurred in compliance with this Section 4.09, or whether any Lien being incurred to secure any such Indebtedness is permitted to be incurred in accordance with Section 4.12, but any Indebtedness, Investment or other transaction that is required to be given pro forma effect in accordance with the applicable adjustment provisions described above incurred or consummated after the Acquisition Agreement Date and on or prior to the consummation of such acquisition will be taken into account.

66

If any Indebtedness is incurred, or Disqualified Stock or Preferred Stock is issued, in reliance on a basket measured by reference to a percentage of Consolidated Total Assets or an amount of CFADS, and any refinancing thereof would cause the percentage of Consolidated Total Assets or amount of CFADS, as applicable, to be exceeded if calculated based on the Consolidated Total Assets or CFADS, as applicable, on the date of such refinancing, such percentage of Consolidated Total Assets or amount of CFADS, as applicable, will not be deemed to be exceeded to the extent the principal amount of such newly incurred Indebtedness, the liquidation preference of such newly issued Disqualified Stock or the amount of such newly issued Preferred Stock does not exceed the sum of (i) the principal amount of such Indebtedness, the liquidation preference of such Disqualified Stock or the amount of such Preferred Stock being refinanced, extended, replaced, refunded, renewed or defeased plus (ii) any accrued and unpaid interest on the Indebtedness, any accrued and unpaid dividends on the Preferred Stock and any accrued and unpaid dividends on the Disqualified Stock being so refinanced, extended, replaced, refunded, renewed or defeased plus (iii) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness, Preferred Stock or Disqualified Stock and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the issuance of such new Indebtedness, Preferred Stock or Disqualified Stock or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness, Preferred Stock or Disqualified Stock.

Section 4.10 Limitation on Sales of Assets.

(a) The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate an Asset Sale unless:

(1) the Parent (or the relevant Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement in connection with such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of;

(2) at least 75% of the consideration received in the Asset Sale and all other Asset Sales since the Issue Date (on a cumulative basis) by the Parent or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (2), each of the following will be deemed to be cash:

(A) any liabilities, as recorded on the balance sheet of the Parent or any Restricted Subsidiary (other than contingent liabilities), that are assumed or discharged by the transferee of any such assets and as a result of which the Parent and its Restricted Subsidiaries are no longer obliged with respect to such liabilities or are indemnified against further liabilities;

67

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

(C) any Capital Stock or assets of the kind referred to in clauses (b)(1)(B) or (D) below;

(D) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that the Parent and each other Restricted Subsidiary are released from any guarantee of such Indebtedness in connection with such Asset Sale;

(E) consideration consisting of Indebtedness of the Parent or any Guarantor received from persons who are not the Parent or any Restricted Subsidiary;

(F) any consideration consisting of Equity Interests in an entity (including a Non-Recourse Subsidiary) engaged in a Permitted Business received in connection with the sale or exchange of an Equity Interest in a Restricted Subsidiary so long as after giving effect to such transaction, the entity in which the Equity Interest has been sold or exchanged remains a Restricted Subsidiary; and

(G) any Designated Non-cash Consideration received by the Parent or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received since the Issue Date pursuant to this clause (G) that is at that time outstanding, not to exceed the greater of (i) $75.0 million or (ii) 2.0% of Consolidated Total Assets, determined at the time of receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being determined as of the date of receipt thereof and without giving effect to subsequent changes in value).

(b) within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Parent (or the applicable Restricted Subsidiary, as the case may be) may:

(1) apply an amount of cash equal to the amount of such Net Proceeds (at the option of the Parent or Restricted Subsidiary):

(A) to redeem Notes as described under Section 3.07, to purchase Notes through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or to purchase Notes pursuant to an offer to all Holders at a purchase price equal to at least 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the date of purchase (a “Notes Offer”), which Notes Offer will constitute an application of Net Proceeds pursuant to this clause to the extent of the amount of the Notes Offer, whether or not any Notes are tendered;

68

(B) 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 (including a Non-Recourse Subsidiary);

(C) to make a capital expenditure;

(D) to acquire other assets (other than Capital Stock) not classified as current assets under GAAP that are used or useful in a Permitted Business;

(E) to repurchase, prepay, redeem or repay (i) secured Indebtedness of the Parent or any of its Restricted Subsidiaries under Credit Facilities and (ii) Pari Passu Indebtedness; provided that in the case of clause (ii), a pro rata portion of such amount of cash is applied to redeem Notes as described under Section 3.07, to purchase the Notes through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or to make a Notes Offer, which Notes Offer will constitute an application of such amount of cash pursuant to this clause to the extent of the amount of the Notes Offer, whether or not any Notes are tendered;

(F) to repurchase, prepay, redeem or repay any Non-Recourse Financing; or

(G) any combination of the foregoing; or

(2) enter into a binding commitment to apply the Net Proceeds pursuant to clauses (b)(1)(B), (C) or (D) of this Section 4.10; provided that such binding commitment will be treated as a permitted application of the Net Proceeds from the date of such commitment until the earlier of: (x) the date on which such acquisition or expenditure is consummated; and (y) the 180th day following the expiration of the aforementioned 365-day period.

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

(c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within ten Business Days thereof, the Issuer will make an Asset Sale Offer to all Holders (with a copy to the Trustee) and may make an offer to all holders of other Pari Passu Indebtedness to purchase, prepay or redeem with the Excess Proceeds the maximum principal amount of Notes and such other Pari Passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price for the Notes in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of

69

an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Pari Passu Indebtedness tendered into (or to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds or if the aggregate amount of the Notes tendered pursuant to a Notes Offer exceeds the amount of the Excess Proceeds so applied, such Notes and such other Pari Passu Indebtedness, if applicable, will be purchased on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. An Asset Sale Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of the Indenture, Notes and/or guarantees (but the Asset Sale Offer may not condition tenders on the delivery of such consents). The Issuer may satisfy the foregoing obligation with respect to any Net Proceeds from an Asset Sale by making an offer to purchase Notes with respect to the amount of all or part of the available Net Proceeds prior to the expiration of the application period referred to above with respect to the amount of all or a part of the available Net Proceeds in advance of being required to do so by this Section 4.10(c) and all references in this Section 4.10(c) or Section 3.09 to the Asset Sale Offer and procedures with respect thereto shall apply equally to such advance portion of such advance offer.

(d) The Issuer 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 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 hereof or this Section 4.10, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance.

Section 4.11 Limitation on Transactions with Affiliates.

(a) The Parent will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into or suffer to exist any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange or lease of assets or property or the rendering of any service) with, or for the benefit of, any Affiliate of the Parent or any Restricted Subsidiary involving aggregate payments or consideration in excess of $5.0 million, unless:

(1) such transaction or series of transactions is on terms that, taken as a whole, are not materially less favorable to the Parent or such Restricted Subsidiary, as the case may be, than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis with third parties that are not Affiliates; and

(2) with respect to any transaction or series of related transactions involving aggregate payments or the transfer of assets or the provision of services, in each case having a value greater than $75.0 million, the Board of Directors of the Parent must approve such transaction.

70

(b) Notwithstanding the foregoing, the restrictions set forth in this Section 4.11 will not apply to:

(1) customary directors’ fees and expenses, indemnities and similar arrangements (including the payment of directors’ and officers’ insurance premiums), consulting fees, employee compensation, employee and director bonuses, employment agreements and arrangements or employee benefit arrangements, including, without limitation, stock options, stock awards, stock appreciation rights, performance awards, cash awards, legal fees or other benefits awarded under any employee incentive or similar compensation plan, as determined in good faith by Parent’s Board of Directors or senior management;

(2) any Restricted Payment that does not violate Section 4.07 or any Permitted Investment;

(3) loans and advances (or guarantees to third party loans) to directors, officers or employees of the Parent or any Restricted Subsidiary made in the ordinary course of business;

(5) the issuance of securities pursuant to, or for the purpose of the funding of, employment benefit arrangements, including, without limitation, stock options, stock awards, stock appreciation rights, performance awards, cash awards, legal fees or other benefits awarded under any employee incentive or similar compensation plan, as long as the terms thereof are or have been previously approved by the Parent’s or the relevant Restricted Subsidiary’s Board of Directors;

(6) transactions between or among the Parent and the Restricted Subsidiaries or between or among Restricted Subsidiaries;

(7) any transaction between or among: (i) the Parent and/or its Restricted Subsidiaries and (ii) any Joint Venture (where such Joint Venture is an Affiliate solely because the Parent and/or its Restricted Subsidiaries owns an equity interest in or otherwise controls such Joint Venture): (A) pursuant to the terms of the respective Joint Venture or other agreements, including but not limited to engineering, procurement and construction contracts, operation and maintenance contracts and other project agreements; (B) in the ordinary course of business in accordance with past practice; (C) pursuant to cash pooling or other similar arrangements; (D) consisting of an Investment; (E) which are fair to the Parent or the relevant Restricted Subsidiary, in the reasonable determination of Parent’s Board of Directors or senior management; or (F) which is on terms no less favorable than those that could reasonably have been obtained at such time from an unaffiliated Person, in the reasonable determination of Parent’s Board of Directors or senior management;

71

(8) any issuance of Equity Interests (other than Disqualified Stock) of the Parent;

(9) the existence of, or the performance by the Parent or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement relating thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Parent or any of its Restricted Subsidiaries of, obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (9) to the extent that the terms of any such amendment or new agreement, taken as a whole, are not disadvantageous to the Holders in any material respect;

(10) transactions with respect to which the Parent has obtained an opinion as to the fairness to Parent and its Restricted Subsidiaries from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing;

(11) transactions with (i) Unrestricted Subsidiaries or (ii) Joint Ventures in which the Parent or a Subsidiary of the Parent holds or acquires an ownership interest (whether by way of Capital Stock or otherwise), in each case so long as the terms of such transactions are, taken as a whole, at least as favorable to the Parent or the applicable Restricted Subsidiary as might reasonably have been obtained at such time from an unaffiliated party as determined by Parent’s Board of Directors or senior management;

(12) transactions between the Parent or any of its Restricted Subsidiaries and any Person that is an Affiliate solely as a result of the ownership by the Parent or any of the Restricted Subsidiaries of Capital Stock of such Person;

(13) transactions with Persons solely in their capacity as holders of Indebtedness of the Parent or any of its Restricted Subsidiaries where such Persons are treated no more favorably than holders of Indebtedness of the Parent or such Restricted Subsidiaries generally;

(14) Permitted Project Undertakings and Permitted Equity Commitments; and

(15) (i) pledges and other transfers of Equity Interests in Unrestricted Subsidiaries and (ii) any transactions with an Affiliate in which the consideration paid consists solely of Equity Interests of the Parent.

72

Section 4.12 Limitation on Liens.

The Parent will not, and will not permit any of its Restricted Subsidiaries to create, any Lien upon the whole or any part of the currently owned or after-acquired property of the Parent or any of its Restricted Subsidiaries or assets to secure any Indebtedness (other than Permitted Liens) unless in any such case, before or at the same time as the creation of the Lien, all amounts payable under the Notes are secured equally and ratably with such Indebtedness (until such time as such Indebtedness is no longer secured by such Lien). Any such Lien shall provide that it shall be released automatically upon repayment of the related Indebtedness.

Section 4.13 Maintenance of Cash Asset Coverage Ratio.

The Parent will maintain a Cash Asset Coverage Ratio of not less than 2.0 to 1.0 as of the last day of each fiscal quarter ending after the Issue Date.

Section 4.14 Existence.

Except as would not be prohibited under Article 5 and Section 10.04 hereof, the Issuer and each of the Guarantors shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate, limited liability company, partnership or other existence, as applicable.

Section 4.15 Offer to Repurchase Upon Change of Control Triggering Event.

(a) Upon the occurrence of a Change of Control Triggering Event, the Issuer will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (being not less than $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to the terms set forth in this Indenture.

(b) In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuer will deliver notice to each Holder (with a copy to the Trustee) stating that a Change of Control Offer is being made and offering to repurchase Notes on the date (the “Change of Control Payment Date”) specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is given, pursuant to the procedures required by this Indenture and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations 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 Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.15, the Issuer will comply with any applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance.

(c) On the Change of Control Payment Date, the Issuer 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

73

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

The Paying Agent will promptly cause to be delivered to each Holder properly tendered the Change of Control Payment for such Notes, and the Trustee (or its authenticating agent) will, upon receipt of an Authentication Order, promptly authenticate and deliver (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. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(d) The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of this Indenture are applicable.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of Parent may designate any Subsidiary of the Parent, other than the Issuer (including any newly acquired or newly formed Subsidiary or a Person becoming a Subsidiary through merger, consolidation or other business combination transaction, or Investment therein), to be an Unrestricted Subsidiary in accordance with the definition of “Unrestricted Subsidiary” and only if:

(1) such Subsidiary or any of its Subsidiaries does not own any Equity Interests or Indebtedness of, or own or hold any Lien on any property of, the Parent or any other Subsidiary of the Parent which is not a Subsidiary of the Subsidiary to be so designated or otherwise an Unrestricted Subsidiary; and

(2) such designation and the Investment of the Parent or any of the Restricted Subsidiaries in such Subsidiary complies with Section 4.07. Any such designation by the Board of Directors of Parent shall be evidenced to the Trustee by delivering to the Trustee a copy of the resolution of the Board of Directors of Parent giving effect to such designation and an Officer’s Certificate certifying that such designation complies with the foregoing conditions.

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 Parent as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Parent will be in default of such covenant. The Board of Directors of Parent may designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that immediately after giving effect to such designation (1) no Default or Event of Default would result therefrom and (2) the Parent could incur at least $1.00 of additional Indebtedness under Section 4.09(a) on a pro forma basis taking into account such designation. Any such designation by the Board of Directors of Parent shall be evidenced to the Trustee by promptly delivering to the Trustee a copy of the resolution of the Board of Directors giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the foregoing provisions.

Section 4.18 Covenant Fall Away.

If (i) a Rating Release Event has occurred and (ii) no Default or Event of Default has occurred and is continuing, then, beginning on that day, the Parent and its Restricted Subsidiaries shall be released from their respective obligations under the provisions of this Indenture described in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.16 and the provisions of clause (4) of the first paragraph of Section 5.01 and such provisions shall be terminated and permanently cease to have effect. In addition, after the conditions to termination of such covenants have been satisfied, the Parent may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17 and the definition of “Unrestricted Subsidiary.” The Issuer shall promptly give notice to the Trustee and provide the Trustee with an Officer’s Certificate stating that the conditions set forth in this Section 4.18 have been satisfied; provided that such notification shall not be a condition for the termination of the covenants described under this Section 4.18 to be effective. The Trustee shall be under no obligation to monitor the ratings of the Notes, determine, or verify the Issuer’s determination of, the satisfaction of the conditions set forth in this Section 4.18 or inform Holders of any of the foregoing.

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof with respect to the Parent or the Issuer, 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 30% in aggregate principal amount of the then outstanding Notes by written notice to the Issuer (with a copy to the Trustee if given by the Holders) may declare all the Notes to be due and payable immediately. 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 Parent and the Trustee may, on behalf of all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if all existing Events of Default (except nonpayment of principal of, premium on, if any, or interest, if any, on the Notes that has become due solely because of the declaration of acceleration) have been cured or waived.

In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (5) of Section 6.01 has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the Payment Default or other default triggering such Event of Default pursuant to such clause (5) of Section 6.01 shall be remedied or

79

cured, or waived by the holders of the Indebtedness with respect to which a Payment Default has occurred within 30 days after the declaration of acceleration of the Notes; provided that (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium on, if any, or interest, if any, on the Notes that became due solely because of the acceleration of the notes, have been cured or waived.

If a Default occurs for a failure to report or deliver a required certificate in connection with another default (an “Initial Default”) then at the time such Initial Default is cured, such Default for a failure to report or deliver a required certificate in connection with the Initial Default will also be cured without any further action and any Default or Event of Default for the failure to comply with the time periods prescribed in Section 4.03 or otherwise to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the delivery of any such report required by such covenant or notice or certificate, as applicable, even though such delivery is not within the prescribed period specified in this Indenture.

Section 6.03 Other Remedies.

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

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. 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 aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee

80

in personal liability (it being understood that the Trustee does not have an affirmative duty to determine if any action is prejudicial to any Holder). The Trustee may withhold from Holders notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest.

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 unless:

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

(2) Holders of at least 30% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

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

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

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

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

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

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium on, if any, and interest, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

81

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 allowed in any judicial proceedings relative to the Issuer (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 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

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

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

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

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee will mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary) to Holders of Notes a notice of the Default or Event of Default within the later of 90 days after it occurs or promptly after obtaining knowledge thereof. Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders.

Section 7.06 Compensation and Indemnity.

(a) The Issuer will pay to the Trustee from time to time compensation for its acceptance of this Indenture and services hereunder as agreed between the Issuer and the Trustee. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Issuer and the Guarantors will, jointly and severally, indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer and the Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to the Trustee’s own gross negligence or willful misconduct. The Trustee will notify the Issuer

86

promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer will not relieve the Issuer or any of the Guarantors of their obligations hereunder. The Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Issuer and the Guarantors under this Section 7.06 will survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

(d) To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.06, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium on, if any, interest, if any, on, particular Notes. 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 clause (8) or (9) of Section 6.01 hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.07 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 7.07.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.09 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.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

87

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition 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 7.09 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 Issuer. 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 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee.

Section 7.08 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.

Section 7.09 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 trust powers, 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.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuer may, at the option of its Board of Directors evidenced by a resolution set forth in an Officer’s Certificate, 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 Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer 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 Note Guarantees) on the date the conditions set

88

forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note 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 their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute such instruments reasonably requested by the Issuer 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, premium on, if any, or interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

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

(4) this Article 8.

Subject to compliance with this Article 8, the Issuer 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 Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of the 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 3.09, 4.03, 4.04, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 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 Note Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5), (6), and (7) hereof will not constitute Events of Default.

89

Section 8.04 Conditions to Legal or Covenant Defeasance.

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

(1) the Issuer 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, or interest and premium, if any, on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are being defeased to such Stated Maturity or to a particular redemption date (provided that if such redemption is made as provided under Section 3.07(c) (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Redemption Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money (a “Shortfall”) in trust on the redemption date as necessary to pay the Applicable Redemption Premium as determined on such date) (it being understood that any Legal Defeasance or Covenant Defeasance shall be subject to the condition subsequent that such Shortfall is in fact paid); provided, however, that the Trustee shall have no liability whatsoever in the event that such Shortfall is not in fact paid after any Legal Defeasance or Covenant Defeasance. Any Shortfall will be set forth in an Officer’s Certificate delivered to the Trustee at least two Business Days prior to the deposit of such Shortfall that confirms that such Shortfall will be applied toward such redemption);

(2) in the case of an election under Section 8.02 hereof, the Issuer shall deliver to the Trustee an Opinion of Counsel confirming that:

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

(B) since the Issue Date, there has been a change in the applicable 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 Issuer shall deliver to the Trustee an Opinion of Counsel 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;

90

(4) no Default or Event of Default shall have 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 any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(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 and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound;

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

(7) the Issuer 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 Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuer 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 Issuer from time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(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.

91

Section 8.06 Repayment to Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium on, if any, or interest, if any, on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer 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 Issuer.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 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 Issuer’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium on, if any, interest, if any, on, any Note following the reinstatement of its obligations, the Issuer 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, without the consent of any Holder, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees:

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

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

92

(3) to provide for the assumption of the Parent’s, the Issuer’s or any Subsidiary Guarantor’s obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Parent’s, the Issuer’s or such Subsidiary Guarantor’s assets;

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

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

(6) to conform the text of this Indenture or the Notes to any provision of the “Description of the Notes” section of the Issuer’s Offering Memorandum dated September 22, 2023, relating to the offering of the Initial Notes, as evidenced by an Officer’s Certificate to that effect;

(7) to evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee pursuant to the requirements thereof;

(8) to provide for or confirm the issuance of Additional Notes in accordance with this Indenture; or

(9) to provide for any Note Guarantee or to effect the release of a Guarantor from any its obligations under its Note Guarantee or this Indenture to the extent permitted hereby.

Upon the request of the Issuer, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Issuer 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 Issuer, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), 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 on, if any, or interest, if any, on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

93

Upon the request of the Issuer 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 Sections 7.02 and 9.05 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

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

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will mail (or, in the case of Global Notes, transmit in accordance with the procedures of the Depositary) to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail or transmit 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 Issuer or any Guarantor with any provision of this Indenture, the Notes or the Note 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 and provisions relating to the number of days of notice to be given in the event of a redemption);

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

(5) make any Note payable in currency 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, premium, if any, on, or interest, if any, on the Notes;

94

(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 from any of its obligations under its Note Guarantee or this Indenture other than in accordance with the terms of this Indenture; or

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

Section 9.03 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.04 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 Issuer 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 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors of the Issuer approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.02 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.

ARTICLE 10

NOTE GUARANTEES

Section 10.01 Note Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder 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 Issuer hereunder or thereunder, that:

(1) the principal of, premium, if any, on, and interest, if any, 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, premium on, if any, interest, if any, on, the Notes, if lawful, and all other obligations of the Issuer 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

95

(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 with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

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

96

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 Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, 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 Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture or, if applicable, a Supplemental Indenture in the form of Exhibit E, shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

Each Guarantor hereby agrees that its Note 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 Note Guarantee.

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

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

Section 10.04 Releases.

The Parent Guarantee will be released automatically:

(a) upon repayment in full of the Notes;

(b) upon the merger or consolidation of the Parent with and into the Issuer or upon the liquidation of the Parent following the transfer of all of its assets to the Issuer, in each case in compliance with the applicable provisions of this Indenture; or

(c) upon Legal Defeasance or satisfaction and discharge of the Notes as provided in Section 8.02 and Article 11.

97

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

98

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, if any, and interest, if any, to, but excluding, the date of maturity or redemption (provided that if such redemption is made as provided under Section 3.07(c), (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Redemption Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited the Shortfall in trust on the redemption date as necessary to pay the Applicable Redemption Premium as determined by such date) (it being understood that any satisfaction and discharge shall be subject to the condition subsequent that such Shortfall is in fact paid); provided, however, that the Trustee shall have no liability whatsoever in the event that such Shortfall is not in fact paid after any satisfaction and discharge of this Indenture. Any Shortfall will be set forth in an Officer’s Certificate delivered to the Trustee at least two Business Days prior to the deposit of such Shortfall that confirms that such Shortfall will be applied toward such redemption);

(2) in respect of subclause (b) of clause (1) of this Section 11.01, no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

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

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the provisions of Section 7.06 hereof and, 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 hereof, will survive.

99

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 Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, interest, if any, 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 Issuer’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 Issuer has made any payment of principal of, premium on, if any, or interest, if any, on, any Notes because of the reinstatement of its obligations, the Issuer 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.
