The Notes

2.01. Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be issued in minimum denominations of US$1,000 and integral multiples of US$1.00 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 Company, 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.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit 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. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the written direction of the Trustee, in accordance with written instructions given by the Holder thereof as required by Section 2.07 hereof.

2.02. Execution and Authentication. At least one Officer must sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid. A Note will not be valid until authenticated by the manual signature of a Responsible Officer of the

Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall, upon receipt of a written order of the Company signed by at least one Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.08 hereof.

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

2.03. Registrar and Paying Agent. The Company shall 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 registration of transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

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

2.04. Luxembourg Paying Agent and Luxembourg Transfer Agent. The Company has appointed Banque Internationale à Luxembourg S.A. as Luxembourg paying agent and Luxembourg transfer agent. The Company shall maintain such agencies so long as the Notes are listed on the Luxembourg Stock Exchange and the rules of the exchange so require.

2.05. Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest or Additional Amounts on the Notes, and shall notify the Trustee in writing of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as

Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

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

2.07. Transfer and Exchange.

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

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

(ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes representing the Notes; or

(iii) there has occurred and is continuing an Event of Default with respect to the Notes.

Upon the occurrence of any of the preceding events in subparagraphs (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee in writing. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08 and 2.11 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.07 or Sections 2.08 or 2.11 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.07(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.07(b) or (c) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. Beneficial interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the rules and procedures of the Depositary, Euroclear and Clearstream that apply

to such transfer or exchange. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.07(b).

(c) Transfer or Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.07(b) hereof, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.07(g) hereof, and the Company shall execute and the Trustee shall authenticate and deliver to the Person designated in the written instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.07(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through written instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Definitive Notes to the Persons in whose names such Notes are so registered.

(d) Transfer and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange such Definitive Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a written request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount at maturity of one of the Global Notes. If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to this Section 2.07(d) at a time when a Global Note has not yet been issued, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

(e) Transfer and Exchange of Definitive Notes for Definitive Notes. A Holder of Definitive Notes may transfer such Definitive Notes to a Person who takes delivery thereof in the form of a Definitive Note. Upon written request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.07(e), the Registrar shall register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing.

(f) Legends. The following legends will appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture.

(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 shall be returned to or retained and canceled by the Trustee in accordance with Section 2.12 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 shall 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.

(ii) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company or the Trustee 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 2.11, 3.06, 3.09, 4.10, 4.15 and 9.04 hereof).

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

(iv) Neither the Registrar nor the Company shall 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;

(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

2.08. Replacement Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, an Officers’ Certificate and an Opinion of Counsel, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company or the Trustee may charge for its expenses in replacing a Note.

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

2.09. 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 2.09 as not outstanding. Except as set forth in Section 2.10 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

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

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

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

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

2.12. Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, redemption, repurchase, replacement or cancellation in accordance with its internal procedures (subject to the record retention requirement of the Exchange Act). Upon the Company’s written request, certification of the cancellation of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

2.13. Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days

prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed or, if sent through DTC, send in accordance with DTC’s applicable procedures, to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

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

2.15. Ranking; Security for and Parity of Notes. All Notes issued and outstanding hereunder rank on a parity with each other Note, and each Note shall be secured equally and ratably by this Indenture and the Collateral Documents with each other Note, without preference, priority or distinction of any one thereof over any other by reason of difference in time of issuance or otherwise, and each Note shall be entitled to the same benefits and security in this Indenture and the Collateral Documents as each other Note. The Company shall be responsible for the continued maintenance, priority and perfection of such security interest as set forth in the Collateral Documents.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select Notes for redemption or purchase in compliance with the requirements of the principal securities exchange, if any, on which the Notes are listed, or if the Notes are not listed on a securities exchange, by lot or by such other method as the Trustee shall deem to be fair and appropriate and in accordance with DTC procedures.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in minimum amounts of US$1,000 and whole multiples of US$1.00 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of US$1.00, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

3.03. Notice of Redemption. Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed, by first-class mail or, if sent through DTC, send in accordance with DTC’s applicable procedures, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles VIII or XII hereof.

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

(a) the Redemption Date;

(b) the redemption price;

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

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

At the Company’s written request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 15 days (or such shorter period as agreed by the Trustee) prior to the date such notice of redemption is to be sent, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

3.04. Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price. A notice of redemption may not be conditional.

3.05. Deposit of Redemption or Purchase Price. On or before the Business Day prior to the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on, all Notes to be redeemed or purchased.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date and no additional interest will be paid to Holders whose Notes are redeemed. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

3.06. Notes Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased in part, the Company shall issue and, upon receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

3.07. Optional Redemption. (a) At any time and from time to time, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ written notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to the applicable Redemption Date, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest payment date.

(b) Unless the Company 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.

(c) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof; provided that, in the case of a redemption pursuant to Section 3.07, for the purposes of any notice required by Section 3.01 or 3.02, the redemption price may be stated to be “the redemption price determined in accordance with Section 3.07(a).”

3.08. Mandatory Redemption. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company may at any time and from time to time purchase Notes in the open market or otherwise.

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

The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and such 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 will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Company shall send, by first-class mail, 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 shall govern the terms of the Asset Sale Offer, will state:

(a) 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;

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

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

(e) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of US$1.00 only; provided that any unpurchased balance is in a minimum denomination of US$1,000 or an integral multiple of US$1.00 in excess of US$1,000;

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

(g) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the close of business on the second Business Day preceding 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;

(h) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Company shall 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 Company so that only Notes in minimum denominations of US$1,000, and integral multiples of US$1.00 in excess thereof, will be purchased); and

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

On or before the Purchase Date, the Company shall, 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 Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written request from the Company, 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 Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on the Purchase Date.

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

(x) the incurrence by the Company or any Restricted Subsidiary of Indebtedness consisting of performance and other similar bonds and reimbursement obligations Incurred by the Company or any Restricted Subsidiary securing the performance of contractual, franchise, concession or license obligations of the Company or a Restricted Subsidiary;

(xi) Attributable Debt with Respect to a Sale and Leaseback Transaction to the extent such Sale and Leaseback Transaction complies with the provisions under Section 4.20;

(xii) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business provided, however, that such Indebtedness is extinguished within five Business Days of incurrence;

(xiii) Indebtedness of the Company, to the extent the net proceeds thereof in their entirety are (i) used solely to purchase Notes tendered in a Change of Control Offer or (ii) concurrently deposited to defease the Notes as described under Article XII hereof;

(xiv) Indebtedness consisting of (i) the financing of insurance premiums or (ii) take or pay obligations in supply agreements, in each case in the ordinary course of business; and

(xv) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (xv), but excluding the indebtedness permitted by clauses (i) through (xiv), not to exceed US$20,000,000.

The Company shall not incur, and shall not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms.

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 of Permitted Debt described in clauses (i) through (xv) above or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall 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, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, the reclassification of accounts payable as Indebtedness and the payment of dividends on Disqualified Stock or preferred stock of Restricted Subsidiaries in the form of additional shares of the same class of Disqualified Stock or preferred stock of Restricted Subsidiaries will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock of Restricted Subsidiaries for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Consolidated Interest Expense of the Company as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

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

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

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

(1) the Fair Market Value of such assets at the date of determination; and

(2) the amount of the Indebtedness of the other Person.

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 calculated based on the relevant currency exchange rate determined as the average daily observed currency exchange rates reported by the Federal Reserve Bank of New York for the trailing 30 calendar day period, including the date of incurrence, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such refinancing indebtedness is denominated calculated based on the relevant currency exchange rates as calculated in the first sentence of this paragraph.

For the avoidance of doubt, the parties hereto acknowledge that the Junior PIK Notes to be issued on the date hereof and any PIK Interest (as defined in the indenture governing the Junior PIK Notes) thereon shall not be considered Indebtedness for purposes of this Indenture.

4.10. Asset Sales.

(a) Non-Collateral Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(i) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of as determined in good faith by the Company’s Board of Directors (including as to the value of all non-cash consideration); and

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

(A) Cash Equivalents;

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

(C) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 30 days following the closing of such Asset Sale, to the extent of the cash received in that conversion; and

(D) any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration previously received pursuant to this clause (D), not to exceed 1.0% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

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

(1) to permanently repay any Indebtedness, other than subordinated Indebtedness or any Indebtedness of a Subsidiary that is not a Guarantor and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

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

(3) to purchase long-term property or assets or make a capital expenditure used or useful in a Permitted Business.

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

(b) Collateral Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate a Collateral Asset Sale unless:

(i) the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of the Collateral Asset Sale at least equal to the Fair Market Value of such Collateral;

(ii) with respect to each such Collateral Asset Sale, the Company delivers an Officers’ Certificate to the Collateral Agent and the Trustee dated no more than 15 days prior to the date of consummation of the relevant Collateral Asset Sale, certifying that such sale complies with clause (a) above;

(iii) at least 75% of the consideration received for the Collateral sold by the Company or its Restricted Subsidiaries, as the case may be, shall be in the form of cash or Cash Equivalents received at the time of such Collateral Asset Sale; provided that any other consideration received for such Collateral shall constitute Collateral pursuant to appropriate Collateral Documents to which the owner thereof is a party; and

(iv) the Net Proceeds therefrom shall be paid directly by the purchaser thereof to the Collateral Agent, as additional Collateral.

In the case of any Collateral Asset Sale, the Company, within 360 days from the date of consummation of a Collateral Asset Sale, may apply all of the Net Proceeds therefrom to purchase or otherwise invest in Replacement Collateral. Any such Net Proceeds not so applied will be applied to make an Asset Sale Offer in accordance with the terms described under Section 3.09 hereof and this Section 4.10. In the case of a Collateral Asset Sale that represents all or substantially all of the Collateral, all of the Net Proceeds therefrom will be immediately applied to make an Asset Sale Offer in accordance with Section 3.09 hereof and this Section 4.10.

(c) Event of Loss. If the Company or a Restricted Subsidiary suffers an Event of Loss, the Net Proceeds therefrom will be paid directly by the party providing such Net Proceeds to the Collateral Agent, pursuant to the applicable Collateral Document, as additional Collateral. As any portion or all of the Net Proceeds from any such Event of Loss are received by the Collateral Agent, the Company may apply all of such amount or amounts, as received, together with all interest earned thereon, individually or in combination, (1) to purchase or otherwise invest in Replacement Collateral and (2) to restore the relevant Collateral. In the event that the Company elects to restore the relevant Collateral pursuant to the foregoing clause (2), within 180 days of receipt of such Net Proceeds from an Event of Loss, the Company shall:

(i) give the Trustee irrevocable written notice of such election, and

(ii) enter into a binding commitment to restore such Collateral, a copy of which will be supplied to the Trustee, and will have 360 days from the date of such binding commitment to complete such restoration, which will be carried out with due diligence. The Company shall take such action, at its sole expense, as may be required to ensure that the Collateral Agent has, from the date of such purchase or investment, a first ranking Lien on such Replacement Collateral.

Any such Net Proceeds that the Company does not elect to apply within such 180 day period or does not actually apply within such 360 day period will be applied to make an Asset Sale Offer in accordance with Section 3.09 hereof and this Section 4.10.

(d) Replacement Collateral. In the event that the Company decides pursuant to the foregoing provisions to apply any portion of the Net Proceeds from a Collateral Asset Sale or an Event of Loss to purchase or otherwise invest in Replacement Collateral:

(i) the Company shall deliver an Officers’ Certificate to the Collateral Agent and the Trustee dated no more than 30 days prior to the date of consummation of the relevant investment in Replacement Collateral, certifying that the purchase price for the amount of the investment in Replacement Collateral does not exceed the Fair Market Value of such Replacement Collateral;

(ii) the Company shall deliver an Officers’ Certificate to the Collateral Agent and the Trustee certifying compliance with the provisions of this Indenture and requesting the release of such certified purchase price to the Company (or the applicable Restricted Subsidiary), free of the Lien of the Collateral Documents; and

(iii) the Company shall take such actions, at its sole expense, as may be required to permit the Collateral Agent, pursuant to the applicable Collateral Document, to release such Net Proceeds, together with any interest thereon, from the Lien of the applicable Collateral Document and to ensure that the Collateral Agent has, from the date of such purchase or investment, a first-priority Lien on such Replacement Collateral pursuant to appropriate Collateral Documents.

Notwithstanding anything to the contrary in the foregoing, pending application of such consideration to acquire Replacement Collateral or restore the relevant Collateral in an Event of Loss, any consideration received in connection with a Collateral Asset Sale, an Event of Loss or an investment in Replacement Collateral shall be paid directly by the purchaser thereof to the Collateral Agent or otherwise constitute Collateral subject to a first-priority lien in form and substance satisfactory to the Collateral Agent.

(e) Asset Sale Offer. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of Section 4.10(a) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds US$5,000,000, within five days thereof, the Company shall make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at the offer price specified in the next sentence. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall select such other pari passu Indebtedness to be purchased on a pro rata basis in accordance with applicable depositary procedures. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent 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 Company shall 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.

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

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

(ii)

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of US$2,500,000, (1) the terms of the Affiliate Transaction are set forth in writing; (2) a majority of the disinterested members of the Board of Directors of the Company have determined in good faith that such Affiliate Transaction complies with this covenant and have approved such Affiliate Transaction; and (3) the Company delivers to the Trustee a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate evidencing the fulfillment of the condition set out in clause (ii)(A)(2); and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of US$6,000,000, in addition to the conditions set out in clause (ii)(A), the Company delivers to the Trustee a written opinion to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries issued by an investment banking firm of national standing.

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

(i) any reasonable and customary employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries and approved by the Board of Directors;

(ii) transactions exclusively between or among the Company and/or any of its Restricted Subsidiaries or exclusively between or among such Restricted Subsidiaries;

(iii) payment of reasonable directors’ fees to directors of the Company and its Restricted Subsidiaries who are not otherwise Affiliates of the Company as determined in good faith by the Company’s Board of Directors;

(iv) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;

(v) Restricted Payments that do not violate Section 4.07 hereof;

(vi) loans or advances to employees in the ordinary course of business and in accordance with the past practices of the Company or its Restricted

Subsidiaries, but in any event not to exceed US$500,000 in the aggregate at any time outstanding;

(vii) transactions with a Person that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person and no Affiliate of the Company (other than a Restricted Subsidiary thereof) owns any Equity Interests in, or controls, such Person except through their ownership of the Company; and

(viii) customary and reasonable transactions in connection with a Permitted Securitization, including Standard Securitization Undertakings.

4.12. Liens. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset or property of any character now owned or hereafter acquired by the Company or any of its Restricted Subsidiaries or any proceeds, income or profits therefrom, or assign or convey any right to receive income therefrom, except Permitted Liens.

4.13. Business Activities. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, engage, directly or indirectly, in any business other than Permitted Businesses.

4.14. Corporate Existence. Subject to Article V hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:

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

(b) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

4.15. Offer to Repurchase Upon Change of Control. (a) Upon the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to US$1,000 or integral multiples of US$1.00 above US$1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 10 days following the date on which a Change of Control occurs, the Company shall mail, by first-class mail, a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control and stating:

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

(ii) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

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

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

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

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

(vii) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to a minimum of US$1,000 in principal amount or an integral multiple of US$1.00 above US$1,000.

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

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

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

(ii) 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

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

The Paying Agent will promptly mail or, if sent through DTC, send in accordance with DTC’s applicable procedures (but in any event not later than five Business Days after the Change of Control Payment Date), to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Company shall not be required to make a Change of Control Offer upon a Change of Control (i) if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (ii) if a notice of redemption is given pursuant to Section 3.07 hereof and the redemption described therein is effected in accordance therewith.

4.16. Additional Note Guarantees; Additional Security. (a) If the Company or any of its Restricted Subsidiaries acquires or creates any direct or indirect Subsidiary after the date of this Indenture (a “New Subsidiary”), then the Company or such Restricted Subsidiary shall, within ten Business Days after such formation or acquisition, cause such New Subsidiary to:

(a) become a Guarantor and deliver to the Trustee a duly executed supplemental indenture and an Opinion of Counsel, each of which shall be in form and substance reasonably satisfactory to the Trustee, pursuant to which such New Subsidiary will unconditionally and irrevocably guarantee the Company’s obligations under the Notes, provided that any New Subsidiary that is designated as an Unrestricted Subsidiary need not become a Guarantor until five Business Days after as it ceases to be an Unrestricted Subsidiary; it being understood that such New Subsidiary shall take all required corporate actions and obtain all necessary authorizations to effect the valid execution and delivery of such supplemental indenture and any related documents; and

(b) duly execute and deliver to the Trustee and the Collateral Agent an Intercompany Subordination and Credit Agreement Supplement and an Intercompany Trust Agreement Supplement; it being understood that such New Subsidiary shall take all required corporate actions and obtain all necessary authorizations to effect the valid execution and delivery of such Intercompany Subordination and Credit Agreement Supplement and Intercompany Trust Agreement Supplement.

4.17. Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned

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

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

4.18. Listing. The Company shall use its best efforts to obtain and maintain listing of the Notes on the official list of the Luxembourg Stock Exchange and to maintain the Notes admitted to trading on the Euro MTF, the alternative market of the Luxembourg Stock Exchange; provided, however, that if the Company is unable to list the Notes on the Euro MTF, or if the Company is unable maintain its listing on the Euro MTF, it will use its best efforts prior to the delisting of the Notes to list and maintain a listing of the Notes on another internationally recognized stock exchange. In the event that a Restricted Subsidiary provides a Guarantee or is released from its obligations under a Guarantee at a time when the Notes are listed on the Euro MTF, the Company shall, to the extent required by the rules of the Luxembourg Stock Exchange, publish notice of the granting or release of such Restricted Subsidiary Guarantee on the website of the Luxembourg Stock Exchange, or in the Luxemburger Wort (with a copy of such notice to the Luxembourg Stock Exchange) and, in the case of the granting of a new Restricted Subsidiary Guarantee, deposit a copy of the Restricted Subsidiary Guarantee with the Luxembourg Stock Exchange and the Luxembourg Paying Agent.

4.19. Withholding Taxes. All payments under or in respect of the Notes or any Note Guarantee shall be made free and clear of, and without withholding or deduction for or on account of, any present or future taxes, duties, levies, imposts, assessments or governmental charges (including penalties, interest and additions related thereto) (collectively, “Taxes”) of

whatever nature imposed, levied, collected, withheld or assessed unless such withholding or deduction is required by law. In the event of any such withholding or deduction imposed or levied by a Tax Jurisdiction is required to be made from any payments under or with respect to the Notes or any Note Guarantee, the Company or the relevant Guarantor, as applicable, shall pay to Holders of the Notes such additional amounts (“Additional Amounts”) as will result in the net payment to such Holder (including Additional Amounts) of the amount that would otherwise have been receivable by such Holder in the absence of such withholding or deduction, except that no such Additional Amounts shall be payable with respect to:

(a) any Taxes that would not have been so withheld or deducted but for the Holder or Beneficial Owner of the Notes having a present or former connection to the relevant Tax Jurisdiction (including having a permanent establishment for tax purposes in such Tax Jurisdiction, being a citizen or resident or national of, incorporated in or carrying on a business, in the relevant Tax Jurisdiction in which such Taxes are imposed) other than the mere receipt of payments in respect of the Notes or any Note Guarantee, the mere holding or ownership of such Note or beneficial interest in the Note or the exercise of any rights under the Notes or this Indenture;

(b) where presentation is required for payment on a Note, any Taxes that would not have been so withheld or deducted if the Note had been presented for payment within 30 days after the Relevant Date, except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented on any day during such 30 day period and there were no additional withholdings or deductions as a result of such late presentment;

(c) any Taxes that would not have been so withheld or deducted but for the failure by the Holder or the Beneficial Owner of the Note or any payment in respect of such Note, after written request made to that Holder or Beneficial Owner at least 60 days before any such withholding or deduction would be payable, by the Company or the relevant Guarantor, the Trustee or the Paying Agent, as applicable, to comply with any certification, identification, information, documentation or other similar reporting requirement concerning its nationality, residence, identity or connection with the relevant Tax Jurisdiction, which is required or imposed by a statute, regulation or administrative practice of the relevant Tax Jurisdiction as a precondition to exemption from all or part of such Taxes;

(d) any estate, inheritance, gift, sales, transfer, personal property or similar Taxes imposed with respect to any Note;

(e) any Taxes payable other than by withholding or deduction;

(f) any withholding or deduction imposed on a payment to an individual that is required to be made pursuant to the European Union Directive on the taxation of savings income (the “Directive”) implementing the conclusions of the European Council of Economic and Finance Ministers (ECOFIN) meeting on June 3, 2003, or any law implementing or complying with, or introduced in order to conform to, such Directive;

(g) any Taxes imposed in connection with a Note presented for payment (where presentation is required) by or on behalf of a Holder or Beneficial Owner thereof who would have been able to avoid such tax by presenting the relevant Note to another paying agent; or

(h) any combination of (a) through (g) above.

Notwithstanding the foregoing, the limitations on the Company’s (or any relevant Guarantor’s, as applicable) obligation to pay Additional Amounts set forth in clauses (c) and (h) above shall not apply if (i) the provision of information, documentation or other evidence described in such clauses (c) and (h) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or Beneficial Owner of a Note (taking into account any relevant differences between U.S. and Mexican law rules, regulations or administrative practice) than comparable information or other reporting requirements imposed under U.S. tax law, regulation and administrative practice as of the Issue Date (such as IRS Forms W-8, W-8BEN and W-9) or (ii) Article 195, Section II of the Mexican Income Tax Law, or a substantially similar successor of such provision is in effect, unless the provision of the information, documentation or other evidence described in clauses (c) and (h) is expressly required by statute, regulation, or official administrative practice of general application in order to apply Article 195, Section II of the Mexican Income Tax Law, the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Article 195, Section II of the Mexican Income Tax Law. In addition, such clauses (c) and (h) shall not be construed to require a non-Mexican pension or retirement fund or a non-Mexican financial institution or another Holder to register with the Ministry of Finance and Public Credit (Servicio de Administración Tributaria) for the purpose of establishing eligibility for an exemption from or reduction of Mexican withholding tax or to require that a Holder or Beneficial Owner certify or provide information concerning whether it is or is not a tax-exempt pension or retirement fund.

If the Directive imposes taxes upon Notes, the Company shall use commercially reasonable efforts to maintain a paying agent with a specified office in a member state of the European Union that will not be obligated to withhold or deduct tax pursuant to the Directive or any law implementing or complying with, or introduced in order to conform to, the Directive.

References to principal, interest or any other amount payable on or in respect of any Note shall be deemed also to refer to any Additional Amounts which may be payable as set forth in this Indenture or in the Notes to the extent that Additional Amounts are, were or would be payable in respect thereof.

At least ten Business Days prior to the first interest payment date (and at least ten Business Days prior to each succeeding interest payment date if there has been any change with respect to the matters set forth in the below mentioned Officers’ Certificate), the Company or the relevant Guarantor, as applicable, will furnish to the Trustee and the Paying Agent an Officers’ Certificate instructing the Trustee and the Paying Agent whether payments of principal of or interest on the Notes due on such interest payment date shall be made without deduction or withholding for or on account of any Taxes by the Tax Jurisdictions (other than the jurisdiction where the Trustee is located or organized). If any such deduction or withholding shall be required, at least 20 days prior to such interest payment date (unless the obligation to pay

Additional Amounts arises after the 20th day prior to the payment date, in which case the Company or the relevant Guarantor shall notify the Trustee and the Paying Agent promptly thereafter), the Company, or the relevant Guarantor, as applicable, will furnish the Trustee and the Paying Agent with an Officers’ Certificate that specifies the amount, if any, required to be withheld on such payment to Holders of the Notes. If the Company or any Guarantor is obligated to pay Additional Amounts with respect to such payment, the Officers’ Certificate must also set forth any other information reasonably necessary to enable the Paying Agent to pay Additional Amounts to the Holders on the relevant payment date. For these purposes, any Officers’ Certificate required by this Indenture to be provided to the Trustee and the Paying Agent shall be deemed to be duly provided if telecopied to the Trustee and the Paying Agent.

The Company or the relevant Guarantor, as applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant tax authority in accordance with applicable law. The Company or the relevant Guarantor, as applicable, will obtain official receipts from each tax authority evidencing the payment of any Taxes so deducted or withheld, or, if such receipts are not obtainable, such other documentation reasonably acceptable to the Trustee. The Company, or the relevant Guarantor, as applicable, shall furnish to the Trustee the official receipts (or a certified copy of the official receipts or other such documentation, as applicable) evidencing payment of Taxes. The Company or the relevant Guarantor, as applicable, will attach to each certified copy or other such documentation, as applicable, a certificate stating (x) that the amount of such Tax evidenced by the certified copy was paid in connection with payments under or with respect to the Notes then outstanding upon which such Taxes were due and (y) the amount of such withholding tax paid per US$1.00 of principal amount of the Notes. Copies of such receipts or other such documentation, as applicable, shall be made available to Holders of the Notes upon written request.

The Company and the relevant Guarantor, as applicable, shall promptly pay when due, and indemnify the Holder for, any present or future stamp, issue, registration, court and/or documentary taxes, and/or any other excise taxes, similar charges or similar levies imposed by the Tax Jurisdictions on the execution, delivery, registration or enforcement of any of the Notes, this Indenture, any Guarantee or any other document or instrument referred to herein or therein.

4.20. Sale and Leaseback Transactions. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any Sale and Leaseback Transaction with respect to any property or assets unless:

(a) the Company or the Restricted Subsidiary, as applicable, would be entitled to:

(i) incur Indebtedness in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to Section 4.09; and

(ii) create a Lien on such property or assets securing such Attributable Debt pursuant to Section 4.12.

in which case, the corresponding Indebtedness and Lien will be deemed incurred pursuant to those provisions, and

(b) the Company complies with Section 4.10 hereof in respect of such transaction.

4.21. Limitation on the Sale or Issuance of Capital Stock of Restricted Subsidiaries. The Company:

(a) shall not, and shall not permit any Restricted Subsidiary to, sell, lease, transfer or otherwise dispose of any Capital Stock of any Restricted Subsidiary to any Person (other than the Company or a Wholly-Owned Restricted Subsidiary); and

(b) shall not permit any Restricted Subsidiary to issue any of its Capital Stock (other than, if necessary, shares of its Capital Stock constituting directors’ or other legally required qualifying shares) to any Person (other than to the Company or a Wholly-Owned Restricted Subsidiary), unless:

(i) immediately after giving effect to such issuance, sale or other disposition, neither the Company nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary;

(ii) immediately after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect thereto would have been permitted to be made under Section 4.07 if made on the date of such issuance, sale or other disposition; or

(iii) immediately after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would continue to constitute a Restricted Subsidiary and the Company or such Restricted Subsidiary applies the Net Proceeds of any such sale in accordance with Section 4.10 hereof.

4.22. No Impairment of Security Interests. Neither the Company nor any of its Restricted Subsidiaries will be permitted to take any action, or knowingly or negligently omit to take any action, which action or omission might or would have the result of materially impairing the security interest with respect to the Collateral for the benefit of the Collateral Agent, the Trustee and the Holders of the Notes, including the failure to obtain any required approval or any material defect in the creation, perfection or first-priority status of any Lien granted pursuant to the Collateral Documents. The Company shall cause the Restricted Subsidiaries to comply with their respective obligations under the Collateral Documents. The Company shall not amend, modify or supplement, or permit or consent to any amendment, modification or supplement of, the Collateral Documents in any way that would be adverse to the Holders of the Notes in any material respect, except as described under Article X hereof or as permitted under Article IX hereof.

4.23. Limitation on Intercompany Indebtedness.

(i) The Company shall, and shall cause its Subsidiaries, to cause all existing and future Intercompany Indebtedness (other than Ordinary Course Intercompany Indebtedness) to be subordinated to the Notes pursuant to the terms of the Intercompany Subordination and Credit Agreement and the Intercompany Trust Agreement, the terms of which, among other things, will provide that (i) no cash payments will be permitted to be made in respect of such Intercompany

Indebtedness while any of the Notes remain outstanding and (ii) all such Intercompany Indebtedness will be subordinated to the Notes in liquidation and in right of payment.

(ii) All existing and future Ordinary Course Intercompany Indebtedness will be incurred or deemed incurred pursuant to, and in accordance with the terms of, the Intercompany Subordination and Credit Agreement, the terms of which, among other things, will provide that (i) the Company and/or its Subsidiaries will be permitted to incur additional Ordinary Course Intercompany Indebtedness and make and collect payments in respect of such Ordinary Course Intercompany Indebtedness so long as such Ordinary Course Intercompany Indebtedness is incurred, and such payments are made or collected, in the ordinary course of business consistent with past practice and (ii) all such Ordinary Course Intercompany Indebtedness will be subordinated to the Notes in liquidation and in right of payment (subject to the preceding clause (i)).

(iii) During the pendency of any proceeding filed by or against the Company or any of its Subsidiaries seeking relief as debtor, or seeking to adjudicate the Company or any of its Subsidiaries as bankrupt or insolvent, or seeking reorganization, arrangement, adjustment or composition of the Company or any of its Subsidiaries or its debts under any law relating to bankruptcy, insolvency, reorganization, concurso mercantil, quiebra, or relief of debtors, or seeking appointment of a receiver, trustee, assignee, custodian, liquidator or visitador, conciliador or síndico or any other similar official for the Company or any of its Subsidiaries or for any substantial part of their property, the Company shall, and shall cause each of its Subsidiaries to, vote any claims that the Company or any Subsidiary of the Company might have based on Intercompany Indebtedness in the same manner as the majority of the unaffiliated third-party creditors of the Company and its Subsidiaries pursuant to the terms of the Intercompany Subordination and Credit Agreement and the Intercompany Trust Agreement.

(iv) Neither the Company nor any of its Subsidiaries will (i) enter into or maintain any Intercompany Indebtedness other than Intercompany Indebtedness under the Intercompany Subordination and Credit Agreement in accordance with the terms of this Section 4.23, or (ii) amend or waive any part of the documentation with respect to Intercompany Indebtedness in any way that would result in (x) a violation of this Indenture or the Collateral Documents or (y) a change of any kind in the provisions of such documentation relating to the subordination of the Intercompany Indebtedness.

(v) Upon the occurrence and during the continuation of an Event of Default, the Company shall not make any payment to any Subsidiary pursuant to the terms of any Intercompany Indebtedness and shall not take any action that could cause or result in such payment being made.

ARTICLE V

Successors

5.01. Merger, Consolidation, or Sale of Assets. The Company shall not, directly or indirectly: (1) consolidate, merge or reorganize with or into another Person (whether or not the Company is the surviving corporation); or (2) sell, assign, transfer, lease, convey or otherwise

dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

(d) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance or other disposition has been made would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable two-quarter period, (i) be permitted to incur at least US$1.00 of additional Indebtedness pursuant to the Leverage Ratio test set forth in Section 4.09(a) hereof or (ii) have a Leverage Ratio no greater than the Leverage Ratio of the Company immediately prior to giving effect to such transaction;

shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company and Issuer herein and shall be bound by all the terms and conditions of this Indenture, the Collateral Documents and all related agreements; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, in which case the predecessor Company shall be discharged from all of its obligations under this Indenture and the Notes.

ARTICLE VI

(a) default for 30 days in the payment when due of interest or any Additional Amounts on the Notes;

(b) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes;

(c) failure by the Company or any of its Restricted Subsidiaries to comply with the provisions of Sections 4.15 or 5.01 hereof;

(d) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other covenants or agreements in this Indenture;

(e) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default:

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

(ii) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates US$10,000,000 or more;

(f) failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of US$10,000,000, which judgments are not paid, discharged or stayed for a period of 60 days;

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

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

(i) commences a voluntary case,

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

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

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

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

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

(i) is for relief against the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case;

(ii) appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or

(iii) orders the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; and

(y) such order or decree remains unstayed and in effect for 60 consecutive days.

6.02. Acceleration. In the case of an Event of Default specified in clause (h) or (i) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company

that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare 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 Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except non-payment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived and the Company has paid or deposited, or caused to be paid or deposited, with the Trustee a sum sufficient to pay all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

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

6.04. Waiver of Defaults. Subject to Section 6.02, Holders of not less than 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 an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the 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.

6.05. Control by Majority. Holders of a majority in aggregate principal amount of the then outstanding Notes may, in writing, 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, in good faith as determined by a Responsible Officer of the Trustee, refuse to follow any direction that conflicts with applicable law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

6.06. Limitation on Suits. A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

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

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

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

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

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

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

6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) 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 Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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 all other amounts due to the Trustee pursuant to Section 7.07 hereof) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses,

disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof 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, in each case absent express authorization from such Holder. Notwithstanding the foregoing or any proof of claim that may have been filed by the Trustee, the parties hereto acknowledge and agree that the Holder or Beneficial Owner shall have the right to participate individually in any receivership, insolvency, liquidation, bankruptcy, reorganization, concurso mercantil, quiebra, arrangement, adjustment, composition, or other judicial proceeding relative to the Company or any Guarantor or the property of the Company or such Guarantor or their creditors, to the extent such participation is permissible under applicable law, and to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same in accordance with this Indenture.

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

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

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

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

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

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

Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

ARTICLE VII

Trustee

7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

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

(g) The Trustee shall not be deemed to have notice of a Default or an Event of Default unless (i) a Responsible Officer of the Trustee has actual knowledge thereof or (ii) the Trustee has received written notice thereof from the Company or any Holder at its Corporate Trust Office and such notice references this Indenture and the Notes.

(h) The permissive rights of the Trustee enumerated herein shall not be construed as duties.

(k) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

(n) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, if required, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign.

ARTICLE VIII

Legal Defeasance and Covenant Defeasance

8.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, 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 VIII.

8.02. Legal Defeasance and Discharge. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and all obligations of the Guarantors discharged with respect to their Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and

discharged the entire Indebtedness represented by the outstanding Notes (including the 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 (a) and (b) 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 Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, and any Additional Amounts that may be due and payable, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(b) the Company’s obligations with respect to such Notes under Article II and Section 4.02 hereof;

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

(d) this Article VIII.

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

8.03. Covenant Defeasance. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and 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 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.20, and 4.21 hereof and clause (d) 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 Company 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 shall 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 Company’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(c) and 6.01(d) hereof shall not constitute Events of Default.

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

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

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

8.04(a) 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.

8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company or the applicable Guarantor at its written request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease.

(h) evidence and provide for the acceptance of appointment by a successor Trustee.

Upon the written request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Collateral Agent and the Trustee of the documents described in Section 7.02 and Section 9.05 hereof, the Trustee shall join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but neither the Trustee nor the Collateral Agent shall be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

9.02. With Consent of Holders of Notes. Except as provided below in this Section 9.02, the Company, the Collateral Agent and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes 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 voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

Upon the written request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee and the Collateral Agent of evidence satisfactory to the Trustee and the Collateral Agent of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee and the Collateral Agent of the documents described in Section 7.02 and Section 9.05 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s or the Collateral Agent’s own rights, duties or immunities under this Indenture or otherwise, in which case each of the Trustee and the Collateral Agent may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

It is not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, 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 Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or 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):

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

(ii) reduce the principal of or change the fixed maturity of any Note or alter 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);

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

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

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

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

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

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

(ix) make any change in the ranking or priority of any Note that would adversely affect the Holders of the Notes in any material respect;

(xi) make any change in the provisions of this Indenture described under Section 4.19 hereof that adversely affects the rights of any Holder in any material respect, or amend the terms of the Notes or this Indenture in a way that would result in the loss of an exemption from any of the Taxes described hereunder;

(xii) make any change in the provisions of the Collateral Documents that would adversely affect the Holders of the Notes in any material respect; or

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

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

(b) The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid for more than 120 days after such record date.

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 Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

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

9.05. Trustee and Collateral Agent to Sign Amendments, Etc. The Trustee and the Collateral Agent, in each case, shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee or the Collateral Agent, as applicable. The Company may not sign an amended or supplemental indenture until the Board of Directors of the

Company approves it. In executing any amended or supplemental indenture, the Trustee and the Collateral Agent shall receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.05 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture (and any Notes issued in connection therewith) is the legal, valid and binding obligation of the Company and the Guarantors, as applicable, enforceable against the Company and the Guarantors, as applicable, in accordance with its terms.

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

Each of the Company and the Guarantors shall (i) enter into the Collateral Documents; (ii) within 10 Business Days of the Issue Date, take all necessary steps to duly file the Collateral Documents for registration in each relevant public registry in Mexico and promptly deliver to the Trustee and the Collateral Agent a copy of the original record of registration (constancia de inscripción) issued by the Mexican notary public; (iii) take any and all actions reasonably required to cause the Collateral Documents to create and maintain, as security for the Obligations of the Issuer and the Guarantors under the Notes, the Note Guarantees, the Collateral Documents and hereunder, a valid and enforceable perfected Lien in and on all of the Collateral, in favor of the Collateral Agent for the ratable benefit of the Holders, first in priority to any and all Liens at any time granted upon the Collateral, in each case, no later than 45 Business Days of the Issue Date; and (iv) deliver to the Trustee and the Collateral Agent a copy of the notarial instrument evidencing the registration of such Liens in each relevant public registry in Mexico. Each of the Trustee, the Company and the Guarantors hereby acknowledge and agree that the Collateral Agent shall hold the Collateral for the ratable benefit of the Holders and the Trustee pursuant and subject to the terms of the Collateral Documents. The Company and each Guarantor shall (A) deliver to the Trustee and the Collateral Agent copies of all documents required under the Collateral Documents to assure and confirm to the Trustee and the Collateral Agent that the security interests created in respect of the Collateral (or any part thereof) under the Collateral Documents constitute security for the Indenture and the Notes as contemplated in this Indenture, and (B) perform or cause their respective Subsidiaries to perform all such actions as may be required by the provisions of the Collateral Documents. Neither the Collateral Agent nor the Trustee shall be responsible for and neither of them make any representation as to the existence, genuineness, value or protection of any Collateral, or the legality, effectiveness or sufficiency of any Collateral Document, or for the creation, perfection, priority, sufficiency or protection of any liens securing the Notes. For the avoidance of doubt, nothing herein shall require the Collateral Agent or the Trustee to file financing statements or continuation statements or local filings required by Mexican law or be responsible for perfecting or maintaining the perfection of security interests purported to be created as described herein (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder or under any other Collateral Document) and such responsibility shall be solely that of the Company.

10.02. Use of the Collateral. Subject to the terms and conditions of the Collateral Documents and this Indenture, the Company shall be entitled, unless an Event of Default has occurred and is continuing and the Collateral Agent has given contrary instructions in accordance with the terms of the Collateral Documents, to generally remain in possession of and to retain exclusive control over the Collateral (other than any amounts that are the proceeds of a Collateral Asset Sale or an Event of Loss relating to the Collateral), to freely operate the Collateral, to replace the Collateral and to sell or otherwise dispose of Collateral (including, with respect to cash constituting Collateral by virtue of being proceeds under any mortgage), and to collect, invest and dispose of any income in respect of any Collateral, in each case in the ordinary course of the Company’s business.

10.03. Determinations Relating to Collateral. In the event (a) the Collateral Agent shall receive any written request from the Company for consent or approval with respect to any matter or thing relating to the Collateral or the Company’s obligations with respect thereto or (b) there

shall be due to or from the Collateral Agent under the provisions of the Collateral Documents any material performance or the delivery of any material instrument or (c) a Responsible Officer of the Collateral Agent shall become actually aware of any material nonperformance by the Company or any Guarantor of any covenant or any material breach of any representation or warranty of the Company or a Guarantor set forth in the Collateral Documents, then, in each such event, the Collateral Agent shall be entitled to hire, at the sole reasonable cost and expense of the Company, experts, consultants, agents and attorneys to advise the Collateral Agent on the manner in which the Collateral Agent should respond to such request or render any requested performance or response to such nonperformance or breach.

10.04. Suits to Protect the Collateral. Subject in all respects to the terms and conditions of the Collateral Documents, the Collateral Agent shall have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of this Indenture, the Collateral Documents, and such suits and proceedings as the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral Documents and in the principal, interest, issues, profits, rents, revenues and other income arising therefrom, including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid, if the enforcement of, or compliance with, such enactment, rule or order would impair the security hereunder or under the Collateral Document, or be prejudicial to the interests of the Holders, the Trustee or the Collateral Agent.

10.05. Termination and Reinstatement of the Collateral. Upon the full and final payment and performance by the Company and the Guarantors of the Obligations under the Notes, this Indenture and the Collateral Documents, the Collateral Documents will terminate and the Liens on all of the Collateral will be released. The Collateral Agent shall release the Liens in favor of it in any Collateral to be sold pursuant to a Collateral Asset Sale or, in the case of certain obsolete or other assets, to be disposed of in a transaction not considered a Collateral Asset Sale pursuant to clause (i) of the exclusion to the definition thereof; provided that such transaction shall be subject to the provisions under Section 4.10 hereof.

10.06. Enforcement and Disposition of Collateral. (a) Upon the occurrence and during the continuation of an Event of Default:

(i) the Collateral Agent shall be entitled to cancel any lease agreement entered into by each Restricted Subsidiary owning real property subject to a mortgage; and

(ii) the Collateral Agent may, without notice, enter upon all or any portion of the Company’s and its Restricted Subsidiaries’ premises that comprises the Collateral to inspect the Collateral and may exercise other rights with respect to the Collateral under applicable law.

(b) For so long as an Event of Default has occurred and is continuing, except as otherwise provided in the Collateral Documents or this Indenture, the Collateral Agent may be directed in writing by the Holders of the Notes, through the Trustee, to take (or to refrain from

taking) such action or exercise such power only upon the written instruction of the Holders of at least 25% in aggregate principal amount of the Notes then outstanding and if such Holders have offered to the Collateral Agent indemnity or security satisfactory to it against any loss, liability or expense, and provided always that if the Collateral Agent receives conflicting instructions, those supported by Holders representing a greater aggregate principal amount will prevail.

(c) The cash proceeds of sales of, or collections on, any Collateral received upon the exercise of remedies, including pursuant to a bankruptcy proceeding, will be applied pursuant to the Collateral Documents in the following order of priority:

(i) first, to the payment of all unpaid fees, expenses, reimbursements, indemnifications and advancements of the Collateral Agent and its agents and counsel under the Collateral Documents to the unpaid fees, expenses, reimbursements and indemnifications of the Collateral Agent and to the payment of all unpaid fees, expenses, reimbursements, indemnifications and advancements of the Trustee and its agents and counsel, to the extent relating to their activities in connection with the Collateral Documents;

(ii) second, to the payment of principal under the Notes, excluding any premium, interest, penalty or other amounts in respect thereof, on a pro rata basis and subject to the limitations provided below;

(iii) third, to the payment of accrued and unpaid interest under the Notes;

(iv) fourth, to the payment of any other Obligations under the Notes; and

(vi) fifth, to the Company and its Restricted Subsidiaries or to whomever else may lawfully be entitled to receive such proceeds or as a court of competent jurisdiction may direct.

10.07. Collateral Documents. This Article X and the provisions of each Collateral Document are subject to the terms, conditions and benefits set forth in the Collateral Documents in all respects. The Company and each Guarantor consent to, and agree to be bound by, the terms of the Collateral Documents, as the same may be in effect from time to time, and to perform their respective obligations thereunder in accordance therewith.

10.08. Collateral Agent. (a) At the direction of the Holders of the Notes, the Trustee shall appoint a collateral agent, which shall be authorized to act on behalf of and for the benefit of the Holders of the Notes. In accordance with the foregoing, on the Issue Date, CIBanco, S.A., Institución de Banca Múltiple is hereby appointed by the Trustee, at the direction of the Holders of the Notes, to serve as Collateral Agent for the benefit of the Holders of the Notes.

(b) The Collateral Agent appointed by the Trustee as provided in Section 10.08(a) hereof shall be the secured party of record with respect to the security interests created in respect of the Collateral under the Collateral Documents and shall hold such Collateral for the benefit of the Holders of the Notes.

(c) The Collateral Agent shall hold (directly or through co-agents), and shall be entitled to enforce, all Liens on the Collateral created by the Collateral Documents in accordance with the terms of the Collateral Documents. Neither the Company or any of the Guarantors nor their respective Affiliates may serve as Collateral Agent.

(d) Except as provided in the Collateral Documents, the Collateral Agent shall not be obligated to: (i) act upon directions purported to be delivered to it by any Person; (ii) foreclose upon or otherwise enforce any Lien; or (iii) take any other action whatsoever pursuant to any or all of the Collateral Documents, the Liens created thereby or the Collateral.

(e) A resignation or removal of the Collateral Agent and appointment of a successor Collateral Agent will become effective pursuant to the terms of the Collateral Documents.

(f) The Collateral Agent shall be entitled to all the rights, protections, privileges and immunities granted to the Trustee under this Indenture. Whenever reference is made in this Indenture or the Collateral Documents to any action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral Agent, it is understood that in all cases the Collateral Agent shall be acting, giving, withholding, suffering, omitting, taking or otherwise undertaking and exercising the same (or shall not be undertaking and exercising the same) as directed by the Trustee. This provision is intended solely for the benefit of the Collateral Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto.

(g) The duties of the Collateral Agent shall be mechanical and administrative in nature. The Collateral Agent shall not have, by reason hereof or any of the Collateral Documents, a fiduciary relationship with any Holder, the Company, any Guarantor or any other Person, and nothing herein or in any of the Collateral Documents, inferred or implied, is intended to or shall be so construed as to impose upon the Collateral Agent any duties, responsibilities or obligations in respect hereof or of any of the Collateral Documents, except as expressly set forth herein or therein.

10.09. Release of Liens in Respect of the Notes. The Collateral Agent’s priority Liens upon the Collateral shall no longer secure the Notes outstanding under this Indenture, the Note Guarantees or any other Obligations under this Indenture, and the right of the Holders of the Notes and such Obligations to the benefits and proceeds of the Collateral Agent’s priority Liens on the Collateral shall terminate and be discharged, in which case the Collateral Agent shall sign and permit the Company to file all required documents provided to it, at the Company’s sole cost and expense, to effectuate the release of the Collateral Agent’s Liens upon the Collateral upon the receipt by the Collateral Agent from the Trustee of written notice as to any of the following:

(a) satisfaction and discharge of this Indenture, in accordance with Article XII hereof;

(b) Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article VIII hereof;

(c) payment in full and discharge of all Notes outstanding under this Indenture and all Obligations that are outstanding, due and payable under this Indenture at the time the Notes are paid in full and discharged (other than any obligations for taxes, costs, indemnifications, reimbursements, damages and other liabilities in respect of which no claim or demand for payment has been made at such time); or

(d) such termination or discharge, in whole or in part, with the consent of the Holders of the requisite percentage of Notes in accordance with Article IX hereof;

10.10. Relative Rights. Nothing in this Indenture or the Collateral Documents will:

(b) affect the relative rights of Holders as against any other creditors of the Company or any Guarantor (other than Permitted Liens);

ARTICLE XI

Note Guarantees

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

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

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

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

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this 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 Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

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

11.02. 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 XI, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

11.03. Execution and Delivery of Note Guarantee. To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit B hereto will be endorsed by an Officer of such Guarantor by manual or facsimile signature on each Note authenticated and delivered by the Trustee in accordance with this Indenture and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

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

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

In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Subsidiary after the date of this Indenture, if required by Section 4.16 hereof, the Company shall cause such Restricted Subsidiary to comply with the provisions of Section 4.16 hereof and this Article XI, to the extent applicable.

11.04. Guarantors May Consolidate, Etc., on Certain Terms. Except as otherwise provided in Section 11.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

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

(b) either:

(i) subject to Section 11.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee on the terms set forth herein or therein pursuant to a supplemental indenture in form and substance satisfactory to the Trustee; or

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

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

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

11.05. Releases. The Note Guarantee of a Guarantor will be released:

(a) in the event of any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company otherwise permitted by this Indenture;

(b) in the event of any sale or other disposition of all of the Capital Stock of that Guarantor owned by the Company and its subsidiaries to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company otherwise permitted by this Indenture;

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

(d) upon Legal Defeasance or satisfaction and discharge of this Indenture in accordance with Articles VIII and XII hereof, respectively.

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee shall execute any documents reasonably requested by the Company in writing in order to evidence the release of the Guarantor from its obligations under its Note Guarantee.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article XI.

ARTICLE XII

Satisfaction and Discharge

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

(a) either:

(i) 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 heretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

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

(b) 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 the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

(d) the Company 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 Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section 12.01, the provisions of Sections 8.06 and 12.02 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

12.02. Application of Trust Money. Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

ARTICLE XIII

Miscellaneous

13.01. Currency Indemnity. U.S. dollars are the sole currency of account and payment for all sums payable by the Company or the Guarantors under or in connection with the Notes, including damages. To the greatest extent permitted under applicable law, any amount received or recovered in a currency other than dollars (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the winding up or dissolution of the Company or the Guarantors or otherwise) by any Holder of a Note in respect of any sum expressed to be due to it from the Company or the Guarantors shall constitute a discharge to the Company or the Guarantors only to the extent of the dollar amount which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If that dollar amount is less than the dollar amount expressed to be due to the recipient under any Note, the Company or the Guarantors shall indemnify the recipient against any loss sustained by it as a result. In any event, the Company or the Guarantors shall

indemnify the recipient against the cost of making any such purchase. For the purposes of this Section 13.01, it will be sufficient for the Holder of a Note to certify in a satisfactory manner (indicating the sources of information used) that it would have suffered a loss had an actual purchase of dollars been made with the amount so received or recovered in that other currency on the date of receipt or recovery (or, if a purchase of dollars on such date had not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of date be certified in the manner mentioned above). These indemnities constitute a separate and independent obligation from the other obligations of the Company or the Guarantors, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any Holder of a Note and shall constitute in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note.

13.02. Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA §318(c), the duties imposed by the TIA will control.

13.03. Notices. Any notice or communication by the Company, any Guarantor or the Trustee to the others is duly given if in writing and delivered in Person or by first-class mail (registered or certified, return receipt requested), facsimile transmission, .pdf attached to an email or overnight air courier guaranteeing next day delivery, to the others’ address:

If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in writing in its exercise of any trust or power.

The Trustee may, in good faith as determined by a Responsible Officer of the Trustee, refuse to

A-7

follow any direction that conflicts with applicable law or the Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 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, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal, interest or premium, if any, on the Notes.

(13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. However, if the Trustee acquires any conflicting interest, it must eliminate such conflict within 90 days and, if required, apply to the SEC for permission to continue as Trustee (if the Indenture has been qualified under the TIA) or resign.

(14) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator or stockholder of the Company or any of Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

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

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture, dated as of [ ], 2019 (the “Indenture”) providing for the issuance of 8% Senior Secured Notes due 2024 (the “Notes”);
