The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

(c) Except as provided below, owners of beneficial interests in Global Notes shall not be entitled to receive Certificated Notes. Global Notes shall be exchangeable for Certificated Notes only in the following limited circumstances:

(i) DTC notifies the Company that it is unwilling or unable to continue as depositary for such Global Note or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice;

(ii) the Company executes and delivers to the Trustee and Registrar an Officers’ Certificate stating that such Global Note shall be so exchangeable; or

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

In connection with the exchange of an entire Global Note for Certificated Notes pursuant to this Section 2.7(c), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon Company Order the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations.

Section 2.8 Legends.

(a) Each Global Note shall bear the legend specified therefor in Exhibit A on the face thereof.

(b) Each Restricted Note shall bear the private placement legend specified therefor in Exhibit A on the face thereof (the “Private Placement Legend”).

Section 2.9 Transfer and Exchange.

The following provisions shall apply with respect to any proposed transfer of an interest in a Rule 144A Global Note that is a Restricted Note:

(a) If (1) the owner of a beneficial interest in a Rule 144A Global Note wishes to transfer such interest (or portion thereof) to a Non-U.S. Person pursuant to Regulation S and (2) such Non-U.S. Person wishes to hold its interest in the Notes through a beneficial interest in the Regulation S Global Note, subject to the rules and procedures of DTC, upon receipt by the Note Custodian and Registrar of:

(i) instructions from the Holder of the Rule 144A Global Note directing the Note Custodian and Registrar to credit or cause to be credited a beneficial interest in the Regulation S Global Note equal to the principal amount of the beneficial interest in the Rule 144A Global Note to be transferred; and

(ii) a certificate in the form of Exhibit C from the transferor,

the Note Custodian and Registrar shall increase the Regulation S Global Note and decrease the Rule 144A Global Note by such amount in accordance with the foregoing.

(b) If the owner of an interest in a Regulation S Global Note wishes to transfer such interest (or any portion thereof) to a QIB pursuant to Rule 144A prior to the expiration of the Distribution Compliance Period therefor, subject to the rules and procedures of DTC, upon receipt by the Note Custodian and Registrar of:

(i) instructions from the Holder of the Regulation S Global Note directing the Note Custodian and Registrar to credit or cause to be credited a beneficial interest in the Rule 144A Global Note equal to the principal amount of the beneficial interest in the Regulation S Global Note to be transferred; and

(ii) a certificate in the form of Exhibit B duly executed by the transferor,

the Note Custodian and Registrar shall increase the Rule 144A Global Note and decrease the Regulation S Global Note by such amount in accordance with the foregoing.

(c) Other Transfers. Any transfer of Restricted Notes not described in Section 2.9 (other than a transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a Certificated Note or a beneficial interest in another Global Note, which must be effected in accordance with applicable law and the rules and procedures of DTC, but is not subject to any procedure required by this Indenture) shall be made only upon receipt by the Registrar of such opinions of counsel, certificates and/or other information reasonably required by and satisfactory to it in order to ensure compliance with the Securities Act or in accordance with Section 2.9(d).

(d) Use and Removal of Private Placement Legends. Upon the registration of transfer, exchange or replacement of Notes (or beneficial interests in a Global Note) not bearing (or not required to bear upon such registration of transfer, exchange or replacement) a Private Placement Legend, the Note Custodian and Registrar shall exchange such Notes (or beneficial interests) for beneficial interests in a Global Note (or Certificated Notes if they have been issued pursuant to Section 2.7(c)) that does not bear a Private Placement Legend. Upon the transfer, exchange or replacement of Notes (or beneficial interests in a Global Note) bearing a Private Placement Legend, the Note Custodian and Registrar shall deliver only Notes (or beneficial interests in a Global Note) that bear a Private Placement Legend unless:

(i) such Notes (or beneficial interests) are transferred pursuant to Rule 144 upon delivery to the Registrar of a certificate of the transferor in the form of Exhibit D and an Opinion of Counsel reasonably satisfactory to the Registrar;

(ii) such Notes (or beneficial interests) are transferred, replaced or exchanged after the Resale Restriction Termination Date therefor;

(iii) a transfer of such Notes is made pursuant to an effective Shelf Registration Statement, in which case the Private Placement Legend shall be removed from such Note so transferred at the request of the Holder, or the Initial Notes are exchanged for Exchange Notes pursuant to the provisions of the Registration Rights Agreement; or

(iv) in connection with such registration of transfer, exchange or replacement the Registrar shall have received an Opinion of Counsel and other evidence reasonably satisfactory to it to the effect that neither such Private Placement Legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

The Private Placement Legend on any Note shall be removed at the request of the Holder on or after the Resale Restriction Termination Date therefor. The Holder of a Global Note may exchange an interest therein for an equivalent interest in a Global Note not bearing a Private Placement Legend (other than a Regulation S Global Note) upon transfer of such interest pursuant to any of clauses (i) through (iv) of this Section 2.9(d).

(e) Consolidation of Global Notes. Nothing in this Indenture shall provide for the consolidation of any Notes with any other Notes to the extent that they constitute, as determined pursuant to an Opinion of Counsel, different classes of securities for U.S. federal income tax purposes.

(f) Retention of Documents. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Article II. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

(i) Subject to the other provisions of this Section 2.9 when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar or co-Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided that any Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and to the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfers and exchanges and subject to the other terms and conditions of this Article II, the Company shall execute and upon Company Order the Trustee shall authenticate Certificated Notes and Global Notes at the Registrar’s or co-Registrar’s request.

(ii) No service charge shall be made to a Holder 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, assessment, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer pursuant to Section 3.7 or Section 3.10.

(iii) The Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Note for a period beginning: (1) 15 days before the mailing of a notice of an offer to repurchase or redeem Notes and ending at the close of business on the day of such mailing; or (2) 15 days before an Interest Payment Date and ending on such Interest Payment Date.

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

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

(h) No Obligation of the Trustee.

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

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

Section 2.10 Mutilated, Destroyed, Lost or Stolen Notes.

(a) If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall execute and upon Company Order the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code of the State of New York are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an affidavit of loss and indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-Registrar from any loss that any of them may suffer if a Note is replaced, and, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code of the State of New York), the Company shall execute and upon Company Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously Outstanding.

(b) Upon the issuance of any new Note under this Section 2.10, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Company’s counsel, the Trustee and its counsel) in connection therewith.

(c) In case any mutilated, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company may, in its discretion, pay such Notes instead of issuing a new Note in replacement thereof.

(d) Every new Note issued pursuant to this Section 2.10 in exchange for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, shall constitute an original additional contractual obligation of the Company and any other obligor upon the Notes, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

(e) The provisions of this Section 2.10 shall be exclusive and shall be in lieu of, to the fullest extent permitted by applicable law, all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 2.11 Temporary Notes. Until definitive Notes are ready for delivery, the Company may execute and upon Company Order the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and execute and upon Company Order the Trustee shall authenticate definitive Notes. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and upon Company Order the Trustee shall authenticate and make available for delivery in exchange therefor one or more definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall in all respects be entitled to the same benefits under this Indenture as a Holder of definitive Notes.

Section 2.12 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of cancelled Notes in accordance with its customary procedures or return to the Company all Notes surrendered for registration of transfer, exchange, payment or cancellation. Subject to Section 2.10, the Company may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange upon Company Order.

Section 2.13 Defaulted Interest. When any installment of interest becomes Defaulted Interest, such installment shall forthwith cease to be payable to the Holders in whose names the

Notes were registered on the Record Date applicable to such installment of interest. Defaulted Interest (including any interest on such Defaulted Interest) may be paid by the Company, at its election, as provided in Section 2.13(a) or Section 2.13(b).

(a) The Company may elect to make payment of any Defaulted Interest (including any interest on such Defaulted Interest) to the Holders in whose names the Notes are registered at the close of business on a special record date for the payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest as provided in this Section 2.13(a). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 calendar days and not less than ten calendar days prior to the date of the proposed payment and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be sent, first-class mail, postage prepaid, to each Holder at such Holder’s address as it appears in the registration books of the Registrar, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Holders in whose names the Notes are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to Section 2.13(b).

(b) Alternatively, the Company may make payment of any Defaulted Interest (including any interest on such Defaulted Interest) in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 2.13(b) such manner of payment shall be deemed practicable by the Trustee.

Section 2.14 Additional Notes. The Company may, from time to time, subject to compliance with any other applicable provisions of this Indenture, without the consent of the Holders, create and issue pursuant to this Indenture Additional Notes having terms and conditions set forth in Exhibit A identical to those of the Initial Notes, except that Additional Notes:

(a) may have a different issue price, issue date and, if applicable, date from which the interest shall accrue from the Initial Notes;

(b) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on the Initial Notes; and

(c) may have terms specified in the Additional Note Board Resolution or Additional Note Supplemental Indenture for such Additional Notes making appropriate adjustments to this Article II and Exhibit A (and related definitions) applicable to such Additional Notes in order to conform to and ensure compliance with the Securities Act (or other applicable securities laws), which are not adverse in any material respect to the Holder of any Outstanding Notes (other than such Additional Notes);

provided that no Additional Notes shall constitute a different class of securities than the Initial Notes for U.S. federal income tax purposes, except for Additional Notes that have a separate CUSIP number from such Initial Notes.

(a) The Company shall pay the principal of and interest (including Defaulted Interest) on the Notes in U.S. Dollars on the dates and in the manner provided in the Notes and in this Indenture. Prior to 11:00 a.m. (New York City time) on the Business Day prior to each Interest Payment Date and the Maturity Date, the Company shall deposit with the Paying Agent in immediately available funds U.S. Dollars sufficient to make cash payments due on such Interest Payment Date or Maturity Date, as the case may be. If the Company or an Affiliate of the Company is acting as Paying Agent, the Company or such Affiliate shall, prior to 11:00 a.m. (New York City time) on each Interest Payment Date and the Maturity Date, segregate and hold in trust U.S. Dollars sufficient to make cash payments due on such Interest Payment Date or Maturity Date, as the case may be. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent (other than the Company or an Affiliate of the Company) holds in accordance with this Indenture U.S. Dollars designated for and sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. Notwithstanding the foregoing, the Company may elect to make the payments of interest by check mailed to the registered Holders at their registered addresses.

(b) If a Holder of Notes in an aggregate principal amount of at least U.S.$1,000,000 has given wire transfer instructions to the Company, the Company shall make all principal and interest payments on those Notes in accordance with such instructions.

(b) The Company may also from time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in The City of New York or, so long as the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market, and the rules of such Exchange so require, in Luxembourg, for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

Section 3.3 Corporate Existence. Subject to Article IV, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 3.5 Further Instruments and Acts. The Company and each Subsidiary Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper or as may be required by applicable law to carry out more effectively the purpose of this Indenture.

Section 3.6 Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants (to the fullest extent permitted by applicable law) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company or such Subsidiary Guarantor from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture. The Company and each Subsidiary Guarantor hereby expressly waives (to the fullest extent

permitted by applicable law) all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

Section 3.7 Change of Control.

(a) Upon the occurrence of a Change of Control, the Company shall make an offer to purchase Notes (the “Change of Control Offer”), pursuant to which the Company shall be required, if requested by any Holder, to purchase all or a portion (in integral multiples of U.S.$1,000, provided that the principal amount of such Holder’s Note shall not be less than U.S.$100,000) of such Holder’s Notes at a purchase price equal to 101% of the principal amount thereof, plus any accrued and unpaid interest thereon through the purchase date (the “Change of Control Payment”).

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

(i) accept for payment all Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer;

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

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

(c) If only a portion of a Note is purchased pursuant to a Change of Control Offer, a new Note in a principal amount equal to the portion thereof not purchased shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate). Notes (or portions thereof) purchased pursuant to a Change of Control Offer shall be cancelled and cannot be reissued.

(d) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations thereunder in connection with the purchase of Notes in connection with a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 3.7, the Company shall comply with such securities laws and regulations and shall not be deemed to have breached its obligations under this Indenture by doing so.

(e) The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in compliance with the conditions and requirements of this Indenture and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

(f) The provisions of this Section 3.7 shall be applicable whether or not any other provisions of this Indenture are applicable. The obligation of the Company to make an

(d) 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 non-U.S. currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred or, in the case of revolving credit Indebtedness, first committed; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a non-U.S. currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 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 that is in effect on the date of such refinancing.

(1) 50% of cumulative Consolidated Net Income of the Company or, if such cumulative Consolidated Net Income of the Company is a loss, minus 100% of the loss, accrued during the period, treated as one accounting period, from the beginning of the fiscal quarter in which the Issue Date occurs to the end of the most recent fiscal quarter for which consolidated financial information of the Company is available; plus

(2) 100% of the aggregate net cash proceeds received by the Company from any Person from any contribution to the Capital Stock of the Company not representing an interest in Disqualified Capital Stock or issuance and sale of Qualified Capital Stock of the Company, in each case subsequent to the Issue Date; or

(3) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the conversion or exchange subsequent to the Issue Date of any Indebtedness for borrowed money of the Company or any Restricted Subsidiary for Qualified Capital Stock of the Company (less the amount of any cash, or the Fair Market Value of any other property, distributed by the Company upon such conversion or exchange);

(4) 100% of the aggregate net cash proceeds received by the Company upon the sale, liquidation or repayment of any Investment or, in the case of a Guarantee, the amount of the Guarantee upon the unconditional release of the Company and its Restricted Subsidiaries in full, less any payments previously made by the Company or any Restricted Subsidiary in respect of such Guarantee; and

(5) in the case of a Revocation of the Designation of an Unrestricted Subsidiary, an amount equal to the lesser of:

(ii) the acquisition of any shares of Capital Stock of the Company either (A) in exchange for Qualified Capital Stock of the Company or (B) through the application of the net cash proceeds received by the Company from (x) a substantially concurrent sale of Qualified Capital Stock of the Company or (y) a contribution to the equity capital of the Company not representing an interest in Disqualified Capital Stock, in each case not received from a Subsidiary of the Company; provided, that the value of any such Qualified Capital Stock issued in exchange for such acquired Capital Stock and any such net cash proceeds shall be excluded from Section 3.9(a)(C)(3) (and were not included therein at any time);

(iii) the voluntary prepayment, purchase, defeasance, redemption or other acquisition or retirement for value of any Subordinated Indebtedness solely in exchange for or through the application of net cash proceeds of a substantially concurrent sale other than to a Subsidiary of the Company, of:

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date, amounts expended pursuant to Section 3.9(b)(i) (without duplication for the declaration of the relevant dividend), Section 3.9(b)(iv), Section 3.9(b)(v) and Section 3.9(b)(vi) shall be included in such calculation and amounts expended pursuant to Section 3.9(b)(ii) and Section 3.9(b)(iii) shall not be included in such calculation.

The amount of any Restricted Payments not in cash shall be the Fair Market Value on the date of such Restricted Payment of the property, assets or securities proposed to be paid, transferred or issued by the Company or the relevant Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment.

Section 3.10 Limitation on Asset Sales.

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

(i) the Company or such 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 sold or otherwise disposed of; and

(ii) at least 75% of the consideration received for the assets sold by the Company or the Restricted Subsidiary, as the case may be, in the Asset Sale is in the form of (1) cash or Cash Equivalents; (2) assets (other than current assets as determined in accordance with Mexican FRS or Capital Stock) to be used by the Company or any Restricted Subsidiary in a Permitted Business; (3) Capital Stock in a Person engaged solely in a Permitted Business that shall become a Restricted Subsidiary as a result of such Asset Sale; or (4) a combination of cash, Cash Equivalents and such assets.

Solely for the purposes of this Section 3.10(a), the following are deemed to be cash or Cash Equivalents: (x) the assumption of Indebtedness of the Company or any Restricted Subsidiary by any Person and the release of the Company or such Restricted Subsidiary from any liability in connection with the Asset Sale; and (y) any securities received by the Company or any Restricted Subsidiary that are promptly converted by the Company or any Restricted Subsidiary into cash or Cash Equivalents.

(b) The Company or such Restricted Subsidiary, as the case may be, may apply the Net Cash Proceeds of any such Asset Sale within 365 days thereof to:

(i) repay, prepay or purchase any Senior Indebtedness of the Company or any Restricted Subsidiary, in each case for borrowed money or constituting a Capitalized Lease Obligation and permanently reduce the commitments with respect thereto without Refinancing; or

(ii) purchase (or enter into a binding agreement to purchase; provided that such purchase is consummated within 90 days after the date that is 365 days after such Asset Sale):

(1) assets (other than current assets as determined in accordance with Mexican FRS or Capital Stock) to be used by the Company or any Restricted Subsidiary in a Permitted Business; or

(2) Capital Stock of a Person engaged solely in a Permitted Business that shall become, upon purchase, a Restricted Subsidiary,

in each case from a Person other than the Company and its Restricted Subsidiaries;

(c) To the extent all or a portion of the Net Cash Proceeds of any Asset Sale are not applied within the 365 days of the Asset Sale as described in Section 3.10(b)(i) or Section 3.10(b)(ii) (or, if a binding agreement has been entered into as set forth in Section 3.10(b)(ii), the date of the expiration of the 90-day period set forth in such Section 3.10(b)(ii)), the Company shall make an offer to purchase Notes (the “Asset Sale Offer”), at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus any accrued and unpaid interest thereon, to the purchase date (the “Asset Sale Offer Amount”). The Company shall purchase pursuant to an Asset Sale Offer from all tendering

Holders on a pro rata basis, and, at the Company’s option, on a pro rata basis with the holders of any other Senior Indebtedness with similar provisions requiring the Company to offer to purchase the other Senior Indebtedness with the proceeds of Asset Sales, that principal amount (or accreted value in the case of Indebtedness issued with original issue discount) of Notes and the other Senior Indebtedness to be purchased equal to such unapplied Net Cash Proceeds. The Company may satisfy its obligations under this Section 3.10 with respect to the Net Cash Proceeds of an Asset Sale by making an Asset Sale Offer prior to the expiration of the relevant 365-day period.

(d) The purchase of Notes pursuant to an Asset Sale Offer shall occur on a date not less than 20 Business Days following the date thereof, or any longer period as may be required by applicable law or regulation, nor more than 60 days following the 365th day following the Asset Sale (or, if a binding agreement has been entered into as set forth in Section 3.10(b)(ii), not more than 60 days following the date of the expiration of the 90-day period set forth in Section 3.10(b)(ii)). The Company may, however, defer an Asset Sale Offer until there is an aggregate amount of unapplied Net Cash Proceeds from one or more Asset Sales equal to or in excess of U.S.$25.0 million (or the equivalent in other currencies). At that time, the entire amount of unapplied Net Cash Proceeds, and not just the amount in excess of U.S.$25.0 million (or the equivalent in other currencies), shall be applied as required pursuant to this Section 3.10. Pending application in accordance with this Section 3.10, Net Cash Proceeds shall be applied to temporarily reduce revolving credit borrowings, if any, that can be re-borrowed or Invested in Cash Equivalents.

(e) Upon receiving the Asset Sale Offer Notice, Holders may elect to tender their Notes in whole or in part in integral multiples of U.S.$1,000 in exchange for cash; provided that the principal amount of each such tendering Holder’s Note shall not be less than U.S.$100,000.

(f) On the Asset Sale Offer Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all Notes or portions thereof properly tendered pursuant to the Asset Sale Offer;

(ii) deposit with the Paying Agent funds in an amount equal to the Asset Sale Offer Amount in respect of all Notes or portions thereof so tendered; and

(g) To the extent that Holders of Notes and holders of other Senior Indebtedness, if any, which are the subject of an Asset Sale Offer properly tender and do not withdraw Notes or the other Senior Indebtedness in an aggregate amount exceeding the amount of unapplied Net Cash Proceeds, the Company shall purchase the Notes and the other Senior Indebtedness on a pro rata basis (based on amounts tendered). If only a portion of a Note is purchased pursuant to an Asset Sale Offer, a new Note in a principal amount equal to the portion

thereof not purchased shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate). Notes (or portions thereof) purchased pursuant to an Asset Sale Offer shall be cancelled and cannot be reissued.

(h) Upon completion of an Asset Sale Offer, the amount of Net Cash Proceeds shall be reset at zero. Accordingly, to the extent that the aggregate amount of Notes and other Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the aggregate amount of unapplied Net Cash Proceeds, the Company may use any remaining Net Cash Proceeds for general corporate purposes of the Company and its Restricted Subsidiaries.

(i) In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under Section 4.1 the Surviving Entity shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this Section 3.10, and shall comply with the provisions of this Section 3.10 with respect to the deemed sale as if it were an Asset Sale. In addition, the Fair Market Value of properties and assets of the Company or its Restricted Subsidiaries so deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section 3.10.

(j) For the purposes of this Section 3.10, if at any time, any non-cash consideration received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any non-cash consideration), the conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this covenant within 365 days of conversion or disposition.

(k) The Company shall comply with the requirements of Rule 14e-l under the Exchange Act and any other applicable securities laws in connection with the purchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 3.10, the Company shall comply with those laws and regulations and shall not be deemed to have breached its obligations under this Section 3.10 by doing so.

Section 3.11 Limitation on Designation of Unrestricted Subsidiaries.

(a) The Company may designate after the Issue Date any Subsidiary of the Company as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(i) no Default or Event of Default has occurred and is continuing at the time of or after giving effect to such Designation and any transactions between the Company or any of its Restricted Subsidiaries and such Unrestricted Subsidiary are in compliance with Section 3.14;

(ii) at the time of and after giving effect to such Designation, the Company could Incur U.S.$1.00 of additional Indebtedness pursuant to Section 3.8(a); and

(iii) the Company would be permitted to make an Investment at the time of Designation (assuming the effectiveness of such Designation and treating such Designation as an Investment at the time of Designation) as a Restricted Payment pursuant to Section 3.9(a) in an amount (the “Designation Amount”) equal to the amount of the Company’s Investment in such Subsidiary on such date.

(b) The Company may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “Revocation”) only if:

(i) no Default or Event of Default has occurred and is continuing at the time of and after giving effect to such Revocation; and

(ii) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if Incurred at such time, have been permitted to be Incurred for all purposes of this Indenture.

(c) The Designation of a Subsidiary of the Company as an Unrestricted Subsidiary shall be deemed to include the Designation of all of the Subsidiaries of such Subsidiary. All Designations and Revocations must be evidenced by a Board Resolution of the Board of Directors of the Company and an Officers’ Certificate, delivered to the Trustee certifying compliance with the preceding provisions.

Section 3.12 Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a) Except as provided in Section 3.12(b), the Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:

(vi) restrictions in other Indebtedness incurred by a Restricted Subsidiary of the Company in compliance with Section 3.8; provided that such restrictions are not materially more restrictive with respect to such encumbrances and restrictions than those applicable to Restricted Subsidiaries in agreements related to Indebtedness referenced in Section 3.12(b)(ii);

(vii) customary restrictions on cash or other deposits imposed by customers under contracts or other arrangements entered into or agreed to in the ordinary course of business;

(viii) customary non-assignment provisions of any license or other contract and customary provisions restricting assignment or subletting in any lease governing a leasehold interest of any Restricted Subsidiary, or any customary restriction on the ability of a Restricted Subsidiary to dividend, distribute or otherwise transfer any asset that is subject to a Lien that secures Indebtedness, in each case permitted to be Incurred under this Indenture;

(ix) restrictions with respect to a Restricted Subsidiary of the Company imposed pursuant to a binding agreement which has been entered into for the sale or disposition of Capital Stock or assets of such Restricted Subsidiary; provided that such restrictions apply solely to the Capital Stock or assets of such Restricted Subsidiary being sold;

Section 3.14 Limitation on Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an “Affiliate Transaction”), unless:

(a) In the event that the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market, the Company shall use its commercially reasonable efforts to maintain such listing; provided that if, as a result of the European Union regulated market amended Directive 2001/34/EC (the “Transparency Directive”) or any legislation implementing the Transparency Directive or other directives or legislation, the Company could be required to publish financial information either more regularly than it otherwise would be required to or according to accounting principles which are materially different from the accounting principles which the Company would otherwise use to prepare its published financial information, the Company may delist the Notes from the Luxembourg Stock Exchange in accordance with the rules of such Exchange and seek an alternative admission to listing, trading and/or quotation for the Notes on a different section of the Luxembourg Stock Exchange or by such other listing authority, stock exchange and/or quotation system inside or outside the European Union as the Board of Directors of the Company may decide.

Section 3.19 Payment of Additional Amounts.

(a) The Company and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee shall pay to Holders of the Notes such additional amounts (“Additional Amounts”) as may be necessary so that every net payment of interest (including any premium paid upon redemption of the Notes and any discount deemed interest under Mexican law) or principal to the Holders shall not be less than the amount provided for in the Notes. The term, “net payment,” means the amount that the Company, any Restricted Subsidiary that provides a Subsidiary Guarantee or a Paying Agent pays any Holder after deducting or withholding an amount for or on account of any present or future taxes, duties, assessments or other governmental charges (“Taxes”) imposed with respect to that payment by Mexico or any political subdivision or taxing authority of any nature thereof or therein (“Taxing Authority”).

(b) The Company and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee, shall not pay Additional Amounts to any Holder for or solely on account of any of the following:

(ii) any estate, inheritance, gift or similar tax, assessment or other governmental charge imposed with respect to the Notes;

(iii) any Taxes imposed solely because the Holder or any other Person fails to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico, for tax purposes, of the Holder or any beneficial owner of the Note if compliance is required by law, regulation thereunder or by an applicable income tax treaty to which Mexico is a party, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and the Company has given the Holders at least 30 days’ notice that Holders shall be required to provide such information and identification;

(iv) any Taxes payable otherwise than by deduction or withholding from payments on the Notes;

(v) any Taxes with respect to a Note presented for payment more than 30 days after the date on which the payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of such Note would have been entitled to such Additional Amounts on presenting such Note for payment on any date during such 30-day period;

(vi) any withholding or deduction imposed on a payment to or for the benefit of an individual that is required to be made pursuant to European Council Directive 2003/48/EC or any other Directive on the taxation of savings implementing the conclusion of the ECOFIN council meeting on November 26-27, 2000, or any law implementing or complying with, or introduced in order to conform to, such Directive;

(vii) any withholding or deduction that is imposed on a Note presented for payment by or on behalf of a beneficial owner who would have been able to avoid the withholding or deduction by presenting the Note to another paying agent in a Member State of the European Union; and

(viii) any payment on the Note to a Holder that is a fiduciary or partnership or a person other than the sole beneficial owner of any such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of the payment would not have been entitled to the Additional Amounts had the beneficiary, settlor, member or beneficial owner been the Holder of the Note.

(c) The limitations on the obligations of the Company and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee to pay Additional Amounts set forth in Section 3.19(b)(iii) shall not apply:

(i) if the provision of information, documentation or other evidence described in such Section 3.19(b)(iii) 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, than comparable information or other reporting requirements imposed under U.S. tax law (including the United States-Mexico income tax treaty), regulations and administrative practice; or

(ii) if the provisions of Article 195, Section II of the Mexican Income Tax Law (Ley de Impuestos Sobre la Rentd) (or a substitute or equivalent provision) is in effect, unless (A) the provision of the information, documentation or other evidence described in such Section 3.19(b)(iii) is expressly required by the applicable Mexican laws and regulations in order to apply such Article 195, Section II (or substitute or equivalent provision), (B) the Company or any Restricted Subsidiary cannot obtain the information, documentation or other evidence necessary to comply with the applicable Mexican laws and regulations on its own through reasonable diligence and (C) the Company or any Restricted Subsidiary otherwise would meet the requirements for application of the applicable Mexican laws and regulations.

In addition, such Section 3.19(b)(iii) does not require, and shall not be construed to require, that any Person, including any non-Mexican pension fund, retirement fund or financial institution, register with the Mexican Ministry of Finance and Public Credit to establish eligibility for an exemption from, or a reduction of, Mexican withholding tax.

(d) Promptly upon request, the Company or any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee shall provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of Mexican taxes in respect of which the Company or such Restricted Subsidiary has paid any Additional Amount. The Company shall make copies of such documentation available to the Holders of the Notes or the Paying Agent upon request.

(e) In the event of any merger or other transaction described and permitted under Section 4.1, then all references to Mexico, Mexican law or regulations, and Mexican political subdivisions or taxing authorities under this Section 3.19 and under Article V and Section 5 of Exhibit A shall be deemed to also include the United States and any political subdivision therein or thereof, U.S. law or regulations, and any taxing authority of the United States or any political subdivision therein or thereof, respectively.

Section 3.20 Compliance Certificates. The Company shall deliver to the Trustee within 105 days after the end of each fiscal year of the Company an Officers’ Certificate signed by any two of its principal executive officer, its principal financial officer and its principal accounting officer stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default or Event of Default and whether or not the signers know of any Default or Event of Default that occurred during such period.

Section 6.2 Acceleration.

(a) If an Event of Default (other than an Event of Default specified in Section 6.1(a)(viii) with respect to the Company) has occurred and is continuing, the Trustee or the Holders of at least 25% in principal amount of Outstanding Notes may declare the unpaid principal of and accrued and unpaid interest on all the Notes to be immediately due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a “notice of acceleration.” If an Event of Default specified in Section 6.1(a)((viii) occurs with respect to the Company, then the unpaid principal of and accrued and unpaid interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b) At any time after a declaration of acceleration with respect to the Notes as described in Section 6.2(a), the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences:

(i) if the rescission would not conflict with any judgment or decree;

(ii) if all existing Events of Default have been cured or waived, except nonpayment of principal or interest that has become due solely because of the acceleration;

(iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; and

(b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.4 Waiver of Past Defaults. Subject to Section 6.2, the Holders of a majority in principal amount of the Outstanding Notes may waive any existing Default or Event of Default hereunder, and its consequences, except a default in the payment of the principal of or interest on any Notes.

provided that a Holder of a Note may institute suit for enforcement of payment of the principal of or interest on such Note on or after the respective due dates expressed in such Note. Notwithstanding any provision of this Indenture to the contrary, no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb, or prejudice the rights of any other of such Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Section 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision hereof (including, without limitation, Section 6.6), the right of any Holder to receive payment of principal of or interest on the Notes held by such Holder, on or after the respective due dates, Redemption Dates or repurchase date expressed herein or the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.8 Collection Suit by Trustee. If an Event of Default specified in Section 6.1(a)(i) and Section 6.1(a)(ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with applicable interest on any overdue principal and, to the extent lawful, interest on overdue interest) and the amounts provided for in Section 7.7.

Section 6.9 Trustee May File Proofs of Claim, etc.

(a) In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee may (irrespective of whether the principal of the Notes is then due):

(i) 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 and the Holders under this Indenture and the Notes allowed in any bankruptcy, insolvency, liquidation or other judicial proceedings relative to the Company, any Subsidiary Guarantor or any Subsidiary of the Company or their respective creditors or properties; and

(ii) collect and receive any moneys or other property payable or deliverable in respect of any such claims and distribute them in accordance with this Indenture.

Any receiver, trustee, liquidator, sequestrator (or other similar official) in any such 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, taxes, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due to the Trustee pursuant to Section 7.7.

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

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

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

THIRD: to the Company or, to the extent the Trustee collects any amount pursuant to any Subsidiary Guarantee from any Subsidiary Guarantor, to such Subsidiary Guarantor.

The Trustee may, upon notice to the Company, fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs. All parties agree, and each Holder by its acceptance of its Notes shall be deemed to have agreed, that 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 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 in the manner and to the extent provided in the Trust Indenture Act. This Section 6.11 does not apply to a suit by the Trustee, a suit by the Company, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in principal amount of Outstanding Notes.

Section 7.3 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 of its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar or co-Registrar may do the same with like rights. However, the Trustee must comply with Section 7.10 and Section 7.11.

Section 7.4 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in

connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder.

Section 7.5 Notice of Defaults.

Section 7.6 Reports by Trustee to Holders. The Trustee shall comply with Section 313 of the Trust Indenture Act (with the exception of Section 313(d)). The Company agrees to promptly notify the Trustee whenever the Notes become listed on any stock exchange and of any delisting thereof.

Section 7.7 Compensation and Indemnity.

(a) The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it in connection with the performance of its duties under this Indenture, except for any such expense as may arise from the Trustee’s negligence, willful misconduct or bad faith.

(b) The Company shall indemnify the Trustee against any and all loss, damage, claim, liability or expense (including reasonable attorneys’ fees and expenses) incurred by it without negligence, willful misconduct or bad faith on its part in connection with the acceptance and administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the Trustee in connection with such defense. The Company need not pay for any settlement made without its written consent.

(c) To secure the Company’s payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.7 shall not be subordinate to any other liability or Indebtedness of the Company.

(d) The Company’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Bankruptcy Law Event of Default, the expenses are intended to constitute expenses of administration under any Bankruptcy Law; provided, however, that this shall not affect the Trustee’s rights as set forth in this Section 7.7 or Section 6.10.

(c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders and, so long as the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market and the rules of such Exchange so require, the successor Trustee shall also publish notice as described in Section 10.1. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

(d) If a successor ▇▇▇▇▇▇▇ does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Outstanding Notes may petition, at the Company’s expense, any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

Section 7.9 Successor Trustee by ▇▇▇▇▇▇.

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or national banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee; provided that such Persons shall be otherwise qualified and eligible under this Article VII.

(b) In case at the time such successor or successors to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have.

Section 7.10 Eligibility; Disqualification.

(a) The Trustee shall at all times satisfy the requirements of Section 310(a) of the Trust Indenture Act. The Trustee shall have a combined capital and surplus of at least U.S.$50 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the Trust Indenture Act.

(b) If the Trustee has or acquires a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be Outstanding only for the purposes of the sections of this Indenture referred to in clause (i) or (ii) of this Section 8.1(b), and the Company shall have been deemed to have satisfied all their other obligations under such Notes, and hereunder (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 shall survive until otherwise terminated or discharged hereunder:

(i) the rights of Holders to receive solely from the trust described in Section 8.2(a) below, as more fully set forth in such section, payments in respect of the principal of and interest on the Notes when such payments are due,

(ii) the Company’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments,

For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event or Default with respect to the Notes under Section 6.1(a)(iii), but, except as specified above, the remainder hereof and such Notes shall be unaffected thereby.

Section 8.2 Conditions to Defeasance. The Company may exercise its Legal Defeasance option or its Covenant Defeasance option only if:

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

Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company.

(e) To the extent that any of the Company has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property, the Company hereby irrevocably waives and agrees not to plead or claim such immunity in respect of its obligations under this Indenture or the Notes.

(a) U.S. Dollars is the sole currency of account and payment for all sums payable by the Company, and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee, under or in connection with the Notes, this Indenture or such Subsidiary Guarantee. Any amount received or recovered in currency other than U.S. 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, any Subsidiary or otherwise) by any Holder of the Notes in respect of any sum expressed to be due to it from the Company, and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee, shall only constitute a discharge of it under the Notes, this Indenture and the Subsidiary Guarantee only to the extent of the U.S. Dollars 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 U.S. Dollars amount is less than the U.S. Dollars amount expressed to be due to the recipient under the Notes, this Indenture, or the Subsidiary Guarantee, the Company, and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee, shall indemnify the

recipient against any loss sustained by it in making any such purchase. In any event, the Company shall indemnify the Holder against the cost of making any purchase of U.S. Dollars. For the purposes of this Section 10.11, it shall be sufficient for the Holder of a Note to certify in a manner reasonably satisfactory to the Company that it would have suffered a loss had an actual purchase of U.S. Dollars been made with the amount received in that other currency on the date of receipt or recovery (or, if a purchase of U.S. Dollars on such date had not been practicable, on the first date on which it would have been practicable) and that the change of the purchase date was needed.

(b) The indemnities of the Company, and any Restricted Subsidiary which after the Issue Date provides a Subsidiary Guarantee, contained in this Section 10.11, to the extent permitted by law: (i) constitute a separate and independent obligation from the other obligations of the Company and the Restricted Subsidiaries under this Indenture and the Notes; (ii) shall give rise to a separate and independent cause of action against the Company; (iii) shall apply irrespective of any indulgence granted by any Holder of the Notes from time to time; and (iv) shall continue in full force and effect notwithstanding any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under the Notes.

Section 10.12 Table of Contents; Headings. The table of contents and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

Section 10.13 Conflict of Any Provision of Indenture with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

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

The Company shall pay interest semiannually in arrears on each Interest Payment Date of each year, commencing on February 11, 2010. Interest on the Notes shall accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from August 11, 2009. The Company shall pay interest on overdue principal (plus interest on such interest to the extent lawful), at the rate borne by the Notes to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and, to the extent such payments are lawful, interest on overdue installments of interest (“Defaulted Interest”) without regard to any applicable grace periods at the rate shown on this Note, as provided in the Indenture.

All payments made by the Company in respect of the Notes shall be made free and clear of and without deduction or withholding for or on account of any Taxes imposed or levied by or on behalf of any Taxing Authority, unless such withholding or deduction is required by law or by the interpretation or administration thereof. In that event, the Company shall pay to each Holder of the Notes Additional Amounts as provided in the Indenture subject to the limitations set forth in the Indenture.

The terms of the Notes include those stated in the Indenture. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of those terms. Each Holder by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as amended or supplemented from time to time.

The Notes are senior unsecured obligations of the Company. Subject to the conditions set forth in the Indenture and without the consent of the Holders, the Company may issue Additional Notes. All Notes shall be treated as a single class of securities under the Indenture.

The Indenture imposes certain limitations on, among other things, the ability of the Company and its Subsidiaries to Incur Additional Indebtedness, make Restricted Payments, incur Liens, make Asset Sales, enter into transactions with Affiliates, or consolidate or merge or transfer or convey all or substantially all of the Company’s and its Subsidiaries’ assets.

5.	Optional Redemption

(a) Optional Make- Whole Redemption. The Company shall have the right, at its option, to redeem the Notes, in whole but not in part, at any time prior to their maturity at a redemption price equal to the greater of (1) 100% of the principal amount of such Notes and (2) the sum of the present value of each remaining scheduled payment of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points (the “Make-Whole Amount”), plus in each case any accrued interest on the principal amount of the Notes to the date of redemption.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

A-6

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Notes.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company.

“Comparable Treasury Price” means, with respect to any redemption date (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotation or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means Citigroup Global Markets Inc. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated or their affiliates which are primary United States government securities dealers and not less than two other leading primary United States government securities dealers in New York City reasonably designated by the Company; provided that if any of the foregoing cease to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked price for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 pm New York time on the third Business Day preceding such redemption date.

(b) Optional Redemption Upon Eligible Equity Offerings. At any time, prior to or on August 11, 2012, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more Eligible Equity Offerings to redeem up to 35% of the aggregate principal amount of the Outstanding Notes (including any Additional Notes) at a redemption price equal to 111.75% of the principal amount on the redemption date, plus any accrued and unpaid interest to the redemption date; provided that:

(i)

after giving effect to any such redemption at least 65% of the aggregate principal amount of the Notes (including any Additional Notes) issued under the Indenture remains outstanding; and

(ii)

the Company shall make such redemption not more than 60 days after the consummation of such Eligible Equity Offering.

“Eligible Equity Offering” means the issuance and sale for cash of Qualified Capital Stock of the Company to any Person other than an Affiliate of the Company pursuant to (i) a public offering in accordance with U.S. or Mexican laws, rules and regulations, or (ii) a private offering in accordance with Rule 144A and Regulation S under the Securities Act.

A-7

(c) Optional Redemption Upon Tax Event. If, as a result of any amendment to, or change in, the laws (or any rules or regulations thereunder) of Mexico or any political subdivision or taxing authority thereof or therein affecting taxation, or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment to or change of such laws, rules or regulations becomes effective on or after the Issue Date, the Company would be obligated, after taking all reasonable measures to avoid this requirement, to pay any Additional Amounts in excess of those attributable to a Mexican withholding tax rate of 4.9% with respect to the Notes, then, at the Company’s option, all, but not less than all, of the Notes may be redeemed at any time at a redemption price equal to 100% of the outstanding principal amount, plus any accrued and unpaid interest and any Additional Amounts to the redemption date due thereon up to but not including the date of redemption; provided that (1) no notice of redemption for tax reasons may be given earlier than 60 days prior to the earliest date on which the Company would be obligated to pay these Additional Amounts if a payment on the Notes were then due, and (2) at the time such notice of redemption is given such obligation to pay such Additional Amounts remains in effect.

Prior to the publication of any notice of redemption pursuant to this provision, the Company shall deliver to the Trustee:

(i)

an Officers’ Certificate stating that the Company is entitled to effect the redemption and setting forth a statement of facts showing that the conditions precedent to the Company’s right to redeem have occurred, and

(ii)

an Opinion of Counsel from Mexican legal counsel (which may be the Company’s counsel) of recognized standing to the effect that the Company has or shall become obligated to pay such Additional Amounts as a result of such change or amendment.

This notice, once delivered by the Company to the Trustee, shall be irrevocable.

The Company shall give notice of any redemption at least 30 days (but not more than 60 days) before the redemption date to the Trustee, which shall, in turn, provide notice to Holders of Notes as set forth below.

(d) Optional Redemption Procedures. In the event that less than all of the Notes are to be redeemed at any time, selection of Notes for redemption shall be made by the Trustee in compliance with the requirements governing redemptions of the principal securities exchange, if any, on which Notes are listed or if such securities exchange has no requirement governing redemption or the Notes are not then listed on a securities exchange, on a pro rata basis, by lot or by any other method as the Trustee shall deem fair and appropriate. No Notes of a principal amount of U.S.$100,000 or less may be redeemed in part and Notes of a principal amount in excess of U.S.$100,000 may be redeemed in part in multiples of U.S.$1,000 only.

Notice of any redemption shall be mailed by first-class mail, postage prepaid, at least 30 but not more than 60 days before the redemption date to Holders of Notes to be redeemed at their respective registered addresses. If Notes are to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed. For

A-8

so long as the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market, and the rules of such Exchange require, the Company shall cause notices of redemption to also be published as provided under Section 10.1 of the Indenture. A new Note in a principal amount equal to the unredeemed portion thereof, if any, shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate).

Notes called for redemption shall become due on the date fixed for redemption. The Company shall pay the redemption price for any Note together with accrued and unpaid interest thereon through the date of redemption. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to the Indenture. Upon redemption of any Notes by the Company, such redeemed Notes shall be cancelled.

6.	Mandatory Repurchase Provisions

(a) Change Of Control Offer. Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require that the Company purchase all or a portion (in integral multiples of U.S.$1,000) of the Holder’s Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest through the date of purchase. Within 30 days following the date upon which the Change of Control occurred, the Company must make a Change of Control Offer pursuant to a Change of Control Notice and, so long as the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market, and the rules of such Exchange so require, publish the Change of Control Offer in a newspaper having general circulation in Luxembourg. As more fully described in the Indenture, the Change of Control Notice shall state, among other things, the Change of Control Payment Date, which must be no earlier than 30 days nor later than 60 days from the date the notice is mailed, other than as may be required by applicable law.

(b) Asset Sale Offer. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to make Asset Sales.

The registered holder of this Note may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

10.	Discharge Prior to Redemption or Maturity

Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Notes and the Indenture if the Company deposits with the Trustee U.S. Dollars or U.S. Government Obligations for the payment of principal of and interest on the Notes to redemption or maturity, as the case may be.

A-10

12.	Defaults and Remedies

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default, which shall result in the Notes being due and payable immediately upon the occurrence of such Events of Default.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal or interest) if it determines that withholding notice is in their interest.

13.	Trustee Dealings with the Company

Subject to certain limitations set forth in the Indenture and the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

14.	No Recourse Against Others

No past, present or future incorporator, director, officer, employee, shareholder or controlling person, as such, of the Company shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claims based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

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

This Supplemental Indenture, dated as of [ ] (this “Supplemental Indenture”), among [name of Restricted Subsidiary], a [ ] [corporation] [limited liability company] (the “Subsidiary Guarantor”), Alestra, S. de ▇.▇. de C.V., a limited liability company with variable capital (sociedad de responsabilidad limitada de capital variable) organized and existing under the laws of the United Mexican States (together with its successors and assigns, the “Company”) and The Bank of New York Mellon, as Trustee under the Indenture referred to below.

W I T N E S S E T H:

WHEREAS, the Company and the Trustee have heretofore executed and delivered an Indenture, dated as of August 11, 2009 (as amended, supplemented, waived or otherwise modified, the “Indenture”), providing for the issuance of 11.750% Senior Notes due 2014 of the Company (the “Notes”);

WHEREAS, pursuant to Section 3.16 of the Indenture, the Company shall not permit any of its Restricted Subsidiaries, directly or indirectly, by way of the pledge of any intercompany note or otherwise, to assume, guarantee or in any other manner become liable with respect to any Indebtedness of the Company or any other Restricted Subsidiary of the Company (other than Indebtedness under Hedging Obligations in reliance of Section 3.8 of the Indenture), or to incur any Indebtedness unless, in any such case such Restricted Subsidiary executes and delivers to the Trustee a Subsidiary Guarantee pursuant to which such Restricted Subsidiary shall unconditionally guarantee, jointly and severally with any other Subsidiary Guarantors’, the Company’s full and prompt payment of the Obligations (as defined in the Indenture) in respect of the Indenture and the Notes; and

WHEREAS, pursuant to Section 9.1 of the Indenture, the Trustee and the Company are authorized to execute and deliver this Supplemental Indenture to supplement the Indenture, without the consent of any Holder;

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

ARTICLE I

DEFINITIONS

Section 1.1. Defined Terms. Unless otherwise defined in this Supplemental Indenture, terms defined in the Indenture are used herein as therein defined.

E-1

ARTICLE II

AGREEMENT TO BE BOUND; GUARANTEE

Section 2.1. Agreement to be Bound. The Subsidiary Guarantor hereby becomes a party to the Indenture as a Subsidiary Guarantor and as such shall have all of the rights and be subject to all of the obligations and agreements of a Subsidiary Guarantor under the Indenture. The Subsidiary Guarantor hereby agrees to be bound by all of the provisions of the Indenture applicable to a Subsidiary Guarantor and to perform all of the obligations and agreements of a Subsidiary Guarantor under the Indenture.

Section 2.2. Subsidiary Guarantee.

(a) The Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the Obligations (such guaranteed Obligations, the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be modified in any manner, extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this supplemental indenture notwithstanding any modification, extension or renewal of any Obligation. Each Subsidiary Guarantor hereby agrees to pay, in addition to the amounts stated above, any and all expenses (including reasonable counsel fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under any Subsidiary Guarantee.

(b) Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

(c) The obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

(d) Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

E-2

(e) In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against each Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of:

(i) the unpaid amount of such Obligations then due and owing; and

(ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law).

(f) Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand:

(i) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby; and

(ii) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of its Subsidiary Guarantee.

Section 2.3. Waivers. The Subsidiary Guarantor hereby waives presentation to, demand of payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. The Subsidiary Guarantor waives notice of any default under the Notes or the Obligations. The obligations of the Subsidiary Guarantor hereunder shall not be affected by (i) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under the Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of the Indenture, the Notes or any other agreement; (iv) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (v) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (vi) any change in the ownership of the Company.

The Subsidiary Guarantor further expressly waives irrevocably and unconditionally:

(i) Any right it may have to first require any Holder to proceed against, initiate any actions before a court of law or any other judge or authority, or enforce or complete the enforcement of any other rights or security (or apply as payment on such security) or claim, or complete any claim for, payment from the Company

E-3

(ii) or any other Person (including any Subsidiary Guarantor or any other guarantor) before claiming from it under this Supplemental Indenture;

(iii) Any right to which it may be entitled to have the assets of the Company or any other Person (including any Subsidiary Guarantor or any other guarantor) first be used, applied or depleted as payment of the Company’s or the Subsidiary Guarantors’ obligations under the Indenture, prior to any amount being claimed from or paid by any of the Subsidiary Guarantors thereunder;

(iv) Any right to which it may be entitled to have claims hereunder divided between the Subsidiary Guarantors or between any Subsidiary Guarantor s and the Company; and

(v) To the extent applicable, the benefits of orden, excusión, division, quita and espera and any right specified in articles 2814, 2815, 2817, 2818, 2819, 2820, 2821, 2822, 2823, 2826, 2837, 2838, 2839, 2840, 2845, 2846, 2847 and any other related or applicable articles that are not explicitly set forth herein because of Subsidiary Guarantor ‘s knowledge thereof of the Código Civil Federal of Mexico, and the Código Civil of each State of the Mexican Republic and the Federal District of Mexico.

The obligations assumed by each Subsidiary Guarantor hereunder shall not be affected by the absence of judicial request of payment by a Holder to the Company or by whether any such person takes timely action pursuant to articles 2848 and 2849 of the Código Civil Federal of Mexico and the Código Civil of each State of the Mexican Republic and the Federal District of Mexico and each Subsidiary Guarantor hereby expressly waives the provisions of such articles.

Section 2.4. Limitation on Liability; Termination, Release and Discharge.

(a) The obligations of each Subsidiary Guarantor hereunder shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the Obligations not constituting a fraudulent conveyance, fraudulent transfer or similar illegal transfer under applicable law.

(b) Each Subsidiary Guarantor shall be released and relieved of its obligations under its Subsidiary Guarantee in the event that:

(i) there is a sale or other disposition of Capital Stock of such Subsidiary Guarantor or all or substantially all of the assets of such Subsidiary Guarantor are sold or otherwise disposed of (including by way of merger or consolidation), following which such Subsidiary Guarantor is no longer a direct or indirect Subsidiary (other than a Receivables Subsidiary) of the Company;

(ii) such Subsidiary Guarantor is designated as an Unrestricted Subsidiary in accordance with Section 3.11 of the Indenture;

E-4

provided that such transaction is carried out pursuant to, and in accordance with, the applicable provisions of the Indenture.

Section 2.5. Right of Contribution. Each Subsidiary Guarantor that makes a payment or distribution under a Subsidiary Guarantee shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount, based on the net assets of each Subsidiary Guarantor determined in accordance with Mexican FRS. The provisions of this Section 2.5 shall in no respect limit the obligations and liabilities of each Subsidiary Guarantor to the Trustee and the Holders and each Subsidiary Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Subsidiary Guarantor hereunder.

Section 2.6. No Subrogation. Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Guaranteed Obligations until payment in full in cash or Cash Equivalents of all Obligations. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full in cash or Cash Equivalents, such amount shall be held by such Subsidiary Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Trustee in the exact form received by such Subsidiary Guarantor (duly endorsed by such Subsidiary Guarantor to the Trustee, if required), to be applied against the Obligations.

ARTICLE III
