A Company Order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is limited to U.S.$[______________].

(d) The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Notes. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent.

(e) In case a Surviving Entity has executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of the Notes authenticated or delivered prior to such transaction may, from time to time, at the request of the Surviving Entity, be exchanged for other Notes executed in the name of the Surviving Entity with such changes in phraseology and form as may be appropriate, but otherwise identical to the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Order of the Surviving Entity, shall authenticate and deliver Notes as specified in such order for the purpose of such exchange.

If the Company or any Restricted Subsidiary or an Affiliate of the Company or any Restricted Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund.

executed by the Holder thereof or his attorney duly authorized in writing.

(iv) 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.

by the Company to the Trustee of the proposed payment pursuant to this Section 2.12(b), such manner of payment shall be deemed practicable by the Trustee.

(c) The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that neither the Company nor the Trustee shall have any responsibility for any defect in the “CUSIP” number that appears on any Note, check, advice of payment or redemption notice, and any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers.

(b) the Company shall cause all shares of Capital Stock of such Restricted Subsidiary owned by the Company or any Restricted Subsidiary to be pledged pursuant to the Collateral Documents and shall create in favor of the Collateral Agent for the benefit of the Holders, as security for the Obligations, perfected (inscritas) pledges of and security interests in all such Capital Stock with the priorities set forth in the Collateral Documents.

The Company also agrees to provide to the Trustee, from time to time upon request, evidence reasonably satisfactory to the Trustee as to the perfection (inscripción) (to the extent perfected (inscrito) at such time), as a first-priority Lien, and priority of the Liens created or intended to be created by this Indenture and the Collateral Documents.

(c) After the Issue Date, if any assets that would otherwise constitute Collateral (including any real property or improvements thereto or any interest therein) are acquired by or become assets of the Company or any Restricted Subsidiary, the Company shall promptly notify the Trustee and, to the extent not otherwise subject to a Lien securing the Obligations, cause such assets to become subject to a first-priority Lien securing the Notes and shall take, and cause each Restricted Subsidiaries to take, such actions as shall be necessary to create such Liens, including actions described in Section 3.18(b).

(ii) 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 3.6(a) in an amount (the “Designation Amount”) equal to the amount of the Company’s Investment in such Subsidiary on such date.

(b) Neither the Company nor any Restricted Subsidiary shall at any time:

(i) provide credit support for, subject any of its property or assets (other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, or Guarantee, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness);

(ii) be directly or indirectly liable for any Indebtedness of any Unrestricted Subsidiary; or

(iii) be directly or indirectly liable for any Indebtedness which provides that the holder thereof may (upon notice, lapse of time or both) declare a default thereon or cause the payment thereof to be accelerated or payable prior to its final scheduled maturity upon the occurrence of a default with respect to any Indebtedness of any Unrestricted Subsidiary,

except:

(1) in the case of Section 3.19(b)(i), Section 3.19(b)(ii) or Section 3.19(b)(iii), any pledge by the Company or any Restricted Subsidiary of the Capital Stock of any Unrestricted Subsidiary for which recourse to the Company or any Restricted Subsidiary is limited to such Capital Stock;

(2) in the case of Section 3.19(b)(i) or Section 3.19(b)(ii), to the extent treated and permitted as a Restricted Payment or Permitted Investment in accordance with Section 3.6 and as an Incurrence of Indebtedness permitted under Section 3.4; and

(3) in the case of Section 3.19(b)(iii), to the extent that the ability to declare a default or accelerate the payment is limited to a default or acceleration on the obligation or instrument of the Company or a Restricted Subsidiary treated as a Restricted Payment or Permitted Investment and Incurrence of Indebtedness incurred in accordance with Section 3.19(b)(i).

Section 3.20 Limitation of Applicability of Certain Covenants.

(a) Notwithstanding the foregoing, the obligations of the Company and its Restricted Subsidiaries to comply with the covenants described above under Section 3.4, Section 3.6, Section 3.7, Section 3.9, Section 3.10, Section 3.13, Section 3.14, Section 3.15, Section 3.16, Section 3.17, Section 3.18, Section 3.19, Section 4.1(a)(iii), and Section 5.9 (collectively, the “Suspended Covenants”) shall be suspended and cease to have any further effect during the period (the “Suspended Period”) from and after the first date that the Notes attain an Investment Grade Rating from either S&P or ▇▇▇▇▇’▇ (or Fitch, if either of S&P or ▇▇▇▇▇’▇ ceases to rate the Notes for reasons outside of the control of the Company) and until the date (the “Reversion Date”) on which none of S&P, Fitch or ▇▇▇▇▇’▇ provide the Notes an Investment Grade Rating.

(b) On the Reversion Date, the Company and its Restricted Subsidiaries’ obligation to comply with the Suspended Covenants shall be reinstated; provided, however, that the Suspended Covenants shall not be of any effect with regard to actions of the Company or its Restricted Subsidiaries taken during the Suspended Period, and no Event of Default shall be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspended Period.

(c) On the Reversion Date, all Indebtedness incurred while the Suspended Covenants were suspended shall be classified to have been incurred pursuant to one of the paragraphs set forth in Section 3.4 (to the extent such Indebtedness would be permitted to be incurred thereunder as of the Reversion Date and after giving effect to Indebtedness outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be incurred pursuant to Section 3.4, such Indebtedness shall be deemed to have been outstanding on the Issue Date so that it is classified as permitted under clause (b)(i) of Section 3.4.

Section 3.21 Payment of Additional Amounts.

(a) The Company is required by Mexican law to deduct and to withhold certain Taxes from payments of interest and amounts deemed interest to investors who are not residents of Mexico for tax purposes, and shall pay to any Holder such additional amounts (“Additional Amounts”) on those payments to the extent described in this Section 3.21. To the extent Taxes imposed by Mexico or any political subdivision or taxing authority thereof or therein (“Mexican Taxes”) are required to be withheld or deducted from any payments under the Notes or the Note Guarantees, the Company or the relevant Restricted Subsidiaries (the “Payor,” as applicable) shall pay such Additional Amounts as may be necessary to ensure that the net amount actually received by such Holder after any such withholding or deduction of Mexican Taxes is equal to the amount that the Holder would have received had no such withholding or deduction been required.

(b) The Payor shall not pay Additional Amounts to any Holder for or on account of any of the following:

(i) any Taxes imposed solely because of the existence of any present or former connection between such Holder and Mexico (other than the mere receipt of a payment or the ownership or holding of a Note or enforcement of rights in respect of the Notes);

(ii) any estate, inheritance, gift, sales, transfer 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, information, documentation or other similar reporting requirement if (A) such compliance is required by law, regulation, or administrative practice, or an applicable treaty in effect as a precondition to exemption from, or reduction in the rate of, deduction or withholding of any Taxes for which the Payor is required to pay Additional Amounts, (B) the Holder or such other Person is legally entitled to comply with such reporting requirement and (C) at least 30 days prior to the first Interest Payment Date or Change of Control Payment Date with respect to which the Payor shall apply this Section 3.21(b)(iii), the Company or the Restricted Subsidiaries shall have notified the Holder that the Holder shall be required to comply with such requirement;

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

(v) any Taxes with respect to such 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 Holders 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; and

(vi) 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.

(c) Upon request, the Payor shall provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of any Taxes deducted or withheld (including certified copies of any of returns submitted). The Payor shall make copies of such documentation available to the Holders or the Paying Agent upon request.

(d) Notwithstanding the foregoing, the exceptions to a Payor’s obligation to pay Additional Amounts set forth in Section 3.21(b)(iii) shall not apply if (i) the provision of information, certification, documentation or other evidence described in Section 3.21(b)(iii) would be substantially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of a Note (taking into account any relevant differences between U.S. law, rules, regulations or administrative practice and those of the relevant taxing jurisdiction (Mexico, or any political subdivision or taxing authority thereof or therein)) than comparable information or other reporting requirements imposed under U.S. tax law, regulation and administrative practice (such as IRS Forms W-8BEN and W-9) or (ii) with respect to Taxes imposed by Mexico or any political sub-division or taxing authority thereof, (A) Article 195, Section II, of the Mexican income tax law (or a substantially similar successor of such provision) is in effect, unless the provision of the information, certification, documentation or other similar evidence described in Section 3.21(b)(iii) is expressly required by statute, rule or regulation, or an order of a competent authority based upon any such law or regulation, in order to apply Article 195, Section II, of the Mexican income tax law (or a substantially similar successor of such provision), (B) the Payor cannot obtain such information, certification, documentation or other similar evidence on its own through reasonable diligence and (C) the Payor otherwise would meet the requirements for application of Article 195, Section II, of the Mexican income tax law (or such successor of such provision). In addition, Section 3.21(b)(iii) shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Holder register with the Ministry of Finance and Public Credit for the purpose of establishing eligibility for an exemption from or reduction of Mexican withholding tax or

to require that a Holder or beneficial owner of a Note certify or provide information concerning whether it is or is not a tax-exempt pension or retirement fund.

(e) In the event that Additional Amounts actually paid with respect to the Notes pursuant to the preceding paragraphs are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such Notes, and, as a result thereof, such Holder is entitled to make a claim for a refund or credit of such excess from the authority imposing such withholding tax, then such Holder shall, by accepting such Notes, be deemed to have assigned and transferred all right, title and interest to any such claim for a refund or credit of such excess to the Payor. However, by making such assignment, the Holder makes no representation or warranty that the Payor shall be entitled to receive such claim for a refund or credit and Incurs no other obligation with respect thereto (including Incurring any expenses whatsoever necessary to obtain such refund or taking any other action).

(f) In the event a Payor conducts business in any jurisdiction (an “Additional Taxing Jurisdiction”) other than Mexico or any political subdivision thereof and, as a result, is required by the law of such Additional Taxing Jurisdiction to deduct or withhold any amount on account of taxes imposed by such Additional Taxing Jurisdiction from payments under the Notes or the relevant Note Guarantee, as the case may be, which would not have been required to be so deducted or withheld but for such conduct of business in such Additional Taxing Jurisdiction, then all references to Mexico, Mexican law or regulations, and Mexican taxing authorities under this Section 3.21 and Section 5.8 shall be deemed to also include such Additional Taxing Jurisdiction and any political subdivision thereof, the laws or regulations of such Additional Taxing Jurisdiction and any taxing authority of such Additional Taxing Jurisdiction, respectively.

(g) The Company (or, failing which, the relevant Restricted Subsidiaries) shall pay any present or future stamp, court or documentary taxes, or any other excise or property taxes, charges or similar levies which arise in any jurisdiction from the execution, delivery or registration of the Notes, the Note Guarantees or any other document or instrument referred to therein (other than a transfer of the Notes), or the receipt of any payments with respect to the Notes or the Note Guarantees, excluding any such taxes, charges or similar levies imposed by any jurisdiction other than Mexico or any political subdivision thereof, other than those resulting from, or required to be paid in connection with, the enforcement of the Notes, the Note Guarantees or any other such document or instrument following the occurrence of any Event of Default with respect to the Notes.

(h) The foregoing paragraphs in this Section 3.21 shall survive any termination, defeasance or discharge of the Indenture and shall apply mutatis mutandis to any jurisdiction in which any successor Person to a Payor is organized or any political subdivision or taxing authority or agency thereof or therein.

Section 3.22 Change of Control.

(a) Not later than 75 days following the occurrence of a Change of Control, each Holder shall have the right to require that the Company purchase all or a portion (in integral multiples of U.S.$1.00) of the Holder’s Notes at a purchase price equal to 101.50% of the principal amount thereof, plus accrued and unpaid interest thereon through the date of the purchase (the “Change of Control Payment”).

(b) Within 45 days following the date upon which the Change of Control occurred, the Company shall mail, by first-class mail, to each Holder a Change of Control Notice, with a copy to the Trustee, offering to purchase the Notes as described above (a “Change of Control Offer”). The Change of Control Notice shall state, in addition to the things specified in the definition thereof, the purchase date, which shall be 30 calendar days from the date the Change of Control Notice is mailed, other than as may be required by law (the “Change of Control Payment Date”).

(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 not withdrawn; 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.

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). All amounts under the Notes shall be applied to semi-annual installments of principal payable under the Notes in inverse order of maturity. Notes (or portions thereof) purchased pursuant to a Change of Control Offer shall be cancelled and cannot be reissued.

(d) 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 the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

(e) Holders shall not be entitled to require the Company to purchase their Notes in the event of a takeover, recapitalization, leveraged buyout or similar transaction which is not a Change of Control.

(f) 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 the Change of Control provisions of this Indenture, 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.

(g) The Company’s obligation to make an offer to purchase the Notes as a result of the occurrence of a Change of Control may be waived or modified at any time prior to the occurrence of such Change of Control with the written consent of Holders holding in the aggregate at least a majority of the outstanding principal amount of the Notes.

Section 3.23 Further Instruments and Acts. The Company and each Restricted Subsidiary shall execute and deliver such further instruments and do such further acts as may be required by applicable law or may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

Section 3.24 Waiver of Stay, Extension or Usury Laws. The Company and each Restricted Subsidiary covenants (to the extent that it may lawfully do so) that will not have and will 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 Restricted Subsidiary 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 Restricted Subsidiary hereby expressly waives (to the fullest extent permitted by applicable law) all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(ii) the payment of such Additional Amounts cannot be avoided by the use of any reasonable measures available to the Payor that do not require undue efforts or costs (such reasonable measures to include, without limitation, making payment through a paying agent located in a non-Mexican jurisdiction, but not to include having a non-Mexican entity assume the Payor’s obligations under the Notes); provided that:

(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(b)(iv), the Holders of a majority in principal amount of the Notes may waive any existing Default or Event of Default under this Indenture, and its consequences, except a default in the payment of the principal of, premium, if any, or interest on any Notes.

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 and each Restricted Subsidiary 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 the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, concurso mercantil, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(i) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Notes of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee,

its agents or counsel) and of the Holders and beneficial holders (the “Beneficial Holders”) of the Notes allowed in such judicial proceeding; and

(ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same in accordance with this Indenture; and

any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Notes 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 of Notes, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due to the Trustee under Section 7.7. If any challenge is made to any claim filed by the Trustee, the Trustee shall give notice thereof to the Holders. To the extent that any such challenge requires the identification of any Beneficial Holder, the amount of the Notes beneficially held by any Beneficial Holder or the identification of any person or persons through which any Beneficial Holder holds its beneficial interest in the Notes, the Trustee may attempt, but shall not be required, to obtain such information.

(b) Notwithstanding (x) the foregoing or (y) any proof of claim that may have been filed by the Trustee, the parties hereto acknowledge and agree that the Holder or Beneficial Holder shall have the right to participate individually in any receivership, insolvency, liquidation, bankruptcy, reorganization, concurso mercantil, arrangement, adjustment, composition, or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors, to the extent such participation is permissible under applicable law, and to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same in accordance with this Indenture.

(c) Notwithstanding anything to the contrary herein, and solely for procedural purposes, in the event the Trustee files a proof of claim in a pending concurso mercantil proceeding under Section 6.9(a) above, such proof of claim shall contain the following statements: (i) solely for purposes of such pending concurso mercantil proceeding: (1) the Trustee, for the purpose of such proof of claim only, is acting for all of the Beneficial Holders of the Notes issued by the Issuer pursuant to the Indenture; (2) the Beneficial Holders own and hold their beneficial interests in the Notes directly or indirectly through the Note Custodian; (3) pursuant to Section 6.9(a) above, the Trustee is authorized to file the proof of claim; (4) the Trustee reserves, any and all rights of the Beneficial Holders arising from the proof of claim to participate individually in such proceeding as separate creditors of the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors on account of their beneficial interests in the Notes; (5) in the event that any Beneficial Holder decides to participate individually and directly in such proceeding, as a separate creditor of the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors on account of their beneficial interest in the Notes, then such Beneficial Holder shall (x) evidence its capacity by means of its appearance in the proceeding, with the filing of a power of attorney of its legal representative for such

purposes, in terms of the applicable international treaties and laws of Mexico, and (y) file with the competent court a certificate confirming its beneficial interests, duly signed by the Beneficial Holder and by the custodian or broker through which the corresponding Beneficial Holder holds its beneficial interests directly or indirectly through the Note Custodian, and by the Note Custodian (a “Certificate”), together with any other documents which may be required under the applicable laws of Mexico; (6) the Certificate, together with the proof of claim and such other documents, shall be evidence that each Beneficial Holder is an individual creditor of the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors on account of claims related to its respective beneficial holdings of the Notes; (7) to the extent that any Beneficial Holder participates individually in such proceeding, or otherwise asserts claims that duplicate the claims asserted in the proof of claim filed by the Trustee, then such claims filed by such Beneficial Holders may be deducted from the claims against the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors and will not constitute a duplicative claim upon which a second recovery against the Company or any other obligor upon the Notes or the property of the Company or such other obligor or their creditors could be made; and (ii) that the Trustee is not providing legal advice as to any of the matters contained in this Section 6.9(c) and Beneficial Holders should consult, at their sole cost and expense, their own professionals to determine their rights and how they may participate individually in the proceeding. Whether or not a Beneficial Holder individualizes its claim in any concurso mercantil proceeding, any distribution made in respect of the Notes (whether consisting of other securities or other property) as a result of such concurso mercantil proceeding shall be made solely to the Trustee for further distribution to the Beneficial Holders pursuant to the terms of this Indenture.

(d) Nothing herein contained shall authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Note any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder or Beneficial Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder or Beneficial Holder of a Note in any such proceeding; provided that, if any Beneficial Holder shall:

(i) deliver to the Trustee:

(A) a certificate from the custodian or broker through which such Beneficial Holder holds its beneficial interest in the Notes stating the principal amount of the beneficial interest held by such Beneficial Holder,

(B) a certificate from the Note Custodian through which such custodian or broker holds a beneficial interest in the Notes stating the principal amount of beneficial interest in the Notes held by such broker or custodian; and

(ii) authorize and direct the Trustee to vote, consent to, adopt or take or not to take action on any matter in respect of the claim of such Beneficial Holder and state in reasonable detail the matter on which the Trustee is authorized and directed to take such action,

the Trustee may, in its sole discretion, but shall not be required to, vote, consent to, adopt, take or not take such action with respect to, the principal amount of the beneficial interest in the Notes held by such Beneficial Holder as directed by such Beneficial Holder.

Section 6.9(c) and Section 6.9(d) are intended solely to allow the Trustee to take certain administrative actions with respect to matters necessary to establish the claims of the Holders and Beneficial Holders against the Company and other obligors on the Notes in a concurso mercantil. It does not create an agency or fiduciary relationship between the Trustee and the Beneficial Holders or otherwise give rise to any obligation, liability or duty of the Trustee toward the Beneficial Holders, and the Trustee shall have no such obligation, liability or duty to any Beneficial Holder in connection with its taking or not taking any action described in Section 6.9 (c) and Section 6.9(d).

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:

FIRST: to the Trustee for amounts due under Section 7.7;

SECOND: if the Holders proceed against the Company directly without the Trustee in accordance with this Indenture, to Holders for their collection costs;

THIRD: 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

FOURTH: to the Company or, to the extent the Trustee collects any amount pursuant to ARTICLE IX from any Restricted Subsidiary, to such Restricted Subsidiary, or to such party as a court of competent jurisdiction shall direct.

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. 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. 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.

(a) The Company may, at its option by the resolution of its Board of Directors, at any time, elect to have either paragraph (b) or (c) of this Section 8.1 be applied to all Outstanding Notes upon compliance with the conditions set forth in Section 8.2.

(b) Upon the Company’s exercise under paragraph (a) of this Section 8.1 of the option applicable to this paragraph (b), the Company shall, subject to the satisfaction of the conditions set forth in Section 8.2, be deemed to have been discharged from its obligations with respect to all Outstanding Notes on the date all of the conditions set forth in Section 8.2 are satisfied (hereinafter, “Legal Defeasance”). 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 Section 8.3 and the other Sections of this Indenture referred to in clause (i) or (ii) of this paragraph (b), and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions, which shall survive until otherwise terminated or discharged hereunder:

Each Restricted Subsidiary further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

(b) Each Restricted Subsidiary 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. Each Restricted Subsidiary waives notice of any default under the Notes or the Obligations. The obligations of each Restricted Subsidiary 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 this 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 this 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 Restricted Subsidiary; or (vi) any change in the ownership of the Company.

(e) The obligations of each Restricted Subsidiary 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.

The provisions of this Section 10.3 shall in no respect limit the obligations and liabilities of each Restricted Subsidiary to the Trustee and the Holders and each Restricted Subsidiary shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Restricted Subsidiary hereunder.

Section 10.4 No Subrogation. Each Restricted Subsidiary agrees that it shall not be entitled to any right of subrogation in respect of any Guaranteed Obligations until payment in full of all Obligations. If any amount shall be paid to any Restricted Subsidiary on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Restricted Subsidiary in trust for the Trustee and the Holders, segregated from other funds of such Restricted Subsidiary, and shall, forthwith upon receipt by such Restricted Subsidiary, be turned over to the Trustee in the exact form received by such Restricted Subsidiary (duly endorsed by such Restricted Subsidiary to the Trustee, if required), to be applied against the Obligations.

Section 10.5 Additional Note Guarantees. The Company shall cause any Person that shall become a Restricted Subsidiary (an “Additional Restricted Subsidiary”) to concurrently grant a guarantee (an “Additional Note Guarantee”) of the Company’s obligations under this Indenture and the Notes to the same extent that the Restricted Subsidiaries have guaranteed the Company’s obligations under this Indenture and the Notes by executing a supplemental indenture substantially in the form of Exhibit B, expressly assuming any and all Obligations hereunder and waiving any rights waived hereunder by any Restricted Subsidiary, and providing the Trustee with an Officers’ Certificate and Opinion of Counsel and by executing such

documents described in Section 3.17; provided, however, that each Additional Restricted Subsidiary, shall be automatically and unconditionally released and discharged from its obligations under such Additional Note Guarantee only in accordance with Section 10.2.

Section 12.8 Governing Law, etc.

(a) This Indenture (including each Note Guarantee) and the Notes shall be governed by, and construed in accordance with, the law of the State of New York.

(b) Each of the parties hereto hereby:

(i) agrees that any suit, action or proceeding against it arising out of or relating to this Indenture (including the Note Guarantees) or the Notes, as the case may be, may be instituted in any Federal or state court sitting in the Borough of Manhattan in The City of New York, or in the courts of its corporate domicile in respect of actions brought against it as a defendant;

(ii) waives to the fullest extent permitted by applicable law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding, any claim that any suit, action or proceeding in such a court has been brought in an inconvenient forum, and any right to which it may be entitled on account of its place of residence or domicile;

(iii) irrevocably submits to the jurisdiction of such courts in any suit, action or proceeding;

(iv) agrees that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding may be enforced in the courts of the jurisdiction of which it is subject by a suit upon judgment; and

(v) agrees that service of process by mail to the addresses specified herein shall constitute personal service of such process on it in any such suit, action or proceeding.

(c) The Company and the Restricted Subsidiaries have agreed that service of all writs, claims, process and summonses in any related proceeding brought against it in the State of New York (collectively referred to as a “Related Proceeding”) may be made upon CT Corporation System (the “Process Agent”), and the Company and the Restricted Subsidiaries irrevocably appointed the Process Agent as their agent and true and lawful attorney in fact in its name, place and stead to accept such service of any and all such writs, claims, process and summonses, and have agreed that the failure of the Process Agent to give any notice to them of any such service of process shall not impair or affect the validity of such service or of any judgment based thereon. The Company and the

Restricted Subsidiaries have agreed to maintain at all times an agent with offices in New York City to act as their Process Agent.

(d) To the extent that the Company or any of its revenues, assets or properties shall be entitled, with respect to any Related Proceeding any time brought against it or any of its revenues, assets or properties in the courts identified in this Section 12.8, to any immunity from suit, from the jurisdiction of any such court, from attachment prior to judgment, from attachment in aid of execution of judgment, from execution of a judgment or from any other legal or judicial process or remedy, and to the extent that in any such jurisdiction there shall be attributed such an immunity, the Company has irrevocably agreed not to claim and has irrevocably waived such immunity to the fullest extent permitted by law (including, without limitation, the Foreign Sovereign Immunities Act of 1976 of the United States). The Company has agreed that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding on it and may be enforced in any court to the jurisdiction of which it is subject by a suit upon such judgment, provided that service of process is effected upon it in the manner specified in this Indenture or as otherwise permitted by law.

By accepting a Note, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws of the United States and it is the view of the SEC that such a waiver is against public policy.

(a) If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum due under this Indenture or under the Notes from one currency into another currency, the Company has agreed and each Holder agrees, to the fullest extent that the Company and each Holder may effectively do so, that the rate of exchange used shall be the rate at which, in accordance with normal banking procedures, such Holder could purchase the first currency with such other currency in the city that is the principal financial center of the country of issue of the first currency on the day, two Business Days preceding the day on which final judgment is given, which is also a day on which banks are open in Mexico.

(b) To the extent permitted by applicable law, the Company’s obligation in respect of any sum payable by the Company to a Holder shall, notwithstanding any judgment in a currency, (the “Judgment Currency”), other than that in which such sum is denominated in accordance with the applicable provisions of this Indenture, (the “Security Currency”), be discharged only to the extent that on the Business Day following receipt by such Holder of any sum adjudged to be so due in the Judgment Currency, such Holder may in accordance with normal banking procedures purchase the Security Currency with the Judgment Currency. If the amount of the Security Currency so purchased is less than the sum originally due to such Holder in the Security Currency, determined in the manner set forth above, the Company has agreed, as a separate obligation and notwithstanding any such judgment, to indemnify such Holder against such loss, and if the amount of the Security Currency so purchased exceeds the sum originally due to such Holder, such Holder agrees to remit to the Company such excess; provided, that such Holder shall have no obligation to remit any such excess as long as the Company shall have failed to pay such Holder any obligation due and payable under this Indenture in which case any such excess may be applied to such obligations of the Company under this Indenture or the Notes.

Capitalized terms used herein but not defined herein shall have the meanings given to such terms in the Indenture.

1. Principal and Interest

Grupo Iusacell Celular, S.A. de C.V., a Mexican sociedad anónima de capital variable (together with its successors and assigns under the Indenture, the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum described below.

The Company will pay interest semi-annually in arrears on each Interest Payment Date of each year commencing December 31, 2011. Payments will be made to the persons who are Holders at the close of business on June 15 and December 15, respectively, immediately preceding the applicable Interest Payment Date (the “Record Date”), except that, in the case of the first such payment, if the Issue Date occurs between June 15 and June 30 or between December 15 and December 31, then the Record Date for such first payment will be the Issue Date and such first payment will be made to the persons who are Holders at the close of business on the Issue Date. Interest on the Notes will accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from and including July 1, 2011. Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Company shall pay interest (including post-petition interest in any proceeding under any Insolvency 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 of 2.0% per annum in excess of the rate shown on this Note, as provided in the Indenture.

To the extent Mexican Taxes are required to be withheld or deducted from any such payment, the Company shall pay, as provided for in and subject to the exceptions set forth in the Indenture, such Additional Amounts as may be necessary to ensure that the net amount actually received by the Holder after such withholding or deduction is equal to the amount that the Holder would have received had no such withholding or deduction been required.

2. Method of Payment

Prior to 10:00 a.m. New York City time on the date on which any principal of or interest on any Note is due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal and/or interest.

Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal and interest in Dollars.

Payments in respect of Notes represented by a Global Note (including principal and interest) will be made by the transfer of immediately available funds to the accounts specified by DTC. The Company will make all payments in respect of a Certificated Note (including principal and interest) at the office or agent of the Paying Agent in New York City unless the Company elects to make interest payments by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes may also be made, in the case of a Holder of at least U.S.$1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Optional Redemption for Change in Withholding Taxes. The Company may redeem the Notes, at its option, in whole, but not in part, at any time at a redemption price of 100% of the outstanding principal amount thereof if:

(a)

as a result of any amendment to, or change in, the laws (or any rules or regulations promulgated thereunder) of Mexico (or any political subdivision or taxing authority thereof or therein), or as the direct result of the execution of any amendment to any treaty or treaties affecting taxation of which Mexico (or any political subdivision or taxing authority thereof or therein) is a party, or any amendment to or change in an official interpretation of general applicability or application regarding such laws, rules, regulations or treaties by applicable taxing authorities, which amendment, change, application or interpretation becomes effective after the Issue Date, the Payor has or will be obligated to pay Additional Amounts in respect of the Notes pursuant to the terms and conditions thereof in an aggregate amount (taking into account all Additional Amounts paid or to be paid to all Holders) at least 15% greater than those attributable to the Mexican withholding tax rate imposed on interest payments to Holders as of the Issue Date; and

(b)

the payment of such Additional Amounts cannot be avoided by the use of any reasonable measures available to the Payor that do not require undue efforts or costs; provided that:

(i)

no such notice of redemption may be given earlier than 90 days prior to the earliest date on which the Payor would but for such redemption be obligated to pay such Additional Amounts; and

(ii)

In the case of any partial redemption, selection of the Notes for redemption will be made in accordance with Article V of the Indenture.
